statement: –
This invention relates to an insulative block for housing a contact and to an askembly comprising the insulative block and connector contacts disposed in the block in spaced relation to each other, the assembly being adapted to be applied to conductive terminal pins The assembly is generally of the type described in U S Patents Nos.
3,101,985; 3,206,715; 3,566,341; 3,764,960; and 3,853, 388.
Assemblies of this type have principal application to a hermetically sealed compressor for use in refrigeration and air conditioning The compressor consists of a hermetically sealed housing within which is contained the compressor and a motor for driving the compressor A glass-to-metal seal or a header is fixed in the housing wall and provides three conductive pins extending from the inside to the outside of the housing wall to which electrical connection is made to supply power to the motor within the housing.
A contact assembly may comprise an insulative block or housing having three connector contacts mounted within the block with the contact leads projecting from the block In practice, the assembly is shipped to a motor manufacturer and the leads projecting from the assembly are connected to the three input leads of the motor The motor with leads attached is shipped to a compressor manufacturer where the motor is assembled in the compressor unit and the assembly is applied to the three terminal pins on the interior of the compressor housing During the assembly process, the assembly is applied to the pins a number of times, for example, at various testing stages and, of course, on the compressor unit itself Thus, it is of primary importance that the assembly have a high degree of reliability to be able to withstand the rigors of the assembly process Among other things, it is of primary importance that the connector contacts be securely locked in the block to resist pullout of the contacts from the block at the various stages in the assembly process.
We have sought to provide an assembly which provides improved resistance to pullout of the connector contacts from the block forming a housing for the connector contacts and one which is particularly adapted to be applied to three bare pins of a header.
We have also sought to provide an assembly which is of much simpler construction and which may be simply and economically manufactured, all with improved reliability of locking of the contacts in the block.
Accordingly the present invention provides a block for housing an electrical contact comprising an electrically insulative housing having a longitudinal elongate contact-receiving passageway, a transverse pinreceiving hole and a transverse detentreceiving opening to prevent removal of a contact from the passageway, the detent including a locking lip adapted to project into the passageway to lock the cap to the housing.
In a preferred embodiment, the block has three longitudinal passageways adapted to receive three connector contacts and a transverse pin-receiving hole and an opposed detent-receiving opening communicating with each passageway The cap, which is preferably moulded integrally with the block and hinged at one end to the block, carries three detents, in spaced relation to each other, each detent being adapted to project through a detent-receiving eq eq : 1568,622 2 i opening on closing of the cap At least one of the detents includes an integral locking lip and is adapted to flex on passing through its respective opening and then spring backt whereby the locking-lip engages, the block in the -passageway aid locks the cap to’the’ block In one’ embodiment, the two outward detents carry lateral locking lips In another embodiment, all three detents indlude locking lips which extend across the contact-receiving passageways to lock the cap to the block.
The detents preferably provide rearward abutments to, prevent pullout -of – the connector contacts from the block and furthercooperate with forward abutments in the passageways to align receptacles of the contacts with the-pin-receiving openings and securely lock the-contacts in position ini, the block’ ‘ ‘ The contact of the assembly may be of known design and include a ferrule adapted to connect the contact to a lead-wire and-a receptacle constituted by a bottom ‘wal having a pin-receiving hole in’it and two side walls projecting perpendicularly from the bottom wall, the side walls being aligned on either side of-the hole ‘ The hole is preferably rectangular; The smaller dimension of the hole and spacing of the side walls is a few -thousandths of -an’ inch smaller than the diaimeter of the pin which the receptacle is designed to receive so that there is a press fit connection between the pin and the contact: The side walls are planar and’ lie parallel-to each other so that it is possible for the connector coitact to rock back and forth with respect to the pin to which it is applied without any stress on the metal whatsoever which would tend to plastically deformi it:
Embodiments of the invention will now be further described by way of example with,reference to the accompanying drawings, in which:
Fig 1 is a perspective view partly in section showing an assembly according to one embodiment of-the present invention; Fig 22 is a cross-sectional’ view through one passageway of the assembly shown in Fig 1 illustrating the connector contact locked in the block; Fig 3 is an end view of the assembly shown in Fig 1 illustrating the assembly as applied to a header; Fig 4 is a plan view of the assemrbly shown in Fig 1; Fig 5 is a perspective view partly broken and partly in section of another embodiment of the-present inv ention; and -_Fig 6 is a view taken along line 6-6 of With the cap locked in’place on the ” e,’:assembly illustrateda at 10 is adapted a glass-to-metal seal or header 12, the header being mounted on a hermetically sealed casing for a motor compressor unit The assembly inciudes a block 1 ‘4 and three contacts 15, each having a lead wire 16 70 attached t 6 it = Each contact includes a ‘ shank 18 having a w Vire gripping ferrule 19 having-an insulation gripping portion 20-and a bare wire gripping:-portion: 21 At the ‘ opposite end of the shank 18 is the recep 75 tacle 22 which includes a bottom wall’ 23 and two upwardly projecting side walls 24.
A rectangular hole 25 is formed in the bottom wa Il 23 The hole has a transverse dimension equal to the distance between the 80 side walls 24 and a longitudinal dimension substantially greater than the transverse dimension ‘-The transverse dimension of the hole 25 and the ‘distance between the side’walls 24 is’slightly less than the diam 85 eter of the pins II onto which the contact is pressed ‘For example, the one widely used pin size is 0:090 inch and the hole is dimiensioned 0,083 ‘/0087 “, -being approximately O ‘005 inch less than the diameter of 90 the pin so as to require a press fit when the contact is applied to the pin The block 14 in which the contacts are mounted is an integral unit having three longitudinal passageways 26 Preferably 95 the block is integrally moulded of a hard insulative plastics, although the particular material used is a matter of choice The outward passageways are identical to each other and are identical to the -centre pas 100 sageway except’ that the centre passageway is:displaced rearwardly of the assembly to permit the pin-receiving clips to be spaced equiangularly, thereby creating a rearward extension 28 of the block 14 Each pas 105 sageway 26 has a bottom wall 30, side walls 31 and, a top wall 32 The bottom wall 30 has a Circular hole 34 transverse to each longitudinal passageway 26 extending from one outer surface of the block 14 to-each 110 passageway 26 through which the pin: 11 passes to be received by the clip 15 The top wall 32 has a T-shaped opening 36 having, front and rear walls 38 and 39, respectively The opening 36 likewise ex 115 tends transverse to, each longitudinal passageway 26 from the opposite outer surface of the block 14 At the-forward end of the block 14 is a cap 40 The cap 40 is attached to the block 120 14-by a pair of integrally moulded hinges 42 at the outer edges thereof and is adapted to swing about-the hinges 42 (in the direction of the arrow in Fig I) and seat in a recess 44 in’the block, 14 The recess 44 in 125 the block may be chamfered as at 46 to facilitate this seating The cap 40-carries three detents 48 spaced one from -another so as to p’roject through the equiangularly 1 1 1 the dap 4:s seated nthe,’reces 44 ‘-Sine the block 14: has a:Rearwand exterisi & 28, the-‘cap 40 likewise includes an extension 50 irrying one of -the detents 48 -: ” ” ” -t -The cap 4)’ further includes thi-e bbloks 54, in spaced relation to the deteihts::’48 which are positioned’ such -that’ theftr ends 56 engage: the front: Walls: 38 of: the detbntyei vtig openin’ g 36-whenm the cap’ 40 ‘is seled and locked: ‘Each of the: detehts 48 tides a’ lbckint’g lip 58 adapted to engoge the-topwiall 32 of thei passageway 26 to lo’ck the eap 40:on the -brck 14 in the’recess’44 With the buter s’tl’f:ee thereof ‘being flush 1 S With:t A::outet:su’rfice of-the block A _i’0 e Tio:s pr Tovidod at ‘the base’of each detetint betweeilnthe detent’ 48 ‘and: block 54 $} permit the detent-to flex inwi;ardly as it passes through the detent-receiving: opening 36 to permit passing: of the’16 ocking -lip 58 therethrough When the lip 58 passes through the opening 36 the resiliency of the knatetial forming -the deteht springs the dtent rearwardly’ ad the locking lip 58 thereby engages the block 14 in the’passageway 26 to lock the cap-40 on the block 14.
The engagement of the wall 56 of the cap block 54 with the’ front wall 38 of:the letent-receiving ‘opening 36 provides the i O resisting force to the’flexing force -‘on the dletent 48 as’ it ‘passes through the’ opening 36 thereby removing: any forces on the hliiges 42 or cap 40 which ‘might cause flexing or distortion of those elements The block:’54 further resist sliding movement of the cap 40 ‘in:a direction that would release :the detents The detent 48 is rounded at its forward -end to facilitate its passage through the opening 36.
4 ‘ “‘In assembling the connector ecntacts 15 in’ the block 14 to form the assembly 10, each of three contacts’with lead wires attached is inserted in the longitudinal’ passageway 26 up against forward abutment’ 52 in the passageway-26 so disposed that the hole 25 in the contact 15 is aligned with the hole 34 in the block 14; The cap 40 is then ung about its hinges 42 and the detents 48 are forced thtough the detent-receiving Ad openings:36 On passing through the openings 36 X ‘the’ detents flex inwardly and, once through, spring back into locking engagement -in the passageways 26 The -detent 48 projecting into the passageway 26 A provides a rearward abutment adjacent the :ear of the contact receptacle 22 which cooperates with the:forward abutment 52 ‘in the passageway to maintain alignment of’the pin-receivin’g ‘he -25 ‘ in the r’eceptacle ’22 0 ‘:witti the pin-reteqiihg hole 34 in the block 1 t 4 ?The width’ of the detent 48 is greater -thail the distance-,b’etween the-outer surfaces t-f:teredeptaee side-walls 24, and thus the deteht: extends ae-o O the receptacle and 65:aevtnls -‘ttarwa# Cpulloiit of ‘the: contact.

When the contacts are in place, the assembly is ready for mounting onto the three pins 11 of a header 12 as shown in Fig 3.
When mounted on the header, the rearward 105 extension 28 of the block which forms the central longitudinal passageway rests upon the skirt 62 of the header 12 The forward end of the block has a foot 64 at each corner, the feet projecting-down into the 110 header and resting on the interior surface of the skirt 62 thereby maintaining the block level or flush with the edge of the skirt.
Referring now to Figs 5 and 6, there is shown another embodiment of the inven 115 tion which includes a block 70 having three longitudinal passageways 72 for receiving the connector contacts 15 Preferably the block is integrally moulded of a hard insulative plastics, although the particular ma 120 terial used is again a matter of choice.
The outward passageways are identical to each other and are identical to the centre passageway except that the centre passageway is again displaced rearwardly of the I 25 assembly to permit the pin-receiving con-tacts 15 to be spaced equiangularly, thereby creating a ‘rearward extension 74 of the block 70 Each passageway 72 has a bot tom Wall 76, side walls 78-:and a top wall 130 -56,622 1,568,622 The bottom wall 76 has a circular hole 82 transverse to each longitudinal passageway 72 extending from one outer surface of the cluster block 70 to each passageway 72 through which the pin 11 passes to be received by the contact 15 The top wall 80 has a rectangular detent-receiving opening 84 The openings 84 likewise extend transversely to each longitudinal passageway 72 from the opposite outer surface of the block 70.
At the forward end of the block 70 is a cap 86 The cap 86 is attached to the block by means of an integrally moulded hinge 88 extending across its width and is adapted to swing about the hinge 88 (in the direction of the arrow in Fig 5) and seat in a recess 90 in the block 70 The cap 86 carries three detents 92 spaced one from another so as to project through the equiangularly disposed detent-receiving openings 84 when the cap 86 is seated in the recess 90 Since the block 70 has a rearward extension 74, the cap 86 likewise includes an extension 94 carrying one of the detents 92.
Each of the two outward detents 92 includes a locking lip 96 adapted to engage the top wall 80 of its respective passageway 72 along an outward edge to lock the cap 86 on the block 70 in the recess 90 with the outer surface thereof being flush with the outer surface of the block and with all of the detents 92 extending into the passageways 72 (Fig 6) In this embodiment, locking lips are formed on only two of the detents 92, this being sufficient to lock the cap on the block Moreover, the locking lips now project laterally of the cap 86 such that when the cap is locked to the block the lips 96 extend along a portion of the length of the passageway, i e, in a direction parallel to the direction of the longitudinal passageways 72, rather than across or transverse to the longitudinal passageways as in the embodiment shown in Figs 1 to 4 The detents 92 are again rounded to facilitate passing of the locking lips 96 through the openings 84 with the two outward detents 92 flexing inwardly as they pass through the detent-receiving openings 84 to permit passing of the locking lips 96 therethrough When the lips 96 pass through the openings 84, the resiliency of the material forming the detents springs the detents outwardly and the locking lips 96 thereby engage the block 70 in the passageways 72 to lock the cap 86 on the block 70.
The embodiment shown in Figs 5 and 6 is particularly advantageous in that it permits greater tolerances in the manufacture of the block That is, in the embodiment shown in Figs 1 to 4 it is necessary to accurately control certain manufacturing tolerances, the critical dimensions being the distance from the hinges 42 to the three detents 48 as well as the disposition of the detent-receiving openings and of the blocks 54 For example, should the extension 50 carrying the centre detent 48 be formed 70 slightly too long, or too-short, the detent 48 and block 54 will not be aligned with its detent-receiving opening when the cap is swung onto the block thus preventing any of the detents from entering the passage 75 ways and preventing locking of the cap to the block In the embodiment shown in Figs 5 and 6, the detent-receiving openings can be oversized thereby minimizing the criticality of the longitudinal dimension 80 In this embodiment, it is necessary only to control the tolerances between the outward detents and detent-receiving openings, which is the shorter transverse direction and is easier to accomplish from a manu 85 facturing standpoint Moreover, it will be noted that in this embodiment, the blocks 54 have been eliminated since the outward detents 96 flex inwardly on passing through the openings 84; and, consequently, there 90 are no forces on the hinge 88 Further, since the cap 86 nests in the recess 90, as shown most clearly in Fig 6, movement of the cap in a direction that would release the locking lips 96 is prevented 95 In assembling the connector contacts 15 in the block 70 to form the assembly in this embodiment, each of three contacts with lead wires attached is inserted in the longitudinal passageway 72 up against a forward 100 abutment 98 in the passageway 72 so disposed that the hole 25 in the contact 15 is aligned with the hole -82 in the block 70.
The cap 86 is then swung about its hinge -88 and the outward detents 92 are forced 105 through the detent-receiving openings 84.
The centre detent not having a locking lip is merely projected through its openings on swinging of the cap into place on the block.
On passing through the openings 84, the 110 detents flex inwardly and, once through, spring back outwardly into locking engagement in the passageways 72 The detents 92 projecting into the passageways 72 provide rearward abutments adjacent the rear 115 of the contact receptacles 22 which cooperates with the forward abutments 98 in the passageways to maintain alignment of the pin-receiving holes 25 in the receptacles 22 with the pin-receiving holes 82 in the 120 block 70 The width of the detents 92 is greater than the distance between the outer surfaces of the receptacle side walls 24, and thus the detents extend across the receptacles and prevent rearward pullout of the 125 contacts The forward abutments likewise prevent forward movement of the contacts.
However, should it be desired to remove the contacts from the block, for example, for reworking of the contacts, the cap can 130 1,568,622 be unlocked by inserting a tool to flex the outward detents inwardly until the locking lips are disengaged at which point the cap can be swung off the block The contacts may then be simply slid out of the block without being subjected to any deforming force whatsoever.
When the contacts are in place, the assembly is ready for mounting onto the three pins 11 of a header 12 in the same manner as described above in relation to Fig 3.
Although the invention has been described in terms of certain preferred embodiments, it will be recognized that other forms may be adopted by those skilled in the art within the scope of the invention.
