PATENT SPECIFICATION
( 21) Application No 22118/77 ( 22) Filed 25 May 1977 ( 31) Convention Application No 689 976 ( 32) Filed 26 May 1976 in ( 33) United States of America (US) ( 44) Complete Specification published 11 June 1980 ( 51) INT CL 3 H Oi R 13/02, 23/10 ( 52) Index at acceptance H 2 E 11 2 C 2 F 3 A 13 3 A 4 D 3 A 53 B 4 A 3 B 63 C 2 C 3 C 2 D 3 C 2 E 3 D 3 3 E 22 3 E 27 3 E 6 5 7 E 2 C ( 11) 1569379 ( 54) ELECTRICAL CONNECTOR SYSTEM ( 71) We, MINNESOTA MINING AND MANUFACTURING COMPANY, a corporation organised and existing under the laws of the State of Delaware, United States of America, of 3 M Center, Saint Paul, Minnesota 55101, United States of America, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the
following statement: –
The present invention relates to an electrical connector particularly adapted for use on a perforated circuit board.
Electronic circuitry today typically makes use of integrated circuit wafers or chips mounted on standardized interconnection packages which have protruding therefrom a number of electrical connecting leads in a standardized pattern for connection into larger circuit assemblies The connection of the integrated circuit packages with other electronic assemblies has typically been by direct soldering, or by inserting the electrical leads of the integrated circuit package into receptacles in an insulating housing, the connection being continued through the housing to the circuit board Such integrated circuit connectors are disclosed in U S Patent Nos.
3,602,874; 3,624,586; 3,673,551; 3,673,543; 3,683,317; 3,710,299; and 3,883,207.
A contact element frequently used in such connectors comprises a narrow flat plate of relatively resilient and electrically conductive material which is centrally slotted to receive and strip the electrical insulation from electrical wires, said slot defining a pair of spring legs When a wire is pushed into the slot the legs are slightly deformed outwardly and in attempting to spring back to their original positions they apply pressure on the wire, thus maintaining good electrical contact Such legs may be thought to have a reserve of spring compression, hence the contacts are commonly entitled ‘spring compression reserve wire contact elements’, and are so described herein Likewise the slot of the contact element is described herein as a ‘spring compression reserve wire contact slot’.
When prototyping electronic circuits utilizing integrated circuit packages, it is obviously desirable to have the wiring and components in the position that they will occupy in the commercially produced circuit, both in terms of size and location Moreover, it is highly.
desirable that not only the integrated circuit package be readily removable and replaceable, but that the electrical interconnection wiring also be readily changeable Such versatility has not previously been available in electronic circuitry prototyping.
The present invention provides an electrical connector for use with a perforated circuit board, and comprises a connector body having an insulating housing defining a plurality of cavities therein and a pair of opposite faces, the cavities intersecting the faces of said housing so as to form on one face an array of spaced apertures aligned in use with the perforations in a said circuit board, and a plurality of contact elements retained in said housing, one within each cavity therein, wherein each said contact element in said insulating housing is formed of a metal strip and has adjacent oppositely directed resilient jaws, one set of jaws being aligned with an opening at said one face of said housing and the oppositely directed set of jaws being aligned with the aperture’s opening at the opposite face of said housing, and a contact strip comprising an insulating contact retainer with a plurality of contact apertures therethrough, the aperture openings at one face of said contact strip being spaced to align with said aperture at said one face of said connector body housing, and a plurality of spring compression reserve wire contact elements as defined herein, one in each of said contact apertures, each said contact element having a spring compression reserve wire slot accessible at the face of said contact retainer opposite said one face thereof and having a tail extending from said one face of said contact retainer to fit in use through a perforation in a said circuit board and an 0 m dsh 1,569,379 aligned aperture in said one face of said connector body housing into the aligned resilient jaws of a spring contact element.
One set of jaws of a spring contact element in the connector can receive an electrical lead of an integrated circuit package, while the oppositely directed set of jaws receives the tail of the spring compression reserve wire contact element Electrical connection is thereby made from the integrated circuit package through the spring contact element and the spring compression reserve wire contact element to one or more wires in the wire contact slot of the contact element The electrical leads or tails of the integrated circuit package are readily inserted and removed from the spring contact elements to permit ready removal and replacement of the integrated circuit package, and the spring compression reserve wire contact elements permit easy wiring and re-wiring of the circuit.
In the drawing Figure 1 is an exploded perspective view of the components of an electrical connector system in accordance with the present invention in use with an integrated circuit package and a perforated printed circuit board; Figure 2 is a cross-sectional view illustrating one complete connection of the electrical connector system of Figure 1; and Figure 3 is a cross-sectional view taken generally along line 3-3 of Figure 2.
The electrical connector system of the present invention comprises a connector body and a contact strip 12 The connector body 10 and the contact strip 12 are construed for use with a standard perforated circuit board 14 having regularly spaced perforations 15 and a standard integrated circuit package 16 having a plurality of electrical leads 17 The standard spacing of the perforations 15 in the circuit board 14 is the same as the standard longitudinal spacing between electrical leads 17 of the integrated circuit package 16, as is illustrated.
The connector body 10 comprises an insulating housing 19 and a plurality of spring contact elements 21 retained in the housing 19 The insulating housing has a plurality of apertures therethrough, the aperture openings 23 at one face of the housing 19 are spaced to align with perforations 15 in the printed circuit board 14 The aperture openings 25 at the opposite face of the housing are longitudinallv aligned with the aperture openings 23, but they are slightly off-set width-wise of the housing, as can be seen in Figure 2.
One spring contact element 21 is retained i R each aperture through the housing 19, the apertures being enlarged within the housing to receive and retain the spring contact elements 21 in position Each spring contact element 21 is formed of a resilient metal strip into a generally S-shape to define adjacent, oppositely directed jaws 26 and 27 Each spring contact element 21 is positioned in the 65 housing aperture with one set of jaws 26 aligned with the aperture opening 23 which is aligned with a perforation 15 in the printed circuit board 14, while the oppositely directed jaws 27 are aligned with the aperture opening 70 in the opposite face of the housing 19.
The contact strip 12 comprises an insulating contact retainer 29 and a plurality of spring compression reserve wire contact elements 31 as hereinbefore defined Two such 75 contact strips 12 are illustrated, one corresponding to each row of electrical leads 17 of the integrated circuit package 16.
The insulating contact retainer has a plurality of contact apertures 33 therethrough, the 80 illustrated apertures 33 extending straight through the contact retainer 29, and being longitudinally spaced to align with perforations 15 in the printed circuit board and the like aligned aperture openings 23 in the con 85 nector body housing 19.
One spring compression reserve wire contact element 31 is retained in each of the contact apertures 33 The contact elements 31 are generally planar, and each contact element is 90 formed with a projection 34 in a portion thereof within the contact retainer 29 to firmly retain the contact element 31 in the aperture 33 through the contact retainer 29.
Each contact element 31 is formed with a 95 spring compression reserve wire contact slot 36 accessible at one surface of the contact retainer 29 The slot 36 in each element contact 31 is coined to make it progressively narrower from the open end thereof to assure 100 effective electrical connection with two electrical conductors of the same diameter Each contact element 31 is formed with a tail 37 extending from the surface of the contact retainer 29 opposite the wire contact slot 36 105 Each contact tail 37 is sufficiently long to extend through a perforation 15 in the printed circuit board 14, through the aligned aperture opening 23 in the connector body housing 19 and into the aligned resilient jaws 26 of a 110 spring contact element 21.
The tail 37 of each wire contact element 31 is slit longitudinally, centrally of its length and width, and it is similarly deformed transversely out of its plane in opposite directions 115 along the sides of the slit to form oppositely directed leaf springs 39 and 40 The leaf springs 39 and 40 will deform to pass through a perforation 15, and will, when the contact retainer 29 rests on the upper surface of the 120 printed circuit board 14, engage the periphery of the perforation 15 at two points on the lower surface of the printed circuit board 14 to retain the contact strip 12 on the printed circuit board 14 (See Figure 3) 125 At its free end the tail 37 of each contact element 31 is formed with a protrusion 42 out of its plane The protrusion 42 passes through 1,569,379 the jaws 26 of the spring contact element 21 during assembly to firmly engage the inside of the jaws 26 to retain the connector body on the printed circuit board 14 with the spring contact element 21 electrically connected to the corresponding element 31 The width of the enlarged portion of a connector body aperture in which a spring contact element 21 is retained is dimensioned to restrict the movement of the ends of the spring contact element 21 The expansion of the resilient jaws 26 and 27 is thereby restricted so that when an integrated circuit electrical lead 17 is inserted into the jaws 27 there is not sufficient room for expansion of the jaws 26 to permit passage of the protrusion 42 at the end of the contact tail 37 The connector body 10 and contact strip 12 are thus firmly locked onto the printed circuit board 14 when an integrated circuit package 16 is in position on the connector body 10.
In use, a connector body 10 is positioned on one side of a printed circuit board 14 and a pair of contact strips 12 are positioned on the opposite surface of the printed circuit board with the wire contact tails 37 aligned with the perforations 15 and the corresponding aperture openings 23 in the connector body housing 19 The contact strips 12 are then moved inward to move the contact tails 37 through the perforations 15, through the aperture openings 23 in the connector body housing 19 and into the jaws 26 of the spring contact elements 21 An integrated circuit package 16 is then positioned adjacent the lower surface of the connector body 10 and its generally planar electrical leads 17 move through the aperture openings 25 in the connector body housing 19 and into the aligned jaws 27 of the spring contact elements 21 The desired electrical connections through the integrated circuit package 16 are then made by pressing electrical wires into the slots 36 of the spring compression reserve wire contact elements 31.
While only one integrated circuit package 16 and the components of the electrical connector system of the present invention necessary to make contact to it are shown, it will be understood that there generally will be a multiplicity of similar appearing assemblies utilized in prototyping a complete electronic circuit.
