Abstract
The electrical connector block comprises an insulating body and a plurality of conductor terminals mounted in it of which at least one is a protective conductor terminal. It is provided with an additional contacting member which passes through the base of the insulating body facing a connector block support and has at least one exterior plug which can directly make contact in a socket in the connector block support. The protective conductor plug can be mounted in the connector block during manufacture of the connector block or also subsequently to making the connector block without having to dismantle it. The structure and positioning of the protective conductor plug or plugs allows an easy automatic connection to the protective conductor by plugging the conector block into the connector block support.

Complete Specification for the invention entitled: eemoIECTIZN ett A~TACHNT crar01 A34S, V” CTI ArrPArATUS The following statement is 4 full description of this invention, ihcluding the beat method of performing it knovm to me:tt0 CONNECTOR BLOCK FOR ELECTRICAL DEVICES Field of the Invention Our present invention relates to an electrical connector block or terminal block for electrical devices, and more particularly to a connector block for lights, stoves or ovens, machinery, washing machines and the like.
Background of the Invention An electrical connector block can comprise an insulating body and a plurality of conductor terminals mounted in the body of which at least one is a protective conductor terminal which is provided with an additional contacting member which can make electrical contact in or with the coninector block support, e.g.
Sfor grounding a conductor affixed to tlhe block.
:In one known electrical connector block the ground is go4 t* usually made by connecting a special cable (grounding cable) to C the pole of the connector block to which the protective conductor of the power supply cable is connected. The other jend o f this special cable is attached to the electrically 02V~ conducting portion of the device to be groundedl particularly by a terminal screw. This is bothersome and inconvenient.
An electrical row terminal block for a switching device is described in German Patent Document DE-tJ/76 13 429 in which a protective conductor connector body is positioned in a plane displaced with respect to the conductor connector body. The protective conductor plane is positioned substantially in the plane of the connector block support which is a supporting Ala 400 A -77″ 1W PIZ

rail. The supporting rail acts simultaneously as a protective conductor rail and the protective conductor connector body is connectable electrically with the supporting rail. This connection is effected by a special clamping mechanism which operates with a separate screw. This clamping mechanism is comparatively expensive and makes the assembly and disassembly of the connector block difficult. Furthermore, the fabrication of the protective conductor terminal is made difficult by additional required manual work.
Objects of the Invention It is an object of our invention to provide an improved connector block or terminal block for electrical devices which overcomes the aforedescribed and other drawbacks of the prior art.

To guarantee a particularly reliable contact the plug is advantageously provided with sharp edges to penetrate an insulating layer covering the generally sheet metal connector block support. Thus preparing the connector block support by abrading away the lacquer coating for a reliable contact is dispensed with when our invention is used. The sharpo edges of the plug can also be provided on outwardl’y extending integral resilient prongs. At the same time a tolerance compensating fit of the plug in its socket is guaranteed in an easy way.

This has the particular advantage that the connector block can be equipped subsequentl-y with the -protective conductor terminal plug, according to our invention, when it is not provided in making or using the connector block. All that is necessary is that a wiall or base of the insulating body be provided with a-hole or holes or b~e struc-tured, so that a. hole or h~oles can subse.quently be z4Iide~ or:example ,by .pushing through, ,and tha-t the &dit an~ 10 contact~ing:1member be installed.

S II L 1 with resilient contacting legs 19′ and 19”. The clip 18 acts as a support and holder for the contacting spring 19.
The resilient legs 19′ and 19″ of the contacting spring 19 form screwless connecting terminals between their front edges and the opposing surfaces of the clip 18. The connecting terminal formed by the resilient contacting leg il’ may be opened with the help of the key 20 on the outside of the housing according to the user’s wishes in order to remove the conductor held therein. When the key is pressed down, the conductor is locked to the connector 18/19.
For plugging into connector block support 21 the connector body 11 has two resilient locking feet 22 on its base or wall lla which can be plugged into the sockets 23 of the connector block support 21. The connector block or connector terminal 10 is then held fixed on the connector block support 21 after being plugged in by the reexpanding insulating locking feet 22 which were compressed on insertion.
The above described structure for the connector block 10 is known and used in earlier models. The structure and arrangement of an additional contacting member 24 with an exterior plug 25 for the protective conductor terminal 26 are in contrast new.
In the embodiment according to FIG. 3 the additional contacting member 24 is formed from a small metal strip which in the most approximate sense is W-shaped as seen in FIG. 1.
The plug 25 is made by bending back the metal strip approximately 1800.. On both sides of thi~ bent -9-

back metal strip there are sometimes two, but here four, i .flexible prongs 27 bent outwards. Their edges 28 are sharp and/or sharpened.
The plug 25 is designed to be inserted in an additional socket 29 of the connector block support 21. In Sthis embodiment the socket 29 is of the same type and size as the sockets 23 for the resilient locking feet 22 of the i :insulating body 11. The above mentioned sharp edges 28 of the plug 25 contact the boundary of the socket 29 on insertion and 10 remove the lacquer or oxide coating there by abrasion in order to make an effective electrical contact with the connector block support 21.
As is easily conceived, this contact is made automatically and at the same time as the mounting of the connector block 10 on the connector block support 21. As the connector block 10 is plugged in, the additional contacting member 24 is also connected with the connector block support 21.
In this first embodiment the additional contacting member 24 has a special structure and is fitted from’the outside of the insulating body 11. For this purpose, the base Slib of the insulating body 11 has two holes 30 and 31 through it for receiving two connecting legs 32 and 33 of the additional contacting member 24. The two holes 31 and 32 are thus in the side of the insulating body 11 facing the S connector block support 21.
The connecting leg :2 is formed with an Sapproximately right angle bend and is easily wave like or 1 1 -I 1 1 1 7580MR.
S-shaped and at one end of it there is an insert portion 34 for bracing on the inner surface of the insulai-;g body base lib next to the hole 30. The second connecting leg 33 is bent so that it is bent back into a U-shape resilient plug-in segment 35 which can be engaged in the other hole 31.
The mounting occurs so that the insert portion 34 of the connecting leg 32 is inserted in the hole 30 while the i t? additional contacting member 24 can be swung in a t clockwise sense in reference to FIG. 3 until the plug-in segment 35 reaches the illustrated position.
In this position, the additional contacting member tt S 24 is held only on the base llb of the insulating body 11 so that it is guaranteed that an electrical contact with the C connector body 18/19 occurs. One such contact can be made by a simple contact of the additional contacting member 24 -in-the S° region where it engages with the surfaces and edges of the connector body 18/19.
In the embodiment according to FIG. 3 a direct connection is possible with the connector body 18/19, although the contacting member 24 is mounted from the outside of the insulating body 11. Thus the bent or folded resilient plug-in segment 35 plugged into the recess or receptacle 36 in the contacting spring 19 simultaneously is provided for contact with a bent up tongue 37 of the clip 18. The other connecting j: ,i 25 leg 32 opposite the connecting leg 33 because of spring tension presses with the front edge of its free end insert portion 34 against a protruding piece 38 bent out from the clip 18. The additional contacting member 24 is also plugged -ii- 1 directly by connecting legs 33 and 32 into the connector body 18/19 so that here the holes 30 and 31 are not needed to hold the additional contacting member 24.
Since it is desired to provide the known connector block with a connector body arrangement with an additional protective contacting member 24 the holes 30 and 31 are placed in the base llb of the insulation body 11 only near the protective conductor connector body 11 only near the protective conductor connector body cavity 17. In our new insulating bodies 11 these holes 30 and 31 can be provided by punch-out openings, for example by weakening portions of the base lib of the insulating body 11, which are then punched out when the connector block 10 is to be provided with the additional S contacting member 24.
r: 6 FIG. 3A shows an embodiment generally similar to FIG. 3 but wherein the plug 25′ with its barbs 27′ is formed unitarily *with the contact 19a’ corresponding to the contact 19. The ns strip of the contact 19a’ is passed out through the opening 31; bent at 33; formed into the plug 25′ and bent and filled at 32′ in the opening 0 The embodiments shown in FIGS. 4 and 6 also have the 06 So** mentioned and additional advantages. Insofar as these embodiments are similar to or identical to that according to FIG. 3 their description is not repeated here. Parts of these -i embodiments, which are similar to or the same as the embodiment I ,A of FIG. 3 are numbered correspondingly.
SIn the embodiments of FIGS. 4 and 6 the additional contacting member 24 is not formed by bending bdt by punching -12- 1 .ih ^Si t *ll 1 C i I out’a flat but unshaped piece of sheet: metal or plate. In the embodiment according to FIG. 4 the single piece contacting member 24 can be thought to comprise an anchoring section 47 and a plug 25 formed from the individual sections 39 to 41.
The leg section 41 connected to the bend section 40 opposite the connecting section 39 is in contrast to the connecting section 39 somewhat flexible so as to be tolerance compensating. The substantially U-shape plug 25 engages in a coionector block support socket 29 similar to the first embodiment according to FIGS. 1 and 3. The edges 46 of the connecting section 39 and the flexible leg section 41 are sharpened for removal of a lacquer or oxide coating on the bounding surfaces 29a of the corresponding socket 29.
The plug 125 shown in FIG. 4 is also mounted from the outside and is pushed into a single hole 30 circumferentially fitting the anchoring section 47 until the pushed in bounding shoulder 43 is put in a corresponding fitting groove 44 of the insulating body 11.
The contacting member 124 is held In such a way that at least one of each connecting legs 32 and 33 cooperate or act ‘,..together with the legs of the contacting spring 19 and the clip This occurs because the connecting leg 32 is forced in the smaller clamping slot 42 of the clip 18 and is hold clamped in Sit. The second connecting leg 33 can of course analogously be o j2 4, held in another section of a contacting spring or clip, but Shere braces itself- on the laft edge of the tongue 37 as seen in PIG* S locked therein by its ‘shape and site or force-locked.
The connecting leg 32 is clamped on the edges of the cut out 42 13-
