description

The innovation concerns an electrical connector be ^ standing from a housing with a base part from which two longitudinal walls and two transverse walls extend perpendicularly, each transverse wall comprising a contactor, whose cross-section widens inwards from the outer surface of the corresponding transverse wall, and wherein the slot extends perpendicular to the base part and is open at least at one end; from a Number of contact elements, at least a part of which extends through a space that is inside of the connector housing is limited by the walls and which is open on one side to the connector counterpart

and with a fastening device which consists of fastening lugs, the shape of which is adapted to the desired fastening conditions * each fastening lug has at least one flat surface from which an edge extends outwards, * which widens outwards from the surface, wherein the shape of this edge corresponds to the shape of the slot in the transverse walls and wherein the edge is intended to enter the slot of the transverse wall from an open one

To be pushed in at the end.

An electrical connector of this type is known. The means for attaching this known connector comprises not just a fastening strap, the shape of which is adapted to the desired fastening conditions, but

also a connection plate, which after the insertion of the Edge of the fastening tab into the slot in a bulkhead is connected to a part protruding from the fastening tab so that the edge comes out of the slot can not solve.

The disadvantage of these known connectors is that an additional connection plate must be used.

The innovation is therefore based on the tasks j one
to create electrical plug that gets by with fewer components and solves in a very simple manner the problem of attaching a fastening strap to a certain transverse wall of an electrical plug

This object is achieved with a connector of the type mentioned in that the fastening tab and the transverse wall comprise a connecting device, which consists of a resilient Kuppslsment, which with the Fastening strap is connected and consists of a stop lug, which is attached to the transverse wall or vice versa, and which is designed so that during the insertion of the plate a fastening tab in the slot of a certain transverse wall the resilient

Coupling element is gradually deformed by the stop nose and then snaps behind this nose, so that the
Fastening strap is attached to the bulkhead.

The stop lug is preferably of a hook-shaped end of a second coupling element, which
either with the bulkhead or the fastening strap
connected is formed.

The innovation is described below with reference to the drawings, in which identical parts have the same reference numerals are provided, further explained and described.

Figures 3j ^ and 5

Fig. 13 is a top view, a front view and a side view, respectively of Figs g fastening sash.

In FIG. 1, the electrical connector is designated as a whole by the reference number 10. The connector includes a Base partj which is not shown in the figure and longitudinal walls 12 and 1 * J extending perpendicularly thereon as well as two transverse walls 13 and 15, which together delimit a space in the plug, which in FIG. 2 is open at the top is. The contacts 16 are located in this space. Such a construction is generally known.

In FIG. 1, the plug is connected to a ribbon cable 11. However, the innovation is not limited to but also relates, for example, to connectors intended for attachment to printed circuit boards or plugs with coiled wire contacts, etc.

In Figure 1, two fastening tabs 17 and 18 are shown, which, as indicated in Figure 1, on the

electrical connector 10 can be attached. To 25

for this purpose the transverse walls 13 and 15 each comprise a slit which is dovetailed in cross section. Each fastening tab 17 and 18 comprises a plate section, which is also dovetailed in cross section

is shaped and is intended to be inserted into the slot of a 30th

corresponding transverse wall 13 and 15 to be used.

Figure 2 shows a view of one of the transverse walls 13 or 15. The slot 20 within the wall is of

the edges 21 and 22 limited. Within this 35th

A stop lug 23 is attached to the slot 20 and extends away from the rear wall of the slot 20. The thickness of the nose 23 corresponds approximately to the thickness of the

Page marks 21 and 22.

ι The fastening tab is shown in Figures 3, ^ and S

shown in detail. It includes the mounting base 31 with a passage 33 and the plate 30, which extends from one side of the mounting base 31 away. As can be seen more clearly with reference to FIG can be seen, the plate 30 has a cutout 32 in which a resilient coupling element 3 * J - 'sits, weicnes on eggs and canoe; uets Huaacnnlubo o <c

is fixed. It is clear from the figures that j | that the resilient coupling element with the stop

i <nose cooperates so that the fastening tab

is fixed when inserting the plate 30 into the slot 20 after a certain distance on the electrical connector. During the insertion movement, the resilient coupling element 3 ¹ I ₁ is deformed as soon as it reaches the stop lug 23. This is done through the left

p-facing run-up edge of the stop lug 23 (as in

* ² ^ Figure 2 shown). At the end of the insertion movement> the resilient coupling element snaps under the

impact lug 23 so that the fastening tab is firmly connected to the plug.
