The invention relates to electrical connection terminals as described in application A 29 234 VIIId / 21c.

In the earlier application mentioned there is an electrical one Connection between two electrical connection terminals The connecting terminals are connected with electrical conductors. They overlap and lie in one Channel. Each connector faces you forward extending part, which is bent back at the tip at an acute angle and thus forms a spring-shaped tongue, which is also in the canal. The outer sides of the resilient tongues of the connecting clamp lie against one another and, thus keep a resilient contact due to their location

upright in the canal.

.An electrical connection terminal according to the invention consists of a flat base on which means are provided to connect the same with an electrical conductor connect to. Furthermore, a resilient tongue is provided, which follows at an acute angle from the flat green part is bent back and so turned outwards Has surface which is located at a certain distance from the base part. This area is used for manufacturing an electrical contact with a corresponding surface of a second, similarly designed connecting terminal. Locking means are provided between the base part and the tongue, which prevent the deflection movement in the event of a bending load limit the tongue in the direction of the flat base. ;

Conveniently, side flanges are provided on the base part on its sides near the tongue, which after have inwardly curved parts which extend between the tongue and the base part. The flanges extend in the longitudinal direction of the base part along the opposite one Edges of the same. The bent parts of the flanges extend roughly the length of the resilient ones Tongue.

The invention will now be explained below with reference to the accompanying drawings, which illustrate exemplary embodiments. It means:

Fig. 1 is a plan view of a connecting terminal which attached to an electrical conductor;

Fig. 2 is a side view of the connecting clamp of Fig. 1j

3 shows a sectional drawing of two nested housing parts which contain cooperating connecting terminals according to FIGS. 1 and 2; . -

Fig. 4 is a cross-sectional view taken along line 4-4 in Fig. 1; on an enlarged scale;

Fig. 5 is an enlarged view of the end portion of the connecting clip according to Fig. 2.

The connecting terminal shown in Figures 1, 2 and -4 consists of an elongated flat base part 4, the one has approximately rectangular shape and has clamp parts 6 and IO at its rear end, through which it is connected to the Isolation, or the core of an isolated electrical conductor connected is. The front end of the base 4 has an extension which, as can be seen at point 12, at an acute angle with respect to the base part 4 to the rear is curved, and so one sloping backwards and upwards resilient tongue 14 (Fig. 2) forms. At its opposite edges on both sides of the tongue 14 has the base part 4 upright flanges 20 which extend over the length of the base part 4 and on their rear ends into the side parts of the pressure rocker 10 provided for the core of the electrical conductor

pass over. The front parts of the pool 20 are along their upper edges bent inwards. So they form eyelets 22, which are almost over under the resilient tongue 14 their entire length extend. From Pig. 4 it can be seen that the inwardly curved parts 22 underneath the space bridge the resilient tongue 14 by and large. From Pig. 1 it can be seen that the front edges of the after inwardly curved parts inclined inwards and backwards are.

Under the resilient tongue 14, another tongue 16 is cut out of the base part 4, the tongue goes out of the Base part 4 protrudes at its front end and extends from there downwards and backwards. The side flanges 20 have at their rear ends corresponding upwardly projecting paddles or shoulder parts 18 as that from Pig. 2 can be seen, they lie to the rear following the resilient tongue 14 '. Connecting skis after Pig. 1, 2 and 4 can be mounted in one housing will, by and large, be the ones in Pig. 3 has shown porm. It consists of insulating material on mating parts. In each part there are several continuous cavities into which the connecting terminals are inserted will. Each cavity has a rear portion 26, the de ferrule parts 6 and 10 of the connecting terminal receives, and a front part 30, which the resilient .Zunge 14 and the front part of the base part 4 receives. A stop member 28 separates the parts 26 and 30 of the cavity

and has a central opening through rich ,, the front cable can be inserted AEAC Verbindungskiemme. The forward movement during insertion is through the stop of the protruding shoulders 18 on one side of the ■ stop. teüßs 28 limited. The fact that the tongue 16 cooperates with the stop part 28 on the other side thereof prevents the connecting terminal from being withdrawn. The interaction of the housing parts in the Mg. ' 5 brings the corresponding contact surfaces of the resilient tongues 14 of the corresponding connecting terminals into contact. In this way, the surfaces are effectively pressed against one another as contacts when the corresponding housing parts are pushed into one another. Thus, in the position shown in FIG. 3, the resilient tongues are pressed elastically downward or bent around part 12. This creates a contact pressure between the mutually corresponding contact surface parts. It is caused by the fact that the housing is designed so that the resilient tongues cannot evade this pressure. It should be noted that the housing parts serve to prevent movement of the connecting terminals against one another.

The inwardly bent ropes 22 limit movement the resilient tongue 14 as a result of the bending pressure, so the tongue 14 cannot move beyond a limit position, which is determined in that it rests on the parts 22 in the manner shown in FIG. Appropriately if <$ ß height of the parts 22 above the base part 4 is chosen so,

that when operating through. Assembling the terminals in the in Pig. 3 no overstressing of the resilient tongue 14 and the bending point 12 occurs.

The "connector" is in this way against stress the tongue 14 is protected during operation in the housing shown. Likewise, it is against stress Protected during handling prior to assembly in the housing.
