The various figures will now be explained in detail. The same reference numerals identify the same parts. In Fig.l, a contact 10 is shown with a locking device according to a first embodiment of the invention. The contact 10 "is grundBätzlioh of a fork-shaped, with a different! Eil mating portion 12, from a body piece 14 and a rear part 16 for the locking device of the invention. The fork-shaped portion 12 is formed in correspondence with contacts such as sold under the trademark ¹¹ VARIOOlT "come into trade. In addition, this section is designed according to US Pat. No. 2,828,474. The overall contact 10, including its section 12, is flat and made of spring-hard phosphor bronze, copper or some other electrically conductive material 0.012 "thick, the material having the required balance of flexibility and strength. The section 12 is due to the slot The slot 18 is located in the middle of the section 12 in its longitudinal direction. This results in two contact legs 20, 22 which are spaced from one another as a result of the base seat 18. The outer edges of the contact loops 20, 22 are generally parallel to one another, until it reaches the tips 24. Then taper

909807 / 08U

Bioh the Auesenkanten the handle 20,22 about 8 soharf in the red to one another to the flattened tips 26. The contact surfaces taper towards each other, in order to obtain the inner edges 26 on the base seat 13.

As can be seen from FIG. 8, the inner edges are 28 beveled in such a way that flat contact surfaces 30 receives. I'm in contact with someone pairing up with other ropes Portion formed in the same manner fits in the perpendicular direction with respect to a contact Fig.l together, as in the US patent drifts 2,828,474 and 2,994,506 so that the beveled surfaces of the mating sections

Are in engagement with each other in such a way that a large electrical contact surface is formed. The distance between the inner edges 28 of the contact handles is slightly smaller as the dioke dee contact, eo that if a related Contact is brewed into engagement with the slot 18, the Contact legs 20,22 are somewhat pressed apart in order to to grab the associated contact with tension. These Tension is increased a little bit, that a bigger one Opening? 2 at the rear end of the sole plate 18 is available. The opening 32 has a hinge-like effect.

This makes the slot 18 somewhat narrower than the usual is possible. Will the two cooperating contact brought into their matching position, the legs 20, 22 become somewhat as a result of the above-mentioned eoharnier-like Effect spread apart, so that you get a smooth sliding movement between the pairs of contact legs, but there is still sufficient voltage to ensure good electrical contact.

It is clear that other .types of forked, mating Sections can be used. The eusanraen fitting Sections can be formed into a die, male, or other manner such as this is known. It is essential that the parts fit together sufficiently, with the thickness of the mating Section has the order of magnitude of 0.012 ". In addition, the material with such a thickness must be sufficiently resilient, with the rear part being of sufficient strength, as will be explained later.

The matching section with another section 12 also has a spike-shaped locking part 34.Serselbe protrudes from the section 12 to the rear and is also

has two approximately rectangular wings 48 that extend through • a bridging part 50 are connected. The second gripping means 46 has two approximately quadrangular wings SO, which are connected to one another by a bridging part 52. The bridging part 52 is located slightly above of the bridging part 50 or at another level. This is determined by level 54. The dreieofcigen Wings 48 are through the slots 56 of the wings 50 separated.

The use of the contact 10 in an insulating housing of the connector is shown in Fig.4. Two-way fastening of the conductor 58 of an external circuit with the contact 10, the insulation 60 becomes on the guide part removed from lead 58 so as to expose conductive piece 62. The conductive piece 62 is between the wings

The insulation housing 62 basically consists of a rear chamber & 4 »from a narrow neck part 66 and off an anterior chamber 68.

If the contact 10 with the conductor 58 from the rear Chamber 64 is pressed into the front chamber 68, the epiessfärmige locked 34 is first in the plane of the contact Busty neck when he goes through the similar neck part 66 passes through. As soon as the spit-shaped Spevrteil 54 of the narrow neck part 66 is released, it jumps back immediately to its original position, as shown Pig.4- emerges. The locking shoulder 42 is now more according to FIG arranged on the opposite side of the neck part 66 on the apse-shaped locking part 54. I) Ie locking shoulder 42 is then pushed down so as to obtain contact with a rope of the halo part 66 and thereby the blocking of contact with the external circuit 58 in the insulation housing 62 to complete.

It can thus be seen that the tedious work of fastening the conductor of an external circuit with a contact borrows can be completed before it is placed in the insulating housing of a connector.
