"Insulation housing for the metal canister made of a pin and Buohse existing electrical plug connection ".

PRIORITY t January 15, I964 - UK.

The invention relates to an insulating housing for the metal can an electrical plug connection consisting of a pin and socket one end has a tubular part for receiving a contact pin and at the other end it goes into a tab-like part Part over to which the stripped end of an electrical cable is attached

The main aim of the invention is to create an insulating

housing, which prevents unintentional adjustment of the associated metal bushing after it has been inserted into the housing «

Another object of the invention is to provide a strip-like unit made up of a plurality of mutually parallel arranged housings of the type mentioned, from which a desired number of connected housings is separated can be used to contact them for an appropriate number of times to use pens

For this purpose, the invention is based on an insulating housing for the metal sleeve consisting of a pin and socket electrical connector, so that according to the main feature of the invention, this housing is characterized by a tubular part with ends open on both sides made of a synthetic plastic material, a resilient one strip-like part, which extends in the longitudinal direction of the tubular part and each has a projection on its inner Has surface which is arranged so that it has a metal bushing in axial locking engagement against Versohieben during Insertion of the associated contact pin stops after the latter has been inserted into the housing · TTb to prevent unwanted displacement of the metal bushing within the housing in the opposite direction, i.e. when pulling out

009822/037 3 - 3 -

pulling of the Kontaktatiftee can occur, according to a further feature of the invention, that the end of the exact "·" for receiving the Steokstiftee of the connection with a lip protruding into the housing is provided, which is an anchor for the limitation of the position of the socket this end of the housing is used.

The aforementioned resilient strip-like part of the Housing is manufactured according to the invention in such a way that the wall of the housing is provided with longitudinal sole seats which run parallel to one another and which have a leave a narrow, flexible casing strip that is close to the can bend outside when a metal bushing is inserted into the housing.

With these: strip-like housing part is according to the invention

the inner projection is wedge-shaped and with a

The shoulder surface behind a paragraph of the metal {

socket engages after the latter has been inserted into the housing has been·'

Another feature of the invention is to combine a plurality of insulating housings of the invention into a unit, so that according to the invention this unit consists of consists of a single molding strip, which is a band-like

Has a bridge part} of which the individual housings lie side by side and run parallel to one another go out «Here, according to the invention, the individual housings can be connected to one another by a connecting web or only a small distance from one another, so that • in part of the unit with a respectively desired number of Housings can be separated by placing the ribbon-like bridge part and the connecting web at the respective position This in turn results in units of laterally interconnected housings that can be provided with metal connectors to accommodate a corresponding number of contact pins.

Haoh a special feature of the invention can also be provided be that the connecting webs between the housings end just before the Steokstiftaufnahmeende of the housing, so that a bending of the unit or a series of housings in the plane of the housing row in the manner of a circle or segment of a circle becomes possible.

Two exemplary embodiments of the invention are presented described below using schematic drawings *

4 and 5 each show a side view of a further embodiment.

The housing 1 are in the illustrated examples of the invention, Any number of e.g. 6 pieces lying next to each other in rows, if necessary with intermediate strips separated from one another, combined as a structural unit and held together at one end by a band-like bridge part 2. Each of the housings 1 made of insulating flexible material is provided with a pair of mutually parallel ones Provided slots 3, which leave a resilient strip-like part 4 between them, which is when Insertion of an associated bushing bends outward. the inner surface of this strip-like part 4 is provided with a wedge-like projection 5.

Fig. 3 shows such a housing 1 in longitudinal section) the same takes a metal can according to the invention, the for inserting a contact pin (not shown)

having tubular part 6, the rear end of which as indicated at 7, an abutment or a shoulder on the Forms point at which this part 6 merges into a part θ, which has tabs or tongues that are stripped to the Be clamped at the end of an electrical line

The arrangement is such that the said metal bushing can be inserted into the housing 1 in the direction of the arrow A (fig 3), the strip part 4 yielding and bending outwards as a result of the pressure of the metal bushing against the projection 5, so that an insertion of the socket part 6 can take place. When this part 6 is in its correct position in the housing 1, the strip part 4 jumps back again and spends the shoulder surface at the thicker end of the projection 5 behind the paragraph 7 of the metal bushing in the blocking position, so that this bushing can be unintentionally pulled out in the opposite direction Direction is prevented. The forward movement of said bushing in the direction of arrow A is limited by a projection or a lip 9 on the housing mouth, against the inner surface of which the mouth or bushing rests.

Compared to FIGS. 1 and 2 of the drawings, in the embodiment of FIGS. 5 and 4, the connecting webs 2a of the housing 1 are kept shorter, so that gaps 10 between the

Pin receiving ends of the housing 1 remain. These gaps 10 and the flexible material of the housing 1 provide the possibility of a strip-like combined to form a unit plurality of housings 1 slightly arcuate form, as shown in Fig. 5 to the individual housing 1 adapt to possible Üngenauigkeiten _t formed between the centers of a corresponding row of contact pins "can exist with which such a housing unit is to be connected.
