"Electrical plug with and without protective contact for moving

electric lines"

The innovation relates to an electrical connector with or without a protective contact for moving electrical lines, in which eliminating any contact and fastening screws and other fastening ^ - or locking elements made of metal or the like, such as clamps, strain relief clamps, etc. a pin plate expediently made of insulating material by pressing and snapping under a press fit two on it riveted, articulated via IPilmsonaniere, on the outer surface with saw-like, offset teeth that lock in the pulling direction and are laterally resilient Legs, in corresponding bulges located in the handle part of the connector housing, inextricably linked to the upper part of the connector is connected to one another and at the same time the protruding on the inside of the fastening legs, the Locking cams used for strain relief when the legs are pressed together in this way around the inserted connector cable, which is bent in a U-shape grab that when the legs are pressed into the connector housing with a press fit, the protruding ones at the same time Center points, ridges or hoops are pressed into the cable sheathing and a reliable and safe strain relief of the Connector cable is achieved, and the permanent connection between the connector plate and the housing part and at the same time also the Cable strain relief will inevitably get stronger and tighter, ever the tensile stress on the cable is greater »

Electrical connectors that have a pin plate with a connector housing or a cap or two connector halves be connected by bolts, nuts, etc. and where

the cable connections through contact pressure screws and the strain relief through "special clamps and fastening screws successes are sufficiently "known and have these designs almost all significant IT disadvantages, such as! emergence of 'iackelkontakten or. short circuits, caused by the ! • Loosening cables and, last but not least, the dangerous ones Possibility of the plug - opening by laypersons, whereby serious accidents even with fatal outcome cannot be excluded,

Ince the molding-the connector pin - support plates and the cable terminals with plastic were the above Geesthacht parts namely _s eliminated but it is umständlichj the manufacturing process, however, ■, time consuming and expensive, HL, especially with Pe 'sprayings and contact circuits in the plug ■ - the interior of the entire plug is no longer to be used and most of the time it is the consumer. _s as far as he does not himself manufacturer i & t, complete ± ensre cable cords with molded plugs with cumbersome, transport and high transport costs. Here, still gives the ■ Hachteil that so not all cables, depending on the type of coating, extrusion coating can _see many of the test subject electrical equipment shall not be used *

There are too. Known _{connector designs 9} whose connector halves or - "" - parts by means of special 3perrorgane ₅ such as clamping bracket coupling elements made of metal: or the like according to the known locking principle. or have the locking devices bent open again and additional strain relief devices have to be used.

The present! Inflation is supposed to serve the purpose? To create an extremely inexpensive plug with «the without earthing contact when using the smallest components, ie at extreme manufacturing costs, which can no longer be opened with the shortest assembly times and in which the leads can be connected to the connector pins and by simply hitting or soldering to the ground contact ₃ results in a solid electrical connection

Avoidance of dismantling and repair options.

The fire is illustrated using the drawing and shown and show?

The plug with and without a protective contact for movable electrical lines essentially consists of the plug pin plate with the plug pins 2 _{$, provided with locking grooves or riveted in, with the plug pins 2 $ and the} plug housing 3 with the central side or without the insertion grommet 4 _{and the 3} riveted to the connector pin plate 1 in a recess 5 by means of film sonaniere 6 articulated to each other j Y-shaped bent and resilient mounting legs 7 $ after the cable assembly 13 and the pushing of the connector plate 1 into the housing 3 under a press fit with their ratchet teeth 8 that run transversely on the outer surface and are offset from one another, they permanently snap into corresponding bulges 9 in the handle part of the connector housing 3 and at the same time serve to relieve the strain on the eyes. locking cams provided with bores and centering pins 11 12, which after inserting the U-shaped bent cable 13 and when. Compressing the Y-shaped bent legs 7 so urge the cable and lock that ensures a simple but reliable strain relief due to their staggered _arrangement: is. In the salty thigh area, you can also

resilient storage webs 14 are arranged, which in corresponding Housing ever deepen intervene and thus the insoluble lceit the blocking connection favorably influence.

A circumferential sharp edge 15 on the base plate 1 also engages in a corresponding hat on the lower hand of the housing cap 3 and during the assembly. Two guide cams 16 protruding from the connector plate grip around the edge of the elastic housing cap 3 in order to give it additional support on the side and at the same time to give the assembled plug a noticeably visible, wear-resistant insertion cams.

To secure the plug cable against rotation, the inner surfaces of the legs have protruding grooves or points 17, which, in addition and inevitably, when the fastening legs 7 are pushed into the connector housing 3 with a press fit Press into the cable jacket.
