EP0603846B1 - Antibending device - Google Patents

Abstract

The antibending device comprises an articulation element (4) which tapers in the extent of the cable, can be bent elastically by means of recesses (5) in the material and can enclose a plug cable (3) and has joined to it on the plug side a housing (2) which encloses a plug (1). Here, the housing (2) which is integral with the articulation element (4) consists of two half shells (5,6) which are connected to one another by means of a film hinge (8) so as to be capable of being folded closed and folded open. <IMAGE>

Description

The present invention relates to an anti-kink device made of plastic for cable plugs, especially for IT systems u. Like. Where the emerging from the connector housing Cable through a tapering in cable extension Material recesses on at least one side elastically bendable joint piece is guided on the one intended to enclose part of a plug Connects housing.

Anti-kink devices of the aforementioned type on cable plugs are common to having cable breaks due to turning to prevent too small a radius. This is particularly from of great importance, on cable plugs for communication networks, like computer systems, where micro plugs with a variety thinnest copper wires or glass fibers the world standardized connection standards for telecommunication and data communication connections guarantee.

Kink protection devices of this type are either with Potted plugs and cables or from the cable side after wiring pushed onto the connector and latched or glued.

In both cases, the connector will indicate connection errors or unusable for connection changes and must be complete Supply line and kink protection device must be replaced.

A kink protection device according to the preamble of claim 1 is known from US-A-4 734 055.

It is therefore an object of the present invention to To provide an anti-kink device of the aforementioned type, that can be applied on site and can be removed as required and is interchangeable.

This is achieved according to the invention in that the Joint piece connects in the cable extension to the connector housing and tapers and is formed in one piece with the connector housing, the joint piece and connector housing being common two, preferably connected to and hinged together via a film hinge Half shells exist.

These measures now allow any of them Equip the connector in question with a Kink protection device, which, for example for colored connection marking, can be replaced as required.

For easy handling with secure locking of the The two half-shells can be the design of the subject of the invention preferably be such that the closed Half shells can be locked by detachable tab means.

1 includes a, itself tapering in cable extension due to material expansion 5 (Fig. 2) elastically bendable, a plug cable 3 enclosable Joint piece 4, on which there is a connector a housing 2 enclosing a plug 1.

This known anti-kink device preferably consists made of plastic.

This kink protection device is preferably shielded AMP and DDKRJ45 connector 1 used.

According to the invention is now according to FIGS. 2 to 5 with the joint piece 4 one-piece housing 2 from two half-shells 6,7 formed here with each other via a film hinge 8 foldable and foldable connected, which is any non-destructive Exchange allowed.

The closed half-shells 6, 7 are removable Latch means lockable. These tab means initially include a molded tongue-like tab 18 on the conductor side End of the anti-kink device when closed Half shells 6.7 around which a half shell is guided and hooked onto a barb 18 '. Further a T-tongue 19 is formed on the plug end, the engages under a counter groove 19 'in the closed state.

There is also a centering pin on a half-shell 6 or 7 10 provided, which with closed housing 6.7 in a counterbore 10 'engages in the other half-shell.

The kink protection device according to the invention can be used in any Colors can be designed, whereby also the flat Design in particular the housing part 2 the attachment allowed by labels.

Claims (2)

1. Anti-kink device of synthetic material for cable plugs (1), especially for computer apparatus, where the cable (3) issuing from the plug casing (2) is guided by an articulation member (4) which is connected to the plug casing and resiliently bendable to at least one side by virtue of recesses in the material, characterised thereby that the articulation member (4) is connected to the plug casing (2) in the direction of the cable, tapers and is formed integrally with the plug casing (2), wherein articulation member and plug casing consist in common of two half shells (6, 7) connected together, preferably by way of a film hinge (8), to be foldable together and openable up.
2. Anti-kink device according to claim 1, characterised thereby that the closed half shells (6, 7) are lockable by releasable strap means (18, 18'; 19, 19').
