Cable, protective hose, and snow attachment screw connection (fixed and detachable connection)

j The invention relates to a cable protection hose quick

Fastening screw connection for cable protection conduits of various types outer profile shape for fixed una detachable ' Connection, with fixed or rotatable threaded connection, optionally Screw connection holder. Made of plastic, for quick attachment to machines, robots, devices, control cabinets , Cable collecting points, etc. consisting of a plastic housing mounting piece. a plastic spring clip latched, Fuse sealing cap and rubber seal.

Cable protection hose quick-release screw connections are known different designs, e.g. DBGM G 85 o3 οδο.5 which by means of a clamping basket with Rastzähr.en and Ge ι housing part with locking mechanism, by firmly pressing in the

Protective hose the same is tightened.

Also known are cable protective corrugated hose quick fastenings made of plastic, consisting of a housing receiving piece which receives the plastic protective corrugated hose and the same through a plastic slide which is pressed into the housing receiving piece. The bars attached to the inside of the plastic slider grip the corrugated plastic hose (Profjl) and hold it firmly in the housing receiving piece. The notch on both sides at the end of the plastic slider does not offer sufficient security to hold the protective corrugated hose • in the housing receiving piece, especially if

the protective hose is jolted or moved. Even when assembling and disassembling the plastic protective corrugated hose difficulties arise when pushing in and reading the plastic slide ends *

In addition, according to the manufacturer's brochure, these quick-release screw connections can only be used for protective corrugated hoses will.

These disadvantages are eliminated by the present innovation. Housing mounting piece with the circumferential groove and partial groove after the protective hose has been pushed into the housing mounting piece, by means of the plastic spring clip pressed into the housing receiving piece until it engages in the locking mechanism of the housing. Here is through the profile web on the plastic spring clip, this is pressed into the protective hose profile and thus the Protective hose fastened in the housing mounting stick. In order to obtain better security against unintentional opening and pulling out of the protective tube, a Safety slide arranged on the safety sealing cap, which is pushed over the latched spring clip and thus an unintentional loosening of the spring clip or the protective hose cannot occur. The rubber seals on the fuse sealing cap and in the housing receptacle seals the cable and the protective hose against dust and moisture.

It is ensured that the clip locks when the spring engages in the housing receiving piece the inserted protective hose is firmly connected to the housing receiving piece.

If the protective tube has to be removed for any reason, the safety slide on the safety sealing cap is pushed back and the Spring clip notch raised until it engages in the upper locking groove in the housing receiving piece. In this position the protective hose can be pulled out of the housing receiving piece and remains in this position until it is renewed The protective hose is attached.

This work process, i.e. the flawless loosening and fastening of the protective hose is only possible with the plastic spring clip, as this ensures an absolutely safe loosening and fastening of the protective hose through its own spring action »

Fig. 2 shows a partial section of the cable protection hose quick-release screw connection with the housing mounting piece 1 and the plastic spring clip 2 which is in the fully depressed locking position 6 (see Fig. 5) is locked in the housing mounting piece. The lower part of the spring clip 5 (see Fig. 3) is located in this position in profile 8 of the protective hose, (see Fig. 6). The safety sealing cap 3, which is provided with a rubber seal 4, to prevent penetration To avoid dust or moisture, is arranged with a safety slide 3a (see Fig. 4 ·).

Should the clamped protective hose be loosened and pulled out the safety slide 3a on the safety sealing cap 3 must first be pushed back. With Use a screwdriver to lift the plastic bracket 2 on the marked housing mounting piece so that until it engages in the detent 7 (Fig. 1 and 5). The protective hose is now free and can be removed from the Housing receiving piece can be pulled out. The slot recess 9 (FIGS. 4 and 5) in the housing receiving piece serves to guide the bracket 5 (Fig. 3) of the plastic spring clip notch 2. The two on both sides Knobs 12 arranged at the end (FIG. 3) enable a good engagement.

The rubber seal 1o (Fig. Ί) ± m housing adapter seals the cable and protective hose against dust and moisture.
