Cable strain relief holder

The innovation relates to a cable strain relief holder made of limited elastic material, especially for U-shaped profiled office furniture legs according to the preamble of the main claim.

Cable strain relief holders of the type mentioned are generally known and come in particular to standard and Control housings for use to remove the tensile loads that may be caused by the cables from the cable connections in the housings. As a rule, these are cable strain relief holders around bracket-like elements made of plastic, in the form of laterally open eyelets into which the cables are pressed and can then be clamped with clamping elements.

Such cable strain relief requirements are now also made for office furniture, in particular desks or work tables, through their legs Usually a large number of cables are routed for electrical devices standing on the table of all kinds (typewriters, telephones, data processing equipment or the like). For such a purpose the previously known cable strain relief holders are not suitable because they are not on the one hand can easily be attached to the furniture legs

■ can and, on the other hand, the space available for this usually not enough. Since the furniture legs too must meet the relevant requirements in terms of their external appearance this is not simply drilled and the cable strain relief holder screwed onto it. To be considered is also that at least the furniture leg base profile is usually U-shaped in cross section is designed and not every leg is equipped with permanently installed cable strain relief holders from the outset because the free leg cross-sections often have to be kept free for other reasons.

The innovation is therefore based on the task of a cable strain relief holder, in particular for office furniture legs to create that is simply designed and just as easily detachable in the inner cross-section of the furniture leg, but firmly seated, can be attached with the proviso that the cables to be fixed without "threading" can be inserted and fixed in the cable strain relief holder.

This task is with a cable strain relief holder of the type mentioned after the innovation by those listed in the characterizing part of the main claim Features solved. Advantageous further developments result from the subclaims.

Due to the two-part design of the cable strain relief

stungshalter and the · equipment of the holding bracket with outward-facing, lockable cooling elements this retaining bracket can be easily pressed and locked into the U-shaped leg profile, this of course with corresponding holding element receiving openings must be provided. The holding elements are preferably in the form of protruding tongues formed on the legs of the retaining bracket. As a rule, the U-shaped leg profiles exist with regard to their side legs made of double wall profiles, so that the receiving openings for the holding elements, attached to the inner walls of the double-walled sides without appearing to the outside at all can be. The retaining bracket is therefore only at the relevant point on the leg where these retaining openings are intended to be pressed in, then the cables must be inserted into the completely open retaining bracket and then the push-in bracket is pushed over the whole thing in order to then, if at all necessary, the Clamp the insert bracket existing clamping elements.

The inner surfaces of the legs of the retaining bracket and the outer surfaces of the legs of the push-in bracket are included Advantageously with locking elements, such as corrugations, sawtooth profiles or the like. Provided to to be able to lock the two brackets securely against each other. Furthermore, the legs of one or the other other bracket with stop bars, which the-

art are arranged on the brackets so that they do not detach from each other when subjected to tensile load can. The stop bar would therefore sit at the bottom of the retaining bracket or above or with the insert bracket on both brackets correspondingly below and above.

The novel cable strain relief holder is illustrated below with the aid of the graphic representation of a Embodiment explained in more detail.

It shows schematically

3 shows, in section, a particular embodiment of the cable strain relief holder.

As can be seen from Figs. 1 to 3, the cable passage piece 1 consists of two U-shaped, along their Legs 2, 3 clip-in and latchable brackets 4, 5, the one with the cable clamping elements 11 provided insert bracket 4 receiving bracket 5 is provided with outwardly directed, latchable retaining elements 6. In the illustrated, practical embodiment are the holding elements 6 in the form of projecting tongues 6 'on the legs 2 of the holding

bracket 5 formed. For these tongues 6 ', corresponding openings 14 are punched into the inner side walls 12 of the furniture leg profile, in which the tongues 6' of the retaining bracket 5 that is simply pressed into the leg profile lock. In order to avoid other cumbersome but possible connecting elements for the two brackets 4, 5, the inner surfaces of the legs 2 of the retaining bracket 5 and the outer surfaces of the legs 3 of the insert bracket 4 are provided with latching elements 7, which, as shown, are advantageously designed as sawtooth profiles. This Sägezahnprofilierungen both stirrups are oppositely directed, so that the two brackets can be one hand slightly compressed in the position shown in Figure 2, on the other hand in ^printing. Pollution from the inside but can not solve. The latching effect of the tongues 6 'is reinforced by the push-in bracket 4, so that the entire cable strain relief holder is securely seated in the furniture leg profile 13, for which the lower end is mainly used. As already mentioned, the legs 2, 3 of one and / or the other bracket 4, 5 are provided with stop strips 8 according to FIG. 3, which ensure that in extreme cases and under tensile load, the two brackets do not move perpendicular to their insertion direction can. The retaining bracket can also expediently be provided with at least one duct divider 10 on its base web 9.

Depending on the strength and number of cables to be held, it may be sufficient to have both brackets 4, 5 on the inside Equip clamping elements 11 in the form of more or less sharp-edged ribs and thereby the Push-in bracket 4 so far into the retaining bracket that the cable is captured by these clamping elements 11 ' will. Apart from this, however, it is also possible to use the insert bracket instead of or in addition to the holding elements 11 'in the form of transverse ribs, as indicated in FIG. 2, to arrange screw-in clamping elements.

Since the brackets 4, 5 are made of limited and tough elastic plastic material, the strain relief holder can also be easily removed overall by using an auxiliary tool, for example Latching elements of the legs loosens from each other and first pulls off the insert bracket or, in the case of the 3, the push-in bracket 4 simply pushes upwards out of the retaining bracket 5. Since then the legs 2 of the Bracket 5 are exposed, these legs can be slightly bent inwards and thus the tongues 6 'out the openings 14 are disengaged.
