Abstract
The utility model discloses a wiring hole covering part for a weak current protective tube of a switch cabinet. The wiring hole covering part is characterized in that the wiring hole covering part is provided with a portion having a diameter greater than the diameter of a wiring hole and being exposed outside the wiring hole; in the portion exposed outside the wiring hole, an inner side for being attached to the surface of the protective tube is provided with an adhesive layer; and a gummed paper layer is further disposed outside the adhesive layer. The wiring hole covering part provided by the utility model has the advantages of being easy to install, being capable of ensuring reliability and firmness so as to guarantee safety effects and also being easily broken to facilitate wiring, and improving the convenience of installation and wiring.
Description
Technical field
The utility model relates to a kind of switch cubicle light current cabling protection member, especially relates to a kind of switch cubicle light current protection tube cable hole covering.
Background technology
Switch cubicle is in electric control system, to play the integrated cupboard obtaining in a cabinet that is arranged on of switch module of the effects such as break-make, control or protection.For occasions such as electric power system generating, transmission of electricity, distribution, electric energy conversions, use.Existing switch cubicle, its general structure is comprise as the cabinet of shell and be arranged on the various switch control modules in cabinet.
Switch cubicle weak electric wire refers to, controls the circuit of the weak current parts such as power supply or mains lighting supply or signal of communication line in cabinet for connecting each control module.Existing switch cubicle weak electric wire is to be all directly laid in switch cabinet body, but due to the module being generally all equipped with in switch cubicle for the electric energy conversion of heavy current or strong voltage, therefore usually form powerful electromagnetic field in cabinet, weak electric wire is caused and disturbed and infringement.
In order to address the above problem; applicant considers the protection tube at the metal material of the vertical hollow arranging of switch cabinet body inwall one side; like this; weak electric wire can be arranged in protection tube; protection tube can avoid weak electric wire to be subject to impaction lesion and electromagnetic interference, plays the double action of physical protection and electromagnetic protection.Consider to arrange cable hole simultaneously and carry out cabling to switch module on protection tube, a covering is set in cable hole and protects, during cabling, break covering and carry out cabling.
But wherein, with regard to needing, consider how to design a kind of convenient installation, can guarantee to fix reliably to guarantee safe effect, can also conveniently break the covering component structure that carries out cabling simultaneously.
Utility model content
For above-mentioned the deficiencies in the prior art; technical problem to be solved in the utility model is: how a kind of convenient installation is provided; can guarantee to fix reliably to guarantee safe effect, can also conveniently break the switch cubicle light current protection tube cable hole covering that carries out cabling.
In order to solve the problems of the technologies described above, in the utility model, adopted following technical scheme:
A kind of switch cubicle light current protection tube cable hole covering; it is characterized in that; described cable hole covering has the part outside cable hole that is exposed to that a diameter is greater than cable hole diameter; in the described part being exposed to outside cable hole, for the medial surface being affixed with protection tube surface, be provided with one deck mucigel, outside mucigel, be also provided with one deck gummed paper layer.
When the utility model is used, tear gummed paper layer and install, after installing, by mucigel, be bonded in protection tube surface, can guarantee cable hole covering installation soundness, avoid dropping out, improve fail safe.
As optimization, described cable hole covering have one columnar for being embedded the part in cable hole, and be embedded the inner into cable hole part and there is the flange that a cross section is most advanced and sophisticated inside wedge shape.Flange width is preferably 2-5mm, has so not only been beneficial to insertion but also can have guaranteed that firm effect is better.After optimizing like this, the flange of unique texture, can guarantee that cable hole covering is beneficial to embedding and is embedded soundness, avoids in the process of carrying or switch gate, and cable hole covering, because vibration drops out, has improved fail safe.
Further optimize, described cable hole covering mid portion is that a layer thickness is the film that the elastomeric material of 0.1-0.3cm makes.Like this, cable hole covering mid portion is set to the film of certain material and thickness, in the time of can facilitating cabling, breaks.
In sum, the utlity model has convenient installation, can guarantee to fix reliably to guarantee safe effect, can also conveniently break and carry out cabling, improve the advantage that cabling convenience is installed.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation sketch that has adopted the switch cubicle light current cabling protection mechanism of the utility model structure.
Embodiment
Below in conjunction with a kind of switch cubicle light current cabling protection mechanism that has adopted the utility model structure and accompanying drawing thereof, the utility model is described in further detail.
During concrete enforcement; as shown in Figure 1; a kind of switch cubicle light current cabling protection mechanism that has adopted the utility model structure; the protection tube 1 that comprises the metal material that is positioned at the vertical hollow arranging of cabinet inwall one side; on protection tube 1, on the side of cabinet internal switch module, be provided with a plurality of cable holes, cable hole arranges along vertical interval.The protection tube that described protection tube 1 is rectangle for cross section, is also embedded with cable hole covering 2 on described cable hole, described cable hole covering 2 mid portions are that a layer thickness is the film 3 that the elastomeric material of 0.1-0.3cm makes.Described cable hole covering 2 has a columnar part 4 being embedded in cable hole, and being embedded the inner into cable hole part 4, to have a width be the flange 5 that 2-5mm cross section is most advanced and sophisticated inside wedge shape.Described cable hole covering 2 also has the part 6 outside cable hole that is exposed to that a diameter is greater than cable hole diameter; the medial surface being affixed with protection tube surface in the described part 6 being exposed to outside cable hole is provided with one deck mucigel 7, is also provided with one deck gummed paper layer 8 outside mucigel.
The switch cubicle of said mechanism is installed, when carrying out light current cabling, need to first takes off cable hole covering, tear gummed paper layer 8; Then after weak electric wire being drawn through film 3, then cable hole covering is installed back to original position.
Like this, at cabinet inwall, be provided with vertical protection metal pipe, weak electric wire can be arranged in protection tube, and protection tube can avoid weak electric wire to be subject to impaction lesion and electromagnetic interference, plays the double action of physical protection and electromagnetic protection.On cable hole, be embedded with cable hole covering, during cabling, conveniently break cable hole covering and draw, the unique texture of covering both can be filled up the leak of cable hole, facilitated again cabling, also has solid and reliable feature is installed, and had improved switch cubicle fail safe.
