Abstract
The utility model discloses a wiring hole structure for a weak current protective tube of a switch cabinet. The wiring hole structure is characterized in that the wiring hole structure comprises a plurality of wiring holes disposed on a side, facing a switch module in a cabinet body, on the protective tube; the wiring holes are vertically spaced; wiring hole covering parts are embedded onto the wiring holes; the central portion of each wiring hole covering part is provided with a layer of thin film having a thickness of 0.1-0.3cm and being made of rubber material. The wiring hole structure provided by the utility model conveniently leads weak lines to respective switch modules, can keep a sealed protective effect, and also has the advantages of simple structure and stable and reliable installation.
Description
Technical field
The utility model relates to a kind of switch cubicle, especially relates to a kind of switch cubicle light current protection tube cable hole structure.
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.But wherein, consider how to design a kind of cable hole structure, make it both facilitate weak electric wire is drawn out to each switch module, can keep closed protective effect again.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of both convenient weak electric wire is drawn out to each switch module, can keep again the switch cubicle light current protection tube cable hole structure of closed protective effect.
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 structure; it is characterized in that; comprise on protection tube towards a plurality of cable holes that arrange on the side of cabinet internal switch module; cable hole arranges along vertical interval; on described cable hole, be also embedded with cable hole covering, described cable hole covering mid portion is that a layer thickness is the film that the elastomeric material of 0.1-0.3cm makes.
In the utility model, be provided with cable hole covering on cable hole, break cable hole covering and draw during cabling, cable hole covering can be filled up the leak of cable hole, and weak electric wire in protection tube is played to better protective effect.Wherein cable hole covering mid portion is set to the film of certain material and thickness, in the time of can facilitating cabling, breaks.Cable hole is arranged on protection tube towards the side of cabinet internal switch module, can facilitate weak electric wire to draw from protection tube and be wired in corresponding switch module.
As optimization, described cable hole covering has a columnar part being embedded in cable hole, and being embedded the inner into cable hole part, to have a width be the flange that 2-5mm cross section is most advanced and sophisticated inside wedge shape.Like this, can guarantee that cable hole covering is embedded soundness, avoid in the process of carrying or switch gate, cable hole covering, because vibration drops out, improves fail safe.
As another optimization; described cable hole covering has the part outside cable hole that is exposed to that a diameter is greater than cable hole diameter, described in be exposed to the medial surface being affixed with protection tube surface in the part outside cable hole and be provided with one deck mucigel and be bonded in protection tube surface by this mucigel.Like this, can further guarantee cable hole covering installation soundness, avoid dropping out, improve fail safe.
In sum, the utility model is both convenient is drawn out to each switch module by weak electric wire, can keep closed protective effect again, also has simple in structurely simultaneously, and reliable and stable advantage 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, described in be exposed to the medial surface being affixed with protection tube surface in the part 6 outside cable hole and be provided with one deck mucigel 7 and be bonded in protection tube 1 surface by this mucigel.
Wherein, at cabinet inwall, be provided with vertical protection metal pipe, like this, 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.
