In prior art, be disclose a kind of switch cabinet state display with safeguard structure in the Chinese utility model patent of CN201220067123.3 in the patent No., comprise: the box body with opening, be arranged at the controller of above-mentioned tray interior, close above-mentioned box body and show the display floater of above-mentioned switch cabinet state, be arranged on the transparent housing outside above-mentioned switch cabinet state display, the side of above-mentioned box body is provided with wiring hole, is provided with the stopple for closing above-mentioned wiring hole in above-mentioned wiring hole.
Adopt in above-mentioned patent and stopple is set on wiring hole enters from extra wiring hole to prevent dust, steam, but due to the circular hole that the wiring hole side plate that is cabinet is formed through punching, the hole wall of wiring hole is very sharp-pointed, when wire is through wiring hole, be easy to be scratched by hole wall, cut, there is potential safety hazard.
Be and for example in the Chinese invention patent of CN201310415429.2, disclose a kind of switch cabinet instrument room terminal board cabling wire casing in the patent No.; it has installed cable harness protection sleeve in wire hole; but this cable harness protection sleeve plug is in wire hole; wear at wire and draw, be very easy to be squeezed out in the installation process that extrudes, lose its protective effect.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of middle-placed switch cabinet of the wiring hole stable with dustproof and waterproof, guardwire, protected effect.
For achieving the above object, the utility model provides following technical scheme: a kind of dust-proof middle-placed switch cabinet, comprise cabinet, described cabinet includes side plate, top board, base plate, described side plate offers some wiring holes, wherein: described wiring hole is provided with the stopple that elastomeric material is made, described stopple comprises sealed membrane and retainer ring, described retainer ring is connected with the hole wall interference fit of wiring hole, described sealed membrane sealing label is at the inner ring of described retainer ring, the hole wall of described wiring hole offers some groovings, and described grooving is evenly distributed on the hole wall of described wiring hole.
By adopting technique scheme, utilize the sealed membrane on stopple to dock string holes to close, effectively prevent external dust, steam enters cabinet inside from wiring hole, utilize retainer ring to be fixedly connected with wire connecting portion simultaneously, after removal sealed membrane, retainer ring is stayed on the hole wall of wiring hole, prevent hole wall scratch wire, further, the wire squeezes retainer ring part worn in wiring hole, retainer ring is extended to grooving reversal deformation, the contact area of retainer ring and wiring hole is made to become large, frictional force each other increases, play the effect of reinforcing described retainer ring, prevent retainer ring from coming off because of the friction of wire, elastomeric material then makes stopple have good shock-absorbing capacity, anti-wear performance, insulation property.
The utility model is set to further: described grooving is arranged on the medial surface of described side plate.
By adopting technique scheme, the wire on described wiring hole is normally pulled outwardly by cabinet inside, and the inner side at side plate opened by shown grooving, thus makes the Impact direction of the bottom land of grooving and retainer ring just right, strengthens the consolidation effect of described grooving further.
The utility model is set to further: described grooving is set to " V " shape.
By adopt technique scheme, make the bottom land of grooving narrower, strengthen the intensity of wiring hole, avoid wiring hole because of grooving offer in the friction process being wire produce distortion.
The utility model is set to further: the outer ring of described retainer ring offers annular groove, and described retainer ring passes through the hole wall grafting of this annular groove and wiring hole.
By adopting technique scheme, simplifying the mounting means of retainer ring, facilitating the connection between retainer ring and wiring hole.
The utility model is set to further: described sealed membrane and the one-body molded setting of retainer ring.
By adopting technique scheme, when needs use wiring hole, poke sealed membrane and can connect wire, install, use all very convenient, after sealed membrane is punctured simultaneously, sealed membrane can be attached to around wire, ensures that sealed membrane still can play the effect of dustproof and waterproof after wiring hole connects wire.

Embodiment
Referring to figs. 1 through Fig. 4, the dust-proof middle-placed switch cabinet embodiment of the utility model is described further.
A kind of middle-placed switch cabinet, comprise cabinet, described cabinet includes side plate 1, top board, base plate, described side plate 1 offers some wiring holes 2, wherein: described wiring hole 2 is provided with the stopple 3 that elastomeric material is made, described stopple 3 comprises sealed membrane 31 and retainer ring 32, described retainer ring 32 is connected with the hole wall interference fit of wiring hole 2, described sealed membrane 31 sealing label is at the inner ring of described retainer ring 32, the hole wall of described wiring hole 2 offers some groovings 5, and described grooving 5 is evenly distributed on the hole wall of described wiring hole 2.See Figure of description 2, described grooving 5 is arranged on the medial surface of described side plate 1, and namely this medial surface is in the one side in cabinet.
Principle of the present utility model is: utilize the sealed membrane 31 on stopple 3 to dock string holes 2 and close, effectively prevent external dust, steam enters cabinet inside from wiring hole 2, utilize retainer ring 32 to be fixedly connected with wire connecting portion simultaneously, after removal sealed membrane 31, retainer ring 32 is stayed on the hole wall of wiring hole 2, prevent hole wall scratch wire, further, wire squeezes retainer ring 32 part worn in wiring hole 2, retainer ring 32 is extended to grooving 5 reversal deformation, retainer ring 32 is made to become large with the contact area of wiring hole 2, frictional force each other increases, play the effect of reinforcing described retainer ring 32, prevent retainer ring 32 from coming off because of the friction of wire, elastomeric material then makes stopple 3 have good shock-absorbing capacity, anti-wear performance, insulation property.Wire on described wiring hole 2 is normally pulled outwardly by cabinet inside, and shown grooving 5 is opened in the inner side of side plate 1, thus makes the Impact direction of the bottom land of grooving 5 and retainer ring 32 just right, strengthens the consolidation effect of described grooving 5 further.
Again see Figure of description 2, visible described grooving 5 is set to " V " shape, and arranging of " V " shape makes the bottom land of grooving 5 narrower, strengthens the intensity of wiring hole 2, avoid wiring hole 2 because of grooving 5 offer in the friction process being wire produce distortion.The outer ring of described retainer ring 32 offers annular groove 4, and described retainer ring 32 is by the hole wall grafting of this annular groove 4 with wiring hole 2., simplify the mounting means of retainer ring 32, facilitate the connection between retainer ring 32 and wiring hole 2.Described sealed membrane 31 and the one-body molded setting of retainer ring 32, when needs use wiring hole 2, poke sealed membrane 31 and can connect wire, install, use all very convenient, after sealed membrane 31 is punctured simultaneously, sealed membrane 31 can be attached to around wire, ensures after wiring hole 2 connects wire, and sealed membrane 31 still can play the effect of dustproof and waterproof.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
