Abstract
The invention discloses an electrical box which comprises an electrical box body, a junction box, external cables and cable glands. The junction box is arranged on a side wall of the electrical box body. The inside of the junction box is communicated with the inside of the electrical box body. Multiple line passing holes are formed in the upper portion of the junction box. The external cables penetrate through the line passing holes. The portions, penetrating through the line passing holes, of the external cables are provided with the cable glands. Multiple round holes are formed in a side wall of the electrical box body. The inside of the junction box is communicated with the inside of the electrical box body through the round holes. Wiring terminals are arranged in the round holes. The external cables penetrate through the line passing holes and the cable glands and are connected with external wiring points of the wiring terminals. Electric part connection wires in the electrical box body are connected with internal wiring points of the wiring terminals. According to the electrical box, possibilities that during wiring operation, precision parts in the electrical box body can be damaged and some sundries which have electrical hazards can remain in the electrical box body are reduced.
Description
Technical field
The present invention relates to a kind of electric box, relate in particular to the electric box of a kind of subway pulling equipment used.
Background technology
Current subway field, the electric box of the pulling equipment that subway is used external cable access electric box in scheme generally have:
Scheme one: directly opening square hole on the electric box casing, and use is with some covering on the square hole on closed box of line circular hole excessively, and external cable directly arrives the inside of electric box by the cover plate cable-through hole, and is connected to corresponding wiring point.External cable is worn the position of cable-through hole and is generally used gland head sealing, protection.
Scheme two: as shown in accompanying drawing 1,2, at electric box main body 1 casing appropriate location opening square hole 2, weld one week sheet metal around square hole 2, cover closure is used in side, form similar junction box's 3 structure, at the some cable-through holes 4 of junction box's 3 upper design, external cable 5 enters the inside of electric box main body 1 through gland head 6 through junction box 2, finally be connected on busbar 7.
This two schemes all needs to make the component exposed in the electric box main body in the process that connects external cable, wiring operates in to be carried out between electric component in the electric box main body, easily hurt the precise part in the electric box main body, and easily leave over some foreign material that electrical hazard is arranged in the electric box body interior.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind ofly to make wiring operate in the electric box that carry out in the electric component outside in the electric box main body.
Technical solution of the present invention is achieved in that a kind of electric box, comprise electric box main body, junction box, external cable and gland head, the sidewall of described electric box main body is provided with the junction box, described junction box is inner to communicate with the electric box body interior, described junction box's top is provided with a plurality of cable-through holes, described external cable is through cable-through hole, and described external cable is provided with gland head through the position of cable-through hole, has a plurality of circular holes on the sidewall of described electric box main body; Described junction box inside communicates with the electric box body interior by circular hole; Be provided with binding post in described circular hole; Described external cable is connected with the outside wiring point of binding post with gland head through cable-through hole; Electric component connecting line in described electric box main body is connected with the inboard wiring point of binding post.
Preferably, described binding post comprises method mounting flange and screw; Described screw is arranged on the two ends of mounting flange; Described mounting flange is arranged in circular hole.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Electric box of the present invention, external cable through gland head and cable-through hole through the junction box, with the outside wiring point of binding post, be connected, electric component connecting line in the electric box main body is connected with the inboard wiring point of binding post, make access point electric component relative isolate interior with the electric box main body, the wiring operation occurs in the electric component outside, hurts the precise part in the electric box main body while reducing the wiring operation and leaves over the possibility of some foreign material that electrical hazard is arranged in the electric box body interior.
