Abstract
The utility model provides a flame proof terminal box, including the junction box cover body, flame proof lock mother, rubber ring and plain washer, the internal binding post that is equipped with of junction box cover, junction box cover body downside is equipped with a plurality of outlets, is connected with logical cavity in every outlet department, circumference was equipped with the screw thread in every led to cavity, led to the outside that the junction box cover body was located to the cavity the female inner chamber of flame proof lock in be equipped with the rubber ring, the female threaded connection of flame proof lock is in leading to the cavity, the female tip that leads to in the cavity that stretches into of flame proof lock is equipped with the plain washer. The beneficial effects of the utility model are that: explode the septum primum out lead collar casing cancellation, through having logical cavity at junction box cover outlet intercommunication, reduced flame proof lead collar casing length, reduce in addition and use the part, practice thrift the cost, assemble simple and conveniently, reduced the continuous defect of junction box cover and flame proof lead collar screw, strengthen the flame proof intensity of executor greatly to improve the flame proof grade of executor.
Description
Technical field
The utility model belongs to technical field of electric equipment, especially relates to a kind of explosion-proof connection box.
Background technology
The outlet of existing flame proof actuator is all realized by flame proof lead collar, former actuator wire hole is in casing terminal box, casing is connected with flame proof lead collar by screwed hole, realize strengthening flame proof grade, but there is following shortcoming: after using flame proof lead collar, actuator line outlet place seems longer, occupies large working space; Flame proof lead collar can reduce explosion suppresion surface and flame proof intensity greatly with being threaded between terminal box, causes can not realizing flame proof effect very well.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, the flame proof intensity of strengthening actuator, cost-saving and assemble explosion-proof connection box simply and easily, be especially applicable to being applied to actuator outlet and increasing flame proof grade.
The technical solution of the utility model is: a kind of explosion-proof connection box, comprise terminal box lid, flame proof locknut, cushion rubber and plain washer, binding post is provided with in described terminal box lid, multiple line outlet is provided with on the downside of terminal box lid, cavity body is connected with at each line outlet place, each cavity body inner circumferential is provided with screw thread, cavity body is located at the outside of terminal box lid, cushion rubber is provided with in the inner chamber of described flame proof locknut, flame proof locknut is threaded in cavity body, and the end that flame proof locknut extend in cavity body is provided with plain washer.
Further, 3 line outlets are provided with on the downside of described terminal box lid.
Further, described cavity body and terminal box lid are structure as a whole.
Further, the internal diameter of described cavity body is greater than the diameter of line outlet.
Further, described plain washer is arranged near the external wall of connector cover.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, septum primum is produced line set of shells to cancel, by being communicated with cavity body at connector cover line outlet, decrease flame proof lead collar shell length, and reduce use part, cost-saving, assemble simple and convenient, decrease the defect that connector cover is connected with flame proof lead collar screw thread, greatly strengthen the flame proof intensity of actuator, thus improve the flame proof grade of actuator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, terminal box lid 2, flame proof locknut 3, cushion rubber
4, plain washer 5, line outlet 6, cavity body
Embodiment
As shown in Figure 1, the technical solution of the utility model is: a kind of explosion-proof connection box, comprise terminal box lid 1, flame proof locknut 2, cushion rubber 3 and plain washer 4, binding post is provided with in described terminal box lid 1, multiple line outlet 5 is provided with on the downside of terminal box lid 1, cavity body 6 is connected with at each line outlet 5 place, described cavity body 6 is structure as a whole with terminal box lid 1, each cavity body 6 inner circumferential is provided with screw thread, cavity body 6 is located at the outside of terminal box lid 1, cushion rubber 3 is provided with in the inner chamber of described flame proof locknut 2, flame proof locknut 2 is threaded in cavity body 6, the end that flame proof locknut 2 extend in cavity body 6 is provided with plain washer, described plain washer 4 is arranged near terminal box lid 1 outer wall, the internal diameter of described cavity body 6 is greater than the diameter of line outlet 5, be convenient to plain washer 4 and keep off edge outside line outlet 5.
In the present embodiment, on the downside of described terminal box lid 1, be provided with 3 line outlets 5.
The course of work of this example and principle: septum primum is produced line set of shells and cancel, by being communicated with cavity body at connector cover line outlet, decrease flame proof lead collar shell length, and reduce use part, cost-saving, assemble simple and convenient, decrease the defect that connector cover is connected with flame proof lead collar screw thread, greatly strengthen the flame proof intensity of actuator, thus improve the flame proof grade of actuator.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
