Description

Terminal box for protecting terminal connector

Technical Field

The utility model relates to a terminal box sets up the field, specifically is a terminal box is used in wiring joint protection.

Background

The junction box is a common wiring device and is widely applied to the aspect of circuit wiring. In home decoration, the junction box is one of the electrical accessories, because the electric wire of fitment usefulness is passed the electric wire pipe, and just adopt the junction box as transition usefulness at the connector position of electric wire (for example the circuit is longer, or the electric wire pipe is turned the corner), the electric wire pipe is connected with the junction box, and the electric wire in the spool links up in the junction box, plays the effect of protection electric wire and connecting wire, and then avoids the wire to connect and exposes in external space environment. When the wire conduit is connected, as shown in fig. 4 of the attached drawings, the wire in the wire conduit is exposed outside the junction box, and although the connector lug protects the connector of the wire inside the junction box, the wire is exposed to the external environment and cannot be protected by the junction box. When the external environment pulls the wire, the problem of wire joint fracture in the junction box can easily occur, which is not beneficial to the normal use of wire connection.

Based on the above problem, need design a terminal box for wiring joint protection, can not insert the terminal box when inside for a long time inadequately to the spool, protect the wire of inserting the terminal box inside, avoid because the wire directly exposes in the external environment, can fix the wire is fine simultaneously.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The utility model relates to a junction box for protecting a wiring joint, which comprises a main body structure, a junction box 1 and a protection device arranged at the wiring port of the junction box 1;

the protection device comprises a fixed clamping ring 2 and a wiring sleeve 3, wherein the fixed clamping ring 2 is fixedly arranged on a wiring port of the wiring box 1, and the wiring sleeve 3 is sleeved inside the fixed clamping ring 2 and can move back and forth in the fixed clamping ring 2; the inner end face of the wiring sleeve 3 is provided with a limiting ring 4; the outer end of the wiring sleeve 3 is provided with a clamping assembly 5 for clamping the inner wall and the outer wall of the conduit. When the length of spool appears and is long enough, when needing to be connected to terminal box 1 alone with the wire, be connected wiring sleeve 3 with clamping component 5 and wiring sleeve 3 for wire that wear out from the spool enters into inside terminal box 1 through wiring sleeve 3, and then ensures that the wire is protected by wiring sleeve 3. Limiting ring 4 that terminal surface set up in wiring sleeve 3 limits the position of wiring sleeve 3, avoids extracting terminal box 1 with wiring sleeve 3, if the spool is close to the too far condition of terminal box 1 distance, need take out wiring sleeve 3 from fixed snap ring 2, change longer wiring sleeve 3 carry on with be connected between the spool.

Clamping assembly 5 fixed connection is at the removal tip of wiring sleeve 3, clamping assembly 5 includes interior chuck wall 6 and excircle chuck wall 7, can mutually support between interior chuck wall 6 and the excircle chuck wall 7. When the clamping component 5 is used for being connected with a spool, the inner circle clamping wall 6 and the outer circle clamping wall 7 can be matched with each other, so that the spool is clamped between the inner circle clamping wall 6 and the outer circle clamping wall 7, and then the fixed connection between the wiring sleeve 3 and the spool is realized. And with the circular double-layered wall structure of interior circle double-layered wall 6 and excircle double-layered wall 7, can realize that the connection between wiring sleeve 3 and the spool is airtight, and then avoid factors such as external dust or moisture to cause the influence to the wire for the wire can be better protected.

And magnetic devices are arranged inside the clamping walls of the inner circular clamping wall 6 and the outer circular clamping wall 7 and are made of deformable materials. When interior circle double-layered wall 6 and excircle double-layered wall 7 mutually support, carry out centre gripping fixed action back to the pipe wall of spool, the setting can attract each other at the inside magnetic means of the double-layered wall of circle double-layered wall 6 and excircle double-layered wall 7, make the clamping action between interior circle double-layered wall 6 and the excircle double-layered wall 7 fastening more, certainly because interior circle double-layered wall 6 and excircle double-layered wall 7 are when carrying out the centre gripping, can produce deformation, consequently, the magnetic means who sets up in the double-layered wall inside is deformable material, make this magnetic means can adapt to the clamping task, for example rubber magnetic stripe or other deformable materials that have magnetism.

The outer side surface of the inner circular chuck wall 6 and the inner side surface of the outer boundary wall are rough wall surfaces. The problem that the inner circle clamping wall 6 and the outer circle clamping wall 7 slide relative to the tube wall of the wire tube cannot easily occur when the wire tube is clamped by the inner circle clamping wall 6 and the outer circle clamping wall 7 is solved. The clamping component 5 is a deformable and tough hard material; the problems that the clamping assembly 5 is broken or snapped and the like due to large clamping force when the wire pipe is clamped are avoided.

The fixed clamping ring 2 comprises an inner clamping ring 8 and an outer clamping ring 9, and the inner clamping ring 8 and the outer clamping ring 9 are connected through threads to be detachable; when the length of spool was enough to insert inside the wiring mouth to terminal box 1, can dismantle fixed snap ring 2 to the guarantee can not normally let in to terminal box 1 inside to cause the influence to the spool. The fixing clamping ring 2 and the wiring sleeve 3 are made of insulating materials.

The using method comprises the following steps:

when the wire conduit can not be normally connected to the inside of the junction box 1 due to the length problem, the fixing clamping ring 2 is fixedly installed at the junction of the junction box 1, and one end of the junction sleeve 3 with the clamping component 5 faces the outside of the junction box 1. And the wiring tower barrel is pulled to clamp the wire pipe wall by the inner circular clamping plate and the outer circular clamping plate, so that the fixed and closed connection between the wire pipe and the junction box 1 is realized.

Therefore, the wiring joint is terminal box for protection, can be to the spool when can not insert terminal box 1 inside for a long time inadequately, protect the wire of inserting terminal box 1 inside, avoid because the wire directly exposes in the external environment, can fix the wire is fine simultaneously.
