Abstract

The utility model discloses a can promote binding post of waterproof performance, including the end button box a plurality of mounting grooves have been seted up on the end button box inlay the terminal that is equipped with copper in the mounting groove, the terminal includes the shaft the front of shaft is formed with at least twice draw-in groove the winding has rubber seal on the shaft, and this rubber seal is in the draw-in groove of impressing through the mode of in-mould shaping in end button box injection moulding's in-process, rubber seal's front portion is inlayed and is established in the draw-in groove, rubber seal's lateral part and rear portion paste respectively and lean on the lateral wall and the back wall of shaft, just rubber seal's lateral part and rear portion are extruded the shaft with between the cell wall of mounting groove.

Description

Can promote binding post of waterproof performance

Technical Field

The utility model relates to a binding post technical field especially relates to a can promote binding post of waterproof performance.

Background

In the prior art, a watchcase of an electric meter is generally made of insulating plastics through an injection molding process, a connecting terminal is fixed on the watchcase, a circuit board inside the watchcase is connected with the connecting terminal through a cable and then connected with the outside through the connecting terminal, the connecting terminal is embedded on the watchcase, and the connecting terminal is generally made of copper. Because the environment that the watchcase was located is outdoor, and the environmental impact that expands with heat and contracts with cold is great, and the range of expanding with heat and contracting with cold is different between plastics watchcase and the binding post of copper, this will cause and can influence sealing performance because the change of environment produces the clearance between the two, and then reduces waterproof performance.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a can promote binding post of waterproof performance.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a can promote binding post of waterproof performance, has seted up a plurality of mounting grooves including the end button box on the end button box, inlays the terminal that is equipped with copper in the mounting groove, and the terminal includes the shaft, is formed with at least twice draw-in groove in the front of shaft the winding has rubber seal on the shaft, rubber seal's front portion inlays and establishes in the draw-in groove, rubber seal's lateral part and rear portion paste respectively and lean on the lateral wall and the back wall of shaft, and rubber seal's lateral part and rear portion are extruded the shaft with between the cell wall of mounting groove.

As an improvement of the utility model, the column body is provided with a mounting hole, a screw is arranged in the mounting hole in a penetrating way, and the column body is fixed on the terminal box through the screw

As a specific technical scheme of the utility model, the inside cavity of shaft is formed with the cavity.

As the utility model discloses a preferred, rubber seal is impressed in the draw-in groove through the mode of in-mould shaping at terminal button box injection moulding's in-process.

Compared with the prior art, the utility model has the advantages of: through establish the sealing washer on the shaft, under expend with heat and contract with cold's environment, when the clearance increase between shaft and the mounting groove cell wall of copper, the sealing washer inflation is in order to fill this clearance, and when the clearance between shaft and the mounting groove cell wall of copper reduced, the sealing washer can be compressed between the two because self elasticity, can ensure holistic leakproofness from this, promotes whole binding post's waterproof performance from this.

Drawings

Fig. 1 is a schematic view of an overall structure of a terminal box according to an embodiment of the present invention;

fig. 2 is a schematic structural view of the connection terminal in fig. 1.

Detailed Description

An embodiment of a terminal capable of improving waterproof performance of the present invention is further described with reference to fig. 1 to 2.

As shown in fig. 1-2, the present embodiment is a wiring terminal capable of improving waterproof performance, which includes a terminal box 1, a plurality of mounting grooves 2 are disposed on the terminal box 1, a copper wiring terminal 3 is embedded in the mounting grooves, the wiring terminal includes a shaft 4, a cavity is formed inside the shaft 4, the whole mass of the whole shaft 4 can be reduced by the design, and the light weight can be realized.

Two clamping grooves 5 which are arranged up and down are formed in the front face of the column body 4, a rubber sealing ring 6 is wound on the column body 4, and the rubber sealing ring 6 is pressed into the clamping grooves 5 in an in-mold forming mode in the injection molding process of the terminal button box 1. The front part of the rubber sealing ring 6 is embedded in the clamping groove 5, the side part and the rear part of the rubber sealing ring 6 are respectively attached to the side wall and the rear wall of the column body 4, and the side part and the rear part of the rubber sealing ring 6 are extruded between the column body 4 and the groove wall of the mounting groove 2.

The column body is provided with a mounting hole 7, a screw penetrates through the mounting hole 7, and the column body 4 is fixed on the terminal box 1 through the screw.

The above description is intended to illustrate the preferred embodiments of the present invention, and not to limit the scope of the invention, but also to provide the best mode of carrying out the invention.
