Abstract

The utility model discloses a waterproof wiring mouth of terminal box is equipped with a plurality of wiring mouths on the terminal box, all be equipped with waterproofing mechanism on a plurality of wiring mouths, waterproofing mechanism includes external tapping nut, internal tapping nut, the external tapping nut passes through threaded connection on the wiring mouth in the terminal box outside, and external tapping nut tip is connected with the terminal box lateral wall, and the internal tapping nut passes through threaded connection on the inboard wiring mouth of terminal box, and internal tapping nut tip is connected with the terminal box inside wall. This waterproof wiring mouth simple structure, convenient to use has increased the wiring mouth water-proof effects of external tapping nut, internal joint nut better.

Description

The waterproof wiring mouth of terminal box

Technical field

The utility model belongs to connection jaws, is specifically related to a kind of waterproof wiring mouth of terminal box.

Background technology

The waterproof junction box connection jaws place using at present generally only has an interface nut, is difficult for fixed cable, and easily loosening, only, by screwing screw fixed cable, waterproof effect is poor.

Summary of the invention

The problems referred to above that exist in order to overcome prior art field, the purpose of this utility model is, a kind of waterproof wiring mouth of terminal box is provided, and solves the poor problem of connection jaws waterproof effect in current terminal box.

The waterproof wiring mouth of the terminal box that the utility model provides, terminal box is provided with some connection jaws, on described some connection jaws, be equipped with proof mechanism of water, described proof mechanism of water comprises external tapping nut, inner joint nut, described external tapping nut is threaded connection on the connection jaws in terminal box outside, and external tapping nut end is connected with terminal box lateral wall, inner joint nut is threaded connection on the connection jaws of terminal box inner side, and inner joint nut end is connected with terminal box madial wall.

It also comprises rubber fastening band, and described rubber fastening band is arranged on connection jaws.

The waterproof wiring mouth of the terminal box that the utility model provides, its beneficial effect is, and this waterproof wiring mouth structure is simple, easy to use, and the connection jaws waterproof effect that has increased external tapping nut, inner joint nut is better.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of the utility model embodiment;

Fig. 2 is the structural representation of the utility model embodiment connection jaws.

In figure, mark:

1. connection jaws; 2. external tapping nut; 3. inner joint nut.

Embodiment

With reference to the accompanying drawings, in conjunction with the embodiments, the waterproof wiring mouth of the terminal box that the utility model is provided, is described in detail.

Embodiment

With reference to Fig. 1-Fig. 2, the waterproof wiring mouth of the terminal box of the present embodiment, terminal box is provided with some connection jaws 1, on described some connection jaws 1, be equipped with proof mechanism of water, described proof mechanism of water comprises external tapping nut 2, inner joint nut 3, described external tapping nut 2 is threaded connection on the connection jaws 1 in terminal box outside, and external tapping nut 2 ends are connected with terminal box lateral wall, inner joint nut 3 is threaded connection on the connection jaws 1 of terminal box inner side, and inner joint nut 3 ends are connected with terminal box madial wall.

It also comprises rubber fastening band, and described rubber fastening band is arranged on connection jaws 1.

Use external tapping nut 2, the inner joint nut 3 on the one hand can more effective waterproof, on the other hand can fixed cable, be arranged on the character that external tapping nut 2, inner joint nut 3 rubber fastening band above has water-swellable, and there is larger elasticity, screw external tapping nut 2, inner joint nut 3 can make the gap between rubber fastening band and cable closely knit, and fixed cable.
