Description

A wire connector

technical field

The utility model relates to a joint, in particular to a connection joint between an input wire of an electric device and an external power supply wire.

Background technique

Electrical equipment is driven by electricity, which must be connected to an external power supply through a wire connection joint. The commonly used connection joint between the input wire of electrical equipment and the external power supply wire is composed of a male connector and a female connector. A male terminal and a female terminal that cooperate with each other are arranged in the joint. The connecting joints currently used have disadvantages such as poor sealing effect, poor waterproof performance of the joint, easy disengagement between the male joint and the female joint, and easy falling off of the metal parts in the joint.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a wire connection joint with good sealing effect, good waterproof performance of the joint, difficult to disengage between the male joint and the female joint, and the metal parts in the joint are not easy to fall off.

The technical scheme that the utility model solves its technical problem adopts is:

A wire connection joint, including a male joint and a female joint, characterized in that the male joint includes a male terminal, a male terminal body for fixing the male terminal, an injection inner core and an injection jacket, and the female joint includes a female terminal, a fixed female terminal The body of the female terminal, the injection inner core and the injection jacket, the male connector is provided with a threaded connector, and the female connector is covered with a nut that matches the threaded connector on the male connector.

A waterproof sealing ring is set on the above-mentioned female terminal body.

As an improvement of the above technical solution of the present invention, the side wall of the female terminal body is provided with a guide groove, and the inner wall of the male joint body is provided with a guide block matching with the guide groove.

The beneficial effect of the utility model is: the utility model fixes the male terminal and the female terminal in the male terminal body and the female terminal body respectively by injection molding, so the sealing effect is good, and the metal terminal in the joint can be prevented from falling off; at the same time When the male joint and the female joint are assembled together, they can be fixed by threaded connectors and nuts, so as to prevent the male joint and the female joint from being disengaged; and a waterproof sealing gasket is installed on the female joint, thereby preventing water from connecting the two joints. Infiltrated to ensure that the utility model has good waterproof performance.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a three-dimensional exploded schematic diagram of the utility model.

Detailed ways

Referring to Fig. 1, a wire connection joint disclosed by the utility model includes a male joint 1 and a female joint 2, wherein the male joint 1 includes a male terminal 11, a male terminal body 12 for fixing the male terminal 11, an injection inner core 13 and an injection jacket 14. The female joint 2 includes a female terminal 21, a female terminal body 22 for fixing the female terminal 21, an injection inner core 23 and an injection jacket 24. The utility model has the characteristics of good sealing effect and can prevent the metal terminals in the joint from falling off.

A threaded connecting piece 15 is provided on the male joint 1, and a nut 25 matching the threaded connecting piece 15 on the male joint 1 is set on the female joint 2. When the male joint 1 and the female joint 2 are assembled together, the It is fixed by the threaded connecting piece 15 and the nut 25, so that the male joint and the female joint can be prevented from being disengaged.

As shown in the figure, a waterproof sealing ring 26 is set on the female terminal body 22, so as to prevent water from infiltrating from the connection of the two joints, so as to ensure that the utility model has good waterproof performance.

The side wall of the female terminal body 22 is provided with a guide groove 27, and the inner wall of the male connector body 12 is provided with a guide block (not shown) matching with the guide groove 27, so as to facilitate the insertion of the utility model.
