technical field

The utility model relates to a cable connection device.

Background technique

In the current existing technology, the connection ends of the cables are usually connected by plug connectors, and there are usually fixed connections and detachable connections. After the fixed connection, the flexibility is limited, so most of them are connected by detachable plug connectors, but The plug joints in the prior art have the following problems: After multiple plugging and disassembly, the plug joints between them are not tight, and virtual connections are prone to occur. Potential safety hazard, there is also an industrial plug used for cable connection in the prior art, but this kind of plug is often complicated in structure and expensive, and is not suitable for civilian use in daily life.

Utility model content

The purpose of the utility model is to provide a cable plug joint, which can maintain the firm connection of the cable, and can maintain the stability and reliability of the cable connection after multiple insertions and disassembly.

In order to solve the problems of the technologies described above, the technical solution of the present invention is as follows:

A cable plug connector, including a female connector and a male connector, is characterized in that:

The female joint includes a cylindrical shell and a female ferrule. One end of the shell is closed, and an annular metal band is arranged on the closed end; the other end of the shell is an open end, and the female ferrule is arranged inside the shell through the open end. The female ferrule is provided with a socket hole, and the inner peripheral wall of the open end of the shell is provided with a plurality of strip-shaped protrusions, which clamp the female ferrule in the shell, and a strip-shaped protrusion is also provided on the inner peripheral wall. The groove, the ring-shaped metal band is connected with the ferrule;

The male joint includes a ring cover and a male ferrule, the outer end of the ring cover is fixedly connected with a second annular metal belt, and the inner end of the ring cover is fixedly connected with a male ferrule, the male ferrule is a columnar body, columnar There are multiple strip-shaped grooves and a strip-shaped protrusion on the side of the body. The strip-shaped grooves of the male joint correspond to the strip-shaped protrusions of the female joint. The strip-shaped protrusions of the male joint and the strip-shaped protrusions of the female joint Corresponding to the groove; the second annular metal belt is connected with the male ferrule;

The bottom end of the male ferrule is provided with a plug-in post, which corresponds to the plug-in hole of the female connector;

When plugging in, align the insertion post on the male connector with the insertion hole on the female connector and insert the male connector into the female connector. The strip-shaped protrusion on the female connector is stuck in the strip-shaped groove on the male connector. The strip-shaped protrusion on the top snaps into the strip-shaped groove of the female connector.

Both the male ferrule and the female ferrule are made of conductive materials.

Both the shell and the ring cover are made of insulating materials.

The present invention has following technical effect:

1. Simple structure, low cost, suitable for civilian use;

2. The connection is stable, and there are special clamping measures, so that the plug connector can still maintain the stability and reliability of the connection after multiple uses.
