The utility model adopts a small angle fit, and the magnets on the top of the plug and the bottom of the jack are attracted to each other. Even a small suction force can make the contact pressure on the contact surface very large. The utility model has large contact surface, high pressure and small contact resistance. , Tight connection, fast plug-in and pull-out, easy to use.

Description

A magnetic suction type quick plug-in connector device

technical field

The utility model relates to a magnetic fast plug-in and pull-out joint device.

Background technique

In the current on-site electric power test, the secondary test wiring is standard-sized connectors and sockets, which are suitable for different test items of various professions. Generally, the joint part of the secondary test wiring adopts metal shrapnel or fastening screws to ensure the contact pressure of the connection between the secondary joint and the socket, so that the connection is fastened and reliable.

However, these two connection methods have problems such as easy damage, small contact pressure, unreliable connection, and easy disconnection of the connection point during the test, which affects the safety of the field test.

Utility model content

The technical problem solved by the utility model is to provide a magnetic quick plug-in connector device with large contact surface, high pressure, small contact resistance and fast connection.

The technical scheme of the utility model is as follows:

The utility model comprises a socket with a truncated conical plug with wires and a socket corresponding to the shape of the truncated conical plug, and the bottom of the socket and the top of the plug are provided with magnets with opposite polarities .

The positive effects of the utility model are as follows: the utility model is a magnetic fast plug-in connector device. When in use, the plug and the socket can be automatically sucked together so that the connection between them is firm and reliable. The utility model adopts a small angle fit According to the principle of mechanics, a very small suction force can make the contact pressure on the contact surface very large. The utility model has small contact resistance, quick insertion and removal, and convenient use.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model.

In the attached drawings: 1 socket, 2 plug, 3 wire, 4 jack.

Detailed ways

As shown in accompanying drawing 1, the utility model comprises the socket 1 that is provided with the plug 2 that has lead wire 3 of truncated cone shape, has the corresponding jack 4 of described truncated cone shape plug 2 shape, and described jack 4 The bottom of the plug 2 and the top of the plug 2 are provided with oppositely polarized magnets. The socket 4 is an oblique groove with an angle α of 100°, which can increase the contact area of the connection between the plug 2 and the socket 1, and can also increase the pressure on the contact surface after the two are attracted by the magnetic force, which can effectively reduce the contact Resistance, to meet the needs of field electrical professional test. When in use, the socket 1 with a magnet at the bottom of the jack 4 and the truncated conical plug 2 with a magnet on the top and the magnetic opposite to the bottom of the jack 4 are plugged together, the suction force is large, and the connection is firm. There is a secondary test at the tail of the plug 2 Wire 3. Under the action of the magnetic force of the magnet, the socket 1 and the plug 2 are automatically attracted and closed, which is fast and convenient for on-site use.

In the utility model, both the socket 1 and the plug 2 are made of metal, which can be used as a standard tool and popularized in various professional tests in the electric power industry. the
