Description

Slim charging connector

Technical Field

The utility model relates to the field of medical equipment control, in particular to a slim charging connector for electric wheelchair.

Background

The electric wheelchair is formed by modifying and upgrading components such as a superposed power driving device, an intelligent operating device, a battery and the like on the basis of the traditional manual wheelchair. The existing charging connector is connected with a frame of a wheelchair in a clamping manner, and the clamping block is arranged on the circumference of the charging seat, so that the thickness of the charging head can be increased in order to increase the stability of the charging head, and the contact between the clamping block and the clamping groove is increased; the joint lead wire of head rear end that charges generally extends to the rear, has further led to the increase of the whole thickness of charging joint head to occupy great wheelchair automobile body space, can not adapt to the needs of the production frivolousization of wheelchair.

SUMMERY OF THE UTILITY MODEL

The utility model provides a slim charging connector to the needs that charging connector thickness is great among the prior art, can not adapt to the frivolous production of wheelchair.

The technical scheme is as follows:

a thin charging connector comprises a shell, wherein the shell comprises a front shell and a rear end cover; the front end face of the front shell is respectively provided with a USB (universal serial bus) socket and a three-hole power socket, the front end face is also provided with a connecting hole, and the upper side and the lower side of the rear end face of the front shell are provided with a wire slot A and a wire slot B which are used for leading wires in the upward direction and the downward direction; the rear end cover comprises a connector A and a connector B which are used for sealing a USB socket and a three-hole power socket, and further comprises a shell surface used for sealing a wire slot.

Further: the connecting holes comprise a connecting hole A and a connecting hole B which are respectively arranged on the upper side and the lower side of the front end surface of the front shell.

Further: and elastic terminals are arranged in the jacks of the three-hole power socket, and the shapes of the jacks are matched with the elastic terminals.

Further: and the wiring end of the elastic terminal is connected with the lead wire in a cold pressing mode.

Further: the elastic terminal is a vase terminal.

Has the advantages that:

1. the rear end face of the front shell of the charging head shell is provided with a wire groove for leading wires to the upper side and the lower side, so that the thickness of the charging head can be reduced, the front end face of the front shell is provided with a connecting hole, the shell is connected in a screw, screw or rivet mode through clamping, and the space required by the charging head is further reduced;

2. the upper side and the lower side of the front end surface of the front shell are respectively provided with a connecting hole, so that the connecting stability can be ensured;

3. the elastic terminal is arranged in the jack of the three-hole power socket, the shape of the jack is matched with that of the elastic terminal, so that the elastic terminal can be tightly fixed without shaking, the elastic terminal can still ensure the tight insertion after being inserted for many times, and the practical service life is prolonged;

4. the wiring end of the elastic terminal is connected with the lead wire in a cold pressing mode, so that the connection strength can be enhanced, and compared with welding, the current carrying capacity is increased, and the service life is prolonged.
