Connecting device

Technical Field

The invention relates to the field of plugging equipment, in particular to a connecting device.

Background

After the plug in the existing straight-insertion rectangular connector is inserted into the socket, the plug is pulled out manually only by a person, so that the plug and the socket are quite difficult to separate. Especially in the case of connectors installed in a narrow space, it is very inconvenient to withdraw the plug. Moreover, when people pull out the plug, the deformation of the connector contact piece is easily caused once the plug is inclined by force, so that the product is damaged and the service performance of the product is affected.

The lower end of the hook is hinged with the accommodating groove, and the upper end of the hook is arranged in the annular groove.

According to the invention, after an operator inserts the plug into the slot, the plug applies pressure to the blocking part, so that the sliding blocks at the two ends of the shell pull the reset spring to move downwards simultaneously, the hook moves upwards to the top end of the annular groove along the annular groove when the sliding blocks move downwards, and after the plug is contacted with the contact piece, the operator releases hands, the reset spring pulls the sliding blocks to move upwards, the annular groove moves upwards, and the upper end of the hook is fixed on the fixed block. When the operator continues to push the plug to enable the upper end of the hook to slide out of the fixed block and then loosen the hand, the reset spring pulls the sliding block and the plug to move upwards, and separation of the plug and the contact piece is achieved.

Preferably, the annular groove comprises a fixing groove arranged at the upper end of the fixing block, a reset groove arranged at one side of the fixing groove and a plugging groove arranged at the other side of the fixing groove.

According to the invention, the upper end of the hook is moved into the fixed groove through the inserting groove, and the upper end of the hook is reset to the initial position from the fixed groove through the reset groove.

Preferably, a V-shaped block is provided above the fixing groove.

According to the invention, the hook is extruded into the reset groove from the fixing groove through the V-shaped block.

Preferably, the annular groove is provided with a baffle.

The hook is limited in the annular groove through the baffle plate.

Preferably, the sliding part is provided with a sliding rail, and the shell is provided with a sliding table matched with the sliding rail.

Preferably, chamfer angles are arranged at two ends of the hook.

Preferably, the surface of the slider is treated by electroplating

The invention improves the wear resistance and corrosion resistance of the sliding block by electroplating the surface of the sliding block.

Preferably, the surface of the return spring is subjected to an electroplating process.

The invention improves the wear resistance and corrosion resistance of the return spring by electroplating the surface of the return spring.

The invention has the following beneficial effects:

according to the invention, the plug is pressed down by an operator for the first time, so that the hook moves from the upper end of the annular groove to the fixed block and is fixed in the fixed block, the connection and fixation between the plug and the socket are realized, the plug is pressed down for the second time, so that the hook is reset from the fixed block to the bottom end of the annular groove, the separation between the plug and the socket is realized, the situation that the plug is pulled by the operator forcefully and the socket is damaged when the insertion force and the separation force between the socket and the plug are large is avoided, the structure is simple, the operation is convenient, and the usability of a product is improved.

Detailed Description

The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.

Examples

Referring to fig. 1 to 7, the present invention includes a plug 1 and a socket 2 for connecting the plug 1, the socket 2 includes a housing 21 and a socket 22 provided in the housing 21 for receiving the plug 1, and a contact 23 for connecting the socket 2 and conducting electricity is provided at a bottom end of the socket 22.

With further reference to fig. 1 to 3, the housing 21 is provided with accommodating grooves 24 at two ends of the slot 22, the accommodating grooves 24 are provided with sliding blocks 3 which can slide along the accommodating grooves 24, the accommodating grooves 24 are provided with reset springs 4 at the upper ends of the sliding blocks 3, and two ends of the reset springs 4 are respectively connected with the sliding blocks 3 and the accommodating grooves 24.

A hook 5 is arranged in the accommodating groove 24 and positioned at the lower end of the sliding block 3, and chamfer angles 51 are arranged at two ends of the hook 5.
