Description

TECHNICAL FIELD

[0001] The present application relates to the field of connectors, in particular to a connector with stable pins. BACKGROUND

[0002] In the application of connectors, some pins of female connectors need to be changed in direction, typically, for example, the refrigerator and air conditioner plugs against the wall, that is, the direction of the plug inserted into the socket is 90° bent with the direction of the wire. The bent pins are poor in stability and easy to shake due to the need to extend a long distance. CONTENT OF THE UTILITY MODEL

[0003] In order to improve the poor stability of the pins of the female connector which are bent to change the direction, the present application provides a connector with stable pins.

[0004] The present application provides a connector with stable pins, which adopts the following technical scheme:

[0005] A connector with stable pins comprises a male connector and a female connector which can be connected, a plurality of stable grooves are formed on the female connector, the stable grooves are used for the bent pins to enter, and the inner wall of the stable groove clamps the pins.

[0006] By clamping the bent pins by the inner wall of the stable groove, the stability of the pins is improved.

[0007] Optionally, a clamping groove and a clamping groove are formed on the side wall of the female connector in communication, a stable block and a connecting block are arranged on the male connector in connection, the opening surface of the clamping groove is smaller than that of the clamping groove, the cross-sectional diameter of the stable block is greater than the opening surface of the clamping groove, a guide inclined surface is formed on the stable block, the guide inclined surface is used for abutting against the inner wall of the clamping groove to guide the deformation of the side wall of the female connector to make room, and the stable block is inserted into the clamping groove through the clamping groove.

[0008] By adopting the above technical scheme, the stable block can be smoothly inserted into the clamping groove through the guide inclined surface, and then the stable block is abutted against by the smaller opening surface of the clamping groove. When the male connector is pulled out of the female connector under the influence of external force, the male connector is blocked, and the stability of the connection between the male connector and the female connector is improved.

[0009] Optionally, the clamping groove penetrates the side wall of the female connector.

[0010] By adopting the above technical scheme, the elastic force of the inner wall of the clamping groove is improved after being deformed by the abutment of the stable block, so that the insertion of the stable block is more smooth.

[0011] Optionally, a limiting groove is formed on the inner wall of the female connector, and a limiting strip is arranged on the male connector, the limiting strip is inserted into the limiting groove and slides, and the side wall of the limiting strip is attached to the inner wall of the limiting groove.

[0012] By adopting the above technical scheme, the process of inserting the male connector into the female connector is guided by the limiting strip and the limiting groove, and the insertion is smoother.

[0013] Optionally, the opening surface of the clamping groove is greater than the cross-sectional diameter of the connecting block, and the cross-sectional diameter of the clamping groove is greater than the cross-sectional diameter of the stabilizing block.

[0014] By adopting the above technical scheme, when the stabilizing block is inserted into the clamping groove, the inner wall of the clamping groove does not directly apply a clamping force to the stabilizing block, and the inner wall of the clamping groove does not directly apply an external force to the connecting block. Instead, the force of clamping the male connector by the female connector is transferred to the limiting strip, which protects the stabilizing block and reduces the probability of damage to the deformable structure.

[0015] Optionally, a yielding groove is further formed through the female connector, and the yielding groove and the clamping groove form a deformation block.

[0016] By adopting the above technical scheme, the deformation of the inner wall of the clamping groove is further facilitated, the elasticity is improved, and the stabilizing block is more easily inserted into the clamping groove.

[0017] Optionally, a spring strip is arranged between the inner walls of the clamping groove, and the spring strip stretches and stretches in the direction of moving the opposite inner walls of the clamping groove closer to each other.

[0018] By adopting the above technical scheme, the speed and shape of the clamping groove inner wall after deformation are improved by the spring strip, and the clamping groove inner wall can be reset after being deformed by the stabilizing block.

[0019] Optionally, a trigger groove is formed on the inner wall of the clamping groove, a rotating shaft is rotatably arranged in the trigger groove, an insertion block and a trigger block are arranged on the rotating shaft, a trigger rod is arranged on the spring strip, and an insertion groove is formed on the connecting block for the insertion of the insertion block. The trigger rod is used to drive the trigger block to rotate the rotating shaft.

[0020] By adopting the above technical scheme, the insertion block is inserted into the insertion groove by using the elastic force released when the clamping groove is reset and the spring strip is reset, and the stability of the male connector is further improved.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 1. Improve the stability of the pin.

[0023] 2. Further improve the stability of the male connector. BRIEF DESCRIPTION OF DRAWINGS
