Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to an electrical connector with adjustable plugging height. Background Art

[0002] An electrical connector refers to a connection device between wires or conductor lines in a device, which is used to achieve smooth flow of current, connect two sub-electronic systems, and complete electrical connection. An electrical connector is also called a circuit connector or an electrical connector. It is a subdivision of electronic components and is mainly used for connection between circuits. Two matching connectors are used to connect metal terminal pieces to achieve electrical connection and conduction. The utility model with announcement number CN212626269U is a power socket adapter with adjustable height, which solves the problem that the power socket cannot be used because the user's hand cannot reach into the gap between the power socket and the bed or desk. The bottom of the socket is basically unobstructed, which does not affect the heat dissipation of the bottom, and the present invention has no scattered power cords, so it has good safety performance and is easy to use. In addition, the height of the present invention can be adjusted, and the card holder is connected to the power socket, which has dust-proof and waterproof effects.

[0003] The utility model with announcement number CN107369931B discloses a height-adjustable interface connector, which can achieve nine levels of adjustment at different heights, and a multi-level fixing unit of a connecting spring and a multi-level limiting unit of a supporting part are engaged with each other to fix them laterally to achieve the first adjustment of the height. The second height determination is achieved based on the cooperation between the multi-level supporting units on the supporting part and the circuit board, thereby effectively maintaining the direct contact area between the supporting units at each level and the circuit board.

[0004] However, the above-mentioned adjustable height electrical connector still has the following problems during actual use: although the plug-in connection in different situations is achieved through the variable height connector, this type of connector needs to be attached to the load-bearing element when adjusting the height, and the positioning achieved by the load-bearing element can determine the use height. At the same time, the metal terminals inside this type of connector can only extend the wires, and the stability of the connection and the locking position cannot be guaranteed during the contact conduction process. It is easy to fall off and separate due to external force after adjusting the height.

[0005] Therefore, we propose an electrical connector with adjustable plugging height to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide an electrical connector with adjustable plug-in height, in order to solve the problem that existing connectors with variable heights are used to achieve plug-in connections in different situations.
