Description

Technical Field

[0001] The utility model relates to an electrical connection plug assembly, in particular to a multi-layer spring sheet inter-plug type electrical connection plug assembly. Background Art

[0002] Electrical connectors play the role of physically connecting or disconnecting circuits in electrical systems. Electrical connection plug-in assemblies are the main components of mainstream electrical connectors (they can also be used directly as electrical connectors). In order to improve the reliability of electrical connections, reed-type electrical connection plug-in assemblies are becoming more and more widely used. In the sub-sectors of heavy loads and high currents (such as new energy vehicle charging connectors), reed-type electrical connection plug-in assemblies are usually used.

[0003] like Figure 1 As shown, a conventional spring-type electrical connection plug assembly generally includes two contact members, namely a socket 1 and a pin 2. A spring 11 is installed along the circumferential inner wall of the socket 1. The pin 2 is inserted into the socket 1 and the spring 11 is located between the pin 2 and the circumferential inner wall of the socket 1, thereby achieving reliable contact between the socket 1 and the pin 2 to meet the requirements of high current applications.

[0004] However, with the continuous development of industries such as new energy vehicles, the current-carrying capacity and safety requirements of electrical connectors are becoming increasingly higher, and the conductive performance of the above-mentioned traditional reed-type electrical connection plug-in components is still difficult to meet market demand. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-layer spring inter-insertion type electrical connection plug-in assembly with better conductive performance in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A multi-layer spring inter-plug-in electrical connection plug assembly includes a first contact piece and a second contact piece that are plug-connected to each other, and also includes a first spring piece and a second spring piece, wherein one end of the first contact piece is provided with a first plug hole, the first plug hole is provided with a first pin, the first spring piece is mounted on the circumferential inner wall of the first plug hole and in close contact, one end of the second contact piece is provided with a second pin, the second pin is provided with a second plug hole, the second spring piece is mounted on the circumferential inner wall of the second plug hole and in close contact, the second pin is placed in the first spring piece in the first plug hole and in close contact, and the first pin is placed in the second spring piece in the second plug hole and in close contact. On this basis, more plug holes and pins can be designed on the two contacts, and accordingly, more spring pieces can be provided.

[0008] Preferably, in order to achieve better conductivity, the first reed and the second reed are both connected to each other by a plurality of wavy metal elastic strips to form a cylindrical structure.

[0009] Preferably, in order to facilitate the connection of the wire, the other end of the first contact piece and the other end of the second contact piece are respectively provided with a welding cup for welding the wire.

[0010] The beneficial effects of the utility model are:

[0011] The utility model increases the contact points, enlarges the contact area, reduces the contact resistance, improves the conductivity, reduces the transmission loss, and meets the application requirements for the current carrying capacity and safety of the electrical connector, by designing a structure in which multiple plug holes and plug pins are inserted into each other and installing multiple layers of springs.
