Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connection terminal, connector, and charging socket. Background Technology

[0002] As a key component in electrical connections, connector terminals are typically assembled from multiple parts. In existing technologies, copper is commonly used to manufacture the components of connector terminals, primarily due to copper's excellent electrical conductivity. However, using copper as the manufacturing material has significant drawbacks: firstly, copper is expensive, leading to high overall manufacturing costs for connector terminals and hindering product competitiveness; secondly, copper has a high density, making it difficult to reduce the weight of connector terminals and failing to meet the current demand for lightweight equipment. With increasingly stringent requirements for cost reduction and lightweight connector terminals in the industrial sector, traditional copper-based manufacturing methods are no longer suitable for new application scenarios. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a connection terminal, a connector, and a charging base.

[0004] The present invention discloses a connecting terminal, comprising: a rear sleeve, a reel sleeve, and a support member. The reel sleeve has an insertion hole, one end of the rear sleeve is disposed in the insertion hole, and one end of the rear sleeve has a conductive layer that is in contact with the inner wall of the insertion hole. The support member is disposed on the outer surface of the end of the reel sleeve away from the rear sleeve. The conductive layer and the reel sleeve are made of the same material.

[0005] According to one embodiment of the present invention, the sleeve has a plurality of circumferentially spaced slots and forms a plurality of spring pieces, and a support member is disposed on the outer surface of the plurality of spring pieces.

[0006] According to one embodiment of the present invention, the spring has a contact surface protruding into the insertion hole.

[0007] According to one embodiment of the present invention, the support member is strip-shaped and is wound around the outer surface of the sleeve.

[0008] According to one embodiment of the present invention, the support member is sheet-shaped and is wound and stacked on the outer surface of the sleeve.

[0009] According to one embodiment of the present invention, the rear sleeve is made of aluminum.

[0010] According to one embodiment of the present invention, both the sheath and the conductive layer are made of copper.

[0011] According to one embodiment of the present invention, the sleeve is made of a material with high conductivity and high yield strength.

[0012] The present invention discloses a connector including the aforementioned connecting terminals.

[0013] The present invention discloses a charging dock, which includes the aforementioned connector.

[0014] The beneficial effect of this utility model is that the conductive layer on the back sleeve and the sleeve are designed to be made of the same material. When the back sleeve and the sleeve are made of different materials, the conductive layer is the main current conduction path. Since the conductive layer and the sleeve are made of the same material, electrochemical corrosion can be avoided when the back sleeve and the sleeve conduct current. The back sleeve can be made of low-cost and lightweight materials, ultimately achieving the effect of low cost and light weight of the connection terminal. Attached Figure Description

[0025] Example 1

[0026] like Figures 1-3 As shown, Figure 1 This is a three-dimensional structural diagram of the connecting terminals; Figure 2 This is a cross-sectional view of the connecting terminals; Figure 3 for Figure 2 Enlarged view of part A. The connecting terminal includes a rear sleeve 1, a reel sleeve 2, and a support member 3. The reel sleeve 2 is connected to the rear sleeve 1, and the support member 3 is disposed on the outer surface of the end of the reel sleeve 2 away from the rear sleeve 1. In use, the rear sleeve 1 is connected to other conductive components, and an external pin is inserted into the reel sleeve 2, so that current can be conducted between the external pin, the reel sleeve 2, the rear sleeve 1, and the conductive components.

[0027] One end of the rear sleeve 1 has a conductive layer 11, which is located on the outer surface of the rear sleeve 1 and abuts against the sleeve 2. Specifically, to reduce costs and the overall weight of the connection terminal, the rear sleeve 1 and the conductive layer 11 can be made of different materials. For example, the rear sleeve 1 can be made entirely of aluminum, while the conductive layer 11 can be made of the same material as the sleeve 2. In this embodiment, the sleeve 2 is made of copper, and correspondingly, the conductive layer 11 is also made of copper. Thus, the sleeve 2 is made of aluminum, which has the advantages of lower cost and lighter weight compared to copper. Current is conducted between the rear sleeve 1 and the sleeve 2 through the conductive layer 11. Since the conductive layer 11 and the sleeve 2 are made of the same material, electrochemical corrosion between them can be avoided. In practical applications, the conductive layer 11 is sprayed onto the end of the rear sleeve 1 using an existing copper spraying process.

[0028] The sleeve 2 has a socket 21, which is opened along the length of the sleeve 2. One end of the rear sleeve 1 is inserted into the socket 21, and the conductive layer 11 of the rear sleeve 1 abuts against the inner wall of the socket 21 to facilitate current conduction. Furthermore, the sleeve 2 has a plurality of slots 22 at the end away from the rear sleeve 1. The plurality of slots are opened around the outer surface of the sleeve 2, and the plurality of slots 22 are spaced apart. The opening of the plurality of slots 22 will form a plurality of spring pieces 23. The support member 3 is disposed on the outer surface of the plurality of spring pieces 23, and the support member 3 supports the plurality of spring pieces 23. Furthermore, the spring contacts 23 have contact surfaces 231 that protrude into the socket 21. When an external pin is inserted, the contact surfaces 231 on multiple spring contacts 23 abut against the surface of the external pin. Under the pressure of the external pin, the multiple spring contacts 23 expand outwards. The support member 3 supports the spring contacts 23 to increase the positive force between the spring contacts 23 and the external pin, thereby improving the current conduction effect. In this embodiment, the sleeve 2 is made of a material with high conductivity and high yield strength.

[0029] The support member 3 has a strip-like structure. In use, the support member 3 is sequentially wound around the outer surface of multiple spring pieces 23 from top to bottom, and the winding position of the support member 3 corresponds to the position of the contact surface 231. Alternatively, the support member 3 can also have a sheet-like structure, i.e., its longitudinal section is rectangular. The support member 3 is wound and stacked on the outer surface of multiple spring pieces 23. Since the single-layer structure of the support member 3 provides limited support for the spring pieces 23 and is inconvenient to adjust, it is necessary to increase the support force and improve the ease of adjustment by overlapping. In this embodiment, the support member 3 is made of an elastic material.

[0030] In summary, by designing the conductive layer 11 on the back sleeve 1 and the sleeve 2 to be made of the same material, when the back sleeve 1 and the sleeve 2 are made of different materials, the conductive layer 11 is the main current conduction path. Since the conductive layer 11 and the sleeve 2 are made of the same material, electrochemical corrosion can be avoided when the back sleeve 1 and the sleeve 2 conduct current. The back sleeve 1 can be made of a low-cost and lightweight material, ultimately achieving the effect of low cost and light weight for the connection terminal.
