Description

Technical Field

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

[0027] Example 1

[0028] like Figures 1-3 As shown, Figure 1 This is a three-dimensional structural diagram of the connecting terminals; Figure 2 This is a split view of the connection terminals; Figure 3 This is a cross-sectional view of the connection terminal. The connection terminal includes a rear sleeve 1, an inner sleeve 2, and a spring 3. The inner sleeve 2 is connected to the rear sleeve 1, and the spring 3 is located inside the inner cylinder. In use, current can be conducted between the rear sleeve 1, the inner sleeve 2, and the spring 3. The rear sleeve 1 is connected to the wire harness, and the external pin is inserted and contacts the spring 3.

[0029] Please refer to the following: Figure 4 and Figure 5 , Figure 4 for Figure 3 Enlarged view of part A in the image; Figure 5 This is a three-dimensional structural diagram of the rear sleeve 1. The rear sleeve 1 has a first insertion hole 11, which is opened along the axial direction of the rear sleeve 1, and the inner sleeve 2 is disposed within the first insertion hole 11. One end of the rear sleeve 1 also has a conductive layer 12, and the inner sleeve 2 has a conductive surface 22. When the inner sleeve 2 is connected to the rear sleeve 1, the conductive surface 22 of the inner sleeve 2 abuts against the conductive layer 12 of the rear sleeve 1. Specifically, the material used for the conductive layer 12 of the rear sleeve 1 is the same as the material used for the inner sleeve 2, thus avoiding electrochemical corrosion problems between different materials. In specific applications, the inner sleeve 2 is made of copper, the conductive layer 12 is also made of copper, and the overall structure of the rear sleeve 1 can be made of aluminum to reduce cost and weight. In this embodiment, copper is sprayed onto the end face of the rear sleeve 1 through a copper spraying process to form a conductive layer 12 made of copper.

[0030] Furthermore, the rear sleeve 1 also has a bearing surface 13, which is located inside the first insertion hole 11. When the inner sleeve 2 is installed in the rear sleeve 1, one end face of the inner sleeve 2 abuts against the bearing surface 13. The bearing surface 13 is used to support and limit the inner sleeve 2. Furthermore, the rear sleeve 1 also has a connecting plate 14, which is located at the end of the rear sleeve 1 away from the conductive layer 12. The connecting plate 14 is used to connect to the wire harness and conduct current. In this embodiment, the connecting plate 14 and the rear sleeve 1 are both made of the same material, such as aluminum, which effectively improves the connection effect between the wire harness and the connecting plate 14.

[0031] Please refer to the following: Figure 6 , Figure 6 This is a three-dimensional structural diagram of the inner sleeve 2. The inner sleeve 2 includes a support plate 23 and a support cylinder 24. The support cylinder 24 is connected to the support plate 23. One side of the support plate 23 is a conductive surface 22, which contacts the conductive layer 12 of the rear sleeve 1 during use. The support cylinder 24 is disposed in the first insertion hole 11, and the end face of the support cylinder 24 away from the support plate 23 abuts against the bearing surface 13. Specifically, the inner sleeve 2 also has a second insertion hole 21. The first insertion hole 11 passes through the support plate 23 and the support cylinder 24. The spring 3 is located in the second insertion hole 21 opened in the support cylinder 24. The external pin is inserted into the second insertion hole 21 and abuts against the spring 3.

[0032] In this embodiment, the reed 3 is made of a highly conductive and high-yield material, such as a spring.

[0033] In summary, by using the same material for the inner sleeve 2 and the conductive layer 12, it is possible to ensure that current can be conducted normally between the two, and to avoid electrochemical corrosion problems caused by the different materials of the inner sleeve 2 and the rear sleeve 1. In this way, the rear sleeve 1 can be made of low-cost and lightweight materials, such as aluminum, as needed, in order to reduce costs and weight.
