Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically to a connector double-layer stacked terminal. Background Technology

[0002] Publicly available document (CN213184608U) discloses a three-layer structure male terminal for connectors, where the pin portion is composed of a continuous bottom layer, middle layer, and top layer, solving the problem of uneven thickness in the hollow center caused by a material thickness of 0.2mm. However, in practical applications, male terminals made of multi-layered laminated metal materials are prone to forking during long-term use, affecting the contact reliability of the connector and consequently the safety performance of the entire vehicle. Furthermore, the complex manufacturing process and high cost of existing male terminals limit their widespread application in fields such as new energy vehicles. Utility Model Content

[0003] The purpose of this invention is to solve the problem of forked joints that easily occur in mating terminals by improving the existing structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A connector double-layer stacked terminal includes an integrally formed pin portion, a mounting portion, and a crimping portion. The pin portion includes two overlapping metal sheets, and a snap-fit ​​structure is provided on the adjacent surfaces of the two metal sheets.

[0006] In the above technical solution, one end of the metal sheet is connected to the mounting part, and the other end of the metal sheet is suspended.

[0007] In the above technical solution, the two metal plates are symmetrically connected to the mounting part.

[0008] In the above technical solution, at least one metal sheet is provided with a protrusion, and the other metal sheet opposite to the protrusion is provided with a recess.

[0009] In the above technical solution, a transition section is provided between the metal sheet and the mounting part.

[0010] In the above technical solution, the transition section shown is an arc-shaped surface.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] The terminal structure of this solution can effectively enhance the rigidity of the male terminal and effectively solve the problem of forking that easily occurs during use due to the non-tight fit of metal materials or double-layer sheet structure, thereby improving the contact reliability of the connector and ensuring the driving safety of new energy vehicles.

[0013] The terminal structure of this solution is made of two pieces of metal material stacked together. The structure is reasonably designed, the manufacturing process is simple, the cost is low, and it has good application prospects.

[0014] This solution further improves the overall performance of the high-voltage connector through optimized terminal structure design, meeting the increasingly higher requirements of new energy vehicles for connectors. Attached Figure Description

[0015] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0016] Figure 1 This is a schematic diagram of the terminal unfolded structure;

[0017] Figure 2 This is a schematic diagram of the stacked molding structure;

[0018] Among them: 1 is the hook and loop fastener, 2 is the metal piece, 3 is the transition section, 4 is the mounting part, and 5 is the crimping part. Detailed Implementation

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 As shown, the terminal structure in this embodiment adopts an integral molding process, in which a metal sheet is cut into the corresponding shape to be crimped, and then crimped, forming the desired shape as shown. Figure 2 As shown.

[0022] The unfolded shape of the entire terminal structure includes two metal plates 2. One end of the metal plate 2 is connected to the mounting part 4, and the other end of the metal plate 2 is suspended. The two metal plates 2 are symmetrically arranged and both are connected to the mounting part 4. The rear end of the mounting part 4 is connected to the wire clamping part 5.

[0023] A latching structure 1 is provided on the metal sheet 2. The latching structure 1 includes a protrusion on at least one metal sheet 2 and a recess on the other metal sheet 2 at a position corresponding to the protrusion. When the two metal sheets 2 are stacked together, the protrusion is engaged with the recess, and the two metal sheets 2 are stacked as one. Figure 2 As shown. The two metal sheets can be made of copper alloy or other metals with good electrical conductivity and mechanical strength.

[0024] To ensure that the physical properties of the entire terminal are not damaged during the stacking process, a transition section 3 is provided between the metal sheet 2 and the mounting part 4. The transition section 3 eventually forms an arc-shaped surface structure during the stacking process to ensure the stress transfer from the pin part to the mounting part during the stacking process.

[0025] The pin section is used to insert into the female terminal of the connector, the mounting section is used to fix it to the housing of the male connector, and the crimping section is used to crimp the wire. The pin section is designed with a double or multi-layered sheet structure, and the snap-fit ​​structure of the pin section connects two adjacent metal pieces into a whole to prevent splitting.

[0026] In this embodiment, a metal strip is first stamped into two metal sheets using a stamping process. The two metal sheets are then stacked together, with several interlocking structures placed between any two adjacent layers. Finally, they are press-fitted into an integrated male terminal using a riveting process. This manufacturing process is simple and inexpensive.

[0027] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
