[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figures 1 to 2 As shown, a pluggable high-current connector of this utility model includes a board end bracket 1, a wire end bracket 2, at least one end bending pin 3, and at least one wire end PIN pin 4.

[0033] The plate end bending pin 3 is fixed to the plate end bracket 1;

[0034] One end of the plate end bracket 1 is provided with a connecting groove 11;

[0035] One end of the plate end bending pin 3 is provided with an elastic abutment pin 31, which is exposed in the connecting groove 11;

[0036] The wire end bracket 2 is provided with a connecting part 21;

[0037] The wire end PIN pin 4 is fixed to the wire end bracket 2;

[0038] One end of the PIN pin 4 is provided with a conductive connecting tube 41, which is fixed inside the connecting part 21;

[0039] The wire end bracket 2 is connected to the connecting groove 11 of the plate end bracket 1 via the connecting part 21, and the elastic abutment pin 31 is connected to the conductive connecting cylinder 41.

[0040] Specifically, the wire end bracket 2 and the plate end bracket 1 are connected by the cooperation of the connecting part 21 and the connecting groove 11, which is easy to operate; at the same time, the connection method between the elastic abutment pin 31 and the conductive connecting cylinder 41 utilizes the elasticity of the elastic abutment pin 31 to ensure that the two always maintain a tight and stable electrical contact during insertion, removal and long-term use, avoiding poor contact due to vibration, loosening and other reasons, and ensuring the reliability of high current transmission.

[0041] The connector structure of this application is reasonably designed and the layout of each component is compact. The board end bracket 1 and the wire end bracket 2 cooperate through a specific connection method to realize the high current connection function in a limited space, which is suitable for electronic equipment installation scenarios with strict space requirements.

[0042] When the connector malfunctions or needs to be replaced, thanks to the plug-in design, maintenance or replacement can be easily performed by simply unplugging the wire end bracket 2 from the board end bracket 1, without having to disassemble the entire device on a large scale, thus reducing maintenance costs and time.

[0043] When the wire end bracket 2 is connected to the connecting groove 11 of the plate end bracket 1 via the connecting part 21, the elastic abutment pin 31 contacts the conductive connecting cylinder 41, thereby establishing an electrical path and realizing stable transmission of large current. This structural design cleverly utilizes the elastic characteristics of the elastic abutment pin 31 to ensure a reliable electrical connection during insertion and removal as well as during use, while also facilitating insertion and removal operations.

[0044] like Figure 1 As shown, in this embodiment, the end of the plate end bracket 1 facing away from the connecting groove 11 is provided with an injection groove 12, and a partition hole 13 is provided on one side of the injection groove 12. The plate end bending needle 3 is restricted to the partition hole 13.

[0045] Specifically, the glue injection groove 12 provided by the board end bracket 1 provides space for subsequent glue injection, fixing and sealing operations, thereby enhancing the fixation and protection of the connector and improving its stability and reliability.

[0046] The position of the bending pin 3 at the end of the plate is restricted and positioned by the partition hole 13 to prevent the bending pin from deviating, ensure accurate and stable electrical connection, and solve the problem of poor contact.

[0047] The bending pin 3 at the end of the plate is constrained by the partition hole 13, which ensures the accurate position of the bending pin, improves the reliability of the plug-in connection, and facilitates miniaturization and compact design.

[0048] like Figure 2As shown, the plate end bending needle 3 of this embodiment includes an integrally formed bending part 301, a limiting part 302, and a fixing part 303.

[0049] The bending part 301 is restricted to the partition hole 13, the limiting part 302 abuts against the glue injection groove 12, a fixing hole 14 is provided between the connecting groove 11 and the glue injection groove 12, the fixing part 303 is provided in the fixing hole 14, and the fixing part 303 is provided with a glue-containing groove 304.

[0050] One end of the fixed part 303 extending out of the fixed hole 14 is connected to the elastic abutment pin 31.

[0051] Specifically, the integrally formed bending part 301, limiting part 302 and fixing part 303 make the various parts of the plate end bending needle 3 seamlessly connected into an integral structure, improving the needle body strength and electrical conductivity stability, and avoiding poor contact due to loose structure.

[0052] The partition hole 13 constrains the position of the bending part 301, enabling precise positioning of the bending pin 3 at the end of the plate, ensuring accurate electrical connection during insertion and removal, and solving the problem of loose contact.

[0053] The limiting part 302 contacts and limits the needle body by contacting the glue injection groove 12, which prevents excessive displacement of the needle body, ensures stable connection, and facilitates compact design.

[0054] By providing a glue-containing groove 304 in the fixing hole 14 through the fixing part 303, the glue-containing groove 304 stores glue to strengthen the connection between the fixing part 303 and the inner wall of the fixing hole 14, thereby improving reliability.

[0055] The fixed connection part 303 is connected to the elastic abutment pin 31. The fixed connection part 303 acts as a connecting bridge to stably conduct current and ensure reliable transmission of large current.

[0056] like Figure 1 As shown, in this embodiment, a glue injector 15 is provided in the glue injection groove 12, and the glue injector 15 is connected to the plate end bending pin 3.

[0057] Specifically, the adhesive fastener 15 fills the space of the glue injection groove 12 to strengthen the fixation of the bending pin 3 at the end of the board, prevent it from shaking or shifting, ensure stable electrical connection, and solve the problem of poor contact. In actual use, the adhesive fastener 15 is formed by curing adhesive, such as epoxy resin adhesive, polyurethane adhesive, or acrylic adhesive.

[0058] like Figure 2 As shown, the elastic abutment pin 31 of this embodiment includes at least two elastic bodies 311, and a deformation space 312 is provided between the two elastic bodies 311.

[0059] Specifically, the main body of the elastic abutment needle 31 is formed by combining at least two elastic bodies 311, which increases the number of contact points with the conductive connecting cylinder 41, disperses the current, enhances the stability of high current transmission, and solves the problem of unstable contact of a single elastic body 311.

[0060] The deformation space 312 provides a buffer for the elastic body 311 under pressure deformation, ensuring that the elastic body 311 deforms reasonably during insertion, removal and use, and always fits tightly against the conductive connecting cylinder 41, improving the reliability of electrical connection and helping to cope with vibration and other working conditions.

[0061] like Figure 1 As shown, in this embodiment, the end of the line end bracket 2 corresponding to the end of the connecting part 21 is provided with a limiting step 22 for abutting against the plate end bracket 1.

[0062] Specifically, the limiting step 22 acts as a physical blocking structure, forming a stop reference with the contact surface of the board end bracket 1. The limiting step 22 precisely limits the insertion and removal positions of the line end bracket 2 and the board end bracket 1, avoiding excessive insertion and removal that could damage components, ensuring the stability of the electrical connection, and solving the problem of difficulty in controlling the insertion and removal depth.

[0063] like Figure 1 As shown, the wire end bracket 2 of this embodiment is provided with a mounting groove 23 that passes through the connecting part 21, and the conductive connecting cylinder 41 is fixed in the mounting groove 23.

[0064] Specifically, the mounting groove 23 provides space for accommodating and fixing the conductive connecting cylinder 41, and its through-hole design facilitates electrical connection layout. Precise positioning of the conductive connecting cylinder 41 within the mounting groove 23 ensures reliable connection between it and the elastic abutment pin 31, improving the stability of high-current transmission and facilitating compact connector design.

[0065] like Figure 1 As shown, in this embodiment, the wire end PIN pin 4 is provided with a limiting ring 42, the mounting groove 23 is provided with a recessed groove 24, and the limiting ring 42 is disposed in the recessed groove 24.

[0066] Specifically, the limiting ring 42 cooperates with the sinking groove 24 to prevent the wire end PIN pin 4 from moving axially within the mounting groove 23, ensuring the stability of the position of the wire end PIN pin 4 and the conductive connecting cylinder 41, ensuring the reliability of the electrical connection, and solving the problem of poor contact caused by PIN pin displacement.

[0067] like Figure 1 As shown, the end of the conductive connecting cylinder 41 in this embodiment is provided with an inlet bevel 411, which is used to guide the elastic abutment pin 31 into the interior of the conductive connecting cylinder 41.

[0068] Specifically, by introducing the bevel 411, the difficulty of inserting the elastic abutment pin 31 into the conductive connecting cylinder 41 is reduced, collision wear is reduced, smooth docking is ensured, insertion and removal efficiency and electrical connection stability are improved, and the problem of misalignment leading to insertion failure is solved.

[0069] like Figure 1 As shown, in this embodiment, a guide block 16 is provided in the connecting groove 11, and a guide groove 25 is provided in the connecting part 21.

[0070] When the connecting part 21 is connected to the connecting groove 11, the guide block 16 slides along the guide groove 25.

[0071] Specifically, the guide block 16 serves as a directional guide component, and the guide groove 25 limits the sliding trajectory of the guide block 16, constraining the movement range of the connecting part 21. This ensures a precise fit between the connecting part 21 and the connecting groove 11, improving the smoothness of insertion and removal, enhancing connection stability, and facilitating efficient and reliable electrical connections.

[0072] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
