Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a solderless quick-connect terminal. Background Technology

[0002] In the field of electrical connections, traditional wire connections often employ welding, a method with numerous drawbacks. Welding requires specialized equipment and tools, is complex, and demands high skill levels from operators. Operators must not only master welding parameters such as temperature and time but also possess proficient operating techniques; otherwise, weak welds or incomplete solder joints can easily occur, affecting the quality of the wire connection. Furthermore, the high temperatures generated during welding can damage the insulation material surrounding the wire, reducing its insulation performance and increasing safety hazards. In addition, welded wire connections are difficult to disassemble and replace. Repairing or replacing the wire often requires destroying the weld and re-welding, increasing maintenance costs and wasting time and manpower.

[0003] Besides soldering, some connectors use screws for fixing, but this method also has problems. Screw fixing requires tools such as screwdrivers, which is inconvenient, and the screws are prone to loosening during frequent disassembly and installation, leading to poor contact and affecting the stability of the wire connection. Furthermore, screw fixing is not secure enough for the wire; when subjected to external force, the wire can easily detach from the connector, causing circuit failure. Therefore, a connector that can quickly, conveniently, and securely connect wires is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for specialized welding equipment and tools, complex operation processes, and high skill requirements for operators, by proposing a welding-free quick-connect terminal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solderless quick-connect terminal includes a terminal body, a first groove formed in the terminal body, an electrical connection plate fixed in the terminal body, and a connecting groove connected to the first groove formed on the side end of the terminal body. The connecting groove is used for inserting a power supply wire. In order to facilitate the positioning of the inserted wire, a set of elastic positioning components is provided in the terminal body. The elastic positioning components are used to limit the position of the wire.

[0007] To facilitate the driving of the elastic positioning component, a second groove is provided in the terminal body. A connecting rod for pressing the elastic positioning component slides in the second groove. A set of limiting components is provided in the connecting rod to position the connecting rod so that the connecting rod cannot be pressed.

[0008] In one possible design, the elastic positioning component includes a third groove formed within the terminal body, the third groove being connected to a second groove and a first groove respectively, a connecting plate sliding within the third groove, a clamping plate fixed to the bottom end of the connecting plate, the clamping plate extending downward into the first groove, a slot formed within the clamping plate for a power supply wire to pass through, the connecting plate sliding within the slot, a receiving groove formed within the terminal body communicating with the third groove, a spring sheet fixed within the receiving groove, the other end of the spring sheet abutting against the bottom end of the connecting plate, and a connecting rod fixed to the top end of the connecting plate;

[0009] The process involves pressing the connecting rod to move the connecting plate downwards, which in turn moves the clamping plate downwards. The clamping plate then moves the slot downwards to maintain alignment and connection with the connecting groove. At this point, an electrical wire is inserted, passing through both the connecting groove and the slot. The connecting rod is then released, causing the spring plate to push the connecting plate upwards. This, in turn, moves the clamping plate upwards, allowing the inner wall of the clamping plate to work in conjunction with the electrical connecting plate to hold and fix the electrical wire, thus facilitating its secure installation.

[0010] In one possible design, there are two clamping plates, which are located on both sides of the bottom end of the connecting plate.

[0011] In one possible design, the inner walls of both slots are fixed with multiple inclined plates, the orientation of which is opposite to the direction of entry of the wires.

[0012] One feature is that it allows the wire to enter easily, making it impossible to pull the clamped wire out directly.

[0013] In one possible design, the limiting component includes a threaded groove formed at the top of the connecting rod, a threaded rod threadedly connected in the threaded groove, and a limiting plate fixed at the top of the threaded rod.

[0014] In this process, by twisting the limiting plate, the threaded rod moves in the threaded groove, thereby adjusting the position of the limiting plate. After the spring plate pushes the connecting plate upward, twisting the limiting plate downward can lock the position of the connecting plate, thereby further enhancing the positioning of the spring plate.

[0015] In one possible design, the surface of the limiting plate is provided with an anti-slip ring.

[0016] In one possible design, both the connecting plate and the connecting rod are made of insulating plastic.

[0017] In this application, pressing the connecting rod causes the connecting plate to move downward, the connecting plate causes the clamping plate to move downward, and the clamping plate causes the slot to move downward to maintain alignment and communication with the connecting groove. At this time, the wire is inserted, and after the wire passes through the connecting groove and the slot, the connecting rod is released, so that the elasticity of the spring plate pushes the connecting plate upward, causing the connecting plate to move the clamping plate upward. Thus, the inner wall of the clamping plate, together with the electric connecting plate, clamps and fixes the wire, making it convenient to fix the wire.

[0018] By turning the limiting plate, the threaded rod moves in the threaded groove, thereby adjusting the position of the limiting plate. After the spring plate pushes the connecting plate upward, turning the limiting plate downward can lock the position of the connecting plate, thereby further enhancing the positioning of the spring plate.

[0019] Beneficial effects:

[0020] In this utility model, a solderless quick-connect terminal is provided. This solderless quick-connect terminal has a through groove in the terminal body, which facilitates the direct insertion of wires. With the cooperation of the elastic positioning component and the electrical connection plate, the wires can be clamped and fixed simply by pressing and releasing the connecting rod. There is no need for complicated welding or screw fixing operations, which greatly saves connection time and improves work efficiency.

[0021] In this invention, the solderless quick-connect terminal utilizes a spring plate in its elastic positioning assembly to provide stable elastic force, ensuring a tight fit between the clamping plate and the electrical connection plate, firmly holding the wire in place. Simultaneously, the inclined clamping plate within the slot further enhances the clamping effect, preventing the wire from detaching under external pulling force, thus guaranteeing the stability and reliability of the wire connection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The connecting groove 15 is used for the insertion of power supply lines.

[0029] A set of elastic positioning components is provided inside the terminal body 1. The elastic positioning components include a third groove 7 formed inside the terminal body 1, which is connected to the second groove 5 and the first groove 3. A connecting plate 8 slides inside the third groove 7, and a clamping plate 9 is fixed to the bottom end of the connecting plate 8, extending downward into the first groove 3. A slot 10 is formed inside the clamping plate 9 for the power supply wire to pass through, and an electrical connecting plate 14 is slidably disposed in the slot 10. A receiving groove 11 connected to the third groove 7 is formed inside the terminal body 1, and a spring sheet 12 is fixed inside the receiving groove 11, with the other end of the spring sheet 12 abutting against the bottom end of the connecting plate 8.

[0030] In this embodiment, there are two clamping plates 9, which are located on both sides of the bottom end of the connecting plate 8. Multiple inclined clamping plates 13 are fixed on the inner walls of the two slots 10. The orientation of the multiple inclined clamping plates 13 is opposite to the direction of the wire entry, which facilitates the entry of the wire and prevents the clamped wire from being pulled out directly.

[0031] To facilitate the driving of the elastic positioning component, a second groove 5 is provided in the terminal body 1. A connecting rod 6 for pressing the elastic positioning component slides in the second groove 5. The connecting rod 6 is fixed to the top of the connecting plate 8.

[0032] In another embodiment: Refer to Figures 1-4 An improvement based on embodiment 1: A set of limiting components is provided inside the connecting rod 6. The limiting components include a threaded groove opened at the top of the connecting rod 6, a threaded rod 4 is threadedly connected in the threaded groove, a limiting plate 2 is fixed at the top of the threaded rod 4, and an anti-slip ring is provided on the surface of the limiting plate 2.

[0033] In actual operation, pressing the connecting rod 6 causes the connecting plate 8 to move downwards, which in turn causes the clamping plate 9 to move downwards. The clamping plate 9 then causes the slot 10 to move downwards, maintaining alignment and communication with the connecting groove 15. At this point, a wire is inserted, passing through the connecting groove 15 and the slot 10. Releasing the connecting rod 6 then allows the elasticity of the spring plate 12 to push the connecting plate 8 upwards. The connecting plate 8 then causes the clamping plate 9 to move upwards, thus using the inner wall of the clamping plate 9 in conjunction with the connecting plate 14 to clamp and fix the wire. After the spring plate 12 pushes the connecting plate 8 upwards, turning the limiting plate 2 causes the threaded rod 4 to move in the threaded groove, causing the limiting plate 2 to move downwards, locking the position of the connecting plate 8 and further reinforcing the positioning of the spring plate 12. In this embodiment, both the connecting plate 8 and the connecting rod 6 are made of insulating plastic.

[0034] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
