Description

Technical Field

[0001] This invention relates to the field of terminal block technology, and in particular to a pull-back rod double-deformation spring-type terminal block. Background Technology

[0002] Spring-loaded terminal blocks work by inserting a wire or crimped terminal into the inlet hole. The spring deforms and springs back, pressing the wire against a conductive plate, thus creating conductivity. Common spring-loaded terminal block buttons are push-button or rotary. The advantage of this structure is its simplicity; however, the disadvantages include the need for larger tools or operating space, the difficulty in manufacturing the spring, and a shorter lifespan.

[0024] like Figures 1 to 4 As shown, this embodiment of a pull-back rod double-deformation spring-type terminal block includes an insulating shell 1, a pull-back rod 2, a spring 3, and a conductive plate 4. The pull-back rod 2 is inserted from one side of the insulating shell 1 and is rotatably connected to the insulating shell 1. The spring 3 is disposed inside the insulating shell 1 and has at least two bends. One end of the spring 3 is fixed, and the other end is a free end 31, which is connected to the pull-back rod 2. The conductive plate 4 includes a side plate 41, which is located inside the insulating shell 1 and is positioned opposite to the free end 31 of the spring 3. In the above technical solution, the multiple bends of the spring 3 provide crimping force and reduce the yield stress during the deformation of the spring 3. The wire can be directly inserted into the insulating shell 1. When inserting the wire, first pull the pull-back rod 2, which drives the spring 3 to rotate, allowing the wire to be inserted. Release the pull-back rod 2, and the spring 3 will spring back, pressing the wire conductor to connect with the conductive plate 4, thereby achieving conductivity. When the conductor detaches, pulling the return rod separates the spring 3 from the conductor, pulling the conductor out. Releasing the return rod returns the spring to its original position. The operation of the return rod 2 is ergonomic, and the spring with multiple deformations provides better crimping force, ensuring reliable electrical connection of the terminal block. It is widely used in the rail transit and transportation industries.

[0025] In this embodiment, the spring piece 3 includes a first bending portion 32 and a second bending portion 33. The insulating outer shell 1 contains a first column 11 and a second column 12. The first bending portion 32 is located at the position of the first column 11, and the second bending portion 33 is located at the position of the second column 12. Using this technology, the spring piece can be positioned by the first and second columns. The second column 12 has a slot, and the pull-back rod 2 has a first protrusion 21, which corresponds to the slot, allowing the pull-back rod to rotate. The first protrusion 21 is located in the pull-back rod, forming a lever. The pull-back rod 2 has a second protrusion 22, which corresponds to the connecting hole 34 of the spring piece 3, allowing the pull-back rod 2 to drive the spring piece 3. The first protrusion 21 and the second protrusion 22 are respectively located on the front and back of the pull-back rod 2. The side of the spring piece 3 has a connecting piece 35, and the connecting hole 34 is located on the connecting piece 35. The exposed portion of the pull-back rod 2 has an extended mounting platform 23 for convenient operation. The conductive plate 4 has an embossed pattern 42 to increase the friction between it and the inserted conductor. The insulating shell 1 has a wire inlet hole 13, and the spring piece 3 and the conductive plate 4 are located on both sides of the wire inlet hole 13. The free end 31 of the spring piece 3 is inclined relative to the conductive plate 4.

[0026] This embodiment of a pull-back rod double-deformation spring-type terminal block has a spring with a double-deformation structure, which occupies little space, is easy to operate, can provide better crimping force, and ensures the reliable electrical connection of the terminal block. It is widely used in the rail transit and transportation industries.

However, the present invention is not limited to the specific embodiments described above. Various modifications or alterations can be made without departing from the scope of the claims.
