Description

Technical Field

[0001] This utility model relates to the field of switches, specifically to a quick-connect terminal block. Background Technology

[0002] Existing terminal blocks have long clamping distances, which can cause the wires to swing and back after wiring, resulting in loose connections and incomplete contact. In some products on the market that use screw-type wiring, the screws may not be tightened properly, leading to incomplete contact. Furthermore, if the installer is not skilled enough and the wires are not installed correctly, the switch may short-circuit, posing a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide a quick-connect terminal block that can quickly and securely connect wires.

[0004] The above objectives are achieved in this way.

[0005] A quick-connect terminal block includes a body and a handle. The body has a wiring cavity with a U-shaped spring inside. The handle is rotatably mounted on the body, with its actuating end extending out of the body for finger pressing and its pressing end located inside the body corresponding to the U-shaped spring. The U-shaped spring is formed by rolling an elastic material and has a wire-pressing end, an opening end, and a compression loop. The compression loop is located near the middle of the body. The opening end has an opening, and the end of the wire-pressing end is inserted into the opening, allowing it to move up and down within the opening. The opening is located close to the side wall of the body, with the portion below the wire-pressing end serving as a wire insertion port. The side wall of the body has a wire hole corresponding to the wire insertion port. When the actuating end is rotated under force, it drives the pressing end to press the compression loop. The compression loop causes the opening end to move downward, enlarging the wire insertion port so that the wire can be inserted through the wire hole. When the actuating end is released, the handle returns to its original position, the compression loop returns to its original position, and the opening end is pulled upward, with the opening end and the wire-pressing end together clamping the wire.

[0006] The objective of this utility model can also be optimized by the following technical measures.

[0007] Preferably, the spring clip is in the shape of a "P".

[0008] Preferably, the handle is provided with a pivot, and the handle rotates around the pivot.

[0009] Preferably, it also includes a conductive structure, which is a copper wire suspended in the lower part of the wiring cavity, with the upper part of the copper wire in contact with the U-shaped spring and the lower part of the copper wire in contact with the conductor.

[0010] By adopting the above technical solution, this utility model, through the setting of a P-shaped loop spring, allows the wire insertion port to be fully opened, reducing the problem of loose connection caused by incomplete opening of the wire insertion port. Furthermore, by placing the compression loop near the center of the main body and the wire insertion port close to the side wall of the main body, the wire can be inserted into the main body as much as possible, increasing the wire contact area. This simplifies electrical wiring and installation. Before installation, the electrician opens the handle, which can stand and be fixed. After inserting the wire, the handle is pushed back to its original position, completing the wiring without any additional operations. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Combination Figure 1 A quick-connect terminal block includes a main body 1 and a handle 2. The main body 1 has a wiring cavity 11, and a loop spring 3 is provided inside the wiring cavity 11. The handle 2 is rotatably mounted on the main body 1, and a rotating shaft 23 is provided on the handle 2. The handle 2 rotates around the rotating shaft 23. The actuating end 21 of the handle 2 extends out of the main body 1 for pressing with a finger, and the pressing end 22 of the handle 2 is located inside the main body 1 and corresponds to the compression loop 33.

[0017] Combination Figure 4 The loop spring 3 is formed by rolling up an elastic material. The loop spring 3 is "P" shaped and has a wire-pressing end 31, an opening end 32, and a compression loop 33. The wire-pressing end 31 extends horizontally and then connects to the compression loop 33, which is composed of a semicircle and an arc. After the arc transition, the compression loop 33 extends vertically downward to the opening end 32. An opening 34 is formed on the opening end 32. The end of the wire-pressing end 31 is inserted into the opening 34 and can move up and down within the opening 34. The opening 34 is set close to the side wall of the main body 1. The part of the opening 34 below the wire-pressing end 31 is the wire insertion port 33. A wire hole 10 is also provided on the side wall of the main body 1 at the position corresponding to the wire insertion port 33. The wire hole 10 corresponds to the wire insertion port 30. When the loop spring 3 is in an undeformed state, the wire insertion port 30 is not open, and the loop spring 3 closes the wire hole 10.

[0018] Combination Figure 2 When the actuating end 21 is rotated under force, it drives the pressing end 22 to press and compress the return ring 33. The opening end 32 moves downward away from the wire pressing end 31. The wire insertion port 30 becomes larger and at the same time, the wire hole 10 is released so that the wire can be inserted from the wire hole 10 to the wire insertion port 30.

[0019] Combination Figure 3 When the wire is inserted, release the toggle end 21, the handle 2 returns to its original position, and the compression loop 33 returns to its original position. At the same time, the opening end 32 is pulled upward by the elastic force, so that the opening end 32 moves upward and closes to the wire pressing end 31. At this time, the opening end 32 of the loop spring 3 clamps the wire with the wire pressing end 31.

[0020] It also includes a conductive structure 4, which is a copper wire suspended in the lower part of the wiring cavity 11. The wire clamping end 31 is set on the conductive structure 4. When the wire is inserted into the wire insertion port 30, the wire is clamped by the U-shaped spring 3. At this time, the lower part of the conductive structure 4 is in contact with the wire.

[0021] The compression loop 3 is positioned close to the center of the main body 1, and the wire insertion port 30 is positioned close to the side wall of the main body 1. This arrangement allows the wire to extend into the main body 1 as much as possible, ensuring that the wire makes full contact with the conductive structure 4.

[0022] Specific implementation methods

[0023] When the lever 2 is turned, the push end 21 is pressed and the compression loop 33 is compressed. As the two ends of the loop spring 3 move away from each other, the wire insertion port 30 becomes larger. At this time, the wire is inserted. When the lever end 21 is released, the loop spring 3 is reset by the elastic force, and the two ends move closer to each other to clamp the wire. The loop spring 3 is set on the upper part of the conductive structure 4. The wire is pressed on the conductive structure 4 by the loop spring, forming an electrical circuit.
