Description

Technical Field

[0001] The utility model relates to a wiring terminal. Background Art

[0002] In the prior art, the common wiring structure of the wiring terminal is similar to the structure in the Chinese utility model patent with the publication number CN216251377U, including a base, a screw, and a gasket sleeved on the screw. The base is divided into several compartments. The lower end of the screw is connected to a metal footrest. When wiring, the wire is inserted between the gasket and the metal footrest, and then the screw is tightened to press the wire against the metal footrest through the gasket. However, since the screw occupies the space in the middle of the gasket, the distance between the screw and the partition is only about one-fourth of the opening width of the compartment, resulting in a very small wire diameter range applicable to the wiring terminal. Content of the Utility Model

When wiring, the screw is rotated downward, and the screw presses down the wiring plate to press the wire tightly.

[0005] Extension parts are provided on both sides of the bottom plate, and notch openings are provided at the bottoms of the left and right sides of the corresponding wiring frame, and the extension parts are inserted into the notch openings.

[0006] First convex blocks with gradually increasing widths from top to bottom are provided on the front and rear inner walls of the installation groove, a stop block is provided between the lower end of the first convex block and the base, and second convex blocks with gradually decreasing widths from top to bottom are provided on the front and rear end faces of the left and right side walls of the wiring frame.

[0007] Pins are provided on the bottom surface of the wiring frame, and through holes for the pins to pass through are provided on the base.

[0008] The beneficial effect of the utility model: By arranging a spring piece in the wiring frame, the utility model can make full use of the opening size of the installation groove, greatly increasing the applicable wire diameter range under the same size condition. Description of the Drawings

[0014] As Figures 1-5 shown, a wiring terminal includes a base 1. An installation groove 2 is provided inside the base 1. The front side and the upper side of the installation groove 2 are open. A wiring frame 3 is provided inside the installation groove 2. A wire passing hole 31 is provided on the front side of the wiring frame 3. The upper surface of the wiring frame 3 is connected with a screw 4 by thread. An elastic piece 5 is provided inside the installation groove 2. The elastic piece 5 includes a bottom plate 51, a wiring plate 52, and a bending part 53 connecting the bottom plate 51 and the wiring plate 52. The bottom plate 51 is connected with the wiring frame 3. The wiring plate 52 is higher at the front and lower at the rear, and the wiring plate 52 is arranged below the screw 4. When wiring, the screw 4 is rotated downward, and the screw 4 presses down the wiring plate 52 to press the wiring plate 52 against the wire. The wiring schematic diagram is as Figure 4 shown.

[0015] Extension parts 54 are provided on both sides of the bottom plate 51. Notch openings 32 are provided at the bottom of the left and right sides of the corresponding wiring frame 3. The extension parts 54 are inserted into the notch openings 32. This structure is simple and can be disassembled and assembled quickly. Of course, other methods such as welding and connection with fasteners can also be adopted.

[0016] First convex blocks 21 with a gradually increasing width from top to bottom are provided on the front and rear inner walls of the installation groove 2. A stop block 22 is provided between the lower end of the first convex block 21 and the base 1. Second convex blocks 33 with a gradually decreasing width from top to bottom are provided on the front and rear end faces of the left and right side walls of the wiring frame 3. When the wiring frame 3 is placed in, the first convex block 21 is located above the second convex block 33, and the stop block 22 is located in front of and behind the wiring frame 3 to prevent the wiring frame 3 from falling out from the openings on the front side and the upper side of the installation groove 2.

[0017] Pin feet 34 are provided on the bottom surface of the wiring frame 3. The base 1 is provided with through holes for the pin feet 34 to pass through.

[0018] In addition to the beneficial effects described above, the utility model also has the following beneficial effects compared with the existing terminal blocks. For the terminal blocks with the existing structure, when wiring, the wire is inserted from the left or right side of the screw. After wiring, only one side of the gasket contacts the wire, and the wire is likely to fall off. To prevent the wire from falling off, generally a bend is made in the wire and it is put on the outside of the screw. However, the above operation requires the entire screw to be unscrewed, resulting in time-consuming wiring. In this application, the wire can be directly inserted and the screw can be tightened. Moreover, the wiring board 52 of the elastic piece 5 is in full contact with the wire, with a larger contact surface, which can firmly fix the wire. At the same time, the current-carrying capacity is stronger, avoiding problems such as resistance, heat, and voltage drop caused by poor connection.

[0019] The above shows and describes the basic principles, main features, and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, simple modifications and substitutions by ordinary technicians in the field are within the protection scope of the utility model.
