Abstract
Description
Technical Field
[0001] This utility model applies to the field of electrical components technology and provides a riveted terminal block. Background Technology
[0002] Terminal blocks are electrical components used to make electrical connections. They are commonly used to connect wires or conductive sheets in circuits. In practical use, after wiring is completed, the terminal blocks are usually fixed in place to ensure a secure connection. Common methods include fixing the terminal blocks with solder or screws. However, soldering carries the risk of detachment after prolonged use and is inconvenient to disassemble. When using screws, a hole is usually drilled in the bottom of the terminal block, and the screw is passed through the hole to fix the terminal block to the circuit board or other location. However, since terminal blocks are generally made of thin metal plates, they are prone to slippage and loosening over time if the screw is directly used to fix them. Utility Model Content
[0003] Therefore, this utility model provides a riveted terminal block. By riveting a locking pad onto the fixed base plate of the terminal body, the fixing part of the terminal block is thickened. Then, a terminal locking thread hole is drilled on the combination of the fixed base plate and the locking pad. The terminal locking thread hole extends through the fixed base plate and the locking pad. In this way, the riveted terminal block can be firmly fixed by passing bolts or screws through the locking pad and the fixed base plate.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a riveting type terminal block, comprising:
[0005] The terminal body is a U-shaped conductive metal strip that has been cut and bent. The terminal body includes a fixed base plate and two wiring side plates fixedly disposed on the left and right sides of the fixed base plate. At least two wiring terminals are provided on the end of the wiring side plate away from the fixed base plate. A first threaded hole is provided in the middle of the fixed base plate.
[0006] A locking pad is provided, the lower end face of which is riveted to the upper end face of the fixed base plate. A second threaded hole that matches the first threaded hole is provided in the middle of the locking pad. The internal threads of the first threaded hole and the second threaded hole are connected end to end, so that the first threaded hole and the second threaded hole form a continuous terminal locking threaded hole.
[0007] Furthermore, a pad limiting hole is provided at the position where the wiring side plate connects to the fixed base plate, and pad limiting blocks that are adapted to the pad limiting hole are fixedly provided on the left and right sides of the locking pad respectively.
[0008] Furthermore, pad block limiting flanges are fixedly provided on the front and rear sides of the fixed base plate, and the pad block limiting flanges abut against the locking pad blocks.
[0009] Furthermore, the limiting flange of the pad block is an arc-shaped plate bent towards the locking pad block side, and the outer wall of the limiting flange of the pad block abuts against the side wall of the locking pad block.
[0010] Furthermore, the end of the wiring terminal away from the wiring side plate is arc-shaped.
[0011] Furthermore, the thickness of the fixed base plate, the wiring side plate, and the limiting flange of the pad block are the same.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In the present invention, a locking pad is riveted onto the fixing base plate of the terminal body to thicken the fixing part of the terminal. Then, a continuous terminal locking thread hole is drilled at the joint between the fixing base plate and the locking pad. In this way, when fixing the terminal, because the thickness of its fixing part is sufficient, it can withstand higher bonding force and its installation will be more secure.
[0014] 2. The locking pads on the left and right sides are engaged with the pad limit holes on the wiring side plate. At the same time, pad limit flanges that abut against the locking pads are provided on the front and rear sides of the fixed base plate, which improves the firmness of the connection between the locking pads and the terminal body and further prevents the locking pads from separating from the terminal body.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example 1, refer to Appendix Figure 1 Appendix Figure 2 The present invention provides a riveting type terminal block, including a terminal body 100 and a locking pad 200, as shown in the attached figure. Figure 3 As shown, the terminal body 100 is a U-shaped structure formed by cutting and bending a conductive metal strip. The terminal body 100 includes a fixed base plate 110 and two wiring side plates 120 fixedly disposed on the left and right sides of the fixed base plate 110. At least two wiring terminals 121 are provided at the end of the wiring side plate 120 away from the fixed base plate 110. The wiring terminals 121 serve as the main connectors for electrical connection. The ends of the wiring terminals 121 away from the wiring side plate 120 are rounded, which reduces the risk of injury to the user. The lower end face of the locking pad 200 is riveted to the upper end face of the fixed base plate 110. A first threaded hole 111 is provided in the middle of the fixed base plate 110. A second threaded hole 220, matching the first threaded hole 111, is provided at the middle position of the tight pad 200. The internal threads of the first threaded hole 111 and the second threaded hole 220 are connected end to end, thus forming a continuous terminal locking threaded hole. In conventional designs, a through hole larger than the bolt size is usually used, and fixation is achieved solely through the tightening force of the bolt and nut. However, a continuous terminal locking threaded hole means that the same bolt or screw can be installed through a threaded connection. Compared with conventional designs, this method provides a more secure connection. A pad limiting hole 122 is provided at the connection position between the wiring side plate 120 and the fixed base plate 110. Additionally, as shown in the attached... Figure 4 As shown, the left and right sides of the locking pad 200 are respectively fixed with pad limiting blocks 210 that are adapted to the pad limiting hole 122. The pad limiting blocks 210 can be inserted into the pad limiting hole 122 to further limit the locking pad 200 and prevent the riveting part from loosening and falling off.
[0026] In the actual manufacturing of the riveted terminal block in this embodiment, the base plate 110 and the wiring side plate 120 have the same thickness. This allows the terminal body 100 to be directly machined from a single conductive metal strip. In actual production, the shapes of the wiring ends 121 on the two wiring side plates 120 and the pad limiting holes 122 are first punched into the conductive metal strip. Then, the locking pads 200 are riveted onto the base plate 110. At this point, the two wiring side plates 120 on both sides of the base plate 110 are folded upwards using equipment. The fixed base plate 110 and the two terminal side plates 120 form a "U" shape. During this process, the pad limit block 210 on the locking pad 200 will just be inserted into the pre-cut pad limit hole 122. Then, a drilling device is used to drill a hole in the joint between the locking pad 200 and the fixed base plate 110. The drill bit passes through the locking pad 200 and the fixed base plate 110 in sequence, so as to obtain the above-mentioned continuous terminal locking thread hole, and finally obtain the final product of the riveted terminal mentioned above.
[0027] Example 2, refer to Appendix Figure 5 Appendix Figure 6 As shown, based on Embodiment 1, pad limiting flanges 112 are fixedly provided on the front and rear sides of the fixed base plate 110. The pad limiting flanges 112 are arc-shaped plates bent towards the locking pad 200. The outer wall of the pad limiting flanges 112 abuts against the side wall of the locking pad 200. The thickness of the pad limiting flanges 112 is the same as that of the fixed base plate 110 and the wiring side plate 120. The pad limiting flanges 112 reinforce and limit the locking pad 200 by abutting against it. With the pad limiting hole 122, the locking pad can be locked simultaneously in four directions: front, back, left, and right. Block 200 is more securely positioned. In actual production, compared with the scheme of Embodiment 1, in Embodiment 2, when punching the terminal 121 and the pad block positioning hole 122, the shape of the pad block positioning flange 112 before bending is punched out. When the pad block positioning clip 210 on the locking pad block 200 is inserted into the pad block positioning hole 122, the pad block positioning flange 112 is bent into an arc plate shape towards the locking pad block 200 by a special edge rolling device, and finally abuts against the side wall of the locking pad block 200, forming the final product of the riveted terminal mentioned in Embodiment 2.
