Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and specifically to a wire-clamping terminal block. Background Technology

[0002] Terminal blocks are used to control and connect circuits. They are accessories used to realize electrical connections between electrical equipment and power sources. They are widely used and ubiquitous. There are often multiple terminal blocks in equipment. Therefore, during the processing and forming of equipment or circuits, operators often need to connect the terminals. The efficiency of the terminal block connection directly affects the processing and assembly efficiency of the equipment or the connection efficiency of the circuit.

[0003] Traditional terminal blocks typically use a rectangular frame and screws to tighten the wires at the input and output ends. This structure results in low wiring efficiency. Furthermore, some traditional terminal blocks use an integrated flexible connection structure for the parts that need to be opened or closed within the housing. However, the flexible connection has poor stability and is prone to breakage. Others use a split-type cover structure, but the cover is easily lost and disassembly is cumbersome. Therefore, traditional terminal blocks have many shortcomings, and their structure needs further improvement.

[0004] The prior art CN202220296195.9 describes a terminal block, which provides a novel terminal block structure design. By adopting a structure design in which the housing, cover, and flip cover interlock, the terminal block is made easier to connect, the structure is more robust and stable, and the operating efficiency is improved. However, during the use of the above-mentioned product, it was found that while the interlocking process damages the wire insulation, it can also easily cause a tear on the surface of the wire core. This tear is prone to cracking under external force during use, which can cause the cable to break at the connection point, resulting in poor wiring or continuity problems. Utility Model Content

[0005] In view of the prior art, the purpose of this utility model is to provide a wire clamping terminal block that can automatically clamp the wire.

[0006] The technical solution adopted by this utility model is as follows: a wire-clamping terminal block, including a terminal base and a terminal cover. The terminal cover includes a clip cover that is snapped and fixed to the terminal base and a wire-pressing cover that is hinged and flipped to engage with the terminal base. The wire-pressing cover and the terminal base are provided with wire-punching grooves at corresponding positions. The wire-punching grooves are provided with a wire-pressing plate for pressing and fixing the cable and a conductive copper part with wire-punching teeth.

[0007] As a further feature of the above solution, the wire pressing cover is provided with a hinge shaft that is hinged to the card cover, and the wire pressing cover is provided with a hook on the other side opposite to the hinge shaft. The terminal block is provided with a slot that matches the hook.

[0008] As a further feature of the above solution, the wire groove includes a through wire insertion port, and the wire pressing plate is fixed on the wire pressing cover and is located on the side where the cable enters relative to the wire insertion port.

[0009] As a further feature of the above solution, the terminal block and the cover are provided with matching side slots and side blocks, as well as insert plates and slots with inverted conical hooks.

[0010] As a further provision of the above scheme, the conductive copper component extends into the wire-locking groove formed by the card cover and the terminal block. The wire-locking groove is also provided with a V-shaped retaining spring and a wire-locking plate that is hinged to the card cover and abuts against the V-shaped retaining spring.

[0011] As a further feature of the above solution, the conductive copper component is provided with a wire-punching blade and a wire-placement groove 112, and the spacing between the wire-punching blades is smaller than the diameter of the wire-placement groove.

[0012] Beneficial effects: The terminal block of this utility model improves the structure of the wire clamping and bonding part by setting a wire pressing structure between the external cable and the bonding conductor. The wire pressing plate presses and folds the cable, causing the cable to bend back in a U-shape. This allows the cable to be guided to the wire pressing plate or terminal block under subsequent external pulling force, avoiding the pulling force from acting directly on the bonding point and preventing the cable from breaking or coming off, which would affect the use of the terminal block.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0021] like Figure 1-6 The diagram shows a wire-clamping terminal block, including a terminal base 1 and a terminal cover 2. The terminal cover 2 includes a clip cover 21 that is snapped and fixed to the terminal base 1 and a wire-pressing cover 22 that is hinged to the clip cover 21 and flipped to engage with the terminal base 1. The wire-pressing cover 22 and the terminal base 1 are provided with wire-punching grooves 31 at corresponding positions. The wire-punching groove 31 is provided with a wire-pressing plate 32 for pressing and fixing the cable and a conductive copper component 11 with wire-punching teeth 33. The conductive copper component 11 extends into the wire-clamping groove 41 formed by the clip cover 21 and the terminal base 1. The wire-clamping groove 41 is also provided with a V-shaped retaining spring 42 and a wire-clamping plate 43 that is hinged to the clip cover 21 and abuts against the V-shaped retaining spring 42.

[0022] As described above, in this embodiment, the terminal block uses a V-shaped retaining spring 42 to press the cable against one side. The elastic restoring force of the V-shaped retaining spring 42 presses the external cable against the conductive copper part 11 within the cable-holding groove 41 formed by the terminal block 1 and the retaining cover 21. Figure 4 , Figure 5 As shown, the conductive copper component 11 can be configured as a one-in-two-out configuration, and the V-shaped spring clip 42 can be configured as a single-row or double-row structure, improving the flexibility of cable use.

[0023] Compared to existing wire bonding structures, this embodiment simply pierces the outer insulation layer of the copper wire in the cable. Simultaneously, the conductive copper component 11 with bonding teeth 33 restricts and holds the cable in place. In this embodiment, the terminal block has a bonding groove 31 formed by the terminal block 1 and the wire clamping cover 22 that can press the cable firmly, thus preventing external pulling and dragging forces from directly acting on the cable in contact with the conductive copper component 11. Figure 3 The wire clamping cover 22 shown is provided with a wire clamping plate 32, which is located on the side opposite to the direction in which the cable extends from the side of the terminal block into the conductive copper part 11. In this way, when the front end is pierced by the wire-punching teeth 33 of the conductive copper part 11 and conducts electricity, the cable located at the wire clamping plate 32 is pressured by the wire clamping plate 32 and forms a U-shaped wire in the U-shaped groove of the terminal block 1. When the cable is pulled by external force, the pulling force is applied to the wire clamping plate 32 and the terminal block 1 through the U-shaped fold, and will not directly affect the electrical conduction section, thereby protecting it from the problem of breakage and loosening that affects contact conduction when pulled by external force.

[0024] As a further provision of the above solution, the wire pressing cover 22 is provided with a hinge shaft 23 that is hinged to the cover 21. The wire pressing cover 22 is provided with a hook 24 on the other side opposite to the hinge shaft 23. The terminal block 1 is provided with a slot 25 that matches the hook 24. The hook 24 and the slot 25 are used to lock the wire pressing cover 22 in place relative to the terminal block 1 after the wire pressing is completed.

[0025] As a further provision of the above solution, the wire-punching groove 31 includes a through wire insertion port 30, and the wire-pressing plate 32 is fixed on the wire-pressing cover 22 and is located on the side where the cable extends relative to the wire insertion port 30. As described above, the wire-pressing plate 32 is positioned to ensure that the front end of the cable contacts the conductive copper part 11, while the other side extending outward is pressed and tightened by the wire-pressing plate 32, so that its pulling force will not directly act on the wire-punching part.

[0026] As a further feature of the above solution, the terminal block 1 and the cover 21 are provided with matching side slots 51 and side blocks 52, as well as insert plates 54 and slots 55 with inverted conical hooks 53.

[0027] As a further feature of the above solution, the conductive copper component 11 is provided with a wire-punching blade 111 and a wire-holding groove 112. The spacing between the wire-punching blades 111 is smaller than the diameter of the wire-holding groove 112. The purpose of this structure is that when the cable is subjected to pressure from the upper pressure cap 22, it is pressed in through the V-shaped opening of the wire-punching teeth 33, and after the wire-punching blades 111 pierce the insulation, it enters the wire-holding groove 112. Here, the spacing between the wire-punching blades 111 is slightly smaller than that of the wire-holding groove 112. The wire-punching blades 111 are located on the wire-punching teeth 33 that extend upward from the body of the conductive copper component 11. The wire-punching teeth 33 in this part will undergo a certain deformation under external force, so as to achieve both the wire-punching effect and the locking effect. The size of the wire-holding groove 112 is basically the same as the diameter of the copper core but still slightly smaller, so as to maintain contact and locking, and improve the contact effect.

[0028] Furthermore, it is worth noting that this embodiment demonstrates a two-in-four-out terminal block configuration. Based on the above structural configuration, a three-in-or-more configuration can also be configured. Multiple parallel wire clamping structures can be arranged according to the number of incoming lines. The conductive copper component 11 is as follows... Figure 3 The wire extends from the lower part of the pressure section and then into the wire slot 41.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
