DETAILED DESCRIPTION

[0030] The following will be described in detail below with reference to the accompanying Figure 1 - the accompanying Figure 5 , the present application will be further described in detail.

[0031] Embodiment 1:

[0032] A loosening-preventing wiring device, with reference to Figure 1 , comprising a housing 1 formed by stamping and folding, and the housing 1 is provided with a wire pressing screw 2, a conductive copper sheet 3, and a wire pressing spring sheet 4.

[0033] With reference to Figure 2 , the housing 1 is integrally formed with a clamping block 101 at one end before stamping and folding, and guide grooves 5 are formed on both sides of the clamping block 101, and the other end is integrally formed with two guide blocks 102 corresponding to the positions of the guide grooves 5, and a clamping groove 6 for abutting the clamping block 101 is formed between the two guide blocks 102. After the housing 1 is folded at least four times, the guide blocks 102 extend into the corresponding guide grooves 5, the clamping block 101 extends into the clamping groove 6 and abuts against the inner wall of the clamping groove 6, thereby being folded and enclosed to form a mounting cavity 7 with two openings.

[0034] With reference to Figure 2 , Figure 3 ​The housing 1 has a wire-pressing hole 8 on one of the sides adjacent to the mating surface of the snap-fit ​​block 101 and the snap-fit ​​groove 6. The wire-pressing screw 2 is threaded to the inner wall of the wire-pressing hole 8. In addition, the conductive copper sheet 3 passes through the two openings of the mounting cavity 7 in sequence, and after being assembled in place, the wire-pressing screw 2 abuts against the surface of the conductive copper sheet 3.

[0035] Two sets of limiting groups are integrally formed on the side wall of the conductive copper sheet 3. Each limiting group includes two limiting blocks 9 integrally connected to the opposite side walls of the conductive copper sheet 3. The two limiting blocks 9 located on the same side of the conductive copper sheet 3 cooperate to form a mounting groove, allowing the housing 1 to extend into the mounting groove. At the same time, the housing 1 abuts against the bottom of the mounting groove.

[0036] In addition, the conductive copper sheet 3 is integrally stamped between the two limiting groups to form a wire pressing protrusion 301, and the wire pressing protrusion 301 protrudes towards the side away from the wire pressing screw 2. The wire pressing protrusion 301 cooperates with the wire pressing spring 4 to clamp the wire or terminal.

[0037] Reference Figure 3 The inner wall surface of the mounting cavity 7, opposite to the wire pressing hole 8, is provided with several anti-slip textures and is designated as an anti-slip surface 10. In addition, a mounting plate 11 is integrally connected to one of the outer walls of the housing 1 on the anti-slip surface 10. The mounting plate 11 is punched and bent toward the side away from the wire pressing screw 2, and a fixing bubble is integrally connected to the side of the mounting plate 11 away from the housing 1.

[0038] Reference Figure 2 , Figure 3 The wire pressing spring 4 includes a fixing part 12, a limiting part 13, and a wire pressing part 14 formed by bending.

[0039] The fixing part 12 is flush with the side surface of the mounting plate 11 away from the housing 1, and the fixing bubble point penetrates the fixing part 12.

[0040] The limiting part 13 is flush with and abuts against the surface of the anti-slip surface 10, and the pressure spring 4 is integrally connected to the two opposite sides of the limiting part 13 with a snap-fit ​​plate 15. The side wall of the mounting cavity 7 near the snap-fit ​​plate 15 is provided with a limiting groove corresponding to the position of the snap-fit ​​plate 15. The snap-fit ​​plate 15 extends into and is installed in the adjacent limiting groove.

[0041] The pressure part 14 is inclined toward the conductive copper sheet 3.

[0042] The implementation principle of this application embodiment is as follows: During use, the wiring device is installed in the corresponding terminal slot within the corresponding electrical product, so that the side wall of the housing 1 abuts against the inner wall of the terminal slot. Furthermore, after the wiring device is installed in place, the conductive copper sheet 3 is fixed relative to the electrical product, and the housing 1 can move closer to or further away from the wire clamping screw 2. Simultaneously, the mounting plate 11 engages with the electrical product, thereby preventing the housing 1 from sliding in the direction of the wire or terminal insertion.

[0043] Between the external wire or the terminal pressing spring piece 4 and the conductive copper piece 3, after being installed in place, the pressing part 14 of the pressing spring piece 4 is deformed and presses the wire or the terminal, and at the same time applies pressure to the wire or the terminal, so that the wire or the terminal and the conductive copper piece 3 are mutually pressed, thereby preliminarily fixing the wire or the terminal in the wiring device.

[0044] Secondly, turn the pressing screw 2 with a tool so that the pressing screw 2 abuts against the conductive copper piece 3. When the pressing screw 2 is further rotated, the pressing screw 2 abuts against the conductive copper piece 3, and since the side wall of the housing 1 abuts against the inner wall of the terminal groove and the conductive copper piece 3 is relatively fixed with the electrical product, the anti-slip surface 10 of the housing 1 slides towards the pressing screw 2, and then the pressing spring piece 4 moves towards the conductive copper piece 3, thereby increasing the pressure of the pressing spring piece 4 and the conductive copper piece 3 on the wire or the terminal.

[0045] Embodiment 2:

[0046] A wiring device for preventing loosening, referring to Figure 4 、 Figure 5 The difference between it and Embodiment 1 is that the pressing spring piece 4 includes a clamping part for clamping the housing 1, a pressing part 14 for pressing the external wire or terminal, and a connecting part for connecting the clamping part and the pressing part 14.

[0047] Among them, the clamping part is composed of two "匚"-shaped fixing plates 16, and the two fixing plates 16 are respectively fixedly connected to both sides of the connecting part. The fixing plate 16 extends into the installation cavity 7 and abuts against the inner wall of the installation cavity 7. In addition, the housing 1 is provided with grooves for clamping the fixing plate 16 at both ends of the opening, so that the fixing plate 16 is clamped with the housing 1 after extending into the groove.

[0048] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
