Description

Technical Field

[0001] The utility model belongs to the technical field of wiring terminals, in particular to a wiring terminal protection structure. Background Art

[0002] As the degree of industrial automation becomes higher and higher and the requirements for industrial control become more and more stringent and precise, the use of terminal blocks has gradually increased. With the development of the electronics industry, the scope of use of terminal blocks has become wider and wider, and the types have also increased. In addition to PCB board terminals, the most widely used ones are hardware terminals, nut terminals, spring terminals, etc.

[0003] When the wire is connected to the terminal, the insulation on the surface of the wire is stripped. If the wire diameter is too large, the conductive part of the wire will be exposed after the conductive core is inserted into the terminal. If the wire is stripped too long, the conductive part of the wire will also be exposed. Therefore, we have designed a terminal protection structure that can cover and protect the exposed wire part, improve the insulation performance, and avoid electric shock accidents caused by accidental touch. Utility Model Content

[0004] The purpose of the utility model is to provide a terminal protection structure, which has the advantages of covering and protecting the exposed wire positions, improving the insulation performance, and avoiding electric shock accidents caused by accidental touch, so as to solve the above-mentioned background technical problems.

[0010] 1. The beneficial effects of the present invention are as follows: the present invention covers the surface of the wire through the insulating cover, then inserts the rubber sleeve into the inner cavity of the wire outlet, and then rotates the flip plate to clamp the inner cavity of the card slot through the elastic clamping block. During this period, the abutment plate abuts against the bottom of the rubber sleeve, confining the wire to the inner cavity of the insulating cover for protection. The rubber sleeve is squeezed on the wire, increasing the firmness of the wire connection to the terminal body, thereby achieving the purpose of being able to cover and protect the exposed wire position, improving the insulation performance, and avoiding electric shock accidents caused by accidental touch.

[0011] 2. The utility model uses a wedge-shaped surface and a breaking block in combination. During the rotation of the flip plate, the wedge-shaped surface on the elastic card block contacts the insulating cover, causing the elastic card block to deform outward until the flip plate is completely attached to the bottom of the insulating cover. The restoring force of the elastic card block is stuck in the inner cavity of the card slot. The breaking block can facilitate the user to apply force to the elastic card block, causing the elastic card block to deform and detach from the inner cavity of the card slot.

[0012] 3. The utility model sets a limit groove, which slides in the inner cavity of the outlet. The limit groove can limit the rubber sleeve to prevent the rubber sleeve from escaping from the inner cavity of the outlet, thereby ensuring the stability of the rubber sleeve movement.

[0013] 4. The utility model increases the friction between the wire and the rubber sleeve by setting the anti-skid protrusions, restricts the movement of the wire, and improves the firmness of the wire after connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Hereinafter, embodiments of the terminal protection structure of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-3 The present invention shows a terminal protection structure according to an embodiment of the present invention, which includes a terminal head 2 on a terminal body 1: a plurality of wiring holes 3 are formed on the terminal head 2 at equal intervals, a plurality of insulating covers 4 adapted to the wiring holes 3 are rotatably connected to the top of the terminal head 2, a rectangular groove 7 is formed on the top of the wiring hole 3, a shaft 8 is fixedly connected to the inner cavity of the rectangular groove 7, the insulating cover 4 is rotatably connected to the surface of the shaft 8, a wire outlet 5 is formed at the right end of the insulating cover 4, and a limit assembly is provided between the bottom of the insulating cover 4 and the inner cavity of the wire outlet 5 6. The limit assembly 6 includes a flip plate 61 rotatably connected to the right side of the bottom of the insulating cover 4. The end of the flip plate 61 is fixedly connected to an elastic card block 62. The bottom of the left side of the insulating cover 4 is provided with a card slot 63 for the elastic card block 62 to engage. The inner cavity of the outlet 5 is provided with a rubber sleeve 66. One side of the flip plate 61 is fixedly connected to a plate 67 adapted to the rubber sleeve 66. The elastic card block 62 is provided with a wedge surface 64. One side of the elastic card block 62 is fixedly connected to a breaking block 65 extending to the outside of the inner cavity of the card slot 63. Through the wedge surface 64 and the breaking block 65 are used in conjunction with each other. During the rotation of the flip plate 61, the wedge-shaped surface 64 on the elastic card block 62 contacts the insulating cover 4, which will cause the elastic card block 62 to deform outward until the flip plate 61 is completely attached to the bottom of the insulating cover 4. The restoring force of the elastic card block 62 is stuck in the inner cavity of the card slot 63. The breaking block 65 can facilitate the user to apply force to the elastic card block 62, so that the elastic card block 62 is deformed and separated from the inner cavity of the card slot 63. Both sides of the rubber sleeve 66 are provided with limiting grooves 68. The rubber sleeve 66 It is slidably connected to the inner cavity of the wire outlet 5 through the limiting groove 68. Through the setting of the limiting groove 68, the limiting groove 68 slides in the inner cavity of the wire outlet 5. The limiting groove 68 can limit the rubber sleeve 66 to prevent the rubber sleeve 66 from escaping from the inner cavity of the wire outlet 5, thereby ensuring the stability of the movement of the rubber sleeve 66. Anti-slip protrusions 69 are provided on the inner side of the rubber sleeve 66. Through the setting of the anti-slip protrusions 69, the anti-slip protrusions 69 increase the friction between the wire and the rubber sleeve 66, limit the movement of the wire, and improve the firmness of the wire after connection.

[0022] Working principle: When the present invention is used, the wire is inserted into the wiring hole 3 and fixed by tightening the screws on the terminal body 1. Then the insulating cover 4 is flipped over so that the insulating cover 4 and the outlet 5 cover the surface of the wire. Then the rubber sleeve 66 is inserted from the bottom of the inner cavity of the outlet 5, so that the limiting groove 68 slides in the inner cavity of the outlet 5. Then the flip plate 61 is flipped over so that the elastic block 62 on the flip plate 61 is deformed and automatically stuck in the inner cavity of the card slot 63. The abutment plate 67 abuts against the bottom of the rubber sleeve 66, so that the rubber sleeve 66 moves upward and deforms against the surface of the wire, thereby strengthening the connection of the wire. This can achieve the purpose of covering and protecting the exposed wire position, improving the insulation performance, and avoiding electric shock accidents caused by accidental touch.

[0023] To sum up: the terminal protection structure covers the surface of the wire through the insulating cover 4, then inserts the rubber sleeve 66 into the inner cavity of the outlet 5, and then rotates the flip plate 61, and is clamped in the inner cavity of the card slot 63 through the elastic clamping block 62. During this period, the abutment plate 67 abuts against the bottom of the rubber sleeve 66, and the wire is confined to the inner cavity of the insulating cover 4 for protection. The rubber sleeve 66 is squeezed on the wire, which increases the firmness of the wire connection to the terminal body 1, thereby achieving the purpose of covering and protecting the exposed wire position, improving the insulation performance, and avoiding electric shock accidents caused by accidental touch.
