Detailed implementation manners

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] As Figures 1-5 shown, the new type of general live wire connector includes a connector body 1. Two clamping grooves 2 are symmetrically formed inside the connector body 1. An opening groove 3 is formed outside the connector body 1 at the position of the clamping grooves 2. A clamping block 4 is slidably connected inside the clamping groove 2. A connection assembly 5 is installed at the bottom of the clamping block 4. A first screw 7 is connected to the bottom of the connection assembly 5. A first threaded hole 6 is formed at the center of the bottom of the connector body 1 at the extension of the lower part of the clamping block 4. The first screw 7 is threadedly connected to the first threaded hole 6 from the lower part of the connector body 1 and extends upward into the connection assembly 5. A screw head sleeve 8 is sleeved on the outer surface of the screw head of the first screw 7. A connection block 9 is fixedly connected to the outer surface of the screw head sleeve 8. A second screw 10 penetrates and is threadedly connected inside the connection block 9. A second threaded hole 11 is formed at the bottom of the connector body 1 in the extending direction of the second screw 10. The second screw 10 is threadedly connected to the second threaded hole 11 and extends into the connector body 1. By placing the wire inside the clamping groove 2 and rotating the first screw 7, the clamping block 4 slides upward in the clamping groove 2 until the wire is clamped and fixed. Then, the screw head sleeve 8 is sleeved on the screw head of the first screw 7, and the second screw 10 is screwed in until it extends into the clamping groove 2. At this time, when the first screw 7 becomes loose due to external reasons, it will be restricted by the screw head sleeve 8 and cannot rotate, and the screw head sleeve 8 is restricted by the second screw 10 and cannot rotate. However, a small loosening of the second screw 10 will not have any impact on the wire clamping. Only when its large loosening causes the entire screw head sleeve 8 to fall off will it start to affect the tightening degree of the first screw 7 and the wire clamping. Therefore, the second screw 10 replaces the first screw 7 to accept the loosening caused by external reasons, avoiding the direct impact of external reasons on the tightening degree after the wire is clamped, and greatly increasing the safety and stability after the wire connection. During actual use, the length of the screw head sleeve 8 can be set to be longer and sleeved on the threaded rod part of the first screw 7, thereby extending the distance required for the entire screw head sleeve 8 to fall off and making it more difficult for the first screw 7 to rotate.

[0022] As Figure 2As shown, in some embodiments, the screw head of screw 1 7 is hexagonal or octagonal, the inner surface of the screw head sleeve 8 fits the screw head surface of screw 1 7, and screw 2 10 is a hand-tightened screw. Specifically, by setting the screw head of screw 1 7 to be polygonal and fitting it to the inner surface of the screw head sleeve 8, the screw head will not rotate in the sleeve, and setting screw 2 10 to be a hand-tightened screw is more convenient during installation. In actual use, it can be set as a polygonal screw head to prevent the staff from subconsciously tightening it by hand.

[0023] like Figure 3 As shown, in some embodiments, the connecting component 5 includes a card slot 501, a card slot 501 is opened inwardly on the side of the clamping block 4, a plug plate 502 is horizontally inserted into the inside of the card slot 501, a ring 503 is fixedly connected to the center of the lower surface of the plug plate 502, the end of a screw 7 is sleeved inside the ring 503, a slide groove 504 is opened on the edge of the clamping block 4 away from the card slot 501, a slider 505 is fixedly connected to the edge of the clamping slot 2, and the slide groove 504 is slidably connected to the slider 505. Specifically, by inserting the plug plate 502 into the card slot 501 and tightening the screw 7, the screw 7 will squeeze the plug plate 502, and the plug plate 502 will squeeze the clamping block 4, thereby increasing the squeezed area of ​​the clamping block 4 and making it more evenly stressed. In the process of the clamping block 4 sliding vertically upward, the slider 505 begins to slide and connect the slide groove 504, so that the clamping block 4 cannot slide toward the openings on both sides of the clamping slot 2, thereby avoiding the position deviation of the clamping block 4.

[0024] like Figure 1 , 4 As shown in Figures 5 and 6, in some embodiments, the upper surfaces of the clamping groove 2 and the clamping block 4 are arrayed and fixedly connected with a plurality of anti-slip grooves 12. Specifically, the anti-slip grooves 12 increase the friction between the wire and the surface of the clamping groove 2 and the clamping block 4 after clamping, making the wire more firmly clamped.

[0025] like Figure 5 As shown, in some embodiments, an array of large anti-slip grooves 12 is fixedly connected to the opening edges on both sides of the clamping groove 2, and an array of small anti-slip grooves 12 is fixedly connected to the surface close to the inner side of the clamping groove 2. Specifically, by arranging anti-slip grooves 12 of different sizes, when the surface of the wire is squeezed and shaped for a long time and then pulled outward, it is blocked by the large anti-slip grooves 12, and the wire needs to be squeezed and deformed for a long time again before it can be easily pulled out, thereby further increasing the tightness of the wire after connection.

[0026] like Figure 1 As shown, in some embodiments, a tool connection hole 13 is opened in the middle of the top of the connector body 1. Specifically, the tool connection hole 13 is opened to facilitate the use of an insulating tool to move the device, making the operation safer.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
