DETAILED DESCRIPTION

[0016] The present invention will be described clearly and completely below with reference to the accompanying drawings and embodiments: like Figures 1 to 5As shown, a meter wiring device described in the present invention comprises an insulating shell 1, both ends of the insulating shell 1 are provided with a through hole 2 which is in communication with the inside thereof, for the wire to be passed through the inside of the insulating shell 1; a cover plate 3 is adjustable at the top of the insulating shell 1, and both ends of the bottom of the cover plate 3 are provided with a positioning sleeve 4, the positioning sleeve 4 is located in the insulating shell 1, and a limiting groove 5 is provided on the positioning sleeve 4 for limiting and fixing the wire; a positioning plate 6 is elastically provided on the side wall of the positioning sleeve 4, and the positioning plate 6 is made of insulating plastic material, which can not only insulate to ensure safety, but also can use its own flexibility to achieve elastic connection with the positioning sleeve 4, so as to achieve positioning or release with the insulating shell 1; a positioning protrusion 7 is provided at the end of the positioning plate 6, and a positioning groove for the positioning protrusion 7 to extend into the insulating shell 1 for positioning is provided, and the positioning operation of the positioning sleeve 4 can be achieved by placing the positioning protrusion 7 in the positioning groove, thereby achieving the pressing and positioning of the wire, and ensuring the stability of the wire; a conductive sheet 8 is provided in the insulating shell 1 between the two positioning sleeves 4, which is used to achieve conduction of the wires on both sides after power is supplied. When using this embodiment, first release the positioning connection between the positioning protrusion 7 and the positioning groove, then pull up the cover plate 3 to drive the positioning sleeve 4 to rise, and finally insert the end of the wire through the through hole 2 so that its end abuts against the conductive sheet 8, and finally press down the cover plate 3 to achieve the positioning and pressing of the wire by the positioning sleeve 4. Since the positioning sleeve 4 is limited by the connection between the positioning protrusion 7 and the positioning groove, the stability of the wire after installation can be guaranteed, and the safety during use can be improved. The whole operation is simple and quick, and there is no need to wind the wire, which avoids damage to the wire.

[0017] Furthermore, the cover plate 3 is elastically connected to the insulating housing 1, so that after the positioning protrusion 7 is disengaged from the positioning groove and the positioning of the positioning sleeve 4 is released, the cover plate 3 drives the positioning sleeve 4 to rise under the elastic restoring force, which is convenient for the installation and extraction of the wire. Specifically, a connecting rod 9 is provided at the bottom of the cover plate 3, and the connecting rod 9 is connected to the positioning sleeve 4. A guide hole 10 for the connecting rod 9 to be movably inserted is provided on the insulating housing 1. A spring connected to the connecting rod 9 is provided in the guide hole 10. When the positioning protrusion 7 is located in the positioning groove, the spring is in a compressed state, so as to release the connection between the positioning protrusion 7 and the positioning groove, so that the cover plate 3 automatically pops up under the elastic restoring force. Preferably, a groove 11 is provided at the top of the insulating housing 1, and a sealing rubber block 12 matching the groove 11 is protruded from the bottom of the cover plate 3. By providing the sealing rubber block 12, the tightness of the connection between the cover plate 3 and the insulating housing 1 can be improved to ensure safety.

[0018] Furthermore, in this embodiment, a cylindrical cable sleeve 13 is provided in each penetration hole 2. The cable sleeve 13 is made of a flexible rubber material and can be used to constrain the wires. Preferably, a flexible protrusion 14 is provided on the inner wall of the cable sleeve 13. The flexible protrusion 14 can increase the friction with the wires, increase the resistance of the wires to pass in and out, and further improve the stability of the wires after installation.

[0019] Furthermore, two auxiliary limit rods 16 are elastically hinged on the inner wall of the insulating shell 1 through a hinge shaft 15 and a torsion spring. Each auxiliary limit rod 16 has an H-shaped structure and is arranged obliquely in the insulating shell 1. A lower positioning sleeve 17 is provided at one end thereof close to the conductive sheet 8. An upper positioning sleeve 18 is elastically provided in the insulating shell 1. Arc grooves matching the wire are provided on the opposite end faces of the lower positioning sleeve 17 and the upper positioning sleeve 18. The size of the two arc grooves after docking is smaller than the diameter of the wire, so that the lower positioning sleeve 17 and the upper positioning sleeve 18 can dock with each other to complete the tight clamping of the wire; the end of the auxiliary limit rod 16 away from the conductive sheet 8 is located below the positioning sleeve 4. After the wire is installed, the lower pressure cover plate 3 will apply downward pressure to the auxiliary limit rod 16 as the positioning sleeve 4 moves downward. At this time, the end of the auxiliary limit rod 16 provided with the lower positioning sleeve 17 is tilted along the hinge point and abuts against the upper positioning sleeve 18, thereby achieving re-clamping of the wire and ensuring the stability of the wire. The elastic setting of the upper positioning sleeve 18 can provide a certain buffer during the wire clamping process, and use the elastic restoring force of the positioning sleeve to achieve tight clamping of the wire. Specifically, the insulating housing 1 is provided with a buffer cavity 19 extending downward on both sides close to the conductive sheet 8, and a buffer rod 20 is provided in the buffer cavity 19 through a spring, and the upper positioning sleeve 18 is provided on the buffer rod 20; when the wire is clamped, the spring is in a compressed state.

[0020] In addition, a support platform 21 is arranged in the insulating sleeve below the positioning sleeve 4, and the support sleeve cooperates with the positioning sleeve 4 to achieve a tight clamping of the wire. A receiving groove 22 is provided on both sides of the support platform 21 for the two side walls of the positioning sleeve 4 to extend into; and an adjustment groove 23 is provided on the adjacent side walls of the receiving groove 22 from top to bottom for the positioning plate 6 and the auxiliary limiting rod 16 to be movably penetrated, so as to adjust the normal movement of the positioning plate 6 and the auxiliary limiting rod 16. When the side walls on both sides of the positioning sleeve 4 enter the receiving groove 22, the spacing between the limiting groove 5 on the positioning sleeve 4 and the support platform 21 is gradually reduced until the wire is tightly clamped. Preferably, a placement groove 24 is provided on the support platform 21, and the placement groove 24 is used to accommodate the wire and limit the wire on the support platform 21. The depth of the placement groove 24 is small, which is smaller than the radius of the wire. As long as the limiting accommodation of the bottom of the wire can be achieved, it is sufficient to avoid setting it too large to affect the tight clamping of the positioning sleeve 4 and the support platform 21 on the wire.

[0021] In this embodiment, a flexible arc-shaped sealing gasket 25 is provided at a position on the insulating housing 1 opposite to the positioning groove. The sealing gasket 25 is made of an insulating material and is an outwardly convex arc-shaped structure, providing a space for accommodating the positioning protrusion 7. The provision of the sealing gasket 25 can achieve the sealing of the positioning groove to ensure safety, and at the same time can facilitate the pressing and removal of the positioning protrusion 7 from the positioning groove. In addition, in this embodiment, a flame-retardant cushion layer is also provided inside the insulating housing 1 to further enhance safety performance.

[0022] When the present invention is in use, the sealing gasket 25 is first pressed to release the positioning connection between the positioning protrusion 7 and the positioning groove, and then the cover plate 3 will automatically pop up under the restoring force of the spring and drive the positioning sleeve 4 to rise, and finally the end of the wire is inserted through the through hole 2 so that its end is in contact with the conductive sheet 8, and finally the cover plate 3 is pressed down to clamp the wire between the positioning sleeve 4 and the support platform 21. At this time, as the positioning sleeve 4 gradually moves downward, the auxiliary limit rod 16 will be pressed down to rotate along the hinge point, and the end with the lower positioning sleeve 17 will rise. As the positioning protrusion 7 on the positioning plate 6 enters the positioning groove for positioning, the lower positioning sleeve 17 will dock with the upper positioning sleeve 18 to complete the tight clamping of the wire and realize the re-fixation of the wire, which greatly ensures the stability of the wire. The entire operation is simple and quick, and there is no need to wind the wire, which avoids damage to the wire. The structure is simple and practical.
