DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 4The utility model provides a technical solution: a conical automatic quick wire clamp, comprising a shell 1, a fixed cavity 17 arranged inside the shell 1, and jacks 16 arranged at both ends of the shell 1, the jacks 16 are convenient for inserting the wire into the shell 1, and the jacks 16 are connected with the fixed cavity 17, a plurality of clamping members 11 are arranged inside the fixed cavity 17, the clamping members 11 are used to clamp the wire, the inner wall of the shell 1 is provided with a limit strip 6, the outer side of the clamping member 11 is penetrated with a limit groove 5 matched with the limit strip 6, the limit strip 6 and the limit groove 5 are used to limit the clamping member 11 to prevent the clamping member 11 from rotating with the shell 1, thereby improving the clamping member 11 The clamping effect ensures that the wire is firmly fixed. At the same time, under the restriction of the limiting groove 5 and the limiting strip 6, the clamping piece 11 and the housing 1 can still slide to ensure its normal use. A positioning hole 13 and a positioning column 14 are provided on one side of the adjacent clamping piece 11. The positioning hole 13 and the positioning column 14 are used to limit the two clamping pieces 11 to prevent misalignment between the two clamping pieces 11 and affect the fixing effect. A contraction portion 15 is provided at one end of the positioning column 14. The inner side wall of the clamping piece 11 is provided with teeth 10. The teeth 10 can increase the friction between the clamping piece 11 and the wire, thereby improving the connection strength between the clamping piece 11 and the wire.

[0019] Among them, a fixing part 9 is fixed in the middle of the fixing cavity 17. When the wire pushes the guide head 4 to reach the fixing part 9, the fixing part 9 fixes the guide head 4. A through hole 8 is penetrated on the fixing part 9. The through hole 8 facilitates one end of the two guide heads 4 to contact each other, thereby realizing the conduction of the two wires.

[0020] A spring 7 is provided between the fixing member 9 and the clamping member 11, and the spring 7 is used to push the clamping member 11 so that the clamping member 11 automatically returns to its original position to clamp the wire.

[0021] Among them, plugs 2 are fixedly installed at the two jacks 16. The plugs 2 are used to seal between the shell 1 and the wire to prevent external impurities from entering the shell 1 and affecting the conductive performance. A through hole 3 is provided on the plug 2 to facilitate the wire to pass through the plug 2.

[0022] A guide head 4 is provided between the plug 2 and the clamp 11 . The guide head 4 is made of conductive metal. The guide head 4 makes it easier for the wire to pass through the clamp 11 and the spring 7 . One end of the guide head 4 is a hemispherical structure.

[0023] One end of the clamping member 11 close to the plug 2 is provided with a chamfer 12 , and the chamfer 12 is used to guide the guide head 4 so that the guide head 4 can enter between the two clamping members 11 more easily.

[0024] Specifically, when fixing, the wire is inserted into the shell 1 from the through hole 3, and one end of the wire is inserted into the guide head 4. The wire pushes the clamping piece 11 to move toward the middle position of the shell 1, and the clamping piece 11 compresses the spring 7. When the clamping piece 11 moves to a position with a larger space, the two clamping pieces 11 will open, and the wire will push the guide head 4 through the clamping piece 11 and the spring 7 until it contacts the fixing piece 9. The two guide heads 4 contact each other at the through hole 8 to achieve conduction between the two wires. The clamping piece 11 will reset under the action of the spring 7, and the clamping piece 11 clamps the wire. Moreover, under the pulling force of the wire, the connection between the wire and the clamping piece 11 is more firmly established, thereby achieving fixation of the wire.
