Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the invention.

As shown in fig. 1-3, the present embodiment provides a cable connecting and fixing device, which includes a body 1 made of an insulating material. The body 1 is provided with a plurality of through holes in a longitudinal direction, and a cable hole 11 into which a cable is inserted is formed. The body 1 is provided with a guide block 12 at a position close to the outside and in each cable hole 11, the guide block 12 is fixedly arranged along the length direction of the cable hole 11, and the guide block 12 gradually protrudes inwards from the outer end position of the cable hole 11 along the length direction. The middle position of the guide block 12 and the inner wall of the body 1 are provided with grooves which penetrate through the guide block 12 and open towards the cable hole 11, so that a pressing groove 13 is formed, and a pressing block 27 is arranged in the pressing groove 13. The pressing block 27 is connected with a spring 28 between the bottom walls of the pressing grooves 13. The body 1 at the position of the pressing block 27 is also provided with a pressing piece 2 which presses each pressing block 27 to the center direction of each cable hole 11. Preferably, the guide block 12 has a circular arc-shaped cross section. Preferably, the pressing block 27 is made of an elastic material.

Preferably, the pressing part 2 comprises a set of pressing rods 25 symmetrically arranged front and back, one end of each set of pressing rods 25 close to the pressing block 27 is connected with each other, the connection part extends to the pressing block 27 to form the pressing head 22, and the pressing head 22 is provided with a through groove 23 for the pressing head 22 to penetrate through and extend into the pressing groove 13 on the body 1. A rotating shaft 21 which can make the pressure rod 25 rotate up and down is arranged at the position inside the through groove 23 and on the pressure head 22. Preferably, one end of each group of pressing rods 25 away from the pressing block 27 extends towards the side wall of the body 1 at the opening position of the cable hole 11 on the side to form a limiting end 26, and a circular limiting rod 24 is fixed between each group of pressing rods 25 at the outer end position of the limiting end 26. A groove matched with the round limiting rod 24 is arranged on the side wall of the body 1 at the position of the round limiting rod 24 to form a clamping groove 15, and a clamping end 14 is formed on the side wall of one side of the clamping groove 15, which is close to the compression bar 25 on the side. Preferably, the pressing member 2 at each cable hole 11 includes two sets of pressing rods 25, and the two sets of pressing rods 25 are symmetrically arranged.

Preferably, one end of the pressing block 27 near the cable hole 11 extends in the width direction of the cable hole 11 to form a trapezoidal pressing end 29, and the outer end surface of the pressing end 29 is arc-shaped.

Based on foretell structure, the utility model discloses a fixing device is connected to cable follows the cable one end that needs to connect respectively according to the function the utility model discloses a cable hole 11 one end is passed, and the other end at cable hole 11 will connect the cable of being connected with another needs to twine and be connected, and each cable twines the back of accomplishing, will connect the joint that connects and slowly pull into cable hole 11, puts the department until the central point that comes to guide block 12. At this time, the pressing block 27 is in the pressing groove 13 due to the tensile force of the spring 28, and does not hinder the drawing-in of the joint. The cable joint is generally metal, and under the thickness change of guide block 12 in the in-process of drawing the joint in, the joint produces deformation gradually, and mutual more hugging closely is difficult for the pine to take off. After the connector comes to the center of the cable hole 11, the pressure rod 25 at one side of each cable hole 11 is pulled, and the round limiting rod 24 is pushed towards the clamping groove 15 until entering the clamping groove 15 and being limited by the clamping end 14. In the process of pushing the round limiting rod 24 to the clamping groove 15, the pressing rod 25 rotates by taking the rotating shaft 21 as a circle center, the pressing head 22 rotates downwards to abut against the pressing block 27, and the pressing block 27 overcomes the pulling force of the spring 28 to downwards extrude the cable connectors, so that the connection between the cable connectors is tighter.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
