Surge protectors are widely used in communication equipment, electronic medical equipment and military products to shield and protect wires and cables.

[0003] When an ordinary cable braiding machine is braiding a wave-breaking sleeve, the wires of each spindle on the braiding machine are finally passed through the braiding machine mold. At present, when braiding the wave-breaking sleeve, the tension of a single spindle is usually adjusted manually, and it is difficult to keep the tension of each spindle and single wire consistent, resulting in random swinging of the wave-breaking sleeve during braiding, which will cause uneven force on each spindle and single wire, and some single wires will be stretched and elongated. The stretched and elongated single wire will form single wire throwing when it is not under tension, which will affect the shielding effect of the wave-breaking sleeve. Utility Model Content

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] When the existing cable braiding machine is braiding the anti-wave sleeve, the parallel wires on each spindle of the braiding machine will eventually pass through the braiding mold on the braiding machine. At present, when braiding the anti-wave sleeve, the tension of a single spindle is usually adjusted manually. It is difficult to keep the tension of multiple single wires of each spindle consistent, resulting in random swinging of the anti-wave sleeve during braiding, which will cause uneven force on each spindle and single wire, and some single wires will be stretched and elongated. When the stretched and elongated single wire is not under tension, it will form single wire throwing, which will affect the shielding effect of the anti-wave sleeve.

[0024] like Figures 1 to 5 As shown, the utility model provides a cable wave-proof sleeve expansion and tension adjustment tool, including: an adjustment column 1 with a conical top and a clamping mechanism 2 for clamping and loosening the adjustment column 1, the adjustment column 1 is used in conjunction with a weaving mold on a weaving machine, and each weaving monofilament is in contact with the top outer wall of the adjustment column 1, which is used to adjust the tension of each weaving monofilament on the weaving machine and expand the sleeve at the same time.

[0025] The clamping mechanism 2 includes a connecting block 21, a connecting ring 22, three arc-shaped clamping plates 23 and a push rod 24. The connecting block 21 is a cylindrical structure. The connecting block 21 is used to connect to the center of the braiding disk of the braiding machine. The connecting ring 22 is arranged at the top outer edge of the connecting block 21. The three arc-shaped clamping plates 23 are radially slidably matched with the top of the connecting block 21, and the three arc-shaped clamping plates 23 are circumferentially spaced and distributed along the connecting block 21. In this embodiment, a slide groove 213 corresponding to the three arc-shaped clamping plates 23 is radially provided at the top of the connecting block 21, and a slider slidably matched with the slide groove 213 is provided at the bottom of the arc-shaped clamping plates 23, so as to realize the sliding match between the arc-shaped clamping plates 23 and the connecting block 21. The push rod 24 is threadedly connected to the connecting ring 22 and corresponds to the three arc-shaped clamping plates 23 one by one. At the same time, the end of the push rod 24 is rotationally matched with the arc-shaped clamping plates 23, and a clamping cavity 25 for clamping the bottom of the adjusting column 1 is formed between the three arc-shaped clamping plates 23. The adjusting column 1 includes a conical section 11 and a cylindrical section 12 connected in sequence from top to bottom, and the cylindrical section 12 is installed in the clamping cavity 25. The conical section 11 cooperates with the braiding mold of the braiding machine, and all the braided monofilaments pass through the gap between the conical section 11 and the braiding mold, and each braided monofilament fits the outer surface of the conical section 11 in the adjusting column 1. The outer surface of the conical section 11 is smooth and has a small friction coefficient, so the wear on each monofilament is small, and it is easy to slip off the adjusting column 1 and pass through the braiding mold on the braiding machine. The tension of each braided monofilament can be adjusted through the conical section 11, thereby solving the problem that each spindle and monofilament are unevenly stressed and easily form monofilament throwing. Under the action of external force, the push rod 24 is rotated, and the push rod 24 pushes the corresponding arc clamping plate 23 to slide radially along the connecting block 21, thereby realizing the clamping and loosening of the cylindrical section 12 of the adjusting column 1, and can clamp adjusting columns 1 of different sizes, so that wave-proof sleeves of different specifications can be woven.

[0026] The outer wall of the connecting block 21 is provided with a first thread segment 211 and a second thread segment 212 spaced apart from each other from top to bottom, and the pitch and thread direction of the first thread segment 211 are the same as the pitch and thread direction of the second thread segment 212. A base is provided at the center of the braiding disk of the braiding machine to cooperate with the connecting block 21, so that the connecting block 21 can be threadedly connected to the braiding disk of the braiding machine, which is convenient for the disassembly and installation of the tooling; the outer side of the first thread segment 211 is symmetrically milled with a plane, which is convenient for the staff to use a wrench to clamp the plane or manually hold the first thread segment 211 for installation and disassembly operations when using it.

[0027] like Figure 4As shown, the outer side of the arc clamping plate 23 is provided with a coaxial first through hole 231 and a second through hole 232 along the thickness direction of the arc clamping plate 23, wherein the side of the arc clamping plate 23 close to the adjusting column 1 is the inner side, and the other side away from the adjusting column 1 is the outer side; the first through hole 231 is close to the inner side wall of the arc clamping plate 23, and the second through hole 232 is connected to the outside, the diameter of the first through hole 231 is larger than the diameter of the second through hole 232, a baffle 233 is installed in the first through hole 231, and the end of the push rod 24 passes through the second through hole 232 and is connected to the baffle 233. The push rod 24 includes a handle portion 241, a threaded portion 242 and a light rod portion 243 which are axially connected in sequence, the threaded portion 242 is threadedly connected to the connecting ring 22, and the end of the light rod portion 243 passes through the second through hole 232 and is connected to the baffle 233. A threaded through hole is provided on the connecting ring 22, which is threadedly matched with the threaded portion 242 of the push rod 24. When the handle portion 241 is rotated, the threaded portion 242 can be driven to rotate in and out along the threaded through hole on the connecting ring 22, thereby pushing the arc clamping plate 23 to slide along the slide groove 213 on the connecting block 21, thereby changing the diameter of the clamping cavity 25 and realizing the clamping and loosening of adjustment columns 1 of different sizes.

[0028] When the wave-breaking sleeve expansion and tension adjustment tool of the utility model is in use, the base of the center position of the braiding disk of the connecting block 21 braiding machine is threadedly connected, and the cylindrical section 12 of the adjusting column 1 is placed in the clamping cavity 25 between the three arc-shaped clamping plates 23, and the push rod 24 is rotated under the action of external force. The push rod 24 will push the corresponding arc-shaped clamping plate 23 to slide radially along the connecting block 21, and then clamp and loosen the cylindrical section 12 of the adjusting column 1, so as to clamp the adjusting columns 1 of different sizes; the conical section 11 of the adjusting column 1 is tightly fitted with each braided monofilament on the braiding disk, and the parallel wires on each spindle are finally passed through the braiding mold. The conical section 11 of the adjusting column 1 expands the braided wave-breaking sleeve and makes each braided monofilament evenly stressed, thereby solving the problem that when the braiding machine is weaving the wave-breaking sleeve, each spindle and monofilament is easily subjected to uneven stress and monofilament throwing is easily formed, thereby affecting the shielding effect of the wave-breaking sleeve.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
