When transmitting signals to various devices, signal wiring harnesses are needed. The appearance of signal wiring harness facilitates the connection of users to various devices. When the equipment is in use, it is necessary to ensure that the signal wiring harness has a good connection effect to ensure that there will be no poor contact.
At present, the existing signal wiring harness on the market cannot adjust the length of the wiring harness, and it occupies a large area. At the same time, the fixing effect of the existing signal wiring harness port is not good, and it is easy to cause the phenomenon of falling off. The existing signal wiring harness cannot be folded and stored, and the storage effect is not good.


Technical realization elements:
The purpose of the utility model is to provide a signal wire harness, which adopts a folding and winding design and adds a fixing device. It solves the problems that the existing device cannot adjust the length of the wire harness, the fixing effect at the port is not good, and the problem that it cannot be folded and stored.

In order to achieve the above objectives, the present utility model provides the following technical solutions:
A signal wire harness includes a box body, and a card slot plate is fixedly connected to the side end surface of the box body. The side end surface of the box body facing away from the slot plate is rotatably connected with a cover plate. The side end surface of the cover plate is rotatably connected with a fixing buckle matched with the slot plate. Three winding posts arranged horizontally and equidistantly are fixedly connected inside the box body. The winding column includes a rubber gasket, a connecting column and a connecting plate. The connecting plate is fixedly connected to the lower end surface of the connecting column. The rubber gasket is fixedly connected to the upper end of the connecting column, and a signal wire harness is wound around the side end surface of the connecting column. An end handle is fixedly connected to one end of the signal wire harness. The end of the end handle facing away from the signal wire harness is fixedly connected with a second end. The end of the signal wire harness away from the end handle is fixedly connected with the first end. The first end includes a splint, a fixing plate, a screw, a plug joint, a knob and a plug board. The splint is rotatably connected to the end surface of the plug-in board, and the plug connector is fixedly connected to one end of the plug-in board. There are two fixing plates, and the two fixing plates are symmetrically distributed on the side end surface of the plug-in plate. The screw is rotatably connected to the middle of the fixed plate, and the knob is fixedly connected to one end of the screw.


The winding post is fixedly connected to the bottom end of the inner side of the box body through a connecting plate.
The end of the plug-in board facing away from the plug-in connector is fixedly connected to one end of the signal wire harness.
The signal wire harness penetrates the side end surface of the box body and is fixedly connected with the end handle and the first end.
A moisture-proof pad is fixedly connected to the inner side of the cover plate.
The side end surface of the knob is provided with anti-skid patterns.
Compared with the prior art, the beneficial effects of the present invention are as follows:
1. The utility model winds the signal wire harness on the side end surface of the winding column by setting the winding column. The rubber gasket ensures that the signal wiring harness has a good fixing effect during winding and is not easy to loosen. The length of the signal wire harness can be adjusted by selecting the length of the winding post of the signal wire harness. The length of the signal wiring harness is convenient to place and does not occupy space, thereby avoiding a large footprint, and effectively solving the problem that the existing signal wiring harness cannot adjust the length of the wiring harness.
