Description

Technical Field

[0001] The utility model relates to the technical field of data cables, in particular to a pulling-resistant computer data cable. Background Art

[0002] Computer cables are cables that connect various external devices to the computer host. They are divided into power cables and data cables. The power cable is mainly used to provide power to the device and charge the battery. The data cable is mainly connected to the external input, output or storage device through the computer serial port, parallel port and USB interface to achieve the purpose of mutual information transmission. However, after the computer is used for a long time, the internal cables of the computer will become tangled together, which is very troublesome when you need to find and replace the cables.

[0003] When existing computer USB cables are connected and used, they are usually connected in a plug-in manner, but they do not have a certain anti-pull function after connection, so that the cable is easily pulled by the outside or accidentally touched by the foot during use. When it is suddenly pulled sharply and changes position, since the length of the data cable is a fixed value, the end of the data cable and the end of the connected device will be pulled and separated, which can easily cause the contact part between the two ends to deform, resulting in poor contact and information distortion during connection. In severe cases, the data cable may be torn off, causing damage to components and equipment. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is that the existing computer USB connection cable is usually connected in a plug-in manner when being connected and used, but it does not have a certain anti-pull function after being connected, so that the connection cable is prone to sudden and large-scale pulling and position change due to accidental external pulling or accidental touch of the foot during use. Since the length of the data cable is a fixed value, the end of the data cable and the end of the connection device will be pulled and separated, which can easily cause the contact part between the two ends to deform, resulting in poor contact and information distortion during connection. In severe cases, the data cable may be torn off, causing damage to component equipment.
