Description

Method of forming a secure connection structure

The present invention relates to a method of forming a secure connection structure, and more particularly to a method of forming a secure connection structure when a network cable is inserted.

In terms of appearance, the network cable includes a wire body and connecting parts at both ends of the wire body. The connection part is provided with a shrapnel. When the connection part is inserted into the network jack, the shrapnel can be snapped into the recess in the network socket, and the end of the shrapnel will protrude from the network socket. When the user wants to remove it When using a network cable, you can press the shrapnel to release the snap between the shrapnel and the network jack.

However, some users do not want the network cable to be plugged and unplugged at will, so network cables with a locking structure are beginning to be used. This type of network cable is mainly used to lock the snap between the spring and the network jack. If there is no unlocking component, the network cable cannot be easily removed. For example, in the US Patent No. 7,163,414 shown in FIG. 1 (hereinafter referred to as the 414 patent), the network cable 500 includes a connecting portion 510 and a socket portion 520 sleeved on the connecting portion 510, and a pair of elastic pieces 511 are provided on the connecting portion 510. The sleeve 520 can slide on the connecting portion 510 to compress or release the two elastic pieces 511. When the sleeve 520 is at the position where the two elastic pieces 511 are compressed, the user can insert the connecting portion 510 into the network jack, and then put the sleeve The barrel 520 slides to the position where the two elastic pieces 511 are released, so that the two elastic pieces 511 can be engaged with the network jack, and the sleeve 520 can be locked in this position. A special unlocking tool is required to move the sleeve 520 again. Time network cable 500 cannot leave the network jack simply by pulling.

However, the 414 patent combines the locking mechanism with the network cable 500. When making the network cable 500, the manufacturer must not be able to take into account all lengths and colors of the network cable, and therefore cannot meet the needs of all users. Other conventional technologies such as US Publication No. 2011/0045283, US Publication No. 8,215,972 and US Publication No. 7,354,291 have similar problems.
