Description

Technical Field

[0001] The invention relates to the technical field of fixing devices, in particular to a fast connection terminal fixing device. Background Art

[0002] Terminal blocks are an accessory product used to achieve electrical connections, and are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks is gradually increasing.

[0003] Taking into account the gradual increase in the application of terminal blocks in actual use, and the increase in the number of terminals in use, it is necessary to fix the terminal heads with a fixing structure, thereby effectively preventing the terminal heads from separating from the socket strips. At this time, some terminal fixing devices with special structures and functions can be used.

[0004] Generally, during the use of traditional terminal fixing devices, a single terminal needs to be clamped and fixed or directly plugged and fixed by friction. The clamping and fixing method will increase the number of operations when fixing multiple terminals, which will cause a waste of time and reduce the clamping efficiency. If the friction force is directly clamped, the deeper the insertion, the more laborious it will be, which will increase the time and efficiency of plugging and unplugging, which is very inconvenient. After the terminal wires are fixed, they will become entangled when there are a large number of them, which will increase the subsequent sorting costs. At the same time, they are easy to break free and separate, which is very inconvenient.
