[0032] The wire assembly includes a terminal and a wire connected to the terminal, the terminal serves as a connecting piece, so that the wire can be conveniently connected with other devices or circuit boards, and is widely used in electronic devices. Among them, when the wire assembly has a plurality of wires, the plurality of wires can be organized together by sleeving and heat shrinking the plurality of wires, so that the wiring is more neat and orderly, easy to identify and manage.

[0033] In the related art, when sleeving two wires, the tail of the two wires deviating from the terminal is prone to slight up-down overlap, and if the subsequent sleeving and heat shrinking process is directly performed, the forming quality of the wire assembly is reduced. The conventional method is to press and clamp the tail of the two wires by using a clamp manually, so that the two wires can be arranged in parallel.

[0034] However, since the clamp is manually operated to clamp the wire, the production efficiency is low.

[0035] In order to solve the above problems, the utility model provides a wire clamping mechanism 10, which aims to realize automatic clamping of the wire 93, prevent the crossing of the plurality of wires 93, and improve the automation efficiency.

[0036] Reference Figures 1 to 6In an embodiment of the utility model, the wire clamping mechanism 10 includes the mounting seat 1, drive piece 21, translation piece 23, first guide piece 31, first clamping assembly 4 and second clamping assembly 5, drive piece 21 is connected in mounting seat 1, translation piece 23 is transmission connected in drive piece 21, to carry out translation movement, first guide piece 31 is connected in mounting seat 1, the side of first guide piece 31 towards translation piece 23 forms first guide surface 311, first clamping assembly 4 is connected in translation piece 23, second clamping assembly 5 is movably connected in translation piece 23, translation piece 23 is driven translation and drives first clamping assembly 4 and second clamping assembly 5 to carry out translation, second clamping assembly 5 is movably abutted in first guide surface 311, and it is towards first clamping assembly 4 movement to carry out clamping action.

[0037] Wherein, the specific structure of wire assembly 90 can refer to Figure 6 Wire assembly 90 can include terminal 91 and two wires 93, one end of two wires 93 is connected to the same side of terminal 91, the other end is generally arranged side by side, and the operation of the other end is carried out together with the two wires 93 through the insulating pipe body 95. It is worth mentioning that in the process of threading the pipe body 95, the tail of the two wires 93 is easily crossed and overlapped.

[0038] In the technical scheme of the utility model, when the wire clamping mechanism 10 is in an inactive state, the first clamping assembly 4 and the second clamping assembly 5 are separated and are away from the side of the two wires 93. When the wire clamping mechanism 10 starts the clamping action, the translation piece 23 of the drive assembly moves, and the first clamping assembly 4 and the second translation assembly move together with the translation piece 23 to move towards the two wires 93.

[0039] In the process of translation of the second clamping assembly 5, the second clamping assembly 5 will be in active abutment with the first guide surface 311, and under the action of the guide force, the second clamping assembly 5 starts to move towards the first clamping assembly 4, and finally realizes the pressing and clamping of the tail of the two wires 93. Since the two wires 93 are fixed at this time, it can be ensured that the two wires 93 will not overlap but be in a parallel arrangement. Once the position adjustment of the two wires 93 is completed, the drive assembly moves reversely to release the tail of the two wires 93, so that the two wires 93 can perform subsequent sleeve heat shrinkage process.

In addition, the presence of the first elastic member allows the clamping force to be automatically adjusted according to the diameter and number of the wires 93, ensuring proper clamping force, neither too tight nor too loose. The first elastic member can also act as a shock absorber to prevent damage to the wires 93 due to excessive instantaneous force during clamping.
