Description

Technical Field

[0001] This utility model relates to the field of crimping device technology, specifically a wire terminal crimping device. Background Technology

[0002] Terminal blocks are used to facilitate the connection of wires. They are actually a metal sheet encased in insulating plastic with holes at both ends for inserting wires and screws for tightening or loosening. For example, if two wires need to be connected and disconnected at other times, they can be connected with terminals and disconnected at any time without having to solder or twist them together, which is very convenient and quick. However, when crimping terminals, a crimping device is needed to assist in the crimping operation.

[0003] For example, application number 202220150006.7 discloses a wire terminal crimping device, including a base, a lower die base, and an upper die base. The lower die base is installed on the base and is provided with a positioning platform. The positioning platform is used to position the terminal conduit. The lower die base is equipped with two first pressing knives, which are symmetrically arranged on both sides of the positioning platform. The upper die base is slidably installed on the base in the vertical direction and is located above the lower die base. The upper die base is provided with two second pressing knives. The second pressing knives cooperate with the positioning platform to crimp the conduit. The upper die base is also provided with two driving blocks. The two driving blocks are used to drive the two first pressing knives to move towards each other to crimp the conduit. During the pressing process of the upper die base, the two first pressing knives and the two second pressing knives can simultaneously crimp all the conduits of the terminal, thereby simultaneously crimping multiple wires and terminals, effectively improving the processing efficiency of the terminals.

[0004] However, while this type of wire terminal crimping device can crimp terminals well, it is often not very effective at cleaning impurities adhering to the surface of the terminal connection area, and the cleaning block is not easy to disassemble and replace, thus affecting the connection quality of the terminals.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a wire terminal crimping device. Utility Model Content

[0036] Working principle: When using this wire terminal crimping device, firstly, when the crimping device crimps the terminal, in order to improve the convenience of cleaning impurities adhering to the terminal surface and improve the connection quality, the micro motor 15 can be turned on to drive the worm wheel 17 to rotate through the rotation of the worm gear 16. The movement of the worm wheel 17 drives the rotating rod 18 to rotate, and through the connection of the limiting groove 21, it drives the adjusting block 19 to slide along the inner wall of the adjusting groove 20, thereby driving the telescopic rod 22 to extend and retract along the outer wall of the clamping block 14. Through the setting of the cleaning sponge 24, it drives the cleaning block 23 to reciprocate along the surface of the terminal, realizing the control operation of conveniently cleaning impurities adhering to the terminal surface before crimping.

[0037] Finally, when the cleaning block 23 is used for a long time, in order to improve the convenience of disassembling and replacing the cleaning block 23, the connecting block 29 can be slid into the inner wall of the mounting box 25 through the connection of the locking block 30.
