AI Technical Summary
The existing automotive connector terminal crimping device requires the removal of the protective plate when dealing with equipment problems and changing molds, which makes operation inconvenient.
The push block and L-shaped mounting plate are driven by a telescopic cylinder. The slide block moves on the slide rail, causing the protective plate to offset the terminal crimping mechanism. This eliminates the need to disassemble the protective plate, making it convenient to handle problems and change molds.
This allows for timely handling of equipment malfunctions or mold replacements, avoiding unnecessary disassembly steps and improving operational convenience.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of terminal crimping technology, specifically a crimping device for automotive connector terminals. Background Technology
[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-formed contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connecting circuit. The body wiring harness connects the entire vehicle body and is generally H-shaped. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wire harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments. During production, connecting wire harnesses requires cold pressing or hot welding to connect the ends of the wire harness to external terminals, with cold pressing being the most common connection method.
[0003] A search revealed a terminal crimping device for safety protection, as disclosed in announcement CN210779429U. Its main features include: a base, a crimping head for crimping terminals within the base, a foot switch and a hand switch connected to the base for controlling the crimping action of the crimping head, both the foot switch and hand switch being connected to the base via wires, a clamping device for holding terminals and wires on the base, a protective plate on one side of the base for wires to pass through and for protection, a through-hole groove on the protective plate, an adjusting plate for positioning the wires within the through-hole groove, and a spring connecting the adjusting plate to the top wall of the through-hole groove.
[0004] In actual use, the applicant found that while the aforementioned terminal crimping device protects personnel from being pinched during the crimping of automotive connector terminals, equipment problems and the need for subsequent terminal mold replacements are inevitable during actual crimping operations. The protective plate is typically fixed in place with screws, requiring separate disassembly for handling equipment issues and mold replacements. This hinders timely equipment problem resolution and increases the need for mold replacements, making it inconvenient in practical use. To address these issues, an automotive connector terminal crimping device is proposed. Utility Model Content

A crimping mechanism for automotive connector terminals is installed on the machine table. A telescopic cylinder is fixedly connected to the bottom surface of the machine table. A push block is fixedly connected to the piston rod end of the telescopic cylinder. An L-shaped mounting plate is fixedly connected to the push block. A slider is fixedly installed on the upper part of the L-shaped mounting plate. A slide rail is fixedly installed on the machine table. The slider is slidably connected to the slide rail. A protective plate is fixedly installed on the top of the L-shaped mounting plate by bolts. The protective plate is located at the front feeding point of the terminal crimping mechanism.
[0007] In a preferred embodiment, the protective panel is made of transparent acrylic material.
[0008] In a preferred embodiment, the protective plate has a wire hole.
[0009] In a preferred embodiment, a strip-shaped hole is provided on the equipment platform, and the L-shaped mounting plate passes through the strip-shaped hole.

[0013] 1. In this utility model, when the terminal crimping mechanism malfunctions or the crimping mold needs to be replaced during operation, the telescopic cylinder can be activated to drive the L-shaped mounting plate on the push block to move on the slide rail via the slider, thereby causing the protective plate to shift off the terminal crimping mechanism. This facilitates timely handling of problems and subsequent replacements, eliminating the need to repeatedly disassemble the protective plate and making daily operation of the equipment more convenient.
