Terminal crimping method, terminal crimping device, and terminal-crimped electric wire manufacturing apparatus

Abstract

Provided are a method and a device for crimping a terminal onto the uncoated end portion of an electric wire so that the electric wire may not be ridged or folded when crimped. The terminal crimping device comprises an applicator (10) and a clamp device (50) for holding and moving an electric wire (E) upward and downward. The applicator (10) includes crimpers (13 and 15) and anvils (14 and 16) acting as crimping tools, a slide cutter (17) for cutting a connecting portion between a terminal and a band body, and a cut-off punch (18) for pushing down the slide cutter (17). At the terminal crimping time, the electric wire (E) is moved at first by the clamp device (50) downward to the height position (H2') of the upper face of the slide cutter. After this, the crimpers (13 and 15) are moved downward, while the electric wire (E) is being moved by the clamp device (50) downward to a crimping height position (H1), thereby to crimp the terminal onto the end portion of the electric wire, and the slide cutter (17) is moved downward to cut off the terminal from the band body. As a result, the electric wire (E) is crimped / cut while being substantially straight.

Description

technical field [0001] The invention relates to a method and a device for crimping a terminal to the end of an electric wire whose sheath has been stripped off. In particular, it relates to a method and an apparatus for crimping terminals one by one to an end portion of an electric wire from a strip formed by connecting a plurality of terminals in parallel to a strip-shaped carrier. It also relates to an electric wire manufacturing device with crimp terminals, which cuts electric wires to a predetermined length and crimps terminals to both ends thereof. Background technique [0002] Next, a general terminal crimping device currently used will be described first. [0003] The terminal crimping device is mounted on a terminal crimping wire manufacturing device for crimping terminals to both ends of an electric wire of a desired length. Here, a description will be given of a terminal crimping device having a side-feed applicator that supplies a tape in which a plurality of te...

Problems solved by technology

[0058] In addition, when the shape and size of the terminal to be crimped or the wire is changed, the height position of the stopper must be adjusted, which will subtly increase the time-consuming and laborious work
