Description

[Detailed description of the invention] (Industrial application field) The present application relates to a crimp terminal connection tool, and aims to quickly and surely crimp a crimp terminal and save labor in connection work.

(Prior Art) As is well known, a crimp terminal is used for connecting an electric wire in an electric wiring work. Various types of crimp terminals are used depending on the purpose of use. For example, for short-circuit wires, terminals as shown in FIGS. 6 and 7 are used.

That is, the female terminal 1 is formed by reinforcing both sides of the substrate 10 in an arc shape to form a reinforcing rib 9, and the male terminal 2 described later between the tip of the rib 9 and the substrate 10. The fitting gap 11 into which the joining piece 14 fits is formed. An electric wire 13 is connected to the terminal 1 via a predetermined connecting means 12.

A rib 9a is formed on the male terminal 2 in the same manner as the terminal 1, and a tip of the substrate 10a is bent and extended in a U-shape to form a tongue-shaped joining piece 14. An electric wire 13 is similarly connected to the terminal 2 via a connecting means 12.

Conventionally, when both terminals 1 and 2 having such a configuration are crimped, as shown in FIG.
Each was gripped by a gripping tool 8 such as a pair of pliers and crimped, or held by hand and crimped as shown in FIG.
