Abstract

PURPOSE:To facilitate making of a connector or a terminal by the use of such a way that when bodies where a plurality of conductive members are arranged at intervals are divided into individuals which include one conductive member respectively, a kerf is made in the surface of the body to be used for dividing the body into the individuals. CONSTITUTION:A plurality of conductive members 10b are installed in parallel with each other on a terminal 40 or an electrical parts line, and held by a body 30 made up of insulating material. Both ends of the respective conductive members are bent downward to form projecting parts 10d, and then, a total of the depths L1, L2 of the projecting parts 10 adjacent to each other is made equal to the interval L3 between the adjacent members 10b. Thus, the sections between the adjacent members 10b are electrically kept insulated, and a kerf 30a as a means of notching is cut in the surface of the body 30 corresponding to this insulated section to make it possible to divide the body 30 including the projection portions 10 into individuals, so that a work to divide the electrical parts arranged in a line into connectors, terminals, etc., can be simplified.

During this resin molding, through-holes arranged in rows are simultaneously formed. Next, a conductive member is inserted into each through hole of the main body and fixed.

In this way, the terminal was completed.

[Problems to be Solved by the Invention] However, the above conventional techniques have the following problems.

First, it was necessary to manually fit the conductive members into the main body one by one, which was a complicated and time-consuming process. As a result, the conductive member may bend during operation, making insertion difficult, or causing wobbling in the conductive member after insertion.
This also caused a decrease in contact reliability.

Second, if the conductive member is inserted using an automatic machine, the above-mentioned problems will disappear, but a new problem arises in that the automatic machine requires a large cost.
