Abstract

A battery connection plate a manufacturing method therefor is provided. A terminal (5) and a busbar (9) are insert-molded in the plate body (2). The terminal (5) is screw-connected to an electrode of a battery with a nut. The terminal (5) is provided with a hole portion and a projecting portion having an opening communicating with the hole portion, and the opening faces in the screwing direction of the nut. Otherwise, the plate body (2) is provided with a pin portion and projections arranged on both sides of the pin portion, and the terminal is provided with a through hole for the pin portion. The projections are positioned adjacently to both sides of the terminal, and the terminal is secured to the plate body (2) by melting the pin portion and the projections and by transforming them. The terminal body is formed integrally with the busbar (9) with use of a metal sheet, and the busbar (9) is formed by double-folding back the metal sheet, wherein the terminal body is connected to the busbar through a narrow portion. The plate body (2) is provided with a pair of guide walls (51,52) having respective slit-like insertion-fixing portions (53,54) to receive the electric wire connected to the terminal (5), and a groove portion (56) for arranging the electric wires is formed between the guide walls.

Claims

1. A battery connection plate, comprising:

a plate body being insulative and moldable; and

a terminal being insert-molded in the plated body and being screw-connected to an electrode of a battery,

wherein the plate body is provided with a pin portion and projections formed on both sides of the pin portion, the terminal is provided with a through hole to put the pin portion therethrough, and the projections are arranged on both sides of the terminal, and

wherein the terminal is secured to the plate body by melting and transforming both of the pin portion and the projections.

2. A manufacturing method of insert-molding a terminal in a moldable insulative battery connection plate, comprising the steps of:

forming a pin portion and projections on both sides of the pin portion on the plate;

forming a through hole to put the pin portion therethrough on the terminal;

positioning the terminal between the projections;

putting the pin portion through the through hole of the terminal;

melting the pin portion and the projection; and

securing the terminal to the plate body by transforming the pin portion and the projection.
