Abstract

A mold structure (1) includes a fixed mold (4) and a movable mold (5) for burying, integrally with molding of a plastic molded article (26), a bus bar (3) in which a tuning-fork terminal (32) is provided on a main body circuit unit (31). When the fixed mold (4) and the movable mold (5) are joined together, the terminal base (40) of the tuning-fork terminal (32) is held between a terminal base receiving portion (13) of the fixed mold (4) and a terminal base abutting portion (17) of the movable mold (5) while the tuning-fork terminal (32) is projected outside a cavity which is formed in such a way that the mold main body portions of the fixed mold (4) and the movable mold (5) are joined each other and into the inside of which a resin is injected.

Description

technical field [0001] The present invention relates to a mold structure for manufacturing electrical parts such as a fuse unit by insert molding a bus bar, a molding method using the mold structure, and a fuse unit. Background technique [0002] As described in Patent Document 1, for example, a fusible unit is connected to an on-vehicle battery and wires to supply power to an on-vehicle load, and the fusible unit is installed at a position for receiving the influence of vehicle body vibration. In the position affected by the vibration of the vehicle body, the manufacture is performed by injecting resin in a state where the bus bar with the formed main body circuit unit is inserted into the molding mold in consideration of damage to the unit main body and the bus bar due to resonance. Since the bus bar and the resin molded product are integrated by insert molding the bus bar as described above, resonance due to vibration can be suppressed. [0003] On the other hand, there ...
