Abstract

A connection structure of a screw block is provided, wherein a screw member and a bus bar are arranged in one side of an insulating screw block body, a power circuit is threadedly connected to the bus bar by the screw member, and the terminal portion of the bus bar is accommodated in the screw block body. In the inner space of , wire-equipped terminals for power distribution are accommodated in the inner space from the other side of the screw block body, and the wire-equipped terminals and the terminal portion of the bus bar are connected to each other.

Description

technical field [0001] The present invention relates to a connection structure of a screw block for screwing a bus bar or a terminal equipped with an electric wire to a junction box or the like mounted on a vehicle or the like, and connecting another by using a connector or the like Equipped with wire terminal. Background technique [0002] In order to screw a bus bar made of conductive metal and located in a junction box to an external wire-equipped terminal with fastening of a bolt and a nut, various screw connection structures have been proposed. [0003] For example, Patent Document 1 discloses a configuration (not shown) in which a protector additional arrangement portion is formed on a vertical side wall of a junction box body made of synthetic resin with a bottom, and the protector is cut off. The upper end portion of the additional arrangement part of the device, in which a pair of left and right bus bars (in the junction box body) are arranged in parallel, the bus ...
