The present disclosure provides a terminal block that can be kept compact. A terminal block has a housing made of a synthetic resin, a columnar metal connection terminal held by the housing, and a cylindrical metal joint part in which a device connection part of the connection terminal is inserted. The joint part has a cylindrical part in which the device connection part is inserted and a cylindrical part in which an end part of a device-side terminal electrically connected to the connection terminal is inserted. The connection terminal is electrically connected to the device-side terminal via the joint part.

Joint portion connecting a terminal block connection terminal with a counterpart terminal

A connection terminal for connecting a first conductor and a second conductor, the connection terminal including: a connection configured to be connected to the first conductor; an arc-shaped fitting that extends from the connection, and is configured to be fitted to, while being in surface contact with, a tubular outer circumferential surface of the second conductor over a half of the circumference thereof, with application of restoring force after elastic deformation; and a pair of extensions that extend from two ends, in a circumferential direction, of the arc-shaped fitting, and are curved to a side opposite to a side to which the arc-shaped fitting is curved.

Connection terminal and terminal connection body

An electric device terminal apparatus includes: a housing having a fitting portion that can fit together with a partner member; a storage groove provided in the periphery of the fitting portion, on an end surface of the housing that faces the partner member; and a ring-shaped seal member that is provided in the storage groove and water-tightly seals a space between the end surface of the housing and the partner member. The storage groove is filled with a liquid gasket as the seal member.

Electric device terminal apparatus and method for manufacturing electric device terminal apparatus

When forming molded resin on a terminal-equipped conductive wire, cases where resin inside the mold for insert-molding leaks out from the mold are suppressed. A smooth portion having a smooth outer circumferential surface is formed in a conductive wire of a terminal-equipped conductive wire (smooth portion formation step (S)). Furthermore, a molded resin member that covers the terminal connection portion is formed in a state where the terminal connection portion provided is inserted into an insert-molding mold, and a portion of the conductive wire that extends from a metal terminal is exposed to the outside through an opening portion of the mold (insert-molding step (S)). The outer shape of the smooth portion is a shape that corresponds to the opening shape of the opening portion of the mold. In the insert-molding step (S), the interior of the mold is filled with a resin in a state where the inner circumferential surface of the opening portion of the mold is in contact with the outer circumferential surface of the smooth portion.
