A female terminal, including: a female terminal fitting including a connector to be conductively connected to a male terminal; a male terminal inserting tube provided in the female terminal fitting, the male terminal being press-fit into the male terminal inserting tube, the male terminal inserting tube forming the connector by an inner surface; a pair of overlapping plates connected to a pair of first divided portions provided by dividing the male terminal inserting tube over an entire length in an axial direction at one position in a circumferential direction, the pair of overlapping plates being separated from each other and projecting outward; and a spring held on the female terminal fitting, the spring holding the male terminal inserting tube in a reduced diameter state by biasing the pair of overlapping plates in a direction to overlap the pair of overlapping plates on each other.

A connector includes a housing in which a terminal fitting is stored, and a cover. A guiding structure configured to guide the housing and the cover in a connection direction, and a holding structure configured to hold the housing and the cover at a connection completed position are provided between the housing and the cover. The guiding structure includes a wedge guiding protrusion provided to the cover, and a wedge guiding groove provided to the housing. The wedge guiding protrusion and the wedge guiding groove are formed to have a gap between a protrusion-side wall surface and a groove-side wall surface disposed opposite to each other in each of two pairs. The holding structure includes a press-fit protrusion being configured to hold the wedge guiding protrusion and the wedge guiding groove in a press-fitted state when the housing and the cover are at the connection completed position.

A male terminal 40 to be accommodated into a cavity 12 of a housing 11 includes a plate-like tab 49 formed in a front end part, and a box portion 41 in the form of a rectangular tube connected to a rear part of the tab 49 and open rearward. A first projection 42 projecting in a thickness direction of the tab 49 is formed on one plate surface of the tab 49, and press-fit to an inner wall of the cavity 12 of the housing 11 from behind.

A receptacle connector having a stable contact point structure and a rigid structure, and a connector assembly including the same, is provided. The receptacle connector includes a receptacle housing, a plurality of receptacle terminals which are retained and supported in the receptacle housing in a first direction, and one pair of receptacle metal members which are provided on both ends of the receptacle housing in the first direction.

An electric connection member including: a bus bar that has at least one terminal portion; a primary molded portion formed in one piece with the bus bar in a state where the terminal portion is exposed; a secondary molded portion formed in one piece with the primary molded portion; and a seal member embedded in the secondary molded portion, wherein the primary molded portion includes an exposed portion that is exposed from an opening portion provided in the secondary molded portion, the seal member is shaped to surround the circumference of the exposed portion without a gap, and a boundary portion of the seal member to the secondary molded portion is heat sealed to the secondary molded portion.

A housing tool that houses an intersecting terminal metal fitting with an electric wire includes a first housing member and a second housing member integrated by fitting cylinder opening parts to each other in an inserting manner. The first housing member includes a first housing chamber that houses a terminal connection part of the terminal metal fitting, a terminal insertion port, and an opening of an opening part of the first housing member through which the terminal metal fitting at an electric wire connection part side is drawn out to the outside. The second housing member includes a second housing chamber that houses the electric wire connection part drawn out from the opening with the end of the electric wire, an electric wire drawing port, and an opening of an opening part of the second housing member through which the terminal metal fitting is drawn out.

A receptacle connector having a stable contact point structure and a rigid structure, and a connector assembly including the same, is provided. The receptacle connector includes a receptacle housing, a plurality of receptacle terminals which are retained and supported in the receptacle housing in a first direction, and one pair of receptacle metal members which are provided on both ends of the receptacle housing in the first direction.

A plug connector having a housing, a holding frame, which is situated at least partially inside the housing and is fastened thereto, as well as a number of plug connector modules, which are held in the holding frame, at least one separate supporting element being disposed in an intermediate area between the housing and the holding frame, which supports the holding frame and thus protects it against a critical deformation.

A housing that can be used for a power module in a power system is disclosed. The housing includes features to improve the insulating properties and to reduce or eliminate a mechanical stress on a housing that could crack or break a substrate contained within the housing. The insulating properties are improved by protrusions that surround apertures for press-fit pins. Each protrusion can increase a creepage for the housing by extending the surface of the housing along a press-fit pin. The mechanical stress is reduced by a mounting flange that includes a wedge surface and a flexible structure that react to a force applied when the mounting flange is fastened to a surface by a fastener.

The present disclosure disclosed a conductive slip ring including a first terminal group and a second terminal group. The first terminal group includes a first terminal and a second terminal. The first terminal has a first contact portion provided with a first annular contact surface. The second terminal has a second contact portion provided with a second annular contact surface. The second terminal group includes a third terminal and a fourth terminal. The third terminal is in rotating contact with the first annular contact surface of the first terminal. The fourth terminal is in rotating contact with the second annular contact surface of the second terminal. The first annular contact surface and the second annular contact surface are spaced apart from each other along an axial direction of the conductive slip ring. As a result, structure of the conductive slip ring can be made in a more compact manner.
