A female terminal includes an electric contact portion that has a cylindrical box portion and an elastic contact spring disposed in the inner part of the box portion. An abutment portion of the metal plate is disposed on the upper wall portion of the box portion, and an indent is formed, from the outside of the box portion, at the upper wall portion having the abutment portion disposed thereon. A projection portion is provided at the inside of the box portion, and an apex of the projection portion is made to be a contact portion with respect to the male terminal.

Female terminal for connector

A fixing bracket for fixing a housing on a board includes: a placing portion configured to be placed on the board; an attaching portion configured to be attached to the housing; and a retaining portion which retains the placing portion to the board. The placing portion may include a receiving portion which accommodates the retaining portion.

The goal is to enhance the productivity by reducing the cost of a die. A method for selectively forming a female terminal () and a male terminal (), each terminal having a square tubular box portion () in its front and a wire crimping portion () in its rear, from blanks () punched into a common shape is provided. In a step of punching the blank, a front projection () which becomes a spring piece () when the female terminal is produced and becomes a male tab () when the male terminal is produced is projected from the front end of a strip-like base plate () constituting a bottom plate of the square tubular box portion, and a blank in which right and left projections () constituting the wire crimping portions are projected is formed in the rear of the base plate. In the subsequent pressing step, the female terminal and the male terminal are selectively formed in response to whether the front projection () is folded backward or left as it is, while the blank is made common for the box portions.

Method for producing terminals

A seal structure includes a housing and a waterproof member provided in the housing. The waterproof member includes a body and electric wire insertion holes formed in the body for passing through electric wires respectively. Each of the electric wire insertion holes has a first insertion part and a second insertion part. An inner diameter of the second insertion part is larger than an inner diameter of the first insertion part. The first insertion part is adapted to hold a first electric wire and the second insertion part is adapted to hold a second electric wire. An outer diameter of the first electric wire is larger than an outer diameter of the second electric wire. An elastic portion attached to an outer periphery of the second electric wire is positioned at the first insertion part or the second insertion part in an intimate contact state.

Seal structure

A connector which can be made small is provided. The connectorincludes: a connector housingreceiving terminal fittingsarranged in rows, the terminal fittingattaching an electric wirethereto; and a holding partincluding a plurality of molded membersmolded integrally with an outer periphery of the electric wires; and a packingattached to an outer periphery of the holding partand sealing up a space between the holding partand the connector housing

Connector

A rubber stopper for a waterproof connector includes: a first elastic member including a first contact face, and first wire fitting grooves each having an arc cross-section; and a second elastic member including a second contact face and second wire fitting grooves each having an arc cross-section. When the first contact face contacts the second contact face, circular cross-section is formed by the arc cross-sections of the first and second wire fitting grooves to fit wires into the first and second wire fitting grooves. Arc length of the arc cross-section of the first wire fitting groove is different from arc length of the arc cross-section of the second wire fitting groove so that a center of the circular cross-section is disposed away from the first and second contact faces in a direction perpendicular to an extending direction of the first and the second contact faces.

Rubber stopper for waterproof connector and waterproof connector

A connector includes a first and a second terminal portions each having: a substrate pressing portion; a spacer pressing portion; and a fulcrum portion arranged between the substrate pressing portion and the spacer pressing portion, a spacer arranged between the spacer pressing portions of the first and the second terminal portions, and a clipping section formed of the substrate pressing portions of the first and the second terminal portions. The clipping section opens and closes while operating the fulcrum portions as a fulcrum. The spacer pressing portions of the first and the second terminal portions close via the fulcrum when the clipping section opens.
