A female terminal which enables a tab of a male terminal to be fitted into a female terminal even if the tab is bent when a connector housing receiving the male terminal is fitted relative to a connector housing receiving the female terminal. An elastic engagement arm is provided within a terminal receiving chamber in a connector housing. A female terminal includes a fitting portion for receiving a male terminal, an engagement portion for being retained by the engagement arm, and a wire connection portion. A guide projection is formed on the fitting portion of the female terminal, the guide projection projecting forwardly beyond the front end surface of the female terminal. There is provided a slanting guide surface extending from the guide projection 18 to an inlet of the fitting portion. A groove for allowing the passage of the guide projection therethrough is formed in the engagement arm.

An object of the present invention is to provide a housing block retaining construction which allows a release tool to be easily operated, and will not interfere with the withdrawal of a housing block. According to the present invention, there is provided that a housing block retaining construction comprises a retaining lance slanting in the insertion direction provided in an insertion opening of a housing holder, a notch in which a distal end of a release tool is engageable formed in a distal end of the retaining lance, a retaining projection for engagement with the retaining lance provided on a housing block, and a recess for allowing the release tool to pass therethrough formed in that portion of the retaining projection corresponding to the notch.

A female terminal comprises: a square cylindrical electric contact portion (2) having an opening (2a) into which a male terminal is inserted: an elastic contact piece (3) housed in the electric contact portion and brought into elastic contact with the inserted male terminal, the elastic contact piece being formed with two side lug portions (10); and at least one supporting portion (14) formed on at least one of side walls of the electric contact portion, for supporting at least one of the lug portions formed in the elastic contact piece. For prevention of the elastic contact piece (3) from being dislocated from the supporting portion (14) without increasing the external size of the female terminal, in particular, the supporting portion (14) is elastically bent inwardly from the side wall (7) of the electric contact portion (2).

A female terminal includes a terminal body, comprised of a first material having excellent corrosion resistance and an elastic piece, comprised of a second material having excellent spring properties, and the elastic piece mounting on the terminal body. An engagement portion is formed on the terminal body. A retaining portion is formed on the elastic piece. The retaining portion is engaged with the engagement portion so that the elastic piece is mounted on the terminal body.

A method for producing a fuse element having a fusible portion and any other portion which are made of different kinds of metal. The method comprises the steps of boring through-hole in a substrate made of first metal, forming an element plate by fusion-bonding a second metal to the through-hole and integrally stamping a pair of substrate portion made of the first metal and a low-melting-point portion made of the second metal. The second metal is made of a metal whose melting point is lower than that of the first metal. Further, the pair of substrate portion is connected together by the low-melting-point portion so that the fuse element is formed.

A fuse comprising: a fusible portion constituted by a connection portion which is formed of the same metal base material as a pair of terminals so as to connect the pain of terminals to each other, and a low-melting metal having a melting point lower than that of the connection portion and stacked by welding on at least a portion of the connection portion; and at least one protrusion formed on the fusible portion by making the connection portion and the low-melting metal project in a direction parallel to the plane of an interface between the connection portion and the low-melting metal. Further disclosed is a method of manufacturing the fuse. The fuse can be manufactured with a simple manufacturing process in comparison with a conventional method, and in the fuse, only the fusing-off time in a layer short-circuit range can be shortened by use of diffusion between the low-melting metal and base material.

A low insertion-withdrawal force electric connector is disclosed wherein a pin is mounted on one side wall of a male housing; a groove into and out of which said pin is movable is provided in a hood of a female housing; a cam lever is pivotally mounted on said hood; and the cam lever has at its front end an eccentric cam groove which is engageable with the pin so as to cause said two housings to be fitted and disengaged relative to each other in response to the pivotal movement of said lever. A fitting-side acting surface of the eccentric cam groove against the pin is disposed generally perpendicular to the direction of advance of said pin when the two housings are completely fitted together.
