Abstract: Provided is a technology with which, when producing a resin molded article, the inside of which is provided with an insert component such as a terminal fitting, it is possible to prevent the insert component from being exposed at an inappropriate position, and to ensure the desired positional accuracy. In an injection molding device, the accuracy of the position of a terminal is improved by allowing a core-back mold to move after a terminal, which is an insert component, has been inserted in a terminal tip holding section of a slide mold. By allowing the core-back mold to move by only a prescribed amount prior to injection molding, a resin wall is formed between the core-back mold and the terminal. The inappropriate exposure and shorting of and the adhesion of foreign substances to, and the like, the terminal can thus be prevented.

Abstract: The disclosed terminal part can protect the elastic contact portion securely, without increasing the manufacturing cost thereof. The terminal part (43) is formed with a wire connecting portion (3); an elastic contact portion (5); and a top plate portion (49) formed between the wire connecting portion (3) and the elastic contact portion (5). The top plate portion (49) has a lower top plate portion (45) and an upper top plate portion (47). In particular, a lower engage projection (55) formed at the end of the lower top plate portion (45) is engaged with an upper engage hole (57) formed in the upper top plate portion (47), and further an upper engage hook (41) formed at the end of the upper top plate portion (47) is engaged with a lower engage hole (39) formed in the lower top plate portion (45). Therefore, it is possible to securely protect the two side plate portions (13, 15) from being deformed inward even if an external force (F3) is applied to the terminal part inadvertently.

Abstract: The invention relates to a connector terminal and a method of producing the same. The terminal, even if small in size, has a large allowable maximum deflection, and is excellent in durability, and the terminal of a one-part type can be produced from a relatively inexpensive thin metal sheet, thereby reducing the manufacturing cost. More specifically, the terminal is formed from a single thin metal sheet, and has a receptive portion and a spring portion formed at a front portion of a base plate for engaging with a mating terminal, and a wire connecting portion formed at a rear portion of the base plate. The thickness of the spring portion is smaller than that of the remainder of the terminal. In a shaping step of a process including blanking and pressing, only the spring portion is rolled into a thickness smaller than that of the remainder.

Abstract: A resilient connecting part of an electric connecting device is formed by folding back one sheet of metal base into a multilayer, so that the maximum displacement of the resilient connecting part is regulated according to the thickness of the metal base, the number of layers (3 layers) and layer-to-layer gaps.
