摘要： PROBLEM TO BE SOLVED: To provide a connector holder capable of installing several types of connectors. SOLUTION: When a connector 21 is attached to a connector holder 11, a guide part 24 of the connector 21 holds an engagement piece 16 to become a state wherein the inner face of a guide groove 24a is brought into close contact with the outer face of an engagement piece 16a without clearance. Specifically, a lateral face 16b of the engagement piece 16 is brought into close contact with the guide groove 24a without clearance. In addition, an engagement projection 25 is engaged with a cut-out part 16a. This fixes the connector 21 so that it cannot be slipped off from the connector holder 11. Moreover, the guide part 24 of the connector 21 is retained in the engagement piece 16. As a result, the movement of the connector 21 is regulated in the direction of an arrow X (in a direction perpendicular to guide walls 15a).

摘要： PROBLEM TO BE SOLVED: To provide tab terminals having high dimensional accuracy and a branch connection box having tab terminals. SOLUTION: One side walls of respective tab terminals 10 (11 to 16) are punched and formed from a metallic plate 1. The other side walls of the respective tab terminals 10 are punched and formed. At this time, since tip parts 10a of the respective tab terminals 10 are respectively connected by a connecting part 2, the respective tab terminals 10 are not attracted to a press metal mold. An unnecessary part 5 between root parts 10b of the respective tab terminals 10 is punched and formed at once by the press metal mold. Then, the connecting part 2 is cut off from the respective tab terminals 10. Next, when press working is performed on the root parts 10b, a deformation part of the root parts 10b is eliminated, and a cross-sectional shape of the root parts 10b becomes almost a quadrangular shape. When the root parts 10b of the respective tab terminals 10 are bent, the respective tab terminals 10 having no dimensional error can be formed.

摘要： PROBLEM TO BE SOLVED: To avoid a leakage current between bus-bars to which different voltages are applied in an electrical junction box. SOLUTION: Low-voltage system bus-bars, to which a voltage which is not higher than 14 V or not higher than 28 V is applied and high-voltage system bus-bars to which a voltage higher than the voltage applied to the low-voltage system bus-bars and not higher than 200V is applied are provided. The low- voltage system bus-bars and the high-voltage system bus-bars are buried in the same insulating board. The bus-bars to which different voltages are applied are arranged, in a state such that spaces between the bus-bars are filled with resin and tabs of the bus-bars are made to protrude from the surface of the insulating board. The root parts of the tabs are also molded with resin. The bus-bars, to which different voltages are applied are arranged at random on the same insulating board.

摘要： PROBLEM TO BE SOLVED: To provide a male connector which can be assembled completely and a branch connection box which includes the male connector. SOLUTION: A surrounding rib 113 is formed around the male tab hole 105 of a male connector, and its top surface is formed at an inclined surface 1 inclining toward the male tab hole 105. An incorporating rib 2 flush with the surrounding rib 113 is formed in the direction orthogonal to the longer side of the surrounding rib 113. Even if dislocation occurs between a tab 109 and the male tab hole 105, the front end part 109a of the tab 109 comes into contact with the top surface of the incorporating rib 2, so that the front end part 109a of the tab 109 moves smoothly toward the male tab hole 105 of the surrounding rib 113. It is thus possible to guide the tab 109 to the male tab hole 105 completely.
