Abstract: PROBLEM TO BE SOLVED: To provide the surface of a plating layer with a decomposing action of soil, etc., and with hydrophilic property according to light excitation of photocatalyst grains and to facilitate self-cleaning or water washing with ease by codepositing photocatalyst grains in the metal forming a plating layer and allowing the photocatalyst grains to appear at the surface of the plating layer. SOLUTION: After pretreatment is applied, if necessary, to the surface of a base material 1 of copper alloy, iron, resin, etc., a bright nickel plating layer 2 is formed to about 5-20 μm thickness. Then, a nickel plating layer 4, where photocatalyst grains 3 of titanium oxide, etc., having about 0.01 to several microns grain size are codeposited eutecticly, is formed on the above undercoat plating layer to a thickness of several to several tens microns. This codeposition is performed by adding the photocatalyst grains to a plating solution and immersing the base material in this plating solution. Subsequently, a chromium plating layer 5 is formed on the nickel plating layer 4 to a thickness of 0.1 to several microns.  In this chromium plating layer 5. numerous pores 6 originated from the photocatalyst grains 3 appearing at the surface of the nickel plating layer 4 are formed, by which hydrophilic coating can be obtained.

IPC: H01R13/639
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To simplify the operation and prevent damages to a plug-in part by forming a spring-slide guide mechanism that guides a spring element and has a nonlinear spring characteristics curve. SOLUTION: When a part 2a of a mating receptacle 2 is inserted into a receptacle 1 until it comes into contact with a spring element 3, a bridge part 3d of the sprig element 3 is deflected downward by a deflector 5 of the receptacle 1 and is loosened along the undersurface of the bringing part 2a. When the spring element 3 is loosened, the mating receptacle 2 is fitted in the receptacle 1 with complete connection. At this time, the bridge part 3d of the spring element 3 prevents the mating receptacle 2 from being accidentally unplugged. Thus, by placing the bridge part 3d between the mating receptacle 2 and the holding section 6 of the receptacle 1, the mating receptacle 2 will not be unplugged from the receptacle 1 as long as the bridge part 3d is not deformed actively.
