Abstract: A fuse box has a fuse cavity for receiving the body of a blade type fuse having blade-like male terminals projecting from the body into an insertion direction of the blade type fuse. The body of blade type fuse has opposed ends extending into the insertion direction and a side rib provided on each of the opposed ends and extending into the insertion direction. The fuse cavity has opposed walls for receiving therebetween the opposed ends of the blade type fuse when the blade type fuse is inserted. The fuse cavity also has two pairs of second ribs on the opposed walls, each pair being positioned to define a receiving groove therebetween for receiving the side rib of the blade type fuse.

Abstract: A resilient terminal with a buckling prevention mechanism has a pair of electric contact portions that are interconnected through a flexible joint portion. The flexible joint portion is protected against buckling because an excess bending of the joint portion is blocked by an abutment portion on one of the electric contact portions abutting against the other electric contact portion.

Abstract: A device for locking a pair of connectors to each other, in which a locking unit which is attached to the housing of one of the connectors in a pivotable manner, and is biased by a spring in a direction tending to unlock the connectors from each other. The locking unit includes a pair of support portions and a plate spring engagement portion. Support members are provided on the housing for receiving the support portion and a plate spring is resiliently disposed between the engagement portion and the housing.

Abstract: A resilient terminal with a buckling prevention mechanism has a pair of electric contact portions that are interconnected through a flexible joint portion. The pair of contact portions are provided with abutment portions that are disposed opposite to each other with a small gap therebetween. When there is a misalignment between the mating terminals or when an excessive insertion force is applied, the flexible joint portion of the terminal deflects to allow the male terminal to be inserted therein. The flexible joint portion, however, is protected against buckling because an excess bending of the joint portion is blocked by the abutment portions abutting against each other. At the same time, one of the abutment portions slides on the other, correcting the terminal misalignment and ensuring reliable terminal engagement.

Abstract: A dielectric ceramic material essentially consists of a complex perovskite compound mainly composed of Ba(Mg.sub.1/3 Ta.sub.2/3)O.sub.3 phase and 0.005 to 1.0% by weight of phosphorus with reference to the complex perovskite compound.As one of the dielectric properties, the unloaded Q value reaches 37000 at a measuring frequency of 10 GHz and the temperature coefficient of the resonant frequency is about 4 ppm/.degree.C.

Abstract: The electric junction box of this invention has a plurality of connector receiving sockets mounted on its insulating box. Selected one of the connector receiving sockets, or the first connector receiving socket, is attached with a locking cover, which is urged by a spring to lie flat over the adjacent or second connector receiving socket. A first connector can be assembled onto the first socket but a second connector cannot be connected to the second socket unless the locking cover is erected and locked onto the first connector. To rule out the slightest possibility of erroneous connection sequence, a connection sequence check member is provided to the second connector.

Abstract: A wire harness assembly is disclosed in which a wire harness having a primary wire bundle and a plurality of branch wires branched from the primary wire bundle is received in a wire protective casing composed of a casing body and a casing cover along with the arrangement configuration of the wire harness. A plurality of engagement holes are formed in the protective casing, corresponding to connectors provided at terminal ends of the branch wires. Cushion arms that are engaged with the engagement holes are formed on outer walls of housings of the connectors, so that the connectors are displaceable relative to the engagement holes.

Abstract: A protection cover for a wiring distribution box in which rising walls are continuously or discontinuously formed around a label bonding position.

Abstract: A watertight and leak-proof junction box for use, for example, in vehicles such as automobiles, and a process of assembling such a junction box are provided. The wiring board assembly comprising a plurality of insulating plates, wiring conductors strips and electric contacts formed by raising the free ends of the strips so as to project from the outer surface of the wiring plate pile which is embedded in an insulating resin through molding to form a resin-embedded wiring board assembly prior to assembling the junction box, and then the resin-embedded wiring board assembly joined with a connector support board having connector bodies for receiving the terminals of electrical units and/or wire harnesses is contained in a watertight case.

Abstract: A sealing material receiving structure in a junction block for use on a vehicle or the like is provided. The junction block comprises a top cover provided with a connector or connectors, or a wiring board; a bottom cover provided with a connector or connectors, or a wiring board; an insulating plate or plates provided with bus bars having tab terminals, and placed between the top and bottom covers; and an elastic plate-shaped packing placed between the lowermost insulating plate and the bottom cover. Rectangular enclosures are formed integrally with the packing so as to surround holes for receiving the tab terminals formed in the packing. Holes for receiving the enclosures therein, respectively, are formed in the bottom cover.

Abstract: An ultra multi-pole connector includes a plurality of small size multi-pole connectors each having a connector housing which has a plurality of terminals connected to a plurality of wires therein and engagement shoulders projecting from the upper portion of the connector housing, and a casing having a plurality of hollow sections to which said small size multi-pole connectors are mounted, respectively, and each of said hollow section having an engagement members, thereby the small size multi-pole connectors can be displaceably mounted in the hollow sections by engagement of the engagement shoulders and the engagement members.

Abstract: Disclosed is a cylindrical closed strainer molded of a plastic in a unitary structure, which comprises a top plate, a bottom plate disposed opposite said top plate at a fixed interval therefrom and a cylindrical net stretched between the peripheries of said top plate and bottom plate, said top plate being possessed of snap fastening means on the upper surface thereof and provided with a through hole which has a diameter larger than the outside diameter of a suction pipe intended to be connected with the strainer body and is provided on the inner circumference of said through hole with a thin seal member coaxially containing a circular hole of a diameter smaller than said outside diameter of the suction pipe. Said suction pipe is provided with a flange which is adapted to rest stably on the upper surface of said top plate.

Abstract: Disclosed is a strainer which is suitable for use in supplying gasoline from a gasoline tank by means of a suction pipe. A strainer according to this invention comprises a cylindrical body having a net applied to the periphery thereof and a cover which is adapted to closely cover the top opening of the cylindrical body. The cover has an annular projection around the through hole at the center. In use, the cover is fit onto the top opening of the cylindrical body and then the end of a suction pipe is inserted in the cylindrical body through the annular projection.The structures of the cylindrical body and the cover are amenable to production by injection molding, and are easy to assemble.

Abstract: Disclosed are a strainer and a method of injection-moulding the strainer of plastics. A strainer according to this invention comprises a pair of semi-cylindric shells integrally and movably connected along their adjacent longitudinal sides in the state of being developed; top and bottom circular boards integrally connected to the top and bottom frames of one of said semi-cylindric shells; and nets integrally connected to each of said semi-cylindric shells. This developed structure of the strainer makes it possible to injection-mould a semi-product of strainer as a whole in a single injection-mould die, and a so moulded and developed strainer is easily assembled in the final and complete cylindric shape by simply closing the semi-cylindric shells and integrally connecting them along their abutting longitudinal sides.
