Abstract: An electrical connector comprises an insulating housing having contact receiving openings that receive contacts. Housing lances extend into the contact receiving openings and engage the contacts to perform a primary locking function of the contacts. A retainer is mounted to a front surface of the housing. The retainer has tool insertion openings communicating with the contact receiving openings. The retainer is moveable between a temporary locking position and a main locking position. The retainer is locked to the housing in both the temporary locking position where the contacts are insertable into the housing and the main locking position where the retainer performs a secondary locking function of the contacts.

Abstract: There is provided a male contact having improved electrical contact reliability with a female contact. The male contact has a mating section capable of being formed compactly using a plate member having a plate thickness satisfying a desired strength requirement. The male contact 1 has a mating section 10 formed in such a manner that two plate members 11 and 12, which individually extend from a base 20, are superimposed on one another by folding on the base 20. The mating section 10 has flat sections 15 extending in a mating direction P, wherein outer surfaces of the two plate members 11-1 and 12-1 are formed flat. A tip 13 of one of the two plate members 12 is folded to overlap a tip 14 of the other plate member 11. This feature makes it hard to open the plate members 11 and 12 when the male contact is mated with the female contact.

Abstract: The invention relates to a waterproof grommet having a first member (20) and a second member (30). The first member (20) has a first sealing part (22) formed on the inner surface of a through-hole (21) through which an electrical wire connected to a contact is passed. The first sealing part (22) adheres tightly to the electrical wire. The second member (30) has a second sealing part (32) formed on the outer surface of the through-holes (21) that adheres tightly to the connector housing (40). The first member (20) is formed from an elastic material that has a lower hardness than that of the second member (30). As a result, splitting of the inner surface of the through-holes (21) is prevented without causing any deterioration of the waterproof properties of the joint between the connector housing and the waterproof grommet.

Abstract: A male contact having a male contact section formed by bending both sides of a metal plate inward and a method for manufacturing the same. The male contact section having a substantially rectangular cross-sectional shape and curved sections formed on four corners of the cross-sectional plane of the male contact section having a radius that is equal to or less than ⅓ of the thickness of the metal plate. The male contact makes it possible to obtain a sufficient area of contact with a mating female contact even in cases where the width of the male contact section formed by bending both sides of the metal plate inward is small.

Abstract: There is provided a male contact which is high in reliability of an electric contact with the female contact and has a mating section capable of being formed with compactness using a plate member having a plate thickness satisfying a desired strength. The male contact 1 has a mating section 10 formed in such a manner that two sheets of plate members 11 and 12, which individually extend from a base 20, are superposed on one another by folding on said base 20. Said mating section 10 has flat sections 15 extending in a mating direction P, wherein outer surfaces of said two sheets of plate members 11-1 and 12-1 are formed flat. A tip 13 of one 12 of said two sheets of plate members is folded to overlap a tip 14 of another plate member 11. This feature makes it hard to open the plate members 11 and 12 when the male contact is mated with the female contact.

Abstract: The present invention provides a relatively compact electrical connector which is equipped with a resilient latching mechanism (21) on one side of a housing (20), and which accommodates a plurality of different types of electrical contacts inside the housing. The housing (20) of the electrical connector (10) has relatively-small first cavities (30a) which accommodate electrical contacts (60) that have contact lances (61), and relatively-large second cavities (30b) which have housing lances (57) used to latch electrical contacts (70). Mold-release apertures (54) used to form the housing lances (57) are located inside rigid walls (81) that protect the resilient latching arm (21) from both sides and mold-release apertures (44) used to form latching shoulders (43) are located in another side of the housing opposite the one side of the housing.

Abstract: A waterproof electrical connector comprises a structure intended for the reduction of air pressure trapped inside the connector during its coupling with a mating connector. The waterproof electrical connector (10) has a waterproof-sealing member (50) retained by an inner housing (20) and an outer housing (30). In a cavity (55) of a wire-sealing section (53) of the waterproof-sealing member (50), a deformable elastic thin-wall partition (56) is provided. The thin-wall partition (56) is deformed when the connector is coupled with a mating connector, thus reducing the air pressure inside the connector.

Abstract: The purpose of this invention is to provide an electrical connector for attachment to post-type terminals of electrical equipment which would allow for an easy attachment to the terminals and would cover the terminals in a fully-connected state. This is accomplished by a terminal (22) made by bending a blank stamped from a conductive sheet material and it comprises a first tubular section (22a) in which a core (21a) of cable (21) is secured by crimping and of a second tubular section arranged approximately perpendicularly to the first tubular section. The terminal (22) mounted to an inner housing (23) and the cable core (21) secured thereto are enveloped in an outer housing (26) by an over-molding method. The outer housing (26) has openings (26c) which engage latching arms (13) of the battery (10) when the second tubular section (22b) is placed over the post-type terminal (11).

Abstract: The front section (2) of the waterproof plug (1) has an opening (10) of a small diameter, and its rear section (8) has an opening of a large diameter. When the waterproof plug (1) is placed over the wire with its conductor (94) exposed by stripping the insulation (92) from the end of the wire, the small diameter opening (10) and the large diameter opening (12) fit tightly over the conductor (94) and the insulation (92), respectively. A pin contact (40) is attached to the wire tip (96) by crimping, and the waterproof plug (1) is retained between the crimping section (46) of the pin contact (40) and the insulation (92) of the wire (90).

Additionally, projecting parts (26) which contact the rear ends (18b) prevent more than a specified amount of deformation of the elastic contact members (18). The projecting parts (26) are provided at a specified distance to the rear of the positions of the rear ends (18b) of the elastic contact members (18).
