Abstract: A length of that portion of each of connection terminals 19 which projects from a partition wall 11a into a sealing member chamber 21, and includes an electrical contact portion 19a is larger than a length of an outer peripheral wall 11d of a connector portion 18, extending from the partition wall 11a in surrounding relation to the electrical contact portions 19a of the connection terminals 19 to form the sealing member chamber 21, so that at least distal end portions of the electrical contact portions 19a of the connection terminals 19 project outwardly from the connector portion 18 in a direction of fitting of the connector portion 18 to a mating connector 33.

Abstract: A waterproof structure between a cable and a housing is structured not spoiling a waterproof performance even if a cable is bent drawing a rapid curve. The waterproof structure between the cable and the housing comprises the cable led from the housing, a waterproof member closely attached to the housing and the cable, and a peel-prevention member for preventing peeling of the waterproof member with respect to the cable being bent, and is characterized in that the peel-prevention member is mounted on the cable and wrapped internally by the waterproof member. The waterproof member is formed with a hot melt material, and the peel-prevention member is formed with a material having excellent adhesion to the hot melt material. A shrinkage tube is served as the peel-prevention member.

Abstract: An electrical connector has a housing accommodating a plus signal terminal and a minus signal terminal. The connector housing also accommodates a first ground terminal corresponding to the plus signal terminal and a second ground terminal corresponding to the minus signal terminal. Each of the plus signal terminal, the minus signal terminal, the first ground terminal, and the second ground terminal is positioned at each corner of a quadrangle. A distance between the plus signal terminal and the first ground terminal is shorter than a distance between the minus signal terminal and the first ground terminal, while a distance between the minus signal terminal and the second ground terminal is shorter than a distance between the plus signal terminal and the second ground terminal. The connector may have a retainer body received in the connector housing for retaining the plus signal terminal, the minus signal terminal, the first ground terminal, and the second ground terminal.
