A connector is provided that can easily insert a connecting terminal into a terminal accommodating hole of a housing and assuredly connect the connecting terminal to a connecting terminal of a mate side.Under a state that a connecting terminal 2 is held in a terminal accommodating hole 30 of a housing 3, when a slider 33 is slid to the terminal accommodating hole 30 side, a circumferential engaging part 35 abuts on an abutting surface 22a to rotate the connecting terminal 2 in the circumferential direction. Thus, the abutting surface 22a is held so as to be parallel to a slide direction of the slider 33.

2N (where N=1, 2, 3, . . . ) rod-shaped terminals, having overall lengths that vary in sequence, are formed out of a single metal plate by press punching. In the metal plate, rod bodies bridging between a first carrier and a second carrier are arranged so that the lengthwise direction of the rod bodies is perpendicular to the lengthwise direction of the metal plate, the 2N terminals are divided such that the first N in descending order of length are in a first group, and the remaining N are in a second group, the n-th shortest terminal and the n-th longest terminal are selected from the terminals of the first and second groups and combined one by one, and each combined pair of terminals is disposed in series over one rod body.

To provide a seal member for a waterproof connector which will not be deteriorated in waterproof performance even when wires swing, and is suited for use even in the type of connector in which an inner housing is swingable as in a floating connector, a seal member for a waterproof connector is mounted at rear ends of terminal receiving chambers of the waterproof connector, and has wire-sealing passage holes in which wires connected to respective terminals can be fitted, respectively. Lip portions are formed on an outer peripheral portion of the seal member over an entire periphery thereof, and also lip portions are formed on front and rear sides of the seal member spaced from each other in an inserting direction, and these lip portions can be compressed and deformed between the seal member and the terminal receiving chambers.

[Problems] To provide a packing which makes it easy to connect the connector housing to which the packing is attached to the mating connector housing, and keeps a connecting area between the connector housing watertight, and to provide a connector having the packing.[Means for Solving Problems] A connector 1 includes a male housing 17 and a packing 19. The male housing 17 is connected to a female connector housing. The packing 19 includes: a hard part 30 made of first elastic material, a center part thereof in a connecting direction K of the connector housings being in close contact with the connector housing 17 to form a V-shaped section; and a soft part 31 made of second elastic material softer than the first material, overlapped with the hard part 30 at the mating connector housing side, being in close contact with the mating connector housing.

A rubber stopper for a waterproof connector includes: a first elastic member including a first contact face, and first wire fitting grooves each having an arc cross-section; and a second elastic member including a second contact face and second wire fitting grooves each having an arc cross-section. When the first contact face contacts the second contact face, circular cross-section is formed by the arc cross-sections of the first and second wire fitting grooves to fit wires into the first and second wire fitting grooves. Arc length of the arc cross-section of the first wire fitting groove is different from arc length of the arc cross-section of the second wire fitting groove so that a center of the circular cross-section is disposed away from the first and second contact faces in a direction perpendicular to an extending direction of the first and the second contact faces.

A board-connecting connector including a pair of inner housings opposed to each other for receiving elastic contact terminals with respect to a circuit board, a guiding plate having a sloped guiding part for engaging inner housing-driven projections and guiding the inner housings close to each other, and an outer housing for receiving the inner housings and the guide plate, and holding the guide plate. When the circuit board is fully inserted into the pair of inner housings, the circuit board abuts on the inner housings, and pushes to move the inner housings along the guiding plate.
摘要:
The present invention provides a connector having a seal member for sealing around an electrical wire. The connector includes a connector housing, the seal member, and a rear holder. The connector housing has a layer-by-layer arrangement of plate-shaped housings which each have terminal receiving channels to receive terminals. The seal member has a seal main body surrounding the electrical wire and a tube portion projecting from the seal main body in the lengthwise direction of the electrical wire. The rear holder includes a plurality of holders to pinch the tube portion of the seal member. Each holder has a groove to pinch the tube portion of the seal member and the groove compresses an inner diameter of the tube portion when the holders pinch the tube portions therebetween.
