摘要： PROBLEM TO BE SOLVED: To provide a connector with a small-sized housing capable of passing through a smaller through hole. SOLUTION: A thickness dimension of the whole of a lower wall 33 can be made smaller than that in a conventional connector to pass the housing 31 through the smaller through hole 19 by making a region in front of lance 37 as open parts 38 of the lower wall 33 of the housing 31. A rib 39 is projectingly provided between the open parts 38 corresponding to adjacent cavities 32A and 32A, and thereby a creeping distance between the cavities 32A and 32A becomes larger, and when water is splashed on the connector 30, generation of leak current between both of the cavities 32A is prevented. The rib 39 projects at only at intermediate position of the adjacent cavities 32A and 32A, and thereby the rib 39 is difficult to interfere with a hole edge part of the through hole 19 and upsizing of the through hole 19 can be avoided.

摘要： PROBLEM TO BE SOLVED: To prevent the retainer from being pushed into the admission position anadvertently. SOLUTION: The retainer 20 is formed in one body through a hinge 30 that is capable of expansion and contraction, and a protrusion 28 is formed at the top end of the retainer 20. When the hinge 30 is in expanded state, if a rotating force is added to the retainer 20 in the direction of closing, the protrusion 28 touches the front edge 21A of the retainer mounting recess 21 before it arrives the admission position, and a further rotation is restrained, that is, an inadvertent locking into the admission position does not happen. When a female side terminal fitting 15 is inserted in the cavity 12, the retainer 20 is made to rotate in the direction of closing centering on the hinge 30, and, if the retainer 20 is pushed to the rear obliquely at close to the finishing of rotation, the retainer 20 moves to the rear side, while the hinge 30 contracts in loop shape. And if the retainer 20 is further rotated, the retainer 20 is rotated to the admission position as the protrusion 28 enters inside the front edge 21A of the retainer mounting recess 21.

摘要： PROBLEM TO BE SOLVED: To improve an inserting workability of a wire and a terminal fitting to an insertion hole. SOLUTION: The rubber stopper 40 fitted to the back surface side of a housing 20 is provided with an insertion-through hole 42 passing through back and forth, capable of letting in a female terminal fitting 13 and a wire 10, and three back and forth inner periphery lips 43 are provided swollen inward. The inner periphery lip 43 is equipped with an adhesion lip 44 at the center, and also a pair of insertion resistance reducing lips 45 in front and at back having a larger inside diameter than that of the adhesive lip 44. When the female terminal fitting 13 and the wire 10 are inserted through the insertion-through hole 42, frictional resistance is produced, because each inner periphery lip 43 is made to slide and contact the outer periphery of the female terminal fitting 13 and the wire 10 compressed by the female terminal fitting 13 and the wire 10. This frictional resistance is reduced at the insertion resistance reducing lips 45 as compared with that at the adhesion lip 44.

摘要： PROBLEM TO BE SOLVED: To reduce the size of a water-proof connector provided with a water- proofing function for an individual chamber. SOLUTION: Plural storage protrusions 16 inserted with male side terminal metals 18 are separately projected arrayedly in a deep face of a hood part 12 of a male housing 10, and a seal member 30 provided with cap parts 31 for covering the respective protrusions 16 individually is fitted. A press-in groove grid 35 is formed between the adjacent cap parts 31 and an inner circumferential face of the hood part 12, and a rib grid 44 pressed into the press-in groove 35 is upright in a front face 42 of a female housing 20. Lip parts 37A, 37B of which the each is laid around an outer circumferential face of the each cap pat 31 are provided, and formed positions thereof are shifted to a front position and a rear position in the respective caps 31 adjacent vertically and laterally, to be arranged zig-zag. An interpole pitch is narrowed to reduce the size of the connector, and peak positions of insertion force are shifted to realize small force insertion.

摘要： PROBLEM TO BE SOLVED: To smoothly perform attachment work to a panel P. SOLUTION: A clearance hole 14 is incised in an opening rim of an attachment hole 1 of the panel P, and a bayonet piece 13 protrudes from a contact housing 2 according to the clearance hole 14. Attachment of the contact housing 2 is performed, by adapting the bayonet piece 13 to the clearance hole 14 for fitting it in and making it rotated. A rubber ring 3 slidably contacts with a panel P face. It will not abut by its face to the panel P face throughout a wide area but reduces a contact area by providing an easily and flexibly deformable seal lip 15. As a result of this, sliding resistance is reduced during rotational operation, in comparison to conventional ones to smoothen and facilitate work.

摘要： PROBLEM TO BE SOLVED: To avoid decrease in the strength of wall parts is caused by a cutting and standing up of the wall parts in a metal fitting of a female terminal, where deflection regulation parts for regulating an excessive deflection of an elastic contact strip are formed by cutting and standing up the wall parts of an engagement area. SOLUTION: Front and rear sides deflection regulating parts 26F and 26R for regulating an excessive deflection of an elastic contact strip 20 are formed, by cutting and standing up an engagement part 11. The front-side deflection regulation part 26F is formed on a bottom wall 13 of the engagement part, while the rear-side deflection regulation part 26R is formed on a sidewall 14 thereof. Since the two deflection regulating parts 26F and 26R are formed on different wall parts, a smaller area for opening for cutting and erecting each wall part, when compared with, the two being formed on the same wall part, the strength of the wall parts can be maintained.

摘要： PROBLEM TO BE SOLVED: To form a wide lance so as to improve a lance holding force. SOLUTION: A connector housing H is constituted in such a way that a terminal receiving part 20 in which a cavity 21 is formed is mounted in a main body 10 on which a lance 15 is formed. In an inside of the cavity 21, a female terminal fitting 30 is housed and locked by the lance 15. The lance 15 is formed by utilizing a space in which a side wall 22 of the cavity 21 is mounted. Thereby, a wide lance 15 is provided along total widths of the cavity 21. Accordingly, a terminal holding force of the lance 15 is improved.

摘要： PURPOSE: To eliminate damage to terminal metal fittings. CONSTITUTION: A maintenance hole 23 is formed on a corner part on the opposite side to the housing position of terminal metal fittings, with a semi-insertion detection piece 22 between, on the ceiling surface inner peripheral side of a cap type retainer 20. Consequently, even when a jig is inserted, it does not reach terminal metal fittings, and damage can be eliminated.

摘要： PURPOSE: To detect incomplete insertion of a terminal metal fitting by adjusting the depth of a recess, by inserting a probe by forming the recess on the front end of a surface on which a resin lance is not formed. CONSTITUTION: When a resin lance 22 is provided in a cavity 21, a recess 21b having a prescribed depth into which a probe 50 can be inserted, is formed in an opening side end part of a surface on which this resin lance 22 is not formed. Therefore, when a female side terminal metal fitting 60 is not inserted up to a normal position, since the probe 50 cannot be inserted only up to the inner part of the recess 21b, it cannot electrically continue with the female side terminal metal fitting 60, so that incomplete insertion can be detected.

摘要： PURPOSE: To increase holding force and also to provide durability. CONSTITUTION: In a cap-shaped retainer 20 comprising a front/side surface wall 21, 22, a pair of parallel slits 23, 23 of closing both ends are formed in the side surface wall 22 serving as a peripheral wall, and an arm piece 24 with both ends held is formed between the slits. By holding the both ends of the arm piece 24, a lock protrusion 25 formed in an internal peripheral surface side is strongly pressed to a cavity part 11 serving as a secured object, to provide durability by eliminating a free end while improving holding force.
