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 enhance operability when removed. SOLUTION: In state that both housings 10, 20 are coupled and a portion 41b of sealing member 41 is fitted between a terminal receiving member 21 and a fit pressure member 31, a cavity (a space for receiving terminals) provided between both housings 10, 20 is tightly sealed. When both housings 10, 20 are separated from each other, the fit pressure member 31 is shifted to a position for releasing fit pressure to release a fit pressure of the pressure member 31. Accordingly, the cavity 22 is communicated to atmosphere at fit pressure released portion, and negative pressure is not generated in the cavity to thereby reduce separating resistance.

摘要： PROBLEM TO BE SOLVED: To provide a connector suited for assembly using an automechanism and capable of avoiding an increase in number of part items. SOLUTION: A printed circuit board 20 (conducting path) is assembled into a storage space 14 while passing through an assembly opening 15 in a direction crossing the direction for fitting with a mating connector. In a fitted state, wall parts 12L, 12S and locking parts 13 correspond to the four outer peripheral sides of the mating connector, thus regulating loosening of the mating connector. Since the fitting portion 11 can remain a single component, the number of part items and a man-hour for assembly do not need to be increased. When assembly is made using an automechanism, the printed circuit board 20 can be assembled as by dropping it from above, so that the automechanism does not need to be provided with means for detecting the horizontal position of the printed circuit board 20 during assembly processes.

摘要： PROBLEM TO BE SOLVED: To surely detect half insertion of a terminal metal fitting. SOLUTION: In an assembling process of a bus bar body 50 in a housing 10, a temporary lock position lying short of a normal assembling position for short-circuiting a terminal metal fitting 20 is set on the deeper side in the assembling direction than a position where the bus bar body 50 hits against a lance 12, and a tab piece 57 makes no contact with the terminal metal fitting 20 from the start of the assembling of the bus bar body 50 till its arrival at the temporary lock position. Because the bus bar body 50 does not undergo contact resistance between the tab piece 57 and the terminal 20 from the start of the assembling, via the position where it hits against the lance 12, till its arrival at the temporary lock position, assembling resistance owing to the hitting against the lance 12 is discriminated from assembling resistance owing to the contact of the terminal metal fitting 20 with the tab piece 57, and thus the inserted state of the terminals metal fitting 20 can be surely detected.

摘要： PROBLEM TO BE SOLVED: To enable a retainer incorrectly reaching a secure locking position to be returned to a temporary locking position by simple operation prior to inserting a terminal bracket into a connector housing. SOLUTION: A retainer return pore is opened on a top face of a connector housing 1 so that when the retainer reaches a secure locking position a tip end of a temporary locking protrusion 13 is protruded from this pore. When a female terminal bracket is inserted into a connector, pressing against the connector is made by means of a press jig 20 prior to this insertion, however, if the retainer is mistakenly moved to the secure locking position, a pressure face 20A formed at the jig 20 pushes a protrusion end of the temporary locking protrusion using this pushing movement. As a result, the whole retainer is forcibly pushed back to the temporary locking position.

摘要： PROBLEM TO BE SOLVED: To aim at improvement of mounting workability for a panel. SOLUTION: If a lock member 28 is to be intervened between a panel P and a receiving part 19, since the first connector 10 is displaced in the same direction as a penetration direction of a mounting hole H and a sealing member 20 is pinched and pressed between a pressing part 13, a sealing is achieved between the panel P and the first connector 10. By the fact that the lock member 28 is installed between the panel P and the receiving part 19, the first connector 10 is regulated of slipping off from the panel P, and locked to a mounting state. Since there is no necessity to rotate the first connector 10 at the time of mounting on the panel P, friction resistance does not occur between the sealing member 20 and the panel P or between the sealing member 20 and the pressing part 13.

摘要： PROBLEM TO BE SOLVED: To reduce a number of parts. SOLUTION: At a terminal fittings 40, an elastic contact piece 50 (the first connecting part) facing at an inside of housing 10 in a mounted state to the housing 10, and a lower part connecting part 42 (the second connecting part) contacted to the elastic contact piece 50 of the terminal fittings 40 mounted on the housing 10 to enter the inside of housing 10 to become a coupling pair in a mutually coupled state of housings 10. As the plural mutual housings 10 have been directly coupled, other coupling members to couple the mutual housing 10 is unnecessary.

摘要： PROBLEM TO BE SOLVED: To prevent a tear mark from being produced on each tab piece when a bus bar body is separated from a carrier. SOLUTION: A bus bar body 50 is assembled in a housing and tab pieces 57 are brought into contact with terminal metal fittings, thereby short-circuiting the terminals metal fittings. In manufacturing the bus bar body 50, first, a plurality of bus bars 55 are linked to an edge part of a carrier 71 by means of bridge parts 72, a chain terminals 70 is press-molded having a shape connected to the bridge parts 72 at edge parts of link parts 56 of the bus bars 55, the bus bars 55 are unified with a holding body 51 by insert-molding, and this is separated from the carrier 71 by tearing up the bridge parts 72. In the form of the chain terminal, the bus bars 55 are locked not to tab pieces 57 but to the carrier 71 at the edge parts of the link parts 56, and therefore no tear mark is produced on the tab pieces when the bridge parts 72 are torn up.
