Abstract: Housing-side intimate contact ribs are formed on a rear end surface of a male connector housing, and a holder-side intimate-contact ribs are formed on a mat seal holder which holds a mat seal on the male connector housing. These intimate-contact ribs are inserted respectively in inlet portions of intimate-contact cavity portions formed in the mat seal, thereby provisionally retaining the mat seal. In this condition, metal terminals can be easily and positively passed respectively through wire insertion holes in the mat seal.

Abstract: The locking structure includes a locking part configured to lock with mating members defining locking holes. The locking part includes at least two insertion parts. The insertion parts include pairs of guide walls defining insertion channels extending in respective directions for inserting and supporting mating members. The insertion parts include locking protrusions between guide walls for engaging with the locking holes of the mating members.

Abstract: Connector assembly (2, 3) includes internal and external connector housings (7, 15) matable with each other. The assembly includes a cam projection (3A) provided to one of the internal and external connector housings. The assembly includes a lever (8) provided rotatably to another one of the internal and external connector housings. The lever defines a cam channel (13) for guiding the cam projection therein to mate the internal and external connector housings with each other. The assembly includes a false-assembly preventing structure (3Ba, 3Bb S1, S2) operative to prevent false-assembly of the internal and external connector housings at an initial mating. The lever is rotatable to push the cam projection to space the internal and external connector housings off.

Abstract: An electrical connector assembly consists of a first connector having a driven member rotatably supported thereon and a resilient member provided between the first connector and the driven member; and a second connector having a drive means which engages with and drives the driven member into rotation to bias the resilient member, wherein the resilient member, when biased, produces a repulsion force and a drawing force in order, the repulsion force and the drawing force acting through the driven member on the second connector in directions of repelling and drawing the second connector, respectively. A reliable coupling with a low force and an improved working efficiency are attained.

Abstract: A housing 3 of a female connector 1 has a receiving space 5 for a slide lock member 15 and a resilient member 17, and this receiving space 5 is provided near to a terminal receiving chamber 7 for receiving a connection terminal.

Abstract: In the metal piece 32 which diffuses into the fuse element so that an alloy layer is generated, there is formed an expanding slot 30, which is inserted and pressured in the fusing portion 25b of the fusible body 25 which forms the fuse element. Due to the foregoing, the metallic mass 32 of low fusing point is fixed to the fusible body 25 while it surrounds the circumferential surface of the fusing portion 25b.
