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.

An agitation method for mixing a solution and a solvent to precipitate a solid substance from the solution. The method includes preparing an agitation mixer including an agitation vessel, an impeller rotated in the agitation vessel, and a feed pipe connected to the agitation vessel and having a multiple pipe structure including an outer pipe and an inner pipe arranged in the outer pipe. A shearing clearance is formed in the agitation vessel between the impeller and the feed pipe. The method further includes shearing the solution and the solvent by rotating the impeller to precipitate the solid substance while feeding the solution and the solvent into the shearing clearance from the outer pipe and the inner pipe.

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.

An electronic unit includes a case, a printed circuit board, a connector block, and a connector introducing portion. The case is selected from a waterproof case and a non-waterproof case. The connector block is mounted upon the printed circuit board. The connector block has a retaining projection that engages a mating connector. The connector introducing portion is integrally formed with the cases and yet separately from the connector block. The connector introducing portion of the waterproof case has a retaining projection that engages the mating connector. The electronic unit is assembled with the case selected from the waterproof case and the non-waterproof case, and with the printed circuit board and the connector blocks received in the case that has been chosen.

A coaxial cable shielding terminal includes a cylindrical inner terminal accommodating portion, an insertion portion and a press-clamping portion. The cylindrical inner terminal accommodating portion accommodates an inner terminal connected to a conductor core. The insertion portion extends from an end of the inner terminal accommodating portion, and is inserted into between a braided shield and an insulating cladding at an exposed area of the braided shield. The press-clamping portion is provided separately from the insertion portion, and press-clamps the exposed area of the braided shield so that the braided shield is sandwiched by the insertion portion and the press-clamping portion. A concave portion or a convex portion is provided on at least one of an outer surface of the insertion portion and an inner surface of the press-clamping portion to sandwich the braided shield.

A connector includes a first and a second terminal portions each having: a substrate pressing portion; a spacer pressing portion; and a fulcrum portion arranged between the substrate pressing portion and the spacer pressing portion, a spacer arranged between the spacer pressing portions of the first and the second terminal portions, and a clipping section formed of the substrate pressing portions of the first and the second terminal portions. The clipping section opens and closes while operating the fulcrum portions as a fulcrum. The spacer pressing portions of the first and the second terminal portions close via the fulcrum when the clipping section opens.

The present invention is to provide a waterproof connector having an adjusted spacing between terminals or electrical wires for achieving an effective waterproof. The electrical wires received in a terminal receiving portion of an outer housing are guided to a wire seal fit portion, while the electrical wires are pressed with wire holders (displacement limit portions). The electrical wires are then passed through a holder (spacing adjusting portion), a seal member, and another holder (lead-out portion) of a wire seal in the wire seal fit portion. The wire seal is fitted into the wire seal fit portion for achieving waterproof of the waterproof connector. The electrical wires guided out of the lead-out portion have an equal spacing therebetween by expansion of the spacings between the electrical wires or displacements thereof. The equal spacing ensures insertion of the seal member and provides the effective waterproof.
