摘要:
A mating contact portion is formed by folding a plate member into a tongue-like configuration matable with a metallic female terminal, including a contact part in which the plate member is folded in a longitudinal direction along a bending part disposed at a tip of the mating contact portion.

A connector in which the longitudinal displacement of connection terminals is positively prevented even if electric wires are pulled rearwardly by an external force, so that the fitting property of the connector to a partner connector can be improved. In the connector according to the present invention, a plurality of solderless terminals (1) are chained to a carrier having feed holes (11), with each of the terminals having an electric-wire solderless contact portion (5) provided with a slot (4) for solderlessly connecting an electric wire. The terminals are severed from the carrier in such a manner that portions of feed holes (11) of the carrier remain in the rear end portions of the solderless terminals (1). Additionally, fitting portions (14) to be fitted into the feed holes (11) are formed on the bottom walls of a terminal holder (2) in which the terminals are received. Since the feed holes (11) are provided in the rear end portions of the solderless terminals (1), the strength of the solderless terminals (1) is not reduced. Furthermore, since the fitting portions (14) are provided so as to project from the bottom walls (12) of the terminal holder (2), the strength of the bottom walls (12) is likewise not reduced.
摘要:
A nitrogen-containing molecular sieving carbon which contains at least 0.1 weight % nitrogen bonded to constituent carbon of the activated carbon. It exhibits improved ability to remove nitrogen oxides compared with the conventional adsorption methods using commercially available activated carbons or other absorbents. Also an economically advantageous system for removing nitrogen oxides is provided which needs no reducing agent such as ammonia, no oxidizing agent such as ozone, or no electrical and physical energy such as electron rays or ultraviolet light in its operation, needs no expensive catalysts, and can be semipermanently operated with regular changes of the relatively low-priced activated carbon.

To improve the insertion workability of a terminal part (29) into a connector housing (25), a reverse insertion preventing connector comprises: a terminal part (29) and a connector housing (25). The connector housing (25) is formed with a flexible engage arm (31) having an arm portion (37) extending from an inner wall (33) thereof, an engage step portion (43) engaged with the terminal part (29) when the terminal part has been inserted into the connector housing (25) in a normal direction, and an arm end projection portion (47) engaged with the terminal part (29) when the terminal part is being inserted into the connector housing (25) in a reverse direction. In particular, the connector housing (25) is further formed with at least one terminal insertion guide slope portion (51) extending from the inner wall (33) thereof to such a position as to be roughly flush with the arm end projection portion (47) beside the flexible engage arm (31) so as to guide the terminal part (29) as it is inserted into the connector housing (25).
摘要:
A connector including a separate terminal retainer for retaining terminals in a connector housing where the retainer can be disengaged from the connector housing without the use of external jigs. The connector includes the connector housing having a plurality of terminal accommodating chambers, and the terminal retainer adapted to be connected to a rear portion of the connector housing in a two-step manner, i.e. a provisional engagement condition and a complete engagement condition, and movable relative to the connector housing. The terminal retainer has flexible retaining pieces and flexible support pieces. In the complete engagement condition, the flexible retaining pieces are engaged with respective metal terminals by their own flexibility, and the flexible support pieces are guided and elastically bent by the drive surfaces of the connector housing to be engaged with respective metal terminals. When the terminal retainer is moved backward from the complete engagement condition beyond the provisional engagement condition, the flexible retaining pieces ride onto projections of the connector housing to be displaced out of the locus of movement of the metal terminals being removed. The metal terminal can be easily removed from the connector housing without using any jigs.
摘要:
A process for direct zinc electroplating of aluminum strip which can be performed continuously at a high speed and a high current density. The process comprises pretreating aluminum strip by alkaline degreasing and then pickling and subjecting the pretreated aluminum strip to zinc electroplating in an acidic zinc plating bath which contains, in addition to Zn.sup.2+ ions, metal ions selected from the group consisting of Ni.sup.2+ ions and Fe.sup.2+ ions in a concentration of at least about 10 g/1 to form a Zn-Ni, Zn-Fe, or Zn-Ni-Fe alloy plated coating, which may be overlaid with another zinc electroplated coating.
摘要:
A connector housing and a lid are formed integrally of synthetic resin, the lid being connected in hinged fashion to the connector such that the lid travels in a substantially constant orbit so that engagement portions thereof lock with corresponding lock levers on the connector housing. The overall construction facilitates closing and opening with one-hand operation.
摘要:
The electrical connector according to the present invention is capable of doubly latching a terminal inside the terminal accommodation chamber of the insulated housing, with a locking device (locking plate) additionally provided to further secure the double latched state. This arrangement checks for any improperly inserted terminals while reinforcing the hold on the terminal in place. In addition, the reliability of the electrical connection by the connector is further boosted by the device embodying the present invention.
