摘要:
An exhaust gas-purifying catalyst includes a support provided with one or more through-holes through which exhaust gas flows, and a catalytic layer supported by the support and containing an oxygen storage material. The exhaust gas-purifying catalyst includes a first section to which the exhaust gas is supplied, and a second section to which the exhaust gas having passed through the first section is supplied. The catalytic layer includes a layered structure of a first catalytic layer containing platinum and/or palladium and a second catalytic layer containing rhodium in the first catalytic section and further includes a third layer containing rhodium in the second section. The second section is smaller in oxygen storage material content per unit volumetric capacity than the first section.

摘要:
A shielded connector assembly has first and second housings (11, 31). The first housing (11) has a fitting space (17) formed with coupling ribs (16). A shielding shell (26) is in the fitting space (17) and has slits (27) that receive the coupling ribs (16). A preventing groove (29) is formed in a peripheral surface of a fitting space (17) and receives a projection (37) of the second housing (31) when the housings (11, 31) are connected properly. The preventing groove (29) is aligned with the slit (27) so that the slit (27) also receives the projection (37). Thus, it is unnecessary to form a separate notch to receive the projection (37).

A protective wall (42), formed in a unified manner, rises to a specified height from the posterior end of a base face (41) of a detecting chamber (40). A short-circuiting terminal (50) is inserted into the detecting chamber (40) from the anterior, a base member (51) thereof striking against the protective wall (42), thus fixing and maintaining the position of the base member (51). A retainer (60), retains the short-circuiting terminal (50) in a specified position and in an unremovable state. Foreign objects attempting to enter the detecting chamber (40) from the posterior will strike against the protective wall (42). The protective wall (42) via a sealing cover (43), also regulates the travel of the locking arm (30) and thus the terminal (50).
摘要:
To effect water-proofing using a non-water-proof type of female connector, a non-water-proof female connector (20) is fitted with a concave fitting member (12) of a male connector (10), a cover assembly (30) fitting with both the female connector (20) and the concave fitting member (12). The cover assembly (30) is provided with a ring-shaped seal (40) which fits tightly with the rim of the circumference of the fitting member (12), thereby sealing the portions of the two connectors (10) and (20) that fit together. A gel seal (45) is compressed between the cover assembly (30) and the rear face of the female connector (20), this preventing water from entering via terminal attachment holes (21) on the rear face of the female connector (20).
摘要:
A circuit board connector housing (10) includes slide contacts (19) arranged before contact areas (16) of detecting terminals (15A) with respect to a connecting direction. The slide contacts (19) contact touching portions (30) of shorting terminals (27) during a connecting operation of two housings (10, 20). The slide contacts (19) remove foreign matter from the touching portions (30) during the connecting operation of the two housings (10, 20). Thus, extra efforts to remove foreign matter are not needed before the housings (10, 20) are connected. The absence of foreign matter on the touching portions (30) achieves good quality contact with the contact areas (16) of the detecting terminals (15A) and assures reliability of a connection detecting function.
摘要:
A split-type connector (10) has a holder (11) and auxiliary connectors (28) that can be mounted in the holder (11). A retainer (34) is mountable in the holder (11) and can be moved from a first position where the auxiliary connectors (28) can be mounted in the holder (11) and a second position where the auxiliary connectors (28) are locked. The retainer (34) has returning slanted surfaces (40) for pushing the retainer (34) from the second position to the first position in the process of mounting auxiliary connectors (28) into the holder (11).
摘要:
A one-piece type waterproof rubber plug 30 is formed with round insertion holes 32 whose inner surfaces can be held in sealing contact with the outer surfaces of a plurality of wires 18 individually inserted into the insertion holes 32 to protect them from water. Female terminal fittings 14 having a box-shaped connection portion 15 are introduced into the insertion holes 32. In the inner surfaces of the insertion holes 32 are formed slits 50 in positions corresponding to corner portions 16 of the connection portions 15. While the female terminal fittings 14 are passing the insertion holes 32 by deforming them, the corner portions 16 enter the slits 50, thereby forcibly opening the slits 50 wider to form clearances 51. The corner portions 16 advance along the clearances 51. This prevents the corner portions 16 from damaging or scratching the inner surfaces of the insertion holes 32. After the passage of the female terminal fittings 14, the insertion holes 32 elastically narrow to close the clearances 51, with the result that the lips 33 are held in sealing contact with the outer surfaces of the wires 18. The insertion holes may include guides (140) for passage of terminal stabilizers (25). The guides (140) include closed sealing slits (150) to be forced open by passage of the stabilizers.
摘要:
In order to detect via an external circuit whether male and female connector housings 1 and 2 have been correctly fitted together, a short-circuiting terminal 19 which bends when a locking arm 10 bends either short circuits or fails to short circuit a pair of detecting terminals 7 located on the male housing 1. The area surrounding the short-circuiting terminal 19 is surrounded by an interior protecting wall which is covered by a flexible sealing cover 27. The sealing cover covers only the short-circuiting terminal and the locking arm remains exposed. The upper face of the interior protecting wall has an opening 25A. When the locking arm 19 is bent while the housings are being fitted, the short-circuiting terminal 19 is moved via the sealing cover 27 and the short-circuiting terminal and the detecting terminals 7 separate.
摘要:
A joint terminal which connects a plurality of electrically conductive spaced apart contacts. The contacts are electrically connected to each other by a connector at their proximal ends by means of a connector attached thereto. The portion of the joint terminal which protrudes from the housing is surrounded by an insulative resin layer. This provides both protection and gripping surfaces for insertion and removal of the joint terminal from the connector housing. Additionally, ridges are provided on the projecting portion which can be gripped by the fingers if needed.
