  • Publication number: 20130072061
    Abstract: A terminal fitting (40) has a waterproof member (50) is mounted to cover a contact part between a wire barrel (42A) and a core (31) of a wire (30) from the wire barrel (42A) to an insulation barrel (42B). A peripheral wall (17) of the cavity (11) is formed with a locking lance (19) that is resiliently deformable in a width direction of the cavity (11) and retains the terminal fitting (40) by being engaged with the terminal fitting (40). A recess (22) for widening the width of the cavity (11) is formed in a part of the peripheral wall (17) formed with the locking lance (19) corresponding to the insulation barrel (42B). The barrel portion (42) of the terminal fitting (40) is bent that the insulation barrel (42B) projects toward the recess (22).

  • Publication number: 20130008714
    Abstract: An aluminum electric wire (10) has a metallic core wire (11) coated with an insulation coating (13). A female terminal fitting (20) made of metal different from the core wire (11) has a wire barrel (25) to be connected to the aluminum electric wire (10). A solder seal (30) is formed of solder having a main component with an ionizing tendency close to that of the terminal fitting. The wire barrel (25) is crimped to the core wire (11) exposed by peeling off the insulation coating (13) of the aluminum electric wire (10) and partially sealed with the solder. A seal connection portion (14) connects the insulation coating (13), the exposed core wire (11) and the solder seal (30) to each other in a condition where the coating (13) and the solder seal (30) are sealed off from each other.

  • Patent number: 7347744
    Abstract: Each of a plurality of auxiliary connector (10) includes an auxiliary housing (11), a seal (40) attached to the rear of the auxiliary housing (11), and a rear holder (50) mounted on the rear of the seal (40) to retain the seal (40). Auxiliary connectors (10) that are adjacent in an arranging direction are united by the rear holders (50). The united auxiliary connectors (10) are inserted into a frame (60) in the arranging direction through an insertion opening (60A) of the frame (60), and are retained in the frame (60) by engaging a lock (50B) on the last auxiliary connector (10A) and an interlocking portion (61) of the frame (60). The frame (60) has no partition walls between the auxiliary connectors (10). Thus, the connector is narrowed by a total thickness of the partition walls.

  • Patent number: 7145752
    Abstract: A magnetic head apparatus including a magnetic head slider having an overall front half region area (S) and a step surface area (S1) and a positive-pressure generating surface area (S2) both in the front half region, such that the area ratio S1/S is about 0.180 to about 0.232 and the area ratio S1/S2 is about 0.30 to about 0.47. With this arrangement a difference in pitch angles of the magnetic head slider at the moment when it is just levitated and during levitation is large, and a variation of the pitch angle due to a pressure change is small, thereby preventing damage to a magnetic element within the magnetic head slider while achieving a stable levitation attitude of the magnetic head slider.
