  • Publication number: 20160344151
    Abstract: A connector (C) in which pin-like terminal fittings (6) project from the back surface of a housing (1) is held in a setting tool (9) including an opening (13). The connector (C) then is conveyed to an operation position together with the setting tool (9). At the operation position, a suction device (16) is located to communicate with the opening (13) from below and a nozzle (21) is located above the opening (13). Cooled dry ice fine particles are blown toward the housing (1) and the terminal fittings (6) from the nozzle (21). Foreign matters with reduced adhering forces by being cooled come off from the adhering surfaces and are sucked and collected by the suction device (16).

  • Patent number: 7394018
    Abstract: Upper and lower casings (10, 11) are coupled together and are fixed to a holder (20) by a bolt (B). The upper casing (10) has an upper wall (10b) with a bolt hole (11c) and the lower casing (11) has a bottom wall (11b) with a bolt hole (11c). A cylindrical collar (15) is molded with the bottom wall (11b) of the lower casing (11) and projects from the edge of the bolt hole (11c). The collar (15) has a length to penetrate through the bolt hole (10c) in the upper wall (10b) of the upper casing (10). The collar (15) has a step (15a) for supporting a lower surface of a bolt head (Bb) of the bolt (B) and inward projection (15b) for engaging an upper surface of the bolt head (Bb). Thus, the bolt head (Bb) is held rotatably between the step (15a) and the inward projection (15b).

  • Patent number: 7367819
    Abstract: A terminal has a plurality of split solder portions inserted into through-holes in a printed circuit board. A first split solder portion has a cross-sectional shape such that four corners thereof contact an inner circumferential surface of the through hole for positioning, while a second split solder portion has a cross-sectional shape such that the portion is loosely inserted into the through hole without contacting an inner circumferential surface thereof. The plurality of split solder portions of the terminal are inserted into through holes having substantially equal diameters. The four corners of the first split solder portion contact the inner circumferential surface of the through hole for positioning and holding. The second split solder portion does not contact the inner circumferential surface of the through hole. The through holes are filled with solder to fix the split solder portions therein.

  • Patent number: 7056150
    Abstract: An electrical connector box constructed to prevent inaccurate insertion of a short circuit forming terminal to the contacts of an internal circuit. A shorting terminal includes a conductor plate having multiple tabs extending from a link portion, the link portion being covered by a cover, and a post that extends in the same direction as the tabs. A relay receptacle includes a post aperture into which post member of cover is inserted, thus allowing the tabs to enter specified terminal slots of the relay receptacle.

  • Patent number: 7044766
    Abstract: An automotive electrical connection box (10) has a casing main body (11) fastened to a holder (20) by a bolt (B). A mating connector (12) is mounted in the casing main body (11) and is connected with a waiting-side connector (21) in the holder (20) simultaneously with the fastening by the bolt (B). A dummy housing (13) projects from the casing main body (11) at a side of the bolt (B) opposite the mating connector (12), and an opening (22) is provided at a portion of the holder (20) corresponding to the dummy housing (13). The dummy housing (13) and the opening (22) engage and create a stress to balance a stress created upon connecting the waiting-side connector (21) and the mating connector (12).

  • Patent number: 6982379
    Abstract: An electrical connection box has upper and lower casings (10, 11) for accommodating circuitry. A surrounding wall (10a) of the upper casing (10) fits inside a surrounding wall (11a) of the lower casing (11). Engaging locking claws (10b, 11b) project from the outer surface of the surrounding wall (10a) of the upper casing (10) and from the inner surface of the surrounding wall (11a) of the lower casing (11). An upper wall of the upper casing (10) is inclined down from a center portion to three peripheral edges. A drainage path (13) is defined by a clearance between the surrounding walls (10a, 11a) of the upper and lower casings (10, 11). A bottom wall of the lower casing (11) has drainage holes (14) at the bottom end of the drainage path (13).

  • Publication number: 20050178575
    Abstract: Upper and lower casings (10, 11) have the surrounding walls coupled together. A bolt (B) is mounted beforehand in the casings (10, 11), and projects through a bolt hole (11c) in the lower casing (11) to fix the casings (10, 11) to a holder (20). A first bush (15) is fixed in the lower casing (11) and a second bush (16) is interlocked with an outer circumferential surface of the first bush (15). The bolt (B) passes through the bushes (15, 16) so that a lower surface of the bolt head (Ba) engages the upper end surface of the first bush (15). On the other hand, an inward-projection is formed on an upper part of the second bush (16), and contacts the upper surface of the bolt head (Ba). Thus, the bolt head (Ba) is held rotatably between the upper end surface of the first bush (15) and the inward-projection.

  • Patent number: 6899573
    Abstract: A coupling terminal unit (30) has terminal fittings (20) coupled in parallel by a coupling portion (31) and is stamped from a metallic plate so that the coupling portion (31) is extendible in an arranging direction of the terminal fittings (20). An arrangement pitch (A) of the terminal fittings (20) is narrower than an arrangement pitch of the terminal insertion holes (14). Then, since the coupled terminal unit (30) is stamped out such that the arrangement pitch (A) of the terminal fittings (20) is narrower than that of the terminal insertion holes (14), unnecessary portions between the terminal fittings (20) can be reduced. Thus, the utilization efficiency of a material for the production of the coupled terminal unit (30) can be improved.

  • Patent number: 6786754
    Abstract: A connector has a housing (20) with a lock arm (28) that engages a lock (13) of a mating housing (10) when the housings (10, 20) are connected properly. Resilient members (50) are movable along a connecting direction (CD) of the housings (20, 10) and are displaceable along a direction (RDD) intersecting the connecting direction (CD). The resilient members (50) are pushed back by the mating housing (10) as the housings (20, 10) are connected. A spring (70) between the resilient member (50) and the housing (20) accumulates a biasing force to separate the housings (20, 10) as the resilient member (50) is moved back. An operable member (40) is movable along the connecting direction (CD) and has an operating portion (80) displaceable to an operable position where the lock arm (28) can be operated to cancel the locked state.

  • Patent number: 6722913
    Abstract: A male housing (10) pushes the front ends of springs (50), and a pushing portion (13) at the front end of the male housing (10) is more backward than the front ends of the springs (50), and front end portions of the springs (50) and a front end of the male housing (10) overlap. Thus, a connector can be made smaller by an overlapping length of the springs (50) and the male housing (10).
