  • Patent number: 7695290
    Abstract: A board connector (1) has a housing (10) and terminal fittings (20) penetrate through the back wall (11) of the housing (10). A board connecting portion (21) of each terminal fitting (20) penetrates through the back wall (11) and is solder-connected to a board (2). The housing (10) has a heat transfer inhibiting portion for inhibiting heat transfer to the back wall (11). The heat transfer inhibiting portion has a through-hole (13) or heat-insulating grooves (17) in the back wall (11). As a result, heat transfer to the back wall (11) is inhibited and deformation of the back wall (11) due to thermal expansion also is inhibited. Consequently, it is possible to prevent the terminal fittings (20) from separating from the board (2) and going into a state of being not solder-connected thereto.

  • Patent number: 7467956
    Abstract: A plurality of terminal fittings 11 are mounted to a housing 20, board connecting portions 13 having mounting portions 14 at lower ends protrude rearward, fixed fittings 30 having mounting plates 32 at lower edges are mounted to opposite side surfaces of the housing 20, and the mounting portion 14 of each terminal fitting 11 and the mounting plates 32 of the fixed fittings 30 are secured to a PCB 40 by reflow soldering. During the reflow soldering, a drawing force toward the PCB 40 acts on each of the terminal fittings 11 and the fixed fittings 30 based on surface tension of molten solder H, but the center of the fixed fitting 30 in the fore/aft direction of the board connecting portion 13 is positioned forward of the center of gravity position O of a connector 10, and rotation moment Mb toward the PCB 40 acts on the front of the housing 20 based on a drawing force Fb on the side of the fixed fitting 30 to prevent the front from being raised.

  • Patent number: 7303445
    Abstract: A male connector (M) is provided with a receptacle (10) and a female connector (F) is provided with a housing (40) that can fit into the receptacle (10) from the front. Mounting grooves (18) are formed by recessing both side walls (16) of the receptacle (10) and fixing members (30) are mounted into the mounting grooves (18). The fixing members (30) are fixed to a circuit board (80) by soldering. Engaging projections (49) bulge out sideways from the opposite side surfaces of the housing (40). Engaging grooves (19) are recessed in the inner side surfaces of the both side walls (16) of the receptacle (10) at positions before the mounting grooves (18) and engage with the engaging projections (49) as the connectors (F, M) are connected to resist a tensile force acting when the housing (40) is pulled away from the circuit board (80).

  • Patent number: 7033205
    Abstract: Collision preventing projections (50) are provided on an outer surface of a female housing (20) and will contact an opening of a receptacle (11) of a male housing (10) if a main portion (21) of the female housing (20) is inserted into a receptacle (11) in an oblique posture. Thus, the collision preventing projections (50) ensure that the main portion (21) and male terminals (12) are spaced apart when the main portion (21) is pushed into the receptacle (11) in this oblique posture.

  • Patent number: 6786751
    Abstract: A combined terminal fitting assembly is provided to fix ends of three or more wires to one fixing place. Engaging portions (25, 26, 34, 35) for holding a right terminal fitting (TR) and a left terminal fitting (TL) assembled are provided on both upper and lower surfaces of terminal main bodies. Thus, the right terminal fittings (TR) and the left terminal fittings (TL) can be placed alternately one over another. As a result three or more wires (W) can be fixed to one fixing place. Upon assembling, the wire (W) of the right terminal fitting (TR) and the wire (W) of the left terminal fitting (TL) are brought gradually closer to each other from most distant positions. Thus, the left and right wires (W) neither overlap nor interfere with each other.

  • Patent number: 6767259
    Abstract: A terminal fitting (1) has connecting portion (5) with an engaging portion (14) to be engaged with a resin lock (13) of a connector (3). The engaging portion (14) projects with a step from an upper wall (12) to ensure a large engaging area with the resin lock (13). An outer edge (14A) of the engaging portion (14) is closer to the resin lock (13) than an inner edge (14B) thereof. Thus, when the terminal fitting (1) is pulled back in withdrawing direction, a force acts to move the leading end of the resin lock (13) from the outer edge (14A) of the engaging portion (14) toward the inner edge (14B). Therefore, the terminal fitting (1) is difficult to disengage from the resin lock (13), and a large engaging force is secured.

  • Patent number: 6439921
    Abstract: In a terminal of an FFC (10), upper and lower surfaces of a conductive path (11) are covered with an insulation sheet (12). A terminal fitting (20) for the FFC (10) includes a base plate (22) extended from the rear end of a terminal fitting (20). Contact blades (25) are erected on both side edges of the base plate (22). A pressing plate (23) that can be opened and closed confronts the base plate (22). The contact blades (25) pierce through the rear surface of the conductive path (11) of the FFC (10) and project from the upper surface thereof. The pressing plate (23) then is closed in sliding contact with the contact blades (25) at both side edges of the base plate (22) to press the FFC 10 against the base plate (22). Upper end portions of the contact blades (25) then are crimped to the side edge of the pressing plate (23). Because the FFC (10) is pressed against the base plate (22), the conductive path (11) interposed between the contact blades (25) is straight, horizontal and compressed vertically.

  • Patent number: 6416348
    Abstract: An insulation-displacement terminal fitting (10) has plate-shaped blades (27) disposed before V-shaped contact portions (23) along a wire-insertion direction. The blades (27) make cuts (C) in an insulation coating (Wb) of a wire (W). The insulation coating (Wb) then is cut open by the V-shaped contact portions (23). A cut-open piece (Wc) of the insulation coating (Wb) that is caught by the contact portions (23) is not forcibly stretched. Thus, a core (Wa) is not pulled in a direction to be withdrawn from a clearance between the contact portions (23). An accommodation space (30) in which the caught cut-open piece (Wc) of the insulation coating (Wb) is accommodated is located within a height range of side walls (21). Thus, the cut-open piece (Wc) of the insulation coating (Wb) does not project above the side walls (21).

  • Patent number: 6413115
    Abstract: A connector has opposed side walls (12) with a wire-receiving space therebetween. Insulation displacement portions (17) are cantilevered from the side walls (12) by cutting portions of the side walls (12) and bending the cut portions into the wire-receiving space. Bent portions (17A) are formed by bending free ends (17B) of the insulation-displacement portions (17) back toward the respective side wall (12).

  • Patent number: 6386900
    Abstract: An insulation-displacement terminal has opposed side walls (12) and a wire-receiving space therebetween. V-shaped insulation-displacement portions (16) are formed by a pair of plates (16F, 16R) that are bent from the side walls (12) and project into the wire-receiving space. A bending angle (&bgr;) between one plate (16R) and the side wall (12) is larger than a bending angle (&agr;) between the other plate (16F) and the side wall (12). A pulling force on the wire (W) does not make a loose movement since the bending angle of the plate (16F) located at the side behind with respect to a pulling direction is a right angle. Further, since the bending angle (&bgr;) between the plate (16R) and the side wall 12 is larger, an angle (&ggr;) between the plates (16F) and (16R) of the insulation-displacement portion (16) is sufficiently large to ensure a wide contact area with a core (Wb) of the wire (W). Thus, a high contact reliability can be secured.
