摘要:
A waterproofed connector has an outlet for an electrical cable which is molded by a resin material under a structure which can prevent a mold resin material from entering into terminal metal fixtures. The waterproofed connector includes a connector housing (10) having a cavity (12), terminal metal fixtures (40) each connected to an end of each core wire (22) of an electrical cable (20) and inserted into a terminal opening (131) in the cavity (12), a plug body (50) inserted into the cavity (12) and having a pair of through holes (53) for permitting each core wire (22) to pass through and a mold resin layer (100) formed around a rear end of the connector housing (10). The plug body (50) made of a resilient material contacts firmly with an interior of the opening (131), so that the plug body (50) can prevent the mold resin material from entering into the terminal metal fixtures when molding and also can perform waterproofing even if any clearance is formed between the mold resin layer (100) and the electrical cables (22). The plug body (50) and an accommodating chamber in the cavity (12) may be provided with tapered exterior and interior, respectively, thereby causing a close contact between the plug body (50) and the connector housing (10) by an injection pressure of a mold resin material. The plug body and accommodating chamber may not be provided with the tapered exterior and interior. A waterproofing seal (30) may be mounted on each terminal metal fixture (40) through the opening (131) in the cavity (12) so that the seal (30) makes close contact with the interior of the cavity (12). Even if any clearance may be formed between the mold resin layer (100) and the electrical cables (22) or the connector housing (10), the water which enters into the cavity (12) through the clearance is prevented from further advancing in the cavity by the waterproofing seal (30).

An ignition coil includes a center core, a secondary coil, a primary coil, and an outer core. The secondary coil and the primary coil are substantially coaxially arranged on the outer circumferential side of the center core. The secondary coil includes a secondary winding that is wound around a secondary spool. The secondary spool has a high voltage bracket that includes a secondary terminal. The primary coil includes a primary winding that is wound around a primary spool. The outer core is arranged on the outer circumferential side in the ignition coil. The secondary terminal includes a first connecting portion, which is in a bulb shape, in the tip end. The first connecting portion connects with an end portion of the secondary winding. The first connecting portion is covered with an electrically insulative resin.

A connector having an improved force for locking a shielding terminal. The connector (10) has a housing (20) and a ground terminal (50) is mounted into a shielded casing (C) after a shielding terminal (15) is partly locked in a cavity (21) of the housing (20) is partly locked by a locking portion (25) and then fully locked by touching pieces (59) of the ground terminal (50). The connector (10) can doubly lock the shielding terminal (15). Hence, the locking force for locking the shielding terminal (15) can be improved.

A connector has a housing (2) with cavities (4) for accommodating both crimping and insulation-displacement terminal fittings (5, 6). Locks (15) extend into the cavities (4) to elastically engage the terminal fittings (5, 6). A retainer mount opening (17) extends through an outer wall of the housing (2) and communicates with the cavities (4), and a retainer (3) is mounted in the opening (17) for doubly locking the terminal fittings (5, 6). Connecting portions (8) of the same shape are provided at the front of the terminal fittings (5, 6). The height of insulation-displacement portions (7) is shorter than that of the connecting portion (8) in the insulation-displacement terminal fitting (5), and terminal locks (18) of the retainer (3) engage with steps (8A) at the rear of the connecting portions (8). The retainer (3) can be pushed to a full locking position after the terminal fittings (5, 6) are mounted with the housing (2) to redundantly lock the terminal fittings (5, 6) in the cavities (4).
摘要:
An insulation displacement terminal fitting has V-shaped blade portions (17) each of which is formed by two blades (19) that interest at contacting edges (20). V-shaped cutting edges (21) of the blades (19) have different angles of inclination (&agr;, &bgr;) when viewed in the longitudinal direction of a wire (16). Thus, the cutting edges (21) contact a resin coating (16A) of the wire (16) at different timings while the wire (16) is being pushed in. The blades (19) of each blade portion (17) do not simultaneously come into contact with the resin coating (16A). Thus, a resistance during cutting can be small.
摘要:
A high voltage post terminal is accurately located within a support aperture during manufacturing processes by at least one inwardly directed projection to avoid assembly problems caused by sizing the entire aperture itself to locate the terminal with sufficient accuracy. By thus improving the concentricity of the high voltage coil components it is possible to achieve more reliable insulation between components at even relatively small-sized coils used for individual engine plug holes. An especially advantageous range of critical parameters has been discovered as achievable by using this more reliable manufacturing process.

An electrical terminal has inwardly directed blades (21,22) to cut through insulation and make contact with an electrical core wire. Two sets of axially spaced blades are provided to increase security. The front set of blades (21) is bent in from opposite sides whereas the rear set is bent up from the base. This configuration gives a short terminal length without risk of deformation when the usual wire barrels (13) are crimped.

A pressure contact terminal (10) has a pair of anterior and posterior pressure contact blades (17) formed thereon to define pressure contact grooves (20). A pushing-in member (23) is provided that fits into the terminal and has pressure contact grooves (27) formed on anterior and posterior end faces. The upper ends of the pressure contact grooves (27) have pressing-down members (28) for pressing down an electric wire (1) to a specified extent. After placing an end of the electric wire (1) on the pressure contact blades (17), the pushing-in member (23) is placed thereon and clamped using pliers P. Locking protrusions (31) enter locking holes (32) to retain the pushing-in member (23).
摘要:
A connector inspecting device that positively determines whether a metal terminal has been correctly inserted into the housing of the connector includes a slider provided in a checker housing in such a manner that it is movable and urged toward a connector by a compression spring. The slider includes a lance check pin protruded toward the connector and an electrical contactor that is integral with the lance check pin. When the connector is at a "normal position," the lance check pin goes in a lance bending space provided for a lance, so that the electrical contactor is electrically connected to the metal terminal. In the case where the metal terminal is set at a "half insertion position," the lance check pin abuts against the lance, which prevents the contact of the electrical contactor with the metal terminal.
摘要:
An ignition coil for an internal combustion engine has a first housing, a second housing, a holder, an insulating resin and a crack extension restrictor. The first housing encloses a center core, a primary coil and a secondary coil. The second housing has an install portion and a cylinder-shaped fitting portion fitted to a top cylindrical portion of the first housing. The holder is laid over top ends of the primary and secondary coils. The insulating resin is charged in an annular cavity defined at least by uppermost portions of the primary and secondary coils, the fitting portion and the holder and in contact with the fitting portion. The crack extension restrictor is formed by a part of the fitting portion and a part of the holder and disposed above the fitting faces of the fitting portion and the top end portion.
