Abstract: An inner metal lock 30 is formed in an upper surface of a connecting portion 15 of an inner terminal 11 by cutting the upper surface and bending a cut portion outward to project obliquely backward. A locking hole 32 is formed in the upper wall of a dielectric element 13. Inner surfaces of an accommodating hole 25 of the dielectric element 13 are formed with ribs 34 to 37 for partly filling a clearance between the inner surfaces and the connecting portion 15 of the inner terminal 11. When the inner terminal 11 is pushed to a proper position in the accommodating hole 25 of the dielectric element 13 fixed in the outer terminal 12, the inner metal lock 30 restores to its original shape and fits into the second locking hole 32. As a result, the inner terminal 11 is locked in the dielectric element 13.

Abstract: A shielding terminal (15) is accommodated in a cavity (21) of a housing (20) in a connector (10) and is doubly locked by a lock (25) of the housing (20) and by a ground terminal (50). A recess (16D) is formed in a shielding shell (16) of the shielding terminal (15) during the formation of a locking claw (16B) for locking a dielectric element. The recess (16D) is narrower than the lock (25). Hence, the lock (25) neither enters nor gets caught by the recess (16D) during insertion of the shielding terminal (15) into the cavity (21). Therefore, an insertion resistance of the shielding terminal (15) can be reduced.

Abstract: A shielding terminal has a lock (14) mounted in an area extending from an opening (22) of a covering wall (21) to an outer crimping portion (23) of an outer terminal (12), and is fixed with respect to the outer terminal (12) by mounting plates (41) wrapping around the outer crimping portion (23). At this stage, a locking edge (45) at the leading end of the lock (14) faces a bottom end of the rear end of a connecting portion (15) of an inner terminal (11) so as to be engageable therewith for locking. Accordingly, even if the inner terminal (11) tries to come out of a dielectric element (13) upon action of a pulling force on a core (2) of a shielded cable (1), the rear end of the connecting portion (15) comes into contact with the locking edge (45) of the lock (14) to prevent such a movement.

Abstract: 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.

Abstract: A connector (10) has an improved operability by reducing an insertion resistance of a shielding terminal. The connector (10) has a housing (20) and a ground terminal (50). Contact pieces (56) of the ground terminal (50) are movable between a retracted position and a contact position and can be locked at the respective positions. A shielding terminal (15) can be inserted into the housing (20) at the retracted position where the contact pieces (56) and the shielding terminal (15) do not interfere with each other. Thus, an insertion resistance of the shielding terminal (15) can be reduced. Therefore, an assembling operability of the connector (10) can be improved.

Abstract: A connector is provided with crimping pieces that can be crimped into connection with a wire. The first and second crimping pieces (11, 12) are curved during crimping such that leading edges (11A, 12A) are inclined inwardly to a reduced diameter, and then are crimped into connection with a wire (W). The second crimping piece (12) is partly thinned at a position along its extending direction, to ensure that the leading edge (12A) can be bent inwardly. Thus, a crimping error resulting from such a deformation as to incline the leading edge (12A) in a direction opposite from an intended one can be prevented.

Abstract: A shielding terminal includes an inner terminal 11 to be connected with a core 2, an outer terminal 12 to be connected with a braided wire 4, a dielectric element 13 for insulating the two terminals 11 and 12 from each other, and a cover 14 to be mounted on an upper portion of the outer terminal 12. After the core 2 is fastened to an inner fastening portion 18 of the inner terminal 11 outside the outer terminal 12, the inner terminal 11 is inserted into the dielectric element 13. An outer fastening portion 22 of the outer terminal 12 is crimped into connection with a section 4A of the braided wire 4 folded back around an end of a sheath 5. In the center of the outer terminal 12, the upper surface is opened to provide an open space 21A. The fastened portion of the core 2 is covered on four sides by mounting the cover 14 to cover the open space 21A.

Abstract: A terminal is provided for stable mounting at a predetermined position of the leading end of a coaxial cable. The terminal 1 has rear side formed with a barrel 7 to be crimped into connection with the coaxial cable 2. A cover 11 is integrally provided before the barrel 7 for covering an exposed section of a core 3 of the coaxial cable 2. An embossed positioning portion 12 is formed between the barrel 7 and the cover 11. When the terminal 1 is mounted on a stripped end of the cable 2, the front end of a folded section 5A contacts a locking edge 12C of the positioning portion 12, thereby restricting any further insertion of the coaxial cable 2. Thus, the terminal 1 can be automatically positioned on the coaxial cable 2 with respect to the longitudinal direction of the coaxial cable 2.

Abstract: A connector is provided to enhance a force of a retainer for locking terminal fittings. The connector has a housing 1 formed with a retainer mount hole 12. A retainer 13 is provided for insertion into the retainer mount hole 12. Locking projections 15 are formed on the retainer 13 and are engaged with terminal fittings 16, to prevent the terminal fittings from coming out of the housing 1. End locking portions 19 are provided at the opposite ends of the retainer 13, and intermediate locking portions 20 are provided between the end locking portions 19. The female housing 1 is provided with end and intermediate receiving portions 21, 22 corresponding to the end and intermediate locking portions 19, 20. Partial and full locking portions 23, 24 for holding the retainer 13 in its partial and full locking positions are formed in the end and intermediate receiving portions 21, 22.

Abstract: An inner metal lock 30 is formed in an upper surface of a connecting portion 15 of an inner terminal 11 by cutting the upper surface and bending a cut portion outward to project obliquely backward. A locking hole 32 is formed in the upper wall of a dielectric element 13. Inner surfaces of an accommodating hole 25 of the dielectric element 13 are formed with ribs 34 to 37 for partly filling a clearance between the inner surfaces and the connecting portion 15 of the inner terminal 11. When the inner terminal 11 is pushed to a proper position in the accommodating hole 25 of the dielectric element 13 fixed in the outer terminal 12, the inner metal lock 30 restores to its original shape and fits into the second locking hole 32. As a result, the inner terminal 11 is locked in the dielectric element 13.

Abstract: Chained terminals (10) are formed such that a multitude of terminal fitting pieces (12) are connected in parallel with a lateral edge of a carrier (11) in the form of a long strip, and are wound around and dispensed from a reel (20) with an interlayer sheet (21) laid underneath. Each terminal fitting piece (12) is formed with projections (17) projecting in a direction normal to a radial direction of the reel (20), i.e. a direction along the plane of the interlayer sheet (21). Thus, the projections (17) neither stick into the interlayer sheet (21) nor are deformed by being caught in by the interlayer sheet (21). Protecting portions (19) are aligned with the projections (17) but extend further from the carrier (11) for protecting the projections (17).

Abstract: A shielding terminal has a lock (14) mounted in an area extending from an opening (22) of a covering wall (21) to an outer crimping portion (23) of an outer terminal (12), and is fixed with respect to the outer terminal (12) by mounting plates (41) wrapping around the outer crimping portion (23). At this stage, a locking edge (45) at the leading end of the lock (14) faces a bottom end of the rear end of a connecting portion (15) of an inner terminal (11) so as to be engageable therewith for locking. Accordingly, even if the inner terminal (11) tries to come out of a dielectric element (13) upon action of a pulling force on a core (2) of a shielded cable (1), the rear end of the connecting portion (15) comes into contact with the locking edge (45) of the lock (14) to prevent such a movement.

Abstract: A shielded connector is provided with an improved shielding characteristic. The shielded connector includes male and female shielded connectors (10a, 10b). A section of an inner conductor (51) of a shielded cable (50) that is not covered by an outer conductor (52) and a portion of an inner terminal (20a) at and near an inner crimping portion (24) that is fastened to the leading end of the inner conductor (51) are covered on three sides by a covering portion (45). Accordingly, shielding characteristic can be improved remarkably. By connecting the male and female shielded connectors (10a, 10b) with opening surfaces of the covering portions (45) thereof faced in opposite directions, radiation characteristic can be balanced. Therefore, an influence on a high-frequency signal transmitting through the inner conductor (51) can be reduced when it is passing through the shielded connectors (10a, 10b), with the result that shielding characteristic can be improved.

Abstract: A terminal is provided for secure electrical connection to a shielded cable. The outer conductor 52 of the cable 50 is exposed and folded onto the sheath. A folded portion 55 is placed on a bottom portion 48 of the terminal while a bottom projection 61 at the bottom portion 48 of an outer terminal 40 bites into the folded portion. A crimping piece 46 of the outer terminal 40 is brought into close contact with the outer surface of the folded portion 55 and an upper projection 62 on the crimping piece 46 bites into a sheath 54 of the folded portion 55. A crimping piece 47 is brought into close contact with the outer surface of the folded portion 55 and the end thereof is placed on that of the crimping piece 46. The outer crimping portion 45 squeezes the sheath 54 and is crimped while being held in close contact with the sheath 54 beneath the folded portion 55, and the two projections 61, 62 bite into the sheath 54.

Abstract: An inner terminal 11 is accommodated in an accommodating portion 20 of an outer terminal 12 via a dielectric element 13. A core 2 of a shielded cable 1 is fastened to an inner fastening portion 18 of the inner terminal 11 outside the outer terminal 12, and then the inner terminal 11 is inserted into the dielectric element 13. A braided wire 4 is folded back around an end of a sheath 5, and an outer fastening portion 22 of the outer terminal 12 is fastened to a folded portion 4A thereof. A covering wall portion 21 in which only the upper surface is open is provided between the accommodating portion 20 and the outer fastening portion 22 of the outer terminal 12, and the inner fastening portion 18 is located in the covering wall portion 21.

Abstract: A connector is provided with a ground terminal, and a side type retainer is mountable in the connector. A connection element receptacle 20 for accommodating an electrical connection element 3 is provided inside a connector housing 2. A retainer 4 for locking the electrical connection element 3 is mounted in a retainer mount hole 25 formed in the upper surface of the connector housing 2. Further, a ground terminal receptacle 29 for accommodating a ground terminal 5 is provided in the bottom wall of the connection element receptacle 20. In this way, since the retainer 4 is assembled at the side of the electrical connection element 3 opposite from the ground terminal 5, it can be constructed as a so-called side retainer.

Abstract: A connector is provided to ensure the strength of a tubular engaging portion and to prevent a breakage of a locking portion during connection with a mating connector. The connector includes a terminal fitting 20 that is inserted to a proper position in a tubular engaging portion 11 of a housing. Locking portions 33 are formed on the outer surfaces of the terminal fitting 20 and are engaged with lock recesses 18 formed in the inner surfaces of the engaging portion 11. As a result the terminal fitting 20 is held so as not to come out. The locking recesses 18 are formed by recessing small portions of the inner surfaces of the engaging portion 11 sufficient to be engaged with the leading ends of the locking portions 33 and, accordingly, do not bring about a reduction in the strength of the engaging portion 11.
