    Abstract: It is aimed to provide a connector structure enabling the replacement of an STP cable (10B) and a UTP cable (10A) without making a large structural change. UTP connection terminals (21A) to be connected to respective wires (11) of a UTP cable (10A) have the same shape and are accommodated in a pair of accommodating portions (26) of a UTP dielectric (22A) such that insertion areas (53) for male terminals (91) are close to each other in a width direction. STP connection terminals (21B) to be connected to respective wires (11) of the STP cable (10B) have the same shape and are accommodated into the pair of accommodating portions (26) of a STP dielectric (22B) such that insertion areas (53) for male terminals (91) are arranged more apart from each other in the width direction than in the case of the UTP connection terminals (21A).

    Abstract: A shield connector includes an inner housing to hold terminals connected to wires and a shield shell to accommodate the inner housing and the end of the shielded cable. The shield shell includes a base and a cover to cover the inner housing. The base includes a bottom plate to cover a lower surface of the inner housing and base-side plates to cover side surfaces of the inner housing. A front-rear restricting convex portion extends vertically and engages a front-rear restricting cut to restrict relative movements of the inner housing and the base in a front-rear direction. A vertical restricting convex portion engages a vertical restricting hole to restrict relative vertical movements of the inner housing and the base.

  • Publication number: 20200059033
    Abstract: A connector has parts that can be used in common as much as possible in different specifications to reduce cost and to facilitate parts management. In a first specification having a high shielding function, a terminal fitting (20) connected to a shielded electric wire (15) is accommodated in a dielectric (23). The dielectric (23) is surrounded by an outer conductor (40) that is connected to a braided wire (18). The second specification requires no shielding function, and thus the outer conductor (40) is not used. Rather, a sub-housing (70) having the same shape and size as the outer conductor (40) of the first specification is used. The sub-housing (70) is configured to accommodate and retain the terminal fitting (20) and is locked in a same retained state as in the first specification when accommodated in a common housing (10) used in both specifications.

  • Patent number: 10566741
    Abstract: A shielded connector includes a dielectric module (20) having an L-shaped terminal fitting (24) attached to a dielectric (21) and an outer conductor (30) that houses the dielectric module (20). The outer conductor (30) has a housing (31) with a first opening (35) at a front, a second opening (36) at a rear of a lower surface, and an insertion port (37) at a rear end communicating with the second opening (36). A lid (43) is continuous with an edge of the insertion port (37) and is displaced from an open position where the insertion port (37) is opened to allow insertion of the dielectric module (20) into the module housing (31) to a closed position where the insertion port (37) is closed. With the lid (43) closed, an outer plate (47) on the lid (43) covers the holding portion (41) on the module housing (31) to prevent accidental release.

  • Publication number: 20190319406
    Abstract: A connector is capable of replacing an STP cable (10B) and a UTP cable (10A) without a large structural change. UTP connection terminals (21A) are accommodated in accommodating portions (26) of a UTP dielectric (22A) that are close to each other in a width direction. Thus, elastic contact pieces (32) thereof are located inside and close to each other in the width direction, while receiving portions (31) are located outside and spaced from each other in the width direction. STP connection terminals (21B) are accommodated in accommodating portions (26) of an STP dielectric (22B) that are spaced more apart in the width direction than those of the UTP dielectric (22A). Thus, elastic contact pieces (32) thereof are located outside and are spaced from each other in the width direction, while receiving portions (31) thereof are located inside so as to be close to each other in the width direction.
