Abstract: A connector is provided with a terminal element including a conductor-connecting section connectable to a conductor of an electric wire and a contact section capable conductively contacting with a corresponding terminal element of a counterpart connector, an electrically insulating body for supporting the terminal element while exposing the conductor-connecting section and the contact section, and an abutting member assembled with the body and bringing the wire conductor into abutment with the conductor-connecting section under pressure. The body includes a fitting portion capable of fitting with a counterpart connector while positioning the contact section with respect to the corresponding terminal element. The conductor-connecting section and the contact section are arranged to be aligned with each other generally orthogonal to a connector fitting direction defined by the fitting portion.

Abstract: An improvement in electrode reliability is realized by preventing over-etching on a peripheral lower portion of an electrode while maintaining the flow of steps of roughening a surface after forming the electrode on a semiconductor substrate. After a P-side electrode 4 is formed on a main surface 3a of a semiconductor substrate 3, a surface of the P-side electrode 4 is selectively covered with a protective film 12, after the semiconductor substrate 3 is cut into chips, the surface is roughened from above the protective film 12, the main surface 3a around the P-side electrode 4 and a side surface are roughened with a non-chemical treatment region 10 which is a non-roughened surface region being left in a peripheral portion of the P-side electrode 4 covered with the protective film 12, and thereafter the protective film 12 is removed.

Abstract: A body of a connector is constituted by combining a first support member for supporting a plurality of terminal elements with a second support member for supporting the first support member. The second support member has a plurality of bearing surfaces individually opposed to conductor-connecting sections of the terminal elements supported by the first support member. The first support member and the second support member are assembled with each other to arrange the wire conductors C between the conductor-connecting sections of the terminal elements and the corresponding bearing surfaces. An abutting member is assembled with the body. The abutting member has a pressing surface for uniformly pressing the conductor-connecting sections of the terminal elements supported by the first support member toward the corresponding bearing surfaces of the second support member.

Abstract: A connector housing (10) is molded using three molds (40, 50, 60). Mold parts (61a, 61b) pass from the exterior through a mold-removal hole (21) in a tube (14) of the housing and into a mold fitting space (41) in an interior mold (40). A beam (22) extends between two edges (21e) of the mold-removal hole (21) that are substantially normal to a removing direction of the first mold (40). Thus, the mold-removal hole (21) is divided into divided holes (21a, 21b) along a direction substantially normal to the removing direction of the first mold (40). Dimensions of the divided holes (21a, 21b) along the removing direction of the first mold (40) are small. Thus, an opening edge (41e) of the mold fitting space (41) of the first mold (40) is not likely to catch and damage the opening edge (21e) of the mold-removal hole (21).

Abstract: One 20 of a pair of connector housings 10, 20 connectable with each other is provided with a slider 40. The other connector housing 10 is provided with main follower pins 17 and auxiliary follower pins 18 located at different positions from the main follower pins 17. The slider 40 is formed with main cam grooves 44 for guiding the main follower pins 17 until the connection of the two connector housings 10, 20 is completed and auxiliary cam grooves 48 engageable with the auxiliary follower pins 18 at a desired timing within a period from an intermediate stage of the connection of the two connector housings 10, 20 to a completing timing of the connection.

Abstract: An attempt to fit an improper combination of housings (10, 30) together brings a projection (32R) of the wrong housing (30) into abutting engagement with an interference portion (15) in a fitting recess (12). Abutment surfaces (15a, 32Ra) are inclined in directions to move an inner peripheral surface of the fitting recess (12) towards an outer peripheral surface of the wrong housing (30). Therefore, the fitting recess (12) cannot deform and spread out, and the fitting of the wrong housing (30) cannot proceed by force.

Abstract: A beam (22) extends between two edges (21e) of a mold-removal hole (21) that extend substantially at right angles to a removing direction of a first mold (40). Thus, the mold-removal hole (21) is divided into divided holes (21a, 21b) along a direction substantially normal to the removing direction of the first mold (40). Dimensions of the respective divided holes (21a, 21b) along the direction substantially normal to the removing direction of the first mold (40) are small. Thus, an opening edge (41e) of a mold fitting space (41) of the first mold (40) is not likely to get caught by the opening edge (21e) of the mold-removal hole (21).

Abstract: A cable connector allows the electrical contacts thereof to come into elastic contact with a ground plate when the cable connector connecting with a shielded cable is fit-connected to a PCB connector through the ground plate. The contact effectiveness of the electrical contacts is improved so that a shield-ground path from the shielded cable to the ground plate has a low impedance. The connector is provided with electrical contacts which are composed of generally U-like bent spring plates. Each spring plate is supported at one end thereof on the shield shell, and comes into elastic contact with the ground plate when the cable connector is fitted into the mating connector.

Abstract: A connector has a housing (20) with cavities (32S) formed at a plurality of stages and configured for receiving terminals (26S). A retainer insertion opening (50) is formed in one side surface of the housing (20) for receiving a retainer (40). The retainer (40) has arms (42) for the respective stages of the cavities (32S). Locking projections (45) are formed on the arms (42) for engaging the corresponding terminals (26S). Transversely extending guide grooves (52, 52A) are formed in the front and rear surfaces of the arms (42), and ribs (57, 57A) are formed on side walls of the retainer insertion opening (50) for engaging the guide grooves (52, 52A) and preventing deformation of the arms (42).

Abstract: A device for breaking and dividing an enlarged bearing portion of a connecting rod into a main body portion and a bearing cap portion includes a split mold which is insertable into an aperture in the enlarged bearing portion. A pressing mechanism includes pressure caps engaging dramatically opposite points on the outer surface of the enlarged bearing portion at locations where the beating portion is to be broken and divided when a wedge is forced into the split mold.

Abstract: A connector has a housing (10) with a terminal accommodating portion (11) that has cavities (19) in which terminal fittings (13) are accommodated. A lock (20) for locking the corresponding terminal fitting (13) projects from the upper surface of each cavity (19). A rubber ring (30) for making a connector watertight is mounted on the outer surface of the terminal accommodating portion (11). A holder (50) is mounted before the rubber ring (30) on the terminal accommodating portion (11) and has a front wall (51) for supporting the front ends of the terminal fittings (13) at their front-limit positions. The holder (50) has a holding plate (52) that holds the front surface of the rubber ring (30) to prevent the rubber ring (30) from coming off.
