Abstract: An electrical connection device includes a connector unit (2) having first connectors aligned in an arrangement direction, second connectors and a connecting tool (30). The connecting tool (30) detachably holds the second connectors in an alignment corresponding to that of the first connectors. One of the connector unit (2) and the connecting tool (30) includes a guided portion (5), and the other includes a guiding portion (50). The guiding portion (50) includes a receiving portion for receiving the guided portion (5) in a receiving direction, a connection guiding portion for guiding the guided portion (5) to displace the connector unit (2) and the connecting tool (30) in a connector connecting direction as the connector connecting tool (30) is operated with respect to the connector unit (2) in the arrangement direction, and a separation allowing portion for allowing separation of the guided portion (5) from the connection guiding portion.

Abstract: A movable member (30) provided in a housing (10) is formed with a cover (32) configured to cover inserting edges (45) on a tip of a circuit board (41) in an inserting direction into a board accommodation space (15) when the circuit board (41) is inserted into the board accommodation space (15) and a receiving surface (34) configured to move the movable member (30) integrally with the circuit board (41) to a back side of the board accommodation space (15) by being pushed by the circuit board (41). The movable member (30) and the circuit board (41) are formed with locks (38, 46) configured to move the movable member (30) integrally with the circuit board (41) in a withdrawing direction from the board accommodation space (15) by locking each other.

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.

Abstract: An electrical connection device includes a first connector (C1) having a first housing (10), a second connector (C2) having a second housing (20) for receiving the insertion of the first housing (10), and a connection detecting tool (30). The first housing (10) includes a housing body (12), a lock (14) having a tool restraining portion (14d) and a displacement restricting portion (16) for blocking an insertion allowing displacement of the lock (14). The connection detecting tool (30) is held at an operating position to resiliently deform the displacement restricting portion (16) to allow the insertion allowing displacement. The tool restraining portion (14d) restrains the connection detecting tool (30) at the operating position so as not to be separable while allowing the separation of the connection detecting tool (30) from the operating position as the lock (14) resiliently returns to a lock position.

Abstract: It is aimed to prevent connectors in a connected state from being easily separated. A connector (A) includes a male housing (10) including a receptacle (12), a female housing (30) to be connected to the male housing (10) by being inserted into the receptacle (12), and a retainer (36) (movable locking member, locking means) and a lock receiving portion (19) (locking means) provided on the male housing (10) and the female housing (30) and configured to lock the male housing (10) and the female housing (30) in a connected state by being locked inside the receptacle (12). The locking of the retainer (36) and the lock receiving portion (19) is released by an unlocking tool (40) inserted into the receptacle (12).

A connector (CO) includes a twisted pair cable formed by twisting a pair of wires, female terminals (9A, 9B) connected to respective ends of both wires (W) of the twisted pair cable, a housing (15) formed with cavities (18) for individually accommodating the female terminals (9A, 9B), and a locking lance (13) deflectably arranged in the housing (15) and capable of locking the female terminals (9A, 9B). A pair of the female terminals (9A, 9B) connected to the both wires (W) of the twisted pair cable are accommodated into the cavities (18) adjacent in a Y direction and the locking lance (13) integrally and interlockably formed to straddle between the adjacent cavities (18) is formed in the adjacent cavities (18).

A dielectric (10) has a holding member (11) and a cover (27) united in a direction intersecting an axial direction of the wires (38) and accommodates the inner conductors (35). Guide recesses (17) are formed on the holding member (11) and extend in a front-rear direction. Guide ribs (33) are formed on the cover (27) and can slide in contact with the guide recesses (17) to allow relative displacement of the holding member (11) and the cover (27) in the front-rear direction while keeping the holding member (11) and the cover (27) united. Guides (19) bring the holding member (11) and the cover (27) closer together in a uniting direction while displacing the cover (27) from a temporary assembled position to a proper assembled position in the front-rear direction.

Abstract: It is aimed to make connectors accommodating wires conductive to each other without using terminals. Connectors each including wires (2) formed with core exposed portions (2B) by removing parts of coatings (2A) and a connector housing (1) for accommodating the wires (2) while exposing the core exposed portions (2B) in an opening (4) are stacked with the openings (4) facing each other. An operation hole (5) is formed on a side opposite to the opening (4) in the both connector housings (1). Electrodes (9) of a welding machine are inserted through the both operation holes (5) and the core exposed portions (2B) corresponding in a stacking direction are welded to each other. In this way, the wires (2) can be directly connected between the both connectors without using terminals.

Short-circuit preventing walls (18) configured to partition between cavities (11) adjacent in an arrangement direction are provided in a retainer insertion hole (15). A retainer (13) is provided with a plurality of frame-like portions (20) along the arrangement direction of the respective cavities (11). Each frame-like portion (20) is formed to be able to communicate with the corresponding cavity (11). Escaping grooves (32) are formed along a mounting direction of the retainer (13) between the frame-like portions (20) adjacent in the arrangement direction. Escaping grooves (32) are open on front end parts in the mounting direction of the retainer (13) such that the retainer (13) is mountable into the retainer insertion hole (15) while avoiding interference with the short circuit preventing walls (18).

Abstract: In the process of mounting a joint terminal (5) into a first terminal accommodating portion (16) of a housing (15), tab terminals (6) of the joint terminal (5) move forward along tab entrance paths (26) formed in the housing (15). The tab entrance path (26) is formed with a cam portion (27) spiral about an axis thereof. As the tab terminal (6) moves forward in the tab entrance path (26), a follower portion (8) formed at an intermediate position of the tab terminal (6) is guided by the cam portion (27). Thus, the tab terminal (6) is twisted about an axis. In this way, resilient contact pieces (14) of female terminals (9A, 9B) face the tab terminals (6) in a plate surface direction of the tab terminals (6) and are connected to the tab terminals (6).
