Abstract: A connector (1) includes a dielectric (10) having conductor accommodation chambers (17) laterally partitioned by a separation wall (15), inner conductors (36) individually accommodated in the conductor accommodation chambers (17), a body (11) made of synthetic resin, constituting the dielectric (10) and formed with the separation wall (15) and the conductor accommodation chambers (17), and a front wall (28) made of synthetic resin, constituting the dielectric (10) and mounted on a front part of the body (11) to close front end openings of the conductor accommodation chambers (17). The separation wall (15) is made of a material having a lower dielectric constant than the front wall (28), and the front wall (28) is made of a material having a higher mechanical strength than the separation wall (15).

Abstract: In a connector, tabs (18) of male terminal fittings (16) are inserted into a female housing (30) and connected to female terminal fittings (34) by bringing a male housing (10) and the female housing (30) closer to each other in a facing positioning relationship. The male housing (10) is provided with a movable member (20) movable with the tabs (18) relatively displaceably passed therethrough, and a surface of the movable member (20) facing the female housing (30) is formed with a positioning projection (26), and a surface of the female housing (30) facing the movable member (20) is formed with a positioning recess (31) to be fit to the positioning projection (26) with front end parts of the tabs (18) passed through the movable member (20) and held out of contact with the female housing (30).

Abstract: An electrical connection device reliably detects a connected state of connectors and includes first and second connectors (C1, C2) first and second housings (10, 20) and a connection detector (30). The first housing (10) includes a detector restraining portion (14b). The second housing (20) includes a restraint releasing portion (26) for restraining the connection detector (30) until the first housing (10) reaches a connection position and releasing the restraint when the connection position is reached. The first housing (10) includes a connection allowance switch having a connection preventing portion (19). The connection allowance switch is deformable to displace the connection preventing portion (19) from a connection preventing position to a connection allowing position.

Abstract: It is aimed to detect a mounted state of a second terminal fitting in a terminal unit in which the second terminal fitting is mounted in a terminal holding member. A connector includes an interfering projection (25) formed on a retainer (21). When a second terminal fitting (50) of a terminal unit (30) is properly mounted in a terminal holding member (31), the retainer (21) is displaceable from a partial locking position to a full locking position without the interfering projection (25) interfering with the second terminal fitting (50). When the second terminal fitting (50) is improperly mounted in the terminal holding member (31), the interfering projection (25) interferes with the second terminal fitting (50), thereby restricting a displacement of the retainer (21) to a full locking position.

Abstract: A male internal conductor and a female internal conductor are reliably connected. When female-side and male-side dielectric bodies (16, 41) approach each other in an opposing positional relationship, a tab (32) of a male internal conductor (30) is inserted into a female-side dielectric body (41) and connected to a female internal conductor (42). The female-side dielectric body (41) has an opposing surface (41S) facing the male-side dielectric body (16) and formed with a female-side positioning portion (47). The male-side dielectric body (16) has an opposing surface (22S) facing the female-side dielectric body (41) and formed with a male-side positioning portion (25) which is disposed ahead of the tab (32) and which can be fitted with the female-side positioning portion (47) in a state where the tab (32) is not in contact with the female-side dielectric body (41).
