It is aimed to enable a functional member to be properly mounted on a housing. A connector includes terminal fittings (24) and a housing (10) into which the terminal fittings (24) are to be mounted. The housing (10) is formed with a lock arm (15) having a rear end part serving as an operating portion (18) for unlocking. The housing (10) includes a protecting portion (20) for covering the operating portion (18). The protecting portion (20) is formed with a receiving portion (23). A retainer (30) is mounted on a rear end part of the housing (10). The retainer (30) is formed with a fit-in portion (38) fittable to the receiving portion (23) when the retainer (30) is properly mounted on the housing (10).

An electrical connector includes a plurality of cylindrical electrical terminals connected to ends of a plurality of first electrical cables, a housing defining a plurality of housing terminal cavities in which the plurality of cylindrical electrical terminals is disposed, and a cover attached to the housing having a plurality of cover cavities that is axially aligned with the plurality of housing terminal cavities. The plurality of cover cavities is configured to receive the plurality of cylindrical electrical terminals as it is inserted within the plurality of housing terminal cavities.

By a simple configuration, contact members can be well retained with a housing in a mutually opposed state, and productivity can be improved. When the contact members in the mutually opposed state are to be attached to the housing, a contact retainer prepared by molding in advance is used by disposing the contact retainer in part of the contact opposed region. As a result, the contact members are stably retained in the mutually opposed state even in injection molding molds. Even in a case in which the contact members normally cannot be retained in the mutually opposed state in the injection molding molds, the housing and the contact members can be integrally molded by well retaining the contact members in the mutually opposed state by using the contact retainer and a contact retainer auxiliary and executing an injection molding process.

A connector assembly includes a cap housing in which a first terminal is disposed, a plug in which a second terminal is disposed, and a terminal position assurance (TPA) member. The plug has a first end portion and a second end portion opposite the first end portion. The second end portion is inserted into the cap housing. A first end portion of the cap housing and the first end portion of the plug to which a wire is connected are each a coupling target. The TPA member is disposed at the coupling target. The TPA member includes a first block and a second block partitioned from one another in a circumferential direction of the wire.

An abutting portion is provided as a portion of an edge portion of an upper wall portion, and abuts against an edge portion of a first side wall portion when the upper wall portion bends toward the inside of a tubular wall portion. The projection portion projects from the upper wall portion, and restricts insertion of the tubular wall portion toward the back of the housing by abutting against the housing when the tubular wall portion is inserted into the housing in an orientation different from a predetermined insertion orientation. The engaging portion is configured to be able to engage with an engaged portion provided on an inner side of the housing. The engaging portion is provided on the tubular wall portion at a position that shifted from or separated from the projection portion in the longitudinal direction of the tubular wall portion.

A heavy-duty plug-in connector has a ground terminal that can be conveniently assembled and can comprise the greatest possible number of electrical crimp plug-in contacts (4,5). For this purpose, ground plug-in contacts (4′, 5′), likewise of a crimping configuration, are fitted in formations (13, 13′, 23, 23′) of the contact carriers (1, 2) for electrical contacting with metallic protective earthing elements (3, 3′, 3″, 3″). For said contacting, the formations (13, 13′, 23, 23′) have a respective opening (130, 130′) or passage (230, 230′). In the formations (13, 13′, 23, 23′), not only ground plug-in contacts (4′, 5′) but also further plug-in contacts (4, 5) are arranged, so that the number of plug-in contacts (4, 5) of the plug-in connector is increased considerably.

The present invention provides a terminal block that can simplify parts management. This terminal block 1 comprises a busbar assembly 50 that has: busbars 51, 52 made of metal; and a holding unit 53 that exposes tip parts 51b, 52b and base parts 51a, 52a of the busbars 51, 52 and holds the busbars 51, 52. Also, the terminal block 1 comprises a housing 10 in which the base parts 51a, 52a of the busbars 51, 52 are inserted and to which the holding unit 53 is fixed.

A joint connector, including: a connector housing; a joint terminal; a terminal holder; and a lock arm that is formed in an outer peripheral wall of the connector housing, in which a rear end portion of the terminal holder is provided with convex portions that protrude rearward from a rearmost end edge of the connector housing in a proper assembled state of the terminal holder with respect to the connector housing.

A contact insertion machine includes a contact feeder having a feed finger configured to feed contacts of a power connector assembly in a feed direction along a feed track during a contact loading process. The contact insertion machine includes a power connector assembly holder holding a housing of the power connector assembly and movable relative to the feed track to position the housing to receive the contacts in a contact stack. The contact insertion machine includes a contact retention plate located upstream of the power connector assembly holder having a contact insertion port therethrough. The contact insertion port is aligned with the feed track downstream of the feed track. The power connector assembly holder is movable relative to the contact retention plate to position the housing to receive the contacts through the contact insertion port.

An electrical connector comprises a body, a terminal positioning member provided at a rear end of the body and a first group of terminals mounted in terminal grooves of the body. The terminal positioning member comprises a first spacing rib and a second spacing rib. The first group of terminals comprises signal terminals and ground terminals. The signal terminals and the ground terminals each comprise a contact portion, a retaining portion and a tail portion, the retaining portion connecting the contact portion and the positioning portion, the positioning portion connecting the retaining portion and the tail portion. The first spacing rib extends between the positioning portions of the adjacent signal terminals, the second spacing rib extends between the positioning portion of the signal terminal and the positioning portion of the adjacent ground terminal and the first spacing rib is longer than the second spacing rib.
