A female connector (10) includes a female housing (11), female terminal fittings (26) to be inserted into the female housing (11) from behind, and a retainer (33) to be mounted into the female housing (11). The female housing (11) includes a lock arm (17) having a rear end part serving as an operating portion (20) for unlocking, and the retainer (33) is formed with a covering portion (35) for covering at least a part of the operating portion (20).

An electrical connector includes a housing and a terminal module mounted in the housing. The terminal module includes an insulative body, a fixed part mounted on the insulative body extending along a back-to-front direction, and a plurality of terminals. The fixed part defines a mounting hole through the fixed part along front-to-back direction. The insulative body has a connecting arm inserting into the mounting hole for position the fixed part on the insulative body. The fixed part defines a pilot hole extending to the mounting hole, and glue is disposed into the pilot hole to bond the fixed part with the insulative body.

A connector 10 includes a plurality of terminals 12, an inner housing 20 for holding the plurality of terminals 12, a tubular outer housing 30 for covering the inner housing 20, and a bolt B1 for fastening the inner housing 20 and the outer housing 30 by being inserted up to the inner housing 20 while being passed through the outer housing 30 from outside of the outer housing 30. The inner housing 20 is formed with a plurality of cavities 22 for respectively accommodating the plurality of terminals 12 and a recess for accommodating the bolt B1, and the plurality of cavities 22 and the recess are partitioned from each other.

A terminal-equipped electric wire includes an electric wire that includes a conductor, a terminal connected to the conductor, and a shell attached to the terminal. The terminal includes a grip portion that pinches the conductor. The shell includes a pressing portion that presses at least a portion of the grip portion toward the conductor. The grip portion and the conductor are joined with an alloy layer. The alloy layer contains a Cu—Sn alloy.

An ergonomically friendly terminal position assurance device for use with an electrical connector. The device includes a terminal position assurance device for use with an electrical connector. The device includes a terminal engaging section and an engagement section. The terminal engaging section has a first end and an oppositely facing second end. The engagement section extends from the first end and has a bearing surface, the bearing surface has a surface area which is wider than the width of the terminal engaging section. The engagement section extends at least part of the length of the terminal engagement section. The bearing surface of the engagement section is configured to allow an assembler to push the terminal position assurance device during assembly of the electrical connector in an ergonomically friendly manner.

An electrical connector includes an insulative housing, a plurality of contacts retained in the insulative housing, a fastener and a first sealing ring. The insulative housing has a rear section extending backwardly. The rear section has a rear space and a first peripheral wall around the rear space. Each contact has a connecting leg extending into the rear space. The fastener has a mating section to engage with the rear section and a board receiving chamber extending therethrough along a front to back direction. The fastener has a fixed position on the insulative housing, and as moving the fastener to the fixed position, the connecting legs are pressed into the board receiving chamber for electrically connecting with the flexible printed circuit board, and the first sealing ring is sealed around the junction of the contacts and the flexible printed circuit board.

A terminal position assurance member for use with an electrical connector. The terminal position assurance member includes a terminal engagement section with terminal engaging projections. At least one first latch arm extends from the terminal engagement section. At least one second latch arm extends from the terminal engagement section and is spaced from the at least one first latch arm. The at least one first latch arm engages a portion of a first electrical connector to secure the terminal position assurance member to the first electrical connector when terminals of the first electrical connector are properly positioned. Alternatively, the at least one second latch arm engages a portion of a second electrical connector to secure the terminal position assurance member to the second electrical connector when terminals of the second electrical connector are properly positioned.

The present application provides a charging socket including a socket body, the socket body is provided with a charging end configured to connect to a charging plug, a conversion end configured to connect to a battery pack, and a terminal accommodating cavity communicated with and between the charging end and the conversion end; the conversion end is provided with a mating installation groove configured to mount an adapter plug and configured to pluggably connect with the adapter plug. In the charging socket provided in the present application, only the adapter plug is required to be pulled out from the mating installation groove on the socket body when the charging terminal mounted in the terminal accommodating cavity needs to be repaired or replaced, thereby removal of the connection between the charging terminal and the battery pack is completed, which effectively reduces the difficulty of disassembly and assembly. Therefore, this process is simple, improves the working efficiency, and reduces the maintenance cost.

A terminal is inserted between a first contact and a second contact, formed in the interior of a mating terminal. The terminal includes a plurality of first projections and a second projection. The first projections are disposed on the first surface, and protrude in an orthogonal direction orthogonal to an insertion direction while linearly extending in the insertion direction in which the terminal is inserted into the mating terminal. The second projection is disposed on the second surface, and protrudes in the orthogonal direction. The first projections and the second projection are disposed at positions at which the first projections and the second projection come into contact with the first contact and the second contact, respectively, in a state in which the terminal has been connected to the mating terminal.
