摘要： PROBLEM TO BE SOLVED: To prevent contact failure from occurring between a tab part and a tab contact part if a terminal is shifted in a terminal housing chamber. SOLUTION: In this pressure-contact joint connector, a terminal 6 is inserted and housed in a terminal housing chamber 5 in each connector housing 1, and by moving two connector housings 1 in directions to bring a connection surface 1a of one connector housing 1 close to a connection surface 1b of the other, the connector housings 1 are connected in multistage relation while a tab part 6c of one of vertically opposed terminals 6 makes contact with a tab contact part 6d of the other when the two connector housings 1 are in the position of connection. A contact surface 20 extending in the terminal insertion/extraction direction S of each terminal 6 is formed on its tab part 6c, each tab contact part 6d is adapted to be elastically deformable in an orthogonal direction T to the terminal insertion/extraction direction, and each tab contact part 6c makes contact with the contact surface 20 of an opposite standing tab part 6c by being elastically deformed in the orthogonal direction T to the terminal insertion/extraction direction.

摘要： PROBLEM TO BE SOLVED: To protect a connector terminal with the structure that a contact part of a terminal is exposed from a housing by connecting a pair of covers, which are positioned in each side of a main body, with a band part, and surrounding a contact part of the terminal, which is projected from the main body, with the pair of covers and the band part. SOLUTION: In a base housing 12 integrally formed with a band part 27, a pair of covers 21, 21 are connected to each other by a band part 27. During the time till the base housing 12 is inserted into a housing case, a contact part 17 of a terminal 11, which is projected out of the base housing 12, is protected by the pair of covers 21, 21 and the band part 27. With this structure, since the external force is not applied to the contact part 17 of the terminal 11 during the time of handling the base housing 12, namely, during a process for manufacturing a wire harness, the contact part 17 of the terminal 11 is secured protected. As a result, normal fitting to a counterpart terminal is enabled.
