Abstract: A joint connector includes a housing that includes terminal chambers. At least two neighboring joint terminals are housed in terminal chambers neighboring among the terminal chambers, respectively. Each of the neighboring joint terminals includes a wire-crimping portion, a terminal body housed in a terminal chamber among the plurality of terminal chambers, and a pair of first and second contact portions, respectively. The first contact portion of one of the neighboring joint terminals is electrically contacted with the second contact portion of another of the neighboring joint terminals. A pair of spring tabs is formed on both sidewalls of the terminal body and contacts with opposed inner surfaces of the terminal chamber, respectively, by an elastic restoration behavior. According to the joint connector, an increase of a contact resistance to be generated by vibrations and temperature variations can be sufficiently restricted.

Abstract: A joint terminal is to be used in a connector housing in a plurality. The joint terminal includes a wire-crimping portion, a terminal body to be housed in a terminal chamber of the connector housing (the terminal body includes a bottom wall and a pair of sidewalls perpendicularly extended from both side ends of the bottom wall, respectively) and a pair of first and second contact portions laterally extended outward from the pair of sidewalls of the terminal body, respectively. In the joint terminal, a pair of front walls is perpendicularly extended from front ends of the sidewalls toward each other so that end edges of the front walls face to each other. The sidewalls 14 are bent, at a maximum, until the end edges of the front walls contact with each other. Therefore, the joint terminal can become structurally strong.
