A joint connector includes a housing comprising a plurality of insertion holes. A first isolation terminal is inserted into a first insertion hole of the plurality of insertion holes. The first isolation terminal is configured to block current flow. A connection terminal is inserted into a second insertion hole of the plurality of insertion holes. The second insertion hole is adjacent to the first insertion hole and is electrically connected to the first isolation terminal.

An elastic terminal ferrule includes an annular body, a limit structure formed on the annular body, and a mating limit structure formed on the annular body for mating with the limit structure. When the annular body is in a natural state without radial expansion, the limit structure and the mating limit structure are spaced apart from each other in a circumferential direction. When the outer diameter of the annular body is expanded to a predetermined value, the limit structure and the mating limit structure abut against each other in the circumferential direction to prevent further radial expansion of the elastic terminal ferrule.

An electrical connector assembly is provided. The electrical connector assembly includes a housing and two electrically conductive connection members. Each of the two electrically conductive connection members is arranged in the housing and is connected to at least one electrically conductive cable. The electrically conductive connection member has an electrically conductive terminal, a cable connection member, and a terminal holding member. The electrically conductive terminal has two leaf springs that are opposite to each other and a U-shaped connection part connected between the two leaf springs. The cable connection member is bent and has a first connection part and a second connection part. The terminal holding member has two sheet bodies that are arranged opposite to each other and a plate-shaped connection part connected between same sides of the two sheet bodies, so that the terminal holding member is in a shape of an inverted U.

It is aimed to provide a female terminal of a novel structure having a large degree of freedom in setting a pressure contact force between a male terminal including a columnar connecting portion and a female terminal including a tubular connecting portion and capable of stably ensuring a large contact area between the male and female terminals. A female terminal 10 includes a tubular connecting portion 24 having a first peripheral wall portion 12 and a second peripheral wall portion 14 arranged to face each other and to be conductively connected to a cylindrical connecting portion 22 of a male terminal 20, a biasing means 64 for biasing the first and second peripheral wall portions 12, 14 in directions approaching each other, and an arcuate protrusion 34 provided on an inner surface 18 having an arcuate cross-section of at least one of the first and second peripheral wall portions 12, 14 and projecting radially inward while extending in a circumferential direction of the inner surface 18. The first and second peripheral wall portions 12, 14 are separably displaceable against a biasing force of the biasing means 64.
