  • Patent number: 10236596
    Abstract: A connection terminal includes a terminal main body, a contact member, a locking structure, and a position adjustment structure. The terminal main body is electrically conductive and includes a female connector. The contact member is disposed, in a first region of an internal space of the female connector, to face an inner circumferential surface of the female connector. The locking structure holds the contact member at a position thereof after completion of housing of the contact member in the internal space. The position adjustment structure adjusts the position of the contact member in the internal space. The position adjustment structure includes a locked holder disposed in the contact member and a locking holder disposed in the terminal main body.

  • Patent number: 10193257
    Abstract: A connection terminal includes a terminal main body having a female connector provided with an internal space into which a male connector is inserted and a contact member accommodated into the internal space. The contact member has at least one first locked part and at least one second locked part. The female connector has a first locking part that is arranged on a side in an insertion direction of the male connector and locks the movement of the first locked part in the insertion direction, and a second locking part that is arranged on a side opposite to the side in the insertion direction relative to the second locked part of the contact member after the completion of being accommodated and locks the movement of the second locked part in a removal direction in order to maintain the accommodated state of the contact member.
