Connection terminal and connector
The present disclosure provides a connection terminal and a connector capable of suppressing a temperature increase during energization. A vehicle-side connector 10 includes a vehicle-side terminal 50 made of metal and a heat storage body 60 held in the vehicle-side terminal 50 . The vehicle-side terminal 50 includes a terminal connecting portion 51 to be electrically connected to a charger-side terminal 82 , a wire connecting portion 54 to be electrically connected to a wire 70 and a holding portion 56 integrally formed to the terminal connecting portion 51 and the wire connecting portion 54 . The heat storage body 60 is held in the holding portion 56.
1. A connection terminal, comprising:
a terminal made of metal; and
a heat storage body including a case held in or on the terminal, a heat storage material being accommodated inside the case,
wherein:
the case includes a front end and a rear end opposite the front end,
the terminal includes:
a terminal connecting portion to be electrically connected to a mating terminal;
a wire connecting portion to be electrically connected to a wire; and
a holding portion integrally formed to and positioned between the terminal connecting portion and the wire connecting portion,
the terminal connecting portion, the holding portion, and the wire connecting portion are linearly aligned in a row along a front to rear direction, and
the case is held in or on the holding portion such that the front end of the case faces a rear end of the terminal connecting portion and the rear end of the case faces the wire connecting portion.
2. The connection terminal of claim 1 , wherein the heat storage body is held inside the holding portion.
3. The connection terminal of claim 1 , wherein the case is made of a thermally expandable material.
4. The connection terminal of claim 1 , wherein:
the holding portion is formed into a tubular shape, and
the heat storage body is provided in an internal space of the holding portion.
5. The connection terminal of claim 1 , wherein:
the holding portion includes a projecting piece projecting in a direction intersecting an arrangement direction of the terminal connecting portion and the wire connecting portion, and
the holding portion holds the heat storage body by crimping the projecting piece to an outer surface of the heat storage body.
6. The connection terminal of claim 1 , wherein:
the holding portion includes a bottom wall extending between the terminal connecting portion and the wire connecting portion and a side wall standing on the bottom wall, and
the heat storage body includes an engaging portion to be engaged with the side wall.
7. The connection terminal of claim 1 , wherein the terminal connecting portion includes a base portion and a locking portion, the locking portion being positioned between the base portion and the wire connecting portion, and a diameter of an outer peripheral surface of locking portion being greater than a diameter of an outer peripheral surface of the base portion.
8. A connector, comprising:
the connection terminal of claim 1 ; and
a connector housing for holding the connection terminal.
