Service plug
A service plug includes: a base member in which a circuit terminal adapted to be connected to an electric circuit is provided and an open hole is formed in such a manner as to face the circuit terminal; a plug body comprising a short-circuit terminal adapted to be inserted into the circuit terminal; and a restricting member provided in the vicinity of the open hole of the base member for restricting movement of the plug body in a direction which intersects an inserting direction of the short-circuit terminal.
1. An attaching construction of a service plug, comprising:
a base member having an open hole that accommodates therein a circuit terminal adapted to be connected to an electric circuit; and
a plug body including a short-circuit terminal adapted to be inserted into the open hole, such that the short-circuit terminal is electrically connected to the circuit terminal;
wherein the base member is provided with a restricting member disposed in the vicinity of the open hole for restricting movement of the plug body in a direction which intersects an inserting direction of the short-circuit terminal, and a guide member for guiding the plug body in the inserting direction, and
wherein the restricting member projects in a height direction of the base member in such a manner as to be higher than the guide member, and
wherein the guide member is a groove formed on the base member.
2. The attaching construction of the service plug as set forth in claim 1 , wherein
the base member is provided with the guide member on an opposite side of the restricting member across the open hole and on a circuit terminal side of the open hole.
3. The attaching construction of the service plug as set forth in claim 2 , wherein
the electric circuit includes a vehicle battery,
the vehicle battery is stored at a lower portion of a floor panel lying under a seat cushion, and
the base member is disposed in a service hole portion in the floor panel in such a state that the open hole is oriented towards a lower surface of the seat cushion.
4. The attaching construction of the service plug as set forth in claim 3 , wherein
the open hole has a cylindrical shape which projects from a surface of the base member, a circumferential wall portion of the base member having the same height as that of the cylindrical portion of the open hole and is provided along a circumference of the open hole,
the restricting member is formed contiguously to the circumferential wall portion in such a manner as to extend higher in the height direction, and
the groove is formed on an inner wall of the circumferential wall portion in such a manner as to extend in the height direction so that a boss portion of the plug body is slidably fitted therein.
5. The attaching construction of the service plug as set forth in claim 4 , wherein
the restricting member has a curved surface having a shape that matches an external shape of the plug body, and
the restricting member restricts movement of the plug body in a plane to which the plug body is inserted from a direction which is parallel to the lower surface of the seat cushion and allows the plug body to rotate along the curved surface of the restricting member in the plane to thereby allow the boss portion to be fitted in the groove.
6. The attaching construction of the service plug as set forth in claim 5 , wherein
a lever is provided rotatably on the plug body, and
the lever includes a cam mechanism for causing the plug body to move along the guide member so that the short-circuit terminal is inserted into the open hole in response to rotation of the lever which is rotated in such a state that the plug body is positioned by the restricting member and the guide member.
7. An attaching construction of a service plug, comprising:
a base member having an open hole that accommodates therein a circuit terminal adapted to be connected to an electric circuit; and
a plug body including a short-circuit terminal adapted to be inserted into the open hole, such that the short-circuit terminal is electrically connected to the circuit terminal;
wherein the base member is provided with a restricting member disposed in the vicinity of the open hole for restricting movement of the plug body in a direction which intersects an inserting direction of the short-circuit terminal, and a guide member for guiding the plug body in the inserting direction,
wherein the restricting member projects in a height direction of the base member in such a manner as to be higher than the guide member, and
wherein the open hole has a cylindrical shape which projects from a surface of the base member, a circumferential wall portion of the base member having the same height as that of the cylindrical portion of the open hole and is provided along a circumference of the open hole,
the restricting member is formed contiguously to the circumferential wall portion in such a manner as to extend higher in the height direction, and
the guide member is a groove formed on an inner wall of the circumferential wall portion in such a manner as to extend in the height direction so that a boss portion of the plug body is slidably fitted therein.
8. The attaching construction of the service plug as set forth in claim 7 , wherein
the restricting member has a curved surface having a shape that matches an external shape of the plug body, and
the restricting member restricts movement of the plug body in a plane to which the plug body is inserted from a direction which is parallel to the lower surface of the seat cushion and allows the plug body to rotate along the curved surface of the restricting member in the plane to thereby allow the boss portion to be fitted in the groove.
9. The attaching construction of the service plug as set forth in claim 8 , wherein
a lever is provided rotatably on the plug body, and
the lever includes a cam mechanism for causing the plug body to move along the guide member so that the short-circuit terminal is inserted into the open hole in response to rotation of the lever which is rotated in such a state that the plug body is positioned by the restricting member and the guide member.
10. The attaching construction of the service plug as set forth in claim 7 , wherein
the base member is provided with the guide member on an opposite side of the restricting member across the open hole and on a circuit terminal side of the open hole.
11. The attaching construction of the service plug as set forth in claim 10 , wherein
the electric circuit includes a vehicle battery,
the vehicle battery is stored at a lower portion of a floor panel lying under a seat cushion, and
the base member is disposed in a service hole portion in the floor panel in such a state that the open hole is oriented towards a lower surface of the seat cushion.
