Abstract

A spare-fuse holding structure holds a spare fuse including a pair of terminals exposed on both sides of a fuse resin main body serving as a resin main part of the spare fuse in a resin housing chamber. The spare-fuse holding structure includes a resin guide portion configured to guide, when the spare fuse is inserted into the resin housing chamber in a manner inclined with respect to the insertion direction, the spare fuse into the resin housing chamber while changing a posture of the spare fuse in the insertion direction by coming into contact with the fuse resin main body to prevent the pair of terminals from coming into contact with resin walls forming the resin housing chamber.

First claim

What is claimed is:

1. A spare-fuse holding structure that holds a spare fuse including a pair of terminals exposed on both sides of a fuse resin main body serving as a resin main part of the spare fuse in a resin housing chamber, the spare-fuse holding structure comprising:
a resin guide portion configured to guide, when the spare fuse is inserted into the resin housing chamber in a manner inclined with respect to an insertion direction, the spare fuse into the resin housing chamber while changing a posture of the spare fuse in the insertion direction by coming into contact with the fuse resin main body to prevent the pair of terminals from coming into contact with a resin wall forming the resin housing chamber, wherein
the resin housing chamber includes a bottom surface, and
the resin guide portion includes
a pair of opposed walls, and
a portion protruding from the bottom surface of the resin housing chamber and positioned between the pair of opposed walls.

2. The spare-fuse holding structure according to claim 1 , wherein
each of the opposed walls includes an inclined surface on an inner surface of an upper end, the inclined surface being inclined to have a decreasing wall thickness toward an upper edge surface.

3. The spare-fuse holding structure according to claim 1 , wherein
the resin housing chamber includes a surrounding wall configured to surround in a rectangular shape, when the fuse resin main body has a substantially rectangular shape in section, a side outer periphery of the spare fuse, the opposed walls and short-direction walls facing each other,
the insertion-opening-side guide portion includes protruding guide pieces configured to protrude like a piece from both ends of an upper edge surface of each of the pair of opposed walls of the surrounding wall and configured to be elastically deformable toward outside of the resin housing chamber to receive the spare fuse into the resin housing chamber, and
the guide wall serves as a wall portion between both ends to which the protruding guide pieces are provided in each of the opposed walls.

4. The spare-fuse holding structure according to claim 3 , wherein
the short-direction walls of the surrounding wall each have a slit that facilitates bending and deforming of the protruding guide pieces together with the opposed walls toward the outside.

5. A spare-fuse holding structure that holds a spare fuse including a pair of terminals exposed on both sides of a fuse resin main body serving as a resin main part of the spare fuse in a resin housing chamber, the spare-fuse holding structure comprising:
a resin guide portion configured to guide, when the spare fuse is inserted into the resin housing chamber in a manner inclined with respect to an insertion direction, the spare fuse into the resin housing chamber while changing a posture of the spare fuse in the insertion direction by coming into contact with the fuse resin main body to prevent the pair of terminals from coming into contact with a resin wall forming the resin housing chamber, wherein
the resin guide portion includes
an insertion-opening-side guide portion configured to guide the spare fuse to an insertion opening of the resin housing chamber,
a guide wall configured to guide, when the spare fuse is thrust into the resin housing chamber in a manner inclined with respect to the insertion direction into the resin housing chamber, the spare fuse into the resin housing chamber while changing the posture of the spare fuse in the insertion direction by causing a lower end of the fuse resin main body to come into contact with the guide wall, and
an insertion completion positioning portion configured to position the spare fuse at an insertion completion position in the resin housing chamber by causing a lower surface of the fuss resin main body to abut on the insertion completion positioning portion.

6. The spare-fuse holding structure according to claim 5 , wherein
the guide wall includes an inclined surface on an inner surface of an upper end, the inclined surface being inclined to have a decreasing wall thickness toward an upper edge surface.

7. The spare-fuse holding structure according to claim 5 , wherein
the resin housing chamber includes a surrounding wall configured to surround in a rectangular shape, when the fuse resin main body has a substantially rectangular shape in section, a side outer periphery of the spare fuse with longitudinal-direction walls facing each other and short-direction walls facing each other,
the insertion-opening-side guide portion includes protruding guide pieces configured to protrude like a piece from both ends of an upper edge surface of each of the longitudinal-direction walls of the surrounding wall and configured to be elastically deformable toward outside of the resin housing chamber to receive the spare fuse into the resin housing chamber, and
the guide wall serves as a wall portion between both ends to which the protruding guide pieces are provided in each of the longitudinal-direction walls.

8. The spare-fuse holding structure according to claim 7 , wherein
the short-direction walls of the surrounding wall each have a slit that facilitates bending and deforming of the protruding guide pieces together with the longitudinal-direction walls toward the outside.

9. The spare-fuse holding structure according to claim 6 , wherein
the resin housing chamber includes a surrounding wall configured to surround in a rectangular shape, when the fuse resin main body has a substantially rectangular shape in section, a side outer periphery of the spare fuse with longitudinal-direction walls facing each other and short-direction walls lacing each other,
the insertion-opening-side guide portion includes protruding guide pieces configured to protrude like a piece from both ends of an upper edge surface of each of the longitudinal-direction walls of the surrounding wall and configured to be elastically deformable toward outside of the resin housing chamber to receive the spare fuse into the resin housing chamber, and
the guide wall serves as a wall portion between both ends to which the protruding guide pieces are provided in each of the longitudinal-direction walls.
