Abstract

A fuse unit attachment structure includes a fuse bracket to be mounted on a battery directly attaching type fuse unit and a bracket connecting member for connecting the fuse bracket to a battery. The fuse bracket has a unit supporting portion to support the battery directly attaching type fuse unit such that so as to be movable in a direction perpendicular to a lateral surface of the battery and a connecting member engaging portion to be engaged with the bracket connecting member so as to be movable in a direction along the lateral surface of the battery.

Claims

1. A fuse unit attachment structure comprising a fuse bracket configured to be mounted on a battery directly attaching type fuse unit, the battery directly attaching type fuse unit configured to be connected to a battery terminal to be fastened to a battery post of a battery such that a portion of the battery directly attaching type fuse unit is disposed on a side of a lateral surface of the battery, and a bracket connecting member configured to connect the fuse bracket to the battery,

wherein the fuse bracket comprises a unit supporting portion configured to support the battery directly attaching type fuse unit such that the battery directly attaching type fuse unit is movable in a direction perpendicular to the lateral surface of the battery and a connecting member engaging portion configured to engage with the bracket connecting member so as to be movable in a direction along the lateral surface of the battery, and

wherein the bracket connecting member comprises a guide plate portion configured to engage with the connecting member engaging portion to support the fuse bracket such that the fuse bracket is movable in the direction along the lateral surface of the battery and a battery connection portion configured to engage with an engaging portion provided on a top surface of the battery around a post arranging section of the battery on which the battery post is arranged such that a movement of the battery connection portion in a direction along the top surface of the battery is restricted.

2. The fuse unit attachment structure according to claims 1, wherein the engaging portion on the top surface of the battery is an existing mounting hole provided on the top surface of the battery to mount a post cover that covers an upper portion of the battery post.

3. The fuse unit attachment structure according to claim 1, wherein the unit supporting portion comprises a pair of first guide grooves with which respective sides of a terminal connection section of the battery directly attaching type fuse unit to be connected to the battery terminal are engaged such that the respective sides of the terminal connection section are slidable in the direction perpendicular to the lateral surface of the battery, and

wherein the connecting member engaging portion comprises a pair of second guide grooves with which the guide plate portion of the bracket connecting member provided in a protruding manner is engaged such that the guide plate portion is slidable in the direction along the lateral surface of the battery.
