Description

The present invention relates to a magnet switch cover and a magnet switch protection structure, and in particular, improves the mounting workability, prevents partial occurrence of an uncovered part, and unintentionally disengages or rotates after mounting. It relates to a device that has been devised to prevent such a situation.

  For example, a magnet switch is attached to a starter for starting the engine. A main terminal and a connecting terminal are respectively led to one end face of this type of magnet switch. These main terminals and connecting terminals are fixed by a mold cap. A battery cable is connected to the main terminal via a plate-like terminal. The main terminal, the terminal and the end of the battery cable are covered with a cover.

  An example of the configuration of the magnet switch and the vicinity thereof will be described with reference to FIGS. First, as shown in FIGS. 14 and 15, there is a starter 201 for starting the engine. A magnet switch 203 is attached to the starter 201. A main terminal 205 and a connecting terminal 207 are led out from one end face of the magnet switch 203, respectively. The main terminal 205 and the connecting terminal 207 are fixed by a mold cap 209. As shown in FIG. 17, a battery cable 213 is connected to the main terminal 205 via a terminal 211. The end of the battery cable 213, that is, the main terminal 205 is covered with a magnet switch cover 215. This is because a voltage is constantly applied to the main terminal 205, so that it is necessary to prevent water splashing and inadvertent contact with the main terminal 205.

Further, as shown in FIGS. 14 and 17, the mold cap 209 is provided with insulating ribs 217 for partitioning between the main terminal 205 and the connecting terminal 207.

For example, Patent Document 1 and Patent Document 2 disclose the configuration of this type of magnet switch.
