Abstract

An electrical connection box for a vehicle has a casing and at least one bus bar within the casing to which in use a high nominal maximum voltage of not less than about 14V and not more than about 200V is applied. On the upper wall of the casing, there is a relay accommodation structure an upstanding walls defining first and second recesses at which positive and negative terminals of the relay are inserted in use. The recesses are partitioned from each other by one upstanding wall which has an upper edge at which an inclined groove is provided for carrying away water by gravity. Thereby risk of leak currents is minimized.

Claims

1. An electrical connection boxcomprising:

a casing having an upper wall;

at least one bus bar which is mounted within said casing and to which in use a nominal maximum voltage of not less than about 14V and not more than about 200V is applied; and

on said upper wall of said casing, a relay accommodation structure adapted to receive in use at least one electrical relay and comprising upstanding walls defining at least a first recess at which a positive terminal of the relay is to be inserted and a second recess at which a negative terminal of the relay is to be inserted, said first and second recesses being partitioned from each other by one of said upstanding walls which has an upper edge at which an inclined groove is provided for carrying away water by gravity.

2. An electrical connection box according to claim 1, wherein said nominal maximum voltage is about 42V.

3. A vehicle comprising:

an electrical power source providing a nominal maximum voltage of not less than about 14V and not more than about 200V;

an electrical connection box comprising;

a casing having an upper wall;

at least one bus bar which is mounted within said casing and to which in use a nominal maximum voltage of not less than about 14V and not more than about 200V is applied, said electrical power source being electrically connected to said bus bar; and

on said upper wall of said casing, a relay accommodation structure adapted to receive in use at least one electrical relay and comprising upstanding walls defining at least a first recess at which a positive terminal of the relay is to be inserted and a second recess at which a negative terminal of the relay is to be inserted, said first and second recesses being partitioned from each other by one of said upstanding walls which has an upper edge at which an inclined groove is provided for carrying away water by gravity; and

an electrical relay mounted at said relay accommodation structure and comprising positive and negative terminals respectively received in said first and second recesses.

4. A vehicle according to claim 3, wherein said nominal maximum voltage is about 42V.
