Abstract

Provided is an electrical junction box having a highly versatile novel structure such that external wires can be connected thereto from multiple directions. An electrical junction box includes cases in which a circuit member is disposed, and the cases include an external-wire fastening part in which a connection part provided on the circuit member is exposed, and to which a connection terminal provided at an end of an external wire is to be fastened and fixed. The external-wire fastening part includes a fastener that is used to fasten and fix the connection terminal to the connection part, and the external-wire fastening part has a plurality of fastening points whose normals that extend from the central axis of the fastener to a peripheral wall of the cases have the same length, the plurality of fastening points being oriented in different directions.

Claims

1. An electrical junction box that has a case in which a circuit member is disposed, the case being provided with at least one external-wire fastening part in which a connection part provided on the circuit member is exposed, and to which a connection terminal provided at an end of an external wire is to be fastened and fixed,

wherein each of the at least one external-wire fastening part has a fastener that is used to fasten and fix the connection terminal to the connection part,

each of the at least one external-wire fastening part has a plurality of fastening points, and each of the plurality of fastening points are normal to each other and extend from a central axis of the fastener to a peripheral wall of the case have the same length, the plurality of fastening points being oriented in different directions, and

a plurality of the connection terminals oriented in different directions are to be fastened and fixed to the at least one external-wire fastening part.

2. The electrical junction box according to claim 1,

wherein the external-wire fastening part is provided in a corner of the case, the corner is defined by a first side wall and a second side wall that constitute the peripheral wall of the case, and two fastening points are provided as a result of the normals respectively extending from the central axis of the fastener to the first side wall and the second side wall being equal to each other.

3. The electrical junction box according to claim 1, wherein the external-wire fastening part includes a partition protrusion that is located between the plurality of fastening points, and protrudes upward from the connection part, so as to define a pair of slots, each of the slots being orthogonal to each other.

4. The electrical junction box according to claim 2, wherein the external-wire fastening part includes a partition protrusion that is located between the plurality of fastening points, and protrudes upward from the connection part, so as to define a pair of slots, each of the slots being orthogonal to each other.
