Abstract

A waterproof protective cover including an identifying portion which is capable of identifying a predetermined position in a chamber for receiving a connection part of electric wires in an insertion direction. The identifying portion is formed outside a side wall of either upper casing member or lower casing member. By taking advantage of the identifying portion, the connection part of electric wires can be positioned at a predetermined position in a chamber defined by the upper and lower casing members. Moreover, the chamber for receiving the connection part of electric wires has no change in a capacity thereof, so that a filling amount of the sealant is not reduced; therefore, sealing performance can be improved.

Claims

1. A waterproof protective cover for a connection portion of an electric wire comprising:

an upper casing member and a lower casing member, each of said casing members having a pair of side walls aligning with a direction of travel of the electric wire, cooperable to define a chamber, said chamber including a receiving position for receiving the connection portion of the electric wire, said receiving position being provided at a preselected position in the chamber along the direction of travel of the electric wire, one of said side walls of said lower member including an inner side wall and an outer side wall spaced from said inner wall; and

a reinforcing rib provided on said inner side wall, an upper portion of said reinforcing rib defining a receiving position location marker for identifying said receiving position of the connection portion of the electric wire, said receiving position location marker being aligned with the preselected position of the receiving position on a line generally perpendicular to the direction of travel of the electric wire.

2. The waterproof protective cover according to claim 1, wherein said receiving position location marker has a color different from a color of other parts of the cover.

3. The waterproof protective cover according to claim 1, wherein said chamber is filled with an insulative sealant where the receiving position receives the connection portion of the electric wire.

4. The waterproof protective cover according to claim 1, wherein protrusions project from at one of said side walls of the upper casing member, and said outer side wall of said lower casing member defines an engagement wall having notches to engage said protrusions.

5. A waterproof protective cover for a connection portion of an electric wire comprising:

an upper casing member and a lower casing member, each casing member having a pair of side walls aligning with a direction of travel of the electric wire, cooperable to define a chamber, said chamber including a receiving position for receiving a connection portion of the electric wire, said receiving position being provided at a preselected position in the chamber along the direction of travel of the electric wire; and

a hinge pivotably connecting said upper casing member and said lower casing member between two adjoining ones of said side walls, said hinge including a gap, said gap defining a receiving position location marker for identifying said receiving position of the connection portion of the electric wire, said gap being aligned with the preselected position of the receiving position on a line generally perpendicular to the direction of travel of the electric wire.
