However, each of the above-mentioned patent documents has the following technical problems.
Specifically, the technique described in Patent Document 1 can fix the connector, but cannot protect the wire harness under the connector neck (the wire harness in the vicinity of the connector housing pulled out from the connector). It has a technical problem.
Therefore, when wiring a wire harness using the connector of the type of Patent Document 1, the wire harness at the lower neck portion may be damaged by interference with a metal edge or a burr of the vehicle body. In particular, when the wire harness is extended from the connector, there is a high possibility that the wire harness interferes with and damages the metal edge or burr of the vehicle body. The case where the wire harness is extended from the connector refers to the case where the wire harness branch line 120b is pulled out in the X direction shown in the drawing as an example in FIG.

On the other hand, if the connector cover of patent document 2 is used, the wire harness of the connector neck lower part mentioned above can be protected.

The connector protection cover is attached to the connector by fitting the fitting portion to the connector attachment portion, and the upper surface portion and the side surface portion are configured to protect the electric wire drawn from the connector. ing.
With the above configuration, the connector protective cover of the present invention can be mounted regardless of the shape and dimensions of the connector itself as long as it is a connector having the above-described mounting portion, and can protect the electric wire drawn from the connector.
That is, according to the present invention, a highly versatile connector protective cover can be obtained.

Further, it is desirable that a rod-like portion extending in a direction substantially parallel to the side surface portion is formed at the tip of the side surface portion.
Thus, by providing the bar-shaped part, the wiring direction of the electric wire drawn out from the connector can be regulated (the bar-shaped part can prevent the electric wire from bulging and breaking), and the work of wiring the electric wire can be reduced. it can.
Further, the rod-like portion is put (inserted) into a trunk line (for example, a trunk line of a wire harness routed in the vehicle) where the electric wires drawn out from the connector merge, and the rod-like portion is taped together with the trunk line. By fixing, the connector to which the connector protective cover is attached can be fixed to the trunk line.
Thus, by using the connector cover of the present invention, it is possible to protect the electric wire drawn from the connector and fix the connector to the trunk line with a single component.
Further, according to the present invention, there is no need to use a component that occupies a space such as a connector receiving component (for example, the clamp 100 shown in FIG. 4), and the connector can be fixed to the wire harness in a space-saving manner.

Moreover, it is preferable that the attachment part provided in the connector has a projecting lock part, and the fitting part is formed with a lock hole shaped to fit the lock part.
Then, by inserting the protruding lock portion of the mounting portion of the connector into the lock hole of the connector protective cover and attaching the connector protective cover to the connector, the connector protective cover is unlikely to be detached from the connector. Thus, the connector cover is prevented from falling off from the connector.
