Description

  The present invention relates to a connection structure for a protective cover that covers the outer side of a wiring body such as a tubular body or wiring that is routed along a wall surface.

  In an air conditioner, an outdoor unit and an indoor unit are connected by a refrigerant pipe to circulate the refrigerant. Generally, the refrigerant pipe is routed from the outdoor unit along the outer wall to the arrangement part of the indoor unit, Although it penetrates and is guided to an indoor unit, the refrigerant pipe routed along the outdoor and indoor wall surfaces may be covered with a protective cover.

The protective cover is constituted by a cover main body member (pipe material) that covers a general part of the refrigerant pipe and a cover joint member (pipe material holder) that connects the cover main body members to each other. Is configured to insert the end portion of the cover body member to be connected into the inside of the cover joint member (see, for example, Patent Document 1).

  In the above conventional protective cover connection structure, the cover body member is inserted inside the cover joint member, so the connection portion of the cover body member must be attached to the wall surface through the thick portion of the cover joint member. become.

  For this reason, when the refrigerant pipe arranged along the outer wall is covered with a protective cover, a gap corresponding to the thickness of the cover joint member is formed between the cover main body member and the wall surface of the protective cover. As a result, the appearance of the protective cover mounting portion deteriorates, and the cover body member floats from the wall surface, so that the support strength of the cover body member decreases.

  Therefore, the present invention provides a gap between the cover body member and the wall surface while reliably positioning the cover body member and the cover joint member in the connecting direction when the cover body member is connected using the cover joint member. It is an object of the present invention to obtain a connection structure for a protective cover that can prevent the formation of.

By doing so, the tongue-like protruding portion and the recessed portion can be overlapped with each other, so that the mounting surface of the cover body member can be brought into contact with the wall surface. Therefore, it is possible to prevent a gap from being formed between the attachment surface of the cover body member and the wall surface.

  Further, when the outer surface of the cover body member is a smooth surface having no step in the longitudinal direction, the end of the cover body member is abutted against the protrusion formed on the inner surface of the cover joint member, When the outer surface of the main body member has a bellows shape, the cover main body member can be reliably positioned in the connecting direction with respect to the cover joint member by engaging the bellows groove with the protrusion.

  According to the second aspect of the present invention, the notch recesses are formed on both side portions of the tongue-like protrusion, and therefore, when the cover body member is cut, the notch recesses and the inclination generated on the end cut surface are absorbed by the notch recesses. Since it can do, the terminal part of a cover main-body member and a cover coupling member can be connected, without making it mutually interfere.

  In addition, the notch recess allows the front end portion of the cover body member whose outer surface is in a bellows shape (the portion on the terminal cut surface side from the portion engaged with the protrusion) to ride on the cover joint member, and There is also an effect that it is possible to suppress the bottom surface of the cover main body member from floating from the wall surface.
