However, the orientation and position of the buckle 517 that are employed when the cables 511 housed in the protector 501 are fixed to the protector main body 503 by means of the cable tie 509 vary depending on workers, resulting in a variation in the quality of the cables protection structure. At protector attachment locations having only a small gap due to a vehicle layout design, the orientation of the buckle 517 of the cable tie 509 needs to be restricted. To this end, for example, attachment work is carried out according to a management item that specifies a range A of placement of the buckle 517 (see
The present invention has been made in view of the above circumstances, and an object of the invention is therefore to provide a cables tying structure of a protector which facilitates standard work of placing the buckle of a cable tie within a cables housing height and enables manufacture of a high-quality cable protection structure by simple work.
The above object of the invention is attained by the following configurations:
(1) A cables tying structure of a protector comprising a main body and a lid which are combined together to form a tubular body capable of housing cables; a pair of band insertion holes which are formed through the main body so as to be arranged in a direction that crosses the cables housed; a band fastening space which is defined in the main body so as to contain one of the pair of band insertion holes and in which to place a buckle of a cable tie with its top position lower than a housing height of the cables; and a fastening space closing plate which is formed in the lid and closes the band fastening space when the lid is attached to the main body.
In the cables tying structure of protector having the configuration of item (1), a band tip portion of a cable tie is inserted through one of the pair of band insertion holes that are formed in the main body, from the side of the band fastening space that is defined on the top side of the main body. The band tip portion penetrates through the main body to its back side, and is then pulled up so as to be inserted through the other band insertion hole and return to the top side. The band tip portion, pulled up to the top side and shaped like a loop, of the cable tie surrounds the cables housed in the main body by its inner surface, and is then inserted through the buckle that is provided at the rear end of the cable tie and placed in the band fastening space, whereby the cables are tied to the main body. The cable tie that is now fixed to the main body and ties the cables is placed in the band fastening space in such a manner that the buckle is in contact with the main body with its top position lower than the housing height of the cables.
If the buckle of a cable tie were not properly placed within the band fastening space and projected upward beyond the level of the housing height of the cables, the fastening space closing plate of the lid would interfere with the buckle to disable attachment of the lid. This allows the worker to recognize that the cable tie is not applied regularly. Furthermore, any worker can set the buckle of a cable tie in place in the band fastening space. Thus, the orientation and position of the buckle in cables fixing work are standardized and a quality variation of the cables protection structure can be made small.
(2) A cables tying structure of a protector which is based on the configuration of item (1) and in which the band fastening space is formed so as to have such a size that the buckle and a fastening tip portion of a band fastening tool can be inserted into it.
Where a cable tie is fastened using a band fastening tool, the cables tying structure of a protector having the configuration of item (2) allows the worker to bring a fastening tip portion of the band fastening tool into direct contact with a space bottom surface of the band fastening space. This makes it possible to produce a high-quality cables protection structure by simpler work.
