摘要： PROBLEM TO BE SOLVED: To provide an inexpensive cable protecting tube for repair, with which rigidity is secured, without making an outside diameter size to be larger than an established cable protecting tube. SOLUTION: The cable protecting tube for repair 10 is provided with a first split tube part 12 and a second split tube part 14. A guide part 16 is fitted to the inner face of the first split tube part 12. When the outer face of the guide part 16 and the inner face of the second split tube part 14 are bonded and the first split tube part 12 and the second split tube part 14 are bonded, the cable protecting tube for repair 10 in an integrated tube type is formed. Since a center angle of an arc-like cross-sectional shape of the second split tube part 14 is 180 degrees or larger, a bonding part 17 of the first split tube part 12 and the second split tube part 14 will not come above the cable protecting tube for repair 10. Since the outside diameter of the cable protecting tube for repair 10 will not become large, there is less restrictions in the installation space and an existing joint etc. can be used. Since the guide part 16 covers the bonding part 17 and it reinforces the first split tube part 12, rigidity is improved. The guide part 16 covers the bonding part 17 and the bonding part 17 comes below the cable protecting tube for repair 10. Thus, cut-off performance is given, and only the small number of components is required. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：为了提供廉价的用于修理的电缆保护管，其刚性被确保，而不使外径尺寸大于已建立的电缆保护管。解决方案：用于修理的电缆保护管10设置有第一分裂管部分12和第二分裂管部分14.引导部分16装配到第一分裂管部分12的内表面。当外部接合引导部16的表面和第二分割管部14的内表面，并且接合第一分割管部12和第二分割管部14，形成集成管型的修理用电缆保护管10 。由于第二分割管部14的弧形截面形状的中心角为180度以上，所以第一分割管部12和第二分割管部14的接合部17不会在电缆的上方用于修理的保护管10.由于用于修理的电缆保护管10的外径不会变大，所以在安装空间中的限制较少，并且可以使用现有的接头等。由于引导部16覆盖接合部17并且加强第一分割管部12，所以刚性提高。引导部16覆盖接合部17，接合部17位于电缆保护管的下方进行修理10.因此，具有切断性能，仅需要少量的部件。版权所有（C）2007，JPO＆INPIT
