Description

  The present invention relates to a cable unit installed on an indoor wall surface.

  Conventionally, various types of cable units having an extension function by incorporating a winding mechanism have been developed for power cables (outlets). And the thing of various forms, such as the type (for example, patent document 1 and patent document 2) which is built in a wall beforehand, and the type (for example, patent document 3 and patent document 4) which is installed in an indoor wall surface after retrofitting, is also the form. Has been developed.

  Also, cable units having an extension function by incorporating a winding mechanism have been developed for television cables and LAN cables other than the power cable.

Japanese Utility Model Publication No. 62-144084 JP 62-22379 A JP-A-11-97102 Japanese Patent Laid-Open No. 62-17968 JP 2009-94039 A JP 2006-66158 A Registered Utility Model No. 3045771

  However, although all of these cable units described in the patent document have an extension function, there is a problem that the cable is disconnected when an excessive tensile force is applied to the cable. Especially for the cable unit described in Patent Documents 1 to 3 and 6 and the cable unit described in Patent Document 4 among the outlets installed on the wall surface indoors as a retrofit. However, since it is directly applied to the cable and the terminal portion, there is a problem that disconnection is likely to occur. In addition, the cord repeater described in Patent Document 7 has a structure in which the terminal of the target LAN cable is locked to the jack by a claw (locking member). There is a problem that disconnection and disconnection / breakage of terminals are likely to occur.

In addition, since the cable unit described in Patent Document 5 is detached from the insertion plug when a tensile force is applied, the cable is less likely to be disconnected than the cable unit described above. There is a problem that when the plug is removed from the plug, there is a possibility of damaging the plug itself or the outlet into which the plug is inserted.
Furthermore, the cable unit described in Patent Document 5 has a structure in which the terminal is locked to the jack, although the terminal is an outlet so that it can be easily detached from the plug even when a tensile force is applied.

  In particular, when the cable is a television cable or a LAN cable, there are many cases in which work cannot be performed without the use of a craftsman having specialized skills. And among them, the LAN cable is not only composed of 8 thin cables, but the arrangement order of the cables is also decided, so in order to ensure communication quality, we specialize in terminal termination work. There is a problem that craftsmen with special skills and dedicated tools are essential, and it takes more time for replacement and repair.

Recently, as a result of intensive studies, the present inventors have provided a housing member and a cable storage member, so that only a simple operation of replacing the cable storage member even when a cable disconnection or a terminal claw breakage occurs. Led to the development of a cable unit that can repair and replace cables.
Further, by providing a locking mechanism in such a cable unit, the connection between the indoor wiring and the cable in the cable housing member can be made more reliable, and further, by making the locking mechanism a specific structure, We have developed a cable unit that can effectively prevent disconnection of the cable in the cable housing member and disconnection / breakage of the terminal even when the cable is pulled more than necessary, such as when the cable is pulled out. .
