Claims (8)

  1. A wiring box having a box-shaped body with an opening, It consists of a string-like cable escape prevention member that is attached to a mounting part provided on the main body of the wiring box, and is installed so as to cross the opening, thereby preventing the cable housed in the main body from coming out. A wiring box device characterized in that interference is avoided by deforming the anti-flyout member installed in the opening of the main body, thereby enabling the cable to be housed and arranged inside the main body through the opening.
  2. The wiring box device according to claim 1, characterized in that the anti-ejection member is extendable in the longitudinal direction.
  3. The wiring box device according to claim 1 or 2, characterized in that the mounting portion is positioned close to the peripheral wall forming the opening of the main body and protrudes from the bottom side of the main body toward the opening.
  4. The wiring box device according to claim 1 or 2, characterized in that the wiring box is provided with a lid that covers the opening so as to conceal both the mounting portion and the anti-ejection member when the anti-ejection member is attached.
  5. The wiring box device according to claim 1 or 2, characterized in that the wiring box is fixed to a ceiling wall or the like , with the opening of the main body facing downward, and the cable fall prevention member is capable of supporting the cable and preventing the cable placed inside the main body from falling.
  6. A wiring box having a box-shaped body with an opening, The peripheral wall forming the opening of the main body has multiple mounting points on the opening side for attaching a string-like anti-ejection member so that it crosses the opening and the anti-ejection member is positioned there. A wiring box device characterized in that the tip of the mounting portion has an anti-pull-out portion formed thereon to prevent the hooked anti-pull-out member from coming loose.
  7. The wiring box device according to claim 6, characterized in that the pull-out prevention portion is located outward from the opening-side end of the peripheral wall forming the opening of the main body.
  8. The wiring box device according to claim 6, characterized in that the mounting portion is entirely located inside the main body.

Description

This invention relates to a wiring box device used for fixing equipment such as surveillance cameras and housing the cables of said equipment inside. One example of the wiring box device described above is the one disclosed in Patent Document 1, which includes a fixing section for securing a surveillance camera and a wiring storage space capable of accommodating the connection portion of the cable connected to the surveillance camera and the excess length of the cable. The cables housed in the wiring enclosure tended to sag or bulge out due to their natural curl, making it difficult to close the cover of the enclosure. In particular, when the wiring box was installed with the opening facing downwards, opening the cover would cause the cable bundles inside to sag, putting stress on the connections and hindering maintenance. Furthermore, Patent Document 2 describes a branch box body 4 consisting of a box-shaped base plate 2 and a lid member 3 covering the opening of the base plate 2. In this body, a protrusion-restricting member 52, made of a bent metal piece, is attached to the base plate 2 to prevent the inter-unit connection cord 24 housed within the base plate 2 from protruding. However, the necessary electrical equipment is arranged within the base plate 2, limiting the space available for the excess length of the inter-unit connection cord 24. Therefore, the protrusion-restricting member 52 only prevents the inter-unit connection cord 24 from protruding when it is partially positioned within this limited space. Therefore, when the proportion of the opening to the front-view area of the wiring box (opening occupancy ratio) is large, that is, when the majority of the front-view area of the wiring box is an opening, it is necessary to cover the excess length of the cables housed within the entire opening with a cable-out prevention member. Thus, the cable-out prevention member 52 disclosed in Patent Document 2 cannot address this issue.
