Description

  The present invention relates to a seal member provided on an end seal member of a cable connection portion closure and a cable connection portion closure.

  Cable connection closures are provided at the connection part of cables buried in the ground, and those that require airtightness and those that are provided at the connection part of overhead cables, have a drip-proof property that is lower in level than airtightness. There is something to request. As a sealing member for a cable connection closure that requires drip-proof properties, a sealing member made of soft rubber that has a split at one place in the circumferential direction and becomes annular when the split surface is abutted has been proposed ( For example, see Patent Document 1). This seal member has a groove which penetrates in the axial direction to form a through hole when the split surface is abutted at the center, and the split surface is abutted while holding the cable in one of the grooves. The inner peripheral surface and the outer peripheral surface of the cable are in close contact and sealed.

A cable connection closure provided at a connection portion of an aerial cable is required to be inexpensive while satisfying the drip-proof property. However, since the seal member described in Patent Document 1 uses a soft rubber material that requires special characteristics, the material is expensive and the seal part cannot be manufactured as a single unit, which increases the manufacturing cost. It is a factor.
