Title: BSP WATERPROOF CABLE JOINT
Abstract:
A BSP (British Standard Pipe) waterproof cable joint comprises a fixed head (1), a fastener (5), a plastic main body (3) and a seal ring (2). The fixed head is provided with an internal thread. The fastener is provided with an internal thread. The plastic main body includes a seal area provided with a seal tooth (30) and a connection area. The seal area is provided with an external thread matched with the internal thread of the fixed head and the connection area is provided with an external thread matched with the internal thread of the fastener. The seal ring is radially suitable for being mounted in the plastic main body and being bonded with the inner wall of the seal area. The inner wall of the seal tooth extends towards the central axial direction to form at least one barb (31); and an annular step (20) matched with the barb is formed in a position where the outer wall of the seal ring and the barb are bonded. When the BSP waterproof cable joint is in the fastening process, the fixed head is tightened and the seal tooth is compressed to contract to the central axis, so that the barb can be just matched with the annular step of the seal ring and the seal ring is tightly compressed, thereby increasing the fastening force exerted on a cable passing through the cable joint and enhancing the sealing and waterproofing effects.
