The invention discloses a cable splice box suitable for communication
engineering, which comprises a lower box body, a rotating shaft, an upper box body, a clip head, a slot, a connection port, a sub-connection port, a cable, a hoop, an anti-skid pad, a first Primary tension spring, fixing frame, connecting shaft, snap ring, fixing card, fixing groove, connecting nut, sleeve, hanging ring, fixing rod, hook, second tension spring,
throat hoop, waterproof tape, conductive foam and Cable
barrel shielding. The invention uses the fixing rod, the hoop, the first pull-back spring and the second pull-back spring to play a good buffering role when the cable is pulled by it, and solves the problem that the cable joint is easy to loosen under other pulls of the hand ; and through the sealing between the lower box body and the upper box body and the function of waterproof tape, the cable joint can be prevented from being affected by
moisture; at the same time, the external interference
signal can be blocked in time through the conductive foam and the shielding layer of the cable
barrel, which is the
cable line. normal communication guarantee.
