The novel pressure-resistant optical cable or electric cable or photoelectric hybrid cable according to any embodiment is characterized in that the pressure-resistant belt 2 is a stainless steel belt or a chrome-plated steel belt.
In the utility model, when the optical cable or the electric cable or the optical/electrical hybrid cable is pressed, the pressing head 23 corresponding to the pressed part or the part near the pressed part moves inwards along the pressure reduction groove 52, the reinforcement main body 51 on both sides of the pressing head 23 moves towards both sides, so that the other two pressing heads 23 on both sides of the pressing head 23 extrude outwards, and the space between the pressure resistant belt base bands 21 on both sides of the pressing head 23 and the reinforcement main body 51 is released, so that the inner loose tube 3 or the inner insulating layer 6 is not pressed; the plurality of pressure resistant belts 2 on the pressure resistant belt 2 also enhances the torsion resistance of the optical cable or the electric cable or the photoelectric hybrid cable; because the space is arranged between the pressure resistant belt 2 and the reinforcement main body 51, heat generated by the operation of the lead 7 in the cable or the photoelectric hybrid cable can be dissipated through the space, the thermal aging time of the outer protective layer 1 of the optical cable and the reinforcement main body 51 is prolonged, the service life of the cable is prolonged, and higher current can pass through the lead 7 through better heat dissipation; in addition, the pressure resistance belt base belt 21, the supporting part 22 and the extrusion head 23 are made of metal materials, so that the heat conduction effect is good, and the heat generated by the operation of the lead 7 can be conducted into the pressure reduction groove 52 through the pressure resistance belt base belt 21, the supporting part 22 and the extrusion head 23 and is diffused into the external air through the pressure reduction groove 52.
The utility model solves the problem that the supporting part is easy to bend when the pressure is large; the pressure borne by the supporting component buffers the pressure through the size change of each pressure-resistant groove, so as to achieve the effect of protecting the supporting component from bending; and the structure is simple and the manufacture is convenient.
