Description
Technical Field
The invention relates to the technical field of pigtails, in particular to an armored long-service-life pigtail.
Background
The pigtail is mainly applied to an air gun in a high-pressure air gun seismic source system on a marine exploration ship, and because the air gun can generate very large high-pressure vibration bubbles when being triggered, the pigtail can receive strong impact force from seawater under the action of the seawater, and the pigtail can break at the joint of a metal part and water discharge sealing plastic under the action of frequent external impact force, so that water inflow leakage phenomenon occurs, and normal operation of the ship is seriously influenced. In order to solve the problem that the pigtail breaks and faults and prolong the service life of the pigtail, an armored long-life pigtail is developed.
Disclosure of Invention
The invention aims to solve the problems, and designs an armored long-life pigtail which comprises a metal part, a plastic part and a cable and is characterized by further comprising a folding preventer, a metal protective shell and a lock catch, wherein the plastic part is arranged on one side of the metal part, one end of the plastic part is connected with the cable, the folding preventer is wrapped on the outer side of the cable, one end of the folding preventer is a horn mouth, the horn mouth is connected with the plastic part through a thread locking glue, the metal protective shell is arranged on the outer side of the plastic part, one end of the metal protective shell is provided with a folding edge I, the folding edge I is hooked on the horn mouth, the other end of the metal protective shell is provided with threads, the metal protective shell is in threaded connection with one end of the lock catch, the other end of the lock catch is provided with a folding edge II, and the folding edge II is hooked on the metal part.
The anti-folding device is an anti-folding spring.
The length of the horn mouth is more than 10mm.
The surfaces of the lock catches and the surfaces of the metal protective shell are respectively provided with anti-skid patterns.
The beneficial effects are that:
The metal protective shell is additionally arranged to protect the plastic part, and when external impact force acts on the pigtail line, the metal shell is utilized to resist the impact force, so that the plastic is protected from breaking faults, and meanwhile, in order to protect the joint of the tail cable and the plastic part from cracking and damaging due to frequent shaking and bending, the folding preventer is additionally arranged to protect the joint, and has high elasticity, can disperse bending force born by the cable, protects the cable and is not easy to break and crack;
2, the outer side of the cable is wrapped with an anti-folding device, the anti-folding device is an anti-folding spring, the length of the horn mouth is more than 10 mm, and the horn mouth is connected with the connecting element through the thread locking glue, so that the horn mouth is firmly connected with the connecting element and is not easy to fall off;
The design of the horn mouth can prevent the bending-prevention device from moving forwards, the first folding edge hooks the horn mouth, the bending-prevention device can be prevented from moving backwards, the lock catch is in threaded connection with the metal protective shell, and the second folding edge is hooked on the connecting element, so that the connection firmness is enhanced;
4, the anti-skid patterns increase the surface roughness of the lock catch and the metal protective shell, so that the lock catch and the metal protective shell are not easy to fall off from hands.
