Its main function is to connect and fix the cable, guarantees its high waterproof performance and fire behaviour function of requirement simultaneously. Thereby effectively forming long-term stable effective protection for the cable and the equipment.
The existing electromagnetic compatibility cable joint adopts a one-way protection mode, only a locking cap is used for pressing a rubber piece to enable the rubber piece to tightly hold a cable, but water molecules or oil attached to the cable easily permeate to a cable shielding layer along with the movement of the cable in the movement process of the cable to cause the reduction of the shielding effect, the failure or the short circuit.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model provides a bi-polar protection metal electromagnetic compatibility cable joint realizes the protection to the cable conductor shielding layer through the inside and outside structure of bi-polar protection of equipment simultaneously. Therefore, the problem that water molecules or oil attached to the cable possibly permeate to the cable shielding layer along with the movement of the cable to cause the reduction of the shielding effect, the failure or the short circuit in the running process of the electric control of the motor is effectively solved.
The technical scheme of the utility model is that: the double-end protection metal electromagnetic compatibility cable joint comprises a metal body and a metal cap, wherein external threads are processed on the outer surface of one side, facing the metal cap, of the metal body, internal threads are processed on the inner surface of the metal cap, and a rubber inner core is arranged at the end part, facing the metal cap, of the metal body; when the internal thread of the metal cap is matched and screwed with the external thread of the metal body, the rubber inner core inside is pressed to deform and tightly contact with the cable inserted into the rubber inner core;
a shielding ring is arranged in the metal body and can be in contact with the shielding layer on the outer surface of the cable;
an annular boss extending towards the center direction is arranged in the metal body, the annular boss is positioned on one side, away from the metal cap, of the shielding ring, and the height of the annular boss is lower than that of the shielding ring;
the annular boss is provided with flat annular rubber circle in the shielding ring one side of keeping away from, the centre bore diameter of flat annular rubber circle is less than the cable conductor diameter, the centre bore of flat annular rubber circle can be passed to the cable conductor.
Further, the diameter of the central hole of the flat annular rubber ring is four fifths to five sixths of the diameter of the cable. When guaranteeing that the cable conductor can pass the centre bore of flat cyclic annular rubber circle, can guarantee again that when the cable conductor passes flat, the parcel that flat cyclic annular rubber circle can be abundant is outside at the shielding layer, stops hydrone or oil completely and connects inside along the cable conductor infiltration, causes the shielding effect reduction of shielding layer, inefficacy or short circuit phenomenon.
Furthermore, a nylon protective sleeve is arranged on the inner side of the end part of one side, far away from the metal cap, of the metal body. Can effectual protection cable conductor, prevent that the cable conductor from producing the friction with sharp limit of metal when crooked, wearing out the cable conductor insulating layer.
Furthermore, an O-shaped sealing ring is arranged at a sealing corner where the outer surface of the metal body is connected with external equipment. The sealing effect is ensured.
The utility model has the advantages that: this device is an efficient bi-polar protection locking device, and rubber inner core and flat cyclic annular rubber circle in the device can effectually prevent that the motor from taking the power of dragging of cable in the operation process to lead to water on cable surface layer or oil follow the cable to get into the joint inside to lead to the problem of shielding effect reduction, inefficacy or short circuit of shielding layer.
Adopt the nylon protective sheath as terminal protection, the effect lies in can effectual protection cable conductor, prevents that the cable conductor from producing the friction with sharp limit of metal in the bending, rubs the cable conductor insulating layer.
This device still greatly reduced customer's cost of labor still greatly reduced the risk of shield layer department intaking or oil on improving safety in utilization.
