Description
Technical field:
The present invention relates to electricity field, particularly relate to cable connecting device, particularly a kind of metal-rubber shielded joint.
Background technology:
Electrical equipment is connected by joint with cable.In prior art, partial cables uses Copper Foil, aluminium foil or copper wire to carry out
Shielding, and cable connector or occurs to be easily destroyed cable shield during vibrations in installation process, additionally, at dismounting cable
Time, also it is easily destroyed screen layer.
Summary of the invention:
The technical problem to be solved is to provide a kind of metal-rubber shielded joint, described this metal-rubber shielding
In joint prior art to be solved, cable connector is easily destroyed the technical problem of cable shield.
This metal-rubber shielded joint of the present invention, including a fittings body, described fittings body is by a tubulose structure
Part is constituted, and wherein, the end of described tubular element is provided with external screw thread, and the middle part of tubular element is provided with convex annular and puts into effect
Rank, tubular element is provided with a locking nut by described external screw thread, is provided with a sealing member in tubular element, described
Sealing member in a tubular form, be provided with a conductive rubber ring in sealing member, described conductive rubber ring is coaxial with sealing member.
Further, argent powder is distributed in described conductive rubber ring.
Further, the excircle of described conductive rubber ring is provided with circumferential groove.
The operation principle of the present invention is: shielded cable, through locking nut, sealing member, conductive rubber ring and fittings body, is led
Electricity rubber ring can prevent fittings body, the sealing member mechanical damage to cable shield, meanwhile, conductive rubber ring and locking nut,
Sealing member and fittings body conduction, constitute shielding environment.
The present invention compares with prior art, and its effect is positive and obvious.The present invention arranges conduction in fittings body
Rubber ring, can prevent fittings body, the sealing member mechanical damage to cable shield, and meanwhile, conductive rubber ring can tightly wrap
The screen layer of cable, plays the effect of conductive shields；Install, remove and with repeatable operation, and can not damage the screen layer of cable.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of metal-rubber shielded joint of the present invention.
Detailed description of the invention:
Embodiment 1:
As it is shown in figure 1, a kind of metal-rubber shielded joint of the present invention, including a fittings body 1, described fittings body 1 is by one
Individual tubular element is constituted, and wherein, the end of described tubular element is provided with external screw thread, and the middle part of tubular element is provided with annular
Protruding step, tubular element is provided with a locking nut 2 by described external screw thread, is provided with a sealing in tubular element
Part 3, described sealing member 3 in a tubular form, is provided with a conductive rubber ring 4 in sealing member 3, described conductive rubber ring 4 is with close
Sealing 3 is coaxial.
Further, argent powder is distributed in described conductive rubber ring 4.
Further, the excircle of described conductive rubber ring 4 is provided with circumferential groove.
The operation principle of the present embodiment is: shielded cable is through locking nut 2, sealing member 3, conductive rubber ring 4 and joint
Body 1, excircle has circumferential groove conductive rubber ring 4 can provide buffering, prevents fittings body 1, sealing member 3 to cable shield
Mechanical damage, meanwhile, conductive rubber ring 4 conducts electricity with locking nut 2, sealing member 3 and fittings body 1, constitute shielding environment.
