Description
Technical field
The utility model relates to a kind of shielded type cable device, relates in particular to a kind of shielded type cable waterproof and clamps.
Background technology
Shielded type cable is meant the interference signal of the outside metal screen layer by the cable outside sponged, and prevents from that control signal to cable inside from producing to disturb.Or the metal screen layer of the interference that the cable internal control signal is produced by the cable outside sponge, and prevents from the outside produced to disturb.The effect of the shielded type cable connector of electromagnetic compatibility will be delivered to the interference signal on the shielded type cable layer on control cubicle or the equipment parent by metallic object exactly effectively, is delivered to big ground by ground connection and plays shielding action.
Electromagnetic compatibility shielding cable connector in the market generally comprises metal joint bolt, joint core body, circle nut, seal cartridge, O RunddichtringO.Track bolt comprises and is provided with externally threaded front end spiral shell head and rear end spiral shell head, front end spiral shell head root is provided with a sealing ring, the joint core body is set in the rear end spiral shell head of track bolt, the afterbody of joint core body is a circle stay, the annular seal lining is set in the stay, the circle spiro cap is loaded on outside joint core body, the seal cartridge, on the rear end spiral shell head that is arranged at track bolt that spins.On clamping core body leading portion and track bolt socket place, add during use and put an O type circle, with shielded type cable penetrate round nut successively, afterbody is arranged with the joint core body of seal cartridge and the track bolt that front end spiral shell head root is provided with the O RunddichtringO, then the cable leading portion is peelled off crust and expose the screen conductor, again with screen conductor anti-package on joint core body and sheathed thereon O RunddichtringO, the joint core body that will be surrounded by screen is then filled in the track bolt, covers and screw round nut again.Elastic force by O type circle compresses contacting of screen conductor and metal joint bolt.
There is following defective in this kind shielded joint body: 1, can only use on the screen that cuts off of cable end.2, on the core body between O type circle and the joint key gap less, the core body that has wrapped screen is difficult to fill in the metal key, maybe can only wrap into shielded conductor partly, influence reaches best shield effectiveness.3, the corresponding screen conductor of thick cable line of big specification is also thick, harder relatively, and the reflexed difficulty relatively of coming also is not easy quickly its anti-package to be not easy to operator's installation on core body.Cooperating between existing in addition shielding connector core body and the joint key can not spline, and core body can be along with rotation when causing nut to screw, and influence can make cable also follow rotation.Existing shielding connector also exist the seal cartridge that is contained in the core body can in the locking process, produce firmly outside squeeze-out phenomenon.
Summary of the invention
Technical problem to be solved in the utility model be to provide that a kind of shield effectiveness is good, the shielded type cable waterproof of simple installation, dependable performance clamps.
For solving the problems of the technologies described above, electromagnetic compatibility shielding cable waterproof of the present utility model is clamped and is comprised the metal joint bolt, the joint core body, nut, seal cartridge, sealing ring, track bolt comprises and is provided with externally threaded front end spiral shell head and rear end spiral shell head, joint core body canned paragraph is socketed in the track bolt, and axial limiting is in the limited step of track bolt inwall, joint core body locking section is provided with a circle sheet stay, seal cartridge is arranged in the stay, clamping is provided with the metallic shield snap ring between track bolt and joint core body, the shielding snap ring comprises the screen contact-segment of extending vertically that internal diameter is less, the elasticity tapered section, and the canned paragraph of fixed clamp between track bolt and joint core body, screen contact-segment and elasticity tapered section are made up of a circle sheet metal that extends out from shielding snap ring canned paragraph, and shielding snap ring and track bolt keep electrically contacting.
Be preferably in joint core body canned paragraph and be provided with axially extended location convex tendon, the corresponding location matches of track bolt be provided with axial contract groove, the tail end of the canned paragraph of shielding snap ring be provided with axial notch and be arranged at the joint core body on location convex tendon front end scarf mutually.Stretch formula folding hook in the afterbody of the stay of joint core body can be provided with, be complementary with the groove of the outer diametric plane of seal cartridge afterbody.
Unscrew the clamp nut of rear end of electromagnetic compatibility shielding cable waterproof during use, penetrate front end then and peel off the outer cable that protects insulating barrier, exposed screen.Make shielding snap ring and exposed screen form effectively and electrically contact, screw nut, thus clamping cables, lock sealing lining,
Adopted the electromagnetic compatibility shielding cable waterproof of the present utility model of said structure to clamp, because the ingenious design of shielding snap ring, clamping can be easy and accomplish stable electrically contacting between cable shield and the metal joint bolt reliably.Thereby greatly reduce operation complexity, alleviated labour intensity, improved operating efficiency.
Joint core body and track bolt and the teeth groove location structure of shielding between the snap ring have then overcome effectively and easily produce relative rotation between track bolt, joint core body and the shielding snap ring and influence the problem of job stability.
Stretch in joint core body stay aft mounted that formula folding hook has solved effectively then that seal cartridge in the long-term use is extruded and the problem that lost efficacy.
