Abstract
The invention provides a shielding termination accessory. The accessory consists of an O-shaped ring, a threaded sleeve, a tail shell, screws, a pressing ring, a top ring, a tail sleeve and a shielding mesh, wherein the O-shaped ring is arranged between the threaded sleeve and the tail shell; the threaded sleeve is arranged in a groove of the tail shell; the pressing ring is arranged at the tail end of the tail shell; the shielding mesh is uniformly distributed between the pressing ring and the tail shell; the top ring is arranged at the tail end of the pressing ring and is compressed on the bevel plane of the pressing ring; the tail sleeve is in threaded connection with the tail shell; a boss at the tail end of the tail sleeve is arranged on a step of the top ring; and the screws are uniformly distributed on the circumference of the tail sleeve and are connected with screwed holes. The shielding termination accessory of the invention realizes reliable termination of the shielding mesh by adopting clamping and screw thread structures, has the characteristics of simple structure, reliable connection, simple and convenient operation and high shielding efficiency and can be widely applied to shielding termination of a round connector as well as the structures, which need shielding termination, of other electronic parts and components.
Description
Technical field
The invention belongs to technical field of electric connectors, relate in particular to a kind of shielding termination accessory.
Background technology
The function that the cable shield host wants is to prevent that the outside electromagnetic interference signal from disturbing the signal that transmission line is carried in the cable, the signal that also prevents simultaneously the cable delivered inside disturbs miscellaneous equipment on every side, realize that good screening effectiveness must have reliable shielding end on structure to guarantee.The shielding termination accessory structure that cylindrical connector is commonly used adopts two-piece type wire clamp structure to realize, gauze screen is clamped between two wire clamps, exists inconvenient, the defectives such as connection reliability is poor, shield effectiveness difference of operation.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art, thereby the shielding termination accessory that a kind of termination is reliable, easy to operate, screening effectiveness is good is provided.
A kind of shielding termination accessory is made up of O shape circle, swivel nut, afterbody case, screw, trim ring, collar, tail cover, gauze screen; Described O shape circle is located between swivel nut and the afterbody case, and swivel nut is located in the groove of afterbody case, and trim ring is located at the tail end of afterbody case, and gauze screen is evenly distributed in the middle of trim ring and the afterbody case; Collar is located at the tail end of trim ring and is pressed on its inclined-plane; The tail cover is threaded with the afterbody case, and tail cover tail end boss is located on the step of collar, and screw is distributed on the tail cover circumference and with screwed hole and is connected.
Described swivel nut inner chamber is provided with screw thread.
Described screw is three.
Adopt the beneficial effect of technique scheme to be:
Shielding termination accessory employing clamping of the present invention and helicitic texture are realized the reliable termination to gauze screen, have characteristics simple in structure, that connection is reliable, easy and simple to handle, screening effectiveness is good, can be widely used in the shielding termination of cylindrical connector, also can be applicable to other electronic devices and components and need shield in the structure of termination.
Description of drawings
Fig. 1 is a shielding termination accessory embodiment master half sectional view of the present invention;
Among the figure: 1-O shape circle, 2-swivel nut, 3-afterbody case, 4-screw, 5-trim ring, 6-collar, 7-tail cover, 8-gauze screen.
Embodiment
The present invention is described in further detail below in conjunction with the foregoing description accompanying drawing:
A kind of shielding termination accessory is made up of O shape circle 1, swivel nut 2, afterbody case 3, screw 4, trim ring 5, collar 6, tail cover 7 and gauze screen 8, is the revolving body parts.
Fig. 1 is the main half sectional view of embodiments of the invention shielding termination accessory.Shown in the figure, O shape circle 1 is assembled between swivel nut 2 and the afterbody case 3, and this screening accessory docks back O shape circle 1 and has sealing, protection against the tide, dustproof effect with connector.Swivel nut 2 thread in inner cavity realize that this screening accessory is threaded with connector, and swivel nut 2 turns over riveting in the groove 9 of afterbody case 3, make swivel nut 2 revolve riveting and are not coming off on the afterbody case 3 and can freely rotate on afterbody case 3.Trim ring 5 is assembled in the tail end of afterbody case 3, and gauze screen 8 is evenly distributed in the middle of trim ring 5 and the afterbody case 3.Collar 6 is enclosed within the tail end of trim ring 5 and is pressed on the trim ring 5 tail end inclined-planes.Tail cover 7 and afterbody case 3 threaded engagement, tail overlaps 7 tail end boss and is pressed on the step of collar 6, and screw 4 is distributed on tail and overlaps on 7 circumference, present embodiment be three uniform, screw 4 cooperates with the screwed hole that tail overlaps on 7 circumference, prevents that tail cover 7 and afterbody case 3 threaded engagement are loosening.
During the termination gauze screen, gauze screen 8 is distributed in the middle of trim ring 5 and the afterbody case 3, tail cover 7 screws with afterbody case 3 screw threads, tail cover 7 acts on the collar 6, and active force passes to trim ring 5 by collar 6, and trim ring 5 compresses gauze screen 8 and makes its firm being fixed between trim ring 5 and the afterbody case 3, compress gauze screen 8 backs and tighten screw 4 with screwdriver, make tail overlap 7 non-loosening phenomenons, keep reliable grip, reliable screening effectiveness is provided gauze screen 8.When needs dismounting gauze screen, unscrew screw 4 earlier, unscrew tail cover 7 again, make gauze screen 8 be not pressed on the afterbody case 3 promptly detachable by trim ring 5.
Shielding termination accessory of the present invention mainly is used in the shielding termination of cylindrical connector.
Shielding termination accessory employing clamping of the present invention and helicitic texture are realized the reliable termination to gauze screen, have characteristics simple in structure, that connection is reliable, easy and simple to handle, screening effectiveness is good, can be widely used in the shielding termination of cylindrical connector, also can be applicable to other electronic devices and components and need shield in the structure of termination.
