Description
Technical field
The utility model belongs to technical field of electric connectors.
Background technology
The major function of core of a cable screen is to prevent that the outside electromagnetic interference signal from disturbing the signal of transmission in the core of a cable, the signal that also prevents simultaneously the core of a cable delivered inside disturbs other cable, 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 lobe formula wire clamp structures to realize, gauze screen is clamped between two board-like wire clamps, exists defectives such as connection reliability is poor, shield effectiveness difference.
Of the present utility modelly use defective that the accessory structure that a kind of termination is reliable, screening effectiveness is good is provided at above annex.
The utility model content
A kind of round electric connector screening accessory of the utility model, its objective is and have at the shielding termination accessory structure in the background technology that connection reliability is poor, the defective of shield effectiveness difference, provide a kind of termination reliable, the round electric connector screening accessory that screening effectiveness is good.This screening accessory mainly is made up of swivel nut, circlip, afterbody shell, tail cover and screen.The internal thread of swivel nut matches with the external screw thread of electric connector tail end, swivel nut is provided with inside groove, set circlip is have breach circular, the inside groove position that is in swivel nut after the circlip compression is packed into flicks, realized that swivel nut is connected cooperation with the afterbody shell, and swivel nut can rotate on the afterbody shell, and screen is evenly distributed on the centre of tail cover and afterbody shell, and the tail cover is the tail end that is contained in the afterbody shell by threaded engagement.
Shielding termination accessory of the present utility model is mainly used in the shielding termination of round electric connector.Realize that by swivel nut internal thread and electric connector tail end external screw thread this screening accessory is threaded with connector, swivel nut is connected and fixed and can freely rotates on the afterbody shell by circlip and afterbody shell.The tail cover is assembled in the tail end of afterbody shell, and gauze screen is evenly distributed in the middle of tail cover and the afterbody shell.The tail cover cooperates with the afterbody outer casing screw, and the tail cover is pressed in gauze screen on the afterbody shell, and screw is distributed on the tail cover circumference.
During the shielding termination, gauze screen is distributed in the middle of tail cover and the afterbody shell, and the tail cover screws with the afterbody outer casing screw, compresses gauze screen and makes its firm being fixed between tail cover and the afterbody shell, and reliable screening effectiveness is provided.When needs dismounting gauze screen, unscrew the tail cover, gauze screen is not compressed by trim ring get final product.
Adopt the beneficial effect of the technical program to be: this shielding termination accessory connects reliable, and screening effectiveness is good, simple in structure.
Description of drawings
Fig. 1 is the utility model round electric connector screening accessory master half sectional view;
Among the figure: 1-swivel nut, 2-circlip, 3-afterbody shell, 4-tail cover, 5-screen.
Embodiment
The utility model is described in further detail below in conjunction with the foregoing description accompanying drawing:
A kind of shielding termination accessory of the present utility model is made up of swivel nut 1, back-up ring 2, afterbody shell 3, tail cover 4 etc., is the revolving body parts.
Fig. 1 is the main half sectional view of embodiment shielding termination accessory of the present utility model.Shown in the figure, realize that by swivel nut 1 internal thread and electric connector tail end external screw thread this screening accessory is threaded with connector, circlip 2 is circular for the band breach, after being compressed in the afterbody shell groove, the integral body swivel nut 1 of packing into, flick after circlip 2 arrives swivel nut 1 inside groove position, realization swivel nut 1 is connected cooperation and can rotates on afterbody shell 3 with afterbody shell 3.Screen 5 is evenly distributed in the middle of tail cover 4 and the afterbody shell 3, and tail cover 4 is assembled in the tail end of afterbody shell 3 by threaded engagement.
During termination screen 5, screen 5 is distributed in the middle of tail cover 4 and the afterbody shell 3, and tail cover 4 screws with afterbody shell 3 screw threads, compresses screen 5 and makes its firm being fixed between tail cover 4 and the afterbody shell 3 that reliable screening effectiveness is provided.When needs dismounting screen 5, unscrew tail cover 4, make screen 5 be not pressed on the afterbody shell 3 promptly detachable by tail cover 4.
Shielding termination accessory of the present utility model adopts the helicitic texture realization to the reliable termination of gauze screen, have characteristics simple in structure, that connection is reliable, easy and simple to handle, shield effectiveness is good, can be widely used in the shielding termination of cylindrical connector, also can be applicable in the structure that other electronic devices and components need to shield termination.
