Abstract
The utility model provides an electric connector locking anti vibration device, this locking anti vibration device includes electric connector swivel nut, wave washer, moves ratchet, quiet ratchet and electric connector shell, moves the ratchet and fixes in electric connector swivel nut termination hole, and quiet ratchet is fixed on the connector shell and simultaneously with moving the ratchet interlock contact, and the wave washer is installed between electric connector swivel nut and the moving ratchet, move, quiet ratchet spiral-closure direction ratchet angle is less than the direction ratchet angle of pine, through the ratchet structure cooperation of the different angle ratchets of moving, quiet ratchet, makes the electric connector when butt joint use, and the connecting thread keeps the spiral-closure all the time and is difficult for the trend that the pine takes off to improve electric connector locking anti vibration performance.
Description
One, technical field
The utility model relates to a kind of locking antivibration device of electric connector, belongs to technical field of electric connectors.
Two, background technology
The electric connector product that regular screw threads connect is when docking connection; usually adopt plug swivel nut screw thread to reach purpose of connecting with cooperating of socket screw thread; the electric connector of this mode in use; usually can be owing to external force (vibration condition etc.) causes thread looseness; thereby influence the reliability that connector connects; cause to contact problems such as unreliable, cause the user normally to use.
Three, summary of the invention
The purpose of this utility model is that the problem at above-mentioned connector connected mode exists provides a kind of convenient and practical electric connector locking antivibration device.
The locking antivibration device of electric connector of the present utility model is made up of electric connector swivel nut, wave washer, moving ratchet, quiet ratchet and electrical connector housing, moving ratchet wherein is fixed in the electric connector swivel nut stomidium, quiet ratchet is fixed on the connector shell and contacts with moving ratchet interlock simultaneously, wave washer is installed between electric connector swivel nut and the moving ratchet, and described dynamic and static ratchet screws direction ratchet angle less than the direction ratchet angle that gets loose.
What vital part of the present utility model moved ratchet, the employing of quiet ratchet is the plastics ratchet structures, and the plastics ratchet adopts, and engineering plastics Mould Machining wear-resisting, good toughness is shaped.
After the utility model adopted the said structure scheme, working (machining) efficiency height, high conformity can improve electric connector antivibration anti-loosening property.
Four, description of drawings
Fig. 1 is the locking antivibration apparatus structure of a utility model electric connector view;
Among the figure, 1-electric connector swivel nut, 2-wave washer, the moving ratchet of 3-, the quiet ratchet of 4-, 5-electrical connector housing.
Fig. 2 is the expanded view of ratchet ratchet;
A-screws direction ratchet angle, the b-direction ratchet angle that gets loose.
Five, embodiment
As shown in Figure 1, the locking antivibration device of electric connector of the present utility model is made up of electric connector swivel nut 1, wave washer 2, moving ratchet 3, quiet ratchet 4 and electrical connector housing 5, and moving ratchet 3 wherein, quiet ratchet 4 are vital parts of this mechanism.Moving ratchet 3 is fixed in electric connector swivel nut 1 stomidium, quiet ratchet 4 is fixed on the connector shell 5 and contacts with moving ratchet 3 interlocks in the swivel nut, wave washer 2 is installed in the space between swivel nut 1 and the moving ratchet 3, for the tight interlock of moving ratchet, quiet ratchet 4 provides axial compressive force, their axial freedom limits by shell.No matter electric connector screws the screw thread screw thread that still gets loose, dynamic and static ratchet all can misplace and skid like this, and the skid size of required external force of dislocation is to be determined by the angle of ratchet on the ratchet.Therefore, screw the ratchet angle b of direction (clockwise) ratchet angle a as long as make less than the direction that gets loose (counterclockwise), just can make butt joint moment less than the moment that gets loose, the normal pressure that the size of concrete ratchet angle and wave washer distortion back produce can be determined according to the requirement of vibration condition, so that make product when vibration, the screw thread that the electrical connector plug swivel nut cooperates with socket moves towards clockwise (promptly screwing) direction, thereby reaches the purpose of locking antivibration.
What vital part of the present utility model moved ratchet 3,4 employings of quiet ratchet is the plastics ratchets, and the plastics ratchet adopts, and engineering plastics Mould Machining wear-resisting, good toughness is shaped working (machining) efficiency, high conformity.
