A kind of bidentate fast insert-pull locking cylindrical connector
Technical field
The invention belongs to technical field of electric connectors, specifically relate to a kind of bidentate fast insert-pull locking cylindrical connector.
Background technology
Cylindrical connector uses comparatively extensive on Electronic equipment panel, and be generally that socket is fixed on device panel, plug is free end, by plugging together and being separated between plug with socket, loop is produced and switches on and off.Along with miniaturization and the simple operation of electronic equipment, mostly require that cylindrical connector has fast insert-pull locking function.
Current use more fast insert-pull locking cylindrical connector be bayonet type fast insert-pull locking cylindrical connector.The fast insert-pull retaining mechanism of this cylindrical connector mainly contains two parts composition: one is the swivel nut with pin on plug, and two is helicla flutes corresponding with pin in jack housing.Plug and socket need to screw swivel nut when plugging together, and realize plugging together and locking of plug and socket by the slip of pin in jack housing helicla flute.The weak point of this fast insert-pull retaining mechanism is adopted to be: one is machining spiral groove in jack housing and detection difficult; Two is that swivel nut needs to drive plug to move forward when screwing and plugs together with socket, and the frictional force between pin and helicla flute is comparatively large, and swivel nut screws difficulty, causes plug to dock difficulty with socket.
Summary of the invention
The object of the invention is to the deficiency existed for bayonet type fast insert-pull locking cylindrical connector, provide a kind of bidentate fast insert-pull locking cylindrical connector.
The object of the invention is to be achieved by following technical solution.

Described hole pedestal 10 is provided with anti-rotation boss 1001.
Assembling of the present invention is further described below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, during plug assembling of the present invention, first load in pin pedestal 2 by contact pin 8, be enclosed within by front casing 1 on pin pedestal 2, contact pin 8, pin pedestal 2 and front casing 1 are adhesively fixed by blend compounds stick; Then 12 springs 3 are respectively charged in the spacing keyway 202 of pin pedestal 2, and the tail end of back-up ring 4 from pin pedestal 2 is inserted in; Again head shell 7 being loaded from pin pedestal 2 tail end, as shown in Figure 10, Figure 11, when loading head shell 7, the sign groove B703 on a shell 7 being alignd with the sign groove A102 on front casing 1; Rear casing 6 is loaded from pin pedestal 2 tail end, as shown in Figure 11, Figure 12, after said fitting during shell 6, the first teeth groove 601 on rear casing 6 is aimed at the limiting tooth 701 on head shell 7; Finally collar 5 is loaded from rear casing 6 tail end, and be stuck in the collar groove 201 on pin pedestal 2 as shown in Figure 6, complete the assembling of whole plug.
As shown in Figure 3, Figure 4, during socket assembling of the present invention, first that jack 12 is front loaded from hole pedestal 10, then loaded from hole pedestal 10 tail end by seat shell 9, seat shell 9, hole pedestal 10 and jack 12 are adhesively fixed together by blend compounds stick; Finally nut 11 is screwed on the screw thread of a shell 9, the assembling of whole socket can be completed.
Application of the present invention is further described below in conjunction with accompanying drawing.
Socket in use, is first fixedly mounted on Electronic equipment panel plate, then is docked with socket by plug by a kind of bidentate fast insert-pull locking cylindrical connector of the present invention.As shown in Fig. 5 to Figure 13, when plug docks with socket, first the sign groove B703 on head shell 7 in plug is indicated groove 904 with first on the sign groove A102 on front casing 1 and seat shell 9 to align, three feather keys 702 on head shell 7 are alignd with interior three guide key grooves 902 of socket seat shell 9, then directly plug is shifted onto position forward, now the anti-rotation groove 1-1 of front casing 1 front end is meshed with the anti-rotation boss 1001 of seat pedestal 10 front end, prevents pin pedestal 2 and hole pedestal 10 from producing relative rotation; Limiting tooth 701 on head shell 7 is deviate from from the first teeth groove 601 rear casing 6, limiting tooth 701 rear end face on head shell 7 higher than the teeth groove boss 602 on rear casing 6, but lower than the front end face 604 of rear casing 6; Feather key 702 on head shell 7 is arranged in the cannelure 901 of socket seat shell 9; Spring 3 is compressed; Finally head shell 7 is turned clockwise 30 °, make the sign groove B703 on a shell 7 indicate groove 905 with second on seat shell 9 to aim at, back shell 7 of loosing one's grip automatically is drawn back under the effect of spring 3 spring force, the feather key 702 on a shell 7 is made to be arranged in inspection hole 903 on a shell 9, limiting tooth 701 on head shell 7 is stuck in the second teeth groove 603 on rear casing 6, thus realizes fast and reliable locking between plug and socket.
As shown in Fig. 5, Figure 11, Figure 13, when plug and socket need to be separated, first by head shell 7 to pressing down, the feather key 702 on a shell 7 is made to be arranged in the cannelure 901 of socket seat shell 9, then head shell 7 is rotated counterclockwise 30 °, make the sign groove B703 on a shell 7 indicate groove 904 with first on seat shell 9 to aim at, thus realize the unblock between plug and socket; Subsequently plug is directly pulled out backward, plug can be realized and pull out with the fast direct of socket and be separated.
