Abstract
The utility model provides a screw thread locking mechanism for circuit connector, by packing ring (1), spring (2), direction swivel nut (4) and guide post (5) are constituteed, the both ends of electric connector plug and socket are equipped with plug insulator hole (3) and socket insulator hole (6) of device direction swivel nut and guide post, the guide post is packed into in the socket insulator hole, spring and packing ring are arranged in plug insulator hole (3) along with the direction swivel nut behind the upper end of direction swivel nut (4), this mechanism can realize the separation of circuit connector plug-in and locking process, the inconvenience that brings has avoided circuit connector both ends locking or unblock simultaneously, simultaneously can the reinforce, improve its manufacturability, use when being applicable to electric connector connection and locking.
Description
One, technical field
The utility model belongs to the circuit connector technical field.
Two, background technology
The locking mode of circuit connector has screw-threaded coupling and bayonet coupling usually, and screw-threaded coupling is simple in structure with it, reliable lock and being widely used.But be limited to the narrow and small of space, screw-threaded coupling mechanism usually is fixedly mounted on the two ends that circuit connector is plug, socket, and only can turn, can not move axially.Because of it can not move axially, cause circuit connector can only to be locked simultaneously or release at two ends when separating plugging together, when asymmetric locking in two ends or release, the situation of not parallel plug all can occur, cause " the hard left-falling stroke ", cause contact elastic failure or excessive wear.In addition, existing screw-threaded coupling mechanism adopts the required moment of torsion of form transmission locking that crosses pin, and behind the small part processing cross-drilled hole, can make its intensity lower, as firmly excessive, just causes the fracture of screw-threaded coupling mechanism easily during locking.And the screwed hole in the existing screw-threaded coupling structure is blind hole, adds the man-hour fifth wheel and gets rid of difficulty, in case there have fifth wheel not remove to be clean, will cause " stuck " during locking.Because existing screw-threaded coupling structure is used inconvenience, intensity is lower and processability of product structure is poor, an urgent demand improves the screw-threaded coupling mechanism of circuit connector.
Three, summary of the invention
The purpose of this utility model, be primarily aimed at the problem that the primary circuit connector exists with screw-threaded coupling mechanism, do not changing overall dimension and guaranteeing under the prerequisite of interchangeability, provide a kind of can be axially movable screw-threaded coupling mechanism, locking again after circuit connector can be plugged together, and extract separation after the release again, the locking at two ends or release needn't be carried out simultaneously, avoid locking simultaneously or use inconvenience that release brings, improve the intensity of screw-threaded coupling mechanism simultaneously and improve processability of product structure.
Screw-threaded coupling described in the utility model mechanism is by packing ring, spring, guiding swivel nut and lead are formed, the guiding swivel nut is a hollow cylinder, the centre is a through hole, upper end band internal thread, lead is a step axle, the middle part has external screw thread, the lower end is and the corresponding circular shaft of guiding swivel nut through hole, the two ends of electrical connector plug and socket are respectively equipped with the pin insulator hole and the socket insulator bore of device guiding swivel nut and lead, lead is packed in the socket insulator bore, spring, packing ring is installed on the upper end of guiding swivel nut, turns over rivet clasp and packs in the pin insulator hole with the guiding swivel nut back surely.
After screw-threaded coupling of the present utility model mechanism adopts such scheme, do not changing overall dimension and guaranteeing under the prerequisite of interchangeability, the process that plugs together of circuit connector is separated with the locking process, avoided the inconvenience that lock simultaneously at two ends or release brings, be user-friendly to, improved the intensity of screw-threaded coupling mechanism simultaneously and improved processability of product structure.Screw-threaded coupling of the present utility model mechanism is suitable for mass production, has stronger practical value.

Five, embodiment
Below in conjunction with above-mentioned accompanying drawing example screw-threaded coupling of the present utility model mechanism is described in further detail:
Screw-threaded coupling of the present utility model mechanism is made up of packing ring 1, spring 2, guiding swivel nut 4 and lead 5.The plug of circuit connector, socket setting are processed with pin insulator hole 3 and the socket insulator bore 6 that guiding swivel nut 4 and lead 5 are installed, simultaneously in order to improve the intensity of screw-threaded coupling mechanism, former screw rod and nut united two into one form guiding swivel nut 4, through hole is processed at swivel nut 4 centers of will leading, the upper end is processed as screwed hole, and the sectional area integrator of former two parts in back that unite two into one makes the afterbody entity sectional area of guiding swivel nut 4 become big, have intensity more than needed, can improve its manufacturability.Lead 5 is a shaft-type part, the head step is installed in the socket insulator bore 6, and by shaft shoulder location, loads onto spring 2 and packing ring 1 in the upper end of guiding swivel nut 4, and make spring 2 have certain initial compression amount, so that guiding swivel nut 4 is formed supporting role, turn over riveting at guiding swivel nut 4 oral areas then, prevent that spring 2 and packing ring 1 from coming off, be installed at last in the pin insulator hole 3, after assembling was finished, guiding swivel nut 4 can spur downwards, and its displacement is exactly the decrement of spring 2.When nature, the initial resilient support of spring 2 guiding swivel nut 4, makes guiding swivel nut 4 be in position topmost, for the guiding before plugging together is got ready.When plugging together, the lead 5 on the socket is pushing away guiding swivel nut 4, and compression spring 2 moves down until plugging together and puts in place.Plug together and tighten guiding swivel nut 4 after putting in place, can finish locking.Unscrew guiding swivel nut 4 during release earlier,, pull the plug out of the socket then until withdrawing from the screw-threaded engagement state.
