Description
Technical field
Patent of the present invention relates to electric connector field, provides a kind of plug with retaining mechanism, i.e. self-locking plug adapter.
Background technology
The electric connector product that is threaded, for product after guaranteeing docking still can guarantee reliable mechanical connection under severe vibration, shock environment, needs double thread locking.Present field of connectors, the locking thread method that butt end is commonly used is as follows: 1, on coupling nut, beat the fuse hole, after connection, by coupling nut is fastened to fuse, prevent thread looseness; 2, auger shell pit on screw thread, after being threaded, tighten determine screw check 3, by auxiliary body, increase the frictional force that coupling nut rotates, realize locking, but this is locking and unreliable.
There is complex operation in use in above method, take up room or the shortcoming such as reliable not.
People urgently wish to obtain the good self-locking plug adapter of a kind of technique effect so that plug with without auxiliary operation, just can realize locking after socket docks, in easy and simple to handle, guarantee that plug is connected reliably with socket.
The patent of invention content
The order of patent of the present invention is to provide a kind of self-locking plug adapter, after making this self-locking plug adapter and socket docking, even just can guarantee under violent shock and vibration, to have reliable mechanical connection without other auxiliary operations, plug is without beating the aid in treatment such as fuse, operation, safeguard more convenient.And when plug and socket release, also without auxiliary operation, as normally unscrewing screw thread, operate and get final product, electric connector can unclamp in first release again, and is convenient and swift.
It is constructed as follows self-locking plug adapter of the present invention: interior coupling nut 1, outer coupling nut 2, elastomeric pad 3, ripple spring 4, lock washer 5, spacing back-up ring 6, doubling-up jump ring 7, plug casing 8, contact 9 and insulator assembly 10.
Describedly for the interior coupling nut 1 that docks with the external screw thread of respective socket, be provided with internal thread, realize that the contact 9 that is electrically connected and the insulator assembly 10 that plays insulating effect are arranged on the inside of plug casing 8, interior coupling nut 1, outer coupling nut 2, elastomeric pad 3, ripple spring 4, lock washer 5, spacing back-up ring 6, doubling-up jump ring 7 and plug casing 8 form the retaining mechanism that screw thread loosens of realizing of described self-locking plug adapter by the interaction of each part.
Common J599 III series plug (meeting GJB599A-1993) adopts thread connecting mode, has that quick connection, 100% anti-oblique cutting, good EMI/RFI shield effectiveness, contact can be fetched and delivered, three advantages such as anti-.Patent of the present invention, on the basis of having inherited J599 III series plug advantage, is continued to use the same-interface size, adopts newly-designed retaining mechanism double thread locking; Plug with must manual operation after socket is connected, that is: External Force Acting could release, can guarantee that electric connector has reliable mechanical connection under high vibration environment.And plug is without beating the aid in treatment such as fuse, operation, safeguard more convenient.The coupling nut assembly adopts the composite material manufacture, with same housing J599 III series plug product, compares, and in the profile size constancy, quality is lighter.
Described interior coupling nut 1 is the circulus of an end diameter less than other end diameter, and interior coupling nut 1 is provided with hook groove 101, groove 102, sawtooth 11 and helicitic texture; Described sawtooth 11 is positioned at ring one end that coupling nut 1 diameter is little, hook groove 101 is positioned at coupling nut 1 one ends identical with sawtooth 11, and be positioned at coupling nut 1 outside, groove 102 is positioned at the outer middle side part of coupling nut 1, and described helicitic texture is positioned at coupling nut 1 inboard;
Described outer coupling nut 2 is provided with protruding pin 201, convex tendon 202 and annular groove 203; The described convex tendon 202 that coordinates with groove 102 is positioned at outer coupling nut 2 middle inside, and the protruding pin 201 that coordinates with hook groove 101 is positioned at outer coupling nut 2 inboards, and described annular groove 203 is positioned at outer coupling nut 2 one end inboards;
Described spacing back-up ring 6 is arranged in the annular groove 203 of outer coupling nut 2, simultaneously, is enclosed within outer shroud one end that interior coupling nut 1 diameter is little;
Described interior coupling nut 1 is connected with protruding pin 201 by groove 102 and convex tendon 202, hook groove 101 with outer coupling nut 2;
Described lock washer 5 is circulus, and an end of lock washer 5 is provided with sawtooth 11, and inboard is provided with protruding key 501;
Described plug casing 8 is circulus, and the arranged outside of plug casing 8 has recessed keyway 801;
Described lock washer 5 is connected by sawtooth 11 with interior coupling nut 1, and lock washer 5 is connected with recessed keyway 801 by protruding key 501 with plug casing 8; Described lock washer 5 is provided with elastomeric pad 3 with plug casing 8 junctions and guarantees that plug is under locking state, the ripple spring 4 that interior coupling nut 1 and the sawtooth that loosens packing ring 5 fit tightly;
The effect doubling-up jump ring 7 that internal coupling nut plays axial restraint is positioned at outer shroud one end that coupling nut 1 diameter is little, and it is fixed in the annular groove of plug casing.
It is right-angle side that described interior coupling nut 1 is a side with the zigzag fashion that loosens packing ring 5, and a side is hypotenuse.
The screw thread locking mechanism locking state, that is: remove outer coupling nut, referring to Fig. 3, this locking device mainly is comprised of interior coupling nut 1, elastomeric pad 3, ripple spring 4, lock washer 5, doubling-up jump ring 7 and plug casing 8, interior coupling nut band 1 has internal thread, after with externally threaded socket, tightening, lock washer 5 and interior coupling nut 1 the two end face at mutual overlap joint have sawtooth 11, under the elastic force effect of ripple spring 4 and elastomeric pad 3, the tooth of lock washer 5 and interior coupling nut 1 is intermeshing, prevents from relatively rotating.Simultaneously, the protruding key 501 of lock washer coordinates with the recessed keyway 801 of plug casing 8, and the two can not relatively rotate.So locking state has guaranteed coupling nut and can not freely rotate.Therefore after screw-threaded coupling, retaining mechanism has prevented that coupling nut internal thread and the externally threaded screw thread pair of socket from getting loose, thereby plays locking effect, realizes locking.
When screw thread need to get loose, the nut component that is rotatably connected, outer coupling nut 2 rotates counterclockwise simultaneously and moves axially along interior coupling nut 1 hook groove 102, thereby drive spacing back-up ring 6, moves axially.Under the axial thrust effect of spacing back-up ring 6,3 compressions of ripple spring 4 and elastomeric pad, thus intermeshing tooth between lock washer 5 and interior coupling nut 1 is separated, realize release.
During locking state, the convex tendon 202 of outer coupling nut 2 is embedded in the inside of the groove 102 of interior coupling nut 1, and therefore outer coupling nut 2 can freely not rotate with respect to interior coupling nut 1, that is, retaining mechanism is release voluntarily not.Only between thinking under the effect of external force moment of torsion by convex tendon 202 and groove 102, producing the inside and outside coupling nut of strain just can relatively rotate.
Even under released state, namely as previously described, outer coupling nut 2 drives spacing back-up ring 6 and moves axially, and pushes intermeshing sawtooth between lock washer 5 and interior coupling nut 1 open, and plug still has higher reliable lock.Reason is, between lock washer 5 and spacing back-up ring 6, has larger frictional force, even if the effect of this frictional force makes under released state, coupling nut rotates still needs larger torque.
The self-locking plug adapter that patent of the present invention provides can guarantee that electric connector has reliable machinery, electrical connection under violent shock and vibration, and plug is without beating the aid in treatment such as fuse, operation, safeguards conveniently, has huge economic worth and social value.
