Abstract
A plastic claw self-locking type tail accessory of a circular electric connector comprises a screw cap, a tail shell, a plastic claw, a cylindrical pin and a clamping ring, wherein the clamping ring is arranged in the screw cap to clamp the tail shell, so that the tail shell, the screw cap and the plastic claw arranged in the screw cap are assembled and fixed. The self-locking anti-loosening device has the advantages of convenience and rapidness in assembly, high reliability, no need of riveting in connection, durability, repeated friction, no phenomenon of plating falling and slag falling, good stability, and capability of uniformly generating elastic deformation according to a preset track to achieve self-locking and loosening prevention.
Description
Technical field
The utility model belongs to technical field of electric connectors, especially belongs to a kind of plastics claw self-locking type afterbody annex of round electric connector.
Background technology
Round electric connector afterbody annex is installed, and mainly adopts nut and afterbody shell mechanical connection on the annex, reaches the purpose that annex is installed after screwing by nut screw thread and connector tailing screw flight then.The mechanical connection of nut and connector afterbody shell wherein, if can rotate mutually, connector uses in the environment of vibration, nut easily takes place rotate the phenomenon that gets loose.The self-locking type annex is adopted in present technical development, makes the rotation of annex nut need overcome certain resistance by the self-locking part, thereby reaches anti-loose purpose.
Existing conventional self-locking type annex is made up of rotary nut, afterbody shell, stay, rivet etc.During rotating screw cap, because stay and nut adopt rivet to be integral, stay is along with rotation, recessed tooth interlock on double wedge on the stay and the afterbody shell, if will continue rotary nut, owing to relatively rotate, recessed toe joint on stay upper raised teeth and the afterbody shell touches, and makes stay produce compression, when deflection acquires a certain degree, recessed tooth on stay upper raised teeth and the afterbody shell is thrown off, thereby enter previous interlocking pattern, so repeatedly, make the rotation of nut must overcome the power that convex tooth piece is thrown off mutually, this power is the power that swivel nut gets loose and must overcome, thereby reaches anti-loose effect.
Have characteristics such as convenient, fast, reliability height, but also have following defective:
1, the metal stay with need riveted joint being connected of nut, be easy to crack, defective such as play.
2, be the intermetallic repeated friction between metal stay and the stop tooth, be easy to cause plating exfoliation and fall the slag phenomenon, become frequent failure cause.
3, the riveted joint of metal stay and nut need be finished before the afterbody shell is packed nut into, adopt pressure to revolve riveting when nut forever is connected with the stop shell, must before the part plating, finish, and when adopting component to electroplate, be easy to generate electroplate insufficient, coating pore, adhesion poor, be capped part and do not have inherent shortcomings such as coating.
Summary of the invention
The purpose of this utility model is the problem that exists at above technical scheme, proposes a kind of plastics claw self-locking type afterbody annex of round electric connector.
The utility model has adopted the plastics claw as locking member, replaces traditional metal stay.Penetrate the nut location hole by straight pin set on the plastics claw and fix, be designed to a ring annular groove in the nut simultaneously, the axial Bit Shift of restriction plastics claw makes the plastics claw remain in the nut.Get and replaced the frame mode that stay and nut is connected as one with rivet, the afterbody shell penetrates from the nut tail end, compresses the plastics claw, the plastics claw is in nut and the afterbody shell circumferential clearance reliably, and keeps certain elastic forepressure.By the collar that the is provided with nut of packing into, block the afterbody shell at last, realize that afterbody shell and nut assembling fix.
Adopt the beneficial effect of technique scheme:
(1) it is convenient that plastics claw self-locking annex of the present utility model is compared the conventional structure assembling, do not need to turn over the riveter preface, this structure can guarantee that the plastics claw does not produce and swings in nut simultaneously, can elastic deformation evenly take place according to desired trajectory.
(2) owing to adopt the high-toughness wear-resistant plastics, the plastics claw is excellent spring not only, simultaneously because friction parts is respectively plastics and metal material, can produce the coating damage and fall slag through long-term use, has solved greatest drawback in the original structure.
Description of drawings
Fig. 1 a, Fig. 1 b are the plastics claw self-locking annex principal section and the side cross section view of the utility model round electric connector;
Fig. 2 a, Fig. 2 b are plastics claw front view of the present utility model and side cross section view.
Among the figure: 1-nut, 2-afterbody shell, 3-plastics claw, 4-cylindrical pins, 5-collar, 6-nut cannelure, 7-dowel hole, 8-plastics claw double wedge, the recessed tooth of 9-shell.
Embodiment
The plastics claw self-locking annex of round electric connector described in the utility model now contrasts accompanying drawing its execution mode is described in further detail: its composition structure mainly comprises nut 1, afterbody shell 2, plastics claw 3 and the cylindrical pins 4 that is connected as a single entity with plastics claw 3 and plastics claw double wedge 8, collar 5, nut cannelure 6, dowel hole 7, the recessed tooth 9 of shell; Adopt the high-toughness wear-resistant plastic production to become the good plastics claw 3 of elasticity, a straight pin 4 is established on the top of plastics claw 3, on nut 1 with matching, be provided with dowel hole 7, be provided with an annular groove 6 in the nut, restriction plastics claw 3 is axially displaced, be installed in by two plastics claws 3 in the groove of annular, each plastics claw 3 symmetric position is provided with inside double wedge 8, and with shell 2 in recessed gear ring 9 interlock mutually of establishing, by the collar 5 that the is provided with nut 1 of packing into, block afterbody shell 2, realize that the plastics claw assembling in afterbody shell and nut and the nut is fixing.Because it is anti-loose that the double wedge 8 of plastics claw and recessed gear ring 9 Elastic Contact of shell of metal material reach self-locking, uses for a long time through repeated friction, can not produce the coating damage and fall slag, overcome the greatest drawback in the original structure.
