Description
Technical field
The present invention relates to a kind of shock-proof check connector, belong to technical field of electric connectors.
Background technology
The connector that is threaded comprises two kinds of pin connector and socket connectors.During use, pin connector need be fixedly attached to pin connector and socket connector with coupling nut after socket connector plugs together, and prevents in use to be separated because of reasons such as vibrations make pin connector and socket connector.Coupling nut generally all be directly and pin connector housing or socket connector housing be rotatably assorted; The anti-loose structure that between coupling nut and pin connector housing or socket connector housing, has no; Be fully realize by screw thread locking; In the stronger use occasion of vibrations; Be threaded and shaken pine and finally cause pin connector and socket connector to plug together performance reduction, or even pin connector and socket connector separated by shake, influence the normal operation of Circuits System through regular meeting.
Summary of the invention
The purpose of this invention is to provide a kind of shock-proof check connector, pin connector in vibration environment, can occur and shaken with socket connector and separate the dissatisfactory problem of anti-loosing effect in order to solve the existing connector that is threaded.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: a kind of shock-proof check connector, comprise connector shell, and the connector shell outside is rotatably equipped with coupling nut; Be provided with between said coupling nut and the connector shell and prevent the loosening locking gear of coupling nut reversing; Said locking gear comprises in order and press-fits doubling-up jump ring, elasticity ratchet ring and baffle plate between coupling nut and connector shell along axis, and the corresponding cover in the outside of said doubling-up jump ring is equipped with the L-shaped back-up ring of axial cross section, and this back-up ring only revolves with the doubling-up jump ring and cooperates; The interference of said doubling-up jump ring is threaded onto on the connector shell; Said doubling-up jump ring only revolves with the elasticity ratchet ring and cooperates, and is integrally formed with the elastic cantilever that along the circumferential direction extends on the said elasticity ratchet ring outer ring, and the end that overhangs of said elastic cantilever is provided with the radially double wedge of evagination; Be provided with the ratchet with the corresponding one way engagement of double wedge in the said coupling nut, and the rotation direction of the rotation direction of double wedge and ratchet one way engagement and doubling-up jump ring is opposite.
Said back-up ring is arranged between doubling-up jump ring and the elasticity ratchet ring, and the outer ring surface of back-up ring covers in the periphery of doubling-up jump ring.
Said doubling-up jump ring has the catch that extends vertically near the end integrated setting of elasticity ratchet ring, and this catch is plugged in the elasticity ratchet ring.
The outside conduction of said connector shell is connected with arch ground connection spring.
The outer peripheral face of said coupling nut is provided with the tread plate that extends vertically.
Said coupling nut circumferentially be provided with anti-skidding annular groove.
Shock-proof check connector of the present invention; Between coupling nut and connector shell, be provided with and prevent the loosening locking gear of coupling nut reversing; Like this; Even this connector in use is given a shock the problem that also can not occur becoming flexible, has guaranteed this connector connection stability, and then guaranteed the reliability that circuit connects.In use; After pin connector and socket connector were pegged graft, the nut that is rotatably connected was fixed together pin connector and socket connector, when being rotated in the forward coupling nut; Because the rotation direction of double wedge and ratchet one way engagement is opposite with the rotation direction of doubling-up jump ring; Coupling nut drives doubling-up jump ring, elasticity ratchet ring and pad and moves together, very little of the rotatory force of this moment, when the reverse rotation coupling nut doubling-up jump ring hold tightly with connector shell on keep motionless; And then make elasticity ratchet ring and pad also keep motionless; And coupling nut must could rotate through the elastic cantilever that the downward compression elasticity ratchet ring of ratchet circumferencial direction extends will rotate the time, and therefore the power of this moment is very big, because this power has greatly also just effectively played locking effect.Outside mask at the doubling-up jump ring is equipped with the L-shaped back-up ring of axial cross section; And this back-up ring only revolves with the doubling-up jump ring and cooperates; When coupling nut was screwed, coupling nut drove the rotation of doubling-up jump ring and makes its outer diametrically opening, because doubling-up jump ring outside mask has been adorned back-up ring; The outside anchor ring of back-up ring can stop that outside of doubling-up jump ring first circle footpath is excessive, and other circle changes less situation generation; Make each circle of doubling-up jump ring balanced, and then guaranteed the doubling-up jump ring uniformity that power is transmitted on the circumferencial direction when rotating in outer comparison radially.
The outside of connector shell conduction is connected with arch ground connection spring, and arch ground connection spring can conduct electricity pin connector after connecting and housing between the socket connector each other and be connected, and carries out ground connection through earthed circuit.
The tread plate that extends vertically is set on the outer peripheral face of coupling nut, and when the turn coupling nut, tread plate plays anti-skidding effect, is convenient to manually screw or unscrew coupling nut.
On coupling nut, also be provided with along the anti-skidding annular groove of circumferentially offering, anti-skidding annular groove can play anti-skidding effect when plug, and the connector after conveniently connecting two unplugs, and has also strengthened the aesthetic property of this connector simultaneously.
