Description
Technical field
The present invention relates to a kind of anti-shake 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 needs with coupling nut pin connector and socket connector to be fixedly attached to after socket connector plugs together, and prevents from 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; between coupling nut and pin connector housing or socket connector housing without any anti-loose structure; 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 the performance reduction through regular meeting; or even pin connector and socket connector separated by shake, influences the normal operation of Circuits System.
Summary of the invention
The purpose of this invention is to provide a kind of anti-shake 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 achieving the above object, the present invention adopts following technical scheme: a kind of anti-shake connector, comprise connector shell, the connector shell outside is rotatably equipped with the coupling nut with internal thread, be provided with between described coupling nut and the connector shell and prevent the loosening locking gear of coupling nut reversing, described locking gear comprises in turn along axis and press-fits doubling-up jump ring between coupling nut and connector shell, elasticity ratchet ring and baffle plate, the corresponding cover in the outside of described doubling-up jump ring is equipped with the L-shaped back-up ring of axial cross section, this back-up ring only revolves with the doubling-up jump ring and cooperates, the interference of described doubling-up jump ring is threaded onto on the connector shell, described doubling-up jump ring only revolves with the elasticity ratchet ring and cooperates, be integrally formed with the elastic cantilever that along the circumferential direction extends on the described elasticity ratchet ring outer ring, the end that overhangs of described 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 described 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; The outer peripheral face of described connector shell is provided with shoulder, and the inner peripheral surface of coupling nut is provided with the ring platform of annular, is pressed with anti-backlash between described ring platform and the shoulder.
Described anti-backlash is the butterfly spring.
Described 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.
Described 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.
The outside conduction of described connector shell is connected with arch ground connection spring.
The outer peripheral face of described coupling nut is provided with the tread plate that extends vertically.
Described coupling nut circumferentially be provided with anti-skidding annular groove.
Anti-shake 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, guarantee this connector connection stability, and then guaranteed the reliability that circuit connects.In use, after pin connector and socket connector are pegged graft, the nut that is rotatably connected is fixed together pin connector and socket connector, because the rotation direction of the rotation direction of double wedge and ratchet one way engagement and doubling-up jump ring is opposite, when therefore being rotated in the forward coupling nut, coupling nut drives the doubling-up jump ring, elasticity ratchet ring and pad move together, very little of rotatory force of this moment, it is motionless that the doubling-up jump ring is held the connector shell maintenance tightly when the reverse rotation coupling nut, and then make elasticity ratchet ring and pad also keep motionless, and coupling nut must could rotate by the elastic cantilever that the downward compression elasticity ratchet ring of ratchet circumferencial direction extends will rotate the time, therefore the power of this moment is very big, has also just effectively played locking effect because this power is big.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 screws, coupling nut drives 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.In addition, between the ring platform of the shoulder of connector shell and coupling nut, be pressed with anti-backlash, anti-backlash make connector shell and coupling nut keep one mutually away from movement tendency, after this movement tendency can make pin connector and socket connector is connected, locking effect has been played in gap between the screw thread that elimination cooperatively interacts equally.
Adopt the butterfly spring can reduce the axial length of this connector as anti-backlash.
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 mutually and be connected, and carries out ground connection by 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.
Also be provided with on coupling nut 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.
