Connector of the present utility model, adopt the sheet spacer that insulator and connector shell are fixed, the very thin thickness of sheet spacer, so only need just the sheet spacer can be installed on the connector shell offering the more shallow rectangle location notch of the degree of depth on the connector shell, therefore, also can adopt the sheet spacer to carry out the fixed insulation body even the wall thickness of connector shell is thin.Adopt the structure of sheet spacer to fix insulator,, therefore can guarantee the consistency of product quality because the manufacturing of location notch and sheet spacer can reach the requirement of machining accuracy easily.In addition, 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.
Also have, 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.
