Embodiment Construction

[0022] Embodiment 1 of the nut screw mechanism of the present invention, as Figure 1-4 As shown, it includes a screw nut 11 and a screw 12 threaded with the screw nut 11. The rear end of the screw nut 11 is equipped with a hand wheel 13, and the hand wheel 13 is put on the screw nut 11 from the rear end of the screw nut 11 and passed through the circlip 14. Fixed on the screw nut 11, the screw nut 11 and the hand wheel 13 are keyed together, and the screw nut 11 can be driven to rotate by turning the hand wheel 13, so the hand wheel 13 forms the holding part of the screw nut 11; the screw nut 11 is on the hand wheel 13 is coaxially equipped with an inner sleeve 15, the inner sleeve 15 is assembled on the nut 11 through a bearing 16, and its rear portion has a reduced diameter section with a reduced outer diameter, which makes the inner sleeve 15 A stepped surface facing the rear is formed on the outer wall, and there is a mounting hole 17 on the reduced-diameter section. The ...

Abstract

The invention relates to the field of electric connectors, particularly to an anti-looseness type nut screw mechanism and an electric connector using same. A nut screw mechanism comprises a nut and a screw. A controlling part which is used for controlling is arranged on the rear portion of the nut; an inner sleeve is arranged in the front of the controlling part on the nut; a fastening cover sleeves the inner sleeve and matches with the inner sleeve along a front-back direction in a sliding mode; locking bolts are arranged on the inner wall surface of the fastening cover; locking grooves are arranged on the inner sleeve; the locking groove comprises a transverse groove which extends along the circumference direction of the inner sleeve and a longitudinal groove which extends from front to rear of the transverse groove which is connected and communicated with the longitudinal groove; the rear end of the fastening cover is provided with introversive edges and a top tight spring is arranged between the inner side of the introversive edges and the inner sleeve in a top mounting mode; pin holes are formed on the controlling part, pin columns are fixedly arranged at the introversive edges of the fastening cover, every pin column is directed at a corresponding pin hole when the locking bolt is located in the transverse groove, and accordingly the loose problem of the existing nut screw mechanism is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an anti-loose nut screw mechanism and an electrical connector using the mechanism. Background technique [0002] With the rapid development of integration and modularization of electrical equipment, the application of electrical connector components is becoming more and more extensive. In some special occasions, some electrical connectors cannot adopt the conventional mating method due to the large mating force. It is necessary to use a nut and screw structure to convert the rotational torque between the nut and the screw into the axial mating torque of the electrical connector. However, under some load conditions, looseness between the nut and the screw will inevitably occur, which will directly lead to the failure of the locking of the electrical connector, resulting in accidental disconnection or poor contact of the electrical connector. Therefore, it has become a top pri...
