The utility model provides a kind of locking mechanism of high-frequency push-in fast self-locking connector in order to solve the weak point in the above-mentioned background technology, and its direct insertion syndeton butt joint space requirement is not high, and self-locking mechanism can guarantee that butt joint interface is stable.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of locking mechanism of high-frequency push-in fast self-locking connector, its special character is: comprise plug and socket, the plug overcoat is connected with plug body by elastic component, be provided with elastic contact head in the plug overcoat, the shell of elastic contact head and plug fixes, and elastic contact head also blocks jack housing, and little contact head is fixed on the plug body, little contact head also withstands on the jack housing interior step, and the socket inner wire closely links to each other with plug inner conductor.
Above-mentioned elastic contact head is to have the ring-spring body of splitting groove, and there is boss its inside, and there is the inclined-plane boss both sides.
Elastic contact head was many fulcrum structures when above-mentioned jack housing was inserted elastic contact head, and elastic contact head was single fulcrum structure when jack housing was extracted elastic contact head, and elastic contact head is by overcoat protection and spacing.
Above-mentioned jack housing cylindrical has a groove, and groove has the inclined-plane, and the elastic contact head inner convex platform blocks the jack housing groove, and jack housing inside is equipped with sealing ring.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the utlity model has connection rapidly, reliably, vibration resistance and electrical property are fine, and the utility model is low to space requirement, can realize the connector high density, push self-locking, the installation requirement of fast insert-pull, the utility model is easy to use, and application prospect is extensive, has very high economic benefit.
2, the utility model adopts the limit-type retaining mechanism of contact head, slip by the control overcoat, elastic contact head is transformed between single fulcrum and many fulcrums, and control elastic contact head and a housing contacts contact portion plug together angle, limit the strength that the shell insertion is extracted, and guarantee overlapping of electric datum level and mechanical reference surface, plug together the rear interface dimensionally stable, guaranteed that electrical property is good, stable, and had anti-vibration, connected characteristics quick, reliable, easy to use.
