Description
Technical field
The utility model relates to radio frequency cable connector technique field, particularly relates to a kind of SMA radio frequency connector with swivel nut self-locking structure.
Background technology
SMA (English full name Sub-Miniature-A) joint, as one of the most frequently used radio frequency connector joint, is widely used in all kinds of various vibration environment such as airborne, vehicle-mounted, when using in vibration environment, needs to adopt and loosens measure reliably.The method of tying up security thread after currently available technology many employings connection on the swivel nut of sub-miniature A connector is carried out locking, this structure is adopted to need process safety silk fixing hole on the swivel nut of SMA, its processing cost is higher than common sub-miniature A connector, and it is also more loaded down with trivial details to tie up security thread, and tie up and be inconvenient to dismantle afterwards, therefore preferably can need to design to lock and not easily loosen, connect SMA radio frequency connector that is reliable, easy installation and removal.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides the SMA radio frequency connector that a kind of locking not easily loosens, connects the band swivel nut self-locking structure of reliable, easy installation and removal.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of SMA connector with swivel nut self-locking structure, it comprises SMA radio frequency connector body, described SMA radio frequency connector body is provided with a locking cutting ferrule, described loosening between cutting ferrule and SMA radio frequency connector body is provided with the Compress Spring that can promote locking cutting ferrule, described SMA radio frequency connector body is also provided with a bayonet lock preventing locking cutting ferrule from being released by Compress Spring, described locking cutting ferrule is provided with the slip bayonet lock groove holding bayonet lock, described slip bayonet lock groove comprises one section of locking slot and one section of anti-rotation groove, described SMA radio frequency connector body connects a swivel nut with snap ring, one end of described swivel nut is provided with ratchet, described locking cutting ferrule is provided with the locking ratchet with the ratchet mating engagement on swivel nut.
The number of teeth of the ratchet on described swivel nut is even number.
When SMA radio frequency connector is in non-installment state, bayonet lock on SMA radio frequency connector body is stuck in the locking slot of the slip bayonet lock groove on locking cutting ferrule, ratchet on locking cutting ferrule and the ratchet on swivel nut are separated from, now swivel nut can rotate freely, and the installation not affecting SMA radio frequency connector connects; After SMA radio frequency connector installs locking, rotate locking cutting ferrule by the bayonet lock on SMA radio frequency connector body from the locking slot of slip bayonet lock groove slippage in anti-rotation groove, eject toward swivel nut direction under being now fastened in the effect of Compress Spring, locking ratchet on locking cutting ferrule is meshed with the ratchet on swivel nut, and be stuck on bayonet lock in anti-rotation groove on locking cutting ferrule, swivel nut just cannot rotate, thus realizes self-locking, can not get loose.
The beneficial effects of the utility model are: adopt said structure, by arranging the locking cutting ferrule compressed by bayonet lock, Compress Spring, locking cutting ferrule is provided with locking ratchet and is meshed with the ratchet on swivel nut, and locking rear thread sleeve cannot rotate, just can realize self-locking, can not get loose.Not easily loosen after the utility model locking, connect reliable, easy installation and removal, be applicable to very much using.
