Abstract
The invention relates to an anti-loosening and strong shock-resistant free-end electric connector, which comprises a connecting nut, a head shell, a wavy ring, a ratchet wheel and a ratchet bar, the head shell is mounted in the connecting nut, the ratchet bar is mounted on the inner wall of the connecting nut, the ratchet wheel is mounted on the outer wall of the head shell, the wavy ring is arranged between the ratchet bar and the connecting nut, the back of the closing surface of the ratchet wheel is provided with a sunken terrace, the outer wall of the head shell is provided with an axial limit surface, a spring splicing ring is sleeved on the outer wall of the head shell, and the front and the rear surfaces of the spring splicing ring are respectively compressed by the surfaces of the sunken terrace and the axial limit surface. The spring splicing ring is adopted to be respectively in surface contact with the head shell and the ratchet wheel to limit and prevent the ratchet wheel from being separated from the head shell, and the free-end electric connector has the advantages of simple and compact structure, safe and reliable connection, good shock-resistant effect, low production cost and long service life, has the characteristic of resisting high-intensity shock under high temperature, and therefore is suitable for long-time use in the high-temperature, strong-shock working environment.
Description
Technical field
The present invention relates to the locking against violent vibration free-end electric connector of a kind of electric connector, particularly a kind of screw-type.
Background technology
Traditional free-end electric connector that is threaded, some is to adopt ratchet to carry the structure of elasticity position-limited claw in its anti-loose structure.The elasticity position-limited claw is that line contacts with the axial limiting face of head capsule body; Under long term high temperature, strong vibration work; The defective that position-limited claw is easy to wear, easy fracture causes free-end electric connector to disintegrate; Thereby influence whole electric path, make distorted signals, loss of data, the serious user that causes can't operate as normal.
Summary of the invention
Problem to above-mentioned electric connector structure exists the object of the present invention is to provide a kind of convenience, practicality, and is spacing safe, reliable, the locking against violent vibration free-end electric connector of long service life.
The technical scheme that the present invention adopts is: a kind of locking against violent vibration free-end electric connector, comprise attaching nut, head capsule body, wave-shaped ring, ratchet, sour jujube bar, and the head capsule body is installed in the attaching nut; The sour jujube bar is installed on attaching nut's inwall; Ratchet is installed on the external wall of head capsule, is provided with wave-shaped ring between sour jujube bar and attaching nut, it is characterized in that the back side that said ratchet screws face is provided with heavy stand; The external wall of head capsule is provided with the axial limiting face; Be with spring on the external wall of head capsule and piece together circle, the two sides was compressed with axial limiting face surface by the heavy stand surface respectively before and after said spring was pieced together circle, prevented the disengagement of ratchet and head capsule body.
Further, said ratchet inwall is provided with location notch, and the external wall of head capsule is provided with the positioning key that is mated condition with location notch.
Again further, said sour jujube bar outer wall is provided with positive stop key, and attaching nut's inwall is provided with the stopper slot that cooperates with positive stop key.
The beneficial effect that the present invention reaches is: the sour jujube bar positive stop key nut inner wall stopper slot that is connected is realized sour jujube bar and the synchronous forward or reverse of attaching nut; The ratchet location notch external wall positioning key of head capsule that is connected is realized ratchet and the synchronous forward or reverse of head capsule body, and assurance sour jujube bar and attaching nut, that ratchet is connected with the external wall of head capsule is firm; Be provided with wave-shaped ring between sour jujube bar and attaching nut, the ratchet of assurance sour jujube bar and ratchet meshes does not all the time throw off, and antivibration is effective; The spring that employing increases newly is pieced together circle and is limited in the head capsule axon all the time between confined planes surface and ratchet heavy stand surface; Spring assembly circle can be stopped traditional ratchet and carry the elasticity position-limited claw, and the defective that easy to wear under long term high temperature, the strong vibration work, easy fracture causes free-end electric connector to disintegrate is not thrown off ratchet and head capsule body; Guarantee under any state of free-end electric connector disintegration to take place; Adapt to adverse circumstances such as any high temperature, Qiang Zhen, safe and reliable, reduce production costs; The circle of spring assembly simultaneously has the radial elastic effect, under the state that shakes by force, can eliminate stress automatically especially, and tight collapse is on the external wall of head capsule all the time; And it is that face contacts with head capsule body and ratchet that spring is pieced together circle, and overcoming in the prior art traditional ratchet, to carry the elasticity position-limited claw be that line contacts with the axial limiting face of head capsule body, and it is big that employing face contacts lifting surface area, the enhancing of antivibration ability.
The present invention adopt spring piece together circle respectively with head capsule body and ratchet between face contact spacingly, prevent the disengagement of ratchet and head capsule body, this electric connector structure is simple, compact; Attachment security is reliable; Antivibration is effective, and production cost is low, long service life; Characteristic with the high-intensity oscillation under the high temperature is fit to long term high temperature, the use of strong vibration operational environment.
