Abstract
The utility model relates to a looseness-proof and strong vibration resistant free end electric connector which comprises a connecting nut, a head casing, a waveform ring, a ratchet wheel and a ratchet rack. The head casing is installed in the connecting nut; the ratchet rack is installed on the inner wall of the connecting nut; the ratchet wheel is installed on the outer wall of the head casing; the waveform ring is arranged between the ratchet rack and the connecting nut; the electric connector is characterized in that a counter table is arranged on the back of the screwing surface of the ratchet wheel; an axial limit surface is arranged on the outer wall of the head casing; a spring spiced ring is sheathed on the outer wall of the head casing; and front and rear surfaces of the spring spiced ring respectively and tightly compress the surface of the counter table and the surface of the axial limit surface. The electric connector adopts the spring spliced ring to perform surface contact and limit respectively with the head casing and the ratchet wheel so as to prevent the ratchet wheel and the head casing from being separated, the electric connector has the advantages that the structure is simple and compact, the vibration resistance effect is good, the production cost is low, and the service life is long, has the property of high strength vibration at high temperature, and is applicable to long-term use in high-temperature and strong vibration work environment.
Description
Technical field
The utility model 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
At the problem that above-mentioned electric connector structure exists, the purpose of this utility model 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 solution adopted in the utility model is: a kind of locking against violent vibration free-end electric connector, comprise the attaching nut, the head capsule body, wave-shaped ring, ratchet, the sour jujube bar, 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, be provided with wave-shaped ring between sour jujube bar and attaching nut, it is characterized in that the back side that described 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 by heavy stand surface and axial limiting face surface respectively before and after described spring was pieced together circle, prevented the disengagement of ratchet and head capsule body.
Further, described 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, described 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 utility model 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, the defective that easy to wear under long term high temperature, the strong vibration work, easy fracture causes free-end electric connector to disintegrate, ratchet and head capsule body are not thrown off, 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, can eliminate stress automatically under the state that shakes by force especially, and tight collapse is on the external wall of head capsule all the time; And it is that face contact 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 utility model adopt spring piece together circle respectively with head capsule body and ratchet between face contact spacing, 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.
