Abstract
A kind of screw thread coupling retaining mechanism, including plug casing and attachment cap, the first convex block is provided in the middle part of the hull outside, circular groove is provided on the right side of first convex block within one week, spring is provided in the circular groove, pellet is connected on the right side of the spring, the second convex block is provided on the inside of the attachment cap, ball hole is evenly arranged within one week on the left of second convex block, the quantity and diameter in the ball hole are identical with the pellet.Stainless steel spring is coordinated using stainless steel marble, while ensure that retaining effect, there is the effect of significant anti-vibration, in addition, pellet and spring high-low temperature resistant, the characteristics of being unlikely to deform, service life is long, reliability is high, and cost is relatively low.
Description
Technical field
The invention belongs to electric connector fields, and in particular to a kind of screw thread coupling retaining mechanism.
Background technology
The backing stop structure of coupling nut is not present in the connector of conventional threads type of attachment, under vibrating conditions the company of easily causing
Connect device plug, socket loosening or even detaching, so as to cause the contact of connector unreliable, until failure, existing threaded connection
The retaining of the coupling nut of form is mainly by way of ratchet, ratchet, if 38999III is serial, though ratchet, ratchet have
Retaining effect, but its rapidoprint is engineering plastics, and mechanical strength, high and low temperature resistance, service life are had a greatly reduced quality, so as to
The effect of its retaining does not maintain the long time, and on the other hand, cost is high.
Invention content
In view of the deficienciess of the prior art, the present invention provides a kind of screw thread coupling retaining mechanism of anti-vibration, to
Solve the problems, such as that screw thread coupling reliable lock is low.
The present invention is achieved by the following technical solutions：
A kind of screw thread coupling retaining mechanism including plug casing and attachment cap, is provided with the in the middle part of the hull outside
One convex block, the first convex block right side are provided with circular groove for one week, spring are provided in the circular groove, bullet is connected on the right side of the spring
Son, the attachment cap inside are provided with the second convex block, and ball hole is evenly arranged within one week on the left of second convex block, the ball hole
Quantity and diameter are identical with the pellet.
It is connected on the outside of the plug casing with the attachment cap inside thread.
The pellet and spring are stainless steel.
Compared with prior art, the beneficial effects of the invention are as follows：Stainless steel spring is coordinated using stainless steel marble, ensure that
While retaining effect, there is the effect of significant anti-vibration, in addition, pellet and spring high-low temperature resistant, the characteristics of being unlikely to deform,
Service life is long, reliability is high, and cost is relatively low.

Fig. 2 is the cross-sectional view of plug casing；
Fig. 3 is the cross-sectional view of attachment cap；
Fig. 4 is the right view of the second convex block.
In attached drawing：1. plug casing；2. attachment cap；3. the first convex block；4. circular groove；5. spring；6. pellet；7. second is convex
Block；8. ball is cheated.
Specific embodiment
Such as a kind of Figure of description Fig. 1 to screw thread coupling retaining mechanism shown in Fig. 2, including plug casing 1 and connect
Cap 2,1 outer middle side part of plug casing are provided with the first convex block 3, and 3 right side of the first convex block is provided with circular groove 4 for one week, is provided in circular groove 4
Spring 5,5 right side of spring are connected with pellet 6, and 2 inside of attachment cap is provided with the second convex block 7, and 7 left side of the second convex block is uniformly set for one week
Ball hole 8 is equipped with, the quantity and diameter in ball hole 8 are identical with pellet 6.
1 outside of plug casing is connected with 2 inside thread of attachment cap.
Pellet 6 and spring 5 are stainless steel.
In practical work process, as attachment cap 2 and the plug casing 1 constantly screw, pellet 6 is beated in ball hole 8,
Compressed spring 5 until pellet 6 is no longer beated, reaches retaining locking effect.
In conclusion only presently preferred embodiments of the present invention, be not used for limiting the range that the present invention is implemented, it is all according to
The equivalent changes and modifications carried out by shape, construction, feature and spirit described in scope of the invention as claimed should all be included in this
In the right of invention.
