Have external cylindrical surface (4.2), external cylindrical surface (4.2) is slidably matched with inner cylinder face (1.5)；The elastic collar (2) blocks simultaneously
Enter interior annular groove (1.4) and outer annular groove (4.1)；The elastic collar (2) is the expanding ring less than a border, elastic collar
(2) opening both ends are pulled open in the axial direction, and the height p of the free state for (2.1) both ends axial direction that is open is greater than elastic collar (2)
Wire cross-section size t.
Escape (1.3) are provided between inner cylinder face (1.5) and internal screw thread (1.1).
Elastic collar (2) is the spring with opening (2.1), is made of elastic wire.
The distance at the opening both ends of elastic collar (2) at least meets elastic collar (2) can be compressed to shell (4) completely
Outer annular groove (4.1).
When the axial width of outer annular groove (4.1) is less than the height p of elastic collar (2), the axis of interior annular groove (1.4)
It is greater than the axial width of outer annular groove (4.1) to width.
When the axial width of outer annular groove (4.1) is greater than or equal to the height p of elastic collar (2), interior annular groove
(1.4) axial width is greater than the height p.
The advantages of invention is the electrical connection conducting and locking for not only realizing tradition connection, but also makes screw thread locking mechanism
With certain anti-loosing effect.

Specific embodiment
Threaded connection Miniature circular electric connector of the invention is described in further detail below in conjunction with above-mentioned attached drawing.
The structural schematic diagram of this present invention of Fig. 1 threaded connection Miniature circular electric connector.Miniature circular is threadedly coupled to be electrically connected
Device is connect mainly to be made of swivel nut 1, elastic collar 2, pedestal component 3 and shell 4.
Fig. 2 is the structural schematic diagram that Novel threaded of the present invention connects swivel nut in Miniature circular electric connector.The inside of swivel nut 1
It is machined with internal screw thread 1.1, escape 1.3, interior annular groove 1.4, inner cylinder face 1.5, outer surface is machined with annular knurl 1.2.Swivel nut 1
Internal screw thread 1.1 is, by screwing swivel nut 1, to plug together connector with other connectors to dock and use with other connectors
In place and have the function that locking.It is provided with escape 1.3 between inner cylinder face 1.5 and internal screw thread 1.1, interior annular groove 1.4
In on inner cylinder face 1.5.Escape 1.3 is the complete machining for its internal screw thread 1.1 and sets, it can be ensured that screw thread it is complete
It screws, also ensures that connector headstock effectively docks in place.Annular knurl 1.2 in outer circle can make connector when in use, can
It is more convenient to be screwed with hand and non-slip.Interior annular groove 1.4 is for installing elastic collar 2.
Fig. 3, Fig. 4 are main view, the top view that Novel threaded of the present invention connects elastic collar in Miniature circular electric connector.
2.1 both ends of opening of elastic collar (2) are pulled open in the axial direction, i.e., when the wire cross-section of composition elastic collar 2 is having a size of the feelings of t
Condition, such as wire rod are round wire rod or rectangular wire, in the case that round gauge or diameter of wire or rectangular wire width are t, elastic card
2.1 both ends of opening of circle 2 have the height p of axial free state, and p ﹥ t.Elastic collar 2 can be for opening 2.1
Spring, be made of elastic wire, length of the coiling less than a circumference.When elastic collar 2 is axial to be compressed, elastic card
Circle 2 is just axially being provided with certain reaction force.
Fig. 5 is the main view that Novel threaded of the present invention connects shell in Miniature circular electric connector.Be inside shell 4 for
Installation pedestal component 3, shell 4 are equipped with external cylindrical surface 4.2, and the outer annular groove of installation elastic collar 2 is equipped on external cylindrical surface 4.2
4.1。
Threaded connection Miniature circular electric connector assembling process of the invention: first strutting the opening 2.1 of elastic collar 2,
Then it packs into the outer annular groove 4.1 of shell 4, is then compressed the opening 2.1 of elastic collar 2 with installs fixture, elasticity
The opening size of retainer ring 2 is it has to be ensured that entire elastic collar 2 can be retracted in the outer annular groove 4.1 of shell 4, finally again by spiral shell
1 set of set when the sliding of the inner hole of swivel nut 1 reaches the position of elastic collar 2, removes installs fixture, continues to slide spiral shell on shell 4
Set 1, the opening 2.1 of elastic collar 2 can make a reservation for open automatically, elastic collar 2 be mounted on simultaneously the interior annular groove 1.4 of swivel nut 1 with
In the outer annular groove 4.1 of shell 4.
After the connector of electric connector of the invention and other cooperations screws, the helical length size p of elastic collar 2 is just
It can be compressed by the annular groove of swivel nut 1 and shell 4, therefore elastic collar 2 will generate axial elastic force, the elastic force is in connector
Meeting generates threaded pre-tightening power, and the axial elastic force and elasticity of the generation of elastic collar 2 to the screw thread 1.1 of swivel nut 1 in use process
The sectional dimension t of retainer ring 2 is related, and the sectional dimension t by increasing elastic collar 2 can increase threaded pre-tightening power.
