Specific embodiment
The threaded connection Miniature circular electric connector of the present invention is described in further detail below in conjunction with above-mentioned accompanying drawing.
The structural representation of Fig. 1 this present invention threaded connection Miniature circular electric connectors.Threaded connection Miniature circular electric connector is mainly made up of swivel nut 1, elastic collar 2, pedestal component 3 and shell 4.
Fig. 2 is the structural representation of swivel nut in Novel threaded connection Miniature circular electric connector of the present invention.The inside of swivel nut 1 is machined with internal thread 1.1, escape 1.3, interior annular groove 1.4, inner cylinder face 1.5, and outer surface is machined with annular knurl 1.2.The internal thread 1.1 of swivel nut 1 is used to be docked with other connectors, by screwing swivel nut 1, connector is plugged together in place and is reached the effect of locking with other connectors.Escape 1.3 is provided between inner cylinder face 1.5 and internal thread 1.1, and interior annular groove 1.4 is located on inner cylinder face 1.5.Escape 1.3 is set for the complete machining of its internal thread 1.1, it can be ensured that screwing completely for screw thread, also ensures that the effectively docking of connector headstock in place.Annular knurl 1.2 on cylindrical can make connector when in use, can be convenient screwed with hand and non-slip.Interior annular groove 1.4 is for installing elastic collar 2.
Fig. 3, Fig. 4 are the front view of elastic collar in Novel threaded connection Miniature circular electric connector of the present invention, top view.Elastic collar（2）2.1 two ends of opening pull open in the axial direction, i.e. when situation of the wire cross-section size for t for constituting elastic collar 2, such as wire rod is circular wire rod or rectangular wire, in the case that circular gauge or diameter of wire or rectangular wire width are t, 2.1 two ends of opening of elastic collar 2 have the height p of the free state of axial direction, and p t.Elastic collar 2 can be the spring with opening 2.1, be made up of elastic wire, length of its coiling less than a circumference.When elastic collar 2 is axially compressed, elastic collar 2 is just axially being provided with certain reaction force.
Fig. 5 is the front view of shell in Novel threaded connection Miniature circular electric connector of the present invention.It is that, for installation pedestal component 3, shell 4 is provided with external cylindrical surface 4.2 inside shell 4, is provided with the outer annular groove 4.1 for installing elastic collar 2 on external cylindrical surface 4.2.
The threaded connection Miniature circular electric connector assembling process of the present invention：First the opening 2.1 of elastic collar 2 is strutted, then pack in the outer annular groove 4.1 of shell 4, then the opening 2.1 of elastic collar 2 is compressed with installs fixture, the opening size of elastic collar 2 is it has to be ensured that whole elastic collar 2 is capable of in the outer annular groove 4.1 of indentation shell 4, finally again swivel nut 1 is enclosed within shell 4, when the endoporus of swivel nut 1 slides into the position up to elastic collar 2, remove installs fixture, continue slip swivel nut 1, the opening 2.1 of elastic collar 2 can make a reservation for open automatically, elastic collar 2 is arranged in the outer annular groove 4.1 of interior annular groove 1.4 and shell 4 of swivel nut 1 simultaneously.
After the electric connector of the present invention is screwed with the connector of other cooperations, helical length size p of elastic collar 2 will be compressed by the cannelure of swivel nut 1 and shell 4, therefore elastic collar 2 will produce axial elastic force, the elastic force can produce threaded pre-tightening power to the screw thread 1.1 of swivel nut 1 during connector use, and the axial elastic force that elastic collar 2 is produced is relevant with sectional dimension t of elastic collar 2, threaded pre-tightening power can just be increased by sectional dimension t for increasing elastic collar 2.
