Abstract
The utility model relates to a radio frequency coaxial connector with a spring structure, comprising a shell 7of a cable connector, wherein, the shell 7 is connected with one end of a hollow bolt 9 through screw threads; the other end of the hollow bolt 9 is connected with a shell 8; the other end of the shell 8 is provided with a spring 10; the end 10 a of the spring 10 is fixed in the shell 8, thereby simplifying assembly technology, improving rate of finished products, effectively solving the problem that a cable is broken on the root of the connector due to self small bending radius of the testing cable; the connector can be widely applied to cable assembly testing in laboratory environment and harsh service conditions, and has the advantages of high reliability and convenient operations.
Description
Technical field
The utility model relates to a kind of radio frequency connector, relates in particular to a kind of spring structure radio frequency (RF) coaxial connector.
Background technology
Radio frequency (RF) coaxial connector is the interface unit that is widely used in being connected in wireless device and the instrument radio frequency co-axial cable subassembly.At present, radio frequency (RF) coaxial connector great majority adopt the connector heels to add heat-shrink tube, or adopt structure such as heel injection-moulded plastic cover; The heat-shrink tube structure is applicable in the common connector, injection structure needs special injection molding machine and professional mould to guarantee, just can be made into connector assembly, but conventional heat-shrink tube structure is very difficult to realize more number of bends for adopting, and adopt the injection structure expense comparatively expensive.
Summary of the invention
The purpose of this utility model is to provide a kind of spring structure radio frequency (RF) coaxial connector in order to solve above-mentioned the deficiencies in the prior art, has the reliability height, the advantage of being convenient to operate.
For achieving the above object, the technical solution adopted in the utility model is: a kind of spring structure radio frequency (RF) coaxial connector, comprise cable connector shell 7, shell 7 is connected by the end of screw thread with a hollow bolt 9, the other end of hollow bolt 9 is connected with shell 8, the other end of shell 8 disposes a spring 10, and the 10a end of spring 10 is fixed in the shell 8; Be provided with inner wire 3 in the inner chamber of shell 7, between shell 7 and inner wire 3, be provided with dielectric 5, dielectric 5 is fixed on the inner wire 3, cable 11 passes spring 10, shell 8 and hollow bolt 9 and enters in the shell 7, the heart yearn 1 of cable 11 passes dielectric 5 and is connected with inner wire 3, between dielectric 5 and hollow bolt 9 and shell 8, be provided with lining 6, lining 6 and cable shield 4 welding.
Said spring 10 is a tubular coil spring, and the material of spring 10 is six or five manganese, and spring 10 is made of 10b end and 10a end, and the diameter of 10b end is less than the diameter of 10a end.
Because spring 10 does not participate directly in the connector electric performance test; thereby make coaxial connector reach good electric property; spring 10 can be when cable be crooked simultaneously; increase Cable Bending Radius effectively; and simplify assembly technology and improve rate of finished products; it is less because of self bending radius to solve test cable effectively; cable is from the shortcoming of connector heel fracture; realize stronger mechanical performance; the internal structure of protection cable can be widely applied under laboratory environment and the harsh operating condition and carry out cable component test.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, the utility model comprises cable connector shell 7, and shell 7 is connected by the end of screw thread with a hollow bolt 9, and the other end of hollow bolt 9 is connected with shell 8, the other end of shell 8 disposes a spring 10, and the 10a end of spring 10 is fixed in the shell 8; Be provided with inner wire 3 in the inner chamber of shell 7, between shell 7 and inner wire 3, be provided with dielectric 5, dielectric 5 is fixed on the inner wire 3, cable 11 passes spring 10, shell 8 and hollow bolt 9 and enters in the shell 7, the heart yearn 1 of cable 11 passes dielectric 5 and is connected with inner wire 3, be provided with lining 6 between dielectric 5 and hollow bolt 9 and shell 8, lining 6 is connected with cable shield 4.
Referring to Fig. 2, spring 10 is that the close pile warp tempering heat treatment of six or five manganese is become tubular coil spring, and spring 10 is made of 10b end and 10a end, and the diameter of 10b end is less than the diameter of 10a end.
The utility model connector in use, cable 11 enters in the shell 7 by spring 10, shell 8 and hollow bolt 9, the heart yearn 1 of cable 11 is passed dielectric 5 and inner wire 3 welding in the connector, after then lining 6 and cable shield 4 being welded, with hollow bolt 9, spring 10, shell 8, successively shift the position onto after, tighten associated enclosure and nut by spanner.During cable 11 bendings, the recessed edge of the 10b of spring 10 portion is subjected to the effect of external force in the longitudinal direction, and length can be compressed.By its compresses in length, increase Cable Bending Radius effectively, better protection relevant cables.
