Detailed description of the invention
With reference to the accompanying drawing the utility model is made further to describe and illustrate.
Fig. 1 is the cross-sectional view of the blindmate radio frequency connector of the utility model first choice embodiment.
Fig. 2 is the schematic diagram of the plug of blindmate radio frequency connector in Fig. 1.
Fig. 3 is that the blindmate radio frequency connector of the utility model is applied to the schematic diagram of pcb board connection.
Specific embodiment
Below in conjunction with attached drawing, by the description to preferred embodiments of the present invention, more clearly and completely explain
State the technical solution of the utility model.
As depicted in figs. 1 and 2, the blindmate radio frequency connector of the utility model first choice embodiment includes socket 1 and plug
2。
Socket 1 includes shell 11, center contact pin 12, socket insulator 13.Center contact pin 12 is located at the central axis of shell 11
On line, socket insulator 13 is between center contact pin 12 and shell 11.Annulus 14 is also set up on the inner wall of shell 11, for
Plug 2 contacts.
Plug 2 includes outer conductor 21, elastic hole 22, plug insulator 23.Elastic hole 22 is located in outer conductor 21
On mandrel line, for cooperating with center contact pin 12.Plug insulator 23 is between elastic hole 22 and outer conductor 21.
Outer conductor 21 is provided with multiple slots 210 in one end towards socket 1, these slots 210 along the axially extending of plug 2,
And be evenly distributed on one week of outer conductor 21, so that the end of outer conductor 21 is divided into multiple portions, these part phases
It is separated between neighbour by slot 210, thus there is certain elasticity, form outer conductor elastic slice 211.The freedom of outer conductor elastic slice 211
The center curvature towards outer conductor end face is held, forms the bending section 211a extended towards outer conductor end face, and in outer conductor 21
End face on present chrysanthemum shape.The curved bending part of outer conductor elastic slice 211 arches upward outward, forms convex closure 211b.
Plug insulator 23 is hammerhead shape comprising axially distributed first part 231, second part 232, third portion
Divide 233.First part 231 is located at the end of plug insulator 23, and second part 232 is located at first part 231 and Part III
Between 233, the outer diameter of these three parts is different from, and the outer diameter of second part 232 is greater than first part 231 and Part III
233, the outer diameter of first part 231 is greater than Part III 233.Elastic hole 22 is located at the inside of plug insulator 23.First
Divide on 231 end face and be provided with the hole passed through for center contact pin 12, center contact pin 12 is enabled to pass through the hole, insertion elastic hole 22
In.
The first part 231 of plug insulator 23 protrudes from outer conductor 21, and the bending section 211a of outer conductor elastic slice 211 is free
End is contacted with the side of first part 231, and the round diameter that the bending section free end 211a is surrounded is less than the outer of second part 232
Diameter, thus second part 232 and Part III 233 are limited in the cavity of outer conductor 21, and plug insulator 23 is prevented to be detached from
Outer conductor 21, meanwhile, the hammerhead shape design of plug insulator 23 also limits the movement in the radial direction of outer conductor elastic slice 211
In installs connector, the curved design of outer conductor elastic slice 211 plays mechanical to slotting blindmate correcting well
Effect, while impedance-compensated effect is also played, it is impedance-compensated without platform progress is arranged inside socket, it reduces slotting
The difficulty of processing of seat, meanwhile, outer conductor is integrally formed using mold, to reduce the processing and manufacturing cost of connector.
As shown in figure 3, the blindmate radio frequency connector of the utility model is applied to the connection of a pcb board, the perforation of the first socket 1
With on pcb board, the horizontal Surface Mount of the second socket 3 is welded in another pcb board for welding, and the adapting rod 4 with plug 2 is connected to first and inserts
Between seat 1 and the second socket 3, adapting rod 4 can swing certain angle a radially, and the both ends of adapting rod 4 are to the first socket
1 and second socket 3, using the interface of differentiation, the outer conductor elastic slice 211 of chrysanthemum shape is applied to the first socket of blindmate end 1, test
Data prove that blindmate correcting and impedance matching have remarkable result.
Above-mentioned specific embodiment is only described preferred embodiments of the present invention, and not practical to this
Novel protection scope is defined.Under the premise of not departing from the utility model design conception and scope, this field
Those of ordinary skill is according to verbal description provided by the utility model, attached drawing to made by the technical solution of the utility model
