Abstract
The utility model discloses a kind of SMP J-types radio frequency (RF) coaxial connector, the SMP J-types radio frequency (RF) coaxial connector includes inner wire, insulator, shell, and the inner wire, insulator, shell are set gradually from inside to outside, and the shell interfaces root is equipped with chamfering；And the shell is lengthened to inserting face root.The utility model is when with SMP KK types connectors to inserting, since SMP J-type radio frequency (RF) coaxial connectors root chamfering always can be to outside thrust there are one SMP KK types connectors, balance the state that gap caused by the tolerance stack of multistage blind hole dimension chain is retained in SMP J radio frequency (RF) coaxial connectors one end, so that gap caused by the tolerance stack of multistage blind hole dimension chain is not interfered with high frequency performance within 0.5mm and (is evenly distributed with gap, clearance limit≤0.25 for making the both ends SMP KK, meets professional standard).
Description
Technical field
The utility model relates to a kind of connector, especially a kind of SMP-J types radio frequency (RF) coaxial connector.
Background technology
With the needs of whole set equipment miniaturization, SMP train of radio frequency coaxial connector is because of its small, weight
Gently, shock resistance is good, working band is wide, allows the axially and radially misalignment degree for having certain, is widely used in integrated modular field
It closes.Having for the system of strict demand to volume, weight in airborne radar and phased array etc., SMP series connectors receive favor,
It realizes that feeder line is omitted with module docking in module or other cables connect, comes by SMP-KK jack to jack adapter adapters between two modules
Connection conducting, is greatly saved space and weight.But two modules, SMP-J types radio frequency (RF) coaxial connector, SMP jack to jack adapters are transferred
Tolerance is individually present in device, and docking gets up to have prodigious tolerance stack, and by the tolerance stack of multistage blind hole dimension chain, the limit is to inserting
Existing gap after the completion can generally be controlled in -0.1~+0.5mm, and there are will produce following two problems when limit tolerance：
1. when if gap reaches limes superiors, SMP-KK left ends and half escapement (- L) connector of SMP-J types to inserting, right end with
When SMP-J type unthreaded hole (- S) connectors are to inserting, SMP-J types half escapement (- L) connector can be by SMP-KK jack to jack adapters adapter toward certainly
One's own side Xiang La causes above-mentioned gap all to stay in SMP-J type unthreaded hole (- S) connector end, this will influence the high frequency of system
Energy；
2. when if gap reaches limit inferior, it is understood that there may be SMP-KK jack to jack adapter adapters withstand the connection of SMP-J type RF coaxials
Device causes plank that can not damage being inserted into position or connector.
Board to board connector installation requirement is as follows in industry at present：
1. radial misalignment
Radial misalignment R in board to board connector installation process refers to the same of the contact pin contacting piece connector on two plates
Heart deviation, as shown in Figure 2.Maximum radial misalignment R should be controlled within the scope of ± 0.25mm.
3. axial misalignment
Axial misalignment A in board to board connector installation process refers to the contact pin contacting piece company of unthreaded hole or braking device
The gap between device and jack contact adapter reference plane is connect, as shown in Fig. 1.Maximum axial misalignment A should be controlled in 0.25mm
In range.
But the SMP-J types radio frequency (RF) coaxial connector of existing normal structure and SMP-KK jack to jack adapters adapter 7 currently on the market
After inserting, it will not float, gap caused by the tolerance stack of multistage blind hole dimension chain can not be made up.
In this context, it is badly in need of a kind of connector or adapter that can cause to dock radial expansion occur, to make up multistage
Gap caused by the tolerance stack of blind hole dimension chain, and high frequency performance cannot be influenced, and there is high reliability.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of SMP-J types RF coaxial connection
Device.The utility model uses following technical scheme to achieve the above object：
A kind of SMP-J types radio frequency (RF) coaxial connector, the SMP-J types radio frequency (RF) coaxial connector include inner wire, insulator,
Shell, the inner wire, insulator, shell are set gradually from inside to outside, and the shell interfaces root is equipped with chamfering；And it is described outer
Shell is lengthened to inserting face root.
Preferably：Shell increases by 0.4 × 45 ° of chamfering in half escapement end interface root.
Preferably：Shell is lengthening 0.2mm to inserting face root, makes partly catching SMP-KK jack to jack adapters adapter during inserting
There are the gaps of 0.2mm at vertical end.
This practicality provides a kind of novel SMP-J types radio frequency (RF) coaxial connector, when with SMP-KK types connector to inserting,
Since SMP-J type radio frequency (RF) coaxial connectors root chamfering always can be to outside thrust there are one SMP-KK types connectors, balance
Gap caused by the tolerance stack of multistage blind hole dimension chain is retained in the state of SMP-J type radio frequency (RF) coaxial connectors one end, makes
Gap caused by the tolerance stack of multistage blind hole dimension chain does not interfere with high frequency performance within 0.5mm and (is evenly distributed with gap, makes
Clearance limit≤0.25 at the both ends SMP-KK, meets professional standard).

Specific implementation mode
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of SMP-J types radio frequency (RF) coaxial connector, the SMP-J types radio frequency (RF) coaxial connector includes interior leads
Body 1, insulator 2, shell 3, the inner wire 1, insulator 2, shell 3 are set gradually from inside to outside, 3 interface root of the shell
Equipped with chamfering 4；And the shell 3 is lengthened to inserting face root.
Wherein, shell increases by 0.4 × 45 ° of chamfering in half escapement end interface root；Shell is lengthened to inserting face root
0.2mm, make to insert during SMP-KK jack to jack adapters adapter at half escapement end, there are the gaps of 0.2mm.
The utility model provides a kind of novel SMP-J types radio frequency (RF) coaxial connector, with SMP-KK types connector to insert
When, since SMP-J type radio frequency (RF) coaxial connectors root chamfering always can equal outside thrust there are one SMP-KK types connectors
Gap caused by the tolerance stack of multistage blind hole dimension chain of having weighed is retained in the state of SMP-J type radio frequency (RF) coaxial connectors one end,
Make gap caused by the tolerance stack of multistage blind hole dimension chain not interfere with high frequency performance within 0.5mm (to be evenly distributed with gap, make
Clearance limit≤0.25 at the both ends SMP-KK, meets professional standard).
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention with spirit, the change that is carried out to embodiment is repaiied
Change, replace and modification is still fallen within the scope of protection of the utility model.
