Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
One quick plug connector interface of the present invention, including pin connector interface and receptacle connector interface
Two parts.
Pin connector interface is as it is shown in figure 1, include contact pin 1, be arranged on the plug insulator outside contact pin 1
2 and be arranged on the plug body 3 outside plug insulator 2, wherein contact pin 1, plug insulator 2 and insert
The fixed form of head shell 3 is optional (embedding of optional routine is fixed, agnail is fixed and other version),
But need to meet this technical requirement of stationarity of central contact, wherein interfacial structure right-hand member is that air is situated between
Matter, left end be PTFE medium support, all should ensure that impedance matching, plug body 3 to spigot be
Front end with fillet boss, this fillet boss be designed with become with pin connector axis different angles leading to
Angle and rear guide angle, front guide angle is little to reduce insertion force, and rear guide angle is greatly to increase separating force.Preferably,
Front guide angle is 24 °～25 °, and rear guide angle is 42 °～43 °.
Receptacle connector interface is as in figure 2 it is shown, include jack 4, be arranged on the socket insulator outside jack 4
5 and be arranged on the jack housing 6 outside socket insulator 5, wherein jack 4, socket insulator 5 and insert
The fixed form of seat shell 6 is optional (embedding of optional routine is fixed, agnail is fixed and other version),
But this technical requirement of stationarity of central contact, the step to spigot of jack housing 6 need to be met
Being placed with reed 7 in hole, reed 7 is to stick up tooth reed as it is shown on figure 3, be with the matching relationship of jack housing 6
Matched in clearance, is placed on the left of jack housing 6 at the bottom of stepped hole hole during assembling.It is blue or green that resilient key 8 can be selected for beryllium
Copper elastomeric material, is placed on along three groups of holes of lining 9 circumference uniform distribution, and matching relationship is interference fits,
As shown in Figure 4, then lining 9 is pressed in jack housing 6 by the way of interference fit fixing, will simultaneously
Reed 7 is fixed.
During as it is shown in figure 5, pin connector coordinates with socket connector, before plug body 3 fillet boss
Guide angle inserts in resilient key 8, as shown in Figure 6 and Figure 7, outside the front guide angle of 3 jiaos of boss of plug body
Footpath φ d should be less than resilient key 8 inscribed circle diameter φ D, enough guides to obtain；Continue inserting, by connecting
Device coordinates extruding to make resilient key 8 produce the mouth that rises, when the maximum outside diameter φ d1 of plug body 3 fillet boss passes through
During resilient key 8, resilient key produces maximum distortion, and as shown in Figure 8, product should ensure that resilient key 8 produces
During large deformation, intensity meets requirement, should design suitable radial tolerance simultaneously so that pin connector interface and
When receptacle connector interface coordinates, it is allowed to adapter has certain radial direction misalignment, in Fig. 8 shown in dotted line
At the resilient key 8 maximum distortion after reaching maximum tolerance, i.e. distance A is pin connector interface and inserts
The maximum radial misalignment that base connector interface fit is allowed, Fig. 9 is maximum radial misalignment A schematic diagram,
As seen from Figure 9, when misalignment state maximum to slotting formation, resilient key 8 still fixes to clamp shell 3 shape
Become three point contact；Continuing inserting, shell 3, by resilience, is fixed to clamp by resilient key 8, and design should ensure that Fig. 6
The maximum outside diameter φ d1 size of middle plug body 3 fillet boss is more than resilient key 8 inscribed circle diameter φ D, with
Sample should ensure that when maximum misalignment state, and resilient key 8 still fixes to clamp plug body 3 and forms at 3 and connect
Touch, outside i.e. can determine that by 3 three resilient keys knowable to the theories of circumference can be to the plug at pin connector interface
Shell 3 carries out the most spacing, to avoid generation to rock；When pin connector interface and receptacle connector interface are complete
Become after coordinating, the gear piece of the reed 7 that extruding is tilted by the right side of plug body 3, form reliable contacts,
Pin connector also allows for having to the right certain pressure that continues to stick up the gap B of tooth reed as seen from Figure 5, and this gap is
The axial misalignment that pin connector coordinates with socket connector.
This adapter occupation mode is flexible, is not only limited between plate application, also can be widely used to cable, mould
The connection of the types such as block, has wide market prospect.
