Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
A kind of quick plug connector interfacial structure of the utility model, comprises pin connector interfacial structure and receptacle connector interface structure two parts.
Pin connector interfacial structure as shown in Figure 1, comprise contact pin 1, be arranged on the plug insulator 2 of contact pin 1 outside and be arranged on the plug body 3 of plug insulator 2 outside, wherein contact pin 1, the fixed form of plug insulator 2 and plug body 3 optionally (fix by the embedding of optional routine, hangnail is fixed and other version), but this technical requirement of stationarity of central contact need be met, wherein interfacial structure right-hand member is air dielectric, left end is that PTFE medium supports, impedance matching all should be ensured, plug body 3 to spigot and front end with fillet boss, this fillet boss is designed with the front guide angle and rear guide angle that become different angles with pin connector axis, front guide angle is little of to reduce insertion force, 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 structure as shown in Figure 2, comprise jack 4, be arranged on the socket insulator 5 of jack 4 outside and be arranged on the jack housing 6 of socket insulator 5 outside, wherein jack 4, the fixed form of socket insulator 5 and jack housing 6 optionally (fix by the embedding of optional routine, hangnail is fixed and other version), but this technical requirement of stationarity of central contact need be met, reed 7 is placed with in the stepped hole of jack housing 6 pairs of spigots, reed 7 is for sticking up tooth reed as shown in Figure 3, be matched in clearance with the matching relationship of jack housing 6, to be placed on the left of jack housing 6 at the bottom of stepped hole hole during assembling.Spring pivot 8 can select beryllium-bronze elastomeric material, and be placed on along in three groups of holes of lining 9 circumference uniform distribution, matching relationship is interference fits, as shown in Figure 4, then is pressed in jack housing 6 fixing by lining 9 by the mode of interference fit, is fixed by reed 7 simultaneously.
As shown in Figure 5, when pin connector coordinates with socket connector, the front guide angle of plug body 3 fillet boss inserts in spring pivot 8, as shown in Figure 6 and Figure 7, the front guide angle external diameter φ d of plug body 3 fillet boss should be less than spring pivot 8 inscribed circle diameter φ D, to obtain enough guiding, continue inserting, extruding is coordinated to make spring pivot 8 produce the mouth that rises by connector, when the maximum outside diameter φ d1 of plug body 3 fillet boss is by spring pivot 8, spring pivot produces maximum distortion, as shown in Figure 8, when product should ensure that spring pivot 8 produces maximum distortion, intensity meets the demands, suitable radial tolerance should be designed simultaneously, when pin connector and socket connector are coordinated, connector is allowed to have certain radial misalignment, in Fig. 8, dotted line is depicted as the maximum distortion place of spring pivot 8 after reaching maximum tolerance, namely distance A coordinates the maximum radial misalignment allowed for pin connector and socket connector, Fig. 9 is maximum radial misalignment A schematic diagram, as seen from Figure 9, when misalignment state maximum to slotting formation, spring pivot 8 still fixes to clamp plug body 3 and forms three point contact, continue inserting, spring pivot 8 is by resilience, plug body 3 is fixed to clamp, design should ensure that the maximum outside diameter φ d1 size of plug body 3 fillet boss in Fig. 6 is greater than spring pivot 8 inscribed circle diameter φ D, should ensure when maximum misalignment state equally, spring pivot 8 still fixes to clamp plug body 3 and forms three point contact, can determine that known three spring pivots of the theory of circumference can carry out radial direction to the plug body 3 of pin connector spacing, rock to avoid generation by 3, after pin connector and socket connector complete and coordinate, the right side of plug body 3 is by the gear piece of the reed 7 of extruding tilting, form reliable contacts, pin connector also allows have certain continuation to press the gap B sticking up tooth reed to the right as seen from Figure 5, and this gap is the axial misalignment that pin connector coordinates with socket connector.
This connector occupation mode is flexible, is not only confined to apply between plate, also can be widely used in the connection of the type such as cable, module, have wide market prospects.
