Embodiment
Refer to shown in Fig. 1, Fig. 2, the application card connector includes insulating body 10, is shaped in the insulating body
Terminal group 2 and metal insert 30 in 10.The terminal group 2 with the metal insert 30 is integrally rushed by sheet metal
Swaging into, before being integrally formed with the insulating body 10, the terminal group 2 and the metal insert are connected by material strip
It is integrated.
Further referring to shown in Fig. 3, Fig. 4, Fig. 5, the terminal group 20 is included in two rows of plug-in card direction arrangement, often arranged
Three conducting terminals 20.Holding parts 21 that each conducting terminal 20 includes being shaped in the insulating body 10, described in
The leg 22 and elastic arm 23 that the extension of holding parts 21 is formed.The elastic arm 23 includes being inclined upwardly extension from the holding parts 21
First elastic portion 231 of formation, the end of the first elastic arm 231 is formed at for being contacted with what the golden finger of electronic card contacted
Portion 233, tilt down to extend the second extension 232 formed and be formed at described second from after the bending of contact site 233 and prolong
The end 234 of the end of extending portion 232.The holding parts 21 of two row's conducting terminals 20 are located at the insulating body 10 close to middle position
Put, the elastic arm 23 with described insert then to move back card direction and stretch out at an angle, i.e., two row's conducting terminals 20 are formed
"eight" shape structure.Between the elastic arm 23 and the slotting angle substantially 15-35 degree moved back between card direction, it is preferred with 25 degree.
Refering to shown in Fig. 4, Fig. 5, the second extension 232 of the conducting terminal 20 is included from the contact site 233 emphasis
Extended after bending with smaller angle of inclination the connecting portion 2321 to be formed and from the end of connecting portion 2321 again bending with larger
Angle of inclination extends the supporting part 2322 to be formed.The end 234 is formed from the ends bent of supporting part 2322.It is described
The angle of inclination of supporting part 2322 is more than the angle of inclination of first extension 231, the inclination angle of first extension 231
For degree more than the angle of inclination of the connecting portion 2321, angle of inclination described herein refers both to the angle between horizontal plane.It is described to connect
Vertical range between contact portion 233 and the holding parts 21 is more than the vertical range between the contact site 233 and end 234.
The elastic arm 23 is tiltedly stretched out with "eight" shape can be effectively increased the development length of the elastic arm 23, strengthen elastic arm
23 elastic deformation intensity.And the connecting portion 2321 is used as buffer part, and first extension 231, supporting part 2322 divide
Not Zuo Wei two fulcrums, the increasing at the angle of inclination of supporting part 2322 can be that the contact site 233 provide more with connecting portion 2321
More deformation spaces is to strengthen elastic force.
Please emphasis as shown in fig.5, the metal insert 30 can effectively strengthen the overall strong of the insulating body 10
Degree, and after integrated injection molding, the metal insert 30 will be connected and the material strip of terminal group 2 is cut off.The metal insertion
The pressing part 31 that part 30 is formed above the end 234 in the opening position turnover extension of end 234 of the conducting terminal 20,
The pressing part 31 can be formed from the both sides of the end 234 or front end turnover extension.The pressing part 31 suppress in
The top of end 234 of the conducting terminal 20, can prevent electronic card insert move back card when, make because wiping and hanging the conducting terminal 20
The elastic arm 23 of conducting terminal 20 produces irreversible buckling deformation.The end 234 of the conducting terminal 20 is perpendicular to described
The direction mountain extension in plug-in card direction is rolled over downwards formed with fixture block 235, the pressing part 31 in the neighbouring side of conducting terminal 20
It is curved at least partly to be overlapped on card direction in slotting move back with the snap fit 32 formed with snap fit 32, the fixture block 234.When electronic equipment is sent out
When life is dropped or runs into strong vibration, the end 234 of the conducting terminal 20 may eject the pressure because of sharp pounding
Portion 31 processed and cause to damage, the snap fit 32 of the fixture block 235 of the end 234 of conducting terminal 20 and the pressing part 31 coordinates can be with
Effectively prevent the end 234 of the conducting terminal 20 from departing from problem caused by the compacting of the pressing part 31.
The insulating body 10 runs through below the position of elastic arm 23 of each conducting terminal 20 of the terminal group 20
Space 11 is pushed formed with terminal.The terminal of the insulating body 10 pushes space 11 and is provided with madial wall 12, the pressing part 31
Snap fit 32 and the madial wall 12 be respectively in the both sides of supporting part 2322 of the conducting terminal 20 with the spacing conducting terminal
20 occur without double swerve.
The supporting part 2322 of the extension 232 of conducting terminal 20 second extends into the lower section of pressing part 31, described
Pressing part 31 has been stamped and formed out slope transitions 33, the overbank portion 33 with the position that the supporting part 2322 contacts with each other
Make the pressing part 31 and the smooth contact of supporting part 2322, and the surface of the end 234 is close to the pressing part 31
Surface, avoid Non-smooth surface contact caused by damage and influence wider space.
It should be noted that the pressing part 31 be not limited to turn down from the metal insert 30 or
Turned down from material strip, the metal insert 30 itself can also be material strip, equally can also be the metal material of other purposes
Material.
The application card connector is plugging electronic card by setting pressing part 31 above the end 234 of conducting terminal 20
When wipe hang conducting terminal 20 while, will not make the elastic arm 23 of the conducting terminal 20 that irreversible mechanical shape occur
Become.
