Standard plug, SC shaped steel bag pins；
The SC shaped steel bag pin is formed by metal caudal peduncle and the pressing of SC types ceramic insertion core；
The grinding angle of the SC types ceramic insertion core is 7.5 ± 0.03 °.
As restriction：The rubber sleeve coordinated with it is cased with outside the SC shaped steel bag pin.
The utility model as a result of above-mentioned technical scheme, its compared with prior art, acquired technological progress
It is：
（1）Ladle pin of the present utility model, which uses, grinds angle as 7.5 ± 0.03 ° of SC type ceramic insertion cores, instead of tradition
6 °/8 ° of ceramic insertion core, it can use in two kinds of optical-fiber networks of EPON, GPON, compatibility is high, applied widely；
（2）Ladle pin of the present utility model, which uses, grinds angle as 7.5 ± 0.03 ° of SC type ceramic insertion cores, compared to grinding
