Optical fiber connector with improved fixing plate

An optical fiber connector, comprising:

• an insulating body including a first end surface and a plurality of receiving holes extending through the first end surface;
• a plurality of optical fibers assembled to the insulating body, each optical fiber including a first extension portion protruding beyond the first end surface;
• and
• a ceramic fixing plate fixed to the insulating body, the fixing plate and the insulating body being made of different materials, the fixing plate including a mating surface, a mounting surface opposite to the mating surface, and a plurality of through holes extending through the mounting surface and the mating surface;
• the plurality of through holes and the plurality of receiving holes being aligned with each other;
• the first extension portion being inserted into a corresponding receiving hole and a corresponding through hole;
• the first extension portion being exposed on the mating surface;
• wherein the optical fiber connector further comprises a guiding and positioning pin;
• the guiding and positioning pin passes through the insulating body and the fixing plate;
• wherein the guiding and positioning pin comprises a main body portion inserted in the insulating body and the fixing plate, a guiding and positioning portion extending from one end of the main body portion and protruding beyond the fixing plate, and an installation portion extending from another end of the main body portion;
• the installation portion defines a locking slit;
• and
• wherein the optical fiber connector further includes a fixing shell arranged opposite to the fixing plate;
• the fixing shell includes a locking wall locked in the locking slit.

An optical fiber connector, comprising:

• an insulating body including a first end surface, a second end surface opposite to the first end surface, a plurality of receiving holes extending through the first end surface, and a receiving chamber extending through the second end surface;
• a plurality of optical fibers assembled to the insulating body, each optical fiber including a first extension portion protruding beyond the first end surface;
• a ceramic fixing plate fixed to the insulating body, the fixing plate and the insulating body being made of different materials, the fixing plate including a mating surface, a mounting surface opposite to the mating surface, and a plurality of through holes extending through the mounting surface and the mating surface;
• the plurality of through holes and the plurality of receiving holes being aligned with each other;
• the first extension portion being inserted into a corresponding receiving hole and a corresponding through hole;
• the first extension portion being exposed on the mating surface;
• a fixing shell defining a receiving space;
• an installation block comprising a first fixing portion inserted in the receiving chamber of the insulating body, a second fixing portion received in the receiving space, and a slot through which the plurality of optical fibers pass;
• and
• a pair of guiding and positioning pins passing through the insulating body and the fixing plate, and protruding beyond the mating surface;
• the pair of guiding and positioning pins are in lock with the fixing shell so as to fix the fixing shell to the insulating body.
