As shown in fig. 9 and 10, which are exploded and cross-sectional side views of a conventional optical fiber connector, it can be seen that the conventional optical fiber connector includes a first housing a, a second housing B and a dust cap C, wherein the top of the first casing A is provided with an inserting part A1, the bottom of the first casing A is provided with a buckling part A2 and a first accommodating space A3 formed inside the buckling part A2, a second containing space B1 is formed inside the second casing B, a concave part B2 and an opening B3 on the concave part B2 are arranged on the casing outside the second containing space B1, and the inside of the second shell B extends and is provided with a guide rail groove B4, the top of the dust cover C is provided with a corresponding clamping tenon C1, and the clamping tenon C1 is sleeved with a spring part C2.

However, when the conventional optical fiber connector is assembled, the dust cap C is inserted from the second receiving space B1 of the second housing B, and the tenon C1 of the dust cap C is pushed into the guide rail groove B4 of the second housing B to a position, and the electronic component D is placed in the first receiving space A3 of the first housing a, and then the first housing a is clamped on the second housing B, and the tenon C1 of the dust cap C is pushed by the inserting portion a1 of the first housing a to be pressed against the guide rail groove B4 of the second housing B to be a position, and the buckling portion a2 of the first housing a is buckled on the concave portion B2 of the second housing B, so that the first housing a and the second housing B can be clamped on the electronic component D to be a position, and a pin E for fixing with the circuit board is inserted through the bottom of the second housing B.
