Dust door structure of optical fiber connector

The present invention provides a dustproof door structure of a fiber optic connector, in particular, a clamping portion is formed at an inner side of the embedding groove at the side wall surface of the seat opening, and an escape hole is provided at a lower portion of the holding portion to provide a seat. When the body is formed, a retaining portion is formed at the inner side of the inserting groove, which facilitates assembly of the shaft post of the dustproof door, thereby achieving the advantages of simple structure, easy mold design, and low manufacturing cost.

According to the rapid development of today's communication technology, and the use of telephones, networks and other communication equipment, the distance between people is getting closer and closer, and the transmission of communication equipment uses telecommunication or optical signals as cable transmission lines. Among them, the optical transmission medium (Fiber Optics) cable is the fastest transmission method, because the optical fiber is made of non-metal materials such as plastic or glass, and has excellent anti-electromagnetic and noise interference capabilities. With the advantages of high bandwidth, light weight, long signal transmission distance and good confidentiality, the optical fiber has gradually replaced the traditional metal transmission line.

At present, there are many types of optical fiber connectors that can be plugged in as optical fibers for transmitting or receiving optical signals on the market. Please refer to the ninth and tenth views, which are respectively an exploded view and a side cross-sectional view of a conventional optical fiber connector. It can be clearly seen from the figure that the conventional optical fiber connector includes a first case member A, a second case member B and a dust cover C, wherein the top of the first case member A is provided with the insertion portion A1, and The bottom of the first shell member A is provided with a fastening portion A2 and a buckle portion A2. The first accommodating space A3 is formed, and the second accommodating space B1 is formed in the second housing member B, and the recessed portion B2 is disposed on the housing outside the second accommodating space B1 and the recessed portion B2 is disposed.

It can be clearly seen from the figure that when the creation is assembled, First, the extension portion 22 of the dustproof door 2 is inserted into the docking space 10 of the docking portion 11 of the base body 1 from the opening 101, and the shaft posts 211 at the two sides of the base portion 21 are along The insertion groove 111 abuts against the guiding inclined surface 1121 of the latching portion 112 which is inclined toward the docking space 10, and is further pushed by the dustproof door 2, and the force of the shaft column 211 is squeezed and is located at the holding portion. Below the 112, the shaft post 211 of the base portion 21 can be pivotally positioned in the embedding groove 111 of the abutting portion 11 to rotate the dustproof door 2 at a predetermined angle, and the elastic member of the shaft post 211 of the base portion 21 is sleeved. 23, the first abutting portion 231 is elastically supported downward at the inner side of the extending portion 22, and the second abutting portion 232 of the elastic member 23 is elastically supported upward at the inner wall surface of the abutting space 10 of the abutting portion 11, so that The dustproof door 2 is in an open or closed state in the abutting portion 11 and has a function of elastic resetting. At the same time, the blocking block 221 protruding from the center of the lower portion of the extending portion 22 is rotated and abutted against the recess 102 at the bottom of the docking space 10. The blocking position is formed, so that the dustproof door 2 can be brought into a closed state when it is not in use, so as to effectively prevent excessive dust or impurities from entering the inside of the base body 1 and adhering to the surface of the light source transmitting and receiving portion 131 of the optical element 13, and ensuring the optical element 13 The quality and stability of signal transmission.

When the shaft post 211 of the dustproof door 2 is engaged under the latching portion 112 along the recessing groove 111 of the base body 1, the latching portion 112 can be used to limit the shaft post 211 of the dustproof door 2 to the embedding slot 111. Therefore, the dustproof door 2 is not easy to be detached when it is opened or closed in the docking portion 11, and the shaft post 211 of the dustproof door 2 is locked and positioned, which is convenient for assembly and can be ensured after assembly. The structural stability can also be elastically supported by the elastic member 23 to have an appropriate elastic preload on the dustproof door 2, thereby making the dustproof door 2 difficult to produce. The occurrence of arbitrary yaw occurs and has a good shielding and isolation effect against dust or impurities.

However, the inner side of the fitting groove 111 of the abutting portion 11 of the present writing body 1 is provided with a convex holding portion 112, which is required when the base body 1 is integrally wrapped and integrally molded by a mold (not shown). By adding the molding structure, the sliders of the specific shape of the two of the male molds can be respectively disposed at the positions of the insertion grooves 111 and the escape holes 113 as a formed structure, and after being clamped with the female mold core, Then, the plastic body is injected into the mold to form the seat body 1 by means of burying and injecting, and after the mold is opened, the male mold core and the female mold core can be separated, and the two sliders of the male mold core are demolded to be embedded. A protruding holding portion 112 is formed at the inner side of the groove 111. The structure of the escape hole 113 is designed to provide a holding portion at the inner side of the insertion groove 111 by using only one set of molds when the seat body 1 is formed. 112, in order to effectively solve the structure of the seat body 1 when the dustproof door 2 is assembled, the structure of the seat body 1 needs to be separately assembled, the number of the molds to be assembled can be increased, the integral components are large and complicated, and the cost is expensive, thereby achieving a simple structure, easy mold design, and manufacturing. The effect is cheaper.

Please also refer to the seventh and eighth figures, which are respectively a side cross-sectional view of the preferred embodiment of the present invention and a side cross-sectional view after use, which can be clearly seen from the figure, wherein the optical fiber connector 3 The inside of the calibration post 31 is an optical fiber core 321 through which the cable 32 is inserted. When the external optical fiber connector 3 is inserted into the abutting portion 11 of the base 1, the calibration post 31 is pushed against the dustproof door 2 On the extension 22, the base 21 is located on the shaft 211 The inner side of the embedding groove 111 is rotated at a predetermined angle as an axis, and is elastically deformed by the extending portion 22 of the dustproof door 2 against the elastic member 23, so that the dustproof door 2 is opened in the abutting portion 11. And the external fiber connector 3 is inserted into the docking space 10 of the docking portion 11, so that the fiber core 321 at the center of the calibration pillar 31 can be aligned with the light source transceiver portion 131 of the optical component 13, and the optical signal and the electrical signal can be performed. After the conversion, the plurality of soldering portions 132 of the optical component 13 can be electrically connected to the predetermined circuit board by surface adhesion technology (SMT) or through hole (Through Hole) for signal transmission.
