Example 3:
as an alternative embodiment, the present invention is an optical fiber connector comprising a main body portion 1, an optical fiber cable 2, and an insertion portion 3.
Wherein, a cavity 10 is provided in the main body portion 1, and the cavity 10 is mainly used for accommodating the optical cable 2. The optical cable 2 is assembled to the main body 1 and extends into the cavity 10.
The main body 1 is further provided with an insertion portion 3 at one end thereof, and the insertion portion 3 is provided with a fiber ferrule 30 at an end thereof remote from the main body 1. The end of the insertion part 3 is further provided with a cylindrical structure 31 surrounding the optical fiber ferrule 30, the cylindrical structure 31 is mainly used for inserting into a slot 43 of an optical fiber connecting seat matched with an optical fiber connector, the cylindrical structure 31 is arranged at a distance from the optical fiber ferrule 30, and the end face of the cylindrical structure 31 is provided with a first sealing structure 32 (not shown).
Although the first sealing structure 32 is provided on the end face, it is difficult to process relatively, but it can be squeezed tightly after the optical fiber connector is inserted into the optical fiber connector holder and locked, so as to provide a good sealing effect.
Example 4:
as a better alternative, the difference between this embodiment and embodiment 1 is that the first sealing structure 32 is a sealing ring or a plurality of sealing rings arranged at intervals. The sealing ring is adopted for sealing, the sealing effect is good, and the cost is low.
Example 5:
as a better alternative, the difference between this embodiment and embodiment 1 is: for a better mating connection of the fiber connector to the fiber connector receptacle, a locking groove 35 is provided on the insertion portion 3. The clamping groove 35 is matched with the steel ball 46 during butt joint to play a role in clamping and locking.
Example 6:
as a better alternative, the difference between this embodiment and embodiment 1 is: an insertion space 33 is formed between the cylindrical structure 31 and the fiber stub 30, and the position of the first sealing structure 32 is configured such that a plane defined by the position of the first sealing structure 32 and perpendicular to the straight line of the optical cable 2 passes through the insertion space 33. That is, the first seal structure 32 is provided in a region outside the insertion space 33, and the insertion space 33 is inserted by the ferrule housing 42 after the mating, thereby supporting the cylindrical structure 31 to provide a more excellent sealing effect. Further, since the volume of the space for accommodating the tubular structure 31 is small, the sealing effect of the first sealing structure 32 is also improved.
The shape of the insertion space 33 may be set as desired, and in order to provide a better sealing effect, the insertion space 33 in this embodiment is annular.
Example 7:
as a better alternative, in order to reduce the weight, reduce the material, and provide the passage for the optical fiber to pass through, the present embodiment is different from embodiment 1 in that: the insertion portion 3 has a hollow cylindrical structure. The optical cable 2 is provided with an optical cable connector 20 at the end, the optical cable connector 20 is located in the cavity 10, and the optical cable connector 20 is connected with the insertion part 3. The cable connector 20 has a connecting section 21 extending into the insertion portion 3, the connecting section 21 is used for connecting the cable connector 20 and the insertion portion 3, and a second sealing structure 22 is arranged on the connecting section 21, and the second sealing structure 22 is used for isolating the space in the cavity 10 and the space in the insertion portion 3. After the second sealing structure 22 is provided, water can be prevented from flowing into the insertion portion 3 through the cavity 10, and then the possibility that the subsequent water flows to the optical fiber insertion core 30 can be reduced, so that a better sealing and waterproof effect is achieved. Water permeating from the connection between the main body portion 1 and the insertion portion 3 is also blocked at the second sealing structure 22, and the water is prevented from permeating into the insertion portion 3 to affect the optical fiber in the insertion portion 3. Preferably, the second seal 22 is a gasket.
Further, one end of the optical cable connector 20, which is far away from the insertion portion 3, is sleeved with a thermal shrinkage waterproof jacket 23, and the thermal shrinkage waterproof jacket 23 extends from the optical cable connector 20 to the optical cable 2 and extends out of the main body portion 1. The heat-shrinkable waterproof jacket 23 is used to prevent water from penetrating from the tail end of the optical cable connector, and forms an integral sealing area for the optical fiber to pass through together with the first sealing structure 32 and the second sealing structure 22.
In addition, the insertion portion 3 and the main body portion 1 may be integrally formed to enhance the integrity of the optical fiber connector, and of course, the insertion portion 3 may be assembled to the main body portion 1 for the convenience of production.
Example 8:
as an alternative embodiment. The difference between this embodiment and embodiment 1 is that: the insertion portion 3 has a hollow cylindrical structure. The optical cable 2 is provided with an optical cable connector 20 at the end, the optical cable connector 20 is located in the cavity 10, and the optical cable connector 20 is connected with the insertion part 3. Optical cable connector 20 has the linkage segment 21 that stretches into the portion of inserting 3, and linkage segment 21 is used for connecting optical cable connector 20 and the portion of inserting 3, and the pot head that the portion of inserting 3 was kept away from to optical cable connector 20 is equipped with pyrocondensation waterproof jacket 23, pyrocondensation waterproof jacket 23 by the linkage segment is close to optical fiber lock pin 30 one end extends to optical cable 2 and stretches out main part 1.
Because the heat-shrinkable waterproof jacket 23 extends from one end of the joint section 21 close to the optical fiber ferrule 30 to the optical fiber cable 2 and extends out of the main body 1, water can be prevented from flowing into the insertion part 3 through the cavity of the main body 1, and water permeating from the connection between the main body 1 and the insertion part 3 can be blocked at the heat-shrinkable waterproof jacket 23, so that the water is prevented from permeating into the insertion part 3 to influence the optical fiber in the insertion part 3. And can also prevent water from permeating from the tail end of the optical cable connector. Meanwhile, the water seepage at the joint of the main body part 1 and the insertion part 3 can be solved without arranging the second sealing structure 22 on the joint section 21.
Example 9:
as a better alternative, in order to better fit with the optical fiber connector holder and facilitate the butt joint, the insertion portion 3 and the main body portion 1 are both cylindrical, and the diameter of the insertion portion 3 is smaller than that of the main body portion 1, so that the periphery of the insertion portion 3 forms a receiving area 34 for receiving an external structure connected with the optical fiber connector. Because the diameter of the inserting part 3 is small and the inserting part is butted with the optical fiber connector socket at the bearing area 34, the overall diameter can be effectively reduced, and the arrangement density of the optical fiber connecting component is effectively improved.
Referring to fig. 3, the present invention further provides an optical fiber connector, which includes a body 4, wherein one end of the body 4 is provided with a butt portion 40, the butt portion 40 is provided with a butt channel 41, the body 4 is further provided with a ferrule receiving seat 42 for receiving the optical fiber ferrule 30, the ferrule receiving seat 42 is located at the middle portion of the body 4, the ferrule receiving seat 42 extends into the butt channel 41, and a slot 43 is formed between the ferrule receiving seat 42 and the inner wall of the butt portion 40. Since the slot 43 is located in the docking channel 41 and its space is limited, the area of the tubular structure 31 to be sealed after insertion is not large, and sealing in a narrow space will improve the tightness of the first sealing structure 32 on the tubular structure 31, thereby providing an effective seal. And the slot 43 is very close to the inserting core accommodating seat 42, even if the structure of the optical fiber connecting seat is changed by a little structural design, a new water seepage point is brought by the structural change, the sealing structure and the sealing position do not need to be readjusted, the adjustment of the die is convenient when the subsequent product is optimized, and the effect of reducing the cost is further achieved.
Preferably, the end of the ferrule receiving seat 42 in the present invention divides the docking channel 41 into a first section 44 close to the housing 4 and a second section 45 far from the housing 4, and the length of the second section 45 is greater than that of the first section 44. The second section 45 is long enough to provide an effective insertion space to improve the stability of the connection and to provide a location for other components in the peripheral region of the second section 45.
Preferably, the width of the slot 43 matches the thickness of the cylindrical structure 31 of the insertion portion 3 of the optical fiber connector that matches the optical fiber connector receptacle. The matching thicknesses provide good sealing after insertion.
Preferably, the docking portion 40 is provided with a receiving groove 47 extending radially from an outer surface of the docking portion 40, the receiving groove 47 is communicated with the docking passage 41, a holding structure for holding an optical fiber connector adapted to the optical fiber connector holder is provided in the receiving groove 47, and a position where the receiving groove 47 is communicated with the docking passage 41 is not a region where the insertion groove 43 is located. Since the position of the receiving groove 47 communicating with the docking passage 41 is not the region of the insertion groove 43, the first sealing structure 32 can prevent water from entering the region of the optical fiber ferrule 30 through the receiving groove 47, and meanwhile, in order to prevent the retaining structure from falling into the docking passage 41, the bottom of the receiving groove 47 is provided with an arc-shaped stopping part.
Specifically, the slot 43 is mainly used for accommodating the tubular structure 31 of the insertion portion 3 of the optical fiber connector matched with the optical fiber connector holder, the cross section of the slot 43 in the present invention is annular, and the slot 43 is further provided with a steel ball 46 matched with the slot 35. After the optical fiber connector is completely connected to the optical fiber connector holder, the steel ball 46 is located at the upper right of the first sealing structure 32.
The first sealing structure 32 is arranged around the outer surface of the cylindrical structure 31 of the optical fiber connector, and/or the first sealing structure 32 is arranged on the end surface of the cylindrical structure 31. The steel ball 46 is located at the upper right of the first sealing structure 32, even if water penetrates through the area around the steel ball 46, the water will be prevented from further flowing continuously towards the left side of the steel ball 46 under the action of the first sealing structure 32, that is, the first sealing structure 32 can prevent water from entering the area of the optical fiber ferrule 30 from the connection interface of the optical fiber connector and the optical fiber connector holder, so that the loss of the optical fiber caused by water inflow is avoided. Further, since the space of the insertion groove 43 is small, the sealing surface is small, and the sealing property can be further improved.
