Description

Technical Field

[0001] The utility model relates to the technical field of research and development of a dual 4CH optical fiber array + MT production process, and in particular to a tool for assembling an optical fiber array with an optical fiber connector. Background Art

[0002] Since the assembly of MT-FA products requires high precision with an error of approximately ±0.3mm, the currently known fixed-length installation method is to manually assemble them, then use a camera to measure them in the second dimension. Then, if the length does not meet the specifications, manually adjust the product and measure the product length again in the second dimension. In this way, after repeated adjustments, the required length of the product can be achieved. The fixed-length assembly time for one product is about 2 minutes.

[0003] The disadvantages of this fixed-length assembly method include repeated adjustments during length determination, which is time-consuming, inefficient, and unsuitable for mass production. The product is small, and the fiber itself is fragile. Repeated length measurements and the possibility of further length changes during handling and transportation can lead to significant errors, typically around 2% of the standard. This production process requires one or more secondary auxiliary equipment, resulting in high operating costs. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a tool for assembling an optical fiber array with an optical fiber connector, which can accurately determine the length of the product and improve efficiency.

[0025] In some embodiments, three mounting slots are provided, which are, from left to right, a first mounting slot 210, a second mounting slot 220, and a third mounting slot 230. The first mounting slot 210 and the second mounting slot 220 extend parallel to the width direction of the base 100, and the third mounting slot 230 extends at a predetermined angle to the width direction of the base 100. The provision of the first mounting slot 210, the second mounting slot 220, and the third mounting slot 230 facilitates installation of different optical fiber arrays 500 into corresponding slots for positioning.

[0026] In some embodiments, the closed ends of the first and second mounting grooves 210, 220 are configured as rounded corners, while the closed end of the third mounting groove 230 is configured as a rounded rectangular structure. These rounded corners prevent the end face of the optical fiber array 500 from directly contacting the inner wall of the mounting groove, thereby preventing contamination or damage to the end face of the optical fiber array 500. It will be understood that the rounded corners are arc structures, and the edge of the end face of the optical fiber array 500 abuts the arc structure to achieve positioning.

[0027] In some embodiments, the optical fiber connector 600 is provided with a boss structure, the upper end surface of which is configured as an S-plane. The provision of the S-plane facilitates the unified installation of multiple optical fiber arrays 500. It should be noted that the upper end surfaces of the boss structures of multiple optical fiber connectors 600 are approximately on the same S-plane, but not the same S-plane in the strict mathematical sense.

[0028] In some embodiments, the distance between the highest point of the first mounting groove 210 and the S-plane is 58.00±0.05 mm, and the distance between the highest point of the second mounting groove 220 and the S-plane is 54.38±0.05 mm.

[0029] In some embodiments, the distance between the midpoint of the rounded rectangular structure and the S-plane is 54.20±0.05 mm.

[0030] In some embodiments, the base 100 is further provided with an adjustment window 400 , and the adjustment window 400 is used to adjust the optical fiber array 500 .

[0031] In some embodiments, there are multiple adjustment windows 400 .

[0032] In some embodiments, three adjustment windows 400 are provided. This ensures that each optical fiber can be adjusted while reducing the use of processing materials. It should be noted that the lengths of the three adjustment windows 400 are 68 mm, 64.5 mm, and 68 mm.

[0033] In some embodiments, the distance between the two optical fiber connectors 600 is 14 mm.

[0034] In some embodiments, the tooling is made of bakelite to prevent damage to the sharp corners of the optical fiber array 500. In some embodiments, the front face of the optical fiber array 500 is affected by angles. When the front face of the optical fiber array 500 is an inclined surface, the optical fiber array 500 and the third mounting slot 230 have a clearance fit, requiring more space to compensate. The actual positioning point is approximately 0.1 mm shorter than the design value.

[0035] In some embodiments, the base 100 is provided with a sinking groove. When the width of the tooling is greater than 120 mm, a positioning block is installed in the sinking groove. The positioning block is used to support a longer optical fiber array 500.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
