[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the optical port crimping fixture of this utility model mainly includes a positioning mechanism and a hand-held mechanism. The positioning mechanism is used to fix the circuit board 3, and the hand-held mechanism is used to fix the optical port 4. During crimping, the hand-held mechanism is located above the positioning mechanism, with a gap between the two. The pins of the optical port 4 are aligned with the pin pre-drilled holes of the circuit board 3 one by one. Under the action of the press 8, the optical port 4 is crimped onto the circuit board 3.

[0028] The positioning mechanism mainly consists of a base plate 1 and pads 2. The pads 2 support the circuit board 3, and each pad 2 is mounted on the base plate 1. The base plate 1 and pads 2 can be fixedly connected by screws, and can be installed using a sliding groove and slider method. The number of pads 2 corresponds to the number of optical ports 4 to be installed on the circuit board 3, and the distance between adjacent pads 2 can be adjusted according to the designed distance between the optical ports 4 on the circuit board 3.

[0029] Preferably, in the above-mentioned positioning mechanism, such as Figure 2 As shown, the base plate 1 has a sliding groove along its length from the top surface downwards for slidingly mounting the pad 2. A scale is provided on one side of the upper end of the base plate 1 for adjusting the distance between two adjacent pads 2. The bottom of the base plate 1 has two long screw holes for fixing the pad 2 along its length. The diameter of the screw hole should be slightly smaller than the diameter of the screw to facilitate fixing the pad 2 and the base plate 1 when tightening the screw.

[0030] Preferably, in the above-mentioned positioning mechanism, such as Figure 3 As shown, each of the pads 2 has a groove on its top to prevent the pins from bending during the crimping process of the optical port 4. The position and shape of the groove in the figure are only schematic. Each of the pads 2 can be provided with a boss on both sides of the lower part for sliding installation with the base plate 1, and each of the pads 2 can be provided with a screw hole at the bottom for fixing to the base plate 1. The screw is tightened from the bottom of the base plate 1 upwards.

[0031] The handheld mechanism mainly consists of a support bar 5 and a support block 6. A handle is located at the lower end of one side of the support bar 5, and a support block 6 for mounting the optical port 4 is located at the upper end of the opposite side. The support bar 5 and support block 6 can be fixedly connected by screws, or they can be installed using a sliding groove and slider mechanism. The number of support blocks 6 corresponds to the number of optical ports 4 to be installed on the circuit board 3. The distance between adjacent support blocks 6 can be adjusted according to the designed distance between the optical ports 4 on the circuit board 3.

[0032] Preferably, in the above-mentioned handheld mechanism, such as Figure 4 As shown, the top of the support bar 5 may be provided with a scale for adjusting the distance between two adjacent support blocks 6. The lower front part of the support bar 5 may be provided with a handle integrally formed therewith. The upper rear part of the support bar 5 may be provided with a sliding groove for slidingly installing the support block 6 along the length direction. The upper part of the support bar 1 is provided with a long strip-shaped screw hole for fixing the support block 6 along the length direction. The screw hole runs through the front and back of the support bar 1. There is one long strip-shaped screw hole in the figure. The diameter of the screw hole should be slightly smaller than the diameter of the screw to facilitate the fixed connection of the support bar 5 and the support block 6 when tightening the screw.

[0033] Preferably, in the above-mentioned handheld mechanism, such as Figure 5 As shown, each support block 6 has a screw hole at one end for fixing to the support strip 5 and a boss for sliding installation with the support strip 5. The other end of each support block 6 is configured to match the optical port 4 it fits into, preventing damage to its internal structure when the end is pressed into the optical port 4. Figure 6 As shown. During crimping, the upper end of the optical port 4 can be placed as follows. Figure 7 The pressure plate 7 is shown.

[0034] The crimping process of a 4-port optical fiber: as follows Figure 8 As shown, a pad 2 is slid into the groove of the base plate 1 from one end, and the pad 2 and the base plate 1 are fastened with screws. The assembled positioning mechanism is placed on the operating table of the press machine 8. Then, the circuit board 3 is placed on the pad 2, and the reserved position of the optical port of the circuit board 3 is aligned with the groove on the top of the pad 2. One end of the support block 6 is slid into the groove of the support strip 5, and the support block 6 and the support strip 5 are fastened with screws. The other end of the support block 6 is inserted into the optical port 4, with the pins of the optical port 4 facing down. The operator holds the handle of the support strip 5 and places the optical port 4 above the circuit board 3, leaving a gap between them. By observing the horizontal movement of the hand-held mechanism, it is ensured that the pins of the optical port 4 correspond one-to-one with the reserved holes of the optical port pins on the circuit board 3. The pressure plate 7 is placed on the optical port 4, and the press machine 8 is started to slowly press the pins of the optical port 4 into the circuit board 3.

[0035] The crimping process for multiple optical ports 4: In this process, each optical port 4 requires one pad 2 and one support block 6. Specifically, the corresponding number of pads 2 are slid one by one into the groove of the base plate 1 from one end. According to the design dimensions between the multiple optical ports 4 on the circuit board 3, the spacing between the pads 2 is adjusted using the scale on the base plate 1. After adjustment, the base plate 1 and all the pads 2 are fastened with screws. The assembled positioning mechanism is placed on the operating table of the press 8. Then, the circuit board 3 is placed on all the pads 2, and the reserved positions of all optical ports on the circuit board 3 are aligned with the top grooves of all the pads 2. One end of each of the corresponding number of support blocks 6 is slid into the groove of the support bar 5. According to the design dimensions between the multiple optical ports 4 on the circuit board 3, the spacing between the support blocks 6 is adjusted using the scale on the support bar 5. After adjustment, the support bar 5 and all the support blocks 6 are fastened with screws. The other end of each support block 6 is inserted into an optical port 4, with the pins of all optical ports facing downwards. The operator holds the handle of the support bar and places all the optical ports 4 on the circuit board 3 with a gap between them. By observing the horizontal movement of the hand-held mechanism, the operator ensures that the pins of all the optical ports 4 correspond one-to-one with the pre-drilled holes for the optical port pins on the circuit board. The operator then places the pressure plate 7 on all the optical ports 4 and starts the press machine 8 to slowly press the pins of all the optical ports 4 into the circuit board 3.
