Technical Field

[0001] This utility model relates to the field of optical fiber connection technology, specifically an assembly fixture for optical fiber connection. Background Technology

[0002] PCBA refers to Printed Circuit Board Assembly, which is a functional circuit module formed after all electronic components are installed and soldered on a bare PCB board; optical fiber is short for optical waveguide fiber, a type of fiber made of glass or plastic that can be used as a means of light transmission. The transmission principle is total internal reflection of light;

[0003] Currently, the electrical connection between fiber optic cables and PCBA modules is mainly done manually. Since there are many branches in the fiber optic cables, it is very troublesome to solder each branch individually. In addition, manual operation will result in inconsistent lengths of the branches, which will affect the PCBA soldering effect and thus affect the efficiency of fiber optic connection.

A groove is provided at the front end of the main clamp, and a splitter clamp is provided in the groove. The splitter clamp has an optical fiber clamping groove and two sets of linearly arrayed splitter clamping grooves on its upper part, and the optical fiber clamping groove is located between the two sets of splitter clamping grooves.

[0006] Preferably, the upper part of the branching groove clamp has two through-type adjustment grooves, the horizontal cross-section of the adjustment groove is a rounded rectangular cavity, and the upper part of the main line clamp has threaded grooves at corresponding positions relative to the two adjustment grooves.

[0026] Example: Figure 1 - Figure 7 As shown, this utility model provides a technical solution for an assembly fixture for optical fiber connection, including a main clamp 1. The main clamp 1 has two sets of first fixing components on its upper part, and a wire placement groove 2 is opened on the upper part of the main clamp 1. A groove 10 is opened at the front end of the main clamp 1. A splitter clamp 3 is arranged in the groove 10. The splitter clamp 3 has an optical fiber clamping groove 4 and two sets of linearly arrayed splitter clamping grooves 5 on its upper part. The optical fiber clamping groove 4 is located between the two sets of splitter clamping grooves 5.

[0027] like Figure 3 and Figure 5As shown, the upper part of the branch line clamp 3 has two through-type adjustment grooves 11. The horizontal cross section of the adjustment groove 11 is a rounded rectangular cavity. The upper part of the main line clamp 1 and the corresponding positions of the two adjustment grooves 11 are all provided with threaded grooves. Bolts 12 are provided in the adjustment grooves 11, and the bottom thread of the bolts 12 is set in the cavity of the threaded groove.

[0028] like Figure 3 and Figure 6 As shown, the front end of the main line clamp 1 is formed with an installation groove at the opening of the groove 10. The installation groove is fitted with an optical fiber baffle 6, and a wire groove is formed on the inner wall of the installation groove. A wire rod 7 is fixedly installed at the corresponding position of the optical fiber baffle 6 relative to the wire groove, and the wire rod 7 is adapted to the cavity of the wire groove.

[0029] like Figure 3 and Figure 6 As shown, the fiber optic cable baffle 6 is made of metal, and there are circular grooves at the four corners of the inner wall of the mounting groove. A first magnetic magnet is installed in the circular groove.

[0030] like Figure 1 - Figure 4 As shown, the front end of the main line clamp 1 is connected to the PCBA clamp 8. The PCBA clamp 8 is fixedly provided with two protrusions 9 at one end of the main line clamp 1. The main line clamp 1 is provided with a groove 10 at the corresponding position of the protrusions 9. The protrusions 9 are inserted into the cavity of the groove 10. The upper part of the PCBA clamp 8 is provided with a second fixing component. The upper part of the PCBA clamp 8 is formed with a PCBA placement groove.

[0031] like Figure 1 - Figure 4 As shown, a second magnetic magnet is provided on the inner wall of the groove 10, and the protrusion 9 is made of metal.

[0032] like Figure 3 As shown, guide grooves 13 are provided at the bottom of both the main line clamp 1 and the PCBA clamp 8.

[0033] like Figure 1 - Figure 4 As shown, both the first fixing component and the second fixing component include a wire clamp 14 and a buckle 15. Each set of wire clamps 14 and buckles 15 are rotatably connected to the two sides of the upper part of the main wire clamp 1 and the PCBA clamp 8, respectively. A first inner groove is opened on one side of the clamp 14, and a metal sheet is provided in the cavity of the first inner groove. A second inner groove is opened at the corresponding position of the main wire clamp 1 and the PCBA clamp 8 relative to the inner groove. A third magnetic iron sheet is provided in the cavity of the second inner groove.

[0034] Specifically, a cover plate is fixedly installed on the surface of a set of wire clamps 14 near the PCBA fixture 8 on the first fixing component. The cover plate is in contact with the upper part of the wire distribution groove fixture 3. The buckle 15 can be reset by magnetic attraction or by torque spring. Since it is an existing technical structure and the way it is fastened to other structures is an existing technical means, its specific form and usage will not be described in detail in this application. The wire clamps 14 can be fixed by buckle 15 or by attracting metal sheets with a third magnetic sheet.

[0035] like Figure 1 - Figure 4 As shown, a square groove is provided at the corresponding position of the clamping plate 14 relative to the wire placement groove 2, and a protective pad 16 is provided in the cavity of the square groove. The protective pad 16 is made of silicone.

[0036] Working principle: Place the fiber optic cable into the cable placement slot 2 cavity, then close the cable clamp 14 group away from the PCBA fixture 8, so that the movable end of the cable clamp 14 is aligned or locked in the buckle 15. At this time, the third magnetic piece attracts the metal piece. Then, place the branch wires on the fiber optic cable into the respective branch clamp slots 5 cavities one by one, and place the fiber optic cable into the fiber optic cable clamp slot 4, while bending the fiber optic cable downwards at the same time. Then close the fiber optic cable baffle 6, which blocks the bent fiber optic cable and prevents it from returning to its original shape. The cable rod 7 on the fiber optic cable baffle 6 is then locked into the cable slot cavity. Inside, the first magnetic piece attracts the fiber optic cable baffle 6. At the same time, the wire clamp 14 near the PCBA clamp 8 is positioned so that the movable end of the wire clamp 14 is connected or locked in the buckle 15. At this time, the wire clamp 14 is used to hold the fiber optic cable. Meanwhile, the cover plate covers the upper part of the splitter slot clamp 3. After the fiber optic cable is placed and clamped, the stripping machine is used to strip and cut each branch wire extending from the front end of the main wire clamp 1 to ensure that each branch wire is the same length. After the stripping operation is completed, the inner wires after stripping are dipped in tin to facilitate subsequent soldering.

[0037] Place the PCBA module into the PCBA placement slot cavity, then close the wire clamp 14 on the second fixing component, so that the movable end of the wire clamp 14 is engaged or locked in the buckle 15, thereby fixing the PCBA module with the wire clamp 14. Then, align the PCBA clamp 8 with the main wire clamp 1. The protrusion 9 on the main wire clamp 1 will be inserted into the groove 10 cavity on the main wire clamp 1. At this time, each inner wire on the branch line will be placed on each solder plate on the PCBA module. Then, place the aligned main wire clamp 1 and PCBA clamp 8 into the Hotbar machine for automatic soldering.
