[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0021] This application provides a method for manufacturing an optical connection terminal and an optical connection terminal, which can solve the technical problems of high cost and poor sealing effect of sealing methods in related technologies.

[0022] See Figure 1 As shown in the figure, this application provides a method for manufacturing an optical connection terminal, which includes the following steps: S100: A metal wire 3 is placed between the upper cover 1 and the base 2; wherein the upper cover 1 is provided with at least one optical fiber adapter mounting position 11, and the upper cover 1 is provided with an optical fiber receiving cavity.

[0023] S200: Press the upper cover 1 and the base 2 together, and heat the metal wire 3 by electromagnetic induction, so that the upper cover 1 and the base 2 in contact with the metal wire 3 are heat-sealed and fixed.

[0024] See Figure 2 , Figure 3 andFigure 5 As shown, the upper cover 1 can be provided with four fiber optic adapter mounting positions 11, eight fiber optic adapter mounting positions 11, or even more fiber optic adapter mounting positions 11 for installing fiber optic adapters. Different numbers of fiber optic adapter mounting positions 11 are used for different practical application scenarios. This optical connection terminal serves as a fiber optic splice and branching point. It should be understood that in this embodiment, the metal wire 3 is placed between the upper cover 1 and the base 2 near the outer edge of the upper cover 1 and the base 2, and the metal wire 3 wraps around the outer periphery of the upper cover 1 and the base 2 to form a closed metal wire 3. In this embodiment, the metal wire 3 is preferably made of metal steel wire. Of course, other materials can also be used for the metal wire 3, and there is no limitation here. It should be understood that in this embodiment, both the upper cover 1 and the base 2 are made of plastic injection molding. After the metal wire 3 is heated, the plastic material in contact with the metal wire 3 will melt.

[0025] In this embodiment, by placing a metal wire 3 between the upper cover 1 and the base 2 and heating the metal wire 3 using electromagnetic induction, the plastic material between the upper cover 1 and the base 2 in contact with the metal wire 3 can be heated, melted, and fixed together, achieving a sealed fixation between the upper cover 1 and the base 2. Furthermore, the electromagnetic induction heating of the metal wire 3 will not heat components that are not in contact with the metal wire 3, thus preventing damage to the product. At the same time, this fixing method does not require screws, sealing rings, or laser welding equipment, resulting in lower costs and solving the technical problems of high cost and poor sealing effect in related technologies.

[0026] Furthermore, in one embodiment, see... Figure 4 As shown, the bottom surface of the upper cover 1 has a first sealing surface 12, which forms a closed ring around the circumference of the upper cover 1. The base 2 has a second sealing surface 21 that cooperates with the first sealing surface 12, which also forms a closed ring around the circumference of the base 2. The placement of the metal wire 3 between the upper cover 1 and the base 2 includes: placing a metal wire 3 in a closed ring between the first sealing surface 12 and the second sealing surface 21, wherein the extension direction of the metal wire 3 is the same as the extension direction of the first sealing surface 12, so that the first sealing surface 12 and the second sealing surface 21 are in contact with the metal wire 3 at all points in the circumferential direction.

[0027] In this embodiment, the first sealing surface 12 can be a plane, a curved surface, or a bent surface formed by splicing multiple planes; the second sealing surface 21 can be a plane, a curved surface, or a bent surface formed by splicing multiple planes. In this embodiment, both the upper cover 1 and the base 2 are rectangular structures. The first sealing surface 12 forms a square closed ring around the circumference of the upper cover 1, and the second sealing surface 21 also forms a square closed ring around the circumference of the base 2. The square formed by the second sealing surface 21 is the same size as the square formed by the first sealing surface 12. The metal wire 3 also forms a square closed ring with the same shape and size as the second sealing surface 21. The first sealing surface 12 and the second sealing surface 21 can contact the metal wire 3 at various positions in the circumferential direction, so that after heating and melting, the upper cover 1 and the base 2 can achieve good sealing welding at various points in the circumferential direction, and the welding consistency is good.

[0028] Further, in one embodiment, the bottom surface of the upper cover 1 has a sealing protrusion 13, the first sealing surface 12 is disposed on the sealing protrusion 13, the base 2 has a sealing groove 22, the second sealing surface 21 is disposed in the sealing groove 22, and the metal wire 3 is placed in the sealing groove 22. The sealing protrusion 13 protrudes into the sealing groove 22, and both the first sealing surface 12 and the second sealing surface 21 are in contact with the metal wire 3. In this embodiment, a sealing groove 22 is provided on the base 2, and a sealing protrusion 13 is provided on the upper cover 1. A ring of metal wire 3 is located in the sealing groove 22, and a ring of sealing protrusion 13 extends into the sealing groove 22. The sealing protrusion 13 is in contact with the sealing groove 22, and both the sealing groove 22 and the sealing protrusion 13 are in contact with the metal wire 3. When the metal wire 3 is heated by electromagnetic induction, the first sealing surface 12 and the second sealing surface 21 in contact with the metal wire 3 will be thermally fused together in the sealing groove 22.

[0029] In other embodiments, the configuration can be reversed, i.e., a sealing groove 22 is provided on the upper cover 1 and a sealing protrusion 13 is provided on the base 2.

[0030] Furthermore, in some optional embodiments, placing the metal wire 3 between the upper cover 1 and the base 2 may further include: placing at least one segment of the metal wire 3 at the middle position of the base 2, the metal wire 3 being located inside the closed loop metal wire 3, and the metal wire 3 contacting the upper cover 1 and the base 2. In this embodiment, one, two, or more segments of the metal wire 3 may be placed at the middle position of the base 2. See also Figure 7 and Figure 8As shown, four metal wires 3 are placed in the middle of the base 2, each forming a small ring. The middle structures of both the upper cover 1 and the base 2 are in contact with these four metal wires 3, allowing the wires 3 to heat-fuse and fix a portion of the upper cover 1 and the base 2 together when heated. When the optical connection terminal is large or the sealing performance around it is too good, the product is prone to warping and deformation during use. This embodiment adds multiple welding points at the middle of the upper cover 1 and the base 2, fixing the upper cover 1 and the base 2 together at the middle, making the middle of the upper cover 1 less prone to warping and deformation. This embodiment further increases the product's strength with a single welding, solving the risk of warping and deformation after long-term use.

[0031] Furthermore, in one embodiment, the upper cover 1 is provided with a base plate 4, and the base plate 4 and the upper cover 1 form the optical fiber receiving cavity. The upper cover 1 is also provided with a fixing post 14 extending toward the base 2. The fixing post 14 passes through the base plate 4 and is inserted into the base 2, and the fixing post 14 contacts the metal wire 3 at the center of the base 2. See also Figure 6 and Figure 8 As shown, four fixing posts 14 are arranged at intervals inside the upper cover 1. The base 2 has a corresponding insertion slot for each fixing post 14. The fixing post 14 is vertically inserted into the insertion slot and contacts the metal wire 3 in the slot. When the metal wire 3 is heated by an induction magnetic field, the fixing post 14 and the structure in the insertion slot are thermally fused together. In this embodiment, the fixing posts 14 are used to connect the higher parts inside the upper cover 1 to the base 2 for fixation, preventing warping and deformation. It should be understood that the metal wire 3 located in the middle can be either a closed or open wire.

[0032] Further, in some embodiments, pressing the upper cover 1 and the base 2 together and heating the metal wire 3 by electromagnetic induction to heat-seal and fix the upper cover 1 and the base 2 in contact with the metal wire 3 includes: pressing the upper cover 1 and the base 2 together using a welding fixture 5, and energizing the induction heating coil inside the welding fixture 5 to generate an induced magnetic field that heats the metal wire 3 on the base 2. In this embodiment, the welding fixture 5 is placed on the welding equipment, and the upper cover 1 and the base 2 are placed between the upper and lower welding fixtures 5, so that the welding fixture 5 presses the upper cover 1 and the base 2 together. An induction heating coil is fixed inside the welding fixture 5. When the induction heating coil is energized, it can generate an induced magnetic field, thereby heating the metal wire 3 through the principle of electromagnetic induction. This embodiment adopts a high-frequency induced welding scheme, which has good welding strength, good sealing performance, low welding equipment cost, simple welding operation, and good consistency.

[0033] Furthermore, in some optional embodiments, the welding fixture 5 is provided with an annular groove 51 that matches the shape and size of the metal wire 3, and the induction heating coil is accommodated in the annular groove 51. In this embodiment, see [reference needed]. Figure 11 As shown, the welding fixture 5 is used to place the base 2, and the welding fixture 5 has an annular groove 51 inside. The annular groove 51 has the same shape as the metal wire 3, both being rectangular structures. The length and width of the rectangular structure formed by the annular groove 51 and the metal wire 3 are the same. With this arrangement, when the induction heating coil is placed in the annular groove 51 and the base 2 is placed in the welding fixture 5, the induction heating coil and the metal wire 3 are in a vertically aligned position. Each side of the induction heating coil is vertically aligned with each side of the metal wire 3, so that the metal wire 3 can be induction heated.

[0034] It should be understood that four small induction heating coils can also be set in the middle of the welding fixture 5 at positions corresponding to the four metal wire segments 3. The four small induction heating coils are vertically aligned with the four metal wire segments 3 in the middle and are the same size and shape, so as to heat the four metal wire segments 3, so that the four fixing posts 14 are thermally fused and fixed together with the structure in the insertion slot. This embodiment can solve the problem of product warping and deformation during use when the product sealing performance is too good by adopting a multi-point welding scheme.

[0035] from Figure 11 It can also be seen that two lead-out grooves 52 are provided at one end of the welding fixture 5. Both lead-out grooves 52 are connected to the annular groove 51. These two lead-out grooves 52 are used to accommodate the two ends of the induction heating coil, so that the two ends of the induction heating coil are led out and connected to the positive and negative poles for energization. By providing the annular groove 51 and the lead-out grooves 52, the induction heating coil will not obstruct the base 2 after being placed in the welding fixture 5, so that the base 2 can fit tightly with the welding fixture 5.

[0036] See Figure 11 As shown, the welding fixture 5 is also provided with a limiting groove 53. The limiting groove 53 is located at both ends of the welding fixture 5 and is located on the periphery of the annular groove 51. The limiting groove 53 is also provided with two limiting protrusions 54. The limiting groove 53 and the limiting protrusions 54 are used to cooperate with the corresponding structures on the base 2 to limit the base 2.

[0037] Furthermore, in one embodiment, before placing the metal wire 3 between the upper cover 1 and the base 2, the process may further include: installing a first module insert on the port side of the mold body, and injection molding the upper cover 1, which has an optical cable entry interface 15 on the port side, within the mold body. In this embodiment, the structure of the first module insert and the optical cable entry interface 15 are matched, and the first module insert and the mold body can be combined to injection mold the upper cover 1 with the optical cable entry interface 15, realizing an optical connection terminal where an optical cable can enter at the end. In this embodiment, the optical cable entering the optical connection terminal can be a single optical cable, which serves as a fiber optic splice and branching mechanism.

[0038] Furthermore, in some embodiments, before placing the wire 3 between the upper cover 1 and the base 2, the method further includes: installing a second module insert on the port side of the mold body, and injection molding the upper cover 1, which has a termination adapter interface 16 on the port side, into the mold body. Figure 9 to Figure 10 (As shown). In this embodiment, the second module insert and the termination adapter interface 16 are structurally matched. The second module insert and the mold body are combined to form a top cover 1 with the termination adapter interface 16 by injection molding, realizing an optical connection terminal that can be connected to the termination adapter at the end. In this embodiment, the termination adapter can enter the optical connection terminal and enter the housing through the termination connection to play the role of fiber splicing and branching.

[0039] This embodiment uses the same mold body. By only changing the mold port slider (i.e., the first module insert and the second module insert), a single mold body can be used to produce products with multiple functions, reducing the cost of product development.

[0040] This application embodiment also provides an optical connection terminal, which is manufactured using the above-described manufacturing method. The optical connection terminal includes an upper cover 1 and a base 2, and the upper cover 1 and the base 2 are sealed by welding with a metal wire 3. The optical connection terminal in this embodiment can be manufactured using any of the manufacturing methods described in the above embodiments and achieve the corresponding functions, which will not be elaborated further here.

[0041] Furthermore, in one embodiment, the upper cover 1 has an optical cable entry interface 15 or a termination adapter interface 16 on its port side. The optical connection terminal in this embodiment can function with and without cables, achieved simply by changing a port slider in the mold.

[0042] Furthermore, in one embodiment, when the size of the optical connection terminal is large, the upper cover 1 has multiple fixing posts 14 inside, the fixing posts 14 are connected to the base 2, and a metal wire 3 is provided between the fixing posts 14 and the base 2. In this embodiment, when the size of the optical connection terminal is large, a welding structure is added in the middle, and welding is performed simultaneously to strengthen the box body.
