Description

Technical Field

[0001] This application relates to the field of optical module jumper cable manufacturing technology, and in particular to an adjustable length curing fixture for optical module jumpers. Background Technology

[0002] As a core component of data centers and communication networks, the precision and consistency of the internal patch cords in optical modules directly affect the quality of optical signal transmission. With the development of technologies such as 5G and cloud computing, the market demand for optical modules is growing rapidly, and the product iteration speed is accelerating. In the production and processing of optical module patch cords, it is usually necessary to manually assemble and connect the patch cord fiber and ferrule together, apply adhesive, and then place it in a curing fixture for curing.

[0003] Given the significant differences in market requirements for short jumper wire lengths, the traditional approach is to design a dedicated curing fixture for each length of short jumper wire to meet the curing needs of different lengths. This undoubtedly increases production costs considerably, thus requiring further improvement. Utility Model Content

[0004] To meet the curing requirements for short jumpers of optical modules of different lengths, this application provides an adjustable curing fixture for short jumpers of optical modules.

[0005] This application provides an adjustable-length curing fixture for optical module short jumpers, which adopts the following technical solution: An adjustable length fixing fixture for optical module jumpers includes a heating plate. A ferrule positioning block is fixedly connected to one side of the upper end face of the heating plate. The ferrule positioning block has a ferrule positioning groove for the ferrule body to be engaged. The upper end face of the heating plate is provided with a short fiber adjustable block and a long fiber adjustable block that slide towards or away from the ferrule positioning block. The short fiber adjustable block is located between the ferrule positioning block and the long fiber adjustable block. The short fiber adjustable block and the long fiber adjustable block are respectively provided with plug positioning grooves for the short fiber plug and the long fiber plug to be engaged. The heating plate is provided with an adjusting component for adjusting the sliding position of the short fiber adjustable block / long fiber adjustable block.

[0006] By adopting the above technical solution, the short jumper wires of the optical module can be positioned by using the ferrule positioning groove to hold the ferrule body and the plug positioning groove to hold the short fiber plug and the long fiber plug; by adjusting the sliding position of the short fiber adjustable block and the long fiber adjustable block by adjusting the adjustment component, the curing requirements of short jumper wires of different lengths can be met, avoiding the need to design a special curing fixture for each length and reducing production costs.

[0007] Preferably, the ferrule positioning block, the short fiber adjustable block, and the long fiber adjustable block are all strip blocks arranged parallel to each other. The length direction of the ferrule positioning block is parallel to the length direction of the heating plate. Multiple ferrule positioning slots are provided and are evenly distributed along the length direction of the ferrule positioning block. Multiple plug positioning slots are provided and are evenly distributed along the length direction of the short fiber adjustable block / long fiber adjustable block.

[0008] By adopting the above technical solution, the ferrule positioning block, short fiber adjustable block, and long fiber adjustable block are arranged in parallel to each other and are strip-shaped blocks. The length direction of the ferrule positioning block is parallel to the length direction of the heating plate, making the fixture structure more regular and orderly. The ferrule positioning groove and the plug positioning groove are evenly distributed along the length direction of the corresponding block and multiple grooves are provided. Multiple ferrule bodies, short fiber plugs, and long fiber plugs can be positioned at the same time, which improves the efficiency of the fixture and can meet the needs of mass production.

[0009] Preferably, a pair of guide rails are protruding and fixed on the heating plate, respectively located on both sides of the insert positioning block. Slider blocks are protruding and fixed on both sides of the short fiber adjustable block / long fiber adjustable block, and a guide groove is opened on the lower end face of the slider to slide and cooperate with the guide rails.

[0010] By adopting the above technical solution, the slider can slide and cooperate with the guide rail through the guide groove, which can ensure that the short fiber adjustable block and the long fiber adjustable block slide stably on the heating plate towards or away from the core positioning block.

[0011] Preferably, a fixing block is fixedly connected to the heating plate. The fixing block is located on the side of the long fiber adjustable block away from the insert positioning block. The adjusting component includes a short fiber adjusting screw rotatably connected between the insert positioning block and the fixing block. The short fiber adjusting screw is threaded through the short fiber adjustable block. A first through hole is provided through the side wall of the long fiber adjustable block for the short fiber adjusting screw to pass through.

[0012] By adopting the above technical solution, rotating the short fiber adjusting screw can move the short fiber adjustable block along the screw, thereby adjusting the position of the short fiber adjustable block; the side wall of the long fiber adjustable block is provided with a first through hole for the short fiber adjusting screw to pass through, so as to avoid the short fiber adjusting screw interfering with the movement of the long fiber adjustable block.

[0013] Preferably, the adjusting component further includes a long fiber adjusting screw rotatably connected between the insert positioning block and the fixing block. The long fiber adjusting screw is threaded through the long fiber adjustable block, and a second through hole is provided on the side wall of the short fiber adjustable block for the long fiber adjusting screw to pass through.

[0014] By adopting the above technical solution, the position of the long fiber adjustable block can be precisely adjusted by rotating the long fiber adjusting screw. The second perforation on the side wall of the short fiber adjustable block allows the long fiber adjusting screw to pass through, thus avoiding the long fiber adjusting screw from affecting the normal adjustment of the short fiber adjustable block.

[0015] Preferably, one end of both the short fiber adjusting screw and the long fiber adjusting screw protrudes from the outer wall of the insert positioning block, and the ends of both the short fiber adjusting screw and the long fiber adjusting screw are coaxially fixedly connected with knobs.

[0016] By adopting the above technical solution, the knob is designed to facilitate the operator's rotation of the short fiber adjusting screw and the long fiber adjusting screw.

[0017] Preferably, the upper end face of the guide rail is provided with a threaded hole, and multiple threaded holes are provided and evenly distributed along the length direction of the guide rail. A fixing bolt threaded into the threaded hole is provided on the slider, and the nut end face of the fixing bolt abuts against the upper end face of the slider.

[0018] By adopting the above technical solution, the threaded holes evenly distributed on the guide rail cooperate with the fixing bolts on the slider. After the short fiber adjustable block and the long fiber adjustable block are adjusted to the appropriate position, they can be fixed by tightening the fixing bolts to prevent their position from moving during the curing process and ensure the accuracy of the curing length of the short jumper wire.

[0019] Preferably, the upper end face of the slider has a through hole, which is a strip-shaped hole. The length direction of the through hole is parallel to the length direction of the guide rail, and the length of the through hole is greater than the distance between the two threaded holes. The fixing bolt passes through the through hole.

[0020] By adopting the above technical solution, the length direction of the strip-shaped through hole is parallel to the guide rail and the length is greater than the distance between the two threaded holes, so that the fixing bolt can move along the length direction of the guide rail in the through hole. This facilitates fixing the slider at the threaded hole at different positions, realizing the fixing of the short fiber adjustable block and the long fiber adjustable block at different positions, and enhancing the flexibility of the fixture adjustment.

[0021] In summary, this utility model has the following beneficial effects: 1. By using the ferrule positioning slot to hold the ferrule body and the plug positioning slot to hold the short fiber plug and the long fiber plug, the short jumper wire of the optical module can be positioned; by adjusting the sliding position of the short fiber adjustable block and the long fiber adjustable block, the curing requirements of short jumper wires of different lengths can be met, avoiding the need to design a special curing fixture for each length and reducing production costs. 2. Multiple ferrule positioning slots and plug positioning slots are evenly distributed along the length of the corresponding blocks, which can simultaneously position multiple ferrule bodies, short fiber plugs and long fiber plugs, improving the efficiency of the fixture and meeting the needs of mass production. 3. The threaded holes evenly distributed on the guide rail cooperate with the fixing bolts on the slider. After the short fiber adjustable block and the long fiber adjustable block are adjusted to the appropriate position, the fixing bolts are tightened to fix them, preventing their position from moving during the curing process and ensuring the accuracy of the curing length of the short jumper wire.
