[0016] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0017] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] Example 1: like Figure 1As shown in the figure, an inductor terminal fixing base provided by this utility model includes a base plate 2 and a fixing member 1 connected to the upper end of the fixing base. The base plate 2 has symmetrically arranged sliding grooves 22 on its upper surface, a strong adhesive 21 fixedly connected to the lower end of the base plate 2, and an insert block 23 integrally formed on the upper end of the base plate 2. The insert block 23 is located between the sliding grooves 22, and the cross-section of the insert block 23 is L-shaped, with a reserved space between the insert block 23 and the base plate 2. The fixing member 1 includes an upper arc-shaped ring 11 and a lower arc-shaped ring 12. Connecting terminals 111 are fixedly connected to the inner sides of both the upper arc-shaped ring 11 and the lower arc-shaped ring 12. A port 1111 is provided between the connecting terminals 111. The left and right sides of the upper arc-shaped ring 11 and the lower arc-shaped ring 12 are movably connected by a connecting mechanism 13 and a positioning mechanism 14, respectively. A connecting block 15 is integrally formed at the lower end of the lower arc-shaped ring 12, and a through groove 151 is provided on the end face of the connecting block 15. The connecting block 15 is connected to the insert block 23 via the through groove 151. A set of protrusions 152 are fixedly connected to the lower end of the connecting block 15, and the protrusions 152 extend into the sliding groove 22. The sliding groove 22 symmetrically arranged on the upper end of the base plate 2 and the protrusions 152 at the lower end of the connecting block 15 form a sliding guide pair. After the protrusions 152 extend into the sliding groove 22, they can slide linearly along the groove, realizing the quick positioning and installation of the fixing part 1 and the base plate 2. The nested structure of the L-shaped insert block 23 and the through groove 151 of the connecting block 15 prevents the fixing part 1 from shifting in the horizontal direction through horizontal and vertical bidirectional limiting, ensuring the accuracy of the terminal fixing position. The fixing part 1 and the base plate 2 adopt a snap-fit ​​structure, which facilitates the disassembly and installation between the two and makes it easy to replace the fixing brackets of different shapes or specifications, improving the practicality of the device. The ring clamping structure composed of the upper arc ring 11 and the lower arc ring 12, combined with the elastic deformation of the inner connecting terminal 111, can adapt to inductor terminals of different diameters, solving the problem that traditional fixing bases can only adapt to a single specification.

[0019] like Figure 2 As shown, the positioning mechanism 14 includes a mounting block 141 fixedly connected to the outer wall of the upper arc-shaped ring 11, and a limiting block 142 fixedly connected to the outer wall of the lower arc-shaped ring 12. The mounting block 141 and the limiting block 142 correspond to each other. Multiple limiting holes 1421 are provided through the outer wall of the limiting block 142. Multiple positioning shafts 3 are fixedly connected to the lower outer wall of the mounting block 141, and the positioning shafts 3 correspond to the limiting holes 1421. Figure 3As shown, the lower end of the positioning shaft 3 is provided with a tapered head 31, the diameter of which is larger than that of the positioning shaft 3 at the contact end face. The lower end face of the tapered head 31 has a gradually narrowing opening 32, the diameter of the opening 32 port 1111 is linearly narrowed from bottom to top, and a pre-compressed buffer spring 33 is embedded inside the opening 32. The two ends of the buffer spring 33 are connected to the inner wall of the tapered head 31. The positioning shaft 3 on the mounting block 141 and the limiting hole 1421 on the limiting block 142 form a shaft and hole positioning pair, and the positioning shaft 3 is inserted into the limiting hole. After 1421, the coaxiality error of the upper arc ring 11 and the lower arc ring 12 is reduced, ensuring the contact consistency of the connecting terminal 111 placed in the port 1111, avoiding the risk of increased contact resistance or short circuit due to misalignment; and the tapered head 31 at the lower end of the positioning shaft 3 guides the positioning shaft 3 to quickly insert into the limiting hole 1421 through the gradually changing outer diameter, and the pre-compressed buffer spring 33 in the opening 32 can absorb the insertion impact force, avoiding rigid collision between the positioning shaft 3 and the limiting hole 1421, while realizing the limiting fixation between the fixing block 134 and the mounting block 141.

[0020] like Figure 4 As shown, the connecting mechanism 13 includes a movable block 131 fixedly connected to the outer wall of the upper arc-shaped ring 11, and a fixed block 134 fixedly connected to the outer wall of the lower arc-shaped ring 12. The upper end surface of the fixed block 134 is provided with a plurality of inwardly recessed grooves 1341. The outer wall of the front end of the fixed block 134 is provided with a second through hole 1342, which communicates with the grooves 1341. The lower end of the movable block 131 is integrally formed with a plurality of plug-in blocks 1311. The plug-in blocks 1311 extend into the grooves 1341. The outer wall of the plug-in blocks 1311 is provided with a first through hole 1312 corresponding to the second through hole 1342. The front and rear sides of the fixed block 134 are respectively provided with a threaded shaft 132 and a nut 133. The threaded shaft 132 passes through the second through hole 1342 and the first through hole 1312 and is threadedly connected to the nut 133; the insertion block 1311 of the movable block 131 and the groove 1341 of the fixed block 134 form a surface contact fit, and the upper and lower arc rings 12 are rigidly connected by the threaded shaft 132 passing through the first through hole 1312 and the second through hole 1342 and being locked with the nut 133; during disassembly, it is only necessary to loosen the nut 133 to separate them, and the upper arc ring 11 and the lower arc ring 12 can be rotated and opened between them through the connecting mechanism 13.

[0021] like Figure 2 As shown, a positioning hole 1521 is provided through the outer wall of the protrusion 152; as Figure 5 As shown, the inner wall of the base plate 2 is provided with a stretching groove 24, which communicates with the sliding groove 22. Stretching mechanisms 5 are provided on both the left and right sides of the base plate 2, and the stretching mechanisms 5 extend through the outer wall of the base plate 2 into the stretching groove 24. Figure 6As shown, the tensioning mechanism 5 consists of a pull block 51 disposed outside the base plate 2. A tensioning shaft 52 is rigidly connected to the side of the pull block 51 near the base plate 2. The tensioning shaft 52 passes through the base plate 2 along a tensioning groove 24 and extends its end into a sliding groove 22 inside the base plate 2. A slidingly fitted tensioning block 54 is fixedly connected to the outer wall of the tensioning shaft 52 inside the tensioning groove 24; the cross-sectional shapes of the two are matched. A tension spring 53 is coaxially sleeved on the outer wall of the tensioning shaft 52. One end of the tension spring 53 abuts against the end face of the tensioning block 54 facing the inside of the tensioning groove 24, and the other end is fixedly connected to the inner wall of the tensioning groove 24 away from the sliding groove 22. The positioning hole 1521 on the outer wall of the protrusion 152 allows it to be connected to the base plate. The positioning pins in the 2-slide groove 22 cooperate to form a dual positioning of sliding of the protrusion 152 and locking of the positioning hole 1521, which further improves the positional accuracy of the fixing part 1 and meets the high positioning requirements of inductor assembly; and the pull block 51, pull shaft 52, and pull block 54 transmission chain of the stretching mechanism 5, with the pull shaft 52 and the stretch groove 24 in clearance fit, can temporarily expand the width of the slide groove 22 to accommodate the protrusion 152 by pulling the pull block 51 outward to compress the stretching spring 53; after the external force is removed, the elastic restoring force of the stretching spring 53 drives the stretching shaft 52 to reset, so that the stretching shaft 52 extends into the positioning hole 1521 to fix the protrusion 152, which not only ensures the stability of the fixing part 1 installation, but also reduces the manual operation force and adapts to the rapid clamping requirements of automated production lines.
