Description

Technical Field

[0001] This utility model relates to the field of inductor coil technology, and in particular to inductor coil bobbins. Background Technology

[0002] In the production process of inductor coils, in order to ensure that the coils can be wound in accordance with the designed number of turns and arrangement, workers usually use an inductor coil frame as a winding carrier for the enameled wire to ensure the stability of the coil structure. Existing inductor coil frames usually consist of a coil frame body and wire grooves.

[0003] For example, the utility model application with application number CN202322323758.6 discloses an inductor coil frame. Specifically, this utility model includes a card holder, and a locking mechanism is provided on one side of the card holder. This utility model, by setting the locking mechanism, including a sliding groove, a card slot, and an installation groove, can effectively fix the inductor wire, which is beneficial for subsequent winding operations. In addition, during the winding operation, one end of the inductor wire needs to be placed in the groove of the movable plate first, and then the threaded rod needs to be rotated to cause the threaded rod to descend, thereby clamping the inductor wire. This method can quickly and effectively clamp the inductor wire. When the external winding device is started and the frame rotates, in order to avoid the frame rotating too fast or the wire unwinding speed being too slow, which would cause the electromagnetic wire to break during winding, a spring can effectively form a movable area, which can be floated and adjusted, thereby ensuring good tension and preventing the inductor wire from breaking.

[0004] However, in terms of traditional inductor coil frames, after the wire is wound, in order to prevent the end of the wire from detaching from the wire slot and causing a change in the number of turns of the coil, the workers usually need to apply glue to the wire end to the frame after putting the wire end into the wire slot. The operation is cumbersome, and the glue curing process also requires extra time, which reduces the production efficiency of inductor coils and makes them inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides an inductor coil frame, which has a limiting wedge block that can quickly fix the end of the wire. After the wire is wound, the second fixing knob can be rotated to drive the second threaded rod to rotate. As the second threaded rod rotates, the guide slide moves. As the guide slide moves, the sliding seat moves. As the sliding seat moves, the fixing groove fixes the beginning and end of the wire, preventing the beginning and end of the wire from loosening during use.

[0006] This utility model provides an inductor coil frame, specifically including: a first coil frame; a second coil frame slidably connected to the right side of the first coil frame; the second coil frame and the first coil frame are aligned; a wire groove is provided on the outside of both the first and second coil frames; the two wire grooves are aligned with each other; a sliding seat is slidably connected inside both the first and second coil frames; the two sliding seats are respectively aligned with the positions of the two wire grooves; a limiting slide plate is slidably connected inside each of the two sliding seats; a limiting wedge is fixedly connected to the inner side of each of the two limiting slide plates; the two limiting wedges are slidably connected inside the two sliding seats.

[0007] Optionally, two first threaded rods are symmetrically rotatably connected inside the first coil frame; a first fixing knob is coaxially fixedly connected to the left side of each of the two first threaded rods; two threaded grooves are symmetrically opened on the left side of the second coil frame; the right sides of the two first threaded rods are respectively threaded into the two threaded grooves.

[0008] Optionally, a set of fixing springs is fixedly connected to the outer side of each limiting slide plate; the ends of the two sets of fixing springs are respectively fixedly connected to the two sliding seats; a damping block is fixedly connected to the center of each outer side of the limiting slide plate; the two damping blocks are respectively arranged inside the two sets of fixing springs; the ends of the two damping blocks are respectively fixedly connected to the two sliding seats; the two damping blocks are both cylindrical structures made of ethylene propylene rubber.

[0009] Optionally, a guide slide is fixedly connected to the outside of each of the two sliding seats; the two guide slides are slidably connected inside the first coil frame and the second coil frame, respectively; a second threaded rod is rotatably connected inside the upper part of the first coil frame and the upper part of the second coil frame; a second fixing knob is coaxially fixedly connected to the top surface of each of the two second threaded rods; the two guide slides are threadedly connected to the outside of the two second threaded rods, respectively.

[0010] Optionally, a fixing groove is provided on the bottom end face of each of the two limiting wedges; both fixing grooves are arc-shaped groove structures; the two fixing grooves are respectively aligned with the positions of the two wire grooves.

[0011] Optionally, an auxiliary soft pad is fixedly connected to the bottom end face of each of the two fixing grooves; the auxiliary soft pad is an arc-shaped structure made of nitrile rubber.

[0012] Beneficial effects

[0013] When the wire is wound, the present invention allows the first threaded rod to slide within the first coil frame by rotating the first fixed knob, thereby adjusting the distance between the first and second coil frames. This facilitates the adjustment of the length of the inductor coil frame according to the required amount of wire to be wound, effectively improving the versatility of the inductor coil frame and making it more convenient to use.

[0014] When winding the wire, simply place the first end of the wire into the wire groove, allowing it to press against the limiting wedge. After the first end enters the wire groove, the limiting wedge returns to its original position with the rebound of the fixing spring, blocking the wire groove and preventing the first end of the wire from coming out. Only then can the wire be wound. After winding, the second fixing knob can be turned to move the second threaded rod through the guide slide to move the sliding seat, fixing the first and second ends of the wire in place. This prevents the first and second ends of the wire from loosening during use, eliminating the need for gluing or wrapping the wire during winding. The operation is simple and quick, effectively improving the convenience of the inductor coil frame and making it more convenient to use. Attached Figure Description

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0027] Example 1:

[0028] This utility model proposes an inductor coil frame; please refer to [reference needed]. Figures 1 to 7 It includes: a first coil frame 1;

[0029] A second coil frame 101 is slidably connected to the right side of the first coil frame 1; the second coil frame 101 is aligned with the first coil frame 1; a wire groove 105 is provided on the outside of both the first coil frame 1 and the second coil frame 101; the two wire grooves 105 are aligned with each other; a sliding seat 108 is slidably connected inside both the first coil frame 1 and the second coil frame 101; the two sliding seats 108 are aligned with the two wire grooves 105 respectively; a limiting slide plate 111 is slidably connected inside each of the two sliding seats 108; a limiting wedge 110 is fixedly connected to the inner side of each of the two limiting slide plates 111; the two limiting wedges 110 are slidably connected inside the two sliding seats 108 respectively.

[0030] Two first threaded rods 103 are symmetrically rotatably connected inside the first coil frame 1; a first fixing knob 104 is coaxially fixedly connected to the left side of each of the two first threaded rods 103; two threaded grooves 102 are symmetrically opened on the left side of the second coil frame 101; the right sides of the two first threaded rods 103 are respectively threaded into the two threaded grooves 102.

[0031] A set of fixing springs 112 is fixedly connected to the outer side of the limiting slide plate 111; the ends of the two sets of fixing springs 112 are respectively fixedly connected to the two sliding seats 108; a damping block 113 is fixedly connected to the center of the outer side of the limiting slide plate 111; the two damping blocks 113 are respectively set inside the two sets of fixing springs 112; the ends of the two damping blocks 113 are respectively fixedly connected to the two sliding seats 108; the two damping blocks 113 are both cylindrical structures made of ethylene propylene rubber.

[0032] A guide slide plate 109 is fixedly connected to the outside of each of the two sliding seats 108; the two guide slide plates 109 are slidably connected to the inside of the first coil frame 1 and the second coil frame 101 respectively; a second threaded rod 106 is rotatably connected to the upper part of the first coil frame 1 and the upper part of the second coil frame 101 respectively; a second fixing knob 107 is coaxially fixedly connected to the top surface of each of the two second threaded rods 106; the two guide slide plates 109 are threadedly connected to the outside of the two second threaded rods 106 respectively.

[0033] Each of the two limiting wedges 110 has a fixing groove 114 on its bottom end face; both fixing grooves 114 are arc-shaped groove structures; the two fixing grooves 114 are respectively aligned with the positions of the two wire grooves 105.

[0034] The specific usage and function of this embodiment are as follows: By rotating the first fixed knob 104, the first fixed knob 104 drives the first threaded rod 103 to rotate. During the rotation of the first threaded rod 103, the second coil frame 101 will slide within the first coil frame 1. As the second coil frame 101 slides, the distance between the first coil frame 1 and the second coil frame 101 will be adjusted, which facilitates the adjustment of the length of the inductor coil frame according to the required winding wire. When winding the wire, simply place the first end of the wire into the wire groove 105. During the process of placing the first end of the wire into the wire groove 105, the limiting wedge 110 will be squeezed, causing the limiting wedge 110 to slide within the sliding seat 108 and the limiting slide plate 111 to slide within the sliding seat 108. As the limiting slide plate 111 slides, it will squeeze the fixing spring 112. The damping block 113 dampens the fixing spring 112, allowing the first end of the wire to enter the wire groove. After the wire is inserted into the guide groove 105, the limiting wedge 110 loses pressure on the beginning of the wire. At this time, the limiting wedge 110 will return to its original position with the rebound of the fixing spring 112, so that the limiting wedge 110 blocks the guide groove 105, preventing the beginning of the wire from coming out of the guide groove 105. Only then can the wire be coiled. After coiling, the end of the wire is placed into another guide groove 105, and the above movement is reversed, so that the end of the wire cannot come out of the guide groove 105 either. After the wire is coiled, the second fixing knob 107 can be rotated to drive the second threaded rod 106 to rotate. As the second threaded rod 106 rotates, the guide slide 109 moves. As the guide slide 109 moves, the sliding seat 108 moves. As the sliding seat 108 moves, the fixing groove 114 fixes the beginning and end of the wire, preventing the beginning and end of the wire from loosening during use.

[0035] Example 2:

[0036] Based on Example 1, please refer to Figure 7 It includes: an auxiliary soft pad 115, with an auxiliary soft pad 115 fixedly connected to the bottom end face of each of the two fixing grooves 114; the auxiliary soft pad 115 is an arc-shaped structure made of nitrile rubber.

[0037] The specific usage and function of this embodiment: By setting the auxiliary soft pad 115, the fit between the fixing groove 114 and the thread can be improved, and the rigid pressure of the limiting wedge 110 can be offset to avoid the thread from being indented.
