Description

Technical Field

[0001] This utility model relates to the field of inductor technology, specifically to a novel rod-shaped inductor. Background Technology

[0002] With the rapid miniaturization and integration of electronic devices, various power systems are placing higher demands on the size, performance, and compatibility of components. Rod inductors, with their compact structure and high energy density, have become an indispensable key component in electronic devices, widely used in communication equipment, consumer electronics, automotive electronics, and other electronic circuits.

[0003] In existing technologies, rod-shaped inductors are typically installed inside electronic components. When an electronic component is subjected to external vibration, the rod-shaped inductor inside it will simultaneously bear the vibration impact. Due to the lack of corresponding reinforcement structures, the rod-shaped inductor cannot effectively offset the relative displacement trend caused by vibration. This results in the pin solder joint of the connector continuously bearing stress concentration caused by vibration. This stress concentration will gradually weaken the structural strength of the solder joint, which can easily lead to problems such as loosening, desoldering, or even breakage of the solder joint. This not only seriously affects the structural stability of the pin connection, but also significantly shortens the service life of the rod-shaped inductor and even the entire electronic component.

[0004] Therefore, we propose a novel rod-shaped inductor to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a novel rod-shaped inductor to solve the problem mentioned in the background art that rod-shaped inductors cannot effectively counteract the relative displacement trend caused by external vibration when electronic components are subjected to external vibration, resulting in stress concentration at the solder joint of the connector pins, which in turn leads to loosening, desoldering, or even breakage of the solder joint.

[0006] This utility model provides the following technical solution: A novel rod-shaped inductor includes a base, a rod inductor mounted on the top surface of the base, a first protective cover fixedly connected to the base, a second protective cover detachably mounted on one end of the first protective cover, a connecting assembly between the first and second protective covers, a mounting plate fixedly connected to the bottom end of the base, a terminal block mounted on the mounting plate, a support plate fixedly connected to the end of the mounting plate away from the base, a reinforcing assembly provided on the support plate, the reinforcing assembly including a sliding block slidably connected to the inner wall of the support plate, a connecting frame fixedly connected to the sliding block, a plurality of second springs fixedly connected to the inner wall of the connecting frame, and a pressure plate fixedly connected to the end of each of the plurality of second springs away from the connecting frame.

[0007] Preferably, the connecting assembly includes a support plate fixedly connected to the first protective cover and the second protective cover. There are two support plates, one of which has a threaded rod threadedly connected to its side wall. One end of the threaded rod is fixedly connected to a handle, and the other end of the threaded rod is rotatably sleeved with a movable plate. Multiple L-shaped blocks are fixedly connected to the movable plate, and multiple rectangular grooves are formed on the support plate.

[0008] Preferably, a plurality of rectangular blocks are fixedly connected to the bottom end of another support plate, and each of the rectangular blocks has a through groove, and the rectangular blocks are inserted into the rectangular grooves.

[0009] Preferably, a fixing plate is fixedly connected to the side wall of the support plate, a limit rod is slidably connected to the fixing plate, and a pull ring is fixedly connected to the top end of the limit rod.

[0010] Preferably, the outer ring of the limiting rod is fitted with a first spring, one end of the first spring is fixedly connected to the fixing plate, and the other end of the first spring is fixedly connected to the pull ring.

[0011] Preferably, a limiting block is fixedly connected to the side wall of the sliding block, a limiting hole is provided on the limiting block, and the limiting rod is inserted into the limiting hole.

[0012] This utility model has the following beneficial effects: 1. The rod sensor can be unlocked by pulling the pull ring, and the sliding block can be fixed by releasing the pull ring after the sliding block is adjusted. The entire reinforcement operation does not require complicated tools. When the rod sensor is subjected to vibration, the second spring can dynamically buffer the vibration energy through elastic deformation, offset the relative displacement trend, reduce the loosening and breakage caused by stress concentration at the welding point, and significantly improve the structural stability and service life of the pin connection.

[0013] 2. During installation, the sensor is initially positioned by inserting the rectangular block into the rectangular slot. A secure connection is achieved by rotating the handle to allow the L-shaped block to embed into the slot. For disassembly, rotating the handle in the opposite direction to unlock the sensor and gently pulling it apart will separate the protective cover. The entire process requires no complex tools, and the operation is simple and intuitive, significantly reducing installation and maintenance time. Attached Figure Description

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

[0021] This embodiment aims to address the problem of loosening, wear, or even breakage at the solder joint between the connector 51 and the circuit pins in practical applications of rod inductors due to vibrations in the working environment. Please refer to [link to relevant documentation]. Figure 1 , Figure 4 - Figure 5A novel rod-shaped inductor includes a base 1, a rod inductor 2 mounted on the top surface of the base 1, a mounting plate 5 fixedly connected to the bottom end of the base 1, a terminal block 51 mounted on the mounting plate 5, and a support plate 6 fixedly connected to the end of the mounting plate 5 away from the base 1. The support plate 6 is provided with a reinforcing component 7, which includes a sliding block 75 slidably connected to the inner wall of the support plate 6. The sliding engagement between the sliding block 75 and the support plate 6 adopts a clearance fit design, ensuring smooth sliding while reducing the wobble of the sliding block 75 itself, thus ensuring the stability of the force exerted by the pressure plate 710 on the weld joint. A limiting block 76 is fixedly connected to the side wall of the moving block 75. A limiting hole 77 is opened on the limiting block 76. The limiting rod 72 is inserted into the limiting hole 77. A connecting frame 78 is fixedly connected to the sliding block 75. Multiple second springs 79 are fixedly connected to the inner wall of the connecting frame 78. A pressure plate 710 is fixedly connected to the end of the multiple second springs 79 away from the connecting frame 78. The contact surface between the pressure plate 710 and the welding point is bonded to a silicone pad. The silicone pad has insulation and buffering properties, which can not only avoid the risk of short circuit caused by direct contact between the metal pressure plate 710 and the pin, but also further enhance the buffering effect against vibration.

[0022] A fixing plate 71 is fixedly connected to the side wall of the support plate 6. A limit rod 72 is slidably connected to the fixing plate 71. A pull ring 73 is fixedly connected to the top of the limit rod 72. A first spring 74 is sleeved on the outer ring of the limit rod 72. One end of the first spring 74 is fixedly connected to the fixing plate 71, and the other end of the first spring 74 is fixedly connected to the pull ring 73. The first spring 74 needs to be selected according to the actual situation. Its elastic coefficient has been calibrated to ensure that it can provide sufficient restoring force to allow the limit rod 72 to be reliably inserted into the limit hole 77, but without causing the operator to have to exert too much force when pulling the pull ring 73 due to excessive elasticity.

[0023] The fixed plate 71, the limiting block 76, the sliding block 75, the limiting rod 72, and the first spring 74 are all symmetrically arranged, so that the limiting block 76 is subjected to uniform force when it drives the sliding block 75 and the connecting frame 78 to move, thus avoiding tilting caused by force on one side.

[0024] In this embodiment: after the terminal 51 on the rod sensor 2 is installed with the pin and the line, the operator first pulls the pull ring 73 upward. The pull ring 73 then drives the limit rod 72 to slide vertically upward along the fixed plate 71. At this time, the first spring 74 sleeved on the outer ring of the limit rod 72 is stretched synchronously and accumulates elastic potential energy. The bottom end of the limit rod 72 then completely disengages from the corresponding limit groove on the side wall of the support plate 6, thereby releasing the locking state of the sliding block 75.

[0025] Next, the operator can push the limiting block 76, which, through the rigid connection between the limiting block 76 and the sliding block 75, causes the sliding block 75 to slide smoothly in the slide rail on the inner wall of the support plate 6. The displacement of the sliding block 75 is synchronously transmitted to the connecting frame 78 fixed thereto, thereby causing the overall structure consisting of the connecting frame 78, the second spring 79, and the pressure plate 710 to move synchronously. When the pressure plate 710 is precisely aligned with the pin welding point of the connector 51, the pushing action is stopped and the pull ring 73 is released. The first spring 74 immediately releases its stored elastic potential energy, pulling the pull ring 73 and the limiting rod 72 vertically downward to reset. The bottom end of the limiting rod 72 is precisely embedded in the limiting hole 77 of the limiting block 76 on the side wall of the sliding block 75, thereby indirectly fixing the sliding block 75 by locking the limiting block 76.

[0026] At this time, the second spring 79 on the inner wall of the connector 78 is in a pre-compressed state, and its elastic force pushes the pressure plate 710 to fit tightly against the pin welding joint, forming a continuous and stable clamping force. This clamping force can effectively counteract the relative displacement tendency caused by vibration, avoid wear or stress concentration at the welding joint due to repeated friction, and ultimately achieve real-time dynamic reinforcement and protection of the pin-to-circuit connection. Example

[0027] This embodiment aims to address the problems of cumbersome disassembly and assembly of the protective cover for rod-shaped inductors and the inadequate protection for the rod inductor 2. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 - Figure 3 A novel rod-shaped inductor includes a base 1, a first protective cover 3 fixedly connected to the base 1, a second protective cover 31 detachably installed on the end side of the first protective cover 3, and a connecting assembly 4 between the first protective cover 3 and the second protective cover 31. The connecting assembly 4 includes a support plate 41 fixedly connected to the first protective cover 3 and the second protective cover 31. There are two support plates 41. One of the support plates 41 has a threaded rod 42 threadedly connected to the side wall. One end of the threaded rod 42 is fixedly connected to a handle 43, and the other end of the threaded rod 42 is rotatably sleeved with a movable plate 44. Multiple L-shaped blocks 45 are fixedly connected to the movable plate 44, and multiple rectangular slots 47 are opened on the support plate 41.

[0028] Another support plate 41 has multiple rectangular blocks 46 fixedly connected to its bottom end. Each rectangular block 46 has a through groove 48, and the rectangular blocks 46 are inserted into the rectangular grooves 47.

[0029] In this embodiment: When installing the protective cover, the second protective cover 31 is first moved closer to the first protective cover 3, so that the multiple rectangular blocks 46 at the bottom of the support plate 41 of the second protective cover 31 are aligned with the corresponding rectangular grooves 47 of the support plate 41 of the first protective cover 3. Then, the rectangular blocks 46 are inserted into the rectangular grooves 47. At this time, the two support plates 41 are tightly fitted, and the insertion structure of the rectangular blocks 46 and the rectangular grooves 47 forms a preliminary positioning. The relative displacement of the two in the horizontal direction is restricted by the cooperation of the groove and the block.

[0030] Next, the operator turns the handle 43. Since the threaded rod 42 is threadedly connected to one of the support plates 41, and its other end is in a rotating sleeve state with the moving plate 44, under the action of threaded transmission, the threaded rod 42 will drive the moving plate 44 to move in a straight line, thereby pushing multiple L-shaped blocks 45 on the moving plate 44 to move towards the rectangular block 46 simultaneously. When the L-shaped block 45 is precisely embedded in the through groove 48 of the rectangular block 46, the L-shaped block 45 and the rectangular block 46 form a relative constraint. The horizontal part of the L-shaped block 45 is stuck on the edge of the through groove 48, and the vertical part is in contact with the inner wall of the through groove 48. Combined with the clamping state of the rectangular block 46 in the rectangular groove 47, the two support plates 41 are connected. At this time, the first protective cover 3 and the second protective cover 31 are firmly connected by the connecting component 4 to form a complete and closed protective space, which tightly wraps the rod sensor 2. When the protective cover needs to be disassembled for inspection or maintenance, turn the handle 43 in the reverse direction. Under the reaction force of the threaded rod 42, the moving plate 44 moves away from the rectangular block 46. The L-shaped block 45 then completely exits from the through slot 48 of the rectangular block 46, releasing the locking restriction on the rectangular block 46. At this time, simply pull the second protective cover 31 gently to pull the rectangular block 46 out of the rectangular slot 47, achieving quick separation of the second protective cover 31 from the first protective cover 3.
