Description

Technical Field

[0001] This utility model relates to the field of current sensor installation technology, and in particular to a current sensor installation structure. Background Technology

[0002] As a core component for accurately acquiring current signals, current sensors are widely used in industrial automated production lines, new energy vehicle power systems, power system power distribution equipment, rail transit traction systems, and other fields. Their operational stability directly determines the operating accuracy and safety performance of the entire equipment.

[0003] In existing technologies, the mounting structures of some current sensors lack vibration damping performance. The mounting brackets are mostly rigid metal connections. When applied to industrial equipment vibration environments, such as motor control cabinets and automobile chassis circuits, vibrations are easily transmitted to the inside of the sensor, causing the current detection data to drift and increasing the detection error. The fixing and disassembly efficiency is low, relying on bolt tightening. Disassembly and assembly require the use of special tools such as wrenches, which is time-consuming. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor shock absorption and long disassembly time in the existing technology, and to propose a current sensor mounting structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a current sensor mounting structure, including a mounting base, a connecting seat, and a current sensor body.

[0006] The bottom of the connecting seat is fixedly connected to the bottom of the mounting base plate. A shock-absorbing plate is provided on the top of the connecting seat. The current sensor body is located on the top of the shock-absorbing plate. Fixed frames are fixedly connected to both inner walls of the connecting seat. A lead screw is provided inside each fixed frame. One end of the lead screw is rotatably connected to one inner wall of the fixed frame. An adjusting plate is fixedly connected to the other end of the lead screw. A buffer assembly is threadedly connected to the outer surface of the lead screw. Fixed structures are threadedly connected to both outer surfaces of the connecting seat.

[0007] The buffer assembly includes a movable rod threadedly connected to the outer surface of the lead screw, a buffer spring fixedly connected to one side of the outer surface of the movable rod, and a buffer plate fixedly connected to the end of the buffer spring away from the movable rod.

[0008] Furthermore, the fixing structure includes a screw threaded through to the side of the connector, with a plug rotatably connected to one end of the screw near the current sensor body, and a rotating block fixedly connected to the other end of the screw.

[0009] Furthermore, a base is fixedly connected to the bottom of the current sensor body, and connecting grooves are provided on both outer surfaces of the base.

[0010] Furthermore, the insert block and the connecting groove cooperate with each other, and a slider is fixedly connected to the bottom of the insert block.

[0011] Furthermore, rectangular grooves are provided at both ends of the top of the damping plate, and the insert block is slidably connected to the rectangular grooves.

[0012] Furthermore, the top of the damping plate is provided with a connection hole, and the bottom of the damping plate is fixedly connected with a damping column.

[0013] Furthermore, the buffer assembly has two sets distributed symmetrically on the outer surface of the lead screw.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the setting of shock-absorbing plate and buffer assembly realizes bidirectional shock absorption, solves the vibration interference problem of traditional installation structure, and reduces the direct impact of vibration on the sensor; at the same time, rotating the adjustment plate drives the lead screw to rotate, which can adjust the lateral position of the moving rod, so that the buffer plate fits against the side wall of the current sensor body, which is suitable for installing current sensors of different sizes.

[0015] 2. In this utility model, the fixed structure and the base connecting groove enable quick fixing and disassembly, improving maintenance efficiency. Rotating the rotating block with anti-slip texture drives the screw to extend and retract. The insert block moves smoothly under the guidance of the slider and the rectangular groove, and finally snaps into the connecting groove of the base to complete the fixing without the need for special tools. When disassembling, rotating the rotating block in the opposite direction releases the sensor. The disassembly and assembly time of a single sensor is shortened, and maintenance time and cost are greatly reduced. Attached Figure Description

[0018] Please see Figure 1-5 This utility model provides a technical solution: a current sensor mounting structure, including a mounting base 1, a connecting seat 2, and a current sensor body 3.

[0019] The bottom of the connecting seat 2 is fixedly connected to the bottom of the mounting base plate 1. The top of the connecting seat 2 is provided with a shock-absorbing plate 4. The current sensor body 3 is located on the top of the shock-absorbing plate 4. The inner walls on both sides of the connecting seat 2 are fixedly connected with a fixing frame 5. The inside of the fixing frame 5 is provided with a lead screw 51. One end of the lead screw 51 is rotatably connected to one side of the inner wall of the fixing frame 5. The other end of the lead screw 51 is fixedly connected with an adjusting plate 52. The outer surface of the lead screw 51 is threadedly connected with a buffer assembly 6. The outer surfaces on both sides of the connecting seat 2 are threadedly connected with a fixing structure 7.

[0020] The specific settings and functions of its buffer component 6 and fixing structure 7 will be discussed below.

[0021] In this embodiment: the buffer assembly 6 includes a moving rod 61 threadedly connected to the outer surface of the lead screw 51, a buffer spring 62 fixedly connected to one side of the outer surface of the moving rod 61, and a buffer plate 63 fixedly connected to the end of the buffer spring 62 away from the moving rod 61.

[0022] The effect achieved by the above components is as follows: the rotating adjustment disk 52 drives the lead screw 51 to rotate, causing the moving rod 61 to move along the axial direction of the lead screw 51, thereby pushing the buffer plate 63 to fit against the side wall of the current sensor body 3; the buffer spring 62 can absorb lateral vibration through elastic deformation.

[0023] Specifically, the fixing structure 7 includes a screw 71 threaded through and connected to the side of the connecting seat 2. One end of the screw 71 near the current sensor body 3 is rotatably connected to an insert 72, and the other end of the screw 71 is fixedly connected to a rotating block 73.

[0024] The effect achieved by the above components is as follows: when the rotating block 73 is manually rotated, the screw 71 moves axially along the internal thread hole of the connecting seat 2, causing the insert 72 to move closer to or away from the sensor base 31; the setting of the thrust bearing can prevent the insert 72 from rotating synchronously with the screw 71, ensuring that the insert 72 only makes linear motion, and can be quickly tightened without tools.

[0025] Specifically, a base 31 is fixedly connected to the bottom of the current sensor body 3, and connecting grooves 32 are provided on both outer surfaces of the base 31.

[0026] The effect achieved by the above components is that the base 31 can increase the contact area between the sensor and the shock-absorbing plate 4, thereby improving the stability of placement.

[0027] Specifically, the insert 72 and the connecting groove 32 cooperate with each other, and the bottom of the insert 72 is fixedly connected to the slider 74.

[0028] The effect achieved by the above components is that when the connecting groove 32 and the insert block 72 are engaged, a "wedge lock" can be formed to prevent the sensor from falling off in the vertical direction.

[0029] Specifically, both ends of the top of the damping plate 4 are provided with rectangular grooves 41, and the insert block 72 is slidably connected to the rectangular grooves 41.

[0030] The effect achieved by the above components is that the cooperation between the slider 74 and the rectangular groove 41 can limit the movement trajectory of the insert 72, ensuring that the insert 72 moves only in the horizontal direction, avoiding misalignment of the connecting groove 32 due to the offset of the insert 72, and ensuring the accuracy of locking.

[0031] Specifically, the top of the damping plate 4 is provided with a connection hole, and the bottom of the damping plate 4 is fixedly connected with a damping column 42.

[0032] The above components achieve the following effects: the connection hole can avoid the sensor's wiring terminals, preventing interference with the damping plate 4 during wiring, and at the same time, it plays a positioning role for the terminals, ensuring that the terminals do not shift when the wires are connected; the damping column 42 has excellent elastic recovery and aging resistance, and can absorb vertical vibration energy.

[0033] Specifically, the buffer assembly 6 has two sets distributed symmetrically on the outer surface of the lead screw 51.

[0034] The effects achieved by the above components are as follows: the symmetrically distributed buffer components 6 can provide lateral buffering force from both sides of the sensor at the same time, avoiding sensor tilting caused by a single buffer point; the setting of two sets of buffer springs 62 can make the buffering force evenly transmitted to the side wall of the sensor, preventing excessive local force from causing deformation of the shell.

[0035] Working principle: First, the current sensor body 3 is placed on top of the shock-absorbing plate 4 via the base 31 fixed at the bottom. The rotating block 73 of the fixing structure 7 is manually rotated, which drives the screw 71 to move axially along the internal thread hole of the connecting seat 2. The end of the screw 71 near the sensor pushes the plug 72 to move. At this time, the slider 74 at the bottom of the plug 72 slides along the rectangular groove 41 of the shock-absorbing plate 4. The rectangular groove 41 restricts the plug 72 to only move horizontally, preventing the plug 72 from shifting and causing misalignment with the connecting groove 32 of the base 31. Finally, the plug 72 is accurately embedded into the connecting groove 32, forming a "wedge locking" structure, which realizes quick fixing and disassembly, and improves maintenance efficiency. The rotating adjustment disk 52 drives the lead screw 51 to rotate around the inner wall of the fixed frame 5. Since the moving rod 61 is threadedly connected to the lead screw 51, when the lead screw 51 rotates, it will drive the moving rod 61 to move along the axial direction of the lead screw 51, thereby pushing the buffer plate 63 on one side of the moving rod 61 to gradually fit against the side wall of the current sensor body 3. When the equipment generates vertical vibration during operation, the damping column 42 at the bottom of the damping plate 4, with its excellent elastic recovery and aging resistance, quickly absorbs the vertical vibration energy, solves the vibration interference problem of traditional installation structures, and reduces the direct impact of vibration on the sensor.
