Description

Technical Field

[0001] This utility model relates to the field of Hall current sensors, and in particular to the shock-resistant structure of Hall current sensors. Background Technology

[0002] A Hall current sensor is a current measuring device based on the Hall effect principle. It is mainly used to detect and measure the magnitude of current. It converts the magnetic field generated by the current into a voltage signal, thereby realizing non-contact measurement of the current.

[0003] Existing Hall current sensors lack effective shock-resistant structures during use. When subjected to external impacts or vibrations, internal components are easily loosened or damaged, which can even affect measurement accuracy. The core components of Hall current sensors are quite sensitive to mechanical shocks. Once subjected to strong vibrations, the magnetic core may shift or the Hall element may fail, affecting the normal operation of the sensor.

[0004] Therefore, in view of the problem that the existing Hall current sensors lack a shock-resistant structure and are easily damaged by external impacts, there is an urgent need to design a new type of shock-resistant structure for Hall current sensors. Utility Model Content

[0005] To overcome the problem that existing Hall current sensors lack shock-resistant structures and are easily damaged by external impacts.

[0006] The technical solution of this utility model is as follows: a Hall current sensor anti-vibration structure, including a sensor body; and also including a fixing ring, positioning screws, collar, elastic rope, fixing plate, and outer protective shell. Fixing rings are provided on both the left and right sides of the outer surface of the sensor body. Eight circumferentially distributed positioning screws are connected to the outer surface of the fixing rings. A collar is fitted on the outer surface of the positioning screws. One end of an elastic rope is connected to both the left and right sides of the outer surface of the collar. The other end of the elastic rope is connected to a fixing plate. An outer protective shell is installed on the outside of the multiple fixing plates.

[0007] Preferably, by setting positioning screws, the sensor body is placed inside the outer protective shell during installation. Then, the collar is fitted onto the outer surface of the positioning screw, and the positioning screw is connected to the fixing ring. The eight sets of elastic ropes are stretched, so that the sensor body is in a suspended state inside the outer protective shell. The shock-resistant effect is achieved through the soft connection of the elastic ropes, thereby solving the problem that existing Hall current sensors lack shock-resistant structures and are easily damaged by external impacts.

[0008] Preferably, a fixing sleeve is connected to the left side of the outer surface of the outer protective shell, and an adjusting screw is threaded through both the upper and lower sides of the outer surface of the fixing sleeve. A connecting seat is rotatably connected to the end of the adjusting screw near the sensor body, and a clamp is installed on the bottom surface of the connecting seat.

[0009] Preferably, the inner surface of the fixing sleeve and the outer surface of the outer protective shell are both machined with connecting threads on the left side.

[0010] Preferably, the inner surface of the fixed sleeve is connected to two symmetrical limiting rods on the upper and lower sides, and the clamping plate and the limiting rods are slidably connected through each other.

[0011] Preferably, anti-slip pads are provided on the side of both clamps away from the corresponding adjusting screw, and the anti-slip pads are bonded to the clamps with adhesive.

[0012] Preferably, a knob is provided at the end of each of the two adjusting screws furthest from the corresponding clamp.

[0013] Preferably, the fixing plate is fixed to the outer protective shell with screws.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting positioning screws, the sensor body is placed inside the outer protective shell during installation. Then, the collar is fitted onto the outer surface of the positioning screws, and the positioning screws are connected to the fixing ring. The eight sets of elastic ropes will be stretched, so that the sensor body is in a suspended state inside the outer protective shell. The elastic ropes achieve a shock-resistant effect through soft connection, thereby solving the problem that existing Hall current sensors lack a shock-resistant structure and are easily damaged by external impacts.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a Hall current sensor anti-vibration structure, including a sensor body 1; it also includes a fixing ring 2, positioning screws 3, collars 4, elastic ropes 5, fixing plates 6, and an outer protective shell 7. Fixing rings 2 are provided on both the left and right sides of the outer surface of the sensor body 1. Eight circumferentially distributed positioning screws 3 are connected to the outer surface of the fixing rings 2. A collar 4 is fitted onto the outer surface of the positioning screws 3. One end of an elastic rope 5 is connected to each of the left and right sides of the outer surface of the collar 4. The other end of the elastic rope 5 is connected to the fixing plate 6. An outer protective shell 7 is installed on the outer side of the multiple fixing plates 6. By setting the positioning screws 3, the sensor body 1 is placed inside the outer protective shell 7 during installation. Then, the collar 4 is fitted onto the outer surface of the positioning screws 3, and the positioning screws 3 are connected to the fixing rings 2. The eight sets of elastic ropes 5 are stretched, thereby making the sensor body 1 suspended inside the outer protective shell 7. The anti-vibration effect is achieved through the soft connection of the elastic ropes 5.

[0024] Please see Figures 1-5 In this embodiment, a fixing sleeve 8 is connected to the left side of the outer surface of the outer protective shell 7. An adjusting screw 10 is threaded through both the upper and lower sides of the outer surface of the fixing sleeve 8. A connecting seat 11 is rotatably connected to the end of the adjusting screw 10 near the sensor body 1. A clamping plate 12 is installed on the bottom surface of the connecting seat 11. By setting the adjusting screw 10, the clamping plate 12 can be moved up and down when the adjusting screw 10 is rotated, thereby clamping the cable of the sensor body 1 and improving the fixing strength of the cable. The inner surface of the fixing sleeve 8 and the outer surface of the outer protective shell 7 are both machined with connecting threads 9 on the left side. By setting the connecting threads 9, it is easy to disassemble and assemble the fixing sleeve 8, thereby installing the internal structure of the outer protective shell 7. Two symmetrical limiting rods 13 are connected to the upper and lower sides of the inner surface of the fixing sleeve 8. The clamping plate 12 is slidably connected to the limiting rods 13. By setting the limiting rods 13, the movement direction of the clamping plate 12 can be restricted, avoiding the problem that the adjusting screw 10 causes the clamping plate 12 to rotate and cannot accurately clamp the cable.

[0025] Please see Figures 1-5In this embodiment, anti-slip pads 14 are provided on the side surface of the two clamping plates 12 away from the corresponding adjusting screws 10. The anti-slip pads 14 are glued to the clamping plates 12. By providing anti-slip pads 14, the friction between the clamping plates and the cable can be increased, thereby improving the anti-detachment effect. A knob 15 is provided on the end of the two adjusting screws 10 away from the corresponding clamping plates 12. By providing knobs 15, it is easy for the operator to rotate the adjusting screws 10, thereby improving the ease of operation. The fixing plate 6 and the outer protective shell 7 are fixed together by screws. By using screws to fix the fixing plate 6 and the outer protective shell 7, it is easy to disassemble and assemble, and at the same time, it has high fixing strength.

[0026] During operation, the adjusting screw 10, when rotated, drives the clamping plate 12 to move up and down, thereby clamping the cable of the sensor body 1 and improving the fixing strength of the cable. The connecting thread 9 facilitates the disassembly and assembly of the fixing sleeve 8, allowing for the installation of the internal structure of the outer protective shell 7. The limiting rod 13 restricts the movement direction of the clamping plate 12, preventing the adjusting screw 10 from causing the clamping plate 12 to rotate and thus failing to accurately clamp the cable. The anti-slip pad 14 increases the friction between the clamping plate and the cable, improving the anti-detachment effect. The knob 15 allows the operator to easily rotate the adjusting screw 10, improving operational convenience. The fixing plate 6 and the outer protective shell 7 are fixed with screws, facilitating disassembly and assembly while providing high fixing strength.

[0027] Through the above steps, by setting the positioning screw 3, the sensor body 1 is placed inside the outer protective shell 7 during installation. Then, the collar 4 is fitted onto the outer surface of the positioning screw 3. Subsequently, the positioning screw 3 is connected to the fixing ring 2, and the eight sets of elastic ropes 5 are stretched, so that the sensor body 1 is in a suspended state inside the outer protective shell 7. The vibration resistance effect is achieved through the soft connection of the elastic ropes 5, thereby solving the problem that the existing Hall current sensor lacks a vibration-resistant structure and is easily damaged by external impact.
