Description

Technical Field

[0001] The utility model relates to the technical field of current sensor installation, in particular to a current sensor assembly structure. Background Art

[0002] As an indispensable component of modern electronic equipment and systems, the main function of current sensors is to accurately detect current changes in circuits and convert them into measurable and processable signals. The assembly structure of current sensors is the key to ensuring their stable performance and reliable operation. A reasonable assembly structure can not only ensure good contact between the sensor and the circuit and reduce signal distortion, but also effectively resist interference from external environmental factors such as temperature, humidity, vibration, etc. At present, the assembly structure of current sensors has formed various types, such as welding, crimping, plug-in, etc. Each structure has its specific application scenarios and advantages. For example, the welding structure has good stability and reliability, but the operation is complicated; the plug-in structure is simple and easy, but the accuracy and stability are relatively low.

[0003] For example, the Chinese authorized patent "A Current Sensor Assembly Structure" with announcement number CN206920506U includes a first bracket for fixing multiple conductors to be measured and a second bracket for fixing multiple current sensors, wherein: the first bracket has a first fixing portion, and the second bracket has a second fixing portion; the first bracket is assembled to the second bracket by the cooperation of the first fixing portion and the second fixing portion, and when the first bracket is assembled to the second bracket, each conductor to be measured passes through the detection hole on each current sensor. The utility model assembles multiple conductors to be measured and multiple current sensors into modules respectively through the first bracket and the second bracket, and can realize many-to-many modular assembly of current sensors and conductors to be measured.

[0004] Although the above-mentioned existing technology can realize the assembly of current sensors, the assembly flexibility is poor, and it is inconvenient to install current sensors of different specifications. In addition, the assembly equipment is prone to vibration during operation, and these vibrations will affect the current sensors. Therefore, it does not meet the existing needs. In this regard, we propose a current sensor assembly structure. Utility Model Content

[0005] The utility model aims to provide a current sensor assembly structure to solve the problem that the assembly mechanism proposed in the above background technology is inconvenient to install current sensors of different specifications and has poor anti-seismic performance.

[0006] To achieve the above object, the utility model provides the following technical solution: a current sensor assembly structure, comprising a mounting frame, wherein the upper end surface of the mounting frame is provided with a movable groove; and further comprising:

[0007] An assembly plate, which is arranged inside the movable groove, and at least two assembly plates are provided, and slide grooves are provided on both sides of the assembly plate, a fixed rod is installed inside the slide groove, and both ends of the fixed rod are fixed to the assembly plate, a sliding block is installed outside the fixed rod, and the sliding block and the fixed rod are slidably limited, and a support spring is installed on one side of the sliding block, the support spring is wrapped outside the fixed rod, and both ends of the support spring are respectively fixed to the assembly plate and the sliding block;

[0008] A limiting stud is arranged on the upper end surface of the sliding block, the bottom of the limiting stud is fixed to the sliding block, and the outer wall of the limiting stud is slidably connected to the sliding groove, a fixing nut is installed on the outside of the limiting stud, and the fixing nut and the limiting stud are matched through threads.

[0009] Preferably, a sensor is arranged above the assembly plate, a mounting seat is fixedly arranged at the bottom of the sensor, guide grooves are arranged inside both sides of the mounting seat, the guide grooves are open to the outside, and the guide grooves are engaged with the limiting studs.

[0010] Preferably, a plurality of arc-shaped grooves are arranged at the front and rear of the movable groove, a plurality of spring sheets are arranged at the front and rear of the assembly plate, and the spring sheets are engaged with the arc-shaped grooves.

[0011] Preferably, a clamping plate is installed on the upper end surface of the mounting frame, the four corners of the clamping plate are fixed to the mounting frame by screws, and the inner side of the clamping plate is closed above the arc groove and the spring sheet.

[0012] Preferably, fixing frames are provided on both sides of the mounting frame, a damping buffer is installed between the fixing frame and the mounting frame, and a shock-absorbing spring is installed between the fixed end and the movable end of the damping buffer.

[0013] Preferably, a mounting hole is provided on one side of the fixing frame, and the mounting hole is fixed to the assembly device by bolts.

[0014] Preferably, after the sensor is assembled, the fixing nut is located on the upper end surface of the mounting seat.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model adopts a flexible assembly structure. When facing current sensors of different specifications, the spacing between the two is expanded by pulling the limit stud, thereby providing space for the placement of the sensor mounting seat. After loosening the limit stud, the support spring will be elastically reset, and the limit studs will be driven to approach each other through the sliding block. During the approaching process, they will enter the guide groove of the mounting seat, thereby forming a close contact with the inner side of the guide groove to complete the pre-positioning of the sensor. Subsequently, the fixing nut is placed on the upper end of the limit stud and rotated using a tool, so that the lower end face of the fixing nut is closely fitted to the upper end face of the mounting seat under the cooperation of the thread, thereby fixing the sensor at this position. The assembly structure is convenient and easy to operate, and can be quickly installed according to current sensors of different specifications while ensuring assembly stability.

[0017] 2. The utility model adopts a movable connection between the assembly plate and the mounting frame. Arc grooves are provided on both sides of the movable groove inside the assembly plate, and spring sheets are correspondingly provided on both sides of the assembly plate. When the spring sheet is engaged with the arc groove, a limit is formed on the assembly plate, so that it remains stable at this position. When the spacing of the current sensor needs to be adjusted, pressure is applied to the assembly plate in the adjustment direction. Under the action of pressure, the arc groove squeezes the spring sheet, causing it to gradually shrink, so that the assembly plate can gradually move. After reaching the specified position, the spring sheet and the arc groove are engaged again so that the assembly plate can be fixed at this position to achieve spacing adjustment. The movable mounting structure further improves the flexibility, and the position of the current sensor can be quickly adjusted according to the usage during work.

[0018] 3. The utility model is provided with a shock absorbing mechanism. When vibration occurs during the operation of the assembly equipment, the vibration force will be transmitted to the shock absorbing spring and the damping buffer through the fixing frame. On the one hand, the shock absorbing spring undergoes elastic deformation, and the vibration force can be transformed during the deformation process, thereby reducing the impact on the current sensor. On the other hand, the damping buffer can make the mounting frame reset more smoothly, thereby improving the stability of the entire shock absorbing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] When facing current sensors of different specifications, the distance between the two is enlarged by pulling the limit stud 11 to provide space for the placement of the sensor 2 on the mounting base 3. After loosening the limit stud 11, the support spring 10 will be elastically reset, and the limit stud 11 will be driven to approach each other through the sliding block 9. During the approaching process, it will enter the guide groove 4 of the mounting base 3, thereby forming a close contact with the inner side of the guide groove 4 to complete the pre-positioning of the sensor 2. Subsequently, the fixing nut 12 is placed on the upper end of the limit stud 11 and rotated using a tool, so that the lower end face of the fixing nut 12 is tightly fitted with the upper end face of the mounting base 3 under the cooperation of the thread, thereby fixing the sensor 2 at this position.

[0029] See also Figure 1 , Figure 3 and Figure 4A sensor 2 is arranged above the assembly plate 6, a mounting seat 3 is fixedly arranged at the bottom of the sensor 2, guide grooves 4 are arranged inside both sides of the mounting seat 3, the guide grooves 4 are open to the outside, and the guide grooves 4 are engaged with the limiting studs 11. The assembly structure is convenient and easy to operate, and can be quickly installed according to current sensors of different specifications while ensuring assembly stability.

The four corners of the card plate 17 are fixed to the mounting frame 1 by screws, and the inner side of the card plate 17 is closed above the arc groove 18 and the spring sheet 19, forming a limit for the front and rear ends of the assembly plate 6 to improve the assembly stability.
