For example, current sensors can be used to monitor the current of equipment such as motors and generators to determine the operating status and fault conditions of the equipment; in power systems, current sensors can be used to measure and protect circuits to ensure the safe and stable operation of power systems.

[0003] When installing, the current sensor is generally fixed by bolts or clamped, or the two fixing methods coexist on the base of the current sensor. The existing arrangement method is generally to arrange the bolts on both sides and arrange the clamping structure at the bottom of the base. However, in actual use, for the clamping installation method, in order to ensure the installation effect, the existing technology generally adopts dovetail groove installation. This installation structure can realize structural assembly and has a limit in one direction, but this structure can only slide inward from one side of the slide rail, which is inconvenient to install and has certain requirements for the layout site. At the same time, the structure cannot be locked, or the clamping fixation is realized by interference fit, which is more difficult to dismantle for the second time, and the assembly structure has defects. Based on this, it is necessary to study an adjustable assembly structure of the current sensor. Utility Model Content

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0023] Embodiment 1, this embodiment aims to provide a current sensor adjustable assembly structure, which is mainly used for the assembly structure of the current sensor. The existing current sensor assembly generally adopts a combination of bolt fixing and clamping fixing, but the clamping structure cannot adapt to the width of the rail during installation, and can only be installed from one direction, which is troublesome to assemble, difficult to lock and fix, and difficult to remove for the second time. Based on this, this embodiment provides a current sensor adjustable assembly structure.

[0024] like Figure 1-6 In the figure, a current sensor adjustable assembly structure is shown, including a current sensor body 1, a base 2, a fixed assembly structure and a clamping assembly structure. The lower part of the current sensor body is provided with an assembly base 2, the outer side of the assembly base 2 is provided with a fixed assembly structure, and the lower center thereof is provided with a clamping assembly structure. The fixed assembly structure is a fixing hole 3 opened on the base 2. The fixing hole 3 is an open structure and is distributed on both sides of the base 2. In actual use, one or both of the two fixing methods can be selected.

[0025] In this embodiment, the card-mounted assembly structure adopts a dovetail slot card-mounted structure, which includes a reverse-threaded screw 6, a slider 8 and a card seat; the base 2 is provided with an assembly hole 4 in the transverse direction, and the assembly hole 4 is a circular hole structure. In specific implementation, the assembly hole 4 passes through the fixing hole 3, and a square slide groove 5 is provided in the middle of the base 2. The assembly hole 4 is connected to the slide groove 5, and a driving screw hole adapted to the thread direction of the reverse-threaded screw 6 is provided in the slider 8. The slider 8 is adapted to be slidably sleeved in the slide groove 5 and is located on both sides of the slide groove 5. In the assembled state, the assembly hole 4 corresponds to the driving screw hole, and the reverse-threaded screw 6 is adapted to be connected in the assembly hole 4 and the driving screw hole, and a driving end head 12 is provided at the end of the reverse-threaded screw 6. By rotating the driving end head 12, the reverse thread can be rotated, and the slider 8 is translated under the limit of the slide groove 5, thereby changing the spacing between the two card seats.

[0026] A clamping seat 10 is arranged at the bottom of the slider 8, and there is a clamping area between the clamping seats 10 on both sides; the clamping seat 10 has an inward limiting groove, and the limiting grooves on both sides relatively form a dovetail-shaped clamping area.

[0027] When in use, this embodiment can adjust the spacing between the holders by rotating the reverse threaded screw 6. First, adjust the larger spacing and sit on both sides of the rail from any point, then rotate in the opposite direction to reduce the spacing between the holders, and then adapt the clamping rail to achieve structural fixation, which can adjust the assembly spacing of the current sensor body in the width direction. This design enables the sensor to adapt to the installation requirements of different assembly widths, improves the flexibility and adaptability of assembly, and the clamping can be installed at any point, and can be locked and fixed after adjustment, which is convenient for assembly and locking; it improves the scope of application and utilization of the assembly structure, is easy to fix and assemble, and has good fixation firmness, which provides great convenience and guarantee for the installation and use of the current sensor.

[0028] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the difference lies in the specific assembly implementation structure of the reverse threaded screw 6. This embodiment further illustrates the structure of the reverse threaded screw 6.

[0029] In this embodiment, Figure 5 As shown in the figure, both ends of the reverse-threaded screw 6 are fixed with assembly rods 7 that are thicker than the screw, and the assembly rods 7 are adapted to be mounted in the assembly hole 4. The specific fixing relationship can be a fixed set or a welding fixation. By arranging a structure with a thin middle part and thick ends, it is convenient to clamp and install from one side, thereby reducing the complexity of assembly.

[0030] In a specific implementation, mounting grooves 13 are provided on both sides of the slide groove 5 , bearings 11 are fixedly installed in the mounting grooves 13 , and the assembly rods 7 are adaptively mounted in the bearings 11 .

[0031] A mounting hole is provided in the slider 8, and a driving screw sleeve 9 is fixedly mounted in the mounting hole. The driving screw sleeve 9 is threadedly connected to the reverse-threaded screw 6 and is combined and fixed at the bottom of the slider 8 by a side thread passing through. The mounting hole is a spline hole with alternating protrusions and depressions, and a spline matching the driving screw sleeve is provided on the outer side.

[0032] This embodiment provides a basis for arranging the drive screw sleeve by setting a thinner reverse thread structure in the middle, that is, the drive screw sleeve is first assembled on the reverse thread screw rod 6. After the assembly is completed, its overall outer diameter is adapted to the outer diameter of the assembly rod, so that the structure can be assembled from one side of the assembly hole 4.

[0033] The above-mentioned implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. The basic concept of the utility model is to configure an adjustable rail structure at the bottom of the current sensor. The assembly structure can adjust the assembly spacing of the current sensor body in the width direction by clamping the reverse threaded screw, slider and seat in the assembly structure. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
