Description

Technical Field

[0001] The utility model relates to the technical field of current sensors, in particular to a current sensor which is convenient to install and disassemble. Background Art

[0002] A current sensor is a detection device that senses the measured current and, according to a specific pattern, converts this information into an electrical signal or other desired form of information output that meets certain standards. This output satisfies requirements for information transmission, processing, storage, display, recording, and control. Current sensors, also known as magnetic sensors, can be used in power transmission monitoring, current monitoring in distribution rooms, household appliances, smart grids, electric vehicles, wind power generation, and other fields.

[0003] Most current sensors in the existing technology are connected by bolts. When the sensor needs to be replaced or maintained, both installation and removal take a lot of time. In addition, the position of the current sensor is inconvenient to adjust, and multiple bolts need to be tightened multiple times. During the movement or maintenance process, the bolts are easily lost, affecting subsequent use. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a current sensor that is easy to install and disassemble.

[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: a current sensor that is easy to install and disassemble, including a mounting plate, a sliding seat is fixed on the upper surface of the mounting plate, the mounting plate is provided with a mounting seat, the side wall of the mounting seat is penetrated by a sliding opening that is slidably connected to the sliding seat, the upper surface of the mounting seat is fixed with a current sensor body, the side wall of the sliding seat is provided with a tooth groove, and a fixing component for fixing the fixing seat is installed on the mounting seat, the fixing component includes a connecting rod that is penetrated and slidably connected on the side wall of the sliding seat, a fixing block fixed to one end of the cross bar close to the sliding seat and engaged with the tooth groove, and a control block fixed to the end of the cross bar away from the fixed block.

[0006] By adopting the above technical solution, when the current sensor body needs to be installed, the sliding opening is aligned with the sliding seat and inserted, and the fixed block is pulled outward by the control block to move the mounting seat on the sliding seat and adjust the position of the current sensor body. The fixed block is then moved to the side close to the sliding seat by the control block so that the fixed block is pressed against the tooth groove, thereby fixing the position of the mounting seat and the current sensor body, eliminating the tedious operation of fixing with multiple bolts, and facilitating the installation and disassembly of the current sensor.

[0007] Furthermore, a mounting groove is provided on the side wall of the mounting seat, and a spring sleeved on the connecting rod is provided in the mounting groove. One end of the spring is fixed to the inner wall of the mounting groove, and the other end of the spring is fixed to the side wall of the control block.

[0008] By adopting the above technical solution, the control block keeps the fixed block in a state of being tightly pressed against the tooth groove under the elastic force of the spring, reducing the probability of the fixed block being separated from the state of being tightly pressed against the tooth groove, thereby reducing the probability of displacement of the mounting seat.

[0009] Furthermore, the cross section of the connecting rod is rectangular.

[0010] By adopting the above technical solution, the rectangular cross section prevents the connecting rod from rotating, thereby reducing the probability of the fixing block being out of the state of being pressed against the tooth groove due to rotation.

[0011] Furthermore, a limiting groove cooperating with the fixing block is formed on the inner wall of the sliding opening, and the cross-sectional area of the fixing block is larger than the cross-sectional area of the connecting rod.

[0012] By adopting the above technical solution, the tedious operation of realigning the fixing block with the tooth groove due to separation of the fixing block and the connecting rod is avoided, thereby reducing the probability of the fixing block and the connecting rod falling off.

[0013] Furthermore, a rubber pad is fixed to the side wall of the fixing block away from the connecting rod.

[0014] By adopting the above technical solution, the rubber pad is made of rubber material, and its surface has a large friction coefficient. The fixed block cooperates with the tooth groove and presses against the rubber pad, which increases the friction between the fixed block and the tooth groove and enhances the stability of the fixed assembly.

[0015] Furthermore, the cross-sections of the sliding opening and the sliding seat are both dovetail-shaped.

[0016] By adopting the above technical solution, the dovetail-shaped sliding opening and the sliding seat prevent the mounting seat from being separated from the sliding seat upward, thereby enhancing the stability of the mounting seat and the current sensor body.

[0017] Furthermore, an arc groove is opened on the upper surface of the sliding seat, a ball rollingly connected to the arc groove is embedded in the top wall of the sliding opening, and the gap distance between the top wall of the sliding opening and the upper surface of the sliding seat is 0.2-0.4mm.

[0018] By adopting the above technical solution, the ball is connected to the arc groove in a rolling manner, so that the sliding friction between the sliding opening and the sliding seat is converted into rolling friction, reducing the resistance of the mounting seat to movement on the sliding seat, making it easier for workers to adjust the position of the current sensor body.

[0019] Furthermore, the side walls on both sides of the sliding seat are provided with plugging grooves, and the plugging grooves are provided with limiting plates that are plugged into the plugging grooves. The cross-sections of the plugging grooves and the limiting plates are both dovetail-shaped.

[0020] By adopting the above technical solution, when installing the current sensor body, the staff aligns the sliding port with the sliding seat and inserts it, and then plugs the limit plate into the plug-in slot to limit the moving position of the mounting seat, thereby preventing the mounting seat from detaching from the sliding seat. The cross-section of the plug-in slot and the limit plate is dovetail-shaped, which reduces the probability of the limit plate detaching from the plug-in slot.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. In this application, when the current sensor body needs to be installed, the sliding port is aligned with the sliding seat and inserted, and the fixed block is pulled outward by the control block to move the mounting seat on the sliding seat and adjust the position of the current sensor body. Then, the fixed block is moved to the side close to the sliding seat by the control block so that the fixed block is pressed against the tooth groove, thereby fixing the position of the mounting seat and the current sensor body, eliminating the tedious operation of fixing with multiple bolts, and facilitating the installation and removal of the current sensor.

[0023] 2. In this application, the control block keeps the fixed block in a tight state against the tooth groove under the elastic force of the spring, reducing the probability of the fixed block being separated from the tight state against the tooth groove, thereby reducing the probability of displacement of the mounting seat;

[0024] 3. In the present application, the rectangular cross section prevents the connecting rod from rotating, thereby reducing the probability of the fixing block being out of the tight state with the tooth groove due to rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] like Figure 1-4 As shown, an embodiment of the present application discloses a current sensor that is easy to install and disassemble, including a mounting plate 1, a sliding seat 2, a mounting seat 3, a current sensor body 4 and a fixing assembly 5.

[0032] Mounting plate 1 is a rectangular plate-like structure used to support the device. Sliding seat 2, with a dovetail-shaped cross section, is fixed to the top surface of mounting plate 1. Sliding seat 2 has tooth grooves 21 defined in its sidewalls. Mounting seat 3 is located on the top surface of mounting plate 1. A sliding opening 31, extending through its sidewall for slidably connecting to sliding seat 2, is defined in a rectangular cross section.

[0033] The fixing assembly 5 is mounted on the mounting base 3 and is used to secure the mounting base. The fixing assembly 5 comprises a connecting rod 51, a fixing block 52, and a control block 53. The connecting rod 51 is a rod-shaped structure that extends through the side wall of the sliding base 2 and is slidably connected to the sliding base 2. The fixing block 52 is fixed to the end of the crossbar closest to the sliding base 2 and engages with the tooth groove 21. The control block 53 is a round block-shaped structure that is fixed to the end of the crossbar away from the fixing block 52.

[0034] When the current sensor body 4 needs to be installed, the sliding opening 31 is aligned with the sliding seat 2 and inserted, and the fixing block 52 is pulled outward by the control block 53 to move the mounting seat 3 on the sliding seat 2 and adjust the position of the current sensor body 4. The fixing block 52 is then moved to the side close to the sliding seat 2 by the control block 53, so that the fixing block 52 is pressed against the tooth groove 21, thereby fixing the position of the mounting seat 3 and the current sensor body 4, eliminating the tedious operation of fixing with multiple bolts, facilitating the installation and disassembly of the current sensor, and the dovetail-shaped sliding opening 31 and the sliding seat 2 prevent the mounting seat 3 from detaching upward from the sliding seat 2, thereby enhancing the stability of the mounting seat 3 and the current sensor body 4.

[0035] In order to reduce the probability of displacement of the mounting seat 3, a mounting groove 32 is opened on the side wall of the mounting seat 3, and a spring 6 is provided in the mounting groove 32 and is sleeved on the connecting rod 51. One end of the spring 6 is fixed to the inner wall of the mounting groove 32, and the other end of the spring 6 is fixed to the side wall of the control block 53. Under the elastic force of the spring 6, the control block 53 keeps the fixing block 52 in a state of being tightly pressed against the tooth groove 21, thereby reducing the probability of the fixing block 52 being separated from the state of being tightly pressed against the tooth groove 21, thereby reducing the probability of displacement of the mounting seat 3.

[0036] In order to reduce the probability of the fixing block 52 being out of the tight state with the tooth groove 21 due to rotation, the cross-section of the connecting rod 51 is rectangular. The rectangular cross-section avoids the rotation of the connecting rod 51, thereby reducing the probability of the fixing block 52 being out of the tight state with the tooth groove 21 due to rotation.

[0037] In order to reduce the probability of the fixing block 52 and the connecting rod 51 falling off, a limiting groove 33 cooperating with the fixing block 52 is opened on the inner wall of the sliding opening 31. The cross-sectional area of the fixing block 52 is larger than the cross-sectional area of the connecting rod 51, eliminating the tedious operation of the staff to re-align the fixing block 52 with the tooth groove 21 due to the separation of the fixing block 52 and the connecting rod 51, thereby reducing the probability of the fixing block 52 and the connecting rod 51 falling off.

[0038] In order to enhance the stability of the fixing assembly 5, a rubber pad 7 is fixed to the side wall of the fixing block 52 away from the connecting rod 51. The rubber pad 7 is made of rubber material and its surface has a large friction coefficient. The fixing block 52 cooperates with the tooth groove 21 and presses against the rubber pad 7, thereby increasing the friction between the fixing block 52 and the tooth groove 21, thereby enhancing the stability of the fixing assembly 5.

[0039] In order to make it easier for the staff to adjust the position of the current sensor body 4, an arc-shaped groove 22 is opened on the upper surface of the sliding seat 2, and a ball 8 is embedded in the top wall of the sliding opening 31 and is rollingly connected to the arc-shaped groove 22. The gap distance between the top wall of the sliding opening 31 and the upper surface of the sliding seat 2 is 0.2-0.4mm. The ball 8 is rollingly connected to the arc-shaped groove 22, so that the sliding friction between the sliding opening 31 and the sliding seat 2 is converted into rolling friction, reducing the resistance of the mounting seat 3 to the movement of the sliding seat 2, thereby making it easier for the staff to adjust the position of the current sensor body 4.

[0040] In order to limit the moving position of the mounting seat 3, the side walls on both sides of the sliding seat 2 are provided with plug-in grooves 23, and the plug-in grooves 23 are provided with limit plates 9 that are plugged into the plug-in grooves 23. The cross-sections of the plug-in grooves 23 and the limit plates 9 are both dovetail-shaped. When installing the current sensor body 4, the staff aligns the sliding opening 31 with the sliding seat 2 and inserts it, and then plugs the limit plates 9 into the plug-in grooves 23, which limits the moving position of the mounting seat 3 and avoids the mounting seat 3 from detaching from the sliding seat 2. The cross-sections of the plug-in grooves 23 and the limit plates 9 are dovetail-shaped, which reduces the probability of the limit plates 9 detaching from the plug-in grooves 23.

[0041] The operating principle of a current sensor that is easy to install and disassemble in this embodiment is as follows: when the current sensor body 4 needs to be installed, the sliding opening 31 is aligned with the sliding seat 2 and inserted, and the fixing block 52 is pulled outward by the control block 53 to move the mounting seat 3 on the sliding seat 2 and adjust the position of the current sensor body 4, and then the fixing block 52 is moved to the side close to the sliding seat 2 by the control block 53, so that the fixing block 52 is pressed against the tooth groove 21, thereby fixing the position of the mounting seat 3 and the current sensor body 4, eliminating the tedious operation of fixing with multiple bolts, and facilitating the installation and disassembly of the current sensor. The dovetail-shaped sliding opening 31 and the sliding seat 2 prevent the mounting seat 3 from detaching upward from the sliding seat 2, thereby enhancing the stability of the mounting seat 3 and the current sensor body 4.

[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
