Description

Technical Field

[0001] This utility model relates to the field of current sensors, specifically a vibration-resistant and high-temperature resistant current sensor base. Background Technology

[0002] A current sensor is a detection device that can sense the information of the measured current and transform the sensed information into an electrical signal or other required form of information output that meets certain standards, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] When installing a current sensor, it needs to be installed with a base. However, existing current sensor bases require pressing two limiting blocks against the outside of the sensor, which can easily cause the sensor to tilt during installation. Therefore, those skilled in the art have provided a vibration-proof and high-temperature resistant current sensor base to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a vibration-resistant and high-temperature resistant current sensor base, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-resistant and high-temperature-resistant current sensor base, comprising a base body and two pressure plates symmetrically mounted on the top of the base body, further comprising: a heat dissipation frame disposed inside the base body for dissipating heat from the current sensor; a sliding plate fixedly connected to the bottom of each pressure plate; a groove provided on the surface of the base body for limiting the sliding of the sliding plate; a sleeve frame fixedly connected between the two sliding plates for facilitating synchronous pressing of the two pressure plates; the sleeve frame movably fitting onto the outside of the base body; a clamping mechanism for fixing and pressing the pressure plates, the clamping mechanism being installed inside the base body; and a loosening mechanism for opening and disassembling the pressure plates, the loosening mechanism being installed inside the base body.

[0006] Preferably, the snap-fit ​​mechanism includes two symmetrically installed locking blocks within the grooves of the base body. The top of each locking block has a sloping structure, facilitating the movement of the pressing slide along the sloping surface of the locking block. Multiple equally spaced slots are provided on the outer side of the slide for the locking blocks to be inserted and positioned. A slide bar is fixedly connected to the end of each locking block away from the slide. A sliding groove is provided inside the base body for the slide bar to be slidably positioned. A spring is fixedly connected between the inner wall of the groove and the slide bar. The elasticity of the spring facilitates the insertion of the locking block into the slot. Simultaneously, pressing the two pressure plates causes the slots on the slide to move along the sloping surface of the locking block, inserting the slide bar into the groove and compressing the spring. This causes the pressure plates to contact the top of the current sensor for installation. The rebound force of the spring then inserts the locking block into the corresponding slot. The sleeve ensures that the two pressure plates move downwards smoothly, preventing the current sensor from tilting and achieving a rapid installation effect.

[0007] Preferably, the slide release mechanism includes a pressure strip installed on the outside of the slide plate. The pressure strip contacts the outside of the slide plate, providing a limit for the outside of the slide plate and improving the stability of the slide plate movement. Both ends of the pressure strip are fixedly connected to insert blocks that slide into the inside of the base body. A positioning plate is fixedly connected to the bottom of the insert block. The inside of the base body has a cavity for the positioning plate to slide and limit. The bottom of the positioning plate is fixedly connected to the slide strip. The surface of the slide strip has a through hole for the insert strip to be inserted. A stop block is fixedly connected to the inside of the through hole. The insert strip contacts the stop block. The contact surfaces of the stop block and the insert strip are both inclined structures, which facilitates the slide strip to be retracted into the groove of the base body. Pressing the pressure strip can move the insert strip along the inclined surface of the stop block and retract the locking block on the slide strip into the groove of the base body, making it easy to pull the pressure plate upwards and disassemble the current sensor, thus achieving the effect of easy disassembly.

[0008] Preferably, three equidistant positioning rods are fixedly connected to the bottom of the groove of the base body, and the positioning rods slide into the interior of the slide plate to improve the stability of the slide plate movement.

[0009] Preferably, a limiting plate is fixedly connected between the three positioning rods, and a cavity is provided inside the sliding plate for the limiting plate to slide in a limited manner, so as to prevent the sliding plate from falling off the base body.

[0010] Preferably, the top of the pressure plate is provided with a pressing groove to facilitate pressing operation.

[0011] Preferably, two rubber pads are fixedly connected to the bottom of the pressure plate to improve the stability of the pressure plate for installing the current sensor.

[0012] Preferably, a heat insulation pad is fixedly connected to the bottom inner wall of the base body to improve the high temperature resistance of the base body.

[0013] Preferably, four equidistant springs are fixedly connected between the top of the heat insulation pad and the heat dissipation frame to provide vibration damping for the current transformer.

[0014] Preferably, the bottom of both the heat insulation pad and the base body is provided with a plurality of equidistant vent holes, and the bottom of the base body is provided with a vent groove for venting the air through the vent holes. The vent groove extends to the outside of the base body to facilitate heat dissipation.

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

[0016] 1. This utility model uses a snap-fit ​​mechanism to simultaneously press two pressure plates, causing the slots on the slide plate to move along the inclined surface of the card block. This allows the pressure plates to contact the top of the current sensor for installation. The spring force of spring one is used to insert the card block into the corresponding slot. The sleeve frame ensures that the two pressure plates move downwards smoothly, preventing the current sensor from tilting, thus achieving a quick installation effect.

[0017] 2. This utility model uses a loosening plate mechanism. Pressing the pressure bar moves the insertion bar on the insertion block along the inclined surface of the abutment block, and puts the locking block on the slide bar into the slide groove of the base body, making it easy to pull the pressure plate upward and disassemble the current sensor, thus achieving the effect of easy disassembly.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1 and Figure 2 The diagram shows a vibration-resistant and high-temperature resistant current sensor base, comprising a base body 1 and two pressure plates 2 symmetrically mounted on the top of the base body 1. It also includes: a heat dissipation bracket 5 located inside the base body 1 for cooling the current sensor; a sliding plate 6 fixedly connected to the bottom of the pressure plates 2; grooves on the surface of the base body 1 for limiting the sliding of the sliding plate 6; a frame 7 fixedly connected between the two sliding plates 6 for synchronous pressing of the two pressure plates 2; the frame 7 movably fitting onto the outside of the base body 1; a clamping mechanism 3 for fixing and pressing the pressure plates 2; and a loosening mechanism 4 for opening and disassembling the pressure plates 2; the loosening mechanism 4 is also installed inside the base body 1.

[0028] Please see Figure 2 and Figure 3 The buckle mechanism 3 shown in the figure includes two symmetrically installed locking blocks 301 in the groove of the base body 1. The top of the locking block 301 is a sloping structure, which makes it easy to press the slide plate 6 to move along the sloping surface of the locking block 301. Multiple slots are provided on the outer side of the slide plate 6 for the locking blocks 301 to be inserted and positioned. A slide bar 302 is fixedly connected to the end of the locking block 301 away from the slide plate 6. A slide groove is provided inside the base body 1 for the slide bar 302 to be slid and limited. A spring 303 is fixedly connected between the inner wall of the slide groove and the slide bar 302. The elasticity of the spring 303 makes it easy for the locking block 301 to be inserted into the slot.

[0029] The user places the current sensor onto the heat sink 5 of the base body 1, and then simultaneously presses down on the two pressure plates 2, causing the slots on the slide plate 6 to move along the inclined surface of the block 301. The slide bar 302 is inserted into the slide groove, and the spring 303 is compressed, so that the pressure plate 2 contacts the top of the current sensor for installation. The spring 303's rebound force pushes the block 301 on the slide bar 302 into the corresponding slot. The sleeve 7 ensures that the two pressure plates 2 move downward smoothly, preventing the current sensor from tilting inside the base body 1, thus achieving a quick and stable installation.

[0030] Please see Figure 2 and Figure 3 The slide release mechanism 4 shown in the figure includes a pressure strip 401 installed on the outside of the slide plate 6. The pressure strip 401 contacts the outside of the slide plate 6 and provides a limit for the outside of the slide plate 6, improving the stability of the slide plate 6 movement. Both ends of the pressure strip 401 are fixedly connected to the insert block 402 that slides into the inside of the base body 1. The bottom of the insert block 402 is fixedly connected to the positioning plate 403. The inside of the base body 1 is provided with a cavity for the positioning plate 403 to slide in a limited manner. The bottom of the positioning plate 403 is fixedly connected to the insert strip 404. The surface of the slide strip 302 is provided with a through hole for the insert strip 404 to be inserted. The inside of the through hole is fixedly connected to the abutment block 405. The insert strip 404 contacts the abutment block 405. The contact surfaces of the abutment block 405 and the insert strip 404 are both inclined structures, which facilitates the slide strip 302 to be put into the groove of the base body 1.

[0031] When the current sensor needs to be disassembled, the user presses the two pressure strips 401 downwards, and the positioning plate 403 on the insertion block 402 drives the insertion strip 404 to move along the inclined surface of the abutment block 405, so that the locking block 301 on the slide strip 302 is put into the slide groove of the base body 1, making it easy to pull the pressure plate 2 upwards, and thus disassemble the current sensor, achieving the effect of quick disassembly.

[0032] The working principle for facilitating the smooth installation and removal of the current sensor is as follows: First, the user places the current sensor on the heat sink 5 of the base body 1. Then, the user presses down on the two pressure plates 2 simultaneously, causing the slide plate 6 to move along the outside of the pressure strip 401. The slot on the slide plate 6 moves along the inclined surface of the locking block 301, pushing the locking block 301 to move. The slide strip 302 is inserted into the slide groove, and the spring 303 is compressed, so that the pressure plate 2 contacts the top of the current sensor for installation. The spring 303 pushes the locking block 301 on the slide strip 302 into the corresponding slot. The sleeve 7 ensures that the two pressure plates 2 move downward smoothly, preventing the current sensor from tilting inside the base body 1, thus achieving a fast and smooth installation.

[0033] When the current sensor needs to be disassembled, the user presses the two pressure strips 401 downwards, and the positioning plate 403 on the insertion block 402 drives the insertion strip 404 to move along the inclined surface of the abutment block 405, so that the locking block 301 on the slide strip 302 is put into the slide groove of the base body 1, making it easy to pull the pressure plate 2 upwards, so that the current sensor can be disassembled, thus achieving the effect of quick disassembly.

[0034] Example 2

[0035] Please see Figures 2-4 This embodiment further illustrates Example 1. In the figure, three equidistant positioning rods 8 are fixedly connected to the bottom of the groove of the base body 1. The positioning rods 8 slide into the interior of the slide plate 6 to improve the stability of the slide plate 6. A limiting plate 9 is fixedly connected between the three positioning rods 8. A cavity is provided inside the slide plate 6 for the limiting plate 9 to limit the sliding, preventing the slide plate 6 from falling off the base body 1. A pressing groove is provided on the top of the pressure plate 2 to facilitate pressing operation. Two rubber pads 10 are fixedly connected to the bottom of the pressure plate 2 to improve the firmness of the pressure plate 2 for the installation of the current sensor.

[0036] In this embodiment, the user can contact the pressing groove with their finger and push the slide plate 6 on the pressure plate 2 to move along the outside of the limiting plate 9 and the positioning rod 8, which improves the stability of the movement of the slide plate 6 and prevents the slide plate 6 from falling off the base body 1, making it easy to store. When the locking block 301 is aligned with the slot, the elasticity of the rubber pad 10 makes it easy for the locking block 301 to be inserted into the slot, and improves the firmness of the pressure plate 2 in fixing the current sensor.

[0037] Example 3

[0038] Please see Figure 4 and Figure 5 This embodiment further illustrates other embodiments. In the figure, a heat insulation pad 11 is fixedly connected to the bottom inner wall of the base body 1 to improve the high temperature resistance of the base body 1. Four springs 12 are fixedly connected between the top of the heat insulation pad 11 and the heat sink 5 to provide vibration reduction for the current transformer. Multiple vent holes are provided at equal intervals on the bottom of both the heat insulation pad 11 and the base body 1. A vent groove is provided on the bottom of the base body 1 to allow the vent holes to vent. The vent groove extends to the outside of the base body 1 to facilitate heat dissipation.

[0039] In this embodiment: when the current sensor is installed, the vibration reduction effect of the current sensor is improved by the second spring 12, and the temperature generated by the current sensor can be discharged through the heat sink 5 and the vent holes and vent grooves of the base body 1, thereby improving the heat dissipation effect of the current sensor.
