Description

Technical Field

[0001] This invention relates to the field of voltage sensors, specifically a voltage sensor for electromechanical monitoring. Background Technology

[0002] A voltage sensor is a sensor that can sense the voltage being measured and convert it into a usable output signal. In various automatic detection and control systems, it is often necessary to track and acquire rapidly changing AC and DC voltage signals and perform spectrum analysis on complex voltage waveforms.

[0003] Voltage sensors are often used to detect voltage fluctuations in computer rooms or between residential floors. However, dust tends to accumulate in computer rooms, making it difficult to observe the data when dust accumulates on the surface of the voltage sensor. Furthermore, the wires connected to the voltage sensor are fixed to the surface of the voltage sensor by fixing components, and when the wires are pulled, they are easily damaged, leading to poor contact. Summary of the Invention

[0004] The purpose of this invention is to provide a voltage sensor for electromechanical monitoring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a voltage sensor for electromechanical monitoring, comprising:

[0006] The outer casing has a first extension block and a second extension block fixed to its surface.

[0007] The protective plate has an L-shaped plate at one end, an arc-shaped plate at the other end, a groove on the surface of the arc-shaped plate, a crossbar inside the groove, a movable plate on the surface of the crossbar, and a slot on the surface of the movable plate.

[0008] The conductor has a retaining ring on its surface, and the retaining ring has an extension ring on its surface.

[0009] Preferably, L-shaped plates are fixed on both sides of the protective plate. The surface of the L-shaped plates is provided with through grooves, and multiple sets of through grooves are provided. A plug plate is inserted into the surface of the first extension block. The plug plate can move inside the first extension block. A pivot is provided at the end of the plug plate. A protective plate is provided on the surface of the pivot. The protective plate is hinged to the end of the plug plate through the pivot. The protective plate can swing along the pivot.

[0010] Preferably, the surface of the second extension block is provided with an insertion groove, and the end of the protective plate can be inserted into the interior of the insertion groove. Both sides of the protective plate are provided with rubber strips. When the protective plate is inserted into the interior of the first extension block and the insertion groove, the rubber strips on the surface of the protective plate abut against the interior of the first extension block and the inner wall of the insertion groove.

[0011] Preferably, the arc-shaped plate is fixed on the surface of the L-shaped plate, and two sets of limiting sleeves are provided inside the arc-shaped plate. The limiting sleeves are located at both ends of the arc-shaped plate, and when the arc-shaped plate descends with the protective plate, the arc-shaped plate is stuck outside the wire, and the limiting sleeves are stuck on both sides of the wire, so that the wire is stuck inside the arc-shaped plate.

[0012] Preferably, the surface of the arc-shaped plate has two sets of slots, the crossbar is fixed inside the slots, the movable plate can move laterally on the surface of the crossbar, the surface of the crossbar is provided with a spring, one end of the spring is connected to the surface of the movable plate, the other end of the spring is connected to the inside of the slot, the spring has a pushing force on the movable plate, so that the movable plate is located on one side of the slot.

[0013] Preferably, when the arc-shaped plate is located on the surface of the conductor, the extension ring is located in the slot on the surface of the moving plate. The conductor is fixed to the surface of the housing by a fixing component, and an arc-shaped rod is fixed on the surface of the housing. A rubber ball is provided on the surface of the arc-shaped rod, and two sets of through holes are opened on the surface of the extension ring. The position of the arc-shaped rod corresponds to the position of the through holes, and the rubber ball can be stuck in the through holes.

[0014] Preferably, when the rubber ball is inserted into the through hole, the end of the wire near the outer shell is bent, the fixing ring is fixed to the surface of the wire, and the extension ring moves with the moving plate. When the moving plate moves, the extension ring drives the fixing ring to move, and the bent end of the wire straightens.

[0015] Preferably, the arc-shaped rod is elastic, and when the arc-shaped rod moves with the conductor, the arc-shaped rod is straightened, and the distance between the outer shell and the rubber ball is less than the distance between the extension ring and the outer shell.

[0016] Preferably, the surface of the outer casing has multiple sets of fixing holes, the end of the wire is inserted into the fixing hole, and the wire is fixed inside the fixing hole by a screw.

[0017] Preferably, a threaded hole is provided on one side of the fixing hole, and the position of the threaded hole on one side of the fixing hole corresponds to the position of the through groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] In actual use, the plug-in plate is pulled out of the first extension block, and the end of the protective plate away from the plug-in plate is pulled out from the plug-in groove on the surface of the second extension block. The protective plate can swing along the pivot, exposing the screen and buttons on the surface of the outer casing. When both ends of the protective plate are inserted into the plug-in groove and the interior of the first extension block, the L-shaped plate descends with the protective plate. The through groove will not obstruct the assembly for fixing the wire. The end of the wire is fixed to the surface of the outer casing. The end of the wire closest to the outer casing is bent, and the rubber ball at the end of the arc-shaped rod is inserted into the through hole on the surface of the fixing ring. The wire is stabilized in a bent state. After the arc plate rises and falls with the L-shaped plate, the wire is locked inside the arc plate, and the limiting sleeve inside the arc plate acts to hold the wire in place. The fixing ring is inserted into the slot on the surface of the moving plate. A crossbar is inserted inside the moving plate, and a spring is installed on the surface of the crossbar. When the wire is pulled, the moving plate moves on the surface of the crossbar, and the spring is compressed. Since the wire is bent at the end near the outer shell, the wire can move with the moving plate, which plays a buffering role and reduces the degree of damage when the wire is pulled.

[0029] Example 1

[0030] Please see Figures 1-7 The present invention provides a technical solution: a voltage sensor for electromechanical monitoring, comprising: a housing 1, on the surface of the housing 1, a first extension block 2 and a second extension block 6 fixed thereon; a protective plate 3, an L-shaped plate 5 at one end of the protective plate 3, an arc-shaped plate 8 at one end of the L-shaped plate 5, a slot 10 on the surface of the arc-shaped plate 8, a crossbar 9 inside the slot 10, a movable plate 12 on the surface of the crossbar 9, and a slot 13 on the surface of the movable plate 12; a wire 15, a fixing ring 16 on the surface of the wire 15, an extension ring 17 on the surface of the fixing ring 16, a limiting sleeve 14 inside the arc-shaped plate 8 for securing the wire 15, the fixing ring 16 being inserted into the slot 13 on the surface of the movable plate 12, a crossbar 9 being inserted inside the movable plate 12, and a spring 11 on the surface of the crossbar 9, wherein when the wire 15 is pulled, the movable plate 12 moves on the surface of the crossbar 9, and the spring 11 is compressed.

[0031] Example 2

[0032] Based on Embodiment 1, L-shaped plates 5 are fixed on both sides of the protective plate 3. The surface of the L-shaped plate 5 is provided with through grooves 4, and multiple sets of through grooves 4 are provided. A plug-in plate 19 is inserted into the surface of the first extension block 2. The plug-in plate 19 can move inside the first extension block 2. A pivot 21 is provided at the end of the plug-in plate 19. The surface of the pivot 21 is provided with the protective plate 3. The protective plate 3 is hinged to the end of the plug-in plate 19 through the pivot 21. The protective plate 3 can swing along the pivot 21. The screen and buttons on the surface of the outer shell 1 are exposed. When the two ends of the protective plate 3 are inserted into the plug-in grooves 7 and the interior of the first extension block 2, the L-shaped plate 5 descends with the protective plate 3, and the through grooves 4 will not block the components that fix the wire 15.

[0033] The surface of the second extension block 6 is provided with an insertion groove 7, and the end of the protective plate 3 can be inserted into the interior of the insertion groove 7. Rubber strips 20 are provided on both sides of the protective plate 3. When the protective plate 3 is inserted into the interior of the first extension block 2 and the insertion groove 7, the rubber strips 20 on the surface of the protective plate 3 abut against the interior of the first extension block 2 and the inner wall of the insertion groove 7.

[0034] The arc-shaped plate 8 is fixed to the surface of the L-shaped plate 5. Two sets of limiting sleeves 14 are installed inside the arc-shaped plate 8, located at both ends. When the arc-shaped plate 8 descends with the protective plate 3, it is locked onto the outside of the wire 15, while the limiting sleeves 14 are locked onto both sides of the wire 15, thus securing the wire 15 inside the arc-shaped plate 8. Two sets of slots 10 are formed on the surface of the arc-shaped plate 8, and the crossbar 9 is fixed inside the slots 10. The moving plate 12 can move laterally across the surface of the crossbar 9. A spring 11 is installed on the surface of the crossbar 9, with one end of the spring 11 connected to… Next, on the surface of the movable plate 12, the other end of the spring 11 is connected to the inside of the slot 10. The spring 11 exerts a pushing force on the movable plate 12, causing the movable plate 12 to be located on one side of the slot 10. When the arc plate 8 is located on the surface of the wire 15, the extension ring 17 is located in the slot 13 on the surface of the movable plate 12. The wire 15 is fixed to the surface of the housing 1 by a fixing assembly, and an arc rod 22 is fixed on the surface of the housing 1. A rubber ball 23 is provided on the surface of the arc rod 22. Two sets of through holes 18 are opened on the surface of the extension ring 17. The position of the arc rod 22 is related to the through holes 18. The position of the hole 18 corresponds to the position of the rubber ball 23, which can be stuck in the through hole 18. When the rubber ball 23 is stuck in the through hole 18, the end of the wire 15 near the outer shell 1 is bent, the fixing ring 16 is fixed to the surface of the wire 15, and the extension ring 17 moves with the moving plate 12. When the moving plate 12 moves, the extension ring 17 drives the fixing ring 16 to move, the bent end of the wire 15 straightens, and the arc rod 22 is elastic. When the arc rod 22 moves with the wire 15, the arc rod 22 is straightened, and the distance between the outer shell 1 and the rubber ball 23 is less than that of the extension ring 17. The distance from the outer casing 1 is such that multiple sets of fixing holes 24 are opened on the surface of the outer casing 1. The end of the wire 15 is inserted into the fixing hole 24 and the wire 15 is fixed inside the fixing hole 24 by a screw. A threaded hole is opened on one side of the fixing hole 24, and the position of the threaded hole on one side of the fixing hole 24 corresponds to the position of the through groove 4. The end of the wire 15 is fixed to the surface of the outer casing 1. The end of the wire 15 near the outer casing 1 is bent, and the rubber ball 23 at the end of the arc rod 22 is inserted into the through hole 18 on the surface of the fixing ring 16 to stabilize the wire 15 in the bent state.

[0035] In actual use, the plug plate 19 is pulled out from the first extension block 2, and the end of the protective plate 3 away from the plug plate 19 is pulled out from the plug groove 7 on the surface of the second extension block 6. The protective plate 3 can swing along the pivot 21, exposing the screen and buttons on the surface of the outer casing 1. When both ends of the protective plate 3 are inserted into the plug groove 7 and the interior of the first extension block 2, the L-shaped plate 5 descends with the protective plate 3, and the through groove 4 does not obstruct the assembly for fixing the wire 15. The end of the wire 15 is fixed to the surface of the outer casing 1. The end of the wire 15 near the outer casing 1 is bent, and the rubber ball 23 at the end of the arc rod 22 is inserted into the through hole 18 on the surface of the fixing ring 16, thus securing the wire 15. 5. When the L-shaped plate 5 rises and falls, the arc plate 8 is stabilized in the bent state. The wire 15 is stuck inside the arc plate 8, and the limiting sleeve 14 inside the arc plate 8 plays the role of locking the wire 15. The fixing ring 16 is inserted into the slot 13 on the surface of the moving plate 12. A crossbar 9 is inserted inside the moving plate 12. A spring 11 is provided on the surface of the crossbar 9. When the wire 15 is pulled, the moving plate 12 moves on the surface of the crossbar 9, and the spring 11 is compressed. Since the wire 15 is bent at one end near the outer shell 1, the wire 15 can move with the moving plate 12, which plays a buffering role and reduces the degree of damage when the wire 15 is pulled.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
