Description

Technical Field

In the detection of some thinner wires, it was found that the upper and lower through grooves cannot provide positioning for thin wires, resulting in the wires easily moving sideways and upwards and deviating from their positions during the needle piercing the wires, thereby interfering with the precise piercing of the needle, resulting in the actual voltage measurement being not accurate enough.

[0037] It also includes an upper shell 201, which is used to cover the top of the guide, and a buckle groove 202 is opened at the bottom of the upper shell 201, and the buckle groove 202 is used to cover the top of the buried groove 102, and a groove 2001 is opened at the bottom of the upper shell 201;

[0038] Two parallel lower semicircular magnetic cores 600 are fixedly installed on the top inner side surface of the lower shell 101, and the two lower semicircular magnetic cores 600 are located on the periphery of the two path grooves 103. The periphery of the lower semicircular magnetic cores 600 is wound with winding coils of the same specifications, and the center of the lower semicircular magnetic core 600 is concentric with the center of the buried groove 102. Two upper semicircular magnetic cores 700 of the same specifications as the lower semicircular magnetic core 600 are fixedly installed on the bottom inner side surface of the upper shell 201, and the center of the upper semicircular magnetic core 700 is concentric with the center of the buckling groove 202, and the positions of the two upper semicircular magnetic cores 700 correspond one by one to the positions of the two lower semicircular magnetic cores 600, and the outer periphery of the upper semicircular magnetic core 700 is wound with a winding of the same specifications as the lower semicircular magnetic core 600. Coil, the upper semicircular magnetic core 700 and the lower semicircular magnetic core 600 are combined to form a circular structure, the lower semicircular magnetic core 600 and the upper semicircular magnetic core 700 are used for wire current detection, the top of the lower shell 101 is fixedly installed with two left and right lower contact poles 900, and the bottom of the upper shell 201 is fixedly installed with two left and right upper contact poles 800, the upper contact poles 800 correspond to the lower contact poles 900 in position, the lower contact pole 900 terminal is electrically connected to the winding coil wire end wound around the outer periphery of the lower semicircular magnetic core 600, the upper contact pole 800 terminal is electrically connected to the winding coil wire end wound around the outer periphery of the upper semicircular magnetic core 700, and the wire end of the winding coil wound around the outer periphery of the lower semicircular magnetic core 600 is also connected to the power terminal of the device;

[0039] It also includes a positioning component 300, which is used for positioning the wire.

[0040] Specifically, the wire is passed through the inside of the embedded groove 102, and then the upper shell 201 is buckled on the top of the lower shell 101. At this time, the wire is located inside the "circular cavity" formed by the embedded groove 102 and the buckling groove 202. Due to the buckling between the upper shell 201 and the lower shell 101, the upper contact pole 800 and the lower contact pole 900 are in contact to generate a conductive effect, and the current wound on the outer winding coil of the lower semicircular magnetic core 600 is transmitted to the outer winding coil of the upper semicircular magnetic core 700, so that the lower semicircular magnetic core 600 and the upper semicircular magnetic core 700 are connected. The magnetic core 700 is combined into a circular detection structure to detect the wire located between the embedding groove 102 and the buckling groove 202. The puncture needle 500 is lifted upward by the output rod of the electric push rod 400, so that the tip of the puncture needle 500 extends upward from the inside of the puncture hole 1001 and penetrates into the inside of the wire to perform voltage detection. The wire is positioned by the positioning component 300 to ensure that the wire will not move during the puncture of the wire by the puncture needle 500, thereby ensuring that the puncture needle 500 can accurately penetrate into the inside of the wire.

[0041] Reference Figure 5 to Figure 12As shown, the positioning assembly 300 includes an active positioning clamp 301 that is slidably located inside the path groove 103, and two active positioning clamps 301 are slidably arranged inside each path groove 103, and the two active positioning clamps 301 are distributed on both sides of the embedded groove 102, and the opposite surfaces of the two active positioning clamps 301 are provided with a plurality of upper and lower slide grooves 302, and positioning clamp columns 303 are slidably installed inside the slide grooves 302, and a top spring 304 is fixedly installed between the end of the positioning clamp column 303 and the inner end of the slide groove 302, and the top spring 304 is used for left and right and top positioning of the wire, and the bottom distance between the upper and lower top springs 304 is one unit value of the national standard wire, and a lap block 305 is fixedly installed at the bottom of the end of the positioning clamp column 303 away from the top spring 304, and the lap block 3 The bottom of 05 is fitted with the top of a positioning clamp column 303 adjacent to the bottom of the positioning clamp column 303, and the overlap block 305 is used to strengthen the upper and lower adjacent positioning clamp columns 303. The outer surfaces of the two sides of the movable positioning clamp 301 that are perpendicular to the path opened by the embedded groove 102 are fixedly installed with push-pull bevel strips 306. A telescopic groove 104 is opened at the top of the lower shell body 101, and a pushing square rod 307 is slidably installed inside the telescopic groove 104. A pushing wheel 308 is rotatably installed at the bottom of the pushing square rod 307. The bottom of the outer wall of the pushing wheel 308 abuts against the top of the pushing bevel strip 306. A force handle 309 is fixedly installed on the top of the pushing square rod 307. The pushing square rod 307 is used to push the pushing bevel strip 306 to move together with the movable positioning clamp 301.

[0042] Specifically, when the buckling groove 202 is buckled downward, the top wall of the groove 2001 contacts the top of the force-bearing handle 309, pushing the force-bearing handle 309 downward, and the downward movement of the force-bearing handle 309 further drives the pushing square rod 307 to move downward along the inner wall of the telescopic groove 104, pushing the push wheel 308 downward, and the downward movement of the push wheel 308 will produce a wedge force effect with the push-pull inclined strip 306, further pushing the two movable positioning clips 301 located on both sides of the embedded groove 102 toward the middle, and the two movable positioning clips 301 are pushed toward the middle The top spring 304 moves to drive the positioning clamp column 303 to move together. When the positioning clamp columns 303 on both sides of the embedded groove 102 touch the outer wall of the wire inside the embedded groove 102, as the movable positioning clamp 301 continues to move, it will slide into the inside of the slide groove 302, thereby compressing the top spring 304 to generate a rebound force, so that the positioning clamp column 303 is tightly pressed against the outer wall of the wire through the rebound force of the top spring 304, thereby providing a positioning effect on both sides of the wire, so that the wire will not be blocked during the process of the puncture needle 500 puncturing the wire. The puncture needle 500 moves sideways to ensure the accuracy of puncture, and the positioning clamp column 303 located at the top of the wire does not contact the outer wall of the wire, so during the movement, it abuts against the positioning clamp column 303 moving in the opposite direction, thereby blocking the top of the wire. When the puncture needle 500 punctures the wire upward, the positioning clamp column 303 blocks the top of the wire, which can prevent the wire from being forced to move upward, thereby ensuring the smoothness of puncture. Compared with the existing means, it avoids the problem of inaccurate voltage measurement due to the puncture needle 500 not puncturing in place. The problem occurs, and since the bottom spacing between the upper and lower positioning clamps 303 is the unit value of a national standard wire model, it can be used to position wires of different thicknesses, thereby improving the adaptability of use. In addition, since the overlapping block 305 at the end of the upper positioning clamp 303 provides downward support for the top of the next positioning clamp 303, the upper and lower multiple positioning clamps 303 can form a connected effect, thereby improving the overall bending resistance of the positioning clamp 303 and avoiding the risk of the positioning clamp 303 bending upward due to excessive force.

[0043] Reference Fig. 9 As shown, a guide groove 3010 is formed through the movable positioning clamp 301 and a side surface close to the positioning clamp column 303, and an aluminum alloy guide rod 3011 is fixedly installed inside the lower shell 101. The inner wall of the guide groove 3010 and the outer wall of the aluminum alloy guide rod 3011 are slidably installed, and the aluminum alloy guide rod 3011 is used to guide the movable positioning clamp 301.

[0044] Specifically, by setting up the sliding connection between the aluminum alloy guide rod 3011 and the guide groove 3010, the movable positioning clamp 301 can be provided with a precise guiding effect, ensuring the stability of the movement of the movable positioning clamp 301, that is, ensuring the positioning effect of the positioning clamp column 303 on the guide wire, thereby improving the puncture accuracy of the puncture needle 500.

[0045] Reference Fig.10 As shown, a return spring 3012 is fixedly installed on one side of the movable positioning clamp 301 away from the positioning clamp column 303, the return spring 3012 is located at the bottom of the aluminum alloy guide rod 3011, and one end of the return spring 3012 away from the movable positioning clamp 301 is fixedly connected to the inner wall of one side of the lower shell 101, and the return spring 3012 is used for resetting the movable positioning clamp 301.

[0046] Specifically, when the two movable positioning clips 301 located on both sides of the embedded groove 102 move toward each other, the reset spring 3012 connected to the movable positioning clip 301 is elastically pulled up, prompting the reset spring 3012 to generate a rebound force. Therefore, when the detection is completed, the upper shell 201 is removed from the top of the lower shell 101. The rebound force of the reset spring 3012 can automatically reset the movable positioning clip 301, which is convenient for the next use.

[0047] Reference Figure 1 , Figure 2 , Figure 7 As shown, inner thread holes 105 are provided at the four corners of the top of the lower shell 101, and insertion holes 203 are provided at the four corners of the top of the upper shell 201. The insertion holes 203 extend through to the bottom of the upper shell 201, and the interiors of the insertion holes 203 are movably connected with combination screws 1000, which extend through to the bottom of the upper shell 201, and the outer wall of the combination screw 1000 is threadedly connected with the inner wall of the inner thread hole 105. The combination screw 1000 is used for the combined installation of the lower shell 101 and the upper shell 201.

[0048] Specifically, the upper shell 201 is buckled on the top of the lower shell 101, and at the same time, the four combination screws 1000 are aligned with the four internal thread holes 105, and the four combination screws 1000 are screwed into the inner walls of the four internal thread holes 105 using a screwdriver, and then the upper shell 201 is pressed down to move under the action of the thread thrust between the four combination screws 1000 and the four internal thread holes 105, so that the upper shell 201 and the lower shell 101 are buckled together. At the same time, due to the action of the thread force between the combination screws 1000 and the internal thread holes 105, it can be ensured that the lower shell 101 and the upper shell 201 will not be easily separated after buckling.

[0049] When an outdoor combined mutual inductor of the present invention is working, the wire is passed through the inside of the buried groove 102, and then the upper shell 201 is buckled on the top of the lower shell 101, while ensuring that the four combination screws 1000 are aligned with the four inner thread holes 105, and the four combination screws 1000 are screwed into the inner walls of the four inner thread holes 105 using a screwdriver, and then the upper shell 201 is pressed downward under the thread thrust between the four combination screws 1000 and the four inner thread holes 105 to move until the buckling groove 202 is buckled on the top of the buried groove 102. At this time, the wire is located inside the "circular cavity" formed by the buried groove 102 and the buckling groove 202. The buckling between the shell 201 and the lower shell 101 causes the upper contact pole 800 to contact the lower contact pole 900 to generate a conductive effect, and the current wound on the outer winding coil of the lower semicircular magnetic core 600 is transmitted to the outer winding coil of the upper semicircular magnetic core 700, so that the lower semicircular magnetic core 600 and the upper semicircular magnetic core 700 are combined into a circular detection structure, and the wire located between the embedded groove 102 and the buckling groove 202 is detected. The puncture needle 500 is lifted upward by the output rod of the electric push rod 400, so that the top of the puncture needle 500 extends upward from the inside of the puncture hole 1001 and pierces the inside of the wire to perform voltage detection;

[0050] When the locking cam 306 is in the closed position, the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, so that the locking cam 306 is in the closed position, and the locking cam 306 is in the closed position, The positioning clamping column 303 is tightly against the outer wall of the wire, thereby providing a positioning effect for both sides of the wire, so that the wire will not move sideways during the process of the puncture needle 500 puncturing the wire, thereby ensuring the accuracy of the puncture, and the positioning clamping column 303 located at the top of the wire does not contact the outer wall of the wire, so during the movement, it abuts against the positioning clamping column 303 moving in the opposite direction, thereby blocking the top of the wire, so that when the puncture needle 500 punctures the wire upward, the horizontal block of the positioning clamping column 303 on the top of the wire can prevent the wire from being forced to move upward, thereby ensuring the smoothness of the puncture. Compared with the existing means, the problem of inaccurate voltage measurement due to the inadequate puncture of the puncture needle 500 is avoided, and since the bottom spacing of the upper and lower positioning clamping columns 303 is one model unit value of the national standard wire, it can be used to position wires of different thicknesses, thereby improving the adaptability of use.
