Description

Technical Field

[0001] This application relates to the field of high voltage testing technology, and in particular to a high voltage testing wiring clamp. Background Technology

[0002] High-voltage testing is an important means of diagnosing and analyzing equipment operating conditions. The location and timing of the test wiring directly affect the accuracy of the test data and the efficiency of the test, thus impacting the entire work process. During high-voltage testing, wiring pliers are generally used to connect the high-voltage wire to the test equipment.

[0003] A wiring clamp typically consists of two clamping bodies, at least one of which is movable, allowing the two bodies to move closer together or further apart, thus clamping and releasing the high-voltage line. Currently, the movement of the clamping bodies of wiring clamps is mostly achieved manually by the tester, and the clamping force is determined by the tester's subjective judgment.

[0004] This method of clamping, relying on the operator's own sense of touch, makes it difficult to control the clamping force. When the clamping force is too small, the clamping pliers may fall off the high-voltage line; when the clamping force is too large, the pliers may damage the wire. Moreover, different operators have different senses and perceive different clamping forces. Based on this, this application proposes a high-voltage testing clamping pliers. Utility Model Content

[0005] This application provides a high-voltage test wiring clamp that uses a clamping motor to bring the upper and lower clamps closer and further apart, eliminating the need for manual clamping. The clamping force is detected by a pressure sensor, and when the preset pressure is reached, the clamping motor stops and no longer drives the upper clamp to move. This ensures that the high-voltage test wiring clamp is securely clamped on the high-voltage line, and prevents the clamping force from being too weak or too strong, thus avoiding the wiring clamp from falling off or damaging the high-voltage line.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A high-voltage test wiring clamp includes a support rod, an upper clamp body, a lower clamp body, and a controller. The upper end of the support rod has a vertical sliding groove, within which a clamping screw is rotatably connected. The clamping screw is driven by a clamping motor. The upper clamp body is vertically slidably connected to the vertical sliding groove and threadedly engaged with the clamping screw. The upper clamp body has an upper clamping groove containing a pressure sensor. The lower clamp body is fixed within the vertical sliding groove and has a lower clamping groove opposite to the upper clamping groove. The clamping motor and the pressure sensor are both electrically connected to the controller. The controller is configured to stop the clamping motor from rotating when the pressure sensor detects that the pressure has reached a preset pressure.

[0008] During use, the tester holds the support rod and places the upper and lower clamps at the high-voltage line, positioning the high-voltage line between the upper and lower clamps. Then, the clamping motor is started, and the clamping motor drives the upper clamp to gradually approach the lower clamp through the clamping screw. The pressure detected by the pressure sensor on the upper clamp gradually increases until the pressure reaches the preset pressure value. The controller then stops the clamping motor, thus clamping the high-voltage line.

[0009] Compared to existing technologies, this high-voltage test clamp uses a clamping motor to bring the upper and lower clamps closer and further apart, eliminating the need for manual clamping. Furthermore, the clamping force is detected by a pressure sensor. When the preset pressure is reached, the clamping motor stops and no longer drives the upper clamp to move, ensuring that the entire high-voltage test clamp is securely clamped on the high-voltage line. This prevents the clamping force from being too weak or too strong, thus avoiding the clamp from falling off or damaging the high-voltage line.

[0010] In one embodiment of this application, the pressure sensor is a thin-film pressure sensor.

[0011] In one embodiment of this application, the upper clamp body is provided with a plurality of upper clamping grooves, the plurality of upper clamping grooves are spaced apart along the length direction of the upper clamp body, and the size of the plurality of upper clamping grooves decreases sequentially in the direction away from the vertical slide groove.

[0012] In one embodiment of this application, the number of pressure sensors is equal to the number of upper clamping slots, and the multiple pressure sensors are arranged one-to-one in the multiple upper clamping slots.

[0013] In one embodiment of this application, a selector switch is provided on the support rod, and multiple pressure sensors are electrically connected to the controller through the selector switch, and at the same time, the selector switch realizes the electrical connection between one pressure sensor and the controller.

[0014] In one embodiment of this application, the support rod includes an inner cylinder, an outer cylinder, and a lifting screw. The vertical slide groove is disposed at the top of the inner cylinder. The lifting screw is rotatably connected to the outer cylinder and is drivenly connected to a lifting motor. The lifting motor is disposed at the bottom of the outer cylinder. The inner wall of the inner cylinder is provided with an internal thread, which cooperates with the lifting screw. The inner cylinder is vertically slidably connected to the outer cylinder.

[0015] In one embodiment of this application, the inner wall of the outer cylinder is provided with a vertical guide groove, and the outer wall of the inner cylinder is provided with a guide block, the guide block cooperating with the vertical guide groove. Attached Figure Description

Figure 5 This is a cross-sectional view of the support rod used in a high-voltage test wiring clamp provided in an embodiment of this application.

[0029] Embodiments of this application provide a high-voltage test wiring clamp, such as... Figure 1 and Figure 2 As shown, it includes a support rod 100, an upper clamp body 300, a lower clamp body 400, and a controller (not shown in the figure). The support rod 100 is a structure for mounting and supporting other components. The upper clamp body 300 and the lower clamp body 400 are components for clamping the high-voltage line 010. The controller controls the electronic components to achieve automatic control.

[0030] like Figure 1 and Figure 3As shown, the upper end of the support rod 100 is provided with a vertical slide groove 200. The vertical slide groove 200 is generally rectangular in shape. A clamping screw 210 is rotatably connected inside the vertical slide groove 200. The clamping screw 210 is vertically arranged and is driven by a clamping motor 220. When the clamping motor 220 is started, it can drive the clamping screw 210 to rotate, thereby driving the components on the clamping screw 210 to move up and down.

[0031] like Figure 1 and Figure 2 As shown, the upper clamp body 300 is vertically slidably connected within the vertical slide groove 200 and threadedly engaged with the clamping screw 210. The side wall of the upper clamp body 300 abuts against the inner wall of the vertical slide groove 200 to prevent rotation of the upper clamp body 300. When the clamping screw 210 rotates, it can drive the upper clamp body 300 to move up and down. Figure 4 As shown, the upper clamp body 300 is provided with an upper clamping groove 310, which is a semi-circular groove. A pressure sensor 320 is provided in the upper clamping groove 310, which can detect the pressure between the upper clamping groove 310 and the high-voltage line 010.

[0032] like Figure 1 As shown, the lower clamp body 400 is fixed in the vertical slide groove 200. The lower clamp body 400 is provided with a lower clamping groove, which is also a semi-circular groove. The lower clamping groove is opposite to the upper clamping groove 310, and the upper clamping groove 310 is close to the lower clamping groove, so as to clamp the high voltage line 010. The structure of the lower clamp body 400 is the same as that of the upper clamp body 300.

[0033] The clamping motor 220 and the pressure sensor 320 are both electrically connected to the controller. When the clamping motor 220 is started, the upper clamp 300 gradually approaches the lower clamp 400, and the pressure between the upper clamping groove 310 and the high-voltage line 010 gradually increases. When the pressure sensor 320 detects that the pressure has reached the preset pressure, it means that the upper clamp 300 and the lower clamp 400 have clamped the high-voltage line 010 well. The controller controls the clamping motor 220 to stop rotating, and the upper clamp 300 no longer moves.

[0034] During use, the tester holds the support rod 100 and places the upper clamp 300 and lower clamp 400 at the high-voltage line 010, so that the high-voltage line 010 is located between the upper clamp 300 and the lower clamp 400. Then, the clamping motor 220 is started. The clamping motor 220 drives the upper clamp 300 to gradually approach the lower clamp 400 through the clamping screw 210. The pressure detected by the pressure sensor 320 on the upper clamp 300 gradually increases until the pressure reaches the preset pressure value. The controller controls the clamping motor 220 to stop, thus achieving the clamping of the high-voltage line 010.

[0035] Compared to existing technologies, this high-voltage test wiring clamp uses a clamping motor 220 to move the upper clamp body 300 and the lower clamp body 400 closer and further apart, eliminating the need for manual clamping. Moreover, the clamping force is detected by a pressure sensor 320. When the preset pressure is reached, the clamping motor 220 stops and no longer drives the upper clamp body 300 to move, ensuring that the entire high-voltage test wiring clamp is well clamped on the high-voltage line 010. Furthermore, it avoids situations where the clamping force is too weak or too strong, preventing the wiring clamp from falling off or damaging the high-voltage line.

[0036] In some embodiments, such as Figure 4 As shown, the pressure sensor 320 is a thin-film pressure sensor. The detection part of the thin-film pressure sensor 320 is a thin-film structure, which can be fitted and installed onto the groove wall of the upper clamping groove 310, making it easy to install into the upper clamping groove 310.

[0037] In some embodiments, such as Figure 4 As shown, the upper clamp body 300 is provided with multiple upper clamping slots 310, which are spaced apart along the length of the upper clamp body 300. The dimensions of the multiple upper clamping slots 310 decrease sequentially in the direction away from the vertical slide groove 200, allowing the upper clamp body 300 to clamp high-voltage wires 010 of various diameters, thus improving its applicability. Naturally, the lower clamp body 400 is also configured in this manner to correspond with the upper clamp body 300, which will not be described in detail here.

[0038] In some embodiments, such as Figure 4 As shown, the number of pressure sensors 320 is equal to the number of upper clamping slots 310, with multiple pressure sensors 320 being arranged one-to-one in multiple upper clamping slots 310. Naturally, these pressure sensors 320 are all electrically connected to the controller. Each upper clamping slot 310 is equipped with one pressure sensor 320, enabling pressure detection when clamping each type of high-voltage wire 010 and transmitting the detected pressure value to the controller.

[0039] In some embodiments, the support rod 100 is equipped with a selector switch (not shown in the figure). Multiple pressure sensors 320 are electrically connected to the controller via the selector switch, and the selector switch simultaneously connects one pressure sensor 320 to the controller. That is, when clamping the high-voltage wire 010, only one upper clamping slot 310 is clamping the high-voltage wire 010, and only the pressure sensor 320 in this clamping upper clamping slot 310 is electrically connected to the controller and controls the operation of the clamping motor 220 through the controller. The pressure sensors 320 in the other upper clamping slots 310 that are not clamping are not electrically connected to the controller, and therefore do not control the operation of the clamping motor 220 through the controller.

[0040] In some embodiments, such as Figure 5As shown, the support rod 100 includes an inner cylinder 110, an outer cylinder 120, and a lifting screw 130. A vertical slide groove 200 is located at the top of the inner cylinder 110 and can move with the inner cylinder 110. The lifting screw 130 is rotatably connected inside the outer cylinder 120 and is driven by a lifting motor 140, which is installed at the bottom of the outer cylinder 120. The inner wall of the inner cylinder 110 has an internal thread that engages with the lifting screw 130. The inner cylinder 110 is vertically slidably connected to the outer cylinder 120. When the lifting motor 140 is started, it can drive the lifting screw 130 to rotate, thereby causing the inner cylinder 110 to slide up and down along the outer cylinder 120, realizing the extension and retraction of the support rod 100, thus changing the length of the entire support rod 100 and changing the height of the vertical slide groove 200.

[0041] In some embodiments, such as Figure 5 As shown, the inner wall of the outer cylinder 120 is provided with a vertical guide groove 121, and the outer wall of the inner cylinder 110 is provided with a guide block 111. The guide block 111 cooperates with the vertical guide groove 121 to restrict the rotation of the inner cylinder 110 relative to the outer cylinder 120, so as to ensure that the inner cylinder 110 can move up and down and slide.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
