[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-2As shown in the figure, an embodiment of the present invention provides a comprehensive electrical inspection tester. Generally, a comprehensive electrical inspection tester typically includes a main unit responsible for data processing and result display, voltage test leads for connecting the tester and the circuit under test to measure voltage values, a clamp meter body 1 for non-invasive current measurement, a signal generating device for generating test signals to help verify the performance of electricity meters and other electrical equipment, and a storage function that supports large-capacity memory cards and built-in memory for convenient saving of test data and results. The clamp meter body 1 includes a detection area and a grip area, with a handle installed in the grip area, and the wire to be tested is located between the detection areas.

[0031] like Figures 1-2 As shown, a protective mechanism is installed outside the detection area of ​​the clamp meter body 1. The protective mechanism can not only protect the detection area and avoid damage to the detection area from impacts, thus affecting the service life of the clamp meter body 1, but also reduce the adhesion of impurities and dust to the detection area to a certain extent, which could lead to poor contact between the clamp meter and 102 and affect the accuracy of the measurement.

[0032] like Figures 3-4 As shown, the protective mechanism includes a dust cover 2, with a first fixing rod 201 installed at one end of the dust cover 2. A first dust-absorbing cotton 202 is installed on the outside of the first fixing rod 201, and a detachable component for replacing the first dust-absorbing cotton 202 is installed on the first fixing rod 201. The dust cover 2 covers the detection area of ​​the clamp meter body 1, reducing dust and impurities at the source, thereby reducing the possibility of impurities and dust adhering to the detection area. When the clamp meter body 1 is finished using and needs to be returned to its interior, impurities and dust inevitably adhere to the detection area of ​​the clamp meter body 1. The first dust-absorbing cotton 202 wrapped around the outer wall of the first fixing rod 201 can absorb dust and impurities by wiping the surface of the detection area, reducing to a certain extent the possibility of impurities and dust causing wear to the detection area of ​​the clamp meter body 1, or even causing damage to the clamp meter body 1. When the first dust removal cotton 202 has absorbed a lot of impurities and dust, affecting its cleaning effect, the user can remove and replace the dirty first dust removal cotton 202 through the detachable component to ensure its cleaning effect.

[0033] like Figures 2-4As shown, the detachable component includes a second fixing rod 203 for mounting the first dust removal cotton 202. The second fixing rod 203 is mounted on the first fixing rod 201. The first fixing rod 201 has a first mounting groove 204 that matches the second fixing rod 203. A reinforcing component is mounted on the detachable component. First, remove the second fixing rod 203, wrap a piece of the first dust removal cotton 202 around the first fixing rod 201, and then insert both ends of the first dust removal cotton 202 into the first mounting groove 204 through the second fixing rod 203 to fix the first dust removal cotton 202. This prevents the first dust removal cotton 202 from moving with the detection area during wiping, thus affecting the wiping effect of the first dust removal cotton 202.

[0034] like Figures 3-4 As shown, the reinforcement component includes a first limiting block 205, which is fixedly connected to the first fixing rod 201. A second limiting block 206 is installed on the first limiting block 205 and fixedly connected to one end of the second fixing rod 203. The first limiting block 205 has a second mounting groove 207 that matches the second limiting block 206. The dust cover 2 has a limiting groove 208 that matches the first limiting block 205 and the second limiting block 206. The reinforcement component further secures the second fixing rod 203, preventing it from slipping out of the first mounting groove 204 and causing the first dust removal cotton 202 to fall off.

[0035] Specifically, the first fixing rod 201 is rotated until the first mounting groove 204 is aligned with the limiting groove 208. After the first dust removal cotton 202 is wrapped around the first fixing rod 201, the second limiting block 206 is inserted into the second mounting groove 207. At this time, the second fixing rod 203 is pushed into the first mounting groove 204 to fix the first dust removal cotton 202. Then, the first limiting block 205 and the second mounting groove 207 are rotated 180 degrees until the first mounting groove 204 and the limiting groove 208 are misaligned and the first dust removal cotton 202 faces the detection area.

[0036] Preferably, when the first dust removal cotton 202 is too thick or too thin and cannot be fixed by inserting the second fixing rod 203 into the first mounting groove 204, the reinforcement component can fix both ends of the first dust removal cotton 202 so that different specifications of the first dust removal cotton 202 can be used.

[0037] like Figure 4As shown, a dust cover 209 is installed at the end of the dust cover 2 near the detection area. The dust cover 209 has an inlet / outlet 210 that matches the clamp meter body 1. The dust cover 209 is made of transparent PVC. When the user needs to lower the dust cover 2 to test 102, the detection area at one end of the clamp meter body 1 enters and exits the dust cover 2 through the inlet / outlet 210. The highly flexible transparent PVC sheet can better fit the outer wall of the clamp meter body 1, preventing dust and impurities from entering the dust cover 2 through gaps to a certain extent.

[0038] like Figure 5 As shown, two sets of T-shaped support frames 211 are symmetrically installed inside the dust cover 2. Rollers 212 matching the clamp meter body 1 are mounted on the T-shaped support frames 211. The clamp meter body 1 is generally wider at both ends and narrower in the middle. Initially, the dust cover 2 is located in the detection area of ​​the clamp meter body 1. When the user squeezes the grip area to bring the two handles of the clamp meter body 1 closer together, the detection ends of the detection area move away from each other. Because the width of the detection area increases, the distance between the two sets of T-shaped support frames 211 remains unchanged, and the dust cover 2 tends to move towards the narrower end. The T-shaped support frames 211 then move the dust cover 2 towards the middle of the clamp meter body 1, exposing the detection area. This allows the user to complete the installation of the clamp meter body 1 with one hand, improving the convenience of inspection.

[0039] When the friction between the T-shaped support frame 211 and the roller 212, and between the roller 212 and the surface of the clamp meter body 1 is large, affecting the movement of the dust cover 2, the staff can independently select a suitable existing lubricant to maintain the normal movement of the dust cover 2.

[0040] like Figures 1-6 As shown, a wire wiping assembly is installed at one end of the clamp meter body 1 near the hand grip area. Impurities between the detection area and 102 can originate not only from the detection area but also from outside 102. The wire wiping assembly can remove impurities and dust from the outer wall of 102, minimizing the increase in contact resistance caused by impurities and dust, which could lead to higher measured values.

[0041] like Figure 6 As shown, the wire wiping assembly includes two symmetrically arranged clamping rods 3. A second dust removal cotton 301, matching the 102, is installed at the inner end of each clamping rod 3. When the operator needs to clamp the 102 using the clamp meter body 1, the second dust removal cotton 301 is placed on both sides of the 102, the operator holds the grip area, and brings the second dust removal cotton 301 close to the 102, wiping along the 102. At this time, with the cooperation of the T-shaped support frame 211 and the roller 212, the dust cover 2 moves towards the center of the clamp meter body 1.

[0042] like Figure 6 As shown, a rubber protective layer 101 is installed on the side of the clamp meter body 1 closest to the user's hand. The rubber protective layer 101 makes it easier for the operator to hold the clamp meter body 1 securely.

[0043] like Figure 7 As shown, when 102 needs to be clamped after wiping, flip the arm so that the detection area is aligned with 102, and release the hand holding the grip area to clamp the wire to be tested.

[0044] like Figures 1 to 7 As shown, the dust cover 2 has an acrylic square outer frame. The transparent acrylic square outer frame allows staff to easily observe the condition of the first dust removal cotton 202 and replace it promptly.

[0045] During use, when the user uses the power inspection and testing instrument to check and test the power system, and needs to use the clamp meter body 1 to clamp 102, squeeze the handle in the hand grip area inward to open the detection area. The protective mechanism moves towards the hand grip area to expose the detection area. The user moves the clamp meter body 1 to both sides of 102, releases, clamps 102, and then uses the product host to check.

[0046] When dust and impurities adhere to the outside of 102 and need to be wiped, before clamping 102, point the clamping rod 3 toward 102, with 102 positioned between the second dust removal cotton 301. Hold the handle, bring the second dust removal cotton 301 close to 102, move the handle, and wipe 102, thereby avoiding the influence of dust and impurities on the inspection results to a certain extent.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
