Description

Technical Field

[0001] This application relates to the field of grounding plate testing technology, and for example to a fixture for testing the resistance of silver-plated grounding plates. Background Technology

[0002] Currently, silver plating is widely used in electrical equipment manufacturing, communications industry, and instrumentation. Silver plating is easy to polish and possesses good thermal conductivity, electrical conductivity, and weldability. The conductivity of silver-plated grounding plates is a crucial indicator affecting their usability. Resistance testing of silver-plated grounding plates is an important means of ensuring they meet usage requirements.

[0003] The existing resistance test for silver-plated grounding plates involves clamping test clips at both ends of the silver-plated grounding plate, electrically connecting the test clips to the silver-plated grounding plate, and performing an energized test to determine whether the silver-plated grounding plate meets the usage requirements.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The location where the silver-plated grounding plate is clamped and the location of the test connection point are relatively random, making it difficult to effectively clamp them at the same position on the silver-plated grounding plate, which results in a relatively large error in the test results.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a fixture for testing the resistance of a silver-plated grounding sheet. The fixture can be clamped at the same position on the silver-plated grounding sheet, resulting in relatively small testing errors during the testing process.

[0009] In some embodiments, the fixture for testing the resistance of a silver-plated grounding sheet includes: a first fixed base, a second fixed base, a first electrical clamp, and a second electrical clamp. The first fixed base has a first abutment surface; the second fixed base is located on one side of the first fixed base and has a second abutment surface opposite to the first abutment surface; the first electrical clamp is disposed between the first abutment surface and the second abutment surface and is fixedly connected to the first fixed base, for clamping one end of the silver-plated grounding sheet; the second electrical clamp is disposed between the first abutment surface and the second abutment surface and is fixedly connected to the second fixed base, for clamping the other end of the silver-plated grounding sheet.

[0010] Optionally, the first fixing base includes: a first base and a first support arm. The first support arm is inserted into the top of the first base and has a first abutment surface, and the first electric clamp is fixedly connected to the first support arm.

[0011] Optionally, the upper side wall of the first base is provided with a plurality of first slots, the plurality of first slots are arranged sequentially along a direction perpendicular to the first abutment surface, and the lower end of the first support arm is provided with a first plug, the first plug being inserted into one of the first slots.

[0012] Optionally, the first base and / or the first support arm are made of insulating material.

[0013] Optionally, a first connecting rod is fixedly provided on the side of the first support arm adjacent to the first contact surface, and the first connecting rod is fixedly connected to the first electric clamp.

[0014] Optionally, the first fixed seat and the second fixed seat are connected by a sliding connector, which includes a slide groove and a slide rod, one of which is disposed on the first fixed seat and the other is disposed on the second fixed seat.

[0015] Optionally, one end of the slide rod facing the slide groove is connected to one end of the spring, and the other end of the spring is connected to the inner wall of the slide groove.

[0016] Optionally, both ends of the spring are hooked to hooks, one of which is fixedly connected to the end of the slide bar facing the slide groove, and the other is fixedly connected to the inner wall of the slide groove.

[0017] Optionally, the first electrical clamp is provided with a first wiring hole.

[0018] Optionally, when the first fixing seat and the second fixing seat abut against each other, there is a gap between the first abutting surface and the second abutting surface.

[0019] The fixture for testing the resistance of silver-plated grounding plates provided in this disclosure can achieve the following technical effects:

[0020] The two ends of the silver-plated grounding plate are clamped onto the first and second clamps, respectively. The relative positions of the first and second fixing bases are adjusted so that the first contact surface abuts against the end of the silver-plated grounding plate clamped by the first clamp, and the second contact surface abuts against the end of the silver-plated grounding plate clamped by the second clamp. The first and second contact surfaces together limit the movement of the silver-plated grounding plate, ensuring that both clamps are positioned at the same location, resulting in a relatively small error in the test results.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figure 1-2As shown, this embodiment of the present disclosure provides a fixture for testing the resistance of a silver-plated grounding sheet, comprising: a first fixing base 100, a second fixing base 200, a first clamp 300, and a second clamp 400. The first fixing base 100 has a first abutment surface 101; the second fixing base 200 is located on one side of the first fixing base 100 and has a second abutment surface 201 opposite to the first abutment surface 101; the first clamp 300 is disposed between the first abutment surface 101 and the second abutment surface 201 and is fixedly connected to the first fixing base 100, for clamping one end of the silver-plated grounding sheet; the second clamp 400 is disposed between the first abutment surface 101 and the second abutment surface 201 and is fixedly connected to the second fixing base 200, for clamping the other end of the silver-plated grounding sheet.

[0039] Using the fixture for testing the resistance of a silver-plated grounding sheet provided in this embodiment, the two ends of the silver-plated grounding sheet are respectively clamped onto the first clamp 300 and the second clamp 400. The relative positions of the first fixing base 100 and the second fixing base 200 are adjusted so that the first abutment surface 101 abuts against the end of the silver-plated grounding sheet clamped by the first clamp 300, and the second abutment surface 201 abuts against the end of the silver-plated grounding sheet clamped by the second clamp 400. The first abutment surface 101 and the second abutment surface 201 together limit the position of the silver-plated grounding sheet, ensuring that the first clamp 300 and the second clamp 400 are both clamped at the same position on the silver-plated grounding sheet, resulting in a relatively small error in the test results.

[0040] Understandably, the distance between the first contact surface 101 and the second contact surface 201 can be adjusted to be equal to the length of the silver-plated grounding piece, and then the silver-plated grounding piece can be clamped between the first contact surface 101 and the second contact surface 201 onto the first electric clamp 300 and the second electric clamp 400.

[0041] Combination Figure 3 As shown, optionally, the first fixed base 100 includes a first base 110 and a first support arm 120. The first support arm 120 is inserted into the top of the first base 110 and has a first abutment surface 101. The first electric clamp 300 is fixedly connected to the first support arm 120. Thus, the height of the first support arm 120 is relatively high, and when the first electric clamp 300 is installed on the first support arm 120, the height of the first electric clamp 300 is also relatively high. The height at which the first electric clamp 300 holds the silver-plated grounding plate from the ground or tabletop is relatively high, making it convenient for operators to hold the silver-plated grounding plate.

[0042] Optionally, the length of the first support arm 120 is greater than the length of the first base 110. In this way, the height of the first support arm 120 is relatively high, making it easier for the operator to clamp the silver-plated grounding plate.

[0043] Optionally, the projected area of ​​the first support arm 120 facing the horizontal plane is smaller than the projected area of ​​the first base 110 facing the horizontal plane. In this way, the contact area between the first base 110 and the ground or tabletop is relatively large, resulting in relatively high stability.

[0044] Optionally, the upper sidewall of the first base 110 is provided with a plurality of first slots 111, which are arranged sequentially along a direction perpendicular to the first abutment surface 101. The lower end of the first support arm 120 is provided with a first insert 121, which is inserted into one of the first slots 111. In this way, the first insert 121 is inserted into the first slots 111 at different positions to adjust the interval between the first support arm 120 and the second fixed seat 200, thereby adjusting the interval between the first abutment surface 101 and the second abutment surface 201. This can meet the clamping test requirements of silver-plated grounding sheets of different sizes, and the compatibility range is relatively large.

[0045] Optionally, two first slots 111 are provided. Thus, the first insert 121 is inserted into the first slots 111 at different positions to adjust the distance between the first support arm 120 and the second fixing seat 200, thereby adjusting the distance between the first abutment surface 101 and the second abutment surface 201. This allows for clamping tests on silver-plated grounding sheets of different sizes, providing a relatively wide range of compatibility.

[0046] Optionally, the projected area of ​​the first insert 121 facing the lower side of the first support arm 120 is smaller than the area of ​​the lower side of the first support arm 120. In this way, when the first insert 121 is inserted into the first slot 111, the first support arm 120 can shield the first insert 121, resulting in relatively good overall integrity.

[0047] Optionally, the first base 110 and / or the first support arm 120 are made of insulating material. In this way, since the silver-plated grounding sheet is being tested for electrical continuity, the risk of leakage is relatively low and the safety is relatively high during the testing process, thanks to the insulating material used in the first base 110 and / or the first support arm 120.

[0048] Optionally, the first base 110 and / or the first support arm 120 are made of rubber material. This ensures good insulation performance of the first base 110 and / or the first support arm 120, since the silver-plated grounding sheet is being tested for electrical continuity. During the silver-plated grounding sheet test, the risk of leakage is relatively low, and the safety is relatively high.

[0049] Understandably, the first base 110 and / or the first support arm 120 may also be made of other insulating materials such as plastic.

[0050] Optionally, a first connecting rod 130 is fixedly provided on the side of the first support arm 120 adjacent to the first contact surface 101, and the first connecting rod 130 is fixedly connected to the first electric clamp 300. In this way, the contact area between the first connecting rod 130 and the first support arm 120 is relatively large, and the connection stability is relatively high.

[0051] Optionally, the first connecting rod 130 is made of insulating material. This ensures good insulation performance of the first connecting rod 130, which is made of insulating material, since the silver-plated grounding sheet is being tested for electrical continuity. During the silver-plated grounding sheet test, the risk of leakage is relatively low, and the safety is relatively high.

[0052] Optionally, the second mounting base 200 includes a second base 210 and a second support arm 220. The second support arm 220 is inserted into the top of the second base 210 and has a second abutment surface 201. The second electric clamp 400 is fixedly connected to the second support arm 220. Thus, the second support arm 220 has a relatively high height, and when the second electric clamp 400 is mounted on the second support arm 220, the second electric clamp 400 also has a relatively high height. The second electric clamp 400 holds the silver-plated grounding plate at a relatively high height from the ground or tabletop, facilitating the operator's gripping of the silver-plated grounding plate.

[0053] Optionally, the length of the second support arm 220 is greater than the length of the second base 210. This makes the height of the second support arm 220 relatively high, facilitating the operator to clamp the silver-plated grounding plate.

[0054] Optionally, the projected area of ​​the second support arm 220 facing the horizontal plane is smaller than the projected area of ​​the second base 210 facing the horizontal plane. In this way, the contact area between the second base 210 and the ground or tabletop is relatively large, resulting in relatively high stability.

[0055] Optionally, the upper sidewall of the second base 210 is provided with a plurality of second slots 211, which are arranged sequentially along a direction perpendicular to the second abutment surface 201. The lower end of the second support arm 220 is provided with a second insert 221, which is inserted into one of the second slots 211. In this way, the second insert 221 is inserted into the second slots 211 at different positions to adjust the interval between the second support arm 220 and the first fixed base 100, thereby adjusting the interval between the second abutment surface 201 and the first abutment surface 101. It also cooperates with the first slot 111 and the first insert 121 to meet the clamping test of silver-plated grounding plates of different sizes, and the adaptation range is relatively large.

[0056] Optionally, two second slots 211 are provided. In this way, the second insert 221 is inserted into the second slots 211 at different positions to adjust the interval between the second support arm 220 and the first fixing seat 100, so as to meet the clamping test of silver-plated grounding plates of different sizes, and the adaptation range is relatively large.

[0057] Optionally, the projected area of ​​the second insert 221 toward the lower side of the second support arm 220 is smaller than the area of ​​the lower side of the second support arm 220. In this way, when the second insert 221 is inserted into the second slot 211, the second support arm 220 can shield the second insert 221, resulting in relatively good overall integrity.

[0058] Optionally, the second base 210 and / or the second support arm 220 are made of insulating material. In this way, since the silver-plated grounding sheet is being tested for electrical continuity, the risk of leakage is relatively low and the safety is relatively high during the testing process, thanks to the insulating material used in the second base 210 and / or the second support arm 220.

[0059] Optionally, the second base 210 and / or the second support arm 220 are made of rubber material. This ensures good insulation performance of the second base 210 and / or the second support arm 220, since the silver-plated grounding sheet is being tested for electrical continuity. During the silver-plated grounding sheet test, the risk of leakage is relatively low, and the safety is relatively high.

[0060] Understandably, the second base 210 and / or the second support arm 220 may also be made of other insulating materials such as plastic.

[0061] Optionally, a second connecting rod 230 is fixedly provided on the side of the second support portion adjacent to the second contact surface 201, and the second connecting rod 230 is fixedly connected to the second electric clamp 400. In this way, the contact area between the second connecting rod 230 and the second support arm 220 is relatively large, and the connection stability is relatively high.

[0062] Combination Figure 4 As shown, optionally, the first fixed base 100 and the second fixed base 200 are connected by a sliding connector 500. The sliding connector 500 includes a sliding groove 510 and a sliding rod 520, one of which is disposed on the first fixed base 100 and the other on the second fixed base 200. In this way, when the first electric clamp 300 and the second electric clamp 400 clamp the silver-plated grounding piece, the sliding groove 510 and the sliding rod 520 cooperate to provide guidance for adjusting the spacing between the first fixed base 100 and the second fixed base 200, reducing the risk of misalignment.

[0063] Specifically, the first fixed seat 100 is provided with a sliding groove 510, and the second fixed seat 200 is provided with a sliding rod 520.

[0064] Specifically, the first base 110 is provided with a sliding groove 510, and the second base 210 is provided with a sliding rod 520.

[0065] Optionally, one end of the slide rod 520 facing the slide groove 510 is connected to one end of the spring 530, and the other end of the spring 530 is connected to the inner wall of the slide groove 510. In this way, the spring 530 provides elastic force for the slide rod 520 to slide inward into the slide groove 510, so that the gap between the first fixing seat 100 and the second fixing seat 200 is reduced, and the first abutment surface 101 and the second abutment surface 201 are brought closer to each other to clamp the silver-plated grounding piece and reduce the risk of the silver-plated grounding piece falling off.

[0066] Optionally, both ends of the spring 530 are hooked to hooks 540, one hook 540 being fixedly connected to the end of the slide bar 520 facing the slide groove 510, and the other being fixedly connected to the inner wall of the slide groove 510. In this way, the spring 530 can be removed from the hooks 540, facilitating the separation of the slide groove 510 and the slide bar 520, so as to separate the first fixing seat 100 and the second fixing seat 200.

[0067] Optionally, the cross-section of the slide rod 520 is trapezoidal, and the cross-section of the slide groove 510 is trapezoidal. In this way, the risk of the slide rod 520 dislodging from the slide groove 510 when sliding within the slide groove 510 is relatively low.

[0068] Combination Figure 5 As shown, optionally, the first electrical clamp 300 is provided with a first wiring hole 310. This facilitates the insertion of external wires into the first wiring hole 310, reducing the risk of exposed external wires.

[0069] Understandably, the clamp of the first electric clamp 300 is provided with a conductive metal sheet, and the external wire can be electrically connected to the conductive metal sheet by passing through the first wiring hole 310.

[0070] Optionally, the second clamp 400 is provided with a second wiring hole 410. This facilitates the insertion of external wires into the second wiring hole 410, reducing the risk of exposed external wires.

[0071] Understandably, the clamp of the second electric clamp 400 is provided with a conductive metal sheet, and the external wire can be electrically connected to the conductive metal sheet by passing through the second wiring hole 410.

[0072] Specifically, the first electric clamp 300 and the second electric clamp 400 are located on the same horizontal plane.

[0073] Optionally, when the first fixing seat 100 and the second fixing seat 200 abut, there is a gap between the first abutting surface 101 and the second abutting surface 201. This makes it difficult to separate the first abutting surface 101 and the second abutting surface 201 if they are pressed together. The gap between the first abutting surface 101 and the second abutting surface 201 facilitates separation by inserting an auxiliary tool within the gap.
