Therefore, to facilitate staff testing of the conductive rubber strip, it is necessary to provide a conductive rubber strip testing clamp. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] The present application embodiment discloses a conductive rubber strip detection clamp, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a mounting base 1, on which a test circuit board 2 is mounted. A test station 21 for accommodating a conductive rubber strip is provided on the test circuit board 2, and a plurality of conductive contacts 22 for electrically connecting to the conductive rubber strip are evenly spaced along the length direction of the conductive rubber strip on the test circuit board 2. A clamping assembly 3 for clamping the conductive rubber strip is mounted on the mounting base 1. A measuring device 4 for measuring the resistance value between each conductive contact 22 on the conductive rubber strip and an electrode connector is mounted on the mounting base 1, and an electrode connector for contacting the end of the conductive rubber strip is provided on one detection end of the measuring device 4 (the electrode connector is located at the bottom of the first clamping plate 31, not shown in the figure), and a measuring pen 41 is provided on the other detection end of the measuring device 4, and the measuring pen 41 is used to contact each conductive contact 22.

[0019] In the embodiment of the present application, the measuring device 4 is a resistance tester. After the staff member places the conductive rubber strip on the test station 21, the clamping assembly 3 securely mounts the conductive rubber strip on the test circuit board 2. The electrode connector is then brought into contact with one end of the conductive rubber strip. The measuring pen 41 sequentially contacts each conductive contact 22 to obtain the resistance value between each conductive contact 22 and the electrode connector on the conductive rubber strip. The multiple conductive contacts 22 on the test circuit board 2 evenly divide the conductive rubber strip into multiple segments. In this way, the uniformity and consistency of the resistance value of the conductive rubber strip can be tested, which improves the convenience of testing the conductive rubber strip.

[0020] In the embodiment of the present application, other circuits and electronic components on the test circuit board 2 are not shown in the figure, and sufficient margins must be left for the wires on the measuring device 4 used to connect to the measuring pen 41 and the electrode connector.

[0021] Specifically, the clamping assembly 3 includes a first clamping plate 31 for pressing down against the conductive rubber strip. The first clamping plate 31 is vertically slidably mounted on the mounting base 1 and is located above the testing station 21. The electrode connector is mounted on the first clamping plate 31 at a position where it contacts the end of the conductive rubber strip. A driving member 5 is mounted on the mounting base 1 to drive the first clamping plate 31.

[0022] In the embodiment of the present application, the driving member 5 can drive the first clamping plate 31 to move downward to abut the conductive rubber strip, so that the electrode connector contacts the end of the conductive rubber strip. Then, the tip of the measuring pen 41 contacts the conductive contact piece 22, and the resistance value between the conductive contact piece 22 on the conductive rubber strip and the electrode connector can be measured.

[0023] Specifically, the driving member 5 includes a first mounting frame 51 and an electric push rod 52. The first mounting frame 51 is bolted to the mounting base 1. The electric push rod 52 is mounted on the first mounting frame 51, and the movable end of the electric push rod 52 is vertically downward and connected to the first clamping plate 31.

[0024] Furthermore, a second mounting bracket 6 is bolted to the mounting seat 1 , and a mounting plate 7 is slidably provided on the second mounting bracket 6 along the length direction of the conductive rubber strip. The mounting plate 7 is located above the conductive contact piece 22 , and the measuring pen 41 is vertically movably provided on the mounting plate 7 .

[0025] In this embodiment of the present application, the second mounting bracket 6 is provided with a sliding groove for the movement of the mounting plate 7. A mounting hole with an inner diameter matching that of the measuring pen 41 is vertically penetrated through the mounting plate 7. The measuring pen 41 is vertically and movably inserted into the mounting hole. By moving the mounting plate 7, the measuring pen 41 can pass over each conductive contact 22 in sequence, bringing the pen tip into contact with the conductive contact 22. During the inspection process, the measuring pen 41 contacts the conductive contact 22 solely under its own weight. This ensures that the pressure from the measuring pen 41 is consistent across each conductive contact 22, and also ensures that the distance from the contact point of the measuring pen 41 on the conductive contact 22 to the conductive rubber strip is consistent.

[0026] Furthermore, a positioning plate 8 for contacting the end of the conductive rubber strip is bolted to one end of the test circuit board 2 on the mounting base 1. Two second clamping plates 9 for jointly clamping the two sides of the conductive rubber strip are slidingly provided on the positioning plate 8 along the width direction of the conductive rubber strip. A limiting member 10 is installed on the positioning plate 8 for limiting the movement of the second clamping plate 9 relative to the positioning plate 8.

[0027] In the embodiment of the present application, the two second clamping plates 9 can clamp both sides of the conductive rubber strip together to prevent the conductive rubber strip from tilting relative to the conductive contact piece 22, thereby further improving the accuracy of the test result.

[0028] Specifically, the limiting member 10 includes multiple limiting bolts, and the second clamping plate 9 is provided with multiple strip holes 91 along its own moving direction. The strip holes 91 on the positioning plate 8 are provided with threaded holes with sizes matching the limiting bolts. The multiple limiting bolts pass through the corresponding strip holes 91 one by one and are threadedly connected in the threaded holes.

[0029] In the embodiment of the present application, the staff can adjust the distance between the two second clamping plates 9 according to the width of the conductive rubber strip, and then limit the movement of the second clamping plates 9 relative to the positioning plate 8 by the limiting bolts.

[0030] The operating principle of the conductive rubber strip detection clamp of the present embodiment is as follows: After the staff member places the conductive rubber strip on the test station 21, the conductive rubber strip is securely mounted on the test circuit board 2 using the clamping assembly 3. The electrode connector is then brought into contact with one end of the conductive rubber strip. The measuring pen 41 sequentially contacts each conductive contact 22 to obtain the resistance value between each conductive contact 22 on the conductive rubber strip and the electrode connector. Because the multiple conductive contacts 22 on the test circuit board 2 evenly divide the conductive rubber strip into multiple segments, this method can be used to test the uniformity and consistency of the resistance value of the conductive rubber strip, thereby improving the convenience of testing the conductive rubber strip.

Therefore, the appended claims are intended to be interpreted as encompassing the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
