Description

Technical Field

[0001] The utility model relates to the technical field of electrode testing, in particular to an electrode compatible with testing multiple products. Background Art

[0002] A test electrode refers to a grounding electrode selected for testing potential difference when conducting electrical methods on the ground, in wells, or in tunnels. Generally, a test electrode uses a copper rod, and its length is selected according to needs. Under special conditions, there are also test electrodes made of special substances and with different shapes.

[0003] The contact surface of the existing test electrode is flat, and it can only test terminal-type products and cannot test insulating bowl-type products. The insulating bowl-type products are tested manually, with low test efficiency. Moreover, due to many test items and frequent turnover of products, the appearance is poor.

[0004] In the above solution, the problem of only being able to test terminal-type products is solved by fixing a lead-out needle at the bottom end of the test electrode. When encountering an insulating bowl-type product, the lead-out needle can be probed into the product lead-out end to achieve the test purpose; when encountering a chip-type product, the lead-out needle is probed into the chip, and then the original plane contacts the terminal to achieve the test purpose.

[0005] However, the lead-out needle is fixed at the bottom end of the electrode for a long time, and its surface will be contaminated with a certain amount of dust, affecting the test effect on the product, making the lead-out needle unable to play its normal test role, and requiring manual cleaning regularly. Moreover, during multiple tests, the lead-out needle may tilt, resulting in inaccurate test results and affecting the normal measurement of the product. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose an electrode compatible with testing multiple products, and the technical problem it solves is that the existing test electrode can only test terminal-type products.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme:

[0008] An electrode compatible with testing multiple products includes a test product body, fixing blocks, and electrode rods. There are three electrode rods, and the three electrode rods are evenly arranged in an array at the top end of the test product body. The bottom ends of the electrode rods are fixedly connected with lead-out needles for testing multiple products. There are three fixing blocks, and the three fixing blocks are respectively slidably connected to the outside of the three electrode rods. The bottom end of the electrode rod is fixedly connected with an integrated block. Thus, it can be compatible with testing terminal-type and insulating bowl-type products at the same time, improving the test efficiency. Since it is not manually operated, the unqualified rate of the product appearance will be reduced.

[0009] As a further improvement of the utility model, an elastic structure is fixedly connected between the bottom end of the fixed block and the top end of the bottom surface of the electrode rod, and four pressing blocks are evenly arranged at the bottom end of the electrode rod, so that the electrode rod can be controlled to extend and retract, and the straightening mechanism can be triggered to start.

[0010] As a further improvement of the utility model, the bottom end of the integrated block is fixedly connected to three connecting rods outside the lead-out needle, the middle of the bottom end of the connecting rod is fixedly connected to an internal support block, and the outside of the internal support block is fixedly connected to a wiping structure, so that dust on the surface of the lead-out needle can be simply wiped.

[0011] As a further improvement of the utility model, the inner wall of the internal support block is evenly annularly fixedly connected with four telescopic rods, the side of the telescopic rods away from the inner wall of the internal support block is fixedly connected with a resistance block, and a spring 1 is arranged outside the telescopic rod, and the two ends of the spring 1 are respectively fixedly connected to the side where the resistance block and the internal support block are close to each other. In this way, the resistance block can straighten the lead-out needle under the action of the electrode rod rebounding.

[0012] As a further improvement of the utility model, the top of the abutment block is fixedly connected to a second spring, and the top of the second spring is fixedly connected to an extrusion block, so that the contraction of the abutment block will not be triggered when the electrode rod moves downward.

[0013] As a further improvement of the present invention, a cross opening is provided in the middle of the wiping structure, and the wiping structure is made of sponge material, so that the lead-out needle can pass through the wiping structure and wipe the surface of the lead-out needle.

[0014] As a further improvement of the present invention, the pressing blocks and the extrusion blocks correspond one to one in the horizontal direction, so that each extrusion block will be pressed downward after touching the pressing block.

[0015] As a further improvement of the utility model, the sides of the abutment blocks close to each other are both provided with soft pads, so as to prevent the abutment blocks from causing wear on the surface of the pressing block.

[0016] As a further improvement of the utility model, the extrusion blocks are all fixed on the top surface of the internal support block, so that when the internal support block is located at the bottom end of the pressing block, the abutment block will be fixed.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. Through the fixed block, electrode rod, elastic structure and lead-out needle, when the user presses the electrode rod, the electrode rod drives the rear lead-out needle to move downward, so as to contact the test product body. When the test product body is a terminal insert type product, the lead-out needle will probe into the insert, and then contact the terminal by the original plane to achieve the test purpose. When the test product body is an insulating bowl type product, the lead-out needle probes into the product lead-out end to achieve the test purpose. Thus, it can achieve the compatibility of testing terminal type and insulating bowl type products at the same time. By using a set of testing equipment to be compatible with different types of product testing, it can reduce the repeated purchase and maintenance costs of equipment, thereby improving the testing efficiency. Moreover, the testing equipment can adapt to different types of products, improving the flexibility and adaptability of the production line, and can respond to changes in market demand faster. Unified equipment management and maintenance simplify the operation process and training costs, and reduce the possibility of chaos and errors caused by manual testing. Moreover, through unified testing standards and equipment, it can ensure that products can meet the same quality standards in different types of tests, improving product quality and consistency.

[0019] 2. Through the connecting rod, internal support block and wiping structure, when the electrode rod moves downward under the user's pressing, since the connecting rod fixedly connected to the side of the internal support block is fixed at the bottom end of the integrated block, the wiping structure is relatively in a static state. When the lead-out needle moves downward along the cross opening of the wiping structure, the wiping structure will wipe the surface of the lead-out needle. By wiping the lead-out needle of the test electrode, dirt, oxides or other impurities on the surface can be removed, ensuring the accurate transmission of test signals and improving the accuracy of test results. Moreover, cleaning the lead-out needle of the test electrode helps to reduce the influence of external interference, ensure the reliability of test data, and avoid test errors caused by dirt or impurities. Regularly wiping the lead-out needle can also extend the service life of the electrode, keep the performance of the electrode stable, and avoid electrode damage caused by long-term accumulated dirt. Moreover, keeping the lead-out needle clean can also ensure the consistency between different tests, and avoid data fluctuations or errors caused by different surface states of the test end.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0031] As shown in the figure, an electrode compatible with testing multiple products includes an integrated block 201 , a fixed block 202 , an electrode rod 203 , an elastic structure 204 and a lead-out needle 205 .

[0032] When the user needs to test the test product body 100, align the lead-out end of the test product body 100 with the lead-out pin 205. At this time, the user squeezes the electrode rod 203 downward, so that the lead-out pin 205 tests the test product body 100. When the test product body 100 is a terminal insert type product, the lead-out pin 205 will probe into the insert, and then contact the terminal by the original plane to achieve the test purpose. When the test product body 100 is an insulating bowl type product, the lead-out pin 205 probes into the product lead-out end to achieve the test purpose. Thus, it can be compatible with the tests of both terminal type and insulating bowl type products. By using a set of test equipment to be compatible with the tests of different types of products, the repeated purchase and maintenance costs of the equipment can be reduced, thereby improving the test efficiency.

[0033] During the downward movement of the electrode rod 203, the lead-out pin 205 will pass through the cross opening formed on the surface of the wiping structure 303, so that the wiping structure 303 wipes the lead-out pin 205. Since the elastic structure 204 fixedly connected to the top of the bottom surface of the electrode rod 203 is connected to the fixed block 202, the downward movement of the electrode rod 203 will drive the elastic structure 204 to undergo elastic deformation. After the lead-out pin 205 finishes testing the product, the user releases the electrode rod 203. At this time, the elastic structure 204 will rebound, driving the lead-out pin 205 to move upward. When moving upward, the lead-out pin 205 will be wiped again inside the wiping structure 303. By wiping the lead-out pin 205 of the test electrode, dirt, oxides or other impurities on the surface can be removed, ensuring the accurate transmission of the test signal and improving the accuracy of the test results. Moreover, cleaning the lead-out pin 205 of the test electrode helps to reduce the influence of external interference, ensure the reliability of the test data, and avoid test errors caused by dirt or impurities.

[0034] Furthermore, when the electrode rod 203 moves downward, the pressing block 206 fixedly connected to the bottom end of the electrode rod 203 will move downward at the same time. When the pressing block 206 contacts the extrusion block 308, the extrusion block 308 will be squeezed downward. At this time, the spring 2 307 at the bottom end of the extrusion block 308 will be elastically deformed. The normal state of the spring 1 305 is set to the state of elastic deformation. When the extrusion block 308 completely enters the resistance block 306, the resistance block 306 will be pulled by the rebound force of the spring 1 305. Closely fit together, set the abutment block 306 to completely fit the top diameter of the lead-out needle 205. When the test is completed, the lead-out needle 205 rebounds under the drive of the elastic structure 204, and the basic shape of the lead-out needle 205 is conical, so that the abutment block 306 will slightly correct the position of the lead-out needle 205 when it fits with the lead-out needle 205. Through slight correction, it can ensure that the lead-out needle 205 of the test electrode is more tightly and stably connected to the connector or test fixture, reduce contact resistance, and improve the reliability and stability of signal transmission. Moreover, correction can help eliminate deformation or damage of the lead-out needle 205, especially in the case of frequent movement and plugging, which can extend the service life of the lead-out needle 205 and reduce the risk of damage.

[0035] Furthermore, when the abutment block 306 moves along the lead-out needle 205, the abutment block 306 will squeeze the spring 1 305 to move inside the internal support block 302. When the abutment block 306 moves to the bottom of the lead-out needle 205, the squeeze block 308 will move to the top opening of the internal support block 302 again. At this time, the squeeze block 308 is again fixed to the surface of the internal support block 302 under the rebound of the spring 2 307, so as to ensure that the correction action is triggered at the predetermined time and position, thereby ensuring that the correction operation of the lead-out needle 205 is accurate and correct. Moreover, by controlling the trigger, it can be ensured that the execution mode and strength of each correction action are consistent, avoiding differences caused by human factors.

[0036] The advantages of the utility model are: 1) It can be compatible with the testing of terminal-type and insulating bowl-type products at the same time. By using a set of testing equipment that is compatible with the testing of different types of products at the same time, it can reduce the cost of repeated purchase and maintenance of equipment, thereby improving testing efficiency. 2) It can extend the service life of the electrode, maintain the stability of the performance of the electrode, and avoid damage to the electrode caused by long-term accumulation of dirt. 3) Correction can help eliminate deformation or damage to the lead-out needle 205, especially in the case of frequent movement and plugging and unplugging, which can extend the service life of the lead-out needle and reduce the risk of damage. 4) It can ensure that the correction action is triggered at the predetermined time and position, thereby ensuring that the correction operation of the lead-out needle is accurate and correct.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
