[0022] Please refer to Figure 1 This application discloses an auxiliary device 100 for high-voltage insulation testing of a relay 200, which mainly includes a test plate 1, a mounting base 2, and a contact 3. The mounting base 2 is disposed on the test plate 1 for mounting the relay 200. The mounting base 2 has several test probes (not shown) for connecting to the pins of the relay 200. The test plate 1 has multiple measuring contacts 11, including several first measuring contacts 111 and one second measuring contact 112. These first measuring contacts 111 are at least partially connected to the test probes of the mounting base 2 to achieve high-voltage insulation testing of different pins of the relay 200. The contact 3 is disposed on one side of the mounting base 2 and is a conductive element. One end of the contact 3 is connected to the second measuring contact 112 on the test plate 1, and the other end is used to connect to the housing of the relay 200, thereby testing the high-voltage insulation of the relay 200's housing.

[0023] Understandably, both the first measuring contact 111 and the second measuring contact 112 are essentially measuring contacts 11, differing only in the objects they connect to. The first measuring contact 111 is used to connect to the test probe of the mounting base 2, while the second measuring contact 112 is used to connect to the contact element 3. Figure 1 In order to make it easier to distinguish the first measuring contact 111 and the second measuring contact 112, the appearance of the first measuring contact 111 and the second measuring contact 112 is designed to be different, but in fact their appearance can be the same.

[0024] Before performing high-voltage insulation testing, the relay 200 to be tested is inserted into the mounting base 2, so that each pin of the relay 200 is connected to the corresponding measuring contact 11 through the test probes of the mounting base 2, and the housing of the relay 200 is connected to the contact element 3. During the high-voltage insulation testing process, it is only necessary to connect the corresponding measuring contact 11 with the high-voltage insulation testing equipment to complete each test item of the high-voltage insulation test. The test points for high-voltage insulation testing can include normally open contact test points, normally closed contact test points, coil positive terminal test points, coil negative terminal test points, and housing grounding test points.

[0025] As can be seen, the relay 200 only needs to be inserted into the mounting base 2 of the high-voltage insulation testing auxiliary device 100 to perform high-voltage insulation testing, eliminating the need for manual clamping, flying wires, and other operations, thus improving testing efficiency. Furthermore, the multiple measuring contacts 11 of the high-voltage insulation testing auxiliary device 100 establish stable connections with the casing and pins of the relay 200, respectively. During testing, only the high-voltage insulation testing equipment needs to be brought into contact with the measuring contacts 11, greatly increasing the operating space and providing not only convenient testing but also stable and reliable contact.

[0026] In addition, this high-voltage insulation testing auxiliary device 100 can be used with probe equipment to realize automated or semi-automated testing processes and improve the parallel testing efficiency of multiple relays 200.

[0027] The following examples illustrate the configuration of the high-voltage insulation testing auxiliary device 100 in some embodiments.

[0028] Please continue to refer to this. Figure 1 Test board 1 can be a square PCB board, which can be made of double-sided copper-clad laminate. Of course, the shape of test board 1 can also be other shapes, such as circular shapes, etc., which are not limited here. The test board 1 has sufficient creepage distance and trace spacing to ensure electrical safety and signal integrity during the test process.

[0029] The test board 1 may also be provided with fixing holes (not shown), which, together with fasteners, can securely install the test board 1 on the test platform, thereby improving the structural stability and operational safety during the test process.

[0030] The test probes of mounting base 2 are connected to the corresponding first measurement contact 111 through the traces (i.e. conductive paths, not shown) on test board 1, ensuring electrical isolation and clear path during high voltage testing.

[0031] The measuring contact 11 is a high-voltage resistant planar structure, compatible with various probe-type high-voltage insulation testing equipment. The planar design facilitates connection to the high-voltage insulation testing equipment, improving connection stability and testing efficiency. The measuring contact 11 can be a rectangular gold-plated pad. Of course, the shape of the measuring contact 11 can also be other shapes, such as elliptical or circular, without limitation. The gold plating design improves the corrosion resistance and electrical contact reliability of the measuring contact 11. The measuring contact 11 is of sufficient size to facilitate contact between the probes of the high-voltage insulation testing equipment and the measuring contact 11. For reference, the size of the measuring contact 11 is much larger than the size of the probes and the pins of the relay 200.

[0032] Optionally, in order to better distinguish the connection relationship between each measuring contact 11 and the test probe and contact 3 of the mounting base 2, markings can be added around the different measuring contacts 11.

[0033] Continue to refer to Figure 1 The mounting base 2 can be positioned at the center of the test plate 1, with multiple measuring contacts 11 regularly distributed around the mounting base 2. Understandably, this regular distribution facilitates the high-voltage insulation testing equipment to contact and test each contact individually, improving testing efficiency. In this embodiment, as... Figure 1 As shown, the multiple measuring contacts 11 can be divided into two groups, each group containing several measuring contacts 11; these two groups of measuring contacts 11 are symmetrically distributed on opposite sides of the edge of the test plate 1, and the measuring contacts 11 in each group are evenly spaced along the edge length of the test plate 1. In other embodiments, other regular arrangement methods can also be selected to arrange the multiple measuring contacts 11, such as circumferentially spaced around the mounting base 2.

[0034] Understandably, the regular arrangement of the measuring contacts 11 facilitates compatibility with probe equipment, enabling rapid and efficient insulation performance testing of batch relays 200, significantly improving testing efficiency, and is particularly suitable for automatic testing stations on relay 200 production lines.

[0035] Secondly, the mounting base 2 is detachably mounted on the test board 1. Considering that the number of pins of the relays 200 varies, the pin arrangement of some relays 200 may change. In this case, different types of mounting bases 2 can be quickly replaced to adapt to the pin distribution of different models of relays 200.

[0036] Mounting base 2 can be a plug-in base, which can be configured with good mechanical strength and electrical contact performance to enable quick plugging and unplugging and multiple reuse of relay 200.

[0037] Please refer to the following: Figure 2The top of the mounting base 2 may have multiple sockets 21 for the corresponding insertion of the pins of the relay 200. These test probes are arranged one-to-one in each socket 21. The number of test probes on the mounting base 2 is not necessarily the same as the number of first measuring contacts 111 on the test board 1, but generally, the number of first measuring contacts 111 will be greater than or equal to the number of test probes on the mounting base 2. When the number of test probes on the mounting base 2 is less than the number of first measuring contacts 111 on the test board 1, some of the first measuring contacts 111 on the test board 1 will be left empty, i.e., not connected to the mounting base 2.

[0038] It should be further noted that if the two types of relays 200 have different pin counts, but their pin arrangements are common, they can also be inserted into the same mounting base 2. Secondly, considering that some relays 200 have different pin arrangements, specific mounting bases 2 can be designed specifically for relays 200 with unique pin arrangements.

[0039] On the test board 1, a conductive path (not shown) is provided between each measurement contact 11 and the position of the test board 1 corresponding to the mounting base 2, for conducting the test probe of the first measurement contact 111 to the mounting base 2.

[0040] The upper end of the test probe is used to contact the corresponding pin of the relay 200, while the lower end of the test probe abuts against the corresponding conductive line. Considering that the pin arrangements of some relays 200 may differ, the lower end of the test probe may not be perfectly centered on the conductive line. For test probes with slightly off-center lower ends, contact can still be achieved due to the width of the conductive line. For test probes with excessively off-center lower ends, the lower end can be bent to ensure contact with the conductive line.

[0041] Alternatively, you can refer to Figure 3 Multiple connection pins 22 are provided at the bottom of the mounting base 2. These connection pins 22 are connected one-to-one with each test probe and are used to insert onto the test board 1 to establish a connection between the test probe and the conductive path on the test board 1. The connection pins 22 can be soldered onto the test board 1.

[0042] Please refer back to the reference. Figure 1 The contact 3 can be vertically connected to the test plate 1 and located on one side of the mounting base 2. The contact 3 may include a metal sheet (not shown) and an insulating sleeve (not shown) covering the metal sheet, with both ends of the metal sheet exposed outside the insulating sleeve to support electrical connection.

[0043] like Figure 1As shown, the test board 1 is also provided with conductive contacts 12, which are located around the mounting base 2 and electrically connected to the second measuring contact 112 via conductive lines on the test board 1. The lower end of the contact 3 can be soldered to the third measuring contact 11 to conduct electricity with the second measuring contact 112. The design of conductive contact 12 + second measuring contact 112 ensures that the housing of the relay 200 is tested independently during the test. It should be noted that the contact 3 can also be connected to the test board 1 by other fixing methods, such as by adhesive or snap-fit, and abut against the conductive contact 12.

[0044] Let's look again. Figure 3 A conductive elastic element 4 can be provided at the upper end of the contact 3. This elastic element 4 is configured between the contact 3 and the relay 200 to ensure the reliability of the electrical connection between the contact 3 and the housing of the relay 200. The elastic element 4 can be an arc-shaped piece, with one end connected to the side of the contact 3 facing the mounting base 2, forming an arc-shaped structure protruding towards the mounting base 2. The other end of the elastic element 4 can be suspended or connected to the contact 3, which is not limited here. When the relay 200 is installed in the mounting base 2, the elastic element 4 will contact the housing of the relay 200. Because the housing of the relay 200 compresses the arc-shaped convex surface of the elastic element 4, the elastic element 4 is tightly connected to the housing of the relay 200 (indirect contact). Since the elastic element 4 undergoes elastic deformation under the action of the relay 200, the elastic element 4 returns to its original shape after the relay 200 is removed. In other embodiments, the elastic element 4 can also be a spiral column, a spiral coil, etc.

[0045] The elastic element 4 can be integrated with the contact element 3, or it can be fixed to the contact element 3 by welding, bonding or other connection methods.

[0046] In other embodiments, the contact 3 can be designed as an elongated elastic sheet, with its upper end inclined to one side of the mounting base 2. When the relay 200 is mounted on the mounting base 2, the upper end of the contact 3 will directly contact the housing of the relay 200, and under the action of the relay 200, it will undergo elastic deformation away from the housing of the relay 200, so that the upper end of the contact 3 is pressed tightly against the housing of the relay 200, thus achieving a reliable connection between the contact 3 and the housing of the relay 200.

[0047] Furthermore, this high-voltage insulation testing auxiliary device 100 can be combined with a data acquisition device to realize the data acquisition, processing, and display of the insulation performance test data of the relay 200. This data acquisition device may include a high-voltage power supply feedback module, a voltage feedback module, and a display module.

[0048] In summary, this high-voltage insulation testing auxiliary device 100 combines the testing of the electrical pins of the relay 200 with the detection of its housing insulation performance. It also boasts advantages such as convenient installation, stable contact, strong adaptability, and high safety and reliability, making it widely applicable in the field of relay 200 insulation performance testing. Specifically: This high-voltage insulation testing auxiliary device 100 features a compact and highly modular structure, organically integrating the mounting base 2, contact elements 3, and test board 1. The measuring contacts 11 are arranged in a circular pattern, meeting the operational requirements of both manual and automated testing equipment, thus improving testing convenience. The conductive path of the test board 1 facilitates maintenance, debugging, and expansion.

[0049] The relay 200 is connected to the test board 1 via the mounting base 2, making insertion and removal convenient. This high-voltage insulation testing auxiliary device 100 can be used multiple times, has high testing efficiency, and is particularly suitable for R&D verification and production sampling inspection scenarios of small batches of multiple models of relays 200, reducing material loss and wasted labor time caused by repeated welding or disassembly.

[0050] Contact 3 maintains stable contact with the housing of relay 200, and combined with independent test points, the insulation performance of the housing can be tested separately. Test plate 1 is fixed to the test platform or equipment fixture through mounting holes, further ensuring the stability of the test and the repeatability of the operation.

[0051] This high-voltage insulation testing auxiliary device 100 can achieve compatible testing of various relay 200 structures by changing the mounting base 2 or adjusting the mapping relationship between the measuring contact 11 and the pins of the mounting base 2, depending on the different relay 200 models. This avoids the need to redesign the test board 1 for testing different relays 200, and has high versatility and scalability.

[0052] This high-voltage insulation testing auxiliary device 100 supports high-voltage insulation performance testing of relays 200 between the coil positive and negative poles, normally open and normally closed contacts, and the metal casing. It covers the main insulation paths of the relay 200, comprehensively reflecting its insulation level and effectively screening out products with problems such as breakdown, leakage, and creepage. Each test point has an independent test channel, and all test points are designed with high-voltage withstand capability and standard-distance wiring, effectively preventing misjudgments or breakdowns caused by interference or discharge between test points. No direct soldering is required between the relay 200 and the high-voltage insulation testing equipment, avoiding damage to the relay 200 body and improving the overall safety and reliability of the test.

[0053] In addition, this application also constructs an automatic high-voltage insulation testing system (not shown), which includes a power supply device, a probe device, a test platform and a fixture device, and also includes the aforementioned high-voltage insulation testing auxiliary device 100.

[0054] The high-voltage insulation testing auxiliary device 100 is fixed on the test platform. The power supply device provides the high-voltage power required for the high-voltage insulation test. The clamping device holds the relay 200 to be tested and mounts it onto the mounting base 2. The probe device connects its probes to the measuring contacts 11 on the test board 1 according to a preset program to complete at least one high-voltage insulation test item.

[0055] Understandably, in a high-voltage insulation automatic testing system, automatic high-voltage insulation testing of multiple relays 200 can be achieved. The fixture equipment can install each relay 200 onto the mounting base 2 one by one, and remove the relay 200 from the mounting base 2 after the test is completed. After the relay 200 is installed, the probe equipment can automatically control the gas probe to contact the measuring contact 11 of the test board 1, and apply the high-voltage power supply to perform the high-voltage insulation test. The mainstream high-voltage insulation test items include several, including normally open contact test items, normally closed contact test items, coil positive pole test items, coil negative pole test items, and casing grounding test items.

[0056] It should be noted that the composition of the power supply equipment, probe equipment, test platform, and fixture equipment, as well as how to automate the fixture equipment and probe equipment, can be found in relevant technologies and will not be elaborated here.

[0057] In some embodiments, the high-voltage insulation automatic testing system further includes a data acquisition device for acquiring, processing, and displaying data related to the insulation performance test of the relay 200. This data acquisition device may include a high-voltage power supply feedback module, a voltage feedback module, and a display module.

[0058] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
