Description

Technical Field

[0001] This application relates to the technical field of test fixtures, and in particular to a load aging test fixture. Background Technology

[0002] Load aging tests on sockets are of paramount importance in the field of electrical safety. These tests simulate the working conditions of sockets during long-term use, and this experimental method can comprehensively evaluate the performance of sockets under continuous load. This is of great significance for improving the quality of sockets and ensuring electrical safety.

[0003] In traditional socket load aging tests, a testing fixture consisting of a testing machine and lamp holders is typically used to complete the test. The lamp holder, connected to a plug and a light bulb, is then plugged into the socket inside the testing machine. When it's necessary to improve the socket's testing efficiency, i.e., increase its load-bearing capacity, multiple lamp holders connected by wires are often used, as commercially available lamp holders are generally for single use. However, with the increasing number of wires, tangling easily occurs during the use of multiple lamp holders connected by wires. Once tangled, it negatively impacts the efficiency of subsequent wire reassembly. Utility Model Content

[0004] The purpose of this application is to provide a load aging test fixture to prevent wires from getting tangled.

[0005] The load aging test fixture provided in this application adopts the following technical solution: it includes a test board and a test machine. The test board is provided with a plug, several lamp holders, several wires and several terminal clamps. Each lamp holder is connected to a light bulb. Adjacent lamp holders are connected in series or in parallel through the wires and terminal clamps. The plug is connected to the lamp holder.

[0006] By adopting the above technical solution, operators can connect adjacent lamp holders in series or parallel according to actual needs, increasing the total power and thus improving the load-bearing capacity of the socket. Each wire is connected by a connector clamp, ensuring that the wires are arranged along a specific route, thereby preventing tangling and facilitating subsequent reassembly.

[0007] Optionally, the test board is provided with a support foot on the side away from the lamp holder, all the wiring clips are located on the side of the test board away from the lamp holder, and the wires pass through the test board.

[0008] By adopting the above technical solution, the support feet can support the test board, allowing the side of the test board away from the lamp holder to be suspended, providing space for the installation of wires and connectors. The wire portion and connectors are located on the side of the test board away from the lamp holder. When the support feet contact the tabletop, the test board covers the wire portion and connectors, keeping the side of the test board away from the support feet clean and uncluttered.

[0009] Optionally, the test board includes an insulating board and a high-temperature resistant board connected to the insulating board, the lamp holder is connected to the high-temperature resistant board, and the wiring clamp is connected to the insulating board.

[0010] By adopting the above technical solutions, the insulation board can ensure electrical safety, and the high-temperature resistant board can withstand the heat generated by the bulb, thus preventing damage to the test board.

[0011] Optionally, the high-temperature resistant plate is fitted with a transparent cover for covering all the lamp holders.

[0012] By adopting the above technical solution, covering the lamp holder with a transparent cover can protect the lamp holder and the bulb, reduce dust accumulation on the lamp holder and the bulb, and facilitate observation of the bulb's working status.

[0013] Optionally, the connector includes a mounting plate connected to the test board and at least two spring contacts spaced apart on the mounting plate. A mounting groove is formed between two adjacent spring contacts, and the mounting groove is used to mate with the wire. The opening of the mounting groove is narrowed.

[0014] By adopting the above technical solution, during wire installation, the wire moves towards the mounting groove, passing between two adjacent spring clips. The spring clips are compressed, causing elastic deformation and maintaining a tendency to elastically return to their original position. The two spring clips move in opposite directions, increasing the opening size of the mounting groove. Until the wire is fully inserted into the mounting groove, the two spring clips elastically return to their original position and move in opposite directions, returning the opening of the mounting groove to its original size. This prevents the wire from detaching from the mounting groove without external force. The inner wall of the mounting groove also restricts the wire's path, preventing tangling.

[0015] Optionally, the mounting plate is hinged to a limiting plate, and the mounting plate is connected to a fixing component for fixing the limiting plate, the limiting plate for covering the opening of the mounting groove.

[0016] By adopting the above technical solution, after the wire is inserted into the mounting groove, the limiting plate is rotated, and the limiting plate covers the opening of the mounting groove. The limiting plate is fixed to the mounting plate by a fixing component. The limiting plate is designed to prevent the wire from detaching from the mounting groove through the opening.

[0017] Optionally, each of the spring pieces is provided with a guide groove at one end away from the mounting plate. The guide groove communicates with the mounting groove and is used to rotate with the limiting plate.

[0018] By adopting the above technical solution, when the limiting plate rotates, the cooperation between the limiting plate and the guide groove plays a guiding and limiting role in the rotation of the limiting plate, thereby improving the stability of the rotation of the limiting plate and enabling the limiting plate to rotate accurately to the corresponding position.

[0019] Optionally, the limiting plate is provided with abutting parts that correspond one-to-one with the mounting grooves, and the abutting parts are used to abut against the wires.

[0020] By adopting the above technical solution, when the limiting plate rotates to the corresponding position and is fixed on the mounting plate by the fixing component, the clamping part abuts against the wire, and the wire is clamped by the clamping part and the inner wall of the mounting groove, thereby improving the stability of the wire installed on the connector.

[0021] Optionally, the fixing component includes an elastic element, a fixing block disposed on the limiting plate, and a snap-fit ​​block slidably connected to the mounting plate. The snap-fit ​​block is connected to the mounting plate through the elastic element. The snap-fit ​​block is provided with a snap-fit ​​portion, and the fixing block is provided with a snap-fit ​​groove. The snap-fit ​​groove is used to snap-fit ​​with the snap-fit ​​portion, and the snap-fit ​​portion is provided with a guide surface for abutting against the fixing block.

[0022] By adopting the above technical solution, when the limiting plate is rotated, the fixing block rotates along with the limiting plate. During the rotation, the fixing block abuts against the guide surface and drives the locking block to slide towards the elastic element. The elastic element is compressed and generates an elastic shape, maintaining a tendency to elastically return to its original position until the locking part aligns with the locking groove. The elastic element then elastically returns to its original position, forcing the locking block to return to its original position, causing the locking part to engage in the locking groove. The inner wall of the locking groove restricts the rotation of the fixing block, thereby fixing the limiting plate to the mounting plate. When the limiting plate needs to be rotated, the operator presses the locking block towards the elastic element. The elastic element is compressed and generates an elastic shape, maintaining a tendency to elastically return to its original position. The locking part disengages from the locking groove, allowing the limiting plate to rotate. The operator releases the locking block, and the elastic element forces the locking block to return to its original position, allowing the locking part and locking groove to engage again.

[0023] Optionally, the mounting plate is provided with a sliding groove for sliding engagement with the snap-fit ​​block. The inner wall of the sliding groove is provided with a limit rod. The snap-fit ​​block is provided with an oblong hole for sliding engagement with the limit rod. The extension direction of the oblong hole is the same as the sliding direction of the snap-fit ​​block.

[0024] By adopting the above technical solution, when the locking block slides, the sliding cooperation between the limiting post and the waist-shaped hole plays a guiding and limiting role in the sliding of the locking block, thereby improving the stability of the locking block's sliding and preventing the locking block from detaching from the slide groove during the sliding process.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Operators can connect adjacent lamp holders in series or parallel according to actual needs to increase the total power and thus improve the load-bearing capacity of the socket. Each wire is connected by a connector clamp, ensuring that the wires are arranged along a specific route to avoid tangling and facilitate subsequent reassembly.

[0026] 2. The support feet provide support for the test board, allowing the side of the test board away from the lamp holder to be suspended, providing space for the installation of wires and connectors. The wire portion and connectors are located on the side of the test board away from the lamp holder. When the support feet are in contact with the tabletop, the test board covers the wire portion and connectors, keeping the side of the test board away from the support feet clean and tidy.

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0035] This application discloses a load aging test fixture.

[0036] Combination Figure 1 and Figure 2 As shown, the test includes a test board 1 and a testing machine 2. The testing machine 2 is equipped with a socket that is connected to an external power supply. The test board 1 includes an insulating board 11 and a high-temperature resistant board 12 fixedly connected to the insulating board 11. The insulating board 11 is a solid wood insulating board, and the high-temperature resistant board 12 is a high-temperature resistant heat dissipation board. The insulating board 11 is located below the high-temperature resistant board 12. Several lamp holders 13 are fixedly connected to the side of the high-temperature resistant board 12 away from the insulating board 11. Each lamp holder 13 is fixedly connected to a light bulb 14. A transparent cover 3 is installed on the side of the high-temperature resistant board 12 away from the insulating board 11. The transparent cover 3 covers all the lamp holders 13 and the light bulbs 14. The transparent cover 3 can reduce dust falling on the light bulbs 14 and lamp holders 13, and can also allow the condition of the light bulbs 14 to be seen through the transparent cover 3.

[0037] Combination Figure 1 and Figure 2 As shown, each lamp holder 13 is fixedly connected to a wire 15. The end of the wire 15 away from the lamp holder 13 passes through the high-temperature resistant plate 12 and the insulating plate 11 and is located below the insulating plate 11. Depending on the actual needs, two adjacent lamp holders 13 can be connected in series or in parallel through the wire 15. A plug 16 is fixedly connected to the insulating plate 11, and the plug 16 is also connected to the lamp holder 13 through the wire 15. Four support feet 17 are fixedly connected to the side of the insulating plate 11 away from the high-temperature resistant plate 12, and the four support feet 17 are located at the four corners of the insulating plate 11.

[0038] Combination Figure 3 and Figure 4 As shown, a number of wiring clips 4 are connected to the side of the insulating plate 11 away from the high-temperature resistant plate 12. The number of wiring clips 4 is selected according to actual needs. The wire 15 cooperates with the wiring clips 4 to connect the two lamp holders 13. The wiring clip 4 includes a mounting plate 41 and at least two spring pieces 42 spaced apart on the mounting plate 41. The mounting plate 41 is connected to the insulating plate 11 by screws. Taking this embodiment as an example, there are four spring pieces 42. Every two spring pieces 42 form a group. A mounting groove 43 is formed between the two spring pieces 42 in each group. The wire 15 is inserted into the mounting groove 43. The opening of the mounting groove 43 is narrowed. Each spring piece 42 has an arc-shaped surface 421 at the end away from the mounting plate 41. The two arc-shaped surfaces 421 in each group gradually decrease in size towards the mounting groove 43.

[0039] Combination Figure 4 and Figure 5As shown, the mounting plate 41 is hinged to the limiting plate 44. A guide groove 422 is provided at the end of the spring piece 42 away from the mounting plate 41, communicating with the mounting groove 43. The limiting plate 44 rotatably engages with the guide groove 422. Two abutting parts (not shown in the attached diagram) are provided opposite each other on one side of the limiting plate 44. The abutting parts are integrally formed with the limiting plate 44, and each abutting part corresponds to a mounting groove 43. The mounting plate 41 is connected to a fixing component 5. When the limiting plate 44 is fixed by the fixing component 5, the abutting parts abut against the wire 15. The abutting parts are located between the two spring pieces 42, and the wire 15 is clamped by the inner wall of the mounting groove 43 and the abutting parts, thereby improving the stability of the wire 15 mounted on the connector 4.

[0040] Combination Figure 4 , Figure 5 and Figure 6 As shown, the fixing component 5 includes an elastic element 51, a fixing block 52 disposed on the limiting plate 44, and a snap-fit ​​block 53 slidably connected to the mounting plate 41. The fixing block 52 is integrally formed with the limiting plate 44. The mounting plate 41 has a sliding groove 411, in which the snap-fit ​​block 53 slides. The elastic element 51 is a spring, with one end fixedly connected to the snap-fit ​​block 53 and the other end fixedly connected to the inner wall of the sliding groove 411. When the elastic element 51 is not compressed, the end of the snap-fit ​​block 53 away from the elastic element 51 protrudes from the sliding groove 411. The inner wall of the sliding groove 411 is provided with a limiting rod 412, and the snap-fit ​​block 53 has an oblong hole 531. The limiting rod 412 slides and engages with the oblong hole 531, and the extending direction of the oblong hole 531 is the same as the moving direction of the snap-fit ​​block 53. A groove 532 is provided on one side of the snap-fit ​​block 53, and a snap-fit ​​part 533 is provided on the inner wall of the groove 532. The snap-fit ​​part 533 is integrally formed with the snap-fit ​​block 53 and is located between the elastic member 51 and the waist-shaped hole 531. A guide surface 534 is provided at the end of the snap-fit ​​part 533 away from the waist-shaped hole 531. The guide surface 534 is located on the side of the snap-fit ​​part 533 near the limiting plate 44. A snap-fit ​​groove 521 is provided on the fixing block 52, and the snap-fit ​​block 53 engages with the snap-fit ​​groove 521. A clearance groove 413 communicating with the slide groove 411 is provided on the mounting plate 41. During rotation, the fixing block 52 passes through the clearance groove 413 and is positioned in the slide groove 411.

[0041] The implementation principle of a load aging test fixture in this application embodiment is as follows: When installing wire 15, wire 15 is inserted into mounting groove 43. Rotating limit plate 44 causes fixing block 52 to rotate with limit plate 44. During rotation, fixing block 52 abuts against guide surface 534 and drives snap-fit ​​block 53 to slide closer to elastic member 51. Elastic member 51 is compressed and generates elastic shape and maintains the tendency of elastic reset until snap-fit ​​part 533 corresponds to snap-fit ​​groove 521. Elastic member 51 elastically resets and forces snap-fit ​​block 53 to reset, so that snap-fit ​​part 533 is inserted into snap-fit ​​groove 521. The inner wall of snap-fit ​​groove 521 restricts the rotation of fixing block 52, thereby fixing limit plate 44 on mounting plate 41. When it is necessary to remove the wire 15, the worker presses the locking block 53 towards the elastic member 51. The elastic member 51 is pressed and generates an elastic shape and maintains the tendency to elastically return to its original position. The locking part 533 disengages from the locking groove 521, and the limiting plate 44 can rotate. The limiting plate 44 no longer restricts the movement of the wire 15 in the mounting groove 43.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
