Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, and particularly relates to an efficient withstand voltage testing device. Background Technique

[0002] When inductors are produced, voltage tests of the inductors are required. The traditional method is to use a withstand voltage testing device to test a single inductor. In order to achieve efficient testing, there are existing devices for testing multiple inductors simultaneously.

[0003] Publication No. CN215728576U, a multi-channel inductor withstand voltage testing device, which relates to the field of inductor voltage testing devices. It aims to solve the problem that the inductor voltage testing device generally uses only a set of detection heads to detect inductors, reducing the overall detection efficiency. The key points of its technical solution are that it includes a detection table body and a positioning installation table. One side of the upper end of the positioning installation table is fixedly connected with a pushing cylinder. The movable end of the pushing cylinder is fixedly connected with a first installation frame body. Inside the first installation frame body, there are fixedly connected with multiple groups of first detection pole pieces distributed at equal intervals. The side of the upper end of the positioning installation table far from the pushing cylinder is fixedly connected with a second installation frame body. Inside the second installation frame body, there are fixedly connected with second detection pole pieces corresponding to the distribution of the first detection pole pieces. An inductor positioning mechanism for positioning the inductor is movably connected between the first installation frame body and the second installation frame body. It achieves the effects of rapid detection, convenient loading and unloading, and positioning detection.

[0004] This device can test multiple inductors simultaneously, which is more efficient. However, when the inductor is placed in the placement groove opened on the fixing frame body, when placing it, the pins of the inductor need to be aligned with the positioning slots. The pins themselves are slender. In order to accurately position with the detection pole pieces, the smaller the size of the positioning slots is, the more accurate the positioning of the pins is. Therefore, when inserting the pins of the inductor into the positioning slots, the staff needs to align with the positioning slots and needs to concentrate during the operation. Otherwise, if there is a deviation when the pins are inserted and they come into contact with the inner wall of the placement groove, it will cause the pins to bend. Content of the Utility Model

[0005] The purpose of the utility model is to provide an efficient withstand voltage testing device to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An efficient withstand voltage testing device, including a detection device, on one side of the detection device, there is an inductor to be detected. On the front and back of the inductor, there are respectively a second detection pole piece and a first detection pole piece for contacting the pins of the inductor. It further includes:

The top of the installation base is provided with a limiting frame for restricting the rotation of the inductor, and one end of the installation base is provided with a pushing member for restricting the movement of the inductor;

[0010] A moving component, which is used to drive the installation component to move. The moving component is arranged at the bottom end of the installation component.

[0011] Preferably, the bottom end of the limiting frame is fixedly connected to the top end of the installation base. The limiting frame is used to restrict the rotation of the inductor by fitting the outer wall of the inductor. The pins of the inductor are inserted into the pin slot.

[0012] Preferably, the pushing member includes a pressing block. The pressing block is arranged on one side of the top end of the installation base, and the pressing block is used to press the inductor.

[0013] Preferably, the front of the limiting frame is provided with a first circular through slot, and the front of the pressing block is provided with a second circular through slot. A locking rod is inserted into the second circular through slot, and the locking rod is inserted into the first circular through slot. The locking rod is used to lock the position of the pressing block in the limiting frame.

[0014] Preferably, the moving component includes a passive block. The top end of the passive block is fixedly connected with a plug-in block.

[0017] The technical effects and advantages of the present utility model:

[0018] The utility model utilizes the design of an inductor, a pushing member and an installation assembly. By opening a pin slot at the top of the installation base, the size of the pin slot is larger than that of the pin. Therefore, when installing the inductor, there is no need for the staff to align the pins. When installing the inductor, through the fitting restriction of the inner wall of the limiting frame on the outer wall of the inductor, the inductor cannot rotate. As multiple inductors are placed one by one, finally, the extrusion block is used to extrude and fix the multiple inductors, so that the inductors are positioned and will not shake. Thus, the inductors can be detected. In this way, there is no need to deliberately align the pins. At the same time, the size of the pin slot is larger than that of the pin, which can also protect the pins and avoid pin bending during installation. Description of the Drawings

Detailed Implementation Modes

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a highly efficient voltage withstand testing device as Figures 1-7 shown, which includes a detection device 1. On one side of the detection device 1, there is an inductor 6 to be detected. A second detection pole piece 3 and a first detection pole piece 2 for contacting the pins of the inductor 6 are respectively arranged on the front and back of the inductor 6. It further includes:

[0029] A fixing component 4 for installing the first detection pole piece 2;

[0030] A pushing component 5 for installing the second detection pole piece 3;

[0031] An installation component 7 for installing the inductor 6. The installation component 7 includes an installation base 71. On one side of the installation base 71, there is a pin slot for placing. On the front of the installation base 71, there is an insertion slot for the first detection pole piece 2 and the second detection pole piece 3 to be inserted. At the top of the installation base 71, there is a limiting frame 72 for restricting the rotation of the inductor 6. At one end of the installation base 71, there is a pushing member 9 for restricting the movement of the inductor 6;

[0032] A moving component 8 for driving the installation component 7 to move. The moving component 8 is arranged at the bottom of the installation component 7.

[0033] Specifically, the bottom end of the limiting frame 72 is fixedly connected to the top end of the installation base 71. The limiting frame 72 is used to restrict the rotation of the inductor 6 by fitting the outer wall of the inductor 6. The pins of the inductor 6 are inserted and connected with the pin slot. The pushing member 9 includes a pressing block 91. The pressing block 91 is arranged on one side of the top end of the installation base 71. The pressing block 91 is used to press the inductor 6. On the front of the limiting frame 72, there is a first circular through slot. On the front of the pressing block 91, there is a second circular through slot. A locking rod 92 is inserted in the second circular through slot. The locking rod 92 is inserted and connected with the first circular through slot. The locking rod 92 is used to lock the position of the pressing block 91 on the limiting frame 72. The moving component 8 includes a passive block 81. At the top end of the passive block 81, there is a plug-in block 82. A groove is opened at the bottom end of the installation base 71. The plug-in block 82 is inserted and connected with the groove. The plug-in block 82 is used to drive the installation base 71 to move synchronously.

[0034] Further, the inductor 6 is an existing wound inductor, whose outer frame is a rectangular frame. The limiting frame 72 is in a C shape, and the size of the inner wall of the C-shaped notch matches the width of the rectangular frame of the inductor 6. By tightly fitting the inner wall of the limiting frame 72 to the outer wall of the rectangular frame, the installation of the inductor 6 is restricted. The width of the pin slot is less than the width of the rectangular frame of the inductor 6 and is 0.5 times the width of the rectangular frame, which is much larger than the diameter of the pins of the inductor 6, so that the pins can be isolated and protected. The bottom end of the limiting frame 72 is welded and fixed to the top end of the mounting base 71. The number of inductors 6 placed corresponds one-to-one with the number of the first detection electrode plate 2 and the second detection electrode plate 3. The extrusion block 91 is arranged at the C-shaped notch position after placing the maximum number of inductors 6. Two second circular through slots are symmetrically opened at the bottom of the extrusion block 91. Therefore, when installing the extrusion block 91, there is no need to consider the front and back. The sizes of the first circular through slot and the second circular through slot are the same and match the outer diameter of the locking rod 92. When the locking rod 92 is inserted into the inside of the first circular through slot and the second circular through slot at the same time, the extrusion block 91 is fixed at one end of the limiting frame 72, and multiple inductors 6 installed inside the limiting frame 72 are mutually extruded, so that the inductors 6 are fixedly installed inside the limiting frame 72. The bottom end of the plug-in block 82 is welded and fixed to the top end of the passive block 81. Two plug-in blocks 82 are symmetrically arranged and are respectively arranged on both sides of the top end of the passive block 81. Circular grooves for inserting the guide rod 42 are symmetrically opened on the front surface of the passive block 81. The size of the groove matches the size of the plug-in block 82. The number and position of the grooves correspond to the number and position of the plug-in blocks 82 respectively.

[0035] Specifically, the fixing assembly 4 includes a fixing block 41 and a workbench 44. The bottom end of the fixing block 41 is fixedly connected to the top end of the workbench 44. A guide rod 42 for restricting the moving direction of the moving assembly 8 and the pushing assembly 5 is fixedly connected to the front surface of the fixing block 41. A first elastic block 43 for pushing the moving assembly 8 is fixedly connected to the front surface of the fixing block 41. The pushing assembly 5 includes a moving block 51 and a cylinder 52. The output end of the cylinder 52 is fixedly connected to the front surface of the moving block 51. A second elastic block 53 for pushing the moving assembly 8 is fixedly connected to the back surface of the moving block 51.

[0036] Furthermore, the settings of the detection device 1, the first detection pole piece 2, the second detection pole piece 3, the fixing component 4, and the inductor 6 are similar to the working principles of the detection body, the first detection pole piece, the second detection pole piece, the pushing cylinder, the first mounting frame body, the second mounting frame body, the guide column, the buffer pad, etc. of the existing publication number CN215728576U. By respectively installing the first detection pole piece 2 and the second detection pole piece 3 inside the fixed block 41 and the moving block 51, electrically connecting the detection heads of the detection device 1 to the first detection pole piece 2 and the second detection pole piece 3 respectively, and then starting the cylinder 52 to push the moving block 51 to move towards the fixed block 41, the moving block 51 squeezes and pushes the passive block 81 to move synchronously, so that the ends of the first detection pole piece 2 and the second detection pole piece 3 are inserted into the insertion grooves of the mounting seat 71 and contact the pins of the inductor 6, thereby performing the withstand voltage detection of the inductor 6. Circular grooves are formed on the fronts of the moving block 51 and the passive block 81. Under the restriction of the guide rod 42, the moving block 51 and the passive block 81 can only move linearly.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
