Description

Technical Field

[0001] The utility model relates to a detection device for electronic components, and particularly to a withstand voltage detection device for a network filter. Background Art

[0002] The existing withstand voltage detection of network filters is mainly divided into automated detection and manual detection. Considering cost issues, many small electronic component factories mainly use manual detection, such as using a brush for detection. The withstand voltage detection mainly conducts power-on detection on the network filter through direct current. If a "beep" sound is generated and accompanied by electric sparks, it indicates that there are problems such as high withstand voltage or high inductance in the network filter, and repair or scrapping is required.

[0003] When the brush tool is in operation, it can detect 8 network filters at a time. However, after long-term use of the brush tool, the copper wires at the front end of the brush tool are severely worn, resulting in uneven copper wires. There is a situation where the copper wires at the front end of the brush do not contact the pin feet at the bottom of the network filter sufficiently, resulting in a certain error in the detection accuracy. Therefore, in actual operation, when facing a large number of network filters to be detected, the copper wires need to be frequently replaced, which not only increases the production cost but also affects the detection efficiency. Summary of the Utility Model

[0004] Aiming at the technical problem that the brush tool used in the existing detection has severe wear after long-term use, the utility model provides a withstand voltage detection device for a network filter, which has the advantages of anti-wear and durability.

[0038] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0039] Embodiment:

[0040] See Figure 1 , this embodiment discloses a withstand voltage detection device for a network filter, including an insulating bottom plate 10, metal sheets 20, and a withstand voltage tester (not shown in the figure). Specifically, the insulating bottom plate 10 is of a square structure. Generally speaking, the insulating bottom plate 10 is made of non-metallic materials, such as it can be made of plastic, or it can be made of wood, etc.

[0041] There are several metal sheets 20. All the metal sheets 20 are laid on one side surface of the insulating bottom plate 10. At the same time, the length directions of all the metal sheets 20 are parallel to each other, and the two ends of all the metal sheets 20 are aligned with each other, so that all the metal sheets 20 are neatly arranged on the insulating bottom plate 10. In addition, there are equal-spacing gaps between any two adjacent metal sheets 20.

[0042] All the aforesaid metal sheets 20 further include several first metal sheets 21 and several second metal sheets 22. The number of the first metal sheets 21 is equal to the number of the second metal sheets 22, and all the first metal sheets 21 and all the second metal sheets 22 are distributed on the insulating bottom plate 10 in a one-by-one interval manner.

[0043] The withstand voltage tester has two electrode wires 30 for outputting voltage. One of the electrode wires 30 is electrically connected to all the first metal sheets 21, so that all the first metal sheets 21 are connected in parallel to this electrode wire 30. The other electrode wire 30 is electrically connected to all the second metal sheets 22, so that all the second metal sheets 22 are connected in parallel to this electrode wire 30.

[0044] In this embodiment, first, the insulating bottom plate 10 is set to avoid causing harm to the detector. Multiple metal sheets 20 are set on the insulating bottom plate 10, and the adjacent metal sheets 20 are electrically connected to two different electrode wires 30 of the withstand voltage tester.

[0045] During use, place the side of the network filter 40 with pin feet on the insulating base plate 10, and make the pin feet on both sides of the network filter 40 contact the adjacent first metal sheet 21 and second metal sheet 22 respectively. Repeat this process to place several network filters 40 on all the metal sheets 20, so that all the network filters 40 form a parallel structure on all the metal sheets 20. At the same time, multiple network filters 40 can be placed on the same metal sheet 20, so that the network filters 40 on the same metal sheet 20 form a series structure. Then turn on the withstand voltage tester for detection.

[0046] In this technical solution, the traditional copper wire brush is replaced with a more durable metal sheet 20. The metal sheet 20 only contacts the pin feet of the network filter, and there is no relative movement between the two, so there is no mutual dynamic friction between the two, which can greatly improve the durability of the metal sheet 20, and thus solve all the technical problems in the background technology.

[0047] In one specific embodiment:

[0048] As Figure 1 and Figure 2 shown, the detection device further includes a sleeve 51. The structure of the sleeve 51 is long and strip-shaped, and the cross-section of the sleeve 51 is square. A long strip-shaped magnetic strip 52 is provided on the sleeve 51, and the length direction of the magnetic strip 52 is the same as the length direction of the sleeve 51.

[0049] In this embodiment, several network filters 40 can be adsorbed on the sleeve 51 through the magnetic strip 52. By adjusting the position and placement direction of the network filters 40, and then pressing the sleeve 51 on all the metal sheets 20, several network filters 40 can be placed on all the metal sheets 20 at one time.

[0050] In this embodiment, on the one hand, the network filters 40 can be quickly placed on all the metal sheets 20 through the sleeve 51, and on the other hand, the sleeve 51 can be pressed on all the network filters 40 to prevent the network filters 40 from shifting during the detection process.

[0051] In another specific embodiment:

[0052] The length of the metal sheet 20 is at least more than twice the length of the network filter 40, so that multiple network filters 40 can be placed on a single metal sheet 20. Therefore, several network filters 40 can be placed on all the metal sheets 20 through multiple sleeves 51 to achieve the purpose of improving the detection effect.

[0053] In another specific embodiment:

[0054] On both sides of one surface of the sleeve 51, there is respectively an inward concave structure, such that the cross-section of the sleeve 51 is in a convex shape. Inside each of the two inward concave structures, there is a magnetic strip 52 arranged. By providing the inward concave structures on both sides of the sleeve 51, the cross-section formed by the sleeve 51 and the magnetic strip 52 is still a rectangular structure, which is beneficial to stably place the network filter 40 on the sleeve 51.

[0055] In another specific embodiment:

[0056] The insulating base plate 10 has a raised support portion 11. The support portion 11 is arranged around the periphery of all the metal sheets 20, and the support portion 11 is equal to the height of the network filter 40.

[0057] In this embodiment, by providing the raised support portion 11 on the insulating base plate 10, the two ends of the sleeve 51 can be propped up by the support portion 11, avoiding the network filter 40 from being pressed and the pin feet thereof from being bent.

[0058] In another specific embodiment:

[0059] The insulating base plate 10 is further provided with a third metal sheet 23 and a fourth metal sheet 24. The third metal sheet 23 and the fourth metal sheet 24 are arranged in parallel with each other, and there is a gap between the two. The third metal sheet 23 is connected to an electrode wire 30, and the fourth metal sheet 24 is connected to another electrode wire 30.

[0060] Wherein, the length of the third metal sheet 23 is equal to the length of the fourth metal sheet 24, and is greater than the length of the network filter 40.

[0061] In this embodiment, by providing the third metal sheet 23 and the fourth metal sheet 24, it is convenient to perform a separate confirmation detection when there is a problem with the network filter 40.

[0062] The above-described embodiments only represent the specific implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
