Description

Technical Field

[0001] The utility model relates to a withstand voltage detection tool for network filters, and particularly to a tool for efficiently testing the withstand voltage of semi-finished network filters. Background Art

[0002] The current method for testing the withstand voltage of semi-finished network filters is to conduct a single-piece power-on test for each semi-finished product. The withstand voltage test is mainly used to test the withstand voltage and inductance of network filters. If the withstand voltage is high or the inductance is high, it indicates that there is damage to the internal circuit of the network filter, and repair or scrapping is required.

[0003] Regarding the current equipment for testing the withstand voltage of semi-finished network filters, large factories will design or purchase corresponding testing equipment specifically, while for small factories, manual detection is mainly used. As a result, there is a phenomenon of low detection efficiency, which is not conducive to large-scale production. At the same time, since the positive and negative copper sheets for power-on in the withstand voltage test are slightly longer than a single network filter, if the operator touches them and the power is not cut off in time, the 36V DC power will come into contact with the human body, posing a certain potential safety hazard. Summary of the Utility Model

[0004] Aiming at the technical problems of low efficiency and potential safety hazards in detecting semi-finished network filters in the prior art, the utility model provides a tool for efficiently testing the withstand voltage of semi-finished network filters, which has the advantages of safety and high detection efficiency.

[0018] Optionally, the brush is in a cylindrical structure, and all the metal wires on the brush are distributed within a cylindrical structure.

[0019] Optionally, it further includes an accessory rack;

[0020] When the tool is not in use, the handle can be placed on the accessory rack.

[0035] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0036] Embodiment:

[0037] See Figure 1, this embodiment discloses a tool for efficiently testing the withstand voltage of semi-finished network filters, including a wire 10, a handle 20, a brush 30, and a withstand voltage tester (not shown in the figure). Specifically, there are two wires 10 (or two strands), and one end of each of the two wires 10 is connected to a plug 40. Insulating materials are wrapped around the outside of the two wires 10. The two wires 10 can be twisted together in a twisted shape or wrapped together by an external plastic wire casing.

[0038] The handle 20 is a long strip structure and is made of insulating materials such as plastic and wood. Among them, there is a channel inside the handle 20, and the channel runs through both ends of the handle 20. The ends of the two wires 10 far from the plug 40 penetrate into the channel from one end of the handle 20.

[0039] Two brushes 30 are provided at the other end of the handle 20, and the two brushes 30 are electrically connected to the two wires 10 respectively. Among them, the brush 30 includes a connecting body 31 and a number of metal wires 32. One end of the connecting body 31 is connected to the end of the handle 20, and a number of metal wires 32 are provided at the other end of the connecting body 31, and the length directions of all the metal wires 32 are the same as the length direction of the connecting body 31.

[0040] Among them, the brush 30 is in a cylindrical structure, and all the metal wires 32 on the brush 30 are distributed within a cylindrical structure. There is a gap between the two brushes 30, and the distance between the center lines of the two brushes 30 is approximately equal to the pin pitch on both sides of the network filter.

[0041] The connecting body 31 is electrically connected to the wire 10, and the connecting body 31 is made of metal material.

[0042] In this embodiment, the wire 10 is a copper core wire, and the connecting body 31 and the metal wires 32 are both made of copper.

[0043] During the use process, the operator holds the handle 20 and uses the two brushes 30 at the end of the handle 20 to contact the pins on both sides of the network filter, so as to detect the network filter through the withstand voltage tester.

[0044] This technical solution can greatly improve the detection speed. At the same time, the handle 20 is made of insulating material, which can improve the safety performance.

[0045] In one specific embodiment:

[0046] One end of the handle 20 is provided with two connection holes (not shown in the figure), and a tubular metal part (not shown in the figure) is arranged in the two connection holes. The metal part is electrically connected to the wire 10. One end of the two connectors 31 is detachably inserted into the two connection holes, and a limiting part (not shown in the figure) for increasing the friction between the hole wall and the outer wall of the connector 31 is arranged in the connection holes.

[0047] In this embodiment, during the use of the brush 30, the metal wire 32 at the front end of the brush 30 needs to be in contact with the pin feet of different network filters for a long time and slide on the pin feet, resulting in a relatively fast wear rate of the metal wire 32. Therefore, by inserting the connector into the connection hole, the brush 30 can be quickly and conveniently replaced after the metal wire 32 at the front end of the brush 30 is severely worn.

[0048] In a preferred embodiment, a metal elastic part (not shown in the figure) is arranged in each of the two connection holes. One end of the metal elastic part abuts against the connector 31, so that when the operator conducts a test, the handle 20 is held in an inclined direction, and the two brushes 30 are at different lengths, improving the comfort during the test. Preferably, the metal elastic part is a spring.

[0049] In another specific embodiment:

[0050] The above-mentioned wire 10 is a copper core wire, so the wire 10 is flexible, can be freely bent, and the handle 20 at the end of the wire 10 can be moved to any position according to requirements. Through this setting, it is convenient to use the brush 30 to detect the network filter.

[0051] Preferably, the wire 10 can also be set as a spiral spring wire structure. In this way, it is possible to avoid the longer wire 10 affecting the production and detection environment.

[0052] Generally speaking, the wire 10 is sleeved inside a pipeline, and the shape of the pipeline can be changed. Through this pipeline, the wire 10 can be fixed into a preset shape, such as the aforementioned spiral shape.

[0053] In another specific embodiment:

[0054] The cross-section of the handle 20 is oval, and the two brushes 30 are respectively close to both ends of the long axis of the oval structure. By setting the cross-section of the handle 20 as an oval structure, it is convenient for the operator to quickly locate the positions of the two brushes 30 when picking up the tool, and the oval end face can provide sufficient space for the installation of the two brushes 30 to ensure that the required gap is formed between the two brushes 30.

[0055] In another specific embodiment:

[0056] The tool further includes an accessory rack (not shown in the figure). The accessory rack is placed on the operating table during detection, and the operator can place the handle 20 on the accessory rack during the break to avoid the phenomenon that the operator's hand accidentally touches the brush 30.

[0057] The above-described embodiments merely represent the specific implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on 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 variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
