Description

Technical Field

[0001] The present application relates to the technical field of electronic component detection equipment, and in particular to a detection device for a switch discharge tube. Background Art

[0002] The switch discharge tube is a switching device that is turned on by voltage. It can provide short-term, high-peak leading-edge voltage and current pulses, and generate high-voltage pulses, which can be used as the ignition switch of xenon lamps. Since switch discharge tubes are widely used in the automotive industry, the breakdown voltage, service life and failure rate of million pieces of switch discharge tubes are subject to stringent requirements.

[0003] Currently, the common switch discharge tube detection device includes a test board and a number of equidistantly distributed contacts. A number of equidistantly distributed test holes are arranged on the test board. The test holes are used to place the switch discharge tubes, and the contacts are used to detect the switch discharge tubes. One of the contact pieces is aligned with a column of equidistantly distributed switch discharge tubes. The number of contact pieces on the current test device is a fixed value, that is, when there are three contact pieces, a test board with three columns of equidistantly distributed test holes is required to be matched for detection. Therefore, when four columns of equidistantly distributed test holes are arranged on the test board, another detection device with four contact pieces is required for coordinated detection.

[0004] With respect to the above-mentioned related technologies, the following defects are found: the number of contacts on the existing test device is a fixed value, so this structure is often not easy to adjust the number of contacts. Only when the number of test hole columns opened on the test board is consistent with the number of contacts can the switch discharge tube be tested in coordination. Utility Model Content

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a detection device for a switch discharge tube. Figure 1 A detection device for a switch discharge tube includes a test platform 1, a plurality of equally spaced contact pieces 2 and a test board 3, wherein the contact pieces 2 and the test board 3 are both arranged on the test platform 1, a switch discharge tube is placed on the test board 3, and the contact pieces 2 are used to detect the switch discharge tube.

[0033] Reference Figure 1 and Figure 2A lifting frame 11 is provided on the test platform 1. It is assumed that one end of the test platform 1 provided with the lifting frame 11 is the upper end of the test platform 1. The lifting frame 11 is arranged parallel to the upper end of the test platform 1. Lifting bolts 111 are passed through both ends of the lifting frame 11. Adjusting nuts 112 are provided on the lifting bolts 111. The adjusting nuts 112 are located below the lifting frame 11 and abut against the lower end of the lifting frame 11. It is assumed that the two ends of the lifting frame 11 provided with the lifting bolts 111 are the left and right ends of the lifting frame 11 respectively.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A plurality of equally spaced contact pieces 2 are arranged on the lifting frame 11, and an electrode lead-out piece 21 is arranged at the upper end of the contact piece 2. The electrode lead-out piece 21 includes a fixing plate 211 and a lead-out block 212. The lead-out block 212 is used to connect with the cable. The fixing plate 211 abuts against the upper end of the contact piece 2. Fixing bolts 22 are passed through both ends of the fixing plate 211. The fixing bolts 22 pass through the fixing plate 211, the contact piece 2 and the lifting frame 11 in sequence. A fastening nut 23 is provided on the fixing bolt 22. The fastening nut 23 is located below the lifting frame 11 and abuts against the lower end of the lifting frame 11, so that the contact piece 2 is fixed to the lifting frame 11 through the cooperation between the fixing bolt 22 and the fastening nut 23. At the same time, the electrode lead-out piece 21 can also be fixed to the contact piece 2 through the cooperation between the fixing bolt 22 and the fastening nut 23. The lead-out block 212 is located between the two fixing bolts 22 and is integrally formed with the fixing plate 211.

[0035] Reference Figure 1 and Figure 3 An adjustment channel 113 is opened on the lifting frame 11 in the direction from left to right, and the fixing bolt 22 is passed through the adjustment channel 113. Since two fixing bolts 22 are provided in this embodiment, two adjustment channels 113 are opened on the lifting frame 11 for the left and right sliding of the fixing bolts 22, which is conducive to the left and right sliding of the contact piece 2 on the lifting frame 11.

[0036] Reference Figure 1 and Figure 2 In order to fix the contact piece 2 on the lifting frame 11 to contact the switch discharge tube and detect the switch discharge tube, a plurality of equally distributed embedding grooves 114 are opened at the upper end of the lifting frame 11. The embedding grooves 114 are perpendicularly arranged to the adjustment channel 113 and communicate with the adjustment channel 113. In this embodiment, according to the length of the lifting frame 11 from left to right, nine equally distributed embedding grooves 114 are preferably arranged at the upper end of the lifting frame 11. Therefore, in this embodiment, nine contact pieces 2 are preferably arranged on the lifting frame 11, and the contact pieces 2 correspond to the embedding grooves 114 one by one.

[0037] Reference Figure 1A copper plate 12 is placed on the test platform 1, and the test board 3 is in contact with the upper end of the copper plate 12. A plurality of equidistantly distributed test holes 31 are opened on the test board 3. The test hole 31 is used to place the switch discharge tube. The switch discharge tube is in contact with the copper plate 12 through the test hole 31. After the test board 3 is placed on the copper plate 12, a push plate 32 is fixed above the end of the test board 3 away from the contact piece 2 by bolts. The operator pushes the push plate 32 fixed on the test board 3 to move the test board 3 toward the direction of the contact piece 2, that is, the switch discharge tube placed in the test hole 31 is pushed to move toward the direction of the contact piece 2.

[0038] Reference Figure 1 A limit plate 13 is fixed by bolts at a position near the left side of the upper end of the test platform 1, so that the left side of the test board 3 placed on the copper plate 12 can abut against the limit plate 13, which is beneficial to improving the stability of pushing the test board 3, and a drop opening 14 is opened at the end of the test platform 1 near the contact piece 2, and the drop opening 14 is not aligned with the contact piece 2. A collection box 15 is placed below the drop opening 14. As the test board 3 is pushed toward the direction of the contact piece 2, when the switch discharge tube on the test board 3 contacts the contact piece 2, the test board 3 continues to move, and the tested switch discharge tube falls into the collection box 15 through the drop opening 14.

[0039] The implementation principle of the detection device for switch discharge tubes in the embodiment of the present application is as follows: according to the number of switch discharge tubes to be tested, a test plate 3 with a corresponding number of test holes 31 is selected. For example, according to the number of switch discharge tubes, a test plate 3 with three columns of test holes 31 equidistantly distributed is selected, and three contact pieces 2 originally concentrated on the right side of the lifting frame 11 are moved toward the left side of the lifting frame 11, and the three contact pieces 2 are respectively placed in the first three embedding grooves 114 from left to right on the lifting frame 11, and then the contact pieces 2 are fixed to the embedding grooves 114 by tightening the fastening nuts 23;

[0040] The switch discharge tube is placed in three columns of equally spaced test holes 31, and the height of the lifting frame 11 is adjusted by rotating the adjusting nut 112 so that the contact piece 2 can contact the switch discharge tube. Then the lead-out block 212 is connected to the cable, and the push plate 32 fixed on the test board 3 is pushed, and the test board 3 moves against the limit plate 13, so that the switch discharge tube in the test hole 31 contacts the contact piece 2 for detection. As the test board 3 is pushed, the switch discharge tube after the test falls through the drop port 14 into the collection box 15, and the switch discharge tube that has completed the test is collected.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
