Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to a testing isolation board and a testing system comprising the same. Background Art

[0002] In existing light panel testing, cable ties are typically used to secure the sample to the isolation board. This method is inefficient and can cause surface wear on the sample. Furthermore, the sample must be connected to the power source via an extension cord, which complicates the wiring harness. This is especially true when testing large samples and combining multiple isolation boards simultaneously, making it difficult to manage the wiring harnesses between boards and external wiring harnesses. Therefore, a test isolation board and testing system that is easy to assemble and disassemble and offers high testing efficiency is needed. Utility Model Content

[0003] In order to solve the technical problems of low test efficiency and difficulty in sample fixation in the prior art of lamp board testing, the utility model provides a test isolation plate and a test system including the same to solve the above problems.

[0004] The utility model proposes a test isolation plate, comprising a mounting plate with a plurality of mounting holes on the surface and a limiting column assembled at the mounting holes; the limiting column can reciprocate between an upper limit position and a lower limit position relative to the mounting plate, and the limiting column located at the lower limit position forms a limiting area that imitates the shape of the sample to be tested, so that the limiting column located at the upper limit position fixes the sample to be tested.

[0005] Furthermore, a plurality of plugs are provided on the edge of the mounting plate.

[0006] Furthermore, the limiting column includes a column body, an elastic limiting plate located in the middle of the column body, and limiting parts located at both ends of the column body. The two limiting parts are respectively located at both ends of the mounting hole. When the limiting column is located at the upper limit position, the elastic limiting plate is located above the mounting plate; when the limiting column is located at the lower limit position, the elastic limiting plate abuts against the lower surface of the mounting plate, and the limiting part at the upper end of the column body abuts against the upper surface of the mounting plate.

[0007] Furthermore, the elastic limiting piece includes a stopper plugged into the side surface of the column and an elastic member abutting between the stopper and the column.

[0008] Furthermore, the limiting member is a protrusion fixed on the column and capable of abutting against the surface of the mounting plate.

[0009] Furthermore, the limiting member includes a protrusion that slides with the column and can abut against the surface of the mounting plate, and a telescopic spring connecting the column and the protrusion. The telescopic spring is arranged along the axial direction of the column, and the protrusion is located at one end of the telescopic spring close to the elastic limiting piece.

[0010] Furthermore, the lower surface of the stopper is an inclined surface that gradually slopes upward from the side connected to the column to the side away from the column.

[0011] The utility model also provides a test system, which includes a plurality of the above-mentioned test isolation plates, and the mounting plates of adjacent test isolation plates are arranged in close contact.

[0012] The utility model also provides a test system, which comprises a plurality of the above-mentioned test isolation boards, wherein the plugs of adjacent test isolation boards are connected in sequence.

[0013] Furthermore, the two parallel sides of each mounting plate have matching sliding grooves and sliding edges, and the sliding grooves and sliding edges of two adjacent mounting plates are plugged into each other.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model fixes the sample to be tested by arranging a plurality of limit columns that can move up and down on the mounting plate, and using the concave and convex adjustment of the limit columns to clamp the outer edge of the sample to be tested. There is no need to tie it with a cable tie, which not only avoids wear on the sample to be tested, but also achieves uniform and stable fixation of any sample to be tested.

[0016] (2) The utility model provides a plug on the mounting plate. When two mounting plates are connected, the plugs of the two mounting plates can be connected. The plug provided on the mounting plate is used to connect with an external extension harness. In this way, the sample to be tested is embedded in different mounting plates according to the nodes, and then they are spliced. No matter how many nodes the sample to be tested has, only a few external extension harnesses are needed to connect the power supply and communication equipment, and embedding the sample to be tested in the mounting plate is also neater.

DETAILED DESCRIPTION

[0026] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] Example 1

[0028] like Figure 1-Figure 3 As shown, a test isolation plate includes a mounting plate 1 having a plurality of mounting holes 101 on its surface and a limiting column 2 assembled at the mounting holes 101; the limiting column 2 can reciprocate between an upper limit position and a lower limit position relative to the mounting plate 1, and the limiting column 2 at the lower limit position forms a limiting area 3 that is shaped like a sample to be tested 4, so that the limiting column 2 at the upper limit position fixes the sample to be tested 4.

[0029] The limit post 2 can be fixed in both the upper limit position and the lower limit position to keep it in position. For the sake of distinction, the present invention names the limit post 2 at the upper limit position as the outer limit post 6 and the limit post 2 at the lower limit position as the inner limit post 5.

[0030] The limiting posts 2 are preferably arranged in an array on the mounting plate 1. The denser the distribution of the limiting posts 2, the more accurate the positioning. Figure 2 The figure shows the state of each limit column 2 when fixing a certain shape of light board. There are multiple concave limit areas 3 in the center of the mounting plate 1 for mounting different types of test samples 4. When the test sample 4 is mounted on the mounting plate 1, Figure 2 The inner limiting column 5 is located below the sample 4 to be tested, and the outer limiting column 6 is located outside the sample 4 to be tested. The outer limiting column 6 located at the edge of the limiting area 3 fixes the sample 4 to be tested (such as Figure 3 shown).

[0031] The limiting column 2 may include, but is not limited to, a column body 201, an elastic limiting piece 202 located in the middle of the column body 201, and limiting members located at both ends of the column body 201. The two limiting members are located at both ends of the mounting hole 101. When the limiting column 2 is at the upper limit position, the elastic limiting piece 202 is located above the mounting plate 1. When the limiting column 2 is at the lower limit position, the elastic limiting piece 202 abuts against the lower surface of the mounting plate 1, and the limiting member at the upper end of the column body 201 abuts against the upper surface of the mounting plate 1. The elastic limiting piece 202 is elastic and can pass through the mounting hole 101 when contracted, but cannot enter the mounting hole 101 when expanded, thereby abutting against the end surface of the mounting plate 1.

[0032] Normally, the limit column 2 is located at the upper limit position, and the elastic limit piece 202 is located above the mounting plate 1. In the absence of external force, the elastic limit piece 202 is in a free expansion state, so the elastic limit piece 202 will not enter the mounting hole 101, and the limit column 2 can maintain the upper limit position. When it is necessary to press the limit column 2 downward, the elastic limit piece 202 is deformed and shrinks due to the external force in the contraction direction, thereby entering the mounting hole 101 until it completely passes through the mounting hole 101 and is stuck on the lower surface of the mounting plate 1. The limit piece at the upper end of the limit column 2 can limit the downward movement, so that the limit column 2 remains at the lower limit position, and the sample to be tested 4 can be stably placed on the inner limit column 5. The limit piece at the lower end of the limit column 2 is used to limit the upper limit of the limit column 2.

[0033] The elastic limiting piece 202 and the column 201 can be installed in a retractable structure similar to an umbrella. Specifically, the elastic limiting piece 202 includes a stopper 2021 plugged into the side of the column 201 and an elastic member 2022 abutting between the stopper 2021 and the column 201. Figure 4-Figure 6 As shown, a groove is provided on the side of the column 201, the stopper 2021 is stuck in the groove, and the elastic member 2022 abuts between the groove and the stopper 2021. In the free state, the stopper 2021 is pushed out of the groove by the elastic member 2022, so that it can be stuck on the surface of the mounting plate 1. When it is necessary to move the limit column 2 upward or downward, the stopper 2021 is manually pressed.

[0034] The limiting member structures at both ends of the column 201 can be the same or different. In one embodiment, the limiting member can be a protrusion 203 fixed on the column 201 and capable of abutting against the surface of the mounting plate 1, that is, the protrusion 203 cannot enter the mounting hole 101.

[0035] Since the limiting column 2 is normally in the upper limit position, in order to enable the limiting column 2 to be quickly reset to the upper limit position from the lower limit position, the limiting member located at the upper end of the column 201 is preferably of the following structure: comprising a protrusion 203 that slides with the column 201 and can abut against the surface of the mounting plate 1, and a telescopic spring 204 connecting the column 201 and the protrusion 203, the telescopic spring 204 being arranged along the axial direction of the column 201, and the protrusion 203 being located at one end of the telescopic spring 204 close to the elastic limiting piece 202. The protrusion 203 here is still used to abut against the surface of the mounting plate 1, and the telescopic spring 204 can be located inside the column 201 or can be sleeved outside the column 201. When the elastic limiting piece 202 is located below the mounting plate 1, the telescopic spring 204 contracts (such as Figure 5 As shown), when the elastic limiting piece 202 is pressed, the column 201 is pushed upward under the elastic force of the telescopic spring 204.

[0036] In a further design, the lower surface of the stopper 2021 is a slope that gradually slopes upward from the side connected to the column 201 to the side away from the column 201 (e.g. Figure 5 and Figure 6 When the limit column 2 needs to be switched from the upper limit position to the lower limit position, it is only necessary to directly press the column 201.

[0037] Example 2

[0038] On the basis of the first embodiment, a plurality of plugs 7 are provided on the edge of the mounting plate 1. Figure 1-Figure 3 As shown, the mounting plate 1 is a rectangular structure, with plugs 7 provided on both the long and short edges of the mounting plate 1. When two mounting plates 1 are connected, the plugs 7 of the two mounting plates 1 can be connected. The plugs 7 provided by the mounting plates 1 are used to connect to external extension harnesses. In this way, the test sample 4 can be embedded in different mounting plates 1 according to the nodes and then spliced ​​together. Regardless of the number of nodes on the test sample 4, only a few external extension harnesses are needed to connect the power supply and communication equipment. Moreover, embedding the test sample 4 in the mounting plate 1 is also more neat.

[0039] Example 3

[0040] A test system comprises a plurality of the above-mentioned test isolation panels, with the mounting plates 1 of adjacent test isolation panels arranged in close proximity. The test system can be combined to form isolation panels of any size, meeting the test requirements of control units of any size composed of multiple light panels.

[0041] As a preferred Figure 7 As shown, the two parallel sides of each mounting plate 1 have matching sliding grooves 102 and sliding edges 103 , and the sliding grooves 102 and sliding edges 103 of two adjacent mounting plates 1 are plugged into each other.

[0042] Example 4

[0043] A test system includes the test isolation board described in the second embodiment, wherein the plugs 7 of adjacent test isolation boards are connected in sequence.
