Description

Technical Field

[0001] The present invention belongs to the technical field of semiconductor detection equipment, and particularly relates to a rapid plugging probe device for a PCB board. Background Art

[0002] Test probes are mainly used for the electrical performance detection of electronic products. With the development of electronic products, they have been widely used in fields such as aviation, aerospace, military, medical, optoelectronics, etc., and have played a great role in the development of modern science and technology.

[0003] When test probes are applied, it is often necessary to install multiple of them on a PCB board. After they are combined with the PCB board, the next detection work can be carried out.

[0004] However, at present, the installation of test probes on a PCB board is mainly completed manually. This operation has the following problems: (1) Since the volume of the test probe is small, when a person inserts it into a preset hole on the PCB board, if it is not aligned with the hole, it is easy to bend it during the insertion process, and it is necessary to replace the test probe and operate again, resulting in a large waste; (2) The preset holes on the PCB board are generally relatively dense. After a certain number of test probes are inserted, the working space that the staff can exert will become smaller when inserting the test probes later, and it is easy to squeeze the already installed test probes; (3) Manually loading test probes onto the PCB board has a low work efficiency and is difficult to adapt to large-scale industrial production operations. Summary of the Invention

[0033] In the description of the present invention, if the first and second are described only for the purpose of distinguishing technical features, they cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0035] As Figure 1 and Figure 2 shown, a quick insertion probe device for a PCB board according to the present invention mainly includes: a bottom plate 8, a support block, a pressing block, and a top head 14. Among them, the support block is fixed on the bottom plate 8 by bolts, and at least one row of jacks 4 for placing probes is designed on the support plate; the pressing block is placed between the bottom plate 8 and the support plate; the top head 14 is threadedly assembled on the bottom plate 8 and is used to press tightly the pressing block.

[0036] Before inserting the test probes into the PCB board, first insert a test probe into each jack 4 on the support block, and then align and press the PCB board against the support block before proceeding with the next step of inserting the test probes.

[0037] When performing the work of inserting the test probes, screw the top head 14 into the bottom plate 8. At this time, the top of the top head 14 will push the pressing block upward, and the pressing block will push the test probes in the jacks 4 into the PCB board, thus completing the insertion of the test probes.

[0038] As Figure 3 shown, in a quick insertion probe device for a PCB board according to the present invention, it further includes a base 1. The bottom plate 8 is fixed on the base 1 by bolts, and a U-shaped groove 11 for screwing the top head 14 is reserved on the base 1.

[0039] The staff can complete the tightening and loosening actions of the top head 14 in the U-shaped groove 11, and the operation is relatively convenient.

[0040] As Figure 1 shown, in a quick insertion probe device for a PCB board according to the present invention, the support block includes a support plate 5 and two support legs 9. Among them, the support legs 9 are fixed on the bottom plate 8 by bolts; the support plate 5 is integrally formed with the two support legs 9 and is fixed on the tops of the two support legs 9, and the jacks 4 are designed on the support plate 5.

[0041] A channel is formed between the two support legs 9, which is convenient for assembling the pressing block and is also used to limit the pressing block to ensure that the pressing block can be limited to move up and down between the two support legs 9 under the action of the top head 14.

[0042] As Figure 1 shown, in a quick insertion probe device for a PCB board according to the present invention, two rows of jacks 4 are provided on the support plate 5.

[0043] The reserved holes on the PCB board for inserting test probes are generally designed in rows. Two rows of jacks 4 are designed on the support plate 5, and the insertion of two rows of test probes on the PCB board can be completed at one time, thus improving production efficiency.

[0044] Combined with Figure 2 , in a quick insertion probe device for a PCB board according to the present invention, the pressing block includes a horizontal pressing block 12 and two vertical pressing blocks 6. Among them, the horizontal pressing block 12 is placed between the support plate 5 and the bottom plate 8; the two vertical pressing blocks 6 are integrally formed on the upper side of the horizontal pressing block 12, and the two vertical pressing blocks 12 are located below the two rows of jacks 4.

[0045] The top head 14 jacks up the horizontal pressing block 12. At the same time, the two vertical pressing blocks 6 smoothly press the test probes in the two rows of jacks 4 into the PCB board.

[0046] As Figure 1 shown, in a quick insertion probe device for a PCB board according to the present invention, it further includes a first limiting block 2 and a second limiting block 7. Among them, the first limiting block 2 and the second limiting block 7 are fixed on the base 1 by bolts; and the first limiting block 2 and the second limiting block 7 are arranged at 90°, and the bottom plate 8 is arranged between the first limiting block 2 and the second limiting block 7.

[0047] Two adjacent sides of the bottom plate 8 are respectively pressed tightly against the side parts of the first limiting block 2 and the second limiting block 7, which is convenient for positioning and installation to ensure that it will not shake during use.

[0048] As Figure 1 shown, in a quick insertion probe device for a PCB board according to the present invention, a compression spring 10 is arranged between the support plate 5 and the bottom plate 8.

[0049] When the horizontal pressing block 12 rises, the compression spring 10 is compressed. When the top head 13 screws out of the bottom plate 8, the horizontal pressing block 12 can quickly reset under the action of the elastic force of the compression spring 10, so as to pre-install the test probes before a single operation.

[0050] As Figure 1 shown, in a quick insertion probe device for a PCB board according to the present invention, two limiting grooves 13 are arranged on the lower side of the support plate 5, and the two vertical pressing blocks 6 are located in the two limiting grooves 13.

[0051] The two vertical pressing blocks 6 move up and down in the two limiting grooves 13, which can ensure that they apply force to the test probes in the positive direction and push them into the PCB board without bending.

[0052] As Figure 1 shown, in a quick insertion probe device for a PCB board according to the present invention, the support plate 5 is a stepped structure with a lower middle and higher ends. Two strip-shaped grooves 3 are arranged at the middle of the support plate 5, and the two rows of jacks 4 are located in the two strip-shaped grooves 3.

[0053] The PCB board is pressed tightly at the middle of the support plate 5 for convenient positioning. The test probe is actually located in the strip groove 3 to ensure that when the PCB board is pressed tightly at the middle of the support plate 5, it will not press the test probe pre-installed in the jack 4, preventing extrusion and deformation.

[0054] In summary, compared with the prior art, a quick insertion and installation probe device for a PCB board of the present invention has the following advantages: (1) For a quick insertion and installation probe device for a PCB board of the present invention, the test probe is inserted into the support block, the PCB board is aligned with the support block and pressed tightly, and then the test probe inserted into the support block is pushed into the preset hole on the PCB board by the top head, and the installation can be completed. The operation is relatively accurate, avoiding the problem that the test probe is prone to bending; (2) For a quick insertion and installation probe device for a PCB board of the present invention, multiple test probes are installed on the support block, and multiple test probes can be pushed into the PCB board at one time, overcoming the problems of small working space and difficult operation when inserting and installing test probes one by one, and improving the work efficiency at the same time.
