Description

Technical Field

[0001] The utility model relates to the technical field of electronic component testing, in particular to a connecting device for electronic component testing. Background Art

[0002] An electronic component is a basic element in an electronic circuit. It is usually individually packaged and has two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with a specific function. One of the common ways to connect electronic components is to solder them to a printed circuit board. The printed circuit board usually needs to be encapsulated and tested. For the test of the printed circuit board, it is usually necessary to connect the electronic components on the printed circuit board to an external test device for testing. In the prior art, the electronic components on the printed circuit board are usually connected to the external test device by wire soldering. After the test, the wire is separated from the electronic components on the printed circuit board, resulting in low test efficiency. Content of the Utility Model

[0003] In view of the above problems in the prior art, the utility model provides a connecting device for electronic component testing, which solves the problem that in the prior art, the electronic components on the printed circuit board are usually connected to the external test device by wire soldering, and after the test, the wire is separated from the electronic components on the printed circuit board, resulting in low test efficiency.

[0004] In order to achieve the above utility model purpose, the technical scheme adopted by the utility model is as follows:

[0005] Provide a connecting device for electronic component testing, including a base, a needle board, a mounting board and a pressing board. A first guiding component is arranged on the top of the base. A first buffer is sleeved on the first guiding component. One end of the first guiding component away from the base penetrates through the needle board. The needle board is located above the first buffer. A second guiding component is arranged on the base. A second buffer is sleeved on the second guiding component. One end of the second guiding component away from the base penetrates through the mounting board. The second buffer is located below the mounting board. A mounting position is arranged on the mounting board. A bracket is arranged on the base. A fixing plate is arranged on the bracket. A driving mechanism is arranged on the fixing plate. The output end of the driving mechanism is connected to the top of the pressing board. The pressing board is located directly above the mounting board.

[0006] In some embodiments, the needle board includes a first board body and a plurality of probes penetrating through the first board body.

[0007] In some embodiments, the first guiding assembly includes two symmetrically arranged first guiding rods. One end of each first guiding rod is threadedly connected to the base, and the other end of each guiding rod is threadedly connected with a first limiting portion.

[0008] In some embodiments, the second guiding assembly includes two symmetrically arranged second guiding rods. One end of each second guiding rod is threadedly connected to the needle plate, and the other end of each second guiding rod is threadedly connected with a second limiting portion.

[0009] In some embodiments, a mounting groove is concavely formed at the top of the mounting plate, and a through groove penetrating the mounting plate is concavely formed at the bottom of the mounting groove. The through groove and the mounting groove constitute the mounting position.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The driving mechanism drives the pressing plate to move downward along the second guiding assembly. When the pressing plate moves downward and contacts and presses the mounting plate, the pressing plate confines the printed circuit board within the mounting position. As the pressing plate continues to move downward, it drives the mounting plate to move downward along the second guiding assembly. When the mounting plate moves downward, it presses the second buffer, driving the electronic components of the printed circuit board to contact and press the probes on the needle plate, so that the metal contacts of the electronic components of the printed circuit board are connected to the corresponding probes on the needle plate. The force received by the probes of the needle plate compresses the first buffer, avoiding the violent collision between the probes of the needle plate and the metal contacts of the electronic components, which may cause damage to the printed circuit board or the probes of the needle plate. After the test is completed, the driving mechanism drives the pressing plate to move upward in the vertical direction, and the second buffer drives the mounting plate to move upward and reset; it can realize the automatic separation of the metal contacts of the electronic components of the printed circuit board from the corresponding probes of the needle plate, which is convenient for installation and disassembly and can improve the test efficiency of the electronic components of the printed circuit board.

[0018] Embodiment 1

[0019] The embodiment of the present application provides a connection device for testing electronic components. As Figure 1 shown, it includes a base 1, a needle board 2, a mounting plate 3 and an extrusion plate 4. A first guiding component 5 is arranged on the top of the base 1. A first buffer 6 is sleeved on the first guiding component 5. One end of the first guiding component 5 away from the base 1 penetrates through the needle board 2. The needle board 2 is located above the first buffer 6. A second guiding component 7 is arranged on the base 1. A second buffer 8 is sleeved on the second guiding component 7. One end of the second guiding component 7 away from the base 1 penetrates through the mounting plate 3. The second buffer 8 is located below the mounting plate 3. An installation position is arranged on the mounting plate 3. A bracket 9 is arranged on the base 1. A fixed plate 10 is arranged on the bracket 9. A driving mechanism 11 is arranged on the fixed plate 10. The output end of the driving mechanism 11 is connected to the top of the extrusion plate 4. The extrusion plate 4 is located directly above the mounting plate 3.

[0020] In the embodiment of the present application, the probes 22 on the needle board 2 are arranged according to the distribution of the electronic components on the printed circuit board. The printed circuit board is installed through the installation positions provided on the mounting plate 3, and the installation positions are adapted to the printed circuit board. After installation, the driving mechanism 11 drives the pressing plate 4 to move downward in the vertical direction. The pressing plate 4 moves downward and contacts and presses the mounting plate 3. The pressing plate 4 confines the printed circuit board within the installation position to prevent the printed circuit board from shaking. The pressing plate 4 continues to move downward to drive the mounting plate 3 to move downward along the second guiding component. The mounting plate 3 moves downward to press the second buffer 8 to drive the electronic components of the printed circuit board to contact and press the probes 22 on the needle board 2, so that the metal contacts of the electronic components of the printed circuit board are connected to the corresponding probes 22 on the needle board 2. The force received by the probes 22 of the needle board 2 compresses the first buffer 6, and the first buffer 6 absorbs the force received by the probes 22 to prevent the probes 22 of the needle board 2 from colliding violently with the metal contacts of the electronic components, resulting in damage to the printed circuit board or the probes 22 of the needle board 2. The electronic components on the printed circuit board can be tested respectively through an external testing device. After the test is completed, the driving mechanism 11 drives the pressing plate 4 to move upward in the vertical direction, and the second buffer 8 drives the mounting plate 3 to move upward and reset, which can realize the automatic separation of the metal contacts of the electronic components of the printed circuit board from the corresponding probes 22 of the needle board 2. The installation and disassembly are convenient, and the testing efficiency of the electronic components of the printed circuit board can be improved.
