Description

Technical Field

[0001] The invention belongs to the technical field of circuit detection equipment, and in particular is a miniaturized electronic circuit testing tool. Background Art

[0002] An integrated circuit is a miniature electronic device or component. Using a certain process, the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit are interconnected and made on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit function. It is generally installed on a circuit board, and the circuit test is completed by testing the circuit board.

[0003] In the prior art, test equipment is used to test circuit boards. In the general process, the circuit board is fixed with a test fixture, and then the test points are directly contacted with the help of probes. The basic state of the circuit is judged by scraping and measuring the parameters of the multimeter. However, the fixtures in the prior art generally perform limit clamping from the outside of the circuit board. For some irregular circuit boards, the clamping effect may not be ideal. In addition, the side clamping method has a small contact surface. If the operation is improper, it is easy to cause the circuit board to be squeezed and damaged. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the present case. Summary of the invention

[0004] Technical problem solved by the present invention: The purpose of the present invention is to provide a miniaturized electronic circuit testing tool to solve the problem that the clamping effect of the clamping tool proposed in the above background technology is not ideal.

[0007] Furthermore, a plurality of slideways 17 with trapezoidal cross-sections are provided at the top end of the transverse clamping plate 2, and matching sliders 18 are installed at the bottom end of the sliding plate 3, and the sliding plate 3 forms a sliding connection with the transverse clamping plate 2 through the cooperation between the sliders and the slideways.

[0008] Furthermore, by moving the two lateral clamping plates 2 close to the outer edge of the circuit board for preliminary clamping, the pull rod 7 is pulled to drive the fixed plate 15 to overcome the movement of the spring telescopic rod 14, thereby raising the pressure block 11. At this time, the sliding plate 3 is moved so that the pressure block 11 below it is located above the circuit board where no circuit components are installed. Then the pull rod 7 is released so that the pressure block 11 is pressed on the top of the circuit board under the thrust of the spring telescopic rod 14, thereby completing the clamping.

[0009] Furthermore, an image display screen 10 is embedded and installed on one side of one end of the detection box 1, and a data display screen 12 is embedded and installed on the other side of one end of the detection box 1, and a camera assembly 8 is installed on the top of one end of the detection box 1;

[0010] A plurality of placement holes 9 are provided at the top of the detection box 1 , and the plurality of placement holes 9 are distributed at equal intervals at the top of the detection box 1 .

[0011] Furthermore, when the detection box 1 is working, the data is displayed on the data display screen 12. The placement hole 9 on the detection box 1 is used to temporarily place the detection needle for subsequent use. At the same time, a camera component 8 is installed at one end of the detection box 1 to shoot the top of the circuit board, and the captured content is enlarged and displayed on the image display screen 10.

[0012] Furthermore, the adjustment component includes a rotating rod 6, which is rotatably installed on one side of the placement table 5, and one end of the rotating rod 6 extends to the outside of the placement table 5 and is installed with a knob. The outer wall of the rotating rod 6 inside the placement table 5 is sleeved with two moving blocks 13, and the top ends of the moving blocks 13 are fixed to the bottom end of the transverse clamping plate 2 through connecting parts; the two ends of the outer wall of the rotating rod 6 are respectively provided with external threads in opposite directions, and the inner walls of the moving blocks 13 are respectively provided with internal threads matching them, and the connection method between the moving blocks 13 and the placement table 5 is a sliding connection.

[0013] Furthermore, since the moving block 13 is threadedly matched with the rotating rod 6 and the moving block 13 is restricted and guided by the placement table 5, the two moving blocks 13 can move toward each other, thereby driving the transverse clamping plates 2 to move closer to each other, thereby realizing the clamping function of the transverse clamping plates 2.

[0014] Furthermore, a plurality of anti-slip strips are embedded and installed on the top of the detection box, and the top of the anti-slip strips and the top of the detection box are on the same horizontal plane.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By moving the two transverse clamping plates close to the outer edge of the circuit board and subsequently adjusting the position of the sliding plate, the pressure block is placed above the circuit board where no circuit components are installed. Then, a spring telescopic rod is used to apply a thrust to the fixed plate, causing the pull rod to move downward, thereby causing the pressure block to be pressed at a suitable position above the circuit board, thereby completing the positioning of the circuit board. Compared with the traditional method of simply relying on transverse clamping plates for clamping, the method has a higher degree of adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
