Background Technique

[0002] With the trend of miniaturization and high - performance of integrated circuits, their internal structures are becoming more and more complex and the conductive lines are becoming more and more dense. This high - density layout increases the risk of short - circuits between lines, affecting the reliability and service life of integrated circuits. As the line spacing decreases, the short - circuit problem becomes increasingly prominent. Short - circuits not only cause circuit function failures but may also lead to safety accidents. For this reason, we have proposed a short - circuit - proof integrated circuit board. Content of the Utility Model

An insulating mounting foot pad is placed below the mounting hole of the integrated circuit. A quick - mounting device is inserted into the mounting hole, and the quick - mounting device is connected to the insulating mounting foot pad, so that the integrated circuit board is fixed on the surface of the insulating mounting board. The insulating mounting foot pad is installed on the insulating mounting board through self - tapping screws, and the insulating mounting foot pad and the insulating mounting board are connected through self - tapping screws.

[0005] Preferably, the insulating mounting foot pad consists of an insulating mounting foot pad body and a horizontally protruding part. An insulating mounting foot pad limiting groove is opened at the upper end of the insulating mounting foot pad body, and an insulating mounting foot pad self - tapping screw mounting position is opened on the horizontally protruding part. The insulating mounting foot pad self - tapping screw mounting position cooperates with the self - tapping screw for locking.

[0006] Preferably, the quick installation device is composed of a body hand-twisting part cooperating with the main body, a limit card, and a clamping and cooperating limit part cooperating sleeve device. The upper end of the hand-twisting part cooperating with the main body is connected with a twisting part. A limit part is integrally formed on the outer side surface of the hand-twisting part cooperating with the main body. A limit groove is opened on the outer side of the limit part cooperating sleeve device for clamping and cooperating with the limit part. A limit cavity for inserting a spring is opened at the lower end of the hand-twisting part cooperating with the main body. The bottom of the spring is connected with a limit card, and the limit card is fixedly connected with an installation groove cooperating part. A limit groove is opened on the outer side of the limit part cooperating sleeve device, and the limit part is in clamping and cooperating with the limit groove. By rotating the hand-twisting part to control the hand-twisting part cooperating with the main body, the limit part fixed on the outer side of the hand-twisting part cooperating with the main body is driven to rotate, so that the limit part rotates along the limit groove for clamping and cooperating.

[0007] Preferably, a rectangular notch is arranged on one side of the limit groove of the insulating installation foot pad. A cooperating cavity of the insulating installation foot pad is opened at the bottom of the limit groove of the insulating installation foot pad. The cooperating cavity of the insulating installation foot pad is in clamping connection with the installation groove cooperating part. When the hand-twisting part is rotated and pressed, the spring and the integrated circuit board are compressed. At this time, the installation groove cooperating part rotates accordingly.

[0008] The preferred connecting limit card is composed of a circular boss at the top for sleeving the spring and a limit round block at the bottom.

[0009] Preferably, the limit groove is an arc-shaped groove opened on the outer side of the annular limit part cooperating sleeve device.

[0010] Compared with the prior art, the utility model provides a short-circuit prevention integrated circuit board, which has the following beneficial effects:

[0011] 1. For this short-circuit prevention integrated circuit board, through the installation hole positions reserved on the surface of the integrated circuit board, insulating installation foot pads and quick installation devices with suitable sizes and specifications are selected to fix the integrated circuit board on the upper surface of the insulating installation board.

[0012] 2. For this short-circuit prevention integrated circuit board, self-tapping screws can be selected to fix the quick installation device at a convenient position. Because each integrated circuit board is relatively independent and has a large gap, and no shell is provided, the integrated circuit board is suspended in the air as a whole due to the device characteristics, so it has fast heat dissipation, is convenient for cleaning, disassembly and repair.

When one of the integrated circuit boards is damaged, the damaged integrated circuit board can be replaced without affecting other integrated circuit boards, which is convenient for replacing the damaged integrated circuit board; at the same time, self-tapping screws 4 can be selected to fix the quick mounting device 5 at a convenient position. Because each integrated circuit board 1 is relatively independent and has a large gap, and there is no shell, the integrated circuit board 1 is suspended in the air as a whole due to the device characteristics, so it has fast heat dissipation, is convenient for cleaning, disassembly and repair; the existing short-circuit protection circuit can be selected for connection between them, so as to achieve the envisioned circuit function.
