Description

Technical Field

[0001] The utility model relates to the technical field of circuit antistatic technology, in particular to a mainboard interface antistatic device with a plastic shell. Background Art

[0002] Computer motherboards, especially military laptop motherboards, are designed to miniaturize and visualize circuits, which plays an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. In general, circuit boards can be called printed circuit boards or printed circuit boards. Circuit boards are divided into three major categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards. Circuit boards are widely used in the fields of electronics and electrical technology. However, static electricity often occurs in circuit boards. When static electricity passes through the equipment rapidly at high voltage and low current, this process may cause abnormal circuit status, damage components, etc., which will cause equipment failures and, in severe cases, damage the life safety of users. In order to prevent static safety accidents, anti-static design is required.

[0003] In the prior art, since the shell of the computer motherboard is made of plastic, which is a non-conductive material, there is no conductive shell to release static electricity. Anti-static protection relies on adding ESD or TVS tubes on the circuit board to absorb and protect the motherboard interface. The life of this device is very short, and when static electricity is discharged, all static electricity will flow to the motherboard, which will interfere with the motherboard and cause blue screen, restart, freeze, etc.

[0004] Therefore, it is of great significance to study an antistatic device for computer motherboard interface with a plastic shell having good antistatic performance and long service life. Utility Model Content

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A computer motherboard interface anti-static device with a plastic shell comprises a computer motherboard, a computer motherboard interface, a conductive aluminum block and a beryllium copper shrapnel; the computer motherboard interface is mounted on the computer motherboard, the conductive aluminum block is fixedly connected above the computer motherboard interface, and the beryllium copper shrapnel is mounted on the top of the computer motherboard interface and is located below the conductive aluminum block; a plurality of screw holes are arranged on the body of the conductive aluminum block for fixing wires and directing the generated static current to the ground.

[0008] As the preferred technical solution:

[0009] In the anti-static device for the computer motherboard interface with a plastic shell as described above, the conductive aluminum block is buckled on the computer motherboard interface, and connecting columns are provided on both sides. Screws pass through the connecting columns and are connected to the computer motherboard, so that the computer motherboard interface is fixed to the conductive aluminum block.

[0010] In the computer motherboard interface anti-static device with a plastic shell as described above, the beryllium copper shrapnel is connected to the computer motherboard interface via an elastic connecting piece, and the connection method is that the beryllium copper shrapnel and the elastic connecting piece are riveted or welded, and the elastic connecting piece and the computer motherboard interface are riveted or welded.

[0011] In the anti-static device for a computer motherboard interface with a plastic shell as described above, the elastic connecting piece is a flexible body, including an elastic part and a fixed part, the elastic part and the fixed part are integrated and there is a certain opening and closing angle between the two, the elastic part is connected to the beryllium copper spring, and the fixed part is connected to the computer motherboard interface.

[0012] In the anti-static device for a computer motherboard interface with a plastic shell as described above, the elastic part is composed of an inclined piece and a horizontal piece, one end of the inclined piece is connected to the fixed part, and the other end is connected to the horizontal piece, the horizontal piece is used to connect to the beryllium copper spring, and the inclined piece is used to provide buffering when placed under the conductive aluminum block after being connected to the beryllium copper spring and to make the beryllium copper spring tightly pressed against the conductive aluminum block.

[0013] In the above-mentioned anti-static device for computer mainboard interface with a plastic shell, the number of the beryllium copper shrapnel is consistent with the number of the computer mainboard interfaces.

The grooves penetrate to the hollow structure of the beryllium copper shrapnel but do not penetrate the bottom.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] Due to the characteristics of electric current, it always flows in the direction with the lowest impedance. The antistatic device for the computer motherboard interface with a plastic shell of the utility model can greatly improve the antistatic ability of the motherboard interface, especially in the case of medical and other fields requiring contact discharge of 8kv, which can simply and effectively improve the antistatic ability of the product. Especially for the motherboard itself that did not have much antistatic design in the early stage, by adding a conductive aluminum block and a beryllium copper shrapnel between the plastic shell and the computer motherboard interface, and making structural improvements to the conductive aluminum block and the beryllium copper shrapnel, most of the static electricity current is realized to flow to the ground through this device, and only a small part flows to the inside of the motherboard, and the improvement effect is more prominent. In addition, the antistatic device for the computer motherboard interface with a plastic shell of the utility model adopts a conductive aluminum block and a beryllium copper shrapnel, which has a longer service life compared to the ESD or TVS tube of the prior art.
