Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrostatic protection technology, and in particular to an electrostatic protection component. Background Technology
[0002] In current applications, static electricity is easily generated and accumulated when objects of various materials rub against each other. When these objects come into contact with electronic products, static electricity is generated. Without proper protection, this can lead to anything from product reset and restart to irreversible damage. Therefore, static electricity protection is a crucial part of the product design process.
[0003] The electrostatic discharge (ESD) protection design of a product consists of numerous components. At the motherboard level, ESD protection typically employs various ESD protection devices in conjunction with a discharge circuit. While these devices effectively discharge ESD interference under operating conditions, they also increase bill of materials (BOM) costs and production costs. In cost-sensitive products, the use of ESD protection devices further exacerbates cost pressures. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an electrostatic protection component that achieves electrostatic protection while reducing additional components or lowering production costs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] An electrostatic discharge protection component includes an insulating base and a first conductive contact and a second conductive contact located on the insulating base.
[0007] The first conductive contact has a first acute-angled side, and the second conductive contact has a second acute-angled side.
[0008] The tip of the first acute angle side is positioned opposite to the tip of the second acute angle side;
[0009] The first conductive contact is used to connect to the target protection line, and the second conductive contact is used to connect to the electrical ground.
[0010] Furthermore, both the first conductive contact and the second conductive contact are pads.
[0011] Furthermore, the pad is a triangular pad.
[0012] Furthermore, the insulating base is a printed circuit board.
[0013] Furthermore, the angle range of the first acute angle side is the same as the angle range of the second acute angle side.
[0014] Furthermore, the angle of the first acute angle side ranges from 50° to 70°.
[0015] Furthermore, the distance between the tip of the first acute angle and the tip of the second acute angle ranges from 3 mil to 5 mil.
[0016] The beneficial effects of this utility model are as follows: It provides an electrostatic discharge (ESD) protection component, in which a first conductive contact and a second conductive contact are provided on an insulating base, which are respectively connected to the target protection circuit and the electrical ground of the electronic product; when static electricity is conducted to the target protection circuit, due to the presence of the first acute angle side of the first conductive contact, the static electricity will be guided to the tip of the first acute angle side, thereby ionizing the air at this point and realizing arc discharge. Since the tip of the first acute angle side is opposite to the tip of the second acute angle side, the static electricity will be conducted to the second conductive contact, that is, into the electrical ground, thereby preventing the static electricity from continuing to propagate on the target protection circuit, realizing ESD protection without the need for existing protective devices, and reducing the production cost of electronic products.

[0020] 1. Insulating base; 2. First conductive contact; 3. Second conductive contact; 4. First acute angle side; 5. Second acute angle side; 6. Target protection line; 7. Electrical ground. Detailed Implementation
[0021] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0022] Please refer to Figure 1 and Figure 2 An electrostatic protection component includes an insulating base 1 and a first conductive contact 2 and a second conductive contact 3 located on the insulating base 1.
[0023] The first conductive contact 2 has a first acute-angled side 4, and the second conductive contact 3 has a second acute-angled side 5.
[0024] The tip of the first acute angle side 4 is positioned opposite to the tip of the second acute angle side 5;
[0025] The first conductive contact 2 is used to connect to the target protection line 6, and the second conductive contact 3 is used to connect to the electrical ground 7.
[0026] As can be seen from the above description, the beneficial effects of this utility model are as follows: A first conductive contact 2 and a second conductive contact 3 are provided on the insulating base 1, which are respectively connected to the target protection line 6 and the electrical ground 7 of the electronic product; when static electricity is conducted to the target protection line 6, due to the presence of the first acute angle side 4 of the first conductive contact 2, the static electricity will be guided to the tip of the first acute angle side 4, thereby ionizing the air at this point and realizing arc discharge. Since the tip of the first acute angle side 4 is opposite to the tip of the second acute angle side 5, the static electricity will be conducted to the second conductive contact 3, that is, into the electrical ground 7, thereby preventing the static electricity from continuing to be transmitted on the target protection line 6, realizing electrostatic protection without the need for the existing protective devices, and reducing the production cost of electronic products.
[0027] Furthermore, the pad is a triangular pad.
[0028] As can be seen from the above description, the pad is a triangular pad. The sharp corners of the triangle help to guide static electricity to the tip of the sharp corner and to receive static electricity at the electrical ground 7 position.
[0029] Furthermore, the insulating base 1 is a printed circuit board.
[0030] As can be seen from the above description, printed circuit boards are a commonly used basic component in the electronics field. Mature printed circuit technology can be used to easily integrate circuit elements such as the first conductive contact 2 and the second conductive contact 3 onto them, which is conducive to realizing miniaturized and integrated electrostatic protection design and adapting to the compact space layout requirements of modern electronic products.
[0031] Furthermore, the angle range of the first acute angle side 4 is the same as the angle range of the second acute angle side 5.
[0032] Furthermore, the angle of the first acute-angled side 4 ranges from 50° to 70°.
[0033] As can be seen from the above description, if the angle of the first acute angle side 4 and the second acute angle side 5 is too large, although it can provide a smaller release impedance, it will affect the spike effect of the arc discharge; if the angle of the first acute angle side 4 and the second acute angle side 5 is too small, the release impedance will increase, which is not conducive to the rapid release of external static electricity. Therefore, the angle of the first acute angle side 4 and the second acute angle side 5 is set to a range of 50° to 70°, preferably 60°, to ensure that the external static electricity is rapidly discharged and conducted at the tip of the first acute angle side 4, thereby improving the stability and reliability of static electricity release.
[0034] Furthermore, both the first conductive contact 2 and the second conductive contact 3 are pads.
[0035] As can be seen from the above description, the target protection line 6 and the electrical ground 7 are reliably connected to the corresponding pads by the welding process, which reduces the assembly difficulty, ensures that the target protection line 6 and the electrical ground 7 are firmly connected to the contact, and reduces the problem of unstable electrical performance caused by loose connection.
[0036] Furthermore, the distance between the tip of the first acute angle side 4 and the tip of the second acute angle side 5 ranges from 3 mil to 5 mil.
[0037] As can be seen from the above description, the smaller the tip spacing is theoretically, the better. However, the spacing is limited by the level amplitude of the protected signal. If the spacing is too small, it may cause the normal signal strength to trigger arc discharge and short circuit to ground. On the one hand, it is limited by the printed circuit board processing process, that is, to meet the basic requirements of printed circuit board processing and manufacturing, and to avoid the normal signal of the target protection line 6 triggering arc discharge and short circuit to ground.
[0038] Please refer to Figure 1 and Figure 2 Embodiment 1 of this utility model is as follows:
[0039] An electrostatic discharge (ESD) protection component includes an insulating base 1 and a first conductive contact 2 and a second conductive contact 3 located on the insulating base 1; the first conductive contact 2 has a first acute-angled side 4, and the second conductive contact 3 has a second acute-angled side 5.
[0040] The tip of the first acute-angled side 4 is positioned opposite to the tip of the second acute-angled side 5; the first conductive contact 2 is used to connect to the target protection line 6, and the second conductive contact 3 is used to connect to the electrical ground 7. As an optional design, the distance between the tips of the first acute-angled side 4 and the second acute-angled side 5 ranges from 3 mil to 5 mil, preferably 4 mil.
[0041] In this embodiment, the angle of the first acute angle side 4 ranges from 50° to 70°, preferably 60°. The angle of the second acute angle side 5 also ranges from 50° to 70°, preferably 60°.
[0042] Combination Figure 1 and Figure 2 As shown, the protection process of an electrostatic discharge (ESD) protection component is as follows:
[0043] When the target protection line 6 is affected by external static electricity, the high voltage caused by the static electricity (the intensity is generally greater than the normal signal of the target protection line 6) will be guided by the first conductive contact 2 to the tip of the first acute angle side 4, thereby causing an air click and generating an electric arc discharge. The second acute angle side 5 of the second conductive contact 3 receives the discharge arc and conducts the static electricity to the electrical ground 7, thus completing the static discharge.
[0044] In this embodiment, as Figure 1As shown, both the first conductive contact 2 and the second conductive contact 3 are triangular pads; the insulating base 1 is a printed circuit board. Both the first conductive contact 2 and the second conductive contact 3 have an open window design, without being covered with solder resist ink, to ensure their contact with air.
[0045] In summary, this utility model provides an electrostatic discharge (ESD) protection component. A first conductive contact and a second conductive contact are provided on an insulating base, which are respectively connected to the target protection circuit and the electrical ground of the electronic product. When static electricity is conducted to the target protection circuit, due to the presence of the first acute angle side of the first conductive contact, the static electricity is guided to the tip of the first acute angle side, thereby ionizing the air at that point and achieving arc discharge. Since the tips of the first and second acute angle sides are opposite each other, the static electricity is conducted to the second conductive contact, i.e., into the electrical ground. This prevents the static electricity from continuing to propagate along the target protection circuit, completing the electrostatic discharge without the need for existing protective devices, thus reducing the production cost of electronic products.
[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
