[0036] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0037] Embodiment 1:
[0038] Attached Figure 1 and 2 The three-dimensional structure diagram and the cross-sectional structure diagram of the high-safety and high-power ignition electrode plug described in this embodiment 1 are respectively shown. Figure 1 and 2As shown, the high-safety and high-power ignition electrode plug described in this embodiment 1 includes an ignition chip 1, an electrode needle 2 and an insulating sleeve 3. The ignition chip 1 is provided with a plurality of resistor patterns 10, and the plurality of resistor patterns 10 are connected in series according to product design requirements to form a high-power heating circuit, and one of the resistor patterns 10 is also used to be coated with ignition powder; the electrode needle 2 is connected to the heating circuit and can connect the heating circuit to an external power source; the insulating sleeve 3 is tightly wrapped around the ignition chip 1 and the electrode needle 2 to protect the ignition chip 1 and the electrode needle 2. It can be understood that when the ignition electrode plug is connected to an external power source through the electrode needle, the heating circuit is powered on to generate heat and instantly generates high-temperature heat to detonate the ignition powder. It has been verified that the heating circuit can generate high-temperature heat of up to 1400°C in a response time of less than 10 microseconds, with good ignition effect and high ignition success rate, which can well meet the market demand of application products, such as: meeting the heat / energy requirements of medium and / or large aircraft for parachute opening.
[0039] The specific structure of the high-safety and high-power ignition electrode plug described in this embodiment 1 is described in detail below.
[0040] First, regarding the ignition chip 1 .
[0041] In this embodiment 1, the ignition chip 1 preferably adopts the following structure: Figures 2 to 4 As shown, the ignition chip 1 is mainly provided with a substrate 11, a plurality of resistor patterns 10, a plurality of connectors 12 and a heat dissipation copper body 13, wherein the substrate 11 is used as the base part of the ignition chip 1, and is adapted to the heating function of the ignition chip 1, improves the structural stability of the ignition chip 1, and improves the installation convenience of the ignition chip 1. The substrate 11 preferably adopts a ceramic composite board or a glass fiber composite board with good thermal conductivity, and is in a flat or flat sheet structure as a whole. It is understandable that the substrate 11 is provided with a front side and a back side arranged opposite to the front side, so as to provide the components such as the resistor pattern 10, the connector 12 and the heat dissipation copper body 13 for setting / molding.
[0042] The plurality of resistor patterns 10 are used as the core heating part of the ignition chip 1. The configuration quantity, shape and resistance value of the resistor patterns 10 are not limited in this embodiment 1 and are determined according to the design requirements of the application product. In particular, the resistance value of the resistor pattern 10 is set based on the technical requirements of the application product (such as a parachute for a low-altitude aircraft, etc.) for ignition heat, detonation current, etc.; Figure 2 and 3The figure shows a situation where the resistor pattern 10 is configured as three and all are rectangular, and the resistance value of the resistor pattern 10 not only meets the ignition heat of the application product, but also meets the requirements of the ignition current of the application product being 1A, 1.5A or 2A; but it is understandable that the present application is not limited to this.
[0043] In addition, the plurality of resistor patterns 10 are formed on the front side of the substrate 11 by electroplating and etching processes. It is understandable that, on the one hand, based on the above electroplating and etching processes, the resistance value of the resistor pattern 10 can be flexibly controllable and has high resistance accuracy. On the basis of meeting the high-power heat demand, the ignition accuracy and safety accuracy of the ignition electrode plug can be greatly improved, and the application product's demand for high safety current can be met; on the other hand, because the plurality of resistor patterns 10 are centrally arranged on the same plane, the thermal focusing effect of the ignition chip 1 can be better, thereby further improving the heating / ignition effect of the ignition chip 1. Supplementary explanation: The above-mentioned central arrangement of the plurality of resistor patterns 10 on the front side of the substrate 11 is only a preferred embodiment of the present application. The present application is not limited to this in actual application. The plurality of resistor patterns 10 can also be distributed on the front and back sides of the substrate 11 according to the technical requirements of the application product (such as: the safety current is 2A and the power is 2W).
[0044] In addition, in order to better achieve the effect of "high-power heat", the resistance pattern 10 is preferably made of nickel-chromium alloy to achieve the characteristics of high resistivity and high heat resistance.
[0045] The plurality of connectors 12 are used as the connection / connection part of the ignition chip 1, that is, the plurality of resistor patterns 10 can be connected in series through the plurality of connectors 12 to form the heating circuit together; based on the arrangement and configuration number of the plurality of resistor patterns 10, the plurality of connectors 12 are also arranged on the front side of the substrate 11 (of course, when the plurality of resistor patterns 10 are distributed on both the front and back sides of the substrate 11, the plurality of connectors 12 can also be distributed on both the front and back sides of the substrate 11), and the configuration number of the connectors 12 is one more than the configuration number of the resistor patterns 10, and the attached Figure 2 and 3The case where the connector 12 is configured as four is shown in the figure. At that time, the four connectors 12 and the three resistor patterns 10 are sequentially connected in series to form the heating circuit together, and the resistor pattern 10 located in the middle is also used to be coated with ignition powder. In addition, this embodiment 1 does not impose any restrictions on the shape of the connector 12, and the design is specifically based on the shape and size of the front side of the substrate 11, and the shape, size and layout of the resistor pattern 10. In addition, regarding the specific manner in which the connector 12 is arranged on the front side of the substrate 11, a variety of methods can be adopted according to product design requirements, such as: when the connector 12 adopts a copper foil structure, it can be adhered and fixed on the front side of the substrate 11; and when the connector 12 adopts a copper layer pattern structure, it can be formed on the front side of the substrate 11 through an electroplating process.
[0046] The heat dissipation copper body 13 is used as the heat dissipation part of the ignition chip 1, and is fixedly arranged on the back side of the substrate 11. As for the specific manner in which the heat dissipation copper body 13 is arranged on the back side of the substrate 11, reference can be made to the connector 12, for example: when the heat dissipation copper body 13 adopts a copper foil structure, it can be attached and fixed on the back side of the substrate 11; and when the heat dissipation copper body 13 adopts a copper layer pattern structure, it can be arranged on the back side of the substrate 11 through an electroplating process.
[0047] Next, let's discuss the electrode needle 2 and the insulating sleeve 3 .
[0048] In this embodiment 1, based on the structure of the ignition chip 1, the electrode needle 2 is configured as two, and is respectively welded and fixedly connected to two of the connectors 12. Furthermore, ① the electrode needle 2 can preferably adopt an L-shaped structure, which is convenient for welding and fixing with the connector 12, and has good connection firmness. ② A soldering pad 14 (made of copper) connected to the connector 12 is also provided on the back of the substrate 11, and the soldering pad 14 is also welded and fixedly connected to the electrode needle 2, further improving the installation stability, electrical connectivity, etc. of the electrode needle 2.
[0049] The insulating sleeve 3 is made of high temperature resistant material and is tightly wrapped around the ignition chip 1 and the electrode needle 2 through injection molding process to protect the ignition chip 1 and the electrode needle 2; Figure 1 and 2 It can be seen that the resistance pattern 10 for being covered by the ignition powder and one end of the two electrode needles 2 are both extended out of the insulating sleeve 3 .
[0050] Finally, this embodiment 1 also briefly describes the method for manufacturing the high-safety and high-power ignition electrode plug.

[0054] Note: The above-mentioned vacuum coating, chemical copper deposition, electroplating, anti-corrosion photosensitive film coating, exposure, development, etching and film stripping processes are all conventional technical means in the field of circuit board production, so they will not be described in detail here.
[0055] S3: Provide a plurality of connectors 12 each of which adopts a copper foil structure and at least one heat dissipation copper body 13 also of a copper foil structure, and adhere and fix the plurality of connectors 12 to the front side of the substrate 11 through a lamination process, and adhere and fix at least one heat dissipation copper body 13 to the back side of the substrate 11, and at the same time, the plurality of connectors 12 are also contacted and welded to the plurality of resistor patterns 10 according to the electrical requirements of the product, so as to obtain the ignition chip 1.
[0056] Note: The above lamination process is also a conventional technical means in the field of circuit board production, so it will not be described in detail here.
[0057] S4: providing two electrode needles 2, and welding and fixing the two electrode needles 2 to the two connectors 12 respectively; then an intermediate is obtained.

It can be understood that the configuration quantity, shape, resistance value, etc. of the resistor pattern 10 and the connector 12 are not limited in the second embodiment and are determined according to product design requirements.
[0063] In addition, based on the heating circuit structure described in the second embodiment, the S-shaped resistor pattern 10 is used to be covered by the ignition charge.
