M249199 _Case No.92221030__Year Month and Day You Do Not _ IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is a kind of contact structure, especially a contact structure between a cold cathode tube and a high-voltage conductor. [Previous technology] Generally, because of the simple structure of the cold cathode tube, it can be a thinner fluorescent tube than the hot cathode tube. Therefore, the cold cathode tube is usually applied to electronic products such as LCD screens or scanners. To reduce the volume of these electronic products. And because the cold cathode tube needs to be driven by high voltage, the core of the cold cathode tube will be connected with a high-voltage wire, and the connection between the cold cathode tube and the south pressure wire is fresh, such as The first picture, the second picture, and the attachment 1 show 'these are the structure of the contact 14 of the cold cathode tube 10 and the high voltage wire 12 after welding, the cold cathode tube 11 and the high voltage wire 12 respectively. An enlarged view of the structure of the welding contact 14 and a solid diagram of the welding contact between the lamp core 11 and the south pressure wire 12 of the cold cathode tube 10. It can be seen from the figure that this welding method is prone to problems such as empty welding and inaccurate welding. The reasons include the lamp core. The surface treatment of u and high-voltage wire 12 is poor, etc., and when the cold-cathode tube 10 is driven by high voltage, high temperature will be generated at the junction between the lamp core of the cold-cathode tube 10 and the high-voltage wire 12, and the welding is not sure at this time. Could the solder be affected by high temperature and heat? This reduces the reliability of product quality. In addition, the resistance 14 and poor conductivity of the contact 14 generated by the solder and the y-connector will also affect the quality of the cold pipe 10 to a certain extent. κ In addition, most of the current manual welding methods are used to weld the core of the cold cathode tube. In addition to the unstable quality and high production cost, it is also difficult to improve the MZ4yiyy case number 9222. 0 If it is modified, it will directly or indirectly pollute Overall 9. Creation instructions (2) Affect the health and environment of the welding operator. In view of this, we have created the contact structure of μ cold cathode tubes to understand the technical difficulties. We propose that-^ M effectively overcomes the lack of knowledge. [New content] The main purpose of the V3 composition creation is to use the welding technology to reduce the melting junction by using the cold junction of the cold cathode tube. The second purpose is to provide a high-voltage wire connection = the purpose of creation. A kind of cold cathode tube contact junction is used to form a stable welded joint, so as to avoid the lamp core and high-voltage wire of the cold cathode tube? Problems The other purpose of this creation is to provide a contact structure for cold cathode tubes to avoid the problem of environmental pollution caused by the conventional welding method. Another purpose of this creation is to provide a contact structure of a cold cathode tube, which uses mechanical equipment to perform welding operations, thereby increasing the output and reducing the cost of mass production. According to this creation, the contact structure of a cold cathode tube is formed by welding the core of a cold cathode tube and a high-voltage wire. This welding technology includes high-voltage discharge welding technology, laser welding technology, gas welding technology, and ultrasonic welding Technology and high-frequency fusion technology, etc. 'Using fusion technology can improve the joint between the core of the cold danger tube and the high-voltage wire, thereby enhancing the stability of the junction and the junction between the core of the cold-cathode tube and the high-voltage wire. Resistors for better conductivity. The description of the specific embodiment below is used to compare the attached round form.

M249199 ---- Case No.92221030 Afternoon Moon Day Chromium A__ IV. Creation Instructions (3) It is easier to understand the purpose, technical content, features and effects of this creation. [Embodiment] The present invention is a contact structure of a cold cathode tube (Cold Cathode Fluorescent Lamp), which uses a welding technology to join the core of the cold cathode tube with a high-voltage wire, thereby enhancing the bonding between the two. Strength, and reduce the resistance of the contact structure, thereby improving the conduction efficiency of the contact.

As shown in the third figure, it is a schematic diagram of the embodiment of this creation. As can be seen from the figure, a cold cathode tube 20 has a lamp core 21 which is joined with a high-voltage wire 22, and the high-voltage wire 22 is covered with an insulating layer. 23, and only a part of the conductor is exposed to be connected to the core 21 of the cold cathode tube 20, and the structure of the contact 23 of the cold cathode tube 20 and the high-voltage wire 22 is shown in the fourth figure and the annex II, respectively. As shown in the figure, it can be clearly found that the core 21 and the high-voltage wire 22 of the cold cathode tube 20 are directly fused instead of being welded together through solder. Therefore, the contact 23 does not desolder or fall off due to factors such as high temperature and high heat. That is, by means of fusion processing, the stability of the connection between the lamp core 21 and the high-voltage wire 22 of the cold cathode tube 20 can be greatly improved, and the reliability of the cold cathode tube 20 in use can be indirectly improved.

Refer to the fifth figure, which is a schematic diagram of the fusion of the cold cathode tube 20 lamp core 21 and the high-voltage wire 22 by using the discharge welding technology. From the figure, it can be seen that the cold cathode tube 20 has a lamp core 21 and a high-voltage wire 22 in A welding device is gradually approached and positioned under the conveyance. At this time, a discharge head 24 will release an arc 26 to the intersection of the lamp core 21 and the high-voltage wire 22 of the cold cathode tube 20, and the energy contained in this arc 26 will be cooled by the cold cathode. Tube 20 sucked by lamp core 21 and high-voltage wire 22

Fourth, the creative instructions (4) to close, so that part of the cold cathode tube 20 lamp core 21 and part of the high-voltage wire 22 in a molten state, at this time the molten state of the lamp core 21 and the high-voltage wire 22 will be fused to each other 'and the discharge head 24 will At this time, the arc release is stopped, and after the cold cathode tube 20 and the high voltage lead 22 are cooled and solidified, the cold cathode tube contact structure shown in the fourth figure and the second attachment can be obtained. In addition, the cold cathode tube contact structure of this creation can also be achieved by other welding technologies, such as laser welding, gas welding, ultrasonic welding, high frequency welding, or composite welding technologies composed of different welding technologies. The techniques are customary techniques and are not the focus of this creation, so they are not described here. The material of the cold-cathode tube lamp core and the high-voltage wire in this creation can be selected from the same material or different materials. When the materials of the two are different, the alloy of the cold-cathode tube lamp and the high-voltage wire will form a solid connection after welding. And from the above, 'this creation uses welding technology to fuse cold cathode tubes and high-voltage wires together. This welding technology can be discharge welding, laser welding, gas welding, ultrasonic welding, or high-frequency welding, etc. In addition to reducing the contact resistance between the cold-cathode tube and the high-voltage wire, in order to improve the electrical conductivity, it can also avoid the environmental pollution problems caused by the conventional welding process. Furthermore, this creation uses welding equipment to perform processing operations.
