Description
TECHNICAL FIELD
[0001] The application relates to the technical field of terminals, in particular to a welded terminal structure applied to multilayer glass. BACKGROUND
[0002] Terminals are common connection technologies in electrical and electronic engineering, used to achieve reliable electrical connection between wires and devices, circuit boards or other wires. Most of the windshields on the market are usually laminated glass, and most of them have heating functions, which are designed to quickly remove frost or fog on the windshield. This requires the use of conductive materials (usually fine metal wires or transparent conductive films), and these heating elements need to be connected to the electrical system of the vehicle through terminals.
[0003] In related technologies, the terminals on the automobile glass are usually fixed by welding. However, in the welding process, the outer wall of the terminal directly contacts the surface of the glass, and the high temperature generated during the welding process will cause the terminal and the glass to expand. The expansion coefficients of the terminal and the glass are different, and after cooling, the terminal and the glass will shrink and generate stress. Since the terminal is made of metal rigid material, the stress cannot be dispersed in time, and eventually it is easy to cause the glass to break after welding, thereby reducing the yield. UTILITY MODEL CONTENT
[0004] The application provides a welded terminal structure applied to multilayer glass, which can prevent the soldering surface of the terminal from directly contacting the surface of the glass, effectively improve the situation that the glass breaks after welding, and improve the welding yield.
[0005] The welded terminal structure applied to multilayer glass provided by the application adopts the following technical scheme:
[0006] A welded terminal structure applied to multilayer glass comprises a body, a soldering surface of the body faces the glass, a lifting portion is integrally formed on the body, an inclined surface is formed on the side of the lifting portion facing the glass, the inclined surface is inclined upward along the direction away from the soldering surface, a gap is formed between the inclined surface and the surface of the glass for the insertion of a tool clamp, and the tool clamp is used to elevate the body.
[0007] Preferably, the lifting portions are symmetrically arranged on both sides of the body.
[0008] Preferably, a supporting portion is integrally formed at the end of the lifting portion away from the body, a supporting surface is formed on the side of the supporting portion facing the glass, and the supporting surface is parallel to the soldering surface.
[0009] Preferably, a connecting part is arranged between the adjacent bodies, and the connecting part is integrally formed with the end of the respective opposite upturned part at both ends thereof; and a spacing groove is formed between the side of the connecting part facing the glass and the surface of the glass.
[0010] Preferably, a solder layer is arranged on the solder surface.
[0011] In summary, the present application has at least one of the following beneficial technical effects:
[0012] By inserting the tool clamp into the accommodation groove, the body is elevated by the tool clamp to ensure that the solder surface does not directly contact the glass surface. In addition, the tool clamp can also fix the body to prevent the body from moving during welding, thereby improving the stability of the body. The stress generated by the body and the glass during welding can be quickly dispersed without contact points, thereby effectively improving the situation that the glass breaks after welding is completed, and improving the welding yield.
[0013] The connecting part is used to realize the sequential connection of multiple bodies, and the solder terminal will form multiple solder surfaces at this time. For the solder terminal with multiple solder surfaces, the scheme of the present application can also effectively improve the situation that the glass breaks after welding is completed, thereby improving the welding yield.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.
[0020] The embodiment of the present application discloses a solder terminal structure applied to a multi-layer glass.
[0021] Embodiment one: refer toFigure 1 The solder terminal structure applied to the multi-layer glass comprises a body 1 made of metal conductive material, a soldering surface 10 is formed on the bottom of the body 1 and faces the glass surface, a soldering layer 100 is arranged on the soldering surface 10, and the body 1 is soldered and fixed on the glass through the soldering layer 100.
[0022] As shown in Figure 1 , two upturned portions 2 are integrally formed on the body 1, and the upturned portions 2 are symmetrically arranged on the left and right sides of the body 1. An inclined surface 20 is formed on the side of the upturned portion 2 facing the glass, the inclined surface 20 is obliquely inclined away from the soldering surface 10, and a gap slot 3 is formed between the inclined surface 20 and the glass surface for the insertion of a tool clamp.
[0023] Before the body 1 is soldered and fixed, the tool clamp is inserted into the gap slot 3, and the body 1 is elevated by the tool clamp to ensure that the soldering surface 10 does not directly contact the glass surface. In addition, the tool clamp can also fix the body 1 to prevent the body 1 from moving during soldering, thereby improving the stability of the body 1. The stress generated during soldering of the body 1 and the glass without contact points can be quickly dispersed without contact points, thereby effectively improving the situation that the glass breaks after soldering is completed, and improving the soldering yield.
[0024] Example Two: As shown in Figure 2 , unlike the structure of Example One, a support portion 4 is integrally formed at the end of the upturned portion 2 away from the body 1, a support surface 40 is formed on the side of the support portion 4 facing the glass, and the support surface 40 is parallel to the soldering surface 10. The support surface 40 further increases the contact area of the tool clamp with the body 1, and when the tool clamp is inserted into the gap slot 3, the tool clamp can be in close contact with the support surface 40, thereby further improving the clamping and fixing effect of the tool clamp on the body 1 and ensuring the stability of the body 1 during soldering.
[0025] Example Three: As shown in Figure 3 , unlike the structure of Example One, a connecting portion 5 is arranged between adjacent bodies 1, and the connecting portion 5 is used to sequentially connect and fix the bodies 1. The left and right ends of the connecting portion 5 are integrally formed with the respective opposite ends of the upturned portions 2, and a spacing slot 50 is formed between the side of the connecting portion 5 facing the glass and the glass surface. The spacing slot 50 is arranged so that the bottom of the connecting portion 5 does not directly contact the glass surface. The connecting portion 5 is used to sequentially connect multiple bodies 1, and at this time the soldering terminal will form multiple soldering surfaces 10. For the soldering terminal with multiple soldering surfaces 10, the scheme of the present application can also effectively improve the situation that the glass breaks after soldering is completed, thereby improving the soldering yield.
[0026] Embodiment four: as shown, unlike the structure of embodiment two, a connecting part 5 is arranged between adjacent bodies 1, and the connecting part 5 is used to sequentially connect and fix the bodies 1. The left and right ends of the connecting part 5 are integrally formed with the end of the respective opposite raised part 2, and a spacing groove 50 is formed between the side of the connecting part 5 facing the glass and the surface of the glass. The spacing groove 50 is arranged so that the bottom of the connecting part 5 does not directly contact the surface of the glass. The connecting part 5 is used to sequentially connect multiple bodies 1, and at this time the soldering terminal will form multiple soldering surfaces 10. For the soldering terminal with multiple soldering surfaces 10, the scheme of the present application can also effectively improve the situation that the glass breaks after the soldering is completed, and the soldering yield is improved. Figure 4
[0027] The implementation principle is that by inserting the tool clamp into the accommodation groove 3, the body 1 is elevated by means of the tool clamp to ensure that the soldering surface 10 does not directly contact the surface of the glass, and in addition the tool clamp can also fix the body 1 to prevent the body 1 from moving during soldering, thereby improving the stability of the body 1. In the absence of contact points, the stress generated by the body 1 and the glass during soldering can be quickly dispersed in the absence of contact points, thereby effectively improving the situation that the glass breaks after the soldering is completed, and the soldering yield is improved. After the soldering is completed, the tool clamp is removed from the accommodation groove 3 to complete the soldering work.
[0028] The connecting part 5 is used to sequentially connect multiple bodies 1, and at this time the soldering terminal will form multiple soldering surfaces 10. For the soldering terminal with multiple soldering surfaces 10, the scheme of the present application can also effectively improve the situation that the glass breaks after the soldering is completed, and the soldering yield is improved.
[0029] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made in accordance with the structure, shape, principle of the present application should be covered within the protection scope of the present application.
