[0030] Referring to Figure 1The windscreen plug-in part comprises a plug-in part body 1, a rubber sleeve 2 arranged on the side of the plug-in part body 1 facing the glass 10, and a wire 3 electrically connected with the plug-in part body 1, and there is a gap between the plug-in part body 1 and the glass 10 under the action of the rubber sleeve 2, and the side of the plug-in part body 1 facing the glass 10 is provided with solder 4, the solder 4 is adjacent to the rubber sleeve 2, and the solder 4 fills in the gap after being melted.
[0031] Through the implementation of the above technical scheme, when the windscreen plug-in part is installed on the glass 10, the windscreen plug-in part is first placed on the surface of the glass 10, and then the solder 4 is melted through heating to realize the welding between the windscreen plug-in part and the glass 10.
[0032] During the installation of the windscreen plug-in part, the rubber sleeve 2 contacts the surface of the glass 10 and supports the plug-in part body 1, and during the subsequent heating process, the solder 4 is slowly melted as the temperature rises, the melted solder 4 is in a liquid state and flows, and the rubber sleeve 2 is arranged between the windscreen and the plug-in part body 1, and can always support the plug-in part body 1 during the melting of the solder 4, so that the plug-in part body 1 and the glass 10 maintain a distance, thereby avoiding that the plug-in part body 1 extrudes the solder 4 in a liquid state under the action of gravity and finally extrudes the solder 4 to fall on the surface of the glass 10, thereby avoiding that the plug-in part body 1 contacts the surface of the glass 10 and causes the glass 10 to crack.
[0033] The surface of the glass 10 is coated with a silver paste coating 6, and the windscreen plug-in part is welded on the silver paste coating 6. The plug-in part body 1 is welded with the silver paste coating 6 of the glass 10 through the solder 4, so that the windscreen plug-in part and the silver paste coating 6 on the glass are electrically connected, and then the wire electrically connected with the plug-in part body 1 can be electrically connected with the vehicle battery.
[0034] Preferably, the rubber sleeve 2 is arranged at least two, and the two rubber sleeves 2 are arranged at the two ends of the plug-in part body 1.
[0035] The two rubber sleeves 2 arranged at the two ends of the plug-in part body 1 can effectively support the plug-in part body 1. Moreover, the rubber sleeves 2 at the two ends can also limit the solder 4 in the middle, and the melted solder 4 can only flow in the width direction of the plug-in part body 1 during the flowing process, thereby improving the reliability of the welding between the windscreen plug-in part and the glass 10.
[0036] In this embodiment, in order to facilitate the fixation of the rubber sleeve 2 and the plug-in part body 1, the rubber sleeve 2 can be arranged in a cylindrical shape, and the rubber sleeve 2 in a cylindrical shape is arranged on the end of the plug-in part body 1 to realize the reliable fixation of the rubber sleeve 2 and the plug-in part body 1.
[0037] In another embodiment, the rubber sleeve 2 is arranged along the outer edge of the connector body 1, and the rubber sleeve 2 and the connector body 1 enclose an open space, and the solder 4 is arranged in the space. In order to facilitate the flow of the solder 4 during the soldering process, the rubber sleeve 2 can be arranged as a hollow structure.
[0038] In this embodiment, preferably, the thickness of the surface of the rubber sleeve 2 facing the glass 10 is 0.1-1mm.
[0039] In order to ensure the reliable support of the rubber sleeve 2 to the connector body 1, the thickness of the rubber sleeve 2 is arranged to be 0.1-1mm.
[0040] The thickness of the rubber sleeve 2 is not less than 0.1mm, which can effectively avoid the problem of the contact between the connector body 1 and the glass 10. When the thickness of the rubber sleeve 2 is arranged to be not less than 0.1mm, on the one hand, the thickness of the solder 4 after the soldering is completed can be ensured, thereby ensuring the reliability of the electrical connection between the connector of the windshield glass and the silver paste coating 6; on the other hand, the gap of not less than 0.1mm between the connector body 1 and the glass 10 can be arranged through the rubber sleeve 2, which can effectively overcome the flatness problem of the surface of the connector body 1 facing the glass 10, so that any point on the surface of the connector body 1 facing the glass 10 will not contact the glass 10.
[0041] The thickness of the rubber sleeve 2 is not more than 1mm, which can effectively avoid the overuse of the solder 4. Because the gap between the connector body 1 and the surface of the glass 10 needs to be filled by the solder 4, when the thickness of the rubber sleeve 2 is arranged to be more, more solder 4 needs to be filled, and then the amount of the solder 4 used is increased, which causes the increase of the cost.
[0042] Preferably, the thickness of the rubber sleeve 2 is arranged to be 0.3mm, which can balance the reliability of the soldering and also can achieve the effect of saving the cost to the greatest extent.
[0043] In this embodiment, preferably, the width of the solder 4 is not more than the width of the connector body 1.
[0044] In order to better control the amount of the solder 4 used, the width of the solder 4 is arranged to be not more than the width of the connector body 1, and when the solder 4 is melted, the width direction of the connector body 1 can be completely covered through the flow.
[0045] In this embodiment, preferably, the length of the solder 4 is not less than 2mm.
[0046] In order to facilitate the operation of the staff, the length of the solder 4 is not less than 2mm.
[0047] In one embodiment, the plug-in body 1 can be fixedly provided with a solder 4. If the length of the plug-in body 1 is relatively long, the length of the solder 4 can be appropriately increased so that, after the solder 4 is heated and melted, it can completely fill the gap between the plug-in and the glass 10 along the length direction.
[0048] In another embodiment, the plug-in body 1 can be fixedly provided with a plurality of solders 4 along the length direction. By reasonably arranging the interval of the solders 4, the solders 4 can completely fill the gap between the plug-in and the glass 10 along the length direction during the process of flowing around after being melted.
[0049] In this embodiment, preferably, the wire 3 is wrapped with an insulating sleeve.
[0050] The wire 3 wrapped with an insulating sleeve can avoid the contact between the wire 3 and the glass 10, thereby avoiding the problem of causing the glass 10 to be cracked.
[0051] Reference Figures 2-3 A heating structure of a windshield glass, which comprises a heating resistance wire arranged on the glass 10 and plug-ins of the windshield glass welded to both ends of the resistance wire, and wires 3 of the two plug-ins of the windshield glass are respectively connected to the positive and negative poles of the automobile power supply.
[0052] The wires 3 of the two plug-ins 8 of the windshield glass are respectively connected to the positive and negative poles of the automobile power supply. When the glass 10 needs to be heated, the automobile power supply provides electric energy to the heating resistance wire through the two plug-ins 8 of the windshield glass, and makes it generate heat. The heat energy generated by the heating resistance wire is used to heat the glass 10.
[0053] In this embodiment, preferably, the heating resistance wire comprises a tungsten wire 7 and a silver paste coating 6 arranged at both ends of the tungsten wire 7, and the silver paste coating 6 is electrically connected to the tungsten wire 7.
[0054] The silver paste coatings 6 arranged at both ends of the tungsten wire 7 are respectively electrically connected to the two plug-ins 8, and are respectively connected to the positive and negative poles of the power supply through the two plug-ins 8. When the power supply is turned on, the current passes through the tungsten wire 7, and according to P=I 2 R, the tungsten wire 7 will start to heat.
[0055] If there is only one tungsten wire 7, this tungsten wire 7 can realize the heating function of the glass 10 around the region where it is located.
[0056] If there are a plurality of tungsten wires 7, the plurality of tungsten wires 7 are connected in parallel, and these parallel tungsten wires 7 respectively heat the glass 10 around the region where they are located. As shown in Figure 2 If these parallel tungsten wires 7 cover the entire surface of the glass 10, the heating resistance wire can realize the heating of the entire surface of the glass 10.
[0057] When multiple tungsten wires 7 are arranged in parallel, the silver paste coating 6 is located at both ends of the tungsten wires 7, such as... Figure 2 As shown, the distance between the two silver paste coatings 6 will be relatively far. In order to save the use of wires 3 and at the same time take into account the appearance requirements of the whole vehicle, the connectors of the two windshields can be set as close as possible to the bottom of the glass.
[0058] In this embodiment, preferably, the two ends of the tungsten wire 7 are as close as possible, and the distance between the silver paste coatings 6 at the two ends is not less than 5 mm.
[0059] If only one tungsten wire 7 is used, then it is advisable to bend and twist the tungsten wire 7 in a roundabout way, so as to avoid short circuits and bring the two ends of the tungsten wire 7 as close as possible, so that the connectors of the two windshields can also be as close as possible, which facilitates the wiring harness layout of the whole vehicle.
[0060] The silver paste coatings 6 at both ends of the tungsten wire 7 also need to maintain a gap of not less than 5mm to avoid positional errors during the printing of the silver paste coatings 6, which could cause a short circuit between the two silver paste coatings 6.
[0061] In this embodiment, preferably, the ends of the wires 3 of the two windshield connectors away from the connector body 1 converge and are connected to a quick-connect connector 9.
[0062] like Figure 4 As shown, when the connectors of the two windshields are very close together, the two wires 3 can be joined together to effectively secure them. The wires 3 need to be wrapped with a retaining sleeve. After the two wires 3 are joined together, they are secured side-by-side by the retaining sleeve and finally connected to the quick-connect connector 9. One end of the vehicle's wiring harness is connected to the vehicle's power supply, and the other end is plugged into the quick-connect connector 9, thus connecting the windshield heating structure to the power supply, which is very convenient.
[0063] In this embodiment, preferably, multiple tungsten wires 7 are provided, and the multiple tungsten wires 7 are arranged in parallel.
[0064] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0065] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0066] In addition, various different embodiments of the present application can be combined arbitrarily, as long as they do not violate the spirit of the present application, and should be considered as disclosed by the present application.
