The welding plate can be understood as a welding position of a charging connector, the welding plate is used for transmitting electric power, such as voltage and the like, to the charging connector, the welding plate can be a flexible circuit board, and can also be a circuit board made of a certain rigid material, and the welding method comprises the following steps:
and step S10, enabling the positions of the welding plate and the charging connector to be close to each other, and enabling a welding gap to be formed between the welding plate and the charging connector.
Specifically, the welding plate can be fixed, the charging connector is moved close to the welding plate, the charging connector can be fixed, the welding plate is moved close to the charging connector, and then the welding plate and the charging connector are close to each other. For example, the charging connector is fixed by a fixing device, and a welding worker directly moves the welding plate or moves the welding plate to the charging connector by a mobile device to start welding operation. When the distance between the welding plate and the charging connector is fixed, the welding plate and the charging connector are fixed, precision deviation cannot occur during welding, and the distance between the welding plate and the charging connector can effectively guarantee that soldering tin is connected with the welding plate and the charging connector. The welding distance between the welding plate and the charging connector can be adjusted according to the design and use requirements. For example, the width of the welding gap is 0.05mm-0.2mm, and when the width of the welding gap is 0.05mm, the positions of the charging connector and the welding plate are tighter, so that the soldering tin can be effectively ensured to be in welding connection with the charging connector and the welding plate. When the width of the welding gap is 0.2mm, the tin soldering is easy to spray, in other words, enough space is provided for tin soldering operation, and the smooth operation of the tin soldering operation is ensured. The width of welding gap still can be for 0.1mm, so can guarantee the welded connection of welding plate and the joint that charges, can also provide sufficient working space and carry out the operation of tin spraying.
In step S20, the molten solder is sprayed to the position of the welding gap.
In the related art, the solder is usually pre-welded to the welding plate and then welded by melting the solder. In step S20, it can be seen that, at the position of the welding gap between the welding plate and the charging connector, the molten solder is directly sprayed to the position of the welding point, and the welding plate and the charging connector are welded together through air-drying cooling or natural cooling.

Meanwhile, the material of the supporting member may be light weight and low processing cost, such as abs (acrylonitrile Butadiene styrene) plastic, i.e. acrylonitrile-Butadiene-styrene copolymer, or Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and Polystyrene (PS). The plastic material is generally lighter than a metal of the same volume, so that the weight of the charging connector can be effectively reduced by using one or more of the materials. Step S10, in which the welding plate and the charging connector are located close to each other and a welding gap is generated between the welding plate and the charging connector, includes:

For example, the electrically conductive layer is formed on the outer surface of the injection-molded part by means of physical vapor deposition or chemical vapor deposition. The material of the conducting layer comprises copper, the conducting layer can also comprise alloy, wherein the alloy conducting layer has oxidation resistance and good hardness, and the thickness of the conducting layer can be deposited according to the requirement of a use design. For example, the thickness of the conductive layer is between 0.05mm and 0.2 mm. When the thickness of the conductive layer is 0.05mm, the processing steps are simple and easy to realize. When the thickness of the conducting layer is 0.2mm, the conducting layer can play a role in supporting the structure of the conducting layer, and the conducting layer is prevented from deforming. In addition, the thickness of the conducting layer can be 0.1mm, so that the conducting layer can be easily processed, and the conducting layer can support the structure of the conducting layer.

Because the tin spraying technology that the tin spraying equipment adopted has non-contact, the heat is little, and the controllable advantage in welding point position can carry out welding operation in the narrow and small welding gap position that welding plate and the joint that charges formed.
Referring to fig. 5 and 6, the present invention further provides a welding device for a charging connector, where the charging connector includes a charging connector 20 and a welding plate 10, where the charging connector 20 includes a conductive metal material, and the charging or signal transmission for a corresponding electronic product is realized through the conductive metal material.

For example, the welding worker directly moves the welding plate 10 by fixing the charging connector 20 by the fixing device, or starts the welding work by moving the welding plate 10 to the charging connector 20 by the moving device. When the distance between welding plate 10 and the joint 20 that charges is fixed, with welding plate 10 and the fixed position of the joint 20 that charges, precision deviation can not appear when guaranteeing to weld, and welding plate 10 and the distance of the joint 20 that charges can effectively guarantee soldering tin 31 and link both together this moment. The welding distance between the welding plate 10 and the charging connector 20 can be adjusted according to the design and use requirements. For example, the width of the welding gap is between 0.05mm and 0.2mm, and when the width of the welding gap is 0.05mm, the positions of the charging connector 20 and the welding plate 10 are tighter, so that the soldering tin can be effectively ensured to be capable of welding and connecting the charging connector 20 and the welding plate 10. When the width of the welding gap is 0.2mm, the tin soldering is easy to spray, in other words, enough space is provided for tin soldering operation, and the smooth operation of the tin soldering operation is ensured. The width of the welding gap can also be 0.1mm, so that the welding connection between the welding plate 10 and the charging connector 20 can be ensured, and enough working space can be provided for tin spraying operation.
