Description

Technical Field

[0001] The utility model relates to a plate for welding, in particular to a plate for welding which is used for connecting with a socket sleeve. Background Art

[0002] With the rapid popularization of various electronic products such as mobile phones, tablets, and laptops, sockets have become one of the most widely used electrical devices in our daily lives.

[0003] In the socket, the connection between the socket and the copper strip is often made by soldering. Fig. 8A and Figure 8B As shown, after the copper strip is placed in the predetermined position of the socket, the welding side surface of the copper strip is butt-welded to the bubble point of the socket by a butt welding machine to integrate the two. Fig. 8A The figure is a three-dimensional schematic diagram showing an example structure of connecting a socket and a copper strip in the prior art. Figure 8B Yes Fig. 8A The red frame portion in the figure is enlarged, that is, an enlarged stereoscopic schematic diagram of an example structure obtained by butt-welding the welding side surface of the copper strip and the bubble point of the socket by a butt welding machine in the prior art.

[0004] In addition, the structure of the copper strip before welding is a long flat plate, such as Figure 6 and Figure 7 shown. Figure 6 1 is a schematic diagram showing an example of a welding side surface of a conventional copper strip. Figure 7 It is shown Figure 6 The cross-sectional view of the copper strip shown is a cross-sectional view obtained by cutting along B1-B1. Utility Model Content

[0005] However, the above-mentioned existing butt welding technology has the following problems: (1) The consistency of the position and size of the socket bubble point is difficult to control, which may result in unqualified welding depth; (2) The socket bubble point is set on the connecting end of the socket, which will increase the thickness of the local area, so that when the socket is installed on the socket seat, the opening at the bottom of the socket seat through which the connecting end of the socket passes needs to be widened (that is, a avoidance groove for the socket bubble point needs to be reserved on the socket seat), resulting in a large gap between the opening and the bottom of the connecting end, which may result in poor strength of each pole hole; (3) The stamping of the socket adds a stamping bubble point process, and a special mold needs to be added for the socket with the socket bubble point, making the manufacturing more complicated; (4) The effective contact area between the socket and the copper strip after welding is small; (5) Copper material overflow may occur after welding; (6) The current power used during welding is relatively large.

[0006] The utility model is completed in view of the above situation, and its purpose is to provide a plate for welding including a plurality of grooves. After the plate for welding is butt-welded with the surface of a socket, the molten alloy material will fill the grooves on the plate for welding, so that the plate for welding is tightly connected with the socket, without the need to set an additional socket bubble point on the socket.
