During production, the connection terminal 2220 and the housing 2210 are combined with prisoner molding. Prior to injection molding, the metal connection terminal 2220 is first placed and fixed in a cavity of an injection mold, and then an injection molding material is injected into the cavity to effect injection molding. The connection terminal 2220 includes an input terminal 2221, two output terminals 2222, and a connecting piece 2223. The two output terminals 2222 are connected to the input terminal 2221 by means of the workpiece. 2223. The input terminal 2221, the two output terminals 2222, and the connection piece 2223 are formed in one piece.
