る。As is apparent from the above description, according to the present invention, the external connection contacts are fixed to the printed wiring board by soldering, and these external connection contacts are formed on the housing case. Into the corresponding contact mounting groove
By omitting parts for electrically coupling the printed wiring board and the external connection contacts, the manufacturing cost can be reduced. Also, according to the manufacturing method of the present invention, skill is required to fix the external connection contacts directly to the printed wiring board, and then to attach the external connection contacts to the contact mounting grooves in the step of fixing the printed wiring board to the housing case. The assembly work can be performed efficiently without using any tools. In particular, in the manufacturing process using contact blanks, the external connection contacts can be fixed to the printed wiring board while maintaining the alignment of the processed external connection contacts, and these external connection contacts can be separated later, further improving work efficiency. There is an effect that can be done.
