Title:
ASSEMBLY STRUCTURE OF KEYBOARD COMPONENT
Document Type and Number:
Japanese Patent JP2003281956
Kind Code:
A
Abstract:

To provide an assembly structure for increasing the number of required connection terminals, without narrowing the pitch between the connection terminals in a contact-point array of a membrane and a printed board.

A contact-point terminal of a printed board (5) is made to contact, for assembly, with the contact-point terminal of a membrane (2) disposed on a frame or a base plate of a keyboard. Contact-point terminals (3a and 4a; 7a and 8a) of the membrane (2) and the printed board (5), facing each other, are arrayed with the same pitch. A first contact-point array (3 and 7) disposed in the length direction of the membrane and a second contact-point array (4 and 8) disposed in the direction orthogonal to the first contact-point array are provided. The first contact-point array has a coarse pitch (P1) while the second contact-point array has a fine pitch (P2). Thus, the number of contact-point terminals is increased coping with temperature changes without narrowing the pitch of the contact-point array.
