ABSTRACT:
A guide rail for a printed circuit board mounted in a partially conductive housing comprises a conductive guide member and an insulative fixing member. The guide member is inserted into a receiving portion of the fixing member from an inlet formed in the bottom thereof. In this condition, contact members of the guide member project outwardly from the inlet. Then, the fixtures of the fixing member are secured to the housing. Since the operator only touches the insulative fixing member to perform the above mounting, corrosion of the guide member is prevented. The contact members projecting outwardly from the inlet is deflected toward the receiving portion of the fixing member when the fixing member is secured to the housing, thereby intimately contacting to a conductive portion of the housing. Thus, a stable connection between the guide member and the housing is attained. Further, since the fixing member is formed of insulative material, short circuiting of the printed circuit board is prevented even if a member for supporting the board contacts the fixing member.
