Abstract
A cam operated spacing device is provided for securing electronic circuit boards to a chasis in spaced parallel relationship to one another and for maintaining this spacing in environments when the circuit boards are subjected to high shock and vibration. The lobes of the cam-lock device are rotated 180.degree. to cause the lobes to engage the edges of apertures in the circuit boards and secure the circuit boards in place.
Claims5
A device for maintaining the proper spacing for circuit boards comprising:
- a housing for mounting electronic circuit boards;
- a chassis circuit board mounted onto said housing;
- a plurality of circuit boards having one end secured to said chassis circuit board at a right angle, and having apertures centrally located within said circuit boards;
- and
- a cam-lock shaft mounted onto said housing wherein adjacent lobes of said cam-lock shaft are positioned to engage the edges of said apertures of said circuit boards, thereby securing said circuit boards in proper spaced alignment with adjacent circuit boards.
