Abstract

A fan holder used to mount standard type "muffin" or similar fans to power and logic printed circuit boards without the use of screws, bolts or rubber suspension systems is constructed as follows. Referring to the drawings, the fan holder is first secured to the printed circuit board as shown in Fig. 1. The posts 1 are pushed in, flexing the part and allowing the pins 2 to be inserted into the hold in the printed circuit board 3. Upon release of the posts 1, the pin seats itself on the second radius in the pin groove 4 (Fig. 2). The leaf spring 5 completes the locking mechanism.

Fan Holder

A fan holder used to mount standard type "muffin" or similar fans to power and logic printed circuit boards without the use of screws, bolts or rubber suspension systems is constructed as follows. Referring to the drawings, the fan holder is first secured to the printed circuit board as shown in Fig. 1. The posts 1 are pushed in, flexing the part and allowing the pins 2 to be inserted into the hold in the printed circuit board 3. Upon release of the posts 1, the pin seats itself on the second radius in the pin groove 4 (Fig. 2). The leaf spring 5 completes the locking mechanism.

To attach the fan to the fan holder, the fan housing 6 is seated in place by pressing it onto the two spring pins 7 provided on the top of the fan holder posts
1. The fan is then secured by snapping the lock arms 8 over the fan housing and into the mounting holes on the top side of the fan housing. The simplicity of the fan holder is achieved by taking advantage of the fan housing as the main superstructure. Two identical fan holder parts are used per fan.

The fan holder is a non-conductive plastic part of polycarbonate, thereby eliminating the possibility of causing any electrical short problems. Because of this, it lends itself to use on logic and printed circuit boards. Since the fan holder is plastic and the fan retention system is based on spring action, vibrations from the fan to the machine are minimized. Field replacement of the fan merely requires that the lock arms be...
