Abstract

A mounting clip for a rotary potentiometer. In a preferred embodiment, the mounting clip comprises front and back generally vertical opposing side segments elastically deformable relative to each other between a naturally biased position and an outward flexed position. The back side segment defines a pair of legs sized to accommodate a shaft of the potentiometer. The mounting clip is useful for mounting the rotary potentiometer relative to a support wall of a joystick assembly in a position wherein a body portion of the potentiometer is adjacent to the support wall and the shaft of the potentiometer projects through an opening in the support wall. When the potentiometer is so positioned, the mounting clip may be slid downward over the potentiometer and support wall such that the front side segment overlies an outer flat surface of the potentiometer and the legs straddle the shaft of the potentiometer on the other side of the support wall. Because the potentiometer shaft projects non-fixedly through the legs and the opening in the support wall, it is permitted to deflect in response to intermittent side-loading forces.

Claims

1. A potentiometer mounting system comprising:

a potentiometer defining a body portion and a shaft;

a support wall having an opening therein for accommodating the potentiometer shaft;

a mounting clip having front and back generally vertical resilent opposing side segments and a top segment bridging the front and back side segments;

wherein said potentiometer is secured to said support wall by a compressive force component applied by said mounting clip parallel-to take shaft, the body portion of said potentiometer and a portion of said support wall is received and retained between the front and back side segments of said mounting clip and the potentiometer shaft projects through the opening in said support wall.

2. The potentiometer mounting system of claim 1 wherein the potentiometer shaft projects non-fixedly through the opening in said support wall.

3. The potentiometer mounting system of claim 1 wherein the potentiometer shaft is subject to intermittent side-loading forces, the potentiometer shaft projecting non-fixedly through the opening in a manner which permits deflection of the potentiometer shaft in response to said side-loading forces.

4. The potentiometer mounting system of claim 1 wherein said mounting clip has a generally U-shaped cross section.

5. The potentiometer mounting system of claim 1 wherein the back side segment comprises a pair of legs, the potentiometer shaft projecting between the legs and through the opening in said support wall.

6. The potentiometer mounting system of claim 1 wherein the front and back side segments are elastically deformable relative to each other between a naturally biased position and an outward flexed position, the front and back side segments being deformed to the outward flexed position in a position overlying and compressing therebetween the body portion of said potentiometer and a portion of said support wall.

7. The potentiometer mounting system of claim 1 wherein said mounting clip is of unitary construction.

8. The potentiometer mounting system of claim 7 wherein said mounting clip comprises spring steel.

9. The potentiometer mounting system of claim 8 wherein the front and back side segments have a thickness of about 20 mils.

10. A potentiometer mounting system comprising:

a potentiometer defining a generally disk-shaped body portion and a shaft, the body portion comprising an outer flat surface and an inner flat surface bridged by a cylindrical surface, the potentiometer shaft projecting outwardly from the inner flat surface along a longitudinal axis;

a support wall having an opening therein for accommodating the potentiometer shaft,

a mounting clip comprising front and back generally vertical opposing side segments and a top segment bridging said front and back side segments, the front and back side segments being elastically deformable relative to each other between a naturally biased position and an outward flexed position;

wherein said potentiometer is secured to said support wall by said mounting clip, the front and back side segments deformed outwardly in a position overlying and compressing therebetween the body portion of said potentiometer and a portion of said support wall such that the outer flat surface of said potentiometer is adjacent to the front side segment of said mounting clip, and the inner flat surface of said potentiometer being adjacent to said support wall and the potentiometer shaft projecting through the opening in said support wall.

11. The potentiometer mounting system of claim 10 wherein a bottom portion of the front side segment turns inwardly toward the back side segment to define a bottom flange, the bottom flange underlying a portion of the cylindrical surface of said potentiometer and retaining said mounting clip in position about said potentiometer.

12. The potentiometer mounting system of claim 10 wherein the front side segment of said mounting clip has a generally circular opening therein defining a clearance hole, the clearance hole being centered about the longitudinal axis such that it overlies a center portion of the outer flat surface of said potentiometer.

13. The potentiometer mounting system of claim 10 wherein said potentiometer includes a group of electrical terminals for receiving wires extending sidewardly from the cylindrical surface, the front side segment of said mounting clip defining at least one wire clearance notch, the wire clearance notch generally overlying the electrical terminals thereby providing clearance space for the electrical wires.
