Abstract

A mounting member or connecting device is used to connect a first member to a second member. The connecting device includes a male member and a female member which are coupled together through an opening in the first member. The first member may be a divider panel and the second member may be a cover panel, for example, with the second member having first and second parallel fingers thereon. A tolerance ring, formed in the shape of a band which is less than a complete circle. is mounted on a cylindrical section of the male and female members. The tolerance ring has corrugations thereon which are crushed to some degree when the first and second fingers are pushed on to the associated cylindrical section with the tolerance ring thereon. This connection provides a vibration free connection and also eliminates ESD problems between the connected members.

Claims

1. A connecting device for connecting a first panel to a second panel, said first panel having first and second substantially parallel fingers extending therefrom, said connecting device comprising:

a male member having a head and a cylindrical section having an associated longitudinal axis, with said male member secured to said second panel and with said cylindrical section upstanding from said second panel; and

a tolerance ring made from a strip of stainless steel which is formed into a band which is less than a complete circle, said tolerance ring positioned on said cylindrical section;

said tolerance ring having corrugations thereon which are aligned with said longitudinal axis of said cylindrical section; and

said cylindrical section with said tolerance ring thereon forming an interference fit with said first and second parallel fingers.

2. The connecting device as claimed in claim 1 in which said first panel is made of non-conducting material and has a layer of conducting material thereover, and said second panel is made of electrically conducting material.

3. A combination comprising:

a first member having an opening therein;

a second member having first and second parallel fingers extending therefrom; and

a connecting device for connecting said second member and said first member together;

said connecting device comprising;

a male member having first and second concentric cylindrical sections thereon relative to an associated longitudinal axis;

a female member having a hole therein; and

a tolerance ring having an exterior, with corrugations on the exterior thereof, with said tolerance ring positioned on said first cylindrical section, and with said corrugations aligned with said longitudinal axis;

said second cylindrical section passing through said opening in said first member and being retained in said hole in said female member; and

said first cylindrical section with said tolerance ring thereon forming an interference fit with respect to said first and second parallel fingers.

4. The combination as claimed in claim 3 in which said first and second members are made of electrically conducting material having a layer of conducting material thereon.

5. The combination as claimed in claim 4 in which said male member has a head portion and said tolerance ring has first and second sides, with said first side of said tolerance ring abutting against said head portion and said second side of said tolerance abutting against one side of said first member.

6. The combination as claimed in claim 5 in which said tolerance ring is made of a strip of stainless steel which is formed into less than a complete circle.

7. The combination as claimed in claim 6 in which said female member has a cylindrical section thereon with said hole passing through said cylindrical section, and said combination also comprises:

a third member having first and second parallel fingers extending therefrom, with said second member positioned on said one side of said first member and said third member positioned on a remaining side of said first member; and

a tolerance ring positioned on said cylindrical section of said female member, with said tolerance ring on said female member having first and second sides, and with said last named first side positioned next to said head of said female member and with said last named second side positioned next to said remaining side of said first member;

said cylindrical section of said female member with the associated said tolerance ring thereon forming an interference fit with respect to the associated first and second parallel fingers of said third member.

8. The combination as claimed in claim 7 in which said tolerance ring on said female men, her is made of a strip of stainless steel which is formed into less than a complete circle.

9. A connecting device for connecting first and second panels to a third panel;

said first and second panels each having associated-first and second parallel fingers extending therefrom; and

said third panel having an opening therein;

said connecting device comprising;

a male member having a head and first and second concentric cylindrical sections having an associated longitudinal axis, with said first cylindrical section positioned between said head and said second cylindrical section;

a female member having a head and a cylindrical section, said female member having hole passing through said head and cylindrical section;

said second cylindrical section passing through said opening in said third panel and through said hole in said female member to retain said male and female members on opposed sides of said third panel;

a first tolerance ring having corrugations on the exterior thereof, with said first tolerance ring positioned on said first cylindrical section of said male member;

a second tolerance ring having corrugations on the exterior thereof, with said second tolerance ring positioned on said cylindrical section of said female member; and

said corrugations on said first and second tolerance rings aligned with said longitudinal axis;

said first cylindrical section with said first tolerance ring thereon forming an interference fit with respect to the associated first and second parallel fingers on said second panel; and

said cylindrical section of said female member with said second tolerance ring thereon forming an interference fit with respect to the associated first and second parallel fingers on said first panel.

10. The connecting device as claimed in claim 9 in which each of said first and second tolerance rings is made of a strip of stainless steel which is formed into less than a complete circle.

11. The connecting device as claimed in claim 10 in which said first and second panels are made on non-electrically conducting material having a coating of electrically conducting material thereover, and said third panel is made of electrically conducting material.

12. The connecting device as claimed in claim 10 in which said first, second, and third panels are made electrically conducting material having a coating of electrically conducting material thereover to prevent rusting.
