Abstract

A clamp connector includes a first clamping member configured to apply a clamping force to a material, the first clamping member having a first portion including a first and second cam surfaces, a first cammed body adjacent the first cam surface, and a second cammed body adjacent the second cam surface. A second clamping member is configured to apply a clamping force to the material. The second clamping member having a second portion including a third and fourth cam surfaces, a third cammed body adjacent the third cam surface, and a fourth cammed body adjacent the fourth cam surface. When each cam surface is forced against the adjacent cammed body a clamping force between the first clamping member and the second clamping member is increased.

First claim

What is claimed:

1. A clamp connector having a longitudinal axis defining a longitudinal plane containing the longitudinal axis and a transverse plane containing the longitudinal axis, the transverse axis perpendicular to the longitudinal plane, the clamp connector comprising:
a first containing member including portions positioned on either side of the longitudinal plane, a first containing member first cam surface and a first containing member second cam surface;
a first clamping member adjacent the first containing member, the first clamping member including a first clamping member cam surface;
a second clamping member adjacent the first containing member, the second clamping member including a second clamping member cam surface;
a second containing member including portions positioned on either side of the longitudinal plane, a second containing member first cam surface and a second containing member second cam surface;
a third clamping member adjacent the second containing member, the third clamping member including a third clamping member cam surface;
a fourth clamping member adjacent the second containing member, the fourth clamping member including a fourth clamping member cam surface;
a first material portion disposed between the first and third clamping members, the first material portion having a first portion edge defining a laterally inboardmost extent of the first material portion, the first clamping member and the third clamping member each having a maximum thickness at the first portion edge of the first material portion; and
a second material portion disposed between the second and fourth clamping members, the second material portion having a second portion edge defining a laterally inboardmost extent of the second material portion, the second clamping member and the fourth clamping member each having a maximum thickness at the second portion edge of the second material portion;
wherein the first containing member first cam surface, the first clamping member cam surface, the second containing member second cam surface, and the third clamping member cam surface each slope in a first direction; and
wherein the first containing member second cam surface, the second clamping member cam surface, the second containing member first cam surface, and the third clamping member cam surface each slope in a second direction opposite the first direction;
wherein the first clamping member abuts the second clamping member at the longitudinal plane and the third clamping member abuts the fourth clamping member at the longitudinal plane.

2. The clamp connector of claim 1 , wherein a first magnitude of the first slope is equal to a second magnitude of the second slope.

3. The clamp connector of claim 1 , wherein the first containing member first cam surface, the first containing member second cam surface, the first clamping member cam surface, the second clamping member cam surface, the second containing member first cam surface, the second containing member second cam surface, the third clamping member cam surface, and the fourth clamping member cam surface are each positioned closer to the transverse plane with increasing distance from the longitudinal plane.

4. The clamp connector of claim 1 , wherein the first material portion and the second material portion comprise portions of the same piece of material.

5. The clamp connector of claim 4 , wherein the single piece of material comprises a metal grid material.

6. The clamp connector of claim 5 , wherein the single piece of material forms part of an exhaust gas silencer.

7. The clamp connector of claim 1 , wherein the first and second portions of material are substantially flat.

8. The clamp connector of claim 1 , wherein:
the first and second clamping members are in contact with the first containing member; and
the third and fourth clamping members are in contact with the second containing member.

9. The clamp connector of claim 1 , further comprising at least one fastener coupling the first containing member to the second containing member.

10. A clamp connector having a longitudinal axis defining a longitudinal plane containing the longitudinal axis and a transverse plane containing the longitudinal axis, the transverse axis perpendicular to the longitudinal plane, the clamp connector comprising:
a first containing member positioned on either side of the longitudinal plane, the first containing member including a first containing member first cam surface and a first containing member second cam surface;
a first clamping member including a first clamping member cam surface positioned adjacent the first containing member first cam surface, wherein a thickness of the first clamping member decreases with increasing distance from the longitudinal plane;
a second clamping member including a second clamping member cam surface positioned adjacent the first containing member second cam surface, wherein a thickness of the second clamping member decreases with increasing distance from the longitudinal plane;
a second containing member positioned on either side of the longitudinal plane, the second containing member including a second containing member first cam surface and a second containing member second cam surface;
a third clamping member including a third clamping member cam surface positioned adjacent the second containing member first cam surface, wherein a thickness of the third clamping member decreases with increasing distance from the longitudinal plane;
a fourth clamping member including a fourth clamping member cam surface positioned adjacent the second containing member second cam surface, wherein a thickness of the fourth clamping member decreases with increasing distance from the longitudinal plane;
a first material portion disposed between the first and third clamping members, the first material portion having a first portion edge defining a laterally inboardmost extent of the first material portion, the first clamping member and the third clamping member each having a maximum thickness at the first portion edge of the first material portion; and
a second material portion disposed between the second and fourth clamping members, the second material portion having a second portion edge defining a laterally inboardmost extent of the second material portion, the second clamping member and the fourth clamping member each having a maximum thickness at the second portion edge of the second material portion;
wherein the first clamping member abuts the second clamping member at the longitudinal plane and the third clamping member abuts the fourth clamping member at the longitudinal plane.

11. The clamp connector of claim 10 , wherein the first containing member first cam surface, the first containing member second cam surface, the first clamping member cam surface, the second clamping member cam surface, the second containing member first cam surface, the second containing member second cam surface, the third clamping member cam surface, and the fourth clamping member cam surface are each positioned closer to the transverse plane with increasing distance from the longitudinal plane.

12. The clamp connector of claim 10 , wherein the first material portion and the second material portion comprise portions of the same piece of material.

13. The clamp connector of claim 12 , wherein the single piece of material comprises a metal grid material.

14. The clamp connector of claim 12 , wherein the single piece of material forms part of an exhaust gas silencer.

15. The clamp connector of claim 10 , wherein:
the first and second clamping members are in contact
