Clamp connection for the attachment of plate-shaped components, particularly solar modules

Abstract

A clamp connection ( 1 ) for the attachment of solar modules, on rail-shaped carriers ( 2 ) provided with guide grooves ( 5 ) with margins ( 6, 7 ) that protrude inwards into the groove ( 5 ), includes a support ( 3 ) with at least one support surface ( 12 ) present on its upper side, for a component. A T-shaped counter bearing ( 9 ) present on its lower side, where a crossbar ( 11 ) of the counter bearing can be inserted and engages behind the protruding margins ( 6, 7 ) of the guide groove ( 5 ), and of a clamping cap ( 4 ) with clamping surface ( 13 ) covering the support surface ( 12 ), and a longitudinal groove ( 16 ) which grips the upper part of the supporting brace ( 5 ), where the clamping cap ( 40 ) and the support ( 3 ) are attached to each other via a latching connection ( 18, 19, 20, 28, 48 ).

1 . A clamp connection for the attachment of plate-shaped components on rail-shaped carriers provided with guide grooves with margins that protrude inwards into the groove, comprising:
 a support with at least one support surface present on its upper side, for a component, and with a supporting brace which delimits the support surface, as well as a T-shaped counter bearing present on its lower side, where said counter bearing includes a crossbar which can be inserted with alignment in the longitudinal direction of the guide groove in the guide groove, and after a rotation by 90° it engage behind the protruding margins of the guide groove, and of a clamping cap with clamping surface covering the support surface, and a longitudinal groove which grips the upper part of the supporting brace, wherein the clamping cap and the support are attached to each other via a latching connection.   
     
     
         2 . The clamp connection according to  claim 1 , wherein the latching connection consists of a latching pin, which is connected to the clamping cap, and which is pressed into a bore in the support, and attached there. 
     
     
         3 . The clamp connection according to  claim 1 , wherein the latching pin is rigidly connected to the clamping cap. 
     
     
         4 . The clamp connection according to  claim 1 , wherein the latching pin has a latching toothing, which engages in a compatible latching toothing provided in the bore. 
     
     
         5 . The clamp connection according to  claim 1 , wherein the latching toothing have sawteeth oriented in opposite directions on the latching pin and in the bore. 
     
     
         6 . The clamp connection according to  claim 1 , wherein the latching pin, over the length of the sawteeth, has at least one longitudinal slot. 
     
     
         7 . The clamp connection according to  claim 1 , wherein an insert is inserted into the bore of the support. 
     
     
         8 . The clamp connection according to  claim 7 , wherein the insert is made of a plastic. 
     
     
         9 . The clamp connection according to  claim 7 , wherein the insert has lateral brackets, which are applied on the lower side of the crossbar of the counter bearing. 
     
     
         10 . The clamp connection according to  claim 7 , wherein the insert is applied with its lower margin on the bottom of the guide groove. 
     
     
         11 . The clamp connection according to  claim 1 , wherein the latching connection consists of a latching pin, which has latching lugs at its end, which engage in cuts at the lower margin of the bore or on a back cut in the bore. 
     
     
         12 . The clamp connection according to  claim 1 , wherein the clamping cap is made of a plastic. 
     
     
         13 . The clamp connection according to  claim 12 , wherein the clamping surface of the clamping cap has a silicon coating. 
     
     
         14 . The clamp connection according to  claim 1 , wherein the clamping cap, on its lower side, has longitudinal notches with back cuts, behind which, on the supporting brace, barbed hooks which are present on a ledge engage by clipping in. 
     
     
         15 . The clamp connection according to  claim 1 , wherein the support is made of an elastomer. 
     
     
         16 . The clamp connection according to  claim 1 , wherein the support is aligned with a support plate. 
     
     
         17 . The clamp connection according to  claim 16 , wherein the support plate and the insert are connected by vulcanization to the support.
