Description

Clamping device for tightening and clamping a strip and clamping assembly comprising such a clamping device
The present invention relates to a clamping device for wedging and clamping a strip, of the type comprising:
- a rigid housing member delimiting a passage extending longitudinally between an inlet and an outlet, and
- a slide member to be inserted longitudinally into the passage through the inlet, wherein biasing the slide member longitudinally towards the outlet causes the slide member to be biased transversally towards a clamping wall of the housing member delimiting the passage, so as to clamp portions of the strip received into the passage between the slide member and the clamping wall.
The document US 3 587 142 describes a clamping device of the aforementioned type, wherein the strip is rolled into a coil against the slide member to bias the slide member into the passage of the housing member, and the slide member is provided with steps which contact the housing member once the tension applied to the strip exceeds a predetermined value to cause a sudden movement of slide member and a firm clamping of the strip at the position and tension attained.
An aim of the invention is to provide such a clamping device which is easy to implement.
According to the invention, one proposes a clamping device of the aforementioned type, further comprising the feature of the characterizing part of claim 1.
Thanks to the resilient portion, the slide member is automatically biased is the housing member for a good wedging of the strip.
In other embodiments, the clamping device may comprise any of the features of any one of the dependant claims, considered individually or in any technically feasible combination: The invention will be better understood on reading the following description, given only by way of example, and made with reference to the appended drawings, in which:
- Figure 1 is a perspective view of a clamping assembly comprising a clamping strip and a clamping device according to the invention and,
- Figure 2 is a cross-sectional view of the arrangement of Figure 1 wherein the strip is wedged and clamped around an object.
As illustrated on Figure 1 , the assembly 2 comprises a clamping device 4 adapted to wedge and clamp a strip 6. Possibly, one may use a tool 8 for pulling the free end of the strip 6 or adapted pliers.
In a known manner, the strip 6 is adapted to be rolled into a coil with a plastic permanent deformation, whereby the strip 6 remains in rolled state. The strip 6 is made for example of metal or plastic,
The tool 8 comprises for example a pin 10 having a slot 12 extending therein along the length of the pin 10 from a free-end 14 thereof. The slot 12 is adapted to receive the strip 6 so has to roll a portion thereof around said pin 10.
The clamping device 4 comprises a tubular housing member 16 having a rear open end 18 forming an inlet, a front open end 20 forming an outlet, and a passage 22 extending therebetween along a longitudinal direction L. The passage 22 is tapered from inlet 18 to outlet 20, inlet 18 being larger than outlet 20.
The passage 22 is defined between two confronting lower 24 and upper 26 walls of the housing member 16. The walls 24 and 26 are inclined one with respect to the other, and are converging progressively from inlet 18 to outlet 20. The walls 24 and 26 are closer at outlet 20 than at inlet 18. The wall 24 defines a clamping wall. The passage 22 is delimited laterally by two parallel walls 27 each extending between walls 24 and 26.
The device 4 comprises a slide member 28 adapted to be inserted into the passage 22 through inlet 18. The slide member 28 comprises a wedge-like front portion 30 which is rigid and adapted to be accommodated into passage 22. The portion 30 is complementary in shape to passage 22 and tapers from a rear end 32 thereof to a front end 34 thereof.
The slide member 28 comprises a rear portion 36 fixed to the front portion 30 at the rear end 32 thereof, and separated from the front portion 30 along a transversal plan substantially perpendicular to the longitudinal direction L.
The rear portion 36 is made of a resilient material, which is more resilient than the material of portion 30. Portion 30 is for example made of plastic material or metal, and portion 36 is for example made of natural or synthetic rubber. Alternatively, the rear portion comprises a plastic or metallic spring, The operation of assembly 2 will now be explained with reference to Figure
2.
The strip 6 is passed through the passage 22 such that a portion 40 of the strip 6 is accommodated in the passage 22 over the wall 24. An end portion 42 of the strip 6 extending from portion 40 and projecting out of the passage 22 through the outlet 20 is folded under the wall 24.
The housing member 16 is placed against the surface 43 of an object 44 with the end portion 42 placed between the wall 24 and the surface 43.
Thereafter, the strip 6 is passed around the object 44, and is passed again through passage 22, rearward from outlet 20 to inlet 18, such that a portion 46 of the strip 6 is passed through passage 22 and placed over portion 40, and an end portion 48 extending from portion 46 extends out of passage 22 through inlet 18. Thereafter, the portion 30 of the slide 28 is inserted into passage 22 as indicated by arrow F1 through inlet 18, between portion 46 and wall 26. The rear end 32 protrudes from inlet 18. Thereafter, the end portion 48 is passed through the slot 12 of the tool 8.
This latter is turned about the axis of pin 10 so as to roll the portion 48 of the strip 6 around pin 10 (arrow F2) into a coil 50.
The coil 50 is rolled until it abuts against a rear face 52 of the rear portion
36. Further rolling the coil 50 tightens the strip 6 and biases the slide 28 longitudinally frontward towards the outlet 20 (arrow F1 ). The slide 28 is thus biased against wall 26. Since wall 26 is inclined relative to wall 24, the slide 28 is biased transversally towards wall 24 (arrow F3), whereby the portions 40 and 46 are clamped between the slide 28 and the wall 24 (arrow F2).
Rolling the coil 50 simultaneously causes tightening of the strip 6 and clamping of the strip 6 between the slide member 28 and the wall 24. The coil 50 is rolled until the necessary tension is applied to the strip 6.
When biasing the slide member 28, the rear portion 36, which is resilient, will be compressed longitudinally. Therefore, for a given tightening of the strip 6, the angular stroke of the coil 50 is greater than in the case in which the rear portion 36 would be rigid. Consequently, a longer displacement of coil 50 is necessary to unclamp the strip 6, and such a displacement is less likely to occur involuntary. Thus, the clamping device enables to tighten and clamp a strip around an object more reliably in a very simple manner.
The device is very simple to manufacture. In the case the rear portion 36 is made of rubber or plastic material, it is for example adhered or overmoulded on the front portion 30.
The assembly 2 is usable for example for clamping strips around tubular bodies for connecting such bodies between them, or for fixing an electrical connector on an electricity pole or pylon.
