Definitions
- the present invention relates to an electrical connection system for an electrical apparatus such as a terminal block, the system comprising two connection branches to a portion of a support rail.
- a terminal block comprising an electrical connection system for electrically connecting an electrical conductor and a support rail.
- This electrical connection system comprises a conductive strip which is arranged to be electrically connected to both the electrical conductor and the support rail.
- Maintaining cooperation can be difficult because the holding device requires the reduction of the section of the conductive bar for installation.
- the current may well be less well transmitted at this reduced section.
- the present invention aims to solve all or some of the disadvantages mentioned above.
- the present invention relates to an electrical connection system for an electrical apparatus such as a terminal block, the electrical connection system comprising:
- a conductive strip comprising two connection branches arranged to cooperate with a conductive portion of an electrical conductor at a connection position and having a cooperation zone arranged to cooperate with a portion of a support rail at a cooperation position,
- a clamping device arranged to hold the conductive portion in the connecting position, such as a leaf spring comprising a support branch arranged to be mounted to the conductive strip and a clamping branch arranged to hold the conductive portion in the position of bond,
- connection branch has a through opening configured for the passage of a portion of the holding device in the cooperation position.
- the holding device is partly formed in the conductive bar.
- connection branch or branches has the effect of creating two passage channels for the current bypassing the through opening.
- This arrangement therefore makes it possible not to have a zone of weakness in which the transmission of current is reduced at the level of the through opening.
- the clamping device is a device equivalent to the leaf spring, this device being arranged to maintain the conductive portion in the connecting position with the conductive strip.
- the clamping device is a screw clamping device.
- said through opening corresponds to a decrease of between 10% and 50% of a nominal section over a defined length of said at least one corresponding connection branch.
- the nominal section is a section of the at least one corresponding connection leg remote from the through opening.
- the decrease is between 10% and 40% and in particular between 15% and 30%.
- each connection branch has a through opening configured for the passage of a portion of the holding device in the cooperation position.
- This arrangement allows an improvement in the current flow, the current flow section comprising four passage channels.
- a first connection branch comprises a first through opening and a second connection branch comprises a second through opening, the first through opening being opposite the second through opening.
- the first through opening and the second through opening are symmetrical with respect to a central plane.
- This arrangement also facilitates the installation of the holding device: there is no risk of locking the holding device during its installation in the cooperation position.
- each connection branch has a cooperative advance arranged to cooperate with the portion of the support rail in the cooperation position.
- This arrangement makes it possible to effectively tighten the portion of the support rail in the cooperation position and also to ensure good electrical contact.
- the cooperation advances of the connecting branches extend along the same axis in the cooperation position.
- This arrangement improves the cooperation between the connection branches and the conductive strip in the cooperation position.
- At least one connection branch further has a cooperation stop extending transversely to the cooperation advance.
- This arrangement allows a good support in the cooperation position of the portion of the support rail.
- the portion of the support rail comprises a first complementary part with the cooperation advance extending in a first plane and comprises a second complementary part with the cooperation stop extending in a second plane transversal in the foreground.
- This cooperation in two transverse parts allows a good respective positioning of the support rail and the electrical connection system in the cooperation position.
- the engagement stop is obtained from the folding of an end portion of the corresponding branch.
- the holding device comprises a clamping spring provided with two ends facing one another, each end being arranged to cooperate with a clamping location of a corresponding connecting branch.
- At least one clamping location is provided in a cavity of the corresponding connecting branch, said location being arranged to receive a corresponding end of the clamping spring.
- This arrangement allows a simple implementation of the clamping spring on the connecting branches.
- the ends of the clamping spring are thus held in the cavities. There is no risk of movement of the clamping spring relative to the connecting branches.
- each connection branch comprises a cavity as described above.
- connection branch for each connection branch, the cavity and the advance of cooperation are aligned in a direction transverse to the direction of extension of the corresponding branch.
- This arrangement allows optimal application of the tightening force of the clamping spring at the advanced cooperation, which implies a good positional retention of the portion of the clamping rail in the cooperation position.
- each cooperation branch corresponds to a folded blade portion generating the cavity and the advance of cooperation.
- the cavity has a groove shape which allows to easily dispose each end of the clamping spring in the corresponding clamping location laterally with respect to the direction of extension of the corresponding branch.
- the clamping spring has a C-shape.
- This arrangement allows easy insertion of the clamping spring in the through openings.
- the conductive strip has a passage opening for insertion of the conductive portion in the connecting position. This arrangement allows the realization of the conductive strip in one piece having no point of weakness because the current can always be transmitted in sufficient quantities by the two lateral branches generated by the passage opening.
- the conductive strip comprises a first portion and a second portion, the first portion being opposite the second portion.
- This arrangement allows for a compact electrical connection system. This arrangement also makes it possible to adapt the position of the leaf spring I according to the geometrical constraints due to the shape of the terminal block.
- the first part comprises the first connection branch and the second part comprises the second connection branch.
- the conductive strip has a generally U-shaped shape.
- This arrangement makes it possible to produce the conductive strip from a straight strip which is then folded. This arrangement allows a saving of material because a base plate cut into straight blades causes little drop, that is to say loss of material.
- the conductive strip consists of a folded conductive blade.
- the manufacture of the conductive strip is easy since it is made from a cut sheet which is then folded to give the conductive strip its final shape.
- the conductive strip consists of a conductive blade.
- This arrangement facilitates the manufacture of the conductive strip because it comes from a flat blade which is then transformed.
- the mass production of this single conductive part thus makes it possible to save production time and reduce the cost of transformation compared to a system comprising several conductive parts.
- a saving of material is achieved because a base plate can generate a large number of blades, falling material is reduced.
- the conductive blade is included in a rectangular contour. Indeed, since the blade is a rectangle, it is easy to find an arrangement of cuts to be made on the base plate to minimize falls and produce the most conductive bars.
- the conductive strip comprises a recess adapted for fitting by force of a fastening portion of the support branch.
- the depression is achieved by cutting the conductive blade. Depression is thus achieved during the cutting of the conductive blade, which limits the manufacturing time.
- the cut generates a through opening in the conductive strip.
- the present invention also relates to a terminal block comprising an insulating body in which is provided an electrical connection system as described above.
- the insulating body comprises a support portion of the support branch.
- This arrangement makes it possible to ensure the locking of the support branch when the clamping branch is stressed.
- the insulating body comprises a support pad arranged to cooperate with the conductive strip so as to allow the displacement of at least one connecting branch with respect to a corresponding fixed base of said branch adjoining said branch of connection.
- This support pad therefore allows the position of the conductive strip inside the terminal block while allowing the movement of one branch or of the two branches according to its configuration.
- the support pad is arranged to cooperate with a first fixed base of the first connection branch and a second fixed base of the second connection branch.
- the insulating body comprises a centering wall arranged to maintain in position the holding device in the cooperation position.

- Figure 9 is a front view of the terminal block according to the embodiment.
- Figure 10 is a detail view of Figure 9.
- the terminal block 3 includes sockets 9 for electrical conductors.
- Two jacks 9 are connected by a connecting rod 11 to establish an electrical contact between two corresponding conductors.
- the terminal block 3 also has a socket 9 'for an electrical conductor 13 intended to be electrically connected to a support rail 15 on which is removably attached the terminal block 3.
- the electrical conductor 13 has at one end a conductive portion 13 'for example a metal tip.
- the metal tip is arranged to be inserted into an insertion channel 17 of the socket 9 'where it is held in position by the electrical connection system 7.
- the socket 9 'further comprises an operating channel 19 in which a user can introduce a screwdriver type tool for removing the electrical conductor 13.
- the electrical connection system 7 comprises a conductive strip 21 arranged to transmit a current between the conductive portion 13 'of the electrical conductor 13 and a portion 15' of the support rail 15.
- the support rail 15 thus has a dual function since it allows the fixing of the terminal block 3 and is also used to be electrically connected to the electrical conductor 16.
- the electrical connection system 7 also comprises a clamping device 22 of the leaf spring type 23 arranged to hold the conductive portion 13 'in a position of connection with the conductive strip 21 as illustrated in FIGS. 5 to 8.
- any other type of clamping device 22 could be used provided that the clamping device 22 is arranged to hold the conductive portion 13 'in a position of connection with the conductive bar 21.
- a clamping device 22 to screw could for example be used.
- the leaf spring 23 comprises a bearing branch 23 'arranged to be fixed to the conductive bar 21.
- the conductive strip 21 has a recess 25 or a through opening resulting from a cutout adapted for the interlocking force a fixing portion 27 of the support branch 23 '.
- the leaf spring 23 also comprises a clamping leg 23 "joined by a joint 23"'to the support leg 23'. The clamping leg 23 "is arranged to hold the conductive portion 13 'in the connecting position.
- the maneuvering channel 19 is arranged so as to allow the displacement of the clamping branch 23 "for the withdrawal of the electrical conductor 13.
- the insulating body 5 has a support portion 29 of the support branch 23 'whose function is to block the support arm 23' during the movement of the clamping branch 23 ".
- the conductive strip 21 has a folded end portion 31 generating a first portion 33 'of a cooperation zone 35 or advanced cooperation 33 and a second portion 37' of the cooperation zone 35 or stop cooperation 37.
- This first portion 33 'of the conductive strip 21 is arranged to cooperate with a first complementary portion 39 of the support rail 15 extending in a first plane 39'.
- This second portion 37 'of the conductor bar 21 is arranged to cooperate with a second complementary portion 41 of the support rail 15 extending along a second plane 41' transverse to the first plane 39 '.
- the conductive strip 21 also has a longitudinal contact surface 43 on which are formed an electrical contact location 45 with the conductive portion 13 'in the connection position, the cooperation advance 33 and the cooperation stop 37.
- the electrical contact location 45 extends rectilinearly in a profile generating one or more grooves for better maintenance of the conductive portion 13 'in the connecting position.
- the conductive strip 21 further has a passage opening 47 for the insertion of the conductive portion 13 'in the connecting position.
- This passage opening 47 results for example from a cut made before folding of the conductive bar 21.
- the electrical connection system 7 also comprises a holding device 49 arranged to hold the support rail 15 in a position of cooperation with the conductive bar 21. The cooperation is by contact, which allows a current transmission between the conductive strip 21 and the support rail 15.
- the conductive strip 21 comprises a first part 51 and a second part 53 at least partially opposite the first part 51.
- the first part 51 comprises the longitudinal contact surface 43 and the second part 53 cooperates with the holding device 49. Having these two parts 51, 53 makes it possible to produce a compact electrical connection system 7 and / or to adapt to geometrical constraints imposed on the terminal block 3.
- the conductive strip 21 can thus be obtained by cutting in a base plate and then by folding.
- the conductive strip may have a generally U-shaped shape.
- the first part 51 and the second part 53 are each formed in a different branch of the U.
- the general U shape of the conductive strip 21 is obtained from a conductive strip cut from a base plate.
- the blade is included in a rectangular contour which allows a saving of material by limiting the falls during cutting. When cutting through openings are also created.
- This arrangement makes it possible to maintain a large section for good power transmission once the conductive strip 21 is folded.
- the conductive strip 21 when folded also has good strength and is not likely to be deformed during assembly in the terminal block 3.
- the holding device 7 comprises a clamping spring 61 comprising a first end 61a and a second end 61b facing the first end 61a.
- the clamping spring 61 thus provides a clamping force between its two ends 61a, 61b. It is arranged to maintain the cooperation between the portion 15 'of the support rail 15 and the conductive bar 21 in the cooperation position.
- the conductive strip 21 comprises a first connection branch 63a and a second connection branch 63b respectively mobile with respect to a first fixed base 65a and a second fixed base 65b adjacent to the conductive strip 21.
- a support stud 67 moves the connection branches 63a, 63b while keeping the fixed bases 65a, 65b in position.
- the connecting branches 63a, 63b operate as a jaw enclosing the portion 15 'of the support rail 15 in the cooperation position.
- the first connecting branch 61a has a first through opening 69a and the second connecting leg 61b a second through opening 69b.
- the first through opening 69a and the second through opening 69b are facing each other and symmetrical with respect to a central plane 71.
- Each through aperture 69a, 69b generates two channels 73 of current flow, which allows good power transmission in the conductive strip although material has been removed to provide said opening.
- connection branch 63a, 63b also has a cavity 75a, 75b in the form of a groove extending aligned with the corresponding cooperation advance 33 in a direction transverse to the central plane 71.
- a clamping location 77a, 77b is provided in said cavity 75a, 75b of each connecting branch 63a, 63b.
- a first clamping location 77a is arranged to receive the first end 61a of the clamping spring 61 and a second clamping location 77b the second end 61b.
