Definitions

  • the invention relates to a connecting device for connecting a conductor end according to the preamble of claim 1.
  • connection devices are known from the state of the art, for example from the generic WO 2013/185893 A1 , whose relatively complicated and self-contained design is intended to reduce the risk of injury to an operator when releasing the contact position.
  • the known connection devices are difficult to operate in terms of their handling and their construction, especially when contacting conductors with a larger diameter, and therefore need to be improved.
  • EN 697 629 T2 discloses a connection device in which a rotary lever arrangement and a clamping spring arrangement have the same direction of rotation when rotating from the open position to the contact position.
  • the technological background also includes the CN 105 428 914 A and the EN 10 2015 118033 A1 called.
  • the object of the invention is to create a connection device that is improved in terms of its handling and its structural design.
  • the rotary lever arrangement and the clamping spring arrangement have the same direction of rotation - at least when rotating from the open position to the contact position or always.
  • the effective lever arm with which the rotary lever arrangement acts on the clamping spring arrangement becomes increasingly larger during the movement from the open position to the contact position.
  • This is particularly advantageous because it increases the force on the clamping spring arrangement before reaching the end contact position, so that a very high force acts on the conductor end before reaching and also in an end contact position, which leads to or results in a high contact force before reaching and in the end contact position to be reached.
  • the actuation forces can nevertheless be kept relatively low - in particular, relatively low.
  • the rotation axis D1 of the clamping spring arrangement and sections of the clamping spring arrangement are arranged above the conductor end to be contacted and above the respective busbar section and that the rotary lever arrangement has a rotation axis D2 which lies above the rotation axis D1 of the clamping spring arrangement.
  • the busbar section is trough-shaped in cross-section, in particular V-shaped or U-shaped, wherein the conductor end can be inserted into the busbar section perpendicular to this cross-section and wherein the clamping spring arrangement is designed to be pivoted into the busbar section at least in sections transverse to the conductor insertion direction in order to press the conductor end in the end contact position into the trough-shaped busbar section in order to contact it.
  • the invention is particularly well suited for this structural design.
  • the rotary lever arrangement has a rotary lever element which is rotatably mounted in or on a preferably central section in the housing and has the axis of rotation and that the rotary lever element has an eccentric section which - preferably on its side facing the clamping spring arrangement - has a control curve along which the actuating legs of the clamping springs slide when moving into the end contact position.
  • the effective lever can be easily adjusted to any angle of rotation and can therefore be optimally adapted to the force required. In this way, a desired lever ratio can be implemented in a simple manner by preselecting the respective dimensions, for example in order to achieve a low actuating force.
  • the eccentric section engages with a projection or a pin or the like inserted into it in a guide of the housing, in particular in an arc-shaped guide.
  • the clamping spring arrangement and/or the actuating leg are additionally fixed in a form-fitting and/or force-fitting manner with a locking device, for example on the busbar section or on another element.
  • a clamping and/or locking means for example the pin already mentioned, can be formed on the eccentric section, which is movable in the link into a fixing position, wherein it is advantageous if the fixing position is formed in the - preferably metallic - busbar section, since in this way a high contact force can also be ensured permanently.
  • actuating leg(s) is/are cranked at its free ends in order to slide on the control cam.
  • the clamping spring arrangement can have a spring carrier.
  • the spring carrier can be formed in one piece with the housing. However, the spring carrier can also - if an actuating leg is arranged on it in a rotationally fixed manner - take over the function of this actuating leg in whole or in part. It then forms part of the clamping spring arrangement in the sense of the claims.
  • Fig.1 a Cartesian coordinate system X/Z is drawn, where the direction perpendicular to the plane of the page is referred to as the "Y direction”.
  • the conductor insertion direction is referred to below as the "X direction”.
  • Fig.1 shows a housing 1, which is designed here as a terminal housing. In the housing, one or more - here two - connection devices 2 are arranged for connecting a respective conductor end 3. In Fig.1 only one of these conductor ends 3 is shown.
  • the conductor ends 3 can be (preferably stripped) single wires or multiple or stranded conductors or, for example, crimped wire ends made of a material with good electrical conductivity - such as copper.
  • the housing 1 consists of electrically insulating material, in particular of a non-conductive plastic.
  • the housing 1 is constructed in a disc-like manner and is preferably designed to be arranged in a row in the Y direction perpendicular to the conductor insertion direction.
  • the terms right, left, top and bottom refer to the representation of the figures and change accordingly when the housing 1 moves in space.
  • the housing 1 can have a fastening foot 11. Here, this is designed to be placed, in particular snapped onto, a support rail (not shown, for example hat-shaped in cross section).
  • the housing 1 also has a top side 12 (this is the side facing away from the fastening foot 11) and two insertion sides 13, 14.
  • the direction perpendicular to the image plane is referred to as the Y direction (the support rail extends in this direction)
  • the direction perpendicular to the support rail in Fig.1 the direction vertically upwards
  • the direction perpendicular to it in Fig.1 to the left
  • the two conductor ends 3 can be moved in and against the X direction.
  • the conductor insertion direction of the right conductor end 3 into the right connection device 2 is thus the X direction and the conductor insertion direction of the left (not shown here) conductor end into the left connection device 2 is the -X direction.
  • connection devices 2 can be designed identically or have a symmetry relative to each other, such as a mirror symmetry to the imaginary plane zz' perpendicular to the plane of the drawing. This means that two conductor ends 3 can be easily and simply inserted into the housing 1 from opposite sides and contacted by the respective connection device 2. This is advantageous, for example, in the embodiment of the Fig. 1 - 3 Furthermore, one, as shown two or more of the connection devices can be arranged in a housing, even next to each other (eg in a multi-part housing1).
  • connection devices 2 each have a clamping spring arrangement 4 and a rotary lever arrangement 5.
  • they each have a busbar section 6, against which the respective conductor end can be pressed or pushed by means of the clamping spring arrangement.
  • the clamping spring arrangement 4 acts in the manner of a compression spring.
  • busbar sections 6 are designed as one piece with one another, so that the two connection devices 2 are conductively connected by a busbar that is here one piece. In this way, a through terminal is realized without an electrical functional module between the two connection devices. It would also be conceivable to design the two busbar sections 6 as separate busbars that are conductively connected to one another directly or via at least one electrical or electronic component.
  • the busbar sections 6 preferably have a V- or U-shape in cross section (see also Fig. 1f ).
  • the main direction of extension of the busbar sections 6 is the X direction perpendicular to this V or U cross section.
  • the respective conductor end 3 is inserted into the connection devices 2 parallel to this main direction of extension (+X, -X).
  • the housing 1 has an insertion opening 17 for the conductor in the extension of the respective busbar section 6.
  • the V or U shape can extend over the entire length of the busbar arrangement in the main direction of extension or over part of the length.
  • the clamping spring arrangement 4 is designed in such a way that it can be pivoted out of the busbar section 6 for inserting the respective conductor end 3, so that a conductor end 3 can be inserted through the insertion opening 17 into the respective busbar section 6.
  • the clamping spring arrangement 4 is pivoted as a whole in the direction of and partially into the busbar section 6, whereby the conductor end 3 is contacted.
  • the clamping spring arrangement 4 finally assumes a fixed position in the contact position and presses the conductor end 3 against the respective busbar section 6 made of electrically highly conductive material, so that at least one contact point is formed through which an electrical current can flow.
  • the clamping spring arrangement 4 consists of several clamping springs 41, 42 (see also Fig. 2a and 3a ), which are designed as leaf springs. After Fig.1 Two leaf springs are provided which serve to generate a sufficient contact force. These leaf springs each have at least one clamping leg 410, 420 and at least one actuating leg 411, 421. The at least one clamping leg 410, 420 and the at least one actuating leg 411, 421 are aligned at an angle to one another, preferably at an acute angle of between 5° and 85°. They are also preferably connected to one another via a bending area 412, 422 or a type of radius. The bending area 412, 422 preferably rests against a spring carrier 45.
  • Fig.2 and 3 the conductor end is not shown in each case, which better illustrates the rotary movement of the clamping spring arrangement 4, which is otherwise influenced by the action of the clamping leg 3 on the conductor end 3.
  • another leaf spring 43 which is a return spring. It is preferably also pre-assembled on the spring carrier 45, rests on this and the clamping springs and can be tensioned when moving into the contact position in order to return the clamping springs 41, 42 when the clamping position is released.
  • the spring carrier 45 can be designed as one piece with the housing 1 or as a separate part of the housing. If it is designed separately from the housing 1, it is advantageous if the clamping spring arrangement 4 can be pre-assembled on the spring carrier 45 and if the pre-assembled unit can then be inserted separately into the housing 1 and secured there, for example in a force-locking and/or form-locking manner, in particular clamping and/or locking.
  • the spring carrier 45 can also be arranged in the housing so that it can pivot. It can then even - if the actuating leg is arranged on it in a rotationally fixed manner - take over the function of this actuating leg 410 in whole or in part. This function shows Fig.3 . It then forms part of the clamping spring arrangement 4 in the sense of the claims.
  • the spring carrier 45 can also be pre-assembled on the busbar, preferably in slots 62 of the busbar sections 6.
  • the clamping springs 41, 42 of the leaf spring arrangement are preferably arranged in a "stack-like" manner, one inside the other. This means that their bending areas 412, 422 lie inside the other and have exactly or essentially the same axis of rotation D1 or D1'
  • the support contour has a rounded pin section 451 around which the clamping springs 41, 42 can rotate in their bending areas 411, 412.
  • the spring carrier 45 serves in the area in which the bending area 412, 422 rests against it, like a bolt, as a pivot bearing for the clamping spring arrangement or for the one or more individual springs or clamping springs of the clamping spring arrangement 4.
  • the actuating legs 411, 421 and/or the clamping legs 410, 420 of the leaf springs 41, 42 are of different lengths. If the actuating legs 411, 421 are of different lengths, this makes it possible to easily contact conductor ends 3 of different diameters very well at positions that are well suited for them. It is also conceivable to contact a single conductor end 3 with two or more leaf springs at different locations.
  • the clamping spring arrangement 4 is preferably aligned such that the bending region 412, 422 is closest to the respective conductor insertion opening 17, so that the clamping leg 410, 420 extends from the bending region 412, 422 away from the conductor insertion opening 17.
  • the respective clamping leg 410, 420 and the respective actuating leg 411, 421 are thus preferably at an acute angle to the conductor insertion direction (X direction).
  • the rotation axes D1 of the clamping spring arrangement(s) 4 and sections of the clamping spring arrangement 4 are in the area of the support contour or the support contour is in the Z direction - i.e. here perpendicular to the fastening foot or the support rail - above the conductor end 3 to be contacted and above the respective busbar section 6.
  • the respective rotary lever arrangement 5, which has a rotation axis D2, is also arranged in the Z direction above the clamping spring arrangement 4.
  • the rotation axis D2 is in the Z direction above the rotation axis D1 of the clamping spring arrangement.
  • the busbar arrangement 6 is arranged at the bottom for each connection device 2 and is directed with its open side of the V- or U-shaped cross section towards the respective clamping spring arrangement 4, so that the clamping leg or legs 410, 420 are inserted into the
  • the rotary axis D2 of the rotary lever arrangement 5 is designed and arranged above the clamping spring arrangement 4.
  • the directions of rotation DR of the rotary lever arrangement 5 and DR of the clamping spring arrangement 4 are the same or in the same direction. They rotate in the Fig.1 left connection device for contacting in a clockwise direction and in the Fig.1 To make contact, turn the right connection device 2 anti-clockwise. To release, turn them in the opposite direction.
  • the rotary lever arrangement 5 With the rotary lever arrangement 5, the clamping spring arrangement 4 can be moved from an open position ( Fig. 1a ) (via several intermediate steps of the Fig. 1b to 1d , Fig.2a to 2e , Fig. 3a to 3e) to a contact position ( Fig. 1e , 2e , 3d ).
  • the rotary lever arrangement 5 has an eccentric shape.
  • the rotary lever arrangement 5 has a preferably disk-like rotary lever element 50 which is rotatably mounted in or on a preferably central section 500 in the housing 1 and has the axis of rotation D2. This can be implemented in various ways.
  • the rotary lever element 50 can be placed on a pin in the housing 1 or can be penetrated by it and/or it can be inserted into a rotary receiving contour 15 of the housing 1 - a receptacle - which surrounds it in sections on the outer circumference.
  • the rotary lever element 50 has an actuating section 501, which is preferably accessible from outside the housing 1, in particular at an opening 16 on the top 12 of the housing 1.
  • the actuating section 501 can be designed, for example, as a projection protruding radially from the central section 500 or as an opening in the area 500, which allows a tool, in particular a screwdriver or the like, to be attached. It can also serve as a stop for limiting the angle of rotation in and/or against the direction of rotation in interaction with an opening 16 of the housing from which it protrudes (see Fig. 2a ).
  • the rotary lever element 50 further comprises an eccentric section 502.
  • the eccentric section 502 is designed here as a type of arm that extends eccentrically, here essentially tangentially, radially outward to the central section 500.
  • the eccentric section 502 has on its side facing the clamping spring arrangement 4 a type of control curve 503, against which the actuating leg(s) 411, 412 of the clamping springs 41, 42 can be brought into contact.
  • the eccentric section 502 can engage with a projection or a pin 504 or the like inserted into it in a guide, in particular an arcuate guide 18, of the housing 1, which ensures a particularly safe and uniform opening movement.
  • the clamping spring arrangement 4 can - for example with an auxiliary spring (not shown here) - be held in the opening position of the Fig.2 or be moved with the conductor end 3 into it when the rotary lever arrangement 5 is rotated into its opening position in which the eccentric section 502 is rotated upwards (away from the busbar section 6).
  • the rotary lever arrangement 5 is now rotated in a direction of rotation "DR" opposite to the direction of rotation "-DR” so that the eccentric section 502 with the control cam 503 comes into contact with the clamping spring arrangement 4 ( Fig. 2b ).
  • the eccentric section 501 acts like a rotary lever - here like an ever-lengthening rotary lever - on the actuating leg(s) 411, 412.
  • it acts on the outer actuating leg 411 and presses it downwards in the -Z direction (here, downwards in the direction of the support rail).
  • FIGS. 1b to 1f - right side of the terminal block shown - show how the area at which the eccentric section 501 touches the clamping spring arrangement 4 moves radially outwards from image to image as the clamping spring arrangement 4 is increasingly closed or pressed against the conductor. Here, this continues until the pin 504 is reached in the radially outermost area of the eccentric section 501.
  • actuating leg 411, 421 and/or the rotary lever arrangement 5 can additionally be fixed in a form-fitting and/or force-fitting manner, for example to the busbar section 6 or to another element, so that a particularly stable end contact position is realized which does not come loose even under higher stresses.
  • the actuating leg(s) 411, 421 can be designed to be cranked at their free ends in order to ensure good sliding of the control cam on the actuating leg(s) 411, 421.
  • the clamping leg(s) 410, 420 press on the conductor end ( Fig. 1d , e ), until preferably the clamping spring arrangement 4 and/or the rotary lever arrangement 5 is/are fixed to an abutment in a form-fitting and/or force-fitting manner.
  • a locking means for example the aforementioned pin 504, is formed on the eccentric section 502, which can be moved into a fixing position in the guide 18.
  • This fixing position is particularly preferably formed in the busbar.
  • the guide 18 in the housing merges into a corresponding guide 60 in the respective busbar section 6 before reaching the locking position or ends in this.
  • the guide 60 in the respective busbar section can have a narrow point 61 or an over-center position in which the pin 504 is securely fixed in position when the end contact position is reached.
  • the end contact position is permanently and securely fixed to the metal busbar 6 and not in the plastic housing 1.
  • Attaching a pin 504 to the eccentric section and forming the locking position in the guide 60 of the busbar section 6 is a particularly simple variant of fixing the spring arrangement in the end contact position, which also results in easy and consistent operation when establishing the contact position and when releasing it. It is also particularly advantageous that no locking hook or the like on the spring arrangement has to be released from a locking position in order to release from the end contact position.
  • the spring carrier 45 is arranged pivotably in the housing 1. It then takes over the function of this actuating arm 411 in whole or in part, since the actuating arm is arranged on it in a rotationally fixed manner. This function shows Fig.3 .
  • the eccentric section 502 acts here via a part of the rotary movement on the spring carrier 45 or on an arm 452 of the spring carrier and rotates the contact spring as well.
  • the clamping leg or legs are exposed and continue to act as clamping spring legs.
  • the spring carrier 45 therefore also forms part of the clamping spring arrangement 4.
  • Fig.4 additionally illustrates the structure of a series terminal using an exploded view.
  • the disc-like structure of the housing 1 in a series-mounted design is clearly visible. It is also clearly visible here that the disc-like housing 1 can be constructed in several parts.
  • the housing 1 can, for example - as shown - be composed of two half-shells 101 and 102.
  • the guide 18 can be formed in one or both of the half-shells 101, 102, which here is aligned at one of its ends with the guide 60 in the respective busbar section 6.
  • the other half-shell is designed here as a rear wall.
