Description

Field of the Invention

[0001] The present invention relates to a connecting device for connecting electrical conductors. Background Art

[0002] Electrical connecting devices with different structural forms have been disclosed in practice. In the case of screw-type connectors, for example, a wire with a stripped insulating conductor end is inserted into a socket, and then the wire is clamped to the screw-type connector by screwing. In the case of spring terminals, the electrical conductor is inserted into the socket and abuts against the legs of a spring, where the spring acts on the electrical conductor in such a way that the electrical conductor is mechanically locked and, for example, also makes electrical contact with a current bar.

[0003] Such a connecting device is described in DE 10 2019 121 442 A1. In this case, the clamping element consists of a leg spring with contact legs. The contact legs are pre-tensioned to a clamping position and can be held in a release position for operation.

[0004] WO 2021 / 095676 A1 discloses another connecting device including a leg spring, which includes clamping feet pre-tensioned to a clamping position. A tripping mechanism triggered by the inserted electrical conductor causes the clamping feet to move out of the release position and snap into the clamping position. A component of the tripping mechanism is connected to a display element, and depending on the position of this component, the display element visibly displays the clamping state of the connecting device from the outside.

[0005] Another mechanism for displaying the contact state of an inserted electrical conductor is described in DE 11 2019 001 295 T5.

[0006] The connecting devices described in the above two publications can display the position of the clamping element, which is usually not visible or not clearly visible from the outside, to the user, but these connecting devices all have drawbacks. The display element is easily overlooked and is prone to jamming due to its relatively complex structure. Summary of the Invention

[0007] The object of the present invention is to provide an improved connecting device for connecting electrical conductors.

[0008] Accordingly, there is provided a connecting device for connecting electrical conductors, the connecting device including a housing having a conductor connection cavity, a clamping element, and a manipulation element supported in a manner capable of moving relative to the housing and operatively connected to the clamping element, the clamping element being capable of moving from a release position releasing the conductor connection cavity into a clamping position, in which the electrical conductor can be clamped in the conductor connection cavity by means of the clamping element. Wherein, the clamping element can be pushed into the clamping position by the manipulation element.

[0009] Thus, different from previously known solutions, the clamping element does not need to be pre-tensioned to the clamping position. In this way, force can be applied in other ways, for example, by means of an independent spring. Since the actuating element pushes the clamping element into the clamping position, this force can be applied to the actuating element. In this way, the available structural space can be divided more freely.

[0010] Wherein, the clamping element can be free of force in the release position. Thereby, the clamping element is reliably held in the release position. In addition, in this way, the clamping element can be held in the release position by simple means. Thereby, the tripping mechanism for moving the clamping element from the release position into the clamping position can adopt a particularly simple structure.

[0011] The actuating element can have an actuating area that can be contacted by hand and / or with the aid of tools at the opening of the housing. In this way, the user can simply adjust the actuating element (from the outside).

[0012] For example, the actuating element can be locked in a holding position that holds the clamping element in the release position. In this way, a firm lock can be achieved.

[0013] In the holding position, the actuating element can be locked with the locking element of the housing, for example. Thereby, a simple structure and a particularly firm lock are achieved.

[0014] The actuating element can have a hook that is locked with the locking element of the housing in the holding position. Thereby, a reliable and easily releasable lock is achieved.

[0015] Optionally, the holding position of the actuating element can be unlocked by a tripping element supported in a manner that can move relative to the housing, for example. Thereby, a particularly simple and reliable unlocking is achieved.

[0016] The tripping element can have an unlocking ramp. The following solution can be adopted: the unlocking ramp can slide along the hook of the actuating element, so that the hook is disengaged from the locking with the locking element of the housing. In this way, the lock can be released with a small force and there will be no jamming.

[0017] In a construction scheme, the tripping element can be contacted by an electrical conductor inserted into the conductor connection cavity, and / or can move relative to the housing. In this way, unlocking can be achieved particularly simply by inserting the electrical conductor into the conductor connection cavity.

[0018] Optionally, the tripping element is supported on the housing by a spring. This simplifies the reset of the tripping element.

[0019] The connecting device may include a spring element. The spring element may be arranged in such a way as to apply a force to the actuating element. In particular, the spring element may be arranged such that it pre-tensions the actuating element to a contact position which pushes the clamping element into the clamping position. This enables intuitive operation, since the actuating element can apply a force to the clamping element in two directions and thereby influence the position of the clamping element.

[0020] Optionally, the spring element is constructed in the form of a helical spring. This enables the use of standard components. That is, there is no need to manufacture a spring element with a complex form. In addition, by using a helical spring, a very precisely defined spring force can be achieved and it can be easily adjusted according to different applications.

[0021] According to one construction variant, the actuating element is supported movably on the housing. This enables tripping by means of a linear movement.

[0022] Optionally, the actuating element engages with the clamping element. The actuating element has, for example, a rear catch which catches the clamping element from behind. That is, the actuating element has material sections, for example, on opposite sides of the clamping element. Thereby, the actuating element can move the clamping element in opposite directions.

[0023] The clamping element may be supported in a deflectable manner, for example, on a shaft of the housing. Optionally, the clamping element is rigid. The following variant can be employed: during the deflecting movement of the clamping element around the shaft, the sections of the clamping element do not deform. This enables a particularly large clamping force to be applied to the electrical conductor.

[0024] The electrical conductor can be clamped, for example, by the clamping element against a contact element (for example, in the form of a current bar for connection to other electrical components) in a conductor connection cavity, so as to make electrical contact with the contact element. As an alternative or in addition, several individual electrical conductors can be inserted into a wiring configuration, thereby electrically connecting these conductors to each other.

DETAILED DESCRIPTION

[0038] Figures 1A - 5B A connecting device 1A is shown, which enables an electrical connection of an electrical conductor 2 to a contact element 11.

[0039] The connecting device 1 includes a housing 10A, a contact element 11, a clamping element 12, an actuating element 13, a tripping element 14A, and a spring element 15 in the form of a helical spring (more precisely, in the form of a helical compression spring) in this case.

[0040] A socket 104 is constructed on the housing 10A, into which the electrical conductor 2 can be inserted in the insertion direction E (for example, seeFigure 1A and Figure 3A )。The housing 10A defines an inner cavity, which is herein referred to as the conductor connection cavity 100 and is configured in the form of a chamber. The electrical conductor 2 can be inserted into the conductor connection cavity 100 with its (insulation-stripped) end 20 by inserting the socket 104, so that the electrical conductor makes electrical contact with the contact element 11 provided in the housing 10A within the conductor connection cavity 100. Thus, the conductor connection cavity 100 is accessible from the outside through the socket 104. The housing 10A is made of an insulating material, for example, made of plastic.

[0041] The housing 10A has a base body. The base body is integrally constructed. In the assembled state, the base body is (optionally) closed by a cover part 108 as shown and described in detail below. As an alternative, for example, several such connection devices 1A can be installed side by side. Figure 9C shown and will be described in detail below. As an alternative, for example, several such connection devices 1A can be installed side by side.

[0042] The contact element 11 is configured in the form of a current bar. The contact element 11 extends along a wall portion of the housing 10A and extends on the bottom side here. The contact element 11 serves as an energized component. The contact element 11 optionally includes a connection section led out from the housing 10A, and the connection section is used to establish an electrical connection with another component (such as a connection device constructed in a similar manner). Through the contact element 11, the electrical conductor 2 inserted into the conductor connection cavity 100 can be electrically connected to other components. As an alternative, the contact element 11 is completely arranged inside the housing 10A and is used, for example, to electrically connect two or more electrical conductors 2 inserted into the conductor connection cavity 100 to each other. The contact element 11 extends parallel to the insertion direction E. The contact element 11 is flat. The contact element 11 is integrally constructed.

[0043] The housing 10A also has a shaft 101 for the clamping element 12 and a guide 102 for the actuating element 13.

[0044] In order to reliably make the inserted electrical conductor 2 electrically contact with the contact element 11, the connection device 1A includes a clamping element 12 that can be moved from a clamping position to a release position. In the clamping position, the electrical conductor 2 can be clamped against the contact element 11 by the clamping element 12 in the conductor connection cavity 100. In the release position, the conductor connection cavity 100 and the electrical conductor 2 provided in the conductor connection cavity 100 are released, so the electrical conductor 2 can be taken out. In the release position, the electrical conductor 2 can also be inserted into the conductor connection cavity 100 without pushing the electrical conductor 2 against a component.

[0045] In Figures 8A to 8CThe clamping element 12 is shown separately therein. The clamping element 12 is made of a conductive material, for example, made of a metal or a metal alloy, but this is not necessary. Here, the clamping element 12 is integrally constructed, for example, manufactured by stamping and bending a flat material. The clamping element 12 includes a flat section, at the free end of which an edge serves as a clamping edge 120. In the clamping position of the clamping element 12, the clamping edge 120 is pressed against the contact element 11 or against the electrical conductor 2 provided in the conductor connection cavity 100. If the electrical conductor 2 is inserted into the socket 104, or if the electrical conductor has already been inserted into the socket, the clamping edge 120 of the clamping element 12 acts on the electrical conductor 2 in such a way in the clamping position that the electrical conductor 2 is mechanically locked and also makes electrical contact with the contact element 11.

[0046] The clamping element 12 has rigidity. The clamping element does not bend or only bends slightly due to the forces acting in the connecting device 1A.

[0047] The clamping element 12 has a suspension portion 121. Here, the suspension portion 121 is formed by a ring-shaped bent section of the clamping element 12. The suspension portion 121 is adjacent to the flat section and is located at the end opposite to the clamping edge 120 here. The suspension portion 121 loops around the shaft 101 of the housing 10A. The suspension portion 121 and the shaft 101 together form a rotary bearing. Among them, the clamping element 12 is deflectable relative to the housing 10A about a deflection axis S (see Figure 1A ).

[0048] The clamping element 12 also has a notch 122 (see Figures 8A to 8C ). The notch 122 is constructed in the form of a side recess here. The clamping element 12 engages with the operating element 13. For this purpose, the operating element 13 has a rear gripping portion 133, which loops around the clamping element 12. Here, the rear gripping portion 133 loops around the clamping element 12 at the notch 122.

[0049] In Figures 7A to 7C the operating element 13 is shown separately. The operating element 13 is integrally constructed. The operating element 13 has a slider 131, which is supported in such a way that it can move in the aforementioned guide 102 of the housing 10A and is in a straight line form here. For example, it can be seen from Figure 1A that the operating element 13 is supported in such a way that it can move on the housing 10A in a direction parallel to the insertion direction E. For this purpose, in the shown example, the slider 131 has groove-shaped protrusions on the opposite sides, which slide along the guide 102. The guide 102 is bounded by a stop in one direction. The groove-shaped protrusions abut against the shown stop. These stops are formed by longitudinally extending ribs, which form a receiving portion for a spring element 15 that will be explained in detail below.

[0050] The actuating element 13 also has an actuating area 132. The actuating area 132 is formed by the end of a section extending from the slide 131. The actuating area 132 projects from the housing 10A in at least one position of the actuating element 13 relative to the housing 10A, and in so doing passes through an opening 107 in the outer wall of the housing 10A. The actuating area 132 can be manually actuated by the user, and in so doing can be pressed by the user. The actuating area 132 also has a slot into which a tool, in particular a screwdriver, can be inserted to actuate the actuating element 13. Since the actuating element 13 can be pressed via the actuating area 132, the actuating element can also be referred to as a pusher.

[0051] On the side of the slide 131 opposite the actuating section 132, the actuating element 13 has a bolt 136. In the assembled state, the spring element 15 is plugged onto the bolt 136. The end of the spring element 15 is securely held on the bolt 136.

[0052] The spring element {15} is configured in the form of a helical spring. The spring element 15 is supported on the actuating element 13 by means of one of two mutually facing ends, and is supported on the wall 103 of the housing 10A by means of the other of these two ends (see for example Figure 1A ). The spring element 15 exerts a pressure on the actuating element 13. In so doing, the spring element 15 presses the actuating area 132 out through the opening 107 of the housing 10A. Actuating the actuating element 13 by pressing the actuating area 132 counteracts the force of the spring element 15.

[0053] The actuating element 13 also has a hook 130. The hook 130 serves as a catch. The hook 130 is constructed at the end of an arm 135 of the actuating element 13. The arm 135 extends parallel to the axis, and the actuating element 13 is supported on the housing 10A in such a way that it can move along said axis. The arm 135 extends parallel to the insertion direction E. The arm 135 is connected to the slide 131 by means of a connecting section, and in so doing is connected at its end facing away from the hook 130. The aforementioned rear holding section 133 extends from said connecting section in the opposite direction. The arm 135 and the rear holding section 133 are arranged below the slide 131. The rear holding section 133 has two mutually perpendicular areas. The actuating element 13 has an edge 134 adjacent to the rear holding section 133. Depending on the position of the actuating element 13, the rear holding section 133 and / or the edge 134 come into contact with the clamping element 12.

[0054] The hook 130 has an insertion bevel. Generally speaking, the housing 10A has at least one locking element 105. Here, the housing 10A is on a base body (see Figure 9A and Figure 9B ) and on the cover 108 (see Figure 9C)Each has a locking element 105 thereon. Each of the locking elements 105 has an insertion ramp and can be latched from behind by the hook 130. In the assembled state, the two locking elements 105 abut against each other and thereby jointly form a coherent locking element, thus enhancing stability. However, only one locking element 105 can also be provided on the base body or on the cover part 108.

[0055] The actuating element 13 can be locked to the locking element 105 by means of the hook 130, which will be described in detail below.

[0056] In order to release the locking of the hook 130 and the locking element 105, the connecting device 1A has a tripping element 14A.

[0057] Figures 6A to 6C The tripping element 14A is shown separately. The tripping element 14A has a cuboid-shaped body on which two ramps extending towards each other are constructed, and these ramps are in the form of inclined planes. The steeper and shorter of these ramps is hereinafter referred to as the locking ramp 140. The other ramp is hereinafter referred to as the unlocking ramp 141. The two ramps cooperate with the hook 130 of the actuating element 13.

[0058] The tripping element 14A also has guides 142, which are located on opposite sides here and are in the form of elongated recesses in the illustrated example. In the assembled state, the pins 106 are snapped into the guides 142 on the base body of the housing 10A and on the cover part 108. The tripping element 14A is supported in a movable (here linearly movable) manner in the housing 10A. The length of the guides 142 limits the movement distance of the tripping element 14A relative to the housing 10A. Therefore, in this direction, the movement distance of the tripping element 14A is shorter than that of the tripping element 14A.

[0059] The tripping element 14A can move (more precisely, move) between a first position and a second position. The tripping element 14A is closer to the socket 104 in the first position than in the second position.

[0060] The following will be combined with Figures 1A to 5B to explain the function of the connecting device 1A. In order to view the inside of the connecting device 1A, the cover part 108 is removed. Figures 1A - 5A Respectively, a top view of the connecting device 1A, Figures 1B - 5B is a perspective view.

[0061] Figure 1A and Figure 1BThe connecting device 1A is shown in an initial state (e.g., the delivery state). In this state, the electrical conductor 2 is not yet connected. The hook 130 is unlocked from the locking element 105. The actuating element 13 is pushed by the force of the spring element 15 into a contact position, which pushes the clamping element 12 into a clamping position. The clamping element 12 comes into contact with the contact element 11 by means of the clamping edge 120. The release element 14A is in the second position. The actuating region 132 of the actuating element 13 projects from the housing 10A. In this way, the user can clearly identify that the clamping element 12 is in the clamping position.

[0062] To connect the electrical conductor 2, the actuating region 132 is actuated. In this case, the rear gripping part 133 of the actuating element 13 drives the clamping element 12, and this clamping element pivots about the pivot axis S. In addition, the hook 130 slides in this case along the locking ramp 140 of the release element 14A, wherein the arm part 135 bends elastically. Subsequently, the hook 130 latches behind the locking element 105 of the housing 10A. In this case, the unlocking ramp 141 slides along the hook 130, wherein the release element 14A moves into the first position. In this case, the hook 130 latches behind the locking element 105. In this way, the actuating element 13 is locked on the housing 10A and is locked in the holding position. In the holding position, the actuating element 13 holds the clamping element 12 in its released position. Compared with Figure 1A and Figure 1B the position shown, the actuating region 132 is moved further into the housing 10A and is completely arranged in the housing 10A here.

[0063] Figure 2A and Figure 2B show this position. This position can also be referred to as the tensioned position. In this case, the user can clearly identify that the clamping element 12 is in the released position and the electrical conductor 2 can be connected. In the released position, the clamping element 12 is not stressed. None of the remaining components of the connecting device 1A exerts a force on the clamping element 12.

[0064] Figure 3A and Figure 3B show the start of the connection of the electrical conductor 2. In this case, the electrical conductor 2 is inserted into the conductor connection cavity 100 through the socket 104. The end 20 of the electrical conductor 2 comes into contact with the release element 14A. If the electrical conductor 2 is inserted further, the electrical conductor pushes the release element 14A from the Figure 3A and Figure 3B shown first position into the second position.

[0065] As Figure 4A and Figure 4BAs shown, the release element 14A has been further moved to the second position, where the unlocking ramp 141 of the release element 14A slides along the hook 130 of the actuating element 13 and presses against this hook (pressing upward in Figure 4A ). In this case, the arm 135 bends elastically. This lifts the hook 130 out of its locking engagement with the locking element 105.

[0066] Once the locking engagement of the hook 130 with the locking element 105 is released, the actuating element 13 is immediately pushed by the force of the spring element 15 into the contact position. In this case, the edge 134 of the actuating element 13 presses the clamping element 12 against the electrical conductor 2 into the clamping position. In this case, the electrical conductor 2 is clamped against the contact element 11. During the movement of the actuating element 13, the release element 14A is also carried along to a certain extent. That is, the clamping element 12 can be supported in a manner movable relative to the housing 10A and the actuating element 13 acting in connection with the clamping element 12 is pushed into the clamping position. The user can clearly recognize that the clamping element 12 is in the clamping position. By using a spring element 15 in the form of a helical spring, a relatively large clamping force can be achieved.

[0067] Figures 10A to 1E A connecting device 1B is shown, the structure and function of which are basically the same as those of the connecting device as Figures 1A - 5B shown.

[0068] Therein, a spring 143 in the form of a helical spring is provided, which pushes the release element 14B into the first position. Thereby, the spring 143 simplifies the movement of the release element 14B from the second position to the first position.

[0069] Therein, in particular as Figures 12A to 12C shown, the release element 14B is provided with a bolt 145. In the assembled state, one end of the spring 143 surrounds the bolt 145. The other end of the spring 143 surrounds the bolt 109 of the housing 10B. In Figure 11A and Figure 11B the bolt 109 of the housing 10B can be seen in particular. The spring 143 is much smaller than the spring element 15.

[0070] Figures 13A to 13C Another release element 14C is shown. This release element 14C has a spring 144, which is integrally connected to the release element 14C. In this case, the spring consists of a bent elastic section of the release element 14C. This spring 144 bears against the widened section B of the wall 103 of the housing 10C (for example, see Figure 14A ).

[0071] In the initial state (see Figure 10A or Figure 14A) Under this condition, springs 143; 144 push the release elements 14B; 14C towards the hook 130 of the actuating element 13. Once the hook 130 is locked in the tensioned state due to the actuation of the actuating element 13, the springs 143; 144 immediately push the release elements 14B; 14C into the first position (refer to Figure 10B or Figure 14B ). If the electrical conductor 2 is inserted (refer to Figure 10C or Figure 14C ) and the release elements 14B; 14C are pushed back into the second position (refer to Figure 10D or Figure 14D ), the hook 130 is unlocked, and the springs 143; 144 then assist the release elements 14B; 14C to move back to the first position (refer to Figure 10E or Figure 14E ).
