Description

Connecting assembly, wiring terminal and electronic equipment
Technical Field
The invention relates to a connection assembly for connecting electrical conductors. Furthermore, the invention relates to a terminal and an electronic device having such a connecting assembly.
Background
Such a connection assembly is used to connect one or more conductors. The connecting assembly has one conductor connecting element for each conductor to be connected, so that the connecting assembly can have more than one conductor connecting element. Such a conductor connection element may have, for example, a clamping spring in the form of a clamping arm spring having a holding arm and a clamping arm, wherein a conductor inserted into the connection assembly can be clamped to the current bar by means of the clamping arm of the clamping spring. If, in particular, a flexible conductor is clamped, the clamping spring has to be moved into the open position by means of an actuating element before the conductor is introduced and is thus actuated in order to pivot the clamping spring or the clamping arm away from the current bar, so that the conductor can be introduced into the intermediate space between the current bar and the clamping spring. Only in the case of a rigid and therefore stable conductor can the conductor exert sufficient force on the clamping spring or the clamping arm of the clamping spring in order to be able to pivot the clamping arm away from the current bar without the actuating element having to be actuated by the user for this purpose. In the case of a flexible conductor, the user must first pivot the clamping spring away from the current bar by actuating the actuating element in order to be able to insert the flexible conductor. In order to clamp the inserted conductor, the actuating element must again be manually actuated by the user in order to move the clamping spring from the open position into the clamping position. The actuation of the actuating element by the user makes it difficult for the user to install or connect the line, since the actuation is complicated and therefore also increases the time consumption. Furthermore, different connection techniques may be suitable for the conductors, depending on requirements.
Disclosure of Invention
The invention aims to provide a connecting assembly, a connecting terminal and an electronic device, wherein the flexibility in connecting electric conductors can be improved.
According to the invention, this object is solved with the features of the independent claims. Advantageous embodiments and advantageous refinements of the invention are specified in the dependent claims.
The connecting assembly according to the invention has a first conductor connecting element for connecting a first electrical conductor and a second conductor connecting element for connecting a second electrical conductor, wherein the first conductor connecting element has a connection technology to a current bar, which has: a clamping spring with a clamping arm that is displaceable into a clamping position and an open position; a conductor connection chamber formed between a section of the current bar and the clamping arm of the clamping spring; a movably arranged clamping element, which is operatively connected to a clamping arm of the clamping spring, wherein the clamping arm can be held in a release position by means of the clamping element; and a trigger element which engages with the clamping element in a release position of the clamping arm of the clamping spring, wherein the trigger element can be actuated by the conductor when the conductor to be connected is introduced into the conductor connection space such that the trigger element is disengaged from the clamping element, and the clamping element can be moved by the spring force of the clamping arm such that the clamping arm can be transferred into a clamping position for clamping the conductor relative to the current bar. The second conductor connecting element has a connecting technology which is configured differently from the first conductor connecting element.
In the solution according to the invention, it is now possible, in particular with the first conductor connecting element, without manual actuation of the actuating element, to also connect the flexible conductor and clamp it on the current bar or on the current bar section of the current bar. The clamping spring is preferably configured as a clamping arm spring having a holding arm and a clamping arm configured to be pivotable relative to the holding arm. By means of a pivoting movement of the clamping arm, the clamping arm can be transferred into a release position, in which the clamping arm is arranged at a distance from the current bar and a conductor to be connected can be introduced into or can be discharged from a conductor connection chamber formed between the current bar and the clamping arm, and into a clamping position, in which the clamping arm can be brought into contact with the current bar or a connected conductor in order to clamp the conductor relative to the current bar. The first conductor connecting element has a clamping element which is mounted in a particularly horizontally displaceable manner and which is preferably operatively connected to the clamping spring both in the open position and in the clamping position of the clamping arms of the clamping spring, which means that the clamping arms follow the sliding movement of the clamping element and thus the position of the clamping element by being operatively connected to the clamping element. The clamping element holds the clamping arm in the release position against its spring force by the clamping element pressing against the clamping arm. In order to be able to hold the clamping element in this position, the clamping element engages with the triggering element in the release position of the clamping arm of the clamping spring. If the triggering element engages with the clamping element, a sliding movement of the clamping element is not possible or is stopped. By virtue of the effective connection or coupling of the trigger element to the clamping element and the effective connection or coupling of the clamping element to the clamping arm of the clamping spring in the open position of the clamping arm, the clamping arm can be held in this open position without additional manual actuation, so that in particular a flexible conductor can be introduced into the conductor connection chamber between the current bar and the clamping spring which is thus free. The trigger element can have a pressure surface pointing in the direction of the conductor connection chamber, which pressure surface is arranged aligned with the lead-in region of the conductor inserted into the first conductor connection element or aligned with the conductor connection chamber, so that the conductor, when inserted into the first conductor connection element, strikes the pressure surface of the trigger element, whereby a pressure can be exerted by the conductor on the trigger element. By applying a pressure force to the pressure surface and thus to the trigger element by means of the conductor, the trigger element can be set in a pivoting or tilting movement in the direction of insertion of the conductor, for example, so that the trigger element can be pivoted or tilted away from the clamping element in the direction of insertion of the conductor. By means of the pivoting movement of the trigger element, the trigger element can be disengaged from the clamping element, so that the clamping element can be moved freely again, and the clamping element can thus be moved without manual assistance only by the spring force of the clamping arm, in such a way that the clamping arm can be transferred from the release position into the clamping position. By means of this special mechanism, it is possible to connect the flexible conductor particularly simply by a lead-in movement of the conductor, without the user having to actuate further elements, for example an actuating element, in order to release the clamping spring and transfer it from the release position into the clamping position. This makes the handling of the first conductor connection element and thus of the connection assembly easier and saves time when connecting the conductors. The triggering element is preferably an element or component which is constructed separately from the clamping spring, the current bar and the clamping element. The trigger element preferably extends over a region of the current bar between the section of the current bar, against which clamping of the conductor is possible, and the clamping spring, so that the trigger element can delimit the conductor connection chamber towards one side. The clamping element may be configured as a sliding element.
In order to be able to form an effective connection between the clamping element and the clamping arm of the clamping spring, it can be provided that the clamping element has at least one spring contact edge against which the clamping arm can be brought into contact. The spring contact edge can be designed such that the clamping arm or at least a part of the clamping arm can rest against the spring contact edge both in the release position and in the clamping position. The spring contact edge can be formed, for example, on a shoulder of the clamping element.
In order to be able to achieve a uniform guidance of the clamping element and of the clamping arms of the clamping spring, two such spring contact edges can be formed on the clamping element, so that the clamping arms can be guided on the clamping element by means of the two such spring contact edges. The two spring contact edges preferably extend parallel to one another on the clamping element.
In this embodiment, the clamping arm can have two sliding sections which are each arranged laterally to the main section with the clamping edge, and the clamping element can have two spring contact edges which are arranged at a distance from one another, wherein the first sliding section can bear against the first spring contact edge and the second sliding section can bear against the second spring contact edge. The two sliding sections preferably each have a shorter length than the main section of the clamping arm. The main section and the two sliding sections preferably extend parallel to each other. The two sliding sections are preferably each formed in a curved manner, so that they can each form a sliding plate, which can each slide along the spring contact edge. In contrast, the main section is preferably straight.
The clamping element is preferably movable such that a sliding movement of the clamping element can be carried out transversely to the direction of introduction of the conductor to be connected into the conductor connection chamber. As a result, a particularly compact design can be achieved, whereby the connecting assembly can be characterized by a reduced installation space.
In order to be able to release the triggering element from the clamping element and thus to be able to disengage it from the clamping element by means of a conductor introduced into the conductor connection chamber, the triggering element can be mounted so as to be tiltable relative to the clamping element. The trigger element can thus be constructed in a see-saw manner. If the conductor to be connected is pushed against the triggering element, the triggering element can be tilted in the direction of introduction of the conductor in order to disengage the clamping element, so that the clamping element is released, so that the clamping element can be freely moved again.
In order to be able to engage the trigger element with the clamping element in the release position of the clamping arm of the clamping spring, the trigger element can have at least one undercut which can be latched with at least one latching projection of the clamping element in the release position of the clamping arm of the clamping spring. In this way, a latching connection can be formed between the clamping element and the triggering element when the clamping arm of the clamping spring is in the release position. Preferably, the trigger element has two undercuts and the clamping element preferably has two latching projections, so that a double-acting latch can be formed between the clamping element and the trigger element. If two undercuts are provided, they are preferably formed on two mutually parallel sides of the triggering element.
Preferably, it can also be provided that the clamping element has two longitudinal side walls arranged parallel to one another, which define a conductor connection chamber on a first side and a second side opposite the first side. The clamping element can thus also constitute a guide for the conductor to be connected when it is introduced into the conductor connection chamber. The two longitudinal side walls can prevent the conductors from being inserted wrongly. The conductor connection chamber can thus be delimited on its two sides by the clamping element and on its other two sides by the current bar and the clamping arms of the clamping spring.
The connecting assembly can also have an actuating element, by means of which the clamping element can be moved for moving the clamping arm of the clamping spring from the clamping position into the release position. The actuating element can preferably be designed such that it exerts a pressure force on the clamping element in order to move the clamping element against the spring force of the clamping arm of the clamping spring in such a way that the clamping element can be brought into engagement with the trigger element when the release position of the clamping arm is reached. By means of the sliding movement, the clamping element can exert a tensile force on the clamping arm of the clamping spring in order to transfer the clamping arm from the clamping position into the release position. Preferably, the actuating element is movable in a direction oriented transversely to the sliding movement direction of the clamping element. The actuating element is preferably movable purely translationally. The direction of movement of the actuating element is preferably oriented parallel to the direction of introduction of the conductor into the conductor connection chamber.
The clamping element can have a sliding surface along which the actuating element can be guided. On the sliding surface, the actuating element can bear flat against the clamping element. The actuating element can slide along the clamping element via a sliding surface and thereby transmit a pressure force to the clamping element.
The sliding surface can be arranged between two longitudinal side walls of the clamping element or on an end wall of the clamping element. The sliding surface is preferably oriented in such a way that it extends transversely to the two longitudinal side walls. By providing a sliding surface between the two longitudinal side walls, the actuating element can be inserted for actuating the clamping element into a cavity defined by the two longitudinal side walls and the sliding surface, wherein the two longitudinal side walls can form a guide aid for the actuating element, so that the actuating element can be prevented from tilting when guided along the sliding surface of the clamping element.
The sliding surface can form a ramp surface which can interact with a ramp surface formed on the actuating element. If the sliding surface is designed as a ramp, the ramp preferably has a slope. The surface of the actuating element which bears against the sliding surface is then preferably also designed as a ramp, which is designed obliquely to the longitudinal extent of the actuating element which extends in the direction of movement of the actuating element. If both the sliding surface and the surface of the actuating element along which the sliding surface slides are designed as inclined surfaces, the vertical movement direction of the actuating element can be converted into a horizontal sliding movement of the clamping element when the actuating element slides along the sliding surface.
The actuating element is preferably arranged such that it does not project into the conductor connection chamber, so that interaction of the actuating element with the connected conductor is prevented. Preferably, the clamping spring, the current bar and the actuating element are arranged such that the clamping spring is arranged between a section of the current bar, against which the conductor to be connected is clamped, and the actuating element.
The second conductor connecting element differs from the first conductor connecting element in that the second conductor connecting element has a different connection technology than the first conductor connecting element. The connecting assembly can thus have and provide two different connecting techniques, so that different types of conductors can be connected, for example, with the connecting assembly. For example, a first conductor connection element may enable connection of a flexible conductor with the outer jacket removed or the insulation removed, while a second conductor connection element may enable connection of a rigid conductor with the outer jacket removed or the insulation removed. Furthermore, the second conductor connection element can also be designed such that it enables the connection of conductors without jacket removal or insulation removal.
The second conductor connection element preferably has no triggering element, which can be actuated by the conductor to be connected. The second conductor connecting element also preferably has no corresponding clamping element, which can interact with the clamping spring and the triggering element. The second conductor connecting element therefore preferably has no triggering element and/or clamping element corresponding to the first conductor connecting element.
The second conductor connecting element preferably has an actuating element, by means of which the clamping arm of the clamping spring of the second conductor connecting element can be moved from the clamping position into the open position and from the open position into the clamping position. The second conductor connection element preferably has a clamping spring and a current bar, wherein the conductor to be connected can be clamped in an electrically conductive manner against the current bar. The actuating element is preferably arranged between the current bar and the clamping spring.
The actuating element of the second conductor connecting element can be designed such that it can execute a purely linear movement or a purely translational movement for displacing the clamping arms into the open position and into the clamping position. However, the actuating element of the second conductor connecting element can also be pivotably supported. The actuating element can then have the shape of an actuating lever.
The second conductor connecting element can have a clamping spring in the form of a clamping arm spring having a holding arm and a clamping arm, wherein the holding arm and the clamping arm can be connected to one another by means of an arc-shaped section. However, the clamping spring of the second conductor connection element can also be designed in the form of a tension spring, wherein the clamping arm has a window-like opening through which the holding arm of the clamping spring passes.
Furthermore, the second conductor connection element may not have a spring-loaded clamping connection with a clamping spring, but rather is designed in the form of a screw connection element.
Furthermore, the second conductor connection element can also be designed in the form of a cutting connection element, wherein the conductor to be connected is pressed into the cutting element, whereby the insulation or the jacket of the conductor is cut open, so that an electrical contact can be made between the strand or core of the conductor and the cutting element. Thus, the conductor may be connected without stripping the insulation or without stripping the jacket.
Depending on the installation space and the available space, it can also be advantageous if the connection of the conductors can take place from different directions. For example, the first conductor connection element can have a conductor connection chamber into which a first conductor to be connected can be inserted along a first insertion direction, while the second conductor connection element can have a conductor connection chamber into which a second conductor to be connected can be inserted along a second insertion direction, wherein the second conductor connection chamber can be oriented relative to the first conductor connection chamber in such a way that the second insertion direction is designed to be rotated by 90 ° relative to the first insertion direction.
The object is also achieved according to the invention by means of a terminal having a housing and at least one connecting assembly arranged in the housing, wherein the at least one connecting assembly can be constructed and improved as described above. The housing preferably has latching feet, by means of which the housing and thus the connecting terminal can be latched to the support rail. The housing is preferably made of an insulating material, such as plastic. The connection terminal can have, for example, a test plug opening or an opening for connecting a transverse bridge element or other functional components. The current bar of the first conductor connecting element can be formed integrally with the current bar of the second conductor connecting element.
The solution according to the object of the invention can furthermore be achieved by means of an electronic device which can have at least one connecting assembly constructed and improved as described above and/or at least one connecting terminal constructed and improved as described above.

Detailed Description
Fig. 1 to 7 each show a connecting terminal 200 with a housing 210, which can be made of an insulating material, wherein a connecting assembly for connecting two conductors, not shown here, is arranged or accommodated in the housing 210. Each connecting assembly 100 of the connecting terminal 200 shown in fig. 1 to 7 has a first conductor connecting element a for connecting a first electrical conductor and a second conductor connecting element B for connecting a second electrical conductor. The connection means or the connection technology of the two conductor connecting elements A, B of the connecting terminal 200 are respectively different, so that in each of the connecting terminals 200 shown here, the connection of the two incoming conductors in the respective connecting terminal 200 takes place in different ways and methods, so that different types of conductors can also be connected to one connecting terminal 200.
The first conductor connecting elements a of the connecting terminals 200 shown in fig. 1 to 7 are each identically designed.
The first conductor connection element a has a current bar 110 and a clamping spring 111 configured as a clamping arm spring. The clamping spring 111 has a holding arm 112 and a clamping arm 113. The retaining arm 112 is held in a fixed position, while the clamping arm 113 can pivot relative to the retaining arm 112. By means of a pivoting movement of the clamping arm 113, it can be transferred into a clamping position, as shown for example in fig. 1, and into an open position, as shown for example in fig. 2. In the clamping position, the clamping arm 113 is pressed against a section of the current bar 110 or against the first conductor inserted into the second conductor connecting element a in order to clamp and connect it relative to this section of the current bar 110. In the open position, the clamping arm 113 is positioned at a distance from the section of the current bar 110, so that a conductor can be introduced into the cavity formed thereby between the section of the current bar 110 and the clamping arm 113.
Furthermore, the first conductor connection element a has a clamping element 115. The clamping element 115 is mounted in particular so as to be movable relative to the current bar 110, so that the clamping element 115 can execute a horizontal sliding movement V.
The clamping arms 113 of the clamping spring 111 can be transferred from the clamping position into the open position and held in the release position by means of the clamping element 115. For this purpose, the clamping element 115 is operatively connected to the clamping arm 113 of the clamping spring 111.
In the embodiment shown here, the clamping element 115 has two spring contact edges 116 arranged parallel to one another, against which the clamping arms 113 contact.
The clamping arm 113 has a main section, at the free end of which a clamping edge is formed. On the side of the main section, two sliding sections 119 are formed such that the main section is located between the two sliding sections 119. The two sliding sections 119 bear against the two spring contact edges 116 of the clamping element 115, wherein the first sliding section 119 bears against the first spring contact edge 116 and the second sliding section 119 bears against the second spring contact edge 116. The sliding section 119 rests against the spring contact edge 116 both in the release position and in the clamping position of the clamping arm 113 of the clamping spring 111.
The sliding section 119 has a shorter length than the main section. The sliding portions 119 are designed to be curved, so that they are designed in the form of a sliding plate, by means of which the sliding portions 119 can slide along the spring contact edge 116 when the clamping arm 113 is transferred into the release position and into the clamping position, as can be seen in particular in fig. 1 and 2.
The two spring contact edges 116 are formed on opposite longitudinal side walls 120 of the clamping element 115. The two longitudinal side walls 120 are arranged parallel to each other. The two longitudinal side walls 120 each have an upper edge and an opposite lower edge. The spring contact edges 116 each extend perpendicularly to the upper edge 121. The spring contact edge 116 extends from the horizontally extending upper edge downward in the direction of the horizontally extending lower edge of the clamping element 115.
The current bar 110 and the clamping spring 111 are arranged between two longitudinal side walls 120 of the clamping element 115. The current bar 110 and the clamping spring 111 are surrounded by a clamping element 115.
Furthermore, the clamping element 115 has two end walls, which are oriented parallel to one another. Which are arranged transversely to the two longitudinal side walls 120 of the clamping element 115.
A conductor connection chamber 124 is formed between the section 114 of the current bar 110 and the clamping arm 113, into which conductor connection chamber 124 a conductor to be connected can be introduced. The conductor connection chamber 124 is laterally covered or delimited by two longitudinal side walls 120 of the clamping element 115, so that the clamping element 115 also constitutes a guide for the conductor to be connected.
The conductor connection chamber 124 is formed in alignment with a conductor insertion opening 211 formed in the housing 210, through which a conductor to be connected can be inserted into the housing 210 of the connection terminal 200.
The first conductor connection element a also has a triggering element 125. The trigger element 125 is arranged in alignment with the conductor introduction opening 211 and the conductor connection chamber 124. The trigger element 125 downwardly defines a conductor connection chamber 124.
In the open position of the clamping arm 113 of the clamping spring 111, the trigger element 125 engages with the clamping element 115, as can be seen, for example, in fig. 2, as a result of which the clamping element 115 is held in its position and is thus also held in its position by the spring contact edge 116 and the sliding section 119 of the clamping arm 113, so that an undesired pivoting back of the clamping arm 113 from the open position into the clamping position can be prevented.
The trigger element 125 has two laterally arranged undercuts which, in the open position of the clamping arms 113 of the clamping spring 111, engage in each case one latching projection 127 of the clamping element 115 in order to form a latching between the clamping element 115 and the trigger element 125. Such a latching projection 127 is formed on each of the two longitudinal side walls 120.
In the clamping position, the triggering element 125 is disengaged from the clamping element 115, as can be seen in fig. 1, so that the clamping element 115 can move freely.
The triggering element 125 is supported in a tiltable manner relative to the clamping element 115.
In the direction of introduction E of the conductors to be connected1When the conductor is introduced into the conductor connection chamber 124 via the conductor introduction opening 211, the conductor touches the trigger element 125, as a result of which the trigger element 125 is tilted relative to the clamping element 115 and is thereby disengaged from the clamping element 115, so that the clamping element 115 can be freely moved again and thus the clamping element 115 can be moved without manual assistance only by the spring force of the clamping arm 113 in such a way that the clamping arm 113 can be transferred from the open position into the clamping position. The trigger element 125 has a pressure surface pointing in the direction of the conductor connection chamber 124, which is arranged in alignment with the conductor insertion opening 211 or in alignment with the conductor connection chamber 124, so that the conductor, when being inserted into the first conductor connection element a, strikes against the pressure surface of the trigger element 125, whereby the conductor exerts a pressure forceOnto the trigger element 125. By applying pressure to the pressure surface and thus to the triggering element 125 by means of the conductor, the triggering element 125 can be placed in the lead-in direction E of the conductor1So that the triggering element 125 can be moved in the direction of introduction E of the conductor1Pivoting or tilting away from the clamping element 115.
When the clamping element 115 is disengaged from the triggering element 125, the sliding movement V of the clamping element 115 is transverse to the direction of introduction E of the conductor to be connected into the conductor connection chamber 1241The direction of orientation.
In order to return the clamping arm 113 from the clamping position into the release position counter to its spring force by means of the clamping element 115, the first conductor connecting element a has an actuating element 129. The actuating element 129 can be moved in an actuating direction B1Movably supported, wherein the direction B is manipulated1Parallel to the lead-in direction E of the conductor1. Steering direction B1Extending transversely to the sliding movement V of the clamping element 115.
By means of the actuating element 129, the clamping element 115 can be displaced such that the clamping arm 113 of the clamping spring 111 abutting against the clamping element 115 can be transferred from the clamping position into the open position. In the steering direction B1When actuating the actuating element 129, the actuating element 129 can be moved such that it exerts a pressure force on the clamping element 115 in order to move the clamping element 115 against the spring force of the clamping arm 113 of the clamping spring 115, such that the clamping element 115 can engage with the trigger element 125 when the release position of the clamping arm 113 is reached. Pivoting of the clamping arm 113 from the clamping position into the open position is effected by this sliding movement V of the clamping element 115.
The clamping element 115 has a sliding surface, which is designed in the form of a ramp, along which the actuating element 129 can be guided. The sliding surface is formed on the end wall of the clamping element 115 in the embodiment shown here. The sliding surface extends from the end wall in the direction of the actuating element 129. The sliding surface is arranged obliquely by being designed as a bevel, so that it extends at an angle of between 130 ° and 160 ° relative to the end wall of the clamping element 115.
The actuating element 129 also has a bevel which is designed to correspond to the inclination of the running surface. The inclined surface of the actuating element 129 is supported in a planar manner on a sliding surface, so that when the actuating element 129 is actuated in the actuating direction B, the inclined surface can slide down along the sliding surface in order to move the clamping element 115.
The actuating element 129 is arranged adjacent to the holding arm 112 of the clamping spring 111. The actuating element 129 is therefore arranged behind the clamping spring 111. The clamping spring 111 is arranged between the section 114 of the current bar 110 and the actuating element 129.
