Description

Conductor connecting clamp with operating element with driving element

Technical Field

The utility model relates to a conductor connecting clamp.

Background

Conductor connecting clips are known from the prior art, by means of which electrical conductors can be reversibly electrically connected to electrical contacts.

For example, DE 102017106720 a1 describes a conductor terminal clamp having a housing with a conductor receiving space which is accessible through a conductor insertion opening for receiving an electrical conductor. A current bar is disposed in the conductor receiving cavity for contacting a conductor introduced into the conductor receiving cavity through the conductor introduction opening. Furthermore, a clamping spring with a spring clamping arm is arranged in the housing, wherein the clamping spring can be actuated between a release state and a clamping state. In the released state, the electrical conductor can be introduced into and/or withdrawn from the conductor receiving space, and in the clamped state, the spring clamping arm exerts a force in the direction of the current bar on the conductor introduced into the conductor receiving space. Finally, the conductor connecting clamp according to DE 102017106720 a1 also comprises an actuating element which can be moved between a clamping position and a release position. The actuating element is operatively connected to the clamping spring in such a way that, when the actuating element is transferred from its clamping position into its release position, the spring clamping arm is acted upon by the actuating element and the clamping spring is transferred from its clamping state into its release state. The conductor terminal described in DE 102017106720 a1 therefore ensures that the inserted electrical conductor is clamped or released in that the actuating element can be moved along an actuating direction, which is parallel to the conductor insertion direction of the electrical conductor into the conductor receiving space.

A similar conductor terminal is also known from DE 102007050683 a1, in which the conductor insertion direction is substantially perpendicular to the actuating direction.

In general, in conductor connecting clamps, the problem arises that the electrical conductor is "misplugged" during the introduction of the electrical conductor into the conductor receiving chamber. Such a "conductor misplug" is to be understood to mean that the electrical conductor, which is to be guided in the direction of the conductor insertion direction in the direction of the current bar, is laterally removed from the specified conductor insertion direction during insertion and is laterally led out of the conductor receiving space. As a result, the electrical conductor does not occupy its intended position in the conductor receiving space. This is problematic in particular in conductor connecting clamps having a housing with open side walls. The risk of conductor misinsertions has a negative effect on the operational safety of the conductor terminal clamp, since reliable contact between the electrical conductor and the current bar cannot be continuously ensured.

In the case of the conductor connecting clip according to the embodiment shown in DE 102007050683 a1, the problem of conductor misplugging is less. Thus, when the electrical conductor is pushed into the conductor receiving space, the spring clamping arm of the clamping spring is initially pressed downward by the pushed-in conductor. The downward movement of the actuating element in the actuating direction is coupled to this closing movement of the spring-clamping arm. By means of this downward movement of the actuating element, the side walls of the actuating element permanently prevent a lateral displacement of the electrical conductor or an exit of the conductor from the conductor receiving space.

However, according to DE 102007050683 a1, the coupling of the closing of the clamping spring to the downward movement of the actuating element is effected in a complicated manner. In this case, additional guide slots are provided on the actuating element or the actuating plunger, into which guide slots guide sections provided specifically on the clamping spring must be hooked. This complex embodiment is accompanied by an increase in production costs, since both the actuating element and the clamping spring must be equipped with special, mutually adapted geometries for engaging the guide section in the guide slot. In addition, installation is complicated by the process of hooking the guide section into the guide slot.

SUMMERY OF THE UTILITY MODEL

It is therefore an object of the present invention to provide a conductor connecting clamp which ensures increased operational reliability and at the same time constitutes a favorable system both in terms of production costs and in terms of installation effort. In particular, it is desirable to avoid the risk of conductor misplugging.

This purpose is realized through the conductor connecting clamp according to the utility model discloses a. Advantageous embodiments of the conductor terminal clamp are described in the description.

More precisely, the object of the invention is achieved by a conductor connecting clamp, comprising a housing having a conductor receiving chamber for receiving an electrical conductor, which is accessible through a conductor introduction opening, wherein the electrical conductor can be introduced into the conductor receiving chamber in a conductor insertion direction. Furthermore, the conductor connection clamp comprises a current bar arranged in the conductor receiving chamber for contacting a conductor introduced into the conductor receiving chamber through the conductor introduction opening. The conductor connecting clamp further comprises a clamping spring arranged in the housing and having a spring clamping arm, wherein the clamping spring can be actuated between a release state and a clamping state, wherein at least in the release state an electrical conductor can be introduced into and/or pulled out of the conductor receiving space, and wherein in the clamping state the spring clamping arm exerts a force on the conductor introduced into the conductor receiving space in the direction of the current bar. The conductor connecting clamp further comprises an actuating element which can be displaced along an actuating direction between a clamping position and a release position, wherein the actuating element is operatively connected to the clamping spring such that, when the actuating element is transferred from its clamping position into its release position, the spring clamping arm is acted upon by the actuating element and the clamping spring is transferred from its clamping state into its release state. Finally, the conductor connecting clip according to the invention is characterized in that the actuating element has at least one first side at its end viewed in the actuating direction and at least one first driver element on the first side. The first side section extends laterally past the spring clamping arm, as viewed in the actuating direction, to below the bottom side of the spring clamping arm. Furthermore, the first driver element projects from the inner side of the first side facing the spring clamping arm in the direction of the spring clamping arm and engages the spring clamping arm from behind at least in the clamping position of the actuating element.

A system that is reliable in operation and is at the same time advantageous can be realized by means of the conductor connecting clamp according to the invention. The closing movement of the clamping spring, i.e. the displacement of the clamping spring from its clamping position into its release position, is no longer coupled to the movement of the actuating element only in such a way that a displacement of the actuating element in the direction of the actuating direction brings about a closing of the clamping spring or of the spring clamping arm. In addition, the coupling of the movement of the clamping spring and the actuating element is also carried out in such a way that the closing of the spring clamping arm or the clamping spring also causes the actuating element to be pulled downward in the actuating direction. This is achieved in that the spring-clamping arm carries the actuating element via a first driver element of the actuating element and pulls it down. The driving force of the spring clamping arm to the first driving element is generated in the direction of the actuating direction and therefore the actuating element is also displaced in the actuating direction.

In this way, even if the clamping spring is in its clamped state and the actuating element is in its clamped position, by introducing an electrical conductor into the conductor connecting clamp, it is possible to bring about a movement of the clamping spring not only in the direction of its release state, but also of the actuating element in the direction of its release position. The displacement of the actuating element in the direction of the actuating direction can even be carried out to such an extent that the actuating element is completely displaced into its release position by the entrainment by the first entrainment element, and thus also the clamping spring is completely displaced into its release state.

The first side of the actuating element and, if necessary, at least one side wall of the actuating element thus permanently form a lateral flank of the conductor receiving space of the housing, also for housings of conductor connecting clamps with open side walls. In this way, conductor misinsertions are avoided, since the conductor introduced into the conductor receiving space cannot be laterally removed from the conductor receiving space and therefore cannot be misinserted. This is avoided by blocking this outlet of the electrical conductor by the side wings, i.e. by the side portions or side walls of the operating element. Thus, a conductor misinsertion is no longer prevented when the conductor is introduced only if the actuating element has been moved into the release position, but is now also prevented when the conductor is introduced if the actuating element is still in its clamping position. Since, when the conductor is introduced into the conductor receiving space, the actuating element, which is still in the clamped position, is also pushed by its driver element in the direction of the actuating direction, the lateral wings of the actuating element thereby close the lateral outlet from the conductor receiving space. This achieves a reliable conductor connecting clamp, in which a conductor is reliably prevented from being inserted by mistake.

This also does not require a complicated structural solution as in the prior art. No guide slot is provided on the actuating element and therefore no complicated suspension of the spring clamping arm into the guide slot is required. Furthermore, no special design of the clamping spring with respect to the geometry of the spring clamping arm is required. For example, lateral projections are not required on the spring clamping arms, but rather, conventional, geometrically simple clamping springs can be used in the conductor connecting clamp according to the invention. This results in an advantageous conductor connecting clip which can be produced in a simple manner and which can also be assembled in a simple manner.

The side or the inner side of the side can thus be embodied without interruption, i.e. no complicated gap sections are required to suspend the spring-clamping arm, for example, in order to couple the movement of the spring-clamping arm to the movement of the actuating element.

The underside of the spring clamping arm refers to the side of the spring clamping arm facing away from the main body part of the actuating element. In other words, the bottom side of the spring clamping arm is the side of the spring clamping arm which, viewed in the actuating direction, faces away from the actuating element or is further away from the actuating element.

Furthermore, the described clamping of the actuating element by the first driver element from behind can also be achieved at least in the clamping position of the actuating element at a position after the actuating element has been displaced in the actuating direction, for example even in the release position of the actuating element.

The first side preferably extends along or parallel to the actuating direction towards the inner side of the spring clamping arm. The first driver element extends from this inner side of the first side in the direction of the spring clamping arm, preferably stands vertically on the inner side of the first side.

The side or the inner side of the side can at the same time also assume a lateral guiding function for the actuating element. In particular in conductor connecting clamps with open side walls of the housing, there is therefore a risk of the actuating element tilting out or sliding out laterally from the conductor receiving space. In the case of a conductor connecting clip according to the invention, this can be avoided in that, when the actuating element is moved laterally, the inner side of the side section passing the spring clamping arm is struck by the side face against the side face of the spring clamping arm and thus prevents this lateral movement.

The actuation or actuation process of the actuating element is understood to mean a process of moving the actuating element from its clamping position into its release position. During the actuation, the clamping spring is moved from its clamping state into its release state by closing the spring clamping arm or the clamping spring and releasing the electrical conductor which may have been clamped beforehand.

The steering element may also be referred to as a steering Pusher or Pusher. The actuating element can preferably have an actuating section (or also referred to as a use section) and a pushing section (or also referred to as a pusher section). The pressing section of the actuating element is preferably always in contact with the spring clamping arm of the clamping spring.

Preferably, the actuating element is arranged such that pressing the actuating element in the direction of the actuating direction, i.e. applying a force to the actuating element in the form of an actuating force in the direction of the actuating direction, causes the actuating element to be displaced in the direction of the clamping spring. This results in the closing of the spring clamping arm or the clamping spring, which is thereby transferred from its clamped state into its released state. In this case, the bending joint of the clamping spring is preferably deformed by a transition from its clamping state to its release state in such a way that the contact arm of the clamping spring and the spring clamping arm enclose a smaller angle with one another in their release state than in the clamping state of the clamping spring. The clamping spring therefore preferably has, on the one hand, a spring clamping arm, which is the movable arm of the clamping spring, and an additional fixed, immovable abutment arm, as well as a bending joint, which interconnects the spring clamping arm and the abutment arm and about which the spring clamping arm rotates when the clamping spring is opened or closed.

The steering direction (or also referred to as the pusher direction) may preferably be substantially perpendicular to the conductor insertion direction.

The housing is preferably formed of an electrically insulating material. The housing may also be referred to as an insulating material housing.

The electrical conductor can be inserted or pushed into the conductor receiving chamber through the conductor insertion opening in the conductor insertion direction. In this case, the electrical conductor can be inserted or pushed into the conductor receiving space in a simple manner, in particular when the clamping spring is in the released state and, for example, the actuating element is in the released position. That is, there is no resistance against the introduction of the electrical conductor in the conductor insertion direction due to the spring clamping arms which open the clamping spring. Furthermore, the electrical conductor can also be introduced when the clamping spring is in the clamped state and, for example, the actuating element is in the clamped position. However, when the conductor is pushed in, the resistance of the open spring clamping arms of the clamping spring against the displacement of the electrical conductor in the conductor insertion direction into the conductor receiving space must be overcome. This requires a greater force to be expended in pushing in the electrical conductor than when the clamping spring is biased to the released state.

The current bar has an electrically conductive region at least in the contact region. Preferably, the current bar is formed from an electrically conductive material, such as a metal. Furthermore, the current bar is electrically/galvanically connected to further electrical contact means, for example an electrical contact pin and/or an electrical contact socket.

According to an advantageous embodiment, the actuating element has a second side on its end viewed in the actuating direction on the side disposed opposite the first side, and a second driver element on the second side. The second side section extends laterally past the spring clamping arm, as viewed in the actuating direction, to below the bottom side of the spring clamping arm. Furthermore, the second catch projects from the second side in the direction of the spring clamping arm toward the inner side of the spring clamping arm and engages the spring clamping arm from behind. This results in a more reliable conductor connecting clamp, since the driving of the actuating element is no longer effected only by the first driving element when the spring clamping arm is closed, but is additionally supported by the second driving element. The inner side of the second side facing the spring clamping arm can preferably extend along or parallel to the actuating direction. The second driver element preferably extends from this inner side of the second side part perpendicularly upright on the inner side of the second side part in the direction of the spring clamping arm. The features described above with respect to the first side and the first driver element can also be applied to the second side or the second driver element.

According to a further advantageous embodiment of the conductor connecting clamp, the first driving element, preferably additionally the second driving element, can also engage the spring clamping arm from behind when the actuating element is in a position between the clamping position and the release position. In this case, the one or more driver elements can also engage the spring clamping arm from behind when the actuating element is in the release position. As an alternative, however, the actuating element can also be displaced in its release position in the actuating direction by such a distance that the one or more driver elements no longer engage the spring clamping arm from behind in the release position. In other words, the actuating element is displaced in the actuating direction by a displacement into its release state to such an extent that the first or possibly the second driver element no longer engages the spring clamping arm from behind.

According to a further advantageous embodiment of the conductor connecting clip, the first driving element, preferably additionally the second driving element, slides along the underside of the spring clamping arm when the clamping spring is transferred from its clamping state into its release state. This sliding movement along the underside ensures that the first or second driver element is permanently in contact with the underside of the spring clamping arm. This provides a more reliable conductor connecting clamp, since regardless of the initial position of the clamping spring, the driving of the actuating element by the first or second driving element is ensured by the permanent contact between the underside of the spring clamping arm and the driving element when the spring clamping arm is closed.

According to an advantageous embodiment, the actuating element can have at least one first actuating arm, wherein the first side extends in the actuating direction next to the first actuating arm.

Further preferably, the actuating element can also have a second actuating arm, wherein a free space is provided between the first actuating arm and the second actuating arm. Preferably, the second side section extends in the actuating direction next to the second actuating arm.

The electrical conductor introduced into the conductor receiving space can be arranged in the free space between the two actuating arms. A particularly compact embodiment of the conductor connecting clamp is thereby achieved.

The actuating arm preferably extends parallel to the actuating direction or along the actuating direction. The first or second actuating arm can be a pushing section (also referred to as a pusher section) of the actuating element and is therefore responsible for actuating the clamping spring, i.e. the closing spring clamping arm.

Detailed Description

In the following description, the same reference numerals denote the same members or the same features, so that the description about one member with reference to one drawing is also applicable to other drawings and repetitive description is avoided. Furthermore, each feature described in connection with one embodiment can also be applied to other embodiments separately.

Fig. 1 shows a conductor connecting clip 1 according to the invention. The conductor connecting clamp 1 has a housing 10 which is made of an electrically insulating material or at least has an electrically insulating material. The housing 10 has a conductor insertion opening 11, via which a conductor receiving chamber 12 of the housing 10 is accessible. The electrical conductor L can be introduced into the conductor receiving chamber 12 through the conductor introduction opening 11 by introducing or pushing the electrical conductor L into the conductor receiving chamber 12 along the conductor insertion direction R.

Furthermore, the conductor terminal clamp 1 has a current bar 20 arranged in the conductor receiving space 12, which current bar 20 is designed to contact an electrical conductor L introduced into the conductor receiving space 12 through the conductor inlet opening 11. The current bar 20 is made of an electrically conductive material, for example of steel plate. Furthermore, the current bar 20 is electrically connected to further electrical contacting means, for example electrical contact pins and/or electrical contact sockets, wherein the further electrical contacting means are not shown in the figures.

Furthermore, a clamping spring 30 is arranged in the housing 10, which clamping spring has an abutment arm 31 and a spring clamping arm 32, wherein the abutment arm 31 and the spring clamping arm 32 are connected by a bending joint 33. The clamping spring 30 may be placed in different states by changing the position of the movable spring clamping arm 32. Thus, the clamping spring 30 may be placed in the clamped state shown in fig. 2A and 2C or the released state shown in fig. 1 and 2B.

In other words, the clamping spring 30 can be manipulated between its clamped state and its released state. The actuation process therefore describes the process of how the clamping spring 30 enters its released state (fig. 1, 2B) from its clamped state (fig. 2A, 2C, 3A, 3B).

The transition of the clamping spring 30 from its clamping state to its release state is effected by actuation of the actuating element 40, for example manually or by means of a tool. At this time, the actuating element 40 is displaced in the actuating direction B, i.e. the actuating element 40 is pressed downward. In this case, the actuating element is moved from the clamping position shown in fig. 2A or 2C or 3A or 3B into the release position shown in fig. 1 or 2B. During this transition from its clamping position to its release position, the actuating element 40 presses against the spring clamping arm 32 of the clamping spring and thus closes the clamping spring 30, thereby bringing the clamping spring 30 from its clamped state into its release state. In this case, the spring clamping arm 32 encloses a greater angle with the abutment arm 31 in the clamped state than in the released state. In other words, the actuating element 40 applies an actuating force to the spring clamping arm 32 of the clamping spring 30 during the actuating process and thus closes the clamping spring 30.

The movement of the clamping spring 30, in particular the spring clamping arm 32, is thus coupled to the movement of the actuating element 40. The coupling is designed such that pressing the actuating element 40 in the actuating direction B also causes a displacement or rotation of the spring clamping arm 32 in the actuating direction B, i.e. a closing of the clamping spring 30.

As can also be seen from fig. 1, the actuating element 40 has a first side 41. The first side 41 is arranged at an end of the actuating element 40, viewed in the actuating direction B. The first side 41 forms a lateral flank for the conductor receiving space 12. Therefore, the first side portion 41 also assumes a guiding function for the electrical conductor L. By preventing the electrical conductor to be introduced into the conductor receiving space 12 from being able to leave the conductor receiving space 12 laterally during the introduction, a so-called conductor misplugging is avoided, since the first lateral portion 41 blocks this separation. This is particularly advantageous in the case of a conductor connecting clip 1 comprising a housing 10 with open side walls.

Furthermore, the first side 41 also assumes a further lateral guiding function, to be precise with respect to the actuating element 40 itself. The first side 41 therefore extends laterally, as viewed in the actuating direction B, past the spring clamping arm 32 as far as below the bottom side 34 of the spring clamping arm 32 (see fig. 2A, 2B and 2C). It is thereby avoided that the actuating element 40 can be deflected laterally from the first side 41 in the direction of the spring clamping arm 32, for example during actuation, i.e. when pushed in the direction of the actuating direction B. This is because such a lateral movement of the actuating element 40 is prevented by the impact on the spring clamping arm 32. The first side 41 is embodied uninterrupted, that is to say without a gap section or the like.

The actuating element 40 can be fixed or secured not only in its clamping position but also in its release position. Thus, no force or actuation of the actuating element 40 in the direction of the actuating direction B is required to be applied continuously in order to hold the actuating element 40 in its release position, for example.

The aforementioned coupling of the movements of the actuating element 40 and the spring-clamping arm 32 is such that a movement of the actuating element 40 in the actuating direction B causes the closing of the spring-clamping arm 32. In addition, the movements of the spring clamping arm 32 and the actuating element 40 are also coupled in such a way that a downward deflection of the spring clamping arm 32 in the actuating direction B also leads to a displacement of the actuating element 40 in the actuating direction B. This is particularly advantageous if the electrical conductor L is to be inserted into the conductor receiving space 12 without the clamping spring 30 having to be moved into its release position (fig. 2B) or the actuating element 40 having to be moved into its release position (fig. 2B). Thus, the electrical conductor L can also be introduced via the conductor introduction opening 11 of the conductor connection clamp 1, while the clamping spring 30 is still in the clamped state and the operating element 40 is still in its clamped position, i.e. in the state as shown in fig. 2A. The introduction of the electrical conductor L then causes an impact on the spring clamping arm 32, which is then deflected about the bending joint 33 in the actuating direction B. This downward deflection of the spring-clamping arm 32 then likewise causes a coupled movement of the actuating element 40 downward in the actuating direction B.

The coupling of the movements is illustrated by means of the diagrams in fig. 3A and 3B. Thus, by the spring clamping arm 32 exerting a force on the first driving element 45 in the actuating direction B and thus moving the first driving element 45 and thus ultimately the entire actuating element 40 downward, the actuating element 40 is displaced from the clamping position shown in fig. 3A downward in the actuating direction B into the position shown in fig. 3B.

For this purpose, a first driving element 45 is arranged on the first side 41. In particular, the first driver element 45 projects from an inner side 47 of the first side 41 facing the spring clamping arm 32 in the direction of the spring clamping arm 32 and engages the spring clamping arm 32 from behind. At least in the clamping position of the actuating element 40 shown in fig. 3A, the spring clamping arm 32 is engaged from behind by the first driver element 45 from below.

Furthermore, as shown in fig. 3B, the first driver element 45 can also engage the spring clamping arm 32 from behind in a position between the clamping position and the release position of the actuating element 40. In the release position, the actuating element 40 can optionally be translated downward in the actuating direction 40 to such an extent that the first driver element 45 no longer engages the spring clamping arm 32 from behind in the release position.

The projection of the first driver element 45 from the inner side 47 of the first side 41 can be better seen in the exemplary embodiment of the actuating element 40 shown in fig. 4A. The first driver element 45 is here substantially perpendicular to the inner side 47 of the first side 41.

An inner side 47 of the first side 41 facing the spring clamping arm 32 extends along or parallel to the actuating direction B.

Furthermore, the actuating element 40 may also have a second side 42 at its end viewed in the actuating direction B on the side arranged opposite the first side 41, as can be seen from the further exemplary embodiment shown in fig. 4B. The second side 42 extends, as viewed in the actuating direction B, laterally of the spring clamping arm 32 as far as below the bottom side 34 of the spring clamping arm 32. In this case, a second driver element 46 can also be provided on the second side 42, wherein the second driver element 46 projects from the inner side of the second side 42 facing the spring clamping arm 32 in the direction of the spring clamping arm 32 and engages the spring clamping arm 32 from behind.

The first driver element 45, preferably additionally the second driver element 46, slides along the underside 34 of the spring clamping arm 32 when the clamping spring 30 is transferred from its clamped state into its released state, as is shown with the aid of the two illustrations in fig. 3A and 3B, wherein the clamping spring 30 is in different positions and the contact point between the clamping spring 30 and the first driver element 45 is different. This sliding along the bottom side 34 ensures that the first or second driver element 45, 46 is permanently in contact with the bottom side 34 of the spring clamping arm 32.

Furthermore, as can be seen from fig. 4A and 4B, the actuating element 40 can have a first actuating arm 43 and a second actuating arm 44. A vacant space 48 is further formed between the first and second manipulating arms 43 and 44. The free space 48 prevents the electrical conductor L to be introduced into the conductor receiving space 12 and the actuating element 40 from jamming against one another. A sufficient accommodation space for the electrical conductor L to be introduced is provided and at the same time a compact conductor connection clamp 1, in particular a compact operating element 40, is provided. The first side 41 extends in the actuating direction B in connection with a first actuating arm 43. If a second side 42 is provided, as provided in the exemplary embodiment according to fig. 4B, this second side 42 extends in the actuating direction B in connection with a second actuating arm 44.
