Description

Connecting terminal
Technical Field
The invention relates to a connection terminal having at least one spring-force clamping connection for connecting an electrical line, wherein the spring-force clamping connection has at least one clamping spring, wherein the connection terminal has: a housing having an operating channel formed therein; and a button element arranged in the operating channel in a longitudinally displaceable manner, said button element being designed for operating the clamping spring, wherein the button element has at least one first and one second button part, wherein the first and the second button part are designed as two separate components, and the first button part is mounted in a manner such that it can be rotated relative to the second button part about a longitudinal axis.
Background
Terminals with a push-button operation are known, for example, from DE 29920231U 1.
Disclosure of Invention
The invention is based on the object of proposing a connecting terminal with further improvement of the push-button operation.
This object is achieved in a terminal of the type mentioned at the outset in that the second push button part is guided in the actuating channel in a form-fitting manner and in a manner that it cannot be rotated about the longitudinal axis, wherein the first push button part is rotatable relative to the second push button part only in the deflected state of the push button element, and is otherwise guided in the actuating channel in a form-fitting manner and in a manner that it cannot be rotated about the longitudinal axis. This can be achieved, for example, in that during the movement of the push button element from the undeflected position (initial position) into the deflected state, the first push button part is guided in the operating channel in a rotationally fixed manner and is then only rotatable relative to the second push button part when the deflected state is reached, in which the clamping spring is deflected. In this deflected state, the form-fitting element of the first push button part, which will be explained further below, and at the operating channel can reach the overlapping position. For example, the second push-button part can always be guided in a rotationally fixed manner, and only the first push-button part can have a rotational possibility, also in a deflected state.
In this way, the button element as a whole can be guided in the operating channel without friction and without play, wherein the additional functions mentioned can be realized by the first button part due to the rotatability.
This allows a length-variable pushbutton element to be realized with little effort and simple constructional measures. The first button portion may be, for example, a portion to be manually operated, which is operated by a user directly by hand or by means of a tool. The second push-button part has a loading region, by means of which the second push-button part loads the clamping spring when the push-button element is actuated and the clamping point of the spring-force clamping connection is to be opened.
In this way, a two-part rotary push button for the connection terminal can be realized. This allows for the integration of additional functions into the button element and terminal assembly. For example, a locking of the button element in the operating position can be achieved in the manner described.
The first button part and the second button part can be mounted so as to be rotatable about an axis which is basically arbitrary here. Advantageously, the first and second push button portions are rotatably supported relative to each other about a longitudinal axis of the push button element. In an advantageous embodiment of the invention, the rotatability of the first button portion relative to the second button portion can be limited to a maximum angle, for example a maximum angle of 45 degrees. The angular limitation of the rotatability can be achieved, for example, by a mechanical stop in the region of the coupling between the first and second push-button parts and/or a mechanical stop between at least one of the two push-button parts and a part of the housing of the connection terminal, for example in the region of the operating channel.
According to an advantageous embodiment of the invention, it is provided that the button element is designed to be variable in length. In this case, the button element can be designed in particular to be variable in its length in the operating direction, in which it is longitudinally movable in the operating channel. By virtue of the length variability, the button element can be improved by means of additional functions, such as, for example, a hinged connection between the individual button parts. In particular, the button element can be designed with a flexibility or elasticity that is increased over a certain length due to the length variability, so that during operation, it also follows an operating channel that is designed to be curved or bent in the operating direction. This is advantageous in case the change in length of the button element is caused by a rotation of the first button portion relative to the second button portion.
According to an advantageous embodiment of the invention, it is provided that the terminal, in particular the housing thereof, has a first positive-locking element in the region of the operating channel and the first pushbutton portion has a second positive-locking element on the outer circumference, the first positive-locking element being associated with the second positive-locking element as a counterpart, so that a positive-locking coupling between the first pushbutton portion and the operating channel can be established by the connection of the first positive-locking element with the second positive-locking element. Accordingly, the button element can be locked at least in a specific state, for example in a deflected state in which the clamping point of the terminal is open. In this way, the push button element is also not moved back into the initial position again by the restoring force of the clamping spring, but rather remains in the occupied position due to the positive coupling between the first push button part and the second push button part. The button element is then locked in the longitudinal direction. The locking can easily be removed again by a corresponding further rotation or swiveling back of the first button part by the user, for example when the clamping site should be closed.
According to an advantageous embodiment of the invention, it is provided that the positive fit between the first positive-fit element and the second positive-fit element can be established by a rotational movement of the first push button part relative to the second push button part. This allows simple operation of the button element by the user. The button element can be operated as any conventional button of a connecting terminal, wherein the locking of the button element can be carried out by a simple rotational movement in a state in which a form-fitting correspondence can be established. The rotational movement of the first push button portion relative to the second push button portion is preferably carried out at an angle of 45 °, wherein the angular deviation is preferably up to 10 ° (i.e. in the range of 35 ° to 55 °). This allows simple operation, since the rotational movement is only carried out over a relatively small angular range of significantly less than 90 °. Here, the form fit between the first and second form-fitting elements can only be established in the deflected state of the button element, that is to say when the first and second form-fitting elements have a respective overlapping position.
According to an advantageous embodiment of the invention, it is provided that the first and second push button parts are connected to each other via a hinge. This allows a mechanically simple coupling between the first and second button portions, which selectively allows the mentioned rotatability and/or additional degrees of freedom of movement between the first and second button portions, such as for example the pivotability of the first button portion with respect to the second button portion. The first button portion may be pivotable relative to the second button portion, for example in the direction of the longitudinal axis of the button element or in the operating direction.
According to an advantageous embodiment of the invention, it is provided that the first pushbutton part is connected to the second pushbutton part via a form-fitting coupling. In this way, the first and second button portions can be permanently connected to one another such that they cannot be unintentionally released from one another. This can also be designed releasably, depending on the type of positive-locking coupling.
According to an advantageous embodiment of the invention, the positive-locking coupling has a pin/pin receptacle connection or a ball/socket connection. This allows for multiple degrees of freedom of movement between the first and second button portions. The pin of the pin/pin receptacle connection can have, for example, a cross-sectional enlargement toward the free end, so that it is designed mushroom-head-like. The pin receptacle can be formed as a counterpart to this embodiment of the pin, wherein the pin receptacle can have an excess dimension in relation to the pin in the operating direction of the pushbutton element in order to achieve a length variability of the pushbutton element.
According to an advantageous embodiment of the invention, it is provided that the first button part and the second button part have respective end faces facing each other, via which end faces an operating force can be transmitted from the first button part to the second button part when the button element is operated. In this way, the operating force can be transmitted over a relatively large area, so that a small pressure per unit area can be achieved. This has the advantage that the first and second push button parts can also be constructed, for example, as plastic components.
According to an advantageous embodiment of the invention, it is provided that the operating channel is formed in a bent and/or curved manner in the operating direction of the pushbutton element. This allows a space-optimized configuration of the connection terminal. The construction of the terminal is not limited to the fact that the operating channel must extend in a straight line as a whole. By providing at least one bend or bend of the operating channel, the operating channel can be arranged, for example, in a particularly space-saving manner next to the conductor insertion channel of the connecting terminal. By means of an advantageous configuration of the button element according to the invention, the button element can follow such a bent or curved operating channel during operation.
According to an advantageous embodiment of the invention, it is provided that the operating channel has at least one first section and a second section arranged behind the first section in the operating direction of the push button element, wherein an angle is formed between the center axis of the first section and the center axis of the second section. Here, for example, the first button portion can be associated with a first section of the operating channel and the second button portion with a second section. When the button element is actuated, the first button part is at least largely displaced in the first section and the second button part is at least largely displaced in the second section.
According to an advantageous embodiment of the invention, it is provided that the button element has a flexibility in at least one region in which the button element can be deformed during a longitudinal movement in which the button element passes through a bent and/or curved portion of the operating channel. In this way, the button element can follow a bent or curved operating channel very well. The flexibility here relates to a possible pivoting or tilting movement of the first push button part relative to the second push button part about an axis oriented perpendicular to the operating direction. In this case, the first push-button part and the second push-button part can also be connected to one another in one piece via a film hinge connection, which enables a twisting movement of the push-button parts relative to one another about a longitudinal axis and a tilting movement about a tilting axis oriented perpendicular to the longitudinal direction.
It is also conceivable that the first button part and the second button part are first produced in one piece, for example as an injection-molded part, and that there are theoretical breaking points in the connecting region between the first button part and the second button part. In a first rotational movement of the first push button part relative to the second push button part, the breaking of the theoretical breaking point then occurs, so that, in the further use, the first push button part and the second push button part are present as separate components and can have the configuration according to the invention.
According to an advantageous embodiment of the invention, the first push button portion is shorter in the longitudinal direction or operating direction than the second push button portion. Thus, the first button portion may be, for example, the highest half of the length of the second button portion in the longitudinal direction or in the operating direction. This makes it possible to achieve a particularly space-saving arrangement of the entire pushbutton element in the terminal.
According to an advantageous embodiment of the invention, the first button part has a slit or groove on the side pointing forward from the second button part. This has the advantage that the button element can be operated in a simple and reliable manner on the first button portion by means of a tool, for example a screwdriver.
The object mentioned at the outset is achieved according to a further independent aspect of the invention by a terminal having at least one spring-force clamping connection for connecting an electrical conductor, wherein the spring-force clamping connection has at least one clamping spring, wherein the terminal has: a housing having an operating channel formed therein; and a button element arranged longitudinally movably in the operating channel, which button element is set up for operating the clamping spring, wherein the button element has a first button portion and a second button portion, which second button portion is pivotable relative to the first button portion about a rotational axis, characterized in that,
the button element is arranged movably in the operating channel along the operating direction, and
the operating direction and the axis of rotation are oriented largely parallel to one another.
Thereby, the advantages mentioned above are also achieved. The connecting terminal can be designed in particular as a connecting terminal according to at least one of the embodiments described above. The feature that the operating direction and the axis of rotation are oriented largely parallel to one another is to be understood as follows, the operating direction and the axis of rotation not necessarily having to be exactly parallel or coincident, but rather may have at least a small angular deviation from one another, for example an angular deviation of up to 10 degrees or an angular deviation of up to 5 degrees.
The indefinite article "a" or "an" is not to be construed as a word or phrase in the scope of the present invention. Thus, if for example a component is mentioned, this is to be interpreted in the sense of "at least one component", as long as the angular description is made in degrees, which relates to a circumference of 360 degrees (360 °).

Detailed Description
Fig. 1 shows a partial connection terminal 1. The terminal 1 has a housing 2, for example an insulating material housing. An operating channel 20 is formed in the housing 2, in which operating channel the button element 5 is arranged so as to be longitudinally displaceable in the operating direction B. Adjacent to the actuating channel 20, the housing 2 has a conductor insertion channel 23, in which conductor insertion channel 23 an electrical conductor can be guided to a clamping point of the connection terminal 1. In the housing 2, a bus bar 3 and a clamping spring 4 are present as components of a spring-force clamping connection. The clamping spring 4 has an abutment leg 41, a spring bow 42 and a clamping leg 43. In this case, a clamping point is formed between the clamping leg 43 and a part of the busbar 3. The clamping spring is supported via the abutment leg 41 with respect to the clamping force applied to the electrical conductor at the clamping point. The abutment leg 41 can be fixed to the busbar 3 or can abut against it, for example.
The operating channel 20 has a first section 21 and a second section 22 arranged behind the first section 21 in the operating direction B of the button element 5. It can be seen that the working channel 20 does not run straight here, but is bent at the transition from the first section 21 to the second section 22.
The button element 5 serves to actuate the clamping spring 4, if the button element 5 is manually loaded with an actuating force from the outside of the connecting terminal 1, said actuating force being transmitted via a loading region 62 at the button element 5 to the clamping leg 43 of the clamping spring 4. The clamping legs 43 are deflected in the manner described, so that the clamping point is opened. Fig. 1 shows the state of the button element 5 not being operated. Fig. 2 shows the state of the button element 5 being operated, wherein the clamping leg 43 is deflected downward.
The button element 5 is formed at least in two parts, namely with a first button part 51 and a second button part 52. The first button portion 51 and the second button portion 52 are hingedly connected to each other via a hinge 53. The hinged connection between the first button portion 51 and the second button portion 52 furthermore constitutes a certain play in the operating direction B, so that the button element 5 is variable in length in said direction. It can be seen that in the inoperative state of fig. 1, the button element is slightly longer than in the operative state of fig. 2.
The button element 15 has, for example, on the first button part 51 on the side pointing outwards, a slit 54 or a groove for operating the button element 5 by means of a tool.
Fig. 3 to 5 show the button element 5 in different respective operating states. In fig. 3, the first button portion 51 is not yet connected to the second button portion 52. It can be seen that the first button portion 51 has a protruding peg 55. The peg 55 is associated with a peg receptacle 56 in the second button portion 52. If the first button part 51 is connected to the second button part 52, as shown in fig. 4, the peg 55 is sunk into the peg receiver 56 and a form-fitting coupling is formed between the first and second button parts 51, 52. The peg 55 may have a mushroom-head-like shape, by means of which it can snap into the peg receptacle 56 due to a certain oversize. The first button portion 51 is connected with the second button portion 52 in such a way that it cannot be undesirably released from the second button portion. The first button part 51 can also be separated again from the second button part 52 with increased effort. The form-fitting coupling between the first button portion 51 and the second button portion 52 not only allows a certain lateral pivoting of the first button portion 51 relative to the second portion 52, but also a rotational movement of the first button portion 51 relative to the second button portion 52 about the rotational axis a. Fig. 5 shows the push button portion 5 with the first rotational part 51 slightly rotated about the rotational axis a with respect to fig. 4.
Fig. 4 and 5 each depict a sectional plane S. Fig. 6 and 7 each show the button element in a sectional view in a sectional plane S.
Further aspects of the displaceability of the first push button portion 51 with respect to the second push button portion 52 can be explained by means of the side sectional views of the push button element 5 in fig. 6 and 7. It can be seen that the first button portion 51 has a shoulder 58 on the side facing the second button portion 52. The second push-button part 52 has a recess 59 at the upper end of the bolt receptacle 56, which is designed in terms of size and shape for receiving the shoulder 58. In the first rotational position of the first push button part 51 relative to the second push button part 52 shown in fig. 4 and 7, the shoulder 58 does not sink into the recess 59, since this is prevented by the shape of the shoulder 58 and the recess 59 in the first rotational position. The shoulder 58 of the first push button portion 51 lies here on the end face 61 of the second push button portion 52 facing the first push button portion. In this state, the button element 5 is longer than in the state shown in fig. 5 and 6. In fig. 5 and 6, the first push button part 1 is rotated slightly about the axis of rotation a, so that the shoulder 58 can be pressed into the recess 59 and sunk therein.
Fig. 8 shows the formation of the shoulder 58 and the pin 55 in an exemplary view of the side of the first push-button part 51 facing the second push-button part 52 which is well visible. As fig. 9 shows, the pin receiver 56 is formed wider in the upper region of the recess 59 and is substantially adapted in terms of shape to the contour of the shoulder 58.
Furthermore, an end face 60 of the first button portion 51 and an end face 61 of the second button portion 52 are visible, which end faces face each other when the first button portion 51 is connected with the second button portion 52.
The manner of action of the push button element 5 when the clamping point is opened and when it is locked on the housing 2 is explained in detail with reference to the views in fig. 10 and 11. Fig. 10 corresponds to the state shown in fig. 1, and fig. 11 corresponds to the state shown in fig. 2. Viewed on the side of the connecting terminal 1 on which the inlet to the operating channel 20 and the inlet to the wire lead-in channel 23 are located, respectively.
Based on the assumption of the inoperative state of the button element 5 shown in fig. 1 and 10, the button element 5 is now loaded with an operating force, which acts on the first button portion 51. As a result, the button element 5 is pressed further into the actuating channel 20 and thereby deflects the clamping leg 43. If a specific operating state is reached, for example a maximum press-in of the button element 5, the first button part 51 is rotated by a certain angle about the axis of rotation a in order to lock the button element 5 substantially in said position. Here, the second formfitting element 57 formed on the first push button part 51 engages into the first formfitting element 24 formed on the housing 2, for example into a lateral recess in the operating channel 20. Thereby, the operating position of the button element 5 is locked. However, if the operating force is removed, the button element 5 remains in the operating position. As a result of the rotation of the first push button portion 51, the shoulder 58 now also sinks into the recess 59, as shown in fig. 6.
If the locked button element 5 is to be released again, the first button portion 51 is simply rotated again in the opposite rotational direction until it at least approximately reaches the position shown in fig. 10. The button element 5 can then be moved back again into the original position as shown in fig. 1 by the restoring force of the clamping leg 43. As can be taken from fig. 10, in a plan view towards the end side 61 of the second push button portion 52, the contour of the first push button portion 51 is arranged within the contour of the second push button portion 52, so that the push button element 5 can move freely in the operating channel 20.
Fig. 12 shows a complete connecting terminal 1, which may have a plurality of such spring-force clamping connections and button elements 5, for example. It is exemplarily shown that the button element 5 visible on the left is operated, whereas the button element 5 shown on the right is not operated.
