Definitions

  • the invention relates to a connection device for connecting an electrical line according to the preamble of claim 1.
  • connection devices of this type it is desirable to enable an electrical line to be connected in a simple manner. It can be advantageous here that the connection device closes automatically when an electrical line is plugged in, i.e. a contacting element is automatically transferred from an open position to a contacting position in order to make secure and reliable contact with the electrical line inserted into the plug-in opening of the housing.
  • a contacting element is automatically transferred from an open position to a contacting position in order to make secure and reliable contact with the electrical line inserted into the plug-in opening of the housing.
  • Such an automatic triggering should not only be possible with a comparatively rigid electrical line, for example with a ferrule or wire arranged on an electrical line, but also with an electrical line that is inserted into the plug-in opening of the housing with a comparatively low insertion force , for example in the form of a stranded conductor.
  • connection device to be delivered in its open position in order to enable an electrical line to be connected directly in the context of intended use.
  • the contact-making element of the connection device should therefore, if possible, not trigger even in the event of shock or vibrations.
  • a spring-loaded terminal which has a flexible retaining spring for locking a clamping spring in an open position, the clamping spring being transferable from the open position into a contacting position and being brought back into the open position by a tool.
  • connection device which has a status indicator which, by the action of an inserted cable, indicates a sufficiently deeply inserted and thus contacted state.
  • the object of the present invention is to provide a further improved connection device for connecting an electrical line.
  • a connection device for connecting an electrical line which comprises a housing, a current conductor and a contacting element.
  • the contacting element can be moved from an open position into a contacting position in order to contact the electrical line (inside the housing) with the current conductor.
  • a display element mounted adjustably to the housing is provided, which is coupled to the contacting element in such a way that the display element can be used to indicate whether the contacting element is in the open position or in the contacting position.
  • connection device which is improved in particular in such a way that a user can always recognize the state of the connection device in a simple manner.
  • the contacting element can be locked in the open position.
  • This not only improves the convenience of operation, it can also be seen at a glance whether the connection device is also in the contacting position when an electrical line is plugged in. Even with a large number of connection devices, for example arranged next to one another, it is thus possible in a particularly rapid manner to check the correct state of all connection devices, this test being particularly less prone to errors by the display device.
  • the current conductor is designed in the form of a current bar.
  • the current bar has, for example, a bar section with which an electrical line is pressed into contact via the contacting element, so that the electrical line makes electrical contact with the bar section.
  • another electrical line or the current bar can be connected to the current bar can have electrical connections, for example, for arranging the connection device on a printed circuit board or for connecting to an associated plug connector.
  • the contacting element (in particular multiple times) can be returned from the contacting position to the open position, in particular by the action of force in one actuation direction.
  • the display element is mounted on the housing in such a way that it can be moved relative thereto in a direction different from the direction of actuation.
  • the display element is mounted on the housing so that it can rotate about an axis of rotation.
  • this enables a space-saving arrangement.
  • it is thus possible to arrange the display element in such a way that it cannot be inadvertently adjusted by external action.
  • the display element is coupled to the contacting element in such a way that it is adjusted relative to the housing both when the contacting element is moved from the open position to the contacting position and when the contacting element is moved from the contacting position to the open position.
  • the contacting element determines the position of the display element in each of its positions. It is thus always clearly recognizable in which position the contacting element is located.
  • the display element is coupled to the contacting element via a coupling element.
  • the coupling element is, for example, articulated to the display element and / or articulated to the contacting element.
  • the coupling element connects the display element with the contacting element.
  • the coupling element is set up, for example, to transmit forces from the contacting element to the display element, in particular in two possible directions, for example a thrust force and a tensile force.
  • the coupling element is an adjusting bracket.
  • the coupling element is eccentric to the axis of rotation of the display element in engagement with the display element.
  • the coupling element engages in the display element.
  • the coupling element is in engagement with a section of the contacting element, for example engages in an opening therein.
  • the display element can have several display areas, in particular several display areas different in shape and / or color (e.g. signal color).
  • the status of the display device can thus be quickly identified. For example, a red display area stands for the contacting position and a green display area stands for the open position.
  • the housing has a viewing area in which a section of the display element is visible. It can be provided that, depending on the position of the contacting element, (only) one of the display areas of the display element is visible in the viewing area.
  • one of the display areas of the display element is larger than another of the display areas. This enables, for example, compensation for electrical lines with different sized cross-sections.
  • a display area assigned to the contacting position is larger than a display area assigned to the open position.
  • the larger display area is, for example, larger in one direction of adjustment of the display element than the smaller display area.
  • the display element is optionally designed in the form of a wheel or a roller.
  • the display element can, in particular in an embodiment in the form of a wheel and / or a roller, be movably, in particular rotatably, mounted in a bearing receptacle of the housing.
  • a rocker element is movably, in particular rotatably, held at at least one bearing point and is designed to hold the contacting element in its open position in a holding position, the rocker element being able to be moved from the holding position into a release position as a result of the action of the electrical line, in particular is pivotable, in which the contacting element is released for transfer into the contacting position.
  • the rocker element serves to lock the contacting element in the holding position in such a way that the contacting element is held in its open position.
  • an electrical line can be inserted (for example into a plug-in opening of a housing of the connection device) without this being hindered by the contacting element, without the contacting element protruding into a receiving area for the electrical line and thus without the insertion of the electrical line difficult or even blocked. Due to the rotatable mounting of the rocker element, it can be reset into the holding position particularly easily, so that a small force can be sufficient to reset the connection device.
  • the electrical line When inserted into the plug-in opening, the electrical line interacts with a triggering area of the rocker element, so that the rocker element is transferred from its holding position into the release position.
  • the contacting element is released, so that the contacting element can be transferred from the open position into the contacting position and the connection device can thus close (automatically).
  • the contacting element urges an introduced electrical line against the conductor.
  • reliable electrical contact between the electrical line and the current conductor can be established and ensured.
  • the electrical line is electrically connected to the conductor (and optionally connected electrical or electronic components).
  • the contacting element is held securely and reliably in the open position by the rocker element. This makes it possible, in particular, to deliver the connection device in the open position, with an automatic triggering of the connection device, for example due to a shock effect or due to vibrations, being at least significantly more difficult when the connection device is transported.
  • the contacting element is formed by a spring element, in particular made of spring steel.
  • a spring element can be formed by a leg spring (acting on compression) or a tension spring (acting on tension via a tension leg).
  • the contacting element can thus be adjusted and deflected elastically in order to enable in particular an automatic closing of the connection device when an electrical line is plugged in.
  • the contacting element has a support section (eg supported in a stationary manner relative to a housing of the connection device) and a contact section, which can be deflected in a spring-elastic manner towards the support section, for contacting the electrical line with the conductor.
  • the contacting section is locked in the open position of the connection device via the rocker element.
  • the contacting section is in contacting (in particular electrically contacting) system with the electrical line, for example in order to press a stripped conductor end of the electrical line into contact with a current bar of the connection device and thus to make electrical contact with the electrical line with the current bar.
  • the contacting section is elastically tensioned relative to the support section in the open position of the contacting element.
  • the contacting section In the open position, in which the contacting section is locked via the rocker element and thus held in position, the contacting section is thus spring-mechanically biased towards the support section. If an electrical line acts on a triggering area of the rocker element and thereby unlocks the rocker element, the contacting section is released and, due to its elastic tension, automatically moves into the contacting position in order to contact the electrical line.
  • the bearing point (at least in the open position of the contacting element) is at least partially spatially arranged between the support section and the contacting section of the contacting element. This enables a flat design. Furthermore, this arrangement makes it possible for the rocker element to be arranged behind the contacting section and to encompass this with a holding section in the holding position. This enables particularly secure locking and, at the same time, unimpeded and abrupt unlocking.
  • the electrical line can be inserted into a plug-in opening of the connection device along an insertion direction. It can be provided that the bearing point is arranged at least in the holding position of the rocker element in relation to the insertion direction behind a holding section of the rocker element that holds the contacting element in the open position.
  • rocker element can be pivoted as a whole about the bearing point, in particular from the release position into the holding position and in particular without any deformation of the rocker element.
  • the contacting element is shaped as an integral component, in particular as an integral, bent sheet metal part.
  • the contacting element can, for example, be made from a spring steel and designed, for example, as a stamped and bent part.
  • the contacting element can have the shape of a leg spring.
  • the rocker element is shaped as an integral component, in particular as an integral, bent sheet metal part.
  • the contacting element and / or the rocker element can, however, also be composed of different individual parts.
  • the connecting device has an actuating element, for example in the form of a lever mounted on a housing of the connecting device such that it can be displaced along an actuating direction, for acting on the contacting element.
  • the actuating element can in particular serve to move the contacting element from the contacting position into the open position, so that by actuating the actuating element, the contacting element can be brought out of contact with an electrical line and the electrical line can thus be released from the connection device.
  • the contacting element is designed as a leg spring (or comprises a leg spring)
  • the actuating element can act, for example, on one leg thereof in order to adjust it and thereby transfer the contacting element from the contacting position to the open position.
  • the housing has a plug-in opening for plugging in the electrical conductor.
  • the plug-in opening can be arranged between the actuating element and the display element.
  • Fig. 1 shows a connection device 1 which enables an electrical line 2 to be connected.
  • the connection device 1 shown can be designed to be latched to a top-hat rail or, for example, can also be part of a plug connector.
  • the connection device 1 has a housing 10 on which a plug-in opening 100 is formed, into which an electrical line 2 can be plugged along a plug-in direction E.
  • the housing 10 delimits a receptacle 101 (in the form of a chamber) into which the electrical line 2 with a (stripped) conductor end 20 can be inserted by inserting it into the plug-in opening 100 in order to connect a conductor arranged in the housing 10 within the receptacle 101 Contact form of a current bar 13 electrically.
  • the current bar 13 comprises a connection section 132 which is used to establish an electrical connection with another component.
  • An electrical line 2 inserted into the receptacle 101 can be electrically connected to the other component via the current bar 13 (and in particular the connecting section 132).
  • Fig. 2 shows several parts of the connection device 1, which according to Fig. 1 are each arranged on, in particular in the housing 10.
  • the structure of the connection device 1 is described below with reference in particular to FIG Figures 1 and 2 described.

  • the contacting section 110 can be displaced relative to the support section 112, the bend 111 in particular bending elastically (changing its curvature).
  • the bend 111 extends in the housing 10 around a support 102 of the housing 10. This can prevent the support section 112 from being moved relative to the housing 10 when the contacting section 110 is displaced.
  • the contacting section 110 can be displaced relative to the support section 112 in that the contacting element 11 is bent in the area of the bend 111.
  • the contacting element 11 can be transferred between a contacting position and an open position and is pretensioned into the contacting position.
  • the contacting section 110 rests on the current bar 13 or an electrical line 2 arranged between the current bar 13 and the contacting section 110.
  • a stop 131 is formed on the current bar 13, here in the form of an edge formed on the bar section 130 and protruding therefrom. The stop 131 limits the adjustment range of the contacting section 110.
  • the contacting section 110 In the open position, the contacting section 110 is arranged closer to the support section compared to the contacting position.
  • the contacting section 110 is essentially flat and has an end edge with which the contacting section 110 can act on the electrical line 2 introduced into the receptacle 101 (and, if no electrical line 2 is introduced into it, against the stop 131 in the contacting position of the current bar 13 strikes). If an electrical line 2 is introduced into the receptacle 101 and the contacting element 11 is in the contacting position, the electrical line is clamped (resiliently) between the current bar 13 and the contacting element 11. In this case, electrical contact is established between the current bar 13 and the electrical line 2.

  • the axis of rotation D2 is higher (i.e. further up) than the retaining claw 120. This results in self-locking of the retaining claw 120.
  • forces due to vibrations act or the like on the connection device 1 with the contacting element 11 in the open position, then a force of the contacting section 110 on the holding claw 120 causes a torque on the rocker element 12 in a direction of deeper engagement of the holding claw 120 with the contacting section 110. This counteracts loosening and enables particularly secure mounting in the open position.
  • the triggering area 121 of the rocker element 12 serves to interact with an electrical line 2 pushed into the receptacle 101 in order to transfer the contacting element 11 from the open position to the contacting position by detaching the retaining claw 120 from the contacting section 110 so that this is due to the bias of the bend 111 on the current bar 13 moved towards.
