Definitions

  • the invention relates to a connection device for connecting an electrical line according to the preamble of claim 1.
  • connection devices it is desirable to enable easy connection of an electrical line. It can be advantageous here that when an electrical line is plugged in, the connection device closes automatically, i.e. a contacting element is automatically transferred from an open position to a contacting position in order to make safe and reliable contact with the electrical line plugged into the plug-in opening of the housing.
  • automatic triggering should not only be possible with a comparatively rigid electrical line, for example with a ferrule arranged on an electrical line or a wire, but also with an electrical line that is inserted into the plug-in opening of the housing with comparatively little insertion force , e.g. in the form of a stranded conductor.
  • connection device it must be taken into account here that provision can be made for the connection device to be delivered in its open position in order to enable direct connection of an electrical line within the framework of intended use.
  • the contacting element of the connection device should not be triggered, if possible, even in the event of a shock effect or vibrations.
  • the known spring-loaded terminals can typically only be reset into the open position by the action of a comparatively large force on the reset means.
  • the object of the present invention is to provide an improved connection device for connecting an electrical line.
  • a connection device for connecting an electrical line which includes a current conductor, a contacting element and a rocker element.
  • the contacting element can be moved from an open position into a contacting position in order in the contacting position to contact the electrical line, in particular electrically, with the current conductor and to lock the electrical line.
  • the rocker element is held rotatably at at least one bearing point and is designed to hold the contacting element in its open position in a holding position, wherein the rocker element can be brought, in particular pivoted, from the holding position into a release position as a result of the action of the electrical line, 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 (e.g. into a plug-in opening of a housing of the connecting device) without this being prevented by the contacting element, without the contacting element protruding into a receiving area for the electrical line and thus making it difficult to insert the electrical line or even blocked. Due to the rotatable mounting of the rocker element, it can be returned to the holding position particularly easily, so that a small amount of force can be sufficient to reset the connection device.
  • the electrical line When plugged 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 to the release position. This releases the contacting element, so that the contacting element and the connection device are transferred from the open position to the contacting position can therefore (automatically) close.
  • the contacting element pushes an inserted electrical line against the current conductor. In this way, a reliable electrical contact between the electrical line and the current conductor can be established and ensured.
  • the electrical line is electrically connected to the current conductor (and optionally to electrical or electronic components connected thereto).
  • 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 connecting device in the open position, with automatic triggering of the connecting device being at least significantly more difficult, for example due to a shock effect or due to vibrations, when the connecting device is being transported.
  • 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.
  • a further electrical line can be connected to the current bar, for example, or 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 is formed by a spring element, in particular made of spring steel.
  • a spring element can be formed by a leg spring (acting under pressure) or a tension spring (acting under tension via a tension leg).
  • the contacting element can thus be elastically adjusted and deflected in order in particular to enable 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 connecting device) and a contacting section that can be deflected resiliently toward the support section for contacting the electrical line with the current 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) contact with the electrical line, for example in contact with a stripped conductor end of the electrical line To press current bar of the connection device and thus to electrically contact the electrical line with the current bar.
  • the contacting section when the contacting element is in the open position, the contacting section is stretched elastically relative to the supporting section. In the open position, in which the contacting section is locked via the rocker element and is thus held in position, the contacting section is thus spring-mechanically prestressed 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 spring-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 spatially arranged at least in sections 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 enclose it with a holding section in the holding position. This enables a particularly secure locking and at the same time an unhindered and abrupt unlocking.
  • the electrical line can be plugged into a plug-in opening of the connection device along a plug-in direction. It can be provided that the bearing point is arranged at least in the holding position of the rocker element with respect to the insertion direction behind a holding section of the rocker element holding the contacting element in the open position. Such an arrangement enables the contacting element to be held in the open position in a self-reinforcing and thus particularly secure manner.
  • the bearing point is formed on the contacting element, e.g. in the form of a bent section. This enables a simple construction and a particularly simple assembly.
  • the 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 rocker element has at least one stop.
  • the stop can be designed and arranged in such a way that the stop strikes against the contacting element when the rocker element is in the holding position. This enables a clearly defined holding position.
  • the contacting element is formed as an integral component, in particular as an integral, bent sheet metal part.
  • the contacting element can be made of spring steel, for example, and can be designed, for example, as a stamped and bent part.
  • the contacting element can have the form of a torsion spring.
  • the rocker element is formed as an integral component, in particular as an integral, bent sheet metal part.
  • the contacting element and/or the rocker element can also be composed of different individual parts.
  • the connecting device has an actuating element, for example in the form of a pusher mounted on a housing of the connecting device so that it can be displaced along an actuating direction, for acting on the contacting element.
  • the actuating element can be used in particular 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 disengaged from an electrical line and the electrical line can thus be detached from the connection device.
  • the contacting element is designed as a leg spring (or comprises a leg spring)
  • the actuating element can act on one leg thereof, for example, in order to adjust it and thereby transfer the contacting element from the contacting position to the open position.
  • the rocker element has at least one reset area.
  • the contacting element acts on the reset region, for example when it is transferred from the contacting position into the open position, for example by means of the actuating element.
  • the reset area allows a defined reset movement with little effort.
  • the restoring area and the holding section are arranged, for example, on opposite sides of the axis of rotation of the rocker element.
  • the reset area is optionally formed by a projection.
  • the rocker element is transferred into the holding position by the action of the contacting element on the at least one reset region.
  • the rocker element has at least one bearing point which is rotatably accommodated in the bearing point of the contacting element designed as a bearing seat.
  • connection device comprises, for example, a housing in which the current conductor, the contacting element and/or the rocker element are arranged and which can form a plug-in opening through which the electrical line can be inserted, in particular for contacting the current conductor.
  • the connecting device has an actuating element with which the contacting element can be transferred from the contacting position into the open position and which can be arranged such that the current conductor is arranged at least in sections between the actuating element and the contacting section.
  • the actuating element can adjust the contacting element with a particularly large lever, which enables resetting with a particularly low expenditure of force.
  • a method of manufacturing a connector in particular a connector according to any one herein described embodiment.
  • This method is not part of the invention.
  • the method includes assembling a Rocker element on a contacting element such that the rocker element is rotatably held at a bearing point on the contacting element; and (optionally subsequently) mounting the contacting element on a conductor.
  • the mounted contacting element can be transferred from an open position into a contacting position in order to electrically contact an electrical line with the current conductor.
  • the rocker element holds the contacting element in the open position in a holding position and can be transferred from the holding position (around the bearing point) to a release position as a result of the action of the electrical line, in which the contacting element is released for transfer to the contacting position.
  • This method enables a particularly simple production of a connecting device that allows the open position of the contacting element to be securely held and a particularly smooth return from the contacting position to the open position.
  • the contacting element and the rocker element mounted on it together represent a preassembled assembly that can be connected in a particularly simple manner to other parts of the connection device, e.g. a housing.
  • connection device 1 shows a connection device 1, which enables the connection of at least one electrical line 2, in this case two electrical lines.
  • the connecting device 1 shown can be latched to a top-hat rail, but could alternatively also be part of a connector, for example.
  • the connecting device 1 has a housing 10 with two halves, with a plug-in opening 100 being formed on each half, into which an electrical line 2 can be plugged in along a plug-in direction E.
  • the housing 10 delimits a receptacle 101 on each of the two halves, into which an electrical line 2 with a (stripped) conductor end 20 can be inserted by plugging it into the plug-in opening 100 in order to be connected within the receptacle 101 to a current conductor arranged in the housing 10 To contact the form of a current bar 13 electrically.
  • the current bar 13 includes a connecting section 132 which extends from one half to the other half of the connection device 1 . Via the current bar 13 (and in particular the connecting section 132), an electric line 2 plugged into the receptacle 101 on one half can be electrically connected to an electric line 2 plugged into the receptacle 101 on the other half.
  • a connecting device can also have only one half, that is to say such a receptacle 101 .
  • the current bar 13 can be connected or connected to other components. In the following, therefore, only one half of the connection device 1 is described in more detail, it being possible for the other half to be designed analogously.
  • FIG. 2 shows several parts of the connecting device 1 according to 1 are each arranged on, in particular in the housing 10 .
  • a contacting element 11 is designed in the form of a multiply bent spring element.
  • the contacting element 11 is designed in one piece, e.g. by stamping and bending a piece of spring steel.
  • a rocker element 12 the current bar 13 (shown only in part) and an actuating element 14 are shown.
  • the contacting element 11 comprises a contacting section 110 which is connected to a support section 112 via a bend 111 .
  • the support portion 112 is in Housing 10 on a wall (see 1 ).
  • the contacting portion 110 can be displaced relative to the supporting portion 112, in particular the bend 111 elastically bends (changes its curvature).
  • the bend 111 extends in the housing 10 around a bracket 102 of the housing 10 . This can prevent the supporting 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 supporting section 112 by the contacting element 11 being 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 prestressed into the contacting position.
  • the contacting section 110 rests against the current bar 13 or an electrical line 2 arranged between the current bar 13 and the contacting section 110 .
  • a stop 131 in the form of an edge formed on the bar section 130 and protruding therefrom is formed on the current bar 13 .
  • 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 supporting section than in 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 inserted into the receptacle 101 (and which, if no electrical line 2 is inserted therein, in the contacting position against the stop 131 of the current bar 13 strikes). If an electrical line 2 is inserted into the receptacle 101 and the contacting element 11 is in the contacting position, then the electrical line is clamped (spring-elastic) between the current bar 13 and the contacting element 11 .
  • the contacting section 110 in the contacting position extends obliquely to the plug-in direction E and, starting from the bend 111, follows the plug-in direction E.
  • the end edge of the contacting section 110 thus acts as a barb.
  • the stop 131 of the current bar 13 also acts as a barb.
