Definitions

  • the present invention relates to a cable connection box for electrically connecting wires of a connection cable with further electrical lines on an electrical device.
  • Cable junction boxes of the type mentioned at the beginning are basically known from the prior art.
  • Such cable junction boxes have a housing in which several contact points or connection points are provided for connecting any wires of a corresponding connection cable.
  • the cable is usually led into the housing of the cable junction box via a strain relief.
  • the connection points are usually provided by means of screw contacts.
  • the individual wires are inserted into the corresponding connection points and electrically and mechanically connected to a contact element of the connection point by means of screws.
  • the strain relief serves to mechanically relieve the electrical connection points. After the wires have been electrically connected and the strain relief is closed, the housing can be closed and the electrical contact points can thus be safely hidden from contact.
  • Cable junction boxes therefore differ from simple connection and connecting terminals not only in their structure, intended use and size, but also in their property that their housing can be opened and closed as desired in order to optionally expose the contact points, as well as in their basically detachable connection points and often also in their optional strain relief.
  • the cable connection boxes described above are attached to a fastening area of an electrical device on the device side, usually with a defined hole pattern for clearly inserting the cable connection box.
  • the corresponding electrical cables of the electrical device are then connected to the corresponding contact elements on the back of the fastening area.
  • the respective wires of the connection cable can thus be electrically connected to the electrical cables via the contact elements.
  • the cable connection box can also have an earthing contact, by means of which the cable connection box is or can be connected to the electrical device, for example via one of the contact elements for earthing.
  • the electrical contacting of the wires usually provided as a screw connection, enables secure electrical contacting, although this is complex to install.
  • screwless contact points are also known from the state of the art, such as contact clamping areas designed as cage terminals. These can be moved into an open position using a tool, such as a screwdriver, by inserting the tool into an opening in a housing section that accommodates the cage terminal, so that a corresponding wire of a connecting cable can then be inserted into the contact point. By removing the tool, the inserted wire is then clamped in the contact point.
  • a tool such as a screwdriver
  • Such cable connection boxes therefore also require the use of a tool to insert a wire, and also require a lot of space for the cage terminal.
  • the present invention relates to a cable connection box for electrically connecting wires of a connection cable to further electrical lines on an electrical device.
  • the cable connection box has a housing.
  • the housing in turn has a housing base and a housing cover, which can be optionally closed to enclose a connection space and can be optionally opened to expose the connection space for connecting the wires of the connection cable.
  • the housing also has a cable feedthrough for feeding the connection cable into the connection space in a feedthrough direction.
  • the cable connection box also has at least one spring-loaded terminal connection with at least one conductor clamping point for electrically connecting at least one of the wires of the connection cable in a plug-in direction.
  • the spring-loaded terminal connection in turn has a contact element with a contact section for establishing electrical contact with the at least one wire in the connection space.
  • the spring-loaded terminal connection also has a clamping spring with a movable clamping leg. The clamping leg, in turn, pushes towards the contact section with a clamping edge in order to form the conductor clamping point in between.
  • the spring-loaded clamp connection is designed for tool-free connection of at least one wire via the conductor clamping point.
  • connection box By means of the cable connection box described above and in particular the use of a corresponding spring clamp connection in it, it is possible to With the aid of other aids and tools, such as a screwdriver or pushers or pivoting release levers and the like provided in the cable connection box, the wires of a connection cable can be connected electrically (and preferably also mechanically) - i.e. without tools. Since this property is provided in the spring-loaded terminal connection itself, a simple and compact design of the cable connection box can be made possible. Likewise, connecting a connection cable can be made considerably easier in this way.
  • the cable connection box according to the invention can also be used in direct exchange with known cable connection boxes, since their external structure is preferably not impaired by the use of a spring-loaded terminal connection.
  • the housing or at least its lower housing part preferably extends essentially in a plane of extension, which is more preferably aligned parallel to the feed-through direction. This allows an overall flat and thus compact design of the cable connection box to be achieved.
  • the insertion direction is preferably inclined relative to the housing base.
  • the insertion direction is inclined relative to the feed-through direction when viewed from the side or relative to the extension plane, if present. This inclination can improve the accessibility of the conductor terminal point and thus make connecting a wire easier.
  • the height of the spring-loaded terminal connection can be made more compact in this way, resulting in an overall compact design of the cable connection box.
  • the insertion direction is preferably directed diagonally towards the housing base and preferably away from the cable feedthrough.
  • the accessibility of the conductor terminal point is particularly favorable; particularly preferably in relation to the cable feedthrough.
  • the connection of a connection cable can be made significantly easier.
  • the spring-loaded terminal connection can be designed to be particularly compact, which leads to a compact design of the cable connection box overall.
  • the clamping leg can preferably be moved between a clamping position in which the clamping edge rests against the contact section and a release position in which the clamping edge is spaced from the contact section for inserting and removing the at least one wire therebetween.
  • the defined mobility and the defined movement or pivoting positions enable a high level of operating comfort with a high level of operating safety. This means that a simple and effective electrical connection of the corresponding wires of the connecting cable is possible.
  • the contact section and the clamping leg can preferably at least partially laterally delimit an insertion channel for inserting the at least one wire, which extends in the insertion direction at least as far as the conductor clamping point. In this way, a wire of the connecting cable to be inserted can be guided safely to the conductor clamping point and consequently safely into contact with the contact section for electrical contact.
  • the contact section and the clamping leg can converge towards each other in the insertion direction towards the conductor clamping point. In this way, a type of insertion funnel is provided, enabling an effective connection of the wire in the conductor clamping point.
  • the clamping spring preferably has at least one or two limiting legs which extend from the clamping leg laterally or on both sides of the insertion direction beyond the contact section. These limiting legs provide a simple but effective means of inserting a wire in a defined manner. This is all the more true when the limiting legs are provided on both sides with respect to the insertion direction.
  • the two limiting legs are preferably connected to one another via a connecting leg on the side of the contact section facing away from the conductor clamping point, in order to form a closed through-opening in the clamping spring together with the clamping leg.
  • This provides a type of window opening which enables a wire of a connecting cable to be inserted effectively. Since this window surrounds the contact section, effective electrical contacting of the wire when it is inserted towards the conductor clamping point can be made in a simple manner.
  • the connecting leg can preferably have a manipulation section, via which the clamping spring can be moved or pivoted accordingly.
  • the conductor clamping point can be opened in a simple manner; for example, in order to selectively remove a wire of a connected connecting cable that has been inserted into the conductor clamping point.
  • the clamping edge can be aligned with the through-opening when viewed in the direction of insertion and can particularly preferably be arranged downstream of it. This defined arrangement of through-opening and clamping edge enables highly effective contacting of a corresponding wire in the conductor clamping point and thus at the contact section.
  • the contact element can have a connection section which protrudes outwards from the housing or the housing base for electrical connection to further electrical lines on an electrical device; this is preferably directed from the housing base to one side away from the housing cover when the housing is closed.
  • the cable connection box can be electrically connected to an electrical device in a simple manner.
  • the cable connection box can be inserted into a defined hole pattern on the electrical device side in a known manner and electrically connected to the further electrical lines on the electrical device on the back of the hole pattern (for example provided in a mounting plate).
  • a connection cable - or more precisely its wires or conductors - can then be connected easily and without tools using the spring-loaded terminal connections.
  • connection section is preferably designed as a flat plug tongue.
  • the connection section can thus be provided in a particularly simple manner and in a known form. This means that the cable connection box can be used in a wide variety of ways.
  • the housing lower part can preferably have a receiving section for each spring clamp connection for receiving and particularly preferably for locking the associated spring clamp connection.
  • the element received in the receiving section, namely the spring clamp connection can be provided in a safe and stable manner.
  • the simple possibility of receiving the spring clamp connections enables simple assembly and preferably also automated assembly of the cable junction box.
  • the receiving section is preferably designed in such a way that the spring-loaded terminal connection can be received from an outside of the housing facing away from the connection space. This simplifies the assembly of the cable connection box and can preferably also be carried out particularly easily in an automated manner; this is all the more in the presence of an earthing contact, as described below, which is usually also mounted on the outside of the housing.
  • the housing lower part preferably the receiving section if present, can have an insertion opening arranged upstream of the conductor terminal point with respect to the insertion direction for inserting the at least one wire to the conductor terminal point. This further simplifies the insertion of a wire of a connecting cable to the conductor terminal point.
  • the insertion opening preferably runs towards the conductor terminal point. This enables a targeted and therefore effective insertion of a corresponding wire.
  • the insertion opening is preferably aligned with the insertion channel when viewed in the direction of insertion.
  • the insertion opening and the insertion channel together thus enable a highly effective insertion of a wire of a connecting cable.
  • the cable junction box can also have a grounding contact which is electrically connected to the or one of the spring clamp connections or its contact element. In this way, the cable junction box can be easily and safely grounded to the electrical device.
  • the cable junction box can thus be provided in a highly safe manner.
  • the grounding contact is preferably designed integrally with the associated spring clamp connection or its contact element. This reduces the number of components and simplifies handling for assembly. In particular, in the case where the spring clamp connections can be received from the above-described outside or underside of the housing, automated assembly of the cable connection box can be made possible in a simple manner. In particular, the grounding contact is automatically provided with the associated spring clamp connection due to its integral design.
  • the clamping spring is preferably mounted in the housing and/or in the contact element. Depending on the design of the clamping spring, it can be mounted in any and particularly advantageous manner, so that in particular simple operation and thus easy tool-free connection of wires in the conductor terminal point is possible.
  • the contact element is preferably designed as a punched and bent part.
  • the clamping spring can also be designed as a punched and bent part.
  • the cable junction box preferably has a large number of spring-loaded terminal connections. This means that any number of conductor terminals can be provided depending on the respective purpose of the cable junction box (for example, for connecting to electrical devices with high current).
  • the insertion directions of the several spring clamp connections are preferably all aligned parallel to each other. This makes it particularly easy to connect the connection cable.
  • the cable connection box can be designed to be particularly compact.
  • two of the rear spring clamp connections are arranged downstream of one of the front spring clamp connections when viewed in the insertion direction or in the feed-through direction.
  • the two rear spring clamp connections - particularly preferably with regard to their insertion direction or with regard to the feed-through direction - are arranged laterally next to one another in such a way that the receiving sections receiving them form a gap between them, which is aligned downstream of the conductor terminal point of the front spring clamp connection when viewed in the insertion direction, in order to receive a wire end of a wire of the connection cable inserted into the conductor terminal point of the front spring clamp connection.
  • the receiving sections can thus preferably be provided in a highly compact manner, nested inside one another, in order to provide an overall particularly compact design of the cable connection box. Since the gap is formed by the receiving sections, the corresponding wire end of the front spring clamp connection can be received safely and securely in it.
  • the housing can preferably also have a strain relief for locking the connection cable guided through the cable feedthrough in the cable connection box.
  • a strain relief for locking the connection cable guided through the cable feedthrough in the cable connection box.
  • the strain relief can preferably have a strain relief bracket, which is particularly preferably pivotable in the housing (for example the housing lower part) between an open position in which the strain relief or the cable feedthrough is exposed for inserting a connection cable, and a closed position in which the cable feedthrough is (at least partially) closed (for example by the strain relief bracket clamping an inserted connection cable with the housing (for example the housing lower part).
  • the strain relief can thus be designed simply but effectively.
  • the strain relief bracket can preferably lock (releasably) to the housing in the closed position, whereby the strain relief is effectively secured.
  • the strain relief can preferably also have clamping sections of the housing, for example of the housing lower part and the housing cover, and particularly preferably also of the strain relief bracket (then for example at least through the housing lower part and strain relief bracket) in order to hold or lock a connection cable guided through the cable duct in the cable connection box at least when the housing is closed.
  • the corresponding clamping sections can be distributed accordingly on the housing lower part and the housing cover or the strain relief bracket in such a way that a connection cable guided through the cable duct can be locked in the cable connection box when the housing is closed.
  • the clamping sections can be provided at least partially in the area of or in extension of the cable duct at least when the housing is closed; preferably limit the cable duct at least partially laterally or on both sides (i.e. top and bottom).
  • the strain relief can thus be provided in a particularly simple but effective manner.
  • the strain relief or at least the strain relief bracket can be manufactured integrally with the housing; this is preferably done as a (plastic) injection-molded part.
  • the clamping sections can be provided in an injection-molded manner distributed over the two housing parts.
  • a correspondingly provided strain relief bracket can be formed, for example, via a section of smaller cross-section that is also injected, which can serve as a joint section, for example.
  • a strain relief bracket is, for example, integrally injected with the housing and then separated from the housing via predetermined breaking points after the injection-molded process in order to then be connected to the housing for the preferred pivoting provision. This means that the housing and strain relief can be manufactured in a particularly simple manner, while enabling a high level of functionality and variability.
  • the housing is preferably manufactured as a (plastic) injection-molded part and particularly preferably as an integral (plastic) injection-molded part.
  • the housing can thus be manufactured in a simple manner.
  • the housing is preferably made of an insulating material (e.g. plastic) and particularly preferably using a plastic injection molding process. This means that the housing can be provided in a particularly simple manner and allows the cable connection box to be used safely.

  • the respective spring force terminal connection 6 further comprises a clamping spring 8 with a movable clamping leg 80, which presses with a clamping edge 81 towards the contact section 70 in order to form the conductor clamping point K therebetween.
  • the clamping spring 8 can be mounted in the contact element 7 (as shown in the illustrated embodiment) and/or in the housing 2.
  • the clamping spring 8 is preferably mounted only in the contact element 7.
  • the clamping spring 8 is suspended in a holding section 75 of the contact element 7 with a contact leg 85 facing away from the clamping leg 80 or the clamping edge 81.
  • Clamping leg 80 and contact leg 85 are connected to one another here via a spring arch 86, so that the clamping leg 80 can be pivoted via the spring arch 86 relative to the contact leg 85 mounted in the contact element 7 relative to the opening of the conductor clamping point K.
  • the contact leg 85 could also or alternatively be mounted in the housing 2 or the housing lower part 3.
  • the clamping spring 8 can be designed as a stamped and bent part.
  • the clamping spring 8 is preferably designed in one piece so that the clamping leg 80 and the contact leg 85 are connected in one piece via the spring arch 86, as can be seen in particular in Figures 14 and 15.
  • the clamping leg 80 can preferably be movable between a clamping position (cf. Figures 5 and 6 and 14 and 15), in which the clamping edge 81 rests against the contact section 70, and a release position (cf. Fig. 12), in which the clamping edge 81 is spaced from the contact section 70 for inserting and removing the at least one wire L therebetween.
  • the clamping spring 8 can have at least one or two limiting legs 82, which extend from the clamping leg 80 laterally or on both sides of the insertion direction E beyond the contact section 70, as can be seen in particular from Figures 14 and 15.
  • the two limiting legs 82 can, as can be seen in particular from Figure 14, preferably be connected to one another on the side of the contact section 70 facing away from the conductor clamping point K via a connecting leg 83, in order to form a closed through-opening 84 in the clamping spring 8 together with the clamping leg 80.
  • the clamping spring 8 and in particular its connecting leg 83 can have or form a manipulation section 87, via which the clamping leg 80 can preferably be moved into the release position.
  • the manipulation section 87 can, for example, be designed as a structural section in order to positively receive a tool in the direction of the release position.
  • the clamping edge 81 can be arranged in alignment with the through-opening 84 and preferably downstream thereof, as seen in the insertion direction E.
  • the contact section 70 and the clamping leg 80 preferably delimit an insertion channel C extending in the insertion direction E at least as far as the conductor clamping point K for inserting the at least one wire L at least partially laterally, as can be seen in particular from Figure 14.
  • the contact section 70 and the clamping leg 80 preferably run towards each other in the insertion direction E towards the conductor clamping point, and thus preferably form a type of insertion funnel, as can be seen for example in Figures 14 and 15.
  • the housing lower part 3 and preferably the receiving section 30 can preferably have an insertion opening 31 arranged upstream of the conductor terminal point K with respect to the insertion direction E for inserting the at least one wire L of the connecting cable to the conductor terminal point K.
  • the insertion opening 31 can be designed, for example, as a recess or opening in the housing 2 or the housing lower part 3 or the receiving section 30.
  • the insertion opening 31 preferably runs towards the conductor terminal point K, as can be seen, for example, in Figures 5 and 6.
  • the insertion opening 31 can also serve as a stop 37 for a conductor or a corresponding wire to be inserted, against which the stripped part of the wire can pass, while the insulation comes to rest there, seen in the insertion direction E, as is shown by way of example in Figures 10 to 13.
  • the insertion opening 31 can particularly preferably be aligned with the previously described insertion channel C when viewed in the insertion direction E, as can be seen, for example, in Figures 5 and 6.
  • the insertion direction E is, as can be seen in particular from Figures 5, 6 and 10 to 16, inclined with respect to the housing lower part 3; preferably with respect to the feed-through direction D as seen in side view or with respect to the extension plane P.
  • the insertion direction E can be directed obliquely towards the housing lower part 3 and preferably away from the cable feed-through 5.
