Definitions
- the subject relates to a connection arrangement, in particular for electric vehicles, a charging socket and a system made up of the charging socket and the connection arrangement.
- the entire transmission path from the charging station socket to the vehicle-side charging socket to the accumulator must conduct electricity very well.
- all transitions between the individual components of the transmission link must have particularly low transition resistances.
- the object of the invention was therefore, among other things, to provide a particularly well-conducting connection arrangement and a charging socket which provide increased safety both during assembly and during operation and enable a long-term stable connection between the charging socket and the connection arrangement.
- connection arrangement according to claim 1, a charging socket according to claim 39 and a system according to claim 41.
- the subject connection assembly includes a housing.
- the housing of the connector assembly may be formed from a non-conductive material.
- the housing can be formed from a plastic, in particular from a high-temperature plastic, for example PA6GF15, UL94 or another plastic which is suitable for high temperatures. It is also possible for the housing to be made of ceramic, glass, a metal material which is coated with an insulating layer, for example, or other materials.
- the housing can be formed from a combination of several materials.
- a housing made of a mechanically resilient, first material such as a metal material is conceivable. This can absorb mechanical loads, for example.
- a further material can be provided, for example a non-conductive material such as plastic, ceramic and/or Glass.
- a combination of two materials can ensure mechanical stability on the one hand and good electrical insulation of the housing on the other.
- Materials with good thermal conductivity can also be used, at least in part.
- a housing that is formed at least partially from a metal material can provide a high thermal capacity and a high thermal conductivity to the environment. Conductive parts of the housing, in particular metal parts, are isolated from live components, for example by means of insulating coatings and/or other non-conductive components.
- connection arrangement in question comprises at least two busbars. In the following, one of the busbars is described first.
- the busbar has an essentially rectangular cross section.
- the cross section can have two broad sides lying opposite one another and essentially parallel to one another, and two narrow sides arranged essentially perpendicular thereto, essentially parallel to one another and lying opposite one another. At least one of the narrow sides is in particular perpendicular to at least one of the broad sides.
- the busbar has at least partially a longitudinal axis. This runs essentially perpendicular to both the narrow and the broad sides.
- the broad side is wider perpendicular to the longitudinal axis than the narrow side.
- a breadth dimension may be defined as the axis perpendicular to the longitudinal axis and parallel to the broadside.
- a front side can also be defined.
- the longitudinal axis can form at least partially essentially the surface normal.
- the bus bar is formed from an electrically conductive material, for example a metal material.
- the conductor rail can be formed from copper, aluminum, alloys thereof and/or from other metal materials.
- the conductor rail can be formed from soft-annealed aluminum.
- Aluminum is light, which is a great advantage for use in vehicles. In addition, aluminum is cheaper compared to copper.
- the busbar can also be formed from a different material, in particular a different metal material such as copper.
- the conductor rail can be at least partially coated, for example with silver, gold, nickel and/or alloys thereof and/or multi-layer arrangements of these and/or combinations of these metal materials, for example with a silver coating coated with nickel.
- a conductor rail has the advantage that it provides good conductivity for heat and electricity due to its solid construction with large cross sections.
- the thermal capacity is high, particularly due to the volume of the busbar. Due to the increased surface compared to round conductors with the same cross-sectional area, more heat can also be radiated over the surface of the busbar.
- At least one of the busbars can have a cross section of at least 50 mm 2 , preferably between 100 and 300 mm 2 . Larger cross sections are also possible if a particularly high electrical output and/or a particularly large amount of heat has to be transported.
- At least one of the busbars can have a side recess. This side recess can be on one side of the. Busbar can be arranged so that the side recess interrupts the otherwise mostly straight course of the longitudinal edge.
- the longitudinal edge is in particular the edge between a broad side of the busbar and an adjoining narrow side of the busbar.
- the side recess can have a constant shape along the surface normal to one of the broad sides of the busbar.
- the edge of the lateral recess can extend at least on one side of the lateral recess essentially perpendicularly to the longitudinal edge, starting from the latter and into the conductor rail when the broad side is viewed from above. Both sides of the side recess can also extend into the busbar essentially perpendicularly to the longitudinal edge. Other edge profiles of at least one side of the side recess are also possible.
- the side recess can have one or two edges that are inclined in relation to the narrow side when the broad side is seen from above.
- at least one of the edges of the side recess can be at an angle of 30-60° relative to the narrow side.
- one edge can run essentially perpendicularly and the other at an angle to the longitudinal edge.
- the side recess can be shaped in such a way that it forms a hook and/or an undercut when viewed from above on the broad side.
- the side recess can be essentially angular in shape, for example quadrangular.
- the side recess can also be rounded, for example it can be shaped essentially in the form of a semicircle.
- a shape of the lateral recess as a quadrant is also possible.
- a side recess can be used to lock the power rail in a holder provided for this purpose.
- a latching element of the connection arrangement can thus engage in the side recess.
- An otherwise movable element for example a screw element, can also engage in the lateral recess.
- the busbar can be overmoulded by a holding element, for example plastic, in particular at least parts of the housing. This can engage in the side recess.
- the connection arrangement can comprise at least one holding means for at least one of the busbars.
- the connection arrangement can engage in the lateral recess of the conductor rail, in particular by means of the holding means.
- a latching element for example a latching lug, can engage in the side recess.
- the holding means can in particular enter into a form fit with the busbar, in particular with the side recess of the busbar.
- the holding means can in particular be mounted elastically in relation to the housing and can in particular be deflected into the lateral recess.
- the conductor rail can therefore latch with the holding means, in particular in a form-fitting manner.
- the holding means can be formed as a resilient element which can snap resiliently behind a recess in the conductor rail, in particular in a side recess.
- the holding means can be pivoted essentially transversely to the longitudinal axis of the busbar, in particular elastically deformable radially outwards, so that the holding means can bend radially outwards when the busbar is pushed in, the busbar can slide past the holding means and the holding means can then slide behind a recess in the conductor rail, in particular can spring back into a side recess.
- the holding means is not destroyed during the assembly of the busbar.
- Non-destructive unlocking of the holding means and/or the conductor rail from the holding means can also be possible with suitable aids. This may be necessary, for example, in the event of damage/service or the like, in order to replace the housing and/or the power rail.
- the holding means have an expanding receptacle for an expanding tool.
- the spreader mount can be reached, for example, through the assembly opening.
- the spreader mount can also be arranged laterally on the housing transversely to the longitudinal axis of the busbar. With the spreading tool, a spreading force acting radially outwards can be exerted on the holding means. This allows the Retaining means are removed from the side recess of the power rail and the
- Busbar can be removed from the housing in the opposite direction to the insertion direction.
- the holding means can also be formed in a substantially rigid manner.
- the retaining means may be formed as a rigid boss within the housing which is shaped to engage the side recess of the busbar.
- the cross section of the holding means in the direction of the surface normal to the broad side of the conductor rail can be at least partially adapted in cross section to the side recess and/or the cross section of the side recess.
- the busbar can be pushed onto the holding means in the direction of the surface normal on at least one of the broad sides of the busbar, in particular so that the holding means engages at least partially in the side recess.
- the holding means can extend in the direction of the surface normal to the broad side of the busbar over at least part of the height of the housing interior.
- a distance between the inner wall of the housing and the holding means can be provided in this direction on the side of the mounting opening of the housing.
- the conductor rail can be pushed in through the distance in the longitudinal axis in a region of the housing near the mounting opening without being impeded by the holding means.
- the busbar can be pushed onto at least one of the broad sides of the busbar in the direction of the surface normal and/or onto the holding means in the insertion direction of the at least one connecting bolt, so that the latter engages in the side recess of the busbar.
- the conductor rail can be prevented from slipping out of the connection arrangement along the longitudinal axis by the holding means. To remove the busbar from the holding means, it is sufficient to pull it out of the holding means in the direction of the surface normal to the broad side of the busbar, in particular in the direction of the assembly opening.
- the side recess of the power rail helps to ensure better grip compared to its immediate surroundings.
- At least one of the busbars has a lateral recess on the side facing away from the other busbar, in particular on the narrow side facing away from the other busbar.
- the at least two busbars are led into the housing.
- an end section can be defined for each of the busbars. This is the part of the power rail that is inside the housing.
- the end section can be arranged within the convex envelope of the housing.
- the end section can be the end of a busbar that has been cut to length.
- the end section of the busbar, which has been cut to length, encompasses the end face of the busbar.
- the end section can also be a central area of a busbar, which is located in the housing.
- the at least two busbars are fixed in the housing.
- the busbars are fixed relative to one another, in particular at a distance from one another.
- the busbars are also fixed relative to the housing.
- the housing can fix the busbars directly or indirectly.
- the busbars can be held essentially rigidly by the housing. A change in the position of one of the busbars relative to another busbar and/or relative to the housing is therefore only possible by deforming the housing.
- An at least partially elastic fixation of the busbars by the housing is also possible.
- a partially elastic fixation can allow a movement of the busbar along a spatial direction, for example along the longitudinal direction of the busbar.
- An elastic fixation can also allow the busbar to tilt about an axis, for example around the longitudinal axis of the busbar.
- At least one of the busbars in the housing can also be formed by a housing part made of a material that can withstand mechanical loads, for example made of a metal material, in particular made of an insulated metal material.
- connection arrangement comprises at least two busbars.
- connection bolt is arranged in each of the at least two busbars.
- the terminal bolt has a joining area that extends from a first end face to a central area, and a contact area that extends from a second end face to the central area.
- the connecting bolt can be arranged in an opening in the busbar.
- the opening in the conductor rail extends from a first broad side to the second broad side of the conductor rail, which is opposite the first broad side.
- the opening can be shaped as a through hole, for example.
- the through hole may have a substantially round cross section.
- An elliptical, angular, in particular triangular, quadrangular, pentagonal, hexagonal, polygonal, jagged or otherwise shaped cross section of the through hole is also possible.
- the through-hole can have a substantially constant cross-section along the thickness of the busbar, or it can also be variable Cross-section.
- the through hole can taper from a first to a second broad side.
- connection bolts are made of an electrically conductive material.
- the connecting bolt can be formed from a metal material, in particular copper, e-copper, aluminum, alloys thereof and/or other metal materials. At least partial or also complete coating of the connection bolt is also possible; Thus, the connection bolt can be coated with silver, gold, nickel and/or alloys and/or combinations thereof.
- the connecting bolt can be formed from copper, in particular E-copper, and at least partially, in particular essentially completely, be provided with a silver coating plated with nickel.
- At least one of the or the at least two connecting bolts can be arranged centrally on the broad side of the busbar in relation to the central axis of the broad side of the busbar.
- the central axis can run centrally in the broad side along the longitudinal direction of the busbar, so that it is essentially the same distance from the two narrow sides.
- the connecting bolt can also be arranged on the busbar decentrally and/or eccentrically in relation to the central axis of the busbar.
- At least the joining area of the connection bolt can lie within the broad side of the conductor rail in a plan view of the broad side of the conductor rail.
- the contact area of the connecting bolt can protrude beyond the broad side of the busbar in a plan view of the broad side.
- the connecting bolt in particular the contact area, also lies completely within the broad side in the top view of the broad side.
- the position of the at least two connection bolts of the at least two busbars in relation to one another can be specifically selected. In particular, their position can be defined for at least two busbars fixed in the housing of the connection arrangement.
- the at least two connection bolts of the at least two busbars can be arranged essentially at the same position along the longitudinal axis of at least one of the busbars.
- the terminal bolts can each have essentially the same distance from the end face of the conductor rail to which they are connected.
- the connection bolts can also be offset from one another along the longitudinal axis, in particular spaced apart.
- one of the terminal bolts can be closer to the face of the busbar to which it is connected than another terminal bolt.
- the two busbars can essentially lie in one plane.
- One of the busbars can also be offset in the direction of the surface normal and the broad side of at least one of the busbars relative to the at least one other busbar.
- connection bolts of the at least two busbars can essentially protrude the same distance out of the respective busbar to which they are connected.
- the connection bolts can also protrude to different extents from the respective busbar to which they are connected.

- the seal can have one, two or more individual ribs and/or sealing lips.
- a plurality of ribs may run along the full circumference of the gasket.
- Ribs have the advantage of a better sealing effect compared to seals without ribs and/or with only one rib.

- one of the two housing parts can have an elevation which engages in a recess on the respective other housing part.
- Holding means can also connect the two housing parts, upper and lower, to one another.
- a multi-part design of the housing part has the advantage that the housing part does not have to be pushed onto the busbars along the longitudinal axis of the busbars, but can be placed laterally. This is particularly important if the course of the busbar is not straight and also if a connecting bolt is already attached to at least one of the busbars. In this case, it is not possible to slide the housing part along the longitudinal axis of the busbar, for example starting from the end face of the busbar.

- a respective lateral surface for a busbar and/or a connecting bolt and/or a lateral surface between the busbars can prevent accidental contacting of the busbars with one another using a tool such as a screwdriver made of a metal material.
- a lateral surface can also be arranged around one of the partial openings, while the other has no lateral surface of its own. Such an asymmetrical arrangement of lateral surfaces can enable the connecting bolts to be secured selectively. For example, only the positive pole of a pair of charging lines (the busbars) can be protected in this way, while the negative pole remains easier to reach at ground potential than the positive pole. A fitter can also be informed in this way which assembly sequence is to be selected.

- the retaining means for the assembly opening closure can be arranged below the assembly opening. This can mean that the holding means are arranged at a distance in front of the assembly opening in the direction of gravity in the connected state of the connection arrangement. It can thus be achieved that the opened assembly opening closure, driven by gravity, tends to move away from the assembly opening. This does not interfere with access to the mounting opening. Lower demands can also be placed on the holding means as these don't need to hold the mounting hole fastener tightly in one position, just loosely keep it from falling.

- the assembly seal can be arranged at least partially on a lateral surface of the assembly opening of the housing, for example on the outer wall and/or on the inner wall and/or an end face of a lateral surface of the assembly opening.
- the assembly seal can be arranged circumferentially around the assembly opening. If the assembly opening seal covers the assembly opening, the seal can contact both the assembly opening seal and the housing, in particular contact circumferentially.

- a securing means can be arranged in the assembly opening.
- a fuse can be arranged, which is set up in such a way that it de-energizes the busbars as long as the assembly opening is open. When the assembly opening lock is open, the fuse can therefore ensure that the busbars are free of voltage.

- the diameter of the joining area is therefore at least partially larger than the diameter of the opening of the busbar, in particular in a section facing the contact area, and/or at least partially smaller than the diameter of the opening, in particular in a section facing away from the contact area.
- welding energy in particular by means of friction welding, in particular rotary friction welding, pressure butt welding, ultrasonic welding, etc., can be introduced into the connection between the connecting bolt and busbar, so that parts of the busbar and/or parts of the connecting bolt plasticize.

- the contact area of at least one or at least two connecting bolts is tapered in such a way that the lateral surfaces, the outer of the contact area of the connecting bolt and the inner of the recess, lie against one another, in particular lie against one another essentially over the entire surface.
- the contact area of the respective connecting bolt can therefore be adapted to a recess. This minimizes the contact resistance between the charging socket and the connection part.

- Guide elements can limit the freedom of movement of the busbar, in particular in the direction of the surface normal on at least one of the broad sides of the busbar, in the direction parallel to the longitudinal axis of the busbar towards the end face of the busbar and/or parallel to the broad side perpendicular to the longitudinal axis.
- Retaining means are designed in particular to counteract a movement of the busbar parallel to the longitudinal axis out of the housing,
- a guide element can be formed as a guide element on both sides. This comprises a bearing surface which faces the broad side on the receiving opening side, and a bearing surface which faces the broad side of the conductor rail on the assembly opening side.
- the distance between the two bearing surfaces can in particular essentially correspond to the thickness of the busbar and/or the width of the narrow side. The freedom of movement of the conductor rail is thus restricted both in the direction of the assembly opening and in the direction of the receiving opening.

- the bearing surfaces of the guide element on both sides can be formed by the projections.

- a guide element can be a one-sided guide element for this purpose.
- a one-sided guide element has at least one bearing surface on the side of the busbar that faces the receiving opening.
- the busbar can rest with the receiving opening-side wide side on the at least one bearing surface of the one-sided guide element.
- the contact surface can do this in the Wide side of the busbar, protrude essentially parallel to the wide side of the busbar. In this way, the conductor rail cannot overcome the guide element, more precisely its bearing surface, in the direction of the receiving opening and/or in the plug-in direction of the connecting bolt.
- the one-sided guide element preferably does not or only slightly restrict the movement of the busbar in the direction of the surface normal to the broad side of the busbar.
- the one-sided guide element preferably does not protrude into the other broad side.
- the one-sided guide element can at least partially restrict the freedom of movement of the busbar.
- it can have at least one bearing surface that faces a narrow side of the busbar. This bearing surface keeps the busbar from moving parallel to the broad side of the busbar perpendicular to the longitudinal axis of the busbar, ie parallel to the surface normal to the narrow side.
- a guide element can be formed as a click element.
- a click element can have a first support surface for the broad side of the busbar on the receiving opening side.
- This first bearing surface can be formed, for example, similarly to the bearing surface of the one-sided guide element.
- This second support surface can be formed, for example, by a resilient element.
- a resilient element relative to the wall of the housing of the connection arrangement can oppose a deformation in the direction of the housing wall with an elastic restoring force.
- the resilient element can be formed by an element which, starting from a fastening point on the assembly opening side, extends in the direction of the receiving opening essentially in the direction of the surface normal to the broad side of the conductor rail and pointing away from the housing wall.
- the power rail can come from the attachment point, the resilient element in the direction of the wall deform. After passing the resilient element, it snaps back on the wide side of the conductor rail on the assembly opening side.

- the at least one guide element of at least one of the busbars and the holding means of the busbar can act, for example, on opposite sides of the busbar, for example on opposite narrow sides.
- a guide element can also be provided on the end face of at least one of the busbars.

- the holding means may or may not allow subsequent pulling out along the longitudinal axis of the busbar. For example, this can be determined, among other things, by the shape of the side recess and/or the holding element. For example, a recess with a semi-circular or otherwise at least partially rounded shape can allow extraction. A cutout with, for example, an angular, for example rectangular, cross-section, on the other hand, can make it difficult to pull out. Also, the shape of the retaining means engaging the recess may make extraction more difficult or easier.

- the holding means can also have a rounded shape and thus make it easier to pull the busbar out of the connection arrangement.
- At least one of the holding means and/or the guide elements can be designed to be essentially rigid, so that the conductor rail can only move to a very limited extent when it is connected to the guide element and/or is held by the holding means.

- a rigid connection of the busbar with another element for example with a
- connection arrangement housing Screwing the connecting bolts with recesses of a charging socket, the latter can also be fixed by the rigid connection of the busbar to the connection arrangement housing. The number of fastening operations required during assembly is thus reduced to a minimum.
- a busbar with a connecting bolt connected to it is significantly more difficult to connect to a connection arrangement than a simple flat busbar without a connecting bolt.
- the housing cannot withstand the resulting temperatures.
- manufacturing in this way would be expensive.
- the housing part is proposed, among other things, which guides the conductor rail into the housing of the connection arrangement in a sealed manner.
