Description

[Technical field]

[0001] The present invention relates to a housing for at least partially covering and accommodating the conductor-side connection points of at least two contact elements, in particular a pair of contact elements, and further to housing assemblies and sets each comprising such a housing. [Background technology]

[0002] Housings of the above mentioned kind can be used to at least partially cover contact elements, which require a safety cover to provide protection against contacts and short circuits, especially high voltage contact elements, and to protect the contact elements from external influences, such as dust or moisture.

[0003] Electrical conductors, for example cables or bus bars, may be connected to the conductor-side connection points of the contact elements, which are intended to be protected by the housing according to the invention.

[0004] The contact element may be part of a charging system for an electric vehicle. For example, the contact element may be part of an on-board charging socket of an electric vehicle, which is configured to plug in a charging plug on the contact side and to connect an electric conductor on the conductor side. The arrangement of the two contact elements relative to each other may differ from application to application. This may occur, for example, when the charging plug standards are different. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE DISCLOSURE It is therefore an object of the invention to provide a housing of the type mentioned at the outset, which can be used with contact elements that are arranged differently from one another, without structural modifications to the housing. [Means for solving the problem]

[0006] This object is achieved with respect to the housing mentioned in the introduction in that the housing is configured to cover the conductor-side connection points of the at least two contact elements and to at least partially accommodate at least two electric conductors and a connection assembly for connecting the electric conductors to the contact elements, the housing comprises a first partial housing and a second partial housing which complement each other in the assembled state to form the housing, the first partial housing having a first conductor receptacle configured to at least partially accommodate the first electric conductor and a first connection assembly for connecting the first electric conductor to the first contact elements, the first partial housing further being provided with a through opening for the second contact element. The second partial housing has a second conductor receptacle configured to at least partially accommodate a second electrical conductor and a second connection assembly for connecting the second electrical conductor to the second contact element. The second partial housing is also configured to abut the first partial housing in the region of the through opening. In the assembled state, the second conductor receptacle forms a common cavity with the through opening.

[0007] Due to the fact that the housing consists of two partial housings, each partial housing configured to accommodate an electric conductor and a connection assembly for a respective one of the contact elements, the two partial housings can be arranged at least partially independently of one another and can be used for contact elements that are arranged at least partially differently from one another, while they form a common housing.

[0008] The first contact element may then project into the first conductor receptacle and may be connected there to a first electrical conductor by a first connection assembly. The second contact element may be arranged to project through a through opening in the first partial housing and may be electrically connected to a second electrical conductor disposed in the second partial housing by a second connection assembly, which is made possible by the second connection assembly forming a common cavity with the through opening when the housings are in the assembled state.

[0009] The housing according to the invention can be used for contact elements that are arranged differently relative to one another, which reduces production costs, since a separate housing does not have to be produced for each predefined relative position of the contact elements. The housing according to the invention can therefore be used universally for at least a certain range of different positions of two contact elements relative to one another. The different positions of the contact elements relative to one another can be realized in particular by mutually different spacings between the contact elements or by mutually different axial spacings of the contact elements.

[0010] The electrical conductor may in particular be a bus bar. Alternatively, other electrical conductors, in particular cables, may serve as the conductor. In particular, the ends of the electrical conductors may be arranged in corresponding conductor receptacles. The conductor receptacles may in particular be configured to partially receive the ends of the corresponding conductors.

[0011] When the connection assembly is placed in the conductor receptacle, the connection assembly may close the conductor receptacle from the outside.

[0012] The connection assemblies may, for example, have a threaded connection for screwing one electrical conductor each into the conductor end of the contact element. As an alternative, at least one of the connection assemblies may be configured to establish a connection between the conductor and the contact element, for example by clamping, plugging, pushing or crimping. A further alternative may be that the connection assembly comprises soldering or welding points. The connection assemblies may be configured to permanently or detachably connect the conductor to the contact element.

[0013] The two conductor receptacles may extend along a longitudinal axis that may coincide with a longitudinal axis of the contact element when the housing is attached over the contact element, and preferably extend parallel to one another.

[0014] The solution according to the invention can be further improved by various configurations which are advantageous alone and can be randomly combined. These configurations and their associated advantages are described below. The housing according to the invention is also described with reference to the elements accommodated in the housing, such as contact elements, electrical conductors and connection assemblies. These elements do not necessarily have to be part of the housing. The description of the elements mentioned merely serves to better illustrate the configuration of the housing described.

[0015] At least one of the conductor receptacles is preferably configured to hold the conductor along the longitudinal axis by form-fitting, for example the conductor receptacle may be provided with at least one undercut for receiving a conductor, in particular a bus bar, such that when the conductor is attached to the contact element, the partial housing is automatically secured to the contact element as well.

[0016] The through opening may have an inner diameter larger than the outer diameter of the contact element intended to protrude through the through opening. As a result, the housing according to the invention can be used for different pairs of contact elements with different spacings. As a result, a structurally identical housing can be employed, for example, when using contact elements with grids of 26 mm and 27 mm. The grid relates to the axial spacing of the longitudinal axes of the two contact elements. Such a grid is used, for example, for different charging sockets. The housing according to the invention makes it possible to avoid the need to design and produce separate housings for the two grids.

[0017] A wall, in particular a cylindrical wall, of the first conductor receptacle may protrude from the first partial housing and may be received in a receptacle in the second partial housing in the assembled state. The receptacle in the second partial housing may in particular be formed as an elongated hole, the longitudinal direction of which preferably runs transversely to the axial direction of the first conductor receptacle. The smallest inner diameter of the elongated hole particularly preferably substantially corresponds to the outer diameter of the wall, so that the wall can be received without play in the elongated hole in at least one direction.

[0018] By accommodating the wall in the slot, the second partial housing can be fixed to the first partial housing and prevented from rotating relative to the first partial housing, which can be advantageous when a connection assembly with a threaded connection in the second partial housing is manipulated.

[0019] The slot preferably extends through the second partial housing parallel to a longitudinal axis of the second conductor receptacle, the longitudinal direction of the slot extending perpendicular to the longitudinal axis and preferably parallel to an imaginary connection line between the first conductor receptacle and the second conductor receptacle in the assembled state.

[0020] In order to prevent the through opening from opening to the outside, the second partial housing may have a cover part, in particular a ring-shaped cover part, which abuts against the first partial housing in the area of ​​the through opening and is configured to cover the through opening in the first partial housing at least in its edge area.

[0021] The cover part may in particular form an abutment surface. It is particularly preferred that the cover part is formed complementarily to a part of the first partial housing which surrounds the through opening.

[0022] The outer diameter of the cover portion may be greater than the inner diameter of the through opening in the first partial housing.

[0023] In order to obtain a tight connection of the two partial housings, it is preferred that at least in the area between the through opening in the first partial housing and the second conductor receptacle in the second partial housing, the second partial housing is provided with at least one sealing element, in particular an axial sealing element, in the area of ​​the cover part.

[0024] It is particularly preferred that the first partial housing has at least one, in particular ring-shaped, bead surrounding the through-opening, which in the assembled state abuts against a cover part of the second partial housing. If the second partial housing is provided with a sealing element, the bead may be pressed against the sealing element in the assembled state. A contact pressure may be generated by the second connection assembly, which can press the second partial housing against the first partial housing when the second connection assembly or the second conductor is placed in the second conductor receptacle with a form fit and when the second connection assembly is attached to the second contact element.

[0025] As an alternative to the above-mentioned configuration, the second partial housing may be provided with a bead and / or the first partial housing may be provided with a cover portion and / or a sealing element.

[0026] In order to increase the security of the contact elements arranged in the housing, the first conductor receptacle and the second conductor receptacle are preferably separated from one another when the housing is in the assembled state, in particular the first conductor receptacle and the common cavity consisting of the through opening and the second conductor receptacle may be separated from one another by walls of the two partial housings surrounding the respective cavities. In order to obtain a simple construction and to be able to accommodate commercially available contact elements, the two conductor receptacles, preferably also at least one through opening, are formed with a substantially circular cross section, in particular the area of ​​the conductor receptacle that is configured to retain the electric conductor by its shape may differ from the circular cross section.

[0027] A housing assembly according to the invention comprises a housing according to the invention and at least one contact housing element configured to be matable with the housing, the contact housing element having a first contact element receptacle configured to define a position of the first contact element and a second contact element receptacle configured to define a position of a second contact element at a predetermined distance from the first contact element, the second contact element receptacle having an inner diameter smaller than an inner diameter of the through opening in the first partial housing.

[0028] The contact housing element can in particular function as a spacer between two contact elements and thus define the relative position of the two contact elements relative to one another.

[0029] Due to the above-defined inner diameter, the second contact element can be arranged at different positions in the through opening while being connected to the second connecting element in the second conductor receptacle, which allows the housing to be used for different relative positions of the two contact elements, the relative positions of the two contact elements being defined by the contact housing element.

[0030] A separate contact housing element may be necessary for each relative position of the two contact elements relative to one another, however, a housing of the same construction can always be used to cover the contact elements.

[0031] In the assembled state, the contact element receptacles are preferably arranged coaxially with the corresponding conductor receptacles.

[0032] The contact housing element and the housing are preferably configured to complement one another. Particularly preferably, the contact housing element and the housing can be configured to be plugged into one another. The contact housing element can be part of a housing that consists of two part housings and can be plugged in as a cover.

[0033] The housing assembly may further include at least one alignment structure disposed between the second contact element receptacle and an inner wall of the through opening in the assembled state.

[0034] The alignment structure may be arranged between the second contact element and an inner wall of the through opening, in particular without play, and may define the position of the second contact element relative to the first partial housing, i.e. in the through opening.

[0035] The alignment structure is preferably configured to be pressable into the through opening.The alignment structure may at least partially surround the second contact element receptacle.

[0036] The at least one alignment structure may be configured to be connectable to the contact housing element or may be integrally formed with the contact housing element. It is preferred that the at least one alignment structure is integrally formed with the contact housing element, in particular as part of a larger housing.

[0037] In order to define the distance from the second contact element to the first contact element particularly simply by means of the at least one alignment structure, the at least one alignment structure may have a different thickness on a side of the second contact element receptacle closer to the first contact element receptacle than on a side further from the first contact element receptacle. The thickness preferably extends along a radial direction with respect to a longitudinal axis of the second contact element receptacle, in particular parallel to an imaginary connection line between the two contact element receptacles. The alignment structure may therefore have a thickening on at least one side of the second contact element receptacle.

[0038] The thickness can be formed particularly simply by the at least one alignment structure having at least one rib on the side with the greater thickness, in particular a rib for abutting against an inner wall of the through-opening. The rib preferably extends parallel to the longitudinal axis of the second contact element receptacle. The rib may correspond to a thickening.

[0039] In addition to the housing of the above mentioned kind, the set according to the invention comprises two contact housing elements, the axial spacing between the first and second contact element receptacles being different for the two contact housing elements. Thus, the two contact housing elements can be used for assemblies in which the two contact elements are spaced apart from each other differently. For both of them, the same housing can be used, each consisting of two partial housings.

[0040] Different contact housing elements can be easily obtained by providing an alignment structure on each contact housing element, providing a thickened portion, in particular a rib, on each alignment structure, and arranging the thickened portion of one contact housing element so as to face towards the first contact element receptacle and the thickened portion of the other contact housing element so as to face away from the first contact element receptacle.

[0041] The invention will now be described in more detail by way of example with the aid of advantageous embodiments with reference to the drawings. The combination of features shown as examples in the embodiments can be supplemented by further features according to the above description, depending on the properties of the housing according to the invention required for a particular application. Subject to the above description, individual features may be omitted in the described embodiments if the effect of said features is not relevant in a particular application. The same reference signs in the drawings are always used for elements having the same function and / or the same structure. [Brief description of the drawings]

[0042] [Figure 1] 2 is a cross-sectional view of a housing according to the present invention in an assembled state with contact elements, conductors, a connection assembly and a contact housing element; [Diagram 2] 2 is a perspective view of the housing of FIG. 1, in which two part housings of the housing according to the invention are shown raised above the contact elements; FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0043] Advantageous embodiments of the housing according to the invention are described below with reference to figures 1 and 2. Here, the housing according to the invention is also described with reference to the elements accommodated in the housing, such as contact elements, electrical conductors and connection assemblies. These elements do not necessarily have to be part of the housing. The description of the elements mentioned merely serves to better illustrate the embodiment of the housing described.

[0044] The housing 1 comprises a first partial housing 3 and a second partial housing 5. In the assembled state, both partial housings 3 and 5 complement each other to form the housing 1, as shown in FIG.

[0045] Each of the partial housings 3 and 5 has a conductor receptacle. The first partial housing 3 has a first conductor receptacle 7 and the second partial housing 5 has a second conductor receptacle 9.

[0046] Each conductor receptacle 7 or 9 is preferably formed by a cavity in the corresponding partial housing 3 or 5 having a substantially cylindrical shape.

[0047] The conductor receptacle 7 is used to receive at least a portion of a first electrical conductor 11. The first electrical conductor 11 is shown in Figure 1 as a busbar 13 by way of example only. Alternatively, the first conductor 11 may be formed as a cable or another type of conductor.

[0048] A first connection assembly 15 for connecting the first electrical conductor 11 to a conductor-side connection point 17 of the first electrical contact element 9 is also housed in the first conductor receptacle 7 .

[0049] The first connection assembly 15 is shown merely by way of example as a combination of a screw 21 and a sleeve 23. The sleeve 23 may protrude into the busbar 13 and may be disposed between the busbar 13 and the first electrical contact element 19.

[0050] The screw 21 may press the busbar 13 and sleeve 23 against the first contact element 19. This may establish a stable electrical connection between the busbar 13 and the first electrical contact element 19.

[0051] The first connection assembly 15 may further include a screw head insulator 25 that protects the screw 21 from external contact. The screw head insulator 25 may be dimensioned to close the first conductor receptacle 7 from the outside.

[0052] The first conductor receptacle 7 extends along a first longitudinal axis 27. The first longitudinal axis 27 preferably coincides with a longitudinal axis 29 of the first contact element 19.

[0053] An undercut 31 preferably extends transversely to the longitudinal axis 27 from the first conductor receptacle 7 into the material of the first partial housing 3. The undercut 31 may serve to accommodate the busbar 13.

[0054] When the busbar 13 is received in the undercut 31, the busbar 13 is held in the first partial housing 3 by form-fitting and fixed against relative movement parallel to the first longitudinal axis 27. This arrangement means that the first partial housing 3 is also fixed with respect to the first contact element 19.

[0055] The second conductor receptacle 9 is preferably formed similarly to the first conductor receptacle 7. The second conductor receptacle 9 is used to receive a second electrical conductor 33, preferably formed by a bus bar 35.

[0056] The second conductor receptacle 9 further serves to accommodate a second connection assembly 37. The second connection assembly 37 may be of substantially the same structure as the first connection assembly 15. In other words, the second connection assembly 37 preferably has threads 39 configured to be screwed into the second contact element 41, particularly at the conductor-side connection point 43 of the second contact element 41. The first contact element 19 and the second contact element 41 form a pair of contact elements.

[0057] The second connection assembly 37 preferably includes a screw head insulator 45. The connection assembly 9 may include a sleeve 47 that may improve the electrical connection between the second conductor 33 and the second contact element 41.

[0058] In the second partial housing 5, an undercut 49 extends from the second conductor receptacle 9 into the material of the second partial housing 5, thereby allowing a form fit between the second electrical conductor 33 and the second partial housing 5 to be established here as well.

[0059] The second conductor receptacle 9 preferably extends along a second longitudinal axis 51 that preferably coincides with a longitudinal axis 53 of the second contact element 41 when the second connection assembly 37 is connected to the second contact element 41. The second longitudinal axis 51 preferably extends parallel to the first longitudinal axis 27.

[0060] The first partial housing 3 has a through opening 55. The through opening 55 extends along a longitudinal axis 57 through the first partial housing 3. The longitudinal axis 57 extends parallel to the first longitudinal axis 27. The longitudinal axis 57 preferably also extends parallel to the longitudinal axis 51.

[0061] The longitudinal axis 57 may coincide with the second longitudinal axis 51 and with the longitudinal axis 53 of the second contact element 41. However, this depends on the position of the second contact element 41 and thus on the position of the second partial housing 5.

[0062] The through opening 55 may be used to receive through the second contact element 41. In the assembled state, the second conductor receptacle 9 and the through opening 55 form a common cavity 59.

[0063] 1 and 2 show a situation in which the second contact element 41 and the second connection assembly 37 are disposed in a common cavity 59, so that in FIGS. 1 and 2 the common cavity 59 is blocked.

[0064] The second partial housing 5 is configured to abut against the first partial housing 3 in the region of the through opening 55, thereby forming a common cavity 59. At the same time, the through opening 55 and the second contact element 41 arranged therein can be protected.

[0065] The second partial housing 5 has a cover part 61 for abutting against the first partial housing 3. The cover part 61 is preferably ring-shaped and is arranged to cover the through-opening in the first partial housing 3 at least in its edge region 63.

[0066] The outer diameter 65 of the cover part 61 is preferably larger than the inner diameter 67 of the through opening 55. This makes it possible to ensure that the second partial housing 5 can always cover the through opening 55, regardless of the position of the second contact element 41 in the through opening 55.

[0067] Position here refers to the axial spacing 69 between the longitudinal axis 29 of the contact element 19 and the longitudinal axis 53 of the contact element 41 .

[0068] In order to obtain a connection sealed against the outside between the second partial housing 5, in particular its cover part 61, and the first partial housing 3 in the area of ​​the through opening 55, a sealing element 71 may be provided which can be arranged between the two partial housings 3 and 5 in the area of ​​the through opening 55.

[0069] One of the two partial housings 3 or 5 is preferably provided with an axial sealing element 73 which can be received in a ring-shaped receptacle in the partial housing in question.

[0070] 1 and 2, merely by way of example, the second partial housing 5 is provided with such an axial sealing element 73. In order to further improve the effect of the sealing element 71, the partial housing arranged opposite may be provided with a bead 75 which runs in the shape of a ring around the through opening 55 and which can be pressed into the sealing element 71 in the assembled state. In the example shown, the bead 75 is formed in the first partial housing 3.

[0071] As an alternative to the axial sealing element 73, the sealing element 71 may also be formed as a sealing disk or a sealing ring arranged between the two partial housings.

[0072] To prevent the second partial housing 5 from rotating about the second longitudinal axis 51 when the second connection assembly 37 is operated, the second housing portion 5 has a receptacle 77 that is spaced apart from the second conductor receptacle 9 in a direction transverse to the longitudinal axis 51.

[0073] A wall 79 of the first conductor receptacle 7 may be received in the receptacle 77 in the assembled state. The wall 79 is part of the first partial housing 3 and projects therefrom parallel to the first longitudinal axis 27.

[0074] The receptacle 77 is preferably formed as an elongated hole 81 whose longitudinal direction 83 runs parallel to an imaginary connection line 85 between the two longitudinal axes 29 and 53 of the contact elements 19 and 41 .

[0075] A housing 1 of the above kind makes it possible to accommodate or cover two contact elements 19 and 41 and can be used for different axial spacings 69 of the contact elements 19 and 41 from one another.

[0076] The second contact element 41 preferably has a diameter 87 smaller than the inner diameter 56 of the through opening 55. The contact element 41 can therefore be accommodated in the through opening 55 even with different axial spacings 69. Meanwhile, the second partial housing 5 can always abut against the first partial housing 3, thereby covering the through opening 55 and further enabling the second connection assembly 37 to fasten the second conductor 33 to the second contact element 41.

[0077] Due to the fact that the cover part 61 of the second partial housing 5 always covers the through opening 55 and due to the fact that the receptacle 77 is formed as an elongated hole 81, the second partial housing 5 can be used for different axial distances 69. The housing 1 can therefore be used universally.

[0078] In order to define the relative positions of the two contact elements 19 with respect to each other, in particular to define the spacing 90 and thereby also the axial spacing 69, at least one contact housing element 88 may be provided having a first contact element receptacle 89 for the first contact element 19 and a second contact element receptacle 91 for the second contact element 41.

[0079] Contact element receptacles 89 and 91 are used to define the location of contact elements 19 and 41. Contact housing element 88 is also preferably used to fasten contact elements 19 and 41.

[0080] Contact housing element 88 may function as a spacer for contact elements 19 and 41. Contact housing element 88 may be part of a larger housing 93.

[0081] The housing 1 and the contact housing element 88 together form a housing assembly 95 .

[0082] The second contact element receptacle 91 has an inner diameter 97 that is smaller than the inner diameter 56 of the through opening 55. The inner diameter 97 may generally correspond to the diameter 87 of the second contact element 41, thereby allowing the second contact element 41 to be received in the second contact element receptacle 91 without play.

[0083] The two parts may be aligned with each other when the housing 1 is connected to the contact housing element 88. The first partial housing 3 preferably has a circumferential edge 99 into which a collar 101 of the contact housing element 88 may be inserted. A circumferential sealing element 103 may be arranged between the collar 101 and the edge 99.

[0084] A sleeve-like wall 105 surrounding the first conductor receptacle 7 may extend in a direction from the first partial housing 3 towards the contact housing element 88 and may be received in a ring-shaped receptacle 107 in the contact housing element 88 .

[0085] The edge 99, collar 101, wall 105, and receptacle 107 may define the relative position between the first partial housing 3 and the contact housing element 88. In addition, this may define the position of the first contact element 19 with respect to the first connection assembly 15.

[0086] To determine the position between the second contact element 41 and the housing 1, the contact housing element 88 may have an alignment structure 109 that is arranged between the second contact element receptacle 91 and the inner wall 111 of the through opening 55 in the assembled state.

[0087] The alignment structure 109 is preferably configured to be pressable into the through opening 55. The alignment structure 109 may at least partially surround the second contact element receptacle 91. The alignment structure 109 may have a thickness 115 on a side 113 closer to the first contact element receptacle 89 that is different from a side 117 further from the first contact element receptacle 89 where the alignment structure 109 has a thickness 119.

[0088] In the embodiment shown by way of example, the thickness 119 at side 117 is greater than the thickness 115 at side 113. The side with the greater thickness may therefore have a thickened portion 121. The thickened portion 121 may in particular be formed by a rib 123 which preferably extends parallel to the longitudinal axis 51.

[0089] For example, when the side 117 farther from the first contact element receptacle 89 has a larger thickness 119 due to the presence of the rib 123, the spacing 90 between the two contact elements 19 and 41 is smaller than when the side 113 closer to the first contact element receptacle 89 has a larger thickness 115.

[0090] In particular in the case of thickening 121 or rib 123, depending on whether thickening 121 is arranged on side 113 or on side 117, an increase or decrease in the spacing 90 of the contact elements from one another can be achieved.

[0091] A separate contact housing element 88 may be manufactured for each type of grid of the two different spacings 90 of the contact elements 19 and 41. In contrast, the partial housings 3 and 5 of the housing 1 may be structurally identical for the different contact housing elements 88.

[0092] The housing assembly 95 described above allows for a uniform interface in the housing 93 with the same sealing element 103 for different contact spacings, i.e., axial spacings 69, of the contact elements 19 and 41. [Explanation of symbols]
