Description

Technical Field

[0001] The present invention relates to a device for attaching an electrical insulator sleeve to an electrical conductor. Furthermore, the present invention also relates to an electrical flat conductor and / or busbar having such an attached insulator sleeve, for example for use in automotive applications with a voltage range of 400 to 800 V DC. Background Art

[0002] In automotive and power engineering, electrical modules, such as battery modules, are connected via highly flexible electrical conductors to carry electrical current. For electrical safety reasons, these conductors are often provided with insulation or an insulator sleeve surrounding the conductors. This insulation is also typically flexible and, in some applications, serves to protect the conductors from external mechanical, thermal, and / or chemical influences.

[0003] Continuous adhesion between the interior of the insulator sleeve and the exterior of the conductor is disadvantageous if the conductor must be adapted to the spatial conditions of the connected electrical module during assembly. For example, height differences between individual connection points on an electrical module can be bridged by bending the conductor together with the insulator sleeve. Especially with small bend radii, material stresses can occur when the insulator sleeve and conductor adhere to each other, potentially damaging the conductor and / or the insulator sleeve. Summary of the Invention

[0004] The present invention is therefore based on the object of improving the functionality and operational safety of the above-mentioned device.

[0005] This object is achieved by a device for attaching an insulator sleeve for accommodating an electrical conductor to the electrical conductor, wherein the device comprises an insulator sleeve and a mounting sleeve, wherein the end of the insulator sleeve can be accommodated in a receptacle opening of the mounting sleeve, and wherein at least one retaining pin is provided which penetrates the insulator sleeve and fixes the mounting sleeve to the insulator sleeve in a non-displaceable manner along the length direction of the insulator sleeve.

[0006] The advantage achieved by the above device is that a positive-locking and preferably releasable connection is formed between the insulator sleeve and the mounting sleeve, and thus a non-adherent insulator sleeve can be easily attached to the electrical conductor. In particular, at least one retaining pin is used to establish this positive-locking, preferably releasable connection between the insulator sleeve and the mounting sleeve.

[0007] The invention can be further developed by means of the following embodiments, each of which is advantageous in itself and can be combined with one another in any desired manner.

[0008] The insulator sleeve is preferably configured to be used for an electrical conductor of a predetermined size or cross-sectional geometry. In this configuration, electrical conductors of different sizes or cross-sectional geometries should not be used together with such an insulator sleeve.

[0009] To create a positively locking, preferably releasable, connection between the electrical conductor and the mounting sleeve, at least one retaining pin can penetrate the electrical conductor in addition to the insulator sleeve. In this configuration, the at least one retaining pin is located at a position within the insulator sleeve where the conductor of a predetermined size or cross-sectional geometry is located. Alternatively, the electrical conductor can be displaceably attached to the insulator sleeve without being penetrated by the retaining pin.

[0010] By configuring the insulator sleeve for an electrical conductor of a predetermined size or cross-sectional geometry, at least two, preferably parallel, retaining pins can be provided at a distance perpendicular to the length direction that is greater than the width of the electrical conductor corresponding to the predetermined size or cross-sectional geometry, so that the electrical conductor can pass between the retaining pins without being penetrated by the retaining pins. If desired, in this embodiment, a positively locking, preferably releasable, connection between the electrical conductor and the mounting sleeve can be formed by other means, as described below.

[0011] According to one embodiment of the present invention, the insulator sleeve may have at least one through-opening extending perpendicular to the length direction for inserting or passing at least one retaining pin. The inner diameter and / or inner contour of the at least one through-opening corresponds to the outer diameter and / or outer contour of the at least one retaining pin.

[0012] Preferably, the insulator sleeve is constructed as a tubular insulating jacket and has at least one pair of aligned through openings extending perpendicularly to the length direction, the through openings in the pair being arranged on the outer surface of the insulating jacket opposite to each other relative to the length direction of the insulator sleeve constructed as an insulating jacket.

[0013] Alternatively, the insulator sleeve can have a plurality of through openings, which are arranged in pairs overlapping in a plug-in direction perpendicular to the length direction of the insulator sleeve. In this case, a corresponding number of retaining pins can be provided.

[0014] The at least one through opening allows a clearly definable and repeatable positioning of the insulator sleeve relative to the mounting sleeve. This simplifies the assembly of the insulator sleeve and the mounting sleeve.

[0015] In another embodiment, the mounting sheath can be constructed in multiple parts, preferably in two parts. To this end, the mounting sheath can be composed of a first shell and a second shell, which can be inserted together with the first shell in an insertion direction perpendicular to the length direction. The shells can optionally be constructed together and together form the receptacle opening when assembled.

[0016] The two-part embodiment allows, in a first assembly step, to provide the insulator sleeve and / or the electrical conductor in the first housing in the insertion direction, and subsequently, in a second assembly step, to push the second housing onto the first housing in the insertion direction. Thus, the assembly steps can be automated, for example, in a pick-and-place process.

[0017] According to another embodiment, the at least one retaining pin can be part of the mounting sleeve, thereby reducing the number of required individual components. In particular, the retaining pin can protrude from a surface of the mounting sleeve that faces inward in the plugging direction and extend into the receptacle opening. The at least one retaining pin can be designed as a straight, in particular cylindrical, dome-shaped, mandrel-shaped, cubical, or prismatic projection.

[0018] In this embodiment, the at least one retaining pin can, for example, penetrate a pair of aligned through-openings of the insulator sleeve and form a positive-locking connection between the insulator sleeve and the mounting sleeve. Preferably, the insulator sleeve is made as a soft component, such as a silicone insulating tube, and the mounting sleeve is made of a material having a yield limit under mechanical stress that is higher than the tensile strength of the soft component. Thus, the load capacity of the positive-locking connection between the insulator sleeve and the mounting sleeve is clearly defined, since the material of the insulator sleeve tears before the at least one retaining pin of the mounting sleeve is significantly deformed.

[0019] In a two-part embodiment of the mounting sleeve, the at least one retaining pin may be part of the first housing, whereby it acts as a positioning aid insofar as the at least one retaining pin determines where the at least one through opening of the insulator sleeve is to be placed.

[0020] If a plurality of retaining pins are provided on the first housing, their shapes can differ from one another in order to produce a geometric coding which also prevents incorrect positioning of the insulating sleeve.

[0021] Optionally, at least one retaining pin can be part of the first housing, and the pin end of the respective retaining pin facing away from the first housing can visibly penetrate the second housing. In particular, the at least one retaining pin can protrude from the first housing in the direction of the second housing, whereby, in the assembled state, the respective pin end penetrates an inspection opening in the second housing and is thus visible on the outer surface of the mounting sleeve. Preferably, the inspection opening of the second housing is aligned with the at least one through-opening of the insulator sleeve.

[0022] This allows for a visual check during and / or after assembly to check whether the insulator sleeve was positioned correctly during assembly. In the event of incorrect positioning, the at least one retaining pin cannot penetrate the through opening in the insulator sleeve, so that the pin end of the at least one retaining pin is covered by the insulator sleeve and is not visible.

[0023] If multiple retaining pins are provided on the first housing, a corresponding number of inspection openings, through which the individual retaining pins penetrate, can be provided on the second housing. The retaining pins and inspection openings can also be arranged alternately on the first and second housings. Furthermore, the retaining pins can have different shapes and, together with the associated inspection openings, form a geometric code that further prevents incorrect positioning of the housings.

[0024] For example, a first housing and an associated second housing may have a plurality of retaining pins and inspection openings that are different in number, position, and shape from another group of associated housings. In this way, a key locking principle can be implemented that prevents housings that do not belong together from being plugged together and installed.

[0025] Alternatively, the at least one retaining pin can be a separate component that penetrates the mounting sleeve and / or the insulator sleeve. The at least one retaining pin can be configured, for example, as a screw, preferably a hand screw, which is screwed into a threaded hole in the mounting sleeve, the first housing, and / or the second housing and thereby penetrates the at least one through-opening of the insulator sleeve.

[0026] In another embodiment, at least one latching device for latching the two housings can be located outside the receptacle opening of the mounting sleeve and outside the insulator sleeve. Thus, the at least one latching device is easily accessible and helps simplify disassembly of the positive-locking connection between the insulator sleeve and the mounting sleeve. Additionally or alternatively, at least one latching element can be located at the outer edge of the end of at least one retaining pin, which can engage the inner edge of a corresponding inspection opening.

[0027] In another alternative embodiment, the first housing and the second housing may be joined together by a connection including a screw connection, an adhesive connection, a welding connection and / or a soldering connection.

[0028] According to another embodiment, the receptacle opening of the mounting sheath can extend in a longitudinal direction and have a rectangular cross-section in a plane perpendicular to the longitudinal direction. In this case, the mounting sheath can be formed into a cuboidal shell with two flat sides and two long sides connecting the flat sides surrounding the receptacle opening, wherein the resulting inner circumference of the receptacle opening is configured to perfectly seal the insulating sleeve surrounding the electrical conductor. This embodiment is advantageous for applications using flat conductors and is particularly suitable for cell connectors for battery modules.

[0029] Alternatively, the receptacle opening of the mounting sleeve may have a square, polygonal, circular or oval cross-section in a plane perpendicular to the length direction and be adapted to suitably shaped insulator sleeves and electrical conductors.

[0030] Optionally, the mounting sleeve may include at least one housing portion of the contact element for attachment to the electrical conductor (e.g., soldered to the end of the electrical conductor). In particular, the housing portion may surround a distal end of the contact element facing away from the electrical conductor for longitudinal fixation. To this end, the housing portion may extend beyond the distal end in the longitudinal direction and rest on at least one surface of the contact element facing the longitudinal direction and on at least one surface of the contact element facing the longitudinal direction.

[0031] The device according to the invention may further comprise an electrical conductor, wherein the insulating sleeve preferably surrounds the electrical conductor along its entire length, and a positively locking, preferably releasable, connection is present between the mounting sleeve and the end of the electrical conductor received in the receptacle opening, acting in the lengthwise direction of the electrical conductor. To this end, the electrical conductor may optionally have at least one recess adapted to complement the at least one retaining pin, the at least one retaining pin at least partially projecting into the recess and thereby securing the mounting sleeve to the electrical conductor against tension acting in the lengthwise direction of the electrical conductor.

[0032] In this way, the insulator sleeve can be fixed to the electrical conductor by the mounting sleeve and at the same time locally restricted relative movements between the insulator sleeve and the electrical conductor can take place unhindered, for example within the scope of mechanical stress equalization movements.

[0033] Optionally, the end of the electrical conductor received in the receptacle opening may include a contact element. The contact element may be welded, soldered, or screwed, for example. In this embodiment, a positive-locking connection may be established between the mounting sleeve and the contact element. For example, the aforementioned longitudinal fixation may be provided between the contact element and the housing portion of the mounting sleeve, thereby securing the mounting sleeve to the electrical conductor without displacement along its length. In particular, this positive-locking connection can be achieved without requiring at least one retaining pin to penetrate the electrical conductor.

[0034] In another embodiment, the insulator sleeve and the mounting sheath together can form contact protection for the electrical conductors and contact elements, preferably contact protection according to IPXXD or other relevant standards. To this end, the outer surfaces of the insulator sleeve and the mounting sheath are configured so that any existing gaps, such as the distance between the inner edge of the inspection opening and the outer edge of the pin end of at least one retaining pin, are less than X mm. This results in protection against the insertion of wires with a diameter greater than X mm, where X is the value required by the relevant standard for contact protection.

[0035] According to another embodiment, the device can include at least one additional insulator sleeve and an additional mounting sleeve for attaching the at least one additional insulator sleeve to the at least one additional electrical conductor. In particular, the at least one additional mounting sleeve can include a receptacle opening with at least one retaining pin for positively lockingly receiving the end of the at least one additional insulator sleeve and / or the end of the at least one additional electrical conductor, so that the at least one additional mounting sleeve can be fixed to the at least one additional insulator sleeve in a non-displaceable manner along the length of the at least one additional insulator sleeve. This is advantageous for applications where multiple electrical conductors must be connected to an electrical module, such as in the interconnection of battery modules.

[0036] Alternatively, in this embodiment, the mounting sleeves can be integrally connected to one another in order to reduce the number of required individual components.The individual mounting sleeves can be constructed according to the advantageous embodiments already described.

[0037] In a particularly advantageous embodiment, the mounting sleeve can be composed of a first plurality of housings forming the mounting sleeve and a second plurality of housings forming the mounting sleeve. Preferably, the first plurality of housings can be latched together with the second plurality of housings in the insertion direction. This embodiment allows all insulator sleeves and / or all electrical conductors to be placed in the first plurality of housings in the insertion direction in a first assembly step, followed by the insertion of the second plurality of housings into the first plurality in the insertion direction in a second assembly step. These assembly steps can thus also be automated, for example, in a pick-and-place process. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] First, refer to Figures 1 to 8 The schematic structure of the device 1 according to the invention is shown according to a first possible embodiment. Figure 9 and 10 A schematic structure of a device 1 according to the invention is described according to another possible embodiment.

[0050] In a first possible embodiment, the device 1 according to the present invention may comprise a mounting sheath 2 and an insulator sleeve 4. The insulator sleeve 4 may house or surround an electrical conductor 6, wherein the device 1 may also comprise the electrical conductor 6. Alternatively, the insulator sleeve 4 may surround the electrical conductor 6 along its entire length.

[0051] like Figure 1 As shown, the device 1 can be used to attach an insulator sleeve 4 to an electrical conductor 6 via a mounting sleeve 2. In particular, the end 8 of the insulator sleeve 4 and / or the end 10 of the electrical conductor 6 can be received in a receptacle opening 12 of the mounting sleeve 2 and fixed in a non-displaceable manner along the length direction 18 of the insulating sleeve.

[0052] According to the embodiment shown, the mounting sheath 2 is constructed in two parts. To this end, the mounting sheath 2 can be composed of a first shell 14 and a second shell 16, which can be inserted together with the first shell 14 in an insertion direction perpendicular to the longitudinal direction.

[0053] The housings 14, 16 can be adapted to latch onto each other and, when assembled, can together form the receptacle opening 12. In particular, there can be at least one latching device 22 for latching the two housings 14, 16 outside the receptacle opening 12 of the mounting sleeve 2 and outside the insulator sleeve 4. Alternatively, the first housing 14 and the second housing 16 can be connected to each other by a connection comprising a threaded connection, an adhesive connection, a welded connection, and / or a soldered connection.

[0054] exist Figure 1 and 5 In the exemplary representation shown, the electrical conductor 6 is configured as a flexible, flat conductor 24 for a battery cell connector 26 of a battery module (not shown). However, the electrical conductor 6 can have any desired geometry, which is preferably predetermined and adapted to the shape of the insulator sleeve 4 and the shape of the receptacle opening 12. Thus, the receptacle opening 12 of the mounting sheath 2 can extend straight in the longitudinal direction 18 and have a rectangular cross-section in a plane perpendicular to the longitudinal direction 18. Alternatively, the receptacle opening 12 of the mounting sheath 2 can have a square, polygonal, circular, or oval cross-section in a plane perpendicular to the longitudinal direction 18 and be configured for correspondingly shaped insulator sleeves 4 and electrical conductors 6.

[0055] like Figure 3 and Figure 4 As shown in the cross-sectional view in FIG, the mounting sheath 2 for forming a rectangular cross section can be composed of a cubic shell 28, the two flat sides 30a, 30b of which and the two long sides 32a, 32b connecting the flat sides 30a, 30b surround the receptacle opening 12. The resulting inner circumference of the receptacle opening 12 can be configured so that the insulator sleeve 4 around the electrical conductor 6 can be perfectly closed.

[0056] like Figure 5 As shown, the electrical conductor 6 can have a contact element 34 at the end 10 accommodated in the receptacle opening 12. The contact element 34 can, for example, be welded, soldered or screwed to a housing part 36 of the mounting sleeve 2 and can be accommodated therein. In particular, the housing part 36 can surround a distal end 38 of the contact element 34 facing away from the electrical conductor 6 and form a longitudinal fixation 40. To this end, the housing part 36 can extend beyond the distal end 38 in the longitudinal direction 18 and rest on at least one surface 42 of the contact element 34 facing the longitudinal direction 18 as well as on at least one surface 44 facing the longitudinal direction 18. This results in a positively locking, preferably releasable, connection between the electrical conductor 6 and the mounting sleeve 2. This is in Figure 6 Shown in.

[0057] like Figure 1 and 2As shown, at least one retaining pin 7 is provided in the receptacle opening 12, which pin penetrates the insulator sleeve 4 and thus fixes the mounting sleeve 2 non-displaceably on the insulator sleeve 4 in the longitudinal direction 18. Depending on the application, one retaining pin 7 may be sufficient, as long as at least one retaining pin 7 forms a positively locking, preferably releasable, connection between the insulator sleeve 4 and the mounting sleeve 2.

[0058] As an alternative or in addition to the longitudinal fixation 40 already described, at least one retaining pin 7 can also penetrate the electrical conductor 6 in order to form a positively locking, preferably releasable, connection between the electrical conductor 6 and the mounting sheath 2. To this end, the electrical conductor 6 can have at least one recess 46 which is complementary to the at least one retaining pin 7 and into which the at least one retaining pin 7 at least partially projects. Figure 9 and 10 is shown as an example.

[0059] exist Figure 1 and 2 In the exemplary embodiment shown, in particular, two parallel retaining pins 7a, 7b are arranged at a distance from each other perpendicular to the longitudinal direction 18, the distance 48 between the two retaining pins 7a, 7b being greater than the width 50 of the electrical conductor 6, so that the electrical conductor 6 can pass between the two retaining pins 7a, 7b without being penetrated by the two retaining pins 7a, 7b. Figure 3 is shown in a cross-sectional view.

[0060] like Figure 3 As further shown, at least one retaining pin 7 can be part of the mounting sleeve 2 and protrude from a surface 52 of the mounting sleeve 2 facing inwardly toward the receptacle opening 12 and into the receptacle opening 12. In the exemplary embodiment shown, the retaining pins 7a, 7b are configured as straight cylindrical projections 54a, 54b, which protrude from the first housing 14 into the receptacle opening 12, whereby a pin end 56a, 56b of the respective retaining pin 7a, 7b, facing away from the first housing 14, penetrates a respective inspection opening 58a, 58b in the second housing 16. Preferably, in the assembled state of the housings 14, 16, the respective pin end 56a, 56b is visible on an outer surface 60 of the mounting sleeve 2.

[0061] In addition or as an alternative to the at least one latching device 22 , at least one latching element 64 may be located on the outer edge 62 of the pin end 56 of at least one retaining pin 7 , which may latch with the inner edge 66 of the inspection opening 58 .

[0062] In alternative embodiments (not shown), at least one retaining pin can also be configured as a dome-shaped, mandrel-shaped, cubical, or prismatic projection. If multiple retaining pins are provided, their shapes can differ from one another, thereby creating a geometric coding. Furthermore, a set of first housings 14 and associated second housings 16 can, for example, have multiple retaining pins 7 and inspection openings 58, the number, position, and shape of which differ from another set of associated housings, based on the key locking principle.

[0063] like Figure 5 As shown, the insulator sleeve 4 may have at least one through opening 68 for inserting or passing at least one retaining pin 7. Preferably, the inner diameter and / or inner contour of the at least one through opening 68 corresponds to the outer diameter and / or outer contour of the at least one retaining pin 7.

[0064] In the exemplary embodiment shown, the insulating sleeve 4 is configured as a tubular insulating jacket 70 and has two pairs 72 a, 72 b of aligned through-openings 68 at the end 8 received in the receptacle opening 12. The through-openings 68 of each pair 72 a, 72 b are arranged opposite one another on the outer surface 74 of the insulating jacket 70 relative to the longitudinal direction 18. The insulating sleeve can of course have a plurality of through-openings 68 arranged in pairs in an overlapping arrangement in the plug-in direction 21 perpendicular to the longitudinal direction of the insulating sleeve 4. Thus, a retaining pin 7 can be provided for each pair of through-openings 68.

[0065] like Figure 7 As shown, the insulating sleeve 4 together with the mounting sheath 2 can form a contact protection 76 for the electrical conductor 6 and the contact element 34, in particular a protection against the insertion of an electric wire (not shown) having a diameter greater than X mm. To this end, the outer surfaces 60, 74 of the insulating sleeve 4 and the mounting sheath 2 can be configured so that any gaps 80 that exist, for example the distance between the inner edge 66 of the inspection opening 58 and the outer edge 62 of the pin end 56 of the at least one retaining pin 7, are less than X mm, where X corresponds to the value required by the standard.

[0066] Figure 9 and 10 A further embodiment of the device 1 according to the invention is shown, which comprises at least one further insulator sleeve 4' and a further mounting sleeve 2' for attaching the at least one further insulator sleeve 4' to at least one further electrical conductor 6'. In particular, the at least one further mounting sleeve 2' can have a receptacle opening 12' with at least one retaining pin 7' for positively lockingly receiving an end piece 8' of the at least one further insulator sleeve 4' and / or an end piece 10' of the at least one further electrical conductor 6'.

[0067] like Figure 9 and 10As further shown, the mounting sleeve 2, 2' can be constructed from a first plurality of shells 82' forming the mounting sleeve 2, 2' and a second plurality of shells 84' forming the mounting sleeve 2, 2'. Preferably, the first plurality of shells 82' can be latched together with the second plurality of shells 84' in the insertion direction 20. Optionally, the plurality of shells 82', 84' can be configured such that the receptacle openings 12, 12' are arranged coplanar.
