Summary of the Invention

Problems to be Solved by the Invention

[0003] The object of the present invention is to provide an alternative to ultrasonic welding a wire harness to a battery cell connector plate.

Means for Solving the Problems

[0004] The object of the present invention is achieved by electrical sensor contact means for an electrical cell connector plate of a battery, electrical cell connector plate contact terminals for making electrical contact with the electrical cell connector plate, an electrical cell connector plate of the battery, and an electrical entity of a vehicle, in particular a vehicle having an electric traction motor, in particular an assembled electrical cable or battery. Advantageous developments, additional mechanisms, and / or advantages of the present invention can be gathered from the dependent claims and the following description.

[0005] The sensor contact means according to the present invention is designed such that the actual complete sensor contact means is composed of only two parts and is simply insertable into each other, and is formed as a sensor contact means including a cell connector plate contact terminal for an electric cable and a cell connector terminal of a cell connector plate of a battery that is partially complementary to the cell connector plate contact terminal. Here, of course, the cell connector plate contact terminal or the cell connector terminal can have a housing or the like.

[0006] The cell connector plate contact terminal can be formed as a pin terminal, a tab terminal, or a socket terminal. Accordingly, the cell connector terminal can be formed as a socket terminal, a tab terminal, or a pin terminal. The cell connector plate contact terminal and the cell connector terminal can be formed of the same material, particularly aluminum, and the cable can be a copper cable in some cases. This eliminates the difficult process of welding copper to aluminum.

[0007] The cell connector plate contact terminal can have a contact portion for the cell connector terminal and a connection portion for the cable. Here, the connection portion can be formed particularly as a crimping portion. The wall thickness of the cell connector plate contact terminal can be about 25%, about 30%, about 40%, about 50%, about 60%, about 70%, or about 75% of the wall thickness of the cell connector terminal. In other words, the cell connector plate contact terminal can be relatively soft or flexible compared to the cell connector terminal. In particular, the cell connector plate contact terminal can be formed as a socket-shaped pin terminal, and the cell connector terminal can be formed as a socket terminal.

[0008] The cell connector plate contact terminal may be formed by bending in a single layer and / or may partially have an elongated radial spring. Therefore, in this case, the male terminal, preferably a socket-shaped pin terminal, has the spring characteristics of the sensor contact means, and the cell connector terminal is preferably relatively rigid compared to the cell connector plate contact terminal. The cell connector terminal can be bent from the material layer of the cell connector plate. The cell connector plate contact terminal and / or the cell connector plate can be formed as described below.

[0009] The cell connector plate contact terminal according to the present invention has a contact portion and a connection portion for an electric cable, particularly formed as a crimping portion, and the contact portion and the connection portion extend in the axial direction of the cell connector plate contact terminal. The cell connector plate contact terminal has a contact portion and is formed as a male terminal, and the contact portion is bent circumferentially from the material layer to the cell connector plate contact terminal. Additionally or alternatively, the contact portion of the cell connector plate contact terminal can be at least partially bent circumferentially from the material layer to form an axially elongated radial spring (see also the above). In other words, the corresponding cross-section of the contact portion has the form of a radial spring.

[0010] The elongated radial spring can have a substantially O-shaped slotted cross-section, a U-shaped cross-section, or a V-shaped cross-section. Further, the elongated radial spring can be formed as a leg spring having two spring legs in the radial plane of the cell connector plate contact terminal (the cross-section of the contact portion). The leg spring of the cell connector plate contact terminal, that is, the spring portion that can be made in the radial direction of the cell connector plate contact terminal in the axial direction of the cell connector plate contact terminal, receives torque from the leg (inserted into the cell connector terminal) during angular movement and / or rotational movement from the rest position and relaxes again during relaxation.

[0011] The spring legs of the leg springs can be mechanically connected to each other only through a simple connection (simple connection part, simple connection). In other words, the leg springs do not have a complete coil and can thus be called leaf springs and can also be formed as leaf springs. For example (see below), the two side walls of the contact part as the leg of the leg spring are mechanically connected as a simple connection only through the simple bottom wall of the contact part. In the cross-section (radial plane) of the leg spring, the free leg ends of the spring legs can be bent towards each other.

[0012] The contact part can be substantially formed as a contact box, and its electrical contact surface is formed on the outer periphery of the contact box. Here, the contact box is elastically designed in the radial direction at the cell connector plate contact terminal, that is, the elongated radial spring is formed as a substantially box-shaped radial spring. Further, the contact part can substantially have two side walls connected by a bottom wall and preferably an open upper part. Further, the contact part can preferably have a substantially polygonal cross-section or a substantially rectangular cross-section or a substantially elliptical cross-section with rounded corners. Here, the substantially rectangular cross-section can of course be a square, and the substantially elliptical cross-section can of course be a circle.

[0013] The contact part can have at least one cell connector terminal receptacle on the outside, and the cell connector terminal of the cell connector plate can be received in this cell connector terminal receptacle. The contact part can have two or at least two cell connector terminal receptacles substantially on the opposite sides in the radial direction. Here, the cell connector terminal receptacle can be constituted by a radial elastic spring element, an axial stop, and the outside of the contact part.

[0014] The contact part, contact box, and / or elongated radial spring can have one or at least one radial elastic spring element, or can have two or at least two radial elastic spring elements that are substantially opposite in the radial direction. Each spring element preferably extends axially and protrudes slightly radially from each side wall (about 25% to about 150% of the thickness of the material layer of the cell connector plate contact terminal).

[0015] The contact part, contact box, and / or elongated radial spring can have one or at least one axial stop, or can have two or at least two axial stops that are substantially opposite in the radial direction. Each axial stop preferably extends radially and protrudes radially from each side wall (about 100% to about 300% of the thickness of the material layer of the cell connector plate contact terminal). In this regard, each axial stop itself can be designed to be axially elastic. The radial elasticity of each such axial stop is provided, for example, by providing an elongated radial spring.

[0016] A transition part can be formed axially between the contact part and the connection part. The transition part can here serve to connect the cell connector plate contact terminal to a reel. In an embodiment, the cell connector plate contact terminal is formed without an insulation crimping part. The cell connector plate contact terminal can be part of the sensor contact means according to the present invention.

[0017] The cell connector plate according to the present invention includes a plate-shaped connector body for electrically connecting a plurality of battery cells of a battery, and the plate-shaped connector body has cell connector terminals for electrically contacting the cell connector plate. In this regard, the cell connector terminals can be formed as socket terminals, pin terminals, or tab terminals.

[0018] The cell connector terminal can be electrically connected to the connector body by at least one side or only one side, or by at least two sides or only two sides. Further, the cell connector terminal can be disconnected from the connector body and / or bent from the plane of the connector body. In this case, the cell connector terminal can protrude from the connector body in the form of a split piece, and the split-piece cell connector terminal, of course, does not rise from the connector body but remains preferably integrally connected to the connector body (see below).

[0019] In an embodiment, the cell connector terminal can be formed as a socket terminal having a substantially elliptical or polygonal inner cross-section and / or outer cross-section. The preferred elliptical inner cross-section and / or outer cross-section is preferably a circular inner cross-section and / or outer cross-section in this case. The preferred polygonal inner cross-section and / or outer cross-section is preferably a square or rectangular inner cross-section and / or outer cross-section in this case.

[0020] The cell connector terminal can be preferably formed as a sleeve or roll open at both axial end faces. In this case, the cell connector terminal can be formed such that the cell connector plate contact terminal can be inserted into the sleeve or roll from both end faces, which of course also applies to other embodiments. The cell connector terminal may be provided with slots around it, and the slots preferably extend axially along the full extension of the cell connector terminal. Alternatively, the free peripheral end of the cell connector terminal can be fixed to the connector body, for example, by a welding spot.

[0021] The cell connector terminal can be formed by a single bent tab or by two tabs of the connector body bent towards each other. In this case, the connector body serves the function of the base of the cell connector terminal. The cell connector plate can be easily manufactured by a stamping process, for example, including its cell connector terminal and, in some cases, using a mandrel. Further, the cell connector plate can have a welding area as an electrical contact device for the battery terminal, a measurement recess for the battery terminal, a power contact device, a mechanical bridging area, and, in some cases, a thermal bridging area (bead), etc. The cell connector terminal of the cell connector plate may be part of the sensor contact means according to the present invention.

[0022] The cell connector plate contact terminal or the cell connector plate may be provided as one piece, materially one piece, or integrally formed with the cell connector terminal. The one-piece design is understood to be a design of the cell connector plate contact terminal or the cell connector plate including the cell connector terminal, where the individual parts are fixed to each other in a non-positively and / or positively-locking manner (in a non-positively and / or positively-locking manner, with non-shape and / or shape connections), and can preferably be separated again into the individual parts without damage. In the case of a multi-piece design, non-positively locking connections and / or positively locking connections do not necessarily exist, or the connection is established by a third part.

[0023] Substantially (by adhesion), the design of a component is such that the individual components are fixed to each other so that they are substantially joined (by welding, soldering, adhesive bonding, etc.) and preferably cannot be separated into individual components without damage, understood to be the design of a cell connector plate contact terminal or a cell connector plate including a cell connector terminal. In this case, further bonding can be caused by non-positive block connection and / or positive block connection (not applicable in the case of an integral design).

[0024] The integral design means the design of a cell connector plate including a cell connector plate contact terminal or a cell connector terminal, where there is only a single component and it can only be separated by destruction. The component is manufactured from a single first piece (metal sheet, blank, etc.) and / or from a single first mass (molten metal), which necessarily becomes integral. The integral bonding is done by adhesion and / or sticking. In all embodiments, there may further be coating, deposition, electroplating, etc.

[0025] The cell connector plate contact terminal or the cell connector terminal can be substantially formed as only a completely single layer. Further, the cell connector plate contact terminal or the cell connector terminal does not have to be formed as a power terminal for battery current. That is, the cell connector plate contact terminal and / or the cell connector terminal are formed as voltage taps, especially for sensor applications.

[0026] The electrical connector according to the present invention has at least one cell connector terminal according to the present invention or a cell connector plate according to the present invention and a housing, especially a plastic housing. The electrical plug connection part according to the present invention comprises, where applicable, at least one cell connector terminal according to the present invention and, where applicable, a cell connector plate according to the present invention. The entity according to the present invention comprises at least one component and a cell connector plate contact terminal according to the present invention and / or a cell connector plate according to the present invention.

[0027] Such entities according to the present invention are formed, for example, as electrical components, assembled electrical cables, electrical modules, electrical devices, batteries (accumulators), electrical apparatuses, electrical units, etc. In this regard, the entity can, of course, comprise a connector according to the present invention and / or a plug connection according to the present invention. The (pre-)assembled cable (entity) according to the present invention in this case particularly has an electrical cable (component), and if applicable, a connector housing (component), and a cell connector terminal according to the present invention. In particular, the battery (entity) according to the present invention comprises at least one battery module (component), and if applicable, a battery housing (component), and a cell connector plate according to the present invention.

[0028] Vehicles having an electric traction motor, particularly motor vehicles (road vehicles), furthermore railway vehicles, ships, and / or aircraft are understood to be motor vehicles that can have further non-electric drive devices such as internal combustion engines in addition to the electric traction motor. In other words, a vehicle having an electric traction motor can be understood to mean, for example, a hybrid electric vehicle, an electric vehicle (driven only by an electric motor), a fuel cell vehicle, etc.

[0029] Hereinafter, the present invention will be described in more detail based on exemplary embodiments with reference to the accompanying schematic drawings which are not to scale. Parts, elements, components, units, components, and / or patterns having the same, unique, or similar configurations and / or functions are identified by the same reference signs in the description of the drawings (see below), the description of the reference signs, the claims, and the drawings. Possible alternatives, static and / or kinematic inversions, combinations, etc. that are not described, illustrated, and / or definitive for the exemplary embodiments of the present invention, or their components, patterns, units, structural parts, elements, or parts, can be further gathered from the description of the reference signs and / or the description of the drawings.

[0030] In the case of the present invention, a mechanism (part, element, structural component, unit, component, function, variable, etc.) may be in a positive configuration, i.e., even if it exists, or in a negative configuration, i.e., even if it does not exist. In this specification (description (description of the present invention (see above)), description of the drawings (see below), description of reference signs, claims, drawings), a negative mechanism is not explicitly described as a mechanism when its non-existence is not important according to the present invention. That is, the present invention, which is actually made and not constituted by the prior art, omits the said mechanism.

[0031] The mechanisms in this specification may be used not only in a specified manner and / or method, but also in another manner and / or method (separation, combination, substitution, addition, uniqueness, omission, etc.). In particular, based on reference signs and the mechanisms assigned thereto, or mechanisms and the reference signs assigned thereto, the mechanisms in the claims and / or the specification can be substituted, added, or omitted in the specification, description of reference signs, claims, and / or drawings. Furthermore, thereby, the mechanisms in the claims can be described and / or specified in more detail.

[0032] The mechanisms in this specification can also be interpreted as optional mechanisms (considering the prior art which is initially hardly known). That is, each mechanism can be considered as an optional, arbitrary, or preferable mechanism, i.e., a non-binding mechanism. Therefore, the mechanism can be separated from the exemplary embodiments, optionally including its surroundings, and then the said mechanism can be converted into a generalized inventive concept. The absence of a mechanism (negative mechanism) in the exemplary embodiments indicates that the mechanism is optional with respect to the present invention. Furthermore, in the case of terms of types of mechanisms, the general terms of the mechanism (optionally, further hierarchical classification into subgenera, etc.) can also be implicitly understood, whereby the mechanism can be generalized, for example, considering equivalent effects and / or equivalents.

DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, exemplary forms of embodiments of a modified example of an electrical cell connector plate contact terminal 10 for an electrical cable 40 for electrically contacting an electrical cell connector plate 50 of a battery 0, particularly a traction battery 0 of an electric vehicle (particularly, FIGS. 1 to 4), and exemplary forms of embodiments of a modified example of an electrical cell connector plate 50 having a cell connector terminal 510 (FIGS. 5 and 6) will be referred to to explain the present invention.

[0035] The present invention can generally be used in the electrical field in the case of electrical entities. This exception is in terrestrial power engineering (of course, excluding voltage taps for, for example, sensor applications). Further, the present invention will be described and illustrated in more detail using preferred exemplary embodiments, but the present invention is not limited by the disclosed exemplary embodiments and is of a more fundamental nature. Without departing from the scope of protection of the present invention, other variants can be derived from the exemplary embodiments and / or the above (description of the present invention).

[0036] The drawings show only the physical parts of the subject matter of the present invention necessary for understanding the present invention. Names such as connectors and mating connectors, terminals and mating terminals should be interpreted synonymously, i.e., they may be interchangeable with each other. Hereinafter, the description of the present invention with reference to the drawings refers to the axial direction Ar (one of the options thereof is the insertion direction Sr), the radial direction Rr, and the circumferential direction Ur of the cell connector plate contact terminal 10 and the cell connector terminal 510.

[0037] Figs. 1 to 4 show the cell connector plate contact terminal 10, which has three parts 100, 200, 300 formed integrally with each other and arranged in order in the axial direction Ar, namely the contact part 100, the transition part 200, and the connection part 300. The connection part 300 serves to electrically connect the cable 40, is preferably formed as a wire crimping part, and does not have an insulation crimping part, but may have an insulation crimping part. The transition part 200 between the connection part 300 and the contact part 100 is formed in this case for connecting the cell connector plate contact terminal 10 to a reel.

[0038] The cell connector plate contact terminal 10 formed as the crimp terminal 10 is given an overall substantially socket-like shape by being bent from a single material layer. In this case, it is preferable that the cell connector plate contact terminal 10 is substantially formed in a single layer over substantially the entire surface. That is, there is no surface of the cell connector plate contact terminal 10 that is formed in a two-layer or multi-layer configuration by the constituent material layers, and / or such portions are substantially absent. That is, the cell connector plate contact terminal 10 has a single structure.

[0039] The contact portion 100 serves to electrically contact the cell connector terminal 510. The contact portion 100 has the cell connector plate contact terminal 10 as a male terminal, and the contact portion 100 is formed as a socket-shaped contact box with a hollow interior. The male contact portion 100 or the contact box has a surface that electrically contacts the cell connector terminal 510 on the outer periphery (see FIGS. 4 and 6), and is at least partially formed as the radial springs 102; 110, 130, 120. Preferably, substantially the entire contact portion 100 in the axial direction Ar is formed as the elongated radial springs 102; 110, 130, 120. Another configuration of the cell connector plate contact terminal 10, such as a socket terminal or a tab terminal, can of course be applied.

[0040] The cross-section of the radial springs 102; 110, 130, 120 can be clearly seen in FIG. 2. The radial springs 102; 110, 130, 120 include two spring legs 110, 120 that are elastic with respect to each other in the radial direction Rr. The two spring legs 110, 120 can be pushed together from the rest position or are compressible in the radial direction Rr, and the contact portion 100 can be inserted into the cell connector terminal 510. In the inserted state of the contact portion 100, the spring legs 110, 120 open in the radial direction Rr, and thus the outside of the contact portion 100 is pressed against the inside of the cell connector terminal 510 (see FIG. 6).

[0041] In the illustrated embodiment, the contact portion 110 includes a first side wall 110 on one side (the right side in FIG. 2) and a second side wall 120 on the other side (the left side in FIG. 2) from the bottom wall 130, and the side walls 110, 120 are bent toward each other at the free ends, that is, the upper ends. Such regions of the side walls 110, 120 bent toward each other form the slotted (spring slot 142) ceiling 140 of the contact portion 100. This gives the contact portion 110 a slotted O-shaped cross section. Other cross sections such as elliptical, polygonal, U-shaped, V-shaped, etc. are of course applicable.

[0042] Here, the O-shaped cross section of the contact portion 110 can be formed in particular as follows. The bottom wall 130 and the two side walls 110, 120 each have a straight portion. Each straight portion of the side walls 110, 120 forms a rounded corner region together with the base wall 130, respectively. Similarly, the side walls 110, 120 also have rounded corner regions on the side opposite to the bottom wall 130, and there are short straight portions where the spring slots 42 of the ceiling 140 of the contact portion 100 are formed in between.

[0043] Here, the first side wall 110, the bottom wall 130, and the second side wall 120 form a radial spring 102; 110, 130, 120 in or as the contact portion 110. The spring slot 142 of the upper part 140 that divides the upper part 140 into two parts enables the radial spring 102; 110, 130, 120 to function on the one hand, and on the other hand, it may be dimensioned so that the radial spring 102; 110, 130, 120 is not compressed too much in the radial direction Rr. Instead of the radial spring 102; 110, 130, 120, the contact portion 100 or a part of the contact portion 100 may be formed as a functionally similar leg spring or a functionally similar leaf spring, or the radial spring 102; 110, 130, 120 may be formed as a spring by itself.

[0044] The cell connector terminal receptacle 104 is preferably formed outside the contact portion 100, particularly outside the side walls 110, 120. The cell connector terminal receptacle 104 functions to fix the contact portion 100 to the cell connector terminal 510 or vice versa. For this purpose, the cell connector terminal receptacle 104 preferably has spring - type error elements 114, 124 in the radial direction Rr, preferably at the front part of the contact portion 100, and on the other hand, preferably has spring - type axial stops 115, 125 in the axial direction Ar, possibly at the rear part of the contact portion 100. Here, the cell connector terminal receptacle 104 is formed in the radial direction Rr between the spring elements 114, 124 and the axial stops 115, 125. That is, the receptacle 104 is accessible in the radial direction Rr from the outside of the contact portion 100.

[0045] The spring elements 114, 124 are cut out from or separated from the walls 110, 120, 130 of the contact portion 100 ((die) punching and bending process) and project slightly radially from the walls 110, 120, 130 similar to a lock lance. The axial stops 115, 125 are preferably formed as tabs that project radially from the contact portion 100 at one end. Alternatively, the axial stops 115, 125 may be formed in the same way as the spring elements 114, 124, and / or the spring elements 114, 124 may be formed in the same way as the axial stops 115, 125. The contact portion 110 preferably has two cell connector terminal receptacles 104, 104 on opposite sides of each other in the side walls 110, 120.

[0046] Figures 5 and 6 show the pre-assembled electrical cable 1 in addition to the cell connector plate 50. Here, the pre-assembled cable 1 includes the cell connector plate contact terminal 10 and the cable 40 electrically connected to the cell connector plate contact terminal 10. In this case, the cable 40 is attached to the connection portion 300 by a solid conductor, a sector-pressed or compacted conductor, or a stranded wire, and is preferably crimped to the connection portion 300. Other techniques such as soldering or adhesive bonding for attaching the conductor to the connection portion 300 are, of course, applicable.

[0047] Figures 5 and 6 show the cell connector terminals 510 provided on the connector body 500 of the cell connector plate 50. In particular, the cell connector terminal 510 is formed as a bushing terminal 510 and is preferably formed integrally with the connector body 500. The terminal 510 is separated from the connector body 500 on three sides, rounded or bent from the plane of the connector body 500, and thus the cell connector terminal 510 protrudes from the connector body 500 as a sleeve 510 or a roll 510. As a result, the recess 520, particularly the through recess 500, remains in the connector body 500. Other configurations of the cell connector terminal 510, such as pin or tab terminals, are, of course, applicable.

[0048] The cell connector terminal 510 has a conceptually simple structure here and is composed of a simply rounded and bent smooth material layer. The free end of the tab bent to form the cell connector terminal 510 may be seated on the connector body 500 here, or may be arranged on the cell connector plate 50 with the slot 510 spaced apart from the cell connector plate 50. In the first case, the free end of the cell connector terminal 510 can be fixedly connected to the connector body 500, for example, by welding, soldering, or adhesive bonding.

[0049] Furthermore, FIGS. 5 and 6 show the pre-assembled cable 1 when the cell connector plate contact terminal 10 is inserted into the cell connector terminal 510. When the cell connector plate contact terminal 10 is inserted into the cell connector terminal 510, the radial springs 102; 110, 130, 120 of the contact portion 100 are compressed radially, and at that time, the contact portion 100 slides into the socket-shaped cell connector terminal 510, and the front end portion passes through the entire cell connector plate contact terminal 510. At this point, the spring elements 114, 124 are inserted completely through the terminal 510. The insertion of the cell connector plate contact terminal 10 into the cell connector terminal 510 can be facilitated by the chamfered insertion surface (not shown) of the free end face of the contact portion 100.

[0050] With the cell connector plate contact terminal 10 and the cell connector terminal 510 inserted into each other (see FIG. 6), the cell connector terminal 510 is seated on the cell connector terminals receptacles 104, 104 of the contact portion 100. Here, one end face of the cell connector terminal 510 abuts against the spring elements 114, 124 that protrude radially Rr from the contact portion 100. The end face of the cell connector terminal 510 on the opposite side in the axial direction Ar to this end face abuts here against the axial stops 115, 125 that protrude radially Rr from the contact portion 100.
