Description

Field of the invention

[0001] The present disclosure relates to an electrical assembly having a leaded component. Background and general description of the invention

[0002] Leadframes are frequently used in industrial, mass-produced electrical assemblies that utilize a small number of electronic components, typically with two or more connections. Such a leadframe is initially a strip material, which is then formed or brought into a working condition through various punching, bending, and / or nesting processes.

[0003] There are various options for connecting a lead frame part to a wired electronic component—for example, an electrical resistor, capacitor, or diode. For example, they can be plugged, soldered, or welded, or connected using insulation displacement technology.

[0004] From US Patent No. 4,727,648 A, it is known that a circuit component, such as an electrical unit, can be mounted on a printed circuit board by providing a mounting body to support the unit on the board; and by providing conductive means comprising a contact structure with spring fingers to receive a nit terminal, the conductive means including auxiliary clamping means projecting from the body via a body slot, the contact structure and auxiliary clamping means defining a bridge portion with tab means in the body slot to anchor the body. The luminous unit may extend at either end of the housing.

[0005] DE 20 2011 001 820 U1 discloses a protective device for the control electronics of a motor vehicle component. It comprises a thermal protection element arranged between the control electronics and a lead frame, which is triggered when the temperature in the control electronics rises above a temperature threshold. Motor vehicle components are understood to mean, in particular, a radiator fan drive with an electronically controlled DC motor for cooling the cooling water of a motor vehicle.

[0006] Lead frames with dielectric housings fused thereto are known from US Patent No. 4,600,971 A. The electrical lead frames are stamped from a metal strip, each of the lead frames including spaced-apart metal strips extending between support elements. Protrusions extend outwardly from the metal strips. A dielectric housing is fused to each of the lead frames and includes recesses in a surface exposing corresponding protrusions and holes extending through the housing and communicating with the corresponding protrusions, so that the electrical leads of electronic components and electrical wires can be inserted into the holes in electrical engagement with the protrusions and secured therein by the protrusions.

[0007] What the above-mentioned connection techniques have in common is that the wire contacts of the wired components are heated, cut, squeezed or otherwise influenced so that they undergo a mechanical change.

[0008] In order to further reduce costs in this cost-sensitive mass production sector, creative ideas are required, as the sector is subject to constant change and development.

[0009] Against this background, the present invention aims to provide electrical assemblies that can be manufactured even more cost-effectively. In particular, the goal of the development is to be able to use even more cost-effective electrical or electronic components that may not be contactable using the conventional connection technologies mentioned above.

[0010] The present invention is also capable of fulfilling the partial aspect of providing designs that are usable and capable of being populated, particularly in very narrow designs. Finally, the present invention aims to further reduce the production costs of electronic components in a cost-sensitive environment while simultaneously increasing the durability of the product.

[0011] One way to further save costs would be to use wire contacts from wired components that are no longer made of solid copper. There are cheaper components with coated wire contacts. Instead of pure, high-quality copper, they use steel with a copper and tin coating, for example. However, insulation displacement technology cannot be used with such components, as the copper coating, with its tin underlayer, is cut, and corrosion can occur unhindered when exposed to moisture on the steel. The same applies to sharp-edged crimping or welding.

[0012] The problem is solved by the subject matter of the independent patent claims. Dependent claims fulfill further aspects of the present problem.

[0013] An electrical assembly according to the invention comprises a wired electrical component with at least two wire contacts. Such a wired electrical component is known in a wide variety of variations. For example, resistors, capacitors, diodes, or even transistors and microprocessors have been manufactured and sold for decades with so-called "pins," in which the wire contacts can be easily plugged onto printed circuit boards, for example, or soldered or welded to contacts. Due to the cost-sensitive approach in this mass market, it may no longer be possible to use newly manufactured wired electrical components for welding or crimping without damaging the protective layer on the wire contact.

[0014] The electrical assembly according to the invention therefore comprises a stamped grid part, which is typically made of metal and serves to establish an electrical connection between the at least two wire contacts of the wired component and other functional elements of the assembly. The stamped grid part is thus made of a metal material, for example, steel or a ferrous metal material, which is usually used due to costs. In other words, the wired electrical component is contacted to the stamped grid part, so that the electrical component can be connected to other functional elements or electrical connections.

[0015] The lead frame part has a base element and contact tabs arranged thereon. The contact tabs are configured to establish the electrical connection with the at least two wire contacts of the wired component. The contact tabs are arranged on the base element such that they form at least a first and a second receiving area. The respective receiving area is formed in particular between a portion of the contact tabs. In other words, a portion of the contact tabs is grouped around the first receiving area, and another portion of the contact tabs is grouped around the second receiving area.

[0016] For example, the contact tongues on the base element can be spring-loaded, i.e., if the contact tongues are integrally stamped with the base element, particularly from metal material, the sheet metal will have a slightly springy effect. However, this is only optional. The wire can press against the contact tongues solely through its inherent stability and the resulting spring action, and thus be held in the contact area. The wire contact therefore preferably lies springily in a snake-like manner in the gate structure or in the receiving area. The clamping of the wired component in the receiving area is then caused by the wire contact against the contact tongues of the contact area.

[0017] The receiving areas are designed so that at least one of the wire contacts of the wired component can be inserted into the receiving area and held in place by the contact tabs. For example, the wire contact is positioned between the contact tabs or around the contact tabs so that the wired electrical component is held as a whole by the contact tabs.

[0018] In particular, the contact tongues hold the wire contact in the receiving area by applying a clamping force to the wire contact. For example, the contact tongues clamp the wire contact, or a portion of the wire contact, or the portion of the wire contact that is arranged in the receiving area, in the receiving area.

[0019] Preferably, at least one of the contact tongues has a locking lug, so that, in particular, the wire contact is held in the receiving area by the locking lug. The locking lug can be arranged such that the wire contact snaps over the locking lug when the wired electrical component is inserted into the receiving area, and the wire contact is held in its shape by the spring force of the metal material used in the wire contact and does not snap back out of the locking lug on its own. Rather, the locking lug exerts a holding force on the wire contact, so that the wire contact remains in the receiving position.

[0020] The wire contact of the wired component therefore preferably has a rigidity, wherein a locking of the wire contact in the receiving area can be achieved when the wire contact is brought into a locked position past the locking lug against the rigidity of the wire contact.

[0021] If the wire contacts of the wired component have a rigidity, the wire contact can be clamped between the contact tongues if the wire contact is brought into a clamping position between the contact tongues against its rigidity.

[0022] The contact tabs of the stamped grid part, for example, are bent away from the base element. In particular, the contact tabs are arranged perpendicularly or nearly perpendicularly to the base element, for example, at an angle of 90° + / - 5° to the base element. Any radii required for stamping that do not produce a perfectly straight edge are included in this angular relationship.

[0023] Preferably, a receiving area is formed by the contact tongues surrounding the receiving area. For example, a receiving area is formed by at least three contact tongues arranged around the receiving area.

[0024] The electrical assembly can be designed to be housed in an electrically insulating housing, such as a base terminal. The base element can be connected to the housing. For example, the base element can be overmolded using an injection molding process, creating the housing in one piece around the base element. It is also practical to snap the housing around the electrical assembly.

[0025] In one embodiment, at least one of the wire contacts of the electrical component has a length compensation feature to compensate for different length expansions, for example, due to thermal elongation. Such length compensation can be achieved in a simple form by incorporating an S-shape into the wire contact. Length compensation can also be implemented using a U-shape or a coiled spring.

[0026] The contact tongues can have a curvature on the side facing the wire contact, i.e., the side facing the receiving area. For example, the contact tongues on the side facing the receiving area are round, with a specific radius, for example, whereby the wire contact can also be bent around the curvature of the contact tongues.

[0027] The wire contact of the electrical assembly comprises, in particular, an iron core and a coating applied to the iron core. The coating may comprise tin and / or copper, preferably initially a copper layer on the iron wire, followed by a tin layer.

[0028] The contact tongue can have a contact surface, wherein the contact surface in particular has a radius that corresponds to the radius of the wire contact to be inserted. In other words, the contact surface on the contact tongue is shaped so that the wire contact to be inserted rests against the contact surface with the largest possible surface area, for example, to improve the intensity of the electrical contact.

[0029] The contact tongue can further include an insertion aid so that the wire contact can slide along the insertion aid into the receiving area or be pressed there. By pressing along the insertion aid, the wire contact automatically moves into the installed position, preventing the wire contact from breaking out of the insertion direction.

[0030] In the receiving area, the wire contact presses particularly resiliently against the contact tongues of the lead frame part, so that at the same time a good electrical contact can be made between the wire contact and the contact tongues as well as a resilient mechanical clamping of the wire contact against the contact tongues.

[0031] The assembly in particular has two receiving areas, wherein the receiving areas are arranged on opposite sides to one another with the electrical component in between. Alternatively, in the case of the assembly having two receiving areas, the arrangement can be such that the receiving areas are arranged next to one another. If the two receiving areas are arranged next to one another, for example, one of the two wire contacts is bent by 180°, or both wire contacts are each bent by 90°, although any mixed angles between the two wire contacts are of course also possible. Due to the machine production, bending only one wire contact is preferred, in which case this wire contact is then bent by 180°.

[0032] The wire contact(s) form(s) a straight line with the electrical component before being inserted into the receiving area. This means that the wire contact, together with the electrical component to which the wire contact is attached or arranged, share a straight line, which can be placed centrally through both the wire contact and the electrical component. The straight line thus passes through the wire contacts and the electrical component. After being inserted into the receiving area, the wire contact(s) are bent in a serpentine manner around the aforementioned straight line.

[0033] The contact tongues of a receiving area are preferably arranged alternately on opposite sides of the receiving area. This means that the contact tongues of a receiving area, viewed in the longitudinal direction of the wire contact to be inserted, alternate on each side of the wire contact. Thus, viewed in the direction from the electrical component, there is first a contact tongue on a first side of the wire contact, then, at a specific distance, a contact tongue on the second side of the wire contact, and then again, at a specific distance, a contact tongue on the first side of the wire contact. The distance from one contact tongue to the next can, for example, correspond to the diameter of a contact tongue. The distance between two contact tongues can also be smaller than the diameter of a contact tongue, for example, half the diameter of the contact tongue.In particular, the distance between the contact tongues of a receiving area corresponds to the diameter of the wire contact to be inserted or is slightly smaller than the diameter of the wire contact to be inserted.

[0034] The receiving area has a center, i.e. an imaginary line that passes through the electrical component to be inserted and through the receiving area, with the contact tongues being spaced from the center by less than half the diameter of the wire contact to be inserted. For example, the imaginary center line just does not pass through the contact tongues of a receiving area. Depending on requirements, the contact tongues can be arranged such that the remaining straight area around the center line is thinner than the wire contact of the electrical component to be inserted. In this case, the electrical wire contact to be inserted is bent when pressed into the receiving area, i.e. in particular, it is bent around the contact tongues of the receiving area.

[0035] The assembly can preferably be surrounded by a potting compound.

[0036] The invention also includes an arrangement, in particular a base terminal, which comprises an electrical assembly as described above.

[0037] In the following, the invention is explained in more detail using exemplary embodiments and with reference to the figures, wherein identical and similar elements are partly provided with the same reference numerals and the features of the various exemplary embodiments can be combined with one another. Short name of the figures

[0038] They show: Fig. 1 a first embodiment of the invention, Fig. 2 a second embodiment of the invention, Fig. 3a to 3d an example of inserting a wire contact into a contact tongue, Fig. 4 an embodiment of the invention in side view, Fig. 5 shows a further embodiment of the invention, Fig. 6 the embodiment of the Fig. 5 in a plan view, Fig. 7a and Fig. 7b further examples of the design of the contact tongues. Detailed description of the embodiments

[0039] Referring to Fig. Figure 1 shows a first embodiment of the invention, wherein an electrical component 7 with its wire contacts 6 is inserted into a "slotted guide" and, due to its inherent rigidity, is twisted against the conductive contact tongues 2, 3, 4. The contact tongues or contact pieces 2, 3, 4 enable soft contact of the connecting wire 6 to the leadframe without sharp edges and thus without damaging the wire or the coating on the wire. After assembly, the wire contact 6 lies in a serpentine shape in the receiving area 35.

[0040] In this embodiment, the electrical component 7 has two wire contacts 6, 6a, which are arranged laterally on the electrical component 7. Each wire contact 6, 6a is guided into its own receiving area 35, 35a, so that each wire contact 6, 6a can be held alone in a receiving area. This allows separate electrical contact between the two electrical wire contacts 6, 6a. In this example, the wire contact 6 has an S-bend 5, which can be used for length compensation. A change in the length of the wire contacts 6, 6a also occurs during assembly of the electrical component 7, since the twisting of the electrical contacts 6, 6a in the receiving areas 35, 35a shortens the wire contacts 6, 6a and thus influences the overall length 21 of the electrical component 7.

[0041] The recording area 35 of the example of Fig. 1 has four contact tabs 2, 3, 4, 4a. The first wire contact 6 is clamped by the four contact tabs 2, 3, 4, 4a in such a way that the wire contact no longer protrudes from the receiving area 35 due to the inherent rigidity of the metal material used in the wire contact 6, since the wire contact 6 is held between the contact tabs 2, 3, 4, 4a by means of clamping force. In other words, the wire contact 6 is held by the contact tabs 2, 3, 4, 4a of the wire grid part 50, and the wire contact 6a is held by the contact tabs 2, 3, 4, 4a of the wire grid part 52.

[0042] In Fig. 1 a center line 37 is sketched, where in Fig. 1 the distance between the contact tongues 2, 3, 4, 4a in the receiving area 35 to the center line 37 is smaller than the shown diameter of the wire contact 6. Due to the smaller distance between the contact tongues 2, 3, 4, 4a and the center line 37 compared to the diameter of the wire contact 6, the wire contact 6 is automatically forced to make an evasive movement when inserted into the receiving area 35. Through clever arrangement of the contact tongues 2, 3, 4, 4a, the evasive movement of the wire contact 6 at the contact tongues 2, 3, 4, 4a occurs automatically when the wire contact 6 is pressed into the receiving area 35. For example, the deflection of the wire contact 6, 6a occurs in a plane that runs parallel to the main extension direction of the respective base element 1, 10. In this example, the recording area 35a is arranged mirror-symmetrically to the recording area 35.

[0043] The Fig. 2 shows a further embodiment of the invention, wherein the two receiving areas 35, 35a are arranged on one side of the electrical component 7. In this example, the electrical conductor 6a is bent by 180° in order to be able to be inserted into the receiving field 35a. In this example, no length compensation piece 5 is necessary, since a potential change in the length of the wire contacts 6, 6a in this case has no influence on the tension between the two receiving areas 35, 35a. The electrical contact 6 is held in the receiving area 35 by four contact tongues 2, 3, 4, 4a, for example by applying a clamping force to the wire contact 6. Thus, no soldering, welding, or sharp-edged squeezing of the wire is necessary. Rather, complete electrical contact is achieved through the electrical contact of the wire contact 6 with the contact tongues 2, 3, 4, 4a. The same applies to the second wire contact 6a in the second receiving area 35a.

[0044] The Fig. Figures 3a to 3c show the insertion of a wire contact 6 into a locking position on a contact tongue 4 in a detailed view. A wire contact 6 has a steel core inside, which is encased in a copper layer. The tin layer 13 is arranged on top of the copper layer, providing better electrical contact and rust protection for the iron core. The wire 6 is shown from above in the illustration of Fig. 3a onto a contact surface 15 of the contact tongue 4. For this purpose, the wire contact 6 is first placed onto the insertion bevel 12, ie onto the insertion aid 12, so that the wire contact 6 can no longer exit sideways from the lateral guide of the receiving area 35. Fig. 3b, in contrast, shows the wire contact 6 fully inserted into the locking position in the receiving area 35. The wire contact 6 is held in the locking position by the locking lug 16, so that the wire 6 can no longer exit sideways or upwards from the receiving area 35.

[0045] Fig. 3c shows an alternative embodiment without a locking lug, wherein the contact tongue 4 has a sliding area 18, along which the wire contact 6 can slide into the receiving area 35. With a suitable selection of the angle of the sliding area 18, together with the spacing of one contact tongue from the next contact tongue 2, 3, 4, 4a, and due to the spring force of the wire contact 6, a clamping force is generated in the receiving area 35, which securely holds the wire contact 6 in the clamped position on the receiving area 35, without the additional locking lug 16 possibly being required.

[0046] The Fig. 3d shows the example of Fig. 3b with inserted wire 6 in the receiving area, wherein a second contact tongue 3 is shown, which is arranged opposite the contact tongue 4 in the direction of view of the wire. Fig. 4 shows how the wire 6 is arranged in the receiving area 35 and clamped between the contact tongues 2, 3, 4, 4a.

[0047] Fig. 4 shows a side view of a device according to the invention, into which a wired component 7 with two wire contacts 6, 6a is inserted. The wire contact 6 is clamped by contact tongues 2, 3, 4, 4a on the receiving area 35 in such a way that the wire will not leave the receiving area 35 without external influence. The same applies to the receiving area 35a opposite the receiving area 35, in which the wire contact 6a is clamped. In this design, the wired component can typically be inserted into the assembly from above, which can be advantageous, for example, when the assembly is used in tight spaces and walls or other components are arranged on the sides, so that access is only possible from above.

[0048] Fig. Figure 5 shows an alternative design of the invention, wherein the arrangement corresponds to the basic principle of the previously described idea and allows installation rotated by 90°. In this design, the coiled tension of the wire contact 26, 26a relative to the contact area 35, 35a results from one side - for example, in a top view of the end of the wire contact 22 - downwards and upwards, i.e., the deflection of the wire contact 26, 26a occurs in a plane perpendicular to the main extension direction of the respective base element 1, 10. The wired component 7, with its wire contacts 26, 26a, is inserted from one side between the two housing walls 8, 9. The wire contacts 26, 26a wind around the contact tongues 2, 3, 4 of the respective contact area 35 or 35a. For example, they "snap" into the contact area 35 or 35a. The example of Fig. 5 is designed in such a way that the wired component 7 in the representation of the paper plane of the Fig. 5 is inserted from above.

[0049] In this example, the two contact areas 35 and 35a are mirror-symmetrical. All references and reference symbols for contact area 35 therefore also apply to contact area 35a. Contact areas 35 and 35a are explained using contact area 35 as an example.

[0050] The contact area 35 (and in corresponding application, the contact area 35a) is formed by the contact tongues 2, 3, 4, which surround the contact area 35. The contact tongue 2 has a connection contact carrier 23, which connects the contact tongue 2 to the base element 1. The wire contact 26 rests against a contact head 27 of the contact tongue 2, whereby the wire contact 26, in this example, is pushed over the contact head 27 and bent into the rear grip 28. The contact tongue 3 is not gripped from behind; rather, the wire contact 26 can slide in directly here and rest against the contact head 29. The contact tongue 3 also has the contact base 24, which is connected to the base element 1.

[0051] The wire contact 26 is also pushed over the contact head 31 of the contact tongue 4 and snapped into the rear grip 32, so that the wire contact 26 rests against the contact head 31. The wire contact 26 is thus clamped between the contact heads 27, 29, 31 due to its remaining internal tension and presses against the contact tongues 2, 3, 4, or against the respective contact heads 27, 29, 31.

[0052] If the base element 1 together with the contact tongues 2, 3, 4 is preferably formed in one piece and is further preferably provided as a stamped grid part, the above-mentioned divisions of a contact tongue 2, 3, 4, for example the contact tongue 2, into contact carrier 23, contact head 27 and rear grip 28 are a functional division of the one-piece overall component.

[0053] Fig. 6 shows the training form of the Fig. 5 in a top view. The wire contact 26 is securely held in the receiving area 35 by being braced against the contact heads 27, 29, 31. The same applies to the mirror-symmetrically arranged wire contact 26a in the receiving area 35a. In this straight arrangement, the first wire contact 26 has a length compensation 5, here in the form of an S-shaped bend.

[0054] Referring to Fig. 7a shows a further design of a contact tongue 2, as for example in the embodiment of the Fig. 5 or 6. The wire contact 26 is pressed against the contact head 27 by its inherent tension, which is built up when the wire contact 26 is inserted into the contact area 35, whereby the electrical contact with the contact tongue 2 is established and at the same time the wire contact 26 is held in the receiving area 35. If the wire contact 26 is shown in the Fig. 7 is inserted from above, it will be pushed over the rear grip 28 in order to reach its installation position in the contact area 35.

[0055] Fig. Figure 7b shows a further embodiment of the contact tongue 2, 3, 4 as it can be used in all proposed designs. For example, the embodiment of the Fig. 7b as contact tongue 3 in the embodiment of the Fig. 5 and 6 together with the embodiment of the contact tongues 2 and 4 according to Fig. 7a. The wire contact 26 is pressed against the contact base 24 by the inherent residual stress that arises when the wire contact 26 is inserted into the contact area 35, thereby achieving electrical contact therewith on the one hand and mechanical clamping in the contact area 35 on the other.

[0056] With the device shown here, a wired component can be easily inserted without the need for soldering, welding, or pressing the wire contacts. This allows any coating present on the wire contacts 6, 6a to be protected in a gentle manner. This is particularly advantageous for machine production, i.e., the machine assembly of assemblies with wired components 7. In particular, when inserting the wired component into the receiving areas 35, 35a, the wire contacts 6, 6a simply slide along the sliding surfaces 18 or the locking points 16. The rigidity of the wire contacts 6, 6a, together with the rounding of the contact tongues 2, 3, 4, 4a on the side facing the wire contact 6, 6a, enables this sliding installation of a wired component 7.
