Description
Technical Field
The invention relates to a clamping assembly and a method for accommodating electrical components.
Background
It is known to mechanically screw the contact to a component for holding the contact by means of so-called screw lugs. However, such mechanical connection of the contacts is error-prone and also complicated, since, for example, additional suitable tools must always be provided. A simpler solution for mechanically connecting the contacts consists in connecting the contacts to the component to be fixed by means of a clip connection or a snap-on connection. The existing solutions provide for a simple anti-loss mechanism.
Additional factors must be taken into account in the connection of the clamps in connection with the contactor, such as sufficient mechanical support in the presence of vibrations or shocks and the possibility of tolerance compensation in the X-direction and the Y-direction.
Disclosure of Invention
The object of the invention is therefore to provide a clamping arrangement and a method for receiving electrical components using a device of as simple a construction as possible.
This object is achieved by the subject matter of the independent claims. Advantageous developments of the invention are described in the dependent claims, the description and the drawings.
The disclosure is based on the recognition that the above task can be solved by a clamping assembly and a method, wherein a spring element is arranged between a first lateral element and a second lateral element of the clamping assembly, wherein the spring element is designed to spring back in the direction of the receiving space and to abut against the electrical component when the electrical component reaches a final position in which the electrical component is fully received by the clamping assembly, thereby exerting a defined contact force on the electrical component to hold the electrical component in the clamping assembly. The clamping assembly also has a latching element to lock a portion of the electrical component with the latching element when the electrical component is in the final position. In addition, in the present invention, the two side members and the spring member are formed of a V0 plastic material. This results in a workable geometry of the spring element. The V0 plastic material is characterized in that it can contain additives having a flame-retardant effect and a glass fiber component. This achieves a high elongation at break of the two lateral elements and the spring element. In particular, the current geometry of the spring element or of the two lateral elements is selected accordingly, on account of the high elongation at break of the plastic. In particular, the theme of electric vehicles and high voltage applications in the automotive industry requires the use of V0 plastic materials.
According to one aspect of the invention, the disclosure relates to a clamping assembly for receiving an electrical component, having at least one first lateral part and at least one second lateral part, which are connected to one another by means of a base element in such a way that they form an accommodation space for receiving the electrical component, which is open at least in sections facing upwards and opposite to an insertion direction of the electrical component into the clamping assembly, wherein a spring element is arranged between the first lateral part and the second lateral part, wherein the spring element has a base element and a head element, wherein the base element is arranged between the first lateral part and the second lateral part, and wherein the head element of the spring element is designed to move away from the accommodation space when the electrical component is inserted into the accommodation space in the insertion direction, and wherein the head element of the spring element is also designed to spring back in the direction of the accommodation space and to abut against the electrical component when the electrical component reaches a final position in which the clamping assembly is fully accommodated by the clamping assembly, so that a defined contact force is exerted on the electrical component for holding the electrical component. At least the second lateral part has at least one latching element, so that a part of the electrical component can be latched with the latching element when the electrical component is in the final position, wherein the two lateral parts and the spring part are formed from a V0 plastic material.
The clamping assembly according to the invention achieves the following advantages:
incorrect screwing of the electrical components is avoided, which usually entails additional costs in production, extra work and increased cycle times. Furthermore, automatic supply of electrical components such as contactors can also be achieved. The invention also allows to provide mechanical protection against mechanical loads such as shocks and vibrations in the X-direction and the Y-direction of the electrical component. Furthermore, tolerance compensation in the X-direction and the Y-direction of the electrical component can be achieved. In addition to the accommodation of small tolerances in the Z direction of the electrical components, the invention also allows a loss prevention during the production process to be achieved in a simple manner.
In one embodiment, a portion of the base element of the spring member is used to connect the first and second side members. The advantage is thereby obtained that the clamping assembly has a mechanical durability with respect to external influences.
In one embodiment, the base element of the spring element has a substantially bulging bend pointing outwards away from the receiving space. The advantage is thereby obtained that the spring element is designed in particular to be stretchable, and that, depending on the design of the electrical component, the holding force acting on the electrical component within the clamping assembly can be flexibly adjusted or adapted and can be produced inexpensively, for example in an injection molding machine, without the use of sliders.
In one embodiment, the size and shape of the curved portion of the base element of the spring element can be adjusted according to the contact force to be adjusted that can be exerted on the electrical component. The advantage is thereby obtained that the clamping assembly can be simply and flexibly adapted to the electrical component to be held.
In one embodiment, the head element of the spring element has a retaining portion which is elongated from the base element in order to provide as large a contact or bearing surface as possible for applying a contact force to the side of the electrical component to be contacted. The advantage is thereby obtained that the electrical components to be held are well protected against loads from external effects, such as vibrations and shocks.
In one embodiment, the latching element has a latching projection and is arranged between two spring elements. The advantage is thereby obtained that the clamping assembly particularly securely fixes the electrical component to be accommodated.
In one embodiment, a latching hook or catch hook is formed on the head end of the second lateral element. The advantage of mechanical protection and fixation of the electrical components is thereby obtained.
In one embodiment, the base plate has at least one opening and/or at least one indentation. Hereby the advantage is obtained that air gaps and creepage distances are avoided when external loads act on the clamping assembly and thus on the electrical component to be held.
In one embodiment, the electrical component is designed as a relay or contactor.
According to a second aspect of the invention, the present disclosure is directed to a method of automatically mounting an electrical component with a clamping assembly. In a first step, the clamping assembly is prepared to the mounting position. In a second step, the electrical component is picked up by the holding device. In a third step, the electrical component is inserted into the clamping assembly by moving the clamping device into the receiving space of the clamping assembly in the insertion direction, wherein, when the electrical component is inserted into the receiving space in the insertion direction, the head element of the spring element is moved away from the receiving space and springs back in the direction of the receiving space and abuts against the electrical component when the electrical component reaches its final position in which the clamping assembly is fully received, so that a defined contact force is exerted on the electrical component to hold the electrical component within the clamping assembly. In a fourth step, the latching element of at least the second lateral part is locked with a part of the electrical component when the electrical component is in the final position. The use of templates and auxiliary devices can be dispensed with in particular.

FIG. 1 illustrates a clamping assembly for automated installation of electrical components in one embodiment;

Detailed Description
The figures are only schematic representations and are only used to explain the present invention. Identical or functionally identical components are provided with the same reference symbols throughout the drawings.
Fig. 1 shows a clamping arrangement 1 for receiving an electrical component, having a first lateral part 2,2a and a second lateral part 2,2b, which are connected to each other by means of a base element 6 in such a way that they form a receiving space 10 for receiving an electrical component 20, which is open towards the top and at least partially opposite to an insertion direction 21 of the electrical component 20 into the clamping arrangement 1. The electrical component 20 can preferably be designed here as a relay or a contactor, but is not limited to this function.
The spring element 3 is arranged between the first lateral part 2,2a and the second lateral part 2,2b, wherein the spring element 3 has a base element 3a and a head element 3b. The bottom element 3 is arranged between the first 2,2a and the second 2,2b side piece. The head element 3b of the spring member 3 is designed to move away from the accommodation space 10 when the electrical component 20 is inserted into the accommodation space 10 in the insertion direction 21. The head element 3b of the spring element 3 is also designed to spring back in the direction of the receiving space 10 and to abut against the electrical component 20 when the electrical component 20 reaches a final position in which the electrical component 20 is fully received by the clamping assembly 1. In this way, a prescribed contact force is applied to the electrical component 20 to hold the electrical component 20.
The second lateral part 2,2b has a latching element 4, so that a part of the electrical component 20 can be latched with the latching element 4 when the electrical component 20 is in the final position.
The two lateral parts 2,2a,2b and the spring part 3 are formed from a V0 plastic material. This means that the material has a proportion of flame retardant additive. This has several advantages: on the one hand, this makes the clamping assembly material more difficult to ignite. Furthermore, not all elements of the clamping assembly must have the same degree of robustness, which brings structural advantages in terms of lighter weight and cheaper manufacture of the clamping assembly.
Fig. 1 also shows that the clamping assembly 1 has a portion 3e of the base element 3a of the spring element 3. Which is used to connect the first side member 2,2a and the second side member 2, 2b. As shown in fig. 1 to 3, the side piece 2a can be designed as a relatively high stop in the X/Y direction of the clamping assembly 1 and also has adjustable ribs (not shown) in order to be able to withstand or absorb the high mechanical loads acting on the clamping assembly 1.
In the embodiment shown in fig. 1 to 3, the base element 3a of the spring element 3 has a substantially bulging bend 3f pointing outwards away from the receiving space 10.
The size and shape of the bent portion 3f of the base element 3a of the spring element 3 can be adjusted in this case depending on the contact force to be adjusted which can be applied to the electrical component 20. In this way, the contact force to be exerted on the electrical component 20 to be accommodated can be flexibly set in order to secure it in the clamping assembly 1.
Fig. 1 also shows that the head element 3b of the spring element 3 has a retaining portion 3c which is elongated from the base element 3 a. In this way, as large a contact or bearing surface as possible can be provided for applying a contact force to the side surface 2a of the electrical component 20 to be contacted. Tolerances in the X/Y direction of the clamping assembly 1 can advantageously be compensated for by the holding section 3c (which is embodied as a so-called stripper spring) without the additional use of a slide in the injection molding device.
Fig. 1 to 3 show that the latching element 4 has a latching projection 4a and is arranged between two spring elements 3.
Fig. 1 to 3 also show that a latch hook or latch hook is formed at the head end 2c of the second side part 2,2b, which in the embodiment shown has a downward or inclined shape, for example at the head end 2c of the second side part 2, 2b. These fixing means, such as the latching projections 4a and the latching hooks, allow the electrical component 20 accommodated in the clamping assembly 1 to be reliably fixed and positioned.
As can be seen in fig. 2 and 3, the bottom plate 6 has an opening 7 and a notch 8. They can also be designed as adjustable ribs and help to avoid air gaps and extend the creepage distance.
Fig. 3 also shows the mounted state in which the electrical component 20 is pushed into the clamping assembly 1.
Fig. 4 schematically illustrates a method 100 for automatically mounting an electrical component 20 using the clamping assembly 1. In a first step 110, the clamping assembly 1 is prepared into the installation position. In a second step 120, the electrical component 20 is picked up by a clamping device (not shown in fig. 1-3). In a third step 130, the electronic component 20 is inserted into the clamping assembly 1 by moving the clamping device in the insertion direction 21 into the receiving space 10 of the clamping assembly 1, wherein the head element 3b of the spring element 3 is moved away from the receiving space 10 when the electrical component 20 is inserted into the receiving space 10 in the insertion direction 21, and the head element 3b of the spring element 3 springs back in the direction of the receiving space 10 and abuts against the electrical component 20 when the electrical component 20 reaches a final position in which the electrical component 20 is fully received by the clamping assembly 1, so that a defined contact force is exerted on the electrical component 20 to hold the electrical component 20 in the clamping assembly 1. In a fourth step 140, at least the latching element 4 of the second lateral part 2,2b is locked with a part of the electrical component 20 when the electrical component 20 is in the final position.
