Abstract

An assembly. The assembly includes a first element and a second element, wherein the elements are fastened to one another in such a way that they together enclose an assembly interior, and wherein an electrically conductive cable protrudes into the assembly interior through a cable passage formed between the elements. For forming a particle seal assigned to the cable passage, at least one of the elements has at least one projection, which projects in the direction of the other element and presses the cable against the other element.

Claims (21)

1 . An assembly, comprising:

a first element and a second element fastened to one another in such a way that they together enclose an assembly interior, wherein an electrically conductive cable protrudes into the assembly interior through a cable passage formed between the first and second elements, wherein, for forming a particle seal assigned to the cable passage, at least one element of the first and second elements has at least one projection which projects in a direction of the other element of the first and second elements and presses the cable against the other element, wherein:

the first element is a printed circuit board,

the second element is a support element supporting the printed circuit board, and

the support element has the projection, the projection is made of a first material, a base body of the support element is made of a second material, and a modulus of elasticity of the first material is less than a modulus of elasticity of the second material.

2 . The assembly according to claim 1 , wherein the cable is a ribbon cable.

3 . The assembly according to claim 1 , wherein the cable passage is bounded by a passage surface of the first element and a passage surface of the second element.

4 . The assembly according to claim 3 , wherein the projection is arranged on the passage surface of the element and presses the cable against the passage surface of the other element.

5 . The assembly according to claim 3 , wherein the projection is arranged on a surface of the element adjacent to the passage surface of the element and presses the cable against a surface of the other element adjacent to the passage surface of the other element.

6 . The assembly according to claim 1 , wherein the projection is elastically deformable.

7 . The assembly according to claim 1 , wherein the particle seal is formed in such a way that it seals the assembly interior at least with respect to particles that are larger than a smallest distance between adjacent conductor paths of the printed circuit board.

8 . The assembly according to claim 1 , wherein the projection is an electrical component arranged on the printed circuit board.

9 . The assembly according to claim 1 , wherein the support element has the projection, and the projection and a base body of the support element are made of the same material.

10 . A drive device, comprising:

an electric machine arranged in a housing, which has a rotatably mounted rotor; and

an assembly including:

a first element and a second element fastened to one another in such a way that they together enclose an assembly interior, wherein an electrically conductive cable protrudes into the assembly interior through a cable passage formed between the first and second elements, wherein, for forming a particle seal assigned to the cable passage, at least one element of the first and second elements has at least one projection which projects in a direction of the other element of the first and second elements and presses the cable against the other element, wherein:

the first element is a printed circuit board,

the second element is a support element supporting the printed circuit board, and

the support element has the projection, the projection is made of a first material, a base body of the support element is made of a second material, and a modulus of elasticity of the first material is less than a modulus of elasticity of the second material.

11 . The drive device according to claim 10 , wherein the assembly has a sensor element and is formed to detect a rotational position of the rotor using the sensor element.
