Description

 Functional component housing with a seal

The invention relates to a functional component housing with a seal.

Seals are used between connecting housing parts of a functional component housing and are usually made of soft elastomers, which are positively arranged between the housing parts to prevent ingress of dirt, moisture, etc. Highly effective seals have labyrinths formed which lead to asymmetrical designs of the mechanical housing interfaces of the housing parts. This complicates the assembly of the functional component housing.

From DE 199 05 952 A1 a distribution box with a seal is known. The distribution box comprises a housing lower part and a functional housing upper part. Fieldbus cables with fieldbus cables and supply voltage cables are routed through the PG screw connection and openings in the housing wall into the interior of the housing base. Likewise, power cables are led by PG gland into the interior of the housing base. The upper housing part is firmly connected to the lower housing part by means of detachable screws. At a parting surface between the upper housing part and the lower housing part, a seal that can be lost is arranged.

It is therefore an object of the present invention to provide an easier-to-install functional component housing. This object is solved by the objects with the features according to the independent claims. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

The present invention is based on the recognition that the assembly of the functional component housing can be simplified by a seal which has been manufactured from two differently elastic materials. According to a first aspect, the object is achieved by a functional component housing having two housing parts and a seal arranged between the housing parts, wherein the seal comprises a base body made of a first material and attached to the base seal member made of a second material, wherein the second material is elastic than the first material is. As a result, the technical advantage is achieved that the base body of the seal stabilizes the seal during assembly, while the sealing element of the more elastic material ensures a reliable sealing effect by its elastic deformability.

The functional component housing, for example, functional elements of automation technology behausen, such as a power supply, a frequency converter, a terminal block for electrical lines. The functional component housing may be used for functional units of a component building system, which may be a fieldbus system. In an advantageous embodiment, the sealing element is formed symmetrically to engage in two opposite housing grooves of the functional component housing. As a result, the technical advantage is achieved that the seal has no preferred orientation, which dictates a mounting orientation. Thus, the assembly is further simplified.

In a further advantageous embodiment, the sealing element has a first subelement and a second subelement, the first subelement being arranged on an upper side of the base body and the second subelement being arranged on an underside of the main body. As a result, the technical advantage is achieved that the sealing element has a particularly simple and stable construction. This simplifies assembly.

In a further advantageous embodiment, the base body has a centering dome. This achieves the technical advantage that the seal with the centering dome can be inserted into corresponding holes of the functional component housing, wherein the seal is positioned during assembly by the engagement of the centering dome in the hole. This simplifies the assembly of the functional component housing. In a further advantageous embodiment, the centering dome is made of the first material. As a result, the technical advantage is achieved that the Zentrierdom not deformed during assembly, which would complicate the assembly. Thus, the assembly is simplified.

In a further advantageous embodiment, the centering dome is integrally formed on the base body. Thereby, the technical advantage is achieved that the seal has a particularly simple structure and, for example, may be integrally formed. In a further advantageous embodiment, the centering dome forms a coding which predetermines an orientation of the two housing parts during the assembly of the functional component housing. As a result, the technical advantage is achieved that incorrect assembly is excluded by a faulty orientation. In this case, the coding further acts as a guide which predetermines an assembly movement for connecting the two housing parts.

In a further advantageous embodiment, the seal is rectangular in shape, and the centering dome is arranged in a corner region of the seal. As a result, the technical advantage is achieved that the seal has a particularly simple structure and therefore is particularly easy to manufacture.

In a further advantageous embodiment, the centering dome is formed symmetrically to engage in two opposite holes of the two housing parts. As a result, the technical advantage is achieved that the centering engages here in a hole, which is assigned to a respective housing part of a functional component housing, and so facilitates the guided assembly of the second housing half after mounting the seal on one of the housing halves. Thus, the production is simplified.

In a further advantageous embodiment, the centering dome comprises a bore for the housing screws, which are captively inserted in a housing part, for example in a cover or in a housing upper shell or in a housing lower shell. As a result, the stability of the centering dome during insertion is increased during assembly. Furthermore, a length of the pre-guide can be increased during the joining of the housing parts.

In a further advantageous embodiment, the seal has a hole for a screw. Thereby, the technical advantage is achieved that by passing the screw through the hole, the seal can be fixed during assembly to a housing part of a functional component housing. This simplifies assembly, since then the seal is attached to the housing part.

In a further advantageous embodiment, the hole is arranged in the base body. As a result, the technical advantage is achieved that the seal is not deformed by the insertion of the screw, since the base body is made of the harder, first material.

In a further advantageous embodiment, the seal has a marking tab which protrudes after assembly of the seal on the functional component housing. The label tab may have a label. As a result, the technical advantage is achieved that an immediate function assignment is given to the functional component housing. According to a second aspect, the object is achieved by a functional component housing set having two housing parts and a seal which can be arranged between the housing parts, the seal having a base body of a first material and a sealing element of a second material fastened to the base body, wherein the second material is more elastic than the first material is. As a result, the technical advantage is achieved that the base body of the seal stabilizes the seal during assembly, while the sealing element of the more elastic material ensures a reliable sealing effect by its elastic deformability. According to a third aspect, the object is achieved by a functional component housing with such a seal. This achieves the technical advantage that the body of the gasket stabilizes during assembly in the gasket while the sealing element of the more elastic material ensures a reliable sealing effect by its elastic deformability.

According to a fourth aspect, the invention relates to a functional component or a functional component lower part having a housing lower shell and a connection device inserted therein for receiving electrical contacts of a functional component or functional component upper part which can be placed thereon. The lower housing shell is surface-mountable and, for example, intended for wall mounting. Further embodiments will be explained with reference to the accompanying drawings. Show it:
