Abstract

The invention relates a plug-in connection system (1) for providing a hidden plug-in connection between two contacts (2, 3), wherein a first contact (2), particularly a plug, is connected to a first carrier element (4) that is preferably configured as a printed circuit board, and a second contact (3), particularly a plug socket, is connected to a second carrier element that is preferably configured as a printed circuit board (5). According to the invention the first contact (2) is configured as an elastically deformable spring contact, wherein at least one first stop (8, 9) limits the elastic deformation of the spring contact in the plug-in direction, and at least one second stop (11, 12) limits the elastic deformation of the spring contact perpendicular to the plug-in direction.

Description

Steckverbindunqssvstem

The invention relates to a connector system for providing a concealed connector between contacts of assemblies to be contacted with each other according to the preamble of claim 1.

In mechatronic systems there is often the need to provide a concealed plug connection between contacts of assemblies to be contacted with each other, namely of sub-modules of a mechatronic system to be contacted with each other. In this case, the provision of a reliable, concealed connector is particularly difficult when tolerances between the contacts to be contacted must be compensated. So far, no connector systems are known from the prior art, with which this is possible in a simple manner.

On this basis, the present invention is based on the problem to provide a novel connector system for providing a hidden connector between to be contacted with each other assemblies. This problem is solved by a connector system according to claim 1. According to the invention, the first contact is designed as an elastically deformable spring contact, at least one first stop limiting the elastic deformation of the spring contact in the plug-in direction and at least one second stop limiting the elastic deformation of the spring contact perpendicular to the plug-in direction.

By the attacks of the connector system according to the invention a secure contact between the hidden contacts to be contacted can be realized, even if a tolerance compensation between the contacts to be contacted is required. Furthermore, the elastic deformation of the spring contact is limited by the stops, so as to avoid that the same is plastically and thus irreversibly deformed when contacting and decontacting the contacts.

Preferably, two first stops limit the deformation of the spring contact in the insertion direction, namely a stop when contacting the two contacts and another stop when decontacting the two contacts. Furthermore, preferably two second stops limit the deformation of the spring contact perpendicular to the plugging direction. One of the two second stops is formed in particular by one of the two first stops.

Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawings. Showing:

Fig. 1 is a schematic representation of a connector system according to the invention for providing a hidden connector between contacts of modules to be contacted with each other.

1 shows a schematic representation of a plug connection system 1 according to the invention for providing a concealed plug connection between two contacts 2 and 3 of assemblies to be contacted with each other. In the illustrated embodiment of FIG. 1, a first contact 2 is formed as a plug and assigned to a printed circuit board 4 formed as a first module assembly. A second contact 3 is designed as a socket and assigned to a likewise designed as a printed circuit board 5 supporting element of a second module. The contacts 2, 3 are connected to the respective printed circuit board 4, 5, wherein a connection point of the contact 2, 3 with the corresponding circuit board 4, 5 can be made arbitrary.

The first contact 2, which is designed as a plug, is designed as an elastically deformable spring contact and can be inserted with a tip 6 into a receptacle 7 of the second contact 3, which is preferably designed as a fork contact. According to Fig. 1, the elastically deformable spring contact C-shaped or U-shaped kontuhert. Alternatively, the spring contact can also be contra-S-shaped.

In the exemplary embodiment shown in FIG. 1, two first stops 8 and 9 cooperate with the first contact 2 designed as an elastically deformable spring contact, which limits the elastic deformation of the spring contact in the direction of insertion according to the double arrow 10. The stop 8 limits the deformation of the contact 2 formed as a spring contact when contacting the two contacts 2, 3 and accordingly when inserting the tip 6 of the contact 2 in the receptacle 7 of the contact 3. The stop 9, however, limits the deformation of the formed as a spring contact Contact 2 when decontacting the contacts 2, 3, so when moving out of the tip 6 of the contact 2 from the receptacle 7 of the contact 3. By the stops 8, 9, therefore, the elastic deformation of the spring contact is limited in the insertion direction, so as to prevent the spring contact is irreversibly plastically deformed.

Furthermore, according to the exemplary embodiment of FIG. 1, two second stops 1 1, 12 coincide with the first contact 2 in the form of a spring contact, which limit the elastic deformation of the spring contact perpendicular to the direction of insertion according to the double arrow 13. In the embodiment of FIG. 1, one of the two second stops, namely the impact 12, formed by one of the first two attacks, namely the stop 9.

When contacting the two contacts 2, 3, therefore, the spring contact on the one hand in the insertion direction and on the other hand transversely to the direction of insertion limited by stops 8, 9, 1 1, 12 elastically deformed, on the one hand a safe insertion of the tip 6 of the contact 2 in the receptacle of the contact 3, and on the other hand to preclude a plastic and therefore irreversible deformation of the contact 2. Furthermore, the elastic deformation of the contact 2 when decontacting the contacts 2, 3 is limited.

In the plugged state of the contacts 2, 3, the connector is always under pressure, so that no fretting corrosion on the contact surfaces of the contacts 2, 3 can arise. The connector thus automatically generates a sufficient contact pressure in the contacted state of the contacts 2, 3rd

The stops 8, 9, 1 1, 12 are electrically insulated from the contact 2 designed as a spring contact. As already stated, the spring contact is preferably C-shaped or S-shaped or U-shaped. In particular, the contact 2 is made of flat material, round material or partially rolled round material. The contact 3 is preferably designed as a fork contact. Depending on the application, the contact 3 may also be designed as so-called tip contact.

In the illustrated embodiment, the connector comprises only two contacts, namely a first contact 2 and a second contact 3. In contrast, it is also possible that the connector system comprises a plurality of first contacts 2 and a plurality of second contacts 3. In this case, the connector system is designed as a so-called multiple connector. Bezuαszeichen
