Description

The invention relates to a contact for a plug and / or a socket, in particular for a plug and / or a socket for a trailer wiring.

Contacts are formed as contact pins or contact bushes, and have a contact region, to which an associated second contact is contactable by a contact pin is inserted into an associated contact socket for making an electrical connection, and a connection region, at which the contact with a conductor, for example a cable or wire, is connectable on. It is known to connect the contact permanently, for example by soldering, or releasably, for example by a screw, with the head. The contact is formed of a suitable material to realize a good electrical connection. A female contact may be coated on its outside for insulation. The contacts are for use in a plug or socket in a contact holder can be arranged, which is inserted into a housing of the plug or the socket and / or integrally formed therewith.

It is known for example from DT 26 51 108 A1 to produce a contact pin from a metal sheet by punching and rolling, wherein the contact pin has an open gap extending over the axial length of the manufactured contact pin. Such a contact is easy to produce, but as a rule has only a low surface quality.

It is also known to make contacts for sockets or plugs for trailer cabling as turned parts. However, a production of such contact requires a large amount of material and is therefore usually costly. In addition, an automated production of such contacts is only possible to a limited extent.

It is an object of the present invention to provide a contact which is suitable for a socket or a plug for trailer cabling, has a high surface quality and is easy to produce.

This object is achieved by a contact for a plug and / or a socket, in particular for a plug and / or a socket for a trailer wiring, comprising a contact element with a contact area, which is formed as a contact pin or contact socket and for an electrical connection in a corresponding contact socket can be inserted or placed on a corresponding contact pin, and a connection region, and a connection element with a connection region, which can be firmly or detachably connected to an electrical conductor, and a connection region, wherein the contact element and the connection element are formed as separate components and connected to each other at the connection areas are, and wherein the contact element is a molded by deep-drawing hollow body.

Due to the multi-part configuration of the contact, comprising at least one contact element and a connection element, different materials and / or different production methods can be selected for different areas of the contact, so that different requirements for the respective area can be taken into account. In addition, different contact elements and connecting elements can be connected to each other, thereby obtaining a large number of different variants of the contact with at least partially identical elements.

By producing the contact element by means of deep drawing, a material insert can be significantly reduced compared to a shaping of the contact as a turned part. Due to the achievable high surface quality, it is also possible to store the contact exactly in a contact holder, a bearing can be securely sealed. In the case of contact pins, there is therefore a closed body with a high surface quality, by means of which penetration of moisture into the connection area can be prevented. A production by deep drawing is further generally faster and cheaper feasible than a production as a turned part.

In one embodiment, the contact region and the connection region and / or the connection region and the connection region are formed at opposite ends of the contact element or the connection element. The connection region of the contact element is formed substantially separate from the contact region. However, this does not exclude that the regions in one embodiment partially overlap. In other embodiments, the areas adjoin one another. Also the connection area of the connection element is formed substantially separated from its connection area. Thus, even after connecting the connection element to the contact element in the connection regions, the connection region and the contact region are freely accessible for the respective use.

In one embodiment, the connection element is formed as a stamped / bent part. The connecting element is inexpensive to produce automated. A connection region for a conductor is formed in an advantageous embodiment with clamping elements, for example with one or more clamping arms, in particular with two clamping arms, which can be bent around the conductor. By such clamping elements, it is possible to attach conductors with different diameters at the connection area. The diameter of the conductor can also be greater than the diameter of the contacts in the contact areas. In other embodiments, the terminal region is soldered or otherwise connected to the conductor.

In a further embodiment, the connection element is formed on a carrier tape. A plurality of connection elements can be produced inexpensively automated and connected to a corresponding number of contact elements on the carrier tape. By the carrier tape, the contacts thus present are prepared in a suitable manner for further processing. In one embodiment of the invention, the connection element is connected at a free end of the connection region via a web or the like to the carrier tape.

In a further embodiment, the connection element has a stop which is formed by bending, in particular by rolling, of the stamped / bent part. The stop serves as an embodiment Stop when the contact snaps into a contact holder. The stop cooperates according to an embodiment with a surface on the contact element, wherein a contact can be inserted through a recess in a contact holder and is axially secured by the stop and the surface.

In a further embodiment, the contact element and the connection element are connected by crimping. For the crimp connection, crimp zones, for example depressions, are formed in the contact element and / or the connection element in one embodiment.

In a further embodiment of the invention, the contact element has a substantially cylindrical contact region and a connection region for connection to the connection element. Sockets or plugs for connections between a towing vehicle and a trailer are standardized, for example, according to ISO 7638-1, ISO 12098 and / or ISO 1185/3731. For example, according to ISO 7638-1, the length of a contact area of a cylindrical contact pin is set at 23.5mm and the diameter is 4mm. On the other hand, a configuration of the connection area and / or the connection area is currently not defined by standards and / or other standards. The connection area and / or the connection area can thus be designed freely according to other requirements.

In a further embodiment, the contact element is open at both ends. The contact element is formed as a contact socket.

In one embodiment, the contact element is closed at one end. The contact element is formed, for example, as a contact pin, wherein the closed end is formed, for example, hemispherical or conical. In another embodiment, the contact element is formed as a socket, wherein the closed end forms a connection region for a connection element. When using a contact in a socket which is mounted in the exterior of a vehicle, such as a socket for temporary connection of the vehicle with a trailer, a good seal of the connection area for connection to the electrical conductors is desirable even without plug inserted. By molding the contact element as a deep-drawn part with a high surface quality and at least one closed end, penetration of moisture through contact into the connection region can be prevented.

In a further embodiment, an end of the contact element forming the connection region is open and the connection element can be inserted into the connection region for a connection. The contact element may be formed a contact socket or a contact pin.

In another embodiment, an end of the contact element forming the connection region is closed and the connection element can be placed on the connection region for a connection. The contact element is formed as a contact socket.

In a further development of the invention, the contact element is formed as a contact socket with at least one depressed contact point. By the depressed contact point is an electrical and / or mechanical connection of the female contact to a corresponding contact pin can be improved. Contact points are preferably formed as a deep-drawn part following a shaping of the contact socket.

In a further embodiment, the contact element is formed as a contact socket for receiving a clamping sleeve. By arranged in the contact sleeve clamping sleeve secure contact with a corresponding contact pin can be realized. Due to the high surface quality of the deep-drawn part secure mounting of the clamping sleeve is possible.

In another embodiment, the contact element is designed as a contact socket with at least one contact blade. The contact blades are preferably formed in a deep drawing process for forming the contact socket. In addition, however, it is also conceivable to form the contact blades later in a contact socket.

It is a further object of the invention to provide a method for making a contact.

This object is achieved by a method for producing a contact, comprising the steps: deep drawing of the contact element; Punching the connection element; and connecting the contact element and the connection element. The method can be carried out partially or completely automatically, whereby a high quality can be achieved by the individual steps.

In one embodiment, connection elements are manufactured on a carrier tape. By the carrier tape easy handling of the connection elements during manufacture and an automated transfer is possible.

In a further embodiment, the contact elements are connected to the connection elements on the carrier tape. The thus manufactured contacts are therefore like conventional stamped and rolled contacts weiterverarbeitbar, but have a much higher quality over these.

In a further embodiment, the contacts are wound on the carrier tape on a roll. The individual layers of the roll are covered in one embodiment with intermediate paper or a similar material. In one embodiment, a quality control is performed before winding, for example by video.

In a further embodiment, the contact element and the connection element are connected by crimping. Crimping is also automated.

In a further embodiment, for the production of the contact element first blanks are punched out of a material, deep-drawn the blanked blanks and milled the deep-drawn parts to length. The steps are all automated.

In a further embodiment, the contact elements are manufactured on a machine in various steps. By such a machine, a simple production is possible.

Further advantages of the invention will become apparent from the following description of embodiments of the invention, which are illustrated in the drawings. For identical or similar components uniform reference numerals are used.
