Definitions

  • the invention is based on a contact insert for an industrial connector according to the generic type of independent claim 1.
  • the invention also relates to a system consisting of a connector housing and such a contact insert.
  • Such contact inserts are required when the currents of individual conductors of a multi-core cable have to be divided within the connector. This is the case, for example, with so-called data centers.
  • the so-called neutral conductor of the connected cable within a server rack (engl. data rack) must be divided between the individual units (engl. server units) of the server rack.
  • German Patent and Trademark Office has researched the following prior art in the priority application for the present application: DE 19945317 A1, DE 9307260 U1, DE 19651 171 A1, US 6,162,089 A and US 2004/0166737 A1.
  • the object of the invention is to propose a contact insert for industrial connectors that is safe, compact and easy to connect to a cable.
  • the contact insert according to the invention is intended for use in an industrial connector.
  • Such connectors usually have a rectangular cross section and are used in particular in harsh industrial environments. Accordingly, the contact inserts used usually have a cuboid basic shape with a rectangular cross section.
  • the contact inserts are fastened in the connector housing using a so-called holding frame, for example.
  • the contact inserts can also have means with which they can be fixed directly in the connector housing.
  • the contact insert according to the invention has a connection side for connecting individual conductors of a multi-core cable.
  • the conductors of the cable are connected to the contact insert on this side.
  • the contact insert has a contact side for electrical connection with a mating connector or socket.
  • the contact to the mating connector or to the socket is made on this side.
  • the contact insert has n connection openings for the respective conductors of the multi-core cable on the connection side.
  • the contact insert On the contact side, the contact insert has m contact openings, which enable a mating contact element of a mating connector to access the contact insert or the contact elements located therein.
  • the variables n and m are numbers from the natural number space ⁇ 1, 2, 3, ... ⁇ . According to the invention, the number m is greater than n. This means that there are fewer connection openings than contact openings in the contact insert.
  • the contact insert preferably has a plurality of contact elements.
  • the contact elements each have a connection area for electrical connection to a conductor of the multi-wire cable and a contact area for electrical contacting of a mating contact element of a mating connector or a socket.
  • the connection area of the contact element is arranged in the connection opening and the contact area of the contact element is arranged in the contact opening.
  • the contact elements are advantageously socket contacts.
  • the socket side is provided with axially forward-pointing lamellae, which form a receiving area for a mating contact element designed as a contact pin.
  • connection area of the contact elements is advantageously designed as a crimp connection. This contacting technique has proven itself with such contact inserts.
  • the contact insert preferably has a bridge contact.
  • the bridge contact has exactly one connection area for the electrical connection to a conductor of the multi-core cable.
  • the bridge contact has at least two contact areas for the respective electrical contacting of a mating contact element of a mating connector or socket. This means that the electric currents of a conductor of the connected cable are transferred, bridged or divided over at least two contact areas.
  • This can in particular be the so-called neutral conductor of the cable, which is transmitted to several sub-units of a higher-level device, with the other conductors, the so-called phase conductors, being divided between the respective sub-units of the device. This allows more effective cabling to be implemented.
  • the bridge contact has three, preferably even exactly three, contact areas for the respective electrical contacting of a mating contact element of a mating connector or a socket.
  • the neutral conductor would be bridged or split between three contact areas.
  • the bridge contact is formed from, among other things, a metal plate. At least two contact areas are attached to one side of the metal plate. Exactly one connection area is attached to the other side of the metal plate, so that the contact areas and one connection area are electrically conductively connected to one another.
  • the contact areas are preferably riveted to the metal plate.
  • connection area of the bridge contact advantageously consists of a pin contact which is riveted to the metal plate.
  • a socket contact is attached to the pin contact.
  • the socket contact of the bridge contact is preferably identical to the remaining socket contacts of the contact insert executed.
  • the production costs can be further reduced by using identical components.
  • the contact insert has a PE contact element.
  • Grounding is safety-relevant, especially in an industrial environment, and can be easily implemented using the PE contact element. It is particularly advantageous if the PE contact element is designed identically to the other contact elements of the contact insert. In this case, no other tool is required to connect the PE conductor of the cable to be connected.
  • the contact insert is installed in a connector housing. As already mentioned above, this can be done directly or indirectly via a holding frame.
  • the connector housing is advantageously made of plastic. In this way, in particular, a lighter design of an industrial connector can be realized.
  • FIG. 1 is a perspective view of a contact insert according to the invention
  • FIG. 4 shows a perspective view of a partial element of a bridge contact according to the invention
  • FIG. 5 shows a perspective view of the entire bridge contact.
  • FIG. 1 shows a possible embodiment of a contact insert 1 according to the invention.
  • the contact insert 1 is shown in perspective, with the observer only being able to see the connection side A pointing upwards in this illustration.
  • the corresponding opposite side, the contact side K can be seen clearly in FIG.
  • An electrical, multi-core cable (not shown) is connected to the contact insert 1 .
  • the cable consists of individual conductors (not shown), each of which is sheathed in an insulating manner, with the conductors being distinguishable by their generally standardized sheath colors.
  • the individual conductors are combined in a multi-core cable, which in turn is surrounded by an insulating cable sheath.
  • the individual conductors of the multi-core cable are electrically connected to the connection side A of the contact insert 1.
  • the individual conductors are usually first crimped onto a contact element 3 and then inserted into a connection opening 2 of the contact insert.
  • the contact elements 3 are held or fixed in the contact insert 1 via a cover 5 that can be locked on the contact insert base.
  • the contact side K of the contact insert is intended for electrical connection to a mating connector or socket.
  • the contact side K has contact openings 4 .
  • Mating contact elements of a mating connector or a socket can access the contact elements 3 of the contact insert via the contact openings K.
  • the principle is well known and needs no further explanation.
  • Six contact openings 4 are provided on the contact side K, which allow access to a mating contact element of a mating connector or a socket.
  • connection side A only four connection openings 2 are provided for the cable conductors to be connected.
  • Contact elements 3 are used in the contact insert 1, as can be seen in FIG. 5, for example—although here in connection with a bridge contact 10.
  • the contact elements 3 have a connection area AB, designed as a crimp connection, and a contact area KB, designed as a socket.
  • the contact insert 1 has a PE contact element 6 which is arranged laterally in a contact chamber of the contact insert 1 specially provided for this purpose.
  • FIG. 5 shows an exemplary embodiment of a bridge contact 10 according to the invention.
  • An electrical phase or a conductor of the cable can be transferred to three contact areas KB of the contact insert via the bridge contact 10 .
  • FIG. 4 shows the part of the bridge contact 10 which is responsible for the actual electrical bridging function.
  • the bridge contact 10 has a connection area AB for the electrical connection to a conductor of the multi-core cable.
  • the connection area AB is provided by a contact element 3, as is also used for the non-bridged connections of the contact insert 1.
  • a hollow-cylindrical connection area AB is used for crimping the conductor.
  • the bridge contact 10 has three contact areas KB for the respective electrical contacting of a mating contact element of a mating connector or a socket.
  • the bridge contact 10 consists essentially of an elongated metal plate 7 with rounded end areas. Three contact areas KB are riveted to one side of the metal plate. On the other side of the metal plate 7 is a pin contact 8, which is also attached to the metal plate 7 by riveting. A contact element 3 is plugged onto the pin contact 8, as a result of which a connection area AB for the bridge contact 10 is provided.
  • the contact insert 1 In order to be able to fix the contact insert 1 in a holding frame (not shown) or directly in a connector housing (not shown), the contact insert 1 has holding lugs 9, 9', which have different widths for reasons of polarization.
