Description

The invention relates to an electrical connector with an insulating connector housing, in which a ribbon cable and a round cable are conductively connected to each other.

Building automation is becoming increasingly important. It refers to all monitoring, control, regulation and optimization facilities in buildings, the aim being to perform functional processes across industries independently according to predetermined parameters or to simplify their operation or monitoring. For this purpose, all sensors, actuators, controls and consumers and other technical units in the building are networked together and provided with control units.

Especially for the retrofitting of existing buildings is assumed to be known to use for networking of sensors and actuators extruded ribbon cables. Such connection systems, which include the methods "crimping, piercing, as well as welding and soldering" are common, especially in the office equipment for the production of automatically produced large series. However, a practicable connection system of ribbon cables for applications on a construction site during a building installation is not known.

So far, the ribbon cable on the construction site of the provided, rolled-up by meter individually cut to the desired length, cut off and then stripped off the two ends, for example, one of the 4-pin ribbon cable. This is possible with a commercially available wire stripper, equipped with a special blade adapted to this 4-pole cable, still on the construction site. Now it is important to connect the exposed ends of the flat conductor with a plug-in system, which is suitable for connection to the sensors as well as to existing switches and control units. In particular, in the renovation of a building in which some of these present components are installed in the conventional technique using rigid round installation wire (round cable), it is necessary to consider this fact when connecting the sensors, etc. As has been shown, however, it is not economically and technically possible with the known plug-in systems to connect all existing switches and actuators already on the market.

The need to consider round cables when connecting sensors, etc. also applies to new construction projects if a building automation is planned for them. In such cases, when laying cables, conduits are preferred in which the known data lines J- (ST) Y are easier to install.

A plug-in system that is able to electrically connect a ribbon cable with a round cable goes out of the DE 10 2004 020 958 B3 out. However, with the connection terminal described there, it is not possible to transfer different potentials present in the ribbon conductors to separate round conductors.

In connection with the connection of components containing rigid circuit boards as carriers of a printed circuit pattern with electronic components, it is also known from the cited document to provide terminals with solder pins, which can be inserted into correspondingly arranged holes in the board and soldered.

It is also known to use the holes in the boards for attaching a so-called. Tub plug. Such trough plugs are equipped with contact pins, which project into the bores of the board and are soldered therein and form the connection for a plug. The contact pins are located in pin holders, to which there is a diverse socket program. These sockets are designed so that they use a contact via the metallic spring force of the socket on the individual contact pin of the pin carrier. Finally, these socket contacts must still be attached to the respective conductor. Due to the well-known crimp technology, this is possible both for ribbon conductors and round wire conductors. However, the necessary tools and the processing of each conductor of a 4-pin line on the site is associated with high technological complexity and time-consuming handling. After this "hitting" (technical term in the cable assembly) of each individual line now every single contact part must be inserted into a connector housing. The assignment of the 4 cable strands in the plug housing must be observed. An incorrect assignment (reverse polarity) possibly leads to the destruction of the sensors, at least to a wrong function.

Shortened, this process can be illustrated with the following steps: Solder connection PCB to the contact pin of the bath plug Contact pin of the bath plug to the socket contact Socket contact Crimp connection to the FFC

The object of the invention is to provide a connector which avoids the disadvantages of the known designs with a simple structure and is applicable in many technical fields.

To solve this problem, it is proposed that the plug housing consists of a base part and a lid, wherein the lid relative to the base part in a the inside of the base accessible making open position in which a ribbon cable can be fed, and in a locked closed position in which the is moved, that the base part has a receiving slot for a provided with stripped flat ribbon conductors ribbon cable, that in the base part in each case below a stripped flat conductor, a first contact part is housed, and that the cover at a distance of the ribbon conductor and in parallel to a corresponding number of supply openings for a round cable contains, the supply openings are associated with second, extending in the longitudinal direction of the receiving shaft contact parts, which are close to the feed openings known per se Einsteckschuhe for the round wire conductor the round cable and in the other, located exactly above the first contact parts end portion are designed as presser, the areas of the second contact parts are behind the Einsteckschuhen compared to the areas before angled down so that the Andrücker already contact the first contact parts before the lid completely is closed and load with a closed lid with sufficient bias.

The connector according to the invention offers several advantages in that he

• - represents a compact assembly;
• - consists of few components;
• - Consists of a cheap plastic housing (base and lid) and easy to produce metal parts (first and second contact parts);
• - proves to be extremely practical especially for assembly work on a craftsman site;

According to claim 2, it is proposed that the support surface for a ribbon cable in the receiving shaft of the base part has at least one elevations for the positionally accurate positioning of the ribbon cable, which is provided with at least one in size and distance from each other as well as the stripped ends of the ribbon conductor adapted breakthroughs.

As a result, a precise positioning of the ribbon cable with the stripped flat band conductors in the base part is given in a simple manner. Characterized in that according to claim 3, the cover is pivotally mounted on the base part, the presser are pressed in a vertical direction on the first contact parts, whereby a secure fixation and a galvanically conductive connection of the ribbon conductor of an inserted ribbon cable is given to the first contact parts.

To couple the connector directly to the trace of a board and thus extend the applicability of the connector to sensors with integrated circuit boards are provided according to claim 4, the first contact parts for contacting the trace of a board with a Einsteckzone, facing away from the cables Protruding end wall of the base part, wherein the Einsteckzonen are formed transversely to its longitudinal direction elastically yielding. The compliant design of the insertion zones allows manual coupling of the connector to the board without significant effort while safe contact without solder joint.

The invention will be explained in more detail below with reference to drawings. Show it:

1 a connector with a connected ribbon cable in ready-to-use condition,

1a a ribbon cable 4-pin, with stripped conductor tracks and 2 punched openings

2 the connector according to 1 with partially raised lid,

3 a connector with a connected round cable in ready-to-use condition,

4 a connector with a connected ribbon cable and a connected round cable with partially swung lid,

5 the base part of a connector with integrated first contact parts with a plug-in zone,

5a a single, first contact part with insertion zone,

6 the base part of a connector with integrated first contact parts without insertion zone,

6a a single, first contact part without insertion zone,

7 the cover of a connector with integrated second contact parts,

8th one of the second contact parts in the lid according to 7 .

8a a single one of the second contact parts

Like from the 1 to 4 it can be seen consists of molded plastic connector housing 1 a connector from a base part 2 and a lid 3 ,

In a raised area of the base part 2 are in its longitudinal direction 4 metallic first contact parts 4 introduced parallel to each other. Their distance from each other corresponds to the distance of the ribbon conductor of a correspondingly associated ribbon cable.

The first contact parts 4 protrude in a first version on both sides of a certain measure of the raised portion of the base part 2 out. The outwardly projecting areas of the first contact parts 4 are according to 5 as a plug-in zone 4a configured, which in correspondingly arranged holes of a not shown, for. B. in a sensor housed circuit board with conductor can be inserted to make a contact with the conductors. With this version, the connector can thus be arranged directly on a circuit board. So about the plug-in zones 4a on the one hand, a secure contact is given and on the other hand, the force for inserting the Einsteckzonen in the holes of the board for the craftsmen on a construction site is not too high, are the Einsteckzonen 4a designed resiliently in the manner of a Nadelöhrs, which is open on one side.

In a second version that out 6 shows, the first contact parts 5 no insertion zone. This is useful if no contact with boards is intended with the connector equipped with it.

Like from the 2 . 4 . 5 and 6 shows close to the raised area of the base part 2 a top open receiving shaft 6 in, in which the inner end portions of the first contact parts 4 . 5 protrude. The receiving shaft 6 is for receiving a ribbon cable 7 provided, whose 4 ribbon conductors 7a with the inner end portions of the first contact parts 4 . 5 contacting should be brought together. 1 . 2 and 4 show such on the support surface 6a of the receiving shaft 6 launched ribbon cable 7 , So that the ribbon cable 7 in the receiving shaft 6 can be stored properly, is its bearing surface 6a with 2 surveys 6b and the ribbon cable 7 with 2 breakthroughs 7b Mistake. The location of the surveys 6b and the breakthroughs 7b is matched to one another in such a way that the stripped flat strip conductors 7a on the inner end portions of the first contact parts 4 . 5 come to the edition.

In particular according to 1 and 2 is the raised area of the base part 2 on the shaft side with an undercut 2a provided in the lid 3 with its matching extension 3a intervenes. Thus, the lid 3 swiveling on the base part 2 stored so that he between a free access to the receiving shaft 6 open position in a closed position in which he the receiving shaft 6 closes from above, can be pivoted. In the closed position is the lid 3 with its locking rail 3d in the catch hook 2 B of the base part 2 locked.

The receiving shaft 6 mm is not only above but through an end wall 3b of the lid 3 also closed at the side.

The further construction of the lid 3 is from the 7 and 8th seen. After that are above the ribbon conductor 7a in the front wall 3b 4 feed openings 3c for each round cable 8th , Behind each of these feed ports 3c is a second contact part 9 in the lid 3 introduced, immediately behind the feed opening 3c as a known Einsteckschuh 9a is trained. Behind it is the second contact part 9 from its previous parallel to the surface of the lid 3 extending direction so angled downwards that its free, as a presser 9b trained end during the closing of the lid 3 on the in the receiving shaft 6 protruding end portion of the first contact part 4 . 5 meets and burdened with increasing force.

Is appropriate 3 and 4 the lid 3 for holding 4 round cables 8th provided, these are after stripping the round wire conductor 8a in the beginning of the base part 2 separate lid 3 plugged in. There receives the round wire conductor 8a over the insertion shoe 9a Contact with the second contact part 9 , Subsequently, the lid 3 articulated with the base part 2 connected and pivoted in its closed position. In this position ( 3 ) is the round wire conductor 8a electrically conductive with the first contact part assigned to it 4 . 5 connected. Is this a first contact part? 4 with a press-fit zone 4a so is the round wire conductor 8a connectable to the track of a board. The same applies if the connector only in the receiving shaft 6 a ribbon cable 7 has recorded ( 1 ). Is this a first contact part? 5 , which has no press-in zone, and is located in the receiving shaft 6 also a ribbon cable 7 ( 4 ), the connector realized an electric conductive connection between a round wire conductor 8a and a ribbon conductor 7a ,
