The invention relates to a plug connector which has a first type of contact and a second type of contact.
There are already known various plug connectors in which various types of contact are provided. Hence, there can be inserted various complementary plug connectors which have differing tasks, for instance transmitting an electrical supply power or transmitting data signals.
It is the object of the invention to provide a plug connector which makes it possible to directly poll data from an electrical device, for instance from automation devices such as a control cubicle.
According to the invention, a plug connector comprises a housing including an accommodation chamber, and a support plate which is arranged in the accommodation chamber and divides the latter in first and second sections. A first type of contact is arranged in the first section and a second type of contact is arranged in the second section. The second type of contact is a USB coupling. It is possible to directly connect a PC or a monitor to the USB coupling, in order to e.g. read out the condition of the automation device or malfunction data.
According to the preferred embodiment of the invention provision is made that two USB couplings are provided which are mounted to the support plate so as to face away from each other. The USB couplings are surrounded by one shield each, a spring element being provided which connects the shields with each other. Such spring element is preferably used to connect the shields of the USB coupling with the housing, which likewise is made of the electrically conductive and, hence, shielding material.
According to the preferred embodiment of the invention the two USB couplings are surrounded by an insulating body which is provided with a cut-out, the spring element projecting through the cut-out and resting against the housing. In this arrangement, the spring element is preferably provided with a raised middle section projecting through the cut-out towards outside. For reliably making contact with the housing there may be made provision that the middle section has several contact-tabs which are bent off at an angle such that they touch the housing with a sharp edge.
According to the preferred embodiment of the invention provision is made that the support plate is freely placed in the accommodation chamber and indirectly secured by means of a fixing screw which right through the housing engages into the first type of contact mounted to the support plate. This makes it possible to secure the entire subassembly, comprised of the two USB couplings, the support plate and the first type of contact, in the housing by means of one single screw, so that there will be a low mounting expenditure.
It is preferably provided for that the support plate is a circuit board. This allows to electrically connect the two USB couplings without external cables. It is preferably provided for that the housing has a mounting flange. This allows the plug connector to be fixedly connected at low expenditure on the wall of a control cubicle, for example, so that there the PC can be connected, if the need arises, by means of which the desired data can be read out.
In
Formed in the interior of the housing 12 is an accommodation chamber 16 into which an assembly unit shown in
Each USB coupling 22 has a shield 24 which is formed by a sheet metal housing. The two shields 24 of the USB couplings are electrically conductively connected with each other by a spring element 26 (see
The spring element 26 is pressed against the shields 24 of the USB couplings by an insulating body 28 made of plastics. The insulating body 28 is fastened to the support plate 18 through two solder-in clips 29 and has a cut-out 30 through which extends the middle section of the spring element 26 including the contact tabs 32.
During assembly of the plug connector, the preassembled assembly unit shown in
As the support plate 18 is used for dividing the accommodation chamber 16 in first and second sections, there will be obtained a particularly clearly laid out structure of the plug connector according to the invention, resulting in advantages during equipping the support plate with the USB couplings and the socket insert, as well as in a particularly simple placement of the resultant assembly unit in the housing 12.
