Definitions

  • the invention relates to an arrangement for plugging in power supply devices under voltage, consisting of a contact pin and a contact socket, the contact pin having a contact tip and a main contact body electrically separated by an intermediate piece.
  • the arrangement is used in the power supply of electronic systems.
  • Arrangements according to the preamble are known for the power supply of small devices, such as pocket calculators, cassette recorders, electronic games and the like, which are usually operated with a DC voltage of 3 to 15 volts.
  • small devices are usually supplied with their operating voltage from a separate power supply unit.
  • These power supplies have a standardized contact pin, which consists of a contact tip, an insulating piece and a main contact. The supply voltage (plus and minus potential) is transferred via this contact pin by inserting the contact pin into a socket on the small device.
  • Power supplies for computers must be plugged into or pulled out of the system while they are live. This means that the power supply must be exchangeable without the entire system being switched off. Although more power supplies are used in each system than would be absolutely necessary to cover the power requirement, so that if one such device fails, the other power supplies can also take over the power, but it is difficult to replace the defective power supply during continuous operation.
  • a particular advantage of the arrangement according to the invention is the simple, quick and problem-free connection of the power supply unit to be reinserted into a running system without voltage dips.
  • the slow insertion of the power supply into the system automatically ensures that the capacitors are properly charged and that a complete and final connection between the system and the power supply takes place only after charging. Due to this inevitability, power supply unit replacements can also be carried out easily and easily by auxiliary staff. Special knowledge is not required.
  • the contact pin used as a connecting part is simple and inexpensive to produce as a turned part.
  • FIG. 1 shows the contact pin and FIG. 2 the contact socket of the arrangement according to the invention.
  • the arrangement for plugging power supply devices under voltage contains a contact pin (Fig. 1) and a contact socket (Fig. 2).
  • the contact pin is usually located on the power supply that is to be connected to an already operating system.
  • the contact socket for receiving the contact pin is arranged at a suitable point in the system. Depending on the design, the contact pin in the system and the socket in the power supply can also be attached.
  • the tubular contact socket consists of a housing 1, on the lower part of which a thread 2 is attached for screwing into a frame (on a busbar). Inside the housing 1 there is a cup-shaped contact part 3 which is resiliently mounted in the housing 1 via a corrugated spring 4. The electrical connections of the contact socket are not shown in the drawing.
  • the arrangement according to the invention for plugging in power supplies includes the contact pin according to FIG. 1.
  • This contact pin has a contact tip 5 which is tapered at the lower end for better insertion into the contact socket.
  • An intermediate piece 6 connects to the contact tip 5 and the main body 7 of the contact pin is arranged above it.
  • This main contact body 7 has a threaded bore 8 for mechanically attaching the entire contact pin to a busbar.
  • Contact tip 5 and main contact body 7 are made of brass, for example.
  • the cylindrical intermediate piece 6 between the contact tip 5 and the main contact body 7 has a cantilever term projections, which engage in corresponding recesses on the main contact body 7 and the contact tip 5.
  • the intermediate piece 6 has a longitudinal opening (cavity) into which a resistor 9 is inserted.
  • the resistor 9 engages in a blind hole in the contact tip 5 and in a blind hole in the main contact body 7.
  • the lower blind hole in the contact tip 5 is conical at its ends, so that there is a good contact between the resistor 9 and the contact tip 5 and thus a close galvanic connection.
  • the resistor 9 in the longitudinal opening of the intermediate piece 6 has a commercially available, rod-like shape. But it can also consist of metal wire with rounded ends. Such a design is also conceivable that a conductive material is inserted into the intermediate piece 6.
  • the inside of the intermediate piece 6 is made conductive by incorporating metallic material. The resistance does not have to be inserted directly into a longitudinal opening in the intermediate piece. Rather, it can be injected during the manufacture of the insulating material.
  • a separate resistor is advantageously completely dispensed with, ie resistor 9 and intermediate piece 6 form a structural unit.
  • the intermediate piece 6 is made specifically conductive by using special materials. It is also possible to store conductive materials (metal, coal) in the adapter.
  • the power supply unit is supplied with the system current via this contact pin, so that the large filter capacitors at the output of the power supply unit can slowly charge up via the resistor 9. Now the contact pin of the power supply unit is pushed further into the contact socket until the main contact body 7 has contact with the contact part 3 of the contact socket. The system current now flows from the contact socket directly onto the main contact body 7 of the inserted contact pin. The resistor 9 is thus bridged. Now that the filter capacitors are charged, the new power supply can be safely connected to the entire system.
  • the new power supply unit is therefore not yet in operation when it is inserted into the system (electronic system).
  • the filter capacitors are current-limited (via resistor 9) charged by the system voltage, then the resistor is bridged and only then is the supply voltage (mains voltage) switched to the power supply.
