Definitions

  • the present invention relates to a pluggable electrical connection for the electrical connection of the terminals of two adjacently arranged electrical apparatuses with at least two mounted in an electrically insulating connector housing out of the connector housing male members, which are intended for insertion into the spring terminals of the two spring-loaded terminals.
  • the object of the present invention is to propose an electrical connection of the type mentioned, which is easily inserted and disconnected and is suitable after insertion for the management of all practically occurring currents.
  • each male has an insertable behind the clamping spring Aufstoss forest and a spring-loaded, in the open by the Aufstoss forest before reaching its end position electrical connection opening of the clamping spring terminal pin.
  • the two-part male allows for insertion of the male in the equipped with a spring clamp terminal of an electrical apparatus, the push-in pin penetrating behind the curved point of the tension spring deflects the tension spring and opens the connection opening of the tension spring for the connecting pin moved along with the push-up pin.
  • the opening force decreases on the tension spring and the tension spring clamps the pin to the terminal rail of the terminal.
  • the electrical connection point is not supported on plastic parts of the connection terminal, so that the permissible current load is not determined by the plastic parts of the connection terminals, as is also the case with normal, operational use of the spring-type terminal.
  • test plug for terminal blocks with a two-part plug-in device.
  • this test plug is a connector housing, provided on which a strut-containing plug-in device for locking in an access opening of a terminal block housing and contacted with a scholarux the busbar of the terminal.
  • This arrangement is only suitable for a test plug, which only temporarily and briefly make an electrical connection to the live parts of the device under test.
  • This test plug is unsuitable for a permanent connection between two electrical appliances.
  • the tip of the inventive Aufstossrozes may have a thickening with an inserting behind the clamping spring one of the clamping spring facing inclined surface.
  • the attached at the top of the Aufstoss forestes thickening and the introduction of the Aufstoss reconstructes behind the clamping spring facilitating oblique surface secure opening of the electrical connection opening on the clamping spring, and easy insertion of the plug connection.
  • the Aufstoss may be formed at the two end portions of a fastened in the connector housing U-shaped Materialstossbügels.
  • the production of such a Materialstosssbügels is inexpensive possible.
  • the Aufstoss are advantageously made of metal and are individually inserted into the connector housing.
  • a metal bursting pin can simply be pressed into the connector housing.
  • the Aufstoss may also consist of plastic and molded to the connector housing.
  • connection pins may be formed at the two end regions of a U-shaped connection connection. This arrangement results in a simple manufacturing process.
  • connection pins can be located at the two end regions of the U-shaped connection connection which are resilient by means of bending points. This is a simple and inexpensive arrangement.
  • connection can be attached directly to the connector housing. This measure results in a cost-effective pluggable connection.
  • connection is advantageously attached to the terminal bracket.
  • connection can be fastened by a spring on the connector housing.
  • the spring allows a precisely predeterminable suspension, whereby the insertion of the terminal pins in the connection opening can favors grounded.
  • Fig.1 shows from the side and Fig.2 from the front the arrangement of three adjacently arranged and to be electrically connected devices.
  • a busbar connection point 1 is connected to a pluggable electrical connection 2 with the terminals of a Leisiungsschalters 3 and the output side terminals of the power sleepers 3 with another pluggable electrical connection 4 with the terminals of a contactor 5 electrically conductive.
  • the other not shown electrical connection cables are connected to the output terminals of the contactor 5.
  • the Parallel connection of several fields shown in Figures 1 and 2 is possible if necessary.
  • the pluggable electrical connection described here can be used for any other equipped with spring terminals combination of apparatus.
  • FIGS. 1 and 2 The electrical connection points of all three apparatuses shown in FIGS. 1 and 2 are provided with spring-type terminals.
  • Figure 3 shows two spring terminals with a serving for their electrical connection pluggable electrical connection before plugging partially in section.
  • the spring clamp is arranged in the electrically insulating housing 6 of an apparatus not shown here. It comprises a clamping spring 7, which consists of a bent, electrically conductive material and consists of a bent region 8, a first end region 9 terminating the bent region 8 and another traction region 10 provided with a window and guided through the first end region 9.
  • the not visible in Figure 3 window in the tension region 10 of the clamping spring 7 includes the electrical connection opening in the clamping spring 7.
  • connection opening is opened to insert a connecting wire by inserting a screwdriver behind the curved portion 8 of the clamping spring 7 and the tension region 10 of Clamping spring 7 pushes out of the end portion 9.
  • This connection method is not feasible with a pluggable electrical connection, because the plug housing 11 prevents the insertion of a screwdriver behind the curved portion 8 of the clamping spring 7.
  • a pluggable connection 2, 4 with two-part plug-in elements is proposed.
  • the first male is an attached to the connector housing 11 Aufstossbuild 12, which is inserted behind the clamping spring 7.
  • the electrical connection opening of the clamping spring 7 is thereby released.
  • the electrical connection causing pin 13 is inserted.
  • the tensile force of the clamping spring 7 on the tension area 10 alone is effective and pulls the inserted into the connection opening of the clamping spring 7 pin 13 to the busbar 14 of the terminal, whereby the desired electrical connection is formed.
  • This basic structure of a spring-loaded terminal and the pluggable electrical connection remain in the embodiments described below unchanged. The corresponding reference numbers are also retained.
  • the plug-in connection consists in the arrangement according to Figure 3 of a connector housing 11 made of electrically insulating material, a U-shaped Aufstossbügel 15 and a mounted on the Aufstossbügel 15 by welding U-shaped connection connection 16.
  • the U-shaped connection connection 16th carries at its two end portions of the pins 13. Experiments have shown that the pins 13 must be sprung to achieve the proper functioning of the pluggable electrical connection. The suspension of the connection pins 13 is secured by the bending points 17 in the connection connection 16.
  • connection connection 24 is also attached directly to the connector housing 21 here.
  • a spring 27 is inserted between the connector housing 26 and the connection connection 25 for the suspension of the connection connection 25.
  • Fig.7 shows the pluggable electrical connection in the inserted, operational state. This arrangement corresponds to the arrangement shown in Figure 6 prior to insertion of the connection.
