Definitions

  • the invention relates to a contact spring arrangement according to the preamble of claim 1 and an electrical apparatus with such a contact spring arrangement.
  • the invention is therefore an object of the invention to provide a contact spring arrangement, which gives good usability and the use of plugs of different types allowed.
  • the spring means can be designed such that an optimal function of the contact tongues is also given for different pins and in particular for the insertion and contact resistance ,
  • the spring arms of the opposite spring means facing away from each other and the spring bars are pointing towards each other.
  • the contact tongues are also provided in the insertion direction with a V-shaped slot, which results in round-shaped supports of the tongues for round connector pins.
  • the use of the contact spring arrangement is preferably carried out at mains voltage sockets.
  • Figure 1 shows a perspective view of a contact spring assembly 1, on which also still a terminal 20 is arranged, which, however, in the present case is only partially shown and does not form the subject of the present invention.
  • a contact spring arrangement 1 has a base 4 on which two wall parts 2 and 3 are preferably integrally formed.
  • spring means 10 and 11 are further arranged, which opposing contact tongues 5 and 6 carry, between which the pin of a plug, not shown in Figure 1 can be inserted.
  • the spring means 10 on the wall 2 in this case have spring arms 12 and 12 'on both sides of the contact tongue 5 and a spring bar 13 which connects the spring arms 12 and 12', and on which the spring tongue 5 is arranged, and upwards to their free End 7 extends.
  • spring arms 14 and 14 ' are provided, which are interconnected by means of the web 15, from which the contact tongue 6 extends counter to the insertion A forward towards its free end 8.
  • the insertion direction A which corresponds to the direction of movement of a pin, from the front, ie from the free ends 7 and 8 of the contact tongues ago, back to the webs thirteenth and 15 of the contact spring assembly is pushed back between the tongues 5 and 6.
  • the spring means 10 and 11 are preferably integrally formed with the wall 2 and 3 as shown and bent inwardly from the front end thereof, resulting in the preferred arcuate coupling of the spring arms to the respective wall.
  • Figure 2 shows the contact spring assembly 1 from above, in which case the "front” is the area of the free ends 7 and 8 and “back” the area of the base 4.
  • like reference numerals designate used the same elements.
  • FIG. 3 shows a vertical sectional view along the line AA of Figure 2. It can be seen here is the spring means 11 with its spring arms 14 and 14 'side of the contact tongue 6, which is connected at its one end to the spring bar 15 of the spring means and at its other end. 8 is free and protrudes beyond the spring means 11.
  • a V-shaped recess 8 ' is arranged, whose function it is, when inserting a round contact pin between the contact tongues 6 and 5, which preferably also has such a recess 7 ', to give a linear engagement of the edges of the respective recess on the round contact pin and thus a particularly good contact and a reduced friction during insertion of the round pin.
  • the spring arms 12 of the spring means 10 are designed so that they extend after the arcuate bend, with which they are bent away from the wall 2, with respect to the opposite spring arms 14, and 14 ', so that the respective spring arms 12 and 14, and 12 'and 14', pointing away from each other.
  • This can be seen in Figure 1 and particularly well in the side view of Figures 4a to 4d, which represent the insertion of a pin 21 in the contact spring assembly.
  • 4a shows the contact spring arrangement 1 in the rest position with the pin 21 arranged above the latter.
  • the spring arms 12 and 14 of the spring means 10 and 11 running away from one another in the insertion direction A in the rest position can be seen.
  • the spring webs 13 are further away and 15 are arranged to run toward each other, so in turn so bent relative to the spring arms 12 and 14, that results in an opposite course.
  • the spring bars 13 and 15 protrude the contact tongues 5 and 6 from the front and run in the rest position substantially parallel to each other.
  • Figure 4b now shows the initial insertion of the pin 21 between the contact tongues 5 and 6.
  • the pin is in the example shown a rectangular cross-section pin with rounded corners and with dimensions of about 4 mm x 5 mm. As already mentioned, however, a round pin of eg 4 mm diameter could be inserted.
  • Figure 4b shows an insertion of about 3 mm depth between the reeds, which spread apart.
  • the insertion takes place only between the contact tongues 5 and 6, that is, to the wall 2, and 3, subsequent bent portions of the spring means 10 and 11 and the spring arms 12 and 14 are laterally of the Contact tongues 5 and 6 spaced so that they do not form the contact area and thus do not touch the pin 21.
  • the initial insertion according to Figure 4b is a slight insertion by spreading the tongues and in Figure 4c, which represents a dipping of the pin by about 7 mm, a concern of the tongues on the pin 21 approximately but not quite parallel to the pin, said Spring bars 13 and 15 still slightly towards each other, whereby the full contact force of the tongues 5 and 6 has not yet been reached and a slight insertion is still possible.
  • FIG. 4 d shows the end position in which the pin is inserted approximately 10 mm deep into the contact spring arrangement 1.
  • the spring bars 13 and 15 are thereby forced by the pin 21 in a no longer facing each other, or parallel, position, which by the corresponding bending of the contact tongues 5 and 6 to the webs 13 and 15, a strong pressing of the tongues 5 and 6 to the pin 7 and thus gives a high contact force, which is desirable when fully inserted pin. It is thus apparent that the fact that the contact area is formed only by the tongues 5 and 6 and the webs 13 and 15, the spring means can be chosen so that a slight insertion together with a high contact force in the end position in a simple manner can be realized.
  • Figure 5 shows the open enclosure 24 of a mains voltage outlet, in which three contact spring arrays 1, 1 'and 1 "are arranged in the housing, not shown is the upper end of the enclosure, which covers the contact area for the contact spring arrangements and only for the pins Furthermore, of course, openings 25 are provided, through which the connection conductors for the contact spring arrangements to the connection terminals 20 can be guided.
