Definitions
- the invention relates to a contact spring arrangement according to the preamble of claim 1 and one electrical apparatus with such a contact spring arrangement.
- EP-A-0 783 776 is a contact spring arrangement known according to the preamble, which for plug connections used in automotive wiring where usually only an occasional loosening of the Plug connection is made.
- a contact spring arrangement known according to the preamble, which for plug connections used in automotive wiring where usually only an occasional loosening of the Plug connection is made.
- the invention is therefore based on the object to create a contact spring assembly which is easy to use and the use of Different types of plugs are permitted.
- the spring means are designed so that an optimal Function of the contact tongues also for different pins and especially for insertion and contact resistance given is.
- An embodiment is particularly preferred where the spring arms of the opposite spring means pointing away from each other and the spring bars towards each other to be pointing. This results in a particularly good insertion with high contact force when the pin is inserted.
- the contact tongues in the direction of insertion are also preferred provided with a V-shaped slot, what round Plug pins line-shaped supports of the tongues results.
- the contact spring arrangement is used preferably with mains voltage sockets.
- Figure 1 shows a diagram a contact spring arrangement 1, on which also a Terminal 20 is arranged, which is present is only partially shown and not the subject of the present invention.
- connection arrangement 20 an electrical conductor can be attached which is thereby electrical with a contact pin is connected, the insertion direction A in the contact spring assembly 1 is plugged in, as will be explained later is explained.
- the contact spring arrangement 1 has in the shown Example a base 4 on which two wall parts 2 and 3 are preferably formed in one piece.
- On the wall parts 2 and 3 are also spring means 10 and 11 arranged, which opposing contact tongues Wear 5 and 6, between which not in Figure 1 illustrated pin of a plug can be inserted can.
- the spring means 10 on the wall 2 have spring arms 12 and 12 'on both sides of the contact tongue 5 on and a spring bar 13 which connects the spring arms 12 and 12 ', and on which the spring tongue 5 is arranged, and extends up to its free end 7.
- the spring means 10 and 11 are preferably in one piece as shown formed with the wall 2 and 3 and from their front end bent out inwards, which is the preferred arcuate coupling of the spring arms to the respective Wall results.
- Figure 2 shows the contact spring arrangement 1 of above, where "front” is the area of the free ends 7 and 8 is and “behind” the area of the base 4. Otherwise denote in Figure 2 and in the other figures same reference numerals as used until now, the same Elements.
- Figure 3 shows a vertical sectional view along the line A-A of Figure 2. It can be seen the spring means 11 with its spring arms 14 and 14 'laterally the contact tongue 6, which at one end with the spring bar 15 of the spring means is connected and on its other end 8 is free and via the spring means 11 protrudes.
- 6 is in the contact tongue a V-shaped recess 8 'arranged, its function it is when inserting a round contact pin between the contact tongues 6 and 5, which preferably also has such a recess 7 ', a linear one Concern the edges of the respective recess on round contact pin and thus a special good contact and less friction when inserting of the round pin.
- Embodiment are the spring arms 12 of the spring means 10 designed so that after the arcuate Turn with which they are bent away from wall 2 with respect to the opposite spring arms 14, or 14 ', run such that the respective spring arms 12 and 14, or 12 'and 14', facing away from each other.
- FIG. 1 shows the side view of Figures 4a to 4d, which the Inserting a pin 21 into the contact spring arrangement represent.
- Figure 4a shows the contact spring arrangement 1 at rest with the one arranged above it Stift 21. In this side view you can see the in Insert direction A in the rest position extending away from each other Spring arms 12 and 14 of the spring means 10 and 11.
- the spring bars 13 and 15 are arranged to run towards each other, so opposite the spring arms 12 and 14 are again bent so that there is an opposite course.
- the Spring bars 13 and 15 protrude the contact tongues 5 and 6 towards the front and run essentially at rest parallel to each other.
- Figure 4b now shows the initial insertion the pin 21 between the contact tongues 5 and 6.
- the pin is in cross section rectangular pencil with rounded corners and with dimensions of approx. 4 mm x 5 mm.
- Figure 4b shows an insertion about 3 mm deep between the reeds, which spread apart.
- EP-A 0 783 776 is inserted only between the reeds 5 and 6, i.e.
- Figure 4d shows the end position at which the pin approx. 10 mm deep into the contact spring arrangement 1 is inserted.
- the spring bars 13 and 15 are thereby by the pin 21 in a no longer facing each other, or parallel, situation forced by what is appropriate Bend the contact tongues 5 and 6 to the webs 13 and 15 a strong pressing of the tongues 5 and 6 the pin 7 and thus a high contact force gives what is desirable when the pen is fully inserted. It it can thus be seen that the contact area only from tongues 5 and 6 and webs 13 and 15 is formed, the spring means can be chosen so that there is an easy insertion together with a high one Contact force in the end position in a simple way can be realized.
- Figure 5 shows the open housing 24 one Socket for mains voltage, in which three contact spring arrangements 1, 1 'and 1 "are arranged in the housing.
- the upper end of the housing which is not shown the receiving area for the contact spring arrangements covers and only openings for the pens above of the respective contact tongues.
- openings 25 are provided through which the connecting conductor for the contact spring arrangements for the connection terminals 20 are feasible.
