Definitions
- the invention relates to a contact device for a circuit board, with a resilient in the direction of actuation Contact and a counter contact.
- a generic contact device belongs to the state of the Technology. It is a common embodiment of how to Included in delivery of various manufacturers. These well-known commercially available soldering elements and miniature switching contacts for However, printed circuit boards either have a low over-stroke compensation or they are in their with a large overstroke Dimensions relatively large. The used here Contacts are complex and proportionate expensive.
- the invention has for its object a contact device of the above kind to create a big one Over-stroke compensation enables and a relatively small Installation space required.
- a contact device at the contact is designed as a flexible contact spring is that a first resilient leg with a Has contact surface and a second leg, which in Direction of actuation to the first leg resilient is compliant.
- the contact device designed in this way is also advantageous because it does not have a separate back pressure spring requires and a certain self-cleaning effect of Contact surfaces takes place, since this one when pressed experience small sliding movement.
- the contact spring one for Has soldering provided with the printed circuit board, on which a rag to relieve the solder joint on the PCB is sheared. This represents an inexpensive one Version in which no housing is required for fixing and is still sufficiently stable attachment.
- Reliable contacting of the contact surface with the Mating contact is achieved when the contact spring is in the area the contact surface is slotted, resulting in double contact leads.
- the contact spring 1 shows a contact spring 1 of a contact device according to the invention shown for printed circuit boards.
- the contact spring 1 is flexible with a first resilient Leg 2, with a contact surface 3 and with a second Leg 4 executed, the first in the direction of actuation Leg 2 is resiliently flexible.
- the contact spring 1 is slotted.
- the contact spring 1 has a Soldering area on which a tab 5 to relieve the solder joint is sheared on the circuit board.
- the contact spring 1 is made in one piece, the connection between the first 2 and the second leg 4 a relative has a large bending radius, which is the deflection of the second Leg 4 to the first leg 2 allows. To this A large overstroke can also be compensated for in this way.
- Figure 3 is a contact spring 1 for a horizontal installation position shown, the leg 2 almost perpendicular at the end is bent.
- FIG. 4 shows an embodiment according to the invention of an in a circuit board 6 contacted contact device in a lying position Installation position.
- This contact device differs differs from the previously described in accordance with FIG. 2 in particular by performing the counter contact, which here by two Contact pads 9 is realized. Otherwise corresponds to Structure and function of the contact device of the previous Embodiment described in the standing installation position according to FIG 2, so that to avoid repetitions on a repeated description is omitted here.
