DE202017004941U1 - Scalable contact - Google Patents

Abstract

Scalable contact according to the description, characterized in that all the dimensions which are important for the production of the contact can be measured from the drawing page 8 and multiplied by the factor 0.35, which give manufacturing dimensions, if they correspond to '+/- 0, 05 mm tolerated. That gives a contact with about 60 amps with 0.1 mOhm.

Description

STATE OF THE ART

The electrical contacts in connectors are socket contacts with spring action and inserted pin or blade contacts.

There are also contact sockets without spring action and pin contacts with spring action. Both systems need minimum lengths of the springs to have the best effect. These techniques have been in use since the 19th century. There are also spring washers which enhance the spring action of the contact sockets.

DESCRIPTION OF THE INVENTION

Due to the rapidly growing energy production and the simultaneously growing energy demand, today new, different acting electrical contacts are needed, which have higher performance and require less material.

The invention described below is an electrical contact which has already been described in AZ 10 2017 007 091.1. It can be scaled from a silver ring on the contact pin 2 is mounted. The contact pin 2 has a groove in which the silver ring lies.

The functions jack, ring, or pin and the respective counterpart can be divided into 3 parts - socket - ring - pin, which work both together and independently.

The contact socket we thereby much easier to manufacture and can be made of any conductive material, such as copper, aluminum, brass, u. a. be prepared because no resilient function is needed.

The contact consists of a Cu ring 3 , or Ag and is from the contact pin 2 in the socket 1 pressed, like shows.

The pressure of 15 N, or higher, can be arbitrarily dimensioned by the dimensions of the ring wire. The ring material may be Ag, Cu, or other electrically conductive material. With Cu pin / socket and Ag ring electrical conductivity K 60 is achieved, which is unique for connectors and therefore patentable.

The axial movement of the contact pin 2 may be due to the conical pitch in the contact socket 1 be dimensioned

This path gives an adjustable compressive force of 10 to 250 N, which is sufficient to achieve the optimum contact resistance of less than 0.1 mOhm.

The invention describes the technique of how the ring contact can be mounted to achieve high contact force and thereby low contact resistance.

The contact pin 2 may be of Cu, or other conductive metal.

The contact pin 2 with the ring contact 3 will be in a contact socket 1 , inserted without insertion force. The contact force is created by locking the connector, such as shows.

These three parts, contact pin 2 Contact socket 1 and ring 3 can be with Ag, Au, or other materials that improve the function.

The ring contact 3 will be on the contact pin 2 mounted or can also be in the contact socket 1 be mounted.

The contact pin 2 and the contact socket 1 can be connected to the cables with a solder connection, crimp connection or other connection techniques.

Since the plug and pull forces are zero = 0, high-pole connectors can be produced, the number of poles is limited only by the applied closing force of the connector housing.

This creates contact between everyone 3 share 1 to 3 and 3 to 2 ,

The most important advantage over today's contacts with slotted bushings and friction is the ring 3 , If this is exactly guided, a small insertion distance of less than 0.2 mm can be achieved.

All three parts, contact socket 1 , Contact pin 2 and ring 3 have an electrical function and are therefore made of conductive material.

The contact pin 2 has a cone, the contact ring 3 in the contact socket 1 and their cone pushes. The cones can be the same or different, which is the way of the contact ring 3 certainly.

The travel is to be dimensioned exactly, whereby the spring force and the contact resistance are exactly adjustable.

The contact ring system can be produced with very low internal friction and very small paths.

For contacts with pin diameter> 10 mm and spring wire diameter> 1 mm may be the way of the ring 3 be increased radially.

The path of the ring contacts also determines the closure path of the bayonet or screw cap.

The contact ring system is scalable in the way that you can get out of the For example, take a measure of the lead wire 3.5 mm and set this dimension with the drawing 10 mm in the ratio 3.5: 10 = 0.35 and then calculate all important measures with a factor of 0.35 and tolerated with +/- 0.05 ,

This gives you a contact that works that way, the original contact, but with reduced power.
