Problems solved by technology

This contact structure requires that one contact be inserted deeply into the other, which is disadvantageous in many applications
Also, insertion of one contact deeply into another may change the characteristic impedance along those contacts and cause loss

Embodiment Construction

[0019] figure 2 Shown is a connector system 10 comprising first and second coaxial connectors 12, 14 arranged along the front (F) rear (R) On the axis 16 extending in the direction. Each connector is symmetrical about an axis. The first connector 12 includes a movable center or inner contact 20 and a movable outer contact 22 . The inner and outer contacts are biased forward by separate helical coil compression springs 24,26. Two compression springs extend around the axis and thus avoid sudden changes in the characteristic impedance. A central stop 27 limits the forward movement of the inner contacts and an outer stop 28 which may abut against the rear end 29 of the clip limits the forward movement of the outer contacts. The second connector 14 has stationary inner and outer contacts 30,32 whose rear ends form contact pads 34,36. The contact pads 34, 36 are preferably flush with each other, and when the front ends 37, 38 of the movable contacts are engaged with the contac...

Abstract

The present invention discloses a connector system which includes matched first and second mateable connectors (12, 14) with coaxial contacts, wherein the first connector has movable center and outer contacts (20, 22) that are each biased forward by a separate spring (24, 26) to engage stationary contact pads (34, 36) of the mating second connector. A stationary tubular insulator (100) surrounds much of the movable center contact, and a stationary sheet metal shield (102) lies around the tubular insulator and within the outer contact. The front end of the movable outer contact forms an internal flange (80) with a hole (84) that allows the front end of the movable center contact to pass through. The shielded front-end has an internal flange (112) that lies between the front end of the tubular insulator and the movable outer contact internal flange, to maintain a constant impedance through out the first connector.

Description

technical field [0001] The invention relates to a double spring probe coaxial contact system. Background technique [0002] Connectors typically include coaxial contacts in order to transmit high frequency signals (eg, over 1 MHz). One design uses longer pin and socket contacts in order to ensure good electrical engagement between mating contacts. This contact structure requires that one contact be inserted deeply into the other, which is disadvantageous in many applications. Also, insertion of one contact deeply into another may change the characteristic impedance along those contacts and cause losses. [0003] It would be valuable to have a contact structure for a connector that includes at least one set of coaxial contacts that can be mated by only a short movement of one contact into the other and that can be tightly controlled characteristic impedance along the connector. Contents of the invention [0004] According to one embodiment of the present invention, ther...
