Abstract
ABSTRACT
An electrical connector comprising an insulating housing formed with a plug-receiving socket and a metal contact mounted in the housing with a spring contact arm projecting along the socket from an insertion end, a root end of the arm being adjacent one socket wall in which the separation of the arm and the wall increases towards the free end of the arm such that insertion of the plug into the socket causes a position of engagement between the arm and the wall to move progressively in the insertion direction. Preferably, the wall is planar and the arm bows away from the wall towards its free end.

Description
1C~6i4Z8 The invention relates to electrical connectors.
According to the invention an electrical connector comprises a cantilever spring contact arm supported with one end adjacent one planar side of a housing wall and curving away from the wall towards a free end such that movement of a mating contact post parallel to the wall from the one end towards the free end in contact with the spring causes the spring to engage the wall at a position which provides the ~ulcrum of the spring and which moves progressively towards the free end.
Thus, the progressive movement of the fulcrum of the arm causes a progressive increase in the insertion force.
Specific examples of the invention will now be descrihed ~ith reference to the accompanying drawings in which:-Figure 1 is a perspective view of a first contact;
Figure 2 is a schematic view of a first connector comprising the contact with a post at a first stage of in-sertion;
Figure 3 is a view similar to Figure 2 with the post at a further stage of insertion;
Figure 4 is a perspective view of a second contact;
Figure 5 is a cross-sectional elevation of the housing containing the contact of Figure 4; and, Figure 6 is a cross-sectional vie~ of part of the connector taken along line 6-6 of Figure 5.
The contact of Figure 1 is stamped and formed from

The contact of Figure 1 is stamped and formed from
- 2 -1~61428 8610 sheet metal 5tvck and comprises a pair of parallel plates 11 spaced apar1: in opposed relatlon and ha~ing aligned conductor-receiving slots 12 opening out into upper ends -of the plates which are connected by spaced straps i3.
A supporting foot 14 extends transversely from a lower end of one plate between the plates and assists in maintaining a predetermined separation between the plates.
A strip 15 extends transversely from a lower end of the other plate away from both plates and is reversely bent defining a contact spring arm 16 which bows progressively away from the strip 15 towards a free end.
The contact is mounted in a connector housing having parallel planar walls 17 and 18 defining between them a post-receiving socket 19 with the wall 17 received in the bend and the spring arm 16 projecting along the socket from an insertion end.
An insulated wire can be conne~ted to the plates 11 by forcing it transversely of its axis in'o the slots through the open ends so that the edges of the slots penetrate the insulation and contact the core.
Progressive insertion of a contact post 20 into the socket causes the spring arm 16 to flex awa~ from the wall 18 and the position of engagement with wall 17, i.e. the fulcrum of the arm, to move progressively in the insertion direction. The contact post engages the arm 16 at an early stage of insertion so that the arm is progressivel~ deflected o~er a substant~al insertion ~.
r 3 ~(~61428 distance. The conllector, thereore, permits a low initial i.nsertion force which increases progressively during insertion to a max~mum.
I~ the second example a pair of opposed spring arms 21 bow towards each other as they progress towards their free ends and axe located spaced apart at root ends by a channel-section web 22 which extends transversely from a slotted plate structuxe similar to that of the fixst example.
The contact is mounted in a connectox housing 24 with one housing wall received in the web and the arms projected into a post,-receiving socket 25. Tangs 26 are provided on the web to aid retention of the contact in the housing. On ~nsertion o a contact post 27 into the socket fxom the root ends of the arms towards their free ends a moving fulcrum effect for each arm. simi~ax to that of the first example is pxoduced.

PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. An electrical connector comprising a cantilever spring contact arm supported with one end adjacent one planar side of a housing wall and curving away from the wall towards a free end such that movement of a mating contact post parallel to the wall from the one end towards the free end in contact with the spring causes the spring to engage the wall at a position which provides the fulcrum of the spring, and which moves progressively to-wards the free end.
2. An electrical connector according to claim 1 in which the contact includes a second similar arm, the two arms extending in opposed relation from opposite walls of a channel-section web similarly supported adjacent opposed walls of a socket housing.
3. An electrical connector according to claim 1 in which the arm is reversely bent at a root end and one end of the wall is located in the bend, the root end being integrally joined to a metal plate having a wire-receiving slot which upstands from a side of the wall remote from the arm.
4. An electrical connector according to claim 2 in which the base of the web is integrally joined to a metal plate having a wire-receiving slot upstanding from a side of an adjacent socket wall remote from the arm.
