Abstract
Description
- Zero insertion force electrical connector.
- We have described in EP-Al-78300558.0, a zero insertion force circuit board edge electrical connector, comprising an insulating housing having an elongate opening for receiving a circuit board along a board insertion path; at least one row of electrical terminals positioned beside the opening and extending in the longitudinal direction thereof, each terminal having a resilient contact portion for engaging the circuit board when such has been inserted into the opening along the insertion path; a groove formed in the bottom of the opening and extending longitudinally thereof; an elongate cam mounted for rotation about its longitudinal axis in the groove and extending longitudinally thereof; and a cam follower having a first surface engaging the cam, the cam follower being displaceable normally of the base of the groove by rotation of the cam, to cause the cam follower to move between a first position in which it displaces the contact portions from the insertion path and a second position in which the cam follower is retracted to allow the contact portions to intersect the insertion path.
- The use of a rotary cam as opposed to a linear action cam has the advantages that no space is required to accommodate reciprocating movement of the cam and that the cam can be of very simple "construction, being for example of oblong or of substantially eliptical, cross-section.
- However, in this known connector, the cam follower is returned from its first to its second position by virtue of the resilience of the contact portions of the terminals, which resilience also serves to maintain the cam follower in its second position. It has been found, that their exercise of this return function tends to cause the contact portions to loose resilience with the result that the cam follower, after an extended period of use of the connector, can no longer be fully returned to its second position so that the connector becomes inoperative, or the cam follower is readily displaced from its second position. Especially where the connector is subjected to vibration whilst in use or is mounted so that the return of the cam follower is not assisted by gravity, this latter disadvantage will result in intermittent impairment of the integrity of the electrical connections between the contact portions and the conductors of the circuit board.
- According to the present invention therefore a connector as defined in the first paragraph of this specification is characterised in that the cam follower has a second surface spaced from the first surface towards the base of the groove and which is engageable by the cam, as the cam is rotated to cause the cam follower to move from its first to its second position, so that the cam positively drives the cam follower to its second position, in which "position the second surface engages the side of the cam nearest to the base of the groove so that the cam follower is secured in its second position by the cam, against unintended movement.
- Although DE-A-2,707,122 discloses a zero insertion force electrical connector, in which a cam follower acting upon the contact portions of the terminals of the connector is positively driven by means of a cam, the cam is a linear action cam, and the cam follower could not be positively driven by means of a rotary cam.
- US-A-3,596,230, US-A-3,899,234, US-A-4,047,782 and US-A-4,069,403 are also representative of the curront general state of the art.
- For a better understanding of the invention an embodiment thereof will now be described by way of example with reference to the accompanying drawings in which:-
- Figure 1 is a perspective sectional view of a zero insertion force circuit board edge electrical connector;
- Figure 2 is a longitudinal, vertical sectional view through an end portion of the connector;
- Figure 3 is an enlarged perspective, sectional view of a cam and a cam follower of the connector; and
- Figures 4 to 6 are cross-sectional views of the connector illustrating the operation thereof.
- The connector comprises an
insulating housing 10, acam 12, acam follower 14 and a plurality ofelectrical terminals 16. - The
housing 10 defines an elongatecentral opening 18 for receiving an edge portion of a circuit board 20 (Figure 1) along a board insertion path A, a row ofspacer members 22 on each side of the opening 18 defining recesses 24 each receiving aterminal 16 extending through apassage 26 in thebase 27 of thehousing 10, which passage communicates with the recess 24. - The opening 18 communicates with a
groove 28 formed in thebase 27, which defines the bottom of theopening 18, thegroove 28 extending longitudinally thereof. Thegroove 28 receives thecam 12 for free rotation therein. - At each end thereof the
housing 10 has a mounting lug 30 (only one is shown) with ascrew hole 32. - The cam follower 14 (best seen in Figure 3), which is channel-shaped, comprises a
base 34 having .parallel side walls base 34, awall 40 extending from a flat,cam engagement surface 35 of thebase 34, in alignment with, and in the opposite direction to, theside wall 36 and terminating in an inwardly directedflange 42 having a flat,inner abutment surface 43 parallel to, and overlapping thebase 34. Thebase 29 of thegroove 28 has therein a longitudinal recess 44 dimensioned to receive theflange 42. - The
base 34 of thecam follower 14 is disposed in thegroove 28 so that thesurface 35 of thebase 34 is engaged by thecam 12, thewall 40 protruding into thegroove 28 beside thecam 12. - The
cam 12, which is elongate in the direction of thegroove 28 and which can be rotated from outside thehousing 10 as shown in Figure 2, is of elongate cross-section having parallelmajor sides 45 and convexminor sides 47. Thesurface 35 of thebase 34 is spaced from thesurface 43 of theflange 42 by a distance slightly exceeding that between the major sides -45 of thecam 12, theflange 42 ovsrlapping thebase 34 by a distance which does not exceed that between thesides 45. - The
terminals 16 are in the form of metal strips having loopedresilient contact portions 50 within the housing,free end portions 52 of thecontact portions 50 engaging chamfered outer sides of the free longitudinal edges of theside walls 36 .and 38 of thecam follower 14. The terminals have lockingtongues 54 on.post portions 56 thereof, which portions extend through thepassages 26, thetongues 54 serving to retain theterminals 16 in thehousing 10. - Figure 4 shows the
cam follower 14 in a first position in which it has been advanced normally of thebase 29 of thegroove 28, by thecam 12 so that theside walls contact portions 50, displacing them from the insertion path A, to allow entry of the board 20 into the opening 18 along such path, with substantially zero insertion force. So to advance thecam follower 14, thecam 12 was rotated in an anticlockwise (as seen in Figures 4 to 6) sense, to an extent limited by a stop 58 on the left hand (as seen in Figures 4 to 6) side of thegroove 28. - As the
cam 12 is rotated in the opposite sense, to retract theearn follower 14 in thegroove 28, normally of the base thereof, to a second position, so as to allow thecontact portions 50 to close so as to intersect the path A of the board 20 (which is not shown in Figures 4 to 6), onemajor side 45 of thecam 12 engages theflange 42, as shown in Figure 5, to drive thecam follower 14 positively towards the base of thegroove 28, until, as shown in Figure 6, theflange 42 is fully received in the recess 44 and themajor sides 45 of thecam 12 are in full surface to surface engagement withsurface 35 of theCam follower 14 and with thebase 29 of thegroove 28, respectively, one convex minor side of thecam 12 being received between thebase 34 and theflange 42. In the second position of thecam follower 14, thesurface 43 of theflange 42 engages theside 45 of thecam 12, nearest to thebase 29 of thegroove 28, as shown in Figure 6, so that thecam follower 14 is locked in its second position by thecam 12. - Since the
cam follower 14 is positively driven by thecam 12, in the event that thecontact portions 50 should loose resilience through use, they are nevertheless returned fully to their closed positions so .as to apply the required contact force against the conductors of the board 20, even in the event that the connector is mounted in an orientation in which the return of the cam follower is not assisted by gravity. - By virtue of the engagement of the
cam 12 against thesurface 43 of theflange 42, in the second position of thecam follower 14, thecam follower 14 is secured in its fully retracted position so that it cannot be unintentionally moved under the action of vibration for example, so as to impair the integrity of the electrical connections between thecontact portions 50 and the conductors of the circuit board 20. - For making connection to only one side of a circuit board, the connector may have only one row of terminals, one side of the cam follower being omitted and the base thereof on that side being arranged to slide against a blank wall of the housing.
