Abstract
Abstract A hermaphroditic electrical connector comprising a pair of substantially identical body members releasably secured together to electrically connect plural electrical contacts of one member to respective electrical contacts of the other member and for maintaining such electrical connections while enabling the two connector members to be pivoted with respect to each other about a longitudinal axis through a predetermined angular range. The means for securing the two connector members together comprise a post and a recess on each body member aligned with the longitudinal axis to enable the post of one member to be readily snap-fit within the recess of the other member. Each of the two body members includes spaced-apart ribs which, when the two members are connected together, are interleaved to define plural internal spaces. Each space houses a pair of engaging contacts and is generally isolated from the ambient atmosphere. Each contact includes a post section, an anchoring section, and cantilever sections of the contacts serve as the means for effecting the electrical connection between them. To that end, each cantilever section includes a generally planar engagement surface disposed generally perpendicularly to the longitudinal axis of the connector and contiguous therewith. When the two body members are brought together, their cantilever sections deflect somewhat and the engagement surfaces of the contacts make good electrical connection with each other over a relatively large area irrespective of the angular orientation between the two body members.

Claim 4
Dependent Claim
65 words
The electrical connector of claim 2 wherein each of said cantilever sections is formed of a resilient material and configured to flex in a manner to ensure that the plane of the engagement surface of each contact of one member remains parallel to the plane of the engagement surface of the corresponding contact of the other member when the two body members are secured together.
Claim 5
Dependent Claim
20 words
The electrical connector of claim 3 wherein the plane of said engagement surfaces is essentially perpendicular to said longitudinal axis.
Claim 6
Dependent Claim
98 words
The electrical connector of claim 1 wherein said cantilever portion is formed from a strip of material and with said free end portion, engagement portion, and arm portion each being planar, but with the free end portion and said arm portion each extending at a slight acute angle to the plane of said engagement portion and with the width of said engagement portion and arm portion each being the same while the width of said free end portion tapers toward its free end and with the length of said arm portion being longer than said free end portion.
