Abstract
Abstract A single or multichannel electrical connector including a male connector having at least two prongs depending resiliently from a base, the prongs each having defined in the outer edge thereof a narrow notch with at least one of the notches having at least one conductor exposed at the bottom portions of the notch, the conductor extending internally through the prong, the prongs also having end portions with outwardly facing mutually inclined surfaces, the male connector being adapted to fit a female connector having an opening defined therethrough the configured to receive the prongs with the sides of the notches and the connector at the bottom of the notch engaging a protruding contact in a sidewall of the opening in the female connector such that the male connector may be inserted by engaging the opposed inclined planes of the prongs within the opening of the female connector, deforming the prongs towards one another to pass through the female connector thereupon again expanding the prongs to bring the contact of the female connector into engagement with the conductor of the male connector with the notches also engaging the front and back end walls of the female connector contact to secure the male connector therein. In the event more than one conductor is provided in a prong, the prong may be formed of independent sections.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
296 words
An electrical connector combination comprising: a male connector comprising a base portion, at least two substantially parallel resilient prongs extending from the base portion, a notch defined in the outer side portion of each prong, at least one electrical conductor positioned within each prong and exposed at the bottom portion of the notch defined in the prong, and outwardly facing inclined surfaces defined between the terminus of each prong and the notch defined therein, the inclined surfaces extending to the terminus of each prong and being in a diverging relationship from the termini of the prongs to the notches defined in the prongs; a female connector comprising a member having an opening with opposed sidewalls and of a depth greater than the width of the notches in the prongs defined therein and adapted to receive the prongs of the male connector, the width of the opening being greater than the greatest distance between the termini of the prongs, and at least one protruding electrical contact narrower than the width of the notches positioned on each internal sidewall of the opening and adapted to bear upon the exposed conductor of the male connector and fit between the sidewalls of a notch when the male connector is situated in the female connector; whereby, the male connector may be inserted into the female connector by elastically deforming the prongs together as the inclined surfaces bear upon the opening in the female connector upon insertion of the prongs into the opening defined in the female connector, and permitting the prongs to expand thereby positioning the male connector by means of the side edges of the notches bearing upon the electrical contacts in the female connector with the exposed conductors in the bottom of the notches also bearing upon the contacts.
Claim 2
Dependent Claim
296 words
An electrical connector combination comprising: a male connector comprising a base portion, at least two substantially parallel resilient prongs extending from the base portion, a notch defined in the outer side portion of each prong, at least one electrical conductor positioned within each prong and exposed at the bottom portion of the notch defined in the prong, and outwardly facing inclined surfaces defined between the terminus of each prong and the notch defined therein, the inclined surfaces extending to the terminus of each prong and being in a diverging relationship from the termini of the prongs to the notches defined in the prongs; a female connector comprising a member having an opening with opposed sidewalls and of a depth greater than the width of the notches in the prongs defined therein and adapted to receive the prongs of the male connector, the width of the opening being greater than the greatest distance between the termini of the prongs, and at least one protruding electrical contact narrower than the width of the notches positioned on each internal sidewall of the opening and adapted to bear upon the exposed conductor of the male connector and fit between the sidewalls of a notch when the male connector is situated in the female connector; whereby, the male connector may be inserted into the female connector by elastically deforming the prongs together as the inclined surfaces bear upon the opening in the female connector upon insertion of the prongs into the opening defined in the female connector, and permitting the prongs to expand thereby positioning the male connector by means of the side edges of the notches bearing upon the electrical contacts in the female connector with the exposed conductors in the bottom of the notches also bearing upon the contacts.
Claim 3
Dependent Claim
77 words
An electrical connector combination as set forth in claim 1 in which each conductor in the male connector is positioned flush with and extending across the bottom of the notch defined in the prong, and the contact of the female connector is in the form of a rectilinear electrical conductant material extending from the sidewall of the opening of the female conductor in a direction transverse to that in which the male connector enters the female connector.
Claim 4
Dependent Claim
73 words
An electrical connector combination as set forth in claim 1 in which one of the prongs is of a differing cross-section than the other of the prongs and the opening defined in the female connector is similarly different in cross-section on one side of the opening than on the other side, whereby the prongs of the male connector may be inserted into the opening defined in the female connector in only one orientation.
Claim 5
Dependent Claim
47 words
An electrical connector combination as set forth in claim 1 in which at least one prong of the male connector carries two conductors and the female connector has at least two independent contacts disposed in at least one sidewall of the opening defined in the female connector.
Claim 6
Dependent Claim
47 words
An electrical connector as set forth in claim 4 in which each prong carrying at least two conductors is longitudinally divided between the conductors, whereby each portion of the divided prong is adapted to independently urge each conductor against the associated electrical contact in the female connector.
