Cassette connector

Claim 2

In combination: a cassette including a package having two major opposing walls and a bottom wall through which a plurality of electrical terminals are exteriorly accessible; and an electrical connector in secured receipt of said cassette, said connector including a housing having a cavity defined by a wider access opening than the bottom portion of said cavity, a plurality of spring contacts disposed in said housing cavity adjacent a bottom surface of said cavity and in electrical engagement with said cassette terminals, and engaging means maintaining said cassette and connector in retentive engagement, said engagement means including cooperative latching means on the cassette and connector housing that permits oblique insertion of said cassette into said housing in a first direction and retains said cassette in said housing in response to rotational movement of said cassette within said cavity, said terminals sliding on said spring contacts during said rotational movement of said cassette, said latching means comprising a ridge portion on said cassette and a recess portion of said housing cavity in receipt of said ridge portion, said cassette having opposing side walls connecting said two major opposing walls, and wherein said ridge portion includes a generally L-shaped projection extending outwardly from at least one of said side walls, a ridge for engagement with said housing within said recess being disposed on said L-shaped projection, said ridge being disposed adjacent the top portion of said L-shaped projection, said recess being sized to accommodate the foot portion of said L-shaped projection during insertion of said cassette into said housing cavity.

Claim 3

An electrical connector assembly comprising: a cassette including a package having a plurality of exteriorly accessible electrical terminals and including a generally L-shaped projection extending outwardly from a portion of said package, a ridge being disposed adjacent the top portion of said L-shaped projection; and an electrical connector including a housing for secured receipt of said cassette, said housing having a cavity therein for receipt of said cassette and a plurality of electrical spring contacts disposed in said housing cavity and arranged therein to engage the terminals of said cassette upon insertion of said cassette therein, said housing having a recess (23') in an inside wall defining said cavity, said recess being sized to receivingly accommodate the foot portion of said L-shaped projection, said housing having a latching member for latchingly engaging said ridge on said L-shaped projection when said cassette is inserted on said connector.

Claim 4

An electrical connector assembly comprising: a cassette including a package having a plurality of exteriorly accessible electrical terminals and including a generally L-shaped projection extending outwardly from a portion of said package, a ridge being disposed adjacent the top portion of said L-shaped projection; and an electrical connector including a housing for secured receipt of said cassette, said housing having a cavity therein for receipt of said cassette and a plurality of electrical spring contacts disposed in said housing cavity and arranged therein to engage the terminals of said cassette upon insertion of said cassette therein, said housing having a recess (23') in an inside wall defining said cavity, said recess being sized to receivingly accommodate the foot portion of said L-shaped projection, said housing having a latching member for latchingly engaging said ridge on said L-shaped projection when said cassette is inserted on said connector.

Claim 5

An electrical connector assembly as claimed in claim 2, wherein said cavity has an opening which is gradually increased in dimension from the bottom of the cavity.

Claim 6

An electrical connector assembly as claimed in claim 2, wherein said cavity is shaped to receive said cassette obliquely into said cavity and wherein said latching engagement is effected upon movement of said cassette into a position generally perpendicular to said cavity.

Claim 7

An electrical connector assembly as claimed in claim 4, wherein said recess comprises a guide groove (23'A) for inserting the cassette obliquely into said cavity and a mate groove (23'B) for latching said ridge upon movement of said cassette into a position generally perpendicular to said cavity.

Claim 8

An electrical connector assembly comprising: a cassette including a package having two major substantially parallel opposing walls spaced by a given spacing, a bottom wall extending transversely between said two major walls and a plurality of electrical terminals contained within said package that are exteriorly accessible through said bottom wall, and a latching element on said package; and an electrical connector for secured receipt of said cassette, said connector including a housing, a back surface, a front surface spaced from said back surface and a bottom surface, said back, front and bottom surfaces defining a cavity for receipt of said cassette, said front surface and said back surface converging toward each other and defining thereby an opening at the upper portion of said cavity that is wider than the given spacing of said cassette such that cassette may be inserted obliquely into said housing and defining at the lower portion of said cavity an opening that is narrower than said given spacing of said cassette such that the opposing major walls of said cassette will strike the front surface and back surface of said connector housing adjacent the bottom of said cavity, said connector further including a plurality of electrical spring contacts supported by said housing and extending into said cavity adjacent said housing bottom surface, a portion of each of said contacts lying upwardly of said narrower opening of said cavity, said contacts being arranged to respectively deflectably engage the terminals of said cassette when said cassette major walls strike said front and back housing surfaces, said housing including a latching member adapted to cooperatively latchingly engage said latching element on said cassette upon rotation of said cassette within said housing cavity on said electrical contacts from said initial oblique insertion position to a latching position.

Claim 9

An electrical connector assembly comprising: a cassette including a package having two major substantially parallel opposing walls spaced by a given spacing, a bottom wall extending transversely between said two major walls and a plurality of electrical terminals contained within said package that are exteriorly accessible through said bottom wall, and a latching element on said package; and an electrical connector for secured receipt of said cassette, said connector including a housing, a back surface, a front surface spaced from said back surface and a bottom surface, said back, front and bottom surfaces defining a cavity for receipt of said cassette, said front surface and said back surface converging toward each other and defining thereby an opening at the upper portion of said cavity that is wider than the given spacing of said cassette such that cassette may be inserted obliquely into said housing and defining at the lower portion of said cavity an opening that is narrower than said given spacing of said cassette such that the opposing major walls of said cassette will strike the front surface and back surface of said connector housing adjacent the bottom of said cavity, said connector further including a plurality of electrical spring contacts supported by said housing and extending into said cavity adjacent said housing bottom surface, a portion of each of said contacts lying upwardly of said narrower opening of said cavity, said contacts being arranged to respectively deflectably engage the terminals of said cassette when said cassette major walls strike said front and back housing surfaces, said housing including a latching member adapted to cooperatively latchingly engage said latching element on said cassette upon rotation of said cassette within said housing cavity on said electrical contacts from said initial oblique insertion position to a latching position.

Claim 10

An electrical connector assembly according to claim 6, wherein said back surface is substantially perpendicular to said bottom surface and said front surface is oblique relative to said bottom surface.

Claim 11

An electrical connector assembly according to claim 7, wherein said electrical contacts project cantileveredly into said cavity, said contacts being supported by said back surface.
