Abstract
Abstract A cord adapter has a plurality of male plug stabs to establish electrical contact with a cooperating contact in a plug receptacle or jack. Each plug stab is comprised of a post extending upwardly from the base of the adapter and receiving a blade of a contact with the end of the blade staked to the post at the top thereof. The vertical portion of the blade faces laterally outward. Spade terminals of the cord are adapted to be received in spade terminal receptacles within the base and engage additional blades of the contacts. The spades are bent at right angles so that their shanks are received in troughs of the adapter''s contact mounts to keep individual spades from touching other spades and to present a low vertical profile in the cord adapter. The cord itself is secured within the adapter either by a T-type connection or a fixed loop connection. A catch for a latch extends from the base on the plug stab side for latching engagement in the female plug receptacle.

Claim 1
Independent Claim
307 words
A cord adapter for a cord having a plurality of conductors, the adapter being for connecting the conductors of the cord with contacts of a female plug receptacle, the cord adapter comprising: a. a base; b. a first series of at least two posts integrally connected to the base and extending upright therefrom, the first posts being equidistant from and to one side of the longitudinal centerline of the base; c. a second series of posts corresponding in number to the number of posts in the first series, the second series of posts being integrally connected to the base and extending upright therefrom, the second posts being equidistant from and to one side of the longitudinal centerline on the side opposite thereof from the first series of posts; d. posts of the first and second series being paired with each pair of such posts being bisected by an imaginary plane perpendicular to the longitudinal centerline; e. a first contact blade associated with each of the posts, each first contact blade being rigidly secured to its associated post, each pair of posts having their first contact blades facing in the same direction relative to the longitudinal centerline; f. a pocket in the base associated with each of the posts, each of the pockets being sized to receive a spade terminal attached to one of the conductors of the cord; g. a second contact blade associated with each of the posts, each second contact blade being in the pocket associated with the same post for engagement by the blades of a spade terminal, each second contact blade being integral with the first contact blade associated with the same post; and h. a trough into each of the pockets for receiving the shank of a spade terminal when the spade terminal is bent at a right angle to its blades.

Claim 4
Dependent Claim
88 words
The cord adapter claimed in claim 1 wherein: a. each pocket includes: i. vertical walls and a horizontal base, the walls being generally parallel with the posts and the horizontal base being generally perpendicular thereto; ii. a pair of opposed slots in opposed of the vertical walls; iii. a slot in the horizontal base; and b. each second contact blade includes: i. end tab portions received in the opposed slots in the vertical walls; and ii. a generally horizontal knee section in the slot of the horizontal base.
Claim 5
Dependent Claim
62 words
The cord adapter claimed in claim 3 wherein: a. each post has a recess at its exposed end; and b. each first contact blade is staked within the recess, whereby the integrated first and second contact blades are fixed in position parallel to their associated post by the knee of the second contAct blade and the staking of the first contact blade.
Claim 6
Dependent Claim
284 words
A cord adapter for adapting a multiconductor cord for plug-in engagement with a female plug receptacle comprising: a. a base; b. a first row of at least two upstanding posts integrally connected with the base equidistant from a longitudinal centerline through the adapter, each of the posts having a rectangular cross section; c. a second row of upstanding posts integrally connected to the base equidistant from the longitudinal centerline of the adapter with the distance to the second series of posts from the longitudinal centerline being the same as from the longitudinal centerline to the first series of posts, each of the second row of posts having a ractangular cross section, and opposed pairs of the first and second series of posts across the longitudinal centerline being bisected by an imaginary plane perpendicular to the longitudinal centerline; d. a first bank of pockets in the base, the pockets corresponding in number to the number of posts in the first row of posts; e. a second bank of pockets in the base with the pockets of the second bank corresponding in number to the posts in the second row of posts; f. contact means in each of the pockets for direct intimate contact with a space terminal secured to a conductor of the cord, each contact means having a blade element extending along and in engagement with a lateral side of the post associated with its pocket and being rigidly secured thereto by being staked within a recess at the exposed end of the post; and g. each blade in each opposed pair of posts facing in the same direction relative to the longitudinal centerline as the other blade in the opposed pair of posts.
