Abstract
Abstract A multi-conductor electrical connector for mounting on a printed circuit board which includes two rows of staggered insertion holes. The connector includes a housing having an elongate cavity. A contact strip is formed with a continuous carrier and laterally extending contacts gang-mountable in the elongate cavity of the housing. Each contact includes a conductor receptacle positionable in the cavity, and a pair of laterally spaced terminal tails projecting through the housing from the cavity. The terminal tails are independently severable whereby a terminal tail of any contact can be inserted into a hole in either row of staggered insertion holes in the printed circuit board. The contact receptacle is formed by an anvil portion and a spring finger portion. The terminal tails are stamped and formed out of the anvil portion and the spring finger portion of the contact.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
169 words
A multiple-conductor electrical connector adapted for low insertion and high retention forces on a conductor, comprising: an insulating housing having a cavity; and a stamped and formed sheet metal contact mounted in the cavity and including an anvil portion at one side of the cavity and a spring finger portion at an opposite side of the cavity, the spring finger portion being inclined in a manner whereby a conductor can be inserted into the cavity between the anvil portion and the spring finger portion with low insertion force and the spring finger portion opposes withdrawal of the conductor from the cavity, the contact having a pair of terminal tails projecting through the housing from said opposite sides of the cavity, the terminal tails being independently severable whereby a selected one of the tails can be disposed in a selected one of a pair of spaced contact lines on the housing and wherein one of said terminal tails is stamped and formed out of the anvil portion of the contact.
Claim 2
Dependent Claim
169 words
A multiple-conductor electrical connector adapted for low insertion and high retention forces on a conductor, comprising: an insulating housing having a cavity; and a stamped and formed sheet metal contact mounted in the cavity and including an anvil portion at one side of the cavity and a spring finger portion at an opposite side of the cavity, the spring finger portion being inclined in a manner whereby a conductor can be inserted into the cavity between the anvil portion and the spring finger portion with low insertion force and the spring finger portion opposes withdrawal of the conductor from the cavity, the contact having a pair of terminal tails projecting through the housing from said opposite sides of the cavity, the terminal tails being independently severable whereby a selected one of the tails can be disposed in a selected one of a pair of spaced contact lines on the housing and wherein one of said terminal tails is stamped and formed out of the anvil portion of the contact.
Claim 3
Dependent Claim
25 words
The electrical connector of claim 1 wherein the other of said terminal tails is stamped and formed out of the spring finger of the contact.
Claim 4
Dependent Claim
41 words
The electrical connector of claim 1, including a cover for at least partially closing said cavity, the cover being movably mounted on the housing for movement against the spring finger portion of the contact to release the conductor for easy withdrawal.
Claim 5
Dependent Claim
112 words
For use in an electrical connector for mounting on a printed circuit board which includes two rows of staggered insertion holes, the connector including an insulating housing having elongate cavity means: a contact strip having a continuous carrier with laterally extending stamped and formed contacts gang-mountable in the elongate cavity means of the housing, each contact including conductor receptacle means positionable in the cavity means and a pair of laterally spaced terminal tails projecting through the housing from the cavity, and the terminal tails being independently severable whereby a terminal tail of any contact can be inserted into a hole in either row of staggered insertion holes in the printed circuit board.
Claim 6
Dependent Claim
112 words
For use in an electrical connector for mounting on a printed circuit board which includes two rows of staggered insertion holes, the connector including an insulating housing having elongate cavity means: a contact strip having a continuous carrier with laterally extending stamped and formed contacts gang-mountable in the elongate cavity means of the housing, each contact including conductor receptacle means positionable in the cavity means and a pair of laterally spaced terminal tails projecting through the housing from the cavity, and the terminal tails being independently severable whereby a terminal tail of any contact can be inserted into a hole in either row of staggered insertion holes in the printed circuit board.
Claim 7
Dependent Claim
51 words
The contact strip of claim 4, in combination with a cover movably mounted on the housing for movement into engagement with the spring finger contact portion to move the spring finger contact portion out of engagement with the conductor and thereby allow for ready withdrawal of the conductor from the connector.
Claim 8
Dependent Claim
25 words
The contact strip of claim 4 wherein said receptacle includes an anvil contact portion and a spring finger contact portion for receiving a conductor therebetween.
Claim 9
Dependent Claim
