Abstract
Abstract An electrical contact terminal (2) of the type contained in a connector housing (46) comprises a yoke portion (4) having extending therefrom, a contact arm (6) and a spring arm (8). The contact arm (6) has an electrical contact portion (34) on one side thereof and a bearing portion (32) on the other side which bears against a bearing portion (44) on the spring arm (8). When the contact arm (6) is flexed toward the spring arm (8) by a mating part, such as a circuit board (24), the contact force is developed in the spring arm (8) and the contact arm (6) serves primarily as a conductor. The terminal (2) and the contact arm 6 serves primarily as a conductor. The terminal 2 is produced by stamping sheet metal without subsequent bending, so that all parts of the terminal lie in the plane of the sheet metal from which it was produced. Terminals of the type described are used in electrical connectors for printed circuit boards which are also described.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
An electrical terminal (2) of the type which has substantially all of its parts in a flat plane, the plane being defined by the thickness of the metal of the terminal (2), the terminal having a contact arm (6) which is flexible in the plane of the terminal, the contact arm having a fixed end (26), a portion (34) of the edge of the contact arm which is spaced from the fixed end (26) being a contact portion of 'the terminal, 'the terminal (2) being characterized in that: the terminal has a yoke section (4), the fixed end (26) of the contact arm (6) being on the yoke section, a spring arm (8) extends from the yoke section, the spring arm being beside the contact arm (6), the contact arm (6) and the spring arm (8) have opposed bearing edge portions (32, 34) which are against each other when the contact arm (6) is flexed towards the spring arm (8) whereby the contact force developed in the terminal is produced by the spring arm.
Claim 2
Dependent Claim
174 words
An electrical terminal (2) of the type which has substantially all of its parts in a flat plane, the plane being defined by the thickness of the metal of the terminal (2), the terminal having a contact arm (6) which is flexible in the plane of the terminal, the contact arm having a fixed end (26), a portion (34) of the edge of the contact arm which is spaced from the fixed end (26) being a contact portion of 'the terminal, 'the terminal (2) being characterized in that: the terminal has a yoke section (4), the fixed end (26) of the contact arm (6) being on the yoke section, a spring arm (8) extends from the yoke section, the spring arm being beside the contact arm (6), the contact arm (6) and the spring arm (8) have opposed bearing edge portions (32, 34) which are against each other when the contact arm (6) is flexed towards the spring arm (8) whereby the contact force developed in the terminal is produced by the spring arm.
Claim 3
Dependent Claim
18 words
An electrical terminal (2) as set forth in claim 1, the terminal being a stamped sheet metal member.
Claim 4
Dependent Claim
32 words
An electrical terminal (2) as set forth in claim 2 having an integral solder post (10) extending from the yoke (4) section for soldering to a conductor on a circuit board (14).
Claim 5
Dependent Claim
38 words
An electrical terminal (2) as set forth in claim 3, the contact arm (6) having an extension (30) which extends towards the spring arm (8), the bcaring edge portion (32) of the contact arm being on the extension.
Claim 6
Dependent Claim
51 words
An electrical terminal (2) as set forth in either of claims 1 or 4, the spring arm (8) extending from the yoke portion (4) past the free end (28) of the contact arm and then extending in a reverse direction (40, 41) back towards the free end of the contact arm.
Claim 7
Dependent Claim
94 words
An electrical terminal (2) as set forth in claim 5, the terminal being contained in a terminal- receiving cavity (48) of an electrical connector housing (46), the cavity having-an opening (52) therein adjacent to the free end (28) of the contact arm (6), a portion of the free end (28) of the contact arm including the contact portion (34) extending through the opening (52) whereby upon placement of a circuit board (24) against the housing (46), the contact portion (34)of the contact arm (6) will contact a conductor (20) on the circuit board (24).
Claim 8
Dependent Claim
30 words
An electrical terminal (2) contained in a housing (46) as set forth in claim 6, the housing (46) having a plurality of identical terminals (2) therein in side-by-side spaced-apart relationship.
Claim 9
Dependent Claim
54 words
An electrical terminal (2) contained in a housing (46) as set forth in claim 7, the housing (46) having a clamp (72) for clamping a circuit board (24) against the housing (46) thereby to engage conductors (20) on the circuit board (24) with the contact portions (34) of contact terminals (2) in the housing.
Claim 10
Dependent Claim
67 words
An electrical contact terminal (2) contained in a housing (46) having a clamp (72) as set forth in claim 8, the clamp being a stamped and formed sheet metal frame (56) having a channel-shaped cross-section, the housing (46) being between the sidewalls (58, 62) of the channel-shaped member (56) and against one of the sidewalls (58), a clamping member (70) beinf mounted on the other sidewall (62).
Claim 11
Dependent Claim
40 words
An electrical contact terminal (2) contained in a housing (46) having a clamp (72) as set forth in claim 9, the clamping member (70) being a shaft having a plurality of spaced-apart circular cams (72) eccentrically mounted on the shaft.
