Abstract
Abstract A connector for printed circuit boards, particularly for flexible ones such as FPC or FFC, has an insulating housing (2) with a recess (7) opened up and base contacts (3) held in the housing at regular intervals and each having a resilient beam (14) and an arm (5) integral with the beam. Each beam has a conductive protrusion (17) in the recess, and each arm extending along the housing's top into the recess has a pivotal end (18) facing the protrusion. An insulated pressing cover (4) engaging with the pivotal ends is rotatable between its pressing position adjacent to and its releasing position remote from the protrusions. The pivotal ends (18) lock the cover then pushing the circuit board (30) against the resilient beams (14). The cover has cover contacts (20) rotatably engaging with the pivotal ends and corresponding to the base contacts (3), so that the pivotal ends, the cover contacts (20) and the printed circuit board (30) are electrically connected to each other at the pressing position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A connector for printed circuit boards, the connector comprising: an insulating housing having a recess opened upward and a top horizontal wall; a plurality of base contacts secured in the housing at regular intervals and each having a resilient beam and a contact arm formed integral therewith; each resilient beam having a conductive protrusion disposed in the recess, and each contact arm extending along the top horizontal wall into the recess and having a retaining portion facing the conductive protrusion; an insulated pressing cover engageable with the retaining portions and shiftable between a pressing position adjacent to the conductive protrusions and an releasing open position remote therefrom; the retaining portions capable of locking the pressing cover at its pressing position to push the printed circuit board or boards against the resilient beams; and a plurality of cover contacts disposed in the pressing cover and corresponding to the base contacts, so that the retaining portions, the cover contacts and the printed circuit board or boards are electrically connected to each other at the pressing position.
Claim 2
Dependent Claim
174 words
A connector for printed circuit boards, the connector comprising: an insulating housing having a recess opened upward and a top horizontal wall; a plurality of base contacts secured in the housing at regular intervals and each having a resilient beam and a contact arm formed integral therewith; each resilient beam having a conductive protrusion disposed in the recess, and each contact arm extending along the top horizontal wall into the recess and having a retaining portion facing the conductive protrusion; an insulated pressing cover engageable with the retaining portions and shiftable between a pressing position adjacent to the conductive protrusions and an releasing open position remote therefrom; the retaining portions capable of locking the pressing cover at its pressing position to push the printed circuit board or boards against the resilient beams; and a plurality of cover contacts disposed in the pressing cover and corresponding to the base contacts, so that the retaining portions, the cover contacts and the printed circuit board or boards are electrically connected to each other at the pressing position.
Claim 3
Dependent Claim
27 words
A connector as defined in claim 1, wherein as the cover takes its pressing position, the cover contacts carried thereon are strongly pressed against the retaining portions.
Claim 4
Dependent Claim
41 words
A connector as defined in claim 1 or 2, wherein the retaining portions of the base contacts are rockable up and down so that the cover contacts urge the retaining portions upwards when the cover is shifted to its pressing position.
Claim 5
Dependent Claim
32 words
A connector as defined in claim 3, wherein each of the base contacts further has a mediate stopper integral therewith so as to abut against the cover contact at the pressing position.
Claim 6
Dependent Claim
17 words
A connector as defined in claim 3, wherein the pressing cover is rotatable about the retaining portions.
Claim 7
Dependent Claim
17 words
A connector as defined in claim 4, wherein the pressing cover is rotatable about the retaining portions.
Claim 8
Dependent Claim
21 words
A connector as defined in claim 5, wherein the housing has elastic and arm-shaped holders for rotatably supporting the pressing cover.
Claim 9
Dependent Claim
29 words
A connector as defined in claim 3, wherein the cover is capable of sliding towards and away from the retaining portions so as to engage therewith or disengage therefrom.
Claim 10
Dependent Claim
29 words
A connector as defined in claim 4, wherein the cover is capable of sliding towards and away from the retaining portions so as to engage therewith or disengage therefrom.
