Abstract
Abstract An electrical connector ( 1 ) includes an insulative housing ( 2 ) for receiving a sheet-like connection member, a plurality of electrical contacts ( 4 ) received in the housing, and an operation member ( 3 ) mounted onto the housing. The housing has a lower wall ( 24 ) and an upper wall ( 22 ) opposite to the lower wall. The upper wall forms a plurality of second ribs on a bottom thereof. Each second rib forms a curved end ( 226 ) exposed outwardly from an edge ( 222 ) of the upper wall. The operation member forms an elongate pressing portion ( 324 ) at a bottom thereof, and a channel ( 322 ) defined in a main face thereof opposite from the pressing portion. The operation member is rotatable from an open position to a closed position, with the channel pivoting about the curved ends of the first ribs of the housing, thereby pressing the connection member upon the contact arms of the contacts.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
176 words
An electrical connector comprising: an insulative housing for receiving a sheet-like connection member, the insulative housing having a lower wall and an upper wall, the upper wall forming a plurality of first ribs at a bottom thereof, every two adjacent first rib defining a first passageway therebetween, each first rib forming a curved end exposed outwardly from an edge of the upper wall; a plurality of electrical contacts received in the housing, each contact comprising a securing arm and a contact arm bifurcated from the securing arm, the securing arm being received in a corresponding passageway; an operation member pivotably engaging the housing, the operation member having a pressing portion at a bottom thereof and a channel in a portion thereof opposite from the pressing portion, the operation member being rotatable with pivoting about the curved ends of the first ribs of the housing from an open position where the connection member is admitted into the housing to a closed portion where the pressing portion presses the connection member against the contact arms of the contacts.
Claim 2
Dependent Claim
176 words
An electrical connector comprising: an insulative housing for receiving a sheet-like connection member, the insulative housing having a lower wall and an upper wall, the upper wall forming a plurality of first ribs at a bottom thereof, every two adjacent first rib defining a first passageway therebetween, each first rib forming a curved end exposed outwardly from an edge of the upper wall; a plurality of electrical contacts received in the housing, each contact comprising a securing arm and a contact arm bifurcated from the securing arm, the securing arm being received in a corresponding passageway; an operation member pivotably engaging the housing, the operation member having a pressing portion at a bottom thereof and a channel in a portion thereof opposite from the pressing portion, the operation member being rotatable with pivoting about the curved ends of the first ribs of the housing from an open position where the connection member is admitted into the housing to a closed portion where the pressing portion presses the connection member against the contact arms of the contacts.
Claim 3
Dependent Claim
24 words
The electrical connector as claimed in claim 1 , further comprising a pair of positioning members mounted on two opposite ends of the housing.
Claim 4
Dependent Claim
43 words
The electrical connector as claimed in claim 1 , wherein a plurality of second ribs is defined in the lower wall of the housing, every two adjacent second ribs defining a second passageway therebetween for receiving the contact arm of a corresponding contact.
Claim 5
Dependent Claim
28 words
The electrical connector as claimed in claim 1 , wherein a contact portion is formed at a free end of the contact arm of each of the contact.
Claim 6
Dependent Claim
53 words
The electrical connector as claimed in claim 4 , wherein when the pressing portion of the operation member presses the connection member against the contact portions of the contacts, the contact portions exert resilient forces on the operation member to provide a moment facilitating the operation member to rotate toward the closed position.
Claim 7
Dependent Claim
40 words
The electrical connector as claimed in claim 1 , wherein the upper wall of the housing has a substantially U-shaped profile and comprises an elongate portion and a pair of end portions at two opposite ends of the elongate portion.
Claim 8
Dependent Claim
26 words
The electrical connector as claimed in claim 6 , wherein a chamber is defined between each of the pair of end portions and the elongate portion.
Claim 9
Dependent Claim
40 words
The electrical connector as claimed in claim 7 , wherein a projecting portion extends from an inner side of each sidewall of the housing under the end portion of the upper wall, the projecting portion defining a curved recess therein.
Claim 10
Dependent Claim
32 words
The electrical connector as claimed in claim 8 , wherein the operation member comprises an actuation portion and a pair of latches formed at the two opposite ends of the elongate portion.
Claim 11
Dependent Claim
29 words
The electrical connector as claimed in claim 9 , wherein a pivot is formed on each latch, the pivot being pivotably received in a corresponding recess of the housing.
Claim 12
Dependent Claim
43 words
