Abstract

Abstract The present invention relates to an electrical connecting device for effectuating electrical connection of a first connector unit and a second connector unit by inserting said first connector unit into the accepting port of said second connector unit. This electrical connecting device has a rotating member within said second connector unit as a coupling portion for engaging the second connector unit with the first connector unit. This rotating member rotates in combination with the inserting operation of said first connector unit, and engages with said first connector unit, pushing it in the inserting direction. In addition, the rotating member, when locked in place to secure the first connector unit, can be released by an eject button.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 173 words
An electrical connecting device comprising: (a) a first connector unit with (i) an electrical terminal and (ii) a groove; and (b) a second connector unit with (i) an accepting port, (ii) an electrical terminal, (iii) a rotating member having a hook for engaging the groove in the first connector, and (iv) a rotating lever coupled to said rotating member, wherein the first connector unit and the second connector unit are connected by inserting said first connector unit into the accepting port of the second connector unit, said rotating lever rotates when said lever is pushed by said first connector unit, thus rotating said rotating member, and engaging the hook of the rotating member with the groove of said first connector unit such that the rotating member continues to rotate in combination with the inserting operation of said first connector units, and simultaneously further pushes the first connector unit in the inserting direction, and wherein a coil spring is connected to said rotating member for biasing said first connector unit in the inserting direction.
Claim 2
Dependent Claim 173 words
An electrical connecting device comprising: (a) a first connector unit with (i) an electrical terminal and (ii) a groove; and (b) a second connector unit with (i) an accepting port, (ii) an electrical terminal, (iii) a rotating member having a hook for engaging the groove in the first connector, and (iv) a rotating lever coupled to said rotating member, wherein the first connector unit and the second connector unit are connected by inserting said first connector unit into the accepting port of the second connector unit, said rotating lever rotates when said lever is pushed by said first connector unit, thus rotating said rotating member, and engaging the hook of the rotating member with the groove of said first connector unit such that the rotating member continues to rotate in combination with the inserting operation of said first connector units, and simultaneously further pushes the first connector unit in the inserting direction, and wherein a coil spring is connected to said rotating member for biasing said first connector unit in the inserting direction.
Claim 3
Dependent Claim 35 words
An electrical connecting device as claimed in claim 1, wherein said first connector unit is a cassette type magnetic bubble memory unit, while said second connector unit is a holder unit accommodating the memory unit.
Claim 4
Dependent Claim 59 words
An electrical connecting device as claimed in claim 1, wherein the groove is a plurality of grooves, and wherein at least one of the plurality of grooves is located on each side of said first connector unit and the rotating member has a plurality of hooks such that each hook connected to a rotating member engages a corresponding groove.
Claim 5
Dependent Claim 57 words
An electrical connecting device as claimed in claim 1, wherein a slider, which is operatively connected to the rotating lever, moves in combination with rotation of said rotating member and is provided within said second connector unit, said slider locks said rotating lever after the rotating member is rotated due to insertion of the first connector unit.
Claim 6
Dependent Claim 34 words
An electrical connecting device as claimed in claim 4, wherein said second connector unit is provided with eject button means for moving said slider and for restoring said rotating member to the unlocked condition.
Claim 7
Dependent Claim 39 words
An electrical connecting device as claimed in claim 5, wherein said eject button means restores said rotating member to the unlocked condition and simultaneously electrically disconnects said first and second connector units for withdrawal of the first connector unit.
Claim 8
Dependent Claim 59 words
An electrical connecting device as claimed in claim 5 or 6, wherein said first connector unit further comprises electrical memory data therein and said eject button means is operatively connected with photo cam and photo sensor means for sending and receiving a lock restoration signal to preserve the memory data in tact when the eject button means is operated.
Claim 9
Dependent Claim 25 words
An electrical connecting device as claimed in claim 7, wherein said signal for lock restoration is generated before electrical disconnection of said first connector unit.
Claim 10
Dependent Claim 33 words
An electrical connecting device of claim 1, wherein the electrical terminal of the first connector unit is a male terminal, and the electrical terminal of the second connector unit is a female terminal.
Claim 11
Dependent Claim 121 words
An electrical connecting device, comprising: (a) first connector unit with an electrical terminal; and (b) a second connector unit with an accepting port, an electrical terminal and a rotating member with a coil spring connected thereto, wherein the first connector unit and the second connector unit are connected by inserting said first connector unit into the accepting port of the second connector unit the rotating member provided within the second unit engages the first connector unit, the rotating member rotates in combination with the inserting operation of the first connector unit, and further pushes the first connector unit in the inserting direction, and wherein the coil spring connected to said rotating member urges said first connector unit in the inserting direction.
Claim 12
Dependent Claim 121 words
An electrical connecting device, comprising: (a) first connector unit with an electrical terminal; and (b) a second connector unit with an accepting port, an electrical terminal and a rotating member with a coil spring connected thereto, wherein the first connector unit and the second connector unit are connected by inserting said first connector unit into the accepting port of the second connector unit the rotating member provided within the second unit engages the first connector unit, the rotating member rotates in combination with the inserting operation of the first connector unit, and further pushes the first connector unit in the inserting direction, and wherein the coil spring connected to said rotating member urges said first connector unit in the inserting direction.
