Abstract
Abstract A connector includes a connector section having electrical terminals disposed on each of a plug and a socket, with electrical signals being transmitted through the electrical terminals when the plug and the socket are connected to each other. A first pair of metallic pieces is disposed on the plug and a second pair of metallic pieces is disposed on the socket. A connecting section electrically connects either the first pair of metallic pieces to one another or the second pair of metallic pieces to one another, and engagement sections disposed on each of the first metallic pieces and each of the second metallic pieces lockingly connect the first metallic pieces to respective ones of the second metallic pieces to lock the plug and socket together. Selected ones of the metalic pieces may be pushed from outside the plug or the socket to release the locked state of the plug and socket.

Claim 1
Independent Claim
202 words
A connector comprising: a plug; a socket; connector means having electrical terminals disposed in each of said plug and said socket, whereby electrical signals are transmitted through the electrical terminals when the plug and the socket are connected to each other; first and second metallic pieces disposed on the plug; third and fourth metallic pieces disposed on the socket; connection means for electrically connecting one of (i) said first and second metallic pieces with each other and (ii) said third and fourth metallic pieces with each other; a connection detecting means for detecting whether one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces are electrically connected to one another; engagement means disposed on said first and second metallic pieces and said third and fourth metallic pieces, said engagement means causing the plug and the socket to be engaged with each other in a locked state when they are connected; and an unlocking means for pressing one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces from an outer side of either the plug or the socket to release the plug and the socket from said locked state.
Claim 2
Dependent Claim
202 words
A connector comprising: a plug; a socket; connector means having electrical terminals disposed in each of said plug and said socket, whereby electrical signals are transmitted through the electrical terminals when the plug and the socket are connected to each other; first and second metallic pieces disposed on the plug; third and fourth metallic pieces disposed on the socket; connection means for electrically connecting one of (i) said first and second metallic pieces with each other and (ii) said third and fourth metallic pieces with each other; a connection detecting means for detecting whether one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces are electrically connected to one another; engagement means disposed on said first and second metallic pieces and said third and fourth metallic pieces, said engagement means causing the plug and the socket to be engaged with each other in a locked state when they are connected; and an unlocking means for pressing one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces from an outer side of either the plug or the socket to release the plug and the socket from said locked state.
Claim 3
Dependent Claim
14 words
The connector as claimed in claim 1, wherein said unlocking means includes a pushbutton.
Claim 4
Dependent Claim
249 words
A connection method for a connector, comprising the steps of: (a) transmitting electrical signals through electrical terminals disposed on each of a plug and a socket when the plug and the socket are connected to each other; (b) forming a closed circuit loop by connecting first and second metallic pieces, which form an open circuit loop and are disposed on one of the plug and the socket, to third and fourth metallic pieces, respectively, which are disposed on the other of the plug and the socket through connection means for electrically connecting one of (i) the first and second metallic pieces to each other and (ii) the third and fourth metallic pieces to each other when the plug and the socket are connected to each other, said first and second metallic pieces and said third and fourth metallic pieces being locked to each other, respectively, to place the plug and the socket in a locked condition relative to one another by an engagement means; (c) detecting whether one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces are electrically connected to one another; and (d) unlocking said first and second metallic pieces from said third and fourth metallic pieces respectively by pressing one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces from an outer side of one of the plug and the socket to release the plug and the socket from said locked condition.
Claim 5
Dependent Claim
249 words
A connection method for a connector, comprising the steps of: (a) transmitting electrical signals through electrical terminals disposed on each of a plug and a socket when the plug and the socket are connected to each other; (b) forming a closed circuit loop by connecting first and second metallic pieces, which form an open circuit loop and are disposed on one of the plug and the socket, to third and fourth metallic pieces, respectively, which are disposed on the other of the plug and the socket through connection means for electrically connecting one of (i) the first and second metallic pieces to each other and (ii) the third and fourth metallic pieces to each other when the plug and the socket are connected to each other, said first and second metallic pieces and said third and fourth metallic pieces being locked to each other, respectively, to place the plug and the socket in a locked condition relative to one another by an engagement means; (c) detecting whether one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces are electrically connected to one another; and (d) unlocking said first and second metallic pieces from said third and fourth metallic pieces respectively by pressing one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces from an outer side of one of the plug and the socket to release the plug and the socket from said locked condition.
Claim 6
Dependent Claim
44 words
A method as in claim 3, wherein step (d) includes pressing a pushbutton to push said one of (i) said first and second metallic pieces and (ii) said third and fourth metallic pieces to release the plug and the socket from said locked condition.
