Abstract
A connector system with a lever requiring a small force for connecting a pair of male and female connectors by pivoting a lever. The connector system includes a male connector having a cam pin, a female connector having a pin guiding portion into which the cam pin enters, and a lever member having a cam groove with which the cam pin is engaged and pivoted to the female connector. After the male and female connectors are connected completely by pivoting the lever member, the lever member is engaged with a resilient locking piece arranged in the female connector.
Claims5
A connector system requiring a small force by use of an operation lever, said system comprising:
- a first connector having side walls opposite to each other and a cam pin arranged on each of said side walls;
- a second connector having side walls opposite to each other and a pin guiding portion on each of said side walls, said pin guiding portion being capable of receiving said cam pin;
- lever means having a cam groove with which said cam pin is engaged, and having a pair of levers pivoted to said second connector for operating the connection of said first connector and said second connector, said lever means having a connecting portion for connecting said pair of levers on the opposite side of an insertion direction, and wherein said second connector has a rearward side wall portion including a preventing portion for preventing the disconnection, said preventing portion being slidably engaged with the end of a non-connecting side of said lever means;
- a positioning stopper arranged on said rearward side wall portion of said second connector and engaged with an end of one of said two levers;
- and
- a releasing member arranged on a rearward portion of one of the side walls of said first connector and engaged with a notch in said rearward side wall portion of the second connector;
- said cam groove having an open end corresponding to said pin guiding portion of said second connector, when the end of said one of said two levers is engaged with said positioning stopper, and at an initial stage of insertion of said first connector into said second connector, said releasing member engages and urges said end of said one of said two levers to open outwardly and thereby release the engagement of said one of said two levers and said positioning stopper.

A connector system requiring a small force by use of an operation lever, said connector system comprising:
- a frame having side walls opposite to each other, an intermediate wall positioned between said side walls, and top and bottom walls;
- first connector means and second connector means for connection to each other wherein one of said first connector means and said second connector means is a pair of female connectors having a housing which includes side walls opposite to each other and top and bottom walls, and wherein the other connector means is a pair of male connectors having a housing which includes side walls opposite to each other and top and bottom walls;
- said frame surrounding and being slidably mountable on said second connector means before the connection of said first connector means and said second connector means;
- pivotable lever means disposed on said frame for connecting said first connector means and said second connector means within said frame, said lever means having a pair of levers which are pivoted to each side wall of said frame, and a connecting portion for connecting said levers;
- a positioning stopper disposed on said frame and engaged with said lever means in a non-operating position;
- at least one pin arranged on said first connector means;
- at least one cam groove arranged on said lever means and having an open end for advancing said pin in correspondence with a pivoting of said lever means in an inserting direction;
- at least one pin guiding groove arranged on said frame and corresponding in location to said open end of said cam groove when said positioning stopper is engaged with said lever means;
- a releasing member arranged on said first connector means for releasing the engagement of said lever means and said positioning stopper at an initial insertion stage of both said first connector means and said second connector means;
- and
- a preventing portion for preventing disconnection, said portion arranged on each side wall of said frame with which each end of a non-connecting side is slidably engaged.
