Abstract

Provided is an electrical connector for a print ink cartridge. The electrical connector includes a housing including a thin protrusion having a rectangle shape on one side portion thereof, a plurality of pin grooves spaced apart predetermined intervals from each in one side lower portion of the protrusion, a plurality of format ribs spaced apart predetermined intervals from each other in the other side of the protrusion, and coupling bosses having a wedge shape separately protruding on both sides of each of the ribs, a connection terminal serving as a torsion spring, the connecting terminal including a pin connector inserted into each of the pin grooves of the housing and fixed in a straight line orientation, a wound coupling insert fitted onto each of the coupling bosses to give elasticity thereto, a parallel extending from the coupling insert and along each of the ribs, a bend bent at a front end of the parallel, and a socket connector bent in a state where the socket connector is connected to the bend, the socket connector being connected to an external socket, and a cover integrally fixed to the housing by a plurality of coupling hooks disposed on the housing, the cover including pine connector grooves pressing the pin connector of the coupling terminal in a downward direction in a side surface of the cover.

Claims

1. An electrical connector for a print ink cartridge, comprising:

a housing including;

a thin protrusion having a rectangle shape on one side portion thereof;

a plurality of pin grooves spaced apart predetermined intervals from each in one side lower portion of the protrusion;

a plurality of format ribs spaced apart predetermined intervals from each other in the other side of the protrusion; and

coupling bosses having a wedge shape separately protruding on both sides of each of the ribs;

a connection terminal serving as a torsion spring, the connecting terminal including;

a pin connector inserted into each of the pin grooves of the housing and fixed in a straight line orientation;

a wound coupling insert fitted into each of the coupling bosses to give elasticity thereto;

a parallel extending from the coupling insert and along each of the ribs;

a bend bent at a front end of the parallel; and

a socket connector bent in a state where the socket connector is connected to the bend, the socket connector being connected to an external socket; and

a cover integrally fixed to the housing by a plurality of coupling hooks disposed on the housing, the cover including pin connector grooves pressing the pin connector of the coupling terminal in a downward direction in a side surface of the cover.

2. The electrical connector for the print ink cartridge of claim 1, wherein the housing includes a stopping jaw on left and right surfaces of the each of the ribs, and the parallel of the connection terminal is inserted and fixed into/to the stopping jaw.

3. The electrical connector for the print ink cartridge of claim 1, wherein, when the connection terminal is connected to an external socket, a pair of connection terminals is connected to a terminal connection portion to provide a double contact structure.

4. The electrical connector for the print ink cartridge of claim 1, wherein the connection terminal is perpendicular to a coupling central position of the coupling insert fitted onto each of the coupling bosses of the housing and a contact position of the socket connector connected to the terminal connection portion of the socket.

5. The electrical connector for the print ink cartridge of claim 1, wherein the cover includes a partition within an inner space thereof, and the partition blocks between the coupling bosses of the housing.

6. The electrical connector for the print ink cartridge of claim 1, wherein when the cover is coupled to the housing, a height H of each of the pin connector grooves of the cover is less than a minimum height h of the pin connector from an external printed circuit board, and the pin connector is aligned at the same height as the height H of each of the pin connector grooves to provide the pin connector having an uniform flatness.
