Electrical connector and assembly thereof
It is made possible with a simple configuration to electromagnetically shield connection leg portions disposed below a signal transmission medium immediately when both connectors are fitted to each other. A connector main body portion are preliminarily provided with a terminal portion of the signal transmission medium and a transmission-medium-side shield cover that extends from between the another connector (second connector) and the connection leg portions on a transmission-medium side, and the connection leg portions on the transmission-medium side disposed below the signal transmission medium (thin coaxial cables) is covered from above with the transmission-medium-side shield cover when both the connectors are fitted to each other, so that electromagnetic interference (EMI) is successfully prevented from occurring.
1. An electrical connector comprising:
a connector main body portion including
a fitting protrusion that is inserted and fitted from above into a fitting recess of a receiving connector mounted on a printed circuit board which has first and second connection leg portions soldered thereto, a terminal portion of a signal transmission medium being connected to the connector main body portion and extending above, apart from, and substantially in parallel to the printed circuit board, and the first connection leg portion, which is on a transmission-medium side of the receiving connector, being disposed below the terminal portion of the signal transmission medium,
a transmission-medium-side shield cover extending from between the terminal portion of the signal transmission medium and the first connection leg portion, and the transmission-medium-side shield cover extending along the first connection leg portion so as to cover the first connection leg portion from above, and
an anti-transmission-medium-side shield cover that covers the second connection leg portion of the receiving connector from above, the second connection leg portion being disposed on an anti-transmission-medium side extending from the connector main body portion in a direction opposite of the first connection leg portion,
wherein end edge portions of the transmission-medium-side shield cover and the anti-transmission-medium side shield cover, respectively, include fitting supporting portions that contact or come close to a surface of the printed circuit board in a first position where the electrical connector and the receiving connector are fitted together.
2. The electrical connector according to claim 1 , wherein the transmission-medium-side shield cover and the anti-transmission-medium side shield cover respectively, include fitting guide portions that come into contact with an outer surface of the receiving connector in an operation of fitting together the electrical connector and the receiving connector.
3. An electrical connector assembly, comprising:
a first connector including a connector main body having a fitting protrusion thereon;
a second connector including a fitting recess into which the fitting protrusion of the connector main body is inserted and fitted from above, the second connector being mounted on a printed circuit board with first and second connection leg portions joined thereto; and
a signal transmission medium having a terminal portion thereof connected to the connector main body portion of the first connector so as to extend above, apart from, and substantially in parallel to the printed circuit board,
wherein the first connection leg portion, which is on a transmission-medium side of the second connector is disposed below the terminal portion of the signal transmission medium connected to the connector main body,
wherein the connector main body portion of the first connector includes
a transmission-medium-side shield cover extending from between the terminal portion of the signal transmission medium and the first connection leg portion, the transmission-medium-side shield cover extending along the first connection leg portion so as to cover the first connection leg portion from above, and
an anti-transmission-medium-side shield cover that covers the second connection leg portion of the second connector from above, the second connection leg portion being disposed on an anti-transmission-medium side extending from the connector main body portion in a direction opposite of the first connection leg portion,
wherein end edge portions of the transmission-medium-side shield cover and the anti-transmission-medium side shield cover, respectively, include fitting supporting portions that contact or come close to a surface of the printed circuit board in a first position where the first connector and the second connector are fitted together.
4. The electrical connector according to claim 3 , wherein the transmission-medium-side shield cover and the anti-transmission-medium side shield cover respectively, include fitting guide portions that come into contact with an outer surface of the second connector in an operation of fitting together the first connector and the second connector.
