Fitting confirmation construction of connector for connecting circuit board
View Patent ↗A fitting confirmation construction includes a confirmation part in a first connector and a confirmation opening in a second connector. A rib is provided in the confirmation opening. A height of the confirmation part is equal to a height of the rib and the confirmation part and the rib are positioned on a same line, on a viewing direction which is viewed from an obliquely upper position rearward in an inserting direction of the second connector through the confirmation opening, in a state that the second connector is completely fit with the first connector.
1. A fitting confirmation construction of a connector for connecting a circuit board, the connector including a first connector which is provided on the circuit board and a second connector which is provided at a flat circuit element and configured to be inserted into the first connector to be fit, the fitting confirmation construction comprising:
a confirmation part, provided at a housing of the first connector;
a confirmation opening, provided in a housing of the second connector; and
a rib, provided in the confirmation opening,
wherein a height of the confirmation part is equal to a height of the rib and the confirmation part and the rib are positioned on a same line, on a viewing direction which is viewed through the confirmation opening from an obliquely upper position rearward in an inserting direction of the second connector, in a state that the second connector is completely fit with the first connector.
2. The fitting confirmation construction according to claim 1 , further comprising:
a lock arm provided in the housing of the second connector;
outer protection walls, provided on the housing of the second connector, and disposed at a left side and a right side of the lock arm respectively; and
a lock projection provided on the housing of the first connector,
wherein a pair of confirmation openings are provided between the lock arm and both of the left side and the right side of the outer protection walls respectively, and
the rib is disposed rearward of the lock projection in the inserting direction in the state that the second connector is completely fit with the first connector.
3. The fitting confirmation construction according to claim 1 , wherein the confirmation part is a straight edge of the housing of the first connector, and
in the state that the second connector is completely fit with the first connector, a straight line connecting the straight edge with a front edge of the rib in the inserting direction is equal to the viewing direction, and the front edge is on the straight edge viewed in the viewing direction.
4. The fitting confirmation construction according to claim 3 , wherein an angle between the straight line and the inserting direction is in a range from 30 degree to 35 degree.
5. The fitting confirmation construction according to claim 1 , wherein
at least one other structure is provided above the first connector or above and at sides of the first connector.
