Connector with terminal overstress prevention
In a substrate-side housing of a plug connector and a housing of a socket connector, an abutment receiving portion and a columnar projection are provided to disable the socket connector from being inserted into the substrate-side housing when the socket connector is misaligned beyond a movable range of a fitting-side housing of the plug connector.
1. A connector with terminal overstress prevention comprising:
a first connector to be mounted on a first substrate; and
a second connector to be mounted on a second substrate,
wherein the first connector includes
a substrate-side housing to be mounted on the first substrate,
a plurality of divided housings, arranged inside of the substrate-side housing, and displaceable relative to the substrate-side housing, and
a plurality of terminals that supports respective divided housings displaceably relative to the substrate-side housing,
wherein the second connector includes a housing having columnar projections which protrude in an inserting direction into the first connector and which disable the second connector from being inserted into the substrate-side housing by abutting against the substrate-side housing when the second connector is misaligned beyond a movable range of the divided housings, and
wherein the substrate-side housing includes receiving chambers that hold the plurality of the divided housings and engaging grooves receiving the columnar projections.
2. The connector according to claim 1 , wherein the substrate-side housing has abutting portions that disable the second connector from being inserted into the substrate-side housing by abutting against the housing when the second connector is misaligned beyond a movable range of the plurality of the divided housings, the abutting portions being a peripheral wall that forms a fitting port for the second connector.
3. The connector according to claim 1 , wherein the columnar projections are located near a longitudinal center of the housing of the second connector.
4. The connector according to claim 1 ,
wherein the housing of the second connector has a fit connecting part to be inserted in the substrate-side housing of the first connector, and
wherein the columnar projections protrude from the fit connecting part in the inserting direction into the first connector.
5. The connector according to claim 2 , the peripheral wall is shaped in a rectangular cylinder, having a pair of long-side walls along a width direction and a pair of short-side walls along a front-rear direction.
6. The connector according to claim 2 , wherein the abutting portions form an abutment receiving portion which prevents, by the divided housings abutting to the abutment receiving portions, the divided housings from falling off of the receiving chambers, the divided housings being displaced in the removing direction from the receiving chambers.
7. The connector according to claim 1 , wherein the engaging grooves are located between the adjacent divided housings.
