Movable connector
A movable connector with which an insertion force of a connection object that places a load on a solder portion can be reduced, that has a floating function, and that can be reduced in size is provided. As a result of a pushing operation in which an operation housing is pushed into a fixed housing, a relay terminal is conductively connected to a substrate connection terminal, which is in conductive contact with a substrate, and a pin terminal, which is disposed in a movable housing and serves as the connection object, in the movable housing. Accordingly, the overall size of the movable connector can be reduced. In addition, the insertion force applied to the pin terminal is not applied to the solder portion by which the movable connector is fixed to the substrate, so that conduction failure does not occur.
1. A movable connector comprising:
a fixed housing to be fixed to a substrate;
a movable housing disposed in the fixed housing and into which a connection object is to be inserted;
a substrate connection terminal including
a substrate connection portion to be soldered to the substrate,
a support spring that supports the movable housing so that the movable housing is movable with respect to the fixed housing, and
an inner contact section disposed in the movable housing;
an operation housing that is combined with the movable housing as a result of a pushing operation in which the operation housing is pushed into an interior space of the fixed housing; and
a relay terminal that moves together with the operation housing in the pushing operation and comes into conductive contact with the connection object and the inner contact section of the substrate connection terminal in the movable housing.
2. The movable connector according to claim 1 , wherein the interior space of the fixed housing includes a housing accommodating section that accommodates the movable housing and the operation housing and a support spring accommodating section in which the support spring extends.
3. The movable connector according to claim 1 , wherein the substrate connection terminal includes a first contact piece that comes into pressure contact with the relay terminal in the pushing operation.
4. The movable connector according to claim 1 , wherein the relay terminal includes a second contact piece that comes into pressure contact with the connection object and the substrate connection terminal in the pushing operation.
5. The movable connector according to claim 4 ,
wherein the second contact piece includes
a first contact portion that comes into conductive contact with the connection object,
a second contact portion that comes into pressure contact with the substrate connection terminal, and
a spring portion that connects the first contact portion to the second contact portion and exerts a reaction force that presses the first contact portion against the connection object when the second contact portion comes into pressure contact with the substrate connection terminal.
6. The movable connector according to claim 1 , wherein the relay terminal includes a projection,
wherein the operation housing has a retaining groove in which the projection is retained in a movable manner with a gap provided therebetween, and
wherein the relay terminal is movable with respect to the operation housing over a range defined by the gap.
7. The movable connector according to claim 1 , wherein the substrate connection terminal includes a first base portion held by the movable housing,
wherein the relay terminal includes a second base portion held by the operation housing, and
wherein the first base portion and the second base portion are arranged in a pushing direction in which the operation housing is pushed in the pushing operation.
8. The movable connector according to claim 1 , wherein the operation housing and the movable housing include temporarily-fitted-state retaining portions that restrain a movement of the operation housing in a pushing direction in which the operation housing is pushed in the pushing operation and a pulling direction that is opposite to the pushing direction in a temporarily fitted state before the operation housing and the movable housing are combined together in a completely fitted state.
9. The movable connector according to claim 1 , wherein the operation housing and the movable housing include completely-fitted-state retaining portions that restrain a movement of the operation housing in a pulling direction in which the operation housing is pulled out of the movable housing in a completely fitted state in which the operation housing and the movable housing are combined together.
