Abstract

A connector ( 1 ) forms an internal space ( 13 ) for accommodating a circuit board ( 12 ) and a case ( 11 ). The connector ( 1 ) includes first terminals ( 2 ), a first core ( 5 ), second terminals, a second core, a housing ( 8 ) and a ventilation path ( 14 ). The first core ( 5 ) holds the first terminals ( 2 ) while exposing both ends. The second core faces and overlaps the first core ( 5 ). The second core holds the second terminals while exposing both ends. The housing ( 8 ) covers at least parts of the first and second cores. The ventilation path ( 14 ) allows the internal space ( 13 ) to communicate with outside air. At least a part of the ventilation path ( 14 ) is constituted by a groove portion ( 512 ) in at least one of overlapping surfaces of the first and second cores ( 5 ) overlapping each other. The groove portion ( 512 ) has a bent shape in the overlapping surface.

First claim

What is claimed is:

1. A connector forming an internal space for accommodating a circuit board together with a case, comprising:
first terminals;
a first core holding the first terminals while exposing both end parts of the first terminals;
second terminals;
a second core facing and overlapping the first core, the second core holding the second terminals while exposing both end parts of the second terminals;
a housing covering at least a part of the first core and at least a part of the second core; and
a ventilation path allowing the internal space to communicate with outside air,
wherein:
at least a part of the ventilation path is constituted by a groove formed in at least one of overlapping surfaces of the first core and the second core overlapping each other, and the groove including:
a first groove portion having a first inner end communicating with the inner space, and a first outer end,
a second groove portion having a second inner end spaced from the first outer end of the first groove portion and a second outer end communicating with the outside air, and
a coupling groove portion extending angularly between the first outer end of the first groove portion and the second inner end of the second groove portion so that the groove has a bent shape in the overlapping surface to avoid interference with the first and second terminals.

2. The connector of claim 1 , wherein the first groove portion and the second groove portion are substantially parallel to one another.

3. The connector of claim 1 , wherein the coupling groove portion is substantially perpendicular to the first groove portion and the second groove portion.

4. A connector forming an internal space for accommodating a circuit board together with a case, comprising:
first terminals;
a first core holding the first terminals while exposing both end parts of the first terminals;
second terminals;
a second core facing and overlapping the first core, the second core holding the second terminals while exposing both end parts of the second terminals;
a housing covering at least a part of the first core and at least a part of the second core; and
a ventilation path allowing the internal space to communicate with outside air, wherein:
at least a part of the ventilation path is constituted by a groove formed in at least one of overlapping surfaces of the first core and the second core overlapping each other,
each of the first core and the second core includes a base formed in a plane direction parallel to the circuit board and a tower projecting from the base toward a side opposite to the internal space,
the groove includes a tower groove formed in the tower, and
the tower groove includes an outer groove portion elongated in a projecting direction of the tower core portion from the base, an inner groove portion elongated in the projecting direction at a position offset in a lateral direction perpendicular to the projecting direction with respect to the outer groove portion and formed on a side of the ventilation path closer to the internal space than the outer groove portion, and a coupling groove portion coupling the outer groove portion and the inner groove portion so that the grove has a bent shape in the overlapping surface.

5. The connector of claim 4 , wherein:
at least either the first terminals or the second terminals include base terminal portions embedded in the base,
the base includes a hole formed at a position deviated from the base terminal portions in the plane direction and constituting a part of the ventilation path,
the base terminal portions are disposed on an extension of the outer groove portion of the tower groove in the projecting direction, and
the inner groove portion of the tower groove communicates with the hole.

6. The connector of claim 5 , wherein the base includes the hole between the base terminal portions.

7. The connector of claim 6 , wherein:
the overlapping surface of the first core and the overlapping surface of the second core include a fitting portion formed by fitting an elongated projection formed on one of the overlapping surfaces into an elongated recess formed in the other overlapping surface,
the fitting portion includes an outer fitting portion along the outer groove portion and an inner fitting portion along the inner groove portion on one side of the tower groove in the lateral direction, and
the inner fitting portion is offset toward the same side as the inner groove portion is offset with respect to the outer groove portion on one side in the lateral direction with respect to the outer fitting portion.
