Abstract

A connector ( 1 ) is mounted on a case ( 12 ) including an internal space ( 120 ) accommodating an electronic board ( 11 ). The connector ( 1 ) includes first terminals ( 3 ), a first core ( 4 ), second terminals ( 5 ), a second core ( 6 ), a housing ( 7 ) and a ventilation passage ( 8 ). The ventilation passage ( 8 ) allows the internal space ( 120 ) of the case ( 12 ) to communicate with outside air. At least a part of the ventilation passage ( 8 ) is constituted by a groove ( 40 ) formed in at least one of mutually overlapping surfaces ( 411, 611 ) of the first core ( 4 ) and the second core ( 6 ). An outer vent ( 81 ) of the ventilation passage ( 8 ) is formed at a position closer to the case ( 12 ) than the receptacle ( 71 ) in a Z direction.

First claim

What is claimed is:

1. A connector to be provided or mounted on a case having an internal space accommodating an electronic board, comprising:
first terminals;
a first core configured to hold the first terminals while exposing both ends of the first terminals;
second terminals;
a second core, the second core, the second core holding the second terminals while exposing both ends of the second terminals;
a housing including a tubular receptacle surrounding one end part of each of the first terminals and the second terminals and having a mating connector inserted therein, the housing at least partially covering the first core and the second core; and
a ventilation passage configured to allow the internal space to communicate with outside air;
wherein:
at least an inner part of the ventilation passage is formed by a groove in at least one of overlapping surfaces of the first core and the second core, the groove having an internal end that opens into the internal space and defines an internal end of the ventilation passage; and
an outer vent of the ventilation passage further has an outer part that communicates with the groove and that opens at a position spaced from the case and spaced from the receptacle in a mounting direction of the connector to the mating connector.

2. The connector of claim 1 , wherein at least a part of the ventilation passage is constituted by an area surrounded by the groove formed in at least one of the overlapping surfaces of the first core and the second core.

3. The connector of claim 1 , wherein the first core or the second core includes a core through hole formed to communicate with the groove, and the core through hole constitutes a part of the ventilation passage.

4. The connector of claim 1 , wherein the ventilation passage is constituted by a part formed by the first core and the second core and a part formed by the housing.

5. The connector of claim 1 , wherein the outer vent is covered by a ventilation film configured to allow a passage of gas while suppressing passage of liquid and solid.

6. The connector of claim 1 , wherein one of the first core and the second core includes ridges formed along the groove at both sides of a formation position of the groove.

7. The connector of claim 1 , wherein an outer peripheral part of the housing is provided with a seal disposed on a side closer to the case than the receptacle, and the outer vent is formed between the receptacle and the seal in a mounting direction.

8. A connector to be provided or mounted on a case having an internal space accommodating an electronic board, comprising:
first terminals;
a first core configured to hold the first terminals while exposing both ends of the first terminals;
second terminals;
a second core facing and overlapping with the first core, the second core holding the second terminals while exposing both ends of the second terminals;
a housing including a tubular receptacle surrounding one end part of each of the first terminals and the second terminals and having a mating connector inserted therein, the housing at least partially covering the first core and the second core; and
a ventilation passage configured to allow the internal space to communicate with outside air, wherein:
at least a part of the ventilation passage is formed by a groove in at least one of overlapping surfaces of the first core and the second core;
an outer vent of the ventilation passage is at a position closer to the case than the receptacle in a mounting direction of the connector to the mating connector;
one of the first core and the second core includes ridges formed along the groove at both sides of a formation position of the groove; and
one of the first core and the second core includes elongated recesses to be fit to the ridges, and the elongated recesses are deeper than the groove.

9. A connector to be provided or mounted on a case having an internal space accommodating an electronic board, comprising:
first terminals;
a first core holding the first terminals while exposing both ends of the first terminals, the first core having first and second intersecting surfaces;
second terminals;
a second core holding the second terminals while exposing both ends of the second terminals, the second core having first and second intersecting surfaces that overlap respectively with the first and second intersecting surfaces of the first core;
a housing including a tubular receptacle surrounding one end part of each of the first terminals and the second terminals and having a mating connector inserted therein, the housing at least partially covering the first core and the second core; and
a ventilation passage configured to allow the internal space of the case to communicate with outside air,
a first part of the ventilation passage being formed by a first groove formed in at least one of the first surface of the first core and the first surface of the second core, the first part of the ventilation passage is open into the internal space of the case, and
a second part of the ventilation passage being formed by a second groove formed in at least one of the second surface of the first core and the second surface of the second core, the second part of the ventilation passage has an internal end that opens into the first part of the ventilation passage and an external end that opens at a position in the housing spaced from both the case and the receptacle.

10. The connector of claim 9 , wherein the first and second intersecting surfaces of the first core intersect at substantially right angles and the first and second intersecting surfaces of the second core intersect at substantially right angles.

11. The connector of claim 9 , wherein the ventilation passage includes further includes a housing through hole externing through the housing a communicating with the external end of the second part of the ventilation passage.
