Abstract

A connector includes an insulating housing that is fixed to a casing of a first device at a communication part through which an opening of the casing of the first device and an opening of a casing of a second device communicate with each other and includes first through holes, conductors that are inserted into the respective first through holes to electrically connect the first device and the second device, an insulating sealing member that includes tubular sealing parts that seal between the conductors and the housing, and a connecting part that connects the sealing parts, and an insulating support member that includes second through holes into which the conductors are inserted, is attached to the housing from a side of the second device, and interposes the sealing member between the support member and the housing to support the sealing parts.

First claim

What is claimed is:

1. A connector comprising:
an insulating housing that is fixed to a casing of a first device at a communication part through which an opening of the casing of the first device and an opening of a casing of a second device communicate with each other, and includes a plurality of first through holes that allow an internal space of the first device and an internal space of the second device to communicate with each other;
a plurality of conductors configured to be inserted into the respective first through holes to electrically connect the first device and the second device;
an insulating sealing member that includes a plurality of annular sealing parts that seal between the conductors and the housing, and a connecting part that connects the sealing parts; and
an insulating support member that includes a plurality of second through holes into which the conductors are inserted, is configured to be attached to the housing from a side of the second device so as to interpose the sealing member between the support member and the housing and support the sealing parts.

2. The connector according to claim 1 , wherein
a material of the housing and a material of the sealing member have resistance to a first liquid stored in the internal space of the first device, and
a material of the support member has resistance to a second liquid different from the first liquid.

3. The connector according to claim 1 , further comprising:
a second insertion structure disposed between the conductors adjacent to each other, wherein
the second insertion structure includes a second concave part provided in one of the sealing member and the support member, and a second insertion wall provided in the other one of the sealing member and the support member,
the second concave part includes a pair of second facing surfaces facing each other in an arrangement direction in which the conductors are arranged and a second connection surface connecting the pair of second facing surfaces, and
the second insertion wall is inserted between the pair of second facing surfaces.

4. The connector according to claim 3 , wherein
a material of the housing and a material of the sealing member have resistance to a first liquid stored in the internal space of the first device, and
a material of the support member has resistance to a second liquid different from the first liquid.

5. The connector according to claim 1 , further comprising:
a first insertion structure disposed between the conductors adjacent to each other, wherein
the first insertion structure includes a first concave part provided in one of the housing and the sealing member, and a first insertion wall provided in the other one of the housing and the sealing member,
the first concave part includes a pair of first facing surfaces facing each other in an arrangement direction in which the conductors are arranged and a first connection surface connecting the pair of first facing surfaces, and
the first insertion wall is inserted between the pair of first facing surfaces.

6. The connector according to claim 5 , further comprising:
a second insertion structure disposed between the conductors adjacent to each other, wherein
the second insertion structure includes a second concave part provided in one of the sealing member and the support member, and a second insertion wall provided in the other one of the sealing member and the support member,
the second concave part includes a pair of second facing surfaces facing each other in an arrangement direction in which the conductors are arranged and a second connection surface connecting the pair of second facing surfaces, and
the second insertion wall is inserted between the pair of second facing surfaces.

7. The connector according to claim 5 , wherein
a material of the housing and a material of the sealing member have resistance to a first liquid stored in the internal space of the first device, and
a material of the support member has resistance to a second liquid different from the first liquid.

8. The connector according to claim 1 , wherein
the support member includes an insulating wall that partitions the conductors adjacent to each other.

9. The connector according to claim 8 , further comprising:
a first insertion structure disposed between the conductors adjacent to each other, wherein
the first insertion structure includes a first concave part provided in one of the housing and the sealing member, and a first insertion wall provided in the other one of the housing and the sealing member,
the first concave part includes a pair of first facing surfaces facing each other in an arrangement direction in which the conductors are arranged and a first connection surface connecting the pair of first facing surfaces, and the first insertion wall is inserted between the pair of first facing surfaces.

10. The connector according to claim 8 , further comprising:
a second insertion structure disposed between the conductors adjacent to each other, wherein
the second insertion structure includes a second concave part provided in one of the sealing member and the support member, and a second insertion wall provided in the other one of the sealing member and the support member,
the second concave part includes a pair of second facing surfaces facing each other in an arrangement direction in which the conductors are arranged and a second connection surface connecting the pair of second facing surfaces, and
the second insertion wall is inserted between the pair of second facing surfaces.

11. The connector according to claim 8 , wherein
a material of the housing and a material of the sealing member have resistance to a first liquid stored in the internal space of the first device, and
a material of the support member has resistance to a second liquid different from the first liquid.
