Abstract

A connector includes: an electric wire; a terminal connected to the electric wire; a housing having a housing space to house a connection portion of the electric wire and the terminal; a seal member to seal an opening portion of the housing space to isolate the connection portion housed in the housing space from an outside; and a heat storage member located in the housing space.

First claim

What is claimed is:

1. A connector comprising:
an electric wire;
a terminal connected to the electric wire;
a housing having a housing space to house a connection portion of the electric wire and the terminal;
a seal member to seal an opening portion of the housing space to isolate the connection portion housed in the housing space from an outside; and
a heat storage member located in the housing space and press-fitted against an inner wall surface of the housing and a surface of the terminal, and
the inner wall surface defines the housing space.

2. The connector according to claim 1 , wherein
the heat storage member has: a case portion capable of sensible heat storage and being at least partially in contact with the connection portion; and a sealing portion capable of latent heat storage and sealed inside the case portion.

3. The connector according to claim 1 , wherein
the heat storage member has a tubular shape surrounding the connection portion, and
the seal member is configured to contact at least a part of at least one of an inner peripheral surface and an outer peripheral surface of the heat storage member.

4. The connector according to claim 1 , wherein
the heat storage member has a protrusion protruding toward the housing, and
the housing has a recess receiving the protrusion.

5. The connector according to claim 1 , further comprising:
a heat transfer member located in the housing space to fill at least a part of a gap remaining around the heat storage member in the housing space.

6. The connector according to claim 5 , wherein
the heat transfer member includes:
a flexible base material; and a heat transfer body having a heat transfer property and is mixed with the base material.

7. The connector according to claim 5 , wherein
the heat transfer member has: a porous sheet material; and a covering material having the heat transfer property and covering the porous sheet material.

8. The connector according to claim 5 , wherein
the heat transfer member has: a porous sheet material; and an impregnation material capable of heat storage and is impregnated in the sheet material.

9. The connector according to claim 5 , wherein
the heat transfer member has a mesh material formed of a wire material having the heat transfer property.

10. The connector according to claim 9 , wherein
the mesh material has conductivity, and
the heat transfer member is located in the gap, and the heat transfer member is located between the electric wire and the terminal.

11. The connector according to claim 1 , wherein
the terminal is connected to the electric wire by crimping the terminal to the electric wire, and the terminal has a recessed crimp trace on its surface, and
the heat storage member is press-fitted to be in pressure contact with a recessed surface of the crimp trace.

12. The connector according to claim 11 , wherein
the heat storage member has a protrusion portion protruding toward the crimp trace, and
the protrusion portion is in surface contact with the recessed surface of the crimp trace.

13. The connector according to claim 12 , wherein
a number of the protrusion portions of the heat storage member is the same as a number of the crimp traces.

14. A connector comprising:
an electric wire;
a terminal connected to the electric wire;
a housing having a housing space to house a connection portion of the electric wire and the terminal;
a seal member to seal an opening portion of the housing space to isolate the connection portion housed in the housing space from an outside;
a heat storage member located in the housing space; and
a holder preventing a displacement of the seal member, wherein
the heat storage member has an extending portion penetrating the seal member and contacting the holder, and
the holder has a heat storage portion located at a contact portion between the holder and the extending portion, the heat storage portion is capable of heat storage.
