Abstract
To improve airtightness while reducing a usage amount of a resin for a sealing operation. A terminal block 20 of an electronic device 100 includes a resinous portion 21, a terminal member 23, and a connection member 25. Then, since a first area A1 and a second area A2 are divided by a partition wall 273 in the terminal block 20, it is possible to individually charge a charging resin 29A for blocking a through-hole A22 and a charging resin 29B for blocking a boundary portion between the terminal member 23 and the resinous portion 21. Thus, since the charging amounts of the charging resins 29A and 29B may be respectively adjusted, it is possible to appropriately charge the charging resin for improving the airtightness and to reduce the usage amount of the charging resin for a sealing operation.
Claims16
A terminal block comprising:
- a terminal member of which one end side is equipped with a first terminal having an opening and the other end side different from the one end side is equipped with a second terminal;
- a connection member that includes a flange extending outward from about a center of a main body and is inserted from the side of the second terminal into the opening of the first terminal of the terminal member so that the flange is fixed while contacting the first terminal;
- and
- a resinous portion that covers the peripheries of the terminal member and the connection member while at least one of the first terminal and the connection member is exposed at the side of the first terminal and the second terminal is exposed at the side of the second terminal,
- wherein the resinous portion includes a cylindrical side wall that is formed at the end of the side of the second terminal so as to extend toward the side of the second terminal in the extension direction of the terminal member and to surround the terminal member and a partition wall that divides an area surrounded by the side wall into a first area and a second area,
- wherein the terminal member protrudes from a bottom surface of the first area, and
- wherein a bottom surface of the second area is provided with a through-hole communicating with an end surface the side of the second terminal of the connection member.
