Abstract

In a connector having a housing and a plurality of terminals, the plurality of terminals is configured as surface mount terminals, and each surface mount terminal includes a terminal portion arranged inside the housing, a fixed portion fixed to the housing, and a mount portion soldered to a mount surface of a board. The surface mount terminals are arranged side by side from one side to the other side in a Y-direction when the connector mounted on the mount surface is viewed in an X-direction, and a surface mount terminal having the smallest length dimension from the mount portion to the fixed portion is arranged at the leftmost end in the Y-direction, and the length dimension from the mount portion to the fixed portion is larger or the same dimension according to the arrangement order from the left side to the right side in the Y-direction.

First claim

What is claimed is:

1. A connector comprising:
a housing formed of resin; and
a plurality of terminals formed of metal and installed in the housing, the connector being mounted on a mount surface of a board parallel to a plane defined by a first direction and a second direction which are orthogonal to each other,
wherein at least some of the plurality of terminals are formed as a plurality of surface mount terminals, and each of the plurality of mount terminals includes a terminal portion arranged inside the housing, a fixed portion fixed to the housing, and a mount portion soldered to an electrically conductive pad portion formed on the mount surface of the board,
wherein the plurality of surface mount terminals is arranged from one side to the other side in the second direction when the connector mounted on the mount surface of the board is viewed in the first direction, a surface mount terminal having a smallest length dimension from the mount portion to the fixed portion among the plurality of surface mount terminals is arranged at an outermost end on the one side in the second direction, and a length dimension from the mount portion to the fixed portion becomes larger or is the same in order of an arrangement of the plurality of surface mount terminals from the one side to the other side in the second direction,
wherein the plurality of surface mount terminals is arranged so that the arrangement of the plurality of surface mount terminals arranged side by side from the one side to the other side in the second direction forms at least two rows when the mount surface of the board is viewed in a third direction orthogonal to the first direction and the second direction, and
wherein the surface mount terminal having the smallest length dimension from the mount portion to the fixed portion in each of the at least two rows is arranged at the outermost end on the one side in the second direction, and surface mount terminals in the at least two rows arranged at the outermost end on the one side in the second direction are arranged at positions which overlap each other when the connector mounted on the mount surface of the board is viewed in the first direction.

2. The connector according to claim 1 , wherein the plurality of terminals includes through-hole terminals, each of the through-hole terminals comprises another terminal portion arranged inside the housing, another fixed portion fixed to the housing, and another mount portion soldered in a state where the another mount portion is electrically connected to a through-hole formed on the mount surface of the board, and terminals each having a largest length dimension from the mount portion to the fixed portion among the plurality of terminals are the through-hole terminals.

3. The connector according to claim 2 , wherein a surface mount terminal having the fixed portion located just under the fixed portion of each of the through-hole terminals is provided with a crank portion bent in a crank shape between the fixed portion and the mount portion of the surface mount terminal having the fixed portion located just under the fixed portion of each of the through-hole terminals, whereby the mount portion of the surface mount terminal thereof is soldered to the electrically conductive pad portion of the board at a position which is farther away from the housing than the another mount portion of each of the through-hole terminals.

4. A connector comprising:
a housing formed of resin; and
a plurality of terminals formed of metal and installed in the housing, the connector being mounted on a mount surface of a board parallel to a plane defined by a first direction and a second direction which are orthogonal to each other,
wherein at least some of the plurality of terminals are formed as a plurality of surface mount terminals, and each of the plurality of mount terminals includes a terminal portion arranged inside the housing, a fixed portion fixed to the housing, and a mount portion soldered to an electrically conductive pad portion formed on the mount surface of the board,
wherein the plurality of surface mount terminals is arranged from one side to the other side in the second direction when the connector mounted on the mount surface of the board is viewed in the first direction, a surface mount terminal having a smallest length dimension from the mount portion to the fixed portion among the plurality of surface mount terminals is arranged at an outermost end on the one side in the second direction, and a length dimension from the mount portion to the fixed portion becomes larger or is the same in order of an arrangement of the plurality of surface mount terminals from the one side to the other side in the second direction,
wherein the plurality of terminals includes through-hole terminals, and
wherein a surface mount terminal having the fixed portion located just under the fixed portion of each of the through-hole terminals is provided with a crank portion bent in a crank shape between the fixed portion and the mount portion of the surface mount terminal having the fixed portion located just under the fixed portion of each of the through-hole terminals, whereby the mount portion of the surface mount terminal thereof is soldered to the electrically conductive pad portion of the board at a position which is farther away from the housing than the another mount portion of each of the through-hole terminals.

5. The connector according to claim 4 , wherein, wherein the plurality of surface mount terminals is arranged so that the arrangement of the plurality of surface mount terminals arranged side by side from the one side to the other side in the second direction forms at least two rows when the mount surface of the board is viewed in a third direction orthogonal to the first direction and the second direction, and
wherein the surface mount terminal having the smallest length dimension from the mount portion to the fixed portion in each of the at least two rows is arranged at the outermost end on the one side in the second direction, and surface mount terminals in the at least two rows arranged at the outermost end on the one side in the second direction are arranged at positions which overlap each other when the connector mounted on the mount surface of the board is viewed in the first direction.

6. The connector according to claim 4 , wherein each of the through-hole terminals comprises another terminal portion arranged inside the housing, another fixed portion fixed to the housing, and another mount portion soldered in a state where the another mount portion is electrically connected to a through-hole formed on the mount surface of the board, and terminals each having a largest length dimension from the mount portion to the fixed portion among the plurality of terminals are the through-hole terminals.

7. The connector according to claim 5 , wherein each of the through-hole terminals comprises another terminal portion arranged inside the housing, another fixed portion fixed to the housing, and another mount portion soldered in a state where the another mount portion is electrically connected to a through-hole formed on the mount surface of the board, and terminals each having a largest length dimension from the mount portion to the fixed portion among the plurality of terminals are the through-hole terminals.
