Hereinafter, embodiments of the present invention will be described in detail. The components having the same function are given the same number, and duplicate explanations are omitted.

Hereinafter, the structure of the terminal pair of the first embodiment will be described with reference to FIG. The terminal pair of this embodiment can be used, for example, for a differential 1-pair connector used for differential signal transmission. The terminal pair of this embodiment includes a first terminal 11 and a second terminal 12 for connecting the plug and the board.

The first terminal 11 has a tip portion 111, an inclined portion 112, and a first straight line portion 113 from the plug side (the side marked with plug ← in the figure) toward the board side (the side marked with → board in the figure). , The twisted portion 114, the first bent portion 115, the second straight portion 116, the second bent portion 117, and the terminal portion 118 in this order.

Similarly, the second terminal 12 has a tip portion 121, an inclined portion 122, a first straight portion 123, a twist portion 124, a first bent portion 125, a second straight portion 126, and a second from the plug side to the substrate side. Each component is included in the order of the bent portion 127 and the terminal portion 128.

The total lengths of the first terminal 11 and the second terminal 12 in the longitudinal direction are the same, and the lengths of the corresponding components of the first terminal 11 and the second terminal 12 are the same.

<Tip part 111, tip part 121>
The tip portions 111 and 121 have a strip shape, and are both located on a predetermined vertical plane (vertical plane A in the figure) and are extended horizontally and in a direction from the plug side to the substrate side. The tip portions 111 and 121 are connected to a plug (or a plug-side terminal) (not shown).

<Inclined portion 112, inclined portion 122>
The inclined portion 112 is located between the tip portion 111 and the first straight portion 113, is located on a predetermined vertical surface (vertical surface A in the figure), and is inclined diagonally downward from the plug side to the substrate side. Stretch in the direction toward.

The inclined portion 122 is located between the tip portion 121 and the first straight portion 123, is located on a predetermined vertical surface (vertical surface A in the figure), and is inclined diagonally upward from the plug side to the substrate side. Stretch in the direction toward.

<First straight line portion 113, first straight line portion 123>
The first straight line portion 113 is located between the inclined portion 112 and the twisted portion 114, is located on a predetermined vertical plane (vertical plane A in the figure), and extends horizontally and in a direction from the plug side to the substrate side. Will be done.

Similarly, the first straight line portion 123 is located between the inclined portion 122 and the twisted portion 124, is located on a predetermined vertical surface (vertical surface A in the figure), and is horizontally and from the plug side to the substrate side. Stretched in the direction.

<Twist part 114, Twist part 124>
The twist portion 114 is formed by twisting a corresponding portion located between the first straight portion 113 and the first bent portion 115 by 90 °.

Similarly, the twist portion 124 is formed by twisting a corresponding portion located between the first straight portion 123 and the first bending portion 125 by 90 °.

By twisting the terminals 90 ° in this way, the board mounts are lined up horizontally without changing the distance between the first terminal 11 and the second terminal 12 (while maintaining the differential coupling state). It is possible to convert to an arrangement, and in board mounting, it is possible to route the same pattern as a normal differential connector. In addition, by connecting to the board while maintaining the differential coupling, it is possible to realize a connector with excellent signal transmission quality.

As shown in FIG. 2, the twist portion 114 is stretched in a direction from the plug side to the substrate side while tilting diagonally downward at the corresponding portion. The twist portion 124 is extended in a direction from the plug side to the substrate side while being inclined diagonally upward at the corresponding portion.

At this time, as shown in FIG. 2, the total length of the inclined portion 112 and the twisted portion 114 of the first terminal 11 in the vertical downward direction is L, and the inclined portion 122 and the twisted portion of the second terminal 12 have a total length. The total length of the vertical extension in 124 is L. Therefore, when arranging the terminal pair in the connector, the heights of the rear end portions 118 and 128 are aligned, so that the tip portion 111 is located above the tip portion 121, and the tip portion 111 and the tip portion 121 are arranged. Will be placed in the connector with an interval of 2 L in the vertical direction.

By arranging the plugs or the differential pairs connected to the plug-side terminals side by side in the vertical direction in this way, the width occupied by one differential terminal pair can be reduced, and the connector width for storing the terminals can be reduced. It can be made smaller. By reducing the connector width, in the case of multiple connectors, a plurality of pairs can be arranged at a narrow pitch, and in the case of one pair of connectors, many pairs can be mounted side by side on one side of the board.

Further, when arranging the terminal pair in the connector, the first terminal 11 and the second terminal 12 are arranged so as to be aligned in the length direction. Since the first terminal 11 and the second terminal 12 are configured to have the same length from the front end portions 111 and 121 to the rear end portions 118 and 128, there is no signal delay in the differential pair and the signal transmission quality is excellent. A connector can be realized.

Further, as shown in FIG. 3, the twisted portions 114 and 124 are stretched while being inclined so as to be spaced apart from each other in the arrangement direction of the terminal portions 118 and 128 connected to the substrate or the substrate side terminal. Assuming that the extension length of the twist portions 114 and 124 in the arrangement direction is d, the end portions 118 and 128 are arranged with a space of 2d in the arrangement direction.

Similarly, the first bent portion 125 is located between the twist portion 124 and the second straight portion 126, and is located in the horizontal direction (direction extending on the horizontal plane B in the figure) and in the direction from the plug side to the substrate side. It is formed by bending the stretched terminal vertically downward.

<Second straight line portion 116, second straight line portion 126>
The second straight line portion 116 is located between the first bent portion 115 and the second bent portion 117, has a strip shape, and is extended in the vertical direction and in the direction from the plug side to the substrate side.

Similarly, the second straight line portion 126 is located between the first bent portion 125 and the second bent portion 127, has a strip shape, and is extended in the vertical direction and in the direction from the plug side to the substrate side.

<Second bent portion 117, second bent portion 127>
The second bent portion 117 is located between the second straight portion 116 and the end portion 118, and is formed by bending a terminal extending in the vertical direction and in the direction from the plug side to the substrate side in the horizontal direction.

Similarly, the second bent portion 127 is located between the second straight portion 126 and the end portion 128, and is formed by bending a terminal extending in the vertical direction and in the direction from the plug side to the substrate side in the horizontal direction. Will be done.
