Summary of the Invention

Problems to be Solved by the Invention

[0004] For example, in a connector for differential signal transmission, since the width occupied by one pair of differential terminals becomes large, arranging a plurality of pairs increases the width of the connector, which is disadvantageous for multi-row and parallel mounting of a plurality of connectors.

[0005] Therefore, an object of the present invention is to provide a terminal pair capable of reducing the width of the connector.

[0007] The first terminal and the second terminal include respective components in the order of a tip portion, a twist portion, and a termination portion from the plug side toward the substrate side. The tip portion has a strip shape and is all located on a predetermined vertical plane and extends in the horizontal direction and in the direction from the plug side toward the substrate side. The twist portion is formed by twisting the corresponding portions of the first terminal and the second terminal by 90°. The termination portion has a strip shape and is all located on a predetermined horizontal plane and extends in the horizontal direction and in the direction from the plug side toward the substrate side.

Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described in detail. Components having the same function are denoted by the same reference numerals, and redundant descriptions are omitted.

Example

[0011] Hereinafter, with reference to FIG. 1, the structure of the terminal pair of Example 1 will be described. The terminal pair of this example can be used, for example, in a differential 1-pair connector for differential signal transmission. The terminal pair of this example includes a first terminal 11 and a second terminal 12 that connect a plug and a substrate.

[0012] The first terminal 11 includes components in the order of a tip portion 111, an inclined portion 112, a first straight portion 113, a twist portion 114, a first bent portion 115, a second straight portion 116, a second bent portion 117, and a terminal end portion 118 from the plug side (the side indicated as plug ← in the figure) toward the substrate side (the side indicated as → substrate in the figure).

[0013] Similarly, the second terminal 12 includes components in the order of 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, a second bent portion 127, and a terminal end portion 128 from the plug side toward the substrate side.

[0014] Note that the total lengths of the first terminal 11 and the second terminal 12 in the longitudinal direction are equal, and the lengths of the corresponding components of the first terminal 11 and the second terminal 12 are equal.

[0015] <Tip portions 111 and 121> The tip portions 111 and 121 are in strip shape and are both located on a predetermined vertical plane (vertical plane A in the figure) and extend in the horizontal direction and in the direction from the plug side toward the substrate side. The tip portions 111 and 121 are connected to a plug (or a plug-side terminal) not shown.

[0016] <Inclined portions 112 and 122> The inclined portion 112 is located between the tip portion 111 and the first straight portion 113, is located on a predetermined vertical plane (vertical plane A in the figure), and extends in the direction from the plug side toward the substrate side while inclining obliquely downward.

[0017] The inclined portion 122 is located between the tip portion 121 and the first straight portion 123, is positioned on a predetermined vertical plane (vertical plane A in the figure), and extends in a direction from the plug side toward the substrate side while inclining obliquely upward.

[0018] <The first straight portion 113, the first straight portion 123> The first straight portion 113 is located between the inclined portion 112 and the twist portion 114, is positioned on a predetermined vertical plane (vertical plane A in the figure), and extends in a horizontal direction and in a direction from the plug side toward the substrate side.

[0019] Similarly, the first straight portion 123 is located between the inclined portion 122 and the twist portion 124, is positioned on a predetermined vertical plane (vertical plane A in the figure), and extends in a horizontal direction and in a direction from the plug side toward the substrate side.

[0020] <The twist portion 114, the twist portion 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°.

[0021] Similarly, the twist portion 124 is formed by twisting a corresponding portion located between the first straight portion 123 and the first bent portion 125 by 90°.

[0022] By twisting the terminals in this way, it is possible to convert to an arrangement in which they are arranged horizontally at the substrate mounting portion without changing the distance between the first terminal 11 and the second terminal 12 (while maintaining the differential coupling state), and in substrate mounting, it is possible to route in the same pattern as a normal differential connector. Also, by being able to connect to the substrate while maintaining the differential coupling, a connector with excellent signal transmission quality can be realized.

[0023] As shown in FIG. 2, the twist portion 114 extends in a direction from the plug side toward the substrate side while inclining obliquely downward at the corresponding location. The twist portion 124 extends in a direction from the plug side toward the substrate side while inclining obliquely upward at the corresponding location.

[0024] At this time, as shown in FIG. 2, the total vertical downward extension lengths of the inclined portion 112 and the twist portion 114 of the first terminal 11 are L, and the total vertical upward extension lengths of the inclined portion 122 and the twist portion 124 of the second terminal 12 are L. Therefore, when arranging the terminal pair in the connector, in order to arrange the rear end portions 118 and 128 at the same height, the front end portion 111 is located above the front end portion 121, and the front end portion 111 and the front end portion 121 are arranged in the connector with a vertical interval of 2L.

[0025] In this way, by arranging the differential pairs connected to the plug or the plug-side terminals vertically one above the other, the width occupied by one pair of differential terminals can be reduced, and the width of the connector for storing the terminals can be reduced. By reducing the connector width, in the case of a multi-row connector, a plurality of pairs can be arranged at a narrow pitch, and in the case of a single-pair connector, a large number can be arranged side by side and mounted on one side of the substrate.

[0026] Also, when arranging the terminal pair in the connector, the first terminal 11 and the second terminal 12 are arranged aligned in the length direction. By configuring the first terminal 11 and the second terminal 12 to have the same length from the front end portions 111 and 121 to the rear end portions 118 and 128, a connector with no signal delay in the differential pair and excellent signal transmission quality can be realized.

[0027] Also, as shown in FIG. 3, the twist portions 114 and 124 are extended while being inclined so as to be spaced apart from each other in the arrangement direction of the terminal end portions 118 and 128 connected to the substrate or the substrate-side terminals. Assuming that the extension lengths of the twist portions 114 and 124 in the arrangement direction are d, the terminal end portions 118 and 128 will be arranged with a space of 2d in the arrangement direction.

[0028] <The first bending portions 115, the first bending portions 125> The first bent portion 115 is located between the twist portion 114 and the second straight portion 116, and is formed by bending a terminal extending in the horizontal direction (the direction extending on the horizontal plane B in the figure) and from the plug side toward the substrate side downward vertically.

[0029] Similarly, the first bent portion 125 is located between the twist portion 124 and the second straight portion 126, and is formed by bending a terminal extending in the horizontal direction (the direction extending on the horizontal plane B in the figure) and from the plug side toward the substrate side downward vertically.

[0030] <The second straight portion 116, the second straight portion 126> The second straight portion 116 is located between the first bent portion 115 and the second bent portion 117, is in a strip shape, and extends in the vertical direction and from the plug side toward the substrate side.

[0031] Similarly, the second straight portion 126 is located between the first bent portion 125 and the second bent portion 127, is in a strip shape, and extends in the vertical direction and from the plug side toward the substrate side.

[0032] <The second bent portion 117, the second bent portion 127> The second bent portion 117 is located between the second straight portion 116 and the terminal end portion 118, and is formed by bending a terminal extending in the vertical direction and from the plug side toward the substrate side horizontally.

[0033] Similarly, the second bent portion 127 is located between the second straight portion 126 and the terminal end portion 128, and is formed by bending a terminal extending in the vertical direction and from the plug side toward the substrate side horizontally.

[0034] <The terminal end portion 118, the terminal end portion 128> The terminal end portions 118 and 128 are located closest to the substrate side, are in a strip shape, and are both located on a predetermined horizontal plane (the horizontal plane C in the figure) and extend in the horizontal direction and from the plug side toward the substrate side. The terminal end portions 118 and 128 are connected to the substrate (or the substrate-side terminals).

[0035] <Example 1 of a connector incorporating terminal pairs 11 and 12> Figures 4 to 7 show Example 1 (Connector 1) of a connector incorporating terminal pairs 11 and 12 of Example 1. As shown in Figure 4, Connector 1 is formed by housing and fixing a pair of terminal pairs 11 and 12 in an insulator case 13 while maintaining the above-described positional relationship. As shown in Figure 5, the first bent portions 115 and 125, the second straight portions 116 and 126, the second bent portions 117 and 127, and the terminal ends 118 and 128 are exposed to the outside from the back side of the case 13.

[0036] As shown in Figure 7, which is a cross-sectional view taken along the cross-sectional indication line 7-7 in Figure 6, the case 13 that houses the terminal pairs 11 and 12 includes a cylindrical plug insertion portion 131 that is located on the plug side and through which the plug is inserted (housed), and a filling portion 132 that is located on the substrate side and filled with resin to fix the terminal pairs 11 and 12. The tip portions 111 and 121 are exposed from the filling portion 132 and are located within the plug insertion portion 131.

[0037] <Example 2 of a connector incorporating terminal pairs 11 and 12> As shown as Connector 2 in Figure 8, a plurality of Connectors 1 of Example 1 may be connected in parallel to form a connector.

[0038] <Example 3 of a connector incorporating terminal pairs 11 and 12> As shown as Connector 3 in Figures 9 and 10, a connector may be formed by arranging a plurality of terminal pairs in the width direction in a case 33 that is formed long in the width direction.
