FIG. 1 is a partial cross-sectional perspective view showing the overall configuration of a connector according to an embodiment of the present invention.

  The female connector according to this embodiment includes a resin female connector portion 10, a housing portion 12, and terminals 20. The female connector part 10 and the housing part 12 are integrally formed by molding. The terminal 20 includes four connection terminals 22, 24, 26, and 28. The terminal 20 is insert-molded so as to penetrate the female connector part 10 and to be partly exposed and embedded in the housing part 12.

  One end portions 22A, 24A, 26A, 28A of the connection terminals 22, 24, 26, 28 are located inside the female connector portion 10 and are electrically connected to a male connector (not shown). When viewed from the opening side of the female connector section 10, 22A, 24A, 26A, 28A are arranged in a quadrangular (rectangular or square) shape. That is, the line connecting 22A and the end 24A is parallel to the line connecting end 26A and the end 28A, and the line connecting 22A and end 26A is the line connecting the end 24A and end 28A. Are parallel.

  On the other hand, the housing part 12 has a circuit board (not shown) mounted therein. The other end 22B, 24B, 26B, 28B of the connection terminal 22, 24, 26, 28 is located in the housing part 12. As described above, the other end portions 22B, 24B, 26B, and 28B are embedded in the housing portion 12, and a part thereof is exposed from the housing portion 12. Therefore, the circuit is formed using this exposed portion. It is electrically connected to the terminal of the substrate by wire bonding. The other ends 22B, 24B, 26B, 28B are located on the same plane. In the illustrated state, the connection terminals 22, 24, 26, and 28 are integrated by the crosspiece 30. The connection terminals 22, 24, 26 and 28 are pressed together with the crosspiece 30.

  The connection terminals 22, 24, 26, and 28 are press-molded plate-like bodies. The connection terminals 26 and 28 have one end located on the same plane with respect to the plane in which the other end is arranged. One end of each of the connection terminals 22 and 24 is located on a plane different from the same plane with respect to the plane on which the other end is arranged.

  At the time of insert molding, after the connection terminals 22, 24, 26, 28 and the crosspiece 30 are integrated, they are arranged in the mold and are integrally molded with the female connector 10 and the housing 12 by insert molding. The crosspiece 30 is cut off from the notch 33. The pilot hole 32 is a hole for positioning during press working.

Next, the configuration of the terminals used in the connector according to the present embodiment will be described with reference to FIGS.
2 and 3 are perspective views showing the configuration of terminals used in the connector according to the embodiment of the present invention. The same reference numerals as those in FIG. 1 indicate the same parts.

  At the end of the press working, as shown in the figure, the connection terminals 22, 24, 26, 28 and the crosspiece 30 constituting the terminal 20 are integrated. Here, one end portions 22A, 24A, 26A, 28A and the other end portions 22B, 24B, 26B, 28B of the connection terminals 22, 24, 26, 28 respectively extend in the same direction. Let the direction be the X direction. Also, the directions orthogonal to the X direction are defined as the Y direction and the Z direction, respectively.

  First, of the four connection terminals 22, 24, 26, 28, the connection terminals 22, 24 positioned on the upper side when viewed from the opening side of the female connector section 10, have a crank-shaped bent portion 22 </ b> C, 24C. The crank-shaped bent portion 22C of the connection terminal 22 is bent at a right angle in the Y direction at the bent portion 22a from the state in which the other end portion 22B extends in the X direction, and further in the X direction at the bent portion 22b. And then continues to one end 22A. The crank-shaped bent portion 24C of the connection terminal 24 is bent at a right angle in the Y direction at the bent portion 24a from the state in which the other end portion 24B extends in the X direction, and further, in the X direction at the bent portion 24b. And then continues to one end 24A.

  On the other hand, of the four connection terminals 22, 24, 26, and 28, the connection terminals 26 and 28 positioned on the lower side when viewed from the opening side of the female connector portion 10 are in the middle of the composite bent portion 26D, 28D. Initially, the structure of the composite bending part 26D is demonstrated. The tip of the other end 26B of the connection terminal 26 has an L shape, and has a bent portion 26a bent at a right angle in the Y direction at the tip of the L shape. Furthermore, it has an L shape at its tip, and has a bent portion 26b that is bent at a right angle in the Z direction. On the other hand, the tip of one end portion 26A has a U shape, and has a bent portion 26c bent at a right angle in the Y direction at the tip of the U shape. That is, when viewed from one end portion 26A and the other end portion 26B, first, a bent portion 26b having bent portions 26c and 26a in the Y direction and bent in the Z direction between the bent portions 26c and 26a. And has a composite bent portion 26D having three bent portions 26a, 26b, and 26c.

  The configuration of the composite bent portion 28D will be described. The tip of the other end 28B of the connection terminal 28 has an L shape, and has a bent portion 28a bent at a right angle in the Y direction at the tip of the L shape. Furthermore, it has an L shape at its tip, and has a bent portion 28b bent at a right angle in the Z direction. On the other hand, the tip of one end portion 28A has a U shape, and has a bent portion 28c bent at a right angle in the Y direction at the tip of the U shape. That is, when viewed from one end portion 28A and the other end portion 28B, first, a bent portion 28b having bent portions 28c, 28a in the Y direction and bent in the Z direction between the bent portions 28c and 28a. And has a composite bent portion 28D having three bent portions 28a, 28b, 28c.

  That is, the connection terminals 26 and 28 are the same as the crosspieces 30 by bending the bent portions 26a, 26c, 28a, and 28c at a right angle upward in FIG. 2 and further bending the bent portions 26b and 28b at a right angle. It moves so as to rotate on the plane starting from the bent portions 26b and 28b, and is arranged below the connection terminals 22 and 24.

  As described above, one end 22A, 24A, 26A, 28A of the connection terminal 22, 24, 26, 28 is vertically formed even in the integrally formed terminal 20 by bending the connection terminals 22, 24, 26, 28. The other end portions 22B, 24B, 26B, and 28B can be arranged on a single plane.

  As shown in the figure, the connection terminals 22, 24, 26 and 28 are integrated by a crosspiece 30. Accordingly, the integrated connection terminals 22, 24, 26, 28 and the crosspiece 30 are handled as they are, and positioned in a mold, and then insert-molded. By forming the connector part 10 and the housing part 12, the female connector shown in FIG. 1 can be manufactured.
