Description of the Invention: [Technical Field of the Invention] The present invention relates to an electrical connector for a flat conductor. [Prior Art] As the flat conductor, a flexible substrate (FPC), a flat cable (FFC), or the like is known. Since the flat type conductor has tightly arranged wires, it is generally used for a multi-pole electrical connector mounted on a circuit board. The multi-pole electrical connector has terminals which are arranged in a direction perpendicular to the plate surface and which maintain the flat plate surface of the metal plate in order to closely arrange the terminals in correspondence with the flat-type conductor. As such a connector, a connector disclosed in Patent Document 1 is known. In the connector of Patent Document 1, the terminal formed by the above-mentioned board surface is composed of a signal terminal (signal contact) and a support terminal (support contact). The support terminal movably supports a movable member (operation member) for pressing the flat type conductor. In Patent Document 1, the signal terminal and the support terminal are formed in different shapes. The signal terminal is formed into a wrist-shaped member for high-speed signal transmission, and the contact portion that is in contact with the flat conductor and the connection portion that is soldered to the circuit board are connected in a substantially straight shape, and the protrusion is locked with the terminal groove of the casing. In addition, there is no protruding or extending portion between the contact portion and the connecting portion. Thereby, the influence of the stub of the local speed transmission of the G (GIGA) bps band can be reduced. On the other hand, the supporting terminal is a portion in which the contact portion and the connecting portion are formed, and is formed in the same shape as the signal terminal, and most of the other is formed in a shape different from the signal terminal -5 - 201203740. In other words, the signal terminal for forming the wrist member has a shape similar to that of the support terminal only in a limited portion such as the contact portion and the connection portion, and the entire wrist member has a completely different shape from the support terminal. In Patent Document 1, the terminal groove ′ of the casing for accommodating the terminals is also formed in a different shape corresponding to the signal terminal and the support terminal. [Prior Art] [Patent Document 1] [Patent Document 1] JP-A-2009-266440 [Problem to be Solved by the Invention] However, in Patent Document 1, the signal terminal and the support terminal have different shapes, and Since the terminal groove for accommodating it also has a different shape corresponding thereto, the signal terminal and the support terminal cannot correspond to the change in mutual position due to design change. In this type of connector, not only the signal terminals but also the ground terminals are usually arranged. In Patent Document 1, the support terminal can be used as a ground terminal. In this case, there is a great possibility that the position of the support terminal used as the ground terminal needs to be changed. However, Patent Document 1 cannot respond to this demand. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the invention to provide an electrical connector for a flat conductor which maintains the shape of a signal terminal capable of high-speed signal transmission and which can be changed in position from the support terminal. 201203740 [Means for Solving the Problem] In the electrical connector for a flat conductor of the present invention, the signal terminal and the support terminal have a contact portion for contacting a flat conductor inserted forward toward the housing portion of the housing, The signal terminal and the support terminal are formed by maintaining a flat plate surface of the metal plate and are inserted into the terminal groove of the housing at a right angle to the plate surface. The direction is aligned.

In the present invention of such a configuration, the signal terminal has its contact portion and the connecting portion which are disposed in front and rear on the wrist member, so that the signal is linear and transmitted at a short distance, and can also be transmitted at a high speed. On the other hand, the 'support terminal' is formed in the contact portion and the connection portion by connecting the wrist portion and the support arm portion by the connection portion, except that the same contact portion of the 201203740 contact portion and the connection portion is formed with the signal terminal. The current can be energized, and the movable member can be movably supported by the support portion formed on the support arm. Further, the wrist portion of the signal terminal and the support terminal for forming the wrist member is provided with a fixed portion, and is fixed to a fixing portion of the terminal groove of the casing, and the terminal groove can also be used for the signal terminal and the support terminal. One of the two terminals can be arbitrarily selected to determine the arrangement position, and the position of the two terminals can be changed without changing the mold of the casing. In the present invention, the support terminal can be energized between the contact portion and the connection portion, so Can be used as a ground terminal or power terminal. And the 'signal terminal is suitable for high-speed transmission. In contrast, if the support terminal is used for low-speed signal transmission, it can also be used as a signal terminal. In the present invention, the terminal groove of the casing is formed between the upper wall and the lower wall of the casing, and an island block-shaped fixing portion is provided in the terminal groove, and the fixed portion of the signal terminal or the support terminal can be pressed into Fixed between the fixed portion and the lower wall. Therefore, in this case, the signal terminal 'the wrist member is formed between the fixed portion and the lower wall of the island block in the terminal groove, and the wrist portion of the opposite 'support terminal exists in the island-shaped fixing portion and Between the lower walls 'and the support wrist exists between the fixed portion and the upper wall. [Effect of the Invention] In the present invention, as described above, the signal terminal is formed as a wrist member provided with a fixed portion, and the support terminal has a support arm for supporting the movable member -8 - 201203740 except for the wrist portion. And the terminal groove is made the same 'so that the high-speed signal transmission characteristic of the signal terminal can be ensured', and even for which terminal groove, the signal terminal and the support terminal can be selectively inserted into the mold without changing the casing, and a connection can be provided. The terminal arrangement can correspond to the requirements of use.

The housing 1 1 integrally includes: a side wall 12 at both ends in the direction in which the terminals are arranged, a lower wall 13 connecting the side walls 12 at the lower portion thereof, a front wall I4 at the front, and the front side The upper wall 15 on the wall 14 is formed with an opening portion 16 that is open upward and rearward between the two side walls 1 2 above the lower wall 13 . The opening portion 16 serves as an accommodating portion for inserting a flat conductor F to be described later, and functions as a space in which the movable member 50 is disposed and movable, and the casing 1 is along the inner surface of the side wall 1 2 . 'There is a support groove 70' for the fixing fitting 40 made of a metal plate, to which the fixing fitting 40 is attached. The fixing fitting 40' extends slightly from the bottom surface of the casing 1' to be welded to a corresponding portion of a circuit board (not shown) to facilitate the fixing of the casing 11 between the two supporting grooves 17' A plurality of terminal grooves 18 for receiving terminals are formed. The terminal ' is composed of two types of signal terminals 20 and a support terminal 30 which will be described later, and both of them are formed by maintaining a flat plate surface of the metal plate, so that the terminal groove 18 is also a slit shape suitable for the thickness thereof. The ditch. As shown in Fig. 3, the terminal groove 8 is formed so as to penetrate in a direction perpendicular to the plane of the paper, and a groove width corresponding to the thickness of the terminal is formed in the front-rear direction (the left-right direction in Fig. 3). The terminal groove 18' is interposed between the wall 15 and the lower wall 13 of the casing -10-201203740, and penetrates the front wall 14 forward and backward, and covers the upper surface of the lower wall 13 at the rear portion where the opening portion 16 is formed. In the terminal groove 18, an island-shaped fixing portion 19 is provided between the upper wall 15 and the lower wall 13 in the vertical direction of the rear portion of the front wall 14, and the terminal groove 18 is divided into: relative to the fixing portion. The upper region 18A on the upper side, the lower region 18B on the lower side, the connection region 18C that connects the two regions on the front side, and the open region 18D formed in the portion of the lower wall 13 corresponding to the opening 16 in the front-rear direction. The upper region 18A, the lower region 18B, the connection region 18C, and the open region 18D communicate with each other. In the terminal groove 18, the groove bottom of the open region 18D is a lower level located below the groove bottom of the lower portion 18B. Thereby, the downward displacement of the contact portions 22 and 32 of the terminals 20 and 30 to be described later is allowed, and when the solder connection of the terminals is formed, even if the flux rises, the flux can be prevented from reaching the contact portion. gap. The terminal groove 18 thus formed is formed into the same shape as the terminal groove of the signal terminal 20 and the terminal groove inserted into the support terminal 30 as shown in Figs. 4(A) and 4(B). Thus, even for which terminal groove 18, both the signal terminal 20 and the support terminal 30 can be selectively inserted. The signal terminal 20 formed by maintaining the flat plate surface of the metal plate is formed as a wrist-shaped member extending forward and backward as shown in FIG. 4(B), and has a connecting portion 21 at the front end portion and a contact portion at the rear end portion. 22, and has a projection 23 as a fixed portion at the intermediate portion. The connecting portion 21 is formed as a portion that protrudes outward from the casing 11 and is bent downward. The lower edge of the connecting portion 21 is located below the bottom surface of the casing 11 and is disposed on a circuit board (not shown). 'Weld the joint for the corresponding part. The signal terminal 20 extends toward the rear -11 - 201203740 to the intermediate portion of the casing 11, and the contact portion 22 is disposed to protrude upward at the rear end thereof. The projection 23 as the fixed portion is formed at two positions on the upper edge of the intermediate portion. The signal terminal 20 thus formed is pressed between the island-shaped fixing portion 19 and the lower wall 13 of the terminal groove 18 of the casing 11. The projection 23 bites into the lower edge of the fixing portion 19 to determine a fixed position. The rear portion of the signal terminal 20 protrudes rearward from the front wall 14 of the casing 11, and a gap is formed between the lower edge and the groove bottom of the terminal groove 18, and is elastically deflected downward. That is, when the contact portion 22 receives a downward force from the flat type conductor F, the contact portion 22 can be elastically displaced downward. The signal terminal 20 is provided with a small-shaped pressed portion 24 that protrudes upward on the distal end side, and the leading edge of the signal terminal 20 is pressed rearward when the terminal is inserted, and the rear edge of the pressed portion 24 abuts against the fixing portion 19 The front side of the signal terminal 20 is inserted into the terminal groove 18. When the trailing edge of the pressed portion 24 abuts against the front surface of the fixed portion 19, when the contact portion 22 is displaced downward by the force fl, the connection portion 2 1 side can be prevented from floating and displaced. On the other hand, as shown in FIG. 4(A), the support terminal 30 maintains the flat plate surface of the metal plate in the same manner as the signal terminal 20, except for the wrist portion 30A having the same shape as the signal terminal 20. The support arm 35 is connected to the distal end of the arm portion 30A by a connecting portion 34. The wrist portion 30A has the same shape as the signal terminal 20, and has a connecting portion 31 at the distal end, a contact portion 32 at the rear end, and a projection 33 as a fixed portion at the intermediate portion. The wrist portion 30A is elastically deflectable at the rear portion, the contact portion 32 is elastically displaceable, and the signal terminal 20 is also the same. The connecting portion 34 of the support terminal 30 is located on the right side of the island-shaped -12-201203740 fixing portion 19 of the casing 11, and extends upward from the front end of the arm portion 30A. The support arm portion 35 extends rearward from the upper end of the coupling portion 34. The support arm portion 35 extends rearward between the fixed portion 19 and the upper wall 15, and has a concavely curved support portion 36 at the lower edge of the rear end. The support arm portion 35 has a wider width (a size in the vertical direction in the drawing) than the above-described wrist portion 300A, and is made high in rigidity. When the support terminal 30 is inserted into the terminal groove 18 from the front toward the rear, the arm portion 30A is pressed into the island-like fixing portion 19 and the lower wall 13 in the same manner as the signal terminal 20, and the support wrist is supported. The portion 35 is fixed between the fixing portion 19 and the upper wall 15. In the present embodiment, the signal terminal 20 and the support terminal 30 are arranged such that one of the support terminals 30 is adjacent to the two signal terminals 20, and the support terminal 30 is used as a ground terminal for the signal terminal 20. The movable member 50 is made of the same electrically insulating material as that of the casing 11, and has a width covering the terminal arrangement range as shown in Figs. 1 and 2, and is disposed in the opening portion 16 of the casing 11. The movable member 50 is movably supported between the open position and the closed position as described above, and the groove portion 51 is formed in the lower portion at the open position shown in Figs. 4(A) and 4(B). The groove portion 51 is formed at a position corresponding to the terminal groove 18 for the signal terminal 20 and the support terminal 30 in the terminal arrangement direction, and is inserted forward and backward. At the lower end position, the groove portion 51 is connected to the inner surface of the groove. Shaft portion 52. The shaft portion 52 has a substantially circular peripheral surface, and is supported by the support portion 36 which is formed in a concavely curved shape at the support arm portion 35 of the support terminal 30 so as to be rotatable freely. However, the signal terminal 20 does not have the support arm as described above, and the -13-201203740 does not have any support at the shaft portion 52 at the position corresponding to the signal terminal 20. The movable member 50 is rotatably supported by the housing at both ends in the width direction (terminal arrangement direction) by a shaft portion (not shown). In the movable member 50, the operation portion 53 is formed on the upper portion where the groove portion 51 is not formed in the fourth drawing (A) and (B), and protrudes upward from the upper wall 15 of the casing 11. The movable member 50 is rotationally moved between the open position and the closed position by the operating portion 53 by the operating force. The movable member 50 is formed with a pressurizing portion for pressing the flat conductor F at the closed position from the lower end portion of Figs. 4(A) and (B) to the rear surface (left side) of the operation portion 53. The connector 1 of the present embodiment is used by being mounted on a circuit board (not shown). The signal terminal 20 and the support terminal 30 are connected to the connection portion 31 and the corresponding circuit portion of the circuit board by the connection portion 31. Further, the fixing fitting 40 is also welded to the circuit board with its fixing portion. The connector 1 is connected and fixed to the circuit board. When in use, the movable member 50 is brought to the open position as shown in Figs. 4(A) and (B), and the opening portion 16 of the casing 1 1 is largely opened toward the rear, and the opening portion 16 is turned toward the opening portion 16 The front end portion of the flat conductor F shown in Fig. 1 is inserted. In the fourth (A) and (B) 'flat conductor F, the contact portion 22 of the signal terminal 20 and the contact portion 32 of the support terminal 30 and the movable member 50 at the open position are inserted forward. The front end edge of the flat type conductor F abuts against the rear side of the front wall I4 of the casing 11 and is brought to a predetermined insertion position. The connection conductor portion exposed at the predetermined insertion position 'below the lower surface of the flat conductor F is located at the contact portion 22 of the corresponding signal terminal 20 and the contact portion 32 of the support terminal -14 - 201203740 30. Then, an operating force is applied to the operating portion 53 of the movable member 50, and the movable member 50 is rotationally moved toward the closed position shown in Figs. 5(A) and (B). The movable member 50 presses the flat conductor F downward with its pressing portion. The flat conductor F pressed by the movable member 50 presses the contact portion 22 of the signal terminal 20 and the contact portion 32 of the support terminal 30 downward to be elastically displaced. The contact portion 22 and the contact portion 32 electrically connect the signal terminal 20 and the support terminal 30 to the corresponding connection conductor portion of the flat conductor F by contact pressure (contact force). The support terminal 30 functions as a ground terminal when the corresponding connecting conductor portion of the flat conductor F and the corresponding circuit portion of the circuit board are grounded circuits. The arrangement of the terminals 20, 30 can be freely set in various ways. When the signal terminal 20 is S, the ground terminal formed by the support terminal 30 is G, the low-speed signal terminal is L, and the power terminal is D, it can constitute: ... the differential signal arrangement of GSSGSSG..., ....GSSGLGDDD...the composite arrangement, ...GSSSSSGSSSSSG...the arrangement of the grounding terminals is small. In the present invention, the signal terminal 20 is formed as a linear wrist member. Therefore, a transmission path is formed between the contact portion 22 and the connection portion 21 with a linear shortest distance, and a portion where the circuit line is not formed is formed, so that the influence of a stub is reduced, the signal is transmitted at a high speed, and the support terminal 30 can also be As the grounding terminal, the supporting terminal 30 is located between the signal terminals 20 and has a shielding effect. In the present embodiment, the wrist portion 30A of the support terminal 30 has substantially the same shape as the signal terminal 2〇, and the terminal groove 18 has a common shape -15-201203740 for the two terminals 20 and 30, so that any terminal groove can be selectively inserted. 'The terminal arrangement has a degree of freedom. Further, if the signal terminal 20 and the wrist portion of the support terminal (ground terminal) 30 have the same shape, the contact pressure at the contact portion is all the same, and a stable contact force can be obtained. In the present embodiment, the support terminal 30 can be used not only as the ground terminal but also as a signal terminal or a power supply terminal depending on the demand. When the signal terminal is used, the support arm 35 is present between the contact portion 32 and the connection portion 31 via the connection portion 34, so that it is preferably used as a low-speed signal that does not affect the transmission speed. The present invention can be variously modified in addition to the above-described pictorial form. For example, the signal terminal 20 needs to be connected to a desired straight line between the contact portion 22 and the connecting portion 21, and it is preferable to reduce the protruding small portion as much as possible. As an example, as shown in Fig. 6(A), the pressed portion 24 for press-fitting of the signal terminal 20 is formed in a triangular shape to minimize the signal returning area at the time of signal transmission and to receive the pressing force at the leading edge 24A. Further, as shown in Fig. 6(B)', the small portion for the pressed portion is not provided, and the leading edge of the connecting portion 21 may be the pressed portion 24A.
