In the flat connector electrical connector, in the present invention, at least a part of the plurality of terminals has an upper arm portion and a lower arm portion extending in the front-rear direction, and the front end portion of the upper arm portion and the lower arm portion are connected to each other. The connecting portion is formed with a lateral U-shaped portion that opens toward the rear by the upper arm portion, the lower arm portion, and the connecting portion, and the horizontal U-shaped portion receives the flat conductor and is elastically displaced, so that the upper wrist portion and the upper wrist portion can be The aforementioned lower wrist pinches the flat conductor, In the housing, at least the entire range of the terminals is arranged in the arrangement direction, and at least the entire upper arm portion of the terminal in the front-rear direction is formed with a space that opens upward, and the space serves as the movable portion for accommodating the closed position. An accommodating portion of at least a part of the member, wherein the accommodating portion communicates with the receiving portion above the receiving portion, and the movable member is elastically movable in the vertical direction at the closed position at an outer position of the arrangement range of the terminals in the arranging direction a locking wrist portion that is displaced, and a locking portion that protrudes downward is formed in the locking arm portion, and is formed at a position corresponding to each terminal in the terminal arrangement range in the arrangement direction a groove portion for receiving a part of the upper wrist portion of the terminal, When the movable member is positioned at the closed position, when the flat conductor is inserted into the receiving portion, the front end of the flat conductor abuts against the locking portion, and the locking arm portion is elastically displaced upward to allow the aforementioned In a state in which the insertion of the flat-type conductor into the predetermined position is completed, the locking arm portion is displaced downward to reduce the amount of elastic displacement, and the held portion formed at both side ends of the flat-type conductor is held. When the locking member is locked, the flat conductor is prevented from being pulled out rearward, and when the movable member is located at the open position, the locking portion is released from the locked portion, and the flat conductor is allowed to face. Pull out at the rear.

Therefore, the movable member is not positioned above the casing but entirely in the accommodating portion, and this portion can make the size of the connector in the up and down direction small.

Further, the movable member is formed with a groove portion for accommodating a part of the terminal, and the inward wall surface of the groove portion restricts inadvertent displacement of the terminal in the terminal arrangement direction. Since the groove portion is formed in the movable member, it is not necessary to provide another member for the purpose of the restriction. Therefore, the connector is not enlarged in the vertical direction, which contributes to downsizing of the connector.

In the present invention, the following structure may also be used, that is, having a horizontal U In the terminal portion of the word portion, the strip-shaped metal plate having the width direction of the terminal is bent in the thickness direction to form the horizontal U-shaped portion, and the width of the upper arm portion is smaller than that of the lower wrist portion.

In such a configuration, the flat type conductor is pressed by the upper arm portion and the lower arm portion of the terminal, and the upper arm portion is biased upward (referred to as an upper pressing force) as a flat member. The reaction force of the type conductor also acts on the lower wrist portion to have a downward pressing force (referred to as a lower pressing force) of the same magnitude as the above-mentioned upper pressing force. In the present invention, the width of the upper wrist portion is smaller than that of the lower wrist portion, and the upper wrist portion having a narrow width is lower in rigidity than the lower wrist portion and is easily deflected. Therefore, in the present invention, the upper pressing force required to displace the upper wrist portion by a predetermined amount is smaller than the case where the upper wrist portion is formed in the same width direction as the lower wrist portion. Further, as described above, in the lower wrist portion, there is a pressing force acting under the same magnitude as the upper pressing force acting on the upper wrist portion. In the present invention, the width dimension of the lower wrist portion is larger than that of the upper wrist portion, and the rigidity is high and the deflection is not easy. The lower pressing force acting on the lower arm portion can be set to be smaller than the above-described upper pressing force as described above. Therefore, the elastic force of the lower wrist portion is formed by the same width as the upper wrist portion and the lower wrist portion. The amount of displacement becomes smaller. In other words, since the amount of elastic displacement in the lower arm portion is small, the elastic displacement in the vertical direction as the entire terminal is also reduced in this portion. Therefore, the space for allowing the elastic displacement can be reduced in the vertical direction, and the casing can be further Seeking the shortness of the connector.

In the present invention, a configuration may be adopted in which a plurality of terminals are formed by buckling a strip-shaped metal plate in a thickness direction, and the plurality of ends are formed. A part of the terminals is a terminal having a lateral U-shaped portion, and the other terminals have a position extending in the vertical direction from the above-mentioned part of the terminal over the wrist, and are elastically displaceable in the up and down direction. a part of the wrist portion is housed in a groove portion of the movable member, and a part of the terminal and the other terminal are located at an upper wrist portion of the terminal of the part and a wrist portion of the other terminal are overlapped In the state of the front and rear direction, they are arranged alternately.

In this aspect, the terminal having a lateral U-shaped portion of the terminal of the plurality of terminals is smaller than the lower wrist portion, and the width of the upper arm portion is small. Therefore, the terminals adjacent to each other are adjacent to each other. There is a gap between the upper wrists. Further, the wrist portion of the other terminal is positioned in the vertical direction and the front-rear direction so as to have a range overlapping with the wrist portion of the terminal. That is, the wrist portions of the other terminals are the aforementioned gaps between the wrist portions on the terminal portions of the aforementioned portions. As described above, by providing the wrist portion of the other terminal in the vertical direction and having a position overlapping with the wrist portion of the terminal portion, it is possible to avoid an increase in size of the connector in the vertical direction. Further, the width of the upper wrist portion is smaller than that of the lower wrist portion, which means that the gap between the upper wrist portions is larger than the gap between the lower wrist portions. According to the present invention, the wrist portion of the other terminal is placed in the gap by using a large gap between the wrist portions on the terminal of the terminal portion, and the size of the connector can be avoided even in the terminal array direction. Further, not only a part of the terminals but also one of the other terminals is accommodated in the groove portion of the movable member, and the inward wall surface of the groove portion can restrict the inadvertent displacement of the terminal in the terminal arrangement direction.

As described above, according to the present invention, since at least a part of the movable member in the closed position is housed in the accommodating portion of the casing, the portion can be reduced in the vertical direction of the connector, and the connector can be obtained. Short stature. Further, since the groove portion for accommodating a part of the terminal is formed in the movable member, the connector is not enlarged in the vertical direction, and the inadvertent displacement of the terminal in the terminal arrangement direction can be restricted.

The receiving groove portion 41A for accommodating the restricted portions 21B and 31B of the upper arm portions 21 and 31 of the terminals 20 and 30 is formed at a position corresponding to each of the terminals 20 and 30 (see FIGS. 6(A) and (B)). In this manner, the restricted portions 21B and 31B are housed in the accommodating groove portion 41A, and the opposing inner wall surface (the surface at right angles to the arrangement direction) of the groove portion 41A is accommodated, and the restricted portions 21B and 31B in the arrangement direction are restricted. The inadvertent displacement, in turn, limits the inadvertent displacement of the upper wrists 21, 31. In the present embodiment, since the accommodating groove portion 41A is provided in the vicinity of the region of the shaft portion 46 to be described later, the restricted portion 21B, 31B is located at any position within the range of movement of the movable member 40 from the closed position to the open position. At least a part of the accommodated groove portion 41A is also accommodated, so that the displacement of the restricted portions 21B and 31B can always be restricted. Moreover, since the accommodating groove portion 41A is formed in the movable member 40, it is not necessary to provide another member for the purpose of the restriction, and therefore, the connector 1 is not enlarged in the vertical direction.

As shown in FIG. 4, the main body portion 41 is attached to the upper end side portion (the end side portion before the closed position shown in FIGS. 6(A) and (B)), and has a front side (closed). The lower portion of the closed position protrudes, and extends in the terminal arrangement direction over the wall portion 41B of the entire terminal arrangement range. The wall portion 41B is formed with the immersion portion 41B-1 in a substantially entire region of the terminal arrangement direction by the front half portion (the front lower half portion at the closed position), so that the rear half portion, that is, the portion that is not immersed is formed as an operation. Part 41B-2. Further, by hooking the finger to the operation portion 41B-2, the movable member 40 is rotated toward the open position.

Further, the end arm portion 42 is bent into a crank shape when viewed in the terminal arrangement direction, and the lower half portion is located further forward than the upper half portion (below the closed position).

As shown in FIG. 4, the locking arm portion 44 is formed with a locking portion 44A that protrudes toward the front (below the closed position) as a lower end portion of the free end. As shown in FIG. 6(C), the locking portion 44A protrudes from the upper side into the receiving portion 19A of the casing 10 when the movable member 40 is in the closed position, and abuts or approaches the upper surface of the side surface portion 14. Further, as shown in Fig. 6(C), the rear end surface of the locking portion 44A is formed with an inclined surface 44A-1 which is inclined downward toward the front, and the ear portion C2 of the flat type conductor C during insertion. When the front end portion abuts against the inclined surface 44A-1, the locking arm portion 44 is easily elastically displaced upward. Further, the front end surface of the locking portion 44A is formed as a locking surface 44A-2 which is perpendicular to the front-rear direction, and the locking surface 44A-2 is surely locked to the locked portion C2A of the flat conductor C. The flat conductor C is inadvertently pulled out.

As shown in FIGS. 3 and 4, the joint portion 43 is attached to the upper end portion. (the end side portion before the closed position shown in FIGS. 6(A) and (B)) has a front side (lower side of the closed position) and has the same height as the upper surface of the operation portion 41B-2 of the main body portion 41. Wall portion 43A. The locked portion 45 is formed so as to protrude outward in the terminal arrangement direction from the side end position of the side end surface of the wall portion 43A (the position near the lower end of the closed position). When the movable member 40 is in the closed position, the locked portion 45 can be locked by the locking portion 15B positioned below the locking portion 15B of the casing 10, preventing the movable member 40 from inadvertently rotating toward the open position. In the present embodiment, the locked portion 45 is provided at both side ends of the movable member 40. However, the position of the locked portion is not limited thereto, and may be provided, for example, at the upper end of the movable member 40 in Figs. Position before the end).

The shaft portion 46 has a semicircular shape in a cross-sectional shape that is perpendicular to the arrangement direction. As shown in FIG. 1, when the movable member 40 is at the closed position, the arc portion is convexly curved toward the front. The shaft portion 46 extends from the lower side of the both side ends of the main body portion 41 toward the outside in the terminal arrangement direction, and reaches the outer side of the opposite end portion 42. Therefore, as shown in FIGS. 3 and 4, the shaft portion 46 has its free end side portion projecting outward from the outer side surface of the end arm portion 42. The free end side portion is located at a position corresponding to the support hole portion 15A of the side wall 15 of the casing 10 in the terminal arrangement direction, and is provided as a support portion 46A rotatably supported by the support hole portion 15A. Features. Further, the shaft portion 46 is in the terminal arrangement direction, and the portion between the end arm portion 42 and the locking arm portion 44 is located at a position corresponding to the support concave portion 17B of the side surface regulating portion 17 of the casing 10 as a The intermediate supported portion 46B that is rotatably supported by the support recess 17B functions.

The movable member 40 having such a structure is mounted in the following manner. First, the movable member 40 is made to enter between the two side walls 15 of the casing 10 from above. At this time, the two side walls 15 of the casing 10 are pushed away from each other by the front end of the shaft portion 46 of the movable member 40. In addition, while the outer side portion of the side frame portion 10C of the casing 10 is elastically displaced outward in the terminal arrangement direction with the fulcrum portion 10C-1 as a fulcrum, the end of the shaft portion 46 is guided from the inside to the casing by the support portion 46A. The side wall 15 of the support hole 15 of the 10 is supported, and the intermediate portion of the shaft portion 46 is supported by the support portion 46B from above into the support recess portion 17B of the side surface restriction portion 17 of the casing 10. Then, the movable member 40 is attached to the casing 10 by returning the aforementioned outer portion to a free state.

As shown in FIG. 1, when the movable member 40 is in the closed position, the main body portion 41 and the locking arm portion 44 of the movable member 40 are housed in the body housing portion 19B of the housing 10 (refer to FIGS. 3 and 4), and are movable. The end arm portion 42 of the member 40 is housed in the end wrist receiving portion 19B-2 (see FIGS. 3 and 4) of the casing 10. As shown in Fig. 1, the movable member 40 is at the closed position, and substantially all of the vertical direction is accommodated in the accommodating portion 19B, and this portion can reduce the vertical dimension of the connector 1 (see also Figs. 6(A) to (C). )). Moreover, since the movable member 40 covers the terminal arrangement range in the closed position, dust, dust, and the like can be prevented from adhering to the terminals 20 and 30. In the present embodiment, substantially all of the movable member 40 in the vertical direction is housed in the accommodating portion 19B. However, instead of this configuration, a part of the movable member in the vertical direction may be accommodated in the accommodating portion, and the accommodated portion may be reduced. The size of the connector 1 in the up and down direction.

The fixing fastener 50 is held by the side base portion 14 of the casing 10 at a position close to both ends of the casing 10 in the terminal arrangement direction and in the front-rear direction. The fixing fastener 50 is produced by bending a strip-shaped metal plate having a terminal arrangement direction as a width direction in the thickness direction, and has a holding portion (not shown) held by the casing 10 and a corresponding portion welded to the circuit board. The fixing portion 51. The held portion is integrally molded with the side base portion 14 of the casing 10 and held by the side base portion 14. The lower surface of the fixing fastener 50 extends rearward and is located below the lower surface of the side surface base portion 14 and is welded to the circuit portion of the circuit board. This soldering facilitates the fixing of the connector 1 to the circuit substrate.

Next, the connection operation between the connector 1 and the flat type conductor C will be described with reference to Figs. 6 to 8 are cross-sectional views of the connector 1 having a plane at right angles to the arrangement direction, showing a state before the flat conductor C is inserted, a state after the flat conductor C is inserted, and a flat conductor C to be pulled out. The state before going out. Further, in each of the drawings, (A) shows a cross section of the position of the first terminal 20, (B) shows a cross section of the position of the second terminal 30, and (C) shows the position of the locking arm portion 44 of the movable member 40. Section.

First, the connecting portions 24, 34 of the terminals 20, 30 of the connector 1 are soldered to the corresponding circuit portions of the circuit board, and the fixing portions 51 of the fixing fasteners are soldered to the corresponding portions of the circuit board. Since the outer side portion of the side frame portion 10C of the casing 10 is fixed to the circuit board by the welding of the fixing portion 51, the elastic displacement of the outer portion with the fulcrum portion 10C-1 as a fulcrum is restricted. As a result, the movable member 40 can be prevented from being detached from the casing 10.

Next, as shown in FIGS. 6(A) to (C), the movable member 40 is brought to the closed position, and the flat conductor C is placed rearward of the connector 1 so as to extend in the front-rear direction along the surface of the circuit board. . Next, the flat conductor C is inserted into the receiving portion 19A of the connector 1 forward. When this insertion is performed, the flat type conductor C is guided to the receiving surface 19A of the casing 10 and the guiding surface 16A toward the receiving portion 19A. Moreover, the flat conductor C inserted into the receiving portion 19A is positioned in the width direction by the side surface regulating surface 17A (see FIGS. 3 and 4) of the side surface regulating portion 17 of the casing 10. Further, the flat conductor C is positioned in the front-rear direction by the front regulating surface 18A of the front regulating portion 18 of the casing 10. Therefore, in the present embodiment, the flat conductor C can be easily brought to a predetermined normal position only by inserting the flat conductor C into the receiving portion 19A.

During the insertion of the flat conductor C into the receiving portion 19A, the flat conductor C enters the transverse U-shaped portion of the first terminal 20, and the transverse U-shaped portion is elastically displaced. Specifically, the flat conductor C pushes up the contact convex portion 21A by abutting against the contact convex portion 21A of the upper arm portion 21 of the first terminal 20 and abuts against the lower arm portion 22 of the first terminal 20 . The support protrusion 22A is pressed to press the support protrusion 22A, the upper arm 21 is elastically displaced upward, and the lower arm 22 is elastically displaced downward, thereby pushing the upper arm 21 and the lower arm 22 upward. . As a result, as shown in FIG. 7(A), in the state in which the insertion of the flat conductor C is completed, the flat conductor C is supported by the contact convex portion 21A of the upper arm portion 21 and the support convex portion 22A of the lower arm portion 22. The circuit portion (not shown) exposed on the upper surface of the flat conductor C and the upper arm portion 21 are sandwiched in the vertical direction. The contact protrusion 21A is in contact with the contact pressure.

In the present embodiment, the contact convex portion 21A of the upper arm portion 21 is located further rearward than the support convex portion 22A of the lower arm portion 22, and the length of the upper wrist portion 21 from the base portion (portion connected to the joint portion 23) to the contact convex portion 21A is The length of the lower wrist portion from the base portion to the support convex portion 22A is large. Therefore, in a state where the flat conductor C is inserted between the upper arm portion 21 and the lower arm portion 22, the elastic displacement amount of the upper arm portion 21 is larger than that of the lower wrist portion.

In the present embodiment, the upper arm portion 21 of the first terminal 20 has a smaller dimension in the width direction than the lower arm portion 22. The rigidity of the upper arm portion 21 having a narrow width is lower than that of the lower arm portion 22 and is easily deflected. Therefore, in the present embodiment, the upper pressing force (the upward pressing force) required to displace the upper arm portion 21 upward by a predetermined amount is smaller than the case where the upper arm portion is formed in the same width direction as the lower arm portion. Achievable. In addition, as a reaction force from the flat conductor, the lower pressing portion 22 acts on the lower pressing portion 22 (the downward pressing force) of the same magnitude as the upper pressing force acting on the upper arm portion 21. In the present embodiment, the size of the lower arm portion 22 in the width direction is larger than that of the upper arm portion 21, and the rigidity is high and it is not easily deflected. The lower pressing force acting on the lower arm portion 22 can be set to be smaller than the above-described upper pressing force as described above. Therefore, the lower wrist portion is formed by the same width as the upper wrist portion 21 and the lower wrist portion 22. The amount of elastic displacement of 22 becomes smaller. In other words, since the amount of elastic displacement of the lower arm portion 22 is small, the elastic displacement of the entire first terminal 20 in the vertical direction is also reduced, so that the space for allowing the elastic displacement can be reduced in the vertical direction. The casing 10 is further required to shorten the connector 1 .

Further, during the insertion of the flat conductor C into the receiving portion 19A, the flat conductor C is pushed up by the contact convex portion 31A of the upper arm portion 31 of the second terminal 30, and the contact convex portion 31A is pushed up. The upper wrist portion 31 is elastically displaced upward. As a result, as shown in FIG. 7(B), in the state in which the insertion of the flat conductor C is completed, the contact portion 31A of the circuit portion (not shown) exposed on the upper surface of the flat conductor C and the upper arm portion 31 is Contact pressure contact.

Further, during the insertion of the flat conductor C toward the receiving portion 19A, the ear portion C2 located at a position close to both sides of the flat type conductor C abuts against the rear end card formed on the locking arm portion 44 of the movable member 40. The inclined surface 44A-1 of the stopper portion 44A elastically displaces the locking arm portion 44 upward to a position where the flat conductor C is allowed to be inserted. When the flat type conductor C is inserted and the ear portion C2 passes the position of the locking portion 44A, the locking arm portion 44 is displaced downward to reduce the amount of elastic displacement, and returns to the free state, and protrudes into the notch portion C1 of the flat conductor C. As a result, as shown in FIG. 7(C), in the state where the insertion of the flat conductor C is completed, the locked portion C2A of the flat conductor C is located at the locking surface 44A-2 of the locking portion 44A. Position, therefore, the flat type conductor C is prevented from being pulled out toward the rear. Furthermore, the locking wrist 44 does not need to be completely returned to a free state. For example, in a state in which a certain amount of elastic displacement remains in the locking arm portion 44, the locking portion 44A protrudes into the notch portion C1 of the flat type conductor C and is located at the engageable portion C2A. The position of the lock is set, and the ear portion C2 of the flat type conductor C is sandwiched in the up-and-down direction by the aforementioned locking arm portion 44 and the side surface base portion 14.

When the flat conductor C in the state shown in FIGS. 7(A) to (C), that is, the state in which the connector 1 is connected, is pulled out from the connector 1, the movable member 40 positioned in the closed position is rotated to come. The open position shown in Figs. 8(A) to (C). As shown in FIG. 8(C), when the movable member 40 is in the open position, the locking portion 44A of the locking arm portion 44 is located outside the notch portion C1 of the flat type conductor C. In other words, the locked state of the locked portion C2A of the flat conductor C by the locking portion 44A is released, and the flat conductor C is allowed to be pulled rearward. Then, when the flat conductor C is pulled rearward in this state, the flat conductor C can be easily pulled out.

In the present embodiment, the casing 10 has two side walls 15, but the side walls are not necessarily required. When the casing is not provided with a side wall, the space of the movable member 40 disposed at the closed position above the receiving portion can function as the accommodating portion.

In the present embodiment, the first terminal 20 and the second terminal 30, which are two types of terminals, are provided, but the number of types of terminals is not limited to this. For example, only one of the first terminal 20 and the second terminal 30 may be provided.

Further, in the present embodiment, the first terminal 20 is provided with the contact convex portion 21A for electrically connecting the flat conductor C to the upper arm portion 21, but the position of the contact convex portion is a circuit that can fit the flat type conductor C. The location of the department is subject to change. For example, when the circuit portion is exposed to the lower surface, a contact convex portion may be provided on the lower wrist portion instead of the upper wrist portion, and the contact portion may be provided on both the upper wrist portion and the lower wrist portion when the circuit portion is exposed on the upper surface and the lower surface portion. unit.

In the present embodiment, as shown in FIGS. 6(A) and 6(B), the wall portion 41B of the movable member 40 at the closed position is substantially at the same position as the connection portion 34 of the second terminal 30 in the front-rear direction, but In place of this configuration, the wall portion of the movable member may be located forward of the connection portion of the second terminal in the front-rear direction, and the lower end of the wall portion may extend to the vicinity of the mounting surface of the circuit board in the up-and-down direction. s position. Thereby, since the connection portion of the second terminal can be covered by the wall portion, it is possible to more reliably prevent dust or the like from adhering to the connection portion.
