Description

The present invention relates to an electric connector for a flat conductor to which a flat conductor is removably connected.

Such an electric connector is disclosed in Patent Document 1, for example. The electric connector of Patent Document 1 is mounted on a mounting surface of a circuit board, and a flat conductor is inserted and removed in the front-rear direction parallel to the mounting surface. The electric connector holds a plurality of terminals arranged in the connector width direction (a direction perpendicular to the front-rear direction and the same direction as the width direction of the flat conductor) and the plurality of terminals, and rearwardly. It has a housing in which a flat conductor is inserted into the opened receiving portion, and a movable member that can reciprocate and rotate in the contacting and separating directions with respect to the housing.

The movable member is located around a rotation axis extending in the connector width direction between a closed position extending in the front-rear direction when viewed in the connector width direction and an open position extending in the vertical direction (connector thickness direction). Is rotatable. The movable member is rotated in a direction close to the housing and brought to a closed position to prevent the flat conductor inserted into the housing from being pulled out at the closed position and to rotate in a direction away from the housing. It moves and is brought to the open position, which allows the flat conductor to be pulled out.

Two types of a plurality of terminals are provided, and the two types of terminals (first terminal and second terminal) have different shapes and are arranged alternately in the connector width direction. All types of terminals are made by bending a strip-shaped metal plate member in the plate thickness direction, and the connector width direction (terminal arrangement direction) is the terminal width direction. When viewed in the connector width direction, the first terminal has a substantially crank-shaped overall shape, and the second terminal has a substantially horizontal U-shape that opens rearward.

The first terminal and the second terminal each have a first contact arm portion and a second contact arm portion extending rearward, and the rear ends of the first contact arm portion and the second contact arm portion, respectively. The first contact portion and the second contact portion, which project downward, are bent and formed in the portion. The first contact portion and the second contact portion are formed at the same position in the front-rear direction, and come into contact with the flat conductor inserted in the housing with contact pressure from above.

The movable member has a rotation base portion that includes a rotation axis, and the rotation base portion is located at a position corresponding to each of the first contact arm portion and the second contact arm portion in the connector width direction. A housing groove is formed to accommodate the rear end of each contact arm.

In general, in an electric connector to which a flat conductor is connected, the rear end of the contact arm portion of the terminal is often located near the rear end opening of the receiving portion of the housing, and carelessly at the rear end of the contact arm portion. External force is easy to act. Therefore, it is desirable that the electric connector has a configuration capable of reliably regulating the displacement of the contact arm portion due to such an external force.

In Patent Document 1, as described above, since the rear ends of the first contact arm and the second contact arm are accommodated in the accommodating groove of the movable member, the partition walls separating the adjacent accommodating grooves are in contact with each other. It is positioned so that it can come into contact with the rear end of the arm portion in the connector width direction, and as a result, careless displacement of both contact arm portions in the connector width direction is restricted.

Patent No. 5651652

In an electric connector in which a plurality of terminals are arranged in the connector width direction as in Patent Document 1, the distance between adjacent terminals is often reduced in order to reduce the size of the connector in the connector width direction. In Patent Document 1, when the distance between the terminals is reduced, the wall thickness dimension (dimension in the connector width direction) of the partition wall of the movable member located corresponding to the gap in the connector width direction and separating the accommodating grooves is also reduced. .. As a result, sufficient strength cannot be ensured for the partition wall, the partition wall is easily deformed or damaged, and careless displacement of the contact arm portion in the connector width direction may not be regulated.

In view of such circumstances, it is an object of the present invention to provide an electric connector for a flat conductor that can satisfactorily regulate the displacement of the contact arm portion of the terminal while avoiding an increase in size of the electric connector in the connector width direction. ..

In the electric connector for a flat conductor according to the present invention, the flat conductor is connected so that it can be inserted and removed in the front-rear direction, and the width direction of the flat conductor perpendicular to the front-rear direction is the connector width direction, and the front-rear direction and the connector. An electric connector for a flat conductor whose thickness direction is perpendicular to the width direction, and is an electrical insulating material in which a receiving portion is formed as a space open to the rear so that the flat conductor can be inserted. The housing is provided with a plurality of metal terminals arranged and held in the housing within the range of the receiving portion in the width direction of the connector, and a movable member made of an electrically insulating material movable with respect to the housing. The movable member rotates around a rotation axis extending in the connector width direction between a closed position extending in the front-rear direction along the housing when viewed in the connector width direction and an open position standing at an angle with respect to the housing. The plurality of terminals have a contact arm portion extending rearward, and the contact arm portion can be contacted with a flat conductor by a contact portion formed at the rear end portion. There is.

In such an electric connector for a circuit board, in the present invention, the plurality of terminals have a first terminal having a first contact arm portion and a second terminal having a second contact arm portion, and the first contact arm portion. The rear end is located in front of the rear end of the second contact arm portion, and the movable member is in the first contact in the connector width direction and the front-rear direction with the movable member moved to the closed position. A first groove for accommodating the rear end of the first contact arm is formed at a position corresponding to the rear end of the arm, and the second contact is formed at a position corresponding to the rear end of the second contact arm. A second groove portion for accommodating the rear end of the arm portion is formed, and the second groove portion has a groove-shaped portion formed behind the first groove portion in a state where the movable member is in the closed position. It is characterized in that the groove-shaped portion accommodates the rear end of the second contact arm portion.

In the present invention, the groove-shaped portion of the second groove portion accommodating the rear end of the second contact arm portion is formed behind the first groove portion accommodating the rear end of the first contact arm portion. That is, the first groove portion does not exist between the groove-shaped portions of the second groove portions adjacent to each other in the connector width direction. Therefore, the wall thickness dimension (dimension in the connector width direction) of the partition wall is increased, with the portion of the movable member between the groove-shaped portions, in other words, the portion separating the groove-shaped portions (partition wall) as a solid. Even if the distance between the terminals is reduced, sufficient strength of the partition wall is ensured.

In the present invention having such a configuration, the inner wall surface of the first groove portion (the surface perpendicular to the connector width direction) regulates the careless displacement of the first contact arm portion in the connector width direction, and the second The side surface of the partition wall (the surface perpendicular to the connector width direction) between the groove-shaped portions of the groove portion, that is, the inner wall surface of the groove-shaped portion regulates the careless displacement of the second contact arm portion in the connector width direction. Will be done. In particular, the above-mentioned second groove portion that is located behind the rear end of the first contact arm portion, that is, on the opening side of the receiving portion and is capable of contacting the rear end of the second contact arm portion that is susceptible to inadvertent external force. In the partition wall between the groove-shaped portions, sufficient strength of the partition wall is ensured as described above, and the displacement of the rear end of the second contact arm portion and thus the second contact arm portion is more reliably regulated. ..

In the present invention, the movable member has an obtuse angle of rotation from the closed position to the open position, and the first groove portion of the movable member is in the open position when viewed in the connector width direction. Sometimes it extends in the anteroposterior direction, and when the movable member is in the closed position, it may be inclined rearward toward the receiving portion of the housing in the connector thickness direction.

With such a configuration, when the movable member and the housing are molded in the same process to manufacture a connector, if the movable member is molded in the open position, the movable member can be molded. The first groove portion can be easily formed by moving the mold portion straight in the front-rear direction. Further, when the movable member thus formed is moved to the closed position, the first groove portion has a shape that is inclined rearward toward the receiving portion of the housing in the connector thickness direction. Therefore, the inner wall surface of the first groove portion is positioned so as to be separated from the rear end of the first contact arm portion of the first terminal toward the receiving portion of the housing in the connector thickness direction. As a result, interference between the inner wall surface of the first groove portion and the rear end of the first contact arm portion can be more reliably avoided.

In the present invention, the movable member is directed toward the receiving portion side of the housing in the connector thickness direction at a position corresponding to the first terminal in the connector width direction on the rear end side when in the closed position. It has a ridge portion that protrudes and extends in the front-rear direction, and the first groove portion is formed so as to be submerged from the surface of the ridge portion on the receiving portion side when it is in the closed position, and the second groove portion is formed. It may be formed between the ridges adjacent to each other in the connector width direction.

In the present invention, as described above, the groove-shaped portion of the second groove portion accommodating the rear end of the second contact arm portion is formed behind the first groove portion accommodating the rear end of the first contact arm portion. Since the first groove portion does not exist between the groove-shaped portions of the second groove portion adjacent to each other in the connector width direction, the portion between the groove-shaped portions in the movable member, in other words, the groove-shaped portions The wall thickness dimension (dimension in the connector width direction) of the partition wall can be increased by using the portion (partition wall) that separates the partitions as a solid, and even if the distance between the terminals is reduced, the partition wall is sufficiently strong. Can be secured. Therefore, according to the present invention, the inner wall surface between the first groove portions and the inner wall surface of the groove-shaped portion of the second groove portion (the side surface of the partition wall) are used to connect the first contact arm portion and the second contact arm portion, respectively. Inadvertent displacement in the width direction is regulated, and in particular, the rear end of the second contact arm, which is located on the opening side of the receiving portion of the housing and is susceptible to inadvertent external force, and thus the entire second contact arm. Displacement is more reliably regulated by the bulkheads between the second grooves of sufficient strength.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of an electric connector 1 for a flat conductor (hereinafter referred to as “connector 1”) according to the present embodiment. The connector 1 is mounted on a mounting surface of a circuit board (not shown), and a flat conductor F as a mating connector is inserted and removed with the front-back direction (X-axis direction) parallel to the mounting surface as the insertion / removal direction. It is designed to be connected as possible. The connector 1 electrically conducts the circuit board and the flat conductor F by connecting the flat conductor F. In the present embodiment, in the X-axis direction (front-back direction), the X1 direction is the front and the X2 direction is the rear. Further, the Y-axis direction, which is perpendicular to the front-rear direction (X-axis direction) in the plane parallel to the mounting surface of the circuit board (in the XY plane), is the connector width direction, and is perpendicular to the mounting surface of the circuit board. The Z-axis direction (vertical direction) is the connector thickness direction.

The flat conductor F has a strip shape extending in the front-rear direction (X-axis direction) and having the connector width direction (Y-axis direction) as the width direction, and a plurality of circuit portions (not shown) extending in the front-rear direction extend in the connector width direction. It is arranged and formed. The circuit portion is embedded in the insulating layer of the flat conductor F and extends in the front-rear direction, and reaches the front end position of the flat conductor F. Further, the circuit unit has a connection circuit unit F1 whose front end side portion is exposed on the upper surface of the flat conductor F, and can be contacted with the first terminal 20 and the second terminal 30 of the connector 1 described later. It has become. The connection circuit unit F1 has a first connection circuit unit F1A that contacts the first terminal 20 and a second connection circuit unit F1B that contacts the second terminal 30, both of which are displaced in the front-rear direction and in the connector width direction. It is located alternately at.

Further, the flat conductor F has cutouts F2 formed on both side edges of the front end side portion, and the rear end edge of the front ear portion F3 located in front of the cutout portion F2 is a connector 1 described later. It functions as a locked portion F3A that locks with the stop portion 45A (see FIG. 10C). Further, the flat conductor F is formed with a rear ear portion F4 projecting substantially in a triangular shape from both side edges toward the outside in the connector width direction at a position rearward from the notch portion F2. The front end edge of the rear ear portion F4 extends so as to incline rearward as it goes outward in the connector width direction, and the front end edge abuts from the rear with respect to the positioning surface 16C-2 of the housing 10 described later. Therefore, the flat conductor F is positioned at the regular insertion position in the front-rear direction.

The connector 1 includes a housing 10 made of an electrically insulating material, a plurality of metal first terminals 20 and second terminals 30 (see FIG. 2) arranged and held in the housing 10 by integral molding, and a closed position described later. A movable member 40 made of an electric insulating material that can rotate with respect to the housing 10 between the door and the open position, and a metal fitting 50 that is held by the housing 10 by integral molding, and the flat conductor F is rearward. It is designed to be inserted and connected from. Hereinafter, when it is not necessary to distinguish between the first terminal 20 and the second terminal 30, both terminals are collectively referred to as "terminals 20, 30".

Prior to the detailed configuration of the connector 1, first, an outline of the operation of inserting and removing the flat conductor F with respect to the connector 1 will be described. The movable member 40 of the connector 1 rotates between a closed position as a first position for preventing the flat conductor F from being pulled out and an open position as a second position for allowing the flat conductor F to be pulled out. It is possible to move by doing. Before inserting the flat conductor F into the connector 1, as shown in FIG. 1, the movable member 40 of the connector 1 is parallel to the mounting surface (not shown) of the circuit board and the housing 10. The flat conductor F is allowed to be inserted at the closed position as the first position in which the posture is formed. The flat conductor F abuts on the terminals 20 and 30 at its front end edge and elastically displaces the abutting portion of the terminals 20 and 30 so that the flat conductor F can be inserted to a predetermined position (regular insertion position).

Even after the flat conductor F is inserted and connected, the movable member 40 is maintained in the closed position in the used state of the connector 1, and as will be described later, the locking portion 45A of the movable member 40 and the flat conductor F are maintained. By being positioned so that it can be locked with the locked portion F3A, the flat conductor F is prevented from moving backward (in the X2 direction), and the flat conductor F is prevented from being inadvertently pulled out (FIG. 10 (C)). Further, when the flat conductor F is pulled out when the connector 1 is not used, as shown in FIG. 4, the movable member 40 is rotated in the upright direction and is angled with respect to the mounting surface of the circuit board and the housing 10. The locking portion 45A of the movable member 40 is locked to the locked portion F3A of the flat conductor F by being brought to the open position (see FIG. 4C) as the second position forming the standing posture. The state is released, and the movement of the flat conductor F to the rear, that is, the extraction of the flat conductor F is allowed. In the present embodiment, the rotation angle of the movable member 40 from the closed position to the open position is an obtuse angle.

In the present embodiment, the movable member 40 moves between the closed position and the open position only by rotating around the rotation axis extending in the width direction of the connector, but the movable form of the movable member 40 is this. For example, the connector may rotate with a slide movement.

The first terminal 20 has a first contact arm portion 21 that extends in the front-rear direction (X-axis direction) and can be elastically displaced in the vertical direction (Z-axis direction), and is located below the first contact arm portion 21 and moves forward. It has a first connecting portion 22 that extends and a first connecting portion 23 that extends in the vertical direction and connects the front end of the first contact arm portion 21 and the rear end of the first connecting portion 22, and has a substantially crank shape as a whole. (See also FIG. 3 (A)).

The first contact arm portion 21 of the first terminal 20 extends so as to incline slightly downward toward the rear, and is bent so as to project downward at a position near the rear end. It has a part 21A. When the flat conductor F is inserted into the connector 1, the first contact portion 21A is the first connection circuit portion in the front row of the flat conductor F under the elastic displacement of the first contact arm portion 21 facing upward. It can be contacted with F1A (see FIG. 10 (A)).

The rear end side portion and the first connecting portion 23 of the first connecting portion 22 of the first terminal 20 are integrally molded and held by the front frame portion 10A of the housing 10 (see also FIG. 3A). The front end side portion of the first connection portion 22 of the first terminal 20 extends forward from the front frame portion 10A of the housing 10, and is solder-connected to the circuit portion of the circuit board (not shown) on the lower surface thereof. It has become like.

As seen in FIG. 2, the second terminal 30 is made by bending a strip-shaped rolled metal plate whose dimension in the connector width direction is the terminal width direction and bent in the plate thickness direction, similarly to the first terminal 20. A second contact arm portion 31 that extends in the front-rear direction and can be elastically displaced in the up-down direction, and extends in the front-rear direction at a position below the second contact arm portion 31 and is held by the housing 10 at the front end portion and the rear end portion. The held arm portion 32, the curved second connecting portion 33 extending in the vertical direction and connecting the front ends of the second contact arm portion 31 and the held arm portion 32 to each other, and the held arm portion 32 extending rearwardly. A second connecting portion 34 is formed.

The second terminal 30 has the second contact arm portion 31 as one arm portion, the held arm portion 32 as the other arm portion, and the second connecting portion 33 as described above, so that the second terminal 30 is rearward (X2 direction). A horizontal U-shaped portion that opens toward the surface is formed (see also FIG. 3B), and as will be described later, the horizontal U-shaped portion enables the acceptance of the flat conductor F from the rear. At the same time, the second contact arm portion 31 is elastically displaced when the flat conductor F is received, so that the flat conductor F can be pinched between the second contact arm portion 31 and the held arm portion 32.

As seen in FIG. 3B, the second contact arm portion 31 of the second terminal 30 extends so as to incline slightly downward from the upper end of the second connecting portion 33 toward the rear end, and is closer to the rear end. It has a second contact portion 31A that is bent and formed so as to project downward at the position of. The second contact portion 31A is located behind the first contact portion 21A of the first terminal 20 (see also FIG. 3B), and is connected to the second connection circuit portion F1B in the rear row of the flat conductor F. It is designed to be connected. Further, the rear end 31B of the second contact arm 31 is located rearward of the rear end 21B of the first contact arm 21 of the first terminal 20 (see also FIG. 3B).

The held arm portion 32 of the second terminal 30 extends rearward from the lower end of the second connecting portion 33 in parallel with the second contact arm portion 31 and reaches the position of the rear frame portion 10B of the housing 10. The portion near the rear end of the held arm portion 32 is integrally molded by the rear frame portion 10B of the housing 10. Further, the portion of the held arm portion 32 near the front end and the second connecting portion 33 are integrally molded by the front frame portion 10A (see also FIG. 3B). That is, as seen in FIG. 3B, the held arm portion 32 is held in the shape of a double-sided beam by the housing 10.

As seen in FIG. 3B, the held arm portion 32 has a front end side portion 32A connected to the second connecting portion 33, a rear end side portion 32B connected to the second connecting portion 34, and front and rear. It is located in a range including the second contact portion 31A of the second contact arm portion 31 in the direction, and has a support portion 32C that connects the front end side portion 32A and the rear end side portion 32B.

5A is a plan view of the connector 1 when the movable member 40 is in the open position, and FIG. 5B is a bottom view of the connector 1 of FIG. 5A. As can be seen in FIG. 5 (B), the front end side portion 32A has a larger terminal width dimension (dimension in the Y-axis direction) than the second contact arm portion 31 (see also FIG. 5 (A)), and is front and rear. It is formed to have the same width over the entire direction. The rear end side portion 32B is formed with a terminal width dimension smaller than that of the front end side portion 32A.

As seen in FIG. 5B, the support portion 32C is located within the range of the bottom hole portion 17C of the housing 10 in the front-rear direction and the connector width direction. As described above, the support portion 32C is located in the range including the second contact portion 31A of the second contact arm portion 31 in the front-rear direction, and the second contact is made with the flat conductor F connected to the connector 1. The flat conductor F in contact with the second contact portion 31A of the arm portion 31 is supported from below by the rolled surface (support surface) forming the upper surface of the support portion 32C (see FIG. 10B).

As seen in FIG. 5B, the support portion 32C is located so that the side edge on the Y1 side in the connector width direction is further shifted to the Y1 side from the front end side portion 32A, and the opposite is true in the connector width direction. A notch 32C-1 is formed at a position overlapping the second contact portion 31A in the front-rear direction on the side edge portion on the Y2 side located on the side. The terminal width dimension of the support portion 32C is smaller than the terminal width dimension of the front end side portion 32A in the range of the notch portion 32C-1 in the front-rear direction, and is substantially the same as the terminal width dimension of the rear end side portion 32B. Are equal. Further, the terminal width dimension of the support portion 32C is larger than the terminal width dimension of the front end side portion 32A and the rear end side portion 32B in the range other than the notch portion 32C-1 in the front-rear direction. In other words, the maximum terminal width dimension of the support portion 32C is larger than the maximum terminal width dimension of the front end side portion 32A and the rear end side portion 32B.

In the present embodiment, the cutout portion 32C-1 of the support portion 32C is a part of the second contact portion 31A when viewed in the opposite direction (vertical direction) between the second contact arm portion 31 and the held arm portion 32. It is formed at a position that overlaps with. In other words, the support portion 32C is formed in the range of the notch portion 32C-1 so as not to overlap with a part of the second contact portion 31A. That is, as seen in FIG. 5B, when the second terminal 30 is viewed from below, a part of the second contact portion 31A is exposed within the range of the notch portion 32C-1, and the notch is used. It can be visually recognized through the portion 32C-1.

Therefore, a plating material (for example, gold or the like) may be sprayed from below the held arm portion 32 through the notch portion 32C-1 toward the contact surface (lower surface) of the second contact portion 31A of the second contact arm portion 31. By doing so, the plating material can be applied to the contact surface. By applying the plating material through the notch 32C-1 in this way, the range to which the plating material is applied can be limited to the contact surface of the second contact portion 31A and its vicinity, so that the amount of the plating material used Can be kept to the minimum necessary to reduce the manufacturing cost of the second terminal 30. The plating material can be applied through the notch 32C-1 at any time before and after the integral molding of the second terminal 30 and the housing 10.

Further, in the present embodiment, the support portion 32C is formed so that the maximum terminal width is larger and wider than the other portions of the held arm portion 32, that is, the front end side portion 32A and the rear end side portion 32B, and the support portion 32C is formed. The strength of itself is increasing. Therefore, in the support portion 32C, even if the notch portion 32C-1 is formed, the flat conductor F is the second contact portion 31A of the second contact arm portion 31 in a state where the flat conductor F is connected to the connector 1. The flat conductor F can be supported by sufficiently countering the force received from the support portion 32C, that is, the downward force. Further, by providing a circuit portion on the lower surface of the flat conductor F and contacting the support portion 32C to electrically conduct the circuit portion and the support portion 32C, the support portion 32C can be used as a contact portion. It may have a function.

As seen in FIG. 3B, the second connection portion 34 extends rearward from the rear frame portion 10B (see also FIG. 5B), and the circuit board (shown) is the lower surface thereof. It is designed to be solder-connected to the circuit section.

The movable member 40 has a substantially plate-like main body 41 that extends in the front-rear direction (X-axis direction) and the connector width direction (Y-axis direction), as seen in FIG. 1 showing the movable member 40 in a closed position. It has a ridge portion 46 and a rotating shaft portion 47 formed on the rear end side (X2 side) of the main body portion 41 when the movable member 40 is in the closed position.

As seen in FIG. 1, the main body 41 extends over the terminal arrangement range in the connector width direction and covers the terminals 20 and 30 from above at the closed position 42 (FIGS. 3A and 3B). Also referred to), the end arm portion 43 extending rearward at both outer positions of the cover plate portion 42, the connecting portion 44 connecting the front ends of the covering plate portion 42 and the end arm portion 43, and the connecting portion 44. It has a locking arm 45 extending in a cantilever shape from the rear to the rear (see also FIG. 2).

As can be seen in FIG. 1, the cover plate portion 42 has a hole portion 42A that communicates with the first groove portion 46A of the ridge portion 46, which will be described later, in the front-rear direction and the connector width direction at the closed position. It is formed so as to penetrate the cover plate portion 42 in the thickness direction of the portion 42 (see also FIG. 3A).

As seen in FIG. 2, the end arm portion 43 has a lower end portion (rear end portion when the movable member 40 is in the open position) when the movable member 40 is in the open position, which will be described later in the rotation shaft portion 47 in the connector width direction. A fourth shaft portion 47A is located between the first shaft portion 47A and the second shaft portion 47B and forms a part of the rotating shaft portion 47, and connects the first shaft portion 47A and the second shaft portion 47B. It is formed as a shaft portion 47D.

The locking arm 45 is forward (FIG. 2) at the lower end (rear end in FIG. 3C when the movable member 40 is in the closed position), as seen in FIG. 2 where the movable member 40 is in the open position. A locking portion 45A is formed that projects downward in 3 (C). As shown in FIG. 3C, the locking portion 45A rushes into the receiving portion 17A of the housing 10 from above when the movable member 40 is in the closed position. Further, as shown in FIG. 3C, the locking portion 45A moves the flat conductor F forward in the process of inserting the flat conductor F in a state where the movable member 40 is in the closed position. A guide surface 45A-1 for guiding is provided at the rear portion, and after the flat conductor F is inserted, the locked portion F3A formed on the flat conductor F can be locked from the rear. It has a retaining surface 45A-2 at the front (see also FIG. 10C).

As seen in FIG. 3C, the guide surface 45A-1 has an inclined surface that inclines downward as the movable member 40 is in the closed position toward the front. When the front end portion of the front ear portion F3 of the flat conductor F in the process of inserting the flat conductor F abuts on the guide surface 45A-1, the locking arm portion 45 receives the contact force and the locking arm portion 45. The 45 forms an elastic arm portion that is easily elastically displaced upward.

Further, when the movable member 40 is in the open position, the guide surface 45A-1 extends in the vertical direction without being inclined when viewed in the connector width direction, as shown in FIG. 4C. In other words, the guide surface 45A-1 forms a surface perpendicular to the front-rear direction at the open position. Since the guide surface 45A-1 extends in the vertical direction at the open position in this way, as will be described later, the upper mold can be pulled out straight upward after the movable member 40 is formed.

Further, as seen in FIGS. 3C and 10C, the locking surface 45A-2 is seen in the connector width direction when the movable member 40 is in the closed position, and is not tilted in the vertical direction. Extends to. In other words, the locking surface 45A-2 forms a surface perpendicular to the front-rear direction at the closed position. Therefore, in the closed position, the locking surface 45A-2 is located behind the locked portion F3A of the flat conductor F, and is securely locked to the locked portion F3A from the rear, so that the flat conductor It is possible to prevent inadvertent omission of F.

Further, as seen in FIG. 2, the locking arm portion 45 is formed so as to project outward from the locking portion 45A in the connector width direction at a position near the lower end when the movable member 40 is in the open position. It has a regulated protrusion 45B. When the movable member 40 is brought to the closed position, the regulated protrusion 45B enters the space between the front regulation protrusion 16A and the rear regulation protrusion 16B of the housing 10, and the front regulation protrusion 45B enters the space between the front regulation protrusion 16A and the rear regulation protrusion 16B. It is located so that it can abut from the rear with respect to 16A and from the front with respect to the rear regulation protrusion 16B, and is restricted from moving in the front-rear direction (see FIG. 1). Further, the regulated protrusion 45B is formed in a range including a part of the locking portion 45A when viewed in the connector width direction, and also plays a role of reinforcing the strength of the locking portion 45A.

A plurality of ridges 46 are formed at positions corresponding to the first terminal 20 in the connector width direction at intervals, and as seen in FIG. 3A, the movable member 40 covers the movable member 40 when it is in the closed position. It protrudes from the lower surface of the rear end portion of the plate portion 42 and extends rearward (see also FIGS. 1 and 2). Each ridge portion 46 is formed with a first groove portion 46A that is recessed from the lower surface (the surface on the receiving portion 17A side) of the substantially front half portion of the ridge portion 46 when it is in the closed position. The first groove portion 46A is formed at a position corresponding to the rear end 21B of the first contact arm portion 21 of the first terminal 20 in the connector width direction and the front-rear direction in a state where the movable member 40 is in the closed position. As seen in 3 (A), the rear end 21B of the first contact arm 21 is accommodated in the closed position (see also FIG. 9 (B)). As seen in FIGS. 3 (A) and 4 (A), the first groove portion 46A is located corresponding to the hole portion 42A of the cover plate portion 42 and communicates with the hole portion 42A. .. Further, as seen in FIG. 2, it is located substantially below the ridge portion 46 in the open position (approximately the latter half portion in the closed position), that is, below the first groove portion 46A (rear in the closed position). The portion (partition wall 46C described later) is solid over the entire ridge portion 46 in the connector width direction (Y-axis direction) (see also FIGS. 9A and 9B).

Between the ridges 46 adjacent to each other, in other words, at the position corresponding to the rear end 31B of the second contact arm 31 of the second terminal 30 in the connector width direction, as seen in FIG. At the position, a second groove portion 46B extending in the vertical direction (front-back direction in the closed position) over the entire area of the ridge portion 46 is formed (see also FIGS. 3 (B) and 4 (B)). As can be seen in FIG. 3B, the second groove portion 46B is substantially below the lower half portion in the open position (substantially the latter half portion in the closed position), that is, below the first groove portion 46A (rear in the open position). ), The rear end 31B of the second contact arm portion 31 is accommodated when the movable member 40 is brought to the closed position (also in FIG. 9B). reference).

As described above, in the present embodiment, the rear end 21B of the first contact arm portion 21 is accommodated in the first groove portion 46A and the second contact arm portion 31 is accommodated in the second groove portion 46B in the state where the movable member 40 is in the closed position. By accommodating the rear end 31B, the inner wall surface of the first groove portion 46A and the inner wall surface of the second groove portion 46B forming a right angle with respect to the connector width direction of the first contact arm portion 21 and the second contact arm portion 31. Inadvertent displacement of each connector in the width direction is regulated. Further, in the process of inserting the flat conductor F into the connector 1, the flat conductor F does not come into contact with the rear end 21B of the first contact arm portion 21 and the rear end 31B of the second contact arm portion 31. Damage to the terminals 20 and 30 due to buckling or the like can be prevented.

Further, in the present embodiment, a portion of the ridge portion 46 located behind the first groove portion 46A (lower in the open position) in the closed position, in other words, the groove shape of the adjacent second groove portion 46B. A portion that separates the portions forms a partition wall 46C, and the partition wall 46C is solid over the entire ridge portion 46 in the connector width direction (Y-axis direction).

In the present embodiment, the rear end of the second contact arm is located closer to the rear end of the housing 10 than the rear end of the first contact arm, in other words, to the opening side of the receiving portion 17A. The position and orientation of the flat conductor F in the connector width direction are still unstable at the start of insertion of the flat conductor F, that is, immediately after the insertion of the flat conductor F into the rear end opening of the receiving portion 17A is started. Therefore, the rear end of the second contact arm portion is more likely to receive an inadvertent external force from the flat conductor F in the connector width direction than the rear end of the first contact arm portion.

However, in the present embodiment, as described above, the strength of the partition wall 46C itself can be increased by making the partition wall 46C solid and increasing the wall thickness dimension (dimension in the connector width direction) of the partition wall 46C as much as possible. Therefore, even if a large number of terminals 20 and 30 are provided and the distance between the second terminals 30 must be reduced, sufficient strength of the partition wall 46C is ensured. Therefore, the side surface of the partition wall 46C (the surface perpendicular to the connector width direction), in other words, the inner wall surface of the groove-shaped portion of the second groove portion 46B causes the second contact arm portion 31 to be inadvertently displaced in the connector width direction. Can be regulated more reliably.

As can be seen in FIG. 2, at the lower portion of the partition wall 46C of each ridge portion 46 (the rear portion when the movable member 40 is in the closed position), both side surfaces in the connector width direction are forward (the movable member 40 is closed). A slope 46C-1 is formed inward in the connector width direction toward the lower side when in the position. As described above, in the present embodiment, since the slope 46C-1 is formed on the partition wall 46C, temporarily, with the movable member 40 in the open position, the rear end 31B of the second contact arm portion 31 of the second terminal 30 Is slightly deviated from the normal position in the connector width direction, but in the rotation process from the open position to the closed position of the movable member 40, the rear end 31B abuts on the slope 46C-1 and slides into contact with the slope 46C-1. , The movable member 40 is surely guided into the second groove portion 46B. Therefore, in the rotation process, it is possible to prevent the rear end 31B from coming into contact with the partition wall 46C and the second contact arm portion 31 from being inadvertently deformed. Further, as described above, since the partition wall 46C is formed with a large wall thickness dimension, sufficient strength of the partition wall 46C is ensured even if the slope 46C-1 is formed on the partition wall 46C.

As described above, the first groove portion 46A communicates with the hole portion 42A of the cover plate portion 42, and as seen in FIGS. 3 (A) and 4 (A), the inner wall surface and the hole of the first groove portion 46A. A flat surface is formed continuously with the inner wall surface of the portion 42A. The continuous inner wall surface of the first groove portion 46A and the hole portion 42A and the inner wall surface of the second groove portion 46B extend straight without being inclined in the front-rear direction when the movable member 40 is in the open position when viewed in the connector width direction. (See FIGS. 4A and 4B), when the movable member 40 is in the closed position, it is inclined rearward as it goes downward (see FIGS. 3A and 3B).

Therefore, when the movable member 40 and the housing 10 are molded in the same process to manufacture the connector 1, if the movable member 40 is molded in the open position, the movable member 40 can be molded. By moving the mold portion straight in the front-rear direction, the first groove portion 46A and the second groove portion 46B can be easily formed.

Further, as described above, when the movable member 40 is brought to the closed position, the inner wall surface formed by the first groove portion 46A is inclined rearward as it goes downward when viewed in the connector width direction (FIG. 3 (FIG. 3). See A)). Therefore, in the closed position, the inner wall surface located on the rear side (X2 side) of the inner wall surface of the first groove portion 46A is the first contact arm portion 21 of the first terminal 20 housed in the first groove portion 46A. It will be located away from the rear end 21B. As a result, the interference between the movable member 40 brought from the open position to the closed position and the rear end 21B of the first contact arm portion 21 can be more reliably avoided, and damage to the first contact arm portion 21 can be prevented.

As seen in FIGS. 4A and 4B, when the movable member 40 is in the open position, the first groove portion 46A and the second groove portion 46B of the movable member 40 are the rear ends of the first contact arm portion 21. It is located posterior to the rear end 31B of the 21B and the second contact arm 31 (see also FIG. 9A). That is, the rear end 21B and the rear end 31B are not located in the first groove portion 46A and the second groove portion 46B, respectively. Therefore, when the movable member 40 and the housing 10 are molded in the same process to manufacture the connector 1, if the movable member 40 is molded in the open position, the first groove portion 46A and the first groove portion 46A and the first groove portion 46A in the mold are formed. The mold portion corresponding to the two-groove portion 46B does not need to have a complicated shape in order to avoid interference with the rear end 21B of the first contact arm portion 21 and the rear end 31B of the second contact arm portion 31, and the first It can have a simple shape corresponding to the groove portion 46A and the second groove portion 46B. As a result, it is possible to secure sufficient strength in the mold portion and avoid damage.

The rotation shaft portion 47 of the movable member 40 has a non-cylindrical surface on the outer peripheral surface around the rotation axis, and extends in the connector width direction at a position including the rotation axis of the movable member 40. It has a shaft portion 47A, a second shaft portion 47B, a third shaft portion 47C, and a fourth shaft portion 47D. As can be seen in FIG. 2, in the state where the movable member 40 is in the open position, the first shaft portion 47A protrudes outward in the connector width direction from the fourth shaft portion 47D forming the lower end portion of the end arm portion 43. .. The second shaft portion 47B is located below the locking arm portion 45, and is the lower end portion of the ridge portion 46 and the fourth shaft portion 47D (the lower end portion of the end arm portion 43) located at the end position in the connector width direction. ) Is connected. The third shaft portion 47C projects outward from the first shaft portion 47A in the connector width direction. The fourth shaft portion 47D forms the lower end portion of the end arm portion 43, is located between the first shaft portion 47A and the second shaft portion 47B in the connector width direction, and is located between the first shaft portion 47A and the second shaft portion 47A. It is connected to the biaxial portion 47B. The rotating shaft portion 47 is housed in the housing portion 18 of the housing 10.

FIG. 6A in FIGS. 6 and 7 is a connector. The cross section at the position of the first shaft portion 47A in the width direction, (B) is the cross section at the position of the second shaft portion 47B in the connector width direction, and (C) is the cross section of the third shaft portion 47C in the connector width direction. The cross section at the position is shown.

When the movable member 40 is in the open position, the first shaft portion 47A has a substantially rectangular shape having a cross-sectional shape perpendicular to the connector width direction and a vertical direction as a longitudinal direction, as shown in FIG. 7 (A). The cross-sectional area thereof is larger than the cross-sectional area of each of the second shaft portion 47B and the third shaft portion 47C. As can be seen in FIG. 7A, in the cross-sectional shape of the first shaft portion 47A, the front surface and the rear surface form a flat surface extending straight without being inclined in the vertical direction, and the upper surface is convexly curved upward. It has a curved surface, and the lower surface is curved downward. Here, the front surface of the first shaft portion 47A at the open position as seen in FIG. 7A is the "flat surface 47A-1", the rear surface is the "flat surface 47A-2", and the upper surface is the "curved surface 47A-3". , The lower surface is "curved surface 47A-4".

In the state where the movable member 40 is rotated to the closed position, as seen in FIG. 6A, the flat surface 47A-1 (front surface in the open position) and the flat surface 47A-2 (front surface in the open position) of the first shaft portion 47A ( The rear surface in the open position) is positioned so as to incline rearward as it goes upward, and forms the lower surface and the upper surface of the first shaft portion 47A in the closed position, respectively. Further, the curved surface 47A-3 (upper surface in the open position) and the curved surface 47A-4 (lower surface in the open position) of the first shaft portion 47A form the front surface and the rear surface of the first shaft portion 47A in the closed position, respectively. Eggplant.

As seen in FIG. 7B, the second shaft portion 47B has a substantially pentagonal cross-sectional shape perpendicular to the connector width direction when the movable member 40 is in the open position, and the outer circumference thereof. Of the surfaces, the lower surface forms a flat surface that extends straight without being inclined in the front-rear direction, and the front surface of the upper portion of the second shaft portion 47B forms a flat surface that inclines backward as it goes upward. Here, the lower surface of the second shaft portion 47B at the open position as seen in FIG. 7B is referred to as a “flat surface 47B-1”, and the front surface of the upper portion is referred to as a “flat surface 47B-2”.

In the state where the movable member 40 is rotated to the closed position, as seen in FIG. 6B, the flat surface 47B-1 (lower front surface in the open position) of the second shaft portion 47B faces upward. As it is positioned so as to incline forward, it becomes the rear surface of the second shaft portion 47B. Further, the flat surface 47B-1 (the front surface of the upper portion in the open position) is positioned so as to extend straight without being inclined with respect to the front-rear direction, and becomes the lower surface of the second shaft portion 47B.

As seen in FIGS. 6 (C) and 7 (C), the third shaft portion 47C is located below the movement restricting portion 51 described later of the metal fitting 50, and moves upward by a predetermined amount or more. It has a function as a movement control unit that receives the regulation of the above from the movement regulation unit 51.

As seen in FIG. 7C, the third shaft portion 47C has a cross-sectional shape perpendicular to the connector width direction when the movable member 40 is in the open position, and has a substantially pentagon with the vertical direction as the longitudinal direction. It has a shape, and among its outer peripheral surfaces, the upper surface forms a flat surface that extends straight without inclining in the front-rear direction, and the lower rear surface is formed as a flat surface that inclines backward as it goes upward. .. Here, the upper surface of the second shaft portion 47B at the open position as seen in FIG. 7C is referred to as a “flat surface 47C-1”, and the rear surface of the lower portion is referred to as a “flat surface 47C-2”. In this open position, as seen in FIG. 7C, the flat surface 47C-1 of the third shaft portion 47C is in contact with the lower surface of the movement restricting portion 51 of the metal fitting 50, whereby the movable member 40 Is maintained in the open position.

In the state where the movable member 40 is rotated to the closed position, as seen in FIG. 6C, the flat surface 47C-1 (upper surface in the open position) is positioned so as to be inclined forward as it goes upward. It is the front surface of the third shaft portion 47C. Further, the flat surface 47C-2 (the rear surface of the lower portion in the open position) is positioned so as to extend straight without being inclined with respect to the front-rear direction, and becomes the upper surface of the third shaft portion 47C. In this closed position, as seen in FIG. 6C, the flat surface 47C-2 of the third shaft portion 47C is in contact with the lower surface of the movement restricting portion 51 of the metal fitting 50, whereby the movable member 40 Is kept in the closed position.

In the present embodiment, in the process of rotating the movable member 40 between the closed position and the open position, the third shaft portion 47C is placed on the lower surface while receiving the contact force from the lower surface of the movement restricting portion 51 of the metal fitting 50. It slides and rotates. As described above, the third shaft portion 47C has a non-cylindrical outer peripheral surface, and is the third shaft from the position of the rotation axis (position of the rotation center) of the movable member 40 when viewed in the connector width direction. The linear distance between the portion 47C and the movement restricting portion 51 to the contact position is not constant in the rotation process of the movable member 40. Therefore, in the rotation process, the position of the third shaft portion 47C in the vertical direction is such that the third shaft portion 47C moves up and down by receiving the contact force from the movement restricting portion 51. That is, the third shaft portion 47C has a function as a so-called cam portion.

In the present embodiment, as seen in FIGS. 6 (A) and 7 (A), the first shaft portion 47A is formed with the front inner wall surface 18A-1 and the rear inner wall surface 18A-2 of the outer accommodating portion 18A, respectively. In a state where a gap in the front-rear direction (hereinafter, referred to as "front-back direction gap") is formed between the two, the outer housing portion 18A is accommodated. In the present embodiment, the front-rear direction gap between the movable member 40 and the front inner wall surface 18A-1 is "C1", and the front-rear direction gap between the movable member 40 and the rear inner wall surface 18A-2 is "C2". (See FIGS. 6 (A) and 7 (A)). As can be seen by comparing FIGS. 6A and 7A, the dimensions of the front-rear gaps C1 and C2 at the closed position are smaller than those of the front-rear gaps C1 and C2 at the open position. As described above, the first shaft portion 47A has a shape in which the front-rear direction gaps C1 and C2 in the closed position are smaller than the front-rear direction gaps C1 and C2 in the open position.

Further, as seen in FIGS. 6B and 7B, the second shaft portion 47B has a vertical gap between it and the shaft regulation surface 16C-1 which is the upper surface of the shaft regulation protrusion 16C. It is housed in the inner accommodating portion 18B in a state where (hereinafter, referred to as "vertical gap") is formed. In the present embodiment, the vertical gap between the movable member 40 and the shaft regulating surface 16C-1 when the movable member 40 is in the closed position is defined as "C3" (see FIGS. 6 (B) and 7 (B)). As can be seen by comparing FIG. 6 (B) and FIG. 7 (B), the dimension of the vertical gap C3 at the closed position is smaller than that of the vertical gap C3 at the open position. As described above, the second shaft portion 47B has a shape in which the vertical gap C3 in the closed position is smaller than the vertical gap C3 in the open position.

The housing 10 and the movable member 40 are so-called simultaneous molded products, and as will be described later, they are molded in the same process when the connector 1 is manufactured. In the present embodiment, the movable member 40 is molded in an open position, and when the housing 10 and the movable member 40 are molded, a part of the mold is vertically formed in the front-rear gaps C1 and C2. (See FIG. 8A), a part of the mold is inserted into the vertical gap C3 in the front-rear direction. As described above, since the dimensions of the front-rear gaps C1 and C2 and the vertical gaps C3 are larger than the dimensions at the closed position, the mold portions inserted into the front-rear gaps C1 and C2. The vertical dimension and the vertical dimension of the mold portion inserted into the vertical gap C3 can be increased, and sufficient strength is ensured for these mold portions.

In the present embodiment, the front-rear direction gaps C1 and C2 at the position of the first shaft portion 47A when the movable member 40 is in the open position form slits extending vertically in the vertical direction with equal gap dimensions. Further, the vertical gap at the position of the second shaft portion 47B when the movable member 40 is in the open position forms a slit extending linearly in the front-rear direction with equal gap dimensions. Therefore, the shape of the mold portion inserted into each of the front-rear gaps C1 and C2 and the vertical gap C3 at the time of molding the movable member 40 can be simplified as a straight shape.

Further, when the connector is used, the movable member 40 is brought from the open position to the closed position, and the front-rear direction gaps C1 and C2 and the vertical direction gap C3 are smaller than when the movable member 40 is in the open position. Therefore, the front-rear direction gaps C1 and C2 and the vertical-direction gap C3 are equal to or less than the allowable gap amount, and even if the flat conductor F receives external force in the front-rear direction (insertion / extraction direction) and the vertical direction when using the connector, the first shaft portion 47A The backlash in the front-rear direction is suppressed at the position of, and the backlash in the vertical direction is suppressed at the position of the second shaft portion 47B. As a result, the contact state between the flat conductor F and the terminals 20 and 30 is less likely to be adversely affected.

As seen in FIG. 2, the metal fitting 50 is integrally molded by the side wall 15 of the housing 10 at a position corresponding to the outer accommodating portion 18A of the housing 10 and the third shaft portion 47C of the movable member 40 in the connector width direction. It is held. The metal fitting 50 is formed by bending a strip piece made of a rolled metal plate in the plate thickness direction, and the rolled surface (plate surface) is formed on the side wall 15 in a posture parallel to the connector width direction. It is held.

As seen in FIGS. 2, 6 (C) and 7 (C), the metal fitting 50 has a movement restricting portion 51 extending in the front-rear direction and a housing 10 bent at the front end of the movement restricting portion 51 and extending downward. The front held portion 52 held by the housing 10, the rear held portion 53 extending from the rear end of the movement restricting portion 51 in a crank shape and held by the housing 10, and the housing 10 rearward from the rear held portion 53. It has a fixing portion 54 extending to the outside.

As seen in FIGS. 6C and 7C, the movement restricting portion 51 is located in the outer accommodating portion 18A of the housing 10, and is located in the front-rear direction, that is, the front inner wall surface 18A- of the outer accommodating portion 18A. It extends forward and backward from the third shaft portion 47C of the movable member 40 in the opposite direction between 1 and the rear inner wall surface 18A-2, and is exposed from the housing 10.

In the present embodiment, the rolling surface (plate surface) of the movement restricting unit 51 is perpendicular to the vertical direction (connector thickness direction), in other words, the vertical direction is the plate thickness direction. Therefore, according to the present embodiment, the movement restricting portion 51 is moved up and down as compared with the case where the rolling surface (plate surface) of the plate-shaped movement restricting portion is provided at a right angle to the connector width direction. The directional dimension becomes smaller. Therefore, the vertical dimension of the housing 10 that holds the metal fittings and thus the connector 1 can be reduced.

In the present embodiment, the lower surface of the movement restricting portion 51 is located in contact with the upper surface of the third shaft portion 47C (flat surface 47C-1 in the closed position, flat surface 47C-1 in the open position). Alternatively, the lower surface of the movement restricting portion 51 may be formed with a slight gap from the upper surface of the third shaft portion 47C. In this case, the movement restricting unit 51 restricts the upward movement of the third shaft portion 47C by a predetermined amount or more corresponding to the size of the gap.

Further, as seen in FIG. 2, the movement restricting portion 51 is provided at an intermediate position in the outer accommodating portion 18A in the connector width direction. The spaces forming a part of the outer accommodating portion 18A on both sides of the movement restricting portion 51 in the connector width direction are formed so as to have the same width over the entire vertical direction when viewed in the front-rear direction. That is, the space is not shaped so as to become narrower as it goes upward. Therefore, at the time of manufacturing the connector 1, a part of the mold (upper mold M1 described later) can be arranged from above at a position corresponding to the space, and the part of the mold and the movement restricting portion 51 can be arranged. By cooperating, the metal fitting 50 and the housing 10 can be integrally molded.

As seen in FIGS. 6 (C) and 7 (C), the front held portion 52 extends through the front bent portion 52A which is bent downward at the front end of the movement restricting portion 51. The entire front held portion 52 is embedded and held by the housing 10 by integral molding.

As seen in FIGS. 6 (C) and 7 (C), the rear held portion 53 extends through the rear upper bent portion 53A that is bent downward at the rear end of the movement restricting portion 51, and further extends. It extends through the rear lower bending portion 53B that is bent toward the rear, and has a crank shape as a whole. The entire rear held portion 53 is embedded and held by the housing 10 by integral molding.

In this way, the metal fitting 50 is held by the held portions 52 and 53 in the housing 10 by integral molding. Therefore, the contact area between the metal fitting 50 and the housing 10, that is, the area where the metal fitting 50 is held by the housing 10 is larger than that when the metal fitting is press-fitted and held in the housing, and the metal fitting 50 is firmly held by the housing 10. It is held. As a result, even if the movement regulating unit 51 receives a strong contact force from the third shaft portion 47C when restricting the movement of the third shaft portion 47C, it opposes the corresponding contact force with sufficient strength, and the third shaft The movement of the part 47C can be regulated more reliably.

In the present embodiment, the bent portion (front bent portion) bent in the plate thickness direction by the front held portion 52 and the rear held portion 53 (hereinafter, collectively referred to as “held portions 52, 53” as needed). Since 52A, the rear upper bending portion 53A, and the rear lower bending portion 53B) are formed, the strength of the held portions 52, 53 itself can be improved. Further, by forming the bent portion in this way, the held portions 52 and 53 held by the housing are lengthened, and the contact area with the housing 10 when integrally molded with the housing 10 is increased. It is possible to improve the holding force of the housing 10.

The fixed portion 54 extends rearward from the rear held portion 53 in a straight shape and extends from the side wall 15. The lower surfaces of the fixing portion 54 (C) and 7 (C) are located at substantially the same height as the lower surface of the housing 10, and are fixed to the corresponding portions on the mounting surface of the circuit board by solder connection. It has become so. By providing the fixing portion 54 on the metal fitting 50 in this way, the metal fitting 50 is fixed to the mounting surface of the circuit board by the fixing portion 54, so that the movement restricting portion 51 can move the third shaft portion 47C of the movable member 40. When regulating, it is possible to counter the contact force received from the third shaft portion 47C with sufficient strength.

Since the movement restricting portion 51 of the metal fitting 50 is held by the housing 10 by the held portions 52 and 53 formed on both sides in the front-rear direction with respect to the movement restricting portion 51, the movement restricting portion 51 is a double-sided beam. It is in shape. Therefore, when the movement restricting portion 51 restricts the movement of the third shaft portion 47C of the movable member 40, it is possible to counter the contact force received from the third shaft portion 47C with sufficient strength.

The connector 1 having the above configuration is manufactured as follows.

First, the terminals 20, 30 and the metal fittings 50 are molded so that the rolled surfaces of these members are parallel to the connector width direction (upper mold M1, lower mold M2 and rear mold M3 described later). ), And held by the mold. Specifically, the upper mold M1 arranged from above, the lower mold M2 arranged from below, and the rear mold M3 arranged from the rear (see FIGS. 8A and 8B). The first contact arm portion 21 of the one terminal 20, the held arm portion 32 of the second terminal 30, and the movement restricting portion 51 of the metal fitting 50 are held.

At this time, at the position of the first shaft portion 47A in the connector width direction, as seen in FIG. 8A, the positions corresponding to the front-rear direction gaps C1 and C2 in the front-rear direction (see FIG. 7A). The mold portion M1A of the upper mold M1 is arranged from above, and the mold portion M2A of the lower mold M2 is arranged from below. Further, at the position of the second shaft portion 47B in the connector width direction, the mold portion of the rear mold M3 (not shown) is located at a position corresponding to the vertical gap C3 (see FIG. 7B) in the front-rear direction. Is placed from the back.

In the present embodiment, since the movable member 40 is molded in the open position, the front-rear direction gaps C1 and C2 are largely secured, and the mold portion M1A of the upper mold M1 and the mold of the lower mold M2 are formed. The mold portion M2A is formed with a thickness dimension (front-back direction dimension) corresponding to the front-rear direction gaps C1 and C2. Therefore, it is possible to secure the strength of the mold portions M1A and M2A by the thickness dimension thereof, and it is possible to satisfactorily prevent damage to the mold portions M1A and M2A. Further, since the vertical gap C3 is also largely secured, the mold portion of the rear mold M3 is formed with a thickness dimension (vertical dimension) corresponding to the vertical gap C3. Therefore, the strength of the mold portion can be ensured by the thickness dimension thereof, and damage to the mold portion can be satisfactorily prevented.

At the positions of the metal fitting 50 and the third shaft portion 47C of the movable member 40 in the connector width direction, the upper mold M1 abuts on the upper surface of the entire movement restricting portion 51 of the metal fitting 50, as shown in FIG. 8 (B). , The mold portion M2B of the lower mold M2 comes into contact with the lower surfaces of the front end side portion and the rear end side portion of the movement restricting portion 51. As described above, the upper surface and the lower surface of the flat rolled surface of the movement restricting portion 51 are used as contact surfaces with the molds M1 and M2.

In the present embodiment, the lower mold M2 is outside the terminal arrangement range in the connector width direction and overlaps with the space for molding the housing 10 in the mold, specifically, when viewed from below. , A space for molding the movable member (not shown) for molding the movable member 40 in the range corresponding to the intermediate accommodating portion 18C of the housing 10 (see FIG. 5 (B)) moves the lower mold M2 in the vertical direction. It is formed through the housing. A movable member molding gate block (not shown) for molding the movable member 40 is arranged from below in the movable member molding vacant space. In the movable member molding gate block, the electrically insulating material melted into the space for molding the movable member 40 in the mold is injected from the injection port of the movable member molding gate block.

Further, in any of the molds, a housing molding space (not shown) for molding the housing 10 is formed through the mold at a position different from the movable member molding space. ing. A housing molding gate block (not shown) for molding the housing 10 is arranged in the housing molding void. In the housing molding gate block, the electrically insulating material melted into the space for molding the housing 10 in the mold is injected from the injection port of the housing molding gate block.

Next, the electrically insulating material injected into the mold from each of the movable member molding gate block and the housing molding gate block is cooled and solidified, so that the movable member 40 is in the open position with the housing 10. And are molded at the same time. At this time, the terminals 20, 30 and the metal fitting 50 are held by the housing 10 by integral molding. Further, as seen in FIG. 8B, at the position of the metal fitting 50 in the connector width direction, the movement restricting portion 51 of the metal fitting 50 is formed in the outer accommodating portion 18A of the housing 10, and the movement thereof is performed. The third shaft portion 47C of the movable member 40 is formed in a space surrounded by the lower surface of the restricting portion 51 and the lower mold M2 in a state of being in contact with the lower surface of the movement restricting portion 51.

Next, the gate block for molding the movable member is pulled out from the empty space for molding the movable member, and the gate block for molding the housing is pulled out from the empty space for molding the housing and removed. At this time, the intermediate accommodating portion 18C is formed in the housing 10 by pulling out the movable member molding gate block. Further, the upper mold M1 is moved upward (Z1 direction), the lower mold M2 is moved downward (Z2 direction), and the rear mold M3 is moved straight backward (X2 direction) to remove the mold M1.

Further, in the present embodiment, as described above, the movable member 40 is molded in the open position. Therefore, immediately after molding, the movable member 40 guides the locking portion 45A when viewed in the connector width direction. Surface 45A-1 extends straight in the vertical direction (see FIG. 4C). Therefore, when the upper mold M1 is removed, the upper mold M1 can be removed upward along the guide surface 45A-1, so that the connector 1 is manufactured with the upper mold M1 having a simple shape. be able to.

After removing the molds M1, M2, and M3, the movable member 40 is rotated from the open position to the closed position side, so that the third shaft portion 47C of the movable member 40 is moved to the movement restricting portion 51 of the metal fitting 50. By separating the movable member 40 from the lower surface of the cable and making the movable member 40 movable, the connector 1 is completed in a usable state. The rotation operation of the movable member 40 may be performed at any stage after removing the molds M1, M2, and M3, and may be performed by the manufacturer before shipping the connector 1, for example. After the connector is shipped, it may be performed by the user at the start of using the connector.

As described above, in the connector 1 according to the present embodiment, the terminals 20, 30 and the metal fitting 50 are integrally molded at the same time as the housing 10 and the movable member 40, and then the movable member 40 is simply moved between the open position and the closed position. Can be manufactured at. Therefore, it is not necessary to process any of the connector components after the integral molding, and the connector can be easily manufactured in a small number of steps. In addition, the manufacturing cost of the connector can be suppressed because the number of processes is reduced.

In the present embodiment, the space for molding the movable member of the lower mold M2 is on the lower side in the connector thickness direction (vertical direction) within a range overlapping the space for molding the housing 10 in the mold. That is, it is formed by opening on the side opposite to the side (upper side) where the movable member 40 is provided. Therefore, due to the structure of the mold (shape division position, etc.), a space for molding a movable member cannot be formed on the upper side of the mold, that is, a gate block for molding a movable member cannot be arranged on the upper side of the mold. Even so, the movable member 40 can be molded by forming a movable member molding vacant space on the lower side of the mold and arranging the movable member molding gate block in the movable member molding vacant space. Further, since the housing molding gate block is arranged at a position different from the position of the movable member molding gate block, the housing 10 and the movable member 40 can be molded in the same process.

Further, in the present embodiment, the movable member molding gate block is arranged at the position of the intermediate accommodating portion 18C (see FIG. 5B) of the housing 10, and the injection port of the movable member molding gate block is the movable member 40. It is located in the range of the fourth shaft portion 47D (see FIG. 5B). Therefore, a so-called injection mark is formed on the surface of the fourth shaft portion 47D, which is the portion where the injection port is located, when the gate block for molding the movable member is removed after molding the movable member 40. The injection mark may be formed in a protruding shape protruding from the surface of the fourth shaft portion 47D. In the present embodiment, the injection mark is formed on the fourth shaft portion 47D located outside the range of the receiving portion 17A of the housing 10 in the connector width direction. Therefore, even if the injection mark has a protrusion shape, the injection mark is formed. The mark does not protrude into the receiving portion 17A. As a result, it is possible to prevent the flat conductor F from interfering with the injection mark during and after the flat conductor F is inserted into the receiving portion 17A.

In the present embodiment, when the movable member 40 is molded, the gate block for molding the movable member is arranged at the position of the intermediate accommodating portion 18C outside the terminal arrangement range in the connector width direction. The gate block does not interfere with the terminals 20 and 30. Therefore, the mold has a simple shape in which the space for molding the movable member extends straight toward the space inside the mold (the space for molding the movable member) in the connector thickness direction (vertical direction). It only needs to be formed, and the shape and structure of the mold will not be complicated. Further, the position where the movable member molding gate block is arranged is not limited to the outside of the terminal arrangement range, and may be a position where interference with terminals and metal fittings can be avoided, for example, a position between adjacent terminals. It may be.

Next, the connection operation between the connector 1 and the flat conductor F will be described.

First, the first connection portion 22 of the first terminal 20 of the connector 1 and the second connection portion 34 of the second terminal 30 are solder-connected to the corresponding circuit portion of the circuit board (not shown), and the fixing portion 54 of the metal fitting 50 is connected. Is soldered to the corresponding part of the circuit board. The connector 1 is attached to the circuit board by the solder connection of the first connection portion 22, the second connection portion 34, and the fixing portion 54.

Next, as shown in FIG. 1, a flat conductor F extends in the front-rear direction along a mounting surface of a circuit board (not shown) behind the connector 1 in a state where the movable member 40 is brought to the closed position. Position it like this. Next, the flat conductor F is inserted into the receiving portion 17A of the connector 1 with the flat conductor F facing forward.

In the process of inserting the flat conductor F into the receiving portion 17A, the front end of the flat conductor F first abuts on the second contact portion 31A of the second contact arm portion 31 of the second terminal 30 and is subjected to the contact force. By pushing up the second contact portion 31A with a directional component force, the second contact portion 31A is elastically displaced upward. When the flat conductor F is further inserted, the front end of the flat conductor F abuts on the first contact portion 21A of the first contact arm portion 21 of the first terminal 20 and pushes up the first contact portion 21A. Elastically displaces upwards.

As seen in FIGS. 10A and 10B, even when the flat conductor F has been inserted, the first contact arm portion 21 of the first terminal 20 and the second contact arm portion of the second terminal 30 31 remains elastically displaced. As a result, the first contact portion 21A and the second contact portion 31A are maintained in contact with the first connection circuit portion F1A and the second connection circuit portion F1B (see FIG. 1) of the flat conductor F with contact pressure, respectively. ..

Further, in the process of inserting the flat conductor F into the receiving portion 17A, the front ear portions F3 located near both ends in the width direction of the flat conductor F are locked formed on the locking arm portion 45 of the movable member 40. The flat conductor F is guided to a regular insertion position in the vertical direction by abutting and sliding contact with the guide surface 45A-1 of the portion 45A. Further, the front ear portion F3 elastically displaces the locking arm portion 45 upward by the vertical component of the contact force with the guide surface 45A-1, and brings the locking arm portion 45 to a position where the flat conductor F can be inserted. Further, when the flat conductor F is inserted and the front ear portion F3 passes the position of the locking portion 45A, the locking arm portion 45 is displaced downward so as to reduce the amount of elastic displacement and returns to the free state, and is flat. It rushes into the notch F2 of the mold conductor F. As a result, when the flat conductor F shown in FIG. 10C is completely inserted, the locked portion F3A of the flat conductor F is in front of the locking surface 45A-2 of the locking portion 45A. It is positioned so that it can be locked to 45A-2, and the flat conductor F is prevented from being pulled out to the rear. It is not essential that the locking arm 45 returns to a completely free state. For example, with the locking arm portion 45 leaving a small amount of elastic displacement, the locking portion 45A rushes into the notch F2 of the flat conductor F and is positioned so as to be able to be locked with the locked portion F3A. It is also possible to have a different configuration.

When the flat conductor F in the state shown in FIGS. 10A to 10C, that is, in the state of being connected to the connector 1, is intentionally pulled out from the connector 1, the movable member 40 in the closed position is rotated. Move it to the open position (see FIG. 4C). When the movable member 40 is in the open position, the locking portion 45A of the locking arm portion 45 of the movable member 40 is positioned so as to be offset upward from the cutout portion F2 of the flat conductor F. That is, the locked state of the locked portion 45A with respect to the locked portion F3A of the flat conductor F is released, and the flat conductor F is allowed to be pulled out to the rear. Then, in this state, if the flat conductor F is pulled backward, the flat conductor F can be easily pulled out from the connector 1.
