Description

Connector {Connector}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for electrically connecting a plate-like connection object such as a flexible printed circuit board (FPC) or a flexible flat cable (FFC) to an electrical substrate.

Conventionally, the connector of Japanese Patent Laid-Open No. 2006-114436 includes an insulator (housing) and a plurality of contacts fixed to the insulator, a fully open position (position approximately perpendicular to the insulator away from the surface of the insulator) and a completely closed position (surface of the insulator). It has an actuator (rotational movement material) which rotatably supported between the insulator which covered the space and the position which becomes substantially parallel. In addition, an engaging portion is designed in the connection object FPC that can be inserted into or removed from the connector, and one actuator is provided with an engaging portion that can be fitted with the engaging portion.

Therefore, after inserting the connection object into the housing while the actuator is in the fully open position and making electrical contact with the contact, the actuator is rotated to the fully closed position so that the fitting of the actuator is fitted to the engaging portion of the connection object. As a result, the connection object is prevented from easily falling off the connector (insulator).

The connector of Japanese Patent Laid-Open No. 2006-114436 has the following drawbacks.

That is, when the conventional connector structure of Japanese Patent Laid-Open No. 2006-114436 is applied to a very small connector (for example, a height of 1 mm or less and a long dimension and a short dimension of several mm), the actuator size also becomes small. The operability of the deteriorates. Therefore, in this case, it is intended to maximize the operability of the actuator by making the size of the actuator as large as possible (as close as possible to the size of the insulator).

However, when the actuator is enlarged in size in plan view, most of the surface of the insulator is covered by the actuator when the actuator is in the fully closed position. Therefore, the flat surface (so-called adsorption surface) adsorbed by the adsorption means when transferred to the electric board mounting the connector is formed on the surface of the actuator and not the insulator.

However, in the case where the flat surface is formed on the actuator, if the actuator is positioned at a position other than the fully closed position, the flat surface is inclined with respect to the electric substrate. Therefore, the connector (actuator) is not provided when the actuator is in the fully closed position. It cannot be transferred to the electrical substrate by the adsorption means. Therefore, in order to connect an FPC or the like to a connector mounted on an electric board, it is necessary to move the actuator to the fully open position once after mounting and then to return to the fully closed position, which is laborious.

Therefore, the large actuator in the small connector becomes an advantage from the viewpoint of operability, and becomes a defect rate betrayer from the viewpoint of the adsorption surface to be transferred.

An object of the present invention is to provide a connector with excellent productivity, which can improve the operability of the actuator even when the connector is made small, and furthermore, it is possible to stably move by the suction means regardless of the position of the actuator.

The connector of the present invention is an insulator capable of inserting and removing a flat plate connection object having a engagement portion, which is a cutout groove formed in an engagement hole or a periphery, and a connector electrically connected to the connection object fixed to the insulator and inserted into the insulator. And rotatable in the fully closed position with respect to the insulator about the surface of the insulator and in an open position facing away from the surface relative to the fully closed position while being in the fully closed position. And an actuator having an engaging structure that can be engaged with the engaged portion, and a lock-holding means for holding the actuator located in the fully closed position in its fully closed position, forming a flat surface for dissimilarity on the surface of the insulator, and On that When a chooser radiator positioned in the fully closed position and the open position is characterized by forming a window hole for exposing the flat surface.

When the actuator is in the open position, the engagement structure may not be fitted with the engagement portion.

At least one of the actuator and the insulator is fitted to the other when the actuator is in the open position, restricting rotation toward the fully closed position of the actuator while simultaneously engaging the engagement structure with respect to the engaged portion. It is advisable to install temporary supports in temporary positions where they will not fit.

The rotary shaft and the engagement structure are parallel to the connection object inserted into the insulator when the actuator has a rotary shaft rotatably supported by at least one of the contact and the insulator and the actuator is in the fully closed position. It is better to be on one plane.

The actuator has a rotational shaft rotatably supported by at least one of the contact and the insulator, and the contact constitutes a rotation shaft support groove for rotatably supporting the rotation shaft therebetween, which is substantially parallel to the direction in which the contact is inserted and removed. . It is preferable to have a supporting protrusion and a tail soldered to the electric substrate.

In this case, it is more preferable that the open end of the rotation shaft supporting groove is located on the opposite side to the direction of the removal of the connection object.

It is preferable that the actuator has a rotating shaft rotatably supported by at least one of the contact and the insulator, and the fixing metal part having a supporting recess for rotatably sandwiching the rotating shaft between the insulator to the insulator. .

In this case, it is preferable that the contact is soldered to an electric board parallel to the direction in which the connection object is pulled out, and the open end of the supporting recess is positioned on the electric board. good.

In the connector of the present invention, when the actuator is rotated to the fully closed position while the connection object is inserted into the insulator, the engagement structure of the actuator is fitted to the engaged portion of the connection object, and the actuator is held in the fully closed position by the locking holding means. As a result, the connection object is prevented from easily falling off the connector.

Furthermore, a window hole is formed in the actuator so that a flat surface (adsorption surface) formed on the surface of the insulator in the open position of the actuator is exposed through the window hole of the actuator. Therefore, in order to improve the operability of the actuator, it is possible to make the actuator as large as possible and to reliably transfer (adsorb) the connector in a stable state. That is, it is possible to provide a connector having excellent mounting failure prevention, operability and productivity.

In the invention according to claim 3, the actuator can be temporarily supported in the open position by fitting the actuator and the temporary support formed on one side of the insulator to the other side. In this way, the insulator is temporarily supported in the open position where the rotation angle to the fully closed position is small. By inserting the connection object into the and then rotating the actuator to the fully closed position, the connection object can be locked simply by rotating the actuator a little, so that the locking operation by the actuator can be easily performed even when the connector (and the actuator) is very small. .

If the actuator is in the fully closed position and the position of the actuator's rotational axis and the engagement structure deviate significantly from the direction orthogonal to the direction of the insertion and withdrawal of the object, the actuator will move toward the open position when a force is applied to the engagement structure. Rotation force (moment) is easy to occur. Therefore, if a force is applied in the direction of falling into the connection object in the state where the actuator is in the fully closed position, there is a fear that the actuator rotates toward the open position and the lock state is easily released.

However, the actuator configured as described in claim 4 is unlikely to generate a rotational force (moment) toward the open position when a force is applied in the direction of exit from the engagement structure at the engaged portion of the connection object in the state of being fully closed. Since the structure is less likely to be easily released, the actuator can be prevented from being damaged even if excessive force is applied to the engagement structure.

As the rotation shaft of the actuator is supported (capped) between the tail portion and the support projection portion firmly soldered to the electric substrate as in the invention of claim 5, the rotation shaft can be stabilized as mechanically as possible. Therefore, rotation axis shift or tilt does not occur, so excellent operation feeling can be obtained.

In addition, the resistance of the actuator is improved when the external force in the falling direction is loaded on the connection object locked by the actuator positioned in the fully closed position.

According to invention of Claim 7, it becomes possible to support the rotating shaft of an actuator in a more stable state.

In the case of claim 8, the open end is directed toward the electric substrate (in the direction in which the axis of rotation does not come off) to prevent the axis of rotation of the actuator from falling out and more stable support and behavior are possible. In particular, in the case of applying the present invention to the invention of claim 6, since the rotation shaft of the actuator is supported by the rotation shaft support grooves of the contacts having different positions of the open ends and the support recesses of the fixing metal parts, more significant effects can be obtained. have.

According to invention of Claim 9, the fixed state with respect to the electrical board of a connector becomes firm. Therefore, the rotating shaft of the actuator is supported by the supporting recesses of the fixing metal parts that are firmly soldered to the electric substrate, so that the rotating shaft can be mechanically stabilized as much as possible. Therefore, since the shift | offset | difference and the tilting phenomenon of a rotating shaft do not generate | occur | produce, the outstanding operational feeling can be obtained.

The front side of the contact support part 26 is connected to the back side of the front wall part 23, and the rear end is located ahead of the rear end of the left wall part 21 and the right wall part 22. As shown in FIG. In addition, a pair of arm portion insertion grooves 27 extending in the front-rear direction are formed between the left wall 21 and the right wall portion 22 and the left and right sides of the contact support portion 26. As shown, the second half 26A of the contact support 26 is wider in width than the first half 26B. In addition, the upper surface of the second half portion 26A is an adsorption surface (flat surface) 28 that is a flat surface located at the same position as the upper surface of the left wall portion 21, the right wall portion 22, and the front wall portion 23, The upper surface of the first half portion 26B is a plane located at the same position as the bottom surface of the fitting recessed portion 21A and the fitting recessed portion 22A. On the rear end surface of the contact support 26, five contact installation grooves 29 extending forward are formed side by side. One of the three contact mounting grooves 29 extends through the rear half 26A and the first half 26B and extends to the front wall 23, and the two contact mounting grooves 29 at the left and right ends have the rear half 26A. At the same time as it passes through, it extends to the front wall part 23 through the left and right both sides of the front part 26B. Moreover, in the middle part of the front part up-down direction of the front half part 26B, the recessed part 30 for FPC which passes the whole width of the front half part 26B is provided backward.

In the vicinity of the front end of the bottom (bottom 24) of the left and right arm insertion grooves 27, a pair of missing holes 31 is formed as a through hole, and a pair of metal parts is provided near the rear end of the bottom. The fixing part 32 is provided integrally. The upper surface of each metal part fixing part 32 is provided with metal part fixing holes 33 extending downward, and correspond to the metal part fixing parts 32 of the left wall part 21 and the right wall part 22. The side is formed with side recesses 34 in communication with corresponding metal part fixing holes 33, respectively. In addition, about halfway between the left wall portion 21 and the right wall portion 22 in the longitudinal direction, a lock retaining structure (locking means) 35 positioned immediately above the corresponding arm portion insertion groove 27 is provided. As shown in the figure, the upper surface of the lock holding structure 35 is a temporary holding inclined surface (temporary support) 36. In addition, the upper surface of the rear end of the bottom part 24 is a pair of left and right rotating shaft support surfaces 37 parallel to the suction surface 28.

The five contacts 40 respectively fitted to the contact mounting grooves 29 of the insulator 20 are obtained by stamping molding, and the substrates obtained by stamping molding (for example, bronze, beryllium copper, titanium copper, stainless steel). After base plating (for example, nickel (Ni) plating) on the corson-based copper alloy, finished plating (for example, gold plating, tin (Sn)-copper (Cu) plating, tin (Sn)-lead ( It is a material having elasticity and conductivity produced by Pb) plating).

Each contact 40 has an upper conduction arm 41 and a lower conduction arm 42 substantially parallel to each other at its front end, and correspond to each other at the distal ends of the upper conduction arm 41 and the lower conduction arm 42. Each of the contact protrusions 43 and the contact protrusions 44 protrudes. In addition, the rear end portion of the contact 40 is provided with a support portion 45 extending rearwardly and a tail portion 46 which is positioned directly below the support protrusion portion 45 and is substantially parallel to the support protrusion portion 45. have. As shown in the drawing, the tail portion 46 is longer than the support projection portion 45, and the support projection portion 45 and the tail portion 46 are formed as a rotation shaft support groove 47 having a lateral cross U-shape. If the tail portion 46 is longer than the supporting protrusion portion 45, the tail portion 46 is immediately visible in plan view, and thus, the connector 10 is mounted on the electric board CB, which is advantageous for image recognition for soldering confirmation. Do.

When each contact 40 is pressed (fixed) to each contact mounting groove 29 at the back of the contact support 26 (second half 26A), the tail portion 46 of each contact 40 is insulated from the insulator 20. Protrude downward from the lower surface (see FIGS. 8, 9, 10, etc.)

The rotary actuator 50 is injection molded of a heat resistant synthetic resin material.

The actuator 50 has a wider left and right width than the insulator 20 and has a substantially rectangular operation portion 51 in plan view, a pair of arm portions 52 extending from the rear end of the operation portion 51, and left and right arm portions ( A rear end connecting portion 53 extends in the left and right direction while connecting the rear end of the 52, and a window hole having a shape substantially the same as that of the suction surface 28 between the operation portion 51 and the arm portion 52 and the rear end connecting portion 53. (54).

As shown in the drawing, a pair of right and left engagement structures 55 protrude from the front end portion of the lower surface of the operation portion 51, and an engagement recess (locking holding means) is provided on the outer surface of the left and right arm portions 52 ( 56) is installed. The rear end connecting portion 53 is formed with a cylindrical shape extending in the left and right directions, and a rotation shaft 57 whose both ends are positioned outside the left and right arm portions 52 is integrally formed. In addition, five missing grooves 58 are formed in the rear-side connecting portion 53 side by side in the left-right direction.

As shown in FIGS. 3 and 7, the rotation shaft 57 of the actuator 50 is inserted into the rotation shaft support groove 47 of each contact 40 from the rear, and both left and right ends thereof are formed on the left and right rotation shaft support surfaces 37. It is in contact with the upper surface. In addition, the fixing projections 61 protruding in front of the fixing metal component 60 are pressed into the fixing parts 33 on the left and right sides, and the lower ends of the fixing projections 61 are insulated ( 20, protruding downward (see FIGS. 7, 8, 15, 18, and 21). The supporting recess 62 formed on the rear lower surface of the fixing metal part 60 has an axis of rotation from above. 57 is fitted to both left and right ends thereof, and the lower surface of the rear surface is in contact with the upper surface of the corresponding rotary shaft support surface 37. Thus, since the rotary shaft 57 of the actuator 50 is rotatably supported in the other direction by the left and right rotating shaft support surfaces 37 and the left and right fixing metal parts 60, the actuator 50 is the rotating shaft 57 Relative to the insulator 20 is rotatable. Specifically, the upper surface of the insulator 20 is exposed while being substantially orthogonal to the insulator 20, and the support projection 45 of each contact 40 is freely fitted into the corresponding recess groove 58 so as to be completely open. 3, 23, and the operation part 51 abuts on the fitting recess 21A and the fitting recess 22A while abutting the upper surface of the first half 26B, and the left and right arm portions ( 52 is fitted into the left and right arm insertion grooves 27, and the fully closed position in which the front end portions of the left and right engagement structures 55 fit into the left and right exit holes 31 of the insulator 20 (FIG. 4, 5, 6 and 20, 21, and 22 positions) can be rotated.

When the actuator 50 is positioned at the fully open position, both left and right ends of the flat stopper surface 53A (see FIGS. 2, 3, and 13) formed in the end surface of the rear end connecting portion 53 are arranged on the left and right rotation shaft support surfaces ( In contact with the upper surface of 37), the actuator 50 is regulated to be rotated back than the fully open position.

When the actuator 50 is rotated from the fully open position to the fully closed position, the outer edges of the lower surfaces of the left and right arm portions 52 abut the temporary support inclined surfaces 36 on the left and right sides of the insulator 20 (see FIG. 15). It is possible to hold the actuator 50 in the open position (temporary holding position) shown in Figs. 2 and 14 to 19. At this time, the actuator 50 is rotatable toward the fully open position, and cannot rotate toward the fully closed position unless an external force is applied to the actuator 50 in the fully closed position direction. On the other hand, when the actuator 50 is rotated toward the fully closed position with the force to elastically deform the lock holding structure 35 downward, the left and right arm portions 52 temporarily move the lock holding structure 35 downward while elastically deforming the lock holding structure 35. It jumps over the holding inclined surface 36 and rotates toward the fully closed position.

And when the actuator 50 rotates to a fully closed position, since the operation part 51 abuts on the upper surface of the front half part 26B (the actuator 50 covers the surface of the insulator 20), the actuator 50 will be lowered It is impossible to rotate. In addition, since the left and right lock retaining structures 35 are fitted to the engagement recesses 56 of the corresponding arm portions 52 (see FIG. 8), the external force is not applied to the actuator 50 in the fully closed position direction. Actuator 50 is maintained in a fully closed position. On the other hand, when the actuator 50 is rotated toward the fully open position with a force that elastically deforms the lock retaining structure 35 upward, the left and right engagement recesses 56 jump over the lock retaining structure 35. As a result, the actuator 50 is rotatable to the fully open position.

After the connector 10 of the above structure is assembled, the storage recess 72 of the embossing tape 71 wound around the reel device 70 shown in Figs. 24 and 25 with the actuator 50 positioned in the open position. ) Is stored. Since the upper cover tape 73 is attached to the upper surface of the embossing tape 71, the upper cover tape 73 must be peeled off the upper surface of the embossing tape 71 in order to remove the connector 10 from the storage recess 72. .

When the actuator 50 is located in the open position, the suction surface 28 of the insulator 20 is exposed through the window hole 54 of the actuator 50. (See FIG. 13) Thus, the embossing tape 71 A suction means 74 (see FIG. 25) provided above the upper portion of the connector 10 is positioned directly above the suction surface 28 of the connector 10, so that the suction force of the suction means 74 passes through the window hole 54. ), The suction surface 28 of the connector 10 is sucked by the suction port of the suction means 74, as shown by the solid line of FIG.

The suction means 74 is formed together with the connector 10 at a predetermined position on the electric substrate CB by using the driving force of the driving means (not shown), and the suction means 74 is transferred to the circuit pattern to which the solder paste is applied. Remove the suction force of the) and pile it up. The tail portion 46 of each contact 40 causes the circuit pattern on the electrical substrate CB and the ground pattern on the lower surface of the first half of the fixing metal part 60 and the ground pattern on the electrical substrate CB by passing the electrical substrate CB through the reflow. The lead paste is melted and solidified, respectively, and the connector 10 is mounted on the upper surface of the electrical substrate CB.

Next, the method of inserting the FPC 80 which is a connection object into the connector 10 of the above structure, and electrically connecting the FPC 80 and the electric board CB via the contact 40 is demonstrated.

As shown in FIG. 13, FIG. 14, and the like, cutout grooves (fitting portions) 81 are formed at left and right sides of the FPC 80 of the connector 10, respectively. In addition, the actuator 50 is located in the open position, which is the position when the tail portion 46 of the contact 40 and the fixing protrusion 61 of the fixing metal part 60 are soldered to the electric substrate CB.

13 to 16, the FPC 80 is positioned immediately before the FPC insertion hole 25 of the connector 10, and the rear end of the FPC 80 shown in Figs. When inserted into the inner space, the rear end of the FPC 80 is located between the contact protrusion 43 (upper conduction arm 41) and the contact protrusion 44 (lower conduction arm 42) of each contact 40 and the insulator ( 20 is entered into the recess 30 for FPC. When the contact 40 is in the free state, the distance between the contact protrusion 43 and the contact protrusion 44 is thinner than the plate thickness of the FPC 80, but the rear end of the FPC 80 is the contact protrusion 43 and the contact protrusion 43. When entering between the 44, the upper conductive arm 41 and the lower conductive arm 42 are elastically deformed slightly downward and upward, respectively, and the contact protrusions 43 and the contact protrusions 44 of the FPC 80 The upper and lower surfaces are in elastic contact with each other.

In this state, the FPC 80 is further pushed into the insulator 20 (moved backward), and the rear end of the FPC 80 shown in FIG. 19 is connected with the upper conduction arm 41 and the lower side of each contact 40. When the contact protrusion 43 and the contact protrusion 44 are elastically contacted with the conduction portions (not shown) formed on the upper and lower surfaces of the FPC 80, respectively, when reaching near the rear end of the gap between the conductive arms 42, The FPC 80 and the electrical substrate CB are electrically communicated through the contact 40. In addition, the left and right incision grooves 81 of the FPC 80 shown in FIG. 19 are located directly above the left and right exit holes 31 of the bottom part 24.

In this state, when the operation part 51 is pressed down and the actuator 50 is rotated to the fully closed position (refer FIG. 20, FIG. 21), the operation part 51 abuts on the upper surface of the front part 26B, and the fitting recess part ( 21A) and fitting recesses 22A, the left and right arm portions 52 fit into the left and right arm insertion grooves 27, and the left and right engagement structures 55 are cut grooves of the FPC 80. Since the fitting structure 55 fits into the insertion hole 31 of the 81 and the insulator 20 (see FIG. 22), the forward movement of the FPC 80 is restricted by the fitting structure 55.

When the FPC 80 is taken out of the insulator 20 due to maintenance or replacement of the module in the device, hold the left and right ends of the operation unit 51 protruding to the side of the insulator 20 in a planar view with a hand or a mechanism. The actuator 50 is rotated to the fully open position (see FIG. 23). Then, the engagement structure 55 of the actuator 50 is removed from the cutout groove 81 of the FPC 80, so that the FPC 80 can be pulled out of the insulator 20 to the front. In order to make the operation part 51 easy to grasp, it is preferable that the left and right widths of the operation part 51 be slightly wider than the insulator 20 to protrude.

As described above, the connector 10 of the present embodiment includes a rotary shaft support groove 47 in which the open ends of the five contacts 40 are located at the rear, and open ends of the two fixing metal parts 60, respectively. The rotation shaft 57 of the actuator 50 is firmly supported by the supporting recess 62, and the FPC 80 inserted into the insulator 20 by the engaging structure 55 of the actuator 50. By locking the, you can lock the FPC (80) with a high holding force as low as possible.

Moreover, since the open end is supporting the rotating shaft 57 of the actuator 50 by the rotating shaft support groove 47 of the contact 40 located in the back (as opposed to the direction in which the FPC 80 falls out), the actuator 50 ) Exhibits great resistance when an external force in the direction of exit from the FPC 80 is loaded.

However, when the actuator 50 is located in the fully closed position as shown in FIG. 22, the engagement structure 55 and the rotational axis 57 of the actuator 50 are located on one plane parallel to the FPC 80. If a force is loaded in the direction in which the FPC 80 falls out, and this force reaches the engagement structure 55 in the incision groove 81, the actuator 50 is less likely to generate a rotational force (moment) toward the fully open position. It is mechanically stable. Thus, even if an unintended external force in the direction of exiting (front) from the FPC 80 occurs, the FPC 80 cannot exit forward from the insulator 20.

In addition, since the size of the actuator 50 is as large as possible and approximately the same as that of the insulator 20, the operator can easily operate the actuator 50 even when the entire connector 10 is designed to be as small as possible. can do.

However, since the suction surface 28 of the insulator 20 is exposed through the window hole 54 of the actuator 50 regardless of the position of the actuator 50, the suction surface 28 is secured by the suction force of the suction means 74. Can be aspirated.

In addition, the inclined surface 36 (temporary support part) for temporary support of the insulator 20 allows the actuator 50 to be temporarily supported in an open position where the rotation angle to the fully closed position is smaller than that of the fully open position. After carrying out the packaging by the embossing tape 71, the adsorption by the suction means 74, and the mounting on the electric substrate CB, the FPC 80 is placed on the connector 10 with the actuator 50 in the open position. The FPC 80 can be locked by inserting it and then rotating the actuator 50 toward the fully closed position. Since the FPC 80 can be locked only by slightly rotating to the fully closed position, the actuator 50 positioned in the open position does not need to be returned to the fully open position once, so that the connector 10 (actuator 50) Even when the dimension is as small as possible, locking operation by the actuator 50 can be easily performed.

And since the actuator 50 has the rotating shaft 57 in the edge part (rear end part), compared with the case where the rotating shaft 57 is formed in the center part of the front-back direction of the actuator 50, it is engaged with the rotating shaft 57 The length of back and forth to 55 is long. Therefore, compared with the case where the rotation shaft 57 is formed in the center part of the actuator 50, the engagement structure 55 is enlarged in the thickness direction (up-down direction) of the connector 10 only by rotating the actuator 50 slightly. You can move it.

Moreover, since the connector 10 is accommodated in the embossing tape 71 in the state which positioned the actuator 50 in the open position, the connector 10 can be packaged in a stable state by the embossing tape 71. ( The actuator 50 does not rotate or the connector 10 does not move in the embossing tape 71.)

When the insertion state of the FPC 80 into the insulator 20 is incomplete, the engagement structure 55 of the actuator 50 located in the fully closed position and the position of the cutout groove 81 of the FPC 80 are Since it does not coincide, by moving the actuator 50 to the fully closed position, it is possible to easily determine during operation whether or not the insertion state of the FPC 80 is good.

Further, since the tail portion 46 and the fixing metal part 60 are soldered to the electric substrate CB longer than the support protrusion 45 formed on the contact 40, the fixed state of the connector 10 and the electric substrate CB is Very solid Therefore, it is possible to reliably prevent the rotation shaft 57 of the actuator 50 from being pulled out by the rotation shaft support groove 47 of the contact 40 and the support recess 62 of the fixing metal part 60. Stable support and behavior of the actuator 50 is possible.

As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to this embodiment, It can implement, making a various deformation | transformation.

For example, in the said embodiment, although the conducting part is formed in the upper and lower surfaces of the FPC 80, only the one side forms the conducting part, and the contact protrusion part 43 and the one of the contact protrusion part 44 contact this conducting part (conducting part). )

The rotary shaft 57 may be rotatably supported by the shaft bearing portion of the insulator 20 and the rotary shaft support groove 47 of the contact 40.

In addition, by adjoining the insulator 20 on the arm part 52 side, a temporary support part for temporarily supporting the actuator 50 in an open position is formed, or a temporary part that abuts each other in an upward direction of the insulator 20 and the arm part 52. You may form a support part.

In addition, by adjusting the engagement structure 55 of the actuator 50 longer than the illustrated embodiment, or by adjusting the position of the lock holding structure 35 (temporary support inclined surface 36), the actuator 50 Is positioned in the open position, the engaging structure that is pushed upward by the rear end of the FPC 80 when the FPC 80 inserted into the FPC insertion hole 25 is inserted into the distal end of the engaging structure 55. 55 lightly jumps over FPC 80. Then, when the insertion of the FPC 80 is completed, the actuator 50 automatically returns to the open position, and the temporary locking state in which the distal end portion of the engagement structure 55 is lightly caught by the incision groove 81 of the FPC 80 is Therefore, it is possible to prevent the FPC 80 from being pulled out until the transition to the fully locked state (locked state when the actuator 50 is located in the fully closed position).

Moreover, it is also possible to implement the missing hole 31 of the insulator 20 by the recessed part (non-through hole) formed in the upper surface of the bottom part 24. As shown in FIG.

In addition, instead of forming the incision groove 81 in the FPC 80, engaging holes (fitting parts located inward from the periphery of the FPC 80) through the FPC 80 in the plate thickness direction thereof are formed. You may form.

The connection object may be other than an FPC, for example, a flexible flat cable (FFC), a board or a leather strap.
