Description

  The present invention relates to a connector for electrically connecting a flat connection object such as a flexible printed circuit board (FPC) or a flexible flat cable (FFC) to an electric board.

The connector of Patent Document 1 includes an insulator (housing), a plurality of contacts fixed to the insulator, a fully open position (a position spaced apart from the insulator surface and substantially orthogonal to the insulator) and a fully closed position (insulator surface). And an actuator (rotating member) that is rotatably supported between the position and a position substantially parallel to the insulator. Further, the connection object (FPC) to be inserted into and removed from the connector is provided with a locking portion, while the actuator is provided with an engaging portion that can be engaged with the locking portion.
Therefore, when the actuator is rotated to the fully closed position after inserting the connection object into the housing with the actuator in the fully open position and electrically connecting with the contact, the engaging portion of the actuator is connected to the connection object. Therefore, the connection object is prevented from unexpectedly coming out of the connector (insulator).
JP 2006-114436 A

However, the connector of Patent Document 1 has the following drawbacks.
That is, when the connector structure of Patent Document 1 is applied to a very small connector (for example, the height is 1 mm or less and the longitudinal dimension and the short dimension are several mm), the actuator dimensions are also small. The nature will decline. Therefore, in such a case, it is desired to improve the operability of the actuator as much as possible by increasing the size of the actuator as much as possible (making the size of the actuator as close as possible to the size of the insulator).

However, when the size of the actuator relative to the connector is increased in plan view, most of the surface of the insulator is covered by the actuator when the actuator is located at the fully closed position. For this reason, a flat surface (so-called suction surface) to be sucked by the suction means when being transferred to the electric board on which the connector is mounted is formed on the surface of the actuator, not the insulator.
However, when 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 board. Therefore, the actuator is positioned at the fully closed position. Otherwise, the connector (actuator) cannot be transferred to the electric substrate by the suction means. Therefore, in order to connect the FPC or the like to the connector mounted on the electric board, it is necessary to move the actuator to the fully open position after mounting and then return it to the fully closed position, which increases the number of work steps.
Therefore, a large actuator in a small connector is advantageous from the viewpoint of operability, and is disadvantageous from the viewpoint of a suction surface to be transferred, which is a trade-off.

  The object of the present invention is to improve the operability of the actuator even when the connector is downsized, and is excellent in productivity that can be stably transferred by the suction means regardless of the position of the actuator. To provide a connector.

The connector according to the present invention includes an insulator capable of inserting and removing a flat connection object having a locked portion formed of a notch formed in a locking hole or a peripheral edge portion, and the above-described insulator fixed to the insulator and inserted into the insulator. From the surface compared to the fully closed position facing the surface and the fully closed position facing the insulator while being substantially parallel to the surface of the insulator and the contact electrically connected to the connection object An actuator having a locking claw that can be rotated to an open position to be separated and that can be engaged with the locked portion when positioned at the fully closed position, and an actuator positioned at the fully closed position are fully closed. Lock holding means for holding in position, a flat surface for transfer is formed on the surface of the insulator, and the actuator is attached to the actuator. It is characterized by forming the window hole for exposing the flat surface when located at the position and the open position.
When the actuator is located at the open position, the locking claw may be unable to engage with the locked portion.

  When at least one of the actuator and the insulator is engaged with the other when the actuator is in the open position, the rotation of the actuator to the fully closed position side is restricted and the locking claw is locked It is preferable to provide a temporary holding part that temporarily holds the part at a position where it cannot be engaged with the part.

  The actuator includes a rotation shaft that is rotatably supported by at least one of the contact and the insulator, and the rotation shaft and the locking claw are inserted into the insulator when the actuator is located at the fully closed position. It is preferable to lie on a plane parallel to the connection object.

The actuator includes a rotation shaft that is rotatably supported by at least one of the contact and the insulator, and both the contacts are substantially parallel to the insertion / removal direction of the connection target and rotate the rotation shaft between the two. It is preferable to include a support protrusion and a tail portion soldered to the electric board, which constitute a rotation shaft support groove for supporting the rotation shaft.
In this case, it is further preferable that the open end portion of the rotating shaft support groove is located on the side opposite to the drawing direction of the connection object.

The actuator includes a rotating shaft that is rotatably supported by at least one of the contact and the insulator, and a fixing bracket having a supporting recess that rotatably sandwiches the rotating shaft between the insulator and the insulator. It is preferable to fix.
In this case, it is preferable that the contact is soldered to an electric substrate parallel to the drawing direction of the connection object, and the open end of the supporting recess is located on the electric substrate side. It is even more preferable that the fixing bracket is soldered to the electric substrate.

In the connector of the present invention, when the actuator is rotated to the fully closed position with the connection object inserted into the insulator, the locking claw of the actuator engages the locked portion of the connection object, and the lock holding means Since the actuator is held in the fully closed position, it is possible to reliably prevent the connection target from unexpectedly coming out of the connector.
Further, since the actuator has a window hole, the flat surface (suction surface) formed on the surface of the insulator is exposed through the window hole of the actuator regardless of the position of the actuator. Therefore, even if the actuator is made as large as possible in order to improve the operability of the actuator, or the actuator is left in the open position in order to improve the productivity after mounting, the connector is reliably transferred in a stable state. It is possible to mount (adsorb). In other words, it is possible to provide a connector that is excellent in prevention of mounting defects and in operability and productivity.

  According to the third aspect of the present invention, the actuator can be temporarily held in the open position by engaging the temporary holding portion formed on one of the actuator and the insulator with the other. In this way, if the object to be connected is inserted into the insulator while temporarily held in the open position where the rotation angle to the fully closed position is small, and then the actuator is rotated to the fully closed position, the actuator is only slightly rotated. Since the connection object can be locked, even if the connector (and the actuator) is very small, the actuator can be easily locked.

If the actuator is in the fully closed position and the actuator's rotation axis and the position of the locking claw are greatly deviated in the direction perpendicular to the insertion / removal direction of the connected object, a force is applied to the locking claw. In addition, the actuator easily generates a rotational force (moment) toward the open position. Therefore, if a force in the pulling direction is applied to the connection target in a state where the actuator is in the fully closed position, the actuator may rotate to the open position side, and the locked state may be unexpectedly released.
However, the actuator configured as in the invention according to claim 4 moves to the open position side when a pulling direction force is applied from the locked portion of the connection object to the locking claw in the state of being in the fully closed position. Because it is difficult to generate the rotational force (moment), it is possible to reduce the possibility that the locked state will be released unexpectedly, and to prevent the actuator from being damaged even when excessive force is applied to the locking claw. is there.

According to the fifth aspect of the present invention, since the rotation shaft of the actuator is supported (clamped) between the tail portion firmly soldered to the electric substrate and the supporting projection, the rotation shaft is mechanically extremely It can be stabilized. Accordingly, since the rotational axis is not displaced or shaken, an excellent operational feeling can be obtained.
Further, the resistance force of the actuator is improved when an external force in the pulling direction is applied to the connection target locked by the actuator located at the fully closed position.
Further, when configured as in claim 6, the resistance force of the actuator is improved when an external force in the pulling direction is applied to the connection object locked by the actuator located at the fully closed position.

According to the seventh aspect of the present invention, the rotation shaft of the actuator can be supported in a more stable state.
When configured as in claim 8, since the open end portion faces the electric substrate side (in the direction in which the rotating shaft does not come off), it is possible to prevent the actuator from coming off the rotating shaft, and more stable support and behavior. Is possible. In particular, when the present invention is applied to the invention of claim 6, the rotation shaft of the actuator is supported by the rotation shaft support groove of the contact and the support recess of the fixing bracket, the positions of the open ends of each other being different. A more remarkable effect is obtained.

  According to the ninth aspect of the present invention, the connector is firmly fixed to the electric board. Therefore, since the rotating shaft of the actuator is supported by the supporting concave portion of the fixing bracket that is firmly soldered to the electric substrate, the rotating shaft can be mechanically extremely stabilized. Accordingly, since the rotational axis is not displaced or shaken, an excellent operational feeling can be obtained.

The front end of the contact support portion 26 is connected to the rear surface of the front wall portion 23, and the rear end is located in front of the rear ends of the left wall portion 21 and the right wall portion 22. Further, a pair of left and right arm receiving grooves 27 extending in the front-rear direction are formed between the left and right side walls 21 and 22 and the left and right side portions of the contact support portion 26. As illustrated, the rear half portion 26A of the contact support portion 26 is wider in the left-right width than the front half portion 26B. Further, the upper surface of the rear half portion 26A is an adsorption surface (flat surface) 28 that is a flat surface located at the same position as the upper surfaces of the left side wall portion 21, the right side wall portion 22 and the front wall portion 23, and The upper surface is a flat surface located at the same position as the bottom surfaces of the engaging recess 21A and the engaging recess 22A. On the rear end surface of the contact support portion 26, five contact mounting grooves 29 extending forward are formed side by side. The middle three contact mounting grooves 29 pass through the rear half portion 26A and the front half portion 26B and extend to the front wall portion 23, and the two contact mounting grooves 29 at the left and right ends pass through the rear half portion 26A and the front half portion 26B. It extends to the front wall 23 through the left and right sides. Further, an FPC recess 30 is provided in the middle of the front half 26B in the vertical direction on the front surface so as to extend rearward over the entire width of the front half 26B.
A pair of escape holes 31 are formed as through holes in the vicinity of the front end portion of the bottom surface (bottom wall portion 24) of the left and right arm receiving grooves 27, and a pair of metal fixture fixing portions 32 are formed in the vicinity of the rear end portion of the bottom surface. Are provided integrally. A metal fixing hole 33 extending downward is formed on the upper surface of each metal fixing part 32, and a corresponding metal fixing is provided in a part corresponding to each metal fixing part 32 of the left side wall part 21 and the right side wall part 22. Side recesses 34 respectively communicating with the holes 33 are provided. Further, a lock holding claw (locking means) 35 located directly above the corresponding arm portion receiving groove 27 projects from a substantially central portion in the longitudinal direction of the left side wall portion 21 and the right side wall portion 22. As shown in the drawing, the upper surface of the lock holding claw 35 is a temporary holding inclined surface (temporary holding portion) 36. Further, the upper surface of the rear end portion of the bottom wall portion 24 is a pair of left and right rotating shaft support surfaces 37 parallel to the suction surface 28.

The five contacts 40 that are respectively fitted into the contact mounting grooves 29 of the insulator 20 are integral parts obtained by stamping molding, and base materials (for example, phosphor bronze, beryllium copper, titanium copper) obtained by stamping molding are used. , Stainless steel, Corson copper alloy, etc.), after applying base plating (for example, nickel (Ni) plating), finish plating (for example, gold plating, tin (Sn) -copper (Cu) plating, tin (Sn)-) It is a member having elasticity and conductivity manufactured by applying lead (Pb) plating.
Each contact 40 includes an upper conductive arm 41 and a lower conductive arm 42 that are substantially parallel to each other at the front end thereof, and contact protrusions that face each other at the distal ends of the upper conductive arm 41 and the lower conductive arm 42. 43 and a contact projection 44 project from each other. Further, at the rear end portion of the contact 40, there are provided a support protrusion 45 extending rearward, and a tail portion 46 located immediately below the support protrusion 45 and substantially parallel to the support protrusion 45. is there. As shown in the drawing, the tail portion 46 is longer than the support protrusion 45, and a rotation shaft support groove 47 having a substantially U-shaped side surface is formed between the support protrusion 45 and the tail portion 46. If the tail portion 46 is longer than the support protrusion 45 in this way, the tail portion 46 can be directly viewed in plan view, which is advantageous for image recognition for confirming soldering after the connector 10 is mounted on the electric board CB. is there.
Each contact 40 is press-fitted (fixed) into each contact mounting groove 29 from the rear of the contact support portion 26 (second half portion 26A), and the tail portion 46 of each contact 40 protrudes downward from the lower surface of the insulator 20 (FIG. 8, FIG. 9, see FIG.

The rotary actuator 50 is formed by injection molding a heat-resistant synthetic resin material.
The actuator 50 connects the operation portion 51 having a substantially rectangular shape in plan view that is wider than the insulator 20, a pair of arm portions 52 extending from the rear edge portion of the operation portion 51, and the rear end portions of the left and right arm portions 52. A rear end connecting portion 53 extending in the left-right direction, and a window hole 54 having substantially the same shape as the suction surface 28 is provided between the operation portion 51, the arm portion 52, and the rear end connecting portion 53.
As shown in the figure, a pair of left and right engaging claws 55 project from the front end portion of the lower surface of the operation portion 51, and an engaging recess (lock holding means) 56 is recessed on the outer surface of the left and right arm portions 52. It is set up. The rear end connecting portion 53 has a cylindrical shape extending in the left-right direction and is integrally formed with a rotating shaft 57 whose both ends are located outside the left and right arm portions 52. Further, five escape grooves 58 are arranged in the rear end connecting portion 53 so as to be arranged in the left-right direction.
As shown in FIGS. 3, 7, etc., 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 in contact with the upper surfaces of the left and right rotation shaft support surfaces 37. ing. Further, a fixing protrusion 61 projecting from the front of the fixing metal fitting 60 is pressed into the left and right metal fixing holes 33 in a fixed state, and the lower end of the fixing protrusion 61 protrudes below the insulator 20. (See FIGS. 7, 8, 15, 18, and 21). The supporting recesses 62 formed on the lower surface of the rear portion of the fixing bracket 60 are engaged with the left and right ends of the rotating shaft 57 from above, and the lower surface of the rear portion contacts the upper surface of the corresponding rotating shaft support surface 37. ing. As described above, the rotating shaft 57 of the actuator 50 is supported by the left and right rotating shaft support surfaces 37 and the left and right fixing brackets 60 so as to be rotatable from different directions, so that the actuator 50 is attached to the insulator 20 around the rotating shaft 57. Relative rotation is possible. Specifically, the upper surface of the insulator 20 is exposed while being substantially orthogonal to the insulator 20, and the fully protruding position where the support protrusion 45 of each contact 40 is loosely fitted in the corresponding relief groove 58 (FIGS. 3 and 23). And the operating portion 51 engages with the engaging recess 21A and the engaging recess 22A while contacting the upper surface of the front half portion 26B, and the left and right arm portions 52 are fitted in the left and right arm portion receiving grooves 27, And the front-end | tip part of the right and left latching claw 55 can rotate between the fully closed positions (position of FIGS. 4-6 and FIGS. 20-22) which engages with the right and left escape holes 31 of the insulator 20.
When the actuator 50 is located at the fully open position, the left and right ends of the flat stopper surface 53A (see FIGS. 2, 3, and 13) formed on the end surface of the rear end connection portion 53 are the upper surfaces of the left and right rotating shaft support surfaces 37. Therefore, the actuator 50 is restricted from rotating backward from the fully opened position.
When the actuator 50 is rotated from the fully open position to the fully closed position, the outer edge portions of the lower surfaces of the left and right arm portions 52 abut against the left and right temporary holding inclined surfaces 36 of the insulator 20 (see FIG. 15). Can be temporarily held in the open position (temporary holding position) shown in FIGS. 2 and 14 to 19. At this time, although the actuator 50 can rotate to the fully open position side, it does not rotate to the fully closed position side 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 to the fully closed position with a force sufficient to elastically deform the lock holding claw 35 downward, the left and right arm parts 52 are temporarily held while elastically deforming the lock holding claw 35 downward. The vehicle passes over the inclined surface 36 and rotates toward the fully closed position.
When the actuator 50 rotates to the fully closed position, the operation unit 51 comes into contact with the upper surface of the front half portion 26B (the actuator 50 covers the surface of the insulator 20), so that the actuator 50 cannot rotate downward. Further, since the left and right lock holding claws 35 engage with the corresponding locking recesses 56 of the arm portion 52 (see FIG. 8), the actuator 50 is in the fully closed position unless an external force is applied to the actuator 50 in the fully open position direction. Retained. On the other hand, when the actuator 50 is rotated to the fully open position side with a force sufficient to elastically deform the lock holding claw 35 upward, the left and right locking recesses 56 get over the lock holding claw 35, so that the actuator 50 is moved to the fully open position. It can be rotated.

After the connector 10 having the above structure is assembled, the connector 10 is housed in the housing recess 72 of the embossed tape 71 wound around the reel device 70 shown in FIGS. 24 and 25 with the actuator 50 positioned at the open position. Since the upper surface cover tape 73 is stuck on the upper surface of the embossed tape 71, the upper surface cover tape 73 is first peeled off from the upper surface of the embossed tape 71 in order to take out the connector 10 from the housing recess 72.
When the actuator 50 is located at 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). Therefore, if the suction means 74 (see FIG. 25) disposed above the embossed tape 71 is positioned immediately above the suction surface 28 of the connector 10 and the suction force of the suction means 74 is applied to the suction surface 28 through the window hole 54. As shown by the solid line in FIG. 25, the suction surface 28 of the connector 10 is sucked into the suction port of the suction means 74.
The suction means 74 is formed at a predetermined position on the electric substrate CB together with the connector 10 by using the driving force of the drive means (not shown) and is sucked after being transferred onto the circuit pattern to which the solder paste is applied. The suction force of the means 74 disappears and the device is placed. Then, by passing the electric board CB through the reflow furnace, the tail portion 46 of each contact 40 and the circuit pattern on the electric board CB, and the lower surface of the front half of the fixing bracket 60 and the ground pattern on the electric board CB However, the solder paste is melted and solidified to be soldered, and the connector 10 is mounted on the upper surface of the electric substrate CB.

Next, a procedure for inserting an FPC (flexible printed circuit board) 80 as an object to be connected into the connector 10 having the above configuration and electrically connecting the FPC 80 and the electric substrate CB through the contact 40 will be described.
As shown in FIGS. 13 and 14, notches (locked portions) 81 are formed in the left and right side portions of the FPC 80, respectively. Further, the actuator 50 is positioned at an open position, which is a position when the tail portion 46 of the contact 40 and the fixing protrusion 61 of the fixing bracket 60 are soldered to the electric board CB.
When the FPC 80 is positioned just before the FPC insertion / removal hole 25 of the connector 10 as shown in FIGS. 13 to 16 and then the rear end of the FPC 80 is inserted into the inner space of the insulator 20 as shown in FIGS. The rear end portion of the FPC 80 enters between the contact projection 43 (upper conduction arm 41) and the contact projection 44 (lower conduction arm 42) of each contact 40 and into the FPC recess 30 of the insulator 20. When the contact 40 is in a free state, the distance between the contact projection 43 and the contact projection 44 is narrower than the thickness of the FPC 80, but when the rear end of the FPC 80 enters between the contact projection 43 and the contact projection 44, The upper conductive arm 41 and the lower conductive arm 42 are slightly elastically deformed downward and upward, respectively, and the contact protrusion 43 and the contact protrusion 44 are in elastic contact with the upper surface and the lower surface of the FPC 80, respectively.

From this state, the FPC 80 is further pushed into the insulator 20 (moved backward), and the rear end of the FPC 80 is the rear end of the gap between the upper conductive arm 41 and the lower conductive arm 42 of each contact 40 as shown in FIG. When reaching the vicinity, the contact protrusion 43 and the contact protrusion 44 are elastically contacted with conduction portions (not shown) formed on the upper surface and the lower surface of the FPC 80, respectively, so that the FPC 80 and the electric substrate CB are electrically connected via the contacts 40. Conductive. Further, as shown in FIG. 19, the left and right cutouts 81 of the FPC 80 are positioned immediately above the left and right relief holes 31 of the bottom wall portion 24.
In this state, when the operating portion 51 is pushed downward to rotate the actuator 50 to the fully closed position (see FIGS. 20 to 21), the engaging portion 21A and the engaging recess 21A are engaged while the operating portion 51 contacts the upper surface of the front half portion 26B. Since the left and right arm portions 52 are engaged with the left and right arm portion receiving grooves 27 and the left and right engaging claws 55 are engaged with the notches 81 of the FPC 80 and the escape holes 31 of the insulator 20 (FIG. The forward movement of the FPC 80 is restricted by the locking claw 55.

  When the FPC 80 is to be removed from the insulator 20 for maintenance or module replacement in the device, the left and right ends of the operation portion 51 protruding to the side of the insulator 20 in a plan view are gripped with hands or jigs. Then, the actuator 50 is rotated to the fully open position (see FIG. 23). Then, since the latching claw 55 of the actuator 50 is removed from the notch 81 of the FPC 80, the FPC 80 can be extracted forward from the insulator 20. In order to make it easier to grip the operation unit 51, it is preferable that the left and right widths of the operation unit 51 are slightly wider than the insulator 20 to protrude.

As described above, the connector 10 according to the present embodiment supports the rotary shaft support groove 47 in which the open ends of the five contacts 40 are positioned rearward and the open ends of the two fixing brackets 60 positioned downward. The rotary shaft 57 of the actuator 50 is firmly supported by the concave portion 62, and the FPC 80 inserted into the insulator 20 is locked by the latching claw 55 of the actuator 50. Can be locked with.
In addition, since the rotary shaft 57 of the actuator 50 is supported by the rotary shaft support groove 47 of the contact 40 whose open end is located rearward (opposite to the pulling direction of the FPC 80), the actuator 50 receives an external force in the pulling direction on the FPC 80. Exhibits great resistance when applied.
Moreover, as shown in FIG. 22, when the actuator 50 is located at the fully closed position, the engaging claw 55 and the rotation shaft 57 of the actuator 50 are located on a single plane parallel to the FPC 80. Even when this force is applied from the notch 81 to the locking claw 55, the actuator 50 is hardly mechanically stabilized because a rotational force (moment) toward the fully open position is hardly generated. Therefore, even if an unintended external force in the pulling direction (forward) is applied to the FPC 80, the FPC 80 does not come out of the insulator 20 forward.
Furthermore, since the size of the actuator 50 is made substantially the same as that of the insulator 20 in order to make it as large as possible, the operator can easily operate the actuator 50 even when the entire connector 10 is designed to be extremely small. .
Moreover, 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 can be reliably suctioned by the suction force of the suction means 74.

Further, the temporary holding inclined surface 36 (temporary holding portion) of the insulator 20 can temporarily hold the actuator 50 at the open position where the rotation angle to the fully closed position is smaller than the fully open position. , Packing by the suction means 74, and mounting on the electric board CB, the FPC 80 is inserted into the connector 10 with the actuator 50 in the open position, and then the actuator 50 is rotated to the fully closed position side. By doing so, the FPC 80 can be locked. In this way, it is not necessary to once return the actuator 50 located at the open position to the fully open position side, and the FPC 80 can be locked only by rotating it slightly to the fully closed position, so that the size of the connector 10 (actuator 50) is extremely small. Even so, the locking operation by the actuator 50 can be easily performed.
In addition, since the actuator 50 includes the rotation shaft 57 at the end (rear end), compared to the case where the rotation shaft 57 is formed at the center in the front-rear direction of the actuator 50, the locking claw 55 extends from the rotation shaft 57. Long before and after. Therefore, compared with the case where the rotation shaft 57 is formed in the central portion of the actuator 50, the latching claw 55 can be moved in the thickness direction (vertical direction) of the connector 10 only by slightly rotating the actuator 50. It is.
Further, since the connector 10 is housed in the embossed tape 71 with the actuator 50 positioned at the open position, the connector 10 can be packed in a stable state with the embossed tape 71 (the actuator 50 rotates in the embossed tape 71, The connector 10 does not roll).

Further, when the insertion state of the FPC 80 with respect to the insulator 20 is incomplete, the position of the locking claw 55 of the actuator 50 located at the fully closed position and the position of the notch 81 of the FPC 80 do not coincide with each other, and therefore the actuator 50 is moved to the fully closed position. Thus, it can be easily determined during the operation whether or not the insertion state of the FPC 80 is good.
Further, since the tail 46 longer than the support protrusion 45 formed on the contact 40 and the fixing bracket 60 are soldered to the electric board CB, the fixing state of the connector 10 and the electric board CB is extremely strong. . Accordingly, the rotation shaft support groove 47 of the contact 40 and the support recess 62 of the fixing bracket 60 can reliably prevent the rotation shaft 57 of the actuator 50 from coming off, and the actuator 50 can be stably supported and behaved.

As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to this embodiment, It can implement, giving various deformation | transformation.
For example, in the above embodiment, the conductive portions are formed on the upper and lower surfaces of the FPC 80, but the conductive portion is formed only on one surface, and one of the contact protrusion 43 and the contact protrusion 44 is in contact with this conductive portion ( Conduction).
Further, the bearing portion of the rotating shaft 57 of the actuator 50 may be formed in the insulator 20, and the rotating shaft 57 may be rotatably supported by the bearing portion of the insulator 20 and the supporting recess 62 of the fixing bracket 60. Further, the rotating shaft 57 may be rotatably supported by the bearing portion of the insulator 20 and the rotating shaft support groove 47 of the contact 40.
Furthermore, a temporary holding portion that temporarily holds the actuator 50 in the open position by contacting the insulator 20 on the arm portion 52 side is formed, or a temporary holding portion that contacts both the insulator 20 and the arm portion 52 is formed. Also good.

Further, the actuator 50 is positioned at the open position by making the locking claw 55 of the actuator 50 longer than that of the illustrated embodiment or by adjusting the position of the lock holding claw 35 (temporary holding inclined surface 36). Sometimes, the tip of the locking claw 55 may be positioned at the same height (on the same plane) as the FPC 80 inserted into the FPC insertion / removal hole 25. In this way, when the FPC 80 is inserted into the insulator 20 while the actuator 50 is temporarily held at the open position, the locking claw 55 pushed upward by the rear end of the FPC 80 gets over the FPC 80 lightly. When the insertion of the FPC 80 is completed, the actuator 50 returns to the open position by its own weight, and the tip of the locking claw 55 is lightly hooked on the notch 81 of the FPC 80, so that the full lock state (the actuator 50 is in the fully closed position). The locking of the FPC 80 can be prevented until it shifts to the locked state when it is positioned at (5).
Further, the escape hole 31 of the insulator 20 can be implemented as a recess (non-through hole) formed in the upper surface of the bottom wall portion 24.
Furthermore, instead of forming the notch 81 in the FPC 80, a locking hole (a locked portion positioned inside the peripheral edge of the FPC 80) that penetrates the FPC 80 in the plate thickness direction may be formed.
Further, the connection object may be other than the FPC, for example, a flexible flat cable (FFC), a substrate, or a harness.
