Abstract

The purpose of the present invention is to prevent actuator twisting or other deformation during a movement operation and to enable an easy and reliable electrical connection by facilitating check of the operation state of the actuator, and to do so using a simple structure. Inclined surface portions (12b1) are formed at both ends in the longitudinal direction of the end surface in the rotational radial outward direction of an actuator (12) that holds or releases a signal transmission medium (F). All of the pressing force applied by an operator is caused to act substantially uniformly on the entire length of the actuator (12), thereby preventing a situation where the actuator (12) is pressed while being twisted. As a result, the action of holding the signal transmission medium (F) can be effectively carried out, and the rotation state of the actuator (12) can be visually checked easily and reliably.

Description

201236281 VI. Description of the Invention: [Technical Field of the Invention] This U is an electrical connection number for constructing a fixed transmission medium by moving an actuator. [Prior Art] Tongmu's in various electrical machinery and the like, with flexible printed circuits (Fpc,

Pdnted (five) or flexible (four) Ping Weiqing, Flexible

FlatCable) and the like are widely used as electrical means for various electrical connectors. For example, the following Patent Document 1 is attached to a printed wiring board and used as an electrical connection. The signal transmission medium made of Fpc or FFC is inserted into the front end (four) of the blank (series). The internal 'in the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Push it down and turn it. Further, if the actuator (connection operation means) is rotated to the "connection action position" of the clamp signal transmission medium, the cam member provided on the carrier presses the conductive contact n' thereby thereby contacting the t contact to crimp The money transfer medium (FPC, FFC, etc.) is shifted and fixed signal transmission medium is performed. On the other hand, if the actuator located at the "connection action position" is turned toward the original "connection release position" and lifted upward, for example, upward, the conductive contactor is self-repulsive by its own elastic restoring force. The transmission medium (Fpc, FFC, etc.) is shifted in the direction of the opening of 100127696 201236281, so that the signal transmission medium is formed in an open state. The actuator of the electrical connector has a configuration between the "connection release position" and the "connection avoidance", for example, by rotating the center of rotation of the actuator extending in the longitudinal direction The sister moves to operate. However, in recent years, as the overall size of the electrical connector has been continuously increased, the actuation of the forest body has been reduced in size and thickness, and the rigidity has been lowered. This causes, for example, the following problems. In other words, if the actuator whose rigidity is reduced by miniaturization or thinning is biased toward the operating force in the direction of the longitudinal direction of the actuator, the actuator as a whole may be twisted and deformed. The partial conductive connection (4) transmits the original (four) force, and becomes a state in which the conductive contactor cannot be crimped and connected to the signal transmission medium (FPC, FFC, etc.). Moreover, as the entire connector and the actuator are miniaturized, it is also visually difficult to recognize where the actuator is rotated, in particular, the state in which the actuator is rotated to the "connection position", and confirmation is made. The connection state of the conductive contactor becomes a problem. [Prior Art Document] [Patent Document] Patent Document 1: JP-A-2004-71160 SUMMARY OF INVENTION [Problems to be Solved by the Invention] Therefore, the object of the present invention is to provide a simple configuration. It is possible to prevent deformation such as twisting of the actuator during the moving operation, and it is possible to easily confirm the operational state of the actuator 100127696 4 201236281, and the electrical connector that can be electrically connected easily and surely. Means for Solving the Problems In order to achieve the above object, the present invention is an electrical connector which is provided with an actuator for holding or opening a signal transmission medium so as to be rotatable about a rotation center extending in a longitudinal direction of the actuator The outer circumference side end surface in the radial direction of the rotation center of the actuator and the both end portions of the longitudinal direction of the dynamic direction are provided to form an appropriate shape for the long side direction. An inclined face that extends at an angle. According to the invention including the above configuration, in order to rotate the actuator from the "connection releasing position" to the "connection working position", for example, the vertical wall surface of the actuator in the state t of the "connection releasing position" is established. When the operator presses the fingertip of the operator, the fingertip of the operator is difficult to act on the inclined surface provided in the longitudinal direction (fourth). Therefore, the pressure is applied to the central portion of the longitudinal direction of the actuator. The pressing force applied to the inclined surface portions at both end portions in the longitudinal direction also faces the inclined surface of the inclined surface portion at a substantially right angle, and acts toward the center side at both end sides in the longitudinal direction of the actuator. Therefore, the operation pressure added by the operator has a tendency to become a uniform function of the _ thief, and it is not easy to happen as in the case of pressing the actuator in the state: The actuator as a whole maintains a substantially flat surface = 仃 rotation, so that the central role of the medium can be well exerted. The rotation of the air is transmitted to the signal transmission 100127696 201236281 and further, 'the shape of the inclined face is arranged at both ends of the longitudinal direction including the actuator'. When observing the appearance of the actuator, the entire temple is visually recognized as including The characteristic shape of the trapezoid is such that the rotational state of the actuator can be easily and surely confirmed visually. Further, in the present invention, a portion of the inclined surface portion of the (fourth) portion provided in the longitudinal direction is provided in a flat surface extending in the longitudinal direction, and the inclined surface is formed from the long side of the flat (four) The direction _ section can be connected smoothly, so it is better. According to the invention including such a configuration, when an operation force is applied to the actuator, since the corner portion where the stress gathers on the boundary portion between the inclined face portion and the flat face portion is no longer present, the rotation of the actuator can be prevented. The disruption caused by the operation. ' ^ ; In the present month, both end edges in the longitudinal direction of the actuator are respectively arranged to extend substantially in a plane along the direction of the radius of rotation of the actuator ==, from which the wall faces are raised It is preferable that the outer end edge is connected in the direction of the turning radius, and the shell 5 is placed on the inclined surface. According to the present invention including such a configuration, the rigidity of the movable body is increased as compared with the case where the rising face is not provided, and the degree of damage to the actuator can be increased. Further, in the present invention, the angle of the inclined surface portion to the longitudinal direction is set to four. To 15. The range is good. According to the present invention having such a configuration, it has been found that both of the operation force of the entire length of the actuator and the rigidity of the entire length of the actuator when the actuator is actuated 100127696201236281 can be satisfactorily obtained. . Further, the inclined surface portion according to the present invention is attached to an operation avoiding assisting portion which is formed from the inclined surface which is adjacently disposed along the inclined surface portion, and the operation avoiding assisting portion is from the inclined surface to the edge The erected soil surface in which the rotation half of the actuator extends in a direction and extends substantially in a plane along the longitudinal direction of the actuator. It is preferable that the outer edge of the radial direction of the P is formed with an appropriate angle and extending with respect to the rotation half t direction of the actuator. According to the present invention including the above configuration, as described above, the fingertip of the operator tends to be less likely to act on the inclined face during the operation of the actuator, and the operation avoidance assisting portion provided in the inclined face becomes additional. More significant, therefore, the operation added by the operator can function more uniformly over the entire length of the pressing force, and is less likely to be pressed if the actuator is twisted, and the overall benefit can be maintained substantially flat. Rotation is performed so that the clamping action of the rotation of the actuator on the signal transmission medium can be performed extremely well. Further, in the invention, the operation avoidance assisting portion is configured to face the operation force attached to the actuation II when the actuator is operated in a clamping direction from a state in which the signal transmission medium is opened. This is better. - Subtracting the present invention including such a configuration, it is difficult to act on the fingertip of the operator with respect to the inclined surface when the riding is performed in the direction of the scale. Also in the present invention, along the direction of the radius of rotation of the actuator and along the actuation angle. The long side of the rising wall surface extending in a substantially planar direction in the longitudinal direction 100127696 201236281 The central portion of the direction is a portion in which the state of the signal transmission medium is opened to the direction of the clamping force or the signal transmission medium is self-clamped. In the position where the operation force is added in the direction of opening, the operation support portion including the concave portion or the convex portion extending in the longitudinal direction of the actuator is provided, which is preferable as the concave portion of the operation support portion or It is preferable that the convex portion is formed in a shape that can engage the tip end portion or the nail portion of the operator of the above actuator. According to the present invention including the above-described configuration, when the actuator is operated, the nail portion or the finger tip portion of the operator of the actuator easily acts on the operation support portion in the center portion in the longitudinal direction, and the center of the actuator The portion can positively receive the operation pressing force attached by the operator and surely obtain uniform operability. Further, in the invention, it is preferable that the operation support portion is formed to extend in a curved shape or a straight line along the longitudinal direction of the actuator. According to the present invention including the above-described configuration, the operator's fingertip portion is easily and surely engaged with the button portion, and the fingertip portion of the shooter is easily and reliably positioned, and the operation support portion is surely engaged. Therefore, it is possible to obtain a good operability by appropriately arranging the curved or straight-aged portion of the age range, and the operability of the present invention is as follows: An end face in the longitudinal direction of the end face on the outer side of the radius of rotation of the actuator for holding or opening the signal transmission medium is provided with an inclined face portion so that the total pressing force of the actuator is the total length of the actuator It acts substantially uniformly, which can eliminate the situation in which the actuator is pressed in the twisted state 100127696 201236281, and the clamping action of the signal transmission medium is performed well 'and the rotational state of the actuator is visually easy and sure Since the ground is confirmed, it is possible to prevent deformation such as distortion of the actuator during the movement operation in a simple configuration, and it is possible to easily and surely perform electrical connection by confirming the operation state of the actuator, which is inexpensive and large.

The lower terminal contact convex portions 13b1 and 14b1 may be arranged such that their positions are shifted toward the connector front side (the left side in FIG. 1A) or the connector rear side (the right side of the figure). Further, the fixed beams 131) and 141) are substantially fixed in a non-moving state, but in order to facilitate the insertion of the signal transmission medium (Fpc or the like) F into the valley, the front end portion may become a bulletable 100127696 201236281. Alternatively, the front end portions of the fixed beams 13b, 14b may be formed to slightly float from the inner wall surface of the bottom panel of the insulating casing 11. Further, on the end side portion (the right end side portion of FIG. 1A) of the fixed beam 13b and the front end side portion (the left end side portion of FIG. 1A) of the fixed beam 14b, solder joints are respectively formed to be formed in the main printing. The board connecting portions 13b2 and I4b2 of the wiring circuit on the wiring board (see the symbol P in FIGS. 12 and 13).

The cam receiving recesses 13b3, 14b3 which are recessed shapes are respectively provided. The cam supporting portions I3a2, 14a2 and the cam receiving recesses 13b3, 14b3 are in contact with the pressing cam portion 12a of the actuator (connection operating means) 12 disposed at the rear end portion of the insulating casing 11. The cam surface formed along the outer circumference of the pressing cam portion 12a is slidably brought into contact with the cam receiving portions 13a2, 14a2 of the movable beams 13a, 14a and the cam receiving recesses i3b3, 14b3 of the fixing beams 13b, 14b. In the contact arrangement relationship, the actuator 12 is rotatably supported by the rotation center X (refer to Figs. 10 and 11) of the pressing cam portion 12a. • At this time, the cam supporting portions I3a2, 14a2 of the movable beams 13a, 14a are And the cam receiving recesses 13b3 and 14b3 of the fixed beams 13b and 14b are configured to lightly fit the pressing cam portion 12a that is rotated to the "joining position" as shown in Fig. 2, and are held to rotate the pressing cam portion 1 The state of the "connection position" to the figure. 100127696 13 201236281 On the other hand, the actuator that is configured to rotate to the rear end portion of the insulating casing u (the right end portion of Figs. 1A and 11) The whole of the "connecting hand & 12" 12 is formed so as to extend over the longitudinal direction of the connector, and the entire width of the peripheral peripheral 11 is substantially the same. The The center of rotation of the longitudinal direction of the device 12, that is, the center of rotation of the pressing cam portion i2a (which is rotatably mounted around the periphery of FIG. 1A and FIG. 1) and the portion other than the radius of rotation of the center of rotation (the right end side portion of Fig. 11) becomes the switch operation portion i2b. Further, by giving the operator an appropriate operation force to the switch material 12b, the whole crying 12 can be activated. The secluded position is reciprocally rotated between the connection position "in a state where the connector is substantially horizontally collapsed toward the rear side of the connector as shown in Fig. 11." At this time, the portion of the switch operation portion 12b that is coupled to the pressing cam portion 12a is formed. In the above, a slit-like through-hole portion 有用 that is used to avoid interference with the conductive contactors 13 and 14 is formed, and when the actuator 12 is rotated to the "connection releasing position" (see FIG. 1A), the conductive contact is formed as described above. The rear end portions of the movable beams ..., 14a of the tubes 13 and 14 are inserted into the inside of the slit-shaped through-hole portion 。. On the other hand, the switch operation portion 12b of the actuator (connection operation means) 12 is operated by the operator. ^ a from "connection release bit (Refer to the "coupling position") (the rotation of the pressing cam portion 12a is configured to be along the fixed display, (10) and the movable beam 13a, 14a toward the "joining action position" (see FIG. In addition, as the diameter of the cam portion 12a increases, the cam support portions 13a2, 14a2 provided on the rear end sides of the movable beam i3a, ΐ4 & When it is lifted up and displaced, the terminal contact convex parts 13a1 and 14al are pressed downwards on the opposite side (connector side) of the cam support parts 13a2 and 14a2. When the actuator (connection operation means) 12 is completely rotated to the "connection action position" as the final rotation position (see FIG. u), the terminal contact protrusions i3a1, 14al and the fixed beam 13b are formed on the movable beam 13a, 14a. The terminal contact convex portion 13b under the 14b is pressed from the upper and lower sides to the signal transmission medium (FPC or FFC, etc.) inserted between the two, thereby performing the clamping of the signal transmission medium F. At this time, it is configured as a pair. The wiring pattern (signal transmission and shielding guide circuit) Fa of the signal transmission medium F is electrically connected by crimping the upper terminal contact convex portions 13a1 and 14a1 and the lower terminal contact convex portions 13M and 14b1. As described above, the actuator 12 is rotated from the "connection release position" (see FIG. 10) to the rear side to be rotated and moved to the "connection action position" (see FIG. 11). The lower side portion of the switch operation portion 12b is disposed close to the main wiring substrate p, but the lower portion of the switch operation portion 12b of the actuator 12 is protruded toward the main wiring substrate at this time. Projection 12d The protective protrusion i2d is formed in a plurality of blocks at a predetermined interval in the direction in which the plurality of conductive contacts 13 and 14 are arranged (longitudinal direction of the connector), and is formed into a substantially quadrangular column. Each of the protection protrusions 12d is configured to integrally rotate the β=body as the actuator 12 100127696 15 201236281 rotates, and each of the protection protrusions 12d is disposed in the longitudinal direction of the connector, that is, the conductive contact 13 The position of the conductive contactor 14 having the shape of the upper private side recorded in the direction of the multipole of 14 is the substrate connection of the conductive contactor 丨3 having the shape of the adjacent side in the direction of the equator. P 13b2, 13b2 are portions between each other. Thus, when the protection protrusion (3) and the actuator 12 are integrally rotated, the state in which the substrate connection portion 13b2 of the conductive contactor 13 on one side is not disturbed is maintained. Further, the conductive contact 14 having the shape of the other side is disposed at a position corresponding to the rear side of the conductive contact 14 (the right side of FIG. 6) and does not rotate with the respective protection protrusions 12d. Within the inner side of the radius The position where the surface 12dl is disturbed, that is, the inner end surface 12 of the protection protrusion 12d in the state where the actuation II 12 is in the "connection position" (Π, configured to face the conductive contact 14 from the other side) The rear end surface (the upper surface of the cake surface) 14b4 of the fixed beam 14b is slightly spaced apart from the rear side (the upper side of FIG. 17), and the pair of end faces are spaced apart from each other to maintain the alignment relationship. The conductive contactor 14 on the other side does not interfere with the state. Further, the rear edge portion (the upper edge portion of FIG. 17) of the bottom panel of the insulating case 11 of the other side of the conductive contact 14 is held as a connector. The position in the front-rear direction (the horizontal direction in FIG. 16) is substantially aligned with the rear end surface (the upper end surface of FIG. 17) 14b4 of the other side of the conductive contactor 14. Therefore, the inner end surface 12d1 of the protective projection 12d is also disposed to face the rear side (the upper side of FIG. 17) with respect to the rear edge portion of the bottom panel of the insulating case (the upper edge portion of FIG. 100127696 201236281 17). The slightly spaced position allows the non-interference state of the respective protection protrusions 12d of the insulating case 11 to be maintained by the arrangement of the end faces spaced apart from each other. Further, each of the protective projections 12d is provided on the outer end surface 12d2 on the outer side of the turning radius, and is disposed on the outer side of the operating side on the outer side of the same turning radius from the switching operation portion 12b of the actuator 12 (Fig. 10). And the right end surface of FIG. 13 is slightly introduced to the inner side (the left side of FIG. 1 and FIG. 13), and the end surface 12d2 of the protection protrusion σΡ 12d is disposed to be a switching operation portion with respect to the actuator 12. The outer side end of the operating side of 12b is formed to form a step. Further, as shown in Fig. 13, in particular, the nail S of the operator is easily caught by the step formed by the protective projection 12d from the lower side and the portion from the step to the outer side of the turning radius. The outer end surface 12d2 of the protective protrusion 12d having the step is disposed on the end surface (the right end surface of FIGS. 10 and 13) of the substrate connecting portion I3b2 of the conductive contact 13 provided on the one side. The rear side of the 12th side (the right side of FIG. 1A and FIG. 13) is a position slightly protruding toward the operation side outer end surface side of the actuator 状态 in a state where the actuator 12 is moved to the "connection action position". Therefore, when the operator's nail S is inserted into the connector inner side (the left side of FIG. 13), the operator's finger S abuts against the outer end surface 12d2 of the protection protrusion 12d, so the operator's finger The 曱S does not contact the substrate connecting portion 13b2 of the conductive contactor 13. 100127696 201236281 In addition, since the nail s of the operator abuts against the above, when the actuator 12 is released from the end face 12d2 of the resisting portion (3), the operator's fingering position "turns" to "connect λ". 5 does not enter from the outer end surface 12d2 to the side of the pressing cam portion 12a, and does not contact the conductive contact (4) of the movable contact beam 13a, 14a protruding from the slit-shaped beacon hole portion 12c of the actuator 12. Thus, the gap formed between the actuator 12 and the main printing package is caused by the protective projections provided on the actuator 12 and from the rear side of the actuator 12 (right of FIG. 13). The square side cover does not come into contact with the nail member S of the connector part such as the Ai Du $ electrical contact S 13 , 14 disposed on the inner side of the gap between the actuator 12 and the main printed wiring board P Further, since the protective protrusion is provided as a step on the outer side surface of the operation side of the actuator actuator (3), when the actuator Μ 2 is operated, the finger of the "footer" (four) 姊 姊 与The step (') of the dog portion (3) is protected to safely and surely actuate the rotation operation of $η. Further, since the protective projections 12d are disposed between the substrate connecting portions 13b2 and 13b2 adjacent to each other in the direction in which the plurality of poles are arranged, the actuator 12 is moved to the "connecting action". ^ When the position is used, the protective protrusion (3) of the actuating Jie 12 prevents the dry L of the two in the direction of arrangement with the multipole by entering the portion of the substrate of the conductive contact 13 and tearing each other The conductive contact is crying. Even if the actuator is shortened in the long-side direction, interference does not occur, and the substrate connection portions 13b2, 13b2 of the conductive contactor u 100127696 18 201236281 ▲ are borrowed from each other (4) i2 is covered by the dog 12d. Therefore, it is a situation in which foreign matter such as dust is prevented from entering the portion to be electrically short-circuited. Further, since the protective projection (3) is disposed so as to protrude from the rear end of the substrate connecting portion of the conductive contact 13 facing the operator side of the actuator 12, the front end of the operator's nail s contacts the actuator 12 The protrusion (3) can not be inserted into the step further, so that the front end of the operator's nail S can be reliably prevented from being connected to the end surface of the substrate connection portion of the conductive contactor 13 by the tipping portion (3) The flank does not interfere with the insulating housing U in the reciprocating direction of the _12, so there is no need to reduce the insulating housing U in order to avoid interference with the protective projection 12d of the actuator 12, thereby making the conductive contact 13 The retention of 14 is maintained as good. On the other hand, as described above, the switch operation portion ub of the actuator 12 is extended in the longitudinal direction of the connector (4), but is outside the radial direction of the rotation of the _off operation portion 12b. On the end surface of the operation side, that is, the upper end surface of the actuator 12 is erected in the "connection release position" (refer to FIGS. 4 and 5), and the inclined surface portion 12M is respectively provided at both end portions in the longitudinal direction of the connector. . The inclined faces are formed to descend toward the outer side of the longitudinal direction of the connector, that is, the extending direction of the actuator 12, and are formed to extend at an appropriate angle to the longitudinal direction of the connector. Further, a portion of the two inclined surface portions 12b is formed in a strip shape and is provided with a flat surface portion 12b2 extending along the actuator. The length direction of the connector extending in the direction of 12 is extended at an appropriate angle with respect to the longitudinal direction of the connector, that is, the angle of inclination of the downward direction of the water obtained by extending the flat face, In the embodiment, it is set to 4. To the extent of... When (4) is set to such an inclination angle, when the actuator 12 is actually rotated, the uniformity of the operation pressing force for the entire length of the actuator 12 and the total length of the actuator 12 can be well obtained at the same time. Further, both of the rigid portions, the inclined surface portions 12b1 and 12b1 disposed on the both end sides in the longitudinal direction of the connector are formed by smoothly connecting the both end portions of the flat surface portion 12b2 provided on the center side in the longitudinal direction of the connector, and The boundary portion between the two face portions 12b1 and 12b2 is not formed with a corner portion. Further, both end edge portions ' of the switch operation portion 12b provided in the actuator 12 in the longitudinal direction of the connector are provided with both end side standing wall surface portions 12b3 which are formed in a substantially planar shape. The %·each end side rising wall surface portion 12b3 is formed to extend in the direction of the rotational radius of the actuator 12. In other words, in a state in which the actuator 12 is placed in the "connection releasing position" (see FIGS. 4 and 5), the wall surface portion 12b3 rises from the upper end sides of the insulating casing 11 toward the substantially vertical upward direction. The inclined surface portion 12b1 is connected to the upper end portion of each of the both end side standing wall surface portions 12b3. In the present embodiment, since the inclined surface portions 12b1 are provided at both end portions of the switch operating portion 12b of the actuator, the following advantages can be obtained. In other words, when the actuator 12 is rotated from the "connection release position" to the "connection action position", the fingertip of the operator causes the actuator 12 to stand up in the "connection release position" (refer to FIG. 10). The front side of the front end surface (the left end surface of FIG. 1 is raised). The wall surface is pressed toward the rear side. However, if the inclined surface portion 12M is provided at both end portions of the switch operation portion 12b of the actuator 12 as described above, the operation is performed. The pressing force of the person is hard to act on the portion of the inclined surface portion 12b1 provided on both end sides in the longitudinal direction, and the pressing force is added to the central portion of the longitudinal direction of the actuating jewel 12. On the other hand, the pressing force applied to the inclined surface portion 12 on both sides in the longitudinal direction of the actuator 12 is attached to the direction of the substantially inclined angle with respect to the inclined surface constituting the inclined surface portion 12A. Both ends of the longitudinal direction of 12 function toward the center side. Therefore, as a whole of the pressing force of the operator, the entire length of the actuation H 12 acts substantially uniformly, and the state in which the actuator 12 is pressed in a state of being bent is not conventionally actuated by actuation. The whole of the device 12 is rotated substantially in a plane, so that the clamping action of the rotation of the actuator 12 on the signal transmission medium (FPC, FFC, etc.) F can be satisfactorily exhibited. Further, when observing the overall appearance of the actuator u, especially as indicated by the two-dot chain line indicated by the symbol A in Fig. 7, it is visually recognized as having a substantially different value of H, especially when S is H When the rotation of the actuator 12 is "connected to the position" (see Fig. 7), the overall appearance of the actuator 12 is visually conspicuous in a substantially trapezoidal shape in a plan view. Actuate the benefit 12 to the state of "connected position". 100127696 21 201236281 Further, as shown in the present embodiment, when the inclined surfaces constituting the inclined surface portions 12b1 are smoothly connected from the flat surface portion 12b2, when the operation force is applied to the actuator 12, the two flat surfaces are applied to the flat surfaces. Since i2bi and the boundary portion of each other do not have a corner portion where stress is concentrated, damage due to the rotation operation of the actuator U can be prevented. Further, as shown in the present embodiment, when the operation avoiding portion 12b1 is provided via the both end side standing wall surface portions 12b3, the switch operation portion of the actuator 12 is increased to the extent that the both end side rising wall surface portions 12b3 are added. The rigidity of the crucible can prevent damage or the like when the operating force is applied to the actuator 12. On the other hand, in the second embodiment of Figs. 18 to 20, which is the same as the above-described constituent elements, the operation avoidance assisting unit including the other inclined surface is provided in addition to the inclined surface portion 12b1. ΐ2Μ, 12b4 are attached to both end side portions in the longitudinal direction of the connector of the actuator 12. The two operation avoidance assisting portions 12b4 and (3) the bucket actuation (10) stand at the "connection release position" (see the upper end portion of Fig. 2 and the two sides near the longitudinal direction). The position of the operation avoidance assist 12b4 is arranged. When the actuator is pushed in the direction of clamping from the state in which the signal transmission medium (FPC or FFC, etc.) F is opened, the operation force is applied to the actuator 12. Each of the operation avoiding assisting portions 12b4 is formed by another mussel inclined surface disposed along the inclined surface mi, and the inclined surface constituting the operation avoiding assisting portion is disposed along the front side of the inclined surface portion 12A. 100127696 22 201236281 More specifically, the end edge of the inclined surface of the operation avoiding assisting portion 12b4 is disposed adjacent to the end edge of the end side of the inclined surface on which the inclined surface (12) 12b is formed, and the operation avoidance portion The end edge (common edge) extends to a radial direction of the front side rising wall face Η" extending in the direction of the radius of rotation of the actuator 12 and extending substantially in a plane along the longitudinal direction of the actuator At this time, the inclination angle at which the operation avoiding assisting portion ι2 is extended is set to an appropriate angle on the lower side with respect to the rotational radius direction of the (four) 12. Further, the front side upright wall surface portion 12b5 is formed to form an actuator. 12 is extended in the "connection release position" (refer to FIG. 2A), and the front end surface (the left end surface of the figure) extends, and the front edge of the front side rises the wall surface ΐ2Μ and the inclined surface of the operation avoidance assisting portion 12b4. The other end edge is disposed adjacent to the end edge of the same side. Thus, the operation avoidance assisting system map and the inclined surface forming the inclined surface portion 12b1 are inclined downward toward the longitudinal direction of the connector, and In addition to the inclined surface portion of the first embodiment, the long side of the operation avoidance assisting unit 2 is included in the first embodiment of the operation avoidance assisting unit 2 that extends obliquely toward the front side (4) The front part of the side is more difficult to act. As a result, the operation added by the operator at the time of the actuator (4) tends to be more uniform over the entire length, from The clamping action of the transfer medium (FTC, FFC, etc.) F by the actuator 12 can be excellently performed. 100127696 23 201236281 Further, in the central portion of the longitudinal direction of the actuator 12 in the present embodiment The first and second operation support units i2b6 and 12b7 including the concave portions are provided, and the first and second operation support portions 12b6 and 12b7 are provided so as to extend in the longitudinal direction and before and after the actuator 12. The wall surface, that is, the front side upright wall surface portion 12b5' and the back side side wall surface portion on the opposite side thereof, wherein the concave portion constituting the first operation support portion 12b6 is erected on the front side upright wall surface portion 12b5, that is, actuated The front end surface (the left end surface of FIG. 20) of the state in which the device 12 is erected in the "connection release position" (see FIG. 20) is formed by an elongated groove extending substantially linearly along the longitudinal direction of the connector. Further, when the actuator 12 is rotated from the state of the open signal transmission medium (such as the FPC or the FFC), the shape of the tip end portion of the operator of the actuator 12 can be engaged. On the other hand, the second operation support unit 12b7 is the lower end surface of the rear side of the actuator 12, that is, the lower end surface of the actuator 12 lying in the "connection action position" (see FIG. 11) (FIG. 11). The lower end surface is formed by a depressed portion that extends substantially linearly along the longitudinal direction of the connector. The bending line of the outer shape line forming the second operation support portion 12b7 is formed such that the central portion in the longitudinal direction is diffused in a substantially arc shape toward the inner side in the rotational radius direction of the actuator 丨2, and is formed to be When the actuator 12 is operated from the state in which the signal transmission medium (Fpc or FFC or the like) F is held in the open direction, the shape of the nail portion of the operator of the actuator 12 can be engaged. According to the present embodiment including the first and second operation support units 12b6 and (4) 100127696 24 201236281 having such a configuration, when the actuator 12 is rotated, the operator's finger tip or finger of the actuator 12 is used. The first and second operation support portions 12b6 and 12b7 are easily applied to the central portion in the longitudinal direction. In other words, the operator's fingertip portion is easily and surely engaged with the linear first operation support portion 12b6. The operator's nail portion easily and surely engages the curved second operation support portion 12b7. . Therefore, the linear or curved operation support portions 12b7 and 12b6 are appropriately disposed on the front and rear rising wall surfaces in accordance with the rotational operation of the actuator 12, thereby obtaining good rotational operability and by the operation. The operation pressure added by the person is actively received by the central portion of the actuator 12, so that uniform operability is surely obtained over the entire length. Further, the first and second operation support portions 12b6 and 12b7 in the present embodiment are each formed of a concave portion. However, the same action and effect can be obtained by the convex portion. The present invention has been described in detail with reference to the embodiments of the present invention.
