The present invention relates to a connector for holding a cable (flexible printed circuit board (FPC) or flexible flat cable (FFC)).

As a connector having FPC or FFC, there is one described in Japanese Patent Laid-Open No. 9-92411. In this connector, an elastic force of the spring portion is used by inserting an FPC or FFC between the support portion of the contact held in the connector body and the spring portion, and then sliding or rotating the actuator made of an insulator. The press and clamp of the FPC or FFC with the operator and the support to obtain contact pressure to the FPC or FFC.

However, in the above-mentioned connector, the bottom wall of the connector body, the support of the contact, the operator, the FPC or the FFC, the contact in the height direction (the direction perpendicular to the support) of the connector in the portion where the contact pressure is obtained by crimping the FPC or the FFC. Since the spring part and the upper wall of the connector main body were provided in order, it was difficult to comply with the request for low magnification as a connector.

On the other hand, there is a connector having two contacts extending substantially parallel to each other at an approximately center portion in the longitudinal direction and having a contact made in the shape of an engineer (Japanese Patent Laid-Open No. 2004-221067). One of the two members mentioned above is a support part of the contact of this connector, and the other member comprises a spring part and a stabilizer with the connection part as a boundary. In this connector, an FPC or FFC is inserted between the support and the spring, and the operator's cam is inserted between the support and the stabilizer to engage the cam with the stabilizer, and the operator rotates about the cam to rotate the stabilizer. By lifting, the spring portion is displaced toward the support portion, whereby the spring portion compresses the FPC or FFC to obtain a contact pressure.

According to this configuration, the operator can be pulled out from the part where the contact pressure is obtained by crimping and holding the FPC or FFC, so that the member disposed in the height direction of the connector is formed by the bottom wall of the connector body, the support of the contact, the FPC or FFC, The spring portion of the contact and the top wall of the connector body can be reduced to five types. That is, compared with the connector of the said Unexamined-Japanese-Patent No. 9-92411, the reduction can be aimed at.

However, this configuration has a problem that the connector occupies a large area because the stabilizer must be extended along the longitudinal direction of the spring portion and the operator must be disposed. In addition, in order to reduce the operating force of the operator for improving workability, it is necessary to lengthen the stabilizer and the operator, and the occupied area of the connector is further increased.

In addition, if the operator rotates in the state in which the FPC or FFC is not inserted (hereinafter referred to as empty insertion), the spring portion may be excessively displaced, which may cause plastic deformation of the connecting portion. On the contrary, the connecting part may be thinly formed so as to flexibly follow the spring part excessively displaced. In this case, however, the connecting portion easily breaks when the spring portion is opened or closed when the FPC or FFC is inserted or removed, or after repeated opening and closing.

In addition, if the height of the support portion is lowered for low magnification, a strong stress is applied to the connecting portion when the FPC or FFC is inserted and detached, so that the joint portion of the connecting portion and the supporting portion is easily lifted and deformed. Thereby, there exists a problem that a predetermined contact pressure cannot be obtained in the middle of repeatedly inserting and unplugging FPC or FFC.

In order to solve the above problems, the connector of the present invention is provided with a connector main body which plugs and unplugs a cable, a support part and a spring part extending in the insertion direction of the cable, and a connection part connecting the support part and the spring part to each other, And a manipulator held in a rotatable manner with respect to the connector body, the manipulator being arranged to abut against the spring portion between the distal end portion of the support portion or the distal end portion of the spring portion and the connecting portion, and by rotating the manipulator, the spring portion is moved toward the support portion side. A pressing cam portion is provided, and the cable is electrically contacted with the tip of the support or the tip of the spring by rotating the operator to elastically displace the spring toward the support.

It is preferable that any one of the tip part of the said support part and the tip part of a spring part is provided with the contact part which protrudes to the lower wall side of a connector main body. On the other hand, the support part should just be provided in the position which opposes a contact part in the other of the tip part of the said support part, and the tip part of a spring part. The supporting portion may be installed at a position facing the contact portion of the connector body.

In the support portion, it is preferable that a retaining member is provided to extend toward the spring portion and has a engaging portion for engaging the cam portion.

The upper surface of the spring portion may be formed such that the portion where the cam portion abuts is on the support portion side than the upper surface on the contact portion side. In addition, the upper surface of the spring portion is preferably formed such that the portion where the cam portion abuts on the support portion side rather than the upper surface of the connecting portion side.

The cable rotates the operator until it is approximately parallel with the spring part, and electrically conducts the tip of the support part or the tip of the spring part by elastically displacing the spring part toward the support part, and the operator is substantially parallel to the spring part at the tip of the cam part. In this case, it is sufficient that a convex portion inserted and fixed between the upper wall of the connector body and the upper surface of the spring portion is formed.

The cable rotates the operator until it is approximately parallel with the spring portion, and electrically conducts the tip portion of the support portion or the tip portion of the spring portion by elastically displacing the spring portion toward the support portion, and on the upper wall of the connector body, the operator is approximately parallel with the spring portion. In the lowered state, it is preferable that a shell portion is formed to sandwich the tip of the cam portion with the upper surface of the spring portion and fix it.

The contact portion may be installed in the spring portion, the support portion may be installed in the support portion.

The connector may have a second contact formed by connecting two members extending substantially parallel to each other in the insertion direction of the cable at a substantially central portion thereof in the longitudinal direction.

When the cable is not inserted into the connector body, the operator may be displaced in a direction substantially perpendicular to the longitudinal direction of the spring portion in a rotational motion until it is approximately parallel with the spring portion.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

(1st Example) (FIGS. 1-4)

The connector 10 according to the first embodiment shown in FIGS. 1 to 4 has a connector main body (insulator) 20, an actuator 30, and a contact 50.

The connector body 20 into which the FPC, FFC, and other cables 12 are inserted may be formed of an insulating member (for example, 9T nylon, 66 nylon and 46 nylon, other nylon (PA), liquid crystal polymer (LCP), and poly). Phenylene sulfide (PPS)) is formed by injection molding. On the side walls 21 and 22 of the connector body 20, engaging arm members 25 and 26 extending in parallel in the depth direction (D direction in Fig. 2) and protruding inwardly are provided, respectively. (FIG. 2).

The manipulator 30 shown in FIG. 3 has a long plate shape having shaft portions 35 and 36 provided so as to protrude outward on both end faces 31 and 32 in the longitudinal direction thereof (in the L direction in FIG. 3 (a)). It is absent. The operator 30 is retained rotatably in the connector body 20 by engaging the shaft portions 35 and 36 with the engaging arm members 25 and 26. Moreover, the cam part 33 is formed in the end part (tip) of the axial direction (the W direction in FIG.3 (a)). If the cam part 33 can function as a cam, the cross section in the longitudinal direction can be arbitrarily determined, for example, it can be an ellipse, a rectangle, and a trapezoid. The shafts 35 and 36 may also be movable on both longitudinal cross-sections of the operator 30.

The operator 30, like the connector body 20, uses an insulating member (e.g., 9T nylon, 66 nylon and 46 nylon, other nylon (PA), liquid crystal polymer (LCP), polyphenylene sulfide (PSS)). It is comprised by injection molding.

As shown in FIG. 4, the contacts 50 press-fitted and held in the connector main body 20 extend substantially parallel to each other in the substantially horizontal direction (left and right direction in FIG. 4) (insertion direction of the cable 12). 52 and a spring portion 54 are provided. One end portion 52a in the longitudinal direction of the support portion 52 and one end portion 54a in the longitudinal direction of the spring portion 54 facing the end portion 52a are connected to each other by the connecting portion 55. As a result, the contact 50 becomes substantially c-shaped. The other end part (tip part) 52b of the other longitudinal direction of the support part 52, and the other end part (tip part) 54b of the other longitudinal direction of the spring part 54 face each other, and the support part 52 is provided at the end 54b. The contact portion 58 protruding toward the side of the connector body 20 (to the lower wall 24 side of the connector main body 20), and the contact portion 58 is pressed on the support portion 52 when the spring portion 54 is pressed toward the support portion 52 side. The support part 56 protrudes in the part which abuts.

By forming the contact 50 in such a shape, the elasticity of the connecting portion 55 is improved, thereby preventing plastic deformation due to co-extraction and breaking by the opening and closing of the spring portion 54 when the cable 12 is inserted and removed. can do. The contact 50 is fixed by engaging the connector body 20 with the engaging part 52d which protrudes from the upper surface 52c of the support part 52. As shown in FIG. Moreover, the tail part 59 is extended from the support part 52, and this tail part 59 is the lower wall 24 of the connector main body 20 when the contact 50 is pressed in the connector main body 20. Moreover, as shown in FIG. It extends from and solders to the circuit board.

As for the contact portion 58 and the support portion 56 of the contact 50, the contact portion 58 is provided at the end portion 52b of the support portion 52, and the support portion 58 is formed at the end portion 54b of the spring portion 54. 56) may be formed. That is, it is also possible to obtain conduction by making the contact surface of the cable 12 face the support part 52 side. In addition, the connection part 55 may be formed in the contact part 56 side rather than the edge part 52a of the support part 52, and / or in the contact part 58 side rather than the edge part 54a of the spring part 54. As shown in FIG. That is, the shape of the contact 50 is not limited to the c-shape mentioned above, For example, it can be made into a wedge shape or an industrial shape. In addition, when the connecting portion 55 is a plate shape or a rod shape perpendicular to the support portion 52 and the spring portion 54, the contact 50 becomes a substantially U-shape as described above. Instead, the connecting portion 55 is curved. The shape of the contact 50 may be made substantially U-shaped.

The contact part 60 which the cam part 33 of the operator 30 contacts is formed in the substantially center of the spring part 54 in the longitudinal direction, when the operator 30 is rotated and the contact 50 is closed. The upper surface 60a (the surface farther from the supporting portion 52) of the contact portion 60 is the upper surface 54e on the contact portion 58 side of the spring portion 54 and the upper surface (side on the connection portion 55 side). It is provided concave toward the support part 52 rather than 54f). From this contact part 60, the curved part 54g which gradually separates from the support part 52 as it goes to the contact part 58 side extends, and the spring part 54 in the contact 50 of an open state is extended. It extends substantially parallel with the support part 52 in the edge part 54b from this bend part 54g. That is, the upper surface 60a of the contact portion 60 is larger than the upper surface of the portions other than the contact portion 60 (the upper surface of the contact portion 58 side of the spring portion 54 and the upper surface of the connection portion 55 side). It is in the support part 52 side. By having the spring part 54 in such a structure, the operator 30 which contacts the contact part 60 can be arrange | positioned in the low position (position of the support part 52 side), and the low magnification of the connector 10 is made. We can plan. In addition, by making the upper surface 54f of the coupling portion 55 side portion of the spring portion 54 higher than the upper surface 60a of the abutting portion 60, the connecting portion 55 can be made large, so that the stress can be dispersed. Therefore, plastic deformation and fracture can be prevented. In addition, this contact part 60 can be provided in any position of the spring part 54 except the upper part of the contact part 58 or the connection part 55. As shown in FIG. Moreover, if the upper surface 60a of the contact part 60 is in the support part 52 side rather than either of the upper surface 54e of the contact part 58 side, and the upper surface 54f of the connection part 55 side, And height may be the same.

The contact 50 is, for example, phosphor bronze (Cu-Sn-based copper alloy), beryllium copper (Cu-Be-based copper alloy), titanium copper (Cu-Ti-based copper alloy), Corson-based copper alloy (Cu-Ni -Si-based copper alloys) and other copper alloys by stamping molding with a forward die, and the surface is plated with, for example, gold, copper-tin, or tin-lead. do. On the other hand, the contact part 60 may be formed by bending after shaping | molding.

The operator 30 is disposed so that the cam portion 33 abuts the upper surface 60a of the contact portion 60 of the spring portion 54. When the operator 30 engaged with the connector main body 20 is rotated, the spring portion 54 elastically displaces in accordance with the shape of the cam portion 33 abutting against the abutting portion 60. That is, in the state where the operator 30 is substantially perpendicular to the spring part 54 of the contact 50, the contact 50 will be in an open state (FIG. 4 (a)), and the operator 30 will be opened from the open state. When the rotary motion is moved to a state substantially parallel to the spring portion 54 of the contact 50, the contact 50 is in a closed state (Fig. 4 (b)). In this closed state, the distance between the upper surface of the upper wall 23 of the connector body 20 and the tip of the cam portion 33 becomes H1.

The cable 12 is inserted into the contact 50 in the open state in a direction substantially parallel to the support 52, and the positioning portion 27 formed between the contacts 50 arranged in parallel with each other in the connector body 20. Position is brought into contact with the tip, and it is inserted and fixed by rotating the operator 30 to bring the contact 50 into the closed state (Fig. 4 (c)). Here, since the bent portion 54g of the spring portion 54 is disposed on the connecting portion 55 side than the positioning portion 27 in the insertion direction of the cable 12, the spring is formed at a portion other than the contact portion 58. The contact of the part 54 and the cable 12 can be avoided. In this way, by closing the contact 50, the cable 12 can be crimped by the contact pressure of the contact portion 58 and the support portion 56 to obtain electrical conduction (electrical contact). In the closed state (c) of FIG. 4 when the cable 12 is inserted, the distance between the upper surface of the upper wall 23 of the connector body 20 and the tip of the cam portion 33 becomes H2. This distance H2 is smaller than H1. That is, by the structure which engages the shaft parts 35 and 36 with the engaging arm members 25 and 26, and makes the operator 30 rotatable, the operator 30 displaces in the up-down direction even in the closed state at the time of insertion or removal. Since it is possible, plastic deformation of a connection part can be prevented. By setting the shape of the contact portion 60 of the spring portion 54 and the shape of the cam portion 33 in contact with the contact portion 60 to the above-described shape, opening and closing of the contact 50 is stabilized and the operator 30 ), A feeling of click when the cable 12 is crimped can be obtained. In addition, when the operator 30 is in the halfway position, the operator 30 may restore or rotate the position to any one of the open state and the closed state. The distance between the contact portion 58 and the support portion 56 can be set according to the thickness of the cable 12.

For example, if the distance between the contact portion 58 and the support portion 56 of the contact 50 in the open state is set to be approximately equal to or slightly smaller than the thickness of the cable 12, the operator 30 is operated to make the spring. The cable 12 can be temporarily retained even when the portion 54 is not pressed toward the support portion 52. In this case, a slight force (insertion force) for inserting the cable 12 into the contact 50 is generated (LIF (Low Insertion Force)), but the contact portion 58 and the support portion 56 are not impaired in workability. Set the interval of). In addition, when the distance between the contact portion 58 and the support portion 56 of the open contact 50 is larger than the thickness of the cable 12, the insertion force can be almost zero (ZIF (Zero Insertion Force)). There are various settings to suit your requirements.

The approximately U-shaped contacts 50 of the first embodiment are used in the connector main body 20 so that the longitudinal directions thereof are substantially parallel to each other, and in addition to the contact 50, the above-described Japanese Patent Application Laid-Open No. 2004-221067. The conventional substantially industrial contact (second contact) 150 (FIG. 6) described can also be arrange | positioned at the intersection (FIG. 5). The manipulator 130 used for the connector 110 in this case is a shape which engages with the stabilizer 170 in the position where the approximately engineering contact 150 is arrange | positioned among the cam parts 33 of the manipulator 30 mentioned above. The conventional cam portion 133 is formed. The approximately C-shaped contact 50 and the approximately industrial-shaped contact 150 are retained in the connector body 120.

The approximately U-shaped contacts 50 and the approximately industrial contacts 150 disposed as described above preferably have the following elastic characteristics. That is, when attempting to close the two contacts 50 and 150 by rotating the operator 130 at the time of ball insertion and detachment, the force required to push down the spring portion 54 of the approximately C-shaped contact 50 toward the support portion 52 side ( It is preferable that the force F2 required for lifting the stabilizer 170 of the F-shaped contact 150 at this time is approximately F1> F2. In this setting, since the approximately C-shaped contact 50 is more likely to be displaced than the approximately 150-shaped contact 150, when the ball is removed, the approximately C-shaped contact 50 is displaced by the operator 30. 30 is pushed down by the stabilizer 170 to the support part 52 side. That is, the spring 170 154 can be suppressed from being excessively displaced by lifting the stabilizer 170 at the time of the ball insertion and detachment, thereby preventing plastic deformation of the connecting portion 155.

In addition, in the connector 110 of such a structure, when the cable 12 is inserted, the force acting in the direction away from the support part 52 with respect to the cam part 33 which abuts on the substantially C-shaped contact 50 increases. . As a result, the force acting in the direction away from the supporting portion 152 with respect to the stabilizer 170 of the approximately worker-shaped contact 150 is also increased. However, since the cable 12 is inserted into the substantially U-shaped contact 50, the amount of displacement is regulated, whereby the operator 30 is positioned at a point away from the support 52 side as compared with the time of empty insertion. Thus, although the stabilizer 170 is lifted up, the spring portion 154 can retain the elasticity of the connecting portion 155 without excessive displacement. By using together with the contact 50 of 1st Embodiment as mentioned above, the spring part 154 does not displace excessively at the time of insertion or detachment and the insertion of the cable 12, and solves the problem of the conventional industrial contact 150. Can be.

(2nd Example) (FIG. 7, FIG. 8)

Next, a second embodiment of the present invention will be described. The connector 210 of the second embodiment shown in FIG. 7 includes a retaining member 280 in the support portion 252 of the contact 250 (FIG. 8), and an engaging hole portion of the cam portion 233 of the operator 230. The first embodiment differs from the first embodiment in that the shape 233a is engaged with the engaging portion 281 provided at the distal end of the holding member 280. The rest of the configuration is the same as in the first embodiment, and the same reference numerals are used for the same members.

In the contact 250 of the connector 210 according to the second embodiment, the engaging hole 233a provided at the distal end of the cam portion 233 at the distal end so as to extend from the support portion 252 toward the spring portion 54. A retaining member 280 having an engaging portion 281 that is engaged is provided. The retaining member 280 is integrally formed by the same material as the supporting portion 252 and the spring portion 54 by stamping molding together with the supporting portion 252 and the spring portion 54. In addition, this holding member 280 may be formed by bending the support part 252 previously formed. In addition, it is preferable to provide the retaining member 280 in the connector body 20 by providing an engaging portion (not shown) in the retaining member 280 and pressing the engaging portion into the connector main body 20. In addition, the contact 250 according to the first embodiment and the contact 250 according to the second embodiment may be used in parallel.

The engaging portion 281 of the retaining member 280 has a substantially c-shaped cross-sectional shape engaged with the engaging hole portion 233a. At the distal end of the engaging portion 281, a hook portion 281a protruding toward the support portion 252 side is provided. An end portion 233a1 is formed on the side surface of the engagement hole 233a which is engaged with the engagement portion 281. Thus, the retaining member 280 and the cam portion 233 are engaged with each other by engaging the end portion 233a with the hook portion 281a inserted into the engaging hole portion 233a. In this manner, the operator 230 is retained as the contact 250. Thereby, even when the connector 210 is made multi-pole, the operator 230 can be prevented from floating or loosening, and the operator 230 can be stably rotated. In addition, since the holding member 280 is formed integrally with the support part 252 and the spring part 54 by the metal material, it can be formed with high precision. As a result, the strength of the contact 250 is improved, and the stability of the rotational movement of the operator 230 can be further improved.

In addition, the other effect | action, an effect, and a modification are the same as that of 1st Example.

(Third Embodiment) (Fig. 9)

Next, a third embodiment of the present invention will be described. In the connector 310 of the third embodiment shown in FIG. 9, the convex portion 333a extending in the width direction of the operator 330 is provided at the tip of the cam portion 333, which is different from the first embodiment. The rest of the configuration is the same as in the first embodiment, and the same reference numerals are used for the same members.

In the first embodiment, in the state where the operator 330 is rotated so as to close the contact and is substantially parallel to the spring portion, there is no upper wall of the connector body above the cam portion 333. In contrast, the operator 330 of the third embodiment is provided with a convex portion 333a extending further in the longitudinal direction of the operator 330 at the tip of the cam portion 333. The convex portion 333a is integrally formed as the operator 330 so as to become narrower toward the tip of the operator 330. According to this structure, when the contact 50 is closed by rotating the operator 330, the convex part 333a contacts the upper wall 23 of the connector main body 20, and the upper surface 60a of the contact part 60 is carried out. (Or the upper surface 54e of the spring portion 54), the operator 330 can be suppressed from rising. On the other hand, even when the shaft parts 35 and 36 of the operator 330 are disposed close to the upper wall 23 of the connector main body 20 without providing the convex part 333a, the tip end of the cam part 333 is also arranged. Since it can be sandwiched between the upper wall 23 of 20 and the upper surface 60a of the contact part 60, it can suppress that the operator 330 rises by this.

In addition, the other effect | action, an effect, and a modification are the same as that of 1st Example.

(4th Example) (FIG. 10, FIG. 11)

Next, a fourth embodiment of the present invention will be described. The connector 410 of the fourth embodiment uses the operator 330 of the third embodiment. When the operator 330 is approximately parallel with the spring portion 54 to close the contact 50, the connector 410 of the cam portion 333 The first embodiment differs from the first embodiment in that the shell 428 extending from the upper wall 423 of the connector main body 420 in parallel with the longitudinal direction of the indicator 52 is provided so as to cover the convex portion 333a. This shell portion 428 is fixed by engaging projections 428a and 428b protruding outward from the longitudinal ends thereof to the connector body 420. The operator 330 extends the shaft portions 335 and 336 respectively installed so as to protrude outward from the faces of the longitudinal ends 331 and 332, respectively, in the depth direction of the connector body 420 from the side wall (not shown) to the connector body 420. Thus, the tip is engaged with the engagement arm members 425 and 425 having a shape projecting inwardly, so that the tip is held in a rotatable manner. The rest of the configuration is the same as in the first embodiment, and the same reference numerals are used for the same members.

The shell portion 428 is made of, for example, the same material as the above-described contact 50 or stainless steel (SUS), and is formed by stamping molding using a net transfer mold. The connector body 420 is assembled by press fitting or insert molding.

In addition, when an auxiliary tool is required in order to improve the peeling strength with respect to a mounting board | substrate, you may form integrally with the shell part 428 and mount it on a board | substrate. In this case, it is common to arrange the tail portions 429 extending from the lower wall 424 of the connector body 420 at both ends in the longitudinal direction of the connector body 420. With this configuration, the connector body 420 is a shell portion. Since it is surrounded by 428, it is advantageous for peel strength and electromagnetic interference (EMI).

According to this configuration, when the contact 50 is closed by rotating the operator 330, the convex portion 333a of the cam portion 333 is in contact with the shell portion 428 and the upper surface 60a of the contact portion 60. Since it enters in between, the operator 330 can be suppressed from rising. In addition, when the metal shell 428 is grounded, EMI can be prevented and the high frequency characteristic of the connector 410 can be improved.

(5th Example) (FIG. 12)

In the connector 510 of the fifth embodiment shown in FIG. 12, the contact 550 is used instead of the contact 50, and the lower wall 524 is thicker than the lower wall 24 toward the upper wall 523 instead of the connector body 20. The use of one connector body 520 is different from the first embodiment. The rest of the configuration is the same as in the first embodiment, and the same reference numerals are used for the same members.

The contact 550 has a support portion 552 and a spring portion 554 extending substantially parallel to each other in a substantially horizontal direction (left and right direction of Figure 12). One longitudinal end 552a of the support 552 and one end 554a in the longitudinal direction of the spring part 554 facing the end 552a are connected to each other by a connecting part 555. The other end part (tip part) 554b of the spring part 554 in the longitudinal direction is provided with the contact part 558 which protrudes toward the lower wall 524 side of the connector main body 520. As shown in FIG. The contact part 560 which the cam part 33 of the operator 30 abuts is formed in the substantially center of the spring part 554 in the longitudinal direction of the spring part 554 when the operator 30 rotates and the contact 550 is closed. The upper surface 560a (surface farther from the supporting portion 552) of the contact portion 560 is the upper surface of the contact portion 558 side of the spring portion 554 similarly to the spring portion 54 of the first embodiment. It is recessed in the support part 552 side rather than the upper surface 554f by the side of 554e and the connection part 555.

On the other hand, the end portion 552b of the support portion 552 extends only to the position facing the contact portion 560, unlike the end portion 52b of the support portion 52 in the first embodiment. That is, the end 552b and the end 554b do not face each other. The contact 550 is fixed by engaging the engaging portion 552d protruding from the tip of the end 552b to the engaging recess 529 of the connector body 520. In addition, the tail portion 559 is formed to extend from the support portion 552, and the tail portion 559 is the lower wall 524 of the connector body 520 when the contact 550 is pressed against the connector body 520. It extends from and solders to the circuit board.

In the connector 510 of the fifth embodiment, the cable is inserted into the contact 550 in the open state (FIG. 12 (a)) in a direction substantially parallel to the support 552, and rotates the operator 30 to make the contact ( 550) in the closed state (FIG. 12 (b)) to fix it. In this way, by closing the contact 550, the electric pressure (electrical contact) can be obtained by pressing the cable at the contact pressure between the contact portion 558 and the lower wall 524. In the first embodiment, the support portion 56 extends the support portion 52 to a position facing the contact portion 58. However, by shortening the support portion 552, the contact 550 is formed in the connector body 520. It is stable and the connector main body 520 is hold | maintained more reliably, and the assembly property of the connector 510 is improved.

Although this invention was demonstrated with reference to the said Example, this invention is not limited to the said Example, It is possible to improve or change within the objective of improvement or the thought of this invention.

According to the present invention, since a stabilizer is not required, the number of components in the part where the contact pressure is obtained by crimping the FPC or the FFC can be reduced, thereby realizing low magnification and reducing the area occupied by the connector. You can do it. Further, the length of the spring portion can sufficiently have the cable insertion direction. That is, the length of the spring portion can be equal to the length of the connector depth direction. Moreover, since the amount of contact displacement by the operator for obtaining a predetermined contact pressure is small, the stress generated at the connection part during insertion and removal and when the FPC or FFC is inserted and removed can be prevented, thereby preventing deformation or breakage of the connection part. As a result, a stable contact pressure can be obtained. Further, even if the operator is long to reduce the operating force, the influence on the area occupied by the connector is small, so that miniaturization and improved operability can be realized simultaneously.
