Description

Connector {connector}

The present invention relates to a connector for connecting a connecting object on a thin plate such as FPC or FFC.

Fig. 14 is a conventional example of a connector of a type in which a connecting object (FPC, FFC, etc.) on a thin plate can be connected and the connector connects to the connecting object when the actuator is laid on the side opposite to the escape direction of the connecting object. Japanese Patent Laid-Open No. 11-31561).

This connector is provided with an insulator which can insert and remove a connection object, and an actuator which is a plate-shaped resin member rotatably supported by the insulator. The contact has a fixed piece parallel to the direction of insertion of the connection object and a movable piece capable of swinging with respect to the fixed piece around the intermediate portion, and between the fixed piece and one end of the movable piece (left end in Fig. 14). Can be inserted and removed. On the other end side (right end part in FIG. 14) of a movable piece and a fixed piece, the engaging protrusion and the fall prevention protrusion are respectively protruded. Moreover, the cam part located between the stationary piece and the other end of the movable piece is formed in the end part of an actuator, and the some through-hole is formed in parallel with the contact part in the vicinity of the cam part of an actuator.

As shown in Fig. 14A, when the actuator is located at an unlocked position perpendicular to the longitudinal direction of the insulator, the other end of the movable piece of each contact penetrates the corresponding through hole of the actuator, respectively, The cam portions are separated from each other in the movable piece.

On the other hand, as shown in Fig. 14 (b), when the actuator is inserted between the stationary piece and one end of the movable piece, the actuator is rotated to a lock position in which the actuator is turned over to the side opposite to the escape direction of the connection object. Since the cam portion presses the other end of the movable piece in a direction away from the stationary piece, one end of the movable piece approaches the stationary piece and contacts the connection object. In addition, since the engaging projection of the movable piece and the release preventing projection of the fixed piece are fitted into the through hole to engage with the cam portion, respectively, the cam portion is prevented from escaping in the right direction of FIG. 14 between the fixed piece and the movable piece.

Since low magnification (less than 1 mm) and high density have been strongly demanded for this type of connector in recent years, the actuator used as a component must be thinned. In order to cope with such thinning, the cam portion that transmits the operating force to the movable piece made of resin should also be thinner (Fig. 14 (a) up and down direction) and lower (Fig. 14 (b) up and down direction).

However, even when the cam portion is downsized, it is necessary to prevent the camp from falling in the locked position, the unlocked position, and the rotating operation position. Therefore, conventionally, through-holes through which movable pieces are penetrated to the actuator are formed so that the engagement projections and the release prevention projections are formed at the same position with respect to the insertion direction of the contact object, and the distance between the engagement projections and the release prevention projections is narrower than that of the cam portion. This prevents the actuator (cam part) from dropping in the direction of insertion and withdrawal.

On one side, the actuator is in the angular position of the unlocking position, and the cam part is brought into contact with the contact by inserting the cam part between the anti-logging protrusion and the engaging protrusion and riding over the engaging protrusion, so that the anti-logging protrusion has a tapered narrow width (degrees). 14 left and right dimensions are small) shape. However, when the operator accidentally pushes the actuator positioned at the release position toward the exit direction of the connection object in the production process, etc., when the actuator is accidentally locked, the cam portion is rotated from the center. There is a risk of the actuator falling out from the other end of the stationary piece and the movable piece (right direction in Fig. 14).

An object of the present invention is to provide a connector which can prevent the actuator from falling off from the insulator when the actuator located in the release position perpendicular to the direction of insertion and withdrawal of the connection object is pressed even in a thin shape. It is to offer.

The connector of the present invention includes an insulator in which a thin plate-like connection object can be inserted and escaped, a first fixing piece parallel to the insertion direction of the connection object fixed to the insulator, and a first movable piece that can swing relative to the first fixing piece about an intermediate portion. Between the first contact between which the connection object is inserted and the locking position lying on the opposite side to the escape direction and the release position orthogonal to the insertion direction between the first fixing piece and one end of the first movable piece; It is rotatable with respect to the insulator and is located between the first movable piece and the other end of the first fastening piece, and when moving to the locked position, the other end of the first movable piece is pushed in a direction away from the first fastening piece to the first In a connector having an actuator having a cam portion for bringing one end of the movable piece into contact with the connecting object. And a release preventing protrusion having a hook portion protruding from the cam portion by being positioned from the cam portion to the other end side and protruding toward the one end side, and preventing the falling off at the other end of the first movable piece. An engaging projection which protrudes from the projection to the one end side and engages with the cam portion of the actuator located at the lock position from the release preventing projection side, formed in the actuator, and the actuator being in the unlocked position A recess for the other end of the first movable piece to be fitted to the opposite side of the actuator, and when the actuator is in the unlocked position, Characterized by having a rotational regulating surface engaged with it. And there.

The actuator may be provided with a dividing wall for partitioning the release recess and the rotation restricting surface in an airtight state.

The side of the side which provided the said recessed part of the said actuator provided with the 2nd contact which the said connection object is inserted between the 2nd fixed piece parallel to the insertion direction of the said connection object fixed to the said insulator, and one end of a 2nd movable piece. A contact surface may be formed on the surface when the actuator is positioned at the release position so that the other end of the second movable piece abuts.

On the flat surface formed on the surface on the opposite side to the said recessed recessed part of the said actuator, and when it is located in the said locking position, it is formed in the flat surface formed in the part located in the said one end part from the said release prevention protrusion of the said 1st fixing piece or insulator. It may be provided with the flat locking oil surface in surface contact.

When it is located in the locking position on the side opposite to the pullout recess of the actuator, the pullout prevention projection may be fitted to form a pullout prevention recess that is independent of the pullout recess and the cam portion.

When the actuator is positioned at the release position, the actuator may be provided with a flat release surface which is in surface contact with a flat surface formed at a portion located at the one end portion from the release preventing projection of the first fixing piece or the insulator.

According to the present invention, by positioning the engaging projection of the movable piece to one end side from the fall prevention projection of the fixing piece, the space (distance) in the length direction of the contact between the engaging projection and the fall prevention projection in the direction of insertion and withdrawal of the contact object. And a recessed recess for engaging the engaging projection of the movable piece when it is positioned in the unlocked position on the actuator, and a rotation restricting surface for engaging the release preventing projection of the fixed piece. Therefore, even when the connector is thin, it is possible to make both the rotational movement to the release position of the actuator and preventing the actuator from falling off during misoperation by fitting the other end of the movable piece to the recessed recess.

Dropping of the actuator is specifically prevented by the following method. That is, when the actuator is positioned in the unlocked position, the rotation restricting surface formed on the actuator is engaged from the first fixing piece side with respect to the hook portion of the release preventing protrusion provided to protrude to the first contact (first fixing piece). Therefore, even if the operator accidentally presses the actuator positioned at the release position toward the exiting direction of the connection object, the rotation of the actuator is prevented by the hook portion and the rotation restricting surface, so that the cam portion of the first fixing piece and the first movable piece (the End) and prevent dropping from the actuator contacts and insulators.

According to the structure of claim 2, the rigidity of the entire actuator is improved because the strength of the cam portion is improved and the cavities (the part formed with the release recess and the rotation restricting surface) do not become hollow holes, thereby improving the rotational behavior of the actuator. ) Is stable. Moreover, since it does not become a hollow hole, flow resistance is also reduced from the viewpoint of the fluidity of the resin at the time of injection molding, which is preferable.

According to the configuration as claimed in claim 3, since the actuator is restricted in the insertion direction so that the actuator cannot move in the escape direction of the connection object by contacting the other end of the second movable piece with the contact surface when released, the rotation restricting surface of the actuator The hook portion of the overhang prevention protrusion can be more securely engaged, and the fall of the actuator during misoperation can be prevented more.

According to the structure as described in Claim 4, since the locking recess surface does not exist in the lock holding surface side in an actuator, a lock holding surface can be formed large. As a result, the actuator can be easily held in the locked position by the locking holding surface, so that a change in contact pressure between the contact (moving surface) and the connecting object can be prevented.

According to the structure as described in Claim 5, since the fall prevention recess is formed independently from the fall prevention recess to which the fall prevention protrusion fits, it is independent and it can improve the intensity | strength of the vicinity of a fall prevention recess. Therefore, the actuator is prevented from being inadvertently pulled out by the normal operation or by the excessive operation of the actuator because the actuator is prevented from falling out by the engagement of the release preventing protrusion and the release preventing recess when the actuator is locked. none.

In addition, since the displacement of the movable piece is regulated because the relative movement in the direction of insertion and escape of the connection object to the contact (and the insulator) of the actuator is regulated, it is necessary to suppress the change in contact pressure or contact resistance due to the theory of the actuator. It becomes possible.

In addition, there is no fear that the cam portion is shaved by the release preventing projection because the release preventing projection is not stuck to the cam portion.

In addition, the fall prevention recesses to which the other end (mating protrusion) of the movable piece does not fit when the actuator moves to the locked position do not need to be widened in accordance with the detachment recesses because they are recesses independent of the ejection recesses.

As in the invention described in claim 6, when the releasing holding surface is formed on the actuator, the actuator is easily held in the releasing position when the actuator moves to the releasing position.

The rotary actuator 70, which is a plate member extending in the left and right directions, is an injection molding of a heat-resistant synthetic resin material using a metal mold. Rotating support shafts 71 extending toward left and right sides and coaxial with each other are provided at the lower ends of the left and right sides. In the vicinity of the lower end of the surface of the actuator 70 (the front surface in FIG. 1 and the top surface in FIG. 2), a total of 35 evacuation recesses 72 are provided in a concave side-by-side direction, and the left and right sides of the actuator 70 are provided. On the lower end except for both side portions, a cam portion 73 extending in the left and right directions is formed, and at the end thereof, a bent projection portion 73a is provided to protrude. In addition, a total of 17 anti-falling recesses 74 located at the same left and right positions as the first contacts 40 are recessed on the back surface of the actuator 70 (the back surface of FIG. 1 and the bottom surface of FIG. 2). It is installed. Moreover, the cross section (lower end surface) of the lower end part of each support recessed part 74 with a smaller recessed quantity compared with the upper part comprises the rotation control surface 74a. As shown, the separation recess 72 and the prevention prevention recess 74 (rotation control surface 74a) are separated by a dividing wall 70a in an airtight state. In addition, the whole lower end part (part except the rotation support shaft 71) of the back surface side of the actuator 70 consists of the flat locking surface 75 extended in the left-right direction, and the whole lower end surface of the actuator 70 is loosened flat. The holding surface 76 is formed.

The actuator 70 places its lower end (except for the rotation support shaft 71) in the actuator receiving recess 22 of the insulator 20 and the left and right rotation support shafts 71 for the left and right bearings. It is rotatably fitted around the rotation support shaft 71 with respect to the insulator 20 by rotatably fitting to the part 23 (refer FIG. 6).

The actuator 70 rotates between an orthogonal release position (positions shown in FIGS. 1, 6-8) and a horizontal locking position (positions shown in FIGS. 2, 12, and 13) with respect to the insulator 20. can do.

As shown, when the actuator 70 is in the unlocked position, the engagement protrusion 50 of the first contact 40 and the engagement protrusion 68 of the second contact 60 are connected to the actuator 70. It is inserted in the corresponding recessed recess 72 so that it can flow (the rear end of the movable piece 62 contacts the contact surface 72a at the time of release formed on the inner surface of the recessed recess 72), and each The curved protrusion 73a is engaged with the lower ends of the engaging protrusions 50 and 68. In addition, the rotation restricting surface 74a abuts on the lower surface of the hook portion 46a of the anti-separation protrusion 46 of the first contact 40 from below.

On the other hand, when the actuator 70 is located in the locked position, each of the bent portions 73a of the cam portion 73 of the actuator 70 is connected to the engaging projection 50 and the second contact 60 of the first contact 40. While engaging the engaging projection 68, pressing the rear ends of the movable piece 42 and the movable piece 62 upwards, while the movable piece 42 and the movable piece 62 elastically deform the deformable connecting portions 43 and 63. Because of swinging, the front end portions of the movable piece 42 and the movable piece 62 approach the stationary pieces 41 and 61 side. In addition, the fall prevention projections 46 of the first contacts 40 are fitted to the fall prevention recesses 74.

To mount the connector 10 having the above configuration to the upper surface of the circuit board CB (refer to FIGS. 1 and 2), the suction unit (not shown) of the insulator 20 is formed by a suction means (not shown) located above the connector 10. The upper surface of which the mold release hole 33 is not formed is adsorbed and the hooking means 47 of each of the first contacts 40 and the hooking portions of the second contact 60 are moved by moving the suction means. 64 is placed on a circuit pattern (not shown) coated with a predetermined amount of solder paste on the circuit board CB. Then, the solder paste is heated and melted in the reflow furnace, and the respective hook-shaped locking portions 47 and 64 are soldered to the circuit pattern.

It is a sheet-shaped long object that is elastically deformable to the flexible printed circuit (FPC) 80 as a connection object, and its thickness is a distance between the contact protrusion 44 and the contact protrusion 49 of the first contact 40 in the free state. And the distance between the contact protrusion 65 and the contact protrusion 67 of the second contact 60 in the free state. The FPC 80 is a laminated structure formed by adhering a plurality of thin film materials to each other, and a total of 18 circuit patterns 81 extending linearly along the extending direction of the FPC 80 and adjacent circuit patterns 81. Insulation which is located between and covers both surfaces of a total of 17 circuit patterns 82 in which both ends thereof retreat from the ends of the circuit patterns 81 and portions except both ends of the circuit patterns 81 and the circuit patterns 82. The cover layer 83 and one surface (upper surface in the figure) provided at both ends in the longitudinal direction are integrated with both ends of the circuit patterns 81 and 82, and have a hard end reinforcing member 84 as compared with the other parts. have.

When the actuator 70 of the connector 10 integrated with the circuit board CB is positioned in the unlocked position shown in FIGS. 1 and 6 to 8, the rear end of the insulator 20 is on the same plane (horizontal plane). The loosening oil surface 76 is brought into surface contact with a total of 19 horizontal flat surfaces 28 (the bottom of the actuator receiving recess 22 and the bottom of the left and right bearing recesses 23) formed so as to be positioned. The actuator 70 is held in the unlocked position because the rotation restricting surface 74a abuts downwardly from the lower surface of the hook portion 46a of each fall prevention projection 46. In addition, since the rear end of the movable piece 62 restrains the forward movement of the actuator 70 by contacting the inner surface (the contact surface 72a at the time of release) of the recessed concave portion 72 for release, the unlocking of the actuator 70 is performed. Holding in position can be made more certain.

In this state, when the FPC 80 is inserted into the FPC insertion groove 21 from the front of the insulator 20, the FPC 80 may come into contact with the contact surface 21a whose rear end surface is the rear end surface of the FPC insertion groove 21. It moves backward until it enters between the contact projections 44 and the contact projections 49 of each first contact 40 and between the contact projections 65 and the contact projections 67 of each second contact 60.

When the actuator 70 is rotated backward in this state, the actuator 70 rotates to the locked position shown in Figs. 2, 12 and 13 after the position shown in Figs. At this time, a feeling of click can be obtained by contacting each of the flat surfaces 28 with the protruding lines 77 formed between the loosening holding surface 76 and the locking holding surface 75 and extending in the horizontal direction. When the actuator 70 rotates from the unlocked position to the locked position, the front and rear positions of the left and right rotation support shafts 71 move back and forth with respect to the bearing recesses 23. When the actuator 70 moves to the locked position, the engagement protrusion 50 of the first contact 40 and the engagement protrusion 68 of the second contact 60 are rearward of the cam portion 73 of the actuator 70. (The engaging projections 50, 68 are fitted into the recessed recesses 72), and the anti-separation protrusions 46 of the respective first contacts 40 are fitted into the respective recessed recesses 74. Is fitted, and the actuator 70 is held in the locked position because the lock retaining surface 75 is in surface contact with each of the flat surfaces 28. Then, as the actuator 70 rotates to the locked position, the contact protrusions 65 of the movable pieces 42 contact each circuit pattern of the FPC 80 while the contact protrusions 44 are in contact with the bottom surface of the FPC 80. The contact projections 67 of the movable pieces 62 are in contact with the contact portion 82a formed at the end of the 82 and the contact projections 65 are in contact with the lower surface of the FPC 80. Since it contacts the contact portion 81a formed at the end of the circuit pattern 81, the circuit board CB and the FPC 80 are electrically connected to each other through the first contact 40 and the second contact 60. .

When the first contact 40 and the second contact 60 are to be released from the FPC 80, the rear end of the actuator 70 may be rotated upward. At this time, when the actuator 70 reaches the positions shown in FIGS. 10 and 11, the protruding string 77 contacts the flat surface 28 and the cam portion 73 contacts the movable pieces 42 and 62. Since the actuator 70 generates a rotation moment M (see FIGS. 10 and 11) toward the release position, the actuator 70 is reliably rotated to the release position. Therefore, incomplete manipulation of the actuator 70 can be prevented.

According to the present embodiment described above, the missing recess 72 and the missing prevention recess 74 are separately formed in the actuator 70 (a partition wall 70a is provided between the two members), and the recess is recessed. Since the part 72 and the fall prevention recess 74 do not form a through hole, even if the actuator 70 becomes thin, the mechanical strength of the actuator 70 does not significantly decrease. In addition, when the actuator 70 is molded using a metal mold, it is possible to prevent the resin material, which is used as a raw material, from becoming difficult to flow around the portion corresponding to the recessed portion for releasing the mold (to reduce the flow resistance). Because of this, the actuator 70 can be molded with high accuracy.

The connector 10 of this embodiment arrange | positions each contact 40 and 60 by 0.2 mm pitch, The plate thickness of the 2nd contact 60 is 0.08 mm and the plate of a 1st contact from a resilient design or rigidity viewpoint. The thickness is made into 0.1 mm. Therefore, in consideration of manufacturing tolerances or clearance, the width of the recessed recess 72 corresponding to the second contact 60 is 0.1 mm, and the recessed recess 72 corresponding to the first contact 40. Since the width of the s) is set to 0.12 mm, the distance between the adjacent recessing portions 72 becomes 0.09 mm. As described above, in the case of injection molding the actuator 70, which is a thin part whose cross-sectional shape with a gap of about 0.1 mm is repeatedly changed, molding becomes very difficult when the flow resistance of the resin material is large, but the flow of the resin material as in the present embodiment When the resistance is extremely reduced, the actuator 70 can be molded. In addition, it is possible to prevent the thickness of the entire partition wall 24 of the insulator 20 from being thin by modifying the plate thickness of the first contact 40 and the second contact 60.

In addition, when the actuator 70 rotates between the unlocked position and the locked position, the left and right rotation support shafts 71 move forward and backward, but the fall prevention protrusions 46 of the respective first contacts 40 are more than the engaging protrusions 50. Since the cam part 73 can be made large (thick thickness) and the lock holding surface 75 etc. can be formed, since it is located backward and formed, the freedom of design improves. The lower end of the actuator 70 rotates smoothly between the rear end of the fixed piece 41 and the rear end of the movable piece 42 (and between the rear end of the fixed piece 61 and the rear end of the movable piece 62). can do.

In addition, when the actuator 70 is in the unlocked position (especially when the FPC 80 is not inserted into the FPC insertion groove 21), even if the operator accidentally pushes the actuator 70 forward, the actuator ( 70 tries to rotate forward about the rotation support shaft 71, but this rotation is restricted by the abutment relationship between the rotation restricting surface 74a and the hook portion 46a. Therefore, the cam portion 73 exits rearward between the fall prevention protrusion 46 and the engagement protrusion 50, so that the actuator 70 is insulated from the insulator 20, the first contact 40 and the second contact 60. There is no fall off.

In addition, since there is no release recess 72 on the back surface of the actuator 70, and the distance from the release retaining surface 76 to the release preventing recess 74 is increased, the lock retaining surface 75 is provided. The area (front and back length in FIG. 12) of the becomes large. Therefore, it is easy to keep the actuator 70 in a stable position by the lock holding surface 75.

In addition, when the actuator 70 moves to the locked position, the fall preventing projection 46 of each first contact 40 is fitted to the corresponding fall preventing recess 74 of the actuator 70, thereby moving to the locked position. It is possible to reliably prevent the actuator 70 from moving relative to the first contact 40 and the second contact 60 in the front-rear direction. Therefore, since the elasticity of the movable pieces 42 and 62 resulting from the positional change of the cam part 73, and the fluctuation | variation of the lifting amount can be prevented, the contact pressure of each contact 40 and 60 with respect to the FPC80 is prevented. However, fluctuations in contact resistance can be prevented.

In addition, since the fall prevention projections 46 and the cam portion 73 are independent (because of the non-contact structure), the fall prevention projections 46 are prevented from coming into contact with the cam portion 73 by the fall prevention projections 46. There is no fear that the cam portion 73 becomes small.

Furthermore, since the fall prevention recess 74 is a recess independent from (not in communication with) the fall recess 72, the width of the fall prevention recess 74 (which affects the fall recess 72) is affected. Can be set separately, and it is not necessary to make it wide in accordance with the recessed recess 72.

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

For example, you may change the 2nd contact insertion groove 27 of the whole insulator 20 into the 1st contact insertion groove 25, and the whole contact may be comprised by the 1st contact 40. FIG.

Further, when the actuator 70 moves to the unlocked position or the locked position by positioning the flat (horizontal) upper surface of the rear portion of the fixing piece 41 of the first contact 40 above the flat surface 28, the actuator 70 ), The locking holding surface 75 or the loosening holding surface 76 may be brought into surface contact with the upper surface (flat surface) of the rear portion of the high piece 41.

Further, by removing the walls located between the adjacent anti-separation recesses 74, a long anti-seizure recess extending from the actuator 70 in the horizontal direction may be formed.

Moreover, you may comprise the actuator 70 so that the protrusion line 77 may be located ahead of the cam part 73 when the actuator 70 rotates to the position of FIG. 10, FIG. In this case, when the actuator 70 rotates to the positions shown in Figs. 10 and 11, the actuator 70 generates a rotation moment toward the locked position, so that the actuator 70 reliably rotates to the locked position.

Moreover, a cable other than FPC, for example, a flexible flat cable (FFC), may be sufficient as the connection object on a thin plate. The contact object 81a, 82a may be brought into contact with each of the contact protrusions 44, 65 by inverting the connection object in contrast to the above embodiment, and the contact portion may be formed on both front and back sides of the connection object, and the actuator 70 The contact protrusions 44, 49, 65 and 67 may be brought into contact with the respective contact portions when the door moves to the locked position.
