Description

Connector {Connector}

The present invention relates to a connector for electrically conducting a plate-shaped connection object such as a flexible printed circuit board (FPC) or a flexible flat cable (FFC) to the substrate.

In general, as a type of connector for electrically connecting a flat connection object with a substrate, a ZIF (Zero Insertion Force) type that increases the contact pressure between the contact and the connection object by using an actuator, or a connection object without using an actuator The NON-ZIF type is known to increase the contact pressure by using a contact gap narrower than the thickness of.

However, ZIF-type connectors that are very low (e.g., about 0.5 mm in height) and have fewer poles of contact can obtain contact pressure by the actuator as well as during insertion of the contact object and until contact pressure is obtained by the actuator. Since it is difficult to obtain sufficient force for preventing the connection object from coming out afterwards, the connection object may suddenly come out of the connector. In addition, the connector of the NON-ZIF type which is very low and the number of poles of the contact is small also has the same problem that it is difficult to obtain the force enough to hold the contact object only by the contact pressure by the contact.

On the other hand, there is one disclosed in Japanese Patent Application Laid-Open No. 2007-95594 as a connector which prevents the connection object from suddenly exiting from the connector even with a very low connector and a few poles of contacts.

As shown in FIG. 18, the connector 10 includes an insulator (insulation housing) 11, a plurality of metal contacts (terminals) 13 arranged side by side in one direction inside the insulator 11, and a contact 13. And a pair of engaging members 12 provided inside the insulator 11 and a rotary actuator (pressing member) 14 rotatably provided with respect to the insulator 11. The pair of catching members 12 are fixed parts 21 fixed to the insulator 11 and elastically deformable point portions extending from the middle of the fixed parts 21 in a direction orthogonal to the fixed parts 21. (22) and a lever-shaped arm portion 20 and an extension portion 20B extending from the end portions on the opposite side of the fixed portion 21 of the branch portion 22 in the opposite directions. In addition, at the distal end of the lever-shaped arm 20, a locking claw 20A protrudes downward from the notch C1 formed at both edges of the flat cable C (connection object).

When the flat cable C is inserted into the insulator 11 in this manner, the tip of the flat cable C contacts the locking claw portion 20A of the locking member 12 to elastically deform the lever-shaped arm 20. The locking claw 20A is in contact with the surface of the flat cable C. And if the flat cable C is further inserted in the insulator 11, and the notch C1 of the flat cable C moves to the position which opposes the latching claw part 20A of the lever-shaped arm part 20, The latching claw portion 20A is coupled to the notch C1 of the flat cable C while the lever-shaped arm 20 elastically returns to its initial shape.

In this way, in the locked state in which the locking claw portion 20A of the pair of lever-shaped arm portions 20 is coupled to the pair of notches C1 of the balanced cable C, the actuator 14 is insulated from the insulator 11. When it rotates to the closed position parallel to and the actuator 14 comes into contact with the extension part 20B of the locking member 12, the locking claw 20A of the lever-shaped arm part 20 exits from the notch C1. The deformation in the direction is regulated, whereby the locked state is maintained (the fall off of the insulator 11 of the flat cable C is prevented).

However, the conventional connector 10 has the following problems.

That is, even when the actuator 14 is moved to the open position (unlocked position) after the latching claw portion 20A of the lever-shaped arm portion 20 is engaged with the notch C1 of the flat cable C, the notch C1 is engaged. Since the engagement state of the claw portion 20A is maintained, in order to pull out the flat cable C from the inside of the insulator 11, the point portion 22 is elastically deformed so that the locking claw portion 20A of the lever-shaped arm portion 20 is closed. The balanced cable C must be pulled with a strong force to exit the notch C1.

Therefore, when the flat cable C is pulled out from the insulator 11, the flat cable C and the catching claw portion 20A are in contact with each other by a strong force, and thus the catching member 12 (lever arm 20) A large (excessive) load is applied to the flat cable C, so that the flat cable C may be cut, broken, or deformed in the locking member 12.

In addition, the connector 10 in the state before connecting the flat cable C moves the actuator 14 to the closed position (locked position) from the viewpoint of convenience on packing and mounting on the substrate. In order to insert the flat cable (C) into (11), the actuator 14 must be rotated to the open position (unlocked position) once, and after inserting the balanced cable (C), the actuator 14 is closed (locked position). It is very cumbersome to connect the flat cable (C) to the connector 10 because it has to be returned.

It is an object of the present invention to ensure that the connection object suddenly escapes from the insulator even when the number of poles is very low and the contact number is small, and the connection object can be intentionally removed from the insulator without applying load to the connection object and the lock member. The present invention provides a connector that can be easily pulled out and can easily perform a connection work with a connection object.

An insulator capable of inserting and removing a plate-shaped connection object having a caught portion formed of a catching hole or a notch formed in the peripheral edge portion thereof; A contact provided in the insulator and electrically connected to the connection object by contacting the connection object; A lock arm installed in the insulator, the lock arm having a locking claw, and a lock allowing the locking claw to engage with the hooked portion of the connection object inserted in the insulator while moving integrally with the lock arm; A lock member positioned at a position, the lock member having a pressurized piece for releasing the catching claw from the caught portion when moving to the lock release position; And an actuator which is selectively installed in contact with the pressurized piece of the lock member to move the pressurized piece to the lock release position when contacting the pressurized piece.

The lock member includes an elastic deformable portion, the lock arm extending in the opposite direction from the elastic deformable portion, and the pressed member, and the elastic deformable portion is elastically deformed so that the lock arm and the pressed member are elastically deformed. It is preferably configured to rotate integrally around the deformable portion.

Further, the actuator is rotatably supported on the bearing portion formed in the contact, insulator or lock member, and is connected to the pressurized piece while being perpendicular to the non-pressurized position and the connecting object being parallel to the connecting object and spaced apart from the pressed object. It may be a rotary actuator that rotates between the pressing positions in contact.

In addition, the actuator may be slidably installed with respect to the insulator, and may be a slide type actuator which, in the inserted state, moves the to-be-pressed piece positioned at the lock allowable position to the lock release position by contacting the to-be-pressed piece.

When the connection object is inserted into the insulator of the connector of the present invention, the locking claw of the lock arm of the lock member is automatically engaged with the caught portion (locking hole or notch) of the connection object, so that the number of poles of the contact or the connector is very small. Even when it is difficult to hold the contact object only by the contact pressure, such as in the case of light and simple, it is possible to reliably prevent the connection object from suddenly coming out of the insulator and improve the insertion workability of the contact object.

In addition, if the actuator is moved until it comes into contact with the pressing member of the lock member, the locking claw of the lock arm escapes from the caught portion of the connection object, so that the connection object can be smoothly removed from the connector without applying a load to the connection object and the lock member. It can be taken out easily.

According to the invention as set forth in claim 2, when the actuator presses the pressing piece of the lock member, the elastic deformation portion is elastically deformed so that the pressing piece and the lock arm are integrally rotated around the elastic deformation portion, thereby realizing low magnification of the lock arm. The engagement claw and the caught portion of the connection object can be reliably released.

According to the invention as set forth in claim 3, the actuator is constituted by a rotary actuator, so that the pressure before the rotary actuator connects the connection object to the connector while being parallel to the connection object in terms of convenience of packaging and mounting on the substrate. It may be located in a non-pressing position spaced apart from the squeezing piece.

Therefore, it is possible to insert the connection object into the connector in the state immediately after mounting the substrate (without rotating the rotary actuator to the pressing position) and to maintain this state. In other words, it is not necessary to rotate the rotary actuator to the pressing position in order to maintain the connection state between the connection object and the connector, and thus the connection work of the connection object to the present connector can be performed very easily.

According to the invention as set forth in claim 4, by constituting the actuator with the slide type actuator, the connector can be made low even when the connection state between the connection object and the connector is maintained or when the connection state is released.

The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings.

The contact 40 is an integral body obtained by stamping molding, and is plated on a substrate (eg, phosphor bronze, beryllium copper, titanium copper, stainless steel, corson-based copper alloy) obtained through stamping molding (for example, nickel). After (Ni) plating, it is an electroconductive member manufactured by performing finish plating (for example, gold plating, tin (Sn)-copper (Cu) plating, tin (Sn)-lead (Pb) plating).

The contact 40 has a lower conducting arm 42 having a vertical fixing protrusion 41 and a straight extension extending forward from the lower end of the fixing protrusion 41 and an upwardly contacting protrusion 43 at its distal end. And an upper conductive arm 44 extending upwardly from the middle portion of the lower conductive arm 42 and extending forward, and having a downward contact protrusion 45 at its distal end, and the fixing protrusion 41. Tail portion 46 extending linearly from the lower end toward the rear and pressing portion 47 having a dimension shorter than tail portion 46 extending upward from the middle portion of tail portion 46 once extending upwards. Equipped with.

As shown in Figs. 6, 8, 10 and the like, the contacts 40 having such a structure are fitted into and fixed with corresponding fixing holes 27 formed in the insulator 20, and the upper conduction is performed. The arm 44 is fitted into the corresponding upper contact attaching groove 30, and the lower conductive arm 42 is fitted into the corresponding lower contact attaching groove 31 so as to be fixed inside the insulator 20.

Although not shown, a substrate having a horizontal plate shape is positioned directly under the insulator 20, and the tail portions 46 of the contacts 40 are connected to a plurality of conductive portions (contact terminals) formed on the upper surface of the substrate. Each is soldered.

The left and right lock members 50, which are integrally formed products made of metal, extend downward from the vicinity of the rear end portion of the fixing portion 51 forming a cross-sectional L-shape and the L-shape viewed from the front and the inner side of the upper portion of the upper portion of the fixing portion 51. The connecting arm part (elastic deformation part) 52, the to-be-pressed piece 53 extended linearly from the lower end part of the connection arm part 52 toward the rear, and extended upwards after extending forward from the lower end part of the connection arm part 52. And a lock arm 54 extending forward again. As shown in FIG. 4, the engaging projection 55 protrudes in the front and rear both end surfaces of the fixing part 51, respectively. Further, a downward locking claw 56 protrudes from the front end of the lock arm 54.

As shown in Figs. 1 to 3, the left and right lock members 50 having such a structure fit the fixing part 51 to the fixing recess 26 of the insulator 20 from above, and the front and rear latching is performed. The projection 55 is press-contacted to the front wall and the rear wall of the fixing recess 26, and the lower surface of the ceiling of the fixing portion 51 is placed on the upper surface of the insulator 20 (fixing recess 26 and storage recess ( 28) is fixed to both the left and right sides of the insulator 20 by contacting them. In addition, when the left and right lock members 50 are fixed to the insulator 20, as shown in FIGS. 7, 9, 11, and the like, the lock arm 54 (locking protrusion 55) is provided inside the storage recess 28. Located in

In addition, the connecting arm portion 52 of the lock member 50 is elastically deformable, and the press piece 53 and the locking projection 55 (locking claw 56) are viewed from the side by elastically deforming the connecting arm portion 52. It rotates integrally clockwise or counterclockwise about the connection arm part 52. As shown in FIG. That is, the to-be-pressed piece 53 and the lock arm 54 are located in the lock permissible position shown in FIG. 9 when the connection arm 52 is in a free state without applying any external force to the lock member 50. On the other hand, when the pressed member 53 of the lock member 50 is pushed downward (by the pressing surface 64 of the rotary actuator 60 described later), the pressed member 53 and the lock arm 54 are integrally sided. Since it rotates in a clockwise direction when viewed from, the to-be-pressed piece 53 and the lock arm 54 are positioned at the unlocking position shown in FIG. 11. In addition, if the pressurizing piece 53 and the lock arm 54 are rotated to the unlocking position and the pressing force on the press piece 53 is released, the connecting arm portion 52 returns to the free state. The projection 55 also automatically returns to the allowable position.

The rotary actuator 60 is injection molded of a heat resistant synthetic resin material.

The rotary actuator 60 includes a rectangular operation portion 61 in plan view and a cylindrical rotation shaft portion 62 extending from the front edge of the operation portion 61 to the left and right directions. Moreover, the recessed part 63 is formed in the vicinity of the left and right both ends of the rotating shaft part 62, and the bottom surface of this recessed part 63 becomes the press surface 64. As shown in FIG. In addition, four through holes 65 penetrating the operating portion 61 in the plate thickness direction are formed in the vicinity of the front end of the operating portion 61 side by side.

As shown in FIGS. 6, 8, and 10, the rotary actuator 60 having such a structure has the rotary shaft portion 62 between the front end portion and the pressing portion 47 of the tail portion 46 of each contact 40. A closed position (non-pressurized position) shown in FIGS. 6, 7, 8, 9, and the like rotatably mounted to the insulator 20 and each contact 40 by fitting to the bearing portion 48 formed in the It becomes possible to rotate between the open positions (pressing position) shown to FIG. 10, FIG.

Moreover, when the rotary actuator 60 is attached to the insulator 20 and each contact 40, the pressing part 47 of each contact 40 is fitted to the corresponding through-hole 65 so that relative movement is possible (FIG. 6, 8, and 10), and rear ends of the pressurized pieces 53 of the left and right lock members 50 are opposed to the left and right pressing surfaces 64 of the rotary actuator 60 (Figs. 7, 9, and 10). 11)

As shown in FIG.7 and FIG.9, when the rotary actuator 60 is located in a closed position, since the left and right press surface 64 does not contact the rear end of the left and right side to-be-pressed object 53, the lock arm 54 is shown. And the to-be-pressed piece 53 can rotate about the connecting arm portion 52 (see FIG. 7), and the to-be-pressed piece 53 and the lock arm 54 of each lock member 50 are positioned at the lock allowable position ( 9). On the other hand, when the rotary actuator 60 moves to an open position as shown in FIG. 11, since the left and right pressing surface 64 presses the rear end part of the left and right to-be-pressed object 53 downward, the connection arm part 52 elastically deforms. And the to-be-pressed piece 53 and the lock arm 54 rotate to the unlocking position.

Next, the method of inserting the FPC (flexible printed circuit board) 70 which is a connection object into the connector 10 of the said structure, and electrically connecting the FPC 70 and the said board | substrate through the contact 40 is demonstrated.

As shown to FIG. 7, FIG. 9, and FIG. 11, the notch (engaged part) 71 is formed in the intermediate part of the front-back direction of the left and right side parts of the FPC 70 of this embodiment, respectively. In general, the rotary actuator 60 is located in the closed position in advance as shown in Figs. 6 and 7 from the viewpoint of convenience of packing and mounting to a substrate.

6 and 7, when the rear end of the FPC 70 is inserted into the internal space of the insulator 20 from the front opening of the insulator 20, the rear end of the FPC 70 is in contact with each contact 40. It enters between the projection 43 (lower conduction arm 42) and the contacting projection 45 (upper conduction arm 44). At this time, each contact 40 is in a free state, and the distance between the contact protrusion 43 and the contact protrusion 45 is narrower than the thickness of the plate of the FPC 70. Therefore, as shown in FIG. 6, when the rear end part of the FPC 70 enters between the contact protrusion 43 and the contact protrusion 45, the lower conduction arm 42 and the upper conduction arm 44 may be slightly elastic downward and upward, respectively. The contact protrusion 43 and the contact protrusion 45 elastically contact the lower surface and the upper surface of the FPC 70, respectively.

In addition, when the rear end of the FPC 70 is inserted into the inner space of the insulator 20 as described above, the rear end surface of the FPC 70 is provided on the front surface of the locking claw 56 of the lock arm 54 positioned at the lock allowable position. Contact (not shown). Then, the connecting arm 52 is elastically deformed so that the lock arm 54 and the press piece 53 rotate clockwise when viewed from the side with respect to the connecting arm 52. On the top of 70).

From this state, the FPC 70 is further pushed into the insulator 20 (moved to the rear), and as shown in FIG. 8, the rear end portion of the FPC 70 has a lower conduction arm 42 of each contact 40. When the contact projection 43 of the lower conduction arm 42 and the contact projection 45 of the upper conduction arm 44 reach the vicinity of the rear end portion of the gap between the upper conduction arm 44 and the upper conduction arm 44, the lower surface of the FPC 70. And the conductive portion (not shown) formed on the upper surface and the upper surface, respectively, so that the FPC 70 and the substrate are electrically connected through each contact 40.

In addition, the locking claws 56 of the left and right lock members 50 face the notches 71 on both sides of the FPC 70. Therefore, as shown in FIG. 9, the to-be-pressed piece 53 and the lock arm 54 return automatically to a lock permissible position by the elastic force of the connection arm part 52, and the left and right locking claws 56 are notch (left and right) 71) are automatically combined. In this locked state, the FPC 70 is prevented from suddenly exiting from the connector 10.

In this locked state, when the FPC 70 is to be removed from the insulator 20 for maintenance, module replacement, etc., the rotary actuator 60 may be rotated to the open position shown in FIGS. 10 and 11.

Then, as shown in FIG. 11, since the left and right pressing surface 64 of the rotary actuator 60 presses down the rear end part of the to-be-pressed piece 53 of the left and right lock members 50, the left and right lock members 50 The connecting arm 52 is elastically deformed, and the to-be-pressed piece 53 and the lock arm 54 positioned at the lock allowable position rotate to the lock release position. Then, the locking claw 56 exits upward from the notch 71 of the FPC 70 so that the FPC 70 can be pulled forward from the insulator 20.

Although not shown, after the rotary actuator 60 is returned to the closed position, the lock member 50 automatically returns to the lock allowable position.

As described above, the connector 10 of the present embodiment has a structure in which the locking claws 56 of the left and right lock members 50 are coupled to the notches 71 of the FPC 70. Height of about 0.5 mm) and the number of poles of the contact 40 (about four), that is, it is very difficult to obtain a sufficient holding force for holding the FPC 70 by the contact 40 alone, It is possible to reliably prevent the FPC 70 from suddenly exiting the insulator 20.

In addition, by rotating the rotary actuator 60 to the open position, the FPC 70 can be smoothly removed from the connector 10 without placing a large load on the FPC 70 and the lock member 50.

In the state before the FPC 70 is connected to the connector 10, in general, the closed actuator (non-pressurized) in which the rotary actuator 60 is parallel to the FPC 70 from the viewpoint of convenience of packing and mounting on the substrate. Position), the FPC 70 can be inserted (connected) into the connector 10 without any manipulation of the rotary actuator 60. In addition, when the connection state between the FPC 70 and the connector 10 is maintained, it is not necessary to rotate the rotary actuator 60 to the open position (pressing position), so that the connection of the FPC 70 to the connector 10 is performed. The work is done very easily.

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

For example, as shown in FIGS. 12-17, you may implement by attaching the sliding actuator 80 to the connector 10 'instead of the rotary actuator 60. FIG.

The slide actuator 80 includes four insertion portions 81 extending forwardly from the rear end and a pair of pressing portions 82 extending forwardly from both left and right sides of the rear end. At the front end of the insertion portion 81, a coupling protrusion 83 having a circular cross section is formed.

In addition, the pressing part 47 of this modification is a dimension longer than the thing of the said embodiment, and the lower surface of the pressing part 47 has a front-rear pair of 1st holding recessed part 47a and the 2nd holding recessed part 47b. ) Is formed concave.

The sliding actuator 80 inserts each insertion portion 81 into a gap between the tail portion 46 and the pressing portion 47 of the corresponding contact 40, and each engagement projection 83 is used for the first holding. It is elastically coupled to any one of the recessed part 47a and the 2nd holding recessed part 47b, and is slidably attached to each contact 40 (insulator 20) in the front-back direction. When the engaging projections 83 are engaged with the first retaining recesses 47a of the contacts 40, the sliding actuator 80 has the left and right pressing portions 82 of the left and right locking members 50. It is held in a non-pressing position spaced backward from the pressing piece 53 (see Figs. 12-15). When the engaging protrusions 83 are coupled to the second retaining recesses 47b of the contacts 40, the sliding actuator 80 has the left and right pressing portions 82 of the left and right locking members 50. It moves to the pressing position which pushes the upper surface of the press piece 53 downward (refer FIG. 16 and FIG. 17).

In this modified example, in order to connect the FPC 70 to the connector 10 ', the FPC 70 is shown in a state in which the slide actuator 80 is positioned at a non-pressurized position as shown in Figs. It inserts into the insulator 20 to the position corresponded to 6 and FIG. Then, when the FPC 70 is inserted up to the position shown in Figs. 14 and 15 (positions corresponding to Figs. 8 and 9), the contact protrusion 43 and the contact protrusion 45 of the contact 40 are similar to the above embodiment. Is elastically contacted with the conductive portions on both the upper and lower sides of the FPC 70, and the locking claws 56 of the left and right lock members 50 are engaged with the notches 71 on the left and right sides of the FPC 70.

When the FPC 70 is to be taken out from the insulator 20 in this state, the slide actuator 80 is slid to the pressing position as shown in FIGS. 16 and 17. When the sliding actuator 80 is slid to the pressing position, as shown in FIG. 17, the left and right pressing portions 82 of the sliding actuator 80 move the pressed member 53 of the left and right lock members 50 downward. Since it presses, the to-be-pressed target piece 53 and the lock arm 54 which were located in the lock permissible position rotate to the lock release position shown in FIG.

Therefore, similarly to the above embodiment, the FPC 70 can be smoothly removed from the insulator 20.

In addition, when the actuator is the slide type actuator 80 as in the present modification, the connector 10 'can be made low in the case where the slide type actuator 80 is positioned at the pressed position and the non-pressed position.

In addition, although the conduction part is formed in the upper and lower surfaces of the FPC 70 in the said embodiment and the modified example, the conduction part is formed only in one surface, and one of the contact protrusion 43 and the contact protrusion 45 is connected to this conduction part. You may make it contact.

Further, the bearing portion of the rotary shaft portion 62 of the rotary actuator 60 and the holding portion (holding recess) of the engaging projection 83 of the slide actuator 80 are connected to the insulator 20 or the left and right lock members 50. It can also form and implement.

In addition, instead of forming the notch 71 in the FPC 70, a locking hole (a caught portion located inward from the peripheral edge of the FPC 70) penetrating the FPC 70 in the plate thickness direction is formed. You may also

In addition, a connection object may be other than FPC, for example, a flexible flat cable (FFC).
