Abstract

PROBLEM TO BE SOLVED: To provide a low-profile connector which enables easy insertion/extraction of a flat conductor.SOLUTION: A connector 1 comprises: a terminal 4 which is brought into conduction and contact with a flat conductor 2; a housing 3 which holds the terminal 4; and a lock member 5 which is pivotally supported by the housing 3 in a rotatable manner, and which has a locking part 5d1 which is locked to a locking edge 2a1 of the flat conductor 2 by rotation so as to prevent the flat conductor 2 from coming out of the housing 3. An operation part 5e of the lock member 5 is arranged above a board connection part 4a of the terminal 4. Because the operation part 5e is pressed and displaced toward the board connection part 4a, the connector 1 may have a lower profile compared with a case where the operation part 5e is arranged on the housing 3.SELECTED DRAWING: Figure 17

Description

  The present invention relates to a connector including a lock member that fixes a connection object.

  As a connector mounted on a board, one having a lock member for fixing a connection object in order to maintain a conductive connection state with the connection object is known. Such a locking member is attached to the housing of the connector, and the connection object can be fixed only by inserting the connection object into the fitting chamber. In addition, since the locking to the connection object can be released by a simple operation such as pressing the lock member, the connection object can be easily removed from the connector (see Patent Document 1 as an example).

JP 2014-22214 A

  By the way, in recent years, electronic devices in various fields such as smartphones and in-vehicle electronic devices have been downsized. Therefore, it is required to reduce the height of each component mounted on such an electronic device in order to effectively use the space.

  As the lock member provided in the connector, there is one disposed on the upper side of the top surface portion of the housing. The lock can be released by pressing such a lock member toward the top surface of the housing. Since it is necessary to provide a displacement space for the lock member to displace between the top surface portion, the height from the bottom surface portion of the connector to the upper portion of the lock member becomes higher, and the height of the connector increases as a whole. . For this reason, there is a limit to reducing the height of a conventional connector including a lock member.

  The present invention has been made against the background of the prior art as described above. The object is to provide a low profile connector including a locking member for fixing a connection object.

  In order to achieve the above object, the present invention is configured as follows.

  That is, the present invention relates to a housing having a flat conductor insertion port and a back wall portion facing the insertion end of the flat conductor, and is in conductive contact with the flat conductor inside the housing, so that the outside of the back wall portion. And a terminal having a board connecting portion that protrudes toward the board and is connected to the board, and is pivotally supported with respect to the housing. The flat conductor is fixed to the locking edge of the flat conductor by turning. A connector including a lock member having a locking portion for preventing the housing from coming off from the housing, wherein the lock member has an operation portion that is disposed above the board connection portion of the terminal and pressed toward the board connection portion. A connector is provided.

  The operation part of the lock member is arranged above the terminal board connection part of the terminal protruding from the back wall part of the housing, so that the operation part has a low profile as compared with the case where the operation part is arranged on the upper part of the housing. Connector. Further, the entire connector can be reduced in size in the insertion direction as compared with the case where the flat conductor is disposed further to the back side than the board connection portion. Furthermore, since such an operation part is pressed toward the board connection part, it is not necessary to arrange a displacement space for displacing the operation part above the housing. As a result, the overall height of the connector can be reduced.

  The operation part of the present invention may be located between the board connection part of the terminal and the upper surface of the housing.

  By preventing the operation portion from protruding above the upper surface of the housing, the connector can be more reliably reduced in height.

  The housing of the present invention may include a support spring portion that urges the operation portion upward.

  By doing so, after pressing the operating portion toward the board connecting portion, the operating portion can be returned to the position before pressing by the support spring portion. Therefore, the operation | work which an operator operates an operation part can be abbreviate | omitted.

  The lock member of the present invention has an arm portion that supports the locking portion, and the locking portion is accommodated in the housing, and the locking portion is displaced upward so that the arm portion is It can protrude from the upper surface of the housing.

  By doing so, when the connection object is inserted into the housing, the locking portion is pressed from the flat conductor and displaced upward, and the arm portion can be protruded from the upper surface of the housing. After that, when the locking portion is locked to the locking edge, the arm portion returns to the original position by being displaced downward, and the protruding portion is eliminated, so that the operator can check whether the protruding portion is present. It is possible to confirm that the locking of the flat conductor has been completed. Thereby, generation | occurrence | production of the half fitting with respect to the housing of a flat type conductor can be suppressed.

  The locking member of the present invention may have an inclined portion that is inclined upward from the near side to the far side in the insertion / extraction direction of the connection object on the lower end side.

  By doing so, even when the operation unit is pressed toward the board connection part, it is difficult to cause a situation in which a part of the lock member comes into contact with another member such as the board and cannot be sufficiently rotated. can do.

  According to the connector of the present invention, it is possible to provide a low-profile connector having a lock member that can easily insert and remove a flat conductor. Therefore, it is possible to contribute to a reduction in the height of the mounted electronic device.

  Hereinafter, an embodiment of a connector of the present invention will be described with reference to the drawings.

  In the present specification, claims, and drawings, the width direction along the arrangement direction of the terminals 4 of the connector 1 is the X direction, the front-rear direction along the insertion / removal direction of the flat conductor 2 is the Y direction, and the height direction is the Z direction. To do. Further, the plane side in the height direction Z is referred to as “upper side”, and the bottom side is referred to as “lower side”. Further, in the front-rear direction Y, the front side in the insertion direction of the connection object is “front”, and the back side in the insertion direction is “rear”. Such identification of the upper and lower sides and the front and rear does not limit the mounting direction and usage direction of the connector of the present invention. In addition, about the connector 1, since the left view is represented as right-and-left symmetry with the right view, description is abbreviate | omitted.

Embodiment [FIGS. 1 to 19]:
The connector 1 is mounted on the board P and electrically connects the board pattern of the board P and the flat conductor 2. In the present embodiment, the flat conductor 2 is inserted along the surface of the substrate P with the substrate P placed flat. As shown in FIGS. 1 to 7, the connector 1 includes a housing 3, a plurality of terminals 4, a lock member 5, and a support spring portion 6.

  In the present embodiment, a flat conductor 2 such as an FFC (Flexible Flat Cable) or an FPC (Flexible Printed Circuits) will be described and described as an example of the “connection object”. As shown in FIG. 15, the flat conductor 2 has one notch portion 2 a for locking at both ends in the width direction X. The notch 2a has a locking edge 2a1, and a locking part 5d1 described later is locked to the locking edge 2a1. Further, these two notches 2a are formed at the same position in the front-rear direction Y.

〔housing〕
The housing 3 is made of an insulating resin and is formed in a substantially rectangular parallelepiped shape. As shown in FIGS. 1 to 7, such a housing 3 has a top wall portion 3a, a bottom wall portion 3b, a side wall portion 3c, and a back wall portion 3d. Further, inside the housing 3, a fitting chamber 3e that is formed by the top wall portion 3a, the bottom wall portion 3b, the two side wall portions 3c, and the back wall portion 3d and accommodates the flat conductor 2; The fitting chamber 3e has an insertion port 3f through which the flat conductor 2 is inserted.

  The top wall 3a has an XY plane. A concave portion 3a1 is formed on the rear side of the top wall portion 3a, and the substrate connecting portion 4a of the terminal 4 is exposed from the concave portion 3a1. One slit 3a3 is provided on both sides in the width direction X on the upper surface 3a2 of the top wall 3a. The slit 3a3 is formed as a cut along the front-rear direction Y, and communicates with the fitting chamber 3e. The slit 3a3 accommodates a lock piece 5d of the lock member 5 described later. Thus, by providing the slit 3a3 for accommodating the lock piece 5d in the top wall 3a, the height of the connector 1 as a whole can be reduced as compared with the case where the housing space is provided inside the housing 3, for example. it can. Further, since the lock piece 5d is displaced up and down inside the slit 3a3, it is not necessary to provide a displacement space for the lock piece 5d to be displaced up and down in the housing 3 itself. Therefore, the whole connector 1 can be made low-profile.

  The bottom wall portion 3b is disposed to face the top wall portion 3a. A concave portion 3b1 is formed on the rear side of the bottom wall portion 3b, and the substrate connecting portion 4a of the terminal 4 is exposed from the concave portion 3b1. Such a bottom wall portion 3b faces the surface of the substrate P in a state where the connector 1 is mounted on the substrate P.

  One side wall 3c is disposed on each side of the connector 1 in the width direction X, and is connected to the top wall 3a and the bottom wall 3b. The side wall portion 3c is provided with a support portion 3c1 that protrudes along the width direction X. The support portion 3c1 is inserted into an attachment hole 5a1 of the lock member 5 described later. Further, a groove 3c2 is formed in the side wall 3c. A housing fixing portion 6a of the support spring portion 6 is press-fitted and fixed in the groove portion 3c2.

  The back wall portion 3 d is disposed on the rear side of the housing 3. A plurality of fixing holes (not shown) for the terminals 4 are provided in the back wall 3d. The insertion port 3f is disposed at the front end of the housing 3 and communicates with the fitting chamber 3e. The flat conductor 2 inserted from the insertion port 3f is in conductive contact with the terminal 4 inside the fitting chamber 3e.

(Terminal)
The terminal 4 is formed by punching a conductive metal plate. As shown in FIGS. 16 and 17, the terminal 4 includes a board connecting portion 4a, a fixing portion 4b, and a contact portion 4c in order from one end side. The board connecting portion 4a is fixed to the board P by soldering. The fixing portion 4b is provided so as to be connected to the board connecting portion 4a, and is fixed by being press-fitted into a fixing hole (not shown) provided in the back wall portion 3d of the housing 3. The contact part 4c is connected to the fixed part 4b, and a contact part 4c1 of the contact part 4c protrudes into the fitting chamber 3e from a slit (not shown) provided on the inner wall of the fitting chamber 3e. The contact portions 4c are formed by extending two from the fixed portion 4b, and can be in conductive contact with the flat conductor 2 so as to be sandwiched from above and below. As described above, the flat conductor 2 that is the “connection object” of the present embodiment has conductive portions (not shown) on both the front and back surfaces, and the terminal 4 has the contact portion 4c1 that is in conductive contact with each conductive portion on the upper side. And on the lower side. However, such a configuration is not essential, and when the flat conductor 2 has a conductive portion only on either the front surface or the back surface, only the upper or lower contact portion 4c1 corresponding to the conductive portion is provided. You may have.

(Lock member)
The lock member 5 is for locking the flat conductor 2 so as not to come out of the connector 1 and improving the connection reliability of the flat conductor 2. As shown in FIGS. 8 and 9, the lock member 5 is formed by bending a metal piece, and includes a housing fixing portion 5a, a cover portion 5b, a connecting portion 5c, a lock piece 5d, and an operation portion 5e. Have

  One housing fixing portion 5 a is provided on each end in the width direction X of the lock member 5. The housing fixing portion 5a has a YZ plane, and has a mounting hole 5a1 at the approximate center thereof. A support 3c1 provided on the side wall 3c of the housing 3 is inserted into the mounting hole 5a1. Thus, the lock member 5 is pivotally supported with respect to the housing 3. The housing fixing portion 5a can be rotated with the axis connecting the two support portions 3c1 as the rotation axis A in a state where the support portion 3c1 is inserted into the mounting hole 5a1. In the connector 1 of the present embodiment, the housing 3 has a projecting support portion 3c1, and the lock member 5 has an attachment hole 5a1 that is a through hole. However, the configuration is not limited to the above as long as the lock member 5 is pivotally supported by the housing 3. That is, the housing 3 may have such mounting holes, and the lock member 5 may have a protruding shape for mounting.

  In addition, an inclined portion 5a2 that is inclined upward from the front side to the rear side is provided at the lower end of the housing fixing portion 5a.

  The cover part 5b is a plate-like part connected to the housing fixing part 5a. The cover portion 5b is formed so as to cover the support spring portion 6 included in the side wall portion 3c of the housing 3 from above. An abutting portion 5b1 that is pressed from a supporting spring portion 6 described later is provided on the lower surface of the cover portion 5b and on the rear side in the front-rear direction Y with respect to the supporting portion 3c1 of the housing 3.

  The connecting portion 5c is a plate-like portion connected to the cover portion 5b and having a YZ plane. An inclined portion 5c1 that is inclined upward from the front side to the rear side is provided at the lower end of the connecting portion 5c, similarly to the housing fixing portion 5a.

  The lock piece 5d is formed in a cantilever shape connected to the connecting portion 5c, and the lock piece 5d of the present embodiment particularly extends in the forward direction. The lock piece 5d is provided with an arm portion 5d3 and a locking portion 5d1 protruding downward from the tip of the arm portion 5d3. Further, the locking portion 5d1 has a mountain shape, and a guide edge 5d2 that is inclined from the lower side to the upper side is formed on the tip side thereof. Since each lock piece 5d has one locking portion 5d1, the lock member 5 has two locking portions 5d1 as a whole. These locking portions 5d1 and 5d1 are arranged at the same position in the front-rear direction Y. When the lock member 5 rotates about the rotation axis A, the locking portion 5d1 is displaced in the vertical direction.

  The operation portion 5e is provided on the rear side of the connecting portion 5c and is a plate-like piece that extends along the width direction X. On the upper part of the operation unit 5e, an operation surface 5e1 that is a surface along the XY plane and for performing a pressing operation is provided. In addition, since one operating portion 5e is formed by being connected to two connecting portions 5c, the lock by the two locking portions 5d1 can be released by operating the operating portion 5e.

  Furthermore, the operation part 5e is arranged behind the back wall part 3d of the housing 3 and above the board connection part 4a of the terminal 4 exposed from the recesses 3a1 and 3b1. By adopting such an arrangement, for example, the connector 1 can be made low overall as compared with the case where the operation part 5e is arranged above the top wall part 3a of the housing 3. In addition, the connector 1 can be reduced in size in the front-rear direction Y as compared with the case where the operation unit 5e is disposed further rearward of the board connection unit 4a. Furthermore, by providing the housing 3 with the recesses 3a1 and 3b1, it is possible to secure a space for disposing the operation portion 5e of the lock piece 5d. Therefore, for example, the connector 1 can be reduced in size in the front-rear direction Y as compared with the case where the operation portion 5e is disposed behind the housing 3 without providing the recesses 3a1 and 3b1.

  The operation surface 5 e 1 is disposed below the upper surface 3 a 2 of the top wall portion 3 a of the housing 3. The lock member 5 can be rotated by pressing the operation part 5e along the height direction Z toward the board connection part 4a. Since no structure is provided between the operation unit 5e and the substrate connection unit 4a to inhibit the displacement of the operation unit 5e during the pressing operation, the operation unit 5e can be sufficiently pressed. Further, the operating portion 5e is displaced in the height direction Z between the board connecting portion 4a and the upper surface 3a2 of the top wall portion 3a, thereby providing a displacement space for the operating portion 5e above the housing 3 or inside the housing 3. Compared with the case, the connector 1 can be made low-profile as a whole.

[Support spring]
The support spring portion 6 is formed by punching a metal plate. In particular, as shown in FIGS. 18 and 19, the support spring portion 6 of the present embodiment is substantially U-shaped as a whole, and has a housing fixing portion 6a, a spring portion 6b, and a pressing piece 6c from one end side. . The housing fixing part 6a is press-fitted and fixed in a groove part 3c2 that the side wall part 3c of the housing 3 has. Therefore, the connector 1 of this embodiment includes two support spring portions 6.

The spring portion 6b is formed to be bent in a substantially U shape that protrudes toward the operation portion 5e in the front-rear direction Y. Since the spring portion 6b is elastically deformed along the plate surface, it can support the lock member 5 with a stronger restoring force.

  The pressing piece 6c has an elastic piece portion 6c1 and a pressing portion 6c2 elastically supported by the elastic piece portion 6c1. The elastic piece 6c1 has a cantilever shape extending from the spring 6b. The pressing portion 6c2 is disposed directly below the contact portion 5b1 included in the cover portion 5b of the lock member 5. The pressing portion 6c2 has a mountain shape protruding upward, and presses and contacts the contact portion 5b1 upward.

[Description of flat conductor insertion method]
As described above, the pressing portion 6c2 of the pressing piece 6c presses and contacts the contact portion 5b1 of the cover portion 5b upward. Further, in the front-rear direction Y, a locking portion 5d1 is disposed on the front side of the support portion 3c1, and an operation portion 5e is disposed on the rear side. Therefore, as shown in FIGS. 10 to 12, the lock member 5 rotates like a seesaw around the rotation axis A that connects the left and right support portions 3 c 1. That is, in the state where the operation part 5e and the cover part 5b provided on the rear side of the support part 3c1 are positioned on the upper side, the distal ends of the locking part 5d1 and the arm part 5d3 provided on the front side of the support part 3c1 are Located on the lower side. On the contrary, in the state where the operation part 5e and the cover part 5b are located on the lower side, the distal end side of the locking part 5d1 and the arm part 5d3 is located on the upper side.

  When the flat conductor 2 is inserted into the fitting chamber 3e with the engaging portion 5d1 entering the fitting chamber 3e, the distal end portion 2b of the flat conductor 2 comes into contact with the engaging portion 5d1 of the lock piece 5d (see FIG. 13). The locking portion 5d1 has a guide edge 5d2 on the front side, and the tip portion 2b of the flat conductor 2 moves so as to slide along the guide edge 5d2, while lifting the locking portion 5d1 upward. As a result, the flat conductor 2 passes below the flat conductor 2 while being pressed downward by the locking portion 5d1. In this state, the contact portion 5b1 on the rear side of the support portion 3c1 in the cover portion 5b is displaced downward as opposed to the locking portion 5d1. Therefore, the support spring part 6 that is in contact with the contact part 5b1 is elastically deformed so as to be pressed and compressed downward (see FIG. 18). Thus, a restoring force is applied from the pressing portion 6c2 to the contact portion 5b1 in an upward direction.

  Thus, in a state where the locking portion 5d1 is displaced upward by the flat conductor 2, the lock piece 5d is displaced upward as a whole. At that time, the distal end side of the arm portion 5d3 of the lock piece 5d protrudes upward from the slit 3a3 provided in the top wall portion 3a of the housing 3.

  In this state, due to the restoring force of the spring portion 6b of the support spring portion 6, the pressing portion 6c2 is in strong pressing contact with the contact portion 5b1 of the cover portion 5b upward. Therefore, when the flat conductor 2 is inserted to the back of the fitting chamber 3e, the lock piece 5d is rotated by the action of the spring force of the support spring portion 6, and the locking portion 5d1 is directed downward from the upper side of the flat conductor 2. To enter the notch 2a (see FIGS. 14, 15, and 19). At this time, since the operator can obtain a click feeling at hand, it can be confirmed that the fitting operation of the flat conductor 2 is completed. Further, the distal end side of the arm portion 5d3 protruding above the top wall portion 3a of the housing 3 is lowered to be accommodated in the slit 3a3. By adopting such a configuration, it is possible to visually confirm that the engaging portion 5d1 of the lock piece 5d has entered into the cutout portion 2a of the flat conductor 2 and is locked, and the fitting operation has been completed. Therefore, it is possible to suppress the occurrence of a situation in which a half-fitting is used and a conduction failure occurs.

  When the flat conductor 2 is to be pulled out from the fitting chamber 3e in this state, the locking portion 5d1 is locked to the locking edge 2a1. Even when the fitting operation is completed, the pressing portion 6c2 of the support spring portion 6 is in press contact with the contact portion 5b1 of the cover portion 5b, so that the locking portion 5d1 is biased downward. The flat conductor 2 is strongly locked. Therefore, the flat conductor 2 can be reliably prevented from coming off from the housing 3.

[Explanation of flat conductor removal method]
When the flat conductor 2 is removed from the housing 3, the operation portion 5e is pressed downward. The operation surface 5e1 of the operation unit 5e is disposed below the upper surface 3a2 of the top wall 3a of the housing 3 as described above. Therefore, even if the operator uses it in an environment where visual inspection is difficult due to, for example, the connector 1 having a small size or a dense mounting component around it, it can be locked only with the sense of the hand. The operation part 5e of the member 5 and the top wall part 3a of the housing 3 can be distinguished.

  As described above, the lock member 5 rotates about the rotation axis A by operating the operation unit 5e. Since the inclined portion 5a2 is provided at the lower end of the housing fixing portion 5a and the inclined portion 5c1 is provided at the connecting portion 5c, the housing fixing portion 5a and the connecting portion 5c can be connected even when they are lowered downward. It is difficult to cause a situation in which the part 5c contacts the substrate P and is prevented from rotating. Thereby, the lock member 5 can fully rotate. Further, by providing the inclined portions 5a2 and 5c1, the lock member 5 is mounted at a high position in the housing 3 so as not to come into contact with the substrate P when the housing fixing portion 5a rotates. There is no need to let them. Therefore, the overall height of the connector 1 can be further reduced.

  In this way, the locking portion 5d1 is displaced upward and separated from the cutout portion 2a of the flat conductor 2, whereby the lock is released. In this state, the support spring portion 6 is pressed downward by the cover portion 5b and elastically deformed so as to be compressed (see FIG. 18). Thereafter, due to the restoring force of the support spring portion 6, the pressing portion 6c2 is pressed upward against the contact portion 5b1 of the cover portion 5b of the lock member 5 (see FIG. 19).

  The flat conductor 2 is removed from the fitting chamber 3e of the connector 1 in the unlocked state. Thereafter, when the pressing of the operation portion 5 e is stopped, the cover portion 5 b of the lock member 5 is lifted upward by the support spring portion 6. At the same time, the lock piece 5d is lowered to be accommodated in the slit 3a3 of the top wall 3a of the housing 3, and the locking portion 5d1 returns to the position inside the fitting chamber 3e. The rotation of the lock piece 5d is performed by the support spring portion 6 without being operated by the operator.

  As described above, according to this embodiment, the low-profile connector 1 can be realized while including the lock member 5. Therefore, the flat conductor 2 can be attached and detached, exhibiting high convenience, and a connector 1 that contributes to downsizing of an electronic device or the like to be mounted.

Variations:
In the embodiment, the example in which the locking portions 5d1 included in the two lock pieces 5d of the lock member 5 are arranged at the same position in the front-rear direction Y is shown. On the other hand, the latching | locking part 5d1 which the lock member 5 has can be arrange | positioned in the position which differs in the front-back direction Y. In this case, as the flat conductor 2, a notch portion 2a provided on both ends in the width direction X is a position that is different in the front-rear direction Y and is disposed at the same position as the locking portion 5d1. By using the flat conductor 2 having the notches 2a at different positions in the front-rear direction Y as described above, it is possible to prevent the flat conductor 2 from being inserted in the wrong direction on the front and back. Such a configuration is particularly effective when the terminal 4 of the connector 1 has the contact portion 4c1 only on either the upper side or the lower side.

  In the above-described embodiment, an example in which the support spring portions 6 are provided in total, two at each of both end sides in the width direction X of the housing 3 has been described. On the other hand, the connector 1 may include only one support spring portion 6. For example, it can arrange | position in the center in the width direction X. In this case, a contact portion is formed at the center of the operation portion 5e in the width direction X, and the contact portion is pressed upward by the pressing portion 6c2, so that the lock piece 5d is lowered to the flat conductor. 2 may be locked. By setting it as such a structure, compared with the case where multiple support spring parts 6 are provided, a number of parts can be reduced. Moreover, it can be set as the connector 1 of a simpler structure.

  In the said embodiment, the example which consists of a leaf | plate spring which punched the metal plate as the support spring part 6 elastically deformed along the direction parallel to the plate | board surface of a metal plate was shown. On the other hand, the support spring portion 6 may have another shape as long as the lock member 5 can be rotated. Therefore, for example, it can be formed as a leaf spring that is elastically deformed along the thickness direction. Moreover, the support spring part 6 can also be formed as a wound spring.
