Description

  The present invention relates to an electrical connector for a flat conductor that is disposed on a mounting surface such as a circuit board and to which a flat conductor is connected.

  As this type of connector, for example, Patent Document 1 discloses a flat conductor electrical connector in which a flat conductor is inserted and removed in a front-rear direction which is one direction parallel to a mounting surface of a circuit board. The connector of Patent Document 1 includes a housing extending in a direction perpendicular to the front-rear direction as a longitudinal direction, a plurality of terminals arranged and held in the housing with the longitudinal direction serving as a terminal arrangement direction, A lock operating member supported by the housing so as to be rotatable between a closed position allowing insertion of the flat conductor and an open position allowing extraction of the flat conductor from the housing; And a metal plate shell attached to the housing so as to cover the upper surface and both side surfaces.

  The housing is formed as a space in which a receiving portion for receiving a flat conductor is opened rearward. The lock operation member includes a lock plate portion having a plate surface perpendicular to the terminal arrangement direction at both end positions of the housing in the terminal arrangement direction, and a lock operation member that extends in the terminal arrangement direction and connects the lock plate portions to each other. And a release operation portion that protrudes radially from the rotation center of the shaft portion and extends to the positions of both lock plate portions in the terminal arrangement direction.

  In a state where the lock operation member is in the closed position, the lock plate portion extends forward from the position of the shaft portion, and the engagement lock portion protrudes downward on the lower edge of the lock plate portion. Is formed. On the front surface of the engagement lock portion, there is a front and rear locking surface for locking the flat conductor in a pull-out direction of the flat conductor after the flat conductor has been inserted. It is formed as a flat surface perpendicular to the direction. Further, on the rear surface of the engagement lock portion, a guide inclined surface for guiding the flat conductor in the insertion process forward is formed as an inclined surface that is inclined downward as it goes forward. On the upper edge of the lock plate portion, a pressing inclined surface that receives an urging force from a lock pressing portion of the shell, which will be described later, is formed as an inclined surface that inclines downward as it goes forward.

  Further, in a state where the lock operation member is in the closed position, the release operation part is located on the opposite side of the locking part from the shaft part, that is, behind the shaft part. Accordingly, when the release operation portion of the lock operation member in the closed position receives a downward pressing force as the release operation force, the release operation portion is moved downward and the lock lock portion is moved upward. The shaft portion is rotated about the rotation center so as to move to the open position.

  The shell has an upper plate portion that covers the upper surface of the housing, and is folded back and downward from the front edge of the upper plate portion at the same position as the lock plate portion in the terminal arrangement direction to press the lock operation member. It has a belt-shaped pressing arm that extends toward the inclined surface. The pressing arm portion can be elastically displaced in the plate thickness direction, and a lock pressing portion that elastically presses the pressing inclined surface of the lock operating member in the closed position from obliquely above is formed on the free end side. When the lock pressing portion presses the pressing inclined surface, the lock operating member is biased so as to be maintained at the closed position.

  In the flat conductor, a notch is formed in a side edge portion of the front portion, and a portion protruding toward the side in front of the notch functions as a locked portion. In the process of inserting the flat conductor into the receiving portion of the housing, the flat conductor first comes into contact with the guide inclined surface of the engagement lock portion of the lock operation member at the front edge of the locked portion, and The engagement lock portion is lifted against the urging force of the lock pressing portion. As a result, the lock operation member can be rotated so that the engagement lock portion is displaced upward and the release operation portion is displaced downward with the shaft portion as a rotation center, and the flat conductor can be continuously inserted. To do. Further, when the flat conductor is inserted and the locked portion reaches a predetermined position ahead of the engagement lock portion and the insertion is completed, the locking operation member is closed by the urging force from the lock pressing portion. Returning to the above, the lock engaging portion enters the cutout portion of the flat conductor from above. As a result, the locking surface of the lock engaging portion is positioned opposite to the rear edge of the locked portion of the flat conductor, and can be locked to the locked portion in the above-described extraction direction. Inadvertent removal of the flat conductor facing backward is prevented.

  Further, when the flat conductor is pulled out, a lock release operation is performed to press the release operation portion of the lock operation member downward, and the lock engagement portion is moved upward against the urging force from the lock press portion. In a state where the flat conductor is displaced from the cutout portion of the flat conductor, the flat conductor is pulled backward to be extracted.

JP2011-040295A

  In the flat conductor connector disclosed in Patent Document 1, the lock operation member always receives a biasing force toward the closed position from the lock pressing portion of the shell. Therefore, as described above, when the flat conductor is withdrawn, the lock engaging portion is displaced upward against the urging force to keep the lock operating member in the open position. During the operation, a downward pressing force must always be applied to the release operation portion against the urging force.

  Therefore, the operator usually pushes down the release operation part with one hand and maintains the state while holding the flat conductor with the other hand and pulls it out. As a result, the work of extracting the flat conductor becomes troublesome. In addition, when a sufficient space for performing the extraction operation with both hands is not secured around the flat conductor connector, the extraction operation becomes very difficult.

  This invention makes it a subject to provide the electrical connector for flat conductors which can extract a flat conductor easily in view of this situation.

An electrical connector for a flat conductor according to the present invention is an electrical connector for a flat conductor to which a flat conductor extending in the front-rear direction is connected, and at least rearward so that the flat conductor is inserted forward. A housing in which a receiving portion is formed as an open space, a plurality of terminals arranged and held in the housing with a direction perpendicular to the front-rear direction as a terminal arrangement direction, and the flat conductor to the housing The terminal arrangement in the terminal arrangement direction is supported by the housing or the terminal so as to be movable between a closed position that prevents extraction of the flat conductor and an open position that permits extraction of the flat conductor from the housing. A movable member having a locking portion that can be locked in the pulling-out direction of the flat conductor at the closed position with respect to the locked portion formed on the flat conductor at a position outside the range.

In such an electrical connector for a flat conductor, in the present invention, the housing or the attachment member attached to the housing has an engaging portion that engages with the movable member at a position outside the terminal arrangement range in the terminal arrangement direction. And the movable member has a corresponding engagement portion that engages with the engagement portion at the same position as the engagement portion in the terminal arrangement direction, and the engagement portion and the corresponding engagement portion are movable. When the member is switched to one of the closed position and the open position, the engaging portion biases the corresponding engaging portion, or the corresponding engaging portion biases the engaging portion. The movable member is engaged with each other so as to bring the movable member to the one position by a reaction force received from the engagement portion, and the corresponding engagement portion is changed from one position of the closed position and the open position to the other position. at switching moving process of the movable member toward the position, the movable A first corresponding engagement surface that receives an urging force toward the closed position from the engagement portion when the material is on the closed position side, and an urging force toward the open position when the movable member is on the open position side. A second corresponding engaging surface received from the engaging portion, and when the flat conductor is inserted into the receiving portion when the movable member is in the closed position, the flat conductor The movable member is moved toward the open position within a range in which the front end abuts against the locking portion and the engagement portion maintains the state in which the movable member biases the movable member toward the closed position. When the insertion of the flat conductor is brought to a position allowing the flat conductor to be inserted, and the insertion of the flat conductor to the predetermined position is completed, the movable member returns to the closed position by the urging force from the engaging portion, and the flat conductor The locked portion is locked with the locking portion, and the flat conductor is prevented from being pulled out backward, and the movable portion is Is in the open position, the locked state of the locking portion with respect to the locked portion is released, and the return movement of the movable member to the closed position is restricted by the urging force from the engaging portion. The flat conductor is allowed to be pulled out rearward.

In the present invention, the corresponding engaging portion of the movable member receives a biasing force toward the closed position from the engaging portion when the movable member is on the closed position side in the process of switching the movable member, When the movable member is on the open position side, the urging force toward the open position is received from the engagement portion. Therefore, when the movable member is once brought to the open position when the flat conductor is extracted, the return movement of the movable member to the closed position is restricted by the urging force from the engagement portion. As a result, in the process of extracting the flat conductor, the operator does not need to hold down the movable member in order to maintain the movable member in the open position as in the prior art, so the movable member is moved to the open position. After that, a series of operations of extracting the flat conductor can be easily performed. Moreover, in this invention, even if sufficient space for performing extraction operation with both hands is not ensured around the electrical connector for flat conductors, extraction operation can be performed with only one hand.

  In the present invention, the engaging portion provided on the housing or the attachment member is formed on an elastic arm portion that is inclined rearward and elastically displaceable in the front-rear direction, and biases the corresponding engaging portion of the movable member. The first engagement surface that engages with the first corresponding engagement surface of the corresponding engagement portion when the movable member is in the closed position, and the correspondence when the movable member is in the open position A second engagement surface that engages with the second corresponding engagement surface of the engagement portion may be formed.

  In the present invention, the attachment member is a metal fitting attached to the housing, and the metal fitting is attached to the housing at a position outside the terminal arrangement range in the terminal arrangement direction, and an engaging portion is formed on the metal fitting. May be. By forming the engaging portion on the metal fitting in this way, the strength of the engaging portion itself can be increased, so that the engaging portion is less likely to be damaged, and the corresponding engaging portion and thus the movable member is in the open position. It is possible to positively bias toward the closed position.

  In the present invention, the attachment member is a metal fitting that extends in the terminal arrangement direction and is attached to the housing, and the metal fitting is formed with an engaging portion at a position outside the terminal arrangement range in the terminal arrangement direction, and the terminal in the terminal arrangement direction. A cover plate portion covering the terminal arrangement range may be formed in a range including the arrangement range. By forming the engaging portion on the metal fitting, the engaging portion is not easily damaged as described above, and the corresponding engaging portion and thus the movable member can be reliably urged toward the open position or the closed position. Moreover, a shielding effect can be acquired by forming the cover part which covers this terminal arrangement | sequence range in the range containing the terminal arrangement | sequence range in a terminal arrangement | sequence direction.

  As described above, according to the present invention, once the movable member is brought to the open position when the flat conductor is extracted, the return movement of the movable member to the closed position is restricted by the urging force from the engagement portion. Therefore, in the process of extracting the flat conductor, it is not necessary for the operator to hold down the movable member in order to maintain the movable member in the open position as in the prior art. Therefore, a series of operations of extracting the flat conductor after moving the movable member to the open position can be easily performed. Moreover, even if a sufficient space for performing the extraction work with both hands is not secured around the electrical connector for a flat conductor, the extraction work can be performed with only one hand.

  In the present embodiment, the rear surface of the portion located below the bent portion 41B-3 is a lower surface as a first engagement surface that engages with the upper corresponding engagement surface 35A (first corresponding engagement surface) of the movable member 30. It is formed as a side engagement surface 41B-1 (see FIG. 3C). Further, the rear surface of the portion located above the bent portion 41B-3 is an upper engagement as a second engagement surface that engages with the lower corresponding engagement surface 35B (second corresponding engagement surface) of the movable member 30. It is formed as a surface 41B-2 (see also FIG. 6C). The lower engagement surface 41B-1 urges the movable member 30 toward the closed position by engaging with the upper corresponding engagement surface 35A (see FIG. 3C), and the upper engagement surface 41B-2 The movable member 30 is biased toward the open position by engaging with the lower corresponding engagement surface 35B (see FIG. 6C).

  As shown in FIG. 2, the lower held portion 41 </ b> C is located on the inner side in the terminal arrangement direction with respect to the elastic piece 41 </ b> A and cuts a part of the bottom plate portion 41 upward at a position near the front end of the bottom plate portion 41. It is shaped like a strip that is raised. The lower held portion 41C is formed by bending a belt-like piece extending rearward in a crank shape upward and rearward, and downward toward a free end side portion extending rearward. A protruding press-fit protrusion 41C-1 is formed by pressing. As shown in FIG. 3B, the lower held portion 41C is press-fitted from the front into the lower shell holding hole 12A of the housing 10 and is held by the lower shell holding hole 12A.

  As shown in FIG. 2, the upper plate portion 42 is press-held by the upper shell holding hole 13 </ b> B at a position corresponding to each upper shell holding hole 13 </ b> B of the housing 10 in the terminal arrangement direction. The portion 42A is formed by cutting and raising the rear end portion of the upper plate portion 42. The upper held portion 42A is formed by bending a belt-like piece extending rearward in a crank shape downward and rearward, and projects downward in a free end portion extending rearward. The press-fitting protrusion to be formed is formed by press working. The upper held portion 42A is pressed into the upper shell holding hole 13B of the housing 10 from the front and is held.

  As shown in FIG. 2, the side plate portion 44 is formed as a concave portion in which a side supported portion 44 </ b> A for attaching the shell 40 to the housing 10 is opened rearward in the rear half portion of the side plate portion 44. . The side held portion 44A is formed with a press-fit protrusion 44A-1 protruding upward at the lower edge thereof. As shown in FIGS. 1A and 1B, the side held portion 44A receives the side shell holding projection 14A of the housing 10 from the rear, and the press-fit projection 44A-1 holds the side shell. It is press-fitted and held by biting into the lower surface of the protrusion 14A.

  Further, the side plate portion 44 is bent inwardly in the terminal arrangement direction at the upper edge thereof, and the plate portion having a plate surface perpendicular to the vertical direction prevents the movable member 30 from being inadvertently detached from the housing 10. It is formed as a restricting portion 44B for this purpose. The restricting portion 44B is positioned so as to close the opening of the outer support concave portion 14B that accommodates the rotating shaft portion 33 of the movable member 30 from above with the shell 40 being attached to the housing 10, and is thus rotated. By restricting the upward movement of the shaft portion 33, the movable member 30 is prevented from being unintentionally detached from the housing 10.

  The fixing portion 45 is located at substantially the same height as the bottom plate portion 41, and is fixed by soldering to a corresponding portion of a circuit board (not shown). The fixing portion 45 is formed with a fixing hole portion 45A penetrating in the plate thickness direction so that the molten portion flows into the fixing hole portion 45A, so that the fixing portion 45 is more securely fixed to the corresponding portion. It has become.

  The connector 1 having such a configuration is assembled in the following manner. First, the terminal 20 is press-fitted and attached to the terminal accommodating portion 17 of the housing 10 from the rear. Further, the rotating shaft portion 33 of the movable member 30 is accommodated from above in the outer support concave portion 14B of the housing 10, and the movable member 30 is attached to the housing. As a result, the rotation shaft portion 33 is rotatably supported by the outer support concave portion 14B, and at the same time, the rotation supported portion 34 of the movable member 30 can also be rotated to the inner support concave portion 16A of the housing 10. (See FIG. 3C). Either the terminal 20 mounting step or the movable member 30 mounting step described above may be performed first, or may be performed simultaneously.

  Next, the lower held portion 41C, the upper held portion 42A, and the side held portion 44A of the shell 40 are replaced with the lower shell holding hole portion 12A, the upper shell holding hole portion 13B, and the side shell holding projection of the housing 10. The shell 40 is attached to the housing 10 by press-fitting each part 14A from the front. As a result of the shell 40 being attached to the housing 10, the restricting portion 44 </ b> B of the shell 40 is positioned so as to close the opening of the outer support recess 14 </ b> B of the housing 10 from above, so that the movable member 30 from the housing 10 is not prepared. Slipping out is prevented.

  Further, when the shell 40 is attached to the housing 10, the bottom wall of the housing 10 is within a range in which the bottom plate portion 41, the upper plate portion 42 and the front plate portion 43 of the shell 40 include the terminal arrangement range in the terminal arrangement direction. 12. A good shielding effect can be obtained by covering the upper wall 13 and the front wall 15 from below, above and from the front.

  Next, the connection operation between the connector 1 and the flat conductor C will be described with reference to FIGS. First, the connection part 25 of the terminal 20 of the connector 1 is soldered to the corresponding circuit part of the circuit board, and the fixing part 45 of the shell 40 is soldered and fixed to the corresponding part of the circuit board.

  Next, the movable member 30 is brought to the closed position (see FIGS. 3A to 3C), and the flat conductor C is disposed behind the connector 1 along the mounting surface of the circuit board (not shown). It is located to extend to. Next, the flat conductor C is inserted forward into the receiving portion 11 of the connector 1. In the process of inserting the flat conductor C into the receiving portion 11, the flat conductor C enters between the lower arm portion 21 and the upper arm portion 22 of the terminal 20 and is pressed from above by the pressing portion 22 </ b> A of the upper arm portion 22. As a result, first, as shown in FIG. 4A, the rear elastic arm portion 21C comes into contact with the rear contact portion 21C-1 of the rear elastic arm portion 21C of the lower arm portion 21 with contact pressure from above. Is elastically displaced downward. When the flat conductor C is further inserted, the flat conductor C comes into contact with the front contact portion 21B-1 of the front elastic arm portion 21B with contact pressure from above, and elastically moves the front elastic arm portion 21B downward. Displace.

  Further, the front end of the ear portion C2 located near the both ends of the flat conductor C abuts on the guide surface 36B of the locking portion 36 of the movable member 30 to rotate the movable member 30 toward the open position. The movable member 30 is brought to a position where the insertion of the flat conductor C is allowed. At this time, in the movable member 30 rotated toward the open position, the guide surface 36B of the locking portion 36 is in contact with the upper surface of the ear portion C2 of the flat conductor C, as seen in FIG. At that time, the rotation angle becomes maximum.

  On the other hand, as shown in FIG. 4C, the movable member 30 presses the engaging portion 41B of the shell 40 with the corner portion 35C of the corresponding engaging portion 35 to elastically displace the elastic piece 41A backward. As shown in FIG. 4C, the corner portion 35C of the corresponding engaging portion 35 presses the lower engaging surface 41B-1 of the engaging portion 41B as described above. This is a state in which the moving angle is maximized. Therefore, in the process of inserting the flat conductor C, the movable member 30 does not further rotate toward the open position side, and the corner portion 35C does not get over the bent portion 41B-3 of the engaging portion 41B. That is, the state in which the upper engagement surface 41B-2 of the engagement portion 41B is engaged with the lower corresponding engagement surface 35B of the corresponding engagement portion 35, that is, the state in which the movable member 30 is biased toward the open position (see FIG. 6 (C)). Therefore, in the process of inserting the flat conductor C, the state in which the lower engagement surface 41B-1 urges the movable member 30 toward the closed position is always maintained.

  When the flat conductor C is further inserted forward, as shown in FIGS. 5A to 5C, the front end of the flat conductor C comes into contact with the rear surface of the front wall 15 to reach the insertion completion position. Brought about. As shown in FIG. 5A, in the state where the flat conductor C is completely inserted, the elastic displacement states of the front elastic arm portion 21B and the rear elastic arm portion 21C are maintained, and the circuit on the lower surface of the flat conductor C is maintained. The front contact portion 21 </ b> B- 1 and the rear contact portion 21 </ b> C- 1 are in contact with each other with contact pressure and are electrically connected, and the connection operation of the flat conductor C is completed.

  When the flat conductor C is brought to the insertion completion position, as shown in FIG. 5B, the ear C2 of the flat conductor C passes through the position of the locking portion 36 and the locking portion 36 is reached. Is brought forward than. Therefore, when the movable member 30 receives the urging force from the engaging portion 41B of the shell 40 and returns to the closed position, the locking portion 36 has the flat conductor C as shown in FIG. It rushes into the cutout C1 from above. As a result, the engaged portion C2A of the flat conductor C is positioned so as to be engageable with the engaging surface 36A of the engaging portion 36, so that the flat conductor C is prevented from being pulled out rearward.

  When the movable member 30 is returned to the closed position, the lower engaging surface 41B-1 of the engaging portion 41B is attached to the upper corresponding engaging surface 35A of the corresponding engaging portion 35 as seen in FIG. Since the contact surface engages with the force, the movable member 30 is always maintained in the closed position by the force from the lower engagement surface 41B-1. Therefore, if the connector 1 and the flat conductor C are connected to each other, an excessive pulling output directed toward the rear acts on the flat conductor C, so that the movable member 30 is slightly lifted toward the open position. Even then, the movable member 30 is pushed back to the closed position by the urging force from the lower engagement surface 41B-1, so that the flat conductor C does not come out carelessly.

  Next, the operation of extracting the flat conductor C from the connector 1 will be described with reference to FIGS. First, in the connected state with the flat conductor C as seen in FIGS. 5A to 5C, the finger is hooked on the release operation portion 31A of the movable member 30 of the connector 1, and the above-described engagement is performed. The movable member 30 is rotated toward the open position against the urging force toward the closed position from the joint portion 41B. At this time, the locking portion 36 moves upward, that is, in a direction to escape from the cutout portion C1 of the flat conductor C.

  In the process in which the movable member 30 rotates toward the open position, the corner portion 35C of the corresponding engagement portion 35 of the movable member 30 elastically displaces the elastic piece 41A of the shell 40 toward the front. Until the corner portion 35C reaches the position of the bent portion 41B-3 of the engaging portion 41B, the lower engaging surface 41B-1 of the engaging portion 41B biases the movable member 30 toward the closed position. To do. Further, the movable member 30 is further rotated so that the corner portion 35C gets over the position of the bent portion 41B-3 of the engaging portion 41B, and the corner portion 35C becomes the upper engaging surface 41B-2 of the engaging portion 41B. The elastic piece 41A returns to the direction in which the elastic displacement amount decreases (rearward), and the engaging portion 41B biases the movable member 30 toward the open position with the upper engaging surface 41B-2. When the movable member 30 is switched to the open position in this way, the upper engaging surface 41B-2 of the engaging portion 41B is engaged with the lower corresponding engaging portion 35 as seen in FIG. The surface 35B is brought into contact with and engaged with the urging force. As a result, the return movement of the movable member 30 toward the closed position is restricted by the urging force from the upper engagement surface 41B-2, and the movable member 30 is maintained in the open position.

  When the movable member 30 is switched to the open position, as shown in FIG. 6 (B), the locking portion 36 completely escapes from the cutout portion C1 of the flat conductor C, and the flat conductor C The locked state with the locked portion C2A is released. At this time, as shown in FIG. 6A, the contact state having the contact pressure between the circuit portion on the lower surface of the flat conductor C and the contact portions 21B-1 and 21C-1 of the terminal 20 is maintained. It has been done. In this way, by pulling the flat conductor C backward while the movable member 30 is maintained in the open position, the flat conductor C is extracted from the connector 1 without difficulty, and the extraction operation is completed. .

  In the present embodiment, the engaging portion 41B of the shell 40 is engaged when the bent portion 41B-3 of the engaging portion 41B is above the corner portion 35C of the corresponding engaging portion 35 of the movable member 30. The lower engagement surface 41B-1 of the portion 41B engages with the upper corresponding engagement surface 35A of the corresponding engagement portion 35 to urge the movable member 30 toward the closed position, and the engagement portion 41B is bent. When the portion 41B-3 is below the corner portion 35C of the corresponding engaging portion 35, the upper engaging surface 41B-2 of the engaging portion 41B is the lower corresponding engaging surface 35B of the corresponding engaging portion 35. And the movable member 30 is urged toward the open position. Therefore, when the movable member 30 in the closed position is once switched to the open position when the flat conductor C is pulled out, the movable member 30 is maintained in the open position by the urging force from the engaging portion 41B. The

  Therefore, since it is not necessary for the operator to hold down the movable member 30 in order to maintain the movable member in the open position as in the prior art, in the present invention, in the process of extracting the flat conductor C, one hand is used. After bringing the movable member 30 to the open position, the one hand can be released from the movable member 30, and the flat conductor C can be grasped and pulled out by the one hand. That is, a series of operations of extracting the flat conductor C after moving the movable member 30 to the open position can be easily performed with only one hand. Moreover, in this embodiment, even if sufficient space for performing the extraction operation with both hands is not secured around the connector 1, the extraction operation can be performed with only one hand.

  In the present embodiment, since the engaging portion 41B for urging the movable member 30 to the closed position or the open position is formed on the shell 40 that is a metal fitting, the strength of the engaging portion 41B itself is increased. Can do. Therefore, the engaging portion 41B is less likely to be damaged, and the corresponding engaging portion 35 and thus the movable member 30 can be reliably urged toward the closed position or the open position. In addition, when sufficient intensity | strength of an engaging part can be ensured, you may form this engaging part in a part of housing. In this case, for example, the engaging portion can be formed as an elastically displaceable elastic piece standing from the bottom wall 12 of the housing 10.

  The present invention is not limited to the above-described embodiments, and can be implemented in various modifications as described below.

  In this embodiment, the engaging portions 41B of the elastic pieces 41 provided on the shell 40 are not only during the switching movement of the movable member 30, but also after the switching movement, that is, after the movable member 30 reaches the closed position or the open position. In this case, the movable member 30 is urged. Alternatively, the movable member 30 may be urged only during the switching movement. Specifically, after the moving movement of the movable member 30, the elastic piece 41 is in a free state and does not bias the movable member 30, and the engaging portion 41B is pressed by the corresponding engaging portion 35 in the process of switching movement. Only when elastically displaced, the engaging portion 41B biases the movable member 30 to bring the movable member 30 to the closed position or the open position. As a result of the biasing by the engaging portion 41B, the movable member 30 is maintained in the closed position or the open position.

  In this embodiment, the boundary portion separating the upper corresponding engagement surface 35A and the lower corresponding engagement surface 35B of the corresponding engagement portion 35 of the movable member 30 is the ridge line of the corner portion 35C. The boundary portion may be, for example, a convex curved surface or a flat surface. That is, it is sufficient that the upper corresponding engagement surface and the lower corresponding engagement surface have a positional relationship such that an intersection line is formed on a line extending in the terminal arrangement direction. In this case, when the engaging portion is above the intersecting line, it engages with the upper corresponding engaging surface to urge the movable member toward the closed position, and when the engaging portion is below the intersecting line. The movable member is urged toward the open position by engaging with the lower corresponding engagement surface.

  In the present embodiment, the elastically displaceable engaging portion 41B provided on the shell 40 urges the corresponding engaging portion 35 provided on the movable member 30 and not elastically displaced. A corresponding engaging portion that can be displaced may be provided on the movable member, and an engaging portion that is not elastically displaced may be provided on the shell so that the corresponding engaging portion biases the engaging portion. In this case, the movable member is maintained in the closed position or the open position by the reaction force that the corresponding engaging portion biases the engaging portion and receives from the engaging portion. In the present embodiment, one of the engaging portion and the corresponding engaging portion is elastically displaceable. Alternatively, both may be elastically displaceable.

  In the present embodiment, the shell 40 has the bottom plate portion 41, the upper plate portion 42, and the front plate portion 43, and covers and shields the arrangement range of the terminals 20 from below, from above, and from the front. When it is sufficient to obtain the effect, it is not essential to provide all of the bottom plate portion 41, the upper plate portion 42, and the front plate portion 43 in the terminal arrangement range. In addition, when the shielding effect is not particularly required, a metal fitting is attached to the housing 10 at a position outside the terminal arrangement range in the terminal arrangement direction without engaging the metal fitting at a position corresponding to the terminal arrangement range, and is engaged with the metal fitting. It is good also as forming a part.

  In the present embodiment, the engaging portion 36 of the movable member 30, the corresponding engaging portion 35, and the engaging portion 41B of the shell 40 are provided on both ends of the connector 1 in the terminal arrangement direction. In the case where a plurality of terminal arrangement ranges are formed, a locking portion, a corresponding engagement portion, and a position between the terminal arrangement ranges adjacent to each other along with or instead of the positions on both ends of the connector, An engaging part can also be provided. That is, the locking part, the corresponding engaging part, and the engaging part may be provided at a position outside the terminal arrangement range. In addition, when a latching | locking part is provided in the position between terminal arrangement | sequence ranges, the to-be-latched part of a flat conductor is a hole which penetrates in the thickness direction of a flat conductor in the position corresponding to the said latching | locking part, for example Formed as.

  Further, it is not essential that the engaging portion and the corresponding engaging portion of the movable member are provided corresponding to each other. Therefore, for example, the number of locking portions and the number of corresponding engaging portions may be different.

  In the present embodiment, the flat conductor C is connected to the connector 1 by inserting the flat conductor C while the movable member 30 is in the closed position, but instead, the movable member 30 is opened. It is also possible to connect the flat conductor C to the connector 1 by inserting the flat conductor C in the position and then bringing the movable member 30 to the closed position.
