Description

  The present invention relates to a board electrical connector (hereinafter referred to as “board connector”) attached to a circuit board, and a cable electrical connector (hereinafter referred to as “cable connector”) having the board connector and a terminal with a cable connected to the board connector. Connector assembly).

  Patent Document 1 discloses a connector assembly in which a cable connector having a terminal with cable is fitted and connected to the board connector in a fitting direction perpendicular to the circuit board in a state where the cable extends in parallel with the surface of the circuit board. Is disclosed.

  In the cable connector of Patent Document 1, a pair of elastic arm portions are provided on the side wall surface of the housing so as to extend in a fitting direction to a board connector as a mating connector. The elastic arm portion has a base portion forming a connecting portion with the housing that is thin and narrow with respect to the other portion, and can be elastically deformed by the thin base portion. The elastic arm portion is integrally provided with a protruding lock portion that protrudes in the direction in which the cable extends, that is, in the front-rear direction and has a lower surface formed as a tapered surface.

  On the other hand, the board connector has a notch opening formed in the side wall portion of the housing for receiving the elastic arm portion of the cable connector when the connector is fitted, and the notch opening in the front-rear direction. The edge portion is provided with a hook-shaped locking portion that protrudes inward of the connector.

  At the time of connector fitting, when the elastic arm portion of the cable connector enters the notch opening portion of the board connector, the taper surface of the lock portion of the elastic arm portion comes into contact with the locking portion of the board connector. The elastic arm portion receives a reaction force from the locking portion on the taper surface of the lock portion, and is elastically bent and deformed inward of the connector, thereby allowing further insertion of the connector. When the lock part passes the position of the locking part, the elastic arm part is released from the elastic deformation and returns to the original shape in the free state, and the locking part is locked to the upper end surface of the locking part to prevent the connector from coming off. So-called locking is performed.

Further, when the cable connector is pulled out from the board connector, a pressing force is applied to the operation portion so that the operation portion formed as a flat surface at the tips of the two elastic arm portions is grasped with a finger. The elastic arm portion receives this pressing force and is elastically deformed toward the inside of the connector, and when the displacement amount becomes equal to the displacement amount for locking, that is, the thickness of the lock portion, the lock portion is the board connector. Thus, the cable connector can be pulled out.
JP2007-149615

  From the viewpoint of space saving in the electrical equipment in which the connector is used, the connector is often required to be miniaturized in the connector insertion / removal direction, so-called low profile. In order to ensure operability, it is necessary to form the area of the operation portion of the elastic arm portion, that is, the area of the portion pressed by the finger when the connector is pulled out to a certain extent, this is the connector insertion / removal direction, that is, the connector height direction However, since a certain size is required, there is a limit to satisfy the above-mentioned demand for a low profile. Further, since the lock portion needs to be moved in the height direction of the connector for locking, the movement distance of the lock portion must be ensured in the height direction, which is disadvantageous for reducing the height.

  When the cable connector is fitted to the board connector attached to the circuit board, the cable connector is pushed into the board connector in the connector fitting direction. In the connector assembly of Patent Document 1, as a pressing force for this operation, in addition to the force required for connector fitting (terminal-to-terminal connection and housing-to-housing), the cable connector lock portion and the board The force required for locking (locking) with the locking portion of the connector is required. Therefore, in addition to the force required for fitting the connector, the force required to push the cable connector in the connector fitting direction, that is, the direction perpendicular to the circuit board, is required by the amount required for locking. This results in an undesirable result because this large force is transmitted to the circuit board via the board connector.

  In view of such circumstances, the present invention can sufficiently satisfy the demand for a low profile connector, and a connector for a board and a connector for a cable that can reduce the force for pushing the cable connector when the connector is fitted. It is an object to provide a connector assembly having the same.

<First invention>
An electrical connector for a board according to the present invention is an electrical connector for a board to be attached to a circuit board, and the cable electrical connector as a mating connector having a terminal with a cable is connected to the cable in a state where the cable extends rearward. The fitting connection is possible in the fitting direction perpendicular to the outgoing direction.

  Such an electrical connector for a board includes a moving member that is attached to the housing so as to be movable in the front-rear direction, and the movable member is a fitting allowable position that allows the electrical connector for a cable to be fitted to the electrical connector for a board. And the separation preventing position for preventing the cable electrical connector from being separated, and the moving member is located at the separation preventing position with respect to the locked portion provided on the housing of the cable electrical connector. And a locking portion that is locked in the direction of detachment of the cable electrical connector (hereinafter referred to as “connector detachment direction”) to prevent the cable electrical connector from being detached.

  In such a board electrical connector, the movement of the moving member is performed in the front-rear direction, that is, in a direction parallel to the cable extension direction. This is done by moving the member back and forth with a finger. When operating the moving member, it is not necessary to grip the side surface of the moving member with a finger. Therefore, it is not necessary to increase the height dimension of the moving member in order to ensure the area of the portion where the finger contacts the moving member. Further, the moving direction of the lock portion of the moving member is the front-rear direction, not the connector insertion / extraction direction. Therefore, in the present invention, it is not necessary to secure the movement distance of the lock portion in the connector insertion / extraction direction. Further, since a force having a component in a direction perpendicular to the surface of the circuit board is not applied to the moving member for locking, the force for locking is not transmitted to the circuit board.

  In the board connector according to the present invention, the connectors are locked in the connector detaching direction by moving the moving member after the connectors are fitted. Accordingly, when the cable electrical connector is pushed into the board electrical connector attached to the circuit board, the cable connector is not locked in the connector detaching direction. That is, it is not necessary to apply a locking force when pushing the cable electrical connector.

  One of the moving member and the housing has a locking portion for maintaining the moving member in the separation preventing position, and the other has a locked portion. The locking member and the locked portion are separated from the moving member. It is preferable to lock each other in the front-rear direction in the state of being in the blocking position. With such a configuration, the moving member is disengagement prevented by the locking of the locking portion and the locked portion in the front-rear direction, that is, the locking portion of the moving member and the locked portion of the cable electrical connector are the connectors. It is maintained at a position where it is locked in the disengagement direction. Therefore, the locked state of the lock portion and the locked portion is stabilized, and the cable electrical connector is reliably prevented from being detached.

  It is preferable that the lock portion is configured to be engaged with the locked portion of the cable electrical connector at a position corresponding to the contact portion of the terminal in the front-rear direction at the separation preventing position. According to such a configuration, the lock part and the locked part in the front-rear direction are locked at a position corresponding to the contact position between the contact part of the terminal of the board electrical connector and the contact part of the terminal of the cable electrical connector. . Therefore, prevention of detachment of the cable electrical connector is focused at the contact position in the front-rear direction, and even if an external force acts on the connector in the connector fitting state, a good contact state between the terminals is maintained.

  It is preferable that the lock portion is configured to be engaged with the locked portion of the cable electrical connector at a position near the rear of the housing at the separation preventing position. According to such a configuration, since the lock portion and the locked portion are locked at a position closer to the rear of the connector, the cable extending rearward is carelessly moved in the direction in which the cable electrical connector is detached (the direction opposite to the fitting direction). Even when this force has a component in the connector detachment direction, the force for pulling the cable is received by the locking portion of the moving member at a position closer to the rear of the housing and closer to the rear. It does not act on the part in front of the position, that is, on the entire housing of the cable electrical connector. As a result, the disconnection of the cable electrical connector is reliably prevented.

  The moving member preferably covers a connection portion between the terminal of the board electrical connector and the circuit board at the separation preventing position. By covering the connecting portion with the moving member at the separation preventing position, it is possible to prevent dust and dirt from adhering to the connecting portion, and as a result, it is possible to avoid a decrease in electrical performance of the connector. Moreover, protection from the external force with respect to the said connection part is also achieved.

  The moving member may be provided at a rear position of the housing. A cable extends to a rear position of the housing, and a rear region on the circuit board corresponding to the cable at the rear position is a portion where other electronic components cannot be disposed and is originally a dead space. By providing a moving member in a region corresponding to this cable, a wide front region can be secured, so that the front region can be effectively used, for example, by mounting other electronic components in the front region of the housing.

<Second invention>
A connector assembly according to the present invention includes the above-described board electrical connector and a cable electrical connector fitted and connected to the board electrical connector, and the cable electrical connector is not connected to the board electrical connector. At the time of complete fitting, the movement of the moving member to the detachment preventing position is prevented by the contact of the locking portion of the moving member with the locked portion of the cable electrical connector in the front-rear direction. The movement of the moving member to the detachment prevention position is allowed without the lock portion coming into contact with the locked portion in the front-rear direction.

  According to such a configuration, when the moving member is moved toward the separation preventing position when the connector is in an incompletely engaged state, the locking portion of the moving member is in contact with the locked portion of the cable electrical connector. The movement of the moving member is prevented in contact. Accordingly, it can be recognized that the board electrical connector and the cable electrical connector are in an incompletely fitted state.

<Third invention>
A connector assembly according to the present invention includes the above-described board electrical connector and a cable electrical connector that is fitted and connected to the board electrical connector, and includes a movable member lock portion and a cable electrical connector lock portion. At least one of these has a guiding slope that facilitates movement of the moving member to the separation preventing position.

  According to such a structure, when the board electrical connector and the cable electrical connector are in an incompletely fitted state, when the movable member is moved toward the separation preventing position, the movable member is locked. Even if the portion abuts against the locked portion of the cable electrical connector and cannot move linearly to the release prevention position, the lock portion is guided and guided toward the release prevention position by the guiding slope. The moving member reaches the separation preventing position. In addition, in the process from the time when the lock part comes into contact with the locked part in the front-rear direction to the time when the lock part reaches the detachment prevention position, the lock part moves together with the guide guide in the direction in which the cable electrical connector is inserted. Press the part. When the moving member reaches the separation preventing position, the connectors are in a completely fitted state. That is, by moving the moving member toward the separation preventing position, the connectors that have been incompletely fitted can be automatically brought into the fully fitted state.

  In the present invention, it is not necessary to increase the dimension of the moving member in the connector height direction in order to secure the area of the portion where the finger contacts the moving member, and the moving member moves in the connector height direction. In order to ensure the area of the portion to be pressed with a finger in the elastic arm portion having a lock portion as in the prior art, the size of the elastic arm portion in the connector insertion / extraction direction is required to some extent, The height of the connector can be reduced as compared with a conventional electrical connector in which the connector insertion / extraction direction, that is, the height of the connector is required by the moving distance of the lock portion.

  Further, in the present invention, when the cable electrical connector is pushed into the circuit board electrical cable connector attached to the circuit board to be fitted, the connectors are not locked in the connector release direction, and the lock in the same direction is not performed. Compared with the conventional connector assembly that is locked when the connector is fitted, the force for pushing in the cable electrical connector can be reduced by the amount that does not require a force for the purpose. Therefore, the force transmitted to the circuit board when the connector is fitted based on the pushing force is reduced, and as a result, deformation or breakage of the circuit board can be prevented.

Further, the terminal 30 has a mounted portion 33 that extends upward from the base portion 31 at an intermediate position in the front-rear direction and has a protruding end at the tip. The tip of the attached portion 33 bites into the inner surface of the terminal holding groove 21 </ b> A of the housing 20, whereby the terminal 30 is fixed to the housing 20.

  In the terminal 30, a concave portion between the contact portion 32 and the attached portion 33 in the front-rear direction is formed as a receiving portion 34 that receives a front end portion of a terminal of a cable connector 60 described later when the connector is fitted. The terminal 30 extends downward to the same level as the circuit board (not shown) in the connector height direction at a position closer to the front, that is, the right position in FIG. 3A and is parallel to the circuit board (paper surface). The portion parallel to the circuit board is formed as a connection portion 35. The terminal 30 is electrically connected to the corresponding circuit unit by soldering the connection unit 35 to the corresponding circuit unit of the circuit board.

  Further, the connecting portion 35 extends forward from the front end surface of the front wall portion 21, and when the moving member 40 is in the fitting allowable position, as is often seen in FIG. A connection portion with a corresponding circuit (not shown) can be viewed from above. Thereby, the solder connection state between the terminal 30 and the corresponding circuit can be recognized.

  As shown in FIG. 1, the moving member 40 includes two arm portions 41 extending in the front-rear direction at substantially the same distance between the side wall portions 22 of the housing 20, and the front end of the arm portion 41 extending in the connector width direction. It has the connection part 42 which connects parts. The arm portion 41 has such a shape that an upper plate portion 41A and a lower plate portion 41B having plate surfaces perpendicular to the connector height direction are arranged at intervals in the connector height direction. The portion 41A and the lower plate portion 41B are connected by a locked portion 41C at a position closer to the connector outer side of the rear end portion of the arm portion 41 (see FIGS. 1 and 4B).

  As can be seen well in FIG. 2, the upper plate portion 41 </ b> A of each arm portion 41 has an edge portion on the inner side of the connector in the connector width direction positioned more inside the connector than the side wall portion 22 of the housing 20. The edge portion of the upper plate portion 41A has a planar shape having a step portion at an intermediate position in the front-rear direction, the front side portion extends inward of the connector from the rear side portion, and the front side portion is the first side portion. One lock portion 41A-1 and the rear side portion are formed as a second lock portion 41A-2.

  In the present embodiment, the first lock portion 41A-1 is formed in a portion corresponding to the contact portion 32 of the terminal 30 in the front-rear direction when the moving member 40 is in the separation preventing position where it has moved backward. Further, the second lock portion 41A-2 is formed at a portion located closer to the rear of the housing 20 when the moving member 40 is in the separation preventing position (see FIGS. 5A and 5B). As will be described later, the first lock part 41A-1 and the second lock part 41A-2 are locked in the connector preventing direction (upward direction in FIG. 5A) at the disconnection preventing position. Thus, the cable connector 60 is prevented from being detached. Hereinafter, for convenience of explanation, the first lock portion 41A-1 and the second lock portion 41A-2 are collectively referred to as a “lock portion”.

  4B, the locked portion 41C is located on the outer side of the connector with respect to the side wall portion 22 of the housing 20, and the side surface on the connector inner side of the locked portion 41C is The side surface of the side wall portion 22 on the outer side of the connector, that is, the surface on which the first locking portion 22A and the second locking portion 22B are provided substantially coincides in the connector width direction.

  As shown in the right half of FIG. 4B, when the moving member 40 is in the fitting allowable position, the locked portion 41C of the moving member is connected to the first locking portion 22A of the housing 20. It is located between the second locking portion 22B. The front end surface of the locked portion 41C faces the rear end surface of the first locking portion 22A in the front-rear direction, and it is assumed that a force that moves the moving member 40 forward acts on the moving member 40. In addition, the front end surface of the locked portion 41C and the rear end surface of the first locking portion 22A come into contact with each other. That is, since the locked portion 41C and the first locking portion 22A are locked with each other when the locked portion 41C is moved in the forward direction, the moving member 40 is prevented from being pulled forward.

  Further, as shown in the right half of FIG. 4B, when the moving member 40 is in the fitting allowable position, the front end surface is formed as a tapered surface behind the locked portion 41C. The second locking portion 22B is located. That is, when the moving member 40 moves rearward toward the separation preventing position, the locked portion 41C has to get over the second locking portion 22B.

  Further, as shown in the right half of FIG. 5B, when the moving member 40 moves to the separation preventing position, the rear end surface is formed as a tapered surface in front of the locked portion 41C. Since the two locking portions 22B are positioned, when the moving member 40 moves forward toward the fitting allowable position, the locked portion 41C has to get over the second locking portion 22B. .

  As shown in FIG. 1, the cable connector 60 has a substantially rectangular parallelepiped housing 70 and a terminal 80 (see FIG. 3A) to which the cable C is attached, that is, a terminal with a cable. On the rear surface of the housing 70, a plurality of terminal holes 71 are formed in a line in the connector width direction. The housing 70 protrudes toward the outside of the connector at a position closer to the rear of both side surfaces extending in the front-rear direction, and a first locked portion 70A formed by thinning the front ends of both side edges. A second locked portion 70B is provided (see FIG. 1).

  70 A of said 1st to-be-locked parts are located corresponding to the contact part 85 mentioned later of the terminal 80 of the connector 60 for cables in the front-back direction (refer FIG. 3 (A) and FIG. 3 (B) together) ). As will be described later, when the moving member 40 is in the separation preventing position, the first lock portion 41A-1 and the first locked portion 70A, the second lock portion 41A-2 and the second locked portion 70B are The positions in the directions match each other. Hereinafter, for convenience of description, the first locked portion 70A and the second locked portion 70B are collectively referred to as “locked portions”.

  As seen in FIG. 3A, the terminal hole 71 penetrates in the front-rear direction, and further opens downward in the front part. The lower opening 72 of the terminal hole 71 has a terminal receiving part 72A on the front end side and a locking hole 72B on the rear side. The terminal receiving portion 72A is an opening for receiving the contact portion 32 of the terminal 30 of the board connector 10 from below, and the locking hole 72B is locked with the locking portion of the terminal to prevent the cable-attached terminal from coming off. A space for performing The terminal 80 will be described later.

  The terminal with cable is obtained by crimping the terminal 80 to the cable C. As shown in FIG. 3A, the terminal 80 extends downward from a back plate-like base portion 81 extending in the front-rear direction, and is integrally formed with the base portion 81. The crimping portion 82, the crimping portion 83, and the locking portion 84 are formed. The contact portion 85 is provided in a pair of pieces in order from the rear portion to the front. The caulking portion 82 is caulked by the covering of the cable C, whereby the terminal 80 is held by the cable C. The crimping portion 83 is crimped to the core wire C1 of the cable C or soldered together therewith and is electrically connected to the core wire C1. The locking portion 84 forms a leg piece, and the lower end of the locking portion 84 enters the locking hole 72B of the housing 70 and is locked in the front-rear direction with the end edge of the locking hole 72B. The contact portion 85 is curved so that the tips of both leg pieces are wound inwardly, and the contact portion 32 of the terminal 30 of the board connector 10 is received between the curved portions so as to be elastically sandwiched and brought into contact therewith. It has become. Such a terminal 80 itself is publicly known, and further detailed explanation is omitted.

  Next, how to use the thus configured board connector 10 and cable connector 60 will be described.

  First, as shown in FIGS. 1 to 3A, 3B, and 3C, the moving member 40 of the board connector 10 mounted on the circuit board (not shown) before the connector is fitted. 4 is inserted into the receiving recess 24 of the board connector 10 from above, and the connector shown in FIGS. 4A and 4B is fitted. Bring to the state. When the cable connector 60 is fitted, the contact portion 32 of the terminal 30 of the board connector 10 and the contact portion 85 of the terminal 80 of the cable connector 60 come into contact with each other, and the two connectors are electrically connected.

  As shown in FIG. 4B, when the moving member 40 is in the fitting allowable position, the locking parts 41A-1 and 41A-2 of the moving member and the locked parts 70A and 70B of the cable connector are It is not in the position to lock. Further, as described above, the solder connection portion between the connection portion 35 of the terminal 30 and the corresponding circuit portion of the circuit board is visible from above.

  Next, the moving member 40 is moved backward to perform locking to prevent the cable connector 60 from being detached. When an operation force is applied to the moving member 40 by the operator applying a backward operation force with a finger, the moving member 40 is engaged with the second locking portion of the housing 20 by the locked portion 41C of the moving member 40. It moves over the portion 22B and moves backward, and is brought to the separation preventing position as shown in FIGS. 5 (A), (B) and FIGS. 6 (A), (B), (C).

  In the present embodiment, if the cable connector 60 is in an incompletely fitted state with respect to the board connector 10, that is, the cable connector 60 has not reached the complete fitting position downward, the moving member 40 is used. Is moved rearward toward the release prevention position, the rear surfaces of the lock portions 41A-1 and 41A-2 of the moving member 40 come into contact with the front surfaces of the locked portions 70A and 70B of the cable connector 60 and are released. Retraction of the moving member 40 to the blocking position is blocked. In this way, by preventing the moving member 40 from moving backward, it can be recognized that the board connector 10 and the cable connector 60 are in an incompletely fitted state. When recognizing that it is in an incompletely fitted state, the cable connector 60 may be pushed further downward into the board connector 10 so as to be in a completely fitted state, and then the moving member 40 may be retracted again. When the cable connector 60 is completely fitted to the board connector 10, the movement member 40 moves to the separation preventing position without the rear end surface of the lock portion coming into contact with the front end surface of the locked portion. Is acceptable.

  When the moving member 40 is brought to the separation preventing position, the first lock portion 41A-1 of the moving member 40 is positioned above the first locked portion 70A of the cable connector 60 and the second lock portion 41A-2 of the moving member 40. Is positioned above the second locked portion 70B of the cable connector 60, whereby the locking to the cable connector 60 is completed. That is, even if an inadvertent upward force acts on the cable connector 60, the first lock portion 41A-1 is locked with the first locked portion 70A in the connector release direction, and the second lock When the portion 41A-2 is engaged with the second locked portion 70B in the connector detaching direction, the detachment of the cable connector 60 is prevented.

  When the cable connector 60 is desired to be detached from the board connector 10, the moving member 40 is moved forward and returned, and the lock is released by bringing the moving member 40 to the original fitting allowable position. Thereafter, the cable connector 60 may be pulled upward from the board connector 10.

  In this embodiment, since the movement of the moving member 40 is performed in the front-rear direction, that is, in a direction parallel to the circuit board, the operation of the moving member 40 for locking and releasing the cable connector 60 is performed by moving the moving member 40. This is done by moving the finger back and forth. At this time, it is not necessary to pick the side surface of the moving member 40 with a finger, and the moving member 40 may be simply pushed. Therefore, it is not necessary to increase the height dimension of the moving member 40 in order to secure the area of the portion where the finger abuts the moving member 40. Further, the moving direction of the locking portion of the moving member 40 is the front-rear direction, not the connector insertion / extraction direction (connector height direction). Therefore, in this embodiment, it is not necessary to ensure the movement distance of the lock portion in the connector insertion / extraction direction.

  Therefore, in this embodiment, in order to secure the area of the portion to be picked and pressed by the finger in the elastic arm portion having the lock portion as in the prior art, the size of the elastic arm portion in the connector insertion / extraction direction is required to some extent, In addition, the height of the connector can be reduced as compared with an electrical connector that requires the height of the connector by the moving distance of the lock portion.

  In the present embodiment, the connectors are locked in the fitting direction by moving the moving member 40 after the connectors are fitted. That is, when the cable connector 60 is pushed in a direction perpendicular to the circuit board in order to fit the cable connector 60 to the board connector 10 attached to the circuit board, locking in the fitting direction is not performed. Therefore, it is not necessary to apply a locking force when pushing the cable electrical connector. As a result, as compared with the conventional connector assembly that is locked when the connector is fitted, the force for pushing in the cable connector 60 can be reduced by the amount that is not locked. Therefore, the force transmitted to the circuit board when the connector is fitted based on the pushing force is reduced, and deformation or breakage of the circuit board can be prevented.

  In a state where the moving member 40 is brought to the separation preventing position, as shown in the left half of FIGS. 5A and 5B and FIG. 6A, the terminals of the board connector 10 A connection portion between the circuit board 30 and a corresponding circuit portion (not shown) of the circuit board is covered with a connecting portion 42 of the moving member 40 located above the connection portion. Thus, by covering the connecting portion with the connecting portion 42, it is possible to prevent dust and dirt from adhering to the connecting portion, and as a result, it is possible to avoid a decrease in electrical performance of the connector. Moreover, protection from the external force with respect to the said connection part is also achieved.

  In the present embodiment, the first lock portion 41A-1 and the first locked portion 70A include the contact portion 32 of the terminal 30 of the board connector 10 and the contact portion 85 of the terminal 80 of the cable connector 60 in the front-rear direction. It is locked at a position corresponding to the contact position. Accordingly, prevention of detachment of the cable connector 60 is focused on the contact position in the front-rear direction, and a good contact state between the terminals is maintained.

  In the present embodiment, the second lock part 41A-2 and the second locked part 70B are configured such that the cable C extends rearward from the housing 70 in a position closer to the rear of the housings 20, 70, that is, in the front-rear direction. Lock in the vicinity of the position. As a result, when the cable C is inadvertently pulled in the direction of detachment of the cable connector 60, the pulling force of the cable C is a position closer to the rear of the housings 20, 70, that is, the second lock portion 41A. -2 and the second locked portion 70B are received by the second lock portion 41A-2. Therefore, the component of the pulling force of the cable C in the detachment direction does not act on the portion in front of the locking position, that is, the entire housing 70 of the cable connector 60. As a result, the detachment of the cable connector 60 is reliably prevented.

  In addition, the locking part and the locked part can be formed in a wide range in the front-rear direction by forming the locking part and the locked part large in the front-rear direction, or by forming a plurality of locking parts and locked parts over the entire front-rear direction. The part can be locked, and the detachment of the cable connector 60 is further effectively prevented.

  In the present embodiment, when a force in the forward direction, that is, the direction in which the lock is released, is applied to the moving member 40 in the separation preventing position, the locked portion 41C of the moving member 40 and the second locking of the housing 20 The portion 22B is engaged with each other. Therefore, even if a forward force acts on the moving member 40 inadvertently, the moving member 40 does not easily move forward, and the moving member 40 is maintained at the separation preventing position. . That is, the state in which the first lock portion 41A-1 and the first locked portion 70A, and the second lock portion 41A-2 and the second locked portion 70B are locked with each other in the connector detaching direction is maintained. Therefore, the locked state between the lock portion and the locked portion is stabilized, and the cable connector 60 is reliably prevented from being detached.

  In the present embodiment, in the board connector, the housing is provided with the second locking portion, and the moving member is provided with the locked portion. A second locking portion may be provided on the moving member. Even with such a configuration, it is possible to maintain the moving member in the separation preventing position.

  In the present embodiment, as shown in FIG. 6B, the lower surface of the first lock portion 41A-1 and the upper surface of the first locked portion 70A are in the same position in the connector height direction and are in surface contact with each other. . Further, as shown in FIG. 6C, the lower surface of the second lock portion 41A-2 and the upper surface of the second locked portion 70B are in the same position in the connector height direction and are in surface contact with each other.

  As described above, in this embodiment, when the moving member 40 is in the separation preventing position, the lock portion and the locked portion that are engaged with each other come into contact with each other, but instead, between the lock portion and the locked portion. A gap may be formed in the connector insertion / extraction direction. Even in such a configuration, when an inadvertent upward force is applied to the cable connector 60, the locked portion of the cable connector 60 moved upward is locked with the lock portion of the moving member 40. As a result, further movement of the cable connector 60 is restricted, so that the detachment of the cable connector 60 can be reliably prevented.

  In the present embodiment, when the cable connector 60 is incompletely fitted to the board connector 10, the moving member 40 is locked when the moving member 40 is moved backward toward the separation preventing position. Although the rear surfaces of the portions 41A-1 and 41A-2 are in contact with the front end surfaces of the locked portions 70A and 70B of the cable connector 60, the movement of the moving member 40 to the separation preventing position is prevented. As an alternative, at least one of the lock portions 41A-1 and 41A-2 and the locked portions 70A and 70B may be formed with a guiding slope that facilitates the movement of the moving member 40 to the separation preventing position.

  According to such a configuration, when the board connector 10 and the cable connector 60 are in an incompletely fitted state, when the operation of moving the moving member 40 toward the separation preventing position is performed, the lock portion 41A -1 and 41A-2 are in contact with the locked portions 70A and 70B and cannot move linearly to the separation preventing position as they are, the locking portions 41A-1 and 41A-2 are The moving member 40 reaches the separation prevention position by being guided and guided toward the separation prevention position. Further, in the process from the time when the lock portion contacts the locked portion in the front-rear direction to the time when the lock portion reaches the detachment prevention position, the lock portion together with the guide guide is inserted into the cable connector 60, that is, downward. The locked part is pressed. When the moving member 40 reaches the separation preventing position, the connectors are in a completely fitted state. That is, by moving the moving member 40 toward the separation preventing position, the connectors that have been incompletely fitted can be automatically brought into the fully fitted state.

  In the present embodiment, the moving member 40 is made of synthetic resin. However, as a modification, the moving member may be made of metal, and the entire or part of the surface of the synthetic resin moving member is a metal plate. It may be covered with. As a result, at the separation preventing position, the connecting portion between the terminal 30 of the board connector 10 and the corresponding circuit portion (not shown) of the circuit board is covered by a moving member made of metal or covered with a metal plate. A shielding effect can be obtained at the connecting portion.

  Further, in this modification, for example, an arbitrary terminal 30 of the plurality of terminals 30 of the board connector 10 is used as a ground terminal, and the surface of the moving member is in contact with the ground terminal when the moving member is in the separation preventing position. Then, it may be electrically connected. Further, for example, the front end of the fixing bracket 50 shown in the right half of FIG. 5B is extended forward and protruded from the fixing bracket holding portion 22C, and when the moving member is in the separation preventing position, The fixing metal 50 may have a ground function so that the end surface and the tip of the fixing metal 50 are in contact with each other and are electrically connected.

  In the present embodiment, the fitting direction of the board connector 10 and the cable connector 60 is a direction perpendicular to the circuit board. However, the fitting direction is not limited to this, and an angle with respect to the circuit board is provided. The connectors may be fitted together.

  Further, in this embodiment, after the connector fitting is completed and a stable contact state between the terminals is ensured, the moving member 40 is moved to the separation preventing position to lock the cable connector 60. Instead, a stable contact state between the terminals can be secured by moving the moving member to the separation preventing position. For example, a terminal having elasticity in the connector insertion / removal direction is provided in the board connector, and a terminal not having elasticity in the connector insertion / removal direction is provided in the cable connector, and the moving member is in the separation preventing position, and When the lock part is locked in the connector release direction, the terminal of the cable connector may press the terminal of the board connector downward to ensure a stable contact state between the terminals.

  Instead of the above-described terminals, a terminal that does not have elasticity in the connector insertion / removal direction may be provided in the board connector, and a terminal that has elasticity in the same direction may be provided in the cable connector. It goes without saying that the terminals having the same may be provided on both the board connector and the cable connector.

<Second embodiment>
This embodiment is different from the first embodiment in which the moving member is provided at the rear position on the cable extension side of the housing in the board connector. In the present embodiment, the difference from the first embodiment will be mainly described.

  FIG. 7 is a perspective view showing a state of the connector assembly 101 in which the cable connector 160 is fitted to the board connector 110 according to the present embodiment, and FIG. 7A is a state in which the moving member is in the fitting allowable position. (B) shows the state in which the moving member is in the separation preventing position, omitting the illustration of the cable extending rearward (leftward in the drawing).

  A moving member 140 is provided at a rear position of the housing 120 of the board connector 110 fixed to a circuit board (not shown), and the moving member 140 is arranged in the front-rear direction with respect to the housing 120, that is, on the circuit board. It is provided so as to be movable in a parallel direction. In the present embodiment, with respect to the moving member 140, the rear position is the fitting allowable position (see FIG. 7A), and the front position is the separation preventing position (see FIG. 7B).

  As shown in FIG. 7A, the housing 120 of the board connector 110 includes a front wall 121 that extends in the connector width direction and holds a plurality of terminals (not shown) arranged in the same direction. The wall portion 121 has a pair of side wall portions 122 extending rearward from both ends of the connector width direction. The side wall portion 122 has basically the same shape as the arm portion 41 of the moving member 40 in the first embodiment. That is, the side wall 122 has an upper plate portion 122A and a lower plate portion 122B that are located at intervals in the connector height direction and extend in parallel in the front-rear direction, and the upper plate portion 122A and the lower plate portion 122B at the rear end. And a locked portion 122C that is connected at a position outside the connector. Note that the upper plate portion 122A in the present embodiment is provided with the first lock portion 41A-1 and the second lock portion 41A-2 in that the lock portion is not provided. The configuration is different from the arm portion 41.

  The moving member 140 is connected to two arm portions 141 extending in the front-rear direction at substantially the same interval as between the side wall portions 122 of the housing 120, and connected to the rear end portion of each arm portion 141 in the connector width direction and the height direction. The rear wall 142 has a rectangular parallelepiped outer shape larger than the portion 141, and the bottom wall 143 connects the rear walls 142 in the connector width direction.

  The arm part 141 has the same shape as the side wall part 22 of the housing 20 in the first embodiment. That is, in the arm portion 141, the first locking portion 141A and the second locking portion 141B that are locked in the front-rear direction with the above-described locked portion 122C of the housing 120 protrude outwardly in the connector width direction. (See FIGS. 7A and 7B). The first locking portion 141A is formed in front of the second locking portion 141B. In the present embodiment, the first locking portion 141A and the second locking portion 141B of the moving member 140 and the locked portion 122C are locked in the first locking portion 22A of the housing 20 in the first embodiment and Since it is the same as the locking form of the 2nd latching | locking part 22B and the to-be-latched part 41C of the moving member 40, detailed description about the locking form of this embodiment is abbreviate | omitted. An angular lock portion 142A that protrudes inward of the connector and extends in the front-rear direction is provided at a position closer to the rear of the side surface on the inner side in the connector width direction of the rear wall portion 142 of the moving member 140.

  As shown in FIG. 7A, the cable connector 160 has a substantially rectangular parallelepiped housing 170 and a terminal with cable (not shown). The point that a plurality of terminal holes 171 are formed in a row in the connector width direction on the rear surface of the housing 170 is the same as in the first embodiment. In the present embodiment, recessed portions 172 that are recessed toward the inside of the connector and extend in the front-rear direction are formed at positions closer to the rear of both side surfaces of the housing 170. As will be described later, the locked portion 172 receives the lock portion 142A of the moving member 140 when the moving member 140 is in the forward position, that is, the separation preventing position.

  Next, how to use the board connector 110 and the cable connector 160 thus configured will be described.

  First, before the connector is fitted, when the moving member 140 of the board connector 110 mounted on the circuit board (not shown) is in the rear position, that is, in the fitting allowable position, the receiving recess of the board connector 110 is received. The cable connector 160 is inserted from above into the connector fitting state as shown in FIG. In the connector fitting state, a cable (not shown) extends rearward through the bottom wall portion 143 of the moving member 140.

  Next, the moving member 140 is moved forward to perform locking to prevent the cable connector 160 from being detached. That is, when the operator performs a moving operation by applying an operation force directed forward to the moving member 140 by pushing the rear surface of the rear wall 142 of the moving member 140 forward with a finger or the like, the movement is performed. The member 140 is brought to the disengagement prevention position as shown in FIG. 7 (B) by moving the second locking portion 141B of the moving member 140 over the locked portion 122C of the housing 120 and moving forward.

  When the moving member 140 moves forward, the front end portion of the lock portion 142A of the moving member 140 enters the locked portion 172 of the cable connector 160, as shown in FIG. 7B. As a result, the locking portion 142A and the locked portion 172 are locked in the connector detaching direction, and thereby the detachment of the cable connector 160 from the board connector 110 is prevented.

  In the connector fitting state, a cable extends to the rear position of the housing 120 of the board connector 110, and no other electronic component can be placed in the rear area on the circuit board corresponding to the cable at the rear position. It is a part and is essentially a dead space. In the present embodiment, since the moving member 140 is provided at the rear position of the housing 120, that is, the position where the cable extends, a wide front area of the housing 120 can be secured. The front area can be used effectively, for example, by mounting components.

  In this embodiment, as shown in FIGS. 7A and 7B, the lock portion 142A of the board connector 110 is provided at a position near the rear of the moving member 140, and the cable connector 160 is covered. The lock portion 172 is provided at a position near the rear of the housing 170. That is, the lock portion 142A and the locked portion 172 are locked at a position near the rear in the connector assembly 101, that is, near a position where the cable extends rearward from the housing 170.

  Therefore, when the moving member 140 is in the separation preventing position, when the cable is inadvertently pulled in the direction in which the cable connector 160 is detached, the force for pulling the cable is close to the rear of the moving member 140 and the housing 170. It is received by the lock portion 142A at the position, that is, the locking position between the lock portion 142A and the locked portion 172. Therefore, the component of the pulling force of the cable in the detaching direction does not act on the portion in front of the locking position, that is, the entire housing 170 of the cable connector 160. As a result, the detachment of the cable connector 160 is reliably prevented.

  Note that the various modifications described in the first embodiment can also be applied to this embodiment.

<Third embodiment>
In this embodiment, the locking portion and the locked portion in the connector detaching direction are locked over the entire area of the front end edge of the cable connector, and the locking portion and the locked portion are locked on the front end edge. This is different from the first embodiment which is partially made. The basic configuration of the board connector and the cable connector according to the present embodiment is the same as that of the first embodiment. Therefore, the same portions are denoted by the same reference numerals and the description thereof is omitted. The difference will be mainly described.

  8A and 8B are perspective views showing a state in which the board connector and the cable connector according to the present embodiment are fitted, in which FIG. 8A shows a state in which the moving member is in the fitting allowable position, and FIG. The state in the separation preventing position is shown with the illustration of the cable omitted. 8A and 8B are shown as views seen from the front side in order to facilitate understanding of the locking form.

  In the board connector 10 according to the present embodiment, the third lock portion 42A is formed such that the rear end edge extending in the connector width direction on the upper wall of the connecting portion 42 of the moving member 40 extends rearward substantially over the entire region in the same direction. have. Further, the arm portion 41 is, like the arm portion 41 in the first embodiment, a contact portion (not shown) of the terminal of the board connector 10 in the front-rear direction when the moving member 40 is in the rear position, that is, the separation preventing position. The first lock portion 41A-1 is formed at a position corresponding to the first position, and the second lock portion 41A-2 is formed extending inward in the connector width direction at a portion located closer to the rear of the housing 20.

  As shown in FIGS. 8A and 8B, a connection confirmation portion 42 </ b> B is formed in the lower portion of the connecting portion 42. The connecting confirmation portion 42 </ b> B opens downward and forms a recess that penetrates the connecting portion 42 in the front-rear direction. Yes. By looking into the connection confirmation part 42B from the front, the solder connection state between the terminal (not shown) of the board connector 10 located below the connection confirmation part 42B and the corresponding circuit part (not shown) of the circuit board Can be confirmed.

  The cable connector 60 is formed by opening a third locked portion 70 </ b> C as a hole portion extending in the same direction in the same direction as the connector width direction of the third lock portion 42 </ b> A in the front surface of the housing 70. Yes. The third locked portion 70C is formed at a position such that when the cable connector 60 is completely fitted to the board connector 10, the third locked portion 70C is located at the same position as the third lock portion 42A in the connector height direction. . 8A and 8B, the first locked portion (corresponding to the first locked portion 70A in FIG. 1) and the second locked portion 70B are not connected to the cable connector 60. When the connector 10 is completely fitted to the connector 10, it is formed at a position that is located below the lower surfaces of the first lock portion 41A-1 and the second lock portion 41A-2 in the connector insertion / extraction direction (connector height direction). Has been.

  Next, how to use the thus configured board connector 10 and cable connector 60 will be described.

  First, before the connector is fitted, the receiving concave portion of the board connector 10 in a state where the moving member 40 of the board connector 10 mounted on the circuit board (not shown) is in the forward position, that is, the fitting allowable position. The cable connector 60 is inserted from above into the connector fitting state shown in FIG.

  Next, the moving member 40 is moved backward to perform locking to prevent the cable connector 60 from being detached. That is, when the operator applies a backward operation force to the moving member 40 by pushing the front surface of the moving member 40 with a finger or the like, the moving member 40 moves backward. It moves to the separation preventing position as shown in FIG.

  When the moving member 40 moves rearward toward the separation preventing position, the third lock portion 42A of the moving member 40 has a third locked portion of the cable connector 60 as shown in FIG. 8B. Enter the part 70C. As a result, the third lock portion 42A and the third locked portion 70C are locked in the connector release direction. Moreover, 1st lock part 41A-1 is located above a 1st to-be-locked part (not shown) in the position corresponding to the contact position of the contact parts of a terminal in the front-back direction similarly to 1st embodiment. Then, it is locked with the first locked portion in the connector releasing direction. Similarly to the first embodiment, the second lock portion 41A-2 is located above the second locked portion 70B near the rear of the housings 20 and 70, and in the connector release direction. Locks to the lock portion 70B. In this way, the first lock part 41A-1 and the first locked part, the second lock part 41A-2 and the second locked part 70B, and the third lock part 42A and the third locked part 70C are detached. Each locking in the direction prevents the cable connector 60 from being detached from the board connector 10.

  In the present embodiment, in addition to the two locking positions in the first embodiment, that is, the positions corresponding to the contact positions of the terminals in the front-rear direction and the rear positions of the housings 20, 70, the connector width direction at the front edge of the housing 70 Since the locking is performed by the third lock portion 42A and the third locked portion 70C in the entire region, the effect of preventing the cable connector 60 from being detached is improved. In addition, as shown in FIG. 8B, the locking position between the third lock portion 42A and the third locked portion 70C is the first lock portion 41A-1 and the first locked portion in the front-rear direction. Close to the locking position with the part. Therefore, the locking of the third lock portion 42A and the third locked portion 70C also emphasizes the prevention of the cable connector 60 from being detached at the contact position between the terminals, and the good contact state between the terminals. Is more reliably maintained.

  Note that the various modifications described in the first embodiment can also be applied to this embodiment.

<Fourth embodiment>
In the present embodiment, the locked portion at the front edge of the cable connector is formed on the upper surface of the housing of the cable connector, and the locked portion is formed as a hole on the front surface of the cable connector. This is different from the third embodiment. The basic configuration of the board connector and the cable connector according to the present embodiment is the same as that of the third embodiment. Therefore, the same portions are denoted by the same reference numerals, and the description thereof is omitted. The difference will be mainly described.

The cable connector 60 is formed as a third locked portion 70 </ b> C ′ that engages with the third lock portion 42 </ b> A ′ in the entire region in the connector detaching direction of the front end edge of the upper surface of the housing 70. The third locked portion 70 </ b> C ′ is flush with the upper surface of the housing 70.

  Further, when the cable connector 60 is completely fitted to the board connector 10, the housing 70 has an upper surface of the housing 70 in the connector insertion / removal direction (connector height direction) and the lower surface of the third lock portion 42A ′. It is located at the same position or below the lower surface.

  According to the board connector 10 and the cable connector 60 configured as described above, when the moving member 40 moves rearward to the separation preventing position, the third lock portion 42A ′ of the moving member 40 is connected to the housing 70. It is located above the third locked portion 70C ′ that forms the same plane, and is engaged with the third locked portion 70C ′ in the connector release direction.

The locking of the cable connector 60 from the board connector 10 is prevented by the locking of the locked portion 70B, the third lock portion 42A ′, and the third locked portion 70C ′ in the connector releasing direction.

  Note that the various modifications described in the first embodiment can also be applied to this embodiment.

<Fifth embodiment>
In the present embodiment, with respect to the position of the moving member, the rear position is a fitting allowable position and the front position is a separation preventing position, and the front position is a fitting permission position and the rear position is a separation preventing position. It is different from the first embodiment. The basic configuration of the board connector and the cable connector according to the present embodiment is the same as that of the first embodiment. Therefore, the same portions are denoted by the same reference numerals and the description thereof is omitted. The difference will be mainly described.

  FIG. 10 is a perspective view showing a state before the board connector and the cable connector according to the present embodiment are fitted together. 11A and 11B are perspective views showing a state in which the board connector and the cable connector according to the present embodiment are fitted, in which FIG. 11A shows a state in which the moving member is in the fitting allowable position, and FIG. The state in the separation preventing position is shown with the illustration of the cable omitted.
