Description

  The present invention relates to a lever type connector.

  The lever-type connector described in Patent Document 1 moves between a standby position and a detection position with respect to a lever body that can be fitted to a mating connector, a lever that is rotatably attached to the connector body, and the lever. And a detection member that can be assembled. The lever is formed in a gate shape as a whole from a lever operation part and a pair of arm parts protruding from both ends of the lever operation part. The detection member is also formed in a gate shape as a whole from the displacement operation part and a pair of legs protruding from both ends of the displacement operation part. Both arm portions are provided with engagement windows penetrating from the inner surface to the outer surface, and both leg portions are provided with lock portions at positions corresponding to the engagement windows.

  Here, the detection member is assembled to the inside of the lever in a retaining state by fitting both lock portions into the engagement window from the inner surface side of both arm portions. In the process in which the lever is rotated from the mating start position (initial state) to the mating position, the mating connector engaged with both arm portions is pulled toward the connector main body, so that the mating of both connectors proceeds. When the lever reaches the mating position, both connectors are held in the regular mating state. Also, in the lever turning process, the lock part is kept at the standby position on one side in the length direction of the engagement window, and when the lever reaches the fitting position, the lock part is on the other side in the length direction of the engagement window. It is possible to move to the detection position. Thus, when the detection member moves to the detection position, it is possible to know that both connectors are in the normal fitting state.

JP 2003-257546 A

  In the case of the conventional lever-type connector, the detection member has a relatively large gate shape, so that the handleability is poor and it is difficult to meet the demand for downsizing. On the other hand, if the detection member has a key shape and the entire detection member is fitted into the engagement window of the arm portion, the request for downsizing can be met. However, in such a configuration, there is a possibility that a region where the whole detection member is allowed to be inserted / removed opens in the engagement window of the arm portion, and the detection member may come out through the region. On the other hand, when a structure for restricting the withdrawal of the detection member is provided, there is a problem in that the structure is complicated and is not preferable.

  This invention is completed based on the above situations, Comprising: It aims at providing the lever-type connector which can avoid the enlargement and complication of a detection member.

  The present invention provides a connector main body that can be mated with a mating connector, and is rotatably mounted between a mating start position and a mating position with respect to the connector main body. The mating connector and the connector body are properly connected by rotating from the mating start position to the mating position in a state where the arm unit is engaged with the mating connector. It is supposed to reach a fitted state, and has a form that penetrates from the inner surface to the outer surface of the arm part, and has an assembly allowance region on one side in the length direction intersecting the penetration direction, and a separation restriction region on the other side. A lever provided with a receiving portion, and assembled to the assembly allowable region of the receiving portion from the inner surface side of the arm portion; in the assembled state, the lever is allowed to come out to the inner surface side; In the process of rotating from the mating start position to the fitting position, the receiving portion is located in the separation regulating area and is separated from the lever and displaced to the assembly allowable area, and the lever is fitted. Displacement to the assembly allowable region is allowed when reaching the position, and the assembly allowable region further includes a key-shaped detection member that faces the side surface of the connector main body and is restricted from coming out to the inner surface side. However, it has characteristics.

  Since the detection member has a key shape, an increase in size of the detection member can be avoided. On the other hand, if it is a key-shaped detection member, the detection member may come out of the inner surface side of the assembly allowable region of the receiving portion. However, according to the above configuration, when the detection member is positioned in the separation restriction region of the receiving portion in the process in which the lever is rotated from the fitting start position to the fitting position, the detection member is prevented from being detached from the lever. In the state where the lever reaches the fitting position and is displaced to the assembly allowable region, the detection member is opposed to the side surface of the connector main body and is prevented from coming out to the inner surface side. It can be prevented without it.

In the lever-type connector of an Example, it is a top view which shows the state by which the lever was kept in the fitting start position with respect to the connector main body, and the detection member was hold | maintained in the detachment | leave control area | region of a receiving part. Furthermore, it is a top view which shows the state which the lever reached to the fitting position with respect to the connector main body. Furthermore, it is a top view which shows the state which the detection member displaced to the assembly | attachment permission area | region of a receiving part. It is sectional drawing which cut | disconnected the state by which the lever was kept at the fitting start position with respect to the connector main body, and the detection member was hold | maintained at the detachment | leave control area of a receiving part in the position corresponding to a detection member. Furthermore, it is sectional drawing which cut | disconnected the state which reached the fitting position with respect to the connector main body in the position corresponding to a detection member. Furthermore, it is sectional drawing which cut | disconnected the state which the detection member displaced to the assembly | attachment tolerance area | region of the receiving part in the position corresponding to a detection member. FIG. 4 is a sectional view taken along line AA in FIG. 3. It is a rear view of the main body of a connector. It is a top view of a lever. It is a side view of a lever. It is a top view of an electric wire cover. It is a top view of a detection member. It is a front view of a detection member. It is a side view of a detection member.

Hereinafter, preferred embodiments of the present invention will be shown.
The lever is formed in a gate shape from a pair of the arm portions and a connecting portion that connects both arm portions, and the detection member is assembled only in one of the receiving portions of the both arm portions. Since it is not necessary to assemble a plurality of detection members on the lever, it is possible to reduce the assembling work burden. Moreover, if the receiving part is provided in both of the arm parts, any receiving part can be appropriately selected according to the layout situation of the installation place.

  On the side surface of the connector main body, the detection member slides in the process of rotating the lever from the fitting start position to the fitting position, so that the detection member is displaced to the assembly allowable region. An arcuate slide receiving portion for regulating is provided, and the detection member that reaches the assembly allowable region at the fitting position is disposed so as to be able to contact an edge of the slide receiving portion, and the lever of the lever Return rotation to the fitting start position is restricted. Since the slide receiving part of the connector body has both the function of restricting the displacement of the detection member to the assembly allowable region and the function of restricting the return rotation of the lever to the fitting start position, both functions are provided in different parts. Compared with the case where it is provided, the configuration can be further simplified.

As shown in FIG. 4, each locking portion 25 slides and comes into contact with a locking receiving portion 26 provided at the rear end of the main housing 11, so that the wire cover 12 is prevented from coming out from the main housing 11. It has become so.

  As shown in FIG. 11, a pair of arcuate slide receiving portions 27 are provided on the outer surface of the both side plate portions 22 (only one side plate portion 22 is shown in FIG. 11). The sliding receiving portion 27 is formed in a rib shape that extends in the width direction and curves so that the central portion in the extending direction is located on the back plate portion 21 side. The rear surface of the slide receiving portion 27 is configured as a slide receiving surface 28 arranged along a concentric circle with the support shaft 16 as the center in a state where the electric wire cover 12 is attached to the main housing 11. As shown in FIG. 4, a sliding portion 62 described later of the detection member 60 is slidable on the sliding receiving surface 28.

  The lever 40 is made of a synthetic resin and has a portal plate shape as shown in FIG. 10, a connecting portion 41 extending in the vertical direction, and a pair of arm portions 42 projecting in parallel from both ends of the connecting portion 41. have. As shown in FIG. 9, a bearing hole 43 penetrates the arm portion 42, and a cam groove 44 penetrates near the bearing hole 43. The bearing hole 43 is configured to open in a substantially circular cross section, and the cam groove 44 is configured to extend in a curved shape and open to the outer peripheral edge of the arm portion 42. The entrance of the cam groove 44 is closed at the outer peripheral edge of the arm portion 42 by a bridge portion 45 on the outside.

  Here, the lever 40 is mounted on the connector main body 10 so as to straddle from the rear, and the both support shafts 16 of the connector main body 10 are fitted into the bearing holes 43 of the both arm portions 42, thereby being supported by the connector main body 10. (See FIG. 1). The lever 40 is rotatable about the support shaft 16 fitted in the bearing hole 43 to the fitting start position shown in FIGS. 1 and 4 and the fitting position shown in FIGS. 2, 3 and 5. It is said that. At the fitting start position, the entrance of the cam groove 44 is arranged facing forward. In this state, when the connector body 10 is shallowly fitted with the mating connector 90, the cam follower 91 (see FIG. 1) of the mating connector 90 is fitted into the entrance of the cam groove 44. Next, when the lever 40 is rotated toward the fitting position, the cam follower 91 slides on the groove surface of the cam groove 44 to exert a cam action, and the mating connector 90 is pulled toward the connector body 10. Thereafter, as shown in FIG. 2, when the lever 40 reaches the fitting position, the cam follower 91 moves to the back end side of the cam groove 44, and both the connectors are in the normal fitting state. When the two connectors are properly fitted in this way, the terminal fitting 80 attached to the connector body 10 is normally connected to a mating terminal fitting (not shown) of the mating connector 90.

  A lever lock portion 46 is provided at the connecting portion 41 of the lever 40. As shown in FIGS. 2 and 5, when the lever 40 reaches the fitting position, the lever lock portion 46 is elastically locked to the lever lock receiving portion 24, whereby the lever 40 is restricted from rotating to the connector body 10. It is kept in the state that was done.

  Further, as shown in FIG. 9, receiving portions 47 are provided on both arm portions 42 of the lever 40 (only one arm portion 42 is shown in FIG. 9). The receiving portion 47 is configured to penetrate the arm portion 42 from the inner surface to the outer surface in the plate thickness direction, and to extend in the length direction intersecting the plate thickness direction. Specifically, the receiving portion 47 has a rectangular main hole 48 extending substantially along a direction connecting the bearing hole 43, the coupling portion 41, and the bearing hole 43, and one end portion of the main hole 48 on the bearing hole 43 side. A first sub-hole 49 that is recessed to expand the hole width to the left and right sides, and a second sub-hole 51 that is recessed to increase the hole width to the left and right sides at a position near the connecting portion 41 of the main hole 48. The main hole 48 has a third sub-hole 52 that is recessed so that the hole width of the portion on the outer side in the plate thickness direction of the arm portion 42 is expanded to the left and right sides at a position close to the first sub-hole 49. In this case, one side in the length direction of the receiving portion 47 (the lower side of the receiving portion 47 in FIG. 9) that is the side having the first sub-hole 49 is configured as an assembly allowable region 53 that allows the detection member 60 to be assembled. The other side in the length direction of the receiving portion 47 (the upper side of the receiving portion 47 in FIG. 9) that is the side having the second sub-hole 51 is configured as a separation regulating region 54 that regulates the separation of the detection member 60 from the lever 40. Is done.

  The detection member 60 is made of synthetic resin and has a key shape. The detection member 60 is inserted into the receiving portion 47 of one of the arm portions 42 from the inner surface side of the arm portion 42, and is shown in FIGS. Thus, it can be moved between the assembly allowable region 53 and the separation restricting region 54 in the inserted state. Specifically, as shown in FIGS. 12 to 14, the detection member 60 includes a substantially rectangular block-shaped detection main body 61 and one end surface in the length direction on the short side of the detection main body 61 (the detection main body 61 in FIG. 12). A pair of first outer retaining portions 63 and a pair of first outer retaining portions 63 provided on both side surfaces of the long side of the detection main body 61 (upper and lower surfaces of the detection main body in FIG. 12). A second outer retaining portion 64 and a plurality of inner retaining portions 65 are provided.

  As shown in FIG. 7, the detection main body 61 has a size that can be inserted into the main hole 48 of the receiving portion 47 and a thickness that is equal to or greater than the plate thickness of the arm portion 42, and is inserted into the main hole 48. It has the part which protrudes in both the inside and outside of 42. As shown in FIGS. 12 and 13, the outer surface of the detection body 61 is a concave curved operation surface 66 that can be touched by a fingertip when the detection member 60 is operated. A plurality of anti-slip ridges 67 are provided on the operation surface 66.

  As shown in FIGS. 13 and 14, the sliding portion 62 is from the inner region (the side located inside the arm portion 42 when assembled to the lever 40) on one end surface in the length direction on the short side of the detection main body 61. As shown in FIG. 12, it has a substantially bowl-shaped wide portion 68 at the tip. As shown in FIG. 7, when the detection member 60 is assembled to the lever 40 and is in the assembly allowable region 53, a sliding portion 62 is inserted between the arm portion 42 and the connector main body 10. .

  As shown in FIG. 12, the pair of first outer retaining portions 63 is close to one end surface in the length direction of the outer region (the side located outside the arm portion 42 when assembled) on both side surfaces on the long side of the detection main body 61. It is the form which protrudes in the shape of a wing at the position. Further, the pair of second outer retaining portions 64 is configured to project in a wing shape at a position near the other end surface in the length direction of the outer region on both side surfaces on the long side of the detection main body 61. As shown in FIG. 3, when the detection member 60 is assembled to the lever 40, the first outer retaining portion 63 and the second outer retaining portion 64 are respectively the first sub hole 49 and the second sub hole 51 of the arm portion 42. And projecting outside the arm portion 42. The first outer retaining portion 63 is larger than the second outer retaining portion 64 and has a size that can be fitted into the first sub hole 49, and the second outer retaining portion 64 is fitted into the second sub hole 51. It is configured with a size that can be matched.

  As shown in FIGS. 12 and 13, the plurality of inner retaining portions 65 are configured to project in a wing shape from three positions spaced in the length direction of the inner region on both side surfaces on the long side of the detection main body 61. ing. Among these, as shown in FIG. 12, the inner retaining portions 65 positioned at both ends in the length direction are arranged at positions overlapping the first outer retaining portion 63 and the second outer retaining portion 64 in the length direction. Then, as shown in FIG. 4, when the detection member 60 is assembled to the lever 40, each inner retaining portion 65 is disposed so as to protrude inside the arm portion 42.

The above is the structure of the lever-type connector of the present embodiment. Next, the operation of the lever-type connector will be described.
First, the detection member 60 is assembled to one of the receiving portions 47 of the both arm portions 42 from the inner surface side of the arm portion 42. In this case, the detection member 60 may be assembled to the receiving portion 47 on the side where the operator can easily operate the detection member 60. The detection member 60 is configured such that both the first outer retaining portions 63 are passed through the first sub holes 49 and the second outer retaining portions 64 are passed through the second sub holes 51. It is inserted into the assembly allowable area 53. In a state in which the detection member 60 is assembled in the assembly allowable region 53 before being assembled to the lever 40, both the first outer retaining portions 63 and the second outer retaining portions 64 are both the first sub holes 49 and the second second subsidiary portions, respectively. Since it can be inserted into and out of the arm portion 42 through the hole 51, the detection member 60 is allowed to come out from the inner surface side of the arm portion 42. However, in the assembly allowable region 53, the detection members 60 come out from the outer surface side of the arm portion 42 by arranging each inner retaining portion 65 so as to be able to contact the opening edge of the receiving portion 47 on the inner surface of the arm portion 42. Is prevented.

  Subsequently, the detection member 60 is slid toward the connecting portion 41 in the receiving portion 47 to reach the separation regulating region 54 (see FIG. 1). When the detection member 60 reaches the separation regulating region 54, the first outer retaining portions 63 and the second outer retaining portions 64 are disposed so as to be able to contact the opening edge of the receiving portion 47 on the outer surface of the arm portion 42, and Each inner retaining portion 65 is maintained in a state where it can be brought into contact with the opening edge of the receiving portion 47 on the inner surface of the arm portion 42. For this reason, the detection member 60 is prevented from slipping out from any of the inner and outer surfaces of the arm portion 42. Further, in the separation regulating region 54, the other end surface in the length direction of the detection member 60 (the upper end surface of the detection member 60 in FIG. 1) is the other end edge in the length direction of the receiving portion 47 (the upper side of the receiving portion 47 in FIG. 1). Further movement operation of the detection member 60 is restricted in contact with the edge. Furthermore, in the detachment restricting region 54, the outer portions of the first outer retaining portions 63 are fitted in the third sub holes 52 and are maintained in a substantially positioned state.

  Next, as shown in FIGS. 1 and 4, the bearing holes 43 of both arm portions 42 of the lever 40 are fitted to the both support shafts 16 of the connector main body 10, and the lever 40 is held at the fitting start position. Then, the tip of the sliding portion 62 of the detection member 60 comes into contact with the sliding receiving surface 28 of the sliding receiving portion 27, thereby restricting the detection member 60 from moving inside the receiving portion 47 to the assembly allowable region 53 side. Is done.

  Subsequently, the mating connector 90 is shallowly fitted to the connector main body 10, and in this state, the lever 40 is rotated in the clockwise direction in the drawing toward the fitting position while grasping the connecting portion 41. Then, as described above, the cam action is exerted between the lever 40 and the mating connector 90, and the two connectors are brought into the normal fitting state. While the lever 40 is rotated from the fitting start position to the fitting position, the tip of the sliding portion 62 slides on the sliding receiving surface 28 of the sliding receiving portion 27, so that the detection member 60 is separated from the separation regulating region. 54, and the detection member 60 is prevented from falling to the assembly allowable region 53 side. Further, when the detection member 60 passes through the top of the arc of the sliding receiving portion 27 in the process in which the lever 40 is rotated from the fitting start position to the fitting position, substantially the entire detection main body 61 is completely covered by the wire cover 12. In this state, the inner surface side is temporarily exposed. However, when the detection member 60 is in the separation regulating region 54, as shown in FIGS. 1 and 4, the tip of the sliding portion 62 comes into contact with the sliding receiving portion 27, and the first outer retaining portion 63 and the second outer retaining portion 63 are in contact with each other. Since the retaining portion 64 is disposed so as to be able to contact the outer surface of the arm portion 42 and each inner retaining portion 65 is disposed so as to be able to contact the inner surface of the arm portion 42, the detection member 60 is detached from the arm portion 42. Is prevented.

  When the lever 40 reaches the fitting position, as shown in FIGS. 2 and 5, the sliding portion 62 is detached from the end portion of the sliding receiving portion 27 and loses support from the sliding receiving portion 27, and the detection member 60. However, it will be in the state which can move the inside of the receiving part 47 to the assembly | attachment permission area | region 53. FIG. Therefore, the detection member 60 is pushed into the assembly allowable region 53. When the detection member 60 reaches the assembly allowable region 53, as shown in FIG. 7, the sliding portion 62 is sandwiched between the inner surface of the arm portion 42 and the side plate portion 22 of the wire cover 12. Further, when the detection member 60 reaches the assembly allowable region 53, the sliding portion 62 is disposed so as to be able to contact the end portion of the sliding receiving portion 27. For this reason, even if the lever 40 is rotated toward the fitting start position in a state where the detection member 60 is retained in the assembly allowable region 53, the sliding portion 62 contacts the end portion of the sliding receiving portion 27. This prevents the lever 40 from turning in the return direction. Furthermore, in the assembly allowable region 53, as shown in FIG. 6, the inner retaining portion 65 abuts against the slide receiving portion 27, so that further pressing of the detection member 60 is prevented.

  Unlike the case where the lever 40 is in a single state, when the detection member 60 reaches the assembly allowable region 53 as described above, the inner surface of the detection member 60 is the outer surface (connector body) of the side plate portion 22 of the wire cover 12 as shown in FIG. 10 side surfaces). For this reason, the detection member 60 is prevented from coming out from the inner surface side of the arm portion 42. In addition, the detection member 60 is prevented from being pulled out to the outer surface side of the arm portion 42 by the respective inner retaining portions 65. Therefore, the detection member 60 that has reached the assembly allowable region 53 in a state where the lever 40 is attached to the connector main body 10 is prevented from coming out from any of the inner and outer surfaces of the arm portion 42.

  If the turning operation of the lever 40 is stopped before reaching the fitting position due to the carelessness of the operator, the sliding portion 62 of the detection member 60 is placed on the sliding receiving surface 28 of the sliding receiving portion 27. Since it is located, the detection member 60 cannot be moved to the assembly allowable region 53. Therefore, it is possible to know that both connectors are in a properly fitted state when the detection member 60 can move in the receiving portion 47 from the separation regulating region 54 to the assembly allowable region 53 side.

  As described above, according to the present embodiment, since the detection member 60 has a key shape as a whole, an increase in size of the detection member 60 can be avoided. Further, in the process in which the lever 40 is rotated from the fitting start position to the fitting position, the detection member 60 is positioned in the separation regulating region 54 of the receiving portion 47, so that the separation of the detection member 60 from the lever 40 is regulated. The Further, in a state where the lever 40 reaches the fitting position and moves to the assembly allowable region 53, the detection member 60 faces the side surface of the connector main body and the withdrawal of the arm portion 42 to the inner surface side is restricted. For this reason, it is not necessary to provide the connector main body 10 or the lever 40 with a dedicated structure for preventing the detection member 60 from slipping out to the inner surface side of the arm portion 42 when the detection member 60 reaches the assembly allowable region 53. It is possible to prevent the configuration from becoming complicated.

  Moreover, since the detection member 60 is assembled | attached only to any one receiving part 47 of both the arm parts 42, the work burden of an assembly | attachment can be reduced. Furthermore, since the receiving portion 47 on the side where the detection member 60 can be easily moved can be appropriately selected according to the layout situation of the installation location, the operability is excellent.
