Description

  The present invention relates to a lever-type connector.

  The lever-type connector is obtained by attaching a lever for assisting fitting with a mating connector to a housing fitted with the mating connector. When fitting the lever-type connector to the mating connector, first the cam pin projecting from the mating connector is engaged with the cam groove of the lever with the lever in the standby position, and then the lever is rotated to the mating position. As a result, both the connectors are drawn together by the cam action of the cam pin and the cam groove, and are brought into a fitted state. As an example of such a lever-type connector, one described in Patent Document 1 below is known.

JP 2003-249304 A

The lever-type connector described in Patent Document 1 includes a lever, a terminal fitting, a sub-connector that accommodates the terminal fitting, and a holder that accommodates the lever and the plurality of sub-connectors. According to such a configuration, the lever-type connector can be assembled in such a procedure that the terminal fitting is first accommodated in the sub-connector and then the sub-connector in the state where the terminal fitting is accommodated is accommodated in the holder. Even if the lever is arranged to protrude rearward from the rear end surface of the holder in both the standby position and the mating position, the factor that hinders the housing operation when housing the terminal fitting in the sub-connector It is not supposed to be.
However, since this lever type connector requires a plurality of sub-connectors and a holder, there has been a problem that the number of parts is increased and the number of assembling steps is also increased.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to reduce the number of parts while improving the workability of accommodating the terminal fitting.

  The lever-type connector of the present invention has a terminal fitting and a cam groove for receiving a cam pin provided in the mating connector, and is rotated from a standby position allowing the cam pin to enter the cam groove to a fitting position. Accordingly, the lever includes a lever that pulls the mating connector into a mating state, a terminal accommodating portion that accommodates the terminal fitting, and a lever accommodating portion that accommodates the lever. A connector housing, the rear end surface of which is flush with the rear end surface of the lever at the fitting position, or the position protruding rearward from the rear end surface of the lever at the fitting position And a connector housing.

  According to the configuration described above, in order to fit the mating connector into the connector housing, first, the cam pin of the mating connector is inserted into the cam groove of the lever with the lever in the standby position. Then, when the lever is rotated from the standby position to the mating position, the mating connector is pulled in by the cam action of the cam pin and the cam groove to reach the mating state.

  On the other hand, when the terminal fitting is received in the terminal housing part of the connector housing, the lever housed in the lever housing part of the connector housing is set to the mating position so that the rear of the lever in the mating position is Since the rear end surface of the connector housing is flush with the end surface, or the rear end surface of the connector housing protrudes rearward, the lever prevents the terminal fitting from being accommodated in the terminal accommodating portion. Things are hard to happen. Thus, since it is possible to improve the workability of housing the terminal fittings without adopting a structure for housing the lever and the sub-connector in the holder as in the prior art, the number of parts and the number of assembly steps can be reduced. Can do.

The following configuration is preferable as an embodiment of the lever-type connector of the present invention.
(1) Although the lever protrudes rearward from the rear end surface of the connector housing in the standby position, the rear end surface is arranged at a position where the rear end surface is flush with the rear end surface of the connector housing in the fitting position. The lever is accommodated in the lever accommodating portion. In this manner, when the mating connector is fitted into the connector housing, when the lever is rotated from the standby position to the mating position, the lever projects from the rear end surface of the connector housing to the connector housing. It reaches a state of being flush with the rear end surface of the housing. Therefore, when the lever is rotated, if the lever protrudes rearward from the rear end surface of the connector housing, the lever has not reached the fitting position, and the fitting state has not been reached. The half-fitted state can be detected.

(2) The lever housing portion has an opposing wall portion that is arranged in an opposing manner with a space capable of housing the lever with respect to a side surface of the terminal housing portion, whereas the lever is A lever main body accommodated between the terminal accommodating portion and the opposing wall portion, and provided so as to protrude at least toward the opposing wall portion in the normal direction of the side surface of the terminal accommodating portion with respect to the lever main body. A rotation operation portion, and the lever is further rotated from the fitting position by abutting against the rotation operation portion of the lever at the fitting position on the opposing wall portion. An excessive rotation restricting recess for restricting movement is formed in a notch. In this case, the lever is provided with the rotation operation portion so as to protrude toward the opposing wall portion with respect to the normal direction of the side surface of the terminal housing portion with respect to the lever main body. In addition, the rotation operation portion can be easily rotated, which is suitable for reducing the size of the lever-type connector. Then, the counter wall is formed with a notch for the excessive rotation restricting concave portion that contacts the rotation operation portion when the lever is rotated to the fitting position, so that the lever is further rotated from the fitting position. Can be controlled. That is, excessive rotation from the fitting position of the lever can be regulated by using the rotation operation unit and the opposing wall unit that overlap each other in the normal direction of the side surface of the terminal accommodating unit. Compared with the case where a movement restricting structure is provided, the structure can be simplified and more useful in reducing the size.

(3) Whereas the lever housing portion has an opposing wall portion arranged in an opposing manner with a space capable of housing the lever with respect to a side surface of the terminal housing portion, A lever main body accommodated between the terminal accommodating portion and the opposing wall portion, and provided so as to protrude at least toward the opposing wall portion in the normal direction of the side surface of the terminal accommodating portion with respect to the lever main body. A rotation operation part, and the opposite wall part comes into contact with the rotation operation part of the lever at the standby position so that the engagement position side is separated from the standby position. A reverse rotation restricting recess for restricting the rotation to the opposite side is formed in a notch. In this case, the lever is provided with the rotation operation portion so as to protrude toward the opposing wall portion with respect to the normal direction of the side surface of the terminal housing portion with respect to the lever main body. In addition, the rotation operation portion can be easily rotated, which is suitable for reducing the size of the lever-type connector. Since the counter wall is formed with a notch for the reverse rotation restricting recess that comes into contact with the lever at the standby position, the lever can be rotated from the standby position to the side opposite to the fitting position side. Can be regulated. In other words, since the reverse rotation from the standby position of the lever can be regulated by using the rotation operation unit and the opposing wall portion that overlap each other in the normal direction of the side surface of the terminal accommodating portion, a special reverse rotation is provided. Compared with the case where a restricting structure is provided, the structure can be simplified and further useful in reducing the size.

  ADVANTAGE OF THE INVENTION According to this invention, reduction of a number of parts can be aimed at, making the accommodation work | operativity of a terminal metal fitting favorable.

When the lever body 33a is accommodated in the lever accommodating space LS of the lever accommodating portion 35 described above, the lever 33 is pivotally supported by fitting the shaft portion 34d into the bearing hole portion 33b, and the cam 33 As the male connector 10 is rotated clockwise from the standby position (FIG. 3) allowing the cam pin 13a of the male connector 10 to enter the groove 33c to the fitting position (FIG. 4), the male connector 10 is relatively moved. It can be pulled into the fitted state. The cam groove 33c has a substantially arc shape (substantially spiral) so as to gradually approach the bearing hole 33b, which is a rotation shaft, from the entrance portion 33c1 to the back end portion 33c2. It is arranged in the cam pin receiving groove 35c of the portion 35 and opens forward.

  As shown in FIGS. 3 and 4, the lever main body 33 a includes a standby position lock arm 33 d for holding the lever 33 in the standby position, and a fitting position lock for holding the lever 33 in the fitting position. Arms 33e are provided respectively. As shown in FIG. 3, the standby position lock arm 33d extends in a cantilevered manner from the vicinity of the entrance 33c1 of the cam groove 33c, and extends in the direction along the plate surface of the lever main body 33a with the base end as a fulcrum. It is possible to bend elastically. In the state where the lever 33 is arranged at the standby position, the standby position lock arm 33d enters the release portion receiving recess 35d and is engaged with the standby position lock portion 35f, so that the lever 33 Can be held in a state where the rotation from the standby position to the fitting position side is restricted. The fitting position lock arm 33e extends in a cantilever manner by inserting a pair of slits into a portion of the lever body 33a opposite to the standby position lock arm 33d side with respect to the cam groove 33c. It is provided and can be elastically bent in a direction (Z-axis direction) orthogonal to the plate surface of the lever main body 33a with the base end portion as a fulcrum. The engagement position lock arm 33e is an unlock operation portion 33e1 whose free end can perform an unlock operation, and the engagement position lock portion 35g is located at the front side of the unlock operation portion 33e1. A locking portion 33e2 that can be locked to is recessed. The engagement position lock arm 33e is entirely exposed to the outside of the lever housing portion 35 when the lever 33 is disposed at the standby position, but as shown in FIG. 4, the lever 33 is at the engagement position. In the arranged state, it extends straight along the X-axis direction (fitting direction), and the locking portion 33e2 is locked to the fitting position locking portion 35g.

  As shown in FIGS. 3 and 6, a rotation operation portion 33f for rotating the lever 33 is provided at the end portion of the lever main body 33a on the lock release operation portion 33e1 side of the fitting position lock arm 33e. Is provided. Specifically, the rotation operation portion 33f includes a portion that is connected to both sides of the lever main body 33a with the fitting position lock arm 33e interposed therebetween, and a pair of bridging portions 33f1 that bridge the portions. These have an annular shape surrounding the fitting position lock arm 33e. The rotation operation portion 33f is opposite to the lever main body 33a in the Z-axis direction (the normal direction of the plate surface of the lever main body 33a, the wall surface of the opposing wall portion 35b, and the side surface 34e of the terminal accommodating portion 34). They are provided so as to protrude from the wall 35b side and the terminal accommodating portion 34 side, respectively. In addition, the rotation operation portion 33f has a thickness (high) such that the outer surface on the upper side (opposing wall portion 35b side) in the Z-axis direction protrudes outside the outer surface of the thick portion 35h provided on the facing wall portion 35b. A). Accordingly, when the operator rotates the lever 33, the operated range (pressed area) in the rotating operation portion 33f is secured widely, so that the lever 33 and the lever-type connector 30 can be rotated even if they are small. It is possible to easily perform a moving operation. The rotation operation portion 33f projects a rotation operation (release operation) toward the standby position by moving the lever 33 set to the engagement position by projecting toward the opposite side to the engagement position lock arm 33e side. A finger hook 33f2 is provided so that an operator can hook his / her finger when performing the operation.

  And the lever type connector 30 which concerns on this Embodiment 1 is the structure where the rear end surface 33g of the lever 33 made into the fitting position and the rear end surface 31a of the housing 31 make the same shape, as shown in FIG. It is said that. Specifically, as shown in FIG. 3, the lever 33 is arranged such that a part (including most of the rotation operation portion 33 f) protrudes rearward from the rear end surface 31 a of the housing 31 at the standby position. On the other hand, in the fitting position, as shown in FIG. 4, the entire region is arranged so as to overlap with the housing 31 in a plan view, and the rear end surface 33 g of the lever 33 is arranged at the rear end surface of the housing 31. It is flush with 31a. With such a configuration, when the operation of accommodating the terminal fitting 32 in the terminal accommodating portion 34 of the housing 31 is performed, as shown in FIG. Since the rear end surface 33g is arranged so as to be flush with the rear end surface 31a of the housing 31, the lever 33 can be prevented from protruding rearward from the rear end surface 31a of the housing 31, so that the terminal fitting 32 is accommodated in the terminal by the lever 33. It is difficult for a situation in which the work accommodated in the portion 34 is hindered. Thus, since the workability of housing the terminal fitting 32 can be improved without adopting a configuration in which the lever and the sub-connector are housed in the holder as in the conventional patent document 1, the number of parts can be reduced and the number of assembly steps can be reduced. Can be reduced. Furthermore, when the lever 33 is rotated from the standby position to the fitting position, if the rear end surface 33g of the lever 33 projects rearward from the rear end surface 31a of the housing 31, the lever 33 is fitted. Since the fitting position has not been reached and the fitting state has not been reached, the turning operation of the lever 33 is stopped halfway, and when a half-fitting state occurs, it can be detected. .

  Here, as described above, the rotation operation portion 33f of the lever 33 is provided so as to protrude from the lever main body 33a to both the upper and lower sides in the Z-axis direction, as shown in FIGS. The protruding portions on both sides are in the Z-axis direction with respect to the opposing wall portion 35b of the lever accommodating portion 35 and a part of the housing 31 (the method on the plate surface of the opposing wall portion 35b and the side surface 34e of the terminal accommodating portion 34 opposed thereto). (Line direction) is an overlapping arrangement. On the other hand, since the rear end surface 33g of the lever 33 is flush with the rear end surface 31a of the housing 31 at the fitting position as described above, the entire area of the rotation operation portion 33f is flat with the housing 31. It is arranged so as to overlap when viewed (viewed from the Z-axis direction). On the other hand, the opposing wall portion 35b of the lever housing portion 35 receives the first bridge portion 33f1 in the Z-axis direction of the rotation operation portion 33f of the lever 33 disposed at the fitting position. An operation portion receiving recessed portion (excessive rotation restricting recessed portion) 36 is notched. Furthermore, the rear end portion of the housing 31 receives a second operation portion for receiving the lower bridging portion 33f1 in the Z-axis direction of the rotation operation portion 33f of the lever 33 disposed at the fitting position. A recess 37 is formed in the cutout. When the lever 33 is rotated until the lever 33 reaches the fitting position, the first operation portion receiving recess 36 and the second operation portion receiving recess 37 are formed on the front end surfaces of the upper and lower bridge portions 33f1 of the rotation operation portion 33f. By abutting over almost the entire region, it is possible to restrict the lever 33 from being further rotated from the fitting position to the side opposite to the standby position side (forward direction). In this way, since the excessive rotation from the fitting position in the lever 33 can be restricted by using the rotation operation portion 33f and the opposing wall portion 35b that overlap each other in the Z-axis direction, a special dedicated excessive rotation is temporarily provided. Compared with the case where a restricting structure is provided, the structure can be simplified and further useful in reducing the size.

  As shown in FIG. 3, in addition to the first operation portion receiving recess 36, the opposing wall portion 35b forming the lever housing portion 35 has a Z-axis of the rotation operation portion 33f of the lever 33 arranged at the standby position. A third operating portion receiving recess (reverse rotation restricting recess) 38 for receiving the upper bridging portion 33f1 in the direction is cut out. The third operation portion receiving recess 38 is adjacent to the shaft portion 34d side (opposite to the finger insertion recess 39 side described later) in the Y-axis direction with respect to the first operation portion receiving recess 36 in the opposing wall portion 35b. It is arranged with. The front end position (contact position with respect to the lever 33) of the third operation portion receiving recess 38 is disposed rearward of the front end position (contact position with respect to the lever 33) of the first operation portion receiving recess 36. The cutout range in the X-axis direction with respect to the portion 35b is narrower than the cutout range of the first operation portion receiving recess 36 with respect to the opposing wall portion 35b. Then, of the upper bridging portion 33f1 in the Z-axis direction that forms the rotation operation portion 33f of the lever 33, the end portion on the side opposite to the finger hooking portion 33f2 side is in the state where the lever 33 is in the standby position. 3 By abutting on the operation portion receiving recess 38, it is possible to restrict reverse rotation in which the lever 33 rotates from the standby position to the opposite side (reverse direction) from the fitting position side. As described above, the reverse rotation from the standby position in the lever 33 can be restricted by using the rotation operation part 33f and the opposing wall part 35b that overlap each other in the Z-axis direction. Compared with the case where a structure is provided, the structure can be simplified and more useful in reducing the size.

  Furthermore, as shown in FIG. 4, the lever-type connector 30 according to the first embodiment has a configuration in which the side surface 33 h of the lever 33 in the fitting position and the outer side surface 31 b of the housing 31 are flush with each other. Has been. Specifically, among the levers 33 in the fitting position, the side surface 33h of the finger hook portion 33f2 disposed at the end of the rotation operation portion 33f is flush with the outer surface 31b of the housing 31, and the same. The outer side surface 31b does not protrude outward in the Y-axis direction. Therefore, in a state where each female connector 20 and the lever type connector 30 are fitted to the male connector 10, the lever 33 of the lever type connector 30 is moved from the outer surface 31b of the housing 31 to the Y position as shown in FIGS. It is the arrangement | positioning which does not protrude to the adjacent female connector 20 side about an axial direction. According to such a configuration, when the work procedure for fitting the lever-type connector 30 to the male connector 10 and then fitting the adjacent female connector 20 is adopted, the female connector 20 is fitted. When mating, the female connector 20 is less likely to interfere with the lever 33 of the lever-type connector 30, so that the female connector 20 can be smoothly fitted and the workability is excellent.

  If the side surface 33h of the lever 33 in the fitting position as described above is flush with the outer side surface 31b of the housing 31, the fitting workability of the adjacent female connectors 20 is excellent. When the lever connector 30 is detached from the male connector 10, it is difficult for an operator to put a finger on the finger hook portion 33f2 in the rotation operation portion 33f of the lever 33, and there is a concern that the detachability of the lever connector 30 may be deteriorated. The Therefore, in the first embodiment, a finger is placed on the side end portion of the housing 31 that is disposed so as to overlap the rotation operation portion 33f in the Z-axis direction when a finger is placed on the finger hook portion 33f2 of the rotation operation portion 33f. A finger insertion recess 39 for facilitating insertion of the finger is formed in the cutout. The finger insertion recess 39 is opened rearwardly in the X-axis direction, rightward in the Y-axis direction, and upward in the Z-axis direction by cutting out the side end portion of the housing 31. In the state of being arranged at the joint position, it has a finger insertion space FS in which a finger can be inserted between the finger hooking portion 33f2. The finger insertion space FS is opened upward in the Z-axis direction and laterally in the Y-axis direction, and a finger can be inserted through these opening portions. The finger insertion recess 39 is formed by notching the side end portion of the housing 31 over the entire area overlapping with the finger hook portion 33f2 of the rotation operation portion 33f in the Z-axis direction. Can accept. The finger insertion recess 39 is adjacent to the first operation portion receiving recess 36 provided on the opposing wall portion 35b of the lever accommodating portion 35 on the opposite side to the third operation portion receiving recess 38 side in the Y-axis direction. It is arranged with. The front end position of the finger insertion recess 39 is disposed in front of the front end position of the first operation portion receiving recess 36, and the notch range in the X-axis direction with respect to the side end portion of the housing 31 has an opposing wall portion. It is wider than the notch range of the first operating portion receiving recess 36 with respect to 35b. According to such a configuration, in the state where the lever connector 30 and the female connector 20 adjacent thereto are fitted to the male connector 10, for example, when removing the lever connector 30, the finger insertion recess 39, Since the operator can put his finger into the finger putting space FS between the finger holding portion 33f2 of the lever 33 in the fitting position (FIG. 13), the operator can put the finger on the finger holding portion 33f2. The rotation operation portion 33f can be easily rotated. Thereby, the side surface 33h of the lever 33 in the fitting position is flush with the outer side surface 31b of the housing 31, while ensuring good fitting workability between the adjacent female connectors 20, The removal workability of the lever-type connector 30 can be improved.

  The first embodiment has the structure as described above, and its operation will be described next. First, when the lever connector 30 is assembled, the lever 33 is assembled to the housing 31 in advance. The lever 33 is inserted from the rear into the lever accommodating space LS provided in the lever accommodating portion 35 of the housing 31 (FIG. 6), and the bearing hole portion 33b is fitted to the shaft portion 34d disposed therein. And is pivotally supported. When the lever 33 accommodated in the lever accommodating portion 35 is arranged at the fitting position, the fitting position lock arm 33e is locked to the fitting position lock portion 35g, and the both bridging portions 33f1 of the rotation operation portion 33f are provided. Is brought into contact with the first operating portion receiving recess 36, whereby the lever 33 is held in a state in which it cannot rotate from the fitting position.

  Then, the operation | work which accommodates the terminal metal fitting 32 with respect to the housing 31 assembled | attached in the state which hold | maintained the lever 33 in the fitting position as mentioned above is performed. The terminal fitting 32 connected to the terminal of the electric wire W is inserted from the rear side into the terminal fitting accommodating chamber 34a provided in the terminal accommodating portion 34 of the housing 31 from the state shown in FIG. Here, the lever 33 assembled to the housing 31 is held in the fitting position, and the rear end surface 33g thereof is flush with the rear end surface 31a of the housing 31, and is rearward from the rear end surface 31a of the housing 31. Protruding is avoided. In other words, it is avoided that the lever 33 is disposed so as to protrude like a bowl on the upper side of the terminal accommodating portion 34 in the Z-axis direction. In other words, the lever 33 hardly forms a shadow in a plan view with respect to the space behind the terminal accommodating portion 34. Accordingly, it is easy for the operator to visually confirm the position of the terminal fitting housing chamber 34a into which the terminal fitting 32 is to be inserted, so that the terminal fitting 32 is the target terminal fitting as shown in FIGS. It can be smoothly inserted into the storage chamber 34a. Therefore, the insertion workability of the terminal fitting 32 is excellent. In FIGS. 7 to 9, only one of the plurality of terminal fittings 32 is shown as a representative for convenience of space.

  When all the terminal fittings 32 are accommodated in the housing 31, the operation of fitting the lever connector 30 to the male connector 10 is subsequently performed. Prior to performing the fitting operation, the lock arm 33e for fitting position is pushed downward in the Z-axis direction to release the lock, and the lever 33 is rotated from the fitting position to the standby position. When the lever 33 is arranged at the standby position, the standby position lock arm 33d is locked to the standby position lock portion 35f, and both bridging portions 33f1 of the rotation operation portion 33f are formed in the third operation portion receiving recess 38. By abutting, the lever 33 is held in a state in which the lever 33 cannot be rotated from the standby position. The lever connector 30 is fitted into the lever connector fitting portion 13 of the male connector 10 from the state shown in FIG. When the lever-type connector 30 is fitted into the lever-type connector fitting portion 13 to a predetermined depth, as shown in FIG. 10, the cam pin 13a is in the cam pin receiving groove portion 35c, and the release portion 13b is in the release portion receiving recess 35d. Each guide rib 13c enters each guide rib receiving recess 34b, 35e, and each erroneous fitting restricting portion 13d enters each restricting portion receiving recess 34c. When the fitting further proceeds from the state in which the release portion 13b is in contact with the distal end portion of the standby position lock arm 33d in the release portion receiving recess 35d, as shown in FIG. When the lock arm 33d is bent, the locked state with respect to the standby position lock portion 35f is released. This allows the lever 33 to be rotated from the standby position to the fitting position. At the time of releasing the lock, the cam pin 13 a enters the entrance 33 c 1 in the cam groove 33 c of the lever 33.

  When the unlocked lever 33 is rotated clockwise from the standby position, the cam pin 13a moves from the entrance 33c1 to the back end 33c2 side (shaft 34d side) along the periphery of the cam groove 33c. By doing so, the housing 31 is relatively drawn toward the male housing 11 side, and the fitting proceeds. At this time, the cam action is exhibited by the cam pin 13a engaging with the peripheral edge of the cam groove 33c, so that the fitting operation can be performed with a low operation force. When performing the rotation operation of the lever 33, the rotation operation portion 33f is extended vertically in the Z-axis direction relative to the lever main body 33a, so that the rotation operation is easy even if the lever 33 is small. Therefore, the lever-type connector 30 is suitable for miniaturization. When the lever 33 is rotated to the mating position, as shown in FIG. 12, both the housings 11 and 31 reach the proper mating depth, and both the terminal fittings 12 and 32 are normally conductively connected. The cam pin 13a is disposed on the inner end 33c2 of the cam groove 33c. At this time, the engagement position lock arm 33e is engaged with the engagement position lock portion 35g, and both bridging portions 33f1 of the rotation operation portion 33f are brought into contact with the first operation portion receiving recess 36. Thus, the lever 33 is held in a state in which the lever 33 cannot be rotated from the fitting position. As described above, both the housings 11 and 31 are held in a properly fitted state.

  By the way, when performing the rotation operation of the lever 33 as described above, the operator may stop the rotation operation in a state before the lever 33 reaches the fitting position. In that case, as shown by a two-dot chain line in FIG. 12, a part of the lever 33 protrudes rearward from the rear end surface 31 a of the housing 31. On the other hand, if the lever 33 has reached the fitting position, the lever 33 does not protrude rearward from the rear end surface 31a of the housing 31, and the rear end surface 33g of the lever 33 is flush with the rear end surface 31a of the housing 31. Arranged in the form. Therefore, if the lever 33 protrudes rearward from the rear end surface 31a of the housing 31, the lever 33 has not reached the fitting position, and has not reached the fitting state. ) Is known to the operator, so that the half-fitted state can be easily detected. When the half-fitted state is detected, the operator may perform the turning operation of the lever 33 until the rear end surface 33g of the lever 33 is flush with the rear end surface 31a of the housing 31.

  When the lever-type connector 30 is removed from the male connector 10 due to maintenance or the like, the lock position operating portion 33e1 of the lock arm 33e for fitting position is pressed from the state shown in FIGS. 13 and 14 to lock the fitting position. The arm 33e is bent to rotate counterclockwise from the fitting position by operating the turning operation portion 33f while releasing the locking state of the locking portion 33e2 with respect to the fitting position lock portion 35g. Let When the rotation operation unit 33f is operated, the side surface 33h of the rotation operation unit 33f is flush with the outer surface 31b of the housing 31, so that it is difficult to put a finger on the finger hooking unit 33f2. Since the finger insertion recess 39 is provided so as to have the finger insertion space FS between the finger hooking portion 33f2 by cutting out the side end portion of the housing 31, the operator puts his finger into the finger insertion space FS. Thus, it is possible to easily hook the finger on the finger hook portion 33f2. Thereby, the operation | work which rotates the lever 33 toward a standby position from a fitting position can be performed easily, and it is excellent in the isolation | separation workability | operativity of the lever-type connector 30. FIG. As the lever 33 is rotated from the fitting position to the standby position, the cam pin 13a moves from the rear end portion 33c2 of the cam groove 33c to the entrance portion 33c1, so that the housing 31 is removed from the male housing 11. The withdrawal proceeds in a relatively separated manner.

  As described above, the lever-type connector 30 of the first embodiment has the terminal fitting 32 and the cam groove 33c for receiving the cam pin 13a provided in the male connector (mating connector) 10, and the cam pin 13a with respect to the cam groove 33c. A lever 33 that pulls the male connector 10 into the mating state as it is rotated from the standby position allowing entry into the mating position, and the male connector 10 can be mated, and the terminal fitting 32 is accommodated. A housing (connector housing) 31 having a terminal housing portion 34 for receiving the lever 33 and a lever housing portion 35 for housing the lever 33. A housing 31 disposed at a position to be formed.

  According to the above configuration, in order to fit the male connector 10 into the housing 31, first, the cam pin 13 a of the male connector 10 is caused to enter the cam groove 33 c of the lever 33 with the lever 33 in the standby position. Then, when the lever 33 is rotated from the standby position to the fitting position, the male connector 10 is drawn by the cam action of the cam pin 13a and the cam groove 33c to reach the fitting state.

  On the other hand, when the operation of accommodating the terminal fitting 32 in the terminal accommodating portion 34 of the housing 31 is performed, the lever 33 accommodated in the lever accommodating portion 35 of the housing 31 is set to the mating position, thereby setting the mating position. Since the rear end surface 31a of the housing 31 is flush with the rear end surface 33g of the lever 33, there is a situation in which the operation of housing the terminal fitting 32 in the terminal accommodating portion 34 is hindered by the lever 33. It has become difficult. Thus, since the workability of housing the terminal fitting 32 can be improved without adopting a configuration in which the lever and the sub-connector are housed in the holder as in the conventional patent document 1, the number of parts can be reduced and the number of assembly steps can be reduced. Can be reduced.

  The lever 33 protrudes rearward from the rear end surface 31a of the housing 31 at the standby position, but the rear end surface 33g is arranged at a position where the rear end surface 33g is flush with the rear end surface 31a of the housing 31 at the fitting position. It is accommodated in the lever accommodating portion 35. In this way, when the male connector 10 is fitted into the housing 31, when the lever 33 is rotated from the standby position to the fitting position, the lever 33 protrudes rearward from the rear end surface 31a of the housing 31. From the state, it reaches a state that is flush with the rear end surface 31a of the housing 31. Therefore, when the lever 33 is rotated, if the lever 33 protrudes rearward from the rear end surface 31a of the housing 31, the lever 33 has not reached the fitting position and has not reached the fitting state. As a result, the half-fitted state can be detected.

  In addition, the lever housing portion 35 has an opposing wall portion 35b arranged in an opposing manner with a space that can accommodate the lever 33 with respect to the side surface 34e of the terminal housing portion 34, whereas the lever 33 is The lever main body 33a accommodated between the terminal accommodating portion 34 and the opposing wall portion 35b, and the lever main body 33a protrudes at least toward the opposing wall portion 35b in the normal direction of the side surface 34e of the terminal accommodating portion 34. A rotation operation portion 33f provided, and the lever 33 further moves from the fitting position by abutting the rotation operation portion 33f of the lever 33 at the fitting position on the opposing wall portion 35b. A first operating portion receiving recess (excessive rotation restricting recess) 36 that restricts rotation is formed in a notch. In this way, the lever 33 is provided with the rotation operation portion 33f so as to protrude toward the opposing wall portion 35b in the normal direction of the side surface 34e of the terminal accommodating portion 34 with respect to the lever main body 33a. Even if the lever 33 is small, the rotation operation portion 33f can be easily rotated, which is preferable in reducing the size of the lever connector 30. Then, when the lever 33 is rotated to the fitting position, the first operation portion receiving recess 36 is formed in the opposing wall portion 35b so that the first operation portion receiving recess 36 comes into contact with the rotating operation portion 33f. Therefore, it is possible to restrict the lever 33 from further rotating from the fitting position. That is, excessive rotation of the lever 33 from the fitting position can be restricted using the rotation operation portion 33f and the opposing wall portion 35b that overlap each other in the normal direction of the side surface 34e of the terminal accommodating portion 34. Compared to a case where a separate dedicated excessive rotation restricting structure is provided, the structure can be simplified and further useful in reducing the size.

  In addition, the lever housing portion 35 has an opposing wall portion 35b arranged in an opposing manner with a space that can accommodate the lever 33 with respect to the side surface 34e of the terminal housing portion 34, whereas the lever 33 is The lever main body 33a accommodated between the terminal accommodating portion 34 and the opposing wall portion 35b, and the lever main body 33a protrudes at least toward the opposing wall portion 35b in the normal direction of the side surface 34e of the terminal accommodating portion 34. A rotation operation portion 33f provided, and the opposing wall portion 35b is in contact with the rotation operation portion 33f of the lever 33 at the standby position, so that the engagement position side from the standby position is A third operating portion receiving recess (reverse rotation restricting recess) 38 that restricts the rotation to the opposite side is cut out. In this way, the lever 33 is provided with the rotation operation portion 33f so as to protrude toward the opposing wall portion 35b in the normal direction of the side surface 34e of the terminal accommodating portion 34 with respect to the lever main body 33a. Even if the lever 33 is small, the rotation operation portion 33f can be easily rotated, which is preferable in reducing the size of the lever connector 30. Further, since the third operation portion receiving recess 38 that is in contact with the lever 33 in the standby position is cut out in the opposing wall portion 35b, the lever 33 is moved from the standby position to the side opposite to the fitting position side. The rotation can be restricted. That is, reverse rotation of the lever 33 from the standby position can be restricted using the rotation operation portion 33f and the opposing wall portion 35b that overlap each other in the normal direction of the side surface 34e of the terminal accommodating portion 34. Compared with the case where a dedicated reverse rotation restricting structure is provided, the structure can be simplified and more useful in miniaturization.

<Embodiment 2>
A second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the rear end surface 133g of the lever 133 in the fitting position and the rear end surface 131a of the housing 131 are changed.

In other words, the lever 133 in the fitting position is arranged such that its rear end surface 133g is retracted forward of the rear end surface 131a of the housing 131. Even in such a configuration, if the lever 133 is set to the fitting position when the terminal fitting 134 (not shown) is accommodated in the terminal accommodating portion 134 of the housing 131, the lever 133 can be moved to the rear of the housing 131. Since it is avoided to protrude rearward from the end surface 131a, it is difficult for the lever 133 to interfere with the operation of housing the terminal fitting in the terminal housing portion 134.

  As described above, the lever-type connector 130 of the present embodiment has the terminal fitting and the cam groove 133c that receives the cam pin provided in the male connector (mating connector), and waits to allow the cam pin to enter the cam groove 133c. A lever 133 that pulls the male connector into the mating state as it is rotated from the position to the mating position, a terminal accommodating portion 134 that is capable of mating with the male connector and that accommodates the terminal fitting, and a lever A housing (connector housing) 131 having a lever accommodating portion 135 for accommodating 133, the housing being arranged at a position where the rear end surface 131a protrudes rearward from the rear end surface 133g of the lever 133 in the fitting position. 131.

  In this way, when performing the operation of accommodating the terminal fitting in the terminal accommodating portion 134 of the housing 131, the lever 133 accommodated in the lever accommodating portion 135 of the housing 131 is set to the mating position. Since the rear end surface 131a of the housing 131 protrudes rearward with respect to the rear end surface 133g of the lever 133 that is positioned, there is a situation in which the operation of housing the terminal fitting in the terminal accommodating portion 134 is hindered by the lever 133. It is hard to occur. As described above, since the housing workability of the terminal fitting can be improved without adopting a configuration in which the lever and the sub-connector are respectively housed in the holder as in the conventional patent document 1, the number of parts can be reduced and the assembly man-hour can be reduced. Reduction can be achieved.
