  However, since the locking piece is configured such that the locking portion is provided at the tip of the arm having a predetermined length, the length from the rotation center of the lever body to the locking portion (the locking portion) It is necessary to form a relatively long radius of rotation. This is because if the rotation radius of the locking portion is shortened, the space allowed for arm formation becomes small, the arm becomes small, and the rigidity of the lever body becomes weak due to the slit portion necessary for arm formation. It is. Therefore, in the lock piece in which the locking portion is provided at the tip of the arm, it is necessary to ensure the rotation radius of the locking portion to be long to some extent. As a result, the lever main body becomes large in the plate surface direction. ing.

  The present invention has been completed based on the above circumstances, and an object thereof is to reduce the size of the lever while ensuring the rigidity of the lever.

  The present invention relates to a connector with a lever which is adapted to be engaged and disengaged with a mating connector by rotating the lever, and has a flat plate-like cam plate, and the cam plate has a plate thickness direction. A lever provided with a pair of flat plate surfaces orthogonal to each other and a lock piece that supports the lever assembled at the initial position so as to be rotatable toward the mating position and holds the lever at the mating position The lock piece has an arm that can be elastically deformed in the thickness direction of the cam plate, and the arm is provided with a housing side protrusion, while the lever is engaged with the housing side protrusion. It is characterized by having a structure including a lever lock portion provided with a lever-side protrusion that can be stopped.

  According to such a configuration, since the lock piece having the arm is provided not on the lever side but on the housing side, the rigidity of the lever can be ensured. This is because if the arm is formed by protruding from the housing, it is not necessary to form a slit in the housing. Further, since it is not necessary to rotate the arm, the lever-side protrusion can ride on the housing-side protrusion in a vertical posture even when the lever is downsized. This is because the lever-side protrusion is generally shorter than the arm length, and the lever-side protrusion is likely to take a vertical position with respect to the housing-side protrusion even when the rotation radius of the lever-side protrusion is shortened. is there. Therefore, the lever can be reduced in size while ensuring the rigidity of the lever.

The following configuration is preferable as an embodiment of the present invention.
The lock piece is formed with a release operation part that flexes and deforms the arm so as to release the locked state of the housing side protrusion and the lever side protrusion at the fitting position. It is good also as a structure provided with the arch part which covers a housing side protrusion, making a cancellation | release operation part face outside.
According to such a structure, the latching | locking part of a housing side protrusion and a lever side protrusion can be protected by an arch part in a fitting position. Further, since the release operation part faces the outside from the arch part, the arch part does not get in the way and the release operation does not become difficult.

The housing is provided with a lever accommodating portion that accommodates the lever therein, and this lever accommodating portion has an opening that opens to the rear, and a lock piece projects rearward from the opening. It is good also as composition which has.
According to such a configuration, since the lock piece can be disposed outside the lever housing portion, the lever housing portion can be reduced in size, and the housing can be reduced in size.

The lock piece is configured such that the arm protrudes rearward along the plate surface of the cam plate, so that the arm and cam plate are moved at the initial position or while the lever is rotated from the initial position to the fitting position. It is good also as a structure which controls that an electric wire enters between the surfaces and an arm reverses.
According to such a structure, it can control that a lock piece reverse | inverts and bends and deform | transforms by an electric wire entering between the arm and the board surface of a cam board.

It is good also as a structure by which the cancellation | release recessed part which makes a cancellation | release operation part face outside in a fitting position is provided in the rear-end part of an arch part.
According to such a configuration, since the release operation part faces the outside through the release recess, it is not necessary to project the release operation part behind the arch part, and the entire arm including the release operation part in the longitudinal direction Can be reduced in size.

It is good also as a structure by which the mounting recessed part in which a part of lever lock part fits in the opening part of a lever accommodating part in a fitting position is provided.
According to such a configuration, a part of the lever lock portion can be fitted into the mounting recess, so that the amount of the lever lock portion protruding rearward from the opening of the lever housing portion can be reduced.

The lever accommodating portion may be provided over the entire width of the housing.
According to such a configuration, a dead space in which the lever is not accommodated in the width direction of the housing is not formed, which can contribute to downsizing of the housing.

  According to the present invention, the lever can be reduced in size while ensuring the rigidity of the lever.

<Embodiment>
An embodiment of the present invention will be described with reference to the drawings of FIGS. The connector 10 according to the present embodiment is a connector with a lever that is adapted to be engaged with and detached from a board connector (an example of the “mating connector” of the present invention) 50 by rotating the lever 40. The circuit board connector 50 constitutes an automobile airbag circuit. Hereinafter, in each component member, the fitting surface side of both connectors 10 and 50 will be described as the front, the opposite side as the rear, and the upper side in FIG. 1 as the upper side and the lower side as the lower side.

  The board connector 50 is a so-called male connector, which is a housing made of synthetic resin (referred to as a male housing 51) and a plurality of terminal fittings (male terminal fittings 52) attached to the male housing 51. (Refer to FIG. 8).

  The male housing 51 includes a hood portion 53 that opens forward, and the connector 10 is fitted into the hood portion 53. A plurality of male terminal fittings 52 bent in an L shape are attached to the male housing 51 in a state in which the tip portions protrude into the hood portion 53.

  The male housing 51 is provided with a short-circuit releasing portion 54 that protrudes into the hood portion 53 to cancel the short-circuit state of the female-side terminal fitting, which will be described later, in the process of fitting both the connectors 10 and 50. . The short-circuit releasing unit 54 is provided at a position corresponding to the short terminal housing chamber 13 of the female housing 11.

  A cylindrical cam pin 55 is formed on the upper wall of the hood 53 so as to protrude downward (toward the internal space of the hood 53). The cam pin 55 is provided at a position closer to the front end than the center in the front-rear direction of the hood portion 53.

  The connector 10 is a so-called female connector, and includes a synthetic resin housing (referred to as a female-side housing 11) and a plurality of terminal fittings.

  As shown in FIG. 4, the terminal fitting includes a female terminal fitting (not shown) that can be connected to the male terminal fitting 52 and a short terminal 30 that short-circuits a pair of adjacent female terminal fittings. ing. The female terminal fitting has a substantially cylindrical shape and a main body portion connected to the male terminal fitting 52 and a barrel portion connected to the end of the electric wire are connected to each other and extend long.

Further, the receiving path 21 is provided at a position eccentric from the center to one side in the width direction of the female housing 11.

  As shown in FIG. 6, the bottom wall 19A of the lever accommodating portion 19 is provided with a locking piece 22 for holding the lever 40 in the initial position. The locking piece 22 has a cantilever shape extending forward, and a locking projection 22A protruding upward is provided at the free end thereof. The locking piece 22 is formed at a substantially central position in the front-rear direction of the female-side housing 11 (above the retainer mounting portion 17), and is located directly below the receiving path 21 in the bottom wall 19A.

  The lever 40 is a rotary lever and includes a cam plate 41 made of synthetic resin and having a flat plate shape. The cam plate 41 has a pair of plate surfaces that are orthogonal to the plate thickness direction and have a planar shape. The plate thickness dimension of the cam plate 41 is the thickness dimension of the short terminal 30, specifically, the vertical dimension of the parallel portion (the portion excluding the contact portion 34) of the base portion 31 and the elastic contact piece 32 in the short terminal 30. (See FIG. 4).

  The lever 40 is disposed along the upper surface of the bottom wall 19A of the lever housing portion 19 and is assembled to the lever housing portion 19 with a slight clearance between the upper wall 11A and the bottom wall 19A. Further, the lever 40 is arranged to be shifted rearward from the short terminal 30, and a rear half of an operation portion 46 described later protrudes rearward from the female housing 11.

  A support shaft (not shown) that rotatably supports the lever 40 is provided on the bottom wall 19A of the lever accommodating portion 19 so as to protrude upward. It is arranged behind the locking piece 22 in the approximate center of the direction. On the other hand, a substantially circular bearing hole (not shown) into which the support shaft is fitted is provided in the approximate center of the lower surface of the cam plate 41, and the portion from the edge of the cam plate 41 to the bearing hole is An assembly groove (not shown) that allows the support shaft to enter is recessed.

  A cam groove 44 is formed on the upper surface of the cam plate 41 to engage the cam pin 55 of the board connector 50. The cam groove 44 is a recess extending from the edge of the cam plate 41 to a bearing hole (not shown). When the lever 40 is in the initial position shown in FIG. 6, the inlet 44 </ b> A of the cam groove 44 is formed in the female housing 11. The cam pin 55 can be received in the cam groove 44.

  On the inlet 44A side of the cam groove 44, a locking hole 45 is provided for locking the locking projection 22A of the female housing 11 when the lever 40 is in the initial position. The locking hole 45 has a rectangular shape and penetrates the bottom wall of the cam groove 44 in the vertical direction. When the locking projection 22A is locked in the locking hole 45, the lever 40 is restricted from rotating from the initial position to the fitting position side (clockwise direction in the figure) shown in FIG. 2, and is held at the initial position. Is done.

  As shown in FIG. 1, the lever 40 has an opening through which the lock piece 15 can be inserted between the lever plate 40 and the cam plate 41, and a lever lock portion 42 that can be locked with the lock piece 15. Is provided. The lever lock portion 42 includes an arch portion 43 that protrudes upward from the cam plate 41 to form a substantially gate shape, and an operation portion 46 that is operated by applying a finger when the lever 40 is rotated. The operation portion 46 is provided in a form protruding from the side edge of the arch portion 43 to the side.

  The lower surface of the arch portion 43 is a facing portion that faces the arm 15A of the lock piece 15 at the fitting position. As shown in FIG. 4, a lever side protrusion 47 is provided on the lower surface of the arch portion 43. The lever side protrusion 47 is formed to protrude downward from the lower surface of the arch portion 43. When the turning operation of the lever 40 is completed, the arch portion 43 is positioned above the lock piece 15, and the lever side protrusion 47 is engaged with the housing side protrusion 15 </ b> B in the front-rear direction, so that the lever 40 is brought into the fitting position. The rotation to the initial position is restricted by being held. In addition, in the portion of the cam plate 41 that faces the arch portion 43, a bending allowable recess 48 that allows the elastic deformation of the lock piece 15 is formed.

  As shown in FIG. 2, a release recess 49 is provided at the rear end of the upper wall of the arch portion 43 so that the release operation portion 15 </ b> C faces upward at the fitting position. By inserting a finger from the release recess 49 and pushing the release operation portion 15C downward, the housing-side protrusion 15B can be displaced downward to release the locked state with the lever-side protrusion 47. Although the upper surface of the release operation portion 15 </ b> C faces the arch portion 43 through the release recess 49, the rear end of the release operation portion 15 </ b> C does not protrude rearward from both side walls of the arch portion 43. In other words, the arch portion 43 is configured to cover the housing-side protrusion 15B with the release operation portion 15C facing outside while protecting the lock piece 15 from an external impact at the fitting position.

  The present embodiment is configured as described above, and its operation will be described subsequently. First, a method for assembling the lever 40 will be described. The lever 40 is housed by being pushed into the lever housing portion 19 from behind. Specifically, the lever 40 is leveled, and the cam plate 41 is inserted into the lever accommodating portion 19 while the assembly groove is aligned with the support shaft, and the support shaft and the bearing hole are fitted. Then, the lever 40 is rotated to the initial position, and the locking projection 22A and the locking hole 45 are fitted. Accordingly, the rotation of the lever 40 toward the fitting position is restricted, and the assembly of the lever 40 to the female housing 11 is completed. When the lever 40 is in the initial position, an electric wire enters between the arm 15A and the cam plate 41, and the arm 15A is restricted from being reversed upward.

Next, the fitting operation of both connectors 10 and 50 will be described.
First, the connector 10 is shallowly fitted into the hood portion 53 of the board connector 50. Then, the cam pin 55 enters the inlet 44A of the cam groove 44, pushes the locking projection 22A downward, and releases the locking with the locking hole 45. As a result, the turning operation of the lever 40 at the initial position is allowed. Here, since the cam pin 55 is provided at a position on the front side of the conventional one, even if the inlet 44A of the cam groove 44 is located on the rear side of the conventional one, the cam pin 55 is inserted into the cam groove with the same fitting amount. 44 can be fitted.

  Next, when the operating portion 46 of the lever 40 is pressed and the lever 40 is turned to the fitting position side, both the connectors 10 and 50 are pulled toward each other by the cam action due to the engagement between the cam pin 55 and the cam groove 44, and the hood The fitting of the female housing 11 to the portion 53 proceeds.

  In this fitting process, each short-circuit releasing portion 54 enters each short terminal accommodating chamber 13 and abuts on the elastic contact piece 32 of each short terminal 30 to elastically deform it upward. Thereby, the elastic contact piece 32 is separated from the female terminal fitting, and the short circuit state between the female terminal fittings is released.

  Further, when the lever 40 approaches the fitting position (that is, both the connectors 10 and 50 approach the normal fitting state), the arch portion 43 approaches the lock piece 15 from the oblique posture to the vertical posture, and the lever side protrusion When 47 comes into contact with the housing-side protrusion 15B and starts to ride, the rider assumes a vertical posture and starts riding. When the lever-side protrusion 47 rides on the housing-side protrusion 15B in a vertical posture, the lock piece 15 is bent downward and deformed.

  As soon as the lever 40 reaches the fitting position, the lock piece 15 is elastically restored, and the lever side projection 47 is locked in the front-rear direction with respect to the housing side projection 15B while being in the vertical posture. It will be in the state hold | maintained in the position, and the rotation to an initial position is controlled. In this way, both the connectors 10 and 50 are held in a proper fitted state.

  When the connectors 10 and 50 are detached, the release operation portion 15C is pressed downward through the release recess 49 to release the locked state between the lever side protrusion 47 and the housing side protrusion 15B. Subsequently, the operation unit 46 is pulled to rotate the lever 40 in the direction opposite to that during the fitting operation. Then, the lever 40 is rotated from the fitting position to the initial position, and with this rotation, the cam pin 55 moves through the cam groove 44 toward the inlet 44A, and the both connectors 10 and 50 are separated. When the lever 40 reaches the initial position, the cam pin 55 is disengaged from the cam groove 44 and both the connectors 10 and 50 are detached.

  As described above, in this embodiment, since the lock piece 15 having the arm 15A is provided on the female housing 11 side, the lever 40 can be reduced in size. That is, when the arm is provided on the lever 40 side, the distance from the rotation center of the lever 40 to the lever-side protrusion is increased in order to perform from the ride-up of the lever-side protrusion and the housing-side protrusion to the locking in the vertical posture. Where necessary, since only the lever-side protrusion 47 shorter than the arm is provided on the lever 40 side, it is possible to shorten from the pivot center of the lever 40 to the lever-side protrusion 47. Therefore, the lever 40 can be miniaturized, and the lever housing portion 19 that accommodates the lever 40 can be miniaturized, so that the female housing 11 can be miniaturized.

  Moreover, since the arch part 43 is provided and the lock piece 15 is protected, it is possible to restrict the lock piece 15 from being damaged by an external impact. Furthermore, since the release recess 49 is provided in the arch portion 43, there is no possibility that the release operation becomes difficult by providing the arch portion 43. Further, since the lock piece 15 is provided outside the lever accommodating portion 19, there is no possibility that the lever accommodating portion 19 is enlarged.

  In addition, since the arm 15A of the lock piece 15 is provided so as to protrude rearward along the plate surface of the cam plate 41, the electric wire bites between the arm 15A and the plate surface of the cam plate 41 at the initial position. It can control that arm 15A reverses. Furthermore, since a part of the lever lock part 42 fits into the mounting recess 20, the amount of the lever lock part 42 protruding to the rear of the lever housing part 19 can be reduced. In addition to this, since the lever accommodating portion 19 is provided over the entire width of the female housing 11, no dead space is formed in the width direction of the female housing 11, which contributes to downsizing of the female housing 11. sell.
