FIG. 2 is a simplified view of FIG. 2 of Patent Document 1.

Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS. 1 to 10.

FIG. 1 shows the fitted state of the lever type connector 1, and FIGS. 2 and 3 show the state before fitting the lever type connector 1. As shown in FIGS. 1 to 3, the lever type connector 1 includes a plug connector 2 and a receptacle connector 3.

The plug connector 2 includes a plug connector main body 5 attached to the end of the cable 4 and a lever 6 rotatably supported by the plug connector main body 5.

The receptacle connector 3 is used by being attached to an outer wall surface of a servomotor (not shown).

Then, by fitting the plug connector 2 to the receptacle connector 3, a plurality of conductors accommodated by the cable 4 are electrically connected to the control board of the servomotor.

The lever type connector 1 is attached not only to the servomotor but also to various electronic devices including a motor other than the servomotor and a rotation detector.

(Definition of direction)
Here, with reference to FIGS. 1 to 3, the "insertion / extraction direction", "rotation axis direction", and "axis orthogonal direction (orthogonal direction)" are defined. The insertion / extraction direction, the rotation axis direction, and the axis orthogonal direction are orthogonal to each other.

The insertion / removal direction is the direction in which the plug connector 2 is inserted into / removed from the receptacle connector 3. The insertion / removal direction includes the lower part as the fitting direction and the upper part as the removal direction. The lower direction is the direction in which the plug connector 2 approaches the receptacle connector 3 when the plug connector 2 is fitted to the receptacle connector 3. The upper direction is the opposite direction of the lower direction. Note that the terms "lower" and "upper" are merely terms used for convenience of explanation, and do not define the posture of the lever-type connector 1 when used.

The rotation axis direction is the direction in which the rotation axis 6C of the lever 6 rotatably supported by the plug connector main body 5 extends. Hereinafter, the direction toward the inside of the plug connector main body 5 along the rotation axis direction is referred to as axially inward or simply inward, and the direction toward the outside of the plug connector main body 5 is referred to as axially outward or simply outward. ..

The axial orthogonal direction is a direction orthogonal to the insertion / extraction direction and the rotation axis direction. In the present embodiment, the cable 4 is pulled out from the plug connector main body 5 along the direction orthogonal to the axis. However, the cable 4 may be pulled out from the plug connector main body 5 along the insertion / removal direction or the rotation axis direction. The axially orthogonal direction includes the rear side as the direction in which the cable 4 is viewed from the plug connector 2 and the front side as the direction in which the plug connector 2 is viewed from the cable 4.

The above-mentioned insertion / removal direction, rotation axis direction, and axis orthogonal direction are defined mainly based on the configuration of the plug connector 2, but these directions are also used when explaining the configuration of the receptacle connector 3. Therefore, for example, the direction of the rotation axis in the receptacle connector 3 is interpreted as the direction in which the rotation axis 6C of the lever 6 included in the plug connector 2 fitted to the receptacle connector 3 extends.

(Plug connector 2)
Next, the plug connector 2 will be described with reference to FIGS. 4 and 5. The side sectional view shown in FIG. 5 relates to a sectional view of dividing one arm 33 of the lever 6 in the plate thickness direction.

As described above, the plug connector 2 is composed of the plug connector main body 5 and the lever 6.

(Plug connector 2: Plug connector body 5)
As shown in FIG. 4, the plug connector main body 5 includes a plurality of plug contacts 10, a plug contact holder 11, a plug housing 12, and a cable holder 13.

The plurality of plug contacts 10 are formed by punching and bending a metal plate made of copper or a copper alloy. The plurality of plug contacts 10 are held in a plug contact holder 11 made of an insulating resin, so that they are lined up in a row in the rotation axis direction at a predetermined pitch.

The plug housing 12 is made of an insulating resin and is formed in a box shape having a receptacle storage space 14 that opens downward. That is, the plug housing 12 has a front end plate portion 12A, a rear end plate portion 12B, two side plate portions 12C, and a top plate portion 12D. The front end plate portion 12A and the rear end plate portion 12B partition the receptacle accommodating space 14 in the direction orthogonal to the axis. The two side plate portions 12C partition the receptacle accommodating space 14 in the direction of the rotation axis. The top plate portion 12D partitions the receptacle accommodating space 14 in the insertion / removal direction.

The tip plate portion 12A has a tip inner surface 15 facing the receptacle accommodating space 14. The rear end plate portion 12B has a rear end inner surface 16 facing the receptacle accommodating space 14. The front end inner surface 15 and the rear end inner surface 16 are both planes orthogonal to the axis orthogonal direction, and face each other in the axis orthogonal direction. The side view of FIG. 5 shows a dichotomy line 17 that divides the volume of the receptacle accommodating space 14 in the direction orthogonal to the axis. Specifically, the dichotomous line 17 is located between the tip inner surface 15 and the rear end inner surface 16 in the axial orthogonal direction, and is located at the same distance from the tip inner surface 15 and the rear end inner surface 16 in the axial orthogonal direction. The dichotomy line 17 is a straight line extending in the insertion / extraction direction in the side view shown in FIG.

When at least one of the front end inner surface 15 and the rear end inner surface 16 is a curved surface, the dichotomy line 17 is defined based on the dichotomy surface that divides the volume of the receptacle accommodating space 14 in the direction orthogonal to the axis. To do. It is assumed that the dichotomized plane is a plane orthogonal to the axially orthogonal direction.

Returning to FIG. 4, the tip plate portion 12A is formed with a lever lock portion 20 for fixing the lever 6 pushed downward.

The rear end plate portion 12B is formed with a cable insertion hole 21 into which the end portion 4A of the cable 4 is inserted. The drawings of the plurality of covered electric wires included in the cable 4 are omitted.

A rotating shaft 22 for rotatably holding the lever 6 with respect to the plug housing 12 is formed on each side plate portion 12C. Each rotating shaft 22 is formed so as to project outward from each side plate portion 12C in a columnar shape. Each rotating shaft 22 has a rotating axis 23 as the central axis of the cylinder. The rotation axis 23 is the rotation axis 6C itself shown in FIGS. 1 to 3. As shown in FIG. 5, the rotation axis 23 of each rotation shaft 22 is arranged apart from the dichotomy line 17 and is arranged between the dichotomy line 17 and the rear end plate portion 12B. Further, the rotation axis 23 of each rotation shaft 22 is arranged closer to the top plate portion 12D.

Returning to FIG. 4, the cable holder 13 fixes the cable 4 inserted in the cable insertion hole 21 of the plug housing 12 so as to be immovable in the direction orthogonal to the axis.

(Plug connector 2: Lever 6)
Subsequently, as shown in FIG. 4, the lever 6 includes a lever body 30 and a lock spring 31.

The lever body 30 is composed of a lever base 32, two arms 33, and an operation unit 34.

The lever base 32 extends in the direction of the rotation axis.

Each arm 33 is formed so as to project from both ends of the lever base 32 in the rotation axis direction. Each arm 33 extends in a direction orthogonal to the direction of rotation axis. A bearing hole 35 into which each rotating shaft 22 is inserted is formed in each arm 33.

As described above, the lever body 30 is formed in a U shape that opens toward the rotation axis 23 by including the lever base 32 and the two arms 33.

The operation unit 34 is for facilitating the user who operates the lever type connector 1 to operate the lever 6, and is formed so as to project from the lever base 32. The operation unit 34 may be omitted. In this case, when the user operates the lever 6, the lever base 32 itself is used instead of the operation unit 34.

Hereinafter, each arm 33 will be described in detail. First, in FIG. 5, the “locking direction” and the “unlocking direction” are defined. The locking direction is the direction in which the lever 6 is rotated when the plug connector 2 is fitted to the receptacle connector 3. The unlocking direction is the direction opposite to the locking direction, and is the direction in which the lever 6 is rotated when the plug connector 2 is removed from the receptacle connector 3.

FIG. 5 shows the lever 6 in the fitted state of the lever type connector 1. In the fitted state of the lever type connector 1, the lever 6 is in a posture in which the operating portion 34 and the bearing hole 35 are at the same height in the insertion / removal direction as a result of being pushed down in the locking direction. Hereinafter, when each arm 33 is described, for convenience of explanation, in principle, the posture of the lever 6 in the fitted state of the lever type connector 1 is used as a reference.

As shown in FIG. 5, each arm 33 includes an arm body 40 and a plug lock portion 41. The arm body 40 is a portion extending along an axis orthogonal direction. The arm body 40 extends from the lever base 32 toward the bearing hole 35. The plug lock portion 41 is arranged below the arm main body 40, and is a portion that protrudes from the arm main body 40 in the locking direction. Therefore, the plug lock portion 41 is located below the rotation axis 23 in the fitted state of the lever type connector 1.

Subsequently, as shown in FIG. 5, the operation unit 34, the plug lock unit 41, the dichotomizing line 17, and the rotating axis 23 (rotating shaft 22, bearing hole 35) are arranged in the order of description in the direction orthogonal to the axis. Therefore, for example, the rotation axis 23 and the plug lock portion 41 are displaced in the axial orthogonal direction, and are arranged apart from each other in the axial orthogonal direction. The rotation axis 23 and the plug lock portion 41 are arranged so as to be opposite to each other with the dichotomy line 17 in the direction orthogonal to the axis. The rotation axis 23 is arranged on the side opposite to the operation unit 34 with the dichotomy line 17 in the direction orthogonal to the axis. The plug lock portion 41 is arranged between the operation portion 34 and the dichotomous line 17 in the direction orthogonal to the axis.

The arm body 40 has a plug first interference surface 42 (plug interference surface) and a retracted inclined surface 43. The plug first interference surface 42 and the retracted inclined surface 43 are smoothly connected to each other in the direction orthogonal to the axis, and both face downward. The plug first interference surface 42 is formed between the operation unit 34 and the rotation axis 23 in the direction orthogonal to the axis. The retracted inclined surface 43 is formed on the side opposite to the operation unit 34 with the rotation axis 23 in the direction orthogonal to the axis. The plug first interference surface 42 and the retracted inclined surface 43 are connected to each other directly below the rotation axis 23.

The plug first interference surface 42 is flat and faces the locking direction. In the present embodiment, the plug first interference surface 42 is orthogonal to the insertion / removal direction. The plug first interference surface 42 is formed so as to straddle the dichotomy line 17 in the direction orthogonal to the axis. That is, the dichotomy line 17 intersects the plug first interference surface 42.

The retracted inclined surface 43 has a curved surface shape that is convex in the direction away from the bearing hole 35, and extends from the plug first interference surface 42 in the locking direction.

The plug lock portion 41 has a plug second interference surface 44 and a lock execution surface 45. The plug second interference surface 44 and the lock execution surface 45 are connected to each other in the insertion / extraction direction, and both face rearward. Both the plug second interference surface 44 and the lock execution surface 45 are arranged between the operation unit 34 and the dichotomous line 17 in the direction orthogonal to the axis.

The plug second interference surface 44 is formed so as to extend downward from the front end of the plug first interference surface 42. Specifically, the plug second interference surface 44 is formed so as to be slightly inclined with respect to the dichotomy line 17 so as to go backward as it goes downward.

The lock execution surface 45 extends downward from the lower end of the plug second interference surface 44, and is formed by being curved in an arc shape so as to be convex rearward.

Returning to FIG. 4, the lock spring 31 is formed by punching and bending a metal plate, and is provided on the lever base 32. When the lever 6 is pushed down in the locking direction, the lock spring 31 engages with the lever locking portion 20 of the plug connector main body 5, thereby preventing the lever 6 from rotating in the unlocking direction. If the lock spring 31 itself is operated to release the locked state between the lock spring 31 and the lever lock portion 20, the lever 6 can be rotated in the unlocking direction.

(Receptacle connector 3)
Next, the receptacle connector 3 will be described with reference to FIGS. 6 and 7.

As shown in FIG. 6, the receptacle connector 3 includes a plurality of receptacle contacts 50, a receptacle contact holder 51, a receptacle main body 52, and a seal member 53.

The plurality of receptacle contacts 50 are formed by punching and bending a metal plate made of copper or a copper alloy. The plurality of receptacle contacts 50 are held in the receptacle contact holder 51 made of an insulating resin, so that the plurality of receptacle contacts 50 are arranged in two rows in the rotation axis direction at a predetermined pitch.

The receptacle body 52 is made of an aluminum alloy or a zinc alloy, and includes a receptacle base 54 (base), a receptacle housing 55, and two receptacle lock portions 56.

The receptacle base 54 is a flat plate whose thickness direction is parallel to the insertion / extraction direction, and has a holder insertion port 57.

The receptacle housing 55 is formed so as to extend upward from the peripheral edge of the holder insertion port 57 of the receptacle base 54 in a tubular shape. Then, the receptacle contact holder 51 is inserted into and held in the receptacle housing 55. A seal member mounting groove 58 to which the seal member 53 is mounted is formed on the outer peripheral surface 55A of the receptacle housing 55.

The two receptacle lock portions 56 are arranged so as to be opposite to each other with the receptacle housing 55 in the direction of the rotation axis. The two receptacle lock portions 56 are arranged apart from the receptacle housing 55 in the rotation axis direction. The two receptacle lock portions 56 have the same shape as each other.

Each receptacle lock portion 56 is formed so as to project upward from the receptacle base 54. As shown in FIG. 7, each receptacle lock portion 56 is formed line-symmetrically with respect to the above-mentioned dichotomy line 17. Each receptacle lock portion 56 is formed so as to expand in the direction orthogonal to the axis as it goes upward. Each receptacle lock portion 56 has a shape substantially like a wine glass. For convenience of explanation, the seal member 53 and the receptacle housing 55 are not drawn in FIG. 7.

Subsequently, with reference to FIG. 7, each receptacle lock portion 56 has a receptacle first interference surface 60 (receptacle interference surface) and two receptacle lock side surfaces 61.

The receptacle first interference surface 60 is a flat surface facing upward. In the present embodiment, the receptacle first interference surface 60 is orthogonal to the insertion / extraction direction. The receptacle first interference surface 60 extends in the direction orthogonal to the axis across the dichotomy line 17.

The two receptacle lock side surfaces 61 extend downward from both ends of the receptacle first interference surface 60 in the direction orthogonal to the axis, one facing forward and the other facing backward. That is, both of the two receptacle lock side surfaces 61 are oriented in the direction orthogonal to the axis. Each receptacle lock side surface 61 has a receptacle second interference surface 62 and a lock receiving curved surface 63.

The receptacle second interference surface 62 is planar and extends downward from the end portion of the receptacle first interference surface 60 in the direction orthogonal to the axis. The receptacle second interference surface 62 is inclined so as to approach the dichotomy line 17 as it goes downward.

The lock receiving curved surface 63 is formed below the receptacle second interference surface 62, and is formed to be curved in an arc shape so as to be convex toward the dichotomy line 17. Therefore, it can be mentioned that the lock receiving recess 64 defined by the lock receiving curved surface 63 is formed on each receptacle lock side surface 61. The lock receiving recess 64 is formed so as to be recessed toward the dichotomy line 17.

(Operation)
Next, the operation of the lever type connector 1 will be described with reference to FIGS. 8 to 10. In each figure, the servomotor 70 to which the receptacle connector 3 is attached is shown by a chain double-dashed line. For convenience of explanation, similarly to FIG. 5, FIGS. 8 to 10 show a cross section of one arm 33 of the lever 6 in the plate thickness direction.

FIG. 8 shows a facing state in which the plug connector 2 is opposed to the receptacle connector 3 in the insertion / removal direction in order to fit the plug connector 2 into the receptacle connector 3. As shown in FIG. 8, in this facing state, the lever 6 is held at an unlocked position where the operating portion 34 is located above the plug connector main body 5.

When the plug connector 2 is moved toward the receptacle connector 3 from this facing state, first, the plug housing 12 of the plug connector main body 5 of the plug connector 2 is seated on the seal member 53 of the receptacle connector 3. In this state, the lever 6 is rotated in the locking direction by pushing the operation unit 34 downward with a finger. Then, as shown in FIG. 9, the lock execution surface 45 of the plug lock portion 41 of the lever 6 of the plug connector 2 comes into contact with the receptacle second interference surface 62 of the receptacle lock portion 56 of the receptacle connector 3 to lock the lever 6. Further rotation in the direction is prevented.

Subsequently, the operation unit 34 is pushed downward with a finger. Then, since the rotation of the lever 6 in the locking direction is prevented, the force for pushing the operation unit 34 downward becomes the driving force for moving the plug connector 2 downward as it is. Due to this driving force, the plug connector 2 moves further downward with elastic deformation of the seal member 53. As a result, the receptacle housing 55 shown in FIG. 6 is housed in the receptacle housing space 14 shown in FIG. Returning to FIG. 9, when the plug connector 2 moves downward, the lock execution surface 45 of the plug lock portion 41 moves downward while being in contact with the receptacle lock side surface 61 of the receptacle lock portion 56. Here, since the receptacle lock side surface 61 is inclined downward so as to approach the dichotomy line 17, the lever 6 rotates slightly in the locking direction when the plug connector 2 moves downward.

Eventually, when the plug housing 12 of the plug connector 2 abuts against the receptacle housing 55 of the receptacle connector 3 in the insertion / removal direction, further downward movement of the plug connector 2 is prevented. At the same time, as shown in FIG. 10, the plug lock portion 41 is housed in the lock receiving recess 64. As a result, the receptacle lock portion 56 and the plug lock portion 41 are adjacent to each other in the order described in the downward direction, thereby preventing the plug connector 2 from being removed from the receptacle connector 3.

At this time, the lock spring 31 of the lever 6 shown in FIG. 4 engages with the lever lock portion 20 of the plug housing 12 to prevent the lever 6 from rotating further in the unlocking direction. As a result, the lever 6 is held at the lock position shown in FIG. By holding the lever 6 in the locked position in this way, the lever type connector 1 is put into the fitted state.

In this mating state, the plug first interference surface 42 and the receptacle first interference surface 60 face each other with a slight gap in the insertion / removal direction. Similarly, the plug second interference surface 44 and the receptacle second interference surface 62 face each other with a slight gap. Then, the lock execution surface 45 of the plug lock portion 41 is in contact with the lock receiving curved surface 63 of the receptacle lock portion 56. Here, due to physical interference between the plug lock portion 41 and the lock receiving recess 64, each arm 33 is elastically deformed in the direction in which the plug lock portion 41 moves away from the rotation axis 23. Due to the elastic restoring force corresponding to this elastic deformation, the lock execution surface 45 of the plug lock portion 41 is strongly pressed against the lock receiving curved surface 63 of the receptacle lock portion 56.

In the fitting state shown in FIG. 10, when the fitting posture of the plug connector 2 with respect to the receptacle connector 3 is tilted, the plug first interference surface 42 and the receptacle first interference surface 60 come into contact with each other, so that the fitting posture is further increased. Tilt is suppressed. Similarly, when the fitting posture of the plug connector 2 with respect to the receptacle connector 3 is tilted, the plug second interference surface 44 and the receptacle second interference surface 62 come into contact with each other, so that further tilting of the fitting posture is suppressed. .. Therefore, for example, even if the contact portion between the plug connector 2 and the receptacle connector 3 is worn due to vibration and the play between the plug connector 2 and the receptacle connector 3 becomes large, the receptacle connector of the plug connector 2 can be configured by the above configuration. It becomes possible to continuously maintain a stable fitting posture with respect to 3.

In order to remove the plug connector 2 from the receptacle connector 3, the lock spring 31 of the lever 6 shown in FIG. 4 is operated to release the engagement state between the lock spring 31 and the lever lock portion 20, and the lever 6 is released. It may be rotated in the unlock direction. As a result, the plug lock portion 41 shown in FIG. 10 is pulled out from the lock receiving recess 64, so that the plug connector 2 can be pulled out upward from the receptacle connector 3.

Although the preferred embodiment of the present invention has been described above, the above-described embodiment has the following features.

As shown in FIGS. 1 to 7, the lever type connector 1 includes a plug connector main body 5 and a lever 6 rotatably supported by the plug connector main body 5 and having a plug lock portion 41 and an operation portion 34. The plug connector 2 and the receptacle connector 3 having the receptacle lock portion 56 are provided. As shown in FIG. 10, by operating the operating portion 34 of the lever 6, the receptacle lock portion 56 and the plug lock portion 41 are adjacent to each other in the order described below, whereby the plug connector 2 is removed from the receptacle connector 3. Is prevented. The lever 6 has a flat plug first interference surface 42 (plug interference surface). The receptacle connector 3 has a flat receptacle first interference surface 60 (receptacle interference surface). In the mated state in which the plug connector 2 and the receptacle connector 3 are fitted, the plug first interference surface 42 and the receptacle first interference surface 60 are arranged so as to face each other and in the axial direction of the rotation axis 23 of the lever 6. When viewed along the line, it is arranged between the plug lock portion 41 and the rotation axis 23 of the lever 6. When viewed along the rotation axis direction in the fitted state of the lever type connector 1, the rotation axis 23 of the lever 6 is operated with a dichotomy line 17 that bisects the receptacle accommodating space 14 of the plug connector body 5 in the direction orthogonal to the axis. It is arranged on the opposite side of the portion 34. When the fitting posture of the plug connector 2 with respect to the receptacle connector 3 is tilted, the plug first interference surface 42 and the receptacle first interference surface 60 come into contact with each other, so that the further tilting of the fitting posture is suppressed. According to the above configuration, the plug first interference surface 42 and the receptacle first interference surface 60 can be largely secured as compared with the case where the rotation axis 23 is arranged on the dichotomy line 17, so that the plug first interference surface 42 can be secured. In addition, the effect of suppressing the inclination of the fitting posture by the receptacle first interference surface 60 is realized at a high level.

Further, in the fitted state of the lever type connector 1, when viewed along the direction of the rotation axis, the plug lock portion 41 and the rotation axis 23 of the lever 6 are displaced in the direction orthogonal to the axis. Specifically, in the fitted state of the lever type connector 1, the plug lock portion 41 is arranged between the dichotomies 17 and the operation portion 34 in the direction orthogonal to the axis when viewed along the rotation axis direction. According to the above configuration, the plug first interference surface 42 of the lever 6 can cover the receptacle first interference surface 60 of the receptacle connector 3 over a wide area, so that the plug first interference surface 42 and the receptacle first interference surface 60 The effect of suppressing the inclination of the mating posture is realized at a higher level.

Further, in the fitted state of the lever type connector 1, the plug first interference surface 42 and the receptacle first interference surface 60 are arranged so as to be orthogonal to the fitting direction.

Further, as shown in FIG. 10, in the fitted state of the lever type connector 1, when viewed along the rotation axis direction, the plug first interference surface 42 and the receptacle first interference surface 60 are the plug lock portion 41 and the lever 6. It is arranged so as to intersect the straight line P connecting the rotation axis 23 of the above.

Further, in the fitted state of the lever type connector 1, when viewed along the rotation axis direction, the receptacle lock portion 56 is line-symmetrical with respect to the dichotomizing line 17.
