Technical Field

The application relates to a lever type connector.

Background

Document 1 (japanese patent laid-open No. 2017-168391) discloses a lever type connector 100 using a cam mechanism as shown in fig. 11 of the present application. That is, the angular cylindrical housing 101 is rotatably supported by the lever 103 having the cam groove 102. A cam follower 106 that can be inserted into the cam groove 102 is formed in the counterpart housing 105 that fits into the fitting space 104 of the housing 101.

Detailed Description

Hereinafter, a preferred embodiment of the present application will be described with reference to fig. 1 to 10.

Fig. 1 shows a fitted state of the lever-type connector 1, and fig. 2 and 3 show a state before the lever-type connector 1 is fitted. As shown in fig. 1 to 3, the lever connector 1 includes a plug connector 2 and a receptacle connector 3.

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

The receptacle connector 3 is to be attached to an outer wall surface of a servomotor, not shown.

By fitting the plug connector 2 to the receptacle connector 3, the plurality of conductors housed in the cable 4 are electrically connected to the control board of the servomotor.

The attachment object of the lever connector 1 is not limited to a servomotor, and may be any of various electronic devices including a motor other than a servomotor and a rotation detector.

(definition of direction)

Here, referring to fig. 1 to 3, the "insertion/extraction direction" and the "rotation axis" and the "axis orthogonal direction (orthogonal direction") are defined. The insertion and extraction directions, the rotation axial direction and the axial orthogonal direction are mutually orthogonal.

The insertion/extraction direction is a direction in which the plug connector 2 is inserted/extracted into/from the receptacle connector 3. The insertion and removal direction includes a lower direction as the fitting direction and an upper direction as the removal direction. The lower part 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. The terms below and above are words for convenience of description, and are not intended to limit the form of the lever-type connector 1 when in use.

The rotational axis is the extending direction of the rotational axis 6C of the lever 6, which lever 6 is rotatably supported to the plug connector body 5. Hereinafter, a direction along the rotational axis toward the inside of the plug connector body 5 will be referred to as an axially inward direction or a single inward direction, and a direction toward the outside of the plug connector body 5 will be referred to as an axially outward direction or a single outward direction.

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

Although the above-described insertion/extraction direction, rotation axis direction, and axis orthogonal direction are mainly defined based on the structure of the plug connector 2, these directions are also used in explaining the structure of the receptacle connector 3. Thus, taking the rotational axis of the receptacle connector 3 as an example, it can be interpreted as the direction in which the rotational axis 6C of the lever 6 extends, the lever 6 having the plug connector 2 fitted to the receptacle connector 3.

(plug connector 2)

Next, the plug connector 2 will be described with reference to fig. 4 and 5. The side cross-sectional view shown in fig. 5 is a cross-section of one of the arms 33 of the lever 6 divided into two in the plate thickness direction.

As described above, the plug connector 2 is constituted by the plug connector body 5 and the lever 6.

(plug connector 2: plug connector body 5)

As shown in fig. 4, the plug connector body 5 includes: a plurality of plug contacts 10, a plug contact carrier 11, a plug housing 12, and a cable carrier 13.

The plurality of plug contacts 10 are formed by punching and bending a metal plate made of copper or copper alloy. The plurality of plug contacts 10 are held by the plug contact holder 11 made of insulating resin, and are aligned in a row in the rotational axis direction at predetermined intervals.

The plug housing 12 is made of insulating resin, and is formed in a box shape having a socket housing space 14 opened at a lower side. That is, the plug housing 12 has: a front end plate 12A, a rear end plate 12B, two side plates 12C, and a top plate 12D. The front end plate portion 12A and the rear end plate portion 12B define a socket housing space 14 in the axial direction. The two side plate portions 12C define a receptacle accommodating space 14 in the rotational axis direction. The top plate 12D defines a socket housing space 14 in the insertion/removal direction.

The front end plate portion 12A has a front end inner surface 15 facing the receptacle housing space 14. The rear end plate portion 12B has a rear end inner face 16 facing the receptacle housing space 14. The front end inner surface 15 and the rear end inner surface 16 are planes orthogonal to the axial direction and face each other in the axial direction. In the side view of fig. 5, a bisector 17 is shown that divides the volume of the receptacle housing space 14 into two parts in the axis orthogonal direction. More specifically, the center line 17 is located between the front end inner surface 15 and the rear end inner surface 16 in the axial direction and is located at an equal distance from the front end inner surface 15 and the rear end inner surface 16 in the axial direction. In the side view shown in fig. 5, the middle split line 17 is a straight line extending in the insertion and extraction direction.

When at least one of the front end inner surface 15 and the rear end inner surface 16 is a curved surface, the bisector 17 is defined by a bisector that divides the volume of the receptacle housing space 14 into two in the axial direction. The bisector is a plane orthogonal to the axial orthogonal direction.

Returning to fig. 4, in the front end plate portion 12A, a lever locking portion 20 for fixing the lever 6 by being pressed downward is formed.

In the rear end plate portion 12B, a cable insertion hole 21 into which the end portion 4A of the cable 4 is inserted is formed. In addition, the description of the plurality of covered wires included in the cable 4 is omitted.

In each side plate portion 12C, a rotation shaft 22 for rotatably holding the lever 6 with respect to the plug housing 12 is formed. Each rotation shaft 22 is formed to protrude outward from each side plate 12C in a columnar shape. Each rotation shaft 22 has a rotation axis 23 as a cylindrical central axis. This rotation axis 23 is the rotation axis 6C shown in fig. 1 to 3. As shown in fig. 5, the rotation axis 23 of each rotation shaft 22 is disposed away from the intermediate line 17, and is disposed between the intermediate line 17 and the rear end plate portion 12B. The rotation axis 23 of each rotation shaft 22 is disposed near the top plate 12D.

Returning to fig. 4, the cable bracket 13 fixes the cable 4 inserted into the cable insertion hole 21 of the plug housing 12 so as not to move in the axial orthogonal direction.

(plug connector 2: rod 6)

As further 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 operating portion 34.

The lever base 32 extends in the rotational axial direction.

Each arm 33 is formed to protrude from both ends of the lever base 32 in the rotational axis direction. Each arm 33 extends in a direction orthogonal to the rotational axis. In each arm 33, a bearing hole 35 into which each rotation shaft 22 is inserted is formed.

In this way, the lever body 30 is formed in a U-shape opening toward the rotation axis 23 by including the lever base 32 and the two arms 33.

The operation portion 34 is for making it easy for a user operating the lever connector 1 to operate the lever 6, and is formed to protrude from the lever base 32. In addition, the operation unit 34 may be omitted. In this case, the lever base 32 is used as a substitute for the operating portion 34 when the user is operating the lever 6.

The respective arms 33 will be described in detail below. First, in fig. 5, a "locking direction" and an "unlocking direction" are defined. The locking direction is a direction in which the lever 6 is rotated when the plug connector 2 is fitted to the receptacle connector 3. The unlocking direction is a direction opposite to the locking direction, and is a direction in which the lever 6 is rotated when the plug connector 2 is pulled out of the receptacle connector 3.

Fig. 5 shows the lever 6 in the fitted state of the lever connector 1. In the fitted state of the lever connector 1, the lever 6 is in the same height in the insertion/removal direction as a result of the lever being pushed down in the locking direction, and the operating portion 34 and the bearing hole 35 are in the same height. In the following, for convenience of explanation, the lever 6 shape in the fitted state of the lever connector 1 is basically used as a reference for explanation of the respective arms 33.

As shown in fig. 5, each arm 33 includes: arm body 40, and plug locking portion 41. The arm body 40 is a portion extending in the axis orthogonal direction. The arm body 40 extends from the lever base 32 toward the bearing hole 35. The plug locking portion 41 is disposed below the arm body 40 and is a portion protruding from the arm body 40 in the locking direction. Therefore, in the fitted state of the lever-type connector 1, the plug locking portion 41 is located further below the rotation axis 23.

As further shown in fig. 5, the operation portion 34, the plug locking portion 41, the split line 17, and the rotation axis 23 (the rotation shaft 22, the bearing hole 35) are arranged in this order in the axis orthogonal direction. Therefore, the rotation axis 23 and the plug lock portion 41 are disposed apart from each other in the axial direction, with positional deviation in the axial direction being assumed as an example. The rotation axis 23 and the plug lock portion 41 are disposed on opposite sides in the axial orthogonal direction so as to sandwich the center line 17. The rotation axis 23 is disposed on the opposite side of the operation portion 34 in the axis orthogonal direction so as to sandwich the center line 17. The plug lock portion 41 is disposed between the operation portion 34 and the intermediate line 17 in the axis orthogonal direction.

The arm body 40 has: a plug first interference surface 42 (plug interference surface), and a retreat inclined surface 43. The plug first interference surface 42 and the escape inclined surface 43 are continuous and smooth in the axial direction, and both face downward. The plug first interference surface 42 is formed between the operation portion 34 and the rotation axis 23 in the shaft orthogonal direction. The retreat inclined surface 43 is formed on the opposite side of the operation portion 34 in the axial direction so as to sandwich the rotation axis 23. The plug first interference surface 42 and the escape inclined surface 43 are connected to each other directly below the rotation axis 23.

The plug first interference surface 42 is planar and faces in the locking direction. In the present embodiment, the plug first interference surface 42 is orthogonal to the insertion and extraction direction. The plug first interference surface 42 is formed to cross the median 17 in an axially orthogonal direction. That is, the middling line 17 intersects the plug first interference surface 42.

The escape inclined surface 43 is curved and extends in the locking direction from the plug first interference surface 42.

The plug lock portion 41 includes: a plug second interference surface 44, and a lock execution surface 45. The plug second interference surface 44 and the lock engagement surface 45 are continuous with each other in the insertion and removal direction and both face rearward. The plug second interference surface 44 and the lock execution surface 45 are disposed between the operation portion 34 and the center line 17 in the axial direction.

The plug second interference surface 44 is formed to extend downward from the front end of the plug first interference surface 42. More specifically, the plug second interference surface 44 is formed to be slightly inclined rearward with respect to the center line 17 as going downward.

The lock engagement surface 45 extends downward from the lower end of the plug second interference surface 44, and is curved in an arc shape so as to protrude 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 pressed down in the lock direction, the lock spring 31 engages with the lever lock portion 20 of the plug connector body 5, thereby preventing the lever 6 from rotating in the unlock direction. Further, if the locking spring 31 itself is operated to release the locked state of the locking spring 31 and the lever locking portion 20, the lever 6 is allowed to rotate in the unlocking direction.

(receptacle connector 3)

Next, the receptacle connector 3 will be described with reference to fig. 6 and 7.

As shown in fig. 6, the receptacle connector 3 includes: a plurality of socket contacts 50, a socket contact carrier 51, a socket body 52, and a sealing member 53.

The plurality of socket contacts 50 are formed by punching and bending a metal plate made of copper or copper alloy. The plurality of socket contacts 50 are held by the socket contact brackets 51 made of insulating resin, and are arranged in two rows at a predetermined pitch in the rotational axis direction.

The socket body 52 is made of an aluminum alloy or a lead alloy, and includes: a socket base 54 (base), a socket housing 55, and two socket locking parts 56.

The socket base 54 is a flat plate having a plate thickness direction parallel to the insertion and extraction direction, and has a bracket insertion port 57.

The socket housing 55 is formed to extend upward in a tubular shape from the periphery of the bracket insertion port 57 of the socket base 54. Then, the socket housing 55 is inserted with the socket contact holder 51 held therein. In the outer peripheral surface 55A of the receptacle housing 55, a seal member mounting groove 58 is formed in which the seal member 53 is mounted.

The two receptacle lock portions 56 are disposed so as to sandwich the receptacle housing 55 in the rotational axis direction and so as to be opposite to each other. The two receptacle lock portions 56 are disposed away from the receptacle housing 55 in the rotational axial direction. The two socket locking parts 56 are identical in shape to each other.

Each of the socket locking portions 56 is formed to protrude upward from the socket base 54. As shown in fig. 7, the receptacle lock portions 56 are formed to be line-symmetrical to the center line 17. Each socket lock portion 56 is formed so as to be wider in the axial orthogonal direction as going upward. Each socket locking portion 56 has a general shape like a red wine glass. For convenience of explanation, in fig. 7, the seal member 53 and the receptacle housing 55 are not depicted.

With continued reference to fig. 7, each receptacle lock portion 56 has: a socket first interference surface 60 (socket interference surface), and two socket locking sides 61.

The receptacle first interference surface 60 is planar and faces upward. In the present embodiment, the receptacle first interference surface 60 is orthogonal to the insertion and extraction direction. The receptacle first interference surface 60 spans the median line 17 and extends in an axially orthogonal direction.

The two socket locking side surfaces 61 extend downward from both ends of the socket first interference surface 60 in the axis orthogonal direction, with one of them being forward and the other being rearward. That is, both receptacle lock sides 61 face in the axis orthogonal direction. Each receptacle lock side 61 has: a receptacle second interference surface 62, and a lock receiving curved surface 63.

The socket second interference surface 62 is planar and extends downward from an end of the socket first interference surface 60 in the axial direction. The receptacle second interference surface 62 is inclined downward so as to approach the center line 17.

The lock receiving curved surface 63 is formed below the socket second interference surface 62, and is curved in an arc shape so that the intermediate line 17 is convex in the conventional art. Accordingly, it can be said that in each receptacle lock side surface 61, a lock receiving recess 64 defined by the lock receiving curved surface 63 is formed. The lock receiving recess 64 is formed concave toward the center line 17.

(operation)

Next, the operation of the lever-type connector 1 will be described with reference to fig. 8 to 10. In each figure, the servomotor 70 to which the receptacle connector 3 is attached is shown as a two-dot chain line. For convenience of explanation, fig. 8 to 10 show a cross section of one arm 33 of the lever 6 divided into two in the plate thickness direction as in fig. 5.

Fig. 8 shows a state in which the plug connector 2 and the receptacle connector 3 are opposed to each other in the insertion/removal direction in order to fit the plug connector 2 to the receptacle connector 3. As shown in fig. 8, in this opposing state, the lever 6 is maintained in the unlock position, which is a position where the operating portion 34 is located above the plug connector body 5.

When the plug connector 2 is moved toward the receptacle connector 3 from this opposing state, first, the plug housing 12 of the plug connector 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 lock direction by pressing the operation portion 34 downward with a finger. As described above, 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 contacts the socket second interference surface 62 of the socket lock portion 56 of the socket connector 3, thereby preventing the lever 6 from rotating further in the locking direction.

Continuing, the operation unit 34 is pressed downward by a finger. In this way, since the lever 6 is prevented from rotating in the locking direction, the force that presses the operation portion 34 downward becomes a driving force that directly moves the plug connector 2 downward. By this driving force, the plug connector 2 moves further downward with elastic deformation of the seal member 53. Thereby, the socket housing 55 shown in fig. 6 is accommodated in the socket accommodating space 14 shown in fig. 4. 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 contacting the receptacle lock side surface 61 of the receptacle lock portion 56. Here, since the receptacle lock side 61 is inclined so as to be closer to the center line 17 further down, the lever 6 slightly rotates in the lock direction when the plug connector 2 moves down.

Finally, when the plug housing 12 of the plug connector 2 is brought into contact with the receptacle housing 55 of the receptacle connector 3 in the insertion/extraction direction, the plug connector 2 is prevented from moving further downward. At the same time, as shown in fig. 10, the plug locking portion 41 is accommodated in the lock receiving recess 64. Thereby, the receptacle lock portion 56 and the plug lock portion 41 are adjacent in this order, and the plug connector 2 is prevented from being pulled out of the receptacle connector 3.

At this time, the lock spring 31 of the lever 6 shown in fig. 4 is engaged with the lever lock portion 20 of the plug housing 12, thereby preventing the lever 6 from rotating further in the unlocking direction. Thereby, the lever 6 is maintained in the locked position shown in fig. 10. The lever connector 1 is brought into a fitted state by maintaining the lever 6 in the lock position.

In this fitted state, the plug first interference surface 42 and the receptacle first interference surface 60 face each other with a slight gap therebetween in the insertion/extraction direction. Similarly, the plug second interference surface 44 and the receptacle second interference surface 62 are opposed to each other with a slight gap therebetween. The lock execution surface 45 of the plug lock 41 is in contact with the lock receiving curved surface 63 of the receptacle lock 56. Here, the plug locking portion 41 of each arm 33 is elastically deformed in a direction away from the rotation axis 23 by physical interference of the plug locking portion 41 and the lock receiving recess 64. The lock execution surface 45 of the plug lock 41 is strongly pressed against the lock receiving curved surface 63 of the receptacle lock 56 by the restoring force corresponding to the elastic deformation.

In the fitted state shown in fig. 10, when the plug connector 2 is tilted with respect to the fitted state of the receptacle connector 3, the plug first interference surface 42 and the receptacle first interference surface 60 are brought into contact with each other, thereby preventing the fitted state from being tilted further. Similarly, when the plug connector 2 is tilted with respect to the fitting form of the receptacle connector 3, the plug second interference surface 44 and the receptacle second interference surface 62 are brought into contact with each other, thereby preventing the fitting form from being tilted even more. Therefore, even when the contact loss of the plug connector 2 and the receptacle connector 3 due to vibration or the damage between the plug connector 2 and the receptacle connector 3 becomes large, for example, the above-described structure can continue to maintain the stable fitting state of the plug connector 2 to the receptacle connector 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 between the lock spring 31 and the lever lock portion 20, and the lever 6 is rotated in the unlocking direction. As a result, the plug lock portion 41 shown in fig. 10 is pulled out from the lock receiving recess 64, and thus the plug connector 2 can be pulled out upward from the receptacle connector 3.

The preferred embodiments of the present application are described above, and the above embodiments have the following features.

As shown in fig. 1 to 7, the lever type connector 1 includes: the plug connector 2 includes a plug connector body 5 and a lever 6, the lever 6 being rotatably supported by the plug connector body 5 and having a plug lock portion 41 and an operation portion 34; and a receptacle connector 3 having a receptacle lock portion 56. As shown in fig. 10, the plug connector 2 is prevented from being pulled out of the receptacle connector 3 by the operation portion 34 of the operation lever 6 and the receptacle lock portion 56 and the plug lock portion 41 being adjacent in this order of description in the conventional downward direction. The lever 6 has a planar plug first interference surface 42 (plug interference surface). The receptacle connector 3 has a planar receptacle first interference surface 60 (receptacle interference surface). In the fitted 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 disposed so as to face each other, and are disposed between the plug lock portion 41 and the rotation axis 23 of the lever 6 as viewed in the axial direction of the rotation axis 23 of the lever 6. In the fitted state of the lever connector 1, the rotation axis 23 of the lever 6 is arranged on the opposite side of the operation portion 34 so as to sandwich the intermediate line 17, as viewed in the rotation axis direction, and the intermediate line 17 divides the receptacle housing space 14 of the plug connector body 5 into two parts in the orthogonal direction. When the plug connector 2 is tilted with respect to the mating pattern of the receptacle connector 3, the plug first interference surface 42 and the receptacle first interference surface 60 are brought into contact with each other, thereby preventing the mating pattern from being tilted. According to the above configuration, the plug first interference surface 42 and the receptacle first interference surface 60 can be ensured to a large extent, as compared with the case where the rotation axis 23 is arranged on the center line 17, and therefore, the effect of avoiding the distortion of the fitting pattern due to the plug first interference surface 42 and the receptacle first interference surface 60 can be achieved to a high degree.

In the fitted state of the lever-type connector 1, the plug lock portion 41 and the rotation axis 23 of the lever 6 are displaced in the axial direction when viewed in the rotation axis direction. Specifically, in the fitted state of the lever-type connector 1, the plug lock portion 41 is arranged between the intermediate line 17 and the operation portion 34 as viewed in the rotational axis direction. According to the above configuration, since the plug first interference surface 42 of the lever 6 can cover the socket first interference surface 60 of the socket connector 3 over a wide area, the effect of preventing the fitting pattern from being distorted due to the plug first interference surface 42 and the socket first interference surface 60 can be further achieved.

In the mated state of the lever-type connector 1, the plug first interference surface 42 and the receptacle first interference surface 60 are disposed so as to be orthogonal to the mating direction.

In addition, as shown in fig. 10, 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 intersect a straight line P connecting the plug locking portion 41 and the rotation axis 23 of the lever 6, as viewed in the rotation axis direction.

In the fitted state of the lever-type connector 1, the receptacle lock portion 56 is line-symmetrical to the center line 17 as viewed in the rotational axis direction. According to the above configuration, the plug connector 2 can be fitted to the receptacle connector 3 by reversing the direction of the plug connector in the axis orthogonal direction.

As shown in fig. 6 and 7, the receptacle connector 3 further includes: a socket base 54 (base), and a socket housing 55, the socket base 54 having a plate thickness direction parallel to the lower side, the socket housing 55 extending upward from the socket base 54 in a tubular shape. The socket locking portion 56 is formed to protrude upward from the socket base 54.

As shown in fig. 7, the socket lock portion 56 has two socket lock side surfaces 61 facing in the axial direction perpendicular to the axis, as viewed in the rotational axis direction. In each receptacle lock side 61, a lock receiving recess 64 that receives the plug lock portion 41 is formed.

The socket lock portion 56 is formed so as to be wider in the axial direction perpendicular to the axis as seen in the rotational axis direction.

Further, japanese patent laid-open No. 2018-206517 discloses a diamond-type locking member. However, since the cam follower of patent document 1 is a cylinder, it is a common technical knowledge, and therefore, the cam follower cannot be replaced with the locking member.

The present application claims priority based on japanese patent application publication No. 2019-160346, filed on 3 of 9 in 2019, and the entire contents of said patent application are incorporated herein by reference.
