Detailed ways

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

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

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

The socket connector 3 is installed on the outer wall surface of the servo motor (not shown).

And by fitting the plug connector 2 into the receptacle connector 3, the plurality of conductors housed in the cable 4 are electrically connected to the control board of the servo motor.

In addition, the mounting object of the rod connector 1 is not limited to a fixed servo motor, but may also include motors other than servo motors or various electronic devices including a rotation detector.

(Definition of direction)

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

The insertion and extraction direction is the direction in which the plug connector 2 is inserted into and extracted from the socket connector 3 . The insertion and extraction direction includes the downward direction as the fitting direction and the upper direction as the extraction direction. The lower part shows the direction in which the plug connector 2 approaches the receptacle connector 3 when the plug connector 2 is fitted into the receptacle connector 3 . Above is the opposite direction of below. In addition, the terms below and above are merely terms for convenience of explanation and are not used to limit the form of the lever connector 1 when used.

The rotation axis direction is the extension direction of the rotation axis 6C of the rod 6 which is rotatably supported on the plug connector body 5 . Hereinafter, the direction toward the inside of the plug connector body 5 along the rotation axis will be referred to as the axial inward direction, or simply the inward direction, and the direction toward the outside of the plug connector body 5 will be referred to as the axial outward direction. Foreign side.

The axis orthogonal direction is the direction orthogonal to the insertion and extraction direction and the rotation axis direction. In this embodiment, the cable 4 is drawn out from the plug connector body 5 in the direction orthogonal to the axis. However, the cable 4 can also be led out from the plug connector body 5 along the plugging and unplugging direction or the rotation axis direction. The axis-orthogonal direction includes the rear as the direction in which the cable 4 is viewed from the plug connector 2 and the front as the direction in which the plug connector 2 is viewed from the cable 4 .

Although the above-mentioned insertion and extraction directions, rotation axis directions, and axis-orthogonal directions are mainly defined based on the structure of the plug connector 2 , these directions will also be used when describing the structure of the socket connector 3 . Therefore, taking the rotation axis direction of the socket connector 3 as an example, it can be interpreted as the direction in which the rotation axis 6C of the rod 6 having the plug connector 2 fitted into the socket connector 3 extends.

(Plug connector 2)

Next, the plug connector 2 will be described with reference to FIGS. 4 and 5 . In addition, the side cross-sectional view shown in FIG. 5 is a cross-section obtained by dividing one arm 33 of the lever 6 into two parts in the thickness direction.

As mentioned before, the plug connector 2 is composed of a plug connector body 5 and a stem 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 bracket 11 , a plug housing 12 , and a cable bracket 13 .

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

The plug housing 12 is made of an insulating resin and is formed in a box shape having a socket accommodating space 14 open below. That is, the plug housing 12 has a front end plate part 12A, a rear end plate part 12B, two side plate parts 12C, and a top plate part 12D. The front end plate portion 12A and the rear end plate portion 12B define the socket receiving space 14 in the axially orthogonal direction. The two side plate portions 12C define a socket receiving space 14 in the rotation axis direction. The top plate portion 12D defines a socket receiving space 14 in the insertion and extraction direction.

The front end plate portion 12A has a front end inner surface 15 facing the socket receiving space 14 . The rear end plate portion 12B has a rear end inner surface 16 facing the socket receiving space 14 . The front end inner surface 15 and the rear end inner surface 16 are both planes orthogonal to the axial orthogonal direction, and are opposite to each other in the axial orthogonal direction. In the side view of FIG. 5 , a center line 17 is shown that divides the volume of the socket receiving space 14 into two parts in the axis-orthogonal direction. Specifically, the center line 17 is located between the front end inner surface 15 and the rear end inner surface 16 in the axis-orthogonal direction, and is equidistant from the front end inner surface 15 and the rear end inner surface 16 in the axis-orthogonal direction. In the side view shown in FIG. 5 , the center line 17 is a straight line extending in the insertion and extraction direction.

In addition, when at least one of the front end inner surface 15 and the rear end inner surface 16 is a curved surface, the center line 17 is defined by a center line that divides the volume of the socket accommodation space 14 into two parts in the axis-orthogonal direction. In addition, the midsection plane is a plane orthogonal to the direction orthogonal to the axis.

Returning to FIG. 4 , the front end plate portion 12A is formed with a lever lock portion 20 for pressing downward to fix the lever 6 .

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. In addition, description of the plurality of covered electric wires included in the cable 4 is omitted.

A rotation shaft 22 for rotatably holding the rod 6 to the plug housing 12 is formed in each side plate portion 12C. Each rotation shaft 22 is formed in a cylindrical shape protruding outward from each side plate portion 12C. Each rotation shaft 22 has a rotation axis 23 as the central axis of the cylinder. This rotation axis 23 is the rotation axis 6C shown in FIGS. 1 to 3 . As shown in FIG. 5 , the rotation axis 23 of each rotation shaft 22 is arranged away from the center line 17 and between the center line 17 and the rear end plate portion 12B. Moreover, the rotation axis 23 of each rotation shaft 22 is arrange|positioned close to the top plate part 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 axis-orthogonal direction.

(Plug connector 2: Rod 6)

As shown in FIG. 4 , the lever 6 is configured to include 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 part 34.

The rod base 32 extends in the rotation axis direction.

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

In this manner, the lever body 30 includes the lever base 32 and the two arms 33 , thereby forming a U-shape opening toward the rotation axis 23 .

The operating portion 34 is used to allow the user of the lever type connector 1 to easily operate the lever 6 , and is formed to protrude from the lever base 32 . In addition, the operation part 34 may be omitted. In this case, when the user operates the lever 6 , the lever base 32 serves as a substitute for the operating part 34 .

Each arm 33 will be described in detail below. First, in Figure 5, "locking direction" and "unlocking direction" are defined. The locking direction is the direction in which the lever 6 is rotated when the plug connector 2 is fitted into the receptacle connector 3 . The unlocking direction is the opposite direction to the locking direction, and is the direction in which the lever 6 is rotated when the plug connector 2 is pulled out from the socket connector 3 .

In FIG. 5 , the lever 6 is shown in the fitted state of the lever connector 1 . When the lever 6 in the mated state of the lever connector 1 is pressed in the locking direction, the operating portion 34 and the bearing hole 35 have the same height in the insertion and extraction direction. When describing each arm 33 below, for convenience of explanation, the form of the lever 6 in the mated state of the lever connector 1 will be used as a standard in principle.

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 in the direction orthogonal to the axis. The arm body 40 extends from the rod base 32 toward the bearing hole 35 . The plug lock 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 mated state of the lever connector 1 , the plug lock portion 41 is located below the rotation axis 23 .

Continuing as shown in FIG. 5 , in the axis-orthogonal direction, the operating part 34 , the plug locking part 41 , the center line 17 , and the rotation axis 23 (rotation shaft 22 , bearing hole 35 ) are arranged in this order. Therefore, taking the rotation axis 23 and the plug lock portion 41 as an example, there is a positional deviation in the axis-orthogonal direction, and they are arranged away from each other in the axis-orthogonal direction. The rotation axis 23 and the plug lock portion 41 are arranged on opposite sides in the axis-orthogonal direction so as to sandwich the center line 17 . The rotation axis 23 is arranged on the opposite side to the operation portion 34 in the axis-orthogonal direction so as to sandwich the center line 17 . The plug locking portion 41 is arranged between the operating portion 34 and the center 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 first interference surface 42 and the retraction inclined surface 43 of the plug are smoothly continuous with each other in the axis-orthogonal direction, and both face downward. The plug first interference surface 42 is formed between the operating portion 34 and the rotation axis 23 in the axis-orthogonal direction. The retraction inclined surface 43 is formed on the opposite side to the operation part 34 in the axis-orthogonal 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 first interference surface 42 of the plug is planar and faces the locking direction. In this embodiment, the first interference surface 42 of the plug is orthogonal to the insertion and extraction direction. The plug first interference surface 42 is formed across the center line 17 in the axis-orthogonal direction. That is, the center line 17 intersects the first interference surface 42 of the plug.

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

The plug locking portion 41 has a plug second interference surface 44 and a locking implementation surface 45 . The second interference surface 44 and the locking implementation surface 45 of the plug are continuous with each other in the insertion and extraction direction and both face rearward. The plug second interference surface 44 and the locking execution surface 45 are both arranged between the operating portion 34 and the center line 17 in the axis-orthogonal direction.

The plug second interference surface 44 is formed to extend downward from the front end of the plug first interference surface 42 . Specifically, the plug second interference surface 44 is formed to be slightly inclined toward the rear of the center line 17 as it goes downward.

The locking execution surface 45 extends downward from the lower end of the plug second interference surface 44 and is formed in an arc shape so as to bulge toward the rear.

Returning to FIG. 4 , the lock spring 31 is formed by punching and bending a metal plate, and is provided on the rod base 32 . When the lever 6 is pressed down in the locking direction, the locking spring 31 engages with the lever locking portion 20 of the plug connector body 5, thereby preventing the lever 6 from rotating in the unlocking direction. In addition, 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 is allowed to rotate in the unlocking direction.

(socket connector 3)

Next, the socket connector 3 will be described with reference to FIGS. 6 and 7 .

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

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

The socket body 52 is made of aluminum alloy or 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 with a thickness direction parallel to the plug-in and pull-out direction, and has a bracket insertion opening 57 .

The socket housing 55 is formed in a cylindrical shape extending upward from the peripheral edge of the bracket insertion opening 57 of the socket base 54 . Furthermore, the socket contact bracket 51 is inserted and held into the socket housing 55 . A sealing member mounting groove 58 for mounting the sealing member 53 is formed in the outer peripheral surface 55A of the socket housing 55 .

The two socket locking parts 56 sandwich the socket housing 55 in the rotation axis direction and are arranged on opposite sides to each other. The two socket locking parts 56 are arranged away from the socket housing 55 in the rotation axis direction. The two socket locking parts 56 have the same shape as each other.

Each socket lock portion 56 is formed to protrude upward from the socket base 54 . As shown in FIG. 7 , each socket locking portion 56 is formed to be line-symmetrical with respect to the center line 17 . Each socket lock portion 56 is formed to be wider in the axis-orthogonal direction as it goes upward. Each socket locking portion 56 has a general shape like a wine glass. In addition, for convenience of explanation, in FIG. 7 , the sealing member 53 and the socket housing 55 are omitted from drawing.

Continuing to refer to FIG. 7 , each socket locking portion 56 has a socket first interference surface 60 (socket interference surface) and two socket locking side surfaces 61 .

The first interference surface 60 of the socket is flat and faces upward. In this embodiment, the first interference surface 60 of the socket is orthogonal to the insertion and extraction direction. The first interference surface 60 of the socket spans the center line 17 and extends in the axis-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 side facing forward and the other side facing rear. That is, both socket locking sides 61 face the axis-orthogonal direction. Each socket locking side surface 61 has a socket second interference surface 62 and a lock receiving curved surface 63 .

The socket second interference surface 62 is planar and extends downward from the end of the socket first interference surface 60 in the axis-orthogonal direction. The second interference surface 62 of the socket is inclined toward the center line 17 as it goes downward.

The lock receiving curved surface 63 is formed below the second interference surface 62 of the socket, and is curved in an arc shape such that the center line 17 is convex. Therefore, it can be said that the lock receiving recess 64 defined by the lock receiving curved surface 63 is formed in each socket locking side surface 61 . The lock receiving recess 64 is formed to be concave toward the center line 17 .

(operate)

Next, the operation of the lever connector 1 will be described with reference to FIGS. 8 to 10 . In addition, in each figure, the servo motor 70 to which the socket connector 3 is attached is represented by a two-dot chain line. In addition, for convenience of explanation, similarly to FIG. 5 , in FIGS. 8 to 10 , a cross section is shown in which one arm 33 of the lever 6 is divided into two parts in the thickness direction.

In FIG. 8 , in order to fit the plug connector 2 into the receptacle connector 3 , the relative state in which the plug connector 2 and the receptacle connector 3 face each other in the insertion and extraction direction is shown. As shown in FIG. 8 , in this relative state, the lever 6 is maintained in the unlocking position, where the operating portion 34 is located higher than the plug connector body 5 .

From this relative state, when the plug connector 2 is moved toward the receptacle connector 3 , first, the plug housing 12 of the plug connector body 5 of the plug connector 2 is seated on the sealing member 53 of the receptacle connector 3 . In this state, by pressing the operation part 34 downward with your finger, the lever 6 is rotated in the locking direction. In this way, as shown in FIG. 9 , the locking surface 45 of the plug locking portion 41 of the lever 6 of the plug connector 2 contacts the socket second interference surface 62 of the socket locking portion 56 of the socket connector 3 , thereby preventing the lever 6 from moving in the locking direction. More spin.

Continue to press the operating part 34 downward with your fingers. In this way, since the lever 6 is prevented from rotating in the locking direction, the force that presses the operating portion 34 downward becomes a driving force that directly moves the plug connector 2 downward. This driving force causes the plug connector 2 to move further downward along with the elastic deformation of the sealing member 53 . Thereby, the socket housing 55 shown in FIG. 6 is accommodated in the socket receiving space 14 shown in FIG. 4 . Returning to FIG. 9 , when the plug connector 2 moves downward, the locking surface 45 of the plug locking portion 41 moves downward while contacting the socket locking side surface 61 of the socket locking portion 56 . Here, since the socket locking side surface 61 is inclined so as to be closer to the center line 17 as it goes downward, when the plug connector 2 moves downward, the lever 6 slightly rotates in the locking direction.

Finally, when the plug housing 12 of the plug connector 2 and the socket housing 55 of the socket connector 3 touch in the plugging and unplugging direction, the plug connector 2 can be prevented from moving further downward. At the same time, as shown in FIG. 10 , the plug lock portion 41 is accommodated in the lock receiving recess 64 . Thereby, the socket locking part 56 and the plug locking part 41 are adjacent downward in this order, thereby preventing the plug connector 2 from being pulled out of the socket connector 3 .

In addition, 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 further rotating in the unlocking direction. Thereby, the lever 6 is maintained in the locked position shown in FIG. 10 . By maintaining the lever 6 in the locked position, the lever connector 1 is brought into a fitted state.

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

In the mating state shown in FIG. 10 , when the mating form of the plug connector 2 with respect to the receptacle connector 3 is skewed, the plug first interference surface 42 and the receptacle first interference surface 60 are brought into contact with each other to prevent mating. The form is more skewed. Similarly, when the mating form of the plug connector 2 with respect to the receptacle connector 3 is skewed, the plug second interference surface 44 and the receptacle second interference surface 62 are brought into contact with each other to prevent the mating form from being further skewed. Therefore, even if the contact portion of the plug connector 2 and the receptacle connector 3 is worn due to vibration, or the damage between the plug connector 2 and the receptacle connector 3 becomes large, the above-mentioned structure can still maintain the plug. The connector 2 is in a stable mating form with the receptacle connector 3.

In addition, 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 can be operated to release the engagement state between the lock spring 31 and the lever lock portion 20, and at the same time, the lever 6 can be moved in the unlocking direction. Rotate. Thereby, since the plug lock part 41 shown in FIG. 10 is pulled out from the lock receiving recessed part 64, the plug connector 2 can be pulled upward from the receptacle connector 3.

The preferred embodiments of the present invention have been described above. The above-mentioned embodiments have the following characteristics.

As shown in FIGS. 1 to 7 , the rod-type connector 1 includes a plug connector 2 , a plug connector body 5 and a rod 6 . The rod 6 is rotatably supported on the plug connector body 5 and has a plug locking portion. 41 and the operating part 34; and the socket connector 3 has a socket locking part 56. As shown in FIG. 10 , the receptacle locking portion 56 and the plug locking portion 41 are adjacent to each other in the downward direction through the operating portion 34 of the operating lever 6 in this order, thereby preventing the plug connector 2 from being removed from the receptacle connector 3 Pull it out. The rod 6 has a planar plug first interference surface 42 (plug interference surface). The socket connector 3 has a planar socket first interference surface 60 (socket interference surface). In the mated state in which the plug connector 2 and the socket connector 3 are fitted, the plug first interference surface 42 and the socket first interference surface 60 are arranged to face each other and are viewed along the axial direction of the rotation axis 23 of the rod 6 , is arranged between the plug locking portion 41 and the rotation axis 23 of the lever 6 . In the mated state of the lever connector 1 , when viewed along the rotation axis direction, the rotation axis 23 of the lever 6 is disposed on the opposite side to the operating portion 34 so as to sandwich the center line 17 . The socket receiving space 14 of the plug connector body 5 is divided into two parts in the orthogonal direction. When the mating form of the plug connector 2 with respect to the receptacle connector 3 is skewed, the first interference surface 42 of the plug and the first interference surface 60 of the receptacle are in contact with each other, thereby preventing the mating form from being further skewed. According to the above structure, compared with the case where the rotation axis 23 is arranged on the center line 17 , since the plug first interference surface 42 and the socket first interference surface 60 can be ensured to a large extent, it is possible to achieve a high degree of avoidance of the plug first interference surface 42 And the effect of distortion of the fitting shape caused by the first interference surface 60 of the socket.

In addition, in the mated state of the lever connector 1 , when viewed in the rotation axis direction, the plug lock portion 41 and the rotation axis 23 of the lever 6 are positionally misaligned in the axis-orthogonal direction. Specifically, in the mated state of the lever connector 1 , the plug locking portion 41 is disposed between the center line 17 and the operating portion 34 when viewed in the rotation axis direction. According to the above structure, since the plug first interference surface 42 of the rod 6 can cover the socket first interference surface 60 of the socket connector 3 with a wide area, it is possible to further avoid the interference caused by the plug first interference surface 42 and the socket first interference surface. The effect of the distortion of the fitting shape caused by the surface 60.

In addition, in the mated state of the lever connector 1 , the plug first interference surface 42 and the socket first interference surface 60 are arranged so as to be orthogonal to the mating direction.

In addition, as shown in FIG. 10 , in the mated state of the lever connector 1 , when viewed along the rotation axis direction, the plug first interference surface 42 and the socket first interference surface 60 are arranged to connect the plug locking portion 41 and the lever 6 The straight line P of the rotation axis 23 intersects.

In addition, in the mating state of the lever connector 1 , the socket locking portion 56 is linearly symmetrical with respect to the center line 17 when viewed along the rotation axis direction. According to the above configuration, the plug connector 2 can be fitted into the receptacle connector 3 by reversing the direction in the axis-orthogonal direction.

In addition, as shown in FIGS. 6 and 7 , the socket connector 3 further includes a socket base 54 (base) having a plate thickness direction parallel to the downward direction, and a socket housing 55 . The socket housing 55 cylindrically extends upward from the socket base 54 . The socket lock portion 56 is formed to protrude upward from the socket base 54 .

Furthermore, as shown in FIG. 7 , the socket locking portion 56 has two socket locking side surfaces 61 facing in the direction orthogonal to the axis when viewed in the rotation axis direction. In each socket locking side surface 61, a lock receiving recess 64 for receiving the plug lock portion 41 is formed.

The socket lock portion 56 is formed to become wider in the axis-orthogonal direction as it goes upward when viewed along the rotation axis direction.

In addition, Japanese Patent Publication No. 2018-206517 discloses a diamond-shaped locking member. However, since it is common technical knowledge that the cam follower in Patent Document 1 is a cylindrical column, the cam follower and the above-mentioned locking member cannot be replaced.

This application claims priority based on Japanese Patent Application No. 2019-160346 filed on September 3, 2019, and the entire content of the patent application is incorporated herein by reference.
