The pivot holes 71 can be engaged with the pivot shaft portion 28 by being mutually guided by the inclined surfaces, and the receptacle connector 50 is centered on the pivot shaft portion 28 with respect to the plug connector 10 in the engaged state. It can swing. It should be noted that the center of the axis of the pivot shaft 28 (the center of the axis of the swinging shaft) is marked with a symbol X as appropriate.

An operation portion 74 that is pressed to release the engagement state of the lock arm 70 is formed at the end (upper end) of the anti-engagement portion of the lock arm 70. The lower end of the lock arm 70 having the pivot support hole 71 is bent to the left and right around the joint with the connecting portion 51 to deform the pivot support hole 71 with respect to the pivot support shaft portion 28. And can be displaced to a position where the engagement can be released.

Although the receptacle connector 50 can swing relative to the plug connector 10 about the pivot shaft 28 as described above, the receptacle connector 50 can move in one direction (FIG. 14).
(Clockwise direction in FIG. 14) is restricted when the connecting portion 51 comes into contact with the inner wall portion 29a of the V-shaped groove 29, and swinging in the other direction (counterclockwise direction in FIG. 14) is performed in the receptacle housing. When the lower end of the housing body 61 of the 60 abuts the upper end of the front wall 26 of the base portion 21, the restriction is limited. Here, at the position where the fitting convex portions 62 and 63 and the fitting concave portion 27 are fitted and removed from each other (referred to as “fitting / disengaging position”), the lower end of the housing body 61 and the front wall 2 of the base portion 21.
Since there is only a slight gap between the upper end of 6, this fitting / removing position can be regarded as a position where swinging in one direction (clockwise direction) is restricted. Therefore, the receptacle connector 50 substantially includes a fitting / removing position (also referred to as “swing initial position”) at which the fitting convex portions 62 and 63 and the fitting concave portion 27 are fitted and removed, and a connecting portion 51. Can swing between a position (referred to as “swing limit position”) that contacts the inner wall surface 29a of the V-shaped groove 29 (in this embodiment, within an angle range of about 60 degrees).

Next, in the connector 1 configured as described above, when the fitting projections 62 and 63 of the receptacle housing 60 and the fitting recess 27 of the plug housing 20 are fitted and connected, the fitting projection of the receptacle connector 50 is connected. The parts 62 and 63 are aligned with the fitting recess 27 of the plug connector 10, and the receptacle connector 50 is lowered from directly above the plug connector 10. When the receptacle connector 50 is brought close to the plug connector 10 from above, the pivot shaft portion 28 of the plug connector 10 enters the guide groove 72 of the plug connector 10 and this guide groove 7.
2 is in sliding contact with the inner surface. When the inclined surface 28a of the pivot shaft portion 28 abuts on the inclined surface 73 of the guide groove 72, the pivot shaft portion 28 presses the lock arm 70 left and right outwards under the action of the inclined surfaces. Then, the lock arm 70 is bent and deformed in a direction away from the pivot shaft portion 28. When the inclined surface 28a of the pivot shaft 28 climbs over the inclined surface 73 of the guide groove 72, the lock arm 70 that has been bent and deformed to the left and right outwards returns to a vertical posture by its own restoring elasticity, and the pivot shaft portion 28 engages with the pivot hole 71. Thus, when the pivot shaft 28 is engaged with the pivot hole 71, a click feeling is obtained. At the same time, the fitting convex portions 62 and 63 are fitted into the fitting concave portion 27, and the receptacle housing 60 and When the plug housing 20 is fitted, the receptacle connector 50 and the plug connector 10 are coupled.

At the same time, the contact portion 31 of the first plug contact 30 enters between the pair of elastic deformations 82 from the contact receiving port 86 of the first receptacle contact 80 through the contact insertion port 62 c, and the left and right sides of the first receptacle contact 80. The contact portion 85 is elastically contacted while being sandwiched between the contact portions 85. Similarly, the contact portion 41 of the second plug contact 40 is
Contact receptacle 9 of second receptacle contact 90 through contact receptacle 63c
6 and elastically contact in a state of being sandwiched between the left and right contact portions 95 of the second receptacle contact 90. As a result, the cable C joined to the receptacle contacts 80 and 90 and the board B joined to the plug contacts 30 and 40 are electrically connected via both contacts, and both the connectors 10 and 50 are connected. Signal transmission between them becomes possible.

Here, as described above, each receptacle contact 80, 90 has a pair of left and right elastic deformation portions 82, 92 (that is, a total of four contact portions 85, 95, respectively). The receptacle contacts 80 and 90 and the plug contacts 30 and 40 can be contacted at four points at the maximum. At the fitting / removing positions of the connectors 10 and 50, the contact portion 31 of the first plug contact 30 is in contact with only one set of contact portions 85 of the first receptacle contact 80. The plug contact 30 contacts at two points. On the other hand, since the contact portion 41 of the second plug contact 40 is in contact with the two sets of contact portions 85 of the second receptacle contact 90, the second receptacle contact 90 and the second plug contact 40 are in contact at four points.

The plug housing 20 has a front wall 26 protruding upward from the base portion 21 in order to prevent erroneous fitting between the fitting convex portions 62 and 63 of the receptacle housing 60 and the fitting concave portion 27 of the plug housing 20. When the receptacle housing 20 and the plug housing 70 are in a normal orientation, the receptacle housing 20 and the plug housing 70 are allowed to be fitted together.
When the plug housing 70 and the plug housing 70 are not in the proper orientation, the fitting of the two is restricted (the front wall 26 and the housing body 61 abut and the fitting convex portions 62 and 63 are not fitted into the fitting concave portion 27). Thus, a stable connection can be obtained without damaging the contacts 30, 40, 80, 90 due to erroneous fitting of the connectors 10, 50.
Further, as described above, the front wall 26 also functions as a swing range limiting means for limiting swinging of the receptacle connector 50 in the other direction (clockwise direction in FIG. 14 and the like).

Subsequently, in a state where the fitting convex portions 62 and 63 of the receptacle housing 60 and the fitting concave portion 27 of the plug housing 20 are fitted and connected as described above, the receptacle connector 50 is pivotally supported with respect to the plug connector 10. When the rocker 28 is relatively swung around the center 28, the receptacle contacts 80 and 90 are swung while maintaining the state in which the plug contacts 30 and 40 are sandwiched and elastically contacted. Here, as described above, the receptacle connector 50 can swing with respect to the plug connector 10 between the fitting / removing position and the swing limit position.
The flow of this operation is shown in FIGS. 14 to 16 (illustration of the board B and the cable C is omitted), and will be briefly described below. In the figure, the rocking trajectories of the contact portions 85, 95 of the receptacle contacts 80, 90 in the receptacle connector 50 (in other words, the trajectory of the contacts between the receptacle contacts 80, 90 and the plug contacts 30, 40) are indicated by bold lines. It is added.

First, as shown in FIG. 14, in the fitting / removing position (swinging initial position) where the fitting convex portions 62 and 63 of the receptacle housing 60 and the fitting concave portion 27 of the plug housing 20 are fitted and removed, as described above. Thus, the first receptacle contact 80 and the first plug contact 30 are in contact at two points, and the second receptacle contact 90 and the second plug contact 40 are in contact at four points.

From this state, as shown in FIG. 15, when the receptacle connector 50 is swung around the pivot shaft portion 28 by a predetermined angle from the swing initial position, the contact portion 31 of the first plug contact 30 is obtained.
Enters both of the two elastic deformation portions 62 of the first receptacle contact 80 and elastically contacts these four contact portions 85, and the first receptacle contact 80 and the first plug contact 30 are at four points. Contact. On the other hand, the contact portion 41 of the second plug contact 40 is in elastic contact with the two sets of contact portions 95 of the first receptacle contact 90 and maintains a state where they are in contact with each other at four points.

Then, as shown in FIG. 16, when the receptacle connector 50 reaches the swing limit position,
The connecting portion 51 of the receptacle connector 50 comes into contact with the inner wall surface 29a of the V-shaped groove 29, thereby restricting the swing of the receptacle connector 50. In this swing limit position,
The first receptacle contact 80 and the first plug contact 30 remain in contact with each other at four points, and the second receptacle contact 90 and the second plug contact 40 are four.
Maintains contact with dots. When the receptacle connector 50 is swung in this way, the swing locus of the contact portions 85 and 95 of the receptacle contacts 80 and 90 is viewed from the axial direction of the pivot shaft portion 28 (the direction perpendicular to the paper surface of FIG. 14 and the like). Is the contact part 3 of the plug contacts 30, 40
In other words, the positions of the contact points between the receptacle contacts 80 and 90 and the plug contacts 30 and 40 are displaced so as to draw an arc around the pivot shaft 28. I understand.

Since the contact relief holes 87 and 97 are formed in the upper plate portions 81b and 91b of the receptacle contacts 80 and 90, the plug contact 30 can be obtained even if the depth (the vertical dimension) of the receptacle contacts 80 and 90 is reduced. , 40 protrude from the contact relief holes 87, 97 without interfering with the upper plate portions 81b, 91b and can be smoothly oscillated and displaced.

As can be seen from the above, the receptacle housing 60 and the plug housing 20
And the contact portions 31 and 41 of the plug contacts 30 and 40 are in elastic contact with the contact portions 85 and 95 of the receptacle contacts 80 and 90 in contact with each other. When the contact portions 85 and 95 of the receptacle contacts 80 and 90 are swung relative to the plug connector 10.
Each slides while maintaining a state of elastic contact with 40. Therefore, even if the receptacle connector 50 is swung relative to the plug connector 10, the receptacle contacts 80 and 90 and the plug contacts 30 and 40 are always connected regardless of the relative positions of the receptacle connector 50 and the plug connector 10. Thus, the plug connector 10 and the receptacle connector 50 can always be in an electrically connected state.

It should be noted that the connectors 10 and 50 from the state in which the connectors 10 and 50 are fitted and connected in this way.
To separate the plug connector 10 from the plug connector 10, the right and left operation portions 74 of the lock arm 70 are pressed inward (towards each other). The pivot support hole 71 of the receptacle connector 50 and the plug connector 10
The receptacle connector 50 may be pulled away from the plug connector 10 in a state in which the engagement with the pivot shaft 28 is released.

Therefore, according to the movable connector 1 according to the present embodiment, the first and second plug contacts 80 and 90 are arranged in two rows along the width direction of the plug housing 60, and the first and second receptacle contacts 30 are arranged. , 40 are juxtaposed in two rows along the width direction of the receptacle housing 20, and the plug connector 50 is swung relative to the receptacle connector 10 when viewed from the axial direction of the pivot shaft 28. Thus, the swing locus of the contact portion 85 of the first receptacle contact 80 in the predetermined swing range overlaps the contact portion 31 of the first plug contact 30 and the swing locus of the contact portion 95 of the second receptacle contact 90 is the first. 2 plug contact 4
The receptacle connector 50 and the plug connector 1 are arranged so as to overlap the 0 contact portion 41.
Regardless of the relative position to 0, the first receptacle contact 80 and the first plug contact 3
The second receptacle contact 90 and the second plug contact 40 are configured to be relatively displaced from each other while maintaining a state in which the second receptacle contact 90 and the second plug contact 40 are always in contact with each other. Therefore, even when both the plug connectors 30 and 40 and the receptacle contacts 80 and 90 are arranged in two rows, the receptacle connector 50 is connected to the plug connector 10 while maintaining the energized state between the plug connector 10 and the receptacle connector 50. Therefore, it can be suitably used as an electrical connection means between the fixed body and the movable body, and the number of signal lines (the number of poles) increases. However, as compared with the case where the contacts are arranged in a line, the dimension in the width direction of the housing can be shortened to approximately half, and the entire connector can be reduced in size.

In the movable connector 1, the axis of the pivot shaft 28 (the axis of the swing shaft) is disposed between the plurality of first plug contacts 30 and the plurality of second plug contacts 40.
Contact of each receptacle contact 80 and 90 when the first receptacle contact 80 and the second receptacle contact 90 swing relative to the first plug contact 30 and the second plug contact 40 about the pivot shaft 28. Since the rocking radii of the portions 85 and 95 can be kept small, the entire connector can be further downsized.

Further, according to the movable connector 1 configured as described above, when the receptacle connector 50 swings relative to the plug connector 10, the receptacle contacts 80, 9
Since the contact state between the pair of 0 contact portions 85 and 95 and the contact portions 31 and 41 of the plug contacts 30 and 40 can be maintained stably, the relative positions of the receptacle contacts 80 and 90 and the plug contacts 30 and 40 can be maintained. Nevertheless, poor contact between the two is unlikely to occur, thereby improving the reliability of the electrical connection.

In this movable connector 1, the receptacle contacts 80, 90 have two pairs of elastic deformation portions 82, 92, and the receptacle connector 50 and the plug connector 10.
Receptacle contacts 80, 90 and plug contacts 30,
40 can be elastically contacted at four points, respectively, so that the number of electrical contact points can be further increased, and a contact failure is less likely to occur even with respect to a positional deviation between the two contacts. It is possible to increase the sex.

In the movable connector 1, when the plug housing 20 and the receptacle housing 60 are fitted, the contact portions 31 and 41 of the plug contacts 30 and 40 are connected to the pair of elastic deformation portions 82 and 82 in the receptacle contacts 80 and 90. Between the guide portions 83, 9
3, the contact portion 31 of the plug contacts 30, 40 is fitted when the plug housing 20 and the receptacle housing 60 are fitted together. , 41 can be introduced more smoothly between the pair of contact portions 85, 95 of the receptacle contacts 80, 90.

In the movable connector 1, the upper plate portion 8 of the receptacle contacts 80, 90 is used.
1b and 91b include contact portions 31 and 41 of the plug contacts 30 and 40 when the receptacle connector 50 and the plug connector 10 are relatively swung around the pivot shaft 28.
Are formed so that the receptacle connector 50 swings relative to the plug connector 10, and the receptacle contacts 80, 9 are formed.
When the relative position between 0 and the plug contacts 30, 40 is displaced, the plug contact 30
, 40 can pass through the contact relief holes 87, 97 without interfering with the upper plate portions 81b, 91b on the depth side of the receptacle contacts 80, 90, so that the inside of the receptacle contacts 80, 90 It is not necessary to ensure a large swinging space for the contact portions 31 and 41 in the plug contacts 30 and 40, and the receptacle contact 80
, 90 in the depth direction can be shortened.

Next, a configuration in which the movable connector 1 according to the present embodiment is applied as an electrical connection means between the fixed body 110 and the movable body 120 will be described with additional reference to FIGS. The movable body 120 is attached to the front surface of the fixed body 110 so as to be able to be opened and closed laterally by using a hinge mechanism (not shown) disposed on the left and upper sides of the front surface of the fixed body 110. The attached control device 111 and the electrical component (electrical component) 121 attached to the front side of the movable body 120 are electrically connected, and the control device 111 is configured to control the operation of the electrical component 121. ing. Here, the combination of the fixed body 110 and the movable body 120 is
For example, when applied to a pachinko machine, the main body frame member that accommodates and holds the game board in a standing posture corresponds to the fixed body, and is attached to the front side of the main body frame so that it can be opened and closed laterally and attached and detached via a hinge mechanism. A glass frame member provided with an electric decoration device (LED or the like), an acoustic device (speaker) or the like corresponds to the movable body. The movable connector 1 of the present embodiment is not limited to a gaming machine represented by a pachinko machine, but is a control device or device having an openable operation panel, or a foldable portable terminal or notebook personal computer. The present invention can also be applied to other devices.

The movable connector 1 is an electrical connection means between the fixed body 110 and the movable body 120, and a control device 111 attached to the fixed body 110 and an electrical component 12 attached to the movable body 120.
It plays the role which electrically connects between.

The plug connector 10 is mounted on a substrate B connected to an electrical component 121 disposed on the front side of the movable body 120 via an electric wire (not shown), and the lead portion 33 of the plug contacts 30 and 40. , 44 are connected to the electrical component 121 via the substrate B connected thereto.

The receptacle connector 50 is connected to the control device 111 via the cable C to which the receptacle contacts 80 and 90 are connected. The receptacle connector 50 is fixed to the fixed body through the cable lead-out hole 112 formed on the left side edge of the fixed body 110. 110 is pulled out to the front side. The cable lead-out hole 112 is formed in the state where the movable body 120 is closed with respect to the fixed body 110.
The board B and the plug connector 10 attached to the rear surface side of the board 20 are arranged so as to face the front and rear.

The movable connector 1 has a state in which the movable body 120 is opened with respect to the fixed body 110 (the movable body 110).
The plug connector 1 fixed to the rear surface side of the movable body 120 via the substrate B
The receptacle connector 50 drawn out to the front side of the fixed body 110 is fitted and connected to 0, and is integrally attached to the rear side of the movable body 120. When the plug connector 10 and the receptacle connector 50 are thus fitted and connected, the cable C is connected via the connectors 10 and 50.
The control device 111 connected to the electric device 121 and the electric component 121 connected to the substrate B are electrically connected, and the electric component 121 can be operated by signal transmission between them.

When the movable body 120 is opened to the fixed body 110 as described above, as shown in FIG. 18, the receptacle connector 50 is positioned at the initial swing position where the plug connector 10 can be attached and detached, and the cable C end. The portion from the receptacle connector 50 to the cable lead-out hole 112 in the section (the cable portion drawn forward from the cable lead-out hole 112) extends in the front-rear direction.

Then, as shown in FIG. 19, when the movable body 120 is swung backward by the hinge mechanism,
The receptacle connector 50 swings relative to the plug connector 10 by tension generated in the cable C (so as to maintain its own position). As described above, the receptacle connector 50 is swingable relative to the plug connector 10, and the cable C is forcibly bent due to the operation of the movable body 120, so that excessive stress (mainly bending stress) is generated. However, the pivot shaft 28 with respect to the receptacle connector 50 due to the tension generated in the cable C.
When a rotating moment (force moment) is applied, the receptacle connector 50 swings relative to the plug connector 10 so as to follow the operation of the movable body 120.
Since the posture can be flexibly changed so as to release the bending stress, it is possible to prevent local stress concentration in the cable C and prevent damage to the connector. Therefore, even when the receptacle connector 50 reaches the swing limit position with respect to the plug connector 10, the cable C can be maintained in a state where the cable lead-out hole 112 extends substantially back and forth without being bent.

When the movable body 120 swings and opens with respect to the fixed body 110 in this way (ie,
Even when the receptacle connector 50 swings relative to the plug connector 10)
The receptacle contacts 80 and 90 and the plug contacts 30 and 40 are relatively displaced while maintaining a constant contact state, and the energized state between the receptacle connector 50 and the plug connector 10 is maintained.

As described above, according to the movable connector 1 according to the present embodiment, even if the movable body 120 opens and closes relative to the fixed body 110 and the cable C connected to the receptacle connector 50 is forcibly bent, the tension generated in the cable C is increased. As a result, a moment around the swing axis (moment of force) acts on the receptacle connector 50, so that the receptacle connector 50 follows the operation of the movable body with respect to the plug connector 10 between the connectors 10 and 50. Since the posture can be flexibly changed so as to release the bending stress by relatively swinging while maintaining the energized state, local stress concentration on the cable C is avoided and the connector is It is possible to prevent damage in advance.

In addition, since the cable C is not greatly bent by the opening / closing swing of the movable body 120 in this way, a slight allowance may be given to the cable C. A situation in which the cable C is sandwiched between the movable body 120 and the movable body 120 can be prevented.
