Description

  The present invention relates to an electrical wiring connection structure for electrical connection. The present invention also relates to an electrical equipment for gaming machines having the connection structure, and a gaming machine to which the electrical equipment is attached.

  For example, a machine frame of a pachinko machine (game machine) is equipped with a large number of equipment (electrical equipment) including electrical wiring, as exemplified by a game board, a launch handle, a payout device, and the like. These electrical devices are connected to the main control board, launch control board, payout control board, etc. via connection terminals (male connector and female connector) in order to input / output power and control signals and to ground (earth). Each wiring board is electrically connected. Many are connected using a harness, but if a harness is used, electrical connection failures are likely to occur due to door opening and closing operations, etc., and cables are entangled and noise is likely to occur. There are various problems such as difficulty in maintaining a good control state. Therefore, a gaming machine has been proposed that has a configuration in which connectors of various control boards can be directly connected without using a harness (see Patent Document 1).

JP 2008-154688 A

  However, if the connectors of various control boards are directly connected, it is difficult to determine the connection state of the connectors, damage to the connection terminals due to excessive pressing, or connection failure due to the connection terminals not being reached, resulting in poor electrical connection. There is a problem that it is easy to cause. For this reason, the occurrence rate of defective products is influenced by the skill level of the assembly operator, which deteriorates the yield of the product and eventually increases the manufacturing cost of the pachinko machine. In addition, if an external force that is accidentally applied in the direction of connector removal is applied due to vibrations such as opening and closing the door, the connection terminals may be accidentally pulled out, resulting in poor electrical connection due to incomplete connections. There are problems such as disrupting games. Furthermore, since the positional relationship of the connectors must be made strict in design, there is a problem that the clearance must be reduced, the assembly is troublesome, and problems such as breakage of the connection terminals are likely to occur.

  Therefore, the present invention is to provide an electrical wiring connection structure, an electrical equipment for a gaming machine, and a gaming machine that can securely connect an electrical equipment, a control board, and the like directly via a connector.

  In order to solve the above-described problems, the present invention provides a connection structure for a pair of connectors, which is provided in an attachment portion and has a connection terminal, and either of the connectors is attached to a support portion formed by an elastic body. The support portion is elastically deformable in the insertion / removal direction of the connector, and when the connector is coupled, the support portion is elastically deformed when the connection terminal moves beyond a predetermined amount in the insertion direction. Absorbing an excessive amount of movement of the connection terminal, and when the external force applied in the direction of removing the connector is inadvertently applied, the support portion is elastically deformed to absorb the load. And “Elastic body” as used herein refers to a material that has the property of deforming when a force is applied but returning to its original dimensions when the force is unloaded. Synthetic rubber such as butadiene rubber and butyl rubber, polynorbornene, polychlorinated In addition to a synthetic resin such as a vinyl-based resin, a thin plate-like elastic metal is included.

  In this electrical wiring connection structure, any one of the connectors is attached to a support portion formed of an elastic body in the main body portion, and the support portion can be elastically deformed in the connector insertion / removal direction. Excessive force, vibrations such as door opening / closing operations, etc. are absorbed by the elastic deformation of the support portion, and damage to the connection terminals and poor electrical connection can be eliminated. That is, in the connection state of the connector in this electrical wiring connection structure, even if an external force applied in the connector removal direction is inadvertently applied, the support portion is elastically deformed so as to move within a predetermined range, and the connector is removed in the connector removal direction. In order to absorb the load, the connector is not accidentally removed. Further, when the connector is released, when an external force exceeding a predetermined amount (elastic limit of the support member) is applied to the connector in the removal direction, the connector moves in the removal direction and the connection of the connection terminal is released. In addition, by forming the support portion with an elastic body, it is not necessary to provide a separate spring or elastic piece for the same purpose, which contributes to cost reduction and does not require extra space. Contributes to downsizing (miniaturization).

  Moreover, in these electrical wiring connection structures, the support portion may have a plate-like portion having a predetermined thickness, and the connector may be attached to the plate-like portion. With this configuration, the support portion is easily elastically deformed in response to the movement of the connector, and it is possible to reliably eliminate breakage of the connection terminals and poor electrical connection.

  Moreover, the said connector can be set as the structure provided so that a movement in the direction which cross | intersects the insertion / extraction direction of a connector with respect to the said support part is possible. In this way, by allowing floating movement at the time of assembly (at the start of contact and at the time of insertion), it is possible to absorb a wide range of assembly errors and dimensional tolerances existing in each part when incorporating both connection terminals into electrical equipment. It is possible to cope with (absorb) vibrations and shocks at the time of assembling, so that the incidence of defective products due to poor connection can be reduced regardless of the level of skill of the assembling operator. Further, by adopting this configuration, the connector is supported so as to be movable in a direction intersecting the connector insertion / removal direction and the connector insertion / removal direction by elastic deformation of the support portion and floating movement of the connector. A three-dimensional movement is possible via the (elastic body), and a wide range of displacement existing between the connector and the connector can be absorbed to achieve normal coupling.

  Specifically, the floating mechanism of the connector forms a gap in the insertion direction so that the floating state of the insertion-side connector can be maintained and a space in the movement direction to form a floating movement of the insertion-side connector. And a moving space to enable. For example, in a floating mechanism, a floating gap is formed by a washer with a sleeve and a washer respectively interposed between an insertion side connector and a support part, and the inner diameter of the washer with a sleeve is larger than the screw outer diameter of the screw. Thus, a moving space in the moving direction is formed.

  Moreover, in these electrical wiring connection structures, the support portion may be formed separately from the attachment portion, and a peripheral portion of the support portion may be supported by a support portion provided in the attachment portion. . In this way, by forming the support part separately and attaching the connector via the support part, the connector can be attached to the support part in advance, so attachment to the attachment part is easy. Become. Moreover, by providing so that the peripheral part of a support part may be supported, a support part becomes easy to elastically deform and the load to a connector is reduced.

  Further, in this electrical wiring connection structure, the support portion may be configured to be movable in a direction crossing a connector insertion / extraction direction with respect to the attachment portion. By adopting this configuration, the connector can be moved with respect to the mounting portion via the support portion, so that the occurrence rate of defective products due to poor connection during assembly is reduced in the same manner as the floating structure of the connector. be able to.

  Further, specifically, an insertion-side connector formed so as to be insertable with respect to the insertion-side connector mounted and fixedly held on the wiring board, and on the side opposite to the insertion direction with respect to the insertion-side connector A first receiving portion that is positioned, receives and holds the insertion-side connector by the first receiving portion, and is capable of floating movement in a plane parallel to the plane including the moving direction of the insertion-side connector And a second receiving part positioned on the opposite side of the insertion direction with respect to the support part, and an attachment part that receives and holds the support part by the second receiving part. In the direction, the distal end of the insertion side connector is positioned so as to protrude from the distal end of the support portion, so that when the distal end portion of the insertion side connector is inserted into the inserted side connector, the support portion is attached to the mounting portion. Part It may be such that it can be floating move.

  Furthermore, by using the first floating movement in which the connector itself floats and the second floating movement in which the support portion floats in combination, the floating movement range (that is, the insertion side connector) The adjustable range) can be expanded. And, by the two-stage floating movement, it is possible to reliably absorb the load applied in the direction intersecting the connector insertion / extraction direction due to vibration / impact etc. during the game, so that the connector is not damaged and contact failure is caused. The player can concentrate and enjoy the game without interrupting the game. In addition, since the first floating movement and the second floating movement are independent from each other, the insertion side connector and the support portion can simultaneously move in a direction intersecting when viewed from the insertion direction. In general, it occurs in the order of the first floating movement → the second floating movement, but when it occurs in the order of the second → first, if it occurs almost simultaneously, only the first or second It can happen.

  Also, the electrical equipment for gaming machines of the present invention comprises the above-described electrical wiring connection structure, is attached to a gaming machine such as a pachinko machine, and is involved in the execution of the game in the gaming machine, and the mounting portion is the above-mentioned A main body for mounting on a gaming machine can be configured.

  As described above, when the electrical equipment for gaming machine is attached to the gaming machine (machine frame) through the above-described electrical wiring connection structure, the supporting portion can be elastically deformed in the insertion / extraction direction of the connector. Excessive force can be absorbed when the connection terminal is installed in the electrical equipment, and it can also handle (absorb) vibration and shock during assembly, so there is no problem due to poor connection regardless of the skill level of the assembly operator. The occurrence rate of non-defective products can be reduced. In addition, because it can handle (absorb) vibrations and shocks received after assembly, reduce the incidence of defective products at the distribution stage for transportation and storage as electrical equipment and at the stage of installation in various application devices and products. Can do.

  In addition, the gaming machine of the present invention can be configured such that the electrical equipment for gaming machines is attached to the machine frame via the main body.

  Thus, the support part can be deformed even after assembly. As a result, vibrations and shocks received after assembly can be accommodated (absorbed), reducing the incidence of defective products at the distribution stage for transporting and storing gaming machines and the installation stage for installing gaming machines at amusement stores. can do.

Specifically, the following cases can be exemplified.
(1) When a launch handle as an electrical equipment for a gaming machine is attached to a front frame of a pachinko machine as a machine frame of a gaming machine by linear movement;
(2) When the payout device as the electrical equipment for the gaming machine is attached to the inner frame of the pachinko machine as the machine frame of the gaming machine by linear movement or rotation;
(3) When a game board as an electrical equipment for a gaming machine is attached to the inner frame of a pachinko machine as a machine frame of the gaming machine by turning.

  In addition, the tip of the insertion-side connector is inserted into the insertion-side connector in the attachment portion on the insertion-side connector side with floating movement on the opposite side of the insertion direction with respect to the insertion-side connector. In this way, it is desirable that a guidance guide unit for guiding guidance is arranged.

  In this way, floating movement is possible when the distal end of the insertion-side connector is guided and guided by the guidance guide portion and inserted into the insertion-side connector, so that assembly errors and dimensional tolerances (positional deviation) of both connectors are possible. Can be quickly absorbed by floating movement. Specifically, the guide guide portion may be configured by a guide wall having a flat or curved inclination (for example, a tapered plane) such that the interval becomes narrower toward the distal end side (lower side) in the insertion direction. it can. Further, the guide guide portion may be formed separately from the insertion-side connector, or may be formed integrally (for example, integrally formed) with the insertion-side connector.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko machine as a gaming machine, and FIG. 2 is a rear view of the pachinko machine.

A discharge basket 15 is provided for guiding the paid game balls to the ball tray 7.

  In the present specification, the vertical direction means the direction (for example, the vertical direction) in which the game ball flows down along the board surface of the game board 5. Further, the left and right direction means a direction (for example, a horizontal direction) intersecting with the up and down direction along the board surface of the game board 5, and means the left side and the right side when viewed from the player side. Further, the front-rear direction means a direction intersecting (for example, orthogonal) with the game board 5, the side (front side) facing the player is the front side (front side), and the opposite side (back side) is It is the rear side (rear side).

  On the board surface (front surface) of the gaming board 5 (electric equipment for gaming machines), as shown in FIG. A display device 18 equipped with a liquid crystal display unit and electrical decoration is mounted in the center of the game area 5a, and a big prize opening 19 that opens and closes a door by an electric drive source below the display device 18 (lower center of the game area 5a). (Attacker) is arranged. Further, between the display device 18 and the special winning opening 19, a starting opening 20 constituted by an electric tulip (electric chew) that displays the liquid crystal display unit in a variable manner by winning is arranged. The game area 5a is provided with a winning opening 21 equipped with an illumination device. Thus, the game board 5 is provided with many electrical components.

  3 is a perspective view of the launch handle provided with the electrical wiring connection structure according to the present invention as seen from the back, FIG. 4 is an exploded rear perspective view of the launch handle, and FIG. 5 is a rear view of FIG. . As shown in FIGS. 3 and 4, the firing handle 8 has a grip body 8 a that is located on the rear side and opens to the front side, and a cap 8 b that is located on the front side and opens to the rear side, facing each other like a palm. Thus, a rotation lever 8c (rotation operation member) is disposed between the grip body 8a and the cap 8b. The firing handle 8 has a cylindrical main body 130 (attachment portion) of the grip body 8a fixed (attached) to an attachment recess 6a formed in the front frame 6 of the pachinko machine 1 via a fastening member 131 such as a screw. The cap 8b is fixed to the main body 130 (see FIG. 9B). Further, the pin hole 110a (connection terminal) of the rectangular male connector 110 (insertion side connector) held by the firing handle 8 (main body part 130) is mounted (fixed) on the firing handle relay board 23 (wiring board). It is inserted (connected) into the connection pin 100a (connection terminal) of the held rectangular female connector 100 (inserted connector) (see FIGS. 7 to 9). Control signals and power are input and output between the launch handle 8 and the launch control board (not shown) via the launch handle relay board 23.

  The male connector 110 described above is provided at the rear end opening of the main body 130 of the firing handle 8 via a support member 120 (support), and the main body 130 is connected to the player side (from the rear end opening). A plurality of (for example, three) boss portions 130a and a plurality of (for example, four) rib walls 130b (support portions) that protrude from the inner wall at a predetermined interval and are supported by the support member 120 are located on the opposite side of the insertion direction. Is formed. That is, a storage portion (attachment portion) for the support member 120 is formed in the rear end opening of the main body portion 130.

  The male connector 110 is attached to the support member 120 so as to protrude in the insertion direction (rear side) into the female connector 100 and extends in the left-right direction as shown in FIG. Through the support member 120 and the insertion portion 112 that protrudes rearward (insertion direction) from the center of the pedestal 111, with respect to the insertion direction (protrusion direction). Floating movement is possible in the direction of crossing (for example, orthogonal).

  The support member 120 is formed in a pseudo disk shape by an elastic body that is elastically deformable in a predetermined direction, such as a synthetic rubber such as butadiene rubber or butyl rubber, polynorbornene, or polyvinyl chloride resin. The peripheral edge is received and held by the rib walls 130b (for example, four locations), and can be elastically deformed in the insertion / removal direction of the male connector 110. Further, the support member 120 has a plate-like portion having a predetermined thickness, and an insertion hole 120c through which the wiring of the male connector 110 is inserted is formed substantially at the center, and the front side of the male connector 110 (what is the insertion direction? On the opposite side, there are a plurality of (for example, two) seating portions 120a (first receiving portions) sandwiching the insertion hole 120c, and the male connector 110 is received and held by the seating portions 120a, and the second described later. Floating in a direction intersecting (for example, orthogonal to) the insertion direction (protruding direction) of the male connector 110 within a plane parallel to the plane including the moving direction of the male connector 110 (pedestal 111) via the floating mechanism 30. It is movable. Thereby, since the male connector 110 is supported so as to be movable in the insertion / removal direction and the direction intersecting the insertion / removal direction, the male connector 110 can be moved three-dimensionally via the support member 120 (elastic body). It is possible to realize a normal coupling by absorbing a wide range of displacement existing between the connector and the connector. The support member 120 may be formed of a thin plate-like elastic metal.

  5 and 6, the first floating mechanism 10 is disposed at both ends (diagonal when viewed in the circumferential direction) of the base 111 of the male connector 110 in the longitudinal direction (left and right direction), respectively. Allows movement in the circumferential and radial directions (first floating movement). On the other hand, a plurality of second floating mechanisms 30 are arranged in the circumferential direction outside the first floating mechanism 10 (for example, three locations at intervals of 120 °), and the support member 120 moves in the circumferential direction or the radial direction (second Floating movement) is possible.

  Specifically, as shown in FIG. 6A, the first floating mechanism 10 floats between the base 111 of the male connector 110 and the seat 120a of the support member 120, and the base 111 to the seat 120a. A first floating gap in the insertion direction is formed by a sleeved washer 26a and a washer 26b interposed between a screw 25 (mounting member) and a pedestal 111, respectively, so that the male connector 110 can float. The state can be maintained. Further, by setting the inner diameter d2 of the sleeve washer 26a to be larger than the screw outer diameter d1 of the screw 25, the first moving space S1 in the moving direction is formed, and the male connector 110 can be moved in a floating manner.

  On the other hand, as shown in FIG. 6B, the second floating mechanism 30 includes a plurality of (for example, three locations) in which the support member 120 received and held by the rib wall 130b of the main body 130 is bulged inside the main body 130. ) Of the boss portion 130a (the bulging portion; see FIG. 5), and the washer 27a interposed between the screw 27 and the support member 120 is integrated into the second floating gap in the insertion direction. The support member 120 can be maintained in a floating state. Further, the second moving space S2 in the moving direction is constituted by the boss portion 130a of the main body portion 130 and a plurality of (for example, three) peripheral notch portions 120b formed on the outer peripheral surface of the support member 120 so as to surround the boss portion 130a. To enable the support member 120 to move in a floating manner.

  As shown in the enlarged view of FIG. 6A, the first movement space S1 of the male connector 110 is represented by S1 = d2-d1, and is smaller than the second movement space S2 of the support member 120 (S1 <S2 ). Thereby, the shift which could not be absorbed in the first moving space S1 when the connector is connected can be reliably adjusted (absorbed) in the second moving space S2. Further, the distal end of the insertion portion 112 of the male connector 110 is positioned so as to protrude from either of the distal ends of the support member 120 and the main body 130 in the insertion direction (projection direction).

  Next, FIG. 7 is a perspective view conceptually showing a state in which the firing handle 8 is attached to the front frame, FIG. 8 is a side sectional view showing the internal structure thereof, and FIG. 9 is a side sectional view showing a connecting process of the connector subsequently. FIG.

  As shown in FIG. 8, the female connector 100 is provided via a launch handle relay board 23 held by a holding plate 16 (machine frame) fixed integrally to the front frame 6. On the back side of the holding plate 16, a storage portion 16a of the launching handle relay board 23 provided with the female connector 100 is formed. On the front side, the male connector is accompanied by the first floating movement described above. A guide wall 16c (guidance guide portion) for guiding and guiding the male connector 110 to the female connector 100 is formed integrally with an opening 16b inserted into the female connector 100 at the tip of the insertion portion 112 of 110. Has been. Specifically, as shown in FIG. 7, the guide wall 16c has a pair of tapered flat surfaces in which the interval becomes narrower toward the distal end side (lower side; rear side) in the insertion direction. A plurality of pairs (for example, three pairs) are arranged in parallel along the movement direction of 110. In addition, since a flat surface parallel to the insertion direction is formed toward the female connector 100 on the base side (the distal end side in the insertion direction) of the guide wall 16c, the difference from the male connector 110 is formed. The insertion portion 120 is held in a posture that is adjusted in the insertion direction by a pair of parallel planes (see FIG. 9). A holding wall 16d having a parallel plane is formed so as to surround the opening 16b together with the parallel plane of the guide wall 16c. A plurality of pairs (for example, two pairs) of holding walls 16 d are arranged in parallel along the moving direction of the male connector 110.

  A procedure for inserting (connecting) the male connector 110 to the female connector 100 in order to mount the firing handle 8 configured in this manner on the front frame 6 will be described with reference to FIGS. In FIG. 8, the main body 130 of the firing handle 8 is pushed backward in the mounting recess 6 a of the front frame 6. When the distal end of the insertion part 112 of the male connector 110 comes into contact with the guide wall 6c, the male connector 110 moves to the tapered plane of the guide wall 16c with a first floating movement (for example, movement to the left). And guided in the insertion direction (FIG. 9A). As a result, misalignment between the male connector 110 and the female connector 100 can be corrected.

  Further, when the distal end portion of the insertion portion 112 of the male connector 110 is inserted into the female connector 100, the support member 120 passes through the second floating mechanism 30 in addition to the first floating movement of the male connector 110. The second floating movement with respect to the main body portion 130 becomes possible. As a result, the position shift between the male connector 110 and the female connector 100 is further corrected and inserted to the limit, and the assembly (connection) operation is completed (FIG. 9B). At this time, the male connector 110 is securely held by the parallel plane of the guide wall 16c and the holding wall 16d, and does not rattle by preventing movement in the direction intersecting the insertion / removal direction of the male connector 110. The front end (open end) of 130 is located at the reference position B, and the distance L from the holding plate 16 is maintained. However, during assembly, the first and second floating movements actually occur almost simultaneously. Even if the launch handle 8 and the front frame 6 are subjected to vibration / impact during assembly, they can be absorbed by the second floating movement.

  Further, when the distal end portion of the insertion portion 112 of the male connector 110 finishes being inserted into the female connector 100, the support member 120 and the main body portion 130 are separated from the female connector 100 and maintained in a non-contact state. (FIG. 9B). Therefore, even if the launch handle 8 and the front frame 6 are subjected to vibration / impact after assembly, they can be absorbed by the second floating movement.

  In this way, the floating movement range (that is, the adjustable range) can be expanded by enabling two-stage (first and second) floating movement at the time of assembly (at the start of contact and insertion). it can. The two-stage floating movement can absorb a wide range of assembly errors and dimensional tolerances (positional deviations) existing in each part when assembling both connectors 100 and 110 into the front frame 6 and the firing handle 8. Therefore, the occurrence rate of defective products due to poor connection can be reduced regardless of the level of skill of the assembly operator.

  Further, since the first floating movement and the second floating movement are independent from each other, the movement range (adjustable range) of the male connector 110 can be expanded. Further, the male connector 110 and the support member 120 can move simultaneously in the direction intersecting when viewed from the insertion direction, and can absorb even a complicated positional shift accompanied by twisting.

  Furthermore, the first floating mechanism 10 can be smoothly operated by providing the guide wall 6c on the female connector 100 side. As a result, assembly errors and dimensional tolerances (positional deviations) of both connectors 100 and 110 can be quickly absorbed by the first floating movement.

  Further, when the male connector 110 is coupled to the female connector 100, the main body 130 is used as a reference when the pin hole 110a (connection terminal) is loaded in the insertion direction (the black arrow direction in FIG. 10A) with a predetermined value or more. When the distance L1 with the holding plate 16 is reduced (L1 <L) by moving beyond the predetermined amount from the position B, the support member 120 is elastically deformed (in the insertion direction) and the pin hole 110a (connection terminal) Absorbing an excessive amount of movement, preventing damage to the connection terminals (connection pin 100a, pin hole 110a), eliminating electrical connection failure, and maintaining the best connection state. Specifically, as shown in FIG. 10A, the peripheral portion of the support member 120 is elastically deformed to become a dish shape and absorb a load of a predetermined value or more in the insertion direction. That is, the central portion to which the male connector 110 is attached is hardly elastically deformed and maintains a stable coupled state.

  Further, in this coupled state, an external force applied in the pulling direction of the male connector 110 (FIG. 10 (b) in the black arrow direction) due to a player's handle operation or the like is inadvertently applied, and the main body 130 moves backward from the reference position B. Even if the distance L2 from the holding plate 16 is increased (L <L2), the male connector 110 maintains the coupling with the female connector 100 as it is, and the support member 120 is elastically deformed in the removal direction. In order to absorb the load (movement), the male connector 110 is not removed from the female connector 100, and the connection pin 100a and the pin hole 110a are prevented from being detached, and the best connection state is maintained. You can continue. Specifically, as shown in FIG. 10 (b), the peripheral edge of the support member 120 is elastically deformed into a hill shape and absorbs the load in the removal direction. That is, the central portion to which the male connector 110 is attached is hardly elastically deformed and maintains a stable coupled state.

  On the other hand, when it is necessary to separate the male connector 110 and the female connector 100 when exchanging the operation handle 8, the pull-out force of the male connector 110 is a predetermined amount in the removal direction (limit of elastic deformation of the support member 120). The connection between the connection pin 100a and the pin hole 110a is released when the connector moves beyond the range, and the male connector 110 and the female connector 100 can be separated.

  In the embodiment, the support member is formed separately and attached to the main body (attachment portion) in a floating state, but may be fixedly provided on the main body (attachment portion). Alternatively, a portion (support member) to which the connector is attached may be integrally formed by double molding or the like, using an elastic resin (elastic body) and an attachment portion as a rigid resin. That is, the part to which the connector is attached only needs to be formed of an elastic body.
