The electric wire 60 is inserted into each electric wire insertion hole 24, and two electric wire rows in front and rear are provided in parallel to each other. As shown in FIG. 1, the region sandwiched between the two rows of electric wires on the upper surface of the male connector 20 is covered by the intermediate cover member 40, and the region on the further front side of the electric wire on the front side is covered by the side cover member 30. Covered. Similarly, the region on the further back side of the wire array on the back side is covered with another side cover member 30. Accordingly, each gap between the electric wire 60 and the electric wire insertion hole 24 is closed by the side cover member 30 and the intermediate cover member 40.

  On the front surface 20b side of the male connector 20, a pair of engagement pieces 21 and 21 that are supported in a cantilevered manner at the lower portion of the front surface 20b and extend upward therefrom are formed. The upper end is connected to both ends of the grip 22 extending in the left-right direction. The engaging pieces 21 and 21 are elastically deformed toward the back side of the male connector 20 by pinching the grip 22.

  A relatively thin rod-shaped deformation engagement piece 28 is disposed beside each engagement piece 21. That is, a support portion 27 that protrudes forward is formed on the side of each engagement piece 21 on the front surface 20b of the male connector 20, and from a position away from the front surface 20b of the male connector 20 on the lower surface of each support portion 27, The deformation engagement piece 28 extends downward. That is, the deformation engagement piece 28 is supported in a cantilever manner by the support portion 27 disposed above, and can be elastically deformed in the left-right direction along the front surface 20b.

  As shown in FIG. 3, the female connector 10 includes a recess 10 c that accommodates the male connector 20, and a total of 24 metal rod-like board connection terminals 70 corresponding to the electric wires 60 are provided on the bottom wall 10 b. Is erected. The lower end of the board connection terminal 70 passes through the bottom wall 10b and is located on the back side of the bottom wall 10b, that is, on the back side of the female connector 3, and is inserted into a hole of a control board (not shown). Thus, the control board is electrically connected by solder.

  A peripheral wall 10a is erected around the bottom wall 10b, and recesses 15 are formed on the upper edges of the left and right side walls constituting the peripheral wall 10a. Moreover, the guide groove 14 extended in the vertical direction is formed in the inner wall right and left both ends of the front wall which comprises the surrounding wall 10a. The guide grooves 14 and 14 are fitted with guide walls 20 a and 20 a that are erected so as to extend in the vertical direction at both ends of the front surface of the male connector 20.

  On the front wall constituting the peripheral wall 10a of the female connector 10, engagement holes 12, 12 are further formed side by side in the left-right direction. When the male connector 20 is inserted into the female connector 10, the engagement claws 21 a and 21 a formed on the front surfaces of the engagement pieces 21 and 21 of the male connector 20 are located above the engagement holes 12 and 12 of the female connector 10. The male connector 20 is prevented from being detached from the female connector 10 unless it is caught on the edge and the grip 22 is held.

  A confirmation hole 11 smaller than the engagement hole 12 is formed on the side of each engagement hole 12, and a position between the confirmation hole 11 and the engagement hole 12 on the inner surface of the peripheral wall 10a is shown in FIG. As shown in FIGS. 9 and 11, a fixed engagement piece 13 is provided which is formed in a wall shape extending in the vertical direction and is provided in a state of floating from the bottom wall 10b. When the male connector 20 is accommodated in the recess 10 c, the engagement claw 28 a extending toward the center in the left-right direction of the male connector 20 at the tip of the deformation engagement piece 28 has a lower edge of the fixed engagement piece 13. It is supposed to be caught in.

  As shown in FIG. 11, the presence of the engaging claw 28 a can be confirmed through the confirmation hole 11. As shown in the figure, in the front (back side) of the confirmation hole 11, that is, in the opening direction of the confirmation hole 11, a middle portion of the engagement claw 28a, that is, a portion closer to the root than the tip of the engagement claw 28a is located. The tip of the engaging claw 28 a is not visible from the confirmation hole 11. This makes it difficult to insert a needle or the like from the confirmation hole 11 and release the engagement between the engagement claw 28 a and the fixed engagement piece 13. 9 to 10, the engaging claw 28a extends in the left-right direction along the front surface 20b of the male connector 20, and the clearance between the engaging claw 28a and the front surface 20b of the male connector 20 and the engagement. The gap between the joint claw 28a and the inner surface of the peripheral wall 10a is smaller than the width of the engagement claw 28a. For this reason, even if a needle or the like is inserted from the confirmation hole 11 and the engagement claw 28a is pressed against the back side of the male connector 20, the engagement with the fixed engagement piece 13 cannot be released.

  The engaging claw 28a is formed to be relatively fragile, and no means such as the grip 22 for releasing the engagement with the fixed engaging piece 13 from the outside is provided. Therefore, once the male connector 20 is inserted into the female connector 10 and the engaging claw 28a engages with the fixed engaging piece 13, the grip 22 is again pinched and the male connector 20 is removed from the female connector 10 when The joint claw 28a is bent or can be removed from the tip of the deformation engagement piece 28. In the gaming machine connector according to the present embodiment, since the presence of the engaging claw 28a can be confirmed from the confirmation hole 11, it is confirmed that the male connector 20 is unplugged from the female connector 10 again. Judgment can be made without disconnecting. It should be noted that when the gaming machine is manufactured, not only the fixed engagement piece 13 is provided, but other inspection female connectors having the same configuration as the female connector 10 shown in FIG. The inspection can be performed without damaging the claw 28a.

  Next, as shown in FIG. 4, the side cover member 30 includes a horizontally long rectangular bar-shaped base portion 30 a, and the engagement pieces 31 extend downward from both ends of the base portion 30 a. The engagement piece 31 is cantilevered at the end of the base portion 30a and can be elastically deformed. An engagement claw 31a extending in the width direction of the base portion 30a is provided at the tip, and is formed in an L shape as a whole. Yes. When the side cover member 30 is attached to the male connector 20, the engaging claw 31 a is hooked on the protrusion 23 provided on the side surface of the male connector 20. The upper surface of the protrusion 23 is inclined, and when the side cover member 30 is attached, the engagement claw 31a rides on the protrusion 23, whereby the engagement piece 31 is gradually elastically deformed, and then the engagement piece 31 is engaged. The claw 31a is fitted into the lower side of the protrusion 23.

  A total of 12 elongated plate-like claws 33 extend from the lower surface of the base portion 30 a of the side cover member 30, and these claws 33 are fitted to the sides of the electric wires 60 in the electric wire insertion holes 24, so that the outer sides of the electric wires 60 ( The front side and the back side are filled with the claws 33. Thereby, it is possible to prevent a metal such as a wire from being illegally inserted into the side of the electric wire 60. As shown in FIG. 8, the end of each electric wire 60 is attached with a boss terminal 61 for realizing a reliable electrical connection with the board connection terminal 70, and the tip of the claw 33 is the upper edge of the boss terminal 61. Abut. That is, the claw 33 of the side cover member 30 functions as a retainer for the electric wire 60, and the electric wire 60 is not easily pulled out. Note that the claw 33 is not necessarily in contact with the upper edge of the bullet terminal 61. Of course, even if the claw 33 does not have such a length as to contact the upper edge of the giboshi terminal 61, it is possible to prevent the metal from being illegally inserted into the side of the electric wire 60.

  In addition, twelve semi-cylindrical concave surfaces 32 are formed on one side surface of the base portion 30a so as to match the side surfaces of the twelve electric wires 60 aligned in a row. Thereby, when the side cover member 30 is attached to the male connector 20, the front side or the back side of the electric wire 60 is closed without gaps by the base 30a.

  As shown in FIG. 5, the intermediate cover member 40 also includes a horizontally long rectangular bar-shaped base portion 40a, and engaging pieces 41 extend downward from both ends of the base portion 40a. The engagement piece 41 is cantilevered at the end of the base portion 40a and can be elastically deformed. The engagement claw 41a extending inward at the distal end is hooked on the upper edge of the groove 26 formed on the side surface of the male connector 20. It is like that. On one side surface of the base portion 40a, twelve semi-cylindrical concave surfaces 42 are formed so as to match the side surfaces of twelve electric wires aligned in a row. Similarly, twelve semi-cylindrical concave surfaces 42 are also formed on the opposite side surface. As described above, the twelve concave surfaces 32 are also formed in the base portion 30 a of the side cover member 30, and the concave surface 32 and the concave surface 42 face each other to form the electric wire hole 50. As a result, when the intermediate cover member 40 is attached to the male connector 20, the back side of the row of the electric wires 60 on the front side and the front side of the electric wires 60 on the back side are closed without gaps by both side surfaces of the base portion 40a. .

  An extension 40 b that protrudes laterally and enters between the electric wires 60 is formed below the joint portion of each concave surface 42 in the intermediate cover member 40. That is, as shown in FIG. 7, the base 40a has a convex cross section between the electric wires 60 adjacent in the left-right direction. Further, as shown in the figure, an extension portion 30 b that protrudes laterally and enters between the electric wires 60 is formed on the upper side of the joint portion of each concave surface of the side cover member 30. The extension 30b is located above the extension 40b, so that the intermediate cover member 40 is not easily detached from the male connector 20 unless the side cover members 30 and 30 are removed from the male connector 20. ing.

  As shown in FIG. 1, in a state where the intermediate cover member 40 and the side cover member 30 are attached to the male connector 20, the engagement pieces 41 of the intermediate cover member 40 are formed with protrusions 23 formed on the side surfaces of the male connector 20. 23, and a tip end portion thereof is surrounded by a recess 15 formed on the upper edge of the peripheral wall 10 a of the female connector 10 and engagement pieces 31, 31 of the side cover members 30, 30. Further, the engagement piece 31 extends between the protrusion 23 and the overhanging portion 29 formed on the side surface of the male connector 20, and its distal end is surrounded by the recess 15 and the engagement piece 41 of the intermediate cover member 40. Yes. In this way, it is difficult to remove the side cover member 30 and the intermediate cover member 40 from the male connector 20 by releasing the engagement of the engagement pieces 31 and 41.

  According to the gaming machine connector described above, the periphery of the electric wire 60 is surrounded by the intermediate cover member 40 and the side cover members 30 and 30. At this time, since the claw 33 of the side cover member 30 is fitted into the electric wire insertion hole 24, it is difficult to deform the side cover member 30. Thus, the periphery of the electric wire 60 is reliably covered, and a metal such as a side probe is prevented from being inserted into the electric wire insertion hole 24.

  Further, the deformation engagement piece 28 and the fixed engagement piece 13 are provided in the gap between the male connector 20 and the female connector 10, and when the male connector 20 is attached to the female connector 10, both are engaged. At the same time, since the engagement claw 28a at the tip of the deformation engagement piece 28 can be seen through the confirmation hole 11 provided in the peripheral wall 10a of the female connector 10, the male connector 20 indicates that the male connector 20 has been illegally inserted and removed.
