Description

  The present invention relates to a circuit board storage box of a gaming machine in which an electrical component mounted on a circuit board is appropriately sealed at a portion protruding outward from a component insertion hole formed in a case cover.

A circuit board storage box of a gaming machine has a circuit board on which electrical components constituting a circuit are mounted on a case base that forms one side of the storage box, and a case cover that forms the other side of the storage box A circuit that covers electrical components except those that require external connection or operation, and the case base, circuit board, and case cover are fastened with set screws, and the covering member is exposed to the outside from the case cover A foil-like conductor called a printed wiring on the circuit board, which is attached to the board mounting area and is exposed to the outside from the case cover, protects against fraudulent acts from unsuspecting persons. However, as shown in FIG. 18, the back surface 51 b of the circuit board 51 is entirely covered with the case base 50, but a part of the surface 51 a on which the electrical components 53; 54 of the circuit board 51 are mounted is the case cover 52. It is exposed to the outside without being covered. A component insertion hole 56 is formed in the covering member 55, and when the covering member 55 is covered from above the electrical component 53 in a portion exposed from the case cover 52, the upper part of the electrical component 53 is the component insertion hole. 56, projecting upward from the covering member 55, and the covering member 55 covers a conductor 57 that connects the electrical component 53 exposed from the case cover 52 and the electrical component 54 covered by the case cover 52 (patent) (Refer FIG. 11 of literature 1). However, the outer surface extending upward from the surface 51 a of the circuit board 51 of the electrical component 53 is not a flat surface perpendicular to the surface 51 a of the circuit board 51, but has irregularities 58 in a direction parallel to the surface 51 a of the circuit board 51. It is common. For this reason, when the electrical component 53 not covered with the case cover 52 is inserted into the component insertion hole 56 of the covering member 55 and the covering member 55 is placed on the circuit board 51, the peripheral portion of the component insertion hole 56 and the electrical component There is a gap 59 between them. Therefore, a person who has no heart inserts the rod-shaped unauthorized operation member 60 into the internal space 61 covered with the case cover 52 from the gap 59, and the conductor 57 not covered with the electrical component 54 or the covering member 55 in the internal space 61. There was the disadvantage of cheating. Further, as shown in FIG. 19, a covering portion 62 is provided on the electric component 53 exposed from the case cover 52, and the electric component 53 where the covering portion 62 is exposed from the case cover 52 and the electric component 54 covered with the case cover 52, (See FIG. 18 of Patent Document 1). For this reason, a person who has no heart inserts the rod-shaped unauthorized operation member 60 into the internal space 61 covered with the case cover 52 from the gap 63 formed between the circuit board 51 exposed from the case cover 52 and the case cover 52. There has been a drawback that an act of fraud is performed on the electrical component 54 and the conductor 57 in the internal space 61. In the structure shown in FIGS. 18 and 19, a part of the surface 51 a on which the electrical component 53; 54 of the circuit board 51 is mounted is exposed to the outside from the case cover 52, and the covering member 55 or the covering portion 62 is the case cover 52. The surface 51a on which the electrical components 53; 54 of the circuit board 51 are mounted is entirely covered with the case cover 52 only by covering the conductor 57 that connects the electrical component 53 exposed from the electrical component 54 and the electrical component 54 covered with the case cover. Since it is not covered, the electric component 54 and the conductor 57 in the internal space 61 covered with the case cover 52 have a disadvantage of being subjected to fraud.

The terminal insertion hole 8 penetrates through the front surface 3 a and the back surface 3 b of the circuit board 3. At four corners of the circuit board 3, attachment holes 9 penetrate the front surface 3 a and the back surface 3 b of the circuit board 3. The connector 7 projects a plurality of electrical connection terminals 11 downward from the bottom surface of the connector body 10 as a component body made of synthetic resin. When the connector 7 is mounted on the circuit board 3, the electrical connection terminals 11 are inserted into the terminal insertion holes 8 from the surface 3 a side of the circuit board 3. In the connector 7, the covering member 4 protrudes integrally from the side surface of the connector body 10 to the outside.

  The structure of the case base 1 will be described with reference to FIGS. 3 and 4. The case base 1 includes a base substrate 15, a side wall 16, a support base 17, an engagement portion 18, a receiving hole 19, a protrusion 20, and a fixing portion 21, which are made of colorless synthetic resin having a property of transmitting light. It is a structure formed into a shape. The base substrate 15 is a square larger than the case cover 2. The side wall 16 is one of the plate surfaces of the base substrate 15 in one direction as a direction facing the case cover 2 of FIG. 2 from a pair of peripheral edges facing each other on the base substrate 15 and one peripheral edge located on the right side. It protrudes so as to be perpendicular to the surface 15 a and is connected to each other in the circumferential direction of the base substrate 15. When the case base 1 and the case cover 2 are combined by lateral movement, the support base 17 is a portion that receives the back surface 3b of the circuit board 3 and is directed from the side wall 16 in a direction facing the front surface 15a of the base board 15. Protruding.

  A gap between the side wall 16 and the support base 17 is formed as a take-in groove 22 that accommodates the side wall of the case cover 2. When the case base 1 and the case cover 2 are combined by lateral movement, the engaging portion 18 covers a surface 26 a that is one of the plate surfaces of the cover substrate 26 in the case cover 2 housed in the take-in groove 22. The receiving hole 19 is provided in the side wall 16 located on the right side that exists in the direction orthogonal to the lateral movement when the case base 1 and the case cover 2 are combined with each other, and the case base 1 and the case cover 2 are moved by the lateral movement. When they are combined, they are fitted with the protrusions 35 of the case cover 2. The protrusion 20 protrudes to the left from the left edge portion facing the one side wall 16 of the base substrate 15. When the case base 1 and the case cover 2 are combined by lateral movement, the protrusion 20 is fitted with the receiving hole 34 of the case cover 2. The The fixing part 21 is a part for fixing the case base 1 and the case cover 2 combined with each other in an inseparable manner, and protrudes outward from one side wall 16 of the pair of side walls 16 facing each other, for example. The fixing portion 21 includes a plurality of recessed fixing portion portions 23 that are recessed.

  The structure of the case cover 2 will be described with reference to FIGS. The case cover 2 is made of a colorless synthetic resin having a property of transmitting light, and includes a cover substrate 26, a side wall 27, a main bulge portion 28, a sub bulge portion 29, a substrate attachment portion 30, a component insertion hole 31, a rib 32, This is a structure formed in an integral shape, including a notch 33, a receiving hole 34, a protrusion 35, a fixing portion 36, and a device mounting portion 37. As shown also in FIG. 6, the cover substrate 26 has a larger square shape than the circuit board 3. The side wall 27 protrudes in a direction facing the case base 1 from the cover substrate 26 rather than the surface 26 a of the cover substrate 26, and is connected to the circumferential direction of the cover substrate 26. The square opening surrounded by the side walls 27 connected to each other is a square larger than the circuit board 3.

  The main bulging portion 28 and the sub bulging portion 29 form a recess that protrudes from the back surface 26b of the cover substrate 26 toward the front surface 26a. When the case cover 2 and the circuit board 3 are combined with each other, the main bulging portion 28 forms an internal space that opens to the case base 1 that covers the electrical component 6 that is mounted on the circuit board 3 except for the connector 7. To do. When the case cover 2 and the circuit board 3 are combined with each other, the auxiliary bulging portion 29 forms an internal space that opens to the side of the case base 1 that covers the connector 7 and the covering member 4 mounted on the circuit board 3. . The component insertion hole 31 is an opening for projecting the connector 7 mounted on the circuit board 3 from the case cover 2 to the outside when the case cover 2 and the circuit board 3 are combined with each other. Are individually provided in the sub-bulge portion 29 so as to protrude from the component insertion holes 31 individually. The rib 32 has an annular shape that protrudes from the periphery of the component insertion hole 31 into the sub-bulged portion 29 and is connected in the circumferential direction of the component insertion hole 31.

  When the case base 1 and the case cover 2 are combined by lateral movement, the notch 33 is a portion that escapes the pair of side walls 16 that face each other in the case base 1. The receiving hole 34 is provided in the left side wall 27 that exists in a direction orthogonal to the lateral movement when the case base 1 and the case cover 2 are combined with each other, and the case base 1 and the case cover 2 are combined by lateral movement. In this case, it is fitted to the protrusion 20 of the case base 1. Since the protrusion 35 exists in a direction orthogonal to the lateral movement when the case base 1 and the case cover 2 are combined with each other, the protrusion 35 projects outward from the right side wall 27, and the case base 1 and the case cover 2 are combined by the lateral movement. If fit, it is fitted into the receiving hole 19 of the case cover 2. The fixing portion 36 is a portion for fixing the case base 1 and the case cover 2 combined with each other in an inseparable manner, and one side wall 27 so as to be positioned in the same direction as the fixing portion 21 of the case base 1. Projecting outwards. The fixed portion 36 includes a plurality of fixed portion portions 38. Inside the fixing portion 38, fixing screws (not shown) are individually stored.

  With reference to FIG. 8, the structure of the connector 7 provided with the coating | coated member 4 is demonstrated. The covering member 4 includes a covering substrate 40 and a peripheral wall 41, and has a structure formed in a shape integral with the connector body 10 from a synthetic resin. The coated substrate 40 is disposed in the internal space of the sub-bulged portion 29 and has a square shape larger than the component insertion hole 31 that surrounds the side surface of the connector body 10 in the circumferential direction. The peripheral wall 41 protrudes in one direction as a direction facing the case cover 2 from the periphery of the coated substrate 40, and has a ring shape connected to the circumferential direction of the coated substrate 40.

  A method of assembling the circuit board storage box will be described with reference to FIGS. First, as shown in FIG. 9a, the electrical connection terminal 11 of the connector 7 is inserted into the terminal insertion hole 8 of the circuit board 3, and the bottom surface of the connector body 10 is placed on the surface 3a of the circuit board 3 and comes into contact therewith. The tip of the electrical connection terminal 11 protrudes outward from the bumps 14 around the terminal insertion holes 8 in the circuit board 3. The bump 14 is a portion provided on the circuit board 3 for attaching the solder 43 with a foil-like conductor made of the same material as a conductor such as a printed wiring.

  By attaching the solder 43 to the tip of the electrical connection terminal 11 protruding from the bump 14 and the bump 14, the connector 7 is inserted and mounted in such a manner that the covering member 4 is separated from the circuit board 3. When the solder 43 is applied, the covering member 4 is lifted upward from the circuit board 3, so that heat when the solder 43 is applied is not deprived by the covering member 4, and the covering substrate 40 and the circuit board 3 Since it does not stay in the gap and escapes appropriately from the gap to the outside of the coated substrate 40 and the circuit board 3, the electrical connection terminals 11 and the bumps 14 are good with the solder 43 as in the case where the coated substrate 40 does not exist. It is attached to. Even if the connector 7 and the covering member 4 shown in FIG. 9a are mounted on the circuit board 3 simultaneously with the electrical component 6 except the connector 7 shown in FIG. 2, the connector 7 shown in FIG. It may be performed after mounting the electrical component 6 except for the mounting, or may be performed before mounting the electrical component 6 except the connector 7 shown in FIG.

  Thereafter, the case cover 2 is turned over so that the opening surrounded by the side wall 27 in the case cover 2 is directed upward, and the circuit board 3 is turned over so that the connector 7 and the electrical component 6 are directed downward. The front surface 3 a of the substrate 3 and the back surface 21 b of the cover substrate 26 face each other, and the circuit substrate 3 is stored in the internal space of the case cover 2. As a result, as shown in FIG. 9 b, the tip of the connector 7 penetrates the component insertion hole 31 of the case cover 2 and protrudes outward from the internal space of the auxiliary bulging portion 29, so that the mounting hole 9 of the circuit board 3 is provided. Is fitted into the board mounting portion 30 of the case cover 2, and the peripheral edge of the circuit board 3 is mounted on the back surface 26 b of the cover board 26. That is, since the mounting hole 9 of the circuit board 3 and the board mounting portion 30 of the case cover 2 are fitted to each other, the circuit board 3 can be attached to the case cover 2 without using a fixing tool such as a set screw. Assembling and disassembling of the circuit board 3 is easy. Accordingly, the main bulging portion 28 of the case cover 2 covers and hides the electrical component 6 except the connector 7, the rib 32 of the case cover 2 is fitted inside the peripheral wall 41 of the covering member 4, and the rib 32 is formed on the covering member 4. The auxiliary bulging portion 29 covers and hides the outer periphery of the peripheral wall 41 of the covering member 4 so as to come into contact with the covering substrate 40 or to face each other.

  Next, as shown in FIG. 10 a, the opening surrounded by the side wall 16 of the case base 1 and the opening surrounded by the side wall 27 of the case cover 2 face each other, and the left side wall 16 of the case base 1. And the right side wall 27 of the case cover 2 are brought close to each other. Then, the case base 1 and the case cover 2 are fitted together so that the notch 33 of the case cover 2 takes in the support base 17 of the case base 1 and the pair of side walls 16 facing each other. In this case, the circuit board 3 is received by the support base 17 of the case base 1.

  Thereafter, with the case base 1 and the case cover 2 being aligned with each other, the case base 1 is laterally moved toward the left side as indicated by the arrow X2, and the case cover 2 is laterally directed toward the right side as indicated by the arrow X1. Moved. Only one of these lateral movements may be used. Accordingly, the engaging portion 18 covers the surface 26a of the cover substrate 26 on the side of the pair of side walls 16 facing the case cover 2, and the receiving hole 19 of the case base 1 and the protrusion 35 of the case cover 2 are fitted together. The protrusion 20 of the case base 1 and the receiving hole 34 of the case cover 2 are fitted together. Thus, the circuit board 3 is sandwiched and supported by the support base 17 and the cover board 26. Then, the inner surface of the right side wall 16 in the case base 1 and the outer surface of the right side wall 27 in the case cover 2 are abutted against each other, so that the fixed portion 21 and the fixed portion 36 face each other. Thereafter, a fixing screw (not shown) of one fixed location 38 located on the leftmost side of the case cover 2 is fastened to one fixed location 23 located on the leftmost side of the case base 1 with a fastening tool such as a screwdriver. . As a result, as shown in FIG. 10b, the case base 1 and the case cover 2 cannot be separated from each other.

  According to the circuit board storage box in the best mode, as shown in FIG. 1, the covering member 4 is integrally provided on the connector body 10 in order to block the gap 44 between the connector 7 and the component insertion hole 31 as a whole. The covering member 4 has a structure including a cover side extending portion 45. For this reason, even if the unauthorized operation member 46 is inserted into the gap 44 from the outside of the storage box composed of the case cover 2 and the case base 1, the covering member 4 prevents the unauthorized operation member 46 from entering the closed space 37. Accordingly, the connector 7 with the covering member 4 mounted on the circuit board 3 is appropriately sealed off from the part insertion hole 31 formed in the case cover 2 and protruding to the outside of the case cover 2, and the unauthorized operation member 46 is closed space. There is an advantage that the foil-like conductor and the electrical component 6 in the circuit board 3 that connects the electrical component 6 and the connector 7 in the closed space 37 are not subjected to fraudulent activity without intruding into the closed space 37. Since the covering member 4 is provided integrally with the connector body 10, the covering member 4 is mounted on the circuit board 3 by mounting the connector 7 on the circuit board 3. Therefore, the covering member 4 and the connector 7 are separated from each other. Thus, there is no need to mount the cover member 4 on the circuit board 3, and it is not necessary to bond, bond, or fix the cover member 4 to the circuit board 3 with a set screw. There is an advantage that it becomes easy.

  Since the covering substrate 40 of the covering member 4 and the rib 32 constituting the peripheral portion of the component insertion hole 31 in the case cover 2 are in contact with each other or approaching each other, the unauthorized operation member 46 enters the closed space 37. There is an advantage that can be prevented more satisfactorily. The case cover 2 includes a rib 32 that protrudes in the direction of the covering member 4 from the peripheral edge of the component insertion hole 31, the covering member 4 includes a peripheral wall 41 that protrudes in the direction of the case cover 2, and the rib 32 is located inside the peripheral wall 41. Since the rib 32 and the peripheral wall 41 are fitted to each other so that the peripheral wall 41 surrounds the outside of the rib 32, the unauthorized operation member 46 enters between the rib 32 and the coated substrate 40 through the gap 44. However, there is an advantage in that it can reach the peripheral wall 41 and cannot enter between the rib 32 and the peripheral wall 41, and the unauthorized operation member 46 can be more effectively prevented from entering the closed space 37.

  FIG. 11 shows a side surface in which a connector 7 having a covering member 4 in another form is partially cut away. The covering substrate 40 of the covering member 4 has a square shape larger than the component insertion hole 31 that protrudes outward from the lower portion of the connector body 10 and surrounds the side surface of the connector body 10 in the circumferential direction. Thereby, the covering substrate 40 can be brought close to the circuit board 3, and the height of the sub-bulged portion 29 from the circuit board 3 can be reduced.

  12 to 14 show still another form. FIG. 12 shows the appearance of the connector 7 provided with the covering member 4. FIG. 13 shows a side surface in which the connector 7 having the covering member 4 is partially cut away. FIG. 14 shows a process of mounting a plurality of connectors 7 including the covering member 4 on the circuit board 3. In FIG. 12, the covering member 4 has a rectangular plate shape that protrudes outward from the side surface from the connector body 10 and surrounds the side surface of the connector body 10 in the circumferential direction. The pair of side portions facing each other in the covering member 4 are provided with cut portions 48 and 49 alternately. That is, the one cut portion 48 is provided in a stepped shape that is recessed from the surface 4 a of the covering member 4 to the inside. The other excision 49 is provided in a stepped shape that is recessed from the back surface 4 b of the covering member 4. The cut portions 48; 49 are opened to a pair of side surfaces 4c: 4d that face each other in the covering member 4.

  14, a case where a plurality of, for example, three connectors 7 shown in FIGS. 12 and 13 are mounted on the circuit board 3 will be described. First, as shown in FIG. 14 a, the cutout portion 49 of the covering member 4 is directed toward the circuit board 3, and the cutout portion 48 of the covering member 4 is directed toward the side away from the circuit board 3. The connector 7 is inserted and mounted on the circuit board 3 and attached to the bumps 14 with solder 43. Next, as shown in FIG. 14B, the second connector 7 is inserted and mounted on the circuit board 3 and attached to the bumps 14 with solder 43. In this case, the cut portion 49 of the covering member 4 in the second connector 7 is overlapped with the cut portion 48 of the covering member 4 in the first connector 7. Thereafter, as shown in FIG. 14c, the cutout portion 49 of the covering member 4 in the third connector 7 is overlapped with the cutout portion 48 of the covering member 4 in the second connector 7, and the third connector 7 is inserted and mounted on the circuit board 3 and attached to the bumps 14 with solder 43. As a result, the covering members 4 of the three connectors 7 are formed in a single plate shape connected in series in the direction in which the connectors 7 are arranged.

  Therefore, although the order of mounting the plurality of connectors 7 is restricted, the component insertion holes 31 in the case cover 2 do not have to be independent for each of the plurality of connectors 7, and all of the plurality of connectors 7 are combined into one component insertion hole 31. There is an advantage that it can be formed in a simple shape of an elongated rectangular shape protruding from the shape.

  FIG. 15 shows still another form. As shown in FIG. 15a, a sub-cover member 47 formed separately from the cover member 4 provided integrally with the connector body 10 is provided. The sub-cover member 47 has a plate surface larger than the diameter of one component insertion hole 31 for inserting all of the plurality of connectors 7 in the case cover 2 and transmits light made of an elastic material such as synthetic resin or rubber. It is a plate shape with the property to do. The sub coating member 47 is provided with a plurality of through holes 47a. The hole diameter of the through hole 47 a is such that the connector bodies 10 of the plurality of connectors 7 mounted on the circuit board 3 are individually inserted, but is smaller than the outer shape of the covering member 4. The covering member 4 has a plate shape protruding outward from the connector body 10 and has a form in which the peripheral wall 41 shown in FIG. 8 is deleted, but a form in which the peripheral wall 41 is provided may be used.

  Then, in a state in which the plurality of connectors 7 are mounted on the circuit board 3, the sub-covering member 47 is put on all of the plurality of connectors 7, and the direction away from the circuit board 3 rather than the covering member 4 in all of the plurality of connectors 7. When the upper part of the connector body 10 protruding in the direction is individually inserted into the through hole 47a of the sub-coating member 47, the upper part of the connector body 10 in the plurality of connectors 7 projects above the sub-coating member 47 from the through hole 47a. The periphery of the through-hole 47a in the covering member 47 comes into contact with the covering member 4 and covers the covering member 4. Thereafter, the case cover 2 is placed on the circuit board 3 from above the connector 7, and the upper portions of the connector bodies 10 of the plurality of connectors 7 protruding upward from the sub-cover member 47 protrude above the case cover 2 from the component insertion holes 31. The rib 32 of the case cover 2 comes into contact with the upper surface of the sub-coating member 47. As a result, as shown in FIG. 15 b, the sub-cover member 47 is formed so that the gaps between the cover members 4 in the plurality of connectors 7 mounted on the circuit board 3, the ribs of the plurality of connectors 7 and the component insertion holes 31. Close the gap with 32. For this reason, there exists an advantage that the some connector 7 can be mounted in the circuit board 3 so that a clearance gap may be formed between the coating | coated members 4. FIG. The sub-cover member 47 and the case cover 2 are separately covered on the circuit board 3. However, the sub-cover member 47 is integrally bonded to the case cover 2 with an adhesive, and the case cover 2 including the sub-cover member 47 is connected to the circuit board 3. The substrate 3 may be covered. If the sub-coating member 47 is used as in this embodiment, even if the number of the plurality of connectors 7 mounted on the circuit board 3 or the mounting interval between the plurality of connectors 7 changes due to model exchange. By forming the component insertion hole 31 formed in the case cover 2 in a size that can be used in common between different models, the case cover can be obtained simply by replacing the circuit board 3 and the sub-coating member 47. There is an advantage that 2 can be used in common.

  FIG. 16 shows still another form. As shown in FIG. 16a, the covering member 4 and the connector body 10 are formed separately. The covering substrate 40 of the covering member 4 is formed with a recess 40a for accommodating the lower part of the connector body 10, and a through hole 40b for inserting the electrical connection terminal 11 is formed at the bottom of the recess 40a. Then, as shown in FIG. 16b, the electrical connection terminal 11 is inserted into the through hole 40b from above the covering member 4 and protrudes downward from the covering substrate 40, and the lower part of the connector body 10 is accommodated in the recess 40a. Then, the covering member 4 is provided integrally with the connector 7 by being fixed with the adhesive 40c.

  FIG. 17 shows still another form. As shown in FIG. 17a, the covering member 4 and the connector body 10 are formed separately. The covering substrate 40 of the covering member 4 is formed with a recess 40a for accommodating the lower part of the connector body 10, and a through hole 40b for inserting the electrical connection terminal 11 is formed at the bottom of the recess 40a. Then, as shown in FIG. 17b, the electrical connection terminal 11 is inserted into the through hole 40b from above the covering member 4 and protrudes downward from the covering substrate 40, and the lower part of the connector body 10 is accommodated in the recess 40a. Then, the covering member 4 is provided integrally with the connector 7 by being fixed with the adhesive 40c. The difference between FIG. 16 and FIG. 17 is that the recess 40a in FIG. 16 is deeper than the recess 40a in FIG. Therefore, the difference is that the covering substrate 40 of the covering member 4 in FIG. 16 is located in the middle of the connector body 10 in the vertical direction, whereas the covering substrate 40 of the covering member 4 in FIG. . Instead of fitting the covering member 4 into the connector body 10 and fixing it with the adhesive 40c, it may be fixed by joining or a set screw.

  Although not shown, a foil-like conductor called a printed wiring that connects the electrical component 6 and the connector 7 on the circuit board 3 may be provided on one or both of the front surface 3 a and the back surface 3 b of the circuit board 3. If the lower surface of the rib 32 and the surface 3a of the circuit board 3 are in contact with each other or approach each other, and the unauthorized operation member 46 cannot enter between the lower surface of the rib 32 and the surface 3a of the circuit board 3, The member 4 may not be provided with the peripheral wall 41. The peripheral wall 41 does not exist in the covering member 4, the rib 32 does not exist in the peripheral portion of the component insertion hole 31, and the lower surface of the peripheral portion of the component insertion hole 31 and the surface 3 a of the circuit board 3 come into contact with or contact each other. You may make it approach a grade. It is not a structure in which the case base 1 and the case cover 2 are combined by lateral movement, but a structure in which the case base 1 and the case cover 2 are fitted with each other like a lunch box lid and a container and then joined with a set screw. The fixing part 21 and the fixing part 36 that fix the case base 1 and the case cover 2 in a non-separable manner may be omitted.
