Description

  The present invention relates to a connector cover. Conventionally, a board connector is used to connect a cable to a circuit board such as a printed circuit board. Such a board connector is mounted on a circuit board and is fitted with a cable connector connected to an end of the cable.

  By the way, in recent years, there has been an increase in fraudulent acts of bringing a probe such as a wire or a needle into contact with a terminal of a board connector connected to a circuit board of a gaming machine such as a pachislot machine, a combination of a pachinko machine and a slot machine. is doing. In such a fraudulent act, a fraudulent signal is sent to the signal circuit of the gaming machine, thereby illegally operating the gaming machine. For this reason, the probe is often inserted between the lower end edge of the side surface of the board connector attached to the circuit board and the surface of the circuit board, and the probe is brought into contact with the terminal protruding from the bottom surface of the board connector.

  Therefore, in order to prevent such illegal acts, a sheet-shaped or plate-shaped resin fraud prevention lid (lid) plate may be attached around the lower edge of the side surface of the board connector attached to the circuit board. Proposed. Covering the periphery of the lower end edge of the board connector side surface with a predetermined size, for example, a fraud prevention cover plate having a thickness of about 0.2 [mm] or more, the lower end edge of the board connector side surface and the circuit board surface It is possible to prevent the probe from being inserted in between.

  The fraud prevention cover plate is attached to the circuit board so as to cover the circuit board surface around the board connector after the board connector is attached to the circuit board. In such prior art, the fraud prevention cover plate has an opening surrounding the periphery of the board connector, and is attached to the circuit board so that the board connector passes through the opening. .

  However, since an inevitable gap is formed between the inner edge of the opening and the periphery of the board connector, the probe may be inserted from the gap. Therefore, a technique has been proposed in which a shielding member that surrounds the board connector and closes the gap is attached to a circuit board (see, for example, Patent Document 1).

  FIG. 6 is a cross-sectional view of a conventional board connector. In the figure, reference numeral 801 denotes a circuit board provided with conductive traces, on which a board connector 802 is mounted. The board connector 802 is fitted with a cable connector connected to a cable (not shown). A fraud prevention cover plate 803 is attached above the circuit board 801 so as to cover the surface of the circuit board 801. The fraud prevention lid plate 803 has an opening, and is attached to the circuit board 801 so that the board connector 802 is passed through the opening.

  Further, a shielding member 805 surrounding the periphery of the board connector 802 is attached to the circuit board 801. The fraud prevention lid plate 803 includes a cylindrical portion 804 that extends downward and connected to the edge of the opening, and the cylindrical portion 804 is fitted into a groove 806 formed in the shielding member 805.

  In the prior art, since the gap between the opening of the fraud prevention lid plate 803 and the periphery of the board connector 802 is blocked by the shielding member 805, a probe is inserted from the gap to the terminal protruding from the bottom surface of the board connector 802. It is possible to appropriately prevent an illegal act of bringing the probe into contact.

JP 2006-81714 A

  The present invention has the knowledge that the conventional technique using the conventional shielding member 805 cannot sufficiently cope with the fraud. By inserting the cylindrical portion 804 of the tamper-proof cover plate 803 into the groove 806, a gap is not generated between the periphery of the board connector and the tamper-proof cover plate 803. Therefore, the shielding member 805 is provided. This makes the structure complicated and difficult to manufacture. In addition, the fraud preventing lid plate 803 also needs to connect a cylindrical portion 804 extending downward to the edge of the opening. This makes the structure more complex and more difficult to manufacture.

  Furthermore, in the conventional fraud prevention technology, the inner peripheral surface of the shielding member 805 needs to be in close contact with the outer peripheral surface of the board connector 802. In general, the outer peripheral surface of the board connector 802 is not a flat surface but has irregularities caused by manufacturing errors. In consideration of such unevenness, it is necessary to form the inner peripheral surface of the shielding member 805 in a shape suitable for the unevenness of the outer peripheral surface of the board connector 802, which makes manufacturing more difficult and increases the cost. However, if the inner peripheral surface of the shielding member 805 is not in close contact with the outer peripheral surface of the board connector 802, the insertion of the probe cannot be prevented appropriately as shown in FIG.

  The present invention has been made to solve the problems of the connector cover of the prior art. The present invention solves these problems by using a connector cover that surrounds at least the vicinity of the board-side end of the connector mounted on the board. The connector cover of the present invention has side walls with multiple structures, so that each part can be elastically deformed, and the side walls can be in close contact with the outer peripheral surface of the connector and the lower surface of the lid plate while having a simple structure. Compared with the configuration of the prior art, the manufacturing is easy and the manufacturing cost is low. The present invention also provides an improved connector cover that can be repeatedly attached and detached.

  For this purpose, the connector cover of the present invention is a connector cover having a main body portion surrounding the periphery of the board side of the connector mounted on the substrate, and the main body portion includes an upper side wall and a multiple structure side wall. The side wall is opened on the board side of the main body, and the main body is integrally connected to the upper side wall on the opposite side, and the innermost side wall of the side wall is located on the board end side of the board connector. Close to the outer surface.

  In another connector cover of the present invention, the connector cover has a main body portion surrounding the periphery of the vicinity of the board-side end of the connector mounted on the opposing substrate. The cover for the connector is at least partially covered with a cover plate, the cover plate includes an opening surrounding the periphery of the connector for the board, and the main body includes an upper side wall and a multi-structure side wall, and the upper side wall Is in contact with the outer peripheral portion of the opening on the side surface of the cover plate, and the innermost wall element of the side wall is in close contact with the outer peripheral surface between the cover plate and the substrate in the connector.

  In another connector cover of the present invention, the multiple structure side wall is a double structure composed of an outer wall element and an inner wall element, and the upper ends of the outer wall element and the inner wall element are connected to the upper wall. It is connected.

  In still another connector cover of the present invention, the multiple structure side wall further includes a portion defining a hollow portion in the body of the connector cover between the outer wall element and the inner wall element.

  In still another connector cover according to the present invention, the inner wall element is at least one slit, extends in the vertical direction, and one end is opened at the lower end of the inner wall portion. With slits to increase flexibility.

  In still another connector cover of the present invention, the main body portion further includes a connecting rib for connecting the outer wall element and the inner wall element.

  In still another connector cover of the present invention, the main body portion further includes a projection for closing the opening of the connector.

  In still another connector cover of the present invention, the main body portion further includes at least one locking claw (claw) or a projection for locking the positional relationship between the connector and the connector cover.

  In still another connector cover of the present invention, the upper side wall has a flat surface on the lid plate side.

  According to the present invention, the connector cover surrounds at least the entire periphery of the board connector and has multiple side walls. Accordingly, the connector cover having a deformable characteristic, which has an elastically deformable portion and a structure that is in close contact with the outer peripheral surface of the connector and can be adapted to the outer peripheral surface of the connector that is not necessarily flat and may include irregularities. Is provided. Thereby, the connector cover can be brought into close contact with the lower surface of the cover plate. Further, the connector cover is easy to manufacture, is low in cost, and can be repeatedly attached and detached.

  The details of the embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are merely examples of the present invention, and that the present invention can be variously modified. Accordingly, the specific details described herein are not to be construed as limiting, but are merely a basis for understanding the claims, and those skilled in the art can implement the present invention in various modifications. It is merely a representative basic example, and includes various features disclosed in combinations not explicitly described here.

  In the figure, reference numeral 31 denotes a connector cover according to the present embodiment, which is attached so as to surround the vicinity of the end on the board 91 side of the board connector 1 as a connector mounted on the board 91 described later. The board connector 1 is a so-called straight type receptacle connector, which extends perpendicularly to the board 91, has an internal opening facing upward, and the mating connector 101 shown in FIG. This is a connector of a type in which the fitting direction is perpendicular to the substrate 91. The connector cover 31 is attached so that the lower end in FIG. 1 is in contact with the surface of the substrate 91. FIG. 2 shows a state in which the connector cover 31 is reversed with respect to the mounting direction.

  The board connector 1 and the mating connector 101 may be used for any purpose. In the present embodiment, the board connector 1 and the mating connector 101 are preferably used for gaming machines such as pachinko and pachislot machines. It is assumed that the board 91 is typically a printed circuit board of a gaming machine. For gaming machines, for example, probes (171, 172, and 173 in FIG. 5) are inserted from the bottom edge of the side surface of the board connector 1 and the surface of the board 91, and protrude from the bottom surface of the board connector 1. Since an illegal act of sending an illegal signal to the signal circuit of the gaming machine is performed by bringing the probe into contact with a terminal 61 which will be described later, a lid plate 92 which will be described later is attached to the substrate 91 in order to prevent the illegal act. It is attached so as to cover at least a part.

  Since various electric devices, electronic devices, and the like are mounted on the surface of the substrate 91, the lid plate 92 is attached so as to have a predetermined interval between the surface of the substrate 91. Further, the lid plate 92 includes an opening 93 that surrounds the periphery of the board connector 1, and is attached to the board 91 so that the board connector 1 passes through the opening 93.

  However, since an inevitable gap is generated between the inner edge of the opening 93 and the periphery of the board connector 1, there is a possibility that a probe is inserted from the gap and an illegal act is performed. Therefore, by attaching the connector cover 31 so as to surround the vicinity of the end of the board connector 1 on the board 91 side, the probe is inserted from the gap to prevent unauthorized actions. Yes.

  In the present embodiment, the upper, lower, left, right, front, rear, etc. directions are used to explain the configuration and operation of each part of the connector cover 31, the board connector 1, and the mating connector 101. The expression indicating is not relative but relative, and is appropriate when the connector cover 31, the board connector 1, and the mating connector 101 are in the posture shown in the figure. 31. When the postures and orientations of the board connector 1 and the mating connector 101 are changed, they should be interpreted according to changes in the posture and orientation.

  In the present embodiment, the connector cover 31 is a member that is integrally formed of an insulating material such as synthetic resin. The connector cover opening 32 and the periphery of the connector storage opening 32 are surrounded by the connector cover opening 32. It has the main-body part 33 as a surrounding continuous wall member. The main body 33 shown in the figure is a substantially “mouth” -shaped member connecting two sets of opposing linear wall members, and defines the outer periphery of the connector receiving opening 32. The connector housing opening 32 penetrates the main body 33 in the thickness direction, that is, in the vertical direction.

  The connector cover 31 exhibits flexibility due to the structural features and / or materials described herein. Typically, structural features are more important in obtaining properties for preventing fraud. The material is typically a synthetic resin that has elasticity and compressibility, exhibits sufficient rigidity as well as flexibility, and does not impair features that prevent fraud due to structure. Examples of synthetic resins useful in this regard are, for example, acrylonitrile-butadiene-styrene (ABS) resins, acrylonitrile-styrene (AS) resins, nylon or other polyamides, relatively hard copolymers, and the like.

  The main body 33 has a multiple structure including two side walls 34 surrounding the connector housing opening 32. In other words, multiple side walls 34 are provided. The number of wall elements constituting the side wall 34 may be two or more. For example, the number of wall elements on each side wall 34 may be three or four for convenience of explanation. 2 and the case where the main body 33 has a double structure will be described. In this case, the main body 33 has an outer wall element 34a as the outermost wall element and an inner wall element 34b as the innermost wall element, as best shown in FIG. Each of the outer wall element 34a and the inner wall element 34b is a substantially “mouth” -shaped member in which two pairs of opposing linear rectangular plate members are connected.

  Moreover, the main-body part 33 has the upper side wall 35 which connects the upper end of the outer side wall element 34a and the inner side wall element 34b, as FIG. 1 shows. The upper surface of the upper side wall 35 is substantially flat and contacts the side surface of the substrate 91 of the lid plate 92, that is, the lower surface. The side edges on both sides of the upper side wall 35 are integrally connected so as to be substantially orthogonal to the upper end edges of the outer wall element 34a and the inner wall element 34b. Thereby, since only the upper end is connected to the upper side wall 35 and the lower end is free, the outer wall element 34a and the inner wall element 34b can be elastically deformed flexibly.

  In the present embodiment, as shown in FIG. 2, a connecting rib 39 that connects the outer wall element 34a and the inner wall element 34b is provided at a portion corresponding to the middle of the opposing long side of the main body 33. Is formed. The connecting rib 39 extends in the vertical direction, and side edges on both sides are connected to the outer wall element 34a and the inner wall element 34b. Therefore, each of the outer wall element 34a and the inner wall element 34b is restrained by the connecting rib 39, so that the flexibility is lowered and it is difficult to deform. This is because the outer wall element 34a and the inner wall element 34b are elongated plate-shaped at the portions corresponding to the opposing long sides of the main body 33, and the rigidity is reduced. For this reason, when the flexibility is excessive, it is advantageous to reduce the flexibility. That is, by appropriately disposing the connecting rib 39, the outer wall element 34a and the inner wall element 34b can be adjusted to be less flexible. The number of the connecting ribs 39, the locations where the connecting ribs 39 are disposed, the thickness, and the like are set as appropriate, so that the outer wall element 34a and the inner wall element 34b can be flexed without impairing the object of the present invention. It can be appropriately adjusted so that the property is at a desirable level.

  Further, in the present embodiment, as shown in FIGS. 1 and 2, a slit 41 that cuts a part of the inner wall element 34 b is formed in a portion corresponding to the middle of the opposing short side of the main body 33. ing. The slit 41 extends in the vertical direction, and one end is opened at the lower end of the inner wall element 34b. Therefore, since the inner wall element 34b is divided by the slit 41, the flexibility is improved and the inner wall element 34b is more easily deformed.

  This is because the inner wall element 34b has a short rectangular shape in which the left and right sides are constrained at the portion corresponding to the opposing short side of the main body 33, so that if there is no slit 41, the inner wall element 34b This is because the rigidity of this portion becomes too high, and the flexibility becomes lower than that required for the work. Adding a slit improves flexibility. Therefore, by forming the slit 41, the end of the inner wall element 34b and the flexibility of the entire inner wall element 34b can be adjusted. The flexibility of the inner wall element 34b can be adjusted as appropriate by appropriately setting the number of the slits 41, the portions to be formed, the length, the width, and the like as necessary. Further, if necessary, by forming the slit 41 in the outer wall element 34a, it is possible to adjust the outer wall element 34a to be highly flexible, whereby the outer wall element 34a and the connector cover 31 can be adjusted. The flexibility of the multiple side walls 34 can be increased.

  Engagement projections 37 are formed on the inner wall element 34 b of the side wall 34. The engagement convex portion 37 engages with a concave portion 19 formed in the housing 11 described later of the board connector 1. Further, it engages with a slot-shaped opening 12 formed in the housing 11 so as to close the opening 12 or a closing protrusion 38 as an ear, and a protrusion 18 formed in the housing 11. Engaging recesses 44 that fit together, and ridges 42 that engage with the recessed grooves 17 formed in the housing 11 are formed. Each of the closing projections 38 has a flange 45 formed in the vicinity of the end thereof, protrudes outward, and is accommodated in the opening 12 of the housing 11. Thereby, the upper limit of compression of the connector cover 31 can be set.

  The various protrusions formed on the inner side of the connector cover 31 are accommodated in the various slot-like openings of the board connector 1 when the connector cover 31 and the board connector 1 are connected, and the interference fits. provide. This is explained by a protrusion having a shape called a “lock claw protrusion”. A first lock claw 36a and a third lock claw 36c are formed in the inner wall element 34b, and each engages or enters a lock hole (opening) 16 formed in the housing 11 and opens to the connector. The positional relationship between the cover 31 and the board connector 1 is locked. A second locking claw 36 b, which is a horizontal ear, is formed in the inner wall element 34 b, typically the center thereof, and engages with the edge of the opening 13 provided in the housing 11. The second locking claw 36b, which is a horizontal ear, can set the lower limit of compression of the connector cover 31. In the example shown in the figure, the first lock claw 36 a is formed in the engagement convex portion 37, and the third lock claw 36 c is formed in the engagement concave portion 44. The first lock claw 36a, the second lock claw 36b, and the third lock claw 36c may be formed at any part, and the number thereof can be appropriately set as necessary. When the first lock claw 36a, the second lock claw 36b, and the third lock claw 36c are described in an integrated manner, the description will be made as the lock claw 36.

  Next, the board connector 1 and the mating connector 101 in the present embodiment will be described. 3A and 3B are exploded perspective views showing the board connector 1, the mating connector 101, and the connector cover 31 in the present embodiment. In the example shown in the figure, the board connector 1 is a so-called header connector, which is a standard product that conforms to the United States Mill Specification. The mating connector 101 is a so-called flat ribbon connector, and is a standard product that conforms to US mill standards, like the board connector 1.

  Here, the mating connector 101 is integrally formed of an insulating material such as a synthetic resin, and the mating housing 111 is formed of an insulating material and coupled to the mating housing 111, typically. A counterpart retainer 121 formed integrally with the counterpart housing 111 is provided. The mating connector 101 is connected to an end portion of a flat cable 191 also called a ribbon cable formed by connecting a plurality of conducting wires in parallel.

  The board connector 1 includes a housing 11 integrally formed of an insulating material such as a synthetic resin, and conductive terminals 61 attached so as to penetrate the bottom plate of the housing 11. The terminal 61 includes a tail portion 62 that extends downward from the bottom plate. The upper portion contacts the mating terminal 161 of the mating connector 101, and the tail portion 62 is connected to the substrate 91. It is attached to the bottom plate of the housing 11 by being fitted into the terminal insertion hole.

  A holding arm member 21 for holding the mating connector 101 is rotatably attached to each side of the housing 11. A holding claw 24 is formed at the free end of the holding arm member 21, and holding protrusions 124 formed on both sides of the upper surface of the counterpart housing 111 in a state where the counterpart connector 101 is fitted to the board connector 1. To be engaged. Thereby, the fitting state of the mating connector 101 and the board connector 1 can be reliably held, and unnecessary fitting release can be prevented.

  A convex portion 18 that engages with the engaging concave portion 44 of the connector cover 31 is formed on the side wall of the housing 11, and extends vertically in the vicinity of the lower end of the side wall of the housing 11. A concave groove 17 that engages with the ridge portion 42 of the cover 31 is formed. The protrusion 18 is formed with a lock hole 16 that engages with the third lock claw 36 c of the connector cover 31.

  Next, the connector cover 31 will be described with particular reference to FIGS. In the present embodiment, the board 91 shown in the figure is a circuit board used for gaming machines such as pachinko and pachislot machines, but is used for computers, vending machines, household appliances and the like. It may be a circuit board used for any kind of electric equipment or electronic equipment. Conductive traces and through holes 94 (not shown) are formed in the substrate 91. As is generally understood, the through hole 94 is used to penetrate the substrate 91 in the thickness direction and to be electrically connected to the conductive trace.

  The board connector 1 is mounted on the board 91 in such a direction that the bottom surface of the housing 11 faces the surface of the board 91 (upper side surface in FIG. 5). In this case, the tip of the tail portion 62 of the terminal 61 extending downward is inserted into the corresponding through hole 94. Thereby, the board connector 1 is attached to the board 91 in a predetermined direction. As shown in FIG. 5, the tip of the tail portion 62 of each terminal 61 passes through each through hole 94 and protrudes from the back surface (lower side surface in FIG. 5) of the substrate 91. The tail portion 62 is fixed to the through hole 94 and the substrate 91 by soldering or the like.

  The connector cover 31 is attached so as to surround the lower end of the substrate 91 of the substrate connector 1. In this case, the engaging convex portion 37, the closing projection 38, the engaging concave portion 44 and the convex strip portion 42 of the connector cover 31 are the concave portion 19, the opening 12 and the convex portion 18 formed in the housing 11 of the board connector 1. And engages with the groove 17. Therefore, the concave portion 19, the opening 12, the convex portion 18, and the concave groove 17 formed in the housing 11 of the board connector 1 are the engaging convex portion 37, the closing projection 38, the engaging concave portion 44 and the convex portion of the connector cover 31. Blocked by the ridge 42. Further, the inner wall element 34 b of the connector cover 31 has appropriate flexibility, is elastically deformed in accordance with the outer shape of the housing 11, and is in close contact with the outer peripheral surface of the housing 11. Further, when the lock claw 36 of the connector cover 31 engages with the lock hole 16 or the like of the housing 11, the positional relationship between the connector cover 31 and the board connector 1 is locked. Thereby, there is no gap between the periphery of the lower end of the board connector 1 and the connector cover 31, and the insertion of the probe from the outside of the device can be prevented appropriately. The lower ends of the outer wall element 34 a and the inner wall element 34 b of the connector cover 31 are in close contact with the surface of the substrate 91.

  The lid plate 92 is attached so as to cover the substrate 91 and so that the board connector 1 passes through the opening 93. The lid plate 92 is, for example, a thin plate made of an insulating resin such as acrylic, or a sheet made of an insulating resin such as polyimide. However, the lid plate 92 may be any thin plate or sheet-like plate member made of an insulating material. It may be of a kind. Note that the vertical and horizontal dimensions of the lid plate 92 may be any dimensions as long as they can surround the board connector 1, and may be any size. The outer peripheral portion of the opening 93 on the lower surface of the lid plate 92 abuts on the upper side wall 35 of the connector cover 31. In this case, when the upper side wall 35 is pressed downward toward the substrate 91 by the lid plate 92, the outer wall element 34a and the inner wall element 34b are elastically deformed to generate an upward spring force, The upper wall 35 is urged against the cover plate 92 by the spring force. Therefore, since the upper surface of the upper side wall 35 is in close contact with the lower surface of the cover plate 92, there is no gap between the cover plate 92 and the connector cover 31 around the opening 93. It can be prevented appropriately.

  The mating connector 101 is fitted with the board connector 1. The mating terminal 161 is connected to each conductor of the flat cable 191 at one end and is connected to the terminal 61 of the board connector 1 at the other end. Thereby, each conducting wire of the flat cable 191 is electrically connected to a corresponding conductive trace on the substrate 91. The holding arm member 21 is in a holding position for holding the mating connector 101, and the holding claws 24 are engaged with holding projections 124 formed on both sides of the upper surface of the mating housing 111. As a result, the mating state between the mating connector 101 and the board connector 1 is reliably maintained, and unintentional mating release is appropriately prevented.

  As described above, in the present embodiment, the main body portion 33 of the connector cover 31 includes the upper side wall 35 and the side wall 34 having a multiple structure. The upper side wall 35 abuts on the outer peripheral portion of the opening 93 on the side surface of the substrate 91 of the lid plate 92. The inner side wall element 34 b that is the innermost side wall of the multiple side walls 34 abuts on the outer peripheral surface between the cover plate 92 and the board 91 in the board connector 1. In this case, since the side wall 34 has a multiple structure and has appropriate flexibility, the inner side wall element 34 b can be elastically deformed corresponding to the outer shape of the board connector 1. Thereby, a gap does not occur between the inner wall element 34b of the connector cover 31 and the outer peripheral surface of the board connector 1, and an illegal act due to insertion of the probe can be appropriately prevented. Further, the side wall 34 is elastically deformed to generate an upward spring force, and the upper wall 35 is biased against the lid plate 92 by the spring force. As a result, there is no gap between the cover plate 92 and the connector cover 31 around the opening 93, and illegal acts caused by inserting the probe can be prevented appropriately. Further, since the side wall 34 is elastically deformed, the connector cover 31 can be easily attached and detached, and the connector cover 31 can be repeatedly mounted and removed.

  Further, in the side wall 34 of the double wall structure described in the present embodiment, the upper ends of the outer wall element 34 a and the inner wall element 34 b are connected to the upper side wall 35. Thereby, the outer wall element 34a and the inner wall element 34b are each in a state where they can be elastically deformed flexibly.

  Further, the space between the outer wall element 34a and the inner wall element 34b is hollow. Thereby, each member which comprises the cover 31 for connectors becomes thin. Therefore, the connector cover 31 can be easily molded with high accuracy. That is, the thickness of each member can be made uniform, and warpage or sink does not occur.

  Further, the inner wall element 34b includes a slit 41 that extends in the vertical direction and that has one end opened at the lower end of the inner wall element 34b. Thereby, as already demonstrated, it can adjust so that the softness | flexibility of the inner wall element 34b may become high.

  Furthermore, the main body 33 includes a connecting rib 39 that connects the outer wall element 34a and the inner wall element 34b. Thereby, the softness | flexibility of the outer side wall element 34a and / or the inner side wall element 34b can be adjusted suitably.

  Further, the main body 33 includes a closing protrusion 38 that closes the opening 12 of the housing 11 of the board connector 1. As a result, there is no gap between the board connector 1 and the connector cover 31, and illegal acts caused by inserting the probe can be prevented appropriately.

  FIG. 5 shows a portion where an illegal act will be performed. Only a part of the probes 171 to 173 is drawn, but is shown above the upper surface of the cover plate 92. The right side of FIG. 5 shows the connector cover 31 having a stepped shape so that the probe 171 is not easily inserted into the gap between the lid plate 92 and the board connector 1. Similarly, the left side shows a connector cover 31 for preventing the probe 172 from being easily inserted into the gap between the cover plate 92 and the board connector 1. Further, the left side of FIG. 5 shows the connector cover 31 that is lifted up to become a “reverse staircase” and passes upward through the opening of the cover plate 92. A stepped protrusion that rises through the opening of the lid plate 92 prevents the probe 173 from entering the device.
