An interface connector 37 is provided on the back side of the package 33 on the back plate of the apparatus.

  Further, a stopper piece 43 is attached to the back side of the package 33 (the rear end side of the printed circuit board 31). The stopper piece 43 is attached to a peripheral portion of a notch 41 provided on a stopper plate 39 to be described later.

  As shown in FIGS. 1 and 2, the stopper piece 43 is formed in an L-shaped cross section, and its package mounting surface 43 a is fixed to the printed circuit board 31 with screws or rivets. Further, the package mounting surface 43a is provided with a bent piece 43b that is bent downward to be locked in the locking hole 45 provided in the printed circuit board 31, and the bent piece 43b is thus provided in the locking hole. 45, the stopper piece 43 is prevented from rotating after being attached to the printed circuit board 31. The stopper main body 43c of the stopper piece 43 formed in an L-shaped cross section is formed in a substantially U shape in a side view, and a key-shaped hooking claw 43d provided at the tip of the stopper main body 43c is a peripheral portion of the notch 41. It comes to hang on.

  In place of the locking structure of the bent piece 43b and the locking hole 45, as an example, the front and rear portions of the package mounting surface 43a are screwed or rivet fixed to the printed circuit board 31 to prevent the stopper piece 43 from rotating. You may plan.

  In FIG. 1, reference numeral 47 denotes a cable connector of an external cable 49 connected to the interface connector 37, and the back plate 35 is provided with an insertion hole 51 along the outer shape of the interface connector 37. The insertion hole The cable connector 47 can be connected to the interface connector 37 through which 51 is inserted.

  The surface of the back plate 35 is provided with screw holes (not shown) on the left and right sides of the insertion hole 47 obliquely above, and a cylindrical press-fit spacer 53 is formed at the periphery of both screw holes. It is attached with the same shaft.

  As shown in FIG. 2, the press-fit spacer 53 absorbs the projecting dimension of the interface connector 37 from the insertion hole 51 (back plate 35), and is used by making the thickness of the press-fit spacer 53 variable. The protrusion size of the interface connector 37 can be supported. 1 and 2, a stopper plate 39 is attached to the back plate 35 so as to be movable in the vertical direction via two screws 55 screwed into the screw holes.

  The stopper plate 39 is formed of a transparent resin material so that the connector connection name (not shown) displayed on the insertion port of the interface connector 37 of the back plate 35 can be visually recognized. As shown in FIG. On the left and right sides of the plate 39, elongated hole insertion holes 57 through which the screws 55 are inserted are provided in the vertical direction. A spacer tube 59 thicker than the thickness of the stopper plate 39 is attached to the screw 55. By using the spacer tube 59 in this way, the stopper plate 39 is not depressed even if the screw 55 is tightened. The stopper plate 39 can move in the vertical direction along the screw insertion hole 57.

  As shown in FIGS. 3 and 4, the screw insertion hole 57 is formed in a fan shape in which the hole is enlarged on the inside on the upper side.

  That is, as described above, the stopper plate 39 is structured to move in the vertical direction along the screw insertion hole 57, but the stopper plate 39 may be shifted to one side as shown in FIG. .

  Thus, in such a case, if the screw insertion hole 57-1 is formed into a linear long hole shape as shown in FIG. 5, when the stopper plate 39 is shifted to one side as shown in FIG. The screw 55 (spacer tube 59) hits the inner straight portion 57-2 of the screw insertion hole 57-1 and is caught, and the stopper plate 39 cannot be moved downward smoothly.

  Therefore, in the present embodiment, as shown in FIG. 4, even when the stopper plate 39 is shifted to one side and lowered, the screw insertion hole 57 has a fan shape that matches the inner peripheral diameter that rotates around the one screw 55. By making it a long hole, the screw 55 (spacer tube 59) is not hit and the stopper plate 39 can be smoothly moved downward.

  Further, as shown in FIGS. 1 and 2, the back plate 35 is provided with an insertion hole 61 through which the stopper main body 43 c of the stopper piece 43 is inserted. Then, a latching claw 43d at the tip of the stopper main body 43c inserted through the insertion hole 61 is latched on the peripheral edge of the notch 41 provided on the upper portion of the stopper plate 39.

  On the other hand, a notch 63 is provided at the lower portion of the stopper plate 39 so that the cable connector 47 does not abut against the stopper plate 39. The notch 41 and the notch 63 are provided so that the stopper plate 39 has a lateral S shape. Thus, a space-saving structure is provided in which the stopper plate 39 is accommodated within the height dimension of the package 33.

  When the cable connector 47 is connected to the interface connector 37 as shown in FIG. 7, the stopper plate 39 is placed on the upper surface of the cable connector 47 through the notch 63, and the stopper plate 39 is lifted. As shown in FIG. 8, the latching claw 43 d of the stopper body 43 c is latched on the peripheral edge of the notch 41 of the stopper plate 39.

  Therefore, even if it is attempted to remove the package 33 from the front surface of the communication device, the package 33 cannot be removed because the latching claw 43d is latched on the peripheral edge of the notch 41.

  Then, when the cable connector 47 is removed from the interface connector 37 as shown in FIG. 9, the stopper plate 39 moves downward along the screw insertion hole 57, and the peripheral portions of the latching claw 43d and the notch 41 as shown in FIG. The latching state is released.

  Therefore, in this state, the package 33 can be removed from the front surface of the communication device.

  When connecting the cable connector 47 to the interface connector 37, the stopper plate 39 may be lifted along the screw insertion hole 57. At this time, the stopper main body 43c of the stopper piece 43 contacts the peripheral edge of the insertion hole 61. Dimensions are designed not to touch.

  Since the stopper mechanism 65 according to the present embodiment is configured in this way, when the stopper plate 39 is attached to the back plate 35 with the screw 55, the stopper plate 65 is used even if the screw 55 is tightened by using the spacer tube 59. The stopper plate 39 can move in the vertical direction along the screw insertion hole 57 without pressing down 39.

  Further, by attaching the cylindrical press-fit spacer 53 to the peripheral edge portion of the screw hole of the back plate 35, the projecting dimension of the interface connector 37 from the back plate 35 is absorbed.

  When connecting the cable connector 47 of the external cable 49 to the interface connector 37 of the package 33 mounted on the communication device, the stopper plate 39 is lifted along the screw insertion hole 57, and then the interface connector as shown in FIG. 37, the cable connector 47 of the external cable 49 may be connected, and the stopper plate 39 is formed of a transparent resin material. Therefore, when the cable connector 47 is connected, it is displayed at the insertion port of the interface connector 37 of the back plate 35. The connection name of the connector is easily visible.

  Thus, when the cable connector 47 is connected to the interface connector 37 in this way, the cable connector 47 engages with the notch 63 and the stopper plate 39 rests on the upper surface of the cable connector 47 as shown in FIG. As shown in FIG. 8, the latching claw 43 d of the stopper main body 43 c is latched on the peripheral portion of the notch 41 of the stopper plate 39.

  Therefore, even if it is attempted to remove the package 33 from the front surface of the communication device, the package 33 cannot be removed because the latching claw 43d is latched on the peripheral edge of the notch 41.

  Further, even if the operator applies a strong force to remove the package 33 with a strong force, the bent piece 43b provided on the package mounting surface 43a is locked in the locking hole 45 of the printed circuit board 31 and attached. Since the stopper piece 43 is prevented from rotating, the stopper piece 43 does not rattle, and the latching claw 43 d is reliably latched on the peripheral edge of the notch 41.

  Then, when the cable connector 47 is removed from the interface connector 37 as shown in FIG. 9, the stopper plate 39 moves downward along the screw insertion hole 57, and the peripheral portions of the latching claw 43d and the notch 41 as shown in FIG. The hooking state is released.

  Therefore, in this state, the package 33 can be removed from the front surface of the communication device. 3 and 4, in the present embodiment, the screw insertion hole 57 is formed into a fan-shaped long hole having an inner peripheral diameter that rotates around one screw 55 as an axis. Since the smooth downward movement is possible, the stopper plate 39 moves downward without being caught on the way, and the latching state between the latching claw 43d and the peripheral portion of the notch 41 is surely released.

 (1) As described above, the stopper mechanism 65 according to the present embodiment starts from the front surface of the communication device apparatus unless the cable connector 47 connected to the rear surface side (the interface connector 37 on the rear surface side of the package 33) of the communication device device is removed. Since the package 33 cannot be removed, an operator who performs expansion or maintenance / replacement reliably removes the cable connector 47.

  Therefore, according to the present embodiment, it is possible to avoid a danger that may lead to a serious accident such as damage or disconnection of the external cable 49, damage to the interface connector 37, communication disconnection, or the like.

 (2) Further, in this embodiment, the stopper piece 43 is fixed to the package 33 so that the stopper piece 43 rotates and rattles even when an operator applies a strong force to pull out the package 33 with a strong force. As a result, there is an advantage that the stopper piece 43 is securely hooked to the peripheral edge of the notch 41.

 (3) Further, in this embodiment, the stopper plate 39 can be smoothly moved downward by making the screw insertion hole 57 into a fan-shaped long hole that matches the inner peripheral diameter that rotates around one screw 55. Therefore, the stopper plate 39 moves downward without being caught in the middle, and there is an advantage that the latching state between the latching claw 43d and the peripheral portion of the notch 41 can be reliably released.

 (4) Furthermore, in this embodiment, since the spacer tube 59 thicker than the thickness of the stopper plate 39 is attached to the screw 55 for attaching the stopper plate 39 to the back plate 35, the stopper plate 39 can be attached even if the screw 55 is tightened. The stopper plate 39 can move smoothly in the vertical direction along the screw insertion hole 57 without being pressed down.

 (5) Since the press-fit spacer 53 that absorbs the protruding size from the back plate 35 is attached to the peripheral portion of the screw hole of the back plate 35, the protruding size of the interface connector 37 to be used can be flexibly dealt with. .

 (6) In addition, in this embodiment, the stopper plate 39 is provided with a notch 63 in which the cable connector 47 engages and a notch 41 in which the stopper piece 43 is inserted and latched to form the stopper plate 39 in a lateral S shape. As a result, it is possible to save space in which the stopper plate 39 fits within the height dimension of the package 33.

 (7) In this embodiment, the stopper plate 39 is formed of a transparent resin material, and when the cable connector 47 is connected, the connection name of the connector displayed on the insertion port of the interface connector 37 of the back plate 35 is Since it was made visible easily, it became possible to prevent connector connection errors.

  In the above-described embodiment, the case where one interface connector 37 is attached to the back plate 35 as shown in FIG. 7 has been described. For example, two interface connectors 37 are attached in the lateral direction as shown in FIG. In some cases.

  Thus, in such a case, the notch 63 in FIG. 1 may be formed large in the lateral direction so that the two interface connectors can be engaged with the notch.

  Further, as described above, in the embodiment, the stopper plate 39 is formed of a transparent resin material so that the connection name of the connector displayed on the insertion port of the back plate 35 can be easily recognized. As in an embodiment of Item 9, the stopper plate may be formed of a steel plate, and the stopper plate may be provided with a notch for visually recognizing the display on the back plate.

  Thus, also in this embodiment, it is possible to prevent connector connection errors as in the above-described embodiment.
