SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems and proposes a telecommunication device capable of reliably guiding and storing a circuit package when the circuit package is stored.

[0008]

SUMMARY OF THE INVENTION That is, the present invention relates to a telecommunications device comprising a plurality of circuit packages in which a large number of electronic components are mounted on a substrate in parallel. In a telecommunication device comprising an opening for external insertion, and a guide rail extending inside the device in the insertion direction of the circuit package, which guides when the circuit package is stored,
An auxiliary guide means for the circuit package is provided between the opening and the end of the guide rail on the opening side.

The telecommunication device according to the present invention is used by providing auxiliary guide means for the circuit package between an opening for accommodating the circuit package and a guide rail for guiding the circuit package. Even if it is difficult for a user to visually recognize the guide rail when inserting the package into the device, the guide rail can be reliably inserted.

[0010] In a preferred embodiment of the telecommunication device according to the present invention, the auxiliary guide means may be a flat plate provided with a groove having a width through which a side edge of the circuit package can pass. Thereby, the auxiliary guide means can be realized with a simple configuration.

In a preferred embodiment of the telecommunication device according to the present invention, the auxiliary guide means may be a plate having a substantially V-shaped cross section. In this case, when the circuit package is inserted, the package is guided while being in contact with the plate material, so that the circuit package can be reliably guided to the guide rail inside the device.

In a preferred embodiment of the telecommunication device according to the present invention, the auxiliary guide means is moved in a direction in contact with and away from the board edge of the circuit package when the circuit package is inserted. It may be a movable auxiliary guide rail. In this case, when the circuit package comes into contact with the auxiliary guide rails, the upper auxiliary guide rail moves upward and the lower guide rail moves downward, that is, moves in a direction to escape from the circuit package, whereby the auxiliary guide rails move. The circuit package is smoothly guided. The auxiliary guide rail may include a rail main body for guiding the circuit package substrate, and a spring for vertically supporting the rail main body, and a rail main body for guiding the circuit package substrate. A rotating shaft for rotating and swinging the rail main body, a vertically movable guide pin for supporting the rail up and down, a guide fitting for guiding the guide pin so as to be movable up and down, and the guide inside the guide fitting. A configuration in which a coil spring disposed coaxially with the pin outer periphery may be provided.

Further, in a preferred embodiment of the present invention, the auxiliary guide means may be an elastic member which is deformed in contact with the circuit package when the circuit package is inserted. Two substantially arc-shaped leaf springs arranged side by side at a slightly wider interval than the thickness may be used. In this case, smooth guidance of the circuit package into the device can be realized with a simple configuration. Especially since the auxiliary guide means has elasticity,
Even when vertical displacement or rattling occurs during the insertion of the circuit package, this can be corrected and the circuit package can be guided inside the device.

[0014] The present invention also relates to a circuit package housed inside a telecommunication device.

That is, in the circuit package according to the present invention, a large number of electronic components are mounted on a substrate, and a connector for connecting to the telecommunication device is provided at one end of the substrate.
A front plate is provided at the other end opposite to this, and when housed in the telecommunication device, the end on the side where the connector is provided in the circuit package in which both sides of the board are guided by guide rails provided inside the device. The part is provided with an auxiliary guide member for guiding when the package is stored in the telecommunication device.

In the present circuit package, a member for assisting the guide when housed in a telecommunication device is provided in the package itself. Thereby, even when it is difficult for the user to visually recognize whether or not the package is correctly inserted into the device when storing the circuit package, it is possible to more reliably store the circuit package in the device. It can be realized with a simple configuration.

In a preferred embodiment of the circuit package according to the present invention, the auxiliary guide member is provided such that a height in a direction perpendicular to the substrate is equal to a height of the front plate in a direction perpendicular to the substrate. Alternatively, the length of the auxiliary guide member in the direction parallel to the width direction of the connector may be shorter than the width of the substrate. By doing so, it is possible to prevent the auxiliary guide member from interfering with other adjacent circuit packages, members inside the telecommunication device such as guide rails, and the like.

In a preferred embodiment of the circuit package according to the present invention, the auxiliary guide member may be formed in a substantially box shape having a tapered end portion. This makes it possible to realize the auxiliary guide member with a simple configuration.

Are provided respectively. In this drawing, electronic components and the like mounted on the substrate 51 are omitted.

The circuit package 50 is further provided with a box-shaped auxiliary guide 57 so as to cover the connector 52.
This auxiliary guide 57 is used to close the opening of the device when the circuit package 50 is housed in the telecommunication device, especially when the other side has already housed another circuit package or the package is not housed. When the panel is mounted, it is intended to reliably guide the circuit package into the device by avoiding interference with the circuit packages or panels on both sides.

As shown in FIG. 12A, the width of the auxiliary guide 57
Lg is smaller than the width Lb of the substrate 51 of the circuit package 50. This is to prevent the auxiliary guide 57 from interfering with the guide rail inside the device when inserting the circuit package 50 into the telecommunication device. Further, as shown in FIG. 12 (b), the height Hb of the auxiliary guide 57 in the direction perpendicular to the substrate 51 is equal to or slightly smaller than the height Hp of the front plate 53. . This makes it possible to prevent the circuit package 50 from interfering with another package already housed in the telecommunication device. The length Dg of the auxiliary guide 57 in the depth direction can be arbitrarily set as long as it does not interfere with an electronic component (not shown) mounted on the substrate 51, the connector 52, or the like.

The tip of the auxiliary guide 57 has a slightly tapered shape. This is for facilitating the guide inside the device when the circuit package 50 is stored. In other words, even if the tip of the auxiliary guide 57 hits another circuit package, the circuit package
57 is prevented from being blocked.

58 is attached, and on the right side already another circuit package 5
0 'is stored, and stored during that time.
Here, the back panel 58 has the same shape as the front plate 53 of the circuit package 50.

Next, as shown in FIG. 14B, when the circuit package 50 is to be inserted into the telecommunication device 60, the auxiliary guide 57 is moved by the left back panel 58 (or the right circuit package 50 '). ). However,
Since the tip of the auxiliary guide 57 is tapered, the movement of the circuit package 50 is not hindered, and can be inserted into the device 60 as shown in FIG. 14 (c). As described above, the height Hb of the auxiliary guide is equal to or slightly smaller than the height Hp of the front plate 53, so that the auxiliary guide smoothly passes between the left back panel 56 and the right package 50 '. it can.
