Description

[Detailed Description of the Invention] [Summary] When a terminal section is provided at the upper part of the main body of a communication device, a connector assembly is housed in this terminal section, and the connector of an external line cable is connected to the connector assembly from the front side of the terminal section. Since there are inter-device cables and other items near the front of the terminal section, the connector assembly can be slid back and forth, and the connector assembly is moved forward only when connecting the external line cable, and after connection, the inside of the terminal section I tried to push it in.

[Industrial application field]

The present invention relates to a terminal panel for front access of a communication device;
In particular, there is a terminal section at the top of the device body that houses the communication device, and the internal cable extending from the back of the device body is connected to the connector assembly housed in the terminal section. This invention relates to the structure of a front access terminal panel for a communication device to which a cable connector can be connected.

[Conventional technology]

FIG. 6 shows the structure of a conventionally known front access terminal board for the above communication device. In this structure, a device main body 1 (1') that accommodates a communication device and a terminal section 5 (5') provided on the top constitute one system, and this system is normally installed in a vertical rack (not shown). ) can be stacked in multiple tiers. As shown in FIG. 6, the terminal section 5 has a receiving connector 152 fixed by a metal fitting 151, and an external line connector 9 (not shown) is connected to the receiving connector 152 from the front surface of the terminal section 5. Ru. A cable (not shown) of this external line connector is introduced into the terminal section 5 by a lateral force through a cable introduction port 153 provided at the front side of the terminal section 5. A connector 114 of an internal cable 113 extending from an upper connector 152 is connected to a receiving connector 112 attached to a backboard 111 on the back side of the apparatus main body 1 . In addition,
In FIG. 6, 115 is a cable holder, 116.1
17 is a front cover that is attached after connecting the connector, 119 is a screw for attaching the front cover, 120 is a back cover, and 121 is a metal fitting for attaching the device to a frame (not shown).

[Problem that the invention seeks to solve]

According to the conventional structure shown in FIG. 6, in order to connect the external line cable connector (not shown) to the receiving connector 152 fixed inside the terminal section 5, the operator has to go inside the terminal section 5. I had to put my hand in from the front,
A space (height Hl) is required for this purpose. Also,
Printed board circuit unit inside the device main body 1 (not shown)
If a direct cable connection is required between the PC board circuit unit (not shown) inside the other device body 1', the cable (not shown) should be passed through the top and bottom at the front of the terminal section 5. In this case, the receiving connector 152 for the external line described above must be mounted further inside the terminal portion 5. For this reason, the space (H3) of the terminal section 5 had to be further enlarged, which increased the height of the entire system (Hl), and also made it difficult to connect the external line cable connector. .

[Means for solving problems]

According to the present invention, there is a terminal section in the upper part of the device main body that houses the communication device, and the internal cable extending from the back side of the device main body is connected to the connector assembly housed in the terminal section. This is a front access terminal board for a communication device in which a connector for an external line cable can be connected from the front side of the terminal section, which provides an extra length for the cable inside the device, and connects the connector assembly to the terminal within the extra length. A terminal board for front access of a communication device is provided, which is characterized in that it is slidable in the front and rear directions within the terminal board.

[For production]

According to the present invention, the connector assembly can be connected while the connector assembly is pulled forward, and the connector assembly can be pushed into the terminal section after the connection work is completed, thereby reducing the size of the system.
It is possible to improve the workability of connector connection.

Embodiments of the present invention are shown in FIGS. 1 to 5. Similar to the conventional structure, the device body 1 (1') houses the communication device.
and the terminal part 5 (5') provided on the upper part.
Configure one system.

Inside the device main body 1, a plurality of printed circuit board circuit units 11 on which various components constituting a communication device are mounted are housed vertically between upper and lower covers 103° 10b having rail grooves so as to be freely insertable and removable. . There is a connector 12° 13 at the rear end of each circuit unit 11, and when the circuit unit 11 is inserted, it is connected to a connector (not shown) provided on the backboard 111 (FIG. 6) on the back of the device main body 1. be done. Also, on the circuit unit 11 there is a connector 14.1 for direct connection to the circuit units of the upper and lower apparatus main bodies.
5 are attached with their respective metal fittings.

A connector 17 of the coaxial cable 16 is connected to these connectors 14,15. Upper and lower covers 10 of the device main body 1
Cutouts 19a and 19b are formed in a and 10b for the coaxial cable 16 to pass through.

Corresponding notches or openings are also present on the upper and lower surfaces of the terminal portion 5. A unit mount 18 is attached to the front end of the circuit unit 11.

A connector 112 to which a connector 114 of an internal cable is connected is attached to a backboard (not shown in FIG. 1) on the rear side of the mounting body, similar to the conventional structure shown in FIG. The internal cable 20 extends from the back of the device main body 1 to the terminal section 5 at the top of the device main body 1, and is coupled to a connector 52 of a connector assembly 51 inside the terminal section 5.

As shown in FIGS. 2 and 3, the connector assembly 51 has a plurality of connectors 52 attached to a connector mounting plate 53 having a stepped front and rear step.

The internal cable 20 coupled to the connector 52 has an appropriate extra length (not shown) and has a horizontal frame 5 extending laterally.
