Description

[Detailed Description of the Invention] The present invention relates to a crossbar switch (hereinafter simply referred to as a switch) for a telephone exchange, and particularly to a support structure for connecting an east line and delivering the switch alone.

Conventionally, when a switch is delivered as a single unit, if the switch is transported with the east line connected to it, the east line cannot be secured and a load is placed on the connection terminal, causing the wire to break.

Therefore, in the past, the switch and the east line were packaged separately and delivered as a single unit, and after the switch was mounted on the exchange rack already installed at the site, the east line was connected to the east line support plate prepared on the rack. The eastern line was fixed.

However, in this method, the connection terminals of the switch are soldered terminals, and the number of man-hours required for on-site construction becomes extremely large.

In addition, in terms of inventory management, the switch and the east line had to be managed separately, which required both manpower and management space.

The present invention aims to eliminate these drawbacks, and includes a bundled wire support hardware that is attached to the inner surface of the switch body, which is different from the east line support plate and the support plate attachment part, and is provided at the lower end of the attachment part. The feature is that the notch is aligned with the rising edge of the bottom of the switch.

This prevents the east line support plate from rotating, connects the east line when the switch is delivered separately, and fixes the east line to the east line support plate.
It will now be possible to transport the switch and the East Line in an integrated state.

Therefore, it is possible to reduce man-hours on site and in inventory management.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded view of one embodiment of the present invention, and FIG. 2 is an external view with the east line attached.

In the figure, 1 is the switch body, 2 is the east line support hardware, and 3
is the east line support plate, 4 is the support plate attachment part, 5 is the rising part formed at the bottom of switch 1, 6 is the round hole on the side of the switch, 7
is a mounting plate that fixes the east line support hardware 2 to the inner surface of the switch,
8 is a mounting screw, 9 is an east line, and 10 is a notch provided at both ends of the support plate mounting portion 4.

In the switch having such a structure, when attaching the east line support hardware 2 to the switch body 1, the east line support hardware 2 consisting of the east line support plate 3 and the support attachment part 4 is inserted into the inner surface of the switch body 1.

Next, fit the notch 10 provided at the lower end of the support mounting part 4 with the riser 5 on the bottom of the switch, fit the mounting plate 7 into the round hole 6 for transporting the switch that is open on the side of the switch body 1, and tighten the mounting screws 8. Fixed by

By using a switch with such a structure, even if the switch is transported with the east line connected, the load on the connection terminal is reduced, and there is a great effect against wire breakage, etc.
