Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a connection connector portion of a television broadcasting apparatus using water cooling.
[0002]
[Prior art]
As shown in FIG. 1, a television broadcaster is configured by mounting a plurality of PA units 2 on a transmitter 1.
[0003]
As shown in FIG. 2, the PA is fitted by sliding the guide 3 provided on the side surface of the PA 2 on the receiving rail 4 held by the transmitter housing. In addition, two guide pins 5 are provided for the water-cooled connectors 6 and 7, and the connector pins are positioned by inserting the guide pins 5 into the guide holes 9 of the PA bracket 8.
[0004]
[Problems to be solved by the invention]
The purpose is to realize the following (1) and (2).
[0005]
(1) An error in the mounting dimensions of the PA guide 3 and the receiving rail 4 is absorbed by one guide pin for one connection connector, and the component cost of the connector fitting portion is reduced.
[0006]
(2) Even if the PA is inclined when the PA connector and the transmitter connector are fitted, the connector is fitted in parallel.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the following structures (1) and (2) are adopted.
[0008]
(1) The connector mounting plate is fixed in a floating structure.
(2) A ball plunger is mounted between the PA receiving plate and the connector mounting plate, and the inclination angle is absorbed by utilizing the expansion and contraction of the plunger.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention is shown in FIG. When the PA 2 is inserted into the transmitter, the guide 3 on the side of the PA is held by the receiving rail 4 and can be positioned in the vertical direction. In the horizontal direction, the guide pins 5 are used for positioning.
[0010]
When fitting the connector 6 of the PA 2 and the transmitter side connector 7, as shown in FIG. 4, the collar 11 is inserted into the connector fixing plate 10 to absorb horizontal and vertical errors and fixed with screws 12. By floating due to the dimensional difference between the processed hole of the connector fixing bracket 10 and the collar 11, an error in the position of the PA and the PA backing plate is absorbed.
[0011]
The ball plunger 14 is fixed to the PA receiving plate 8 and is held in the V groove 15 of the connector fixing bracket 10 and positioned in the vertical direction. Further, the horizontal direction is determined by using one guide pin 5 with respect to the connector.
[0012]
【The invention's effect】
According to the present invention, even when the PA is inclined when the PA unit connector and the transmitter connector are fitted, the connectors can be fitted in parallel.
