Description
Technical field
The present invention relates to technical field of communication equipment, specially a kind of digital SPC exchange for communication equipment.
Background technique
The basic function of digital SPC exchange are as follows: the access of user's line, trunk connection, charging, equipment management etc..It is local to hand over
Change planes the off-hook movement of automatic detection user, to the telephone set loopback dialing tone of user, receive pulse signal that phone generates or
Dual-tone multifrequency (DTMF) signal, (called number may be in the same interchanger for the connecting for then completing from caller to called number
It may also be in different interchangers).After the completion of connecting, interchanger will keep connecting, side's on-hook until detecting communication.
PCA plate in the pedestal of present communication equipment, especially digital SPC exchange mostly will when installation
Then connecting pin grafting in the bottom and pedestal of PCA stretches out the Serial Interface Component on PCA plate from the limiting slot of chassis side,
Serial Interface Component is finally mounted on to the side wall of pedestal using screw or other fasteners, such mounting structure needs additional peace
Holding tool assembly and disassembly is inconvenient.
Summary of the invention
In order to overcome the shortcomings of that prior art, the present invention provide a kind of digital SPC for communication equipment
Machine can effectively solve the problem of background technique proposes.
The technical solution adopted by the present invention to solve the technical problems is: a kind of digital SPC for communication equipment
Machine, including pedestal and PCA plate, the PCA plate include grafting port and PCA substrate, and the pedestal includes side plate and mounting plate, institute
It states side plate and is provided with several heat release holes, the base end is equipped with port protection piece, and position is opened among the port protection piece
There is limiting slot, the grafting port is exposed outside across the limiting slot, and the PCA substrate is fixed by screw in the installation
On plate, upper cover is installed above the pedestal, the upper tops are provided with ventilation hole.
Preferably, the side plate top is provided with buckle, and the port protection piece is stuck on the buckle.
In any of the above-described scheme preferably, the PCA substrate is by four fastened by screw on the mounting plate.
In any of the above-described scheme preferably, the grafting port is exposed on the outside of the limiting slot, convenient for plug.
In any of the above-described scheme preferably, the upper cover and the pedestal are extrusion fit.
In any of the above-described scheme preferably, the pedestal, the port protection piece and the upper cover are sheet metal
Material.
Compared with prior art, the beneficial effects of the present invention are:
The present invention provides communication equipment PCA board mounting structure and digital SPC exchange, grafting port and limiting slot
Clamping limit cooperation is constituted, when disassembly, the port protection piece being detachably connected need to only be removed, so that it may easily change PCA
Plate changes easy to maintain and mounting structure and consolidates, and stable structure is not in fall off in transport.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The explanation of following embodiment be with reference to attached drawing, can be to the specific embodiment implemented to the example present invention.
The direction and position term that the present invention is previously mentioned, for example, "upper", " in ", "lower", "front", "rear", "left", "right", "inner", "
Outside ", " side " etc. is only direction and position with reference to annexed drawings.Therefore, the direction and position term used is to illustrate
And understand the present invention, rather than to limit the present invention.
Embodiment:
As shown in Figure 1, the present invention provides a kind of digital SPC exchange for communication equipment, including pedestal 1 and PCA
Plate 2, the PCA plate 2 include grafting port 3 and PCA substrate 4, and the pedestal 1 includes side plate 5 and mounting plate 6, and the side plate 5 is opened
There are several heat release holes 7,1 end of pedestal is equipped with port protection piece 8, and the intermediate position of the port protection piece 8 is provided with limit
Position slot 9, the grafting port 3 is exposed outside across the limiting slot 9, and the PCA substrate 4 is fastened on the peace by screw 10
In loading board 6, upper cover 11 is installed above the pedestal 1, is provided with ventilation hole 12 at the top of the upper cover 11.
5 top of side plate is provided with buckle 13, and the port protection piece 8 is stuck on the buckle 13.
The PCA substrate 4 is fastened on the mounting plate 6 by four screws 10.
The grafting port 3 is exposed in 9 outside of limiting slot, convenient for plug.
The upper cover 11 is extrusion fit with pedestal 1.
The pedestal 1, the port protection piece 8 and the upper cover 11 are sheet metal material.
