Utility model content
For the problem of above existence, the utility model has offered a kind of transmitter with power amplifier unit navigation system, can effectively improve the accuracy of power amplifier unit insertion cabinet pit, can prevent the damage to power amplifier unit in the situation that of blindmate mistake simultaneously.
To achieve these goals, the technical solution adopted in the utility model is:
With a transmitter for power amplifier unit navigation system, comprise transmitter cabinet, power amplifier unit, also comprise guided way, dowel device and float positioning device simultaneously; Wherein said guided way and described case backboard face are not placed in same plane, and this guided way one end is connected with described case backboard is vertical, and cooperatively interact with the base plate of power amplifier unit; Described dowel device comprises the alignment pin jack being positioned on case backboard and is positioned at the alignment pin that power amplifier unit is mutual corresponding with described alignment pin jack position; Described float positioning device comprises the unsteady positioning socket being positioned on case backboard and is positioned at the latch on power amplifier unit, and the two position is mutually corresponding; Wherein, the cooperation stroke of guided way, dowel device, float positioning device from long to short sequentially.
Preferably, described guided way is positioned at the bottom position of described case backboard, and when power amplifier unit is installed, power amplifier unit base plate is along described guided way, preliminary near slot after cabinet.
Preferably, an above-described power amplifier unit navigation system comprises two described dowel devices, lays respectively at the two ends up and down of case backboard and power amplifier unit correspondence position, can play like this balance effect of location exactly again.
Preferably, the length of the above alignment pin is more than or equal to the degree of depth of described alignment pin jack, can the in the situation that of blindmate mistake, protect power amplifier unit not damaged.
Preferably, described float positioning device comprises floating guiding positioning socket and the rough unsteady socket that floats and correct for accurately correcting location, and both are all positioned on described case backboard.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1,, in the utility model, first, the guided way of rack subrack first carries out preliminary rough travel guidance to power amplifier unit; Secondly, during on the way near case backboard, then by the cooperation of dowel device, accurately locate, last, connector place endways, by the cooperating of float positioning device, makes up the position error causing because of a variety of causes.Power amplifier unit, by behind the location of this three steps guide-localization system, just can inject like clockwork in the slot on rear plate, thereby it is hot-swappable to realize power amplifier unit, reaches the object that is convenient for changing, keeps in repair transmitter apparatus.
2, the alignment pin setting in the utility model, not only can play the accurately effect of location of power amplifier unit, simultaneously can also be the in the situation that of blindmate mistake, while preventing from plugging power amplifier unit, make power amplifier unit not in correct guided way because of carelessness, damage power amplifier unit equipment with case backboard collision.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model is a kind of transmitter with power amplifier unit navigation system, and as shown in Figure 4, the navigation system in the transmitter that the utility model provides, can inject the slot (not shown) being arranged on case backboard 7 exactly by power amplifier unit 6.Power amplifier unit navigation system described in the utility model, comprise three devices, and when work has engagement process each other, these three devices are respectively and first carry out the guided way 1 of cooperating, carry out the dowel device for accurate location of second step cooperating and complete the float positioning device of last cooperating again.As shown in Figure 1, guided way 1 is not placed with case backboard 7 planes in same plane, and one end of guided way 1 is connected with case backboard 7 is vertical, and guided way 1 is positioned at the bottom position of case backboard 7, when installing or changing power amplifier unit 6, can allow described power amplifier unit 7 advance along described guided way 1, can play the effect of preliminary rough guiding.
