Description

Technical Field

[0001] The utility model relates to the technical field of signal amplifiers, in particular to an external measurement signal amplifier for a telemetry system. Background Art

[0002] A telemetry system is a system that has the function of measuring, transmitting and processing certain parameters of an object at a certain distance. Its function is to transmit the object parameter values ​​measured at a short distance to a distant measuring station, so as to realize long-distance measurement. The working process of the telemetry system is divided into two parts: the transmitting end on the spacecraft and the receiving end on the ground. At the transmitting end, the sensor first converts the parameter signal into a weak current signal, which is then amplified by an external signal amplifier into a standardized voltage signal suitable for collection. Then, a multi-channel signal modulator combines multiple standardized signals according to a certain system to form a group signal suitable for transmission on a single channel to modulate the carrier of the transmitter. Finally, the modulated signal is amplified by the transmitter power and sent to the transmitting antenna to be transmitted into space.

[0003] At present, the shells of the external signal amplifiers on the market are mostly made of aluminum alloy or other metals (high structural strength and good heat dissipation effect), and then heat dissipation fins are set on the surface of the shell to facilitate heat dissipation with the external air (as shown in the attached manual). Figure 4 However, the housing of the existing external measurement signal amplifier is mostly fixed by screws, which makes it inconvenient to disassemble when the internal circuit board of the external measurement signal amplifier fails and needs to be repaired or replaced. Utility Model Content

[0007] As a further solution of the utility model: fixing plates are arranged at the four corners of the bottom of the shell, and fixing holes are opened on the fixing plates.

[0008] As a further solution of the present utility model: The upper heat dissipation fins are arranged in one-to-one correspondence with the front heat dissipation fins and the rear heat dissipation fins.

[0010] As a further solution of the present utility model: A signal input port and a signal output port are respectively arranged on both side surfaces of the housing.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing a housing, a housing cover and a quick clamping component, the housing cover and the housing can be quickly connected and disassembled through the quick clamping component, which is convenient for personnel to repair and replace the circuit board of the external signal amplifier.

[0013] 2. By providing upper heat dissipation fins, front heat dissipation fins, rear heat dissipation fins and a heat dissipation fan, when the housing cover is fixedly installed on the housing, the front and rear ends of the upper heat dissipation fins are respectively butted against the front heat dissipation fins and the rear heat dissipation fins one by one, so that the heat dissipation fins can be connected into a whole, which is convenient for heat conduction. At this time, the heat dissipation fan can accelerate the air flow around the heat dissipation fins, so that the heat on the heat dissipation fins can be quickly transferred to the surrounding air, thereby accelerating the heat dissipation speed of the outer amplifier housing and being beneficial to the stable operation of the external signal amplifier.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 3 , in the embodiment of the present invention, an external measurement signal amplifier for a telemetry system includes a housing 1 and a housing cover 2. A circuit board is arranged inside the housing 1, and the housing cover 2 is arranged on the upper part of the housing 1. Slots 3 adapted to the housing 1 are provided at the bottom ends of both side surfaces of the housing cover 2. Quick snap-fit components 4 are installed on both sides of the housing 1 and the housing cover 2. The quick snap-fit component 4 includes an elastic chuck 401 and a buckle 402. The elastic chuck 401 is in plug-in fit with the buckle 402. When it is necessary to repair or replace the circuit board inside the external measurement signal amplifier, just press the elastic chucks 401 inside the buckles 402 on both sides of the external signal amplifier at the same time, so that the protruding parts of the elastic chucks 401 enter the buckles 402, and then the housing cover 2 can be directly removed from the housing 1. After the repair or replacement is completed, directly cover the housing cover 2 on the housing 1 and press it so that the elastic chuck 401 snaps into the buckle 402. Signal input ports 10 and signal output ports 11 are respectively arranged on both side surfaces of the housing 1. The signal input ports 10 and the signal output ports 11 are structures standardly equipped in existing signal amplifiers and will not be elaborated here.

[0021] Please refer to Figures 1 - 2, upper heat dissipation fins 5 are provided on the shell cover 2, front heat dissipation fins 6 and rear heat dissipation fins 7 are respectively installed on the front and rear end faces of the shell 1, a heat dissipation fan 8 is installed on the front heat dissipation fins 6, and the heat dissipation fan 8 is connected to the power supply circuit on the circuit board through a wire. A wire passing hole is provided on the shell 1 to facilitate the wire of the heat dissipation fan 8 to pass through. The upper heat dissipation fins 5 are arranged in one-to-one correspondence with the front heat dissipation fins 6 and the rear heat dissipation fins 7. Such a design enables the upper heat dissipation fins 5 to be connected to the front heat dissipation fins 6 and the rear heat dissipation fins 7 after the shell cover 2 and the shell 1 are installed and fixed, facilitating heat conduction. The front heat dissipation fins 6 are cross-distributed, which can facilitate the transfer of heat to the position directly opposite the heat dissipation fan 8 through the front heat dissipation fins 6. During operation, the external signal amplifier continuously generates heat, which is transferred to the heat dissipation fins through the shell 1 and the shell cover 2, and then heat exchange is carried out with the external air through the heat dissipation fins. At the same time, when the heat dissipation fan 8 is turned on, the air flow around the front heat dissipation fins 6 is accelerated, making the heat exchange rate between the front heat dissipation fins 6 and the external air faster than that of the upper heat dissipation fins 5 and the rear heat dissipation fins 7. In this way, the heat on the rear heat dissipation fins 7 and the upper heat dissipation fins 5 will transfer to the front heat dissipation fins 6 and be carried away by the rapidly flowing air. In this way, the rate of heat exchange between the overall heat dissipation fins and the external air can be accelerated, improving the heat dissipation effect.

[0022] Please refer to Figure 2 , fixing plates 9 are provided at the four corner positions of the bottom of the shell 1, fixing holes are provided on the fixing plates 9, and the setting of the fixing plates 9 can facilitate the installation of the external signal amplifier on the corresponding equipment or platform for use.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
