Technical Field

[0001] This utility model relates to the field of frequency converter technology, and more specifically, to a quick-connect variable frequency local oscillator module and its chassis. Background Technology

[0002] Frequency converters are generally used for signal frequency conversion. The internal structure of this type of platform chassis consists of the frequency converter, signal acquisition and processing module, and power supply module. The frequency converter needs to be fixed and encapsulated inside the chassis. Currently, the frequency converter is usually fixed inside the platform chassis by drilling holes with screws. This means that when debugging or replacing modules, it is necessary to open the chassis cover and remove the connecting cables and screws before replacement. Furthermore, because the steel cables are made of semi-steel material with high strength, the overall replacement process is quite cumbersome, resulting in a long replacement time.

[0003] Therefore, how to achieve rapid disassembly and assembly of frequency converters is a technical problem that urgently needs to be solved. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Example 1 This embodiment provides a quick-plug variable frequency local oscillator module. Figure 1 This is a schematic diagram of the overall structure of the quick-connect inverter local oscillator module. (See attached diagram) Figure 1 As shown, the quick-connect inverter local oscillator module includes a module body 1 and a mounting housing 2.

[0019] Among them, see Figure 2 As shown, the module body 1 has a push-pull strip 3 extending along a first direction on its side, and the mounting housing 2 has a guide groove 4 extending along the first direction on its inner side. The module body 1 slides in / out through the opening in the first direction of the mounting housing 2 when pushed or pulled by the sliding engagement between the push-pull strip 3 and the guide groove 4. In some embodiments, the side wall of the module body 1 in the first direction is also provided with a handle 15; the module body 1 has an upper cover plate 16 and a lower cover plate 17, and the push-pull strip 3 is disposed on the side of the upper cover plate 16 and the lower cover plate 17.

[0020] The module body 1 is slidably connected to the guide groove 4 inside the mounting housing 2 via the push-pull strip 3 on the side. The mounting housing 2 can be pushed in or pulled out directly in the first direction without tools. Compared with the traditional screw fixing method, it eliminates the tedious steps of disassembling the cover plate, unscrewing the screws and cables, which can greatly shorten the module replacement time.

[0021] Furthermore, the module body 1 is provided with a locking mechanism 5 on its side wall in the first direction. At least a portion of the locking mechanism 5 extends into the side wall of the mounting housing 2 for locking / releasing the module body 1. The locking mechanism 5 provided on the side wall of the module body 1 can be easily toggled to lock or release the module from the mounting housing 2.

[0022] In some embodiments, the upper cover plate 16 and / or the lower cover plate 17 have through holes 18 on their side walls in the first direction. The locking mechanism 5 is a lever with its first end hinged and its second end extending outside the through hole 18. The outer side of the lever is provided with a buckle, and the side wall of the mounting housing 2 is provided with a groove that matches the buckle.

[0023] Further, see Figure 3 As shown, the mounting housing 2 has an interface mounting plate 6 at its opening in the second direction, and the module body 1 has a positioning hole 21 on its side wall in the second direction. The interface mounting plate 6 has a guide pin 7 that matches the positioning hole 21. The second direction is the opposite of the first direction. The guide pin 7 on the interface mounting plate 6 in the second direction of the mounting housing 2, through its cooperation with the positioning hole 21 on the side wall of the module body 1, can automatically guide and align the module during insertion, avoiding interface damage caused by manual alignment deviation. At the same time, the cooperation between the guide pin 7 and the positioning hole 21 can withstand a certain lateral force, enhancing the stability of the module after installation.

[0024] Furthermore, the mounting housing 2 has a first bending portion 8 on both sides, and a first screw hole 9 is provided on the first bending portion 8. The lower end of the interface mounting plate 6 has a second bending portion 10, and a second screw hole 11 is provided on the second bending portion 10.

[0025] Furthermore, the second sidewall of the module body 1 is also provided with a power supply plug 22, and the interface mounting plate 6 is provided with a power supply socket 12 adapted to the power supply plug 22; the second sidewall of the module body 1 is also provided with a first radio frequency coaxial connector 20, and the interface mounting plate 6 is provided with a second radio frequency coaxial connector 13 adapted to the first radio frequency coaxial connector 20; the power supply plug 22 of the module body 1 and the power supply socket 12 of the interface mounting plate 6, as well as the first radio frequency coaxial connector 20 and the second radio frequency coaxial connector 13, are all designed to be compatible. When the module is fully pushed into the mounting housing 2, the plug and socket are electrically connected simultaneously, eliminating the need for manual plugging and unplugging of cables, reducing the risk of poor contact, and further improving installation efficiency.

[0026] The module body 1 has several millimeter-wave connectors 14 on its side wall in the first direction. The millimeter-wave connectors 14 on the side wall in the first direction of the module body 1 can be directly exposed to the outside of the chassis, which facilitates quick connection with external devices and meets the requirements of high-frequency signal transmission.

A slot is provided on the side of the chassis body near the mounting section, and the size of the slot is not smaller than the opening size of the mounting housing 2 in the first direction. The slot size in the chassis body is not smaller than the opening size of the mounting housing 2 in the first direction, allowing the module body 1, along with the mounting housing 2, to be directly pushed in or removed from the side of the chassis without disassembling the chassis cover. This is particularly suitable for compact chassis or multi-module side-by-side installation scenarios, saving space while improving maintenance convenience.

[0029] Furthermore, the side wall of the chassis body is provided with a third screw hole 19 corresponding to the first screw hole 9, and the inner bottom of the chassis body is provided with a fourth screw hole corresponding to the second screw hole 11.
