Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, and specifically refers to a switching power supply for communication that is convenient for installation. Background Technique

[0002] A switched-mode power supply, also known as a switching power supply or a switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage level into the voltage or current required by the user through different forms of architectures. The input of a switching power supply is mostly an AC power supply (such as mains power) or a DC power supply, and the output is mostly devices that require a DC power supply, such as a personal computer. The switching power supply then converts the voltage and current between the two. Different from a linear power supply, the switching transistors used in a switching power supply mostly switch between the fully-on mode (saturation region) and the fully-off mode (cut-off region). Both of these modes have the characteristic of low dissipation. Although there is relatively high dissipation during the conversion between the two modes, the time is very short. Therefore, it is more energy-saving and generates less waste heat. Ideally, a switching power supply itself does not consume electrical energy. Voltage regulation is achieved by adjusting the on and off time of the transistor. On the contrary, during the process of generating the output voltage, the transistor in a linear power supply operates in the amplification region and consumes electrical energy itself. The high conversion efficiency of a switching power supply is one of its major advantages. Moreover, because the switching power supply operates at a high frequency, a small-sized and lightweight transformer can be used. Therefore, the switching power supply is also smaller in size and lighter in weight than a linear power supply. Switching power supply products are widely used in fields such as industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps, communication equipment, audio-visual products, security monitoring, LED light strips, computer cases, digital products, and instruments. In the military industry, military equipment is very common, and communication switching power supplies are included in military equipment.

[0003] The installation of the communication switching power supply in existing military equipment is generally fixed, and the installation and disassembly are relatively troublesome. Especially in a complex military environment, when it needs to be repaired or replaced, it takes a long time to remove it, which is rather inconvenient. Content of the Utility Model

[0004] To solve the above technical problems, the technical solution provided by the present utility model is: a communication switch power supply convenient for installation, including an installation backboard and a switch power supply assembly. The switch power supply assembly includes a switch power supply body and a connection housing. The switch power supply body is installed in the connection housing. A fixed connection plate integrally formed is provided at the rear side of the connection housing. A plurality of limit posts are provided around the bottom end of the fixed connection plate. Limit holes matching the limit posts are provided on the installation backboard. The bottom end of the fixed connection plate extends downward to form a pressing limit plate. A communicating threaded hole and a rectangular groove are provided inside the installation backboard. A fixing screw is installed in the threaded hole, and the inner end of the fixing screw abuts against the pressing limit plate extending from the bottom end of the fixed connection plate.

[0005] Further, the bottom end of the limit post is arranged in a frustum shape, with a narrow upper part and a wide lower part. The limit hole is arranged in a cat head shape. A bearing plate with the same shape is provided at the bottom end of the limit hole. The bottom end of the limit post extends into the limit hole from the center, and can be clamped and fixed at the cat ears of the limit hole, and the bottom end of the limit post is in contact with the bearing plate.

[0006] Further, a connection plate is provided on the side of the limit hole, and the bottom end of the connection plate is used to connect with the bearing plate.

Specific embodiments

[0018] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0019] The present utility model will be introduced in detail with reference to the accompanying drawings.

[0020] When the present utility model is specifically implemented, a communication switch power supply that is easy to install is provided, including a mounting backplane 1 and a switch power supply assembly. The switch power supply assembly includes a switch power supply body 2 and a connecting housing 3. The switch power supply body 2 is installed in the connecting housing 3. A fixed connecting plate 4 is integrally formed at the rear side of the connecting housing 3. A plurality of limiting posts 5 are arranged around the bottom end of the fixed connecting plate 4. Limiting holes 6 that cooperate with the limiting posts 5 are arranged on the mounting backplane 1. The bottom end of the fixed connecting plate 4 extends downward to form a pressing limiting plate 7. A communicating threaded hole 8 and a rectangular groove 19 are arranged inside the mounting backplane 1. A fixing screw 9 is installed in the threaded hole 8. The inner end of the fixing screw 9 abuts against the pressing limiting plate 7 extending from the bottom end of the fixed connecting plate 4. Embodiment

[0021] When the utility model is in use, a connection housing 3 is installed on the outside of the switching power supply body 2 to form a switching power supply assembly. Therefore, when installing the switching power supply body 2, the connection housing 3 can be directly installed and fixed on the installation backplane 1. During installation, multiple limit posts 5 on the rear fixing connection plate 4 of the connection housing 3 can be directly inserted into multiple limit holes 6 of the corresponding installation backplane 1. Since the limit holes 6 are arranged in the shape of a cat's head, when the limit posts 5 are inserted from the cat's head of the limit hole 6 and move to the corresponding cat's ears, the bottom ends of the multiple limit posts 5 abut against the bearing plate 10, and the limit posts 5 are clamped by the cat's ears of the limit hole 6. At the same time, the fixing screw 9 is inserted from the threaded hole 8 on the installation backplane 1, and the pressing limit plate 7 on the fixing connection plate 4 extends into the rectangular groove 19 on the installation backplane 1. Tighten the fixing screw inward to limit and fix the pressing limit plate 7 on the fixing connection plate 4. Only one fixing screw is required for installation and fixing during the fixing process of the above switching power supply, and the same is true for disassembly. When the above switching power supply assembly needs to be disassembled, only one fixing screw needs to be disassembled. After disassembling the fixing screw, pull the handle 16 with your hand to drive the fixing connection plate 4 to move left and right, so that the limit posts 5 on the fixing connection plate 4 move to the cat's head of the limit hole 6, and the limit posts 5 are released from the restraint of the limit hole 6. After the switching power supply assembly is installed, the installation backplane 1 can be fixed in the front or other positions by using multiple screws. Therefore, the above structure is convenient for disassembly and assembly, simple to operate, and saves the installation and disassembly time of the entire switching power supply during use.

[0022] Combined Figure 1 As can be seen, the threaded hole 8 on the installation backplane 1 is inside it. Therefore, the end of the fixing screw is hidden inside the installation backplane, and multiple limit posts 5 and multiple limit holes 6 on the installation backplane 1 are all in positions that are not visible to the eyes. For people who are not familiar with the structure of the entire device, it can play an anti-misassembly effect and ensure the safety of the switching power supply during use.

[0023] As a further elaboration of the utility model, the bottom end of the limit post 5 is arranged in a frustum shape with a narrow upper part and a wide lower part.

A plurality of heat dissipation holes 14 are provided on both the front and rear sides of the connecting housing 3. The structural settings of the above-mentioned heat dissipation holes and openings can increase the heat dissipation performance of the entire connecting housing during use.

[0026] As a further elaboration of the present utility model, a plurality of fixing holes 15 are provided on the mounting back plate 1 for installation and fixation by screws. The above-mentioned fixing holes facilitate the fixation and installation of the mounting back plate, and the operation is simple.

[0027] As a further elaboration of the present utility model, a handle 16 is fixedly connected above the fixed connecting plate 4.

[0028] As a further elaboration of the present utility model, a placement groove body 17 is formed by inward depression on the side surface of the mounting back plate 1, and a placement plate 18 is provided at the bottom end of the placement groove body 17 for the placement of installation tools, which provides convenience for the staff.
