Description

Technical Field

[0001] This utility model relates to DC regulated power supply technology, specifically to a DC regulated power supply. Background Technology

[0002] A DC regulated power supply is a device that can convert unstable AC power (such as 220V AC mains power) or other DC power sources into DC power with stable output voltage and adjustable current. Its core function is to eliminate the influence of input voltage fluctuations, load changes and other factors on the output, and ensure that the output DC voltage / current is maintained at the set value, so as to provide stable power support for electronic equipment.

[0003] DC regulated power supplies are commonly used in electronic experiments and research and development, equipment production and debugging, battery charging and maintenance, and other scenarios. In these applications, DC regulated power supplies are usually used in conjunction with alligator clips. One end of the alligator clip is connected to the terminal of the DC regulated power supply, and the two alligator clips are connected to the positive and negative terminals of the DC regulated power supply, respectively. DC power is output through the alligator clips during use. In the prior art, unused alligator clips are usually placed directly on the workbench.

[0004] In practical use, continuous operation is usually required (taking sensor testing as an example, the sensor's terminals are directly exposed to the air). During operation, different sensors need to be tested. When changing sensors, the alligator clips are separated from the sensors. At this time, the alligator clips are placed directly on the surface of the workbench. This method has the following two major safety hazards:

[0005] Risk of electric shock: The metal parts of the alligator clips are exposed, and operators may accidentally touch them and suffer electric shock.

[0006] Short circuit risk: The positive and negative alligator clips are easily contacted if placed haphazardly, which can cause a short circuit, damage equipment, or even cause a fire.

[0007] Therefore, a DC regulated power supply is proposed to solve the problems mentioned above. Utility Model Content

[0008] Based on the above description, this utility model provides a DC regulated power supply to solve the problem of unsafe placement of alligator clips when using traditional DC regulated power supplies.

[0009] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A DC regulated power supply, comprising: a power supply body, a fixing frame, and a partition block;

[0010] The mounting bracket is disposed on the upper surface of the power supply body, and a partition block is snapped into it to divide the mounting bracket.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the fixing frame includes a hollow frame, which includes two upright plates disposed on the upper surface of the power supply body, and a transverse top plate is disposed between the two upright plates.

[0013] Furthermore, both the upper and lower surfaces of the transverse top plate are provided with locking grooves.

[0014] Furthermore, the separator includes an insulating separator made of insulating material and includes a separator body, which is an N-shaped frame.

[0015] Furthermore, an insulating horizontal plate is provided between the two inner side walls of the partition body. The insulating horizontal plate divides the space inside the partition body into an upper compartment and a lower compartment from top to bottom. The lower compartment is open on the side opposite to the insulating horizontal plate.

[0016] Furthermore, a card interface is provided on one side of the insulating horizontal plate, and the horizontal top plate is inserted into the card interface.

[0017] Furthermore, two snap-fit ​​plates are provided on the side of the insulating horizontal plate facing the card interface. The two snap-fit ​​plates are made of rigid insulating elastic material, and the upper and lower snap-fit ​​plates are symmetrically distributed, with the distance between them being consistent with the height of the card interface.

[0018] Furthermore, each of the upper and lower snap-fit ​​plates has snap-fit ​​protrusions on opposite sides. The snap-fit ​​protrusions are hemispherical and extend into the interior of the snap-fit ​​groove.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0020] 1. This utility model, by setting up a power supply body, a hollow frame and insulating separators, etc., through the cooperation between the insulating separators and the hollow frame, allows the alligator clips to be directly clamped to the outside of the insulating horizontal plate, and the insulating separators separate multiple alligator clips, thereby preventing electric shock or short circuit when the alligator clips are placed on the workbench.

[0021] 2. By designing the insulating separator, it is easy to install inside the hollow frame. Through the cooperation between the snap-fit ​​plate and the snap-fit ​​protrusion, the snap-fit ​​plate undergoes elastic deformation during the process of the horizontal plate being snapped into the snap-fit ​​interface. As the horizontal plate is snapped into the interface, the snap-fit ​​plate returns to its original shape. At this time, the snap-fit ​​protrusion is snapped into the slot, thus achieving the effect of easy disassembly and installation of the insulating separator. Attached Figure Description

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0036] Please see Figures 1-7 A DC regulated power supply includes: a power supply body (1), a mounting frame, and a partition block;

[0037] The fixing frame is disposed on the upper surface of the power supply body (1), and a partition block is snapped in the inside, the partition block being used to divide the fixing frame;

[0038] The fixing frame includes a hollow frame (2), preferably made of TPE material. The hollow frame (2) includes two upright plates (22) set on the upper surface of the power supply body (1). A horizontal top plate (21) is set between the two upright plates (22). The upper and lower surfaces of the horizontal top plate (21) are provided with slots (23).

[0039] Based on the above, the power supply body 1 is a traditional DC regulated power supply. Its internal structure and specific working principle will not be described in detail here. The setting of the horizontal top plate 21 and the slot 23 allows the insulating separator 3 to be interlocked with the hollow frame 2.

[0040] like Figures 4-6 , Figure 8 as well as Figure 9 As shown, the partition block includes an insulating partition (3), which is made of insulating material, preferably TPE material, and includes a partition body (31). The partition body (31) is an n-shaped frame. An insulating horizontal plate (32) is provided between the two inner side walls of the partition body (31). The insulating horizontal plate (32) divides the space inside the partition body (31) from top to bottom into an upper compartment (34) and a lower compartment (33). The lower compartment (33) is open on the side away from the insulating horizontal plate (32).

[0041] A card slot (35) is provided on one side of the insulating horizontal plate (32). The horizontal top plate (21) is inserted into the inside of the card slot (35). Two card plates (36) are provided on the side of the insulating horizontal plate (32) facing the card slot (35). The two card plates (36) are made of rigid insulating elastic material, preferably TPE material. The upper and lower card plates (36) are symmetrically distributed, and the distance between them is consistent with the height of the card slot (35).

[0042] Each of the two snap-fit ​​plates (36) is provided with a snap-fit ​​protrusion (37) on one side of the upper and lower plates. The snap-fit ​​protrusion (37) is a hemispherical protrusion and extends into the interior of the snap-fit ​​groove (23).

[0043] Based on the above, the insulating partition 3 serves to separate the hollow frame 2. By interlocking the insulating partition 3 with the transverse top plate 21, the transverse top plate 21 is inserted into the inside of the interlocking interface 35. During this process, the transverse top plate 21 presses against the upper and lower interlocking protrusions 37, and causes the two interlocking plates 36 to undergo elastic deformation. When the interlocking protrusions 37 move to the position of the interlocking groove 23, the interlocking plates 36 return to their original shape, thereby allowing the interlocking protrusions 37 to be inserted into the inside of the interlocking groove 23, thus achieving the effect of interlocking the insulating partition 3 with the transverse top plate 21.

[0044] Furthermore, the insulating separator 3 can separate multiple alligator clips. The insulating horizontal plate 32 allows the alligator clips to be held on the outside of the insulating horizontal plate 32, which facilitates subsequent use and prevents the human body from directly contacting the alligator clips.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
