[0002] A junction box is a device used for electrical connections. It is mainly used to protect the connection points of wires and cables from the influence of the external environment (such as dust, moisture, corrosive gases, etc.). It is widely used in industries, construction, coal mines, outdoor equipment and other fields, and is an indispensable part of electrical systems.

[0003] Currently, existing junction boxes are not suitable for accommodating cables of different specifications. When the cable diameter is smaller than the junction box's aperture, gaps will be left, making the junction box's terminals susceptible to the infiltration of external dust, rainwater, and other contaminants.

[0004] Therefore, this application provides a high-sealing junction box to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-sealing junction box to solve the problem that existing junction boxes are not easy to adapt to cables of different specifications, resulting in gaps when the cable diameter is smaller than the junction box aperture, making the junction box terminals susceptible to the infiltration of external dust, rainwater and other factors.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A high-sealing junction box includes a base plate, on which two vertical sidewalls are symmetrically fixed on both sides of the front side of the base plate, and a C-shaped frame is horizontally slidably installed between the two sidewalls to form a box structure.

[0008] The upper and lower ends of the C-shaped frame are each fitted with a ring-shaped perforation. Several arc-shaped blades are movably installed in the center of the perforation. A limiting bracket for retracting the arc-shaped blades is rotatably installed in the center of the perforation to form a camera aperture structure. A sealing sleeve for fitting onto a cable is fitted at the opening of the perforation. The arc-shaped blades retract and abut against the outer edge of the sealing sleeve to form a seal.

[0009] Optionally, wiring holes are provided in the middle of the upper and lower end faces of the C-shaped frame, and the hole ring is installed on the outside of the port of the wiring hole.

[0010] Optionally, the top and bottom outer sides of the C-shaped frame are provided with sliding grooves, and horizontal sliding edges are fixed on one side of the two facing sidewalls corresponding to the position of the sliding grooves, and the sliding edges slide horizontally with the sliding grooves.

[0011] Optionally, a wiring terminal is installed in the middle of the C-shaped frame.

[0012] Optionally, a sealing door is hinged to one edge of one of the two sidewalls. The sealing door covers the opening of the C-shaped frame and, together with the two sidewalls, forms a seal for the terminal block.

[0013] Optionally, the arc-shaped blade is an arc-shaped structure, one end of the arc-shaped blade is movably connected to the inner hole ring, and the other end of the arc-shaped blade is slidably engaged with the limiting frame.

[0014] Optionally, the outer edge of the limiting frame is fixed with a lever extending out of the annular ring, and the outer side of the annular ring is provided with an arc-shaped through groove for the lever to slide horizontally.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the cooperation of the substrate, side walls, and C-shaped frame, the C-shaped frame can be easily pulled out, so that when the operator is doing wiring, the C-shaped frame can be pulled out from between the two side walls, increasing the working space. Compared with the existing technology that requires wiring operations to be performed in a narrow box, this device has a wider operating space and is more convenient to use.

[0017] In the above solution, thanks to the design of the perforated ring, the size of the hole inside the ring can be easily adjusted according to the diameter of the cable being wired. Combined with the sealing sleeve, a seal is formed, enabling the device to be adapted to different specifications of cables for sealed installation.

[0018] In summary, this device is flexible and convenient to use, can be adapted to the sealed installation of cables of different specifications, and has a good overall performance. Attached Figure Description

[0028] The high-sealing junction box provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0030] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0031] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0032] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a high-sealing junction box, including a base plate 1. Two vertical sidewalls 2 are symmetrically fixed on both sides of the front of the base plate 1. A C-shaped frame 3 is horizontally slidably installed between the two sidewalls 2, forming a box structure. Wiring holes 301 are provided in the middle of the upper and lower surfaces of the C-shaped frame 3. A wiring terminal 4 is installed in the middle of the C-shaped frame 3 for wiring. In a specific implementation, sliding grooves 302 are provided on the top and bottom outer sides of the C-shaped frame 3. A horizontal sliding rib 202 is fixed on one side of the two sidewalls 2 corresponding to the position of the sliding groove 302. The sliding rib 202 and the sliding groove 302 slide horizontally together, forming a sliding installation of the C-shaped frame 3.

[0034] A sealing door 201 is hinged to one edge of one of the two side walls 2. The sealing door 201 is used to cover the opening of the C-shaped frame 3 and, together with the two side walls 2, forms a seal on the terminal block 4.

[0035] Cooperate Figure 3 and Figure 4As shown, a circular ring 5 is installed in the middle of the upper and lower end faces of the C-shaped frame 3. The ring 5 is installed on the outside of the port of the wiring hole 301. Several arc-shaped blades 501 are movably installed in the middle of the ring 5. A limiting bracket 502 for retracting the arc-shaped blades 501 is rotatably installed in the middle of the ring 5 to form a camera aperture structure. A sealing sleeve 503 for fitting on the cable is fitted at the opening of the ring 5. The sealing sleeve 503 can be a rubber sleeve with a certain elasticity or a wrapped adhesive tape, so that the arc-shaped blades 501 retract and abut against the outer edge of the sealing sleeve 503 to form a seal.

[0036] Specifically, such as Figure 4 As shown, the arc-shaped blade 501 has an arc structure. One end of the arc-shaped blade 501 is movably connected to the inner hole ring 5, and the other end of the arc-shaped blade 501 is slidably engaged with the limiting frame 502. A lever extending out of the hole ring 5 is fixed on the outer edge of the limiting frame 502. An arc-shaped through groove for the lever to slide horizontally is provided on the outer side of the hole ring 5. Therefore, the limiting frame 502 can be rotated by the lever outside the hole ring 5, thereby driving several arc-shaped blades 501 to move and adjust the hole diameter in the middle of the hole ring 5 to adapt to cables of different specifications.

[0037] The working principle provided by this utility model is that, during the use of this high-sealing junction box, when the operator is wiring, the C-shaped frame 3 can be pulled out from between the two side walls 2 to expose the wiring terminals 4, which increases the working space. Compared with the prior art, which requires wiring operations to be performed in a narrow box, this device has a wider operating space and is more convenient to use.

[0038] Meanwhile, since the aperture ring 5 adopts a camera aperture structure, it can adjust the size of the aperture in the middle of the aperture ring 5 by rotating the limiting bracket 502 to drive the arc blade 501 to adapt to different cable diameters. It also works with the sealing sleeve 503 to be put on the cable and abut against the arc blade 501 to form a seal, so that the device can adapt to different cable specifications for sealed installation.

[0039] In summary, this device is flexible and convenient to use, can be adapted to the sealed installation of cables of different specifications, and has a good overall performance.

[0040] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
