Description

Technical Field

[0001] This utility model relates to the field of four-in-one integrated terminal technology, specifically a novel four-in-one integrated terminal shell structure. Background Technology

[0002] The four-in-one integrated terminal boasts advantages such as small size, high functional integration, and convenient installation. It integrates high-precision metering, full-data acquisition, photovoltaic protocol conversion, leakage current monitoring, communication, edge computing, reclosing and residual current monitoring, and topology identification. It is suitable for autonomous energy edge management in distribution transformer areas, photovoltaic "four-in-one management," load regulation, and digital construction of distribution transformer areas. However, conventional four-in-one integrated terminals generally require the addition of electrical components based on the number of phases, resulting in inconsistent structures and hindering mass production. Utility Model Content

[0003] To address the issue that different phase terminals have different numbers of electrical components, thus making their housing structures incompatible, this invention provides a novel four-integrated terminal housing structure.

[0004] The technical solution of this utility model is as follows:

[0005] A novel four-integrated terminal housing structure includes a first housing, an intermediate housing, and a second housing arranged sequentially and detachably connected. The adjacent surfaces of the first housing and the intermediate housing, and the intermediate housing and the second housing, cooperate to form a cavity for placing electrical components.

[0006] The surface of the intermediate shell away from the first shell has the same structure as the surface of the first shell near the intermediate shell, and the surface of the intermediate shell away from the second shell has the same structure as the surface of the second shell near the intermediate shell.

[0007] The first housing and the second housing have a first mounting base and a second mounting base disposed opposite to each other on their adjacent surfaces. The intermediate housing has a first mounting base and a second mounting base disposed opposite to the adjacent surfaces of the first housing and the second housing, and a switch assembly is disposed between the adjacent first mounting bases and the second mounting bases of the different housings.

[0008] Unlike existing shell structures, the shell is divided into three parts, with the middle shell being adaptable to any other shell structure, thus enabling universality. In this way, structural changes can be made for different numbers of phases, requiring only the addition of a universal shell without the need to redesign the mold.

[0009] To accommodate different numbers of phases, several intermediate shells are sequentially arranged between the first and second shells. Stacking the intermediate shells can accommodate different numbers of phases without requiring additional shell structures that need to be molded.

[0010] The specific structure of the above-mentioned switch assembly is as follows: the switch assembly includes a switch body and torsion springs and driven members disposed on both sides of the switch body, wherein the torsion springs are in contact with the first mounting base, and the rotation of the driven members is limited by the second mounting base.

[0011] The specific structure of the switch body is as follows: the switch body includes a rotating column that abuts against the torsion spring and the driven member and is rotatable, and a lever is provided on the side of the rotating column away from the housing.

[0012] In order to control opening and closing simultaneously, the levers of adjacent switch bodies are fastened together by connectors and can rotate synchronously.

[0013] As a preferred embodiment, the paddle is provided with anti-slip texture.

[0014] The switch body controls the electrical components by having a socket provided along the rotation axis of the switch body. The socket is offset from the rotation axis and is used to connect the trigger of the electrical component.

[0015] As a preferred embodiment, the first mounting base and the second mounting base of the intermediate housing are coaxially arranged but not through each other.

[0016] The beneficial effects of this utility model are as follows: This utility model is a novel four-integrated terminal housing structure, which is different from the existing structure. The first housing and the second housing are the basic housing structures required for any number of phases, while the intermediate housing can be increased or decreased in number according to the actual number of phases and is set between the first housing and the second housing to form a complete terminal housing structure. Moreover, the switch of the above-mentioned terminal can be opened and closed synchronously through the connector. In this way, the assembly requirements of terminal housings with all phases can be completed by opening three molds, and the structural components can be freely interchanged, thus facilitating standardization.

[0026] like Figure 1 The present invention discloses a novel four-integrated terminal housing structure, comprising a first housing 1, an intermediate housing 2, and a second housing 3 arranged sequentially and detachably connected. The first housing 1 and the second housing 3 are reference housings, and the two housings can be directly combined for use. However, the design of the intermediate housing 2 ensures that the terminal housing can be adapted to the terminal design requirements of different number of phases. Furthermore, the adjacent surfaces of the first housing 1 and the intermediate housing 2, and the intermediate housing 2 and the second housing 3 cooperate to form a cavity for placing electrical components.

[0027] It should be noted that in the above structure, the surface of the intermediate shell 2 away from the first shell 1 has the same structure as the surface of the first shell 1 near the intermediate shell 2, and the surface of the intermediate shell 2 away from the second shell 3 has the same structure as the surface of the second shell 3 near the intermediate shell 2, such as... Figure 2 As shown, it is more convenient to design molds, and the intermediate shell 2 adopts this design method to ensure that it can cooperate with the first shell 1 or the second shell 3 to ensure that the structure of the above combined cavity is exactly the same. Therefore, when setting electrical components, the method is universal and the effect is the same. Through the above method, standardization can be easily achieved, which facilitates the assembly and use of terminal equipment.

[0028] Subsequently, in order to ensure that switching control can be performed, a first mounting base 6 and a second mounting base 7 are provided opposite to each other on the adjacent surfaces of the first housing 1 and the second housing 3. The design of the first mounting base 6 and the second mounting base 7 also follows the above idea. Therefore, the intermediate housing 2 is provided with a first mounting base 6 and a second mounting base 7 that cooperate with it on the adjacent surfaces of the first housing 1 and the second housing 3. A switch assembly 4 is provided between the adjacent first mounting base 6 and the second mounting base 7 of different housings. In this way, it can be achieved that no matter how many intermediate housings 2 are provided between the first housing 1 and the second housing 3, the switch assembly 4 of the same specification can be used.

[0029] Furthermore, in order to accommodate different number of phases, several intermediate housings 2 are sequentially arranged between the first housing 1 and the second housing 3 when the aforementioned terminal housing is in use. Stacking the intermediate housings 2 can accommodate different number of phases without requiring additional housing structures that need to be molded. During the design process, the corresponding number of intermediate housings 2 can be selected according to the number of phases required.

[0030] The above structure can achieve the desired effect. Unlike existing shell structures, the shell is divided into three parts, with the middle shell 2 being adaptable to any other shell structure, thus making it universal. In this way, it is possible to change the structure for different numbers of phases by simply adding a universal shell, without redesigning the mold. After determining the number of phases, it is only necessary to select the corresponding number of middle shells 2 and stack them. With this device, the arrangement of electrical components is also constant, so they can be freely arranged in each cavity. The switching structure is also universal, which is convenient for production and use.

[0031] And, as Figure 3-5 As shown, the specific structure of the switch assembly 4 is as follows: the switch assembly 4 includes a switch body 41 and torsion springs 42 and driven members 43 arranged on both sides of the switch body 41. The torsion springs 42 are in contact with the first mounting base 6, and the other end of the torsion springs 42 is in contact with the switch body 41. In this way, the switch body 41 can be reset relative to the first mounting base 6, and the rotation of the driven member 43 is limited by the second mounting base 7. The switch assembly 4 can be arranged in this way. It can be seen that the design of the switch assembly 4 is also used in conjunction with the first mounting base 6 and the second mounting base 7. Therefore, it can be mass-produced and arranged in the corresponding quantity according to the needs, and the structural position does not need to be changed.

[0032] And such as Figure 3 As shown, the specific structure of the switch body 41 is as follows: the switch body 41 includes a rotating column 411 that abuts against the torsion spring 42 and the driven member 43 and is rotatable; a lever 412 is provided on the side of the rotating column 411 away from the housing, and the switch is opened and closed by means of the lever 412. Furthermore, in order to control opening and closing simultaneously, the levers of adjacent switch bodies 41 are fastened together by a connector 5, enabling them to rotate synchronously. Figure 4 As shown, if there is a need to control the opening and closing of the switches simultaneously, this can be achieved through the connector 5. Furthermore, since the switch bodies 41 have the same structure, the connection structure between the connector 5 and each switch body 41 is also the same.

[0033] However, it should be noted that in the above structure, the paddle is equipped with anti-slip texture for ease of use.

[0034] Finally, as Figure 5As shown, in the above structure, the way to realize the control of electrical components by the switch body 41 is that the switch body 41 has a socket along the rotation axis, the socket is set off from the rotation axis and the trigger 8 of the electrical component is inserted.

[0035] To avoid communication between each cavity, the first mounting base 6 and the second mounting base 7 of the intermediate housing 2 are coaxially arranged but not connected.
