Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a housing assembly and a circuit detection device. Background Art

[0002] With the digital transformation of the power industry, the demand for power monitoring in power grid systems and equipment circuits is increasing. For older power grids and equipment, digital upgrades are not only cost-prohibitive but also extremely difficult. Adding circuit monitoring devices to older power grids or equipment is a highly suitable and economical solution.

[0003] The circuit detection device needs to transmit data after detecting the circuit, which requires an antenna component to be provided in the circuit detection device. However, in the prior art, the antenna component is less efficient when installed in the circuit detection device. Utility Model Content

[0004] The present application provides a housing assembly and a circuit detection device, which improve the installation efficiency of the antenna assembly.

[0005] In a first aspect, the present application provides a housing assembly comprising a base and an antenna assembly. The base comprises a bottom plate and side plates, the side plates being connected to the bottom plate to form a receiving cavity. The side plates are provided with mounting structures comprising circular through-slots extending through the side plates. The antenna assembly comprises a connector, a first end of which extends through the circular through-slot and is positioned within the receiving cavity, while a second end of the connector is positioned outside the cavity. The mounting structure is capable of limiting the position of the connector.

[0006] Through the above scheme, the present application utilizes the combination of the side plate and the bottom plate to form a receiving cavity in the base, which can protect some components of the circuit detection device. The setting of the mounting structure allows the antenna assembly to be installed on the base. Compared with the D-shaped through-slot in the prior art, the circular through-slot does not require the antenna assembly to be aligned with the D-shaped through-slot before installation. This can reduce the difficulty of installing the antenna assembly and improve the assembly efficiency of the circuit detection device. Using the mounting structure to limit the antenna assembly can reduce the occurrence of the problem of the antenna assembly falling from the base, and can also reduce the occurrence of the problem of the antenna assembly rotating relative to the base, thereby improving the reliability of the circuit detection device.

[0007] In a possible design, the cross section of the connecting piece is circular, or the cross section of the connecting piece is D-shaped. The connecting piece and the circular through groove are interference fit.

[0008] The circular through-slot, as described above, reduces restrictions on the connector's shape during manufacturing. Regardless of the connector's shape, it can be fitted with the circular through-slot. This reduces the connector's production complexity and eliminates the need for matching the shape of the mounting structure, improving connector manufacturing efficiency and, consequently, antenna assembly manufacturing efficiency. The interference fit between the connector and the circular through-slot allows the mounting structure to position the connector, and the interference fit also offers advantages such as a simple structure and good centering properties.

[0009] In one possible design, a stopper is provided at the first end of the connector, abutting against a side of the side panel proximate to the accommodating cavity. The mounting structure also includes a fastener that is sleeved onto the second end of the connector. The fastener cooperates with the stopper to secure the position of the antenna assembly relative to the base.

[0010] With this solution, the stopper is positioned within the accommodating cavity and abuts against the side of the side panel closest to the accommodating cavity. This prevents the antenna assembly from falling from the base. Fasteners are provided outside the accommodating cavity, and the fasteners cooperate with the stopper to position the antenna assembly, reducing the rotation angle of the antenna assembly relative to the base. This improves the reliability of the antenna assembly, thereby enhancing the reliability of the circuit detection device.

[0011] In one possible design, a first end of the connector is provided with a limiting portion that abuts against a side of the side panel adjacent to the accommodating cavity. The mounting structure further includes a limiting block located within the accommodating cavity. The limiting portion abuts against the limiting block.

[0012] With the above solution, the stopper is positioned within the accommodating cavity and abuts against the side of the side panel closest to the accommodating cavity. This prevents the antenna assembly from falling from the base. Installing a stopper block and abutting the stopper allows the friction between the block and the stopper to limit the antenna assembly, reducing the rotation angle of the antenna assembly relative to the base. This improves the reliability of the antenna assembly and, consequently, the circuit detection device.

[0013] In one possible design, a limit block is provided, and the side panels include a first side panel and a second side panel, the first side panel and the second side panel being adjacent to each other. A circular through-slot is provided in the first side panel, the limit block is provided on a side of the circular through-slot away from the second side panel, and the limit portion further abuts the first side panel and the second side panel.

[0014] With the above solution, the limiting portion is disposed within the accommodating cavity and abuts against the side of the side panel proximal to the accommodating cavity. This limits the position of the antenna assembly in its installation direction, reducing the possibility of the antenna assembly falling from the base. The limiting portion also abuts against the limiting block and the second side panel. The friction generated by the limiting block and the second side panel on the limiting portion causes the limiting portion to be clamped between the limiting block and the second side panel, thereby limiting the position of the connector. This reduces the rotation angle of the antenna assembly relative to the base, thereby increasing the reliability of the antenna assembly.

[0015] In a possible design, two limiting blocks are provided, and the circular through groove is located between the two limiting blocks. The limiting portion abuts against the two limiting blocks at the same time.

[0016] With the above solution, the limiting portion simultaneously abuts against both limiting blocks, generating friction between the two limiting blocks and the limiting portion. This allows the two limiting blocks to clamp the limiting portion, thereby limiting the position of the connector. This reduces the rotation angle of the antenna assembly relative to the base, thereby increasing the reliability of the antenna assembly. Furthermore, using a second limiting block instead of the side plate to abut against the limiting portion reduces wear and tear on the side plate, thereby increasing the service life of the base. This also reduces the subsequent maintenance costs of the circuit detection device.

[0017] In a possible design, the limiting portion is a prismatic structure, and includes a first side surface and a second side surface, wherein the first side surface is in surface contact with the second side plate, and the second side surface is in surface contact with the limiting block.

[0018] The prismatic retaining portion of the aforementioned solution reduces the possibility of the connector rotating within the circular slot, thereby reducing the possibility of the antenna assembly rotating relative to the base and improving the reliability of the antenna assembly. Furthermore, the surface contact between the first side surface and the second side plate, and between the second side surface and the retaining block, increases the friction between the retaining portion, the retaining block, and the second side plate. This allows the retaining block and the second side plate to more securely clamp the retaining portion, thereby reducing the possibility of the connector rotating within the circular slot.

[0019] In a possible design, the limiting portion is a prismatic structure, and includes a first edge and a second edge. The first edge abuts against the second side plate, and the second edge abuts against the limiting block.

[0020] Through this solution, the prismatic retaining portion reduces the possibility of the connector rotating within the circular slot, thereby reducing the possibility of the antenna assembly rotating relative to the base and improving the reliability of the antenna assembly. Furthermore, the abutment between the first edge and the second side plate, and the abutment between the second edge and the retaining block, further stabilizes the retaining portion's position within the accommodating cavity, thereby reducing the possibility of the connector rotating within the circular slot.

[0021] In some possible designs, the mounting structure further includes a buckle, which is disposed in the circular through groove and can limit the position of the connector.

[0022] Through the above scheme, the buckle provided in the circular through groove can assist the circular through groove in limiting the connector, so as to reduce the probability of the connector moving out of the accommodating cavity, thereby improving the reliability of the connector and thus improving the reliability of the antenna assembly.

[0023] In a second aspect, the present application provides a circuit detection device, comprising a top cover and the housing assembly mentioned in the first aspect, wherein the top cover and the base of the housing assembly cover each other.

[0024] With this solution, the installation space formed by the top and bottom covers can accommodate and protect some components of the circuit detection device. The circuit detection device can be used in the digital upgrade of older power grids and equipment, thereby detecting parameters such as current, voltage, and power. By installing the circuit detection device, the cost and difficulty of upgrading older power grids and equipment can be reduced.

[0025] The beneficial effects of the circuit detection device provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, and will not be repeated here.

[0046] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0047] Figure 1 This is a schematic diagram of the overall structure of the circuit detection device provided in an embodiment of the present application. Figure 2 This is an assembly diagram of the base and wiring assembly provided in the embodiment of the present application. Figure 1 as well as Figure 2As shown, the present application provides a circuit detection device, comprising a top cover 300 and a housing assembly. The top cover 300 and the base 100 in the housing assembly cover each other.

[0048] Circuit detection devices can detect parameters such as current, voltage, and power in external circuits and upload the detected data. Circuit detection devices are often used for digital upgrades of older power grids and equipment.

[0049] A accommodating cavity may be provided inside the top cover 300, and a accommodating cavity may also be provided inside the base 100. After the top cover 300 and the base 100 are covered together, the accommodating cavity inside the top cover 300 may be combined with the accommodating cavity inside the base 100 to form an installation space, and some components of the circuit detection device may be arranged in the installation space.

[0050] In summary, the installation space formed by the top and bottom covers when closed can accommodate and protect some components of the circuit detection device. The circuit detection device can be used in the digital upgrade of older power grids and equipment, thereby detecting parameters such as current, voltage, and power. By installing the circuit detection device, the cost and difficulty of upgrading older power grids and equipment can be reduced.

[0051] The housing assembly mentioned in this application is described in detail below with reference to the accompanying drawings.

[0052] Figure 3 A schematic structural diagram of the base provided in an embodiment of the present application at one viewing angle. Figure 4 This is a schematic diagram of the structure of the antenna assembly provided in the embodiment of the present application. Figures 2 to 4 As shown, the present application provides a housing assembly including a base 100 and an antenna assembly 200. The base 100 includes a bottom plate 110 and a side plate 120. The side plate 120 is connected to the bottom plate 110, so that the base 100 forms a receiving cavity. A mounting structure 130 is provided on the side plate 120. The mounting structure 130 includes a circular through-slot 131 that passes through the side plate 120. The antenna assembly 200 includes a connector 210. The first end of the connector 210 passes through the circular through-slot 131 and is located in the receiving cavity, and the second end of the connector 210 is located outside the receiving cavity. The mounting structure 130 can limit the connector 210.

[0053] The bottom panel 110 can be plate-shaped, and the side panels 120 can be formed by connecting multiple plate-shaped structures end to end. The side panels 120 are connected to the bottom panel 110, and the space between the side panels 120 and the bottom panel 110 constitutes the receiving cavity. The circular through-slot 131 can be integrally formed with the side panels 120, or it can be provided on the side panels 120 after the side panels 120 are formed by carving or cutting.

[0054] Antenna assembly 200 can be used to send signals to an external receiver, transmitting the values measured by the current transformer and voltage transformer. Connector 210 can be part of antenna assembly 200. The first end of connector 210 can extend from outside the accommodating cavity through circular slot 131 into the accommodating cavity and connect to the circuit board 400 inside the accommodating cavity. The second end of connector 210 is located outside the accommodating cavity and connects to the component of antenna assembly 200 used for signal transmission.

[0055] The ability of the mounting structure 130 to limit the position of the connector 210 means that the mounting structure 130 can limit the position of the antenna assembly 200 in the installation direction of the antenna assembly 200 and / or the mounting structure 130 can limit the position of the antenna assembly 200 in the circumferential direction of the circular through-slot 131. The installation direction of the antenna assembly 200 is consistent with the direction in which the connector 210 extends from outside the accommodating cavity through the circular through-slot 131 into the accommodating cavity.

[0056] Mounting structure 130 limits the position of antenna assembly 200 in its installation direction, reducing the probability of antenna assembly 200 falling off base 100. Mounting structure 130 limits the position of the antenna assembly 200 in the circumferential direction of circular through-slot 131, reducing the rotation angle of antenna assembly 200 relative to base 100. This improves the reliability of antenna assembly 200.

[0057] In summary, the present application utilizes the combination of the side panels 120 and the bottom panel 110 to form a housing cavity on the base 100, which can protect some components of the circuit detection device. The provision of the mounting structure 130 enables the antenna assembly 200 to be mounted on the base 100. Compared to the D-shaped through-slot in the prior art, the circular through-slot 131 does not require the antenna assembly 200 to be aligned with the D-shaped through-slot before installation during the installation of the antenna assembly 200. This can reduce the difficulty of installing the antenna assembly 200 and improve the assembly efficiency of the circuit detection device. By using the mounting structure 130 to limit the antenna assembly 200, the occurrence of the problem of the antenna assembly 200 falling from the base 100 can be reduced, and the occurrence of the problem of the antenna assembly 200 rotating relative to the base 100 can be reduced, thereby improving the reliability of the circuit detection device.

[0058] Please continue to refer to Figure 3 as well as Figure 4 As shown, the cross section of the connecting member 210 is circular, or the cross section of the connecting member 210 is D-shaped. The connecting member 210 and the circular through groove 131 are interference fit.

[0059] The connecting member 210 may be cylindrical or may have an irregular cylindrical structure. The cross-sectional dimensions of the connecting member 210 may be the same as the inner diameter of the circular through-slot 131, or the cross-sectional dimensions of the connecting member 210 may be slightly larger than the inner diameter of the circular through-slot 131, thereby achieving an interference fit between the connecting member 210 and the circular through-slot 131.

[0060] In summary, the provision of circular through-slot 131 reduces restrictions on the shape of connector 210 during the manufacturing process. Regardless of the shape of connector 210, it can mate with circular through-slot 131. This reduces the difficulty of manufacturing connector 210 and eliminates the need for matching the shape of mounting structure 130, improving the manufacturing efficiency of connector 210 and, consequently, antenna assembly 200. The interference fit between connector 210 and circular through-slot 131 allows mounting structure 130 to position connector 210. This interference fit also offers advantages such as a simple structure and good centering properties.

[0061] Figure 5 An assembly diagram of the base and antenna assembly provided in an embodiment of the present application.

[0062] like Figure 2 、 Figure 4 as well as Figure 5 As shown, the first end of the connector 210 is provided with a stopper 211, which abuts against the side of the side panel 120 near the accommodating cavity. The mounting structure 130 also includes a fastener 132, which is sleeved on the second end of the connector 210. The fastener 132 cooperates with the stopper 211 to secure the position of the antenna assembly 200 relative to the base 100.

[0063] The first end is located within the accommodating cavity. The limiting portion 211 can be a raised structure provided on the first end. The cross-sectional area of the limiting portion 211 can be larger than the inner diameter of the circular through-slot 131. This can reduce the possibility of the connector 210 falling off the base 100. The side of the side panel 120 closest to the accommodating cavity serves as the side wall of the side panel 120 located within the accommodating cavity. When the connector 210 is installed on the base 100, the limiting portion 211 abuts against the side wall of the side panel 120 located within the accommodating cavity. This allows the side panel 120 and the limiting portion 211 to cooperate to limit the connector 210 in the installation direction of the antenna assembly 200.

[0064] The fastener 132 can be disposed outside the accommodating cavity and can be sleeved on the connector 210. The fastener 132 can be a nut, and the second end of the connector 210 can be provided with threads. The fastener 132 can limit the movement of the antenna assembly 200 into the accommodating cavity, and the limit portion 211 can limit the movement of the antenna assembly 200 out of the accommodating cavity. When the fastener 132 cooperates with the limit portion 211, the antenna assembly 200 can be fixed to the base 100.

[0065] Through the above arrangement, the stopper 211 is disposed within the accommodating cavity and abuts against the side of the side panel 120 proximal to the accommodating cavity. This prevents the antenna assembly 200 from falling off the base 100 by limiting its position in its installation direction. Fasteners 132 are disposed outside the accommodating cavity, and the fasteners 132 cooperate with the stopper 211 to limit the position of the antenna assembly 200, thereby reducing the rotation angle of the antenna assembly 200 relative to the base 100. This improves the reliability of the antenna assembly 200 and, consequently, the circuit detection device.

[0066] Please continue to refer to Figure 4 as well as Figure 5 As shown, the first end of the connector 210 is provided with a stopper 211, which abuts against the side of the side panel 120 near the receiving cavity. The mounting structure 130 also includes a stopper 133, which is located within the receiving cavity. The stopper 211 abuts against the stopper 133.

[0067] The structure of the limiting portion 211 has been described in detail above and will not be repeated here.

[0068] The limiting block 133 may be a protruding structure provided on the base 100. For example, the limiting block 133 may be provided on the bottom plate 110, or the limiting block 133 may be provided on the side plate 120.

[0069] With the above arrangement, the limiting portion 211 is disposed within the accommodating cavity and abuts against the side of the side panel 120 proximal to the accommodating cavity. This allows the antenna assembly 200 to be positioned in its installation direction, reducing the possibility of the antenna assembly 200 falling off the base 100. By installing the limiting block 133 and abutting the limiting portion 211, the friction between the limiting block 133 and the limiting portion 211 can be used to limit the position of the antenna assembly 200, thereby reducing the rotation angle of the antenna assembly 200 relative to the base 100. This improves the reliability of the antenna assembly 200 and, consequently, the reliability of the circuit detection device.

[0070] like Figure 5As shown, a stop block 133 is provided, and the side panel 120 includes a first side panel 121 and a second side panel 122, and the first side panel 121 is adjacent to the second side panel 122. A circular through-slot 131 is provided in the first side panel 121, and the stop block 133 is provided on a side of the circular through-slot 131 away from the second side panel 122. The stop portion 211 also abuts against the first side panel 121 and the second side panel 122.

[0071] The first side plate 121 and the second side plate 122 are arranged at a non-zero angle, and the angle between the first side plate 121 and the second side plate 122 can be 83°, 85°, or 90°, etc. The circular through-slot 131 is provided between the stop block 133 and the second side plate 122. When the first end of the connector 210 is located within the accommodating cavity, the stop portion 211 is located between the stop block 133 and the second side plate 122. The stop portion 211 abuts against both the stop block 133 and the second side plate 122.

[0072] Through the above arrangement, the limiting portion 211 is disposed within the accommodating cavity and abuts against the side of the side panel 120 proximal to the accommodating cavity. This allows the antenna assembly 200 to be positioned in its installation direction, reducing the possibility of the antenna assembly 200 falling off the base 100. The limiting portion 211 simultaneously abuts against the limiting block 133 and the second side panel 122. The friction generated by the limiting block 133 and the second side panel 122 on the limiting portion 211 causes the limiting portion 211 to be clamped between the limiting block 133 and the second side panel 122, thereby limiting the position of the connector 210. This reduces the rotation angle of the antenna assembly 200 relative to the base 100, thereby increasing the reliability of the antenna assembly 200.

[0073] 6 , there are two limit blocks 133 , and the circular through slot 131 is located between the two limit blocks 133 . The limit portion 211 abuts against the two limit blocks 133 at the same time.

[0074] The two limit blocks 133 can both be protruding structures provided in the accommodating cavity. The two limit blocks 133 can both be provided on the side plate 120, or both limit blocks 133 can be provided on the base 100, or one limit block 133 can be provided on the side plate 120 and the other limit block 133 can be provided on the base 100.

[0075] There may be a gap between the two limit blocks 133 , and the circular through groove 131 may be located in the gap. When the first end of the connector 210 is located in the accommodating cavity, the limit portion 211 is located in the gap between the two limit blocks 133 and abuts against the two limit blocks 133 at the same time.

[0076] With this arrangement, the limiting portion 211 simultaneously abuts against both limiting blocks 133, generating friction between the two limiting blocks 133 and the limiting portion 211. This allows the two limiting blocks 133 to clamp the limiting portion 211, thereby limiting the position of the connector 210. This reduces the rotation angle of the antenna assembly 200 relative to the base 100, thereby increasing the reliability of the antenna assembly 200. Furthermore, using the second limiting block 133 in place of the side plate 120 to abut against the limiting portion 211 reduces wear and tear on the side plate 120, thereby increasing the service life of the base 100. This also reduces the subsequent maintenance costs of the circuit detection device.

[0077] like Figure 4 as well as Figure 5 As shown, the limiting portion 211 is a prismatic structure, and includes a first side surface and a second side surface. The first side surface is in surface contact with the second side plate 122 , and the second side surface is in surface contact with the limiting block 133 .

[0078] The cross-section of the limiting portion 211 can be polygonal. The limiting portion 211 can be a quadrangular prism, a pentagonal prism, a hexagonal prism, etc. Because the limiting portion 211 is a prism structure, the limiting portion 211 can have multiple side surfaces, wherein the first side surface and the second side surface can be two of the multiple side surfaces.

[0079] When the first end of the connecting member 210 is located in the accommodating cavity, the limiting portion 211 is in contact with the second side plate 122 and the limiting block 133 at the same time. At this time, the first side surface can be in surface contact with the second side plate 122, and the second side surface can be in surface contact with the limiting portion 211.

[0080] Through the above arrangement, the prismatic stopper 211 can reduce the possibility of the connector 210 rotating within the circular slot 131, thereby reducing the possibility of the antenna assembly 200 rotating relative to the base 100 and improving the reliability of the antenna assembly 200. Furthermore, the surface contact between the first side surface and the second side plate 122, and the surface contact between the second side surface and the stopper 133, can increase the friction between the stopper 211, the stopper 133, and the second side plate 122. This allows the stopper 133 and the second side plate 122 to more firmly clamp the stopper 211, thereby reducing the possibility of the connector 210 rotating within the circular slot 131.

[0081] Please continue to refer to Figure 4 as well as Figure 5 As shown, the limiting portion 211 is a prismatic structure, and includes a first edge and a second edge. The first edge abuts against the second side plate 122 , and the second edge abuts against the limiting block 133 .

[0082] Because the limiting portion 211 is a prismatic structure, the limiting portion 211 may have a plurality of edges, wherein the first edge and the second edge may be two of the plurality of edges.

[0083] When the first end of the connecting member 210 is located in the accommodating cavity, the limiting portion 211 abuts against the second side plate 122 and the limiting block 133 at the same time. At this time, the second side plate 122 abuts against the first edge, and the other limiting block 133 abuts against the second edge.

[0084] Through the above arrangement, the prismatic limiting portion 211 can reduce the possibility of the connector 210 rotating within the circular slot 131, thereby reducing the possibility of the antenna assembly 200 rotating relative to the base 100 and improving the reliability of the antenna assembly 200. Furthermore, the abutment between the first edge and the second side plate 122 and the abutment between the second edge and the limiting block 133 can further stabilize the position of the limiting portion 211 within the accommodating cavity, thereby reducing the possibility of the connector 210 rotating within the circular slot 131.

[0085] like Figure 3 as well as Figure 4 As shown, the mounting structure 130 further includes a buckle, which is disposed in the circular through slot 131. The buckle can limit the connection member 210.

[0086] The buckle can be annular, and the diameter of the buckle can be the same as the diameter of the circular through groove 131, or the diameter of the buckle can be slightly larger than the diameter of the circular through groove 131. The buckle and the circular through groove 131 can be interference fit.

[0087] The buckle is provided with at least one hook in the direction of the receiving cavity. When the connector 210 is mounted on the base 100 , the hook can be bent toward the connector to limit the connector 210 .

[0088] Through the above-mentioned setting, the buckle provided in the circular through groove 131 can assist the circular through groove 131 to limit the connector 210, so as to reduce the probability of the connector 210 moving out of the accommodating cavity, thereby improving the reliability of the connector 210 and thus improving the reliability of the antenna assembly 200.
