Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electrical equipment, and in particular to a housing and a rail meter. Background Art

[0002] The rail meter is short for the rail-mounted electricity meter. The rail meter includes a circuit board and a terminal block. The terminal block is used to connect the wires on the external circuit. A sampling component is provided on the circuit board, and the sampling component is connected to the terminal block for collecting electrical signals such as voltage and current in the external circuit.

[0003] Currently, the general plug-in type terminal blocks used in the rail meters on the market are used as voltage and current input ends. When connecting wires to the terminal blocks, it is often difficult to determine the position of the end of the wire, resulting in the possibility that the wire may contact the circuit board, affecting the circuits and electrical signals on the circuit board. Summary of the Utility Model

[0004] In view of the above problems, the embodiments of the present application provide a housing and a rail meter, which can isolate the circuit board and the terminal block to prevent the wire from contacting the circuit board.

[0005] According to one aspect of the embodiments of the present application, a housing is provided. The housing includes a base and an upper cover. The base is provided with a main body cavity and a wiring cavity. A cavity partition is provided between the main body cavity and the wiring cavity. The main body cavity is used to install the circuit board, and the wiring cavity is used to install the terminal block. A notch is provided on the cavity partition for the sampling component on the circuit board to extend into the wiring cavity; the upper cover includes a cover plate and a support plate. The support plate is provided on the inner side of the cover plate. The cover plate covers the base, and the support plate is inserted into the notch. A passage is provided between the end of the support plate and the bottom of the notch for the sampling component to pass through.

[0006] By adopting the above solution, the circuit board is installed in the main body cavity, and the terminal block is installed in the wiring cavity. The cavity partition can initially isolate the circuit board and the terminal block. The cover plate covers the base, so that a relatively closed space is formed inside the housing. The support plate is inserted into the notch on the cavity partition, which can further isolate the circuit board and the terminal block. When the wire of the external circuit is inserted into the wiring cavity and connected to the terminal block, if the wire is inserted too deep, it will be blocked by the cavity partition or the support plate and it will be difficult to continue inserting, thereby preventing the wire from being inserted too deep and contacting the circuit board. This ensures the accuracy of the electrical signals received by the circuit board. The setting that the support plate is inserted into the notch on the cavity partition enables the support plate to form an auxiliary positioning structure between the upper cover and the base through the cooperation with the notch, which is beneficial to the rapid installation of the upper cover and the base and improves the assembly efficiency of the housing.

[0007] In some embodiments, both sides of the support plate are in contact with and limited by both sides of the notch.

[0008] By adopting the above - mentioned solution, the cooperation between the support plate and the side wall of the notch is closer, forming a more accurate positioning for the upper cover and the base, and further preventing the wire from passing through between the support plate and the side wall of the notch, forming a more strict isolation for the main body cavity and the wiring cavity.

[0009] In some embodiments, shoulders are convexly provided on both sides of the bottom of the notch. The end of the support plate abuts against the shoulders, and one end of the sampling member located in the wiring cavity can abut against the side of the shoulder close to the wiring cavity.

[0010] By adopting the above - mentioned solution, the support plate abuts against the shoulders, and the shoulders limit the depth of insertion of the support plate into the notch; the sampling member passes through between the support plate and the bottom of the notch, and the shoulders can be used to limit the position of the sampling member from both sides of the sampling member, reducing the amplitude of the sampling member's swaying between the two shoulders. One end of the sampling member located in the wiring cavity abuts against the side of the shoulder close to the wiring cavity, so that the shoulders can also limit the movement of the sampling member in the direction of the main body cavity. Therefore, the setting of the shoulders serves the purpose of restricting the sampling member from multiple directions and reducing the swaying of the sampling member.

[0011] In some embodiments, the base further includes isolation baffles. The isolation baffles are arranged in the wiring cavity and are arranged side by side along the length direction of the wiring cavity. The multiple isolation baffles divide the wiring cavity into multiple independent cavities, and each independent cavity is used to connect a wiring terminal.

[0012] By adopting the above - mentioned solution, the wiring terminals in each independent cavity are insulated from each other by the isolation baffles, avoiding short - circuit between adjacent wiring terminals.

[0013] In some embodiments, one end of the isolation baffle close to the upper cover protrudes from the edge of the base, and the protruding part abuts against the edge of the upper cover.

[0014] By adopting the above - mentioned solution, the isolation baffle can not only isolate multiple wiring terminals, but also realize the positioning between the base and the upper cover by abutting against the edge of the upper cover, which is beneficial to the rapid positioning and assembly of the upper cover and the base, improves the assembly efficiency of the upper cover and the base, and can also prevent relative swaying after the upper cover and the base are assembled.

[0015] In some embodiments, the upper cover further includes screw cylinders. The screw cylinders are arranged inside the cover plate and are used to connect wiring screws. The screw cylinders are arranged in one - to - one correspondence with the independent cavities, and the isolation baffles are inserted into the gaps between adjacent screw cylinders.

[0016] By adopting the above - mentioned solution, the wiring screws are used to connect the wiring terminals and external wires. The isolation baffles are inserted into the gaps between adjacent screw cylinders, so that the isolation baffles can completely isolate adjacent wiring terminals and can also isolate the parts of adjacent wiring screws exposed outside the screw cylinders. In addition, the isolation baffles inserted into the gaps between adjacent screw cylinders can also play a role in positioning the upper cover and the base.

[0017] In some embodiments, the support plates and the screw cylinders are arranged in one-to-one correspondence, and there are at least two connection points between the support plates and the screw cylinders.

[0018] By adopting the above solution, the connection between the support plate and the screw cylinder is more firm and reliable, preventing the support plate and / or the screw cylinder from being broken by external forces during transportation or use of the housing.

[0019] In some embodiments, the base further includes a connecting column, a threaded hole is provided on the side of the connecting column close to the upper cover, and a through hole is provided on the upper cover; the housing further includes a connecting bolt, and the connecting bolt passes through the through hole on the upper cover and is connected in the threaded hole; the upper cover further includes an edge partition, the edge partition is arranged inside the cover plate, and an arc-shaped groove adapted to the outer wall portion of the connecting column is provided on the edge partition, and the arc-shaped groove abuts against the outer wall of the connecting column.

[0020] By adopting the above solution, the connecting bolt passes through the through hole on the upper cover and is connected in the threaded hole, which can realize the connection between the upper cover and the base. The arc-shaped groove on the edge partition abuts against the outer wall of the connecting column, which can play the role of positioning the upper cover and the base. During the assembly process of the upper cover and the base, this positioning structure can realize the rapid positioning of the upper cover and the base, improving the assembly efficiency of the upper cover and the base.

[0021] In some embodiments, the upper cover further includes two fixed retaining strips, the two fixed retaining strips are arranged inside the upper cover, and the space between the two fixed retaining strips is used to accommodate the wiring part on the circuit board, and a wiring hole is provided on the upper cover between the two fixed retaining strips.

[0022] By adopting the above solution, the wiring part on the circuit board is arranged between the two fixed retaining strips. When the wiring screw extends into the main body cavity from the wiring hole to connect the wiring part, the wiring part is not easily rotated, thereby reducing the stress on the connection point between the wiring part and the circuit board, and further reducing the risk of disconnection of the connection point between the wiring part and the circuit board, improving the product quality of the rail meter.

[0023] According to another aspect of the embodiments of the present application, a rail meter is provided, including the housing in any of the above embodiments, and further including a wiring terminal and a circuit board, the wiring terminal is arranged in the wiring cavity; the circuit board is arranged in the main body cavity, and a sampling component is connected to the circuit board, and the sampling component penetrates into the wiring cavity from between the end of the support plate and the bottom of the notch.

[0024] In the embodiment of the present application, by providing a support plate on the upper cover, and inserting the support plate into the notch on the cavity partition, the support plate cooperates with the cavity partition to isolate the circuit board and the terminal. When the wire of the external circuit is inserted into the wiring cavity to connect with the terminal, if the wire is inserted too deep, it will be blocked by the cavity partition or the support plate and it will be difficult to continue inserting, thereby preventing the wire from being inserted too deep and contacting the circuit board. This ensures the accuracy of the electrical signals received by the circuit board. In addition, the setting of inserting the support plate into the notch on the cavity partition enables the support plate to form an auxiliary positioning structure between the upper cover and the base through cooperation with the notch, which is conducive to the rapid installation of the upper cover and the base and improves the assembly efficiency of the housing.

[0025] The above description is only an overview of the technical solution of the embodiment of the present application. In order to be able to understand the technical means of the embodiment of the present application more clearly, it can be implemented according to the content of the description.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0043] When the guide rail table is in use, wires in the circuit need to be connected to the terminal. When the existing guide rail table connects wires to the terminal, the position of the end of the wire is often difficult to determine, resulting in the possibility that the wire may be inserted too deep and contact the circuit board, affecting the circuit and electrical signals on the circuit board.

[0044] In view of the above problems, an embodiment of the present application provides a housing. Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 . The housing includes a base 100 and an upper cover 200.

[0045] As Figure 1 and Figure 2 shown, the base 100 is provided with a main body cavity 110 and a wiring cavity 120. A cavity partition 130 is provided between the main body cavity 110 and the wiring cavity 120. The main body cavity 110 is used for installing a circuit board 300, and the wiring cavity 120 is used for installing a wiring terminal 400. A notch 131 is provided on the cavity partition 130 for a sampling member 310 on the circuit board 300 to extend into the wiring cavity 120;

[0046] As Figure 1 , Figure 3 and Figure 4 described, the upper cover 200 includes a cover plate 210 and a support plate 220. The support plate 220 is provided inside the cover plate 210. The cover plate 210 covers the base 100. The support plate 220 is inserted into the notch 131, and the space between the end of the support plate 220 and the bottom of the notch 131 is for the sampling member 310 to pass through.

[0047] As Figure 2 shown, the base 100 is used to carry almost all the parts inside the guide rail table. The base 100 includes a bottom plate 140 and a circle of lower frame 150 provided on the bottom plate 140. The cavity partition 130 is arranged in the area surrounded by the lower frame 150, dividing the space surrounded by the lower frame 150 into a main body cavity 110 and a wiring cavity 120. A wire insertion hole 160 is provided on the lower frame 150 corresponding to the wiring cavity 120 for a wire to extend in. The bottom plate 140, the lower frame 150 and the cavity partition 130 can be integrally injection molded.

[0048] As Figure 5 shown, the main body cavity 110 is used for installing a circuit board 300, and the circuit board 300 is used for collecting the electrical signals of the circuit connected to the wiring terminal 400. Exemplarily, steps for installing the circuit board 300 can be provided on the inner wall of the main body cavity 110 to fix the circuit board 300.

[0049] As Figure 5 shown, the wiring cavity 120 is used for installing a wiring terminal 400. The wiring terminal 400 can be a square metal part, such as an iron-clad part. Opposite ends of the iron-clad part are provided with openings. One of the openings faces the wire insertion hole 160 on the lower frame 150 for a wire to be inserted, and the other opening faces the gap between the end of the support plate 220 and the bottom of the notch 131 for the sampling member 310 to be inserted.

[0050] The sampling component 310 can be a copper strip welded to the circuit board 300, and the embodiments of the present application do not limit the sampling component 310.

[0051] The cavity partition 130 can initially isolate the circuit board 300 and the terminal 400, preventing the terminal 400 and the circuit board 300 from being electrically connected through parts other than the sampling component 310.

[0052] The cover plate 210 of the upper cover 200 covers the base 100, forming a relatively enclosed space inside the housing. The support plate 220 is inserted into the notch 131 on the cavity partition 130, which can further isolate the circuit board 300 and the terminal 400. When the wire of the external circuit is inserted into the wiring cavity 120 and connected to the terminal 400, if the wire is inserted too deeply, it will be blocked by the cavity partition 130 or the support plate 220 and it will be difficult to continue inserting, thereby preventing the wire from being inserted too deeply and contacting the circuit board 300, ensuring the accuracy of the electrical signals received by the circuit board 300.

[0053] It can be understood that the upper cover 200 can also include a circular upper frame 230, and the upper frame 230 protrudes from the inner edge of the cover plate 210. When the upper cover 200 is assembled with the base 100, the upper frame 230 abuts against the end of the lower frame 150. The cover plate 210, the upper frame 230 and the support plate 220 can be integrally injection-molded.

[0054] The arrangement that the support plate 220 is inserted into the notch 131 on the cavity partition 130 enables the support plate 220 to form an auxiliary positioning structure between the upper cover 200 and the base 100 through cooperation with the notch 131, which is beneficial to the rapid installation of the upper cover 200 and the base 100 and improves the assembly efficiency of the housing.

[0055] In the above embodiments, the inner side of the cover plate 210 or the inner side of the upper cover 200 refers to the side of the cover plate 210 or the upper cover 200 close to the base 100. Similarly, in the following text, the inner side of the base 100 refers to the side of the base 100 close to the upper cover 200.

[0056] Among them, the two sides of the support plate 220 can be in contact with the two sides of the notch 131, or there can be a certain gap. These two settings have different positioning degrees for the upper cover 200 and the base 100, but both can achieve the positioning of the upper cover 200 and the base 100 to a certain extent, achieving the effect of improving the assembly efficiency of the housing.

[0057] Exemplarily, as Figure 4 shown, in some embodiments, the two sides of the support plate 220 are in contact with and limited by the two sides of the notch 131.

[0058] By adopting the above solution, the cooperation between the support plate 220 and the side wall of the notch 131 is closer, forming a more accurate positioning of the upper cover 200 and the base 100, and further preventing the wire from passing through between the support plate 220 and the side wall of the notch 131, forming a more strict isolation between the main body cavity 110 and the wiring cavity 120.

[0059] As Figure 2 and Figure 4 shown, in some embodiments, shoulders 132 are protrudingly provided on both sides of the bottom of the notch 131. The end of the support plate 220 abuts against the shoulders 132, and one end of the sampling member 310 located in the wiring cavity 120 can abut against the side of the shoulders 132 close to the wiring cavity 120.

[0060] In the case where the sampling member 310 is relatively narrow, if the notch 131 is set relatively wide, the sampling member 310 may shake within the notch 131.

[0061] The shoulders 132 are structures protruding from the bottom of the notch 131. By providing the shoulders 132, the two sides of the sampling member 310 are limited by the shoulders 132 under the condition that the width of the support plate 220 and the width of the notch 131 remain unchanged. In this case, the four sides of the sampling member 310 are respectively restricted by the support plate 220, the bottom of the notch 131 and the two shoulders 132. The sampling member 310 is not easy to shake and its position is not easy to change. The connection between the sampling member 310 and the circuit board 300 is also relatively reliable. One end of the sampling member 310 located in the wiring cavity 120 abuts against the side of the shoulders 132 close to the wiring cavity 120, so that the shoulders 132 can also limit the movement of the sampling member 310 in the direction of the main body cavity 110. Therefore, the setting of the shoulders 132 serves the purpose of restricting the sampling member 310 from multiple directions and reducing the shaking of the sampling member 310.

[0062] The support plate 220 abuts against the shoulders 132. The shoulders 132 can limit the insertion depth of the support plate 220 into the notch 131 and can reduce the possibility of the end of the support plate 220 shaking through abutment.

[0063] As Figure 2 and Figure 4 shown, in some embodiments, the base 100 further includes isolation baffles 180. The isolation baffles 180 are arranged in the wiring cavity 120 and are arranged side by side along the length direction of the wiring cavity 120. The plurality of isolation baffles 180 divide the wiring cavity 120 into a plurality of independent cavities, and each independent cavity is used to connect a wiring terminal 400.

[0064] The isolation baffles 180 are baffles made of insulating materials, which can be integrally formed with the cavity partition 130 or assembled to the cavity partition 130. The embodiments of the present application do not limit this.

[0065] By adopting the above solution, the terminal blocks 400 in each independent cavity are insulated from each other by the isolation baffle 180, avoiding short circuits between adjacent terminal blocks 400.

[0066] In some embodiments, one end of the isolation baffle 180 close to the upper cover 200 protrudes beyond the edge of the base 100, and the protruding part abuts against the edge of the upper cover 200.

[0067] When the upper cover 200 includes an upper frame 230, the isolation baffle 180 abuts against the inner side of the upper frame 230, thereby restricting the positions of the upper cover 200 and the base 100 in the inner and outer directions of the upper frame 230.

[0068] When there are multiple isolation baffles 180, the number of isolation baffles 180 that meet the structure where one end of the isolation baffle 180 close to the upper cover 200 protrudes beyond the edge of the base 100 and the protruding part abuts against the edge of the upper cover 200 can be one or more, and the embodiments of the present application do not limit this.

[0069] By adopting the above solution, the isolation baffle 180 can not only isolate multiple terminal blocks 400, but also realize the positioning between the base 100 and the upper cover 200 by abutting against the edge of the upper cover 200. During the assembly process of the upper cover 200 and the base 100, it is beneficial to quickly position and assemble the upper cover 200 and the base 100, improving the assembly efficiency of the upper cover 200 and the base 100. After the upper cover 200 and the base 100 are assembled, it can prevent the upper cover 200 and the base 100 from shaking relative to each other.

[0070] Such as Figure 3 、 Figure 5 and Figure 6 As shown, in some embodiments, the upper cover 200 further includes screw barrels 240. The screw barrels 240 are arranged inside the cover plate 210 and are used to connect the wiring screws 500. The screw barrels 240 are arranged in one-to-one correspondence with the independent cavities, and the isolation baffle 180 is inserted into the gap between two adjacent screw barrels 240.

[0071] The screw barrel 240 is a cylindrical structure arranged on the cover plate 210. The arrangement of the cylindrical structure can not only allow the wiring screw 500 to pass through, but also provide a certain direction fixation for the wiring screw 500, so that the wiring screw 500 will not shift in position during rotation.

[0072] Such as Figure 5 As shown, when the wiring screw 500 is installed in the screw barrel 240, one end of it located in the independent cavity can be threadedly connected to the terminal block 400. In this way, as the wiring screw 500 rotates, the terminal block 400 can move up and down along the wiring screw 500.

[0073] Exemplarily, such asFigure 5 As shown, the part of the sampling member 310 located in the independent cavity is located in the inner cavity of the terminal 400. When wiring is required, the end of the wire is inserted into the inner cavity of the terminal 400 from the wire insertion hole 160, and the wiring screw 500 is rotated so that the terminal 400 moves along the wiring screw 500 while the position of the sampling member 310 remains unchanged. The movement of the terminal 400 drives the wire to move until the inner cavity wall of the terminal 400 presses the wire against the sampling member 310, realizing the electrical connection between the terminal 400 and the wire, as well as the sampling member 310.

[0074] As Figure 2 and Figure 4 shown, the isolation baffle 180 is inserted into the gap between two adjacent screw cylinders 240, so that the isolation baffle 180 can completely isolate adjacent terminals 400, and can also isolate the parts of adjacent wiring screws 500 exposed outside the screw cylinders 240. In addition, the isolation baffle 180 inserted into the gap between two adjacent screw cylinders 240 can also play a role in positioning the upper cover 200 and the base 100.

[0075] As Figure 3 and Figure 6 shown, in some embodiments, the support plates 220 and the screw cylinders 240 are arranged in one-to-one correspondence, and the support plates 220 and the screw cylinders 240 have at least two connection points.

[0076] The support plates 220 and the screw cylinders 240 are arranged in one-to-one correspondence, and the screw cylinders 240 and the independent cavities are arranged in one-to-one correspondence. The independent cavities are used to install the terminals 400. Therefore, it is equivalent to that the support plates 220 and the terminals 400 are arranged in one-to-one correspondence. And each terminal 400 is used to connect external wires. Therefore, the support plates 220 can prevent the wires from penetrating at each terminal 400 and prevent the wires from contacting the circuit board 300.

[0077] The above connection points are points in a broad sense, referring to connection positions. The connection area of each connection position can be large or small, and the embodiments of the present application do not limit this.

[0078] Compared with the setting where the support plates 220 and the screw cylinders 240 are independently arranged, or the setting where the support plates 220 and the screw cylinders 240 have only one connection point, the setting where the support plates 220 and the screw cylinders 240 have at least two connection points makes the connection between the support plates 220 and the screw cylinders 240 more firm and reliable. The two can support and reinforce each other, preventing the support plates 220 and / or the screw cylinders 240 from breaking due to external forces during transportation or use of the housing.

[0079] As Figure 4 and Figure 6As shown, in some embodiments, the base 100 further includes a connecting column 170. A screw hole 171 is provided on the side of the connecting column 170 close to the upper cover 200, and a through hole 250 is provided on the upper cover 200. The housing further includes a connecting bolt 600, and the connecting bolt 600 passes through the through hole 250 on the upper cover 200 and is connected in the screw hole 171. The upper cover 200 further includes an edge partition 260. The edge partition 260 is arranged inside the cover plate 210, and an arc-shaped groove 261 adapted to the outer wall portion of the connecting column 170 is provided on the edge partition 260, and the arc-shaped groove 261 abuts against the outer wall of the connecting column 170.

[0080] The connecting bolt 600 passes through the through hole 250 on the upper cover 200 and is connected in the screw hole 171, which can realize the connection between the upper cover 200 and the base 100. The number of the connecting columns 170 is at least two, specifically, it can be 3, 4 or 5. Correspondingly, the numbers of the screw holes 171, the through holes 250 and the connecting bolts 600 are also the same as the number of the connecting columns 170.

[0081] The arc-shaped groove 261 on the edge partition 260 abuts against the outer wall of the connecting column 170, which can play the role of positioning the upper cover 200 and the base 100. During the assembly process of the upper cover 200 and the base 100, this positioning structure can realize the rapid positioning of the upper cover 200 and the base 100, and improve the assembly efficiency of the upper cover 200 and the base 100.

[0082] As Figure 3 and Figure 5 As shown, in some embodiments, the upper cover 200 further includes two fixed retaining strips 270. The two fixed retaining strips 270 are arranged inside the upper cover 200, and the wiring part 320 on the circuit board 300 is accommodated between the two fixed retaining strips 270. A wiring hole 280 is provided on the upper cover 200 between the two fixed retaining strips 270.

[0083] The wiring part 320 is usually welded to the circuit board 300. The wiring screw 500 passes through the wiring hole 280 and is connected to the wiring part 320. During the rotation of the wiring screw 500, a rotational torque is usually applied to the wiring part 320, so that the wiring part 320 has a tendency to rotate relative to the circuit board 300, which may cause the solder joint between the wiring part 320 and the circuit board 300 to break.

[0084] After the above-mentioned fixed retaining strips 270 are provided, the wiring part 320 is located between the two fixed retaining strips 270. When the wiring screw 500 applies a rotational torque to the wiring part 320, the wiring part 320 can abut against the fixed retaining strip 270, thereby transmitting the pressure to the fixed retaining strip 270. The force on the solder joint between the wiring part 320 and the circuit board 300 is reduced or not affected, thereby reducing the risk of disconnection of the connection point between the wiring part 320 and the circuit board 300 and improving the product quality of the guide rail meter.

[0085] In summary, in the embodiment of the present application, by providing a support plate 220 on the upper cover 200, and inserting the support plate 220 into the notch 131 on the cavity partition plate 130, the support plate 220 cooperates with the cavity partition plate 130, which can isolate the circuit board 300 and the terminal 400. When the wire of the external circuit is inserted into the wiring cavity 120 and connected to the terminal 400, if the wire is inserted too deep, it will be blocked by the cavity partition plate 130 or the support plate 220 and it is difficult to continue to be inserted, thereby preventing the wire from being inserted too deep and contacting the circuit board 300. This ensures the accuracy of the electrical signals received by the circuit board 300. In addition, the setting of inserting the support plate 220 into the notch 131 on the cavity partition plate 130 enables the support plate 220 to form an auxiliary positioning structure between the upper cover 200 and the base 100 through the cooperation with the notch 131, which is conducive to the rapid installation of the upper cover 200 and the base 100 and improves the assembly efficiency of the housing.

[0086] The embodiment of the present application also provides a guide rail meter, which includes the housing in any of the above embodiments, and further includes a terminal 400 and a circuit board 300. The terminal 400 is arranged in the wiring cavity 120; the circuit board 300 is arranged in the main body cavity 110, and a sampling member 310 is connected to the circuit board 300, and the sampling member 310 penetrates into the wiring cavity 120 from between the end of the support plate 220 and the bottom of the notch 131.
