[0028] 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 invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] See Figures 1-6 This utility model provides a light guide post mounting structure, including a light guide post 2 and a housing 1. The housing 1 has an inner cavity, and the light guide post 2 is located in the inner cavity. The housing 1 has at least one mounting hole 12, which communicates with the inner cavity. The light guide post 2 includes a connecting seat 21 and at least one light guide indicator post 22. The light guide indicator post 22 passes through the connecting seat 21, and one end of the light guide indicator post 22 is inserted into the mounting hole 12. The connecting seat 21 is pressed against the end wall of the mounting hole 12. The light guide post 2 is fixedly connected to the housing 1 by pressing the connecting seat 21 against the end wall of the mounting hole 12, which reduces the size requirements of the connecting seat 21. By setting the connecting seat 21 to a smaller size, the light guide post 2 can be fixed, which is conducive to the miniaturization of the light guide post 2, and thus facilitates the portable development of single-phase meters or data acquisition terminals.

[0030] The number of light guide posts 22 can be one, two, three, four, five, six or other values, and the number of mounting holes 12 is equal to the number of light guide posts 22, and they are set in a one-to-one correspondence.

[0031] Furthermore, the housing 1 is provided with at least one mounting post 11 extending into the inner cavity, the mounting hole 12 penetrates the mounting post 11, and the connecting seat 21 is pressed against the end wall of the mounting post 11. The mounting post 11 and the connecting seat 21 are pressed together, and the mounting post 11 has a hollow structure around it, which reduces the difficulty of the pressing process.

[0032] Specifically, the diameter of the mounting post 11 is less than twice the diameter of the mounting hole 12 to avoid the mounting post 11 being too large and affecting the installation of other components, thereby avoiding the single-phase meter or data acquisition terminal being too large.

[0033] Furthermore, the light guide indicator post 22 includes a first light guide segment 221, a second light guide segment 222, and a third light guide segment 223. The first light guide segment 221 is used to connect to the connecting seat 21. The second light guide segment 222 and the third light guide segment 223 are respectively connected to both ends of the first light guide segment 221. The second light guide segment 222 is inserted into the mounting hole 12. With the second light guide segment 222 inserted into the mounting hole 12 and its top wall exposed, light from the internal light source of the housing 1 can be transmitted to the outside, realizing visual display functions such as signal lights and status indicators.

[0034] Specifically, the connecting seat 21, the first light guide segment 221, the second light guide segment 222 and the third light guide segment 223 are integrally formed structures, requiring no other connection processes, resulting in high structural strength and good rigidity.

[0035] Furthermore, the connecting seat 21 includes at least one pressing plate 211, each pressing plate 211 being used to press against the end wall of a corresponding mounting post 11 to achieve a fixed connection between the connecting seat 21 and the mounting post 11, thereby achieving a fixed installation of the light guide post 2; the light guide indicator post 22 passes through the pressing plate 211, and the diameter of the pressing plate 211 is less than or equal to the diameter of the mounting post 11, which helps to reduce the volume of the connecting seat 21 and avoids the light guide post 2 from being too large due to the large volume of the connecting seat 21.

[0036] Furthermore, there are multiple mounting posts 11 and multiple light guide indicator posts 22. Each mounting post 11 is provided with a corresponding mounting hole 12, and each mounting hole 12 is provided with a corresponding light guide indicator post 22. Each light guide indicator post 22 extends from a mounting hole 12, realizing the visual display of various signal lights.

[0037] Furthermore, the plurality of mounting posts 11 are arranged in a straight line at intervals.

[0038] Furthermore, the length of the second light guide segment 222 is less than or equal to the length of the mounting hole 12, so as to prevent the second light guide segment 222 from being too long and protruding from the outer surface of the housing 1. The second light guide segment 222 is completely contained in the mounting hole 12. The light guide column 2 can both realize the indication function and be hidden, so as not to affect the use of the electricity meter or data collection terminal.

[0039] Furthermore, there are multiple pressing plates 211, with each light guide post 22 correspondingly inserted into one pressing plate 211. The connecting seat 21 also includes at least one connecting part 212, with each pair of adjacent pressing plates 211 connected by a connecting part 212. The width of the connecting part 212 is less than or equal to the diameter of the pressing plate 211. Multiple pressing plates 211 are connected together by the connecting part 212 to form an integral structure, and the top wall of the connecting part 212 is flush with the top wall of the pressing plate 211. When the connecting seat 21 is pressed against the housing 1, multiple pressing plates 211 can be simultaneously fixedly connected to multiple mounting posts 11, reducing installation steps.

[0040] In one specific embodiment, the connector 21 is provided with an avoidance notch, which can avoid interference with the components installed in the inner cavity and avoid affecting the installation of the components inside the housing.

[0041] See Figures 1-3 This utility model also provides an electricity meter, including the light guide column mounting structure described above.

[0042] Specifically, the housing 1 of the electricity meter is provided with two mounting posts 11. The outer walls of the two mounting posts 11 are connected by connecting blocks to improve the structural strength of the mounting posts 11. Each mounting post 11 is provided with a mounting hole 12. The light guide post 2 has two light guide indicator posts 22, and each light guide indicator post 22 is provided with a corresponding mounting hole 12.

[0043] See Figures 4-6 This utility model also provides a data acquisition terminal, including the light guide column mounting structure described above.

[0044] Specifically, the housing 1 of the acquisition terminal is provided with five mounting posts 11, and each mounting post 11 is provided with a mounting hole 12. The mounting hole 12 connects the inner cavity with the external environment. The light guide post 2 has five light guide indicator posts 22, and each light guide indicator post 22 is provided with a corresponding mounting hole 12.
