[0042] Refer to Figure 1 , the present utility model provides a multifunctional electric quantity sensor, including: an installation part 100 and a connection part 200. An accommodation cavity for placing a plurality of measuring components 300 is provided in the installation part 100.

The connection part 200 is detachably arranged in the installation groove, and one side of the connection part 200 penetrates to the outside of the installation part 100. A plurality of interface ends 221 are detachably arranged on the side of the connection part 200 that penetrates to the outside of the installation part 100. The plurality of interface ends 221 are arranged in one-to-one correspondence with the plurality of measuring components 300, and each interface end 221 is electrically connected to the corresponding measuring component 300.

[0043] Specifically, refer to Figure 2, a receiving cavity is provided inside the installation part 100. The two ends of the receiving cavity extend along the length direction of the installation part 100, so that the accommodating space of the receiving cavity is large enough, and then multiple measuring components 300 can be placed in the receiving cavity to measure a variety of different data information of the electric quantity. The installation groove is opened on one side in the width direction of the installation part 100, and the two ends of the installation groove extend along the width direction of the installation part 100. Moreover, no groove wall is provided on the side of the installation groove close to the receiving cavity, so that the installation groove is communicated with the receiving cavity, facilitating the connection between the connection part 200 arranged in the installation groove and the multiple measuring components 300 arranged in the receiving cavity. One side of the connection part 200 extends along the height direction of the installation part 100, so that one side of the connection part 200 can be arranged in the installation groove, while the other side of the connection part 200 can penetrate through the side wall on one side in the height direction of the installation part 100 to the outside of the installation part 100. A plurality of interface ends 221 are arranged on the side of the connection part 200 far from the installation groove, that is, the side where the connection part 200 penetrates to the outside of the installation part 100. The plurality of interface ends 221 are fixed through the connection part 200. Moreover, the plurality of interface ends 221 are arranged in one-to-one correspondence with the plurality of measuring components 300. The input ends of the plurality of interface ends 221 are respectively electrically connected to the output ends of the corresponding measuring components 300, and the output ends of the interface ends 221 can be electrically connected to an external information receiving device, so that the measurement results of the data information of the electric quantity by the plurality of measuring components 300 can be respectively transmitted to the external information receiving device through the plurality of corresponding interface ends 221, facilitating the staff to quickly obtain various different data information about the electric quantity and greatly improving the efficiency of measuring the electric quantity information. Among them, the installation part 100 and the connection part 200 are detachably connected, so that they can be quickly replaced when the installation part 100 or the connection part 200 is damaged. The plurality of interface ends 221 and the connection part 200 are also detachably connected, so that any interface end 221 can be quickly replaced when it is damaged, with simple and convenient operation and improved installation efficiency.

[0044] It should be noted that the specific specification parameters between the plurality of interface ends 221 are not the same. Since different measuring components 300 need to be connected to interface ends 221 with different specification parameters, the specification parameters of each interface end 221 are determined according to the requirements of the corresponding measuring component 300.

[0045] In some specific embodiments of the present invention, refer to Figure 1, the installation part 100 includes: an upper shell 110 and a lower shell 120. The upper shell 110 and the lower shell 120 are arranged opposite to each other up and down, and are snap-connected between the upper shell 110 and the lower shell 120. Among them, the inner walls of the upper shell 110 and the lower shell 120 enclose a receiving cavity. An installation opening 1121 is provided on one side in the body width direction of the upper shell 110, and both ends of the installation opening 1121 extend along the body length direction of the upper shell 110. An installation groove can be formed through the installation opening 1121 and the space in the lower shell 120, and then the connection part 200 can be installed by inserting the connection part 200 into the installation groove. After the connection part 200 is inserted into the installation groove, the installation position of the connection part 200 can be fixed and restricted by the inner wall of the installation opening 1121. The installation is convenient, the operation is simple and convenient, the installation efficiency is improved, and the replacement can be quickly completed when the connection part 200 is damaged.

[0046] Further, referring to Figure 3 , a stepped structure is provided on one side in the body width direction of the upper shell 110, so that a first covering surface 111 and a second covering surface 112 can be formed on the upper shell 110. Among them, the area of the first covering surface 111 is larger and the horizontal height of the first covering surface 111 is higher than the horizontal height of the second covering surface 112. Thus, a receiving cavity capable of placing a plurality of measuring components 300 is enclosed by the first covering surface 111 of the upper shell 110 and the inner wall of the lower shell 120, and a space capable of forming an installation groove is enclosed by the second covering surface 112 of the upper shell 110 and the inner wall of the lower shell 120. The installation opening 1121 is opened on the second covering surface 112, so that the height in the body height direction of the installation groove is less than the height in the body height direction of the receiving cavity, which is convenient for the interface end 221 on the connection part 200 to be exposed outside the installation groove after the connection part 200 is arranged in the installation groove, so as to be connected to an external information receiving device. Moreover, the first covering surface 111 and the second covering surface 112 with inconsistent horizontal heights are convenient for distinguishing the dividing line between the installation groove and the receiving cavity, so that the setting space of the installation groove can be avoided when placing a plurality of measuring components 300, and the installation accuracy of the device is improved. At the same time, the installation groove and the receiving cavity can also be directly communicated, which is convenient for processing.

[0047] Further, the horizontal height of the end surface on the side of the connection part 200 exposed outside the installation groove is less than the horizontal height of the first covering surface 111, so that the upper shell 110 can protect the interface end 221 of the connection part 200 and avoid damage caused by an external object hitting the connection end of the connection part 200.

[0048] In some specific embodiments of the present invention, referring to Figure 4, the connecting portion 200 includes: a mounting base 210 and a connecting base 220. The mounting base 210 is detachably disposed in the mounting groove, and the mounting base 210 is sealingly connected to the mounting opening 1121. A passageway for the pipeline to pass through is provided in the mounting base 210. The connecting base 220 is detachably disposed on the side of the mounting base 210 away from the lower housing 120. A plurality of interface ends 221 are disposed on the connecting base 220 and communicate with the passageway, so that the pipeline can connect the interface ends 221 and the measuring component 300.

[0049] Specifically, the mounting base 210 passes through the mounting opening 1121 and is inserted into the mounting groove. The inner wall of the mounting opening 1121 can fix and limit the mounting base 210, thereby ensuring the mounting stability. The connecting base 220 is detachably disposed on the side of the mounting base 210 that passes through the mounting groove to the outside, so that a plurality of interface ends 221 disposed on the connecting base 220 are also disposed outside the mounting groove. Thus, under the limiting action of the mounting opening 1121 on the mounting base 210, the mounting stability of the interface ends 221 can be ensured, and through the detachable connection relationship between the connecting base 220 and the mounting base 210, it is convenient to replace the interface ends 221, so that the interface ends 221 can be replaced when the interface ends 221 are damaged or the specification parameters of the interface ends 221 need to be replaced, which is convenient for installation and disassembly. Among them, a passageway is provided in the mounting base 210, and a pipeline is passed through the passageway. One end of the pipeline is connected to the input ends of a plurality of interface ends 221 of the connecting base 220 detachably disposed on the mounting base 210, and the other end of the pipeline passes through the passageway into the accommodating cavity and is connected to the output ends of a plurality of measuring components 300 in one-to-one correspondence, so as to facilitate the connection of a plurality of interface ends 221 and a plurality of measuring components 300 respectively.

[0050] In some specific embodiments of the present invention, refer to Figure 4 , the mounting base 210 is connected to the lower housing 120 by plug-in connection.

[0051] Specifically, a jack 211 is provided on the bottom surface of the mounting base 210, that is, on the side of the mounting base 210 close to the inner bottom wall of the lower housing 120. A plug post 121 is provided on the inner bottom wall of the lower housing 120 opposite to the jack 211. The plug post 121 and the jack 211 are mutually adapted. During the process of placing the mounting base 210 in the mounting groove, the plug post 121 and the jack 211 can be plugged and connected, so that the mounting base 210 and the lower housing 120 are plugged, making the installation of the mounting base 210 more stable.

[0052] Further, there are two jacks 211, and the two jacks 211 are symmetrically opened on both sides in the length direction of the bottom surface of the mounting base 210. There are two plug posts 121, and the two plug posts 121 are arranged in one-to-one correspondence with the two jacks 211, so as to further improve the mounting stability of the mounting base 210.

[0053] Alternatively, on the side of the mounting base 210 close to the inner bottom wall of the lower housing 120, i.e., on the bottom surface of the mounting base 210, there is a jack 211, and internal threads are provided on the inner wall of the jack 211. Opposite to the jack 211 on the inner bottom wall of the lower housing 120, there is a plug post 121. The plug post 121 is a hollow structure, and internal threads are also provided on the inner wall of the plug post 121. The internal threads of the jack 211 and the internal threads of the plug post 121 are coordinated so that the jack 211 and the plug post 121 can be threadedly connected by bolts, increasing the mounting firmness of the mounting base 210.

[0054] Furthermore, a through pipe 212 is provided at the bottom of the mounting base 210, and the inner wall of the through pipe 212 forms a through passage. The through pipe 212 is inserted into the mounting base 210. One end of the through pipe 212 can communicate with the interface end 221 of the connecting seat 220, and the other end extends to the outside of the mounting base 210, so that the pipeline can pass through the through pipe 212 to connect the interface end 221 with the measuring component 300.

[0055] Furthermore, the through pipe 212 is inserted into the bottom surface of the mounting base 210. One end of the through pipe 212 extends in the body height direction of the mounting base 210 towards the connecting seat 220, and the other end extends in the body height direction of the mounting base 210 towards the inner bottom wall of the lower housing 120, which can reduce the occupied space of the mounting base 210 in the upper housing 110 and the lower housing 120 after installation.

[0056] It should be noted that after the jack 211 and the plug post 121 are plugged and connected, there is a gap between the bottom surface of the mounting base 210 and the inner bottom wall of the lower housing 120, so that there is also a gap between the end of the through pipe 212 close to the inner bottom wall of the lower housing 120 and the inner bottom wall of the lower housing 120, so that the pipeline can pass through.

[0057] In some specific embodiments of the present utility model, referring to Figure 6 , a sealing ring 2151 is provided between the side wall of the mounting base 210 and the inner wall of the mounting opening 1121. The sealing ring 2151 is sleeved on the side wall of the mounting base 210. The gap between the mounting base 210 and the mounting opening 1121 can be blocked by the sealing ring 2151. While preventing external impurities from entering the upper housing 110 and the lower housing 120 through the gap, it can also prevent the mounting base 210 inserted into the mounting groove from shaking due to the gap, improving the mounting sealing performance and stability of the mounting base 210. At the same time, under the action of the sealing ring 2151, the friction force between the mounting base 210 and the mounting opening 1121 can be increased, thereby preventing the mounting base 210 from easily coming out of the mounting groove and improving the mounting firmness of the mounting base 210.

[0058] Furthermore, referring to Figure 5, a sealing groove 215 is formed around the side wall of the mounting base 210 and is disposed opposite to the inner wall of the mounting opening 1121. The sealing ring 2151 is sleeved in the sealing groove 215, which is convenient for installing the sealing ring 2151 and preventing the sealing ring 2151 from slipping out between the mounting base 210 and the mounting opening 1121.

[0059] In some specific embodiments of the present invention, referring to Figure 4 , a plugging groove 213 is formed on the top surface of the mounting base 210, which is the side away from the lower housing 120. One end of the through pipe 212 close to the plugging groove 213 is communicated with the bottom of the plugging groove 213, so that the plugging groove 213 is communicated with the through passage. The connecting seat 220 can be inserted into the plugging groove 213. This not only facilitates the connection between the interface end 221 of the connecting seat 220 and the pipeline passing through the through passage communicated with the bottom of the plugging groove 213, but also enables the insertion between the mounting base 210 and the connecting seat 220 through the plugging groove 213, which is convenient for installation.

[0060] Furthermore, on both sides of the connecting seat 220 in the body width direction, connecting blocks 223 are symmetrically arranged, and bolts are provided on the connecting blocks 223 opposite to the mounting base 210. Connecting holes 214 are respectively formed on both sides of the top surface of the mounting base 210 in the body length direction opposite to the two bolts, so that the connecting blocks 223 and the connecting holes 214 can be connected by bolts, thereby improving the connection firmness between the mounting base 210 and the connecting seat 220.

[0061] In some specific embodiments of the present invention, referring to Figure 4 , a plurality of sockets 222 are arranged on the side of the connecting seat 220 close to the mounting base 210. The plurality of sockets 222 are respectively connected to the plurality of interface ends 221 in one-to-one correspondence, and the plurality of sockets 222 are adapted to the plugging groove 213.

[0062] Specifically, the plurality of interface ends 221 are uniformly arranged on the side of the connecting seat 220 away from the mounting base 210, and are uniformly arranged along the body length direction of the connecting seat 220. The plurality of sockets 222 are uniformly arranged on the side of the connecting seat 220 close to the mounting base 210, and are uniformly arranged along the body length direction of the connecting seat 220. The plurality of sockets 222 are respectively connected to the plurality of interface ends 221 in one-to-one correspondence. Both ends of the plugging groove 213 extend along the body length direction of the connecting seat 220, so that the plurality of uniformly arranged sockets 222 can be adapted to the plugging groove 213, and the plugging connection between the connecting seat 220 and the mounting base 210 is completed by inserting the plurality of sockets 222 into the plugging groove 213. Among them, the plurality of interface ends 221 can be respectively connected to the pipelines through the plurality of sockets 222.

[0063] Furthermore, referring to Figure 4, there are multiple through pipes 212, and pipelines are arranged in each through pipe 212. The multiple through pipes 212 are arranged in one-to-one correspondence with the multiple sockets 222, so that any interface end 221 can be connected to the measuring component 300 corresponding to the specification of the interface end 221 through the socket 222 corresponding to the interface end 221 and the through pipe 212 corresponding to the socket 222 in sequence. Thus, various different data information about the electric quantity can be obtained quickly, and the efficiency of measuring the electric quantity information is greatly improved.

The clamping arm 2242 is arranged at one end of the connecting arm 2241 close to the mounting seat 210, and the clamping arm is connected to the connecting arm 2241 at an included angle. Refer to Figure 5 , a convex structure is arranged outside the side wall of the mounting seat 210, so that a clamping groove 216 can be formed on the side wall of the mounting seat 210. When the socket 222 is inserted into the insertion slot 213, the end of the clamping arm 2242 far from the connecting arm 2241 can be clamped into the clamping groove 216, thereby realizing the clamping of the connection seat 220 and the mounting seat 210.

[0066] Furthermore, there are multiple clamping components 224, and the multiple clamping components 224 are evenly arranged along the body length direction of the connection seat 220, which can further improve the connection stability between the mounting seat 210 and the connection seat 220.
