[0023] The following further describes the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0024] As Figures 1 - 3 shown, the integrated monitoring device of the present utility model includes:

[0025] A housing 1, the housing 1 is a hollow structure, and the housing 1 is provided with an acquisition through hole 121, a cold pressure terminal wire reserved port, a reserved port 111 for wiring terminals and a reserved port 112 for display. The acquisition through hole 121 is for monitoring cables to pass through and is separated from the inner cavity of the housing 1. The cold pressure terminal wire reserved port, the reserved port 111 for wiring terminals and the reserved port 112 for display are all separated from the inner cavity of the housing 1;

[0026] Monitoring component 2, the monitoring component 2 includes a monitoring circuit board, a monitoring terminal block, a signal temperature acquisition cold-press terminal wire 25, and a display module interface 26. The monitoring circuit board is arranged inside the housing 1. The monitoring terminal block and the signal temperature acquisition cold-press terminal wire 25 are both electrically connected to the monitoring circuit board and respectively pass through the inner sides of the cold-press terminal wire reserved openings and the inner side of the terminal block reserved opening 111. The display module interface 26 passes through the inner side of the display reserved opening 112 and is electrically connected to the monitoring circuit board. The display module interface 26 is used to connect to the human-machine interface;

[0027] Signal acquisition component 3, the signal acquisition component 3 is arranged adjacent to the monitoring component 2. The signal acquisition component 3 includes a signal acquisition coil 31 electrically connected to the monitoring circuit board. The acquisition through-holes 121 are respectively located inside the signal acquisition coil 31.

[0028] In this monitoring device, the monitoring component 2 and the signal acquisition component 3 are arranged adjacent to each other on the housing 1. On the one hand, the signal acquisition part and the signal monitoring part are integrated together. On the other hand, the compactness of the internal structure of the device is ensured, the integration degree is improved, and an integrated design is formed. In this way, through the integrated design, the entire power distribution monitoring system is made more simple and neat, thus facilitating the installation, inspection, and maintenance work of the monitoring device by the staff. On the basis of saving auxiliary materials, the labor cost is reduced, the occupied space is reduced, and thus the cost investment can be reduced.

[0029] In the housing 1 of the monitoring device of the present utility model, specifically three acquisition through-holes 121 are provided. The acquisition through-holes 121 are used for the cables of the power distribution system to pass through. And the acquisition through-holes 121 are located inside the signal acquisition coil 31, so that the cables pass through the inside of the signal acquisition coil 31 at the same time, facilitating the acquisition of the signal parameters of the power distribution system and transmitting the signal parameters to the monitoring circuit board. The monitoring circuit board is connected with a monitoring terminal block, and the monitoring terminal block is adapted to the terminal block reserved opening 111, so that when the device is assembled, the monitoring terminal block is located outside the housing 1, thus facilitating external wiring. And a display reserved opening 112 is also provided on the housing 1. The display reserved opening 112 is adapted to the display module interface 26 fixed on the monitoring circuit board and allows the display module interface 26 to be adapted, facilitating the display module interface 26 to access the human-machine interface to observe the relevant parameters of the power distribution system. In the present utility model, the display module interface 26 is selected as the RJ11 display module interface 26.

[0030] There are also three reserved cold-pressed terminal wire openings provided on the outer shell 1, through which three signal temperature acquisition cold-pressed terminal wires 25 pass respectively. The three signal temperature acquisition cold-pressed terminal wires 25 are electrically connected to the monitoring circuit board. The signal temperature acquisition cold-pressed terminal wires 25 are mainly used for the connection of various electrical circuits, including power, communication, control, etc. By mechanically pressing the guide on the terminal, a reliable connection between wires or between a wire and a device can be achieved. Compared with traditional connection methods such as welding and screw fixation, the signal temperature acquisition cold-pressed terminal wires 25 have a faster and simpler installation process, and at the same time can ensure better electrical stability and mechanical strength.

[0031] A further improvement is that the outer shell 1 includes a monitoring housing 11 and a signal acquisition housing 12 that are detachably connected. By means of detachable connection, it is convenient for the monitoring housing 11 and the signal acquisition housing 12 to be connected and assembled multiple times, facilitating the maintenance of the device.

[0032] A further improvement is that the monitoring housing 11 and the signal acquisition housing 12 are snap-fitted. By using the snap-fitting method, it is convenient for the monitoring housing 11 and the signal acquisition housing 12 to be quickly detachably connected.

[0033] Specifically, there are symmetrically distributed snap-fit parts between the monitoring housing 11 and the signal acquisition housing 12. The snap-fit parts include a snap 122 and a bayonet 113 that are snap-fitted; among the monitoring housing 11 and the signal acquisition housing 12, one is provided with a positioning convex frame 123, and the other is inserted and matched with the positioning convex frame 123, and the insertion direction is parallel to the distribution direction of the monitoring housing 11 and the signal acquisition housing 12.

[0034] More specifically, both the monitoring housing 11 and the signal acquisition housing 12 are in the shape of a cuboid. The length of the monitoring housing 11 is less than the length of the signal acquisition housing 12. The width of the monitoring housing 11 is the same as the width of the signal acquisition housing 12. The height of the monitoring housing 11 is less than the height of the signal acquisition housing 12. The length direction of the monitoring housing 11 is parallel to the length direction of the signal acquisition housing 12, and the height directions are the same. The monitoring housing 11 is centrally arranged above the signal acquisition housing 12.

[0035] The positioning convex frame 123 is arranged on the signal acquisition housing 12. The monitoring housing 11 is a monitoring housing cover facing the signal acquisition housing 12. The circumferential inner wall of the monitoring housing cover is hermetically connected to the circumferential outer edge of the positioning convex frame 123. There are four bayonets 113, which are respectively adjacent to the four corners at the bottom of the monitoring housing cover. Correspondingly, there are four buckles 122, which are located adjacent to the dead corners of the positioning convex frame 123. During assembly, the bottom of the monitoring housing cover is sleeved outside the positioning convex frame 123, so that while the circumferential outer edge of the positioning convex frame 123 is hermetically connected to the circumferential inner wall of the monitoring housing cover, the buckle 122 is clamped into the bayonet 113, thus completing the rapid assembly of the monitoring housing 11 and the signal acquisition housing 12. Since there are four bayonets 113 and four buckles 122, and they are symmetrically distributed on the outer shell 1, it ensures that the connection parts between the monitoring housing 11 and the signal acquisition housing 12 are evenly stressed, thereby improving the connection strength between the monitoring housing 11 and the signal acquisition housing 12.

[0036] A further improvement is that the signal acquisition housing 12 is also provided with a signal acquisition reserved hole 124 inside the positioning convex frame 123. The signal acquisition reserved hole 124 is used for the connection of the signal acquisition coil 31 and the monitoring circuit board. Through the signal acquisition reserved hole 124, it is convenient for the signal cable to pass through, and the two ends are respectively connected to the signal acquisition coil 31 and the monitoring circuit board, so as to realize the transmission of the power signal data collected by the signal acquisition coil 31 to the monitoring circuit board.

[0037] A further improvement is that the wiring terminal reserved port 111 is arranged on the side wall of the monitoring housing cover. The wiring terminal reserved port 111 extends to the bottom of the monitoring housing cover and is adapted to the wiring terminal. The monitoring circuit board includes a fixedly connected monitoring main circuit board 21 and a monitoring expansion circuit board 22. The monitoring wiring terminals include a main circuit board wiring terminal 23 and an expansion board wiring terminal 24 respectively connected to the monitoring main circuit board 21 and the monitoring expansion circuit board 22.

[0038] Specifically, in the present utility model, there are two wiring terminal reserved ports 111, which are respectively located at the bottom positions of both ends of the monitoring housing cover, and are respectively adapted to the main circuit board wiring terminal 23 and the expansion board wiring terminal 24, so as to facilitate the fixing of the monitoring main circuit board 21 and the monitoring expansion circuit board 22 inside the monitoring housing 11. The monitoring main circuit board 21 and the monitoring expansion circuit board 22 are welded together by pins, and the RJ11 display module interface 26 is fixed on the monitoring main circuit board 21.

[0039] In addition, three first terminal wire reserved holes 114 distributed along the length direction of the monitoring housing 11 are provided at the bottom of the monitoring housing 11, and three second terminal wire reserved holes 127 distributed along the length direction of the signal acquisition housing 12 are provided at the top of the signal acquisition housing 12. After the monitoring housing 11 and the signal acquisition housing 12 are snap-connected, the three first terminal wire reserved holes 114 communicate with the three second terminal wire reserved holes 127 in one-to-one correspondence, forming three cold-pressed terminal wire reserved openings for the three signal temperature acquisition cold-pressed terminal wires 25 to pass through respectively.

[0040] A further improvement is that the signal acquisition housing 12 includes a signal acquisition housing cover 125 and a signal acquisition cover plate 126 for covering the signal acquisition housing cover 125, and the signal acquisition coil 31 is clamped between the signal acquisition housing cover 125 and the signal acquisition cover plate 126. With the above structure, it is convenient to assemble the signal acquisition coil 31 into the signal acquisition housing 12, and the signal acquisition cover plate 126 can be fixed to the signal acquisition housing 12 by ultrasonic welding.

[0041] A further improvement is that it further includes a lens 4 for covering the display module interface 26 and the human-machine interaction interface. Specifically, the lens 4 is fixed to the side of the monitoring housing 11 away from the signal acquisition housing 12. By covering the display module interface 26 and the human-machine interaction interface with the lens 4, the protection effect on the display module interface 26 and the human-machine interaction interface is achieved.

[0042] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
