Description

Technical Field

[0001] This application relates to the technical field of electric energy metering, and particularly relates to an electric energy metering box for preventing wiring disconnection. Background Art

[0002] An electric energy metering box, in simple terms, is a box for installing electric meters. Its main features are that the electric energy meter, circuit breaker, wiring box of the meter box, and wires are all installed inside the box; various electric energy meters and power consumption circuits are assembled in an integrated closed box, which not only occupies less space and is easy to install and manage; the management responsibilities of power supply and consumption departments are clear, and there are strict intelligent anti-stealing electricity measures, so civil legal issues caused by stealing electricity can be effectively avoided; at the same time, it improves the meter reading efficiency of meter readers, reduces line losses, and meets the user's demand for electricity consumption and the requirement for power quality.

[0003] Referring to the Chinese patent application with the publication number CN212849478U, an electric energy metering box is disclosed. On the side of the sliding shielding mechanism close to the box door, locking mechanisms that can achieve locking and clamping are symmetrically arranged. When the device protects the box body, the push-pull handle is pulled to move the shielding L-shaped plate along the slide rail to the front surface of the box body. Such an electric energy metering box, under the combined action of the sliding shielding mechanism and the locking mechanism, realizes the protection and sealing of the box body when it is not necessary to open the box body, effectively prevents its surface from being corroded, and effectively realizes the protection of the outer wall of the metering box to prevent it from being corroded and damaged.

[0004] However, in the prior art, the connection between the connecting wire and the terminal in the electric energy metering box is usually fixed by screwing or bolts. When the staff repairs the equipment, the connecting wire will be frequently pulled, and there may be a phenomenon that the connecting wire becomes loose from the terminal, affecting the normal operation of the metering box and requiring the staff to repair it again, which is troublesome to operate. Therefore, we designed an electric energy metering box for preventing wiring disconnection.

[0005] Content of This Application

[0006] An electric energy metering box for preventing wiring disconnection provided by an embodiment of this application can give a light prompt when the staff pulls the connecting wire, avoiding the technical problem that the connecting wire falls off between the connecting wire and the terminal of the working device due to the staff pulling the connecting wire excessively.

[0007] An embodiment of this application provides an electric energy metering box for preventing wiring disconnection, including: a box body, a mounting mechanism, and a prompting mechanism.

An installation clamping plate 6 is installed on the working device 2, a terminal 5 connected to the connecting wire 10 is provided on the working device 2, and a through hole is opened at a position corresponding to the terminal 5 on the installation clamping plate 6;

[0038] With this setting, by sleeving the outer ring of the connecting wire 10 into the round hole of the cylindrical clamping block 11, turning the setscrew, fixing the clamping block 11 on the outer side wall of the connecting wire 10, connecting the connecting wire 10 to the terminal 5 on the working device 2, and then fixing the installation clamping plate 6 on the working device 2 to fix the connecting wire 10 on the working device 2, to prevent the connecting wire 10 from detaching from the working device 2.

[0039] Please refer to Figure 3, the installation mechanism further includes: a set of clamping blocks 8, a set of limiting guide grooves 9 and a set of guiding sliders 14. The clamping blocks 8 are arranged on the side of the installation card board 6 away from the working device 2. A set of clamping blocks 8 are symmetrically arranged on both sides of the through hole. A set of limiting guide grooves 9 are respectively opened on the mutually approaching surfaces of a set of clamping blocks 8;

[0040] A set of guiding sliders 14 are respectively symmetrically arranged on the outer side walls of the clamping blocks 11, and a set of guiding sliders 14 respectively slide in a set of limiting guide grooves 9. A round hole is opened on the clamping block 11, and the connecting wire 10 is threaded through the round hole. A set screw is threadedly connected to the clamping block 11, and an arc-shaped fixing piece is provided at one end of the set screw close to the connecting wire 10;

[0042] The effect of such a setting is that when the staff pulls the connecting wire 10, since a spring is provided between the clamping block 11 and the clamping block 8, it can be reset to a certain extent, avoiding the continuous disconnection of the connecting wire 10 from the wiring terminal 5.

[0043] Please refer to Figure 4 and Figure 5 , the prompting mechanism includes: a prompting lamp 12 and a set of inserting posts 13.

[0046] It can be seen from the above that the working principle of this application is as follows:

[0047] The two pins on the indicator light 12 are respectively connected to a set of studs 13, and the set of studs 13 are respectively inserted into the socket cylinders 7. Since the side walls of the set of socket cylinders 7 are provided with U-shaped conductive sheets, when the studs 13 are inserted at the bottom of the socket cylinders 7, the studs 13 do not contact the U-shaped conductive sheets, and the circuit is in an off state. At this time, the indicator light 12 is not lit;

[0048] When the staff repairs and inspects the metering box and excessively pulls the connecting wire 10, the stud 13 gradually moves away from the bottom of the socket cylinder 7. When the stud 13 contacts the U-shaped conductive sheet, the circuit is turned on. At this time, the indicator light 12 lights up, reminding the staff to gently pull the wire, and at the same time it is easy for the staff to quickly find the position where the connecting wire 10 is disconnected from the terminal 5 of the working device 2, facilitating the staff to quickly reconnect the connecting wire 10 to the terminal 5 of the working device 2.

[0049] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
