[0030] In addition, the terms "first", "second", and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0031] As Figures 1-2As shown in the drawings, the embodiment provides a wire fixing device, which comprises an insulating base plate 1, a magnetic block 4 embedded in the back of the insulating base plate 1, the magnetic block 4 being arranged at the center of the back of the insulating base plate 1 and the magnetic surface being flush with the back of the base plate; the front of the insulating base plate 1 has five test wire fixing clamps 2 arranged at equal intervals along the length direction of the insulating base plate 1; each test wire fixing clamp 2 is wrapped with an insulating rubber layer outside, and has a flexible metal buckle inside for clamping and fixing the test wire joint, the metal buckle having a clamping flexible slit at the top end; the top of the insulating base plate 1 is provided with a clamping groove 3 for connecting with a hook 6, and each clamping groove 3 is provided with two hooks 6; the bottom and side of the insulating base plate 1 are provided with magnetic strips 5.

[0032] As shown in the drawings, Figures 2-3 The embodiment is the same as the above embodiment, except that the top or bottom of the insulating base plate 1 is provided with a transversely extending clamping groove 3, and the base 62 of the hook 6 is adapted to the clamping groove 3. The hook 6 comprises a front hook, a base 62 and a chain 61 connecting the front hook and the base 62, the chain 61 being formed by hooking a plurality of chain links, and the chain link having a break 611 for disassembling a single chain link. Specifically, the chain link has eight chain links. The clamping groove 3 is a T-shaped groove transversely penetrating the front and back of the base plate, and the base 62 of the hook 6 is a T-shaped sliding block of corresponding shape. The T-shaped sliding block can be connected to the T-shaped groove in two ways: one is to vertically insert from the slot opening of the T-shaped groove and rotate by an angle, so that the flange of the T-shaped sliding block interferes with the channel of the T-shaped groove to realize locking; the other is to slide into the groove from any transverse end opening of the T-shaped groove. By rotating the base 62, the T-shaped sliding block can be converted between the locked state and the released state, so as to realize the quick connection of the hook 6 and the fixing device. The wire fixing device can be fixed at places where magnetic attraction cannot be achieved by the hook 6, thereby increasing the use scenarios.

[0033] As shown in the drawings, Figure 4 A test wire fixing device is provided, which has two wire fixing devices in the above embodiments, the opposite contact surfaces of the two wire fixing devices being provided with magnetic strips 5, and the adjacent placement being attracted to each other by the magnetic strips 5; the clamping grooves 3 are connected through at the upper and lower end surfaces of the wire fixing device, specifically, the clamping groove 3a of the first wire fixing device on the left is aligned with the clamping groove 3b of the second wire fixing device on the right; and the magnetic blocks 4 on the back form a uniformly distributed magnetic point array.

[0034] As shown in the drawings, Figure 5As shown, a test wire fixing device is provided, comprising four wire fixing devices as described in the above embodiments connected together to form a whole. Each of the four wire fixing devices occupies one corner, forming a grid-like arrangement. Each wire fixing device has magnetic strips 5 on its two sides near the center, with the corresponding magnetic strips 5 adsorbing and connecting to each other. The device can be disassembled into four independent wire fixing devices. Specifically, the magnetic strips 5 are located on the left and bottom sides of the upper left first wire fixing device, the right and bottom sides of the upper right second wire fixing device, the left and top sides of the lower left third wire fixing device, and the right and top sides of the lower right fourth wire fixing device. The slots 3 are connected and intersected on the upper and lower ends of the wire fixing device. Specifically, the upper left first wire fixing slot 3a and the upper right second wire fixing slot 3b are aligned, and the lower left third wire fixing slot 3c and the lower right fourth wire fixing slot 3d are aligned. The magnetic blocks 4 on the back together form a uniformly distributed array of magnetic attraction points.

[0035] like Figure 6 As shown, the test lead fixing clips 2 are arranged in multiple rows on the front. Each test lead fixing clip 2 includes a voltage test lead fixing clip 22 and a current test lead fixing clip 21. The voltage test lead fixing clips 22 are distributed on one or more insulating base plates 1, and the current test lead fixing clips 21 are distributed on one or more different insulating base plates 1, allowing for flexible combination and use according to site conditions. Specifically, there are ten voltage test lead fixing clips 22 in total, forming ten evenly arranged groups of test lead fixing clips 2. In one arrangement, voltage test lead fixing clips 22 are installed on two insulating base plates 1, and current test lead fixing clips 21 are installed on the other two; or, three current test lead fixing clips 21 and two voltage test lead fixing clips 22 are installed on each of two insulating base plates 1, and two current test lead fixing clips 21 and three voltage test lead fixing clips 22 are installed on each of the other two insulating base plates 1. This partitioned wiring arrangement makes wiring operations more standardized.

[0036] The device can be disassembled into four independent wiring holders, each of which can be used independently with identical functions. If there is no suitable location to place the four-piece assembly, it can be disassembled into two halves for hanging, or the four individual units can be fixed in different positions on the control panel for convenient temporary fixing of meter wiring in different locations. When there are many test wires that need to be fixed, and the five test wire fixing clamps are insufficient, multiple separate parts can be combined.

[0037] Working principle: the device fixed mode: the insulating rubber bottom plate is laid in the screen cabinet metal part, if the working environment has no magnetic attraction part, the device can be fixed in the place where the magnetic attraction is not available through the hook 6, the chain 61 is detachable and can be flexibly adjusted in length according to the site; during the process of instrument wiring, the test line head is clamped on the test line fixing clamp 2 in turn and phase by phase, during the process of calibration loop wiring, the calibration loop wiring is removed in turn and phase by phase, and the test line is fixed on the test line fixing clamp 2; after the work is completed, the whole is stored or each part is put into a small tool bag for unified arrangement and storage.

[0038] The device can not only be applied to the on-line calibration of the gateway electric energy meter, but also be applied to other working surfaces needing to use the test line.

[0039] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
