[0026] Example

[0027] This embodiment provides a tooling device for assembling a power meter terminal box. At least one current transformer 11 is connected to the terminal box 1. The current transformer 11 and the terminal box 1 are fastened together with screws. The tooling device includes a body 2 and a positioning structure 3 formed on the body 2. The positioning structure 3 has a clearance space to avoid the terminal box 1 and / or the current transformer 11.

[0028] The specific improvements mentioned above are as follows: Figure 1 and Figure 2As shown, when the current transformer 11 needs to be installed in the terminal box 1, simply place the terminal box 1 into the clearance space of the positioning structure 3, and then place the current transformer 11 into the clearance space of the positioning structure 3. By setting the clearance space, the current transformer 11 and the terminal box 1 can be embedded in the clearance space of the positioning structure 3. In this way, when screwing the connection between the current transformer 11 and the terminal box 1, there will be no slippage or stripping of the threads due to the shaking of the current transformer 11 or the terminal box 1.

[0029] Based on the above embodiments: the positioning structure 3 includes a first positioning groove 31 for positioning the end button box 1 and a second positioning groove 32 for positioning the current transformer 11.

[0030] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, the positioning structure 3 consists of a first positioning groove 31 for fixing the end box 1 and a second positioning groove 32 for fixing the current transformer 11. When fixing the end box 1 and the current transformer 11, the end box 1 must first be placed in the first positioning groove 31, and then the current transformer 11 must be placed in the second positioning groove 32 to ensure the stability of the end box 1 and the current transformer 11. Finally, screws are driven into the connection between the end box 1 and the current transformer 11. Due to the setting of the first positioning groove 31 and the second positioning groove 32, the operator can ensure the stability of the end box 1 and the current transformer 11 when driving screws.

[0031] Based on the above embodiments: a positioning plate 4 is provided on the upper end face of the body 2, the positioning plate 4 is detachably connected to the body 2, and the second positioning groove 32 is formed on the positioning plate 4.

[0032] The specific improvements mentioned above are as follows: Figures 2-4 As shown, a positioning plate 4 is provided on the main body 2. The positioning plate 4 is fastened to the main body 2 with screws. Since the position of the current transformer 11 of different models of energy meters varies, in order to adapt to different models of current transformer 11, the corresponding positioning plate 4 can be selected and installed on the top of the main body 2 according to the specific situation during installation, so as to effectively adapt to different models of energy meters.

[0033] Based on the above embodiments: the main body 2 is provided with positioning blocks 21 for positioning both sides of the end button box 1, and the positioning blocks 21 are provided with clearance space for avoiding the end button box 1.

[0034] The specific improvements mentioned above are as follows: Figure 1As shown, the main body 2 can hold 2-3 end-cap boxes 1 and current transformers 11. To ensure that the end-cap boxes 1 can be fixed around the perimeter, positioning blocks 21 are provided on the main body 2. The positioning blocks 21 are provided with clearance space to avoid the end-cap boxes 1. Thus, when the end-cap boxes 1 are placed in the first placement slot, the cooperation between the first positioning slot 31 and the positioning blocks 21 on both sides can effectively position the end-cap boxes 1 during the operator's screw-in process.

[0035] Based on the above embodiments: the terminal box 1 includes a first connecting shell 12 for connecting signal terminals, the first positioning groove 31 is provided with a space for the first connecting shell 12 to be inserted, and the first positioning groove 31 is also provided with an extension post 5 that abuts against the bottom of the first connecting shell 12.

[0036] Based on the above embodiments: the end box 1 includes a second connecting shell 13 for connecting current terminals, and the lower end face of the second connecting shell 13 abuts against the upper end face of the body 2.

[0037] The specific improvements mentioned above are as follows: Figures 3-5 As shown, the end button box 1 includes a first connecting shell 12 and a second connecting shell 13. Since the structures of the first connecting shell 12 and the second connecting shell 13 are not on the same plane, in order to avoid the first connecting shell 12 and thus ensure that the end button box 1 can be placed in the first positioning groove 31 without shaking, an extension post 5 is provided in the first positioning groove 31. Through the setting of the extension post 5, it can abut against the lower end face of the first connecting shell 12, and the lower end face of the second connecting shell 13 abuts against the upper end face of the body 2. In this way, when the end button box 1 is placed in the first positioning groove 31, it will not shake.

[0038] Based on the above embodiment: a partition rib 6 is provided between adjacent second positioning grooves 32.

[0039] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, by setting the dividing rib 6, the positioning groove can be divided into 3 areas, so as to better fit with the current transformer 11 and prevent the current transformer 11 from moving.

[0040] Based on the above embodiments: the positioning block 21 is arranged in an "L" shape.

[0041] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, the positioning block 21 is set in an "L" shape, which can better wrap the edge of the end button box 1 and prevent it from shaking.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
