Detailed description of the invention
Below in conjunction with Figure of description, the concrete structure of electric energy meter inserting terminal in this utility model is done with explanation:
A kind of electric energy meter inserting terminal, as depicted in figs. 1 and 2, it plugging member 1 including there is hollow structure and tool
Having the contiguous block 2 of axial through bore 21, described plugging member 1 one end is to be suitable to and the Plug Division of electric current terminal hole grafting on electric energy meter
11, the other end is the tubulose wire connecting portion 12 being suitable to plug wire, and described tubulose wire connecting portion 12 is located in described axial through bore 21,
The sidewall of described axial through bore 21 is provided with the screw hole for arranging line ball screw；The outer end molding of described tubulose wire connecting portion 12
There is the location lug 121 extended radially outward, the outer face of described contiguous block 2 forms and is suitable to and described location lug
121 locating slots 24 coordinated.Using the structure in the present embodiment, inserting terminal is arranged in table torr afterwards by the location in table torr
Structure positions thus can not be axially moveable, and owing to location lug 121 is coordinated with locating slot 24, therefore, it is possible to prevent
Plugging member 1 relatively rotates with contiguous block 2, it is ensured that the line ball screw on contiguous block 2 and plugging member 1 (specifically tubulose wiring
Portion 12) tighten up a screw to bore a hole and align all the time such that it is able to improve wiring efficiency to a certain extent.Plugging member 1 in the present embodiment
Can be one-body molded parts, it is also possible to be the assembling parts assembled by least two parts.
Further, referring to Fig. 3 and Fig. 4, described axial through bore 21 sidewall forming the first perforation 22, described tubulose connects
On line portion 12 sidewall with described first perforation 22 corresponding positions form the second perforation 13, on described axial through bore 21 sidewall with
Described first perforation 22 relative positions form resigning hole 23, described tubulose wire connecting portion 12 form and described resigning hole 23
The positioning convex 14 coordinated.Use the structure in the present embodiment, tubulose wire connecting portion 12 is inserted the axial through bore 21 of contiguous block 2
In, by resigning hole 23 cooperation embedded with positioning convex 14 thus plugging member 1 is effectively connected with contiguous block 2, it is possible to enter one
Step avoids plugging member 1, with contiguous block 2, relative circumferentially rotating occurs, and moves axially, and resigning hole 23 is arranged on described second
