Abstract
A kind of integrated electric energy meter terminal assemblies of the utility model, comprise terminal base, forceful electric power terminal and light current terminal, described terminal base comprises the forceful electric power terminal base and light current terminal base that removably connect, described forceful electric power terminal embeds and is arranged in forceful electric power terminal base, described light current terminal embeds and is arranged in light current terminal base, the front end of described forceful electric power terminal stretches out from forceful electric power terminal base and is provided with the mutual inductor installed surface be connected with mutual inductor in its extension, and described forceful electric power terminal base is recessed to form step surface downwards in the part that stretches out of forceful electric power terminal.The utility model adopts removably to combine integrated by forceful electric power terminal base and light current terminal base, greatly reduces assembly difficulty; By arranging by the step surface to lower recess on forceful electric power terminal base, thus the installation region of mutual inductor and forceful electric power terminal can be held, and make the mutual inductor installed surface of forceful electric power terminal can completely from terminal base outwardly, make forceful electric power terminal can do the shortest, reach the object reduced costs.
Description
Technical field
The utility model is involved in ammeter technical field, particularly relates to a kind of integrated electric energy meter terminal assemblies.
Background technology
Existing electric energy meter generally has terminal assemblies, mutual inductor, relay, constructively separate between them, need when electric energy meter is installed to be arranged in electric meter box with securing member and web member by they are fastening, then with cable, each tie point is connected (being generally welding).(as shown in Figure 1), because the pad be electrically connected is many, the electric energy meter of this structure is installed very consuming time.
Terminal base is the vitals ensureing electric energy meter operating characteristic, and the supporter that it is made up of insulating material, is assembled with whole part line terminals of instrument, comprises forceful electric power electronics and light current terminal above it.At present, most of terminal base is split-type structural, and the connection in structure between multiple parts is fixed by securing member, requires high to fastening torsion, there is contact unreliable factor; For the ease of being linked and packed, the light current terminal that forceful electric power terminal can not be stacked in above blocks, and must be exposed at outside it, therefore terminal base longitudinal size requires longer, thus terminal base weight is strengthened, and holistic cost improves.
Therefore, be necessary to improve existing electric power meter end sub-component, to reduce assembly difficulty, save assembly cost and material cost.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of assembling simple, can save the integrated electric energy meter terminal assemblies of assembly cost and material cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of integrated electric energy meter terminal assemblies, comprise terminal base, forceful electric power terminal and light current terminal, described terminal base comprises the forceful electric power terminal base and light current terminal base that removably connect, described forceful electric power terminal embeds and is arranged in forceful electric power terminal base, described light current terminal embeds and is arranged in light current terminal base, the front end of described forceful electric power terminal stretches out from forceful electric power terminal base and is provided with the mutual inductor installed surface be connected with mutual inductor in its extension, and described forceful electric power terminal base is recessed to form step surface downwards in the part that stretches out of forceful electric power terminal.
Improve as one of the present utility model, described forceful electric power terminal rear end is provided with opening and inside is provided with for holding the cavity connecting wire, and the sidewall of described cavity is provided with trip bolt.
Concrete, described forceful electric power terminal base, being provided with seal groove away from an end face of trip bolt, is provided with sealing cord in described seal groove.
The utility model has the following advantages and beneficial effect compared to existing technology:
1, the utility model adopts removably to combine integrated by forceful electric power terminal base and light current terminal base, greatly reduces assembly difficulty; By arranging by the step surface to lower recess on forceful electric power terminal base, thus the installation region of mutual inductor and forceful electric power terminal can be held, and make the mutual inductor installed surface of forceful electric power terminal can completely from terminal base outwardly, make forceful electric power terminal can do the shortest, reach the object reduced costs.
2, adjacent attachment points of the present utility model can directly adopt trip bolt to lock, convenient and swift, reduces operation easier, thus enhances productivity.
Accompanying drawing explanation
Fig. 1 is terminal assemblies, mutual inductor and the relay installation diagram in electric meter box in prior art in electric energy meter.
Fig. 2 is the vertical view of the utility model integrated electric energy meter terminal assemblies.
Fig. 3 is the longitudinal sectional view of the utility model integrated electric energy meter terminal assemblies.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As Fig. 2, shown in Fig. 3, the present embodiment provides a kind of integrated electric energy meter terminal assemblies, comprise terminal base, forceful electric power terminal 1 and light current terminal 7, described terminal base comprises the forceful electric power terminal base 2 and light current terminal base 8 that removably connect, described forceful electric power terminal 1 embeds and is arranged in forceful electric power terminal base 2, described light current terminal 7 embeds and is arranged in light current terminal base 8, the front end of described forceful electric power terminal 1 stretches out from forceful electric power terminal base and is provided with the mutual inductor installed surface 3 be connected with mutual inductor in its extension, described forceful electric power terminal base 2 is recessed to form step surface downwards in the part that stretches out of forceful electric power terminal 1.By said structure, only forceful electric power terminal base 2 and its dismounting mode designed of light current terminal base need be combined and can complete during assembling; Owing to being provided with the step surface to lower recess on forceful electric power terminal base, thus the installation region of mutual inductor and forceful electric power terminal can be held, and make the mutual inductor installed surface of forceful electric power terminal can completely from terminal base outwardly, make forceful electric power terminal can do the shortest, reach the object reduced costs.
Described forceful electric power terminal 1 rear end is provided with opening and inside is provided with for holding the cavity 4 connecting wire, and the sidewall of described cavity 4 is provided with trip bolt 5.By said structure, the external power supply of access forceful electric power terminal can directly adopt trip bolt to connect, convenient and swift.
Described forceful electric power terminal base 2, being provided with seal groove away from an end face of trip bolt 5, is provided with sealing cord 6 in described seal groove.Seal groove is set by fitting surface between forceful electric power terminal base and drain pan, and by sealing cord dustproof and waterproof, meets the safety code requirements of electric energy meter.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
