Description
Technical field
The utility model relates to electric instrument part field, specifically refers to a kind of pcb board stationary installation of electric energy meter.
Background technology
Ansi standard electric energy meter generally comprises the pcb board summation current transformer, function terminal etc. of power supply, at present, electric energy meter pcb board fixed form is mainly increase by 4 pillar location pcb boards in ammeter drain pan and uses screw lock again, and ammeter function terminal and PCB connected mode are mainly wire bonds.This assembling mode, increases by 4 pillars in drain pan and takes up room greatly, be unfavorable for that pcb board designs, and due in the middle part of pcb board without any support, there is bad mechanical strength, be electrically connected the technical matterss such as unreliable; Pillar needs could lock pcb board with screw fit, adds manpower and automation equipment cost, reprocesses also inconvenience; Function terminal welds with pcb board leads for connecting can only manual work, and efficiency is too low, and wire also will be riveted together with function terminal in advance, adds Material Cost.
Mandate publication number is that the Chinese utility model patent of 202757969U discloses a kind of electric energy meter pcb board fixed sturcture, comprises the housing of electric energy meter; Housing is provided with the first column group of more than a group and the second column group of more than a group, and one group of first column group comprises two the first columns, and one group of second column group comprises second column of more than two; First column is provided with the first draw-in groove, and each first draw-in groove organized on the first column in the first column group is oppositely arranged; Second column is provided with the second draw-in groove, and each second draw-in groove organized on the second column in the second column group is arranged with equidirectional.After adopting above-mentioned this assembling mode, although assembling is easier, can improve the efficiency of fixing pcb board, still taking up room of the many groups column in drain pan is large; Because the interface of the pillar in this structure and pcb board is little, stress point is concentrated, and needs to use high quality material injection moulding to complete, and product uses the later stage, may occur material cracks, hold in the mouth and sting the phenomenons such as loosening; And function terminal and pcb board still can only use wire bonds, complicated operation, production cost is high.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of processing assembling simple, the pcb board stationary installation of the electric energy meter that production cost is low.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pcb board stationary installation of electric energy meter, comprise pcb board, drain pan and function terminal, it is characterized in that: one end of described drain pan is provided with the terminal base for being installed in function terminal, other end sidewall is provided with the drain pan draw-in groove of the anterior close-fitting clamping with pcb board, described pcb board afterbody is provided with several fluting and pilot holes, described terminal base is provided with and corresponding limit rib and the spacing pillar corresponding with pilot hole of slotting, described terminal base and pcb board all have through hole, described pcb board penetrates described pcb board successively by screw, through hole on terminal base and function terminal are assembled together and circuit board and function terminal are formed and be electrically connected.
One as such scheme is preferred, and described drain pan draw-in groove is provided with 2, is separately positioned on 2 top corner edge places of both sides, drain pan end.
Concrete, described function terminal embeds and is connected on terminal base.
The utility model has the following advantages and beneficial effect compared to existing technology:
The utility model, owing to decreasing drain pan pcb board location pillar and eliminating the wire that function terminal is connected with pcb board, when profile size constancy, adds inner space, is convenient to pcb board design; Function terminal and pcb board connected mode change screw into by wire, are convenient to automation equipment and import, stay in grade, effectively improve production efficiency and reduce production cost.
