Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings: as shown in Figures 1 to 8, one
Plant the ANSI compatible single-phase three-phase electrical relay scheme electric energy meter structure of circle table, including base 1, described base 1 be provided with inner cover 2,
Described inner cover 2 is outside equipped with outer housing 3, is provided with first circuit board 21 and the in the cavity that described inner cover 2 and described base 1 are formed
Two circuit boards 22, described base 1 is provided with the first pillar 12, and described first pillar 12 top is provided with the second pillar 121, institute
Stating the second pillar 121 top and be provided with lead 122, described base 1 is additionally provided with card hook part 13, described card hook part 13 is by institute
Stating first circuit board 21 to be stuck in described first pillar 12 and prevent it from departing from, described second circuit board 22 is arranged at described second pillar
On 121, described base 1 being provided with the modular assembly 4 of relay and transformer, described modular assembly 4 is provided with connection and leads
Sheet 41, described guide card 41 passes outside described base 1.The inner cover 2 of this device and outer housing 3, relative to common, highly have increase,
And coordinate the modular assembly 4 of relay and transformer again, hereby be achieved that a kind of phenotype takes into account kinds of schemes.
Described base 1 is provided with the first flange 11, and described inner cover 2 is provided with the second flange 24, described first flange 11
Connected by ultrasonic bond with described second flange 24 thus described inner cover 2 is installed to described base 1.The present invention will surpass
The position of sonic soldering is arranged at base 1 and the edge of inner cover 2, so arranges, and ultrasonic bond position protrudes into the periphery of watchcase, not only
It is greatly promoted welding effect, reduces the damage to internal PCB simultaneously, it is to avoid internal parts receive the impact of ultrasonic bond,
Ensure the quality of product.
It is provided with programmable controller 5 on described second circuit board 22, described inner cover 2 is just being positioned at described programmable controller 5
It is provided above push rod 51, described outer housing 3 is positioned at described push rod 51 and is provided above programming button 71, described programming button 71
Connecting and have shifting part 72, described shifting part 72 rotates and is arranged on the bearing 7 of described outer housing 3, described shifting part 72 and described
It is equipped with through hole on seat 7, lead sealing can be realized by described through hole thus prevent described shifting part 72 from rotating.So arrange,
The present invention can be by programming button lead sealing.
Described second pillar 121 diameter is less than described first pillar 12.The first circuit board 21 of the present invention and second circuit
Arrange porose on plate 22.Therefore the second pillar 121 can be through the hole on first circuit board 21 so that first circuit board 21 can
Fall in the first pillar 12 upper end.And the aperture of second circuit board 22 is less, so the second pillar 121 can be parked in, thus on being formed
Lower two-tier circuit plate.So arrange, rationalize and arrange structure so that the ammeter inner space of this device is sufficient, therefore this
Bright relay and copper-manganese two schemes can be combined into one.
Being provided with battery compartment 6 in being provided with battery compartment draw-in groove 23 and this draw-in groove 23 on described inner cover 2, described battery compartment 6 leads to
Cross fastener 61 to be installed in described draw-in groove 23.
Described inner cover 2 is internally provided with reinforcement 25, and described reinforcement 25 heads on described card hook part 13 and prevents it because becoming
Shape thus described first circuit board 21 cannot be blocked.
Described base 1 is provided with four pairs of wire holes 14.The effect of wire hole 14 allows guide card 41 pass described base 1 exactly
Outward, general ammeter, because the restriction of its internal structural space, therefore, arranges 4 wire holes of two teams the most much of that.But the present invention
Outer housing and inner cover have been re-started design, therefore internal can put into more components and parts, thus this device to be provided with four right
Namely eight wire holes 14.
Under prior art, ANSI circle table copper-manganese and relay scheme can not a kind of phenotype be taken into account, or list, three-phase circle table is not
Can take into account by a kind of phenotype.Case for electric energy meter is equipped with screw fixation method with drain pan, assembles relatively cumbersome.In such limit
Under system, enterprise needs case is opened two kinds of moulds, and cost is high, is inconvenient to produce stock simultaneously.
And a kind of electric energy meter structure provided by the present invention can complete to take into account.Why prior art uses a set of structural member
Cannot compatible relay and copper-manganese two schemes, be because relay and taken up space relatively greatly with transformer, common copper-manganese scheme table
Type limited space, it is impossible to compatible.Can not be by circle table enlarged diameter by ansi standard size limitation, therefore, the present invention is by straight for former table
Footpath inconvenience, increases height, and relay and transformer is combined into one, forms modular construction, so, it becomes possible to
Make full use of space in table.The present invention particular design by relevant portion, is combined into one by relay and copper-manganese two schemes,
Well solve space and the problem of height.
This device is provided with case between inner cover 2 and outer housing 3 and uncaps detection function.Namely it is provided with meter on inner cover 2
Counting apparatus, after the electric energy meter of the present invention installs, outer housing 3 is internal heads on counting assembly.After outer housing 3 is opened, skill
Art device will count.So arrange, then coordinate programming button lead sealing, it is possible to prevent stealing electricity phenomenon to a certain extent.
Screw is not played in the assembling of this device whole table buckle-type, improves production efficiency, reduces cost of labor；And solve IP54
Dustproof and waterproof problem；Also add programming button, be provided with case and uncap detection function.
Protection scope of the present invention includes but not limited to embodiment of above, and protection scope of the present invention is with claims
It is as the criterion, replacement that any those skilled in the art making this technology is readily apparent that, deforms, improve and each fall within the present invention's
Protection domain.
