Compared with the prior art, the ammeter has a simple manufacturing technique, the reprocessing rate is low, material cost, manual assembly cost and operation cost are low, the accuracy is improved and the reliability is greatly improved.
Description
Technical field
The utility model relates to a kind of electric energy meter.
Background technology
At present, the input and output of electric energy meter mainly are divided into two parts, and some is a forceful electric power, i.e. phase line current input and output; Another partly is light current, the i.e. input and output of electric energy meter external-internal control signal.And the connection of the forceful electric power light current of all electric energy meter inside substantially all is to adopt the flexible cord cable to connect, and it is as follows with quantity that it connects particular location: one, the signal terminal of terminal row light current all signal ports (as multi-functional port, pulse port, 485 ports, jumping port, control port etc.) partly is connected by eight cables with pcb board; Two, the sampling of the forceful electric power on the manganese copper diverter partly is connected with pcb board by three cables; Three, zero line bonding jumper place has the single line cable to be connected with pcb board.
Traditional wired method in this electric energy meter, though popularized a lot of years, but still have a lot of shortcomings: at first, many cables that weld on each parts have not only increased use cost, cause electric energy meter Material Cost and operation cost too high, also strengthen manufacturing process, reduced throughput rate; Secondly, the numerous measuring accuracy of electric energy meter deviations that promptly can cause of cable of band different insulative layer color are too big, and the cable insulation course is punctured by strong voltage easily and damages electric energy meter, and reliability is not high, and the also easy wrong plug cable of direct labor causes doing over again in batches; At last, adopt the pcb board of this connection must adopt screw retention on the electric energy meter drain pan, waste time and energy, and the supporting plugs and sockets of itself and cable occurs direction easily and connect instead, cause deficient purchase to be done over again.
The utility model content
The purpose of this utility model is to provide that a kind of production cost is lower, production efficiency is high, measure electric energy meter more accurately.
The electric energy meter that the utility model provides, comprise pcb board, zero line bonding jumper, manganese copper diverter and have signal terminal and the terminal row of current terminal, on described zero line bonding jumper, be provided with the connecting pin that is connected with pcb board, on described manganese copper diverter, be provided with the sampling pin that is connected with pcb board, described signal terminal adopts screw to connect with being connected of pcb board, and described connecting pin all adopts grafting with the sampling pin with being connected of pcb board.
Adopt screw to be connected between described zero line bonding jumper and the current terminal.
Adopt screw to be connected between described manganese copper diverter and the current terminal.
Compared with prior art, the utlity model has following advantage:
1, production technology is simple, and production efficiency has improved more than 30% than original old-fashioned electric energy meter.
2,, occur never again causing the phenomenon of doing over again because of the cable wrong plug because of having cancelled the flexible cord cable.
3, the removal of numerous cables greatly reduces Material Cost and artificial assembly cost and operation cost.
4, the accuracy of measuring of electric energy meter has also been got rid of because of cable cancellation and has been disturbed more accurately, and the reliability aspect also improves greatly, occurs causing because of cable the phenomenon of withstand voltage puncture never again.
5, the supporting plugs and sockets of pcb board and cable is also along with cable is cancelled together, occurs deficient purchase never again and causes the phenomenon of doing over again.
6, can directly be used for the support fixation pcb board because of signal terminal is connected with screw between pcb board, cancel being exclusively used in the fixedly gib screw of pcb board in drain pan.

Embodiment
Can find out from Fig. 1 and Fig. 2, electric energy meter of the present utility model comprises pcb board 1, zero line bonding jumper 2, manganese copper diverter 3, terminal row 4, attachment screw 5 and terminal screw 6, wherein terminal row 4 comprises signal terminal 41 and current terminal 42, on each signal terminal 41, be provided with threaded hole, the corresponding position that is used for the signal transmission with each signal terminal 41 on pcb board 1 all has corresponding pad hole, attachment screw 5 passes pad hole on the pcb board 1 and locks in the threaded hole on the signal terminal 41, thereby has connected being electrically connected of signal terminal 41 and pcb board 1.On zero line bonding jumper 2, be provided with connecting pin 21, on manganese copper diverter 3, be provided with sampling pin 31, each connecting pin 21 and sampling pin 31 extend upward, its top all has and is used for the contact pin structure that signal transmits, the corresponding position that is used for the signal transmission with each connecting pin 21 and sampling pin 31 on pcb board 1 all has the jack of conduction, the contact pin structure of each connecting pin 21 and sampling pin 31 bottoms can both be inserted in the jack of pcb board 1 each function correspondence, realizes the transmission of various signals.The other end of zero line bonding jumper 2 and manganese copper diverter 3 then is locked at above the current terminal 42 by terminal screw 6, thereby realizes being electrically connected.
Assembling process of the present utility model is as follows:
One, at first pcb board 1 is fixed on above the terminal row 4 pairing signal terminals 41, and then the pad hole and signal terminal 41 lockings of attachment screw 5 being passed 1 respective signal port of pcb board, after locking this attachment screw 5, pad plane above the screw head of attachment screw 5 upper ends and the pcb board 1 closely contacts, each signal port is connected fully by the electric control circuit of attachment screw 5, signal terminal 41, pulse screw and electric energy meter outside on the inner pcb board of the electric energy meter this moment 1 pad hole, has realized that zero cable electrical connects firmly.
Two, after pcb board 1 and terminal row 4 assemblings are in aggregates, the contact pin with each connecting pin 21 and sampling pin 31 tops can both insert in the jack of pcb board 1 each function correspondence earlier; Again the sampling pin above the manganese copper diverter 3 31 is inserted in the pcb board 1 pairing jack, threaded hole above the while align currents terminal 42, and then the fixed orifice that terminal screw 6 is passed on the manganese copper diverter 3 is locked at above the current terminal 42, finish the assembling of manganese copper diverter 3, connecting pin on the zero line bonding jumper 2 21 is inserted in the pcb board 1 pairing jack, threaded hole above the while align currents terminal 42, and then the fixed orifice that terminal screw 6 is passed on the zero line bonding jumper 2 is locked at above the current terminal 42, finishes the assembling of zero line bonding jumper 2; Again zero line bonding jumper 2 and manganese copper diverter 3 top connecting pins 21 and the pin 31 of sampling are got final product with pcb board 1 welding curing at last.
