Abstract
The invention discloses an integrated combined terminal row. The combined terminal row comprises terminals of a strong current terminal row and a weak current terminal row and is characterized in that the combined terminal row also comprises a mounting box body, a mutual inductor, coils and movable and static contact pieces of a relay, wherein the mounting box body is provided with installation positions of the terminals of the strong current terminal row, the mutual inductor and the coils and movable and static contact pieces of the relay, the output end of the fixed contact pieces of the relay is used to connect with the mutual inductor in series and then extend to the terminals of the strong current terminal row to connect with an external power supply, and the terminal of the movable terminal extends to the back of the terminals of the strong current terminal row to be introduced. The integrated combined terminal row of the invention can reduce the contact resistance and the total calorific power of an electric energy meter so that the installation efficiency of the electric energy meter is significantly improved, the operation is reliable, the structure is compact, the service life is increased and the cost is reduced.
Description
Technical field
The present invention relates to a kind of terminal board that is used for electric energy meter.
Background technology
Existing electric energy meter generally all has terminal board, instrument transformer, relay, between them textural be separate, when being installed, electric energy meter needs with securing member and connector they fastening being installed in the electric meter box are connected (as shown in Figure 6) with cable to each electric connection point then.Very consuming time when the electric energy meter of this structure is installed, installation quality can not get ensureing, and because electric connection point is many, caloric value is big, and is very unfavorable to the useful life and the reliability of electric energy meter, causes overall cost up.
Summary of the invention
The object of the present invention is to provide a kind of instrument transformer, relay and terminal board function of collecting is the integrated combined terminal row of one.
Integrated combined terminal row of the present invention, comprise forceful electric power terminal board terminal and weakness terminal board, also comprise line bag and movable contact spring and static contact that box body, instrument transformer, relay are installed, have on the described installation box body forceful electric power terminal board terminal the installation position, have instrument transformer the installation position, the installation position of line bag and the movable contact spring and the static contact of relay is arranged, the output of the static contact of described relay is used for extending to forceful electric power terminal board terminal behind the serial mutual inductor and is electrically connected with external power supply, and the movable contact spring terminal is drawn after extending to forceful electric power terminal board terminal.
For the heating that prevents relay coil influence to other members, box body is installed is had two chambeies up and down, the movable contact spring of described relay and static contact are arranged in epicoele that box body is installed and by a loam cake capping, the line bag of relay is fixed in the cavity of resorption that box body is installed, by the lid of cap seal once, forceful electric power terminal board terminal is positioned at the front end that box body is installed.
For the ease of the installation of light current terminal board and adapt to the number of terminals and the shape of various different light current terminal boards, described integrated combined terminal row, leave the installation site of light current terminal board on the described installation box body, but this light current terminal board integral demounting be fixed on and install on the box body.
The present invention makes an integral body with forceful electric power terminal board terminal, relay, instrument transformer, can bring two tangible advantages: the one, cancelled the many places tie point that comprises between terminal board and the relay, reduced contact resistance greatly, reduce the caloric value in the ammeter, increased the ammeter reliability of operation; The 2nd, the present invention is directly used in the electric energy meter after producer makes, and makes the installation process of electric energy meter simple more and quick, makes simultaneously to have had bigger space in the electric energy meter, can make the volume of electric energy meter do forr a short time in other words.Effectively reduce overall cost.

Embodiment
Integrated combined terminal row of the present invention as can be seen still has forceful electric power terminal board terminal 1 from Fig. 1 to Fig. 3, light current terminal board 5, box body 2 is installed in addition, instrument transformer 3, relay 4, relay 4 has line bag 41, movable contact spring 42 and static contact 43, box body 2 is installed is had epicoele 21 and cavity of resorption 22, loam cake 23 and lower cover 24, forceful electric power terminal board terminal 1 is installed in the front end that box body 2 is installed, instrument transformer 3 is installed in the centre position that box body 2 is installed, the movable contact spring 42 of relay and the installation position of static contact 43 are in the epicoele 21 that box body 2 is installed, by loam cake 23 cappings, the installation position of the line bag 41 of relay is in the cavity of resorption 22 of mounting box 2, by lower cover 24 cappings.Light current terminal board 5 removably is fixed on to be installed on the box body 2, and is positioned at the top of instrument transformer 3, and light current terminal board 5 can be made the terminal board of multi-form and different wiring quantity, changes according to different clients' demand at any time.
Fig. 4 has reflected the annexation between static contact 43, movable contact spring 42, instrument transformer 3 and the forceful electric power terminal board terminal 1 of relay, the output of static contact 43 is used for extending to forceful electric power terminal board terminal 1 behind the serial mutual inductor 3 and is electrically connected with external power supply, and movable contact spring 42 terminals are drawn after extending to forceful electric power terminal board terminal 1.
After integrated combined terminal row of the present invention as can be seen from Figure 5 becomes one forceful electric power terminal board terminal, light current terminal board, instrument transformer, relay, its contact reduces in a large number, and volume also diminishes, and the space in the electric meter box is increased, significantly reduced contact resistance, reduced the caloric value in the ammeter, improved radiating condition, the total caloric value of electric energy meter is reduced, reliability improves, compact conformation, increase useful life, and cost reduces.The present invention can make finished product in factory in advance in addition, has therefore reduced field erected workload, and the ammeter installation effectiveness is improved greatly.
