Abstract
The utility model discloses an integral type combined terminal strip, which comprises a strong electricity terminal-strip terminal and a weak electricity terminal strip. The integral type combined terminal strip is characterized by further comprising a mounting box body, a mutual inductor and a coil, a movable contact and a static contact of a relay, the movable contact and the static contact are arranged on the coil, the mounting box body is provided with a mounting position of the strong electricity terminal-strip terminal, a mounting position of the mutual inductor and mounting positions of the coil, the movable contact and the static contact of the relay, an output end of the static contact of the relay extends to the strong electricity terminal-strip terminal to be electrically connected with an external power source after being serially connected with the mutual inductor, and a movable contact terminal is led out after extending to the strong electricity terminal-strip terminal. The integral type combined terminal strip can reduce contact resistance, decreases total heating quantity of an electric energy meter, leads mounting efficiency of the electric energy meter to be increased obviously, is reliable in operation and compact in structure, prolongs service life and reduces cost.
Description
Technical field
The utility model relates to a kind of terminal row that is used for electric energy meter.
Background technology
Existing electric energy meter generally all has terminal row, mutual inductor, relay, between them textural be separate, when being installed, electric energy meter needs with securing member and web member 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, thermal value is big, and is very unfavorable to the serviceable life and the reliability of electric energy meter, causes overall cost up.
The utility model content
It is the integrated combined terminal row of one that the purpose of this utility model is to provide a kind of mutual inductor, relay and terminal row function of collecting.
The utility model integrated combined terminal row, comprise forceful electric power terminal row terminal and weakness terminal row, also comprise line bag and movable contact spring and static contact that box body, mutual inductor, relay are installed, have on the described installation box body forceful electric power terminal row terminal the installation position, have mutual inductor the installation position, the installation position of line bag and the movable contact spring and the static contact of relay is arranged, the output terminal of the static contact of described relay is used for extending to forceful electric power terminal row 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 row 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 row terminal is positioned at the front end that box body is installed.
For the ease of the installation of light current terminal row and adapt to the number of terminals and the shape of various different light current terminal rows, described integrated combined terminal row, leave the installation site of light current terminal row on the described installation box body, but this light current terminal row integral demounting be fixed on and install on the box body.
The utility model is made an integral body with forceful electric power terminal row terminal, relay, mutual inductor, can bring two tangible advantages: the one, cancelled the many places tie point that comprises between terminal row and the relay, reduced contact resistance greatly, reduce the thermal value in the ammeter, increased the ammeter reliability of operation; The 2nd, the utility model 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
The utility model integrated combined terminal row still has forceful electric power terminal row terminal 1 as can be seen from Fig. 1 to Fig. 3, light current terminal row 5, box body 2 is installed in addition, mutual inductor 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 row terminal 1 is installed in the front end that box body 2 is installed, mutual inductor 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 row 5 removably is fixed on to be installed on the box body 2, and is positioned at the top of mutual inductor 3, and light current terminal row 5 can be made the terminal row 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, mutual inductor 3 and the forceful electric power terminal row terminal 1 of relay, the output terminal of static contact 43 is used for extending to forceful electric power terminal row 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 row terminal 1.
After the utility model integrated combined terminal row becomes one forceful electric power terminal row terminal, light current terminal row, mutual inductor, relay as can be seen from Figure 5, 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 thermal value in the ammeter, improved radiating condition, the total thermal value of electric energy meter is reduced, reliability improves, compact conformation, increase serviceable life, and cost reduces.The utility model can be made finished product in factory in advance in addition, has therefore reduced field erected workload, and the ammeter installation effectiveness is improved greatly.
