Description
Technical field
The utility model relates in electric energy meter connection area, in particular to a kind of device that can prevent electric energy meter from missing line.
Background technique
Earliest electric energy meter (also referred to as ammeter) is 1881 according to made of electrolysis principle, although every weight of this electric energy meter
It is very heavy up to tens kilograms, and the guarantee without precision, still, at that time still by an invention of great significance as scientific and technological circle by
To the attention and commendation of people, and it is soon used in engineering, with the development of science and technology, 1888, alternating current
Discovery and application, and the development to electric energy meter is put forward new requirements.By the effort of scientist, induction type electric energy meter is born
, electric energy meter is necessary equipment to be used in factory and people's daily life at present.
However, construction personnel is careless sometimes when carrying out batch replacement electric energy metering device, no twist-on enters electric energy
Table into and out of line screw, cause client to be unable to normal electricity consumption or be easy to burn out customer electricity equipment.
Utility model content
The purpose of this utility model is that have above-mentioned shortcoming to solve electric energy meter connection, providing one kind can
Prevent electric energy meter from missing the device of line, it is characterized in that: including electric energy dial plate and the terminal box below the electric energy dial plate, institute
It states and is equipped with several binding posts in terminal box, the binding post is internally provided with equipped with spring, and the spring one end is fixed to be connected
It is connected to binding post inside top surface, is equipped with binding post screw hole in the binding post lower end, the binding post screw hole is used for and wiring spiral shell
Silk cooperation, and when the other end of the spring is located at binding post screwhole position, the spring is in compressive state.
Further, the spring surface is circular contact face.
Further, binding post is 4.
Further, when the terminal screw that construction personnel does not have twist-on to enter electric energy meter, inlet-outlet line, which just will pop up, to be come, thus
Remind construction personnel that terminal screw is not twisted.
The utility model has the beneficial effects that
1, it can obviously see that inlet-outlet line is not twisted.
2, spring surface is circular contact face, can be come into full contact with conducting wire
3, structure is simple, strong applicability, and the present apparatus can be applied to electric energy meters all currently on the market.
Detailed description of the invention
Fig. 1 is that the utility model prevents the electric energy meter from missing the apparatus structure schematic diagram of line.
Wherein, 1- spring, 2- binding post, 3- electric energy dial plate, 4- binding post screw hole.
Specific embodiment
A kind of device for preventing electric energy meter from missing line, it is characterized in that: including electric energy dial plate and being located at the electric energy dial plate
The terminal box of lower section, the terminal box is interior to be equipped with several binding posts, and being internally provided with equipped with spring for the binding post is described
Spring one end is fixedly connected on binding post inside top surface, is equipped with binding post screw hole, the binding post spiral shell in the binding post lower end
Hole is used to cooperate with terminal screw, and when the other end of the spring is located at binding post screwhole position, the spring is in
Compressive state.
The spring surface is circular contact face.
Binding post is 4.
Specifically, spring can be added inside connection box of electric energy meter column by preventing electric energy meter from missing line, it is linked as with connection box of electric energy meter column
One, when the terminal screw that construction personnel does not have twist-on to enter electric energy meter, inlet-outlet line, which just will pop up, to be come, to remind construction personnel
Terminal screw is not twisted.
Structure is simple, strong applicability, and the present apparatus can be applied to electric energy meters all currently on the market；It can obviously see
Electric energy meter inlet-outlet line is not twisted；Spring surface is circular contact face, can be come into full contact with conducting wire.
Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can be with other sides
Formula realizes that any obvious replacement is in the protection model of the utility model without departing from the concept of the premise utility
Within enclosing.
Claims (4)
