Description
Technical field
The present invention relates to a kind of connection box of electric energy meter post of built-in arc spring pad, the particularly connected mode of connection box of electric energy meter terminal and wire, belong to the electrical equipment technical field.
Background technology
At present, on market, widely used connection box of electric energy meter terminal all adopts screw to screw the crimping mode, realizes and being connected of wire.With reference to accompanying drawing 1, the wire core is placed in connection terminal, tighten the fastening screw screw mandrel, realization is connected with wire.Although this crimping mode also can realize and being fastenedly connected of wire, but screw screws excessive, can the core of insulated conductor be damaged, crimping trace in various degree appears, in the course of time just can make the structural strength of wire greatly reduce, even there will be disconnected strand or short-term phenomenon, and then cause the contact resistance value at connection terminal place to increase; If screw screws too small, though reduced the impression degree of screw to the wire core, the screw bottom does not fully contact with the wire wicking surface, can cause too contact resistance value to increase.In addition, even if under the prerequisite fully contacted with the wire core in screw bottom, be also a screw rod point and the contacting of conductor thread core surface.Because size and the contact area size of contact resistance value is inversely proportional to, therefore contacting of point and face, directly make contact area reduce, the resistance value increase.As can be seen here, above-mentioned factor all can cause contact resistance value to increase.When the wire current flowing, will generate heat at the connection terminal place, when especially large by load current, the degree of heat of XXL junction more, accelerate the oxidation process of wire core, greatly reduced the serviceable life of connection terminal and wire, also very easily cause the electric energy meter tail and burn phenomenon, even produce larger power outage simultaneously.In addition; often resonance effect can occur on the electrical equipment of day-to-day operation; and the vibration meeting produces harmful effect loosening and even that come off to the fastening screw screw mandrel screwed for a long time; can cause equally electric energy meter and connecting position of wires generation resistance value to increase, tie point heating and the consequence of burning the electric energy meter tail.
Summary of the invention
The object of the invention is to provide a kind of connection box of electric energy meter post of built-in arc spring pad, and by the mode of connection terminal arc spring shim and the crimping of wire core, realization is connected with wire, solves the problem existed in background technology.
Technical scheme of the present invention is:
A kind of connection box of electric energy meter post of built-in arc spring pad, there is the binding post body, the binding post body is provided with connection terminal and bottom binding post line hole, be respectively equipped with fastening screw screw mandrel, fastening screw on the vertical direction in connection terminal and bottom binding post line hole, in connection terminal and below being positioned at the fastening screw screw mandrel, be provided with the arc spring pad; Described connection terminal vertical direction is provided with two fastening screw screw mandrels, two fastening screw screw mandrels below be positioned at connection terminal respectively correspondence be provided with the arc spring pad; Described arc spring pad is " 3 " font; " 3 " font arc spring pad is under the effect of pad spring; produce reacting force upwards; prevented the loosening of fastening screw screw mandrel, the fastening screw screw mandrel acts on the arc spring pad, has protected the wire wicking surface to avoid impression; arc spring pad arch section fully contacts with wire core circular surface; realize the crimping of face and face, increase contact area, reduce contact resistance.
In described binding post line hole, two lateral incisions are greater than the square hole of holding screw shank diameter size.
Be respectively equipped with two fastening screw screw mandrels on the vertical direction in described connection terminal and bottom binding post line hole, two fastening screws, in bottom binding post line hole, two fastening screw screw mandrel belows, two lateral incisions are greater than the square hole of holding screw shank diameter size, the arc spring pad is horizontally placed between two square holes, the integral width of arc spring pad length and connection terminal is consistent, the width of arc spring pad is slightly less than the width in square hole, the arc spring pad is along moving up and down in the framework of square hole, the arc spring pad is " 3 " font, " 3 " font spring and square hole are low along fully laminating, and produce reacting force upwards under the effect of pad spring, make holding screw more firm, prevented from vibrating becoming flexible and coming off of producing.
The invention has the beneficial effects as follows: protected the wire core; prevented that holding screw from becoming flexible and coming off because of what vibration produced; increased contact area; stopped the heating of connection terminal tie point place and burnt the electric energy meter phenomenon; extended the serviceable life of connection terminal and wire; there are characteristics simple in structure, easy to use.

Embodiment
Below in conjunction with accompanying drawing, by example, the invention will be further described.
With reference to accompanying drawing 2, 3, 4, a kind of connection box of electric energy meter post of built-in arc spring pad, there is binding post body 8, binding post body 8 is provided with connection terminal 1 and bottom binding post line hole 5, be respectively equipped with two fastening screw screw mandrels 4 on the vertical direction in connection terminal 1 and bottom binding post line hole 5, two fastening screws 6, two fastening screw screw mandrel 4 interior two lateral incisions in bottom binding post line holes, below 5 are greater than the square hole of fastening screw screw mandrel 4 diameter, arc spring pad 10 is horizontally placed between two square holes, the integral width of arc spring pad 10 length and connection terminal 1 is consistent, the width of arc spring pad 10 is slightly less than the width in square hole, can be along moving up and down in the framework of square hole to reach the arc spring pad, arc spring pad 10 is " 3 " font, " 3 " font spring also can be low along fully laminating with the square hole, and produce reacting force upwards under the effect of pad spring, make holding screw more firm, prevented from vibrating becoming flexible and coming off of producing.
The course of work: the wire core of wire 2 is inserted in connection terminal 1, rotation tightening screw cap 3, along with fastening screw screw mandrel 4 moves down, arc spring pad 10 guiding line core surface thereupon is close, when the fastening screw screw mandrel rotates to certain position, arc spring pad 10 will fit with the conductor thread core circular surface, because arc spring pad and wire wicking surface profile are approximate, can make the arc spring pad fully contact with core, realized the crimping of face and face, increased contact area, reduced contact resistance, avoided the large problem of contact resistance caused because of point and face contact type.Simultaneously, the fastening screw screw mandrel acts on the arc spring pad, and due to arc spring pad material, to compare copper conductor material compressive resistance large, can not cause the impression phenomenon, reached the purpose of guardwire core.While unscrewing the fastening screw screw mandrel, along with the fastening screw screw mandrel moves up, the displacement of arc spring pad increases, and when screw arrives certain position, the wire core can be extracted in connection terminal, can complete the process of removing wire.
