Abstract
The invention discloses an intelligent energy meter auxiliary terminal leaf-spring-type wire connector, which comprises an insulation fixed plate, wherein two ends of the insulation fixed plate are respectively fixedly provided with an elastic tightening clamp, and the middle part of the insulation fixed plate is provided with a row of metal leaf springs. The insulation fixed plate is a rectangular insulation plastic fixed plate, and the insulation fixed plate is provided with threaded fixed holes to be in thread connection with the elastic tightening clamp and the metal leaf springs. The elastic tightening clamp comprises a soleplate and clamping plates which are arranged on two sides of the soleplate, and the waist positions of the clamping plate are retracted so as to enable the upper ends of the two clamping plates to form a V-shaped opening structure. One end of each metal leaf spring is provided with a 20-DEG slope, and the top end of the slope is connected with a platform. The wire connector is simple in structure, low in cost and capable of improving the meter calibration quality and efficiency.
Description
Technical field
The present invention relates to the auxiliary terminals of intelligent electric energy meter electric wire connecting junction.
Background technology
Auxiliary terminal of electric energy meter electric wire connecting junction in the prior art, the most common and widely used is the electric wire connecting junction that uses metallic conductor crocodile clip clamping connection auxiliary terminal of electric energy meter to obtain signal and be plugged into electric energy meter calibrating apparatus by being soldered to crocodile clip afterbody wire transmission.This connector arrangement needs electric energy meter at its auxiliary terminal (at least 6) L-type sheet metal one end to be installed to use the auxiliary terminal screw to be fixed in electric energy meter, one end is used for clamping connection, perhaps uses short lead one end fixedly to draw the exposed clamping connection that is used for of the signal other end of auxiliary terminal with the auxiliary terminal screw.
The defective of doing like this is: at first waste of material is serious, need to connect by extra connector, every electric energy meter all needs the extra connector more than 6, and this connector of tool need not to use the waste that causes material and the increase of electric energy meter manufacturing cost when installing and using electric energy meter; Next is that wiring efficient is low, owing to need manual wiring repeatedly and need one by one corresponding its terminal clamping-line, easily the misconnection virtual connection counteracts the calibration operation of electric energy meter and expends the plenty of time; That the electric wire connecting junction reliability is low at last, because auxiliary terminal is arranged tight metal clip the end of a thread and is easily touched and be short-circuited, or because the high damage that metal clip and wire bonds part occur easily of the frequency of utilization of electric wire connecting junction causes and connects the bad and wire of crab and peg graft partly easily to get loose and cause signal can't be delivered to electric energy meter calibrating apparatus, affect calibration quality and efficient.
Summary of the invention
Technical matters to be solved by this invention just provides a kind of elastic sheet type wire connector for auxiliary terminals of intelligent electric energy meter, and is simple in structure, with low cost, improves calibration quality and efficient.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: elastic sheet type wire connector for auxiliary terminals of intelligent electric energy meter, it is characterized in that: comprise an insulation fixing plate, elastic fastening folder is fixed respectively at described insulation fixing plate two ends, is provided with row's metal clips in the middle of the described insulation fixing plate.
Preferably, described insulation fixing plate is rectangular ambroin fixed head, screw fixed orifice and elastic fastening folder and metal clips is set on the described insulation fixing plate realizes that screw fixes.
Preferably, described elastic fastening folder comprises base plate and is located at the clamping plate of base plate both sides that described clamping plate tighten up at waist location and make two clamping plate upper end form the V-arrangement hatch frame.
Preferably, described metal clips one end is provided with the slope of 20 degree, and top, described slope connects a platform.
Preferably, described elastic fastening folder is the spring steel structure, and described metal clips is the high resiliency steel structure.
Beneficial effect of the present invention is:
(1) the effective serious forgiveness of contact is high, but surface of contact is difficult for virtual connection greater than by the terminal hole contact when adopting sheet metal contact terminal screw, and tool shell fragment crimping pressure is fixed than Xiao Yi;
(2) be difficult for being subjected to displacement and fine-tuning, pressure is offset by the sheet metal elastic deformation when adopting the shell fragment contact, misalignment causes displacement to cause loose contact or virtual connection when having evaded employing binding post mode, and can finely tune the shell fragment contact point by the screw that is connected and fixed plate and metal clips;
(3) need not the location, the present invention adopts the V-arrangement opening folder at fixed head two ends to be fixed on the thin-wall shell at intelligent electric energy meter terminal box two ends, and the large and location electric energy meter thin-wall shell of V-shaped part opening only also more obviously need not to locate by acting on pressure on the fixed head and just V-shaped part can be pressed in the electric energy meter shell and just can realize automatic location;
(4) disconnect conveniently, adopt the fastener of hollow three-legged structure can utilize its hollow space to be the outside application of force dismounting of center of effort;
(5) simple in structure, improvement cost is cheap, the real novel wire that adopts of this usefulness welds respectively the mode that the shell fragment tail end independently is plugged in the corresponding socket of calibrator for watt-hour meter, synthesize the mode that one bus is connected to each socket of stage body after also can adopting welding, need not to change a large amount of transformation fundses of verifying attachment original structure saving, and the present invention is without the easy loss part such as spring, block reinforcement, dependable performance with low cost.
