Abstract
The invention relates to a plastic breaker electronic type releaser device, including a circuit board control module and a current transformer module. The circuit board module is composed of an upper half shell (1) and a lower half shell (2), and the inside of the circuit board module is mounted with a circuit board; the lower part of the lower half shell (2) is preset with an inserting needle (9) which exposes out of the lower half shell (2). The circuit board control module is fixed with the breaker upper cover through a fixed hole (10); the current transformer module is composed of a left half shell (8) and a right half shell (9), wherein the three-phase current transformer is arranged inside the current transformer, preset with an inserting hole (30 on the upper. The current transformer module is fixed with the breaker base through the base connecting hole (5) of the current transformer (6) outgoing line row. Two modules are matched each other when the breaker upper cover is matched with the base, and the butt of the circuit board and the current transformer are completed through the matching inlaying grafting of the two modules.
Description
Technical field
The present invention relates to a kind of plastic case breaker electronic type release apparatus.
Background technology
In the prior art, current transformer is installed among the circuit breaker base for exposed in the electronic type release, the wiring board control unit is exposed to be installed in the breaker upper cover, loam cake cooperates when installing and ABC threephase current transformer lead-out wire contact pin need be flexible coupling with the wiring board terminal is corresponding one by one with base, installing space is narrow and small, waste time and energy, electric property is difficult for guaranteeing, and because wiring board and current transformer are exposed the installation, degree of protection is low, is unfavorable for the raising of EMC characteristic, when short-circuit conditions takes place, wiring board and current transformer are subjected to the damage of high temperature and air pressure easily, reduce life of product.
Summary of the invention
Technical problem to be solved by this invention is; a kind of improved electronic type release apparatus is provided; breaker upper cover in sealing cooperates with the installation of realization wiring board summation current transformer in the base space; require effectively protection circuit plate summation current transformer; improve degree of protection; easy for installation, electric property is safe and reliable.
The technical scheme that solves its technical problem employing is: design two installed modules, a module is installed the wiring board control unit, and contact pin is reserved in the below, fixedlys connected with breaker upper cover simultaneously; An installation threephase current transformer, jack is reserved on top, fixedlys connected with the circuit breaker base simultaneously; Breaker upper cover and base are being installed when cooperating, the grafting that cooperatively interacts simultaneously of two modules, and wiring board is pegged graft by cooperating of two modules with the butt joint of current transformer and is finished.
A circuit board control module and a current transformer module have been the present invention includes.Circuit board control module comprises upper half shell (1) and lower half shell (2), breaker upper cover inside is fixed in by fixing hole (10) in upper half shell (1) and lower half shell (2) assembling back, wiring board is in upper half shell (1) and lower half shell (2) inside, lower half shell (2) has pin holes, and the contact pin on the wiring board (9) is exposed to outside the lower half shell (2) by pin holes.Current transformer module comprises left half shell (8) and right half shell (7), current transformer (6) is in the assembly space inside of left half shell (8) and right half shell (7), the outlet row of current transformer (6) stretches out outside the shell by the fabrication hole of left half shell (8) and right half shell (7), the outlet row of current transformer (6) has base connecting hole (5), and left half shell (8) and right half shell (7) have louvre (4); A left side half shell (8) and right half shell (7) mating surface are reserved installation opening, and current transformer (6) three-phase lead-out wire passes installation opening fixedlys connected with jack (3), and fixedly connected good jack (3) is fixed on corresponding installation opening; Current transformer module utilizes current transformer outlet row's base connecting hole (5) to be fixed among the circuit breaker base.The installation of wiring board contact pin (9) summation current transformer jack (3) cooperates guiding to cooperate guiding consistent with the installation of breaker upper cover and base, and the installation of finishing wiring board contact pin (9) summation current transformer jack (3) when the installation of breaker upper cover and base cooperates cooperates.
