Description
Technical field
The utility model relates to low-voltage circuit breaker, is specifically related to a kind of electronic conjunction and the brake separating mechanism with the protective device of automatic reclosing function.
Background technology
The protective device with automatic reclosing function is used for carrying out indirect contact protection to people; also can be used to prevent because of apparatus insulated damage; produce earth fault current and the fire hazard that causes; and can be used to the overload and the short circuit that distribute electric energy and protection circuit and power-supply device, also can be used as the use that the infrequently conversion of circuit and motor infrequently start.This serial existing residual current circuit breaker adopts plastic handle, though insulation, assemble loaded down with trivial details, consumptive material is many, and plastic handle is equipped with metalwork, and when this metalwork coordinates with connecting rod, friction is comparatively large, can affect conjunction and the separating brake of product time serious; Separately because existing circuit breaker drives the ratchet mechanism structure of gear wheel running loaded down with trivial details, assembling complexity, easy to wear, and when energising runs, could operate by driven gear after driven by motor ratchet idle running LAP, add product closing time.
Utility model content
The purpose of this utility model is to provide a kind of and reduces the manufacturing cost of product, strengthens the stress-bearing capability of gear; Bar cover to coordinate with connecting rod and not only solves handle Insulation Problems and all have self lubricity and high-wearing feature, be energized operation time, motor and gear wheel run-in synchronism, the protective device with automatic reclosing function of the closing time of reduction product.
The technical solution of the utility model is, a kind of protective device with automatic reclosing function, a kind of protective device with automatic reclosing function, comprise middle cover, gear wheel, connecting rod, motor, handle, lever, countersunk head screw, described motor is arranged in the installing hole in described middle cover, also be fixedly connected with described motor by unilateral bearing in the middle of described gear wheel, described gear wheel surface is protruded side injection moulding and is provided with inserts, described handle riveted joint is arranged on above described lever, described connecting rod two ends are connected with described handle and described inserts respectively, when this serial protective device energising runs, driven by motor gear wheel and unilateral bearing clockwise direction run.
In the utility model preferred embodiment, described motor shaft top is also fixed by circlip for shaft.
In the utility model preferred embodiment, described connecting rod is adopted countersunk head screw with described handle and is connected by bar cover.
In the utility model preferred embodiment, described connecting rod is reliably connected by circlip for shaft by described inserts top.
In the utility model preferred embodiment, described gear wheel is that nylon material adds glass or polyphenylene sulfide or polytetrafluoroethylene and makes, and inserts is metallic article.
In the utility model preferred embodiment, described bar cover and connecting rod are that nylon material adds glass or polyphenylene sulfide or polytetrafluoroethylene and makes.
Described in the utility model is a kind of protective device with automatic reclosing function, and the utility model reduces the manufacturing cost of product under the prerequisite not affecting properties of product; Inserts strengthens the stress-bearing capability of gear; Bar cover and connecting rod are nylon material and add glass or polyphenylene sulfide or polytetrafluoroethylene, have insulating properties, self lubricity and high-wearing feature, and bar cover serve the effect of pad; When energising runs, motor and gear wheel run-in synchronism, reduce the closing time of product.
Accompanying drawing explanation
Fig. 1 is a kind of explosive view had in protective device one preferred embodiment of automatic reclosing function of the utility model;
Fig. 2 is a kind of structural representation had in another preferred embodiment of protective device of automatic reclosing function of the utility model.
Embodiment
Below preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Described in the utility model is a kind of protective device with automatic reclosing function, as shown in Figure 1 with Figure 2, comprises middle cover 1, gear wheel 2, connecting rod 3, motor 4, handle 5, lever 6, countersunk head screw 7.
Described motor 4 is arranged in the installing hole in described middle cover 1, is also fixedly connected with described motor 4 by individual event bearing 8 in the middle of described gear wheel 2, and the motor shaft top on described motor 4 is also fixed by circlip for shaft 9.
Described gear wheel 2 surface is protruded side injection moulding and is provided with inserts 10.
Described handle 5 riveted joint is arranged on above described lever 6.
Described connecting rod 3 two ends are connected with described handle 5 and described inserts 10 respectively.
Described connecting rod 3 is adopted countersunk head screw 7 with described handle 5 and is connected by bar cover 11.
Described connecting rod 3 is reliably fixedly connected with by circlip for shaft 9 by described inserts 10 top.
When having the protective device energising operation of automatic reclosing function, motor 4 drives gear wheel 2 and unilateral bearing 8 clockwise direction to run.
Described gear wheel 2 is made for nylon material adds glass or polyphenylene sulfide or polytetrafluoroethylene, and inserts 10 is metallic article.
Described bar cover 11 and connecting rod 3 are made for nylon material adds glass or polyphenylene sulfide or polytetrafluoroethylene.
When this serial protective device energising runs, driven by motor gear wheel and unilateral bearing clockwise direction run, and because gear wheel is working of plastics, its working position contacted with connecting rod is stressed comparatively large, easy fracture, therefore adopts metal insert, strengthens its stress-bearing capability; And connecting rod and handle contact position, overlapped by bar and connect, not only reduce friction of motion, also serve insulating effect, strengthen personal safety; Lever and handle adopt rivets, and effectively reduces labour cost and fee of material.
Described in the utility model is a kind of protective device with automatic reclosing function, and the utility model reduces the manufacturing cost of product under the prerequisite not affecting properties of product; Inserts strengthens the stress-bearing capability of gear; Bar cover is nylon material with connecting rod and adds glass or polyphenylene sulfide or polytetrafluoroethylene and make, and have insulating properties, self lubricity and high-wearing feature, and bar cover serves the effect of pad; When energising runs, motor and gear wheel run-in synchronism, reduce the closing time of product.
The foregoing is only embodiment of the present utility model; but protection range of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection range of the present utility model.Therefore, the protection range that protection range of the present utility model should limit with claims is as the criterion.
