In view of above-mentioned prior art, be necessary to be improved the connection terminal structure of existing breaker of plastic casing.For this reason, the applicant has done actively and effectively to explore, and finally defines technical scheme described below.
Summary of the invention
The purpose of this utility model is the binding post that will provide a kind of breaker of plastic casing, and it is easy for installation, can ensure the insulation property of circuit breaker and the reliability of electrical connection simultaneously.
The purpose of this utility model reaches like this, a kind of binding post of breaker of plastic casing, comprise and be arranged on terminal working of plastics on circuit breaker base and line bank and nut, described base all offers binding post chamber in line two ends arbitrary pole wiring part, described line bank is contained in described binding post chamber, described terminal working of plastics is placed between described line bank and the bottom surface of base, the shape of described terminal working of plastics is a cuboid, the groove matched with the appearance profile of described nut is offered in the middle of the top of terminal working of plastics short transverse, described nut to be placed in groove and to be positioned at the below of line bank, it is characterized in that: described terminal working of plastics also offers a blind hole at the middle part of short transverse, this blind hole to be positioned at immediately below described groove and to communicate with groove.
In a specific embodiment of the present utility model, described terminal working of plastics is formed with locating piece respectively on the both sides wall body of Width, correspondingly, described base offers for the stopper slot for described locating piece scarf on chamber, the both sides wall in binding post chamber.
In another specific embodiment of the present utility model, described terminal working of plastics is formed with chamfered section respectively towards the two ends of the side, side in binding post chamber in a state of use.
After the utility model adopts said structure, the beneficial effect had: not only facilitate installation, and offer a blind hole communicated with groove at the middle part of short transverse due to terminal working of plastics, the bottom structure of terminal working of plastics is made to be enclosed construction, this ensure that there are enough electric clearances between terminal screw and mounting panel, improve the insulation property of circuit breaker, ensure the reliability of electrical connection.
