Mode, simple easy processing.
The technical solution of breaker of plastic casing of the present invention is：
The scheme one of breaker of plastic casing：A kind of breaker of plastic casing, including shell and felt pad, shell are equipped with terminal hole, terminal
One of hole port is located at housing bottom, it is characterised in that：Felt pad includes more than two terminal holes with housing bottom
The insulation stabilizer blade of cooperation is connected between each insulation stabilizer blade by connection sheet, passes through screw threads for fastening at least one connection sheet
Part links with shell.The breaker of plastic casing uses the mounting structure of screw threads for fastening, by felt pad screw threads for fastening in Shell of circuit breaker
Bottom surface, it is easy to operate, firmly install, is not easily to fall off, the structure of insulate stabilizer blade and connection sheet increase breaker and mounting plate it
Between insulation distance, ensure that the safety of circuit.
The scheme two of breaker of plastic casing：On the basis of scheme one, each insulation stabilizer blade "-" type arrangement.The felt pad
Upper insulation stabilizer blade structure in one line, simple easy processing are easily installed.
The scheme three of breaker of plastic casing：On the basis of scheme one or two, the thickness of the insulation stabilizer blade is more than connection sheet
Thickness, it is raised inwardly relative to connection sheet.Using the felt pad of this structure, it is disconnected to be formed by bulge-structure insertion plastic housing
In the terminal hole of road device, it can be made to firmly install, be not easy to loosen, increase the insulation distance between breaker and mounting plate.
The scheme four of breaker of plastic casing：On the basis of scheme three, the lateral surface of the insulation stabilizer blade and connection sheet it is outer
Side is concordant.The breaker of plastic casing felt pad of the structure, in such a way that insulation stabilizer blade is concordant with connection sheet lateral surface, simply
Easy processing.

Specific implementation mode
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment one of breaker of plastic casing of the present invention is：As shown in Figure 1, the breaker of plastic casing include shell 1 and absolutely
Edge pad 4, shell 1 is equipped with corresponding eight terminal holes 2, while also having several threaded holes 3, is used for the installation of felt pad 4.Such as
Shown in Fig. 2, which is nylon material, and middle section is connection sheet 5, has through-hole 7, screw rod 6 to pass through through-hole 7 in connection sheet 5
Fasten connection, 4 both ends of felt pad insulation stabilizer blade 8 is designed to cylindric, and cylindrical lip is along there is extension 9.
The present invention use process is as follows：First by the contact system of breaker, arc quenching system, operating system, buckle releaser and
Shell installs, and finally installs felt pad 4.When felt pad 4 is installed, first it is passed through on the screw rod 6 and shell 1 of through-hole 7
Threaded hole 3 is aligned, and is then fastened to it with screwdriver, cylindric until stabilizer blade 8 of tightening and insulate fairly falls in terminal hole 2
Until, thus constitute the installation process of felt pad described in the invention on-board the circuit breaker.This felt pad and its installation
Construction profile is simple in structure, firmly installs, is not easily to fall off, can improve the insulation distance between breaker and mounting plate, ensures
The safety of circuit.
The specific embodiment two of breaker of plastic casing of the present invention, with embodiment one the difference is that, in embodiment two absolutely
Not in the same plane, there be the convex of insulation stabilizer blade 8 in the both sides of connection sheet 5 for the lateral surface of edge stabilizer blade 8 and the lateral surface of connection sheet 5
Play part.Screw rod is avoided when being fastened to felt pad 4 using threaded fastener using the mounting structure of this structure
Cap evagination makes spiro rod cap be in the groove that insulation stabilizer blade 8 is constituted with connection sheet 5.
The present invention is not limited to the above-described embodiments, and the insulation of terminal and mounting plate can be not close insulation, in other realities
It applies in example, insulation stabilizer blade 8 may be designed to other shapes, no matter doing any variation in shape at it, every energy realizes embedded terminal
Hole 2, has the function that terminal insulative, each falls within the invention protection domain.
