Description
Technical field
The utility model relates to the spark killer that uses in the Circuits System, the integrated spark killer that uses in particularly a kind of Circuits System.
Background technology
Spark killer is absorption and the arc extinguishing that is used at the electric spark that produces in the Circuits System, improves the fail safe and the stability of Circuits System.Present known spark killer is exactly a RC series circuit from circuit analysis, is divided into two classes from contour structures: wiring board split class and plastic casing encapsulation one class.
Wiring board split class is installed in resistance capacitance on one wiring board exactly and connects as its name suggests, and its class of insulation is not enough, easily damages in a humid environment, and use occasion is limited to.
Plastic casing encapsulation one class connects resistance capacitance the back exactly and directly is rolled into integrated element with a plastic casing, the exposed single strand of copper wire of hard is drawn as lead-in wire in the bottom of its plastic casing, this type of spark killer is more convenient than the board-like use of circuit, the scope of application is wider, but still there is defective in it: 1, the resistance capacitance outside is directly wrapped up by plastic casing, structural strength is not high, and is fragile in the transportation; 2, because of no mounting part, use installation inconvenient unreliable, use occasion is limited, only is suitable for assigning on wiring board being located by connecting.
Summary of the invention
The purpose of this utility model provides integrated spark killer, to solve the technical problem that existing spark killer structural strength is not high and use installation inconvenience.
For achieving the above object, the technical solution adopted in the utility model is: a kind of integrated spark killer, comprise a housing, establish the resistance and the electric capacity that connect in the housing, and outside housing, draw lead-in wire, innovative point is: also comprise a support, this support is installed base plate by one and the vertically disposed supporting bracket that makes progress on the base plate is installed and constitutes, described housing lower ending opening, its sheathed from the top down being supported on the supporting bracket, its lower ending opening connects by the base plate capping is installed, and the base plate edge is installed is stretched out, and its extension is provided with and installs and fixes hole or groove.
Related content in the technique scheme is explained as follows:
1, in the such scheme, " on " D score is by the definition of state as shown in Figure 1.
2, in the such scheme, the quantity of resistance and electric capacity in the described housing, connecting circuit is a prior art, and is concrete: single-phase spark killer connecting circuit as shown in Figure 5, promptly electric capacity and resistance directly series connection draw two ends; Three-phase spark killer connecting circuit, promptly the series arm of three electric capacity and resistance connects into triangle and sees accompanying drawing 1, perhaps connects into star.Draw lead-in wire on each branch road tie point.
3, in the such scheme, described housing is fire-retardant housing, to avoid external firing it is injured.
4, in the such scheme, be welded to connect between described resistance and electric capacity.
5, in the such scheme, described lead-in wire is the flexible cord of tape insulation cover, connects so that use.
6, in the such scheme, be covered with one deck shielded metal net on the described shell inner surface, to improve antijamming capability and minimizing electromagnetic radiation to external world.
7, in the such scheme, described housing and installation base plate constitute the interior cast of cavity normal temperature resin epoxy packages and solidify.Plug hole is offered at the concrete middle part that base plate is installed, and pours into a mould normal temperature resin epoxy packages to this in housing.
Because the utilization of technique scheme, this use is novel compared with prior art to have the following advantages:
1, because the utility model has been set up support especially, structural strength improves greatly, thereby not fragile in transit;
2, because the utility model bottom is provided with the installation base plate, the installing and locating when being convenient to use has improved the convenience of installing and using;
3, because the utility model adopts fire-retardant housing, increased anti-flammability, can avoid the injury of external firing integrated spark killer self;
4, because the utility model has been set up shielded metal, increased substantially integrated spark killer anti-jamming capacity, and can reduce less the external electromagnetic radiation of integrated spark killer self.
5, because the utility model connects firmly into an integral body with normal temperature resin epoxy, the class of insulation of integrated spark killer is increased substantially, adapt to various adverse circumstances.
