Abstract
The utility model discloses a low-voltage shunt capacitor with a bolt electrode contacts, comprising a wiring terminal and a main body of capacitor, wherein the wiring terminal comprises at least two bolt electrodes, and the main body of capacitor comprises a tubular shell, an upper cover and a capacitor core which is positioned in the tubular shell. By adopting the embodiment of the utility model, a cable conductor and the electrode contacts of the capacitor can be connected more firmly, and electric sparks can be prevented at the position of a connecting position. The wiring terminal is also provided with a protective cover which can avoid electric shock. The tail part of the wiring terminal is a rod-shaped conductive metal; when the capacitor loses effectiveness, the upper cover bulges, and the rod-shaped conductive metal and the capacitor core are pulled to be disconnected and quickly cut off the circuit, thereby playing the role of preventing explosion. The tail parts of the bolt electrodes are rod-shaped conductive metals with larger diameter, which can withstand high current.
Description
Technical field
The utility model relates to electric elements, relates in particular to a kind of capacitor with bolt electrode nipple.
Background technology.
What cylindrical low voltage parallel capacitor in the market all adopted is the compression joint type leading-out terminal, and its mode of connection is to compress cable to link to each other with circuit.This mode of connection is loosening easily, electric spark will occur at the electrode connection place during energising, causes binding post to burn, and capacitor was lost efficacy, and can also cause fire when serious, burns electric equipment.The electrode nipple of capacitor is exposed to the outside and causes that easily people get an electric shock because of carelessness.
Traditional in addition lead is broken the capacitor of the explosion-proof mode of type, when capacitor lost efficacy, is not easy fast and accurately capacitor to be left from circuit interruption, avoids danger such as short circuit, blast, does not also allow big electric current to pass through simultaneously.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model embodiment provides a kind of capacitor with bolt electrode nipple, and it is more firm that cable is connected with the electrode for capacitors joint, prevents electric spark in wiring place.
The utility model embodiment provides a kind of capacitor with bolt electrode nipple, and it comprises binding post and capacitor main body, and wherein said binding post comprises at least 2 bolt electrodes; Described capacitor main body comprises cylindrical case, loam cake and is arranged in the capacitor body of described cylindrical case.
Further, the projection or the groove of indication wiring polarity arranged on described binding post, be convenient for people to correctly connect cable.
Further, also have a protective cover on the described binding post, be used for protection against electric shock.
Further, described bolt electrode nipple afterbody is shaft-like conducting metal, when described capacitor inefficacy loam cake is heaved, can be connected with described capacitor body automatic disconnection, plays explosion-proof effect.Described bolt electrode nipple is the thicker shaft-like conducting metal of diameter, can bear big electric current.
Adopt the utility model embodiment, it is more firm that cable is connected with the electrode for capacitors joint, prevents electric spark in wiring place.
Also have a protective cover on the described binding post, be used for protection against electric shock.Described bolt electrode afterbody is shaft-like conducting metal, and when described capacitor inefficacy, when loam cake was heaved, the pulling electrode can be connected fast cut-off circuit with the capacitor body automatic disconnection.
Described bolt electrode afterbody joint is the thicker shaft-like conducting metal of diameter, can bear big electric current, connects more powerful load.

Fig. 2 is a kind of three-phase low voltage parallel capacitor vertical view with bolt electrode nipple that the utility model embodiment provides.
Embodiment
For making this purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model embodiment provides a kind of three-phase low voltage parallel capacitor with bolt electrode nipple, it comprises binding post 1 and capacitor main body, and wherein said capacitor main body comprises cylindrical case 2, loam cake 3, explosion-proof 4 and is arranged in the capacitor body 5 of described cylindrical case.
The utility model adopts the screw bolt-type mode of connection, during use cable is linked to each other with a wiring clamp, and the wiring clamp is enclosed within on the bolt, tightens with spring shim 6 and nut 7.This mode of connection wiring is firm, is electrically connected reliably, can prevent effectively that terminal from burning phenomenon.
Also have a protective cover 8 on the described binding post, be used for protection against electric shock.Described bolt electrode nipple is shaft-like conducting metal, and when capacitor lost efficacy, internal pressure increased, and loam cake is heaved, and shaft-like conducting metal can be connected with described capacitor body automatic disconnection, and fast cut-off circuit is avoided danger such as short circuit, blast.Break the explosion-proof mode of type with traditional lead and compare, this explosion-proof mode is more reliable, and the needed pressure of explosion-proof startup can be adjusted as required.
Described bolt electrode nipple afterbody can bear big electric current and pass through for the thicker shaft-like conducting metal of diameter.
As shown in Figure 2, the projection or the groove 9 of indication wiring direction arranged on the described binding post 1, indication wiring direction is convenient for people to connect cable.
Certainly the capacitor for the various models that two electrode nipples are arranged also can adopt said structure, all belongs to protection range of the present utility model.
The above is a preferred implementation of the present utility model; certainly can not limit the interest field of the utility model with this; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement and change, these improvement and change also are considered as protection range of the present utility model.
