Abstract

The utility model relates to a capacitor which is matched with compressors in various widow type, chest type and divided air conditioners. The utility model is characterized in that a core group (2) whose both ends are respectively welded with lead-out wires (11, 12) is arranged in an aluminium housing (1) which in a straight barrel shape, and one lead-out wire (12) which is easy to break is welded on the bottom of the core group (2) through a plastic core shaft which is arranged in the center of the core group (2); a pressure tank (7) is engraved on the upper end of the aluminium housing (1), and the lead-out wires (11, 12) at both ends of the core group (2) penetrate through a shim plate cover (4) and a sealing cover (8) and then are soldered on two lead-out terminals (9) by using aluminium-tin solder (10). The utility model has the advantages of small size, low cost, low price, and the explosion-proof function.

Description

Capacitor for air-conditioner

The utility model relates to and a kind ofly is the matching used capacitor of compressor in all kinds of window formulas, the cabinet type and separate type air conditioner, but its starting motor and improve the operational effect of motor.

Air conditioner is big with the power of capacitor, the service condition harshness.Use in refrigeration system capacitor in the past is many to the quality and the consideration in useful life of its electrical property, but consider very few for the capacitor safety in utilization, so that early failure (puncture, short circuit) appears in the capacitor in the air conditioner that has, thereby cause the capacitor increase in temperature, cause exploding, the danger of fire.

The purpose of this utility model is to provide a kind of use in refrigeration system capacitor with explosion prevention function, security of operation.

The utility model is to realize like this, always the tube the aluminium shell in a core group is housed, lead-out wire is welded at the two ends of core group respectively, and wherein an easily broken lead-out wire is welded on core group bottom by core group switching centre plastics mandrel, and the thickness at its easily broken position is 0.15 ± 0.02mm; Embedding ground is cured on the core group, and cured top, ground is the backing plate lid, equal liner insulating paper in the inwall of aluminium shell and bottom and bottom; Indent is carved with in the upper end of aluminium shell, and the top is provided with seal cover, and two leading-out terminals are arranged on the seal cover, and the lead-out wire at core group two ends passes the backing plate lid and seal cover is welded on two leading-out terminals with plumber's solder.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is a structural representation of the present utility model.

Always the tube aluminium shell (1) in a core group (2) is housed, lead-out wire (11,12) is welded at the two ends of core group (2) respectively, wherein an easily broken lead-out wire (12) is welded on core group (2) bottom by core group (2) center plastics mandrel, and the thickness at its easily broken position is 0.15mm; Core group (2) goes up embedding ground cured (3), and ground cured (3) top is backing plate lid (4), equal liner insulating paper in the inwall of aluminium shell (1) and bottom (5) and bottom (6); Indent (7) is carved with in aluminium shell (1) upper end, the top is provided with seal cover (8), two leading-out terminals (9) are arranged on the seal cover (8), and the lead-out wire (11,12) at core group (2) two ends passes backing plate lid (4) and seal cover (8) is welded on two leading-out terminals (9) with plumber's solder (10).

When short trouble appearred in capacitor, its internal temperature increased severely, and internal pressure increases; at this moment, deformation---it is elongated to stretch in indent (7) generation of capacitor aluminium shell (1) upper end, and the easily broken lead-out wire (12) in the capacitor is broken; make capacitor open-circuit, thereby play a protective role.

Little, the dependable performance of this small product size, there is the safety anti-explosive structure capacitor inside, and does not contain the poisonous impregnated material of trichloro biphenyl and so on, so cost is low, low price, economic benefit height.

Claims

1, a kind of use in refrigeration system capacitor, it is characterized by always the tube aluminium shell (1) in a core group (2) is housed, lead-out wire (11,12) is welded at the two ends of core group (2) respectively, and wherein an easily broken lead-out wire (12) is welded on core group (2) bottom by core group (2) center plastics mandrel; Core group (2) goes up embedding ground cured (3), and ground cured (3) top is backing plate lid (4), equal liner insulating paper in the inwall of aluminium shell (1) and bottom (5) and bottom (6); Indent (7) is carved with in aluminium shell (1) upper end, the top is provided with seal cover (8), two leading-out terminals (9) are arranged on the seal cover (8), and the lead-out wire (11,12) at core group (2) two ends passes backing plate lid (4) and seal cover (8) is welded on two leading-out terminals (9) with plumber's solder (10).

2, use in refrigeration system capacitor according to claim 1, the thickness that it is characterized by its easily broken position of easily broken lead-out wire (12) is 0.15 ± 0.02mm.
