Abstract

The utility model relates to a capacitor wiring terminal, comprising three layers which are a base layer, a copper layer and a tin layer, wherein the tin layer is arranged on the copper layer, and the base layer, the copper layer and the tin layer are pressed against each other to form an integral whole. The capacitor wiring terminal provided by the utility model has the advantages that the wiring terminal is designed to be of three layers which are the base layer, the copper layer and the tin layer, the base layer, the copper layer and the tin layer are mutually pressed together and not easy to break away from each other after being pressed, the oxidation resistance is strong, and the service life is prolonged, thereby prolonging the service life of a capacitor applying the capacitor wiring terminal provided by the utility model.

Description

Capacitor terminal

Technical field

The utility model relates to capacitor technology field, relates in particular to capacitor terminal.

Background technology

Capacitor is commonly referred to electric capacity, and electric capacity is also called " capacitance ", refers to the electric charge reserves under given potential difference, is designated as C, and international unit is farad (F).In general, electric charge is understood stressed and is moved in electric field, has had medium between conductor, has hindered electric charge move and make charge accumulation on conductor, causes the accumulation of electric charge to store, and the quantity of electric charge of storage is called electric capacity.Electric capacity is one of a large amount of electronic components that use in electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.

In prior art, the oxidation resistance of the binding post of capacitor is very poor, after long-time use, easily causes binding post conduction not smooth, has a strong impact on the useful life of capacitor.

Utility model content

In view of this, be necessary to provide the capacitor terminal that a kind of oxidation resistance is strong sub.

The utility model is achieved in that capacitor terminal, comprises three layers, is respectively basic unit, copper layer and tin layer, and described copper layer is located in basic unit, and described tin layer is located on copper layer, and described basic unit, copper layer and tin layer are laminated into whole.

The advantage of capacitor terminal that the utility model provides is: binding post is designed to three layers, be respectively basic unit, copper layer and tin layer, and be laminated together, after pressing, be difficult for departing from, and antioxygenic property is strong, increase the service life, thereby extended useful life of the capacitor that uses the utility model capacitor terminal.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model capacitor terminal.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Refer to Fig. 1, Fig. 1 is the structural representation of the utility model capacitor terminal.

Described capacitor terminal, comprises three layers, is respectively basic unit 10, copper layer 20 and tin layer 30, described copper layer 20 is located in basic unit 10, and described tin layer 30 is located on copper layer 20, and described basic unit 10, copper layer 20 and tin layer 30 are laminated into whole, outermost layer is tin layer 30, is convenient to the docking scolding tin in later stage.

Binding post is designed to three layers, be respectively basic unit 10, copper layer 20 and tin layer 30, and be laminated together, after pressing, be difficult for departing from, and antioxygenic property is strong, through salt mist test repeatedly, prove, its anti oxidation time can reach 72 hours, binding post is extended useful life, thereby extended the useful life of the capacitor that uses the utility model capacitor terminal.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.

Claims

1. capacitor terminal is sub, it is characterized in that, comprise three layers, be respectively basic unit (10), copper layer (20) and tin layer (30), described copper layer (20) is located in basic unit (10), it is upper that described tin layer (30) is located at copper layer (20), and described basic unit (10), copper layer (20) and tin layer (30) are laminated into whole.
