Abstract

A multi-terminal capacitor relates to the technical field of capacitor; the multi-terminal capacitor comprises a capacitor housing; more than one set of capacitor banks are contained in the capacitor housing; each capacitor bank is provided with an independent leading-out terminal; and the capacitor banks are provided with a common leading-out terminal; the independent leading-out terminals and the common leading-out terminal are all led out by binding posts; and the multi-terminal capacitor is characterized in that the common leading-out terminal is commonly formed by more than one binding posts, and the binding posts are connected by a copper bar. The leading-out terminals employ a structure of a plurality of separate binding posts, and each binding post and the independent leading-out terminal have same structures and sizes, so the capacitor can be led out by using same kind of cables; and the binding posts of the common leading-out terminal is more than one in number, so connection of the cables is convenient.

Description

The multiterminal sub-capacitor

Technical field

The utility model relates to the capacitor technology field, is specifically related to the capacitor that public exit was drawn and had to a kind of multiterminal.

Background technology

Exist a plurality of capacitor groups to be placed on the interior capacitor of a shell in the market, each capacitor group has an independent exit, and has a public exit.If the quantity of capacitor internal capacitor group is more, public exit has converged the electric current of a plurality of capacitor groups, needs the summation by a plurality of capacitor group electric currents, should have bigger sectional area, and its size should be greater than independent exit.But public exit and independent exit size are inconsistent, draw when installing at electrode for capacitors, need to prepare the different cables of drawing, and a plurality of exit cables are drawn also and can be with inconvenience on public exit.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of current capacity that can improve the public exit of capacitor, is convenient to the multiterminal sub-capacitor of extraction electrode again.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of multiterminal sub-capacitor, comprise a capacitor case, described capacitor case inside accommodates one group of above capacitor group, each capacitor group has an independent exit, and have a public exit, described independent exit and public exit are binding post and draw, and it is characterized in that: described public exit is that the binding post more than is formed jointly, connects with copper bar between each binding post.

Many binding posts of described public exit do not use copper bar to connect, and connect with lead in capacitor case inside, and the outside does not connect, and the structure of all binding posts is all identical with size.

The binding post quantity of described public exit is two.

The quantity of described independent exit binding post is five.

Described binding post is screw-rod structure.

Described binding post is the inner bolt hole structure.

The specification exit of capacitor can adopt the structure of a plurality of separation binding posts, the structure of each binding post and independent exit and consistent size, can use same cable when capacitor is drawn like this, and the binding post of public exit there are many, can make things convenient for the connection of cable.The number of binding post can be considered according to combined factors such as the quantity of capacitor, capacity, determines the ampacity of public exit, fixs suitable sectional area, and quantity can be two or more.

In order to be connected as a single entity between the binding post that guarantees public exit, many binding post intercolumniations are used lead and are connected, as connecting at the outside copper bar that uses of capacitor.

The beneficial effects of the utility model are: the utility model exit adopts the structure of a plurality of separation binding posts, the structure of each binding post and independent exit and consistent size, can use same cable when capacitor is drawn like this, and the binding post of public exit has many, can make things convenient for the connection of cable.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1 and Figure 2, a kind of multiterminal sub-capacitor, comprise a capacitor case 4, capacitor case 4 inside hold by a plurality of capacitor groups, each capacitor group has an independent exit 1, and has a public exit 2, and independent exit 1 and public exit 2 are binding post and draw, public exit 2 is that the binding post more than is formed jointly, connects with copper bar 3 between each binding post.

Being connected at the outside copper bar that adopts of capacitor between public exit 2 binding posts connects, also can not adopt this connected mode, and at the inner lead that uses of capacitor each binding post of public exit is coupled together, and the structure of all binding posts is all identical with size.

The binding post quantity of public exit is two, and the quantity of independent exit binding post is five.According to quantity and the capacity of capacitor internal capacitor group, the binding post quantity of public exit 2 can surpass two, and the quantity of independent exit 1 is consistent with the quantity of capacitor internal capacitor group.The structure of binding post is screw-rod structure, also can use other structure that screw etc. can extraction electrode.

Fig. 3 is electrical connection diagram of the present utility model, and a plurality of capacitor groups have independent exit A, B, C, D, E etc. respectively, have public exit N simultaneously.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
