Description

A kind of long-life type capacitor

Technical field

The utility model is related to a kind of capacitor, particularly a kind of long-life type capacitor.

Background technology

Capacitor, usually referred to as it accommodates the ability of charge as capacitance, is represented with letter C.Capacitor is in electronic equipment One of electronic component largely used, the separated by direct communication being widely used in circuit couple, and bypass, filtering, resonant tank, energy Amount conversion, control etc..

In existing capacitor, capacitor main body is wrapped in a shell with closed chamber, and this sets The mode of putting can lead to the generation of a problem：Capacitor main body can generate heat when working, and above-mentioned structure can lead to radiating rate More slowly, service life and the job stability of capacitor are influenced.

Utility model content

The purpose of this utility model is that there are the above problems for existing technology, it is proposed that a kind of long-life type capacitor, The technical issues of solution is how to prolong the service life.

The purpose of this utility model can be realized by following technical proposal：A kind of long-life type capacitor, including shell, sets In the fuse in shell and in shell and the positive outside wire and negative outside wire that are connected with fuse, positive outside wire Shell is stretched out with the upper end of negative outside wire, embedding layer is formed by epoxy resin encapsulated between the shell and fuse, It is characterized in that, the top of the shell is opened wide, and the position of outer casing top surface is higher than the position of embedding layer top surface, the shell Side wall on through offering multiple inclined holes, and each inclined hole is respectively positioned between embedding layer and outer casing top surface；The inclined hole position It is less than the position for the port that inclined hole is located on outer side wall in the position of the port on housing interior side-wall.

In use, capacitor is reverse mounted on circuit boards.

It is in open state by the top setting of shell, while heat dissipation area is improved, and reduces the obstruction flowed to gas, So as to accelerate distributing for capacitor internal heat, so as to extend the service life of this capacitor；Secondly, it sets and runs through on side wall of outer shell Inclined hole, and inclined hole is between embedding layer and housing top, further to increase heat dissipation area, so as to further extend this electricity The service life of container.

Inclined hole, in setting obliquely, can effectively hinder the impurity such as dust to enter inclined hole in this way after capacitor installs It is interior, stablize the purpose of extension capacitor life-span and realize.

In above-mentioned long-life type capacitor, the aperture of the inclined hole is 0.5cm~0.8cm.

In above-mentioned long-life type capacitor, there is the rib that annularly protrudes on the inner wall of the shell, rib and Shell is coaxially disposed and the two is an integral structure, and the inclined hole is between rib and embedding layer.Under the blocking of rib, The flow direction of changing section heat makes this partial heat be discharged by inclined hole, can reduce the heat of convergence on circuit boards in this way Amount, to improve the job stability of circuit board.

In above-mentioned long-life type capacitor, the madial wall of the rib is tapered, and the internal diameter of rib is gradual downwards Reduce.Using above-mentioned design, guide functions are risen to the heat discharged by cover top portion, make the heat of capacitor internal faster The discharge of speed.

Compared with prior art, this long-life type capacitor has the following advantages：

1st, the setting of the top of shell while heat dissipation area is improved, and is reduced into the resistance flowed to gas in open state Hinder, so as to accelerate distributing for capacitor internal heat, so as to extend the service life of this capacitor；Secondly, it is set on side wall of outer shell Perforative inclined hole, and inclined hole is between embedding layer and housing top, further to increase heat dissipation area, so as to further extend The service life of this capacitor.

2nd, inclined hole can effectively hinder the impurity such as dust to enter tiltedly in this way in setting obliquely after capacitor installs In hole, stablize the purpose of extension capacitor life-span and realize.

Specific embodiment

It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.

As depicted in figs. 1 and 2, this long-life type capacitor is by shell 1, fuse 2, positive outside wire 3, negative outside wire 4, filling 5 grade of sealing forms.

Wherein, shell 1 is in tubbiness, and the top and bottom of shell 1 are respectively in unlimited and closed.Fuse 2 is set on shell 1 It is interior；Positive outside wire 3 and negative outside wire 4 are set in shell 1 and are connected with fuse 2, and positive outside wire 3 and cathode are drawn The opening that the upper end of line 4 both passes through 1 top of shell is extend out to outside shell 1.

Embedding layer 5 is formed by epoxy resin encapsulated between shell 1 and fuse 2, and at this point, the position of 1 top surface of shell is higher than The position of 5 top surface of embedding layer.Multiple inclined hole 1a are offered as shown in Fig. 2, running through on the side wall of shell 1, and each inclined hole 1a is equal Between 1 top surface of embedding layer 5 and shell；The position that inclined hole 1a is located at the port on 1 madial wall of shell is located at less than inclined hole 1a The position of port on 1 lateral wall of shell.In the present embodiment, the aperture of inclined hole 1a be 0.5cm~0.8cm, and preferably this Aperture is 0.6cm.

Further illustrate there is the rib 1b annularly protruded, rib 1b and shell 1 are coaxially disposed on the inner wall of shell 1 And the two is an integral structure, at this point, inclined hole 1a is between rib 1b and embedding layer 5.Further, the inside of rib 1b Wall is tapered, and the internal diameter of rib 1b is gradually reduced downwards.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
