Description
Technical field
It the utility model is related to a kind of brush DC switch.
Background technology
In existing brush DC switch the circuit board with heater element due to its it is complicated in assembling it is more difficult enter
Row quickly installation assembling, after installation also because assembling the reason for fault rate it is higher, so as to cause the use of user into
This is higher, simultaneously as the caloric value of heater element is larger, existing circuit board is because structure is more unreasonable, its effect that radiates
Fruit is poor, thus also many is difficult to solve the problems, such as, for example radiating effect difference is caused overall under the conditions of working long hours
Heater element is continuously in the condition of high temperature, and then continues prolonged work at high operating temperatures, and integrated circuit plate module is easy
Break down, it is higher so as to the fault rate of global switch.
The content of the invention
The purpose of this utility model is that providing a kind of low brush DC of simple, good heat dissipation effect, fault rate that assembles opens
Close.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：A kind of brush DC switch, including
Pedestal, heater element, circuit board, spacing body and the fin with electrical connection, the circuit board are installed in pedestal, circuit
Plate opposite base is outwardly directed to be provided with several heater elements.
Further, through several through holes coordinated with heater element are provided with the spacing body, spacing body lid is connected to circuit
Top surface makes heater element expose to top surface on spacing body and circuit board is limited in pedestal on plate, and the fin is located on spacing body
Top surface simultaneously contacts with exposed heater element.
Further, the heater element is metal-oxide-semiconductor, and the circuit board with electrical connection passes through hard wire or soft
Electric wire connects.
The beneficial effects of the utility model are：Compared to existing brush DC switching technique, the utility model pass through by
Heater element is outwards installed on circuit board, and is coordinated using spacing body and circuit board, and the assembling for greatly reducing global switch is difficult
Degree, meanwhile, heater element it is exposed and be directly attached with fin the unique design of radiating also improve global switch dissipate
Hot property, switch failure failure is reduced while accelerating the operating temperature of global switch after radiating in compared with low state
Rate, it is excellent that the utility model has that assembly difficulty is low, speed is fast, good heat dissipation effect, fault rate are low etc. on the basis of existing technology
Point.
Brief description of the drawings
Fig. 1 is a kind of configuration schematic diagram of brush DC switch.
The parts title of numbering expression is as follows in accompanying drawing：1st, pedestal；2nd, heater element；3rd, circuit board；4th, spacing body；5th, dissipate
Backing；9th, through hole.
Embodiment
In order that obtaining the technological means that the utility model is realized, character of innovation is apparent to function, below will be further
Illustrate the utility model.
As shown in figure 1, a kind of embodiment of the utility model brush DC switch, including pedestal 1, heater element 2, have
Circuit board 3, spacing body 4 and the fin 5 of electrical connection, the circuit board 3 are installed in pedestal 1, the opposite base 1 of circuit board 3
It is outwardly directed to that several heater elements 2 are installed.
Opposite base 1, which outwards installs heater element 2 this unique design, in the utility model makes monoblock circuit board 3 and spacing body
4 cooperation is more simple, so as to which assembly difficulty is lowered, in addition, the heater element 2 outwards installed also increases integrated circuit plate
The area of dissipation of 3 heater elements 2, radiating effect compared with the prior art is more preferable, is effectively improved heater element 2 under running conditions
Heat condition, reduce the fault rate of integrated circuit plate 3, user also reduced while manufacturing enterprise's production cost is reduced
Working service cost.
The present embodiment can carry out convenient installation assembling for realization, reduce assembly difficulty, be provided with if running through on spacing body 4
The dry through hole 9 coordinated with heater element 2, spacing body 4 are covered to be connected to top surface on circuit board 3 and make heater element 2 expose on spacing body 4 and pushed up
Circuit board 3 is simultaneously limited in pedestal 1 by face, and the fin 5 is located at top surface on spacing body 4 and contacted with exposed heater element 2,
Spacing body 4 not only ensures that electric leakage electric conduction phenomena will not occur with fin 5 for the internal circuit of pedestal 1, also that circuit board 3 is spacing in pedestal
In 1, make it that upper and lower and horizontal direction movement will not occur, ensure the connective stability of global switch, and then further lifted
The service life of global switch, the heater element 2 are metal-oxide-semiconductor, are directly that the fin 5 that metal-oxide-semiconductor contacts makes with heater element 2
The metal-oxide-semiconductor obtained on circuit board 3 is more effectively radiated, and further reduces the temperature of metal-oxide-semiconductor, reduces the feelings of its failure
Condition, influence of the metal-oxide-semiconductor of higher temperature to circuit board and global switch is also alleviated, enable global switch for a long time in stable
Worked under state, the connected mode that the circuit board 3 with electrical connection is connected by hard wire or cord is needing
It can flexibly be used according to actual conditions during the electric wire of differing texture, avoid the switch of singular association form from bringing when in use
Inconvenience.
Although the utility model is disclosed as above with specific embodiment, but it is not limited to the utility model, appoints
What those skilled in the art, in the case where not departing from spirit and scope of the present utility model, can still make a little change with
Retouching, therefore the scope of protection of the utility model should be defined depending on the scope institute defender of appended claims.
