Description

The power supply of d.c. motor draws tipping and puts

Technical field

The utility model relates to supply unit, and the power supply that especially a kind of convenient location reaches the d.c. motor that can not be torn draws tipping and puts.

Background technology

See also the heat emission fan 90 of first kind of known tool d.c. motor shown in Figure 6, the power line 92 of this heat emission fan 90 is drawn by stator coil 91 and connects, and the frame 93 of pile warp housing is drawn with resistance body 94 backs, so, outside from frame 93 to the strength of pullling of this power line 92, can absorb by this frame 93 and resistance body 94, therefore can prevent that this power line 92 from got loose being connected of 91 of power line 92 and stator coils because of pullling.

In addition, ask for an interview shown in Fig. 7,8, it is second kind of known heat emission fan 80, the power line 82 of this heat emission fan 80 is drawn by stator coil 81 and connects, this power line 82 is also drawn by the wall 85 that the depression bar 84 of a cover plate 83 presses the pile warp housing again, so, outside from heat emission fan 80 housings to the strength of pullling of this power line 82, can also absorb by the wall 85 of this depression bar 84 and housing, because of being pullled got loose being connected of 81 of power line 82 and stator coils to prevent this power line 82.

Press, the heat emission fan of above-mentioned known use d.c. motor, the drawing of its power line connects design and mainly utilizes the protruding framework that is exposed to of tiny line body to draw and connect power supply outward, therefore, nationality absorbs the strength that this power line is pullled by the wall 85 of this frame 93 and resistance body 94 or depression bar 84 and housing, come off to prevent that this power line from being pullled, only this commonly uses the heat emission fan of using d.c. motor, it is to prevent to draw the power line that connects to be pullled and loosen in the manufacturing inconveniently, and it also has and draws that the power line that connects is protruding to be exposed to outer situation not attractive in appearance.

Summary of the invention

The purpose of this utility model is to address the above problem, and draws tipping with the power supply that a kind of d.c. motor is provided and puts, and this device can make things convenient for processing and manufacturing, and it draws the electric source structure that connects and has preferred positioning and can not be torn.

The power supply of d.c. motor of the present utility model draws tipping to be put, and comprises a housing, establishes the circuit board combination that axle bed supplies stator and is provided with drive circuit by base plate, and this stator is with the rotation axis hinge joint rotation of central siphon for rotor, and housing is tool one outer wall at least; An and power panel, this power panel is located at the outer wall of housing, tool draws connection circuit, this draws the driving loop that connection circuit one end is electrically connected at the rotation of control motor starting, drawing connection circuit one end establishes to draw and connects the end pin, this draws and connects the end pin and can connect power supply and rotate for motor driven for drawing, draw connection circuit in addition end be connected in drive circuit on the circuit board.

Structure of the present utility model, this d.c. motor or use the heat emission fan of this d.c. motor not have the protruding outer power supply lead wire of housing that is exposed to, and more not having power supply lead wire is pulled apart the facts that falls and is taken place, so, the manufacturing fraction defective of this d.c. motor can reduce, and the outward appearance of motor also can be simpler attractive in appearance, and this d.c. motor or heat emission fan are also comparatively convenient when using or depositing again.

Embodiment

Please read shown in Figure 1, its the utility model first preferred embodiment, this motor 1 is established tubule 14 combinations of axle bed 12 for stator 13 by the base plate 11 of a housing 10,14 rotation axiss 16 for rotor 15 of this central siphon articulate rotation, again, the outer wall of this housing 10 is provided with a power panel 2, these power panel 2 tools draw connection circuit 21, an end that draws connection circuit 21 for connecing one of power supply and draw and connect end pin 22 for drawing, the other end that draws connection circuit 21 then is electrically connected at the circuit board 131 (asking for an interview Fig. 3) with drive circuit, the power panel 2 of utility model can form by same flexible cord substrate with circuit board 131 in the middle of preferred embodiment, in addition, housing 10 outer walls more can be provided with a caulking groove 17, can power source plate 2 of this caulking groove 17 embeds the location, and in case of necessity, the base plate 11 of this housing 10 has a ringwall 111, this ringwall 111 is provided with short slot 112, and this short slot 112 can pass through for drawing connection circuit 21.

Please see Figure 2, shown in 2, it is the combination situations of this first embodiment, the circuit board 131 of this motor 1 is connected with the connection circuit 21 that draws of power panel 2, and this draws the base plate 11 set short slots 112 that connection circuit 21 passes through housing 10, and, this power panel 2 can be embedded in the caulking groove 17 interior one-tenth location of housing 10, and connecing end pin 22 by these power panel 2 set drawing can do connecing of power supply and establish, so the circuit board 131 of the tool drive circuit of this motor 1 electrically connects with the connection circuit 21 that draws of power panel 2, and this power panel 2 is embedded in the caulking groove 17 interior one-tenth location of housing 10 outer walls, therefore, this motor 1 does not promptly have the protruding power line that is exposed to outside the housing 10, does not more have power line and is pullled the facts of breaking.
