The phase winding of printed circuit board (PCB) and brshless DC motor all is to be connected with the form of welding when brshless DC motor is now manufactured.Though this method of attachment can guarantee printed circuit board (PCB) and motor windings reliable be connected and the junction signal of telecommunication can be good passes through, but this method of attachment must be placed pad on the opposite side circuit board of paster Hall element, be used for welding the winding of motor, so printed circuit board (PCB) must be designed to double sided board, increased the manufacturing cost of printed circuit board (PCB).All need artificial welding when the assembling of printed circuit board (PCB), increased manpower and technology cost, production efficiency is low.When the electrical machmary maintenance disassemble printed circuit board, need manually the scolding tin sucking-off of solder joint, could dismantle printed circuit board (PCB) down, the batch jobs when being not suitable for maintenance of motor.
Therefore, existing brshless DC motor circuit board method of attachment exists disadvantages such as production cost height, dismounting process complexity when motor is manufactured.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved, and a kind of brshless DC motor and circuit board quick connecting device are provided.For this reason, the utility model is taked following technical scheme:
Brshless DC motor and circuit board quick connecting device, it is characterized in that: it comprises the conductive pin that is electrically connected with motor windings, the connector that is fixed in circuit board that cooperates with contact pin, but described connector comprises the metal clips of a plurality of clamping contact pins, and described shell fragment is electrically connected with circuit board.Contact pin inserts the connector that cooperates with it, react on contact pin after the shell fragment distortion, with the contact pin clamping, realize both connections, the shell fragment contact pin is detachable the connection with connector, contact pin and connector are pegged graft and are realized being electrically connected of winding and circuit board, abandoned the connected mode of manual welding, the pad that makes the another side of paster Hall element printed circuit board (PCB) be used for the phase winding welding can remove, but in the printed circuit board (PCB) single face cabling fabric swatch of paster Hall element one side, the manufacturing cost of having saved printed circuit board (PCB); And,, still when repair demolition, adopt this pull-plug device can effectively improve pipelining efficient no matter assemble in the body and the printed circuit board (PCB) production of brshless DC motor.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
A plurality of shell fragments are combined to form up-small and down-big grafting chamber.The afterbody in up-small and down-big grafting chamber is than the wide insertion of being convenient to contact pin of head, and narrower head chucking power is big, the contact pin reliable clamping.
Described connector is established the Connection Block of hollow, and described contact pin is strip, head tool oblique angle; Shell fragment is symmetrically set in the left and right sides of Connection Block; Described Connection Block also can be ringwise, described contact pin cylindricality, and head tool cone angle, the shell fragment arc equidistantly is arranged on the annular Connection Block.The contact pin at head tool oblique angle, the contact-making surface in itself and horn mouth grafting chamber is big, and chucking power is big, and it is reliable to peg graft.
Described connector is established four shell fragments, and four shell fragments are divided into the left and right sides of Connection Block.Two shell fragments are respectively arranged about Connection Block, and two shell fragments side by side have the function of automatic alignment pin position, and contact is good, connection is reliable.
The described connector outside is provided with locating part, and described locating part comprises the holder of being located at shell fragment outside banking stop and linking to each other with the banking stop lower end.Banking stop is used to strengthen shell fragment, increases the chucking power to contact pin, plays the distortion of restriction shell fragment simultaneously, avoids shell fragment because of being out of shape the generation of the situation that too much can't reset even fracture.
Described banking stop head bends inwards, and forms protruding contacting part.Make the contacting part of banking stop head to conflict with shell fragment, that reduces that form error etc. brings influences the stress problems of shell fragment to contact pin because of banking stop conflict position is different.
Described shell fragment is " 7 " shape, and it is higher than banking stop, is provided with the deformation space between shell fragment and the banking stop.The deformation space provides the deformation space of shell fragment, and the bending design of shell fragment can prevent to scratch.
The lower end of described Connection Block is provided with a plurality of welding contact pins, and the welding contact pin passes circuit board and is connected with circuit board by weld layer.
The whole conductive metallic material that adopts of described connector, the periphery of locating part is established insulating case.Circuit board line is by welding contact pin, Connection Block and shell fragment formation path, after contact pin and shell fragment touch, just can flow into motor windings through the contact by the circuit board electric current.
Beneficial effect: contact pin inserts in the grafting chamber that is combined by shell fragment that cooperates with it, react on contact pin after the shell fragment distortion, with the contact pin clamping, realize both detachable connections, reach the purpose that is electrically connected of winding and circuit board, abandoned the connected mode of manual welding, the pad that makes the another side of paster Hall element printed circuit board (PCB) be used for the phase winding welding can remove, but in the printed circuit board (PCB) single face cabling fabric swatch of paster Hall element one side, the manufacturing cost of having saved printed circuit board (PCB); And, help to improve production, assembling, maintenance efficiency.
