Abstract
The utility model discloses a kind of end cap for micro motor, comprise one for the end face that is connected with stator module and a bottom surface of arranging for fixed terminal, described bottom surface is provided with brush mouth, brush assembly of electric is provided with in brush mouth, described bottom surface is provided with square groove, and described square groove is connected to the brush mouth on end cap bottom surface for fixing also positioning lead.The utility model connects electric mode by adding the conventional terminal of the structural change of square groove in end cap bottom surface, can ensure the tension destructive power intensity after wire bonds, and after wire is bent, the risk of open circuit reduces greatly.Certain adhesion is had everywhere when thin-wall construction can ensure that end cap and motor case assemble.Boss structure is to ensure that end cap and motor remain on a fixed-direction when assembling substantially, and the magnetic field of motor can maintain a constant level, ensures the stable of product quality.
Description
Technical field
The utility model relates to field of motors, particularly relates to a kind of end cap for micro motor.
Background technology
Vibrating motor is mainly used in mobile phone, Smart-watch, on the electronic product such as bluetooth equipment, PAD, Notebook, works the function of vibrating alert of mourning in silence.The oblate pillar shell of tradition and full closed attachment support, the structure of end cap is that after using terminal soldering, motor is welded by SMT again.This kind of assembling mode has certain requirement to the scale of factory building and equipment, and infusion of financial resources amount is large.
Utility model content
The purpose of this utility model be to provide a kind of can realize wire bonds after and can the micro motor end cap of proof strength.
For achieving the above object, the utility model adopts following technical scheme:
A kind of end cap for micro motor, comprise one for the end face that is connected with stator module and a bottom surface of arranging for fixed terminal, described bottom surface is provided with brush mouth, brush assembly of electric is provided with in brush mouth, described bottom surface is provided with square groove, and described square groove is connected to the brush mouth on end cap bottom surface for fixing also positioning lead.
In technique scheme, the surrounding of described end cap bottom surface is provided with thin-walled, and described thin-walled has tensile force.
In technique scheme, described square groove is two, and the mode along the axis symmetry of end cap body is arranged on bottom surface.
In technique scheme, the top edge place of described end cap is provided with positioning boss.
In technique scheme, described end cap bottom surface is provided with two brush mouths, inserts brush assembly of electric in brush mouth, two brush assembly of electric be 180 degree symmetrical.
In technique scheme, two wires, are independently navigated to brush mouth by a square groove separately, are connected with the brush assembly of electric in brush mouth.
The beneficial effects of the utility model: connect electric mode by adding the conventional terminal of the structural change of square groove in end cap bottom surface, can ensure the tension destructive power intensity after wire bonds, after wire is bent, the risk of open circuit reduces greatly.Certain adhesion is had everywhere when thin-wall construction can ensure that end cap and motor case assemble.Boss structure is to ensure that end cap and motor remain on a fixed-direction when assembling substantially, and the magnetic field of motor can maintain a constant level, ensures the stable of product quality.
Accompanying drawing explanation
Fig. 1 is the top surface structure schematic diagram of utility model end cap;
Fig. 2 is the bottom surface structure schematic diagram of utility model end cap;
Wherein: 1 is square groove, 2 is brush mouths, and 3 is brush assembly of electric, and 4 is thin-walleds, and 5 is boss.
Embodiment
As shown in Figure 1, end cap of the present utility model and traditional end cap have obvious difference, are just on the end face of end cap, be provided with two square grooves, and the effect of direction groove is exactly for connecting the location of wire and fixing.Connect wire through square groove, to be located by square groove and after being fixed to brush mouth position, after brush inserts from the position of brush insert port and conductive contact, re-use welding procedure and wire and brush are firmly fixed.
As shown in Figure 2, end cap is provided with brush mouth, two brush opening's edge end cap central positional symmetry in the utility model are arranged, in brush mouth, brush assembly of electric is installed, brush is inserted by two prescription brush mouths, keeps intimate-association state with end cap after brush press-in, and corresponding detection guarantee brush is done to release power do not depart from.It is symmetrical in 180 degree after two brushes insert.
Also being provided with thin-walled in the bottom surface surrounding of end cap; thin-walled itself has tensile force; outwards discharge elastic force when being squeezed; therefore when semi-finished product connect at needs; thin-walled just plays the effect of a buckle; can not drop easily when making end cap be connected with other connectors, also facilitating the connection to brush and wire simultaneously.And traditional technique is all install that brush is just direct to be fixedly connected with end cap with other connectors, inconvenient follow-up detection is according to repetition operation.
The bottom surface of end cap is also provided with boss, and the effect of boss is for the location to end cap, makes end cap install corresponding installation direction and is connected with other connectors, avoids occurring connecting by mistake, ensures that the magnetic field in motor is same direction.
All features disclosed in this specification, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
