Abstract
The utility model relates to a framework with lock for fixing circuit board of motor, comprising a body unit and a locking unit. The locking unit comprises frames and a bottom plate of an integral structure, the body unit comprises an outer framework and a support fixed inside the outer framework, and the locking unit is connected with the body unit through the frames and the outer framework to form an integral structure. The frames of the locking unit are higher than the plane where the bottom plate is positioned, upper portions of the frames are provided with inwards extending locks, and the locks and the bottom plate coordinate to fix circuit boards. The framework with lock for fixing circuit board of motor is characterized by simple structure and convenient assembly, and can firmly fix circuit boards on the framework, and protect lead-out wires and enameled wires on circuit boards against direct forces.
Description
Technical field
The utility model relates to a kind of circuit board skeleton, specifically is used for fixing the skeleton of the button with lock of circuit board in motor.
Background technology
In the Circuits System of stepping motor, often all be to realize for the fixing of circuit board at present by the mode that pressing plate combines with screw, right this fixed form is not only installed trouble, take time and effort, and along with the long-time running of motor, integrate parts and also be prone to loosening and obscission, and then influence the normal operation of motor even can cause security incident; This in addition fixed form is not carried out unified integration and protection to lead-out wire and the enamelled wire that is welded on the circuit board, and safety, insulating properties are relatively poor, problem such as easily produce loose contact because of its root solder joint is directly stressed or come off; Therefore, the said fixing mode can not satisfy the demand in market.
Summary of the invention
The purpose of this utility model provides a kind of circuit board skeleton of button with lock, and lead-out wire on the protective circuit plate and enamelled wire solder joint are directly not stressed but it not only can be fixed on circuit board on the skeleton securely.
For solving the problems of the technologies described above, the technical scheme that the utility model is realized is: a kind of circuit board skeleton of button with lock, comprise body and sticking department, described sticking department comprises frame and the base plate with integrative-structure, described body comprises outside framework and the support that is connected the outside framework inboard, and described sticking department and body constitute integrative-structure by the binding of frame and outside framework; Described sticking department frame is higher than plane, base plate place, and frame top also is provided with to the inside the snap close that extends, by this snap close and cooperating of base plate circuit board being fixed.
Further improvement of the utility model is: have a plurality of wire casings that go out on the base plate of described sticking department.
The rectangular trapezium structure of the cross section of described snap close.
After adopting said structure, the utility model is installed on the skeleton circuit board, by cooperating of snap close and base plate, circuit board is fixedly secured on skeleton.Be welded in the lead-out wire on the circuit board, impose on the pressure of circuit board by the skeleton snap close, lead-out wire closely evenly is squeezed in out in the wire casing by circuit board, the stress point of lead-out wire is transferred on the insulating barrier that is pushed by circuit board, has protected solder joint not stress; Because the skeleton snap close fixedly secures circuit board, makes the enamelled wire solder joint that is welded on the circuit board firm, can not fracture, can not contact with stator core or end cap yet, guarantee that insulating properties is good.
The utility model structural design is ingenious, and need not add part just can be accurately fixing with circuit board, and easy for installation.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figures 1 to 4: the circuit board skeleton of a kind of button with lock of the present utility model, comprise body 1 and sticking department 2, body 1 comprises octagon outside framework 11 and support 12, and support 12 is distributed in the inside of octagon outside framework 11 and is connected with eight limits respectively; Sticking department 2 comprises the frame 21 and base plate 22 with integrative-structure, frame 21 forms to fall " door " font structure with base plate 22, base plate 22 is provided with six and goes out wire casing 23, the both sides frame 21 of sticking department 2 exceeds plane, base plate 22 place, exceed the snap close 211 that setting is extended to the inside on the part at frame 21, and leave between snap close 211 and the base plate 22 and the corresponding gap of circuit board 3 thickness, the wherein rectangular trapezium structure of the cross section of snap close 211.
The designed skeleton of the utility model is with circuit board 3 assembling process the time; the mating part oblique cutting of circuit board 3 is gone in the gap of leaving between skeleton sticking department snap close 211 and the base plate 22; by cooperating of snap close 211 and base plate 22; circuit board 3 is fixedly secured on skeleton; lead-out wire and enamelled wire on the circuit board 3 closely evenly is squeezed in going out in the wire casing 23 of sticking department simultaneously; the stress point of lead-out wire is transferred on the insulating barrier that is pushed by circuit board, protected solder joint not stress.
Of the present utility model simple in structure, easy for installation, described skeleton injection molded of thermoplastic insulation's property plastics.
