Description of drawings
Fig. 1 is the utility model and circuit board and electric actuator assembly structure schematic diagram;
Fig. 2 is the utility model and circuit board assembly structure schematic diagram.
The specific embodiment
Below with reference to preferred embodiments and drawings, the utility model is described in further detail.
As depicted in figs. 1 and 2, case 3 usefulness elasticity ABS plastic integral molded plastic preferably form, be provided with the elastic fastening hook 31 of four ligules above, Dui Ying 4 locating holes 21 that are provided in a side of electromagnet framework 22 with it, being set as elastic fastening hook 31 heads cylindrical is because the processing circular hole is easier than the pore volume of other shapes on electromagnet framework 22.It can also be seen that the incline bench 32 that the inner face of elastic fastening hook 31 is convexly equipped with and be located at the boss 33 of elastic fastening hook 31 both sides and the face of cylinder 37 structures of the projection of elastic fastening hook 31 bottoms from Fig. 2.
The case 3 of at first circuit board 1 being packed into during installation, work as board edge in the loading procedure and touch incline bench 32, four elastic fastening hooks 31 outwards strut simultaneously under external force, circuit board 3 had passed through incline bench 32 after the soffit of circuit board 3 touched boss 33 end faces, four elastic fastening hooks 31 resile, the upper surface of circuit board is just in time pushed down in the bottom surface of incline bench 32, and one of circuit board is fixed.Owing to the product variety reason, the not necessarily complete situation about conforming to of appearance and size that can have circuit board with the case inner cavity size, for the versatility that improves case is considered width to be equated but the short circuit board of length also can be packed into, so just need the spacing of horizontal direction, the face of cylinder 37 of projection is set in elastic fastening hook 31 bottoms, simultaneously half slot 13 is set, can addresses this problem easily at the circuit board correspondence position.
