Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of motor switch shell, referring to Fig. 1, including being fixedly installed in the inner wall of shell 1 and for abutting pcb board (figure
In be not shown) abutting part 2 of lower surface, the inner wall that is fixedly installed in shell 1 be used to abut multiple elastic cards of pcb board upper surface
Plate 3 and the positioning region 4 that grafting pcb board is used in shell 1, wherein elastic snap-gauge 3 is whole L-shaped.
Abutting part 2 and elastic snap-gauge 3 are connected to the lower surface and upper surface of pcb board respectively, limitation pcb board vertical direction
Displacement, the positioning region 4 for being plugged in pcb board limits the displacement of pcb board horizontal direction, and then achievees the purpose that fixed pcb board, thus
Improve the fastness that pcb board is installed in shell 1.
Specifically, abutting part 2 includes being installed on the abutting stupefied 22 of 1 inside of shell and being installed on 1 the multiple of outside of shell to support
Block 21 is connect, stupefied 22 sides for being distributed in pcb board are abutted, multiple abutting blocks 21 are distributed in pcb board along the length direction for abutting stupefied 22
The other side.The locational space for abutting stupefied 22 occupancy shell 1 is small, and multiple abutting blocks 21 and the contact area of pcb board are big, the two phase
Integrated structure is simple and compact, improves the stability that pcb board is installed in shell 1.
Specifically, two elastic snap-gauges 3 are symmetrical there are two the elastic settings of snap-gauge 3.Make the stress of pcb board in this way
More evenly, and then the stability of pcb board is higher, is not easy to loosen.
In conjunction with Fig. 2, specifically, elastic snap-gauge 3 includes supporting section 31, and be shaped in 31 end of supporting section and with
The connecting section 32 that pcb board upper surface abuts, the supporting section of the connecting section 32 of one of elasticity snap-gauge 3 close to the elasticity snap-gauge 3
31 side is equipped with recess 33.In actual installation pcb board, side is first connected under an elastic snap-gauge 3 by pcb board, then
By making another elastic snap-gauge 3 that elastic deformation occur, pcb board is filled under the elasticity snap-gauge 3 again later, and then complete peace
Dress, the setting of recess 33 are conducive to the flexibility for improving one of elastic snap-gauge 3, so that the elasticity snap-gauge 3 is easier to occur
Elastic deformation, and then be easier to be clamped pcb board.In addition, 32 end of connecting section for being provided with the elastic snap-gauge 3 of recess 33 is equipped with
Fillet slides into 32 lower section of connecting section for being connected in pcb board conducive to pcb board.
Specifically, the connecting section 32 of elastic snap-gauge 3 is equipped with the inclined-plane for importing pcb board, so that in clamping pcb board
When, the transition of pcb board and the connecting section 32 of elastic snap-gauge 3 is smoother, not easy damaged pcb board.
Referring to Fig. 1, specifically, positioning region 4 includes multiple positioning columns 41 for grafting pcb board, pcb board is equipped with and is used for
Multiple location holes of positioning column 41 are installed with, multiple positioning columns 41 are plugged in the positioning hole of pcb board, limit pcb board horizontal direction
Displacement so that the fixing-stable of pcb board horizontal direction.
Specifically, positioning column 41 is additionally provided with the abutting seat 42 for abutting pcb board lower surface, abuts seat 42 and further increase
The area of pcb board and the first abutting part 2 is not easy to loosen or bend so that pcb board is installed on stronger in shell 1.
In conjunction with Fig. 3, specifically, shell 1, by injection molding, shell 1 is set there are two die hole 5 is moved back, and two are moved back the difference of die hole 5
Positioned at the underface of two 3 connecting sections 32 of elastic snap-gauge, the setting of die hole 5 is moved back, convenient for worker after injection molding shell 1, to
It moves back in die hole 5 insertion to move back mould column 6 and the one end for moving back mould column 6 is connected to connecting section 32, and then by shell 1 by mold ejection,
It is convenient and practical.
