It connects more firm.As a further improvement, it is described widen preferably also formed in portion one with datum clamp face is at an acute angle beats
Glue surface.It then also may be selected to beat in glue at this time good solid between shell and objective plane to realize on gluing face and objective plane
It is fixed.
Harness can be drawn on circuit board, conventional structure is that harness welds on circuit boards.But since circuit board is smaller, line
The number of conductors of beam is relatively more and position is concentrated, therefore the spacing between conducting wire is very narrow, this results in welding difficulty larger and holds
Easily short circuit.A kind of preferable way is：Circuit board and harness are to be attached conducting by terminal base and terminal head.Separately
Outside, the harness is not connected preferably with shell, just without the transmission of power between such harness and shell, to circuit board and outside
Also the transmission of power is not present between shell, can avoid " fixing not to be good shell to transmit power by harness by lead to electricity in this way
The working face of road plate is close to objective plane bad " this problem.One of which solution is that shell is also formed with 1 foot
Enough big wire outlet positions.
