Subheader portion contact area is due to using 180 degree bending clad type structure design so that contact area thickness is changed into 0.60mm, increase
The sectional area of terminal conductor electric current transmission.
Further, the terminal is fixed on the bottom of pump shell by integral type Shooting Technique, and terminal tails penetrate
It is connected in pump shell with PCB control panels, and terminal head portion then stays in outside.Using insert molding（Press from both sides thing molding）
Integral type Shooting Technique, add the bond strength of terminal and plastic cement pump shell.
The terminal tails of the terminal form edge rolling structure, and the rear body section of pawl spring is also edge rolling structure, pawl spring
If front portion be dry plate in fork structure pawl spring shell fragment, pawl spring shell fragment extends towards top rake and shunk towards pawl spring central axis direction
The open pore that a bore is less than pawl spring Rear body entrance is formed, is passed after terminal tails insertion pawl spring by the open pore, pawl spring
Shell fragment is clamped in the surface of terminal tails.Terminal tails are used and taken all of（Edge rolling）Structure design, allows terminal tails and pawl spring shell fragment
Contact area is bigger, connection is more firm, more reliable, safer.And pawl spring is arranged in pairs or groups using structure is taken all of with sleeve pipe, can be formed more
Closely electrical connection.
The utility model directly clamps water pump by setting pawl spring at the fixing hole of PCB control panels with pawl spring shell fragment
The terminal tails of connector, so that forming closely electrical connection between the terminal of water pump coupling and PCB control panels；It is whole
Individual structure has the advantages that safe, easy to assembly, water resistance is good, has very high practical value, through wide popularization and application
Good economic benefit and social benefit can be produced.
