Portion 216 is inserted in circuit board 300, and second junction 224 contacts with the surface of circuit board 300, so as to reduce surface
The quantity of solder type terminal, help to improve the flatness of the second weld part 222 of Second terminal 22.First face 2140
There is gap, second face above the circuit board 300 and between first face 2140 and the circuit board 300
2240 contact with the surface of circuit board 300, i.e., described first face 2140, second face 2240 is away from the circuit board 300
Surface so that when second face 2240 contacts with the surface of circuit board 300, first face 2140 and the circuit board
There is gap between 300, so that during terminal 2 is welded in the circuit board 300, the first weld part of insert type
212 will not impact to the flatness of the second weld part 222 of surface soldered type, avoid because the first weld part 212 supports
Connect the circuit board 300 so that there is gap between the second weld part 222 and circuit board 300, cause the missing solder of Second terminal 22
Phenomenon.
Fig. 5 and Fig. 6 are referred to, there is one first angle theta 1, institute between first face 2140 and the circuit board 300
State the first angle theta 1 to set for acute angle, in the first embodiment of the invention, first angle theta 1 is 5 °, is connected described first
When portion 216 inserts the circuit board 300, first extension 214 is resiliently flexible, so as to disperse the external world for described
The active force of the first terminal 21, preferably protect the first terminal 21.Simultaneously because solder（It is not shown）In the first end
When son 21 welds the circuit board 300, it can be climbed upwards along the first terminal 21, first face 2140 is obliquely installed,
It effectively can prevent from climbing the phenomenon of tin.There is one second angle theta 2 between second face 2240 and the circuit board 300,
Second angle theta 2 is that acute angle is set, and in the first embodiment of the invention, second angle theta 2 is 5 ° so that described the
During two-terminal 22 installs the circuit board 300, the first edge 2241 touches the circuit board 300 at first, from
And make it that the flatness of second weld part 222 more preferably controls, reduce difficulty of processing.Second face 2240 and the circuit
