In a second example of the conventional electric connector, the SMT terminal 21 of the housing 207 is provided.
Since the SMT terminal 210 is pre-tensioned to ensure the contact between the SMT terminal 210 and the pad 211 of the card 208, when the card is slid from the horizontal direction and inserted into the housing, the SMT terminal 210 is soldered on the pad 211. There was a problem that the paste was separated and the soldering was poor. Further, in the first example, the housing and the card must be overlapped from the vertical direction and screwed or riveted, and there is a problem that mounting is difficult.

[0010] In FIG.
When a pressing force is applied in the direction of the arrow in order to press the card onto the card arm 01, the lock arm 107 made of an elastic material
, And the convex portion 108 having a semi-elliptical cross-sectional shape engages with the engagement groove 104 to be in the fixed state shown in FIG. In this state, the SMT terminals 105 are in contact with the pads (not shown) of the card 101, and the solder 1
At 06, an electrical connection is made. Card 1 according to this example
Since the SMT terminal is not slid in the horizontal direction and is fixed by pressing in the vertical direction between the SMT terminal and the housing 102, the SMT terminal does not separate the solder paste of the pad, so that good soldering is performed.
