313；The fixing terminal 32 has the fixed part 321 of fixed bottom plate 12, protrudes out bottom plate 12 and can be with the butting section of elastic arm 311
313 legs 323 for being located against portion 322 and extending insulating body for being separated from each other or contacting, to realize detecting function, i.e., right
Connect before thing 200 inserts, the butting section 313 of the flexible terminal 31 is connected to being located against in portion 322 of fixing terminal 32, realizes letter
Number conducting；When docking object inserts, docking object can extrude flexible terminal 31 and deform, and butting section 313 and fixing terminal 32
The portion 322 that is located against be separated from each other, both signals disconnect, with detecting have docking object insertion, docking extract docking chamber before, should
Butting section 313 contacts with each other with being located against portion 322, plays reminding effect, and can prevent loss of data.
For a pair of buckles 50 respectively on the two side 14 of insulating body 10, each buckle 50, which has, protrudes into docking chamber
Projection 51 in 101, the projection can guide docking object insertion docking intracavitary, and the projection 51 contacts with the groove 201 of docking object,
The stability that docking object is combined with electric connector is provided.
Refer to shown in Fig. 2 and Fig. 4, the conducting terminal 40 includes being fixed on holding parts 41 on insulating body 10, convex
The contact site and welding foot 42 stretched into host cavity, the bottom plate 12 have the recessed of the contact site 42 of multiple corresponding conducting terminals 40
Mouth 15, when docking object inserts, the contact site can be housed in recess, reduce the height of electric connector, also increase the bullet of terminal
Property deformation space, certainly, in the present embodiment, the contact site has the first contact site and the second contact site, is detailed later.
Refer to shown in Fig. 5 to Figure 10, in the present embodiment, an at least conducting terminal 40 has the first elastic arm 43 and the
Two elastic arms 44, first elastic arm 43 are connected with the one of the second elastic arm 44, and the 44 relative inverse folding 180 of first elastic arm 43 of the second elastic arm
Degree forms, and is horizontally mounted in a manner of as shown in Figure 7 exemplified by electric connector, and the second elastic arm 44 is located at the downside of the first elastic arm 43, i.e.,
First elastic arm 43 has the first contact site with respect to the second elastic arm 44 closer to the center of host cavity 101, the end of the first elastic arm 43
431, the second elastic arm 44 has the second contact site 441 protruded into host cavity 101, and the second contact site 441 relative first connects
Contact portion 431 is more protruded into 101 in host cavity, i.e., the face on the basis of bottom plate 12,441 relative first contact site 431 of the second contact site
Further from reference plane.I.e. when the host cavity of docking object insertion electric connector, the docking object first contacts with the second contact site 441,
And second elastic arm 44 deform upon down, the first elastic arm 43 is separated from each other with the second elastic arm 44, now, docking object and the first elastic arm
44 the first contact site 431 contacts.
