It please refers to Fig.1 and Fig. 2, the utility model embodiment provides a kind of conducting terminal 100, conducting terminal 100 includes being in
Plate-shaped bar body portion 10,10 upper end of main body being vertically arranged tilt 10 lower end of elastic portion 20 and main body for extending and obtaining
Extend obtained interconnecting piece 30, there is elastic portion 20 good elasticity, interconnecting piece 30 to be connected with weld part 40, weld part 40 and master
Body portion 10 is substantially in 90 degree of bendings, and conducting terminal 100 is soldered to printed circuit board by solder.
Wherein, the end of elastic portion 20 reversely bends extension and obtains invayination 21, and invayination 21 is close to elastic portion 20, into
One step, the end of elastic portion 20 is reversely bent to form downwards invayination 21, specifically, elastic portion 20 includes plate-like portion 22, bullet
Property arm 23 and contact site 24,10 upper end of main part connect with one end of plate-like portion 22, the other end of plate-like portion 22 and elastic arm 23
One end connection, the other end of elastic arm 23 connect with one end of contact site 24, invayination 21 be from the end of contact site 24 to
It is reversely bent to form down.Optionally, invayination 21 extends to 24 lower section of contact site and is close to contact site 24；Alternatively, invayination
21 extend to 23 lower section of elastic arm and are close to both contact site 24, elastic arm 23；Alternatively, invayination 21 extends to plate-like portion 22
Simultaneously it is close to contact site 24, elastic arm 23,22 three of plate-like portion lower section.Wherein, the contact site 24 of 20 end of elastic portion be used for and
Chip contacts, and is extended with invayination 21 since the contact site 24 of 20 end of elastic portion is reversely bent so that 20 end of elastic portion
The contact surface of contact site 24 and chip is shiny surface, prevents from scratching chip to realize, further, since the invayination 21 prolongs
It extends to the lower section of elastic portion 20 and is close to the lower surface of elastic portion 20, therefore, can preferably prevent conducting terminal 100 from scratching
Chip, while the thickness divided with chip contact site 24 in elastic portion 20 and intensity are also enhanced, it prevents in installation process by easily
It fractures.
In some embodiments, a side of main part 10 convexes to form fixed part 11, is also set up on main part 10 tangible
Become slot 12, deformation slot 12 is close to the side where fixed part 11, and deformation slot 12 is in closed structure, and the quantity of deformation slot 12 is extremely
It is one less.Deformation slot 12 has crush resistance, when the mounting hole for the insulating body that conducting terminal 100 is assembled into electric connector
When middle, compressional deformation slot 12 after 11 stress of fixed part so that the power that main part 10 is shared is less, therefore conducting terminal 100 is not easy
Deformation ensures the fraction defective reduction of conducting terminal 100 after assembling.
The lower end of 30 main body 10 of interconnecting piece is extended, and one side is connect with main part 10, and another side is certainly
By holding, there are separate slots 50 between interconnecting piece 30 and main part 10.
In one embodiment, the lower end of interconnecting piece 30 is connect with weld part 40, the upper end of interconnecting piece 30 and main part 10 it
Between formed separate slot 50, optionally, deformation slot 12 is set to the top of separate slot 50.
In one embodiment, form acute angle between interconnecting piece 30 and main part 10, in specific embodiment, interconnecting piece 30 from
By holding from the lower end of main part 10 outwardly away between having centainly between interconnecting piece 30 and main part 10 in the horizontal direction
Away from.As a preferred embodiment, the acute angle formed between interconnecting piece 30 and main part 10 is less than 30 ° so that conducting terminal 100
Bear uniform internal stress when external force.
In one embodiment, main part 10 is provided with extension 60 in the lower section of fixed part 11, and extension 60 is located at separate slot
50 side, during conducting terminal 100 is assembled into insulating body, extension 60 can balance the stress of main part 10,
So that the conducting terminal 100 after assembling is more secured, stable, fraction defective is reduced.
