Two-terminal 20, the first elastic component 50 for being sheathed on the first terminal and the second elastic component 60 for being sheathed on Second terminal.This embodiment party
In formula, first, second elastic component preferred compressed spring, first, second terminal structure is identical, and orthogonal sets interactively with each other are loaded on one
Rise.
The first terminal 10 includes the first docking section 11, extends from first docking section one end and be formed at the first of free terminal
Connecting portion 12, Second terminal includes the second docking section 21, extends from second connecting portion one end and be formed at the second of free terminal
Connecting portion 22.First connecting portion 12 includes a pair first cantilevers 121, is held on two relative surfaces of the second docking section 21；Second
Connecting portion 22 include a pair second cantilevers 221, be held on two relative surfaces of the first docking section, so as to realize the first terminal 10 with
The good electric connection of Second terminal 20.Referring to Fig. 5, the free terminal of first, second docking section is defined as first, second contact
Portion 13,23, connects with chip module 200 and circuit board 300 respectively, to realize the electric connection of chip module and circuit board.
Referring to Fig. 3, electric connector terminal 100 is installed on the insulating body 30 of electric connector, and insulating body includes first
The body 32 (the first noumenon and the second body only show one part) of body 31 and second, the first noumenon 31 is defined and chip dies
The interface 311 that group 200 is connected, the second body 32 is defined and connected with circuit board 300 and the mounting surface relative with interface
321.The assembling of first, second body 31,32 coordinates and is formed the accepting groove 33 for housing electric connector terminal, the accepting groove 33 to run through
Mounting surface and interface, conducting terminal are contained in terminal groove.
Fig. 4 is refer to, electric connector is attached to circuit board 300, the first noumenon 31 is in accepting groove 33 near interface 311
Opening at be provided with the first stop part 331, the second body 32 is provided with the second stop part in accepting groove at the opening of mounting surface
332, be limited to electric connector terminal in accepting groove 33 by the first stop part 331 and the second stop part 332, only allows first to contact
Portion 13 protrudes from the contact site 23 of interface 311 and second and protrudes from mounting surface 321.The end thereof contacts of first elastic component 50 first stop
Portion 331, the other end of the first elastic component 50 is then resisted against the free terminal of second connecting portion 22, and (i.e. Second terminal 20 is away from second pair
The free terminal of socket part 21), the first elastic component 50 just at free state or can be slightly compressed.Two cantilevers 221 are by first
Elastic component 50 is supported and can moved up and down along the first docking section 11 of the first terminal.Second elastic component 60 is then in free shape
State, due to Action of Gravity Field, one end contacts with the second stop part 332 for it, and the other end is then spaced apart with first connecting portion 12.Certainly
