Abstract
An electric connector comprises an insulating body, and a conductive terminal which consists of first conductive terminals and second conductive terminals. The insulating body is provided with a plurality of terminal holding holes, wherein, each holding hole is provided with the first conductive terminals and the second conductive terminals electrically connected with the first conductive terminals. An inclined part is arranged at one side of the holding holes of the terminals, and the second conductive terminals are provided with an elastic contact part. When a butt electronic component contacts with the first conductive terminals, the first conductive terminals move between the inclined part and the elastic contact part; when the butt electronic component is removed, the elastic contact parts of the second conductive terminals restore and rebound the first conductive terminals to the initial position. Because the electric connector is provided with the first conductive terminals, the first terminals move between the inclined part and the elastic contact part and compress the second conductive terminals, the first conductive terminals and the second conductive terminals are contacted in the compressible way.

[background technology]
Occurred a kind of chip module of LGA type now on some electronic product (as computer), the guiding access of this chip module is a washer-shaped, and the electric connector that is attached thereto is provided with the terminal that contacts with the conducting end compression.The electric connector of prior art, comprise insulating body and conducting terminal, insulating body is provided with the terminal containing slot of accommodating conducting terminal, conducting terminal is by the moulding of metal material integrated punching, comprise and be immobilizated in intrinsic holding parts, holding parts extends downwards and is provided with the weld part that welds mutually with circuit board, and holding parts extends obliquely and is provided with the contact site that compresses contact with chip module mutually.This electric connector is when installing chip module, and conducting terminal is easy to generate elastic fatigue after repeatedly bending, because contact site tilts and longer and unfavorable what dense arrangement.Owing to above reason, recently a kind of utilize two terminals to join electric connector that incompatible generation electrically connects has appearred again in industry, as No. 5362241, United States Patent (USP) US, it engages with a terminal that can elasticity flexibly connects by a fixing terminal, realizes that chip contacts with the elastic compression of circuit board.Though this electric connector is not easy to produce elastic fatigue, but also dense arrangement.But because the conducting terminal of this electric connector is not made up of a conducting terminal, but is made up of two conducting terminals, in the process that connects, only come transmission signals by a contact, it has increased resistance value, causes overall conductance not high.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
[utility model content]
The purpose of this utility model is to provide a kind of novel electric connector, can realize the better electric connection of electronic component and circuit board.
For achieving the above object, the utility model electric connector, be used to accept the butt joint electronic component, comprise insulating body and conducting terminal, conducting terminal comprises first conducting terminal and second conducting terminal, described insulating body is provided with the plurality of terminals accommodation hole, wherein each accommodation hole is provided with first conducting terminal and reaches second conducting terminal that connects mutually with first conducting terminal, described terminal accommodation hole one side is provided with rake, second conducting terminal is provided with elastic contact part, when butt joint electronic component compression contact first conducting terminal, first conducting terminal moves between rake and elastic contact part, when butt joint electronic component when removing, the elastic contact part reinstatement of second conducting terminal, and with first conducting terminal initial position that rebounds.
Compared with prior art, because electric connector is provided with first conducting terminal, first conducting terminal moves between rake and elastic contact part, its compressible second conducting terminal, make first conducting terminal compress contact mutually with second conducting terminal, its contact impedance is lower, can realize the better electric connection of electronic component and circuit board, and can carry out dense arrangement.

[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.
As depicted in figs. 1 and 2, the utility model electric connector 1, can electrically connect mutually with circuit board 2, be used to accept wafer module 3 (certainly, also can be circuit board, perhaps other electronic components), comprise insulating body 10 and conducting terminal, conducting terminal comprises first conducting terminal 4 and second conducting terminal 5, insulating body 10 is provided with plurality of terminals accommodation hole 100, wherein each accommodation hole 100 is provided with first conducting terminal 4 (in the present embodiment, described first conducting terminal is a Metal Ball) and second conducting terminal 5, described wafer module 3 is provided with spherical contact site 30 (with reference to shown in Figure 5), and when wafer module 3 moved down, this sphere contact site 30 contacted with Metal Ball 4, make 5 distortion of second conducting terminal behind Metal Ball 4 pressurizeds, form the electric connection of circuit board 2 and wafer module 3, when wafer module 3 was removed, 5 reinstatements of second conducting terminal were with Metal Ball 4 initial position that rebounds.Wherein, described Metal Ball 4 is free to rotate when mobile, rolls as the surface at second conducting terminal, can scrape off the oxide-film on second conducting terminal 5 like this, reaches better electrically contact.
With reference to shown in Figure 2, described terminal accommodation hole 100 1 sides are provided with the rake 101 that can supply Metal Ball 4 to move, Metal Ball 4 can be moved down along described rake 101, in addition, described rake 101 upper ends are provided with the overhead kick 102 that prevents that Metal Ball 4 from ejecting, can protect when second conducting terminal 5 rebounds Metal Ball 4, not make Metal Ball 4 eject these terminal accommodation holes 100; Described terminal accommodation hole 100 opposite sides be provided with for the distortion of second conducting terminal 5 allow bit space 103, when 5 distortion of second conducting terminal, can make second conducting terminal 5 towards allowing bit space 103 distortion.Convex with posting 104 (as Fig. 4) around the described insulating body 10, can locate described chip module 3, described insulating body 10 opposite sides convex with reference column 105, can match with the location hole (not shown) of setting on the circuit board 2, to locate this electric connector 1 to circuit board 2, these reference column 105 different sizes can play the effect of fool proof.
Described second conducting terminal 5 can relatively move with Metal Ball 4, as shown in Figure 3, wherein said second conducting terminal 5 comprises that holding parts 50 reaches by holding parts 50 upwardly extending contact sites 51, by the holding parts 50 downward weld parts 52 that extend, described weld part 52 can weld mutually with circuit board 2, realizes the electric connection of itself and circuit board 2.Described contact site 51 is provided with the groove 510 that moves for Metal Ball 4, described Metal Ball 4 can be clamped between contact site 51 and the rake 101, when chip module 3 stressed when moving down, Metal Ball 4 moves or rolls along described groove 510, contacts with second conducting terminal 5, and the contact site 51 of second conducting terminal 5 is deformed, form and electrically connect, when not stressing, described contact site 51 upwards promotes Metal Ball 4 because of reaction force, gets back to initial condition.
