Fig. 3 is the front view of the utility model electric connector terminal;

Fig. 4 is the front view of socket connector as shown in Figure 1.

[embodiment]

See also Fig. 1 to shown in Figure 3, the socket connector 100 that the utility model electric connector terminal 30 is installed can be installed on the printed circuit board (PCB) (not shown), is used to accept central authorities

Reason device (CPU) core

(not shown) also

It electrically conducts with corresponding loop on the printed circuit board (PCB), and it comprises body 10 and some above-mentioned terminals 30.

See also shown in Figure 3ly, body 10 is to adopt the insulating material ejection formation, and it roughly is square tabular.This body 10 is provided with and runs through its upper and lower some accepting grooves 11 of surperficial 12,13, and accepting groove 11 is used to accommodate electric connector terminal 30.The direction of offering of definition accepting groove 11 is a vertical direction.

See also Fig. 2 and shown in Figure 4, electric connector terminal 30 include a location-plate 31, can be respectively and central authorities

Reason device core

And first contact site 32 and second contact site 33 of the circuit board electrical contact in corresponding loop.Location-plate 31 is used for

Terminal 30 is fixed in the accepting groove 11 of body 10.After terminal 30 was fixed in the accepting groove 11, first contact site 32 and second contact site 33 extended out with lower surface 13 from the upper surface 12 of body 10 respectively.

Seeing also Fig. 2 to Fig. 4 shows, first contact site 32 of terminal 30 comprises an elastic arm 321 and two rigid arm 322,323, wherein, the all relative vertical direction of so-called elastic arm 322 with rigid arm 323, be that better and in the horizontal direction rigidity is better for elastic arm 322 in the vertical direction elasticity, and opposite rigid arm 322,323 is better in the vertical direction rigidity, and elasticity is better in the horizontal direction.Elastic arm 321 ends are provided with an elastic contact part 3210, and this elastic contact part 3210 can pass through elastic arm 321 in the vertical direction elastic deflections, and this elastic contact part 3210 is arc surfaces.Central authorities

Reason device (CPU) core When contacting with elastic contact part 3210, friction is less between the two for arc surface makes because of elastic contact part 3210, just easy between the two slide relative.Rigid arm 322,323 ends are provided with

rigidity contact site

3220,3230, and

rigidity contact site

3220,3230 can not be in vertical direction deflection.In central authorities Reason device (CPU) core

Interfere on the vertical direction with

rigidity contact site

3220,3230, i.e. central authorities Reason device (CPU) core

Contact for rigidity with rigidity contact site 3220,3230.Elastic contact part 3210 at vertical direction a little more than

rigidity contact site

3220,3230, in central authorities Reason device (CPU) core

When contacting with 3 property of terminal, core

Contact with elastic contact part 3210 earlier, elastic contact part 3210 is followed core

Displacement straight down and elastic arm 321 is deflected down, elastic contact part 3210 can be because of elastic arm 321 downward biases then at core

Last generation slippage.At core

Ran into the rigidity contact site at 3220,3230 o'clock, core

Stopped to bottom offset by

rigidity contact site

3220,3230 low grades.Like this, core

With the same terminal 3 existing Elastic Contact points that contact by elastic contact part 3210, the rigidity contact point by 3220,3230 contacts of rigidity contact site is arranged again.Core

And the way of contact between the terminal 3 is various, and contact point is a plurality of.Keeping out of

rigidity contact site

3220,3230 prevents elastic arm 321 overtired distortion when being subjected to the external force extruding, and

rigidity contact site

3220,3230 and core

When having certain interval, the elasticity of elastic contact part 3210 makes connector and core again

Electrically conduct, can guarantee terminal and core

Between keep well electrically conducting.Elastic arm 321 can extend out from terminal 3 same ends with rigid arm 322,323 in the present embodiment, and certainly according to actual operating position, elastic arm 321 can extend out from the different ends of terminal with rigid arm 322,323.

The structure of second contact site 33 in the present embodiment is different with first contact site, and second contact site also can be arranged to the structure identical with first contact site among other embodiment certainly.
