22 correspond the multiple through slots 33 being inserted through in the lid 3, and the supporting surface 321 abuts to downwards the upper surface
11, the confined planes 311 are arranged higher than the upper surface 11, and the extension 23 is located at the main part 31 and the ontology 1
Between, the stopping surface 231 is between the confined planes 311 and the upper surface 11, and the stopping surface 231 and the limit
It is equipped with a gap between plane 311, is defined as third space D3, with this by being electrically connected in electric connector first embodiment of the present invention
It connects device 100 to be completed, in the present embodiment, the third space D3 is smaller, so that the stopping surface 231 and corresponding institute
Confined planes 311 are stated relatively close to before the chip module 200 does not abut the elastic arm 22, the terminal 2 is in vertical direction
On displacement it is small, have preferable limit function.
As seen in figs. 7 and 11, after the lid 3 is placed on 1 top of ontology, the first support portion 32A is downward
The position of the terminal area 11A approximate centre is abutted to, eight the second support portion 32B abut to described outer separately down
Enclose region 11B.It is arranged between the second support portion 32B as described in the first support portion 32A and two of them in three-legged structure,
The first support portion 32A and the second support portion 32B described in two of them is respectively at the through slot region 31A and the perimeter region
Domain 31B forms the stronger triangular support bracket of a stability to the main part 31, and it is described to guarantee that the lid 3 can be steadily set to
1 top of ontology.
As shown in Figure 10 and Figure 11, after the lid 3 is placed on the top of the ontology 1,311 meeting of confined planes
Downward block is carried out to the stopping surface 231 of the terminal 2, guarantees that the bearing surface 211 is supported with the first part 141
Connect, the abutting part 254 is abutted with the second part 142 so that the terminal 2 and the ontology 1 realize it is stable
It is electrically conducted, while guaranteeing that the support arm 24 abuts to the upper surface 11, further ensure the terminal 2 and led with described
The stability being electrically conducted between socket part 14.
As shown in figs, before the electric connector 100 is installed on the circuit board 300, by multiple solders
4 correspond the position being placed in where multiple through-holes 13, then the electric connector 100 is mounted on the circuit board
On 300, then make 4 melted by heating of solder, wherein the solder 4 after melted by heating can be by the pin 25 and the electricity
Road plate 300 welds, to realize the welding between the terminal 2 and the circuit board 300, while the wherein portion of melted by heating
Divide the solder 4 that can flow to from the abutting part 254 from the guidance part 252 along the portion 251 that complies with, so that the pin
25 weld at the abutting part 254 with the second part 142, mutually support in the pin 25 and the second part 142
It connects in the case where being electrically conducted with realization, further reinforces the connection between the pin 25 and the second part 142.
As shown in Figure 8 and Figure 9, finally the chip module 200 is installed to 3 top of lid again, it is described at this time to connect
Mutually abutted between contact portion 221 and the chip module 200, with realize the terminal 2 respectively with the circuit board 300, described
Being electrically conducted between chip module 200.Wherein due to being equipped with the lid 3 above the ontology 1, so working as the chip dies
When block 200 presses down on the elastic arm 22, the chip module 200 is pressed down on to after certain distance, the chip module
The final position that 200 bottom can be abutted with the upper surface 11 of the lid 3 namely the chip module 200 is pressed into, this
Shi Suoshu lid 3 can support the chip module 200 to stop the chip module 200 excessively to move down, and then avoid described
Elastic arm 22 is excessively pressed down on by the chip module 200 and irreversible deformation occurs, and then guarantees the terminal 2 and institute
State stable between chip module 200 be electrically conducted.
As shown in figure 12, the electric connector 100 of electric connector second embodiment of the present invention and electric connector first of the present invention
The difference of embodiment is: the supporting surface 321 and the confined planes 311 in the vertical direction at a distance from be equal to the support arm
24 bottom surface and the stopping surface 231 in the vertical direction at a distance from so that being set to above the ontology 1 by the lid 3
Afterwards, when the bottom surface of the support arm 24 abuts to downwards the upper surface 11, the confined planes 311 abut downwards the stopping surface
231, therefore, in abutting against respectively with the lid 3 and the ontology 1 on vertical direction, i.e., the described terminal 2 exists the terminal 2
Block on vertical direction by the lid 3 and the ontology 1 directly defines the position of the terminal 2 in the vertical direction
It sets, so that the terminal 2 can not ensure that each pin 25 in the through-hole 13 towards moving at the upper side of the ontology 1
The abutting part 254 can with the corresponding second part 142 in position appropriate be abutted with realize be electrically conducted,
So that being electrically conducted between each terminal 2 and the junction 14 is stablized, effectively, while it ensure that each contact portion
221 can be in position appropriate to be electrically conducted with the chip module 200.
As shown in figure 13, the electric connector 100 of electric connector 3rd embodiment of the present invention and electric connector first of the present invention
The difference of embodiment is: the lid 3 does not include the multiple support portions extended vertically downward from the main part 31,
But the ontology 1 includes that the multiple support portions 32 to be formed are protruded upward from the upper surface 11, the main part 31 is in correspondence
The surface of each support portion 32 is equipped with a supporting surface 31, the supporting surface 31 and the confined planes 311 1
Sample is provided at the bottom surface of the main part 31, and the supporting surface 31 and the confined planes 311 are located at same level.
In conclusion electric connector of the invention has the advantages that
1) by the way that the lid 3 is arranged above the ontology 1, the chip module is supported upwards using the lid 3
200, to reduce the down force that the chip module 200 imposes the elastic arm 22, and then it effectively prevent the elasticity
Irreversible deformation or fracture occur because being excessively pressed for arm 22, guarantee between the terminal 2 and the chip module 200
It is electrically conducted.It is moved up simultaneously by stopping surface 231 described in 311 block of confined planes, i.e., the described confined planes 311 are to lower block
The only stopping surface 231, can effectively prevent the terminal 2 relative to the ontology 1 towards 200 side of chip module it is excessive on
Move, guarantee between the terminal 2 and the junction 14 being electrically conducted stablize and in place.
