Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, especially a kind of electric connector that is used to be electrically conducted LGA (land grid array, planar lattice array) cake core module and circuit board.

[background technology]

As shown in Figure 1 and Figure 2, at present comprise insulating body 4 and be located in plurality of terminals 5 in the insulating body 4 in order to the electric connector 3 that connects LGA cake core module 1 and circuit board 2.During assembling, earlier electric connector 3 is installed on the circuit board, by welding or compression contact electric connector 3 and circuit board 2 are electrically conducted, again chip module 1 is pressed to terminal 5 upper ends, chip module 1 and electric connector 3 are electrically conducted, so just reached the purpose that chip module 1 and circuit board 2 are electrically conducted indirectly.The design of this electric connector terminal need be considered several factors, to guarantee firmly to be fixed in the insulating body such as terminal, and the terminal upper end must have bigger elasticity, terminal is not easy to damage or the like when chip module repeatedly presses down, therefore the design of terminal is very complicated, if but terminal structure is very complicated, then can cause the raising of cost unavoidably.

Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, and it can be simplified terminal design and have lower cost.

For achieving the above object, the utility model electric connector, be used for connecting first electronic building brick and second electronic building brick, correspondingly on this first electronic building brick and second electronic building brick be provided with some pads, it comprises insulating body and is located in plurality of terminals in the insulating body, this electric connector further comprises cover plate, and this terminal is exposed to this cover plate surface.

Compared with prior art, the utility model electric connector is because there is the setting of cover plate, so can simplify terminal design and have lower cost.

[embodiment]

Below in conjunction with accompanying drawing the utility model electric connector is made and to further describe.

Please refer to Fig. 3, Fig. 4 and Fig. 5, the utility model electric connector comprises insulating body 10, is arranged in cover plate 20 and some terminals 30 that is located in insulating body 10 of insulating body 10 tops.

It is one tabular that this insulating body 10 roughly is, its both sides extend upward and are provided with sidewall 12, with positioning chip module (not drawing among the figure), extend downwards and be provided with some reference columns 14, when assembling mutually, to play the effect of location with circuit board 40, these reference column 14 ends also are provided with buckle 16, with the electric connector snap fit on circuit board 40.Certainly, this electric connector can not established buckle at the reference column end yet, but sets firmly a metal buckle in addition, and electric connector is fixed on the circuit board.This electric connector top also is provided with a metallic elastic hook 18 fixed structure of other shape (certainly also can be), with fixedly cover plate 20 and chip module.

This cover plate 20 is made for insulating material, and corresponding terminal is provided with plurality of holes 22.

This terminal 30 is formed by the metal sheet punching out, it roughly is " U " shape, the fixed arm 32 that comprises almost parallel and elastic arm 34 and the connecting portion 36 that is connected and fixed arm 32 and elastic arm 34, these elastic arm 34 free terminals are provided with the alar part 342 that is positioned at both sides and are positioned at the contact site 344 of central authorities.

During assembling, earlier terminal 30 is inserted in the insulating body 10, make hole 22 corresponding terminals 30 then and cover plate 20 is placed on insulating body 10 tops, at this moment, terminal alar part 342 can prop up cover plate 20, make between cover plate 20 lower surfaces and insulating body 10 upper surfaces and leave certain interval, and cover plate 20 upper surfaces can extend in termination contact portion 344.When chip module was installed, cover plate 20 can move down with termination contact portion 344.This electric connector terminal elastic arm is long, thereby has elasticity preferably, and this terminal is subjected to the protection of cover plate, causes excessive shock when chip module presses down Shi Buhui, thereby can protect terminal to avoid infringement.Therefore, this its has the electric connector of cover plate can avoid because of will realizing that above-mentioned functions becomes complicated structure with terminal design, thereby can significantly simplify the design of terminal, but also has lower cost.

Fig. 6, Figure 7 shows that another embodiment of the utility model electric connector, in the present embodiment, this electric connector also comprises insulating body 50, is arranged in cover plate 60 and some terminals 70 that is located in insulating body 50 of insulating body 50 tops.This cover plate 60 is also made for insulating material, and corresponding terminal 70 is provided with plurality of holes 62.This terminal 70 roughly is "＜" shape, comprises main body 72 and is positioned at the last contact site 74 and following contact site 76 at main body 72 two ends, and this two contact site is all less than main body.This insulating body 50 is provided with the plurality of terminals accepting groove, and each terminal containing slot is equipped with second resettlement section 54 that is used for accommodating first resettlement section 52 of terminal bodies 72 and is used for accommodating contact site 76 under the terminal, this second resettlement section 54 is less than terminal bodies 72, can not come off downwards so that terminal can be positioned in the terminal containing slot.These cover plate 60 holes 62 are also less than terminal bodies 72, thereby this cover plate can avoid terminal to come off from terminal containing slot after installing.Like this, this terminal must not be provided with the fixed part that fixes with insulating body, and can well terminal be fixed in the terminal containing slot, so terminal structure is much simple relatively, so can significantly simplify the design of terminal and have lower cost.

Certainly, be two kinds of embodiments of the utility model electric connector more than, persons skilled in the art can design the cover plate of other shape and structure by foregoing description, simplify the design of terminal and make electric connector have lower cost.

The utility model electric connector also can be used for other and two has on the electronic building brick of pad except can be used between LGA cake core module and the circuit board, as between circuit board and the circuit board or the like.
