Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of in order to connect the electric connector of planar grid array chip module especially.
[background technology]
Along with the integrated application of systems technologies such as multimedia, communication and computer, no matter be desktop computer or mobile computer at present, its function from strength to strength, the circuit design of main frame is also more complicated.
At present, industry generally adopts electric connector to remove to electrically connect chip module to circuit board.It comprises insulating body and is located in plurality of terminals in the body and tin ball and the metal upper casing and the metal lower shell that can flexibly connect mutually, and be used for rocking bar that metal upper casing and metal lower shell are fixed together, wherein insulating body is between metal upper casing and metal lower shell.Can be by the tin ball bonding being connected to the mode of pad on the circuit board, insulating body is fixed on the circuit board, insulating body pressed metal lower casing also is fixed on the circuit board metal lower shell simultaneously, by rocking bar pressed metal upper casing, chip module is fixed in the electric connector again.Like this, just realized being connected of chip module and circuit board.But circuit board is provided with scaling powder during owing to welding, and during by heat fused tin ball, scaling powder also evaporation rising simultaneously condenses on the terminal sometimes, causes loose contact between terminal and the chip module, influences its normal electric connection.
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 its contact is good, can realize normal the electric connection.
In order to reach above-mentioned creation purpose, the utility model electric connector can be installed on the circuit board, comprises body and is located in plurality of terminals and scolder in the body, be provided with an opening that runs through the body upper and lower surface in the middle of the body, the body lower surface is provided with the fin of sealing in around openings.
Compared with prior art, the utility model electric connector is agglomerated to the phenomenon on the terminal in the time of eliminating or reduce the scaling powder evaporation, can guarantee excellent contact between terminal and the chip module, realizes its normal electric connection.

Fig. 2 is the three-dimensional combination figure of another angle shown in Figure 1;
Fig. 3 is the three-dimensional exploded view of the utility model electric connector;
Fig. 4 is the three-dimensional exploded view of another angle shown in Figure 3;
The vertical view of Fig. 5 the utility model electric connector;
Fig. 6 is the partial enlarged drawing of the utility model electric connector.
[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.
Extremely shown in Figure 6 as Fig. 1, the utility model electric connector 1, can be installed on the circuit board (not icon), be used to accept LGA chip 2 (certainly, also can be other chip module or other electron component), it comprises insulating body 10 and is located in plurality of conductive terminals (not shown) and the scolder (being tin ball 3 in the present embodiment) in the insulating body 10, the metal upper casing 12 and the metal lower shell 13 that can flexibly connect mutually, and is used for rocking bar 14 that metal upper casing 12 and metal lower shell 13 are fixed together.Wherein insulating body 10 is contained between metal upper casing 12 and the metal lower shell 13, and terminal protrudes out insulating body 10 upper surfaces.Rocking bar 14 is by an axle center part 140, and the operating portion 141 that is approximately perpendicular to axle center part 140 reaches from axle center part to be formed to projecting inward pressing part 142.But rocking bar 14 pressed metal upper casings 12 are firmly to be fixed on LGA chip 2 in the electric connector 1.
Insulating body 10 is made up of the insulating material that slightly is square, and LGA chip 2 is placed in wherein.Insulating body 10 is provided with some terminal containing slots (not shown) of accommodating conducting terminal, and the gulde edge piece 100 above terminal containing slot is arranged around it.Conducting terminal is arranged in this terminal containing slot, at least one end is higher than the accepting groove of insulating body 10 and is bending formation contact jaw, its peak is lower than gulde edge piece 100 upper surfaces, and its lower end can be connected with tin ball 3, welds together by the upper surface of tin ball 3 with circuit board.In addition, in the middle of insulating body 10, be provided with an opening 101 that runs through insulating body 10 upper and lower surfaces, wherein lower surface is provided with the fin 102 of sealing around opening 101, fin 102 is to be extended to form downwards by body 10 lower surfaces, this fin 102 is between opening 101 and tin ball 3, but butt is to circuit board, and what protrude out in addition in the both sides of the edge of insulating body 10 lower surfaces that height equates with the height of fin 102 is some protruding 103, but butt is to circuit board.
The circuit board pad is provided with scaling powder (not shown), when being soldered to insulating body 10 on the circuit board by the tin ball, in the process of heating, tin ball 3 and scaling powder are melted simultaneously, when 3 coolings of tin ball, just realized firmly being fixed to insulating body 10 on the circuit board, insulating body 10 pressed metal lower casings 13 make metal lower shell 13 also be fixed on the circuit board simultaneously, again by rocking bar pressed metal upper casing 12, LGA chip 2 is fixed in the electric connector 1, like this, just realized the electric connection of LGA chip 2 with circuit board.
The utility model electric connector is owing to the fin that is provided with sealing at the insulating body lower surface, in welding process, even the evaporation of the scaling powder on the circuit board can not condense on the terminal yet.Therefore, excellent contact between terminal and the LGA chip can be guaranteed, its normal electric connection can be realized.
Certainly, in the foregoing description, fin also not butt to circuit board, make between fin and the circuit board certain clearance is arranged, can reduce the scaling powder evaporation and the time being agglomerated on the terminal, or fin is not to be extended to form downwards by the body lower surface yet, but a fin of setting up in addition.Also can reach same effect.
