Abstract

The utility model discloses a conductive terminal for electrically connecting a chip module and a circuit board, which comprises: a main body, an elastic portion bent upward from the main body, a connecting portion extending downward from the main body, and the connecting portion A weld that is connected and has a certain included angle. The connecting portion includes a pair of connecting arms arranged in parallel to reduce resistance and inductance of the conductive terminals.

Description

Conducting terminal

[technical field]

The utility model relates to a kind of conducting terminal, especially a kind of conducting terminal that electrically connects chip module and circuit board.

[technical background]

China's utility model patent has disclosed a kind of conducting terminal that electrically connects chip module and circuit board No. 2833926, consult its accompanying drawing Fig. 3 to Fig. 5, this conducting terminal comprises base portion 1, extends the holding parts 4 that is provided with from the weld part 2 of base portion 1 extension downwards, from base portion 1 upwardly extending elastic portion 3 and from base portion 1 one sides.The bottom width of this conducting terminal base portion 1 is bigger, and this bottom is connected with weld part 2, therefore, makes that the resistance of conducting terminal is bigger, and causes its elasticity not good.

A kind of means that address the above problem are that the bottom with the conducting terminal base portion is provided with carefullyyer, and still, this means make conducting terminal fracture herein easily.

Given this, be necessary to provide a kind of improved conducting terminal in fact, to overcome the defective of above-mentioned conducting terminal.

[utility model content]

The technical problem that the utility model solved provides a kind of conducting terminal, and this conducting terminal can reduce the resistance of terminal and the bonding strength of inductance and assurance main part and weld part junction.

In order to solve the problems of the technologies described above, the utility model provides a kind of conducting terminal, and it comprises: main part, autonomous body are bent upwards the connecting portion of the elastic portion of extension, the extension downwards of autonomous body and are connected and have the weld part of certain angle with connecting portion.Described connecting portion comprises a pair of linking arm that is arranged in parallel.

Compare with correlation technique, be connected by two linking arms that are arranged in parallel between the main part of the utility model conducting terminal and the weld part, this structure can reduce the resistance and the inductance of conducting terminal, also can increase the bonding strength of main part and weld part simultaneously by two linking arms.

Fig. 1 is the stereogram of the utility model conducting terminal.

Fig. 2 is the front view of the utility model conducting terminal.

Fig. 3 is the vertical view of the utility model conducting terminal.

[embodiment]

See also Fig. 1 to shown in Figure 3, the utility model is a kind of conducting terminal 10, can be used for being assembled in the electric connector (not shown), realizes the electric connection between circuit board (not shown) and the chip module (not shown).This conducting terminal 10 comprises connecting portion 13 that main part 11, autonomous body 11 upwardly extending elastic portion 12, autonomous body 11 extend and the weld part 14 that is connected in connecting portion 13 ends downwards.

Main part 11 comprises first main part 110 that is positioned on the vertical direction and from second main part 111 of first main part, 110 1 lateral bucklings.Have kink 112 between first main part 110 and second main part 111, this kink 112 is provided with the perforate 1120 that can reduce by first main part 110 and second main part, 111 stress, and this perforate 1120 also can increase the elasticity of kink 112.Above-mentioned elastic portion 12 is located at the top of first main part 110, this elastic portion 12 is to bending away from the direction bending of second main part 111 and then to close second main part, 111 directions, its end has the contact site 120 that contacts in the mode of pushing with chip module, contact site 120 is positioned at online always with the projection of elastic portion 12 at horizontal plane, does not have skew.The end of first main part 110 is connected with connecting portion 13, the connecting portion 13 and first main part 110 are in same vertical plane, this connecting portion 13 is made up of two linking arms arranged side by side 131, the position of connecting portion 13 is lower than the position of described kink 112, be connected with weld part 14 at linking arm 131 ends, it is vertical with linking arm 131 that this weld part 14 is tabular.Because contact site 120 is positioned at same linear direction with weld part 14, when chip module crimping conducting terminal 10, conducting terminal 10 can have well that elastic force is electrically connected with chip module.The angle that has acute angle between described second main part 111 and first main part 110, the 111 rectangular settings of second main part are provided with some hangnails 1110 so that conducting terminal 10 is fixed in the electric connector in these second main part, 111 both sides.Second main part, 111 bottoms are provided with the guide portion 1111 of guiding conducting terminal 10 assemblings.

Emphasis structure of the present utility model is: have additional the connecting portion 13 with two linking arms 131 between weld part 14 and the main part 11, these two linking arms 131 make when conducting terminal 10 electrically conducts to be in connecting portion 13 positions and are arranged in parallel, thereby have reduced the resistance and the inductance of conducting terminal 10; And be connected the bonding strength that can guarantee main part 11 and weld part 14 junctions with weld part 14 by two linking arms 131.

Below only be preferred embodiment of the present utility model, other any improvement conversion of being done on the present embodiment basis also should not break away from the technical solution of the utility model.
