With reference to Fig. 3 to Fig. 6, each said conducting terminal 3 has a base portion 31 correspondences and is contained in each said accepting hole 20, and said base portion 31 is a tabular, and is and vertically is arranged in the said accepting hole 20.

Be extended with a weld part 32 from said base portion 31 lower ends, said weld part 32 extends to form to bending from said base portion 31 lower end side, is tabular, and is positioned at the same side of said base portion with said two elastic arms.Said weld part 32 is fixedly welded on said first conduction region 10, to realize mechanical connection and the electric connection between said conducting terminal 3 and the said main circuit board 1.From said weld part 32 away from an end of said base portion 31 upwards bending be extended with a location division 35; The said conducting terminal 3 in 35 location, said location division is in said accepting hole 20, and said location division 35, said base portion 31 and said weld part 32 threes form the U type jointly.Extended upward a holding section 36 in said location division 35, the width of said holding section 36 is greater than the width of said location division 35, and the said support slot 21 that said holding section 36 gets in the said insulating body 2 positions.

35 place lateral bucklings are extended with two elastic arms 33 towards said location division from said base portion 31 upper ends, center between said two elastic arms 33 to form a grasping part 34.

Said insulated substrate 4 is positioned at said insulating body 2 tops; Said insulated substrate 4 corresponding a plurality of said accepting holes 20 have provided a plurality of storage tanks 40; Each said conductive pin 5 has a fixed part 51 correspondences and is positioned in the said storage tank 40; Be provided with the below that a Plug Division 52 is revealed in said insulated substrate 4 from said fixed part 51 to extending below, and extend upward from said fixed part 51 and to be provided with the top that a junction 53 is revealed in said insulated substrate 4.The bottom of said Plug Division 52 has one of rounding off and connects face 520, inserts in the said grasping part 34 smoothly in order to guide said Plug Division 52, and said two elastic arms 33 have a bite 330 respectively and contact with said Plug Division 52.

Said flexible PCB is positioned at said insulated substrate 4 tops; The lower surface of said flexible PCB is provided with a plurality of second conduction regions 60; Said second conduction region 60 is fixed by welding between the said connecting portion 53 of said conductive pin 5, with mechanical connection and the electric connection that realizes the two.

The utility model electrical connection module installation process is following: earlier said insulating body 2 is installed on the said main circuit board 1; Make the said conducting terminal 3 of said accepting hole 20 aim at said first conduction region 10, and the said weld part 32 of said conducting terminal 3 is fixedly welded on said first conduction region, 10 upper surfaces; Again said conductive pin 5 is planted and be fixed on the said insulated substrate 4, and said connecting portion 53 is fixedly welded on said second conduction region, 60 lower surfaces of said sub-circuit board 6, obtain structure as shown in Figure 5 this moment; At last; Only need the said Plug Division 52 of said conductive pin 5 is aimed at and inserted in the said grasping part 34 that said two elastic arms 33 of said conducting terminal 3 form (as shown in Figure 6), just can realize the mechanical connection and the electric connection of said sub-circuit board 6 and said main circuit board 1.

The utility model is electrically connected module and has following beneficial effect:

1. owing to said two elastic arms 33 extend to form from said base portion 31 side direction bending; Therefore; The height that whole said conducting terminal 3 takies is less; Consider the height when said elastic arm 33 is not pressed down need not in prior art, thereby can reduce the thickness of said insulating body 2 and even whole said electrical connection module; In addition; Said two elastic arms 33 have better elastic and uphold and restoring force; Help said conductive pin 5 in said grasping part 34 insertion and extract, and then help the operation that electrically conducts and electrically disconnect between said sub-circuit board 6 and the said main circuit board 1.

2. owing to said two elastic arms 33 extend to form from said base portion 31 side direction bending; Said conductive pin 5 inserts in the said grasping part 34 and electrically contacts with said two elastic arms 33; Therefore, said electrical connection module only needs said conductive pin 5 is inserted in the said grasping part 34, more said sub-circuit board 6 is electrically contacted with said conductive pin 5; Can realize mechanical connection and electric connection between said main circuit board 1 and the said sub-circuit board 6; Need not extra clinching mechanism, can reduce element, save installation procedure, effectively saved production cost.

3. because the said base portion 31 of said conducting terminal 3 is a tabular; And vertically be provided with; Said base portion 31 need not have elasticity; Thereby the thickness of said insulating body 2 only need consider that the actual height of said base portion 31 gets final product, and practiced thrift the space to a certain extent, helps reducing the thickness of said insulating body 2.

4. contact with said conductive pin 5 owing to having a bite 330 respectively on said two elastic arms 33, compared with prior art, the mode of this 2 contacts is more firm, has improved the reliability that is electrically connected module.

5. because the said face 520 that connects of rounding off is arranged in the bottom of said Plug Division 52, can guide said conductive pin 5 to get into smoothly in the said grasping parts 34 between said two elastic arms 33, make things convenient for the insertion of said conductive pin 5 and extract.

Since said weld part 32 from said base portion 31 lower end side to being bent to form; Thereby the kink branch between said base portion 31 and the said weld part 32 has certain elasticity; When said conductive pin 5 presses down when getting into said grasping part 34 and contacting with said two elastic arms 33; This bending part can cushion the downforce that said conducting terminal 3 is received, thereby protects said conducting terminal 3, prolongs its useful life; In addition, said weld part 32 is positioned at a side of said base portion 31, and the not extra height that takies, thereby can further reduce the thickness of said insulating body 2, help being electrically connected module towards thinner mode development.

7. because said weld part 32 is a tabular, can designs and be identical with said first conduction region, 10 general size, the welding that helps between itself and said first conduction region 10 is fixed; Because said weld part 32 and said two elastic arms 33 are positioned at the same side of said base portion 31, therefore can save 3 of said conducting terminals and take up space.

8. because the common U type structure that forms of said location division 35, said base portion 31 and said weld part 32 threes can further cushion the downforce that said conducting terminal 3 is received, said conducting terminal 3 is played a good protection.

Since the width of said holding section 36 greater than the width of said location division 35; And said support slot 21 cooperates said holding section 36; Thereby said conducting terminal 3 can be positioned in the said accepting hole 20 securely, and said conductive pin 5 is not easy to drive said conducting terminal 3 when between said two elastic arms 33, extracting and skids off said insulating body 2.

More than specify the explanation of the preferred embodiment that is merely the utility model; Non-thus the limitation the utility model claim; So the equivalence techniques that all this creation of utilization specifications and diagramatic content are done changes, and all is contained in the claim of the utility model.
