Insulating body 1, it is a rectangle frame shaped structure, have a plug-in card space 10 and be located at first slot 11 of top in the insulating body 1 and be located at second slot 12 of below in the insulating body 1, dual-side is provided with guiding face 13 again in the place ahead in plug-in card space 10, this guiding face 13 helps this electronic cards (not shown) to be easier to insert in the plug-in card space 10, and in plug-in card space 10, be provided with a node 14, by this node 14, make this plug-in card space 10 be divided into two spaces that length is different, these node 14 positions cooperate the kenel of electronic cards, and electronic cards only can be inserted in this plug-in card space 10 with forward condition;

Plural number the first terminal 2, directly cut by sheet metal and to form, make the first terminal have base portion 21, contact site 22 and weld part 23, wherein, this contact site 22 is upwards bent and is extended forward by top, base portion 21 rear ends and forms, and this weld part 23 extends the back bending downwards by base portion 21 rear ends and forms;

Plural number second terminal 3, by the front-seat terminal 31 of plural number and plural number back row's terminal 32, this front row terminal 31 and back row's terminal 32 respectively have base portion 311 and 321, contact site 312 and 322 and weld part 313 and 323, second terminal 3 cuts bending more earlier by sheet metal and is formed, make second terminal 3 have better elastic force, wherein, this contact site 312 and 322 is by base portion 311, after 321 rear end bends upward and forwards extends to form first kink 314 and 324 again, bend upward again and forwards extend to form after second kink 315 and 325, end by second kink 315 and 325 upwards is bent to form contact site 312 and 322 again, make contact site 312 and 322 form the configuration of shell fragment, and has splendid elastic force, the weld part 313 of this front row terminal 31 extends back bending downwards more forward by base portion 311 front ends and forms, the weld part 323 of this back row's terminal 32 is directly bent downwards by base portion 321 front ends and forms, before described, back row's terminal 31,32 weld part 313,323 are all direct insertion pin, can be used to be inserted in the default jack of circuit board (not shown);

In addition, can install a pad 4 respectively in the both sides of insulating body 1 again, it forms for the metal material bending, is assembled in the default groove in insulating body 1 both sides.

Above-mentioned member is when assembling, plural the first terminal 2 is gone in first slot 11 by the rear group of insulating body 1, plural the first terminal 2 can be embedded in the insulating body 1, the then downward elastic extension of the contact site 22 of the first terminal 2 also protrudes in the plug-in card space 10, and then plural second terminal 3 gone in second slot 12 by the place ahead group of insulating body 1, plural second terminal 3 can be assembled in the insulating body 1, the contact site 312 of second terminal 3 and 322 protrude in respectively in the plug-in card space 10, the last both sides that again pad 4 are assembled in insulating body 1, can make insulating body 1 more firm being welded on the circuit board by pad 4, also finish assembling of the present utility model simultaneously.

Please consult Fig. 3 again to shown in Figure 5, be assembled sectional view of the present utility model, assembled sectional view during plug-in card and the assembled sectional view behind the plug-in card, as shown in the figure, the utility model is fixed on the lateral margin of circuit board 5, the place ahead in the plug-in card space 10 of this insulating body 1 has a guiding face 13, this guiding face 13 helps the mode of electronic cards 6 from bottom to top to tilt, plant is gone in the plug-in card space 10,61 of the contacts of electronic cards 6 front end upper and lower surfaces can compress the contact site 22 of the first terminal 2 and the contact site 312 of second terminal 3 simultaneously, 322 (in this figure, only showing 322), and then the other end of electronic cards 6 upwards lifted, make electronic cards 6 become level, the contact 61 of electronic cards 6 gets final product the contact site 312 stable and contact site 22 the first terminal 2 and second terminal 3,322 form electric connection, wherein, the contact site 322 of this second terminal 3 has the configuration that first kink 324 and second kink 325 form the shell fragment shape because of the bottom, make it have better elastic force, therefore when being subjected to the extruding force of electronic cards 6, can produce bigger reaction force, and can be more firm support on the contact 61 of electronic cards 6, with the clamping that electronic cards 6 is more stable, owing to itself have better elastic force, so more difficult generation elastic fatigue or distortion when stressed supporting, can prolong the useful life of second terminal 3 again on the other hand, and then make electrical transmission more smooth and easy and stable.

Please consult Fig. 6 again to shown in Figure 8, front view for another execution mode of the present utility model, the cutaway view of the cutaway view of Fig. 6 A-A line segment and Fig. 6 B-B line segment, as shown in the figure, second slot 12 of being located at insulating body of the present utility model 1 below is except can be Figure 1 and Figure 2 form arranged side by side to each other, also can be as shown in Figure 6, these second slots 12 are arranged for the mode of dislocation up and down, so can promote second slot 12 wall thickness each other, because this second slot 12 is the mode that misplaces up and down, so second slot 12 is divided into two-layer different height up and down again, therefore the form of front-seat terminal 31 is constant, it is higher because of its position then to arrange terminal 32, so after only bending first kink 324, end in first kink 324 upwards bends contact site 322 again, can make the contact site 312 of front-seat terminal 31 have identical height with the contact site 322 of back row's terminal 32, so that form electric connection with electronic cards (not showing in the present embodiment), can promote the intensity of insulating body 1 by said structure, make insulating body 1 in manufacturing process, can not deform or crooked situation.

The mode that bends again the utility model cuts plural second terminal with punching press after, make the contact site of plural second terminal form bending for several times and have better elastic force, so can promote the chucking power of plural second terminal and electronic cards, can avoid plural second terminal behind plug-in card repeatedly and produce elastic fatigue or distortion again, and then each terminal that can guarantee plural second terminal can both be stable really support on the contact of electronic cards so that more smooth and easy stable when electrically transmitting.

Above-mentioned detailed description is at a kind of preferable embodiments possible explanation of the present utility model, be not in order to limit claim of the present utility model, all other do not break away from the equalization of being finished under the skill spirit that the utility model discloses to be changed and modifies change, all should be contained in the claim that the utility model contains.
