Embodiment
Above-mentioned and the other technologies content that this is novel, characteristics and effect can be known understanding in the detailed description of the preferred embodiment of following conjunction with figs. formula.
At first shown in Fig. 2,3, show first preferred embodiment of the board to board connector 1 that the utlity model has positioning action among the figure, it mainly comprises an insulating body 2, a holder 3 and a plurality of conducting terminal 4, with so that form between a main circuit board 5 and the sub-circuit board 6 and be electrically connected.Sub-circuit board 6 is a wireless telecommunications wafer module in the present embodiment, its be a rectangle plate body and have two long to side 61, thereby the length centre indent of each side 61 forms a long rectangular indentation 611, and each has a plurality of Copper Foil conductive junction points (pad) 612 along its protruding dew in length direction interval in breach 611 both sides sides 61 bottoms.In other were used, sub-circuit board 6 also can be used as other purposes, and is not limited to the pattern that present embodiment is enumerated.
Insulating body 2 is to cooperate the size of sub-circuit board 6 sides 61 roughly to be a lengthwise shape and slightly flat cuboid, it has oppositely and all is an end face 21 and a bottom surface 22 of level, and at 22 vertically extending fronts 23 of end face 21 and bottom surface and a back 24 (with reference to figure 1).3 positions that are engaged in sub-circuit board 6 breach 611 of holder, body 2 length that insulate certainly upwards protrude out certain-length to centre end face 21 rear sides, and integrally formed as same dielectric materials such as plastic cement with insulating body 2.Yet in other modified examples, holder 3 also can be made of metal the back and be assembled into insulating body 2 by any known method, has the shielding action that prevents electromagnetic interference (EMI) simultaneously.
Need point out, though holder 3 is an example to be positioned at insulating body 2 length direction centre in the present embodiment, but also can be positioned at insulating body 2 length directions, two outsides or other appropriate locations, or extend and isometric with insulating body 2 along insulating body 2 length directions, these modification all belong to this novel scope.
Shown in Fig. 2,3, cooperate sub-circuit board 6 sides 61 conductive junction points 612 positions for another example, insulating body 2 length directions two symmetrical outside are spaced apart to be provided with a plurality of terminal slots 26, so that each conducting terminal 4 plugs.Each terminal slots 26 is offered certain depth backward from body 2 fronts 23 of insulating, 4 mating terminals slot 26 sizes of conducting terminal, extend insulating body 23 bottoms, 2 fronts so that the main circuit board 5 corresponding contacts weld part 41 of (figure does not show) is located in weldering and have, one extends the base portion 42 that is fixed in terminal slots 26 root edges backwards from weld part 41, one from oblique forward first kink 43 of going up bending of base portion 42, one from the extension of first kink, 43 front ends and with more large-angle inclined second kink 44 of going up bending, and the contact site 45 of a downward bending after second kink 44 extends, and contact site 45 convex insulating body 2 end faces 21 that are exposed to connect so that the conductive junction point 612 of sub-circuit board 6 correspondences presses.
Use installing step of the present utility model is as follows, at first as shown in Figure 2, with 6 liang of breach 611 of paired connector 1 corresponding sub-circuit board, be fixed on the precalculated position of main circuit board 5 with its two fronts, 23 relative directions, each connector 1 is connected to main circuit board 5 with its bottom surface 22, and main circuit board 5 is located in weld part 41 welderings of conducting terminal 4.Then as shown in Figure 5, breach 611 places of sub-circuit board 6 dual-sides 61 are pressed against the inclined-plane 312 of each holder 3 downwards and glide along the inclined-plane, 3 outside deflections of each holder simultaneously launch, glide by inclined-plane 312 minimum points until breach 611 places of sub-circuit board 6, shown in Fig. 5,6, make holder 3 inside elastic deflections and sub-circuit board 6 breach 611 place sides 61 are clamped between clamping face 311 and insulating body 2 end faces 21.Simultaneously, constitute electrical connection thereby 612 of the conductive junction points of sub-circuit board 6 are pressed against each corresponding conducting terminal 4 contact site 45, and conducting terminal 4 is slightly descended because of stressed bending whole height.Otherwise, upwards withdraw from the process of each holder 3 about sub-circuit board 6, holder 3 also will be in like manner outwards deflection launch so that sub-circuit board 6 is broken away from, its details is not given unnecessary details in addition at this.
In second embodiment shown in Figure 8, the orthogonal side 61 of two couple of sub-circuit board 6 ', 62 ' on the length centre all indent and respectively form a long rectangular indentation 611 ', 612 ', and each breach 611 ', 612 ' both sides side 61 ', all protruding dew in 62 ' bottom has conductive junction point (figure does not show).Connector 1 ' then corresponding to 6 ' two pairs of breach 611 of sub-circuit board ', 612 ' position, and fixedly be in opposite directions in pairs main circuit board 5 ' on, so that common 6 ' two pairs of breach 611 of clamping sub-circuit board ', 612 ', and make sub-circuit board 6 ' be electrically connected with main circuit board 5 ' generation.
By above-mentioned structure, the utility model provides a kind of novelty and has multi-functional board to board connector, it is except making being electrically connected between sub-circuit board and main circuit board, and the firm clamping locator circuit board of energy, its unlikely any deflection is become flexible and being electrically conducted between influence and the connector, and its operating process is also extremely easy.Have again, demonstrate as the difference of above-mentioned two embodiment, the lateral location that connector also can cooperate the sub-circuit board conductive junction point to be provided with, and carry out corresponding elasticity configuration.
The above; it only is preferred embodiment of the present utility model; can not limit the scope that the utility model is implemented with this, every simple equivalent of doing according to the utility model claim and creation description changes and modifies, and all should belong in the protection range of the present utility model.
