Description

Arrangements of electric connection

Technical field

The utility model relates to a kind of arrangements of electric connection, particularly relates to a kind of arrangements of electric connection that reduces height.

Background technology

Consult Fig. 1, the Taiwan is invented No. 257196 patent case and is disclosed a kind of arrangements of electric connection 1, and this arrangements of electric connection 1 comprises one and is electrically connected on first electric connector 12 and on the first circuit board 11 and is electrically connected on second electric connector 14 on the second circuit board 13.This known purpose is to eliminate first, second electric connector 12,14 when being electrically connected because of position or strain that alignment error caused, so in second insulation shell 141 of second electric connector 14, be provided with two deflection spaces 142, so that the attenuation part 144 of second conducting terminal 143 lays respectively in the deflection space 142, then when first, second electric connector 12, during 14 butt joints, if first, second circuit board 11,13 have site error or alignment error, the part 144 of second conducting terminal, 143 attenuation can produce deflection to sponge error in deflection space 142, therefore can prevent first, second electric connector 12, each assembly distortion of 14.

But, because second insulation shell 141 must be provided with deflection space 142, so second insulation shell 141 can increase height d ₁, and cause the distance of 11,13 of first, second circuit boards to increase, then arrangements of electric connection 1 just can't be designed to low clearance (low-profile) and reduces occupation space.

Even if known have a part that wears a perforation 131 ccontaining second insulation shells 141 on second circuit board 13, also can only reduce because of distance that 11,13 of first, second circuit boards that deflection space 142 increases are set (d highly ₁), but the height d can't reduce by second insulation shell 141 deflection space 142 is not set the time ₂So the known distance that can't effectively reduce 11,13 of first, second circuit boards still can make arrangements of electric connection 1 take a lot of spaces.And, the perforation 111 of this mode on original first circuit board 11, certainly will establish a perforation 131 again at second circuit board 13, these second circuit board 13 spendable areas are reduced, and the inconvenience in the design (for example the configuration (layout) of cabling (trace) must be walked around perforation 131).

The utility model content

Therefore, the purpose of this utility model is that a kind of arrangements of electric connection that can effectively reduce height between board to board connector when butt joint two circuit boards is being provided.

Arrangements of electric connection described in the utility model comprises first circuit board, first electric connector (socket), second circuit board, and second electric connector (plug).

First circuit board comprises first, in contrast to this first second, and the opening that runs through this first, second face.

First electric connector is positioned on first of this first circuit board, and comprise first insulation shell and many first conducting terminals, this first insulation shell has a plurality of the first terminal grooves, all the first terminal grooves all with the open communication of this first circuit board, described first conducting terminal is individually fixed in each the first terminal groove and with this first circuit board and is electrically connected.

Second electric connector is positioned on this second circuit board, and comprise second insulation shell and many second conducting terminals, this second insulation shell has a body, two teats of being given prominence to by the down either side side direction of this body respectively, and a plurality of second terminal grooves that run through this body, the cross section of this body is less than the cross section of the opening of this first circuit board, the end face of each teat is lower than the end face of this body, and described second conducting terminal is individually fixed in each second terminal groove and with this second circuit board and is electrically connected.

When second electric connector when second of first electric connector pegs graft, the part of the body of second insulation shell is arranged in the opening of first circuit board, and second of the end face of these two teats and first circuit board contacts, at this moment, second conducting terminal lays respectively in each the first terminal groove and is electrically connected with corresponding first conducting terminal.

Effect of the present utility model is that end face that first circuit board is provided with the teat of the opening and second insulation shell is lower than the end face of body, when then first, second electric connector is electrically connected, the part of the body of second insulation shell can be arranged in the opening of first circuit board, so the distance between first, second circuit board only is subject to the height of the teat of second insulation shell, therefore, effectively reduce height between first, second circuit board.And, compare with known, opening need be set on the second circuit board of the present utility model, and only need be provided with opening on first circuit board, can reduce the distance between first, second circuit board, and teat can be designed to extremely thin (known technology can't be accomplished), so that the distance between first, second circuit board is very approaching.
