Description

Electronic card coupler

The utility model is about a kind of electronic card coupler, refers in particular to a kind of electronic card coupler that is used to realize electronic cards and circuit board electric connection.

Along with light, thin, short, the little development trend of portable computer and to the continuous increase of new functional requirement, usually need to rely on more plug-in extension device and with electronic cards as coffret, this electronic cards can be accommodated and be electrically connected in the electronic card coupler of portable computer.This electronic card coupler can be the form of bilayer even multilayer.Correlation technique sees also cases such as No. the 84206174th, the 5th, 601, No. 438 patents of the U.S., tw Taiwan patent application and No. 84206175.

As shown in Figure 1, existing electronic card coupler 1 comprises that upper and lower two respectively are used to accommodate the insulating body 10 of the receiving space 110,120 of an electronic cards, insulating body respectively runs through in the position of contiguous each receiving space and is provided with two row's terminal accommodation holes 111,121, and two ranked first conducting terminal 11 and be arranged in the terminal accommodation holes 111, and stretch in the receiving space 110, two ranked second conducting terminal 12 is located in the terminal accommodation holes 121, and stretches into down in the receiving space 120.The part that conducting terminal 11,12 stretches into receiving space 110,120 is to form the contact site 112,122 that electrically conducts with electronic cards, its other end then is bent to form junction surface 113,123 downwards, and junction surface 113,123 can be run through the respective through hole 80 of circuit board 8 and be electrically connected to this circuit board 8.

But, the conducting terminal 11,12 of this electronic card coupler 1 all is to insert the accepting hole 111,121 from a side of insulating body 10, and its junction surface 113,123 all is in the same side of insulating body 10, touch mutually when avoiding different row's conducting terminals 11,12 to electrically connect, have to make in the horizontal direction first conducting terminal 11 to extend one section ratio, second conducting terminal, 12 longer length and be bent into junction surface 113 afterwards again with the related circuit plate.Therefore, the overall length on double-deck electronic card coupler 1 horizontal direction of this kind will increase much than the length of individual layer electronic card coupler, thereby has taken assembling area bigger on the circuit board, is unfavorable for the miniaturization development of electronic installation.In addition, the junction surface 113,123 of all conducting terminals 11,12 all extends in the same side of electronic card coupler 1, and during as if employing SMT processing procedure, the junction surface of internal layer will be difficult to welding, be unfavorable for the weld job of junction surface on circuit board.

The purpose of this utility model is to provide a kind of compact conformation and conducting terminal to be beneficial to the electronic card coupler that is welded on the circuit board when adopting the SMT processing procedure.

The purpose of this utility model is achieved through the following technical solutions: this electronic card coupler comprises insulating body and is housed in some first in the insulating body, second conducting terminal, wherein insulating body is provided with at least one receiving space of accommodating electronic cards and plurality of terminals accepting hole, and first, in two conducting terminals are planted the respective terminal accepting hole from the insulating body both sides respectively, and respectively be provided with to extend to and be used in the receiving space and dock the contact site that electronic cards realize to electrically connect, with the fixed part of respective terminal accepting hole secure bond and be electrically connected to junction surface on the circuit board.

Compared with prior art, advantage of the present utility model is: the other places, bonding part of conducting terminal are in the both sides of insulating body, therefore in design and manufacture process, when different rows' conducting terminal and related circuit plate electrically connect, the junction surface is to be distributed in respectively on the Width on forward and backward surface of insulating body, have bigger spacing thereby make between the junction surface of terminal, and can not produce problem interfering with each other, that touch.Simultaneously, first conducting terminal needn't extend one section longer length of ratio second conducting terminal in the horizontal direction, and is many thereby the entire length of existing double-deck electronic card coupler shortens, and helps the miniaturization development of electronic installation.In addition, the both sides of electronic card coupler are extended at the junction surface of first and second conducting terminal respectively, when adopting the SMT processing procedure, help the weld job of junction surface on circuit board.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
