Description
The relevant a kind of electronic card coupler of the utility model especially refers to a kind of electronic card coupler with less entire length.
Electronic card coupler is widely used in the portable electronic devices such as notebook computer and palmtop computer, is used for realizing that the signal between electronic cards and circuit board transmits.Relevant prior art sees also United States Patent (USP) the 5th, 601, cases such as No. the 84206174th, No. 438 cases, TaiWan, China patent application and No. 84206175.The structure of existing electronic card coupler as shown in Figure 1, this electronic card coupler 7 comprises insulating body 71 and two rows conducting terminal 72,73 arranged side by side, wherein insulating body 71 is provided with some accepting hole 711,712 correspondences and holds above-mentioned conducting terminal 72,73.Conducting terminal 72,73 all has fixed part 72a, the 73a that is housed in the above-mentioned accepting hole 711,712, and this fixed part 72a, 73a one end extend insulating body 71 and form and dock contact site 72b, the 73b that electronic cards (not shown) electrically connects.The other end of fixed part 72a, 73a is bent into afterbody 72c, 73c downwards, and afterbody 72c, 73c are welded on the related circuit plate 8, is used for electrically connecting with circuit board 8.
But, afterbody 72c, the 73c of the conducting terminal 72,73 of this electronic card coupler 7 all is positioned at a side of insulating body 71, for fear of influencing its manufacturing because of distance is too near between the difference row conducting terminal 72,73, so the fixed part 72b prolongation of conducting terminal 72 is bent into afterbody 72c afterwards for one section again.Like this, the entire length of electronic card coupler 7 is bigger, so will take the bigger inner space of electronic installation, this obviously is unfavorable for the short and smallization design of portable electronic devices.Therefore this electronic card coupler has improved necessity.
The purpose of this utility model is to provide a kind of electronic card coupler, and the conducting terminal of this electronic card coupler can be stablized and is retained in the insulating body, and insulating body has less length, thereby its area shared on circuit board is less.
The purpose of this utility model is achieved in that electronic card coupler comprises insulating body and is housed in some first, second conducting terminals in the insulating body, and wherein insulating body has the interface that contacts with the butt joint electronic cards and towards the composition surface of circuit board.First, second conducting terminal is provided with and extends interface and the butt joint contact site that electrically connects of electronic cards and extend the afterbody that composition surface and related circuit plate electrically connect downwards by contact site, the fixed part that wherein has downward extension on the contact site of first conducting terminal, and has upwardly extending fixed part on the contact site of second conducting terminal, said fixing portion all is housed in the set fixing hole of insulating body, is used for first, second conducting terminal is fixed on the insulating body.
Because adopt said structure, the insulating body of the utility model electronic card coupler has less length, thereby its area shared on circuit board is less, and its conducting terminal can be stablized and is retained in the insulating body.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the cutaway view of existing electronic card coupler and the assembling of related circuit plate.
Fig. 2 is the three-dimensional exploded view of the utility model electronic card coupler and related circuit plate.
Fig. 3 is the sectional block diagram of insulating body in the utility model electronic card coupler.
Fig. 4 is the cutaway view after the utility model electronic card coupler is combined in circuit board.
See also Fig. 2 and shown in Figure 3, the utility model electronic card coupler 1 comprises insulating body 20, two rows, first conducting terminal 31, second conducting terminal 32 and holding body 60 arranged side by side, and wherein insulating body 20 has the interface 25 that contacts with butt joint electronic cards (not shown) and towards the composition surface 26 of circuit board 4.First receiving space 21 that upper surface 28 relative with above-mentioned interface 25 and composition surface 26 and front surface 29 are provided with connection, and in position be provided with the fixing holes 22 that oppositely extend towards upper surface 28.Composition surface 26 is provided with second receiving space 23 in the side near interface 25, and it extends fixing hole 24 towards upper surface 28.First, second conducting terminal 31,32 is equipped with and extends interface 25 and dock contact site 31a, the 32a that electronic cards electrically connects, wherein first conducting terminal 31 has the afterbody 31b and the fixed part 31c of downward extension, afterbody 31b partly is housed in above-mentioned first receiving space 21, and extend composition surface 26, and be soldered on the circuit board 4.Second conducting terminal 32 has the afterbody 32b and the upwardly extending fixed part 32c of downward extension, and this afterbody 32b extends composition surface 26 downwards, and is soldered on the circuit board 4.The 31c of said fixing portion, 32c are housed in the fixing hole 22,24, are used for first, second conducting terminal 31,32 is fixed on the insulating body 20.Fixed part 31c, 32c are provided with double wedge 311,321, are used for further first, second conducting terminal 31,32 being fixed on the insulating body 20.In addition, insulating body 20 has the holding hole 27 of the leading edge of being arranged on, and by above-mentioned holding body 60 insulating body 20 is retained on the circuit board 4.
See also Fig. 2 and shown in Figure 4, during assembling, the fixed part 31c of first conducting terminal 31 is inserted into the fixing hole 22 from insulating body 20 tops, contact site 31a and afterbody 31b partly are housed in first receiving space 21.And the fixed part 32c of second conducting terminal 32 is inserted into the fixing hole 24 from insulating body 20 belows, contact site 32a and afterbody 32b partly are housed in second receiving space 23.At this moment, double wedge 311,321 and insulating body 20 interfered, and prevent first, second conducting terminal 31,32 with dock the electronic cards docking operation in from insulating body 20, come off.Holding body 60 passes the holding hole 27 of insulating body 20 and is installed in the corresponding accepting hole 41 of circuit board 4 then, and then insulating body 20 is retained on the circuit board 4.At last, afterbody 31b, the 32b of first, second conducting terminal 31,32 are welded on the circuit board 4 circuit board 4 and electronic card coupler 1 usefulness surface soldered technology.Because above-mentioned afterbody 31b, 32b lay respectively at the both sides of insulating body 20, so in the process of design and manufacturing, needn't consider too closely to influence because of distance between first, second conducting terminal 31,32 problem of its manufacturing property.Therefore, one does not need to prolong laterally one section distance that strengthens between the two among afterbody 31b or the 32b, thereby can shorten the entire length of electronic card coupler 1, and then reduces the area that it takies circuit board 4.In addition, because fixed part 31c, 32c are inserted in the fixing hole 22,24 by vertical direction, and first, second conducting terminal 31,32 only is subjected to cross force in butt joint electronic cards grafting process, so first, second conducting terminal 31,32 of electronic card coupler 1 can not come off from insulating body 20 in docking operation, thereby can reach highly stable fixing effect.
