請參閱第二圖、第六圖所示，本實施方式中，前述對接電子模組可採用DDR4電子模組，相對於先前之DDR3電子模組，DDR4電子模組下側之金手指數量增加以擴展對接電子模組之記憶體，同時可增加信號傳輸速度，而DDR4電子模組之底緣中間部分比兩端部分凸出，可降低***阻力，惟，DDR4電子模組***後會由於前述中間凸出之底緣結構而發生擺動。本發明之絕緣本體1兩端自中央插槽101底側凸伸有台階部102，該台階部102支撐於該對接電子模組較低之位置，以補償對接電子模組與絕緣本體之間的間隙，可防止DDR4電子模組擺動，且DDR4電子模組之底緣處的高度差小於或等於該台階部102之高度，以保證將對接電子模組墊起，防止晃動之效果較好；但是台階部102之最大高度需保證對接電子模組之金手指與導電端子正常電性接觸，即台階部102支撐後之對接電子模組的金手指到中央插槽底側之距離小於或等於導電端子之接觸部到中央插槽底側的距離；所述偵測端子組4之高度高於台階部102，以保證對接電子模組仍然能夠抵壓到前述偵測端子組4之抵接部423。 Referring to FIG. 2 and FIG. 6 , in the embodiment, the docking electronic module can adopt a DDR4 electronic module. Compared with the previous DDR3 electronic module, the number of gold fingers on the lower side of the DDR4 electronic module is increased. Expanding the memory of the docking electronic module, and increasing the signal transmission speed, and the middle portion of the bottom edge of the DDR4 electronic module is protruded from the two ends to reduce the insertion resistance. However, the DDR4 electronic module is inserted due to the aforementioned intermediate The bottom edge structure of the protrusion is oscillated. A step portion 102 is protruded from the bottom side of the central slot 101 at the two ends of the insulative housing 1 of the present invention. The step portion 102 is supported at a lower position of the docking electronic module to compensate for the connection between the docking electronic module and the insulative housing. The gap prevents the DDR4 electronic module from swinging, and the height difference at the bottom edge of the DDR4 electronic module is less than or equal to the height of the step portion 102, so as to ensure that the docking electronic module is padded to prevent sloshing; The maximum height of the step portion 102 is required to ensure normal electrical contact between the gold finger of the docking electronic module and the conductive terminal, that is, the distance between the gold finger of the docking electronic module supported by the step portion 102 to the bottom side of the central slot is less than or equal to the conductive terminal. The distance from the contact portion to the bottom side of the central slot; the height of the detecting terminal group 4 is higher than the step portion 102 to ensure that the docking electronic module can still be pressed against the abutting portion 423 of the detecting terminal group 4.

With respect to the first embodiment, the structure of the detecting terminal group 8 of the present embodiment and the insulating body 5 are provided on the latching member 7 and the at least one detecting terminal group 8 in the insulative housing 1; The location of the above is different. The following mainly explains the differences.
所述絕緣本體5具有收容對接電子模組400之中央插槽501、凸伸設置於中央插槽501內之鍵扣51，以與對接電子模組對應設置之槽口相配合，所述偵測端子組8係固持於中央插槽501底側之絕緣本體內，且位於鄰近前述鍵扣51之位置，可利用卡緣連接器既有結構，以節省偵測端子組8所佔用之空間；所述偵測端子組8包括相對設置且相配合之第一偵測端子81、第二偵測端子82，兩者可相對運動而實現相互接觸或相互分離，所述絕緣本體5形成有對應收容兩偵測端子之收容槽52，該收容槽52與前述中央插槽501相連通，以使得偵測端子組8與對接電子模組之間實現電性接觸。所述第二偵測端子82之結構與第一實施方式大致相同，而所述第一偵測端子81成倒置之「L」形，且抵靠於收容槽52內側，可穩固定位於收容槽52內，且第一偵測端子81及第二偵測端子82於垂直所述縱長方向的平面內相對設置，該第一偵測端子81一端具有與第二偵測端子82相接觸之第二接觸部811，第二偵測端子82具有自收容槽52內貫穿中央插槽501底側並凸伸入中央插槽501內以供對接電子模組抵壓之抵接部821、自該抵接部821進一步延伸至末端之第三接觸部822，該第三接觸部822係用於與第二接觸部811電性接觸。所述第二偵測端子82之第三接觸部822可依靠自身彈性而向上變形，並抵靠於第一偵測端子81之第二接觸部811下 側，而第二接觸部811之位移被絕緣本體5對應設置之擋止部511所限制，從而可防止第三接觸部822在未受外力之狀況下過度向上變形。 The insulative housing 5 has a central slot 501 for receiving the docking electronic module 400 and a button 51 protrudingly disposed in the central slot 501 for cooperating with a slot corresponding to the docking electronic module. The terminal group 8 is fixed in the insulating body on the bottom side of the central slot 501, and is located adjacent to the button 51. The card edge connector can be used to save the space occupied by the detecting terminal group 8; The detecting terminal group 8 includes a first detecting terminal 81 and a second detecting terminal 82 which are oppositely disposed and matched with each other so as to be in contact with each other or separated from each other. The insulating body 5 is formed with a corresponding receiving body. The receiving slot 52 of the detecting terminal is in communication with the central slot 501 to enable electrical contact between the detecting terminal set 8 and the docking electronic module. The structure of the second detecting terminal 82 is substantially the same as that of the first embodiment, and the first detecting terminal 81 is in an inverted "L" shape and abuts against the inner side of the receiving slot 52, and can be stably fixed in the receiving slot. The first detecting terminal 81 and the second detecting terminal 82 are oppositely disposed in a plane perpendicular to the longitudinal direction, and one end of the first detecting terminal 81 has a contact with the second detecting terminal 82. The second detecting portion 811 has a second detecting terminal 82 having an abutting portion 821 extending from the bottom of the central slot 501 and extending into the central slot 501 for receiving the docking electronic module. The connecting portion 821 further extends to the third contact portion 822 of the end, and the third contact portion 822 is for electrically contacting the second contact portion 811. The third contact portion 822 of the second detecting terminal 82 can be deformed upward by its own elasticity and abuts against the second contact portion 811 of the first detecting terminal 81. The displacement of the second contact portion 811 is restricted by the correspondingly disposed stopper portion 511 of the insulating body 5, so that the third contact portion 822 can be prevented from being excessively deformed upward without being subjected to an external force.
當對接電子模組***之前，第二接觸部811、第三接觸部822相互接觸，所述第三接觸部822位於第二接觸部811之下方，以便抵接部821受壓後帶動第三接觸部822離開第二接觸部811；所述第二偵測端子82之抵接部821係高出於中央插槽501之底側面502，可為第二偵測端子82提供足夠之位移空間，且所述抵接部821係位於第三接觸部822之上方，便於對接電子模組400***時先碰到抵接部821。當對接電子模組400***並向下抵壓前述抵接部821，第二偵測端子82彈性變形，第三接觸部822隨著抵接部821移動而離開第一偵測端子81，直到第二接觸部811、第三接觸部822相互分離。所述第一偵測端子81、第二偵測端子82可與前述LED燈所在之電子線路形成串聯電路或並聯電路，當該電子線路係採用串聯電路時，第一偵測端子81、第二偵測端子82作為控制串聯電路是否連通之偵測開關，兩者接觸時，可使得印刷電路板上之LED燈電子線路連通，LED燈亮，以提示對接電子模組未***，反之兩者分離，則LED燈不亮，則提示對接電子模組已***到位，此方案可定義為LED燈常亮方案；當前述第一偵測端子81、第二偵測端子82與LED燈所在之電子線路形成並聯電路時，所述LED燈所在線路形成一個分路，第一偵測端子81、第二偵測端子82形成可使LED燈短路之另一分路，使得第二接觸部811、第三接觸部822相互接觸時，LED燈所在線路發生短路，以提示對接電子模組未***，另，第二、第三接觸部作為前述另一分路之開關，並處於斷開狀態時，LED燈所在分路連通，由不亮變為發亮狀態，從而 提示對接電子模組***到位。 Before the docking electronic module is inserted, the second contact portion 811 and the third contact portion 822 are in contact with each other, and the third contact portion 822 is located below the second contact portion 811, so that the abutting portion 821 is pressed to drive the third contact. The second detecting portion 811 is separated from the second contact portion 811; the abutting portion 821 of the second detecting terminal 82 is higher than the bottom side surface 502 of the central slot 501, and provides sufficient displacement space for the second detecting terminal 82, and The abutting portion 821 is located above the third contact portion 822 to facilitate the first contact of the abutting portion 821 when the docking electronic module 400 is inserted. When the docking electronic module 400 is inserted and pressed down against the abutting portion 821, the second detecting terminal 82 is elastically deformed, and the third contact portion 822 moves away from the first detecting terminal 81 as the abutting portion 821 moves until the first The two contact portions 811 and the third contact portions 822 are separated from each other. The first detecting terminal 81 and the second detecting terminal 82 can form a series circuit or a parallel circuit with the electronic circuit where the LED lamp is located. When the electronic circuit adopts a series circuit, the first detecting terminal 81 and the second detecting terminal The detecting terminal 82 is used as a detecting switch for controlling whether the series circuit is connected. When the two are in contact, the electronic circuit of the LED lamp on the printed circuit board can be connected, and the LED light is bright to indicate that the docking electronic module is not inserted, and the two are separated. If the LED light is off, it indicates that the docking electronic module has been inserted into the position. The solution can be defined as the LED light-on scheme; when the first detecting terminal 81, the second detecting terminal 82 and the LED light are formed, the electronic circuit is formed. When the circuit is connected in parallel, the line where the LED lamp is located forms a branch, and the first detecting terminal 81 and the second detecting terminal 82 form another branch that can short-circuit the LED lamp, so that the second contact portion 811 and the third contact are When the parts 822 are in contact with each other, the line of the LED light is short-circuited to indicate that the docking electronic module is not inserted, and the second and third contact parts are used as the switches of the other branch, and when the LED is in the off state, the LED light is located. Split Connected, from no light to bright, thus The docking electronics module is inserted into place.
反之，當對接電子模組***後需要退出時，對接電子模組被退出，第二接觸部811、第三接觸部822恢復原本狀態而相互接觸；若採用前述常亮方案，此時LED燈由不亮變亮，提示對接電子模組開始退出；若採用前述常閉方案，此時LED燈由亮變不亮，提示對接電子模組開始退出。 On the other hand, when the docking electronic module needs to be withdrawn after being inserted, the docking electronic module is withdrawn, and the second contact portion 811 and the third contact portion 822 are restored to each other and contact each other; if the aforementioned constant light scheme is adopted, the LED light is If the light is off, it indicates that the docking electronic module starts to exit; if the above-mentioned normally closed scheme is adopted, the LED light is turned on or off at this time, indicating that the docking electronic module starts to exit.
本發明卡緣連接器通過偵測端子組4、8之第二接觸部、第三接觸部相互接觸或分離，而使得相連接之印刷電路板上的LED在發亮或不亮狀態之間轉換，以檢測對接電子模組是否插置到位，便於使用者觀察而進行插拔操作。 The card edge connector of the present invention switches the LEDs on the connected printed circuit board between bright or non-bright state by detecting that the second contact portion and the third contact portion of the terminal groups 4, 8 are in contact with or separated from each other. To detect whether the docking electronic module is inserted in place, and it is convenient for the user to observe and perform the plugging operation.
