參閱圖9至圖11，特別說明的是，本較佳實施例中，最左側的四個第一導電端子121分別為兩個接地端子121a和位於該兩個接地端子121a之間的兩個信號端子121b。這兩個信號端子121b組成一對差分信號端子對。Referring to FIGS. 9 to 11 , in particular, in this preferred embodiment, the four first conductive terminals 121 on the far left are two ground terminals 121 a and two signals located between the two ground terminals 121 a respectively. terminal 121b. The two signal terminals 121b constitute a pair of differential signal terminals.

主要參閱圖10及附帶參閱圖4，該信號端子121b的前部具有一第一接觸部1211b，該接地端子121a的中部位置處具有一第一接觸部1211a，該信號端子121b的第一接觸部1211b的最低點略微向下並略微向前超出該接地端子121a的第一接觸部1211a的最低點。該接地端子121a還從該第一接觸部1211a的前端進一步向前延伸出一第二接觸部1214，該第二接觸部1214相對於相鄰的該信號端子121b的第一接觸部1211b則位於更靠前的位置。Referring mainly to FIG. 10 and accompanying FIG. 4 , the front portion of the signal terminal 121b has a first contact portion 1211b, the middle position of the ground terminal 121a has a first contact portion 1211a, and the first contact portion of the signal terminal 121b The lowest point of 1211b is slightly downward and slightly forward beyond the lowest point of the first contact portion 1211a of the ground terminal 121a. The ground terminal 121a further extends forward from the front end of the first contact portion 1211a to extend a second contact portion 1214, and the second contact portion 1214 is located at a higher position relative to the first contact portion 1211b of the adjacent signal terminal 121b. forward position.

該信號端子121b的第一接觸部1211b以及該接地端子121a的第一接觸部1211a、第二接觸部1214均呈U型，且U型的開口方向均朝向上側（或是說背向該插槽1111）。在圖10所示的沒有額外施加壓力的自由狀態下，該信號端子121b的第一接觸部1211b的最低點較佳是略微低於該接地端子121a的第一接觸部1211a的最低點，而該第二接觸部1214的最低點相比於該第一接觸部1211a的最低點位於略高的水平位置。其中該第一接觸部1211b的最低點與該第二接觸部1214的最低點均突伸入該插槽1111內（如圖4所示），從而可以按照先後次序地與***該插槽1111內的該電路板2建立接觸。The first contact portion 1211b of the signal terminal 121b and the first contact portion 1211a and the second contact portion 1214 of the ground terminal 121a are all U-shaped, and the opening directions of the U-shaped are all facing the upper side (or facing away from the slot). 1111). In the free state without additional pressure as shown in FIG. 10, the lowest point of the first contact portion 1211b of the signal terminal 121b is preferably slightly lower than the lowest point of the first contact portion 1211a of the ground terminal 121a, and the lowest point of the first contact portion 1211a of the ground terminal 121a is preferably The lowest point of the second contact portion 1214 is located at a slightly higher horizontal position than the lowest point of the first contact portion 1211a. The lowest point of the first contact portion 1211b and the lowest point of the second contact portion 1214 both protrude into the slot 1111 (as shown in FIG. 4 ), so that they can be inserted into the slot 1111 in sequence. of this circuit board 2 to establish contact.

再參閱圖11，從垂直於橫向X的豎向(或是說垂直於紙面的方向)上看，該信號端子121b只具有第一接觸部1211b而不具有類似的第二接觸部，該接地端子121a的第二接觸部1214沿著橫向X朝向相鄰的該信號端子121b偏移。該第二接觸部1214相對於該接地端子121a的第一接觸部1211a在沿著橫向X上具有加寬的寬度。其中該第二接觸部1214背離相鄰的該信號端子121b的一側是與該第一接觸部1211a齊平的，而該第二接觸部1214的另一側則超出該第一接觸部1211a朝向該信號端子121b偏移一段加寬的寬度。Referring to FIG. 11 again, when viewed from the vertical direction perpendicular to the transverse direction X (or the direction perpendicular to the paper surface), the signal terminal 121b only has a first contact portion 1211b without a similar second contact portion. The ground terminal The second contact portion 1214 of the 121a is offset along the lateral direction X toward the adjacent signal terminal 121b. The second contact portion 1214 has a wider width along the lateral direction X with respect to the first contact portion 1211a of the ground terminal 121a. The side of the second contact portion 1214 facing away from the adjacent signal terminal 121b is flush with the first contact portion 1211a, and the other side of the second contact portion 1214 extends beyond the first contact portion 1211a toward the The signal terminal 121b is offset by a widened width.

從垂直於橫向X的豎向上看，即從圖11所示意的視圖方向（或俯視方向）來看，該接地端子121a的第二接觸部1214與相鄰的該信號端子121b的第一接觸部1211b在前後方向上的投影有一小部分重疊。沿著該第二接觸部1214的朝向該信號端子121b的上邊緣前後延伸的一直線L將穿過該信號端子121b的第一接觸部1211b，即存在部分重疊。Viewed from the vertical direction perpendicular to the lateral direction X, that is, viewed from the view direction (or plan view direction) shown in FIG. 11 , the second contact portion 1214 of the ground terminal 121 a and the adjacent first contact portion of the signal terminal 121 b The projection of 1211b in the front-to-back direction has a small overlap. A straight line L extending back and forth along the upper edge of the second contact portion 1214 toward the signal terminal 121b will pass through the first contact portion 1211b of the signal terminal 121b, ie, there is a partial overlap.

在本較佳實施例中，將該接地端子121a的第一接觸部1211a的寬度標記為W1，該第二接觸部1214的寬度標記為W2，該信號端子121b的第一接觸部1211b的寬度標記為W3，該接地端子121a的第一接觸部1211a與相鄰的該信號端子121b的第一接觸部1211b之間的間隔為d，則：該第二接觸部1214的寬度W2大於該接地端子121a的第一接觸部1211a的寬度W1與該間隔d之和，即W2＞W1+d。In this preferred embodiment, the width of the first contact portion 1211a of the ground terminal 121a is marked as W1, the width of the second contact portion 1214 is marked as W2, and the width of the first contact portion 1211b of the signal terminal 121b is marked as is W3, and the interval between the first contact portion 1211a of the ground terminal 121a and the adjacent first contact portion 1211b of the signal terminal 121b is d, then: the width W2 of the second contact portion 1214 is greater than that of the ground terminal 121a The sum of the width W1 of the first contact portion 1211a and the interval d is W2>W1+d.

在一些未示出的實施例中，該第二接觸部1214的寬度還可以設置為使該第二接觸部1214與相鄰的該信號端子121b的第一接觸部1211b在前後方向上的投影全部重疊，在這種情形下，該第二接觸部1214的寬度用數學式來表示，則：W2≥W1+d+W3。In some unshown embodiments, the width of the second contact portion 1214 may also be set so that the projection of the second contact portion 1214 and the adjacent first contact portion 1211b of the signal terminal 121b in the front-rear direction is completely Overlapping, in this case, the width of the second contact portion 1214 is represented by a mathematical formula, then: W2≥W1+d+W3.

另外，在其他一些未示出的實施例中，該第二接觸部1214的背離該信號端子121b的一側也可以不與該接地端子121a的第一接觸部1211a齊平，而是同樣朝向該信號端子121b有所偏移，在這種情況下，理論上該第二接觸部1214的寬度W2大於間隔d即可。也就是說，該第二接觸部1214在前後方向上的投影覆蓋該間隔d，並較佳與該信號端子121b的第一接觸部1211b有部分重疊，即W2稍微大於d即可。In addition, in some other unshown embodiments, the side of the second contact portion 1214 away from the signal terminal 121b may not be flush with the first contact portion 1211a of the ground terminal 121a, but also faces the same. The signal terminal 121b is offset. In this case, theoretically, the width W2 of the second contact portion 1214 may be larger than the interval d. That is, the projection of the second contact portion 1214 in the front-rear direction covers the interval d, and preferably partially overlaps with the first contact portion 1211b of the signal terminal 121b, that is, W2 is slightly larger than d.

在本較佳實施例中，由於兩個信號端子121b是位於兩個接地端子121a之間的，相應地，兩個接地端子121a的第二接觸部1214是相互靠近地加寬的，即兩個接地端子121a的第二接觸部1214是分別地朝向其對應相鄰的一信號端子121b偏移的，從而兩個接地端子121a的兩個第二接觸部1214之間的距離小於兩個第一接觸部1211a之間的距離。In this preferred embodiment, since the two signal terminals 121b are located between the two ground terminals 121a, correspondingly, the second contact portions 1214 of the two ground terminals 121a are widened close to each other, that is, two The second contact portions 1214 of the ground terminals 121a are respectively offset toward its corresponding adjacent one of the signal terminals 121b, so that the distance between the two second contact portions 1214 of the two ground terminals 121a is smaller than the two first contacts distance between parts 1211a.

結合圖4，當該接地端子121a固定於該絕緣座體11中時，該第二接觸部1214的末端伸入於該凹槽113中，並可以在該凹槽113中上下活動。本較佳實施例中，該凹槽113的數量為兩個，並分別對應收容一個接地端子121a的第二接觸部1214。Referring to FIG. 4 , when the ground terminal 121 a is fixed in the insulating base 11 , the end of the second contact portion 1214 extends into the groove 113 and can move up and down in the groove 113 . In this preferred embodiment, the number of the grooves 113 is two, and the second contact portions 1214 of one grounding terminal 121a are correspondingly accommodated respectively.

根據上述的介紹，本較佳實施例的該電連接器1的裝配過程大致為：注塑成型該絕緣座體11，將多個第一導電端子121組成的第一組導電端子12與該固定座14通過***成型工藝結合為一整體，將該第一組導電端子12與該固定座14構成的整體從該絕緣座體11的後端112向前裝入該絕緣座體11內，將多個第二導電端子131組成的第二組導電端子13從該絕緣座體11的前端111向後裝入該絕緣座體11內。According to the above description, the assembly process of the electrical connector 1 in this preferred embodiment is roughly as follows: injection molding the insulating base 11 , and connecting the first set of conductive terminals 12 composed of a plurality of first conductive terminals 121 to the fixing base 14 is combined into a whole through an insert molding process, and the whole formed by the first group of conductive terminals 12 and the fixing seat 14 is inserted into the insulating seat body 11 from the rear end 112 of the insulating seat body 11 forward, and a plurality of The second group of conductive terminals 13 composed of the second conductive terminals 131 is installed into the insulating base 11 from the front end 111 of the insulating base 11 backwards.

本較佳實施例的該電連接器1用於供一電路板2（如圖12所示）插接其中，通過在該接地端子121a中增加的向前延伸並朝向相鄰的信號端子121b偏移的該第二接觸部1214，可以向該電路板2提供預放電功能以釋放該電路板2的信號電路中的靜電及殘餘電荷，防範對電子元件造成損害。具體將通過下文中具有該電連接器1的電連接器組合100的實施例進行更為詳細的說明。The electrical connector 1 of this preferred embodiment is used for a circuit board 2 (as shown in FIG. 12 ) to be plugged into it, and the ground terminal 121 a extends forward and is biased toward the adjacent signal terminal 121 b by adding an extension to the ground terminal 121 a The moved second contact portion 1214 can provide the circuit board 2 with a pre-discharge function to release static electricity and residual charges in the signal circuit of the circuit board 2 to prevent damage to electronic components. Specifically, a more detailed description will be given below through the embodiment of the electrical connector assembly 100 having the electrical connector 1 .

接著參閱圖12，其示意了本較佳實施例的電連接器組合100。具體地，該電連接器組合100包括上述的該電連接器1以及可以與該電連接器1對應插接的電路板2。Next, referring to FIG. 12 , it illustrates the electrical connector assembly 100 of this preferred embodiment. Specifically, the electrical connector assembly 100 includes the above-mentioned electrical connector 1 and a circuit board 2 that can be plugged with the electrical connector 1 correspondingly.

該電路板2包括一基板21和設置於該基板21的上下表面的沿橫向X排列的多個金手指22。其中圖12所示出的位於該基板21的上表面的這些金手指22用於與該電連接器1的第一組導電端子12形成電連接，這些金手指22的數量及功能分別與該第一組導電端子12的第一導電端子121相適配。可以理解的是，在該基板21的下表面設置的另一些金手指22用於與該電連接器1的第二組導電端子13形成電連接。The circuit board 2 includes a substrate 21 and a plurality of gold fingers 22 arranged on the upper and lower surfaces of the substrate 21 and arranged along the lateral direction X. The gold fingers 22 located on the upper surface of the substrate 21 shown in FIG. 12 are used to form electrical connections with the first group of conductive terminals 12 of the electrical connector 1 , and the number and function of the gold fingers 22 are respectively related to the first group of conductive terminals 12 . The first conductive terminals 121 of a group of conductive terminals 12 are adapted to each other. It can be understood that other gold fingers 22 disposed on the lower surface of the substrate 21 are used to form electrical connections with the second group of conductive terminals 13 of the electrical connector 1 .

如圖13所示，相應於該第一組導電端子12的兩個接地端子121a和兩個信號端子121b，這些金手指22中位於一側的四個金手指22對應地為設置為用於傳輸信號的兩個信號金手指22b及用於實現接地功能的兩個接地金手指22a。兩個信號金手指22b位於兩個接地金手指22a之間，該兩個接地金手指22a相對於該兩個信號金手指22b向前突伸出。該接地金手指22a的前端基本接近於該基板21的前端面，而該信號金手指22b與該基板21的前端面則具有距離h。As shown in FIG. 13 , corresponding to the two ground terminals 121 a and the two signal terminals 121 b of the first group of conductive terminals 12 , the four gold fingers 22 on one side of the gold fingers 22 are correspondingly configured for transmission The two signal gold fingers 22b for the signal and the two ground gold fingers 22a for realizing the grounding function. The two signal gold fingers 22b are located between the two ground gold fingers 22a, and the two ground gold fingers 22a protrude forward relative to the two signal gold fingers 22b. The front end of the ground gold finger 22 a is substantially close to the front end surface of the substrate 21 , and the signal gold finger 22 b has a distance h from the front end surface of the substrate 21 .

參閱圖14至圖17，當該電連接器1與該電路板2初始對接時，該電路板2的前端插接到該電連接器1的插槽1111中，該接地端子121a的第二接觸部1214將首先接觸該接地金手指22a。該電路板2繼續伸入該插槽1111的深度達到距離h時，該第二接觸部1214在保持與該接地金手指22a接觸的同時，還將一併接觸到與該接地金手指22a相鄰的信號金手指22b，此時的狀態具體可參閱圖16。如圖17所示，此時該電路板2還未與該電連接器1的信號端子121b接觸，該信號端子121b與該電路板2尚未建立電連接。14 to 17, when the electrical connector 1 is initially docked with the circuit board 2, the front end of the circuit board 2 is inserted into the slot 1111 of the electrical connector 1, and the second contact of the ground terminal 121a The portion 1214 will first contact the ground gold finger 22a. When the depth of the circuit board 2 extending into the slot 1111 reaches the distance h, the second contact portion 1214 will keep in contact with the ground gold finger 22a, and will also be in contact with the ground gold finger 22a. The state of the signal gold finger 22b at this time can be found in FIG. 16 for details. As shown in FIG. 17 , at this time, the circuit board 2 has not been in contact with the signal terminal 121 b of the electrical connector 1 , and the signal terminal 121 b and the circuit board 2 have not yet been electrically connected.

在該初始對接狀態下，該第二接觸部1214將建立該信號金手指22b與該接地金手指22a之間的連接通路，為該信號金手指22b提供預放電功能，該電路板2的信號電路中的靜電及殘餘電荷將通過該信號金手指22b傳導至該接地端子121a和該接地金手指22a並釋放出去。In the initial docking state, the second contact portion 1214 will establish a connection path between the signal gold finger 22b and the ground gold finger 22a, and provide a pre-discharge function for the signal gold finger 22b. The signal circuit of the circuit board 2 The static electricity and the residual charge in the ions will be conducted to the ground terminal 121a and the ground gold finger 22a through the signal gold finger 22b and released.

接著參閱圖18和圖19，當該電路板2繼續***該電連接器1的插槽1111內至對接完成時，改為由該接地端子121a的第一接觸部1211a與該電路板2的接地金手指22a建立接觸，及與該接地端子121a相鄰的信號端子121b對應與該鄰近的信號金手指22b建立接觸以傳遞電信號。此時，該接地端子121a的第二接觸部1214被朝上抬升遠離該電路板2，與該電路板2具有一間隔，從而該接地端子121a的第二接觸部1214與該電路板22的接地金手指22a及鄰近的信號金手指22b均脫離接觸，此時該電連接器1的絕緣座體11上的凹槽113將為該第二接觸部1214提供向上抬升的空間。18 and FIG. 19, when the circuit board 2 continues to be inserted into the slot 1111 of the electrical connector 1 until the mating is completed, the first contact portion 1211a of the ground terminal 121a and the circuit board 2 are grounded instead. The gold finger 22a establishes contact, and the signal terminal 121b adjacent to the ground terminal 121a establishes a corresponding contact with the adjacent signal gold finger 22b to transmit electrical signals. At this time, the second contact portion 1214 of the grounding terminal 121a is lifted up and away from the circuit board 2 and has a space from the circuit board 2 , so that the second contacting portion 1214 of the grounding terminal 121a is grounded to the circuit board 22 . The gold finger 22a and the adjacent signal gold finger 22b are out of contact, and the groove 113 on the insulating base 11 of the electrical connector 1 will provide a space for the second contact portion 1214 to rise upward.

基於上述描述可知，本較佳實施例的電連接器組合100，在該電連接器1與該電路板2插接的過程中，通過該接地端子121a中向前延伸出的加寬的該第二接觸部1214，可以建立供該電路板2進行靜電及殘餘電荷釋放的通路，從而可以有效防範靜電及殘餘電荷對電子元件的損害。Based on the above description, in the electrical connector assembly 100 of this preferred embodiment, during the process of plugging the electrical connector 1 with the circuit board 2 , through the widened first ground terminal 121 a extending forward The second contact portion 1214 can establish a path for the circuit board 2 to discharge static electricity and residual charges, thereby effectively preventing damage to electronic components caused by static electricity and residual charges.

That is, the four leftmost first conductive terminals of the first group of conductive terminals 42 are respectively two ground terminals 421a and two signal terminals 421b located between the two ground terminals 421a, and the two signal terminals 421b on the left A pair of differential signal terminals is formed; and the four rightmost first conductive terminals of the first group of conductive terminals 42 are also two ground terminals 421a and two signal terminals 421b located between the two ground terminals 421a respectively. , the two signal terminals 421b on the right side also constitute another pair of differential signal terminals.

每一個接地端子421a均具有朝向各自相鄰的一信號端子421b偏移的該第二接觸部4214，從而通過該加寬的第二接觸部4214提供靜電及殘餘電荷釋放功能。Each of the ground terminals 421a has the second contact portion 4214 offset toward the respective adjacent one of the signal terminals 421b, so as to provide static electricity and residual charge discharge functions through the widened second contact portion 4214 .

本實施例中，該絕緣座體41的頂部設有沿導電端子排列的橫向X具有較大寬度的一凹槽413，該凹槽413可以同時收容向上抬升的該四個接地端子421a。In this embodiment, the top of the insulating base 41 is provided with a groove 413 having a larger width along the lateral direction X of the conductive terminals.
