New description: [New technical field] The present invention relates to a terminal and an electrical connector, and more particularly to a terminal suitable for a planar gate array (LGA) electrical connector and an electric device having the same Connector. [Prior Art] • Referring to FIG. 1 and FIG. 2, a planar grid array electrical connector 9 for electrically connecting a chip module (not shown) and a circuit board (not shown) is included. The body 91 and the plurality of terminals 92 are provided. The insulating housing 91 has a plurality of terminal slots 911 arranged in an array for accommodating the terminals 92.

Department 924. Since the wafer module is electrically connected to the electrical connector 9 in a crimping manner, in order to enable stable electrical connection between the wafer module and the electrical connector 9, the elastic arm 923 of the terminal 92 must have a sufficient length to provide Appropriate restoring force, when the contact portion 924 contacts the wafer module and withstands the pressure of the wafer module, the restoring force provided by the elastic arm 923 can cause the contact portion 924 to generate a positive pressure against the wafer module, and the wafer mold The set can be in stable contact with the terminal 92. However, as wafer modules are increasingly becoming smaller and higher in transmission speed, the density of the terminals 92 of the electrical connector 9 is becoming higher and higher, that is, the distance between the terminals 92 is getting smaller and smaller, causing the terminal 92 to be subjected to the wafer mold. When the pressure of the group is pressed down, the front end of the contact portion 924 easily touches the adjacent terminal 92 to cause a short circuit. For example, as shown in Fig. 2, the elastic arms 923 of the respective terminals 92 are obliquely arranged 5 • M345382 (4), and the body milk which is easily touched by the diagonal 92 of the terminal groove 911 when pressed down.

彈性臂23係由第二本體部212往上彎折延伸出各端子 槽11，彈性臂23彎曲的曲度可視需要調整，如圖6及圖7 所示，分別為不同曲度的彈性臂23。再參閱圖4與圖9, 接觸部24由彈性臂23延伸並於前端反折，使接觸部24具 有一主體段24!及-反折段242。反折段242内侧與主體段 241具有一間隙243，且該間隙243小於端子2板體之厚度 t，較佳地，該間隙243也可趨近於零，亦即，反折段242 内側可與主體段241相接觸。 配&參閱圖8，在本貫施例中，第一本體部211與第二 本體部212之夾角介於90〜180度之間，所以各端子2設於 端子槽11時，其彈性臂23及接觸部24相對於設有第一本 體部211的端子槽U壁面呈一傾斜角度，而使每一端子2 的彈性臂23及接觸部24朝一傾斜方向平行排列。 如圖9所示，本實施例之端子2與習知的端子92相較 ，在相同的接觸點下，本實施例的端子2長度可縮減距離d ，並提高高度h，故可使接觸部24在受壓行程不易碰觸相 鄰端子以避免短路。 3及 參閱圖10〜圖13,本新型電連接器之第二較佳實施例 ’與前述第一較佳實施例大致相同，包含一絕緣殼體 8 M345382 多數根具有導電性的端子4。絕緣殼體3具有多數個呈陣列 排列的端子槽31。每一端子4分別設於各端子槽31中，包 括一本體41、一電氣連接部42、一彈性臂43及一接觸部 44。本體41具有侧緣相鄰的一第一本體部411及一第二本 體部412。第二較佳實施例與第一較佳實施例差異之處在於 ，端子4本體41之第一本體部411及第二本體部412之夾 角概呈·直角，所以各端子4設於端子槽31時，其彈性臂43 及接觸部44相對於設有第一本體部411的端子槽31壁面概 呈平打，而使同列的每一端子4的彈性臂43及接觸部44 朝一直線方向排列。如前述第一較佳實施例，同樣地，本 實施例之端子4與習知的端子93相較（參閱圖9)，在相同 的接觸點下，本實施例的端子4長度亦可縮減距離^，並提 尚南度h，故可使接觸部44在受壓行程不易碰觸相鄰端子 以避免短路。 參閱圖14,本新型電連接器之第兰較佳實施例，與第 -實施例Λ致相同，.准，第三較佳實施例的端+ $之接觸 部51與第一較佳實施例之端子2的接觸部24朝相反方向 反折，而使反折段511位於主體段512上方，亦可具有不易 碰觸相鄰端子以避免短路之功效。 綜合上述，本新型電連接器之端子，藉由接觸部之反 折段較貼近主體段，與習知的端子相較，可在相同接觸點 下，縮短接觸部的長度並提高接觸部的高度，使得接觸部 在受壓行程中不易接觸相鄰的端子，以避免造成短路。 准以上所述者，僅為本新型之較佳實施例而已，當不 9 ▲ M345382 =以此限定本新型實施之範圍，即大凡依本新型中請專利 把圍及新型說明内容所作之簡單的等效變化與修飾，皆仍 屬本新型專利涵蓋之範圍内。 【圖式簡單說明】 圖1是-局部立體分解圖，說明一習知的電連接器， 圖中所示為該電連接器之一部份； 圖2是一圖1的俯視圖，說明該習知的電連接器； &圖3是一截面示意圖，說明另一習知的電連：器之端 子悲樣，圖中所示為該電連接器之一部份； 圖4是-局部立體分解圖，說明本新型電連接器及端 子的第-較佳實施例，圖中所示為該電連接器之—部份； 圖5是一圖4的另一角度視圖； 圖6是一圖4的截面示意圖； 山圖7是一類似圖6的視圖，說明該第一較佳實施例之 端子的彈性臂在不同的彎曲曲度； 圖8是一圖4的俯視圖； 圖9是一立冑圖，說明該第—較佳實施例的端子與習 知的端子之接觸部的比較； •广0圖13疋說明本新型電連接器及端子的第二較佳 4例的不同角度視圖’圖中所示為該電連接器之一部份 ，及 圖W是說明本新型電連接器及端子的第三較佳實施例 、立體圖’圖中所示為該電連接器之一部份。 10 .M345382The elastic arm 23 is bent upwardly from the second body portion 212 to extend out the terminal slots 11. The curvature of the elastic arms 23 can be adjusted as needed. As shown in FIG. 6 and FIG. 7, the elastic arms 23 of different curvatures are respectively shown. . Referring again to Figures 4 and 9, the contact portion 24 extends from the resilient arm 23 and is folded back at the front end such that the contact portion 24 has a body portion 24! and a reflexed portion 242. The inner side of the folding portion 242 has a gap 243 with the body portion 241, and the gap 243 is smaller than the thickness t of the plate body of the terminal 2. Preferably, the gap 243 can also approach zero, that is, the inner side of the folding portion 242 can be It is in contact with the body segment 241. Referring to FIG. 8 , in the present embodiment, the angle between the first body portion 211 and the second body portion 212 is between 90 and 180 degrees, so that when the terminals 2 are disposed in the terminal slot 11 , the elastic arms thereof 23 and the contact portion 24 are inclined at an angle with respect to the wall surface of the terminal groove U provided with the first body portion 211, so that the elastic arm 23 and the contact portion 24 of each terminal 2 are arranged in parallel in an oblique direction. As shown in FIG. 9, the terminal 2 of this embodiment is compared with the conventional terminal 92. Under the same contact point, the length of the terminal 2 of the embodiment can be reduced by the distance d and the height h is increased, so that the contact portion can be made. 24 It is not easy to touch adjacent terminals during the pressure stroke to avoid short circuit. 3 and Referring to Figures 10 to 13, the second preferred embodiment of the present invention is substantially identical to the first preferred embodiment described above and includes an insulative housing 8 M345382 having a plurality of electrically conductive terminals 4. The insulating housing 3 has a plurality of terminal slots 31 arranged in an array. Each of the terminals 4 is disposed in each of the terminal slots 31, and includes a body 41, an electrical connection portion 42, a resilient arm 43, and a contact portion 44. The body 41 has a first body portion 411 and a second body portion 412 adjacent to each other. The second preferred embodiment differs from the first preferred embodiment in that the angle between the first body portion 411 and the second body portion 412 of the body 4 of the terminal 4 is substantially right angle, so that each terminal 4 is disposed in the terminal slot 31. At this time, the elastic arm 43 and the contact portion 44 are substantially flush with respect to the wall surface of the terminal groove 31 provided with the first body portion 411, and the elastic arms 43 and the contact portions 44 of each terminal 4 of the same row are arranged in the line direction. As in the foregoing first preferred embodiment, similarly, the terminal 4 of the present embodiment is compared with the conventional terminal 93 (refer to FIG. 9). Under the same contact point, the length of the terminal 4 of the embodiment can also be reduced. ^, and the degree of south is h, so that the contact portion 44 can not easily touch the adjacent terminals during the pressurized stroke to avoid a short circuit. Referring to FIG. 14, a preferred embodiment of the first embodiment of the present invention is the same as that of the first embodiment. The contact portion 51 of the end + of the third preferred embodiment is compared with the first preferred embodiment. The contact portion 24 of the terminal 2 is folded in the opposite direction, and the folded portion 511 is located above the main body segment 512, and may also have the effect of not easily touching adjacent terminals to avoid short circuit. In summary, the terminal of the novel electrical connector is closer to the main body segment by the reflexed portion of the contact portion, and the length of the contact portion can be shortened and the height of the contact portion can be increased at the same contact point as compared with the conventional terminal. Therefore, the contact portion is less likely to contact adjacent terminals during the pressurized stroke to avoid a short circuit. The above-mentioned ones are only the preferred embodiments of the present invention. When 9 ▲ M345382 = this limits the scope of the implementation of the present invention, that is, the simplicity of the patent application and the new description of the present invention. Equivalent changes and modifications are still within the scope of this new patent.
