習知技術中，浮動式連接器具有固定在基板上之固定外殼、設有對接槽之可動外殼及由固定外殼和可動外殼共同保持之接觸件，所述對接槽用於收容對接連接器。由於可動外殼可依靠接觸件之彈力而相對於固定外殼自由移動，消除與對接連接器配合時所產生的錯位。是以與對接連接器可靠地配合時，不會損傷外殼或使接觸件發生塑性變形。然，習知的浮動式連接器之接觸件大多數為U型或L型的彈性端子，而U型或L型彈性端子發生形變時其穩定性能欠佳，且承受形變及形變恢復能力也一般。 In the prior art, the floating connector has a fixed outer casing fixed to the base plate, a movable outer casing provided with the abutting groove, and a contact member jointly held by the fixed outer casing and the movable outer casing, and the docking groove is for receiving the butt joint. Since the movable housing can freely move relative to the fixed housing by the elastic force of the contact member, the misalignment generated when mating with the mating connector is eliminated. When the mating connector is reliably mated, the outer casing is not damaged or the contact member is plastically deformed. However, most of the contacts of the conventional floating connector are U-shaped or L-shaped elastic terminals, and the U-shaped or L-shaped elastic terminals have poor stability when deformed, and the deformation and deformation recovery capabilities are also generally .

所以，希望設計一種新型之浮動式電連接器以改善上述問題。 Therefore, it is desirable to design a new type of floating electrical connector to improve the above problems.

請參閱第一圖所示，本實用新型揭示了一種浮動式電連接器100，該浮動式電連接器100包括絕緣本體及導電端子3，絕緣本體包括固定本體1及位於固定本體1內之浮動本體2，導電端子3則由固定本體1和浮動本體2雙方共同保持。 Referring to the first figure, the present invention discloses a floating electrical connector 100. The floating electrical connector 100 includes an insulative housing and a conductive terminal 3. The insulative housing includes a fixed body 1 and a floating body located in the fixed body 1. The body 2 and the conductive terminal 3 are jointly held by both the fixed body 1 and the floating body 2.

The fixing body 1 includes two side walls 11 extending in the longitudinal direction and two end walls 12 connecting the two side walls 11. The two side walls 11 and the two end walls 12 are enclosed around the frame portion and penetrate the frame portion in the butting direction. Internal space 10. A first terminal channel 111 for receiving the conductive terminal 3 is disposed outside the two side walls 11 of the fixed body 1. The floating body 2 has a base portion 20 located above the frame portion of the fixed body 1 and a concave wall 21 protruding downward from the center of the base portion 20 and extending into the inner space 10. The inner wall surface of the concave wall 21 is formed parallel to the mating direction. Docking groove 210. The docking slot 210 is configured to receive the abutting portion of the mating connector when the floating electrical connector 100 is mated with the mating connector (not shown), and is longitudinally adjacent to the mating slot 210 of the floating body 2 The concave wall 21 in the direction is provided with a second terminal channel 211 for receiving the conductive terminal 3. A terminal movable space 13 is also formed between the side wall 11 of the fixed body 1 and the concave wall 21 of the floating body 2.

所述導電端子3包括沿對接方向延伸且固定於浮動本體2之接觸部31、固定於固定本體1之固持部32及連接接觸部31與固持部32之S型可撓動部33。導電端子之接觸部31通過倒刺干涉固持於浮動本體2的對接槽210兩側的第二端子槽道211，固持部32亦通過倒刺干涉固持於固定本體1的兩側壁11外側的第一端子槽道111且固持部32向外延伸出固定本體1形成用於焊接於電路板(未圖示)之焊接部34。 The conductive terminal 3 includes a contact portion 31 extending in the mating direction and fixed to the floating body 2 , a holding portion 32 fixed to the fixed body 1 , and an S-shaped flexible portion 33 connecting the contact portion 31 and the holding portion 32 . The contact portion 31 of the conductive terminal is held by the second terminal channel 211 on both sides of the mating groove 210 of the floating body 2 by barb interference, and the holding portion 32 is also held by the barb interference on the outer side of the two side walls 11 of the fixed body 1 The terminal channel 111 and the holding portion 32 extend outwardly to form the fixing body 1 Soldering to a soldering portion 34 of a circuit board (not shown).

結合第五圖可知，該可撓動部33位於所述端子活動空間13內且包括分別與接觸部31和固持部32相連接之第一彈性圓弧部331與第二彈性圓弧部332，以及與第一、第二彈性圓弧部相連接之連接部333。第一彈性圓弧部331及第二彈性圓弧部332分別與浮動本體2之凹壁21及固定本體1的側壁11間距一定距離，使得可撓動部33可在所述端子活動空間13內有一定的位移空間。在對接方向上，第一彈性圓弧部331的末端較浮動本體2的凹壁21的末端遠離浮動本體2的基部20。同時浮動本體2在對應第一彈性圓弧部331外側處為開放式形成讓位空間15，減小浮動本體於外側的側壁的使用，從而降低了該浮動式電連接器100的整體高度。 As can be seen from the fifth figure, the flexible portion 33 is located in the terminal movable space 13 and includes a first elastic arc portion 331 and a second elastic arc portion 332 respectively connected to the contact portion 31 and the holding portion 32. And a connecting portion 333 connected to the first and second elastic arc portions. The first elastic arc portion 331 and the second elastic arc portion 332 are spaced apart from the concave wall 21 of the floating body 2 and the side wall 11 of the fixed body 1 respectively, so that the flexible portion 33 can be in the terminal movable space 13 There is a certain amount of displacement space. In the butting direction, the end of the first elastic circular arc portion 331 is farther from the base portion 20 of the floating body 2 than the end of the concave wall 21 of the floating body 2. At the same time, the floating body 2 is openly formed at the outer side of the corresponding first elastic arc portion 331 to reduce the use of the side wall of the floating body on the outer side, thereby reducing the overall height of the floating electrical connector 100.

該第一彈性圓弧部331及第二彈性圓弧部332的一端分別與接觸部31和固持部32相切，第一彈性圓弧部331及第二彈性圓弧部332的另一端分別與連接部333相切，且第一彈性圓弧部331與第二彈性圓弧部332的直徑之和大於接觸部31與固持部32的間距，即第一彈性圓弧部331及第二彈性圓弧部332在垂直於對接方向的平面上的投影部分重疊，使得S型可撓動部33的連接部333與對接方向之間形成一定角度，使得該可撓動部13發生形變時具有“內斂”的優點，即其形變僅發生在絕緣本體的端子活動空間13的較小範圍內。 One ends of the first elastic arc portion 331 and the second elastic arc portion 332 are respectively tangent to the contact portion 31 and the holding portion 32, and the other ends of the first elastic circular arc portion 331 and the second elastic circular arc portion 332 are respectively The connecting portion 333 is tangent, and the sum of the diameters of the first elastic arc portion 331 and the second elastic arc portion 332 is larger than the distance between the contact portion 31 and the retaining portion 32, that is, the first elastic arc portion 331 and the second elastic circle. The projection portion of the arc portion 332 on the plane perpendicular to the mating direction overlaps such that the connecting portion 333 of the S-shaped flexible portion 33 forms an angle with the mating direction, so that the flexible portion 13 is "introverted" when deformed. The advantage of the deformation is that it only occurs within a small range of the terminal active space 13 of the insulative housing.

所述浮動式電連接器100還設有扣持於固定本體1兩端壁12之金屬固定件4。該金屬固定件4包括主體部41、自主體部41兩端彎折延伸並扣持於固定本體1端壁12之扣持部42及自主體部41兩端向下彎折延伸之基板固定部43。該金屬固定件4之扣持部42固定安裝於固定本體1之兩端壁12的扣持槽14內。 The floating electrical connector 100 is further provided with a metal fixing member 4 that is fastened to the two end walls 12 of the fixed body 1. The metal fixing member 4 includes a main body portion 41, and a fastening portion 42 that is bent and extended from both ends of the main body portion 41 and is fastened to the end wall 12 of the fixing body 1 and the main body The substrate fixing portion 43 is bent and extended at both ends of the portion 41. The fastening portion 42 of the metal fixing member 4 is fixedly mounted in the fastening groove 14 of the two end walls 12 of the fixing body 1.

本實用新型相對於現有技術的改進特徵在於第一彈性圓弧部331及第二彈性圓弧部332在垂直於對接方向的平面上的投影部分重疊，使得S型可撓動部33之連接部333與對接方向之間具有負角度特徵，對於控制形變的平穩度有較佳效果，且S型端子結構在承受形變及形變恢復時性能亦較佳。 An improvement of the present invention over the prior art is that the projection portions of the first elastic arc portion 331 and the second elastic arc portion 332 on a plane perpendicular to the mating direction overlap such that the connection portion of the S-shaped flexible portion 33 The negative angle between the 333 and the mating direction has a better effect on controlling the smoothness of the deformation, and the S-type terminal structure also performs better when subjected to deformation and deformation recovery.
