以下結合本說明書的附圖，對本新型的較佳實施例予以進一步地詳盡闡述。 The preferred embodiments of the present invention are further elaborated below in conjunction with the drawings of the specification.
參見圖1至圖6，本新型提出一種彈片端子，其是由一金屬板材一體衝壓彎折而成。該彈片端子包括一底板1、由該底板1的後端先向上再向前彎折延伸出的一彈性臂2、由該彈性臂2的前端進一步向上彎折延伸出的一接觸部3、由該底板1的前端向上彎折延伸出的一前保護板4、分別由該前保護板4的兩側緣向後彎折延伸出的兩側保護板5以及由該兩側保護板5向內突伸出的兩個按壓突片6。 Referring to FIG. 1 to FIG. 6, the present invention proposes a shrapnel terminal which is integrally stamped and bent from a metal plate. The elastic piece terminal includes a bottom plate 1, a resilient arm 2 bent upwardly and forwardly from the rear end of the bottom plate 1, and a contact portion 3 which is further bent upwardly from the front end of the elastic arm 2, a front protective plate 4 bent upwardly from the front end of the bottom plate 1 and two side protective plates 5 bent outwardly from the side edges of the front protective plate 4 and inwardly protruding from the two side protective plates 5 Two pressing tabs 6 projecting out.
該底板1具有位於前方的較窄的一頸部11和位於後方的較寬的一焊固部12。該底板1在焊固部12的中部設有一抓錫孔13。在本實施例中，該抓錫孔13呈矩形狀。該底板1並在該抓錫孔13兩側設有多個抓錫凹口14。該焊固部12可以採用表面焊接的方式焊接到一電路板(圖未示)上。這種抓錫孔13與抓錫凹口14，可以很好地增強焊錫與該底板1之間的結合力。 The bottom plate 1 has a narrower neck portion 11 at the front and a wider weld portion 12 at the rear. The bottom plate 1 is provided with a tin-trapping hole 13 in the middle of the welded portion 12. In the embodiment, the tin-trapping hole 13 has a rectangular shape. The bottom plate 1 is provided with a plurality of soldering recesses 14 on both sides of the soldering hole 13 . The soldering portion 12 can be soldered to a circuit board (not shown) by surface soldering. The tin-trapping hole 13 and the tin-trapping recess 14 can well enhance the bonding force between the solder and the bottom plate 1.
該彈性臂2包括由該底板1的後端向上豎直彎折延伸出的一豎直延伸段21及由該豎直延伸段21的頂端向前水平彎折延伸出的一水平延伸段22。該彈性臂2與該底板1圍合出一個橫倒的U形 的彈性框架結構。 The elastic arm 2 includes a vertical extension 21 extending vertically upward from the rear end of the bottom plate 1 and a horizontal extension 22 extending horizontally from the top end of the vertical extension 21. The elastic arm 2 and the bottom plate 1 enclose a horizontal U shape Flexible frame structure.
該接觸部3呈倒U形狀，其是由該彈性臂2的前端先向後向上地傾斜彎折延伸，到達最高點後再向後向下傾斜彎折延伸而成的。這種向後拱彎的接觸部3結構，可以在保持相同彈性力臂長度的同時，縮減彈片端子的總體長度，從而有利於彈片端子的微型化。該接觸部3的頂面向上凸設形成有一凸肋35，有利於提高其結構強度。 The contact portion 3 has an inverted U shape, and the front end of the elastic arm 2 is bent and extended obliquely backward and upward, and reaches the highest point, and then is bent downward and downwardly and bent and extended. The structure of the rearwardly arched contact portion 3 can reduce the overall length of the shrapnel terminal while maintaining the same elastic arm length, thereby facilitating miniaturization of the shrapnel terminal. A rib 35 is formed on the top surface of the contact portion 3 so as to be convex, which is advantageous for improving the structural strength.
該前保護板4的頂面高於該彈性臂2的頂面25，並且低於該接觸部3的頂面。這兩個側保護板5的頂面55高於該彈性臂2的頂面25，並且低於該接觸部3的頂面，從而可以阻止該彈片端子被過度下壓發生不適當的變形。在本實施例中，該前保護板4的頂面與這兩個側保護板5的頂面55平齊。而在其他未示出的實施例中，該前保護板4的頂面與這兩個側保護板5的頂面也可以不平齊，例如：該前保護板4的頂面高於這兩個側保護板5的頂面。 The top surface of the front protective plate 4 is higher than the top surface 25 of the resilient arm 2 and lower than the top surface of the contact portion 3. The top surface 55 of the two side protection plates 5 is higher than the top surface 25 of the elastic arm 2 and lower than the top surface of the contact portion 3, so that the shrapnel terminal can be prevented from being improperly deformed by excessive depression. In the present embodiment, the top surface of the front protective plate 4 is flush with the top surface 55 of the two side protective plates 5. In other embodiments, the top surface of the front protection plate 4 and the top surfaces of the two side protection plates 5 may also be out of alignment, for example, the top surface of the front protection plate 4 is higher than the two. The top surface of the side protection plate 5.
這兩個側保護板5的底面位於該底板1的頸部11的兩側，這兩個側保護板5的外側緣不超出於該底板1的焊固部12的兩側緣，從而可以節省整個彈片端子在該電路板上的安裝面積，達到微型化的效果。 The bottom surfaces of the two side protection plates 5 are located on both sides of the neck portion 11 of the bottom plate 1. The outer edges of the two side protection plates 5 do not exceed the two side edges of the soldering portion 12 of the bottom plate 1, thereby saving The mounting area of the entire shrapnel terminal on the circuit board is miniaturized.
參見圖3，這兩個側保護板5的底面56稍稍高於該底板1的底面16，並且低於該底板1的頂面15，從而既可以不影響到底板 1的焊接，又可以在受壓時抵壓在電路板的上表面從而提供支撐。另外，在該前保護板4與側保護板5的連接處設置有多個鏤空部8，可以便於進行彎折。 Referring to FIG. 3, the bottom surface 56 of the two side protection plates 5 is slightly higher than the bottom surface 16 of the bottom plate 1, and lower than the top surface 15 of the bottom plate 1, so that the bottom plate can be neither affected The welding of 1 can again be pressed against the upper surface of the board to provide support when pressed. Further, a plurality of hollow portions 8 are provided at the joint of the front protective plate 4 and the side protective plate 5, which facilitates bending.
該按壓突片6是從對應的側保護板5的中部向內撕破形成的，並在撕破的位置處對應形成一開口。在本實施例中，該按壓突片6是從撕破的開口的上緣向下向內傾斜延伸而成的。這兩個側保護板5各向內撕破形成有一按壓突片6。這兩個按壓突片6的末端抵壓在該彈性臂2的頂面25，並位於該接觸部3的下方位置，該兩按壓突片6能夠給該彈性臂2施加向下的一預壓力，從而可以增大該接觸部3的接觸力來獲得較為穩定的電性連接。值得一提的是，在某些實施例中，也可以省略掉其中一側的按壓突片6。 The pressing tab 6 is formed by tearing inwardly from the central portion of the corresponding side protective plate 5, and an opening is formed correspondingly at the torn position. In the present embodiment, the pressing tab 6 is formed to extend obliquely downward from the upper edge of the torn opening. The two side protection plates 5 are each broken inwardly to form a pressing tab 6. The ends of the two pressing tabs 6 are pressed against the top surface 25 of the resilient arm 2 and are located below the contact portion 3, and the two pressing tabs 6 can apply a downward pre-stress to the resilient arm 2. Therefore, the contact force of the contact portion 3 can be increased to obtain a relatively stable electrical connection. It is worth mentioning that in some embodiments, the pressing tab 6 on one side may also be omitted.
本新型的彈片端子通過使前保護板4及兩個側保護板5環繞在接觸部3的周圍(具體為遮擋在接觸部3的前方和兩側)，可以防止接觸部3受到碰撞發生不適當的變形；並且，通過在至少一側保護板5上設置按壓突片6，使按壓突片6抵壓在彈性臂2的頂面25上，對該彈性臂2施加一預壓力從而可以增大接觸部3的接觸力。 The spring-loaded terminal of the present invention can prevent the contact portion 3 from being damaged by the collision by surrounding the front protective plate 4 and the two side protective plates 5 around the contact portion 3 (specifically, blocking the front and the sides of the contact portion 3). And a pressing protrusion 6 is provided on at least one of the protective plates 5 to press the pressing tab 6 against the top surface 25 of the elastic arm 2, and a pre-stress is applied to the elastic arm 2 to increase Contact force of the contact portion 3.
上述內容僅為本新型的較佳實施例，並非用於限制本新型的實施方案，本領域普通技術人員根據本新型的主要構思和精神，可以十分方便地進行相應的變通或修改，故本新型的保護範圍應以申請專利範圍所申請的保護範圍為准。 The above is only a preferred embodiment of the present invention, and is not intended to limit the embodiments of the present invention. Those skilled in the art can make corresponding modifications or modifications in a very convenient manner according to the main idea and spirit of the present invention. The scope of protection shall be subject to the scope of protection applied for in the scope of application for patents.
