該彎折部13的末端形成一擋止端部132，該擋止端部132面對於該彎折部13與該蛇形彈性部12相連接的部分。該擋止端部132將該彎折部13與該蛇形彈性部12相連接的部分擋止於其內側，從而對該蛇形彈性部12的下端起到限位作用，減輕該蛇形彈性部12的側向變形，使該蛇形彈性部12的上下伸縮更爲穩定。The end of the bending portion 13 forms a blocking end portion 132, and the blocking end portion 132 faces the part where the bending portion 13 and the serpentine elastic portion 12 are connected. The blocking end 132 blocks the portion connecting the bending portion 13 and the serpentine elastic portion 12 to the inner side thereof, thereby limiting the lower end of the serpentine elastic portion 12 and reducing the serpentine elasticity. The lateral deformation of the portion 12 makes the up and down expansion and contraction of the serpentine elastic portion 12 more stable.

再參閱圖7，該彎折部13的框體131的截面尺寸大於該包圍部14的截面尺寸。圖7所示，該框體131的寬度與該包圍部14的寬度基本相同，而該框體131的長度L1則大於該包圍部14的長度L2。Referring again to FIG. 7, the cross-sectional size of the frame 131 of the bent portion 13 is larger than the cross-sectional size of the surrounding portion 14. As shown in FIG. 7, the width of the frame 131 is substantially the same as the width of the surrounding portion 14, and the length L1 of the frame 131 is greater than the length L2 of the surrounding portion 14.

參閱圖5和圖6，該尾部15位於該導電元件1的底端，用於電連接至一電路板（圖未示出）或一線纜（圖未示出）等。本實施例中，該尾部15呈直立式片狀結構，從該彎折部13的下側緣向下延伸，可插接於一電路板對應的插孔（圖未示出）中。根據該電路板或該線纜的不同形式，該尾部15可以設計爲不同的結構形式，如直立插接式、表面貼接式等等。Referring to FIGS. 5 and 6, the tail 15 is located at the bottom end of the conductive element 1 and is used to electrically connect to a circuit board (not shown in the figure) or a cable (not shown in the figure). In this embodiment, the tail portion 15 is an upright sheet-like structure extending downward from the lower edge of the bent portion 13 and can be inserted into a corresponding socket (not shown) of a circuit board. According to different forms of the circuit board or the cable, the tail 15 can be designed in different structural forms, such as a vertical plug-in type, a surface-mount type, and so on.

參閱圖11和圖12，在一些實施例中，較佳地，該導電元件1是由一金屬片材一體衝壓彎折而成的結構，其可由片狀的料帶經過衝壓彎折加工而成。並且由於採用衝壓結構，該導電元件1的接觸部11可採用點鍍工藝增加導電性，成本較低。Referring to Figures 11 and 12, in some embodiments, preferably, the conductive element 1 is a structure formed by integral punching and bending of a metal sheet, which can be formed by punching and bending a sheet-like material strip. . In addition, due to the stamping structure, the contact portion 11 of the conductive element 1 can adopt a spot plating process to increase conductivity, and the cost is low.

參閱圖11和圖12，該導電元件1展開爲未進行彎折前的平板狀後，該彎折部13形成爲沿側向延伸的長條片狀，該蛇形彈性部12形成在平面上蛇形彎折延伸的片狀，該包圍部14的鎖固板141和環抱結構142展平爲平片狀。該彎折部13、該蛇形彈性部12、該包圍部14及該尾部15均位於同一平面上，其中，該尾部15連接在該彎折部13的下側緣，而該蛇形彈性部12和該包圍部14均連接在該彎折部13的上側緣，同時，該蛇形彈性部12與該包圍部14沿著該彎折部13的延伸長度方向呈間隔布置。11 and 12, after the conductive element 1 is unfolded into a flat plate shape before being bent, the bent portion 13 is formed into a long sheet shape extending in the lateral direction, and the serpentine elastic portion 12 is formed on a plane A serpentine bending and extending sheet shape, and the locking plate 141 and the enclosing structure 142 of the surrounding portion 14 are flattened into a flat sheet shape. The bending portion 13, the serpentine elastic portion 12, the surrounding portion 14, and the tail portion 15 are all located on the same plane, wherein the tail portion 15 is connected to the lower edge of the bending portion 13, and the serpentine elastic portion 12 and the surrounding portion 14 are both connected to the upper side edge of the bending portion 13, and at the same time, the serpentine elastic portion 12 and the surrounding portion 14 are arranged at intervals along the extension length direction of the bending portion 13.

該導電元件1在製作時，先下料衝壓出如圖11所示的狀態之後，再將該蛇形彈性部12彎折成型，接著再通過將該彎折部13進行側向彎折即可使該包圍部14與該蛇形彈性部12相對，最後將該包圍部14再折彎包圍該蛇形彈性部12。When the conductive element 1 is manufactured, the state shown in FIG. 11 is first cut out, and then the serpentine elastic portion 12 is bent to form, and then the bent portion 13 can be bent laterally. The surrounding portion 14 is opposed to the serpentine elastic portion 12, and finally the surrounding portion 14 is bent to surround the serpentine elastic portion 12 again.

該導電元件1的這種布置方式使得該導電元件1展開時的尺寸比較方正，可以減少廢料並降低料帶的寬度，有利於提高料帶的材料利用率。The arrangement of the conductive element 1 makes the size of the conductive element 1 more square when unfolded, which can reduce waste and reduce the width of the strip, which is beneficial to improve the material utilization rate of the strip.

結合上述對導電元件1的結構描述，再參閱圖1至圖4，該導電元件1安裝於該絕緣座體2時，該導電元件1的接觸部11向上突伸出該絕緣座體2的容置槽21，該尾部15向下突伸出該容置槽21以供焊接到一電路板或一導線（圖未示）。In conjunction with the above description of the structure of the conductive element 1, refer to Figures 1 to 4 again. When the conductive element 1 is mounted on the insulating base 2, the contact portion 11 of the conductive element 1 protrudes upward from the housing 2 of the insulating base. A slot 21, the tail 15 protrudes downward from the receiving slot 21 for welding to a circuit board or a wire (not shown).

該容置槽21的截面尺寸與該包圍部14的截面尺寸相適配，該容置槽21在其中一壁面處還進一步地分別向兩側突出形成有卡固槽211，該卡固槽211較佳開設在該絕緣座體2的底面，該卡固槽211的深度小於該絕緣座體2的高度。該包圍部14的鎖固板141和兩環抱結構142分別與該容置槽21的各個壁面相配合。而該包圍部14的卡固突刺143經由該卡固槽211穿入該絕緣座體2中，伸入該卡固槽211的上方的縮窄處與該絕緣座體2結合固定，從而使該導電元件1與該絕緣座體2的結合更爲穩定，從而防止脫落。The cross-sectional size of the accommodating groove 21 is adapted to the cross-sectional size of the surrounding portion 14. One of the walls of the accommodating groove 21 further protrudes to two sides to form a locking groove 211, the locking groove 211 Preferably, it is provided on the bottom surface of the insulating base body 2, and the depth of the locking groove 211 is smaller than the height of the insulating base body 2. The locking plate 141 and the two surrounding structures 142 of the surrounding portion 14 are respectively matched with the walls of the containing groove 21. And the clamping thorn 143 of the surrounding portion 14 penetrates into the insulating base body 2 through the fixing groove 211, and extends into the constriction above the fixing groove 211 to be combined and fixed with the insulating base body 2 so that the The combination of the conductive element 1 and the insulating base body 2 is more stable, so as to prevent falling off.

該導電元件1的彎折部13彎折形成的框體131的尺寸較佳是大於該容置槽21的尺寸，從而該彎折部13可以抵接在該絕緣座體2的底面，阻止該導電元件1過度***該絕緣座體2，控制該導電元件1的***深度從而對該導電元件1的裝配起到定位作用。The size of the frame body 131 formed by bending the bending portion 13 of the conductive element 1 is preferably larger than the size of the accommodating groove 21, so that the bending portion 13 can abut against the bottom surface of the insulating base 2 to prevent the The conductive element 1 is excessively inserted into the insulating base 2 to control the insertion depth of the conductive element 1 so as to position the assembly of the conductive element 1.

根據上文的描述，本新型的導電元件1中，其接觸部11呈子彈頭外形，在受到側向力時不容易過度偏擺導致發生非彈性變形，從而具有較好的可靠性和使用壽命。同時，該包圍部14將該蛇形彈性部12包圍於其中，阻止該蛇形彈性部12與該導電元件1所安裝的該絕緣座體2直接接觸，從而避免該蛇形彈性部12在上下伸縮時觸碰到該絕緣座體2造成卡滯，有利於該蛇形彈性部12保持上下方向的伸縮運動能力，提高電接觸的可靠性以及使用壽命。此外，該包圍部14還向外突伸出卡固突刺143，方便與該絕緣座體2固定，提高固定的可靠性。According to the above description, in the conductive element 1 of the present invention, the contact portion 11 is in the shape of a bullet, and it is not prone to excessive deflection and inelastic deformation when subjected to lateral force, thus having better reliability and service life. . At the same time, the surrounding portion 14 encloses the serpentine elastic portion 12 to prevent the serpentine elastic portion 12 from directly contacting the insulating seat body 2 mounted on the conductive element 1, thereby preventing the serpentine elastic portion 12 from being up and down. Touching the insulating seat body 2 during expansion and contraction causes jamming, which is beneficial for the serpentine elastic portion 12 to maintain the ability of expansion and contraction in the vertical direction, and improves the reliability and service life of electrical contact. In addition, the enclosing portion 14 also protrudes outwardly with a securing stud 143 to facilitate fixing with the insulating base body 2 and improve the reliability of fixing.
