However, the contact portion of the conductive terminal is at the free end of the terminal strip, which is prone to deformation during the punching process, resulting in poor flatness, and in the subsequent injection molding process, since the terminal strip is only fixed at one end, it is free. The contact portion of the end is susceptible to the flow impact of the liquid plastic and deviates from the predetermined position, making it difficult to achieve automated production.
是以，針對上述問題，有必要對現有技術進行改造。 Therefore, in order to solve the above problems, it is necessary to modify the existing technology.

參第二圖所示，為一種USB 3.0堆疊式電連接器200，該電連接器200包括絕緣本體及包覆絕緣本體的遮蔽殼體203。絕緣本體與遮蔽殼體203將電連接器200分割為第一收容空間201及位於第一收容空間201上方的第二收容空間202。第一收容空間201內設有第一舌板2010及固持於第一舌板2010上的第一導電端子，第二收容空間內設有第二舌板2020及固持於第二舌板2020上的第二導電端子。第一舌板2010與第二舌板2020係組裝在絕緣本體上。本發明端子料帶中的導電端子即為所述第一導電端子或第二導電端子。但是，本發明端子料帶並不限於應用於本實施例中的USB 3.0電連接器，也可應用於其他電連接器。 As shown in the second figure, it is a USB 3.0 stacked electrical connector 200. The electrical connector 200 includes an insulative housing and a shielding housing 203 covering the insulative housing. The insulative housing and the shielding housing 203 divide the electrical connector 200 into a first receiving space 201 and a second receiving space 202 located above the first receiving space 201 . The first receiving space 201 is provided with a first tongue plate 2010 and a first conductive terminal fixed on the first tongue plate 2010. The second receiving space is provided with a second tongue plate 2020 and is fixed on the second tongue plate 2020. Second conductive terminal. The first tongue 2010 and the second tongue 2020 are assembled on the insulative body. The conductive terminal in the terminal strip of the present invention is the first conductive terminal or the second conductive terminal. However, the terminal strip of the present invention is not limited to the USB 3.0 electrical connector used in the embodiment, and can be applied to other electrical connectors.
參第三圖所示，本發明端子料帶100包括沿縱長方向延伸的第一連接帶1、與第一連接帶1相對並大致平行的第二連接帶2及位於第一連接帶1與第二連接帶2之間至少一端子排3。該端子排3包括複數第一導電端子4，每一第一導電端子4包括連接第一連接帶1的焊接部41、靠近第二連接帶2的接觸部43及連接焊接部41與接 觸部43的固持部42。在固持部42靠近接觸部43處，所述端子排3設有連接所有第一導電端子4的連接部31，該連接部31與第一連接帶1平行設置，第二連接帶2延伸出接合部21與連接部31相連。所述第一連接帶1與第二連接帶2上各設有沿縱長方向間隔設置的複數定位孔5。由於連接部31臨近接觸部43，在沖壓過程中連接部31的連接作用可防止各接觸部43相互變形偏離，並且第二連接帶2進一步對連接部31具有支撐作用，從而保證接觸部43平面度良好。端子料帶100沖壓好後需要放置在注塑機(未圖示)內與第一舌板2010一體成型。端子料帶100通過第一連接帶1與第二連接帶2上的定位孔5定位固持在注塑機內，為了防止端子料帶100在注塑過程中意外脫落，第一連接帶1設有向下彎折的固持片11以更好的固持於注塑機內。當然，第二連接帶2也可設置向下彎折的固持片以加強固持效果。由於具有第二連接帶2的進一步定位牽引作用，導電端子的接觸部43不易因液態塑膠的流動沖擊而導致偏離預定位置，成型良率穩定，適用於自動化生產。 As shown in the third figure, the terminal strip 100 of the present invention comprises a first connecting strip 1 extending in the longitudinal direction, a second connecting strip 2 opposite to the first connecting strip 1 and substantially parallel, and a first connecting strip 1 and At least one terminal row 3 between the second connecting strips 2. The terminal block 3 includes a plurality of first conductive terminals 4, each of which includes a soldering portion 41 connecting the first connecting strip 1, a contact portion 43 adjacent to the second connecting strip 2, and a connecting soldering portion 41. The holding portion 42 of the contact portion 43. The terminal block 3 is provided with a connecting portion 31 connecting all the first conductive terminals 4 at a position close to the contact portion 43 of the holding portion 42, the connecting portion 31 being disposed in parallel with the first connecting strip 1, and the second connecting strip 2 extending and engaging The portion 21 is connected to the connecting portion 31. The first connecting strip 1 and the second connecting strip 2 are each provided with a plurality of positioning holes 5 spaced apart in the longitudinal direction. Since the connecting portion 31 is adjacent to the contact portion 43, the connecting action of the connecting portion 31 during the pressing process prevents the respective contact portions 43 from being deformed from each other, and the second connecting belt 2 further supports the connecting portion 31, thereby ensuring the plane of the contact portion 43. Good. After the terminal strip 100 is stamped, it needs to be placed in an injection molding machine (not shown) integrally formed with the first tongue 2010. The terminal strip 100 is positioned and held in the injection molding machine through the positioning holes 5 on the first connecting strip 1 and the second connecting strip 2, and the first connecting strip 1 is provided downward in order to prevent the terminal strip 100 from accidentally falling off during the injection molding process. The bent retaining piece 11 is better retained in the injection molding machine. Of course, the second connecting strip 2 can also be provided with a downwardly bent holding piece to enhance the holding effect. Due to the further positioning and pulling action of the second connecting strip 2, the contact portion 43 of the conductive terminal is not easily deviated from the predetermined position due to the flow impact of the liquid plastic, and the molding yield is stable, and is suitable for automated production.
參第四圖所示，為涉及第二導電端子4’的端子料帶100’’，該端子料帶100’’與端子料帶100結構大致相同，不作詳細描述，只對差別部分作詳細說明。由於第二導電端子4’連接至電路板(未圖示)的距離大於第一導電端子4連接至電路板的距離，因此，第二導電端子4’的固持部42’相較第一導電端子4的固持部42更長，為了防止沖壓過程中，相鄰端子相互散開，端子排3’’在固持部42’上設有第二連接部32將所有第二導電端子4’’連接在一起。該第二連接部32與第一連接帶平行。進一步，第二連接部32設有向下彎折的第二固持片321，以更好固持於注塑模具內。當然，連接部31上也可設置第二固持片。本發明具體實施 方式並不對其構成限制。 As shown in the fourth figure, the terminal strip 100'', which is related to the second conductive terminal 4', has the same structure as the terminal strip 100. It will not be described in detail, and only the difference will be described in detail. . Since the distance that the second conductive terminal 4' is connected to the circuit board (not shown) is greater than the distance that the first conductive terminal 4 is connected to the circuit board, the holding portion 42' of the second conductive terminal 4' is compared with the first conductive terminal. The holding portion 42 of the 4 is longer. In order to prevent the adjacent terminals from spreading apart during the stamping process, the terminal block 3'' is provided with a second connecting portion 32 on the holding portion 42' to connect all the second conductive terminals 4'' together. . The second connecting portion 32 is parallel to the first connecting strip. Further, the second connecting portion 32 is provided with a second holding piece 321 which is bent downward to be better held in the injection mold. Of course, the second holding piece may also be disposed on the connecting portion 31. Detailed implementation of the present invention The method does not limit it.
參第五圖所示，為端子料帶100與第一舌板2010一體注塑完成後的示意圖。所述第一舌板2010設有自上向下貫穿且排成一排的複數通孔2011，所述連接部31在兩相臨第一導電端子4之間的連接部分剛好位於通孔2011內，這樣可以通過沖模(未圖示)將連接部分沖切掉從而使相鄰的第一導電端子4彼此分離。另外，第一舌板2010縱長方向的兩側分別設有凹部2012，該凹部2012向下貫穿第一舌板下表面，連接部自凹部2012延伸而出，這樣連接部被沖斷後可自凹部2012抽出，避免了在第一舌板外側切斷連接部而造成殘餘末端與遮蔽殼體203接觸，導致信號傳輸失效。第二舌板2020與端子料帶100’’一體注塑完成後的結構與第一舌板2010大致相同，在此不再詳細說明。 Referring to FIG. 5, it is a schematic view after the terminal strip 100 and the first tongue 2010 are integrally molded. The first tongue plate 2010 is provided with a plurality of through holes 2011 penetrating from top to bottom and arranged in a row, and the connecting portion of the connecting portion 31 between the two adjacent first conductive terminals 4 is located in the through hole 2011. Thus, the connecting portion can be punched off by a die (not shown) to separate the adjacent first conductive terminals 4 from each other. In addition, the two sides of the first tongue plate 2010 in the longitudinal direction are respectively provided with a recessed portion 2012 which penetrates downwardly through the lower surface of the first tongue plate, and the connecting portion extends from the recessed portion 2012, so that the connecting portion can be self-retracted after being broken The withdrawal in 2012 avoids the cutting of the joint on the outside of the first tongue and causes the residual end to come into contact with the shield shell 203, resulting in failure of signal transmission. The structure in which the second tongue 2020 and the terminal strip 100'' are integrally molded is substantially the same as that of the first tongue 2010, and will not be described in detail herein.
