Description

電源連接器及其製造方法 Power connector and method of making the same

本發明提供一種電源連接器，尤指一種一體製成的導電端子與絕緣本體一體射出成型的電源連接器及其製造方法。 The present invention provides a power connector, especially a power connector in which conductive terminals and an insulating body are integrally formed by injection molding and a manufacturing method thereof.

如圖1A所示，現有的電源連接器1包括導體11及絕緣本體12。導體11的前段部為車削成型，後段部為冲壓成型，其中冲壓成型只能為平面型態，以現有製程能力無法改善僅有平面型態的結構。導體11的後段部穿過絕緣本體12與導接片13連接。具體而言，現有的電源連接器1都是採用兩件式鉚接方式組合而成，再夾持線材2以形成電性連接。 As shown in FIG. 1A , the conventional power connector 1 includes a conductor 11 and an insulating body 12 . The front section of the conductor 11 is formed by turning, and the rear section is formed by stamping, wherein the stamping and forming can only be in a flat shape, and the structure with only a flat shape cannot be improved with the existing process capability. The rear portion of the conductor 11 is connected to the conductive piece 13 through the insulating body 12 . Specifically, the existing power connector 1 is assembled by a two-piece riveting method, and then the wire 2 is clamped to form an electrical connection.

如圖1B所示，當線材13與導接片12夾持固定後，再進行鉚接作業，以使導體11鉚接固定導接片12。電源連接器1會放置在沖壓下治具(圖略)上並抵接導體11的前段部，而導接片12穿過導體11後以沖壓上治具(圖略)鉚接導體11的後段部。由於導體11的前段部容易受冲擊力量造成前段部導體11擠壓變形，使前段部導體11影響對接連接器(圖略)難以插接或者完全無法對接。兩件式鉚接方式還有另一個無法改善的困難點，就是鉚接方式無法確保導體11的前後段部穩定的限位，有極大的可能在鉚接時造成導體11歪斜。因此，導體11因 為採用鉚接製程，在傳輸訊號或電力時容易造成低傳導、高阻抗情況，進而產生溫升現象，整體傳輸效率降低的問題。 As shown in FIG. 1B , after the wire 13 and the guide piece 12 are clamped and fixed, a riveting operation is performed, so that the conductor 11 is riveted and fixed to the guide piece 12 . The power connector 1 will be placed on the lower punching jig (not shown) and abut the front section of the conductor 11, and the conductive piece 12 will pass through the conductor 11 and then the rear section of the conductor 11 will be riveted with the upper punching jig (not shown). . Since the front section of the conductor 11 is easily subjected to impact force, the front section conductor 11 is squeezed and deformed, so that the front section conductor 11 affects the butt connector (not shown) to be difficult to plug or completely unable to butt. The two-piece riveting method also has another difficulty that cannot be improved, that is, the riveting method cannot ensure the stable position of the front and rear sections of the conductor 11, and there is a great possibility that the conductor 11 will be skewed during riveting. Therefore, the conductor 11 is In order to adopt the riveting process, it is easy to cause low conduction and high impedance during the transmission of signals or power, resulting in a temperature rise phenomenon, and the overall transmission efficiency is reduced.

由於現有的電源連接器1的導體11後段部裸露於絕緣本體12外，若電力突冲或有其他金屬碰觸容易造成短路而造成設備損壞。線材2同樣裸露於電源連接器1外，當受拉扯時也容易斷裂進而造成設備失效。此外，現有的電源連接器1的線材2出線方向受到限制，無法依據客戶/用戶端需求改變。綜上所述，現有的電源連接器1製造方法繁瑣，生產效率低落，無法大量生產，又存在不穩定的加工程序，極有待改善。 Since the rear portion of the conductor 11 of the conventional power connector 1 is exposed outside the insulating body 12 , if there is a power conflict or other metal contacts, a short circuit is likely to be caused and the equipment will be damaged. The wire 2 is also exposed outside the power connector 1 , and is easily broken when pulled, thereby causing the device to fail. In addition, the outgoing direction of the wires 2 of the existing power connector 1 is limited and cannot be changed according to the needs of customers/users. To sum up, the existing power connector 1 manufacturing method is cumbersome, has low production efficiency, cannot be mass-produced, and has unstable processing procedures, which needs to be improved.

本發明的目的，在於提供一種電源連接器，一體成型的導接端子與絕緣本體為埋入射出成型製成，使導接端子具有良好的絕緣保護，改善電力突冲或避免金屬不慎碰觸彎折部/導線造成的短路或設備損壞的問題。 The purpose of the present invention is to provide a power connector, the integrally formed conductive terminal and the insulating body are made of embedded injection molding, so that the conductive terminal has good insulation protection, improves power surge or avoids accidental metal contact Problems with short circuits or equipment damage caused by bends/wires.

本發明的另一目的，在於提供一種電源連接器，當傳輸訊號或電力時具有高傳導、低阻抗，從而改善溫升現象，提高整體傳輸效率。 Another object of the present invention is to provide a power connector with high conduction and low impedance when transmitting signals or power, thereby improving the temperature rise phenomenon and improving the overall transmission efficiency.

本發明另一目的，在於提供一種電源連接器的製造方法，具有簡單的製造程序/步驟、提高生產力效率、可進行大量生產，且大幅改善現有製程方法不穩定的加工程序。 Another object of the present invention is to provide a manufacturing method of a power connector, which has simple manufacturing procedures/steps, improves productivity, can be mass-produced, and greatly improves the unstable processing procedures of the existing manufacturing methods.
