Description
本創作係提供一種電連接器之接地結構,尤指絕緣座體內部為結合有接地片,並由二接地面之片體以搭接部之接地彈片抵持接觸於端子組中接地用之導電端子同時串接形成一共同接地,提升接地傳導的路徑與密度,以確保整體訊號傳輸時之穩定性。 The present invention provides a grounding structure of an electrical connector, in particular, a grounding piece is integrated inside the insulating base body, and the grounding piece of the two grounding surfaces is abutted against the grounding elastic piece of the terminal group by the grounding elastic piece of the overlapping part. The terminals are connected in series at the same time to form a common ground, which improves the path and density of the ground conduction to ensure the stability of the overall signal transmission.
按,一般連接器係使用在電子訊號與電源的連接元件及其附屬配件,主要功能在提供各種電子裝置或設備間之連接,以及確保訊號可準確的傳輸,而連接器隨著其應用的產品、功率與使用的環境等不同,則發展出各種不同的型式,並可應用於電腦、伺服器、電腦周邊設備(如鍵盤、滑鼠、印表機等)、車上主機之周邊設備(如車用電腦、衛星導航等)、電信及通訊設備與家用電器等產品上使用。 Press, the general connector is used in the connection between the electronic signal and the power supply and its accessories, the main function is to provide a connection between various electronic devices or devices, and to ensure that the signal can be accurately transmitted, and the connector with its application products Different from power and environment, it has developed various types and can be applied to computers, servers, computer peripherals (such as keyboards, mice, printers, etc.) and peripheral devices on the car (such as Used in car computers, satellite navigation, etc., telecommunications and communication equipment and household appliances.
再者,由於現今電子產品設計都趨向於輕、薄、短、小,並為了能夠使各種電子產品的體積縮小,電子產品內部之連接器便需更為精密且小型化,整體結構強度亦需要隨之加強,以因應目前之發展趨勢,而一般連接器(如板對板連接器、線對板連接器等)通常會利用一個公端連接器及一個母端連接器進行配合對接,並將訊號或電源透過電路板傳送至控制電路中,以執行相應的操作功能,當公端連接器及母端連接器的座 體對接時,可將公座與母座上之端子組相互抵持接觸,從而實現二平行相對的電路板或線纜與電路板間之電性連接等。 Furthermore, since today's electronic product designs tend to be light, thin, short, and small, and in order to reduce the size of various electronic products, the connectors inside the electronic products need to be more precise and miniaturized, and the overall structural strength is also required. Intensified, in response to current development trends, and general connectors (such as board-to-board connectors, wire-to-board connectors, etc.) usually use a male connector and a female connector for mating and The signal or power is transmitted to the control circuit through the circuit board to perform the corresponding operation function, when the male connector and the female connector are seated When the body is docked, the terminal sets on the male seat and the female seat can be brought into contact with each other, thereby achieving electrical connection between the two parallel opposing circuit boards or cables and the circuit board.
此外,連接器除了設計越來越微小化之外,對於傳輸速度及頻寬的要求也越來越高,相形之下高頻訊號傳輸所產生的問題更是層出不窮,並隨著連接器的微小化和傳輸速度的大幅提升,其端子組的數目增多且分佈也更為密集,極容易因相鄰端子間距離過於接近而造成高頻訊號傳輸時之電磁波及串音干擾等,未來還會以更快速度成長,使連接器本身之訊號干擾問題將會更加嚴重,對於高頻連接器而言,在許多訊號完整性的問題中,尤其以串音(Cross-talk)干擾的問題最為嚴重,而傳統的高頻連接器包括絕緣本體、安裝於絕緣本體內之上下排端子中的複數接地端子,以及將該些接地端子串接在一起之接地片,惟該接地片之結構複雜,並需先與絕緣材質製成之卡合件進行組裝,才能透過卡合件進一步安裝在絕緣本體內部,同時將接地片之彈臂分別抵觸於接地端子上進行串接形成共同接地,此種接地片透過卡合件安裝於絕緣本體內部的方式其構件與組裝步驟過多且較為不便,亦會造成生產與組裝成本無法降低,而有待從事於此行業者重新設計來加以有效解決。 In addition, in addition to the increasingly miniaturized design of the connector, the requirements for transmission speed and bandwidth are also getting higher and higher. The problems caused by high-frequency signal transmission are endless, and the connector is tiny. The speed of transmission and transmission is greatly increased, and the number of terminal groups is increased and the distribution is more dense. It is very easy to cause electromagnetic waves and crosstalk interference during high-frequency signal transmission due to the close proximity between adjacent terminals. Faster growth, the signal interference problem of the connector itself will be more serious, for high-frequency connectors, in many signal integrity problems, especially cross-talk interference is the most serious problem. The conventional high-frequency connector includes an insulating body, a plurality of grounding terminals mounted in the lower row of terminals in the insulating body, and a grounding piece for connecting the grounding terminals in series, but the structure of the grounding piece is complicated and needs to be Firstly assembled with the engaging member made of insulating material, and then can be further installed inside the insulating body through the engaging member, and the elastic arms of the grounding piece are respectively in contact with the grounding. The series is connected in series to form a common ground. The grounding piece is mounted on the inside of the insulating body through the engaging member. The component and assembly steps are too many and inconvenient, and the production and assembly costs cannot be reduced. The industry has redesigned it to solve it effectively.
故,新型創作人有鑑於上述習用之問題與缺失,乃搜集相關資料經由多方的評估及考量,並利用從事於此行業之多年研發經驗不斷的試作與修改,始有此種電連接器之接地結構的新型誕生。 Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected the relevant materials through various evaluations and considerations, and have used the trial and modification of many years of R&D experience in this industry to start the grounding of such electrical connectors.
