[Prior Art]
電子電路之設計者通常會關注於兩個基本電路部分，即邏輯（或 信號）部分以及電源部分，且在設計邏輯電路時，因為在邏輯電路中 流動之電流較低’使得設計者通常不會考慮由於狀態改變所造成（如： 溫度）在電氣屬性令之任何變化（如：電路元件之阻抗），然而，高電 流之流動將使得電源電路在電氣屬性上會產生變化，因此針對使用於 電源電路中而設計之電力連㈣必麵夠散熱（主要由焦耳效應所產 生），使得因電流改變所造成之電氣屬性變化可有效減至最低。 美國專利第US7,374,43g號揭示了 一種傳輸電力之電力連接器 件，這種電力連接器元件由安裝於電路板上相互配對插接之插座連 器和插頭連接H域，插座連接H包括插舰緣本體和組裝在插座 緣本體内之母端子組，_連接純括_絕緣本趙和喊在插頭 緣本體内之公端子組。參考第—圖，每—母端子414均包括頂侧相 之兩片式大面積之平板狀本體418、42〇和從本體前側向前延伸形成 上下兩片對接臂43〇、432。當插座連接器與插頭連接器相互對接 形成電性導通時，公、母端子之對接臂相互雜，母端子似^ γ端子插人時之_力崎生變形，而母端子414之平板狀本體 仙、420之上端^型連接部分似、似可以提供—定之反作用^ 撐力，有助於保持母端子414之接觸部分不因受力 該專賴，飽刪^ 3 201027851 構，此結構需要先衝壓出端子主體部然後再折彎，此折彎制程常會造 成端子折彎處龜裂，進而影響材料電導特性而降低品質，且折彎後端 子因焊接時受高·響造成金屬城力釋放，造成端子外擴影響焊腳 正位度，導致與電路板接合時出現不順暢或連接器焊腳折腳現象。另 外，母端子4M採用U型結構，其製作過程複雜，並且成本較高。 第圖中，母端子414只能從絕緣本體下部插入，側蓋eg由母 端子414勤之卡扣部將其固持在絕緣本體412中，卡扣後另需卡塊 468與母端子414麻之凹祷配合，防止母端子414上下活動影響和 公連接器之連接，此種固持結構比較複雜^前述，電力連接器需要 具備良好之散熱功能，側蓋438蓋上後會使母端子414暴露在空氣中 之部分變小，影響了電力連接器在卫作過程中之散熱功能。 所以，針對此類電力連接器結構，仍有進一步改進之空間。 【發明内容】 本發明之目的在於提供—種備構及製作簡單且具備更好散熱效 果之電力連接器。 本發明另-目的在於難_種具有低成本之導電端子且電力傳輸 穩定之電力連接器。 為了實現上述目的，本發明之一種實施方式之一種電力連接器， 其包括設有絲通道之絕緣本體、收容於收容通道巾之端子，所述端 子包括主趙部和尾部，其巾，所述電力連翻還包括由端子之主體部 一端插接到所述絕緣本體之蓋體。 作為本發明之進—步改進，所述蓋體包浦伸之可卡持於絕緣本 體之鎖緊部，鎖緊部上設有凸出部。 4 201027851 作為本發·明夕冰Designers of electronic circuits typically focus on two basic circuit parts, the logic (or signal) part and the power supply part, and when designing the logic circuit, because the current flowing in the logic circuit is low, the designer usually does not Consider any change in electrical properties (eg, impedance of circuit components) due to state changes (eg, temperature). However, high current flow will cause changes in the electrical properties of the power supply circuit, so it is intended for use in power supplies. The power connection designed in the circuit (4) must be sufficient for heat dissipation (mainly caused by the Joule effect), so that the change of electrical properties caused by the current change can be effectively minimized. US Pat. The ship's edge body and the female terminal set assembled in the socket body, _ connection purely _ insulation Ben Zhao and shouted in the plug terminal body of the male terminal set. Referring to Fig. 1, each of the female terminals 414 includes a two-piece large-area flat-shaped body 418, 42A on the top side and a front-side extension from the front side of the body to form upper and lower butt-joint arms 43A and 432. When the socket connector and the plug connector are electrically connected to each other to form electrical conduction, the butt arms of the male and female terminals are mutually mixed, the female terminal is like the γ terminal inserted when the γ terminal is inserted, and the flat terminal body of the female terminal 414 is deformed. The connection between the upper end of the 420 and the 420 is similar, and it seems to provide a certain reaction. It helps to keep the contact part of the female terminal 414 from being affected by the force, and the structure is needed. The main body of the terminal is punched out and then bent. This bending process often causes cracks in the bent portion of the terminal, thereby affecting the electrical conductivity characteristics of the material and reducing the quality, and the terminal is bent due to the high metal ring force during welding. The expansion of the terminal affects the positive position of the soldering leg, resulting in a smoothness when the board is engaged or a phenomenon in which the connector is bent. In addition, the female terminal 4M adopts a U-shaped structure, which is complicated in manufacturing process and high in cost. In the figure, the female terminal 414 can only be inserted from the lower part of the insulating body, and the side cover eg is held by the female terminal 414 in the insulative housing 412. After the buckle, the female block 468 and the female terminal 414 are required. The concave prayer cooperates to prevent the upper and lower movements of the female terminal 414 from affecting the connection with the male connector. The holding structure is relatively complicated. As described above, the power connector needs to have a good heat dissipation function, and the side cover 438 is covered to expose the female terminal 414. The part of the air becomes smaller, which affects the heat dissipation function of the power connector during the maintenance process. Therefore, there is still room for further improvement in the structure of such a power connector. SUMMARY OF THE INVENTION It is an object of the present invention to provide a power connector that is easy to fabricate and that is simple to manufacture and that has better heat dissipation. Another object of the present invention is to provide a power connector having a low-cost conductive terminal and stable power transmission. In order to achieve the above object, an electrical connector according to an embodiment of the present invention includes an insulative housing provided with a wire passage, and a terminal received in the receiving passage, the terminal including a main portion and a tail portion, and a towel thereof The power connection further includes a cover body that is inserted into the insulative housing from one end of the main body portion of the terminal. As a further improvement of the present invention, the cover body can be held by the locking portion of the insulating body, and the locking portion is provided with a protruding portion. 4 201027851 As the hair, Ming Xi Bing
