DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to the field of electrical connectors for electrically connecting printed circuit boards (pcs); in particular, to a durable electrical connector that provides reliable electrical connections And prevent solder wicking. [Prior Art]
Ο 電連接器被應用於各種應用中，其通常於兩個印刷電 路板（PCB)之間提供一電連接。電連接器之一常用實例被 稱為板對板連接器。一典型板對板連接器包括兩個組件， 一公連接器及一母連接器，每個連接器被安裝在各自的板 上以便被電連接到一起。該公連接器和母連接器被設計成 在插人過程中彼此鳴合。儘管該公連接器通常被插入到該 母連接器，反之，亦可應用。 一 '六—狄價之殼體，公連接器 通常通過插人在該狹槽中與母連接器匹配。除了該狹槽， 該母連接器包括複數個傳導 —壯1 H 5亥專傳導終端將在其上 女裝母連接器之PCB電連接 , ^ ^ ν 轶主&連接态，並因此連接至在 八上文裝公連接器的對應的Ρ(：Β。 矽笠if缸加士 母連接态的情況下’ 該4複數個傳導終端通常 一段柏a i 破配置於任-側且沿該狹槽分佈 丰又相备長之長度。兩個連續 距，卽故☆山， 貝得V終柒之間之間隔稱為間 即終^到終端的間隔。 每個傳導終端通常 端的末端部分在電氣上 PCB安裴點。另一方面 包括一末端部分和 和實體上將連接器 ，接觸部分在母連 一接觸部分。終 4接到其各自的 接器和插入的公 5 200818612 連接器之間建立電氣上和實體上的連接。通常藉由焊接將 末端部分固定到P C B。上述參照母連接器描述之該等終端 與殼體之技術功能亦適用於公連接器，只是公連接器之設 計與母連接器之狹槽是互補的。 在早期類型之連接器中，通常藉由例如壓配合將終端 插入殼體中的預成形開口。壓配合用於將傳導終端固定到 連接器。但是，壓配合之缺點在於將多個傳導終端壓入每 個連接器時非常煩瑣，尤其是在單個連接器中包含的終端 數量不斷增加（即間距不斷減小）時。另一缺點在於為插 入該等傳導終端，必須為殼體設計“充分的間隔”以允許 終端的精確插入和壓配合。“充分的間隔”通常為在其中 插入終端之通孔形式。結果，通過插入終端的末端部分將 連接器焊接到其各自的PCB。但是，具有通孔時易產生焊 料爬越。焊料爬越係指焊接合金沿終端之末端部分及沿接 觸部分向上爬行。發生焊料爬越會導致對殼體的破壞，並 亦可能在連接器内部造成短路。 為克服焊料爬越的缺點，已廣泛採用在殼體生產過程 中插入終端焊接之方法。如美國專利第6 0 1 0 3 7 0號中之所 述，在插入焊接中，首先從薄金屬料衝壓一組終端，並以 如藉由模具設計所確定之一間距設定於一模具内。然後閉 合模具，模製材料進入以形成殼體，並在其中嵌入該等傳 導終端。這導致在一連接器中，雖然該終端保持為單件， 但通過形成該殼體之模製材料，該末端部分被考慮獨立於 該接觸部分（即無間隙或通孔）。因此，防止了焊接合金沿 6 200818612 傳導終端向上爬越。 美國專利第60 1 03 70號揭示了 一種通過具有一殼體 插入模製所製造之電連接器，該殼體具有一對側壁和端 以界定一槽。在每個殼體中安裝複數個接觸終端，每個 端具有一焊接部分和一接觸部分，以及一殼體嚙合部分 焊接部分自殼體底部向外延伸，以用於連接到P C B。接 部分接在焊接部分後面，它垂直向上對齊，並自底部沿 壁内表面高度延伸，並與殼體嚙合部分端接。殼體嚙合 分被固定到側壁頂部，並將終端固定就位。 美國專利第6 1 5 5 8 8 6號亦揭示一種藉由插入焊接法 造之電連接器。在此美國專利中所描述之電連接器包括 絕緣殼體，其具有一沿該殼體之一段相當長度延伸之細 槽。複數個孔亦沿該槽之上部分長度分佈，每個孔適合 於接收一終端。每個終端具有一末端部分、一端部分以 其間之一接觸部分。該末端部分自該殼體之底部突出， 該接觸部分沿該槽之一内壁對齊。每個孔容納該終端之 部分，以便該末端部分自該接觸部分垂直向上突出。 歐洲專利第EP 0 6 9 3 8 0 2 B 1號亦揭示一種插入模 之連接器。此連接器具有一具有一縱向狹槽之殼體。該 槽沿該殼體延伸相當一段長度並延伸到該殼體之底部。 在美國專利第6 1 5 5 8 8 6號中之所述，該連接器亦包括沿 狹槽之長度平行配置之終端，每個終端具有一末端部分 一端部分以及其間之一接觸部分。該末端部分自該殼體 一下部分延伸，以附接到一 P C B，而該接觸部分被配置 之 壁 終 〇 觸 側 部 製 長 用 及 而 端 製 狹 如 該 之 成 7Ο Electrical connectors are used in a variety of applications, which typically provide an electrical connection between two printed circuit boards (PCBs). A common example of an electrical connector is referred to as a board-to-board connector. A typical board-to-board connector includes two components, a male connector and a female connector, each connector being mounted on a respective board for electrical connection. The male connector and the female connector are designed to sing each other during the insertion process. Although the male connector is usually inserted into the female connector, the reverse is also applicable. A 'six-divalent housing, the male connector is usually mated with the female connector in the slot. In addition to the slot, the female connector includes a plurality of conductive-strong 1 H 5 Hai-conducting terminals to be electrically connected to the PCB of the female connector, ^ ^ ν 轶 main & connected state, and thus connected to In the case of the corresponding Ρ (: Β 矽笠 if 缸 加 加 连接 连接 ' ' ' ' ' ' ' 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该The length of the distribution is long and the length of the length is two. The distance between the two consecutive distances, 卽 ☆ ☆, and the end of the 得 V, is called the interval between the end and the end. The end of each conduction terminal is electrically PCB mounting point. On the other hand, it includes an end portion and a physical connector, the contact portion is in the contact portion of the female connector. The final 4 is connected to its respective connector and inserted into the male 5 200818612 connector to establish electrical The connection between the upper and the physical. The end portion is usually fixed to the PCB by soldering. The technical functions of the terminal and the housing described above with reference to the female connector are also applicable to the male connector, but only the design and the female connection of the male connector The slots of the device are complementary. In prior types of connectors, the terminal was typically inserted into a pre-formed opening in the housing by, for example, a press fit. A press fit is used to secure the conductive termination to the connector. However, the disadvantage of press-fitting is that multiple conductive terminals are pressed It is very cumbersome to enter each connector, especially when the number of terminals included in a single connector is increasing (ie, the spacing is decreasing). Another disadvantage is that for the insertion of these conductive terminals, the housing must be designed "full" "Interval" to allow precise insertion and press fit of the terminal. "Sufficient spacing" is typically the form of a through hole in which the terminal is inserted. As a result, the connector is soldered to its respective PCB by inserting the end portion of the terminal. Solder creep occurs when the hole is used. Solder creep means that the solder alloy crawls upward along the end portion of the terminal and along the contact portion. The occurrence of solder creep may cause damage to the case and may cause a short circuit inside the connector. Overcoming the shortcomings of solder climbing, the method of inserting terminal soldering in the production process of the housing has been widely used. For example, U.S. Patent No. 6 0 1 0 3 As described in No. 70, in insert welding, a set of terminals is first stamped from a thin metal material and set in a mold at a distance as determined by the mold design. Then the mold is closed and the molding material enters. Forming a housing and embedding the conductive terminals therein. This results in a connector that, although held in a single piece, is formed to be independent of the contact portion by forming a molding material for the housing (ie, no gaps or through holes). Therefore, the solder alloy is prevented from climbing up the conductive terminal along the 6 200818612. U.S. Patent No. 60 1 03 70 discloses an electrical connector manufactured by insert molding with a housing, The housing has a pair of side walls and ends to define a slot. A plurality of contact terminals are mounted in each housing, each end having a solder portion and a contact portion, and a housing engaging portion soldering portion from the bottom of the housing Extend outward for connection to the PCB. The connector is connected behind the welded portion and is vertically aligned upwardly and extends from the bottom along the inner surface of the wall and terminates in engagement with the housing. The housing engaging portion is fixed to the top of the side wall and the terminal is held in place. An electrical connector made by insert welding is also disclosed in U.S. Patent No. 6, 1 5 5 8 8 6 . The electrical connector described in this U.S. patent includes an insulative housing having a slot extending along a substantial length of a section of the housing. A plurality of apertures are also distributed along the length of the upper portion of the slot, each aperture being adapted to receive a terminal. Each terminal has an end portion and an end portion with a contact portion therebetween. The end portion projects from the bottom of the housing, the contact portion being aligned along an inner wall of the slot. Each of the holes accommodates a portion of the terminal such that the end portion projects vertically upward from the contact portion. A connector for inserting a mold is also disclosed in European Patent No. EP 0 6 9 3 8 0 2 B1. The connector has a housing having a longitudinal slot. The slot extends a length along the housing and extends to the bottom of the housing. The connector also includes terminals disposed in parallel along the length of the slot, each of which has an end portion of one end portion and a contact portion therebetween, as described in U.S. Patent No. 6,158,8,. The end portion extends from a lower portion of the housing to attach to a P C B , and the contact portion is configured to have a wall that is configured to be used for the distal end portion and that is narrower than the end portion.

As described above, the contact portion is terminated with a sub-portion wherein the end portion is bent to be substantially convex and enters a recess at an upper portion of the slot. Although the insert molding method overcomes the problem of solder creepage, it introduces a problem: ensuring that the insert molding ends in a housing are properly fixed so that the terminals remain durable and do not apply when a force is applied thereto. Peel off. Examples of deformation and spalling may occur gradually as a male connector is narrowed in and removed from a male connector. Accordingly, there is still a need for an electrical connector that includes a terminal that is securely secured therein and that is resistant to deformation or spalling. In addition, there is a need for a connector that is cost effective for production. In this regard, a connector that overcomes the above difficulties is defined within the scope of the appended claims. SUMMARY OF THE INVENTION One embodiment of an electrical connector of the present invention includes an insulative housing having two opposing side walls and two opposing end walls, wherein each of the side walls and end walls has an inner surface. The side walls and end walls define a slot. The slot is capable of receiving a complementary electrical connector. The electrical connector having a slot is also commonly referred to as a female electrical connector. The female electrical connector also includes a plurality of conductive terminals. The conductive termination intervals are configured along the length of each side wall. This spacing relationship is also referred to and is typically less than 1.0 mm. Although there may be more than 1.0 mm, the current industry trend is toward a smaller distance. In any event, the conductive terminations of any embodiment of the present invention do not exclude that the ends are located in the other end of the deformation slot in the pair, in the electrical connector. The alignment of these terminals is at a pitch, and the situation has 8 200818612 1. 〇 mm or more. Each of the conductive terminals includes an end portion and a contact portion, wherein the end portion and the contact portion are integrally formed as a single piece. The end portion extends outwardly from the bottom region of the slot for attachment to a circuit board. The contact portion establishes a contact surface between the electrical connector and its complementary electrical connector and includes a first sub-portion and a second sub-portion. The first sub-portion is located between the end portion and the second sub-portion. The first sub-portion contacts at least the side wall and extends upwardly at least substantially perpendicularly in a first direction along the height of the side wall through the bottom of the housing of the female connector. The second sub-portion is bent or bent into the slot to define a U-shaped flexure spring by bending the first and second sub-portions by the first and second sub-portions or, more specifically . In other words, one of the U-shaped arms is formed by the first sub-portion, and the other sub-arm is formed by the second sub-portion. The intermediate portion of the U-shape can be formed entirely by the first sub-portion, the second sub-portion, or a combination thereof. The second sub-portion (which forms one of the arms of the U-shaped flexure spring) extends at least substantially vertically downward in a second direction along the inner surface height of the side wall and terminates at a free end. The second direction is taken from a direction substantially opposite to the first direction. In one embodiment of the female connector of the present invention, a first sub-portion of each of the plurality of conductive terminals is embedded within the sidewalls. This is usually accomplished by an insert welding process, which will be described in detail later. In this particular embodiment, the first sub-portion extends generally along the height of the side wall such that it is at least substantially coplanar with the side wall. In this embodiment, the second sub-portion tends to be adjacent to or in contact with the inner surface of the side wall after being bent into the slot and on the lateral surface of the top portion 9 200818612 of the side wall. In place of the specific embodiment, the first sub-portion of each of the plurality of conductive ends is formed adjacent to the sidewalls. In a particular embodiment, the first sub-portion extends along the height of the inner surface of the side wall and is also at least substantially parallel to the height of the side wall. The first sub-portion may be attached to the inner surface of the side wall or may be in contact only but not fixed thereto. Although the first sub-portion is not embedded in the interior of the side wall, it can be formed by insert molding as long as at least the end portion of the conductive terminal is insert molded in the side wall region near the bottom of the groove. In a particular embodiment, after the second sub-portion is bent to form the substantially U-shaped flexure spring, the second sub-portion tends to extend downwardly toward the bottom of the slot, and tends to be the first The subsections are adjacent or even in contact. In general, the U-shaped flexural spring formed by the first sub-portion of the contact portion and the second portion allows the second sub-port to flex between a compressed state and a released state. This compressed state is reached when the complementary electrical connector is inserted into the slot of the connector. Therefore, the preset state of the second sub-portion is in a released state. In a particular embodiment in which the first sub-portion is embedded in the female connector of the wall, the compressed state generally causes the second sub-port to approach or even contact the inner surface of the sidewall. The release state of the second sub-portion in this embodiment is thus at least slightly offset from the inner surface of the slot, although the second sub-portion remains in contact with the surface of the side wall. In a specific embodiment in which the first sub-portion is connected to the female surface adjacent to the inner surface of the side wall, the compressed state of the second sub-portion (as described above, the sub-segment is extended Dispensing the body to the internal device) 10 200818612 tends to approach the inner surface of the side wall but is not in contact therewith. In contrast, in an in vivo embodiment, the second sub-portion can be the first sub-portion when in a compressed state. In another embodiment, the second sub-portion may be closer to the inner surface of the side wall, but not to the first sub-portion. Therefore, if the example is taken as defining the compressed state and the release-like limit, The compressed state of the second sub-portion can also be between the above examples. In another embodiment of a female connector, the faces of the side walls include a plurality of grooves or slots that are adapted for receiving and/or engaging The curved second subsection of the plurality of conductive terminals. For example, in the words _ these grooves can be tapered or zigzag. This will help and provide the guiding device when the second sub-portion is bent into this. Alternatively, and in the particular embodiment in which a sub-portion is adjacent to the side wall, the grooves are adapted to receive and/or engage the first sub-portion, the second sub- or the first and the first therein The second subsection. In one embodiment of a female connector, the bottom of the slot can include a pair of slots (i.e., two slots). Each slot generally extends along the slot and is located adjacent the sidewalls. The slots are adapted to secure the free end of the curved second subsection. Alternatively, the slot portion can have a plurality of recesses designed to receive the free end of the second sub-portion of the talk end therein. As with the slots, the plurality of slots can generally span the length of the slot. As described above, each of the conductive terminals includes an end portion. In all of the embodiments described herein, the end portion is from the bottom region (i.e., from the region under the slot or substantially adjacent to the one of the contact bends. The upper portion of the slot is also extended, and the bottom portion of the slot is extended to the end of the slot and the periphery of the slot of the slot at the bottom of the slot. In a specific embodiment, the end portion can extend parallel to the sidewall or straight to the sidewall from the bottom of the slot. In an alternate embodiment, the end portion extends from the bottom of the side wall and in a direction generally perpendicular to the side wall (i.e., generally parallel to the bottom plane). Although in some aspects the electrical connector (which is the configuration and formation of the conductive terminals) is described with respect to a sidewall, it should be understood that each of the plurality of conductive terminals on a first sidewall There is a corresponding conductive terminal on a second side C / , and the direction of the corresponding conductive terminal is a mirror image thereof. Accordingly, the same description applies to all aspects of the invention of the second side wall and to the corresponding terminals present therein. As described above, the female connector has a complementary connector called a male connector, which will be described below. The male electrical connector includes a mating portion having a top surface and at least two mating surfaces adapted to mate with the slots of the female electrical connector. The matching surfaces are generally perpendicular to the top surface on the large Q. The male electrical connector also includes a plurality of conductive ends. The conductive terminals are disposed along the mating surface in a spaced relationship and are disposed in the conductive terminals of the slots of the female electrical connector. ^ The configuration of the conductive terminals in the male connector is such that when the matching portion * the slot of the female electrical connector is matched, the conductive terminals along the length of the matching surfaces at least contact their corresponding (the female electrical connector) Conduction Terminal In other words, the distance between the male connectors corresponds to the distance between the terminals in the female connector. Each of the plurality of conductive terminals of the matching portion includes a terminal portion and a contact portion, each of which is formed in a unitary manner. The end portion extends outwardly from the top surface area for attachment to a circuit board. The contact portion has a first sub-portion and a second sub-portion and the first sub-portion is located between the end portion and the second sub-portion. The contact portion establishes a contact surface between the electrical connector and the slot. The first sub-port contacts and extends at least substantially perpendicularly in a first direction away from the top portion along the height of the mating surfaces. And the second sub-portion is curved in a manner that is at least substantially transverse to the length of the mating surfaces. This results in a substantially U-shaped flexure spring defined by the first and second sub-portions. The second sub-portion also extends at least substantially perpendicularly along a height of the mating portion in a second direction opposite the first direction to terminate at a free end. The end portion is typically from a top surface region of the mating portion in a manner similar to the end portion associated with the female connector (directly from the top surface or from an area of the mating surface substantially adjacent the top surface) Extend outward. In a specific embodiment t, the end portion of the male connector can extend from the top surface. In another embodiment, the end portion can extend from the mating surfaces in a direction generally perpendicular to the mating surface (i.e., in a plane generally parallel to the top surface).

The slot 7 is adapted to receive a complementary electrical connector (not shown). A plurality of lead terminals are disposed along the length of each side wall 7 in a spaced relationship. Each of the conductive terminals includes a contact portion 194 and an end portion 1 1 . In the exemplary embodiment, the conductive terminals are inserted into the side walls 17 of the housing such that the end portion 1 1 A vertical direction extends outwardly from the bottom of the side wall 17. The contact portion of the conductive terminal has a height extending perpendicularly from the side wall 17 and protrudes from the top side of the side wall 17. The protruding portion of the contact portion is then bent into the slot 7 to form a substantially U-shaped flexure spring. The U-shaped flexure spring on the body will be discussed in more detail below. The projecting portion of the contact portion bent into the slot 7 terminates at a free end which is received in a recess 9 in the bottom of the slot 7. 2A-2C illustrate a cross section (along the line Χ-Χ along the first figure) of an exemplary embodiment of the female interconnector according to Fig. 1. From this cross-sectional view, the connector (female) has a housing including a pair of side walls 17 and a pair of walls (not shown). The side walls 17 define a slot therebetween and a bottom portion 11 adapted to receive a complementary electrical connector (i.e., a male connector). The electrical connector also includes a plurality of conductive terminals, each of which includes a terminal portion 1 1 and a contact portion 19 (for clarity, only a pair of conductive terminals are illustrated herein). The contact portion 19 is composed of a first sub-portion 13 and a second sub-portion 15. The end portion 1 1 of the conductive terminal extends vertically through the side wall 17 and the portion of the conductive end portion is disposed along the upper portion of the lower portion of the end portion of the second portion of the terminal. Alternatively, the end may extend directly downward so that the bottom (not shown) extends vertically. The end portion is in principle affixed to its respective P C B by, for example, soldering. In this particular embodiment, the first sub-portion 13 can be considered to originate from the beginning of the transmission extending vertically upward along the height of the side wall 17. The second subsection can be considered starting from where the contact portion 19 is no longer embedded in the side wall 17. • It should be emphasized that the end portion 1 1 and the contact portion 19 are a component. Fig. 2A shows the connector in the manufacturing process just after the guide terminal has been inserted into the interior of the housing. Details of the manufacturing process are described in Figures 5A and 5B below. In the manufacture of a female electrical connector in accordance with the present invention, the sub-portion 15 is bent into the slot to define a substantially U-shaped flexure spring 12 by the first and second sub-portions 15. The bending and thus the definition of the U-shaped flexure spring 12 on the body is achieved in two steps. The first is to bend the second sub-portion 15 by about 90 degrees so that it is at least parallel to the bottom of the slot, as shown in Figure 2B. Q It should be noted that in this particular embodiment and subsequent embodiments, the conductive terminations are typically beveled or rounded at the portions that are subject to bending, as is not explicitly shown in the accompanying drawings. The second step involves bending the second sub-portion 1 in the direction indicated by the arrow. It is bent another 90 degrees, as shown in Figure 1B, to complete the U-shape. However, due to the nature of the flexural spring, the second sub- Portions are typically not in contact with wall 17. Instead, it bends outward at an angle theta (Θ) and the groove 9 is fixed in place. As shown in Fig. 1C, by the first example, the second method is passed through the example, and the second step is substantially the same. The side forms one of the U-shaped arms by a portion 16 200818612 portion 13 3, and the second sub-port 15 forms the other arm. The intermediate portion of the U-shape may be defined by a portion of the first sub-portion 13, a second sub-portion 15, or a combination thereof, wherein the second sub-portion 15 terminates at a free end, as described above, The free end is received in slot 9 and 3A-3C illustrates a method of fabrication of an exemplary embodiment of a male interconnector in accordance with the present invention. The male connector includes an insulative mating portion having a top surface 27 and at least two mating surfaces 28. The mating surfaces 28 of the mating portion are adapted for mating with the slots of the complementary electrical connector (e.g., the electrical connector as shown in Figure 2). As in the female connector, the male connector also includes a plurality of conductive terminals. Similarly, each of the plurality of conductive terminals of the matching portion includes an end portion 2 1 and a contact portion 2 1 extending outwardly from the top surface region for attachment to a circuit board. The contact portion 2 9 has a first sub-portion 2 3 and a second sub-portion 25. The first sub-portion 2 3 is located between the end portion 21 and the first sub-portion 25. As in the female connector of Fig. 2, the contact portion 29 and the end portion 2 1 of the conductive terminal are integrally formed as a single member. The first sub-portion 2 3 is at least substantially perpendicularly contacting and extending away from the top portion along the height of the mating surfaces 28 in a first direction (downward, toward the lower end of the mating portion). The formation of the complementary electrical connector of the female connector of Figure 2 is accomplished by a two-step operation of the second sub-portion 25, wherein the second sub-portion is curved in a recessed manner. In a first step, the second sub-portion 25 is bent about 90 degrees (as indicated by the arrow of 2008 200818612) to laterally contact the mating surfaces 28. Section 3B illustrates the second sub-portion 25 that is generally parallel to the top surface of the mating portion (i.e., substantially perpendicular to the first sub-portion 23). In a second step, the second sub-portion 25 is again bent by about 90 degrees to form a substantially U-shaped flexure spring. Similar to the flexure spring of the female connector of Fig. 2, the second sub-portion 25 is also not attached to the mating surface 28, but extends outwardly by an angle phi (Φ) as shown. The U-shaped flexure spring is defined by the first and second sub-portions. As shown in Fig. 3C, one arm of the U-shape is formed by the first sub-portion 2 3, and the other arm is formed by the second sub-portion 25. The intermediate portion of the U-shape 22 can be defined by a portion of the first sub-portion 23, a portion of the second sub-portion 25, or any combination thereof, wherein the second sub-portion 25 terminates at a free end. 4A-4B illustrate one of the male and female interconnectors of one of the exemplary embodiments of Figures 2 and 3. Typically, the end portions 11 and 21 of the respective electrical connectors are soldered to the PCB. During the soldering process, the solder tends to crawl along the end portions and, if permitted, climb into the housing and climb up to the contact portions 19 and 29. In the present invention, the solder creep is prevented by the housing (side wall 17 and matching surfaces 2 7 and 2 8 ) of the respective electrical connectors due to the use of the insert soldering method. Once the complementary electrical connectors are attached to their respective PCBs, they can be matched together to electrically connect the two PCBs together. Simply insert the male electrical connector (matching portion) 3 3 into the slot of the female electrical connector 31 to effect a match, as shown in Figure 4A. To ensure a fixed fit, the end walls 3 of the female connector can include a locking mechanism. The locking mechanism 18 200818612 can have a simple bottom cut that is designed to receive the male connector and secure it in place. Essentially, this will result in a snap fit between the male and female connectors. In addition to the snap-fit arrangement described above, an additional means of securing the male and female connectors together is provided by opposing spring forces. A spring force is applied to the second sub-portion 25 of the male connector by the second sub-portion 15 of the contact portion and vice versa. Therefore, the second sub-portion 15 and the second sub-portion 25 are pressed toward each other to enhance the connectivity and to secure the mating of the male and female connectors. Once firmly matched 35, the second sub-portions 15 and 25 of the respective electrical connectors are physically in contact with each other (and thus in electrical contact). In an alternative embodiment, it is also possible that the end portion 21 of the male connector contacts the intermediate portion 12 of the U-shaped flexure spring of the female connector to establish two contact points to further improve any of the Electrical connectivity. Fig. 5A shows an exemplary embodiment of a casing, and Fig. 5B shows the casing of the exemplary embodiment of Fig. 1. In a particular embodiment of the housing, as shown in Figure 5A, due to the insert welding process, the housing can include a plurality of openings 43 in which the first sub-portion 13 is embedded. In addition, the housing may also include a plurality of recesses 4 1 along the length of the slot to accommodate the second sub-portion 15 when it is bent into the slot. Once bent into the slot, the free end of the second sub-portion will be engaged by a slot 44 extending along the length of the slot and abut any one of the side walls 17. The housing shown in Figure 5B is substantially identical to the housing of Figure 5A except that the bottom portion of the slot formed by the side walls 17 and the end wall 3 19 Ο Ο 200818612 49 includes a plurality of spaces The cavity 48, rather than the one shown in Fig. 5, is adapted to engage the free end of the second sub-portion of the conductive terminal when the conductive terminal is bent as described above. Figure 6 shows a current carrying strip having a plurality of conductive terminals. The guide terminal is formed by stamping a metal sheet. Accordingly, each of the conductive terminals of the insert molding method is formed to have an end portion 47, and the portion is composed of a first sub-portion 46 and a second sub-portion 45. The various parts and sub-portions of the terminal are formed as one integral component as shown in Figure 6 and can be symmetrically mounted to any of the current-carrying strips 48. Generally speaking, before the insert molding method, the conductive terminals The shape is generally L-shaped. The current carrying strips 48 are used to position the conductive terminals such that when a suitable mold assembly having an upper mold assembly and a lower mold assembly is utilized, a case is formed around the conductive terminals in the case of the female electrical connector. The embodiment of Figure 2 is shown in the exemplary embodiment. As previously described, the housing defines a pair of side walls 177, each side wall being defined by a pair of miscellaneous ends at opposite ends thereof to form a slot having a bottom portion 49. A seventh embodiment of the present invention shows a top view of an exemplary embodiment of the present invention and a cross-sectional view of a surrounding wire Υ-Υ. Figure 6 is similar to: The figure, except that it includes the insertion molding end of the casing during production, as described above. In the sixth embodiment, the housing is formed by the side wall end walls 59, which define the slot and the slot along the length of the slot. In this exemplary embodiment, the slot 58 is defined A bottom portion between the respective side walls 52. I. Before each slot is transmitted, the contact is conducted on a single J. The upper one is as in one, such as the body S wall 3, the fifth embodiment, the fifth end 52 and 58 ° 54 and 20 200818612 each of the conductive terminals has an end portion 51 and a connecting portion, the end portion 5 1 The contact portion (defined by the first and second sub-portions 5 3 and 5 5) extends generally perpendicularly to the side wall 52 and extends perpendicularly outwardly from the housing along the height of the respective side wall 52.
