[專利文獻1]日本特開2001-143801號公報 [Patent Document 1] Japanese Patent Laid-Open Publication No. 2001-143801

(發明概要) (Summary of the invention)

在上述專利文獻1中，將連接器之端子的接觸部形成為凹狀，將對方連接器之端子的對應接觸部形成為突部，但是在不考慮製造工程而只是著眼在作為完成品之連接器的形狀之情況下，也考量將上述接觸部的形狀與對應接觸部的形狀相反，將連接器之端子的接觸部形成為突狀，將對方連接器之端子的對應接觸部形成為凹狀或平坦面。 In the above-mentioned Patent Document 1, the contact portion of the terminal of the connector is formed in a concave shape, and the corresponding contact portion of the terminal of the counterpart connector is formed as a projection. However, the connection as a finished product is focused on regardless of the manufacturing process. In the case of the shape of the device, the shape of the contact portion is opposite to the shape of the corresponding contact portion, and the contact portion of the terminal of the connector is formed in a protruding shape, and the corresponding contact portion of the terminal of the counterpart connector is formed into a concave shape. Or flat surface.

但是，當考量連接器的製造時，即使欲將上述端子的接觸部形成為朝向接受空間突出之突部，並且利用該突出量進行壓接而易於彈性接觸，但是如後述所示，習知係因為存在有以形成上述接受空間所用之模型形狀為起因的問題，而無法使上述突部突出。 However, when the manufacture of the connector is considered, even if the contact portion of the terminal is to be formed as a projection that protrudes toward the receiving space, and the pressure is applied by the protruding amount, the elastic contact is easy, but as will be described later, the conventional system is used. Since there is a problem that the shape of the model used to form the above-mentioned receiving space is caused, the above-mentioned protrusion cannot be protruded.

例如，當考量將2個側壁間的接受空間形成為朝上方開口的情況下(將上述專利文獻1的連接器上下翻轉之姿 勢的情況)時，在一體成形時形成接受空間所用之模型，針對其插拔方向，由於上述側壁的存在造成阻礙而無法從側方進行配置，因此只能從上方(接受空間的開口側)進行配置。在從上方配置模型的情況下，該模型係在與側壁對向的面，在端子配列方向之與端子突部對應的位置，朝向上述側壁開放形成從三方包圍該突部之溝部。再者，該溝部係在從上方配置模型時以模型不會干涉上述突部的方式，在下方也必須開放形成。 For example, when it is considered that the receiving space between the two side walls is formed to open upward (the connector of Patent Document 1 is turned upside down) In the case of the force, the model for forming the receiving space is formed at the time of integral molding, and since the insertion and removal directions are hindered by the presence of the side wall and cannot be arranged from the side, it is only possible from the upper side (the opening side of the receiving space) Configure it. When the model is placed from above, the model is opened to the side wall at a position corresponding to the terminal protrusion in the terminal arrangement direction on the surface facing the side wall, and a groove portion that surrounds the protrusion from three sides is formed. Further, the groove portion is formed so as to prevent the model from interfering with the protrusion when the model is placed from above, and must be opened below.

如此一來當模型的溝部在下方也開放時，在該模型的配置後、樹脂的填充前之狀態中，該溝部係與該溝部下方的空間，也就是應該形成底壁的空間連通。因此在模型的配置後朝模型內填充樹脂時，會從該溝部的開放下端使樹脂從下方流入到該溝部內。 In this way, when the groove portion of the mold is also opened downward, the groove portion communicates with the space below the groove portion, that is, the space where the bottom wall should be formed, after the arrangement of the mold and before the filling of the resin. Therefore, when the resin is filled into the mold after the arrangement of the mold, the resin flows into the groove from the lower side from the open lower end of the groove portion.

該結果為儘管本來在突部的下方中應該在與底壁之間形成樹脂不存在的空間，但是如上述所示，因為樹脂流入到上述溝部內，因此沒有形成上述空間而且上述突部的頂部係與該流入的樹脂成為同一面而沒有突出。在如此所製成的連接器中，因為上述突出部係沒有突出量、或者失去作為突出部的機能，因此在對方端子的對應接觸部為平坦面的情況下，上述端子的突部係無法與該對應接觸部進行壓接接觸，又，在該對應接觸部為凹部的情況下，該端子的突部係除了無法與該對應接觸部進行壓接接觸之外，而且無法進行藉由朝該凹部的***之與對應接觸部在上下方向的卡止。 As a result, although a space which does not exist in the resin between the bottom wall and the bottom wall is originally formed, as described above, since the resin flows into the groove portion, the space is not formed and the top of the protrusion is formed. It is flush with the inflowing resin without protruding. In the connector thus produced, since the protruding portion has no protruding amount or loses the function as the protruding portion, when the corresponding contact portion of the counterpart terminal is a flat surface, the protruding portion of the terminal cannot be combined with The corresponding contact portion is in pressure contact, and when the corresponding contact portion is a concave portion, the protruding portion of the terminal cannot be pressed into contact with the corresponding contact portion, and the concave portion cannot be made to face the concave portion. The insertion and the corresponding contact portion are locked in the up and down direction.

有鑑於該情況，本發明係以提供一種在將具有朝向接受空間內突出的突部之端子與殼體一體成形的狀態中，使該突部確實突出之電連接器為目的。 In view of the above circumstances, the present invention has an object of providing an electrical connector in which a protruding portion is surely protruded in a state in which a terminal having a projection protruding toward the receiving space is integrally formed with the housing.

關於本發明之電連接器，其係為從上方接受對方連接器並與該對方連接器嵌合連接之電連接器，具備：具有從底壁朝上方直立並且相互對向之至少一對直立壁的殼體；及藉由一體成形配列保持在上述一對直立壁之中至少一方直立壁的複數個端子，上述殼體係在上述一對直立壁相互對向的對向面之間形成用以接受上述對方連接器之接受空間，上述端子係具有：沿著至少一方直立壁的對向面朝上下方向延伸並保持在該直立壁而且朝向接受空間內露出之腳部；及在於上述一對直立壁的對向方向在包含與上述接受空間對應的範圍之範圍沿著上述底壁朝上述對向方向延伸之基部。 The electrical connector according to the present invention is an electrical connector that receives the counterpart connector from above and is mated to the counterpart connector, and has at least one pair of upright walls that are upright from the bottom wall and face each other. And a plurality of terminals held in at least one of the pair of upright walls by integral molding, the casing being formed between the opposing faces of the pair of upright walls facing each other for receiving In the receiving space of the mating connector, the terminal has a leg portion extending in a vertical direction along a facing surface of at least one of the upright walls and held in the upright wall and exposed in the receiving space; and the pair of upright walls The opposing direction extends at a base portion extending in the opposing direction along the bottom wall in a range including a range corresponding to the receiving space.

對於該電連接器中，在本發明中，其特徵為：上述腳部係具有在上述對向方向朝向上述接受空間突出並且可與對方連接器之端子接觸之突部，上述基部中位於與上述接受空間對應的範圍內之部份，係在上述對向方向在包含上述突部位置的範圍使其上面朝向接受空間內露出。 In the present invention, in the present invention, the leg portion has a projection that protrudes toward the receiving space in the opposing direction and is in contact with a terminal of the counterpart connector, and the base portion is located in the base portion The portion in the range corresponding to the receiving space is such that the opposing direction is exposed in the receiving space in a range including the position of the protruding portion.

在用以製造關於本發明之電連接器之複數個模型之中，為了形成接受空間而從上方進行配置的模型中，與端子突部對應的部份係形成為朝上下方向延伸之溝部，該溝部 係以不會干涉該突部的方式朝向下方開放形成。在本發明中，朝直立壁的對向方向延伸之端子基部中，位於與接受空間對應的範圍內之部份係在上述對向方向在包含上述突部位置的範圍使其上面朝向接受空間內露出。因此，當從上方將該模型提供到直至使上述模型的下面抵接上述端子的基部的上面時，利用上述基部塞住上述溝部的下端。該結果為在一體成形時，因為利用上述基部阻止樹脂從上述模型的開放下端朝溝部內流入的情形，在一體成形後，在上述突部的下方確保根據樹脂不存在的空間而使該突部確實突出。 In a plurality of models for manufacturing the electrical connector according to the present invention, in a model that is disposed from above in order to form a receiving space, a portion corresponding to the terminal protrusion is formed as a groove extending in the up-and-down direction, and Ditch It is formed to open downward so as not to interfere with the protrusion. In the present invention, a portion of the terminal base extending in the opposing direction of the upright wall in a range corresponding to the receiving space is formed in the opposing direction in a range including the position of the protrusion so as to face the receiving space. Exposed. Therefore, when the mold is supplied from above until the lower surface of the base is abutted against the base of the terminal, the lower end of the groove is closed by the base. As a result, when the integral portion is formed, the resin is prevented from flowing into the groove portion from the open lower end of the mold by the base portion, and after the integral molding, the protrusion is secured under the protrusion portion depending on the space where the resin does not exist. It is really outstanding.

端子的腳部之下端係與基部接續或是與該基部的上面抵接為佳。當端子的腳部下端與基部接續或是與該基部的上面抵接時，因為在兩者之間沒有形成間隙，因此在端子與殼體的一體成形中，也可以阻止樹脂從直立壁側的開口朝上述模型的溝部流入。 Preferably, the lower end of the leg of the terminal is connected to the base or abuts against the upper surface of the base. When the lower end of the leg portion of the terminal is connected to the base portion or abuts against the upper surface of the base portion, since no gap is formed between the two, the resin can be prevented from the upright wall side in the integral molding of the terminal and the housing. The opening flows into the groove of the above model.

如以上所示，在本發明中，於一體成形時因為利用端子的基部塞住形成接受空間所用之模型的溝部下端，因此不會發生來自下方的樹脂朝該溝部內流入之不合宜情形，在端子的突部下方確保空間而使突部確實突出。因此，在連接器嵌合狀態，發揮突部本來的機能，使該突部與對方端子的對應接觸部充分壓接予以接觸、或者使該突部與對方連接器的凹狀接觸部在上下方向卡止而可以防止連接器 的脫落。 As described above, in the present invention, since the lower end of the groove portion forming the mold for receiving the space is closed by the base of the terminal during the integral molding, the inflow of the resin from the lower portion into the groove portion does not occur, and The space below the protrusion of the terminal ensures space and the protrusion does protrude. Therefore, in the state in which the connector is fitted, the original function of the projection is exerted, and the corresponding contact portion of the projection and the counterpart terminal is sufficiently pressure-contacted, or the concave contact portion of the projection and the counterpart connector is vertically moved. Locking prevents connector Fall off.

[連接器1的製造] [Manufacture of Connector 1]

連接器1係利用以下的要領進行製造。首先，利用從上方、下方及側方配置的模型(未圖示)保持端子20及固定模具30。其中，將從上方、下方及側方配置的模型各自為「上側模型」、「下側模型」及「側方模型」。上述上側模型係具有符合殼體10之接受空間16(外側接受空間16A及內側接受空間16B)的形狀之突條部份，形成該接受空間16。又，下側模型係具有適合殼體10的收容凹部11A、11B的形狀之突條部份，形成上述收納凹部11A、11B。再者，在利用上述上側模型、下側模型、及側方模型保持端子20及固定模具30的狀態下，藉由在此等模型之間填充樹脂，使端子20及固定模具30與殼體10一體模組成形而完成連接器1。 The connector 1 is manufactured by the following methods. First, the terminal 20 and the fixed mold 30 are held by a mold (not shown) arranged from the upper side, the lower side, and the side. Among them, the models arranged from the top, the bottom, and the side are the "upper model", the "lower model", and the "side model". The upper model has a ridge portion that conforms to the shape of the receiving space 16 of the casing 10 (the outer receiving space 16A and the inner receiving space 16B), and the receiving space 16 is formed. Further, the lower mold has a protruding portion suitable for the shape of the housing recesses 11A and 11B of the casing 10, and the housing recesses 11A and 11B are formed. Further, in a state in which the terminal 20 and the fixed mold 30 are held by the upper side model, the lower side model, and the side mold, the terminal 20 and the fixed mold 30 and the casing 10 are filled with resin between the models. The integrated module is formed to complete the connector 1.

上述上側模型之在與突壁部13對向的面，在端子配 列方向之與端子20的鎖定突部23B-1對應的位置，從三方包圍該鎖定突部23B-1並朝上下方向延伸的溝部係朝向上述突壁部13開放形成。再者該溝部係在下方也予以開放，在從上方配置上述上側模型時使該上側模型不會干涉到上述鎖定突部23B-1。 The surface of the upper side model facing the protruding wall portion 13 is provided at the terminal At a position corresponding to the locking projection 23B-1 of the terminal 20 in the column direction, a groove portion that surrounds the locking projection 23B-1 in three directions and extends in the vertical direction is formed to open toward the protruding wall portion 13. Further, the groove portion is also opened downward, and when the upper mold is placed from above, the upper mold does not interfere with the lock projection 23B-1.

在本實施形態中，如已闡述所示，端子20的基部22中，在上述短邊方向在包含第二外側腳部23B的鎖定突部23B-1位置之範圍，使其上面朝該外側接受空間16A內露出。因此，當從上方將該上側模型提供到直至上側模型的下面與上述基部22的上面抵接的位置時，利用上述端子20的基部22塞住該上側模型之溝部的下端。該結果為在一體成形時，因為利用上述基部22阻止樹脂從該上側模型的開放下端流入到溝部內的情況，因此在一體成形後，在鎖定突部23B-1的下方確保根據樹脂不存在的空間。 In the present embodiment, as described above, the base portion 22 of the terminal 20 receives the position of the locking projection 23B-1 including the second outer leg portion 23B in the short-side direction, and receives the upper surface toward the outer side. The space 16A is exposed. Therefore, when the upper side model is supplied from above until the lower surface of the upper mold abuts against the upper surface of the base portion 22, the lower end of the groove portion of the upper mold is closed by the base portion 22 of the terminal 20. As a result, in the integral molding, since the resin is prevented from flowing into the groove portion from the open lower end of the upper mold by the base portion 22, after the integral molding, the resin is not present under the locking projection 23B-1. space.

又，在本實施形態中，如第3圖所示，因為上述第二外側腳部23B的下端與上述基部22的上面抵接而在兩者之間沒有形成間隙，因此在一體成形時，也不會有樹脂從上述突壁部13側流入上側模型的溝部之情形。 Further, in the present embodiment, as shown in Fig. 3, since the lower end of the second outer leg portion 23B abuts against the upper surface of the base portion 22, a gap is not formed therebetween, so that when integrally formed, There is no case where the resin flows into the groove portion of the upper mold from the side of the protruding portion 13 as described above.

如此一來，藉由確實防止朝上側模型的溝部內之樹脂流入而在上述鎖定突部23B-1的下方確保上述空間，使該鎖定突部23B-1確實突出。因此，在連接器嵌合狀態中，發揮鎖定突部23B-1之本來的機能，將該鎖定突部23B-1與後述之對方端子50的被鎖定凹部51A-1在上下方向卡止而可以防止連接器的脫落。 In this way, by reliably preventing the resin from flowing into the groove portion of the upper mold, the space is secured below the lock projection 23B-1, and the lock projection 23B-1 is surely protruded. Therefore, in the connector fitting state, the original function of the locking projection 23B-1 is exhibited, and the locking projection 23B-1 and the locked recess 51A-1 of the counterpart terminal 50, which will be described later, are locked in the vertical direction.

上述基部52係利用一體模組成形而保持在殼體40的上壁41。該基部52係連結第一U字狀部51的對方第一內側腳部51A與第二U字狀部53的對方第二內側腳部53A的上端。基部52係在上述短邊方向在包含與對方外側接受空間46A對應的範圍之範圍呈直狀延伸。 The base portion 52 is formed by the integral module and held by the upper wall 41 of the casing 40. The base portion 52 connects the first inner leg portion 51A of the first U-shaped portion 51 and the upper end of the other second inner leg portion 53A of the second U-shaped portion 53. The base portion 52 extends straight in a range including the range corresponding to the counterpart outer receiving space 46A in the short side direction.

如第3圖所示，上述基部52之下面(在2圖中為上面)係位於與上壁41的下面大致相同水平，在與上述對方外側接受空間46A對應的範圍朝該對方外側接受空間46A內露出。使下面朝該對方外側接受空間46A內露出的部份係在上述短邊方向位於包含對方第二外側腳部53B的被鎖定突部53B-1位置之範圍。又，第二U字狀部53之對 方第二外側腳部53B的上端係與上述基部22之露出的下面抵接。 As shown in Fig. 3, the lower surface of the base portion 52 (the upper surface in Fig. 2) is located at substantially the same level as the lower surface of the upper wall 41, and receives the space 46A toward the outside of the other side in a range corresponding to the outer side receiving space 46A.

Moreover, the pair of the second U-shaped portions 53 The upper end of the square second outer leg portion 53B abuts against the exposed lower surface of the base portion 22.

固定模具60係將帶狀的金屬板條片朝板厚方向彎曲製作，在對方連接器2之平面形狀中的四個角落利用一體模組成形而保持在端壁45。如第2圖所示，該固定模具60係具有：與對方端子50之連接部54相同形狀的固定部61，並且與對方端子50相輔相成藉由將該固定部61焊接在電路基板上，對於朝電路基板之連接器1的固定強度提升有所幫助。 The fixed mold 60 is formed by bending a strip-shaped metal strip piece in the thickness direction, and is formed by the integral module in the four corners of the planar shape of the mating connector 2 and held by the end wall 45. As shown in FIG. 2, the fixed mold 60 has a fixing portion 61 having the same shape as the connecting portion 54 of the counterpart terminal 50, and is complementary to the counterpart terminal 50 by soldering the fixing portion 61 to the circuit board. The fixing strength of the connector 1 of the circuit board is helpful.

[對方連接器2的製造] [Manufacture of the other connector 2]

對方連接器2係藉由將第2圖所示之對方接受空間46朝上方開口的姿勢予以製作，與上述連接器1相同，在利用上側模型、下側模型、及側方模型保持對方端子50及固定模具60的狀態下，將樹脂填充到模型之間，藉由將該對方端子50與固定模具60與殼體40一體模組成形予以製造。 The counterpart connector 2 is formed by opening the other side receiving space 46 shown in FIG. 2 upward, and similarly to the above-described connector 1, the counterpart terminal 50 is held by the upper model, the lower model, and the side model. In the state in which the mold 60 is fixed, the resin is filled between the molds, and the counterpart terminal 50 and the fixed mold 60 are integrally molded with the casing 40 to be manufactured.

又如已闡述所示，對方端子50的基部52係在殼體40的短邊方向在包含對方第二外側腳部53B的被鎖定突部53B-1位置的範圍，使第2圖的上面(在第3圖中為下面)位於與上壁41的上面(在第3圖中為下面)大致相同水平並且朝該對方外側接受空間46A露出，而且上述對方第二外側腳部53B的下端(在第3圖中為上端)係與上述基部52的上面(在第3圖為下面)抵接。因此，在一體成形 時，與已闡述之連接器1相同，防止樹脂流入上側模型的溝部，而使被鎖定突部53B-1確實突出。 Further, as already explained, the base portion 52 of the counterpart terminal 50 is in the range of the position of the locked projection 53B-1 including the second outer leg portion 53B of the other side in the short-side direction of the casing 40, so that the upper surface of FIG. 2 is The lower surface in Fig. 3 is located at substantially the same level as the upper surface of the upper wall 41 (lower in Fig. 3) and is exposed toward the outer side receiving space 46A, and the lower end of the second outer leg portion 53B of the other side (at The upper end in Fig. 3 is in contact with the upper surface of the base portion 52 (lower in Fig. 3). Therefore, in one piece At the same time as the connector 1 described above, the resin is prevented from flowing into the groove portion of the upper mold, and the locked projection 53B-1 is surely protruded.

[連接器嵌合動作] [Connector fitting action]

以下，針對連接器1與對方連接器2的嵌合動作進行說明。首先，將連接器1的端子20以及固定模具30焊接在電路基板，而且將對方連接器2的端子50及固定模具60焊接在其他電路基板。其次，如第3圖所示，將連接器1成為接受空間16朝上方開口的姿勢，而且將對方連接器2成為對方接受空間46朝下方開口的姿勢並提供到該連接器1的上方位置。 Hereinafter, the fitting operation of the connector 1 and the counterpart connector 2 will be described. First, the terminal 20 of the connector 1 and the fixed mold 30 are welded to the circuit board, and the terminal 50 of the counterpart connector 2 and the fixed mold 60 are welded to other circuit boards. Next, as shown in FIG. 3, the connector 1 is in a posture in which the receiving space 16 is opened upward, and the counterpart connector 2 is placed in a posture in which the opponent receiving space 46 is opened downward and is provided above the connector 1.

再者，如第3圖之箭頭方向所示，將對方連接器2朝下方移動，從上方各自將對方連接器2的側壁44及突壁部43嵌入到連接器1的外側接受空間16A及內側接受空間16B內。又與此同時，從下方各自將連接器1的突壁部13及中央壁部12嵌入到對方連接器2的對方外側接受空間46A及對方內側接受空間46B內。 Further, as shown by the direction of the arrow in Fig. 3, the counterpart connector 2 is moved downward, and the side wall 44 and the projecting wall portion 43 of the mating connector 2 are fitted into the outer receiving space 16A and the inside of the connector 1 from above. Accepted space 16B. At the same time, the protruding wall portion 13 and the central wall portion 12 of the connector 1 are fitted into the outer side receiving space 46A and the inner side receiving space 46B of the counterpart connector 2 from below.

藉由從上方將對方連接器2的側壁44嵌入到連接器1的外側接受空間16A內，對方連接器2之對方端子50的第一U字狀部51係壓開進入到連接器1之端子20的鎖定凹部21A-1與鎖定突部23B-1之間。又，藉由從上方將對方連接器2的突壁部43嵌入到連接器1的內側接受空間16B內，對方連接器2之對方端子50的第二U字狀部53係壓開進入到連接器1之端子20的鎖定凹部23A-1 與中央壁部12之間。 By fitting the side wall 44 of the counterpart connector 2 into the outer receiving space 16A of the connector 1 from above, the first U-shaped portion 51 of the counterpart terminal 50 of the counterpart connector 2 is pressed into the terminal of the connector 1. Between the locking recess 21A-1 of the 20 and the locking projection 23B-1. Further, by inserting the protruding wall portion 43 of the counterpart connector 2 into the inner receiving space 16B of the connector 1 from above, the second U-shaped portion 53 of the counterpart terminal 50 of the counterpart connector 2 is pressed into the connection. Locking recess 23A-1 of terminal 20 of device 1 Between the central wall portion 12.

又藉由從下方將連接器1的突壁部13嵌入到對方連接器2的對方外側接受空間46A內，連接器1之端子20的第二逆U字狀部23係壓開進入到對方連接器2之對方端子50的被鎖定凹部51A-1與被鎖定突部53B-1之間。 Further, by inserting the protruding wall portion 13 of the connector 1 into the external receiving space 46A of the counterpart connector 2 from below, the second reverse U-shaped portion 23 of the terminal 20 of the connector 1 is pressed into the other side. The locked recess 51A-1 of the counterpart terminal 50 of the device 2 is locked between the locked projection 53B-1.

當進一步進行連接器的嵌合動作時，使連接器1之鎖定凹部21A-1、鎖定突部23B-1及鎖定凹部23A-1與對方連接器2之被鎖定突部51B-1、被鎖定凹部51A-1及被鎖定突部53B-1在上下方向卡合。該結果為使連接器的端子電氣導通而且相互鎖定，結束連接器的嵌合連接。 When the fitting operation of the connector is further performed, the locking recess 21A-1, the locking projection 23B-1, and the locking recess 23A-1 of the connector 1 and the locked projection 51B-1 of the counterpart connector 2 are locked. The concave portion 51A-1 and the locked projection portion 53B-1 are engaged in the vertical direction. As a result, the terminals of the connector are electrically connected and locked to each other, and the fitting connection of the connector is terminated.

如上述所示，在連接器嵌合的中途，因為對方端子50的第一U字狀部51係壓開進入到端子20的鎖定凹部21A-1與鎖定突部23B-1之間，因此在殼體10的短邊方向朝向外側的推壓力係作用在端子20的第一內側腳部21A及殼體10的側壁14，並且以該第一內側腳部21A及側壁14的下部作為支點產生力矩。 As described above, in the middle of the fitting of the connector, since the first U-shaped portion 51 of the counterpart terminal 50 is pressed into between the locking recess 21A-1 of the terminal 20 and the locking projection 23B-1, The urging force of the outer side of the casing 10 toward the outer side acts on the first inner leg portion 21A of the terminal 20 and the side wall 14 of the casing 10, and generates a moment with the lower portion of the first inner leg portion 21A and the side wall 14 as a fulcrum. .

在本實施形態中，因為從第一內側腳部21A的下端朝向上述短邊方向內側延伸之內側連接部22A係在該短邊方向位於比第一內側腳部21A更內側，因此與上述力矩反抗並在上述內側連接部22A與電路基板之焊接部份產生反抗力。因此，因為只藉由該反抗力部份就可以使作用於端子20的外側連接部24與電路基板之焊接部份的外力變小，因此可以防止該焊接部份的損傷。 In the present embodiment, the inner connecting portion 22A extending from the lower end of the first inner leg portion 21A toward the inner side in the short side direction is located inside the first inner leg portion 21A in the short side direction, and thus resists the above torque. The opposing force is generated in the welded portion of the inner connecting portion 22A and the circuit board. Therefore, since the external force acting on the welded portion of the outer connecting portion 24 of the terminal 20 and the circuit board can be made small by only the reactive force portion, damage of the welded portion can be prevented.

又在本實施形態中，各端子20與對方端子50係在3 處進行鎖定，因此在與如習知所示將端子在1處予以鎖定的情況相比，使進行鎖定處的數目變多，該點就可以使鎖定強度變大。又不能單純地只說「鎖定是只藉由鎖定處數目就可以加強」，但是因為在鎖定處之間有距離，因此對於根據產生傾斜的外力之力矩而言可以變強。因此，即使在使端子20及對方端子50的板厚尺寸變小而使連接器1及對方連接器2低背化的情況下，不會減低在連接器整體的鎖定強度，可以良好防止連接器之不經意的脫落。 Further, in the present embodiment, each of the terminals 20 and the counterpart terminal 50 is tied to 3. The locking is performed, so that the number of the locking portions is increased as compared with the case where the terminal is locked at one position as shown in the prior art, and the locking strength can be made large. It cannot be simply said that "the lock is reinforced only by the number of locks", but since there is a distance between the locks, it can be made strong with respect to the moment according to the external force that generates the inclination. Therefore, even when the thickness of the terminal 20 and the counterpart terminal 50 is reduced and the connector 1 and the counterpart connector 2 are lowered, the locking strength of the connector as a whole is not reduced, and the connector can be prevented well. Inadvertently falling off.

在本實施形態中，連接器的端子雖然是在第一內側腳部形成鎖定凹部，在第二內側腳部形成鎖定凹部，在第二外側腳部形成鎖定突部，但是因應端子基部的形狀，適當變更為在任何的腳部形成鎖定突部或鎖定凹部亦可。具體而言，在殼體的短邊方向在端子基部的上面朝接受空間露出的範圍中，因為於一體成形時沒有使樹脂流入上側模型的溝部內之虞，因此形成鎖定突部及鎖定凹部的任一個皆可。一方面，在上述基部的上面沒有露出的範圍內，因為於一體成形時無法防止樹脂從下端開口朝上側模型的溝部內流入，因此不能形成鎖定突部，只能形成鎖定凹部。 In the present embodiment, the terminal of the connector has a locking concave portion formed in the first inner leg portion, a locking concave portion is formed in the second inner leg portion, and a locking projection portion is formed in the second outer leg portion. However, depending on the shape of the terminal base portion, It is also possible to appropriately change the locking projection or the locking recess in any of the legs. Specifically, in the range in which the upper side of the terminal base portion is exposed to the receiving space in the short-side direction of the casing, since the resin does not flow into the groove portion of the upper mold at the time of integral molding, the locking projection and the locking concave portion are formed. Any one can be. On the other hand, in the range where the upper surface of the base portion is not exposed, since the resin cannot be prevented from flowing into the groove portion of the upper mold from the lower end opening during the integral molding, the locking projection cannot be formed, and only the locking concave portion can be formed.

又若是在下方使基部的上面露出的話，在上述第一內側腳部、第二內側腳部、及第二外側腳部的所有腳部形成鎖定突部亦可，無論是否在下方使基部的上面露出，也可以在上述所有腳部形成鎖定凹部。再者，在對方連接器的對方端子中，與連接器之端子各腳部的鎖定突部及鎖定凹部對應而形成被鎖定凹部及被鎖定突部。 Further, if the upper surface of the base portion is exposed below, the locking projections may be formed on all of the leg portions of the first inner leg portion, the second inner leg portion, and the second outer leg portion, regardless of whether the base portion is below or below. Exposed, a locking recess may be formed in all of the above-mentioned legs. Further, in the counterpart terminal of the counterpart connector, the locked projection and the locked projection are formed corresponding to the locking projection and the locking recess of each leg of the connector terminal.

又在本實施形態中，雖然是在上述第一內側腳部、第二內側腳部及第二外側腳部之3個腳部全都形成鎖定突部或鎖定凹部，但是取而代之，以在3個腳部之中的2個腳部形成鎖定突部或鎖定凹部，並且在1個腳部不形成鎖定突部或鎖定凹部而成為平坦的接觸部亦可。 Further, in the present embodiment, the locking projections or the locking recesses are formed in all of the three leg portions of the first inner leg portion, the second inner leg portion, and the second outer leg portion, but instead are replaced by three legs. The two leg portions of the portion may form a locking projection or a locking recess, and may form a flat contact portion without forming a locking projection or a locking recess in one leg.

在本實施形態中，端子的鎖定突部或鎖定凹部雖然是利用比端子的寛幅尺寸更小的尺寸予以形成，但是取而代之，例如也可以藉由將端子朝板厚方向彎曲，涵蓋端子的整個寬幅方向形成該鎖定突部及鎖定凹部端子。 In the present embodiment, the locking projection or the locking recess of the terminal is formed by a size smaller than the width of the terminal. Alternatively, for example, the terminal may be bent in the thickness direction to cover the entire terminal. The locking projection and the locking recess terminal are formed in the wide direction.

又，在本實施形態中，端子之第一逆U字狀部的第一內側腳部的外面、第二逆U字狀部的外面、及基部的上面雖然各自與側壁、突壁部及底壁成為同一水平的面予以露出，但是取而代之，位於比側壁、突壁部及底壁更突出的水平亦可。 Further, in the present embodiment, the outer surface of the first inner leg portion of the first reverse U-shaped portion of the terminal, the outer surface of the second reverse U-shaped portion, and the upper surface of the base portion are respectively formed with the side wall, the protruding wall portion, and the bottom portion. The wall is exposed at the same level, but instead it may be located at a level that is more prominent than the side wall, the protruding wall portion, and the bottom wall.

在本實施形態中，雖然使端子的基部形成為連結第一逆U字狀部的第一內側腳部及第二逆U字狀部的內側腳部之下端，但是取而代之，基部係形成為連結第一逆U字狀部的第一內側腳端部下端及第二逆U字狀部的第二外側腳部下端亦可。又在該情況下，在各端子設置3個以上的逆U字狀部，而且在殼體設置保持各逆U字狀部的側壁或突壁部，在相互鄰接的逆U字狀部與本實施形態所說明者相同形成鎖定突部及鎖定凹部亦可。藉此，因為鎖定處數目進一步變多，以該點就可以增大鎖定強度。 In the present embodiment, the base portion of the terminal is formed to connect the first inner leg portion of the first reverse U-shaped portion and the lower end of the inner leg portion of the second reverse U-shaped portion, but the base portion is formed to be connected. The lower end of the first inner leg end portion of the first reverse U-shaped portion and the lower end of the second outer leg portion of the second reverse U-shaped portion may also be used. In this case, three or more reverse U-shaped portions are provided in each of the terminals, and the side wall or the protruding wall portion of each of the reverse U-shaped portions is provided in the casing, and the opposite U-shaped portions and the adjacent portions are adjacent to each other. In the embodiment, the locking projection and the locking recess may be formed in the same manner. Thereby, since the number of locks is further increased, the lock strength can be increased at this point.

如以上所述之變形例係對於對方連接器也適用。 The modification as described above is also applicable to the counterpart connector.

在本實施形態中，雖然是將端子之內側焊接部及外側焊接部兩者作為與電路基板之對應電路部的電氣連接所用之連接部，但是取而代之，將任何一方作為連接部，並且將另一方對於電路基板的電氣連接為不連接，而是為了對該電路基板之連接器的固定而形成為被焊接之固定部亦可。 In the present embodiment, the inner soldering portion and the outer soldering portion of the terminal are used as a connecting portion for electrical connection with the corresponding circuit portion of the circuit board. However, either one is used as the connecting portion and the other is used. The electrical connection of the circuit board may not be connected, but may be formed as a fixed portion to be soldered in order to fix the connector of the circuit board.

又，在本實施形態中，對方連接器的殼體係具有側壁及突壁部，並且該側壁為保持對方端子的第一U字狀部，突壁部為保持對方端子的第二U字狀部，但是取而代之，在殼體沒有設置突壁部，使對方端子的第二U字狀部沒有保持在殼體而是單獨位置亦可。 Further, in the present embodiment, the housing of the counterpart connector has a side wall and a protruding wall portion, and the side wall is a first U-shaped portion that holds the other terminal, and the protruding wall portion is a second U-shaped portion that holds the other terminal. However, instead of providing a protruding wall portion in the housing, the second U-shaped portion of the counterpart terminal may not be held in the housing but in a separate position.

又，在本實施形態中，雖然是將本發明適用在插座型的連接器之情況進行說明，但是取而代之，也可以將本發明適用在插頭型的連接器。在該情況下，對方端子之被鎖定突部及被鎖定凹部係具有作為鎖定突部及鎖定凹部的機能。 Further, in the present embodiment, the case where the present invention is applied to a socket type connector will be described. However, the present invention may be applied to a plug type connector. In this case, the locked projection and the locked recess of the counterpart terminal have a function as a locking projection and a locking recess.

在本實施形態中，對方連接器雖然是電路基板用電連接器，但是對方連接器的形態係不限於此。例如，成為對方端子與電線連接之電線用電連接器亦可。又，在本實施形態中，對方連接器係將對方端子與殼體一體成形，但是取而代之，藉由將對方端子壓入到殼體而保持在該殼體亦可。 In the present embodiment, the counterpart connector is an electrical connector for a circuit board, but the form of the counterpart connector is not limited thereto. For example, an electrical connector for a wire that is connected to a terminal and a wire can be used. Further, in the present embodiment, the counterpart connector integrally forms the counterpart terminal and the case, but instead, the counterpart terminal may be held in the case by being pressed into the case.

又，在本實施形態中，對方連接器的殼體係具有側壁及突壁部，該側壁為保持對方端子的第一U字狀部，突 壁部為保持對方端子的第二U字狀部，但是取而代之，在殼體沒有設置突壁部，使對方端子的第二U字狀部沒有保持在殼體而是單獨位置亦可。 Further, in the present embodiment, the housing of the counterpart connector has a side wall and a protruding wall portion, and the side wall is a first U-shaped portion that holds the other terminal. The wall portion is a second U-shaped portion that holds the other terminal, but instead, the protruding portion is not provided in the casing, and the second U-shaped portion of the counterpart terminal may not be held in the casing but in a separate position.

<第二實施形態> <Second embodiment>

在第一實施形態中，如第3圖所示，基部22係連結第一逆U字狀部21的第一內側腳部21A及第二逆U字狀部23的第二內側腳部23A的下端，但是在本實施形態中，利用從第一逆U字狀部的第一內側腳部下端延伸之基部與第二逆U字狀部的第二外側腳部下端之點而在構成上與第一實施形態有所不同。 In the first embodiment, as shown in FIG. 3, the base portion 22 connects the first inner leg portion 21A of the first reverse U-shaped portion 21 and the second inner leg portion 23A of the second reverse U-shaped portion 23. The lower end, but in the present embodiment, the base portion extending from the lower end of the first inner leg portion of the first reverse U-shaped portion and the lower end of the second outer leg portion of the second reverse U-shaped portion are configured in a The first embodiment is different.

第4圖係為關於本實施形態之連接器101的剖面圖，顯示在殼體110的長邊方向之端子120的位置之剖面。該連接器101係因為除了上述之相異點之外，其他構成與第一實施形態的連接器1相同，因此在與第一實施形態相同的部份係附予在第一實施形態的符號加上「100」的符號而省略說明，並且以上述相異點為中心進行說明。 Fig. 4 is a cross-sectional view showing the connector 101 of the present embodiment, showing a cross section of the position of the terminal 120 in the longitudinal direction of the casing 110. The connector 101 is the same as the connector 1 of the first embodiment except for the above-described different points. Therefore, the same components as those of the first embodiment are attached to the symbols in the first embodiment. The description of the symbol "100" is omitted, and the description will be given focusing on the above-described different points.

如第4圖所示，連接器101之端子120的基部122係從第一逆U字狀部121的第一內側腳部121A下端延伸，並且與第二逆U字狀部123的第二外側腳部123B下端連結。在本實施形態中，因為基部122與第二外側腳部123B為連續的而在兩者之間不會產生間隙，因此在與如第一實施形態所示將第二外側腳部123B的下端抵接在基部122的上面之情況相比，在一體成形時可以更確實阻止 樹脂從突壁部113側朝上側模型的溝部內流入的情形。該結果為在一體成形後，因為在上述第二外側腳部123B的鎖定突部123B-1下方確保根據樹脂不存在的空間，因此使該鎖定突部123B-1確實突出而可以發揮本來的機能。 As shown in FIG. 4, the base portion 122 of the terminal 120 of the connector 101 extends from the lower end of the first inner leg portion 121A of the first reverse U-shaped portion 121 and the second outer side of the second reverse U-shaped portion 123. The lower end of the leg portion 123B is coupled. In the present embodiment, since the base portion 122 and the second outer leg portion 123B are continuous and no gap is formed therebetween, the lower end of the second outer leg portion 123B is brought into contact with the first embodiment as shown in the first embodiment. Compared with the case of being attached to the upper surface of the base portion 122, it can be more reliably prevented when integrally formed. The resin flows from the side of the protruding portion 113 toward the groove portion of the upper model. As a result, after the integral molding, the space that does not exist according to the resin is secured under the locking projection 123B-1 of the second outer leg portion 123B. Therefore, the locking projection 123B-1 is surely protruded to exhibit the original function. .

<第三實施形態> <Third embodiment>

關於本實施形態之連接器係利用在端子之2個逆U字狀部之中位於殼體的側壁側之第一逆U字狀部的第一內側腳部形成鎖定突部、在位於殼體的突壁部側之第二逆U字狀部的第二內側腳部及第二外側腳部各自形成鎖定凹部之點，在構成上與在第一內側腳部及第二內側腳部形成鎖定凹部、在第二外側腳部形成鎖定突部之第一實施形態有所不同。又在本實施形態中，使端子基部的固定部之上面朝外側接受空間露出之點也在構成上與將固定部的上面與殼體的底壁接面並被樹脂覆蓋之第一實施形態有所不同。 In the connector of the present embodiment, the first inner leg portion of the first reverse U-shaped portion located on the side wall side of the casing among the two reverse U-shaped portions of the terminal is formed with a locking projection, and is located in the housing. The second inner leg portion and the second outer leg portion of the second reverse U-shaped portion on the protruding wall portion form a point of locking the recess portion, and form a lock on the first inner leg portion and the second inner leg portion The first embodiment in which the recessed portion forms a locking projection on the second outer leg portion is different. Further, in the present embodiment, the first embodiment in which the upper surface of the fixing portion of the terminal base portion is exposed to the outer receiving space is configured to be in contact with the upper surface of the fixing portion and the bottom wall of the casing, and is covered with a resin. Different.

第5圖為關於本實施形態之連接器201的剖面圖，顯示在殼體210的長邊方向之端子220的位置之剖面。該連接器201係因為除了上述之相異點之外，其他構成與第一實施形態的連接器1相同，因此在與第一實施形態相同的部份係附予在第一實施形態的符號加上「200」的符號而省略說明，並且以上述相異點為中心進行說明。 Fig. 5 is a cross-sectional view showing the connector 201 of the present embodiment, showing a cross section of the position of the terminal 220 in the longitudinal direction of the casing 210. The connector 201 is the same as the connector 1 of the first embodiment except for the above-described different points. Therefore, the same components as those of the first embodiment are attached to the symbols in the first embodiment. The description of the symbol "200" is omitted, and the description will be made focusing on the above-described different points.

如第5圖所示，連接器201的端子220係在端子220的第一逆U字狀部221的第一內側腳部221A形成鎖定突 部221A-1、在第二逆U字狀部223的第二內側腳部223A形成鎖定凹部223A-1、在該第二逆U字狀部223的第二外側腳部223B形成鎖定凹部223B-1。 As shown in FIG. 5, the terminal 220 of the connector 201 forms a locking protrusion at the first inner leg portion 221A of the first reverse U-shaped portion 221 of the terminal 220. The portion 221A-1 forms a locking recess 223A-1 in the second inner leg portion 223A of the second reverse U-shaped portion 223, and forms a locking recess 223B in the second outer leg portion 223B of the second inverted U-shaped portion 223. 1.

上述端子220的基部222係在殼體210的短邊方向(在第5圖為左右方向)在與外側接受空間216A對應的範圍使其上面朝向該外側接受空間216A露出。換言之，與第一實施形態不同，在上述基部222的固定部222A之上方沒有樹脂存在。因此，在上述連接器201的製造工程，當將上側模型提供到直至該上側模型的下面與上述基部222的上面抵接時，與上述鎖定突部221A-1對應，利用上述固定部222A的上面塞住形成在上側模型之溝部的下端。該結果為在一體成形時，因為利用上述固定部222A阻止樹脂從上側模型之開放下端流入到溝部內的情形，因此在一體成形後，在鎖定突部221A-1的下方確保根據樹脂不存在的空間，使該鎖定突部221A-1確實突出而可以發揮本來的機能。 The base portion 222 of the terminal 220 is exposed to the outer receiving space 216A in a range corresponding to the outer receiving space 216A in the short-side direction of the housing 210 (the left-right direction in FIG. 5). In other words, unlike the first embodiment, no resin exists above the fixing portion 222A of the base portion 222. Therefore, in the manufacturing process of the connector 201, when the upper model is supplied until the lower surface of the upper mold abuts against the upper surface of the base portion 222, the upper surface of the fixing portion 222A is used corresponding to the locking projection 221A-1. The lower end of the groove formed in the upper model is plugged. As a result, in the case of integral molding, the resin is prevented from flowing into the groove portion from the open lower end of the upper mold by the fixing portion 222A. Therefore, after the integral molding, the resin is not present under the locking projection 221A-1. In the space, the locking projection 221A-1 is surely protruded to exert its original function.

<第四實施形態> <Fourth embodiment>

在第一實施形態中，如第3圖所示，雖然在連接器1之端子20的第一內側腳部21A形成鎖定凹部21A-1，但是在本實施形態中，利用在第一內側腳部形成鎖定突部之點而與第一實施形態有所不同。又在第一實施形態中，將連接器1之端子20的基部22彎曲形成為曲柄狀，但是在本實施形態中，利用將端子的基部沿著殼體的底壁形成為 直狀之點而與第一實施形態有所不同。 In the first embodiment, as shown in Fig. 3, the locking recess 21A-1 is formed in the first inner leg portion 21A of the terminal 20 of the connector 1, but in the present embodiment, the first inner leg portion is used. The point at which the locking projection is formed is different from that of the first embodiment. Further, in the first embodiment, the base portion 22 of the terminal 20 of the connector 1 is bent into a crank shape. However, in the present embodiment, the base portion of the terminal is formed along the bottom wall of the casing. The straight point is different from the first embodiment.

第6圖係為顯示關於本實施形態之連接器301與對方連接器302之嵌合前的狀態之剖面圖，顯示在殼體長邊方向中之端子320的位置之剖面。連接器301係因為除了上述之相異點之外，其他構成與第一實施形態的連接器1相同，因此在與第一實施形態相同的部份係附予在第一實施形態的符號加上「300」的符號而省略說明，並且以上述相異點為中心進行說明。 Fig. 6 is a cross-sectional view showing a state before the connector 301 and the counterpart connector 302 of the present embodiment are fitted, and shows a cross section of the position of the terminal 320 in the longitudinal direction of the casing. The connector 301 is the same as the connector 1 of the first embodiment except for the above-described different points. Therefore, the same components as those of the first embodiment are attached to the symbols of the first embodiment. The description of the symbol "300" is omitted, and the above-described different points will be mainly described.

如第6圖所示，連接器301之端子320係在第一逆U字狀部321的第一內側腳部321A形成鎖定突部321A-1，在第二逆U字狀部323的第二外側腳部323B形成鎖定突部323B-1，以及在第二內側腳部323A形成鎖定凹部323A-1。 As shown in FIG. 6, the terminal 320 of the connector 301 forms a locking projection 321A-1 in the first inner leg portion 321A of the first reverse U-shaped portion 321, and a second projection in the second inverse U-shaped portion 323. The outer leg portion 323B forms the locking projection 323B-1, and the second inner leg portion 323A forms the locking recess 323A-1.

在本實施形態中，如第6圖所示，上述端子320的基部322係在殼體310的短邊方向(在第6圖中的左右方向)在與外側接受空間316A對應的範圍呈直狀延伸，並且使該基部322的上面朝該外側接受空間316A露出。又，基部322沒有與第一實施形態之內側連接部22A對應的連接部。即使在本實施形態中，與第一實施形態相同，在一體成形時藉由使該基部322的上面塞住模型的溝部之端部，防止朝該溝部內之樹脂的流入。該結果為使上述鎖定突部321A-1及鎖定突部323B-1在上述短邊方向朝向外側接受空間316A確實突出而可以發揮本來的機能。 In the present embodiment, as shown in Fig. 6, the base portion 322 of the terminal 320 is straight in the short-side direction of the casing 310 (the horizontal direction in Fig. 6) in a range corresponding to the outer receiving space 316A. It extends and exposes the upper surface of the base 322 toward the outer receiving space 316A. Further, the base portion 322 does not have a connection portion corresponding to the inner connecting portion 22A of the first embodiment. In the present embodiment, as in the first embodiment, the end portion of the groove portion of the mold is blocked by the upper surface of the base portion 322 at the time of integral molding, thereby preventing the inflow of the resin into the groove portion. As a result, the locking projection 321A-1 and the locking projection 323B-1 can be surely protruded toward the outer receiving space 316A in the short-side direction, and the original function can be exhibited.

又與上述連接器301嵌合連接之對方連接器302係如 第6圖所示，各自與連接器301之第一內側腳部321A的鎖定突部321A-1、第二外側腳部323B的鎖定突部323B-1、以及第二內側腳部323A的鎖定凹部323A-1對應，在對方第一外側腳部351B形成被鎖定突部351B-1、在對方第一內側腳部351A形成被鎖定凹部351A-1、以及在對方第二外側腳部353B形成被鎖定突部353B-1。 Further, the counterpart connector 302 that is mated to the connector 301 is like As shown in Fig. 6, the locking projections 321A-1 of the first inner leg portion 321A of the connector 301, the locking projections 323B-1 of the second outer leg portion 323B, and the locking recesses of the second inner leg portion 323A are shown. 323A-1 corresponds to the formation of the locked projection 351B-1 in the first outer leg portion 351B, the locking recess 351A-1 in the first inner leg portion 351A, and the locking on the second outer leg 353B. Projection 353B-1.

The connector and the counterpart connector of the present embodiment are basically the same as the basic configuration of the counterpart connector 2 and the connector 1 of the first embodiment. In the first embodiment, the locking projections 51B-1 and 53B-1 and the locking recess 51A-1 are formed in the counterpart terminal 50 of the counterpart connector 2, and the locking projection 23B-1 and the locking are formed at the terminal 20 of the connector 1. The recesses 21A-1 and 23A-1 are different from the first embodiment in that only the locking projections are formed at the terminals of the connector, and only the locking recesses are formed at the terminals of the counterpart connector. In the present embodiment, the same components as the counterpart connector 2 and the connector 1 of the first embodiment are attached with symbols of "400" to the symbols of the counterpart connector 2 and the connector 1, and the description thereof is omitted. The locking projection and the locking recess will be described as a center.

第7圖係為顯示關於本實施形態之連接器402與對方連接器401之嵌合前的狀態之剖面圖，顯示在殼體長邊方向中之端子450的位置之剖面。如第7圖所示，關於本實 施形態之連接器402係在端子450之第一U字狀部451的第一內側腳部451A形成鎖定突部451A-1、在該第一U字狀部451的第一外側腳部451B形成鎖定突部451B-1、在第二U字狀部453的第二外側腳部453B形成鎖定突部453B-1。 Fig. 7 is a cross-sectional view showing a state before the connector 402 of the present embodiment and the counterpart connector 401 are fitted, and shows a cross section of the position of the terminal 450 in the longitudinal direction of the casing. As shown in Figure 7, about this The connector 402 of the embodiment forms a locking projection 451A-1 at the first inner leg portion 451A of the first U-shaped portion 451 of the terminal 450, and forms a first outer leg portion 451B of the first U-shaped portion 451. The locking projection 451B-1 and the second outer leg portion 453B of the second U-shaped portion 453 form a locking projection 453B-1.

與上述連接器402嵌合連接之對方連接器401係如第7圖所示，各自與連接器402的鎖定突部451A-1、451B-1、453B-1對應，在對方第二外側腳部423B形成被鎖定凹部423B-1、在對方端子420的對方第一內側腳部421A形成被鎖定凹部421A-1、在對方第二內側腳部423A形成被鎖定凹部423A-1。 The counterpart connectors 401 that are mated to and connected to the connector 402 are respectively corresponding to the locking projections 451A-1, 451B-1, and 453B-1 of the connector 402, and are located on the second outer leg of the counterpart as shown in FIG. 423B forms the locked concave portion 423B-1, the locked first recessed portion 421A-1 is formed on the other first inner leg portion 421A of the counterpart terminal 420, and the locked recessed portion 423A-1 is formed in the other second inner leg portion 423A.

如第7圖所示，上述連接器402係因為在上述短邊方向在與外側接受空間456A對應之範圍呈直狀延伸，並且使基部452的下面朝外側接受空間446A露出，因此在一體成形時藉由使該基部452的下面塞住模型的溝部之端部，防止朝該溝部內之樹脂的流入。該結果為使上述鎖定突部451A-1及鎖定突部453B-1在殼體440的短邊方向(在第7圖為左右方向)朝向外側接受空間446A確實突出而可以發揮本來的機能。 As shown in Fig. 7, the connector 402 is linearly extended in the short-side direction in the range corresponding to the outer receiving space 456A, and the lower surface of the base portion 452 is exposed to the outer receiving space 446A. The inflow of the resin in the groove portion is prevented by blocking the lower surface of the groove portion of the mold by the lower surface of the base portion 452. As a result, the locking projection 451A-1 and the locking projection 453B-1 can be surely protruded toward the outer receiving space 446A in the short-side direction of the casing 440 (the horizontal direction in FIG. 7), and the original function can be exhibited.
