Description
本發明是關於電路基板用電連接器。The present invention relates to an electrical connector for a circuit board.
作為電連接器，已知有專利文獻1的電連接器。在專利文獻1，揭示有：大致長方體外形的殼體、在相對於電路基板成直角而互相相對向的該殼體的兩個側面排列有複數個端子的電連接器。該電連接器的端子，是具有：在殼體的側面處形成的作為凹部的收容部所收容的主體片、從該主體片的上端朝上方延伸而與電路基板連接的固定端子片、以及從該主體片的下端延伸，朝向下方凸狀彎曲而與其他電路基板彈性接觸的接觸端子片。上述固定端子片，具有上半部與下半部，上半部朝電路基板的後述端子插通孔插通，下半部與殼體的側面之間隔著一定的間隙而沿著該側面延伸。As an electrical connector, an electrical connector of Patent Document 1 is known. Patent Document 1 discloses a housing having a substantially rectangular parallelepiped shape, and an electrical connector in which a plurality of terminals are arranged on both side faces of the housing at right angles to the circuit board. The terminal of the electrical connector includes a main body piece housed in a housing portion as a recess formed in a side surface of the housing, a fixed terminal piece extending upward from the upper end of the main body piece and connected to the circuit board, and a fixed terminal piece. The lower end of the main body piece extends, and contacts the terminal piece which is convexly curved downward and elastically contacts the other circuit board. The fixed terminal piece has an upper half portion and a lower half portion, and the upper half portion is inserted into a terminal insertion hole to be described later of the circuit board, and the lower half portion extends along the side surface with a predetermined gap therebetween.
在固定有上述固定端子片的電路基板，形成有：用來插通該固定端子片的上半部的端子插通孔。互相相對向而以殼體的收容部所保持的一對端子，其固定端子片彼此的自由狀態的間隔，是較該端子插通孔彼此的間隔更窄。於是，當將電連接器安裝於電路基板時，一對固定端子片彈性變形而互相分離讓間隔加寬，而插通於對應的端子插通孔。結果，將該固定端子片的下半部與殼體的側面的間隔加寬。該固定端子片，藉由在該電路基板的上面側焊接連接，而固定於電路基板。The circuit board to which the fixed terminal piece is fixed is formed with a terminal insertion hole for inserting the upper half of the fixed terminal piece. The pair of terminals held by the housing accommodating portion facing each other with respect to each other, the interval between the free terminal states of the fixed terminal pieces is narrower than the interval between the terminal insertion holes. Then, when the electrical connector is mounted on the circuit board, the pair of fixed terminal pieces are elastically deformed to be separated from each other to widen the interval, and are inserted into the corresponding terminal insertion holes. As a result, the interval between the lower half of the fixed terminal piece and the side surface of the casing is widened. The fixed terminal piece is fixed to the circuit board by soldering and connecting to the upper surface side of the circuit board.
在上述專利文獻1，藉由焊接安裝而以充分的強度將固定端子片固定，所以不需要用來輔助電連接器的保持固定的保持配件等。In the above Patent Document 1, since the fixed terminal piece is fixed with sufficient strength by solder mounting, a holding fitting for fixing the fixing of the electrical connector or the like is not required.
日本特開2002-15793Japan Special Open 2002-15793
可是，在上述專利文獻1的電連接器，在安裝於電路基板之前，在上述固定端子片的下半部與殼體的側面之間，涵蓋該下半部的全區域形成有間隙。當將上述電連接器安裝於電路基板時，藉由電路基板的端子插通孔，固定端子片受到朝遠離殼體側面的方向的力，結果，藉由固定端子片的彈性變形讓該間隙更加寬。也就是說，在該固定端子片的下半部與殼體的側面之間經常形成有間隙，所以可能會因為不經意的外力導致殼體在該間隙的範圍偏離正規位置。However, in the electrical connector of Patent Document 1, a gap is formed between the lower half of the fixed terminal piece and the side surface of the casing to cover the entire area of the lower half before being attached to the circuit board. When the electrical connector is mounted on the circuit board, the terminal piece is biased in a direction away from the side of the casing by the terminal insertion hole of the circuit board, and as a result, the gap is further modified by the elastic deformation of the fixed terminal piece. width. That is, a gap is often formed between the lower half of the fixed terminal piece and the side of the casing, so that the casing may deviate from the normal position in the range of the gap due to an unintended external force.
鑑於這種情形，本發明要提供一種電路基板用電連接器，藉由將殼體的位置固定，來確實地防止殼體從正規位置偏移。In view of such circumstances, the present invention is to provide an electrical connector for a circuit board which is surely prevented from being displaced from a normal position by fixing the position of the casing.
本發明的電路基板用電連接器，是安裝於電路基板上的電連接器，具備有：殼體、以及在互相相對向的殼體的兩個側面處分別排列，形成有藉由該殼體所保持的被保持部的複數的端子；該端子，除了該被保持部之外，具有：形成於上述電路基板側的端部，與該電路基板連接的第一連接部、形成於該電路基板側的相反側的端部，與另外的電路基板連接的第二連接部、以及在該第一連接部與第二連接部之間沿著上述側面延伸的側面相對向部。An electrical connector for a circuit board according to the present invention is an electrical connector mounted on a circuit board, and includes: a housing; and two side faces of the housing facing each other, and the housing is formed by the housing a plurality of terminals of the held portion to be held; the terminal having an end portion formed on the circuit board side in addition to the held portion, and a first connection portion connected to the circuit substrate, formed on the circuit substrate An end portion on the opposite side of the side, a second connecting portion connected to the other circuit board, and a side facing portion extending along the side surface between the first connecting portion and the second connecting portion.
在電路基板用電連接器，在本發明，上述端子的側面相對向部，在靠近第二連接部的位置，在與上述殼體的側面之間具有間隙，在靠近第一連接部的位置，具有彈性壓力地與上述側面抵接，與其中一方的側面抵接的端子的側面相對向部、以及與另一方的側面抵接的端子的側面相對向部，夾持著殼體。In the electric connector for a circuit board, in the side surface facing portion of the terminal, a gap is provided between the side surface facing portion and the second connecting portion, and a position close to the first connecting portion is provided. The housing is abutted against the side surface by elastic pressure, and the side surface facing portion of the terminal abutting on one of the side surfaces and the side surface facing portion of the terminal abutting the other side surface are sandwiched between the housings.
在殼體的兩側面處排列的端子的側面相對向部，具有彈性壓力地抵接於分別相對向的殼體的側面，夾持該殼體，藉此固定著該殼體的位置。而側面相對向部與殼體的側面抵接的是焊接固定於電路基板的第一連接部附近的位置，所以藉由在該位置夾持殼體，而增大殼體的保持力，讓保持變得確實。The side opposing portions of the terminals arranged at both side faces of the housing abut against the sides of the respective opposing housings with elastic pressure, sandwiching the housing, thereby fixing the position of the housing. The side opposing portion abuts against the side surface of the casing at a position welded and fixed to the vicinity of the first connecting portion of the circuit board. Therefore, by holding the casing at the position, the holding force of the casing is increased and the holding is maintained. Become sure.
在殼體的側面，形成有：在與第一連接部之間形成有間隙的缺口部較佳。藉由將在與端子的第一連接部之間形成有間隙的缺口部，形成於殼體的側面，則當第一連接部與電路基板的對應電路部焊接連接時，銲錫也流入到該缺口部內，所以這裡能形成很大的銲錫焊縫。於是，能將端子甚至是連接器對於電路基板更堅固地固定。It is preferable that a side surface of the casing is formed with a notch portion having a gap formed between the first connection portion and the first connection portion. When a notch portion having a gap formed between the first connection portion and the terminal is formed on the side surface of the case, when the first connection portion is soldered to the corresponding circuit portion of the circuit board, the solder also flows into the gap. Inside, so a large solder joint can be formed here. Thus, the terminal or even the connector can be more firmly fixed to the circuit substrate.
在殼體的側面，形成有：與端子的側面相對向部的長軸方向的一部分相對向而開口的凹部較佳。藉由將該凹部形成於殼體的側面，則假設即使銲錫及焊劑於端子的側面相對向部與殼體的側面之間，因為毛細現象上升，而在上述凹部的位置，上述側面相對向部與側面的間隔還是很大很寬，所以銲錫及焊劑不會從該凹部的位置上升。於是，銲錫及焊劑不會到達至第二連接部，所以可以確保第二連接部與其他電路基板的良好連接狀態。It is preferable that a side surface of the casing is formed with a concave portion that opens in a direction in which a part of the longitudinal direction of the side surface of the terminal facing portion faces. By forming the concave portion on the side surface of the casing, it is assumed that even if the solder and the flux are between the side surface facing portion of the terminal and the side surface of the casing, the side surface is opposed to the portion at the position of the concave portion due to the increase in the capillary phenomenon. The spacing from the sides is still very large and wide, so solder and flux do not rise from the position of the recess. Therefore, since the solder and the solder do not reach the second connection portion, it is possible to ensure a good connection state between the second connection portion and the other circuit substrate.
如上述，在本發明，端子的側面相對向部具有彈性壓力地與殼體的兩側面抵接，藉由該側面相對向部夾持殼體，所以即使殼體受到不經意的外力也能防止該殼體偏離正規位置。側面相對向部，在焊接固定於電路基板的第一連接部附近的位置，與殼體的側面抵接而夾持該殼體，所以藉此讓殼體的保持力增大，讓保持變得確實。As described above, according to the present invention, the side facing portions of the terminal are elastically pressed against the both side faces of the casing, and the casing is held by the side opposing portion, so that the casing can be prevented even if an external force is inadvertently applied. The housing deviates from the normal position. The side facing portion is in contact with the side surface of the casing at a position adjacent to the first connecting portion of the circuit board and is clamped to the casing. Therefore, the holding force of the casing is increased to keep the holding. indeed.

Specifically, the held protrusion 23A-1 of the held portion 23A of the curved portion 23 is bitten into the inner wall surface of the holding groove portion 11 by the press-fitting of the curved portion 23, and the terminal 20 is held by the casing 10 .
在端子20已安裝於殼體10的狀態，側面相對向部24，收容於收容溝部14內。該側面相對向部24，延伸成隨著朝向下方漸漸接近溝底面13，在靠近該側面相對向部24的下端的位置，具有彈性壓力地抵接於溝底面13。結果，讓在殼體10的兩側面處分別安裝的端子20的側面相對向部24，具有彈性地抵接於該殼體10的兩溝底面13，藉此讓複數對的端子20的側面相對向部24在兩側夾持該殼體10。而完成連接器1的組裝。In a state where the terminal 20 is attached to the casing 10, the side surface facing portion 24 is housed in the housing groove portion 14. The side facing portion 24 extends so as to gradually approach the groove bottom surface 13 toward the lower side, and abuts against the groove bottom surface 13 at a position close to the lower end of the side surface facing portion 24. As a result, the side opposing portions 24 of the terminals 20 respectively mounted at both side faces of the casing 10 are elastically abutted against the two groove bottom surfaces 13 of the casing 10, thereby allowing the side faces of the plurality of pairs of terminals 20 to be opposed to each other. The housing portion 24 holds the housing 10 on both sides. The assembly of the connector 1 is completed.
在本實施方式，連接器1，在殼體10的各收容溝部14的下方位置形成有缺口部16，如第2圖所示，側面相對向部24的下端側部分及第一連接部21，在與殼體10之間在端子相對向方向隔著間隔。In the present embodiment, the connector 1 has a notch portion 16 formed at a position below each of the housing groove portions 14 of the casing 10. As shown in Fig. 2, the lower end side portion of the side surface facing portion 24 and the first connecting portion 21 are There is a gap between the housing 10 and the housing 10 in the opposing direction.
接著，針對利用連接器1來達成兩個電路基板彼此的連接來說明。首先，如第2圖所示，連接器1，配置於電路基板P1上，藉由將第一連接部21與電路基板P1的對應電路部(沒有圖示)焊接連接，來安裝於電路基板P1加以固定。Next, the connection between the two circuit boards by the connector 1 will be described. First, as shown in FIG. 2, the connector 1 is placed on the circuit board P1, and is attached to the circuit board P1 by soldering the first connection portion 21 to a corresponding circuit portion (not shown) of the circuit board P1. Fixed.
如上述，在本實施方式，藉由缺口部16的存在，在側面相對向部24的下端側部分及第一連接部21與殼體10的側面之間形成有間隙。於是，當該第一連接部21與對應電路部焊接連接時，銲錫附著至從端子20的側面相對向部24移向第一連接部21的彎曲部分，形成銲錫焊縫。此時，上述缺口部16內，也就是在側面相對向部24的下端側部分與殼體10的側面之間形成足夠的空間，所以這裡能形成很大的銲錫焊縫。結果，能將端子20甚至是連接器1對於電路基板P1堅固地固定。As described above, in the present embodiment, a gap is formed between the lower end side portion of the side surface facing portion 24 and the side surface of the first connecting portion 21 and the casing 10 by the presence of the notch portion 16. Then, when the first connecting portion 21 is soldered to the corresponding circuit portion, the solder adheres to the bent portion that is moved from the side surface of the terminal 20 toward the portion 24 toward the first connecting portion 21 to form a solder bead. At this time, in the inside of the notch portion 16, that is, a sufficient space is formed between the lower end side portion of the side surface facing portion 24 and the side surface of the casing 10, a large solder joint can be formed here. As a result, the terminal 20 and even the connector 1 can be firmly fixed to the circuit board P1.
在本實施方式，在殼體10的溝底面13形成有沒入部15，在該沒入部15的位置，端子20的側面相對向部24與溝底面13的間隔很大。於是，假設即使銲錫及焊劑於端子20的側面相對向部24與溝底面13之間藉由毛細現象而上升，該銲錫及焊劑也不會從上述沒入部15的位置上升。結果，銲錫及焊劑不會到達至第二連接部22，所以能確保第二連接部22與其他電路基板P2的良好連接狀態。In the present embodiment, the immersion portion 15 is formed in the groove bottom surface 13 of the casing 10. At the position of the immersion portion 15, the distance between the side surface facing portion 24 of the terminal 20 and the groove bottom surface 13 is large. Therefore, even if the solder and the flux rise between the side surface facing portion 24 and the groove bottom surface 13 of the terminal 20 by the capillary phenomenon, the solder and the solder do not rise from the position of the immersed portion 15. As a result, since the solder and the solder do not reach the second connecting portion 22, the good connection state between the second connecting portion 22 and the other circuit board P2 can be ensured.
接著，如第2圖的箭頭所示，將其他的電路基板P2帶到連接器1的上方，設定在預定位置。當該其他的電路基板P2設定於預定位置時，第二連接部22與設置於該電路基板P2的下面的對應電路部(沒有圖示)抵接，藉由讓第二連接部22及彎曲部23的彈性腕部23B朝下方彈性移位，讓該第二連接部22與該對應電路部彈性接觸。Next, as shown by the arrow in FIG. 2, the other circuit board P2 is brought up to the connector 1 and set at a predetermined position. When the other circuit board P2 is set at a predetermined position, the second connecting portion 22 abuts against a corresponding circuit portion (not shown) provided on the lower surface of the circuit board P2, by allowing the second connecting portion 22 and the bent portion The elastic arm portion 23B of the 23 is elastically displaced downward, and the second connecting portion 22 is elastically brought into contact with the corresponding circuit portion.
在本實施方式，第二連接部22，在端子相對向方向朝殼體10的中央部側彎曲，所以與在端子相對向方向，朝向離開殼體10的中央部的方向彎曲來形成第二連接部的情況相比，從彈性腕部23B涵蓋到第二連接部22的可彈性移位的部分的長度變大。於是，藉此讓第二連接部22的彈性移位量變大，所以能在充分的彈性移位量的基礎下，使該第二連接部22具有很大接觸壓力地與其他電路基板P2的對應電路部接觸。In the present embodiment, since the second connecting portion 22 is bent toward the center portion side of the casing 10 in the direction in which the terminal faces, the second connecting portion 22 is bent in a direction away from the central portion of the casing 10 in the direction in which the terminal faces the second connection. In the case of the portion, the length from the elastic wrist portion 23B to the elastically displaceable portion of the second connecting portion 22 becomes larger. Therefore, the amount of elastic displacement of the second connecting portion 22 is increased, so that the second connecting portion 22 can have a large contact pressure with the other circuit board P2 with a large amount of elastic displacement. The circuit part is in contact.
第一連接部21與電路基板P1的對應電路部焊接的連接器1，以第二連接部22與其他的電路基板P2的對應電路部彈性接觸，藉此將該電路基板P1與其他的電路基板P2電連接。The connector 1 in which the first connecting portion 21 is soldered to the corresponding circuit portion of the circuit board P1 is elastically brought into contact with the corresponding circuit portion of the other circuit board P2 by the second connecting portion 22, whereby the circuit board P1 and other circuit boards are used. P2 is electrically connected.
在本實施方式，藉由於殼體10的兩側面處排列的複數對的端子20的側面相對向部24，夾持著該殼體10，所以在將連接器1安裝於電路基板P1上之後，即使在端子相對向方向受到不經意的外力，也能將該殼體10的位置維持在固定狀態。而在端子相對向方向，能防止該殼體10從正規位置偏離。In the present embodiment, since the housing 10 is sandwiched by the side opposing portions 24 of the plurality of terminals 20 arranged at both side faces of the housing 10, after the connector 1 is mounted on the circuit board P1, The position of the casing 10 can be maintained in a fixed state even if an external force is inadvertently applied to the opposite direction of the terminal. In the opposite direction of the terminal, the housing 10 can be prevented from deviating from the normal position.
在本實施方式，側面相對向部24與殼體10的溝底面13抵接而夾持該殼體10的是該側面相對向部24的靠近下端的位置的部分，也就是焊接固定於電路基板P1的第一連接部21的附近位置的部分，與該側面相對向部24夾持殼體10的是該側面相對向部24的靠近上端的位置的部分的情況相比較，殼體10的保持力變得較大，而能確實地保持。In the present embodiment, the side opposing portion 24 abuts against the groove bottom surface 13 of the casing 10, and the portion of the casing 10 that is close to the lower end of the side facing portion 24 is sandwiched, that is, soldered to the circuit board. The portion of the vicinity of the first connecting portion 21 of P1 is held in comparison with the case where the side facing portion 24 sandwiches the portion of the casing 10 at the position close to the upper end of the side facing portion 24. The force becomes larger and can be surely maintained.
在本實施方式，雖然針對殼體的互相相對向的側面對於電路基板作成直角的情況來說明，而殼體的形狀並不限於此，例如，殼體的兩側面傾斜成隨著朝向上方則互相接近也可以。在該情況，具有相對於電路基板朝直角延伸的形狀的側面相對向部的端子，安裝於殼體的兩側面。藉由安裝這樣形狀的端子，則該端子的側面相對向部，在靠近其下端的位置具有彈性壓力地抵接於殼體的兩側面，夾持該殼體。In the present embodiment, the case where the mutually opposing side faces of the casing are formed at right angles to the circuit board is described, and the shape of the casing is not limited thereto. For example, both side faces of the casing are inclined so as to face each other as they face upward. It is also close. In this case, the terminals having the side facing portions that extend toward the right angle of the circuit board are attached to both side faces of the casing. By attaching the terminal having such a shape, the side surface opposing portion of the terminal abuts against both side faces of the casing with elastic pressure at a position close to the lower end thereof, and the casing is sandwiched.
在本實施方式，端子的側面相對向部作成直線狀，延伸成隨著朝向下方越接近殼體的側面，而端子的形狀並不限於此，例如，側面相對向部相對於電路基板直角地延伸，並且該側面相對向部的靠近下端的位置的一部分朝向殼體的側面凸狀彎曲而形成，該凸狀彎曲部分具有彈性壓力地與殼體的側面抵接，而夾持殼體。In the present embodiment, the side surface of the terminal is linearly formed so as to extend closer to the side surface of the casing as it goes downward, and the shape of the terminal is not limited thereto. For example, the side opposing portion extends at right angles to the circuit board. And a part of the position of the side opposing portion near the lower end is formed to be convexly curved toward the side surface of the casing, and the convex curved portion abuts against the side surface of the casing with elastic pressure to sandwich the casing.
在本實施方式，排列於殼體的兩側面的端子，在端子排列方向互相在相同位置被保持，而也可取代該方式，將排列於各側面的端子在端子排列方向互相錯開，在作成所謂交錯狀的位置加以保持。In the present embodiment, the terminals arranged on both side faces of the casing are held at the same position in the terminal arrangement direction. Instead of this, the terminals arranged on the respective side faces may be shifted from each other in the terminal arrangement direction. The staggered position is maintained.
在本實施方式，排列於殼體的兩側面的端子的數量是相同數量，而也可取代該方式，在各側面排列互相不同數量的端子也可以。In the present embodiment, the number of terminals arranged on both side faces of the casing is the same, and instead of this, a different number of terminals may be arranged on each side.
