<電連接器的組裝方法> <Assembling method of electrical connector>
以下，詳細說明本發明的第一實施例涉及的電連接器1的組裝方法。 Hereinafter, a method of assembling the electrical connector 1 according to the first embodiment of the present invention will be described in detail.
首先，對於預先準備的殼體10的***孔11將電纜130從前方***。此時，無需使電纜130的導電體130b露出。 First, the cable 130 is inserted from the front side with respect to the insertion hole 11 of the housing 10 prepared in advance. At this time, it is not necessary to expose the conductor 130b of the cable 130.
然後，將電纜130***到***孔11中，直至電纜130的***方向的前端抵接於抵接壁部14。 Then, the cable 130 is inserted into the insertion hole 11 until the front end of the insertion direction of the cable 130 abuts against the abutment wall portion 14.
然後，將一對接頭20的兩股型連接部21***到連通槽13中，在兩股型連接部21的二股之間將電纜130的絕緣體130a刺破。 Then, the two-piece connecting portion 21 of the pair of joints 20 is inserted into the communication groove 13, and the insulator 130a of the cable 130 is pierced between the two strands of the two-type connecting portion 21.
然後，將兩股型連接部21進一步***到連通槽13中，使兩股型連接部21與電纜130的導電體130b連接。此時，兩股型連接部21以陷入導電體130b中的狀態與導電體130b連接。 Then, the two-strand connector portion 21 is further inserted into the communication groove 13, and the two-strand connector portion 21 is connected to the conductor 130b of the cable 130. At this time, the two-strand connector portion 21 is connected to the conductor 130b in a state of being trapped in the conductor 130b.
接著，藉由將兩股型連接部21進一步***到連通槽13中，使兩股型連接部21的前端卡合在支柱部15的卡合孔19(參照圖3)中。並且，接頭20的卡合突起26卡合在殼體10的卡合凹部18中。 Then, the two-strand connector portion 21 is further inserted into the communication groove 13, and the distal end of the two-strand connector portion 21 is engaged with the engagement hole 19 (see FIG. 3) of the column portion 15. Further, the engagement projection 26 of the joint 20 is engaged with the engagement recess 18 of the housing 10.
在電纜130的導電體130b與接頭20的兩股型連接部21相連接的狀態下，兩股型連接部21的抵接部24以整個表面抵接於殼體10的連通槽13的上壁16、及下壁17。此時，抵接部24藉由兩股型連接部21受到連接在兩股型連接部21的二股之間的電纜130的導電體130b向撐開方向的擠壓，對上壁16、及下壁17進行擠壓。如此，因為藉由抵接部24以面相抵接上壁16、及下壁17而分散抵接部24所致的對殼體10的擠壓力，而能防止殼體10向外部膨脹，並且能夠良好地保持外觀上的視覺美感。此外，由於抵接部24以面相抵接連通槽13的上壁16、及下壁17使接頭20保持在殼體10，因此能夠將接頭20穩定地保持在殼體10。 In a state where the conductor 130b of the cable 130 is connected to the two-piece connecting portion 21 of the joint 20, the abutting portion 24 of the two-strand type connecting portion 21 abuts against the upper wall of the communication groove 13 of the casing 10 with the entire surface. 16, and the lower wall 17. At this time, the abutting portion 24 is pressed by the conductor 130b of the cable 130 connected between the two strands of the two-type connecting portion 21 by the two-strand connecting portion 21, and the upper wall 16 and the lower portion are pressed. The wall 17 is pressed. In this manner, since the pressing force on the casing 10 due to the abutting portion 24 is dispersed by the abutting portion 24 abutting against the upper wall 16 and the lower wall 17, the casing 10 can be prevented from being inflated to the outside, and It can maintain the visual aesthetic of the appearance well. Further, since the abutting portion 24 abuts against the upper wall 16 of the communication groove 13 and the lower wall 17 to hold the joint 20 in the casing 10, the joint 20 can be stably held by the casing 10.
藉由電纜130的導電體130b對兩股型連接部21向撐開方向S1(參照圖7)進行擠壓，凹部25的角27以陷入上壁16、及下壁17的方式卡止。藉此，即使在接頭20從連通槽13脫離的方向(圖7中x軸的正方向)上對接頭20施加力，也能藉由角27卡止於上壁16、及下壁17，從而對接頭20進行止脫。 The two-shaped connecting portion 21 is pressed in the expanding direction S1 (see FIG. 7) by the conductor 130b of the cable 130, and the corner 27 of the recess 25 is locked in the upper wall 16 and the lower wall 17. Thereby, even if a force is applied to the joint 20 in the direction in which the joint 20 is detached from the communication groove 13 (the positive direction of the x-axis in FIG. 7), the upper wall 16 and the lower wall 17 can be locked by the angle 27, thereby The joint 20 is prevented from coming off.
藉由上述方法組裝的電連接器1，從相對於安裝在基板上的對側連接器前方連接，接著，在對側連接器的導電接頭抵接於接頭20的對側連接器連接部22的狀態下，由後方朝向前方滑動著與對側連接器連接部22連接。電連接器1在與對側連接器相連接的狀態下，藉由向前方拉動而解除連接於對側連接器，接著，在對側連接器的導電接頭抵接於接頭20的對 側連接器連接部22的狀態下，由前方朝向後方滑動著解除連接於對側連接器連接部22。雖然伴隨著上述動作對接頭20施加了從外部向前後方向的力，但是藉由接頭20的卡合突起26卡合於殼體10的卡合凹部18，同時兩股型連接部21的前端卡合在卡合孔19中，能使接頭20相對於殼體10穩定地保持之。 The electrical connector 1 assembled by the above method is connected from the front side of the opposite side connector mounted on the substrate, and then the conductive joint of the opposite side connector abuts against the opposite side connector connecting portion 22 of the joint 20. In the state, the rear side connector connecting portion 22 is connected to the front side by sliding. When the electrical connector 1 is connected to the opposite connector, the connector is disconnected from the opposite connector by pulling forward, and then the pair of the conductive connector of the opposite connector abuts against the connector 20. In the state of the side connector connecting portion 22, the front connector connecting portion 22 is released by being slid rearward from the front side. Although the force of the front and rear directions from the outside is applied to the joint 20 with the above-described operation, the engaging projection 26 of the joint 20 is engaged with the engaging recess 18 of the casing 10, and the front end of the two-shaped connecting portion 21 is stuck. Engagement in the engaging hole 19 enables the joint 20 to be stably held with respect to the housing 10.
根據本實施例，藉由形成接頭20的抵接部24以面抵接於上壁16、及下壁17的結構，殼體10的上壁16、及下壁17的厚度即使變薄，也不會向外部膨脹，因此能夠使殼體10的上壁16、及下壁17的厚度變薄，實現電連接器1的低背化、及小型化。 According to the present embodiment, by forming the abutting portion 24 of the joint 20 to face the upper wall 16 and the lower wall 17, the thickness of the upper wall 16 and the lower wall 17 of the casing 10 is thinned. Since it does not expand to the outside, the thickness of the upper wall 16 and the lower wall 17 of the casing 10 can be made thin, and the electrical connector 1 can be reduced in height and size.
此外，根據本實施例，由於在接頭20中不從抵接部24形成突出的部分，相較於以往，由板材形成接頭20時不會產生取材的浪費。 Further, according to the present embodiment, since the protruding portion is not formed in the joint 20 from the abutting portion 24, the waste of the material is not generated when the joint 20 is formed from the plate material as compared with the prior art.
此外，根據本實施例，由於能夠減小接頭20的上下方向的寬度，因此能夠降低殼體10的連通槽13的上下方向的高度，從而能夠實現電連接器1的低背化。 Further, according to the present embodiment, since the width of the joint 20 in the vertical direction can be made small, the height of the communication groove 13 of the casing 10 in the vertical direction can be reduced, and the electrical connector 1 can be lowered in height.

殼體50具有貫通孔51，貫通孔51在板厚度方向即上下方向上貫通，使得在相對於卡合孔19、及連通槽13的兩股型連接部21的***方向上比卡合孔19更靠前的部分向外部開放。貫通孔51被形成為橫跨左右方向 的寬度L1(參照圖9)。在此，寬度L1為，當卡合在卡合孔19中的兩股型連接部21的前端抵接於支柱部15，卡止壁52的上端可抵接在凹部25的角27與角28之間時的寬度。在殼體50，設置有連續形成於連通槽13的上壁16、及下壁17上並且與相對於連通槽13的兩股型連接部21的***方向正交的卡止壁52。卡止壁52構成貫通孔51的一部分，並且被設置成與支柱部15相對。另外，殼體50中的上述以外的結構與殼體10的結構相同，所以省略其說明。 The case 50 has a through hole 51 which penetrates in the plate thickness direction, that is, the up-and-down direction, so that the insertion hole 19 is inserted in the insertion direction of the two-type connection portion 21 with respect to the engagement hole 19 and the communication groove 13. The more advanced part is open to the outside. The through hole 51 is formed to cross the left and right direction The width L1 (refer to Figure 9). Here, the width L1 is such that when the front end of the two-shaped connecting portion 21 engaged in the engaging hole 19 abuts against the pillar portion 15, the upper end of the locking wall 52 can abut against the corner 27 and the corner 28 of the recess 25. Between the widths. The casing 50 is provided with a locking wall 52 which is continuously formed on the upper wall 16 and the lower wall 17 of the communication groove 13 and which is orthogonal to the insertion direction of the two-shaped connecting portion 21 with respect to the communication groove 13. The locking wall 52 constitutes a part of the through hole 51 and is provided to face the pillar portion 15 . In addition, the configuration other than the above in the casing 50 is the same as that of the casing 10, and therefore the description thereof will be omitted.
<電連接器的組裝方法> <Assembling method of electrical connector>
以下，詳細說明本發明的第二實施例涉及的電連接器2的組裝方法。 Hereinafter, a method of assembling the electrical connector 2 according to the second embodiment of the present invention will be described in detail.
藉由由電纜130的導電體130b對兩股型連接部21在撐開方向S1(參照圖9)上擠壓，使得連接抵接部24與凹部25的角27落入貫通孔51的同時，使凹部25卡止於卡止壁52。藉此，即使在接頭20從連通槽13脫離的方向(圖9中x軸的正方向)上對接頭20中施加力，也能藉由使凹部25卡止於卡止壁52來對接頭20進行止脫。 The two-shaped connecting portion 21 is pressed by the conductor 130b of the cable 130 in the expanding direction S1 (refer to FIG. 9) so that the corner 27 of the connecting abutting portion 24 and the recess 25 falls into the through hole 51. The recess 25 is locked to the locking wall 52. Thereby, even if a force is applied to the joint 20 in the direction in which the joint 20 is detached from the communication groove 13 (the positive direction of the x-axis in FIG. 9), the joint 20 can be engaged by locking the concave portion 25 to the locking wall 52. Take a stop.
另外，因為電連接器2的上述組裝方法以外的組裝方法與電連接器1的組裝方法相同，所以省略其說明。 In addition, since the assembly method other than the above-described assembly method of the electrical connector 2 is the same as the method of assembling the electrical connector 1, the description thereof will be omitted.
根據本實施例，除了上述第一實施例的效果以外，由於凹部25卡止於與連通槽13的兩股型連接部21的***方向呈垂直的卡止壁52，因而還能夠確保將接頭20保持在殼體50中。 According to the present embodiment, in addition to the effects of the first embodiment described above, since the recessed portion 25 is locked to the locking wall 52 which is perpendicular to the insertion direction of the two-shaped connecting portion 21 of the communication groove 13, the joint 20 can be secured. It is held in the housing 50.
另外，雖然在本實施例中設置了貫通孔51，但是也可以在連通槽中設置非貫通的凹部，將此凹部的側壁的一部分作為卡止壁52。在設置凹部的情況下，由於能夠消除殼體50的外部表面中的凹凸，因此能夠良好地保持外觀上的視覺美感。 Further, although the through hole 51 is provided in the present embodiment, a non-penetrating concave portion may be provided in the communication groove, and a part of the side wall of the concave portion may be the locking wall 52. In the case where the concave portion is provided, since the unevenness in the outer surface of the casing 50 can be eliminated, the visual aesthetic appearance can be favorably maintained.
