具体实施方式
为了更加清楚地阐述本申请的上述目的、特征和优点，在该部分结合附图详细说明本申请的具体实施方式。除了在本部分描述的各个实施方式以外，本申请还能够通过其他不同的方式来实施，在不违背本申请精神的情况下，本领域技术人员可以做相应的改进、变形和替换，因此本申请不受该部分公开的具体实施例的限制。本申请的保护范围应以权利要求为准。
(第一实施方式)
如图1至图19所示，本申请提出一种板对板连接器，其包括公头1和母座2，公头1和母座2能够相互配合地连接。板对板连接器可以应用于保护性电路装置中，公头1和母座2首次连接后连接器能正常使用，而当试图将它们分 离时，公头1和母座2不易分离。并且将公头1和母座2强制分离后，连接器被破坏而无法被再次使用，从而防止信息被窃取。
(公头)
如图1至图12所示，公头1包括公头塑胶体11、公头PCB(印刷电路板)10、公头端子12、公头侧金属片13、公头金属固定片41、公头金属外壳43和公头焊接金属条44。
公头端子12安装于公头塑胶体11，公头端子12、公头金属固定片41和公头焊接金属条44连接于公头PCB 10，例如公头端子12、公头金属固定片41和公头焊接金属条44焊接于公头PCB 10。公头金属外壳43部分地覆盖公头塑胶体11并且与公头PCB 10电连接。
(公头PCB)
如图4和12所示，公头PCB 10设置有第一公头焊盘101、第二公头焊盘102、第三公头焊盘103、PCB插槽104和公头PCB插孔105。
第二公头焊盘102位于公头PCB 10的主体中央的大部分区域，多个第二公头焊盘102沿公头PCB 10的长度方向X排列成排。在公头PCB 10的宽度方向Y上，第二公头焊盘102排列形成多排，例如可以排列为3排。3排第二公头焊盘102用于和公头端子12焊接相连，使公头端子12焊接在公头PCB 10上。
第一公头焊盘101和第三公头焊盘103分别位于第二公头焊盘102在宽度方向Y上的两侧。第一公头焊盘101用于和公头金属外壳43焊接相连，使公头金属外壳43焊接在公头PCB 10上。第三公头焊盘103用于和公头金属固定片41焊接相连，使公头金属固定片41焊接在公头PCB 10上。
公头PCB插槽104和公头PCB插孔105位于公头PCB 10的长度方向X上的两端部。公头PCB插槽104和公头PCB插孔105可以贯穿公头PCB10。
公头PCB插槽104用于使公头侧金属片13嵌入，从而可以通过公头侧金属片13使公头PCB 10和公头塑胶体11稳定地连接。
公头PCB插孔105用于使公头塑胶体11上向外延伸出的插针嵌入，从而使公头塑胶体11与公头PCB 10的稳定地连接。
(公头塑胶体)
如图1至图4以及图9所示，公头塑胶体11设置有容纳槽111，容纳槽111可以部分地容纳母座2。容纳槽111的底面112开设有多个公头插槽110，使公头端子12能够插嵌在公头插槽110内。
公头塑胶体11的顶面设置有塑胶体卡槽117，塑胶体卡槽117用于与公头金属外壳43配合连接，使公头金属外壳43与公头塑胶体11稳定地连接。
在容纳槽111的长度方向上相对的两个第一内侧面113设置有公头塑胶体槽道118，公头塑胶体槽道118沿公头1的厚度方向Z延伸，公头塑胶体槽道118可以限制母座2沿公头1的厚度方向Z滑动从而与公头1配合连接。
如图8所示，在容纳槽111的宽度方向上相对的两个第二内侧面114设置有公头塑胶体卡槽119，公头塑胶体卡槽119可以和公头金属固定片41卡接，使公头金属固定片41可以被稳定地安装。
如图9所示，在公头塑胶体11的厚度方向Z上的一侧面(顶面)设置有第一安装槽115，第一安装槽115沿公头塑胶体11的厚度方向Z延伸，第一安装槽115与公头插槽110连通。在公头塑胶体11的宽度方向Y上的一侧面设置有第二安装槽116，第二安装槽116与第一安装槽115连通，使公头塑胶体11形成用于插入公头端子12的空间，便于将公头端子12插入公头插槽110。
公头塑胶体11的侧面设置有向外延伸的插针，插针能够插入公头PCB插孔105内，使公头塑胶体11与公头PCB 10可以保持稳定的连接。
(公头侧金属片)
如图1、图3、图4和图5所示，公头侧金属片13安装于公头塑胶体11的长度方向上的两端部，通过公头侧金属片13可以将公头塑胶体11稳定地连接于公头PCB 10。
具体地，公头侧金属片13大致为T字形，公头侧金属片13整体上卡嵌于公头塑胶体11，公头侧金属片13的一端插入公头PCB插槽104内，从而公头塑胶体11能够稳定地连接于公头PCB 10。
可以理解，在连接器的生产组装过程中，需要对公头1进行二次过炉， 为避免在二次过炉时，由于公头塑胶体11的一侧过重而导致公头塑胶体11和公头PCB 10脱落，使用公头侧金属片13连接公头塑胶体11和公头PCB 10。
(公头端子)
如图2和图4至图6所示，公头端子12可以弯折形成而呈L型，公头端子12包括第一公端部121和第二公端部122。第一公端部121与第二公端部122垂直，第一公端部121焊接于公头PCB 10，第二公端部122穿过公头插槽110用于和母座2实现电连接。
由于公头端子12呈L型，公头PCB 10安装在公头塑胶体11的宽度方向上的一侧面。公头端子12可以为片状的结构，第一公端部121垂直于公头PCB 10，第二公端部122与公头PCB 10平行。
公头端子12设置有多个，多个公头端子12按照阵列方式排列插嵌在公头插槽110内。多个公头端子12在公头1的宽度方向上可以设置有多组，例如多个公头端子12在公头1的宽度方向上设置三组。三组公头端子12的第二公端部122的长度相同，第一公端部121的长度依次缩短。距离公头PCB 10较近的公头端子12的第一公端部121较短，距离公头PCB 10较远的公头端子12的第一公端部121较长，使多组第一公端部121均可以焊接到公头PCB 10。
如图6所示，第二公端部122包括第一部31，第一部31能够与母座2的第二部32(参见图18)配合，当分离公头1和母座2时，第二部32与第一部31相抵，从而阻止所述公头1和母座2分离。
如图6所示，第二公端部122包括公头接触段1221、公头卡槽段1222以及公头头段1223，在第一公端部121指向第二公端部122的端部的方向上，公头接触段1221、公头卡槽段1222以及公头头段1223依次相连。其中公头卡槽段1222以及公头头段1223可以作为第一部31。第二公端部122是插接入母座2的部分，公头接触段1221、公头卡槽段1222以及公头头段1223均位于第二公端部122，它们是公头1与母座2电连接的部分。
公头接触段1221的宽度大于公头卡槽段1222的宽度，公头头段1223的宽度大于公头卡槽段1222的宽度。
公头头段1223可以呈弹头状，当其插入母座端子22时，其能够使后述的两个结合臂224(参见图18)被撑开，起到导向作用。
公头头段1223与公头卡槽段1222的连接部分形成台阶部1224，在公头端子12和母座端子22脱离时，台阶部1224能够对第二部32施力，使第二部32脱落，母座端子22被破坏而不能再次与公头1连接。优选地，台阶部1224可以为朝向公头头段1223凹陷的凹弧面。
公头接触段1221和公头卡槽段1222的连接部分形成导向斜面1225，在公头端子12插入母座2时，导向斜面1225能够使得两个结合臂224被撑开。
第二公端部122设置有定位凸起123，定位凸起123位于第二公端部122的一侧板面上，在公头插槽110内设置有与定位凸起123相适配的定位凹槽。从而容易保证公头端子12安装的正确性，并且使公头端子12能够稳定的容置在公头插槽110内，即使当公头端子12与公头PCB 10脱落，公头端子12也不会掉落至母座2内。
(公头金属固定片)
如图2至图5和7所示，公头金属固定片41配置在公头端子12的宽度方向的两侧，并且安装在公头塑胶体11的容纳槽111的内壁上。公头金属固定片41不仅能够起到屏蔽信号的作用，还能够起到保护连接器的作用。
如图7所示，公头金属固定片41包括公头固定本体410、公头卡勾411、公头接触片412、公头弹片413和公头卡槽414。
在公头1的厚度方向上，公头卡勾411位于公头固定本体410的一端，公头接触片412位于公头固定本体410的另一端。公头卡勾411与公头塑胶体卡槽119连接，公头接触片412与公头PCB 10电连接。位于公头1的宽度方向Y两侧的两个公头金属固定片41分别通过金属外壳43和公头焊接金属条44与公头PCB 10电连接。
公头弹片413的一端(上端)弹性地连接于公头固定本体410，公头弹片413的另一端(下端)向公头塑胶体11的所在侧延伸(此处的上端是以公头1与母座2连接时，母座2位于公头1的下方的状态来定义的)。在公头1与母座2 适配连接到位时，母座2对公头弹片413施加压力使其发生形变，公头弹片413对母座2的母座金属固定片42施压压力，从而使公头1和母座2相互挤压，增加连接稳定性。
公头卡槽414形成于公头固定本体410，在公头1与母座2适配连接到位时，公头卡槽414用于容纳母座2的母座弹片423(参见图16)，增加了公头1与母座2的分离难度。
(公头金属外壳)
如图10所示，公头金属外壳43的截面呈L型，公头金属外壳43可以覆盖公头塑胶体11的侧面和顶面。公头金属外壳43包括第一外壳本体431和第二外壳本体432，第一外壳本体431和第二外壳本体432相互垂直地连接在一起。
第一外壳本体431的端部设置有外壳接触片433，外壳接触片433用于与公头接触片412接触实现电连接。第二外壳本体432的端部设置有外壳焊接片434，外壳焊接片434用于与公头PCB 10的第一公头焊盘101焊接。
第二外壳本体432的面向公头塑胶体11的一面设置有多个凸起的外壳卡片435，外壳卡片435用于和公头塑胶体11外壁的塑胶体卡槽117配合，从而使公头金属外壳43与公头塑胶体11稳定地连接。
(公头焊接金属条)
如图11所示，公头焊接金属条44包括金属条焊接片440和金属条接触片441，金属条焊接片440焊接于第三公头焊盘103，金属条接触片441和公头接触片412接触，从而通过公头焊接金属条44使公头PCB 10与公头金属固定片41电连接。
(母座)
如图1、图2和图13至图19所示，母座2包括母座塑胶体21、母座PCB20、母座端子22和母座金属固定片42，母座塑胶体21和母座PCB20连接，母座端子22和母座金属固定片42均焊接于母座PCB20。
(母座塑胶体)
如图13和图14所示，母座塑胶体21可以为立方体块状，母座塑胶体21开 设有多个母座插槽210，多个母座插槽210呈阵列排列，母座插槽210沿母座塑胶体21的厚度方向贯穿母座塑胶体21。母座端子22安装在母座插槽210内，母座端子22包括母座本体221和母座弹臂部222。母座本体221和母座PCB20焊接在一起，母座弹臂部222嵌在母座插槽210内。当公头1与母座2连接时，第二公端部122能够插入到母座插槽210内与母座端子22接触。
如图17所示，母座插槽210的内部设置有母端限位结构2100，母端限位结构2100包括母端下限制部2101和母端上限位部2102。
母端下限制部2101可以位于母座插槽210的宽度方向上的两侧面，从而限制母座端子22在母座插槽210内沿宽度方向的活动。母端上限位部2102靠近母座插槽210的开口部分。母端上限位部2102可以限制母座端子22在母座插槽210内沿长度方向的活动，将母座端子22限位贴合在母座插槽210的内壁上，提高母座端子22在母座插槽210内的稳定性。
通过母端限位结构2100使母座端子22贴附于母座插槽210的内壁，使母座端子22的后述接合部220对准母座插槽210的开口，从而使得公头端子12插入母座插槽210时，公头端子12仅与接合部220接触，而不与母座端子22的其他部分接触。
母座塑胶体21的长度方向X上的两端设置有母座塑胶体凸起211，在将公头1和母座2适配安装时，母座塑胶体凸起211可以沿公头塑胶体槽道118滑动，便于母座塑胶体21与所述公头塑胶体11的适配安装。
(母座PCB)

第一母座焊盘201可以设置有两排，两排第一母座焊盘201位于第二母座 焊盘202的宽度方向Y上的两侧。第一母座焊盘201用于和母座金属固定片42焊接相连，使母座金属固定片42焊接在母座PCB 20上。
母座PCB插孔203用于使母座塑胶体21的插针插入。
(母座端子)
如图13至图19所示，母座端子22包括母座本体221、母座弹臂部222、接合部220。
母座弹臂部222可以由母座本体221向上延伸形成，接合部220悬接于母座弹臂部222，接合部220用于使母座端子22与公头端子12接触，并且限制母座端子22和公头端子12脱离。接合部220可以作为与第一部31配合的第二部32。
母座弹臂部222包括弹臂本体以及设置于弹臂本体的弹臂凹槽2220，弹臂凹槽2220将弹臂本体分成两个母端弹片。接合部220包括两个结合臂224，两个结合臂224可以关于弹臂凹槽2220对称，两个结合臂224围成接合空间2200。两个结合臂224可以分别设置在两个母端弹片的上部。
接合空间2200由上到下依次包括导引段220-1、过渡段220-3和限位段220-4，接合空间2200的上部靠近母座插槽210的开口部分，接合空间2200的下部靠近母座插槽210的底部。
在公头端子12插入接合部220的方向上，导引段220-1位于限位段220-4的上游侧，限定导引段220-1的两个结合臂224的侧面渐缩呈倒“八”字型，从而结合臂224能够引导公头端子12进入接合空间2200。
在公头端子12插入接合部220的方向上，限位段220-4位于导引段220-1的下游侧，限定限位段220-4的两个结合臂224的侧面渐缩呈倒“八”字型。
如图18所示，在公头端子12和母座端子22适配安装的状态下，公头接触段1221和限定限位段220-4的两个结合臂224的侧面接触，公头接触段1221将结合臂224撑开，公头头段1223和部分的公头卡槽段1222位于接合空间2200的范围之外。
公头接触段1221和公头头段1223的宽度大于结合臂224在自然状态下限 位段220-4的宽度。在公头端子12和母座端子22脱离时，台阶部1224能够对结合臂224施力，使结合臂224脱落，母座端子22被破坏。
过渡段220-3位于导引段220-1和限位段220-4之间，限定过渡段220-3的两个结合臂224的侧面可以是平行的。限定过渡段220-3的结合臂224的部分连接于母端弹片。
(母座金属固定片)
如图13和图14所示，母座金属固定片42配置在母座端子22的宽度方向的两侧，并且安装在母座塑胶体21的外壁面。母座金属固定片42不仅能够起到屏蔽信号的作用，还能够使母座塑胶体21稳定地安装于母座PCB 20。
如图14和图16所示，母座金属固定片42包括母座固定本体420、母座接触片421、母座卡勾422、母座弹片423和弹片通槽424。
在母座2的厚度方向上，母座接触片421位于母座固定本体420的一端，母座卡勾422位于母座固定本体420的另一端。母座接触片421焊接于第一母座焊盘201，使母座接触片421和母座PCB 20电连接。母座卡勾422与母座塑胶体21的母座卡槽相适配，使母座金属固定片和母座塑胶体21连接。
母座弹片423的一端(上端)弹性地连接于母座固定本体420，母座弹片423的另一端(下端)向远离母座塑胶体21的外侧延伸(此处的上端是以公头1与母座2连接时，母座2位于公头1的下方的状态来定义的)。在公头1和母座连接时，母座弹片423可以和公头卡槽414相适配。母座弹片423可以沿母座固定本体420的长度方向设置有多个。
弹片通槽424形成于母座固定本体420，弹片通槽424的位置可以和母座弹片423是对应的，即母座弹片423的一端(上端)连接于弹片通槽424的上边缘。
在公头1与母座2安装的过程中，公头金属固定片41可以对母座弹片423施加使母座弹片423朝母座塑胶体21变形的力。如图19所示，当母座弹片423进入到公头卡槽414内之后，母座弹片423可以恢复形变。在试图将公头1与母座2分离时，即公头1向着远离母座2的方向移动时，母座弹片423会抵靠在 公头卡槽414的边缘而使得母座弹片423无法脱离公头卡槽414，强行使公头1与母座2分离将导致母座弹片423损坏，母座2不能正常使用。
(第二实施方式)

(公头端子)
如图20和图23所示，公头端子12可以弯折形成而呈L型，公头端子12包括第一公端部121和第二公端部122。第一公端部121与第二公端部122垂直，第一公端部121焊接于公头PCB 10，第二公端部122穿过公头插槽110用于和母座2实现电连接。
(母座端子)

母座弹臂部222可以由母座本体221向上延伸形成，接合部220悬接于母座弹臂部222，接合部220用于使母座端子22与公头端子12接触，并且限制母座端子22和公头端子12脱离。
母座弹臂部222包括弹臂本体以及设置于弹臂本体的弹臂凹槽2220，弹臂凹槽2220将弹臂本体分成两个母端弹臂。接合部220包括两个结合臂224，两个结合臂224可以关于弹臂凹槽2220对称，两个结合臂224围成接合空间2200。两个结合臂224可以分别设置在两个母端弹片的上部。

公头接触段1221和公头头段1223的宽度大于结合臂224在自然状态下夹持段220-2和限位段220-4的宽度，使得当公头端子12插入到母座端子22内时，两个结合臂224的限定夹持段220-2和限位段220-4的部分被撑开，夹持公头接触段1221，从而增加公头端子12与母座端子22之间的接触性能。
限定夹持段220-2的两个结合臂224的侧面可以为朝向接合空间2200凸起的弧面。限定夹持段220-2的两个结合臂224与公头接触段1221的接触为圆弧面接触，使得两者的接触更稳定。
公头卡槽段1222的宽度大于结合臂224在自然状态下限位段220-4和卡紧段220-5的宽度，使得当公头端子12插入到母座端子22内时，两个结合臂224的限定限位段220-4和卡紧段220-5的部分被撑开，夹持公头卡槽段1222，从而增加公头端子12与母座端子22之间的接触性能。
过渡段220-3包括第一过渡子段220-3-1和第二过渡子段220-3-2，第一过渡子段220-3-1位于第二过渡子段220-3-2上端。
第一过渡子段220-3-1的上端与夹持段220-2的下端相连，在公头端子12插入接合部220的方向上，第一过渡子段220-3-1的宽度从上到下逐渐增大，限定第一过渡子段220-3-1的两个结合臂224的侧面与接合空间2200的中心轴线形成夹角。
限定第一过渡子段220-3-1的结合臂224的部分通过连接片223连接于母端弹片，夹持段220-2的下端与母座弹片的上端齐平，即夹持段220-2和导引段220-1位于母座弹片的上方。在公头端子12插入接合部220，结合臂224以第一过渡子段220-3-1为中心转动，可以使限定限位段220-4的结合臂224向内侧卡的更紧密。
第二过渡子段220-3-2的上端与第一过渡子段220-3-1的下端连接，第二过渡子段220-3-2的下端与限位段220-4的上端连接。第二过渡子段220-3-2的 宽度可以从上到下保持不变，限定第二过渡子段220-3-2的两个结合臂224的侧面与接合空间2200的中心轴线平行。
在公头端子12插入接合部220的方向上，卡紧段220-5设置于限位段220-4的末端，卡紧段220-5的宽度可以从上到下保持不变。
限定卡紧段220-5的结合臂224的内壁与接合空间220的中心轴线平行；且所述卡紧段220-5的下端面2201为倾斜平面或者为与公头头段1223与公头卡槽段1222的连接面的凹弧面相适配的凸弧面，即限位段220-4和卡紧段220-5位于公头卡槽段1222内。
限定卡紧段220-5的结合臂224的底部可以是与台阶部1224的凹弧面配合的凸弧面或者平面。
如图23所示，在公头端子12和母座端子22适配安装的状态下，公头接触段1221和限定夹持段220-2的两个结合臂224的侧面接触，公头卡槽段1222和限定卡紧段220-5的两个结合臂224的侧面接触。公头头段1223和部分的公头卡槽段1222位于接合空间2200的范围之外。
公头头段1223的宽度大于结合臂224在自然状态下限位段220-4和卡紧段220-5的宽度。在公头端子12和母座端子22脱离时，台阶部1224能够对结合臂224施力，使结合臂224脱落，母座端子22被破坏。
优选地，两个结合臂224、母座弹臂222和母座本体221可以一体成型。
本申请通过对公头端子12和母座端子22的结构的设计，使得在强制分离公头1和母座2时，会对连接器整体造成破坏，从而起到限制公头1与母座2分离的目的，避免强制分离的连接器被再次使用，保护了连接器的安全。
