根据本发明的一个实施例，所述底座的数量为至少两个，该至少两个底座结构相同，并拼接在一起。
相较于现有技术，本发明具有以下有益效果：
1、本发明采用激光熔焊代替焊接工艺实现内导线与引出件的内接部分、输入夹簧电连接，能够避免引入焊接污染，同时较好地保护了输入夹簧、引出件的原有形貌及属性。

本实施例中，所述引出件2的内接部分设有U形夹口221，输入夹簧4设有U形夹口40。内导线5的两端分别卡接部51，例如是向上弯折的延伸部，内导线5一端的卡接部51卡于内接部分的夹口221，并且内导线5端部的卡接部51透过夹口221延伸，高于夹口221的部分被激光熔化并瞬间往下流，填充了夹口221，从而将内导线5与引出件2的内接部分熔接在一起；内导线5另一端的卡接部51卡于输入夹簧4的夹口40，并且内导线5端部的卡接部51透过夹口40延伸，高于夹口40的部分被激光熔化并瞬间往下流，填充了夹口40，从而将内导线5与输入夹簧4熔接在一起。内导线5两端的卡接部51分别高于相应的夹口，如图5所示，该卡接部51顶端与夹口221的高度差为h。所述激光熔焊是指激光高温融化内导线的卡接部51，融化的铜液将内导线与输入夹簧或引出件熔接在一起。所述夹口能够对内导线5端部提供预定位，使内导线5端部更便于进行后续的激光熔焊工艺。此外，夹口还使内导线5的预定位操作非常便捷。
本实施例中，所述底座1设有连通所述第一容腔11、第二容腔12的导线通道13， 所述内导线5沿底座1的长度方向设置，且所述内导线5沿所述底座1的宽度方向压入该导线通道13。
本实施例中，如图2所示，所述外接部分为一侧板21，内接部分为一底板22，该侧板21底端与底板22一端一体相连。侧板21顶端设有限位部，该限位部卡入所述第一容腔11侧壁对应设置的第一限位槽111中，如图5所示。所述限位部具体包括若干相互间隔的限位块211，各限位块211分别向所述侧板21外侧向上倾斜延伸。所述侧板21外侧指侧板21背离所述弹簧片3的一侧。底板22设有所述夹口221，且该底板22另一端顶面设有凸部222，凸部222也可以设置于底板22的底面，或者底板22的底面和顶面同时设置凸部222。底板22端部及该凸部222设置于所述第一容腔11底部对应设置的第二限位槽112，并呈过盈配合，如图5所示。所述限位部即多个限位块211对引出件2提供横向定位，所述凸部222对引出件2提供竖向定位，从而提高引出件2的抗冲击能力，提高本发明工作的稳定性。
本实施例中，所述弹簧片3呈倒置的V形，且其一边抵于所述第一容腔11侧壁，另一边中部位置设有长条形狭缝31，并与所述外接部分即所述侧板21配合。所述第一容腔11中设有一支轴14，所述弹簧片3拐弯部位呈圆弧状，并绕过该支轴14。所述侧板21内侧面(即侧板21朝向弹簧片3的面)一体成型有凸条212，该凸条212与弹簧片3中部开设的狭缝31对应，并将插入的两根外导线隔开。可以采用将所述侧板21局部切口并折弯的方式形成所述凸条212，凸条212的凸起高度易于调控，确保凸条212的凸起高度充足，隔离性好。此外，所述侧板21也可以采用冲压的方式形成所述凸条212。所述凸条212不仅使本发明的引出件2的结构、安装工序更为简单，成本更低，还使得本发明免于额外设置隔板即可保证两根外导线分别具有独立的安装空间，避免外导线插入时可能滑到弹簧片3的中间狭缝处，导致不能被弹簧片3有效压接的问题，也避免了由于外导线相互干扰引起的连接不安全的问题。
本实施例中，所述侧板21内侧面设有向下倾斜的两斜块213，该两斜块213位于所述凸条212的两侧，两根外导线分别一一压向插入该两斜块213的底端，从而提高两根外导线的抗拔出能力。
所述底座1的数量为至少两个，该至少两个底座1结构相同，并拼接在一起，具体，相邻底座1之间通过拼接轴与拼接孔插接配合的方式进行拼接。本实施例中，所述底座1的数量具体为两个，但不局限于此，在其它实施例中，所述底座的数量为一个或多于两个。两个底座1结构基本相同，并基本对称。
如图6所示，两个底座1的相对内侧面，一个设有拼接轴15，另一个则设有拼接孔16，拼接轴15与拼接孔16插接配合。每个底座1上的引出件2、弹簧片3、输入夹簧4、内导线5的数量均为多个，并一一对应。因此，本发明既适用于两路的继电器(仅采用其中一个底座1)，也适用于四路的继电器(采用两个底座1)，并且，当底座1的数量进一步增加时，本发明还适用于更多路的继电器。
本实施例中，如图7所示，本发明还包括外壳6，该外壳6罩住拼接在一起的两个底座1。
本发明的一种直插式继电器插座，其采用激光熔焊代替焊接工艺实现内导线5与引出件2的内接部分、输入夹簧4电连接，能够避免引入焊接污染，同时较好地保护了输入夹簧4、引出件2的原有形貌及属性。
本发明的一种直插式继电器插座，未涉及部分均与现有技术相同或可采用现有技术加以实现。
此外，现有的继电器插座的输入夹簧和/或引出件普遍采用卡接的方式与导线连接，连接时，导线从输入夹簧/引出件设置的卡接口较宽的一端推入，并从卡接口较窄的一端伸出，同时被卡接口较窄的一端卡住。这种卡接口仅实现单向限位，使得导线在推入方向上不防松，因而其与导线的连接不够可靠。
针对以上所述的结构件与导线连接不可靠的问题，本发明还提供一种连接可靠的结构件及使用该结构件的继电器插座。
根据本发明的一个方面，一种连接可靠的结构件，包括可导电的本体，该本体设有用于与内导线电连接的卡接单元。所述卡接单元形成用于卡住所述内导线并供所述内导线侧向压入的第一卡接口、第二卡接口，第一卡接口的口径从第一卡接口向第二卡接口的方向渐大，第二卡接口的口径从第二卡接口向第一卡接口的方向渐大；或者，第一卡接口的口径从第一卡接口向第二卡接口的方向渐小，第二卡接口的口径从第二卡接口向第一卡接口的方向渐小。
根据本发明的一个实施例，所述卡接单元包括间隔分布的至少两个第一悬臂和间隔分布的至少两个第二悬臂，至少两个第一悬臂之间形成所述第一卡接口，至少两个第二悬臂之间形成所述第二卡接口。
根据本发明的一个实施例，所述第一悬臂与所述第二悬臂一一对应，各第一悬臂与相应的第二悬臂之间分别连接有一连接部，该连接部连接于所述本体。
根据本发明的一个实施例，所述第一悬臂和第二悬臂的数量均为两个，两个第一悬臂相对设置，两个第二悬臂相对设置。
根据本发明的一个实施例，所述第一卡接口、第二卡接口为上下排列。
根据本发明的一个实施例，所述本体包括基板，所述卡接单元设置于该基板。
根据本发明的一个实施例，所述结构件还包括设置于所述基板的一对簧片。
根据本发明的一个实施例，所述结构件还包括一端部相互连接的侧板和底板，所述底板与所述基板连接在一起。
根据本发明的一个方面，一种继电器插座，包括底座、输入夹簧、引出件和内导线。所述输入夹簧、所述引出件分别设置在底座中，所述内导线的两端分别与所述输入夹簧和所述引出件电连接。所述输入夹簧和/或引出件具有如本发明所述的连接可靠的结构件的卡接单元，并通过第一卡接口、第二卡接口卡住所述内导线。
根据本发明的一个实施例，继电器插座还包括弹簧片，该弹簧片设置于所述底座中，并与引出件配合，以将插入的外部导线压紧于所述引出件。
相较于现有技术中的结构件，本发明具有以下有益效果：
1、由于卡接单元形成用于卡住同一根内导线并供内导线侧向压入的第一卡接口、第二卡接口，第一卡接口的口径从第一卡接口向第二卡接口的方向渐大，第二卡接口的口径从第二卡接口向第一卡接口的方向渐大；或者，第一卡接口的口径从第一卡接口向第二卡接口的方向渐小，第二卡接口的口径从第二卡接口向第一卡接口的方向渐小，使得本发明的第一卡接口和第二卡接口能够对内导线实现双向限位，形成互锁，限制导线被拉动或被推动，从而使结构件牢牢卡住导线。此外，本发明的卡接单元利用两个卡接口(即第一卡接口和第二卡接口)卡住导线，与现有技术采用单卡接口的方式相比，本发明的卡接点成倍增加，使结构件与导线电连接更可靠。
2、所述卡接单元优选包括所述至少两第一悬臂、至少两第二悬臂，采用相对设置的至少两第一悬臂形成所述第一卡接口，采用相对设置的至少两第二悬臂形成所述第二卡接口，不仅有利于节约材料成本，还有利于提高卡接效果，并使卡接单元的结构更为简单、易于生产。
以下结合附图及实施例对本发明作进一步详细说明；但本发明的一种连接可靠的结构件及继电器插座不局限于实施例。
请参见图8至图10所示，本发明的一种连接可靠的结构件，包括可导电的本体41，该本体41设有用于与内导线5电连接的卡接单元42。该卡接单元42形成用于卡住同一根内导线5并供内导线5侧向压入的第一卡接口421、第二卡接口422。第一卡接口421的口径从第一卡接口421向第二卡接口422的方向渐大，第二卡接口422的口径从第二卡接口422向第一卡接口421的方向渐大。但不局限于此，在其它实施例中，第一卡接口的口径从第一卡接口向第二卡接口的方向渐小，第二卡接口的口径从第二卡接口向第一卡接口的方向渐小。第一卡接口421、第二卡接口422具体为上下排列的关系，但不局限于此，在其它实施例中，第一卡接口、第二卡接口为左右排列关系或前后排列关系等。所述侧向是指与第一卡接口421/第二卡接口422的中心线垂直的方向。
本实施例中，如图9所示，所述卡接单元42包括相对布置例如沿所卡住的内导线5周向间隔分布的至少两第一悬臂423和相对布置例如沿所卡住的内导线5周向间隔分布的至少两第二悬臂424，至少两第一悬臂423之间形成所述第一卡接口421，至少两第二悬臂424之间形成所述第二卡接口422。具体的，所述第一悬臂423和第二悬臂424的数量均为两个。由于第一卡接口421、第二卡接口422为上下排列关系，因而，两第一悬臂423、两第二悬臂424也为上下排列关系，且两第一悬臂423左右相对，两第二悬臂424左右相对。同时，两第一悬臂423之间形成的第 一卡接口421类似倒置的V字形，两第二悬臂424之间形成的第二卡接口422类似V字形。第一卡接口421的口径即为两第一悬臂423之间的间距，第二卡接口422的口径即为两第二悬臂424之间的间距。
本实施例中，所述第一悬臂423与所述第二悬臂424在上下方向上一一对应，各第一悬臂423与相应的第二悬臂424之间分别连接有一连接部425，该连接部425后端连接(连接包括一体相连接或其它非一体相连的形式)于所述本体41。位于同一侧的第一悬臂423、所述第二悬臂424和连接部425可以为一整体结构。所述连接部425使各第一悬臂423与相应的第二悬臂424更便于与本体41连接。
本实施例中，所述本体41包括竖向基板411，所述卡接单元42设置于该基板411：各第一悬臂423与相应的第二悬臂424之间的连接部425分别连接于基板411的左右两侧面，使各第一悬臂423、第二悬臂424位于基板411的前侧。例如，所述连接部425可以由基板411延伸出来，且可以与基板411成90°夹角，各第一悬臂423、第二悬臂424由相应的连接部425延伸出来，且可以与连接部425约成45°夹角。
本实施例中，所述本体41还包括一对簧片412，其设于所述基板411顶部。所述基板411的左右两侧面分别设有一限位凸台4111，两限位凸台4111左右相对，并位于簧片412和卡接单元42之间。
本发明中图8至图10所示出的连接可靠的结构件，可构成继电器插座的输入夹簧。如图10所示，连接内导线5(该内导线5可以为单股的硬质圆铜导线)时，将内导线5一端同时侧向(具体为向后侧方向)压入第一卡接口421和第二卡接口422。此时，两第一悬臂423顶端在结构件固有弹力的作用下嵌入内导线5，且其与内导线5的接触段宽度为D，同时，两第二悬臂424底端在结构件固有弹力的作用下也嵌入内导线5，且其与内导线5的接触段宽度也为D。因而，本发明能够在上下方向上对导线实现双向限位，形成互锁，限制导线被拉动或被推动，从而使结构件牢牢卡住导线。此外，本发明的结构件利用两个卡接口(即第一卡接口421和第二卡接口422)卡住导线，与现有技术采用单卡接口的方式相比，本发明的卡接点成倍增加，使结构件与导线电连接更可靠。
请参见图11，本发明的一种连接可靠的结构件，其与上述图8至图10所示的结构件的区别在于：结构件还包括侧板21和底板22，侧板21和底板22的一端相互连接或一体成型形成L形；本体41的基板411上不设置簧片412；底板22与所述基板411顶端连接在一起。具体的，底板22设有L形缺口223，所述基板411及其上的卡接单元42位于该L形缺口133中。
本发明图11的连接可靠的结构件，可构成继电器插座的引出件，所述侧板21的顶端部设有向外倾斜延伸的限位块211，用于整个结构件的安装限位。所述侧板21内侧顶部设有向下倾斜延伸的斜块213，用于提高插入的外部导线的抗拔能力。 所述侧板21的内侧面还可以进一步设置凸条，用于将插入的两根外部导线隔开。
本发明的连接可靠的结构件，其第一卡接口421、第二卡接口422同样能够在上下方向上对内导线5实现上下限位，形成互锁，从而限制内导线5被拉动或被推动。
请参见图12和图13所示，本发明的一种继电器插座，包括底座1、输入夹簧4、引出件2、内导线5。输入夹簧5、引出件2分别装在底座1中，内导线5为单股的硬质圆铜导线，其两端分别与输入夹簧5、引出件2电连接；输入夹簧4和/或引出件2具有如上述图8至图10实施例或者图11实施例二中所述的卡接单元42，并通过其第一卡接口421、第二卡接口422卡住内导线5。具体的，输入夹簧5采用上述图8至图10实施例所述的连接可靠的结构件；引出件2采用上述图11实施例所述的连接可靠的结构件。
本实施例中，本发明还包括弹簧片7，该弹簧片7设置于所述底座1中，并与引出件2配合，以将插入的外部导线压紧于所述引出件2的侧板21，如此，使本发明的继电器插座构成一种直插式继电器插座。
本实施例中，参考图6和图7，所述底座1的数量为至少两个，该至少两个底座1结构相同，并拼接在一起，具体，相邻底座1之间通过拼接轴与拼接孔插接配合的方式进行拼接。本实施例中，所述底座1的数量具体为两个，但不局限于此，在其它实施例中，所述底座的数量为一个或多于两个。两个底座1结构基本相同，并基本对称。
如图6所示，两个底座1的相对内侧面，一个设有拼接轴15，另一个则设有拼接孔16，拼接轴15与拼接孔16插接配合。每个底座1上的引出件2、弹簧片3、输入夹簧4、内导线5的数量均为多个，并一一对应。因此，本发明既适用于两路的继电器(仅采用其中一个底座1)，也适用于四路的继电器(采用两个底座1)，并且，当底座1的数量进一步增加时，本发明还适用于更多路的继电器。
本实施例中，如图7所示，本发明还包括外壳6，该外壳6罩住拼接在一起的两个底座1。
本发明的继电器插座，输入夹簧4、引出件2分别采用前面所述的第一卡接口21、第二卡接口22卡住内导线5，能够形成互锁，限制内导线5被拉动或被推动，使输入夹簧4、引出件2与内导线5之间的电连接更可靠。
此外，现有的继电器插座的引出部分一般包括引出件、弹簧片和隔板，隔板竖向嵌入弹簧片和引出件，并将插入的两根外导线隔开。隔板使插入的两根外导线分别具有一个独立的安装空间，但设置隔板，使得继电器插座的结构、安装工序更为复杂，成本较高。为了节约成本，不少继电器插座取消了隔板，但两根相互靠近的外导线插入时可能滑到弹簧片的中间狭缝处，导致不能被弹簧片有效压接；并且，各外导线插入时容易滑到另一根外导线处，从而干扰另一根外导线的电连接。
针对现有的外导线连接结构存在的技术问题，本发明还提供一种结构简单、成本低的继电器插座的外导线连接结构及直插式继电器插座。
根据本发明的一个方面，一种继电器插座的外导线连接结构，包括底座、引出件和弹簧片。所述引出件和所述弹簧片分别设置于所述底座设置的第一容腔和第二容腔中，所述引出件包括内接部分和外接部分，所述弹簧片与所述外接部分配合，以将插入的两根外导线压紧于所述外接部分。所述外接部分一体成型有凸条，该凸条与所述弹簧片开设的狭缝对应，并将插入的所述两根外导线隔开。
根据本发明的一个实施例，所述外接部分为一侧板，该侧板底端与所述内接部分一体相连，该侧板内侧面设置所述凸条。
根据本发明的一个实施例，所述侧板通过冲压形成所述凸条；或者，所述侧板通过局部局部切口并折弯形成所述凸条。
根据本发明的一个实施例，所述侧板内侧面设有向下倾斜的两个斜块，该两个斜块位于所述凸条的两侧，该两个斜块底端分别一一压向插入的所述两根外导线。
根据本发明的一个实施例，所述侧板顶端设有限位部，该限位部卡入所述容腔侧壁对应设置的第一限位槽中。
根据本发明的一个实施例，所述限位部包括若干相互间隔的限位块，各限位块分别向所述侧板外侧倾斜延伸。
根据本发明的一个实施例，所述内接部分为一底板，该底板设有夹口，且该底板一端与所述侧板底端相连，该底板另一端顶面和/或底面设有凸部，底板端部及该凸部置入所述容腔侧壁底部对应设置的第二限位槽，并呈过盈配合。
根据本发明的一个实施例，所述底座顶部设有与所述引出件对应并供所述两外导线插入的插孔组，该插孔组包括两个导线插孔，该两个导线插孔彼此相互间隔，并连接所述第一容腔。
根据本发明的一个实施例，所述弹簧片呈倒置的V字形，且其一边抵于所述第一容腔的侧壁，另一边与所述外接部分配合，并开设所述狭缝。
根据本发明的另一个方面，一种直插式继电器插座，包括输入夹簧、内导线和如本发明所述的继电器插座的外导线连接结构，所述输入夹簧设置于所述底座中，并通过内导线与所述引出件的内接部分电连接。
相较于现有技术的外导线连接结构，本发明具有以下有益效果：
1、由于外接部分一体成型有凸条，该凸条与弹簧片开设的狭缝对应，并将插入的两根外导线隔开，使得本发明免于设置隔板，即可保证两根外导线分别具有独立的安装空间，避免外导线插入时可能滑到弹簧片的中间狭缝处，导致不能被弹簧片有效压接，也避免了由于外导线相互干扰引起的连接不安全的问题。与设置隔板的继电器插座相比，显然，本发明的结构、安装工序更为简单，成本更低。
2、所述凸条优选可以采用将引出件的外接部分局部切口并折弯的工艺形成，使 凸条的凸起高度易于调控，确保凸条的凸起高度充足，隔离性好。
3、所述侧板顶端设有限位部，该限位部卡入所述容腔侧壁对应设置的第一限位槽中，能够对引出件横向提供限位，避免引出件出现横向晃动，从而提高引出件的抗冲击能力，提高本发明工作的稳定性。特别的，所述限位部包括若干相互间隔的限位块，各限位块分别向所述侧板外侧折弯，不仅使限位块的形成工艺更为简单，还可以对外导线进行避让，避免限位块对外导线的插入造成干涉。
4、所述凸部的设置，能够对引出件竖向提供限位，避免引出件出现竖向晃动，从而提高引出件的抗冲击能力，提高本发明工作的稳定性。
以下结合附图及实施例对本发明作进一步详细说明；但本发明的一种继电器插座的外导线连接结构及直插式继电器插座不局限于实施例。
请参见图14至图20所示，本发明的一种继电器插座的外导线连接结构，包括底座1、引出件2和弹簧片3。底座1具有第一容腔11和第二容腔12。引出件2和弹簧片3分别安装于底座1设置的第一容腔11和第二容腔12中。引出件2包括内接部分和外接部分。弹簧片3与外接部分配合，以将插入的两根外导线压紧于外接部分。弹簧片3上设有长条形狭缝31。外接部分内侧面一体成型有凸条212，该凸条212与弹簧片3中部开设的狭缝31对应，并将插入的两根外导线隔开。所述内接部分即指引出件2用于与继电器插座的输入夹簧电连接的部分，所述外接部分的内侧面是指外接部分朝向弹簧片3的一个侧面，相应的，外接部分背离弹簧片3的一个侧面为外接部分的外侧面。
本实施例中，如图15、图16所示，所述外接部分为一侧板21，该侧板21底端与所述内接部分相连，或者侧板21底端与所述内接部分为一整体结构。该侧板21内侧面设置所述凸条212。可以通过将所述侧板21局部局部切口并折弯形成所述凸条212，使所述凸条212的凸起高度h易于调控，确保凸条212的凸起高度充足，隔离性好。在其它实施例中，所述侧板21通过冲压形成所述凸条212，如图23所示。
本实施例中，如图17、图18所示，所述弹簧片3大致呈倒置的V字形，且其一边抵于所述容腔11侧壁，另一边与所述外接部分配合，并在中部位置开设所述狭缝31。所述弹簧片3中部开设的狭缝31呈长条形，从而将所弹簧片3另一边分成两个弹性臂。所述凸条212的宽度C略小于所述弹簧片3的狭缝31的宽度D，使凸条212可以卡入弹簧片3的狭缝31的端部内。所述第一容腔11中设有一支轴14，所述弹簧片3拐弯部位呈圆弧状，并绕过该支轴14。
本实施例中，所述侧板21内侧面设有向下倾斜的两斜块213，该两斜块213位于所述凸条212相对的两侧，该两斜块213底端分别一一压向插入的两根外导线，从而提高两根外导线的抗拔出能力。
本实施例中，所述侧板21顶端设有限位部，该限位部卡入所述第一容腔11侧壁顶部设置的第一限位槽111中。具体的，所述限位部包括两个相互间隔的限位块 211，各限位块211分别向所述侧板21外侧向上倾斜延伸。
本实施例中，所述内接部分为一底板22，该底板22设有夹口221，且该底板22一端与所述侧板21底端一体相连，该底板22另一端顶面设有凸部222，凸部222也可以设置于底板22的底面，或者底板22的底面和顶面同时设置凸部222。。底板22另一端部及凸部222设置于所述第一容腔11底部对应设置的第二限位槽112，并呈过盈配合。上述限位块211、凸部222共同配合，将引出件2牢牢定位在底座1的第一容腔11中，从而提高本发明的引出件的抗冲击能力，提高本发明工作的稳定性。
本实施例中，所述底座1顶部设有与所述引出件2对应并供所述两外导线插入的插孔组，该插孔组包括两个导线插孔18，该两个导线插孔18彼此相互间隔，并通向所述第容腔11。所述底座1上罩设有外壳6，该外壳6设有与所述导线插孔对应的外插孔61。
本发明的一种继电器插座的外导线连接结构，如图20所示，插接外导线7(该外导线7为硬质导线或带硬质套管的导线)时，将外导线7端部从外壳6的外插孔61、底座1的导线插孔18依次插入，并进入底座1第一容腔11中，如图19所示。随着外导线7端部继续向下运动，外导线7端部触及弹簧片3，并推动弹簧片3向下摆动形成让位，待外导线7端部插入到位后，弹簧片3弹性复位，并对外导线7施加向左的弹力F，使外导线7紧贴引出件2的侧板21，图20从而实现外导线与引出件2的电连接。插入的两根外导线7由侧板21内侧面的凸条212隔开，保证两根外导线7分别具有独立的安装空间，避免外导线7插入时可能滑到弹簧片3的中间狭缝31处，导致不能被弹簧片3有效压接，也避免了由于外导线7相互干扰引起的连接不安全。与现有技术设置隔板的继电器插座相比，显然，本发明的结构、安装工序更为简单，成本更低。
请参见图21、图22所示，本发明一种直插式继电器插座，包括输入夹簧4、内导线5，还包括上述本发明所述的继电器插座的外导线连接结构。输入夹簧4安装于所述底座1中，并通过内导线5与所述引出件2的内接部分(即所述底板22)电连接。
本实施例中，所述内导线5两端分别卡入所述底板22和输入夹簧4设置的夹口221、40中，并通过激光熔焊的工艺进一步固定，如此，能够避免引入焊接污染，同时较好地保护了输入夹簧4、引出件2的原有形貌及属性。
图18图20本实施例中，所述输入夹簧4、内导线5、引出件2、弹簧片3的数量分别为多个，并一一对应。
本发明的继电器插座的外导线连接结构及直插式继电器插座，未涉及部分均与现有技术相同或可采用现有技术加以实现。
