具体实施方式
为了更好地理解本申请的技术方案,下面结合附图对本申请实施例进行详细描述。
应当明确,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
传感装置包括检测组件和壳体5,例如图2所示。检测组件用于对气体、环境温度等进行检测,壳体5对检测组件起保护作用,以减少外力导致的检测组件的变形。检测组件包括检测元件1、引出电极2和导电端子3,引出电极2的一端与导电端子3连接,引出电极2的另一端与检测元件1连接,例如图1所示。相关技术中,沿导电端子3的延伸方向Z,引出电极2的至少部分凸出于导电端子3设置,例如图1中引出电极2所示。引出电极2为柔性部件,在外力作用下容易发生变形。例如图2所示,在检测组件与壳体5组装的过程中,凸出于导电端子3设置的检测元件1和引出电极2首先进入壳体5内腔,与壳体5内壁发生碰撞后,引出电极2 发生扭曲和折弯。引出电极2的变形不仅会影响检测信号的传输,而且容易导致其与检测元件1或导电端子3的连接失效。此外,由于引出电极2凸出于导电端子3的一端设置,检测组件整体较高,不利于传感装置整体的小型化。
为此,本申请的第一方面提供一种检测组件100,以减少引出电极在外力作用下发生变形。本申请的检测组件100包括检测元件1、引出电极2和导电端子3,引出电极2与导电端子3电性连接,并且引出电极2与检测元件1电性连接,例如图3所示。检测元件1的检测信号通过引出电极2传输至导电端子3,并通过导电端子3传输至检测电路。
本申请提供七种实施方式的检测组件100,例如图3~8所示为第一种实施方式的示意图,例如图9~11所示为第二种实施方式的示意图,例如图12~16所示为第三种实施方式的示意图,例如图17和图18所示为第四种实施方式的示意图,例如图19所示为第五种实施方式的示意图,例如图20所示为第六种实施方式的示意图,例如图21和图22所示为第七种实施方式的示意图。
导电端子3为刚性部件,其不仅用于传输信号,还对引出电极2起支撑作用,使引出电极2竖立设置,进而使检测元件1与被检测物质充分接触,或者使检测元件1充分暴露在被检测环境中。
检测组件100包括至少一对引出电极2。一对引出电极2的形状、结构和尺寸可以相同或不同。例如图3和图4所示,检测组件100包括形状、结构和尺寸都相同的第一引出电极21和第二引出电极22,第一引出电极21和第二引出电极22构成一对引出电极2。
检测组件100还包括至少一对导电端子3,一对导电端子3的形状、结构和尺寸可以相同或不同。例如图3~图5所示,检测组件100包括形状、结构和尺寸都相同的第一导电端子31和第二导电端子32,第一导电端子31和第二导电端子32构成一对导电端子3。第一导电端子31和第二导电端子32均为柱状,例如圆柱状。
例如图3~图5所示,第一导电端子31具有第一端部311和第二端部312。沿导电端子3的延伸方向Z,第一导电端子31的第一端部311和第二端部312分别位于第一导电端子31的两端。第一导电端子31的第一端 部311与第一引出电极21连接,第一导电端子31的第二端部312用于与检测电路连接,第一导电端子31的第一端部311具有第一末端313,第一导电端子31的第二端部312具有第二末端314。沿导电端子3的延伸方向Z,第一引出电极21与第一导电端子31的第一端部311位于第一导电端子31的第二末端314的相同侧。第二导电端子32具有第一端部321和第二端部322。沿导电端子3的延伸方向Z,第二导电端子32的第一端部321和第二端部322分别位于第二导电端子32的两端。第二导电端子32的第一端部321与第二引出电极22连接,第二导电端子32的第二端部322用于与检测电路连接,第二导电端子32的第一端部321具有第一末端323,第二导电端子32的第二端部322具有第二末端324。沿导电端子3的延伸方向Z,第二引出电极22与第二导电端子32的第一端部321位于第二导电端子32的第二末端324的相同侧。在本申请的一些实施方式中,检测组件100的高度方向与导电端子3的延伸方向Z同向。
在一些实施方式中,第一导电端子31的第一末端313、第一导电端子31的第二末端314、第二导电端子32的第一末端323和第二导电端子32的第二末端324分别可以是端面,例如,平面、曲面或粗糙面。或者,当第一端部311、321,或者第二端部312、322呈锥形时,第一末端313、323呈点状,或者,第二末端314、324呈点状。
为了减少引出电极2在外力作用下产生的变形,本申请对引出电极2与导电端子3的相对位置进行设计。下面以第一引出电极21和第一导电端子31的相对位置为例进行说明。
第一引出电极21包括第一连接部211和第一延伸部212,第一连接部211与第一导电端子31的第一端部311连接,第一延伸部212自第一连接部211向远离第一导电端子31的方向延伸,例如图3~图6所示。
在一些实施方式中,沿导电端子3的延伸方向Z,第一连接部211与第一导电端子31的第二端部312位于第一导电端子31的第一末端313的相同侧,例如图3~图6示,或者图21所示,或者图9~图11所示。第一端部311具有侧面315,第一连接部211与侧面315连接,如图4和图6所示。由于第一导电端子31的直径较小,而第一导电端子31的侧面315具有较大的面积,因此第一连接部211与第一导电端子31的侧面315连 接,有利于降低第一引出电极21与第一导电端子31的连接难度。如此,在导电端子3的延伸方向上,第一连接部211既不凸出于第一末端313,也不凸出于第二末端314,能够利用第一导电端子31为第一连接部211阻挡外力,减少第一连接部211的在外力作用下的变形。
第一延伸部212的至少部分与第一导电端子31的第二端部312位于第一导电端子31的第一末端313的相同侧,例如图26所示。如此,减少了检测组件100的高度方向上,第一引出电极21从第一导电端子31的第一末端313向外凸伸部分的高度,也即降低了第一延伸部212的高度,从而降低了检测组件100的高度。
在另一些实施方式中,沿导电端子3的延伸方向Z,第一连接部211与第一导电端子31的第二端部312分别位于第一导电端子31的第一末端313的不同侧,并且第一连接部211位于与导电端子的延伸方向垂直的平面内,例如图12~图15所示,或者图17和图18所示。第一连接部211与第一末端313连接,第一连接部211略高于第一末端313,并且大致与第一末端313齐平。此时,沿导电端子的延伸方向Z,第一连接部211的顶部A1与第一末端313的高度之差,大致等于第一连接部211在垂直于检测组件100高度方向上的厚度,如图13和图14所示。如此,也能够减少第一连接部211在外力作用下的变形。
在一些实施方式中,沿导电端子3的延伸方向Z,第一延伸部212与第一导电端子31的第二端部312位于第一导电端子31的第一末端313的相同侧,例如图3~图6示,或者图9~图11所示。如此,在导电端子的延伸方向上,第一延伸部212既不凸出于第一末端313,也不凸出于第二末端314,在检测组件100与外界物质发生碰撞时,第一导电端子31能够为第一延伸部212阻挡一部分外力,从而减少第一延伸部212的变形。
在另一些实施方式中,第一延伸部212与第一导电端子31的第二端部312分别位于第一导电端子31的第一末端313的不同侧,并且第一延伸部212位于与导电端子的延伸方向垂直的平面内,例如图12~图15所示,或者图17和图18所示。第一延伸部212略高于第一末端313,并且大致与第一末端313齐平。此时,沿导电端子的延伸方向,第一延伸部212的顶部A2与第一末端313的高度之差,大致等于第一延伸部212在垂直于 检测组件100高度方向上的厚度。如此,也能够减少第一延伸部212在外力作用下的变形。
在本申请中,沿导电端子3的延伸方向Z,无论是第一引出电极21不高于第一导电端子31的第一末端313,还是第一引出电极21略高于第一导电端子31的第一末端313,都能够减少第一引出电极21在外力作用下产生的变形。而且,还能够减小检测组件100的整体高度,有利于检测组件100的小型化。
在一些实施方式中,沿导电端子3的延伸方向Z,第一连接部211和第一延伸部212分别位于第一导电端子31的第一末端313的不同侧。例如图19所示,第一连接部211与第一导电端子31的第一末端313连接,沿导电端子3的延伸方向Z,第一连接部211与第一导电端子31的第二端部312分别位于第一导电端子31的第一末端313的不同侧,并且第一连接部211位于与导电端子的延伸方向垂直的平面内;沿导电端子3的延伸方向Z,第一延伸部212与第一导电端子31的第二端部312位于第一导电端子31的第一末端313的相同侧。又例如图20所示,沿导电端子3的延伸方向Z,第一连接部211与第一导电端子31的第二端部312位于第一导电端子31的第一末端313的相同侧,第一延伸部212与第一导电端子31的第二端部312分别位于第一导电端子31的第一末端313的不同侧,并且第一延伸部212位于与导电端子的延伸方向垂直的平面内。
在另一些实施方式中,沿导电端子3的延伸方向Z,第一连接部211和第一延伸部212位于第一导电端子31的第一末端313的相同侧,例如图3~图6示,或者图9~图11所示。沿导电端子3的延伸方向Z,第一引出电极21的第一连接部211和第一延伸部212与第一导电端子31的第二端部312位于第一导电端子31的第一末端313的相同侧。例如图12~图15所示,或者图17~图19所示,沿导电端子3的延伸方向Z,第一引出电极21的第一连接部211和第一延伸部212与第一导电端子31的第二端部312分别位于第一导电端子31的第一末端313的不同侧,并且第一引出电极21位于与导电端子的延伸方向垂直的平面内。相对于第一连接部211和第一延伸部212分别位于第一导电端子31的第一末端313的不同侧的方案,第一连接部211和第一延伸部212位于第一导电端子31的第一 末端313的相同侧能够减少第一引出电极21的弯折或扭曲,从而减少第一引出电极21内部应力对信号传输的影响。
同样地,第二引出电极22包括第二连接部221和第二延伸部222,第二连接部221与第二导电端子32的第一端部321连接,第二延伸部222自第二连接部221向远离第二导电端子32的第一端部321的方向延伸,例如图3~图6示。与第一引出电极21与第一导电端子31的相对位置相同,本申请对第二引出电极22与第二导电端子32的相对位置进行相同的设置,在此不再赘述。
在一些实施方式中,第一延伸部212位于第一导电端子31朝向第二导电端子32的一侧,第二延伸部222位于第二导电端子32朝向第一导电端子31的一侧。例如图3~图6所示,或者,例如图21所示,或者如图9~图11所示,在第一导电端子31中心和第二导电端子32中心的连线方向上,第一延伸部212与第二导电端子32位于第一导电端子31的相同侧,第二延伸部222与第一导电端子31位于第二导电端子32的相同侧,也就是说,第一延伸部212和第二延伸部222位于第一导电端子31和第二导电端子32之间。如此,使得第一导电端子31和第二导电端子32能够为第一延伸部212和第二延伸部222阻挡外力,减少第一延伸部212和第二延伸部222在外力作用下的变形。
引出电极2可以薄膜状、片状或线状。引出电极2弯折会导致内应力增加,进而影响电信号在引出电极2内的传输。因此,在一些实施方式中,引出电极2位于平面内,所述平面与导电端子的延伸方向平行,例如图3~图6所示;或者,所述平面与导电端子的延伸方向垂直,例如图12~图15所示。如此,能够减少引出电极2的弯折。当然,在实际中,由于检测元件或引出电极的自重或者其他原因可能导致引出电极2稍微偏离平面,或者使其并不完全位于平面内,这种情况在本申请中仍视作引出电极2位于或大致位于平面内。

在一些实施方式中,第一引出电极21与第二引出电极22齐平。也就是说,第一引出电极21与第二引出电极22位于相同的平面内,该平面例如可以是与导电端子的延伸方向垂直或平行。如此,能够减少第一引出电极21与第二引出电极22之间的相互影响。由于第一引出电极21与第二引出电极22均与检测元件1连接,若第一引出电极21与第二引出电极22不齐平,第一引出电极21和第二引出电极22中的至少一个需要弯折。如前所述,引出电极弯折会导致内应力产生,影响电信号的传输。因此,将第一引出电极21与第二引出电极22设置为齐平,能够减少引出电极中内应力的产生。当然,在实际中,由于检测元件或引出电极的自重或者其他原因可能导致第一引出电极21与第二引出电极22稍微偏离“齐平”的位置,这种情况在本申请中仍视作第一引出电极21与第二引出电极22齐平或大致齐平。

同样地,对于第二引出电极22而言,第二引出电极22位于与导电端子的延伸方向平行的平面内,第二引出电极22与第二导电端子32的侧面 325连接,例如图3~图6所示。第二连接部221具有第一连接端2211和第二连接端2212,第一连接端2211和第二连接端2212分别位于第二连接部221沿检测组件100的高度方向或者宽度方向的两端。第二连接部221的第一连接端2211相对于第二连接部221的第二连接端2212靠近第二导电端子32的第一末端323。第二连接部221具有与第二延伸部222连接的第二连接处2213,第二连接处2213可以位于第二连接部221的第一连接端2211,例如图3~图6所示;或者,第二连接处2113可以位于第二连接端2212,例如图9~图11所示,或者例如图22所示;或者,第二连接处2113也可以位于第一连接端2211和第二连接端2212之间的任意位置。
在一些实施方式中,第一连接部211和第二连接部221具有相同的形状、结构和尺寸。在一些实施方式中,第一连接部211与第二连接部221对称设置。例如图3、图7和图8所示。第一连接部211和第二连接部221均为薄片状,第一连接部211和第二连接部221均呈条状,在图12~图15中,第一连接部211和第二连接部221均为圆形。在图3~图8中,或者,在图9~图11中,或者图17和图18中,第一连接部211与第二连接部221轴对称设置;在图12~图15中,第一连接部211与第二连接部221中心对称设置。
相关技术中,引出电极2与导电端子3之间通过点焊的方式连接。点焊连接的可靠性较差,引出电极2与导电端子3容易在连接处分离,造成连接失效。
在一些实施方式中,连接部包括用于与导电端子3连接的连接区域23,连接区域23呈线状或面状。以第一引出电极21与第一导电端子31的连接为例。当第一连接部211的连接区域23呈线状时,例如图8所示,第一连接部211与第一导电端子31之间的连接为线连接;当第一连接部211的连接区域23呈面状时,第一连接部211与第一导电端子31之间的连接为面连接。同样的,当第二连接部221的连接区域23呈线状时,例如图8所示,第二连接部221与第二导电端子32之间的连接为线连接;当第二连接部221的连接区域23呈面状时,第二连接部221与第二导电端子32之间的连接为面连接。
为了判断连接区域的形状,可以将引出电极2与导电端子3分离,如 果引出电极2与导电端子3分离后在引出电极2或导电端子3上留下线状的连接痕迹,则说明引出电极2与导电端子3的连接处呈线状;如果引出电极2与导电端子3分离后在引出电极2或导电端子3上留下面状的连接痕迹,则说明引出电极2与导电端子3的连接处呈面状。
为了实现信号传输,引出电极2不仅要与导电端子3连接,还要与检测元件1连接。检测元件1包括检测部11和至少一对电极部12。检测部11与电极部12电连接,并且电极部12与引出电极2电连接,例如图16所示。检测部11能够在被检测物质或被检测参数的影响下产生电信号,例如,在气体浓度发生变化时产生电信号,电信号通过电极部12传输至引出电极2,并通过导电端子3传输至检测电路。
在一些实施方式中,检测元件1包括绝缘基板13,检测部11是覆设于绝缘基板13表面的热敏电阻材料,电极部12是覆设于绝缘基板13表面的导电层,例如图16所示。当气体浓度的变化导致热敏电阻材料所暴露的环境的温度发生变化时,热敏电阻材料的电阻发生变化,并由此产生电信号。电信号通过电极部12、引出电极2和导电端子3传输至检测电路。在一些实施方式中,第一引出电极21和第二引出电极22所在平面与检测元件1的至少部分表面平行。例如,与检测元件的电极部平行。如此,能够减少引出电极与检测元件连接导致的引出电极的变形。
在一些实施方式中,引出电极2所在的平面与绝缘基板13平行。如此,能够减少引出电极2与检测元件1连接导致的引出电极2的弯折,例如图16所示。

在一些实施方式中,底座4的外径小于壳体5的内径。如此,壳体5能够盖设在底座4的外围。
在一些实施方式中,底座4具有第一中心轴线L1,壳体5具有第二中心轴线L2。第一中心轴线L1与第二中心轴L2线重合,例如图29所示。如此,检测组件100能够位于壳体5中央。
在一些实施方式中,传感装置具有第一腔501和第二腔502,第一腔501与传感装置的外界气体性连通,第一腔501为开放腔,第二腔502为封闭腔。检测组件100包括第一检测组件101和第二检测组件102,第一检测组件101至少部分位于第一腔501,第二检测组件103至少部分位于第二腔502。第二检测组件102作为第一检测组件101的参比组件,例如图27,用于对第一检测组件101的检测结果进行修正,提高检测精度。检测时,待检测气体进入开放腔,开放腔中气体的热导率发生变化,进而使第一检测组件101的热敏电阻的阻值发生变化。对应地,待检测气体无法进入封闭腔对第二检测组件102的热敏电阻的阻值产生影响。
相关技术中,由于第一检测组件101的壳体与第二检测组件102的壳体相连,进入开放腔的待检测气体所携带的热量/冷量非常容易通过壳体传导至第二检测组件102,使第二检测组件102的热敏电阻的阻值发生变化,影响其对检测结果的修正,进而降低检测精度。
为了减少第一检测组件101和第二检测组件102之间的相互影响,本申请对壳体5进行设计。壳体5包括第一壳体51和第二壳体52,第一壳体51位于第一腔501的外围,第二壳体52位于第二腔502的外围。第一壳体51和第二壳体52分别独立设置,第一壳体51与第二壳体52之间有间距。也即,第一壳体51和第二壳体52不具有共用的壁,例如图25和 图26所示。在另一些实施例中,也可以通过一个连接板将独立设置的第一壳体51和第二壳体52连接到一起。
在一些实施方式中,第一壳体51具有第一容腔511,第一容腔511的至少部分形成第一腔501,第一容腔511具有第一开口5001,第一开口5001气体性连通第一腔501和传感装置的外界,第二壳体52具有第二容腔521,第二容腔521的至少部分形成第二腔502。第一壳体51还具有第二开口5002,电路板6全面覆盖第二开口5002。沿第一壳体51的高度方向,第一开口5001和第二开口5002分别位于第一壳体51的两侧。
第二壳体52具有第三开口5003,第二壳体52具有位于第三开口5003外围的壁面,电路板6全面覆盖第三开口5003,并且沿传感装置的高度方向,壁面在电路板的投影位于电路板6的外轮廓之内。
在一些实施方式中,第一开口5001设置于第一壳体51的第三侧532,第二开口5002设置于第一壳体51的第四侧533,例如图28所示,第一壳体51具有第一侧壁5111,第一侧壁5111位于第三侧532,第一开口5001设于第一侧壁5111。第一壳体51的第四侧533与第一底座41焊接。沿导电端子3的延伸方向Z,位于第一壳体51的第二开口5002外围的周壁531在第一底座41的投影位于第一底座41的外轮廓之内。第三开口5003设于第二壳体52的第四侧533。第二壳体52具有第二侧壁5211,第二侧壁5211位于第二壳体52的第三侧532。第二壳体52的第四侧533与第二底座42焊接,且第二壳体52的第三侧532与第二底座42密封连接,第二壳体52与第二底座42形成封闭腔,也即封闭的第二腔502。沿检测组件的高度方向,位于第二壳体52的第三开口5003外围的周壁531在第二底座42的投影位于第二底座42的外轮廓之内。也就是说,第一底座41全面覆盖第一壳体51的第二开口5002,第二底座42全面覆盖第二壳体52的第三开口5003。
在一些实施方式中,第一壳体51和第二壳体52中的至少一者具有翻边部534。
底座4包括第一底座41和第二底座42,第一壳体51和第一底座41均位于第一腔501的外围,第一底座41的第一中心轴线L1贯穿第一开口5001。第二壳体52和第二底座42均位于第二腔502的外围,第二壳体52 与第二底座42密封连接;或者,电路板6位于第一腔501和第二腔502的外围,第一底座41位于第一腔501,第二底座42位于第二腔502,第二壳体52与电路板6密封连接。
第一检测组件101包括第一检测元件1011,第二检测组件102包括第二检测元件1021,例如图31,第一检测元件1011位于第一腔501,第二检测元件1021位于第二腔502。由于第一壳体51和第二壳体52分别独立设置,第一壳体51和第二壳体52不具有共用的侧壁,因而能够减少第一检测组件101与第二检测组件102之间的热量传递。
为了使第一检测组件101与第二检测组件102的检测环境趋于相同,第二检测组件102与第一检测组件101可以对称设置。
在一些实施方式中,第一检测组件101的高度方向与第二检测组件102的高度方向平行或同向。在一些实施方式中,第一检测组件101的对称轴与第二检测组件102的对称轴共线。在一些实施方式中,第一壳体51的轴线与第二壳体52的轴线共线。
第一检测组件101和第二检测组件102分别包括至少一对导电端子3,以及分别包括至少一对引出电极2。至少一对导电端子3包括第一导电端子31和第二导电端子32,至少一对引出电极2包括第一引出电极21和第二引出电极22,例如图26所示,第一导电端子31与第一引出电极21电连接,第二导电端子32与第二引出电极22电连接。第一检测元件1011与第一导电端子31和第二导电端子32电连接。第二检测元件1021与第一导电端子31和第二导电端子32电连接。
在一些实施方式中,至少一对引出电极21、22相对于第一中心轴线L1轴对称设置,至少一对导电端子31、32相对于第一中心轴线L1轴对称设置,检测元件1相对于第一中心轴线L1轴对称设置。
在检测过程中,气体通过设于第一壳体51的第一开口5001进入第一腔501,使第一检测组件101的检测元件1产生电信号的变化,例如电阻的变化。第二检测组件102作为第一检测组件101的参比组件,需要能够排除是否与待检测气体接触以外的其他环境因素对检测结果的影响。因此,在理想状态下,第一检测组件101和第二检测组件102处于相同的环境,也即除了是否与待检测气体接触以外,第一检测组件101和第二检测组件 102所受到的环境因素的影响大致相同。例如,外界气体分别与第一壳体51和第二壳体52接触,外界气体与第一壳体51接触所导致的第一壳体51的温度变化大致等于外界气体与第二壳体52接触所导致的第二壳体52的温度变化。如此,第一壳体51与第一检测组件101之间的热量传递所导致的第一检测组件101的电信号的变化大致等于第二壳体52与第二检测组件102之间的热量传递所导致的第二检测组件102的电信号的变化。
简单而言,对于第一检测组件101的检测元件和第二检测组件102的检测元件均为热敏电阻的情况,假设待测气体进入第一腔501导致的第一检测组件101的热敏电阻的阻值变化为R1,其他因素(例如,流动在第一壳体51之外的气体通过第一壳体51与第一检测组件101发生热传导,等等)导致的第一检测组件101的热敏电阻的阻值的变化为R2。如此,检测到第一检测组件101的热敏电阻的阻值变化为Rx,Rx=R1+R2。理想状态下,第二检测组件102与第一检测组件101处于相同的环境,因此,第二检测组件102的热敏电阻的阻值的变化Ry=R2。也就是说,第一检测组件101的检测环境与第二检测组件102的检测环境的差别在于,第一检测组件101的热敏电阻与待测气体接触,而第二检测组件102的热敏电阻与待测气体不接触,因此,除了“与待测气体接触”这一因素之外的其他因素导致的热敏电阻的阻值变化都应该体现在第二检测组件102的检测结果Ry中。在对检测结果进行修正时,Rx-Ry=R1,如此,就能得到第一检测组件101的热敏电阻仅仅在与待测气体接触的影响下所发生的阻值变化,进而推算出待测气体的相关参数(例如气体浓度),提高检测精度。理想状态下,当待测气体的浓度为0时,Rx=Ry。但是,实际情况下,由于第一检测组件101与第二检测组件102的位置不同,二者所处的环境仍然存在差别,导致Ry≠R2。例如,气体流至第一壳体51的流速与气体流至第二壳体52的流速不等,流动至第一壳体51的气体与流动至第二壳体52的温度不同,等等。为了提高检测精度,需要尽量使第一检测组件101和第二检测组件102所处于的环境相同,从而使Ry无限趋近于R2。为了使第一检测组件101和第二检测组件102处于相同的环境,第一检测组件101与第二检测组件102具有相同的结构和尺寸,并且第一检测组件101与第一壳体51的相对位置也大致和第二检测组件102与第二壳体52的相对位 置保持一致。
在一些实施方式中,电路板6为平板状。在电路板6为平板状时,第一壳体51和第二壳体52并排设置在电路板6的同一侧。例如图30和图31,第一壳体51和第二壳体52均呈柱状,第一壳体51和第二壳体52从电路板6的相同侧凸出设置,第一壳体51的轴线和第二壳体52的轴线均与电路板6垂直,第一壳体51的轴线贯穿第一壳体51的第一开口5001。
本申请的第三方面提供一种传感装置的制造方法,包括以下步骤:
S1、提供检测组件100、壳体5和电路板6,检测组件100包括检测元件1、导电部20和底座4,例如图29,检测元件1与导电部20连接,导电部20与底座4连接;
S2、连接检测组件100与电路板6;
S3、将壳体5套设在至少部分检测组件100之外,连接壳体5与电路板6。
在本申请提供的传感装置的制造方法中,检测组件100和壳体5分别与电路板6连接,相对于先连接底座和壳体形成检测探头、再连接检测探头和电路板的制造方法而言,降低了底座4与壳体5之间的组装难度,进而降低了传感装置的制造难度。
在一些实施方式中,步骤S2中的连接为固定连接和电性连接。也就是说,步骤S2不仅实现检测组件100与电路板6的固定连接,还实现二者的电性连接。
在一些实施方式中,检测组件100的检测元件1与导电部20电性连接且固定连接,导电部20与底座4固定连接,导电部20与电路板6电性连接。具体地,电路板6上设置有用于安装导电部20的通孔601,例如图34所示。在一些实施方式中,步骤S2连接检测组件100和电路板6,包括:将导电部20贯穿通孔601,将导电材料填充至通孔601内,导电部20和电路板6通过导电材料电性连接和固定连接。
在一些实施方式中,在步骤S2完成后,底座4与电路板6之间有间隙。如此,减少检测组件100对电路板6散热的影响。
在一些实施方式中,设置在电路板6上的通孔601至少有一对,导电部20包括至少一对引出电极21、22和至少一对导电端子31、32,检测元 件1与至少一对引出电极21、22连接,至少一对引出电极21、22与至少一对导电端子31、32连接。至少一对导电端子31、32贯穿底座4并且与底座4固定连接。引出电极和导电端子各自的结构,以及引出电极与导电端子的连接关系如前文所述。
在一些实施方式中,在步骤S2连接检测组件100和电路板6的步骤之后,还包括:裁剪导电端子,去除导电端子的第二端部。第一导电端子31包括过渡段316,过渡段316位于电路板6的通孔601之内,过渡段316的一端与第一导电端子31的第一端部311连接,过渡段316的另一端与第一导电端子31的第二端部312连接,例如图29。在对第一导电端子31进行裁剪后,第一导电端子31仅包括位于第一腔501的第一端部311和位于通孔601内的过渡段316。同样地,第二导电端子32包括过渡段326,过渡段326位于电路板6的通孔601之内,过渡段326的一端与第二导电端子32的第一端部321连接,过渡段326的另一端与第二导电端子32的第二端部322连接。在对第二导电端子32进行裁剪后,第二导电端子32仅包括位于第二腔502的第一端部321和位于通孔601内的过渡段326,例如图29所示。在一些实施方式中,第一导电端子31的第一端部311、过渡段316和第二端部312同轴,第一导电端子31的半径为常数;第二导电端子32的第一端部321、过渡段326和第二端部322同轴,第二导电端子32的半径为常数。
在一些实施方式中,壳体5包括第一壳体51和第二壳体52,步骤S3、连接壳体5和电路板6,包括以下步骤:
S31、固定连接第一壳体51和电路板6,至少部分第一容腔511形成第一腔501,第一壳体51和电路板6均位于第一腔501的外围,第一开口5001气体性连通第一腔501和传感装置的外界;
S32、固定连接第二壳体52和电路板6,并且密封连接第二壳体52和电路板6,至少部分第二容腔521形成第二腔502,第二腔502为密封腔,第二壳体52和电路板6均位于第二腔502的外围。
在本申请中,由于第一壳体51与电路板6连接形成的第一腔501为开放腔,因此,第一壳体51与电路板6能够固定即可,其与电路板6的连接可以是密封连接,也可以不是密封连接。而第二壳体52需要与电路 板6连接形成封闭的第二腔502,因此,第二壳体52与电路板6的连接不仅要实现二者的固定,还要满足第二腔502的密闭性要求。因此,第二壳体52与电路板6密封连接。
尽管已经示出和描述了本申请的实施例,本领域的普通技术人员可以理解:在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型,本申请的范围由权利要求及其等同物限定。
