Description

光笼子组件、光模块连接器，及光笼子组件的制造方法
本申请要求于2020年12月29日提交的申请号为202011591349.9、发明名称为“光笼子组件、光模块连接器，及光笼子组件的制造方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光模块散热技术领域，特别涉及一种光笼子组件、光模块连接器，及光笼子组件的制造方法。
背景技术
光笼子是光通信设备的接口部件的壳体，具有插槽，插槽用于供光模块的电接头插入，以实现光模块和光笼子中的连接器相连。
考虑到光模块的电接头在插槽中的插拔，插槽和插入插槽中的光模块的电接头之间具有一定的间隙，以便于插拔。
为了给光模块散热，会在插槽的槽壁外表面安装散热器，以吸收光模块产生的热量。但是由于上述间隙的存在，将会降低光模块和散热器之间贴合程度，而降低两者之间的热传递速度，从而导致为光模块进行散热的效果较差。
发明内容
本申请提供了一种光笼子组件、光模块连接器，及光笼子组件的制造方法，能够克服相关技术中的问题，所述技术方案如下：
一方面，提供了一种光笼子组件，所述光笼子组件包括盒状壳体、散热器和罩状扣具；所述盒状壳体具有插槽，插槽是由盒状壳体的壳壁围成的槽状结构，所述插槽用于供光模块的电接头插入，所述盒状壳体的第一壳壁在靠近所述插槽槽口的位置处具有开口，所述第一壳壁为靠近所述插槽槽口的壳壁；所述散热器位于所述开口处，且能够与插入所述插槽中的电接头贴合；所述罩状扣具固定在所述盒状壳体的壳壁，且所述罩状扣具具有记忆合金件，所述记忆合金件位于所述散热器的远离所述开口的表面，所述记忆合金件被配置为：当温度高于温度阈值时，使所述散热器与位于所述插槽中的电接头紧密贴合，当温度低于所述温度阈值时，使所述散热器与位于所述插槽中的电接头之间存在间隙。
其中，温度阈值与光模块的工作温度相关，例如，温度阈值与光模块的工作温度比较接近，示例性地，温度阈值略小于光模块的工作温度。
这样，插槽中未插入光模块时，温度低于温度阈值，罩状扣具的记忆合金件的形状恢复至第二形状，记忆合金件处于收缩状态，记忆合金件向散热器施加的压力比较小，便于光模块的电接头的插入插槽中。
插槽中插入光模块的电接头以后，且光模块处于工作状态，光模块在工作中产生热量，促使温度升高，当温度高于温度阈值时，记忆合金件恢复至第一形状，记忆合金件处于伸展状态，记忆合金件向散热器施加的压力比较大，能够使散热器的底部与插槽中的电接头紧密贴合，加快电接头和散热器之间的热传递速度。
而当需要拔出光模块时，可以先控制光模块停止工作，光模块停止工作一段时间以后，温度能够降低至低于温度阈值，记忆合金件的形状恢复至第二形状，记忆合金件处于压缩状态，记忆合金件向散热器施加的压力比较小，便于光模块从插槽中拔出。
可见，具有上述结构的光笼子组件，在插槽中插拔光模块的电接头时，罩状扣具未压紧散热器，便于电接头的插拔，而光模块的电接头位于插槽中且处于工作状态时，罩状扣具压紧散热器，以增大电接头和散热器之间的贴合程度，加快电接头和散热器之间的热传递速度，增强为光模块进行散热的效果。
在一种可能的实施方式中，所述罩状扣具包括两个固定边框和至少一个箍紧边框，所述记忆合金件为所述箍紧边框；所述箍紧边框连接在所述两个固定边框之间，所述固定边框固定在所述盒状壳体的壳壁；当温度高于温度阈值时，所述箍紧边框向所述散热器的弯曲深度为第一数值，当温度低于所述温度阈值时，所述箍紧边框向所述散热器的弯曲深度为第二数值，所述第一数值大于零，所述第二数值小于所述第一数值。
在一种示例中，罩状扣具将散热器罩在罩状扣具的罩盖和插槽之间时，箍紧边框横向位于散热器的远离开口的表面。
温度高于温度阈值时，箍紧边框朝靠近散热器的方向伸展，例如，箍紧边框可以弯向散热器，且弯曲深度是第一数值，第一数值大于零。
温度低于温度阈值时，箍紧边框朝远离散热器的方向收缩，箍紧边框向散热器的弯曲深度为第二数值，第二数值小于第一数值。例如，第二数值可以大于零且小于第一数值，该状态下箍紧边框也弯向散热器。又例如，第二数值为零，该状态下箍紧边框平行于散热器。又例如，第二数值也可以小于零，该状态下，箍紧边框朝远离散热器的方向弯曲。
这样，当温度高于温度阈值时，箍紧边框的形状恢复至弯向散热器且弯曲深度为第一数值时的形状，此时，箍紧边框和散热器之间紧密贴合。而在温度由高于温度阈值向低于温度阈值变化中，箍紧边框朝远离散热器的方向抬离，当温度低于温度阈值时，箍紧边框的形状恢复至弯曲深度为第二数值时的形状，此时，箍紧边框和散热器之间具有间隙。
可见，温度高于温度阈值时，插槽中的电接头和散热器能够紧密贴合，加快两者之间的热量传递，为光模块加快散热。温度低于温度阈值时，插槽中的电接头和散热器之间具有间隙，用户能够很容易将光模块的电接头插入至插槽中，用户也很容易将位于插槽中的电接头拔出，进而便于用户在插槽中插拔光模块。
在一种可能的实施方式中，所述罩状扣具包括固定罩和至少一个螺旋件，所述记忆合金件为所述螺旋件；所述固定罩固定在所述盒状壳体的壳壁，所述螺旋件位于所述固定罩和所述散热器之间，且所述螺旋件垂直于所述散热器；当温度高于温度阈值时，所述螺旋件的长度为第三数值，当温度低于所述温度阈值时，所述螺旋件的长度为第四数值，所述第三数值大于所述第四数值。
在一种示例中，当温度高于温度阈值时，螺旋件的形状恢复至长度为第三数值时的形状，此时，螺旋件处于伸展状态，螺旋件和散热器之间紧密贴合，促使散热器与插槽中的电接头 紧密贴合。而当温度低于温度阈值时，螺旋件的形状恢复至长度为第四数值时的形状，此时，螺旋件处于收缩状态，能够促使散热器和插入插槽中的电接头之间存在间隙。
可见，温度高于温度阈值时，螺旋件的长度比较长，插槽中的电接头和散热器能够紧密贴合，加快两者之间的热量传递。温度低于温度阈值时，螺旋件的长度比较短，用户能够很容易将光模块的电接头插入至插槽中，用户也很容易将位于插槽中的电接头拔出，进而便于用户在插槽中插拔光模块。
而且，相比于记忆合金件为箍紧边框的方案，记忆合金件为螺旋形状的螺旋件，还能够显著提升记忆合金件的形变能力，例如，形变能力能够提升8至10倍。
在一种可能的实施方式中，所述螺旋件的一端固定在所述固定罩的内表面，所述螺旋件的另一端固定在所述散热器的远离所述开口的表面。
在一种示例中，位于散热器和固定罩的罩盖之间的螺旋件，螺旋件的一端与散热器远离插槽的表面固定，另一端与固定罩的罩盖内表面也固定，那么，当温度低于温度阈值时，螺旋件处于收缩状态，螺旋件能够将散热器抬起，使散热器和第一壳壁之间具有间隙，以便于用户轻松将位于插槽中的电接头拔出，或者，轻松将电接头插入至插槽中。
在一种可能的实施方式中，所述温度阈值和插入所述插槽中的光模块的工作温度相关。
其中，温度阈值与光模块的工作温度相关，例如，温度阈值与光模块的工作温度比较接近，示例性地，温度阈值略小于光模块的工作温度。
这样，当插槽中未插有光模块的电接头时，或者，当插槽中插有未处于工作状态的光模块的电接头时，插槽中的温度低于温度阈值。而当插槽中插有处于工作状态的光模块的电接头时，工作中的光模块产生大量的热量，促使插槽中的温度升高至高于温度阈值。
在一种可能的实施方式中，所述第一壳壁为与所述盒状壳体的固定壳壁相对的壳壁，所述固定壳壁用于实现所述盒状壳体的固定。
如上述所述，第一壳壁可以是邻近插槽的槽口位置的任一壳壁，靠近插槽的槽口的任一壳壁，也即是除了第二壳壁的任一壳壁，第二壳壁是与插槽的槽口的位置相对的壳壁。
例如，第一壳壁可以为与盒状壳体的固定壳壁相对的壳壁，固定壳壁是用于实现盒状壳体的固定的壳壁。该方案中，散热器的位置和固定壳壁的位置相对，方便该光笼子组件的安装，而且，罩状扣具的位置和固定壳壁的位置相对，也方便罩状扣具和盒状壳体的位置相对的两个侧壁相扣合。
在一种可能的实施方式中，所述散热器包括底座和凸台，所述凸台位于所述底座的表面；所述底座盖在所述开口的上方，所述凸台的位置和所述开口的位置相对，且所述凸台能够伸入至所述插槽中，与插入值所述插槽中的电接头紧密贴合。
这种结构的散热器，散热器的底座位于第一壳壁的外表面，而凸台能够穿过开口，伸入至插槽中，与插槽中的电接头接触，方便散热器在开口处的安装。
另一方面，提供了一种光模块连接器，所述光模块连接器包括连接器和权利要求至任一所述的光笼子组件；所述连接器位于所述插槽中，且所述连接器的电连接部的位置和所述插槽的槽口位置相对，所述电连接部用于和插入所述插槽中的光模块的电接头电连接；当插槽中插有处于工作状态的光模块时，罩状扣具的温度高于温度阈值，罩状扣具的记忆合金件能够促使散热器和插入至插槽中的电接头紧密贴合。当插槽中未插有光模块或者插有未处于工作状态的光模块时，罩状扣具的温度低于温度阈值，罩状扣具的记忆合金件能够促使散热器 和插入至插槽中的电接头之间存在间隙。
例如，当插槽中插有处于工作状态的光模块时，罩状扣具的温度高于温度阈值，罩状扣具的记忆合金件的形状恢复至第一形状，以增大罩状扣具对散热器的压力，促使散热器和插入插槽中的电接头紧密贴合。当插槽中未插有光模块或者插有未处于工作状态的光模块时，罩状扣具的温度低于温度阈值，罩状扣具的形状恢复至第二形状，以减少罩状扣具对散热器的压力，减少光模块的电接头在插槽中的插拔力。
可见，具有上述结构的光笼子组件，在插拔光模块的电接头时，罩状扣具未压紧散热器，便于电接头的插拔，而光模块的电接头位于插槽中且处于工作状态时，罩状扣具压紧散热器，以增大电接头和散热器之间的贴合程度，加快电接头和散热器之间的热传递速度，增强为光模块进行散热的效果。
另一方面，提供了一种光通信设备，该光通信设备可以包括上述所述的光模块连接器，如上所述，该光模块连接器的光笼子组件，在插拔光模块的电接头时，罩状扣具未压紧散热器，便于电接头的插拔，而光模块的电接头位于插槽中且处于工作状态时，罩状扣具压紧散热器，以增大电接头和散热器之间的贴合程度，加快电接头和散热器之间的热传递速度，增强为光模块进行散热的效果。进而，该光笼子组件，既能实现光模块在插槽中的轻松插拔，又能加快散热器和光模块之间的热传递速度，增强为光模块进行散热的效果。

而当需要拔出光模块时，可以先控制光模块停止工作，光模块停止工作一段时间以后，温度能够降低至低于温度阈值，记忆合金件的形状恢复至第二形状，向散热器施加的压力比较小，便于光模块从插槽中拔出。

具体实施方式
本申请实施例提供了一种光笼子组件，该光笼子组件为光通信设备的光模块连接器的壳体组件，光模块连接器是用于连接光模块的接口部件，以实现光通信设备之间的光通信。例如，第一光通信设备的光模块连接器插有第一光模块，第二光通信设备的光模块连接器插有第二光模块，第一光模块和第二光模块之间通过光缆连接，进而实现第一光通信设备和第二光通信设备之间的光通信。
光模块连接器还包括用于和光模块4进行电连接的连接器5。如图1所示，盒状壳体1具有插槽11，插槽11是由盒状壳体1的多个壳壁围成的槽状结构，如图2所示，连接器5位于插槽11中，且连接器5的电连接部51和插槽11槽口的位置相对，如图2所示，连接器5的电连接部51和插槽11的槽口之间还具有空间，该空间用于容纳光模块4的电接头41。这样，光模块4的电接头41可以穿过插槽11的槽口插入至插槽11中，与插槽11中的连接器5的电连接部51相连，从而实现光模块4与盒状壳体1中的连接器5电连接。
由于光模块4在工作中会产生大量热量，为了给光模块4散热，相应的，如图1所示，光笼子组件还包括散热器2，散热器2安装在盒状壳体1的外表面，而为了让散热器2能够和光模块4接触，相应的，如图2所示，盒状壳体1的第一壳壁12具有开口121，开口121用于安装散热器2。这样，散热器2安装在开口121处，且散热器2的底部能够穿过开口121，与位于插槽11中的电接头41贴合，以便于光模块4和散热器2能够接触，增大热传递速度。
其中，第一壳壁12可以是邻近插槽11的槽口位置的任一壳壁，靠近插槽11的槽口的任一壳壁，也即是除了第二壳壁13的任一壳壁，第二壳壁13是与插槽11的槽口的位置相对的壳壁。
例如，如图2所示，第一壳壁12可以为与盒状壳体1的固定壳壁14相对的壳壁，固定壳壁14是用于实现盒状壳体1的固定的壳壁。该方案中，散热器2的位置和固定壳壁14的位置相对，方便该光笼子组件的安装，而且，罩状扣具3的位置和固定壳壁14的位置相对， 也方便罩状扣具3和盒状壳体1的位置相对的两个侧壁相扣合。
又例如，第一壳壁12也可以为固定壳壁14，该方案中，固定壳壁14所固定的固定件，在对应固定壳体14的位置处也可以设置开口，以供散热器2依次穿过固定件的开口和固定壳壁14的开口，与插槽11中的电接头41接触。又例如，第一壳壁12也可以为与固定壳壁14相邻的两个侧壁。其中，本实施例对第一壳壁12具体为盒状壳体1的哪一个壳壁不做限定，可以根据实际情况，灵活选择。
关于开口121在第一壳壁12的具体设置，由于开口121的作用是供散热器2的底部穿过，与插入插槽11中的电接头41接触，相应的，开口121在第一壳壁12的位置为，对应插槽11的槽口和连接器5的电连接部51之间的空间的位置，该位置靠近插槽11的槽口。
在一种示例中，开口121的长度可以和插槽11的槽口与连接器5的电连接部51之间的距离相匹配，例如，两者相等。散热器2位于开口121处，散热器2与插入插槽11中的光模块4的电接头41接触，能够吸收光模块4的电接头41上的热量，为光模块4散热。
在另一种示例中，开口121的长度也可以大于插槽11的槽口与连接器5的电连接部51之间的距离。散热器2位于开口处，散热器2的一部分与插入插槽11中的电接头41接触，散热器2的另一部分与插槽11中的连接器5接触，散热器2能够吸收电接头41和连接器5的热量，为插入插槽11中的光模块4以及安装在插槽11中的连接器5散热。
其中，本实施例对开口121在第一壳壁12的具体设置，不做限定，能够实现位于开口121处的散热器2与插入插槽11中的电接头41贴合即可。
这样，散热器2位于开口121处，光模块4的电接头41插入插槽11中时，能够与插槽11上方的散热器2接触。
为了将散热器2稳固在开口121处，相应的，如图1所示，光笼子组件还包括罩状扣具3，如图3所示，罩状扣具3可以罩在散热器2远离开口121的表面，并固定在盒状壳体1的壳壁。这样，散热器2位于罩状扣具3的罩盖和插槽11之间。
如图3所示，罩状扣具3将散热器2固定在开口121处，如果罩状扣具3向散热器2施加的作用力比较大，会出现光模块4难以插入插槽11中，而如果罩状扣具3向散热器2施加的作用力比较小，会出现散热器2和插入插槽11中的电接头41之间的贴合效果较差，而导致散热器2和电接头41之间的热传递速率较慢。
为了解决上述矛盾，相应的，罩状扣具3具有记忆合金件，记忆合金件位于散热器2的远离开口121的表面，当温度高于温度阈值时，记忆合金件能够使散热器2与位于插槽11中的电接头41紧密贴合，当温度低于温度阈值时，记忆合金件能够让散热器2与位于插槽11中的电接头41之间存在间隙。
其中，记忆合金件是由具有双程记忆效应的记忆合金材质加工而成的部件，例如，记忆合金件可以由Au-Cd、Ag-Cd、Cu-Zn、Cu-Zn-Al、Cu-Zn-Sn、Cu-Zn-Si、Cu-Sn、Cu-Zn-Ga、In-Ti、Au-Cu-Zn、NiAl、Fe-Pt、Ti-Ni、Zr-Cu、Ni-Mn、Ti-Ni-Pd、Ti-Nb、U-Nb和Fe-Mn-Si合金中的至少一种材质加工而成。
记忆合金件具有记忆效果，对记忆合金件加工时，在高于温度阈值的温度下将记忆合金件加工成一种形状，可以记为第一形状，在低于温度阈值的温度为下将记忆合金件加工成另一种形状，可以记为第二形状。一旦温度高于温度阈值，记忆合金件便能够恢复成第一形状，一旦温度低于温度阈值，记忆合金件便能恢复至第二形状。
记忆合金件的形状为第一形状时，记忆合金件向散热器2施加的压力比较大，能够让散热器2和插入于插槽11中的电接头41紧密贴合。记忆合金件的形状为第二形状时，记忆合金件向散热器2施加的压力比较小，能够让散热器2和插入于插槽11中的电接头41之间存在一定的间隙。
其中，上述温度阈值与光模块4的工作温度相关，例如，温度阈值与光模块4的工作温度比较接近，示例性地，温度阈值略小于光模块4的工作温度。
这样，插槽11中未插入光模块4时，温度低于温度阈值，罩状扣具3的记忆合金件的形状恢复至第二形状，记忆合金件处于收缩状态，记忆合金件向散热器2施加的压力比较小，便于光模块4的电接头插入插槽11中。
插槽11中插入光模块4的电接头41以后，且光模块4处于工作状态，光模块4在工作中产生热量，促使温度升高，当温度高于温度阈值时，记忆合金件恢复至第一形状，记忆合金件处于伸展状态，记忆合金件向散热器2施加的压力比较大，能够使散热器2的底部与插槽11中的电接头41紧密贴合，加快电接头41和散热器2之间的热传递速度。
而当需要拔出光模块4时，可以先控制光模块4停止工作，光模块4停止工作一段时间以后，温度能够降低至低于温度阈值，记忆合金件的形状恢复至第二形状，记忆合金件处于压缩状态，记忆合金件向散热器2施加的压力比较小，便于光模块4从插槽11中拔出。
可见，具有上述结构的光笼子组件，在插拔光模块4的电接头41时，罩状扣具3未压紧散热器2，便于电接头41的插拔，而光模块4的电接头41位于插槽11中且处于工作状态时，罩状扣具3压紧散热器2，以增大电接头41和散热器2之间的贴合程度，加快电接头41和散热器2之间的热传递速度，增强为光模块4进行散热的效果。
其中，记忆合金件可以横向位于散热器2的表面，可以通过朝靠近散热器2的弯曲程度，来增大或减少向散热器2施加的压力。例如，记忆合金件朝靠近散热器2的弯曲程度比较大时，能够向散热器2施加比较大压力，促使散热器2和插入于插槽11中的电接头41紧密贴合。又例如，记忆合金件朝远离散热器2的弯曲程度比较小时，向散热器2施加的压力比较小，甚至不施加压力，促使散热器2和插入于插槽11中的电接头41之间存在间隙。
或者，记忆合金件也可以竖向位于散热器2的表面，可以通过拉伸增大向散热器2施加的压力，通过压缩来减少向散热器2施加的压力。例如，记忆合金件拉伸至长度比较长时，能够向散热器2施加比较大的压力，促使散热器2和插入于插槽11中的电接头41紧密贴合。又例如，记忆合金件压缩至长度比较短时，向散热器2施加的压力比较小，甚至不施加压力，促使散热器2和插入于插槽11中的电接头41之间存在间隙。
又或者，记忆合金件也可以是一部分横向位于散热器2的表面，另一部分竖向位于散热器2的表面，通过横向部分的弯曲程度，竖向部分的长度，来调整向散热器2施加的压力。
下面将结合罩状扣具3的具体形状，示例几种记忆合金件。
在一种示例中，记忆合金件可以是罩状扣具3的边框，例如，罩状扣具3可以是如图1所示的结构，包括两个固定边框31和至少一个箍紧边框32，固定边框31在形状上具有片状结构，箍紧边框32在形状上具有线状结构，每个箍紧边框32的两端分别连接在两个固定边框31之间，构成罩状结构的罩状扣具3。
上述所述的记忆合金件可以是箍紧边框32，罩状扣具3将散热器2罩在罩状扣具3的罩 盖和插槽11之间时，箍紧边框32横向位于散热器2的远离开口121的表面。
温度高于温度阈值时，箍紧边框32朝靠近散热器2的方向伸展，例如，箍紧边框32可以弯向散热器2，且弯曲深度是第一数值，第一数值大于零，可以参考如图4中(a)所示的结构示意图，以及如图5中(a)所示的结构示意图，图中h 1表示第一数值。
温度低于温度阈值时，箍紧边框32朝远离散热器2的方向收缩，箍紧边框32向散热器2的弯曲深度为第二数值，第二数值小于第一数值。例如，第二数值可以大于零且小于第一数值，该状态下箍紧边框也弯向散热器2，可以参考如图4中(b)所示的结构示意图。又例如，第二数值为零，该状态下箍紧边框32平行于散热器2，可以参考如图5中(c)所示的结构示意图。又例如，第二数值也可以小于零，该状态下，箍紧边框32朝远离散热器2的方向弯曲，图中h 2表示第二数值。
这样，如图6所示，当温度高于温度阈值时，箍紧边框32的形状恢复至弯向散热器2且弯曲深度为第一数值时的形状，此时，箍紧边框32和散热器2之间紧密贴合，可以参见图6中的(a)。而在温度由高于温度阈值向低于温度阈值变化中，箍紧边框32朝远离散热器2的方向抬离，当温度低于温度阈值时，箍紧边框32的形状恢复至弯曲深度为第二数值时的形状，此时，箍紧边框32和散热器2之间具有间隙，可以参见图6中的(b)。
可见，箍紧边框32在如图6中(a)所示的状态下，插槽11中的电接头41和散热器2能够紧密贴合，加快两者之间的热量传递。箍紧边框32在如图6中(b)所示的状态下，用户能够很容易将光模块4的电接头41插入至插槽11中，用户也很容易将位于插槽11中的电接头41拔出，进而便于用户在插槽11中插拔光模块4。
其中，箍紧边框32处于第一形状状态下的弯曲深度h 1的取值范围，与散热器2和位于插槽11中的电接头41之间的热传递速度相关，可以通过试验测试的方式，确定h 1的取值范围。同样，箍紧边框32处于第二形状状态下的弯曲深度h 2的取值范围，与电接头41在插槽11中的插拔情况相关，可以通过试验测试的方式，确定h 1的取值范围。
上述是记忆合金件为罩状扣具3的箍紧边框32的介绍。
在另一种示例中，记忆合金件也可以是螺旋件，相应的，如图7所示，罩状扣具3包括固定罩33和至少一个螺旋件34。固定罩33在形状上具有罩状，例如，可以是如图7所示，包括片状罩盖和两个片状罩壁的罩状结构，又例如，也可以是如图8所示，包括两个固定边框31和至少一个箍紧边框32的罩状结构。其中，本实施例对固定罩33的具体形状不做限定，能够实现罩在盒装壳体1的壳壁上，实现与盒装壳体1的壳壁固定即可。
上述所述的记忆合金件可以为螺旋件34，如图9所示，固定罩33罩在散热器2远离开口121的表面，且固定在盒装壳体1的壳壁上，螺旋件34竖向位于固定罩33的罩盖和散热器2之间，例如，螺旋件34的一端位于固定罩33的罩盖内表面处，另一端位于散热器2的远离插槽11的表面处。
温度高于温度阈值时，螺旋件34的形状为第一形状，螺旋件34处于伸展状态，例如，螺旋件34的长度为第三数值。温度低于温度阈值时，螺旋件34的形状为第二形状，螺旋件34处于收缩状态，例如，螺旋件34的长度为第四数值，第四数值小于第三数值。示例性地，如图10所示，图10中(a)为螺旋件34处于伸展状态下的形状，也即是，螺旋件34的形状为第一形状，d 1表示第三数值，图10中(b)为螺旋件34处于收缩状态下的形状，也即是， 螺旋件34的形状为第二形状，d 2表示第四数值。
这样，如图11所示，当温度高于温度阈值时，螺旋件34的形状恢复至长度为第三数值时的形状，此时，螺旋件34处于伸展状态，螺旋件34和散热器2之间紧密贴合，促使散热器2与插槽11中的电接头41紧密贴合，可以参见图11中的(a)。而当温度低于温度阈值时，螺旋件34的形状恢复至长度为第四数值时的形状，此时，螺旋件34处于收缩状态，螺旋件34和固定罩33的罩盖之间具有间隙，或者，螺旋件34和散热器2之间具有间隙，或者，散热器2和第一壳壁12之间具有间隙，具体为哪一种见如下分析：
其中，位于散热器2和固定罩33的罩盖之间的螺旋件34，可以竖向放置在散热器2和固定罩33的罩盖之间，螺旋件34的一端与散热器2远离插槽11的表面不固定，另一端与固定罩33的罩盖也不固定，如图11中的(b)所示，螺旋件34处于收缩状态时，螺旋件34和固定罩33的罩盖之间具有间隙。
或者，位于散热器2和固定罩33的罩盖之间的螺旋件34，也可以一端与散热器2的远离插槽11的表面固定，螺旋件34的另一端与固定罩33的罩盖内表面不固定，也是参考如图11中的(b)所示，螺旋件34处于收缩状态时，螺旋件34和固定罩33的罩盖之间具有间隙。
或者，位于散热器2和固定罩33的罩盖之间的螺旋件34，螺旋件34的一端与散热器2远离插槽11的表面不固定，另一端与固定罩33的罩盖内表面固定，如图11中的(c)所示，螺旋件34处于收缩状态时，螺旋件34能够将散热器2抬起，使散热器2和第一壳壁12之间具有间隙。
或者，位于散热器2和固定罩33的罩盖之间的螺旋件34，螺旋件34的一端与散热器2远离插槽11的表面固定，另一端与固定罩33的罩盖内表面也固定，如图11中的(c)所示，螺旋件34处于收缩状态时，螺旋件34能够将散热器2抬起，使散热器2和第一壳壁12之间具有间隙。
可见，螺旋件34在如图11中(a)所示的状态下，插槽11中的电接头41和散热器2能够紧密贴合，加快两者之间的热量传递。螺旋件34在如图11中(b)和(c)所示的状态下，用户能够很容易将光模块4的电接头41插入至插槽11中，用户也很容易将位于插槽11中的电接头41拔出，进而便于用户在插槽11中插拔光模块4。
而且，相比于记忆合金件为箍紧边框32的方案，记忆合金件为螺旋形状的螺旋件34，还能够显著提升记忆合金件的形变能力，例如，形变能力能够提升8至10倍。
其中，螺旋件34处于第一形状状态下的长度d 1的取值范围，与散热器2和位于插槽11中的电接头41之间的热传递速度相关，应用时可以通过试验测试的方式，确定d 1的取值范围。同样，螺旋件34处于第二形状状态下的长度d 2的取值范围，与电接头41在插槽11中的插拔情况相关，应用时可以通过试验测试的方式，确定d 1的取值范围。
在另一种示例中，罩状扣具3的固定罩33为如图8所示的结构时，记忆合金件也可以是箍紧边框32和螺旋件34，其中，螺旋件34的一端固定在箍紧边框32的内表面，螺旋件34的另一端可以位于散热器2远离插槽11的表面，也可以固定在散热器2远离插槽11的表面。
那么，记忆合金件为第一形状时，箍紧边框32和螺旋件34均处于伸展状态，例如，箍紧边框32的弯曲深度为第五数值，螺旋件34的长度为第六数值，记忆合金件为第二形状时，箍紧边框32和螺旋件34均处于收缩状态，例如，箍紧边框32的弯曲深度为第七数值，螺旋 件34的长度为第八数值，第七数值小于第五数值，第八数值小于第六数值。其中，第五数值可以与第一数值相等，也可以不相等，第六数值可以与第三数值相等，也可以不相等，第七数值可以与第二数值相等，也可以不相等，第八数值可以与第四数值相等，也可以不相等。本实施例对此不做限定，应用时可以根据实际情况，灵活选择。
其中，本实施例对记忆合金件为箍紧边框32，还是为螺旋件34，还是为箍紧边框32和螺旋件34，不做限定，应用时可以根据实际情况，灵活选择。
如上述所述，散热器2位于开口121处，例如，一种情况可以是，散热器2的底部能够穿过开口121，散热器2的顶部凸出于开口121，示例性地，如图11所示，散热器2可以包括底座21和凸台22，凸台22位于底座21的表面，例如，凸台22位于底座21的上表面或者下表面，底座21盖在开口121的上方，凸台22的位置和开口121的位置相对，且凸台22能够伸入至插槽11中，与插槽11中的电接头41紧密贴合。
其中，底座21的远离凸台22的位置处可以具有散热翅，以增加散热器2的散热面积，加快为光模块4的散热，提升散热效果。
又例如，散热器2位于开口121处的另一种情况可以是，散热器2的面积小于开口121的面积，散热器2位于开口121中，且由位于盒装壳体1中的连接器5支撑。
又例如，散热器2位于开口121处的另一种情况可以是，散热器2的面积小于开口121的面积，散热器2能位于开口121中，但是盒装壳体1的壳壁内表面具有凸起结构，散热器2由盒装壳体1的壳壁内表面具有凸起结构支撑。
又例如，散热器2位于开口121处的另一种情况可以是，散热器2为楔形结构，散热器2的底部能够位于开口121中，而散热器2的顶部凸出于开口121。
其中，本实施例对散热器2在开口121处的具体安装关系不做限定，应用时可以根据实际情况，灵活选择。
如上述所述，罩状扣具3固定在盒装壳体1的壳壁，相应的，罩状扣具3的罩壁和盒装壳体1的壳壁可以通过卡扣实现扣合，罩状扣具3和盒装壳体1之间为可拆卸安装，以便于对光笼子组件进行拆装。
在本申请实施例中，插槽11中未插入光模块4时，温度低于温度阈值，罩状扣具3的记忆合金件的形状恢复至第二形状，记忆合金件处于收缩状态，记忆合金件向散热器2施加的压力比较小，便于光模块4的电接头插入插槽中。插槽11中插入光模块4的电接头41以后，且光模块4处于工作状态，光模块4在工作中产生热量，促使温度升高，当温度高于温度阈值时，记忆合金件恢复至第一形状，记忆合金件处于伸展状态，记忆合金件向散热器2施加的压力比较大，能够使散热器2的底部与插槽11中的电接头41紧密贴合，加快电接头41和散热器2之间的热传递速度。而当需要拔出光模块4时，可以先控制光模块4停止工作，光模块4停止工作一段时间以后，温度能够降低至低于温度阈值，记忆合金件的形状恢复至第二形状，记忆合金件处于压缩状态，记忆合金件向散热器2施加的压力比较小，便于光模块4从插槽11中拔出。
可见，具有上述结构的光笼子组件，在插拔光模块4的电接头41时，罩状扣具3未压紧散热器2，便于电接头41的插拔，而光模块4的电接头41位于插槽11中且处于工作状态时， 罩状扣具3压紧散热器2，以增大电接头41和散热器2之间的贴合程度，加快电接头41和散热器2之间的热传递速度，增强为光模块4进行散热的效果。进而，该光笼子组件，既能实现光模块在插槽中的轻松插拔，又能加快散热器和光模块之间的热传递速度，增强为光模块进行散热的效果。
本实施例还提供了一种光模块连接器，如图12所示，该光模块连接器包括连接器5和上述所述的光笼子组件；连接器5位于盒状壳体1的插槽11中，且连接器5的电连接部51的位置和插槽11的槽口位置相对，电连接部51和插槽11的槽口之间具有用于容纳光模块4的电接头41的空间，这样，光模块4的电接头41可以穿过插槽11的槽口插入至插槽11中。
当插槽11中插有处于工作状态的光模块4时，罩状扣具3的温度高于温度阈值，罩状扣具3的记忆合金件能够促使散热器2和插入至插槽11中的电接头41紧密贴合。当插槽11中未插有光模块4或者插有未处于工作状态的光模块4时，罩状扣具3的温度低于温度阈值，罩状扣具3的记忆合金件能够促使散热器2和插入至插槽11中的电接头41之间存在间隙。
例如，当插槽11中插有处于工作状态的光模块4时，罩状扣具3的温度高于温度阈值，罩状扣具3的记忆合金件的形状恢复至第一形状，以增大罩状扣具3对散热器2的压力，促使散热器2和插入插槽11中的电接头41紧密贴合。当插槽11中未插有光模块4或者插有未处于工作状态的光模块4时，罩状扣具3的温度低于温度阈值，罩状扣具3的形状恢复至第二形状，以减少罩状扣具3对散热器2的压力，减少光模块4的电接头41在插槽11中的插拔力。
可见，具有上述结构的光笼子组件，在插拔光模块4的电接头41时，罩状扣具3未压紧散热器2，便于电接头41的插拔，而光模块4的电接头41位于插槽11中且处于工作状态时，罩状扣具3压紧散热器2，以增大电接头41和散热器2之间的贴合程度，加快电接头41和散热器2之间的热传递速度，增强为光模块4进行散热的效果。进而，该光笼子组件，既能实现光模块在插槽中的轻松插拔，又能加快散热器和光模块之间的热传递速度，增强为光模块进行散热的效果。
本实施例还提供了一种光通信设备，该光通信设备可以包括上述所述的光模块连接器，如上所述，该光模块连接器的光笼子组件，在插拔光模块4的电接头41时，罩状扣具3未压紧散热器2，便于电接头41的插拔，而光模块4的电接头41位于插槽11中且处于工作状态时，罩状扣具3压紧散热器2，以增大电接头41和散热器2之间的贴合程度，加快电接头41和散热器2之间的热传递速度，增强为光模块4进行散热的效果。进而，该光笼子组件，既能实现光模块在插槽中的轻松插拔，又能加快散热器和光模块之间的热传递速度，增强为光模块进行散热的效果。
本实施例还提供了一种光笼子组件的制造方法，该方法用于制造上述所述的光笼子组件，该方法可以包括如下过程：
首先，将散热器2放置于盒状壳体1的开口121处。
其中，开口121位于盒状壳体1的第一壳壁12靠近插槽11槽口的位置处，第一壳壁12为靠近插槽11槽口的壳壁。
其次，将罩状扣具3固定在盒状壳体1的壳壁。
例如，罩状扣具3包括两个固定边框31和至少一个箍紧边框32，箍紧边框32连接在两个固定边框31之间，两个固定边框31分别与盒装壳体1的位置相对的两个壳壁固定，箍紧边框32位于散热器2的远离插槽11的表面。
又例如，罩状扣具3包括固定罩33和螺旋件34，固定罩33的位置相对的两个罩壁分别与盒装壳体1的位置相对的两个壳壁固定，螺旋件34位于固定罩33的罩盖和散热器2之间，且螺旋件34的一端位于固定罩33的罩盖内表面处，另一端位于散热器2的远离插槽11的表面处。
其中，罩状扣具3具有记忆合金件，记忆合金件位于散热器2的远离开口121的表面，当温度高于温度阈值时，记忆合金件促使散热器2和插入插槽11中的电接头41紧密贴合，当温度低于温度阈值时，记忆合金件促使散热器2和插入插槽11中的电接头41之间存在间隙。
例如，记忆合金件可以为箍紧边框32，温度高于温度阈值时，箍紧边框32弯向散热器2，且弯曲深度为第一数值。温度低于温度阈值时，箍紧边框32弯向散热器2，且弯曲深度为第二数值，第二数值小于第一数值。或者，温度低于温度阈值时，箍紧边框32平行于散热器2。或者，温度低于温度阈值时，箍紧边框32朝远离散热器2的方向弯曲。
又例如，记忆合金件为螺旋件34，温度高于温度阈值时，螺旋件34处于伸长状态，其长度为第三数值。温度低于温度阈值时，螺旋件34处于压缩状态，其长度为第四数值，第四数值小于第三数值。
又例如，记忆合金件为箍紧边框32和螺旋件34，温度高于温度阈值时，箍紧边框32弯向散热器2，螺旋件34处于伸长状态。温度低于温度阈值时，箍紧边框32未弯向散热器2，螺旋件34处于压缩状态。或者，温度低于温度阈值时，箍紧边框32稍微弯向散热器2，螺旋件34处于压缩状态。或者，温度低于温度阈值时，箍紧边框32向远离散热器2的方向弯曲，螺旋件34处于压缩状态。
由上述可见，具有上述结构的光笼子组件，在插拔光模块4的电接头41时，罩状扣具3未压紧散热器2，便于电接头41在插槽11中的插拔，而光模块4的电接头41位于插槽11中且处于工作状态时，罩状扣具3压紧散热器2，以增大电接头41和散热器2之间的贴合程度，加快电接头41和散热器2之间的热传递速度，增强为光模块4进行散热的效果。进而，该光笼子组件，既能实现光模块在插槽中的轻松插拔，又能加快散热器和光模块之间的热传递速度，增强为光模块进行散热的效果。
以上所述仅为本申请一个实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
