连接器的接触件模块及连接器Connector contact module and connector

技术领域technical field

本发明涉及连接器的接触件模块及连接器。The present invention relates to a contact module of a connector and a connector.

背景技术Background technique

为了保证传输质量，连接器往往需要设置防尘结构，特别是光纤连接器。光纤连接器传输光信号的基本原理是：两个光纤插芯端面的精密对接实现光信号的耦合。光纤插芯核心区域纤芯直径一般仅有9um～62.5um，灰尘(常见PM2.5或者PM10)如果在接触区域就会对光信号通路造成遮挡，使IL(插入损耗)增大。光纤连接的位置对灰尘非常敏感，所以对接端面的防尘非常重要。In order to ensure transmission quality, connectors often need to be provided with dust-proof structures, especially optical fiber connectors. The basic principle of optical signal transmission by optical fiber connector is: the precise butt joint of the end faces of two optical fiber ferrules realizes the coupling of optical signals. The diameter of the fiber core in the core area of the optical fiber ferrule is generally only 9um to 62.5um. If dust (commonly PM2.5 or PM10) is in the contact area, it will block the optical signal path and increase the IL (insertion loss). The position of the optical fiber connection is very sensitive to dust, so the dustproof of the mating end face is very important.

光纤连接器用于设备柜体内时，由于设备柜体上设有用于散热的风扇，而风扇运转时会带动携带有灰尘的气流在设备内部循环流动，使得光纤连接器附近持续有流动的空气(携带灰尘)，连接器外壳之间如果有缝隙，或者在连接器插拔的瞬间，流动的空气携带的灰尘很容易进入连接器内部，很可能污染到插芯端面，造成插入损耗变大。When the optical fiber connector is used in the equipment cabinet, since the equipment cabinet is equipped with a fan for heat dissipation, and when the fan is running, it will drive the airflow carrying dust to circulate inside the equipment, so that there is continuous flowing air near the optical fiber connector (carrying Dust), if there is a gap between the connector shells, or at the moment when the connector is plugged and unplugged, the dust carried by the flowing air can easily enter the interior of the connector, which is likely to contaminate the end face of the ferrule, resulting in increased insertion loss.

为了实现连接器的防尘，现有技术中提出了在连接器的插接口设置防尘门的技术方案，例如授权公告号为CN106299841B的中国专利公开的连接器采用的防尘门。现有技术中还有在接触件模块的插接端设置防尘门的技术方案，如公布号为CN105024219A的中国专利申请中公开的连接器所采用的防尘板。现有的上述连接器中的防尘门的能够对连接器壳内设置的接触件模块进行遮挡，起到防尘作用。但是，现有的连接器的接触件模块往往是插设在连接器壳上设置的模块容纳腔内，并且大部分接触件模块需要能够实现插拔以便于装配和维护，为了实现接触件模块的插拔，接触件模块的模块壳体与模块容纳腔的腔壁之间需要有一定配合间隙，连接器使用过程中，灰尘容易从该配合间隙内进入连接器壳，进而会对接触件模块中的接触件造成污染，影响连接器的性能。In order to realize the dustproof of the connector, the prior art proposes a technical solution of arranging a dustproof door at the plug-in interface of the connector, such as the dustproof door used in the connector disclosed in the Chinese Patent with the Authorization Bulletin No. CN106299841B. In the prior art, there is also a technical solution of arranging a dustproof door at the plug-in end of the contact module, such as the dustproof plate used in the connector disclosed in the Chinese Patent Application Publication No. CN105024219A. The dust-proof door in the existing connector can shield the contact module provided in the connector housing, and play a role of dust-proof. However, the contact module of the existing connector is often inserted into the module accommodating cavity provided on the connector shell, and most of the contact modules need to be able to be plugged and unplugged to facilitate assembly and maintenance. When plugging and unplugging, there needs to be a certain matching gap between the module shell of the contact module and the cavity wall of the module accommodating cavity. During the use of the connector, dust can easily enter the connector shell from the matching gap, which will cause damage to the contact module. The contacts cause contamination and affect the performance of the connector.
