技术领域
本发明涉及连接器组件和包括该连接器组件的摄像组件。 背景技术
车载摄像机（头）能提供车厢内外环境的监控，为车辆行驶提供安全保障。 现有的 车载普通摄像机其输入 /输出多采用猪尾式（ pigtail )电缆。 随着对车载摄像机图像质量 要求的提高，高清摄像技术逐渐被引入到车载摄像机上来。 采用同轴连接件作为信号的 输入和输出器件能够提高信号传输的稳定性。
图 1 和图 2示出了一种金属外壳同轴连接件 100，其外壳 101 由金属制成。 外壳 101 的一端具有圆筒形套筒 102，套筒 102上设置有卡扣 103，用来与对配连接器进行 连接。 外壳 101 内设置有中心针 104、 绝缘层 105和屏蔽层 107，其中 ，屏蔽层 107 与外壳 101 为一体形成件。 图 2 中 ， 中心针 104的左端用来与对配连接器连接，右端 用来与控制电路板连接。

具体实施方式
下面结合附图详细描述本发明的连接器组件和带有该连接器组件的摄像组件。 摄像 组件包括各种摄像头，如高清摄像机。 本领域技术人员应当理解，下面描述的实施例仅 是对本发明的示例性说明 ，而非用于对其作出任何限制。 在所有附图中 ，相同的附图标 记表示相同或相似的部件。
根据本发明的连接器组件主要包括基座和同轴连接件。 基座可以是一体件也可以是 分体件组装而成。 为了保证信号质量，基座通常还作为机器的接地端。 因此，基座通常 由金属或含有金属部件形成。
图 5和图 6示出了一种带有分体式基座的连接器组件 300。 基座包括盖板 310和壳 体 320。 盖板 310上设置有套筒 31 1 ，套筒 31 1外壁设置有卡扣 312，用来与对配连接 器进行卡接。 壳体 320上设置有连接孔 321。 同轴连接件 330穿过连接孔 321 并插入 到套筒 31 1 中。 如下文中所述，上述连接器组件 300结构形成标准的 Fakra插接端， 能够与现有的带有 Fakra插接头的对配连接器进行插接。 在根据本发明的连接器组件实 施例中 ，同轴连接件 330和基座 310,320之间呈间隙配合，以避免同轴连接件 330在 连接器组件 300使用中受力。 特别地，同轴连接件 330分别与盖板 310和壳体 320间 隙配合。
盖板 310和壳体 320上分别设置有安装结构，用于安装连接器组件 300。 例如， 安装结构可设置成安装孔 315和 325，可通过螺栓进行固定连接。 为了方便安装，盖板 310 与壳体 320 之间可以设置有定位结构。 图 5-6 中示出了一种定位结构，包括盖板 310外缘上设置的凸起 314和壳体 320上对应设置的凹槽 324。 安装时，盖板 310和 壳体 320通过凸起 314与凹槽 324的卡合能够迅速地准确定位。 在其它实施例中 ，也 可以采用已知的其它定位结构。 为了结构简单的目的 ，也可以不设置上述定位结构，盖 板 310和壳体 320直接以平板接触的方式固定连接。
为了防止与对配连接器插错，在套筒 31 1的外壁上还可以设置有一个或多个定位结 构，如定位销 313。 设置有不同位置和 /或不同个数定位销 313的多个盖板 310可以适 配多个不同功能的对配连接器。 采用上述分体式基座的情况下，当连接器组件 300需要 连接新的对配连接器时，仅需更换盖板 310 即可，操作简单。 优选情况下，盖板 310 采用塑料制成，壳体 320采用金属制成，从而既能保证基座作为接地端的功能，又能节 省材料成本，减轻重量。
图 7 示出了使用上述连接器组件 300 的像机组件的剖视示意图。 像机组件由前盖 500和基座（盖板 310和壳体 320 )形成封闭机壳体。 机壳体内固定设置有控制电路板 400，如，该控制电路板 400可固定安装在前盖 500上。 前盖 500上安装有光学组件 (未示出 )。 高清像机的其它结构和元件都是本领域技术人员所熟知的 ，在此省略对它 们的描述。
参见图 7，同轴连接件 330包括中心导体 331、 环绕中心导体设置的外导体 333、 以及设置在中心导体 331 和外导体 333之间的绝缘体 332。 如图 8中所示，同轴连接 件 330的上端为对配端，用于与对配连接器 600插接；同轴连接件 330的下端为控制 端，用于连接控制电路板 400。 中心导体 331 的一端，如上端 331 a用来与对配连接器 的信号导体连接， 中心导体 331 的另一端，如下端 331 b与控制电路板 400 的连接孔 401 插接，用来输入 /输出信号。 为了增强同轴连接件 330 与控制电路板 400 的固定 性，在外导体 333 的下端还设置有焊接脚 334，用来与控制电路板 400焊接固定。 另 外，为了使外导体 333有效接地，外导体 333需要与壳体 320保持连接。 可以通过在 外导体 333的下端设置金属接地圈 335来与壳体 320连接。
为了防止外界水分进入摄像组件内部，连接器组件 300设计有防水结构。 在本发明 的一个实施例中 ， 防水结构可包括第一密封体 340，该第一密封体 340 分别与基座 310,320和同轴连接件 330密封连接。 在如图所示的一示例中 ，第一密封体 340设置在 盖板 310和壳体 320之间 ，并分别与盖板 310和壳体 320密封连接。 在如图所示的另 一示例中 ，第一密封体 340 为一密封圈，套设在外导体 333 的外表面，并与其密封连 接。 当盖板 310安装至壳体 320上时，通过盖板 310挤压第一密封体 340，从而使第 一密封体 340分别与盖板 310和壳体 320密封连接，实现同轴连接件 330的上下两侧 密封。
在同轴连接件 330朝向对配连接器的对配端， 中心导体 331 与外导体 333之间还 设置有第二密封体 350，第二密封体 350分别与中心导体 331 的外表面和外导体 333 的内表面实现周向密封。 通过第二密封体 350使得同轴连接件 330 内部与外界密封。 第一密封体 340和第二密封体 350通常采用弹性橡胶密封圈。
参见图 8，根据本发明的连接器组件 300还可以包括对配连接器 600，对配连接器 600的壳体通过套筒 31 1 上的卡扣 312卡接后与盖板 310固定连接。 对配连接器 600 内部的信号导体 601 与中心导体 331 对配连接。 对配连接器 600可以连接中控台，从 而实现摄像组件的信号输入 /输出。
摄像组件在使用状态下，当对配连接器 600受到拉力时（图 8中箭头 A所示） ， 拉力传递到盖板 310以及与盖板 310 固定连接的下盖板 320，乃至安装整个摄像组件 的设备壳体上，而不会传递到同轴连接件 330 或控制电路板 400 上。 因此，本发明的 连接器组件 300能够有效防止同轴连接件 330与控制电路板 400接触故障的发生，保 证信号传输的稳定性。 请参阅图 9 至图 1 1 ，其为本发明提供的一种同轴连接器组件 101。 所述同轴连接 器组件 101 可用于支撑、 设置同轴电缆。 所述同轴连接器组件 101包括本体 10及屏蔽 件 20。 所述屏蔽件 20安装在所述主体 10上，且所述屏蔽件 20可用于屏蔽电磁干扰。 请继续参阅图 9至图 11 ，所述本体 10包括筒体 11及屏蔽配合部 15。 为了容置同 轴电缆，所述本体 10沿轴向贯穿开设有连接通孔 14。 所述连接通孔 14贯穿所述筒体 11及所述屏蔽配合部 15。 所述筒体 11沿轴向延伸设置。 所述筒体 11用于容置下述能 够与同轴电缆相连接的中心导体。 所述筒体 11 的延伸长度、 径向尺寸及具体外形根据 需要而设置。 在本实施例中 ，所述筒体 11 大致为圆筒形。 所述筒体 11 的外周壁上设 置有阻挡部 111。 所述阻挡部 111 的具体形状及结构只要能够实现对所述屏蔽件 20的 阻挡即可，譬如所述阻挡部 111可以为卡扣、 凸台或凸柱等结构。 在本实施例中 ，所述 阻挡部 111包括沿倾斜引导面（图中未示）及阻挡平面（图中为示）。 所述倾斜引导面 与所述筒体 11 的外周壁相交且倾斜设置，以便于所述屏蔽件 20 安装。 所述阻挡平面 与所述倾斜引导面连接，且所述阻挡平面垂直设置在所述筒体 11 的外周壁上，从而达 到最佳的阻挡效果。 所述阻挡部 111 的数量根据需要而选择，可以为一个、 两个或多 个。 为了均勻阻挡受力 ，在阻挡部 111 为多个时，该多个阻挡部 111 中的任意两个阻 挡部 111的间距相等。 在本实施例中 ，所述阻挡部 111为四个。
所述屏蔽配合部 15 设置在所述筒体 11 的端部。 在本实施例中 ，所述屏蔽配合部 15设置在所述筒体 11的前端。 所述屏蔽配合部 15具有大于所述筒体 11的径向尺寸， 从而便于实现对所述屏蔽件 20 的阻挡。 当然，所述屏蔽配合部 15 也可以具有大于所 述筒体 11 的横截面面积。 在本实施例中 ，所述屏蔽配合部 15 大致设置为与所述筒体 11 同轴的圆锥形。 为了实现便于实现对所述屏蔽件 20的活动区域的限制，所述屏蔽配 合部 15 的外周壁上开设有限制槽 16。 所述限制槽 16 具有一对相对设置的阻挡侧壁 (图中未示）。 具体地，所述一对阻挡侧壁之间的间距沿着将所述屏蔽件 20 安装在所 述本体 10 上的方向逐渐增大。 所述阻挡侧壁也可以相对于所述屏蔽配合部 15 的外周 壁倾斜设置，以便于下述屏蔽件 20的安装爪 25述限制槽 16移动至所述屏蔽配合部 15 的外周壁上以实现拆卸。 所述限制槽 16 的深度（也即阻挡侧壁的高度）、 具体形状只 要符合限制所述屏蔽件 20 的需要即可。 在本实施例中 ，所述限制槽 16 等深度设置。 所述限制槽 16的两端均设置为开口（图中未示） ，以便于下述屏蔽件 20的安装爪 25 该限制槽 16 的开口方向移动。 可以想到的是，所述限制槽 16 的两端与两侧分别首尾 相连。 为了便于将所述屏蔽件 20 稳固设置在所述本体 10 上以获得稳定的电磁屏蔽性 能，所述本体 10还包括抵紧台面 18。 所述抵紧台面 18设置在所述限制槽 16的底面， 并相对设置在所述筒体 11呈锥面设置。 所述抵紧台面 18与所述屏蔽件 20的安装爪 25 相抵接。
为了实现与下述电路板的机械连接，或者通过机械连接实现电连接，所述本体 10 还包括连接部 19。 所述连接部 19沿所述本体 10的轴向延伸设置在所述屏蔽配合部 15 的自由端上。 所述连接部 19 的数量、 尺寸及具体形状根据连接需要而选择。 在本实施 例中 ，所述连接部 19为三个，且三个连接部 19分别位于所述屏蔽配合部 15的前端的 圆形横截面的两条垂直的直径的任意三个端点上。 在本实施例中 ，所述连接部 19 为沿 所述本体 10 的轴向突出设置的连接柱。 当然，所述连接部 19 还可以为法兰、 卡扣或 挂钩等结构。
为了实现增强机械强度，所述本体 10 为一体件。 具体地，所述本体 10 采用金属 制成一体件。
请一并参阅图 12及图 13，所述屏蔽件 20包括套设部 21及安装爪 25。 所述套设 部 21 上开设有安装通孔 211。 所述安装通孔 211 的具体形状、 大小只要满足套设在所 述本体 10上且在沿所述本体 10的轴向的前后两端上分别受到所述阻挡部 111 与所述 屏蔽安装部 15的阻挡即可。 在本实施例中 ，为了便于转动以实现拆装，所述套设部 21 设置为圆板状。 所述安装通孔 211设置为与圆形通孔。
为了便于实现安装，在本实施例中 ，所述套设部 21 还开设有用于通过所述阻挡部 111 的安装缺口 212。 所述安装缺口 212与所述安装通孔 211 相连通。 所述安装缺口 212 的形状及尺寸只要能够使得所述套设部 21 从所述筒体 11 的尾端越过所述阻挡部 111 实现安装即可。 具体地，所述安装缺口 212在沿所述本体 10的径向上具有大于或 等于所述阻挡部 111 的最大高度，且所述安装缺口 212在沿所述本体 10的周向（即所 述筒体 11 的周向）具有大于或等于所述阻挡部 111 的延伸长度，从而使得所述套设部 21通过所述安装缺口 211越过阻挡部 111 而实现安装。 当然，在所述阻挡部 111为两 个或多个时，所述安装缺口 212的数量及位置与所述阻挡部 111相匹配。
可以想到的是，所述屏蔽件 20 可以通过两个部分或多个部分围绕所述本体 10 设 置且位于所述阻挡部 111 与所述屏蔽配合部 15之间 ，然后该两个部分或多个部分通过 螺接、 卡接或焊接等方式拼接一体而成为所述屏蔽件 20。 因此，所述安装缺口 212 不 是必要的。
为了便于安装而采用安装缺口 212的前提下，又能够实现对所述屏蔽件 20的阻挡 以限制该屏蔽件 20的活动区域，所述阻挡部 1 11与所述限制槽 16在沿所述本体 10的 轴向上间隔且交错设置。 因而，所述屏蔽件 20的安装爪 25在沿所述本体 10的周向时 与所述限制槽 16 阻挡配合（即在一定的转动力驱动下，所述屏蔽件 20 只能在所述限 制槽 16内区域以所述本体 10的中心轴自转） ，且所述屏蔽件 20在沿所述本体 10的 轴向上被限制在所述阻挡部 1 1 1与所述屏蔽配合部 15之间。
所述安装爪 25沿靠近所述屏蔽配合部 15的方向突出设置在所述套设部 21。 所述 安装爪 25的形状及尺寸只要满足在沿所述屏蔽配合部 15的周向上与所述限制槽 16阻 挡配合，且可沿着所述限制槽 16 的开口移动至抵接在所述抵紧台面 18 即可。 在本实 施例中 ，所述安装爪 25 设置为沿靠近所述屏蔽配合部 15 的方向延伸的板状（即片 状） ；且所述安装爪 25 为了便于实现沿着所述限制槽 16 的开口方向移动 ，所述安装 爪 25 设置为等腰梯形，且就该等腰梯形较短的底边位于所述限制槽 16 内。 所述安装 爪 25可以平行于所述本体 10的中心轴线延伸设置；所述安装爪 25也可沿与所述本体 10的中心轴线相交的方向延伸设置，此时，所述安装爪 25可以呈放射状或收縮状。 在 本实施中 ，为了便于实现从所述限制槽 16 内移动至所述抵紧台面 18 上，所述安装爪 25设置为放射状。 进一步地，所述安装爪 25的自由端还设置有上翘部（图中为标示） 以减少移动时与所述限制槽 16之间的摩擦力。
为了提升所述安装爪 25与所述抵接台面 18的稳定接触性能，所述安装爪 25沿平 行于所述屏蔽件 20的轴向方向设置。 所述安装爪 25的自由端弯折形成接触部 251。 所 述接触部 251与所述抵接台面 18接触可接触配合。 所有接触部 251 可以相对于所述屏 蔽件 20的中心轴线呈放射状。
为避免安装爪 25受到沿本体 10的径向上的挤压（如下述壳体 40的挤压）、 便于 配合安装结构（如下述壳体 40的凹陷部 48 )以限制所述屏蔽件 20的活动 ，所述屏蔽 件 20还包括突出部 23。 该突出部 23沿所述本体 10的径向突出设置在所述套设部 21 的边缘上，也即突出部 23 在垂直于所述本体 10 的轴向的同一横截面上具有大于所述 安装爪 25设置在所述套设部 21的外接圆的面积。 为了增强机械强度，所述屏蔽件 20 为一体件。 更进一步地，所述屏蔽件 20 采用 金属制成一体件。
下面具体说明本实施例中的同轴连接器组件 101 的组装方式：将所述套设部 21 的 安装通孔 21 1 从所述筒体 1 1 的尾端，且将所述安装爪 25所在的一侧朝向所述屏蔽配 合部 15，再将所述安装缺口 212对准所述阻挡部 1 1 1 且将所述套设部 21 移动至越过 所述阻挡部 1 1 1 ，使得所述套设部 21 位于所述阻挡部 1 11 与所述屏蔽配合部 15 之 间。 然后，旋转所述屏蔽件 20，以使得所述安装爪 25移动至对应限位槽 163内。 根据 需要，可以向前继续移动所述屏蔽件 20，以使得所述安装爪 25移动至抵接在所述抵紧 台面 18 上；也可以在安装下述壳体时，通过壳体的推挤（或下压）而使得所述安装爪 25移动至抵接在所述抵紧台面 18上。
本领域技术人员可以想到的是，根据相应的连接需要及屏蔽电磁干扰的需要，不同 的部件结构可以选用金属等导体材料或塑料等绝缘材料制成，其材料的选择不是本发明 重点，在此不再赘述。
需要说明的是，如果没有特别指出 ，在本发明中所提及的 "轴向 "均指的是"沿所述本 体 10 的轴向"。 另外，如果没有特别指出 ，在本实施例中所提及的"前端"或"底端"均指 的是在将所述屏蔽件 20 安装在所述本体 10 的方向上，相应部件的在前方的端部。 另 外，如果没有特别指出 ，在本实施例中提及的 "横截面"均指的是该"与所述本体 10 的中 心轴线垂直的截面"。
