Description

一种防水耳机座 技术领域
本发明涉及电子产品领域， 具体涉及一种防水耳机座。
背景技术
随着电子产品不断向轻薄及多功能发展， 耳机座也在不断发展与之相适 应。 目前， 在手机、 移动互联网设备（Mobile Internet Devices, MID ), 掌上 电脑、 MP3、 MP4等 ^艮多的防水电子产品中， 耳机座自身是不防水的。 因为， 现有耳机座的接触端子是从耳机座的底面或侧面的塑胶孔伸出， 并与电路板 信号端接触的。 当水进入耳机座的耳机插孔之后， 水可以顺着耳机座的底面 或侧面的塑胶孔进入电子产品内部的电路板中。 为了实现耳机座防水， 现有 技术中一般在耳机座内增加保护塞或增加结构件进行围堵， 防止水顺着耳机 座的底面或侧面的塑胶孔进入电子产品内部。
实践中发现， 在耳机座内增加保护塞或增加结构件虽然可以起到防水作 用， 但是这种方式会导致耳机座的尺寸增加， 不利于电子产品做薄。
发明内容
针对上述缺陷， 本发明实施例提供了一种防水耳机座， 该耳机座自身具 备防水功能。
一种防水耳机座， 包括：
耳机座壳体、 接触端子和挡板；
所述耳机座壳体设置有一贯穿所述耳机座壳体的空间，所述空间用于容纳 耳机插头；
所述挡板位于所述耳机座壳体尾部开口，并且与所述耳机座壳体尾部开口 紧密接触， 将所述耳机座壳体尾部开口密封；
所述接触端子紧贴所述空间内壁， 并从所述挡板上设置的孔穿出； 所述孔 的形状与所述接触端子的截面相匹配， 使得所述孔被所述接触端子阻塞。
本发明实施例中，防水耳机座的耳机座壳体设置有一贯穿所述耳机座壳体 的用于容纳耳机插头的空间，同时位于耳机座壳体尾部开口的挡板与耳机座壳 体尾部开口紧密接触，将所述耳机座壳体尾部开口密封， 而且紧贴该空间内壁 并从所述挡板上的孔穿出的接触端子将所述孔阻塞，从而可以防水耳机座自身 实现防水功能。本发明实施例提供的防水耳机座内不需要增加保护塞或增加结 构件进行水围堵， 避免了耳机座的尺寸增加， 有利于电子产品做薄。
附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例中所需要使 用的附图作筒单地介绍， 显而易见地， 下面描述中的附图仅仅是本发明实施 例的一些实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动的前 提下， 还可以根据这些附图获得其他的附图。
图 1为本发明实施例提供的一种防水耳机座的仰视图；
图 2为图 1所示的防水耳机座的一种俯视图；
图 3为图 1所示的防水耳机座与电路板接触安装的示意图；
图 4为图 1所示的防水耳机座的另一种俯视图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不 是全部的实施例。 基于本发明中的实施例， 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， 都属于本发明保护的范围。
本发明实施例提供了一种防水耳机座， 该耳机座自身具备防水功能， 有利 于电子产品做薄。 下面通过具体实施例进行说明。
请参阅图 1~图 2, 图 1为本发明实施例的防水耳机座的俯视图， 图 2为图 1 所示的防水耳机座的一种俯视图。 其中， 本发明实施例提供的防水耳机座 可以包括：
耳机座壳体 1、 接触端子 20和挡板 30;
所述耳机座壳体 1设置有一贯穿所述耳机座壳体 1的空间 （ 10 ) , 所述空 间 10用于容纳耳机插头；
所述挡板 30位于所述耳机座壳体 1尾部开口， 并且与所述耳机座壳体 1 尾部开口紧密接触， 将所述耳机座壳体 1尾部开口密封； 所述接触端子 20紧贴所述空间 10内壁， 并从所述挡板 30上设置的孔穿 出； 所述孔的形状与所述接触端子 20的截面相匹配， 使得所述孔被所述接触 端子 20阻塞。
本发明实施例中， 所述挡板 30与所述耳机座壳体 1尾部开口紧密接触具 体是指所述挡板 30形状与所述耳机座壳体 1尾部开口形状相匹配， 在所述挡 板 30位于所述耳机座壳体 1尾部开口的状态下，所述挡板 30可以将所述耳机 座壳体 1尾部开口密封，使得所述耳机座壳体 1尾部实现防水功能。也就是说， 水无法通过所述耳机座壳体 1尾部进入到电子产品内部的电路板中。
本发明实施例中， 所述孔被所述接触端子 20阻塞是指所述孔被所述接触 端子 20的截面完全密封，所述孔与所述接触端子 20截面之间不存在任何缝隙。
本发明实施例中，防水耳机座的耳机座壳体 1设置有一贯穿所述耳机座壳 体 1的用于容纳耳机插头的空间 10, 同时位于耳机座壳体 1尾部开口的挡板 30与耳机座壳体 1尾部开口紧密接触， 将所述耳机座壳体 1尾部开口密封， 而且紧贴该空间 10内壁并从所述挡板 30上的孔穿出的接触端子 20将所述孔 阻塞，从而可以防水耳机座自身实现防水功能。本发明实施例提供的防水耳机 座内不需要增加保护塞或增加结构件进行水围堵， 秉承超薄设计理念，避免了 耳机座的尺寸增加， 有利于电子产品做薄。
作为一种可选的实施方式， 本发明实施例提供的防水耳机座中，耳机座壳 体 1上可以设置至少一个固定件，该固定件用于将耳机座壳体 1与电子产品的 机壳固定， 从而提高耳机座壳体 1安装的稳定性。
举例来说， 如图 1~图 2所示， 本发明实施例提供的防水耳机座中， 耳机 座壳体 1中部可以设置有左固定件 40和右固定件 50。进一步地， 左固定件 40 与右固定件 50对称， 并且左固定件 40、 右固定件 50上分别有螺釘孔 60。
其中， 通过左固定件 40、 右固定件 50上的螺釘孔 60, 耳机座壳体 1与电 子产品的机壳之间可以采用螺釘锁在一起，从而提高耳机座壳体 1安装的稳定 性。
作为一种可选的实施方式， 为了配合机壳的一些特殊结构设置， 左固定件 40和右固定件 50也可以设置在偏向耳机座壳体 1尾部或耳机座壳体 1头部的 其他位置， 本发明实施例不做限定。 作为一种可选的实施方式， 为了配合机壳的一些特殊结构设置，耳机座壳 体 1上可以仅设置左固定件 40或右固定件 50, 只要左固定件 40或右固定件 50能使耳机座壳体 1与电子产品的机壳固定即可， 本发明实施例不做限定。
作为一种可选的实施方式， 为了配合机壳的一些特殊结构设置，耳机座壳 体 1上可以设置至少二个左固定件 40和至少二个右固定件 50, 从而更好地使 耳机座壳体 1与电子产品的机壳固定， 本发明实施例不做限定。
作为一种可选的实施方式， 为了配合机壳的一些特殊结构设置， 左固定件 40上以及右固定件 50上可以设置多个螺釘孔 60, 从而更好地使耳机座壳体 1 与电子产品的机壳固定， 本发明实施例不做限定。
作为一个可选的实施方式， 位于所述耳机座壳体 1尾部开口的挡板 30与 所述耳机座壳体 1尾部开口之间若存在细小的缝隙，则可以采用防水胶对该缝 隙进行密封， 使得水即使流入所述空间 10也无法通过所述耳机座壳体 1尾部 进入到电子产品内部的电路板中。类似地， 若接触端子 20与所述挡板 30上的 孔之间存在细小缝隙，也可以采用防水胶对该缝隙进行密封，从而使得整个耳 机座壳体 1尾部都是一个全密封的结构。
如图 1或图 2所示， 在耳机座壳体 1的尾部设置有一接触板 160。 作为一 个可选的实施方式，接触端子 20从所述挡板 30上的所述孔穿出的部分可以紧 贴设置在耳机座壳体 1尾部的接触板 160的下表面 160A, 该下表面 160A为 与耳机座壳体 1尾部开口在同一侧的表面。 进一步地， 在这种实施方式下， 设 置在耳机座壳体 1尾部的接触板 160的上表面 160B、 耳机座壳体 1尾部的上 表面可以位于同一水平面上， 接触板 160的上表面 160B为与下表面 160A相 对的表面。 通过这种实施方式， 有利于安装了防水耳机座的电子产品做薄。 因 为， 当接触板 160的上表面、 耳机座壳体 1上表面位于同一水平面上时， 可以 使防水耳机座与电路板接触安装后的总厚度最小化，从而有利于安装了防水耳 机座的电子产品做薄。
请一并参阅图 3, 图 3为图 1所示的防水耳机座与电子产品内部的电路板 接触安装的示意图。 如图 3所示， 防水耳机座的接触板 160的上表面 160B、 耳机座壳体 1尾部的上表面位于同一水平面上，防水耳机座与电路板接触安装 后， 紧贴在防水耳机座的接触板 160的下表面 160A的接触端子 20与电路板 信号端连接，而位于电路板一侧的防水耳机座的耳机座壳体 1与电路板的重叠 厚度最大，从而使得防水耳机座与电路板接触安装后， 电路板与防水耳机座的 总厚度最小， 有利于安装了防水耳机座的电子产品做薄。
举例来说， 当接触板 160的上表面 160B低于耳机座壳体 1尾部的上表面 时， 防水耳机座与电路板接触安装后， 防水耳机座与电路板的重叠厚度较小， 从而使得防水耳机座与电路板接触安装后的总厚度较大，不利于安装了防水耳 机座的电子产品做薄。
可见，在不考虑电子产品进一步做薄的情况下，设置在耳机座壳体 1尾部 的接触板 160的上表面 160B也可以低于耳机座壳体 1尾部的上表面， 本发明 实施例不作限定。 因为， 在这种方式下， 防水耳机座自身仍然可以实现防水功 能， 防水耳机座内不需要增加保护塞或增加结构件进行水围堵。
本发明实施例提供的防水耳机座中， 接触端子 20可以包括麦克风端子、 接地端子、 右声道端子、 左声道端子以及开关端子。 其中， 麦克风端子一般布 局在耳机插孔底壁， 而接地端子、 右声道端子、 左声道端子以及开关端子一般 布局在耳机插孔侧壁。 实际应用中， 麦克风端子与耳机插孔开口边缘的距离最 小， 图 1中可以看得见的接触端子即为麦克风端子； 其中， 接地端子与耳机插 孔开口边缘的距离略大于麦克风端子与耳机插孔开口边缘的距离；右声道端子 与耳机插孔开口边缘的距离略大于接地端子与耳机插孔开口边缘的距离；左声 道端子与耳机插孔开口边缘的距离略大于右声道端子与耳机插孔开口边缘的 距离；而开关端子与耳机插孔开口边缘的距离略大于左声道端子与耳机插孔开 口边缘的距离。
作为一种可选的实施方式， 上述的麦克风端子、 接地端子、 右声道端子、 左声道端子以及开关端子从挡板 30上的所述孔穿出的部分可以排成一排， 如 图 2所示。 即上述的麦克风端子、 接地端子、 右声道端子、 左声道端子以及开 关端子从挡板 30上的孔穿出的部分可以排成一排紧贴在耳机座壳体 1尾部设 置的接触版 160的下表面 160A。
作为一种可选的实施方式， 上述的麦克风端子、 接地端子、 右声道端子、 左声道端子以及开关端子从挡板 30上的所述孔穿出的部分也可以排成至少二 排， 如图 4所示， 图 4为图 1所示的防水耳机座的另一种俯视图。 即上述的麦 克风端子、 接地端子、 右声道端子、 左声道端子以及开关端子从挡板 30上的 所述孔穿出的部分可以排成至少二排紧贴耳机座壳体 1尾部设置的接触板 160 的下表面 160A。
作为一种可选的实施方式， 上述的麦克风端子、 接地端子、 右声道端子、 左声道端子以及开关端子从挡板 30上的所述孔穿出的部分也可以采用其他排 列方式紧贴耳机座壳体 1尾部设置的接触板 160的下表面 160A。 本发明实施 例不作限定。
作为一种可选的实施方式，即上述的麦克风端子、接地端子、右声道端子、 左声道端子以及开关端子从挡板 30上的所述孔穿出的部分穿出的部分可以通 过焊接方式或弹接方式与电路板信号端连接。
如图 1所示， 上述的用于容纳耳机插头的空间 10的开口位于耳机座壳体 1头部截面上， 作为一种可选的实施方式， 耳机座壳体 1头部截面可以为水平 端面或弧形端面， 本发明实施例不作限定， 特别地， 当耳机座壳体 1头部截面 为弧形端面时， 可以使耳机座壳体 1头部截面更好地与机壳外形相匹配，使机 壳外形可以实现弧形化应用， 进一步提高机壳外形的美观程度。
本发明实施例提供的防水耳机座中， 耳机插头直径可以为 2.5mm 或 3.5mm, 本发明实施例不作限定。 本发明实施例提供的防水耳机座可以应用于 手机、 电脑、 MID、 掌上电脑、 MP3、 MP4以及其他需要安装耳机座的电子产 品中。
作为一种可选的实施方式，耳机座壳体 1可以由塑胶材料压制而成，从而 可以防止耳机座壳体 1被水或其他液体腐蚀。
综上所述， 本发明实施例提供的防水耳机座自身可以实现防水功能， 防水 耳机座内不需要增加保护塞或增加结构件进行水围堵，避免了耳机座的尺寸增 加， 有利于电子产品做薄。
以上对本发明所提供的一种防水耳机座进行了详细介绍，对于本领域的一 般技术人员， 依据本发明实施例的思想， 在具体实施方式及应用范围上均会 有改变之处， 综上所述， 本说明书内容不应理解为对本发明的限制。
