本申请要求于 2009 年 11 月 11 日提交中国专利局、 申请号为 200920179928.5 , 发明名称为"设有插头的电子设备"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
本实用新型属于涉及电子技术领域， 具体涉及一种设有插头的电子设 备。 背景技术
随着电子技术的不断发展， U盘等各种设有插头的电子设备已经成为人 们日常生活、 平时办公不可缺少的电子设备之一。
如图 1所示， 现有的设有插头的电子设备， 包括开设有端口 1的机壳 2、 穿设于端口 1上的插头 3以及位于机壳 2内且与插头 3电连接的电路板 4， 电路板 4与插头 3相固连且其与机壳 2之间设有锁定结构 5， 锁定结构 5用 于在插头 3处于伸出端口 1的状态时， 将插头 3锁定住。 锁定结构 5包括设 于机壳 2内壁上的止位槽 15、 与电路板 4固连的支架 16以及一端延伸出机 壳 2的按钮 8， 机壳 2上开设有与插头 3缩回或伸出端口 1的方向相平行的 滑槽， 按钮 8延伸出机壳 2的一端可在滑槽内滑动， 按钮 8位于机壳 2内的 一侧固设有与止位槽 15形状相适配的止位部 80，按钮 8远离止位部 80的一 端嵌于支架 16内， 且该端与支架 16之间固设有弹簧 17， 弹簧 17的弹力方 向朝接近滑槽的方向延伸。
当需要使用该设有插头的电子设备时，朝接近端口 1的方向推动按钮 8， 按钮 8便可通过支架 16带动电路板 4以及插头 3沿着滑槽朝接近端口 1的方 向滑动， 直至插头 3处于伸出端口 1 的状态时， 在弹簧 17的作用下按钮 8 上的止位部 80刚好被弹入止位槽 15内， 此时， 按钮 8、 电路板 4以及插头 3 均被止位部 80与止位槽 15所构成的配合结构锁住了； 使用完毕该设有插头 的电子设备之后， 可按动按钮 8压缩弹簧 17并将按钮 8的止位部 80压出止 位槽 15， 此时， 朝远离端口 1的方向推动按钮 8， 便可将插头 3推回， 直至 使插头 3处于缩回端口 1的状态。
本发明人在实现本实用新型的过程中发现， 现有技术至少存在以下技术 问题： 如图 1所示的插头 3处于伸出端口 1的状态时， 锁定结构 5会将插头 3锁定住， 使其位置固定、 无法运动， 当无意间将插头 3处于伸出端口 1 的 状态的设备掉落在地上并撞击到插头 3时， 或无意间碰撞到已经插接于插槽 上的设备时， 插头 3会承受到沿插头 3缩回端口 1的方向的力的撞击， 该撞 击力通常会大于人们在插槽上插接插头 3时对插头 3所施加的推力， 且该撞 击力比较突然， 受力点通常也比较集中， 所以易导致插头 3损坏。 实用新型内容
本实用新型实施例提供了一种设有插头的电子设备， 解决了现有的设有插 头的电子设备的插头处于伸出端口的状态时， 承受到沿插头缩回端口的方向的 力的撞击时， 插头极易损坏的技术问题。
为达到上述目的， 本实用新型的实施例采用如下技术方案：
该设有插头的电子设备， 包括开设有端口的机壳、 穿设于所述端口上的插 头以及位于所述机壳内且与所述插头电连接的电路板， 所述插头与所述机壳之 间设有锁定机构， 所述锁定机构用于在所述插头处于伸出所述端口的状态时， 将所述插头锁定住， 所述锁定机构在所述插头承受到沿所述插头缩回所述端口 的方向的力的撞击时， 会自动失效。
与现有技术相比， 本实用新型所提供上述技术方案中具有如下优点： 由于本实用新型实施例中锁定机构在插头 7|受到沿插头缩回端口的方向的 力的撞击时， 会自动失效， 当无意间将插头处于伸出端口的状态的设备掉落在 地上并撞击到插头时， 或无意间碰撞到已经插接于插槽上的设备时， 锁定机构 会自动失效， 锁定机构自动失效之后， 插头便可沿插头缩回端口方向滑动， 在 该撞击力的作用下， 插头会沿插头缩回端口的方向滑动回机壳内， 撞击力越大， 则插头沿插头缩回端口的方向缩回的距离也会越大， 从而对撞击力起到了緩沖 作用， 避免了撞击力对插头造成损坏， 所以解决了现有的设有插头的电子设备 的插头处于伸出端口的状态时， 承受到沿插头缩回端口的方向的力的撞击时， 插头极易损坏的技术问题。 附图说明
为了更清楚地说明本实用新型实施例的技术方案， 下面将对实施例中所 需要使用的附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本实 用新型的一些实施例， 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。

下面将结合本实用新型实施例中的附图， 对本实用新型实施例中的技术方 案进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本实用新型一部分实 施例， 而不是全部的实施例。 基于本实用新型中的实施例， 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， 都属于本实用新型 保护的范围。
本实用新型实施例提供了一种结构简单、 可靠性好且处于伸出端口的状态 的插头不易被撞击而损坏的设有插头的电子设备。
如图 2、图 3和图 4所示，本实用新型实施例所提供的设有插头的电子设备， 包括开设有端口 1的机壳 2、穿设于端口 1上的插头 3以及位于机壳 2内且与插 头 3电连接的电路板 4， 插头 3与机壳 2之间设有如图 5所示的锁定机构 5， 锁 定机构 5用于在插头 3处于伸出端口 1的状态时， 将插头 3锁定住， 锁定机构 5 在插头 3承受到沿插头 3缩回端口 1的方向的力的撞击时， 会自动失效。
由于本实用新型实施例中如图 5所示的锁定机构 5在插头 3承受到沿插头 3 缩回端口 1 的方向的力的撞击时， 会自动失效， 当无意间将插头 3处于伸出端 口 1 的状态的设备掉落在地上并撞击到插头 3时， 或无意间碰撞到已经插接于 插槽上的设备时， 锁定机构 5会自动失效， 锁定机构 5 自动失效之后， 插头 3 便可沿插头 3缩回端口 1方向滑动， 在该撞击力的作用下， 插头 3会沿插头 3 缩回端口 1方向滑动回机壳 2内， 撞击力越大， 则插头 3沿插头 3缩回端口 1 方向缩回的距离也会越大， 从而对撞击力起到了緩沖作用， 避免了撞击力对插 头 3造成损坏， 所以解决了现有的如图 1所示设有插头的电子设备的插头 3处 于伸出端口 1的状态时， 承受到沿插头 3缩回端口 1的方向的力的撞击时， 插 头 3极易损坏的技术问题。
如图 5所示的锁定机构 5包括与如图 2所示插头 3固连且朝机壳 2的一个 侧壁 20延伸如图 4和图 7所示的弹力筋条 6、 固设于弹力筋条 6远离插头 3— 端的定位凸起 7以及与定位凸起 7固连的按钮 8， 其中：
如图 3所示的侧壁 20上开设有与插头 3缩回或伸出端口 1的方向相平行的 滑道 9， 按钮 8延伸出滑道 9且可在滑道 9滑动；
侧壁 20上还开设有如图 4所示的定位槽 10，定位凸起 7远离插头 3的一侧 设有逐渐降低如图 5和图 7所示的坡面 1 1，定位凸起 7嵌于定位槽 10内且坡面 1 1与定位槽 10的内壁相抵靠。
插头 3处于伸出端口 1的状态时， 定位凸起 7嵌于定位槽 10内且坡面 11 与定位槽 10的内壁相抵靠， 由于弹力筋条 6朝机壳 2的一个侧壁 20延伸， 所 以弹力筋条 6的弹力方向也是朝侧壁 20延伸的， 在弹力筋条 6的弹力作用下， 定位凸起 7被有力的顶住且嵌于定位槽 10内， 在定位槽 10的阻挡之下， 处于 伸出端口 1的状态的插头 3会被锁定住；
当无意间将插头 3处于伸出端口 1的状态的设备掉落在地上并撞击到插头 3 时， 或无意间碰撞到已经插接于插槽上的设备时， 由于定位凸起 7上逐渐降低 的坡面 1 1与定位槽 10的内壁相 4氏靠， 所以定位槽 10与定位凸起 7的坡面 1 1 相抵靠的内壁必然也为倾斜面， 而在撞击力的作用下， 定位槽 10内壁的倾斜面 对定位凸起 Ί会施加一个反作用力， 该反作用力可以分解出一个与弹力筋条 6 的弹力相反的力， 在该力的作用下定位凸起 7会脱出定位槽 10， 同时在撞击力 的作用下会沿插头 3缩回端口 1方向滑动回机壳 2内， 从而緩沖了撞击力。
电路板 4与插头 3相固连， 弹力筋条 6与电路板 4相固连。 电路板 4表面 积比较大， 在电路板 4上设置插头 3以及弹力筋条 6操作空间均比较大， 同时， 电路板 4与插头 3相固连时， 插头 3与电路板 4之间的电连接结构更为可靠。 当然， 本实施例中电路板 4与插头 3之间也可以仅通过导线电连接， 此时， 弹 力筋条 6也可以直接与插头 3相固连。
弹力筋条 6以端口 1的轴向中心线对称设置于电路板 4上， 定位凸起 7呈 条形且设于对称设置的弹力筋条 6之间， 按钮 8位于定位凸起 7的中间。 这种 结构中不仅对称设置的每个弹力筋条 6所承受的力均比较均衡， 弹力更好， 而 且弹力筋条 6与定位凸起 7之间的连接性比较好。
定位凸起 7顶部的横截面呈梯形， 其底边较大且与弹力筋条 6相固连。 这 种结构的定位凸起 7与定位槽 10远离插头 3的内壁以及接近插头 3的内壁之间 的抵靠面均为坡面 1 1，插头 3承受到沿插头 3缩回端口 1的方向的力的撞击时， 定位槽 10接近插头 3的内壁在定位凸起 7从定位槽 10内脱出时，对定位凸起 7 所施加的阻挡力更小， 所以更有利于锁定机构 5 自动失效。
如图 2所示的侧壁 20上还设有如图 6所示的滑动槽 12，如图 3所示的滑道 9开设于滑动槽 12的底面上， 按钮 8固连有呈板状的滑块 13， 滑块 13嵌于滑 动槽 12内且其可在滑动槽 12内沿滑道 9的延伸方向滑动。
呈板状的滑块 13不仅增大了按钮 8的表面积， 使得人手推动按钮 8时， 施 力区域更大， 手感更好， 而且滑块 13也使得按钮 8滑动过程中更平稳、 滑动方 向更准确。
侧壁 20的内侧即接近弹力筋条 6的一侧还开设有与定位凸起 7顶部形状相 适配的止退槽 18。 当插头 3处于缩回端口 1的状态时， 定位凸起 7的顶部正好 嵌于止退槽 18内。止退槽 18在插头 3处于缩回端口 1的状态时容纳定位凸起 7 的顶部， 避免弹力筋条 6—直处于受侧壁 20的内侧挤压的状态而出现弹力下降 乃至无法复原的情况发生。
插头 3周围的电路板 4上固设有呈框状如图 7所示的连接座 14， 弹力筋条 6与连接座 14相固连。
呈框状的连接座 14增大了电路板 4与插头 3之间以及电路板 4与弹力筋条 6之间的结合面积，使得插头 3与电路板 4之间以及电路板 4与弹力筋条 6之间 彼此连接的更为可靠。
如图 7所示的连接座 14、 弹力筋条 6以及按钮 8均为塑胶材料制成。 塑胶 材料成本低廉且其弹力可以满足弹力筋条 6 的要求， 同时， 塑胶材料的连接座 14、 弹力筋条 6以及按钮 8便于采用焊接或一次成型工艺制造， 比较方便制造。
侧壁 20为机壳 2上正投影面积最大的侧壁。 设有插头的电子设备如图 2所 示的机壳 2通常结构比较简单， 机壳 2上正投影面积最大的侧壁通常也为其表 面积比较大的侧壁， 所以在该侧壁 20上设置各种部件、 开设各种孔或槽时， 操 作空间大。
本实施例中如图 2所示的机壳 2呈长方体状， 机壳 2上正投影面积最大的 侧壁 20为其表面积最大的侧壁。 当然， 机壳 2的形状也可以设计为椭球形或棱 柱状等多种形状。
该设有插头的电子设备为数据卡或 U盘。 数据卡或 U盘体积较小， 便于携 带， 同时也极易跌落， 所以适宜采用本实用新型实施例所提供的上述技术方案。
以上， 仅为本实用新型的具体实施方式， 但本实用新型的保护范围并不局 限于此， 任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内， 可 轻易想到变化或替换， 都应涵盖在本实用新型的保护范围之内。 因此， 本实用 新型的保护范围应以权利要求的保护范围为准。
