本发明的较佳实施方式 下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。 如图 8 -图 10所示, 本发明提供了一种 USB接口, 其包括翻转接头 21 与旋转接头 22。 翻转接头 21 —端通过翻转轴 23可连接于一数据产品本体 1 , 另一端通 过连接轴 24连接旋转接头 22。翻转接头 21可相对数据产品本体 1进行翻转。 旋转接头 22远离翻转接头 21的一端设置有接入端子 25 , 接入端子 25 上连接设置有接地结构 26。该接地结构 26包括连接接入端子 25的接地弹脚 261 ,该接地弹脚 261连接旋转接头 22的接地结构 26的金属壳体,且连接轴 24与翻转接头 21也釆用金属材料, 从而使得本发明接口外部结构形成有效 接地, 对穿行其中的线缆 27带来的电磁干扰形成屏蔽。 接入端子 25通过线缆 27通讯连接数据产品本体 1 ,线缆 27穿过连接轴 24与翻转接头 21上的孔 211 , 线缆 27均设置在该连接轴 24与孔 211轴心, 而且孔 211跟翻转轴 23有相同轴心,所以在连接轴 24与翻转轴 23旋转及翻 转时,对线缆 27影响最小。接入端子 25在靠近连接轴 24位置上设置有固定 结构 28 , 釆用压片 281压靠在连接轴 24上, 将连接轴 24与接入端子 25固 定在一起。 连接轴 24与旋转接头 22固定连接,与翻转接头 21之间可旋转连接。连 接轴 24转动时, 接入端子 25与连接轴 24同时带动线缆 27转动, 这样线缆 27可以减少对接入端子 58焊盘的拉力, 提高通讯的稳定性及可靠性, 同时 提高本发明使用寿命。 本发明釆用翻转接头 21与旋转接头 22 , 使得数据产品插接到电子产品 上时, 可相对该电子产品产生多种不同的位置关系, 十分灵活, 可根据不同 实际需要选用, 另外本发明接入端子 25上设置接地结构 26, 并进行固定, 且釆用连接轴 24与翻转接头 21之间活动连接的方式, 可有效提高本发明通 讯的可靠性与稳定性。 本发明中, 翻转接头 21内设置有翻转到位结构 3 , 翻转到位结构 3如图 12所示, 包括翻转凹槽 31、 翻转到位小球 32与翻转到位弹簧 33。 翻转凹槽 31均勾设置在翻转轴 23表面, 共八个凹槽, 以保证翻转角度 在 45度角上停止。 翻转凹槽 31 内平滑, 凹槽深度应根据翻转到位小球 32 尺寸确定。 为方便加工, 可将该凹槽加工为通槽。 翻转到位小球 32形状与翻转凹槽 31相配,设置在连接翻转轴 23的翻转 到位孔道 34中,翻转到位小球 32两端分别顶靠翻转凹槽 31与翻转到位弹簧 33。 翻转到位小球 32可部分放置在翻转凹槽 31中, 在进行翻转时, 该翻转 到位小球 32可随翻转到位孔道 34相对翻转凹槽 31位置转动。 翻转到位弹簧 33设置在翻转到位孔道 34中,翻转到位弹簧 33—端固定, 另一端通过连接件推靠翻转到位小球 32。 翻转到位弹簧 33向翻转到位小球 32施加复位力, 从而实现翻转到位停止功能。 本发明中, 连接轴 24与翻转接头 21之间设置有旋转到位结构 4, 旋转 到位结构 4与翻转到位结构 3相同, 如图 12所示。 其中, 连接轴 24与旋转 到位结构 4如图 11所示。 旋转到位结构 4包括旋转凹槽 41、 旋转到位小球 42与旋转到位弹簧 43。 旋转凹槽 41均勾设置在连接轴 24表面, 共八个凹槽, 以保证旋转角度 在 45度角上停止。 旋转凹槽 41 内平滑, 凹槽深度应根据旋转到位小球 42 尺寸确定。 为方便加工, 可将该凹槽加工为通槽。 旋转到位小球 42形状与旋转凹槽 41相配,设置在连接连接轴 24的旋转 到位孔道 44中,旋转到位小球 42两端分别顶靠旋转凹槽 41与旋转到位弹簧 43。 旋转到位小球 42可部分放置在旋转凹槽 41中, 在进行旋转时, 该旋转 到位小球 42可随旋转到位孔道 44相对旋转凹槽 41位置转动。 旋转到位弹簧 43设置在旋转到位孔道 44中,旋转到位弹簧 43—端固定, 另一端通过连接件推靠旋转到位小球 42。 旋转到位弹簧 43向旋转到位小球 42施加复位力, 从而实现旋转到位停止功能。 不论翻转到位结构 3还是旋转到位结构 4, 均可以使得在使用本发明时 旋转及翻转时产生一个停顿, 让使用者有明显的手感。 另外, 更重要的是由 于釆用了翻转到位小球 32和旋转到位小球 42, 在翻转与旋转过程中, 以滚 动摩擦代替了原有的滑动摩擦, 大大减小了磨损, 有效提高了使用寿命。 本发明中,连接轴 24与翻转接头 21之间还设置有用于限制旋转接头 22 相对翻转接头 21旋转角度的限位结构 29。该限位结构 29限定旋转角度最大 为 90度, 在实现一周旋转的同时, 避免左右旋转过大。 如图 11所示, 该限 位结构 29可通过在连接轴 24上设置限位台实现, 在连接轴 24与翻转接头 21发生相对旋转时, 该限位台可限制旋转角度。 本发明中在连接轴 24与翻转接头 21之间设置限位结构 29,可有效限制 旋转接头 22相对翻转接头 21旋转角度,避免通讯线缆 27由于旋转接头过度 旋转而导致缠绕, 甚至拉断, 造成不必要的损失。 如图 1 -图 7所示, 本发明还包括一种具有 USB接口的数据产品, 该数 据产品包括数据产品本体 1与 USB接口 2。 其中,数据产品本体 1相应位置上设置有与 USB接口 2相配的凹槽 11。 方便在收藏状态时将该 USB接口 2旋转收藏在该凹槽 11中,不但美观便携, 还可对该 USB接口 2进行保护。 旋转接头 22可相对于翻转接头 21旋转, 从而使用户方便选择数据产品 插入的角度;翻转接头 21可相对于数据产品本体 1翻转,可方便用户调整数 据产品的角度。
USB接口 2结构如上所述, 在此不再赘述。 本发明各种状态结构如图 1 -图 7所示, 显示了本发明的灵活使用及极强的适应能力, 可应用于各种狭 窄空间。 另外, 这些不同的使用状态还可提高本发明的美观性, 提高使用者 的兴趣。 本发明中, 线缆 27包括 4根同轴线缆, 4根同轴线缆外还裹覆一层屏蔽 材料。 釆用该结构, 可以进一步提高屏蔽能力。 综上所述, 以上仅为本发明的较佳实施例而已, 并非用于限定本发明的 保护范围, 因此, 凡在本发明的精神和原则之内所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
工业实用性 本发明釆用翻转接头与旋转接头, 使得数据产品插接到电子产品上时, 可相对该电子产品产生多种不同的位置关系, 十分灵活, 可根据不同实际需 要选用。 本发明接入端子上设置接地结构, 并进行固定, 且釆用连接轴与翻 转接头之间活动连接的方式, 可有效提高本发明通讯的可靠性与稳定性。 本 发明中翻转接头内及连接轴与翻转接头之间均釆用到位结构, 可方便本发明 旋转到位及翻转到位, 扩展使用功能, 增强使用中到位的稳定性。 本发明中 在连接轴与翻转接头之间设置限位结构, 可有效限制旋转接头相对翻转接头 旋转角度, 避免通讯线缆由于旋转接头过度旋转而导致缠绕, 甚至拉断, 造 成不必要的损失。
