Description

USB接头固定装置
技术领域
本发明涉及一种固定装置，特别是涉及一种防EMI的USB接头固定装置。
背景技术
电子设备在工作时会产生电磁辐射，由此可能会降低整体***的性能，或可能对外部生物或物质产生不良影响，上述现象称为EMI（Electro Magnetic Interference：电磁干扰）。一般防止EMI的方法是在电子设备外部加上适当的屏蔽体，具体在计算机应用领域，计算机机壳的密闭结构即具备防EMI的效果。但是，一般的计算机机体上都会配备多种接口，比如USB接口，这些接口为机体内电子设备产生的电磁波的泄漏提供了可能。
发明内容
鉴于以上内容，有必要提供一种防EMI的USB接头固定装置。
一种USB接头固定装置，包括一用于收容USB接头的收容架及一用于固定所述收容架的固持架，所述收容架的外侧面设有若干向外凸起的抵顶弹片，每一抵顶弹片由所述收容架的内侧向外侧冲压而成，形成一开口，所述固持架的内侧面设有若干向内凸起的抵挡部，所述收容架的抵顶弹片与所述固持架的抵挡部相抵接触，所述抵顶弹片发生弹性形变并覆盖所述抵顶弹片冲设时形成的开口。
优选地，所述收容架为一体成型的中空壳体，所述收容架的前端和后端开口。
优选地，所述固持架的上下左右内侧面各设有一个所述抵挡部，所述抵挡部具有一平板状的接触面。
优选地，所述抵顶弹片的延伸方向与所述壳体的后端开口方向一致。
优选地，所述抵顶弹片的末端呈折板状，向所述壳体的内侧方向弯折。
优选地，所述壳体的后端上下外表面各设有两个所述抵顶弹片，所述壳体的后端左右外表面各设有一个所述抵顶弹片。
优选地，所述壳体的前端内侧设有若干向内凸起的抵压弹片，所述抵压弹片的末端呈折板状，向所述壳体的外侧方向弯折。
优选地，所述壳体的前端上下内表面各设有两个所述抵压弹片，所述抵压弹片的延伸方向与所述壳体的前端开口方向一致。
优选地，所述壳体的前端左右内表面各设有一个所述抵压弹片，所述抵压弹片的延伸方向与所述壳体的后端开口方向一致。
与现有技术相比，本发明USB接头固定装置的收容架的抵顶弹片与固持架上的抵挡部相抵接触，从而可起到防EMI的作用。

如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
请参阅图1，在本发明的一较佳实施方式中，一种USB接头固定装置，包括一用于收容USB接头的收容架10及一用于固定所述收容架10的固持架20。
请继续参阅图2，所述收容架10为一体成型的中空壳体，所述收容架10的前端和后端开口。所述收容架10的前端开口用作接收USB设备插头的入口，所述收容架10的后端开口用于容纳连接主板USB芯片的印刷电路板（PCA板）。所述收容架10的后端上下外表面各设有两个向外凸起的抵顶弹片101，所述收容架10的后端左右外表面各设有一个向外凸起的抵顶弹片101。所述抵顶弹片101由所述收容架10的内侧向外侧冲压而成，形成一开口。所述抵顶弹片101的延伸方向与所述收容架10的后端开口方向一致。所述抵顶弹片101的末端呈折板状，向所述收容架10的内侧方向弯折。所述收容架10的前端上下内表面各设有两个向内凸起的抵压弹片102，所述抵压弹片102的延伸方向与所述收容架10的前端开口方向一致。所述抵压弹片102的末端呈折板状，向所述收容架10的外侧方向弯折。所述收容架10的前端左右内表面各设有一个向内凸起的抵压弹片103，所述抵压弹片103的延伸方向与所述收容架10的后端开口方向一致。所述抵压弹片103的末端呈折板状，向所述收容架10的外侧方向弯折。
所述固持架20设有一中空腔体，前端和后端各具有一开口。所述中空腔体的上下左右内侧面各设有一个向内凸起的抵挡部201，所述抵挡部201具有一平板状的接触面。
请参阅图3，组装所述USB接头固定装置时，将所述收容架10的后端开口对应所述固持架20的前端开口，所述收容架10的上外表面的所述抵顶弹片101对应所述固持架20的上内表面的所述抵挡部201，所述收容架10的下外表面的所述抵顶弹片101对应所述固持架20的下内表面的所述抵挡部201，所述收容架10的左外表面的所述抵顶弹片101对应所述固持架20的左内表面的所述抵挡部201，所述收容架10的右外表面的所述抵顶弹片101对应所述固持架20的右内表面的所述抵挡部201，将所述收容架10向所述固持架20推进，所述收容架10上的抵顶弹片101发生弹性形变，与所述固持架20上的抵挡部201相抵接触，所述抵顶弹片101覆盖所述抵顶弹片101冲设时形成的开口。此时，所述收容架10固定于所述固持架20中，由于所述收容架10的抵顶弹片与所述固持架20上的抵挡部相抵接触，可以起到防EMI的作用。
对本领域的技术人员来说，可以根据本发明的发明方案和发明构思结合生产的实际需要做出其他相应的改变或调整，而这些改变和调整都应属于本发明权利要求的保护范围。
