Description

芯片接座和粉盒
本发明涉及打印机用的一种芯片接座，以及与该芯片接座配套使用的粉盒。本发明基于申请日为2013年12月23日、申请号为201310719200.8的中国发明专利申请，该申请的内容作为与本发明密切相关的参考文献引入本文。
打印机的机壳上设置打印机接座，打印机接座上的电触点与打印机主板电连接。通常，打印机接座上的电触点为针形电触点，其相对打印机接座上的条状凸台可滑动地设置，该条状凸台具有一对平行的平面。粉盒的盒体上固定地设置有能与针形电触点构成电连接的芯片。芯片通常存储有粉盒容量、碳粉颜色，碳粉组分和碳粉余量等信息。当芯片与打印机主板电连接且建立稳定通讯时，打印机才能持续地执行打印操作。
现有打印机接座上的针形电触点不仅有针形的电触点，还有片形的电触点或弯曲金属条等。
粉盒具有动力接收头，打印机具有动力驱动头，粉盒装入打印机后动力驱动头驱动动力接收头，动力接收头通过齿轮等传动构件带动粉盒内的搅拌架、显影辊和感光鼓等组件工作。因此在驱动过程中粉盒必然会发生震动，固定在粉盒上的芯片也随粉盒发生震动，芯片与打印机接座上的针形电触点的电连接的稳定性较低。
另一方面，芯片的存储和运输要求较粉盒盒体高，优选的应该使用含铝铂的防静电袋进行封装，但由于芯片固定地设置在盒体上，若用含铝铂的防静电袋对粉盒整体进行封装，生产成本将变得较高。
再者，直接成型在芯片上的电触点一般较薄且不耐磨，一旦损坏难以修复，而且芯片反复使用容易导致芯片上的电触点磨损。
打印机接座上的针形电触点与芯片上的平面式的电触点是点面接触，针形电触点依靠其自身的或设置在其端部弹簧的弹性维持其与平面式的电触点的电连接，一旦该弹性有所损失，也使二者的电连接变得极其不稳定。
本发明的主要目的在于提供一种可提高芯片与打印机接座电触点电连接的稳定性，有助于降低生产成本和提高芯片电触点寿命的芯片接座；
本发明的另一目的在于提供一种采用了上述芯片接座的粉盒。
为实现上述主要目的，本发明的芯片接座包括壳体、芯片和导电片，芯片固定在壳体上，导电片固定在壳体上，导电片的第一端与芯片上的电触点电连接，第二端用于与打印机接座上的电触点电连接，壳体上设置有用于与打印机的机壳配接的连接部。
进一步的方案是，导电片呈U形，导电片的底部作为导电片第一端，导电片的两个臂部作为导电片的第二端。导电片的第二端为两个臂部，可以很好地咬合打印机接座上的针形的电触点，形成可靠性极高的电连接。即便针形的电触点一侧的弹性有所损失，U形的导电片仍然可以与针形的电触点有效地咬合，保证稳定的电连接。
更进一步的方案是，壳体具有一腔体，腔体的开口上设置有一对平行的对准板，芯片位于腔体的底部。平行的对准板可以与打印机接座上的条状凸起上的一对平行的平面配合，实现芯片接座的精确定位。
更进一步的方案是，导电片的两个臂部，分别设置有卡片；腔体的壁上设置有与卡片配合的卡位。捏住导电片的两个臂部即可轻松的把导电片推入腔体内，当导电片推到位后，开片卡住腔体壁上的卡位，导电片的第一端与芯片上的电触点构成稳定的电连接。只需捏住导电片的两臂部，使开片脱离卡位即可取出导电片。导电片的装卸皆为简单，便于更换。
更进一步的方案是，两个臂部作为连接部。通过两臂部与打印机针形或片形的电触点的咬合来固定芯片接座，芯片接座结构简单，易于生产，成本低，安装方便。
另一更进一步的方案是，壳体上的对准板作为连接部。芯片接座结构简单，易于生产，成本低，安装方便。
为实现本发明的另一目的，本发明的粉盒包括盒体，盒体上设有避让凹槽，用于使上述各种芯片接座的任一个可部分地位于避让槽内。该芯片接座具有壳体和芯片，芯片固定在壳体上，导电片固定在壳体上，导电片的第一端与芯片上的电触点电连接，导电片的第二端用于与打印机接座上的电触点电连接，设置在壳体上的连接部用于与打印机的机壳配接。
该方案的芯片接座作为一个独立的组件，与粉盒的盒体分离且没有任何连接关系，能直接安装固定在打印机的机壳上，粉盒盒体的震动不会直接传递给芯片，提高了芯片与打印机接座上的电触点的电连接的稳定性。可以用含铝铂的防静电袋对其单独封装，有助于降低生产成本。芯片上的电触点与导电片的第一端固定地电连接，芯片上的触点不会因为芯片反复使用而被严重，导电片为专用的导电配件其耐磨性较芯片上的电触点的高，相当于延长了芯片的电触点的寿命。

如图1所示，打印机100的机壳由壳本体110和盖120组成。盖120内侧设置有打印机接座130，接座130上设置有4个条状凸台131，每个凸台131具有一对平行的平面132。每个条状凸台131上分别设置有4根针状的电触点133。方向M为粉盒向打印机内安装的安装方向，打印机100内可以安装四只装有不同颜色碳粉的粉盒。
如图2所示，沿方向M，粉盒200的盒体210的后侧设置有避让凹槽201。
如图3所示，芯片接座400具有壳体410和芯片420。壳体410上设置有4个散热孔411。芯片420上设有4个电触点（不可见）。
如图4所示，芯片接座400的壳体410具有腔体430。腔体430的开口上设置有一对平行的对准板431，对准板431用于与凸台131上的一对平行对准面132配合以定位芯片接座400。腔体430内有4个导电片440。
芯片420上的4个电触点与4个导电片440分别构成电连接。
如图5所示，导电片440大致呈U形。导电片440的底部441作为其第一端与位于腔体430底部的芯片420的电触点421抵接，并构成电连接。导电片440的两臂部442作为第二端用于打印机接座130的电触点133电连接，并向腔体430的开口一侧延伸。导电片440的两个分别成型在两臂部442上的卡片443卡在腔体430的壁上的卡位432内，芯片420和导电片440都被固定在腔体430内，即被固定在壳体410上。
如图6所示，四个芯片接座400安装在打印机100打印机接座130上。导电片440的两臂部442夹紧针形的电触点133（不可见），芯片接座400凭借两臂部442与针形的电触点133之间的摩擦力固定在打印机接座130上，因此，两臂部442作为连接部实现芯片接座400与打印机100的机壳的配接。
如图7所示，粉盒200的盒体210安装在打印机内，芯片接座400安装在盖120的打印机接座上，盖120相对打印机的壳本体110处于关闭状态。芯片接座400部分地位于盒体210的避让凹槽201内，但是芯片接座400与盒体210分离，即二者之间不存在任何直接连接的关系。
本发明不限于把两臂部442作为连接部，还可以把壳体410上的平行对准板431作为连接部，通过对准板431与凸台131上的平行平面132的连接把芯片接座400固定在打印机100的机壳上。当然，连接部不限于两臂部和平行对准板，还可以是卡扣、销钉或螺钉等；连接部与打印机的机壳的配接方式不限于过盈配合，还可以粘接或焊接等。
本发明不限于通过卡片和卡位的配合将导电片和芯片进行固定，还可以通过铆接，螺钉连接等方式对导电片和芯片进行固定。
本发明芯片接座作为一个独立的组件，能直接安装固定在打印机的机壳上而不需要与粉盒的盒体发生任何连接关系，粉盒盒体的震动不会直接传递给芯片。可以用含铝铂的防静电袋对其单独封装，有助于降低生产成本。芯片上的电触点与导电片的第一端固定地电连接，芯片上的触点不会因为芯片反复使用而被严重，导电片为专用的导电配件其耐磨性较芯片上的电触点的高，相当于延长了芯片的电触点的寿命。
