具体实施方式
下面结合图4至图9对本公开提供的技术方案进行更为详细的阐述。
参见图4，本公开公开了一种控制器，包括外壳、PCB板40和端口60，外壳具有安装空间，安装空间内安装有PCB板40，外壳内还设置有与PCB板40相匹配的第一限位部22，PCB板40上还设置有端口60，第一限位部22用于限制PCB板40在端口60插接方向上的位移。本公开的控制器通过在壳体10上设置第一限位部22，从而限制PCB板40在端口60插接方向上的位移，从而在端口60在插接时，可以通过第一限位部22限制PCB板40的位移，从而有效防止PCB板40松动。
参见图8，在一些实施例中，端口60的插接方向与PCB板40所在平面平行，第一限位部22用于限制PCB板40在其自身所在平面内的位移。本公开一些实施例提供的控制器通过在壳体10上设置第一限位部22，从而限制PCB板40在其自身所在平面内的位移，再将端口60的插接方向设置为与PCB板40所在平面平行，从而在端口60在插接时，可以通过第一限位部22限制PCB板40的位移，从而有效防止PCB板40松动。
参见图5至图7，在一些实施例中，外壳包括壳体10、第一盖板20和第二盖板30，第二盖板30与第一盖板20相对设置，且第二盖板30、第一盖板20和壳体10围成密闭的安装空间。
参见图7，在一些实施例中，壳体10上对应PCB板40设置有导向槽11，导向槽11沿PCB板40的安装方向设置，PCB板40沿导向槽11插入壳体10内。通过设置导向槽11，可以引导PCB板40的插入方向，方便PCB板40的安装。壳体10上对应端口60位置设置有开口12。端口60穿设开口12并凸出于壳体10表面。安装时，将PCB板40沿安装方向推入壳体10内的极限位置。此时，将PCB板40往端口60一侧推，即可将端口60露出，解决了端口60凸出对安装过程造成干涉的问题，方便了后续端口的插接操作。安装过程不涉及对PCB板40的按压操作，减少了PCB板40受到的应力、应变。
参见图4和图5，在一些实施例中，第一盖板20上设置有第一限位部22，PCB板40上设置有第二限位部，第一限位部22与第二限位部限位配合。具体地，第一盖 板20上设置有安装部21，安装部21为安装板。安装板上设置有第一限位部22，PCB板40通过螺钉固定连接在安装板上。采用螺钉连接的方式，不需要按压PCB板40，减少了PCB板40受到的应力、应变。第一盖板20通过利用螺钉先锁紧PCB板40的一侧，使PCB板40与第一盖板20成为一体，可以更好地对准壳体10的导向槽11，方便PCB板40安装到壳体10内。并且由于PCB板40与第一盖板20成为一体，安装时，将PCB板40沿安装方向推入壳体10内的极限位置后，第一盖板20会比壳体10的高出一段距离。此状态下，通过推动第一盖板20，更方便地将端口60露出，安装过程更加流畅快捷。
并且通过第一限位部22和第二限位部配合，更利于限制PCB板40在其自身所在平面内的位移，在具体实施过程中，第一限位部22为定位柱或定位孔，第二限位部为定位孔或定位柱。通过限位孔和限位柱相互配合，在起到限位作用的同时，将PCB板40安装到安装板的过程中，也起到定位作用，方便安装。
参见图4和图6，在一些实施例中，第二盖板30上设置有卡槽31和止回筋条32，卡槽31与PCB板40限位配合，止回筋条32抵接在PCB板40上。止回筋条32的设置位置限制PCB板40在端口60插入方向产生的位移。
具体的，止回筋条32设置第二盖板30上并对应PCB板40远离端口60的一侧。通过设于第二盖板30的卡槽31和止回筋条32，将PCB板40完全推入主体后，卡槽31夹紧PCB板40，止回筋条32压紧PCB板40远离端口60的侧面上，以防PCB板40和第二盖板30被在端口60插入方向上产生的外力推回，保证PCB板40受力平衡，不容易发生应力变形。同时，还使得第一、第二盖板与壳体10之间的螺钉孔对准，方便安装。
另外，本公开的一些实施例利用螺钉将PCB板40的一侧锁紧在第一盖板20，利用第二盖板30的止回筋条32、卡槽31将PCB板40的另一侧压紧，通过第一盖板20和第二盖板30在结构上相互配合，改善设置彻底解决了PCB板40安装松动的问题。
在一些实施例中，卡槽31的结构可以采用多种形式。例如：卡槽31由在第二盖板30上间隔设置的两个支撑筋条形成，PCB板40插设在两个支撑筋条中间且被两个支撑筋条夹紧。
可以理解的是，在一些实施例中，在安装时，先将第一盖板22与PCB板40螺钉连接，两者一起推入壳体10内。PCB板40安装在壳体10后，推至极限位置，将PCB板40往下推，将端口60穿过开口12并凸出于壳体10表面，参见图9。再将第二盖 板30安装在壳体10上，支撑筋条夹紧PCB板40，止回筋条32会压紧PCB板40的侧面。第一盖板20和第二盖板30安装螺钉。上述安装过程，不按压PCB板40，减少了PCB板40受到的应力、应变。
在本公开的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开保护范围的限制。
最后应当说明的是:以上实施例仅用以说明本公开的技术方案而非对其限制；尽管参照较佳实施例对本公开进行了详细的说明，所属领域的普通技术人员应当理解：依然可以对本公开的具体实施方式进行修改或者对部分技术特征进行等同替换；而不脱离本公开技术方案的精神，其均应涵盖在本公开请求保护的技术方案范围当中。
