Description

单板导向套和具有导向套的单板装置
本公开要求享有2018年11月26日提交的名称为“单板导向套和具有导向套的单板装置”的中国专利申请CN201811429688.X的优先权，其全部内容通过引用并入本文中。
技术领域
本公开涉及网络通信设备的单板技术领域，特别涉及一种单板导向套和具有导向套的单板装置。
背景技术
在电子设备的机箱中，尤其是通讯类设备的机箱上，单板通过与背板对应外置的连接器互插而实现板间通信。
一些情况下机箱单板防误插一般通过在单板和背板上分别设计导向套6和导销7配合实现，如图1所示，导向套6的截面防误插位置为一字结构，导向套6和导销7按一对一配合，插槽和单板配置也成一对一关系，这种方式使系统配置能力受限。例如，如果背板上有8个单板槽位，每个槽位上设置固定方向的导销，两个交换单板，一个监控单板，一个电源单板，则只剩下4个槽位留给业务单板，如果需要增加业务单板以提高系统的配置时，则会受到限制。如果不同单板采用同样的导向套6和导销7配合，则不能起到有效的防误插作用；而通过同一单板现场更换导向套6的形式实现，则会带来工程维护困难，维护成本高，易插错槽位的问题。
发明内容
本公开的主要目的是提供一种单板导向套，旨在其具有防误插功能的同时，增强了单板的适配能力，提高了系统配置的灵活性和易用性，使系统的配置能力提高，且降低了维护成本。
为实现上述目的，本公开提出的单板导向套，包括本体，所述本体的中部设置有插接导销的定位孔，所述定位孔的一端的周侧设置有倾斜台阶，所述定位孔的内壁沿径向延伸设有凸出结构，所述凸出结构包括两个斜面，所述两个斜面连接。
本公开还提出一种具有导向套的单板装置，包括单板和上述的单板导向套，所述导向套通过连接结构与单板相连。
本公开单板导向套包括本体，所述本体的中部设置有插接导销的定位孔，所述定位孔的一端的周侧设置有倾斜台阶，所述定位孔的内壁沿径向延伸设有凸出结构，所述凸出结构包括两个斜面，所述两个斜面连接。

本公开目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
下面结合附图及实施例就本公开的技术方案做进一步的说明。应当理解，此处所描述的实施例仅仅用以解释本公开，并不用于限定本公开。
本公开提出一种单板导向套，能够插接两种不同方向的导销，在具有防误插功能的同时，增强了单板的适配能力，提高了系统配置的灵活性和易用性，使系统的配置能力提高，且改变了传统同一单板更换导向套的方式，降低了维护成本。
参照图2至5b，图2为本公开单板导向套的一实施例的结构示意图；图3为本公开单板 导向套的一实施例的截面结构示意图；图4a为本公开一实施例中第一导向套71与第一导销71配合插接时的截面示意图；图4b为本公开一实施例中第一导向套71与第二导销72配合插接时的截面示意图；图5a为本公开另一实施例中第二导向套62与第二导销72配合插接时的截面示意图；图5b为本公开另一实施例中第二导向套62与第三导销73配合插接时的截面示意图；图6为本公开单板导向套的又一实施例的截面结构示意图；图7为本公开单板导向套的再一实施例的截面结构示意图；图8为本公开单板装置的侧视图；图9为本公开单板导向套的正视图。
在本公开实施例中，该单板导向套包括本体1，所述本体1的中部设置有插接导销7的定位孔2，所述定位孔的一端的周侧设置有倾斜台阶，所述定位孔2的内壁沿径向延伸设有凸出结构3，所述凸出结构3包括两个斜面4，所述两个斜面4连接；如图2和图3所示
本公开技术方案通过采用在本体1的中部设置插接导销7的定位孔2，所述定位孔的一端的周侧设置有倾斜台阶，插接导销于定位孔时，倾斜台阶可起初导向的作用，定位孔2的内壁沿径向延伸设置凸出结构3，且凸出结构可以沿一个轴向连续置于定位孔内壁，或凸出结构沿一个轴向间断的置于孔的内壁，或凸出结构沿一个轴向置于孔内壁的两端处。凸出结构3包括两个斜面4，斜面可以包括倾斜的平面和倾斜的曲面，还包括可由斜面衍生的其它形状的面，两个斜面4连接；
通过定位孔2内的凸出结构3的斜面4与孔壁结合固定导销7，每个定位孔2能够固定不同方向的两种导销7，定位孔2的内壁可在任何位置沿不同径向延伸设置凸出结构3，使导向套和导销7具有多种组合，且让每个导销7能适应两种方向的导向套，即适应两种方向的单板，实现槽位共享，减少专用槽位，例如：导向套包括第一导向套61和第二导向套62，导销包括第一导销71、第二导销72和第三导销73，如图4a和图4b所示，第一导向套61凸出结构3的设置方向，可以插接不同方向的第一导销71和第二导销72，如图5a和图5b所示,第二导向套62凸出结构3的设置方向，可以插接不同方向的第二导销72和第三导销73。当槽位设置的是第二导销时72，可以插接第一导向套61和第二导向套62，如果背板的槽位上导销的方向是固定的，交换单板上设置第一导向套61，业务单板设置第二导向套62，所述背板槽位上既可以插接交换单板，也可以插接业务单板，增强了单板的适配能力，提高了系统配置的灵活性和易用性，使系统的配置能力提高，且改变了传统同一单板更换导向套的方式，降低了维护成本。还可以通过导向套的凸出结构的方向与导销的配合具有防误插的功能，
在一个实施例中，所述两个斜面4的夹角为105-135度。
两个斜面4连接，两个斜面的夹角为105度-135度，使导销7插接于导向套时更紧密，当两个斜面连接处为一直线时，两个斜面的夹角为相交的夹角，当两个斜面通过弧面或者平面连接时，两个斜面的夹角为斜面延伸后相交的夹角。例如，当夹角为120度时，导销7 通过定位孔2内的其中一斜面4固定，则导销7与另一斜面4的夹角为120度，当导销7通过另一斜面4固定时，则导销7与其中一斜面4的夹角为120度，当夹角为130度时，导销7通过定位孔2内的其中一斜面4固定，则导销7与另一斜面4的夹角为130度，当导销7通过另一斜面4固定时，则导销7与其中一斜面4的夹角为130度，本领域的技术人员应该可以理解，这里只是用于举例说明，不应理解为对本公开的限制。夹角大小使导销7插接于导向套时留下的空隙较小，与内壁的结合更紧密。
在一个实施例中，所述两个斜面4连接处为一直线，且所述凸出结构3截面为三角形状，所述两个斜面4的宽度相同，或者两个斜面4的宽度不相同。在本公开的实施例中两个斜面4连接可形成一直线，凸出结构3的截面形状为三角形状。两个斜面4宽度相同，凸出结构3的截面形状为等腰三角形或者等边三角形，两个斜面4的宽度不相同时，凸出结构3的截面形状为不等边三角形。
在一个实施例中，所述两个斜面4通过弧面连接，如图6所示。所述两个斜面4的宽度相同，或者所述两个斜面4的宽度不相同。
在本公开的实施例中两个斜面4通过一个弧面连接。且两个斜面4的宽度可设置成相同，或者两个斜面4的宽度可设置成不同。
在一个实施例中，所述两个斜面4通过平面连接，如图7所示。所述两个斜面4的宽度相同，或者所述两个斜面4的宽度不相同。
在本公开的实施例中两个斜面4可通过一个平面连接。且两个斜面4的宽度可设置成相同，或者两个斜面4的宽度可设置成不同。
在一个实施例中，所述定位孔2为螺纹孔，所述两个斜面4上设置螺纹结构。
实施例中定位孔2为螺纹孔，凸出结构3的两个斜面4上设置螺纹结构，导销7可以为螺钉，配合将单板和背板插接在一块。
在一个实施例中，所述定位孔2为光孔，所述两个斜面4为光面。
实施例中定位孔2为光孔，凸出结构3的两个斜面4设置为光面，导销7可以为铆钉，配合将单板和背板插接在一块。
在一个实施例中，所述本体1的侧部设置有与单板9相接的连接结构8。
所述本体1的侧部设置连接结构8，通过连接结构8与单板9相接。
本公开还提出一种具有导向套的单板装置，该单板装置包括单板9和单板导向套6，如图8所示，该导向套6的结构参照上述实施例，由于本单板装置采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，
所述导向套通过连接结构8与单板相连。
应当说明的是，本公开的各个实施例的技术方案可以相互结合，但是必须是以本领域的技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当人认为这种技术方案的结合不存在，也不在本公开要求的保护范围之内。
本公开技术方案在具有防误插功能的同时，增强了单板的适配能力，提高了系统配置的灵活性和易用性，使系统的配置能力提高，且降低了维护成本。
通过上述技术方案，本公开单板导向套插接导销于定位孔时，定位孔一端的倾斜台阶可起初导向的作用，导向套能够插接两种不同方向的导销，不仅具有防误插功能，还增强了单板的适配能力，提高了系统配置的灵活性和易用性，使系统的配置能力提高，且改变了传统同一单板更换导向套的方式，降低了维护成本。
以上所述仅为本公开的优选实施例，并非因此限制本公开的专利范围，凡是利用本公开说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本公开的专利保护范围内。
