背景技术Background technique
光纤接线盒的光缆进出端口一般采用橡胶块进行密封。在现有技术中，该橡胶块一般包括两个能够相互压配在一起的半体块，光缆放置在一对半体块之间，当两个半体块压配在一起时，光缆就被密封地包裹在一对半体块之间的密封槽中。The fiber optic cable inlet and outlet ports of the fiber optic junction box are generally sealed with rubber blocks. In the prior art, the rubber block generally includes two half blocks that can be press-fitted together, and the optical cable is placed between the pair of half blocks. When the two half blocks are press-fit together, the optical cable is Hermetically encased in a sealed groove between a pair of half-blocks.
但是，当在现场安装光纤接线盒时，需要先将一对半体块压配在一起，由于受到现场安装空间的限制，压配一对半体块比较困难，有时甚至需要借助于一些专用工具才能实现。在将光缆压配和密封在一对半体块之间后，还需要盖上壳体盖，以便密封壳体的端口。However, when the optical fiber junction box is installed on site, it is necessary to press fit a pair of half blocks together. Due to the limitation of the installation space on site, it is difficult to press fit a pair of half blocks, and sometimes even need to use some special tools in order to achieve. After the cable is press-fitted and sealed between the pair of half-blocks, the housing cover is also required to seal the housing ports.

具体实施方式Detailed ways
下面详细描述本发明的实例性的实施例，实施例的示例在附图中示出，其中相同或相似的标号表示相同或相似的元件。下面参考附图描述的实施例是示例性的，旨在解释本发明，而不能解释为对本发明的限制。Exemplary embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals designate the same or similar elements. The embodiments described below with reference to the figures are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.
【第一实施例】【The first embodiment】
图1显示根据本发明的第一优选实施例的光纤接线盒的立体示意图；图2显示图1所示的光纤接线盒的装配过程。FIG. 1 shows a schematic perspective view of an optical fiber splice box according to a first preferred embodiment of the present invention; FIG. 2 shows the assembly process of the optical fiber splice box shown in FIG. 1 .
如图1所示，光纤接线盒主要包括壳体和容纳在壳体中的接线单元(未图示，如跳线管理单元、熔纤管理单元、盘纤管理单元等)。As shown in FIG. 1 , the optical fiber junction box mainly includes a housing and a wiring unit (not shown, such as a jumper management unit, a spliced fiber management unit, and a fiber disk management unit, etc.) accommodated in the housing.
在图1所示的实施例中，壳体包括上盖1和底座2，上盖1和底座2能够可拆卸地连接在一起。In the embodiment shown in FIG. 1 , the housing includes an upper cover 1 and a base 2 , and the upper cover 1 and the base 2 can be detachably connected together.
如图1所示，壳体具有让光缆4穿过的开口(光缆进出端口)，在壳体的光缆进出端口处设置有弹性密封块3，用于密封壳体的光缆进出端口。As shown in Figure 1, the housing has an opening (cable inlet and outlet port) through which the optical cable 4 passes, and an elastic sealing block 3 is arranged at the optical cable inlet and outlet port of the housing to seal the optical cable inlet and outlet port of the housing.
为了便于说明，如图1所示，在本说明书中，光纤接线盒的长度方向用Y表示，宽度方向用X表示，高度方向或竖直方向用Z表示。如图1所示，长度方向Y实际上就是光缆4的轴向方向，而宽度方向X和高度方向Z为垂直于光缆4的轴向方向的径向方向。For ease of description, as shown in FIG. 1 , in this specification, the length direction of the optical fiber junction box is represented by Y, the width direction is represented by X, and the height direction or vertical direction is represented by Z. As shown in FIG. 1 , the length direction Y is actually the axial direction of the optical cable 4 , while the width direction X and the height direction Z are radial directions perpendicular to the axial direction of the optical cable 4 .
在图1和图2所示的优选实施例中，弹性密封块3是一个整体件。在弹性密封块3的上边缘形成有多个间隔开的容纳凹槽7，光缆4穿过并保持在该容纳凹槽7中。In the preferred embodiment shown in Figures 1 and 2, the elastic sealing block 3 is a single piece. A plurality of spaced accommodating grooves 7 are formed on the upper edge of the elastic sealing block 3 , and the optical cable 4 passes through and is held in the accommodating grooves 7 .
请继续参见图1和图2所示的优选实施例，容纳凹槽7是从弹性密封块3的边缘向内延伸的细长沟槽。Please continue to refer to the preferred embodiment shown in FIG. 1 and FIG. 2 , the accommodating groove 7 is an elongated groove extending inward from the edge of the elastic sealing block 3 .
如图1和图2所示，在弹性密封块3的下边缘没有形成容纳光缆4的容纳凹槽7，因此，弹性密封块3的下边缘可以直接与底座2连接在一起，从而使得弹性密封块3与底座2形成一体。这样做的优点是能够省去将弹性密封块3定位和放置在底座2中的步骤。As shown in Fig. 1 and Fig. 2, the receiving groove 7 for accommodating the optical cable 4 is not formed on the lower edge of the elastic sealing block 3, therefore, the lower edge of the elastic sealing block 3 can be directly connected with the base 2, so that the elastic sealing The block 3 is integral with the base 2 . The advantage of doing this is that the step of positioning and placing the elastic sealing block 3 in the base 2 can be omitted.
但是，需要说明的是，弹性密封块3的下边缘也可以形成与上边缘相似的容纳凹槽，而不与底座2形成一体，这样，虽然增加了将弹性密封块3定位和放置在底座2中的步骤，但是能够增加容纳和密封光缆的数量。However, it should be noted that the lower edge of the elastic sealing block 3 can also form an accommodating groove similar to the upper edge, instead of being integrated with the base 2. In this way, although the elastic sealing block 3 is positioned and placed on the base 2 steps in, but able to increase the number of cables accommodated and sealed.
下面根据图2来具体说明本发明的第一实施例的光纤接线盒的装配过程。在图2所示的优选实施例中，先将光缆4保持在容纳凹槽7中。然后直接关闭上盖1向下挤压弹性密封块3使容纳凹槽7闭合，从而实现光缆4的密封。The assembly process of the optical fiber junction box according to the first embodiment of the present invention will be described in detail below according to FIG. 2 . In the preferred embodiment shown in FIG. 2 , the optical cable 4 is first held in the receiving groove 7 . Then directly close the upper cover 1 and press down the elastic sealing block 3 to close the accommodating groove 7 , so as to realize the sealing of the optical cable 4 .
在现有技术中，是通过一对相互配合的弹性密封块的相互挤压来将光缆保持和密封在一对相互配合的弹性密封块之间。而在本发明中，是通过在弹性密封块3的上部和/或下部形成多个间隔开的容纳凹槽7，通过上盖1和/或底座2直接挤压该弹性密封块3的上部和/或下部，从而使得光缆4被密封地保持在弹性密封块3的容纳凹槽7中。与现有技术相比，本发明具有装配方便，效率高的优点。In the prior art, the optical cable is held and sealed between a pair of elastic sealing blocks that cooperate with each other by pressing the pair of elastic sealing blocks that cooperate with each other. However, in the present invention, a plurality of spaced accommodating grooves 7 are formed on the upper and/or lower parts of the elastic sealing block 3, and the upper and/or lower parts of the elastic sealing block 3 are directly pressed by the upper cover 1 and/or the base 2. /or the lower part, so that the optical cable 4 is hermetically held in the receiving groove 7 of the elastic sealing block 3 .

Specifically, as shown in FIG. 2 , the upper cover 1 includes an upper extruding portion 1a for extruding the upper portion of the elastic sealing block 3 , and the base 2 includes a lower extruding portion 2a for extruding the lower portion of the elastic sealing block 3 . In the preferred embodiment shown in FIG. 2, the upper extrusion part 1a and the lower extrusion part 2a are formed so that when the upper cover 1 and the base 2 are closed together, the height between the upper extrusion part 1a and the lower extrusion part 2a is The shortest vertical distance in the direction or vertical direction Z is less than the maximum height of the elastic sealing block 3 in the uncompressed front height direction Z, so that the upper extruding part 1a and the lower extruding part 2a can apply a vertical force to the elastic sealing block 3 together. Extrusion force, and then the vertical extrusion force is converted into a radial extrusion force exerted on the optical cable 4.
如图2所示，当上盖1逐渐关闭时，上挤压部1a和下挤压部2a沿光缆4的径向方向(即竖直方向Z)逐渐挤压弹性密封块3，从而实现对光缆4的密封。As shown in Figure 2, when the upper cover 1 is gradually closed, the upper pressing part 1a and the lower pressing part 2a gradually press the elastic sealing block 3 along the radial direction of the optical cable 4 (that is, the vertical direction Z), so as to achieve The sealing of the optical cable 4.
请注意，在本发明的各个实施例中，壳体必须具有一定的刚度，这样才能挤压弹性密封块。在本发明中，与弹性密封块3相比，壳体可以说是刚性的。Please note that in each embodiment of the present invention, the housing must have a certain rigidity, so that the elastic sealing block can be pressed. In the present invention, the housing can be said to be rigid compared to the elastic sealing block 3 .

如图5所示，在图示的优选实施例中，在关闭上盖1时，上盖1和底座2上下挤压弹性密封块，使得弹性密封块受压变形，从而密封地包裹住光缆4。具体地，如图5所示，上盖1包括挤压弹性密封块的上部的上挤压部1a，底座2包括挤压弹性密封块的下部的下挤压部2a。在图5所示的优选实施例中，上挤压部1a和下挤压部2a形成为当上盖1和底座2关闭在一起时上挤压部1a和下挤压部2a之间沿高度方向或竖直方向Z的最短的竖直距离小于整个弹性密封块3a、3b在未压缩前沿高度方向Z的最大高度，从而上挤压部1a与下挤压部2a能够一起对整个弹性密封块3a、3b施加竖直挤压力，然后该竖直挤压力转换成施加在光缆4上的径向挤压力。As shown in Figure 5, in the preferred embodiment shown in the figure, when the upper cover 1 is closed, the upper cover 1 and the base 2 press the elastic sealing block up and down, so that the elastic sealing block is deformed under pressure, thereby sealingly wrapping the optical cable 4 . Specifically, as shown in FIG. 5 , the upper cover 1 includes an upper extruded portion 1a for extruding the upper portion of the elastic sealing block, and the base 2 includes a lower extruding portion 2a for extruding the lower portion of the elastic sealing block. In the preferred embodiment shown in Fig. 5, the upper extrusion part 1a and the lower extrusion part 2a are formed so that when the upper cover 1 and the base 2 are closed together, the height between the upper extrusion part 1a and the lower extrusion part 2a is The shortest vertical distance in the direction or vertical direction Z is less than the maximum height of the entire elastic sealing block 3a, 3b in the uncompressed front height direction Z, so that the upper extruding part 1a and the lower extruding part 2a can together press the entire elastic sealing block 3a, 3b apply a vertical crushing force which is then converted into a radial crushing force on the optical cable 4 .
如图5所示，当上盖1逐渐关闭时，上挤压部1a和下挤压部2a沿光缆4的径向方向(即竖直方向Z)逐渐挤压第一和第二弹性密封块3a、3b，从而实现对光缆4的密封。As shown in Figure 5, when the upper cover 1 is gradually closed, the upper pressing part 1a and the lower pressing part 2a gradually press the first and second elastic sealing blocks along the radial direction of the optical cable 4 (that is, the vertical direction Z) 3a, 3b, so as to realize the sealing of the optical cable 4.
为了提高密封效果，在本发明的一个优选实施例中，弹性密封块采用凝胶块单元，因为凝胶较软易受压变形，而且凝胶密封效果好。但是，本发明不局限于此，弹性密封块也可以采用较软的橡胶、马蹄胶等其它合适的弹性密封材料制成。In order to improve the sealing effect, in a preferred embodiment of the present invention, the elastic sealing block adopts a gel block unit, because the gel is soft and easily deformed under pressure, and the gel sealing effect is good. However, the present invention is not limited thereto, and the elastic sealing block can also be made of other suitable elastic sealing materials such as softer rubber and horseshoe rubber.
下面根据图4来详细说明本发明的第二实施例的光纤接线盒的上盖的上挤压部1a的结构。The structure of the upper extruding portion 1a of the upper cover of the optical fiber junction box according to the second embodiment of the present invention will be described in detail below with reference to FIG. 4 .
