Accordingly, the structure and assembly process of the second back box 300 may be similar to those of the first back box 200, and of course, the structures of the first back box 200 and the second back box 300 may be identical. In addition, the two first back boxes 200 may be connected together by the back box connecting means 100.
Or, the first bottom case 200 may include a body 210 and a sleeve, one end of the sleeve is connected to the body 210, and the other end of the sleeve has a through hole, so that the sleeve is inserted into and matched with the first connection pipe 120, and the purpose of connecting the first bottom case 200 and the bottom case connection device 100 may also be achieved, thereby connecting the first bottom case 200 and the second bottom case 300 into a whole.

In addition, in order to facilitate the wiring work between the first bottom case 200 and the second bottom case 300, through holes or sleeves may be provided around each of the first bottom case 200 and the second bottom case 300, so that the cables can be inserted between the first bottom case 200 and the second bottom case 300. Moreover, any side of the first bottom case 200 and/or the second bottom case 300 may be provided with two through holes or two sleeves, which may further improve the convenience of the first bottom case 200. In the case where two through-holes are provided in one side edge of the first bottom case 200, the two through-holes may be the same or different in size and/or shape; accordingly, in the case where two sleeves are provided on the same side of the first chassis 200, the two sleeves may be identical or different in size and/or shape.
As shown in fig. 1 and 2, the bottom case connection device 100 includes a base 110, and a first connection pipe 120 and a second connection pipe 130 located at both sides of the base 110, where both ends of the first connection pipe 120 facing away from the base 110 and the second connection pipe 130 facing away from the base 110 are insertion parts, and in the process of connecting the first bottom case 200 and the second bottom case 300, the two insertion parts are respectively connected with the first bottom case 200 and the second bottom case 300. Also, the spaces at both sides of the base 110 may be communicated through the first and second connection pipes 120 and 130, so that the cables may be extended from the first back box 200 into the second back box 300 through the back box connection device 100 when the back box connection device 100 is connected to the first back box 200 and the second back box 300.

Alternatively, the cross section of the first connection pipe 120 and/or the second connection pipe 130 may be polygonal, for example, the cross section of the first connection pipe 120 may be triangular, rectangular, pentagonal, or other polygonal shapes. In order to increase the amount of cables that can be accommodated in the first connecting tube 120 (and the second connecting tube 130) having a similar size, it is preferable that the cross-sections of the first connecting tube 120 and the second connecting tube 130 are each a polygon having a number of sides greater than or equal to 4, in consideration of the fact that the cables need to be inserted through the first connecting tube 120 and the second connecting tube 130 during the use of the back box connecting device 100.
Alternatively, the first connection pipe 120 and the second connection pipe 130 may be disposed to face each other, so that the first connection pipe 120 and the second connection pipe 130 may be connected to the same-positioned components (or structures) on the first bottom case 200 and the second bottom case 300, respectively; alternatively, the first connection pipe 120 and the second connection pipe 130 may be disposed in a staggered manner, that is, they are inclined to each other, and in this case, the position of the structure connecting the first connection pipe 120 and the first bottom case 200 is different from the position of the structure connecting the second connection pipe 130 and the second bottom case 300, and those skilled in the art can select them according to actual situations.
Optionally, at least two first connecting pipes 120 and at least two second connecting pipes 130 may be provided, and the two first connecting pipes 120 are located on the same side of the base 110, or the two first connecting pipes 120 are located on two sides of the base 110 respectively, and the ends of the first connecting pipes 120 and the ends of the second connecting pipes 130 that are away from the base 110 are plug ends, so that it may be ensured that either side of the base 110 has at least two plug ends, and each plug end is connected with a component (or structure) at a corresponding position on the first bottom case 200 and the second bottom case 300 respectively. It should be noted that the components of the first bottom case 200 and the second bottom case 300, which are engaged with the insertion end in an insertion manner, may be through holes and/or sleeves.
In order to further improve the firmness of the first and second cases 200 and 300 connected by the case connecting device 100, and considering that two through holes are generally formed in the side surface of the conventional case, it is preferable that two first connecting pipes 120 and two second connecting pipes 130 are provided, and two first connecting pipes 120 and two second connecting pipes 130 are respectively located at both sides of the base 110.
In addition, because the embodiment of the present invention discloses the first connecting pipe 120 and the second connecting pipe 130 in the bottom case connecting device 100 are both tubular structures, therefore, in the process of connecting the first bottom case 200 and the second bottom case 300 by using the bottom case connecting device 100, the sizes of the insertion ends of the first connecting pipe 120 extending into the first bottom case 200 are different, and/or the sizes of the insertion ends of the second connecting pipe 130 extending into the second bottom case 300 are different, so that when the first bottom case 200 and the second bottom case 300 form a connection relationship, the distance between the first bottom case 200 and the second bottom case 300 can be flexibly adjusted according to actual requirements, thereby adapting to switches of different sizes, and ensuring that the connection relationship between the switch and the first bottom case 200 and the second bottom case 300 is reliable. Specifically, the dimension of the insertion end along the axial direction thereof may be determined according to practical situations, and is not limited herein.
In order to more easily distinguish the first and second connection pipes 120 and 130 in some cases to connect with the first and second bottom cases 200 and 300 having different structures or sizes, alternatively, the first and second connection pipes 120 and 130 may each have a polygonal cross-section, and the diameter of the inscribed circle of the first connection pipe 120 may be made larger than that of the inscribed circle of the second connection pipe 130. Specifically, the respective sizes of the first connection pipe 120 and the second connection pipe 130 may be determined according to practical situations, and are not limited herein.
As described above, the first connection pipe 120 and the second connection pipe 130 may be provided in two, and the two first connection pipes 120 are provided corresponding to the two second connection pipes 130, which may further improve the fastening effect generated when the first back box 200 and the second back box 300 are connected using the back box connecting device 100.
As described above, in the case where the shapes of the cross sections of both the first and second connection pipes 120 and 130 are the same, the sizes of both the first and second connection pipes 120 and 130 may be different. In one case, in the case where the first connection pipe 120 and the second connection pipe 130 have polygonal cross sections, the diameters of inscribed circles of the first connection pipe 120 and the second connection pipe 130 may be different from each other, or the diameters of external sources of the first connection pipe 120 and the second connection pipe 130 may be different from each other.
Specifically, the first connection pipe 120 and the second connection pipe 130 may be respectively fitted to through holes having different sizes by making the maximum size of the first connection pipe 120 larger than the maximum size of the second connection pipe 130 in a direction perpendicular to the axis of the first connection pipe 120. For example, the cross-sectional shapes of the first connection pipe 120 and the second connection pipe 130 may be regular octagons, and the outer walls of the first connection pipe and the second connection pipe may have different sizes, so that the first connection pipe and the second connection pipe may be respectively inserted into through holes having different sizes. It should be noted that the back box connecting device 100 may be designed according to the structure and size of a conventional back box, or the structure and size of the first back box 200 and the second back box 300 may be made to correspond to the structure and size of the back box connecting device 100.
In addition, as described above, in addition to forming the through hole for inserting and matching with the first connection pipe 120 and/or the second connection pipe 130 on the side wall of the first bottom case 200, a sleeve may be provided on the first bottom case 200, so that the purpose of inserting and matching the first bottom case 200 and the bottom case connection device 100 is achieved by the sleeve. It should be noted that the second bottom case 300 can also be matched with the bottom case connection device 100 by means of a sleeve, and the first bottom case 200 is only described as an example in the present disclosure in consideration of text indirection.
In the case that the first bottom case 200 is provided with the sleeve, there are various insertion manners between the first connection pipe 120 and the second connection pipe 130 and the sleeve, for example, by designing the size and shape of the first connection pipe 120, the second connection pipe 130 and the sleeve, the first connection pipe 120 and the second connection pipe 130 can be both inserted outside the sleeve, the first connection pipe 120 and the second connection pipe 130 can be both inserted inside the sleeve, one of the first connection pipe 120 and the second connection pipe 130 can be inserted outside the sleeve, and the other can be inserted inside the sleeve, which is not limited herein.
As described above, the present invention also discloses a socket assembly, which includes the first bottom case 200, the second bottom case 300 and the bottom case connecting device 100, in the case that the cross-sections of the first connecting pipe 120 and the second connecting pipe 130 are both polygonal, in order to make the connection relationship between the first bottom case 200 and the second bottom case 300 more compact, preferably, the first bottom case 200 may be provided with a polygonal through hole or a polygonal sleeve pipe, and the through hole and the sleeve pipe may be respectively identical to the cross-sections of the corresponding first connecting pipe 120 and the second connecting pipe 130, and the size is corresponding, which may ensure that the overall structural stability of the socket assembly is higher. Likewise, the same applies to the second bottom case 300.
In order to further improve the convenience of the bottom case connecting device 100 disclosed in the embodiment of the present invention, preferably, the cross sections of the first connecting tube 120 and the second connecting tube 130 can be polygons with even number of sides, in this case, the worker can connect the first bottom case 200 and the second bottom case 300 by using the bottom case connecting device 100 without determining the orientation and direction of the bottom case connecting device 100, and only the first connecting tube 120 is directly connected to the through hole of the first bottom case 200, and the second connecting tube 130 is connected to the through hole of the second bottom case 300. Especially, under the condition that the through holes of the first bottom case 200 and the second bottom case 300 are also polygonal, in the process of assembling the first connecting pipe 120 with the through hole of the first bottom case 200, the first connecting pipe 120 with the polygonal structure of the even number sides only needs to be correspondingly inserted into the first connecting pipe 120 and the second connecting pipe 130 through different through holes, and the relative position of the polygonal structure does not need to be judged, which is beneficial to further improving the convenience of the bottom case connecting device 100. Specifically, both the first connection pipe 120 and the second connection pipe 130 may have a polygonal cross-section, for example, a rectangular, hexagonal, octagonal, or the like.
Further, in order to prevent the first connection pipe 120 from coming off from the first bottom case 200, preferably, as shown in fig. 2, an anti-disengagement rib 140 may be disposed on the first connection pipe 120, so that after the first connection pipe is inserted into and matched with the first bottom case 200, with the help of the anti-disengagement rib 140, the anti-disengagement reliability between the first connection pipe 120 and the first bottom case 200 may be further improved, and a reliable connection relationship between the first bottom case 200 and the bottom case connection device 100 is ensured. Similarly, the second connection pipe 130 may also be provided with an anti-dropping rib 140 to ensure that the second connection pipe 140 and the first bottom case 200 and/or the second bottom case 300 have higher connection reliability.
Specifically, the shape and size of the anti-separation rib 140 can be determined according to actual conditions, and in order to facilitate the assembly and disassembly of the first bottom case 200 and the bottom case connecting device 100, preferably, both ends of the anti-separation rib 140 can be arc-shaped guide ends, so that the first connecting pipe 120 can be conveniently inserted into the first bottom case 200 on one hand, and the first connecting pipe 120 can be conveniently detached from the first bottom case 200 on the other hand, thereby further improving the convenience in use of the whole bottom case connecting device 100.
As described above, in the socket assembly of the present invention, the first connecting pipe 120 and the second connecting pipe 130 are connected to the sleeve in various ways. The disengagement-prevention rib 140 may be provided on the inner wall of the first connection pipe 120 if the first connection pipe 120 is sleeved outside the sleeve, and the disengagement-prevention rib 140 may be provided on the outer wall of the first connection pipe 120 if the sleeve is sleeved outside the first connection pipe 120.
In order to further improve the connection reliability between the first connection pipe 120 and the first bottom case 200, the anti-slip ribs 140 may be provided in plurality, the shapes and the sizes of the plurality of anti-slip ribs 140 may be the same, and the plurality of anti-slip ribs 140 may be arranged in the circumferential direction of the first connection pipe 120. The number of the anti-slip ribs 140 may be three, four, five, or the like, and the plurality of anti-slip ribs 140 may be uniformly and alternately disposed.
In addition, in the socket assembly disclosed in the embodiment of the present invention, under the condition that the first bottom case 200 includes the body 210 and the sleeve, when the first connecting pipe is provided with the anti-separation rib 140, in order to further improve the connection stability between the first bottom case 200 and the bottom case connecting device 100, as shown in fig. 6, the anti-separation protrusion 240 can be correspondingly designed on the sleeve, and the anti-separation rib 140 and the anti-separation protrusion 240 are mutually matched, so that the axial limit matching relationship between the first bottom case 200 and the bottom case connecting device 100 on the first connecting pipe 120 is further improved. Similarly, in the case that the second connecting pipe 130 is matched with the second bottom case 300 and the anti-drop rib 140 is disposed on the second connecting pipe 130, the anti-drop protrusion 240 may also be disposed on the second bottom case 300 to ensure that the connection reliability between the bottom case connecting device 100 and the second bottom case 300 is relatively high.
Specifically, the shape and size of the anti-separation protrusion 240 may be correspondingly determined according to the shape and size of the anti-separation protrusion 140, so that under the condition that the anti-separation protrusion 140 and the anti-separation protrusion 240 are mutually matched, it is ensured that the connection reliability between the first connection pipe 120 (or the second connection pipe 130) and the sleeve is improved, and a large obstruction is not substantially generated to the plugging process between the first connection pipe 120 (or the second connection pipe 130) and the sleeve. In order to further reduce the blocking effect generated in the insertion process due to the existence of the anti-separation ribs 140 and the anti-separation protrusions 240, the ends of the anti-separation protrusions 240 and the anti-separation ribs 140 can be set to be arc-shaped guide structures, so that the convenience in the process of assembling and disassembling the first connecting pipe 120 (or the second connecting pipe 130) and the sleeve pipe is improved.
As described above, in the case where the first connection pipe 120 and the second connection pipe 130 are different in shape and/or size, etc., there are various ways of coupling the first connection pipe 120 and the second connection pipe 130 to the sleeve. Also, in order to improve the connection reliability between the back box connecting device 100 and the first back box 200, one side of the body 210 in the first back box 200 may be provided with a plurality of sleeves to be connected with the back box connecting device 100 through the plurality of sleeves.
Optionally, different sleeves of the plurality of sleeves on one side of the body 210 are inserted into different first connecting pipes 120 in different manners, for example, at least one first connecting pipe 120 may be inserted into a sleeve, and at least one sleeve may be sleeved outside the first connecting pipe 120.
Further, under the condition that the first connection tube 120 and the second connection tube 130 are simultaneously disposed on the same side of the base 110, as shown in fig. 5 and 6, the plurality of sleeves located on the same side of the body 210 may include the first sleeve 220 and the second sleeve 230, in the process of assembling the socket assembly, the first connection tube 120 may be sleeved outside the first sleeve 220, and the second sleeve 230 may be sleeved outside the second connection tube 130, and this sleeving manner may generate a certain limiting effect on the relative position relationship among the chassis connection device 100, the first chassis 200, and the second chassis 300, and further improve the structural stability of the whole socket assembly.
Further, as shown in fig. 5 and 6, a portion of the base 110 may be configured to generate a blocking effect on the inner cavity of the first connection tube 120 at the end of the first connection tube 120 along the axial direction of the first connection tube 120. In this case, after the first sleeve 220 is inserted into the first connecting tube 120, due to the plugging condition of the end of the first connecting tube 120 connected to the base body 110, the portion of the base body 110 located in the first connecting tube 120 can provide a limiting effect for the first sleeve 220, and prevent the first sleeve 220 from moving further into the first connecting tube 120.
Meanwhile, because the second sleeve 230 is sleeved outside the second connecting pipe 130, and the second connecting pipe 130 is connected with the base 110, the second sleeve 230 can be prevented from continuously moving to the deep part of the second connecting pipe 130 under the action of the base 110; in addition, as described above, it is also possible to further ensure that there is substantially no axial play between the first and second bottom cases 200 and 300 connected by the bottom case connecting device 100 by forming the escape prevention protrusions 240 on the first and second connecting pipes 120 and 130 and forming the escape prevention protrusions 240 on the first and second sleeves 220 and 230.
Further, in the case that the first connection pipe 120 and the second connection pipe 130 are both provided with two sleeves, and the first bottom case 200 is provided with two sleeves on the same side, the two first connection pipes 120 and the two second connection pipes 130 are respectively sleeved with the respective two sleeves of the first bottom case 200 and the second bottom case 300, so that the relative rotation between the first bottom case 200 and the second bottom case 300 can be substantially prevented. Further, even when the first and second cases 200 and 300 are subjected to a force, the first and second cases 200 and 300 are not substantially inclined with respect to each other. In the case that the three components of the first connecting pipe 120, the second connecting pipe 130 and the sleeve are polygonal structures, it is possible to further prevent the first bottom case 200 and the second bottom case 300 from being relatively rotated or relatively inclined when a force is applied.

Two sleeves are arranged on two opposite sides of the body 210, the two sleeves located on the same side of the body 210 are a first sleeve 220 and a second sleeve 230 respectively, the first connecting pipe 120, the second connecting pipe 130, the first sleeve 220 and the second sleeve 230 are all tubular structures, and the cross sections of the first connecting pipe, the second connecting pipe and the first sleeve are polygons with even side lengths. The first sleeve 220 and the second sleeve 230 have different sizes, wherein the first sleeve 220 is inserted into the first connection pipe 120, and the second sleeve 230 is sleeved outside the second connection pipe 130. The inner wall of the first connecting tube 120 is sized to fit the outer wall of the first sleeve 220 and the outer wall of the second connecting tube 130 is sized to fit the inner wall of the second sleeve 230. The inner wall of the first connecting pipe 120 is provided with an anti-slip convex rib 140, the outer wall of the first sleeve 220 is provided with an anti-slip protrusion 240, the outer wall of the second connecting pipe 130 is provided with an anti-slip convex rib 140, and the inner wall of the second sleeve 230 is provided with an anti-slip protrusion 240. In addition, the base body 110 blocks a portion of the inner cavity of the first connecting tube 120 to limit the position of the cannula which is inserted into the first connecting tube 120.
