Description
Technical Field
[0001] This utility model relates to the technical field of optical fiber communication accessories, and more specifically, to an optoelectronic composite cable splice box. Background Technology
[0002] Optical fiber composite cable is a transmission line that combines optical fiber and conductor into one. Compared with traditional optical fiber, optical fiber composite cable integrates light and electricity, which can solve the problems of broadband access, equipment power supply and signal transmission, without being affected by the site. For example, when the optical modem is connected to the traditional optical fiber, it is also necessary to ensure that there is a socket for power supply, which restricts its installation location and must be installed in a place with a socket.
[0003] Because the length of the fiber optic composite cable may be limited during installation, splicing is required. However, when splicing is needed, the current fiber optic composite cable is first cut, and the two conductors and optical fiber are connected separately. The optical fiber is fused with a heat fusion tube, while the two conductors are simply wrapped with tape. After each unit is tied up, another layer of tape is wrapped around all three. This splicing method is too cumbersome, and the exposed tape is prone to falling off after a long period of exposure, increasing safety risks.
[0004] Therefore, based on the above problems, it is necessary to propose a junction box for optical-electric composite cables. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0036] It should be noted that the fiber optic connection is achieved by thermal fusion. The current operation involves placing two optical fibers into a thermal fusion tube and connecting them by heating them at high temperature.
[0037] Example 1:
[0038] This application provides an optoelectronic composite cable splice box, including a hollow box body, and at least one set of optoelectronic connection units are arranged inside the box body; one set of optoelectronic connection units includes an optical fiber positioning part and two conductive body docking parts, the optical fiber positioning part is used to fix the heat fusion tube that accommodates the optical fiber, and the conductive body docking parts are used to connect the positive and negative conductors; both ends of the optical fiber and both ends of the positive and negative conductors pass through the wall of the box body.
[0039] More specifically, such as Figure 1 As shown, the hollow box includes an upper box 1 and a lower box 2 with open connections, as well as a fixing structure for fixing the upper box 1 and the lower box 2 into one unit; the upper box 1 and the lower box 2 are respectively provided with an inlet 6 and an outlet 7 on their walls; the connected optical fiber and the two ends of the positive and negative conductors are removed through the inlet 6 and the outlet 7 respectively.
[0040] In the above embodiment, the connected optical fiber and heat fusion tube, as well as the two poles of the conductor, are all located inside the upper box 1 and the lower box 2 as a whole. Inside the upper box 1 and the lower box 2 as a whole, there is an optical fiber positioning part for fixing the heat fusion tube, and two sets of conductor docking parts. The positions of the optical fiber positioning part and the conductor docking parts can be arbitrarily configured, but it is ensured that the direction of the line in and out is set along the direction from the line inlet 6 to the line outlet 7. The positional order of the optical fiber positioning part and the conductor docking parts can be that the optical fiber positioning part is in the middle of the two sets of conductor docking parts, or on both sides.
[0041] Based on the above embodiments, such as Figure 1 and Figure 2 As shown, the inlet 6 and outlet 7 are located on opposite walls of the upper box 1 and lower box 2, respectively. The two ends of the fiber positioning part are directly opposite the inlet 6 and outlet 7. The two conductive docking parts are located on both sides of the fiber positioning part. By restricting the position of the fiber positioning part and the conductive docking part, the bending of the fiber optic hot melt tube and the conductive part inside the box can be effectively avoided.
[0042] More specifically, such as Figure 1 and Figure 2 As shown, the fiber positioning unit includes two parallel heat fusion tube baffles 3 fixed to the bottom of the lower box 2. The heat fusion tube is installed between the two heat fusion tube baffles 3. Since the heat fusion tube is a long tube, the two heat fusion tube baffles 3 just limit and fix the heat fusion tube on both sides.
[0043] More specifically, such as Figure 1 and Figure 2 As shown, the inner walls of the two hot melt tube baffles 3 are provided with multiple protrusions at equal intervals along the installation direction of the hot melt tube. The purpose of this design is to increase the friction between the hot melt tube baffles 3 and the hot melt tube and prevent the hot melt tube from shaking. The protrusions here can be the strip-shaped protrusions shown in the figure or the dot-shaped protrusions. The material can be rubber or other particles that can increase friction.
[0044] Based on the above embodiments, such as Figure 5 As shown, the conductive body docking part includes a conductive body connecting plate 4 and a plate support 5. The plate support 5 and the bottom of the inner wall of the lower box 2 are integrally formed. The conductive body connecting plate 4 is inserted into the top of the plate support 5. The conductive body connecting plate 4 adopts an existing conductive body connecting component, which has a terminal block and a clip inside. At the same time, the top two sides are raised. During installation, the plate is opened by pressing down, and the conductive bodies are placed in it. After releasing, the elasticity of the material itself is used to reset and press the plate to quickly fix the conductive bodies. Of course, there are many alternatives to the structure of the conductive body connecting plate 4 on the market, which will not be described in detail in this application.
[0045] Based on the above embodiments, such as Figure 1As shown, the fixing structure includes bolt mounting slots 8 at the four corners of the upper box 1 and internal threaded holes 9 at the four corners of the lower box 2, corresponding to the positions of the bolt mounting slots 8; the bolts fix the upper box 1 and the lower box 2 in sequence through the bolt mounting slots 8 and the internal threaded holes 9. In this embodiment, the boxes are fixed by bolts at the four corners of the box body.
[0046] Based on the above embodiment, the fixing structure includes a locking plate 10 and a limiting port 11. Multiple sets of locking plates 10 and limiting ports 11 are correspondingly provided. Multiple locking plates 10 are disposed on the upper box 1 or the lower box 2, and multiple limiting ports 11 are disposed on the corresponding other half of the box. The upper box 1 and the lower box 2 are fixed together by multiple locking plates 10 and multiple limiting ports 11. This embodiment fixes the box body through a snap-fit mechanism. Figure 1 As shown, both sides of the bottom of the upper box 1 are provided with downward extending card plates 10, while the two end walls of the lower box 2 are provided with limiting ports 11 that cooperate with the bottom buckles of the card plates 10. By pressing down the upper box 1, the bottom buckles of the card plates 10 enter the limiting ports 11 to achieve quick fixation.
[0047] Of course, in the above embodiments, the card plate 10 and the limiting port 11 can also be respectively set on the lower box 2 and the upper box 1, or cross-set on the lower box 2 and the upper box 1. The change of position does not affect the effect of this embodiment.
[0048] Based on the above embodiments, such as Figure 1 and Figure 4 As shown, the inlet 6 and outlet 7 are respectively located at both ends of the upper box 1 or both ends of the lower box 2; the other half of the box is provided with a third vertical cable plate 12 that is movably inserted into the inlet 6 and outlet 7 at the positions corresponding to the inlet 6 and outlet 7. When the upper box 1 is pressed down, the third vertical cable plates 12 on both sides enter the inlet 6 and outlet 7. The purpose of this embodiment is to avoid the inlet 6 and outlet 7 being too large after the box is installed, so as to achieve a certain cable bundling effect.
[0049] Of course, in the above embodiments, the third vertical plate 12 can be set on the lower box 2, and the inlet 6 and outlet 7 can be set at both ends of the upper box 1. The change of position does not affect the effect of this embodiment.
[0050] Based on the above embodiments, such as Figure 6 As shown, the third vertical cable plate 12 is detachably connected to the other half of the box. The third vertical cable plate 12 is provided with multiple cable bundling holes 17. In this embodiment, the third vertical cable plate 12 completely closes the inlet port 6 or outlet port 7, while the optical fiber and conductor pass through the box through the cable bundling holes 17, which can better fix the cable bundle and facilitate waterproofing at the interface.
[0051] Based on the above embodiments, such as Figure 2 and Figure 3As shown, the upper box 1 has second vertical wire plates 16 at both ends inside; the lower box 2 has first wire-binding plates 13 at both ends inside, corresponding vertically to the second vertical wire plates 16. The first wire-binding plates 13 and the second vertical wire plates 16 correspond to the positions of the wire inlet 6 and the wire outlet 7. The function of the second vertical wire plates 16 and the first wire-binding plates 13 is to bind the wires, preventing the wiring at the wire inlet 6 and the wire outlet 7 from being too loose and causing accumulation and tangling. Figure 2 and Figure 3 The wire harness structure can be made of parallel plates, or the wires can be fixed by passing through holes. For example, holes can be made in the vertical wire plate and the vertical wire plate can be set to face the inlet 6 and outlet 7 to achieve the same effect. However, no matter what kind of wire harness structure is used, it should fall within the protection scope of this application.
[0052] Based on the above embodiments, such as Figure 2 and Figure 3 As shown, a connecting groove 14 is provided around the inner wall of the opening of either the upper box 1 or the lower box 2, and a connecting plate 15 that engages with the connecting groove 14 is provided around the opening of the connecting plate 15 of the other half box. The connecting groove 14 and the connecting plate 15 facilitate the quick docking of the upper box 1 and the lower box 2, and effectively fix the docking seam. At the same time, this setting also facilitates waterproofing treatment at the interface, such as adding a waterproof gasket.
[0053] Example 2:
[0054] Please see Figure 6-8 Based on Example 1, this embodiment adds multiple sets of optoelectronic connection units inside the box, making it convenient for use in large-scale scenarios requiring multiple connections and increasing the application range.
[0055] The optoelectronic composite cable splice box provided in this application can be applied to various construction scenarios, enabling rapid wiring while effectively protecting the wiring location, and has good application prospects.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
