Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of optical-electrical composite cable, in particular to an optical-electrical composite cable splicing box. BACKGROUND

[0002] Optical-electrical composite cable, that is, integrating optical fiber and wire in the same sheath. The optical-electrical composite cable continues the advantages of high-speed optical fiber communication, and can also provide power supply for powered equipment for a distance of several meters to several hundred meters to solve the actual scene problem of powered equipment near power supply inconvenience.

[0003] With the large use of optical-electrical composite cable, the demand for optical-electrical composite cable maintenance and matching is increasing. For example, the demand for optical-electrical composite cable repair, optical-electrical composite cable extension and optical-electrical composite cable loading connector.

[0004] Therefore, there is an urgent need for a device that can conveniently splice two optical-electrical composite cables. INVENTION CONTENTS

[0005] The present disclosure provides an optical-electrical composite cable splicing box. The optical-electrical composite cable splicing box can realize the splicing of two optical-electrical composite cables, and does not need to strip the bare wire in the optical-electrical composite cable, and the splicing operation is simple and fast. The technical scheme of the optical-electrical composite cable splicing box is as follows.

[0006] The present disclosure provides an optical-electrical composite cable splicing box. The optical-electrical composite cable splicing box includes a base, two conductive pieces and a cover. The base includes a cable slot, and the cable slot includes a side opening and two end openings. The two end openings are used for two optical-electrical composite cables to pass through. The cable slot is used to accommodate a protective sleeve, and the protective sleeve is used to enclose the hot melt joint part of the optical fiber of the two optical-electrical composite cables. The two conductive pieces extend along the length direction of the cable slot and are fixed side by side in the interior of the cable slot. The two ends of the conductive piece include a sheath breaking structure, and the sheath breaking structure faces the side opening. The sheath breaking structure of one end of the two conductive pieces is used to pierce or scratch the sheath of one optical-electrical composite cable and electrically connect with the two wires of the one optical-electrical composite cable. The sheath breaking structure of the other end of the two conductive pieces is used to pierce or scratch the sheath of the other optical-electrical composite cable and electrically connect with the two wires of the other optical-electrical composite cable. The cover is used to close the side opening of the cable slot, and in the process of closing the side opening by the cover, the cover extrudes the optical-electrical composite cable in the cable slot, so that the sheath breaking structure pierces or scratches the sheath of the optical-electrical composite cable.

[0007] The technical solution provided by the present disclosure, when splicing two optical fiber composite cables using the optical fiber composite cable splicing box, first heat-welds the optical fibers of the two optical fiber composite cables, and causes the protective sleeve to enclose the heat-welded part of the optical fiber. Then, the protective sleeve is assembled in the cable groove of the base. Finally, the side opening is closed by using the upper cover, and the splicing operation is completed. In the process of closing the side opening by the upper cover, the upper cover extrudes the optical fiber composite cable in the cable groove, and the sheath breaking structure at one end of the two conductive pieces pierces or cuts the sheath of one optical fiber composite cable and electrically connects the two conductive pieces with the two wires of the optical fiber composite cable. The sheath breaking structure at the other end of the two conductive pieces pierces or cuts the sheath of the other optical fiber composite cable and electrically connects the two conductive pieces with the two wires of the optical fiber composite cable. In this way, the two conductive pieces realize the electrical connection of the two optical fiber composite cables.

[0008] It can be seen that, on the one hand, the present disclosure realizes the electrical connection of the two optical fiber composite cables by piercing or cutting the sheath of the optical fiber composite cable to electrically connect the conductive piece with the wire of the optical fiber composite cable. In this way, the two wires do not need to be stripped out, and the splicing operation is simplified. On the other hand, the assembly operation of the upper cover and the base is combined with the operation of realizing the electrical connection of the two optical fiber composite cables into the same operation, further simplifying the splicing operation.

[0009] In a possible implementation, the optical fiber composite cable splicing box includes two upper covers arranged along the length direction of the cable groove. The upper cover includes a first end close to the end opening and a second end away from the end opening. The second end is rotationally connected with the base, and the rotation axis is perpendicular to the length direction of the cable groove. The first end is used for clamping with the base.

[0010] The technical solution provided by the present disclosure, when using the upper cover to close the side opening, the user rotates (or flips) the upper cover until the first end of the upper cover clamps with the base. The operation mode of flipping increases the pressing force by the lever mechanism, which can improve the reliability of the sheath breaking structure breaking the sheath of the optical fiber composite cable, and the reliability of the electrical connection between the sheath breaking structure and the wire.

[0011] In a possible implementation, the cable groove includes two side openings arranged at intervals along the length direction of the cable groove. The two side openings are respectively arranged opposite to the sheath breaking structures at the two ends of the conductive piece, and respectively communicate with the two end openings. The two upper covers are respectively used for closing the two side openings.

[0012] The technical solution provided by the present disclosure, by arranging two side openings arranged at intervals, compared with one long side opening, the length of the side opening can be reduced, and the length of the upper cover is also reduced. In this way, the upper cover can avoid being too long to cause insufficient rigidity, and the reliability of the upper cover is improved, which is beneficial to guarantee the pressing force of the upper cover on the optical fiber composite cable.

[0013] In a possible implementation, the upper cover is used to be clamped with the base in a flat pressing manner.

[0014] In a possible implementation, the slot wall of the cable slot comprises two conductive piece accommodating grooves which extend along the length direction of the cable slot and are arranged side by side. The two conductive pieces are respectively located in the two conductive piece accommodating grooves, and the sheath breaking structure extends to the outside of the conductive piece accommodating groove. The arrangement of the conductive piece accommodating groove facilitates the accommodation and fixation of the conductive piece.

[0015] In a possible implementation, the two optical fiber cables to be connected by the optical fiber cable jointing box are butterfly type optical fiber cables. The sheath breaking structure is a thorn needle which is used to pierce the common sheath of the optical fiber cable, and the common sheath is used to cover the optical fiber and the two conductive wires of the butterfly type optical fiber cable. The thorn needle extends towards the side opening.

[0016] In a possible implementation, the upper cover comprises a clamping part which comprises a plurality of protrusions. The clamping part is used to squeeze the butterfly type optical fiber cable, and the clamping part is arranged opposite to the thorn needle when the upper cover closes the side opening. The common sheath is clamped between the clamping part and the thorn needle. The protrusion is a protruding tip or a protruding strip.

[0017] The technical solution provided by the present disclosure can better squeeze the common sheath by arranging the clamping part in the upper cover, so as to ensure that the thorn needle pierces the common sheath. On the other hand, under the action of the plurality of protrusions included in the clamping part, the clamping part bites the common sheath, thereby improving the tensile property of the optical fiber cable and reducing the possibility of the two optical fiber cables being pulled apart again.

[0018] In a possible implementation, along the length direction of the cable slot, the cable slot comprises one middle section and two side sections, and the middle section is arranged between the two side sections. The depth of the middle section is greater than the depth of the side section, and the width of the middle section is greater than the width of the side section. The middle section is used to accommodate the protective sleeve, and the two side sections are respectively used to accommodate the sheath breaking structure at the two ends of the conductive piece.

[0019] The technical solution provided by the present disclosure can better squeeze the common sheath by arranging the clamping part in the upper cover, so as to ensure that the thorn needle pierces the common sheath. On the other hand, under the action of the plurality of protrusions included in the clamping part, the clamping part bites the common sheath, thereby improving the tensile property of the optical fiber cable and reducing the possibility of the two optical fiber cables being pulled apart again.

[0020] In a possible implementation, the two optical-fiber cables to be spliced are flat optical-fiber cables. The sheath breaking structure includes two clamping arms, and each clamping arm includes a cutting blade on the side facing the other clamping arm. The two cutting blades are used to clamp and slit the wire sheath of the flat optical-fiber cable. The wire sheath is used to cover a wire.

[0021] The technical solution provided by the present disclosure can be used for flat optical-fiber cables. When the splicing operation is performed, the wire together with the wire sheath is first stripped from the common sheath. In this way, the cutting blade only needs to slit the wire sheath, thereby reducing the requirement for the structural strength of the sheath breaking structure and the pressing force required by the user. In addition, the sheath breaking structure includes two clamping arms, so that the two clamping arms can clamp the wire sheath to position the wire sheath and prevent the wire sheath from swinging to cause the wire sheath to be unable to be slit.

[0022] It should be noted that the wire together with the wire sheath can be stripped from the common sheath by using professional pliers. Compared with stripping the bare wire, the operation is relatively simple.

[0023] In a possible implementation, the upper cover includes a first pressing part and a second pressing part. The first pressing part and the second pressing part are used to press the wire sheath, and the sheath breaking structure is arranged between the first pressing part and the second pressing part when the upper cover closes the side opening. Since the sheath breaking structure is arranged between the first pressing part and the second pressing part, the first pressing part and the second pressing part can normally press the wire sheath and will not interfere with the sheath breaking structure.

[0024] In a possible implementation, each end of the conductive member includes two sheath breaking structures, and the two sheath breaking structures are arranged at intervals along the length direction of the cable slot. The upper cover further includes a third pressing part, and the third pressing part is used to press the wire sheath. The third pressing part is arranged between the first pressing part and the second pressing part, and the third pressing part is arranged between the two sheath breaking structures when the upper cover closes the side opening, and the two sheath breaking structures are arranged between the first pressing part and the second pressing part. By additionally arranging the third pressing part, the pressing effect on the wire sheath can be improved, and the stability of the wire sheath can be ensured.

[0025] In a possible implementation, the upper cover further includes a clamping part, and the clamping part includes a plurality of protrusions. When the upper cover closes the side opening, the clamping part is close to the end opening relative to the sheath breaking structure. The common sheath of the flat optical-fiber cable is clamped between the clamping part and the inner wall of the cable slot. In this way, the clamping part bites the common sheath under the action of the plurality of protrusions, thereby improving the tensile property of the optical-fiber cable and reducing the possibility that the two optical-fiber cables are broken again.

[0026] In a possible implementation, the optical fiber cable splice closure further includes two first rubber pads and two second rubber pads. The two first rubber pads are fixed inside the cable slot and arranged between the two end openings and the sheath breaking structure respectively. The two second rubber pads are fixed to the upper cover. When the upper cover closes the side opening of the cable slot, a channel is formed between the first rubber pad and the second rubber pad, the channel is communicated with the end opening and used for the optical fiber cable to pass through.

[0027] In the possible implementation, the first rubber pad and the second rubber pad are flexible, and the inner wall of the channel formed between the first rubber pad and the second rubber pad is close to the common sheath of the optical fiber cable. In this way, the liquid flowing into the interior of the optical fiber cable splice closure from the gap between the optical fiber cable and the end opening cannot continue to flow into the sheath breaking structure under the block of the first rubber pad and the second rubber pad, and the possibility of short circuit of the two conductive members is reduced.

[0028] In a possible implementation, the first rubber pad is in a U shape, and the second rubber pad is in a strip shape. The second rubber pad closes the opening of the first rubber pad, so that the channel is formed between the first rubber pad and the second rubber pad. BRIEF DESCRIPTION OF DRAWINGS

[0059] Fiber to the x (FTTx) extends optical fibers to enterprises, homes, rooms or desktops to provide network coverage for users in an all-optical networking manner. With the global deployment of FTTx, in addition to traditional pure optical cables, various cable designs of opto-electric hybrid cables or optical-electric hybrid cables have been increasingly used in recent years. Among them, FTTx includes fiber to the room (FTTR) and fiber to the home (FTTH) and the like.

[0060] Opto-electric hybrid cable, that is, optical fiber 101 and wire 102 (as shown in Figure 2 or Figure 13 ) are integrated in the same sheath. The opto-electric hybrid cable not only continues the advantages of high-speed communication of optical fiber, but also can supply power to the powered device for a distance of several meters to several hundred meters, to solve the actual scene problems such as inconvenience of power supply near the powered device, installation limited by the location of the power socket and the like. With the large use of opto-electric hybrid cables, the demand for maintenance and matching of opto-electric hybrid cables is increasingly strong.

[0061] Among them, the demand for maintenance and matching of opto-electric hybrid cables includes the demand for repairing the broken cable of the opto-electric hybrid cable, the demand for extending the opto-electric hybrid cable and the demand for loading the connector of the opto-electric hybrid cable. For the above scenarios, two opto-electric hybrid cables need to be connected. For example, Figure 1As shown in FIG. 1, the optical fiber composite cable 100 is shown in a cable breakage repair scenario. After the optical fiber composite cable 100 is broken into two, the two optical fiber composite cables 100 can be connected by the optical fiber composite cable splicing box 200.

[0062] The optical fiber composite cable splicing box 200 in the related art includes a bottom shell and a top cover, and a protective sleeve and a crimping terminal between the bottom shell and the top cover. In use of the optical fiber composite cable splicing box 200, the optical fibers 101 of the two optical fiber composite cables 100 are first heat fused, and the protective sleeve is used to enclose the heat fused part of the optical fibers 101. Then, two pairs of wires 102 included in the two optical fiber composite cables 100 are stripped, and the crimping terminal is used to crimp the two pairs of wires 102 to realize the electrical connection of the two pairs of wires 102. Finally, the bottom shell and the top cover are connected.

[0063] In the above splicing process, the two pairs of wires 102 included in the two optical fiber composite cables 100 need to be stripped, which is a relatively cumbersome operation, resulting in a relatively cumbersome overall splicing operation of the two optical fiber composite cables 100.

[0064] In view of the above technical problems, the present embodiment provides a novel optical fiber composite cable splicing box 200, which does not need to strip the wires 102 in the process of realizing the splicing of the two optical fiber composite cables 100, and the operation is relatively simple. Wherein, Figure 3 An external view of the optical fiber composite cable splicing box 200 is shown. Figure 4 An external view of the optical fiber composite cable splicing box 200 after splicing the two optical fiber composite cables 100 is shown. Figure 5 A schematic view of the internal structure of the optical fiber composite cable splicing box 200 after splicing the two optical fiber composite cables 100 is shown. Figure 6 A partial exploded view of the optical fiber composite cable splicing box 200 is shown.

[0065] As shown in FIG. 2, the optical fiber composite cable splicing box 200 includes a base 1, two conductive parts 2, and a top cover 3. As shown in FIG. 3 and FIG. 4, the base 1 includes a cable slot 11, and the cable slot 11 includes a side opening 111 and two end openings 112. The two end openings 112 are used for the two optical fiber composite cables 100 to pass through. The two conductive parts 2 each extend along the length direction of the cable slot 11 and are fixed side by side to the slot wall of the cable slot 11. The two conductive parts 2 are respectively used to electrically connect two pairs of wires 102 of the two optical fiber composite cables 100, so as to realize the electrical connection of the two optical fiber composite cables 100. In addition, the optical fibers 101 of the two optical fiber composite cables 100 are heat fused to realize the optical connection of the two optical fiber composite cables 100. In addition, in order to protect the heat fused part, the protective sleeve is used to enclose the heat fused part of the optical fibers 101. Figures 3-6 Figure 5 Figure 6 The two pairs of wires 102 included in the two optical fiber composite cables 100 are stripped, and the crimping terminal is used to crimp the two pairs of wires 102 to realize the electrical connection of the two pairs of wires 102. Finally, the bottom shell and the top cover are connected. Figure 7 ​​As shown, the optical fiber cable splicing box 200 can further include a protective sleeve 4, which surrounds the heat fusion portion of the optical fiber 101 and is located in the cable groove 11. It should be noted that Figure 5 The protective sleeve 4 is hidden in the cable groove 11.

[0066] In order to realize the electrical connection between the conductive member 2 and the conductive wire 102 without stripping the conductive wire 102, as shown in Figure 6 or Figure 15 The two ends of the conductive member 2 include a sheath breaking structure 22, which faces the side opening 111. The sheath breaking structure 22 at one end of the two conductive members 2 is used to pierce or scratch the sheath of one optical fiber cable 100 and electrically connect with the two conductive wires 102 of the optical fiber cable 100. The sheath breaking structure 22 at the other end of the two conductive members 2 is used to pierce or scratch the sheath of another optical fiber cable 100 and electrically connect with the two conductive wires 102 of the optical fiber cable 100. In this way, as shown in Figure 5 The two conductive members 2 respectively electrically connect the two conductive wires 102 of one optical fiber cable 100 with the two conductive wires 102 of another optical fiber cable 100, without stripping the conductive wire 102, and the operation is relatively simple.

[0067] In addition, as shown in Figure 7 The upper cover 3 is used to close the side opening 111 of the cable groove 11 to close the cable groove 11 and protect the devices inside the cable groove 11. Moreover, in the process of closing the side opening 111 by the upper cover 3, the upper cover 3 extrudes the optical fiber cable 100 in the cable groove 11, so that the sheath breaking structure 22 pierces or scratches the sheath of the optical fiber cable 100. In this way, the operation of closing the side opening 111 by the upper cover 3 is combined with the operation of realizing the electrical connection of the optical fiber cable 100 into the same operation, which further simplifies the operation of splicing the two optical fiber cables 100 and improves the splicing efficiency.

[0068] The fixing manner of the conductive member 2 is not limited in the embodiments of the present disclosure. In some examples, as shown in Figure 6 The groove wall of the cable groove 11 includes two conductive member accommodating grooves 110, which extend along the length direction of the cable groove 11 and are arranged side by side. The two conductive members 2 are respectively located in the two conductive member accommodating grooves 110, and the sheath breaking structure 22 of the conductive member 2 extends to the outside of the conductive member accommodating groove 110.

[0069] The connection manner of the upper cover 3 and the base 1 is not limited in the embodiments of the present disclosure. In some examples, as shown in Figures 3-7 The upper cover 3 is used to be clamped with the base 1 in a flat pressing manner. Wherein, Figure 7 A schematic diagram of the operation flow of the optical fiber cable splicing box 200 is shown.

[0070] AsFigure 7 As shown, first, the optical fibers 101 of the two optical fiber cables 100 are heat fused, and the heat fused parts of the optical fibers 101 are sleeved with the protective sleeves 4. Then, the two optical fiber cables 100 with the protective sleeves 4 are placed in the cable groove 11 of the base 1. The two optical fiber cables 100 pass through the two end openings 112, respectively. Finally, the upper cover 3 is used to close the side opening 111 in a flat pressing manner. During the process of closing the side opening 111 by the upper cover 3, the upper cover 3 extrudes the optical fiber cables 100, and the sheath breaking structure 22 pierces or cuts the sheath of the optical fiber cables 100, so that the electrical connection of the two optical fiber cables 100 is realized.

[0071] In some examples, as shown in FIG. 1, Figure 6 As shown in FIG. 1, the base 1 includes a plurality of buckles 116. As shown in FIG. 1, Figure 12 As shown in FIG. 1, the upper cover 3 includes a plurality of clamping strips 36, and the clamping strips 36 include clamping holes. The plurality of clamping strips 36 are clamped with the plurality of buckles 116, respectively.

[0072] In other examples, the upper cover 3 can also be connected with the base 1 in a flipped manner. For example, as shown in FIG. 2, Figure 8 As shown in FIG. 2, the optical fiber cable splicing box 200 includes two upper covers 3 arranged along the length direction of the cable groove 11. The upper cover 3 includes a first end 3a close to the end opening 112 and a second end 3b away from the end opening 112. The second end 3b is rotationally connected with the base 1, and the rotation axis I is perpendicular to the length direction of the cable groove 11. The first end 3a is used to be clamped with the base 1. In this way, when the upper cover 3 is used to close the side opening 111, the user flips the upper cover 3 until the first end 3a of the upper cover 3 is clamped with the base 1. The flipping operation increases the pressing force in the manner of a lever mechanism, which can improve the reliability of the sheath breaking structure 22 in breaking the sheath of the optical fiber cable 100 and the reliability of the electrical connection between the sheath breaking structure 22 and the wire 102.

[0073] In some examples, as shown in FIG. 1, Figure 8 As shown in FIG. 1, the cable groove 11 includes two side openings 111 arranged at intervals along the length direction of the cable groove 11. The two side openings 111 are oppositely arranged with the sheath breaking structures 22 at two ends of the conductive part 2, and the two side openings 111 are communicated with the two end openings 112, respectively. The two upper covers 3 are used to close the two side openings 111, respectively.

[0074] The technical scheme provided by the embodiments of the present disclosure can reduce the length of the side opening 111 by arranging two side openings 111 arranged at intervals, compared with one long side opening 111, and further reduce the length of the upper cover 3. In this way, the overlong upper cover 3 can be avoided to cause too small rigidity, and the reliability of the upper cover 3 is improved, which is conducive to guaranteeing the pressing force of the upper cover 3 on the optical fiber cable 100.

[0075] In some examples, as shown in Figure 17 The second end 3b of the upper cover 3 includes a rotating shaft 37 for rotating connection with the base 1.

[0076] In some examples, as shown in Figure 8 The first end 3a of the upper cover 3 includes a clamping hole 38, and the base 1 includes a clamping buckle 116 for clamping with the clamping hole 38.

[0077] Figure 9 A schematic diagram showing the operation flow of the optical fiber cable splicing box 200 is shown. As shown in Figure 9 First, one optical fiber cable 100 is inserted into the cable slot 11 of the optical fiber cable splicing box 200. Then, two optical fiber cables 100 are heat fused, and the protective sleeve 4 is used to wrap the heat fused part of the optical fiber 101. Then, the optical fiber cable splicing box 200 is slid so that the optical fiber cable splicing box 200 wraps the protective sleeve 4. Finally, the upper cover 3 is pressed to close the side opening 111. In the process of closing the side opening 111 by the upper cover 3, the optical fiber cable 100 is squeezed by the upper cover 3, and then the sheath breaking structure 22 pierces or cuts the sheath of the optical fiber cable 100, thereby realizing the electrical connection of the two optical fiber cables 100.

[0078] Currently, the optical fiber cable 100 includes a butterfly type optical fiber cable, which can also be referred to as a bow-type cable, and a flat type optical fiber cable, which can also be referred to as a flat cable. Among them, as shown in Figure 2 The butterfly type optical fiber cable includes a common sheath 103, which covers the optical fiber 101 and two wires 102. As shown in Figure 13 The flat type optical fiber cable includes a common sheath 103, two wire sheaths 104, and an optical fiber sheath 105. The common sheath 103 covers the two wire sheaths 104 and the optical fiber sheath 105. The wire sheath 104 covers the wire 102, and the optical fiber sheath 105 covers the optical fiber 101. For the above two types of optical fiber cables 100, the structure of the optical fiber cable splicing box 200 is also different. Next, exemplary descriptions are made respectively.

[0079] (1) The two optical fiber cables 100 spliced by the optical fiber cable splicing box 200 are butterfly type optical fiber cables (as shown in Figure 2 ). As shown in Figure 5 and Figures 7-9 The sheath breaking structure 22 is a needle for piercing the common sheath 103 of the optical fiber cable 100.

[0080] In some examples, as shown in Figure 6As shown, each end of the conductive member 2 includes a plurality of the piercing needles arranged in sequence along the length direction. In this way, the reliability of the piercing needles piercing the common sheath 103 of the optical fiber cable 100 can be improved, and the reliability of the electrical connection between the piercing needles and the conductive wire 102 can be ensured.

[0081] In some examples, as shown in Figure 6 As shown, the conductive member 2 includes a conductive strip 21 and the piercing needles arranged at both ends of the conductive strip 21. The conductive strip 21 and the piercing needles can be integrally formed.

[0082] In some examples, as shown in Figure 8 and Figure 12 As shown, the upper cover 3 includes a clamping portion 31 including a plurality of protrusions 311. When the upper cover 3 closes the side opening 111, the clamping portion 31 is arranged opposite to the sheath breaking structure 22. The common sheath 103 is clamped between the clamping portion 31 and the sheath breaking structure 22.

[0083] By arranging the clamping portion 31, on the one hand, the upper cover 3 can better squeeze the common sheath 103, ensuring that the piercing needles pierce the common sheath 103. On the other hand, under the action of the plurality of protrusions 311 included in the clamping portion 31, the clamping portion 31 clamps the common sheath 103, improving the tensile strength of the optical fiber cable 100 and reducing the possibility of the two optical fiber cables 100 being pulled apart again.

[0084] In some examples, as shown in Figure 8 As shown, the protrusions 311 included in the clamping portion 31 are spike structures, and a plurality of the spike structures are arranged in an array. In other examples, as shown in Figure 12 As shown, the protrusions 311 included in the clamping portion 31 are protrusions, and a plurality of the protrusions are arranged in the length direction of the cable groove 11.

[0085] Since the butterfly-shaped optical fiber cable only includes the common sheath 103, as shown in Figure 7 and Figure 9 As shown, after the protective sleeve 4 is heat-shrunk, the two ends of the protective sleeve 4 need to wrap around the common sheaths 103 of the two optical fiber cables 100. This makes the outer diameter of the heat-shrunk protective sleeve 4 greater than the outer diameter of the common sheath 103. In order to facilitate the accommodation of the protective sleeve 4, as shown in Figure 10 and Figure 11 As shown, along the length direction of the cable groove 11, the cable groove 11 includes a middle section 113 and two side sections 114, and the middle section 113 is arranged between the two side sections 114. The inner diameter of the middle section 113 is greater than the outer diameter of the protective sleeve 4, and the middle section 113 is used to accommodate the protective sleeve 4. In addition, as shown in Figure 10As shown, the edge section 114 is used to accommodate the sheath breaking structure 22, and also plays a role in limiting the common sheath 103, so the inner diameter of the edge section 114 cannot be too large, and the inner diameter of the edge section 114 is smaller than the inner diameter of the middle section 113. Specifically, the depth of the middle section 113 is greater than the depth of the edge section 114, and the width of the middle section 113 is greater than the width of the edge section 114.

[0086] In addition, as shown in Figure 11 and Figure 12 shown, the upper cover 3 includes an accommodation groove 39, the accommodation groove 39 is opposite to the middle section 113, and the accommodation groove 39 and the middle section 113 are used together to accommodate the protective sleeve 4.

[0087] It should be noted that, Figure 7 The schematic diagram of the operation process of the optical fiber cable splicing box 200 including the flat upper cover in the process of splicing the flat butterfly type optical fiber cable is shown. Figure 9 The schematic diagram of the operation process of the optical fiber cable splicing box 200 including the flip type upper cover in the process of splicing the flat butterfly type optical fiber cable is shown.

[0088] (2) In some examples, the two optical fiber cables 100 used for splicing by the optical fiber cable splicing box 200 are flat type optical fiber cables (such as Figure 13 As shown). For flat type optical fiber cables, if the wire 102 is not stripped from the common sheath 103 together with the wire sheath 104, the sheath breaking structure 22 needs to pierce or cut the common sheath 103 and the wire sheath 104 together to contact and electrically connect with the wire 102. This has higher requirements for the structural strength of the sheath breaking structure 22, and increases the operation force required to be applied by the user.

[0089] In order to solve the above technical problems, as shown in Figure 13 When splicing is performed, the wire 102 can be stripped from the common sheath 103 together with the wire sheath 104. In this way, the sheath breaking structure 22 only needs to pierce or cut the wire sheath 104, which reduces the requirement for the structural strength of the sheath breaking structure 22 and simplifies the operation force required to be applied by the user. It should be noted that the wire 102 can be stripped from the common sheath 103 together with the wire sheath 104 by using existing professional pliers, which is relatively simple compared with stripping the bare wire 102.

[0090] In addition, as shown in Figure 13 The wire sheath 104 has a small diameter and is cylindrical, so in order to prevent the wire sheath 104 from deflecting during the process of the piercing needle extruding the wire sheath 104, in some examples, as shown in Figures 14-16As shown, the sheath breaking structure 22 is fork-shaped. The sheath breaking structure 22 includes two clamping arms 221, each of which includes a cutting blade 220 on one side facing the other clamping arm 221. The two cutting blades 220 are used to clamp and slit the wire sheath 104 of the flat type of photoelectric composite cable. Among them, by setting the sheath breaking structure 22 to include two clamping arms 221, the two clamping arms 221 can clamp the wire sheath 104 to position the wire sheath 104 and prevent the wire sheath 104 from swinging and causing the wire sheath 104 to be unable to be slit.

[0091] In some examples, as shown in Figure 16 and Figure 17 The upper cover 3 includes a first extrusion part 32 and a second extrusion part 33 for extruding the wire sheath 104. When the upper cover 3 closes the side opening 111, the sheath breaking structure 22 is arranged between the first extrusion part 32 and the second extrusion part 33. Among them, since the sheath breaking structure 22 is arranged between the first extrusion part 32 and the second extrusion part 33, the first extrusion part 32 and the second extrusion part 33 can not only normally extrude the wire sheath 104, but also will not interfere with the sheath breaking structure 22.

[0092] In some examples, as shown in Figure 15 and Figure 16 Each end of the conductive member 2 includes two sheath breaking structures 22, which are arranged in the length direction of the cable groove 11. As shown in Figure 16 and Figure 17 The upper cover 3 further includes a third extrusion part 34 arranged between the first extrusion part 32 and the second extrusion part 33. When the upper cover 3 closes the side opening 111, the third extrusion part 34 is arranged between the two sheath breaking structures 22 and is used to extrude the wire sheath 104, and the two sheath breaking structures 22 are arranged between the first extrusion part 32 and the second extrusion part 33.

[0093] In some examples, the upper cover 3 includes two rows of first extrusion parts 32, two rows of second extrusion parts 33, and two rows of third extrusion parts 34. The two rows of extrusion parts are respectively opposite to the two conductive members 2.

[0094] In some examples, as shown in Figure 16 and Figure 17As shown, the upper cover 3 also includes a clamping part 31, which includes multiple protrusions 311. When the upper cover 3 closes the side opening 111, the clamping part 31 is close to the end opening 112 relative to the sheath breaking structure 22. The common sheath 103 of the flat optical fiber composite cable is used to clamp between the clamping part 31 and the inner wall of the cable groove 11. Thus, under the action of the multiple protrusions 311, the clamping part 31 grips the common sheath 103, improving the tensile strength of the optical fiber composite cable 100 and reducing the possibility of the two optical fiber composite cables 100 being broken again.

[0095] In some examples, such as Figure 17 As shown, the clamping part 31 includes protrusions 311 that are spike structures, with multiple spike structures arranged in an array. In other examples, such as Figure 12 As shown, the clamping part 31 includes protrusions 311 which are raised strips, and multiple raised strips are arranged at intervals along the length direction of the cable groove 11.

[0096] In some examples, such as Figure 15 As shown, the conductive component 2 includes a conductive strip 21 and two structural components located at both ends of the conductive strip 21. Each structural component includes two sheath-breaking structures 22. The conductive strip 21 and the structural components can be independent of each other.

[0097] in addition, Figure 18 This diagram illustrates the operational flow of the optoelectronic composite cable splice box 200, including its flip-top cover, during the splicing of a flat optoelectronic composite cable. Figure 18 As shown, firstly, a fiber optic composite cable 100 is passed through the cable groove 11 of the fiber optic composite cable splice box 200. Then, the optical fibers 101 of the two fiber optic composite cables 100 are thermally spliced, and a protective sleeve 4 is used to encircle the thermally spliced ​​portion of the optical fibers 101. Next, the fiber optic composite cable splice box 200 is slid so that the protective sleeve 4 and the conductor sheaths 104 of the two fiber optic composite cables 100 are encircled by the splice box 200. Finally, the upper cover 3 is flipped over, closing the side opening 111. During the process of the upper cover 3 closing the side opening 111, the upper cover 3 compresses the fiber optic composite cable 100, causing the sheath breaking structure 22 to pierce or tear the conductor sheath 104 of the fiber optic composite cable 100, thereby achieving the electrical connection between the two fiber optic composite cables 100.

[0098] Among them, such as Figure 18 As shown, for flat fiber optic composite cables, after the protective sleeve 4 is heat-fused, the loop around it is the conductor sheath 104, not the conductor sheath 104. Figure 9 The common sheath 103. Therefore. Figure 18 The diameter of the protective sleeve 4 is relatively small.

[0099] The optical-fiber cable junction box 200 can be applied in a water environment. Since the optical-fiber cable junction box 200 is internally provided with two conductive members 2, if water enters the interior of the optical-fiber cable junction box 200, the two conductive members 2 can be short-circuited. In some examples, in order to improve the waterproof performance of the optical-fiber cable junction box 200, the optical-fiber cable junction box 200 provided by the embodiment of the present disclosure further comprises a first rubber pad 5 and a second rubber pad 6. Wherein, Figure 19 a schematic view of the base 1 and the first rubber pad 5 is shown, Figure 20 a schematic view of the upper cover 3 and the second rubber pad 6 is shown, Figure 21 a schematic view of the first rubber pad 5 and the second rubber pad 6 is shown.

[0100] As shown in Figure 19 , the two first rubber pads 5 are fixed in the interior of the cable groove 11 and are arranged between the two end openings 112 and the sheath breaking structure 22, respectively. As shown in Figure 20 , the two second rubber pads 6 are fixed to the upper cover 3. When the upper cover 3 closes the side opening 111 of the cable groove 11, as shown in Figure 21 , a channel 50 is formed between the first rubber pad 5 and the second rubber pad 6, the channel 50 is communicated with the end opening 112 and is used for the optical-fiber cable 100 to pass through.

[0101] Wherein, the first rubber pad 5 and the second rubber pad 6 are flexible, so that the inner wall of the channel 50 formed between the first rubber pad 5 and the second rubber pad 6 closely abuts the common sheath 103 of the optical-fiber cable 100. In this way, the water flowing from the gap between the optical-fiber cable 100 and the end opening 112 into the interior of the optical-fiber cable junction box 200 cannot continue to flow to the sheath breaking structure 22 under the blockage of the first rubber pad 5 and the second rubber pad 6, thereby reducing the possibility of short-circuiting of the two conductive members 2.

[0102] In some examples, as shown in Figure 19 , for the mode that the upper cover 3 is clamped with the base 1 in a flat pressing manner, the two second rubber pads 6 are respectively fixed to the two ends of the upper cover 3. In other examples, for the mode that the two upper covers 3 are clamped with the base 1 in a flip manner, each second rubber pad 6 is fixed to the first end 3a of one upper cover 3.

[0103] In some examples, as shown in Figure 21 , the first rubber pad 5 is U-shaped, and the second rubber pad 6 is strip-shaped. The second rubber pad 6 closes the opening of the first rubber pad 5, so that the channel 50 is formed between the first rubber pad 5 and the second rubber pad 6. Of course, in other examples, the first rubber pad 5 can be strip-shaped, and the second rubber pad 6 can be U-shaped. Alternatively, the first rubber pad 5 and the second rubber pad 6 are both U-shaped, and the openings of the two U-shapes are opposite to each other, so that the channel 50 is formed between the first rubber pad 5 and the second rubber pad 6.

[0104] In some examples, as shown in FIG. 1, the base 1 includes a cable slot 11. Figure 19 As shown in FIG. 1, the cable slot 11 of the base 1 includes two first installation slots 115 arranged between the two end openings 112 and the sheath breaking structure 22, respectively, for accommodating the two first rubber pads 5.

[0105] In some examples, as shown in FIG. 1, the upper cover 3 includes two second installation slots 35, respectively, for accommodating the two second rubber pads 6. Figure 20

[0106] The above is only an optional embodiment of the present disclosure, and is not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.​
