[0005] In the prior art, during the use of three-wire core cables for communication, the cables will become messy due to the lack of a fixing function of a wire clamping assembly, which causes great inconvenience to daily inspection and maintenance. At the same time, for double-wire core cables, the quality of the wire cores will be affected due to the lack of fixing during use. For example, the cross-section of one end of the double-wire core cable is placed vertically, and the cross-section of the other end is placed horizontally. At this time, the cables between the two ends are no longer in a regular state, and the middle part of the cables will be twisted together. If the wire cores are kept in this state for a long time, the uneven force will affect the quality of the wire cores. The present invention passes the communication cables through the wire rack, and the cables that have entered the bottom of the wire rack are fixed at the lower end of the elastic sheet. Under the support, the cables placed at the bottom of the wire rack cannot escape. At this time, the double-core cable is placed in the first storage space and the second storage space.

Therefore, the first elastic straightening ring and the second elastic straightening ring will have a reaction force on the double-core cable to straighten the double-core cable. At the same time, the elastic positioning ring is supported at the interface of the double-core cable to further fix the double-core cable. At the same time, the double core will press down the elastic sheet below to further fix the cable on the bottom plate. At the same time, the elastic support column on the elastic sheet will have an upward force on the double-core cable, so that the double-core cable can better contact with each support ring.

[0006] Furthermore, a base plate is provided at the lower end of the wire rack, the vertical fixing plates are vertically connected to the base plate, both ends of the base plate are vertically fixedly connected to two support columns, the horizontal fixing plates are vertically connected to adjacent support columns, and the upper ends of the two support columns are vertically connected to opening and closing plates; before putting the cables into the wire rack, open the opening and closing plates to put the cables in, and then close the opening and closing plates. At this time, the cables in the wire rack are fixed in the wire rack, and when maintenance is needed, the opening and closing plates can be opened to take out the cables in the wire rack for maintenance.

[0007] Furthermore, the distance from the first oblique protection plate to the central axis is greater than the distance from the second oblique protection plate to the central axis, a V-shaped support space facing the direction of the opening and closing plate is formed between the two support protection plates, and the two elastic sheets form a V-shaped guide space facing the direction of the opening and closing plate.

The volume of the first storage space is greater than the volume of the second storage space. The first elastic straightening ring is located at the bottom of the first storage space, and the second elastic straightening ring is located at the bottom of the second storage space. The elastic positioning ring A portion of the upper end protrudes to the bottom of the first storage space, and the lower end of the elastic locking ring protrudes to the upper part of the second storage space; when the cable enters the bottom of the wire rack through the V-shaped guiding space to squeeze the elastic sheet, the V-shaped guiding space formed by the elastic sheet is larger at the top and smaller at the bottom, which can ensure that the cable entering the bottom cannot escape without the intervention of external force. At the same time, the cable that will enter the bottom of the wire rack later can enter normally, and then the cable is placed in the second storage space formed by the second oblique protective plate, and finally the last cable is placed in the first storage space hole formed by the first oblique protective plate. At this time, the cable in the second storage space can be well fixed because the space it is in is smaller than the upper space and it is pressed by the cable placed in the first storage space.

[0011] When the cables are placed in the first storage space and the second storage space, the cables will exert a force on the first elastic straightening ring and the second elastic straightening ring under the action of gravity. At this time, the first elastic straightening ring and the second elastic straightening ring will also exert a reaction force on the cables to protect and fix the cables. The elastic clamping rings both protrude in the vertical direction of the second oblique protection plate. The cables in the first storage space and the second storage space both exert a force on the elastic clamping rings. Therefore, the elastic clamping rings simultaneously exert a reaction force on the two cables in the first storage space and the second storage space to further fix the two cables.

[0014] Furthermore, a first communication cable is placed in the V-shaped supporting space. The first communication cable is an integral cable, which includes a first wire core portion and a second wire core portion that are parallel and fixed to each other. Two V-shaped recesses are formed at the connection between the first wire core portion and the second wire core portion. The two V-shaped recesses are symmetrically arranged about the central axis. The cross-section of the first wire core portion is larger than the cross-section of the second wire core portion. The first wire core portion is located above the second wire core portion. The first wire core portion is placed in the first storage space. A portion of the lower side of the first wire core portion protrudes into the second storage space. The second wire core portion is placed in the second storage space. The lower end of the first wire core portion is abutted against the two On a first elastic support surface, the lower end of the first wire core is simultaneously against two elastic fixing surfaces, the lower end of the second wire core is against two second elastic supporting surfaces, and the lower end of the second wire core is against two third elastic supporting surfaces, and two elastic clamping rings are respectively inserted into two V-shaped recesses; the guide spacing formed by the two elastic sheets allows the cable to enter the bottom of the wire rack through the guide spacing, and at the same time, the elastic support column provided on the elastic sheet will form an upward reaction force on the upper cable after being subjected to the downward pressure of the cable, so that the upper cable can better contact the support ring and the fixing ring, and further fix the cable.

A storage space is formed in the cabinet body 101. The cabinet door 102 is hinged on the cabinet body 101 and closes the storage space. The support assembly 103 comprises a plurality of support plates. The plurality of support plates are located in the storage space and fixed on the inner side wall of the cabinet body 101.

Protection plate 5, each first inclined protection plate 5 is connected to a first transverse protection plate 6 at the lower end, each first transverse protection plate 6 is connected to a second inclined protection plate 7 which gradually approaches the central axis downward at one end close to the central axis at one end, each second inclined protection plate 7 is connected to a second transverse protection plate 8 at the lower end, the second transverse protection plate 8 is vertically connected to the vertical fixed plate 4, a first elastic straightening ring 9 is provided above the two first transverse protection plates 6, an elastic positioning ring 11 is provided at one end close to the first transverse protection plate 6 of the two second inclined protection plates 7, a second elastic straightening ring 10 is provided above the two second transverse protection plates 8, an accommodating space is formed between the two vertical fixed plates 4, an elastic sheet 12 is provided at the upper end of each vertical fixed plate 4, the two elastic sheets 12 are located in the accommodating space, the distance between the two elastic sheets 12 gradually decreases in the downward direction, and elastic support columns 23 are provided on the two elastic sheets 12.

[0030] In the prior art, during the use of communication wire core cables, the cables will become messy due to the lack of a fixing function of a wire clamping assembly, which causes great inconvenience to daily inspection and maintenance. At the same time, for double-core cables, the quality of the wire cores will be affected due to the lack of fixing during use. For example, the cross-section of one end of the double-core cable is placed vertically, and the cross-section of the other end is placed horizontally. At this time, the cables between the two ends are no longer in a regular state, and the middle part of the cable will be twisted together. The wire cores remain in this state for a long time, and the uneven force on the wire cores will affect the quality of the wire cores. The present invention passes the cable through the wire rack 1. The cables that have entered the bottom of the wire rack 1 are supported by the elastic sheet 12, and the cables placed at the bottom of the wire rack 1 cannot escape without external force. At this time, the first communication cable (the present invention) The first communication cable and the second communication cable 121 (both of which are double-core cables) are placed in the first storage space 18 and the second storage space 19. The first communication cable will cause downward pressure on the first elastic straightening ring 9 and the second elastic straightening ring 10. Therefore, the first elastic straightening ring 9 and the second elastic straightening ring 10 will have a reaction force on the first communication cable to straighten the first communication cable. At the same time, the elastic positioning ring 11 is pressed against the V-shaped recess of the first communication cable to further fix the first communication cable. At the same time, the first communication cable will press down the elastic sheet 12 below to further fix the second communication cable 121 on the bottom plate 13 of the wire rack 1. At the same time, the elastic support column 23 on the elastic sheet 12 will have an upward force on the first communication cable, so that the first communication cable can better contact with each support ring.

[0031] A bottom plate 13 is provided at the lower end of the wire rack 1, and the vertical fixing plates 4 are vertically connected to the bottom plate 13. Two supporting columns 14 are vertically fixedly connected at both ends of the bottom plate 13. The horizontal fixing plates 3 are vertically connected to adjacent supporting columns 14, and the upper ends of the two supporting columns 14 are vertically connected with opening and closing plates 15. Before putting the cables into the wire rack 1, open the opening and closing plates 15 to put the cables in, and then close the opening and closing plates 15. At this time, the cables in the wire rack 1 are fixed in the wire rack 1. When maintenance is needed, the opening and closing plates 15 can be opened to take out the cables in the wire rack 1 for maintenance.

[0032] The distance from the first oblique protection plate 5 to the central axis is greater than the distance from the second oblique protection plate 7 to the central axis. A V-shaped support space 16 facing the opening and closing plate 15 is formed between the two support protection plates 2. The two elastic sheets 12 form a V-shaped guide space 17 facing the opening and closing plate 15. The V-shaped support space 16 is located above the V-shaped guide space 17. The V-shaped support space 16 includes a first storage space 18 and a second storage space 19 connected up and down. The first storage space 18 is located between the first oblique fixing plates 5 of the two support protection plates 2, and the second storage space 19 is located between the second oblique fixing plates 7 of the two support protection plates 2. The volume of the first storage space 18 is greater than the volume of the second storage space 19. The first elastic straightening ring 9 is located at the bottom of the first storage space 18, and the second elastic straightening ring 10 is located at the bottom of the second storage space 19. A portion of the upper end of the elastic clamping ring 11 protrudes to the bottom of the first storage space 18, and the lower end of the elastic clamping ring 11 protrudes to the second storage space 19. Upper part; apply a downward force to the second communication cable to squeeze the elastic sheet 12. After the second communication cable enters the storage space formed by the vertical fixed plate 4 through the V-shaped guide space 17, since the V-shaped guide space 17 formed by the elastic sheet 12 is larger at the top and smaller at the bottom, it can ensure that the second communication cable that enters the bottom first cannot escape without the intervention of external force. At the same time, the cable that will enter the storage space formed by the vertical fixed plate 4 later can enter normally, and then the second core portion 162 of the first communication cable is placed in the second storage space 19 formed by the second oblique protective plate 7, and finally, the first core portion 161 of the first communication cable is placed in the first storage space 18 hole formed by the first oblique protective plate 5. At this time, the second core portion 162 in the second storage space 19 can be well fixed because the space it is in is smaller than the upper part and it is pressed by the first core portion 161 placed in the first storage space 18.

[0033] The first elastic straightening ring 9 protrudes above the first horizontal protection plate 6, one end of the bottom of the first elastic straightening ring 9 is fixedly connected to the lower end of the first inclined protection plate 5, and the other end of the bottom of the first elastic straightening ring 9 is fixedly connected to the upper end of the second inclined protection plate 7, and the tops of the two first elastic straightening rings 9 both form a first elastic supporting surface 20.

[0034] The elastic retaining ring 11 protrudes in the vertical direction of the second oblique protection plate 7 , the bottom of the elastic retaining ring 11 is fixedly connected to the upper end of the second oblique protection plate 7 , and the tops of the two elastic retaining rings 11 both form elastic fixing surfaces 22 .

[0035] The second elastic straightening ring 10 protrudes obliquely above the second transverse protection plate 8, one end of the bottom of the second elastic straightening ring 10 is fixedly connected to the lower end of the second oblique protection plate 7, and the other end of the bottom of the second elastic straightening ring 10 is fixedly connected to the end of the second transverse protection plate 8 away from the central axis, and the tops of the two second elastic straightening rings 10 both form a second elastic support surface 21.

[0036] When the first wire core 161 is placed in the first storage space 18 and the second wire core 162 is placed in the second storage space 19, the first communication cable will exert a force on the first elastic straightening ring 8 and the second elastic straightening ring 10 under the action of gravity. At this time, the first elastic straightening ring 9 and the second elastic straightening ring 10 will also exert a reaction force on the cable to protect and fix the cable. The upper ends of the two elastic retaining rings 11 protrude to the lower part of the first storage space 18, and the lower ends protrude to the upper part of the second storage space 19. The first wire core 161 in the first storage space 18 and the second wire core 162 in the second storage space 19 both exert a force on the elastic retaining ring 11. Therefore, the elastic retaining ring 11 exerts a reaction force on the two cables in the first storage space 18 and the second storage space 19 at the same time, further fixing the first communication cable.

[0037] The support columns 14 are all provided with blind grooves, and the horizontal fixing plates 3 vertically protrude into the blind grooves of the adjacent support columns 14. The cross section of the horizontal fixing plates 3 is rectangular, and the cross section of the blind groove is rectangular. The central axis of the blind groove is collinear with the central axis of the horizontal fixing plates 3. The bottom plate 13 is provided with two second blind grooves, and the lower ends of the vertical fixing plates 4 protrude into the second blind grooves. The cross section of the vertical fixing plates 4 is rectangular, and the cross section of the second blind groove is rectangular. The central axis of the second blind groove is collinear with the central axis of the vertical fixing plates 4. The horizontal fixing plates 3 protrude into the blind grooves of the adjacent support columns 14, and the cross sections thereof are the same, so that the structure of the wire rack 1 has strong stability. The vertical fixing plates 4 protrude into the grooves of the bottom plate 13 to further enhance the structural stability of the wire rack 1.

[0038] The ends of the two elastic sheets 12 away from the central axis are fixedly connected to the corresponding vertical fixing plate 4, the tops of the elastic sheets 12 are fixedly connected to elastic support columns 23, and the elastic support columns 23 are formed with third elastic support surfaces 231. The lower side of the elastic sheet 12 is formed with an arc-shaped guide portion, and the lower end of the arc-shaped guide portion is formed with an elastic abutting sheet body. A guide spacing 24 is formed between the arc-shaped guide portions of the two elastic sheets 12, and the distance between the two elastic abutting sheets gradually decreases in the vertical downward direction. The lower ends of the two elastic sheets 12 are placed with second communication cables 121, and the upper sides of the second communication cables 121 are provided with a plurality of elastic support plates 231. The peripheral surface is abutted against the bottom edge of the elastic abutting sheet; the guide spacing 24 formed by the two elastic sheets 12 allows the second communication cable 121 to enter the storage space formed by the vertical fixing plate 4 through the guide spacing 24, and at the same time, the elastic support column 23 arranged on the elastic sheet 12 will form an upward reaction force on the first communication cable above after being subjected to the downward pressure of the first communication cable, so that the first communication cable located above the elastic support column 23 can better contact the first elastic straightening ring 9, the second elastic straightening ring 10 and the elastic positioning ring 11, thereby further fixing the first communication cable. When it is necessary to remove the first communication cable and the second communication cable for maintenance, first take out the first communication cable located on the top, apply an upward force to the second communication cable to squeeze the elastic sheet 12, and the elastic sheet 12 gradually deforms upward. When the second communication cable at the bottom 1 of the wire rack passes through the elastic sheet 12, the vibration generated when the elastic sheet 12 is reset can shake off the dust on the wire rack 1. When the elastic sheet 12 is reset, the bottom edges of the elastic supporting sheet can gradually approach each other and slide along the upper circumference of the first communication cable in the process and finally keep the two elastic supporting sheets in parallel.

[0039] A first communication cable is placed in the V-shaped support space 16. The first communication cable is an integral cable, which includes a first wire core portion 161 and a second wire core portion 162 which are parallel and fixed to each other. Two V-shaped recesses are formed at the connection between the first wire core portion 161 and the second wire core portion 162. The two V-shaped recesses are symmetrically arranged about the central axis. The cross section of the first wire core portion 161 is larger than the cross section of the second wire core portion 162. The first wire core portion 161 is located above the second wire core portion 162. The first wire core portion 161 is placed in the first storage space 18. A portion of the lower side of the first wire core portion 161 protrudes into the second storage space 19. The second wire core portion 162 is placed in the second storage space 19. The lower end of the first wire core portion 161 is abutted against the two first elastic supporting surfaces 20. The lower end of the first wire core portion 161 is abutted against the two elastic fixing surfaces 22 at the same time. The lower end of the second wire core 162 is abutted against the two second elastic supporting surfaces 21, and the lower end of the second wire core 162 is abutted against the two third elastic supporting surfaces 231, and the two elastic locking rings 11 are respectively inserted into the two V-shaped recesses; when the first communication cable is placed in the V-shaped supporting space 16, the second wire core 162 is located in the second storage space 19, and the first wire core 161 is located in the first storage space 18, and the first storage space 18 is located above the second storage space 19, so the first wire core 161 is located above the second wire core 162, and the cross-section of the first wire core 161 is larger than the cross-section of the second wire core 162, so the second wire core 162 is fixed in the second storage space 19, and the opening and closing plate 15 above the first wire core 161 is closed, and the first communication cable is fixed in the wire rack 1. Furthermore, when the first communication cable is placed into the V-shaped support space 16, the first wire core 161 exerts a force on the first elastic aligning ring 9 and the elastic retaining ring 11. At this time, the first wire core 161 is fixed in the correct shape under the elastic force of the elastic aligning ring 9 and the elastic retaining ring 11. When the second wire core 162 is placed into the second storage space 19, the second wire core 162 exerts a force on the second elastic aligning ring 10. The second wire core 162 is fixed in the correct shape under the elastic force of the second elastic aligning ring 10. The V-shaped depression formed by the first wire core 161 and the second wire core 162 is fixed by the elastic retaining ring.
