Description

Technical Field

[0001] The invention relates to the technical field of composite cables in cable technology, in particular to a flat buffer composite cable. Background Art

[0002] In the prior art, composite cables have many application scenarios. The required performance of composite cables is that they need to have certain compression and buffering capabilities. For example, when the cable is subjected to greater pressure, it can produce better buffering function. Then, after being compressed, it also needs to have better recovery performance and be able to return to its original shape and structure. There are also many structures of buffered cables in the prior art.

[0003] For example: the "buffered automotive cable" disclosed in the publication (announcement) number: CN111899936A, the technical solution includes a cable core, a connecting layer, a positioning shaft, a circumferential connecting component, and a radial connecting component; the multiple cable cores of the present invention can have a good elastic buffering process when squeezed in any direction; the present invention installs inner radial elastomers between the positioning shaft and the multiple cable cores, and the inner radial elastomers are distributed along the radial direction of the positioning shaft, so that after being squeezed, the structure of the multiple cable cores and the multiple outer circumferential elastomers is more stable, and the radial elastic floating capacity is increased, so that the present invention increases the resistance and buffering capacity of the present invention from the circumferential and radial directions.

[0004] For example: the "anti-interference buffered composite optical cable" disclosed in the publication (announcement) number: CN108717880A, the technical scheme includes a main body, a first insulating filling layer, a power line and a control line, the power line is arranged in the middle position of the main body, and is arranged on the upper and lower sides of the power line, and two control lines are symmetrically arranged about the power line, and the gap between the power line and the control line is filled with the first insulating filling layer; the power line is dumbbell-shaped, and a cavity is arranged inside the power line; the setting of the shielding belt can avoid mutual interference between the control line cores, and the setting of the buffer convex body can play a good buffering and protective role for the control line, thereby avoiding the control line from being deformed by strong extrusion; the layout of the present invention is reasonable, and the insulation, high temperature resistance, corrosion resistance and flame retardant properties are good. At the same time, it has good tensile strength, compression resistance and anti-sagging capabilities, thereby greatly improving the safety and reliability of the cable.

[0005] The above technical solutions all increase the compression resistance and buffering performance of the cable by arranging an elastomer inside the cable. However, in the above technical solutions, the arrangement of the elastomer is usually not comprehensive enough, and only a unidirectional elastomer structure can be set, and the buffering orientation is not comprehensive enough; in addition, the buffering capacity of the elastomer is not strong enough, and the cable cannot be effectively restored to its original state, and the overall rebound effect needs to be further strengthened.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a flat buffer composite cable with a reasonable structure and strong resilience and buffering performance. Summary of the invention

[0007] The purpose of the present invention is to provide a flat buffer composite cable in view of the shortcomings of the prior art; the technical solution is as follows:

[0008] A flat buffer composite cable comprises two composite cable cores arranged inside, each composite cable core is coated with a semicircular left frame and a semicircular right frame on the outside, and the left frame and the right frame form an integral circular frame that covers the composite cable core as a whole; the two composite cable cores are arranged in parallel, and a transversely arranged spring buffer mechanism is correspondingly installed between the right frame of the left composite cable core and the left frame of the right composite cable core, and the left frame of the left composite cable core and the right frame of the right composite cable core are correspondingly coated with a wrapping layer on the outside, so that the two composite cable cores and the circular frame outside the composite cable core are wrapped into a cable as a whole, and the internal spring buffer mechanism is also wrapped inside accordingly, and the spring buffer mechanism supports the composite cable core on both sides;

[0009] An outer shielding layer is also arranged outside the wrapping layer, and an outer sheath is correspondingly arranged outside the outer shielding layer. The outer sheath is flat in structure as a whole, and the two internal composite cable cores press the outer sheath to both sides under the action of the spring buffer mechanism.

[0010] Furthermore, the spring buffer mechanism includes a spring sleeve arranged on the left frame and a spring sleeve rod arranged at a corresponding position on the right frame, the spring sleeve rod correspondingly extends into the spring sleeve, and a spring part is correspondingly fixed in the spring sleeve, and the spring sleeve rod correspondingly presses on the spring part; the spring part pushes up the spring sleeve rod and the spring sleeve to both sides, thereby pushing up the composite cable core to both sides.

[0011] Furthermore, the transversely arranged spring buffer mechanisms are evenly spaced between the two composite cable cores, and buffer gaps are formed between adjacent spring buffer mechanisms.

[0012] Furthermore, a buffer area is formed between the wrapping layer and the right side frame of the left composite cable core and the left side frame of the right composite cable core, and a strip-shaped buffer plate of a corresponding shape is installed in the buffer area, and the buffer plate is embedded in the buffer area.

[0013] Furthermore, a buffer plate is correspondingly embedded in the buffer area on the upper and lower sides, and the buffer gap between the transversely arranged spring buffer mechanisms is correspondingly located between the buffer plates, and a vertical spring buffer mechanism is correspondingly arranged between the upper and lower buffer plates.

[0014] Furthermore, the vertically arranged spring buffer mechanism includes a spring sleeve arranged on the upper buffer plate and a spring sleeve rod arranged on the lower buffer plate. A spring part is correspondingly installed in the spring sleeve, and the spring sleeve rod is correspondingly extended into the spring sleeve to press the spring part. The spring sleeve rod and the spring sleeve are correspondingly arranged in the buffer gap, and support the winding layer and the outer sheath on the outside upward and downward.

[0015] Furthermore, the composite cable core includes an innermost conductor, an insulating layer arranged outside the conductor, an inner shielding layer arranged outside the insulating layer, and an inner sheath arranged outside the inner shielding layer.

[0016] Beneficial effects: The present invention has the following beneficial effects:

[0017] 1) In the present invention, two semicircular skeletons are arranged outside the two composite cable cores. First, the two composite cable cores are protected as a whole by the skeletons. The skeletons can be specifically arranged as ceramic skeletons, etc., which have good compression resistance;

[0018] 2) In the present invention, an elastic buffer mechanism is arranged between the semicircular skeletons on both sides, and the elastic buffer mechanism can push the composite cable cores on both sides outward, and then the outer sheath wraps the composite cable core as a whole from the outside. Therefore, when the whole cable is squeezed in the left and right directions, the elastic buffer mechanism can squeeze and buffer inward to offset this part of the pressure, and when the external force disappears, it can return to its original position under the action of the elastic buffer mechanism, and has good buffering and compression resistance performance;

[0019] 3) The elastic buffer mechanism in the present invention is specifically configured as a structure of a spring sleeve, a spring sleeve rod and a spring member. The internal spring member can correspondingly lift the spring sleeve and the spring sleeve rod. The overall structure is configured very reasonably, and the buffering performance is achieved through the specific spring member. The elastic buffer mechanism is evenly spaced, and a buffer gap can be formed between adjacent ones, so that installation space can be vacated for installing other components, and the structure is reasonable.

[0020] 4) In the present invention, a buffer plate is installed in the space of the buffer area. The buffer plate is located between the wrapping layer and the left and right frames. This area is exactly an empty area. The buffer plate is installed here to provide better compression resistance from the upper and lower positions, and the structure is reasonably set;

[0021] 5) The present invention also provides a vertical buffer elastic mechanism, which is arranged on the buffer plate and is fixed on the buffer plate. The specific installation position is corresponding to the buffer gap formed by the transversely arranged buffer elastic mechanism. On the one hand, the installation position is very reasonable; on the other hand, the vertical buffer elastic mechanism can provide better buffering performance in the vertical direction. If pressure is applied from top to bottom, compression buffering will be generated at the upper and lower positions, and then reset accordingly, and the structure is reasonable.

[0022] 6) The vertically arranged elastic buffer mechanism in the present invention is also arranged in the structural form of a spring sleeve, a spring sleeve rod and a spring member, and cooperates with the horizontally arranged elastic buffer mechanism to achieve the overall buffering performance of the cable from both the horizontal and vertical directions, and the structural setting is very reasonable.

[0032] In this embodiment, an outer shielding layer 6 is further provided outside the wrapping layer 5, and an outer sheath 7 is correspondingly provided outside the outer shielding layer 6. The outer sheath 7 is a flat structure as a whole, and the two internal composite cable cores 1 press against the outer sheath 7 on both sides under the action of the spring buffer mechanism 4.

The spring sleeve rod 9 of this embodiment extends into the spring sleeve 8, and a spring member 10 is fixed in the spring sleeve 8 of this embodiment. The spring sleeve rod 9 of this embodiment is pressed on the spring member 10. The spring member 10 of this embodiment pushes up the spring sleeve rod 9 and the spring sleeve 8 to both sides, thereby pushing up the composite cable core 1 to both sides.

[0034] The transversely arranged spring buffer mechanisms 4 are evenly spaced between the two composite cable cores 1 , and buffer gaps 11 are formed between adjacent spring buffer mechanisms 4 .

[0035] In the technical solution of this embodiment, firstly, two semicircular skeletons are set outside the two composite cable cores, and the two composite cable cores are protected as a whole by the skeletons.

[0041] The spring buffer mechanism 4 of this embodiment includes a spring sleeve 8 arranged on the left frame 2 and a spring sleeve rod 9 arranged at a corresponding position on the right frame 3. The spring sleeve rod 9 of this embodiment extends into the spring sleeve 8, and a spring member 10 is fixed in the spring sleeve 8 of this embodiment. The spring sleeve rod 9 of this embodiment is pressed on the spring member 10. The spring member 10 of this embodiment pushes up the spring sleeve rod 9 and the spring sleeve 8 to both sides, thereby pushing up the composite cable core 1 to both sides.

[0042] The transversely arranged spring buffer mechanisms 4 are evenly spaced between the two composite cable cores 1 , and buffer gaps 11 are formed between adjacent spring buffer mechanisms 4 .

[0043] A buffer area 12 is formed between the wrapping layer 5 of this embodiment and the right skeleton 3 of the left composite cable core 1 and the left skeleton 2 of the right composite cable core 1.
