[0023] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 2 As shown, this embodiment provides a pressure-resistant flexible cable 100, including an inner sheath 10, multiple electrical units 20, a buffer assembly 30, and multiple opening and closing assemblies 40.

[0025] The inner sheath 10 is made of insulating plastic and is approximately a hollow cylindrical structure, with a receiving cavity 11 inside. Multiple electrical units 20 are located within the receiving cavity 11 and are evenly spaced around the axis of the inner sheath 10. The buffer assembly 30 includes a support member 31 and multiple sliding members 32. Each sliding member 32 corresponds one-to-one with each electrical unit 20, meaning the number of sliding members 32 and their positions are identical. A sliding member 32 is positioned between any two adjacent electrical units 20. The sliding member 32 can slide relative to the support member 31, with one end elastically connected to the support member 31 and the other end abutting against the inner sheath 10.

[0026] The plurality of opening and closing assemblies 40 are arranged one-to-one with the plurality of electrical units 20, that is, the number of the plurality of opening and closing assemblies 40 is the same as that of the plurality of electrical units 20 and the positions are one-to-one corresponding. The opening and closing assembly 40 comprises an opening and closing piece 41 and a first elastic piece 42, one end of the opening and closing piece 41 is slidably connected to the support piece 31, and the other end of the opening and closing piece 41 abuts against the electrical unit 20 to the inner protective layer 10, on the one hand, the electrical unit 20 is clamped between the opening and closing piece 41 and the inner protective layer 10 to realize the position fixation of the electrical unit 20, on the other hand, the inner protective layer 10 is supported by the electrical unit 20 to ensure the roundness of the entire compression-resistant flexible cable 100. The first elastic piece 42 is configured to provide an elastic force to the opening and closing piece 41, and the elastic force is configured to move the opening and closing piece 41 away from the side of the electrical unit 20.

[0027] When the compression-resistant flexible cable 100 is subjected to an external force to make the sliding piece 32 slide away from the side of the inner protective layer 10, the sliding piece 32 can provide a moving space, based on the elastic force, the opening and closing piece 41 can move in the moving space away from the side of the electrical unit 20, thereby providing the electrical unit 20 with a space to move inward (i.e., away from the side of the inner protective layer 10) through the opening and closing piece 41. When the compression-resistant flexible cable 100 is no longer subjected to the external force, the sliding piece 32 slides towards the side of the inner protective layer 10, and the sliding piece 32 can abut against its adjacent opening and closing piece 41 to make the opening and closing piece 41 abut against the electrical unit 20 to move towards the inner protective layer 10, thereby resetting the electrical unit 20 to continue abutting against the inner protective layer 10.

[0028] Thus, the compression-resistant flexible cable 100 of the present application, when the part of the compression-resistant flexible cable 100 corresponding to the sliding piece 32 is subjected to an external force, the sliding piece 32 slides away from the side of the inner protective layer 10, and based on the elastic connection of the sliding piece 32 and the support piece 31, the external force received by the compression-resistant flexible cable 100 can be buffered. In addition, during the sliding process of the sliding piece 32, the opening and closing piece 41 can move away from the side of the electrical unit 20, thereby providing a space for the electrical unit 20 to move inward, avoiding the direct action of the external force on the electrical unit 20 through the inner protective layer 10 to cause damage to the electrical unit 20, thereby improving the compression resistance of the entire compression-resistant flexible cable 100.

[0029] Please refer to Figures 1 to 2 In an embodiment, the support piece 31 is made of insulating plastic material, and the support piece 31 comprises a central part 311 and a plurality of extension parts 312, the plurality of extension parts 312 are arranged around the outer peripheral surface of the central part 311, the plurality of extension parts 312 are arranged corresponding to the plurality of electrical units 20, and one extension part 312 is arranged between any two adjacent electrical units 20.

[0030] The center portion 311 can have a circular or rectangular cross-sectional shape, and the central axis of the center portion 311 coincides with the central axis of the inner protective layer 10. A plurality of extension portions 312 are arranged at equal intervals around the outer circumferential surface of the center portion 311. A weight-reducing hole 310 is formed at the center of the center portion 311 to reduce the weight of the support member 31 and improve the bending performance of the support member 31.

[0031] In the present embodiment, the number of extension portions 312 is four, the four extension portions 312 are distributed in a cross shape, and the extension direction of any one of the extension portions 312 is parallel to the direction of one radial direction of the compression-resistant flexible cable 100, so that any two adjacent extension portions 312 are arranged perpendicular to each other. The number of electrical units 20 and opening and closing assemblies 40 is four, and the space between any two adjacent extension portions 312 accommodates one electrical unit 20.

[0032] It can be understood that in other embodiments, the number of electrical units 20 can also be three or five or other numbers, and the specific number of electrical units 20 can be selected according to actual needs.

[0033] In the present embodiment, the electrical unit 20 includes a conductor 21 and an insulating layer 22, and the conductor 21 is made of conductive materials such as aluminum or copper. The insulating layer 22 is made of insulating materials, and the insulating layer 22 covers the outer periphery of the conductor 21 to play an insulating role. It is worth noting that according to actual design needs, the electrical unit 20 can also be provided with shielding structures or protective structures, etc. Other structural components of the electrical unit 20 except the conductor 21 and the insulating layer 22 are not limited in the present application.

[0034] Please refer to Figures 1 to 2 In an embodiment, each sliding member 32 includes a sliding portion 322, a support portion 323, and an abutting portion 321. One end of the sliding portion 322 is elastically connected to the support member 31, the support portion 323 is connected to the other end of the sliding portion 322, and the support portion 323 is configured to support the inner protective layer 10.

[0035] The extension portion 312 is internally provided with a movable cavity 3120, and the end of the extension portion 312 away from the center portion 311 is provided with a first sliding groove 3121, the extension direction of the first sliding groove 3121 is the same as the extension direction of the extension portion 312, and the first sliding groove 3121 communicates with the movable cavity 3120. The extension direction of the sliding portion 322 is the same as the extension direction of the extension portion 312, and the sliding portion 322 is slidably arranged in the first sliding groove 3121, so that the sliding portion 322 can slide relative to the extension portion 312.

[0036] It is worth noting that each of the four extensions 312 is provided with a first sliding groove 3121, and the four sliding members 32 are respectively slidably partially accommodated in the four first sliding grooves 3121, so as to realize the sliding of the four sliding members 32 relative to the four extensions 312 respectively, and the sliding direction of each sliding member 32 is parallel to the extension direction of the extension 312 where the sliding member 32 is located.

[0037] The support part 323 is located outside the movable cavity 3120, and the cross-sectional shape of the support part 323 is generally curved. The support part 323 is arranged in close contact with the inner circumferential surface of the inner protective layer 10. Along the circumferential direction of the inner protective layer 10, the two ends of the support part 323 are respectively close to the two adjacent electric units 20, so that the inner circumferential surface of the entire inner protective layer 10 can be supported by the four support parts 323 and the four electric units 20 to a large extent, so as to ensure the roundness of the entire compression-resistant flexible cable 100. In addition, the support part 323 is arranged in close contact with the inner protective layer 10, and the support part 323 has a relatively large arc length. When the inner protective layer 10 is subjected to an external force, the pressure can be uniformly distributed on the support part 323, so as to avoid stress concentration and damage to the inner protective layer 10 caused by the sliding member 32.

[0038] In the embodiment, the buffer assembly 30 further includes a plurality of second elastic members 33, which are arranged corresponding to the plurality of sliding members 32. One end of each second elastic member 33 is elastically connected to the support member 31, and the other end of the second elastic member 33 is elastically connected to the end of the sliding member 32 away from the inner protective layer 10.

[0039] The abutting part 321 is located in the movable cavity 3120, and the abutting part 321 is connected to the end of the sliding part 322 extending into the movable cavity 3120. The second elastic member 33 is located in the movable cavity 3120, and the extension direction of the second elastic member 33 is parallel to the extension direction of the extension part 312 where the second elastic member 33 is located. One end of the second elastic member 33 is connected to the cavity wall on the side of the movable cavity 3120 away from the inner protective layer 10, and the other end of the second elastic member 33 is connected to the end of the abutting part 321 away from the sliding part 322.

[0040] The second elastic member 33 is a compression spring or the like. The second elastic member 33 always provides an elastic force to the sliding member 32 to move towards the side of the inner protective layer 10, so that the support part 323 can abut against the inner circumferential surface of the inner protective layer 10. When the sliding member 32 is subjected to an external force and moves away from the inner protective layer 10, the second elastic member 33 is continuously compressed. After the external force is removed, the second elastic member 33 can push the sliding member 32 to reset, and the inner protective layer 10 is also supported by the support part 323 to restore to the original state. At the same time, when the sliding member 32 is subjected to an external force, the second elastic member 33 can also buffer the external force, thereby improving the compression resistance of the compression-resistant flexible cable 100.

[0041] Please combine again Figures 1 to 2In an embodiment, the plurality of sliding members 32 are correspondingly arranged with the plurality of extending portions 312, and the sliding members 32 are slidably connected to the corresponding extending portions 312. The opposite sides of the extending portions 312 are respectively provided with the opening and closing members 41, and the two opening and closing members 41 are slidably connected to the extending portions 312, and the sliding directions of the two opening and closing members 41 are perpendicular to each other, and the two opening and closing members 41 respectively abut the two different electrical units 20.

[0042] The opening and closing assembly 40 includes the two opening and closing members 41 and the two first elastic members 42, and the two first elastic members 42 respectively provide elastic force to the two opening and closing members 41. One of the two opening and closing members 41 is located between the first side of the electrical unit 20 and the corresponding sliding member 32, and abuts the first side. The other of the two opening and closing members 41 is located between the second side of the electrical unit 20 and the corresponding sliding member 32, and abuts the second side.

[0043] The four opening and closing assemblies 40 are correspondingly arranged with the four extending portions 312, and in the direction perpendicular to the extending direction of the extending portions 312, the two opening and closing members 41 of the same opening and closing assembly 40 are respectively located on the opposite sides of the corresponding extending portion 312, that is, the two opening and closing members 41 of the same opening and closing assembly 40 respectively abut the different electrical units 20. The two opening and closing members 41 of the adjacent two opening and closing assemblies 40 abut the same electrical unit 20, so as to ensure the stability of the electrical unit 20 when the electrical unit 20 is abutted on the inner protective layer 10.

[0044] The opening and closing member 41 includes the main body portion 411, the first branch portion 413 and the second branch portion 412. The main body portion 411 is located between the adjacent electrical unit 20 and the extending portion 312, and the main body portion 411 is arranged along the extending direction of the extending portion 312. In the direction perpendicular to the extending direction of the extending portion 312, the side of the main body portion 411 close to the electrical unit 20 is provided with the arc-shaped surface P3, the arc-shaped surface P3 can be attached to the surface of the electrical unit 20, and the first branch portion 413 and the second branch portion 412 are connected to the side of the main body portion 411 close to the extending portion 312. In the extending direction of the extending portion 312, the first branch portion 413 and the second branch portion 412 are arranged in a spaced manner.

[0045] The arc-shaped surfaces P3 of the two opening and closing members 41 are arranged in a perpendicular manner, and the arc-shaped surfaces P3 of the two opening and closing members 41 respectively abut the two ends of the side of the electrical unit 20 away from the inner protective layer 10, so as to ensure the position stability of the electrical unit 20 when the compression-resistant flexible cable 100 is not subjected to external force.

[0046] In the embodiment, the opening and closing member 41 is slidably connected to the support member 31, and the sliding direction of the opening and closing member 41 is perpendicular to the sliding direction of the sliding member 32 adjacent to the opening and closing member 41. The side wall of the sliding member 32 is provided with a first inclined surface P1, and the side of the opening and closing member 41 close to the sliding member 32 is provided with a second inclined surface P2, the first inclined surface P1 and the second inclined surface P2 are arranged in parallel, and the first inclined surface P1 abuts against the second inclined surface P2 when the sliding member 32 slides.

[0047] The second sliding groove 3122 is arranged on the opposite sides of the extension part 312 in a direction perpendicular to the extension direction of the extension part 312, and the extension direction of the second sliding groove 3122 is perpendicular to the extension direction of the extension part 312, and the second sliding groove 3122 communicates with the movable cavity 3120. One end of the second branch part 412 is connected to the main body part 411, and the other end of the second branch part 412 is slidably arranged in the second sliding groove 3122, so that the second branch part 412 can slide relative to the extension part 312. The end of the second branch part 412 away from the main body part 411 extends into the movable cavity 3120 and abuts against the abutting part 321.

[0048] The cross-sectional shape of the abutting part 321 is approximately isosceles trapezoidal, and the opposite sides of the abutting part 321 are respectively provided with a first inclined surface P1 in a direction perpendicular to the extension direction of the sliding part 322, and the two first inclined surfaces P1 are symmetrically arranged with the center section of the extension part 312 as the reference. The end of the second branch part 412 of the two opening and closing members 41 adjacent to the extension part 312 where the sliding part 322 is located extends into the movable cavity 3120 and is provided with a second inclined surface P2. The two second inclined surfaces P2 are correspondingly arranged with the two first inclined surfaces P1, and the second inclined surface P2 is arranged in parallel with the corresponding first inclined surface P1, so that the two first inclined surfaces P1 of the sliding member 32 abut against the two second inclined surfaces P2 on both sides at the same time, thereby realizing that the sliding member 32 abuts against the two opening and closing members 41 adjacent to it at the same time. The first inclined surface P1 and the second inclined surface P2 abut against each other to form a wedge structure between the abutting part 321 and the second branch part 412.

[0049] The first inclined surface P1 is arranged obliquely from the end close to the inner sheath 10 towards the center part 311 and towards the opening and closing member 41 adjacent to it.

[0050] Therefore, when the sliding member 32 slides along the extension direction of the extension part 312 towards the center part 311, due to the arrangement of the first inclined surface P1, there is a certain movement space between the opening and closing member 41 and the abutting part 321 in a direction perpendicular to the sliding direction of the sliding member 32, thereby making the opening and closing member 41 slide towards the side of the sliding member 32 under the action of the first elastic member 42, and further making the opening and closing member 41 move away from the electrical unit 20 it abuts against, thereby providing space for the electrical unit 20 to move away from the side of the inner sheath 10.

[0051] When the sliding member 32 slides along the extension direction of the extension part 312 towards the inner sheath 10, the sliding member 32 can abut the opening and closing member 41 on both sides thereof to slide synchronously and reversely perpendicular to the sliding direction of the sliding member 32, so as to push the electric unit 20 to move towards the inner sheath 10 against the elastic force provided by the first elastic member 42 to the opening and closing member 41, until the electric unit 20 is reset to abut the inner sheath 10.

[0052] In the present embodiment, the first elastic member 42 is arranged along the sliding direction of the opening and closing member 41, one end of the first elastic member 42 is elastically connected to the support member 31, and the other end of the first elastic member 42 is elastically connected to the opening and closing member 41.

[0053] Along the extension direction of the extension part 312, the first branch part 413 is arranged at the side of the extension part 312 close to the inner sheath 10. The side of the extension part 312 close to the inner sheath 10 is provided with a first mounting part 3123, the first mounting part 3123 is provided with a third sliding groove 3124, the extension direction of the third sliding groove 3124 is perpendicular to the extension direction of the extension part 312, and the first branch part 413 is partially and slidably accommodated in the third sliding groove 3124 to realize the sliding of the first branch part 413 relative to the extension part 312. The end of the first branch part 413 away from the main body part 411 is provided with a second mounting part 4130. The second mounting part 4130 is arranged at the side of the first mounting part 3123 close to the sliding member 32. The first elastic member 42 is located between the first mounting part 3123 and the second mounting part 4130, and one end of the first elastic member 42 is elastically connected to the first mounting part 3123, and the other end of the first elastic member 42 is elastically connected to the second mounting part 4130. The first elastic member 42 is a compression spring or the like, and the first elastic member 42 always provides an elastic force to the second mounting part 4130 to move towards the side of the sliding member 32, and further provides an elastic force to the opening and closing member 41 to move towards the side of the sliding member 32, so that when the sliding member 32 slides towards the side away from the inner sheath 10 to provide the above-mentioned moving space to the opening and closing member 41, the opening and closing member 41 can move towards the sliding member 32 under the action of the first elastic member 42.

[0054] It can be understood that the number of the first elastic member 42 corresponding to each opening and closing member 41 can be set to two or the like to ensure the stability of the sliding of the opening and closing member 41 under the action of the first elastic member 42. The position of the first elastic member 42 relative to the opening and closing member 41 can be selected according to actual needs, which is not specifically limited in the present application.

[0055] In the embodiment, the part of the inner protective layer 10 that is abutted by the sliding member 32 is the first part, and the part of the inner protective layer 10 that is abutted by the electric unit 20 is the second part. When one first part is located at the top end of the pressure-resistant flexible cable 100, the upper half part corresponding to the first part of the pressure-resistant flexible cable 100 is subjected to external force, the part of the pressure-resistant flexible cable 100 corresponding to the first part is the concentrated stress point, and the first part is forced to make the sliding member 32 slide towards the support member 31, the second elastic member 33 plays a buffering role, and in the sliding process, the two opening and closing members 41 abutted by the sliding member 32 move towards each other, so that the two electric units 20 adjacent to the sliding member 32 have an inwardly biased activity space, and when the upper half part of the pressure-resistant flexible cable 100 is subjected to external force, the second part is also subjected to force and acts on the electric unit 20, the activity space makes the electric unit 20 inwardly extruded by the inner protective layer 10, and the opening and closing member 41 synchronously provides an activity space for the electric unit 20, thereby avoiding a large force directly extruding the electric unit 20 and causing damage to the electric unit 20.

[0056] In addition, when the bottom end of the pressure-resistant flexible cable 100 is placed on the ground, the bottom end of the pressure-resistant flexible cable 100 is also subjected to force when the top end of the pressure-resistant flexible cable 100 is subjected to force, so that the corresponding sliding member 32 slides, and the second elastic member 33 corresponding to the sliding member 32 buffers the pressure, thereby relieving the pressure on the top end of the pressure-resistant flexible cable 100 by simultaneously buffering the pressure through the two second elastic members 33.

[0057] It is worth noting that when the part of the pressure-resistant flexible cable 100 corresponding to the other first part is subjected to external force, the pressure-resistant mechanism is basically the same as described above, and will not be described again.

[0058] When one second part is located at the top end of the pressure-resistant flexible cable 100 (or the second part is the main stress point), the upper half part corresponding to the second part of the pressure-resistant flexible cable 100 is subjected to external force, the part of the pressure-resistant flexible cable 100 corresponding to the second part is the concentrated stress point, the inner protective layer 10 is subjected to force and extrudes the electric unit 20 to move inwardly, the electric unit 20 further acts on the two opening and closing members 41 abutting the electric unit 20, the inclined wedge structure formed between the opening and closing member 41 and the sliding member 32 makes the sliding member 32 slide inwardly to extrude the second elastic member 33, and the second elastic member 33 can buffer the pressure. In addition, the two opening and closing members 41 are extruded by the electric unit 20 to slide towards the side of the corresponding sliding member 32, thereby making the two opening and closing members 41 generally tend to open, thereby providing a space for the electric unit 20 to move inwardly, thereby avoiding that the electric unit 20 is directly subjected to a large pressure and damaged when external force is concentrated on the part corresponding to the electric unit 20.

[0059] It is worth noting that when the abutting portion 321 and the second branch portion 412 constitute a wedge structure, the first inclined surface P1 and the second inclined surface P2, and the specific structure of the abutting portion 321 and the second branch portion 412, such as the wedge angle and the friction angle, can be set according to actual needs to avoid self-locking problems, so that the sliding member 32 can drive the second branch portion 412 to slide as a driving element, and the second branch portion 412 can also drive the sliding member 32 to slide as a driving element. When the sliding member 32 is driven to slide by the one-side opening and closing member 41, the opening and closing member 41 on the other side of the sliding member 32 will not hinder the sliding of the sliding member 32.

[0060] Please also refer to Figures 1 to 2 In an embodiment, the anti-pressure flexible cable 100 further comprises an outer protective layer 50 wrapped around the outer periphery of the inner protective layer 10. The outer protective layer 50 comprises a shielding layer, a shielding insulation layer, an outer protective sleeve, and the like. In addition, according to the specific application scenario of the anti-pressure flexible cable 100, the outer protective layer 50 can further comprise a waterproof layer, a fireproof layer, and other necessary layer structures for constructing a flexible cable.

However, those skilled in the art can understand that various changes and replacements can be made to the specific embodiments of the present application without departing from the scope of the present application.
