Abstract
Description
Technical Field
[0001] The present application relates to the technical field of underwater cables, and in particular to a high-definition underwater cable. Background Art
[0002] When using some electronic devices underwater, it is usually necessary to configure a high-definition cable (HDMI cable) to transmit signals. For example, when taking photos or videos underwater, a high-definition cable is needed to connect the digital camera in the first waterproof housing and the display screen or burner in the second waterproof housing. The high-definition cable can transmit the high-definition signal to the display screen in real time to help underwater photographers quickly frame and shoot, or transmit the ultra-high-definition signal to the burner, and can also directly burn native videos, thereby greatly expanding the storage space of the digital camera; in addition, the high-definition cable can also transmit the signal or picture to the monitor on the ground in real time for the director or the audience to share. Therefore, a sealed connection is required between the high-definition cable and the waterproof housing to prevent water or seawater from penetrating into the waterproof housing, thereby avoiding damage to the electronic equipment placed in the waterproof housing.
[0003] At present, some high-definition cables are equipped with waterproof structures, which are connected between the cables and the waterproof shell for waterproofing. However, due to design limitations, when the high-definition cables are used in an environment with high water pressure, the waterproof structure will over-compress the cables due to the increased pre-pressure, and the outer sheath of the high-definition cables will be subjected to greater clamping force. The internal structure of the high-definition cables is composed of multiple thin wires, and the core diameter of these thin wires is only 0.2mm. When the clamping force is too large, it is easy to cause individual cores to break, thereby reducing the bandwidth and speed of the transmission signal, resulting in unstable signals or no signal output.

[0020] In one embodiment, the ratio of the distance from the first end face of the support ring to the second end face of the support ring to the distance from the first end face of the seal to the second end face of the seal is 1:(3-4).
[0021] In one embodiment, the support ring is sandwiched between the first layer and the second layer;

DETAILED DESCRIPTION
[0033] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.
[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).
[0036] See also Figure 1An embodiment of the present application provides an underwater high-definition cable for electrically connecting to an electronic device placed in a waterproof housing, including a wire 100 and a waterproof structure 200. The wire 100 is used to electrically connect to the electronic device, and the waterproof structure 200 is arranged around the outer periphery of the wire 100, one end of which is used to be sealed and connected to the wire 100, and the other end is used to be sealed and connected to the waterproof housing.
[0037] The waterproof structure 200 is sealed and connected between the wire 100 and the waterproof shell. When the high-definition cable is used underwater, water can be prevented from entering the interior of the waterproof shell from the connection between the wire 100 and the waterproof structure 200, and from the connection between the waterproof structure 200 and the waterproof shell, thereby preventing the electronic equipment in the waterproof shell from being soaked in water.
[0038] In one embodiment, the waterproof structure 200 is used to be detachably connected to the waterproof housing, so as to facilitate the connection and disassembly between the wire 100 and the electronic device.
[0039] The number of waterproof structures 200 can be set to one or two, which can be set specifically according to the application scenario. For example, when one end of the high-definition cable needs to be placed underwater and the other end needs to be placed above water, a waterproof structure 200 can be set; when both ends of the high-definition cable need to be placed underwater, two waterproof structures 200 can be set, and the two waterproof structures 200 are respectively placed at both ends of the wire 100. Preferably, the number of waterproof structures 200 is set to two. When this solution is adopted, when one end of the high-definition cable is placed above water, the waterproof structure 200 located above water may not be connected to the waterproof housing.
[0040] See also Figure 2 The wire 100 includes a wire body 101 and a wire quilt 102, and the wire quilt 102 is coated on the outer surface of the wire body 101. The wire body 101 includes multiple wire cores and a coating layer coated on the outside of the multiple wire cores. The coating layer can be selected according to specific requirements. For example, the coating layer can be at least one of an insulating layer, a braided layer, a waterproof layer, a shielding layer, an absorbing layer, etc., and the coating layer is not limited here. The wire quilt 102 is coated on the outer surface of the wire body 101 for waterproofing and protecting the wire body 101, for example, preventing the wire body 101 from being scratched during use.
[0041] See also Figure 1 and Figure 2The waterproof structure 200 includes a seal 10, a pressing assembly 20, a connecting assembly 30 and a supporting ring 40. The seal 10 is arranged around the periphery of the wire quilt 102, and the pressing assembly 20 is arranged around the periphery of the wire 100 and pressed on the side of the seal 10 away from the wire quilt 102, so that the seal 10 is closely attached to the wire quilt 102. The connecting assembly 30 is arranged around the periphery of the wire 100, and is used to seal and connect between the pressing assembly 20 and the waterproof shell; the supporting ring 40 is arranged around the circumference of the wire body 101, and the radial projection of the wire body 101 in the supporting ring 40 at least partially overlaps with the seal 10. Among them, the supporting ring 40 can be sandwiched between the wire body 101 and the wire quilt 102, can also be located inside the wire quilt 102, and can also be located on the outer surface of the wire quilt 102.
[0042] By adopting the above technical solution, by providing the pressing assembly 20 and the sealing member 10, when the sealing member 10 is tightly attached to the wire material layer 102 under the action of the pressing assembly 20, it can play a sealing role, so that the waterproof structure 200 is sealed and connected with the wire material 100; by providing the connecting assembly 30 to be sealed and connected between the pressing assembly 20 and the waterproof shell, the waterproof structure 200 can be sealed and connected with the waterproof shell. Therefore, one end of the waterproof structure 200 can be sealed and connected with the wire material 100 through the sealing member 10, and the other end of the waterproof structure 200 can be sealed and connected with the waterproof shell through the connecting assembly 30.
[0043] By arranging a support ring 40 on the circumference of the wire body 101, and making the radial projection of the support ring 40 along the wire body 101 located inside it overlap with the seal 10 at least partially, that is, the support ring 40 is arranged on the periphery of the wire body 101 and at least partially corresponds to the seal 10, the support ring 40 supports the seal 10; when the high-definition cable is used in an environment with high water pressure or water depth, the clamping assembly 20 is required to set a greater pre-pressure on the seal 10 and the wire layer 102. When the pre-pressure of the seal 10 increases, since the support ring 40 is arranged on the periphery of the wire body 101, supporting the seal 10, it can prevent the seal 10 from over-extruding the wire body 101, and the wire body 101 has a wire core inside, which can prevent the seal 10 from over-extruding the wire core, thereby avoiding the wire core from breaking.
[0044] See also Figure 2, the wire quilt 102 includes a first quilt 1021 and a second quilt 1022, the first quilt 1021 is coated on the outer surface of the wire body 101, the second quilt 1022 is coated on the outer surface of the first quilt 1021, the seal 10 is pressed by the pressing assembly 20 on the second quilt 1022, and the support ring 40 is sandwiched between the first quilt 1021 and the second quilt 1022. By arranging the support ring 40 between the first quilt 1021 and the second quilt 1022, when the high-definition cable is placed in an environment with excessive water pressure, the support ring 40 supports the second quilt 1022, and then supports the seal 10, so as to prevent the seal 10 from excessively squeezing the wire body 101 under the action of water pressure. It can be understood that in other embodiments, the support ring 40 is sandwiched between the wire body 101 and the first quilt 1021, or is located on the outer surface of the second quilt 1022.
[0045] The second coating 1022 is made of a hard and wear-resistant material, and can protect the wire body 101 .
[0046] In another embodiment, the wire quilt 102 includes a first quilt 1021, the first quilt 1021 is coated on the outer surface of the wire body 101, and the seal 10 is pressed against the first quilt 1021 by the pressing assembly 20; the support ring 40 is sandwiched between the wire body 101 and the first quilt 1021, or is located on the outer surface of the first quilt 1021. That is, in different embodiments, the wire quilt 102 is not limited to two layers, and the wire quilt 102 may also include only one first quilt 1021, and the first quilt 1021 may be made of a hard and wear-resistant material commonly used in the outer quilt of the wire. In other embodiments, the wire quilt 102 may also be composed of a three-layer or more layer structure, and the material of the wire quilt 102 may also be flexibly selected according to actual needs.
[0047] In one embodiment, the support ring 40 is sandwiched between the first layer 1021 and the second layer 1022, and the ratio of the thickness of the second layer 1022 to the diameter of the wire body 101 is 1:(7-13). The thickness of the second layer 1022 refers to the size of the second layer 1022 in the radial direction of the wire body 101 located inside the support ring 40.
[0048] With this arrangement, on the one hand, by arranging the support ring 40 between the wire body 101 and the second sheath 1022 , when the high-definition cable is used in an environment with excessive water pressure or water depth, the clamping assembly 20 is required to set a greater pre-pressure on the seal 10 and the second sheath 1022 . The support ring 40 supports the seal 10 and prevents the seal 10 from excessively squeezing the wire body 101 .
[0049] In the existing technical solution, since the support ring 40 is not provided, the overall size of the second layer 1022 or the high-definition cable may shrink after the high-definition cable is used or stored for a period of time, or when the high-definition cable is placed in an underwater environment below normal temperature, such as an underwater environment of 0 to 4°C; and the seal 10 is sealed by being tightly attached to the second layer 1022. When the seal 10 and the wire 100 are assembled, a set pre-pressure is applied to the seal 10 to achieve that the seal 10 is tightly attached to the second layer 1022; when the second layer 1022 or the overall size of the high-definition cable shrinks after the assembly with the seal 10 is completed, it will cause The pre-compression of the seal 10 is reduced, the sealing performance is reduced, and water seepage is caused; as mentioned above, the support ring 40 is located between the first layer 1021 and the second layer 1022, that is, located on the inner side of the second layer 1022, and the support ring 40 also supports the second layer 1022. By setting the thickness of the second layer 1022 to a ratio of 1: (7 to 13) to the diameter of the wire body 101, when the second layer 1022 shrinks, the maximum shrinkage is only 1: (7 to 13) of the diameter of the wire body 101, which will not have a substantial impact on the pre-compression set for the seal 10, thereby improving the reliability of the waterproof seal.
[0050] Therefore, this setting can not only enable the HD cable to be used in environments with greater water pressure or water depth, but also in water environments below normal temperature. For example, the HD cable can be used in the ocean and can be placed at a certain depth in the ocean (as the depth of the cable placed in the seawater increases, the water pressure gradually increases and the water temperature gradually decreases). The HD cable provided in this application can be used in water environments with a depth of up to 150m and a temperature of 0 to 4°C.
[0051] In a specific implementation, the ratio of the thickness of the second layer 1022 to the diameter of the wire body 101 may be 1:7, 1:9, 1:11, or 1:13. Preferably, the ratio of the thickness of the second layer 1022 to the diameter of the wire body 101 is 1:10.
[0052] In one embodiment, the support ring 40 is a support component made of stainless steel. Stainless steel is hard, has good compressive strength, and is not easily deformed. Of course, in other embodiments, the support ring 40 can also be made of other materials with reliable strength.
[0053] In one embodiment, the thickness of the support ring 40 is 0.3 mm to 1 mm. In this way, the strength of the support ring 40 can be ensured without making the support ring 40 too thick. The thickness of the support ring 40 refers to the radial dimension of the wire body 101 located inside the support ring 40. In a specific implementation, the thickness of the support ring 40 can be 0.3 mm or 0.5 mm or 0.8 mm or 1 mm. Preferably, the thickness of the support ring 40 is 0.5 mm.
[0054] In one embodiment, the support ring 40 and the seal 10 both have a first end face and a second end face that are arranged opposite to each other, the first end face of the support ring 40 and the first end face of the seal 10 are both arranged close to the connecting component 30, and the second end face of the support ring 40 and the second end face of the seal 10 are both arranged away from the connecting component 30.
[0055] Among them, the distance from the first end face of the support ring 40 to the first end face of the seal 10 along the axial direction of the wire body 101 in the support ring 40 is a first distance, and the distance from the second end face of the support ring 40 to the second end face of the seal 10 along the axial direction of the wire body 101 in the support ring 40 is a second distance, and the first distance is equal to the second distance. In other words, the support ring 40 is set corresponding to the middle part of the seal 10. Compared with the support ring 40 being set corresponding to one end of the seal 10, this setting method has a better supporting effect on the seal 10 by the support ring 40. Of course, in specific implementation, in other embodiments, it is also possible to set the support ring 40 away from the middle part of the seal 10.
[0056] In another embodiment, at least two support rings 40 may be provided, and the support rings 40 are arranged at intervals. In specific implementation, two, three, four, etc. support rings 40 may be provided, and adjacent support rings 40 may be arranged at equal intervals or at unequal intervals.
[0057] In one embodiment, the ratio of the distance from the first end face of the support ring 40 to the second end face of the support ring 40 to the distance from the first end face of the seal 10 to the second end face of the seal 10 is 1:(3-4). That is, in the axial direction of the wire body 101 inside the support ring 40, the ratio of the size (i.e., length) of the support ring 40 to the size (i.e., length) of the seal 10 is 1:(3-4), so that the support performance of the support ring 40 to the seal 10 can be guaranteed. In specific implementation, the length ratio can be 1:3 or 1:4.
[0058] In one embodiment, the sealing member 10 is made of sealing silicone and is annular in shape.
[0059] See also Figure 2The clamping assembly 20 includes a locking nut 21 and an adapter 22. The locking nut 21 and the adapter 22 are both sleeved on the periphery of the wire 100 and arranged along the extension direction of the wire 100. One end of the adapter 22 is threadedly connected to the locking nut 21, and the other end of the adapter 22 is sealedly connected to the connecting assembly 30. A receiving cavity 23 is formed between the adapter 22 and the locking nut 21, and the sealing member 10 is received in the receiving cavity 23. When the sealing member 10 is received in the receiving cavity 23, the first end face of the sealing member 10 abuts against the adapter 22, and the second end face of the sealing member 10 abuts against the locking nut 21. In a specific implementation, both ends of the adapter 22 are provided with external threads, and the locking nut 21 and the connecting assembly 30 are provided with internal threads matching the external threads, so that the adapter 22 is connected between the locking nut 21 and the connecting assembly 30.
[0060] The adapter connector 22 may be a straight connector or a bend connector. When the adapter connector 22 is a bend connector, the outlet direction of the wire 100 may be changed.
[0061] See also Figure 2 , a limiting step 221 is also provided at one end of the adapter 22 close to the locking nut 21. When the seal 10 is accommodated in the accommodating cavity 23, the end of the second layer 1022 abuts against the limiting step 221. During assembly, the support ring 40 is inserted between the wire body 101 and the second layer 1022. In order to ensure that the inserted position (i.e., the insertion depth) of the support ring 40 corresponds to the middle part of the seal 10, the limiting step 221 of the adapter 22 is used as a process reference to set the insertion depth of the support ring 40. When the end of the second layer 1022 abuts against the limiting step 221, it can be said that the support ring 40 corresponds to the middle part of the seal 10. Therefore, by providing the limiting step 221 at one end of the adapter 22 close to the locking nut 21 and making the end of the second layer 1022 abut against the limiting step 221, it is beneficial to position the support ring 40 in the middle part of the seal 10.
[0062] See also Figure 2 The connection assembly 30 includes a waterproof joint 31 and a hand nut 32; one end of the hand nut 32 is used for snap-fitting connection to the waterproof joint 31, and the other end of the hand nut 32 is used for threaded connection to the waterproof shell; the end of the waterproof joint 31 away from the hand nut 32 is used for sealing connection with the clamping assembly 20, and the end of the waterproof joint 31 close to the hand nut 32 is used for sealing connection with the waterproof shell when the hand nut 32 is threadedly connected to the waterproof shell.
[0063] In specific implementation, the end of the waterproof joint 31 away from the hand nut 32 is provided with an internal thread, and the waterproof joint 31 and the adapter joint 22 are threadedly connected through the external thread and the internal thread; and a sealing component is also provided between the waterproof joint 31 and the adapter joint 22 to achieve a sealed connection. In addition, a sealing component is also provided at the end of the waterproof joint 31 close to the hand nut 32 to achieve a sealed connection between the waterproof joint 31 and the waterproof housing.
[0064] By adopting the hand-tightening nut 32, the hand-tightening nut 32 and the waterproof shell are connected to each other in a detachable manner. On the one hand, the detachable connection between the waterproof structure 200 and the waterproof shell can be realized. On the other hand, after loosening the hand-tightening nut 32 to separate the waterproof structure 200 from the waterproof shell, the direction of the outlet line can be adjusted by rotating the adapter joint 22, thereby realizing on-site adjustment of the outlet direction of the wire 100.
[0065] See also Figure 1 and Figure 2 The waterproof structure 200 further includes a protective sleeve 50, which is sleeved on the periphery of the wire 100 and connected to the end of the pressing assembly 20 away from the connecting assembly 30. The protective sleeve 50 is configured to be threaded, which can prevent the wire 100 from being excessively bent and protect the wire 100. In a specific implementation, the protective sleeve 50 is provided with an internal thread, and the locking nut 21 is provided with an external thread, and the protective sleeve 50 and the locking nut 21 are threadedly connected.
[0066] See also Figure 1 and Figure 2 The waterproof structure 200 also includes a positioning ring 60, which is sleeved on the wire body 101 and pushed into the bottom of the inner hole of the adapter connector 22 (the end close to the waterproof connector 31) to assist in positioning the wire body 101. The positioning ring 60, the wire body 101 and the adapter connector 22 form an annular space 70 at one end close to the waterproof connector 31. In order to improve the connection firmness between the waterproof structure 200 and the wire 100, glue is further injected into at least the annular space 70. After the glue is cured, the wire body 101 and the adapter connector 22 can be bonded and fixed to avoid displacement of the wire body 101 and the adapter connector 22 when the high-definition cable is pulled outward at one end, which affects the assembly relationship of the waterproof structure 200 and the preset length of the wire body 101 entering the waterproof housing. In specific implementation, the height of the injected glue can extend to the space formed by the waterproof connector 31 and the wire body 101.
[0067] The steps of assembling the waterproof structure 200 and the wire 100 provided in one embodiment are as follows:
[0068] 1) Peeling off the second layer 1022 at one end of the wire 100 by a preset distance;
[0069] 2) inserting a support ring 40 between the second layer 1022 and the first layer 1021;
