Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a waterproof data cable. Background Art

[0002] See also Figure 1 , the existing data lines include:

[0003] Cable assembly 1;

[0004] Metal terminal 2;

[0005] An insulating base 3, wherein the insulating base 3 is provided with a cable cavity 301 for inserting the cable assembly 1, a terminal cavity 302 for accommodating the metal terminal 2, and a connecting passage 303 connecting the cable cavity 301 and the terminal cavity 302;

[0006] A filling block 5 , wherein the filling block 5 is located in the cable cavity 301 .

[0007] Specifically, during production, the cable assembly 1 needs to first enter the terminal cavity 302 through the connecting channel 303 and be electrically connected to the metal terminal 2. Then, waterproof glue is injected into the cable cavity 301. After the waterproof glue is cured, a filling block 5 can be formed to prevent subsequent water vapor from entering the terminal cavity 302 through the cable cavity 301.

[0008] In order to facilitate the passage of the cable assembly 1, the size of the communication channel 303 is generally slightly larger than the cable assembly 1, that is, a gap space is left between the inner wall of the communication channel 303 and the outer surface of the cable assembly 1. When injecting waterproof glue into the cable cavity 301, part of the waterproof glue (overflowing glue portion 501) is easy to flow into the terminal cavity 302 through the gap space, affecting the subsequent normal electrical connection of the metal terminal 2.

[0009] Therefore, it is necessary to improve the existing data cable to solve the problem that the waterproof glue easily flows into the terminal cavity through the gap space, resulting in failure of subsequent electrical connection.

[0010] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Utility Model Content

[0012] To achieve the above purpose, the utility model provides a waterproof data cable, including:

[0013] Cable assemblies;

[0014] Metal terminals;

[0015] An insulating base, wherein the insulating base is provided with a cable cavity for inserting the cable assembly, a terminal cavity for accommodating the metal terminal, and a communication channel connecting the cable cavity and the terminal cavity;

[0016] A rubber plug, which extends into the communication channel and is used to block the gap between the inner wall of the communication channel and the cable assembly;

[0017] A filling block is located in the cable cavity.

[0018] Optionally, the thickness of one end of the rubber plug inserted into the gap space gradually decreases toward the direction approaching the metal terminal.

[0019] Optionally, the size of the communication channel gradually decreases towards the terminal cavity.

[0023] Optionally, the rubber plug includes a plurality of plugs arranged one by one corresponding to each of the connecting channels, a main body connecting the plugs, and the embedded part fixed to a side of the main body away from the plugs.

[0024] Optionally, the plug, the main body, and the embedded portion are an integrally formed structure.

[0025] Optionally, the rubber plug is a silicone block or a rubber block.

[0026] The beneficial effect of the utility model is that it provides a waterproof data cable. During production, the cable assembly is firstly allowed to enter the terminal cavity through the connecting channel and be electrically connected to the metal terminal. Then, the rubber plug is inserted into the gap space through the cable cavity to seal the gap space. Finally, waterproof glue is injected into the cable cavity. After the waterproof glue is cured, a filling block can be formed.

[0027] In the above process, before the glue is injected, the gap space is first blocked with a glue plug, and after the glue is injected, the waterproof glue will not enter the terminal cavity through the gap space. Therefore, the waterproof data cable provided by the utility model can effectively solve the problem that the waterproof glue of the existing data cable easily flows into the terminal cavity through the gap space, resulting in subsequent electrical connection failure.

[0039] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0041] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0042] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0043] The utility model provides a waterproof data cable, which is suitable for application scenarios such as data transmission or power supply, and can effectively solve the problem that the waterproof glue of the existing data cable easily flows into the terminal cavity through the gap space, resulting in failure of subsequent electrical connection.

[0044] See also Figure 2 The waterproof data cable provided in this embodiment includes a cable assembly 1, a metal terminal 2, an insulating base 3, a rubber plug 4, and a filling block 5.

[0045] The insulating base 3 is provided with a cable cavity 301 for inserting the cable assembly 1, a terminal cavity 302 for accommodating the metal terminal 2, and a connecting channel 303 connecting the cable cavity 301 and the terminal cavity 302; the rubber plug 4 extends into the connecting channel 303 to seal the gap space between the inner wall of the connecting channel 303 and the cable assembly 1; the filling block 5 is located in the cable cavity 301.

[0046] When the waterproof data cable provided in this embodiment is produced, the cable assembly 1 is first allowed to enter the terminal cavity 302 through the connecting channel 303 and electrically connected to the metal terminal 2. Then, the rubber plug 4 is inserted into the gap space through the cable cavity 301 to seal the gap space. Finally, waterproof glue is injected into the cable cavity 301. After the waterproof glue is cured, the filling block 5 can be formed.

[0047] In the above process, before the glue is injected, the gap space is first blocked with the glue plug 4, and after the glue is injected, the waterproof glue will not enter the terminal cavity 302 through the gap space. Therefore, the waterproof data cable provided by the utility model can effectively solve the problem that the waterproof glue of the existing data cable easily flows into the terminal cavity 302 through the gap space, resulting in subsequent electrical connection failure.

[0048] In this embodiment, the cable assembly 1 includes a plurality of cable bodies; each of the cable bodies is correspondingly provided with one of the communication channels 303 .

[0049] See also Figure 3 and Figure 4 The rubber plug 4 includes a plurality of plugs 401 arranged one by one corresponding to each of the connecting channels 303 , a main body 402 connecting each of the plugs 401 , and an embedded portion 403 fixed to a side of the main body 402 away from each of the plugs 401 .

[0050] The embedding portion 403 protrudes toward the filling block 5 and is embedded in the filling block 5. It can be understood that the embedding portion 403 can be embedded in the filling block 5 to increase the contact area with the filling block 5, thereby improving the connection reliability with the filling block 5.

[0051] Optionally, the thickness of the end of the plug 401 inserted into the gap space gradually decreases toward the direction close to the metal terminal 2. Correspondingly, the size of the communication channel 303 gradually decreases toward the direction close to the terminal cavity 302. Such a structure is conducive to conveniently inserting the rubber plug 4 into the gap space through the cable cavity 301.

[0052] Optionally, each of the plug 401, the main body 402, and the embedded part 403 is an integrated structure to improve production efficiency. Further, the rubber plug 4 is made of a soft material such as a silicone block or a rubber block, and the soft rubber plug 4 is convenient for better filling the gap space.

[0053] In summary, the waterproof data cable provided by this embodiment has the following advantages: before glue injection, the gap space is first blocked with the glue plug 4, and after glue injection, the waterproof glue will not enter the terminal cavity 302 through the gap space. Therefore, the waterproof data cable provided by the utility model can effectively solve the problem that the waterproof glue of the existing data cable easily flows into the terminal cavity 302 through the gap space, resulting in subsequent electrical connection failure.
