The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1 , Figure 2 A waterproof wire is shown, comprising a wire body 500, a first terminal 100, a second terminal 200 and a partition piece 600. The first terminal 100 and the second terminal 200 are respectively arranged at the two ends of the wire body 500 that need to be connected, and the ends of the wire body 500 can be quickly electrically connected to each other through the mutual connection of the first terminal 100 and the second terminal 200; the partition piece 600 is arranged on the first terminal 100, and correspondingly, a partition groove 212 is opened on the second terminal 200. When the first terminal 100 is connected to the second terminal 200, the partition piece 600 is inserted into the partition groove 212. At this time, the partition piece 600 and the partition groove 212 cooperate with each other to separate the electrical connection between the first terminal 100 and the second terminal 200, and the partition piece 600 is made of insulating material and has very good insulation, so that a short circuit can be effectively prevented at the connection between the first terminal 100 and the second terminal 200.

[0035] In some embodiments, see Figure 2 , Figure 3 , Figure 7The first terminal 100 includes a first body 11 and a first conductive member 12. The first body 11 is provided with an insertion cavity 111. The partition member 600 and the first conductive member 12 are both connected to the first body 11 and are located inside the insertion cavity 111. The partition member 600 includes a plurality of spacers 61 arranged at angles to each other. A first conductive member 12 is arranged between two adjacent spacers 61. The first conductive member 12 is used to connect the circuit. The spacer 61 is used to separate adjacent first conductive members 12 to avoid short circuit or signal interference between the first conductive members 12.

[0036] See also Figure 2 , Figure 3 , Fig. 9 The second terminal 200 includes a second body 21 and a second conductive member 22. The second conductive member 22 is arranged on the second body 21 and is used to be electrically connected to the first conductive member 12, so that the circuit is electrically connected; the plug-in end of the second body 21 is provided with a plurality of partition grooves 212 at angles to each other, and a second conductive member 22 is arranged between two adjacent partition grooves 212. The partition grooves 212 separate the adjacent second conductive members 22, so that the creepage distance between the adjacent second conductive members 22 along the outer surface of the second body 21 is greatly increased, and the possibility of short circuit or signal interference between the second conductive members 22 is reduced. In addition, the partition grooves 212 can also make it difficult for water droplets to adhere to the plug-in end of the second body 21, thereby preventing short circuit or signal interference caused by water droplets between adjacent second conductive members 22.

[0037] In actual application, when the first terminal 100 and the second terminal 200 are plugged into each other, the second conductive member 22 and the first conductive member 12 are plugged into each other and fit together, and the partition 61 of the partition member 600 is inserted into the partition groove 212, so that the adjacent first conductive members 12 and the adjacent second conductive members 22 are multiple-partitioned, and the creepage distance (the distance between two conductors along the outer surface of an object) between the adjacent first conductive members 12 and the adjacent second conductive members 22 is greatly increased, thereby greatly reducing the possibility of short circuits and signal interference.

[0038] In some embodiments, Figure 7 As shown, the above-mentioned spacer 61 includes a first part 611 and a second part 612, and the first part 611 and the second part 612 are connected to each other. Along the direction from the connecting end to the free end of the spacer 61, the length of the first part 611 is shorter than the length of the second part 612, and the side of the first part 611 away from the second part 612 is connected to the side wall of the insertion cavity 111. The first part 611 is used to increase the integrity of the first body 11 to facilitate injection molding operations during reprocessing, and the second part 612 is used to isolate the first conductive member 12.

[0039] like Fig. 9As shown, the partition groove 212 includes a deep portion and a shallow portion. The deep portion is located in the middle of the plug-in end of the second main body 21 and is used to insert the second portion 612 of the spacer 61. The shallow portion is located at the edge of the plug-in end of the second main body 21, and the shallow portion is connected to the side of the plug-in end of the second main body 21 to form a notch, which is used to be plugged with the first portion 611 of the spacer 61.

[0040] It is understandable that in actual processing and manufacturing, the first terminal 100 and the second terminal 200 are often produced by integral injection molding. By designing the partition 61 as the first part 611 and the second part 612, and designing the partition groove 212 as the deep part and the shallow part respectively, the structure of the first terminal 100 and the second terminal 200 is more integrated, which is convenient for injection molding processing.

[0041] In some embodiments, Figure 8 As shown, the thickness of the above-mentioned separator 61 is greater than 0.6 mm and less than 2 mm. Within the above-mentioned thickness range, it can be avoided that the separator 61 is too thin and is easy to deform during the processing. If the separator 61 is too thick, the distance between the first conductive member 12 and the surface of the separator 61 will be too small. If the distance is too small, water droplets will easily adhere to the first conductive member 12 and the separator 61, resulting in a short circuit. At the same time, if the distance is too small, it is not easy to clean the gap between the first conductive member 12 and the separator 61. Therefore, within the above-mentioned thickness range, it can be ensured that the separator 61 is not easy to deform during the processing, and it is also convenient to clean the inside of the insertion cavity 111.

[0042] In some embodiments, Figure 7 , Fig. 9 As shown, the overall structure of the partition piece 600 is symmetrical only in one direction, and the partition groove 212 corresponds to the partition piece 600. In practical applications, the first terminal 100 and the second terminal 200 need to be plugged in at a relatively fixed angle to ensure that the corresponding first conductive member 12 and the second conductive member 22 can be correctly plugged in. By setting the partition piece 600 to be a structure symmetrical only in one direction, the first terminal 100 and the second terminal 200 can have only one fixed plugging corresponding angle during the plugging process, so that the first terminal 100 and the second terminal 200 can be correctly plugged in.

[0043] It is understandable that the partition member 600 may also be configured as a completely asymmetric structure, and the completely asymmetric structure may also ensure that the first terminal 100 and the second terminal 200 have only one fixed relative plug-in angle.

[0044] In some embodiments, Figure 4As shown, along the protruding direction of the first conductive member 12, the free end of the above-mentioned partition 61 protrudes beyond the free end of the first conductive member 12. Such a design can prevent the partition 61 from contacting the object before the first conductive member 12 when the first terminal 100 contacts other objects, thereby protecting the first conductive member 12, avoiding damage to the first conductive body, and avoiding a short circuit caused by contact between the first conductive body and external conductive materials.

[0045] In some embodiments, Figure 4 , Figure 5 , Figure 6 As shown, the waterproof cable provided by the present application also includes two sealing rings 300, which are made of rubber or silicone material. Two sealing grooves 211 are opened on the side of the plug-in end of the second terminal 200. The sealing ring 300 is sleeved and fitted on the sealing groove 211 of the second terminal 200. When the second terminal 200 is inserted into the insertion cavity 111 of the first terminal 100, the sealing ring 300 is tightly fitted against the side wall of the insertion cavity 111 to achieve the purpose of multi-level sealing along the radial direction of the first terminal 100 or the second terminal 200, which can effectively prevent external liquid and gas from entering the insertion cavity 111 to cause a short circuit or signal interference between the first conductive member 12 and the second conductive member 22.

[0046] It is understandable that the number of the sealing ring 300 and the sealing groove 211 can be multiple, and this application does not impose any limitation on this.

[0047] In some embodiments, Figure 4 , Figure 5 , Figure 6 As shown, the waterproof wire provided by the present application also includes a sleeve 400, which is detachably connected to the first terminal 100 and the second terminal 200 respectively. After the first terminal 100 and the second terminal 200 are plugged into each other, the sleeve 400 can fix the first terminal 100 and the second terminal 200 from the outside to prevent the first terminal 100 and the second terminal 200 from loosening, and the sleeve 400 completely covers the connection between the first terminal 100 and the second terminal 200, and can also play a good physical protection role for the connection between the first terminal 100 and the second terminal 200. Taken together, the connection between the first terminal 100 and the second terminal 200 can be made more stable and secure.

[0048] Specifically, Figure 4 , Figure 5As shown, a thread groove 41 is provided on the inner side surface of the sleeve 400, and correspondingly, a threaded portion 13 is provided on the outer peripheral surface of the first terminal 100, and an abutment portion 23 is provided on the outer peripheral surface of the second terminal 200. In actual operation, the sleeve 400 is inserted from the end of the second terminal 200 away from the first terminal 100, and the sleeve 400 is moved so that the inner side of the sleeve 400 abuts against the side of the abutment portion 23 away from the threaded portion 13, and then the sleeve 400 is rotated so that the thread groove 41 of the sleeve 400 cooperates with the threaded portion 13 on the outer side of the second terminal 200, so that the sleeve 400 is threadedly connected to the first terminal 100, thereby fixing the first terminal 100 and the second terminal 200 to each other. The threaded connection method has a simple structure, is easy to disassemble and assemble, and the connection is also very firm and stable, thereby making the connection between the first terminal 100 and the second terminal 200 more firm and stable.

[0049] In some embodiments, Figure 4 As shown, the maximum outer diameter of the second terminal 200 is less than 15 mm. In actual applications, the waterproof line of the present application is usually used in the installation pipeline of the water purifier. Since the size of the faucet connection hole of the household sink is basically fixed, in order to adapt to this size, the diameter of the faucet bottom passing through the sink is limited. Therefore, in order to better adapt, the maximum side of the outer diameter of the female terminal is less than 15 mm, which is convenient for passing through the connecting pipe inside the faucet of the water purifier when connecting.

[0050] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
