[0019] Example 1

[0020] like Figures 1 to 4The cable connector for an electric control box shown in the figure comprises a first connecting tube 1 located on the left and a second connecting tube 2 located on the right. A slot 3 is extended on the right side of the first connecting tube 1. A sleeve 4 is slidably arranged on the left side of the second connecting tube 2. A plurality of fan-shaped clips 5 are intermittently arranged on the right side of the sleeve 4. A rubber block 6 is arranged on the right side of the fan-shaped clip 5. A guide ring 7 is arranged in the second connecting tube 2. An electric connection component 8 is connected between the slot 3 and the second connecting tube 2. The electric connection component 8 is divided into a central axis 801, a pin, a shielding sleeve 803, a cable slot 804 and a jack 805. The outer diameter of the slot 3 is the same as that of the second connecting tube 2. The inner hole diameters of the connecting tube 2 are consistent; the guide ring 7 is inclined and is located on the right side of the sleeve 4; a suction cup 9 is provided on the right side of the first connecting tube 1, and an adsorption plane 10 is provided on the left side of the second connecting tube 2; a pin is connected to the inner wall of the slot 3 through the central axis 801, and a shielding sleeve 803 is installed on the left side of the second connecting tube 2, a cable slot 804 is provided on the inner side of the shielding sleeve 803, and a plurality of sockets 805 are provided in the cable slot 804; the number of pins is the same as that of sockets 805, and they are plugged in and matched; a cover 11 is screwed on the outer side of the first connecting tube 1 and the second connecting tube 2, and a connecting hole 12 is provided on the cover 11.

[0021] The utility model installs a connecting tube at the cable connection and sets the outer side shape of the connecting tube to an arc shape, thereby preliminarily isolating the water vapor and moisture generated outdoors; further sets a suction cup 9 and an adsorption plane 10 at the connection of the two connecting tubes, so that the suction cup 9 is firmly adsorbed on the adsorption plane 10 when the cables are connected, thereby preventing water vapor from penetrating through the connection gap, thereby further enhancing the moisture-proof protection effect; finally, a gatherable fan-shaped clamp 5 is set in the second connecting tube 2, and when the two cables are connected, the fan-shaped clamp 5 is pushed to complete the gathering, driving the rubber block 6 thereon to clamp the cable, thereby achieving a deeper level of sealing and moisture-proof treatment for the cable; after the above-mentioned multi-level moisture-proof protection treatment, the aging degree of the cable is effectively slowed down, thereby ensuring the safe, reliable and efficient operation of the control box.

[0022] Example 2

[0023] like Figures 1 to 4The cable connector for the control box shown in the figure includes two connecting tubes, namely, a first connecting tube 1 located on the left and a second connecting tube 2 located on the right. The connecting tubes are made of waterproof material, and the left and right ends of the cable can be connected to the first connecting tube 1 and the second connecting tube 2 respectively. Then, the two cables that need to be installed together can be connected by plugging the adjacent first connecting tube 1 and the second connecting tube 2. The outer sides of the two connecting tubes are connected with a cover 11 through a thread, that is, the cover 11 can seal the left and right edges of the cable connection. At the same time, a through hole 12 similar to the size of the cable is opened on the cover 11 for pulling out excess cables. In order to prevent water vapor from adhering to the first connecting tube 1 and the second connecting tube 2, the shape of the cover 11 is specially set to a semicircular arc, so that water vapor can drip to both sides along the cover 11. Therefore, a rubber ring can be installed at the through hole 12 to achieve the closure of the internal space of the cable connector after installation, completing the preliminary waterproof preparation.

[0024] A slot 3 is extended on the right side of the first connecting tube 1. The outer hole diameter of the slot 3 is similar to the inner hole diameter of the second connecting tube 2. The operator can then hold the first connecting tube 1 and move it to the right, thereby driving the slot 3 to insert to the right into the second connecting tube 2, thereby completing a tight combination of the two and sealing the connection to prevent it from being in contact with the outside air for too long, which would aggravate aging.

[0025] Example 3

[0026] like Figures 1 to 4 The cable connector for the control box shown in the figure also easily realizes the electrical connection of two cables by connecting the power connection component 8 between the slot 3 and the second connecting tube 2. The power connection component 8 includes a central axis 801, a pin, a shielding sleeve 803, a cable slot 804 and a jack 805. The inner wall of the slot 3 is connected with a pin through the central axis 801, and the pin is located at the end of the cable; at the same time, a shielding sleeve 803 is installed in the second connecting tube 2, and the shielding sleeve 803 can prevent the cable from receiving external electromagnetic interference. The outer hole diameter of the shielding sleeve 803 is consistent with the inner hole diameter of the slot 3, and then when the slot 3 moves to the right and is inserted into the second connecting tube 2, the shielding sleeve 803 can be inserted into the slot 3 tightly to prevent the internal electrical connection position from being wet. A cable slot 804 is provided in the shielding sleeve 803, and a plurality of sockets 805 are opened in the cable slot 804. The number of sockets 805 is the same as the number of pins. Then the first connecting tube 1 drives the upper parts thereof. For example, when the pin moves to the right, the pin and the socket 805 can be plugged in while the first connecting tube 1 and the second connecting tube 2 are engaged. Then, electrical connection can be achieved after the cable is powered on.

[0027] Furthermore, in order to prevent moisture from seeping into the gap between the first connecting tube 1 and the second connecting tube 2, a suction cup 9 is provided on the right side of the first connecting tube 1, and a corresponding adsorption platform is provided on the left side of the second connecting tube 2. The adsorption platform can be made of a material with strong adsorption force when encountering water, such as plastic or ceramic. Therefore, when the first connecting tube 1 and the second connecting tube 2 are plugged in, the suction cup 9 can be driven to move to the right and contact the adsorption platform, gradually expelling the internal air, strengthening the connection between the two, and providing overflow protection for the gap between the first connecting tube 1 and the second connecting tube 2.

[0028] Example 4

[0029] like Figures 1 to 4 The cable connector for the control box shown is also provided with a clamping assembly for clamping and sealing one end of the cable, so as to achieve further moisture-proof and slow down the aging of the cable. A sleeve 4 is slidably provided on the left side of the second connecting tube 2. The sleeve 4 is specifically configured as hard rubber, and the inner hole diameter is equal to the outer diameter of the shielding sleeve 803. When the first connecting tube 1 and the second connecting tube 2 are not connected, the sleeve 4 can drive the shielding sleeve 803 to be fixed on the left side of the second connecting tube 2 for plugging; and after plugging, the slot 3 will replace the sleeve 4 and continue to fix the shielding sleeve 803 on the second connecting tube 2. A plurality of fan-shaped clips 5 are intermittently provided on the right side of the sleeve 4, and a rubber block 6 is provided on the right side of the fan-shaped clip 5. When the sleeve 4 is squeezed or slightly rotated, the fan-shaped clip 5 will be driven to swing inward, thereby driving the rubber block 6 to gather inward to clamp the cable, so as to achieve further sealing and moisture-proof treatment for the cable.

[0030] Correspondingly, a guide ring 7 is provided in the second connecting tube 2, at a position on the right side of the abutment sleeve 4. The guide ring 7 is tilted inward from left to right. Then, when the slot 3 moves to the right, driving the pin to be plugged into the socket 805 and the first connecting tube 1 to be plugged into the second connecting tube 2, the slot 3 will also push the abutment sleeve 4 to move to the right. At this time, the abutment sleeve 4 rotates in a small arc due to the inclined guiding force of the guide ring 7, driving the fan-shaped clamp 5 to gather inward, and then driving the rubber block 6 to merge and clamp the cable, thereby completing the moisture-proof sealing of the cable at the connected position.

[0031] 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.
