[0006] As a preferred technical solution of the present invention, the bottom end of the water-absorbing cotton ring is tightly fitted with the top end of the expansion ring.

[0007] As a preferred technical solution of the present invention, second wire inlet grooves are opened on both sides of the inner wall of the base, and the inner walls of the first wire inlet groove and the inner walls of the second wire inlet groove are fixedly connected with arc-shaped absorbent cotton.

[0008] As a preferred technical solution of the present invention, an arc-shaped expansion strip is provided on one side of the arc-shaped water-absorbing cotton, and a plurality of the arc-shaped expansion strips are respectively fixedly arranged on the inner wall of the first wire feed groove and the inner wall of the second wire feed groove.

[0009] As a preferred technical solution of the present invention, an insert block is fixedly connected to the middle of the inner wall of the cover, and a slot is opened in the middle of the inner wall of the base, and the size of the insert block matches the slot.

[0010] As a preferred technical solution of the present invention, a through hole is opened in the middle of the cover body, and the screw hole corresponds to the position of the through hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model changes the traditional one-piece structure into a split and detachable design by providing a detachable base and cover, which makes it convenient to clearly see the specific internal conditions and positions during wiring operations, so that wiring can be more accurate. After the wiring debugging is completed, the base and the cover are connected and combined, which greatly reduces the operation time and difficulty.

[0013] 2. The utility model has absorbent cotton rings, expansion rings, arc-shaped absorbent cotton and arc-shaped expansion strips placed inside the outlet trough, the first inlet trough and the second inlet trough, so as to absorb moisture that is about to penetrate into the interior of the trough, and prevent the smooth inner wall of the trough from allowing moisture to flow directly. After continuously absorbing moisture, the expansion ring and arc-shaped expansion strip on one side are triggered to expand, so that when the amount of water is large, the trough can be blocked to prevent moisture from entering. At the same time, multiple heat conduction plates inserted in the narrow groove can transfer the heat generated at the internal wiring to the outside, thereby increasing the heat dissipation capacity. In combination with temperature-sensitive ink, when the internal temperature rises abnormally, the color change can be used to remind the operator that technical maintenance is required.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3 , the utility model provides a technical solution for bending plug:

[0020] Example 1:

[0021] according to Figure 1 、 Figure 2 and Figure 3 As shown, a bending plug includes a base 1, a wire outlet groove 3 is opened at the top of the base 1, a cover body 2 is snap-connected at the bottom end of the base 1, a first wire inlet groove 6 is opened on both sides of the inner wall of the cover body 2, and a screw hole 11 is opened in the middle of the inner wall of the base 1.

[0022] An insert 15 is fixedly connected to the middle of the inner wall of the cover body 2, and a slot 12 is opened in the middle of the inner wall of the base 1. The size of the insert 15 matches the slot 12. When the base 1 and the cover body 2 are connected, the positioning installation is first achieved by means of the connection between the insert 15 and the slot 12. A through hole 9 is opened in the middle of the cover body 2, and the screw hole 11 corresponds to the position of the through hole 9.

[0023] During specific use, the utility model provides a bending plug. The operator can first separate the base 1 and the cover body 2. Inside the base 1, the wires are brought in through the two second wire inlet grooves 10 for wiring operations, and the wires are taken out through the wire outlet grooves 3 on the base 1. In this way, the incoming wire direction, the outgoing wire direction and the specific position can be clearly seen. After the specific adjustment of the connected wires is completed, the cover body 2 is placed on the base 1, and the plug block 15 is docked and inserted into the slot 12. Then, with the help of screws, first pass through the through hole 9 and enter the screw hole 11 to realize threaded connection. In this way, the cover body 2 and the base 1 can be installed and connected, and the bent wiring point is enclosed inside.

[0024] Example 2:

[0025] Based on the first embodiment, Figure 1 and Figure 2 As shown, a water-absorbing cotton ring 4 is fixedly connected to the top of the inner wall of the wire outlet groove 3, an expansion ring 5 is fixedly connected to the middle of the inner wall of the wire outlet groove 3, and a plurality of narrow grooves 13 are opened on both sides of the middle of the cover body 2. The interiors of the plurality of narrow grooves 13 are vertically interspersed with heat conducting plates 14, and the surface of the heat conducting plates 14 is sprayed with temperature-sensitive ink. Thermochromic ink is an ink that changes color with changes in temperature. The basic colors are bright red and rose red, and the color can change with the rise and fall of temperature. Taking 31°C red as an example, the color change form is colorless above 31°C and red below 31°C.

[0026] The bottom end of the water-absorbent cotton ring 4 fits tightly with the top end of the expansion ring 5. A second wire feed groove 10 is opened on both sides of the inner wall of the base 1. The inner wall of the first wire feed groove 6 and the inner wall of the second wire feed groove 10 are fixedly connected with arc-shaped water-absorbent cotton 7. An arc-shaped expansion strip 8 is provided on one side of the arc-shaped water-absorbent cotton 7. The arc-shaped expansion strip 8 and the expansion ring 5 are made of water-swelling rubber. Multiple arc-shaped expansion strips 8 are fixedly arranged on the inner wall of the first wire feed groove 6 and the inner wall of the second wire feed groove 10, respectively.

[0027] During specific use, the utility model provides a bent plug. In subsequent use, when water enters from the outlet groove 3, the first inlet groove 6 and the second inlet groove 10, it will first be absorbed and stored by the absorbent cotton ring 4 or the arc-shaped absorbent cotton 7 to avoid flowing directly into the plug along the smooth inner wall of the groove. After the absorbent cotton absorbs water, if the water continues to increase, the absorbent cotton will be soaked, so that the expansion ring 5 or the arc-shaped expansion strip 8 that fits closely with it will expand when it encounters water, completely sealing the groove and the wiring to prevent water from entering the interior. During long-term use, the internal wiring parts will heat up, and the generated heat will be conducted out through multiple heat conduction plates 14 to enhance heat dissipation. At the same time, when the internal temperature rises abnormally, the heat conduction plate 14 will be heated, so that the temperature-sensitive ink on its surface will change color after reaching the threshold. Therefore, by observing the color of the heat conduction plate 14 exposed to the outside, it can be judged whether abnormal temperature rise has occurred inside at this time, and whether it needs to be opened for inspection and other operations for timely maintenance.
