Among them, ceramic tubes play an important role in some circuit connections. When connecting some circuits, ceramic tubes are used to sleeve on the connection ends of the circuits to prevent the connection points from loosening due to external force or vibration, thereby ensuring the connectivity of the circuit.

[0003] In the prior art, some ceramic tubes have a tube body composed of two groups of semicircular pieces, which makes it convenient to wrap it around the outer wall of the line connection end. When the ceramic tubes are spliced and installed, they are generally fixed together by colloid. The installation process is quick, and the edges of the splices can be filled to ensure the sealing of the ceramic tubes. However, when splicing, the colloid is generally applied manually on the splicing surface, and the amount of colloid applied cannot be accurately controlled. This may cause excessive addition of colloid and overflow, and accidentally stick to the user's skin, causing damage to the user. Therefore, a highly sealed ceramic tube is proposed to solve the above problems. Utility Model Content

[0029] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a high-sealing ceramic tube, comprising an upper cover 1, the lower surface of the upper cover 1 contacts the lower cover 2, and the upper cover 1 and the lower cover 2 are combined to form a ceramic tube to fix the connecting end of the wire body, ensuring the stability of the wire body, a positioning component is provided on the lower surface of the upper cover 1, and an anti-overflow component is provided in the middle of the upper surface of the lower cover 2. An anti-overflow hole 8 is opened at the left end of the upper surface of the lower cover 2, and the colloid flowing to the outside will be intercepted by the anti-overflow hole 8 to prevent the colloid from overflowing from between the upper cover 1 and the lower cover 2. The positioning component includes a positioning block 72 for positioning the combination between the upper cover 1 and the lower cover 2, and the positioning block 72 is fixedly connected to the lower surface of the right end of the upper cover 1, and a positioning groove 71 is opened on the upper surface of the lower cover 2 near the right side of the anti-overflow hole 8. When the upper cover 1 and the lower cover 2 are combined, The positioning block 72 is inserted into the inner wall of the positioning groove 71 to ensure the accuracy of positioning between the upper cover 1 and the lower cover 2. In addition, before merging, a certain amount of glue can be added to the inside of the positioning groove 71 to ensure the stability of the connection between the upper cover 1 and the lower cover 2. The lower surface of the positioning block 72 contacts the inner wall of the positioning groove 71. An arc-shaped through groove 5 is provided on the upper surface of the lower cover 2 near the right side of the positioning groove 71. The colloid squeezed out from the inside of the positioning groove 71 and flowing toward the wire body will enter the inside of the arc-shaped through groove 5 to prevent the colloid from directly entering between the wire body and the lower cover 2, and flowing out through the two ends of the lower cover 2. The anti-overflow hole 8 is connected to the arc-shaped through groove 5. A leakage hole 2 6 is provided in the middle of the upper surface of the lower cover 2. The colloid entering the inner wall of the arc-shaped through groove 5 will flow to the outer wall of the wire body through the leakage hole 2 6, thereby ensuring the sealing and stability of the connection between the wire body and the lower cover 2.

[0030] Reference Figure 1- Figure 2 The overflow prevention component includes an arc-shaped plate 31 to prevent the colloid from overflowing from both ends of the lower cover 2. The arc-shaped plate 31 is fixedly connected to the middle part of the upper surface of the lower cover 2. The upper surface of the arc-shaped plate 31 is provided with a leakage hole 32 to ensure that the colloid can flow smoothly to the outer wall of the wire body. The leakage hole 32 is connected to the leakage hole 2 6.

[0031] Reference Figure 1 、 Figure 3 A sealing groove 74 is provided on the left side of the inner wall of the positioning groove 71. When the upper cover 1 and the lower cover 2 are combined together, the sealing strip 73 will be inserted into the inner wall of the sealing groove 74 to improve the sealing between the upper cover 1 and the lower cover 2. A sealing strip 73 is fixedly connected to the left surface of the positioning block 72. The sealing strip 73 contacts the inner wall of the sealing groove 74. The left surface of the sealing strip 73 is set to an arc surface. The sealing strip 73 is set to a rubber material. The arc surface of the sealing strip 73 and its own rubber elasticity ensure that the sealing strip 73 can be smoothly inserted into the inner wall of the sealing groove 74 when the upper cover 1 and the lower cover 2 are combined together.

[0032] Reference Figure 1 - Figure 2 , there are multiple groups of arc-shaped through grooves 5 and leakage holes 6, and the multiple groups of arc-shaped through grooves 5 and leakage holes 6 are arranged in the middle of the lower surface of the upper cover 1. A through hole 4 is opened on the upper surface of the upper cover 1. The colloid can be added between the wire body and the ceramic tube for a secondary time through the through hole 4 to improve the sealing and stability of the connection. The through hole 4 is connected to the multiple groups of arc-shaped through grooves 5. There are multiple groups of positioning components, and the multiple groups of positioning components are symmetrically arranged with the center line of the upper cover 1 as the symmetry axis. Multiple groups of positioning components are set to ensure the accuracy of positioning between the upper cover 1 and the lower cover 2.

[0033] Working principle: First, when assembling the ceramic tube, the positioning block 72 on the lower surface of the upper cover 1 should be aligned with the positioning groove 71 opened on the upper surface of the lower cover 2. Before merging, a certain amount of glue can be added inside the positioning groove 71 to ensure the stability of the connection. In addition, the sealing strip 73 fixed on the left surface of the positioning block 72 will be deformed in this process and smoothly sealed in the sealing groove 74, ensuring the accuracy of positioning between the upper cover 1 and the lower cover 2 and the initial sealing.

[0034] When using colloid to adhere the upper cover 1 and the lower cover 2, if the colloid is added in excess, the colloid flowing to the outside will be intercepted by the anti-overflow hole 8 at the left end of the upper surface of the lower cover 2, preventing the colloid from overflowing from between the upper cover 1 and the lower cover 2. The colloid squeezed out from the inside of the positioning groove 71 and flowing toward the wire body will enter the inside of the arc-shaped through groove 5, preventing the colloid from directly entering between the wire body and the lower cover 2 and flowing out from both ends of the lower cover 2. The colloid entering the inner wall of the arc-shaped through groove 5 will flow to the outer wall of the wire body through the leakage hole 2 6 in the middle of the upper surface of the lower cover 2, ensuring the sealing and stability of the connection between the wire body and the lower cover 2.

[0035] In addition, the arc plate 31 in the middle of the upper surface of the lower cover 2 can prevent the colloid from overflowing from both ends of the lower cover 2. The leakage hole 1 32 on the upper surface of the arc plate 31 is connected to the leakage hole 2 6, ensuring that the colloid can flow smoothly to the outer wall of the wire body.

[0036] During the secondary glue injection, glue can be added through the through hole 4. The added glue will flow along the multiple groups of arc grooves 5 and the multiple groups of leakage holes 6 to between the wire body and the ceramic tube, thereby improving the stability and sealing of the connection.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
