[0028] As shown in Figure 1 and 2 the light - equipped end structure of the electric tracing band in this embodiment includes a housing assembly 1, a lamp cover 2, a lamp group 3, and a terminal block assembly 4. The above - mentioned lamp cover 2 is hermetically installed at one end of the above - mentioned housing assembly 1. An inlet port is provided at the other end of the above - mentioned housing assembly 1. The above - mentioned lamp group 3 is installed at one end of the above - mentioned housing assembly 1 and is located inside the above - mentioned lamp cover 2. The above - mentioned terminal block assembly 4 is installed inside the above - mentioned housing assembly 1.

[0029] In the light - equipped end structure of the electric tracing band in this embodiment, the lamp cover 2 is injection - molded from polycarbonate plastic with high transparency and is assembled with the housing assembly 1 using a highly sealed structure, which can achieve good dust - proof and waterproof effects, prevent moisture and dust from entering the interior of the housing assembly 1, and ensure that the internal electrical components can operate well.

[0030] As a preferred implementation manner, the above - mentioned housing assembly 1 includes a first housing 11 and a second housing 12. The first housing 11 is a housing with one end open, and the inlet port is provided at the other end of the first housing 11. The second housing 12 is a housing with both ends open. One end of the second housing 12 is hermetically assembled with one end of the first housing 11. The above - mentioned lamp cover 2 is hermetically installed at the other end of the second housing 12. The above - mentioned terminal block assembly 4 is installed at the port at one end of the first housing 11, and the above - mentioned lamp group 3 is installed at the port at the other end of the second housing 12.

[0031] In the above embodiments, the housing assembly 1 is assembled by the first housing 11 and the second housing 12. A highly sealed structure is used for the assembly at the connection between the first housing 11 and the second housing 12. The lamp cover 2 part and the other end of the second housing 12 also adopt a highly sealed assembly structure. The design of the entire split combination structure facilitates the assembly of the internal terminal block assembly 4, as well as the assembly of the terminal block assembly 4 with the lamp group 3 and the incoming lines.

[0032] As a preferred embodiment, an engaging groove adapted to the terminal block assembly 4 is provided on the inner wall of one end port of the first housing 11, and the terminal block assembly 4 is installed in the engaging groove.

[0033] In the above embodiments, the engaging groove is preferably a square groove body, and the terminal block assembly 4 is generally square. Therefore, it can be relatively tightly embedded in the engaging groove to achieve good assembly of the two.

[0034] As a preferred embodiment, the first housing 11 is a cylindrical shell, and a first connecting ring seat 111 protrudes from the outer wall of one end thereof. The second housing 12 is a cylindrical shell, and a second connecting ring seat 121 protrudes outward from one end thereof. One end of the second housing 12 is sleeved outside one end of the first housing 11, and an annular first gasket 122 is clamped between the first connecting ring seat 111 and the second connecting ring seat 121. An annular first sealing ring 112 in contact with the inner wall surface of the second housing 12 is embedded in the outer wall of one end of the first housing 11. The first connecting ring seat 111 and the second connecting ring seat 121 are locked by a locking member 5.

[0035] In the above embodiments, after one end of the second housing 12 is inserted and sleeved outside one end of the first housing 11, double sealing is adopted between the two, so that the sealing performance at the connection between the two is better. At the same time, the stable assembly of the two can be achieved by using the locking member 5, and the waterproof and dustproof performance is better.

[0036] In this embodiment, a bent joint is formed at the connection between the second housing 12 and the first housing 11. Sealing is achieved by clamping the first gasket 122 at the part where the contact surface is larger at the joint. The outer peripheral joint of the two is sealed by the first sealing ring 112, achieving the purpose of high sealing performance at the connection between the two.

[0037] In this embodiment, both the first housing 11 and the second housing 12 are made of polyphenylene sulfide plastic (PPS), which has good high-temperature and ultraviolet resistance, is not easy to age and crack after long-term use, and has a long service life.

[0038] In this embodiment, the first gasket 122 is made of a rubber pad, and the first sealing ring 112 is a conventional O-ring.

[0039] As a preferred embodiment, the above-mentioned locking member 5 includes a lock ring 51. The inner wall of the lock ring 51 is provided with threads, and one end of its inner wall is provided with a first limiting ring 52. The above-mentioned first connecting ring seat 111 is a circular ring member, and its outer edge is provided with threads. The lock ring 51 is screwed onto the outside of the first connecting ring seat 111, and the inner wall surface of the first limiting ring 52 abuts against the end surface of the second connecting ring seat 121.

[0040] In the above-mentioned implementation scheme, the design of the locking member 5 is quite ingenious. By using the "hooking" fit formed between the first limiting ring 52 and the second connecting ring seat 121, when the locking member 5 is tightened, the first limiting ring 52 can apply pressure to the end surface of the second connecting ring seat 121, so that the second connecting ring seat 121 tightly abuts against the end of the first connecting ring seat 111, clamping the first gasket 122.

[0041] As a preferred embodiment, the outer edge of the other end of the above-mentioned second housing 12 is provided with a ring groove 123. One end of the lamp cover 2 is provided with an annular connecting notch 21. The inner wall of the connecting notch 21 is provided with threads. The outside of the other end of the second housing 12 is provided with threads. The connecting notch 21 is screwed onto the outside of the other end of the second housing 12. An annular second gasket 124 is clamped between the bottom of the ring groove 123 and the bottom wall of the connecting notch 21. An annular second sealing ring 211 that contacts the inner wall surface of one end of the lamp cover 2 is embedded in the wall surface of the ring groove 123.

[0042] In the above-mentioned implementation scheme, the other end of the second housing 12 is spirally connected to the connecting notch 21 at one end of the lamp cover 2, and a bent joint is formed at the joint. The sealing of the pressing surface between the two is realized through the second gasket 124, and the sealing between the outer peripheral joints of the two is realized through the second sealing ring 211, so as to achieve high sealing performance at the joint between the second housing 12 and one end of the lamp cover 2. More specifically, when the connecting notch 21 is screwed and tightened, the bottom wall of the connecting notch 21 will apply pressure to the bottom of the ring groove 123, thereby clamping the second gasket 124.

[0043] As a preferred embodiment, the above-mentioned lamp group 3 includes a lamp panel and chips arranged on one side of the lamp panel and LED lamp beads connected to the chips. The lamp panel is installed at the end of the other end of the above-mentioned second housing 12 by screws.

[0044] In the above-mentioned implementation scheme, the lamp panel is made of a glass fiber board, on which a circuit board and lamp beads are arranged. The lamp panel is a disc, and its edge is connected to the end of the other end of the second housing 12 by several screws, and the disassembly and assembly are relatively simple.

[0045] In this embodiment, the above-mentioned lamp cover 2 is a hemispherical cover body. The hemispherical cover body can make the diffusion range of light larger.

[0046] In this embodiment, a cable entry gland 6 is hermetically installed at the above cable entry port. The protection level of the cable entry gland 6 is IP66.

[0047] As a preferred embodiment, as Figure 3 shown, it further includes a mounting bracket 7. The above mounting bracket 7 is C-shaped, one end of which is connected to the other end of the above housing assembly 1, and a pipe clamp is provided at the other end of the above mounting bracket 7.

[0048] In the above embodiment, the design of the mounting bracket 7 facilitates the assembly of the entire structure on the pipeline. More specifically, one end of the mounting bracket 7 fits against the end of the other end of the housing assembly 1, and the other end of the mounting bracket 7 is provided with a V-shaped structure protruding towards its one end. This V-shaped structure just fits outside the arc-shaped surface of the pipeline. Hole positions are respectively opened on the two inclined surfaces of the V-shaped structure. A part of the clamp passes through the hole positions on the two inclined surfaces of the V-shaped structure to realize the assembly with the mounting bracket 7, and then the pipeline is tightened by the clamp, so that the mounting bracket 7 and the entire device can be firmly installed on the pipeline. Among them, the mounting bracket 7 is made of a stainless steel bracket.
