[0005] In another preferred embodiment, one end of the joint body is threadedly connected to one end of the intermediate locking nut.
[0006] In another preferred embodiment, the inner wall of one end of the joint body is provided with a first internal thread, and the outer wall of one end of the intermediate locking nut is provided with a first external thread, and the first internal thread matches the first external thread.
[0007] In another preferred embodiment, the other end of the threading tube body is threadedly connected to one end of the cable locking nut.
[0008] In another preferred embodiment, the inner wall of the other end of the threading tube body is provided with a second internal thread, and the outer wall of one end of the cable locking nut is provided with a second external thread, and the second internal thread matches the second external thread.
[0009] In another preferred embodiment, both the first external thread and the second external thread are G1 / 2 pipe threads.
[0010] Due to the adoption of the above technical solution, the utility model has the following positive effects compared with the prior art: through the application of the utility model, a waterproof cable gland is provided, the connector body adopts an L-shaped setting, the cable inlet is from bottom to top, and rainwater is prevented from accumulating at the gland inlet and penetrating into the interior of the equipment, thereby ensuring the sealing effect.

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0014] like Figure 1 As shown, a waterproof cable gland of a preferred embodiment is shown, comprising:
[0015] A connector body 1, a sealing ring 2, an intermediate locking nut 3, a clamping ring 4, a wire threading tube body 5 and a cable locking nut 6. The cross-section of the connector body 1 is set in an "L" shape. One end of the intermediate locking nut 3 is installed at one end of the connector body 1, and a sealing ring 2 is provided at one end of the intermediate locking nut 3. The other end of the intermediate locking nut 3 is installed at one end of the wire threading tube body 5. The clamping ring 4 is installed in the wire threading tube body 5, and one end of the clamping ring 4 is clamped against the other end of the intermediate locking nut 3. One end of the cable locking nut 6 is installed at the other end of the wire threading tube body 5, and one end of the cable locking nut 6 is clamped against the other end of the clamping ring 4.
[0016] During actual use, when the connector body 1 is installed, the entrance at one end of it is facing downward to ensure that the cable enters from below. The threading tube body 5 is connected through the middle locking nut 3 and the sealing ring 2. The clamping ring 4 is installed in the threading tube body 5 to clamp the cable. The cable locking nut 6 is responsible for pressing the clamping ring 4 to ensure sealing.
[0017] Further, as a preferred embodiment, one end of the joint body 1 is threadedly connected to one end of the intermediate locking nut 3 .
