Description

Technical Field

[0001] The utility model relates to the field of street lamp cable docking devices, in particular to a deep - water cable docking device. Background Art

[0002] A street lamp cable docking device is a special device specifically used to connect street lamp cables in outdoor lighting systems such as public roads, streets, and parks. Usually, when connecting, the cable sheath at the cable connection point needs to be peeled off, and the cable connection is completed by crimping with a copper pipe (or aluminum pipe) or by winding the cable. Then, the connection is wrapped with an insulating sleeve or insulating tape, and a five - finger sleeve is used at the branch point and processed by heating and heat - shrinking. Under this installation method and usage requirements, the cable docking position and the docking device are long - term in the inspection well. The air humidity in the inspection well is high, and at the same time, it is affected by environmental factors such as corrosion by snow - melting agents. Different degrees of damage will occur at the cable joint, resulting in cable oxidation, which in turn increases the contact resistance at the cable joint, exacerbates the cable heating situation, and even causes accidents such as cable burning and cable leakage. And problems such as cable water ingress and difficult maintenance are likely to occur at the five - finger sleeve. Over time, safety problems such as electric leakage are likely to occur. And there is a lack of technical solutions in the existing cable wiring device field that can properly solve the above problems. Content of the Utility Model

[0024] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

The tower - type self - locking flange includes a flange tower 34 protruding from the outside of the base 21. The flange tower 34 is made of a flexible material such as rubber. The flange tower 34 is a multi - layer circular tower - type structure. The inner diameter of each layer of the circle corresponds to the outer diameter of the cable and is smaller than the outer diameter of the cable. During installation, the corresponding number of layers is cut off according to the cable size, so that while the cable can pass through the flange tower 34, the relative dimensional difference and the material characteristics of the flange tower 34 can be used to tightly enclose the flange tower 34 around the cable periphery to ensure the sealing effect. Preferably, a flange tightening groove 35 is provided inside the flange tower 34. The number of the flange tightening grooves 35 is multiple and is provided inside each circle. A flange tightening ring is provided in the flange tightening groove 35 to further increase the locking force and locking area of the flange and avoid leakage after filling with electronic sealant later.

[0029] The tower - type self - locking flange further includes a clamping plate 31. The flange tower 34 is provided on the clamping plate 31. A flange clamping groove 23 is provided on the base 21.

The side walls of the base 21 on both sides and at the bottom of the flange clamping groove 23 are clamped in the clamping grooves 32. By disassembling and replacing different tower - type self - locking flanges, the device can be reused or replaced in case of operation errors.

[0030] As Figure 2 andFigure 3 As shown, a first sealing protrusion 24 is provided along the upper edge of the base 21, and a second sealing protrusion 33 is provided along the upper edge of the clamping plate 31. When the clamping plate 31 is installed in the flange slot 23, the upper edges of the first sealing protrusion 24 and the second sealing protrusion 33 are flush. A top cover sealing groove 13 is provided inside the top cover 11, and a sealing ring is provided in the top cover sealing groove 13. When the top cover 11 is buckled on the base 21, the first sealing protrusion 24 and the second sealing protrusion 33 are in contact with and pressed against the sealing ring, thereby meeting the sealing requirements of the device.

[0031] As Figure 3 shown, a wiring module is provided inside the base 21. The wiring module includes a wiring base 41 and a wiring terminal. The wiring terminal is fixedly connected to the base 21 through the wiring base 41. Specifically, base mounting holes 42 are provided on the wiring base 41, and terminal mounting holes 52 are provided on the terminal base 51. The wiring base 41 is fixedly connected to the base 21 by bolts through the base mounting holes 42, and the terminal base 51 is fixedly connected to the wiring base 41 by bolts through the terminal mounting holes 52.

[0032] As Figures 5 to 8 shown, the wiring terminal includes a terminal base 51 and a compression bolt 53.

Through the above connection device, during the rotation of the compression bolt 53, the bottom surface of the pressure pad 55 is always in contact with the cable surface and does not rotate relatively, ensuring the reliability of the crimping. Preferably, the bottom surface of the pressure pad 55 is arc-shaped and the arc opening is downward, thereby increasing the contact area between the pressure pad 55 and the cable and ensuring the carrying capacity of the cable connection.

[0033] Preferably, a plurality of compression bolts 53 are provided on the terminal base 51, and the plurality of compression bolts 53 are distributed along the length direction of the cable, thereby improving the pressing effect on the cable, increasing the pressing area, and ensuring the quality of the cable connection.
