Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering, specifically to a low-voltage engineering pipeline connection device. Background Technology

[0002] Low-voltage electrical engineering cabling refers to the conduit system used for laying cables in low-voltage systems, mainly consisting of indoor and outdoor parts. The indoor part typically comprises low-voltage conduits (such as PVC pipes or galvanized steel pipes), low-voltage cable trays (such as galvanized cable trays or PVC cable trays), and low-voltage manholes; while the outdoor part mainly includes low-voltage manholes (such as manholes or handholes) and low-voltage cable conduits. These conduit systems together form the foundation of low-voltage electrical engineering, ensuring smooth cable laying and stable system operation.

[0003] When connecting cables in low-voltage electrical engineering, the wiring points are simply separated by wrapping them with insulating tape. This results in poor stability of the cable connections, and the messy cable interfaces can affect the arrangement of other cables, which is a drawback. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 1-3As shown, the present invention proposes a low-voltage engineering pipeline connection device, which includes a symmetrically arranged traction frame 1, and a clamping ring 2 is provided in the inner layer of the traction frame 1.

[0025] The clamping mechanism includes an inclined plate 31 formed at the corner of the traction frame 1, and a bolt 32 is installed in the screw hole between the inclined plate 31 and the clamping ring 2. The bolt 32 has a bolt cap 33 and a rubber pad 34 formed at both ends.

[0026] A cable 4 is pulled through the inside of the clamp 2, and a cable core 5 is provided at one end of the cable 4 that passes through the clamp 2.

[0027] A protective shell 6 is provided on the top of the traction frame 1, and the protective shell 6 is inserted between the traction frame 1 and the clamping ring 2 through a positioning member 7;

[0028] The wiring mechanism includes a rod frame 81 mounted on the top of the housing 6, a helical screw 82 mounted in the middle of the rod frame 81, guide rods 83 on both sides of the screw 82, a handle 84 connected to one end of the screw 82, and a pressure plate 85 that moves along the guide rod 83 is sleeved on the outside.

[0029] It should be noted that:

[0030] 1. The inclined plate 31 at the corner of the traction frame 1 is an inclined structure. The purpose is to pass through the bolt 32 on the inclined plate 31 at the corner. By the screwing of the bolt 32, the cable 4 inserted into the clamping ring 2 is initially clamped and limited.

[0031] 2. A clamping gap is left between the traction frame 1, the inclined plate 31 and the clamping ring 2. The clamping gap is adapted to the positioning part 7 at the bottom of the protective shell 6. The positioning part 7 is formed at the bottom of the protective shell 6. The protruding part of the positioning part 7 is embedded in the slots left in the two traction frames 1 to separate the inner and outer parts of the upper part of the cable core 5 of the traction frame 1.

[0032] In this embodiment, when it is necessary to connect the cable 4, the cable sheaths of the two cables 4 are first stripped to expose the cable core 5. The cable 4 is placed into the inner cavity of the clamping ring 2, and the bolt 32 is screwed according to the cable specifications. The outer wall of the cable 4 is initially clamped at the symmetrical corners, and then the upper cable core 5 is wound and connected.

[0033] Subsequently, the positioning part 7 at the bottom of the protective shell 6 is pressed into the clamping gap left between the traction frame 1, the inclined plate 31 and the clamping ring 2, leaving the cable core 5 connection part in the clamping area. At this time, the rotation of the screw 82 drives the pressure plate 85 to move downward along the guide rod 83. During the pressing process, the bottom of the pressure plate 85 is attached to the wound cable core 5 to prevent the cable core connection part from loosening, improve the installation stability, and the shell structure facilitates the sorting of complex wire harnesses, which is convenient for subsequent inspection and maintenance.

[0034] It is understandable that the cap 33 is located on the outside of the inclined plate 31, and the rubber pad 34 is located on the inside of the clamping ring 2. The purpose of setting the rubber pad 34 is to prevent the outer wall of the cable 4 from being compressed and damaged.

[0035] To further improve the insulation performance of the housing 6, the housing 6 is made entirely of rubber, and the pressure plate 85 moves linearly along the inner cavity of the housing 6.

[0036] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
