Description

Technical Field

[0001] This utility model relates to the technical field of power transmission system accessories, and in particular to a dry-type outgoing pole with protective effect. Background Technology

[0002] Dry-type cable outlets are typically used for connecting insulated conductors, aluminum stranded wire, aluminum-metal stranded wire, steel-cored aluminum stranded wire, and copper conductors in non-load-bearing positions. A typical structure includes a tube with a wiring channel at one end, and a crimping step extending from the other end, with mounting through holes on the crimping step for electrical connection to the equipment terminals. The side wall of the tube has positioning holes communicating with the wiring channel. After the conductor is inserted into the tube, it is tightened by screwing in positioning bolts into the positioning holes, thus achieving a continuous connection between the conductor and the equipment.

[0003] However, existing technologies still suffer from the problem of rainwater seepage at the connection point between the conductor and the outlet pole. Moisture infiltration can degrade the performance of the cable's internal insulation material, reducing insulation resistance and potentially leading to electrical accidents or even fires. Simultaneously, moisture can damage the cable's internal metal conductors, causing short circuits, open circuits, and other faults, which can damage electrical equipment. Furthermore, moisture degrades the cable's insulation and conductivity, reducing current transmission efficiency, increasing electricity costs, and shortening the lifespan of electrical equipment, resulting in economic losses.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Summary of the Invention

[0015] Beneficial effects:

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention achieves initial fixation of the wire by sequentially passing it through a clamping member and a tightening member, and placing it within the wiring through-hole, using a positioning bolt. As the clamping member and the connecting part become firmly connected, the spring force not only ensures a tight fit between the tightening member and the wire's insulation layer, preventing the penetration of external humid air, but also applies a continuous clamping force to the wire, achieving double fixation. This design effectively strengthens the connection strength between the wire and the rod. Furthermore, the cooperation between the O-ring seal and the tightening member further prevents the penetration of external humid air into the wiring through-hole. In addition, the connection between the clamping member and the connecting part can be completed without the need for tools. Therefore, this solution has the advantages of good sealing effect, high connection stability, and simple operation. Attached Figure Description
