Description
技术领域 technical field
本实用新型涉及一种接线鼻，具体涉及一种可防水、防油及防潮的接线鼻。 The utility model relates to a wiring nose, in particular to a waterproof, oil-proof and moisture-proof wiring nose.
背景技术 Background technique
目前的电缆终端接线鼻一般都没有防水结构，接线鼻与输电电缆终端连接后，再用相应的绝缘胶带对连接部位进行密封处理以防水渗入，费时费力。而且绝缘胶带的使用时间长了会出现老化现象，从而降低防水、防潮的效果，最后由于密封不良使得雨水或者潮气渗入而造成故障。 Current cable terminal lugs generally do not have a waterproof structure. After the lug is connected to the power transmission cable terminal, the corresponding insulating tape is used to seal the connection part to prevent water infiltration, which is time-consuming and labor-intensive. Moreover, if the insulating tape is used for a long time, aging will occur, thereby reducing the waterproof and moisture-proof effects, and finally due to poor sealing, rain or moisture will penetrate and cause failure.
