Description

一种发热电缆一体化密封隐式连接结构 技术领域 本发明涉及一种电缆连接结构， 尤其涉及一种发热电缆一体化密封隐 式连接结构。 背景技术 目前， 发热电缆一体式隐式连接结构多为机械式驳接发热体与冷引线 的结构， 用连接器驳接发热体与冷引线， 驳接部分外套用带胶的热收缩管， 避免发热电缆断路、 短路现象。 但存在着不足的地方： 由于热收缩管的材 料和发热电缆以及冷引线的材料不一致， 相熔性差， 往往会在热收缩管与 发热电缆和冷引线间产生间隙。 因为发热电缆是敷设在地底下的， 由于受 水气和潮气的影响， 隐式连接处往往会因此失去保护功能， 造成漏电现象。 发明内容 本发明的目的在于提供一种能够彻底防水、 防漏电且保护性能好的发 热电缆一体化密封隐式连接结构。 本发明的目的是通过以下技术方案来实现的： 一种发热电缆一体化密封隐式连接结构， 包括发热电缆、 冷引线和连 接件， 所述的连接件驳接发热电缆和冷引线， 在驳接处的整个外围设置一 个连接套管， 连接套管一端位于发热电缆上， 连接套管的另一端位于冷引 线上， 所述连接套管的两端填封灌封胶， 构成封闭的阻水层。 所述的连接套管为硅胶管、 PE管、 PVC管或 PP管。 所述的灌封胶为液体硅胶、 环氧树脂胶或 PVC树脂胶。 为进一步提髙发热电缆一体化密封隐式连接结构的密封性能， 在所述 的连接套管外围设置一个热收缩管， 热收缩管一端位于发热电缆上， 热收 縮管的另一端位于冷引线上， 所述热收缩管的两端与发热电缆和冷引线经 热收缩密封连接。 增强密封隐式连接结构防水、 稳定的耐电压击穿强度及' 较高的可靠性能。 · 所述的热收缩管为交联聚乙烯热收缩管。 本发明与现有技术相比具有以下有益效果： 用软硬质连接套管套住发 热电缆和冷引线驳接处， 并在软硬质连接套管两端填封灌封胶， 形成封闭 的阻水层， 不仅使发热电缆和冷引线牢固地连接在一起， 而且阻挡了水和 水气的潜入， 确保发热电缆在使用过程中具有防水、 稳定的耐电压击穿强 度及较高的可靠性。 附图说明 图 1是本发明的结构示意图。 具体实施方式 图 1所述的发热电缆一体化密封隐式连接结构为本发明的一个实施例， 它包括发热电缆 1 和冷引线 2， 通过机械连接器用铜带 /铜管连接件 6把二 者驳接起来， 连接套管 3套在整个驳接处的外围， 连接套管 3—端位于发 热电缆 1上， 连接套管 3的另一端位于冷引线 2上， 连接套管 3可以采用 硅胶管、 PE管、 PVC管或 PP管。 在连接套管 3的两端用填充机灌注液体 硅胶、 PVC树脂胶或环氧树脂胶， 形成封闭的阻水层 4， 使发热电缆和冷 引线牢固地连接在一起， 并且可以彻底阻挡了水和水气的渗入。 另外， 连接套管 3外围再设置一个交联聚乙烯热收缩管 5， 热收缩管 5 一端位于发热电缆 1上，热收缩管 5的另一端位于冷引线 2上，热收缩管 5 的两端与发热电缆 1和冷引线 2用热风枪加热使其收缩紧密， 达到密封连 接。
使用过程中当热收縮管两端密封不好产生间隙时，水和水气会顺着发热 电缆和冷引线进入隐式驳接部位， 但由于驳接部位连接套管的两端注射灌 封胶， 使其与发热电缆和冷引线牢固粘在一起， 形阻挡水和水气的渗入， 确保加热电缆在使用过程中具有防水、稳定的耐电压击穿强度及高可靠性。
