The utility model relates to a self-sealing rectangular connector, which comprises an insulating base, a public connector and a sealing gasket. The rectangular inner wall of the insulating base is provided with a convex platform at the waist, and a groove is arranged at the connection between the convex platform and the inner wall; on the one side of the insulating base and the shell of the electrical component, there are six guiding positioning grooves; and the public plug-in is installed on the convex platform between the rectangular inner wall of the insulating base, and there is a sealing cushion between the two. The insulating base is mounted on the shell of the electrical component, and there is a sealing pad B matching with six guiding positioning grooves between the two. The common plug-in includes a common plug insulating shell, a conductive common plug, a grounding component and an O-ring. The conductive common pin and grounding component are arranged on the dies of the insulating shell of the common pin, and the gap between them is eliminated by forming an integral part with the conductive common pin during injection. It ensures that the rectangular connector has sealing and waterproof performance when it is not equipped with waterproof shell, and improves the reliability of mechanical and electrical products.

一种自密封矩形接插件
本专利技术涉及工业接插件,尤其涉及自密封矩形重载接插件。
技术介绍
接插件也叫连接器,它是实现电路器件、部件或组件之间可拆卸连接最基本的机械式电气连接器件。它由公、母插件及其附件组成并成套使用,其主要功能是传输信号和电流,并可控制所连电气的通或断。现有的矩形接插件,公插件中的公插针、接地组件与公插针绝缘壳,公插件与底座之间均存在间隙。为防尘、防水,公母接插件对插后,需通过配备防水外壳阻止外部水蒸气进入电气腔。由于工况原因,有些机电设备常年暴露在风吹日晒、高温或含有腐蚀性环境,导致矩形接插件防水外壳锁扣松动,外壳密封垫风化;此外用户现场开盖维修后也经常忘记扣上防水外壳锁扣,这些情况导致矩形公插件直接暴露在空气中。出现上述情况,雨水或水蒸气从公插件进入机电设备电气腔内,引起电气故障,导致设备停机,甚至烧毁电气部件,引起经济损失和安全事故。因此特别需要一种自密封的矩形接插件来解决上述问题,增加电气产品的可靠性。
