Description

屏蔽金属电缆防水连接器 Shielding metal cable waterproof connector

技术领域 FIELD

[0001] 本实用新型涉及电磁兼容屏蔽电缆夹紧连接头,具体涉及一种屏蔽金属电缆防水连接器。 [0001] The present disclosure relates to clamping EMC shielded cable connectors, in particular to a metal shield watertight cable connector.

背景技术 Background technique

[0002] 电缆屏蔽是指将外部的干扰信号通过电缆外部的金属屏蔽层吸收掉,防止对电缆内部的控制信号产生干扰。 [0002] refers to an external cable shield is absorbed by the interference signal outside the cable metal shield, to prevent interference to the control signals inside the cable. 或将电缆内部控制信号产生的干扰通过电缆外部的金属屏蔽层吸收掉,防止对外部产生干扰。 The internal cable control or interference signal generated by an external metal shield cable absorbed, to prevent interference to the outside.

[0003] 电磁兼容的屏蔽电缆连接头的作用就是要将电缆屏蔽层上的干扰信号通过金属体有效地传递到控制柜或设备母体上,通过接地传递到大地上而起到屏蔽作用。 [0003] EMC shielded cable operatively connected to the head is an interference signal on the cables will pass through a metal shield member to efficiently control cabinet or on the parent device is transmitted to the ground through the ground and shielding functions.

[0004] 目前国内市场上的电磁兼容的屏蔽电缆连接头大部分是通过在夹紧芯体上加置一个0型圈,电缆线去外皮后,要将屏蔽层导体反包在芯体外置的0型圈上,然后要用力将其置入金属接头栓体内,通过0型圈的弹性力来压紧屏蔽层导体与金属接头栓体接触,达到屏蔽要求。 [0004] It is EMC shielded cable connectors on the domestic market is mostly on the clamping core by adding an 0-ring is set, the cable to the skin, to shield the core conductor turnup external 0-ring, and then to force it into the metal body of the plug connector, by the elastic force of O-ring to compress the conductor shield layer and the metal connector plug contact for shielding requirements. 此种屏蔽接头体存在以下缺陷:1、只能在电缆端部的割断的屏蔽层上使用。 Such a shield connector body present the following disadvantages: 1, the shield only on the cut end of the cable. 2、芯体上0型圈与接头栓体之间间隙较小,包了屏蔽层的芯体很难塞入金属栓体内,或只能包入部分的屏蔽导体,影响达到最佳的屏蔽效果。 2, between the 0-ring over the core plug body and the joint gap is small, the package is difficult to shield the core metal bolt inserted into the body, or only a portion of the shield conductor package, the influence of the best shielding effect . 3、大规格的粗电缆线相应的屏蔽层导体也粗些,相对较硬了,反折过来也相对困难,不容易快捷地将其反包在芯体上,不便于操作者安装。 3, the shield conductor corresponding large sizes also some rough thick cable, the relatively hard, relatively difficult to fold over, it is not easy to quickly turnup on the core, is not easy to install the operator.

[0005] 另外现有进口电磁兼容的屏蔽接头是屏蔽卡环,但接头芯体与接头栓体之间的配合不能止转,致使螺帽旋紧时芯体会随着转动,会使电缆线也跟随转动。 [0005] Further conventional shield connector inlet EMC shielding ring card, but the fit between the core and the joint connector plug can stop rotation, so that when tightening the nut with rotation of the core experience, the cable will also follow the rotation. 且其屏蔽连接头还存在装在芯体内的密封衬套会在锁紧过程中产生往外挤出现象。 And a shield connector which there is mounted a sealing liner in the core body will produce extruded out phenomenon during the locking.
