Outer End Cap for Sealing an Electrical Connector as well as Connector Assembly
An outer end cap for sealing a connection end of an electrical connector includes a cover section covering an end face of the connection end and a collar section attached to the connection end. The cover section has a through-hole receiving a sensor cable of a sensor. The cover section and the collar section jointly form a receptacle receiving the connection end. An interior surface of the receptacle has a semi-conductive material. A connector seal is formed on the interior surface of the receptacle and a cable seal is formed in the through-hole.
1 . An outer end cap for sealing a connection end of an electrical connector, comprising:
a cover section covering an end face of the connection end, the cover section has a through-hole receiving a sensor cable of a sensor; and
a collar section attached to the connection end, the cover section and the collar section jointly form a receptacle receiving the connection end, an interior surface of the receptacle has a semi-conductive material, a connector seal is formed on the interior surface of the receptacle and a cable seal is formed in the through-hole.
2 . The outer end cap of claim 1 , wherein a layer of the semi-conductive material is arranged at the connector seal and/or at the cable seal.
3 . The outer end cap of claim 1 , wherein the receptacle is lined with the semi-conductive material.
4 . The outer end cap of claim 1 , wherein the connector seal and/or the cable seal are made of the semi-conductive material.
5 . The outer end cap of claim 1 , wherein the outer end cap is formed entirely of the semi-conductive material.
6 . The outer end cap of claim 1 , wherein the outer end cap is reversible.
7 . The outer end cap of claim 1 , wherein the semi-conductive material is elastomeric.
8 . The outer end cap of claim 1 , wherein the semi-conductive material is a liquid silicon rubber containing carbon black particles or ethylene propylene diene monomer rubber containing carbon black particles.
9 . The outer end cap of claim 1 , wherein the connector seal is formed by a first inwardly facing sealing lip at the collar section.
10 . The outer end cap of claim 9 , wherein the cable seal is formed by a second inwardly facing sealing lip in the through-hole.
11 . The outer end cap of claim 1 , further comprising a handling section configured to permit manipulation of the outer end cap with a hot-stick.
12 . A connector assembly, comprising:
a tee connector having a connection end and a sensor with a sensor cable, the sensor cable extends from the connection end, the tee connector has an external coating formed of a first semi-conductive material; and
an outer end cap contacting the external coating and including a cover section covering an end face of the connection end and a collar section attached to the connection end, the cover section has a through-hole through which the sensor cable extends, the cover section and the collar section jointly form a receptacle receiving the connection end, an interior surface of the receptacle has a second semi-conductive material, a connector seal is formed on the interior surface of the receptacle and a cable seal is formed in the through-hole.
13 . The connector assembly of claim 12 , wherein the external coating is connected to a reference earth.
14 . The connector assembly of claim 12 , wherein the tee connector has an inner insulating plug attached to the connection end.
15 . The connector assembly of claim 14 , wherein the sensor is integrated into the inner insulating plug.
16 . The connector assembly of claim 15 , wherein the inner insulating plug is not waterproof and the outer end cap seals the inner insulating plug against ingress of water.
17 . The connector assembly of claim 12 , wherein the sensor cable has a sensor connector connecting with the sensor.
18 . The connector assembly of claim 17 , wherein the sensor connector is not waterproof and the outer end cap seals the sensor connector.
19 . The connector assembly of claim 12 , wherein the sensor cable is a screened cable.
