4. The plug-and-socket assembly of claim 3 , wherein the plug component is the second seal and the retaining portion is configured to secure the second seal to the distal end of the plug body by overlapping a portion of the second seal along a portion of a periphery of the distal end of the plug body.
5. The plug-and-socket assembly of claim 4 , wherein the second seal comprises a wire seal opening sleeve configured to be inserted through the second opening.
6. The plug-and-socket assembly of claim 3 , wherein the second seal forms a plurality of wire seal openings configured to surround respective wires of the cable, portions of the second seal forming the plurality of wire seal openings being integrally formed.
7. The plug-and-socket assembly of claim 3 , wherein the plug body comprises a proximal cavity at a proximal end of the plug body and a distal cavity at the distal end of the plug body.
8. The plug-and-socket assembly of claim 7 , wherein the distal cavity accommodates a terminal retainer forming a terminal hole comprising a latching mechanism, the latching mechanism being configured to accommodate an insertion of a plug terminal through the terminal hole and to resist a removal of the plug terminal from the terminal hole.
9. The plug-and-socket assembly of claim 8 , wherein the terminal retainer is located at a proximal end of the distal cavity and the second seal is located at a distal end of the distal cavity.
10. The plug-and-socket assembly of claim 7 , wherein the proximal cavity is separated from the distal cavity by a mounting floor forming a terminal hole to spatially connect the proximal cavity with the distal cavity, the proximal cavity accommodating the first seal.
11. The plug-and-socket assembly of claim 10 , wherein the first seal comprises one or more semicircular grooves configured to match an exterior form of the distal end of the socket.
12. The plug-and-socket assembly of claim 1 , wherein the longitudinal opening is configured to allow the cover to be fitted over a plug body.
13. The plug-and-socket assembly of claim 1 , wherein a distal end of the cover body comprises a groove configured to be coupled with a latching portion of a plug back cover.
14. A cover comprising:
a flange forming a first opening at a proximal end of the cover and configured to be coupled to a socket;
a retaining portion forming a second opening at a distal end of the cover, and configured to secure a component of a plug between the flange and the retaining portion; and
a cover body extending from the flange to the retaining portion and configured to be mounted over a portion of the plug and a portion of the socket, the cover body forming a longitudinal opening extending from the first opening to the second opening, the longitudinal opening defining a separation at an exterior surface of the cover and extending continuously from the flange to the retaining portion to expose the plug to the outside when the plug is secured to the socket.
15. The cover of claim 14 , wherein the first opening is configured to accommodate the socket.
16. The cover of claim 14 , wherein the longitudinal opening is configured to allow the cover to be fitted over a plug body.
17. A plug comprising:
a plug body;
a first seal at a proximal end of the plug body and comprising a flexible material configured to be compressed around a distal end of a socket; and
a second seal at a distal end of the plug body and comprising a flexible material forming a plurality of wire seal openings, the second seal being configured to:
be compressed around a plurality of wires; and
be secured to the distal end of the plug body by a retaining portion of a removable cover, the retaining portion extending along a periphery of the distal end of the plug body,
wherein the second seal comprises a plurality of wire seal opening sleeves formed around corresponding ones of the plurality of wire seal openings.
18. The plug of claim 17 , wherein portions of the second seal forming the plurality of wire seal openings are integrally formed.
19. The plug of claim 17 , wherein the plug body comprises a proximal cavity at a proximal end of the plug body and a distal cavity at the distal end of the plug body.
20. The plug of claim 19 , wherein the distal cavity accommodates a terminal retainer forming a terminal hole comprising a latching mechanism, the latching mechanism being configured to accommodate an insertion of a plug terminal through the terminal hole and to resist a removal of the plug terminal from the terminal hole.
