Abstract
The invention relates to a plug-type coupling for sheathed electrical cables, particularly for use in mining, with a flexible protective sheath which accommodates electrical conductors of the cable. The end of the sheath is gripped in a pullproof and sealed fashion between a pressed sleeve which surrounds it and an inner backing sleeve, these parts forming part of the coupling which also includes a coupling sleeve which adjoins the pressed sleeve and receives an insert which holds contact elements electrically connected to the electrical conductors. According to the invention, the pressed sleeve is joined to the coupling sleeve to form a one-piece connector to which the insert carrying the contact elements can be coupled in a pullproof fashion by means of a snap connection. The distinctive features of the sheathed cable coupling according to the invention are simplicity of construction, ease of assembly and low production cost.
