The connector is used to connect the sections of electric or seismic survey cable systems into a single line. At a significant step between the points of electrodes / seismic receivers connections, the total length of the receiving lines, their mass and dimensions in a folded state make the work inconvenient. The use of connectors of multi-wired cables allows to use the sections of acceptable length, which can be combined into a single receiving line. Standard versions of connectors are designed for switching cable systems with the number of cores 24 / 32 / 36 / 48 pcs.
