14.3. Electric sockets - general informationThe majority of contact sockets of chains of onboard electric equipment are manufactured of plastic and are multicontact. Reliability of a joint of half of such sockets is provided with a zashchelkivaniye of lock uvulas of the clamps which are built in in plugs. Large sockets, such as some from located under the car dashboard, are most often fastened with the through bolts passed through the central part of plugs.
For a rassoyedineniye of the sockets equipped with plastic clamps the small screw-driver which should wring out accurately lock uvulas usually is used (previously attentively study a design of the joined socket - often it is not simple to measure a way of fixing of its half by eye at all; some sockets are equipped with several lock knots). Pull only for the plug, and not for an electrical wiring plait, in order to avoid casual damage of the contact plugs which are built in in the socket at all.
Sockets always consist of two half, plugs of one of which enter in plugs another. When studying schematic images of sockets try to define first of all what of its half it is presented on an illustration - connected to a plait, or fixed on a component. Remember that plugs of one half of the socket are always placed specularly in relation to plugs another.
Often, at failure diagnostics of electric chains there is a need of check of tension on plugs of the joined socket. At such checks the probe of the measuring instrument is entered into the corresponding plug from the back party of the plug. Be careful, try not to bend and not to deform plugs. If nests of plugs are too small, use as the probe the unbent metal office paper clip to which then it is possible to connect a measuring instrument wire by means of a clip like crocodile.
