Reliability of a joint of half of such sockets is provided защелкиванием lock uvulas of the clamps built in in tips. Large sockets, such as some of the devices of the car located under the panel, are fastened passed through the central part of tips by through bolts more often.

For рассоединения the sockets equipped with plastic clamps the small screw-driver to which should wring out accurately lock uvulas (preliminary attentively usually is used study a design of the joined socket — often to measure a way of fixing of its half by eye completely not simply; some sockets are equipped by several lock knots). Pull only for the tip, and at all for an electroconducting plait, in order to avoid casual damage of the contact plugs built in in a socket.

Sockets always consist of two half plugs of one of which enter in plugs another. At studying of 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 socket always are placed mirror in relation to plugs another.

Often at a problem diagnostics of electric chains there is a necessity of check of pressure on plugs of the joined socket.

At such checks щуп a measuring instrument it is entered into the corresponding plug from the back party of the tip.

Be careful, try not to bend and not to deform plugs. If nests of plugs are too small, take advantage in quality щупа of the unbent metal writing paper clip to which then it is possible to connect a wire of a measuring instrument by means of a clip of type a crocodile.
