Description

one

An electrical connector is known, consisting of two parts, each of which comprises a housing, a terminal block and a bellows.

However, the known connector is not reliable enough.

In the proposed electrical connector, in order to increase reliability, at least one of the connector parts is provided with a flange placed at the articulation side, the bellows is located inside the housing, covers the terminal block and is attached with one end to the base of the latter, and the other to said flange.

FIG. 1 shows the stationary part of the connector, closed with a cap-cap in the longitudinal section; in fig. 2 - fixed fixed part of the connector, top view; in fig. 3 shows a removable part of a connector for connecting with a flexible cable in a longitudinal section; in fig. 4 - remove part of the connector, top view.

The stationary part / connector consists of a flange 2 of the housing 3, inside which a contact pad 4 is installed, containing a metal cup 5 integrated with the housing 5 with a pin 7 pressed into the insulator 6, covering the contact pad mounted in the cavity of the bellows 8, fixed from the side the articulation in the groove of the annular protrusion of the flange 9, and on the opposite side between the ring W and the base of the metal cup 5.

The stationary part of the connector is provided with an lid I, for fastening of which on the flange 9 there are shaped pins 12, and in the slots of the tides of the housing 3 on the axles there are fixed studs 13 with wing nuts J4.

The cover has an eye 15 for securing the chain (the latter is not shown in the drawing), which protects the cover from being lost when it is removed from the connector.

In the annular groove of the housing 3 there is a sealing gasket 16, and in the annular groove on the inside of the lid there is a gasket 17, with the annular grooves of the housing and the lid corresponding to the annular projections of the flange. In the lid}. figured slots J8 are made according to the number of shaped pins (Fig. 2).

The removable part of the connector 19 (Fig. 3) consists of the housing 20 with the cup 21 located at its center and integral with the cup 21 with the socket contact 23 pressed into the insulator 22. In the annular groove of the flange part 24 of the housing 20 a sealing strip 25 is placed. In the flange portion 24 there are also annular slots 26, similar to the slots 18 (Fig. 2). The bellows 27 of the detachable part of the connector is fixed on the flap 28 by supplying shaped pins 29, similar to the pins 12 mounted on the flange part 24 of Cornus 20.

To the female contact 23 a cable core is connected, which is sealed by a gasket, pressed by a gland nut. In the stationary part of the connector, which is presented in a closed form, when its removable part is connected to it (Fig. 1), the annular flange 9 lies on the flange part 30 of the housing 5. At the same time, the cover 11 is inserted with figured cuts 18 by the shaped pins 12 so that it is pressed against the flange 9, and the whole structure is sealed with folding clamps consisting of folding studs 13 and wing nuts 14. The bellows 8 in this case is compressed and is in the inner cavity of the housing 3. With the bellows length equal to 1 m corrugation width of 10 mm and the thickness of the material of the bellows 1.5 mm bellows compressed with standing, it has a height of 150-200 mm.

When it is necessary to connect the detachable part of the connector to its stationary part, the wing nuts 14 are loosened, the stud bolts 13 are thrown off to the side. thereto, since the shaped pins 12 are suitably inserted into the figured cap slots 18, and the bellows 8 is pulled out of the cavity in the housing 3.

Thus, the contact part of the stationary connector will be protected from water vapor (water can penetrate

only part of the cavity of the connector body outside the bellows).

Next, by turning the cover // output t heads of the pins 12 of the figured slots in the cover and remove the cover from the flange.

After the cover is removed, the removable part of the connector attaches to the flange 9, the flange part of which is similar to the flange part of the cover 11, then the removable part of the connector together with the flange 9 is lowered onto the stationary part of the connector. In this case, the pin contact 7 enters the corresponding female contact 23, then the studs 13 with the wing nuts 14 are inserted, and the connector is finally unlocked.

In the described device, splashing of seawater into the cavity of the connector contacts is excluded. Leaving the water in the cavity of the Cornus does not penetrate to the connector pins, however, it can be removed through fitting 31.
