Description

The invention relates to the field of electrical engineering and for the electrical connector of the system "socket-plug".

Known electrical connector containing a socket made in the form of a dielectric part with built-in electrical contacts and a cover, and a plug made in the form of a dielectric body with a pair of pins [1]. A disadvantage of the known electrical connector is its limited use in conditions of shaking, vibration, location under inclined and horizontal surfaces.

The objective of the invention is to expand the scope of the electrical connector, increasing its reliability.

The technical result is achieved by the fact that in the electrical connector containing a socket made in the form of a dielectric part with integrated electrical contacts and a cover, and a plug made in the form of a dielectric case with a pair of pins, the socket cover is equipped with a built-in permanent magnetic element, and the plug case has a built-in ferromagnetic plate. The socket cover has a central hole. The plug housing is provided with a central screw to break the contact between the permanent magnetic element and the ferromagnetic plate. The rotary head of the central screw is located in the through window of the plug housing. The rotary head of the central screw is located outside the plug housing

Figure 1 presents a General view of the electrical connector located under an inclined surface; figure 2 shows a view of the cover of the outlet from the side of the plug; figure 3 shows a section of figure 2 along aa; figure 4 shows a front view of the plug with a central screw, the rotary head of which is located in the through window of the housing; figure 5 is a top view of figure 4; Fig.6 is a side view of Fig.4; figure 7 shows a cross section of figure 4 along BB; on Fig shows a front view of the plug with a central screw, the rotary head of which is located outside its body; Fig.9 is a top view of Fig.8; figure 10 is a view of figure 8 from below.

The electrical connector (figure 1) contains a socket 1 and a plug 2. The socket is made in the form of a dielectric, for example, plastic, part 3 with integrated electrical contacts 4 and a plastic cover 5 (figure 2 and 3). A pair of permanent magnetic elements 6 is fixedly mounted in the lid. The lid has a central hole 7, openings 8 for access to electrical contacts and openings 9 for attachment by fixing screws (not shown) to the plastic part. The plug (Figs. 4-7) with an end input of an electric cable (not shown) is made in the form of a plastic case 10 with a pair of pins 11. The case has a pair of built-in ferromagnetic plates 12 and a central screw 13 made of plastic with a rotary head 14. The rotary head is located in the through window 15 of the plug housing. In the plug (Fig. 8-10) with a lateral input of an electric cable (not shown), the rotary head is located outside its housing.

The electrical connector (Fig. 1) in the form of a socket 1 and a plug 2 is installed, for example, in a vehicle cabin. When connecting the plug to the socket, the pins 11 embedded in the plastic housing 10 through the holes 8 in the cover 5 (FIGS. 2 and 3) come into contact with the electrical contacts 4 of the plastic part 3. In this case, the ferromagnetic plates 12 and the permanent magnetic elements 6 form a magnetic connection, eliminating loss of the plug from the socket during shaking or vibration that occurs, for example, when the vehicle is moving.

To separate the plug from the outlet, perform the following operations. Rotate the head 14 located in the window 15 (Fig. 4, 7) of the housing or outside the housing (Fig. 8 and 10), while the end of the central screw 13 is pushed out of the housing and, resting against the hole 7 in the cover of the socket, breaks the contact between permanent magnetic elements and ferromagnetic plates, thereby weakening the action of the magnetic field. After that, the plug is easily removed from the outlet. By turning the head in the opposite direction, the protruding outward part of the central screw is removed into the plug housing.

The invention extends the scope of the electrical connector, increases its reliability.
