Description

The invention relates to electrical engineering and electronics. It can be used both for connecting power to electrical and electronic devices, and for switching electrical and electronic circuits that require easy disconnection or connection of contacts during operation.

Plug connectors are widely used in electrical engineering and electronics. As a rule, they consist of a plug with contact pins and a socket with contact sockets. The socket or pin is made of an elastic electrically conductive material of such a shape that when the contacts are connected, an elastic deformation of this element occurs, which provides the compression necessary for a good contact. Therefore, a force must be applied to connect or disconnect the plug connection. For this reason, it is difficult to determine whether the plug is correctly oriented relative to the outlet, and contact elements often undergo inelastic deformation. What causes the plug to fail.

To ensure a more reliable electrical contact and a more reliable fixation of the plug connection, additional structural elements are used, orienting and pressing the contacts to each other, or connecting the contact housings to each other. Moreover, the clamping is carried out by additional operations (screwing up the contact housings, shift or rotation of the clamping elements, etc.). Before disconnecting the contacts, it is also necessary to carry out the operation of releasing the contacts from the clamp or disconnecting the housings.

Known processor ZIF-connector (Zero Insertion Force) (US 6164999, 12.26.2000, 439/342), selected for the prototype, containing a matrix of contact sockets on a printed motherboard of a computer, a movable platform with holes for contact pins of the processor, a lever for displacements of the platform relative to the matrix of contact sockets. To install the processor in the socket, the lever rises perpendicular to the motherboard. In this case, the holes of the movable platform are combined with the contact sockets. The processor contact rods freely pass through the holes of the moving platform and are placed in the contact slots. This reduces the likelihood of damage to the contact elements. Next, the lever is lowered to the motherboard and fixed on the processor socket using a special protrusion. The movable platform shifts the contact rods of the processor in the direction transverse to the contact sockets and presses them against the walls of the contact sockets by the force of a fixed lever. In such a connector, the reliability of each contact depends on the accuracy of manufacture and installation of the matrix of contact sockets on the motherboard and the matrix of contact rods on the processor. To exclude the influence of inaccurate installation, increase the clamping force generated by the lever. Increases the complexity of manufacturing and installation, as well as the cost of the processor and motherboard. There is a high likelihood of the processor skewing and fixing it incorrectly. Since the clamping force of the contact rods to the contact slots is much higher than the necessary force, damage to the processor contact rods is possible during skew.

The technical result of the invention is the provision of reliable contact, facilitating the connection and disconnection of the contacts.

The technical result is achieved by the fact that there is a latch capable of holding the slider in a position in which the contact pins or plates of the plug freely pass into the contact sockets, in the middle between the contact sockets in the area of the input of the contact pins of the plug there is a release button that can open the latch when pressed on it by the body of the plug, when placing it in the plug socket, the contact slots are made in the form of clips of elastic material in the form of a curve, the area in the region of the ends to Torah either touch each other or are at a distance less than the thickness of the contact pins or plates at one end have projections arranged in the slider available for these protrusions recesses capable to shift the slide clamp and the contact pins or plates when opening the retainer. To facilitate removal of the contact pins from the contact sockets, there is a lever capable of pushing the plug out of the socket under the action of a lever or button for moving the slider.

Figure 1 shows the electrical plug in the open state.

In Fig.5 is a fragment of a plug electrical connector in the section passing through the latch with the button in the open state and in Fig.6 - in the connected state.

7 is a plug electrical connector at the time of removal of the plug from the outlet.

The plug works as follows.

In the open state (Fig. 1, Fig. 3), the protrusion 1 at one end 2 of each of the contact slots 3, being in the recess 4 (Fig. 3) of the slider 5, is held by the slider and does not end with the protrusion due to the elastic force of the contact material sockets to approach the other end of the contact socket. The slider 5 (figure 5) is held by the open position lock 6 from movement under the action of the elastic forces of the contact sockets transmitted through the protrusions 1.

When placing the plug 7 in the socket 8 (figure 2, figure 4), each of the contact pins 9 enters the contact socket 3, freely passing between the ends 2 of each of the contact sockets 3. When the contact rods 9 are completely immersed in the contact sockets 3 (Fig.6), the fork 7 with its frontal plane 10 presses the button 11 of the latch 6, releasing the slider 5 to move. By sliding the slider along the guides 12 (FIG. 2), the ends of the contact slots 2 with the protrusions 1 (FIG. 4) press the contact rods 9 to the opposite ends 2 of the contact slots 3. The correct connection of the plug with the socket is determined by clicking the latch. This eliminates the possibility of skewing (all the rods are immersed in the nests to the same depth), since the latch button is located in the middle of the outlet and works when the frontal plane in the middle of the plug presses on it.

In the connected state, all contact rods 9 (FIG. 2, FIG. 4) are securely clamped in the contact slots 2, since the clamping force of each contact rod is determined primarily by the elastic properties of the contact socket and little depends on the accuracy of installation of all contact elements. The slider 5 is held by the protrusions of the contact slots 1 in a position that does not interfere with the contact of the contact pins with the contact slots. The latch 6 with the button 11 are held by the slider 5 in a recessed state.

To remove the plug 7 from the socket 8 (Fig.7), press the slide lever 13 (instead of the lever, you can use the button that moves the slide along the guides). When turning, the lever 13 moves the slider 5 together with the protrusions of the ends 1 of the contact slots 2, releasing the contact rods 9 of the plug 7. After the latch is activated, the lever 13 continues to move and with a special protrusion 14 presses the lever of the ejector 15, which moves the plug 7 from the socket 8. After once the lever is released, the slider 5 under the action of the elastic forces of the contact sockets will return to the position in which it will be held by the latch 6 (figure 5). In this case, the button 11 rises above the receptacle. The plug connector is brought back to its initial open state (FIG. 1, FIG. 3, FIG. 5).

Thus, the proposed plug connector is convenient in operation, since in one movement, without effort, the electrical contacts are connected and fixed at the moment when all contact rods are immersed in the contact slots to the required depth, providing the necessary pressure between them; at the touch of a lever, the electrical contacts are disconnected and the plug removed from the socket. The clamping force between the contacts in each contact socket is determined by the elasticity of the spring of this socket and does not depend on the accuracy of mounting the matrix of contact sockets and matrix of contact pins or plates. The combination of reliable contact, reliable fixation of the connection, ease of connection and disconnection of the contacts of the proposed device allows the use of the invention in many fields of electrical engineering and electronics.
