Abstract

The invention relates to electrical engineering. The purpose of the invention is to increase reliability. The electrical connector includes an outlet housing 1 in which contact sockets 2 are placed. In contact socket 2, a spring-loaded spring-loaded elastic element 4 with conical projections 6 is installed with the possibility of longitudinal movement. The electrical connector plug 7 has pins 8 in the form of split sleeves. When the pin 8 is inserted into the contact socket 2, the pin 8 puts pressure on the tooth 6 of the elastic element 4, bends them, and enters the contact socket 2. At the same time, the pin 8 expands and evenly presses against the inner surface of the contact socket. When bent, the tooth 6 exerts pressure on the pin 8 evenly along its length and circumference, thereby ensuring minimal contact resistance. 3 il.

The invention relates to electrical engineering, in particular, to electrical connectors used to connect various types of electrical equipment, mainly power, with the possibility of quick and convenient disconnection, and can be used in high-frequency equipment (200-400 Hz), where It is necessary to have good contact in the connector, since this equipment, as a rule, operates under a voltage of 36–42 V, which is associated with high currents.

The aim of the invention is to increase reliability.

FIG. 1 shows the proposed electrical connector in a closed state, a longitudinal section; in fig. 2 - block, side view; in fig. 3 shows an A-L in FIG. 1 (increased) about

The proposed connector includes an outlet housing 1 in which pin sockets 2 (FIGS. 1 and 2) with fastening screws .3 and conductors are placed. In the contact socket 2 there is an elastic element 4, coaxial with socket 2 (figs. 1 and 3), which is arranged with the possibility of longitudinal movement and is spring-loaded with a return spring 5 (fig. 1). The elastic element 4 has conical protrusions whose longitudinal section has a saw-tooth shape 6 (or in the form of a fir-tree) with teeth inclined to the side opposite to the connector connector. The plug 7 has pins 8 with screws 1 1H 9 for fastening the conductors, while the pins 8 are made in the form of split sleeves (Fig. 3). The elastic element can be made of any material (metal, plastic, etc.). ) in any way (turning, pressing, casting) and can have any form of longitudinal profile, functionally equivalent to that shown. For example, an elastic element can be full in B1 than a rod with branches (like a Christmas tree), etc. The outer transverse dimension of the elastic element, i.e. the maximum transverse dimension of the surface, which is the geometric locus of the points — the ends of the teeth must be larger than the internal diameter of the pin. The specific value of this dimension is determined by the elasticity of the materials of the elastic element and the pin.

Plug 7 and socket 1 may have clamps or other elements (not shown) that are commonly used to look for contact elements when the connector is open.

The proposed connector is as follows.

When the pin 8 is inserted into the contact socket 2, it exerts pressure on the tooth 6 of the elastic element 4, bends them, and enters the contact socket 2. At the same time, the pin 8, which is made E; in the form of a split sleeve, expands (Figs. 1 and 3), evenly pressing against the inner surface of the contact socket.

6, the pressure on the pin 8 is evenly distributed along its length and circumference, thereby ensuring minimal contact resistance. In this case, the effect of the Christmas tree or the ruff prevents arbitrary opening.

To unplug the connector plug

The 7 is removed from the socket 1 (or vice versa), while the elastic element 4 moves with the pin 8, compressing the return spring 5. The latter determines the breaking force of the connector. When a large part of the pin 8 comes out of the pin socket 2, the elastic element 4 is released and the crown is rotated to the initial position of the spring. five.

By: 1o; The radiating effect is achieved by increasing reliability.

Claims (1)

Invention Formula The electrical connector, which is w; it consists of two mating parts, a plug and a socket, in the cases of which a slotted slot and a socket with a resilient volume, which are provided with a returnable connector, are provided with a rod with conical protrusions, the acute angle of which is directed in the direction opposite to the counterpart, with the elastic element mounted in the cavity of the socket with the possibility of axial movement, the conical protrusions interact with the cylindrical surface of the duct and pin, and the return spring interacts with the elastic element and the socket.
