Description

The invention relates to electrical engineering, in particular to switching products, and can be used in the manufacture of switching equipment.

The purpose of the invention is to increase the reliability of the contact speed and safety of work.

The drawing shows the proposed electrical connector, General view

The electrical connector consists of two detachable parts and contains metal housings 1 and 2, transitional insulating bushings 3-5, a collet contacting element 6, a cylindrical contacting element 7, a rod 8 with a cylindrical nozzle 9 and a spring 10, a leash 11, locking nuts 12 and 13.

 The electrical connector works as follows.

The ends of the connected wiring harness 14 are connected to the contact elements 6 and 7 from the side of the locking 25 connecting wiring wire.

ny nuts. When two parts of the electrical connector are articulated, the housing 1 with the insulating sleeve 3 of one of the interacting parts slides over the insulation sleeve 4 of the other part of the connector against the housing 2. The outer lugs of the collet contact element b are located under the annular groove of the cylindrical contact element 7. Lead 11 with the rod 8 is in the initial position corresponding to the free state of the spring 10. By moving the driver 11 in the guide l-shaped groove of the housing 2, the insulating sleeve 4 and the cylinder Cesky contact element 7 moves the rod 8 which is part of the collet inwardly of the end portion of the contact element 6 and, at the exposure of internal protrusions, establishes external projections springs boiling collet lobes into the annular groove of the cylindrical contact element 7, electric and mechanical obespechshza permanent connection. The leash 11 in its extreme position is locked in a L-shaped groove, fixing the working position of the gatoka B, i.e. the position at which the rod interacts with the inner lugs of the collet petals.

When disconnecting parts of the electrical connector, the leash 11 is inserted into the groove and together with the rod 8 under

the action of the spring 10 is set to its original position, while the expanding force of the rod 8 does not act on the spring collet lobes. The absence of this force leads to the exit of the external projections of the collet petals from the annular groove of the contact element 7 and both parts of the electrical connector are ready for disconnection. The presence of bevels on the external projections of the spring collet petals ensures trouble-free operation when connecting and disconnecting

between the parts of the connector. To ensure manufacturability in the manufacture and installation of the electrical connector, the transition insulating sleeve 4 is made of two parts,

installed in the housing 2 and removable with a locking nut 12. A transition insulating sleeve 5 serves to fix the contact element 6 and also to electrically insulate the place

In each part of the connector, on the side of a suitable installation wire, a corresponding lock nut 12 and 13 is placed, which provides rigidity, eliminates axial movement of the contact elements 6 and 7 relative to its housing and closes free access to the current-carrying contact part. The contact elements 6 and 7 of the electrical connector are located inside the transitional insulating bushings 3 and 4, respectively, which exclude the accidental touching of their parts under voltage. The rod 8 and the leash 11 are made of electrically insulating material for safety purposes.

The proposed technical solution allows to increase the speed and increase the reliability of contact due to the use of a spring-loaded rod with a fixed driver, as a result of which the time for fixing two interacting parts is reduced, and to improve work safety by disconnecting the elements of contacting the rod and stem made of electrical insulation. material, and the absence of protruding parts under stress.

Claims (1)

Claims of the Invention An electrical connector comprising two contact elements, one of which is an extension and another fixing, the extension contacting element being cylindrical with a tapered end section, and the fixing contact element is fitted with slots on the end part dividing it into longitudinal sections and with protrusions in the indicated areas and introduced into the expansion contact element, characterized in that, in order to ensure reliable contact, speed and safety of operation, the expansion contact The element is spring-loaded and provided with a cylindrical nozzle with a driver made of electrically insulating material, the body on the side of its outer surface is made with a guide groove parallel to the axis of the body and with an annular groove of the conical profile; and the protrusions of the locking contact element are made so that their sections facing each the friend has a spherical surface, and the areas facing the body are a conical surface that repeats the shape of a conical profile, the said annular groove of the body, moreover, said annular groove of the housing is intended to introduce said protrusions of the locking contact element, and the spherical portions of the protrusions of the locking contact elements are intended to contact the end portion of the expansion contact element.
