Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Figure 1 to Figure 5 The three-phase integrated safety plug and socket shown includes a plug 1 and a socket 2. The outer surface of the plug 1 is installed with a plurality of ring conductors 3 at intervals from top to bottom. Four ring conductors 3 are used, of which three phase One is the ground wire or the N wire. The inner surface of the socket 2 matches the position of the ring conductor 3 of the plug 1 and is equipped with a plurality of ring conductors 3. The socket 2 and the plug 1 are connected by contacting and mating the ring conductor 3 surfaces. The plug 1 The interval area between the ring conductor 3 and the socket 2 is an insulating layer, and the insulating material of the interval area is PVC, ABS or rubber. The inner surface of the socket 2 is provided with a conductor installation groove 21 corresponding to the posit...

Abstract

A three-phase integrated safety plug socket comprises a plug and a socket body. A plurality of annular conductors are arranged on the outer surface of the plug from top to bottom at intervals, the position, matched with the annular conductors of the plug, of the inner position of the socket body is provided with a plurality of annular conductors, the socket body makes contact with and is connected with the plug in a matched mode by the adoption of the annular conductor surfaces, and the spacer regions of the annular conductors on the plug and the socket body are insulating layers. By the adoption of the technical scheme, alignment is accurate in automatic installation by the adoption of conductor surface contact, phase mismatch is not prone to happening, and wear of the plug and the socket body is reduced; elastic mechanisms are additionally arranged to connect discontinuous structures of the plug annular conductors, and thus tightness of the plug and the socket body is improved.

Description

technical field [0001] The invention relates to a three-phase safety plug and socket. Background technique [0002] The plug structure of the existing three-phase safety plug and socket is mainly a structure in which the three phases and the ground wire are separated, and is divided into 4 pins or 5 pins, and the corresponding socket has 4 jacks or 5 individual jacks. The socket is used in the field of automation, and in the case of automatic plugging and unplugging, there will be the following disadvantages: [0003] 1. The multi-pin socket structure makes it difficult to align the holes when inserting; [0004] 2. It is easy to be out of phase when inserted; [0005] 3. When the automatic insertion and alignment level is not accurate, the wear and tear on the pins will be large; [0006] 4. It is easy to loose after inserting. Contents of the invention [0007] The technical problem to be solved by the present invention is to provide a three-phase integrated safety...
