Fig. 1 is a schematic view of the overall structure of the present invention.

Detailed Description

The first embodiment is as follows: referring to fig. 1, the transformer tap inserting apparatus according to the present embodiment includes a plug 1, a socket 2, a connecting terminal 3 and a wire 4, wherein the connecting terminal 3 is disposed in the socket 2, one end of the wire 4 is connected to a transformer, and the other end of the wire 4 passes through an outer wall of the socket 2 and is connected to the connecting terminal 3; this embodiment still includes two locating component, and the symmetry is equipped with two location breach 11 on the lateral wall of plug 1, two locating component symmetry is installed on the outer wall of socket 2, and behind plug 1 inserted socket 2, locating component can peg graft with the location breach 11 one-to-one on the outer wall of plug 1.

In this embodiment, after the plug 1 is inserted into the socket 2, the connector 12 of the plug 1 is inserted into the connecting terminal 3 to realize connection.

The second embodiment is as follows: the present embodiment is described with reference to fig. 1, and each of the positioning assemblies of the transformer tap inserting device of the present embodiment includes a pressing plate 5, a spring 6, a positioning pin 7 and a supporting rod 8, one end of the supporting rod 8 is fixedly connected to an outer wall of the socket 2, a middle portion of the pressing plate 5 is hinged to the other end of the supporting rod 8, a through hole 21 is formed in the outer wall of the socket 2, the positioning pin 7 is inserted into the through hole 21, an outer end of the positioning pin 7 is hinged to one end of the pressing plate 5, and the other end of the pressing plate 5 is connected to the outer wall of the socket 2.

After the plug 1 is inserted into the socket 2, when the positioning notch 11 passes through the inner end of the positioning pin 7, the positioning pin 7 is inserted into the positioning notch 11, so that the plug 1 cannot be pulled out of the socket 2, when the plug 1 needs to be pulled out, the other ends of the two pressing plates 5 are pressed down simultaneously, so that the inner end of the positioning pin 7 leaves from the positioning notch 11, and the plug 1 can be pulled out at the moment.
