Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, but is apparent to those skilled in the art in view of the present utility model.

Examples:

referring to fig. 1-3, the embodiment is an insert plastic shell error-proofing structure, which comprises a plastic shell 1 and an error-proofing member 2; the plastic shell 1 comprises a connecting plate 11, a group of terminal hole sites 12 arranged at the top of the connecting plate 11, a positioning column 13 arranged on the connecting plate 11 and positioned at the side edge of the group of terminal hole sites 12, and a plugging end 14 arranged at the bottom of the connecting plate 11, wherein a first slot 21 corresponding to the connecting plate 11, a second slot 22 corresponding to the terminal hole sites 12, a third slot 23 corresponding to the positioning column 13 and a fourth slot 24 corresponding to the plugging end 14 are formed in the side wall of the error proofing member 2, and the first slot 21, the second slot 22, the third slot 23 and the fourth slot 24 are mutually communicated and are adapted to cover a half space structure of the plastic shell 1.

The connecting plate 11 is horizontally arranged, so that a group of terminal hole sites 12 are upwards arranged, the group of terminal hole sites 12 are arranged in the middle of the connecting plate 11 side by side, and the positioning column 13 is arranged on the central line between the group of terminal hole sites 12. The interior of the plug end 14 is provided with a socket which is fixed to a socket of the docking apparatus. The PIN of the wire is inserted into the inside of the terminal hole 12.

The top of the connection plate 11 is provided with a terminal block 15 for mounting a set of terminal hole sites 12.

In this embodiment, the first slot 21 has a square structure, and a step portion 3 for positioning the terminal block 15 is disposed between the first slot 21 and the second slot 22. When the connecting plate 1 is positioned in the first slot 21, the step part 3 limits the terminal seat 15, the second slot 22 positions one terminal hole site 12, the other terminal hole site 12 is exposed out of the error proofing part 2, and the terminal hole site 12 can be inserted with wires, so that the terminal hole site 12 and the wires form a unique corresponding relation, and the problem of misplug of the wires on the terminal hole site is avoided.

In this embodiment, the fourth slot 24 is of a square structure, the bottom of the fourth slot 24 is provided with a limiting table 31 for limiting the plugging end 14, and since the width of the plugging end 14 is smaller than that of the connecting plate 11, the limiting table 31 can block the outer wall of the plugging end 14, so that the plugging end 14 stably enters the fourth slot 24, and the shaking problem caused by overlarge space is prevented.

When the embodiment is applied, a half of the plastic shell 1 is inserted into the side wall of the error-proofing part 2, so that one terminal hole site 12 is shielded, the other terminal hole site 12 is exposed, wires can be inserted into the exposed terminal hole site 12 for assembly, the plastic shell 1 is rotated through a production line, and after the error-proofing part 2 is pulled out, the originally shielded terminal hole site 12 can be assembled by inserting wires.

In this embodiment, by arranging the error-proofing member 2, a half of the structure of the plastic housing 1 can be effectively shielded, only one terminal hole site 12 is exposed, the terminal hole site 12 and the wire form a unique corresponding assembly relationship, and the problem that the wire is misplaced in the terminal hole site 12 is effectively avoided.
