Detailed Description

The invention is further described below with reference to the accompanying drawings.

The upper, lower, left and right in this embodiment are based on fig. 5, the left side in fig. 5 is the left side in this embodiment, and the right side in fig. 5 is the right side in this embodiment.

The plug insert component structure of the utility model is used for being applied to a two-pin plug, as shown in fig. 2-3, comprising a connecting terminal 1 fixedly arranged in the plug, in the embodiment, the connecting terminal 1 is a square metal sleeve composed of an upper top surface 101, a lower bottom surface 102, a left side surface 103 and a right side surface 104, the inlet area of the insert wire is large, and the wire connection is convenient; the upper top surface is a plane, the planes of the upper top surface 101 and the lower bottom surface 102 are parallel to each other, of course, the lower bottom surface 102 can also be set to be a cambered surface structure, and the lower bottom surface 102 protrudes outwards relative to the inner cavity of the terminal. Of course, other configurations of the bottom surface are possible, such as an inwardly concave or irregular arc with respect to the terminal cavity.

A metal gasket 2 is arranged in the square metal sleeve in a penetrating manner, and the metal gasket 2 can move up and down in the inner cavity of the wiring terminal 1; one end of the metal gasket 2 is connected with a receiving sheet 5 in the direction of the metal gasket 2, the receiving sheet 5 is connected with an inserting sheet 3 in the direction of the metal gasket 2, the receiving sheet 5 is a knob-shaped metal sheet and is used for controlling the included angle between the plane where the metal gasket 2 is located and the plane where the inserting sheet 3 is located, in the embodiment, the plane where the metal gasket 2 is located is perpendicular to the plane where the inserting sheet 3 is located, and the two-pin socket jack accords with the common traditional two-pin socket jack.

The other end of the metal gasket 2 is provided with a contact sheet 201, the contact sheet is an upward extending edge of the other end of the metal gasket, and the plane of the contact sheet is perpendicular to the plane of the metal gasket or has an inclined angle.

The plane of the metal gasket 2 is perpendicular to the plane of the inserting sheet 3, however, the perpendicular is preferable, the accuracy is reduced, the processing is convenient, and an included angle between the plane of the metal gasket 2 and the plane of the inserting sheet 3 is possible.

As shown in fig. 4-7, a fixing mechanism 4 for pressing wires is disposed on the upper top surface 101 of the connection terminal 1, the fixing mechanism includes a through hole 402 disposed on the upper top surface 101, a thread is disposed in the through hole 402, and the fixing mechanism further includes a screw 401 for screwing into the through hole and matching with the thread; the screw is screwed downwards, and the metal gasket is pressed downwards; the screw is screwed upwards, and the metal gasket is loosened.

The working principle is as follows: the electric wire is inserted into the position between the metal gasket 2 and the lower bottom surface 102, and the electric wire can be blocked and prevented from being inserted into the space between the metal gasket 2 and the upper top surface 101 due to the fact that the contact sheet 201 extending upwards is arranged; the screw 401 is screwed downwards, the bottom of the screw 401 pushes the metal gasket 2, so that the wire is only pressed between the lower bottom surface 102 and the metal gasket 2; the electric wire is not in direct contact with the screw 401, the stress area is increased, and the electric wire is not twisted; the upper top surface 101, the metal gasket 2 and the lower bottom surface 102 are parallel, so that the metal gasket is stressed evenly and more firmly when the screw 401 is locked downwards;
