Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the utility model. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, known structures and processes are not described in detail to avoid obscuring the description of the utility model with unnecessary details. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in this application.

[0020] See also Figure 1-3 The utility model discloses an anti-rotation injection-molded anti-touch finger terminal, comprising a metal body 1 and an insulating body 2, wherein the metal body 1 comprises a distal end and a proximal end, wherein the distal end comprises a connector 12, and the proximal end comprises an anti-rotation portion 11; the insulating body 2 is fixedly connected to the connector 12, and after the connection, the insulating body 2 cannot rotate relative to the metal body 1, and the insulating body 2 completely covers the connector 12; the insulating body 2 is fixed to the distal end of the metal body 1 by being connected to the connector 12, and the anti-rotation portion 11 can prevent the anti-touch finger terminal of the present application from rotating, wherein the insulating body 2 is integrally formed at the position of the connector 12 by injection molding, and the injection molding method can effectively prevent the insulating body 2 from falling off.

[0021] In one embodiment, the connector 12 includes a first connector and a second connector, the first connector and the second connector are distributed along the axial direction of the connector 12, and the first connector 12 and the second connector 12 are used to limit the axial movement of the insulating body; the first connector and the second connector can form two connectors, thereby increasing the stability of the connection.

[0023] In one embodiment, the first connection position is an annular groove 124 opened circumferentially around the connection column 122; the annular groove 124 can form a secondary stepped groove structure with the connection column 122, thereby making the axial connection more stable.

[0024] In one embodiment, the second connection position is a through hole 123 that radially penetrates the connecting column 122. The setting of the through hole 123 allows the insulating body 2 and the metal body 1 to no longer be simply attached to the surface of the metal body 1, but become one with the metal body 1, and can prevent the plastic from rotating after being encapsulated.
