1. A tip for a high-frequency skin treatment apparatus irradiating uniform radio frequency (RF), the tip being coupled to a handpiece to radiate a radio frequency (RF) signal to a human body in a non-invasive way, and comprising:
a housing;
a contact portion coupled to the housing and comprising a plurality of contact pins that are configured to come into close contact with skin of the human body to irradiate the skin with the RF signal; and
a driver configured to drive the contact portion so that the contact portion radiates the RF signal according to a control signal transferred from the handpiece,
wherein each of the contact pins comprises:
a fixed frame, an upper end of which is inserted into the housing and fixed thereto;
a moving frame coupled to the fixed frame such that the moving frame is inserted into the fixed frame from a lower end of the fixed frame, the moving frame moving in a vertical direction; and
an elastic body provided inside the fixed frame and the moving frame, to be compressed or extended according to an external force received by the moving frame to thereby move the moving frame, and
the elastic body connects an upper inner surface of the fixed frame to an upper inner surface of the moving frame to prevent the moving frame from deviating from the lower end of the fixed frame,
wherein the driver comprises:
a first PCB connected to the handpiece and configured to receive the control signal;
a second PCB provided below the first PCB and connected to the contact pins; and
signal transfer pins having two opposing ends, the two opposing ends respectively passing through the first PCB and the second PCB, to communicate signals between the first PCB and the second PCB,
wherein the signal transfer pins support the first and the second PCBs such that the first and the second PCBs are maintained to be spaced apart from each other; and wherein a fitting member, which passes through the second PCB and is fitted and fixed thereto, is formed at the upper end of the fixed frame, the second PCB comprises fitting holes therein, the fitting holes being formed by perforation and having the same diameter as the outer diameter of the fitting member, and the number of the fitting holes is equal to the number of the plurality of contact pins, and the fitting holes are spaced apart from each other at regular intervals in vertical and horizontal directions in the second PCB.
