Currently, physical therapy equipment is widely applied in physical therapy. If the Type-C plug is used directly as a plug for the conductor of a physical therapy device, the electric current that is incompatible with the conductor may be too high.If the plug of the conductor of the physical therapy device is mistakenly inserted into the body of the physical therapy device, the electrode sheet may be inserted into the human body.

In order to solve the above problem, the present inventors installed a protrusion that has the same height as the first insertion part on the gripping part of the plug, so that the plug can be inserted into a standard Type-C socket. We have discovered that this can be prevented. For example, the gripping part of the plug is connected to the first insertion part of the plug, and the gripping part has a protrusion that surrounds the first insertion part and has a height larger than that of the first insertion part. A one-round gap is formed between the protrusion and the first insertion part, and the gap is used to fit the second insertion part of the lead socket in the physical therapy device, and the plug The Type-C socket can be inserted into the body of physical therapy equipment with a matching design with the conductor plug, but equipment that does not have improved Type-C sockets, such as the body of physical therapy equipment with too high current or commercial electrical equipment. to prevent injury to the human body. Further, the first insertion part has the same external shape as the insertion part of the Type-C plug, and the protrusion is centrally symmetrical with respect to the center line of the first insertion part.

The second end of the wire 120 may be electrically connected to the electrode sheet through a connection pin 130 or a button. Both ends of the wire 120 are electrically connected to the plug 110 and the electrode sheet, respectively, so that the electric signal received by the plug 110 is transmitted to the electrode sheet, and the electrode sheet contacts the human body to perform physical therapy on the human body. .

The second end of the gripping part 111 is connected to the first insertion part 112 to fix the first insertion part 112 to the gripping part 111 .

A center line exists in the insertion part of the Type-C plug, and the insertion part is centrally symmetrical with respect to the center line, so that the Type-C plug can be inserted in the forward or reverse direction. Since the first insertion part 112 and the Type-C plug insertion part have the same external shape, the first insertion part 112 also has a center line, and the first insertion part 112 is centered with respect to the center line. It is symmetrical, that is, after the first insertion part 112 rotates 180 degrees around the center line, it overlaps with the first insertion part 112 before rotation. As will be understood, each cross section of the first insertion section 112 that is perpendicular to the centerline of the first insertion section 112 is defined by the center point of the cross section (the two points of the first insertion section 112 shown in FIG. 3). It is centrosymmetric with respect to the intersection point of the broken lines). The center point is the intersection of the cross section of the first insertion part 112 and its center line, and the first insertion part 112 is divided into a plurality of cross sections along the direction perpendicular to the center line of the first insertion part 112. can be decomposed, and each cross-section is centrosymmetric about its own center point.

The height of the protrusion 113 is the same as that of the first insertion part 112, and the height of the first insertion part 112 is limited when inserted into a Type-C socket that is not designed to be compatible with the protrusion 113. 110, the Type-C socket cannot be inserted into unimproved equipment, such as physical therapy equipment or commercial electrical equipment with too high current, to avoid injury to the human body. Further, the first insertion portion 112 has the same external shape as the insertion portion of the Type-C plug 110, and the protrusion 113 is centrally symmetrical with respect to the center line of the first insertion portion 112, so that The plug 110 of the lead wire 100 of the improved physical therapy device according to the embodiment of the present application can also be inserted in forward and reverse directions, making it easy to use and improving the user's experience.

In an alternative embodiment, protrusion 113 is made of an insulating material.

If a current leak occurs during use of the physical therapy device, the protrusion 113 will become electrically charged unless the protrusion 113 is insulated, and if the human body accidentally touches the protrusion 113, the human body will receive an electric shock. The protrusion 113 is made of an insulating material, which can reduce the charging state of the protrusion 113 and further reduce the risk of electric shock to the human body.

The plug of the conductor wire of the conventional physical therapy equipment has a round head, and when the physical therapy equipment body transmits different signals to different wires, the number of plug signal pins is limited, so one plug has two wires. Can only be connected to wire rods. If the physical therapy equipment itself needs to transmit four different signals to four wires, it requires two plugs, and the physical therapy equipment also needs to have more conductor sockets, which increases cost.
