[0023] Example 1

[0024] As Figures 1-5 shown, the embodiment includes shell 1, compression spring, pressing block 2, hose 3 and conductor 4.

[0025] The shell 1 in the embodiment comprises an upper cover 1a, a lower cover 1b and a button 1c. The upper cover 1a and the lower cover 1b are provided with grooves and are buckled together to form a cavity. The upper cover 1a and the lower cover 1b are connected by clamping, and in other embodiments, the upper cover 1a and the lower cover 1b can also be fixed by screw connection. One end of the upper cover 1a is further provided with an upper opening 1a1, and the button 1c is arranged at the opening 1a1. One end of the button 1c is clamped on the lower cover 1b, and the other end of the button 1c is provided with a pressing portion 1c1. In other embodiments, one end of the button 1c can also be fixed on the upper cover 1a.

[0026] In the embodiment, a rectangular mounting groove 1b1 is arranged in the groove of the lower cover 1b, and in other embodiments, the mounting groove 1b1 can also not be arranged. The compression springs are arranged in the mounting groove 1b1. In order to ensure balance, two compression springs are arranged at both ends of the mounting groove 1b1. The rectangular pressing block 2 corresponding to the shape of the mounting groove 1b1 is pressed on the compression springs and partially immersed in the mounting groove 1b1. The pressing block 2 has another part corresponding to the pressing portion 1c1.

[0027] The pressing portion 1c1 in the embodiment refers to a plastic area that allows a certain deformation. By pressing the pressing portion 1c1, the pressing portion 1c1 presses down the pressing block 2, and the pressing block 2 sinks in the mounting groove 1b1. When the pressing portion 1c1 is released, the pressing block 2 is reset under the action of the compression spring. In other embodiments, the other end of the button 1c can also be provided with an opening, and a part of the pressing block 2 extends out of the opening. The part extending out of the opening serves as the pressing portion 1c1 and can also have the same effect.

[0028] The hollow hose 3 penetrates the pressing block 2. In the embodiment, the hose 3 is made of PTFE material, and in other embodiments, the hose 3 can also be made of other flexible materials.

[0029] The conductor 4 is a rectangular thin copper sheet. The conductor 4 has two parts and penetrates the hose 3 from both sides of the pressing block 2. That is, a part of the conductor 4 is located in the pipeline of the hose 3.

[0030] Four wires 5 extend into the cavity from one end of the shell 1. The four wires 5 are divided into two groups, and each group is connected with two conductors 4. The other end of the wire 5 is connected with the plug pin 7 which can be directly inserted into the equipment interface. The electrode wire 6 is inserted into the hose 3 from the other end of the shell 1, and the two electrodes of the electrode wire 6 are in contact with the conductors 4 in the hose 3. In order to facilitate the threading of the wire 5 and the electrode wire 6, the shell 1 is further provided with a wire hole at one end and an electrode wire hole at the other end.

[0031] In this way, the electrical signal collected by the distal electrode of the electrode wire 6 is transmitted to the proximal electrode, and then transmitted to the conductor 4, and then transmitted to the wire 5, and then transmitted to the equipment through the plug pin 7.

[0032] After the electrode wire 6 is inserted into the hose 3, the hose 3 is bent upwards into a bridge shape under the action of the compression spring, and it is not easy to pull out the electrode wire 6 at this time. If it is desired to pull out the electrode wire 6, it is only necessary to press the pressing portion 1c1, so that the pressing block 2 sinks under the spring force and the hose 3 returns to the straight state, and the electrode wire 6 can be easily pulled out. Of course, if necessary, a pressing plate can be arranged in the cavity and appropriately pressed on the hose 3 on both sides of the pressing block 2, so as to limit both ends of the hose 3 from moving together when the hose 3 is bent.

[0033] Preferably, the pressing surface of the pressing block 2 is arranged as an inclined surface 2a. When the pressing portion 1c1 on the button 1c is pressed, it is in an inclined state, and the pressing surface of the pressing block 2 is also arranged in an inclined state, which is more conducive to pressing and can avoid the jamming phenomenon.

[0034] Embodiment 2

[0035] The embodiment is basically the same as the embodiment 1, and the difference is that the conductor 4 in the embodiment is only arranged on one side of the pressing block 2 and penetrates through the hose 3; the wire 5 extends into the cavity from one end of the shell 1 and is connected with the conductor 4; and the electrode wire 6 is inserted into the hose 3 from the other end of the shell 1, and the electrode of the electrode wire 6 is in contact with the conductor 4 in the hose 3.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
