The adapter is provided with a cable connected with the electric field generator and a plurality of sockets, the electrode patches are provided with wiring, and the tail ends of the wiring are provided with plugs which are in butt joint with the corresponding sockets of the adapter, so that alternating current signals of the electric field generator are transmitted to the electrode patches to form an electric field between each pair of electrode patches, and electric field treatment is carried out on tissue areas where focuses are located.

The adapter comprises an upper cover, a lower cover, a main board and a plurality of sockets, wherein the upper cover and the lower cover are clamped up and down to form a containing cavity, and the sockets are electrically connected with the main board and contained in the containing cavity together with the sockets. The upper cover and the lower cover are respectively exposed out of the plug-in interfaces of the sockets at the front side of the adapter, and the plugs of the cable connectors on the electrode patches are inserted into the plug-in interfaces and electrically connected with the sockets. In the existing tumor electric field therapeutic apparatus, in the plug-in cooperation of the plug of the cable connector and the socket in the adapter, the misalignment of the plug and the socket easily occurs, so that the plug is askew, and the connection effect of the plug and the socket is affected. In addition, the plug of the cable connector of each pair of electrode patches should be plugged with a corresponding pair of plug sockets, and the shapes of the upper and lower parts of the end surfaces of the plug interfaces of the existing plug sockets are the same, so that the shapes of the upper and lower parts of the butt joint end surfaces of the plug sockets are the same, and the correct plugging direction of the plug cannot be distinguished, so that the situation that the plug is reversely plugged easily occurs, thereby causing signal transmission errors and seriously damaging the electrode patches and the tumor electric field therapeutic apparatus.

Therefore, improvements to existing tumor electric field therapy devices and their adapters are needed.

Referring to fig. 10, the mating end 61 of the cable connector 6 includes an upper end wall 613, a lower end wall 614, and two side end walls 615 connecting the upper end wall 613 and the lower end wall 614, and the upper end wall 613, the lower end wall 614, and the side end walls 615 enclose a plugging cavity (not numbered). The distance between the upper guide post 16 and the side surface of the plugging part 33, which is close to the upper guide post 16, in the same upper guide cavity 14 is slightly larger than the thickness of the side end wall 615 of the abutting end 61 of the cable connector 6, so that hard interference with the side end wall 615 is avoided; the distance between the lower guide post 26 and the side of the plugging portion 33, which is located in the same lower guide cavity 24 and is close to the lower guide post 26, is slightly larger than the thickness of the side end wall 615 of the abutting end 61, so that hard interference with the side end wall 615 is avoided.

The upper cover 1 is provided with 5 upper guide blocks 17, and the lower cover 2 is provided with 5 lower guide blocks 27 corresponding to the upper guide blocks 17 of the upper cover 1. The 5 upper guide blocks 17 are all arranged by protruding downwards from the top wall 11 of the upper cover 1 at the position of the upper guide cavity 14; the 5 lower guide blocks 27 are all arranged by protruding upwards from the bottom wall 21 of the lower cover 2 at the position of the lower guide cavity 24. The upper guide block 17 and the lower guide block 27 constitute the aforementioned guide block (not numbered). The distance between the upper guide block 17 and the lower guide block 27, which are located in the same guide chamber 107, is substantially equal to the distance between the upper end wall 613 and the lower end wall 614 of the docking end 61 of the cable connector 6; the distance between the upper guide block 17 located in the same upper guide cavity 14 and the top surface of the plug-in portion 33 adjacent thereto is approximately equal to the thickness of the upper end wall 613 of the butt end 61; the distance between the lower guide block 27 located in the same lower guide cavity 24 and the bottom surface of the plug section 33 adjacent thereto is approximately equal to the thickness of the lower end wall 614 of the abutment end 61.

When the upper cover 1 and the lower cover 2 are buckled, guide posts (not numbered) which are arranged on two sides of the guide cavities and are arranged towards the inner protrusions of the guide cavities and guide blocks (not numbered) which are arranged on two ends of the top and the bottom of the guide cavities and are arranged along the vertical protrusions of the guide cavities are arranged in each guide cavity 107, so that the cable connector 6 can be accurately aligned with the socket 3 and firmly spliced on the socket 3 under the guidance of the guide posts (not numbered) and the guide blocks (not numbered) in the process of splicing the cable connector 6 towards the socket 3.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
