The upper concave portion 43 on the top surface is a similar circular concave portion, is similar to a bowl shape, is used for accommodating a thumb, and has a depth slightly larger than that of the lower concave portion 44 on the bottom surface, and the lower concave portion 44 on the bottom surface is arranged to extend along the width direction of the second packaging structure 4 and is used for being matched with the index finger to transversely hold.

Further, the cable connector 100 is further provided with a marking portion 5 for marking product information, where the marking portion 5 may be information sprayed on the cable connector 100, or may be a two-dimensional code, a bar code, a BF application portion, etc. provided on the cable connector 100, and the marking portion 5 may be provided at any position of the cable connector 100 according to actual situations, which is not limited herein.

The electrode patches 500 of the tumor electric field therapeutic apparatus 1000 are arranged in pairs, the cable connectors 100 are arranged in one-to-one correspondence with the electrode patches 500, the cable connectors 100 corresponding to each pair of electrode patches 500 have the same structure, and the two mutually matched sockets 200 have the same structure; the cable connector 100 cannot be plugged with the socket 200 corresponding to the other pair of electrode patches 500, and in order to avoid the mixed plugging, the positions of the limit ribs 127 of the plug 1 corresponding to the different pairs of electrode patches 500 are slightly different. For example, in fig. 1, a stopper rib 127 of the plug 1 of the cable connector 100 according to the present embodiment is provided inside the right side wall 126 (see fig. 1 and 5). The present application further provides a cable connector 100' corresponding to another pair of electrode patches (not shown) and a socket 200' matched with the cable connector 100', wherein the limit rib 127' of the plug 1' of the cable connector 100' is disposed on the inner side of the left side wall 125' (as shown in fig. 9), and the limit groove 204' of the corresponding socket 200' is disposed correspondingly. Further, the color of the cable connector 100 may be different from the color of the cable connector 100 connected to the electrode patch 500, and the color of the cable connector 100 connected to the electrode patch 500 may be different from the color of the cable connector 100.

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.
