Detailed ways

Please refer to the basic-level surge absorber and its array structure of the present invention shown in Fig. 1 and Fig. 2, the basic-level surge absorber element 10 of the present utility model includes: a metal oxide ceramic material with varistor characteristics The manufactured body 1 is provided with external terminals 2 at both ends of the main body 1, and between the interior of the main body 1 and the external terminals 2 is provided with a first electrode layer 3a, a second electrode layer 3a and a second electrode layer 3a, which are arranged in a staggered up and down and horizontal shape at a certain interval. The electrode layer 3b and the intermediate electrode layer 4, wherein the first electrode layer 3a and the second electrode layer 3b are separated at two ends and arranged in parallel, and a layer of intermediate electrode is covered between the first electrode layer 3a and the second electrode layer 3b Layer 4, in this way, an independent conduction region 5 is formed in the overlapped portion of the first electrode layer 3a and the second electrode layer 3b with the intermediate electrode layer 4, thereby using the conduction region 5 as a common electrode, and forming a parallel first electrode layer. The electrode layer 3 a and the second electrode layer 3 b are connected in series to form a structure of two surge absorber elements 10 connected in series inside the main body 1 .

Due to the fact that the first electrode layer 3a and the second electrode layer 3b of the two layers of electrodes are arranged horizontally, when covering and overlapping with the middle electrode layer 4, the thickness will not increase too much, and the surge absorber element 10 of the present invention can By using two traditional surge absorber components, and compared with the previously applied structure in which the upper and lower three-layer electrode layers are overlapped at intervals, the thickness of the volume is reduced.
