Basic unit of the present utility model formula surge absorber array structure, comprise the laminar common body of an elongated, and at least two with this body as the co-array body surge absorber element that forms a line, the external connection end of this surge absorber element is located at common body two outsides respectively, and its inner set electrode layer is for establishing at interval; It is characterized in that:

Be horizontal-extending between two first electrode layers of common body interior and the second electrode lay, cover one deck intermediate electrode layer on two electrode layers, wherein the intermediate electrode layer of each surge absorber element is to adjacent surge absorber element extension and integrates, and each element is connected mutually.

Technique effect of the present utility model is, by adopting to be arranged in parallel to plural at least two electrodes, on two electrodes, cover one deck electrode, utilize electrode series connection two electrode layers that be arranged in parallel that covered, form a plurality of element connected in series thus, the number of elements that also can obtain to double simultaneously, and utilize overall structure to adopt two-layer structure setting, to dwindle component size, the electronic product volume is reduced, and reduce manufacturing cost.

Below in conjunction with accompanying drawing the utility model is elaborated.

Embodiment

See also the basic unit of the present utility model formula surge absorber and the array structure thereof of Figure 1 and Figure 2, basic unit of the present utility model formula surge absorber element 10 comprises: by having the made body 1 of metal oxide ceramic material that becomes the resistance characteristic, be provided with external connection end 2 in body 1 two ends, keep certain intervals and the first electrode layer 3a that is staggered up and down and horizontal setting in body 1 inside to being provided with between the external connection end 2, the second electrode lay 3b and intermediate electrode layer 4, wherein the first electrode layer 3a and the second electrode lay 3b set up two ends separately, and be the parallel shape setting, between the first electrode layer 3a and the second electrode lay 3b, cover one deck intermediate electrode layer 4, so, form independently conducting region 5 in the first electrode layer 3a and the second electrode lay 3b and intermediate electrode layer 4 laps, by this by conducting region 5 as common electrode, and form first parallel electrode layer 3a of high-ranking military officer and the second electrode lay 3b series connection, have two surge absorber element 10 structures of series connection mutually to be formed in body 1 inside.

By, two-layer electrode first electrode layer 3a and the second electrode lay 3b are for being horizontally disposed with, covering when overlapping with intermediate electrode layer 4, can not increase too many thickness, and surge absorber element 10 of the present utility model can be of use two traditional surge absorber elements, and compare with the structure of the electrode layer interval overlapping setting of the previous three-layer type of applying for up and down, reduce the thickness of volume.
