Gas avoids bubble, and assembling procedure is simple, improves welding efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of traditional capacitor.
Fig. 2 is the structural schematic diagram of one laminated capacitor of embodiment.
Fig. 3 is the partial sectional view at the end angle of one laminated capacitor of embodiment.
Fig. 4 is the structural schematic diagram of two laminated capacitor of embodiment.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing, but the utility model
Embodiment is not limited to this.
Fig. 1 show the structural schematic diagram of the traditional capacitor of four dispatch from foreign news agency pole units, and Fig. 2-3 is the reality of the utility model
Example one, including capacitor ontology 1 are applied, the side of the capacitor ontology 1 is provided with the dispatch from foreign news agency pole unit 2 of multiple evaginations, the capacitor
Ontology 1 includes the internal electrode layer 12 of multiple dielectric layers 11 and multiple parallelly distribute ons between dielectric layer 11, wherein described
Internal electrode layer 12 is staggeredly electrically connected with the dispatch from foreign news agency pole unit 2, wherein each layer internal electrode layer 12 is only with wherein one
A dispatch from foreign news agency pole unit 2 is attached, and is electrically completely cut off with dispatch from foreign news agency pole unit 2 described in other；And in the present embodiment one, it is described
Capacitor ontology 1 is rectangular, and the dispatch from foreign news agency pole unit 2 is four and is located at four ends angle of the capacitor ontology 1.
It further include a ceramic shell 3 in embodiment one, the ceramic shell 3 is by capacitor ontology 1 and dispatch from foreign news agency pole unit 2
It is coated on inside, i.e., covers one layer of ceramic powder, the insulator formed through sintering between 2 outer surface of dispatch from foreign news agency pole unit；Each institute
It states dispatch from foreign news agency pole unit 2 and is provided with the exit 4 for extending outwardly and running through ceramic shell 3 at middle part, the tail portion of the exit 4 is set
It is equipped with the connection end 5 for extending downward into 3 baseplane of ceramic shell, the ceramic shell 3 is corresponding in each connection end 5
Position is provided with the shield 6 of outer convex, and the shield 6 is made of the ceramic material insulating, so as to form it is multiple from
