Abstract
The utility model belongs to power semiconductor device technical field.The utility model is intended to the shortcoming overcoming traditional GTO ceramic cartridge, provides a kind of negative electrode not need welding, and anode copper billet and sealing ring do not need the novel GTO ceramic cartridge welded yet, and are characterized in that negative electrode copper billet itself is from flanged; Anode copper billet carries sealing ring.
Description
Technical field
The utility model relates to the structure of GTO shell, belongs to power semiconductor device technical field.
Background technology
GTO is that the one of SCR derives from device, and withstand voltage height, electric current are large, withstanding surge is strong, are wholly-controled device, are widely used in high pressure/High power Traction, industry and power converter system.
Current GTO ceramic cartridge negative electrode with the structure of anode be: negative electrode copper billet 1 and cathode flange 2 are welded to form shell negative electrode; Anode flange 3 is welded to form shell anode with pottery 4, sealing ring 5 and anode copper billet 6 and gate lead 7.As shown in Figure 1.
The shortcoming that this structure exists is: weld seam is many, and a set of ceramic cartridge has four pads, and the probability of welding gas leakage increases, and air-tightness reduces; Weld seam is many simultaneously, causes the consumption of solder (silver solder) to increase, is unfavorable for the saving of material; When sealing ring and anode copper billet and gate lead are welded simultaneously, due to gate lead and anode copper billet and sealing ring weld seam excessively near, the phenomenon of gate lead adhesion anode copper billet can be produced, cause waste product to increase; Copper billet is connected with flange or sealing ring by solder, after high-temperature soldering, because solder is different with the coefficient of expansion of copper billet, when cooling, the flatness of copper block surface also can be caused to be deteriorated, affect electrical property and the heat conductivility of semiconductor device.
Utility model content
The utility model is intended to the shortcoming overcoming GTO traditional structure ceramic cartridge, provides a kind of negative electrode not need welding, and anode copper billet and sealing ring do not need the novel GTO ceramic cartridge welded yet, as shown in Figure 2.
The technical solution of the utility model is: shell negative electrode forms flange by Vehicle Processing; Anode copper billet forms sealing ring by Vehicle Processing;
Described negative electrode copper billet itself is from flanged; Described anode copper billet carries sealing ring.
The utility model (Fig. 2) is compared with traditional structure (Fig. 1), and tool has the following advantages:
1, decrease two welding position A and B, remaining 2 of welding position, adds shell air-tightness.
2, in manufacturing process compared with traditional structure, decrease the consumption of solder.
3, stop the phenomenon of gate lead and anode copper billet and sealing ring adhesion, improve the qualification rate of product.
3, copper billet and flange and sealing ring welding, improve the flatness of shell table top.
Accompanying drawing explanation
Fig. 1 tradition GTO ceramic cartridge structural representation;
This novel practical of Fig. 2 structural representation.
Embodiment
As shown in Figure 2: GTO ceramic cartridge negative electrode only has a single negative electrode 1(to go out flange by Vehicle Processing); GTO shell anode is by anode flange 2; Ceramic ring 3; And anode copper billet 4(goes out sealing ring by Vehicle Processing) and gate lead 5 form.
Claims (3)
1. novel GTO ceramic cartridge, its feature comprises shell negative electrode and only has a single negative electrode (going out flange by Vehicle Processing); Shell anode is by anode flange; Ceramic ring; And anode copper billet composition.
2. novel GTO ceramic cartridge according to claim 1, is characterized in that: negative electrode copper billet itself is from flanged.
3. novel GTO ceramic cartridge according to claim 1, is characterized in that: anode copper billet carries sealing ring.
