Abstract
The utility model relates to a cavity direct-inserted power housing, comprising a housing (2) and a substrate (1). A set of eduction holes (1a) is arranged in the substrate. The power housing is characterized in that every eduction hole is connected with a transition ring (5), a lead pin (3) is mounted in the transition ring and a glass insulator (4) is connected between the lead pin and the transition ring. The beneficial effects of the cavity direct-inserted power housing are that sealing performance of the cavity direct-inserted power housing is ensured, the pure copper-material substrate is instead of the carbon-steel material substrate, thermal conductivity of the cavity direct-inserted power housing is raised, heat generated by an internal circuit can be rapidly transmitted to external environments to a large extent and device failure caused by heat aggregation is avoided.
Description
Technical field
The utility model relates to a kind of capsul, particularly relates to the direct insertion power shell of a kind of cavity.
Background technology
The direct insertion shell of cavity is the main packing forms of power hybrid integrated circuit, its baseplate material is generally the good cold-rolled steel of thermal conductivity, the heat that internal circuit is produced is delivered to the external world rapidly, avoid the hot polymerization collection to cause component failure, but the conductive coefficient of the thermal conductivity ratio copper of cold-rolled steel is less, and namely the thermal conductivity of copper is better than cold-rolled steel.In order to improve the thermal conductivity of the direct insertion shell of cavity, if adopt copper as its baseplate material, the matched seal fully of substrate and glass insulator will occur, and cause the problem of the sealing deficiency of capsul.
Summary of the invention
The purpose of this utility model is to solve substrate and the glass insulator of fine copper material can't fully matched seal problem.
The purpose of this utility model is achieved by the following technical programs:
The direct insertion power shell of cavity comprises shell and substrate, and substrate is provided with one group of fairlead, it is characterized in that also being connected with transition rings in each fairlead, is provided with terminal pin in the transition rings, is connected with glass insulator between terminal pin and the transition rings.
The material of described matrix is fine copper.
The beneficial effects of the utility model are in the sealing of guaranteeing the direct insertion power shell of cavity, realized that the substrate of fine copper material substitutes the substrate of carbon steel material, improved the thermal conductivity of the direct insertion power shell of cavity, can reach the heat that to a greater extent internal circuit is produced and be delivered to the external world rapidly, avoid the hot polymerization collection to cause component failure.
Following constipation closes drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is plan structure schematic diagram of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment:
As shown in Figure 1 and Figure 2, the direct insertion power shell of the cavity that the utility model provides, comprise shell 2 and substrate 1, substrate is provided with one group of fairlead 1a, welding is connected with transition rings 5 in each fairlead, be provided with terminal pin 3 in the transition rings, be sintered to fix by glass insulator 4 between terminal pin 3 and the transition rings 5.
Claims (1)
