Description
Technical field
The utility model relates to a kind of vehicle rectifier diode, belongs to technical field of electronic devices.
Background technology
AC generator for vehicle and storage battery form the electric power system of automobile, and the alternating current that alternator frame winding produces needs rectification, become direct current and can supply automotive electrical system use.Rectifier diode is the core devices completing rectification function in generator.Because automobile current generator is arranged near engine, during work, temperature is high, vibration is large, and the heat of the power consumption generation of diode in addition own, diode operation condition is very harsh, therefore very high to the Structural Design Requirement of diode.
Rectifier diode is generally designed to pressing type structure, primarily of base, chip, lead-in wire composition, then with fluid sealant embedding protection.Traditional lead-in wire is made up of heading and lead-in wire two parts.The shortcoming of this lead-in wire is: after diode package, when go between in assembling process stressed bending time, be easy to fluid sealant is broken, thus cause seal failure, diode service life shorten.
Utility model content
The technical problems to be solved in the utility model is, proposes a kind of vehicle rectifier diode of good sealing effect.
The utility model is the technical scheme solving the problems of the technologies described above proposition, a kind of vehicle rectifier diode, comprise lead-in wire, chip, base and seal cover, lead-in wire is connected with chip, chip is positioned at base upper surface, base upper surface is also provided with ring screw groove, thread-groove bottom is also provided with sealing gasket, seal cover is the tubular of closed upper part lower openings, seal cover is positioned at above base and lower end is plugged in thread groove, seal cover is connected with base by thread, seal cover top also offers circular hole, circular hole place is provided with tubular rubber ring, rubber ring is closely fixedly connected with seal cover, go between through rubber ring during use and closely cooperate with rubber ring.
Being improved to further of the technical program: described seal cover and rubber ring junction are provided with boss, add the stability of connection.
The beneficial effects of the utility model are:
1, change traditional diode seal form, chip does not contact with other materials, avoids damage.
2, seal cover adopts with base and is threaded, easy for installation; Be provided with rubber ring between seal cover and lead-in wire, both played sealing function, again the rolling power of available buffer lead-in wire, good sealing effect.
3, encapsulation process does not need to use fluid sealant, encapsulation process simplification.
Accompanying drawing explanation
Be described further of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of a kind of vehicle rectifier diode of the utility model.
Fig. 2 is the vertical view of a kind of vehicle rectifier diode of the utility model.
The Reference numeral of above-mentioned accompanying drawing is:
Lead-in wire 1, chip 2, base 3, thread groove 31, sealing gasket 32, seal cover 4, boss 41, rubber ring 5.
Embodiment
Below by embodiment, the utility model is specifically described:
Embodiment one
A kind of vehicle rectifier diode of the present embodiment as depicted in figs. 1 and 2, comprise lead-in wire 1, chip 2, base 3 and seal cover 4, lead-in wire 1 is connected with chip 2, chip 2 is positioned at base 3 upper surface, base 3 upper surface is also provided with ring screw groove 31, sealing gasket 32 is also provided with bottom thread groove 31, seal cover 4 is the tubular of closed upper part lower openings, seal cover 4 is positioned at above base 3 and lower end is plugged in thread groove 31, seal cover 4 top also offers circular hole, circular hole place is provided with tubular rubber ring 5, and rubber ring 5 is closely fixedly connected with seal cover 4.Seal cover 4 and rubber ring 5 junction are provided with boss 41.
When a kind of vehicle rectifier diode of the present embodiment uses, lead-in wire 1 passes rubber ring 5 and closely cooperates with rubber ring, then seal cover 4 lower end is screwed in thread groove 31; When lead-in wire 1 rocks, rubber ring 5 plays the effect of buffering, good sealing effect.
Embodiment two
A kind of vehicle rectifier diode of the present embodiment, comprise lead-in wire 1, chip 2, base 3 and seal cover 4, lead-in wire 1 is connected with chip 2, chip 2 is positioned at base 3 upper surface, base 3 upper surface is also provided with ring screw groove 31, sealing gasket 32 is also provided with bottom thread groove 31, seal cover 4 is the tubular of closed upper part lower openings, seal cover 4 is positioned at above base 3 and lower end is plugged in thread groove 31, seal cover 4 top also offers circular hole, circular hole place is provided with tubular rubber ring 5, and rubber ring 5 is closely fixedly connected with seal cover 4.
A kind of vehicle rectifier diode of the present utility model is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop in the protection range of the utility model requirement.
