Abstract
The utility model relates to a heat-dissipating plate structure of a detachable generator negative electrode diode. An installing hole of a generator end cover is provided with an internal thread which is connected with an external thread arranged on the outer surface of the generator negative electrode diode, and the wire at the other end of the generator negative electrode diode is welded on a welding sheet of a rectifier bridge circuit board. The heat-dissipating plate structure disclosed by the utility model has the advantages that once a rectifier bridge fails due to the diode, the diode can be conveniently detached to be replaced, and the end cover can not be invalid, so that the production repair process and the after-sales repair process are convenient, and the cost is saved.
Description
Technical field
The utility model is suitable for a kind of detachable generator negative pole diode radiating plate structure of vehicle-mounted dlternator.
Background technology
The structure of existing vehicle alternator non-rectifying bridge negative pole heating panel is, the negative pole diode adopts interference fit to be fitted in generator end by the hole that covers with generator end and covers, be welded on then on the bonding pad of rectifier circuit plate.In case the bad or punch through damage of some or several diodes because installing hole is extended on the end cap, can't be restored, and causes the generator rear cover assembly to scrap inefficacy.Cause after cost to increase production rework process and after-sales service inconvenience.
Summary of the invention
The purpose of this utility model is to solve above-mentioned existing existing problem, a kind of dismounting is provided, changes the detachable easily generator negative pole diode radiating plate structure of diode.
The utility model is achieved in that the installing hole of generator ' s cover is provided with internal thread and has external screw thread with generator negative pole diode outer surface and be connected, and the wiring of the generator negative pole diode other end is welded on the bonding pad of rectifier circuit plate.
Advantage of the present utility model is: rectifier bridge is in case because of diode fails, and the dismounting and change diode can not cause end cap to lose efficacy easily, makes production rework process and after-sales service process convenient, saves cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Describe in detail below in conjunction with accompanying drawing: as shown in the figure, the installing hole 3 of generator ' s cover 2 is provided with internal thread and has external screw thread with generator negative pole diode 1 outer surface and be connected, and 1 other end wiring of generator negative pole diode is welded on the bonding pad 5 of rectifier circuit plate 4.
Claims (1)
1. a dismounting, change the detachable easily generator negative pole diode radiating plate structure of diode, it is characterized in that, the installing hole of generator ' s cover is provided with internal thread and has external screw thread with generator negative pole diode outer surface and be connected, and the wiring of the generator negative pole diode other end is welded on the bonding pad of rectifier circuit plate.
