Abstract
The utility model discloses a bridge rectifier support for an automobile generator. The bridge rectifier support for the automobile generator includes a support, rectifier assembly holes, lock hood cover screw thread holes, diode welding lead structures, stator wire connection structures and phase terminal lead structures. The bridge rectifier support is irregular semicircle-shape. The bridge rectifier support is characterized in that insulation pads are arranged in the rectifier assembly holes; insulation pads are in the lock hood cover screw thread holes; when molding is performed, the insulation pads are embedded in the rectifier assembly holes and the lock hood cover screw thread holes, so that injection molding can be performed. According to the bridge rectifier support, the matrix of the rectifier bridge support is made of PA66, the insulation pads are made of BMC materials; and when molding is performed, the insulation pads are designed into anti-rotation and anti-dropping structures, and therefore, embedding of copper nuts is not required, and the failure of the insulation pads which is caused by rotation of the insulation pads with the nuts in a fastening process can be avoided. Compared with all PPS used before, with a more excellent fastening function ensured, material cost is reduced by 55%, and time is greatly reduced.
Description
Technical field
The utility model relates to automobile current generator fixedly assembly structure of rectifier bridge support, especially a kind of automobile current generator rectifier bridge support.
Background technology
Automobile current generator is that conduction main on rectifier connects and fixed support part with rectifier bridge support, after bridge bracket can being welded to diode while being assembled into rectifier, be fixed on electric motor end cap together with positive plate, for the work that guarantees that diode and rectifier can be continual and steady, just need to guarantee that support+pole plate+end cap is connected firmly, avoid loosening when high temperature or vibration, otherwise rectifier can cause virtual connection or lose efficacy because vibration causes diode lead to break because of fastening becoming flexible, thereby cause whole defective rectifier, generator function is lost.
At present, existing automobile current generator is PPS with rectifier bridge support basic material, 4.5 millimeters of thickness.Adopt the injection mo(u)lding of high temperature mould, profile is that semicircle is irregularly shaped, has three place's rectifier pilot holes (connecting rectifier and end cap fastening) above, the screwed hole of three place's lock cover caps, six place's welding diode pin configurations, six place's stator wire connection structure, everywhere phase terminal pin configurations.This product is used PPS material, has certain intensity and rigidity, need injection moulding nut, otherwise PPS material is too crisp in the screwed hole of lock cover cap, and screw rod is tightened and locking position can be cracked, and loses fastening effect; After PPS material at high temperature, still have contraction, after Product Assembly can because product shrink cause fastening loosening and cause that rectifier diode high temperature burns out, thereby cause automobile current generator afunction, vehicle can not normally travel.
Summary of the invention
The utility model main purpose is to overcome above-mentioned deficiency, and a kind of automobile current generator rectifier bridge support is provided.This support matrix adopting PA66 material, fastening part adopt BMC material, during moulding, without carrying out imbedding of copper nut, greatly reduce cost.
The purpose of this utility model is achieved in that a kind of automobile current generator rectifier bridge support, comprise support, rectifier pilot hole, lock cover cap screwed hole, welding diode pin configuration, stator wire connection structure, phase terminal pin configuration, profile is that semicircle is irregularly shaped, is provided with the screwed hole, six place's welding diode pin configurations, six place's stator wire connection structures of three place's rectifier pilot holes, three places locks cover caps, phase terminal pin configuration everywhere above; It is characterized in that: in rectifier pilot hole, be provided with insulation cushion, lock cover cap screwed hole is not containing the screwed hole of nut, is provided with insulation cushion, during moulding in lock cover cap screwed hole, insulation cushion is contained in rectifier pilot hole and locks in cover cap screwed hole with the form embedding, and carries out injection mo(u)lding.
Described insulation cushion adopts BMC material to make.After injection mo(u)lding, insulation cushion bosom position is provided with rectifier pilot hole and locks the supporting through hole of cover cap screwed hole, and the outside middle part of insulation cushion is provided with the anticreep muscle of circular protrusion, and this anticreep muscle has limited insulation cushion moving up and down in product.In the above and below of anticreep muscle, be respectively provided with three anti-convulsions (amounting to six), this anti-convulsion has limited the rotation of insulation cushion in product.
Described rectifier bridge support matrix adopting PA66 material is made,
The utility model compared with prior art has the following advantages:
1, first, in rectifier pilot hole and in lock cover cap screwed hole, be provided with insulation cushion, this insulation cushion material adopts the injection mo(u)lding of BMC material, and insulation cushion is designed to the structure of anti-rotation, anticreep, avoids with nut rotation, causing inefficacy in fastening process; And BMC material stiffness is fine, Material shrinkage is very little.Thereby the fastening effect that has greatly increased this bridge bracket and end cap, has promoted product stability greatly.
Secondly, this rectifier can be subject to the effect of some external force in fastening process, the excellent in toughness of PA66 material can effectively fall stress concentration or material stiffness product that is too strong and that cause ftractures or the bad appearance of rupturing, at support and end cap, exist after fastening without rigidity stress, product in use can be more stable.This kind of structure effectively avoided occurring because fastening deficiency causes the actual effect of rectifier diode or motor.
When 2, the rectifier bridge support matrix adopting PA66 of new construction, fastening part adopt BMC material, moulding without carrying out imbedding of copper nut, compare with whole use PPS before, guaranteeing that under the better prerequisite of loose fastening function, material cost has reduced by 55%, also greatly reduce man-hour.
