Abstract
Disclosed is an input terminal of an automobile rectifier which belongs to the automobile rectifier. Square nuts are put into the four input terminals of the rectifier; a down-lead inlay piece is a purple sheet copper, including a positive diode down-lead of a positive diode and a negative diode down-lead of a negative diode connected by spot welding. When the structure of the input terminal of the automobile rectifier, the four input terminals and a stator coil are connected with bolts, the torsional strength of the M4 square nuts are improved prominently. If the screw loose of the M4 square nuts appears, the square nuts can be taken out and replaced at any time. The whole rectifier will not be discarded due to a screw thread problem. The purple sheet copper is softer and better in conductivity than a cold-roll steel sheet; the stress produced after the expansion of the heated parts and components of the rectifier concentrates on the diode down-lead and the purple sheet copper; because the purple sheet copper is thinner and softer and has good flexibility, the purple sheet copper can absorb and relieve the stress concentrating on the diode down-lead, avoid the down-lead rupturing due to too large stress.
Description
Technical field
The utility model relates to the input end structure of a kind of auto rectifier, particularly a kind of auto rectifier.
Background technology
At present, existing auto rectifier all adopts Japan electric coating series rectifier, the overall structure of this rectifier is semicircle, support (1), positive plate (2) and negative plate (9) are arranged, support, positive plate and negative plate are by rivet (3) riveted joint, there is the base of four positive diodes (5) to be installed on the positive plate, the base of four negative diodes (6) is installed on the negative plate, the positive diode lead (7) of four positive diodes and the lead-in wire (8) of four negative diodes all are connected with support (1), and four nut iron mold inserts (4) input is arranged on the circumference of rectifier.Four nut iron mold inserts (4) input all adopts cold-rolled steel sheet flange screwed hole and the bolt generator unit stator line that is connected, invar plate flange hole tapping is manual operations, the q﹠r of screw thread is wayward, the assembling generator is often because this screw strength deficiency and stripped thread, thereby cause whole rectifier to be scrapped, lose bigger; The lead-in wire of eight diodes on the rectifier is connected with lead-in wire mold insert (10) spot welding on the support, the material of lead-in wire mold insert is a cold-rolled steel sheet, 1.5 millimeters of thickness, eight diode leads on the rectifier form rigidity with lead-in wire mold insert point postwelding and are connected, when working, rectifier can produce high temperature on automobile, the stress that produces behind the parts expanded by heating concentrates on the lead-in wire mold insert of diode lead and steel plate, because of the diode lead material is a red copper, diameter is φ 1.4, its tensile strength is far below the lead-in wire mold insert of steel plate, so often cause the wire breaking of diode, thereby cause whole rectifier to be scrapped.
Summary of the invention
The purpose of this utility model is to provide a kind of screw thread that assembles to be difficult for the not input end structure of the auto rectifier of easy fracture of stripped thread, diode lead.
The purpose of this utility model is achieved in that in four inputs of rectifier puts into square nut; The lead-in wire mold insert is a copper sheet, coats the positive diode lead of a positive diode and the negative diode lead-in wire and the spot welding of a negative diode and is connected.
Beneficial effect: owing to adopt such scheme, put into four M4 square nuts when assembling in four inputs of rectifier, four square nuts can be changed, and because of the M4 square nut is machining in batches, q﹠r easily guarantees, is difficult for stripped thread during assembling; Adopt 0.6 millimeter copper sheet as the lead-in wire mold insert, coat eight diode leads of rectifier and spot welding and connect, the lead-in wire of lead-in wire mold insert and diode is red copper, and the stress that expands with heat and contract with cold equates that diode lead is easy fracture not, has reached the purpose of this utility model.The input end structure of this auto rectifier, when four inputs of rectifier are connected with bolt with the generator unit stator line, the torsional strength of M4 square nut is significantly increased, if the accidental situation that the sliding tooth of M4 square nut is arranged, can take out square nut at any time and change, needn't scrap because of a screw junction causes whole rectifier; Because copper sheet is softer and electric conductivity is better than cold-rolled steel sheet, the stress that produces behind the rectifier parts expanded by heating concentrates on diode lead and the copper sheet, thin softer and have a good flexible because of copper sheet, copper sheet just can be out of shape to absorb by slight bending alleviates the stress that concentrates on the diode lead, avoids lead-in wire because of excessive fracture that meet with stresses.

Embodiment
Embodiment 1: the overall structure of this rectifier is semicircle, support 1, positive plate 2 and negative plate 9 are arranged, support, positive plate and negative plate are by rivet 3 riveted joints, there is the base of four positive diodes 5 to be installed on the positive plate, the base of four negative diodes 6 is installed on the negative plate, the positive diode lead 7 of four positive diodes all is connected with support 1 with the lead-in wire 8 of four negative diodes, and four inputs are arranged on the circumference of rectifier.
In four inputs of rectifier, put into square nut 18; Lead-in wire mold insert 12 is a copper sheet, and the lead-in wire mold insert adopts 0.6 millimeter copper sheet to make, and the lead-in wire mold insert coats the positive diode lead 7 of a positive diode 5 and the negative diode lead-in wire 8 and the spot welding of a negative diode 6 is connected.
Claims (1)
1, a kind of input end structure of auto rectifier is characterized in that: put into square nut in four inputs of rectifier; The lead-in wire mold insert is a copper sheet, coats the positive diode lead of a positive diode and the negative diode lead-in wire and the spot welding of a negative diode and is connected.
