Description

Rectifier for generator

Technical Field

The utility model relates to the technical field of automobiles, in particular to a rectifier for a generator.

Background

In automobiles, an alternator is the primary power source for the automobile and is driven by the engine. An alternator is generally composed of components such as a rectifier, a stator, a rotor, and an end cover. In an alternator, a rectifier functions to convert three-phase alternating current of a stator into direct current.

Generally, a rectifier for an automotive alternator is composed of a positive current plate, a negative current plate, a connecting plate disposed between the positive current plate and the negative current plate, and a lead wire of a negative diode on the negative current plate and a connecting wire of the connecting plate are connected by welding. However, since the bonding pad between the connection wire of the connection board and the lead wire of the negative diode is close to the fixing point of the lead wire of the negative diode, and the connection wire of the connection board is generally strong, the lead wire of the negative diode is easily damaged by a large stress at the bonding point during vibration.

An embodiment of the present invention discloses a rectifier 10 for an automotive generator. As shown in fig. 1 and 2, the rectifier 10 according to the embodiment of the present invention includes a positive current plate 130, a negative current plate 110, and a connection plate 120. The connection plate 120 is disposed between the positive current plate 130 and the negative current plate 110. Specifically, the connection plate 120 is located above the negative current plate 110 and connected to the negative current plate 110, and the positive current plate 130 is located above the connection plate 120 and connected to the connection plate 120. The connection plate 120 includes a main body 126 and a first connection ring 1221 extending outward from the main body 126, a distal end of the first connection ring 1221 is bent toward a proximal end thereof to a side of the proximal end facing the positive current plate 130 (e.g., above the proximal end as shown in fig. 1) and parallel to the proximal end, and the distal end of the first connection ring 1221 is connected to a lead of the negative diode 1101 provided on the negative current plate 110, for example, by soldering.

Here, it should be noted that the distal end and the proximal end of the first connection ring 1221 are relative to the main body 126, and since the first connection ring 1221 extends outward from the main body 126, the distal end of the first connection ring 1221 is the end far from the main body 126, and the proximal end of the first connection ring 1221 is the end connected to the main body 126.

In the rectifier 10 according to the embodiment of the utility model, the distal end of the first connection ring 1221 of the connection plate 120 is bent toward the proximal end thereof to the side facing the positive current plate 130 at the proximal end and parallel to the proximal end, and is connected to the lead bonding of the negative diode 1101 provided on the negative current plate 110. Thereby, the distance between the bonding point between the first connection ring 1221 and the lead of the negative diode 1101 and the fixing point of the lead of the negative diode 1101 is increased compared to the first connection ring that is not bent in the related art. In addition, the bent first connection ring 1221 has a bent portion, and the bent portion can play a role of buffering. Therefore, the stress at the welding point is significantly reduced, thereby avoiding the lead of the negative diode 1101 from being damaged at the welding point during vibration.

Specifically, as shown in fig. 4 and 5, the first connection ring 1221 includes a first section 12211 and a second section 12212 and a bent section 12213 connected therebetween. The first section 12211 extends outward from the body 126 and includes a proximal end of the first connection ring 1221, the second section 12212 is located on a side of the first section 12211 facing the positive current plate 130 (e.g., above the first section 12211) and parallel to the first section 12211, the second section 12212 includes a distal end of the first connection ring 1221, and the bent section 12213 is smoothly connected to the first section 12211 and the second section 12212. The second section 12212 is connected to the lead of the negative diode 1101, for example, by soldering.

In contrast to the unbent first connection ring 1221 of the prior art, the second segment 12212 of the present invention is connected to the lead of the negative diode 1101, rather than the first segment 12211 being directly connected to the lead of the negative diode 1101. Since the second section 12212 is located on the side of the first section 12211 facing the positive current plate 130, that is, the side facing away from the negative current plate 110, the distance between the second section 12212 and the fixing point of the lead of the negative diode 1101 is greater than the distance between the first section 12211 and the fixing point of the lead of the negative diode 1101, so that the stress at the welding point of the first connection ring 1221 and the lead of the negative diode 1101 can be significantly reduced. Further, stress at the welding point of the first connection ring 1221 and the lead wire of the negative diode 1101 can be further reduced due to the buffer action of the bent section 12213 connected between the first section 12211 and the second section 12212 on the second section 12212. Thereby, the lead of the negative diode 1101 is prevented from being damaged at the welding point due to a large stress at the welding point during vibration.

Further, as shown in fig. 3 to 7, the connection plate 120 includes a first connection portion 121 and a second connection portion 122 disposed on the body 126 and adjacent to each other. The first connection part 121 connects the negative current plate 110, the connection plate 120, and the positive current plate 130 to each other. The second connection portion 122 includes the above-described first connection ring 1221, and further includes a third connection ring 1223, the third connection ring 1223 being connected with a stator lead (not shown) of the generator, and the first connection portion 121 being disposed adjacent to the third connection ring 1223. Specifically, the stator lead extends upward into the third connection ring 1223, and is welded to the third connection ring 1223.

Further, as shown in fig. 3, the third connection ring 1223 includes a base 12231 and a ring 12232, the base 12231 is integrally formed with the main body 126 and the first connection portion 121 of the connection plate 120, and the ring 12232 protrudes from the base 12231 and is connected to the stator lead of the generator, for example, by welding. The collar 12232 is constructed as a unitary member. For example, the main body 126 is formed as an integral plastic piece from a plastic material with the first connection portion 121 and the base portion 12231, while the ring portion 12232 is formed as an integral copper ring from copper wire.

In some embodiments of the utility model, the rectifier 10 may be disposed at one end of a stator (not shown) and the negative rectifier plate 110 is configured as at least a portion of an end cap of the stator at that end. In this way, the number of parts of the generator can be reduced, the assembly process of the generator is simplified, and the manufacturing cost of the generator is reduced.

In addition, the positive current plate 130 is also configured as a heat radiation plate for radiating heat to the positive diode provided thereon, thereby further reducing the number of parts of the generator and reducing the manufacturing cost of the generator.

In some embodiments of the present invention, as shown in fig. 1-3, the positive rectifier plate 130 is provided with a positive diode 1301 and the negative rectifier plate 110 is provided with a negative diode 1101. The positive diode 1301 can be directly press-fitted to the positive rectifying plate 130. For example, the positive rectifying plate 130 is provided with a mounting hole, and the positive diode 1301 is inserted into the mounting hole. Similarly, the negative diode 1101 may be directly press-fitted to the negative rectification plate 110. For example, the negative rectifying plate 110 is provided with a mounting hole, and the negative diode 1101 is inserted in the mounting hole.

Further, as shown in fig. 3 to 7, the second connection portion 122 further includes a second connection ring 1222, and the second connection ring 1222 is connected to the positive diode 1301. Specifically, the lead of the positive diode 1301 extends downward into the second connection ring 1222 and is soldered to the second connection ring 1222, while the lead of the negative diode 1101 extends upward into the first connection ring 1221 and is soldered to the first connection ring 1221.

In this way, the lead wire of the positive diode 1301, the lead wire of the negative diode 1101, and the stator lead wire are connected to the same connection board 120, so that an operator can install the lead wires in place with the connection board 120 at a time during the installation process, thereby improving the installation efficiency.

In some embodiments of the present invention, as shown in fig. 3 to 5, the first connection portion 121 further has a pillar 1212 protruding downward from a lower surface thereof, and the negative fairing 110 has a receiving hole (not shown) corresponding to the pillar 1212, and the pillar 1212 is adapted to be inserted into the receiving hole, thereby further ensuring the firmness and stability of the connection between the negative fairing 110 and the connection plate 120. In addition, the upright 1212 plays a certain supporting role, and increases the overall rigidity of the connecting plate 120, so as to further reduce the transmission of vibration to other welding points, and further reduce the working stress of other welding points.

Specifically, since the stator leads are connected to the connection plate 120 by welding, the stator vibrates during operation, dragging the connection plate 120 to vibrate together, but the support effect of the post 1212 may reduce the vibration transmission, thereby protecting the welded connection between each connection ring and the corresponding lead.

In some embodiments of the present invention, as shown in fig. 4-7, the first connection portion 121 and the second connection portion 122 are disposed at an edge of the body 126 of the connection plate 120, the first connection portion 121, the third connection ring 1223, and the first connection ring 1221 are located outside the edge of the body 126 of the connection plate 120, and the second connection ring 1222 is located inside the edge of the body 126 of the connection plate 120. Specifically, the body 126 of the connection plate 120 may be an arc-shaped plate, the first connection portion 121, the third connection ring 1223, and the first connection ring 1221 being disposed outside a circumference of the arc-shaped plate, and the second connection ring 1222 being disposed inside the circumference of the arc-shaped plate. Thus, the first connection portion 121, the third connection ring 1223, the second connection ring 1222, and the first connection ring 1221 are disposed on the same arc-shaped plate (i.e., the main body 126 of the connection plate 120) at a proper position so that the connection plate 120 can be connected to the stator lead, the lead of the positive diode 1301, and the lead of the negative diode 1101 at the same time.

In addition, the position where the negative diode 1101 is provided on the negative current plate 110 corresponds to the position of the first connection ring 1221, the position where the positive diode 1301 is provided on the positive current plate 130 corresponds to the position of the second connection ring 1222, and the lead-out position of the stator lead also corresponds to the position of the third connection ring 1223. Thereby, the stator lead, the positive diode 1301, and the negative diode 1101 can be simultaneously connected to the third connection ring 1223, the second connection ring 1222, and the first connection ring 1221, respectively.

In some embodiments of the present invention, as shown in fig. 4 and 5, the connection plate 120 has a hollow 123 inside the edge of the body 126, and the second connection ring 1222 is located inside the hollow 123. When the positive current plate 130 is assembled with the connection plate 120, the positive diode 1301 is also positioned within the hollow portion 123, thereby securing connection stability between the second connection ring 1222 and the positive diode 1301 while securing structural strength of the connection plate 120.

Specifically, the hollow 123 is surrounded by a semi-annular member protruding inward from the inside of the edge of the main body 126 of the connection plate 120, and the second connection ring 1222 also protrudes inward from the inside of the edge of the main body 126 of the connection plate 120, first extending downward and then extending inward, whereby the second connection ring 1222 has a vertical portion and a horizontal portion, and the horizontal portion is located below the hollow 123. When the positive current plate 130 is assembled with the connection plate 120, a portion of the positive diode 1301 is received in the hollow portion 123, and the horizontal portion of the secondary connection ring 1222 is positioned below the positive diode 1301, and the lead of the positive diode 1301 extends downward, passes through, and is soldered to the horizontal portion of the secondary connection ring 1222. In this way, a stable connection between the positive diode 1301 and the second connection ring 1222 can be further ensured, thereby ensuring operational reliability of the rectifier 10.

As shown in fig. 6 and 7, the connection plate 120 includes a plurality of connection units each including the above-described first connection portion 121 and second connection portion 122. Specifically, the connection plate 120 has three connection units, i.e., a first connection unit and a third connection unit located at both ends of the arc-shaped connection plate 120, and a second connection unit located in the middle of the arc-shaped connection plate 120 (i.e., located between the first connection unit and the third connection unit).

The first connection unit includes a first connection part 121 and a second connection part 122. The second connection portion 122 includes two third connection rings 1223. Both third connecting rings 1223 are constructed as an integral component. Two third connection rings 1223 are respectively located at both sides of the first connection portion 121, and are integrally constructed with the first connection portion 121. The second connecting portion 122 further includes a second connection ring 1222 and a first connection ring 1221. The second connection ring 1222 and the first connection ring 1221 are provided at a side of the first connection part 121 close to the second connection unit (i.e., a right side of the first connection part 121, as shown in fig. 6). The third connection ring 1223, the second connection ring 1222, and the first connection ring 1221 positioned at the right side of the first connection portion 121 are integrally formed and are sequentially disposed. For example, the third connection ring 1223, the second connection ring 1222, and the first connection ring 1221 located at the right side of the first connection portion 121 may be formed of the same copper wire.

The second connection unit includes a first connection part 121 and a second connection part 122. The second connection portion 122 includes two third connection rings 1223. Both third connecting rings 1223 are constructed as an integral component. Two third connection rings 1223 are respectively located at both sides of the first connection portion 121, and are integrally constructed with the first connection portion 121. The second connecting portion 122 further includes a second connection ring 1222 and a first connection ring 1221. The second connection ring 1222 and the first connection ring 1221 are provided at a side of the first connection part 121 close to the third connection unit (i.e., a right side of the first connection part 121, as shown in fig. 6). The third connection ring 1223, the second connection ring 1222, and the first connection ring 1221 located at the right side of the first connection portion 121 are integrally formed. For example, the third connection ring 1223, the second connection ring 1222, and the first connection ring 1221 located at the right side of the first connection portion 121 may be formed of the same copper wire. Further, a third connection ring 1223 located at the right side of the first connection portion 121 is disposed opposite to the second connection ring 1222 and is disposed adjacent to the first connection ring 1221.

In addition, the third connection ring 1223 of the second connection unit, which is located at a side of the first connection unit 121 close to the first connection unit (i.e., the left side of the first connection unit 121, as shown in fig. 6), is integrated with the first connection ring 1221 of the first connection unit. In other words, the third connection ring 1223, the second connection ring 1222, and the first connection ring 1221 of the first connection unit, which are located at the right side of the first connection portion 121 thereof, are integrally formed with the third connection ring 1223 of the second connection unit, which is located at the left side of the first connection portion 121 thereof, for example, by the same copper wire.

The third connection unit includes a first connection part 121 and a second connection part 122. The second connection portion 122 includes two third connection rings 1223. A third connection ring 1223 is positioned at a side of the first connection portion 121 adjacent to the second connection unit (i.e., the left side of the first connection portion 121, as shown in fig. 6), and is integrally constructed with the first connection portion 121. The second connecting portion 122 further includes a second connection ring 1222 and a first connection ring 1221. The second connection ring 1222 and the first connection ring 1221 are provided at a side of the third connection ring 1223 adjacent to the second connection unit. The first connection ring 1221 is positioned between the second connection ring 1222 and the above-mentioned third connection ring 1223, and the other third connection ring 1223 is positioned at a side of the second connection ring 1222 adjacent to the second connection unit, i.e., the first connection ring 1221 and the second connection ring 1222 are positioned between the two third connection rings 1223. One third connection ring 1223 (near the first connection portion 121), the second connection ring 1222, and the first connection ring 1221 of the third connection unit are integrally formed, and are integral with the third connection ring 1223 of the first connection unit located at a side of the first connection portion 121 remote from the second connection unit (i.e., a left side of the first connection portion 121, as shown in fig. 6), for example, formed of the same copper wire. Further, another third connection ring 1223 of the third connection unit (remote from the first connection portion 121) is integral with the first connection ring 1221 of the second connection unit. In other words, the third connection ring 1223, the second connection ring 1222, and the first connection ring 1221 of the second connection unit, which are located at the right side of the first connection portion 121 thereof, are integrally formed with another third connection ring 1223 of the third connection unit, for example, by the same copper wire.

It should be noted that those skilled in the art will understand that copper wires should be arranged in the connection plate 120 to integrally form the above-mentioned respective associated third connection ring 1223, second connection ring 1222 and first connection ring 1221. As to the arrangement of the copper wires in the connection plate 120, the present invention does not limit this as long as the respective integral arrangement between the respective connection rings is satisfied.

Further, as described above, the second connection rings 1222 of the first to third connection units are all located inside the edge of the body 126 of the connection plate 120, and the first connection portions 121, the third connection rings 1223, and the first connection rings 1221 are all located outside the edge of the body 126 of the connection plate 120.

In addition, the orientations "left" and "right" in the above description are with respect to FIG. 6. Specifically, in the clockwise direction, the orientation at the downstream is "right", and the orientation at the upstream is "left". Since fig. 6 and 7 are a bottom view and a top view of the connecting plate 120, respectively, the orientations "left" and "right" in fig. 7 are opposite to those in fig. 6, i.e., the orientation "left" in fig. 6 should be the orientation "right" in fig. 7, and the orientation "right" in fig. 6 should be the orientation "left" in fig. 7, with the same definition.

Furthermore, in some embodiments of the present invention, the connection plate 120 further includes an adjuster connection ring 124, and the adjuster connection ring 124 is located at an end of the connection plate 120 where the first connection unit is located. The regulator connection ring 124 may be integrally formed with the third connection ring 1223 of the above-described first connection unit on the left side of the first connection portion 121 thereof, for example, formed of the same copper wire. The regulator attachment ring 124 is adapted to be connected to a regulator (not shown) for regulating the field current of the rotor. It should be noted that the regulator is well known to those skilled in the art and therefore will not be described in detail.

Further, as shown in fig. 6 and 7, the first connection part 121 has a connection hole 1211, and the connection hole 1211 is used to receive a bolt 125 to connect the negative current plate 110, the connection plate 120, and the positive current plate 130 to each other. Accordingly, the positive and negative current plates 130 and 110 have additional connection holes (not shown), respectively, aligned with the connection holes 1211 of the first connection part 121 and adapted to receive the bolts 125 together with the connection holes 1211 of the first connection part 121 to connect the negative current plate 110, the connection plate 120, and the positive current plate 130 to each other. In this way, the connection manner between the negative current plate 110, the connection plate 120, and the positive current plate 130 can be simplified while ensuring the stability of the connection.
