[0024] The specific implementation of the present invention will be further explained in detail below by describing the best embodiment with reference to the accompanying drawings.

[0025] The rectifier bridge body involved in the present invention is connected to the stator leads and the rectifier bridge diode leads through the rectifier bridge terminals. For the sake of convenience, the stator leads and the rectifier bridge diode leads are collectively referred to as leads below.

[0026] A rectifier bridge structure includes a rectifier bridge body 1; the rectifier bridge body 1 is provided with a plurality of rectifier bridge terminals; the rectifier bridge terminals include copper wire terminals 2 connected to the rectifier bridge body 1; the present invention discloses a rectifier bridge structure, which optimizes the rectifier bridge terminals and uses copper wires instead of the original copper plate structure to facilitate the arrangement of the rectifier bridge terminals; and can significantly reduce the production cost of the rectifier bridge.

[0027] Preferably, the copper wire terminal 2 in the present invention includes at least two single copper wires 21; adjacent single copper wires 21 are spaced apart; one end of each single copper wire 21 is connected to the rectifier bridge body 1; the single copper wire 21 in the present invention plays a connecting role. In actual use, each copper wire terminal 2 includes two single copper wires 21, and the two single copper wires 21 are spaced apart; the spaced-apart single copper wires 21 play a good supporting role; in subsequent connection, the copper wire terminal 2 is connected to the lead through a tin welding process, which can reduce the use of copper and save production costs; the two single copper wires are set to play a role of limiting position. In subsequent connection, the two adjacent single copper wires are connected to each other to ensure the strength of the copper wire terminal.

[0028] In addition, as a greater optimization, each of the single copper wires 21 in the present invention includes a longitudinal copper wire 211 and a layer of transverse copper wire 212; the layer of transverse copper wire 212 is connected to the rectifier bridge body 1 through the longitudinal copper wire 211; the longitudinal copper wire 211 plays a good role in raising the height, and a layer of transverse copper wire 212 is provided at the end of the longitudinal copper wire 211; the layer of transverse copper wire 212 plays a supporting role, and the layer of transverse copper wire 212 plays a basic connection role, which is convenient for the connection between the copper wire terminal 2 and the lead; a plurality of groove structures can be set on the layer of transverse copper wire for easy positioning, and an arc groove 2-1 for positioning is provided on the layer of transverse copper wire, and the depth of the arc groove 2-1 is less than the radius of the lead, so that the lead can be exposed, which is convenient for the subsequent two layers of transverse copper wires to squeeze and fix the lead; in addition, as a greater optimization, the two layers of transverse copper wires of the present invention are provided with an extrusion protrusion 2-2, and the extrusion protrusion 2-2 cooperates with the arc groove 2- 1. The leads placed in the second layer of horizontal copper wire and the first layer of horizontal copper wire are squeezed to facilitate the fixation of the leads. In addition, the squeezing protrusion 2-2 has a limiting effect to avoid lateral movement of the leads. The arc groove 2-1 and the squeezing protrusion 2-2 in the present invention are spaced apart, and the arc groove 2-1 and the squeezing protrusion 2-2 in the present invention are spaced apart. From the top view, it is required that at least one squeezing protrusion 2-2 is distributed on both sides of each arc groove 2-1. Such an arrangement ensures that both sides of the leads in each arc groove 2-1 are limited anyway, thereby better avoiding excessive lateral movement of the leads. In addition, as a greater optimization, an squeezing horizontal plate 2-3 is provided between adjacent squeezing protrusions 2-2 in the present invention. The squeezing horizontal plate 2-3 corresponds to the arc groove 2-1, and the squeezing horizontal plate 2-3 assists in squeezing the leads to avoid affecting the pressing effect of the second layer of horizontal copper wire on the leads due to the presence of the squeezing protrusion 2-2.

[0029] Preferably, the longitudinal copper wire 211 described in the present invention is arranged perpendicular to a layer of transverse copper wire 212; such an arrangement enables a platform structure to appear on the upper end of the copper wire terminal 2, which is convenient for positioning and connection with the lead; and facilitates subsequent arrangement. As a greater optimization, the layer of transverse copper wire 212 described in the present invention is arranged parallel to the upper end face of the rectifier bridge body 1; through such an arrangement, after the rectifier bridge is installed, the layer of transverse copper wire 212 is also equivalent to a transverse arrangement, which facilitates subsequent welding.

[0030] Preferably, the longitudinal copper wire 211 in the present invention is connected to the rectifier bridge body 1 through a transition copper wire 213; the transition copper wire 213 has an arc-shaped structure. Such a setting can make the copper wire terminal 2 more smoothly connected to the side of the rectifier bridge body 1; at the same time, a certain gap is created between the longitudinal copper wire and the rectifier bridge body, which facilitates the arrangement of the longitudinal copper wire and the rectifier bridge body and avoids subsequent installation interference problems.

[0031] Preferably, the single copper wire 21 in the present invention further includes two layers of transverse copper wires 214; the two layers of transverse copper wires 214 are located above the first layer of transverse copper wires 212; the two layers of transverse copper wires 214 are spaced apart from the first layer of transverse copper wires 212; the two layers of transverse copper wires 214 are connected to the first layer of transverse copper wires 212 via connecting copper wires 215; the two layers of transverse copper wires 214 and the first layer of transverse copper wires 212 are spaced apart from each other, with a certain gap between them, which can be used to place leads and serves to position the leads. In addition, by modifying the size of the gap, the gap and the leads can be transitionally matched, so that the gap exerts an extrusion force on the leads, thereby having a good limiting effect on the leads and facilitating subsequent fixation; in the present invention, the two layers of transverse copper wires can be arranged to intersect with the first layer of transverse copper wires, where intersecting means that the free ends of the two layers of transverse copper wires extend toward the first layer of transverse copper wires; such an arrangement enables the two layers of transverse copper wires and the first layer of transverse copper wires to have an open side, and the opening is reduced, which can reduce or prevent the leads from falling off laterally.

[0032] Preferably, in the present invention, after the leads are placed on a layer of transverse copper wires, the second layer of transverse copper wires can be moved toward the first layer of transverse copper wires manually or by applying external force, which can better ensure the stability of the lead placement.

[0033] Preferably, the length of the first layer of transverse copper wire 212 in the present invention is greater than that of the second layer of transverse copper wire 214. This arrangement allows the lower end to support a larger range of leads, because the first layer of transverse copper wire 212 is the main connection device in the present invention, and the second layer of transverse copper wire 214 only serves as a preliminary positioning function. Therefore, the present invention adopts a first layer of transverse copper wire 212 having a length greater than that of the second layer of transverse copper wire 214, which can at least ensure the contact area when the lead is connected to the first layer of transverse copper wire 212, thereby ensuring the stability of the connection between the lead and the copper wire terminal 2 during subsequent welding.

[0034] Preferably, the vertical cross-section of the connecting copper wire 215 in the present invention is arc-shaped; the protruding part of the connecting copper wire 215 is facing away from the first layer of horizontal copper wire 212 and the second layer of horizontal copper wire 214. One aspect of setting the connecting copper wire 215 is to realize the connection between the first layer of horizontal copper wire 212 and the second layer of horizontal copper wire 214. In addition, because the connecting copper wire 215 is an arc-shaped structure, it can play a role in increasing the position for placing the lead; in addition, by setting the connecting copper wire 215, the second layer of horizontal copper wire 214 can be made equivalent to a suspended setting, which can facilitate the opening of the second layer of horizontal copper wire 214; facilitate the placement of the lead, and also facilitate the subsequent deformation of the second layer of horizontal copper wire.

[0035] Preferably, in the present invention, two adjacent single copper wires 21 are connected by a transverse arc-shaped copper wire 216; the transverse arc-shaped copper wire 216 serves to connect the two adjacent single copper wires 21, thereby making the two single copper wires 21 more integrated and better ensuring the structural strength of the copper wire joint; in addition, as a greater optimization, the transverse arc-shaped copper wire 216 in the present invention is connected to the end of the adjacent two-layer transverse copper wire 214; the arrangement of the transverse arc-shaped copper wire 216 here enables a direct connection between the two single terminals, thereby ensuring the overall structural strength of the copper wire terminal 2. At the same time, the transverse arc-shaped copper wire 216 adopts such an arrangement position, which does not affect the opening of the two-layer transverse copper wire 214, thereby better achieving the above-mentioned purpose.

[0036] In addition, as a greater optimization, the transverse arc copper wire in the present invention can be arranged obliquely relative to the second layer of transverse copper wires, so that the end of the second layer of transverse copper wire has a limiting point, which plays a better limiting and protective role.

[0037] In addition, as a greater optimization, when the rectifier bridge terminal is connected to the lead in the present invention, the lead and the rectifier bridge terminal are connected by first clamping the lead and the rectifier bridge terminal, and then welding the rectifier bridge terminal and the lead after the clamping is fixed. This method is convenient for positioning and actual connection.

[0038] In addition, in order to facilitate deformation, the thickness of the connecting copper wire in the present invention can be half the diameter of the first layer of horizontal copper wire; this not only saves the use of copper wire, but also facilitates subsequent deformation and the opening and closing of the second layer of horizontal copper wire.

[0039] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the scope of protection of the present invention.
