Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, specifically a stacked rectifier bridge. Background Technology

[0002] A rectifier bridge is a common electronic component widely used in power adapters, chargers, home appliances and other electronic products. Its core function is to use the unidirectional conductivity of diodes to conduct the positive and negative half-cycles of alternating current and output direct current. Rectifier bridges generally have a sufficiently large inductive load, so there is no current discontinuity in rectifier bridges.

[0003] Most rectifier bridges currently on the market are manufactured using splicing or docking methods. This requires the various terminals to be laid out, increasing the overall size of the rectifier bridge and the space occupied during installation. Moreover, during use, the pins of the rectifier bridge are fixed. Once they break after welding, the bridge is scrapped, which increases resource waste.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a stacked rectifier bridge to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a package body, with a positive output terminal, a first AC input terminal, a second AC input terminal, and a negative output terminal respectively connected to its four corners. A metal contact is connected to one side of each of the positive, first, second, and negative output terminals. Indicator slots are provided on both sides of the package body. A replaceable mounting mechanism is provided on one side of each of the positive, first, second, and negative output terminals. Two substrates are connected inside the package body, and two diode chips are connected to one side of each substrate.

[0007] Preferably, the metal contacts are located at the center of the package and are arranged vertically.

[0008] Preferably, the bottom inner sides of the two indicator slots are respectively provided with a positive electrode mark and a negative electrode mark.

[0009] Preferably, the two shims are divided into a P-type frame and an N-type frame, and the diode chips on the P-type frame and the N-type frame are electrically connected to the metal contacts.

[0010] Preferably, the bottom of the package has a fitting groove, and the four corners of the package have operation grooves corresponding to the positive output terminal, the first AC input terminal, the second AC input terminal and the negative output terminal.

[0011] Preferably, heat dissipation grooves are provided on both sides of the package, ventilation holes are provided between the heat dissipation grooves, and multiple heat dissipation holes are provided at the top of the ventilation holes.

[0012] Preferably, the replaceable mounting mechanism includes mounting holes formed on one side of the positive output terminal, the first AC input terminal, the second AC input terminal, and the negative output terminal. A bracket is connected to the inside of the mounting hole, and multiple sets of connecting pins are connected to the inside of the mounting hole.

[0013] Preferably, the connecting pins are located between the branches of the bracket.

[0014] Preferably, the connecting pin has a break groove on the side near the edge of the mounting hole.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] By stacking the metal contacts, the overall size of the rectifier bridge is greatly reduced, thus reducing space occupation. The connection relationship between the positive output terminal, the first AC input terminal, the second AC input terminal, the negative output terminal, and the package can be seen. It can be directly and forcefully removed during disassembly. The design of the break-off groove facilitates the breaking of the connecting pins. The remaining connecting pins can meet the needs of reinstallation and are easy to recycle. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: It includes a package 1, with a positive output terminal 2, a first AC input terminal 3, a second AC input terminal 4, and a negative output terminal 5 connected to its four corners. Metal contacts 6 are connected to one side of each of the positive output terminal 2, the first AC input terminal 3, the second AC input terminal 4, and the negative output terminal 5. The metal contacts 6 are located at the center of the package 1 and are arranged vertically, effectively reducing the overall volume of the rectifier bridge and the space occupied during installation. Indicator slots 7 are provided on both sides of the package 1, with positive and negative markings respectively at the bottom of the inner side of the two indicator slots 7. During installation... To facilitate identification and avoid installation errors, replaceable mounting mechanisms are provided on one side of the positive output terminal 2, the first AC input terminal 3, the second AC input terminal 4, and the negative output terminal 5. Two pads 9 are connected inside the package 1. The two pads 9 are divided into P-type frames and N-type frames, and the diode chips 10 on the P-type frames and N-type frames are electrically connected to the metal contact 6, thereby forming an electrical connection between the positive output terminal 2, the first AC input terminal 3, the second AC input terminal 4, and the negative output terminal 5. The connection method is a common technology, so it is not described in detail in the specification. Two diode chips 10 are connected to one side of each pad 9.

[0024] Reference Figure 2 As shown, the bottom of the package 1 is provided with a fitting groove 222. When it is installed on the circuit board, if there are solder points under the package 1, the solder points can be covered so that the package 1 can fit well with the circuit board. The four corners of the package 1 are provided with operation grooves 111 corresponding to the positive output terminal 2, the first AC input terminal 3, the second AC input terminal 4 and the negative output terminal 5, which facilitates installation and operation. The four soldering terminals at different angles can effectively avoid errors during soldering.

[0025] Reference Figure 1 and Figure 2 As shown, heat dissipation grooves 21 are provided on both sides of the package 1, and ventilation holes 22 are provided between the heat dissipation grooves 21. Multiple heat dissipation holes 23 are provided at the top of the ventilation holes 22. Since the multiple holes 23 are close together, the heat will be concentrated. The ventilation holes 22 can form an airflow channel to further carry away the heat. The heat dissipation holes 23 located above will further improve the heat dissipation effect.

[0026] Reference Figure 4 As shown, the replaceable mounting mechanism includes mounting holes 101 on one side of the positive output terminal 2, the first AC input terminal 3, the second AC input terminal 4, and the negative output terminal 5. A bracket 102 is connected to the inside of the mounting hole 101, and multiple sets of connecting pins 103 are connected to the inside of the mounting hole 101. The connecting pins 103 are located between the branches of the bracket 102. During installation, one of the connecting pins 103 can be soldered to the circuit board. The bracket 102 effectively prevents the molten solder from affecting other connecting pins 103. A break groove 104 is provided on the side of the connecting pin 103 near the edge of the mounting hole 101. During disassembly, 103 can be easily removed from the corresponding positive output terminal 2, the first AC input terminal 3, the second AC input terminal 4, and the negative output terminal 5 through 104. The remaining connecting pins 103 can be used for reinstallation.

[0027] The implementation principle of this application is as follows: When using this utility model, the installation position is determined by the positive and negative polarity markings in the indicator slot 7. The positive output terminal 2, the first AC input terminal 3, the second AC input terminal 4 and the negative output terminal 5 are soldered and installed by using a soldering gun or spot welding device. Since the metal contact pieces 6 are stacked vertically, the space occupied on the circuit board can be greatly reduced. At the same time, the heat dissipation effect can be effectively increased through the vent hole 22 and the heat dissipation hole 23 above.
