Description

Technical Field

[0001] This utility model relates to the field of high-current connector technology, specifically a partition structure for a high-current connector. Background Technology

[0002] As the application fields of electrical connectors continue to expand, electrical connectors are also being used in some high-power applications that require the transmission of large currents to realize the connection and disconnection of electrical circuits. This has led to the emergence of high-current electrical connectors, which are widely used in electric vehicles, electric forklifts, UPS, general power supplies, medical equipment, solar energy and new energy fields.

[0003] Currently, high-current connectors mostly operate in connection devices with high operating voltages. During long-term use, they often encounter situations where the voltage suddenly increases. Over time, cross-current can occur between the connector terminals, causing damage to the connector and making it unable to withstand high operating voltages. Therefore, this utility model provides a barrier structure for high-current connectors to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a barrier structure for a high-current connector, which at least solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A partition structure for a high-current connector includes a male connector and a female connector, wherein the female connector can be mated and connected in series with the male connector, and a circuit board is fixedly inserted at the bottom of both the male connector and the female connector, and a partition is provided inside the male connector and the female connector.

[0006] As a further embodiment of this utility model, a low-power terminal is fixedly inserted into one side of the male connector and the female connector, and a high-power terminal is fixedly inserted into the other side of the male connector and the female connector. A signal terminal is provided between the low-power terminal and the high-power terminal.

[0007] As a further embodiment of this utility model, guide boxes are fixedly connected to both sides of the upper surface of the male connector, and guide posts are fixedly connected to both sides of the upper surface of the female connector.

[0008] As a further embodiment of this utility model, the male connector has a groove at the upper contact point between the high-power terminal and the male connector, and multiple slots are provided on one side of the groove. The upper position of the high-power terminal has a boss corresponding to the groove, and the right side of the boss has a protrusion corresponding to the slot. The boss and the protrusion can be engaged inside.

[0009] As a further embodiment of this utility model, a limiting arm is provided at the upper end of the signal terminal, and a slot is provided inside the male connector corresponding to the limiting arm to engage with the limiting arm.

[0010] As a further improvement of this utility model, the connector is provided with partitions inserted at the ends of low-power terminals, high-power terminals and signal terminals.

[0011] As a further embodiment of this utility model, the high-power terminal has a long and short lever arm structure, with the contact points of the long and short lever arms distributed vertically. During assembly and insertion, the contact points of the long lever arms make contact first, and the contact points of the short lever arms make contact later.

[0012] As a further embodiment of this utility model, the upper surface of the male connector is provided with a backing groove, and the front end of the low-power terminal is fixedly connected with a terminal backing arm, which can be engaged with the backing groove of the male connector.

[0013] As a further embodiment of this utility model, each of the high-power terminals is fixedly connected to a positioning boss, and the inner sides of both the male and female connectors are provided with grooves that engage with the positioning bosses.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. When this utility model is used, the groove and limiting arm structure make the boss of the terminal engage inside the groove, avoiding excessive gap between the terminal and the plastic body of the connector and causing movement. After the limiting arm is assembled with the male connector, the arm rebounds and restricts the signal terminal from moving back, providing a holding force between it and the plastic body of the connector.

[0015] 2. When this utility model is used, the male terminal can be protected by the set partition, which can effectively avoid the risk of terminal breakage. The partition is composed of multiple rectangular plates arranged at equal distances. This design can strengthen the overall connector structure and increase the creepage distance, allowing the connector to withstand a larger working voltage. Attached Figure Description

[0026] To address the problem of this situation, this utility model provides a partition structure for a high-current connector.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 This utility model provides a partition structure for a high-current connector, including a male connector 1 and a female connector 2. The female connector 2 can be connected in series with the male connector 1. A circuit board 3 is fixedly inserted into the bottom of the metal terminals of both the male connector 1 and the female connector 2. A partition 7 is provided inside the male connector 1 and the female connector 2.

[0029] Both the male connector 1 and the female connector 2 have internal spaces to accommodate the various components of the connector. One end of the female connector 2 can be plugged into the male connector 1 to achieve communication between the connectors. The circuit board 3 at the lower end of the male connector 1 and the female connector 2 is mainly used for the transmission of current and signals of the connector.

[0030] Please refer to Figure 2 In some embodiments, a low-power terminal 4 is fixedly inserted into one side of the male connector 1 and the female connector 2, and a high-power terminal 6 is fixedly inserted into the other side of the male connector 1 and the female connector 2. A signal terminal 5 is provided between the low-power terminal 4 and the high-power terminal 6.

[0031] In this embodiment, the low-power terminal 4, high-power terminal 6 and signal terminal 5 inside the male connector 1 and the female connector 2 have the same structure, and their internal positions and connection relationships are the same. Therefore, in this embodiment, the internal relationship and function of the male connector 1 can also represent the function of the terminals in the female connector 2. The circuit board 3 has multiple holes on its surface. The lower ends of the low-power terminal 4, signal terminal 5 and high-power terminal 6 are fixedly connected to guide pins, which are all fixedly inserted into the holes of the circuit board 3.

[0032] Please see Figure 2-3 In some embodiments, guide boxes 101 are fixedly connected to both sides of the upper surface of the male connector 1, and guide posts 21 are fixedly connected to both sides of the upper surface of the female connector 2.

[0033] One end of the guide box 101 has an opening design, and a cylindrical guide hole is opened in the middle of the connecting box 101 and extends to the bottom of the connecting box 101. A sliding groove is opened below the storage slot and connects to the male connector 1 below. The guide post 21 is a cylindrical guide post with a rectangular block fixedly connected to the lower end of the guide post 21. The front end of the guide post 21 has a rounded corner design. When the male connector 1 and the female connector 2 are mated, the rounded corner design of the guide post 21 allows the guide post 21 to slide into the guide hole of the connecting box 101 more quickly and conveniently during insertion, making it easier for the female connector 2 to be correctly aligned with the male connector 1. The rectangular block at the lower end of the guide post 21 also slides into the sliding groove opened at the lower end of the connecting box 101, which plays a role in assisting in the connection of the male connector 1 and the female connector 2.

[0034] In some embodiments, the upper surface of the male connector 1 is provided with a backstop groove 104, and the front end of the low power terminal 4 is fixedly connected with a terminal backstop arm 41, which can be engaged with the backstop groove 104 of the male connector 1.

[0035] In some embodiments, the sides of the high-power terminals 6 are fixedly connected with positioning bosses 61, and the inner sides of the male connector 1 and the female connector 2 are provided with grooves 22 that engage with the positioning bosses 61.

[0036] Please see Figure 4-5 In some embodiments, the male connector 1 has a groove 102 at the upper part of the contact point between the high power terminal 6 and the male connector 1. A plurality of slots 103 are provided on one side of the groove 102. A boss is provided at the upper part of the high power terminal 6 corresponding to the groove 102. A protrusion is provided on the right side of the boss corresponding to the slots 103. The boss and the protrusion can be engaged inside.

[0037] The groove 102 is designed so that the protrusion of the high-power terminal 6 is engaged inside the groove 102, which prevents the high-power terminal 6 from moving due to excessive assembly gap between it and the male connector 1. The protrusion is provided and the main body is press-fitted with the double slot 103 so that the male connector 1 and the high-power terminal 6 remain fixed.

[0038] Please see Figure 6 In some embodiments, a limiting arm 501 is provided at the upper end of the signal terminal 5.

[0039] The limiting arm 501 has a slot inside the male connector corresponding to the position of the limiting arm 501, which can be snapped into the limiting arm 501. The limiting arm 501 is a plastic elastic arm. After the elastic arm is assembled with the male connector 1, the arm rebounds and restricts the signal terminal from moving back, providing a holding force between it and the plastic body of the male connector 1.

[0040] Please see Figure 7 The male connector 1 has a low-power terminal 4, a high-power terminal 6, and a signal terminal 5, the ends of which are all fitted with partitions 7.

[0041] The barrier 7 protects the male terminal when the male and female connectors are mated, effectively avoiding the risk of terminal breakage. The barrier is composed of multiple rectangular plates arranged at equal intervals, and the surface of the rectangular plates has multiple grooves. This design can strengthen the overall connector structure and increase the creepage distance, allowing the connector to withstand a higher operating voltage.

[0042] Please see Figure 9 The high-power terminal 6 has a long and short lever arm structure. The contact points of the long and short lever arms are distributed vertically. During assembly and insertion, the contact points of the long lever arms make contact first, and the contact points of the short lever arms make contact later. There can be a time difference in the contact sequence, thereby reducing the insertion force.

[0043] When using this utility model, the male connector 1 is connected to the female connector 2. The connection box 101 and guide post 21 can guide the connection process, making it easier for the male connector to connect to the female connector more quickly. When assembling the male connector, the groove and slot inside the male connector 1 can limit and fix the terminals inside. At the same time, the partition inserted at the lower end of the terminal can protect the terminal and increase the creepage distance.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
