Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a simple high-current Type-C connector. Background Technology

[0002] High-current Type-C connectors are specially designed USB Type-C interface components capable of transmitting high currents. Compared to traditional Type-C connectors, high-current Type-C connectors are optimized in electrical performance and physical structure to meet the power transmission needs of high-power devices. These connectors can safely transmit higher currents than standard Type-C interfaces. While standard Type-C interfaces typically support a maximum current of 3A, high-current Type-C connectors can support 5A or even higher currents, enabling them to be used to charge high-power devices such as laptops, tablets, and game consoles.

[0003] Current high-current Type-C connectors primarily consist of an insulating body, two rows of terminals, a central clip, and a shielding shell. The insulating body includes a base and a tongue extending from the base. The central clip and the two rows of terminals are embedded in the insulating body, with the central clip positioned between the two rows of terminals. Hooks are formed on both sides of the upper end of the central clip, protruding from the left and right sides of the tongue. The shielding shell covers the insulating body. However, these Type-C connectors have a relatively large number of components, a complex structure, are inconvenient to manufacture and assemble, and are costly. In particular, the large number of terminals prevents them from maximizing the maximum current capacity. Therefore, it is necessary to improve current high-current Type-C connectors. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a simple high-current Type-C connector, which can effectively solve the problem that the existing high-current Type-C connectors have many components, resulting in complex structure and failing to maximize the maximum value of the high current that can be passed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A simple high-current Type-C connector comprises an insulating body, a positive terminal, and a negative housing. The insulating body includes a base and a tongue extending from the base. The positive terminal is embedded and fixed to the insulating body, and has a first positive contact, a second positive contact, and a positive solder pad. The first and second positive contacts are exposed on the two surfaces of the tongue, and the positive solder pad extends beyond the base. The negative housing covers the insulating body, and at least one rear end of the negative housing is integrally formed and bent to extend a negative solder pad and a hook. The negative solder pad is exposed beyond the base, and the front end of the hook abuts against the side of the tongue.

[0007] As a preferred embodiment, the positive terminal is formed by stamping and reversing the bending of a metal plate, and includes two main body parts that are stacked together. The first positive electrode contact part and the second positive electrode contact part extend from the front side of the two main body parts respectively. The rear ends of the two main body parts are integrally formed, bent and connected to form the positive electrode welding foot part.

[0008] As a preferred embodiment, the first positive electrode contact portion and the second positive electrode contact portion are both arranged symmetrically on the left and right. The two first positive electrode contact portions are bent and extended from both sides of the front end of one main body portion, and the two second positive electrode contact portions are bent and extended from both sides of the front end of the other main body portion.

[0009] As a preferred embodiment, wings extend from both sides of the two main bodies, with each wing located behind the first positive electrode contact and the second positive electrode contact, and each wing is embedded in the base.

[0010] As a preferred embodiment, the base has a slot on its side, and the rear end of the hook is embedded in the slot.

[0011] As a preferred embodiment, the left and right rear ends of the negative electrode shell are integrally formed and bent to extend out negative electrode welding feet and hooks, with both negative electrode welding feet protruding from the base, and the front ends of the two hooks respectively abutting against the left and right sides of the tongue plate.

[0012] As a preferred embodiment, the base has slots on both its left and right sides, and the rear ends of the two hooks are respectively embedded in the two slots.

[0013] As a preferred embodiment, the insulating body is vertically arranged, with the two negative electrode solder feet extending horizontally and protruding from the bottom surfaces of the left and right ends of the base, respectively. The positive electrode solder foot extends vertically, located at the center of the base and extending downwards from the bottom surface of the base, so as to be vertically inserted and soldered to the external circuit board, making the connection structure more stable and reliable.

[0014] As a preferred embodiment, the outer surface of the base is recessed with a buckle groove, and the rear edge of the negative electrode shell is bent and extended with a buckle piece. The buckle piece cooperates with the buckle groove to lock and fix the structure, which is simple and easy to assemble.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0016] By using the positive terminal and negative housing as the positive and negative terminals in the circuit respectively, the number of terminals can be effectively reduced. At the same time, the negative terminal housing has a negative terminal solder joint and a hook piece that are integrally formed and bent at least one rear end, replacing the traditional clamping method. This greatly reduces the number of parts in the product, achieving the simplest structure, making production and assembly very easy, and reducing costs. In addition, the overall volume of the positive terminal and negative housing is larger to maximize the maximum current that can be passed, better meeting the needs of use.

[0034] Please refer to Figures 1 to 7 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which consists of an insulating body 10, a positive terminal 20, and a negative terminal shell 30.

[0035] The insulating body 10 includes a base 11 and a tongue plate 12 extending from the base 11. In this embodiment, the insulating body 10 is made of one-piece plastic material and is vertically arranged. The base 11 has a slot 101 on its side, and slots 101 are provided on both the left and right sides of the base 11. Additionally, the outer surface of the base 11 has recessed fastening grooves 102, two of which are symmetrically arranged on the left and right sides.

[0036] The positive terminal 20 is embedded and fixed on the insulating body 10. The positive terminal 20 has a first positive contact portion 21, a second positive contact portion 22, and a positive solder foot portion 23. The first positive contact portion 21 and the second positive contact portion 22 are respectively exposed on the two surfaces of the tongue plate 12, and the positive solder foot portion 23 extends out of the base 11. Specifically, the positive terminal 20 is formed by stamping and reverse bending of a metal plate. It includes two main body portions 24, which are stacked together. The first positive contact portion 21 and the second positive contact portion 22 extend from the front side of the two main body portions 24, respectively. The rear ends of the two main body portions 24 are integrally formed, bent and connected to form the positive solder foot portion 23 to meet the requirements of large current passage, allowing for a larger current to pass through. Furthermore, the first positive electrode contact 21 and the second positive electrode contact 22 are both symmetrically arranged. The two first positive electrode contacts 21 extend from the front sides of one main body 24, and the two second positive electrode contacts 22 extend from the front sides of the other main body 24, to better meet the requirements of reversible insertion. In addition, wings 25 extend from both sides of the two main body 24. Each wing 25 is located behind the first positive electrode contact 21 and the second positive electrode contact 22, and each wing 25 is embedded in the base 11, so that the positive terminal 20 is more firmly connected to the insulating body 10 and can better transmit large current. In addition, the positive electrode solder foot 23 extends vertically. The positive electrode solder foot 23 is located at the center of the base 11 and extends downward from the bottom surface of the base 11, so as to perform vertical insertion soldering with the external circuit board, making the connection structure more stable and reliable.

[0037] The negative electrode shell 30 covers the insulating body 10. At least one rear end of the negative electrode shell 30 is integrally formed and bent to extend a negative electrode solder foot 31 and a hook 32. The negative electrode solder foot 31 protrudes from the base 11, and the front end of the hook 32 abuts against the side of the tongue plate 12. In this embodiment, the negative electrode shell 30 is formed from a metal sheet by stamping, and the rear end of the hook 32 is embedded in the slot 101. Furthermore, both the left and right rear ends of the negative electrode shell 30 are integrally formed and bent to extend a negative electrode solder foot 31 and a hook 32. Both negative electrode solder feet 31 protrude from the base 11, and the front ends of the two hooks 32 abut against the left and right sides of the tongue plate 12, respectively. Moreover, the rear ends of the two hooks 32 are respectively embedded in the two slots 101, resulting in a simple and compact structure, while also making the plug-in connection structure more stable. Both negative electrode solder feet 31 extend horizontally and expose the bottom surfaces of the left and right ends of the base 11 respectively, so as to be surface-mounted with the external circuit board. In addition, the rear edge of the negative electrode shell 30 is bent and extended to form a fastener 33, which engages with the fastener groove 102 for fastening. There are two fasteners 33 arranged symmetrically on the left and right, and the two fasteners 33 engage with the two fastener grooves 102 respectively for fastening.

[0038] The assembly process of this embodiment is described in detail below:

[0039] During assembly, firstly, a positive terminal 20 and a negative terminal shell 30 are formed by stamping. Then, the positive terminal 20 is placed into an injection mold to form an insulating body 10, so that the positive terminal 20 is embedded and fixed on the insulating body 10. Then, the negative terminal shell 30 is fitted and fixed on the insulating body 10 from top to bottom.

[0040] During installation, place the product vertically on the circuit board so that the two negative electrode solder feet 31 are in contact with the solder pads on the circuit board for welding and conduction, and at the same time, insert the positive electrode solder foot 23 into the solder hole on the circuit board for welding and conduction.

[0041] When in use, insert the Type-C plug into this product until it is fully inserted. The outer shell of the Type-C plug contacts the negative outer shell 30, and at the same time, the grounding hook inside the Type-C plug engages with the locking hook 32, thereby achieving negative conduction. The first positive contact 21 or the second positive contact 22 contacts the corresponding power terminal inside the Type-C plug to achieve positive conduction.

[0042] The key design feature of this invention is that by using the positive terminal and the negative housing as the positive and negative terminals in the circuit respectively, the number of terminals can be effectively reduced. At the same time, at least one rear end of the negative housing is integrally formed and bent to extend the negative terminal solder foot and the hook, replacing the traditional clamping method. This greatly reduces the number of components in the product, achieving the simplest structure, making production and assembly very easy, and reducing costs. In addition, the overall volume of the positive terminal and the negative housing is larger to maximize the maximum current that can be passed, better meeting the needs of use.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
