Description

Technical Field

[0001] This utility model relates to the field of brush terminal technology, and in particular to a puncture-type multi-group direct-connection brush terminal. Background Technology

[0002] In existing electronic device connection technologies, data cables serve as a crucial medium for transmitting data and power. The rationality of their structure and the stability of their performance directly affect the overall operation of the device. Traditional data cable structures often suffer from problems such as complex connections, easy loosening, and low transmission efficiency. This is especially true in scenarios requiring multiple connections or high-speed data transmission. For example, in applications that require simultaneous connection of multiple devices or large data transfers, traditional data cables may experience signal attenuation or transmission interruption due to excessive connection points and wire connections, severely impacting the user experience. Therefore, there is an urgent need for a brush terminal structure that can ensure the stability of multiple direct connections, provide high-efficiency transmission performance, and is simple in structure and low in production cost. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned technologies, such as the easy occurrence of poor contact at the connection contacts of the brush terminals, high production costs, and low production efficiency, this utility model provides a puncture-type multi-group direct-connection brush terminal.

[0004] To achieve the above objectives, this utility model provides a puncture-type multi-group direct-connection brush terminal, including a terminal piece. The terminal piece includes a plastic base plate and a metal sheet. The metal sheet is injection molded into the plastic base plate, and at least one stamped opening is formed on the plastic base plate. At least one conductive line is formed on the metal sheet, and at least one connecting contact point is provided on the conductive line, which corresponds to the position of the stamped opening and is formed by stamping. The connecting contact point protrudes from the stamped opening, and each of the conductive lines is also connected to an input pin.

[0007] As an improvement of this utility model, the number of connecting contact points on any of the conductive lines is the same as the number of connecting contact points on the other conductive lines.

[0008] As an improvement of this utility model, the connecting contact point is a curved structure protruding from the surface of the metal sheet.

[0009] As an improvement of this utility model, there is a gap between adjacent conductive lines.

[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model provides a puncture-type multi-group direct-connection brush terminal, including a terminal piece, which includes a plastic base plate and a metal piece. The metal piece is injection molded into the plastic base plate, and at least one stamped opening is formed on the plastic base plate. At least one conductive line is formed on the metal piece, and at least one connecting contact point is provided on the conductive line corresponding to the position of the stamped opening and formed by stamping.

[0013] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0014] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0015] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0016] Please see Figures 1-5 This utility model discloses a puncture-type multi-group direct-connection brush terminal, comprising a terminal piece, which includes a plastic base plate 1 and a metal sheet 2. The metal sheet 2 is injection molded into the plastic base plate 1, and the plastic base plate 1 has at least one stamped opening 6. At least one conductive line 3 is formed on the metal sheet 2, and the conductive line 3 has at least one connecting contact point 4 corresponding to the position of the stamped opening 6 and formed by stamping. The connecting contact point 4 protrudes from the stamped opening 6, and each conductive line 3 is also connected to an input pin 5. The brush terminal of this utility model is composed of an integral metal sheet 2 and a plastic base plate 1. The plastic base plate 1 is made by plastic molding, and the metal sheet 2 is fixed and insulated by injection molding. Multiple conductive lines 3 are formed on the metal sheet 2. On each conductive line 3, there is a connecting contact point 4 formed by stamping through the stamped opening on the plastic base plate 1. The multiple conductive lines are combined to form the circuit required for charging and other functions. Since the metal sheet 2 itself has conductive properties, the metal sheet 2... The above improvements are sufficient to achieve the same function as traditional brush terminals. Therefore, by setting the connecting contact point 4, the circuit can be made conductive. Compared with traditional brush terminals, which connect each connecting contact point 4 and input pin 5 through wires, which is more expensive, the integrated design of this utility model has a simple and compact structure. While achieving the same function, the connecting contact points 4 formed by stamping on the metal sheet 2 do not require any wire connection. This not only saves a lot of material costs but also greatly improves production efficiency. Furthermore, it improves conductivity within the effective space, meets the high current conductivity required by the product, and greatly improves the production process efficiency. The multi-contact metal sheet connection saves the process costs of circuit boards, assembly, and surface mounting compared to conventional production processes. In use, the input pin 5 of the metal sheet 2 can be processed into a plug that is compatible with any type of interface in the prior art, so that it can be directly inserted into the corresponding interface, or it can be connected by soldering wires on the input pin 2.

[0017] In this embodiment, the connecting contact 4 includes a positive power contact, a negative power contact, a positive data transmission contact, a negative data transmission contact, and a PD fast charging contact; the input pin 5 includes a positive power pin, a negative power pin, a positive data transmission pin, a negative data transmission pin, and a PD fast charging pin. This invention includes, but is not limited to, the above types of contacts and pins. The number and type of contacts and pins can be set according to the application scenario. In practical applications, by setting the same type of contacts on the conductive line 3, the working efficiency of the terminals can be greatly improved, enabling the brush terminals to simultaneously meet multiple needs for power transmission, data transmission, and fast charging, greatly improving ease of use and device compatibility. For example, in the charging scenario of smart devices, the cooperation between the PD fast charging contact and the PD fast charging pin can achieve efficient fast charging, meeting the user's need for rapid power replenishment.

[0018] In this embodiment, all connecting contacts 4 on the same conductive line 3 are of the same type, and the type of input pin 5 on the same conductive line 3 is the same as that of connecting contacts 4. By limiting the connecting contacts 4 and input pin 5 of the same type on the same conductive line 3, the circuit connection of the brush terminals is clearer and more orderly, avoiding signal interference or transmission errors that may be caused by mixing different types of contacts and pins. This further improves the performance stability and data transmission accuracy of the brush terminals, and also facilitates operation and inspection by production personnel, thereby improving production efficiency and product quality. For example, during the production process, workers can quickly identify and install contacts and pins of the same type, reducing production problems caused by misinstallation or omission.

[0019] Furthermore, the number of connection points on any conductive line is the same as the number of connection points on other conductive lines. By unifying the number of connection points on each conductive line, the brush terminals are made more regular and symmetrical in structure. This not only facilitates standardized production of the product, but also provides a consistent number of interfaces when connecting multiple devices, meeting diverse connection needs. In scenarios where multiple devices of the same type need to be connected simultaneously, the same number of connection points on each conductive line can ensure that each device can obtain a stable and consistent connection, avoiding connection problems caused by inconsistent contact numbers, and improving the overall reliability and stability of the connection.

[0020] In this embodiment, the connecting contact point 4 is a curved structure protruding from the surface of the metal sheet 2. This curved structure can generate elastic deformation when under pressure, ensuring that the connecting contact point 4 is in close contact with the mating terminal and improving conductivity stability. At the same time, a wear-resistant coating can be added to the top of the curved structure to increase wear life. The metal sheet 2 is fixed to the plastic base plate 1 by insert injection molding process. Each conductive line 3 and the input pin 5 are connected by laser welding to achieve high-precision electrical connection, ensuring the reliability of signal transmission.

[0021] In this embodiment, there is an isolation gap between adjacent conductive lines. By setting the isolation gap, the signal transmission of different conductive lines does not interfere with each other, effectively avoiding electromagnetic interference problems that may be caused by conductive lines. This ensures that each conductive line can transmit signals independently and stably, improving the reliability and stability of the brush terminal in multiple direct-connection applications. Especially in scenarios where multiple different types of signals need to be transmitted simultaneously, the isolation gap can ensure that each signal can be transmitted accurately and without interference to the corresponding device. For example, when transmitting power signals and data signals simultaneously, the isolation gap can prevent the power signal from interfering with the data signal, ensuring the accuracy and integrity of data transmission.

[0022] The advantages of this utility model are: 1. The brush terminal of this utility model has the characteristics of compact and simple structure. By setting conductive lines on the metal sheet and setting contact points generated by stamping, it is not necessary to connect each contact point with wires, which reduces the material cost of wires and can greatly improve production efficiency.

[0023] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
