Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector structures, specifically to a TYPE-C male connector. Background Technology
[0002] In the field of Type-C interface applications, male connectors are usually designed for the cable end, and are rarely used on the device end. This is mainly because the use of male connectors on the device end has the following significant structural defects:
[0003] 1. Traditional male connectors are limited by their height and pad layout, making them difficult to adapt to compact electronic devices;
[0004] Second, pins directly soldered to the PCB lack mechanical support, resulting in a high failure rate of solder joints under insertion and extraction stress, which seriously affects the reliability of the equipment.
[0005] Therefore, male connectors need to be improved to enable their application in equipment. Utility Model Content
[0006] To address the problems in the existing technology, this utility model provides a TYPE-C male connector that can completely solve the inherent defects of male connectors on the device side, such as easy damage and poor compatibility, and effectively improve the stability of TYPE-C male connectors when used on the device side.
[0007] This utility model of a TYPE-C male connector includes a base, a boss disposed on the base, a TYPE-C plug extending from one side of the boss, and a pin for soldering to a PCB board on the base. The pin is electrically connected to the pins of the TYPE-C connector. The pin is flush with the lower surface of the base and protrudes from one side of the base. The base is provided with a positioning structure for positioning the installation position of the TYPE-C male connector.
[0008] Furthermore, the positioning structure consists of several positioning posts disposed on the lower surface of the base.
[0009] Furthermore, the base is also provided with a fixing structure for fixing the TYPE-C male connector.
[0010] Furthermore, the fixing structure includes a fixing plate and a lug extending from the fixing plate. The fixing plate is disposed inside the base, and the lug protrudes from the base. The TYPE-C male connector is fixedly connected to the PCB board through the lug.
[0011] Furthermore, the lug is disposed on the side opposite to the PIN pin, the lug is flush with the lower surface of the base, and protrudes from the side of the base.
[0012] Furthermore, the orientation of the pins on the base is opposite to the direction in which the TYPE-C plug extends.
[0013] Furthermore, the TYPE-C plug has a mating gap on its outer periphery for insertion into the TYPE-C female socket.
[0014] Furthermore, the TYPE-C male connector is a 7-pin male connector, with seven pins, including two VBUS pins, two GND pins, one DP pin, one DM pin, and one OTG pin.
[0015] Furthermore, the base and boss are made of glass fiber reinforced PBT plastic and are injection molded using engineering plastic integrated injection molding technology.
[0016] Compared with the prior art, the beneficial effects of this utility model are: by wrapping the TYPE-C plug with a shell and a three-dimensional reinforced structure, its overall performance can be significantly improved, solving the defect that the existing TYPE-C plug cannot be used on the PCB board of the device.
[0017] By setting a separate base and leading the pins out from the base, and setting a fixing structure on the other side of the base, the TYPE-C male connector can be stably fixed on the PCB board through the fixing structure and the pins, so as to meet the mechanical plugging and unplugging requirements of industrial equipment.
[0018] By encasing the Type-C male connector core module in a glass fiber reinforced PBT plastic shell, a stress buffer layer is formed, further enhancing the tensile strength of the solder joints. Attached Figure Description

[0024] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.
[0025] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figures 1-4 As shown, this utility model aims to mount the TYPE-C male connector on the PCB board, thereby achieving a foolproof design for the application equipment and avoiding the safety hazards caused by plugging and unplugging existing interfaces onto the equipment. Since existing TYPE-C male connectors are directly soldered to the PCB board via pins, their stability is low, and plugging and unplugging can easily lead to solder joint failure or even detachment of the TYPE-C male connector. Therefore, this utility model strengthens the structure of the TYPE-C male connector through structural design, making it meet the requirements of industrial-grade mechanical plugging and unplugging. Specifically, the TYPE-C male connector in this example includes a base 1, a boss 2 disposed on the base 1, and a TYPE-C plug 3 extending from one side of the boss 2. The base 1 also has a pin 7 for soldering to the PCB board. The pin 7 is electrically connected to the pins of the TYPE-C connector. The pin 7 is flush with the lower surface 101 of the base 1 and protrudes from one side of the base 1. The base 1 has a positioning structure for positioning the installation position of the TYPE-C male connector.
[0028] By setting a boss, the TYPE-C plug 3 is raised by a certain distance, so that the outer periphery of the TYPE-C plug 3 and the base 1 form a mating gap 6 for insertion into the TYPE-C female socket, which facilitates insertion and removal.
[0029] As one embodiment of this utility model, the base installation position can be positioned first by the positioning structure, and then the TYPE-C male connector of this utility model can be fixed on the PCB board by high temperature resistant adhesive.
[0030] like Figure 2 and Figure 3 As shown, the positioning structure of this utility model consists of a plurality of positioning posts 5 disposed on the lower surface 101 of the base 1. Of course, the positioning structure in this example could also be positioning holes corresponding to the marked positions on the PCB board. It could also be a fixing hole structure that mates with fixing posts on the PCB board, or other structures.
[0031] like Figures 1-4 The example shown employs a welding fixing method, and the base 1 is also provided with a fixing structure for fixing the TYPE-C male connector. The fixing structure in this example includes a fixing plate 8 and a lug 4 extending from the fixing plate 8. The fixing plate 8 is disposed inside the base 1, and the lug 4 protrudes from the base 1. The TYPE-C male connector is fixedly connected to the PCB board through the lug 4.
[0032] Preferably, there are two lugs 4, evenly distributed on the side opposite to the pin 7. The lugs 4 are flush with the lower surface 101 of the base 1 and protrude from the side of the base 1. By soldering the lugs 4 and the pin 7 to the PCB board, the base can be stably fixed to the PCB board.
[0033] Preferably, in this example, the orientation of the pin 7 on the base 1 is opposite to the protruding direction of the TYPE-C plug 3. This facilitates the arrangement of wiring within the base while improving insertion and removal strength.
[0034] As an embodiment of this utility model, the TYPE-C male connector in this example is a 7-pin male connector, with seven pins: two VBUS pins, two GND pins, one DP pin, one DM pin, and one OTG pin. Of course, this example also applies to 4-pin TYPE-C male connectors. Since the connection circuit board and pin connections of 7-pin male connectors with TYPE-C interfaces are existing mature technologies, they will not be described in detail here.
[0035] like Figure 4As shown, the base 1 and boss 2 in this example are made of glass fiber reinforced PBT plastic. The glass fiber reinforced PBT plastic shell covers the Type-C male core module to form a stress buffer layer, which improves the tensile strength of the solder joint.
[0036] The core module of this example Type-C male connector includes a connecting circuit board 9, a Type-C plug 3 located at one end of the connecting circuit board 9, and a pin plate 10 located at the other end of the connecting circuit board 9. The connecting circuit board 9 is set at a 90-degree angle, and the Type-C plug 3 and the pin plate 10 are arranged vertically and parallel to each other on both sides of the connecting circuit board 9. Then, a fixing plate 8 is arranged, and then injection molding is performed using engineering plastic integrated injection molding technology. Finally, the connecting plate of the pin plate 10 is removed to form the final pin.
[0037] The innovative aspects of this utility model compared to existing technologies are:
[0038] 1. Three-dimensional reinforced structure: The core module of the Type-C male connector is covered with a glass fiber reinforced PBT plastic shell to form a stress buffer layer, which improves the tensile strength of the solder joint;
[0039] 2. Precise Function Retention: The 7-pin gold-plated connector is retained, supporting fast charging and data transfer;
[0040] 3. Industrial-grade reliability: After multiple mechanical insertion and removal tests, there were zero solder joint failures.
[0041] This utility model structure can completely solve the inherent defects of the male connector on the device side, such as easy damage and poor compatibility, and provide a highly reliable connection solution for high-level plug-in scenarios such as financial terminals.
[0042] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
