Description

Technical Field

[0001] This utility model relates to the field of TYPE-C technology, specifically to an integrated terminal TYPE-C male connector with an EMC spring. Background Technology

[0002] The TYPE-C male connector features a double-sided mating design, supporting high-speed data transmission and high-power power transmission. Due to its miniaturization and multi-functionality, it has become a key interface component in consumer electronics such as smartphones and laptops, as well as in the field of new energy vehicles.

[0003] Type-C male connectors support ultra-high-speed transmission, but high-frequency signals are susceptible to external interference or their own inherent characteristics. Furthermore, without effective grounding, the metal casing of the Type-C interface can act as an antenna, radiating electromagnetic energy and interfering with nearby devices. The high current of the Type-C interface can also cause voltage fluctuations or static electricity buildup. Therefore, a separate EMC grounding spring (EMCI GND SPRING) is typically installed in Type-C connectors to conduct interference current to ground, achieving grounding shielding, preventing signal reflection and crosstalk, providing a low-impedance discharge path, and avoiding the risk of electrical sparks or arcs. However, designing and assembling the EMC grounding spring separately in the interface increases the manufacturing cost of the connector. Additionally, given the technical requirements of Type-C interfaces, the industry currently generally develops multiple plastic assemblies, resulting in complex structures and high development costs. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated terminal TYPE-C male connector with an EMC spring, so as to solve the problems mentioned in the background art of separately designing and assembling the EMC grounding spring in the plug, and reducing the manufacturing cost of the plug by injection molding the plastic body in one step.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated terminal TYPE-C male connector with EMC spring: comprising a plastic body, an integrated terminal, and a latch.

The purpose of this design is to utilize the space of the angle difference between the outer plastic and inner plastic to form a partition rubber position on the outer plastic in one step. The function of this partition rubber position is to prevent the terminal head from overlapping with the shell when the male and female are plugged in, which would cause short circuit and electrical failure.

The GND grounding pins on both sides of the integrated terminal are designed with connecting bodies on the terminal head. The connecting bodies are designed with 3 EMC springs for grounding shielding. The connecting bodies are also designed with protrusions, which contact the outer shell to provide grounding shielding.

[0029] 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.

[0030] Please see Figure 1-7 One embodiment provided by this utility model:

[0031] An integrated TYPE-C male connector with an EMC spring, comprising:

[0032] Outer shell 1: Outer shell 1 is a metal shell, formed by stamping, with an internal cavity. The above structure allows the plastic body to be assembled and accommodated inside the outer shell 1;

[0033] Plastic body 2: includes outer plastic 21 and inner plastic 22. The outer plastic 21 and inner plastic 22 are formed into separate but interconnected inclined structures with the integrated terminal 3 through a one-time injection molding process. The design utilizes the space dimensions of the inclined structure to directly design and form partition rubber positions 29 on the outer plastic 21. These partition rubber positions 29 correspond to multiple sets of positions with the tip shape of the terminal PIN. The partition rubber positions 29 can ensure that the force of the integrated terminal 3 is controlled when the connector is mated. The arm descends to prevent the head of the integrated terminal 3 from contacting the outer shell 1 or overlapping between adjacent pins, which could cause short circuits and electrical malfunctions. The outer plastic 21 and inner plastic 22 are respectively designed with interlocking outer plastic clips 23 and inner plastic clips 24 on their left and right sides. The outer plastic 21 and inner plastic 22 are pressed downwards and fastened together by the outer plastic clips 23 and inner plastic clips 24 to form a flat plastic body 2. The front end of the plastic body 2 has a first set of symmetrical fixing structures: one side has an outer plastic square pillar 25, and the other side has an outer plastic square hole 26. The rear end of the plastic body 2 has a second set of symmetrical fixing structures: one side has an outer plastic cylinder 27, and the other side has an outer plastic round hole 28. In this way, two plastic bodies are fastened together using two sets of symmetrical fixing structures to form a TYPE-C male connector body, making assembly very easy.

[0034] Integrated Terminal 3: Includes terminal functional PIN pins 31. Connecting bodies 32 are designed on the GND grounding PIN pins on both sides of the terminal PIN pins to connect the GND grounding PIN pins of the terminal group together. Three EMC grounding springs and bumps 34 are designed on the terminal connecting bodies 32. The bumps 34 are designed to contact the inner wall of the metal shell after the product is assembled to conduct ground. This forms the shell 1, bumps 34, and contact EMC springs 33. The three are connected to the terminal GND grounding PINs by the connecting bodies 32 to achieve a better grounding shielding effect. At the same time, the EMC grounding springs are directly developed and designed and stamped into the terminal structure in one piece. This structure can save the current industry's separate development, design and assembly process of EMC springs, thereby reducing manufacturing costs.

[0035] Hook 4: Hook 4 is designed with symmetrical fixing holes that correspond to the cylinder of the plastic body 2, allowing for assembly in both directions without the need for error prevention.

[0036] Furthermore, the integrated terminal 3 is designed with 12 pins, which are fixed together with the plastic body 2 by INSERT-MOLDING injection molding to realize the transmission function of the TYPE-C interface.

[0037] Furthermore, the integrated terminal 3 structure features a connecting body 32 on both sides of the GND grounding pin. The connecting body 32 is equipped with three EMC grounding springs 33 and protrusions 34. The protrusions 34 can contact the inner wall of the metal casing 1 to conduct ground. This forms a whole by connecting the casing 1, protrusions 34, and contact EMC springs 33 through the connecting body 32 and the terminal GND grounding pin, achieving a better grounding shielding effect. At the same time, the EMC grounding springs are directly designed and stamped into the terminal structure in one piece. This structure can eliminate the current industry practice of separately developing and assembling EMC springs, thereby reducing manufacturing costs.

[0038] Furthermore, before the plastic body 2 is fastened, the outer plastic 21 and inner plastic 22 are formed into separate and connected inclined structures by the INSERT-MOLDING process with the integrated terminal 3. The design utilizes the space size of the inclined structure to directly design and form the partition glue position 29 on the outer plastic 21. The partition glue position 29 corresponds to the terminal PIN and has multiple sets of spaces with the shape of the terminal PIN tip. The partition glue position 29 can ensure that when the male and female connectors are connected, the lever arm of the integrated terminal 3 moves downward, preventing the head of the integrated terminal 3 from contacting the outer shell 1 or the adjacent PINs from overlapping, which would cause short circuits and electrical failures.

[0039] Furthermore, the outer plastic 21 and the inner plastic 22 are fastened together into a flat part by corresponding outer plastic fasteners 23 and inner plastic fasteners 24.

[0040] Working principle: The integrated terminal 3 is designed with 12 PIN contact pins 31, which can be plugged into each other to achieve TYPE-C functionality. The integrated terminal 3 has a connecting body 32 on the left and right sides for the GND grounding pin. The connecting body 32 is designed with 3 grounding EMC springs 33 and bumps 34. The bumps 34 can contact the inner wall of the metal shell 1 to conduct ground. In this way, the shell 1, the bumps 34, and the contact EMC springs 33 are connected to the terminal GND grounding pin through the connecting body 32 to form a whole, achieving a better grounding shielding effect. The contact function pins 31 of the integrated terminal 3 are designed at a certain angle and are formed into separate but connected outer plastic 21 and inner plastic 22 through the INSERT-MOLDING one-time injection molding process. The design utilizes the inclined angle structure. The space dimensions are directly designed and molded into the partition rubber position 29 on the outer plastic 21. The partition rubber position 29 corresponds to the terminal PIN and is designed with multiple sets of positions with the shape of the terminal PIN tip. The partition rubber position 29 can ensure that when the male and female connectors are connected, the lever arm of the integrated terminal 3 moves downward, preventing the head of the integrated terminal 3 from contacting the outer shell 1 or the adjacent PINs from overlapping, which would cause short circuits and electrical failures. The outer plastic 21 and the inner plastic 22 are designed with interlocking outer plastic fasteners 23 and inner plastic fasteners 24 on the left and right sides respectively. The outer plastic 21 and the inner plastic 22 are pressed downward and connected by the outer plastic fasteners 23 and inner plastic fasteners 24 to form a flat plastic body 2. The front end of the plastic body 2 is designed with the first set of symmetrical fixed structures: one side is an outer plastic square post 25, and the other side is an outer plastic square hole 26. The upper and lower ends of the plastic body 2 are designed with a second set of symmetrical fixing structures: one side is an outer plastic cylinder 27, and the other side is an outer plastic hole 28; thus, the upper and lower 2PCS plastic bodies, with the hook 4 in the middle, are fastened together by the two sets of symmetrical fixing structures to form a TYPE-C male connector body. Then, the TYPE-C male connector body is fitted into the metal shell 1 to form a TYPE-C male connector product, realizing the TYPE-C contact transmission function.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
