Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figures 1 to 4 As shown, the present invention provides a TYPE-C male connector structure, including a housing 1, a core 2, a pin 3, an EMI spring 4, and a hook 5. The core 2 has a slot 21, and the pin 3, EMI spring 4, and hook 5 are respectively inserted into the corresponding slots 21. The housing 1 covers the outside of the core 2 and has a notch 11 for clamping and soldering the PCB board. The two sides of the hook 5 are in contact with the housing 1. The pin 3 is connected to the PCB board, and the EMI spring 4 is connected to the grounding point of the PCB board. The two ends of the EMI spring 4 are in contact with the housing 1.

[0015] The core 2 has different slots 21 for different PIN pins 3, EMI springs 4, and hooks 5. After the housing 1 is connected to the outside of the core 2, the end of the EMI spring 4 and the side of the hook 5 contact the housing 1 to achieve grounding. One end of the housing 1 has a notch 11 for clamping and soldering the PCB board, increasing the load-bearing capacity during the load test. At the same time, the PIN pins 3 are connected to the corresponding pins on the PCB board, the EMI springs are connected to the grounding point on the PCB board, and the hooks 5 connect to the PCB board through contact with the housing 1.

[0016] The core 2 has spring slots 22 at its upper and lower ends. The upper and lower ends of the EMI spring 4 pass through the spring slots 22 and contact the housing 1. The core 2 has spring slots 22 at its upper and lower ends corresponding to the slots 21 of the EMI spring 4, so that the EMI spring 4 can pass through the core 2 and contact the housing 1 to achieve grounding.

[0017] The EMI spring 4 has multiple raised points 41, which make contact with the housing 1. Using multiple raised points to achieve contact with the housing 1 not only increases the friction between the EMI spring 4 and the inner wall of the housing 1, but also increases the number of contact points, reducing the contact error rate. This ensures a firm contact between the EMI spring 4 and the housing 1, thus achieving grounding.

[0018] The side of the core 2 has a hook slot 23, through which the two sides of the hook 5 pass and contact the housing 1. The core 2 also has hook slots 23 on the side corresponding to the slot 21 of the hook 5, serving as clearance positions so that the hook 5 can make interference contact with the housing 1, and is then soldered to the PCB board by the housing 1 for direct grounding. This structural design saves space and ensures the stability of the direct grounding wire in the housing 1.

[0019] The core 2 has a positioning hole 24, and the hook 5 has a pin 51, which is engaged with the positioning hole 24. After the hook 5 is inserted into the corresponding slot 21 of the core 2, the pin 51 is also aligned and inserted into the positioning hole 24 of the core 2, which serves to position the hook 5 and make it securely positioned.

[0020] The housing 1 has a stepped plane 12 that extends to cover the area where the PIN pin 3 and EMI spring 4 protrude from the core 2. After the PIN pin 3 and EMI spring 4 are inserted into the slot 21 of the core 2, some of them will protrude from the end of the core 2. After the stepped plane 12 of the housing 1 extends outward to cover the protruding area of ​​the PIN pin 3 and EMI spring 4, the stepped plane 12 of the housing 1 has a large area, which is beneficial for spot laser welding.

[0021] The housing 1, PIN pins 3, EMI springs 4, and hooks 5 are all made of conductive materials. The housing 1 can be made of iron to achieve conductive contact between the PIN pins 3 and the PCB board, conductive contact between the PIN pins 3 and hooks 5 and the housing 1, and conductive contact between the housing 1 and the PCB board.

[0022] The assembly process for this TYPE-C male connector is as follows: Insert the PIN pin 3, EMI spring 4, and hook 5 into the corresponding slots 21 on the core 2. The hook 5 is positioned and fixed by the pin 51 and the positioning hole 24 of the core 2 after being inserted into the slot 21. Fit the housing 1 onto the outside of the core 2, and make the flat boss of the housing 1 cover the area where the PIN pin 3 and EMI spring 4 protrude from the core 2. The EMI spring protrudes from the spring slot 22 of the core 2 and contacts the upper and lower inner walls of the housing 1. The side of the hook 5 protrudes from the hook slot 23 of the core 2 and contacts the side inner wall of the housing 1. Clamp the PCB board at the notch 11 of the housing 1 and solder it. At the same time, the corresponding pins of the PCB board are connected and soldered to the PIN pin 3, and the corresponding grounding point of the PCB board is connected and soldered to the EMI spring 4, completing the overall assembly.

[0023] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
