[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1: Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a pin positioning buckle structure for an EMC bracket, including a pin body 100 and a docking member 200. There are two docking members 200, which are symmetrically arranged along the pin body 100. The docking members 200 are located on the outside of the pin body 100 and are used to dock with the PCB board. The docking member 200 includes a docking post 210 and a set of locking blocks 220 installed inside it. One side of the locking block 220 extends to the outside of the docking post 210, and the side of the locking block 220 away from the axis of the docking post 210 is inclined.

[0026] When positioning and docking the pin body 100 with the PCB board, the docking post 210 can be inserted into the corresponding positioning hole in the PCB board. At this time, the locking block 220 is deformed by the contact. Then, when the docking post 210 passes through the positioning hole, the locking block 220 is reset and contacts the back of the PCB board to complete the mechanical interlock. It should be noted that during actual positioning, users can choose to add a docking part 200 to the corresponding pin body 100 according to the EMC bracket specifications and positioning requirements to meet the positioning requirements.

[0027] Example 2: Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] Specifically, the docking component 200 also includes a damping ring 230, which is fixedly sleeved on the outside of the docking post 210, and a set of deformation joints distributed in a ring are provided on one side of the damping ring 230.

[0029] When the docking post 210 docks with the PCB positioning hole, the damping ring 230 will follow and enter. Then, the side of the damping ring 230 abuts against the inside of the positioning hole, changing from a ring shape to an umbrella shape, and is squeezed between the positioning hole and the docking post 210. It is inside the positioning hole to provide damping and reduce the occurrence of the resetting movement of the docking post 210. By using expansion joints, the expansion joints can be compressed and closed when the damping ring 230 deforms, ensuring the umbrella-shaped transformation effect of the damping ring 230 and reducing the occurrence of irregular deformation.

[0030] Specifically, an abutment ring 211 is fixedly sleeved on the outer side of the docking post 210, and the abutment ring 211 is located above the damping ring 230.

[0031] By utilizing the contact ring 211, during the docking process, when the contact ring 211 comes into contact with the PCB board, it indicates that the movement is in place, reducing the occurrence of over-insertion of the docking post 210 and improving positioning efficiency.

[0032] Specifically, a cover 110 is mounted on the outside of the pin body 100. Two crossbars 111 are rotatably connected to the outside of the cover 110. One end of the crossbars 111 passes through and slides to the outside of the docking post 210.

[0033] The card cover 110 is used to connect with the pin body 100, and the crossbar 111 is used to support the docking post 210. The user can also adjust the position of the docking post 210 according to the opening position of the positioning hole on the PCB board.

[0034] Specifically, a set of grooves is provided on the outer side of the crossbar 111, and a rubber disc 112 is fixedly installed to the outer side of the cover 110 inside the grooves.

[0035] Users can adjust the orientation of the docking post 210 end according to the bracket pins for different welding requirements. Users can directly apply force to rotate the docking post 210 so that the groove follows the movement. After rotating 90 degrees, it can be docked with the corresponding rubber disc 112.

[0036] Specifically, the docking post 210 has two sliders inside that dock with the crossbar 111, and the sliders slide against the crossbar 111 by friction.

[0037] By utilizing frictional sliding, it is convenient to adjust the insertion point of the docking post 210, and the frictional force can also be used to ensure the stability of the docking post 210 and reduce the occurrence of accidental sliding.

[0038] Example 3: Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0039] Specifically, an elastic ring is installed on the outside of the contact ring 211 and sleeved onto the outside of the docking post 210. Both the elastic ring and the damping ring 230 are made of rubber.

[0040] With the use of an elastic ring, when the locking block 220 contacts and mates with the back of the PCB board, there is a slight gap between the contact ring 211 and the PCB board. The elastic ring compensates for this area to ensure the firmness of the mating area. The choice of rubber material enables the elastic ring and damping ring 230 to deform, meeting actual positioning requirements.

[0041] Specifically, the material of the card block 220 is plastic, and the upper side of the inclined surface of the card block 220 is chamfered.

[0042] Made of plastic, it reduces the impact of circuit current shunting after the PCB board is powered on. The chamfered design reduces excessive wear between the PCB board and the positioning holes during the connection process.

[0043] Specifically, the cover 110 can slide along the surface of the pin body 100, and an injection groove is provided on the inner side of the cover 110.

[0044] The user can slide the card cover 110 to the corresponding position on the pin body 100, and then pour epoxy resin glue into the injection tank to complete the pre-fixation; It should be noted that the snap-fit ​​structure used in this application is a separate type. The docking of the cover 110 and the pin body 100 is completed in advance before the EMC bracket is attached to the PCB board. Alternatively, according to actual usage requirements, the docking post 210 can be integrally formed on the pin body 100 and the corresponding end orientation can be formed. The specific usage method can be selected according to actual needs.

[0045] Specifically, the docking post 210 has a set of storage slots for accommodating the card block 220 inside, and both the card block 220 and the storage slots are arranged in a ring around the axis of the docking post 210.

[0046] The storage slot provides storage space when the card block 220 enters the positioning hole in the PCB board.

[0047] In use, select the corresponding number of card covers 110 and install them onto the corresponding pin bodies 100. Then, depending on the soldering status of the pin bodies 100, rotate the end of the docking post 210 to the appropriate direction. Next, attach the EMC bracket to the PCB board, so that the pin bodies 100 are in the corresponding positions. At the same time, insert the docking post 210 into the positioning hole at the corresponding position. During the docking process, until the contact ring 211 and the elastic ring are tightly attached to the PCB, the elastic ring is in a compressed deformation state. After the card block 220 is docked with the back of the PCB board, the elastic ring slightly resets, completing the docking operation. At this time, the PCB board and the pin bodies 100 form a whole, providing firm support for the EMC bracket and reducing the occurrence of warping caused by soldering tension, ensuring the soldering effect and efficiency. Subsequent soldering operations can then be performed.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
