Description

Technical Field

[0001] The present application relates to the field of PCB packaging, and in particular to a PCB packaging and connector for solving the floating height problem of connector terminals. Background Art

[0002] Conventional PCBs require connector terminals to connect to cables for data transmission. During mass production, the PCBs, which utilize numerous connector terminals, must be connected to the connector terminals through a soldering iron furnace. During this process, many terminals can become raised due to vibrations in the soldering iron furnace chain, necessitating manual inspection and repair. This reduces the PCB's pass rate and increases costs. Utility Model Content

[0022] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. Specific embodiments

[0023] In the description of this application, it is necessary to understand that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship described in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or the number of technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0025] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0026] To provide a clearer and more accurate understanding of the contents of this application, the following detailed description will be made with reference to the accompanying drawings. The accompanying drawings illustrate examples of embodiments of this application, with like reference numerals representing like elements. It should be understood that the scales shown in the accompanying drawings are not those of the actual implementation of this application. These scales are for illustrative purposes only and are not drawn to scale.

[0027] like Figure 1 As shown, the PCB package includes a PCB board 1 and connectors 2 connected to the PCB board 1. The PCB board 1 is connected to a large number of connectors 2, and data transmission is performed by connecting the cables via the connector terminals 20 in the connectors 2. In this embodiment, several connectors 2 are soldered to the PCB board 1 using a soldering furnace. Other soldering methods can also be used to solder the multiple connectors 2 to the PCB board, and are not limited here.

[0028] like Figure 2 and Figure 3As shown, connector 2 includes first connector terminals 21 and second connector terminals 22 arranged side by side with first connector terminals 21. First connector terminals 21 are arranged at both ends of connector 2, and second connector terminals 22 are arranged between first connector terminals 21. Specifically, first connector terminals 21 are arranged at the edges of connector 2 at both ends, forming a symmetrical structure. This allows connector terminals 20 to be more tightly connected to the PCB when passing through the solder pot. Second connector terminals 22 are spaced apart between the first connector terminals 21 at the edges.

[0029] In this embodiment, the connector 2 is provided with a row of connector terminals at intervals, the first connector terminals 21 are provided at both ends of the connector 2 , and the second connector terminals 22 are provided between the two first connector terminals 21 at intervals.

[0030] In another embodiment, connector 2 is provided with two rows of connector terminals 20 spaced apart and parallel to each other. First connector terminals 21 are provided in each row near the left and right edges of connector 2, i.e., at the four corners of connector 2. Second connector terminals 22 are provided between two first connector terminals 21 in each row. The arrangement and number of first connector terminals 21 and second connector terminals 22 described above are merely examples and are not intended to be limiting.

[0031] like Figure 4 As shown, both the first connector terminal 21 and the second connector terminal 22 include a through hole and a rim extending around the through hole. The first rim 212 of the first connector terminal 21 extends toward the first through hole 211, making the diameter of the first through hole 211 smaller than the diameter of the second connector terminal 22. Specifically, the first connector terminal 21 includes a first through hole 211 and a first rim 212 extending around the first through hole 211. The first rim 212 expands inward, shrinking the first through hole 201. The second connector terminal 22 includes a second through hole 221 and a second rim 222 extending around the second through hole 221. The diameter of the first through hole 211 is smaller than the diameter of the second through hole 221. The connector terminals and through holes can be circular, square, or other shapes, without limitation. This design of shrinking the rim allows for a tighter connection between the terminals and the PCB, preventing them from floating during soldering due to vibrations from the soldering chain. This improves the pass rate of the PCB and reduces costs.

[0032] In this embodiment, the first through holes 211 of the two first connector terminals 21 at both ends of connector 2 are narrowed inward, reducing the diameter of the first through holes 211. The diameter of the second through holes 221 of the second connector terminals 22 remains unchanged. In another embodiment, the first through holes 211 of the four first connector terminals 21 at the four corners of connector 2 are narrowed inward, reducing the diameter of the first through holes 211. The diameter of the second through holes 221 of the second connector terminals 22 remains unchanged. The first connector terminals 21 and the second connector terminals 22 have the same size.

[0033] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.

[0034] The above examples are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
