Description

Technical Field

[0001] This application belongs to the field of connector technology, and in particular relates to a PCB socket suitable for printed circuit boards. Background Technology

[0002] Soldering is a common method for connecting electronic components to a PCB board. However, the high temperatures generated during soldering can adversely affect the components, leading to performance degradation. Furthermore, the fixed connection after soldering makes disassembly difficult, potentially reducing product lifespan. A contrasting solution is to solder the PCB socket to the PCB board first, then connect the socket and electronic components. This not only avoids the effects of high temperatures during soldering but also facilitates easy component replacement, extending product lifespan.

[0003] However, this method also has the following shortcomings:

[0004] 1. The PCB socket needs to be soldered onto the PCB board, which results in insufficient modularity and makes it difficult to replace the socket when it is damaged.

[0005] 2. The PCB socket needs to be soldered onto the PCB board, which is inconvenient and inefficient during soldering.

[0006] 3. Hazardous substances generated during welding may pollute the environment and endanger the health of employees. Utility Model Content

[0012] Preferably, the connection between the plate wing and the receiving body has a bend to provide elastic force when the plate wing is crimped between the plate wing and the printed circuit board.

[0013] Preferably, the contact piece has a roughly triangular structure.

[0014] Preferably, the sidewall of the receiving body has a cut-out frame portion, each cut-out frame portion corresponds to a corresponding contact piece, and each contact piece is formed by cutting off the corresponding cut-out frame portion from the receiving body to leave the corresponding contact piece.

[0015] Preferably, a horizontal arm is provided in the middle of the cut-out frame portion, and the first end of each of the contact pieces is connected to the horizontal arm.

[0016] Preferably, each of the contact pieces is further provided with a corresponding inverted clip, which is connected to both sides of the cross arm respectively with the corresponding contact piece.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] like Figures 1 to 4 As shown in the preferred embodiment of this application, a PCB socket 10 is provided, which is an integral structure formed by stamping a metal sheet, for connecting a connector 21 (see reference). Figure 4 and combined Figure 1 The PCB (printed circuit board 30) includes a receiving body 11 defining a docking plug 21, a plurality of contact pads 12, and plate wings 13. In this embodiment, the contact pads 12 are three identical sheet-like structures, roughly triangular in shape; the plate wings 13 are a pair and symmetrically arranged on both sides of the receiving body 11; the PCB socket 10 is electrically connected to the printed circuit board 30 by crimping through its plate wings 13.

[0027] refer to Figure 1 , Figure 2 As shown, in this embodiment, the receiving body 11 is a cylindrical component with a circle, including a first end 111 with an opening, a second end 112, and a side wall 113 located between the first end 111 and the second end 112. The side wall 113 is arranged around the central longitudinal axis and is formed by rolling a slit 114 extending from the first end 111 to the second end 112 of the receiving body 11 through a rolling process.

[0028] In this embodiment, the first end 121 of each contact piece 12 is connected to the receiving body 11, and the second end 122 of each contact piece 12 is bent radially inward relative to the first end 121 of the contact piece 12 toward the central longitudinal axis. With this arrangement, each contact piece 12 can abut against the docking plug 21 and form a retaining force, thereby reliably engaging with the docking plug 21.

[0029] In this embodiment, the plate wing 13 extends outward from the first end 111 of the receiving body 11, has an arched bend 133 at the connection with the receiving body 11, and has an outwardly extending flat surface 131 for connecting to the printed circuit board 30. Through the elastic force provided by the bend 133, when the plate wing 13 and the printed circuit board 30 are pressed together, a stable and reliable connection that is not easy to separate is formed.

[0030] Furthermore, each of the plate wings 13 has two protrusions 132 on its flat surface 131 to form contact points 134 for pressing and connecting the plate wings 13 and the printed circuit board 30, further improving the reliability of the contact between the plate wings 13 and the PCB of the PCB socket 10. Of course, in other embodiments, more protrusions 132 can be provided as needed to ensure a more reliable contact effect.

[0031] Furthermore, the sidewall 113 of the receiving body 11 has a cut-out frame portion 115, each of the cut-out frame portions 115 corresponding to a corresponding contact piece 12, and each contact piece 12 is formed by cutting off the corresponding cut-out frame portion 115 from the receiving body 11, leaving the corresponding contact piece 12. This arrangement simplifies the manufacturing realization of the structure.

[0032] Furthermore, a horizontal arm 116 is provided in the middle of the cut-out frame portion 115, and the first end 121 of each of the contact pieces 12 is connected to the horizontal arm 116, making the overall structure of the side wall 113 more elastic and with sufficient strength.

[0033] To further enhance the reliability between the PCB socket 10 and the PCB, multiple inverted tabs 14 can be provided on the side wall 113, corresponding to the number of each contact tab 12, and arranged symmetrically on both sides of the cross arm 116, which can achieve better space utilization and realize reliable connection.

[0034] In this structure, each inverted tab 14 extends outward at an angle to the central longitudinal axis. This allows the receiving body 11 to be positioned by inverting each tab 14 onto the printed circuit board 30, thereby improving the reliability of the PCB mounting and preventing displacement.

[0035] In summary, unlike traditional soldering methods, the PCB socket of this application is electrically connected to the PCB by a crimping method, which facilitates installation and disassembly, promotes modularity, simplifies the structure, and provides good contact reliability.

[0036] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
