PCB terminal blocks have emerged as a result, conveniently connecting external wires or other electrical components to PCBs.

[0003] Generally, one end of a PCB terminal block is soldered to the PCB board, and the other end is connected to the wire with a bolt. The PCB terminal block then cooperates with the bolt to achieve electrical connection between the PCB board and external devices.

[0005] Despite this technological advancement, during the production and packaging process of these PCB terminal blocks, each PCB terminal block tends to overlap, meaning one PCB terminal block tends to be placed within the assembly area of ​​another PCB terminal block. This makes packaging of the PCB terminal blocks difficult, and during packaging, the overlapping PCB terminal blocks need to be manually separated one by one before packaging, significantly impacting packaging efficiency.

[0006] Therefore, the above technical problems need to be solved. Utility Model Content

[0014] Furthermore, the protrusion includes a long strip;

[0015] The long strip is disposed in the assembly area and extends from an inner wall of one of the side panels toward an inner wall of the other side panel.

DETAILED DESCRIPTION

[0035] The following will be combined with the Figure 1 To the attached Figure 5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that if there are any directions involved in the embodiments of the present invention, they shall be based on the directions shown in the drawings, such as front and back. Figure 1 The specific Figure 1 The left side is the front, Figure 1 The right side is the back; if a particular posture changes, the directional indication also changes accordingly.

[0037] PCB terminal blocks are used in many electronic devices, including mobile phones, tablets, and laptops. For example, small PCB terminal blocks are often used to connect various sensors (such as light sensors and proximity sensors) on a mobile phone's motherboard to the motherboard, as well as to connect the battery to the motherboard, to facilitate signal transmission and power supply. These terminals must meet the requirements of miniaturization and high reliability to meet the trend of thinner and more portable consumer electronics. Consequently, the demand for PCB terminal blocks has increased significantly.

[0038] However, during the packaging process of existing PCB board terminals, the PCB board terminals are easily overlapped, which requires manual separation of the PCB board terminals during packaging, seriously affecting the efficiency of packaging.

[0039] In this regard, the inventors provide an anti-stuck PCB board terminal block, the purpose of which is to prevent different PCB board terminal blocks from being easily nested together, which makes them difficult to package.

[0040] Detailed as Figures 1 to 3 As shown, the present technical solution is an anti-stuck PCB board terminal, including a terminal body 1, the terminal body 1 includes a welding plate 11, the welding plate 11 has an assembly hole 111, the assembly hole is used for welding with external equipment, such as being connected with a bolt, and the bolt can be connected with the wire of the external equipment to realize the electrical connection between the PCB board and the external equipment.

[0041] Side panels 12 extend longitudinally on the opposite sides of the welding plate 11. The welding plate 11 and the side panels 12 on both sides enclose the anti-stuck PCB board terminal into a hexahedral structure, and three surfaces of the hexahedral structure are closed surfaces composed of the welding plate 11 and the side panels 12 on both sides, and the other three surfaces are open, two of which are located on the other opposite sides of the welding plate 11, and the other opening is located on the opposite side of the welding plate 11.

[0042] In this embodiment, the opening adjacent to the side plate 12 is defined as a first opening 131 , and the opening opposite to the welding plate 11 is defined as a second opening 18 .

[0043] The two side plates 12 and the welding plate 11 together form an assembly area 13 . An inner wall 121 of each side plate 12 in the assembly area 13 has a protrusion 14 in a direction toward the assembly area 13 .

[0044] It should be understood that because the PCB board terminals in the prior art have an assembly area 13 between each other, such PCB board terminals are prone to overlapping during packaging, that is, one PCB board terminal is easily placed in the assembly area 13 of another PCB board terminal, requiring manual separation of the two PCB board terminals before packaging. To address this issue, the present technical solution provides a protrusion 14 on the inner wall 121 of each side panel 12. The protrusion 14 protrudes from the surface of the inner wall 121 toward the inside of the assembly area 13 and is integrally connected to the side panel 12. With this design, when another PCB board terminal is placed in the assembly area 13 of the PCB board terminal, it will be blocked by the protrusion 14 outside the assembly area 13 and cannot continue to move into the assembly area 13. This prevents the two PCB board terminals from overlapping each other, effectively solving the problem of such PCB board terminals being difficult to package and affecting packaging efficiency.

[0045] In a preferred embodiment, the protrusion 14 includes a bump 141 with a circular, square or elliptical cross section.

[0046] In this embodiment, the protrusion 14 is integrally connected to the side panel 12. Preferably, the protrusion 14 is set to be circular, square or oval, which facilitates mold molding production.

[0047] In other usage scenarios, the protrusion 14 is not limited to the shapes listed above, and can also have various shapes according to actual needs, as long as it is convenient for production and can prevent one PCB board terminal from being placed in the assembly area of ​​another PCB board terminal.

[0048] In a preferred embodiment, at least two protrusions 141 are respectively arranged on both sides of the inner wall 121 of each side plate 12 in the plugging direction of the anti-stuck PCB board terminal.

[0049] It should be understood that this design can prevent different PCB board terminals from entering the assembly area 13 through the two first openings 131 and the second opening 18. This can effectively prevent the PCB board terminals from overlapping each other, thereby improving packaging efficiency.

[0050] In a preferred embodiment, the protrusion 14 is provided on the inner wall 121 of the side panel 12 near the edge of the side panel 12 .

[0051] It should be understood that such a design blocks different PCB board terminals outside the assembly area 13 so that different PCB board terminals cannot enter the interior of the assembly area 13 from the first opening 131 and the second opening 18, thereby effectively preventing different PCB board terminals from overlapping each other.

[0052] In an embodiment of the utility model, as Figure 4 As shown, the protrusion 14 includes a long strip 142 ; the long strip 142 is disposed in the assembly area 13 and extends from the inner wall 121 of one of the side panels 12 toward the inner wall 121 of the other side panel 12 .

[0053] In this embodiment, the long strip 142 can effectively prevent another PCB board terminal from entering the assembly area 13 of the PCB board terminal, thereby effectively avoiding the problem that two different PCB board terminals overlap with each other, which makes packaging difficult and affects packaging efficiency.

[0054] In an embodiment of the utility model, Figure 1 As shown, a positioning foot 15 extends from the outer side surface of each side plate 12. The positioning foot 15 is parallel to the side plate 12 and is used for positioning and connecting with the PCB board.

[0055] In this embodiment, the positioning pins 15 are provided on the outer side surfaces of the side panels 12 for soldering to the PCB, facilitating connection to a PCB requiring side soldering in some usage scenarios. In actual usage scenarios, there are multiple positioning pins 15. In this embodiment, two positioning pins 15 are provided on the outer side surfaces of each side panel 12 to achieve a better fixed connection between the PCB terminal block and the PCB.

[0056] In an embodiment of the utility model, as Figure 2 and Figure 5 As shown, each side plate 12 has a through hole 16 at the connection with the welding plate 11; a gasket 17 is provided in the assembly section 13; and locking protrusions 171 are provided on both sides of the gasket 17. The locking protrusions 171 engage with the through hole 16 to enable the gasket 17 to be assembled in the assembly section 13. The gasket 17 has a first screw hole 172, which communicates with the assembly hole 111.

[0057] In this embodiment, the gasket 17 is used to increase the pitch of the assembly hole 111. Since the assembly hole 111 is used to be electrically connected to the bolt, the assembly connection between the assembly hole 111 and the bolt is prone to loosening over time, causing the bolt to fall from the assembly hole 111.

[0058] Therefore, a gasket 17 is provided in the assembly section 13. The gasket 17 has a first screw hole 172 that communicates with the assembly hole 111. The first screw hole 172 is used to increase the original pitch of the assembly hole 111, that is, the connection between the bolt and the PCB board terminal is strengthened by increasing the pitch, thereby preventing the bolt from falling off from the assembly hole 111.

[0059] In one usage scenario, the lower surface 112 of the welding plate 111 is in contact with the upper surface 173 of the gasket 17. It should be understood that such a design can further increase the pitch of the bolt connection, making the connection between the bolt and the PCB board terminal more stable.

[0060] To sum up, a PCB board terminal block that prevents jamming in the present technical solution is provided with a protrusion 14 on the inner wall 121 of the side panel 12. The protrusion 14 can effectively prevent different PCB board terminals from being easily placed in each other's assembly intervals 13, and the problem of jamming and overlapping between different PCB board terminals occurs, which seriously affects the packaging efficiency of the PCB board terminals.

[0061] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
