Description

Technical Field

[0001] The utility model relates to the technical field of connection devices for PCB boards, in particular to a connector and a board-to-board connection device. Background Art

[0002] With the miniaturization and multifunctionality of electronic devices, connections between printed circuit boards (PCBs) are becoming increasingly important. In many applications, such as between a computer motherboard and expansion cards, or between components within communications equipment, electrical connections between two or more PCBs are required. These connections often require not only reliable electrical signal transmission but also, in some cases, a degree of mechanical flexibility to accommodate fine-tuning during assembly or relative displacement due to factors such as thermal expansion during use.

[0003] Traditional PCB-to-PCB connection methods include direct soldering, pin / female header combinations, and flexible cable connections. However, these methods all have limitations. For example, while direct soldering is simple and low-cost, it cannot be easily disassembled once completed. Pin / female headers, while allowing for repeated insertion and removal, lack the physical stability they provide for vertically arranged applications requiring a certain degree of floating support, easily leading to poor contact or even damage.

[0004] Traditional solutions become even more complex when two PCBs are perpendicular to each other and one of them requires floating. The typical approach involves soldering a specially designed connector to each PCB and then using these two connectors to establish an electrical connection. While this approach can meet the requirements to a certain extent, it increases overall system complexity and manufacturing costs due to the additional installation steps and the potential need for custom connectors with specially shaped shapes.

[0005] In order to solve the above problems, the present application proposes a connector and a board-to-board connection device. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a connector and a board-to-board connection device.

[0008] Furthermore, a plurality of needle slots for installing pins are arranged at intervals in the outer shell, one side of the needle slot has a notch for the elastic contact portion to extend out, and the bottom of the needle slot has a through hole for the welding end to extend out.

[0009] Furthermore, the connection positioning mechanism includes a positioning column, a positioning plate and a connection hook, the positioning column is inserted into the positioning hole connected to the PCB board 2, the positioning plate and the connection hook pass through the connection groove on the PCB board 2, and the connection hook can be hooked on the PCB board 2 after passing through the connection groove.

[0010] The present application also provides a board-to-board connection device, comprising:

[0011] A bracket, the bracket comprising a mounting back plate and a base, the base being provided with a mounting cavity;

[0012] The connector is installed in the installation cavity, an insertion gap for inserting a PCB board is left between the connector and the installation backplane, and the elastic contact portion is in contact with the PCB board.

[0013] Furthermore, elastic connecting feet are provided on both sides of the base, and the elastic connecting feet include a support rod connected to the base and a tilt rod connected to the support rod, and the top of the tilt rod is provided with clamping grooves for clamping the two ends of the PCB board.

[0014] Furthermore, corresponding fixing holes are provided on the PCB board 1 and the mounting back plate.

[0015] The beneficial effects of the utility model are:

[0016] 1. Cost saving: After adopting the connector of the technical solution of this application, only one connector is needed to connect two vertical PCB boards, saving costs.

[0017] 2. Simplified assembly: By designing the bracket to include a mounting backplate and base, with a dedicated mounting cavity in the base for accommodating the connector, the entire connection structure is made more compact. This design not only reduces the number of required components but also simplifies the assembly process between PCBs. The entire device only requires a single connector, reducing production costs.

[0018] 3. Improved electrical connection reliability: Pins with elastic contacts automatically adjust and maintain good contact with the PCB once the PCB is inserted into the gap. This ensures stable signal transmission even with slight vibration or displacement, thereby improving overall system reliability and service life.

[0019] 4. Support for vertical floating requirements: For applications requiring a certain amount of floating in one direction, this device provides the necessary mechanical flexibility through a rational structural layout (i.e., the insertion gap between the connector and the mounting backplane). PCB One can float up and down within the insertion gap to adapt to different working conditions, while also facilitating its removal and replacement. This helps alleviate stress concentration caused by factors such as temperature fluctuations and vibration, protecting electronic components from potential damage.

[0020] 5. Easy maintenance and upgrades: Thanks to its modular design, if a PCB needs to be replaced or upgraded in the future, simply remove the old board from the connector and insert the new one. This greatly enhances the product's maintainability and allows users to easily expand the system or improve performance.

[0021] 6. Strong adaptability: By adjusting the position and size of the connection positioning mechanism, the relative position between the two PCBs can be easily adjusted, making it suitable for connecting circuit boards of different specifications and models. In addition, the flexible and changeable pin configuration scheme also supports various types of interface standards, expanding the application range.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] The utility model provides a board-to-board connecting device.

[0032] In this embodiment, referring to Figure 1-5 , the connector includes:

[0033] It includes an outer shell 1, and a connection and positioning mechanism is provided at the bottom of the outer shell 4. The connection and positioning mechanism is used to connect and position the PCB board 23. Pins 6 are arranged at intervals in the outer shell. The pins 6 have a welding end 7 extending from the bottom of the outer shell and an elastic contact portion 8 protruding from the insertion gap. The welding end is connected to the PCB board 2.

[0034] With this connector structure, only one connector is needed to connect two perpendicular PCBs, saving costs. In practice, simply solder the two PCBs to the soldering terminals and then solder the elastic contact portion to the PCBs. (When used with a matching board-to-board connection device, the elastic contact portion can also provide contact and connection.)

[0035] Specifically, a plurality of needle slots 9 for installing pins are arranged at intervals in the outer shell. One side of the needle slot 9 has a notch 10 for the elastic contact portion to extend out, and the bottom of the needle slot has a through hole 11 for the welding end to extend out.

[0036] In this embodiment, the pin slot design allows for precise positioning of the pin within the connector, enabling an interference fit between the pin and the slot, improving installation stability. The notch allows the flexible contact portion to extend freely, accommodating PCBs of varying thicknesses, ensuring reliable connection with the PCB and increasing the versatility and flexibility of the connection device. The through-hole facilitates direct extension of the soldering terminal to connect to the PCB, simplifying the soldering process and improving production efficiency.

[0037] Specifically, the connection and positioning mechanism includes a positioning column 12, a positioning plate 13 and a connecting hook 14. The positioning column is inserted into a positioning hole 15 connected to the second PCB board. The positioning plate and the connecting hook pass through the connecting groove 16 on the second PCB board 23, and the connecting hook can be hooked on the second PCB board after passing through the connecting groove.

[0038] In this embodiment, the positioning posts and positioning plate ensure accurate alignment and stable placement of PCB 2. The design of the connecting hook not only facilitates quick installation of PCB 2, but also effectively prevents the PCB from loosening or falling off when subjected to external forces, thereby improving the connection stability of the PCB.

[0039] The present application also provides a board-to-board connection device, comprising:

[0040] The bracket includes a mounting back plate 1 and a base 2, and the base 2 is provided with a mounting cavity 3;

[0041] The connector is installed in the installation cavity, and an insertion gap 5 for inserting a PCB board is left between the connector and the installation backplane, and the elastic contact portion is in contact connection with the PCB board.

[0042] By adopting the above technical solution, a non-permanent vertical connection between two PCB boards can be achieved, and the floating requirements of the PCB boards can be met.

[0043] The specific operating principle is: PCB board 1 to be connected is inserted into the insertion gap, and the elastic contact portion is used to make contact and connect with PCB board 1, while PCB board 2 is soldered to the soldering end of the pin. The elastic contact portion and PCB board 1 are in contact and connected, which can achieve an up and down floating connection of PCB board 1.

[0044] Specifically, elastic connecting feet 17 are provided on both sides of the base. The elastic connecting feet 17 include a support rod 18 connected to the base and a tilt rod 19 connected to the support rod. The top of the tilt rod is provided with a clamping groove 20 for clamping the two ends of the PCB board.

[0045] In this embodiment, the elastic connecting legs utilize their inherent elasticity to clamp PCB 2, further enhancing the connection stability of PCB 2. The clamping grooves securely hold PCB 2, further enhancing the security and stability of the connection. This design also facilitates on-site installation and maintenance, allowing for easy assembly and disassembly without the need for additional tools.

[0046] Specifically, corresponding fixing holes 21 are provided on the PCB board 1 and the mounting back plate.

[0047] The fixing holes are used to fix the PCB board and the mounting backplane.

[0048] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
