Description

Technical Field

[0001] This utility model relates to multi-core connectors, and more particularly to a solder plate type multi-core connector assembly. Background Technology

[0002] Many existing electronic products use multi-pin connectors to transmit current or signals. Multi-pin connectors are generally divided into wire bonding type and solder board type. Solder board type multi-pin connector assemblies are widely used in scenarios that require multiple line connections. All pins of solder board type multi-pin connector assemblies are directly soldered to the PCB board, and the overall space occupied is small. However, the shortcomings of existing solder board type multi-pin connector assemblies are as follows: Solder board type multi-pin connector assemblies have many pins. If they are directly soldered to a single PCB board, the pins in the middle part of the solder board type multi-pin connector assembly cannot be led out through the copper trace of the PCB board due to electrical distance limitations. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a solder plate type multi-core connector assembly.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is: a solder plate type multi-core connector assembly, including a multi-core connector and a PCB board, the PCB board including a first PCB board and a second PCB board; the rear end face of the multi-core connector is provided with a number of internal pins and a number of external pins, the internal pins and external pins are sequentially connected to the first PCB board and the second PCB board, and the upper end face of the first PCB board is fixedly connected to the second PCB board.

[0005] The first PCB board has several internal clearance holes and external soldering holes, and the second PCB board has several internal soldering holes and external clearance holes; the internal pins pass through the internal clearance holes and are soldered to the internal soldering holes, and the external pins are soldered to the external soldering holes and pass through the external clearance holes.

[0006] Furthermore, both the first PCB board and the second PCB board have an L-shaped structure.

[0007] Furthermore, the upper surface of the first PCB board is spot-welded to the side of the second PCB board.

[0008] Furthermore, the internal clearance hole, the external welding hole, and the internal welding hole are all circular.

[0009] Furthermore, the maximum length between several internal solder holes on the second PCB board is less than the diameter of the internal clearance hole.

[0010] Furthermore, after the first PCB board and the second PCB board are fixedly connected, the pins of the multi-core connector are not lower than the top plane of the second PCB board.

[0011] Furthermore, the second PCB board is fixedly provided with pin headers and sockets for insertion into the first PCB board.

[0012] This utility model discloses a soldering board type multi-core connector assembly. It involves setting external soldering holes and internal clearance holes on a first PCB board, and internal soldering holes and external clearance holes on a second PCB board. The first and second PCB boards are stacked, and the external pins of the soldering board type multi-core connector assembly are soldered to the first PCB board, while the internal pins are soldered to the second PCB board. The first and second PCB boards are then fixedly connected. The internal and external pins of the multi-core connector are staggered with the first PCB board, ensuring that all pins on the soldering board type multi-core connector assembly are directly or indirectly connected to the first PCB board without affecting the electrical distance between pins, allowing the internal pins to pass smoothly through the copper traces of the PCB board.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1:

[0023] like Figure 1-6As shown, a solderable multi-core connector assembly includes a multi-core connector 7 and a PCB board. The PCB board includes a first PCB board 1 and a second PCB board 2. The rear end face of the multi-core connector 7 is provided with a plurality of internal pins and a plurality of external pins at equal intervals. The internal pins and external pins are sequentially connected to the first PCB board 1 and the second PCB board 2. The first PCB board 1 and the second PCB board 2 are both L-shaped structures. The upper end face of the first PCB board 1 is fixedly connected to the second PCB board 2.

[0024] In this embodiment, the length of the second PCB board 2 is less than the length of the first PCB board 1, and the upper end face of the first PCB board 1 is spot-welded to the side of the second PCB board 2; the first PCB board 1 has a plurality of internal clearance holes 3 and external welding holes 4, and the second PCB board 2 has a plurality of internal welding holes 5 and external clearance holes 6.

[0025] The internal pins pass through the internal clearance hole 3 and are soldered to the internal solder hole 5, leading to the outside of the second PCB board 2. The external pins are soldered to the external solder hole 4 and pass through the external clearance hole 6, leading to the outside of the second PCB board 2.

[0026] Among them, the internal pins and internal welding holes 5 are set one-to-one, and the external pins, external welding holes 4 and external welding holes 4 are set one-to-one;

[0027] The internal clearance hole 3, the external welding hole 4, the internal welding hole 5, and the external clearance hole 6 are all circular.

[0028] In this embodiment, the first PCB board 1 has 24 external soldering holes 4 at equal intervals along the circumference, and the center of the 7 internal soldering holes 5 has an internal clearance hole 3. The maximum length between the 7 internal soldering holes 5 on the second PCB board 2, that is, the maximum length of the surface formed by the 7 internal soldering holes 5, is less than the diameter of the internal clearance hole 3, so that the internal pins can pass neatly through the internal clearance hole 3, pass through and solder to the internal soldering hole 5, ensuring a suitable electrical distance between each pin.

[0029] After the first PCB board 1 and the second PCB board 2 are fixedly connected, the pins of the multi-core connector 7 shall not be lower than the top plane of the second PCB board 2.

[0030] The connection process in this embodiment specifically includes the following steps:

[0031] 1. Solder the external pins of the soldering board type multi-core connector assembly to the external soldering holes 4 on the first PCB board 1; so that the internal pins pass through the internal clearance holes 3;

[0032] 2. Place the second PCB board 2 against the upper surface of the first PCB board 1, and connect the internal pins of the soldered multi-core connector to the internal soldering holes 5 on the second PCB board 2; so that the external pins are led to the outside of the second PCB board 2 through the external clearance holes 6;

[0033] 3. The side of the second PCB board 2 is spot-welded to the top of the first PCB board 1 to achieve electrical connection between the second PCB board 2 and the first PCB board 1.

[0034] This invention involves setting external soldering holes 4 and internal clearance holes 3 on a first PCB board 1, and setting internal soldering holes 5 and external clearance holes 6 on a second PCB board 2. The first PCB board 1 and the second PCB board 2 are stacked together, and the external pins of the soldering board type multi-core connector assembly are soldered to the first PCB board 1, and the internal pins are soldered to the second PCB board 2. The first PCB board 1 and the second PCB board 2 are electrically connected. The internal and external pins of the multi-core connector 7 are staggered with the first PCB board 1, so that all pins on the soldering board type multi-core connector assembly are directly or indirectly connected to the first PCB board 1 without affecting the electrical distance between the pins, and the internal pins can pass smoothly through the copper foil of the PCB board.

[0035] Example 2:

[0036] like Figure 7 As shown, in this embodiment, a pin header and nut header 8 are fixedly provided on the second PCB board 2 to be inserted into the first PCB board 1. In this embodiment, each pin header and nut header 8 has 8 pins in a single row, and the spacing between them is 2.54mm.

[0037] It should be noted that several pin headers are vertically soldered to the first PCB board 1, and the female headers are soldered to the second PCB board 2. The position and spacing of the female header holes are consistent with those of the pin headers. The pin headers of the first PCB board 1 are aligned with the female header holes of the second PCB board 2, and the pin headers are vertically inserted into the female headers to achieve electrical connection between the first PCB board 1 and the second PCB board 2.

[0038] In summary, the second embodiment in this specification mainly describes the differences from the first embodiment. The same or similar parts between the first embodiment and other embodiments can be referred to each other.

[0039] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
