Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically to a modular electrical connector. Background Technology

[0002] Modular electrical connectors are standardized interface components designed to enable power, signal, or data transmission in electronic devices or systems. Their modular structure allows for the rapid connection, disconnection, and maintenance of cables or modules of different specifications, thereby enhancing system flexibility, scalability, and reliability.

[0003] Most existing electrical connectors are directly soldered onto the motherboard PCB. When some electrical connectors are large, direct soldering onto the motherboard PCB will occupy a large area of ​​the motherboard PCB, which may result in insufficient space or an excessively large size on the motherboard PCB, which is not conducive to the lightweight design of electronic products. In addition, when some electrical connectors are large, their flatness may not meet the requirements of the motherboard PCB soldering process, which may lead to the electrical connector not being able to be soldered onto the motherboard PCB. Summary of the Invention

[0004] The main objective of this invention is to provide a modular electrical connector that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A modular electrical connector includes a connector body and an adapter assembly for connecting to a host PCB board. The connector body is composed of a plastic body and a metal shell, which are interlocked to form a card-insertion cavity. The plastic body has a terminal group, one end of which extends outward to form a terminal soldering pin. The adapter assembly is connected to the terminal soldering pin. The adapter assembly includes a connecting wire, one end of which has a plug-in terminal for connecting to the host PCB board, and the other end of which is soldered to an adapter PCB board.

[0007] In the above description, a more preferred embodiment is that the terminal group includes a detection end bullet and a signal end bullet, and the signal end bullet and the detection end bullet are integrally formed.

[0008] In the above description, a more preferred embodiment is that the edge of the metal shell extends outward to form several mounting holes, the edge of the metal shell is folded inward to form several locking blocks, and one end of the metal shell is cut to form two locking springs.

[0009] In the above description, a more preferred embodiment is that the plastic body is provided with a clamping spring piece integrally formed with the plastic body, and the two sides of the plastic body are provided with assembly slots and outer shell slots.

[0010] In the above description, a more preferred embodiment is that a solder pad is provided on one side of the adapter PCB board, and a metal rod is soldered onto the solder pad.

[0011] In the above description, a more preferred embodiment is that the adapter PCB board is provided with assembly positioning holes.

[0012] In the above description, a more preferred embodiment is that the connecting wire is an FFC flexible flat cable.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The new electrical connector features a modular design, allowing it to be adapted to different host PCBs by replacing different specifications of FFC flexible flat cables. This reduces the development cost of electrical connectors, and the same host PCB can accommodate different specifications of electrical connectors, solving the problem of larger electrical connectors not occupying space on the host PCB.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-8 As shown, a modular electrical connector in this solution includes a connector body 1 and an adapter assembly 2 for connecting to a host PCB board 3. The connector body 1 is composed of a plastic body 11 and a metal shell 12. The plastic body 11 and the metal shell 12 are interlocked to form a card insertion cavity 13 inside, into which a card 4 can be inserted. The plastic body 11 is provided with a terminal group 14. One end of the terminal group 14 extends outward to form a terminal soldering foot 141. The adapter assembly 2 is connected to the terminal soldering foot 141. The adapter assembly 2 includes a connecting wire 21. One end of the connecting wire 21 is provided with a plug-in end 211 for connecting to the host PCB board 3. The other end of the connecting wire 21 is soldered to an adapter PCB board 212. The adapter PCB board 212 is soldered to the terminal soldering foot 141 of the electrical connector.

[0026] In this embodiment, the terminal group 14 includes a detection end bullet piece 142 and a signal end bullet piece 143. The signal end bullet piece 143 and the detection end bullet piece 142 are integrally formed. After the terminal group 14 is formed, it is treated with an anti-corrosion process to extend the service life of the connector.

[0027] To facilitate installation and assembly, the edges of the metal casing 12 extend outward to form several mounting holes 121. During installation, it can be fixed to the chassis through the mounting holes 121. The edges of the metal casing 12 are all folded inward to form several locking blocks 122. One end of the metal casing 12 is cut to form two clamping springs 123. It is assembled with the plastic body 11 through the locking blocks 122 and the clamping springs 123.

[0028] To make the card 4 more stable when inserted into the card insertion cavity 13, the plastic body 11 is provided with a clamping spring 111 integrally formed with the plastic body 11. When in use, the card 4 is inserted into the card insertion cavity 13 and clamped by the clamping spring 111. Assembly slots 112 and outer shell slots 113 are distributed on both sides of the plastic body 11. The plastic body 11 and the metal outer shell 12 are assembled through the assembly slots 112 and the outer shell slots 113.

[0029] To ensure a more secure connection, a solder pad 2122 is provided on one side of the adapter PCB board 212. A metal rod 2121 is soldered onto the solder pad 2122. After soldering with the solder pad 2122, the metal rod 2121 is used to further press the connecting wire 21 to prevent the connecting wire 21 from being pulled up.

[0030] The adapter PCB board 212 is provided with assembly positioning holes 2123. During assembly, it is installed and fixed to the plastic body 11 through the assembly positioning holes 2123.

[0031] For easier assembly, the connecting cable 21 uses an FFC flexible flat cable, which has high flexibility and abrasion resistance, is easy to bend, and has a longer service life. By adjusting the length and bending shape of the FFC flexible flat cable, the electrical connector can be installed in any position inside the host.

[0032] By adopting the above technical solutions, such as Figure 7 and Figure 8 As shown, this invention designs a smaller adapter PCB board 212 as a component of the electrical connector. The electrical contact pins of the electrical connector are soldered to this PCB board. Each pin has a corresponding output solder pad 2122 designed on the PCB board for connection. An FFC flexible flat cable is soldered to the output solder pad 2122 for connection to the corresponding receiving connector on the host PCB board 3. In this way, the function of this electrical connector can be applied to the host PCB board 3. By adjusting the length and shape of the FFC flexible flat cable, the electrical connector can be installed in any position within the host without being directly soldered to the host PCB board 3. Because the size of the corresponding receiving connector on the host PCB board 3 can be made much smaller than the original electrical connector, it occupies much less area on the host PCB board 3 and easily meets the solder pin process requirements of the host PCB board 3.

[0033] Any aspects of this invention not described in detail are well-known to those skilled in the art.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
