Technical Field

[0001] The utility model relates to the technical field related to electronic components, and in particular to a multi-layer PCB circuit board coupler. Background Art

[0002] Electronic components are the basic elements in electronic circuits. They are usually individually packaged and have two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with specific functions. The formation of electronic circuits is inseparable from the help of couplers, such as photoelectric couplers. Photoelectric couplers are an electric-to-optical-to-electrical conversion device that uses light as a medium to transmit electrical signals. In order to better utilize related electronic components, a multi-layer PCB circuit board coupler is particularly needed.

[0003] However, most existing couplers are only well adapted to multi-layer circuits, and when the circuit board is working, the circuit board may stop functioning due to untimely transmission of electrical signals in the circuit board, thereby affecting its working efficiency. Utility Model Content

[0004] The present invention aims to provide a multi-layer PCB circuit board coupler to address the problem of the existing couplers proposed in the above-mentioned background art. Most couplers are well adapted to multi-layer circuits, and when the circuit board is working, the circuit board may stop operating due to untimely transmission of electrical signals in the circuit board, thereby affecting its working efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-layer PCB circuit board coupler, comprising a bottom shell, a coupler mounted on one side surface of the bottom shell, a connecting mechanism provided on one side surface of the coupler, and a fixing mechanism provided on one side surface of the bottom shell;

[0006] The connecting mechanism includes a mounting groove, a fixing groove, a conductive plate, a wiring and a fixing plate. A mounting groove is provided on one side surface of the bottom shell, a fixing groove is provided on one side surface of the mounting groove, a conductive plate is fixedly connected to the inner surface of the fixing groove, a wiring is fixedly connected to one side surface of the bottom shell, and a fixing plate is fixedly connected to the outer surface of the bottom shell.

[0007] Preferably, the mounting groove is opened symmetrically with respect to the central axis of the bottom shell, and the outer wall size of the conductive plate matches the inner wall size of the fixing groove.

[0008] Preferably, the wiring is installed symmetrically with respect to the central axis of the bottom shell, and the fixing groove is opened symmetrically with respect to the central axis of the installation groove.

[0009] Preferably, the fixing mechanism includes a first connecting column, a connecting hole, a connecting shaft, a second connecting column, a cover plate, a bolt, a shift block and a limit groove. The first connecting column is fixedly connected to one side surface of the bottom shell, a connecting hole is provided on one side surface of the first connecting column, a connecting shaft is fixedly connected to the inner side surface of the connecting hole, the second connecting column is fixedly connected to one side surface of the first connecting column, a cover plate is threadedly connected to one side surface of the second connecting column, a bolt is installed on one side surface of the cover plate, a shift block is installed on one side surface of the bolt, and a limit groove is provided on one side surface of the bottom shell.

[0010] Preferably, the outer wall size of the bottom shell matches the outer wall size of the cover plate, and the outer wall size of the first connecting column matches the outer wall size of the second connecting column.

[0011] Preferably, the second connecting column is installed symmetrically with respect to the central axis of the bottom shell, and the inner wall size of the connecting hole matches the outer wall size of the connecting shaft.

[0012] Preferably, the outer wall size of the latch matches the inner wall size of the limiting groove, and the inner wall size of the bottom shell matches the outer wall size of the coupler.

[0013] Compared with the prior art, the present invention has the following advantages: the multi-layer PCB circuit board coupler is provided with a mounting slot, a fixing slot, a conductive plate, a wiring, and a fixing plate. When in use, the pins of the coupler are connected to the conductive plate. At this time, the electrical signal of the circuit board during operation is transmitted to the coupler through the wiring and the conductive plate. Then, the coupler transmits the signal to the circuit board through the conductive plate and the wiring, completing the cycle. The wiring can also pass through the multi-layer circuit board at the same time. When the coupler is installed in the bottom shell, the cover plate is rotated around the connecting axis until the latch on one side of the cover plate is engaged with the limit slot. At this time, the cover plate fixes the coupler to a side surface of the bottom shell so that it is not easily removed. When the coupler needs to be adjusted according to the circuit, the shift block is pressed. At this time, the shift block will pop the latch out of the limit slot, and the cover plate is opened upward, and the coupler can be replaced. This solves the problem of the existing couplers mentioned above. Most couplers are well adapted to multi-layer circuits. When the circuit board is working, the circuit board can stop working due to untimely transmission of electrical signals in the circuit board, thereby affecting its working efficiency.

[0022] Furthermore, the mounting groove 301 is opened symmetrically with respect to the central axis of the bottom shell 1, and the outer wall size of the conductive plate 303 matches the inner wall size of the fixing groove 302. Through the setting of the mounting groove 301, when in use, the mounting groove 301 increases the necessary space for the installation of the coupler 2, and at the same time provides space for the opening of the fixing groove 302.

[0023] Furthermore, the wiring 304 is installed symmetrically with respect to the central axis of the bottom shell 1, and the fixing groove 302 is opened symmetrically with respect to the central axis of the installation groove 301.

When in use, align the first connecting post 401 with the connecting hole 402 opened at one end of the second connecting post 404, and then pass the connecting shaft 403 through the first connecting post 401 and the second connecting post 404. When in use, when the coupler 2 is installed in the bottom shell 1, the cover plate 405 is rotated with the connecting shaft 403 as the center until the latch 406 on one side of the cover plate 405 is snapped into the limiting groove 408. At this time, the cover plate 405 fixes the coupler 2 to one side surface of the bottom shell 1 so that it is not easy to fall off. When the coupler 2 needs to be adjusted according to the circuit, press the shift block 407. At this time, the shift block 407 will pop out the latch 406 from the limiting groove 408, open the cover plate 405 upwards, and then the coupler 2 can be replaced.

Through the setting of the limiting groove 408, when in use, the limiting groove 408 provides the necessary conditions for the fastening of the latch 406, and at the same time will not take up space on the circuit board.

When the coupler 2 needs to be adjusted according to the circuit, press the shift block 407. At this time, the shift block 407 will pop out the latch 406 from the limiting groove 408, open the cover 405 upwards, and then the coupler 2 can be replaced.
