Description

Technical Field

[0001] The utility model belongs to the technical field of circuit boards, and in particular relates to an optical transmission circuit board. Background Art

[0002] At present, the rate and frequency of signal transmission are getting higher and higher, and traditional circuit boards are constantly breaking through the limits of transmission rate and frequency. However, due to the increasingly serious parasitic effects, the transmission rate and frequency of traditional circuit boards are also limited, and it is difficult to fundamentally take the transmission rate and frequency to a higher level. Based on the exploration of optical transmission circuit boards, more and more cases show that optical transmission circuit boards have good advantages such as low energy consumption, high speed, and high bandwidth. Therefore, optical transmission circuit boards have become one of the development directions of new circuit boards. Optical transmission circuit boards need to be connected to plugs for use to receive optical signals and convert them into digital signals required by the measurement and control system.

[0003] However, there are some problems with the prior art: when the existing optical transmission circuit board is in use, an external plug is directly inserted into the interface for data transmission. During subsequent use, the cable connected to the plug is easily pulled and dragged accidentally, resulting in poor contact between the plug and the interface, and even causing the plug to fall off the interface, thereby affecting normal data transmission. Therefore, we propose an optical transmission circuit board. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an optical transmission circuit board, which limits the plug by a stopper lever, thereby preventing the plug from falling off from the interface.

[0005] The utility model is implemented as follows: an optical transmission circuit board comprises a base plate, a circuit board is mounted on the base plate, a connection module is connected between the base plate and the circuit board, an interface is provided on the connection module, a gear lever is provided on the base plate, the gear lever and the base plate are connected by a rotating mechanism, the gear lever can be moved to the front of the interface by the rotating mechanism, and the gear lever can be attached to the surface of the base plate by the rotating mechanism.

[0006] Optionally, the rotating mechanism comprises a block, the block is fixedly mounted on the bottom plate, a circular shaft is rotatably connected to the block, a circular shaft is fixedly connected to a circular rod, and the gear lever can rotate around the circular shaft as the axis.

[0007] Optionally, a sleeve is movably sleeved on the outer surface of the round rod, and the shift rod is fixedly mounted on the sleeve.

[0008] Optionally, a spring is movably sleeved on the outer surface of the round rod, and two ends of the spring are respectively fixedly connected to the round shaft and the sleeve.

[0009] Optionally, the gear lever is configured to be cylindrical, and anti-slip grooves are provided on the gear lever.

[0010] Optionally, a clamping block is fixedly mounted on the base plate, and the shift lever is movably clamped in the clamping block.

[0011] Optionally, a transverse plate is fixedly mounted on the connection module, and a rubber strip is fixedly mounted on the transverse plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting a lever on the bottom plate, when in use, after the staff inserts the plug into the interface, the lever can be rotated 90 degrees through the rotating mechanism to make it fit on the plug. Figure 3 As shown, the plug is limited in position, which prevents the plug from having poor contact with the interface or falling off the interface due to the cable connected to it being pulled and dragged, thereby ensuring the stability of the plug and making data transmission smoother.

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, an optical transmission circuit board provided by an embodiment of the utility model includes a base plate 1, a circuit board 2 is mounted on the base plate 1, a connection module 3 is connected between the base plate 1 and the circuit board 2, an interface 5 is provided on the connection module 3, a gear lever 4 is provided on the base plate 1, the gear lever 4 is connected to the base plate 1 through a rotating mechanism, the gear lever 4 can be moved to the front of the interface 5 through the rotating mechanism, and the gear lever 4 can be attached to the surface of the base plate 1 through the rotating mechanism.

[0022] Furthermore, the rotating mechanism includes a block 6, which is fixedly mounted on the bottom plate 1, a round shaft 7 is rotatably connected to the block 6, a round rod 8 is fixedly connected to the round shaft 7, and the gear lever 4 can rotate around the round shaft 7. The gear lever 4 can be rotated to the front of the interface 5 through the round shaft 7, and can also be attached to the surface of the bottom plate 1 through the rotation of the round shaft 7.

[0023] Furthermore, the outer surface of the round rod 8 is movably sleeved with a sleeve 9, and the lever 4 is fixedly mounted on the sleeve 9. The lever 4 can adjust the relative position with the round rod 8 through the sleeve 9, so that the rotation radius of the lever 4 can be adjusted to ensure that its rotation is not blocked by the plug inserted into the interface 5.

[0024] Furthermore, a spring 11 is movably sleeved on the outer surface of the round rod 8, and the two ends of the spring 11 are respectively fixedly connected to the round shaft 7 and the sleeve 9. Through the design of the spring 11, when the lever 4 rotates and fits on the plug, the spring 11 will be in a stretched state, and due to the elastic recovery effect of the spring 11, the sleeve 9 and the lever 4 will be pulled, so that the lever 4 can fit closely on the surface of the plug.

[0025] Further, the lever 4 is set to be cylindrical, and the lever 4 is provided with anti-skid patterns 12. The design of the anti-skid patterns 12 can increase the friction between the lever 4 and the plug, so that the lever 4 is more stable when it is attached to the surface of the plug.

[0026] Further, a clamping block 13 is fixedly mounted on the bottom plate 1, and the gear lever 4 is movably clamped in the clamping block 13. Through the design of the clamping block 13, the gear lever 4 can be limited when the gear lever 4 is not in use, thereby reducing its occupied space.

[0027] Furthermore, a horizontal plate 14 is fixedly mounted on the connection module 3, and a rubber strip 10 is fixedly mounted on the horizontal plate 14. Due to the design of the rubber strip 10, when the plug is inserted into the interface 5, the rubber strip 10 will be squeezed, and due to the elastic force of the rubber strip 10, the plug will also be squeezed, thereby further improving the stability of the plug in the interface 5.

[0028] During use, after the staff inserts the plug into the interface 5, the rubber strip 10 will be squeezed. Due to the elastic force of the rubber strip 10, the plug will also be squeezed, thereby improving the stability of the plug in the interface 5. Then the lever 4 can be taken out of the block 13 and the lever 4 can be rotated to make the sleeve 9 and the round rod 8 rotate ninety degrees around the round axis 7, and stretch the spring 11. Then the lever 4 is released. At this time, due to the elastic recovery effect of the spring 11, the sleeve 9 will drive the lever 4 to move closer to the block 6, so that the lever 4 fits tightly to the surface of the plug, thereby limiting the plug and preventing the plug from having poor contact with the interface 5 or falling off from the interface 5 due to the pulling and dragging of the cable connected to it, thereby ensuring the stability of the plug and making data transmission smoother.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
