Technical Field

[0001] The utility model belongs to the technical field of channel expansion, and in particular relates to a power amplifier which is small in size and convenient for channel expansion. Background Art

[0002] An IU chassis refers to a chassis designed specifically for high-power modular electronic products in accordance with certain standards. The IU chassis must achieve strict electronic shielding effects.

[0003] However, the existing IU chassis needs to connect more wiring harnesses, and the existing wiring harness connectors are often a known number, which may lead to insufficient connectors when more wiring harnesses need to be connected. Therefore, a converter is needed at this time, which is more troublesome.

[0004] In view of this, the present utility model is proposed. Summary of the invention

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0006] A power amplifier with a small volume and convenient for channel expansion comprises an IU chassis body, a control component and a main plug hole are arranged on the front side of the IU chassis body, a rectangular groove is provided on the side of the main plug hole close to the control component, a mounting plate is arranged on the front side of the rectangular groove on the front side of the IU chassis body, a plurality of rubber doors equidistantly distributed are arranged on the mounting plate, a plurality of first rectangular notches equidistantly distributed are arranged in the rectangular groove of the main plug hole, a sliding mechanism is arranged in the inner cavity of each of the first rectangular notches, the sliding mechanism comprises two folding slide grooves, a moving mechanism is arranged in the inner cavity of the first rectangular notch, and the moving mechanism comprises a plurality of moving blocks. When the wiring harness is plugged into the main plug-in hole, the wiring harness will be able to squeeze the trapezoidal block and move with the assistance of the sliding mechanism. When the slide bar moves to a certain position, the trapezoidal block will be able to squeeze the moving block and move back and forth, so that the moving block drives the secondary plug-in hole to hit the rubber door through the connecting rod, so that the secondary plug-in hole is exposed to the outside. Therefore, when the wiring harness needs to be continued to be plugged in, the wiring harness can be plugged into the secondary plug-in hole. The above steps are arranged on the secondary plug-in hole, so when a wiring harness is plugged into one of the secondary plug-in holes, the other secondary plug-in hole will be able to be exposed, thereby realizing the expansion of the plug-in hole on the IU chassis body.

[0007] As a preferred embodiment of the utility model, the two folding slides are respectively opened on the two opposite side walls of the second rectangular slot cavity, the two folding slides are symmetrical to each other, and the two folding slide cavities are slidably installed with a slide bar, and the two ends of the slide bar are respectively slidably connected to the two folding slide cavities. The components and installation positions of the sliding mechanism are driven, wherein the sliding mechanism is composed of a folding slide and a slide bar, and the middle of the folding slide is inclined to the rectangular slot, and the two sides are vertically distributed in a spatially staggered manner.

[0008] As a preferred embodiment of the utility model, a connecting rod is fixedly installed at the front end of each slide bar, and a trapezoidal block is fixedly installed at the end of each connecting rod away from the slide bar. The installation position and components of the slide bar are driven, so when the trapezoidal block moves, the slide bar can be driven to move through the connecting rod.

[0009] As a preferred embodiment of the utility model, each of the moving blocks is equidistantly distributed and parallel to each other, and each of the moving blocks slides forward and backward in the second rectangular notch. When the slide bar moves to a certain position, the trapezoidal block can squeeze the moving block to move forward and backward.

[0010] As a preferred embodiment of the utility model, a connecting rod is fixedly installed on one side wall of each moving block away from the sliding mechanism, a secondary plug hole is fixedly installed on one side wall of the connecting rod away from the moving block, and a notch is provided on one side wall of the secondary plug hole away from the connecting rod. This ensures that when the moving block moves, the moving block drives the secondary plug hole to hit the rubber door through the connecting rod.

[0011] As a preferred embodiment of the utility model, a return spring is fixedly installed on a side wall of each moving block away from the rectangular notch, and each return spring is fixedly connected to the inner wall of the rectangular slot opened on the IU chassis body, ensuring that when the main plug-in hole is taken out, the secondary plug-in hole can be reset and stored back.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] According to the utility model, when the wiring harness is plugged into the main plug-in hole, the wiring harness will be able to squeeze the trapezoidal block and move with the assistance of the sliding mechanism. When the slide bar moves to a certain position, the trapezoidal block will be able to squeeze the moving block and move forward and backward, so that the moving block drives the auxiliary plug-in hole to hit the rubber door through the connecting rod, so that the auxiliary plug-in hole is exposed to the outside. Therefore, when it is necessary to continue to plug the wiring harness, the wiring harness can be plugged into the auxiliary plug-in hole. The auxiliary plug-in hole is provided with the above steps, so when a wiring harness is plugged into one of the auxiliary plug-in holes, the other auxiliary plug-in hole will be able to be exposed, thereby realizing the expansion of the plug-in hole on the IU chassis body.

When the wiring harness is plugged into the main plug hole 3, the wiring harness will be able to squeeze the trapezoidal block 8 and move with the assistance of the sliding mechanism. When the slide bar 16 moves to a certain position, the trapezoidal block 8 will be able to squeeze the moving block 10 to move forward and backward, so that the moving block 10 drives the secondary plug hole 13 to hit the rubber door 5 through the connecting rod 12, so that the secondary plug hole 13 is exposed to the outside at this time. Therefore, when it is necessary to continue to plug the wiring harness, the wiring harness can be plugged into the secondary plug hole 13, and the above steps are arranged on the secondary plug hole 13, so when a wiring harness is plugged into one of the secondary plug holes 13, the other secondary plug hole 13 will be able to be exposed, thereby realizing the expansion of the plug hole on the IU chassis body 1.

[0027] like Figures 1 to 3 As shown, further, a connecting rod 17 is fixedly installed at the front end of each slide bar 16, and a trapezoidal block 8 is fixedly installed at one end of each connecting rod 17 away from the slide bar 16. In this configuration, the installation position and components of the slide bar 16 are driven, so when the trapezoidal block 8 moves, the slide bar 16 can be driven to move by the connecting rod 17.

The shaping block 8 will be able to squeeze the moving block 10 to move forward and backward, so that the moving block 10 drives the auxiliary plug hole 13 to hit the rubber door 5 through the connecting rod 12, so that the auxiliary plug hole 13 is exposed to the outside at this time. Therefore, when it is necessary to continue to plug the wiring harness, the wiring harness can be plugged into the auxiliary plug hole 13, and the auxiliary plug hole 13 is provided with the above steps, so when a wiring harness is plugged into one of the auxiliary plug holes 13, the other auxiliary plug hole 13 will be able to be exposed, thereby realizing the expansion of the plug hole on the IU chassis body 1.
