[0031] Embodiment 1

[0032] According to the attached Figure 1-4 As shown, the embodiment of the utility model provides a conference broadcast signal stabilization device, comprising:

[0033] The repeater body 100 is used to enhance and stabilize the conference broadcast signal;

[0034] The limiting assembly 200 is used to limit and fix the cable plug inserted into the jack on the repeater body 100. The limiting assembly 200 includes a limiting plate 201 arranged at the end of the repeater body 100, and a plurality of limiting openings 202 equidistantly arranged on the surface of the limiting plate 201 and corresponding to the jack. The inner side wall of the limiting opening 202 is provided with a strip groove 203. A bidirectional screw 204 extending to the upper surface of the limiting plate 201 is rotatably arranged on the inner wall of the strip groove 203, and a rotating block 205 for rotating the bidirectional screw 204 is fixed at the top of the bidirectional screw 204. Two symmetrical clamping plates 206 are slidably arranged on the inner wall of the strip groove 203, and arc-shaped rubber pads 207 for protecting the plug are fixed on the opposite surfaces of the two clamping plates 206.

[0035] The inner top wall and the inner bottom wall of the limiting opening 202 are fixed with a limiting slide bar 208, and the upper surfaces of the two clamping plates 206 are provided with sliding holes slidably connected to the outer surfaces of the limiting slide bar 208, which effectively ensures the stability of the clamping plates 206 during the up and down movement.

[0036] The surfaces of the two clamping plates 206 are provided with threaded holes threadedly connected to the outer surface of the bidirectional screw 204, and the inner top wall of the strip groove 203 is provided with a rotating hole extending to the upper surface of the limit plate 201 for the bidirectional screw 204 to rotate, so as to facilitate the rotation of the bidirectional screw 204 through the rotating block 205.

[0037] In this embodiment, by providing a limit assembly 200, during the actual installation and use of the repeater, after the cable connector is inserted into the socket, the rotating block 205 corresponding to the socket can be rotated, and the rotation of the rotating block 205 drives the rotation of the bidirectional screw 204, and the rotation of the bidirectional screw 204 drives the two clamping plates 206 to move toward the middle at the same time, and effectively clamps and fixes the surface of the cable connector, and can effectively protect the connector under the action of two arc-shaped rubber pads 207 while increasing the friction between the connector surface and the surface of the clamping plate 206, thereby effectively solving the defect of the prior art that the cable connector and the socket of the repeater cannot be effectively fixed.

[0038] Embodiment 2

[0039] On the basis of the first embodiment, and different from the first embodiment,

[0040] A conference broadcast signal stabilization device, further comprising:

[0041] The locking assembly 300 is used to lock and fix the positioned plug.

[0042] The locking assembly 300 includes a rectangular box 301 symmetrically fixed on both side surfaces of the repeater body 100 , and two rectangular telescopic columns 302 fixedly connected to both side surfaces of the limiting plate 201 .

[0043] A rectangular opening is formed at the end of the rectangular box 301 , and the outer surface of the rectangular telescopic column 302 is slidably connected to the inner wall of the rectangular opening.

[0044] A threaded column 303 is rotatably provided on the inner wall of the rectangular box 301 , and a cylindrical threaded groove 304 threadedly connected to the outer surface of the threaded column 303 is provided at the end of the rectangular telescopic column 302 .

[0046] In this embodiment, through the locking assembly 300, after the cable connector is effectively limited and fixed, the two rotating knobs 305 can be rotated at the same time. The rotation of the rotating knob 305 drives the threaded column 303 to rotate. The rotation of the threaded column 303 drives the rectangular telescopic column 302 to move toward the inside of the rectangular box 301 under the action of the cylindrical thread groove 304, thereby driving the limiting plate 201 to move toward the direction close to the repeater body 100, so that the fixed connector can be more tightly connected to the socket, further solving the defect of the prior art that the cable connector and the socket of the repeater cannot be effectively fixed.
