Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically to an anti-interference shielded wire harness for security monitoring. Background Technology

[0002] Anti-interference shielded cable harnesses used in security monitoring systems are designed to ensure the stability and reliability of signal transmission in complex electromagnetic environments. These cable harnesses are typically used to connect cameras, sensors, control equipment, etc., ensuring that video, audio, and data signals are not affected by external electromagnetic or radio frequency interference.

[0003] While existing anti-interference shielded wire harnesses can maintain the stability and reliability of signal transmission during use, when used in the external environment, the connection points between the anti-interference shielded wire harnesses are directly exposed to the outside world and the two are only in a plug-in connection relationship. When subjected to external interference, the connection points are easily damaged or disconnected, which may affect the normal operation of the work. Utility Model Content

[0004] The purpose of this invention is to provide an anti-interference shielded wire harness for security monitoring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference shielded wire harness for security monitoring, comprising a mounting plate and an anti-interference shielded wire harness body, wherein the top of the mounting plate is provided with a mounting hole, a protective shell is fixedly connected to the top of the mounting plate, a fixing mechanism is provided inside the protective shell, a column is fixedly connected to the bottom of the inner side of the protective shell, an arc-shaped receiving plate is fixedly connected to the top of the column, and a protrusion is fixedly connected to the outer wall of the protective shell.

[0006] As a further preferred embodiment of this technical solution, a movable plate is slidably connected to the inner wall of the protective shell, a first spring is fixedly connected to the top of the movable plate, and a top plate is fixedly connected to the end of the first spring away from the movable plate.

[0007] As a further preferred embodiment of this technical solution, a connecting rod is fixedly connected to the bottom end of the movable plate, and an arc-shaped pressing plate is fixedly connected to the bottom end of the connecting rod. The arc-shaped pressing plate is located directly above the arc-shaped receiving plate, and a fixing block is fixedly connected to the outer wall of the top plate.

[0008] As a further preferred embodiment of this technical solution, the outer wall of the fixing block is provided with a threaded hole, and the outer wall of the protrusion is penetrated and threadedly connected with a fixing bolt.

[0009] As a further preferred embodiment of this technical solution, the outer wall of the protective shell is provided with an auxiliary mechanism, and a connecting pipe is connected through and fixedly connected to the outer wall of the protective shell, and a connecting block is fixedly connected to the inner wall of the connecting pipe.

[0010] As a further preferred embodiment of this technical solution, a rotating rod is rotatably connected to the inner wall of the connecting block, a connecting arm is fixedly connected to the outer wall of the rotating rod, and a rotating roller is rotatably connected to the inner wall of the connecting arm.

[0011] As a further preferred embodiment of this technical solution, a second spring is fixedly connected to the outer wall of the connecting arm, and the end of the second spring away from the connecting arm is fixedly connected to the inner wall of the connecting pipe.

[0012] This utility model provides an anti-interference shielded wire harness for security monitoring, which has the following beneficial effects:

[0013] (1) This utility model closes the top plate by pressing it down. The top plate moves the moving plate inside the protective shell through the first spring. The moving plate moves the arc-shaped pressing plate down until the bottom of the top plate is in contact with the top of the protective shell. The fixing block is inserted into the inside of the protrusion. The fixing bolt is rotated and passes through the protrusion and is threaded into the threaded hole to fix the fixing block inside the protrusion. At this time, the first spring is compressed. The first spring applies a pressing force to the moving plate by its own elasticity, which in turn drives the arc-shaped pressing plate to fix the anti-interference shielding wire harness body, maintain the stability of the anti-interference shielding wire harness body, and prevent it from being detached due to external interference.

[0014] (2) In this utility model, the connecting arm is squeezed and the rotating rod rotates while the second spring is squeezed. The second spring is squeezed and its own elasticity applies a support force in the opposite direction to the connecting arm, thereby driving the rotating roller to fit tightly against the outer wall of the anti-interference shielding wire harness body. Relying on the multiple connecting arms around it, the anti-interference shielding wire harness body inside the connecting pipe is corrected to prevent the anti-interference shielding wire harness body from bending.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an anti-interference shielded wire harness for security monitoring includes a mounting plate 1 and an anti-interference shielded wire harness body 5. The top of the mounting plate 1 has a mounting hole 2. A protective shell 3 is fixedly connected to the top of the mounting plate 1. A fixing mechanism 6 is provided inside the protective shell 3. A column 65 is fixedly connected to the bottom of the inside of the protective shell 3. An arc-shaped receiving plate 66 is fixedly connected to the top of the column 65. A protrusion 69 is fixedly connected to the outer wall of the protective shell 3.

[0022] The inner wall of the protective shell 3 is slidably connected to a movable plate 62, the top of the movable plate 62 is fixedly connected to a first spring 61, and the end of the first spring 61 away from the movable plate 62 is fixedly connected to a top plate 4.

[0023] The top plate 4 can shield the protective housing 3, thereby preventing external objects from interfering with the internal wiring harness.

[0024] Among them, the bottom end of the movable plate 62 is fixedly connected to the connecting rod 63, the bottom end of the connecting rod 63 is fixedly connected to the arc-shaped pressing plate 64, the arc-shaped pressing plate 64 is located directly above the arc-shaped receiving plate 66, and the outer wall of the top plate 4 is fixedly connected to the fixing block 67.

[0025] The arc-shaped pressing plate 64 and the arc-shaped receiving plate 66 can fix the wire harness between them, thereby preventing the wire harness from coming loose.

[0026] The outer wall of the fixing block 67 is provided with a threaded hole 68, and the outer wall of the protrusion 69 is connected by a fixing bolt 610.

[0027] The fixing bolt 610 is threaded into the threaded hole 68, thereby fixing the fixing block 67 inside the protrusion 69.

[0028] The outer wall of the protective shell 3 is provided with an auxiliary mechanism 7, and a connecting pipe 71 is connected through and fixedly connected to the outer wall of the protective shell 3. A connecting block 72 is fixedly connected to the inner wall of the connecting pipe 71.

[0029] The auxiliary mechanism 7 can support the wire harness, thereby preventing the wire harness from bending at the connection point.

[0030] The inner wall of the connecting block 72 is rotatably connected to a rotating rod 73, the outer wall of the rotating rod 73 is fixedly connected to a connecting arm 74, and the inner wall of the connecting arm 74 is rotatably connected to a rotating roller 76.

[0031] The rotating roller 76 directly contacts the wire harness, thereby preventing excessive friction between the roller and the wire harness, which could affect the normal replacement of the wire harness.

[0032] A second spring 75 is fixedly connected to the outer wall of the connecting arm 74, and the end of the second spring 75 away from the connecting arm 74 is fixedly connected to the inner wall of the connecting pipe 71.

[0033] The second spring 75, when subjected to external compressive force, will exert a supporting force in the opposite direction on the connecting arm 74 by relying on its own elasticity.

[0034] This utility model provides an anti-interference shielded wire harness for security monitoring, and its working principle is as follows:

[0035] In use, the anti-interference shielding harness body 5 to be connected is passed through the connecting pipe 71 and enters the interior of the protective shell 3. During the movement, the anti-interference shielding harness body 5 compresses the connecting arm 74. The compression of the connecting arm 74 causes the rotating rod 73 to rotate, while simultaneously compressing the second spring 75. The compression of the second spring 75, relying on its own elasticity, applies a counter-direction supporting force to the connecting arm 74, thereby causing the rotating roller 76 to fit tightly against the outer wall of the anti-interference shielding harness body 5. Relying on the surrounding multiple connecting arms 74, the anti-interference shielding harness body 5 inside the connecting pipe 71 is corrected to prevent bending. The anti-interference shielding harness body 5 located inside the protective shell 3 is positioned on the arc-shaped receiving plate 66. Above, the two are connected and pressed down to close the top plate 4. The top plate 4 is driven by the first spring 61 to move the moving plate 62 inside the protective shell 3. The moving plate 62 drives the arc-shaped pressing plate 64 to move downward until the bottom of the top plate 4 is in contact with the top of the protective shell 3. The fixing block 67 is inserted into the protrusion 69. The fixing bolt 610 is rotated and passes through the protrusion 69 and is threaded into the threaded hole 68, fixing the fixing block 67 inside the protrusion 69. At this time, the first spring 61 is compressed. The first spring 61 applies downward pressure to the moving plate 62 by its own elastic force, thereby driving the arc-shaped pressing plate 64 to fix the anti-interference shielding wire harness body 5, maintaining the stability of the anti-interference shielding wire harness body 5 and preventing it from detaching due to external interference.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
