Description

Technical Field

[0001] This utility model relates to the field of signal line technology, specifically to a tensile and bending resistant monitoring instrument signal line. Background Technology

[0002] A monitoring signal cable is a special cable used to transmit video, audio, data, or control signals collected by monitoring equipment (such as cameras, sensors, data acquisition instruments, etc.).

[0003] Currently, the structure of the monitoring instrument signal cable is simple and lacks external protection. The outer protective layer of the monitoring instrument signal cable is easily damaged by external cutting. In addition, the monitoring instrument signal cable is prone to right-angle bends during bending, which can easily cause the internal wire core to break or be damaged. Furthermore, the tensile strength of the monitoring instrument signal cable is poor, and the internal wire core may be pulled apart under excessive force. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tensile and bending resistant monitoring signal cable with an external protective structure, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a tensile and bending resistant monitoring instrument signal cable, including a signal cable, the signal cable being sleeved with multiple protective rings, with rubber sleeves installed between adjacent protective rings, and locking sleeves installed on the outermost protective rings. Both ends of the signal cable are provided with annular grooves, and positioning rings are installed in the annular grooves. The opening of one end of the locking sleeve narrows inward and contacts the outer ring surface of the positioning ring. The positioning sleeves are provided with multiple positioning holes in annular structure, and positioning pins that are inserted into the positioning rings are provided in the positioning holes.

[0006] As a preferred technical solution, the outer ring of the positioning ring is provided with insertion holes at the positioning holes, one end of the positioning pin is inserted into the insertion hole, the other end of the positioning pin is flush with the outer ring of the positioning ring, and one end of the locking sleeve is threaded with a clamping ring.

[0007] As a preferred technical solution, multiple shock-absorbing blocks are installed on the inner ring surface of the protective ring. The multiple shock-absorbing blocks are evenly distributed in a ring structure. One side of each shock-absorbing block is provided with an arc-shaped surface, which is fitted to the outer ring surface of the signal cable. The shock-absorbing blocks are all made of rubber material.

[0008] As a preferred technical solution, the protective ring, locking sleeve, and positioning ring are all made of engineering plastic materials.

[0009] As a preferred technical solution, both the positioning pin and the clamping ring are made of metal.

[0010] As a preferred technical solution, the outer surface of the positioning ring is flush with the outer surface of the signal wire.

[0011] As a preferred technical solution, a fiber layer is provided on the inner side of the outer wall of the rubber sleeve.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The protective ring and rubber sleeve can provide protection for the signal cable, reducing the probability of the outer protective layer being cut by the outside. When the signal cable is bent, it will drive the protective ring, and the protective rings will abut against each other, so that the signal cable can only bend at an arc angle, avoiding the core breakage caused by right-angle bending. Furthermore, the two ends of the protective ring are fixed to the signal cable by locking sleeves. When it is pulled, the protective ring and rubber sleeve can also provide axial tensile resistance to increase the tensile resistance of the signal cable. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a tensile and bending resistant monitoring signal cable, including a signal cable 1. The signal cable 1 is fitted with multiple protective rings 2, and a rubber sleeve 3 is installed between adjacent protective rings 2. A locking sleeve 4 is installed on the outermost protective ring 2. Both ends of the signal cable 1 are provided with annular grooves, and positioning rings 7 are installed in the annular grooves. The opening of one end of the locking sleeve 4 is narrowed inward and is in contact with the outer ring surface of the positioning ring 7. The positioning sleeve is provided with multiple positioning holes in an annular structure, and each positioning hole is provided with a positioning post 6 that is inserted into the positioning ring 7.

[0023] In this embodiment, the outer ring surface of the positioning ring 7 is provided with insertion holes 9 at the positioning holes. One end of the positioning pin 6 is inserted into the insertion hole 9, and the other end of the positioning pin 6 is flush with the outer ring surface of the positioning ring 7. One end of the locking sleeve 4 is threaded with a clamping ring 5.

[0024] In this embodiment, multiple shock-absorbing blocks are installed on the inner ring surface of the protective ring 2. The multiple shock-absorbing blocks are evenly distributed in a ring structure. One side of each shock-absorbing block is provided with an arc-shaped surface, which is fitted to the outer ring surface of the signal cable 1. The shock-absorbing blocks are all made of rubber material. The shock-absorbing blocks can center the signal cable on the protective ring. When the signal cable is bent, the rubber blocks can be squeezed, and an annular channel is formed between the signal cable, the protective ring, and the rubber sleeve, avoiding friction with the inner wall of the protective ring or the rubber sleeve during the bending process.

[0025] In this embodiment, the protective ring 2, the locking sleeve 4, and the positioning ring 7 are all made of engineering plastic material, which avoids electrical conductivity and increases safety.

[0026] In this embodiment, both the positioning pin 6 and the clamping ring 5 are made of metal, which increases the robustness and can better restrict the locking sleeve on the positioning ring.

[0027] In this embodiment, the outer surface of the positioning ring 7 is flush with the outer surface of the signal wire 1, so that the locking sleeve can be smoothly fitted onto the signal wire through the positioning ring, avoiding obstruction.

[0028] In this embodiment, a fiber layer is provided on the inner side of the outer wall of the rubber sleeve 3. The fiber layer increases the strength of the rubber sleeve and can better protect it from axial tension.

[0029] In use, the rubber sleeve and protective ring can be fitted over the outside of the signal cable. After being moved into place, the locking sleeve can be located at both ends of the signal cable and set opposite to the positioning ring. At this time, the positioning pin is prepared. The positioning pin can be inserted into the socket through the positioning hole, and the clamping ring is rotated to move the clamping ring outward along the thread until it presses on the outer end face of the positioning pin, which can limit the positioning pin and prevent the positioning pin from falling out. It also completes the connection between the protective ring and the rubber sleeve and the signal cable.

[0030] The protective rings and rubber sleeves provide external protection for the signal cable, reducing the probability of the outer protective layer being cut. When the signal cable bends, the protective rings move together, causing them to press against each other, ensuring that the signal cable can only bend at an arc angle, avoiding wire core breakage caused by right-angle bends. Furthermore, the two ends of the protective rings are fixed to the signal cable by locking sleeves. When subjected to tension, the protective rings and rubber sleeves also provide axial tensile resistance, increasing the tensile strength of the signal cable.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
