Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to an environmentally friendly cable. Background Art

[0002] A cable is a conductor used to transmit electrical energy or signals, usually consisting of one or more conductors (usually metal wires) surrounded by insulating material and usually a protective outer sheath. Cables are widely used in modern electrical and communication systems.

[0003] Cable connection is a basic operation in electrical engineering. It involves the process of reliably connecting the ends of one or more cables to other cables. For example, when the existing cable length is not enough to cover the required distance, multiple cable segments can be connected to achieve the required total length; or when a cable segment is damaged or aged and needs to be replaced, a new cable segment can be connected to repair the fault. Correct cable connection can not only ensure the safe and stable operation of the circuit, but also extend the service life of the cable.

[0004] Existing multi-core cable connections usually only use insulating tape to connect the core wires. Although this method can provide a certain degree of physical protection and insulation, it is not ideal. The insulating tape is easily damaged, causing direct contact between different core wires, thereby causing signal interference, resulting in signal transmission distortion or interruption, affecting the normal operation of the system; if the distance between the core wires is too close, it will also reduce the coupling between the wires, causing mutual interference between signals. Summary of the invention

[0005] Technical problem to be solved: The present invention provides an environmentally friendly cable that can solve the above-mentioned problems.

[0006] Technical solution: In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an environmentally friendly cable, comprising cable one, cable two and a connecting mechanism connected between cable one and cable two; the connecting mechanism comprises two primary connecting components respectively sleeved on cable one and cable two and a secondary connecting component jointly sleeved on cable one and cable two; when working, the two primary connecting components are docked to connect cable one and cable two and maintain a certain distance between the multiple core wires at the connection between cable one and cable two; the secondary connecting component is sleeved on the outside of the two primary connecting components.

[0007] As a preferred technical solution of the present invention, the first-level connecting assembly includes a clamping sleeve, a support plate and a sliding rod evenly connected between the clamping sleeve and the support plate in the circumferential direction, the sliding rod is axially slidingly connected in the clamping sleeve, the support plate is evenly circumferentially provided with fan-shaped grooves consistent with the number of core wires, and the fan-shaped grooves and the sliding rod are spaced apart; the inner side surface of the clamping sleeve is an inclined structure inclined toward the center axis along the direction toward the support plate.

[0008] As a preferred technical solution of the present invention, the secondary connecting assembly includes a connecting sleeve, protrusions evenly arranged on the outer circumferential surface of the clamping sleeve, and grooves evenly opened on the inner circumferential surface of the connecting sleeve. The number of the protrusions and grooves is equal and they are used in conjunction with each other.

[0009] As a preferred technical solution of the present invention, a clamping piece is also provided on the side where the two support plates are connected to each other; the clamping piece includes a rubber ball arranged on one support plate and a spherical groove opened on the other support plate and cooperating with the rubber ball; the center of the rubber ball and the center of the spherical groove are both located on the outside of the support plate.

[0010] As a preferred technical solution of the present invention, the groove is divided into three sections: left, middle and right. The distance between the two side surfaces of the middle section remains unchanged, and the distance between the two side surfaces of the two side sections gradually increases along the moving direction of the secondary connecting component. The distance between the two sides of the connection between the left section and the right end and the middle section is equal to the distance between the two sides of the middle section. The protrusions on the two primary connecting components have the same shape and different sizes, and are respectively engaged with the left section and the right section of the groove.

[0011] As a preferred technical solution of the present invention, deformable rubber blocks are symmetrically arranged on the two side walls of the fan-shaped groove of the support plate, and the core wires are blocked and limited by the rubber blocks to prevent the core wire position from changing after the insulating tape is damaged, resulting in direct contact between different core wires; the opposite ends of the two rubber blocks are semicircular structures.

[0012] The present invention has the following beneficial effects: 1. An environmentally friendly cable of the present invention realizes two-level connection and fixation of two cables to be connected by means of a primary connection component and a secondary connection component, thereby increasing the strength of the connection and ensuring the stability of the connection.

[0013] 2. The primary connection assembly of the present invention separates multiple core wires at the cable connection through the support plate and the fan-shaped grooves uniformly arranged on it, increases the distance between the core wires, avoids direct contact, greatly reduces mutual interference between signals, improves the quality of signal transmission, and ensures the normal operation of the system; the core wire is limited by the rubber stopper to avoid direct contact between the core wire and other core wires after the insulating tape is damaged.

[0014] 3. The primary connection assembly of the present invention sets the inner circular surface of the clamping sleeve as an inclined structure, so that the clamping sleeve is gradually pressed against the outer sheath of the cable during its movement. On the one hand, the connection strength between the primary connection assembly and the cable is ensured, and on the other hand, the cable with the core wire twisted into a twist shape is fixed to avoid reset affecting the tightness of the core wire.

[0015] 4. The first-level connecting assembly of the present invention realizes the clamping connection of the two support plates through the clamping parts to avoid the problem that after the two support plates are connected, but the two clamping sleeves are not fixedly connected by the second-level connecting assembly, the cable 1 and the cable 2 have been rotated to a certain angle relative to each other, causing the clamping sleeve to damage the outer sheath of the cable due to resetting.

[0016] 5. The secondary connection assembly of the present invention avoids the circumferential and axial movement of the connection sleeve by the mutual cooperation between the protrusion and the groove, thereby realizing the stable connection of the two primary connection assemblies.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] See also Figure 1-Figure 2An environmentally friendly cable includes a cable 1, a cable 2 and a connecting mechanism 3 connected between the cable 1 and the cable 2; the cables connected by the connecting mechanism 3 can not only ensure the stability of the connection between the cables, but also ensure that a certain distance is maintained between the core wires 4 at the cable connection, reduce mutual interference between signals, improve the quality of signal transmission, and ensure the normal operation of the system.

[0026] See also Figure 2 The connecting mechanism 3 includes two primary connecting components 31 respectively sleeved on the cable 1 and the cable 2 and a secondary connecting component 32 jointly sleeved on the cable 1 and the cable 2; in specific operation, before the cable 1 and the cable 2 are connected, the secondary connecting component 32 is first sleeved on the cable 1 or the cable 2, and then the two primary connecting components 31 are respectively sleeved on the cable 1 and the cable 2, and then the multiple core wires 4 on the cable 1 and the cable 2 are peeled and tightened according to the corresponding colors, and the insulating tape is wrapped around the connection to make the cable 1 and the cable 2 connected. Then, rotate one of the primary connection components 31 and the corresponding cable. Since cable 1 and cable 2 are in a connected state at this time, the rotation of one of the cables causes the core wire 4 to be twisted into a twisted structure, further increasing the connection strength between cable 1 and cable 2; dock the two primary connection components 31 with each other and clamp them on the outer sheaths of the corresponding cables 1 and 2, so as to avoid rotation between cable 1 and cable 2, which may cause looseness and affect the connection strength; finally, move the secondary connection component 32 to connect the two primary connection components 31, thereby completing the cable connection.

[0027] See also Figure 3The primary connection assembly 31 includes a clamping sleeve 311, a support plate 312, and a slide bar 313 connected between the clamping sleeve 311 and the support plate 312. The slide bar 313 is slidably connected in the clamping sleeve 311, and the support plate 312 can slide axially relative to the clamping sleeve 311 through the slide bar 313; the support plate 312 is evenly provided with fan-shaped grooves in the circumference that are the same as the number of core wires 4, and the fan-shaped grooves and the slide bar 313 are spaced apart. When the primary connection assembly 31 is sleeved on the cable, the clamping sleeve 311 is located on the outer sheath of the corresponding cable 1 and cable 2, and the two support plates 31 2 is used to connect the core wires 4, and the core wires 4 are placed in each fan-shaped groove in turn. When the two primary connection components 31 are connected, the two support plates 312 are just located at the connection between the core wires 4 of the cable 1 1 and the cable 2 2, so that the core wires 4 of the corresponding colors on the cable 1 1 and the cable 2 2 are connected and tightened, and the core wires 4 of different colors are separated from each other without direct contact to cause signal interference. At the same time, when the cable 1 1 or the cable 2 2 is rotated by a certain angle and the core wires 4 are twisted into a twist shape, the tightness between the core wires 4 will also increase, and the support plates 312 can also prevent the core wires 4 from being too closely contacted to cause signal interference.

[0028] See also Figure 2 and Figure 5 , deformable rubber blocks 3123 are symmetrically arranged on the two side walls of the fan-shaped groove of the support plate 312, and the core wire 4 is blocked and limited by the rubber blocks to prevent the position of the core wire 4 from changing after the insulating tape is damaged, resulting in direct contact between different core wires 4; the opposite ends of the two rubber blocks 3123 are arc-shaped structures, which facilitates the insertion of the core wire 4.

[0029] See also Figure 2 and Figure 3 The diameter of the inner side surface of the clamping sleeve 311 gradually decreases from the direction close to the support plate 321 to the direction away from the support plate 312. When the two support plates 312 are connected, the two clamping sleeves 311 are pulled to move away from each other. The clamping sleeve 311 is gradually pressed against the outer sheath of the cable through the inclined surface structure. On the one hand, the connection strength between the primary connecting component 31 and the cable is ensured. On the other hand, the cable with the core wire 4 twisted into a twist shape is fixed to prevent the core wire 4 from rotating and resetting to affect the tightness of the core wire 4.

[0030] The inner side of the clamping sleeve 311 is made of rubber material, which increases the friction between the outer sheath of the cable and avoids damage to the outer sheath of the cable during movement; the support plate 312 is made of existing electromagnetic shielding material and is used to reduce electromagnetic interference between different signals between the core wires 4.

[0031] See also Figure 4The secondary connection component 32 includes a connection sleeve 321, protrusions 322 uniformly arranged on the outer circumferential surface of the clamping sleeve 311, and grooves 323 uniformly opened on the inner circumferential surface of the connection sleeve 321. The number of the protrusions 322 and the grooves 323 are equal and they are used in conjunction with each other. After the two primary connection components 31 are docked with each other and clamped on the corresponding outer sheaths of the cable 1 and the cable 2, the secondary connection component 32 is moved to the connection between the cable 1 and the cable 2. During the movement, the groove 323 is aligned with the protrusion 322, so that the connection sleeve 321 connects the two clamping sleeves 311 to each other and prevents them from rotating relative to each other, thereby ensuring the stability of the connection.

[0032] See also Figure 3 and Figure 4 The groove 323 is divided into three sections: left, middle and right. The distance between the two side surfaces of the middle section remains unchanged, and the distance between the two side surfaces of the two side sections gradually increases along the moving direction of the secondary connecting component 32, and the distance between the two sides of the connection between the left section and the middle section and the distance between the two sides of the connection between the right end and the middle section are equal to the distance between the two inclined surfaces of the middle section; the protrusions 322 on the two primary connecting components 31 have the same shape and different sizes, and are respectively engaged with the left and right sections of the groove 323. By setting the groove 323 to the above-mentioned structure, the secondary connecting component 32 can be smoothly moved and sleeved on the two clamping sleeves 311. At the same time, as the secondary connecting component 32 moves, the pressure between the groove 323 and the protrusion 322 can be gradually increased to improve the stability of the connection.

[0033] After the two support plates 312 are butted, the two clamping sleeves 311 are pulled away from each other, and the clamping sleeves 311 are gradually pressed against the outer sheath of the cable through the inclined surface structure. Although the cable twisted into a twisted shape of the core wire 4 can be fixed to a certain extent to avoid the impact of reset on the tightness of the core wire 4, the restoring force of the core wire 4 can easily cause the clamping sleeve 311 to cause external damage to the outer sheath of the cable. In order to avoid this situation, the present invention further provides a clamping member on the side where the two support plates 312 are butted against each other; Figure 5As shown, the clamping member includes a rubber ball 3121 arranged on a support plate 312 and a spherical groove 3122 opened on the other support plate 312 and cooperating with the rubber ball 3121; the center of the rubber ball 3121 is located on the outside of the support plate 312, and the center of the spherical groove 3122 is located inside the support plate 312. This arrangement can ensure the stability of the connection between the two support plates 312 and avoid the two from being separated. The clamping member can greatly avoid the problem that after the two support plates 312 are docked, but the secondary connection assembly 32 has not yet fixedly connected the two clamping sleeves 311, the cable 1 and the cable 2 that have been rotated relative to each other by a certain angle cause damage to the cable outer sheath due to the resetting of the clamping sleeve 311.
