Description

Technical Field

[0001] This utility model belongs to the field of connecting cable technology, specifically relating to a connecting cable with a built-in protective structure. Background Technology

[0002] Connecting cables are the "bridges" that transmit power or signals between devices and systems. They are made of conductive materials such as copper and aluminum, with an outer insulating layer to prevent leakage and interference. Some also have a shielding layer to reduce signal loss. They range from small mobile phone charging cables and computer data cables to large industrial equipment control cables and power grid transmission lines. They can adapt to different voltages and signal types to ensure the stable operation of various electronic devices and power systems.

[0003] Most existing connection cables use a plug-in method for connection, relying mainly on friction at the connection point for fixation. While this method can complete the basic connection, it has obvious shortcomings in actual use: on the one hand, the connection point lacks a protective structure, and external rainwater, dust, etc. can easily seep into the gaps, which may corrode the interface or cause short circuits, damaging the cable connection; on the other hand, relying solely on friction to maintain fixation makes it very easy to loosen when encountering external forces such as vibration or pulling, which can lead to poor contact and affect the stability of signal transmission or power supply.

The side surface of the connecting protrusion is provided with a plurality of positioning blocks arranged in a circular array. A rotating ring is sleeved on the side surface of the connector male. The end of the rotating ring away from the cable body is fixedly connected to a fixing plate arranged in a circular array, and a positioning groove is formed on the adjacent side of the fixing plates. The positioning groove is engaged with the positioning block. The inner wall of the connecting groove is provided with a support component to improve the connection strength between the connector male and the connector female.

[0006] In a preferred embodiment, the shape of the connecting protrusion is adapted to the shape of the connecting groove, and the shape of the positioning block and the positioning groove are "Z" shaped.

[0008] In a preferred embodiment, the inner wall of the side surface of the connector head is provided with a rotating groove, and a connecting ring is fixedly connected to the inner ring side surface of the rotating ring. The rotating ring is rotatably connected to the connector head through the connecting ring, and the connecting ring is rotatably sleeved inside the rotating groove. A plurality of damping strips are provided on the outer ring side surface of the rotating ring in a ring array.

[0009] In a preferred embodiment, the rotating ring, connecting ring, and fixing plate are integrally formed, and the end of the connecting male and female connectors near the cable body is tapered.

[0010] In a preferred embodiment, the connecting groove is provided with a line connector inside, and the support ring is sleeved on the outside of the line connector. The connecting protrusion is provided with a line connection hole adapted to the line connector inside.

[0014] The present invention will be further described below with reference to the embodiments.

[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figure 1-4 This utility model provides a connecting cable with a built-in protective structure, including a cable body 1. One end of the cable body 1 is provided with a connector 101, and the other end away from the connector 101 is provided with a connector 102. By connecting the connector 101 and the connector 102, the connection between the two cables can be effectively realized. The connector 101 has a connecting groove 2 inside, and the connector 102 has a connecting protrusion 3 at the end away from the cable body 1. The side surface of the connecting protrusion 3 has a plurality of fixed points arranged in a ring array. The side surface of the connector 101 is fitted with a rotating ring 7. The end of the rotating ring 7 away from the cable body 1 is fixedly connected to a fixed plate 8 arranged in a ring array. The rotating ring 7 and the fixed plate 8 cooperate to cover the connection between the connector 101 and the connector 102, thereby blocking the gap between them. A positioning groove 9 is formed on the adjacent side of the fixed plate 8. The positioning groove 9 is snapped into the positioning block 4. The inner wall of the connection groove 2 is provided with a support component to improve the connection strength between the connector 101 and the connector 102.

[0017] In this invention, when connecting cables, first align the connecting protrusion 3 on the female connector 102 with the connecting groove 2 of the male connector 101 and insert it. At this time, the positioning block 4 on the side surface of the connecting protrusion 3 initially corresponds to the positioning groove 9 formed by the fixing piece 8 on the rotating ring 7. Then, rotate the rotating ring 7 on the side surface of the male connector 101. Because the positioning block 4 and the positioning groove 9 have a "Z" shaped structure, during the rotation, the positioning block 4 will slide along the "Z" shaped trajectory of the positioning groove 9 and eventually lock in place, achieving the initial fixation of the male connector 101 and the female connector 102. This invention ensures the alignment accuracy during connection through the shape compatibility of the connecting protrusion 3 and the connecting groove 2, avoiding connection failure due to misalignment. The U-shaped positioning block 4, in conjunction with the positioning groove 9, effectively prevents the connector 101 and connector 102 from loosening axially or radially after connection, compared to a regular straight groove structure. This significantly improves the stability of the basic connection. Meanwhile, the combination of the rotating ring 7 and the fixing piece 8 makes installation more convenient, requiring no additional tools for fixing. Furthermore, the rotating ring 7 and the fixing piece 8 can also cover the gap between the connector 102 and connector 101, effectively preventing rainwater or dust from entering and damaging the circuit, thus ensuring the safety and stability of the cable connection.

[0018] Specifically, such as Figure 1 and Figure 3As shown, the shape of the connecting protrusion 3 matches that of the connecting groove 2. The shape compatibility of the connecting protrusion 3 and the connecting groove 2 ensures the alignment accuracy during connection and avoids connection failure due to misalignment. The positioning block 4 and the positioning groove 9 are in the shape of a "Z". The "Z" shaped positioning block 4 and the positioning groove 9 cooperate with each other. Compared with the ordinary straight groove structure, it can effectively prevent the connecting male head 101 and the connecting female head 102 from loosening along the axial or radial direction after connection, which significantly improves the stability of the basic connection. At the same time, the cooperation between the rotating ring 7 and the fixing piece 8 makes the installation operation more convenient and can be fixed without additional tools.

[0019] Specifically, such as Figure 3 and Figure 2 As shown, the support assembly includes a buffer cavity 12 formed in the inner wall of the connecting groove 2. The buffer cavity 12 provides guidance for the sliding of the support ring 11, preventing the support ring 11 from shifting and causing support failure. The support ring 11 is slidably connected inside the buffer cavity 12. A helical spring 13 is fixedly connected between the support ring 11 and the buffer cavity 12. The cooperation between the support ring 11 and the helical spring 13 can provide elastic support for the docking of the line connector and the line hole, effectively reducing contact problems caused by vibration and impact, and ensuring the stability of cable signal or current transmission.

[0020] Specifically, such as Figure 3 As shown, a rotating groove 5 is provided on the inner wall of the side surface of the connector 101. A connecting ring 6 is fixedly connected to the inner ring side surface of the rotating ring 7. The rotating ring 7 is rotatably connected to the connector 101 through the connecting ring 6. The matching structure of the connecting ring 6 and the rotating groove 5 not only ensures the smooth rotation of the rotating ring 7, but also prevents it from falling off axially, thus improving the installation stability of the rotating ring 7. The connecting ring 6 is rotatably sleeved inside the rotating groove 5. Several damping strips 10 are arranged in a ring array on the outer ring side surface of the rotating ring 7.

[0021] Specifically, such as Figure 3 As shown, the rotating ring 7, connecting ring 6, and fixing plate 8 are integrally molded structures. The integral molding structure reduces the splicing gaps of the parts, improves the overall structural strength of the rotating ring 7, connecting ring 6, and fixing plate 8, reduces the risk of parts breaking or separating after long-term use, and extends the service life of the cable. The ends of the connecting male head 101 and connecting female head 102 near the cable body 1 are tapered. The tapered transition structure effectively solves the problem that traditional straight-edge connectors are prone to breakage of the cable body 1 at the joint due to stress concentration, significantly improves the bending resistance of the cable, and extends its service life.

[0022] Specifically, such as Figure 3 and Figure 4As shown, the inside of the connecting groove 2 is provided with a line connector, and the support ring 11 is sleeved on the outside of the line connector. The inside of the connecting protrusion 3 is provided with a line connection hole adapted to the line connector. When the line connector is inserted into the line connection hole, the electrical connection between the two cables can be completed.

[0023] Working principle and usage process of this utility model: When performing cable connection operations, the staff first holds the cable body 1, holding the connector 101 at one end and the connector 102 at the other end. The staff aligns the connector protrusion 3 at the end of the connector 102 away from the cable body 1 with the connector groove 2 inside the connector 101 and slowly inserts it. During the insertion process, the positioning block 4 on the side surface of the connector protrusion 3 will initially correspond to the positioning groove 9 between the fixing piece 8 on the rotating ring 7. At the same time, the end of the connector protrusion 3 will push the support ring 11 that is slidably connected in the buffer cavity 12 inside the inner wall of the connector groove 2, causing the spiral spring 13 that is fixedly connected between the support ring 11 and the buffer cavity 12 to contract. Next, the staff pinches the damping strip 10 on the outer side surface of the rotating ring 7 and rotates the rotating ring 7. During the rotation, the "Z"-shaped positioning block 4 slides along the "Z"-shaped trajectory of the positioning groove 9 and finally locks in place, thus achieving a stable fixation between the connector 101 and the connector 102. At this time, the rotating ring 7 and the fixing plate 8 cooperate to cover the connection between the two, blocking the gap to prevent rainwater and dust from entering and damaging the circuit. At the same time, the helical spring 13 elastically returns to its original position, pushing the support ring 11 to press tightly against the connecting protrusion 3, providing elastic support for the docking of the line connector in the connecting groove 2 and the matching line hole inside the connecting protrusion 3, reducing poor contact caused by vibration and impact, and ensuring stable signal or current transmission.

[0024] 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.
