Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a cable and wire connector. Background Art

[0002] In the field of power transmission and signal communication, cable and wire connectors are key components for line connection and signal transmission. Their performance is directly related to the stability and reliability of the entire system. With the continuous improvement of various industries' requirements for power supply and signal transmission, especially in heavy machinery and equipment, large-scale construction equipment, power systems, chemical production and other occasions with extremely high requirements for safety and stability, more stringent standards have been put forward for cable and wire connectors in terms of connection strength, resistance to external interference and long-term reliability.

[0003] Currently, there are many traditional cable and wire connectors on the market. Most of these connectors use a single snap-fit ​​connection method to achieve the fixation of the female connector and the male connector. Specifically, the mechanical connection is usually formed under the elastic force of the elastic block and the corresponding slot. Although this single snap-fit ​​connection method can achieve the fixation of the connector to a certain extent, it has exposed many defects in actual application:

[0004] On the one hand, the stability of a single snap-on connection is insufficient. When faced with complex working conditions such as external pulling, vibration, and torsional forces, this connection method is very likely to loosen or even disengage. For example, during the operation of heavy machinery, the strong vibration and impact force generated by the equipment will greatly affect the connector of the single snap-on connection, causing the cable and wire connection to loosen or disconnect easily, thereby affecting the normal operation of the equipment and even causing safety accidents. Moreover, under long-term vibration conditions, a single snap-on connection will gradually loosen due to vibration, and will not be able to effectively offset the displacement caused by vibration, which will increase the relative movement between the connectors, resulting in poor stability of the cable and wire connection, and problems such as signal interruption or power transmission failure.

[0005] On the other hand, traditional connectors pose greater risks when disassembling. Due to the use of a single snap-fit ​​structure, disassembly often requires direct forced pulling or prying. This operation method can easily damage the internal components of the connector, destroy the structural integrity of the connector, and increase maintenance costs. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a cable and wire connector that solves the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a cable and wire connector, comprising a male connector and a female connector, the male connector and the female connector are plugged together, and a connecting component is provided on the side of the female connector close to the male connector;

[0008] A docking groove is provided on the side of the female connector close to the male connector, a clamping ring is fixedly connected to the inner wall of the docking groove, and second clamping grooves are provided at both ends of the end face of the female connector;

[0009] The connecting assembly includes a fixed ring fixedly installed on the outer wall of the male connector, a rotating ring is threadedly connected to the outer wall of the fixed ring, rectangular grooves are provided at the upper and lower ends of the fixed ring, an L-shaped moving rod is slidably connected in the rectangular groove, and one end of the L-shaped moving rod is rotatably connected to the rotating ring, and elastic blocks are fixedly connected at both ends of the fixed ring close to the female connector, and the elastic block and the second slot are adapted to each other.

[0010] As a further optimization of the present technical solution, a trapezoidal plate is fixedly connected to the surface of the L-shaped movable rod, a bottom of the elastic block is fixedly connected to a base plate, and the bottom of the base plate is slidably connected to the surface of the trapezoidal plate.

[0011] As a further optimization of the present technical solution, an annular groove is provided on the outer surface of the rotating ring, and an installation groove is provided in a circular array on the rotating ring. A movable ring is threadedly connected in the annular groove, an arc block is fixedly connected to the inner wall of the movable ring in a circular array, and a sliding rod is slidably connected in the installation groove.

[0012] As a further optimization of this technical solution, the inner end of the sliding rod is fixedly connected to a clamping block, the outer end of the sliding rod slides in contact with the inner wall of the arc block, the outer wall of the sliding rod is fixedly connected to a limiting block, and a clamping block is provided on the inner side of the limiting block and is sleeved on the sliding rod.

[0013] As a further optimization of the present technical solution, movable grooves are provided on the upper and lower ends of the male connector, an elastic plate is provided on the inner wall of the movable groove, a protrusion is fixedly connected to the outer wall of the elastic plate, a first clamping groove which is adapted to the clamping ring is provided on the surface of the protrusion, the elastic plate is elastically installed in the first clamping groove, and the elastic plate moves toward the outside of the male connector under its own elastic force.

[0014] As a further preferred embodiment of the present technical solution, rounded corners are provided on both sides of the inner wall of the clamping ring to slide with the protrusion, and the protrusion is inclined on both sides.

[0015] As a further preferred embodiment of the present technical solution, one end of the L-shaped movable rod is fixedly connected to a cylinder, and the cylinder is slidably adapted to the protrusion.

[0016] Compared with the existing technology, it has the following beneficial effects:

[0017] Through the locking design of the elastic card block and the second card slot, when connecting the female connector and the male connector, the elastic card block is tightly combined with the second card slot under its own elastic force to form a reliable mechanical connection. This locking method can effectively prevent the connector from being easily detached when subjected to external forces such as pulling and vibration, thereby ensuring the stability of the cable and wire connection and the continuity of power or signal transmission; the trapezoidal plate pushes the bottom plate and the elastic card block to move to achieve the disengagement design, avoiding damage to the internal components of the connector due to direct forced disassembly. Compared with the traditional direct pulling or prying method, this gradual disengagement method is gentler, can effectively protect the structural integrity of the connector, and reduce maintenance costs.

[0018] On the basis of realizing the first connection by engaging the elastic card block with the second card slot, the clamping block is added to clamp the outer wall of the female connector to form a second connection fixation, forming a double connection mechanism. This double fixation method greatly improves the stability of the connection between the connectors and can effectively resist greater external pulling, vibration and torsional forces. For example, in heavy machinery and equipment, strong vibration and impact forces will be generated during the operation of the equipment. The double connection fixation can ensure that the cable and wire connections will not be easily loosened or disconnected, ensuring the normal operation of the equipment. The clamping block clamps the outer wall of the female connector so that the connector can be evenly supported in all directions. Uniform clamping force. Compared with single-point fixation or local fixation, the uniform force distribution can avoid deformation or damage of the connector due to excessive local force, further enhancing the reliability and stability of the connection; a single snap connection may gradually loosen due to long-term vibration, and the clamping effect of the clamping block can effectively offset the displacement caused by vibration and reduce the relative movement between the connectors, thereby ensuring the stability of the cable and wire connection and avoiding signal interruption or power transmission failure caused by vibration. When the connector is subjected to torsional force, the clamping of the clamping block can limit the relative rotation between the female connector and the male connector, preventing the connector from The internal structure may be damaged or the connection may fail due to torsion; in the process of rotating the movable ring to drive the clamping block to clamp the female connector, the contact between the clamping block and the outer wall of the female connector can play a certain positioning and correction role, which can ensure that the female connector and the male connector maintain precise alignment when connected, reducing poor contact or signal interference problems caused by connection deviation. The clamping force of the clamping block can prevent the female connector from being dislocated or offset during the connection process, ensuring that the electrical and mechanical connections between the connectors are accurate, and even in the case of external force interference, the correct position of the connector can be maintained, thereby improving the quality and Reliability; The double connection fixing mechanism greatly reduces the risk of accidental disconnection of the connector and improves the safety of cable and wire connections. In some occasions with extremely high safety requirements, such as power systems and chemical production, avoiding disconnection can prevent safety accidents such as short circuits, leakages, and fires, and ensure the safety of personnel and equipment. The damping spring is compressed during the clamping process, which can provide a certain buffering and shock absorption effect, reducing the damage to the connector caused by external force impact. At the same time, the elastic characteristics of the damping spring can ensure that the clamping block always maintains a certain clamping force during long-term use, ensuring the long-term stability and reliability of the connection.

[0019] By adding a clamping ring and a protrusion that engage in the first slot to form a third connection fixation on the basis of the first connection achieved by the elastic clamping block and the second slot, and the second connection achieved by clamping the clamping block, a triple connection guarantee system is constructed. This multiple fixing method greatly enhances the stability of the connection between the connectors and can withstand more complex and extreme external forces, such as strong pulling, torsion and vibration. For example, in the electrical connections of large-scale construction equipment, huge vibration and impact force will be generated during the operation of the equipment. The triple connection fixation can ensure that the cable and wire connections always remain stable, avoiding equipment failures and safety accidents caused by loose connections. Even if one or two of the connection methods show signs of loosening due to special circumstances, the other connection methods can still play a role, effectively preventing the connector from accidentally disengaging. This provides a strong guarantee for the reliability of the cable and wire connections and reduces the risk of system failures caused by connection failure. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Combination Figures 1-8 As shown, the present invention provides a technical solution: a cable and wire connector, which consists of two main parts, namely a male connector 1 and a female connector 2. The two connectors are designed to be plugged together to achieve the connection of cables and wires. In particular, the female connector 2 is provided with a connecting component 3 on a side close to the male connector 1 to enhance the stability and reliability of the connection;

[0031] To further enhance the stability of the connection, the female connector 2 is provided with a docking groove 21 on one side close to the male connector 1. A snap ring 22 is fixedly connected to the inner wall of the docking groove 21 to provide an additional fixing point during the connection process. In addition, second snap rings 23 are provided at both ends of the end face of the female connector 2. These snap rings provide a snap-in position for the elastic snap rings 37 in the connection assembly 3.

[0032] The design of the connecting assembly 3 also embodies innovation. It includes a fixed ring 31 fixedly mounted on the outer wall of the male connector 1. A rotating ring 32 is threadedly connected to the outer wall of the fixed ring 31, so that the rotating ring 32 can rotate on the fixed ring 31. In order to achieve more flexible movement, rectangular grooves 33 are formed at the upper and lower ends of the fixed ring 31. An L-shaped moving rod 34 is slidably connected in the rectangular groove 33. One end of the L-shaped moving rod 34 is rotatably connected to the rotating ring 32, so that the rotation of the rotating ring 32 can drive the movement of the L-shaped moving rod 34.

[0033] In order to ensure the stability of the connecting component 3 during the connection process, elastic blocks 37 are fixedly connected to the two ends of the fixing ring 31 close to the female connector 2. These elastic blocks 37 and the second card slots 23 of the female connector 2 can perfectly adapt to each other, thereby providing a stable engagement during connection. The surface of the L-shaped moving rod 34 is fixedly connected to the trapezoidal plate 36, and the bottom of the elastic block 37 is fixedly connected to the bottom plate 38. The bottom of the bottom plate 38 is slidably connected to the surface of the trapezoidal plate 36. In this way, under the elastic force of the elastic block 37 itself, the bottom plate 38 can be driven to move toward one side of the L-shaped moving rod 34.

[0034] When the female connector 2 is connected to the male connector 1, the elastic block 37 is first inserted into the second slot 23, and then the rotating ring 32 is rotated to move it to the right, so that the rotating ring 32 will drive the L-shaped moving rod 34, the cylinder 35, and the trapezoidal plate 36 to move to the right together. When the bottom plate 38 moves to a point where it is no longer in contact with the trapezoidal plate 36, the elastic block 37 continues to drive the bottom plate 38 to move to one side of the L-shaped moving rod 34 under the drive of its own elastic force. Finally, the elastic block 37 forms a firm engagement with the second slot 23 of the female connector 2, ensuring the connection strength and reliability of the cable and wire connector.

[0035] In an embodiment of the present invention, Figure 2 As shown, when performing the connection operation between the female connector 2 and the male connector 1, it is first necessary to insert the elastic block 37 into the second slot 23. Then, by rotating the rotating ring 32, it moves to the right, thereby driving the L-shaped moving rod 34, the cylinder 35 and the trapezoidal plate 36 to move to the right together. When the bottom plate 38 moves to a position where it no longer contacts the trapezoidal plate 36, the elastic block 37 will use its own elastic force to push the bottom plate 38 to move in the direction of the L-shaped moving rod 34, and finally the elastic block 37 is tightly combined with the second slot 23 of the female connector 2. This design of the engagement between the elastic block 37 and the second slot 23 , not only provides a reliable mechanical connection when connecting the female connector 2 and the male connector 1, but also effectively prevents the connector from being easily disengaged when facing adverse factors such as external pulling and vibration, thereby ensuring the stability of the cable and wire connection and the continuity of power or signal transmission. The trapezoidal plate 36 realizes the disengagement design by pushing the bottom plate 38 and the elastic block 37 to move. This method avoids the damage that may be caused to the internal components of the connector by direct forced disassembly. Compared with the traditional direct pulling or prying method, this gradual disengagement method is more gentle and can effectively protect the structural integrity of the connector, thereby reducing maintenance costs;

[0036] When it is necessary to release the engagement between the elastic block 37 and the second slot 23, the operator should rotate the rotating ring 32 in the opposite direction to move it to the left. This action of the rotating ring 32 will drive the L-shaped moving rod 34, the cylinder 35 and the trapezoidal plate 36 to move to the left together. Then, the trapezoidal plate 36 will push the bottom plate 38 and the elastic block 37 to move away from the L-shaped moving rod 34 until the elastic block 37 no longer forms an engagement with the second slot 23. At this time, the operator can easily separate the female connector 2 from the male connector 1, completing the entire disconnection process.

[0037] Example 2: Combination Figure 3 、 Figure 4 As shown, based on the first embodiment, an annular groove 39 is carefully designed and processed on the outer surface of the rotating ring 32. The annular groove 39 is evenly distributed along the circumference of the rotating ring 32 to form a continuous groove structure. A movable ring 310 is installed inside the annular groove 39 by means of a threaded connection. The inner wall of the movable ring 310 is also arranged in an array in the circumferential direction and fixedly connected to a plurality of arc blocks 312.

[0038] The rotating ring 32 is further provided with a series of mounting grooves 311, which are evenly distributed along the circumference of the rotating ring 32. A sliding rod 313 is slidably connected to each mounting groove 311. The design of the sliding rod 313 allows it to move freely within the mounting groove 311 to adapt to different working conditions.

[0039] The inner end of the sliding rod 313 is fixedly connected to the clamping block 315. The clamping block 315 can be any structure suitable for clamping or fixing an object. The outer end of the sliding rod 313 slides in contact with the inner wall of the arc block 312. This design ensures the stability of the sliding rod 313 during movement. In order to further limit the range of movement of the sliding rod 313, a limiting block 314 is fixedly connected to its outer wall. The inner side of the limiting block 314 is provided with a clamping block 315 that is sleeved on the sliding rod 313. In this way, when the sliding rod 313 moves to a predetermined position, the limiting block 314 can ensure that the clamping block 315 is accurately positioned at the desired position, thereby achieving precise clamping or fixing function.

[0040] In the embodiment of the present invention, after the elastic block 37 is engaged with the second slot 23 of the female connector 2, the arc block 312 is driven to rotate synchronously by rotating the movable ring 310, so that the arc block 312 pushes the sliding rod 313, the limit block 314, and the clamping block 315 to move inward during rotation, and compresses the damping spring 316, so that the clamping block 315 clamps the outer wall of the female connector 2, thereby achieving a second connection and fixation between the female connector 2 and the male connector 1; this connection method not only ensures the stability of the connection, but also provides a more reliable connection effect when facing external pulling, vibration and torsional force. For example, in heavy machinery and equipment, strong vibration and impact force will be generated during equipment operation. The double connection and fixation can ensure that the cable and wire connection will not be easily loosened or disconnected, thereby ensuring the normal operation of the equipment;

[0041] The clamping block 315 clamps the outer wall of the female connector 2, so that the connector is subjected to uniform clamping force in all directions. Compared with single-point fixation or local fixation, the uniform force distribution can prevent the connector from being deformed or damaged due to excessive local force, further enhancing the reliability and stability of the connection. A single snap connection may gradually loosen due to long-term vibration, but the clamping effect of the clamping block 315 can effectively offset the displacement caused by vibration and reduce the relative movement between the connectors, thereby ensuring the stability of the cable and wire connection and avoiding signal interruption or power transmission failure caused by vibration.

[0042] When the connector is subjected to a torsional force, the clamping of the clamping block 315 can limit the relative rotation between the female connector 2 and the male connector 1, preventing the internal structure of the connector from being damaged or causing connection failure due to torsion. In the process of rotating the movable ring 310 to drive the clamping block 315 to clamp the female connector 2, the contact between the clamping block 315 and the outer wall of the female connector 2 can play a certain positioning and correction role, which can ensure that the female connector 2 and the male connector 1 maintain precise alignment during connection, reducing poor contact or signal interference problems caused by connection deviation;

[0043] The clamping force of the clamping block 315 can prevent the female connector 2 from being misplaced or offset during the connection process, ensuring that the electrical and mechanical connections between the connectors are accurate. Even when disturbed by external forces, the correct position of the connector can be maintained, thereby improving the quality and reliability of the connection. The dual connection fixing mechanism greatly reduces the risk of accidental disconnection of the connector and improves the safety of the cable and wire connection. In some situations with extremely high safety requirements, such as power systems and chemical production, avoiding disconnection can prevent safety accidents such as short circuits, leakages, and fires, thereby ensuring the safety of personnel and equipment.

[0044] The damping spring 316 is compressed during the clamping process, which can provide a certain buffering and shock absorption effect, reducing the damage to the connector caused by external force impact. At the same time, the elastic characteristics of the damping spring 316 can ensure that the clamping block 315 always maintains a certain clamping force during long-term use, ensuring the long-term stability and reliability of the connection.

[0045] Example 3: Combination Figure 6 、 Figure 7 、 Figure 8 As shown, based on the second embodiment, movable grooves 11 are designed at the upper and lower ends of the male connector 1. The inner walls of these movable grooves 11 are carefully configured with elastic plates 12. The outer walls of these elastic plates 12 are tightly connected to the protrusions 13 by a fixed connection. In order to ensure that the protrusions 13 and the snap rings 22 can perfectly match, we carefully designed a first clamping groove 14 on the surface of the protrusion 13 that is adapted to the snap ring 22. The elastic plate 12 is cleverly and elastically installed in the first clamping groove 14. By utilizing its own elastic force, it can effectively move toward the outside of the male connector 1, thereby achieving a specific function.

[0046] The inner wall of the snap ring 22 is specially designed with rounded corners on both sides to slide with the protrusion 13. This design is not only beautiful but also ensures smooth movement of the protrusion 13. At the same time, the two sides of the protrusion 13 are tilted. This structural design allows the protrusion 13 to provide a larger contact area and better stability when mating with the snap ring 22.

[0047] One end of the L-shaped moving rod 34 is fixedly connected to a cylinder 35, and a sliding adaptation structure is designed between the cylinder 35 and the protrusion 13. This design not only ensures smooth sliding between the L-shaped moving rod 34 and the protrusion 13, but also in actual application, can effectively transmit the force and ensure the stable operation of the entire mechanical device.

[0048] When the female connector 2 is connected to the male connector 1, that is, the female connector 2 moves toward the male connector 1, the snap ring 22 and the protrusion 13 begin to contact. Since the snap ring 22 is designed with a smooth edge and the two sides of the protrusion 13 are inclined, this design enables the snap ring 22 to effectively push the protrusion 13 and the elastic plate 12 to move toward the inner side of the male connector 1. As the snap ring 22 moves further, it will eventually engage with the first engaging groove 14. At the same time, the elastic engaging block 37 will also engage with the second engaging groove 23. When the snap ring 22 reaches the predetermined position of the first engaging groove 14, the protrusion 13 and the elastic plate 12 will move toward the outside of the male connector 1 under the action of their own elastic force, so that the first engaging groove 14 of the protrusion 13 is tightly engaged with the snap ring 22, thereby realizing the third connection and fixation of the female connector 2 and the male connector 1. Through this design, we have constructed a triple connection guarantee system: first, the elastic The engagement of the locking block 37 with the second slot 23 realizes the first connection; secondly, the clamping of the clamping block 315 realizes the second connection; finally, the engagement of the clamping ring 22 with the protrusion 13 in the first slot 14 forms the third connection fixation. This multiple fixing method greatly enhances the stability of the connection between the connectors and can withstand more complex and extreme external forces, such as strong pulling, torsion and vibration. In the electrical connection of large-scale construction equipment, huge vibration and impact force will be generated during the operation of the equipment. The triple connection fixation can ensure that the cable and wire connection always remains stable, avoiding equipment failure and safety accidents caused by loose connection. Even if one or two of the connection methods show signs of loosening due to special circumstances, such as excessive instantaneous external force impact, the other connection methods can still play a role, effectively preventing the connector from accidentally disengaging, which provides a strong guarantee for the reliability of the cable and wire connection and reduces the risk of system failure caused by connection failure.

[0049] When the female connector 2 is in contact with the male connector 1 and is ready to be connected, the rotating ring 32 will drive the L-shaped moving rod 34 and the cylinder 35 to move toward the female connector 2. This action enables the cylinder 35 to push the protrusion 13 and the elastic plate 12 to move inward, thereby releasing the engagement between the protrusion 13 and the retaining ring 22. When the protrusion 13 no longer forms an engagement with the retaining ring 22, the connection between the female connector 2 and the male connector 1 is released. This design allows the user to easily disconnect when needed while ensuring the convenience and safety of the connection process.

[0050] Working principle of cable and wire connectors:

[0051] Step 1: When the female connector 2 is connected to the male connector 1, the elastic block 37 is inserted into the second slot 23, and then the rotating ring 32 is rotated to move it to the right, so that the rotating ring 32 drives the L-shaped moving rod 34, the cylinder 35, and the trapezoidal plate 36 to move to the right. When the bottom plate 38 moves to a point where it is no longer in contact with the trapezoidal plate 36, the elastic block 37 drives the bottom plate 38 to move toward the side of the L-shaped moving rod 34 under its own elastic force, so that the elastic block 37 is engaged with the second slot 23 of the female connector 2;

[0052] Step 2: When the female connector 2 is connected to the male connector 1, that is, when the female connector 2 moves toward the side of the male connector 1, the snap ring 22 contacts the protrusion 13. Since the snap ring 22 is provided with rounded corners and the protrusion 13 is inclined at both sides, the snap ring 22 can push the protrusion 13 and the elastic plate 12 to move toward the inside of the male connector 1, so that the snap ring 22 moves and engages in the first engaging groove 14. After the elastic engaging block 37 is engaged in the second engaging groove 23, the snap ring 22 is just located at the position of the first engaging groove 14. Then, the protrusion 13 and the elastic plate 12 move toward the outside of the male connector 1 under their own elastic force, so that the first engaging groove 14 of the protrusion 13 is engaged and fixed with the snap ring 22.

[0053] Step 3. After the elastic block 37 is engaged with the second slot 23 of the female connector 2, the arc block 312 is driven to rotate synchronously by rotating the movable ring 310, so that the arc block 312 pushes the sliding rod 313, the limit block 314, and the clamping block 315 to move inward during rotation, and compresses the damping spring 316, so that the clamping block 315 clamps the outer wall of the female connector 2, thereby enabling the female connector 2 and the male connector 1 to be connected and fixed for the second time.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
