Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, specifically to a cable connector. Background Technology

[0002] Cable connectors are mainly used for signal transmission between various digital program-controlled exchanges, optoelectronic transmission equipment, and patch panels in transmission equipment, for transmitting data, audio, video, and other communication devices. In electronic product assembly, cable connectors are widely used; they are key products for ensuring the correctness and reliability of electrical signal transmission. There are many types of cable connectors, mainly divided into low-frequency and high-frequency, and circular and rectangular types.

[0003] In the existing technology, cable connectors are connected by threads or snap-fit. When the connector is subjected to external vibration, cable pulling or mechanical impact, the threads are prone to loosening and the snap-fit ​​structure may accidentally unlock due to loss of elasticity or insufficient engagement depth, resulting in connection interruption or even equipment failure. Utility Model Content

[0004] The purpose of this invention is to provide a cable connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable connector, including a connecting end and a connecting seat, wherein the connecting seat is correspondingly arranged with the connecting end, and both the connecting end and the connecting seat are provided in two sets. A base is provided below the connecting seat, and two sets of cross-distributed brackets are provided between the connecting seat and the base. The upper ends of both sets of brackets are rotatably connected to the connecting seat, and a slider is rotatably installed at the lower end of the bracket. A damping rod is fixedly installed between the slider and the base, and a second spring is sleeved on the damping rod. A connecting rod is provided between the two sets of connecting seats, and two sets of symmetrically distributed first adjusting rods are slidably installed inside the connecting rod. A second adjusting rod is slidably installed inside each of the two sets of first adjusting rods, and the two sets of second adjusting rods are respectively fixedly connected to the corresponding connecting seats.

[0006] As a further preferred embodiment of this technical solution, a sliding rod is fixedly installed inside the base, the slider is slidably sleeved with the sliding rod, and two sets of symmetrically distributed first springs are sleeved on the sliding rod, with the two ends of the two sets of first springs respectively fixedly connected to the slider and the base.

[0007] As a further preferred embodiment of this technical solution, a bidirectional screw is rotatably installed inside the connecting rod. The two ends of the bidirectional screw pass through two sets of first adjusting rods and are threadedly connected to the two sets of first adjusting rods respectively. A screw tube is rotatably installed inside each set of first adjusting rods. The screw tube passes through the corresponding second adjusting rod and is threadedly connected to the second adjusting rod respectively.

[0008] As a further preferred embodiment of this technical solution, the bidirectional screw is provided with two sets of symmetrically distributed slots, and the spiral tube is provided with two sets of symmetrically distributed blocks. The blocks are arranged correspondingly to the slots, and the spiral tube is slidably connected to the bidirectional screw through the blocks.

[0009] As a further preferred embodiment of this technical solution, an installation ring is rotatably installed inside the connecting seat, and multiple sets of annularly distributed positioning plates are rotatably installed inside the connecting seat. The connecting end is provided with a positioning groove, and the multiple sets of positioning plates are movably engaged with the connecting end through the positioning groove.

[0010] As a further preferred embodiment of this technical solution, multiple sets of positioning plates are rotatably connected to the connecting seat via mounting shafts, multiple sets of mounting shafts are fitted with gears, and mounting rings are fitted with toothed rings, with multiple sets of gears meshing with the toothed rings.

[0011] This utility model provides a cable connector, which has the following advantages:

[0012] (1) This utility model forms a multi-level, multi-directional vibration damping and buffering system by rotating the cross-distributed brackets and connecting seats and base, in conjunction with the slider, damping rod (containing a second spring) and the first spring on the sliding rod inside the base. This structure can effectively absorb vibration energy and instantaneous impact force (such as pulling and collision) from different directions (especially axial and transverse), significantly reducing the degree of vibration and impact transmission to the joint of the connecting end and the connecting seat. It fundamentally solves the problem of thread loosening or accidental unlocking of the snap-fit ​​structure caused by vibration. The connecting seat adopts the design of installation ring drive (meshing with gear through toothed ring) and multiple sets of ring-distributed positioning plates working together to achieve multi-point, uniform, and circumferential locking of the connecting end, greatly increasing the redundancy and overall rigidity of the locking structure. Even if a single positioning point is subjected to abnormal stress, the other points can still provide effective holding force, effectively overcoming the risk of accidental unlocking caused by single-point failure or elastic fatigue and insufficient meshing depth of the traditional snap-fit ​​structure, ensuring the long-term stability of the connection under harsh working conditions.

[0013] (2) This utility model uses an adjustment mechanism composed of a connecting rod, a bidirectional screw, a first adjusting rod, a second adjusting rod, a screw tube, and a slot / block structure to allow flexible adjustment of the distance between two sets of connectors to adapt to the cable connection requirements of different specifications or installation positions. After adjustment, the adjustment mechanism provides a rigid support connection through the engagement of the thread and the cooperation of the slot and block, effectively connecting the two sets of connectors into an integral frame. This significantly enhances the overall rigidity and stability of the entire connector structure, preventing relative displacement or deformation of the connectors under force (such as lateral force or torque), thereby protecting the internal electrical connection points. During the rotation of the bidirectional screw, the two sets of first adjusting rods slide synchronously inward or outward in the connecting rod under the limiting action of the connecting rod. Under the action of the slot and block, the screw tube rotates synchronously with the bidirectional screw. Therefore, under the limiting action of the first adjusting rod, the two sets of second adjusting rods slide synchronously inward or outward, completing the adjustment of the distance between the two sets of connectors.

[0021] 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.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a cable connector includes a connecting end 1 and a connecting seat 2. The connecting seat 2 is correspondingly arranged to the connecting end 1. Both the connecting end 1 and the connecting seat 2 have two sets. A base 3 is provided below the connecting seat 2. Two sets of cross-distributed brackets 7 are provided between the connecting seat 2 and the base 3. The upper ends of both sets of brackets 7 are rotatably connected to the connecting seat 2. A slider 8 is rotatably mounted on the lower end of the bracket 7. A damping rod 11 is fixedly installed between the slider 8 and the base 3. A second spring 12 is sleeved on the damping rod 11. A connecting rod 4 is provided between the two sets of connecting seats 2. Two sets of symmetrically distributed first adjusting rods 5 are slidably installed in the connecting rod 4. A second adjusting rod 6 is slidably installed in each of the two sets of first adjusting rods 5. The two sets of second adjusting rods 6 are respectively fixedly connected to the corresponding connecting seat 2. A sliding rod 9 is fixedly installed in the base 3. The slider 8 is slidably sleeved with the sliding rod 9. Two sets of symmetrically distributed first springs 10 are sleeved on the sliding rod 9. The two ends of the two sets of first springs 10 are respectively fixedly connected to the slider 8 and the base 3. The cross-distributed brackets 7 connect the connecting seat 2 to the connecting seat 2. The rotating connection of the base 3, together with the slider 8, the damping rod 11 containing the second spring 12, and the first spring 10 on the slider 9 inside the base 3, constitutes a multi-stage, multi-directional vibration damping and buffering system. This structure can effectively absorb vibration energy and instantaneous impact forces such as pulling and collision from different directions, especially axial and lateral ones, significantly reducing the degree of vibration and impact transmission to the joint between the connecting end 1 and the connecting seat 2. It fundamentally solves the problem of thread loosening or accidental unlocking of the snap-fit ​​structure caused by vibration. The connecting seat 2 adopts a design in which the mounting ring 17 drives the gear ring 18 to mesh with the gear 21, and multiple sets of ring-distributed positioning plates 19 work together to achieve multi-point, uniform, and circumferential locking of the connecting end 1. This greatly increases the redundancy and overall rigidity of the locking structure. Even if a single positioning point is subjected to abnormal stress, the other points can still provide effective holding force. This effectively overcomes the risk of accidental unlocking caused by single-point failure or elastic fatigue and insufficient engagement depth of traditional snap-fit ​​structures, ensuring the long-term stability of the connection under harsh working conditions.

[0023] like Figure 4 , Figure 5 and Figure 6As shown, a bidirectional screw 13 is rotatably installed inside the connecting rod 4. Both ends of the bidirectional screw 13 pass through two sets of first adjusting rods 5 and are threadedly connected to the two sets of first adjusting rods 5 respectively. A screw tube 15 is rotatably installed inside each set of first adjusting rods 5, passing through the corresponding second adjusting rod 6 and being threadedly connected to the second adjusting rod 6. Two sets of symmetrically distributed slots 14 are provided on the bidirectional screw 13. Two sets of symmetrically distributed locking blocks 16 are provided inside the screw tube 15, with the locking blocks 16 corresponding to the slots 14. The screw tube 15 is slidably sleeved with the bidirectional screw 13 through the locking blocks 16. An installation ring 17 is rotatably installed inside the connecting seat 2. Multiple sets of annularly distributed positioning plates 19 are rotatably installed inside the connecting seat 2. A positioning groove 22 is provided at the connecting end 1. All 9 are movably engaged with the connecting end 1 via the positioning groove 22. Multiple sets of positioning plates 19 are rotatably connected to the connecting seat 2 via the mounting shaft 20. Gears 21 are sleeved on the multiple sets of mounting shafts 20. Gear rings 18 are sleeved on the mounting ring 17. Multiple sets of gears 21 are meshed with the gear rings 18. The adjustment mechanism, composed of the connecting rod 4, the bidirectional screw 13, the first adjusting rod 5, the second adjusting rod 6, the screw tube 15, and the slot 14 / block 16, allows for flexible adjustment of the distance between the two sets of connecting seats 2 to adapt to the cable connection requirements of different specifications or installation positions. After the adjustment is completed, the adjustment mechanism provides a rigid support connection through the thread engagement and the cooperation of the slot 14 and the block 16, effectively connecting the two sets of connecting seats 2 into an integral frame. This significantly enhances the overall rigidity and stability of the connector structure, preventing relative displacement or deformation of the connector 2 under stress such as lateral force or torque, thereby protecting the internal electrical connection points. During the rotation of the bidirectional screw 13, the two sets of first adjusting rods 5 slide synchronously inward or outward in the connecting rod 4 under the limiting action of the connecting rod 4. Under the action of the slot 14 and the locking block 16, the screw tube 15 rotates synchronously with the bidirectional screw 13. Therefore, under the limiting action of the first adjusting rod 5, the two sets of second adjusting rods 6 slide synchronously inward or outward, completing the adjustment of the distance between the two sets of connector 2.

[0024] This utility model provides a cable connector, the specific working principle of which is as follows: Through the rotatable connection of the cross-distributed brackets 7 with the connecting seat 2 and the base 3, and in conjunction with the slider 8, the damping rod 11 containing the second spring 12, and the first spring 10 on the slide rod 9 inside the base 3, a multi-stage, multi-directional vibration damping and buffering system is formed. This structure can effectively absorb vibration energy and instantaneous impact forces such as pulling and collision from different directions, especially axial and lateral, significantly reducing the degree of vibration and impact transmission to the joint between the connecting end 1 and the connecting seat 2. This fundamentally solves the problem of thread loosening or accidental unlocking of the snap-fit ​​structure caused by vibration. The connecting seat 2 employs a design where the mounting ring 17 drives the meshing of the gear ring 18 and gear 21, and multiple sets of annularly distributed positioning plates 19 work in concert, achieving multi-stage, multi-directional vibration damping and buffering of the connecting end 1. The point-based, uniform, and circumferential locking greatly increases the redundancy and overall rigidity of the locking structure. Even if a single positioning point is subjected to abnormal stress, the remaining points can still provide effective holding force, effectively overcoming the risk of accidental unlocking caused by single-point failure, elastic fatigue, or insufficient engagement depth in traditional snap-fit ​​structures. This ensures the long-term stability of the connection under harsh working conditions. The adjustment mechanism, composed of the connecting rod 4, bidirectional screw 13, first adjusting rod 5, second adjusting rod 6, screw tube 15, and slot 14 / block 16, allows for flexible adjustment of the distance between the two sets of connecting seats 2 to adapt to the cable connection requirements of different specifications or installation positions. After adjustment, the adjustment mechanism provides a rigid support connection through thread engagement and the cooperation of slot 14 and block 16, effectively connecting the two sets of connecting seats 2 into an integral frame. This significantly enhances the overall rigidity and stability of the connector structure, preventing relative displacement or deformation of the connector 2 under stress such as lateral force or torque, thereby protecting the internal electrical connection points. During the rotation of the bidirectional screw 13, the two sets of first adjusting rods 5 slide synchronously inward or outward in the connecting rod 4 under the limiting action of the connecting rod 4. Under the action of the slot 14 and the locking block 16, the screw tube 15 rotates synchronously with the bidirectional screw 13. Therefore, under the limiting action of the first adjusting rod 5, the two sets of second adjusting rods 6 slide synchronously inward or outward, completing the adjustment of the distance between the two sets of connector 2.
