Description

Technical Field

[0001] This utility model relates to the field of power transmission connection technology, specifically to a cable connector with a wire insertion positioning recognition function. Background Technology

[0002] In power operations such as transmission line erection and line break repair, cable connectors are core components that enable rapid connection of conductors and ensure stable power transmission. Their connection reliability directly affects the safety and continuity of power supply. Currently, conventional cable connectors mainly consist of a sleeve, clamps, and elastic elements: the sleeve has through holes with a diameter decreasing from the center to both ends; two sets of clamps are installed at the ends of the sleeve; and the elastic elements work with the clamps to secure the conductors. However, conventional connectors have significant drawbacks: the sleeve's perimeter is closed, making it impossible for users to directly judge the conductor insertion depth; if the insertion is insufficient, the connection strength between the conductor and the connector is inadequate, and under stress and vibration, the conductor is prone to loosening, leading to power outages or even safety accidents.

[0003] To address the issue of the inability to see the insertion depth of the wire, existing technologies have developed targeted improvements. For example, the "Wire Connector" disclosed in application number 201820056207.4 (authorization announcement number CN207765629U) includes a transmission component positioned between two sets of wire clamps within a sleeve, connected by a first elastic element. A viewing window is provided on the sleeve wall corresponding to the movement range of the transmission component. In some embodiments, a rod, slider, or position lever is also provided on the transmission component to aid in observing its position. During use, the wire extends into the sleeve, pushing the transmission component. The user observes the displacement of the transmission component through the viewing window, indirectly determining whether the wire is inserted correctly, thus alleviating the problem of unknown insertion depth to some extent.

[0004] However, this solution still has obvious shortcomings: the positioning recognition relies entirely on additional components such as transmission components, the first elastic component, the rod and the slider, which not only increases the structural complexity and the number of parts, but also increases the manufacturing cost and assembly difficulty; moreover, the cooperation of multiple components is prone to the transmission components tilting due to the deviation of the wire insertion posture, or jamming and wear caused by the accumulation of environmental impurities, affecting the accuracy and long-term reliability of positioning recognition, making it difficult to balance structural simplicity and usage stability.

[0005] In summary, existing cable connectors either suffer from the drawback of unclear insertion depth, or their improved solutions are complex and prone to failure due to reliance on multiple components. Therefore, there is an urgent need to develop a stable cable connector that eliminates the need for transmission components, simplifies the structure, and provides a clear indication of the insertion position. This would ensure efficient power operations and power supply safety, while also improving product economy and reliability. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a cable connector with a simplified structure, which can intuitively indicate the insertion status of the wire without the need for transmission components, and provides a stable connection, in light of the above-mentioned technical status.

[0007] The technical solution adopted by this utility model to solve the above problems is as follows: the cable connector includes a sleeve and a wire clamp disposed in the sleeve, the sleeve has an axially extending wire hole, and also includes a connecting sleeve and an identification element;

[0008] The connecting sleeve is built into the sleeve and has a plug-in channel for the cable to pass through. The identification element is rotatably disposed on the connecting sleeve and includes a trigger part and an identification part. The identification part is located in the plug-in channel. The sleeve wall has a through hole.

[0009] With the cable inserted into the plug channel and the trigger part pushed, the identification element rotates around its rotation axis, causing the identification part to extend outward from the through hole to indicate that the cable is inserted in place.

[0010] To ensure the efficiency and stability of the movement of the identification component and to simplify its transmission structure, preferably, the identification component is provided with a hinge shaft located at the connection between the trigger part and the identification part, so that the identification component forms a lever structure.

[0011] To facilitate the installation and positioning of the identification component and ensure its smooth rotation under stress, preferably, the connecting sleeve is provided with a groove communicating with the insertion channel, the bottom of the groove is formed with an inclined surface, and a hinge hole adapted to the hinge shaft is opened on the inclined surface, and the trigger part of the identification component extends into the insertion channel through the groove.

[0012] To provide a clearer and more intuitive indication of cable insertion, preferably, the identification unit includes a link and an indicator arrow. One end of the link is connected to the trigger unit, and the indicator arrow is connected to the other end of the link and arranged perpendicular to the link. When the cable is inserted, the direction of the indicator arrow is consistent with the insertion direction of the cable.

[0013] To lock the identification component when the cable is not inserted and prevent it from rotating due to vibration or accidental contact, preferably, the connecting sleeve is also provided with a limiting groove that extends axially and penetrates the insertion channel. The width of the limiting groove is adapted to the width of the indicator arrow. The side of the indicator arrow is provided with a corresponding slot of the limiting groove. When the cable is not inserted, the slot engages with the edge of the limiting groove to lock the identification component.

[0014] To enhance the structural strength and operational reliability of the identification component and optimize its lever transmission effect, preferably, the trigger part and the identification part of the identification component are integrally formed, and the included angle α between the two is 120° to 150°.

[0015] To ensure that the cable can be smoothly inserted and reliably push the trigger part, while avoiding excessive friction or jamming with the inner wall of the channel, preferably, the cross-section of the insertion channel is adapted to the contour of the trigger part, and a gap is left between the inner wall of the insertion channel and the trigger part.

[0016] To adapt to the application scenario of dual-cable docking and to accurately control the final position of the identification component in the in-position state, preferably, both ends of the connecting sleeve are provided with the insertion channel, and a horizontally extending baffle is provided between the two insertion channels. When the cable is inserted in the in-position state, the trigger part of the identification component abuts against the baffle to limit the identification component from excessive rotation. In this state, the connecting rod is in a vertical state and the indicator arrow is in a horizontally extending state.

[0017] To achieve synchronous or independent indication of the connection status of two cables and effectively avoid interference between the two identification components in spatial layout, preferably, two sleeves are provided, which are connected to each other. The two ends of the connecting sleeve are respectively fitted into the two sleeves, and the two insertion channels form a passage for the two cables to be inserted from both ends respectively. Two identification components are provided, located on the upper and lower sides of the connecting sleeve respectively, and the two identification components are staggered in the axial direction. The direction of the indicator arrow of each identification component is consistent with the insertion direction of the corresponding cable.

[0018] Compared with the prior art, the advantages of this utility model are as follows: By setting a rotatable identification element on the connecting sleeve, and making the identification element include a trigger part that extends into the insertion channel and an identification part that can rotate with it, and at the same time cooperating with the through hole opened on the sleeve, since the identification element is designed as a single lever structure that rotates around the hinge axis, and the identification part is driven to extend outward from the through hole by the direct push of the trigger part when the cable is inserted, it is not necessary to rely on multiple components such as transmission components and elastic components as in the prior art. The positioning indication can be achieved by the simple movement of a single identification element. This not only greatly simplifies the internal structure, reduces manufacturing costs and assembly difficulty, but also avoids reliability problems caused by jamming and wear of multiple components. At the same time, it provides the operator with an intuitive visual signal that can quickly and accurately judge whether the cable is inserted in place from the outside, effectively preventing poor connection and safety risks caused by improper insertion.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Figures 1-8 The figure shown is the preferred embodiment of this utility model.

[0029] The cable connector in this embodiment mainly includes a sleeve 1, a clamp 2, a connecting sleeve 3, and an identification element 4. Through the structural design of "connecting sleeve 3 adapting to the docking of double sleeves 1", combined with the visualization function of "identification element 4 hinged rotation + indicator arrow indication", it effectively solves the problems of difficulty in judging the insertion status of existing cable connectors and lack of clear positioning marks after docking at both ends. At the same time, through the locking cooperation of the limiting groove and the card slot, and the excessive flipping limitation of the baffle, it takes into account both operational convenience and structural stability, and meets the scenario requirements of rapid cable docking and intuitive status identification.

[0030] The structure and connection relationships of each component are as follows:

[0031] Sleeve 1: Reference Figures 1 to 4As shown, sleeve 1 is the outer shell support component of this embodiment. There are two sleeves, both of which are hollow cylindrical structures. The two sleeves 1 can be connected to each other axially through a snap-fit ​​or threaded structure to form a complete outer shell. Each sleeve 1 has an axially extending wire hole 1a inside. The diameter of the wire hole 1a is adapted to the outer diameter of the cable for the cable to pass through. At the same time, the wall of the sleeve 1 has a through hole 1b. The through hole 1b is elongated and its size is adapted to the indicator arrow 4b2 of the identification element 4, so that the identification part 4b of the identification element 4 can extend outward to indicate the status. At both ends of the sleeve 1, there are also outwardly flared connectors 5 to facilitate the user to pass the cable through. When the cable connector of this embodiment is used to connect two cables, the wire hole 1a inside the sleeve 1 is axially through, and two sets of wire clamps 2, identification elements 4, etc. are symmetrically arranged inside the sleeve 1. Based on the symmetrical structure, the two cables are stably connected inside the sleeve 1.

[0032] Cable clip 2: Reference Figures 1 to 4 As shown, the wire clamp 2 is built into and fixed in the wire hole 1a of the sleeve 1, and can be limited by interference fit or inner wall protrusion; during the insertion of the cable, the wire clamp 2 will move towards the center of the wire hole 1a. After the cable is inserted into place, the wire clamp 2 can clamp the cable to prevent the cable from loosening and falling off after docking.

[0033] Connecting sleeve 3: Reference Figures 3 to 7 As shown, the connecting sleeve 3 is an integral hollow structure, with its two ends respectively fitted inside the two mated sleeves 1. The positioning protrusions on the outer wall cooperate with the positioning grooves on the inner wall of the sleeve 1 to achieve axial fixation between the connecting sleeve 3 and the sleeve 1, preventing relative sliding. Both ends of the connecting sleeve 3 are provided with insertion channels 3a, which are coaxial with the wire holes 1a of the sleeve 1. The diameter of the holes is slightly larger than the outer diameter of the cables. The two insertion channels 3a are axially connected along the connecting sleeve 3, forming a passage for two cables to be inserted and mated from both ends. A baffle 3f is provided between the two insertion channels 3a. The baffle 3f extends laterally and is integrally formed on the inner wall of the connecting sleeve 3, and its two ends can abut against the touch part 4a of the identification member 4. On the outer wall of the connecting sleeve 3, a recessed groove 3c is provided corresponding to the position of each identification member 4. The groove 3c is connected to the insertion channel 3a. The bottom of the groove 3c is also formed with a slope 3h. The inclination angle of the slope 3h is adapted to the lever rotation trajectory of the identification member 4. A hinge hole 3d is provided on the slope 3h. The diameter of the hinge hole 3d is adapted to the hinge shaft 3b of the identification member 4. In addition, a limiting groove 3e is provided on the outer wall of the connecting sleeve 3, extending axially and penetrating the insertion channel 3a. The width of the limiting groove 3e is the same as the width of the indicator arrow 4b2 of the identification member 4. Since the limiting groove 3e penetrates into the interior of the connecting sleeve 3, the edge of the limiting groove 3e can be engaged in the slot 4b2a of the indicator arrow 4b2.

[0034] Identification component 4: Reference Figures 3 to 8As shown, there are two identification elements 4, located on the upper and lower sides of the connecting sleeve 3 respectively, and they are staggered in the axial direction to avoid mutual interference during rotation. Each identification element 4 includes a triggering part 4a and an identification part 4b, which are integrally formed, and the included angle α between them is 120° to 150°. In this embodiment, 140° is preferred to ensure that the lever structure can rotate smoothly after being subjected to force. The triggering part 4a is plate-shaped and extends into the insertion channel 3a through the groove 3c of the connecting sleeve 3. Its cross-sectional profile is adapted to the inner wall profile of the insertion channel 3a, and an appropriate gap is left between the triggering part 4a and the inner wall of the insertion channel 3a to avoid interference between the identification element 4 and the channel wall when rotating. The identification part 4b includes a connecting rod 4b1 and an indicator arrow 4b2. The connecting rod 4b1 is a long rod-shaped rod, one end of which is integrally connected to the end of the triggering part 4a, and the other end is perpendicularly connected to the indicator arrow 4b2 at a vertical angle of 90° to ensure that the indicator arrow... The head is clearly pointed out. The two sides of the indicator arrow 4b2 are integrally formed with slots 4b2a. The shape of the slots 4b2a is adapted to the edge of the limiting groove 3e of the connecting sleeve 3 and can be inserted into the limiting groove 3e. The identification part 4 is provided with a hinge shaft 3b. The hinge shaft 3b is located at the connection between the trigger part 4a and the identification part 4b (that is, the connection position between the connecting rod 4b1 and the trigger part 4a). The hinge shaft 3b is inserted into the hinge hole 3d of the connecting sleeve 3 to realize the rotation of the identification part 4 around the hinge shaft 3b, so that the identification part 4 as a whole forms a lever structure.

[0035] The working principle of the cable connector in this embodiment is explained as follows:

[0036] 1. Initial state with cable not inserted: The two sleeves 1 are fixed together, and the connecting sleeve 3 is fitted inside the two sleeves 1. The identification element 4 is hinged to the connecting sleeve 3 through the hinge shaft 3b. At this time, the side slot 4b2a of the indicator arrow 4b2 of the identification element 4 is engaged in the limiting slot 3e of the connecting sleeve 3, and the identification element 4 is locked. The trigger part 4a is inserted into the channel 3a, and the connecting rod 4b1 of the identification part 4b and the indicator arrow 4b2 are housed in the gap between the connecting sleeve 3 and the sleeve 1. The indicator arrow 4b2 does not protrude from the through hole 1b of the sleeve 1, and there is no external indication of the position.

[0037] 2. Cable insertion and identification unlocking: Insert the first cable through the wire hole 1a of one of the sleeves 1, pass through the wire clamp 2 and the sleeve 1 in sequence, and enter the corresponding side insertion channel 3a of the connecting sleeve 3; as the cable continues to be inserted, its end contacts the touch part 4a of the identification 4 and applies a pushing force. Since the identification 4 is a lever structure, the touch part 4a is driven by the force to rotate the identification 4 around the hinge axis 3b. The slot 4b2a of the indicator arrow 4b2 disengages from the limiting slot 3e, the identification 4 unlocks and continues to rotate.

[0038] 3. Cable Insertion and Status Indication: When the cable is fully inserted into the set position, the end of the trigger 4a will abut against the baffle 3f of the connecting sleeve 3. The baffle 3f will prevent the trigger 4a from moving further and limit the identification element 4 from over-rotating. At this time, the identification element 4 rotates to the limit position, the connecting rod 4b1 is in a vertical state, the indicator arrow 4b2 is in a horizontally extended state, and the indicator arrow 4b2 extends outward from the through hole 1b of the sleeve 1. The direction of the indicator arrow is consistent with the direction of cable insertion, which visually indicates that the cable on this side has been inserted into place. At the same time, the wire clamp 2 in the sleeve 1 clamps the cable through elastic deformation to prevent the cable from loosening.
