Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a stable anti-detachment connector. Background Technology

[0002] Currently, signal and power transmission between electronic devices widely relies on connecting cables such as data cables and power cords. Existing technologies often use a single clip or friction to prevent detachment in conventional connecting cables. These simple, single-point anti-detachment structures are prone to clip breakage or loosening and detachment after lateral pulling, vibration, or prolonged use. This can lead to equipment downtime, signal interruption, or even safety hazards. Furthermore, some connecting cables lack effective stress-absorbing structures at the plug-to-cable connection, making them susceptible to internal wire breakage or sheath damage from frequent pulling, shortening their lifespan. In addition, traditional connecting cables have imperfect plug-in guiding structures, leading to issues like misalignment and incorrect insertion during connection. This not only affects operational efficiency but can also cause deformation of the pins and plugs due to hard contact, damaging the connection structure. Moreover, some anti-detachment structures are designed to be too tight for stability, requiring tools for disassembly, which is inconvenient. Additionally, some anti-detachment components lack lightweight design considerations, resulting in a heavy overall weight for the connecting cable, making installation and carrying difficult and failing to meet the demands of industrial and electronic fields for high stability, long lifespan, and ease of operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] like Figures 1 to 4 The image shows an embodiment of the present invention, relating to a stable anti-detachment connector cable, including a connector cable body 10. The connector cable body 10 includes a first plug 20, a second plug 30, and a cable 11 for electrically or signal connecting the first plug 20 and the second plug 30. The side wall of the first plug 20 is provided with a first anti-detachment plug 40. The first anti-detachment plug 40 includes a first connecting part 41, a first side insert 50 and a second side insert 60 respectively connected to both ends of the first connecting part 41, and a central insert 70 connected to the central area of ​​the first connecting part 41. The side wall of the second plug 30 is provided with a second anti-detachment plug 80 adapted to be inserted into the first anti-detachment plug 40. The second anti-detachment plug 80 includes a second connecting part 81 and an anti-detachment box 90 connected to one side of the second connecting part 81. The anti-detachment box 90 is respectively inserted into and cooperates with the first side insert 50, the second side insert 60, and the central insert 70.

[0035] Specifically, the connecting cable body 10 serves as the basic load-bearing structure of the connecting cable. The first plug 20 and the second plug 30 respectively enable the connection with external devices. The cable 11 directly ensures the stable transmission of electrical signals or power between the first plug 20 and the second plug 30, avoiding equipment shutdown or signal loss due to transmission path interruption. At the same time, the integrated design of the three ensures the integrity of the overall structure of the connecting cable, providing a stable foundation for the subsequent installation of the anti-detachment structure.

[0036] The first connecting part 41 integrates the first side insert 50, the second side insert 60, and the central insert 70 into one unit, ensuring that the three move synchronously and are evenly stressed, avoiding the impact of a single insert offset on the anti-detachment effect; the first side insert 50 and the second side insert 60 on both sides form symmetrical lateral support, while the central insert 70 provides axial positioning. The three work together to form an anti-detachment support structure, which greatly improves the anti-detachment stability compared to the traditional single-point anti-detachment, effectively resisting lateral pulling and axial loosening; and the insert-type structure design can be completed without additional tools, taking into account both stability and ease of operation.

[0037] The second connecting part 81 provides a stable mounting carrier for the anti-detachment box 90, ensuring that the anti-detachment box 90 and the second plug 30 are fixed synchronously, and avoiding misalignment between the anti-detachment structure and the plug body. The plug-in adaptation design of the anti-detachment box 90 and the first anti-detachment plug 40 realizes the precise docking of the plug and the box, which not only restricts the relative displacement of the first plug 20 and the second plug 30, but also forms a rigid constraint through the physical plug-in structure. Even in the case of vibration, collision or accidental pulling, it can effectively prevent the plug from falling off and ensure the continuous operation of the equipment.

[0038] like Figure 1 As shown, the first plug 20 includes a first insertion portion 21 and a first transition portion 22; the insertion surface of the first insertion portion 21 has a plurality of insertion holes 23; one end of the first transition portion 22 is fixedly connected to the side of the first insertion portion 21 away from its insertion end surface, and the other end of the first transition portion 22 is fixedly connected to one end of the cable 11. Specifically, the precise arrangement of the insertion holes 23 ensures a one-to-one correspondence with the external device interface or the pins 34 of the second plug 30, avoiding poor contact due to hole misalignment, and ensuring the accuracy and reliability of electrical or signal connections; the first transition portion 22 connects the first insertion portion 21 and the cable 11, and its structural design can buffer the stress at the connection between the cable 11 and the plug. When the cable 11 is pulled, the transition portion can disperse the force, avoiding stress concentration that could cause the internal wires of the cable 11 to break or the outer sheath to be damaged, significantly extending the service life of the connection cable, especially suitable for use scenarios such as industrial equipment wiring and portable electronic device connections that involve frequent movement or pulling.

[0039] like Figure 1 and Figure 3As shown, the second plug 30 includes a second insertion portion 31 and a second transition portion 32; the second insertion portion 31 has an axially extending insertion groove 33 inside, and the insertion groove 33 has a plurality of pins 34 that correspond one-to-one with and are adapted to be inserted into a plurality of sockets 23. The pins 34 are used to form an electrical connection or a signal connection with the sockets 23; one end of the second transition portion 32 is fixedly connected to the side of the second insertion portion 31 away from the insertion groove 33, and the other end of the second transition portion 32 is fixedly connected to the other end of the cable 11. Specifically, the insertion slot 33 provides a protective cavity for the pin 34, preventing the pin 34 from being exposed to dust, moisture, or physical impact, thus ensuring the conductivity and structural integrity of the pin 34. The one-to-one correspondence between the pin 34 and the socket 23 of the first plug 20 ensures a tight electrical or signal connection after they are plugged in, reducing contact resistance and avoiding signal attenuation and unstable power supply caused by poor contact. The second transition part 32 works in conjunction with the first transition part 22 to buffer the stress at the connection between the cable 11 and the second plug 30, further improving the overall tensile strength of the connecting cable, preventing the cable 11 from falling off the second plug 30 end, and ensuring the continuity of the transmission path.

[0040] like Figure 2 As shown, the free end of the first side insert 50 away from the first connecting part 41 is provided with a first snap-fit ​​platform 51 that protrudes radially outward. The side of the first snap-fit ​​platform 51 facing the insertion direction is provided with a first guide slope 52 that is inclined along the insertion guide. The bottom of the side of the first side insert 50 near the central insert 70 is provided with a first reinforcing rib 53. The first reinforcing rib 53 extends from its root to a position near the first snap-fit ​​platform 51 along the length direction of the first side insert 50. Specifically, the first locking platform 51 protrudes radially outward, and in the insertion state, it can form a mechanical locking with the locking hole 93 of the anti-detachment box 90. The interlocking structure between the protrusion and the hole restricts the reverse disengagement of the first side insert 50, forming a reliable anti-detachment lock. The first guide slope 52 is inclined along the insertion direction, which can guide the first side insert 50 to slide smoothly into the anti-detachment cavity 92 during the insertion process, reduce the insertion resistance, avoid structural damage caused by the insert jamming, and improve the ease of operation. The first reinforcing rib 53 extends along the length of the first side insert 50, from the root to the position near the first locking platform 51, which effectively enhances the structural rigidity of the insert and prevents the insert from bending or breaking when inserted, locked, or pulled by external force, ensuring the long-term effectiveness of the anti-detachment structure.

[0041] like Figure 2As shown, the free end of the second side insert 60 away from the first connecting part 41 is provided with a second snap-fit ​​platform 61 that protrudes radially outward. The side of the second snap-fit ​​platform 61 facing the insertion direction is provided with a second guide slope 62 that is inclined along the insertion guide. The bottom of the side of the second side insert 60 near the central insert 70 is provided with a second reinforcing rib 63. The second reinforcing rib 63 extends from its root to a position near the second snap-fit ​​platform 61 along the length direction of the second side insert 60. Specifically, the second locking platform 61 is symmetrically arranged with the first locking platform 51, and forms a locking fit with the corresponding locking hole 93 of the anti-detachment box 90, so that the force on both sides of the first anti-detachment plug 40 is balanced, avoiding tilting or loosening of the anti-detachment structure due to locking on one side, and further improving the anti-detachment stability; the second guide slope 62 works in concert with the first guide slope 52 to ensure that the first anti-detachment plug 40 is smoothly inserted into the anti-detachment box 90 along the preset direction, avoiding insertion failure or structural wear caused by the plug strip offset; the second reinforcing rib 63 has the same structure as the first reinforcing rib 53, which enhances the deformation resistance of the second side plug strip 60, and together with the first reinforcing rib 53, ensures the structural strength of the plug strips on both sides and extends the service life of the anti-detachment plug.

[0042] like Figure 2 As shown, the central insert 70 has integrally formed guide reinforcing ribs 71 on both sides along its length direction. The guide reinforcing ribs 71 intersect perpendicularly with the length direction of the central insert 70, forming a cross-shaped insertion structure. The free end of the guide reinforcing rib 71 has a third guide slope 72 inclined along the insertion direction. Specifically, the guide reinforcing ribs 71 intersect perpendicularly with the central insert 70 to form a cross-shaped insertion structure. On the one hand, the cross-shaped structure improves the radial rigidity of the central insert 70, preventing the insert from bending during insertion. On the other hand, the cross-shaped structure can precisely match the cross-shaped guide hole 95 of the anti-detachment box 90, forming axial positioning, avoiding twisting or offset of the first anti-detachment plug 40 and the second anti-detachment plug 80 during insertion, ensuring accurate insertion path. The third guide slope 72 is inclined along the insertion direction, playing a guiding role when the central insert 70 is inserted, reducing the frictional resistance between the insert and the cross-shaped guide hole 95, reducing the difficulty of insertion operation, and avoiding structural damage caused by hard contact, thus improving the smoothness and safety of the insertion process.

[0043] like Figure 1 and Figure 4As shown, weight-reducing holes 91 are respectively provided through the two opposite outer walls of the anti-detachment socket 90. The weight-reducing holes 91 are rectangular through holes, and their length direction is consistent with the length direction of the anti-detachment socket 90. Specifically, the weight-reducing holes 91 are rectangular through holes and are set along the length direction of the anti-detachment socket 90. Without reducing the structural strength of the anti-detachment socket 90, the amount of material used in the socket is effectively reduced, the production cost and the overall weight of the connecting cable are reduced, and the connecting cable is easier to carry and install. At the same time, the rectangular through hole structure can increase the heat dissipation area of ​​the anti-detachment socket 90, avoid the accumulation of heat generated by contact friction during the insertion process, and prevent heat from affecting the performance of the socket material or the stability of surrounding components, which is especially suitable for scenarios with long-term power supply. In addition, the weight-reducing holes 91 can also reduce material waste in the socket processing, simplify mold design, and improve production efficiency.

[0044] like Figure 3 As shown, the anti-detachment insert box 90 has an axially extending anti-detachment cavity 92 inside. The inner side walls on both sides of the anti-detachment cavity 92 are respectively provided with snap-fit ​​holes 93 that communicate with the anti-detachment cavity 92. The position of the snap-fit ​​hole 93 corresponds one-to-one with the first snap-fit ​​platform 51 of the first side insert 50 and the second snap-fit ​​platform 61 of the second side insert 60. The diameter of the snap-fit ​​hole 93 is adapted to the protrusion size of the first snap-fit ​​platform 51 and the second snap-fit ​​platform 61, so as to form a snap-fit ​​engagement with the first snap-fit ​​platform 51 or the second snap-fit ​​platform 61 in the insertion state. Specifically, the anti-detachment cavity 92 extends axially to provide space for the insertion strip of the first anti-detachment plug 40. The side wall of the cavity restricts the lateral displacement of the insertion strip, ensuring that the insertion strip maintains a stable posture after insertion. The locking hole 93 corresponds one-to-one with the first locking platform 51 and the second locking platform 61 and is sized to fit them. In the insertion state, it forms a tight locking with the locking platform. The mechanical locking structure prevents the insertion strip from coming out in the opposite direction. Even when subjected to a large external force, the locking engagement can remain stable, preventing the plug from accidentally falling off. At the same time, the locking hole 93 penetrates the side wall of the anti-detachment cavity 92, making it easy to press the locking platform out of the hole when disassembly is required. This balances anti-detachment stability and disassembly convenience, avoiding disassembly difficulties or structural damage caused by an overly tight anti-detachment structure.

[0045] like Figure 3As shown, the anti-detachment cavity 92 has a horizontally arranged partition 94 at its front opening facing the insertion direction. A cross-shaped guide hole 95 is provided through the central area of ​​the partition 94. The shape of the cross-shaped guide hole 95 is adapted to the cross-shaped insertion structure of the central insert 70, and is used to guide the central insert 70 to be inserted into the anti-detachment cavity 92 along a preset path during the insertion process. Specifically, the partition 94 is set at the front opening of the anti-detachment cavity 92 to prevent impurities from entering the cavity, avoiding foreign objects from affecting the fitting accuracy between the insert and the snap-fit ​​hole 93, and ensuring the reliability of the anti-detachment structure. The cross-shaped guide hole 95 in the center of the partition 94 is precisely adapted to the cross-shaped insertion structure of the central insert 70, providing a clear guide path for the central insert 70 during the insertion process, preventing the insert from shifting or being misinserted, and ensuring that the central insert 70 is inserted into the anti-detachment cavity 92 along a preset axis. At the same time, the cross-shaped structure can restrict the circumferential rotation of the central insert 70, further improving the docking accuracy between the first anti-detachment plug 40 and the second anti-detachment plug 80.

[0046] like Figure 3 As shown, the partition 94 has guide interfaces 96 at both ends, corresponding one-to-one with the first side insert 50 and the second side insert 60. The guide interfaces 96 guide the first side insert 50 or the second side insert 60 along a preset path into the anti-detachment cavity 92 during insertion. Specifically, the guide interfaces 96 correspond one-to-one with the first side insert 50 and the second side insert 60, providing independent guide channels for the two side inserts during insertion, preventing mutual interference or misalignment, and ensuring that the first side insert 50 and the second side insert 60 are inserted into the anti-detachment cavity 92 along the preset path. Simultaneously, the aperture of the guide interfaces 96 is adapted to the size of the inserts, allowing for initial positioning of the inserts at the beginning of insertion, reducing friction between the inserts and the inner wall of the anti-detachment cavity 92, reducing structural wear, improving the smoothness of the insertion process, and ensuring precise alignment of the two side inserts with the snap-fit ​​holes 93 after insertion, guaranteeing the reliability of the snap-fit ​​engagement.

[0047] The working principle of this utility model is as follows:

[0048] In use, align the first insertion part 21 of the first plug 20 with the second insertion part 31 of the second plug 30, and simultaneously push the first anti-detachment plug 40 and the second anti-detachment plug 80 to engage: First, guided by the third guide slope 72, the central insert 70 is inserted into the anti-detachment cavity 92 through the cross-shaped guide hole 95 in the center of the partition 94. The cross-shaped structure restricts the circumferential rotation of the central insert 70, achieving initial positioning; at the same time, guided by the first guide slope 52 and the second guide slope 62, the first side insert 50 and the second side insert 60 slide into the anti-detachment cavity 92 through the corresponding guide insertion interface 96 of the partition 94, respectively. The guide insertion interface 96 ensures the accurate path of the inserts on both sides; as the insertion depth increases, the first locking platform 51 of the first side insert 50 and the second locking platform 61 of the second side insert 60 gradually slide to the locking hole 93 position on the inner wall of the anti-detachment cavity 92, due to the locking... The protrusion size of the platform matches the diameter of the snap-fit ​​hole 93. The snap-fit ​​platform elastically snaps into the snap-fit ​​hole 93, forming a mechanical lock to prevent the first anti-detachment plug 40 and the second anti-detachment plug 80 from separating in the opposite direction, thus completing the anti-detachment fixation. At this time, the first plug part 21 plug hole 23 and the second plug part 31 pin 34 are precisely connected to form an electrical connection or signal connection. The cable 11 transmits power or signal stably through the stress buffering effect of the first transition part 22 and the second transition part 32. When disassembly is required, press the corresponding snap-fit ​​hole 93 position on the outside of the anti-detachment plug box 90 to make the snap-fit ​​platform disengage from the snap-fit ​​hole 93, and pull the first plug 20 and the second plug 30 in the opposite direction to separate them. Throughout the process, the first reinforcing rib 53, the second reinforcing rib 63, and the guide reinforcing rib 71 ensure the rigidity of the plug, the weight reduction hole 91 achieves lightweighting and heat dissipation, the partition 94 prevents foreign objects from entering, and all components work together to ensure stable connection and smooth operation.

[0049] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
