Description

Technical Field

[0001] The present invention relates to the technical field of electronic connectors, and particularly to an anti-detachment electronic connector. Background Art

[0002] As a core component in an electrical system, electronic connectors are widely used in fields such as consumer electronics, automotive industry, communication equipment, and aerospace. Their core function is to achieve reliable connection and signal transmission between circuits. With the increasing demand for device miniaturization, high-density integration, and complex working conditions (such as vibration, high temperature, and dusty environment), the anti-detachment performance of connectors has become a key indicator to ensure the stable operation of the system.

[0003] Most of the existing circular electronic connectors on the market prevent detachment mainly through a threaded locking method. However, with only a single threaded locking method, during the long-term use of the electronic connector, due to external vibration factors, the threads are likely to become loose, resulting in poor anti-detachment effect. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-detachment electronic connector to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An anti-detachment electronic connector includes a male head and a female head. The male head is inserted into the female head. The male head includes a male head body, and the female head includes a female head body. The male head further includes a force feedback component II and a locking mechanism. A force feedback component II and a locking mechanism are fixedly installed on the outer side of the male head body. A fixing ring is fixedly installed on one side of the locking mechanism close to the force feedback component II. The female head further includes an alloy ring and a force feedback component I. An alloy ring and a force feedback component I are fixedly installed on the female head body. The force feedback component I corresponds to the force feedback component II. Through the cooperative action between the locking mechanism and the force feedback component I and the force feedback component II, the male head and the female head can be firmly connected.

[0006] Further, the male head body includes a wire clamp, a housing, a male head plastic seat, male pins, jacks, and a fastening ring. The wire clamp is fixedly connected to the housing on one side close to the force feedback component II. The male head plastic seat is fixedly connected to the inside of the housing. Evenly distributed male pins are fixedly installed inside the male head plastic seat. Jacks corresponding to the male pins are opened on the male head plastic seat. The fastening ring is rotatably connected to the outer side of the housing.

[0007] Further, the female head body includes a female head flange seat, a docking ring, a female head plastic seat, and female pins. One side of the female head flange seat close to the force feedback component one is fixedly connected with the docking ring. The inner side of the female head flange seat is fixedly connected with the female head plastic seat. The female head plastic seat is fixedly installed with evenly distributed female pins, and the female pins correspond to the jacks. The outer side of the male head plastic seat is provided with multiple groups of bumps. The inner side of the docking ring is provided with slots corresponding to the bumps. The fastening ring is threadedly connected with the docking ring.

[0008] Further, an annular groove is formed on the outer side of the docking ring, and the alloy ring is installed in the annular groove. The alloy ring is a nickel-titanium shape memory alloy ring.

[0009] Further, the force feedback component one includes a fixed seat and a conical elastic snap ring. One side of the female head flange seat close to the male head is fixedly installed with the fixed seat. The inner side of the fixed seat is clamped with the conical elastic snap ring. The conical elastic snap ring has two sections. From the male head to the female head direction, the radius of the first section gradually increases, and the radius of the second section gradually decreases.

[0010] Further, the force feedback component two includes a connecting ring, an annular shell, and spherical bumps. One side of the fastening ring close to the female head is fixedly connected with the connecting ring. The outer side of the connecting ring is fixedly connected with the annular shell. The inner side of the annular shell is fixedly connected with evenly distributed spherical bumps, and the spherical bumps correspond to the conical elastic snap ring.

[0011] The fastening ring on the male head is docked with the female pins on the female head. At the same time, the thread on the fastening ring contacts the thread on the docking ring, and the spherical bump contacts the outer wall of the first section of the conical elastic snap ring; Further, the other side of the fixed ring is fixedly connected with the fastening ring.

[0012] The worker rotates the fastening ring, so that the fastening ring gradually locks and moves with the docking ring through the thread. During the process of the fastening ring locking and moving towards the docking ring, the fastening ring drives the annular shell to move synchronously through the connecting ring, so that the spherical bumps inside the annular shell gradually move from the first section of the conical elastic snap ring to the second section; Since the radius of the first section of the conical elastic snap ring gradually increases, when the spherical bump moves, it squeezes the conical elastic snap ring. Since the conical elastic snap ring is made of elastic material, the elastic force of the conical elastic snap ring acts on the spherical bump in the reverse direction, so that the resistance received by the worker when turning the fastening ring gradually increases. When the spherical bump moves to the second section; When the spherical bump moves to the second section, since the radius of the second section gradually decreases, the resistance received by the worker when turning the fastening ring gradually decreases. When the resistance is the smallest, the male head and the female head are docked in place; Because the spherical protrusion is in the second interval, the conical elastic snap ring can prevent the male head from being separated from the female head on the basis of thread locking. Further, the locking mechanism includes a second locking assembly, the second locking assembly includes a shift block assembly and a ratchet assembly, the outer side of the shell is fixedly connected to the ratchet assembly, the outer side of the ratchet assembly is fixedly installed with the shift block assembly, the ratchet assembly includes a ratchet ring, a circular shell, and a mounting ring, the outer side of the shell is fixedly connected to the circular shell, the outer side of the shell and the inner side of the circular shell are fixedly connected with the mounting ring, and the inner side of the mounting ring is rotatably connected with the ratchet ring; The shift block assembly includes a mounting shell, a shift block, a spring three, an operating rod, a fixed block, and a fixed column. The outer side of the circular shell is fixedly connected to the mounting shell, the outer side of the circular shell and the inner side of the mounting shell are fixedly connected to a fixed column, the fixed column is fixedly connected to the fixed block, the inner side of the fixed block is rotatably connected to the shift block, a spring three is fixedly connected between the shift block and the inner side wall of the mounting shell, an operating rod is fixedly installed on the shift block, an arc groove corresponding to the operating rod is opened on the mounting shell, the shift block corresponds to the ratchet ring, and the fixed ring is fixedly connected to the ratchet ring.

[0013] When the locking assembly 2 is used, since the ratchet ring is fixedly connected to the fastening ring through the fixing ring, the ratchet ring is driven to rotate synchronously while the fastening ring rotates, and the ratchet ring continuously moves the shift block around the fixing block through the ratchet groove thereon while rotating, and the shift block rotates back and forth around the fixing block under the action of the spring 3. When the fastening ring is twisted into place, in the later use process, when the fastening ring is twisted in the reverse direction and loosened due to the influence of external vibration, the shift block is stuck to the ratchet ring to prevent the fastening ring from loosening in the reverse direction. When the locking of the locking assembly 2 needs to be released, the staff can push the operating rod to separate the shifting block from the ratchet ring; Further, the locking mechanism includes a locking component 1, and the locking component 1 includes an elastic member and a locking member. The outer side of the wire clamp is fixedly installed with the elastic member, and the locking member is fixedly installed on the side of the elastic member close to the female head. The elastic member includes a rectangular shell, a mounting frame, a movement rod, a spring 1, a limiting rod, a conical block, and a spring 2. The outer side of the wire clamp is fixedly connected to a rectangular shell, and the side of the rectangular shell away from the female head is fixedly connected to the mounting frame. The inner sides of the rectangular shell and the mounting frame are slidably connected to the movement rod, and a spring 1 is sleeved between the movement rod and the inner side wall of the mounting frame. The inner side of the rectangular shell is slidably connected to the limiting rod, and a spring 2 is sleeved between the limiting rod and the inner side wall of the rectangular shell. A conical block is fixedly connected to the movement rod, and the conical block corresponds to the limiting rod.

[0014] Further, the locking member includes a semi-circular connecting ring, a connecting block, a first locking ring, and a second locking ring. A semi-circular connecting ring is fixedly connected to the side of the moving rod close to the female head. A connecting block is fixedly connected to the side of the semi-circular connecting ring close to the female head. A first locking ring is fixedly connected to the side of the connecting block close to the female head. A second locking ring is fixedly connected to the side of the fixed ring close to the male head. The first locking ring corresponds to the second locking ring.

[0015] When using the first locking assembly, since the second locking ring is fixedly connected to the fastening ring through the fixed ring, the fastening ring drives the second locking ring to rotate synchronously while rotating. When the fastening ring is twisted in place, the worker pushes the moving rod, so that the conical block breaks through the restriction of the limiting rod. The moving rod drives the semi-circular connecting ring fixedly connected thereto to move towards the female head under the spring force of the first spring. The semi-circular connecting ring drives the first locking ring fixedly connected thereto to move synchronously through the connecting block. Since the first locking ring and the second locking ring are provided with corresponding tooth grooves, after the first locking ring and the second locking ring come into contact, they are in a meshing state, thereby preventing the fastening ring from reversing and loosening. When unlocking is required, the worker pulls the moving rod to reset the conical block, and the first locking ring and the second locking ring separate.

[0016] Compared with the prior art, the present invention provides an anti-detachment electronic connector, which has the following beneficial effects: 1. The anti-detachment electronic connector realizes the locking purpose of preventing the loosening of the threaded connection on the basis of two groups of threads through the cooperation between the first locking assembly and the second locking assembly, changes the existing single-thread locking anti-detachment method, makes the locking have double guarantees, and at the same time, the two locking methods can be arbitrarily matched according to the actual application situation, greatly improving the anti-detachment effect of the electronic connector.

[0017] 2. The anti-detachment electronic connector, through the cooperation between the first force feedback assembly and the second force feedback assembly, enables the first interval and the second interval of the conical elastic snap ring to have two-stage force feedback on the worker's twisting of the fastening ring, thereby realizing that at the initial stage and the end stage of the connection of the electronic connector, the worker can clearly know through the force feedback, the operating hand feel is obvious, preventing the situation of the knob not in place or over-twisting. At the same time, the conical elastic snap ring can prevent the male head from separating from the female head on the basis of threaded locking, and further ensure that when the threaded gap increases due to the increase of the external temperature and loosening occurs, since the alloy ring is a nickel-titanium alloy memory ring, the nickel-titanium alloy memory ring expands after heating, and then the alloy ring expands to compensate for the gap and maintain the locking force.

The inner side of the female head flange seat 21 is fixedly connected to the female head plastic seat 23. The female pins 24 are fixedly installed on the female head plastic seat 23 in a uniformly distributed manner. The female pins 24 correspond to the jacks 15. Multiple groups of protrusions are provided on the outer side of the male head plastic seat 13. Slots corresponding to the protrusions are provided on the inner side of the docking ring 22. The fastening ring 16 is threadedly connected to the docking ring 22.

[0024] Furthermore, an annular groove is provided on the outer side of the docking ring 22, and the alloy ring 3 is installed in the annular groove. The alloy ring 3 is a nickel-titanium memory alloy ring.

[0025] Furthermore, the first force feedback component 4 includes a fixed seat 41 and a conical elastic snap ring 42. A fixed seat 41 is fixedly installed on one side of the female head flange seat 21 close to the male head. The conical elastic snap ring 42 is snap-fitted inside the fixed seat 41. The conical elastic snap ring 42 has two intervals.

[0028] The staff rotates the fastening ring 16, so that the fastening ring 16 gradually locks and moves with the docking ring 22 through the thread. During the process of the fastening ring 16 locking and moving towards the docking ring 22, the fastening ring 16 drives the annular shell 52 to move synchronously through the connecting ring 51, so that the spherical bump 53 inside the annular shell 52 gradually moves from the first interval of the conical elastic snap ring 42 to the second interval; Since the radius of the first interval of the conical elastic snap ring 42 gradually increases, when the spherical bump 53 moves, it squeezes the conical elastic snap ring 42. Since the conical elastic snap ring 42 is made of elastic material, the elastic force of the conical elastic snap ring 42 acts on the spherical bump 53 in the reverse direction, so that the resistance received by the operator when turning the fastening ring 16 gradually increases; When the spherical bump 53 moves to the second interval, since the radius of the second interval gradually decreases, the resistance received by the operator when turning the fastening ring 16 gradually decreases; when the resistance is the smallest, the male head and the female head are docked in place; Also, since the spherical bump 53 is in the second interval, the conical elastic snap ring 42 can prevent the male head and the female head from separating on the basis of thread locking. Furthermore, the locking mechanism includes a second locking assembly 8. The second locking assembly 8 includes a dial block assembly 81 and a ratchet assembly 82. The outer side of the housing 12 is fixedly connected with the ratchet assembly 82, and the outer side of the ratchet assembly 82 is fixedly installed with the dial block assembly 81. The ratchet assembly 82 includes a ratchet ring 821, a circular shell 822, and a mounting ring 823. The outer side of the housing 12 is fixedly connected with the circular shell 822, and the outer side of the housing 12 and inside the circular shell 822 is fixedly connected with the mounting ring 823.

A third spring 813 is fixedly connected between the dial block 812 and the inner wall of the mounting shell 811. The operating rod 814 is fixedly installed on the dial block 812. An arc-shaped groove corresponding to the operating rod 814 is formed in the mounting shell 811. The dial block 812 corresponds to the ratchet ring 821, and the fixed ring 6 is fixedly connected with the ratchet ring 821.

[0029] When the locking assembly 2 8 is used, the ratchet ring 821 is fixedly connected to the fastening ring 16 through the fixing ring 6, and the fastening ring 16 rotates, thereby driving the ratchet ring 821 to rotate synchronously. The ratchet ring 821 rotates while continuously moving the shifting block 812 around the fixing block 815 through the ratchet groove thereon to rotate back and forth under the action of the spring 3 813. When the fastening ring 16 is twisted into place, in the later use process, when the fastening ring 16 is twisted in the reverse direction and loosened due to the influence of external vibration, the shifting block 812 clamps the ratchet ring 821 to prevent the fastening ring 16 from loosening in the reverse direction. When the locking assembly 2 8 needs to be released, the staff can push the operating rod 814 to separate the shifting block 812 from the ratchet ring 821; Embodiment 2 See also Figures 12-15 The difference between the second embodiment and the first embodiment is that the locking mechanism includes a locking assembly 7, the locking assembly 7 includes an elastic member 71 and a locking member 72, the outer side of the wire clamp 11 is fixedly installed with the elastic member 71, the side of the elastic member 71 close to the female head is fixedly installed with the locking member 72, the elastic member 71 includes a rectangular shell 711, a mounting frame 712, a movement rod 713, a spring 714, a limiting rod 715, a conical block 716, and a spring 717, the outer side of the wire clamp 11 is fixedly connected with a rectangular shell 711, the rectangular A mounting frame 712 is fixedly connected to the side of the rectangular shell 711 away from the female head, a moving rod 713 is slidably connected to the inner sides of the rectangular shell 711 and the mounting frame 712, a spring 1 714 is sleeved between the moving rod 713 and the inner side wall of the mounting frame 712, a limiting rod 715 is slidably connected to the inner side of the rectangular shell 711, a spring 2 717 is sleeved between the limiting rod 715 and the inner side wall of the rectangular shell 711, a conical block 716 is fixedly connected to the moving rod 713, and the conical block 716 corresponds to the limiting rod 715.

[0030] Furthermore, the locking member 72 includes a semicircular connecting ring 721, a connecting block 722, a locking ring 1 723, and a locking ring 2 724. The moving rod 713 is fixedly connected to the semicircular connecting ring 721 on the side close to the female head, the semicircular connecting ring 721 is fixedly connected to the connecting block 722 on the side close to the female head, the connecting block 722 is fixedly connected to the locking ring 1 723 on the side close to the female head, and the fixing ring 6 is fixedly connected to the locking ring 2 724 on the side close to the male head. The locking ring 1 723 corresponds to the locking ring 2 724.

[0031] When using the first locking component 7, since the second locking ring 724 is fixedly connected to the fastening ring 16 through the fixing ring 6, the fastening ring 16 drives the second locking ring 724 to rotate synchronously while rotating. After the fastening ring 16 is turned in place, the operator pushes the moving rod 713, so that the conical block 716 breaks through the restriction of the limiting rod 715. The moving rod 713 drives the semi-circular connecting ring 721 fixedly connected thereto to move towards the female head under the spring force of the first spring 714. The semi-circular connecting ring 721 drives the first locking ring 723 fixedly connected thereto to move synchronously through the connecting block 722. Since the first locking ring 723 and the second locking ring 724 are provided with corresponding tooth grooves, after the first locking ring 723 and the second locking ring 724 come into contact, they are in a meshing state, thereby preventing the fastening ring 16 from reversing and loosening. When unlocking is required, the operator pulls the moving rod 713 to reset the conical block 716, and the first locking ring 723 and the second locking ring 724 separate from each other.

[0032] Specific usage mode and function of this embodiment: When connecting the male head and the female head, first, the fastening ring 16 on the male head is docked with the female needle 24 on the female head. At the same time, the thread on the fastening ring 16 contacts the thread on the docking ring 22, and the spherical convex block 53 contacts the outer side wall of the first section of the conical elastic clamping ring 42. The operator rotates the fastening ring 16, so that the fastening ring 16 is gradually locked and moved with the docking ring 22 through the thread. During the process of the fastening ring 16 being locked and moved towards the docking ring 22, the fastening ring 16 drives the annular shell 52 to move synchronously through the connecting ring 51, so that the spherical convex block 53 inside the annular shell 52 gradually moves from the first section of the conical elastic clamping ring 42 to the second section. Since the radius of the first section of the conical elastic clamping ring 42 gradually increases, during the movement of the spherical convex block 53, the conical elastic clamping ring 42 is extruded. Since the conical elastic clamping ring 42 is made of an elastic material, the elastic force of the conical elastic clamping ring 42 acts on the spherical convex block 53 in the reverse direction, so that the resistance received by the operator when turning the fastening ring 16 gradually increases. When the spherical convex block 53 moves to the second section, since the radius of the second section gradually decreases, the resistance received by the operator when turning the fastening ring 16 gradually decreases. When the resistance is the smallest, the male head and the female head are docked in place. Also, since the spherical convex block 53 is in the second section, the conical elastic clamping ring 42 can prevent the male head and the female head from separating on the basis of thread locking. When the locking assembly 2 8 is used, the ratchet ring 821 is fixedly connected to the fastening ring 16 through the fixing ring 6, and the fastening ring 16 rotates, thereby driving the ratchet ring 821 to rotate synchronously. The ratchet ring 821 rotates while continuously moving the shifting block 812 around the fixing block 815 through the ratchet groove thereon to rotate back and forth under the action of the spring 3 813. When the fastening ring 16 is twisted into place, in the later use process, when the fastening ring 16 is twisted in the reverse direction and loosened due to the influence of external vibration, the shifting block 812 clamps the ratchet ring 821 to prevent the fastening ring 16 from loosening in the reverse direction. When the locking assembly 2 8 needs to be released, the staff can push the operating rod 814 to separate the shifting block 812 from the ratchet ring 821; When the locking assembly 7 is used, since the locking ring 24 is fixedly connected to the fastening ring 16 through the fixing ring 6, the fastening ring 16 drives the locking ring 24 to rotate synchronously while rotating. When the fastening ring 16 is twisted into place, the staff pushes the movement rod 713 to make the conical block 716 break through the restriction of the restriction rod 715. The movement rod 713 drives the semicircular connecting ring 721 fixedly connected thereto to move toward the female head under the action of the spring 1 714. The semicircular connecting ring 721 drives the locking ring 1 723 fixedly connected thereto to move synchronously through the connecting block 722. Since the locking ring 1 723 and the locking ring 2 724 are provided with corresponding tooth grooves, the locking ring 1 723 and the locking ring 2 724 are in a meshing state after contacting, thereby preventing the fastening ring 16 from reversing and loosening. When the lock needs to be released, the staff pulls the motion rod 713 to reset the conical block 716, and the locking ring 1 723 and the locking ring 2 724 are separated.

[0033] When the thread gap increases due to the increase in external temperature and becomes loose, since the alloy ring 3 is a nickel-titanium alloy memory ring, the nickel-titanium alloy memory ring expands after heating, and then the alloy ring 3 expands to compensate for the gap and maintain the locking force.

[0034] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
