Description

Technical Field

[0001] This invention relates to the field of electrical connector equipment technology, specifically a free-end electrical connector that is resistant to loosening and strong vibration. Background Technology

[0002] A gateway is a device or program that connects different networks, protocols, or data formats; it acts as an intermediary or translator, enabling different networks to communicate and exchange data. Compared to similar devices in ordinary commercial environments, industrial gateways possess a series of unique features designed to withstand harsh industrial environments. These features are primarily designed to ensure high reliability, stability, security, and long-term durability of communication under extreme conditions.

[0003] Existing gateway connections suffer from the following problems: One of the challenges faced by existing industrial gateways is the connection status of the free-end electrical connectors. One of the most common issues with free-end electrical connectors is prolonged exposure to high-intensity vibration. High-intensity vibration can cause the electrical connector to disconnect, affecting data transmission. Existing technology discloses a vibration-resistant electrical connector (application number CN202321153574.3) that directly transmits current through the conductive posts of the pins, using a ball head to maintain a stable current flow. This eliminates the internal contact interface of the connector, avoiding poor contact between the pin and the cannula, thus solving the problem of momentary disconnection that easily occurs in vibration environments. However, this solution may experience loosening at the connection point under strong vibration. Summary of the Invention

[0004] To address the shortcomings mentioned in the background section, the present invention aims to provide a free-end electrical connector that is resistant to loosening and strong vibration.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A loose-resistant and vibration-resistant free-end electrical connector includes a female connector and a male connector. The female connector includes a socket housing, a connecting wire is connected to the rear end of the socket housing, and a socket protective shell is fixedly connected to the end of the socket housing away from the connecting wire.

[0007] The connection between the female and male connectors forms a circuit. The upper and lower ends of the contact positions of the female and male connectors are fixedly connected to auxiliary fasteners for locking and fastening the connection between the female and male connectors. The auxiliary fasteners include a fastener recess, a fixed rotating shaft is fixedly connected to the inner side of the fastener recess, a rotating plate is rotatably connected to the outer side of the fixed rotating shaft, and a snap-fit ​​ratchet is fixedly connected to the top of the rotating plate.

[0008] The auxiliary firmware at both ends of the two sides is provided with connecting firmware for fixing the connection between the female and male connectors. The connection between the female and male connectors is fixed by the auxiliary firmware and the connecting firmware.

[0009] Furthermore, the inner side of the socket protective shell is provided with multiple contact pins, and both sides of the socket shell are fixedly connected with connecting side brackets, with a connecting shaft fixedly connected between the top and bottom connecting side brackets.

[0010] Furthermore, the outer side of the connecting side frame is provided with a bottom control port and a top control port. The bottom control port is located at the end of the top control port near the connecting fastener, and the end of the connecting side frame facing the male end is provided with a fixing slot.

[0011] Furthermore, the male connector includes a plug housing, a plug terminal fixedly connected to the rear end of the plug housing, a plug connecting plate fixedly connected to the end of the plug housing away from the plug terminal, a protective shell plate fixedly connected to the end of the plug connecting plate facing the female connector at the position of the socket protective shell, a contact insertion hole opened at the end of the protective shell plate facing the female connector corresponding to the contact pin, and a fastening groove opened at the position of the plug connecting plate corresponding to the connecting side bracket, with a fastening ratchet slidably connected inside each fastening groove.

[0012] Furthermore, the bottom end of the snap-fit ​​ratchet is fixedly connected to an upper protrusion, the bottom end of the rotating plate is provided with an auxiliary plate, the inner side of the auxiliary plate is fixedly connected to a support spring, the bottom end of the auxiliary plate is slidably connected to a movable plate, the end of the movable plate away from the male head is fixedly connected to a connecting hanging plate, the end of the connecting hanging plate away from the movable plate passes through the rear end sidewall of the fastener recess and is located on the outside of the fastener recess, the top end of the movable plate is provided with a lower protrusion, and the end of the lower protrusion away from the connecting hanging plate is fixedly connected to a bearing groove.

[0013] Furthermore, two V-shaped grooves are formed at the top of the movable plate.

[0014] Furthermore, a corresponding V-shaped plate is provided at the bottom end of the auxiliary plate at the position of the V-shaped groove at the top end of the movable plate.

[0015] Furthermore, the connecting fastener includes a sliding fastener, the top of which has an L-shaped groove, a fixed shaft is fixedly connected to the inside of the L-shaped groove, a movable insert is rotatably connected to the outside of the fixed shaft, and a hook is fixedly connected to the side of the sliding fastener facing the male end.

[0016] The beneficial effects of this invention are:

[0017] This invention uses both auxiliary and connecting fasteners to prevent the electrical connector from coming loose in strong vibration environments. When the connecting fastener is locked, multiple movable plugs interact with the connecting side frame, allowing the hook and the rod of the socket slot on the outside of the plug connection plate to lock together, preventing the electrical connector at the free end of the gateway from coming loose and maintaining the connection state of the electrical connector.

[0018] By using the locking state of the auxiliary firmware, the rotating plate and the fastening ratchet cooperate to fix each other. In the locked state, the free end electrical connector of the gateway is locked. In this locked state, the movement of the fastening ratchet caused by vibration can only make the lock between the fastening ratchet and the snap-fit ​​ratchet more secure. Multiple fastening ratchets working together can provide multiple layers of protection for the electrical connector, preventing the electrical connector from loosening under strong vibration.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0033] A type of anti-loosening and anti-vibration free-end electrical connector, such as Figure 1 As shown, it includes a female connector 1 and a male connector 2. The female connector 1 and the male connector 2 are connected to form a circuit. Auxiliary fasteners 3 are fixedly connected to the upper and lower ends of both sides of the contact position of the female connector 1 and the male connector 2 to lock and tighten the connection between the female connector 1 and the male connector 2. A connecting fastener 4 is provided between the auxiliary fasteners 3 on both sides to fix the connection between the female connector 1 and the male connector 2. The connection between the female connector 1 and the male connector 2 is fixed by the auxiliary fasteners 3 and the connecting fasteners 4.

[0034] The female connector 1 and the male connector 2 are fixed together by auxiliary fasteners 3 and connecting fasteners 4 on both sides to maintain communication. The auxiliary fasteners 3 and connecting fasteners 4 work together to prevent loosening.

[0035] like Figure 2As shown, the female connector 1 includes a socket housing 11, a connecting wire 12 is connected to the rear end of the socket housing 11, a socket protective shell 13 is fixedly connected to the end of the socket housing 11 away from the connecting wire 12, a plurality of contact pins 14 are provided on the inner side of the socket protective shell 13, a connecting side bracket 15 is fixedly connected to both sides of the socket housing 11, and a connecting shaft is fixedly connected between the top and bottom connecting side brackets 15.

[0036] The industrial gateway circuit is connected via the connecting cable 12. The socket housing 11 branches the internal circuit of the connecting cable 12. The socket protective shell 13 and the contact pin 14 are used to connect with the male connector 2. The connecting side bracket 15 is used to fix the female connector 1 and the male connector 2.

[0037] like Figure 3 As shown, the connecting side frame 15 has a bottom control port 151 and a top control port 152 on its outer side. The bottom control port 151 is located at the end of the top control port 152 that is close to the connecting fastener 4. The connecting side frame 15 has a fixing slot 153 at the end facing the male head 2.

[0038] The internal structure of the auxiliary firmware 3 is controlled by the cooperation of the bottom control port 151 and the top control port 152.

[0039] like Figure 4 As shown, the male connector 2 includes a plug housing 21. A plug terminal 22 is fixedly connected to the rear end of the plug housing 21. A plug connecting plate 23 is fixedly connected to the end of the plug housing 21 away from the plug terminal 22. A protective shell plate 24 is fixedly connected to the end of the plug connecting plate 23 facing the female connector 1 at the position corresponding to the position of the socket protective shell 13. A contact insertion hole 25 is opened on the end of the protective shell plate 24 facing the female connector 1 at the position corresponding to the contact pin 14. A fastening groove 26 is opened on the plug connecting plate 23 at the position corresponding to the position of the connecting side bracket 15. A fastening ratchet 27 is slidably connected to the inner side of each fastening groove 26. Insertion slots for auxiliary fixing are opened on both sides of the plug connecting plate 23.

[0040] The signal is output through the plug terminal 22 at the rear of the plug housing 21. The plug connection plate 23 is used to fix the female head 1 and male head 2 in conjunction with the connection side bracket 15. The protective shell insert plate 24 at the front of the plug connection plate 23 is used to cooperate with the socket protective shell 13 to allow the contact socket 25 to connect with the contact pin 14, thereby realizing the connection of the industrial gateway line. The fastening ratchet 27 on the inner side of the fastening groove 26 corresponding to the fixing slot 153 is used to cooperate with the contact pin 14 to make connection.

[0041] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the auxiliary firmware 3 includes a firmware recess 31. A fixed rotating shaft 32 is fixedly connected to the inner side of the firmware recess 31. A rotating plate 33 is rotatably connected to the outer side of the fixed rotating shaft 32. A snap-fit ​​ratchet 34 is fixedly connected to the top of the rotating plate 33. An upper protrusion 35 is fixedly connected to the bottom of the snap-fit ​​ratchet 34. An auxiliary plate 36 is provided at the bottom of the rotating plate 33. A support spring 37 is fixedly connected to the inner side of the auxiliary plate 36. A movable plate 38 is slidably connected to the bottom of the auxiliary plate 36. A connecting hanging plate 311 is fixedly connected to the end of the movable plate 38 away from the male head 2. The end of the connecting hanging plate 311 away from the movable plate 38 passes through the rear side wall of the firmware recess 31 and is located on the outer side of the firmware recess 31. A lower protrusion 39 is provided at the top of the movable plate 38. A bearing groove 310 is fixedly connected to the end of the lower protrusion 39 away from the connecting hanging plate 311. Two V-shaped grooves are opened at the top of the movable plate 38. A corresponding V-shaped plate is provided at the bottom of the auxiliary plate 36 corresponding to the position of the V-shaped grooves at the top of the movable plate 38.

[0042] The fixed rotating shaft 32 inside the fastener recess 31 restricts the working state of the rotating plate 33. The support spring 37, in conjunction with the auxiliary plate 36, controls the state of the rotating plate 33. The locking ratchet 34 engages with the fastening ratchet 27, locking the fastening ratchet 27 and thus locking the plug housing 21 to the socket housing 11. The engagement between the locking ratchet 34 and the fastening ratchet 27 makes the fixation between the female connector 1 and the male connector 2 more secure. Even in complex gateway connection environments with strong vibrations, the locking between the locking ratchet 34 and the fastening ratchet 27 will only tighten, thus maintaining the connection between the female connector 1 and the male connector 2 under strong vibration. In the connected state, the auxiliary plate 36, under the action of the support spring 37, will maintain the working state of pushing the rotating plate 33 to the top, so that the locking ratchet 34 and the fastening ratchet 27 can always be in a mutually locked state. This working state is as follows: Figure 6 As shown.

[0043] When unlocking is required, the insert is inserted through the bottom control port 151 and pushed backward along the working state of the bottom control port 151, causing the moving plate 38 to be pushed rearward, allowing the V-shaped part at the bottom of the auxiliary plate 36 to move from the bottom. Figure 6 The rear end position shown is moved to, as indicated Figure 8 The front position shown allows the movable plate 38 to be maintained at the rear position. By inserting a strip into the top control port 152, the strip pushes the snap-fit ​​ratchet 34, causing the rotating plate 33 to flip to the bottom, thereby unlocking the fastening ratchet 27 and the snap-fit ​​ratchet 34, allowing the fastening ratchet 27 to move out from inside the fastener recess 31, and thus unlocking the plug housing 21 and the socket housing 11.

[0044] like Figure 9 and Figure 10As shown, the connecting fastener 4 includes a sliding fastener 41. The top of the sliding fastener 41 has an L-shaped groove 42. A fixed shaft 43 is fixedly connected to the inner side of the L-shaped groove 42. A movable insert 44 is rotatably connected to the outer side of the fixed shaft 43. A hook 45 is fixedly connected to the side of the sliding fastener 41 facing the male head 2.

[0045] The sliding fastener 41 is slidably connected to the L-shaped groove 42 via the connecting shaft between the connecting side brackets 15. After the plug housing 21 and the socket housing 11 are assembled, the sliding fastener 41 moves along the connecting shaft between the connecting side brackets 15, so that the hook 45 interacts with the rod of the socket groove on the outside of the plug connecting plate 23, so that the plug connecting plate 23 and the socket housing 11 are fixed by the hook 45. Then, the movable plug 44 is flipped outside the fixed shaft 43, so that the movable plug 44 cooperates with the connecting side bracket 15 to fix the working state of the sliding fastener 41, and the hook 45 on the outside of the sliding fastener 41 is fixed with the rod of the socket groove, thus forming an auxiliary fixation between the socket housing 11 and the plug housing 21.

[0046] In use, firstly, the socket housing 11 and plug housing 21 are plugged and fixed together according to the usage requirements of the industrial gateway to meet the connection requirements of the industrial gateway. Then, the sliding fastener 41 is pushed to move it to the rear end, so that the movable plug 44 moves to the bottom of the connecting side frame 15. Then, the movable plug 44 is rotated along the fixed axis 43 to move to the rear end of the connecting side frame 15. The hook 45 interacts with the rod of the socket slot on the outside of the plug connection plate 23 to fix the hook 45 and the rod of the socket slot, thus fixing the socket housing 11 and plug housing 21 together and maintaining the connection state of the gateway. At the same time, the four corresponding movable plugs 44 cooperate to fix it, which can also achieve a certain degree of anti-loosening.

[0047] In environments requiring strong vibration resistance, the connecting plate 311 is pushed from the rear end of the fastener recess 31 towards the inside of the fastener recess 31, causing the moving plate 38 to move inward, so that the lower protrusion 39 and the upper protrusion 35 support each other. Then, the fastening ratchet 27 corresponding to the fastener recess 31 on the outer side of the plug connecting plate 23 is pushed, allowing the fastening ratchet 27 to engage and secure with the snap-fit ​​ratchet 34. This fixing method prevents the fastening ratchet 27 from moving outward; even if movement occurs under strong vibration, it will only move inward towards the inside of the fastener recess 31, thus maintaining the connection under strong vibration and preventing the connector from breaking.

[0048] When unlocking is required, first insert the plug into the bottom control port 151 and move it from the fixed slot 153. This causes the plug to move the movable plate 38, moving it to the rear end. The connecting plate 311 then extends from the outside of the fastener recess 31, thus determining the state of the movable plate 38. At this point, the fixing between the V-shaped position at the bottom of the auxiliary plate 36 and the V-shaped groove of the movable plate 38 changes from the rear groove to the front groove. The bottom of the upper protrusion 35 of the locking ratchet 34 no longer corresponds to the lower protrusion 39 but to the bearing groove 310. Next, insert the plug into the top control port 152 and move it to the bottom of the locking ratchet 34. This unlocks the fastening ratchet 27 from the locking ratchet 34, allowing it to move outwards and unlock the socket housing 11 from the plug housing 21. The operator can then disconnect the wiring for maintenance and other operations on the gateway wiring.
