Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a quick-release connector with anti-loosening function. Background Technology

[0002] Currently, electrical connectors are widely used in aviation, aerospace, and shipbuilding industries, with applications including board-to-board, board-to-device, and device-to-device connections. With the development of electronic technology, circuit structures are becoming increasingly complex, and the structures of electrical connectors are correspondingly becoming more complex. The application scenarios and conditions for electrical connectors are also becoming more demanding, with different requirements for connectors under different operating conditions. For circuits requiring multiple electrical performance tests or equipment debugging, the connectors used need to undergo multiple mating and locking processes. Traditional threaded mating locking methods are sluggish and slow, reducing work efficiency.

[0003] Therefore, connectors in the existing technology have technical problems such as poor mating stability and difficulty in disassembly. Summary of the Invention

[0004] The present invention provides a quick-release connector with anti-loosening function, which solves the technical problems of poor connector mating stability and difficulty in disassembly in the prior art.

[0005] Some implementation schemes for solving the above-mentioned technical problems include:

[0006] A quick-release connector with anti-loosening function, including a plug;

[0007] A socket into which the plug is inserted;

[0008] and a locking assembly for locking the position of the plug relative to the socket;

[0009] The locking assembly includes a positioning ball disposed in the socket, and the plug is provided with a positioning groove that cooperates with the positioning ball to lock the position of the plug relative to the socket.

[0010] The socket is provided with a first elastic element that pushes the positioning ball into the positioning groove. The first elastic element pushes the positioning ball into the positioning groove through a push block, and the push block is slidably connected to the socket.

[0011] The plug is provided with a positioning rod for positioning the push block, the push block is provided with a positioning hole that cooperates with the positioning rod, the positioning rod is slidably connected to the plug, and a second elastic element is provided between the positioning rod and the plug to push the positioning rod into the positioning hole;

[0012] The sliding direction of the positioning rod is parallel to the direction in which the plug is inserted into the socket, and the sliding direction of the push block is perpendicular to the sliding direction of the positioning rod.

[0013] Preferably, the socket is provided with a mounting hole for mounting the positioning ball, and a retaining ring is provided at one end of the mounting hole near the positioning groove to prevent the positioning ball from dislodging from the mounting hole. The retaining ring and the socket are an integral structure.

[0014] Preferably, the push block is slidably connected to the mounting hole, and the mounting hole is further provided with a positioning post for positioning the first elastic element, and the push block and the positioning ball are in surface contact.

[0015] Preferably, the positioning post is threaded into the mounting hole, the mounting hole has an internal thread, the positioning post has an external thread that mates with the internal thread of the mounting hole, and the first elastic element is located between the positioning post and the push block.

[0016] Preferably, the first elastic element is a spring, the push block is provided with a first guide post to guide the first elastic element, a portion of the first elastic element is sleeved on the first guide post, and the positioning post is provided with a second guide post to guide the first elastic element, a portion of the first elastic element is sleeved on the second guide post.

[0017] Preferably, the second elastic element is a spring, one end of the second elastic element is fixed to the positioning rod, and the other end of the second elastic element is fixed to the plug.

[0018] Preferably, the socket is provided with a sliding hole that mates with the positioning rod, the sliding hole communicating with the mounting hole, and the sliding hole passing through one end of the socket near the plug.

[0019] Preferably, there are two positioning balls, which are located on both sides of the plug. The plug is provided with two positioning slots, each positioning slot cooperating with an independent positioning ball. Each positioning ball is pushed by an independent push block and a first elastic element. Each first elastic element is positioned by an independent positioning post. Furthermore, each push block is positioned by an independent positioning rod, and each positioning rod is provided with an independent second elastic element.

[0020] Preferably, the plug is provided with a guide hole for guiding the positioning rod, the guide hole passing through the opposite ends of the plug, and the positioning rod extends out of the end of the plug away from the socket, and a flexible connecting wire is provided between the two guide rods to facilitate the operation of the positioning rod.

[0021] Preferably, the plug is further provided with a locator for positioning the positioning rod. The locator is slidably connected to the plug. The sliding direction of the locator relative to the plug is perpendicular to both the sliding direction of the push block and the sliding direction of the positioning rod. The plug is further provided with a retaining seat for engaging the locator. The retaining seat is provided with a slot for positioning the locator. The locator is provided with a retaining block that engages with the slot.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] A secure connection between the plug and socket is achieved through the precise engagement of the positioning ball on the socket and the positioning groove on the plug. Compared to traditional threaded connections, this method is more effective at resisting vibration and impact, ensuring a stable electrical connection even under harsh working conditions. The first elastic element continuously pushes the positioning ball through a push block, ensuring it is tightly embedded in the positioning groove, further enhancing the locking force and improving the stability of the plug-socket mating. A positioning rod, under the force of the second elastic element, positions the push block. With the positioning ball engaging the positioning groove, the positioning rod positions the push block, preventing accidental movement and ensuring the plug and socket remain secure, further improving the stability of the connector mating.

[0024] When it is necessary to separate the plug and socket, simply operate the positioning rod to disengage it from the positioning hole of the push block. At this time, the side wall of the plug positioning groove relative to the socket interferes with the positioning ball and overcomes the elastic force of the first elastic element, causing the positioning ball to disengage from the positioning groove, thus allowing the plug to be easily pulled out. This process requires no rotation or complicated operations, greatly improving the efficiency of disassembly and assembly. Attached Figure Description

[0037] The specific embodiments shown below are intended to describe various configurations of the subject matter of the invention and are not intended to represent the only configuration in which the subject matter of the invention can be practiced. The specific embodiments include particular details intended to provide a thorough understanding of the subject matter of the invention. However, it will be clear and apparent to those skilled in the art that the subject matter of the invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0038] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0039] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Reference Figures 1 to 7 As shown, a quick-release connector with anti-loosening function includes a plug 1;

[0041] Socket 2, the plug 1 is inserted into the socket 2;

[0042] and locking assembly 3, the locking assembly 3 being used to lock the position of the plug 1 relative to the socket 2;

[0043] The locking assembly 3 includes a positioning ball 31 disposed in the socket 2, and the plug 1 is provided with a positioning groove 32 that cooperates with the positioning ball 31 to lock the position of the plug 1 relative to the socket 2.

[0044] The socket 2 is provided with a first elastic element 33 that pushes the positioning ball 31 into the positioning groove 32. The first elastic element 33 pushes the positioning ball 31 into the positioning groove 32 through a push block 34. The push block 34 is slidably connected to the socket 2.

[0045] The plug 1 is provided with a positioning rod 35 for positioning the position of the push block 34. The push block 34 is provided with a positioning hole 341 that cooperates with the positioning rod 35. The positioning rod 35 is slidably connected to the plug 1. A second elastic member 36 is provided between the positioning rod 35 and the plug 1 to push the positioning rod 35 into the positioning hole 341.

[0046] The sliding direction of the positioning rod 35 is parallel to the direction in which the plug 1 is inserted into the socket 2, and the sliding direction of the push block 34 is perpendicular to the sliding direction of the positioning rod 35.

[0047] Reference Figures 1 to 2 As shown, in practice, the positioning ball 31 protrudes from the socket 2 towards the positioning groove 32 under the action of the first elastic element 33. When the plug 1 mates with the socket 2, a part of the plug 1 extends into the socket 2. At this time, the plug 1 interferes with the positioning ball 31, overcoming the elastic force of the first elastic element 33 and causing the positioning ball 31 to move away from the plug 1, so that the plug 1 can be correctly mated with the socket 2.

[0048] After the plug 1 and socket 2 are properly connected, the positioning groove 32 corresponds to the positioning ball 31. Under the action of the first elastic element 33, the positioning ball 31 enters the positioning groove 32 to achieve the positioning of the plug 1 and socket 2.

[0049] However, under vibration conditions, the positioning ball 31 is positioned by the first elastic element 33 in conjunction with the push block 34. This positioning method has low positioning strength, and the positioning ball 31 may malfunction. Therefore, after the plug 1 and socket 2 are properly mated, the positioning hole 341 of the push block 34 corresponds to the position of the positioning rod 35. The positioning rod 35 enters the positioning hole 341 under the elastic force of the second elastic element 36, thus positioning the push block 34. By using the positioning rod 35 to reposition the push block 34, even under vibration conditions, the positioning ball 31 will not malfunction, thereby improving the stability of the connector mating.

[0050] Understandably, since the positioning rod 35 is driven by the second elastic element 36, the positioning rod 35 may be displaced under vibration conditions. However, as long as the positioning rod 35 does not completely detach from the push block 34, the positioning performance of the positioning rod 35 on the push block 34 will not fail, thereby effectively improving the stability of the connector mating.

[0051] When it is necessary to detach the plug 1 from the socket 2, the positioning rod 35 is operated to overcome the elastic force of the second elastic element 36, so that the positioning rod 35 is completely separated from the push block 34. At this time, the side wall of the positioning groove 32 of the plug 1 is pulled to interfere with the positioning ball 31 and overcome the elastic force of the first elastic element 33, so that the positioning ball 31 is separated from the positioning groove 32, allowing the plug 1 to be easily separated from the socket 2.

[0052] In some embodiments, the positioning hole 341 of the push block 34 and the positioning rod 35 need to have high positional accuracy. The positioning hole 341 on the push block 34 should not be misaligned with the positioning rod 35. Therefore, the cross-sectional shape of the push block 34 can be polygonal to prevent the push block 34 from rotating relative to the socket 2.

[0053] In some embodiments, the socket 2 is provided with a mounting hole 21 for mounting the positioning ball 31. A retaining ring is provided at one end of the mounting hole 21 near the positioning groove 32 to prevent the positioning ball 31 from dislodging from the mounting hole 21. The retaining ring and the socket 2 are an integral structure.

[0054] The retaining ring is used to limit the positioning ball 31 and prevent the positioning ball 31 from disengaging from the mounting hole 21. That is, the depth of the positioning groove 32 is less than the diameter of the positioning ball groove, and the positioning ball 31 is located within the positioning groove 32 with less than 1 / 2 of its volume.

[0055] In some embodiments, the push block 34 is slidably connected to the mounting hole 21, and the mounting hole 21 is also provided with a positioning post 37 for positioning the first elastic member 33. The push block 34 and the positioning ball 31 are in surface contact.

[0056] The push block 34 can be provided with a recess that contacts the positioning ball 31, so that the push block 34 and the positioning ball 31 can be in surface contact.

[0057] Reference Figures 1 to 7 As shown, in some embodiments, the positioning post 37 is threaded into the mounting hole 21, the mounting hole 21 is provided with an internal thread, the positioning post 37 is provided with an external thread that mates with the internal thread of the mounting hole 21, and the first elastic element 33 is located between the positioning post 37 and the push block 34.

[0058] The positioning post 37 is provided with an operating part, which is used to rotate the positioning post 37 to assemble or remove the positioning post 37. The operating part can be a prism-shaped protrusion or a prism-shaped groove, so that the operating part can be easily matched with a tool.

[0059] In some embodiments, the first elastic member 33 is a spring, the push block 34 is provided with a first guide post for guiding the first elastic member 33, a portion of the first elastic member 33 is sleeved on the first guide post, and the positioning post 37 is provided with a second guide post for guiding the first elastic member 33, a portion of the first elastic member 33 is sleeved on the second guide post.

[0060] In some embodiments, the first guide post and the push block 34 are integrally formed. The second guide post and the positioning post 37 are integrally formed. The diameter of the second guide post is smaller than the diameter of the positioning post 37. The second guide post and the positioning post 37 are coaxially arranged.

[0061] In some embodiments, the second elastic element 36 is a spring, one end of the second elastic element 36 is fixed to the positioning rod 35, and the other end of the second elastic element 36 is fixed to the plug 1.

[0062] In some embodiments, the positioning rod 35 is provided with a positioning shoulder, and one end of the second elastic member 36 is fixed to the positioning rod 35 via the positioning shoulder. The positioning shoulder can be fixed to the positioning rod 35 by threads. The positioning shoulder can also be an integral structure with the positioning rod 35.

[0063] Reference Figures 1 to 7 As shown, in some embodiments, the socket 2 is provided with a sliding hole 22 that cooperates with the positioning rod 35. The sliding hole 22 communicates with the mounting hole 21, and the sliding hole 22 passes through one end of the socket 2 near the plug 1.

[0064] In some embodiments, there are two positioning balls 31, which are located on both sides of the plug 1. The plug 1 is provided with two positioning grooves 32, each positioning groove 32 cooperating with an independent positioning ball 31. Each positioning ball 31 is pushed by an independent push block 34 and a first elastic member 33. Each first elastic member 33 is positioned by an independent positioning post 37. Furthermore, each push block 34 is positioned by an independent positioning rod 35, and each positioning rod 35 is provided with an independent second elastic member 36.

[0065] In some embodiments, the plug 1 is provided with a guide hole 11 for guiding the positioning rod 35. The guide hole 11 passes through the opposite ends of the plug 1, and the positioning rod 35 extends out of the end of the plug 1 away from the socket 2. A flexible connecting wire 38 is provided between the two guide rods to facilitate the operation of the positioning rod 35.

[0066] The flexible connecting wire 38 can be made of metal wire. Pulling the flexible connecting wire 38 can simultaneously disengage both positioning rods 35 from the positioning holes 341, making the positioning rods 35 easy to operate.

[0067] In practice, to prevent the fixed rod from malfunctioning, in some embodiments, the plug 1 is also provided with a locator 12 for positioning the positioning rod 35. The locator 12 is slidably connected to the plug 1, and the sliding direction of the locator 12 relative to the plug 1 is perpendicular to both the sliding direction of the push block 34 and the sliding direction of the positioning rod 35. The plug 1 is also provided with a retainer 13 for engaging the locator 12. The retainer 13 is provided with a slot 131 for positioning the locator 12, and the locator 12 is provided with a retaining block that cooperates with the slot 131.

[0068] After the positioner 12 is engaged, the end of the positioning rod 35 away from the socket 2 abuts against the positioner 12, thereby preventing the positioning rod 35 from malfunctioning. When it is necessary to disassemble the connector, first disengage the positioner 12 from the socket 13, and then pull the flexible connecting wire 38 to move the positioning rod 35.
