Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a self-locking connector. Background Technology

[0002] In the field of electronic device connectivity, connectors are key components for signal and power transmission, and their stability and protection performance directly affect the operation of the equipment.

[0003] In related technologies, connectors often only perform basic plugging and unplugging functions, lacking effective anti-loosening structures. Under conditions of vibration and tension, they are prone to loosening, leading to connection interruptions and affecting normal equipment operation. Furthermore, after the connector is plugged in, the first conductive terminal in the plug is inserted into the hole of the second conductive terminal in the socket. During use, gaps may occur between the first and second conductive terminals due to manufacturing tolerances, increasing contact resistance and potentially causing localized heating and arcing. In severe cases, this can burn out the socket or plug, or even cause a fire.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] In view of at least one of the above technical problems, this application provides a self-locking connector.

[0006] This application provides a self-locking connector, the connector comprising: The socket includes a first housing, a first conductive terminal, and a torsion spring. The first conductive terminal has multiple terminals and is disposed on the first housing. The first conductive terminal has a first socket along a first direction, and the torsion spring is located in the first socket. The plug includes a second housing and a second conductive terminal. The second conductive terminal has multiple terminals and corresponds one-to-one with the first conductive terminal. The second conductive terminal is disposed on the second housing and is configured to contact the narrowed end of the torsion spring when inserted into the first socket. The anti-reverse mechanism has a portion located on the first housing and another portion located on the second housing. The anti-reverse mechanism is configured to lock the first housing and the second housing when the socket and plug are plugged in.

[0007] This connector utilizes a torsion spring and a locking mechanism to ensure that the second conductive terminal is always in contact with the narrowed end of the torsion spring, thereby guaranteeing that the second conductive terminal is always electrically connected to the first conductive terminal. At the same time, the locking mechanism effectively prevents the first and second housings from detaching, solving the dual problems of loose contact and accidental detachment in traditional connectors and improving connection reliability.

[0009] In some possible implementations, the card block has a mating ramp and a stopping ramp spaced apart, the mating ramp facing the first housing and the stopping ramp facing the second housing, the stopping ramp being configured to abut against the bayonet.

[0010] In some possible implementations, the first housing includes a first connecting seat and a first insert, the first connecting seat having a first connecting cavity, the first insert having a plurality of inserts located in the first connecting cavity, and a first conductive terminal passing through the first insert; The second housing includes a second connector having multiple receiving cavities that mate with the first insert.

[0016] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0017] like Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the structure of the self-locking connector provided in the embodiments of this application. Figure 2 for Figure 1 A schematic diagram of the internal structure of the plug.

[0018] like Figure 1 and Figure 2 As shown, one embodiment provides a self-locking connector, which includes a socket 100, a plug 200, and a locking mechanism 300.

[0019] The socket 100 includes a first housing 110, a first conductive terminal 120, and a torsion spring 130. Multiple first conductive terminals 120 are located on the first housing 110, and each first conductive terminal 120 has a first socket 121 along a first direction. The torsion spring 130 is located within the first socket 121. The plug 200 includes a second housing 210 and a second conductive terminal 220. Multiple second conductive terminals 220 are located on the second housing 210 and are configured to contact the narrowed end of the torsion spring 130 when inserted into the first socket 121. A portion of the anti-retraction mechanism 300 is located on the first housing 110, and another portion is located on the second housing 210. The anti-retraction mechanism 300 is configured to lock the first housing 110 and the second housing 210 when the socket 100 and the plug 200 are plugged in.

[0020] It is understandable that the first direction corresponds to the front and back directions in the diagram, and the first direction is also the insertion and removal direction of the plug 200.

[0021] During the insertion process, the second conductive terminal 220 of the plug 200 is inserted into the first socket 121 of the socket 100 along the first direction. At this time, the second conductive terminal 220 contacts the narrowed end of the torsion spring 130. As the insertion depth increases, the torsion spring 130 is deformed by the compression of the second conductive terminal 220, and the deformation force helps to stabilize the second conductive terminal 220. At the same time, the two parts of the anti-retraction mechanism 300 gradually approach each other and trigger engagement during the insertion action. When the second conductive terminal 220 is fully inserted into the first socket 121, the anti-retraction mechanism 300 completes engagement, locking the first housing 110 and the second housing 210 to prevent the plug 200 from accidentally disengaging from the socket 100. At this time, the deformation force of the torsion spring 130 continues to act on the second conductive terminal 220 to ensure the contact stability between the conductive terminals.

[0022] In this embodiment, the connector utilizes the coordinated action of the torsion spring 130 and the anti-retraction mechanism 300 to ensure that the second conductive terminal 220 is always in contact with the narrowed end of the torsion spring 130, thereby guaranteeing that the second conductive terminal 220 is always electrically connected to the first conductive terminal 120. At the same time, the anti-retraction mechanism 300 can effectively prevent the first housing 110 and the second housing 210 from separating, solving the dual problems of loose contact and accidental detachment in traditional connectors and improving connection reliability.

[0023] like Figure 1 and Figure 2 As shown, in some embodiments, the anti-reverse mechanism 300 includes a plug-in seat 310, a guide member 320, and a locking block 330. The plug-in seat 310 is disposed on the first housing 110, and the plug-in seat 310 is provided with a guide groove 311 along a first direction. The plug-in seat 310 is provided with a locking slot 312 communicating with the guide groove 311. The guide member 320 is disposed on the second housing 210, and the locking block 330 is disposed at the end of the guide member 320. The locking block 330 is configured to engage with the locking slot 312.

[0024] During insertion, the plug 200 drives the guide member 320 into the guide groove 311 of the socket 310 along the first direction. The guide groove 311 positions and guides the guide member 320, preventing the plug 200 from shifting during insertion. As the guide member 320 goes deeper, the locking block 330 moves along the guide groove 311 with the guide member 320 until the locking block 330 reaches the locking position 312. When the locking block 330 moves to the locking position 312, it locks into the locking position 312 under its own elasticity. At this time, the first housing 110 and the second housing 210 are fixed and cannot be separated in the opposite direction. When unlocking, an external force needs to be applied to make the locking block 330 disengage from the locking position 312. After the locking block 330 exits the locking position 312, the guide member 320 can move out in the opposite direction along the guide groove 311, realizing the separation of the plug 200 and the socket 100.

[0025] like Figure 1 and Figure 2As shown, in some embodiments, the latch 330 has a mating ramp and a stopping ramp spaced apart. The mating ramp is positioned toward the first housing 110, and the stopping ramp is positioned toward the second housing 210. The stopping ramp is configured to abut against the latch 312.

[0026] The stop slope contacts the inner edge of the bayonet 312. Compared with a single plane or arc surface, it can withstand greater reverse pulling force, preventing the block 330 from detaching due to deformation under force, further enhancing the anti-detachment effect, and is suitable for harsh environments such as vibration and impact.

[0027] like Figure 1 and Figure 2 As shown, in some embodiments, the first housing 110 includes a first connecting seat 111 and a first insert 112. The first connecting seat 111 has a first connecting cavity 1111, and the first insert 112 has a plurality of inserts located in the first connecting cavity 1111. The first conductive terminal 120 passes through the first insert 112. The second housing 210 includes a second connecting seat 211, which has a plurality of receiving cavities 2111 that cooperate with the first insert 112. A portion of the second conductive terminal 220 is located in the receiving cavity 2111. A waterproof ring 212 is provided on the outer periphery of the second connecting seat 211, and the waterproof ring 212 is configured to contact the inner surface of the first connecting cavity 1111.

[0028] When plugged in, the first insert 112 is inserted into the receiving cavity 2111 to achieve precise docking between the housings, and at the same time, it drives the first and second conductive terminals 220 to make accurate contact.

[0029] A waterproof ring 212 is pre-installed on the outer periphery of the second connector 211. When the first insert 112 is inserted into the receiving cavity 2111 and the housing is docked, the waterproof ring 212 is squeezed between the outer periphery of the second connector 211 and the inner side of the first connecting cavity 1111 to form an annular sealing surface. After being squeezed, the waterproof ring 212 undergoes elastic deformation, filling the gap between the two and preventing external water, dust, oil and other impurities from entering the housing and protecting the conductive terminals from corrosion.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the outer peripheral surface of the waterproof ring 212 is provided with an annular protrusion.

[0031] The outer circumferential surface of the waterproof ring 212 is provided with annular protrusions. When the waterproof ring 212 is pressed between the second connecting seat 211 and the first connecting cavity 1111, the annular protrusions first contact the inner surface of the first connecting cavity 1111. As the insertion depth increases, the deformation of the annular protrusions under pressure is greater than that of other parts of the waterproof ring 212, forming multiple annular seals. Each annular protrusion fills the corresponding gap, and tiny air cavities are formed between the protrusions, further preventing impurities from entering.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the outer peripheral surface of the second connecting seat 211 is provided with an annular groove that mates with the waterproof ring 212. The annular groove provides a clear installation position for the waterproof ring 212, preventing the waterproof ring 212 from shifting or tilting during manual assembly, ensuring consistent sealing position for each product, and improving product quality stability.
