Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and in particular to an anti-detachment electrical connector. Background Technology

[0002] Electrical connectors are used to achieve electrical connections and signal transmission. They typically consist of two mating parts that enable electrical conduction. In applications such as automobiles, industrial equipment, and communication equipment, electrical connectors are often subjected to vibration, temperature changes, cable pulling, or repeated plugging and unplugging. The two mating parts are prone to loosening or even detachment, leading to problems such as poor contact, signal interruption, or power failure.

[0003] To improve connection reliability, existing technologies employ various anti-disengagement measures, such as threaded locking and locking sleeves. However, some existing anti-disengagement structures may still fail under prolonged use or when subjected to significant external forces due to insufficient structural strength, deformation under stress, or wear at the locking points, making it difficult to meet the requirements for connection stability under complex working conditions. Summary of the Invention

[0017] A further feature of the present invention is that a linear guide groove is provided on the mating surface of the first housing, and a linear guide rib is provided on the mating surface of the second housing, wherein the linear guide rib is engaged with the linear guide groove.

[0037] The invention will now be further described with reference to the accompanying drawings.

[0038] Example 1

[0039] A type of anti-disconnect electrical connector, such as Figures 1 to 6 As shown, it includes a male connector 1 and a female connector 2. The female connector 2 has a docking groove 201 with several docking holes 21. Each docking hole 21 has a socket 22. The male connector 1 has a plug 11 with pins 12 that correspond one-to-one with each socket 22. When the plug 11 is inserted into the docking groove 201, the pins 12 are engaged with the corresponding sockets 22, thereby achieving an electrical connection.

[0040] The female connector 2 is provided with a buckle plate 23, and a first buckle 231 is integrally formed on the buckle plate 23. The male connector 1 is provided with a first slot 13 corresponding to the position of the first buckle 231. When the plug 11 is inserted into the docking slot 201, the first buckle 231 engages with the first slot 13, thereby locking the male connector 1 and the female connector 2 to prevent them from accidentally disengaging due to vibration, pulling or collision. A reinforcing rib 232 is integrally formed on the end of the buckle plate 23 away from the first buckle 231. The reinforcing rib 232 extends along the insertion direction of the male connector 1 and the female connector 2 and extends to the bottom of the docking slot 201. The reinforcing rib 232 provides support to the end of the buckle plate 23 away from the first buckle 231, thereby enhancing the overall strength of the buckle plate 23 and preventing it from warping or deforming under repeated insertion and removal or external force. This also improves the reliability of the engagement between the first buckle 231 and the first slot 13. When unlocking is required, simply press the first buckle 231 to cause it to elastically deform and exit the first slot 13.

[0041] Furthermore, both the end of the female connector 2 furthest from the mating groove 201 and the end of the male connector 1 furthest from the plug 11 are provided with mounting grooves 100. A female splitter 32 is snapped into the mounting groove 100 of the female connector 2, and a male splitter 31 is snapped into the mounting groove 100 of the male connector 1. Both the female splitter 32 and the male splitter 31 are insulating components and can be made of insulating plastic. The female splitter 32 has several female split holes 321, and each socket 22 is respectively accommodated in the corresponding female split hole 321. The male splitter 31 has several male split holes 321. 11. Each pin 12 is accommodated in the corresponding male terminal branch hole 311. The female terminal branch hole 321 corresponds to the mating hole 21, and the male terminal branch hole 311 corresponds to the position of the plug 11. Both the female terminal splitter 32 and the male terminal splitter 31 are provided with a second latch 301. The mating female connector 2 and the mating male connector 1 are respectively provided with a second slot 302 corresponding to the position of the corresponding second latch 301. Each second latch 301 engages with the corresponding second slot 302, thereby fixing the female terminal splitter 32 to the mating female connector 2 and fixing the male terminal splitter 31 to the mating male connector 1. The female terminal splitter 32 and the male terminal splitter 31 can separate multiple wires 41, avoiding mutual interference or short circuits of the wires 41, and facilitating the positioning and installation of the socket 22 and the pin 12.

[0042] Furthermore, annular limiting grooves 303 are provided on the outer peripheral surfaces of both the sleeve 22 and the pin 12. Limiting blocks 304 protruding towards the axis of the corresponding branch holes are provided on the inner walls of both the female end branch hole 321 and the male end branch hole 311. The limiting blocks 304 extend into the corresponding annular limiting grooves 303 and engage with them, thereby axially limiting the sleeve 22 and the pin 12, preventing the sleeve 22 from dislodging from the female end branch hole 321 and the pin 12 from dislodging from the male end branch hole 311. During assembly, the annular limiting grooves 303 of the sleeve 22 or the pin 12 are aligned with and pressed against the limiting blocks 304, causing the limiting blocks 304 to elastically deform. When the annular limiting grooves 303 are fully inserted into the limiting blocks 304, the limiting blocks 304 spring back and engage with the annular limiting grooves 303.

[0043] Furthermore, this electrical connector also includes a conduit 4, through which a wire 41 is threaded; the conduit 4 is a metal conduit 4, preferably a flexible metal conduit, which can be used to thread and protect the wire 41; one end of the wire 41 extending out of the conduit 4 is fixedly connected to the socket 22, and the connection method is crimping; a sheath 5 is fixedly connected to the conduit 4, the sheath 5 is an insulating component, made of insulating plastic; the sheath 5 extends toward the mating female head 2, and covers the end of the mating female head 2 away from the mating groove 201 and the end of the conduit 4 close to the mating female head 2, thereby forming insulation protection for the connection of the wire 41. A snap-fit ​​block 24 is provided on the outer wall of the female connector 2. A fixing groove 243 is provided on the snap-fit ​​block 24. The fixing groove 243 divides the snap-fit ​​block 24 into a first snap-fit ​​block 241 and a second snap-fit ​​block 242 located on both sides of the fixing groove 243. A first snap-fit ​​strip 501 and a snap-fit ​​hole 502 adjacent to the first snap-fit ​​strip 501 are provided on the sheath 5. The second snap-fit ​​block 242 is snapped into the snap-fit ​​hole 502, and the first snap-fit ​​strip 501 is snapped into the fixing groove 243, so that the sheath 5 and the female connector 2 are reliably locked, preventing the sheath 5 from moving axially relative to the female connector 2 or from falling out.

[0044] Furthermore, the sheath 5 includes a first housing 51 and a second housing 52. The first housing 51 is provided with a third buckle 511, and the second housing 52 is provided with a third slot 521 corresponding to the position of the third buckle 511. The third buckle 511 and the third slot 521 engage, so that the first housing 51 and the second housing 52 are fastened together to form the sheath 5. This structure facilitates the assembly of the sheath 5 outside the conductor 41 and the conduit 4.

[0045] Furthermore, a linear guide groove 512 is formed on the mating surface of the first housing 51, and a linear guide rib 522 protrudes from the mating surface of the second housing 52, the linear guide rib 522 engaging with the linear guide groove 512. When the first housing 51 and the second housing 52 are fastened together, the linear guide rib 522 slides along the linear guide groove 512, serving as a guide and preventing misalignment, ensuring accurate alignment of the first housing 51 and the second housing 52, and improving the overall structural stability of the sheath 5.

[0046] Furthermore, a conductive sheet 53 is fixedly connected to the sheath 5, and the conductive sheet 53 abuts against the outside of the conduit 4; the conductive sheet 53 is made of conductive metal; a ground wire connection sleeve 54 is fixedly connected to the conductive sheet 53, and the ground wire connection sleeve 54 can be a conductive metal sleeve; a grounding wire is threaded through the mating female connector 2, and the grounding wire is electrically connected to the conductive sheet 53 through the ground wire connection sleeve 54. Since the conduit 4 is a metal conduit 4, especially when the conduit 4 is a flexible metal conduit used for power laying protection, it needs to be grounded nearby. In this embodiment, the conductive sheet 53 directly abuts against the outside of the metal conduit 4, and the grounding wire is electrically connected to the conductive sheet 53 through the ground wire connection sleeve 54, thereby reliably grounding the metal conduit 4. This structure eliminates the need for additional clamps or long exposed grounding wires on the flexible metal conduit, resulting in a short grounding path, low contact resistance, and high grounding reliability. This facilitates timely grounding in case of short circuits or other abnormal situations, improving safety.

[0047] Furthermore, the conductive sheet 53 has a sliding hole 531, and a bolt 532 passes through the sliding hole 531. The bolt 532 is threadedly connected to the sheath 5 to fix the conductive sheet 53 to the sheath 5. The sliding hole 531 is preferably an oblong hole or a waist-shaped hole. A threaded groove 42 is formed on the outer circumferential surface of the conduit 4. When the conduit 4 is a flexible metal tube, the threaded groove 42 can be a spiral groove on the outer circumference of the flexible metal tube. The conductive sheet 53 is provided with a second retaining strip 533 extending toward the threaded groove 42. The second retaining strip 533 is inclined, and its inclination direction is consistent with the spiral direction of the threaded groove 42. The position of the conductive sheet 53 relative to the bolt 532 can be adjusted through the sliding hole 531, so that the second retaining strip 533 is aligned and extends into the threaded groove 42. After the bolt 532 is tightened, the second retaining strip 533 engages with the threaded groove 42, which can be spirally matched according to the size of the conduit 4 and prevent the conduit 4 from rotating relative to the sheath 5 and being pulled out axially.

[0048] Furthermore, an insulating sheet 55 is provided at the outlet end of the conduit 4. The insulating sheet 55 is fixedly connected to the sheath 5 by a threaded connection. A cable management groove 551 is provided on the side of the insulating sheet 55 near the conductor 41, and the conductor 41 is fixed in the cable management groove 551. Multiple cable management grooves 551 can be provided, each corresponding to a conductor 41. After the conductor 41 is inserted into the cable management groove 551, it can be further fixed by means of adhesive, cable ties, etc. Fixing the conductor 41 to the sheath 5 by the insulating sheet 55 and the cable management groove 551 can prevent the conductor 41 from moving inside the sheath 5 and avoid the external pulling force being directly transmitted to the connection between the plug sleeve 22 and the conductor 41, thereby effectively preventing the wire from being pulled out.

[0049] Example 2

[0050] A non-detachable electrical connector, the difference between this embodiment and specific embodiment one is that: both the socket 22 and the pin 12 are formed with a shrinkage section 305, the cross-section of the shrinkage section 305 is hexagonal; the shrinkage section 305 can be used for crimping connection with the wire 41, taking the socket 22 as an example, such as Figure 7 As shown. During crimping, the end of the wire 41 is inserted into the tightening section 305 of the sleeve 22 or the pin 12, and then pressed by a hexagonal crimping die, so that the tightening section 305 forms a hexagonal cross section. This structure allows multiple contact surfaces to be formed between the wire 41 and the sleeve 22 or the pin 12, resulting in low contact resistance, high connection tensile force, and good pull-out resistance.

[0051] In Embodiments 1 and 2, conductive components such as the socket 22, pin 12, conductive sheet 53, and ground wire connection sleeve 54 can be made of conductive metal materials such as copper alloy, brass, and phosphor bronze; insulating components such as the sheath 5, female terminal splitter 32, and male terminal splitter 31 can be made of insulating plastic; and the conduit 4 is a flexible metal conduit. Preferably, the connection tensile force between each component is greater than 200N, and the connection tensile force between the flexible metal conduit and the electrical connector is greater than 1000N, thereby effectively reducing the risk of the wire being pulled out and improving the reliability of the electrical connector under vibration, tension, and other operating conditions.
