Description

Technical Field

[0001] This application relates to the field of electrical connection technology, and in particular to a connector with wiring stability. Background Technology

[0002] In the rapid iteration and continuous technological innovation of the new energy vehicle industry, the performance upgrade of core components has become a key driving force for industry progress. Connectors, as the core connection hub between the battery pack and the vehicle's electrical system, bear the important mission of power transmission and signal interaction. Their stability and reliability directly determine the vehicle's driving safety, range, and operational stability. With the increasing demand for high-power charging and long driving range in new energy vehicles, the operating environment of connectors is becoming increasingly complex, and the technical requirements for their structural design and resistance to loss are becoming increasingly stringent, making them a crucial link that urgently needs optimization in the process of industry upgrading. The mainstream connectors used in new energy vehicles mainly consist of a female socket installed under the vehicle and a male plug that adapts to the connection. The female socket has an internal cavity containing conductive pins for power conduction. The male plug has a corresponding mounting cavity on one side, housing conductive terminals that mate with the conductive pins. The other side has a mounting hole communicating with the mounting cavity, allowing the connecting cable to pass through and be secured to the conductive terminals. To ensure connection stability, the male plug has a spring-loaded retaining plate on its outer periphery. A lever is located on the side edge of the retaining plate near the mounting hole, and a hook protrudes from its outer surface. The inner wall of the female socket's receiving cavity has a corresponding slot. The hook can elastically engage with the slot for locking, and pressing the lever disengages the hook, completing the separation. In the aforementioned technologies, road bumps during vehicle operation generate continuous vibrations. These vibrations are transmitted through the vehicle body to the connection point between the connector and the connecting cable. This causes the connection between the cable and the inner wall of the mounting hole to be subjected to repeated friction and stress impacts from the vibrations over a long period. With prolonged use, this continuous mechanical action causes the outer insulation of the connecting cable to gradually wear and crack. In severe cases, it can even expose the internal conductors of the cable, potentially leading to short circuits, signal transmission interruptions, and other malfunctions. Furthermore, it directly threatens vehicle safety, indicating room for improvement. Summary of the Invention

[0003] The purpose of this application is to provide a connector with stable wiring, which solves the problem in the above-mentioned related technologies that the vibration of vehicle driving causes friction and wear at the connection between the connecting cable and the male plug, damages the insulation, and thus causes safety hazards.

[0004] The connector with improved wiring stability provided in this application adopts the following technical solution: A connector with stable wiring includes a female socket and a male plug that mates with the female socket. The female socket has a receiving cavity and a pin fixed within the receiving cavity. The male plug has a mounting cavity on one side and a terminal fixed within the mounting cavity. The other side of the male plug has a mounting hole communicating with the mounting cavity for cable insertion. A resilient locking plate is fixed to the outer periphery of the male plug, and a lever is fixed to the side edge of the resilient locking plate near the mounting hole. A hook is fixed to the outer surface of the resilient locking plate. A groove is formed on the inner wall of the receiving cavity for the hook to resiliently engage. An upper baffle near the lever and a lower baffle away from the lever are fixedly provided on the outer periphery of the plug facing the mounting hole. A connecting rod is rotatably connected to the lower baffle, and an adjusting plate is rotatably connected to the other end of the connecting rod. The adjusting plate can be rotated to a retracted state where it is in contact with the side of the male plug away from the lever, and to a limited state where it is in contact with the side of the male plug near the mounting hole. The male plug is provided with a locking member on the outside to limit the adjustment plate in the limited state. The adjusting plate has the same number of adjusting holes as the mounting holes. An elastic pad is fixed on the inner wall of the adjusting hole. When the adjusting plate is in the limited state, the adjusting hole is coaxial with the mounting hole.

[0005] By adopting the above technical solution, when the adjustment plate is switched to the limit position, the adjustment hole and the mounting hole are precisely coaxially aligned. The connecting cable passes through the adjustment hole and enters the mounting cavity. The elastic pad tightly presses against the outer circumference of the cable, which not only radially limits the cable and reduces the shaking amplitude caused by vibration, but also absorbs vibration energy through elastic buffering, avoiding direct friction between the cable and the inner wall of the mounting hole. This significantly reduces the risk of insulation wear and cracking, ensuring circuit conductivity stability and driving safety. At the same time, the adjustment plate can be flexibly switched to the storage position, achieving the dual functions of limit and storage with the locking mechanism. This does not affect the convenience of connector insertion and removal, and also reduces volume and cost during transportation.

[0006] Optionally, the locking component includes a locking rod located outside the elastic plate, with extension rods vertically fixed at both ends of the locking rod. A sliding block is rotatably mounted on the side of the extension rod away from the locking rod, and the sliding block is slidably mounted on the side of the male plug facing the lever. The locking rod can reciprocate and be fixed in the direction close to the lever. A protruding plate is fixed on the side of the adjusting plate away from the connecting rod, and a clearance notch is opened on the side of the upper baffle. When the adjusting plate is in the limited state, a locking slot is opened on the side of the protruding plate facing the male plug. A locking insert is fixed on the extension rod, and the locking insert can be engaged into the locking slot as the sliding block slides when the adjusting plate is in the limited state.

[0007] By adopting the above technical solution, when the sliding block drives the locking rod to slide, the locking plug on the extension rod can accurately engage with the locking slot on the protruding plate, quickly completing the positioning of the adjustment plate and ensuring that the adjustment hole and the mounting hole are always coaxially aligned, thus guaranteeing the cable limiting effect. Simultaneously, the locking rod, located outside the elastic plate, forms a physical protective barrier, preventing accidental triggering of the elastic plate due to unrelated contact or impact from gravel, and preventing accidental disconnection of the male and female plugs. The sliding engagement design between the sliding block and the male plug makes the locking operation flexible and convenient, without affecting connector insertion and removal maintenance. This improves the reliability of cable fixing and enhances the overall protective and stable performance of the connector structure.

[0008] Optionally, a first inclined surface is provided at the outer periphery of the locking block, and a second inclined surface is provided at the opening edge of the locking slot.

[0009] By adopting the above technical solution, the first inclined surface and the second inclined surface form a guiding fit, which can guide the locking block to quickly and accurately snap into the locking slot, simplify the locking operation of the adjustment plate, and at the same time buffer the impact force of the snap-fit, improving the convenience of locking and the durability of the structure.

[0010] Optionally, the male plug is provided with a limiting rod on its exterior, and fixed rods are vertically fixed at both ends of the limiting rod. Limiting notches for the limiting rod to slide into are provided on the opposite sides of the upper and lower baffles. Limiting slots are provided on the opposite sides of the two extension rods. When the fixed rod is in the limiting notch and the locking block is engaged in the locking slot, the end of the fixed rod away from the limiting rod can be inserted into the limiting slot.

[0011] By adopting the above technical solution, after the locking plug is engaged in the locking slot to complete the first-level locking, the fixing rod slides into the limiting notches of the upper and lower baffles and inserts into the limiting slot of the extension rod, forming a double limiting on the extension rod and the locking rod. This effectively prevents the locking plug from loosening due to vehicle vibration, ensuring that the adjusting plate always remains in the limited state and guaranteeing the cable limiting effect. At the same time, the setting of the limiting rod does not affect the normal operation of the locking rod and the adjusting plate, and can enhance the impact resistance of the overall structure, preventing the locking structure from failing under external force, further improving the reliability of the connector in complex road conditions, and ensuring the stable and safe transmission of power and signals.

[0012] Optionally, a third inclined surface is provided at the outer edge of the end of the fixing rod away from the limiting rod.

[0013] By adopting the above technical solution, the third inclined surface plays a guiding role, which can guide the fixing rod to slide smoothly into the limiting notch and accurately insert into the limiting slot, simplifying the secondary locking operation process, while buffering the impact force during insertion, improving the ease of assembly and structural durability.

[0014] Optionally, the locking lever can be rotated away from the lever to a retracted state that fits against the side of the male plug facing the lever. When the locking lever is in the retracted state, a first slot is provided on the side away from the upper baffle. When the adjusting plate is in the retracted state, a second slot is provided on the side away from the lower baffle. When both the adjusting plate and the locking lever are in the retracted state, the two fixing rods can slide out from the limiting notch, and the two fixing rods can be inserted into the first slot and the second slot respectively.

[0015] By adopting the above technical solution, the locking rod and adjusting plate are retractably and collaboratively fixed. When both are switched to the retracted state, the fixing rod is removed from the limiting notch and inserted into the first and second slots respectively, which can stably limit the retracted form, effectively reducing the overall volume of the male plug and reducing the space occupation and cost of transportation and storage. At the same time, this retractable structure requires no additional tools, is easy to operate, and does not damage the structural integrity of each component; after retraction, each component fits against the surface of the male plug, avoiding structural damage caused by shaking or bumping during transportation, further improving the safety and economy of product turnover, and adapting to the actual needs of large-scale production and transportation.

[0016] Optionally, a fourth bevel is provided at the opening edge of both the first slot and the second slot.

[0017] By adopting the above technical solution, the fourth inclined surface can form a guiding function, guiding the fixing rod to be quickly and accurately inserted into the first slot and the second slot, simplifying the locking operation in the storage state, while buffering the insertion impact force, improving assembly efficiency and structural durability.

[0018] Optionally, the cross-section of the sliding block is dovetail-shaped, and the male plug has a dovetail groove on the side facing the dial block that slides with the sliding block.

[0019] By adopting the above technical solution, the dovetail-shaped sliding block and the dovetail groove form a precise sliding fit, which can limit the radial displacement of the sliding block, avoid loosening or jamming during sliding, and ensure the stability and smoothness of the locking lever sliding adjustment. At the same time, the high fit of the dovetail structure can distribute the force during sliding, improve the structural strength and durability of the sliding component, ensure that the locking insert can be accurately aligned with the locking slot, and maintain the reliability of the locking state of the adjustment plate.

[0020] Optionally, the bottom surface of the sliding block is provided with an elastic snap-fit ​​component, and the inner wall of the dovetail groove is provided with several positioning grooves.

[0021] By adopting the above technical solution, when the sliding block moves to the target position, the elastic locking component engages with the corresponding positioning groove, preventing the sliding block from shifting due to vehicle vibration and ensuring that the locking block stably engages with the locking slot. At the same time, this structure requires no additional fasteners, is easy to operate, and improves the reliability and durability of the locking structure.

[0022] Optionally, the elastic snap-fit ​​component includes a compression spring and an arc-shaped protrusion. The sliding block has a placement groove for the compression spring and the arc-shaped protrusion to be placed in. The compression spring squeezes one side of the arc-shaped protrusion, causing a part of the arc-shaped protrusion to protrude from the opening of the placement groove. The outer surface of the protruding part of the arc-shaped protrusion is an arc surface, and the arc length corresponding to this arc surface is a minor arc.

[0023] By adopting the above technical solution, the compression spring provides continuous elastic pressure to the arc-shaped protrusion, ensuring that its protruding part is stably engaged in the positioning groove, thus guaranteeing the reliability of the sliding block's position locking. The inferior arc surface design of the arc-shaped protrusion allows the protrusion to retract when the sliding block is under force, without the need for additional unlocking operations. This achieves smooth displacement and precise positioning of the sliding block, improving the ease of operation and durability of the locking structure.

[0024] In summary, this application includes the following beneficial technical effects: In this application, when the adjustment plate is switched to the limit position, the adjustment hole and the mounting hole are precisely coaxially aligned. The connecting cable passes through the adjustment hole and enters the mounting cavity. The elastic pad tightly presses against the outer periphery of the cable, which can not only limit the cable radially and reduce the shaking amplitude caused by vibration, but also absorb vibration energy through elastic buffering, avoid direct friction between the cable and the inner wall of the mounting hole, significantly reduce the risk of insulation wear and cracking, and ensure the stability of circuit conduction and driving safety.

Detailed Implementation

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A connector with wiring stability includes a female socket 1 and a male plug 2 that is plugged into the female socket 1. The female socket 1 has a receiving cavity 11 and a pin 12 fixed in the receiving cavity 11. One side of the male plug 2 has a mounting cavity 21 and a terminal (not shown in the figure) fixed in the mounting cavity 21. The other side of the male plug 2 has a mounting hole 22 that communicates with the mounting cavity 21 and allows a connecting cable to be inserted. The male plug 2 is fixed with an elastic locking plate 23 that can be pressed elastically. A lever 231 is fixed on the side edge of the elastic locking plate 23 near the mounting hole 22. A hook 232 is fixed on the outer side of the elastic locking plate 23. A slot 13 is opened on the inner wall of the receiving cavity 11 for the hook 232 to be elastically engaged. An upper baffle 24 near the lever 231 and a lower baffle 25 away from the lever 231 are fixed on the outer periphery of the male plug 2 facing the mounting hole 22.

[0029] The implementation principle of this application embodiment is as follows: In the plug-in fixed state: align the male plug 2 with the receiving cavity 11 of the female socket 1 and insert it. The conductive terminals and pins 12 are precisely aligned. The connecting cable is connected to the mounting cavity 21 through the mounting hole 22 and fixed. The hook 232 of the elastic locking plate 23 elastically engages with the slot 13, achieving a stable lock between the male plug 2 and the female socket 1, ensuring the basic stability of power and signal transmission.

[0030] Separation / Disassembly State: Pressing the lever 231 drives the elastic plate 23 to deform, causing the hook 232 to disengage from the slot 13, which can easily separate the male plug 2 from the female socket 1, completing cable disassembly or connector maintenance. The operation is convenient and does not affect the structural integrity.

[0031] Example 2: Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that the male plug 2 is provided with an adjustment component 3 on its outside. The adjustment component 3 includes a connecting rod 31 rotatably connected to the lower baffle 25, and the other end of the connecting rod 31 is rotatably connected to the adjustment plate 32. The adjusting plate 32 can be rotated to a retracted state where it is in contact with the side of the male plug 2 away from the lever 231, and to a limited state where it is in contact with the side of the male plug 2 near the mounting hole 22. The male plug 2 is provided with a locking member 4 on the outside to limit the adjusting plate 32 in the limited state. The adjusting plate 32 has the same number of adjusting holes 321 as the mounting holes 22. The inner wall of the adjusting hole 321 is fixed with an elastic pad 322 made of rubber. When assembling the male plug 2 and the connecting cable, adjust the adjusting plate 32 to the limit position and lock it with the locking piece 4. At this time, the adjusting hole 321 is coaxial with the mounting hole 22. Then, the connecting cable is inserted into the mounting hole 22 after passing through the adjusting hole 321. The elastic pad 322 is used to press against the outer circumference of the connecting cable.

[0032] Reference Figure 6 and Figure 7 The locking member 4 includes a locking rod 41 located outside the elastic plate 23. The two ends of the locking rod 41 are vertically fixed with extension rods 42, and the locking rod 41 and the extension rods 42 are offset. A sliding block 43 is rotatably mounted on the side of the extension rod 42 away from the locking rod 41. The sliding block 43 is slidably mounted on the side of the male plug 2 facing the dial 231. The locking rod 41 can slide back and forth and be fixed in the direction close to the dial 231. A locking insert 44 is fixed on the side of the extension rod 42 facing the upper baffle 24. A first inclined surface 441 is provided at the outer periphery of the locking insert 44. The adjusting plate 32 has an integrally formed protruding plate 33 on the side away from the connecting rod 31. The upper baffle 24 has a clearance notch 241 on the side. When the adjusting plate 32 is in the limited position, the protruding plate 33 has a locking slot 331 on the side facing the male plug 2. The locking slot 331 has a second inclined surface 332 at the opening edge. When the adjusting plate 32 is in the limited position, the locking block 44 can be engaged into the locking slot 331 as the sliding block 43 slides, thereby limiting and locking the adjusting plate 32 in this state. At this time, the locking rod 41 can protect the outside of the elastic plate 23, reducing the possibility of the male plug 2 and the female socket 1 being disconnected due to impacts from unauthorized persons or road debris on the elastic plate 23.

[0033] Reference Figure 8 The cross-section of the sliding block 43 is dovetail-shaped. The male plug 2 has a dovetail groove 26 on the side facing the dial block 231 that slides with the sliding block 43. The bottom surface of the sliding block 43 is provided with an elastic snap-fit ​​45, and the inner wall of the dovetail groove 26 is provided with several positioning grooves 261. The elastic snap-fit ​​component 45 includes a compression spring 451 and an arc-shaped protrusion 452. The sliding block 43 has a placement groove 431 for the compression spring 451 and the arc-shaped protrusion 452 to be placed. The compression spring 451 presses one side of the arc-shaped protrusion 452 so that a part of the arc-shaped protrusion 452 protrudes from the opening of the placement groove 431. The outer surface of the protruding part of the arc-shaped protrusion 452 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. When the sliding block 43 slides to a certain position, under the action of the compression spring 451, the protruding part of the arc-shaped protrusion 452 is engaged into the positioning groove 261 at the corresponding position, thereby limiting the sliding of the sliding block 43 at this position.

[0034] Reference Figure 8 , Figure 9 and Figure 10 The male plug 2 is provided with a limiting component 5 on its outside. The limiting component 5 includes a limiting rod 51 and a fixing rod 52 vertically fixed at both ends of the limiting rod 51. A third inclined surface 521 is provided at the outer edge of the end of the fixing rod 52 away from the limiting rod 51. A limiting notch 242 for the limiting rod 51 to slide into is provided on the side of the upper baffle 24 and the lower baffle 25 that are far apart from each other. A limiting slot 421 is provided on the side of the two extension rods 42 that are far apart from each other. When the fixing rod 52 is slidably placed inside the limiting notch 242 and the locking block 44 is engaged in the locking slot 331, the end of the fixing rod 52 away from the limiting rod 51 can be inserted into the limiting slot 421 along the third inclined surface 521, thereby further limiting and locking the extension rod 42 and the locking rod 41 in this state, and improving the corresponding assembly stability.

[0035] Reference Figure 11 , Figure 12 and Figure 13 The locking lever 41 can be rotated in a direction away from the lever 231 to a retracted state that is in contact with the side of the male plug 2 facing the lever 231. When the locking lever 41 is in the retracted state, a first slot 411 is provided on the side away from the upper baffle 24. When the adjusting plate 32 is in the retracted state, a second slot 333 is provided on the side away from the lower baffle 25. A fourth inclined surface 412 is provided at the opening edge of both the first slot 411 and the second slot 333. When the male plug 2 is packaged separately for transport, the adjusting plate 32 and the locking rod 41 are both adjusted to the retracted state. Then, the staff can slide the two fixing rods 52 out of the limiting notch 242 and insert the two fixing rods 52 into the first slot 411 and the second slot 333 respectively. In this way, the limiting rod 51 and the two fixing rods 52 are used to limit and lock the retracted state of the adjusting plate 32 and the locking rod 41, thereby reducing the size of the male plug 2 during transportation and reducing transportation costs.

[0036] The implementation principle of this application embodiment is as follows: Assembly Limiting State: Rotate the adjusting plate 32 to the limiting state where it abuts against the mounting hole 22 of the male plug 2. Slide the locking rod 41 so that the locking block 44 is inserted into the locking slot 331 of the adjusting plate 32 along the inclined surface. The fixing rod 52 slides into the limiting notch 242 and inserts into the limiting slot 421 of the extension rod 42, thus doubly locking the adjusting plate 32. The connecting cable is connected to the mounting hole 22 through the adjusting hole 321 (elastic pad 322 abuts against the outer periphery), achieving precise positioning and fixation of the cable.

[0037] Storage and transportation state: Turn the adjustment plate 32 and locking rod 41 to the storage state, then take out the limiting rod 51, and insert the two fixing rods 52 on the same locking rod 41 into the first slot 411 and the second slot 333 respectively to lock the adjustment plate 32 and locking rod 41 in the storage state, reducing volume and transportation costs.

[0038] Separation / Disassembly State: Pressing the lever 231 drives the elastic plate 23 to deform, causing the hook 232 to disengage from the slot 13, which can easily separate the male plug 2 from the female socket 1, completing cable disassembly or connector maintenance. The operation is convenient and does not affect the structural integrity.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
