Detailed implementation manners

[0019] The following description provides specific application scenarios and requirements of this specification, aiming to enable those skilled in the art to manufacture and use the content in this specification. For those skilled in the art, various local modifications to the disclosed embodiments are obvious, and the general principles defined here can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the shown embodiments, but has the broadest scope consistent with the claims.

[0020] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "longitudinal", "lateral", "radial", "length", "width", "thickness", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0021] Secondly, the terms "first", "second" and similar words do not represent any order, quantity or importance, but are only used to distinguish different components, and should not be understood as a limitation to the embodiments of this application.

[0022] In addition, the terms "installed", "set", "provided with", "connected", "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, elements or components.

[0023] For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] Regarding the drawings of this application, it should be clearly understood that the drawings are only for the purpose of illustration and description, and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0025] AsFigures 1 to 3 As shown, this specification provides a connector, which includes a male plug 1 and a female plug 2. The male plug 1 includes a plug block portion 100, and the female plug 2 includes a socket portion 200. A plurality of wiring terminals 3 are arranged on the plug block portion 100, and a plurality of pins 4 and at least one ground pin 5 are arranged in the socket portion 200, realizing the grounding function of the connector. When the plug block portion 100 is inserted into the socket portion 200, the pins 4 and the wiring terminals 3 are connected. The length of the ground pin 5 is greater than the length of the pin 4. After the ground pin 5 and the corresponding wiring terminal 3 are connected, they are used for grounding. The lengthened ground pin 5 can prevent risks of static electricity, surges and leakage, ensure that the system is stably grounded before power / signal transmission, and avoid logic errors or component damage. Especially during the commissioning stage and hot plugging of electrical equipment, the safety is greatly improved.

[0026] Secondly, a partition board 6 is arranged in the socket portion 200. The partition board 6 isolates the ground pin 5 and the pins 4. As Figure 2 shown, the ground pin 5 is arranged at the lower left corner of the socket portion 200, and the L-shaped partition board 6 isolates it from other pins 4, which can improve the withstand voltage level of the product, reduce the risks of arc discharge and breakdown, reduce the electromagnetic interference crosstalk between adjacent pins, and reduce electrostatic discharge. This is mainly because the arrangement of the partition board 6 increases the creepage distance of the arc.

[0027] The partition board 6 is asymmetrically arranged in the socket portion 200, and a slot 101 for the partition board 6 to insert is arranged on the plug block portion 100, so as to play an anti-misinsertion function between the male plug 1 and the female plug 2.

[0028] Exemplarily, as Figure 2 shown, one ground pin 5 is arranged in the socket portion 200, and the L-shaped partition board 6 isolates it from other pins 4.

[0029] Exemplarily, as Figure 14 shown, a row of ground pins 5 is arranged in the socket portion 200, and the -shaped partition board 6 isolates it from other pins 4.

[0030] Since the traditional male plug and female plug may be in a semi-plugged state during plugging, that is, although they are connected, the connection is unreliable.

[0031] In some embodiments, as Figures 4 to 16As shown, based on the above-mentioned connector, a socket 7 is provided on the plug block portion 100, and a gear mechanism 8 is provided between the plug block portion 100 and the socket 7. The gear mechanism 8 enables the socket 7 to have a pre-installed position and a connection position when sleeved on the plug block portion 100. When the socket 7 is in the pre-installed position, the male plug 1 and the female plug 2 cannot be connected. When the socket 7 is in the connection position, the male plug 1 and the female plug 2 are plugged in place and connected. When the plug block portion 100 and the socket portion 200 are plugged together, the socket 7 can be pushed from the pre-installed position to the connection position. With such a setting, when the connector is shipped from the factory, the socket 7 is assembled in the pre-installed position. When the user uses it, due to the setting of the gear mechanism 8, there are only the connected state and the disconnected state. Only when the socket 7 is first pushed to the connection position can the male plug 1 and the female plug 2 be plugged in place and connected, otherwise it is in the disconnected state, greatly improving the safety and reliability of the connector.

[0032] Specifically, the gear mechanism 8 includes two gear slots 800 and a gear convex block 801. One is provided on the plug block portion 100, and the other is provided on the socket 7. Moving guide surfaces 802 are provided on the front and rear sides of the gear slot 800 and the gear convex block 801. The front and rear sides are understood as the two sides in the plugging direction of the male plug 1 and the female plug 2. The moving guide surfaces 802 help the gear convex block 801 to move and switch between the two gear slots 800, and it can be an inclined surface, an arc surface, or a combination of an inclined surface and an arc surface.

[0033] As Figure 4 and Figure 5 As shown, two gear slots 800 are provided at the bottoms on both sides of the plug block portion 100, and the gear slots 800 are grooves with a trapezoidal cross-section. Gear convex blocks 801 are provided on both sides of the inner bottom wall of the socket 7, and the gear convex blocks 801 are convex blocks with a trapezoidal cross-section. Since the material used for this connector is generally plastic and has a certain elasticity, the two-gear function can be achieved through two gear slots 800 and one gear convex block 801. It should be understood that in addition to the trapezoid, shapes such as triangles and semi-circles can also achieve the gear function.

[0034] In some embodiments, an installation channel 101 is provided on the male plug 1. The wiring terminal 3 is disposed at the front end of the installation channel 101. A butt joint portion 300 is provided on the wiring terminal 3. A limiting block is provided at the front end of the installation channel 101. An elastic arm 102 is provided on the male plug 1 facing the front end of the installation channel 101. A positioning convex block portion 103 is provided at the front end of the elastic arm 102 facing the wiring terminal 3. When the socket 7 is sleeved on the plug portion 100, the positioning convex block portion 103 is pressed against the wiring terminal 3. During assembly, the wiring terminal 3 only needs to be inserted from the rear end of the installation channel 101. The wiring terminal 3 will push up the elastic arm 102 through the positioning convex block portion 103. When it is inserted in place, that is, when the front end of the wiring terminal 3 abuts against the limiting block, the elastic arm 102 drops so that the positioning convex block portion 103 abuts against the butt joint portion 300, fixing the wiring terminal 3 in the installation channel 101. Thus, the assembly process of the wiring terminal 3 is simplified and no additional fasteners are required.

[0035] It can be understood that the front end of the male plug 1 is the end close to the female plug 2.

[0036] In addition, since when the socket 7 is sleeved on the plug portion 100, the positioning convex block portion 103 is pressed against the wiring terminal 3, the wiring terminal 3 is firmly fixed in the installation channel 101, greatly improving the stability and reliability of the connection of the connector.

[0037] Among them, as Figures 6 to 8 shown, a first inclined surface 104 is provided on the elastic arm 102. It is located on the end surface of the elastic arm 102 facing away from the wiring terminal 3 and gradually inclines from the front end of the installation channel 101 towards the wiring terminal 3. A second inclined surface 700 with the same slope as the first inclined surface 104 is provided on the inner wall of the socket 7. Thus, when the socket 7 is sleeved on the plug portion 100, it is more smooth. Under the cooperation and guidance of the first inclined surface 104 and the second inclined surface 700, the elastic arm 102 quickly presses down to fix the wiring terminal 3.

[0038] Furthermore, the rear end of the positioning convex block portion 103 is provided as a smooth guiding surface 105. With such a setting, it is easier for the wiring terminal 3 to push up the elastic arm 102 when inserted into the installation channel 101.

[0039] Furthermore, as Figure 7As shown, a third inclined surface 106 is provided at the front end of the positioning bump portion 103. The third inclined surface 106 inclines towards the front end of the installation channel 101 on the side close to the terminal 3. The third inclined surface 106 abuts against the abutting portion 300, and a cavity is formed below the abutting portion 300, or the abutting portion 300 is an abutting inclined surface with the same slope as the third inclined surface 106. With such a setting, under the pressing of the socket 7, the lower side of the third inclined surface 106 extends into the cavity below the abutting portion 300, which is more firm and reliable compared with the abutting of two flat surfaces.

[0040] In some embodiments, a sealing sleeve 9 is sleeved on the plug portion 100. The sealing sleeve 9 is located behind the socket 7. When the socket 7 is in the connected position, the socket 7 abuts against the sealing sleeve 9, and the sealing sleeve 9 is pressed between the plug portion 100 and the socket portion 200. With such a setting, the connector has the functions of waterproofing and dustproofing. Secondly, when the plug and socket connector leaves the factory, the socket 7 is assembled at the pre-installed position, which can avoid the loss of the sealing sleeve during the circulation process.

[0041] Further, at least two or more annular ribs are provided on the outer wall of the sealing sleeve 9 to form a better seal between the plug portion 100 and the socket portion 200.

[0042] As Figure 9 shown, an insertion interface 301 that cooperates with the plug pin is provided at the front end of the terminal 3, and a wiring port 302 is provided at the rear end thereof.

[0043] The traditional male plug and female plug are fixed after being inserted in place through a snap connection, but the current snap connection structure cannot meet the requirements of firmness, convenience, detachability, and service life.

[0044] In some embodiments, for the male plug 1 and the female plug 2, a first connection portion is provided on one of them, and a second connection portion is provided on the other. The first connection portion includes two side plates 10 and a rocker 11 located between the two side plates 10. A bayonet portion 12 is provided at the front end of the rocker 11, an opening portion 13 is provided at the rear end thereof, and a fulcrum block 14 is provided in the middle thereof. Or, as Figure 15As shown, there are two fulcrum blocks 402, which are symmetrically arranged on both sides of the middle part of the rocker 11. The rocker 11 can elastically deform relative to the two side plates 10. The second connecting part is a clamping block 15 adapted to the bayonet part 12. When the male plug 1 and the female plug 2 are plugged in place, the clamping block 15 is clamped in the bayonet part 12. With such a setting, a lever-type clamping structure is adopted. Just press the opening part 13, and the rocker 11 can use the fulcrum block 14 as a fulcrum to make the bayonet part 12 tilt and disengage from the clamping block 15. In this way, the force required for unlocking can be reduced, facilitating the quick disassembly and assembly of the male plug and the female plug. At the same time, the service life of the connector can be greatly extended, and the connection firmness and reliability between the male plug and the female plug can be ensured.

[0045] If the lever-type structure is not adopted, that is, the fulcrum block 15 is not provided, then when the opening part 13 is pressed, greater deformation will occur on both sides of the rocker 11, and there is no assistance from the fulcrum block 15 when restoring the deformation, resulting in the structure being prone to elastic fatigue and ultimately unable to form a reliable clamping connection with the clamping block 15 due to elastic failure.

[0046] In this specification, an example is given where the first connecting part is arranged on the male plug 1 and the second connecting part is arranged on the female plug 2.

[0047] In some embodiments, a guiding surface 16 is arranged on the side of the clamping block 15 facing the rocker 11, and a guiding surface 17 cooperating with the guiding surface 16 is arranged on the side of the rocker 11 facing the clamping block 15. Both the guiding surface 16 and the guiding surface 17 can adopt an inclined surface and / or an arc surface. When the male plug 1 and the female plug 2 are plugged in, under the cooperation of the guiding surface 16 and the guiding surface 17, the clamping block 15 can be smoothly and quickly inserted into the bayonet part 12.

[0048] A first abutting inclined surface 18 is arranged on the side of the clamping block 15 facing away from the rocker 11. The lower side of the first abutting inclined surface 18 is inclined towards the rocker 11. The bayonet part 12 includes a second abutting inclined surface 19 with the same slope as the first abutting inclined surface 18. With such a setting, compared with the structure formed by two vertical surfaces for abutting, it has better clamping strength.

[0049] Among them, the inclination angle B between the first abutting inclined surface 18 and the second abutting inclined surface 19 relative to the lower end surface of the clamping block 15 is 75° - 85°. This inclination angle range is just right to ensure that the clamping block 15 can be inserted into the bayonet part 12 while ensuring the clamping strength.

[0050] In some embodiments, protective plates 20 extend from the upper ends of the two side plates 10 towards the center of the rocker 11. A gap 21 is provided between the two protective plates 20, and the width of the gap 21 is smaller than the width of the rocker 11. In the traditional structure, either the protective plates 20 are not provided, or the protective plates 20 are provided but the two protective plates are integrally connected. In this way, the protective plates 20 are extremely easy to be damaged during the circulation process. On the contrary, by adopting this split structure, the overall impact resistance is enhanced, and damage during the circulation process is avoided.

[0051] As Figure 11 shown, the opening part 13 protrudes upward relative to the rocker 11, and a pressing inclined surface 30 is provided on the side facing away from or facing the bayonet part 12, so as to facilitate operating the opening part 13 to make the bayonet part 12 tilt up and disengage from the latch 15. In the appendix Figure 11 the pressing inclined surface 30 is provided on the side facing away from the bayonet part 12.

[0052] In some embodiments, a locking member 22 is further included. The rocker 11 includes connecting plate portions 23 extending backward from both sides of its front end. The rear sides of the connecting plate portions 23 are connected to the side plates 10. The two connecting plate portions 23 and the two side plates 10 form a locking hole 24. The locking member 22 includes a top plate portion 25 and an insertion plate portion 26. A first card slot 27 and a second card slot 28 are provided on the insertion plate portion 26. Specifically, as Figure 13 shown, two spacer blocks are provided at intervals along the insertion direction on both sides of the insertion plate portion 26. The two sides of the spacer blocks are provided as inclined surfaces or arc surfaces or a combination of inclined surfaces and arc surfaces. In this way, a first card slot 27 is formed between the two spacer blocks, and a second card slot 28 is formed between one spacer block and the top plate portion 25. A locking block 29 is provided on the connecting plate portion 23 facing the insertion plate portion 26. When the locking block 29 cooperates with the first card slot 27, the top plate portion 25 is located outside the locking hole 24. When the locking block 29 cooperates with the second card slot 28, the top plate portion 25 blocks the downward pressing of the opening part 13. Generally, when the connector leaves the factory, the locking block 29 is in the first card slot 27. At this time, the male plug 1 and the female plug 2 can be normally inserted. After the male plug 1 and the female plug 2 are inserted in place, the locking member 22 is further pushed into the locking hole 24, and the locking block 29 moves into the second card slot 28. At this time, the top plate portion 25 also moves below the opening part 13, blocking the downward pressing of the opening part 13, which can play an insurance role.
