Abstract

The present invention discloses a coupler with waterproof function, comprising a plug and a socket, wherein the plug is provided with a plug pin and a driving rod, and the socket is provided with a plug interface, a waterproof component, a driving hole and a driving slider. When the socket is not plugged with the plug, the waterproof component blocks the plug interface. Only when the plug is inserted into the socket, the driving rod passes through the driving hole to push the driving slider, so that the driving slider drives the waterproof component to release the shielding of the plug interface through a guide structure. By adopting this technical solution, the structural setting of the original waterproof rubber pad is cancelled, and the problem of water entering the socket due to aging and cracking of the waterproof rubber pad is avoided. According to the transmission cooperation between the driving rod, the driving slider and the waterproof component, it is ensured that the waterproof component opens the plug interface when the plug and the socket are plugged together, and closes the plug interface when the plug and the socket are separated. The waterproof component designed in this way will not affect the normal insertion of the plug pin, and can prevent external moisture from flowing into the socket, thereby improving the safety and reliability of the coupler when used outdoors.

When the drive slider moves upward along the guiding chute, it slides and pushes the right guiding inclined plate through the upper driving inclined surface to push the waterproof component to move from the open position to the closed position.

[0010] In the above-described coupler with a waterproof function, the two limiting plates extend a set distance along the length direction of the socket.

The left guiding inclined plate and the right guiding inclined plate are respectively slidably connected in the two strip-shaped limiting grooves.

[0011] In the above-described coupler with a waterproof function, the drive slider includes a circular sliding column slidably connected in the circular through groove in a matching manner, and the lower driving inclined surface and the upper driving inclined surface formed on both sides of the circular sliding column and respectively extending through the two strip-shaped limiting grooves.

[0013] In the above coupler with a waterproof function, a raised end suitable for insertion into the driving hole and flush with the top surface of the socket is provided at the top of the circular sliding column, and a sealing ring is provided between the raised end and the driving hole.

[0014] In the above coupler with a waterproof function, a plurality of sealing gaskets corresponding to the top of the sliding baffle and located on one side of a plurality of the jacks are provided, and the plurality of sealing gaskets respectively block the plurality of plug interfaces when the waterproof component is in the closed position.

[0019] In the above coupler with a waterproof function, at least one sliding rib extending along the length direction of the socket is provided at the bottom of the sliding baffle, and a plurality of limiting ribs intersecting with the sliding rib are arranged at intervals on the top of the base along the extending direction of the sliding rib, and the sliding baffle is slidably connected to the plurality of limiting ribs through the sliding rib.

[0020] In the above coupler with a waterproof function, an installation hole communicating with the accommodating groove is provided at the bottom of the transmission frame, and the driving slider can pass through the installation hole.

[0021] The technical solution of the present invention has the following advantages compared with the prior art:

[0022] 1. The coupler with waterproof function provided by the present invention has a waterproof component in the closed position when the plug is not inserted into the socket, blocking the insertion opening to prevent external moisture from flowing into the socket. Only when the plug is inserted into the socket, the driving rod passes through the driving hole to push the driving slider, and when the driving slider moves downward along the axis of the driving hole, the waterproof component is driven by the guiding structure to move from the closed position to the open position. At this time, the waterproof component releases the blocking effect on the insertion opening, so that the pin can be smoothly inserted into the insertion opening to realize the electrical connection between the plug and the socket. By adopting this technical solution, the structure of the original waterproof gasket is cancelled, avoiding the problem of water ingress into the socket caused by the aging and cracking of the waterproof gasket. According to the transmission cooperation among the driving rod, the driving slider and the waterproof component, it is ensured that the waterproof component opens the insertion opening when the plug and the socket are inserted into each other, and closes the insertion opening when the plug and the socket are separated. The designed waterproof component will neither affect the normal insertion of the pin nor prevent external moisture from flowing into the socket, improving the safety and reliability of the coupler when used outdoors.

[0023] 2. The coupler with waterproof function provided by the present invention uses the sliding movement of the sliding baffle to cover the insertion opening to achieve the waterproof setting of the socket. Moreover, the overall strength of the sliding baffle is high and it is not easily punctured by sharp objects when used outdoors, with good safety. The sliding baffle is provided with several insertion holes corresponding to the insertion opening. When the waterproof component is in the open position, the insertion holes and the insertion opening are vertically aligned to form an insertion channel for the pin to pass through, so that the sliding baffle will not affect the insertion of the plug and the socket. When the waterproof component is in the closed position, the insertion holes and the insertion opening are staggered from each other. At this time, the sliding baffle blocks the insertion opening, thus preventing water from entering the socket.

[0024] 3. The coupler with waterproof function provided by the present invention has a guiding chute formed between the two limiting plates to guide the driving slider. When the driving rod is inserted into the driving hole, it will push the driving slider, causing the driving slider to move downward in the socket along the guiding chute, ensuring that when the driving slider is pushed by the driving rod, its sliding direction in the socket is unique and the sliding path will not deviate. The structure is simple and the transmission cooperation is reliable.

[0025] 4. The coupler with waterproof function provided by the present invention utilizes the transmission cooperation between the left guide inclined plate and the lower driving inclined surface, and the transmission cooperation between the right guide inclined plate and the upper driving inclined surface to convert the up and down movement of the driving slider into the left and right movement of the waterproof component. Even if the sliding baffle slides to the left or right along the length direction of the socket, when the sliding baffle slides to the left for a certain distance, the jack and the plug interface overlap with each other, and the waterproof component is in the open position; when the sliding baffle slides to the right for a certain distance, the jack and the plug interface are staggered, and the waterproof component is in the closed position.

[0026] 5. The coupler with waterproof function provided by the present invention, the guide slide groove includes a circular through groove and two strip limiting grooves arranged on both sides of the circular through groove, the inner diameter of the circular through groove is larger than the inner diameter of the strip limiting groove, so that when the driving slider slides in the circular through groove, it will not separate from the guide slide groove from the strip limiting groove, ensuring that the sliding path of the driving slider will not be deviated.

[0027] 6. The coupler with waterproof function provided by the present invention is characterized in that the circular sliding column is slidably arranged in the circular through groove, and the lower driving inclined surface and the upper driving inclined surface are respectively arranged in the strip-shaped limiting grooves on both sides. When the driving slider moves downward, the lower driving inclined surface will push the left guide inclined plate to move leftward and exit the strip-shaped limiting groove on the left side, so that the transmission frame moves leftward as a whole, and drives the right guide inclined plate to insert into the strip-shaped limiting groove on the right side; and when the driving slider moves upward, the right guide inclined plate is pushed by the upper driving inclined surface to exit the strip-shaped limiting groove on the right side, and the left guide inclined plate moves rightward and is inserted into the strip-shaped limiting groove on the left side. The advantage of such a design is that the circular sliding column slides up and down in the circular through groove to guide the movement of the driving slider, thereby ensuring that the driving slider moves up and down along the axial direction of the driving hole. In addition, the left and right guide inclined plates slide in the two strip-shaped limiting grooves respectively to guide the movement of the transmission frame, thereby ensuring that the transmission frame moves left and right along the length direction of the socket. The design is reasonable and the transmission is reliable.

[0028] 7. The coupler with waterproof function provided by the present invention utilizes the installation groove and the positioning hole to realize the rapid positioning and installation of the reset spring, ensuring that the reset spring will not be displaced or deformed by bending and twisting when subjected to force compression, thereby extending the service life of the spring, and the driving slider can be automatically reset with the help of the biasing force of the reset spring after the external force disappears.

[0029] 8. The coupler with waterproof function provided by the present invention is provided with sliding ridges at the bottom of the sliding baffle and limiting ridges at the top of the base. The sliding baffle is slidably connected to the limiting ridges through the sliding ridges. Through this structural arrangement, the contact area between the sliding baffle and the base is reduced, the sliding resistance of the sliding baffle is lowered, and the sliding speed of the sliding baffle is increased.

[0030] 9. The coupler with waterproof function provided by the present invention is provided with mounting holes at the bottom of the transmission frame that communicate with the accommodating grooves. When the transmission frame slides, the mounting holes can be aligned with the guiding chutes, enabling the driving sliders to be installed into the guiding chutes through the mounting holes. The structure is simple and the assembly speed of the socket is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] Embodiment 1

[0056] The following specifically describes this embodiment with reference to the drawings:

[0057] The present invention provides a coupler with a waterproof function as shown in Figure 1-12 which includes a plug 1 provided with a plurality of pins 11, and a socket 2 provided with a plurality of sockets 21 corresponding to the pins 11, and further includes:

[0058] A waterproof member 3, slidably disposed in the socket 2, having a closed position where the sockets 21 are slidably covered, and an open position where the sockets 21 are slidably opened;

[0059] The driving structure 4 includes a driving rod 41 provided on the plug 1, a driving hole 42 provided on the socket 2 for the driving rod 41 to penetrate into, and a driving slider 43 slidably connected to the waterproof component 3 along the axial direction of the driving hole 42. During the sliding process, the driving slider 43 drives the waterproof component 3 to reciprocate between the closed position and the open position through a guiding structure. According to the design requirements, the length of the driving rod 41 must be greater than the length of the pin 11 to ensure that the driving rod 41 first inserts into the driving hole 42 and pushes against the driving slider 43. When the driving rod 41 inserts into the driving hole 42, the driving slider 43 is pushed downward and drives the waterproof component 3 to move from the closed position to the open position. When the driving rod 41 withdraws from the driving hole 42, the driving slider 43 can elastically reset to block the driving hole 42 and drive the waterproof component 3 to move from the open position to the closed position.

[0060] The above implementation manner is the core technical solution of this embodiment. When the socket 2 is not plugged with the plug 1, the waterproof component 3 is in the closed position, blocking the plug interface 21 to prevent external moisture from flowing into the socket 2. Only when the plug 1 is inserted into the socket 2, the driving rod 41 passes through the driving hole 42 and pushes against the driving slider 43. When the driving slider 43 moves downward along the axial direction of the driving hole 42, it drives the waterproof component 3 to move from the closed position to the open position through the guiding structure. At this time, the waterproof component 3 releases the blocking effect on the plug interface 21, so that the pin 11 can be smoothly inserted into the plug interface 21 to realize the electrical connection between the plug 1 and the socket 2. By adopting this technical solution, the structure of the original waterproof gasket is cancelled, avoiding the problem of water ingress into the socket 2 caused by the aging and cracking of the waterproof gasket. According to the transmission cooperation between the driving rod 41, the driving slider 43 and the waterproof component 3, it is ensured that the waterproof component 3 opens the plug interface 21 when the plug 1 and the socket 2 are plugged together, and closes the plug interface 21 when the plug 1 and the socket 2 are separated. The waterproof component 3 designed in this way will neither affect the normal insertion of the pin 11 nor prevent external moisture from flowing into the socket 2, improving the safety and reliability of the coupler when used outdoors.

[0061] As a specific structural arrangement, a plurality of the insertion interfaces 21 are sequentially and spaced apart along the length direction of the socket 2 at the top of the socket 2. The waterproof component 3 reciprocally moves along the length direction of the socket 2 under the drive of the drive structure 4. It includes a sliding baffle 31 movably arranged inside the top of the socket 2, a transmission frame 32 connecting the sliding baffle 31 and the drive slider 43 in a sliding connection, and a plurality of jacks 33 correspondingly arranged on the sliding baffle 31 for the insertion interfaces 21. The insertion interfaces 21 are covered by the sliding movement of the sliding baffle 31 to achieve the waterproof setting of the socket 2. Moreover, the overall strength of the sliding baffle 31 is high, and it is not easily punctured by sharp objects during outdoor use, with good safety. For example, Figure 2 and Figure 3 shown, during the reciprocating movement of the waterproof component 3, a plurality of the jacks 33 coincide and connect or are misaligned and separated from a plurality of the insertion interfaces 21. When the waterproof component 3 is in the open position, referring to Figure 5 , the jacks 33 and the insertion interfaces 21 are vertically opposite to each other, forming a plugging channel for the insertion pins 11 to pass through, so that the sliding baffle 31 will not affect the plugging of the plug 1 and the socket 2. When the waterproof component 3 is in the closed position, the jacks 33 and the insertion interfaces 21 are staggered from each other. At this time, the sliding baffle 31 blocks the insertion interfaces 21, thereby avoiding the problem of water ingress into the socket 2.

[0062] The following will describe the guiding structure in detail in conjunction with Figure 4 、 Figure 6 and Figure 8 :

[0063] The guiding structure includes: two limiting plates 22 arranged inside the socket 2 and distributed on both sides of the driving hole 42, and a guiding chute 23 formed between the two limiting plates 22 and axially aligned with the driving hole 42. The drive slider 43 is movably arranged in the guiding chute 23 along the axial direction of the driving hole 42, and a transmission guiding component is arranged between the drive slider 43 and the transmission frame 32 for guiding the sliding baffle 31 to reciprocally move along the length direction of the socket 2. The guiding chute 23 plays a role in guiding the movement of the drive slider 43. When the drive rod 41 is inserted into the driving hole 42, it will push against the drive slider 43, causing the drive slider 43 to move downward in the socket 2 along the guiding chute 23, ensuring that the sliding direction of the drive slider 43 in the socket 2 is unique when being pushed by the drive rod 41, and the sliding path will not deviate. The structure is simple and the cooperation is reliable.

[0064] In order to reliably realize the transmission cooperation between the transmission frame 32 and the driving slider 43, the transmission frame 32 includes a receiving groove 34 suitable for accommodating the two limit plates 22 and the driving slider 43. As a preferred embodiment, combined with Figure 4 and Figure 6 As shown, the transmission guide assembly includes a left guide inclined plate 51 and a right guide inclined plate 52 which are obliquely arranged on the groove walls on both sides of the accommodating groove 34, and a lower driving inclined surface 53 and an upper driving inclined surface 54 which are arranged on both sides of the driving slider 43 in a high and low manner and are back-to-back; when the driving slider 43 moves downward along the guide slot 23, the lower driving inclined surface 53 slides against the left guide inclined plate 51 to push the waterproof component 3 from the closed position to the open position, and when the driving slider 43 moves upward along the guide slot 23, the upper driving inclined surface 54 slides against the right guide inclined plate 52 to push the waterproof component 3 from the open position to the closed position. By utilizing the transmission cooperation between the left guide inclined plate 51 and the lower driving inclined surface 53 and the transmission cooperation between the right guide inclined plate 52 and the upper driving inclined surface 54, the up and down movement of the driving slider 43 is converted into the left and right movement of the waterproof component 3, that is, the sliding baffle 31 is driven to slide leftward or rightward along the length direction of the socket 2, with reference to FIG. Figure 2 and Figure 5 It can be seen that when the sliding baffle 31 slides to the left for a certain distance, the plug hole 33 and the plug port 21 overlap with each other, and at this time the waterproof component 3 is in the open position; Figure 3 It can be seen that when the sliding baffle 31 slides to the right by a certain distance, the plug hole 33 and the plug port 21 are staggered from each other, and at this time, the waterproof component 3 is in a closed position.

[0065] As a specific structural setting, the two limiting plates 22 extend a set distance along the length direction of the socket 2, and the guide slot 23 includes a circular through slot 24 axially opposite to the driving hole 42, and two strip limiting slots 25 extending from the two end ports of the two limiting plates 22 and connected to the circular through slot 24, such as Figure 9 As shown, the inner diameter of the circular through groove 24 is larger than the inner diameter of the strip-shaped limiting groove 25, so that the driving slider 43 will not deviate to the strip-shaped limiting groove 25 when sliding in the circular through groove 24, and the left guide inclined plate 51 and the right guide inclined plate 52 are respectively slidably connected in the two strip-shaped limiting grooves 25, and further provided, as shown in FIG. Figure 4 and Figure 6As shown in the figure, the driving slider 43 includes a circular sliding column 44 that is slidably connected to the circular through groove 24 in a matching manner, and a lower driving inclined surface 53 and an upper driving inclined surface 54 that are formed on the side wall of the circular sliding column 44 and respectively penetrate through the two strip-shaped limiting grooves 25. With such a structural arrangement, when the driving slider 43 moves downward, the left guiding inclined plate 51 is slidably pushed by the lower driving inclined surface 53, causing the left guiding inclined plate 51 to move leftward under force and withdraw from the left strip-shaped limiting groove 25, resulting in the overall leftward movement of the transmission frame 32 and driving the right guiding inclined plate 52 to insert into the right strip-shaped limiting groove 25; and when the driving slider 43 moves upward, the right guiding inclined plate 52 is pushed by the upper driving inclined surface 54 to move out of the right strip-shaped limiting groove 25, and at the same time drives the left guiding inclined plate 51 to insert into the left strip-shaped limiting groove 25. The advantage of such a design is that the up-and-down sliding of the circular sliding column 44 in the circular through groove 24 guides the movement of the driving slider 43, thereby ensuring that the driving slider 43 moves up and down along the axis of the driving hole 42. In addition, the sliding of the left and right guiding inclined plates in the two strip-shaped limiting grooves 25 respectively guides the movement of the transmission frame 32, thereby ensuring that the transmission frame 32 moves left and right along the length direction of the socket 2. The design is reasonable and the cooperation is reliable.

[0066] In order to enable the driving slider 43 to automatically reset, a reset spring 6 is provided between the driving slider 43 and the bottom surface of the socket 2. The biasing force direction of the reset spring 6 acting on the driving slider 43 is opposite to the thrust direction of the driving rod 41 acting on the driving slider 43, so that the driving slider 43 can achieve automatic reset by means of the biasing force of the reset spring 6 when not pushed by the driving rod 41; as Figure 4 shown in the figure, an installation groove 61 for installing one end of the reset spring 6 is provided at the bottom of the circular sliding column 44, and a positioning hole 62 for installing the other end of the reset spring 6 is provided on the bottom surface of the socket 2. The quick positioning installation of the reset spring 6 is realized by using the installation groove 61 and the positioning hole 62, ensuring that the reset spring 6 will not undergo position offset and bending and torsion deformation when being compressed by force, and prolonging the service life of the spring.

[0067] As a specific structural setting, a raised end 45 suitable for inserting into the driving hole 42 and flush with the top surface of the socket 2 is provided at the top of the circular sliding post 44. By setting the raised end 45, when the driving rod 41 is inserted into the driving hole 42, it remains in close contact with the driving slider 43, making the thrust received by the driving slider 43 more stable. Moreover, a sealing ring 46 is provided between the raised end 45 and the driving hole 42 to prevent external moisture from flowing into the interior of the socket 2 through the driving hole 42. Further, a plurality of grooves are correspondingly provided at the top of the sliding baffle 31 on one side of a plurality of the jacks 33, and sealing gaskets 35 are installed in the grooves. When the waterproof component 3 is in the closed position, the plurality of sealing gaskets 35 respectively block the plurality of plug interfaces 21, and the raised end 45 is sealed in the driving hole 42 through the sealing ring 46. The overall waterproof performance of the socket 2 is improved through the sealing ring 46 and the sealing gaskets 35, and even when the sealing gaskets 35 are punctured by foreign objects from the outside, moisture will not directly flow into the socket 2, which has high safety and better waterproof effect.

[0068] As Figure 4 , Figure 6 and Figure 8 As shown, the socket 2 includes an upper cover 26, a base 27, a first installation cavity 28, and a second installation cavity 29. A plurality of the plug interfaces 21, the driving hole 42, and two limiting plates 22 provided on the inner wall of the upper cover 26 are provided on the upper cover 26; corresponding plug terminals 271 to the plurality of the plug interfaces 21 are provided on the base 27, and the base 27 is installed with the upper cover 26 to form the socket 2; the first installation cavity 28 is formed between the upper cover 26 and the top of the base 27, and the sliding baffle 31 is slidably arranged in the first installation cavity 28 along the length direction of the socket 2; the second installation cavity 29 is formed between the side surfaces of the upper cover 26 and the base 27, and the transmission frame 32 is integrally formed in an L shape on one side edge of the sliding baffle 31 and is slidably arranged in the second installation cavity 29; the first installation cavity 28 and the second installation cavity 29 are communicated to provide sufficient sliding space for the sliding baffle 31 and the transmission frame 32.

[0069] To reduce the frictional resistance between the sliding baffle 31 and the base 27, referring to Figure 12, at the bottom of the sliding baffle 31, at least one sliding rib 36 is arranged along the length direction of the socket 2. At the top of the base 27, a plurality of limiting ribs 272 intersecting with the sliding rib 36 are arranged at intervals along the extending direction of the sliding rib 36. The sliding baffle 31 is slidably connected to the plurality of limiting ribs 272 through the sliding rib 36. Through this structural arrangement, the contact area between the sliding baffle 31 and the base 27 is reduced, the sliding resistance of the sliding baffle 31 is lowered, and the sliding speed of the sliding baffle 31 is increased.

[0070] As Figure 10 and Figure 11 shown, at the bottom of the transmission frame 32, an installation hole 37 communicating with the accommodation groove 34 is provided. When the transmission frame 32 slides, the installation hole 37 can be aligned with the guiding chute 23, so that the driving slider 43 can pass through the installation hole 37 and be installed into the guiding chute 23. The structure is simple and the assembly speed of the socket 2 is increased.

[0071] Next, in conjunction with Figure 4 and Figure 6 the working principle of the coupler with waterproof function in this embodiment will be described:

[0072] When the plug 1 is inserted into the socket 2, the driving rod 41 is first inserted into the driving hole 42 to push the driving slider 43. The driving slider 43 moves downward along the guiding chute 23 to squeeze the return spring 6, and drives the lower driving inclined surface 53 to slide and push the left guiding inclined plate 51. The left guiding inclined plate 51 is forced to move leftward to drive the entire transmission frame 32 to move leftward, thereby driving the sliding baffle 31 to move leftward so that the jack 33 coincides with the insertion port 21. At this time, the pin 11 can pass through the insertion port 21 and the jack 33 to be connected to the socket terminal 271, realizing the electrical connection between the plug 1 and the socket 2.

[0073] When the plug 1 is pulled out of the socket 2, the driving rod 41 exits the driving hole 42. At this time, the return spring 6 elastically resets to push the driving slider 43 upward to the driving hole 42, and drives the upper driving inclined surface 54 to slide and push the right guiding inclined plate 52, causing the transmission frame 32 to move rightward, thereby driving the sliding baffle 31 to move rightward so that the sealing gasket 35 slides to block a plurality of the insertion ports 21, thereby realizing the waterproof function of the socket 2.

[0074] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
