Detailed Implementation

[0033] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0034] The socket includes a socket sleeve disposed inside the socket and a plug hole disposed on the socket. The socket interior includes at least one set of socket sleeves, and each set of socket sleeves includes at least two sets of clamping arms. The socket is provided with at least one set of plug holes, and each set of plug holes includes at least two pin holes. A protective door structure is provided between the plug hole and the socket sleeve. The protective door structure is used to cover the plug hole of the socket when the socket is not in use to prevent small objects from entering and causing safety problems.

[0035] The protective door structure of this application includes at least one protective door 1 and at least one elastic element 2. The at least one elastic element 2 is correspondingly connected to the at least one protective door 1. A first through hole 11 is provided on the protective door 1, through which the N-pole or L-pole pin passes. After the elastic element 2 is connected to the protective door 1, it drives the protective door 1 to block the space between the plug hole and the socket. The elastic element 2 can be, but is not limited to, a compression spring, a spring, or a tension spring. In this embodiment, the elastic element 2 is a compression spring. For ease of understanding, [the following is a simplified explanation]. Figure 1 The thickness direction of the socket is defined as the first direction D1, the width direction of the socket is defined as the second direction D2, and the height direction of the socket is defined as the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0036] like Figures 1-13 As shown, the socket is provided with at least two sliding grooves 32, and the protective door 1 is provided with sliding shafts 33 on both sides. The two sliding shafts 33 are slidably installed on the two sliding grooves 32.

[0037] The slide 32 includes a bent guide section 321 and a guide section 322. The length direction of the guide section 321 is in a first direction D1, and the length direction of the guide section 322 is inclined and is in a fourth direction D4. The angle between the guide section 321 and the guide section 322 is an obtuse angle. The side of the protective door 1 facing the plug hole is the upper surface, which is a planar structure. The elastic member 2 makes the upper surface of the protective door 1 completely fit with the plane where the plug hole is located, which can play a role in dust prevention.

[0038] The protective door 1 moves back and forth between a first position and a second position. When the protective door 1 is in the first position, it completely blocks at least two pin holes (including the L-pole pin hole and the N-pole pin hole) of the plug hole. The sliding shaft 33 of the protective door 1 is located in the guide section 321 and at the end of the guide section 321 away from the guide section 322. When the protective door 1 is in the second position, it is offset from the blocked at least two pin holes, so that the plug can be inserted into the plug hole and connected to the socket. The sliding shaft 33 of the protective door 1 is located in the guide section 322 of the slide groove 32 and at the end of the guide section 322 away from the guide section 321.

[0039] likeFigure 6 and Figure 13 As shown, under normal conditions, the elastic element 2 keeps the protective door 1 in the first position. When the protective door 1 is subjected to an external force (e.g., when a plug is inserted into a plug hole), the protective door 1 slides from the guide section 321 to the guide section 322 along the first direction D1. When the protective door 1 continues to be subjected to force, the sliding shaft 33 of the protective door 1 slides from the guide section 321 to the guide section 322. The guide section 322 changes the sliding direction of the protective door 1. The protective door 1 slides along the fourth direction D4 in the guide section 322. When the protective door 1 slides in the fourth direction D4, it generates displacement in both the first direction D1 and the second direction D2.

[0040] Preferred, such as Figure 13 As shown, the guide segment 321 includes a parallel first guide edge 3211 and a second guide edge 3212, and the guide segment 322 includes a parallel first guide edge 3221 and a second guide edge 3222. The first guide edge 3211 and the first guide edge 3221 are bent and connected, and the included angle is an obtuse angle. The second guide edge 3212 and the second guide edge 3222 are bent and connected, and the included angle is an obtuse angle.

[0041] In particular, this application can also prevent single-pole insertion. The slide groove 32 includes a bent guide section 321 and a guide section 322, and the included angle between them is an obtuse angle. When the protective door 1 is inserted by a single pole, the force-bearing end of the protective door 1 sinks and is limited, and the protective door 1 cannot continue to rotate. Because the vertical guide section 321 is provided, the sliding shaft 33 of the protective door 1 can be in the guide section 321 during this process. The single pole insertion is difficult to drive the sliding shaft 33 to the guide section 322, so that the protective door 1 can continue to block the plug hole and prevent single pole insertion.

[0042] Preferably, the protective door 1 includes a through-axis surface, which is parallel to the upper surface of the protective door 1 and passes through two sliding shafts 33. When the protective door 1 is in the first position, the through-axis surface intersects with the guide section 321. When the protective door 1 is in the second position, the through-axis surface intersects with the guide section 322. When the protective door 1 is tilted due to the insertion of a single pole, and one end of the protective door 1 abuts against the plane of the plug hole, and / or the other end of the protective door 1 abuts against the pressure plate 35, the through-axis surface of the protective door 1 always intersects with the guide section 321, preventing the protective door 1 from continuing to rotate. The protective door 1 continues to block the plug hole, ensuring that the sliding shaft 33 of the protective door 1 is in the guide section 321 during this process. The sliding shaft 33 can be located at the end of the guide section 321 away from the guide section 322, or it can slide within the guide section 321, but it will not slide to the guide section 322 and will not be displaced in the second direction D2. Therefore, it can produce the effect of preventing single pole insertion. It should be noted that the through-axis surface is a virtual plane that is parallel to the upper surface and passes through the sliding shaft 33.

[0043] Preferred, such asFigures 1-5 and Figure 12 As shown, the protective door structure includes a pressure plate 35, and the protective door 1 is slidably disposed on the pressure plate 35. The pressure plate 35 includes at least one set of second sidewalls 312 and fourth sidewalls 314 that are arranged relatively apart. The protective door 1 is slidably installed on the second sidewalls 312 and fourth sidewalls 314, and two sliding grooves 32 are formed on the second sidewalls 312 and fourth sidewalls 314.

[0044] Alternatively, the pressure plate 35 includes at least one protective door mounting groove 31, with at least one protective door 1 slidably mounted in each groove 31. The protective door mounting groove 31 includes a first sidewall 311, a second sidewall 312, a third sidewall 313, and a fourth sidewall 314. The first sidewall 311 and the third sidewall 313 are opposite each other, and the second sidewall 312 and the fourth sidewall 314 are opposite each other. Two sliding grooves 32 are formed on the second sidewall 312 and the fourth sidewall 314. Figure 12 A schematic diagram of the structure of the pressure plate 35 of this application is shown.

[0045] Furthermore, the bottom of the pressure plate 35 is provided with one or more first through holes 34, which are used for the pin to pass through.

[0046] In one embodiment, such as Figure 1 As shown, the socket includes a socket base 41 and a socket cover 42. At least one set of socket sleeves is disposed within the socket base 41, and at least one set of plug holes is disposed on the socket cover 42. The pressure plate 35 is disposed between the socket sleeves and the socket cover 42. When the protective door 1 is in the first position, the upper surface of the protective door 1 is tightly fitted against the side of the socket cover 42 facing the protective door 1.

[0047] The pressure plate 35 is disposed inside the socket base 41, and the socket cover 42 covers the socket base 41 and / or the socket cover 42 covers the pressure plate 35;

[0048] Alternatively, the socket cover 42 and the pressure plate 35 are modularly designed. The socket cover 42 covers the pressure plate 35, and the pressure plate 35 is detachably installed on the socket base 41. The modular design makes installation and disassembly convenient, facilitates maintenance and replacement, reduces the number of internal parts of the socket, facilitates management, and is suitable for automated assembly.

[0049] Furthermore, in this embodiment, the elastic element 2 is installed between the socket base 41 and the protective door 1. One end of the elastic element 2 is installed on the socket base 41 through the first through hole 34, and the other end is installed on the back of the protective door 1.

[0050] Furthermore, the elastic element 2 is disposed between the pressure plate 35 and the protective door 1, with one end of the elastic element 2 installed at the bottom of the pressure plate 35 and the other end installed on the back of the protective door 1.

[0051] Furthermore, the socket base 41 or pressure plate 35 is provided with a first groove 14 or a first protrusion, and the back of the protective door 1 is provided with a second groove or a second protrusion 13. One end of the elastic member 2 is installed on the first groove 14 or the first protrusion, and the other end is installed on the second groove or the second protrusion 13. In this embodiment of the application, as shown... Figure 3 and Figure 6 As shown, a first groove 14 is provided on the socket base 41, and a second protrusion 13 is provided on the back of the protective door 1.

[0052] Furthermore, the protective door structure also includes a protective door cover. The protective door 1 is installed inside the pressure plate 35, and the protective door cover is fitted onto the pressure plate 35. The protective door cover includes multiple second through holes, which are structurally consistent with and positionally correspond to the pin holes of the plug hole. After the pin passes through the plug hole on the socket cover 42, the second through holes on the protective door cover, and the first through hole 34 of the pressure plate 35, it is inserted into the socket base 41. The elastic element 2 drives the protective door 1 to block between the second through holes and the socket base. In a preferred embodiment, the protective door structure is modularly designed. The elastic element 2 is installed between the pressure plate 35 and the protective door 1. The modular design of the protective door structure makes installation and disassembly convenient, facilitates maintenance and replacement, reduces the number of internal parts of the socket, facilitates management, and is suitable for automated assembly.

[0053] Preferred, such as Figures 1-12As shown, the first through hole 11 includes a first side 111 and a second side 112 opposite to each other. The end of the protective door 1 away from the first through hole 11 includes a third side 113. A baffle 421 is provided inside the socket. The baffle 421 is located in the plane of the first direction D1 and the third direction D3. The baffle 421 includes a first surface and a second surface opposite to each other. The baffle 421 extends into the first through hole 11. The thickness of the baffle 421 is less than the width of the first through hole 11. In a preferred embodiment, when the protective door 1 is in the first position, the first side 111 of the first through hole 11 abuts against the first surface of the baffle 421, and the third side 113 of the protective door 1 abuts against the first sidewall 311. When the protective door 1 is in the second position, the second side 112 of the first through hole 11 abuts against the second surface of the baffle 421, and the third side 113 of the protective door 1 is spaced apart from the first sidewall 311, with the gap between the third side 113 and the first sidewall 311 corresponding to a pin hole. The distance between the first side 111 and the second side 112 of the first through hole 11 is the displacement of the protective door 1 in the second direction D2 when it slides from the first position to the second position. The first through hole 11 provides sliding space for the protective door 1. When the protective door 1 is in the first position, the first through hole 11 is hidden inside the socket. When the protective door 1 is slid to the second position by external force, the first through hole 11 corresponds to a pin hole. The baffle 421 can satisfy the requirement that when a single pole is inserted into the protective door 1, the baffle 421 abuts against the second side 112 of the first through hole 11 to achieve a limiting effect, thus preventing single pole insertion. Figure 11 A structural schematic diagram of the back of the socket cover 42 is shown.

[0054] Furthermore, such as Figures 1-5 and Figure 12 As shown, the third side 113 of the protective door 1 includes a protruding first extension 12. The first extension 12 extends away from the first through hole 11 along the length direction of the protective door 1. A first limiting structure is provided on one or both sides of the first extension 12 opposite to each other along the thickness direction. A second limiting structure is provided in the socket to cooperate with the first limiting structure for limiting. A recessed clearance area 123 that cooperates with the first extension 12 is provided on one or both sides of the first sidewall 311. The clearance area 123 may include the second limiting structure. When the protective door 1 moves vertically along the guide section 321, the first extension 12 is located in the clearance area 123 and also moves vertically along the clearance area 123. When the protective door 1 moves tilted along the guide section 322, the first extension 12 moves vertically along the clearance area 123 and moves away from the clearance area 123. When the protective door 1 is in the second position, the first extension 12 is at least partially located in the clearance area 123.

[0055] Preferably, the baffle 421 includes a first end and a second end.

[0056] Furthermore, the baffle 421 is disposed between the socket cover 42 and the pressure plate 35. The first end of the baffle 421 is integrally formed with the socket cover 42, and the bottom of the pressure plate 35 is provided with a first limiting part, which cooperates with the second end of the baffle 421 for limiting; or the first end of the baffle 421 is integrally formed with the bottom of the pressure plate 35, and the socket cover 42 is provided with a first limiting part, which cooperates with the second end of the baffle 421 for limiting.

[0057] Furthermore, the baffle 421 is disposed between the protective door cover and the pressure plate 35. The first end of the baffle 421 is integrally formed with the protective door cover, and the bottom of the pressure plate 35 is provided with a first limiting part, which cooperates with the second end of the baffle 421 for limiting; or the first end of the baffle 421 is integrally formed with the bottom of the pressure plate 35, and the protective door cover is provided with a first limiting part, which cooperates with the second end of the baffle 421 for limiting.

[0058] By providing a first limiting part to support the baffle 421, the service life of the baffle 421 can be improved. In addition, the design of the first limiting part can also prevent the socket cover 42 or the protective door cover from being installed backwards.

[0059] Furthermore, such as Figure 6 and Figure 12 As shown, the first limiting part is a support block 317. When the protective door 1 tilts to abut against the baffle 421 on one side, the baffle 421 is subjected to force and transferred to the support block 317. This arrangement helps the support block 317 to improve the fatigue service life of the baffle 421.

[0060] In this embodiment of the application, the support block 317 is one or more. By using multiple support blocks 317 to support the second end of the baffle 421, the above-mentioned effect can be further optimized.

[0061] Preferred, such as Figures 2-5 As shown, the third side 113 of the protective door 1 includes two first extensions 12, and the two sides of the first sidewall 311 are provided with clearance areas 123. When the protective door 1 is in the second position, at least two pins on the plug, one pin can be connected to the socket through the first through hole 11, and the other pin passes through the two first extensions 12 and is connected to the socket.

[0062] Alternatively, the third side 113 of the protective door 1 includes a first extension 12, and a clearance area 123 is provided on one side of the first sidewall 311. When the protective door 1 is in the second position, at least two pins on the plug can be connected to the socket through the first through hole 11, and the other pin can be connected to the socket through one side of the first extension 12.

[0063] When the protective door 1 is inserted by a single pole, one end of the protective door 1 is subjected to force and sinks, making a rocker motion on the pressure plate 35. When the end of the protective door 1 away from the first extension 12 is subjected to force and sinks (such as...), Figure 9 and Figure 10 As shown), the first extension 12 is raised and abuts against the second limiting part on the protective door cover or socket cover 42; when the end of the first extension 12 is subjected to force and sinks (as shown), Figure 7 and Figure 8 As shown, the first extension 12 abuts against the second limiting part on the pressure plate 35, preventing the protective door 1 from continuing to rotate and avoiding the protective door 1 from rotating within the pressure plate 35 and thus releasing the obstruction of the force-bearing end pin hole. This achieves the technical effect of the protective door structure of the socket in this application in preventing single-pole insertion.

[0064] In a preferred embodiment, such as Figure 6 As shown, when the protective door 1 is not driven by an external force, the protective door 1 is in the first position. The second protrusion 13 on the protective door 1 and the first groove 14 on the socket base 41 are a certain distance apart in the first direction D1. That is, the second protrusion 13 on the protective door 1 and the first groove 14 on the socket base 41 are misaligned in the first direction D1. After the elastic member 2 is connected to the second protrusion 13 and the first groove 14, it is in an inclined position. The inclined setting of the elastic member 2 is to provide the protective door 1 with the initial potential energy to move to the first position, so that the protective door 1 has a better shielding effect and further improves the safety of the socket.

[0065] Furthermore, such as Figure 6 As shown, a first limiting protrusion 422 is provided on the back of the socket cover 42 or the protective door cover. When the protective door 1 is in the first position, the first limiting protrusion 422 and the baffle 421 limit one end of the protective door 1 in the second direction D2. The protective door 1 is simultaneously subjected to force at both ends, causing the protective door 1 to slide along the guide section 321 of the sliding shaft 33 towards the guide section 322. The protective door 1 gets rid of the limitation of the first limiting protrusion 422 and the baffle 421, allowing the protective door 1 to be displaced in the second direction D2. By providing a first limiting protrusion 422 on the back of the socket cover 42 or the protective door cover to limit one end of the protective door 1, when the protective door 1 is reset to the first position, one end of the protective door 1 is stuck between the first limiting protrusion 422 and the baffle 421, and the elastic member 2 is in the tilted position.
