Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a socket. Background Technology

[0002] Existing sockets have protective doors to block the plug holes when the socket is not in use. Sometimes, designers will install a baffle inside the socket to limit the protective door, in order to prevent the protective door from being opened by a foreign object such as an iron bar when a single plug hole is hit. One end of the baffle is integrally formed with the internal structure of the socket, while the other end is exposed. This causes the baffle to deform and bend when subjected to external force, thus failing to block the protective door and posing a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a socket that can fix both ends of the baffle at the same time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The socket further includes at least one protective door and at least one elastic element. The at least one protective door is slidably disposed within the socket. When the elastic element drives the protective door to slide to a first position, the protective door blocks the corresponding socket and plug hole. When the protective door slides to a second position after being subjected to external force, overcoming the elastic element, the protective door is misaligned with the plug hole.

[0007] The protective door includes a first through hole. When the elastic element drives the protective door to slide to a first position, the first through hole is misaligned with a plug hole. When the protective door slides to a second position after being subjected to external force, overcoming the elastic element, the first through hole corresponds to one of the plug holes. At least one baffle is provided inside the socket, the baffle passing through the first through hole. At least one end of the baffle includes a first fixing part. A second fixing part is provided inside the socket to lock in place with the first fixing part.

[0008] The first fixing part includes the end of the baffle, and the second fixing part includes at least one slot, into which the first fixing part is inserted.

[0009] In one possible implementation, the first fixing part includes two first extensions protruding from the end of the baffle, the two first extensions being spaced apart, and the second fixing part includes two slots, the two first extensions being inserted into the two slots respectively.

[0010] In one possible implementation, the first fixing part includes a first extension protruding from the end of the baffle and an abutment part located on one side of the first extension part, and the first extension part protruding from the abutment part. The second fixing part includes a fixing platform and a slot, the first extension part being inserted into the slot, and the abutment part abutting against the fixing platform.

[0011] In one possible implementation, the socket includes a pressure plate, a socket base, and a socket cover. At least one set of inserts is disposed within the socket base, and at least one set of plug holes is disposed on the socket cover. The pressure plate is disposed between the inserts and the socket cover.

[0012] In one possible implementation, the pressure plate is disposed within the socket base, and the socket cover is fitted onto the socket base and / or the pressure plate;

[0013] Alternatively, the pressure plate can be detachably mounted on the socket base, and the socket cover can be fitted onto the pressure plate.

[0014] In one possible implementation, the two ends of the baffle are a first end and a second end, respectively.

[0015] The baffle is disposed between the socket cover and the pressure plate. The first end of the baffle is integrally formed with the socket cover, and the second end of the baffle includes the first fixing part. The bottom of the pressure plate includes the second fixing part. Alternatively, the second end of the baffle is integrally formed with the bottom of the pressure plate, the first end of the baffle includes the first fixing part, and the back of the socket cover includes the second fixing part.

[0016] In one possible implementation, the pressure plate includes at least one set of opposing second and fourth sidewalls, and the protective door is slidably mounted on the second and fourth sidewalls; two sliding shafts are provided on both sides of the protective door, and two sliding grooves are provided on the second and fourth sidewalls to cooperate with the sliding shafts; the sliding grooves include a vertical guide section and an inclined guide section, the guide section and the guide section are bent and connected, and the included angle between them is an obtuse angle; when the protective door is in a first position, it is located within the guide section and away from the guide section; when the protective door is in a second position, it is located within the guide section and away from the guide section.

[0017] In one possible implementation, the pressure plate includes at least one protective door mounting groove, the protective door being slidably mounted within the protective door mounting groove, the protective door mounting groove including a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, the first sidewall and the third sidewall being opposite to each other, and the second sidewall and the fourth sidewall being opposite to each other.

[0018] In one possible implementation, the first through hole includes opposing first and second sides, and a third side is included at the end away from the first through hole. When the protective door is in a first position, the first side contacts the side of the baffle, and the third side contacts the first sidewall. When the protective door is in a second position, the first side is spaced apart from the baffle, and the third side is spaced apart from the first sidewall, with the gap between the third side and the first sidewall corresponding to another pin hole.

[0019] The third side includes at least one protruding second extension. The pressure plate is provided with a recessed clearance area that cooperates with the second extension. The clearance area is located on one or both sides of the first sidewall. The second extension extends into the clearance area. When the protective door moves vertically along the guide section, the second extension is located in the clearance area and also moves vertically along the clearance area. When the protective door moves tilted along the guide section, the second extension moves vertically along the clearance area and moves away from the clearance area. When the protective door is in the second position, the second extension is at least partially located within the clearance area.

Detailed Implementation

[0035] 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.

[0036] 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 an L-pole pin hole and an N-pole pin hole. A protective door structure is provided between the plug hole and the socket sleeve. The protective door structure is used to block the plug hole of the socket when the socket is not in use to prevent small objects from entering and causing safety problems.

[0037] The protective door structure of this application includes at least one protective door 1 and at least one elastic element 2, with the at least one elastic element 2 and at least one protective door 1 correspondingly connected, driving the protective door 1 to block between the plug hole and the socket. The elastic element 2 may be, but is not limited to, a compression spring, a spring, or a tension spring. In the embodiments of this application, the elastic element 2 is a compression spring.

[0038] Preferably, the protective door 1 reciprocates between a first position and a second position. The elastic element 2 drives the protective door 1 to slide from the second position to the first position. The protective door 1 is driven to slide from the first position to the second position by an external force that overcomes the force of the elastic element 2. In the first position, the protective door 1 blocks at least two pin holes of the plug hole. In the second position, the protective door 1 is offset from the plug hole, allowing the plug to be inserted into the plug hole.

[0039] To make it easier to understand, 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.

[0040] like Figures 1-10 As shown, the protective door 1 includes a first through hole 11 for either the N-pole or L-pole pin to pass through. A baffle 421 is provided inside the socket, located in the plane containing the first direction D1 and the third direction D3, and passes through the first through hole 11. The baffle 421 includes a first side and a second side facing away from each other. The first through hole 11 includes opposing first sides 111 and second sides 112. The end of the protective door 1 away from the first through hole 11 includes a third side 113. 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 and the first through hole 11 is misaligned with the L-pole pin hole or the N-pole pin hole. When the protective door 1 is slid to the second position by external force, the first through hole 11 corresponds to the L-pole pin hole or the N-pole pin hole. One of the L-pole pins and the N-pole pins on the plug are connected to the socket through the first through hole 11, and the other pin passes through from the third side 113 and is connected to the socket.

[0041] At least one end of the baffle 421 includes a first fixing part, and the socket is provided with a second fixing part that cooperates with and locks to the first fixing part.

[0042] Preferably, the first fixing part may include the end of the baffle 421, and the second fixing part includes at least one slot 316 disposed inside the socket. The end of the baffle 421 is inserted into the slot 316. Compared with the prior art, by providing at least one slot 316 inside the socket, the end of the baffle 421 can be inserted into the slot 316 to achieve a good fixing effect on the baffle 421. It can also play a supporting and limiting role for the baffle 421, so that the baffle 421 will not be damaged by large deformation when subjected to force.

[0043] Furthermore, the first fixing part includes at least one first extension 422, which protrudes from the end of the baffle 421 and extends along the length direction of the baffle 421. The second fixing part includes at least one slot 316, into which the first extension 422 is inserted. By providing the first extension 422 at the end of the baffle 421 and inserting it into the slot 316, a better insertion and fixing effect is achieved.

[0044] Furthermore, such as Figures 11a-12b As shown, the first fixing part includes two first extensions 422, which are spaced apart. Correspondingly, the second fixing part includes two slots 316 that are spaced apart.

[0045] Furthermore, such as Figures 11a-12b As shown, the first fixing part includes a first extension 422 and an abutment 423. The abutment 423 is located on one side of the first extension 422, and the first extension 422 protrudes from the abutment 423. The second fixing part includes a slot 316 and a fixing platform 317. The first extension 422 is inserted into the slot 316, and the abutment 423 abuts against the fixing platform 317. After the first extension 422 is inserted into the slot 316, the abutment 423 abuts against the fixing platform 317, and the fixing platform 317 provides support for the end of the baffle 421. While reducing the number of slots 316 and the first extension 422, it still provides good support and fixing effect for the baffle. Reducing the number of slots 316 and the first extension 422 can reduce process steps and improve production efficiency.

[0046] By providing a slot 316 and / or a fixing platform 317 to fix and support the end of the baffle 421, the service life of the baffle 421 can be improved.

[0047] Preferred, such as Figure 1 and Figure 12aAs shown, the socket includes a pressure plate 35, a socket base 41, and a socket cover 42. At least one set of inserts is disposed inside 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 inserts and the socket base 41. The bottom of the pressure plate 35 is provided with at least one first through hole 34, which can be used for the plug to pass through.

[0048] Furthermore, the pressure plate 35 is disposed inside the socket base 41, and the socket cover 42 covers the socket base 41 and / or the pressure plate 35;

[0049] Alternatively, the pressure plate 35 can be detachably installed on the socket base 41, and the socket cover 42 can be placed on the pressure plate 35, making the protective door structure modular, easy to install and disassemble, convenient for maintenance and replacement, reducing the number of internal parts of the socket for easier management, and suitable for automated assembly.

[0050] Preferably, the protective door structure further includes a protective door cover. The protective door 1 is mounted on the pressure plate 35, and the protective door cover is closed on the pressure plate 35. The elastic element 2 is installed between the pressure plate 35 and the protective door 1. The protective door cover includes multiple second through holes, which have the same structure and corresponding position as the pin hole of the plug hole. The elastic element 2 drives the protective door 1 to block the second through holes and the socket sleeve. After the pin passes through the plug hole on the socket cover 42, the second through hole on the protective door cover, and the first through hole 34 of the pressure plate 35, it is inserted into the socket sleeve in the socket base 41. The protective door structure is modularly designed, easy to install and disassemble, convenient for maintenance and replacement, reduces the number of internal parts of the socket for easier management, and is suitable for automated assembly.

[0051] Preferably, the two ends of the baffle 421 are the first end and the second end, respectively.

[0052] 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, the second end of the baffle 421 includes the first fixing part, and the bottom of the pressure plate 35 includes the second fixing part; or the second end of the baffle 421 is integrally formed with the bottom of the pressure plate 35, the first end of the baffle 421 includes the first fixing part, and the back of the socket cover 42 includes the second fixing part.

[0053] 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, the second end includes the first fixing part, and the bottom of the pressure plate 35 includes the second fixing part; or, the second end of the baffle 421 is integrally formed with the bottom of the pressure plate 35, the second end includes the first fixing part, and the protective door cover includes the second fixing part.

[0054] The first and second fixing parts can also be used to prevent the socket cover 42 or the door cover from being installed backwards.

[0055] Alternatively, neither the first end nor the second end is integrally formed with the internal structure of the socket. Both the first end and the second end include the first fixing part, and two second fixing parts are arranged opposite each other inside the socket.

[0056] Furthermore, in one embodiment, the second fixing part includes a support block, which is disposed on one side of the first fixing part of the baffle 421. When the protective door 1 tilts to abut against the baffle 421 on one side, the baffle 421 is bent by force and transferred to the support block. This arrangement helps the support block to improve the fatigue service life of the baffle 421.

[0057] Preferably, at least one set of opposing second sidewalls 312 and fourth sidewalls 314 are provided on the pressure plate 35, and the protective door 1 is slidably mounted on the second sidewalls 312 and fourth sidewalls 314; as Figure 1 and Figure 12a As shown, the protective door 1 is provided with two sliding shafts 33 on both sides, and the second side wall 312 and the fourth side wall 314 are provided with two sliding grooves 32 that cooperate with the sliding shafts 33. The sliding groove 32 includes a vertical guide section 321 and an inclined guide section 322. The guide section 321 and the guide section 322 are bent and connected, and the included angle between them is an obtuse angle.

[0058] When the protective door 1 is in the first position, it is located within the guide section 321 and away from the guide section 322, preferably 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 located within the guide section 322 and away from the guide section 321, preferably at the end of the guide section 322 away from the guide section 321. When the protective door 1 slides on the guide end 321, it generates displacement in the first direction D1. When the protective door 1 slides on the guide section 322, it generates displacement in both the first direction D1 and the second direction D2.

[0059] Furthermore, the pressure plate 35 includes at least one protective door mounting groove 31, and the protective door 1 is slidably mounted in the protective door mounting groove 31. The protective door mounting groove 31 includes a first side wall 311, a second side wall 312, a third side wall 313, and a fourth side wall 314, with the first side wall 311 and the third side wall 313 facing each other, and the second side wall 312 and the fourth side wall 314 facing each other. Figure 12a A schematic diagram of the structure of the pressure plate 35 is shown.

[0060] Preferably, the width of the first through hole 11 is greater than the thickness of the baffle 421. The first surface of the baffle 421 is opposite to the first side 111 of the first through hole 11, and the second surface of the baffle 421 is opposite to the second side 112 of the first through hole 11. In a preferred embodiment, when the protective door 1 is in the first position, the first surface of the baffle 421 abuts against the first side 111 of the first through hole 11, the second surface is spaced apart from the second side 112, and the third side 113 abuts against the first side wall 311. When the protective door 1 is in the second position, the first surface of the baffle 421 is spaced apart from the first side 111 of the first through hole 11, the second surface abuts against the second side 112 of the first through hole 11, and the third side 113 is spaced apart from the first side wall 311. The gap between the third side 113 and the first side wall 311 corresponds to another pin hole.

[0061] 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.

[0062] Preferred, such as Figures 7-10 As shown, 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 a single pole insertion, 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.

[0063] Preferably, 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. Alternatively, the elastic element 2 is disposed between the pressure plate 35 and the protective door 1. One end of the elastic element 2 is installed on the bottom of the pressure plate 35, and the other end is installed on the back of the protective door 1. When the protective door 1 is in the first position, the elastic element 2 drives the protective door 1 to be tightly pressed against the back of the socket cover 42.

[0064] Furthermore, such as Figures 1-6 As shown, 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... 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.

[0065] Preferred, such as Figures 2-5 and Figure 12a As shown, when the protective door 1 is inserted by a single pole, the protective door 1 tilts, and at least one end of the protective door 1 abuts against the structure inside the socket, limiting the rotation angle of the protective door 1. The third side 113 includes at least one second extension 12, which protrudes from the third side 113 and extends away from the first through hole 11 along the length direction of the protective door 1. The pressure plate 35 is provided with a recessed clearance area 123 that cooperates with the second extension 12. The clearance area 123 is located on one or both sides of the first sidewall 311. The second extension 12 extends into the clearance area 123. When the protective door 1 moves vertically along the guide section 321, the second extension 12... 2. When the protective door 1 is located in the avoidance zone 123 and moves vertically along the avoidance zone 123, the second extension 12 moves vertically along the avoidance zone 123 and moves away from the avoidance zone 123. When the protective door 1 is in the second position, the second extension 12 is at least partially located in the avoidance zone 123. When the protective door 1 slides back and forth between the first position and the second position, the protective door 1 can be limited on the third direction D3 to improve the smoothness of the sliding of the protective door 1.

[0066] Furthermore, a first limiting structure is provided on one or both sides of the second extension 12 opposite to the first limiting structure, and a second limiting structure is provided on the pressure plate 35 to cooperate with the first limiting structure of the second extension 12 for limiting. Alternatively, a second limiting structure is provided on the protective door cover or socket cover 42 to cooperate with the first limiting structure of the second extension 12 for limiting. By providing the first and second limiting structures, when a single pole is inserted into the protective door 1, the protective door 1 tilts, and the first and second limiting structures abut against each other, limiting the rotation angle of the protective door 1 and ensuring that the protective door 1 always blocks the plug hole, thereby further optimizing the effect of preventing single pole insertion.

[0067] In this embodiment of the application, when the end of the protective door 1 furthest from the second extension 12 is subjected to force and sinks (e.g. Figure 9 and Figure 10 As shown), the second extension 12 is raised and abuts against the socket cover 42; when the end of the second extension 12 is subjected to force and sinks (as shown), Figure 7 and Figure 8 As shown), the second extension 12 abuts against the pressure plate 35, preventing the protective door 1 from continuing to rotate and avoiding the protective door 1 from rotating inside the pressure plate 35 and thus releasing the obstruction of the force-bearing end pin hole.

[0068] 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.

[0069] in, Figure 6 , Figure 8 and Figure 10 The first section of the socket of this application is shown in a cross-sectional view. The first section is a view after the socket is cut with the second boss 13 and the first groove 14 as the cutting parts and the plane containing the first direction D1 and the second direction D2 as the cutting surface. Figure 7 and Figure 9 This diagram shows a cross-sectional view of the socket of this application, where the second section is cut along the plane containing the first direction D1 and the second direction D2. Figure 13 This is a cross-sectional view of the plug inserted into the socket when the protective door 1 of this utility model is in the second position.
