Description

Technical Field

[0001] This utility model relates to the field of plug technology, and in particular to a push-pull plug with a partition for protection. Background Technology

[0002] Currently, traditional push-pull plugs use a sliding mechanism to control the extension and retraction of the prongs. However, this presents several safety hazards in practical use: The sliding hole (used for push-button operation) is susceptible to accidental insertion of external metal objects (such as pins, screws, etc.), which can then contact the internal conductive plates or mainboard, leading to short circuits or electric shock. This risk increases significantly, especially when the plug is placed in humid, dusty, or environments with many metal objects. Existing protective designs often employ split baffles or complex sealing structures, which not only increase the number of parts and assembly difficulty but also allow foreign objects to remain in the gap between the baffle and the housing, resulting in insufficient protective reliability. Therefore, preventing metal foreign objects from entering the product's internal cavity through the sliding hole and causing electric shock is a pressing issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to provide a push-pull plug with a partition for protection, which aims to solve the problem of how to prevent metal foreign objects from entering the inner cavity of the product through the sliding hole and causing electric shock, thereby reducing the number of parts, lowering the failure rate, and improving product stability.

[0004] To achieve the above objectives, this utility model provides a push-pull plug with a partition for protection, comprising:

[0005] The housing includes a fixed bracket and a main board, and has a track groove on a first side and two insertion holes on a second side; the bottom of the track groove has a sliding hole; the first side and the second side are perpendicular to each other.

[0006] Two conductive plates are fixed to both sides of the fixing bracket to connect to the positive and negative input interfaces of the motherboard, respectively.

[0007] The movable bracket is provided with a push button, two contact plates and two pins; the push button is used to slide along the sliding hole so that the two pins extend or retract in the two sockets respectively, thereby causing the contact plates to abut or disengage from the corresponding conductive plates;

[0008] A partition, one end of which is fixed to the housing and completely covers the sliding hole relative to the vertical projection of the first side.

[0009] In a preferred embodiment, the push button includes a push block and a connecting rod; the push block is disposed in the track groove, and the surface on the side away from the sliding hole is not higher than the first side surface; one end of the connecting rod is connected to the push block, and the other end passes through the sliding hole and is connected to the movable bracket.

[0010] In a preferred embodiment, the push button further includes two hooks located on the side of the connecting rod away from the push block; the movable bracket has two locking holes adapted to the hooks; the hooks pass through the corresponding locking holes to engage with a predetermined position on the movable bracket to connect the connecting rod to the movable bracket.

[0011] In a preferred embodiment, the movable bracket has a through hole located between the two locking holes; the partition plate passes through the through hole.

[0012] In a preferred embodiment, the pusher is circular, and the two ends of the track groove are semicircular and adapted to the pusher.

[0013] In a preferred embodiment, the housing has at least one conduit on the inner wall corresponding to the first side, and the conduit has a clearance hole along its length; the movable support has a guide block adapted to the conduit, and one end of the guide block away from the movable support passes through the clearance hole and is provided with a limiting block; the limiting block is located inside the conduit and its outer diameter is larger than the gap of the clearance hole.

[0014] In a preferred embodiment, the movable bracket has two mounting holes, and a metal sleeve is fitted onto the bottom of each of the prongs; the metal sleeve is rotatably connected to the corresponding mounting hole.

[0015] In a preferred embodiment, one end of the conductive piece has a circular hole, and the other end is bent vertically to form an insert; the circular hole is fitted onto the outer surface of the metal sleeve; the insert is used to abut against the corresponding conductive piece.

[0016] In a preferred embodiment, a limiting groove is provided at one end of the mounting hole near the insertion hole, and the shape of the limiting groove and the insertion hole are both adapted to the rotation range of the pin.

[0017] This utility model provides a push-pull plug with a protective partition. By fixing the partition to the housing and ensuring its vertical projection completely covers the sliding hole, a physical isolation barrier is formed. This ensures that when the push button moves within the sliding hole, the partition always blocks the hole, preventing foreign metal objects from entering the internal cavity. This prevents foreign metal objects from contacting the internal conductive sheet or main board through the sliding hole, eliminating the risk of electric shock and short circuits. Furthermore, the integrated design of the partition and housing reduces the number of parts, lowers the failure rate, and improves product stability. It also simplifies mold development and assembly processes, reducing production costs. Attached Figure Description

It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0030] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0031] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0032] In this embodiment of the invention, a push-pull plug 100 with a partition is provided for insertion into a socket to allow current input to an external power source, thereby providing power to electronic devices. Different plugs, such as US, EU, UK, Japanese, Chinese, and Australian plugs, can be provided to improve the product's applicability. Specifically, this invention primarily targets US and Australian plugs.

[0033] like Figures 1-8 As shown, the push-pull plug 100 with partition protection includes: a housing 10, two conductive plates 20, a movable bracket 30, and a partition 40.

[0034] Specifically, the housing 10 is generally rectangular in shape, and has a fixing bracket 11 and a main board 12 inside. The housing 10 has a track groove 101 on its first side A and two insertion holes 102 on its second side B. The track groove 101 is formed by recessing inward at a predetermined position on the first side A of the housing 10. A sliding hole 103 is formed at the bottom of the track groove 101, connecting the inside and outside of the housing 10.

[0035] Two conductive plates 20 are fixed to both sides of the mounting bracket 11 for connecting to the positive and negative input interfaces of the motherboard 12. The motherboard 12 is used to rectify and rectify the external AC power to output a suitable current to external electronic devices. It should be noted that the implementation principle and specific structure of the motherboard 12 in converting external power into power suitable for electronic devices can be found in existing technology and will not be repeated here. In this embodiment, a clamping structure 21 is provided at a predetermined position for each conductive plate 20.

[0036] In this embodiment, combined with Figures 6-8 As shown, the movable bracket 30 is equipped with a push button 31, two electrical contact pieces 32, and two pins 33. The two electrical contact pieces 32 and the two pins 33 are electrically connected respectively.

[0037] The push button 31 is used to slide along the sliding hole 103, so that the two prongs 33 extend or retract in the two sockets 102 respectively, thereby causing the contact piece 32 to abut against or disengage from the corresponding conductive piece 20. Here, the working state is defined as the two prongs 33 extending from the two sockets 102 to their maximum stroke, and the storage state is defined as the two prongs 33 being completely retracted into the housing 10. It should be noted that the first side A and the second side B are arranged perpendicularly, so that when the user pushes the push button 31 along the plane of the first side A, the prongs 33 will rise and fall in a direction perpendicular to the second side B.

[0038] Specifically, the push button 31 includes a push block 311 and a connecting rod 312. The push block 311 is disc-shaped and located within the track groove 101, and will not enter the housing 10 through the sliding hole 103. Further, the two ends of the track groove 101 are semi-circular to fit the push block 311. One end of the connecting rod 312 is connected to the push block 311, and the other end passes through the sliding hole 103 to connect to the portion of the movable bracket 30 located within the housing 10. In this embodiment, the surface of the push block 311 away from the sliding hole 103 is not higher than the first side surface A, so that the push block 311 is basically flush with the first side surface A, and the overall appearance is not obtrusive, making it simpler and more aesthetically pleasing. At the same time, compared with the usually more protruding push button structure on the market, it is less likely to get tangled with keys, data cables, etc. in a bag, thus making it easier to store.

[0039] Furthermore, the push button 31 also includes two hooks 313 located on the side of the connecting rod 312 away from the push block 311. Correspondingly, the movable bracket 30 has two locking holes 301 that are adapted to the hooks 313. The hooks 313 pass through the corresponding locking holes 301 to engage with a predetermined position on the movable bracket 30, so as to detachably connect the connecting rod 312 to the other parts of the movable bracket 30.

[0040] In this embodiment of the invention, the movable bracket 30 has two mounting holes 302. A metal sleeve 331 is fitted onto the bottom of each pin 33. The metal sleeve 331 is rotatably connected to the corresponding mounting hole 302, so that the two pins 33 are arranged in parallel or at an obtuse angle, which can adapt to the regulations of different countries and regions, thereby improving the applicability of this product.

[0041] The contact piece 32 is elongated, with a circular hole 321 at one end that matches the metal sleeve 331, and the other end bent vertically upward to form a plug 322. The circular hole 321 fits onto the outer surface of the metal sleeve 331, ensuring electrical connection between the pin 33 and the contact piece 32 regardless of the angle to which the metal sleeve 331 is rotated. The plug 322 abuts against the clamping structure 21 of the corresponding conductive piece 20. That is, when the pin 33 is in the working state, the plug 322 is inserted into the clamping structure 21.

[0042] Furthermore, a limiting groove 303 is formed at one end of the mounting hole 302 near the insertion hole 102. The shapes of the limiting groove 303 and the insertion hole 102 are adapted to the rotation range of the pin 33. The limiting groove 303 restricts the rotation range of the pin 33, ensuring that the pin 33 can only rotate within this range. Correspondingly, the shape of the insertion block 322 is also adaptively expanded to accommodate the rotation of the pin 33.

[0043] Combination Figures 3-5 As shown, the partition 40 is elongated and fixed at one end to the housing 10 to form an integral structure, which facilitates processing. The vertical projection of the partition 40 relative to the first side A completely covers the sliding hole 103, thereby forming a physical isolation barrier. When the pusher 311 moves within the sliding hole 103, the partition 40 always blocks the sliding hole 103, blocking the path of metal foreign objects into the inner cavity of the housing 10, thereby preventing metal foreign objects from contacting the internal conductive sheet 20 or the main board 12 through the sliding hole 103, and eliminating the risk of electric shock and short circuit.

[0044] The movable support 30 has a through hole 304. The through hole 304 is located between two locking holes 301. The partition 40 passes through the through hole 304, so that the partition 40 does not obstruct the movement of the movable support 30.

[0045] In some embodiments, the housing 10 has at least one conduit 13 on the inner wall corresponding to the first side A. In this embodiment, there are two conduits 13, respectively located on the left and right sides of the sliding hole 103. The conduit 13 has a clearance hole 131 along its length, which is strip-shaped. The movable support 30 has a guide block 34 adapted to the conduit 13. The guide block 34 is strip-shaped, and one end away from the movable support 30 passes through the clearance hole 131 and has a limiting block 341. The limiting block 341 is spherical, located inside the conduit 13, and its outer diameter is larger than the gap of the clearance hole 131, so that the limiting block 341 can only slide along the conduit 13 and will not disengage, thereby providing guidance for the lifting and lowering of the movable support 30 and preventing the movable support 30 from lateral movement during lifting and lowering. The clearance hole 131 is designed to prevent obstruction of the sliding of the middle part of the guide block 34.

[0046] In summary, the push-pull plug 100 with partition protection provided by this utility model forms a physical isolation barrier by fixing the partition 40 to the housing 10 and ensuring its vertical projection completely covers the sliding hole 103. This ensures that when the push button 31 moves within the sliding hole 103, the partition 40 always blocks the sliding hole 103, preventing metal foreign objects from entering the inner cavity of the housing 10. This prevents metal foreign objects from contacting the internal conductive sheet 20 or the main board 12 through the sliding hole 103, eliminating the risk of electric shock and short circuit. Furthermore, the integrated design of the partition 40 and the housing 10 reduces the number of parts, lowers the failure rate, and improves product stability. It also simplifies mold development and assembly processes, reducing production costs.

[0047] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
