Abstract
Description
Technical Field
[0001] This invention relates to a two-stage push-out plug module for power sockets and their applications. Background Technology
[0002] Travel sockets feature plugs compatible with different country and region socket standards. Due to size limitations, common travel sockets employ a retractable design, concealing these plugs within the socket housing. When in use, the plugs are extended using a corresponding push-button and linkage mechanism. However, since different plugs have specific shapes depending on their standards—for example, European standard plugs include a European standard socket and several prongs on the socket, plus an linkage mechanism outside the socket—this places high demands on the storage space of the socket housing, hindering the optimization and miniaturization of the socket's size. Summary of the Invention
[0003] Based on the background technology, this invention proposes a power socket and its application of a two-stage push-out plug module, which is achieved through the following technical means:
[0004] The two-stage push-out plug module of the present invention includes a housing and pins. The front end of the housing is a sleeve. The pins are hidden in the housing and pass through the housing through a through hole on the front end face of the sleeve or are stored in the housing. A travel groove with the same direction as the pins is provided on the housing. A lever block connected to the pins is provided in the travel groove. Pushing the lever block will cause the pins to move along the direction of the travel groove.
[0005] In one or more embodiments of the present invention, the housing is provided with a sliding seat, a guide rail and conductive plates corresponding to each pin. The sliding seat is mounted on the guide rail and can slide along the guide rail. The upper part of the sliding seat is provided with the toggle block. The pin is mounted on the sliding seat and each pin is provided with a contact electrode for electrical connection with the conductive plate. The front part of the conductive plate contacts the pin when the pin passes through the housing, and the rear part of the conductive plate is exposed outside the housing.
[0006] In one or more embodiments of the present invention, the two ends of the travel groove are respectively provided with a lever position, and the lever position is located on the same side of the travel groove axis; the sliding seat includes a sliding seat body and a transverse sliding block, a transverse sliding groove is provided on the upper part of the sliding seat body, a transverse sliding block is provided in the sliding groove, and an elastic element is provided at one end of the sliding groove to push the transverse sliding block to the other end of the sliding groove, and the lever is provided on the transverse sliding block.
[0007] In one or more embodiments of the present invention, the lower part of the sliding seat body is provided with a guide portion that cooperates with the guide rail, and the guide portion is mounted on the guide rail so that the sliding seat body can slide along the guide rail.
[0008] In one or more embodiments of the present invention, the sliding seat is further provided with a locking component, which cooperates with the locking positions located at both ends of the travel groove to limit the movement, and releases the limit when the toggle block is pushed away from the toggle block position.
[0009] In one or more embodiments of the present invention, the locking assembly includes a locking seat, an elastic element, and a locking block. The locking block is mounted on the locking seat and is pushed upward by the elastic element. The locking block is limited by locking positions located at both ends of the travel groove. The bottom of the transverse sliding block is provided with a downward pressing slope adapted to the locking block. When the transverse sliding block moves to the point where the downward pressing slope contacts the locking block, it forces the locking block to move downward, thereby causing the upper end of the locking block to move out of the locking position to unlock.
[0010] In one or more embodiments of the present invention, the locking seat is provided with a longitudinal limiting groove, and the two sides of the locking block are provided with claws embedded in the limiting groove. When the claws move to the top of the limiting groove, they abut against the end face of the groove to achieve limiting.
[0011] In one or more embodiments of the present invention, the pins include an L-pin, an N-pin, and an E-pin, and the rear end of each pin is respectively connected to an electrical contact member for electrical connection with a conductive sheet.
[0012] The power socket of the present invention includes a socket body and a two-section push-out plug module. The socket body is provided with a receiving groove for storing the plug module. The two-section push-out plug module has pivot shafts on both sides of its housing that cooperate with the groove wall of the receiving groove, so that the two-section push-out plug module can be flipped out of the receiving groove or put into the receiving groove around the pivot shaft. The receiving groove is provided with an electrical contact point, which connects with the rear part of the exposed conductive sheet when the two-section push-out plug module is flipped out of the receiving groove.
[0013] Compared with existing technologies, the advantages of this invention are: it cleverly utilizes the internal space of the socket to house the prongs that were originally located on the socket, and then pushes them out using a lever during use, greatly reducing the size of the plug module and facilitating the optimized design of the size and shape of travel sockets. Furthermore, considering the problem of prongs being easily pushed back in telescopic structures, this plug module is equipped with a locking structure linked to the lever. It unlocks simultaneously when the lever is moved out of the locking position and automatically locks when the lever reaches the locking position. This makes it convenient to use and prevents the prongs from being pushed back. Moreover, the structure is simple, easy to assemble, and reliable, exhibiting superior economy, technical sophistication, and practicality. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1 to 10 The following is a further description of the proposed solution:
[0025] See appendix Figure 1 and 2 The two-stage push-out plug module of the present invention includes a housing 1 and prongs 2. The front end of the housing 1 is a sleeve 11, and the sleeve 11 is connected to the rear end of the housing by a detachable connection structure. A connecting groove 100 is provided on the front end face of the rear end of the housing, and a connector 110 adapted to the connecting groove 100 is provided on the rear end face of the sleeve 11 for easy assembly. The prongs 2 are hidden in the housing 1 and pass through or are stored in the housing 1 through a through hole 10 on the front end face of the sleeve 11. A travel groove 3 in the same direction as the prongs 2 is provided on the housing 1. A lever 4 connected to the prongs 2 is provided in the travel groove 3. Pushing the lever 4 causes the prongs 2 to move along the direction of the travel groove 3. This structure cleverly utilizes the internal space of the sleeve to accommodate the prongs that were originally located on the sleeve. When in use, the prongs are pushed out by the lever, which greatly reduces the volume of the plug module and is beneficial to the optimized design of the size and shape of travel sockets.
[0026] For details, please see the appendix. Figures 3 to 9The plug 2 includes an L-pole plug, an N-pole plug, and an E-pole plug. The housing 1 is provided with a sliding seat 5, a guide rail 6, and conductive plates 7 corresponding to each plug 2. The sliding seat 5 is mounted on the guide rail 6 and can slide along the guide rail 6. The toggle block 4 is provided on the upper part of the sliding seat 5. The plug 2 is assembled on the sliding seat 5, and the rear end of each plug 2 is provided with an electrical contact member 21 for electrical connection with the conductive plate 7. The front part 701 of the conductive plate 7 contacts the electrical contact member 21 when the plug 2 passes through the housing. The rear part 702 of the conductive plate 7 is exposed outside the housing and serves as the electrical connection point between the plug module and the socket body. The two ends of the travel groove 3 are respectively provided with lever positions 31 and 32. The lever positions 31 and 32 are located on the same side of the axial direction of the travel groove 33. When the lever 4 is in the lever position 31, the pin 2 is completely retracted into the sleeve 11. When the lever 4 is in the lever position 31, the working section of the pin 2 is completely extended out of the sleeve 11. When switching modes, force is applied to push the lever 4 laterally away from the lever position 31 or 32, and then move within the travel groove 33. The sliding seat 5 includes a sliding seat body 51 and a transverse sliding block 52. A transverse sliding groove 53 is provided on the upper part of the sliding seat body 51. A transverse sliding block 52 is provided in the sliding groove 53. An elastic element 54 is provided at one end of the sliding groove 53 to push the transverse sliding block 52 to the other end of the sliding groove 53. The lever 4 is located on the transverse sliding block 52. The lower part of the sliding seat body 51 is provided with a guide part 511 that cooperates with the guide rail. The guide part 511 is mounted on the guide rail 6 so that the sliding seat body 51 can slide along the guide rail 6.
[0027] The sliding seat 5 is also provided with a locking component 55. The locking component 55 cooperates with the locking positions 331 and 332 located at both ends of the travel groove 33 to limit the movement, and releases the limit when the lever 4 is pushed away from the lever positions 31 and 32. The locking component 55 includes a locking seat 551, an elastic element 552 and a locking block 553. The locking block 553 is assembled on the locking seat 551 and is pushed upward by the elastic element 552. The locking block 553 cooperates with the locking positions 331 and 332 located at both ends of the travel groove 33 to limit the movement. The bottom of the transverse sliding block 52 is provided with a downward pressing slope 521 adapted to the locking block 553. The locking block 553 has a downward pressing slope 521 that matches the locking block 553. 21. The opposing contact slope 5531, as the transverse sliding block 52 moves laterally, the downward pressure slope 521 contacts the contact slope 5531 of the locking block 553, forcing the locking block 553 to move downward, thereby causing the upper end of the locking block 553 to move out of the locking positions 331 and 332 to unlock. In this embodiment, the upper end of the locking block 553 is a locking crossbar, and the locking positions 331 and 332 are grooves provided on the inner side of the housing that are adapted to the locking crossbar. The locking seat 551 is provided with a longitudinal limiting groove 5511, and the two sides of the locking block 553 are provided with claws 5532 embedded in the limiting groove 5511. When the claws 5532 move to the top of the limiting groove 5511, they abut against the end face of the groove to achieve limiting.
[0028] The two-stage push-out plug module of this invention cleverly utilizes the internal space of the socket to house the prongs, which were originally located on the socket. During use, the prongs are pushed out using a lever, significantly reducing the size of the plug module and facilitating the optimized design of the travel socket's size and shape. Simultaneously, considering the issue of prongs easily being pushed back in telescopic structures, this plug module is equipped with a locking structure linked to the lever. It unlocks simultaneously when the lever is moved away from the locking position and automatically locks when the lever reaches the locking position. Since the locking block is automatically forced downwards during the lever's lateral movement to release the latch, the user does not need to apply force, making it convenient to use and preventing the prongs from being pushed back. Furthermore, the structure is simple, easy to assemble, and reliable.
[0029] The two-section push-out plug module of this invention can be applied to travel socket products with push-out or flip-out structures. The following example uses a flip-out travel socket:
[0030] See appendix Figure 10The power socket of the present invention includes a socket body 8 and the aforementioned two-section push-out plug module. The socket body 8 is provided with a receiving groove 81 for storing the plug module. The housing 1 of the two-section push-out plug module is provided with pivot shafts 12 on both sides that cooperate with the groove wall of the receiving groove, so that the two-section push-out plug module can be flipped out of the receiving groove 81 or put into the receiving groove 81 around the pivot shaft 12. The receiving groove 81 is provided with an electrical contact point, which connects to the rear of the exposed conductive piece 7 when the two-section push-out plug module is flipped out of the receiving groove 81.
[0031] In use, first flip the socket 11 out of the receiving slot 81 to a vertical position. At this time, the conductive piece of the plug module is connected to the electrical contact point in the receiving slot 81. Then, move the lever 4 to push the pin 2 out of the socket 11. Since the pin 2 of the plug module is hidden inside the socket 11, the receiving slot 81 does not need to consider the reception of the pin 2, so the volume space is further reduced, allowing the socket body 8 to have a smaller size or allowing more design space on other parts of the socket body 8 besides the receiving slot 81.
[0032] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
