Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of track socket, specifically relates to a track socket five hole adapter. BACKGROUND

[0002] In the field of electrical equipment connection today, with the continuous improvement of people's demand for electrical convenience and space utilization flexibility, the track socket system has been widely used, and the track socket adapter plays a key role.

[0003] The traditional track socket adapter, from its structure, is mainly composed of an adapter main body, contacts and jacks. The adapter main body is usually made of plastic or metal material to build a shell frame to carry and protect the internal key components. The carefully laid circuit board inside is the "brain" of the entire adapter operation, coordinating power distribution and many other functions, while the contacts, as a bridge connecting the track socket and the adapter main body, are usually made of copper or nickel, a good conductive material, to ensure that the power supply can be smoothly introduced from the track socket to the adapter main body, thereby realizing stable power supply. The common jack forms are diverse, covering two-hole and three-hole sockets, and some have innovatively integrated USB interfaces, fully meeting the power and charging needs of various electrical equipment.

[0004] However, the existing track socket adapter has significant drawbacks in the design of internal circuit conduction connection. At present, the conduction of internal circuit mainly depends on copper parts, which usually need multiple copper parts to be connected to each other to build an electrical connection path. In the actual production and assembly process, due to the large number of copper parts, their fixing and assembly process in the adapter shell is extremely complex, consuming a lot of manpower and time cost. And those copper parts that are not fixed like a "time bomb" can move unexpectedly at any time due to slight external force impact, vibration and other factors. Once the copper parts are displaced, not only will the original circuit connection stability be damaged, causing poor contact, but also the electrical equipment will be interrupted and abnormal, and serious electrical safety accidents may occur due to contact point sparking, posing a great threat to the user's life and property safety.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0044] The following references Figures 1-12 The utility model is described as follows:

[0045] The utility model discloses a track socket five-hole adapter which comprises a shell 1 (the shell 1 is cylindrical, and the shell 1 is made of plastic), the plastic material has good insulation performance, can effectively prevent the electric shock danger, and guarantees the use safety. Meanwhile, the cylindrical design is not only relatively beautiful in appearance, but also is more reasonable in space utilization, and installation and layout on the track socket are facilitated. The shell 1 serves as the basic framework of the whole adapter, provides installation and support space for various internal components, and plays a role in protecting the internal structure from external interference and damage.

[0046] The cover body 2 is rotationally connected to the opening side of the shell 1 and is made of plastic.

[0047] The cover 2 is composed of a fixed cover 201 and a movable cover 202, the fixed cover 201 is circular, the movable cover 202 is annular, and the fixed cover 201 is fixedly connected with the shell 1 through a connecting column. In the opening direction of the shell 1, the fixed cover 201 is arranged in a spaced manner with the shell 1, and the movable cover 202 is located between the fixed cover 201 and the shell 1. In the opening direction of the shell 1, the movable cover 202 is fixedly arranged. In the circumferential direction of the shell 1, the movable cover 202 is rotatably arranged. This design enables the movable cover 202 to flexibly move in a circumferential direction without changing its axial position, thereby providing an operation basis for subsequent control of the on-off of the circuit.

[0048] The bottom of the inner side of the shell 1 is provided with a mounting seat 3 (the mounting seat 3 is made of plastic), and the plastic material also ensures good insulation, thereby ensuring that no electric leakage occurs between the electrically connected parts. The mounting seat 3 is fixedly connected with the shell 1, and the fixed connection enables the mounting seat 3 to be stably located at the bottom of the inner side of the shell 1, thereby providing reliable support for the electrically connected parts.

[0049] The jack 4 is arranged on the fixed cover 201 and is a part into which the plug pin is inserted. The jack 4 provides an access channel for the plug, so that the plug pin can smoothly enter the inside of the adapter and contact the electrically connected parts, thereby realizing the connection of the power supply.

[0050] The first electrically connected part 5 and the second electrically connected part 6 are arranged on the mounting seat 3 and correspond to the jack 4. When the plug pin is inserted from the jack 4, the first electrically connected part 5 and the second electrically connected part 6 can be contacted, thereby forming an electrical connection and providing a power supply for the electrical equipment.

[0051] The inside of the mounting seat 3 is provided with the third electrically connected part 7 and the fourth electrically connected part 8 corresponding to the first electrically connected part 5 and the second electrically connected part 6 respectively, and the third electrically connected part 7 and the fourth electrically connected part 8 are directly injection molded in the mounting seat 3. This injection molding process enables the electrically connected parts to be closely combined with the mounting seat, thereby ensuring the stability of the position of the electrically connected parts, reducing the problem of poor contact caused by looseness, and improving the reliability and safety of the adapter.

[0052] The first electrically connected part 5 and the second electrically connected part 6 are respectively provided with the first contact 51 and the second contact 61, and these contacts are key parts for realizing electrical connection and can ensure the stable transmission of current.

[0053] One end of the third electrically connected part 7 extends into the shell 1 to form the third contact 71, and the third contact 71 is arranged in correspondence with the first contact 51. The other end of the third electrically connected part 7 extends to the lower side of the shell 1, and this layout provides a reasonable path for the subsequent circuit conduction. The fifth electrically connected part 9 is also included, the middle part of the fifth electrically connected part 9 is in electrical contact with the third contact 71 (the fifth electrically connected part 9 and the third contact 71 always maintain an electrical contact state), and the fifth electrically connected part 9 can be left-right tilted. When the fifth electrically connected part 9 moves to the left, the left end of the fifth electrically connected part 9 can be in electrical contact with the first contact 51, so that the first electrically connected part 5 and the third electrically connected part 7 are conducted through the fifth electrically connected part 9.

[0054] One end of the energizing component 4 8 extends into the housing 1 to form contact 4 81, which corresponds to contact 2 61. The other end of the energizing component 4 8 extends to the lower side of the housing 1. This layout provides a reasonable path for subsequent circuit conduction. It also includes an energizing component 6 10, the middle of which is in electrical contact with contact 4 81 (energizing component 6 10 and contact 4 81 maintain electrical contact at all times). The energizing component 6 10 can be tilted left and right. When the energizing component 6 10 moves to the right, its right end can make electrical contact with contact 2 61, thus connecting energizing component 2 6 and energizing component 4 8.

[0055] The movable cover 202 is equipped with operating levers 11 corresponding to the five electrical connectors 9 and 10, respectively. One end of the operating lever 11 is fixedly connected to the cover body 2, and the other end of the operating lever 11 is abutted against the middle of the five electrical connectors 9 and 10, respectively. When the movable cover 202 is rotated, the operating lever 11 rotates accordingly, driving the five electrical connectors 9 and 10 to tilt left and right, thereby controlling the on / off state of the circuit.

[0056] The middle part of contact 5 (9) maintains constant electrical contact with contact 3 (71), and contact 5 (9) can be tilted left and right. When contact 5 (9) moves to the left, its left end can make electrical contact with contact 1 (51), thus connecting contact 1 (5) and contact 3 (7) through contact 5 (9). The situation with contact 6 (10) is similar to that of contact 5 (9). Its middle part maintains constant electrical contact with contact 4 (81), and it can be tilted left and right. When contact 6 (10) moves to the right, its right end can make electrical contact with contact 2 (61), thus connecting contact 2 (6) and contact 4 (8). This design controls the circuit's on / off state through the tilting of the contact, providing a certain degree of flexibility and reliability.

[0057] The operating lever 11 is mounted on the movable cover 202, with one end fixedly connected to the cover body 2 and the other end abutting against the middle of the electrical connectors 9 and 10 respectively. When the movable cover 202 is rotated, the operating lever 11 rotates accordingly. Since the operating lever 11 abuts against the electrical connectors 9 and 10, the rotation of the operating lever 11 drives the electrical connectors 9 and 10 to tilt left and right, thereby controlling the circuit's on / off state. This method of controlling the circuit's on / off state by rotating the movable cover is simple and convenient to operate, allowing users to easily turn the power on or off as needed, thus improving ease of use.

[0058] On / off control principle:

[0059] Initial state of the circuit: In the initial state, energizing component 5 (9) and energizing component 6 (10) are in electrical contact with contact 3 (71) and contact 4 (81) respectively. However, the left end of energizing component 5 (9) is not in electrical contact with contact 1 (51), and the right end of energizing component 6 (10) is not in electrical contact with contact 2 (61). At this time, there is no conduction between energizing component 1 (5) and energizing component 3 (7), and between energizing component 2 (6) and energizing component 4 (8), and the entire circuit is in an open state.

[0060] Conductive control: When the movable cover 202 is rotated, the operating rod 11, which is fixedly connected to the movable cover 202, rotates accordingly. The other end of the operating rod 11 abuts against the middle of the electrical connector 5 9 and the electrical connector 6 10. As the operating rod 11 rotates, it drives the electrical connectors 5 9 and 6 10 to tilt left and right. When the electrical connector 5 9 moves to the left, its left end can make electrical contact with contact 1 51, thereby connecting the electrical connectors 1 5 and 3 7 through the electrical connector 5 9; similarly, when the electrical connector 6 10 moves to the right, its right end can make electrical contact with contact 2 61, thereby connecting the electrical connectors 2 6 and 4 8, thus realizing the conduction of the entire circuit, enabling the plug to draw power after being inserted into the socket.

[0061] Disconnection control: Rotate the movable cover 202 in the reverse direction. The operating lever 11 will cause the five-connector 9 and the six-connector 10 to move in the opposite direction. The five-connector 9 will separate from the first contact 51, and the six-connector 10 will separate from the second contact 61. The circuit will be disconnected again, and the power supply to the electrical appliance will stop.

[0062] A limiting groove 12 is provided on the inner sidewall of the upper end of the housing 1 along its circumference. A limiting post 13 corresponding to the limiting groove 12 is provided on the cover 2. The limiting post 13 cooperates with the limiting groove 12 to limit the rotation angle of the cover 2. By adopting the above technical solution, the angle of forward and reverse rotation of the movable cover 202 is limited, so that the operating rod 11 is always kept in contact with the electrical contact 9 and the electrical contact 10.

[0063] In the five-hole adapter of the track socket, the stable operation of connector 9 and connector 10 is crucial for the reliable switching of the circuit. To ensure that these two connectors can tilt left and right only under the control of the operating lever 11 as required by the design, avoiding unnecessary displacement and shaking, and thus ensuring the stability and safety of the circuit connection, a specific positioning structure was designed.

[0064] Both the fifth and sixth electrical connectors (9 and 10) have protruding positioning parts (14) on both sides of their central portion. These positioning parts (14) are key structures for achieving precise positioning and stable operation of these two electrical connectors. Their protruding design allows the electrical connectors to effectively cooperate with other components, restricting their movement in specific directions and thus ensuring the accuracy of their operation.

[0065] Mounting base 3 is provided with connecting seats for connecting electrical components 9 and 10 respectively. The connecting seats include two connecting plates 15, and electrical components 9 and 10 are located between the two connecting plates 15. This design provides a relatively fixed space for the electrical components, restricts the left and right displacement of the electrical components in the horizontal direction, and prevents the electrical components from moving excessively laterally during operation, thereby ensuring the correct connection and contact between the electrical components and other components.

[0066] The connecting plate 15 is provided with a positioning groove 16, and the positioning parts 14 of the five electrical connectors 9 and 10 are precisely located in the positioning groove 16. The cooperation between the positioning groove 16 and the positioning parts 14 further enhances the positioning effect of the electrical connectors. The positioning groove 16 provides a precise movement track for the positioning parts 14, so that during the left and right tilting of the electrical connectors, the positioning parts 14 can only move along the trajectory of the positioning groove 16, avoiding swaying and offset of the electrical connectors in other directions, and ensuring the stability and consistency of the electrical connectors' operation.

[0067] By adopting the above technical solution, the five-connector 9 and the six-connector 10 are confined between the two connecting plates 15, the positioning part 14 is confined in the positioning groove 16, the lower sides of the five-connector 9 and the six-connector 10 are confined by the mounting base 3, and the upper sides of the five-connector 9 and the six-connector 10 are confined by the operating lever 11. Thus, only the five-connector 9 and the six-connector 10 are allowed to tilt left and right under the operation of the operating lever 11.

[0068] The five connecting parts 9 and 10 are constrained not only horizontally by the two connecting plates 15, but also vertically by other components. The lower side of the connecting parts is constrained by the mounting base 3, which provides a stable support surface to prevent downward movement or falling. The upper side of the connecting parts is constrained by the operating lever 11, which abuts against the connecting parts, controlling their left and right tilting while also providing a certain limit to prevent excessive upward movement.

[0069] Through the coordinated action of the aforementioned components, contact parts 5 (9) and 6 (10) are strictly confined to specific ranges of motion. Only when operated by lever 11 can the contact parts tilt left or right. This precise motion control allows the contact parts to accurately make and separate from other contacts, thereby reliably controlling the circuit's continuity. This avoids problems such as poor circuit contact and short circuits caused by the arbitrary movement of the contact parts, improving the reliability and safety of the five-hole track socket adapter.

[0070] The bottom of the housing 1 has a mounting hole 17, which forms the basis for the installation and fit of the entire bottom structure. An extension post 18 extends downwards from the center of the mounting base 3. The extension post 18 provides a passage for the three electrical connectors 7 and 8, allowing them to extend from inside the housing to the outside for electrical connection. The design of the extension post 18 ensures the orderly arrangement and stable installation of the electrical connectors, preventing them from shaking or shifting during use and affecting the stability of the electrical connection.

[0071] Two extension strips 19 extend backward from the lower end of the extension post 18. The other ends of the connecting parts 7 and 8 pass through the extension post 18 and extend out from the ends of the two extension strips 19 to form connecting parts 20. When the adapter is installed on the track, the two connecting parts 20 make electrical contact with the neutral wire and live wire conductive strip in the track, respectively, thereby transferring the electricity on the track to the plug to power external electrical equipment. This design ensures reliable power transmission and is a key element for the adapter to function.

[0072] The inner wall of the mounting hole 17 is provided with an annular limiting ring 21, and it also includes an annular rotating seat 22. An annular connecting ring 23 is provided on the outer wall of the upper end of the rotating seat 22. The connecting ring 23 is located between the limiting ring 21 and the mounting seat 3, and its outer diameter is equal to the diameter of the mounting hole 17. The connecting ring 23 is constrained between the limiting ring 21 and the mounting seat 3, and it rotatably engages with the mounting hole 17, allowing the rotating seat 22 to rotate. This structural design allows the connecting ring 23 to rotate within a certain range, enabling the rotating seat 22 to rotate. The engagement of the limiting ring 21 and the connecting ring 23 ensures both the rotational flexibility of the rotating seat 22 and restricts its axial position, preventing the rotating seat 22 from dislodging from the mounting hole during use and ensuring structural stability.

[0073] The rotating base 22 facilitates the installation and removal of the adapter on the track. By rotating the rotating base 22, the position of the other end of the extension bar 19 and the electrical connectors 7 and 8 can be controlled, thereby enabling the connection and disconnection of the adapter from the track.

[0074] The lower side of the rotating base 22 is provided with a mounting slide 24 along its radial direction. The mounting slide 24 is inserted into the slide groove on the track and forms a sliding fit. The center of the mounting slide 24 is provided with a slot 25 corresponding to the extension column 18. The extension column 18 is located in the slot 25. This design allows the mounting slide 24 to maintain a relatively stable positional relationship with the extension column 18 during sliding, avoiding mutual interference.

[0075] The mounting slide 24 has receiving grooves 26 on both sides. When the rotating base 22 rotates, the other ends of the two extension bars 19 and the third and fourth electrical connectors 7 and 8 can respectively enter the two receiving grooves 26. When the other ends of the two extension bars 19 and the third and fourth electrical connectors 7 and 8 are in the two receiving grooves 26, the mounting slide 24 is inserted into the slide groove in the track, and the mounting slide 24 can also be pulled out from the slide groove in the track. This facilitates the installation and removal of the adapter. When the other ends of the two extension bars 19 and the third and fourth electrical connectors 7 and 8 are removed from the two receiving grooves 26, the mounting slide 24 cannot be inserted into the slide groove in the track, and the mounting slide 24 cannot be pulled out from the slide groove in the track. This acts as a locking mechanism, ensuring that the adapter is securely installed on the track during normal use and will not accidentally fall off, improving the safety and stability of use.

[0076] The housing 1 contains a locking component that restricts the rotation of the rotating base 22. The main function of the locking component is to restrict the rotation of the rotating base 22, thereby ensuring the stability and safety of the adapter during normal use. By locking the rotating base 22, problems such as poor contact between the contact part and the conductive strip in the track or the adapter falling off the track due to accidental rotation of the adapter can be prevented.

[0077] The locking assembly includes a locking seat 31, which has a U-shaped structure. A connection hole 32 is provided on the side wall of the housing 1, and the opening of the locking seat 31 faces the connection hole 32. (The U-shaped structure provides a stable track for the moving block 33, allowing it to reciprocate along the opening direction of the locking seat 31. Simultaneously, the locking seat 31 also provides a base for mounting and supporting components such as the spring 35.)

[0078] The locking seat 31 is connected to a movable block 33, which can reciprocate along the opening direction of the locking seat 31. A pressing part 34 is provided on the outer side of the movable block 33. The pressing part 34 is connected in the connecting hole 32. The pressing part 34 provides an operation interface for the user, who can drive the movable block 33 to move by pressing the pressing part 34.

[0079] A spring 35 is provided between the middle of the movable block 33 and the locking seat 31. The spring 35 has an elastic restoring force. Under normal conditions, the spring 35 is in a certain extended state, which applies an outward force to the movable block 33, keeping the movable block 33 in a specific position, thereby ensuring that the locking assembly is in the locked state. When the user presses the pressing part 34, the spring 35 is compressed and stores elastic potential energy; when the user releases the pressing part 34, the elastic potential energy of the spring 35 is released, pushing the movable block 33 to reset.

[0080] The rotating base 22 is provided with an upwardly protruding first locking protrusion 36, and the mounting base 3 is provided with a hole for the first locking protrusion 36 to pass through. The first locking protrusion 36 is a key part of the rotating base 22 and the locking assembly. It can interact with other parts of the locking assembly when the rotating base 22 rotates to limit the rotation of the rotating base 22.

[0081] The inner side of the movable block 33 is provided with an L-shaped locking hook 37. One end of the locking hook 37 is connected to the movable block 33, and the other end of the locking hook 37 is provided with a second locking protrusion 38. The design of the locking hook 37 allows the second locking protrusion 38 to move as the movable block 33 moves. The first locking protrusion 36 and the second locking protrusion 38 cooperate with each other, and when they are in the cooperated state, they can prevent the rotating seat 22 from rotating.

[0082] By adopting the above technical solution, under the action of spring 35, the first locking protrusion 36 and the second locking protrusion 38 are in a locked state of mutual engagement. Since the mounting slide 24 is located in the groove on the track, the housing 1 cannot rotate at this time. When the pressing part 34 is pressed, the moving block 33 moves inward, the spring 35 is compressed, and the engagement of the first locking protrusion 36 and the second locking protrusion 38 is separated. At this time, the housing 1 can rotate, and the other ends of the two extension bars 19 and the electrical connectors 7 and 8 enter the two receiving grooves 26. At this time, the mounting slide 24 is inserted into the groove in the track, and the mounting slide 24 can also be pulled out from the groove in the track. When the pressing part 34 is released, the spring 35 returns to its original position, and the first locking protrusion 36 and the second locking protrusion 38 re-enter the locked state.

[0083] Locked status:

[0084] Under the action of spring 35, the moving block 33 is in the outward position. At this time, the first locking protrusion 36 and the second locking protrusion 38 cooperate with each other and are in a locked state. Since the mounting slide 24 is located in the groove on the track, after the rotating seat 22 is locked, the housing 1 cannot rotate. The adapter is firmly installed on the track, and the electrical contact part maintains stable electrical contact with the conductive strip in the track, ensuring normal power transmission.

[0085] Unlocking process:

[0086] When the user presses the pressing part 34, the external force overcomes the elastic force of the spring 35, causing the moving block 33 to move inward, and the spring 35 is compressed. As the moving block 33 moves, the second locking protrusion 38 on the locking hook 37 also moves, disengaging from the engagement with the first locking protrusion 36. At this time, the rotating seat 22 is no longer restricted and can rotate freely. The user rotates the rotating seat 22, causing the other ends of the two extension bars 19 and the electrical connectors 7 and 8 to enter the two receiving slots 26. At this time, the mounting slide bar 24 can be inserted into the slide groove in the track or pulled out of the slide groove in the track, facilitating the installation and removal of the adapter.

[0087] Relocked:

[0088] When the user releases the pressure on the pressing part 34, the elastic restoring force of the spring 35 causes the moving block 33 to move outward and reset. As the moving block 33 resets, the second locking protrusion 38 re-engages with the first locking protrusion 36, re-enters the locked state, the rotation of the rotating seat 22 is restricted again, and the adapter returns to a stable operating state.

[0089] In summary, this locking assembly, through the synergistic effect of its various structural components, effectively controls the rotation of the rotating base 22, ensuring the safe and stable use of the five-hole adapter for the track socket.
