This application claims the benefit of priority of Chinese Patent Application No. 2024100391827, filed Jan. 11, 2024, which is incorporated herein by reference.
The present disclosure relates to the technical field of electrical plugs, more particularly to a plug with a temperature-controlled circuit breaker.
At present, common electrical power cord plugs available on the market are manufactured by directly connecting two pins to a power cord (that is, a live wire and a neutral wire) and then molding by injection of PVC. A power plug includes pins, a support, and a lead. Each pin has one end connected to one end of the lead within the support, while another end of the lead is exposed out of the support for insertion into a power socket to interface with a power supply, where the power supply is fed to an electrical appliance through the lead. The support is configured to insulate each pin and insulate electrified parts from the outside world. To guarantee the safety of electricity usage, generally, power supply circuits and electrical appliances are provided with overload and short circuit protection mechanisms therein. Once a short circuit occurs, a main fuse of the power supply circuit will trip, or an internal protection circuit inside the electrical appliance will short circuit, which could affect other electrical appliances, and disrupt everyday work and life.
At present, common three-phase plugs have two specifications for ground wire pins. One is in a cylindrical shape and one is in a flat sheet shape, which are not interchangeable. Multiple plugs need to be carried during usage because each plug is made to only one specification. Particularly, for present plugs, when a lead end and a shell are assembled through a connection structure, an adhesive is further needed to adhere them together. If a plug is damaged, it can only be discarded rather than repaired, resulting in a waste of resources. Further, the plug and the socket can easily loosen from each other after a period of usage leading to poor contact, and can burn out the plug and the socket.
Therefore, the existing technology needs to be improved and further developed.

The technical scheme of the present disclosure is described below in conjunction with the drawings and embodiments.
As illustrated in
The overheat/overcurrent protection component includes a connecting terminal 3, a fixed contact piece 31, and a bimetallic strip 32. The connecting terminal 3 is fixedly connected to the fixed contact piece 31 by an insulated terminal 33. The bimetallic strip 32 has a first end fixedly connected to the fixed contact piece 31. The bimetallic strip 32 has a second end provided with a moving contact 34, and a static contact 35 is arranged on the connecting terminal 3. The live wire pin 21 and the neutral wire pin 22 are each fixedly connected to corresponding fixed contact pieces 31. A live wire and a neutral wire at the lead end 2 can each be connected to connecting terminals 3 of two overheat components respectively. The live wire at the lead end 2 is welded to the connecting terminal 3, forming a series connection with the live wire pin 21 by using the overheat/overcurrent protection component. Similarly, the neutral wire at the lead end 2 is welded to the connecting terminal 3, forming a series connection with the neutral wire pin 22 by using the overheat/overcurrent protection component. Once an electrical overload or short circuit occurs on the circuit between an electrical appliance, the plug, and a socket, particularly when poor contact and the like occur between the plug and the socket, or when an electrical spark, temperature rise, or the like occur at the contact area between the plug and the socket during use of the electrical appliance, the bimetallic strip 32 can respond quickly and deform, cutting off the path between the moving contact 34 and the static contact 35, thereby disconnecting the current flow to protect the plug main body 1 and the socket. Preferably, two sets of overheat/overcurrent protection components are arranged inside the plug main body 1, providing dual protection and improving safety.
A positive temperature coefficient (“PTC”) element 4 is bridged between the connecting terminal 3 and the bimetallic strip 32. The PTC element 4 has a far greater value of resistance than the bimetallic strip 32. In normal conditions, the PTC element 4 and the bimetallic strip 32 are equivalent to being in parallel connection, and the PTC element 4 does not activate due to a very low division voltage, hence does not generate heat. When poor contact results in high temperature and short circuit, the bimetallic strip 32 trips to cut off the path between the moving contact 34 and the static contact 35, enabling the PTC element 4 to receive a working voltage, and the PTC element 4 generates heat to maintain the thermal deformation state of the bimetallic strip 32. Therefore, the plug main body 1 needs to power off to reduce the temperature of the PTC element 4 before it can be reused, thereby implementing a power-off reset function and avoiding power supply circuit trips caused by an electrical appliance restarting before electrical issues can be resolved.
The moving contact 34 is welded onto the bimetallic strip 32 employing a molten material, or the static contact 35 is welded onto the connecting terminal 3 employing a molten material. The molten material can achieve a fusing effect. When the overheat/overcurrent protection component has a failure, the molten material on the moving contact 34 or the static contact 35 also fails, thereby causing the moving contact 34 and the static contact 35 to disengage and forcing the power off, protecting the socket, the electrical appliance, and the whole power supply circuit.
The main body 1 includes a shell 11 and at least one positioning module 12. The shell 11 is a hollow structure with an upper opening. Inside the upper opening of the shell 11 is provided positioning module 12, and the positioning module 12 comprises at least two constituent components which are removably connected, such as by snap-fitting. The constituent components are arranged symmetrically such that positioning module 12 forms a positioning opening 13. The lead end 2 defines a neck groove 24. The neck groove 24 is removably connected to the positioning opening 13, whereby the lead end 2 is fixed toward the upper opening of the shell 11. The shell 11 employs injection molding processes and has insulating properties, and is used to assemble the internal overheat/overcurrent protection component and circuit. The lead end 2 is first welded with the connecting terminal 3. The lead end 2 is positioned within the positioning module 12, which is placed about the neck groove 24. The shell 11 defines plug holes 15 on a lower end surface. The live wire pin 21, the neutral wire pin 22, and the ground wire pin 23 are aligned with plug holes 15 on shell 11, and then are installed through the upper opening of the shell 11. The positioning module 12 defines a fixing hole 16, and the positioning module 12 can be fixedly connected to the shell 11 by a fastener, such as a bolt, and the fixing hole 16, thereby allowing quick assembly.
The positioning module 12 is provided with a plurality of limit blocks 14. The live wire pin 21, the neutral wire pin 22, and the ground wire pin 23 are each provided with a folding plate 25. The shell 11 defines plug holes 15 on a lower end surface thereof. The live wire pin 21, the neutral wire pin 22, and the ground wire pin 23 insert through corresponding plug holes 15. The limit blocks 14 on the positioning module 12 are connected to and abut against the folding plates 25 on the live wire pin 21, the neutral wire pin 22, and the ground wire pin 23 respectively. The limit blocks 14 abut against the folding plates 25, limiting any movement of live wire pin 21, the neutral wire pin 22, and the ground wire pin 23 within shell 11, preventing any loosening of the pins, increasing the stability of the overheat/overcurrent protection components and prolonging the service life of the product.
As illustrated in
To remove the ground wire pin 23, the ground wire pin 23 is pushed upward along a vertical direction, wherein the conductive pole 233 drives the first disc 237 upward via the slide rod 236, and the first disc 237 squeezes against the first locking structure to unlock the same, thereafter the second disc 235 can slide from the assembly groove 231, and the ground wire pin 23 can be removed from the limit block 14.
As illustrated in
At least one second locking structure is located between the ground wire pin 23 and the shell 11. The second locking structure includes a second chute 110, a second guide rod 111, and a columnar locking tab 112. The second chute 110 is arranged within the shell 11 and adjacent to the conductive pole 233. The conductive pole 233 defines a first locking groove 239 connected to the second chute 110. Inside the second chute 110 is the second guide rod 111 and an elastic element. The second guide rod 111 has a first end fixedly connected to the second chute 110. The columnar locking tab 112 is slidably arranged on a second end of the second guide rod 111. The elastic element abuts against the columnar locking tab 112, whereby the columnar locking tab 112 is removably connected to the first locking groove 239. Preferably, the conductive pin 234 penetrates through the first disc 237, and the conductive pin 234 is rotatable relative to the conductive sleeve 232. In this way, the ground wire pin 23 can be removed by rotating the ground wire pin 23 so that the conductive pole 233 presses against the columnar locking tab 112, subjecting the columnar locking tab 112 to a pressure and columnar locking tab 112 thereby slides from the first locking groove 239 to retract into the second chute 110, allowing the second locking structure to unlock the ground wire pin 23. Thereafter, the ground wire pin 23 can slide upward to unlock the first locking structure.
At least one assistant pairing structure is arranged between the positioning module 12 and the lead end 2 and couples the positioning module 12 to the lead end 2. The assistant pairing structure includes a lock box 120 containing a driving slider 121, a third guide rod 122, and a wedged driving head 123. The lock box 120 is arranged adjacent to an upper end of the positioning module 12. The third guide rod 122 is fixedly arranged inside the lock box 120. The driving slider 121 is slidably connected to the third guide rod 122, and the lock box 120 has an upper end surface defining a maintenance opening. Inside the neck groove 24 is defined a second locking groove 241. One end of the lock box 120 is provided with a locking head 124. The locking head 124 is inserted into neck groove 24 in a removably connected state, and the locking head 124 is provided with an elastic fastener 125. The wedged driving head 123 is fixedly connected to the driving slider 121 by a synchronous connecting rod 126. Inside the lock box 120 is positioned an elastic element, and the elastic element abuts against the driving slider 121, whereby the elastic fastener 125 is fitted about the wedged driving head 123. The assistant pairing structure is used for quick assembly of the positioning module 12 and the lead end 2. The positioning module 12 clamps the lead end 2, and the neck groove 24 removably connects with the positioning opening 13. The locking head 124 on the lock box 120 is inserted into the neck groove 24. The elastic element drives the wedged driving head 123 to press against the elastic fastener 125, whereby the elastic fastener 125 is removably connected into the second locking groove 241, such that the positioning module 12 and the lead end 2 are quickly connected for convenient assembly into the shell 11. Of course, when a part inside the shell 11 needs repair, as the driving slider 121 has defined thereon a depression corresponding to the maintenance opening of lock box 120, a small tool can be used to engage the depression via the maintenance opening to separate the positioning module 12 from the lead end 2 by pushing the driving slider 121 away from the locking head 124, whereby the synchronous connecting rod 126 drives the wedged driving head 123 away from the elastic fastener 125. Thereafter, the elastic fastener 125 can be reset and disengaged from the second locking groove 241, allowing the positioning module 12 to separate from the lead end 2.
At least one assistant assembly structure is arranged between the positioning module 12 and the shell 11. The assistant assembly structure includes a steel ball 127, a rubber block 128, and an elastic element in a third locking groove 129 defined within the positioning module 12. The third locking groove 129 has a first end extending through an outer wall of the positioning module 12 to form an opening. The shell 11 has an inner wall, and defined thereon is a limit recess 113. The rubber block 128 and the steel ball 127 are inserted into the opening of the first end of the third locking groove 129. Inside the third locking groove 129 is provided an elastic element, and the elastic element drives the rubber block 128 and the steel ball 127 toward the limit recess 113. The positioning module 12 and the lead end 2 form an integrated structure which is then inserted into the upper opening of the shell 11, whereby the steel ball 127 is paired with the limit recess 113, the elastic element drives an outer end of the rubber block 128 against an inner wall of the shell 11, and the steel ball 127 is clamped into the limit recess 113, such that the vertical positioning is locked between the positioning module 12 and the shell 11 and the manner of locking is resilient. When a sufficiently large vertical force is applied to the positioning module 12 or the shell 1, the vertical force can overcome the force of the elastic element, disengaging the steel ball 127 from the limit recess 113, thereby facilitating subsequent disassembly and maintenance of the positioning module and the shell.
The third locking groove 129 has a second end provided with an adjusting screw 114 which can modify the vertical force required to disengage the steel ball 127, and thus the force required to disengage the positioning module 12 and the shell 11 from each other. The adjusting screw 114 is in threaded connection with the third locking groove 129. Inside the third locking groove 129 is an adjusting press plate 115. The adjusting screw 114 has one end connected to the adjusting press plate 115. The elastic element is arranged between the adjusting press plate 115 and the rubber block 128. Further, a friction force between the rubber block 128 and the shell 11 as well as a fit strength between the steel ball 127 and the limit recess 113 can be modified by the adjusting screw 114. The adjusting screw 114 can be rotated to drive the adjusting press plate 115 toward or away from the steel ball 127, thereby changing the force of the elastic element. It is understood that the elastic element is a spring.
The above are merely preferred embodiments of the present disclosure. Any equivalent changes or modifications made according to the construction, features, and principles within the patent scope of the present disclosure are intended to be included within the patent scope of the present disclosure.
