Description

Technical Field

[0001] The present invention relates to a power electrode connection mechanism, a socket and an electrical connection coupler having the same. Background Art

[0002] A current rotary conductive electrical connection coupler mainly includes a plug and a socket (as shown in Figure 1A ). After the plug is inserted into the socket, the plug needs to be rotated by a certain angle in a certain direction to a specified position before the plug electrodes (such as 201') on the plug can be completely electrically connected to the socket electrodes (such as including power electrodes 11' and 12' and a ground electrode 13') on the socket 50', so as to achieve a safe power-on connection. However, for such an electrical connection coupler, when the plug is not rotated in place, a part of the plug electrodes (such as pins) on the plug is in contact (but not completely) with the socket electrodes (such as socket sleeves) on the socket, which is likely to generate a large resistance. Such a virtual contact is not only likely to cause heating, but also likely to cause the air between the pin and the live socket sleeve to break down to form an arc and emit sparks, thereby leading to the occurrence of faults and even possibly causing safety accidents. Therefore, there is an urgent need for a new type of electrical connection coupler that can overcome the above functional defects. Summary of the Invention

[0003] The object of the present invention is to provide an electrical connection coupler, its socket and a power electrode connection mechanism. Through the additional contact mechanism of the power electrode connection mechanism, it can start conducting instantly when the plug rotates in place and disconnect and stop conducting instantly when the plug rotates away, thereby making the product safer and more reliable.

[0004] To achieve the above object, the present invention provides a power electrode connection mechanism, which is characterized in that it is installed in a socket. The power electrode connection mechanism includes: a power electrode having a first contact; a rotating mechanism rotatably installed and capable of rotating between a first rotation position and a second rotation position; a sliding mechanism linked to the rotating mechanism and capable of sliding between a first sliding position and a second sliding position. The sliding mechanism has a second contact corresponding to the first contact, and the second contact is electrically connected to the live wire or neutral wire of the power supply. Wherein, when the rotating mechanism is in the first rotation position, the sliding mechanism is in the first sliding position, and the second contact is disconnected from the first contact; when the rotating mechanism is in the second rotation position, the sliding mechanism is in the second sliding position, and the second contact is in conductive contact with the first contact.

[0005] In an embodiment of the present invention, the power electrode connection mechanism further includes: a fixed upper cover; a fixed lower cover, which is assembled with the fixed upper cover to form an accommodation space, and the power electrode, the rotation mechanism, and the sliding mechanism are accommodated in the accommodation space; the rotation mechanism is rotatably installed through a rotation installation portion thereon and a rotation installation hole correspondingly provided on the fixed upper cover and / or the fixed lower cover; the sliding mechanism is slidably installed on the fixed upper cover and / or the fixed lower cover through a sliding spring and is in cooperative linkage contact with the rotation mechanism.

[0006] In an embodiment of the present invention, the power electrode includes a conductive contact portion that is in conductive contact with a power plug pin of a plug, and a part of the power electrode is bent downward to form a bent portion, and the first contact is provided on the bent portion; and the fixed upper cover further has a power electrode installation portion for assembling the power electrode.

[0007] In an embodiment of the present invention, one end of the rotation mechanism has a dial block, which is correspondingly arranged with respect to the conductive contact portion of the power electrode, and the dial block remains in contact with the power plug pin when the plug rotates between a first rotation position and a second rotation position; the other end of the rotation mechanism is in cooperative linkage contact with one end of the sliding mechanism, the other end of the sliding mechanism is slidably installed in cooperation with the sliding spring, and the second contact is provided on the other end of the sliding mechanism; when the plug rotates forward along a rotation direction to the first rotation position, the power plug pin starts to contact the dial block of the rotation mechanism, and at this time the rotation mechanism is in the first rotation position, the sliding mechanism is in the first sliding position, and the second contact is disconnected from the first contact; when the plug rotates forward from the first rotation position to the second rotation position, the power plug pin is in complete conductive contact with the conductive contact portion of the power electrode, and at this time the rotation mechanism rotates to the second rotation position, the sliding mechanism slides to the second sliding position, and the second contact is in conductive contact with the first contact; when the plug leaves the second rotation position and rotates backward toward the first rotation position, the second contact is disconnected from the first contact, and the sliding mechanism slides from the second sliding position toward the first sliding position under the push of the sliding spring, and the rotation mechanism rotates from the second rotation position toward the first rotation position through the linkage of the sliding mechanism.

[0008] In an embodiment of the present invention, the sliding mechanism is connected to a wiring terminal through a flexible wire and is electrically connected to the live wire or the neutral wire of the power supply through the wiring terminal.

[0009] In an embodiment of the present invention, the sliding mechanism is an L-shaped slider, which includes a vertical portion and a horizontal portion. The second contact is disposed on the vertical portion, the sliding spring is mounted corresponding to the vertical portion, and the flexible wire is connected to the horizontal portion.

[0010] To achieve the above object, the present invention further provides a socket, characterized in that the socket includes the power electrode connection mechanism as described above. Among them, the first contact of the power electrode connection mechanism is in conductive contact with the second contact when a plug rotates forward to a second rotation position, and the socket is instantaneously conductively connected to the plug; when the first contact of the power electrode connection mechanism rotates backward and leaves from the second rotation position, it is disconnected from the second contact, and the socket is instantaneously disconnected from the plug.

[0011] In another embodiment of the present invention, the socket includes two of the power electrode connection mechanisms and a ground electrode. The second contact of one of the power electrode connection mechanisms is connected to the live wire of the power supply, the second contact of the other power electrode connection mechanism is connected to the neutral wire of the power supply, and the ground electrode is connected to the ground wire of the power supply.

[0012] In another embodiment of the present invention, the power electrodes of the power electrode connection mechanism and the ground electrode are socket structures.

[0013] To achieve the above object, the present invention further provides an electrical connection coupler, characterized in that it includes a plug and the socket as described above.

[0014] Through the additional contact mechanism of the power electrode connection mechanism of the present invention, when the plug and the socket rotate to a predetermined position (such as the second rotation position), the contacts can be instantaneously contacted to start conduction, and when the plug rotates away from the predetermined position, the contacts can be instantaneously disconnected and non-conductive, thereby ensuring safety and reducing the occurrence of faults.

[0022] As Figure 2A , Figure 2B shown, the electrical connection coupler 300 of a preferred embodiment of the present invention includes a plug 200 and a socket 100. Among them, the plug 200 can be rotated, for example, by a predetermined angle (such as 60°, but the present invention is not limited thereto) from an initial position along the R direction in the figure to a conductive position. After the pins on the plug 200 are inserted into the socket 100, they can be rotated to the conductive position and electrically connected to the power electrodes and ground electrodes in the socket 100. In addition, the plug 200 also has a positioning block (not shown in the figure) and a cooperating unlocking button 204. When the plug 200 is in the conductive position, the positioning block pops out of the plug and is restricted by a positioning opening to fix the plug 200 in the socket 100, so that the pins on the plug 200 can be kept in full contact with the power electrodes and ground electrodes on the socket 100, making the plug 200 in a safe use state. When it is necessary to loosen the plug, the unlocking button 204 can be pressed to make the positioning block retract into the plug 200, thereby releasing the positioning between the plug 200 and the socket 100. In this way, the plug 200 can be directly pulled out, or the plug 200 can be rotated in the reverse direction to the initial position and then pulled out.

[0023] As Figure 2B shown, with reference to Figure 3, the socket 100 of the present invention has socket electrodes 10, which may include, for example, two power supply electrodes 11 and 12 respectively connected to the live wire and the neutral wire of the power supply, and one ground electrode 13 connected to the ground wire of the power supply. The two power supply electrodes 11 and 12 can be respectively in conductive contact with the two power supply pins 201 and 202 of the plug, and the ground electrode 13 can be in conductive contact with the ground pin 203 of the plug. In particular, for each of the power supply electrodes 11 and 12 of the present invention, a power supply electrode connection mechanism 20a and 20b is respectively provided. Each power supply electrode connection mechanism may include, for example, a power supply electrode having a first contact, a rotatable rotation mechanism, and a slidable sliding mechanism having a second contact. The rotation mechanism is rotatably mounted and can rotate between a first rotation position and a second rotation position. The sliding mechanism is linked to the rotation mechanism and can slide between a first sliding position and a second sliding position. The second contact is correspondingly arranged with the first contact and is electrically connected to the live wire or the neutral wire of the power supply. Wherein, when the rotation mechanism is in the first rotation position, the sliding mechanism is in the first sliding position, and the second contact is disconnected from the first contact; when the rotation mechanism is in the second rotation position, the sliding mechanism is in the second sliding position, and the second contact is in conductive contact with the first contact.

[0024] The power supply electrode connection mechanism of the present invention will be described in detail below mainly taking the power supply electrode connection mechanism 20a correspondingly arranged with the power supply electrode 11 as an example.

[0025] As Figures 4 - 5 shown, with reference to Figure 2B , in the present invention, the power supply electrode connection mechanism 20a includes a power supply electrode 11 having a first contact 111, a rotatable rotation mechanism 23, and a slidable sliding mechanism 24 having a second contact 241. The power supply electrode 11 includes a conductive contact portion 113 in conductive contact with the power supply pin (such as 201) of the plug, and a part of the power supply electrode 11 is bent downward to form a bent portion 112, and the first contact 111 is arranged on the bent portion 112.

[0026] The rotating mechanism 23 is rotatably mounted through a rotating mounting portion 231 thereon, and one end thereof has a dial block 231, which is arranged corresponding to the conductive contact portion 113 of the power supply electrode 11, and the dial block 231 always remains in contact with the power supply pin 201 when the plug 200 rotates between a first rotation position and a second rotation position. The other end of the rotating mechanism 23 is in cooperative linkage contact with one end of the sliding mechanism 24, the other end of the sliding mechanism 24 is slidably mounted in cooperation with a sliding spring 242, and the second contact 241 is arranged on the other end of the sliding mechanism 24.

[0027] In the present invention, the sliding mechanism 24 may be, for example, an L-shaped slider, which includes a vertical portion and a horizontal portion. Among them, the second contact 241 is arranged on the vertical portion, and the sliding spring 242 is mounted corresponding to the vertical portion. Preferably, the sliding mechanism 24 is connected to a terminal 27 through a flexible wire (such as a soft copper wire) 25, and is electrically connected to the live wire or neutral wire of the power supply through the terminal 27. In this embodiment, one end of the flexible wire 25 is connected to the horizontal portion of the L-shaped slider, and the other end is connected to the horizontal portion of an L-shaped connector 26, and the vertical portion of the L-shaped connector 26 is inserted into the terminal 27 and is electrically connected to the live wire or neutral wire of the power supply inserted into the terminal 27.

[0028] In this embodiment, the power supply electrode connection mechanism 20a further includes a fixed upper cover 21 and a fixed lower cover 22. The fixed lower cover 22 is assembled with the fixed upper cover 21 to form a receiving space 210 (see Figure 2B ), and the power supply electrode 11, the rotating mechanism 23, and the sliding mechanism 24 are received in the receiving space 210. Among them, the rotating mechanism 23 can be rotatably mounted through the rotating mounting portion 231 thereon and the rotating mounting hole 213 (see Figure 2B ) correspondingly arranged on the fixed upper cover 21 and / or the rotating mounting hole 223 (see Figure 2B ) on the fixed lower cover 22. The sliding spring 242 can be mounted through a spring mounting groove (not marked in the figure) correspondingly arranged on the fixed upper cover 21 and / or a spring mounting groove (not marked in the figure) on the fixed lower cover 22, so that the sliding mechanism (such as an L-shaped slider) can be slidably mounted on the fixed upper cover and / or the fixed lower cover and is in cooperative linkage contact with the rotating mechanism 23. In this embodiment, the fixed upper cover 21 further has a power supply electrode mounting portion 211 for assembling the power supply electrode 11 in cooperation.

[0029] As Figure 4 shown, with reference to Figure 3 andFigures 2A - 2B When the plug 200 rotates forward in a rotation direction R to a first rotation position, the power plug pin 201 starts to contact the block 241 of the rotation mechanism 23. At this time, the rotation mechanism 23 is in a first rotation position, the sliding mechanism 24 is in a first sliding position, and the second contact 241 is disconnected from the first contact 111. When the plug 200 rotates forward from the first rotation position to a second rotation position (i.e., the so-called "rotation in place"), as Figure 4 shown, at this time, the power plug pin 201 is in full conductive contact with the conductive contact portion 113 of the power electrode 11, and at this time, the rotation mechanism 23 rotates to a second rotation position along Figure 4 the F1 direction in Figure 4 , the sliding mechanism 24 slides to a second sliding position along

[0030] the F2 direction in Figure 5 shown, and the second contact 241 is in conductive contact with the first contact 111. At this time, the plug and the socket are instantaneously conductively connected. Figure 3 and Figures 2A - 2B As shown in Figure 4 , when the plug 200 leaves the second rotation position and rotates backward toward the first rotation position (i.e., rotates in the R' direction in Figure 4 ), at this time, the second contact 241 and the first contact 111 will be instantaneously disconnected from contact. At this time, the plug and the socket are instantaneously disconnected from power, and the sliding mechanism 24 can slide from the second sliding position toward the first sliding position along Figure 4 the F3 direction in

[0031] under the push of the sliding spring 242, and the rotation mechanism 23 can rotate from the second rotation position toward the first rotation position along

[0032] the F4 direction in Figure 2B shown through the linkage of the sliding mechanism. Figure 3 ).

[0033] Continue to refer to Figure 2B, in the present invention, the socket 100 may further include, for example, a lower housing 50, an upper cover 60, and a decorative panel 70. Among them, the protective cover 30 can be installed between the upper cover 60 and the lower housing 50. There is also an installation post 51 at the center position of the lower housing 50, and the protective cover 30 is pivotally installed by mating the installation hole 32 thereon with the installation post 51. In other embodiments, an insulating plate 40 may be provided between the protective cover 30 and the socket electrode 10, and the insulating plate 40 can also be pivotally installed through the installation post 51, and corresponding chutes (not marked in the figure) are provided on the insulating plate 40 for the pins on the plug to be inserted therein and slide along it from the initial position to the conductive position.

[0034] In the present invention, the socket electrode 10 may be, for example, a socket structure. Among them, the corresponding power supply electrodes 11 and 12 can be installed in cooperation with the power supply electrode installation part 211 on the fixed upper cover 21 of the corresponding power supply electrode connection mechanism, and the ground electrode 13 can be installed in a terminal washer in a terminal 131 and fixed by a wiring screw. The ground electrode 13 can be installed in the corresponding electrode installation groove on the lower housing 50 and be restricted by it. And corresponding to the power supply electrodes 11, 12 and the ground electrode 13, corresponding socket springs 15 can be respectively arranged on both the inner and outer sides thereof to be in contact with them, so as to ensure reliable electrical connection between the socket electrode 10 and the pins 201, 202, 203 on the plug 200. Corresponding to the power supply electrodes 11, 12 and the ground electrode 13, the outer socket springs 15 can be installed through sliders 14 respectively, and the sliders 14 can be installed in cooperation with the installation grooves 54 correspondingly arranged on the lower housing 50; the inner socket springs 15 can be installed through spring installation grooves with an arc-shaped bottom surface formed by further extending the corresponding electrode installation grooves.

[0035] Continue to refer to Figure 2B , preferably, a slider 34 may be further provided at the position corresponding to the jack 31 on the back of the protective cover 30, and it can be slidably installed in the corresponding slider installation groove on the protective cover 30 through a slider spring 35. Among them, when the pin of the plug 200 is inserted from the jack 31, the slider 34 will be pushed open to expose the chute on the insulating plate 40, so that the pin can be inserted into the chute and rotated from the initial position to the conductive position along the chute. When the plug is not inserted, the slider 34 closes the jack 31 under the reset action of the slider spring 35, so as to prevent pollutants such as dust from falling into the socket through the jack 31 and causing poor contact.

[0036] After the socket is assembled, the upper cover 60 and the lower housing 50 can be fixed by assembly screws. A decorative plate 70 can be further installed on the upper cover 60 by installation screws to make the appearance of the socket more beautiful. Markings can also be provided on the socket, which can indicate the usage method of the socket or other warning marks, etc., which are not limitations to the present invention.

[0037] Continuing to refer Figure 2B , in the present invention, the socket 100 can also have an automatic return mechanism, which can be, for example, a tension spring 33. There can be two tension springs 33, which are diagonally arranged at two opposite corner positions of the upper cover 60. One end of each tension spring 33 is installed on the upper cover 60, and the other end is installed on the protective cover 30 through a tension spring mounting post. Among them, the automatic return mechanism can provide a reset force to reset the plug 200 that has not been rotated to the conductive position (i.e., the second rotation position) to the initial position. Thus, during the rotation of the plug, if the plug is not rotated in place, the protective cover 30 will be reset to the initial position under the action of the automatic return structure.

[0038] In the present invention, the automatic return mechanism can also include a shock pad 63, which can be installed on the upper cover 60 through a mounting groove and can be made of TPU material to protect the protective cover 30 and the upper cover 60 from being damaged due to excessive rebound impact force of the tension spring 33.

[0039] Preferably, as Figure 2B shown, in the present invention, a top post 28 is also movably installed on the lower housing 50 of the socket 100 through a top post spring 281. The top post 28 can move up and down along the insertion direction of the plug. After installation, the positioning portion (not marked in the figure) above the top post 28 passes through the through hole on the insulating plate 40 and can cooperate with the positioning groove (not marked in the figure) provided on the side of the protective cover 30 for positioning. Among them, when the plug is not inserted, the positioning portion of the top post 28 cooperates with the positioning groove on the protective cover 30 for positioning to limit the rotation of the protective cover 30 and ensure that the socket is in the initial position. When the plug is inserted into the socket, the grounding pin 203 (see Figure 3 ) on the plug is inserted downward into the socket. When it is inserted until the lower part of the grounding electrode 13 contacts the contact portion (not marked in the figure) below the top post 28, the grounding electrode 13 will drive the top post 28 to move downward until the positioning portion of the top post 28 disengages from the positioning groove of the protective cover 30 (i.e., the plug is inserted in place). At this time, the plug can be rotated, and thus the rotation of the protective cover 30 can be driven by the rotation of the plug. During the downward insertion of the plug, if the grounding electrode 13 is not inserted downward in place (i.e., the positioning portion of the top post 28 does not completely disengage from the positioning groove of the protective cover 30), the plug will be restricted and cannot be rotated.

[0040] During the use of the electrical connection coupler of the present invention, after the plug is inserted into the socket (when not powered on), the plug is rotated by a certain angle to the conductive position (i.e., rotated in place, for example, it can be the second rotation position). Then, the first contact on the power electrode of the socket makes conductive contact with the second contact on the power electrode connection mechanism, and only then is the conduction established. When the plug is rotated away from the conductive position instantaneously, the first contact and the second contact are instantaneously disconnected, and at this time, there is no conduction. In this way, the problems of heat generation and sparks caused by virtual contact can be effectively avoided. Moreover, by setting an automatic return mechanism (such as a tension spring) in the socket, when in use, if the user does not rotate the plug to the specified position (such as the conductive position), the plug will be forcibly pulled back to the initial position (i.e., the position where the plug is just inserted into the socket) under the action of the restoring force of the tension spring, thus avoiding the occurrence of virtual connection. Therefore, the present invention greatly improves the functional defects of traditional sockets (small-current plugs and sockets), and has safe operability, reliable connectivity, and stable usability.

[0041] The above has specifically shown and described the exemplary embodiments of the present invention. It should be understood that the present invention is not limited to the disclosed embodiments. On the contrary, the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
