[0043] For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0044] Please refer to Figure 1 and Figure 2 A power strip according to an embodiment of the present invention includes: a shell 1, a socket 2, a conductive strip 3 and a jumper 4.
[0045] The surface of the housing 1 is provided with a socket 11. The socket 11 is used for inserting an external plug.
[0046] The socket 2 is arranged inside the housing 1, and the socket 2 is arranged corresponding to the socket 11. An external plug is inserted into the socket 2 through the socket 1111 and connected to the socket 2.
[0047] The conductive bar 3 is disposed inside the housing 1. In this embodiment, the conductive bar 3 is a copper bar.
[0048] Please refer to Figure 2 and Figure 7 The jumper 4 is arranged inside the housing 1 , and at least one socket 2 is connected to its corresponding conductive bar 3 via the jumper 4 .
[0049] Please refer to Figure 3 The semi-enclosed structure 5 is arranged inside the housing 1 and forms a groove. At least one socket 2 is arranged in the semi-enclosed structure 5. The semi-enclosed structure 5 has a partition 51. The partition 51 separates the socket 2 and the conductive bar 3 that is not connected to the socket 2. The partition 51 is also higher than the connection between the socket 2 and the jumper 4 corresponding to the socket 2, and / or the partition 51 is higher than the connection between the socket 2 and the conductive bar 3.
[0050] And / or refers to the situation where some sockets 2 are directly connected to the conductive bar 3, while some sockets 2 are connected to the conductive bar 3 via jumpers 4, and the partition 51 is higher than the connection between the socket 2 and the corresponding jumper 4. At the same time, the partition 51 is higher than the connection between the socket 2 and the conductive bar 3. In the case where only the socket 2 is directly connected to the conductive bar 3, the partition 51 is higher than the connection between the socket 2 and the conductive bar 3. In the case where the socket 2 is connected to the conductive bar 3 via jumpers 4, the partition 51 is higher than the connection between the socket 2 and the corresponding jumper 4.
[0051] The power strip of this embodiment includes a housing 1, sockets 2, conductive bars 3, jumpers 4, and a semi-enclosed structure 5. The semi-enclosed structure 5 semi-encloses the sockets 2. A partition 51 of the semi-enclosed structure 5 separates the sockets 2 from the conductive bars 3 not connected to them. Furthermore, the partition 51 is higher than where the sockets 2 connect to the conductive bars 3 or jumpers 4. While reducing the distance between the sockets 2, the partition 51 also ensures creepage distance between the sockets 2 and the surrounding conductive bars 3, thereby achieving a compact structure.
[0052] The partition 51 also protrudes laterally beyond the connection between the plug-in sleeve 2 and the corresponding jumper 4 .
[0053] Please refer to Figure 3 The horizontal direction refers to the length or width direction of the power strip. With such a structure, even if the height of the jumper 4 is different from the connection position between it and the socket 2, the creepage distance and electrical clearance between the socket 2, the jumper 4 and the conductive bar 3 can be ensured.
[0054] In this embodiment, the partition portion 51 extends along the extension direction of the conductive bar 3 toward both sides of the socket 2 , thereby protruding laterally from the connection between the socket 2 and the corresponding jumper 4 .
[0055] In this embodiment, the conductive bars 3 include a first conductive bar 31, a second conductive bar 32, a third conductive bar 33, and a fourth conductive bar 34, which are arranged parallel to each other and in sequence. In this embodiment, the first conductive bar 31, the second conductive bar 32, the third conductive bar 33, and the fourth conductive bar 34 are all parallel to the length direction of the housing 1 and arranged along the width direction of the housing 1.
[0056] The socket 2 includes a first socket 21 , a second socket 22 , a third socket 23 and a fourth socket 24 that are mated to form a plug.
[0057] In this embodiment, each socket 2 is applied to a three-phase four-hole socket. Since the three-phase four-hole socket has many parts such as the conductive bar 3, socket 2 and jumper 4, it is more difficult to reduce the distance between the sockets 2 and it is not easy to achieve a compact structure. Therefore, the compact structure of the three-phase four-hole socket is taken as an example.
[0058] At least a portion of the first socket 21 is located on and connected to the first conductive bar 31 . At least a portion of the second socket 22 is located on and connected to the second conductive bar 32 . The third socket 23 and the fourth socket 24 are located between the first conductive bar 31 and the second conductive bar 32 . The third socket 23 is connected to the third conductive bar 33 via a jumper 4 , and the fourth socket 24 is connected to the fourth conductive bar 34 via another jumper 4 .
[0059] The first conductive bar 31 is the ground wire, and the second conductive bar 32, the third conductive bar 33, and the fourth conductive bar 34 are all live wires. Since the first conductive bar 31 and the second conductive bar 32 are relatively close to the socket 2, the first socket 21 and the second socket 22 can be directly connected to the first conductive bar 31 and the second conductive bar 32.
[0060] The third conductive bar 33 and the fourth conductive bar 34 are relatively far apart, so a jumper 4 is provided between the third socket 23 and the fourth socket 24 for connection.
[0061] Separators 51 are provided between each of the first socket 21 , the second socket 22 , the third socket 23 , and the fourth socket 24 . Separators 51 are provided between the third socket 23 and the first conductive bar 31 and the second conductive bar 32 , respectively. Separators 51 are provided between the fourth socket 24 and the first conductive bar 31 and the second conductive bar 32 , respectively. The separators 51 are higher than the connecting portions 26 .
[0062] The provision of the partition 51 ensures electrical clearance and creepage distances between the sockets 2, and also ensures electrical clearance and creepage distances between the sockets 2 and the conductive bars 3 that are not connected thereto, such as between the third socket 23 and the first conductive bar 31, thereby making the structural design more compact.
[0063] Please refer to Figure 6 The first socket 21, the second socket 22, the third socket 23 and the fourth socket 24 have the same structure and all include a jacket portion 25 and a connecting portion 26. The jacket portion 25 is arranged at one end of the connecting portion 26. The jacket portion 25 is arranged corresponding to the socket 11. The connecting portions 26 of the first socket 21 and the second socket 22 are respectively connected to the first conductive bar 31 and the second conductive bar 32. The connecting portions 26 of the third socket 23 and the fourth socket 24 are respectively connected to the corresponding jumper 4.
[0064] An external plug is inserted into the socket 2 through the jack 11. The clamping portion 25 clamps the external plug, connecting the external plug to the socket 2. The connecting portion 26 connects the clamping portion 25 to the jumper 4, thereby electrically connecting the conductive bar 3, such as the third socket 23 and the fourth socket 24. Alternatively, the connecting portion 26 directly connects the conductive bar 3, such as the first socket 21 and the second socket 22.
[0065] In this embodiment, the connection portion 26 is connected by screws or rivets. In other embodiments, welding can also be used.
[0066] The socket 2 further includes a reinforcing plate, which is disposed on the connecting portion 26 to increase the strength of the connecting portion 26 .
[0067] Please refer to Figure 4 and Figure 5 The semi-enclosed structure 5 forms a first groove 52 with a first opening 53. The jacket portion 25 of the first socket 21 is disposed in the first groove 52. The first opening 53 is used for the connecting portion 26 of the first socket 21 to pass through. The connecting portion 26 of the first socket 21 is located on the first conductive bar 31.
[0068] The first slot 52 surrounds the first socket 21 on three sides. The connecting portion 26 extends from the first opening 53 and connects to the first conductive bar 31. This ensures electrical clearance and creepage distances between the first socket 21 and the nearby third socket 23, fourth socket 24, and second conductive bar 32.
[0069] The connecting portion 26 and the clamping portion 25 of the second socket 22 are both located on the second conductive bar 32 .
[0070] Isolators are provided between the second socket 22 and the first socket 21 , the third socket 23 and the fourth socket 24 , respectively, to ensure electrical clearances and creepage distances between the second socket 22 and the first socket 21 , the third socket 23 and the fourth socket 24 .
[0071] The distance between the second socket 22 and the third conductive bar 33 and the first conductive bar 31 is relatively large, so the electrical clearance and creepage distance can also be guaranteed. If the third conductive bar 33 is arranged closer, the electrical clearance and creepage distance can also be guaranteed by providing a separator 51.
[0072] The semi-enclosed structure 5 forms a second groove 54 having a second opening 55 . The third socket 23 is disposed in the second groove 54 . The second opening 55 allows the jumper 4 corresponding to the third socket 23 to pass through.
[0073] The second slot 54 surrounds the third socket 23 on three sides. The connecting portion 26 is also located in the second slot 54 . One end of the jumper 4 enters the second slot 54 from the second opening 55 and connects to the connecting portion 26 . The other end of the jumper 4 connects to the third conductive bar 33 .
[0074] The provision of the separator 51 ensures electrical clearance and creepage distance between the third socket 23 and the nearby first socket 21 , second socket 22 , fourth socket 24 , first conductive bar 31 , and second conductive bar 32 .
[0075] The semi-enclosed structure 5 forms a third groove 56 having a third opening 57 . The fourth plug socket 24 is disposed in the third groove 56 . The third opening 57 allows the jumper 4 corresponding to the fourth plug socket 24 to pass through.
[0076] The third slot 56 surrounds the fourth socket 24 on three sides. The connecting portion 26 is also located in the third slot 56 . The first end of the jumper 4 enters the third slot 56 from the third opening 57 and connects to the connecting portion 26 . The other end of the jumper 4 is connected to the third conductive bar 33 .
[0077] The third groove 56 and the second groove 54 are symmetrically arranged, and the second opening 55 and the third opening 57 are also symmetrically opened.
[0078] The provision of the separator 51 ensures electrical clearance and creepage distance between the fourth socket 24 and the nearby first socket 21 , second socket 22 , third socket 23 , first conductive bar 31 , and second conductive bar 32 .
[0079] The connecting portions 26 of the first plug sleeve 21 , the third plug sleeve 23 , and the fourth plug sleeve 24 are located on the same side of the jacket portion 25 .
[0080] With such a structure, the sockets 2 can be made more compact.
[0081] The connecting portion 26 of the second plug sleeve 22 is located on a side of the clamping portion 25 facing the third plug sleeve 23 or the fourth plug sleeve 24 .
[0082] In this embodiment, the connection portion 26 of the second socket 22 is located on the side of the jacket portion 25 facing the fourth socket 24 , so that the connection position of the connection portion 26 does not affect the position of the jacket portion 25 , thereby making the sockets 2 more compact.
[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
