Description

Technical Field

[0001] This utility model relates to the field of household electrical appliances technology, and in particular to a series conductive copper sheet structure. Background Technology

[0002] Sockets are an indispensable household appliance in people's daily lives. Most electrical appliances use sockets, and as people's living standards improve, the number of electrical appliances in their homes will increase, and the number of times plugs are plugged into sockets will also increase.

[0003] In a standard socket, the copper contacts at both ends are bent to form a U-shaped connector. The top copper contacts of the U-shaped connector, along their edges, form... Figure 2 As shown, the socket copper piece is installed on the socket 11. The socket 11 is provided with a slot 111. The socket copper piece includes a copper piece 101. One end of the copper piece 101 is bent to form a U-shaped plug 102. The other end of the copper piece 101 is also bent to form a U-shaped plug 102. The inner wall of the slot 111 is provided with multiple limiting blocks 112. When the plug 102 deforms, it abuts against the multiple limiting blocks 112, but does not engage with the limiting blocks 112. Therefore, when the structure of the plug 102 is fixed for a long time, it cannot undergo large deformation. At this time, the abutting effect between the plug 102 and the limiting blocks 112 is reduced, and there is a possibility that the U-shaped plug will disengage from the slot in the socket, causing the socket to be unable to be properly plugged in.

[0004] In addition, the top of the connector 102 is provided with at least two curved copper strips for clamping the plug electrode 12. The curved structure makes the copper strips elastic, and the two copper strips bend towards each other. When the external plug electrode 12 is inserted into the U-shaped connector 102, the two copper strips deform elastically, thus pressing the plug electrode 12 tightly and preventing poor contact. However, the copper strips of sockets on the market can become loose after repeated insertion and removal, especially in the neutral and live wire connectors of three-prong sockets. This can easily cause poor contact between the plug electrode 12 and the copper strips, leading to short circuits, open circuits, and even fires. The specific reason is that the elastic deformation of the copper strips cannot be restored after repeated insertion and removal, resulting in an increased distance between the two copper strips, making it impossible for them to fit tightly against the plug electrode 12, thus causing short circuits and open circuits. Utility Model Content

[0005] The purpose of this utility model is to provide a series conductive copper sheet structure to solve the problems of copper sheets in sockets on the market becoming loose after repeated plugging and unplugging, and the U-shaped connector coming out of the socket slot.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A series conductive copper sheet structure, wherein both ends of the series conductive copper sheet are U-shaped connectors formed by bending, and each U-shaped connector has a first copper sheet edge on its top opposite sides, and the two first copper sheets are bent toward the inside of the U-shaped connector to form an arc surface structure.

[0008] The U-shaped connector has at least one slot on each of its opposite sides. When the plug is inserted, the minimum distance between the two first copper pieces along their edges is equal to the minimum distance between the two opposite slots.

[0009] Preferably, a copper plate is provided on the bottom outer wall of the slot to increase the contact area with the plug electrode plate.

[0010] Preferably, the first copper sheet is integrally formed with the slot along its edge.

[0011] Preferably, the slot is an arc-shaped structure formed by folding the two ends of the series conductive copper sheet, and the first copper sheet is welded along the edge to the top of the slot.

[0012] Preferably, the third side of the U-shaped connector is provided with a second copper strip edge, and the second copper strip edge bends toward the inside of the U-shaped connector.

[0013] Preferably, a power connection piece is provided at the middle position of the copper sheet, and the power connection piece is bent to one side and forms a 90° angle with the copper sheet.

[0014] Preferably, the power connector has a through hole for mounting bolts.

[0015] Preferably, at least one auxiliary plate is provided on the outer side of the power connection piece, and the auxiliary plate is bent to one side and forms a 90° angle with the power connection piece.

[0016] Preferably, the copper sheet has a long groove in the middle, and the bottom of the groove protrudes from one side of the middle of the copper sheet.

[0017] Preferably, the two ends of the groove are close to the two U-shaped connectors, and the shape of the groove is rectangular or elliptical.

[0018] Compared with the prior art, this utility model has the following advantages: This utility model securely installs the U-shaped connector in the socket slot by interlocking the slot with the limiting block inside the socket slot, preventing displacement. Furthermore, the minimum distance between the two opposing slots is exactly equal to the minimum distance between the edges of the two first copper pieces when the plug is inserted. This minimum distance is also the thickness of the plug electrode. Even when the edges of the two first copper pieces cannot be tightly attached to the plug electrode, the two ends of the series conductive connecting copper pieces can still be connected to the plug electrode through the outer wall of the slot, preventing short circuits or open circuits.

[0029] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 2 As shown, the conventional copper sheet 101 is simply bent at both ends to form U-shaped connectors 102. These U-shaped connectors 102 cannot engage with the limiting block 112 in the slot 111 on the socket 11. Over time, the deformation causes the U-shaped connectors 102 to lose their elasticity and cannot provide sufficient elastic force to abut against the slot 111, thus causing them to loosen and potentially displace from the slot 111.

[0033] like Figure 1 As shown, this utility model embodiment provides a series conductive copper sheet structure. Both ends of the series conductive copper sheet are U-shaped connectors 1 formed by bending. The U-shaped connector 1 has a first copper sheet edge 2 on each of its two opposite top sides. The two first copper sheet edges 2 are bent toward the inside of the U-shaped connector 1 to form an arc surface structure.

[0034] The U-shaped connector 1 has at least one slot 3 on each of its opposite sides. When the plug is inserted, the minimum distance between the two first copper pieces along the edge 2 is equal to the minimum distance between the two opposite slots 3.

[0035] In this embodiment, by setting the slot 3 to engage with the limiting block 112 in the slot 111 of the socket 11, the U-shaped connector 1 is securely installed in the slot 111 of the socket 11, preventing displacement. In addition, the minimum distance between the two opposing slots 3 is exactly equal to the minimum distance along the edge 2 of the two first copper pieces when the plug is inserted. This minimum distance is also the thickness of the plug electrode piece 12. When the two first copper pieces cannot be tightly attached to the plug electrode piece 12 along the edge 2, the two ends of the series conductive connecting copper pieces can still be connected to the plug electrode piece 12 through the outer wall of the slot 3, avoiding short circuits or open circuits.

[0036] like Figure 3-5 As shown, specifically, the series conductive copper sheet structure includes a copper sheet body 100, and the U-shaped connector 1 includes a first sheet 1001, a second sheet 1002, and a third sheet 1003 connected in sequence; for one of the U-shaped connectors 1, the first sheet 1001 is one end of the copper sheet body 100, the angle between the second sheet 1002 and the first sheet 1001 is 90°, and the angle between the third sheet 1003 and the second sheet 1002 is 90°; an electrode mounting position 3001 is provided between the first sheet 1001 and the third sheet 1003.

[0037] The first copper sheet edge 2 is disposed on the first sheet body 1001 and the third sheet body 1003; the first copper sheet edge 2 includes a first copper edge portion 2001, a second copper edge portion 2002 and a third copper edge portion 2003 that are sequentially adjacent to each other.

[0038] The copper edge portion 2001, the second copper edge portion 2002, and the third copper edge portion 2003; the second copper edge portion 2002 is disposed closer to the electrode plate mounting position 3001 than the first copper edge portion 2001, and the second copper edge portion 2002 is higher than the first copper edge portion 2001; the third copper edge portion 2003 is disposed further away from the electrode plate mounting position 3001 than the second copper edge portion 2002, and the third copper edge portion 2003 is higher than the second copper edge portion 2002;

[0039] The second copper sheet edge 5 described below is disposed on the second sheet body 1002, and the second copper sheet edge 5 has the same structure as the first copper sheet edge 2.

[0040] In this embodiment, the opening of the slot 3 extends to the upper surface of the first copper sheet edge 2, and the top of the slot 3 coincides with the second copper edge 2002 of the first copper sheet edge 2.

[0041] The opening of the slot 3 connects with the upper surface of the first copper sheet edge 2, which enhances the structural strength of the first copper sheet edge 2 and prevents excessive deformation of the first copper sheet edge 2. The top of the slot 3 coincides with the second copper edge 2002 of the first copper sheet edge 2. Its function is that when the plug electrode 12 is inserted, the plug electrode 12 is connected not only to the first copper sheet edge 2 but also to the outer wall of the slot 3. This ensures that even if the first copper sheet edge 2 is excessively deformed and cannot be restored, the plug electrode 12 can still connect with the U-shaped connector 1 through the outer wall of the slot 3, thereby avoiding poor contact due to excessive deformation of the first copper sheet edge 2.

[0042] Furthermore, a copper plate 4 is provided on the bottom outer wall of the slot 3 to increase the contact area with the plug electrode plate.

[0043] In this embodiment, the copper plate 4 can be relatively thin. Its main function is to increase the contact area with the plug electrode piece, reduce the probability of poor contact, and also to squeeze the plug electrode piece 12, so that the plug electrode piece 12 is more firmly inserted into the U-shaped connector 1 and will not fall off at will.

[0044] Furthermore, the first copper sheet is integrally formed with the slot 3 along its edge 2.

[0045] In this embodiment, the integrally formed structure has good structural strength, which avoids the U-shaped connector 1 from undergoing large deformation after being repeatedly inserted and removed by the plug electrode plate 12, which would cause the inner space of the U-shaped connector 1 to expand or form an irregular structure, resulting in poor contact and unstable insertion.

[0046] Furthermore, the slot 3 is an arc-shaped structure formed by folding the two ends of the series conductive copper sheet, and the first copper sheet is welded along the edge 2 to the top of the slot 3.

[0047] In this embodiment, another structural embodiment of the first copper sheet edge 2 and the slot 3 is provided. Its effect is that when the first copper sheet edge 2 cannot recover its elastic deformation after repeated insertion and removal, the plug electrode 12 can not only be connected to the outer wall of the slot 3, but also be manually disassembled, repaired and soldered.

[0048] Furthermore, the third side of the U-shaped connector 1 is provided with a second copper strip edge 5, and the second copper strip edge 5 is bent toward the inside of the U-shaped connector 1.

[0049] In this embodiment, the purpose of providing the second copper sheet edge 5 is to increase the contact area between the U-shaped connector 1 and the plug electrode sheet 12. At the same time, its arc-shaped bending structure can guide the plug electrode sheet 12 to be inserted into the inside of the U-shaped connector 1 during the insertion process.

[0050] Furthermore, a power connection piece 6 is provided in the middle of the copper sheet, and the power connection piece 6 is bent to one side and forms a 90° angle with the copper sheet.

[0051] In this embodiment, the power connector 6 is typically connected to an external power cord, usually a live wire and a neutral wire. Its 90° bend can help fix the middle of the series conductive copper connector, increasing the stability of the series conductive copper connector as a whole installed on the socket 11 and preventing displacement.

[0052] Furthermore, the power connection piece 6 has a through hole 601 for mounting bolts.

[0053] In this embodiment, the power connector 6 is fixed to the socket 11 by bolts passing through the through hole 601.

[0054] Furthermore, at least one auxiliary plate 602 is provided on the outer side of the power connection piece 6, and the auxiliary plate 602 is bent to one side and forms a 90° angle with the power connection piece 6.

[0055] In this embodiment, the auxiliary plate 602 is used to position the power connection piece 6 to prevent misalignment between the through hole 601 and the threaded hole on the socket 11 during installation.

[0056] Furthermore, a long groove 7 is formed in the middle of the copper sheet, and the bottom of the groove 7 protrudes from one side of the middle of the copper sheet.

[0057] In this embodiment, the long strip groove 7 mainly increases the overall structural strength of the series conductive copper sheet, which is equivalent to a reinforcing rib. Furthermore, the fact that it protrudes from one side of the middle of the copper sheet may allow it to fit better with the internal structure of the socket 11.

[0058] Furthermore, the two ends of the groove 7 are close to the two U-shaped connectors 1, and the shape of the groove 7 is rectangular or elliptical.

[0059] In this embodiment, the longer the overall length of the groove 7, the more effectively the overall structural strength of the series conductive copper sheet can be increased. The shape of the groove 7 can be changed according to the shape of other components on the socket 11 so as to fit more snugly and securely on the socket 11.

[0060] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
