Description

Technical Field

[0001] This utility model relates to the technical field of wire connection, and more specifically to a connection structure and socket for a wire and a sheet conductor. Background Technology

[0002] Currently, the connection methods between the wires and internal copper strips in wired sockets include lap soldering, through-hole soldering, and resistance welding. However, all of these methods suffer from problems such as incomplete soldering and weak welds. Lap soldering involves directly soldering the wire end onto the copper strip without prior securing; in cases of incomplete soldering, the connection will break immediately. Through-hole soldering involves inserting the wire end into a hole in the copper strip before soldering; the wire can move within the hole before soldering, but in cases of incomplete soldering, the connection is prone to breakage. Resistance welding connects the wire end and the copper strip through electrode clamps at high temperatures, but current resistance welding technology has a high failure rate. The new national standard GB2099.7-2024 requires that when soldering the wire to the internal copper strip, the wire must be hooked and secured through a not-too-large hole before soldering. Many products in the industry currently do not meet the requirements of this new standard. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a connection structure between a wire and a sheet conductor. Before welding, the connection between the wire and the sheet conductor is stable, safe and reliable, meets the requirements of the new national standard, and is low in cost. It requires little modification to the existing technology, no new equipment investment, no pre-processing is required, it can be produced on the production line, and has high quality stability.

[0004] The technical solution of this utility model is to provide a connection structure between a wire and a sheet conductor, including a wire and a sheet conductor. The sheet conductor is provided with adjacent closed holes and half-through holes. The end of the wire first passes through the closed hole, and the part of the wire adjacent to the end is then inserted into the half-through hole. The end of the wire is locked by the closed hole and the half-through hole before being soldered to the sheet conductor.

[0005] Compared with the prior art, the connection structure of the wire and the sheet conductor of this utility model has the following advantages: the end of the wire first passes through the closed hole, and the part of the wire located behind the end is then inserted into the half-through hole. In this way, the end of the wire cannot move in the direction perpendicular to the sheet conductor or in the direction parallel to the sheet conductor. That is, the end of the wire is locked by the closed hole and the half-through hole and cannot break free. The connection between the wire and the sheet conductor before soldering is stable, safe and reliable, which meets the requirements of the new national standard. Moreover, since it requires little modification to the existing technology, no new equipment investment is needed, no pre-process is required, it can be produced on the production line, the cost is low, and the quality stability after soldering is high. Even if there is a cold solder joint, it will not break.

[0006] Preferably, the half-through hole includes an opening and a receiving area; the gap of the opening is not less than the diameter of the wire, used to guide the wire into the receiving area; the receiving area is the internal part of the half-through hole, used to accommodate the inserted wire. This structure is simple and facilitates the processing of the half-through hole.

[0007] Preferably, a locking part is provided between the opening and the receiving area. The gap of the locking part is no greater than the diameter of the wire, allowing the wire to be squeezed into the gap of the locking part and enter the receiving area. The locking part is used to lock the wire within the receiving area. This structure prevents the wire stuck in the half-through hole from coming out of the receiving area.

[0008] Preferably, the opening is funnel-shaped with the gap gradually increasing from the inside to the outside, and the locking part is located at the end of the opening facing the receiving area. This structure is simple and facilitates the machining of half-holes.

[0009] Preferably, the closed hole is circular or a regular polygon. This structure, with its uniform circular or regular polygonal shape in all four directions, combined with a wire having a circular cross-section, prevents the wire from moving in any direction within the closed hole.

[0010] Preferably, the receiving area is a circle or regular polygon with a notch. This structure ensures that the circle or regular polygon is uniform in all four directions, preventing the wire from moving in any direction within the receiving area.

Wires of the same polarity are electrically connected to the corresponding conductive copper strip. The electrical connection structure adopts the connection structure of wire and sheet conductor as described above.

[0012] Compared with the prior art, the socket of this utility model has the following advantages: the L-pole socket is electrically connected to the L-pole wire in the power cord through the same L-pole conductive copper strip; the N-pole socket is electrically connected to the N-pole wire in the power cord through the same N-pole conductive copper strip; if an E-pole socket is provided in the base, the E-pole socket is electrically connected to the E-pole wire in the power cord through the same E-pole conductive copper strip; the electrical connection structure between the wire and the conductive copper strip adopts the connection structure of the wire and the sheet conductor as described above, that is, the end of the wire is locked by the closed hole and half through hole of the conductive copper strip and cannot be freed, so that the connection between the wire and the conductive copper strip is stable, safe and reliable before soldering, which meets the requirements of the new national standard. The quality stability after soldering is high, and it will not break even if there is a cold solder joint.

[0013] Preferably, the sockets of the same polarity and the corresponding conductive copper strips are soldered together, or the sockets of the same polarity and the corresponding conductive copper strips are an integral structure. This structure does not limit the electrical connection method between the sockets of the same polarity and the corresponding conductive copper strips, allowing the connection structure of the wire and sheet conductor in this invention to be adapted to existing production lines. Because it requires minimal modification to existing technology, no new equipment investment is needed, no pre-processing is required, and it can be produced on the production line, resulting in low cost and rapid modification of existing product lines.

[0014] Preferably, a switch is provided inside the housing, with L-pole and N-pole switch pins. Conductive copper strips for the L-pole and N-pole are electrically connected to the corresponding switch pins, and wires for the L-pole and N-pole are also electrically connected to the corresponding switch pins. All electrical connections employ the wire-to-sheet conductor connection structure described above. This structure allows the wire-to-sheet conductor connection structure of this invention to be adapted to existing socket production lines with switch structures, requiring no additional equipment investment or pre-processing steps. It enables on-line production and rapid modification of existing product lines.

[0015] Preferably, the L, N, and E polarity conductors are all made of multiple strands of copper wire wound together, or are single-core wires composed of a single strand of copper wire. Using this structure, the connection structure between the conductor and the sheet conductor in this invention can adapt to existing conductor technologies, without limiting the shape of the conductor, thus allowing for on-line production and rapid modification of existing product lines.

[0022] To better understand this application, various aspects of this application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0024] It should also be understood that the terms "comprising," "having," "including," and "containing," when used in this specification, indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof. Furthermore, when expressions such as "...at least one" appear after a list of listed features, they modify the entire listed feature, not individual elements in the list.

[0025] Example 1: like Figure 1 As shown, the connection structure between the wire and the sheet conductor of this utility model includes a wire 1 and a sheet conductor 2. The sheet conductor 2 is provided with adjacent closed holes 2-1 and half-through holes 2-2. The closed holes 2-1 are circular, and the receiving area 2-5 is a circular shape with a notch. The end of the wire 1 first passes through the closed hole 2-1, and the portion of the wire 1 adjacent to the end is then inserted into the half-through hole 2-2. The end of the wire 1 is locked by the closed hole 2-1 and the half-through hole 2-2 before being soldered to the sheet conductor 2. In this embodiment, the sheet conductor 2 is made of conductive copper strip 3. In other embodiments, other metal materials or conductor materials can also be used to form the sheet structure.

[0026] The half-through hole 2-2 includes an opening 2-3, a locking part 2-4, and a receiving area 2-5. The gap of the opening 2-3 is not less than the diameter of the wire 1, and the opening 2-3 is a funnel shape with the gap gradually increasing from the inside to the outside, used to guide the wire 1 into the receiving area 2-5. The receiving area 2-5 is the internal position of the half-through hole 2-2, used to accommodate the inserted wire 1. The locking part 2-4 is located between the opening 2-3 and the receiving area 2-5. The gap of the locking part 2-4 is not greater than the diameter of the wire 1, allowing the wire 1 to squeeze into the gap of the locking part 2-4 and enter the receiving area 2-5. The locking part 2-4 is used to lock the wire 1 within the receiving area 2-5. In this embodiment, the locking part 2-4 is located at the end of the opening 2-3 facing the receiving area 2-5.

[0027] The end of the wire 1 first passes through the closed hole 2-1, and then the part of the wire 1 located behind the end is inserted into the half-through hole 2-2. In this way, the end of the wire 1 cannot move in the direction perpendicular to the sheet conductor 2 or in the direction parallel to the sheet conductor 2. That is, the end of the wire 1 is locked by the closed hole 2-1 and the half-through hole 2-2 and cannot break free. This makes the connection between the wire and the sheet conductor stable, safe and reliable before soldering, which meets the requirements of the new national standard. Moreover, since it requires little modification to the existing technology, no new equipment investment is needed, no previous process is required, it can be produced on the production line, the cost is low, the quality stability after soldering is high, and even if there is a cold solder joint, it will not break.

[0028] Example 2: like Figure 2 As shown, the difference between the connection structure of the wire and the sheet conductor of this utility model and that of Embodiment 1 is that in this embodiment, the closed hole 2-1 is square, and the receiving area 2-5 is square with a notch. The square shape is uniform in all four directions, and when combined with the wire 1 with a circular cross-section, it can prevent the wire 1 from moving in any direction within the closed hole 2-1. The effect of limiting the wire 1 is no worse than that of the circle.

[0029] Example 3: like Figure 3 As shown, the socket of this utility model includes an insulating shell composed of a lower cover and an upper cover 8 that are connected to each other. A power cord 6 is provided on the shell. The power cord 6 includes wires with three polarities: L, N, and E. At least one base 7 is provided inside the shell. The base 7 is provided with sockets with three polarities: L, N, and E. Three conductive copper strips 3 with L, N, and E polarities are provided inside the shell. The sockets and conductive copper strips 3 are independent of each other. The sockets with the same polarity are soldered to the corresponding conductive copper strips 3. The wires with the same polarity and the corresponding conductive copper strips 3 adopt the connection structure of wires and sheet conductors as described in Embodiment 1.

[0030] In this embodiment, the L-pole sleeve is electrically connected to the L-pole wire in the power line 6 through the same L-pole conductive copper strip 3; the N-pole sleeve is electrically connected to the N-pole wire in the power line 6 through the same N-pole conductive copper strip 3; if an E-pole sleeve is provided in the base 7, the E-pole sleeve is electrically connected to the E-pole wire in the power line 6 through the same E-pole conductive copper strip 3; in the electrical connection structure between the wire and the conductive copper strip 3, the end of the wire is locked by the closed hole 2-1 and the half-through hole 2-2 of the conductive copper strip and cannot be freed, so that the connection between the wire and the conductive copper strip is stable, safe and reliable before soldering, which meets the requirements of the new national standard. The quality stability after soldering is high, and it will not break even if there is a cold solder joint.

[0031] Example 4: like Figure 4 As shown, the difference between the socket of this utility model and Embodiment 3 is that in this embodiment, the socket with the same polarity and the corresponding conductive copper strip 3 are integrated into the socket copper strip 4, that is, the socket with the L pole and the conductive copper strip 3 with the L pole are integrated into the socket, the socket with the N pole and the conductive copper strip 3 with the N pole are integrated into the socket, and the socket with the E pole and the conductive copper strip 3 with the E pole are integrated into the socket. However, the wires with the same polarity and the corresponding conductive copper strip 3 still adopt the connection structure of wire and sheet conductor as described in Embodiment 1.

[0032] The connection structure between the wire and the sheet conductor in this invention can be adapted to existing production lines. Regardless of whether the socket and the corresponding conductive copper strip 3 of the same polarity are separate structures connected by soldering or integrated structures manufactured by bending, the connection structure between the wire and the sheet conductor in this invention can be adapted. Because the connection structure between the wire and the sheet conductor in this invention requires little modification to existing technology, no new equipment investment is needed, no previous processes are required, and it can be produced on the production line. Therefore, the cost is low and existing product lines can be quickly modified.

[0033] Example 5: like Figure 5 As shown, the difference between the socket of this utility model and Embodiment 3 is that, in this embodiment, a switch 5 is provided inside the housing, and the switch 5 is provided with switch pins 5-1 of L pole and N pole. The conductive copper strips 3 of L pole and N pole are electrically connected to the switch pins 5-1 of L pole and N pole respectively. The wires of L pole and N pole are respectively connected to the switch pins 5-1 of L pole and N pole respectively and adopt the connection structure of wire and sheet conductor as described in Embodiment 1. The socket of E pole is still electrically connected to the wire of E pole in power line 6 through the conductive copper strip 3 of E pole as in Embodiment 3.

[0034] For existing socket production lines with switch structures, the connection structure between the wire and the sheet conductor in this invention can also be adapted without additional equipment investment or pre-processing. It can be produced on the production line. Moreover, in this embodiment, the wires of the three polarities, L, N, and E, can all be made of multiple strands of copper wire coiled together, or they can be single-core wires made of a single strand of copper wire. Neither of these affects the modification of the existing technology by the connection structure between the wire and the sheet conductor in this invention. The method of this invention can quickly complete the modification of the existing product line.

[0035] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
