Description

Technical Field

[0001] This application relates to socket technology, and particularly to a conductive connection member and a multi-port socket. Background Art

[0002] For the connection members of a multi-port socket, such as the N-pole copper bar and the L-pole copper bar, each has a plurality of socket connection points for connecting sockets to form multiple holes. The fusing and burning of the N-pole copper bar and the L-pole copper bar are an important reason for the damage of the multi-port socket. It can be seen that it is necessary to improve the connection member to reduce the probability of burning.

[0003] Currently, by increasing the width or thickness of the connection member as a whole, the resistance of the entire connection member is reduced to reduce the probability of its being fused and burned.

[0004] The inventor found that the prior art has at least the following technical problems:

[0005] Increasing the width or thickness of the connection member as a whole will cause material waste. Summary of the Invention

[0006] In view of this, the embodiments of this application provide a conductive connection member and a multi-port socket, which can not only reduce the probability of the connection member being burned, but also avoid material waste.

[0007] Specifically, the following technical solutions are included:

[0008] On the one hand, the embodiments of this application provide a conductive connection member for a multi-port socket. The conductive connection member includes a plurality of connection segments, and the plurality of connection segments are connected in sequence and correspond one by one to a corresponding number of sockets.

[0009] Among the plurality of connection segments, the resistance of the first connection segment is the smallest, and the first connection segment is the connection segment adjacent to the wiring terminal of the socket.

[0010] In a possible design, the conductivity of the plurality of connection segments is the same, and each connection segment has a standard length. Among the plurality of connection segments, the cross-sectional area of the first connection segment is the largest.

[0011] In a possible design, along the direction away from the wiring terminal, the cross-sectional areas of the plurality of connection segments decrease in sequence.

[0012] In a possible design, the ratio of the cross-sectional areas of the connection segments is proportional to the ratio of the probabilities of the current flowing through each connection segment.

[0013] In a possible design, the cross-sectional shapes of the plurality of connection segments are all rectangular, and the cross-sectional lengths of the plurality of connection segments are the same;

[0014] The value range of the cross-sectional width W1 of the first connection segment is: 0.5 mm < W1 < 0.65 mm.

[0015] In a possible design, the cross-sectional shapes of the plurality of connection segments are all rectangular, and the cross-sectional widths of the plurality of connection segments are the same;

[0016] The value range of the cross-sectional length L1 of the first connection segment is: 3.6 mm < L1 < 4.5 mm.

[0017] In a possible design, the cross-sectional shapes of the plurality of connection segments are all rectangular, and the cross-sectional lengths and cross-sectional widths of the plurality of connection segments are all different;

[0018] The value range of the cross-sectional area S1 of the first connection segment is: 1.8 mm 2 < S1 < 2.5 mm 2 .

[0019] In a possible design, the cross-sectional shapes of the plurality of connection segments are all circular;

[0020] The value range of the radius R1 of the first connection segment is: 0.757 mm < R1 < 0.892 mm.

[0021] In a possible design, each of the connection segments has standard geometric dimensions, and the conductivity of the first connection segment is the largest.

[0022] In a possible design, along the direction away from the terminal, the conductivity of the plurality of connection segments decreases in sequence.

[0023] In a possible design, the conductive connector is a copper bar or a multi-core wire.

[0024] In a possible design, the connector includes at least one of an N-pole connector and an L-pole connector.

[0025] In another aspect, an embodiment of the present application provides a multi-hole socket, and the multi-hole socket includes any one of the above conductive connectors.

[0026] The beneficial effects of the technical solution provided by the embodiment of the present application at least include:

[0027] The conductive connector provided by the embodiment of the present application has the highest probability of conducting and interrupting current in the first connection section adjacent to the wiring terminal of the socket, and also has the highest probability of fusing. By minimizing the resistance of the first connection section, the probability of its burning and fusing is reduced, which is beneficial to improving the overall service life of the conductive connector. Since only the first connection section that affects the ultimate life of the conductive connector can be improved, for example, by increasing its cross-sectional area to minimize its resistance, material waste can be avoided and the cost can be reduced.

[0055] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0056] The conductive connector conducts current as a conductor inside the socket. The following describes the layout of the conductive connector in the socket in conjunction with the attached Figure 1 drawings:

[0057] As shown in the appendix Figure 1 As shown, the three - level socket includes: a housing 2; a socket base 3 and a terminal on the housing 2; and a conductive connecting member on the socket base 3. Among them, the terminal includes an N (neutral) - pole terminal 4 - 1, an L (live) - pole terminal 4 - 2, and an E (ground) - pole terminal 4 - 3; correspondingly, the conductive connecting member includes an N - pole conductive connecting member 1 - 1, an L - pole conductive connecting member 1 - 2, and an E - pole conductive connecting member 1 - 3.

[0058] Taking the N - pole conductive connecting member 1 - 1 as an example, one end of the N - pole conductive connecting member 1 - 1 is connected to the N - pole terminal 4 - 1, and one N - pole socket 5 - 1 is respectively connected to the position of the N - pole conductive connecting member 1 - 1 corresponding to each hole position of the socket.

[0059] In the embodiment of the present application, as shown in the appendix Figure 2 and the appendix Figure 3 As shown, both the N - pole conductive connecting member 1 - 1 and the L - pole conductive connecting member 1 - 2 have a plurality of socket connection points 101. Taking the socket connection points 101 as the boundary, the conductive connecting member is divided into a plurality of sequentially connected connection segments 102 (that is to say, each connection segment 102 corresponds to a hole position of a multi - hole socket).

[0060] The N - pole conductive connecting member 1 - 1 and the L - pole conductive connecting member 1 - 2 use the socket connection points 101 thereon to connect the sockets. Among them, the number of sockets, the number of hole positions of the socket, and the number of connection segments correspond to each other one by one to form the hole positions on the socket.

[0061] For the sake of convenience of description, in the embodiment of the present application, the "connection segment adjacent to the terminal of the socket" in the conductive connecting member is called the first connection segment 1021 (which is closest to the terminal of the socket). Along the direction away from the terminal, the remaining connection segments can be called the second connection segment 1022,... the nth connection segment in sequence, where n≥3.

[0062] The appendix Figure 4 illustrates the distribution of each connection segment of the N - pole conductive connecting member 1 - 1 and the L - pole conductive connecting member 1 - 2 in a three - hole socket. As shown in the appendix Figure 4 As shown, the connection segments of the N - pole conductive connecting member 1 - 1 and the L - pole conductive connecting member 1 - 2 adjacent to the N - pole terminal 4 - 1 and the L - pole terminal 4 - 2 of the socket are both called the first connection segment 1021. Along the direction away from the N - pole terminal 4 - 1 and the L - pole terminal 4 - 2, the remaining connection segments of the two are called the second connection segment 1022 and the third connection segment 1023 in sequence.

[0063] The inventors' research found that for a multi-hole socket damaged due to the burnout and melting of the conductive connection components, most (e.g., more than 90%) of the melting positions of the conductive connection components are close to the terminal blocks.

[0064] Taking Figure 1 the three-pole socket with three holes shown as an example, there are 3 N-pole socket sleeves 5-1 and 3 L-pole socket sleeves 5-2 respectively connected to the N-pole conductive connection component 1-1 and the L-pole conductive connection component 1-2. Taking the socket joint of the conductive connection component and the socket sleeve as the boundary, both the N-pole conductive connection component 1-1 and the L-pole conductive connection component 1-2 are divided into 3 connection segments. Along the direction away from the N-pole terminal block 4-1 and the L-pole terminal block 4-2 of the socket, these 3 connection segments are successively called the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 (the corresponding hole positions are the 1st hole position ①, the 2nd hole position ②, and the 3rd hole position ③). The inventors' research confirmed that the melting positions of the N-pole conductive connection component 1-1 and the L-pole conductive connection component 1-2 are concentrated in the first connection segment 1021.

[0065] The three-hole socket can supply power to up to 3 electrical appliances at one time. It is random for the user to use 1, 2, or 3 electrical appliances at one time, and it is also random which hole position of the socket the user uses each time. According to permutations and combinations, the user's usage of hole positions, the current flow through each connection segment, and the corresponding probabilities are shown in Table 1:

[0066] Table 1

[0067]

[0068] As can be seen from Table 1, when the hole positions used by the user are random and the number of hole positions used each time is also random, the probability that the current flows through the first connection segment of the L-pole conductive connection component and the N-pole conductive connection component is 1, the probability that the current flows through the second connection segment of the L-pole conductive connection component and the N-pole conductive connection component is 6 / 7, and the probability that the current flows through the third connection segment of the L-pole conductive connection component and the N-pole conductive connection component is 4 / 7.

[0069] It can be seen that when the user uses this three-hole socket, the probabilities that the current flows through the first connection segment, the second connection segment, and the third connection segment of the L-pole conductive connection component and the N-pole conductive connection component are different. This results in different melting lifetimes of the first connection segment, the second connection segment, and the third connection segment of the L-pole conductive connection component and the N-pole conductive connection component under the same other conditions. Since the probability that the current flows through the first connection segment of the L-pole conductive connection component and the N-pole conductive connection component is the largest, as the number of uses of this three-hole socket increases, the first connection segment of the L-pole conductive connection component and the N-pole conductive connection component will reach the limit lifetime first, that is, it will be burned out and melted first.

[0070] It can be seen that for a multi-hole socket, the probabilities of current flowing through the three connection segments of the L-pole conductive connector and the N-pole conductive connector are different. This will cause the first connection segment to turn on and off the current at the highest frequency, while for the other connection segments, as the distance from the connection terminal increases, the frequency of turning on and off the current relatively decreases. Therefore, relatively speaking, the first connection segment of the conductive connector has the highest probability of overheating and fusing due to current.

[0071] As Figure 2 and as Figure 3 shown, an embodiment of the present application provides a conductive connector for a multi-hole socket. The conductive connector includes a plurality of connection segments 102, where the plurality of connection segments 102 are connected in sequence and correspond to the same number of socket sleeves one by one.

[0072] Among the plurality of connection segments 102, the first connection segment 1021 has the smallest resistance, where the first connection segment 1021 is the connection segment 102 adjacent to the connection terminal of the socket.

[0073] For the conductive connector provided by the embodiment of the present application, since the connection segment 102 (i.e., the first connection segment 1021) adjacent to the connection terminal of the socket has the highest probability of turning on and off the current and the highest probability of fusing, by making the resistance of the first connection segment 1021 the smallest, the probability of its burning and fusing is reduced, which is beneficial to improving the overall service life of the conductive connector. Since only the first connection segment 1021 that affects the ultimate life of the conductive connector can be improved, for example, by increasing its cross-sectional area to make its resistance the smallest, material waste can be avoided and the cost can be reduced.

[0074] In the embodiment of the present application, the conductive connector includes a plurality of connection segments 102, which can be understood as including two or more connection segments 102. For example, it can include two connection segments 102, three connection segments 102 (see As Figure 2 and as Figure 3 ), four connection segments 102, five connection segments 102, six connection segments 102, etc.

[0075] A bending structure 103 is generally formed at the end of the conductive connector adjacent to the connection terminal of the socket, and the bending structure 103 is used to connect with the connection terminal of the socket. Therefore, the "direction away from the connection terminal" involved in the embodiment of the present application can also be understood as the direction away from the bending structure 103 of the conductive connector.

[0076] In the embodiment of the present application, among the plurality of connection segments 102, the resistance of the first connection segment 1021 is made the smallest. For the remaining connection segments 102, they can be not improved, or some or all of them can be improved to make their resistances greater than that of the first connection segment 1021 respectively.

[0077] As an example, the resistance of the first connection segment 1021 can be minimized, and at the same time, the resistances of the second connection segment 1022, ..., the nth connection segment are the same and greater than the resistance of the first connection segment 1021 (where n≥3).

[0078] As another example, the resistance of the first connection segment 1021 can be minimized, and at the same time, the resistances of the second connection segment 1022, ..., the nth connection segment are partially the same (where n≥3).

[0079] For example, when n = 5, in the direction away from the terminal, the conductive connection member includes a first connection segment, a second connection segment, a third connection segment, a fourth connection segment, and a fifth connection segment connected in sequence. The resistance of the first connection segment is minimized, and the resistances of any two or three of the second connection segment, the third connection segment, the fourth connection segment, and the fifth connection segment are the same.

[0080] As still another example, the resistance of the first connection segment 1021 can be minimized, and at the same time, the resistances of the second connection segment 1022, ..., the nth connection segment are different from each other (where n≥3).

[0081] For example, when n = 5, in the direction away from the terminal, the conductive connection member includes a first connection segment, a second connection segment, a third connection segment, a fourth connection segment, and a fifth connection segment connected in sequence. The resistance of the first connection segment is minimized, and the resistances of the second connection segment, the third connection segment, the fourth connection segment, and the fifth connection segment increase in sequence.

[0082] In a possible design, for the conductive connection member provided in the embodiment of the present application, in the direction away from the terminal, the resistances of the plurality of connection segments 102 can increase in sequence, that is, the resistances of the first connection segment 1021, the second connection segment 1022, ..., the nth connection segment increase in sequence (where n≥3). In this way, on the premise of reducing the probability of the conductive connection member being melted and burned out, the cost can be minimized (for example, the cross-sectional areas of the plurality of connection segments are gradually reduced to save raw material costs).

[0083] The ratio of the resistances of each connection segment 102 can be made inversely proportional to the ratio of the probabilities of the current flowing through each connection segment 102. In this way, in the direction away from the terminal, since the probabilities of the current flowing through the respective connection segments 102 gradually decrease, and the resistances of the respective connection segments 102 can increase proportionally, the increase amplitude of the resistance of the current connection segment 102 compared to the previous connection segment 102 is determined by the probability of the current flowing through each connection segment 102 (for example, to determine the increase amplitude of the second connection segment 1022 compared to the first connection segment 1021), so that the ultimate life of each connection segment 102 of the conductive connection member reaches consistency, solving the problem of the life of the conductive connection member having a bucket effect and maximizing cost savings.

[0084] For example, when the conductive connection member includes m connection segments 102 (where m≥2), assume the resistance of the first connection segment 1021 is R1, and the probability that current flows through the first connection segment 1021 is a fixed value of 1. Assume the resistance of the m-th connection segment is R m , and the probability that current flows through the m-th connection segment is P m , then R m = (R1×1)÷P m .

[0085] The resistance can be changed to meet the design requirements by changing the cross-sectional area of the connection segment, or by changing the conductivity of the connection segment. The following elaborates on these two implementation methods respectively:

[0086] In a possible design, in the conductive connection member provided in the embodiment of the present application, the conductivities of the multiple connection segments 102 are the same, and each connection segment 102 has a standard length. Among the multiple connection segments 102, the cross-sectional area of the first connection segment 1021 is the largest.

[0087] In a state where the conductivity and length of the multiple connection segments 102 are fixed, by making the cross-sectional area of the first connection segment 1021 the largest, the purpose of minimizing its resistance is achieved.

[0088] It should be noted that the above-mentioned "each connection segment 102 has a standard length" means that, on the premise that the number of holes in the multi-hole socket is determined, the lengths of the N-pole connection member and the L-pole connection member included therein, as well as the lengths of the connection segments corresponding to each hole in the above-mentioned connection members, are all determined standard values. According to the general standards in the art, the length of each connection segment in the connection member can be determined, and the embodiment of the present application does not improve the length of the connection segment here.

[0089] Based on the above design, along the direction away from the terminal, the cross-sectional areas of the multiple connection segments 102 in the conductive connection member can gradually decrease, that is, the volumes of the connection segments 102 can be reduced to achieve the purpose of saving raw material costs.

[0090] Furthermore, the ratio of the cross-sectional areas of the connection segments 102 can be made proportional to the ratio of the probabilities that current flows through each connection segment 102. In this way, along the direction away from the terminal, since the probabilities that current flows through the connection segments 102 gradually decrease, the cross-sectional areas of the connection segments 102 gradually decrease according to the above ratio. The reduction amplitude of the cross-sectional area of the current connection segment compared to the previous connection segment is determined by the probability that current flows through each connection segment, and the cost is maximally reduced on the premise that the ultimate life of each connection segment 102 of the conductive connection member reaches consistency.

[0091] For example, when the conductive connection member includes m connection segments 102 (where m ≥ 2), the cross-sectional area of the first connection segment 1021 is set as S1, and the probability that the current flows through the first connection segment 1021 is a fixed value of 1. The resistance of the m-th connection segment is set as S m , and the probability that the current flows through the m-th connection segment is P m , then S m = S1 × P m .

[0092] By changing the cross-sectional dimensions of the connection segments to change the cross-sectional areas of the respective connection segments, so that the cross-sectional dimensions of the first connection segment are the largest. Among them, based on the cross-sectional shape of the connection segment, the cross-sectional dimensions include at least one of length, width, and radius.

[0093] For example, when the cross-sectional shape of the conductive connection member is rectangular (for example, a copper bar), the cross-sectional dimensions to be changed can be the cross-sectional width and / or width. For example, when the cross-sectional shape of the conductive connection member is circular, the cross-sectional dimension to be changed can be the radius.

[0094] Taking the conductive connection member with a rectangular cross-sectional shape as an example (the conductive connection member of this structure can be called a connection bar), it includes m connection segments 102 with the same conductivity (where m ≥ 2), and each connection segment 102 has a standard length.

[0095] The cross-sectional area of the first connection segment 1021 of the conductive connection member can be increased compared with the prior art, and it is the largest among all the connection segments 102. Further, the cross-sectional areas of the remaining connection segments 102 can be sequentially reduced along the direction away from the terminal, and the reduction amplitude of the cross-sectional area of each connection segment 102 is determined by the probability that the current flows through this connection segment.

[0096] In a possible design, the cross-sectional shapes of the multiple connection segments 102 of the conductive connection member provided in the embodiment of the present application are all rectangular, and the cross-sectional lengths of the multiple connection segments 102 are the same. The cross-sectional width W1 of the first connection segment 1021 can be made the largest, and the value range of W1 is: 0.5 mm < W1 < 0.65 mm. When the cross-sectional width W1 of the first connection segment 1021 is within the above range, not only can the resistance be reduced and the ultimate life of the conductive connection member be improved, but also the design requirements of the multi-hole socket are met.

[0097] Exemplarily, the cross-sectional width W1 of the first connection segment 1021 can be 0.51 mm, 0.52 mm, 0.53 mm, 0.54 mm, 0.55 mm, 0.56 mm, 0.57 mm, 0.58 mm, 0.59 mm, 0.60 mm, 0.61 mm, 0.62 mm, 0.63 mm, 0.64 mm, etc.

[0098] It should be noted that in the embodiments of the present application, as shown in the attached Figure 5 figures, the cross-sectional length L of the connection segment refers to the length of the side with a relatively longer cross-sectional length (which can also be understood as the width of the connection segment), and the cross-sectional width W refers to the length of the side with a relatively shorter cross-sectional length (which can also be understood as the thickness of the connection segment).

[0099] Further, as shown in the attached Figure 6 figures and Figure 7 the attached figures, along the direction away from the terminal, the cross-sectional width of the remaining connection segments 102 can be gradually reduced.

[0100] When the cross-sectional lengths of the connection segments 102 are the same, set the cross-sectional width W1 of the first connection segment 1021. According to the probability of current flowing through each connection segment 102, the cross-sectional width W of the remaining connection segments can be determined using the following formula m :

[0101] W m = the probability P of current flowing through the current connection segment m ×W1.

[0102] In another possible design, the cross-sectional shapes of the multiple connection segments 102 of the conductive connector provided in the embodiments of the present application are all rectangular, and the cross-sectional widths of the multiple connection segments 102 are the same. The cross-sectional length L1 of the first connection segment 1021 can be made the largest, and the value range of the cross-sectional length L1 is: 3.6 mm < L1 < 4.5 mm. When the cross-sectional length L1 of the first connection segment 1021 is within the above range, not only can the resistance be reduced and the ultimate life of the conductive connector be improved, but also the design requirements of the multi-hole socket are met.

[0103] Exemplarily, the cross-sectional length L1 of the first connection segment 1021 can be 3.72 mm, 3.75 mm, 3.78 mm, 3.8 mm, 3.85 mm, 3.9 mm, 3.95 mm, 4 mm, 4.05 mm, 4.1 mm, 4.15 mm, 4.2 mm, 4.25 mm, 4.3 mm, 4.35 mm, 4.4 mm, etc.

[0104] Further, as shown in the attached Figure 8 figures and Figure 9 the attached figures, along the direction away from the terminal, the cross-sectional lengths of the remaining multiple connection segments 102 can be gradually reduced.

[0105] When the cross-sectional widths of the connection segments 102 are the same, set the cross-sectional length of the first connection segment 1021 as L1. According to the probability of current flowing through each connection segment 102, the cross-sectional length L of the remaining connection segments can be determined using the following formulam :

[0106] L m = Probability P that current flows through the current connection segment m × L1.

[0107] In a possible design, along the direction away from the terminal, both the width and the cross-sectional width of the conductive connector provided by the embodiment of the present application are different, that is, they decrease in sequence.

[0108] In another possible design, the cross-sectional shapes of the multiple connection segments 102 of the conductive connector provided by the embodiment of the present application are all rectangular, and the cross-sectional width and length of the multiple connection segments 102 are the same, which can make the cross-sectional area S1 of the first connection segment 1021 the largest, and the value range of the cross-sectional area S1 is: 1.8 mm 2 <S1<2.5 mm 2 . When the cross-sectional area S1 of the first connection segment 1021 is within the above range, it can not only reduce the resistance and improve the ultimate life of the conductive connector, but also meet the design requirements of the multi-hole socket.

[0109] Exemplarily, the cross-sectional area S1 of the first connection segment 1021 can be 1.9 mm 2 , 1.95 mm 2 , 2.0 mm 2 , 2.1 mm 2 , 2.2 mm 2 , 2.3 mm 2 , 2.35 mm 2 , 2.4 mm 2 and so on.

[0110] Further, along the direction away from the terminal, the cross-sectional areas of the remaining multiple connection segments 102 can be made to decrease in sequence.

[0111] Set the cross-sectional area of the first connection segment 1021 as S1. According to the probability that current flows through each connection segment 102, the following formula can be used to determine the cross-sectional area S of the remaining connection segments m :

[0112] S m = Probability P that current flows through the current connection segment m × S1.

[0113] When the cross-sectional area S1 of the first connection segment 1021 is determined, if either the cross-sectional length or the cross-sectional width is set as a fixed value, the other can be calculated accordingly.

[0114] In yet another possible design, the cross-sectional shapes of the multiple connecting segments 102 of the conductive connector provided in the embodiments of the present application are all circular, and the value range of the radius R1 of the first connecting segment 1021 is: 0.757 mm < R1 < 0.892 mm, that is, the value range of the cross-sectional area S1 of the first connecting segment 1021 is: 1.8 mm 2 <S1<2.5 mm 2 .

[0115] When the radius R1 of the first connecting segment 1021 is within the above range, not only can the resistance be reduced and the ultimate life of the conductive connector be improved, but also the design requirements of the multi-hole socket are met.

[0116] Exemplarily, the radius R1 of the first connecting segment can be 0.76 mm, 0.77 mm, 0.78 mm, 0.79 mm, 0.8 mm, 0.81 mm, 0.82 mm, 0.83 mm, 0.84 mm, 0.85 mm, 0.86 mm, 0.87 mm, 0.88 mm, 0.89 mm, etc.

[0117] Further, in the direction away from the terminal, the radii of the remaining multiple connecting segments 102 can be sequentially reduced.

[0118] By setting the radius R1 of the first connecting segment 1021, according to the probability of the current flowing through each connecting segment 102, the radius of each of the remaining connecting segments can be determined as R using the following formula m :

[0119] R m = (P m ) 1 / 2 × R1.

[0120] It can be understood that for a conductive connector with a circular cross-section, the conductive connector of this structure can include a single conductor or multiple wires. When including multiple wires, the radius of the above connecting segment refers to the sum of the radii of multiple circular cross-section wires.

[0121] The following combines the above various possible designs to respectively provide an exemplary conductive connector for a three-hole socket, to illustrate the advantages of the structure and cost of the conductive connector provided in the embodiments of the present application compared to the conductive connectors provided in the prior art:

[0122] As shown in the attached Figure 10 and attached Figure 11 figures, the three-hole socket includes: an N-pole conductive connector 1-1, an L-pole conductive connector 1-2, and an optional ground-pole conductive connector 1-3. In the direction away from the terminal of the socket, it includes: a No. 1 hole position, a No. 2 hole position, and a No. 3 hole position, as shown in the attached Figure 2 and attached Figure 3As shown in the figure, the corresponding connection segments 102 on the conductive connection members are the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 respectively. Among them, the probability that the current flows through the first connection segment 1021 of the N-pole conductive connection member 1-1 and the L-pole conductive connection member 1-2 is 1, the probability that the current flows through the second connection segment 1022 of the N-pole conductive connection member 1-1 and the L-pole conductive connection member 1-2 is 6 / 7, and the probability that the current flows through the third connection segment 1023 of the N-pole conductive connection member 1-1 and the L-pole conductive connection member 1-2 is 4 / 7.

[0123] (1) As an example 1, as shown in the appended Figure 6 and the appended Figure 7 figure, the embodiments of the present application provide a conductive connection member with a rectangular cross-sectional area of the connection segment. Along the direction away from the terminal, the cross-sectional lengths of the three connection segments 102 included therein are the same, and the cross-sectional widths decrease in sequence.

[0124] On the one hand, since the cost of the conductive connection member provided by the embodiments of the present application must be less than the cost of the conductive connection member provided by the prior art, this makes the volume of the conductive connection member provided by the embodiments of the present application smaller than the volume of the conductive connection member provided by the prior art; on the other hand, the ultimate life of the conductive connection member provided by the embodiments of the present application must be greater than the ultimate life of the conductive connection member provided by the prior art, this makes the cross-sectional width of the first connection segment in the conductive connection member provided by the embodiments of the present application greater than the cross-sectional width of the conductive connection member provided by the prior art (the overall cross-sectional width of the conductive connection member provided by the prior art is consistent).

[0125] Based on the above two aspects, the value range of the cross-sectional width W1 of the first connection segment in the conductive connection member provided by the embodiments of the present application can be obtained, and any value within this value range can be used as the cross-sectional width of the first connection segment. After the cross-sectional width of the first connection segment is determined, according to the probability that the current flows through each connection segment, the cross-sectional widths W m of the remaining connection segments are also determined accordingly.

[0126] As shown in the appended Figure 6 figure, for the N-pole conductive connection member 1-1 provided by the embodiments of the present application, the cross-sectional lengths of each connection segment are all 3.6 mm, and the lengths of the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 are 55 mm, 42 mm, and 43 mm respectively (the lengths of the above three connection segments belong to a standard size of the N-pole conductive connection member, that is, for the N-pole conductive connection member 1-1, the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 have standard lengths of 55 mm, 42 mm, and 43 mm respectively).

[0127] Taking the N - pole conductive connector provided by the prior art as a comparison, it is set that the cross - sectional length of each connection segment is 3.6 mm, the cross - sectional width is 0.5 mm, and the lengths of the first connection segment, the second connection segment, and the third connection segment are 55 mm, 42 mm, and 43 mm respectively (the total length is 140 mm).

[0128] As shown in the attached Figure 7 figure, for the L - pole conductive connector 1 - 2 provided by the embodiment of the present application, it is set that the cross - sectional length of each connection segment 102 is 3.6 mm, and the lengths of the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 are 44 mm, 42 mm, and 42 mm respectively (the lengths of the above three connection segments belong to a standard size of the L - pole conductive connector, that is, for the L - pole conductive connector 1 - 2, the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 have standard lengths of 44 mm, 42 mm, and 42 mm respectively).

[0129] Taking the L - pole conductive connector provided by the prior art as a comparison, it is set that the cross - sectional length of each connection segment is 3.6 mm, the cross - sectional width is 0.5 mm, and the lengths of the first connection segment, the second connection segment, and the third connection segment are 44 mm, 42 mm, and 42 mm respectively (the total length is 128 mm).

[0130] (1.1) For the cross - sectional width W1 of the first connection segment 1021 of the L - pole conductive connector 1 - 2 provided by the embodiment of the present application, it is calculated in the following way:

[0131] First, the volume of the L - pole conductive connector provided by the embodiment of the present application < the volume of the L - pole conductive connector provided by the prior art, which makes (3.6×W1×44)+(3.6×6 / 7×W1×42)+(3.6×4 / 7×W1×42) < (3.6×0.5×128), and it is determined that W1 < 0.615 mm.

[0132] Second, the cross - sectional width of the first connection segment of the L - pole conductive connector provided by the embodiment of the present application > the cross - sectional width of the first connection segment of the L - pole conductive connector provided by the prior art, which makes W1 > 0.5 mm.

[0133] In summary, the value range of the cross - sectional width W1 of the first connection segment 1021 of the L - pole conductive connector 1 - 2 provided by the embodiment of the present application is: 0.5 mm < W1 < 0.615 mm. Any value within this range can be used as the cross - sectional width W1 of the first connection segment 1021 of the L - pole conductive connector 1 - 2. For example, 0.55 mm, 0.58 mm, 0.60 mm, 0.61 mm, etc.

[0134] According to the probability of current flowing through each connection segment, determine the cross-sectional width W2 of the second connection segment 1022 and the cross-sectional width W3 of the third connection segment 1023 of the L-pole conductive connector 1-2. Their calculation formulas are as follows:

[0135] In the embodiment of the present application, the cross-sectional width W2 of the second connection segment 1022 of the L-pole conductive connector 1-2 is W2 = 6 / 7×W1, and the cross-sectional width W3 of the third connection segment 1023 is W3 = 4 / 7×W1.

[0136] As an example, assume that the cross-sectional width W1 of the first connection segment 1021 of the L-pole conductive connector 1-2 provided in the embodiment of the present application is 0.6 mm. Then the cross-sectional width W2 of the second connection segment 1022 is 0.514 mm, and the cross-sectional width W3 of the third connection segment 1023 is 0.343 mm.

[0137] Based on the above data, calculate the cost reduction of the L-pole conductive connector of the three-hole socket compared with the prior art as follows:

[0138] (1) The volume V of the L-pole conductive connector provided in the present application is V = (44 mm×3.6 mm×0.6 mm) + (42 mm×3.6 mm×0.514 mm) + (42 mm×3.6 mm×0.343 mm) = 224.6 mm³.

[0139] (2) The volume V of the L-pole conductive connector provided by the prior art is V = 128 mm×3.6 mm×0.5 mm = 230.4 mm³.

[0140] It can be seen that the volume of the L-pole conductive connector provided in the embodiment of the present application is reduced by 5.8 mm³ compared with the prior art.

[0141] Taking the density of the L-pole conductive connector as 8.5 g / cm³ and the unit price as 41.14 yuan as an example, the reduction amount △M of the weight of the L-pole conductive connector provided in the embodiment of the present application compared with the prior art is △M = 8.5 g / cm³×5.8 mm³ = 0.05 g. Then the reduction amount △P of its cost compared with the prior art is △P = 0.05 g×41.14 yuan / kg = 0.0021 yuan.

[0142] (1.2) For the N-pole conductive connector 1-1 provided in the embodiment of the present application, according to the same method as above, it can be calculated that the value range of the cross-sectional width W1 of the first connection segment 1021 of the N-pole conductive connector 1-1 provided in the embodiment of the present application is: 0.5 mm < W1 < 0.606 mm. Any value within this range can be used as the cross-sectional width W1 of the first connection segment 1021 of the N-pole conductive connector 1-1. For example, 0.52 mm, 0.55 mm, 0.58 mm, 0.60 mm, etc.

[0143] As an example, it is assumed that the cross-sectional width W1 of the first connection segment 1021 of the N-pole conductive connector 1-1 provided in the embodiment of the present application is 0.6 mm, then the cross-sectional width W2 of the second connection segment 1022 is 0.514 mm, and the cross-sectional width W3 of the third connection segment 1023 is 0.343 mm.

[0144] Based on the above data, calculate the cost reduction of the N-pole conductive connector of the three-hole socket compared with the prior art as follows:

[0145] (1) The volume V of the N-pole conductive connector provided in the embodiment of the present application = 55 mm × 3.6 mm × 0.6 mm + 42 mm × 3.6 mm × 0.514 mm + 43 mm × 3.6 mm × 0.343 mm = 249.6 mm³.

[0146] (2) The volume V of the N-pole conductive connector provided by the prior art = 140 mm × 3.6 mm × 0.5 mm = 252 mm³.

[0147] It can be seen that the volume of the N-pole conductive connector provided in the embodiment of the present application is reduced by 2.4 mm³ compared with the prior art.

[0148] Taking the density of the N-pole conductive connector as 8.5 g / cm³ and the unit price as 41.14 yuan as an example, the reduction amount △M of the weight of the N-pole conductive connector provided in the embodiment of the present application compared with the prior art = 8.5 g / cm³ × 2.4 mm³ = 0.02 g, then the reduction amount △P of its cost compared with the prior art = 0.02 g × 41.14 yuan / kg = 0.008 yuan.

[0149] In summary, when the conductive connector provided in the embodiment of the present application is adopted, the material usage and cost of the conductive connector of a single three-hole socket are both significantly reduced compared with the prior art.

[0150] (2) As a second example, as shown in the attached Figure 8 and the attached Figure 9 The embodiment of the present application provides such a conductive connector, the cross-sectional widths of the three connection segments 102 it includes are the same, and the cross-sectional lengths decrease in sequence.

[0151] On the one hand, since the cost of the conductive connector provided by the embodiment of the present application must be less than that of the conductive connector provided by the prior art, the volume of the conductive connector provided by the embodiment of the present application is smaller than that of the conductive connector provided by the prior art; on the other hand, the ultimate life of the conductive connector provided by the embodiment of the present application must be greater than that of the conductive connector provided by the prior art, which makes the cross-sectional length of the first connection segment in the conductive connector provided by the embodiment of the present application greater than the cross-sectional length of the conductive connector provided by the prior art (the cross-sectional lengths of the conductive connectors provided by the prior art are the same as a whole).

[0152] Based on the above two aspects, the value range of the cross-sectional length L1 of the first connection segment in the conductive connector provided by the embodiment of the present application can be obtained, and any value within this value range can be used as the cross-sectional length of the first connection segment. After the cross-sectional length of the first connection segment is determined, according to the probability of the current flowing through each connection segment, the cross-sectional lengths L of the remaining connection segments m are also determined accordingly.

[0153] As shown in the Figure 8 attachment, for the N-pole conductive connector 1-1 provided by the embodiment of the present application, the cross-sectional width of each connection segment 102 is 0.5 mm, and the lengths of the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 are 55 mm, 42 mm, and 43 mm respectively.

[0154] Taking the N-pole conductive connector provided by the prior art as a comparison, it is set that the cross-sectional width of each connection segment is 0.5 mm, the cross-sectional length is 3.6 mm, and the lengths of the first connection segment, the second connection segment, and the third connection segment are 55 mm, 42 mm, and 43 mm respectively (the total length is 140 mm).

[0155] As shown in the Figure 9 attachment, for the L-pole conductive connector 1-2 provided by the embodiment of the present application, it is set that the cross-sectional width of each connection segment 102 is 0.5 mm, and the lengths of the first connection segment 1021, the second connection segment 1022, and the third connection segment 1023 are 44 mm, 42 mm, and 42 mm respectively.

[0156] Taking the L-pole conductive connector provided by the prior art as a comparison, it is set that the cross-sectional width of each connection segment is 0.5 mm, the cross-sectional length is 3.6 mm, and the lengths of the first connection segment, the second connection segment, and the third connection segment are 44 mm, 42 mm, and 42 mm respectively (the total length is 128 mm).

[0157] (2.1) For the L-pole conductive connector 1-2 provided by the embodiment of the present application, setting the cross-sectional length of its first connection segment 1021 as L1, it is calculated in the following way:

[0158] First, the volume of the L - pole conductive connector provided in the embodiment of the present application < the volume of the L - pole conductive connector provided by the prior art. This makes (0.5×L1×44)+(0.5×6 / 7×L1×42)+(0.5×4 / 7×L1×42) < (3.6×0.5×128). At this time, it is determined that L1 < 4.431 mm.

[0159] Second, the cross - sectional length of the first connection segment of the L - pole conductive connector provided in the embodiment of the present application > the cross - sectional length of the first connection segment of the L - pole conductive connector provided by the prior art. This makes L1 > 3.6 mm.

[0160] In summary, the value range of the cross - sectional length L1 of the first connection segment 1021 of the L - pole conductive connector 1 - 2 provided in the embodiment of the present application is: 3.6 mm < L1 < 4.431 mm. Any value within this range can be used as the cross - sectional length L1 of the first connection segment 1021 of the L - pole conductive connector 1 - 2. For example, 3.7 mm, 3.8 mm, 4.0 mm, 4.2 mm, etc.

[0161] According to the probability of the current flowing through each connection segment, determine the cross - sectional length L2 of the second connection segment 1022 and the cross - sectional length L3 of the third connection segment 1023 of the L - pole conductive connector 1 - 2. Their calculation formulas are as follows:

[0162] The cross - sectional length L2 of the second connection segment of the L - pole conductive connector provided in the embodiment of the present application = 6 / 7×L1, and the cross - sectional length L3 of the third connection segment = 4 / 7×L1.

[0163] As an example, if the cross - sectional length of the first connection segment 1021 of the L - pole conductive connector 1 - 2 provided in the embodiment of the present application is set to 3.8 mm, then the cross - sectional length of the second connection segment 1022 is 3.257 mm, and the cross - sectional length of the third connection segment 1023 is 2.171 mm.

[0164] Based on the above data, calculate the cost reduction of the L - pole conductive connector of the three - hole socket compared with the prior art as follows:

[0165] (1) The volume V of the L - pole conductive connector provided by the present application = (44 mm×3.8 mm×0.5 mm)+(42 mm×3.257 mm×0.5 mm)+(42 mm×2.171 mm×0.5 mm)=197.6 mm³.

[0166] (2) The volume V of the L - pole conductive connector provided by the prior art = 128 mm×3.6 mm×0.5 mm = 230.4 mm³.

[0167] It can be seen that the volume of the L - pole conductive connector provided by the embodiment of the present application is reduced by 32.8 mm³ compared with the prior art.

[0168] Taking the density of the L - pole conductive connector as 8.5 g / cm³ and the unit price as 41.14 yuan as an example, the reduction amount of the weight of the L - pole conductive connector provided by the embodiment of the present application compared with the prior art is △M = 8.5 g / cm³×32.8 mm³ = 0.279 g, and the reduction amount of its cost compared with the prior art is △P = 0.279 g×41.14 yuan / kg = 0.0115 yuan.

[0169] (2.2)For the N - pole conductive connector 1 - 1, according to the same method above, the value range of the cross - sectional length L1 of the first connection segment 1021 of the N - pole conductive connector 1 - 1 provided by the embodiment of the present application can be calculated as: 3.6 mm < L1 < 4.361 mm. Any value within this range can be used as the cross - sectional length L1 of the first connection segment 1021 of the N - pole conductive connector 1 - 1. For example, 3.7 mm, 3.8 mm, 4.0 mm, 4.2 mm, etc.

[0170] As an example, if the cross - sectional length L1 of the first connection segment 1021 of the N - pole conductive connector 1 - 1 is set to 3.8 mm, then the cross - sectional length L2 of the second connection segment 1022 is 3.257 mm, and the cross - sectional length L3 of the third connection segment 1023 is 2.171 mm.

[0171] Based on the above data, calculate the cost of the N - pole conductive connector of the three - hole socket as follows:

[0172] (1)The volume V of the N - pole conductive connector provided by the embodiment of the present application = 55 mm×3.8 mm×0.5 mm + 42 mm×3.257 mm×0.5 mm + 43 mm×2.171 mm×0.5 mm = 219.6 mm³.

[0173] (2)The volume V of the N - pole conductive connector provided by the prior art = 140 mm×3.6 mm×0.5 mm = 252 mm³.

[0174] It can be seen that the volume of the N - pole conductive connector provided by the embodiment of the present application is reduced by 32.4 mm³ compared with the prior art.

[0175] Taking the density of the N - pole conductive connector as 8.5 g / cm³ and the unit price as 41.14 yuan as an example, the reduction amount of the weight of the N - pole conductive connector provided by the embodiment of the present application compared with the prior art is △M = 8.5 g / cm³×32.4 mm³ = 0.275 g, and the reduction amount of its cost compared with the prior art is △P = 0.275 g×41.14 yuan / kg = 0.0113 yuan.

[0176] In summary, when the conductive connector provided by the embodiment of the present application is adopted, the material usage and cost of the conductive connector of a single three-hole socket are significantly reduced compared with the prior art.

[0177] (3) As Example 3, the embodiment of the present application provides such a conductive connector. Along the direction away from the terminal, the cross-sectional length and cross-sectional width of the three connection segments included therein both decrease successively.

[0178] The cross-sectional length and cross-sectional width of each connection segment can be determined respectively according to the probability of current flowing through each connection segment, wherein the values of the cross-sectional length and cross-sectional width of each connection segment can be determined according to its cross-sectional area.

[0179] Set the cross-sectional area of the first connection segment as S1. According to the probability of current flowing through each connection segment, determine the cross-sectional areas S of the remaining connection segments m = the probability P of current flowing through the current connection segment m × the cross-sectional area S1 of the first connection segment.

[0180] On the one hand, since the cost of the conductive connector provided by the embodiment of the present application must be less than the cost of the conductive connector provided by the prior art, this makes the volume of the conductive connector provided by the embodiment of the present application less than the volume of the conductive connector provided by the prior art; on the other hand, the ultimate life of the conductive connector provided by the embodiment of the present application must be greater than the ultimate life of the conductive connector provided by the prior art, this makes the cross-sectional area of the first connection segment in the conductive connector provided by the embodiment of the present application larger than the cross-sectional area of the first connection segment of the prior art conductive connector.

[0181] Based on the above two aspects, the value range of the cross-sectional area S1 of the first connection segment in the conductive connector provided by the embodiment of the present application can be obtained, and any value within this value range can be used as the cross-sectional area of the first connection segment. After the cross-sectional area of the first connection segment is determined, according to the probability of current flowing through each connection segment, the cross-sectional areas S1 of the remaining connection segments are also determined accordingly. Correspondingly, the width and cross-sectional width of each connection segment are also determined with the determination of the cross-sectional area.

[0182] (3.1) For S1 of the L-pole conductive connector provided by the embodiment of the present application, it is calculated in the following way:

[0183] Firstly, the volume of the L-pole conductive connector provided by the embodiment of the present application < the volume of the L-pole conductive connector provided by the prior art, this makes (S1×44)+(6 / 7×S1×42)+(4 / 7×S1×42) < (3.6×0.5×128), and it is determined that S1 < 2.215mm 2 .

[0184] Second, the cross-sectional area of the first connection segment of the L-pole conductive connector provided in the embodiment of the present application > the cross-sectional area of the first connection segment of the L-pole conductive connector provided in the prior art, which makes S1 > 1.8 mm 2 .

[0185] To sum up, the value range of the cross-sectional area S1 of the first connection segment of the L-pole conductive connector provided in the embodiment of the present application is: 1.8 mm 2 <S1<2.215 mm 2 , and any value within this range can be used as the cross-sectional area of the first connection segment of the L-pole conductive connector. For example, 1.9 mm 2 , 2 mm 2 , 2.1 mm 2 , 2.2 mm 2 , etc.

[0186] As an example, the cross-sectional area of the first connection segment of the L-pole conductive connector provided in the embodiment of the present application can be made 2.1 mm 2 , then the cross-sectional area of the second connection segment is 1.8 mm 2 , and the cross-sectional area of the third connection segment is 1.2 mm 2 .

[0187] According to the methods provided in the above Example 1 and Example 2, it can be determined that:

[0188] The value range of the cross-sectional width W1 of the first connection segment of the L-pole conductive connector provided in the embodiment of the present application is: 0.5 mm < W1 < 0.615 mm, and the value range of the cross-sectional length L1 is: 3.6 mm < L1 < 4.431 mm.

[0189] As an example, the cross-sectional length of the first connection segment of the L-pole conductive connector provided in the embodiment of the present application can be set to 3.8 mm, the cross-sectional width to 0.5526 mm, the cross-sectional length of the second connection segment to 3.5 mm, the cross-sectional width to 0.5143 mm, the width of the third connection segment to 3 mm, and the cross-sectional width to 0.4 mm.

[0190] Based on the above data, calculate the cost reduction of the L-pole conductive connector of the three-hole socket compared with the prior art as follows:

[0191] (1) The volume V of the L-pole conductive connector provided in the embodiment of the present application = (44 mm × 3.8 mm × 0.5526 mm) + (42 mm × 3.5 mm × 0.5143 mm) + (42 mm × 3 mm × 0.4 mm) = 218.4 mm³.

[0192] (2)The volume V of the L - pole conductive connector provided by the prior art is V = 128 mm × 3.6 mm × 0.5 mm = 230.4 mm³.

[0193] It can be seen that the volume of the L - pole conductive connector provided by the present application is reduced by 12 mm³ compared with the prior art.

[0194] Taking the density of the L - pole conductive connector as 8.5 g / cm³ and the unit price as 41.14 yuan as an example, the reduction amount △M of the weight of the L - pole conductive connector provided by the embodiment of the present application compared with the prior art is △M = 8.5 g / cm³ × 12 mm³ = 0.102 g. Then the reduction amount △P of its cost compared with the prior art is △P = 0.102 g × 41.14 yuan / kg = 0.0042 yuan.

[0195] (3.2)For S1 of the N - pole conductive connector provided by the embodiment of the present application, according to the same method above, the value range of the cross - sectional area S1 of the first connection segment of the N - pole conductive connector provided by the embodiment of the present application can be calculated as: 1.8 mm 2 <S1<2.180 mm 2 , any value within this range can be used as the cross - sectional area of the first connection segment of the N - pole conductive connector. For example, 1.9 mm 2 , 2 mm 2 , 2.1 mm 2 , 2.15 mm 2 etc.

[0196] As an example, the cross - sectional area of the first connection segment of the N - pole conductive connector provided by the embodiment of the present application can be made 2.1 mm 2 , then the cross - sectional area of the second connection segment is 1.8 mm 2 , and the cross - sectional area of the third connection segment is 1.2 mm 2 .

[0197] According to the methods provided in the above Example 1 and Example 2, it can be determined that:

[0198] The value range of the cross - sectional width W1 of the first connection segment of the N - pole conductive connector provided by the embodiment of the present application is: 0.5 mm < W1 < 0.606 mm, and the value range of the cross - sectional length L1 is: 3.6 mm < L1 < 4.361 mm.

[0199] As an example, the cross - sectional length of the first connection segment of the N - pole conductive connector provided by the embodiment of the present application can be set to 4 mm, and the cross - sectional width to 0.525 mm; the cross - sectional length of the second connection segment to 3 mm, and the cross - sectional width to 0.6 mm; the cross - sectional length of the third connection segment to 2.8 mm, and the cross - sectional width to 0.429 mm.

[0200] Based on the above data, calculate the cost reduction of the N - pole conductive connector of the three - hole socket compared with the prior art as follows:

[0201] (1) The volume V of the N - pole conductive connector provided in this embodiment is V=(55mm×4mm×0.525mm)+(42mm×3mm×0.6mm)+(42mm×2.8mm×0.429mm)=241.5mm³.

[0202] (2) The volume V of the N - pole conductive connector provided by the prior art is V = 140mm×3.6mm×0.5mm = 252mm³.

[0203] It can be seen that the volume of the L - pole conductive connector provided in the embodiment of this application is reduced by 10.5mm³ compared with the prior art.

[0204] Taking the density of the L - pole conductive connector as 8.5g / cm³ and the unit price as 41.14 yuan as an example, the reduction amount △M of the weight of the L - pole conductive connector provided in the embodiment of this application compared with the prior art is △M = 8.5g / cm³×10.5mm³ = 0.089, and the reduction amount △P of its cost compared with the prior art is △P = 0.089g×41.14 yuan / kg = 0.0036 yuan.

[0205] In summary, when using the conductive connector provided in the embodiment of this application, the material usage and cost of the conductive connector of a single three - hole socket are both reduced compared with the prior art.

[0206] In the state where each connection segment has a standard geometric size, it is also possible to change its resistance by changing the conductivity of the connection segment. In the embodiment of this application, among the multiple connection segments, the conductivity of the first connection segment adjacent to the wiring terminal of the socket is the largest. At the same time, the conductivities of the remaining connection segments can all be the same, or some can be the same, or they can be different from each other.

[0207] It should be noted that the above “each connection segment has a standard geometric size” means that on the premise that the number of holes in the multi - hole socket is determined, the geometric size of the connection segment corresponding to each hole in the N - pole connector and L - pole connector contained therein can be a determined standard value. According to the general standards in the art, the geometric size of each connection segment in the connector can be determined.

[0208] In a possible design, along the direction away from the wiring terminal, the conductivity of the multiple connection segments decreases in sequence.

[0209] Among them, the cross - sectional lengths (or cross - sectional widths) of the multiple connection segments in the conductive connector can be the same or different. For the convenience of molding preparation, the cross - sectional lengths of the multiple connection segments can be the same, and the cross - sectional widths can also be the same.

[0210] Taking a three - hole socket as an example, its conductive connecting piece includes a first connecting section, a second connecting section, and a third connecting section.

[0211] The material of the first connecting section can be red copper, the material of the second connecting section can be phosphor bronze, and the material of the third connecting section can be brass. The conductivity of the above three gradually decreases in the direction away from the terminal. This can balance the life differences of different connecting sections of the conductive connecting piece caused by different numbers of current flows, effectively improve the problem of the bucket effect existing in the life of the conductive connecting piece, and improve the overall life of the conductive connecting piece.

[0212] The above - mentioned connecting sections with different materials can be spliced by welding to form a whole conductive connecting piece.

[0213] In a possible design, any one of the above - mentioned provided in the embodiments of the present application can be a copper bar (see Figure 10 ) or can also be a multi - core wire (see Figure 11 , where Figure 11 only shows the outer sheath of the multi - core wire, and the wires inside are not shown).

[0214] Among them, the cross - sectional shape of the copper bar includes but is not limited to rectangle, circle, etc. In the embodiments of the present application, the cross - sectional shape of the copper bar is a rectangle.

[0215] For the conductive connecting piece with the above - mentioned structure, multiple connecting sections can be integrally formed or can also be connected in sequence by a splicing method, such as welding.

[0216] For the conductive connecting piece with the above - mentioned structure, the connecting sections can also be spliced by welding (such as soldering) to form an integral conductive connecting piece.

[0217] Taking the conductive connecting piece for a three - hole socket as an example, when it is a multi - core wire, the cross - sectional area ratio of the first connecting section, the second connecting section, and the third connecting section can be 7:6:4 (the diameters of the wires in each connecting section can be different, or the number of wires in each connecting section can be different), and the three wires with different cross - sectional areas are welded to form a conductive connecting piece.

[0218] The conductive connecting piece involved in the embodiments of the present application includes at least one of the N - pole conductive connecting piece 1 - 1 and the L - pole conductive connecting piece 1 - 2.

[0219] For a multi - hole socket, one of the N - pole conductive connecting piece 1 - 1 or the L - pole conductive connecting piece 1 - 2 can be improved in terms of resistance of each connecting section as described above, or both the N - pole conductive connecting piece 1 - 1 and the L - pole conductive connecting piece 1 - 2 can be improved in terms of resistance of each connecting section as described above.

[0220] In another aspect, an embodiment of the present application further provides a multi - socket, wherein the multi - socket includes any one of the conductive connectors involved in the embodiment of the present application.

[0221] Based on the improvement of the overall life of the adopted conductive connector, the service life of the multi - socket provided by the embodiment of the present application will also be correspondingly improved, reducing the probability of socket damage.

[0222] In the multi - socket provided by the embodiment of the present application, at least one of the L - pole conductive connector and the N - pole conductive connector adopts the conductive connector provided by the embodiment of the present application, and the improvement methods of the L - pole conductive connector and the N - pole conductive connector in terms of their resistance can be the same or different. As shown in the appendix Figure 10 shown, the conductive connector can be a copper bar; as shown in the appendix Figure 11 shown, the conductive connector can also be a multi - core wire.

[0223] The L - pole conductive connector and the N - pole conductive connector can adopt the same method to change the resistance of their respective connection segments. For example, both can adopt the method of changing the cross - sectional length or the cross - sectional width, or both can adopt the method of changing the material. To facilitate improving the preparation efficiency and simplifying the preparation process, the L - pole conductive connector and the N - pole conductive connector can adopt the same method to change the resistance of their respective connection segments.

[0224] The L - pole conductive connector and the N - pole conductive connector can also adopt different methods to change the resistance of their respective connection segments. For example, one can adopt the method of changing the cross - sectional length, while the other adopts the method of changing the cross - sectional width, or one can adopt the method of changing the cross - sectional length or the cross - sectional width, while the other adopts the method of changing the material.

[0225] The multi - socket provided by the embodiment of the present application has multiple holes. For example, it includes but is not limited to two - hole sockets, three - hole sockets, four - hole sockets, five - hole sockets, six - hole sockets, seven - hole sockets, eight - hole sockets, etc.

[0226] The types of the multi - socket provided by the embodiment of the present application include but are not limited to: two - pole sockets, three - pole sockets.

[0227] In a possible design, the multi - socket provided by the embodiment of the present application is a two - pole socket, also called a two - hole type socket. That is, the conductive connectors therein include an L - pole conductive connector and an N - pole conductive connector, and the plug sleeves of the two cooperate to form a two - hole type hole position. Among them, at least one of the L - pole conductive connector and the N - pole conductive connector adopts the conductive connector provided by the embodiment of the present application.

[0228] In one possible design, the multi-hole socket provided in the embodiments of the present application can be a three-pole socket, also known as a three-hole socket. That is, the conductive connector includes an L-pole conductive connector, an N-pole conductive connector, and an E-pole conductive connector, and the sockets of the three connectors cooperate to form a three-hole socket. At least one of the L-pole conductive connector and the N-pole conductive connector uses the conductive connector provided in the embodiments of the present application.

[0229] In one possible design, the multi-hole socket provided in the embodiments of the present application can be a two-pole + three-pole combination socket, where the conductive connector includes an L-pole conductive connector, an N-pole conductive connector, and an E-pole conductive connector, and the sockets of the three connectors cooperate to form a two-hole + three-hole socket configuration. At least one of the L-pole conductive connector and the N-pole conductive connector uses the conductive connector provided in the embodiments of the present application.

[0230] It is understandable that the structure of the multi-hole socket is common in the art. For example, as shown in the attached Figure 10 , Attachment Figure 11 and attached Figure 1 As shown, it may include: a shell 2; a socket seat 3 located on the shell 2; an N-pole terminal 4-1, an L-pole terminal 4-2, and an optional E-pole terminal 4-3 located on the shell 2; and an N-pole conductive connector 1-1, an L-pole conductive connector 1-2, and an optional E-pole conductive connector 1-3 fixed to the socket seat 3.

[0231] Among them, at least one of the N-pole conductive connector 1-1 and the L-pole conductive connector 1-2 adopts the conductive connector 1 involved in the embodiment of the present application, the N-pole conductive connector 1-1 is connected to the N-pole terminal 4-1, the L-pole conductive connector 1-2 is connected to the L-pole terminal 4-2, and optionally, the E-pole conductive connector 1-3 is connected to the E-pole terminal 4-3.

[0232] The N-pole conductive connector 1-1, the L-pole conductive connector 1-2, and the optional E-pole conductive connector 1-3 are all connected to multiple sockets through the socket contacts 101 thereon, wherein the multiple sockets on the N-pole conductive connector 1-1 and the L-pole conductive connector 1-2 correspond one to one and the corresponding sockets are spaced apart from each other, and multiple two-pole sockets can be formed to correspond to multiple hole positions.

[0233] Optionally, the multiple sockets on the E-pole conductive connector 1-3 correspond one-to-one to the multiple sockets on the N-pole conductive connector 1-1 and the L-pole conductive connector 1-2, and the corresponding sockets are spaced apart from each other, thereby forming a plurality of three-pole sockets.

[0234] Attachment Figure 1Illustrated is a three - stage socket with three hole positions. Among them, the N - pole conductive connector 1 - 1, the L - pole conductive connector 1 - 2, and the E - pole conductive connector 1 - 3 are respectively connected with an N - pole socket 5 - 1, an L - pole socket 5 - 2, and an E - pole socket 5 - 3 corresponding to the 1st hole position, the 2nd hole position, and the 3rd hole position. The N - pole socket 5 - 1, the L - pole socket 5 - 2, and the E - pole socket 5 - 3 at each hole position cooperate to form a three - stage socket at one hole position of the socket, and this three - stage socket can be inserted by a circuit wiring.

[0235] For the preparation of any conductive connector involved in the embodiments of the present application, the following preparation method can be referred to:

[0236] Obtain the size of the first connection segment in the conductive connector, and its obtaining method can, for example, refer to the methods described in the above Example 1, Example 2, or Example 3.

[0237] Further, according to the size of the first connection segment, determine the sizes of the remaining connection segments in the conductive connector.

[0238] Prepare the conductive connector according to the sizes of each connection segment.

[0239] Among them, according to the size of the first connection segment, determining the sizes of the remaining connection segments in the conductive connector may include the following:

[0240] According to the number of connection segments included in the conductive connector (i.e., the number of hole positions of the multi - hole socket), the connection segments through which the current flows in different hole - using situations can be determined, and further, the probability of the current flowing through each connection segment can be determined.

[0241] Since the ratio of the cross - sectional areas of the connection segments is proportional to the ratio of the probabilities of the current flowing through each connection segment, according to the size of the first connection segment and the probabilities of the current flowing through the remaining connection segments, the sizes of the remaining connection segments can be respectively calculated, and then used to guide the preparation of the conductive connector.

[0242] It can be understood that the number of connection segments in the conductive connector is the same as the number of hole positions of the multi - hole socket where it is located. For example, if it is m (m≥3), then when the user uses the socket, the number of hole - using states Y can be calculated by the following formula:

[0243] ;

[0244] For the above - mentioned number of hole - using states, determine the probability of the current flowing through each connection segment respectively. For example, the probability of the current flowing through the first connection segment is P1 = 1, the probability of the current flowing through the second connection segment is P2=(Y - 1) / Y, and the probability of the current flowing through the m - th connection segment is P m =X / Y. Just calculate the number of times X that the current flows through the m - th connection segment in the Y hole - using states, and then P can be obtained m。

[0245] Taking a common two - hole socket as an example, the probabilities that the current flows through the first connection segment and the second connection segment are 1 and 2 / 3 respectively.

[0246] Taking a common three - hole socket as an example, the probabilities that the current flows through the first connection segment, the second connection segment, and the third connection segment are 1, 6 / 7, and 4 / 7 respectively.

[0247] Taking a common four - hole socket as an example, the probabilities that the current flows through the first connection segment, the second connection segment, the third connection segment, and the fourth connection segment are 1, 14 / 15, 12 / 15, and 8 / 15 respectively.

[0248] Taking a common five - hole socket as an example, the probabilities that the current flows through the first connection segment, the second connection segment, the third connection segment, the fourth connection segment, and the fifth connection segment are 1, 30 / 31, 28 / 31, 24 / 31, and 16 / 31 respectively.
