[0032] In combination Figures 4 to 9 As shown in the drawings, two conductive modules 20 are respectively arranged in the inner cavity 11 of the insulating base 10. The two conductive modules 20 are separated by the partition plate 12 to prevent contact between the two conductive modules 20.

[0033] Specifically, each conductive module 20 includes a metal back plate 21, a terminal group, a fixing element 24 and a stepped metal plate 25. In the present application, the inner side of the metal back plate 21 refers to the side surface of the metal back plate 21 close to the center of the inner cavity 11 of the insulating base 10, that is, the side surface of the metal back plate 21 close to the partition plate 12, and the outer side of the metal back plate 21 refers to the side surface of the metal back plate 21 away from the center of the inner cavity 11 of the insulating base 10, that is, the side surface of the metal back plate 21 away from the partition plate 12.

[0034] The terminal group includes an inner side terminal sheet 22 and an outer side terminal sheet 23. The inner side terminal sheet 22 is attached to the inner side of the metal back plate 21 and is located between the inner side of the metal back plate 21 and the outer side terminal sheet 23. The outer side terminal sheet 23 has a gap between the inner side terminal sheet 22 and the outer side terminal sheet 23, and the front end of the outer side terminal sheet 23 is connected to the front end of the inner side terminal sheet 22.

[0035] The inner side terminal sheet 22 and the outer side terminal sheet 23 are integrally formed, which is convenient for manufacturing. Specifically, the inner side terminal sheet 22 and the outer side terminal sheet 23 are made of a metal sheet by bending and stamping.

[0036] The inner side terminal sheet 22 includes a plurality of inner strip-shaped terminals 221 spaced apart along the width direction thereof and an inner side mounting portion 222 attached to the inner side of the metal back plate 21. The direction of the spacing can also be along the length or other directions in addition to the width. It can be understood that the number of the inner strip-shaped terminals 221 can be set according to actual conditions. The core spirit of an example of the present application is to only separate the inner strip-shaped terminals 221 of the inner side terminal sheet 22 from the metal back plate 21, while retaining and increasing the area of the inner side mounting portion 222 in contact with the metal back plate 21, thereby improving the electrical properties between the two.

[0037] Each inner strip-shaped terminal 221 partially extends from the corresponding through hole 131 and is located in the insertion slot 13. Specifically, the front half of each inner strip-shaped terminal 221 extends from the corresponding through hole 131 and is located in the insertion slot 13.

[0038] The front end of each inner strip-shaped terminal 221 is L-shaped, and the inner contact portion 2211 of each inner strip-shaped terminal 221 at the right angle of the front end is located in the slot 13 and is used for contact and conduction with the corresponding contact terminal of the board end connector. The inner contact portion 2211 is located at the top end of the inner strip-shaped terminal 221. The top ends of the plurality of inner strip-shaped terminals 221 can be connected into a virtual inner side contact reference line 2212.

[0039] The inner side mounting portion 222 is provided with a plurality of inner side openings 223 along the width direction of the inner side mounting portion 222, and each inner side opening 223 corresponds to one inner strip-shaped terminal 221. The rear end of each inner strip-shaped terminal 221 is formed on the rear end inner wall of the corresponding inner side opening 223.

[0040] The outer side terminal sheet 23 includes a plurality of outer strip-shaped terminals 231, an outer side mounting portion 233, and a connecting portion 234, which are arranged along the width direction of the outer side terminal sheet 23. It can be understood that the number of outer strip-shaped terminals 231 can be set according to actual conditions.

[0041] The plurality of outer strip-shaped terminals 231 are connected between the outer side mounting portion 233 and the connecting portion 234, that is, the connecting portion 234 is connected to the front ends of the plurality of outer strip-shaped terminals 231, and the outer side mounting portion 233 is connected to the rear ends of the plurality of outer strip-shaped terminals 231, so that an outer side opening 232 is formed between two adjacent outer strip-shaped terminals 231. The outer side opening 232 separates the two adjacent outer strip-shaped terminals 231. In another example, the connecting portion 234 can be connected to the rear ends, side ends, or the like of the plurality of outer strip-shaped terminals 231, and the present application does not make further limitations thereon.

[0042] Each outer strip-shaped terminal 231 is partially extended from the corresponding through hole 131 and located in the slot 13. Specifically, except for the front end and the rear end of each outer strip-shaped terminal 231, the remaining part of each outer strip-shaped terminal 231 is extended from the corresponding through hole 131 and located in the slot 13.

[0043] The cross-sectional shape of the outer strip-shaped terminal 231 is V-shaped, and the outer contact portion 2311 of the outer strip-shaped terminal 231 is located at the V-shaped angle of the outer strip-shaped terminal 231 and is located in the slot 13 and is used for contact and conduction with the corresponding contact terminal of the board end connector. The outer contact portion 2311 is located at the top end of the outer strip-shaped terminal 231. The top ends of the plurality of outer strip-shaped terminals 231 can be connected into a virtual outer side contact reference line 2312.

[0044] The front end of the connecting portion 234 is connected to the front end of the inner side mounting portion 222 of the inner side terminal sheet 22.

[0045] Each inner strip terminal 221 corresponds to one outer side opening 232, and the front end of each inner strip terminal 221 respectively passes through the corresponding outer side opening 232 and protrudes from the outer terminal sheet 23 to expose the inner contact portion 2211. The portion of the inner strip terminal 221 protruding from the outer terminal sheet 23, i.e. the front end of the inner strip terminal 221 and the outer strip terminal 231, are not in contact.

[0046] As shown in FIG. 1, the inner contact portion 2211 of the plurality of inner strip terminals 221 is located between the front end of the outer terminal sheet 23 and the outer contact portion 2311 of the plurality of outer strip terminals 231. Figure 5

[0047] The inner contact portion 2211 of the plurality of inner strip terminals 221 is higher than the outer contact portion 2311 of the plurality of outer strip terminals 231, i.e. the distance from the inner contact portion 2211 of the plurality of inner strip terminals 221 to the inner side of the metal back plate 21 is greater than the distance from the outer contact portion 2311 of the plurality of outer strip terminals 231 to the inner side of the metal back plate 21.

[0048] It can be understood that in an alternative, the inner contact portion 2211 of the plurality of inner strip terminals 221 is at the same height as the outer contact portion 2311 of the plurality of outer strip terminals 231, i.e. the distance from the inner contact portion 2211 of the plurality of inner strip terminals 221 to the inner side of the metal back plate 21 is equal to the distance from the outer contact portion 2311 of the plurality of outer strip terminals 231 to the inner side of the metal back plate 21.

[0049] The outer side contact reference line 2312 and the inner side contact reference line 2212 are not in contact and are not staggered, which can be understood as the two-dimensional projection of the two reference lines 2312, 2212 on a horizontal virtual surface projected to a single height is completely non-overlapping. In the present embodiment, the height of the outer side contact reference line 2312 is slightly lower than the inner side contact reference line 2212, i.e. the outer side contact reference line 2312 is located below the inner side contact reference line 2212. In other embodiments, the outer side contact reference line 2312 is at the same height as the inner side contact reference line 2212. In this context, when referring to the specific physical quantity (e.g. height) of A and B as the same or similar, it is defined that the difference between the two maximum physical quantities is less than 5% or less of the maximum value of the larger one. For example, the heights of A and B are 100 mm and 99 mm respectively, the difference between the two is 1 mm, and 1 mm is less than 5% or less of 100 mm, so A and B can be said to be at the same height.

[0050] ​Through the above structure, the application designs the terminal group as the inner terminal sheet 22 and the outer terminal sheet 23, the inner terminal sheet 22 includes a plurality of inner strip-shaped terminals 221, the outer terminal sheet 23 includes a plurality of outer strip-shaped terminals 231, the inner strip-shaped terminals 221 and the outer strip-shaped terminals 231 belong to different terminal sheets, so that the contact area of the inner terminal sheet 22 with the metal back plate 21 is larger, so that the contact area of the terminal group with the metal back plate 21 is larger, the impedance is reduced, and the transmission of the current is ensured. In addition, it also has the characteristics of higher current, lower voltage drop, lower impedance and temperature rise, etc. The unique structure of the terminal can transmit large current at high speed, while increasing the reliability and the number of plug-in times, and reducing the terminal insertion force.

[0051] The fixing element 24 penetrates the outer mounting portion 233 of the outer terminal sheet 23, the inner mounting portion 222 of the inner terminal sheet 22, the metal back plate 21 and the stepped metal plate 25 to fix the terminal group on the inner side of the metal back plate 21 and fix the stepped metal plate 25 on the outer side of the metal back plate 21.

[0053] In this embodiment, the number of fixing elements 24 is two, and it can be understood that the number of fixing elements 24 can also be other, which can be set according to the actual situation.

[0054] The top end and the bottom end of the stepped metal plate 25 are respectively provided with two clamping positions 251. One of the two clamping positions 251 of one conductive module 20 is respectively buckled with one buckle 15 on the top wall and one buckle 15 on the bottom wall of the inner cavity 11 of the insulating base 10, and the other of the two clamping positions 251 of the other conductive module 20 is respectively buckled with the other buckle 15 on the top wall and the other buckle 15 on the bottom wall of the inner cavity 11 of the insulating base 10. Through the buckling of the buckle 15 and the clamping position 521, the two conductive modules 20 are conveniently arranged in the inner cavity 11 of the insulating base 10.

[0055] Each cable group 30 includes a plurality of first cables 31 and a plurality of second cables 32, and the number of the first cables 31 and the second cables 32 can be set according to actual conditions. The first cables 31 and the second cables 32 are the same in size. One end of the plurality of first cables 31 is welded on the outer side of the corresponding metal back plate 21 and located between the stepped metal plate 25 and the outer side of the metal back plate 21, so as to realize electrical connection with the metal back plate 21, and the other end extends from the rear end of the insulating base 10.
