[0006] An insulating body, the insulating body including a first mating surface and a first mating slot penetrating the first mating surface, the first mating slot being configured to receive a mating module; and

[0007] A first power terminal module is fixed to the insulating body. The first power terminal module includes a first power terminal and a second power terminal. The first power terminal includes a first main body, a first elastic arm extending from the first main body, and a first tail extending from the first main body. The first elastic arm includes a first mating portion protruding into the first mating slot. The second power terminal includes a second main body, a second elastic arm extending from the second main body, and a second tail extending from the second main body. The second elastic arm includes a second mating portion protruding into the first mating slot. The first main body and the second main body are spaced apart along a first direction. The first mating portion and the second mating portion are spaced apart along a second direction, and the first direction and the second direction are perpendicular to each other.

[0008] The second elastic arm is provided with a first protrusion that protrudes toward the first power terminal along the first direction;

[0009] When the docking module is not inserted into the first docking slot, the first raised portion and the first power terminal have a first gap in the first direction, so that the first raised portion and the first power terminal do not contact each other.

[0010] When the docking module is inserted into the first docking slot and is in place, the second elastic arm is abutted by the docking module and deforms toward the first power terminal, thereby causing the first raised portion to contact the first power terminal in the first direction.

[0011] As a further improvement of the present invention, both the first docking portion and the second docking portion are arc-shaped; the protrusion direction of the first docking portion is the same as the protrusion direction of the second docking portion, and both are opposite to the protrusion direction of the first raised portion.

[0012] As a further improvement of the present invention, the first tail portion and the second tail portion are spaced apart along a third direction, wherein the third direction is perpendicular to the first direction and the second direction.

[0013] As a further improved technical solution of the present invention, the first main body includes a first base, the first elastic arm extends integrally from the first base, the first base has a first center line, the first docking part has a second center line, and the first center line and the second center line are arranged in a staggered manner.

[0014] The second main body includes a second base, and the second elastic arm extends integrally from the second base. The second base has a third center line, and the second docking portion has a fourth center line. The third center line and the fourth center line are arranged in a staggered manner.

[0015] As a further improvement of the present invention, the first power terminal module includes a space between the first elastic arm and the second elastic arm along the first direction.

[0016] As a further improvement of the present invention, the first docking part and the second docking part are located at the same height.

[0017] As a further improved technical solution of the present invention, the first main body includes a first base and a first bent portion bent from the first base, the first elastic arm extends integrally from the first base, and the first tail extends integrally from the first bent portion.

[0018] The second main body includes a second base and a second bent portion bent from the second base, the second elastic arm extends integrally from the second base, and the second tail extends integrally from the second bent portion;

[0019] When the docking module is inserted into the first docking slot and is in place, the first raised portion abuts against the first base portion.

[0020] As a further improved technical solution of the present invention, the first main body includes a first base, and the first elastic arm extends integrally from the first base;

[0021] The second main body includes a second base, and the second elastic arm extends integrally from the second base. The first raised portion has a first inclined portion and a second inclined portion, wherein the first inclined portion and the second base have an included angle α, where 0°<α≤65°.

[0022] As a further improvement of the present invention, the insulating body includes a first mounting surface opposite to the first mating surface, a plurality of terminal mounting slots penetrating the first mounting surface, and an abutting surface exposed in the plurality of terminal mounting slots. The plurality of terminal mounting slots are connected to the first mating slot, and the abutting surface is in contact with at least a portion of the first main body.

[0023] As a further improved technical solution of the present invention, both the first elastic arm and the second elastic arm have a structure that is wide at the root and narrow at the free end.

[0024] Compared to existing technologies, the second elastic arm of this invention has a first raised portion protruding towards the first power terminal along the first direction. When the docking module is not inserted into the first docking slot, the first raised portion and the first power terminal have a first gap in the first direction, so that the first raised portion does not contact the first power terminal, thereby producing a relatively weak insertion feel. When the docking module is inserted into the first docking slot and is fully inserted, the second elastic arm is abutted by the docking module and deforms towards the first power terminal, so that the first raised portion contacts the first power terminal in the first direction, thereby producing a relatively strong insertion feel. At the same time, by the first raised portion abutting against the first power terminal, the first power terminal and the second power terminal are connected in series, which is beneficial for transmitting a relatively large current.

[0053] In the embodiment illustrated in the present invention, the plurality of first power terminal modules 2 are fixed to the insulating body 1, and each first power terminal module 2 is identical. The following detailed description uses only one first power terminal module 2 as an example.

[0054] Please combine Figures 8 to 13 As shown, the first power terminal module 2 includes a first power terminal 21 and a second power terminal 22. The first power terminal 21 includes a first main body portion 211, a first elastic arm 212 integrally extending from the first main body portion 211, and a first tail portion 213 integrally extending from the first main body portion 211. The first elastic arm 212 includes a first mating portion 2121 protruding into the first mating slot 110.

[0055] The second power terminal 22 includes a second main body 221, a second elastic arm 222 integrally extending from the second main body 221, and a second tail portion 223 integrally extending from the second main body 221. The second elastic arm 222 includes a second mating portion 2221 protruding into the first mating slot 110.

[0056] The first main body portion 211 and the second main body portion 221 are spaced apart along a first direction D1-D1 (e.g., vertical direction). The first docking portion 2121 and the second docking portion 2221 are spaced apart along a second direction D2-D2 (e.g., horizontal direction). The first tail portion 213 and the second tail portion 223 are spaced apart along a third direction D3-D3 (e.g., front-back direction). The first direction D1-D1 and the second direction D2-D2 are perpendicular to each other, and the third direction D3-D3 is perpendicular to both the first direction D1-D1 and the second direction D2-D2.

[0057] The second elastic arm 222 is provided with a first protrusion 224 protruding toward the first power terminal 21 along the first direction D1-D1. The first protrusion 224 has a first inclined portion 2241, a second inclined portion 2242, and an arcuate portion 2243 connecting the first inclined portion 2241 and the second inclined portion 2242.

[0058] Please combine Figure 17 as well as Figure 19As shown, when the docking module 200 is not inserted into the first docking slot 110, the first raised portion 224 and the first power terminal 21 have a first gap g1 in the first direction D1-D1, so that the first raised portion 224 and the first power terminal 21 do not contact each other.

[0059] Please combine Figure 18 as well as Figure 20 As shown, when the docking module 200 is inserted into the first docking slot 110 and is in place, the second elastic arm 222 is abutted by the docking module 200 and deforms toward the first power terminal 21, so that the first protrusion 224 contacts the first power terminal 21 in the first direction D1-D1.

[0060] The first main body 211 is L-shaped and includes a flat first base 2111 and a first bent portion 2112 bent from the first base 2111. The first elastic arm 212 extends integrally from the first base 2111, and the first tail 213 extends integrally from the first bent portion 2112. In the illustrated embodiment of the invention, an R-angle is formed at the connection between the first elastic arm 212 and the first base 2111 to improve the elasticity of the first elastic arm 212. In the illustrated embodiment of the invention, a plurality of first tails 213 of a first power terminal 21 are spaced apart along the second direction D2-D2, and the first tails 213 are used for soldering to the circuit board 300. In the illustrated embodiment of the invention, when the docking module 200 is inserted into the first docking slot 110 and is in place, the first protrusion 224 abuts against the first base 2111. When the first power terminal 21 is installed in the corresponding terminal mounting slot 15, the abutting surface 151 is at least partially in contact with the first main body 211. This configuration allows the insulating body 1 to abut and limit the first power terminal 21 after the docking module 200 is inserted, preventing improper warping of the first power terminal 21 (e.g., preventing a seesaw effect).

[0061] Please combine Figure 8 As shown, in a first embodiment of the first power terminal module 2 of the present invention, there are two first elastic arms 212 of the first power terminal 21, and the two first elastic arms 212 are spaced apart along the second direction D2-D2, with a first gap 1 between the two first elastic arms 212. The first base 2111 has a first center line C1, and the first mating portion 2121 has a second center line C2, with the first center line C1 and the second center line C2 being staggered.

[0062] The second main body 221 is L-shaped, including a flat second base 2211 and a second bent portion 2212 bent from the second base 2211. The second elastic arm 222 extends integrally from the second base 2211, and the second tail 223 extends integrally from the second bent portion 2212. In the illustrated embodiment of the present invention, there are multiple second tails 223 of one second power terminal 22, spaced apart along the second direction D2-D2, and the second tails 223 are used for soldering to the circuit board 300. In the illustrated embodiment of the present invention, the first inclined portion 2241 and the second base 2221 have an included angle α, where 0° < α ≤ 65°. This arrangement helps to maintain the elasticity of the second elastic arm 222 and avoids yielding (i.e., loss of good elasticity).

[0063] In a first embodiment of the first power terminal module 2 of the present invention, the second power terminal 22 has two second elastic arms 222, which are spaced apart along the second direction D2-D2, and a second gap 2 is provided between the two second elastic arms 222. The distance between the two first elastic arms 212 and the two second elastic arms 222 is a third gap 3, wherein the first gap 1 is the same as the second gap 2, and both are greater than the third gap 3. The second base 2211 has a third center line C3, and the second mating portion 2221 has a fourth center line C4, wherein the third center line C3 and the fourth center line C4 are staggered.

[0064] In the embodiment illustrated in the present invention, both the first elastic arm 212 and the second elastic arm 222 have a structure that is wide at the root and narrow at the free end. This arrangement helps to achieve a balance between maintaining elasticity and maintaining the largest possible terminal area.

[0065] Please combine Figure 9 As shown in the illustrated embodiment of the present invention, the first power terminal module 2 includes a gap space 2120 located along the first direction D1-D1 between the first elastic arm 212 and the second elastic arm 222. This arrangement avoids mutual interference between the first elastic arm 212 and the second elastic arm 222.

[0066] In the embodiment illustrated in the present invention, both the first docking portion 2121 and the second docking portion 2221 are arc-shaped; the protrusion direction of the first docking portion 2121 is the same as the protrusion direction of the second docking portion 2221, and both are opposite to the protrusion direction of the first raised portion 224. The first docking portion 2121 and the second docking portion 2221 are located at the same height.

[0067] The second power terminal module 3 includes a third power terminal 31 and a fourth power terminal 32. The third power terminal 31 includes a third main body portion 311, a third elastic arm 312 integrally extending from the third main body portion 311, and a third tail portion 313 integrally extending from the third main body portion 311. The third elastic arm 312 includes a third mating portion 3121 protruding into the first mating slot 110.

[0068] The fourth power terminal 32 includes a fourth main body 321, a fourth elastic arm 322 integrally extending from the fourth main body 321, and a fourth tail portion 323 integrally extending from the fourth main body 321. The fourth elastic arm 322 includes a fourth mating portion 3221 protruding into the first mating slot 110.

[0069] The third main body portion 311 and the fourth main body portion 321 are spaced apart along a first direction D1-D1 (e.g., vertical direction). The third docking portion 3121 and the fourth docking portion 3221 are spaced apart along a second direction D2-D2 (e.g., horizontal direction). The third tail portion 313 and the fourth tail portion 323 are spaced apart along a third direction D3-D3 (e.g., front-back direction).

[0070] The fourth elastic arm 322 is provided with a second protrusion 324 that protrudes toward the third power terminal 31 along the first direction D1-D1.

[0071] When the docking module 200 is not inserted into the first docking slot 110, the second raised portion 324 and the third power terminal 31 have a second gap in the first direction D1-D1 (compare with the first gap g1), so that the second raised portion 324 and the third power terminal 31 do not contact each other.

[0072] When the docking module 200 is inserted into the first docking slot 110 and is in place, the fourth elastic arm 322 is abutted by the docking module 200 and deforms toward the third power terminal 31, so that the second protrusion 324 contacts the third power terminal 31 in the first direction D1-D1.

[0073] In the illustrated embodiment of the present invention, the first main body portion 211, the second main body portion 221, the fourth main body portion 321, and the third main body portion 311 are arranged at intervals along the first direction D1-D1. The first tail portion 213, the second tail portion 223, the fourth tail portion 323, and the third tail portion 313 are arranged at intervals along the third direction D3-D3. Partial structures of the first elastic arm 212 and the third elastic arm 312 are symmetrically arranged on both sides of the first mating slot 110, and partial structures of the second elastic arm 222 and the fourth elastic arm 322 are symmetrically arranged on both sides of the first mating slot 110.

[0074] Please combine Figures 4 to 7 As shown, the plurality of conductive terminals 4 are mounted and fixed in the plurality of terminal receiving slots 16. Each conductive terminal 4 includes a resilient contact portion 41 extending into the second mating slot 120 and a tail portion 42 extending out of the insulating body 1. The tail portion 42 is used for mounting on the circuit board 300. In the embodiment illustrated in the present invention, the resilient contact portions 41 of the plurality of conductive terminals 4 are arranged in two rows on both sides (e.g., the upper and lower sides) of the second mating slot 120. The resilient contact portions 41 are configured to contact the third conductive sheet 203 of the mating module 200. Depending on different application requirements, the plurality of conductive terminals 4 can be power terminals and / or signal terminals.

[0075] Please combine Figures 14 to 16 As shown, in the second embodiment of the first power terminal module 2 of the present invention, there is only one first elastic arm 212 of the first power terminal 21 and only one second elastic arm 212 of the second power terminal 22.

[0076] Compared to the prior art, the second elastic arm 222 of the present invention has a first protrusion 224 protruding towards the first power terminal 21 along the first direction D1-D1. When the docking module 200 is not inserted into the first docking slot 110, the first protrusion 224 and the first power terminal 21 have a first gap g1 in the first direction D1-D1, so that the first protrusion 224 does not contact the first power terminal 21, thereby producing a relatively weak insertion feel. In other words, when the docking module 200 is just inserted, the insertion force is small, which is conducive to the insertion of the docking module 200. When the docking module 200 is inserted into the first docking slot 110 and is fully inserted, the second elastic arm 222 is abutted by the docking module 200 and deforms towards the first power terminal 21, so that the first protrusion 224 contacts the first power terminal 21 in the first direction D1-D1, thereby producing a relatively strong insertion feel. In other words, as the docking module 200 is further inserted, the insertion force is greater, thereby improving the contact reliability between the docking module 200 and the power terminal. At the same time, the first protrusion 224 abuts against the first power terminal 21, connecting the first power terminal 21 and the second power terminal 22 in series, which is beneficial for transmitting a relatively large current.
