The second connection assembly 44 is fixedly mounted on the second plate 412 of the first adapter plate 41 and the fourth plate 422 of the second adapter plate 42, so that the first connection assembly 43 on the first substrate 112 and the second substrate 122 can be pluggably connected to the second connection assembly 44 on the second plate 412 and the fourth plate 422 along the front-to-back direction D1 (connection direction). Since the adapter module 4 is connected between the bus bar assembly 1 and the connected bus bar assembly 3, the first connection assembly 43 and the second connection assembly 44 of the adapter module 4 can be pluggably connected to make the disassembly process between the bus bar assembly 1 and the connected bus bar assembly 3 quick and convenient, which is conducive to maintenance operations.

Referring to FIG. 3 and FIG. 6 to FIG. 9 , in the first embodiment, the first connection assembly 43 includes a plurality of sockets 430, and the second connection assembly 44 includes a plurality of plugs 440. The sockets 430 and the plugs 440 are used to be pluggable and floatably connected to each other along the front-to-back direction D1 (connection direction). For example, the plugs 440 and the sockets 430 are made of copper material that can flow large currents and has good heat dissipation. However, it should be noted that in other embodiments, the first connection assembly 43 may include a plurality of plugs 440, and the second connection assembly 44 may include a plurality of sockets 430, or the first connection assembly 43 may include a plurality of sockets 430 and a plurality of plugs 440, and the second connection assembly 44 may include a plurality of plugs 440 and a plurality of sockets 430, and the sockets 430 and plugs 440 of the first connection assembly 43 may be pluggable and floatably docked with the plugs 440 and sockets 430 of the second connection assembly 44 along the front-rear direction D1 (docking direction). Therefore, the present invention should not be limited to the first embodiment.

The socket 430 includes a base 431 and a contact unit 432. The contact unit 432 includes a barrel 433, two pressure-applying elements 434, a contact 435, and a fixing ring 436. The plug 440 has a plug post 440a, and the plug post 440a is used to be inserted into the socket 430 along the front-to-back direction D1 and contact the contact 435. The base 431 is annular and has a channel 431a extending along the front-to-back direction D1 between two ends and an annular receiving groove 431b extending outward from the channel 431a. The barrel-shaped member 433 has a barrel body 433a with an outer diameter smaller than the channel 431a, and an annular flange 433b extending outward from the outer wall surface of the barrel body 433a, and the annular flange 433b is movably accommodated in the annular receiving groove 431b. The two pressure-applying elements 434 are elastic and are disposed between the annular flange 433b of the barrel-shaped member 433 and the annular receiving groove 431b, so that the barrel-shaped member 433 can float in the channel 431a. In detail, in the first embodiment, the two pressure-applying elements 434 are wave spring rings and are respectively arranged on the two end surfaces of the annular flange 433b in the front-rear direction D1, so that the barrel-shaped member 433 can float radially in the channel 431a (that is, float on the plane formed by the left-right direction D2 and the up-down direction D3) and float along the front-rear direction D1, but in other embodiments, the pressure-applying elements 434 can be other existing elastic elements that can be used to apply pressure, and the number of the pressure-applying elements 434 can be one or more than three, and is not limited to the first embodiment.

The contact piece 435 is disposed in the barrel body 433a of the barrel-shaped piece 433 and is provided for the pin 440a of the plug 440 to extend therethrough. The contact piece 435 has an annular head portion 435a disposed on the inner wall surface of the barrel body 433a adjacent to one end edge of the barrel body 433a, and a plurality of elastic contact pieces 435b extending from the annular head portion 435a toward the other end edge of the barrel body 433a and inwardly obliquely for contacting the pin 440a. The fixing ring 436 and the barrel body 433a of the barrel-shaped member 433 jointly clamp the annular head 435a of the contact member 435 to fix the contact member 435 in the barrel-shaped member 433. Specifically, the fixing ring 436 has a clamping portion 436a which is annular and jointly clamps the annular head 435a of the contact member 435 with the inner wall surface of the barrel body 433a, and a resting portion 436b which extends outward from the end edge of the clamping portion 436a and rests against the end edge of the barrel body 433a. Specifically, since the pin 440a of the plug 440 penetrates and contacts the contact 435 of the socket 430 along the front-to-back direction D1, the pin 440a of the plug 440 can also float in the front-to-back direction D1 relative to the contact 435 of the socket 430. Since the first connection assembly 43 and the second connection assembly 44 of the adapter module 4 are floatably connected to each other, the floating requirement between the bus bar assembly 1 and the connected bus bar assembly 3 can be met.

Referring to FIGS. 10 to 14 , a second embodiment of the electrical connection device 100 of the present invention is different from the first embodiment in that the first adapter board 41 has a plate body 413 fixed to the first docking bus bar 31 by, for example, screws 45 and extending along the docking direction, and the second adapter board 42 has a plate body 413 fixed to the second docking bus bar 32 by, for example, screws 45 and extending along the docking direction. The second connection assembly 44 includes a plurality of sockets 441 fixed to the outer side surface of the plate body 413 of the first adapter board 41 and the outer side surface of the plate body 413 of the second adapter board 42.

In the second embodiment, the bottoms of the first conductive plate 437 and the second conductive plate 438 are located lower than the bottoms of the first substrate 112 and the second substrate 122. The plugs 439 on the first conductive plate 437 and the second conductive plate 438 are arranged in a row along a vertical direction D3 perpendicular to the front-rear direction D1 (mating direction), and the plugs 439 have a pin 439a extending along the front-rear direction D1 (mating direction) and floatingly mating with the corresponding socket 430 along the front-rear direction D1 (mating direction). Since the plugs 439 are disposed on the first conductive plate 437 and the second conductive plate 438, the number of the plugs 439 arranged in a row is not limited by the height of the first substrate 112 and the second substrate 122 in the vertical direction D3, and can be arranged extending downward along the first conductive plate 437 and the second conductive plate 438 (in other embodiments, they can also be arranged extending upward). In a variant embodiment, the first conductive plate 437 and the second conductive plate 438 can also be omitted, and the first connection assembly 43 only includes a plurality of plugs 439 fixed to the first substrate 112 and the second substrate 122, and the plugs 439 on the first substrate 112 and the second substrate 122 are arranged in a row along the vertical direction D3.

In addition, the sockets 441 on the plate body 413 of the first adapter plate 41 are arranged along the up-down direction D3, and are divided into two rows along the front-to-back direction D1 (mating direction). The two rows of sockets 441 on the plate body 413 of the first adapter plate 41 are staggered with each other in the up-down direction D3, and the projections projected onto the first substrate 112 along the front-to-back direction D1 (mating direction) partially overlap with each other. The sockets 441 on the plate body 423 of the second adapter plate 42 are arranged along the up-down direction D3, and are divided into two rows along the front-to-back direction D1 (mating direction). The two rows of sockets 441 on the plate body 423 of the second adapter plate 42 are staggered with each other in the up-down direction D3, and the projections projected onto the second substrate 122 along the front-to-back direction D1 (mating direction) partially overlap with each other, thereby reducing the space occupied by the sockets 441 on the first adapter plate 41 and the second adapter plate 42 along the up-down direction D3, thereby reducing the overall height in the up-down direction D3.

Referring to FIG. 10 and FIG. 15 to FIG. 18 , the socket 441 includes a seat body 442 fixed to the board surface of the board body 413 and having a rectangular parallelepiped structure, and a contact unit 443. The seat body 442 has a channel 442a extending along the front-rear direction D1 between two ends, and an annular receiving groove 442b extending outward from the channel 442a. The contact unit 443 is disposed in the channel 442a, and the pin 439a of the plug 439 is used to dock with the contact unit 443 of the socket 430. In the second embodiment, the seat body 442 includes a first seat portion 442c and a second seat portion 442d connected by multiple fixing members 442e such as rivets. The first seat portion 442c has a mounting protrusion 442f inserted into the plate body 413 of the first adapter plate 41 or the plate body 423 of the second adapter plate 42 and screwed fixed by a screw member 442g, and two positioning columns 442h inserted into the plate body 413 of the first adapter plate 41 or the plate body 423 of the second adapter plate 42 to produce a positioning effect. However, it should be noted that the seat body 442 can also be fixed to the plate body 413 of the first adapter plate 41 and the plate body 423 of the second adapter plate 42 by other means such as welding or snap-fitting, and is not limited to the second embodiment.

The contact unit 443 includes a barrel-shaped member 444, two pressure-applying elements 445, a contact member 446, and a fixing ring 447. The barrel-shaped member 444 has a barrel body 444a with an outer diameter smaller than the channel 442a, and an annular flange 444b extending outward from the outer wall surface of the barrel body 444a, and the annular flange 444b is movably accommodated in the annular receiving groove 442b. The two pressure-applying elements 445 are elastic and are disposed between the annular flange 444b of the barrel-shaped member 444 and the annular receiving groove 442b, so that the barrel-shaped member 444 can float in the channel 442a. In detail, in the second embodiment, the two pressure-applying elements 445 are wave spring rings and are respectively arranged on the two end surfaces of the annular flange 444b in the front-rear direction D1, so that the barrel-shaped member 444 can float radially in the channel 442a (that is, float on the plane formed by the left-right direction D2 and the up-down direction D3) and float along the front-rear direction D1, but in other embodiments, the pressure-applying elements 445 can be other existing elastic elements that can be used to apply pressure, and the number of the pressure-applying elements 445 can be one or more than three, and is not limited to the second embodiment.

The contact piece 446 is disposed in the barrel body 444a of the barrel-shaped piece 444 and is provided for the pin 439a of the plug 439 to extend therethrough. The contact piece 446 has an annular head portion 446a disposed on the inner wall surface of the barrel body 444a adjacent to one end edge of the barrel body 444a, and a plurality of elastic contact pieces 446b extending from the annular head portion 446a toward the other end edge of the barrel body 444a and inwardly obliquely for contacting the pin 439a. The fixing ring 447 and the barrel body 444a of the barrel-shaped member 444 jointly clamp the annular head 446a of the contact member 446 to fix the contact member 446 in the barrel-shaped member 444. Specifically, the fixing ring 447 has a clamping portion 447a which is annular and jointly clamps the annular head 446a of the contact member 446 with the inner wall surface of the barrel body 444a, and a resting portion 447b which extends outward from the end edge of the clamping portion 447a and rests against the end edge of the barrel. In detail, since the pin 439a of the plug 439 penetrates into and contacts the contact 446 of the socket 441 along the front-to-back direction D1, the pin 439a of the plug 439 can also float in the front-to-back direction D1 relative to the contact 446 of the socket 441.

In summary, the adapter module 4 of the electrical connection device 100 of the present invention is connected between the bus bar assembly 1 and the docking bus bar assembly 3. The first connection assembly 43 and the second connection assembly 44 of the adapter module 4 are pluggable, so that the disassembly process between the bus bar assembly 1 and the docking bus bar assembly 3 is fast and convenient, which is conducive to maintenance operations. In addition, since the first connection assembly 43 and the second connection assembly 44 of the adapter module 4 are floatably docked with each other, the floating requirements between the bus bar assembly 1 and the docking bus bar assembly 3 can be met.
