Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a power connector, a power terminal assembly and a connector combination. Background Art

[0002] PwrMAX power connectors are ideal for high-end data, telecommunications, and industrial equipment applications, providing power to systems requiring high density and high current.

[0003] Please refer to U.S. Patent Publication No. US7905731B2, which discloses an electrical connector with stress-distributing features. The contacts have a first half and a second half, each of which has alternating straight contact beams and angled contact beams. When the first half and the second half are assembled, the straight contact beams of the first half combine with the straight contact beams of the second half to form a straight contact beam pair, and the angled contact beams of the first half combine with the angled contact beams of the second half to form an angled contact beam pair. When the electrical connector is mated with a docking connector, the straight contact beam pair of the electrical connector inserts into the angled contact beam pair of the docking connector, and the straight contact beam pair of the docking connector inserts into the angled contact beam pair of the electrical connector.

[0004] However, when the electrical connector is mated with the docking connector, the first and second halves of the contacts are susceptible to separation. For example, when the straight contact beams of the docking connector are inserted into the angled contact beams of the electrical connector, the angled contact beams of the electrical connector are forced to open a certain distance. Consequently, the main bodies of the first and second halves of the electrical connector are also easily forced to open along with the angled contact beams. Although the first and second halves are secured together by the mating holes of the first and second halves, the risk of separation cannot be completely avoided.

[0005] Furthermore, if one of the straight contact beams in a pair of straight contact beams is not perfectly flat, a gap will form between the two straight contact beams. If the straight contact beam pair is not aligned with the angled contact beam pair during mating, one straight contact beam may enter the angled contact beam pair while the other straight contact beam does not. This means that the two straight contact beams will be forced to open further apart, forcing the main body of the first half and the main body of the second half to also open apart.

[0006] The above situations will cause irreversible damage to the electrical connector and the docking connector.

[0007] Therefore, it is necessary to provide a safer and more reliable power transmission structure that can provide power services for high-density and high-current systems. Utility Model Content

Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," refer only to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0070] The connector assembly of the present invention includes a power connector and a docking connector that can be docked. The power connector can be referred to as a female connector, while the docking connector can be referred to as a male connector. Of course, the power connector can also be referred to as a male connector, while the docking connector can be referred to as a female connector. Alternatively, without distinguishing between male and female connectors, the power connector can be referred to as a first power connector, while the docking connector can be referred to as a second power connector.

[0071] The power connector of the utility model can solve the problem that the structure of the existing power terminal assembly is unstable and affects the current transmission. The power connector of the utility model can provide stable current conduction capability.

[0072] The following embodiments illustrate the power connector of the present invention using a right-angle power connector as an example, wherein the plugging direction is parallel to the circuit board. The power connector of the present invention may also be a vertical power connector, wherein the plugging direction is perpendicular to the circuit board. The power connector of the present invention may also be a power connector with other angles, wherein the plugging direction is inclined relative to the circuit board.

[0073] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, the power connector 1 of the present invention includes an insulating base 10 and at least one power terminal assembly 20 disposed in the insulating base 10. The power terminal assembly 20 includes a first power terminal 21 and a second power terminal 22 that are combined together to transmit power. In this embodiment, the first power terminal 21 and the second power terminal 22 are combined together by being assembled together in the terminal channel 101 of the insulating base 10 and clamped by the side walls of the terminal channel 101. In other embodiments, the first power terminal 21 and the second power terminal 22 can also be combined together by providing a convex or concave snap-in structure (not shown) on the first power terminal 21 and the second power terminal 22, respectively.

[0074] Please refer to Figure 4 、 Figure 5 、 Figure 6a 、 Figure 6b In the illustrated power terminal assembly 20, the first power terminal 21 includes a first body 210 having a first mating side 2101 and at least one clamping structure 211 disposed on the first mating side 2101; the clamping structure 211 includes two opposing clamping beams 212. The second power terminal 22 includes a second body 220 having a second mating side 2201 and at least one insertion structure 221 disposed on the second mating side 2201; the insertion structure 221 includes a first straight beam 222 and a second straight beam 223 formed by folding in half. The first body 210 and the second body 220 are parallel to each other and abut against each other, secured together within the insulating base 10, with the clamping structure 211 and the insertion structure 221 arranged in a row.

[0075] In this embodiment, the first power terminal 21 includes a plurality of the clamping structures 211, and the second power terminal 22 includes a plurality of the insertion structures 221. The plurality of the clamping structures 211 and the plurality of the insertion structures 221 are arranged alternately along the vertical direction. Of course, in other embodiments, the plurality of the clamping structures 211 and the plurality of the insertion structures 221 may also be arranged alternately along the horizontal direction.

[0076] In this embodiment, since the power connector 1 of the present invention is a right-angle type, the clamping structure 211 and the insertion structure 221 are arranged in a row along the vertical direction. In other embodiments, when the power connector 1 of the present invention is an upright type, the clamping structure 211 and the insertion structure 221 are arranged in a row along the horizontal direction.

[0077] The present invention provides a clamping structure 211 on the first power terminal 21 and an insertion structure 221 on the second power terminal 22, so that they will not affect each other during docking and will not cause separation of the first power terminal 21 and the second power terminal 22. Therefore, the power terminal assembly 20 of the present invention has a stable structure and a safe docking function, and can provide stable current conduction capability for the power connector 1 of the present invention, thereby improving its service life.

[0078] The structure and advantages of the power terminal assembly 20 and the power connector 1 of the present invention will be described in more detail below.

[0079] Please refer to Figure 6b 、 Figure 7aAs shown, the clamping structure 211 includes a sheet 213, two side wings 214 located on both sides of the sheet 213, and an opening 215 located between the two side wings 214. The sheet 213 and the side wings 214 are perpendicular to the first main body 210, and the sheet 213 is vertically connected to the first docking side 2101 of the first main body 210. Specifically, the sheet 213 is vertically connected to the first docking side 2101 of the first main body 210 through a bending section 216. The two clamping beams 212 are symmetrically arranged on the two side wings 214 and are approximately perpendicular to the side wings 214. Specifically, the clamping beams 212 are formed by bending the side wings 214. Each clamping beam 212 has a contact portion 2120 and a guide portion 2121, Figure 7a From the top view shown, the contact portions 2120 face each other, and the guide portion 2121 is located at the free end of the clamping beam 212 and extends away from the opening 215. Figure 7c It can be seen that the contact portion 2120 and the guiding portion 2121 are located below the opening 215 .

[0080] In this embodiment, if Figure 7a 、 Figure 7b 、 Figure 7c As shown, the first body 210 is a vertical plate; the sheet 213 is a horizontal sheet, which is perpendicular to the first body 210. The clamping beam 212 is formed by the side wing 214 along an oblique line L (see the label Figure 7a ) is bent vertically downward and approximately perpendicular to the sheet 213. The clamping beam 212 is also bent horizontally outward away from the opening 215 to form the contact portion 2120 and the guide portion 2121. Thus, it can be seen that the clamping structure 211 is formed through multiple bends. For example, the sheet 213 is formed through one vertical bend, and the clamping beam 212 is formed through two vertical bends. Of course, during the stamping and bending process, these bends can be completed simultaneously or sequentially.

[0081] In this embodiment, if Figure 7aAs shown, the width of the opening 215 is set to gradually decrease in the direction away from the first docking side 2101. A clamping opening 2122 is formed between the contact portions 2120 of the two clamping beams 212 to provide elastic clamping and electrical contact functions. A guide opening 2123 is formed between the guide portions 2121 of the two clamping beams 212 to provide a guiding effect. The guide opening 2123, the clamping opening 2122 and the opening 215 are connected. The width of the guide opening 2123 is greater than the width of the clamping opening 2122. The width of the clamping opening 2122 is less than the width of the opening 215, in particular, less than the minimum width of the opening 215. During docking, the docking terminal assembly 60 of the docking connector 2 enters the clamping opening 2122 from the guide opening 2123 , and the two contact portions 2120 of the two clamping beams 212 are forced to open. Finally, the docking terminal assembly 60 is accommodated in the clamping opening 2122 and the opening 215 .

[0082] Please refer to Figure 6a 、 Figure 6b 、 Figure 7a 、 Figure 7b 、 Figure 7c As shown, the insert structure 221 also includes a folded section 224 connecting the first straight beam 222 and the second straight beam 223. The folded section 224 is located at the end of the insert structure 221 away from the second mating side 2201, folding the first straight beam 222 and the second straight beam 223. The provision of the folded section 224 in the insert structure 221 of the present invention not only allows the first straight beam 222 and the second straight beam 223 to be folded, but also allows the first straight beam 222 and the second straight beam 223 to be smoothly inserted into the mating terminal assembly 60 during mating, thereby achieving a secure docking effect.

[0083] Specifically, the insert structure 221 is formed by a folding process to form the first straight beam 222, the second straight beam 223, and the folded section 224. The folded section 224 is a column with a circular arc cross-section. The first straight beam 222 and the second straight beam 223 are approximately parallel. It is important to note that the so-called folding process refers to a 180-degree bend or a bend close to 180 degrees. In practice, due to the influence of the bending process or the terminal material, even if a 180-degree bend is performed, the first straight beam 222 and the second straight beam 223 are unlikely to be completely parallel, but rather roughly folded. The cross-section of the folded section 224 can be approximately semicircular. In practice, as long as the folded section 224 can keep the first straight beam 222 and the second straight beam 223 roughly folded in half, the insert structure 221 can function as a secure docking device.

[0084] In this embodiment, one end of the first straight beam 222 is connected to the second docking side 2201 , and the other end is connected to the folded section 224 ; one end of the second straight beam 223 is connected to the folded section 224 , and the other end is a free end 2230 .

[0085] like Figure 7a As shown, the length of the second straight beam 223 is greater than that of the first straight beam 222. Therefore, the free end 2230 of the second straight beam 223 extends backward, exceeds the first straight beam 222, and abuts against the side of the second body 220 facing the first power terminal 21.

[0086] Please refer to Figure 6a 、 Figure 6b As shown, the first mating side 2101 of the first power terminal 21 is further provided with at least one first connecting structure 217, and the second mating side 2201 of the second power terminal 22 is further provided with at least one second connecting structure 225. When the first power terminal 21 and the second power terminal 22 are combined, the first body 210 and the second body 220 are parallel and abutted together, the sheet 213 is connected to the second connecting structure 225, and the free end 2230 of the second straight beam 223 is connected to the first connecting structure 217. This increases the rigidity of the clamping structure 211 and the insertion structure 221 in the mating direction, improves their mating strength, prevents misalignment during mating, and further enhances the mating security of the power terminal assembly 20. Furthermore, the connection of the sheet 213 to the second connecting structure 225 and the connection of the second straight beam 223 to the first connecting structure 217 further improves the power transmission efficiency between the first power terminal 21 and the second power terminal 22.

[0087] In this embodiment, the first power terminal 21 includes a plurality of alternately arranged clamping structures 211 and a plurality of alternately arranged first connecting structures 217 (e.g., three clamping structures 211 and two alternately arranged first connecting structures 217). Accordingly, the second power terminal 22 includes a plurality of alternately arranged insertion structures 221 and a plurality of alternately arranged second connecting structures 225 (e.g., two alternately arranged insertion structures 221 and three alternately arranged second connecting structures 225). When the first power terminal 21 and the second power terminal 22 are combined, the clamping structures 211 connect to the corresponding second connecting structures 225, and the insertion structures 221 connect to the corresponding first connecting structures 217. The clamping structures 211 and the insertion structures 221 are alternately arranged in a row to transmit power together.

[0088] In this embodiment, the first connecting structure 217 is a vertical edge of the first main body 210, for example, referred to as a first vertical edge 2170 (see reference numeral 2170). Figure 6b The second connecting structure 225 is a vertical edge of the second main body 220, for example, referred to as the second vertical edge 2250 (see reference numerals Figure 6b ). Accordingly, the edge of the free end 2230 of the second straight beam 223 is vertically shaped to mate with the first vertical edge 2170. The abutting edge of the sheet 213 is horizontally straight and is configured to mate with the second vertical edge 2250. In other embodiments, the first connecting structure 217 and the second connecting structure 225 may also have arcuate edges or other shapes, and the edge of the free end 2230 of the second straight beam 223 and the abutting edge of the sheet 213 may be modified accordingly, so that they mate with each other during connection.

[0089] In other embodiments, the length of the second straight beam 223 can also be equal to the length of the first straight beam 222. As long as the free end 2230 of the second straight beam 223 can be connected to the first connecting structure 217, the docking strength of the insertion structure 221 can be improved. It should also be noted that for docking security considerations, the length of the second straight beam 223 should not be less than (and can be slightly less than) the length of the first straight beam 222 to ensure that the second straight beam 223 has a sufficiently long electrical contact interval or a sufficiently large contact area.

[0090] Please refer to Figure 6b As shown, in this embodiment, in addition to the first docking side 2101, the first body 210 also has a first fixed side 2102, a first installation side 2103 and a first tail side 2104. The first docking side 2101 is arranged in parallel with the first tail side 2104, the first fixed side 2102 and the first installation side 2103 are arranged in parallel, and the first fixed side 2102 and the first installation side 2103 are perpendicular to the first docking side 2101. More specifically, the front edge of the first body 210 serves as the first docking side 2101, and the first connecting structure 217 can be directly served by the front edge of the first body 210. In addition, in this embodiment, the front edge of the first body 210 is vertical (such as Figure 7a shown).

[0091] The first power terminal 21 also includes a plurality of pins 218 arranged in a row. In this embodiment, the pins 218 are disposed on the first mounting side 2103 and extend downward, for mounting on a circuit board (not shown). The first power terminal 21 also includes a fixing structure for securing the first power terminal 21 to the insulating base 10. The fixing structure includes a shoulder 2191 disposed on the first fixing side 2102 and a plurality of protrusions 2192 disposed on the first fixing side 2102 and the first mounting side 2103.

[0092] Similarly, in this embodiment, in addition to the second docking side 2201, the second body 220 also has a second fixed side 2202, a second mounting side 2203, and a second tail side 2204. The second docking side 2201 is arranged in parallel with the second tail side 2204, the second fixed side 2202 and the second mounting side 2203 are arranged in parallel, and the second fixed side 2202 and the second mounting side 2203 are perpendicular to the second docking side 2201. More specifically, the front edge of the second body 220 serves as the second docking side 2201, so the second connecting structure 225 can be directly served by the front edge of the second body 220. In addition, in this embodiment, the front edge of the second body 220 is rectangular tooth-shaped (such as Figure 7a As shown), the second connecting structure 225 is located in the recess of the front edge.

[0093] The second power terminal 22 also includes a plurality of pins 228 arranged in a row. In this embodiment, the pins 228 are disposed on the second mounting side 2203 and extend downward for mounting on a circuit board (not shown).

The fixing structure includes a shoulder 2291 disposed on the second fixing side 2202 and a plurality of protrusions 2292 disposed on the second fixing side 2202 and the second mounting side 2203.

[0094] The following will introduce Figure 8a 、 Figure 8b Another embodiment of the power terminal assembly 20a of the present invention is shown. The elements or structures in this other embodiment are similar to those in Figure 6a 、 Figure 6b Similar elements or similar structures in the illustrated embodiments share the same reference numerals and are additionally suffixed with a.

[0095] Please refer to Figure 8aThe second power terminal 22a shown in the figure, the insertion structure 221a is formed by a folding process to form a first straight beam 222a, a second straight beam 223a and a folded section 224a. The first straight beam 222a and the second straight beam 223a are not completely parallel, and there is an angle A between them (see the reference numerals). Figure 8b Furthermore, the second straight beam 223a is provided with a power connection section 2231 located at or near the free end 2230a of the second straight beam 223a. The thickness of the power connection section 2231 is thinner than the thickness of other areas of the second straight beam 223a. More specifically, the side of the second body 220a facing the second power terminal 22a is thinned at or near the free end 2230a of the second straight beam 223a, thereby forming the power connection section 2231. Therefore, the power connection section 2231 can be referred to as a thinned section.

[0096] In addition, Figure 8a In the illustrated embodiment, the second connection structure 225a is a vertical edge of the second body 220a (referred to as a second vertical edge 2250a ).

[0097] Please refer to Figure 8a As shown in the first power terminal 21a, the first connecting structure 217a includes at least one power connecting piece 2171, and the power connecting piece 2171 protrudes forward from a vertical edge of the first main body 210a (which can be referred to as the first vertical edge 2170a) in a direction substantially perpendicular to the first docking side 2101a. In fact, the power connecting piece 2171 is slightly inclined relative to the first main body 210a and is inclined toward the second power terminal 22a to facilitate the subsequent formation of a reliable connection with the power connecting section 2231. The thickness of the power connecting piece 2171 is less than the thickness of the first main body 210a. Therefore, the power connecting piece 2171 can be referred to as a thinning piece. In this embodiment, the power connecting piece 2171 and the first main body 210a are made integrally.

[0098] Please combine Figure 8a and Figure 8bAs shown, when the first power terminal 21a and the second power terminal 22a are combined, the power connection section 2231 faces the power connection piece 2171, and the clamping structure 211a is connected to the second connection structure 225a. When the power terminal assembly 20a is docked with a docking terminal assembly (not shown), the power connection section 2231 moves toward the power connection piece 2171 and connects to it. The free end 2230a of the second straight beam 223a may or may not abut the first vertical edge 2170a.

[0099] exist Figure 8a 、 8b In the illustrated embodiment, the present invention, by providing the power connection piece 2171 and the power connection section 2231, can form a more complete power transmission path between the first power terminal 21a and the second power terminal 22a, thereby improving power transmission efficiency. Furthermore, since both the power connection section 2231 and the power connection piece 2171 are designed to be thinner, the mating stability or fit between the power connection section 2231 and the power connection piece 2171 is improved while maintaining the thickness of the combined first and second power terminals.

[0100] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, the power connector 1 of the utility model includes a plurality of the power terminal assemblies 20 .

[0101] The power connector 1 of the present invention also includes a plurality of other power terminal assemblies. If the power terminal assembly 20 is referred to as the first type power terminal assembly 20, then the other power terminal assemblies can be referred to as the second type power terminal assembly 30, which has a different structure from the first type power terminal assembly 20. In detail, Figure 3 As shown, each second type power terminal assembly 30 includes two symmetrically arranged power terminals 301, with multiple pairs of elastic beams 302 formed at the front ends of the two power terminals. Each pair of elastic beams 302 has a pair of external contact portions 3020 facing away from each other.

[0102] The power connector 1 of the present invention further includes a signal terminal module 40 . The signal terminal module 40 includes a plurality of signal terminals 41 arranged in at least one row and a fixing seat 42 for fixing the signal terminals 41 .

[0103] In this embodiment, if Figure 3As shown, the first type power terminal assembly 20 and the second type power terminal assembly 30 are respectively arranged on both sides of the signal terminal module 40 .

[0104] Please refer to Figure 3 As shown, the insulating base 10 of the present invention includes a docking port 100 and three groups of terminal channels 101, 102, and 103. The docking port 100 is located at the front end of the insulating base 10, and the three groups of terminal channels 101, 102, and 103 pass through the docking port 100, the rear surface of the insulating base 10, and the bottom surface of the insulating base 10. The three groups of terminal channels 101, 102, and 103 are used to respectively accommodate and fix the first type power terminal assembly 20, the second type power terminal assembly 30, and the signal terminal 41, wherein the clamping structure 211 and the insertion structure 221 of the first type power terminal assembly 20, the elastic beam 302 of the second type power terminal assembly 30, and the front end docking section of the signal terminal 41 all enter the docking port 100; the pins 218, 228 of the first type power terminal assembly 20, the pins of the second type power terminal assembly 30, and the pins of the signal terminal 41 all extend out of the bottom surface of the insulating base 10; the first type power terminal assembly 20 and the second type power terminal assembly 30 are both locked in the insulating base 10 by their respective fixing structures; and the signal terminal 41 is fixed in the insulating base 10 by the fixing seat 42.

[0105] In addition, if Figure 3 As shown, the insulating base 10 of the present invention is also provided with a plurality of first heat dissipation holes 104 and a plurality of second heat dissipation holes 105. The first heat dissipation holes 104 are distributed on the top and bottom surfaces of the insulating base 10 and correspond to the positions of the docking port 100; the second heat dissipation holes 105 are distributed on the top surface of the insulating base 10 and are located near its rear surface. The insulating base 10 of the present invention is also provided with two symmetrical guide channels 106, distributed on both sides of the docking port 100, to guide the docking connector 2 to be accurately inserted into the docking port 100.

[0106] The structure and advantages of the docking connector 2 and the connector assembly 3 of the present invention will be described in detail below.

[0107] Please refer to Figure 9 、 Figure 10 、 Figure 11 As shown, the docking connector 2 of the present invention includes a docking base 50 and at least one docking terminal assembly 60 disposed in the docking base 50 .

[0108] Please refer to Figure 12 、 Figure 13 、 Figure 14As shown, the docking terminal assembly 60 includes a third power terminal 61 and a fourth power terminal 62 that are combined together to transmit power. The structure of the docking terminal assembly 60 is substantially the same as that of the power terminal assembly 20. For example, the docking terminal assembly 60 includes at least one clamping structure 611 provided on the third power terminal 61 and at least one inserting structure 621 provided on the fourth power terminal 62. Figure 14 As shown, the clamping structure 611 includes two clamping beams 612 arranged opposite to each other; and the inserting structure 621 includes a third straight beam 622 and a fourth straight beam 623 formed by folding in half.

[0109] The main difference between the docking terminal assembly 60 and the power terminal assembly 20 lies in the different positions and numbers of the clamping structures 211, 611 and the inserting structures 221, 621. This is to ensure that the two can be plugged in and out of each other. For example, in this embodiment, the power terminal assembly 20 has three clamping structures 211 and two inserting structures 221, while the docking terminal assembly 60 has three inserting structures 621 and two clamping structures 611.

[0110] Of course, in other embodiments, the structure of the docking terminal assembly 60 may be substantially the same as that of the power terminal assembly 20a, which will not be described in detail here.

[0111] Please refer to Figure 15 and Figure 16 In the connector assembly 3 shown, when the power connector 1 and the docking connector 2 are docked, the insertion structure 221 of the power terminal assembly 20 matches the clamping structure 611 of the docking terminal assembly 60, and the insertion structure 621 of the docking terminal assembly 60 matches the clamping structure 211 of the power terminal assembly 20, forming electrical conduction for common power transmission. Figure 6b and Figure 14 As shown, the first straight beam 222 and the second straight beam 223 of the power terminal assembly 20 are inserted between the two clamping beams 612 of the docking terminal assembly 60, and the third straight beam 622 and the fourth straight beam 623 of the docking terminal assembly 60 are inserted between the two clamping beams 212 of the power terminal assembly 20.

[0112] Please refer again Figure 11 As shown, in this embodiment, the docking connector 2 of the present invention includes a plurality of docking terminal assemblies 60 .

[0113] The docking connector 2 of the present invention also includes a plurality of other docking terminal assemblies. If the above-mentioned docking terminal assembly 60 is referred to as the third type power terminal assembly 60, then the other docking terminal assemblies can be referred to as the fourth type power terminal assembly 70, which has a different structure from the third type power terminal assembly 60. In detail, Figure 11 As shown, each of the fourth type power terminal assemblies 70 includes two symmetrically arranged docking terminals 701 , and multiple pairs of sheet beams 702 are formed at the front ends of the two docking terminals 701 . Each pair of sheet beams 702 has a pair of inner contact portions 7020 facing each other.

[0114] The docking connector 2 of the present invention further includes a docking signal terminal module 80, which is arranged between the third-type power terminal assembly 60 and the fourth-type power terminal assembly 70. The docking signal terminal module 80 includes a plurality of docking signal terminals 81 arranged in at least one row and a docking fixing seat 82 for fixing the docking signal terminals 81.

[0115] In addition, if Figure 11 As shown, the docking base 50 is also provided with an insertion section 500 located at the front end and three groups of docking terminal channels 501, 502, and 503. The docking terminal channels 501, 502, and 503 pass through the front surface of the insertion section 500, the rear surface of the docking base 50, and the bottom surface of the docking base 50, and are used to respectively accommodate and fix the third type power terminal assembly 60, the fourth type power terminal assembly 70, and the docking signal terminal 81.

[0116] When the power connector 1 and the docking connector 2 are docked, Figure 16 As shown, the insertion section 500 of the docking base 50 enters the docking port 100 of the insulating base 10, and the insertion structure 221 and clamping structure 211 of the first-type power terminal assembly 20 respectively dock with the clamping structure 611 and insertion structure 621 of the third-type power terminal assembly 60, forming electrical conduction. Furthermore, the elastic beam 302 of the second-type power terminal assembly 30 (particularly the outer contact portion 3020 of the elastic beam 302) docks with the sheet beam 702 of the fourth-type power terminal assembly 70 (particularly the inner contact portion 7020 of the sheet beam 702), forming electrical conduction. The signal terminal 41 is electrically connected to the docking signal terminal 81 for signal transmission.

[0117] Please refer to Figure 11As shown, the docking base 50 of the present invention is further provided with a plurality of third heat dissipation holes 504, distributed on the top and bottom surfaces of the insertion section 500, and extending through the docking terminal channels 501 and 502 for accommodating the third type power terminal assembly 60 and the fourth type power terminal assembly 70. The docking base 50 of the present invention is also provided with two symmetrical guide posts 505, distributed on both sides of the insertion section 500, to guide the docking connector 2 to be accurately inserted into the docking port 100.

[0118] In summary, because the clamping structure 211 and the inserting structure 221 are disposed on two different power terminals (e.g., the first power terminal 21 and the second power terminal 22), the two clamping beams 212, when forced apart, do not cause the two power terminals 21 and 22 to separate, and the first straight beam 222 and the second straight beam 223, formed by folding in half, do not separate upon docking. Therefore, the power connector 1 and the connector assembly 3 of the present invention have a secure docking function, can provide the power connector 1 with stable current conduction capability, and extend its service life.
