Abstract
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] Regarding existing power connectors, please refer to U.S. Patent Publication No. US7905731B2, which discloses an electrical connector with stress distribution 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 another connector, the straight contact beam pair of the first connector will insert into the angled contact beam pair of the other connector, and the straight contact beam pair of the other connector will insert into the angled contact beam pair of the first connector.
[0004] However, in actual situations, if two straight contact beams are combined into a straight contact beam pair, the two straight contact beams need to have a very high degree of flatness in order to achieve complete contact with each other. Once one of the straight contact beams does not have good flatness, a gap will be formed between the two straight contact beams. During plugging, it is very likely that the two straight contact beams (i.e., the straight contact beam pair) will not be able to align or even be inserted into the gap between the angled contact beam pair of the other connector, resulting in docking failure. In addition, as long as one of the straight contact beams does not have good flatness, the straight contact beam pair may deviate from the original docking center and damage the angled contact beam pair. For example, the angled contact beam pair may be asymmetrically stretched, which will cause one of the angled contact beams to be excessively deformed, thereby affecting current conduction and the life of the contacts.
[0005] Therefore, it is necessary to provide a new power connector and a power terminal assembly thereof, which can provide safe and reliable 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.
[0063] 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.
[0064] The power connector of the utility model can solve the problems of docking failure and excessive deformation of existing power terminal components during docking, and the power connector of the utility model can provide stable current conduction capability.
[0065] 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.
[0066] 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 connect with the docking terminal assembly 60 (see FIG. Figure 10 ) to jointly transmit power.
[0067] like Figure 4 、 Figure 5 、 Figure 6a 、 Figure 6b As shown, the first power terminal 21 includes a first body 210 having a first mating side 2101, at least one first curved oblique beam 211 disposed on the first mating side 2101, and at least one folded straight beam 212 disposed on the first mating side 2101. The second power terminal 22 includes a second body 220 having a second mating side 2201, and at least one second curved oblique beam 221 disposed on the second mating side 2201. The first body 210 and the second body 220 are parallel to each other and abut against each other and are fixed together in the insulating base 10. The first curved oblique beam 211 and the second curved oblique beam 221 are disposed opposite each other to form a pair of clamping beams, while the folded straight beam 212 serves as an insertion beam.
[0068] The present invention avoids the risk of unsafe docking in the prior art by designing the power terminal assembly 20 with a folded straight beam 212 serving as an insertion beam. The present invention's power terminal assembly 20 and its power connector 1 offer a stable structure, secure docking, stable current conduction, and a longer service life.
[0069] 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.
[0070] Please refer to Figure 6a 、 Figure 6b As shown, in this embodiment, the first body 210 of the first power terminal 21 is a vertical plate. In addition to the first mating side 2101, the first body 210 further has a first fixed side 2102, a first mounting side 2103, and a first tail side 2104. The first mating side 2101 is arranged parallel to the first tail side 2104, and the first fixed side 2102 and the first mounting side 2103 are arranged parallel to each other. The first fixed side 2102 and the first mounting side 2103 are perpendicular to the first mating side 2101. More specifically, in this embodiment, the vertical front edge of the first body 210 serves as the first mating side 2101, the vertical rear edge of the first body 210 serves as the first tail side 2104, the horizontal upper edge of the first body 210 serves as the first fixed side 2102, and the horizontal lower edge of the first body 210 serves as the first mounting side 2103.
[0071] like Figure 6a and Figure 6b As shown, on the first docking side 2101, the first curved oblique beam 211 has a first expansion portion 2110, a first contact portion 2111, and a first guide portion 2112. The first expansion portion 2110 is connected to the first docking side 2101 and is first bent away from the second power terminal 22 and then bent toward the second power terminal 22. The first contact portion 2111 is away from the first docking side 2101 and is formed by bending away from the second power terminal 22. The first guide portion 2112 is located at the free end of the first curved oblique beam 211 and extends in a direction away from the second power terminal 22.
[0072] like Figure 6a and Figure 6bAs shown, on the first docking side 2101, the folded straight beam 212 has a first straight portion 2120, a second straight portion 2121 folded onto the first straight portion 2120, and a folded portion 2123 connecting the first straight portion 2120 and the second straight portion 2121. More specifically, one end of the first straight portion 2120 is connected to the first docking side 2101, and the other end is connected to the folded portion 2123; one end of the second straight portion 2121 is connected to the folded portion 2123, and the other end is free.
[0073] Specifically, the folding straight beam 212 is formed by a folding process to form the first straight portion 2120, the second straight portion 2121, and the folding portion 2123. The folding portion 2123 is a column with a circular arc cross-section. It should be emphasized that the so-called folding process refers to a 180-degree bending process or a bending process close to 180 degrees. In fact, due to the influence of the bending process or the terminal material, after folding, the first straight portion 2120 and the second straight portion 2121 are not completely parallel or parallel, but are roughly folded. The cross-section of the folding portion 2123 of the present invention can be close to a semicircular shape. In fact, as long as the folding portion 2123 can make the first straight portion 2120 and the second straight portion 2121 roughly folded, the folding straight beam 212 has the function of safe docking.
[0074] The present invention provides a folding portion 2123 at the front end of the folding straight beam 212 to ensure that the folding straight beam 212 is safely inserted into the docking terminal assembly 60, thereby achieving safe docking.
[0075] In this embodiment, the length of the second straight portion 2121 is greater than that of the first straight portion 2120. Therefore, the free end of the second straight portion 2121 extends backward, exceeds the first straight portion 2120, and abuts against the side of the first body 210 facing the second power terminal 22.
[0076] In this embodiment, the first power terminal 21 includes a plurality of first curved oblique beams 211 and a plurality of folded straight beams 212 (e.g., three first curved oblique beams 211 and two folded straight beams 212), which are alternately arranged. The present invention does not limit the specific number of the first curved oblique beams 211 and the folded straight beams 212.
[0077] In addition, if Figure 6a and Figure 6bAs shown, the first power terminal 21 further includes a plurality of pins 213 arranged in a row. In this embodiment, the pins 213 are disposed on the first mounting side 2103 and extend downward for mounting on a circuit board (not shown). The first power terminal 21 further includes a fixing structure for securing the first power terminal 21 to the insulating base 10. The fixing structure may be a shoulder 214 disposed on the first fixing side 2102 and a plurality of protrusions 215 disposed on the first fixing side 2102 and the first mounting side 2103.
[0078] Please refer to Figure 6a 、 Figure 6b As shown, in this embodiment, the main difference between the second power terminal 22 and the first power terminal 21 is that the second power terminal 22 is not provided with the folded straight beam 212 .
[0079] Specifically, the second body 220 of the second power terminal 22 is also a vertical plate. In addition to the second mating side 2201, the second body 220 further has a second fixing side 2202, a second mounting side 2203, and a second tail side 2204. The second mating side 2201 is arranged parallel to the second tail side 2204, and the second fixing side 2202 and the second mounting side 2203 are arranged parallel to each other. The second fixing side 2202 and the second mounting side 2203 are perpendicular to the second mating side 2201.
[0080] On the second docking side 2201, the second curved oblique beam 221 has a second expansion portion 2210, a second contact portion 2211, and a second guide portion 2212. The second expansion portion 2210 is connected to the second docking side 2201 and is first bent away from the first power terminal 21 and then bent toward the first power terminal 21. The second contact portion 2211 is away from the second docking side 2201 and is bent away from the first power terminal 21. The second guide portion 2212 is located at the free end of the second curved oblique beam 221 and extends away from the first power terminal 21.
[0081] like Figure 6a and Figure 6bAs shown, the second power terminal 22 further includes at least one recess 222 disposed on the second mating side 2201. The recess 222 corresponds to the folded straight beam 212 of the first power terminal 21 and is configured to accommodate a portion of the folded straight beam 212, such as the second straight portion 2121 of the folded straight beam 212. The depth of the recess 222 can be determined based on the length of the second straight portion 2121. Specifically, when the first power terminal 21 and the second power terminal 22 are combined, the second straight portion 2121 is located within the recess 222, with the free end of the second straight portion 2121 connected to a side 2220 of the recess 222. Specifically, the recess 222 can be a square recess 222 with a vertical side 2220, or a circular recess 222 with a circular side 2220. Of course, the side edges 2220 of the notch 222 may be directly formed by the vertical front edge of the second body 220 , and it is not necessary to form the side edges 2220 by recessing the vertical front edge of the second body 220 inward.
[0082] In this embodiment, since the free end of the second straight portion 2121 of the first power terminal 21 is substantially square, the recess 222 is configured as a square recess 222 with vertical sides, so that the two can match.
[0083] By abutting the second straight portion 2121 of the first power terminal 21 against the notch 222 of the second power terminal 22, the present invention increases the rigidity of the folded straight beam 212, improves its docking strength, and prevents the folded straight beam 212 from shifting during docking, thereby further enhancing docking security of the folded straight beam 212. Furthermore, by connecting the second straight portion 2121 to the side edge 2220, the current transmission capacity between the first power terminal 21 and the second power terminal 22 is further enhanced.
[0084] In other embodiments, the length of the second straight portion 2121 can be equal to the length of the first straight portion 2120, but it is necessary to ensure that the free end of the second straight portion 2121 is connected to the side 2220 of the recess 222, thereby improving the docking strength of the folded straight beam 212. It should also be noted that for docking security considerations, the length of the second straight portion 2121 should not be less than (and can be slightly less than) the length of the first straight portion 2120, to ensure that the second straight portion 2121 has a sufficiently long electrical contact interval or a sufficiently large contact area.
[0085] In this embodiment, the second power terminal 22 includes a plurality of second curved oblique beams 221 and a plurality of notches 222 (e.g., three second curved oblique beams 221 and two notches 222), which are alternately arranged and correspond to the plurality of first curved oblique beams 211 and the plurality of folded straight beams 212, respectively. The present invention does not limit the specific number of the second curved oblique beams 221 and the notches 222.
[0086] In addition, if Figure 6a and Figure 6b As shown, the second power terminal 22 also has a structure similar to that of the first power terminal 21. For example, the second power terminal 22 also includes a plurality of pins 223, a fixing structure, and the like.
[0087] Please refer to Figure 4 and Figure 5 As shown, when the first power terminal 21 and the second power terminal 22 are combined together, the first main body 210 and the second main body 220 are parallel and close together, the first curved oblique beam 211 and the second curved oblique beam 221 face each other to form the pair of clamping beams, and the folded straight beam 212 forms an inserted beam, and its second straight portion 2121 is located in the recess 222.
[0088] In this embodiment, the first power terminals 21 and the second power terminals 22 together constitute three pairs of clamping beams and two insertion beams, which are alternately arranged to transmit power together.
[0089] More specifically, the first docking side 2101, the first fixing side 2102, the first mounting side 2103 and the first tail end side 2104 of the first body 210 are respectively aligned with the second docking side 2201, the second fixing side 2202, the second mounting side 2203 and the second tail end side 2204 of the second body 220. The first expansion portion 2110, the first contact portion 2111 and the first guide portion 2112 of the first curved oblique beam 211 are respectively aligned with the second expansion portion 2210, the second contact portion 2211 and the second guide portion 2212 of the second curved oblique beam 221, and an insertion space 201 is formed between the first expansion portion 2110 and the second expansion portion 2210 (see FIG. 2 ). Figure 4 ) is used to accommodate the inserted docking terminal assembly 60. An elastic clamping opening 202 (see FIG. 202 ) is formed between the first contact portion 2111 and the second contact portion 2211. Figure 4 ), used to provide elastic clamping and electrical contact functions, for example, it can elastically clamp the docking terminal assembly 60 and form electrical contact with the docking terminal assembly 60. A guide opening 203 (see FIG. 203 ) is formed between the first guide portion 2112 and the second guide portion 2212. Figure 4 ), used to provide a guiding function, for example, to guide the docking terminal assembly 60 into the elastic clamping opening 202. The width of the guide opening 203 is greater than the width of the elastic clamping opening 202.
[0090] The following will introduce Figure 7a 、 Figure 7b 、 Figure 7c 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.
[0091] Please refer to Figure 7a The illustrated first power terminal 21a has a folded straight beam 212a formed by a folding process to form a first straight portion 2120a, a second straight portion 2121a, and a folded portion 2123a. The first straight portion 2120a and the second straight portion 2121a are not completely parallel; an angle A exists between them. Furthermore, the second straight portion 2121a is provided with a power connection segment 2124, located at or near the free end of the second straight portion 2121a. The thickness of the power connection segment 2124 is thinner than that of other areas of the second straight portion 2121a. More specifically, the side of the first body 210a facing the first power terminal 21a at or near the free end of the second straight portion 2121a is thinned to form the power connection segment 2124. Therefore, the power connection segment 2124 can be referred to as a thinned segment.
[0092] Please refer to Figure 7a The second power terminal 22a shown has at least one power connection piece 2224 disposed in the recess 222a. The power connection piece 2224 protrudes forward from the side edge 2220a of the recess 222a in a direction generally perpendicular to the second mating side 2201a. In practice, the power connection piece 2224 is slightly inclined relative to the second body 220a and tilted toward the first power terminal 21a to facilitate a reliable connection with the power connection section 2124. The thickness of the power connection piece 2224 is less than the thickness of the second body 220a of the second power terminal 22a. Therefore, the power connection piece 2224 can be referred to as a thinning piece. In this embodiment, the power connection piece 2224 and the second body 220a are integrally formed.
[0093] Please refer to Figure 7b As shown, when the first power terminal 21 a and the second power terminal 22 a are combined together, the power connection section 2124 faces the power connection piece 2224 .
[0094] Please refer to Figure 7c As shown, when the power terminal assembly 20a is docked with the docking terminal assembly (not shown), the folded straight beam 212a is subjected to a clamping force, and the power connection section 2124 moves along with the second straight portion 2121a toward the power connection section 2124 and ultimately connects to the power connection piece 2224. That is, the power connection section 2124 abuts against the power connection piece 2224. In this way, the second straight portion 2121a is directly connected to the second power terminal 22a, thereby improving power transmission efficiency. Furthermore, because both the power connection section 2124 and the power connection piece 2224 are designed to be thinner, not only can the mating stability or fit of the power connection section 2124 and the power connection piece 2224 be improved, the thickness of the combined first power terminal 21a and the second power terminal 22a will not be affected.

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 beam (i.e., the first curved oblique beam 211 and the second curved oblique beam 221) and the insertion beam (i.e., the folded straight beam 212) 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 410 of the signal terminal 41 all enter the docking port 100; the pins 213, 223 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.
[0100] It should be noted that the first power terminal 21 and the second power terminal 22 can be 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, or a mutually clamping structure can be added to the first power terminal 21 and the second power terminal 22 to further provide a stable structure.
[0101] 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 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.
[0102] The structure and advantages of the docking connector 2 and the connector assembly 3 of the present invention will be described in detail below.
[0103] Please refer to Figure 8 、 Figure 9 、 Figure 10As 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. The docking terminal assembly 60 includes a third power terminal 61 and a fourth power terminal 62 combined together to transmit power together.

Figure 13 The third body 610 and the fourth body 620 are parallel to each other and abut against each other. The third curved oblique beam 611 and the fourth curved oblique beam 621 are arranged opposite each other to form a pair of clamping beams, while the folded straight beam 612 forms an insertion beam. The folded straight beam 612 corresponds to the recess 622, and a portion of the folded straight beam 612 is accommodated in the recess 622 and connected to the side 6220 of the recess 622.
[0105] From the above description, it can be seen that the structure of the docking terminal assembly 60 is roughly the same as that of the power terminal assembly 20. For example, the folded straight beam 612 of the docking terminal assembly 60 is similar to the folded straight beam 212 of the power terminal assembly 20, and the third curved oblique beam 611 and the fourth curved oblique beam 621 of the docking terminal assembly 60 are respectively similar to the first curved oblique beam 211 and the second curved oblique beam 221 of the power terminal assembly 20.
[0106] The main difference between the docking terminal assembly 60 and the power terminal assembly 20 lies in the different positions and numbers of the pair of clamping beams and the insertion beams. This is to ensure that the two can be properly plugged together during docking. For example, in this embodiment, the power terminal assembly 20 has three pairs of clamping beams and two insertion beams, while the docking terminal assembly 60 has three insertion beams and two pairs of clamping beams.
[0107] 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.
[0108] Please refer to Figure 14 and Figure 15In the connector combination shown, when the power connector 1 and the docking connector 2 are docked, the insertion beam of the power terminal assembly 20 (i.e., the folded straight beam 212) is inserted into a pair of clamping beams (i.e., the third curved oblique beam 611 and the fourth curved oblique beam 621) of the docking terminal assembly 60 and forms electrical conduction, while the insertion beam of the docking terminal assembly 60 (i.e., the folded straight beam 612) is inserted into a pair of clamping beams (i.e., the first curved oblique beam 211 and the second curved oblique beam 221) of the power terminal assembly 20 and forms electrical conduction, so as to transmit power together.
[0109] Please refer again Figure 10 As shown, in this embodiment, the docking connector 2 of the present invention includes a plurality of the docking terminal assemblies 60 , for example, four docking terminal assemblies 60 arranged side by side.
[0110] 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 10 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.
[0111] 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.
[0112] In addition, 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.
[0113] When the power connector 1 and the docking connector 2 are docked, Figure 15As shown, the insertion section 500 of the docking base 50 enters the docking port 100 of the insulating base 10, and the clamping beam and insertion beam of the first-type power terminal assembly 20 respectively dock with the insertion beam and clamping beam 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) 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.
[0114] Please refer to Figure 10 As 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.
[0115] In summary, the power connector 1 and connector assembly 3 of the present invention avoid the risk of unsafe docking by designing both the power terminal assembly 20 and the docking terminal assembly 60 with folded straight beams 212 and 612 serving as insertion beams. The connector assembly 3 of the present invention has a stable structure, provides safe docking, provides stable current conduction, and improves service life.
