Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a power connector and a signal triggering mechanism. Background Technology

[0002] Power connectors are used to supply power to electrical equipment. For example, this power connector is installed in a server rack and connected to a busbar to supply power to the server rack.

[0003] Currently, hot-plugging is required between the power connector and the busbar, which could potentially cause arcing and damage to components. To reduce arcing, some power connectors include a detection terminal that makes electrical contact with the busbar to ensure it is inserted into the power connector before power is applied.

[0004] However, it is still necessary to provide a safer and more reliable power connector to improve the safety of the entire electrical equipment. Utility Model Content

[0005] One objective of this invention is to provide a power connector that is equipped with active switching terminals and passive switching terminals, which can improve the safety of the power connector.

The passive switch terminal has a passive contact strip located on the side of the active contact portion facing away from the slot; the passive contact strip forms electrical contact with the active trigger terminal after the active contact portion is pressed by the insert, causing the active trigger terminal to displace, and disconnects electrical contact with the active trigger terminal after the insert is removed from the slot and the active contact portion is released.

[0014] In one embodiment, each signal trigger mechanism receiving slot is connected to the corresponding power transmission component receiving slot via a connecting slot, so that the switch fixing part of the active switch terminal can pass through.

[0015] In one embodiment, each power terminal is Z-shaped by two vertical bends and has a power contact portion, a power body portion, and a power cable connection portion arranged sequentially toward the slot; in the pair of power terminals, the power contact portions are used to jointly clamp the insert, and the distance between the power cable connection portions is less than the distance between the power body portions and less than or equal to the distance between the power contact portions.

[0016] In one embodiment, each conductive plate is Z-shaped by two vertical bends and has a reinforcing portion, a conductive body portion, and a conductive fixing portion arranged sequentially; wherein the conductive body portion is attached to the power supply body portion; the conductive fixing portion is attached to the power cable connection portion; the reinforcing portion extends toward the power contact portion; wherein the switch fixing portion of the active switch terminal is connected to the conductive body portion of the corresponding conductive plate.

[0017] In one embodiment, the active switch terminal and the conductive plate are a one-piece structure or a two-piece structure; the switch fixing part of the active switch terminal is an L-shaped plate, one end of which is connected to the conductive body part and the other end of which is connected to the active contact part; the active contact part is located on the side of the power contact part and behind the power contact part.

[0018] In one embodiment, the switch fixing part, the active contact part, and the active trigger end of the active switch terminal are all located on the side of the passive switch terminal closer to the slot; the passive contact strip of the passive switch terminal is straight, and the free end of the passive contact strip and the active trigger end are both oriented in the same direction.

[0019] In one embodiment, the active contact portion and the active trigger end are located on the side of the passive switch terminal closer to the slot; while the switch fixing portion is located on the side of the passive switch terminal opposite to the slot; wherein the switch fixing portion is connected to the active contact portion after being bent 180 degrees around the front end of the passive contact strip; the active trigger end is the free end of the active contact portion; wherein the free end of the passive contact strip faces the opposite direction to the active trigger end.

[0020] In one embodiment, the power transmission assembly includes at least a pair of power terminals; the pair of power terminals are distributed on both sides of the slot for electrical contact with two opposing insertion surfaces of the insert; wherein the switch fixing portion of the active switch terminal is connected to one of the power terminals; wherein the active trigger end of the active switch terminal is closer to the passive contact strip of the passive switch terminal than the active contact portion.

[0021] In one embodiment, each power terminal has a power contact portion, a power body portion, and a power cable connection portion that are sequentially arranged protruding toward the slot; the switch fixing portion of the active switch terminal is connected to the power body portion of the corresponding power terminal.

[0022] In one embodiment, both the active switch terminal and the passive switch terminal are independent of the power transmission component; the active switch terminal is directly fixed to the insulating housing via the switch fixing part; the active switch terminal and the passive switch terminal are arranged along the thickness direction of the slot and form a switch interval.

[0023] To achieve the above objectives, this utility model adopts the following technical solution: a signal triggering mechanism for forming electrical contact with an insert and triggering a signal, comprising an independent active switch terminal and a passive switch terminal, wherein the passive switch terminal and the active switch terminal form at least one switching interval. The active switch terminal has a switch fixing portion, an active contact portion, and an active triggering end arranged sequentially; wherein the active contact portion is used to make electrical contact with the insert, and the active triggering end is forced to displace after the active contact portion makes electrical contact with the insert. The passive switch terminal has a passive contact strip and a signal cable connection portion; wherein the passive contact strip is located on a displacement path of the active triggering end; the passive contact strip forms electrical contact with the active triggering end after the active contact portion makes electrical contact with the insert, and disconnects from the active triggering end after the insert releases the active contact portion; the signal cable connection portion is used to connect to at least one signal cable.

[0024] In one embodiment, the switching interval is the distance between the active trigger terminal and the passive contact strip; the passive contact strip is straight, and the free end of the passive contact strip and the active trigger terminal are oriented in the same direction or opposite directions.

[0025] Compared to existing technologies, the signal triggering mechanism of this invention, by setting up an active switch terminal and a passive switch terminal, and positioning the passive switch terminal on the path where the active switch terminal is displaced due to pressure from the insert, ensures that the active switch terminal can contact the passive switch terminal when pressed down by the insert, thereby stably and accurately triggering the power supply signal. The power connector of this invention, by setting up the signal triggering mechanism, allows the insert to sequentially form electrical contact with the power transmission component and the signal triggering mechanism. Therefore, the power transmission component is already in electrical contact with the insert before power is supplied, thus avoiding the generation of electric arcs. Furthermore, since the passive switch terminal and the active switch terminal are independently configured, if the insert is frequently inserted into the slot, the active switch terminal will be frequently pressured without affecting the structural stability of the passive switch terminal. For example, it will not cause the passive switch terminal to loosen in the receiving slot of the signal triggering mechanism, nor will it cause the connection between the signal cable fixing part and the signal cable to loosen. When the active switching terminal is pressed, its active trigger end moves toward the passive switching terminal. The passive switching terminal provides support or lift to the active trigger end of the active switching terminal to prevent excessive deformation of the active switching terminal. Therefore, the power supply signal of the power connector of this invention can be triggered stably and accurately, providing good safety. Attached Figure Description

[0077] The following description of the embodiments is with reference to the accompanying drawings, illustrating specific embodiments in which the present invention can be implemented. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and understanding of the present invention, and not for limiting the present invention.

[0078] The power connector of this invention can be installed in a server rack. When an insert, such as a busbar, is inserted into the power connector, power can be supplied to the server rack.

[0079] Please refer to Figures 1 to 10 As shown, in the first embodiment of this utility model, the power connector 1 includes an insulating housing 10, a power transmission component 20 disposed in the insulating housing 10, and at least one signal triggering mechanism 30 disposed in the insulating housing 10.

[0080] Please refer to Figure 1 and Figure 2 As shown, the insulating housing 10 has a slot 11 for inserting an insert 7, and the insert 7 can sequentially form electrical contact with the power transmission assembly 20 and the signal triggering mechanism 30. For example, the insert 7 can be a busbar. Please refer to... Figure 9 and Figure 10As shown, the signal triggering mechanism 30 includes an independent active switch terminal 31 and a passive switch terminal 32. The active switch terminal 31 has a switch fixing part 310, an active contact part 311, and an active trigger end 312 arranged sequentially. The active contact part 311 protrudes towards the slot 11 to make electrical contact with the insert 7. The active contact part 311 makes electrical contact with the insert 7 only after the power transmission assembly 20 makes electrical contact with the insert 7, and is pressed by the insert 7 to drive the active trigger end 312 to move away from the slot 11. The passive switch terminal 32 has a passive contact strip 320; wherein the passive contact strip 320 is located on the side of the active contact portion 311 facing away from the slot 11, and the passive contact strip 320 forms electrical contact with the active trigger end 312 after the active contact portion 311 is pressed by the insert 7, causing the active trigger end 312 to be displaced, and disconnects from the active trigger end 312 after the insert 7 is removed from the slot 11 and the active contact portion 311 is released.

[0081] With the above configuration, when the active switch terminal 31 touches the passive switch terminal 32, the power supply system of the power connector 1 will receive a power supply signal, and only then will the power supply system supply power to the insert 7. Since the power transmission component 20 has already made electrical contact with the insert 7 before power supply, no arc will be generated between the power transmission component 20 and the insert 7 during power supply.

[0082] It should be noted that the "mutually independent active switch terminal 31 and passive switch terminal 32" mentioned in this article refers to the fact that the active switch terminal 31 and passive switch terminal 32 were not connected or in contact before the insertion member 7.

[0083] In the first embodiment, as Figure 1 and Figure 5 As shown, the signal triggering mechanism 30 and the power transmission component 20 are arranged along the width direction W of the slot 11, while the passive switching terminal 32 and the active switching terminal 31 are arranged along the thickness direction T of the slot 11 and form a switching interval D (see reference numerals). Figure 8 In this embodiment, the switching interval D refers to the distance between the passive contact strip 320 and the active trigger terminal 312. Furthermore, in this embodiment, the active switch terminal 31 is entirely located on the side of the passive switch terminal 32 closest to the slot 11.

[0084] In the first embodiment, the active switch terminal 31 is connected to the power transmission assembly 20. For example, the active switch terminal 31 is connected to the power transmission assembly 20 via the switch fixing part 310, thereby fixing the active switch terminal 31 in the insulating housing 10 by means of the power transmission assembly 20. The passive switch terminal 32 is independent of the power transmission assembly 20.

[0085] Specifically, please refer to Figure 7 , Figure 9 and Figure 10 As shown, the power transmission assembly 20 includes a pair of power terminals and a pair of conductive plates. The pair of power terminals includes a first power terminal 21 and a second power terminal 21', distributed on both sides of the slot 11, for electrical contact with the two opposing insertion surfaces 701, 702 of the insert 7. The pair of conductive plates includes a first conductive plate 22 and a second conductive plate 22', respectively abutting against the outer surface of the pair of power terminals opposite to or away from the slot 11. For example, the first conductive plate 22 abuts against the outer surface 210 of the first power terminal 21 opposite to or away from the slot 11; while the second conductive plate 22' abuts against the outer surface 210' of the second power terminal 21' opposite to or away from the slot 11. In this configuration, the switch fixing portion 310 of the active switch terminal 31 is connected to one of the conductive plates (e.g., the first conductive plate 22); the active trigger end 312 of the active switch terminal 31 is closer to the passive contact strip 320 of the passive switch terminal 32 than the active contact portion 311; the passive switch terminal 32 is independent of the active switch terminal 31, the first power terminal 21, and the first conductive plate 22. That is, the passive switch terminal 32 is independent of the active switch terminal 31, the first power terminal 21, and the first conductive plate 22 before the insert 7 is inserted.

[0086] In the first embodiment, the power connector 1 further includes another signal triggering mechanism 30', such as... Figures 5 to 9 As shown. The other signal triggering mechanism 30' includes an independent active switch terminal 31' and a passive switch terminal 32'.

[0087] If we refer to the signal triggering mechanism 30 as the first signal triggering mechanism, the active switch terminal 31 as the first active switch terminal, and the passive switch terminal 32 as the first passive switch terminal, then the other signal triggering mechanism 30' is referred to as the second signal triggering mechanism, its active switch terminal 31' is referred to as the second active switch terminal, and its passive switch terminal 32' is referred to as the second passive switch terminal.

[0088] Therefore, the second signal triggering mechanism has the same structure as the first signal triggering mechanism, only the layout is different. For example, the first signal triggering mechanism is arranged on the side of one of the conductive plates (e.g., the first conductive plate 22), and the active switch terminal 31 (i.e., the first active switch terminal) is connected to the one of the conductive plates. The second signal triggering mechanism is arranged on the side of another conductive plate (e.g., the second conductive plate 22') away from the first signal triggering mechanism, and its active switch terminal 31' (i.e., the second active switch terminal) is connected to the other conductive plate. Figure 9 As shown, the first signal triggering mechanism is located on the right side of one of the conductive plates (e.g., the first conductive plate 22), while the second signal triggering mechanism is located on the left side of the other conductive plate (e.g., the second conductive plate 22').

[0089] The structural details of the power connector 1 in the first embodiment of this utility model will be described in detail below.

[0090] Please refer to Figures 3 to 6 As shown, in addition to the slot 11, the insulating housing 10 is also provided with a pair of power transmission component receiving slots (e.g., lower row power transmission component receiving slot 12 and upper row power transmission component receiving slot 12'), which are located on both sides of the slot 11 (e.g., below and above the slot 11) to receive the power transmission component 20. The pair of conductive plates (i.e., the first conductive plate 22 and the second conductive plate 22') and the pair of power terminals (i.e., the first power terminal 21 and the second power terminal 21') are received in the pair of power transmission component receiving slots.

[0091] Please refer to Figures 3 to 6 As shown, the insulating housing 10 also includes at least one signal triggering mechanism receiving slot (e.g., which may be referred to as the first signal triggering mechanism receiving slot 13), located in one of the power transmission component receiving slots (e.g. Figure 5 The signal triggering mechanism 30 (i.e., the first signal triggering mechanism) is housed on the side of the lower power transmission component receiving slot 12 shown. The active switching terminal 31 is arranged adjacent to the slot 11, while the passive switching terminal 32 is arranged away from the slot 11. That is, in Figure 5 In the signal trigger mechanism receiving slot (i.e., the first signal trigger mechanism receiving slot 13) located below the slot 11, the active switch terminal 31 is arranged above the passive switch terminal 32.

[0092] More specifically, such as Figure 4 and Figure 5As shown, the insulating housing 10 includes a pair of signal trigger mechanism receiving slots (e.g., the first signal trigger mechanism receiving slot 13 and the second signal trigger mechanism receiving slot 13'), located on both sides of the slot 11 (e.g., below and above the slot 11), and arranged side by side with the corresponding power transmission component receiving slots (i.e., the lower row power transmission component receiving slot 12 and the upper row power transmission component receiving slot 12') along the width direction W of the slot 11, for example in... Figure 4 In the rear view of the insulating housing 10 shown, a signal triggering mechanism receiving slot (e.g., the first signal triggering mechanism receiving slot 13) is provided on the left side of the lower power transmission component receiving slot 12 to receive the first signal triggering mechanism (i.e., the signal triggering mechanism 30); while another signal triggering mechanism receiving slot (e.g., the second signal triggering mechanism receiving slot 13') is provided on the right side of the upper power transmission component receiving slot 12' to receive the second signal triggering mechanism (i.e., the other signal triggering mechanism 30'). The insulating housing 10 also includes at least one connecting slot 14 (see reference numerals). Figure 5 The connecting slot 14 is used to connect one of the signal trigger mechanism receiving slots (e.g., the first signal trigger mechanism receiving slot 13) with the corresponding power transmission component receiving slot (i.e., the lower power transmission component receiving slot 12). Specifically, the connecting slot 14 is used for the switch fixing part 310 of the active switch terminal 31 to pass through, so that the active trigger end 312 and the active contact part 311 of the active switch terminal 31 both enter one of the signal trigger mechanism receiving slots. In one of the signal trigger mechanism receiving slots, the active contact part 311 of the active switch terminal 31 protrudes from the slot 11 towards the slot, while the active trigger end 312 is located in the slot, ready to be displaced after the active contact part 311 is pressed down or pushed up, so as to make electrical contact with the passive switch terminal 32 located in the slot 13.

[0093] like Figure 4 As shown, the power transmission component receiving slot (i.e., the lower row power transmission component receiving slot 12) and one of the signal triggering mechanism receiving slots (i.e., the first signal triggering mechanism receiving slot 13) on one side of the slot 11 (e.g., below the slot 11) are arranged parallel to the power transmission component receiving slot (i.e., the upper row power transmission component receiving slot 12') and the other signal triggering mechanism receiving slot (i.e., the second signal triggering mechanism receiving slot 13') on the other side of the slot 11 (e.g., above the slot 11) by a 180-degree horizontal rotation, for example along... Figure 4 The items are arranged in parallel by rotating horizontally by 180 degrees in the left and right directions, as shown.

[0094] In addition, such as Figure 2 As shown, the insulating housing 10 further includes a flange 101, an insulating front portion 102 located in front of the flange 101, and an insulating rear portion 103 located behind the flange 101. The slot 11 is disposed in the insulating front portion 102. The power transmission component receiving slot (e.g., the lower row power transmission component receiving slot 12) and the signal triggering mechanism receiving slot (e.g., the first signal triggering mechanism receiving slot 13) extend from the insulating front portion 102 and pass through the insulating rear portion 103. Figure 5 As shown, the power connector 1 includes a pair of grounding terminals 40 fixed to the flange 101, and each grounding terminal 40 is provided with a plurality of first elastic fingers 41 extending along the insulating front portion 102 and a plurality of second elastic fingers 42 extending along the flange 101 and perpendicular to the first elastic fingers 41.

[0095] Please refer to Figure 9 and Figure 10 As shown, each power terminal, such as the first power terminal 21, is generally Z-shaped after two vertical bends, and has a power contact portion 211, a power body portion 212, and a power cable connection portion 213 arranged sequentially towards the slot 11. More specifically, the power contact portion 211 is bent into a generally V-shape, protruding into the slot 11 to form electrical contact with the insert 7. The power cable connection portion 213 is a flat plate used to fixally connect to at least one power cable 23. In this embodiment, the power cable connection portion 213 is fixedly connected to the power cable 23 through the first conductive plate 22. Furthermore, the power cable connection portion 213 is fixedly connected to the power cable 23 through the first conductive plate 22 and a soldering plate 24.

[0096] In this embodiment, as Figure 2 , Figure 8 and Figure 9 As shown, the pair of power terminals are housed in corresponding power transmission component receiving slots (e.g., the lower row power transmission component receiving slot 12 and the upper row power transmission component receiving slot 12'), wherein reference numerals 12 and 12' are shown in the figure. Figure 6In the pair of power terminals, the power contact portion 211 of the first power terminal 21 and the power contact portion 211' of the second power terminal 21' are used to jointly clamp and electrically contact the insert 7. The power body portion 212 of the first power terminal 21 and the power body portion 212' of the second power terminal 21' are far apart from each other, and after two vertical bends, the power cable connection portion 213 of the first power terminal 21 and the power cable connection portion 213' of the second power terminal 21' are brought closer together. Therefore, the distance D1 between the power cable connection portions 213 and 213' is approximately smaller than the distance D2 between the power body portions 212 and 212', and smaller than or equal to the distance D3 between the power contact portions 211 and 211'.

[0097] In addition, such as Figure 10 As shown, each power terminal, such as the first power terminal 21, also has a power head 214 located at the front end of the power contact portion 211 and capable of being embedded in the front end of the power transmission component receiving groove (such as the lower row power transmission component receiving groove 12) to prevent it from tilting up.

[0098] Please refer to Figure 9 and Figure 10 As shown, the pair of conductive plates abut against the outer surface of the corresponding power terminal away from the slot 11, and together with the corresponding power terminal, are housed in the corresponding power transmission component receiving slot. Specifically, please refer to... Figure 10 As shown, each conductive plate, such as the first conductive plate 22, is approximately Z-shaped after two vertical bends and has a reinforcing portion 220, a conductive body portion 221, and a conductive fixing portion 222 arranged sequentially. The conductive body portion 221 abuts against the power body portion 212; the conductive fixing portion 222 is a flat plate that abuts against the power cable connection portion 213. The reinforcing portion 220 is slightly bent relative to the conductive body portion 221, thus slightly inclined to the conductive body portion 221, and extends toward the power contact portion 211 of the first power terminal 21 to improve the strength of the power contact portion 211. The length of the reinforcing portion 220 can be determined according to the material of the first power terminal 21 and the first conductive plate 22, or according to the required mechanical or electrical performance. In summary, the first conductive plate 22 abuts against at least a portion of the structure of the first power terminal 21, which can improve the reliability of the electrical contact between the first power terminal 21 and the insert 7 and the safety of the mechanical connection.

[0099] In the first embodiment, as Figure 9 and Figure 10As shown, the active switch terminal 31 is connected to the first conductive plate 22 and arranged side-by-side with it. Specifically, the switch fixing part 310 of the active switch terminal 31 is connected to the conductive body part 221 of the first conductive plate 22. For example, the active switch terminal 31 and the first conductive plate 22 are manufactured into a one-piece or integral structure by a stamping process, in which case the switch fixing part 310 extends vertically from the side edge of the conductive body part 221. Of course, the active switch terminal 31 and the first conductive plate 22 can also be manufactured separately as a two-piece or split structure, and the active switch terminal 31 can be connected to the conductive body part 221 by welding or other methods.

[0100] like Figure 10 As shown, the switch fixing part 310 of the active switch terminal 31 is an L-shaped plate, one end of which is connected to the conductive body part 221, and the other end of which is connected to the active contact part 311. The active contact part 311 is bent into a roughly V-shape, protruding into the slot 11 to form electrical contact with the insert 7. When the first conductive plate 22 is against the outer surface of the first power terminal 21, as... Figure 9 As shown, the active contact portion 311 is located on the side (e.g., right or left) of the power contact portion 211. The active contact portion 311 and the power contact portion 211 are approximately the same height. The active contact portion 311 and the power contact portion 211 are staggered, for example, the active contact portion 311 is located behind the power contact portion 211. With this design, the active contact portion 311 can make electrical contact with the insert 7 only after the first power terminal 21 has made electrical contact with the insert 7. In this embodiment, the active trigger end 312 is the free end (e.g., the front end) of the active contact portion 311. The active trigger end 312 extends toward the front end of the first signal trigger mechanism receiving groove 13 and is embedded in the first signal trigger mechanism receiving groove 13. This not only prevents the active switch terminal 31 from tilting up, but also allows the active contact portion 311 to shift toward the passive switch terminal 32 after being pressed by the insert 7, thereby forming a reliable electrical contact.

[0101] like Figure 8 As shown, the active switch terminal 31 and the passive switch terminal 32 are along the thickness direction T (see reference numerals) of the slot 11. Figure 5The switch interval D is arranged and formed, with the active switch terminal 31 located on the side of the passive switch terminal 32 closer to the slot 11. It can be seen that the passive switch terminal 32 is positioned on the path of displacement of the active switch terminal 31 due to pressure from the insert 7. Specifically, the passive switch terminal 32 is independent of the active switch terminal 31, the first power terminal 21, and the first conductive plate 22, and is housed together with the active switch terminal 31 in the first signal trigger mechanism receiving slot 13, with the two arranged approximately vertically. For example, for the first signal trigger mechanism, the passive switch terminal 32 is located below the active switch terminal 31; for the second signal trigger mechanism, the passive switch terminal 32' is located above the active switch terminal 31'.

[0102] In this embodiment, the active trigger end 312 is closer to the passive contact strip 320 of the passive switch terminal 32 than the active contact portion 311, and the active trigger end 312 extends toward the front end of the signal trigger mechanism receiving groove 13.

[0103] More specifically, in the first embodiment, as Figure 8 and Figure 10 As shown, the passive contact strip 320 of the passive switch terminal 32 is straight. The free end 322 of the passive contact strip 320 and the active trigger end 312 both face the same direction, for example, towards the front end of the first signal trigger mechanism receiving groove 13. The free end 322 of the passive contact strip 320 is approximately aligned with the corresponding active trigger end 312, or may extend beyond the active trigger end 312. That is, the length of the passive contact strip 320 ensures that the active trigger end 312 and the passive contact strip 320 form electrical contact after the insert 7 is inserted, and even allows the active trigger end 312 to slide on the passive contact strip 320. Furthermore, as Figure 10 As shown, the passive switch terminal 32 also includes a signal cable connection part 321, which is horizontally and linearly connected to the passive contact strip 320, and is used to fix it to a signal cable 33.

[0104] However, this utility model does not limit the vertical position of the passive switching terminal 32 and the active switching terminal 31. As long as the passive contact strip 320 of the passive switching terminal 32 is positioned on the displacement path of the active triggering end 312 of the active switching terminal 31, electrical contact between the passive switching terminal 32 and the active switching terminal 31 can be achieved. For example, please refer to... Figure 11 Another embodiment of the signal triggering mechanism 30a of this utility model, referred to as the first signal triggering mechanism, is shown.

[0105] exist Figure 11 The elements or structures in the illustrated embodiments are the same as those described above. Figures 1 to 10 Similar elements or structures in the first embodiment shown share the same markings and are additionally marked with the suffix "a".

[0106] exist Figure 11 In the illustrated embodiment, the active switch terminal 31a partially surrounds the passive switch terminal 32a. A portion of the structure of the active switch terminal 31a (e.g., the active contact portion 311a and the active trigger terminal 312a) may be located on the side of the passive switch terminal 32a closer to the slot 11a, while another portion of the structure of the active switch terminal 31a (e.g., the switch fixing portion 310a) may be located on the side of the passive switch terminal 32a away from the slot 11a. That is, the passive contact strip 320a of the passive switch terminal 32a is closer to the slot 11a than the switch fixing portion 310a of the active switch terminal 31a.

[0107] Specifically, in Figure 11 In the illustrated embodiment, for the first signal triggering mechanism, the passive contact strip 320a is located above the switch fixing portion 310a. The switch fixing portion 310a is bent approximately 180 degrees around the front end of the passive contact strip 320a and then connected to the active contact portion 311a. The active triggering end 312a is the free end (e.g., the rear end) of the active contact portion 311a and extends toward the rear end of the signal triggering mechanism receiving groove 13a. At this time, the active contact portion 311a is located above the passive contact strip 320a and protrudes into the slot 11a; the active triggering end 312a is also located above the passive contact strip 320a, and the active triggering end 312a and the free end 322a of the passive contact strip 320a face opposite directions. This design ensures that the active switch terminal 31a and the insert 7 (see reference numerals) are connected. Figure 2 Secure docking.

[0108] Similarly, the second signal triggering mechanism of this utility model (i.e., the other signal triggering mechanism 30') can also be adopted as follows: Figure 11 The structure shown is not described in detail here.

[0109] Please refer to Figures 12 to 15 As shown, it illustrates the power connector 1b of a second embodiment of the present invention. The components or structures in this second embodiment are similar to... Figures 1 to 10 Similar elements or structures in the first embodiment shown share the same markings and are additionally marked with the suffix 'b'.

[0110] The power connector 1b of this second embodiment has a structure that is substantially the same as that of the power connector 1 of the first embodiment described above. For example, in this second embodiment, as... Figures 12 to 15 As shown, the power connector 1b includes: an insulating housing 10b, a power transmission component 20b disposed in the insulating housing 10b, and at least one signal triggering mechanism 30b disposed in the insulating housing 10b. The signal triggering mechanism 30b includes an independent active switching terminal 31b and a passive switching terminal 32b. The power transmission component 20b includes at least a pair of power terminals, the pair of power terminals including a first power terminal 21b and a second power terminal 21b'. In the second embodiment, as... Figure 15 As shown, each power terminal, such as the first power terminal 21b, has a power contact portion 211b protruding toward the slot 11b, a power body portion 212b, and a power cable connection portion 213b arranged sequentially.

[0111] The other similarities between this second embodiment and the first embodiment described above will not be repeated here.

[0112] The main difference between the power connector 1b of this second embodiment and the power connector 1 of the first embodiment is that, in this second embodiment, the switch fixing part 310b of the active switch terminal 31b is connected to one of the power terminals of the power transmission assembly 20b (e.g., the first power terminal 21b). Specifically, the switch fixing part 310b is connected to the power body part 212b. By connecting the active switch terminal 31b to the first power terminal 21b, the active switch terminal 31b is positioned in the signal trigger mechanism receiving slot (e.g., the first signal trigger mechanism receiving slot 13b), thereby fixing the active switch terminal 31b.

[0113] In this second embodiment, the active switch terminal 31b and the first power supply terminal 21b are manufactured into a one-piece or integrated structure by stamping. Alternatively, the active switch terminal 31b and the first power supply terminal 21b can be manufactured separately as a two-piece or split structure. In this case, the active switch terminal 31b can be connected to the power supply body 212b by welding or other methods.

[0114] Furthermore, in this second embodiment, the conductive plate is not a necessary component. Of course, depending on the actual structural strength of the power connector 1b, a pair of conductive plates (including a first conductive plate 22b and a second conductive plate 22b') can be provided to provide structural reinforcement for the pair of power terminals.

[0115] It should also be noted that the power connector 1b further includes another signal triggering mechanism 30b'. If the signal triggering mechanism 30b is referred to as the first signal triggering mechanism, then the other signal triggering mechanism 30b' is referred to as the second signal triggering mechanism. The first signal triggering mechanism and the second signal triggering mechanism can also adopt the following... Figure 11 The structure shown.

[0116] Please refer to Figures 16 to 18 As shown, it illustrates a power connector 1c according to a third embodiment of the present invention. The components or structures in this third embodiment are similar to... Figures 1 to 10 Similar elements or structures in the first embodiment shown share the same markings and are additionally marked with the suffix "c".

[0117] The power connector 1c of this third embodiment has a structure that is substantially the same as that of the power connector 1 of the first embodiment. For example, in this third embodiment, the power connector 1c includes: an insulating housing 10c, a power transmission assembly 20c disposed in the insulating housing 10c and located on both sides of the slot 11c, and at least one signal triggering mechanism 30c disposed in the insulating housing 10c. The signal triggering mechanism 30c includes an independent active switching terminal 31c and a passive switching terminal 32c.

[0118] The other similarities between this third embodiment and the first embodiment described above will not be repeated here.

[0119] The main difference between the power connector 1c of this third embodiment and the power connector 1 of the first embodiment is that, in this third embodiment, the active switch terminal 31c is not connected to the power transmission component 20c, and both the active switch terminal 31c and the passive switch terminal 32c are independent of the power transmission component 20c; wherein the active switch terminal 31c is directly fixed to the insulating housing 10c by the switch fixing part 310c. Specifically, the switch fixing part 310c can be directly embedded in the insulating housing 10c by injection molding, thereby fixing the active switch terminal 31c in the signal triggering mechanism receiving groove 13c of the insulating housing 10c. Of course, in other embodiments, a locking structure can also be provided on the switch fixing part 310c to install and fix the active switch terminal 31c in the signal triggering mechanism receiving groove 13c of the insulating housing 10c.

[0120] The power connector 1c also includes another signal triggering mechanism 30c'. If the signal triggering mechanism 30c is referred to as the first signal triggering mechanism, then the other signal triggering mechanism 30c' is referred to as the second signal triggering mechanism. The first signal triggering mechanism and the second signal triggering mechanism can also adopt the following... Figure 11 The structure shown.

[0121] It is evident from the above three embodiments that the power connector of this invention achieves fixation of the active switch terminal by connecting the active switch terminal to the power transmission component (e.g., to the first conductive plate or the first power terminal); the power connector of this invention can also fix the active switch terminal by independently placing it in the insulating housing. Before the insert is inserted into the slot, the active switch terminal and the passive switch terminal are independent of each other and form the switching interval; after the insert is inserted into the slot and the insert presses against the active switch terminal, the active switch terminal and the passive switch terminal form electrical contact.

[0122] In summary, the power connector of this utility model, such as the power connector 1, by setting the active switch terminal 31 and the passive switch terminal 32, and placing the passive switch terminal 32 on the path where the active switch terminal 31 is displaced due to pressure from the insert 7, ensures that when the active switch terminal 31 is pressed down by the insert 7, it can touch the passive switch terminal 32 to trigger a power supply signal. Furthermore, since the passive switch terminal 32 and the active switch terminal 31 are independently configured, if the insert 7 is frequently inserted into the slot 11, the active switch terminal 31 will be frequently pressured. The active switch terminal 31 will not affect the structural stability of the passive switch terminal 32; for example, it will not cause the passive switch terminal 32 to loosen in the signal trigger mechanism receiving slot 13, nor will it cause the connection between the signal cable connection part 321 and the signal cable 33 to loosen. When the active switch terminal 31 is pressed, its active trigger end 312 moves toward the passive switch terminal 32. The passive switch terminal 32 can support the active trigger end 312 of the active switch terminal 31 to prevent the active switch terminal 31 from being excessively deformed. Therefore, the power supply signal of the power connector 1 of this utility model can be triggered stably and accurately, and has good safety.
