[0038] Please see Figure 1 and Figure 2 The first embodiment of this utility model provides a connector 100, which includes a connector core 20, a power terminal 40, a signal terminal 50, a waterproof colloid 60, and a sealing gasket 80. The connector core 20 includes a first connecting portion 22 and a second connecting portion 24 located at opposite ends. The connector core 20 is provided with a first positioning hole 25 and a second positioning hole 26 passing through the first connecting portion 22 and the second connecting portion 24. The power terminal 40 can be positioned in the first positioning hole 25. The power terminal 40 includes a first conductive portion 42 and a second conductive portion 44 located at opposite ends. Part 44 exposes the opposite ends of the first positioning hole 25. The first conductive part 42 is used to abut against the power contact plate on the circuit board, and the second conductive part 44 is inserted into the external power docking terminal. The signal terminal 50 is positioned in the second positioning hole 26. The signal terminal 50 includes a first signal connection section 52 and a second signal connection section 54 located at opposite ends. The first signal connection section 52 and the second signal connection section 54 expose the opposite ends of the second positioning hole 26. The first signal connection section 52 is used to abut against the signal contact plate on the circuit board, and the second signal connection section 54 is inserted into the external signal docking terminal.

[0039] Optionally, the connector 100 can be used for, but is not limited to, batteries. Specifically, the connector 100 is directly connected to the battery casing, such that the first conductive portion 42 of the power terminal 40 abuts against the power contact pad of the battery circuit board, and the first signal connection portion 52 of the signal terminal 50 abuts against the signal contact pad of the battery circuit board; the second connection portion 24 of the connector 100 protrudes from the battery casing to facilitate the insertion of an external plug.

[0040] In this embodiment, the connector core 20 is provided with two first positioning holes 25 and six second positioning holes 26 spaced apart from each other. One end of each first positioning hole 25 passes through the end face of the first connecting portion 22 away from the second connecting portion 24, and the other end of the first positioning hole 25 passes through the end face of the second connecting portion 24 away from the first connecting portion 22. One end of each second positioning hole 26 passes through the end face of the first connecting portion 22 away from the second connecting portion 24, and the other end of the second positioning hole 26 passes through the end face of the second connecting portion 24 away from the first connecting portion 22. The two first positioning holes 25 are located in the middle of the first connecting portion 22, one of the second positioning holes 26 is located on one side of the two first positioning holes 25, and the other five second positioning holes 26 are located on the opposite side of the two first positioning holes 25. There are two power terminals 40, one of which is the positive terminal and the other is the negative terminal. The two power terminals 40 are respectively positioned in two first positioning holes 25. There are six signal terminals 50, which are respectively positioned in six second positioning holes 26.

[0041] When the connector 100 of this application is connected to an electronic product such as a battery, the first conductive portion 42 of the power terminal 40 of the connector 100 directly abuts against the power contact pad on the circuit board inside the electronic product, and the first signal connection portion 52 of the signal terminal 50 directly abuts against the signal contact pad on the circuit board. Therefore, the connector 100 saves the wires between itself and the circuit board, which not only avoids the wires occupying the internal space of the electronic product, but also helps to miniaturize the electronic product and reduces manufacturing costs.

[0042] like Figures 2-4 As shown, the connector core 20 also includes a positioning portion 27 connected between the first connecting portion 22 and the second connecting portion 24. The positioning portion 27 is used to fix the connector 100 to the electronic product. The first connecting portion 22 protrudes from one side of the positioning portion 27, and the second connecting portion 24 protrudes from the opposite side of the positioning portion 27. In this embodiment, the positioning portion 27 is a rectangular plate, and both the first connecting portion 22 and the second connecting portion 24 are cylinders. The axis of the first connecting portion 22 is collinear with the axis of the second connecting portion 24. The diameter of the first connecting portion 22 may be equal to or unequal to the diameter of the second connecting portion 24. Generally, the diameter of the first connecting portion 22 is close to the diameter of the second connecting portion 24; optionally, the diameter of the first connecting portion 22 is equal to the diameter of the second connecting portion 24. The positioning part 27 protrudes radially from the first connecting part 22 and the second connecting part 24 around its periphery. A first connecting hole 272 is provided at each of the four corners of the positioning part 27. The axes of the first positioning hole 25 and the second positioning hole 26 are parallel to the axis of the first connecting part 22. In other embodiments, the positioning part 27 may be, but is not limited to, a circular plate, an elliptical plate, or a polygonal plate.

[0043] Optionally, the first connecting portion 22 is provided with a first positioning step 252 on the inner peripheral surface of the first positioning hole 25. Specifically, the first positioning hole 25 includes a first positioning segment 251 and a second positioning segment 253 that are axially connected. The first positioning segment 251 is located on the first connecting portion 22 and passes through the first connecting portion 22. The end of the second positioning segment 253 facing away from the first positioning segment 251 passes through the positioning portion 27. The inner diameter of the first positioning segment 251 is larger than the inner diameter of the second positioning segment 253 to form the first positioning step 252. The first connecting portion 22 is provided with a second positioning step 262 on the inner peripheral surface of the second positioning hole 26. Specifically, the second positioning hole 26 includes a third positioning segment 261 and a fourth positioning segment 263 that are axially connected. The third positioning segment 261 is located on the first connecting portion 22 and passes through the first connecting portion 22. The end of the fourth positioning segment 263 facing away from the third positioning segment 261 passes through the positioning portion 27. The inner diameter of the third positioning segment 261 is larger than the inner diameter of the fourth positioning segment 263 to form the second positioning step 262. A waterproof cavity 223 is provided on the end face of the first connecting portion 22 facing away from the second connecting portion 24. The waterproof cavity 223 connects the first positioning hole 25 and the second positioning hole 26. In this embodiment, the waterproof cavity 223 is a circular cavity, and the axis of the circular cavity is collinear with the axis of the first connecting portion 22. In other embodiments, the waterproof cavity 223 may be, but is not limited to, a polygonal cavity, a rectangular cavity, or an elliptical cavity. Optionally, the outer peripheral surface of the first connecting portion 22 is provided with a foolproof surface 226, which is used to prevent the connector core 20 from being inserted backwards. The inner peripheral surface of the waterproof cavity 223 may be an inclined surface or a straight surface. That is, depending on the manufacturing process of the connector core 20, such as whether a draft angle is left or not during mold injection, or the inner peripheral surface of the waterproof cavity 223 produced by machining or other processes on the connector core 20 may also be inwardly inclined or straight. Preferably, the inner peripheral surface of the waterproof cavity 223 of the first connecting portion 22 is inclined relative to the axis of the first connecting portion 22. Specifically, the side of the inner peripheral surface closer to the second connecting portion 24 is further away from the axis of the first connecting portion 22 than the side farther away from the second connecting portion 24. That is, the inner diameter of the end of the inner peripheral surface closer to the second connecting portion 24 is larger than the inner diameter of the end farther away from the second connecting portion 24. The inner peripheral surface of the waterproof cavity 223 of the first connecting portion 22 is set to be inwardly inclined, which can prevent the glue layer filled in the waterproof cavity 223 from falling out.

[0044] Optionally, the second connecting portion 24 includes a connecting sleeve 242, a first positioning cylinder 244, and a second positioning cylinder 246 disposed around the end face of the positioning portion 27 opposite to the first connecting portion 22. Both the first positioning cylinder 244 and the second positioning cylinder 246 are located within the connecting sleeve 242. One end of the first positioning cylinder 244 is connected to the end face of the positioning portion 27 opposite to the first connecting portion 22 and surrounds the first positioning hole 25. One end of the second positioning cylinder 246 is connected to the end face of the positioning portion 27 opposite to the first connecting portion 22 and surrounds the second positioning hole 26. The axes of the connecting sleeve 242, the first positioning cylinder 244, and the second positioning cylinder 246 are parallel to each other. The inner diameter of the first positioning cylinder 244 is slightly smaller than or equal to the inner diameter of the second positioning segment 253, and the inner diameter of the second positioning cylinder 246 is slightly smaller than or equal to the inner diameter of the fourth positioning segment 263. The first opening 2441 of the first positioning cylinder 244 is smaller than the inner diameter of the first positioning cylinder 244 to form a first abutting step 2443; the second opening 2461 of the second positioning cylinder 246 is smaller than the inner diameter of the second positioning cylinder 246 to form a second abutting step 2463. Optionally, the outer peripheral surface of the second connecting part 24 is provided with a positioning groove 247, which is used to position the external connector.

[0045] like Figures 4-9 As shown, the power terminal 40 also includes a third connecting portion 45 connected to the first conductive portion 42 and the second conductive portion 44. A first connecting boss 452 is provided between the third connecting portion 45 and the second conductive portion 44, and the first connecting boss 452 can be positioned on the first positioning step 252. Specifically, the first conductive portion 42, the third connecting portion 45, and the second conductive portion 44 are arranged along the length direction of the power terminal 40. The third connecting portion 45 is cylindrical. The first conductive portion 42 is a connecting cylinder provided at one end of the third connecting portion 45, and the second conductive portion 44 is a conductive cylinder provided at the opposite end of the third connecting portion 45. The diameter of the first conductive portion 42 is larger than the diameter of the third connecting portion 45, thereby forming a positioning boss 422 between the first conductive portion 42 and the third connecting portion 45. The diameter of the third connecting portion 45 is larger than the diameter of the second conductive portion 44, thereby forming a first connecting boss 452 between the third connecting portion 45 and the second conductive portion 44. In this embodiment, the outer peripheral surface of the second conductive portion 44 is provided with at least one ring of barbs 442, which are used for positioning to the inner peripheral surface of the first positioning hole 25. In other embodiments, the outer peripheral surface of the third connecting portion 45 is provided with at least one ring of barbs, which are used for positioning to the inner peripheral surface of the first positioning segment 251 of the first positioning hole 25. In other embodiments, the outer peripheral surfaces of the second conductive portion 44 and the third connecting portion 45 are each provided with at least one ring of barbs, which are used for positioning to the inner peripheral surface of the first positioning hole 25.

[0046] Optionally, the second conductive portion 44 includes a plurality of conductive sheets 444 disposed at the end of the third connecting portion 45 opposite to the first conductive portion 42. The plurality of conductive sheets 444 are arranged in a circle around the circumference of the third connecting portion 45 to form a first insertion hole 445, which is used for the insertion of an external power supply conductive pin. In this embodiment, the conductive sheet 444 is an arc-shaped sheet, and the plurality of conductive sheets 444 are arranged in a circle at uniform intervals around the circumference of the third connecting portion 45.

[0047] like Figure 5 and Figures 8-9 As shown, the connector 100 also includes a conductive contact elastic element 70. The contact elastic element 70 is made of a highly conductive and highly elastic spring wire, which can be manufactured by twisting and bending a single spring wire using a spring machine, and then welding or bonding the ends of the spring wire together. The contact elastic element 70 is connected to the first conductive part 42 and is used to elastically abut against the power contact pad of the circuit board. Specifically, one end of the contact elastic element 70 is engaged with the connecting cylinder, and the opposite end of the contact elastic element 70 can elastically abut against the power contact pad. In this embodiment, the end face of the first conductive part 42 facing away from the second conductive part 44 is provided with a second connecting hole 424, and one end of the contact elastic element 70 is engaged with the second connecting hole 424. The finger elastic element 70 includes multiple elastic rings 72, which surround the circumference of the connecting cylinder. When the finger elastic element 70 is engaged in the second connecting hole 424 of the first conductive part 42, the axis of the finger elastic element 70 is collinear with the axis of the first conductive part 42 (i.e., the connecting cylinder), and the end of the finger elastic element 70 away from the second conductive part 44 extends out of the connecting cylinder. Figure 7 As shown, the included angle θ between the inner circumferential surface of the second connecting hole 424 of the first conductive part 42 and the bottom surface is less than 90 degrees. Specifically, the included angle θ is greater than 45 degrees and less than 90 degrees. In this embodiment, the included angle θ of the first conductive part 42 is 60 degrees.

[0048] Specifically, the elastic ring 72 includes a positioning rod 721, a stop rod 723, an outer connecting rod 725, and an inner connecting rod 727. The positioning rod 721 and the stop rod 723 are located at opposite ends of the elastic ring 72. The opposite ends of the outer connecting rod 725 are respectively connected to the outer ends of the positioning rod 721 and the stop rod 723. The opposite ends of the inner connecting rod 727 are respectively connected to the inner ends of the positioning rod 721 and the stop rod 723. The positioning rod 721 is used to abut against the bottom surface of the second connecting hole 424 of the first conductive part 42. The end of the outer connecting rod 725 near the positioning rod 721 abuts against the inner circumferential surface of the second connecting hole 424, and the inner connecting rod 727 is away from the inner circumferential surface of the second connecting hole 424. The stop rod 723 abuts against the power contact plate. The angle between the positioning rod 721 and the outer connecting rod 725 of the elastic ring 72 and the angle θ of the first conductive part 42 may be the same or different. When the mounting space of the finger elastic element 70 is small, the included angle θ of the first conductive part 42 can be larger; when the mounting space of the finger elastic element 70 is large, the included angle of the first conductive part 42 can be smaller.

[0049] Optionally, multiple positioning rods 721 form a positioning ring 722, which is positioned in the second connecting hole 424 of the first conductive part 42. The outer contour of the finger elastic member 70 is tapered. From the side view of the finger elastic member 70, the outer connecting rod 725 and the adjacent positioning rod 721 are inclined on the same side relative to the plane where the positioning ring 722 is located. The plane of the outer connecting rod 725 and the positioning rod 721 forms a certain angle A with the plane where the positioning ring 722 is located. Specifically, the first plane where the interconnected outer connecting rod 725 and the positioning rod 721 are located forms an angle A with the second plane where the positioning ring 722 is located. The angle A is greater than or equal to 60 degrees and less than or equal to 90 degrees. Specifically, the angle A can be, but is not limited to, 60 degrees, 65 degrees, 70 degrees, 72 degrees, 80 degrees or 85 degrees, etc. Preferably, the angle A is between 70 degrees and 85 degrees. Multiple abutment rods 723 form an abutment ring 724, with the abutment ring 724 exposing the first conductive part 42 (i.e., the connecting cylinder). The abutment ring 724 rotates relative to the positioning ring 722 by a certain rotation angle B, the value of which is between 30 and 50 degrees. Specifically, the positioning rod 721 and the abutment rods 723 of the same elastic ring 72 form a rotation angle B on the plane where the abutment ring 724 is located. The angle of rotation angle B is greater than 30 degrees and less than 50 degrees. That is, the angle of rotation angle B can be, but is not limited to, 30 degrees, 33 degrees, 35 degrees, 40 degrees, 45 degrees, or 50 degrees. In this embodiment, the included angle A of the contact finger elastic element 70 is 80 degrees, and the angle of rotation angle B of the contact finger elastic element 70 is 35 degrees.

[0050] When a force F is applied to the abutment ring 724, the abutment ring 724 of the contact finger elastic member 70 moves towards the positioning ring 722. At the same time, the included angle A becomes smaller and smaller, and the rotation angle B becomes larger and larger, until the spring force of the contact finger elastic member 70 along its axis is balanced with the applied force F. That is, if the initial state of the included angle A is 75 degrees and the rotation angle B is 80 degrees, during the contraction process of the contact finger elastic member 70, the included angle A decreases from 75 degrees to 70 degrees, and the rotation angle B increases from 80 degrees to 83 degrees. When the force F is removed, the contact finger elastic member 70 automatically resets under the action of its own spring force, so that the contact finger elastic member 70 returns to its initial state. At the same time, the included angle A becomes larger and larger, and the rotation angle B becomes smaller and smaller. That is, the included angle A of the contact finger elastic member 70 in the compressed state increases from 70 degrees to 75 degrees, and the rotation angle B decreases from 83 degrees to 80 degrees.

[0051] When the included angle A of the contact elastic element 70 is large, the contact elastic element 70 is difficult to compress; when the included angle A of the contact elastic element 70 is small, the spring force of the contact elastic element 70 is insufficient, that is, insufficient to ensure reliable contact between the contact elastic element 70 and the power contact pad of the circuit board, thus affecting current transmission. When the rotation angle B of the contact elastic element 70 is small, the contact elastic element 70 is difficult to compress; when the rotation angle B of the contact elastic element 70 is large, the spring force of the contact elastic element 70 is insufficient, insufficient to ensure reliable contact between the contact elastic element 70 and the power contact pad of the circuit board, thus affecting current transmission. The spring force of the contact elastic element 70 can be adjusted by adjusting its material and diameter. Under the condition that other factors remain unchanged, increasing the wire diameter of the material increases the spring force, and increasing the cutting modulus of the material also increases the spring force.

[0052] In this embodiment, the elastic ring 72 is a triangular ring, the positioning rod 721 is a straight rod, the abutting rod 723 is an arc-shaped rod, and the outer connecting rod 725 and the inner connecting rod 727 are both inclined rods. The included angle between the positioning rod 721 and the outer connecting rod 725 is greater than 0 degrees and less than 90 degrees, and the included angle between the positioning rod 721 and the inner connecting rod 727 is greater than 0 degrees and less than 90 degrees. Specifically, the positioning rod 721 and the outer connecting rod 725 are connected by an arc transition, that is, the positioning rod 721 and the outer connecting rod 725 are connected by an arc rod, and the positioning rod 721 and the inner connecting rod 727 are connected by an arc transition. Preferably, the finger elastic element 70 is formed by bending an elastic wire into multiple triangular elastic rings 72, and the multiple elastic rings 72 are arranged around the circumference of the first conductive part 42, and the opposite ends of the elastic wire are welded together.

[0053] Because the abutment ring 724 of the contact elastic element 70 makes planar contact with the power contact pad of the circuit board, the axis of the abutment ring 724 is allowed to offset to a certain extent relative to the axis of the power contact pad, in order to compensate for assembly errors of the entire system and thus achieve a reliable connection. The spring force of the contact elastic element 70 is adjusted by the flexibility of the material of the elastic ring 72 and the density of the elastic ring 72 to meet the needs of different scenarios.

[0054] like Figure 2 and Figure 10 As shown, the signal terminal 50 also includes a second connecting boss 53 disposed between the first signal connection section 52 and the second signal connection section 54. The second connecting boss 53 can be positioned on the second positioning step 262. In this embodiment, the first signal connection section 52 is an elastic pin, which elastically abuts against the signal contact plate of the circuit board. Specifically, the first signal connection section 52 includes a guide cylinder 521 disposed at one end of the signal terminal 50, a pin 523 inserted in the guide cylinder 521, and an elastic member connected between the guide cylinder 521 and the pin 523. The elastic member is used to elastically abut against the pin 523. The second signal connection section 54 includes a plug-in cylinder 542 connected to the end of the guide cylinder 521 opposite to the ejector pin 523 and multiple signal guide pieces 544. The signal guide pieces 544 are arc-shaped, and are arranged in a circle around the plug-in cylinder 542. The multiple signal guide pieces 544 and the plug-in cylinder 542 are used for mating with the signal terminals of the connector plug, and the multiple signal guide pieces 544 together grip the signal terminals. In this embodiment, the end of the plug-in cylinder 542 opposite to the first signal connection section 52 has two signal guide pieces 544, which are arranged opposite to each other and together grip the signal terminals. Since the signal terminals are configured as elastic ejector pins, the elastic ejector pins can also have planar contact with the signal contact pad of the circuit board, allowing a certain degree of offset between the axis of the ejector pin 523 and the axis of the signal contact pad to compensate for assembly errors in the entire system, thereby achieving a reliable connection. Furthermore, since both the first signal connection segment 52 and the contact finger elastic element 70 are elastic, contact damage during assembly can be effectively reduced. For example... Figure 2As shown, after power terminals 40 and signal terminals 50 are respectively installed in the first positioning hole 25 and the second positioning hole 26 of the connector core 20, adhesive is filled into the waterproof cavity 223 and cured to form a waterproof adhesive 60. The waterproof adhesive 60 forms a first clearance hole 62 around the first conductive part 42 and a second clearance hole 64 on the circumferential surface of the guide cylinder 521. The adhesive can be cured at room temperature or accelerated by heating. The waterproof adhesive 60 serves to fix and seal the power terminals 40 and the signal terminals 50. In this embodiment, first clearance holes 62 are formed around the two power terminals 40 on the waterproof adhesive 60, and second clearance holes 64 are formed around the first clearance holes 62 on the waterproof adhesive 60.

[0055] The sealing gasket 80 has a through hole 82 in the middle, and the first connecting part 22 is inserted into the through hole 82. The sealing gasket 80 is attached to the surface of the positioning part 27 away from the second connecting part 24. Specifically, the shape of the sealing gasket 80 is the same as the shape of the positioning part 27. In this embodiment, the sealing gasket 80 is a rectangular plate, and through holes 84 are provided at the four corners of the sealing gasket 80. When the sealing gasket 80 is fitted onto the first connecting part 22, the four through holes 84 are respectively aligned with the four first connecting holes 272.

[0056] like Figure 2 and Figure 11As shown, when assembling connector 100, the positioning rings 722 of the two contact elastic elements 70 are respectively engaged with the second connection holes 424 of the two power terminals 40. Specifically, by squeezing the outer connecting rod 725 of the contact elastic element 70, the contact elastic element 70 is contracted towards its central axis. When the maximum outer diameter of the bottom positioning ring 722 is smaller than the opening diameter of the second connection hole 424 of the power terminal 40, the contact elastic element 70 can be inserted into the second connection hole 424. Then, the contact elastic element 70 rebounds and resets towards its central axis under its own elastic force. At this time, the outer connecting rod 725 of the contact elastic element 70 contacts the inner circumferential surface of the second connection hole 424. Because the inner circumferential surface of the second connection hole 424 of the power terminal 40 is inclined, that is, the inner circumferential surface of the second connection hole 424 is an acute angle, and the angle A between the first plane where the outer connecting rod 725 and the positioning rod 721 of the contact elastic member 70 are located and the second plane where the positioning ring 722 is located is an acute angle, the opening diameter of the second connection hole 424 is smaller than the maximum outer contour diameter of the positioning ring 722 at the bottom of the contact elastic member 70, thereby preventing the contact elastic member 70 from detaching from the power terminal 40. Insert the second conductive portions 44 of the two power terminals 40 into the two first positioning holes 25 of the connector core 20, until the positioning boss 422 of the power terminal 40 abuts against the bottom surface of the waterproof cavity 223, the first connecting boss 452 is positioned at the first positioning step 252, the second conductive portion 44 is housed in the inner cavity of the first positioning cylinder 244, the second conductive portion 44 abuts against the first abutting step 2443, and the inner cavity of the second conductive portion 44 is directly opposite the first opening 2441 of the first positioning cylinder 244; insert the second signal connecting segments 54 of the six signal terminals 50 into the six second positioning holes 26 of the connector core 20, until the second connecting boss 53 of the signal terminal 50 is positioned at the second positioning step 262, and the second signal connecting segments 54 are housed in the inner cavities of the corresponding second positioning cylinders 246, the second The signal connection segment 54 abuts against the second abutment step 2463, and the second opening 2461 of the second positioning cylinder 246 faces the inner cavity of the second signal connection segment 54. At this time, the end of the first conductive part 42 facing away from the second conductive part 44 is housed in the waterproof cavity 223, and the end of the first signal connection segment 52 facing away from the second signal connection segment 54 is housed in the waterproof cavity 223. The end face of the first connecting part 22 of the connector 100 facing away from the second connecting part 24 is placed downwards, and glue is poured into the waterproof cavity 223 and cured to form a waterproof colloid 60 until the side of the waterproof colloid 60 facing away from the second connecting part 24 is flush with the end face of the first connecting part 22 facing away from the second connecting part 24. The sealing gasket 80 is fitted onto the first connecting part 22, and the four through holes 84 of the sealing gasket 80 are respectively aligned with the four first connecting holes 272. At this time, the first conductive part 42 and the first signal connection segment 52 are exposed on the side of the waterproof colloid 60 facing away from the second connecting part 24.To prevent adhesive from entering the interior of the power terminal 40 and the signal terminal 50, and to avoid affecting the compression and deformation of the power terminal 40 and the signal terminal 50, specifically, one end of the first conductive part 42 facing away from the second conductive part 44 is exposed to the surface of the waterproof adhesive 60 facing away from the second connecting part 24, and one end of the first signal connecting section 52 facing away from the second signal connecting section 54 is exposed to the surface of the waterproof adhesive 60 facing away from the second connecting part 24, so as to prevent the adhesive of the waterproof adhesive 60 from flowing into the contact finger elastic member 70 of the power terminal 40 and the elastic member between the guide cylinder 521 and the ejector pin 523 of the signal terminal 50, thus affecting the compression of the contact finger elastic member 70 and the elastic member.

[0057] When it is necessary to remove the contact finger elastic element 70 from the power terminal 40, the contact finger elastic element 70 is retracted towards its central axis by squeezing the outer connecting rod 725 of the contact finger elastic element 70; when the maximum outer contour diameter of the bottom positioning ring 722 is smaller than the opening diameter of the second connecting hole 424 of the power terminal 40, the contact finger elastic element 70 can be removed by applying a force away from the power terminal 40.

[0058] like Figure 12 As shown, the circuit board 200 can be installed in an electronic device such as a battery or host. The circuit board 200 is provided with a power contact plate 202 and a signal contact plate 204. In this embodiment, one side of the circuit board 200 is provided with two power contact plates 202 spaced apart from each other and six signal contact plates 204 spaced apart from each other. One signal contact plate 204 is located on one side of the two power contact plates 202, and the five signal contact plates 204 are located on the opposite side of the two power contact plates 202.

[0059] like Figure 2 and Figure 13 As shown, when using connector 100, connector 100 is installed in the housing of electronic device, such that sealing gasket 80 is clamped between housing and positioning part 27. Four fasteners pass through the four first connection holes 272 and four through holes 84 of positioning part 27 and are locked to housing. First connection part 22 extends into the interior of housing, such that two power contact pads 202 abut against the two power contact pads 202 of circuit board 200, such that the included angle A of the contact elastic member 70 becomes smaller and the rotation angle B of the contact elastic member 70 becomes larger, and the abutting ring 724 of the contact elastic member 70 moves closer to the positioning ring 722. Six signal terminals 50 abut against the six signal contact pads 204 of circuit board 200, and pin 523 is pushed to compress the elastic member between guide cylinder 521 and pin 523. Second connection part 24 protrudes outside housing to facilitate the insertion of external plug.

[0060] The contact finger elastic element 70 of the connector 100 of this application directly abuts against the power contact plate 202, and the signal terminals 50 directly abut against the signal contact plate 204. Therefore, the wires between the connector 100 and the circuit board 200 are saved, avoiding the wires occupying the internal space of the housing, which is conducive to the miniaturization of electronic devices and reduces manufacturing costs. In addition, the connector 100 is directly mounted on the housing by fasteners, without the need for wires to be soldered to the circuit board 200, which makes it convenient to install or remove the connector 100 from the housing and is easy to operate.

[0061] Please refer to the following: Figure 14 and Figure 15 The connector structure in the second embodiment of this application is similar to that in the first embodiment, except that the shape of the elastic ring 72a of the contact elastic member 70a in the second embodiment is different from that of the elastic ring 72a in the first embodiment. Specifically, the elastic ring 72a is generally rectangular, and both the positioning rod 721 and the abutment rod 723 are straight rods. The axis of the abutment rod 723 is parallel to the axis of the positioning rod 721, and the length of the abutment rod 723 is less than the length of the positioning rod 721. When the abutment rod 723 abuts against the power contact plate, the contact area between the abutment rod 723 and the power contact plate is increased due to the straight nature of the abutment rod 723. This increases the contact reliability between the contact elastic member 70a and the power contact plate of the circuit board, and improves the overcurrent capability of the contact elastic member 70a. At the same time, because the abutment rod 723 is a straight rod, the power contact plate that contacts the abutment rod 723 needs to be designed with a larger area. The angle between the first plane containing the positioning rod 721 and the outer connecting rod 725 of the elastic ring 72a and the second plane containing the positioning ring 722 is larger than the angle A in the first embodiment. Preferably, the angle A between the first plane containing the positioning rod 721 and the outer connecting rod 725 of the elastic ring 72a and the second plane containing the positioning ring 722 is approximately 88 degrees. The positioning rod 721 and the abutment rod 723 of the same elastic ring 72a form a rotation angle B on the plane containing the abutment ring 724.

[0062] The method of installing the finger elastic member 70a to the connection hole of the power terminal, the method of removing the finger elastic member 70a from the power terminal, and the method of preventing the finger elastic member 70a from detaching from the power terminal in the second embodiment are the same as in the first embodiment, and will not be described again here.

[0063] When a force F is applied to the abutment ring 724, the abutment ring 724 of the contact finger elastic member 70a moves towards the positioning ring 722, while the included angle A becomes smaller and the rotation angle B becomes larger and larger, until the spring force of the contact finger elastic member 70a along its axis is balanced with the applied force F; when the force F is removed, the contact finger elastic member 70a automatically resets under its own spring force, so that the contact finger elastic member 70a returns to its initial state, while the included angle A becomes larger and the rotation angle B becomes smaller and smaller.

[0064] Please refer to the following: Figure 16 and Figure 17The connector structure in the third embodiment of this application is similar to that in the first embodiment, except that the shape of the elastic ring 72b of the finger elastic member 70b in the third embodiment is different from that of the elastic ring 72 in the first embodiment. Specifically, the middle part of the outer connecting rod 725 in the third embodiment is bent towards the inner connecting rod 727, and the middle part of the inner connecting rod 727 is bent towards the outer connecting rod 725. In this embodiment, the end of the outer connecting rod 725 near the positioning rod 721 is bent towards the inner connecting rod 727, and the end of the inner connecting rod 727 near the abutment rod 723 is bent towards the outer connecting rod 725. The compression deformation of the finger elastic member 70b is achieved by bending and deforming both the outer connecting rod 725 and the inner connecting rod 727 towards the elastic ring 72b. Both the abutment rod 723 and the positioning rod 721 are straight rods to increase the reliability of contact between the positioning rod 721 and the power contact plate of the circuit board; the end of the outer connecting rod 725 near the abutment rod 723 is inclined to the axis of the abutment rod 723. In the third embodiment, the angle A between the first plane where the interconnected outer connecting rod 725 and the positioning rod 721 are located and the second plane where the positioning ring 722 is located is close to 90 degrees or equal to 90 degrees, that is, the angle A can be, but is not limited to, 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees or 90 degrees; in this embodiment, the angle A is 87 degrees. Understandably, in the third embodiment, the outer connecting rod 725 is a wavy rod. Specifically, the outer connecting rod 725 bends towards the inner connecting rod 727 near the positioning rod 721, and the end of the outer connecting rod near the abutment rod 723 bends towards one side of the inner connecting rod 727. Therefore, there are two bends on the outer connecting rod 725, making the outer connecting rod 725 a wavy rod. The middle part of the inner connecting rod 727 bends towards the outer connecting rod 725 to form a bend. In the third embodiment, the spring force of the finger elastic element 70b is determined by the bending of the outer connecting rod 725 and the inner connecting rod 727. That is, the compression deformation of the finger elastic element 70b is achieved by the deformation of one bend in the inner connecting rod 727 and the deformation of two bends in the outer connecting rod 725. When an external force F is applied to the abutment ring 724 of the finger elastic element 70b, the two bends on the outer connecting rod 725 and the bends on the inner connecting rod 727 are compressed and deformed, causing the included angle of these bends to decrease. This results in the abutment ring 724 of the finger elastic element 70b approaching the positioning ring 722 until the spring force of the finger elastic element 70b is balanced with the external force F, at which point the finger elastic element 70b is no longer compressed. When the external force F is removed, the finger elastic element 70b returns to its initial state under the action of its own spring force.In the third embodiment, the compression of the contact elastic element 70b is achieved by the bending deformation of the outer connecting rod 725 and the inner connecting rod 727. An external force F is applied to the abutment ring 724 of the contact elastic element 70b to press the bent sections of the outer connecting rod 725 and the inner connecting rod 727, making the included angles of the bent sections of the outer connecting rod 725 and the inner connecting rod 727 smaller. This causes the abutment ring 724 to move closer to the positioning ring 722 until the contact elastic element 70b is balanced with the external force F, at which point the contact elastic element 70b is no longer compressed. The maximum compression of the contact elastic element 70b is greater, making it suitable for applications where the assembly tolerances of connectors and contact pads are large.

[0065] In this embodiment, the inclination angle of the inner circumferential surface of the power terminal connection hole is consistent with the inclination angle of the outer side surface of the outer connecting rod 725 of the finger elastic member 70b.

[0066] When the contact elastic element 70b is installed into the connection hole of the power terminal, the contact elastic element 70b is compressed towards its central axis by pressing the end of the outer connecting rod 725 of the contact elastic element 70b near the positioning rod 721. When the maximum outer diameter of the bottom positioning ring 722 is smaller than the opening diameter of the connection hole of the power terminal, the contact elastic element 70b can be inserted into the connection hole of the power terminal. Then, the contact elastic element 70b springs back to its original position outward under its own elastic force. At this time, the outer connecting rod 725 of the contact elastic element 70b contacts the inner circumferential surface of the connection hole of the power terminal. Since the inner circumferential surface of the connection hole of the power terminal forms an acute angle with the bottom surface, and the outer connecting rod 725 of the contact elastic element 70b also forms an acute angle with the bottom positioning ring 722, the opening diameter of the connection hole of the power terminal is smaller than the maximum outer diameter of the positioning ring 722 at the bottom of the contact elastic element 70b, thereby preventing the contact elastic element 70b from detaching from the power terminal.

[0067] When removing the contact finger elastic element 70b from the power terminal, the contact finger elastic element 70b is retracted towards its central axis by squeezing the outer connecting rod 725 of the contact finger elastic element 70b. When the maximum outer contour diameter of the bottom positioning ring 722 is smaller than the opening diameter of the connection hole of the power terminal, a force away from the power terminal is applied to the contact finger elastic element 70b to remove the contact finger elastic element 70b.
