Description

Technical Field

[0001] The invention relates to the technical field of electrical connectors, and in particular to a connector. Background Art

[0002] Connectors can be widely used in various types of vehicles, communications, computers and other consumer electronics, industry, transportation and other fields. The various types of vehicles that can be applied include new energy vehicles, electric bicycles, electric motorcycles, electric scooters, etc. Connector plugs and connector sockets, as key components, can build a bridge of communication between circuits, allowing current to flow and enabling the circuit to achieve the predetermined function.

[0003] Existing battery external connectors generally use wires extending from the rear of the connector to connect to the circuit board inside the battery; however, the wires between the circuit board inside the battery and the connector will occupy the size space inside the battery, which is not conducive to the miniaturization of the battery. Summary of the invention

[0004] The object of the present invention is to provide a connector.

[0005] The present invention provides a connector, including a connector core, a power terminal and a signal terminal, wherein the connector core includes a first connecting portion located at one end thereof, and a first positioning hole and a second positioning hole are provided on the first connecting portion and are spaced and parallel to each other, and the first positioning hole and the second positioning hole both pass through the connector core; the power terminal is positioned at the first positioning hole, and the power terminal includes a first conductive portion and a second conductive portion located at opposite ends thereof, and the first conductive portion and the second conductive portion are respectively exposed at opposite ends of the first positioning hole, and the first conductive portion is used to abut against a power contact plate; the signal terminal is positioned at the second positioning hole, and the signal terminal includes a first signal connecting section and a second signal connecting section located at opposite ends thereof, and the first signal connecting section and the second signal connecting section are respectively exposed at opposite ends of the second positioning hole, and the first signal connecting section is used to abut against the signal contact plate.

[0006] When the connector of the present application is connected to an electronic product such as a battery, the first conductive portion of the power terminal of the connector directly abuts against the power contact plate on the circuit board inside the electronic product, and the first signal connection section of the signal terminal directly abuts against the signal contact plate on the circuit board; therefore, the connector can save the wires between it and the circuit board, which not only avoids the wires occupying the internal space of the electronic product, but also is conducive to the miniaturization of the electronic product and reduces the manufacturing cost.

[0032] like Figure 2-Figure 4 As shown, the connector core 20 also includes a positioning portion 27 connected between the first connection portion 22 and the second connection portion 24. The positioning portion 27 is used to fix the connector 100 to the electronic product. The first connection portion 22 is convexly arranged on one side of the positioning portion 27, and the second connection portion 24 is convexly arranged on the other side of the positioning portion 27. In this embodiment, the positioning portion 27 is a rectangular plate, and the first connection portion 22 and the second connection portion 24 are both cylindrical. The axis of the first connection portion 22 is collinear with the axis of the second connection portion 24. The diameter of the first connection portion 22 is equal to or unequal to the diameter of the second connection portion 24. Generally, the diameter of the first connection portion 22 is close to the diameter of the second connection portion 24; optionally, the diameter of the first connection portion 22 is equal to the diameter of the second connection portion 24. The first connection part 22 and the second connection part 24 protrude from the surrounding of the positioning part 27 in the radial direction of the first connection part 22, and the first connection holes 272 are respectively provided at the four corners of the positioning part 27, and the axis of the first positioning hole 25 and the axis of the second positioning hole 26 are parallel to the axis of the first connection part 22. In other embodiments, the positioning part 27 can be, but is not limited to, a circular plate, an elliptical plate, a polygonal plate, etc.

[0033] Optionally, the first connection portion 22 is provided with a first positioning step 252 on the inner circumference of the first positioning hole 25.

[0034] 253, the first positioning section 251 is located on the first connection part 22 and passes through the first connection part 22, the end of the second positioning section 253 away from the first positioning section 251 passes through the positioning part 27, the inner diameter of the first positioning section 251 is greater than the inner diameter of the second positioning section 253 to form a first positioning step 252. The first connection part 22 is provided with a second positioning step 262 on the inner circumferential surface of the second positioning hole 26. Specifically, the second positioning hole 26 includes a third positioning section 261 and a fourth positioning section 263 that are axially connected. The third positioning section 261 is located on the first connection part 22 and passes through the first connection part 22, the end of the fourth positioning section 263 away from the third positioning section 261 passes through the positioning part 27, the inner diameter of the third positioning section 261 is greater than the inner diameter of the fourth positioning section 263 to form a second positioning step 262. The end surface of the first connection part 22 away from the second connection part 24 is provided with a waterproof cavity 223, and the waterproof cavity 223 communicates with 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 colinear with the axis of the first connecting part 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 circumference of the first connecting part 22 is provided with an anti-fool surface 226, and the anti-fool surface 226 is used to prevent the connector rubber core 20 from being reversely inserted. The inner circumference of the waterproof cavity 223 may be an inclined surface or a straight surface, that is, the inner circumference of the waterproof cavity 223 is inclined or parallel to the axis of the first connecting part 22. Due to the manufacturing process requirements of the connector rubber core 20, such as whether a draft angle can be left or not during mold injection, or the inner circumference of the waterproof cavity 223 produced by mechanical processing or other processes for the connector rubber core 20 can also be internally inclined or straight. Preferably, the inner circumference of the waterproof cavity 223 of the first connection part 22 is inclined relative to the axis of the first connection part 22. Specifically, the side of the inner circumference close to the second connection part 24 is farther away from the axis of the first connection part 22 than the side far away from the second connection part 24, that is, the inner diameter of the end of the inner circumference close to the second connection part 24 is greater than the inner diameter of the end far away from the second connection part 24; the inner circumference of the waterproof cavity 223 of the first connection part 22 is set to be inwardly inclined, which can prevent the glue layer filled in the waterproof cavity 223 from falling out.

[0035] Optionally, the second connection part 24 includes a connection sleeve 242, a first positioning cylinder 244 and a second positioning cylinder 246, which are arranged around the end surface of the positioning part 27 away from the first connection part 22; the first positioning cylinder 244 and the second positioning cylinder 246 are both located in the connection sleeve 242, one end of the first positioning cylinder 244 is connected to the end surface of the positioning part 27 away from the first connection part 22 and is arranged around the first positioning hole 25, and one end of the second positioning cylinder 246 is connected to the end surface of the positioning part 27 away from the first connection part 22 and is arranged around the second positioning hole 26.

[0036] like Figure 4-Figure 9 As shown, the power terminal 40 further includes a third connecting portion 45 connected to the first conductive portion 42 and the second conductive portion 44, and 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 at 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 a cylinder, 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 other end opposite to the third connecting portion 45, the diameter of the first conductive portion 42 is greater than the diameter of the third connecting portion 45, so that a positioning boss 422 is formed between the first conductive portion 42 and the third connecting portion 45; the diameter of the third connecting portion 45 is greater than the diameter of the second conductive portion 44, so that a first connecting boss 452 is formed between the third connecting portion 45 and the second conductive portion 44. In this embodiment, the outer circumference of the second conductive portion 44 is provided with at least one circle of barbs 442, and the barbs 442 are used to locate to the inner circumference of the first positioning hole 25. In other embodiments, the outer circumference of the third connecting portion 45 is provided with at least one circle of barbs, and the barbs are used to locate to the inner circumference of the first positioning section 251 of the first positioning hole 25. In other embodiments, the outer circumference of the second conductive portion 44 and the outer circumference of the third connecting portion 45 are respectively provided with at least one circle of barbs, and the barbs are used to locate to the inner circumference of the first positioning hole 25.

[0037] Optionally, the second conductive portion 44 includes a plurality of conductive sheets 444 disposed at an end of the third connecting portion 45 away from the first conductive portion 42, and the plurality of conductive sheets 444 are arranged in a circle around the circumference of the third connecting portion 45 to form a first plug hole 445, and the first plug hole 445 is used for inserting an external power conductive pin. In this embodiment, the conductive sheet 444 is an arc-shaped sheet, and the plurality of conductive sheets 444 are evenly spaced and arranged in a circle around the circumference of the third connecting portion 45.

[0038] like Figure 5 and Figure 8-Figure 9 As shown, the connector 100 also includes a conductive contact elastic member 70. The contact elastic member 70 is made of a highly conductive and highly elastic spring wire, which can be made by twisting and bending a single spring wire with a spring machine, and then welding or bonding the ends of the spring wire together. The contact elastic member 70 is connected to the first conductive portion 42, and the contact elastic member 70 is used to elastically press against the power contact plate of the circuit board. Specifically, one end of the contact elastic member 70 is clamped in the connecting tube, and the other end of the contact elastic member 70 can elastically press against the power contact plate. In this embodiment, the end surface of the first conductive portion 42 facing away from the second conductive portion 44 is provided with a second connecting hole 424, and one end of the contact elastic member 70 is clamped in the second connecting hole 424. The finger contact elastic member 70 includes a plurality of elastic rings 72, which are arranged in a circle around the circumference of the connecting tube; when the finger contact elastic member 70 is clamped in the second connecting hole 424 of the first conductive part 42, the axis of the finger contact elastic member 70 is colinear with the axis of the first conductive part 42 (that is, the connecting tube), and the end of the finger contact elastic member 70 away from the second conductive part 44 extends out of the connecting tube. Figure 7 As shown, the angle θ between the inner circumference and the bottom surface of the second connection hole 424 of the first conductive part 42 is less than 90 degrees, specifically, the angle θ is greater than 45 degrees and less than 90 degrees; in this embodiment, the angle θ of the first conductive part 42 is 60 degrees.

[0039] Specifically, the elastic ring 72 includes a positioning rod 721, a push rod 723, an outer connecting rod 725 and an inner connecting rod 727. The positioning rod 721 and the push 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 end of the positioning rod 721 and the outer end of the push rod 723. The opposite ends of the inner connecting rod 727 are respectively connected to the inner end of the positioning rod 721 and the inner end of the push rod 723. The positioning rod 721 is used to push against the bottom surface of the second connecting hole 424 of the first conductive part 42. The end of the outer connecting rod 725 close to the positioning rod 721 pushes against the inner circumference of the second connecting hole 424. The inner connecting rod 727 is far away from the inner circumference of the second connecting hole 424. The push rod 723 pushes against the power contact plate. The angle between the positioning rod 721 and the outer connecting rod 725 of the elastic ring 72 can be consistent with or inconsistent with the angle θ of the first conductive part 42. When the installation space of the contact finger elastic member 70 is small, the angle θ of the first conductive portion 42 can be larger; when the installation space of the contact finger elastic member 70 is large, the angle θ of the first conductive portion 42 can be smaller.

[0040] Optionally, a plurality of positioning rods 721 surround a positioning ring 722, and the positioning ring 722 is positioned in the second connection hole 424 of the first conductive part 42. The outer contour of the contact finger elastic member 70 is conical. From the side angle of the contact finger elastic member 70, the outer connecting rod 725 and the adjacent positioning rod 721 are inclined along the same side relative to the plane where the positioning ring 722 is located, and the plane through 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 outer connecting rod 725 and the positioning rod 721 connected to each other are located and the second plane where the positioning ring 722 is located forms an angle A, and the angle range of 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. A plurality of abutting rods 723 form an abutting ring 724, the abutting ring 724 exposes the first conductive part 42 (i.e., the connecting tube), and the abutting ring 724 rotates a certain rotation angle B relative to the positioning ring 722, and the value range of the rotation angle B is between 30 degrees and 50 degrees; specifically, the positioning rods 721 and the abutting rods 723 of the same elastic ring 72 form a rotation angle B on the plane where the abutting ring 724 is located, and the angle of the rotation angle B is greater than 30 degrees and less than 50 degrees. That is, the angle of the 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 angle A of the touch finger elastic member 70 is 80 degrees, and the angle of the rotation angle B of the touch finger elastic member 70 is 35 degrees.

[0041] When force F is applied to the abutting ring 724, the abutting ring 724 of the contact finger elastic member 70 moves toward the direction of approaching the positioning ring 722, and at the same time, the 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 axial direction is balanced with the applied force F; that is, if the initial state of the 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 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 the initial state, and at the same time, the angle A becomes larger and larger, and the rotation angle B becomes smaller and smaller, that is, the 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.

[0042] When the angle A of the contact finger elastic member 70 is large, the contact finger elastic member 70 is difficult to compress; when the angle A of the contact finger elastic member 70 is small, the spring force of the contact finger elastic member 70 is insufficient, that is, it is not enough to make the contact finger elastic member 70 reliably contact with the power contact plate of the circuit board, thereby affecting the current transmission. When the rotation angle B of the contact finger elastic member 70 is small, the contact finger elastic member 70 is difficult to compress; when the rotation angle B of the contact finger elastic member 70 is large, the spring force of the contact finger elastic member 70 is insufficient, and it is not enough to make the contact finger elastic member 70 reliably contact with the power contact plate of the circuit board, thereby affecting the current transmission. The spring force of the contact finger elastic member 70 can be adjusted by adjusting its material and diameter, etc. Under the condition that other conditions remain unchanged, increasing the material wire diameter increases the elastic force, and increasing the material trimming modulus increases the elastic force.

[0043] 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 rod, the outer connecting rod 725 and the inner connecting rod 727 are both inclined rods, the angle between the positioning rod 721 and the outer connecting rod 725 is greater than 0 degrees and less than 90 degrees, and the 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 in 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 in an arc transition, that is, the positioning rod 721 and the inner connecting rod 727 are connected by an arc rod. Preferably, the finger contact elastic member 70 is bent into a plurality of triangular elastic rings 72 by an elastic wire, and the plurality of elastic rings 72 are arranged around the circumference of the first conductive portion 42, and the opposite ends of the elastic wire are welded.

[0044] Since the top ring 724 of the contact finger elastic member 70 is in plane contact with the power contact plate of the circuit board, the axis of the top ring 724 is allowed to deviate to a certain extent relative to the axis of the power contact plate to compensate for the assembly error of the entire system, thereby achieving reliable connection. The spring force of the contact finger elastic member 70 is adjusted by the flexibility of the material of the elastic ring 72 and the density of a circle of the elastic ring 72 to meet the needs of different scenarios.

[0045] like Figure 2 and Fig.10 As shown, the signal terminal 50 also includes a second connecting boss 53 disposed between the first signal connecting section 52 and the second signal connecting section 54, and the second connecting boss 53 can be positioned on the second positioning step 262; in this embodiment, the first signal connecting section 52 is an elastic ejector pin, and the elastic ejector pin elastically presses against the signal contact plate of the circuit board. Specifically, the first signal connecting section 52 includes a guide slide cylinder 521 disposed at one end of the signal terminal 50, an ejector pin 523 inserted in the guide slide cylinder 521, and an elastic member connected between the guide slide cylinder 521 and the ejector pin 523, and the elastic member is used to elastically press against the ejector pin 523. The second signal connection section 54 includes a plug-in tube 542 connected to the end of the guide slide tube 521 away from the ejector pin 523 and a plurality of signal guide pieces 544. The signal guide piece 544 is an arc-shaped piece. The plurality of signal guide pieces 544 are arranged in a circle around the plug-in tube 542. The plurality of signal guide pieces 544 and the plug-in tube 542 are used for plug-in connection with the signal docking terminal of the connector plug. The plurality of signal guide pieces 544 hold the signal docking terminal together. In this embodiment, two signal guide pieces 544 are provided at the end of the plug-in tube 542 away from the first signal connection section 52. The two signal guide pieces 544 are arranged opposite to each other. The two signal guide pieces 544 hold the signal docking terminal together. Since the signal terminal is set as an elastic ejector pin, the elastic ejector pin can also be in planar contact with the signal contact disk of the circuit board, allowing the axis of the ejector pin 523 to deviate to a certain extent relative to the axis of the signal contact disk to compensate for the assembly error of the entire system, thereby achieving reliable connection. In addition, since the first signal connection section 52 and the contact finger elastic member 70 are both elastic, contact damage during the assembly process can be effectively reduced. Figure 2As shown, after the power terminal 40 and the signal terminal 50 are installed in the first positioning hole 25 and the second positioning hole 26 of the connector rubber core 20, glue is filled in the waterproof cavity 223 and cured to form a waterproof colloid 60, so that the waterproof colloid 60 forms a first avoidance hole 62 around the first conductive part 42 and a second avoidance hole 64 on the circumference of the guide slide cylinder 521. The above-mentioned glue curing can be static curing at room temperature, or it can be accelerated by heating. The waterproof colloid 60 plays the role of fixing and sealing the power terminal 40 and the signal terminal 50. In this embodiment, the first avoidance holes 62 are respectively formed around the two power terminals 40 on the waterproof colloid 60, and the second avoidance holes 64 are respectively formed around the first avoidance holes 62 on the waterproof colloid 60.

[0046] A through hole 82 is provided in the middle of the sealing gasket 80, and the first connecting portion 22 is inserted into the through hole 82. The sealing gasket 80 is attached to the surface of the positioning portion 27 away from the second connecting portion 24. Specifically, the shape of the sealing gasket 80 is the same as that of the positioning portion 27. In this embodiment, the sealing gasket 80 is a rectangular plate, and the four corners of the sealing gasket 80 are respectively provided with through holes 84. When the sealing gasket 80 is sleeved on the first connecting portion 22, the four through holes 84 are respectively opposite to the four first connecting holes 272.

[0047] like Figure 2 and Fig.11As shown, when assembling the connector 100, the positioning rings 722 of the two contact elastic members 70 are respectively clamped in the second connection holes 424 of the two power terminals 40; specifically, by squeezing the outer connecting rod 725 of the contact elastic member 70, the contact elastic member 70 is contracted toward its axis as a whole; when the maximum outer contour diameter of the positioning ring 722 at the bottom is smaller than the mouth diameter of the second connection hole 424 of the power terminal 40, the contact elastic member 70 can be installed into the second connection hole 424, and then the contact elastic member 70 rebounds and resets to the outside of its axis under the action of its own elastic force, and at this time, the outer connecting rod 725 of the contact elastic member 70 is in contact with the inner circumference of the second connection hole 424. Since the inner circumference of the second connecting hole 424 of the power terminal 40 is inclined, that is, the inner circumference of the second connecting 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 finger elastic member 70 are located and the second plane where the positioning ring 722 is located is an acute angle, the mouth diameter of the second connecting hole 424 is smaller than the maximum outer contour diameter of the positioning ring 722 at the bottom of the contact finger elastic member 70, thereby preventing the contact finger 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 respectively, 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 on the first positioning step 252, the second conductive portion 44 is accommodated 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 faces the first opening 2441 of the first positioning cylinder 244; insert the second signal connecting sections 54 of the six signal terminals 50 into the six second positioning holes 26 of the connector core 20 respectively, until the second connecting boss 53 of the signal terminal 50 is positioned on the second positioning step 262, the second signal connecting section 54 is accommodated in the inner cavity of the corresponding second positioning cylinder 246, and the second The signal connection section 54 abuts against the second abutting step 2463, and the second opening 2461 of the second positioning tube 246 faces the inner cavity of the second signal connection section 54; at this time, the end of the first conductive part 42 facing away from the second conductive part 44 is accommodated in the waterproof cavity 223, and the end of the first signal connection section 52 facing away from the second signal connection section 54 is accommodated in the waterproof cavity 223; the first connection part 22 of the connector 100 is placed with the end face facing away from the second connection part 24 downward, 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 connection part 24 is flush with the end face of the first connection part 22 facing away from the second connection part 24; the sealing gasket 80 is sleeved on the first connection part 22, and the four through holes 84 of the sealing gasket 80 are respectively facing the four first connection holes 272.

[0048] The first conductive part 42 and the first signal connection section 52 expose the side of the waterproof colloid 60 away from the second connection part 24. In order to prevent glue from entering the inside of the power terminal 40 and the signal terminal 50, and avoid affecting the compression deformation of the power terminal 40 and the signal terminal 50; specifically, the end of the first conductive part 42 away from the second conductive part 44 exposes the surface of the waterproof colloid 60 away from the second connection part 24, and the end of the first signal connection section 52 away from the second signal connection section 54 exposes the surface of the waterproof colloid 60 away from the second connection part 24, so as to prevent the glue of the waterproof colloid 60 from flowing into the contact finger elastic member 70 of the power terminal 40 and the elastic member between the guide slide cylinder 521 and the ejector pin 523 of the signal terminal 50, and affecting the compression of the contact finger elastic member 70 and the elastic member.

[0049] When it is necessary to remove the contact finger elastic member 70 from the power terminal 40, the outer connecting rod 725 of the contact finger elastic member 70 is squeezed so that the contact finger elastic member 70 as a whole shrinks toward its axis; when the maximum outer contour diameter of the bottom positioning ring 722 is smaller than the mouth diameter of the second connecting hole 424 of the power terminal 40, a force is applied to the contact finger elastic member 70 away from the power terminal 40 to remove the contact finger elastic member 70.

[0050] like Fig.12 As shown, the circuit board 200 can be arranged in an electronic device such as a battery or a host, and a power contact plate 202 and a signal contact plate 204 are provided on the circuit board 200. In this embodiment, two power contact plates 202 spaced apart from each other and six signal contact plates 204 spaced apart from each other are provided on one side of the circuit board 200, one signal contact plate 204 is located on one side of the two power contact plates 202, and five signal contact plates 204 are located on the other side opposite to the two power contact plates 202.

[0051] like Figure 2 and Fig.13 As shown, when the connector 100 is used, the connector 100 is installed in the housing of the electronic device so that the sealing gasket 80 is clamped between the housing and the positioning portion 27, and the four locking members are respectively passed through the four first connecting holes 272 and the four through holes 84 of the positioning portion 27 and then locked in the housing, and the first connecting portion 22 extends to the inside of the housing so that the two power contact plates 202 are respectively pressed against the two power contact plates 202 of the circuit board 200, so that the angle A of the contact finger elastic member 70 becomes smaller, and the rotation angle B of the contact finger elastic member 70 becomes larger, and the pressing circle 724 of the contact finger elastic member 70 approaches the positioning circle 722; the six signal terminals 50 are respectively pressed against the six signal contact plates 204 of the circuit board 200, and the ejector pin 523 is pushed to squeeze the elastic member between the guide slide cylinder 521 and the ejector pin 523; the second connecting portion 24 is exposed outside the housing to facilitate the insertion of an external plug.

[0052] The contact finger elastic member 70 of the connector 100 of the present application directly abuts against the power contact disk 202, and the signal terminals 50 directly abut against the signal contact disk 204 respectively. Therefore, the wires between the connector 100 and the circuit board 200 are saved, and the wires are prevented from occupying the internal space of the shell, which is conducive to the miniaturization of electronic equipment and reduces manufacturing costs. In addition, the connector 100 is directly installed on the shell through a locking piece, and there is no need to weld the wires to the circuit board 200, which makes it convenient to install or remove the connector 100 to the shell and is easy to operate.

[0053] Please also read Fig.14 and Fig.15 The structure of the connector in the second embodiment of the present application is similar to that of the connector in the first embodiment, except that the shape of the elastic ring 72a of the contact finger elastic member 70a in the second embodiment is different from that of the elastic ring 72 in the first embodiment; specifically, the elastic ring 72a is roughly a rectangular ring, the positioning rod 721 and the abutting rod 723 are both straight rods, the axis of the abutting rod 723 is parallel to the axis of the positioning rod 721, and the length of the abutting rod 723 is less than the length of the positioning rod 721. When the abutting rod 723 abuts against the power contact plate, since the abutting rod 723 is a straight rod, the contact area between the abutting rod 723 and the power contact plate is increased, so as to increase the contact reliability between the contact finger elastic member 70a and the power contact plate of the circuit board, and improve the overcurrent capacity of the contact finger elastic member 70a; at the same time, since the abutting rod 723 is a straight rod, the power contact plate in contact with the abutting rod 723 needs to be designed to have a larger area. The angle between the first plane where the positioning rod 721 and the outer connecting rod 725 of the elastic ring 72a are located and the second plane where the positioning ring 722 is located is larger than the angle A in the first embodiment. Preferably, the angle A between the first plane where the positioning rod 721 and the outer connecting rod 725 of the elastic ring 72a are located and the second plane where the positioning ring 722 is located is about 88 degrees. The positioning rod 721 and the abutting rod 723 of the same elastic ring 72a form a rotation angle B on the plane where the abutting ring 724 is located.

[0054] The method of installing the contact finger elastic member 70a to the connecting hole of the power terminal, the method of removing the contact finger elastic member 70a from the power terminal, and the method of preventing the contact finger elastic member 70a from detaching from the power terminal in the second embodiment are the same as those in the first embodiment and will not be repeated here.

[0055] When force F is applied to the abutting ring 724, the abutting ring 724 of the contact finger elastic member 70a moves toward the direction close to the positioning ring 722, and at the same time, the 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 70a along its axial direction is balanced with the applied force F; when the force F is removed, the contact finger elastic member 70a automatically resets under the action of its own spring force, so that the contact finger elastic member 70a returns to its initial state, and at the same time, the angle A becomes larger and larger, and the rotation angle B becomes smaller and smaller.

[0056] Please also read Fig.16 and Fig.17The structure of the connector in the third embodiment of the present application is similar to that of the connector in the first embodiment, except that the shape of the elastic ring 72b of the finger contact elastic member 70b in the third embodiment is different from that of the elastic ring 72 in the first embodiment; specifically, the middle portion of the outer connecting rod 725 in the third embodiment is bent toward the inner connecting rod 727, and the middle portion of the inner connecting rod 727 is bent toward the outer connecting rod 725. In this embodiment, the end of the outer connecting rod 725 close to the positioning rod 721 is bent toward the inner connecting rod 727, and the end of the inner connecting rod 727 close to the abutting rod 723 is bent toward the outer connecting rod 725. The compression deformation of the finger contact elastic member 70b is achieved by bending and deforming both the outer connecting rod 725 and the inner connecting rod 727 toward the elastic ring 72b. The push rod 723 and the positioning rod 721 are both straight rods to increase the contact reliability between the positioning rod 721 and the power contact plate of the circuit board; the end of the outer connecting rod 725 close to the push rod 723 is inclined to the axis of the push rod 723. The angle A between the first plane where the outer connecting rod 725 and the positioning rod 721 connected to each other in the third embodiment and the second plane where the positioning ring 722 is located is close to 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. It can be understood that the outer connecting rod 725 in the third embodiment is a wavy rod. Specifically, the outer connecting rod 725 is bent toward the inner connecting rod 727 near the positioning rod 721, and one end of the outer connecting rod near the abutting rod 723 is bent toward one side of the inner connecting rod 727. Therefore, two bends are provided on the outer connecting rod 725, so that the outer connecting rod 725 is a wavy rod; the middle part of the inner connecting rod 727 is bent toward the outer connecting rod 725 to form a bend. In the third embodiment, the spring force of the finger elastic member 70b is jointly determined by the bend of the outer connecting rod 725 and the bend of the inner connecting rod 727, that is, the compression deformation of the finger elastic member 70b is achieved by the deformation of one bend of the inner connecting rod 727 and the deformation of the two bends of the outer connecting rod 725. When the external force F is applied to the abutting ring 724 of the finger elastic member 70b, the two bends on the outer connecting rod 725 and the bend of the inner connecting rod 727 are pressed to deform, so that the angles of these bends become smaller, so that the abutting ring 724 of the finger elastic member 70b approaches the positioning ring 722, until the spring force of the finger elastic member 70b is balanced with the external force F, and the finger elastic member 70b is no longer compressed. When the external force F is removed, the finger elastic member 70b returns to the initial state under the action of its own spring force.The compression of the finger elastic member 70b in the third embodiment is achieved by the bending deformation of the outer connecting rod 725 and the inner connecting rod 727. The external force F applied to the top circle 724 of the finger elastic member 70b presses the bent section of the outer connecting rod 725 and the bent section of the inner connecting rod 727, so that the angle of the bent section of the outer connecting rod 725 and the angle of the bent section of the inner connecting rod 727 become smaller, thereby making the top circle 724 approach the positioning circle 722 until the finger elastic member 70b is balanced with the external force F, and the finger elastic member 70b is no longer compressed; the maximum compression amount of the finger elastic member 70b will be larger, which is suitable for applications in scenarios where the assembly tolerance of connectors and contact discs is large.

[0057] The inclination angle of the inner peripheral surface of the connection hole of the power terminal in this embodiment is consistent with the inclination angle of the outer side surface of the outer connection rod 725 of the contact finger elastic member 70b.

[0058] When the contact finger elastic member 70b is installed to the connection hole of the power terminal, the contact finger elastic member 70b is compressed by squeezing the end of the outer connecting rod 725 of the contact finger elastic member 70b close to the positioning rod 721, so that the contact finger elastic member 70b is contracted toward its axis as a whole. When the maximum outer contour diameter of the positioning ring 722 at the bottom is smaller than the opening diameter of the connection hole of the power terminal, the contact finger elastic member 70b can be installed into the connection hole of the power terminal; then the contact finger elastic member 70b rebounds to the outside of its axis under the action of its own elastic force, and at this time, the outer connecting rod 725 of the contact finger elastic member 70b contacts the inner circumference of the connection hole of the power terminal. Since the inner circumference 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 finger elastic member 70b forms an acute angle with the positioning ring 722 at the bottom, the opening diameter of the connection hole of the power terminal is smaller than the maximum outer contour diameter of the positioning ring 722 at the bottom of the contact finger elastic member 70b, thereby preventing the contact finger elastic member 70b from being separated from the power terminal.

[0059] When removing the contact finger elastic member 70b from the power terminal, the outer connecting rod 725 of the contact finger elastic member 70b is squeezed to make the contact finger elastic member 70b as a whole shrink toward its axis. When the maximum outer contour diameter of the positioning ring 722 at the bottom is smaller than the mouth diameter of the connecting hole of the power terminal, a force is applied to the contact finger elastic member 70b away from the power terminal to remove the contact finger elastic member 70b.
