Description

Technical Field

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

[0002] A connector is an electromechanical component that connects a conductor (wire) to an appropriate matching component to achieve circuit connection and disconnection. Because its application makes the design and production process more convenient and flexible, and reduces production and maintenance costs, connectors are widely used in all walks of life.

[0003] Most existing connectors have inner and outer springs that are arranged at intervals and gradually bend inward from both ends to form a contact portion in the middle, so that the contact parts of the two are on the same virtual circumference, and then the two overlapping springs are placed in the socket body, so as to increase the number of contacts when the socket is matched with the pin and achieve the purpose of current expansion. However, this structure not only takes up space, but also has a small number of contact points for a single contact spring, a small contact cross-sectional area, a large contact resistance, and poor contact reliability.

[0004] The above contents are only used to assist in understanding the technical solution of the invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0005] The main purpose of the present invention is to provide a high current connector, aiming to solve the technical problems of the existing connector having a small contact cross-sectional area, resulting in low current carrying capacity and poor contact reliability.

[0006] To achieve the above-mentioned purpose, the high current connector proposed by the present invention is:

[0010] In one embodiment, the fisheye terminal includes a plurality of elastic parts, each of which has a fisheye hole formed therein, and the plurality of elastic parts are connected end to end and are circumferentially arranged in the cylinder of the female end.

[0011] In one embodiment, the elastic portion includes a first sub-elastic portion and a second sub-elastic portion, the first sub-elastic portion is connected to the second sub-elastic portion at two ends, and the first sub-elastic portion and the second sub-elastic portion enclose the fisheye hole.

[0012] In one embodiment, the outer periphery of the fisheye terminal is concave-convex, and a first protrusion is provided on a side of the first sub-elastic portion close to the inner wall of the cylinder, and the first protrusion abuts against the inner wall of the cylinder.

[0013] In one embodiment, the inner periphery of the fisheye terminal is concave-convex, and a second protrusion is provided on a side of the second sub-elastic portion away from the inner wall of the cylinder, and the second protrusion abuts against the male end.

[0014] In one embodiment, an annular positioning groove is provided on the inner wall surface of the cylinder, and the fisheye terminal is embedded in the positioning groove.

[0015] In one embodiment, the high current connector further includes a connecting ring, and the connecting ring is embedded in the positioning groove.

[0016] In one embodiment, the connecting ring is provided in plurality, the connecting rings are spaced apart in the positioning groove, and the fisheye terminals are staggeredly disposed at the spaced apart positions.

[0017] In one embodiment, the fisheye terminal is arranged in a C-shape or a circle.

[0018] In one embodiment, the material of the fisheye terminal is selected from any one of copper, silver, aluminum, titanium, nickel, zinc, iron, chromium and stainless steel.

[0019] The high current connector of the present invention comprises a male end, a female end and a fisheye terminal, wherein the female end comprises a cylinder, wherein the cylinder has an open end for connecting with the male end, and the open end is for plugging the male end; the fisheye terminal is arranged in the cylinder, the outer periphery of the fisheye terminal abuts against the inner wall of the cylinder, the inner periphery of the fisheye terminal elastically abuts against the male end, and the fisheye terminal can be elastically deformed along the radial direction of the cylinder. In this way, by setting the high current connector as a separate connection, the female end is plugged with the male end, thereby accelerating the plugging and unplugging speed of the high current connector and improving the work efficiency. The fisheye terminal is connected between the male end and the female end, and since the inner periphery of the fisheye terminal elastically abuts against the male end, the fitting ability between the fisheye terminal and the plug-in end is enhanced, so that the contact area between the outer periphery of the plug-in end and the inner wall of the cylinder is increased, thereby improving the current carrying capacity of the high current connector. At the same time, when the plug-in end of the male end is inserted into the barrel, the outer periphery of the plug-in end will abut against the inner periphery of the fisheye terminal, so that the fisheye terminal will undergo elastic deformation along the radial direction of the barrel. After the external force of the plug-in is removed, the fisheye terminal will give the plug-in end a certain reverse elastic pre-tightening force, thereby further enhancing the connection stability of the high-current connector.

[0044] The invention provides a high current connector.

[0045] In the embodiment of the present invention, Figures 1 to 6 As shown, the high current connector 10 includes a male end 11, a female end 12 and a fisheye terminal 13, the female end 12 includes a cylinder 122, the cylinder 122 has an open end 122a for connecting with the male end 11, and the open end 122a is for the male end 11 to be plugged in; the fisheye terminal 13 is arranged in the cylinder 122, the outer periphery of the fisheye terminal 13 abuts against the inner wall surface of the cylinder 122, the inner periphery of the fisheye terminal 13 elastically abuts against the male end 11, and the fisheye terminal 13 can undergo elastic deformation along the radial direction of the cylinder 122.

[0046] Specifically, in the embodiments of the present invention, Fig.15 As shown, the high current connector 10 includes a male end 11, and the male end 11 includes a plug end 112 and a first cable connector 111, and the plug end 112 and the first cable connector 111 are arranged at opposite ends of the male end 11. The plug end 112 is used to cooperate with the female end 12 to achieve electrical signal communication. The first cable connector 111 is roughly cylindrical, so it is convenient to connect and fix the cable, thereby improving the connection stability between the first cable connector 111 and the cable, and at the same time, it can effectively protect the connection to prevent the connection from being exposed, thereby improving the safety of the high current connector 10. The cable can be fixedly connected to the first cable connector 111 by welding or crimping. The male end 11 can be integrally stamped or assembled by a conductive metal material. The conductive metal material can be selected according to different needs and is not limited here.

[0047] Of course, according to needs, after the male terminal 11 is integrally formed, the outer layer of the male terminal 11 can be coated with rubber to form an insulating rubber coating layer, and the insulating rubber coating layer insulates the outer layer of the male terminal 11 to increase the safety of the high-current connector 10.

[0048] like Fig.16 As shown, the high-current connector 10 further includes a female end 12, one end of which is provided with a barrel 122, and one end of the barrel 122 is provided with an open end 122a, and the open end 122a is provided for the plug-in end 112 of the male end 11 to be plugged in, so as to achieve the connection between the male end 11 and the female end 12. The cross-sectional shape of the barrel 122 can be set according to the cross-sectional shape of the plug-in end 112 of the male end 11, and the cross-sectional shape of the plug-in end 112 of the male end 11 can be set as needed, such as being set to a circular, square, triangular or special shape, etc., which is not limited here, and a circular shape is preferably used for explanation in the embodiment of the present invention.

[0049] Of course, the female end 12 is provided with a second cable connector 121, and the cable can be fixedly connected to the second cable connector 121 by welding or crimping. The barrel 122 and the second cable connector 121 are arranged at opposite ends of the female end 12. The second cable connector 121 is generally cylindrical, so that the cable can be conveniently connected and fixed, thereby improving the connection stability between the second cable connector 121 and the cable, and at the same time, the connection can be effectively protected to prevent the connection from being exposed, thereby improving the safety of the high-current connector 10.

[0050] In the embodiment of the present invention, Figure 2 As shown, the high current connector 10 also includes a fisheye terminal 13, which is arranged in the barrel 122 of the female end 12 and arranged along the axial direction of the barrel 122. The fisheye terminal 13 is roughly annular, and of course the fisheye terminal 13 can also be set in other shapes, such as a ring 14, a triangle or a C shape. The shape of the fisheye terminal 13 can be set according to the cross-sectional shape of the inner cavity of the barrel 122, and is not specifically limited here. The high current connector 10 may include a plurality of fisheye terminals 13, and the number of the fisheye terminals 13 can be set as needed. The fisheye terminal 13 and the barrel 122 are roughly coaxially arranged, which can facilitate the plugging of the high current connection. Of course, in other embodiments, the fisheye terminal 13 and the barrel 122 can also be arranged in other forms, which are not specifically limited here. In the present application, in order to ensure the electrical conductivity and elastic recovery ability of the fisheye terminal 13, the fisheye terminal 13 can be stamped or forged from a highly conductive and highly elastic metal material.

[0051] In the embodiment of the present invention, it can be understood that the high current connection has a connection state, that is, the male end 11 and the female end 12 are in a conducting state, such as Figures 3 to 6 and Fig.12 As shown, the male end 11 and the inner periphery of the fisheye terminal 13 are arranged in an interference fit, and after the plug end 112 of the male end 11 is inserted into the barrel 122 of the female end 12, the plug end 112 squeezes the fisheye terminal 13, so that the fisheye terminal 13 is elastically deformed along the radial direction of the barrel 122, so that the outer periphery of the fisheye terminal 13 is in full contact with the inner wall of the barrel 122, and at the same time, the inner periphery of the fisheye terminal 13 can also be in full contact with the plug end 112. When the external force is removed, the fisheye terminal 13 will generate a deformation recovery force due to the deformation, and the deformation recovery force acts on the inner wall surface of the plug end 112 and the barrel 122, so that the male end 11 is locked in the barrel 122 of the female end 12. When the plug end 112 is pulled out of the barrel 122, the fisheye terminal 13 can be restored to its original state by the deformation recovery force. Figures 8 to 11 and Fig.13 shown.

[0052] The high-current connector 10 of the present invention includes a male end 11, a female end 12 and a fisheye terminal 13. The female end 12 includes a barrel 122, and the barrel 122 has an open end 122a for connecting with the male end 11. The open end 122a is plugged into the male end 11. The fisheye terminal 13 is arranged in the barrel 122, and the outer periphery of the fisheye terminal 13 abuts against the inner wall surface of the barrel 122, and the inner periphery of the fisheye terminal 13 elastically abuts against the male end 11. The fisheye terminal 13 can be elastically deformed along the radial direction of the barrel 122. In this way, by setting the high-current connector 10 to a separate connection, the female end 12 is plugged into the male end 11, thereby accelerating the plugging and unplugging speed of the high-current connector 10 and improving work efficiency. The fisheye terminal 13 is connected between the male end 11 and the female end 12. Since the inner periphery of the fisheye terminal 13 is elastically abutted against the male end 11, the fitting ability between the fisheye terminal 13 and the plug end 112 is enhanced, so that the contact area between the outer periphery of the plug end 112 and the inner wall surface of the cylinder 122 is increased, thereby improving the current carrying capacity of the high-current connector 10. At the same time, when the plug end 112 of the male end 11 is inserted into the cylinder 122, the outer periphery of the plug end 112 will abut against the inner periphery of the fisheye terminal 13, so that the fisheye terminal 13 is elastically deformed along the radial direction of the cylinder 122. After the external force of plugging is removed, the fisheye terminal 13 will give the plug end 112 a certain reverse elastic pre-tightening force, thereby further enhancing the connection stability of the high-current connector 10.

[0053] like Fig.12 and Fig.13 As shown, in one embodiment, the fisheye terminal 13 includes a plurality of elastic parts 131, and a fisheye hole 132 is formed in the elastic part 131. The plurality of elastic parts 131 are connected end to end and are arranged in the cylinder 122 of the female end 12. It can be understood that in order to enhance the elastic deformation ability of the fisheye terminal 13, the fisheye terminal 13 may include a plurality of elastic parts 131, and the plurality of elastic parts 131 may be connected in the first position or arranged at intervals, which is not specifically limited here, and may be arranged according to elastic requirements and process requirements. In order to make the elastic part 131 have good elastic deformation ability and deformation recovery force, the elastic part 131 may be hollow, and the fisheye hole 132 is formed in the elastic part 131 in the present application. Of course, in other embodiments, other hollow settings may also be used, which is not specifically limited here.

[0054] Specifically, Figure 12 to Figure 13 As shown, the elastic part 131 includes a first sub-elastic part 131a and a second sub-elastic part 131b, the first sub-elastic part 131a and the second sub-elastic part 131b are connected at both ends, and the first sub-elastic part 131a and the second sub-elastic part 131b enclose the fisheye hole 132. As can be seen from the figure, the first sub-elastic part 131a is arranged on a side of the elastic part 131 close to the inner wall of the cylinder 122, and abuts against the inner wall of the cylinder 122, and the second sub-elastic part 131b is arranged on a side of the elastic part 131 close to the male end 11, and abuts against the male end 11 when connected. The two ends of the first sub-elastic portion 131a are connected to the corresponding two ends of the second sub-elastic portion 131b. The first sub-elastic portion 131a and the second sub-elastic portion 131b are both arranged in an arc shape. The first sub-elastic portion 131a is protruded on the side facing the inner wall surface of the cylinder 122, and the second sub-elastic portion 131b is protruded on the side facing the male end 11, so that the first sub-elastic portion 131a and the second sub-elastic portion 131b enclose a fisheye hole 132.

[0055] like Fig.12 and Fig.13As shown, in some embodiments, the outer periphery of the fisheye terminal 13 is concave-convex, and the first sub-elastic portion 131a is provided with a first protrusion 133 on one side close to the inner wall surface of the cylinder 122, and the first protrusion 133 abuts against the inner wall surface of the cylinder 122. It can be understood that in order to increase the elastic deformation capacity of the fisheye terminal 13, the outer periphery of the fisheye terminal 13 can be set to a concave-convex shape, so that when the plug end 112 of the fisheye terminal 13 is inserted into the cylinder 122, the internal stress of the fisheye terminal 13 is reduced, so that the fisheye terminal 13 can have a better deformation capacity, so that the fisheye terminal 13 and the inner wall surface of the cylinder 122 are more closely attached, and the contact area between each other is increased, thereby enhancing the current carrying capacity of the high-current connector 10. Furthermore, in order to improve the connection stability between the fisheye terminal 13 and the inner wall surface of the cylinder 122, in the present application, the first sub-elastic portion 131a is provided with a first protrusion 133 on the side close to the inner wall surface of the cylinder 122, and the first protrusion 133 abuts against the inner wall surface of the cylinder 122. The first protrusion 133 is used to replace the outer periphery of the fisheye terminal 13 to abut against the inner wall surface of the cylinder 122, from surface-to-surface contact to surface-to-point contact, thereby enhancing the connection reliability of the high-current connector 10. At the same time, by providing a plurality of the first protrusions 133 on the outer periphery of the fisheye terminal 13, the contact area between the fisheye terminal 13 and the inner wall surface of the cylinder 122 can be increased, thereby enhancing the current carrying capacity of the high-current connector 10.

[0056] like Fig.12 and Fig.13As shown, in some embodiments, the inner periphery of the fisheye terminal 13 is concave-convex, and a second protrusion 134 is provided on the side of the second sub-elastic portion 131b away from the inner wall of the barrel 122, and the second protrusion 134 abuts against the male end 11. It can be understood that in order to increase the elastic deformation capacity of the fisheye terminal 13, the inner periphery of the fisheye terminal 13 can be set to a concave-convex shape, so that when the plug end 112 of the fisheye terminal 13 is inserted into the barrel 122, the internal stress of the fisheye terminal 13 is reduced, so that the fisheye terminal 13 can have a better deformation capacity, so that the fisheye terminal 13 and the male end 11 are more closely fitted, and the contact area between each other is increased, thereby enhancing the current carrying capacity of the high-current connector 10. Furthermore, in order to improve the connection stability between the fisheye terminal 13 and the male end 11, in the present application, the second sub-elastic portion 131b is provided with a second protrusion 134 on the side away from the inner wall surface of the cylinder 122, and the second protrusion 134 abuts against the male end 11. The second protrusion 134 is used to replace the inner periphery of the fisheye terminal 13 to abut against the male end 11, from surface-to-surface contact to surface-to-point contact, so as to enhance the connection reliability of the high-current connector 10. At the same time, by providing a plurality of the second protrusions 134 on the inner periphery of the fisheye terminal 13, the contact area between the fisheye terminal 13 and the male end 11 can be increased, thereby enhancing the current carrying capacity of the high-current connector 10.

[0057] like Figure 5 and Fig.10 As shown, in one embodiment, an annular positioning groove 122b is provided on the inner wall surface of the cylinder 122, and the fisheye terminal 13 is embedded in the positioning groove 122b. It can be understood that since the fisheye terminal 13 is arranged along the axial direction of the cylinder 122, and the fisheye terminal 13 abuts against the inner wall surface of the cylinder 122 through interference fit, in order to facilitate the fixing of the fisheye terminal 13 in the axial direction, an annular positioning groove 122b can be provided on the inner wall surface of the cylinder 122, and then the fisheye terminal 13 is embedded in the positioning groove 122b, so that the fisheye terminal 13 can be fixed. Of course, in other embodiments, the fisheye terminal 13 can also be fixed in the cylinder 122 by other methods, such as welding, bonding, etc., which are not particularly limited here. In the present application, the positioning groove 122b is provided, and the fisheye terminal 13 is embedded in the positioning groove 122b. Compared with directly bonding or welding the fisheye terminal 13 to the inner wall surface of the cylinder 122, the fisheye terminal 13 can have better elastic deformation ability with the male end 11 or the female end 12 when plugged in.

[0058] like Figures 4 to 5As shown, in one embodiment, the high current connector 10 further includes a connecting ring 14, which is embedded in the positioning groove 122b. It can be understood that in order to increase the applicability of the high current connector 10, that is, to cope with different current carrying capacity and connection stability requirements, the number of the fisheye terminals 13 in the high current connector 10 can be conveniently adjusted, so that the connecting ring 14 is set in the positioning groove. At the same time, the connecting ring 14 abuts against the fisheye terminal 13 and the inner wall of the cylinder 122 through the end faces on both sides, thereby increasing the contact area and also increasing the current carrying capacity of the high current connector 10.

[0059] Furthermore, if Figure 2 and Figure 5 As shown, the connecting ring 14 is set to be multiple, and the multiple connecting rings 14 are arranged at intervals in the positioning groove 122b, and the multiple fisheye terminals 13 are staggered at the intervals. It can be understood that in some embodiments, in order to increase the current carrying capacity of the connection between the male end 11 and the female end 12, a plating layer can be set on the outer peripheral side of the plug end 112 to reduce the resistance at the connection, thereby improving the current carrying capacity of the high current connector 10. In order to reduce the electroplating cost or adapt to different male ends 11. In the present application, the connecting ring 14 can be set to be multiple, and the multiple connecting rings 14 can be set according to the setting form of the plating layer, so that the fisheye terminal 13 can be fully utilized to contact the plating layer on the male end 11, improve the utilization rate between the fisheye terminal 13 and the plating layer, and save costs. It should be noted that the number of the fisheye terminals 13 set at the interval between two adjacent connecting rings 14 can be set as needed, and no special limitation is made here.

[0060] like Fig.13 and Fig.14 As shown, in one embodiment, the fisheye terminal 13 is C-shaped or circular. It can be understood that since the fisheye terminal 13 is arranged in the cylinder 122 of the female end 12, and the outer periphery of the fisheye terminal 13 abuts against the inner wall surface of the cylinder 122, the inner periphery of the fisheye terminal 13 elastically abuts against the male end 11, so that the fisheye terminal 13 can be fully in contact with the female end 12 and the male end 11, thereby increasing the current carrying capacity and connection stability. The shape of the outer periphery and the shape of the inner periphery of the fisheye terminal 13 can be set according to the shape of the contact surface with the female end 12 and the male end 11, and no special limitation is made here. In this application, setting the fisheye terminal 13 to be C-shaped or circular is only an example and is not a limitation of the present invention. For example, in other embodiments, the fisheye terminal 13 can be set to be triangular or irregular.

[0061] Optionally, the material of the fisheye terminal 13 is selected from any one of copper, silver, aluminum, titanium, nickel, zinc, iron, chromium and stainless steel. That is, the fisheye terminal 13 can be stamped or forged from copper, silver, aluminum, titanium, nickel, zinc, iron, stainless steel or alloys thereof. Among them, the alloy material can be beryllium copper alloy, copper-nickel alloy, copper-nickel-silicon alloy or nickel-copper-chromium alloy, etc. A comprehensive selection can be made based on the required current carrying capacity and elastic deformation capacity, which is not particularly limited here.

[0062] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
