[0037] With the continuous development of modern industry and daily life, connectors have become particularly important due to their wide application in various devices and electrical appliances. As a key interface between devices, connectors are used not only for data transmission but also for power supply, enabling devices to flexibly interconnect in different application scenarios.

[0038] Existing connectors generally include a sleeve, conductive terminals, and a spring. While this design can initially demonstrate good electrical connection performance, the spring that contacts the conductive terminals is prone to elastic fatigue or deformation due to repeated insertion and removal over a long period of time. Elastic fatigue will increase the contact resistance of the connector, affecting its electrical performance and reliability, and thus affecting the service life of the connector.

[0039] This invention proposes a connector to improve the service life of the connector.

[0040] Please refer to 1 to Figure 3 In one embodiment, the connector includes an insulating housing 100 and conductive terminals 200. The insulating housing 100 has a receiving groove 120 and a through hole 110 communicating with the receiving groove 120. The conductive terminals 200 include a mating portion 210 and an elastic portion 220 connected to each other. The elastic portion 220 is disposed in the receiving groove 120. The mating portion 210 includes a bent section 211. The mating portion 210 extends from the through hole 110 and the bent section 211 is exposed in the through hole 110. The elastic portion 220 includes a plurality of first support arms 221 arranged laterally at intervals and a first bending section 222 connecting two adjacent first support arms 221. The bending radii of the plurality of first bending sections 222 are the same. The first support arms 221 and the first bending sections 222 cooperate to allow two adjacent first support arms 221 to move closer to or further away from each other.

[0041] In one embodiment, the insulating housing 100 has multiple independent receiving grooves 120 spaced apart inside, each receiving groove 120 corresponding to a through hole 110, and the axes of all the through holes 110 are located on the same horizontal plane. Of course, in other embodiments, the insulating housing 100 may also have only one receiving groove 120 and one through hole 110, and the number of receiving grooves 120 and through holes 110 is not limited here. In one embodiment, the through hole 110 is configured to be circular to give the insulating housing 100 better versatility and flexibility. Of course, in other embodiments, the through hole 110 may also be configured to be rectangular, polygonal, or irregular in shape, etc., and there is no limitation here. The insulating housing 100 may be made of materials with good insulation and strength, such as polycarbonate, alumina, or polysulfone, and the specific material of the insulating housing 100 is not limited here.

[0042] In one embodiment, multiple conductive terminals 200 are provided, and each conductive terminal 200 corresponds to one of the receiving grooves 120 and through holes 110. Of course, in other embodiments, only one conductive terminal 200 may be provided. The number of conductive terminals 200 is flexibly set according to the number of receiving grooves 120 and actual needs, and is not limited here. In one embodiment, the main body of the conductive terminal 200 is an elastic part 220, which is confined within the receiving groove 120. A mating part 210 is provided at one end of the elastic part 220, and a bent section 211 is provided at the end of the mating part 210 away from the elastic part 220. The bent section 211 is exposed in the through hole 110 to facilitate stable contact with electrical equipment or other conductive components.

[0043] In one embodiment, the elastic portion 220 has multiple first support arms 221 spaced apart, with a first bending segment 222 between each pair of adjacent first support arms 221. Of course, in other embodiments, only two first support arms 221 may be provided, and at least one first bending segment 222 may be provided; this is not a limitation. In one embodiment, all the first bending segments 222 of the elastic portion 220 are staggered on opposite sides of the receiving groove 120, and the first bending segments 222 are configured in an arc shape to give them a high resilience. Further, in one embodiment, the first support arms 221 are inclined, and the inclination directions of adjacent first support arms 221 intersect. The first support arms 221 provide support for the first bending segments 222, and the first bending segments 222 connect adjacent first support arms 221 to form a V-shaped structure, improving the elastic deformation capability and structural stability of the elastic portion 220. In one embodiment, all the first bending segments 222 have the same bending radius to ensure that all the first support arms 221 are evenly distributed in the lateral direction. In the initial state, i.e., when the first bending segment 222 is not deformed, there is an initial distance between two adjacent first support arms 221. The bending radius of the first bending segment 222 can be flexibly set according to actual needs, as long as all the first bending segments 222 have the same bending radius; the initial distance can also be flexibly set according to the bending radius, and no specific restrictions are placed on the bending radius and the initial distance here.

[0044] Thus, when an external force is applied to the mating portion 210, the first bending segment 222 deforms, causing the two adjacent first support arms 221 to move closer or further apart, allowing the mating portion 210 to move along the through hole 110 for docking with equipment or other components. After the external force is removed, the first bending segment 222 springs back to its initial state, causing the two adjacent first support arms 221 to return to their initial distance. Furthermore, by setting all the first bending segments 222 to have the same bending radius, the uniformity of deformation of the elastic portion 220 can be ensured, stress concentration can be avoided, and the overall fatigue resistance of the elastic portion 220 can be improved, thereby increasing the service life of the connector.

[0045] The technical solution of this utility model involves setting an insulating shell 100 and a conductive terminal 200 in the connector. The insulating shell 100 is provided with a receiving groove 120 and a through hole 110 communicating with the receiving groove 120. The conductive terminal 200 includes a mating part 210 and an elastic part 220 connected to each other. The elastic part 220 is provided in the receiving groove 120. The mating part 210 includes a bending section 211. The mating part 210 extends out of the through hole 110 and the bending section 211 is exposed in the through hole 110. The elastic part 220 includes a plurality of first support arms 221 arranged laterally and a first bending section 222 connecting two adjacent first support arms 221. The bending radii of the plurality of first bending sections 222 are the same. The first support arms 221 and the first bending sections 222 cooperate to allow two adjacent first support arms 221 to move closer to or further away from each other. Compared to existing connectors with conductive terminals 200 and springs, the present invention provides a plurality of first support arms 221 and a plurality of first bending segments 222 in the elastic portion 220 of the conductive terminal 200. The first support arms 221 and the first bending segments 222 provide sufficient support and springback for the conductive terminal 200, thereby preventing deformation of the conductive terminal 200 during repeated insertion and removal and improving the service life of the connector.

[0046] Please see Figures 2 to 4 In one embodiment, the elastic portion 220 further includes a second bending segment 224 and a second support arm 223.

[0047] The second bending segment 224 is located on the side of the first bending segment 222 near the through hole 110, and the bending radius of the second bending segment 224 is the same as that of the first bending segment 222. In one embodiment, only one second bending segment 224 is provided. One end of the second bending segment 224 is connected to the mating portion 210 and extends partially into the through hole 110, while the other end of the second bending segment 224 is connected to the first bending segment 222. The bending radius of the second bending segment 224 can be flexibly set according to the bending radius of the first bending segment 222, and is not limited here.

[0048] The second support arm 223 connects the second bent section 224 and the first bent section 222, and the length of the second support arm 223 is less than the length of the first support arm 221. In one embodiment, only one second support arm 223 is provided. The second support arm 223 connects the second bent section 224 and the first bent section 222. The second support arm 223 can move closer to or further away from the first support arm 221 so that the mating part 210 can move along the through hole 110. In one embodiment, the length of the second support arm 223 is adapted to the distance between the through hole 110 and the first bent section 222 near the through hole 110, and the length of the first support arm 221 is adapted to the distance between the two first bent sections 222 located on opposite sides of the receiving groove 120. The through hole 110 is located between the opposite sides of the receiving groove 120. Therefore, the length of the second support arm 223 is less than the length of the first support arm 221 to achieve a reasonable layout of the overall structure of the elastic part 220. The lengths of the first support arm 221 and the second support arm 223 can be flexibly set according to actual needs, and no restrictions are imposed here.

[0049] Thus, when an external force is applied to the docking part 210, the second bending segment 224 first deforms, causing the second support arm 223 to move closer to or away from the first support arm 221, causing the first bending segment 222 to deform, which in turn causes the two adjacent first support arms 221 to move closer to or away from each other, so that the docking part 210 can move along the through hole 110.

[0050] The technical solution of this embodiment of the utility model, by setting a second bending segment 224 and a second support arm 223, allows the mating portion 210 to smoothly transition to the elastic portion 220, reducing the direct stress between the mating portion 210 and the elastic portion 220, and increasing the overall structural stability of the conductive terminal 200. By setting the bending radius of the second bending segment 224 to be the same as that of the first bending segment 222, the uniformity of deformation of the elastic portion 220 can be ensured, stress concentration can be avoided, and the service life of the connector can be further improved.

[0051] Please see Figures 2 to 4 In one embodiment, the insulating housing 100 further includes a first limiting part 121, which is disposed on the inner wall of the receiving groove 120 and near the through hole 110. The first limiting part 121 is used to abut against the first support arm 221 near the docking part 210.

[0052] In one embodiment, the first limiting part 121 is disposed on one side of the through hole 110 and is arranged parallel to the second bent section 224. The first limiting part 121 abuts against the first support arm 221 near the docking part 210 to restrict the movement of the first support arm 221 toward the through hole 110 in the lateral direction, thereby limiting the length of the docking part 210 extending out of the through hole 110. In one embodiment, the inner wall portion of the receiving groove 120 protrudes inward to form the first limiting part 121. Of course, in other embodiments, the first limiting part 121 may also be configured as a limiting block or a limiting rod, etc., and fixed to the inner wall of the receiving groove 120 by means of snap-fit ​​or adhesive to abut against the first support arm 221. Here, no specific limitation is made on the first limiting part 121.

[0053] Further, in one embodiment, the insulating housing 100 also includes a second limiting portion 122. The second limiting portion 122 is disposed on the inner wall of the receiving groove 120 and near the through hole 110. The second limiting portion 122 is used to abut against the second support arm 223 to limit the movement of the second support arm 223 toward the through hole 110 in the lateral direction, and further limit the length of the mating portion 210 extending from the through hole 110. In one embodiment, the first limiting portion 121 and the second limiting portion 122 are located on the same side of the receiving groove 120 and are disposed on opposite sides of the through hole 110 to limit the two ends of the elastic portion 220 respectively. Specifically, in one embodiment, the inner wall portion of the receiving groove 120 extends inward to form the second limiting portion 122. Of course, in other embodiments, the second limiting part 122 may also be configured as a limiting block or a limiting rod, which is fixed to the inner wall of the receiving groove 120 by means of snap-fit ​​or adhesive so as to abut against the second support arm 223. Here, no specific limitation is made on the second limiting part 122.

[0054] The technical solution of this utility model embodiment, by providing a first limiting part 121 and a second limiting part 122, can limit the conductive terminal 200, thereby limiting the length of the mating part 210 exposed in the through hole 110. By providing the first limiting part 121 and the second limiting part 122 on opposite sides of the through hole 110, the elastic part 220 is kept stable at all times, avoiding uneven force and improving the reliability of the connector.

[0055] Please see Figures 2 to 4 In one embodiment, the conductive terminal 200 is integrally formed. The conductive terminal 200 extends from the through hole 110 and folds back to form a docking portion 210. A bent section 211 is formed at the end of the docking portion 210 away from the elastic portion 220. The cross-sectional shape of the bent section 211 is annular.

[0056] In one embodiment, the main body of the conductive terminal 200 is bent to form an elastic portion 220. The bending of the conductive terminal 200 can be achieved through processes such as die casting or stamping, and is not limited here. In one embodiment, one end of the conductive terminal 200 is folded back to form a mating portion 210, and the main bending portion of the folded-back portion forms a bent section 211. The cross-sectional shape of the bent section 211 is annular, facilitating insertion. Of course, in other embodiments, the cross-sectional shape of the bent portion can also be rectangular or polygonal, and is not limited here. The material of the conductive terminal 200 can be copper, copper alloy, nickel, or gold-plated materials with good conductivity and durability, and the specific material of the conductive terminal 200 is not limited here.

[0057] The technical solution of this utility model embodiment simplifies the structure of the conductive terminal 200 by integrally molding the conductive terminal 200, thereby improving the overall stability of the conductive terminal 200. Furthermore, the folding back of one end of the conductive terminal 200 to form the mating portion 210 increases the rigidity of the mating portion 210. By setting the cross-sectional shape of the bent portion to an annular shape, on the one hand, the cross-sectional area of ​​the mating portion 210 can be increased, reducing the resistance of the conductive terminal 200; on the other hand, the surface of the mating portion 210 can be made smoother, facilitating mating and improving the reliability and stability of the connector.

[0058] Please see Figures 2 to 4 In one embodiment, the conductive terminal 200 further includes a support portion 230, and the mating portion 210 further includes a straight segment. The straight segment connects the bent segment 211 and the elastic portion 220. The mating portion 210 extends to both sides and is bent to form the support portion 230. The support portion 230 wraps around the straight segment and corresponds to the through hole 110.

[0059] In one embodiment, the conductive terminal 200 is folded back to form a bent segment 211 and two parallel straight segments. The two straight segments are located on the same side of the bent segment 211. One straight segment extends to both sides and bends to form a support portion 230, which encloses the other straight segment. The other straight segment connects the bent segment 211 and the second bent segment 224. In one embodiment, the support portion 230 is configured as a cylindrical structure, which is fitted around the outer periphery of the other straight segment. The bent segment 211 is exposed outside the support portion 230 to ensure the normal use of the mating portion 210. Further, in one embodiment, the cross-sectional radius of the support portion 230 is smaller than the cross-sectional radius of the through hole 110 to facilitate the movement of the support portion 230 along the through hole 110. In one embodiment, in the initial state, the support portion 230 is partially exposed outside the through hole 110 to provide structural support for the mating portion 210 and guide the movement of the mating portion 210 along the through hole 110. The cross-sectional radii of the support portion 230 and the through hole 110 can be flexibly set according to actual needs, and are not limited here. Of course, in other embodiments, the support portion 230 can also be set as a structure of other shapes to adapt to the through hole 110, and are not limited here. Specifically, in one embodiment, the support portion 230 and the mating portion 210 are integrally formed. Of course, in other embodiments, the support portion 230 can also be set separately, and the straight segments of the support portion 230 and the mating portion 210 are connected to ensure that the support portion 230 and the mating portion 210 can move synchronously along the through hole 110, and the support portion 230 is not limited here.

[0060] The technical solution of this utility model embodiment, by providing the support portion 230, can improve the structural strength of the conductive terminal 200, prevent deformation or damage between the mating portion 210 and the elastic portion 220, ensure that the mating portion 210 can move along the through hole 110, and further improve the service life of the connector. By setting the support portion 230 as a cylindrical structure, on the one hand, it is convenient to guide the mating portion 210 to move along the through hole 110, improving the smoothness of the mating portion 210; on the other hand, it can more evenly distribute stress while strengthening the structure of the conductive terminal 200, and can increase the contact area to reduce resistance, further improving the reliability of the connector.

[0061] Please see Figures 2 to 4 In one embodiment, the conductive terminal 200 further includes a first protrusion 212 disposed on the side of the mating portion 210 away from the elastic portion 220.

[0062] In one embodiment, the first convex bulge 212 serves as the primary contact point of the mating portion 210. The first convex bulge 212 protrudes from the surface of the curved section 211, providing a tighter and more stable connection. In one embodiment, the cross-sectional shape of the first convex bulge 212 is circular to enhance its versatility. In one embodiment, the first convex bulge 212 is integrally formed with the mating portion 210 to ensure connection stability. In one embodiment, each mating portion 210 corresponds to one first convex bulge 212, which is located on the side of the curved section 211 facing away from the elastic portion 220, facilitating direct contact with equipment or other components. Of course, in other embodiments, multiple first convex bulges 212 may be provided; the number of first convex bulges 212 is not limited here.

[0063] The technical solution of this utility model embodiment, by providing a first protrusion 212 on the mating part 210, can improve the contact stability of the mating part 210, and can guide the current to be reasonably distributed, thereby improving the current carrying capacity of the conductive terminal 200 and thus improving the reliability of the connector.

[0064] Please see Figure 3 and Figure 4 In one embodiment, the conductive terminal 200 further includes a welding portion 240. The insulating housing 100 has an opening that communicates with the receiving groove 120. The opening is disposed opposite to the through hole 110. The welding portion 240 is disposed on the side of the elastic portion 220 near the opening and extends out from the opening.

[0065] In one embodiment, the conductive terminal 200 is assembled into the receiving groove 120 through an opening, which is simple to operate; and the opening is always open to facilitate heat dissipation. In one embodiment, the conductive terminal 200 is integrally formed with a welding part 240, which is connected to the first support arm 221 near the opening. In one embodiment, the welding part 240 is configured as a plane and is located on the same horizontal plane as the axis of the through hole 110 to provide a more stable electrical contact surface, which facilitates welding and assembly. Specifically, in one embodiment, the connection between the welding part 240 and the first support arm 221 is an arc surface to reduce connection stress. In one embodiment, the inner wall of the opening is provided with a groove 130, and the welding part 240 is correspondingly provided with a snap-fit ​​part 241. The side of the snap-fit ​​part 241 is provided with a second protrusion 242. The snap-fit ​​part 241 snaps into the groove 130 to limit the conductive terminal 200 in the receiving groove 120, and the second protrusion 242 is used to abut against the groove wall of the groove 130. Specifically, in one embodiment, a second protrusion 242 is provided on each side of the snap-fit ​​portion 241 to ensure that the conductive terminal 200 remains stable. Of course, in other embodiments, multiple second protrusions 242 may be provided; or, they may be provided only at one end of the snap-fit ​​portion 241, without limitation. Of course, in other embodiments, a protrusion may be provided on the inner wall of the opening, and a snap-fit ​​member may be provided on the welding portion 240; or, the welding portion 240 may be directly connected to the inner wall of the opening by welding or bonding, without limitation.
