[0026] Referring to Figure 1 and Figure 2 , Figure 1 The axial schematic diagram of the elastic pin terminal provided in an embodiment of the present application and the control circuit board connected thereto is shown, Figure 2 for Figure 1The top view of the elastic pin terminal and the control circuit board. An embodiment of the present application provides a plug-in end structure, which includes an elastic pin terminal 10 and an insulator (not shown, the same below), and the elastic pin terminal 10 is arranged through the insulator. The elastic pin terminal 10 serves as a conductive medium. When the plug-in end structure is connected with another plug-in end structure (not shown, the same below), the elastic pin terminal 10 is connected with the socket terminal of the other plug-in end structure and is electrically conductive to transmit current or signal and ensure the smoothness of the circuit. The insulator is arranged around the elastic pin terminal 10 to accurately fix the position of the elastic pin terminal 10, ensure the alignment, provide mechanical strength to resist external impact or deformation, block the erosion of external dust, moisture, chemicals and the like to the elastic pin terminal 10, and prolong the service life of the elastic pin terminal 10. When the plug-in end structure includes a plurality of elastic pin terminals 10, the insulator can also block the direct contact between adjacent elastic pin terminals 10, reduce the risk of short circuit or signal interference, and maintain electrical safety.

[0027] Please continue to refer to Figure 1 and Figure 2 An embodiment of the present application provides an elastic pin terminal 10, which has a simple structure and is easy to process and form. The elastic pin terminal 10 includes a first plate 100, a second plate 200 and an arch bridge part 300, the arch bridge part 300 is bent and connected between the first plate 100 and the second plate 200, and the first plate 100 and the second plate 200 are arranged opposite to each other and spaced apart. The first plate 100 includes a first elastic tongue 110, and the second plate 200 includes a second elastic tongue 210. The first elastic tongue 110 and the second elastic tongue 210 are arranged opposite to each other, and at least part of at least one of them is turned outward in a direction away from the other. When the elastic pin terminal 10 is inserted into the socket terminal, the first elastic tongue 110 and the second elastic tongue 210 are used to approach each other and elastically abut the socket terminal under the contraction of the socket terminal.

[0028] In the above-mentioned elastic pin terminal 10, the first plate 100 includes a first elastic tongue 110, the second plate 200 includes a second elastic tongue 210, the arch bridge part 300 is bent and connected between the first plate 100 and the second plate 200, the first plate 100 and the second plate 200 are arranged opposite to each other and spaced apart, and the first elastic tongue 110 of the first plate 100 can be aligned with the second elastic tongue 210 of the second plate 200. Thus, when the elastic pin terminal 10 is inserted into the socket terminal, the first elastic tongue 110 and the second elastic tongue 210 can cooperate with each other to elastically abut the socket terminal, so as to stably contact the socket terminal and be electrically conductive. The elastic pin terminal 10 provided by the present application has a simple structure. After the first elastic tongue 110 is pre-processed on the first plate 100 and the second elastic tongue 210 is pre-processed on the second plate 200, the first plate 100 and the second plate 200 are turned and bent at the arch bridge part 300 to form the elastic pin terminal 10. The processing operation is simple and the processing efficiency is high.

[0029] Referring to Figure 2 In one embodiment, the first elastic tongue 110 and the second elastic tongue 210 can be configured to be everted relative to each other, i.e. the first elastic tongue 110 and the second elastic tongue 210 are everted in a direction away from each other, so as to be deformed and kept in close contact when being plugged into the jack terminal.

[0030] Referring to Figure 1 and Figure 2 In one embodiment, the first plate 100 and the second plate 200 are mirror image structures. That is, the elastic pin terminal 10 has a middle surface PL, the first plate 100 and the second plate 200 are the same distance from the middle surface PL, and the first plate 100 and the second plate 200 are symmetrical about the middle surface PL. That is, before being bent, mirror image processing operations can be applied to the first plate 100 and the second plate 200, and then after being bent around the arch bridge portion 300, the elastic pin terminal 10 as described in each embodiment can be formed.

[0031] In one embodiment, the elastic pin terminal 10 can be configured to be formed by stamping. It can be understood that the first plate 100 and the second plate 200 are both plate structures, so the elastic pin terminal 10 can be stamped and bent from a plate. Before being bent, corresponding structural features (such as the first elastic tongue 110 and the second elastic tongue 210 described above, and the first clamping tongue 130 and the second clamping tongue 230, the first through hole 140 and the second through hole 240, the first limiting portion 150 and the second limiting portion to be mentioned below) can be stamped at the regions corresponding to the first plate 100 and the second plate 200, and then after being bent at the arch bridge portion 300, the elastic pin terminal 10 as described in each embodiment can be obtained.

[0032] Referring to Figure 3 and Figure 4 Further, the two opposite side surfaces of the first plate 100 and the second plate 200 can be smoothly connected with the inner circumferential surface of the arch bridge portion 300; and the two opposite side surfaces of the first plate 100 and the second plate 200 can be smoothly connected with the outer circumferential surface of the arch bridge portion 300. That is, when the elastic pin terminal 10 is in a plate state and the arch bridge portion 300 has not been bent, the arch bridge portion 300 is also part of the overall planar plate, and the arch bridge portion 300 is part of the plate-shaped plate together with the first plate 100 and the second plate 200.

[0033] Referring to Figure 2In one embodiment, the first plate 100 further comprises a first connecting plate 120, and the arch bridge 300 is connected to the first connecting plate 120. The first elastic tongue 110 comprises a first head 111 and a first tongue body 112, and the first tongue body 112 is outwardly turned away from the second plate 200. One end of the first tongue body 112 is connected to the first connecting plate 120, and the other end is connected to the first head 111. The end of the first head 111 away from the first tongue body 112 is inwardly bent towards the side where the second plate 200 is located, and the first head 111 is used to contact the jack terminal first. In this embodiment, the first tongue body 112 mainly forms the outwardly turned shape of the first elastic tongue 110. As the end of the first elastic tongue 110 away from the first connecting plate 120, the first head 111 first contacts the jack terminal, so the end of the first head 111 away from the first tongue body 112 is configured to be inwardly bent, which can facilitate the insertion into the jack terminal and gradually fold the outwardly turned first elastic tongue 110 and second elastic tongue 210 under the action of the jack terminal.

[0034] Please continue to refer to Figure 2 Similarly to the first elastic tongue 110, the second plate 200 further comprises a second connecting plate 220, and the arch bridge 300 is connected to the second connecting plate 220, i.e. the arch bridge 300 is connected between the first connecting plate 120 and the second connecting plate 220. The second elastic tongue 210 comprises a second head 211 and a second tongue body 212, and the second tongue body 212 is outwardly turned away from the first plate 100. One end of the second tongue body 212 is connected to the second connecting plate 220, and the other end is connected to the second head 211. The end of the second head 211 away from the second tongue body 212 is inwardly bent towards the side where the first plate 100 is located, and the second head 211 is used to contact the jack terminal first. Thus, the first head 111 and the second head 211 can cooperate with each other to guide the elastic pin terminal 10 and the jack terminal when they are inserted, facilitating the smooth insertion of the elastic pin terminal 10 and the jack terminal.

[0035] Please continue to refer to Figure 2 In one embodiment, the first head 111 can be configured to be arc-shaped inwardly bent to reduce the resistance during the insertion and cooperation. The second head 211 can also be configured to be arc-shaped inwardly bent to reduce the resistance during the insertion and cooperation.

[0036] Please continue to refer to Figure 2In one embodiment, the first plate 100 further comprises a first root 113, the first root 113 comprising a first end 114 and a second end 115, the first end 114 and the second end 115 being oppositely arranged. The first end 114 is connected with the first connecting plate 120, and the second end 115 is connected with the first tongue 112. The second end 115 is inwardly bent towards the side where the second plate 200 is located relative to the first end 114, so that the second end 115 is closer to the second plate 200. In this way, the distance from the first head 111 to the second plate 200 is reduced, i.e. the opening size at the first elastic tongue 110 is reduced, facilitating the insertion with the jack terminal, under the premise that the first tongue 112 is everted relative to the second plate 200.

[0037] The second plate 200 further comprises a second root 213, the second root 213 comprising a third end 214 and a fourth end 215, the third end 214 and the fourth end 215 being oppositely arranged. The third end 214 is connected with the second connecting plate 220, and the fourth end 215 is connected with the second tongue 212. The fourth end 215 is inwardly bent towards the side where the first plate 100 is located relative to the third end 214, so that the fourth end 215 is closer to the first plate 100. In this way, the distance from the second head 211 to the first plate 100 is reduced, i.e. the opening size at the second elastic tongue 210 is reduced, facilitating the insertion with the jack terminal, under the premise that the second tongue 212 is everted relative to the first plate 100.

[0038] Please refer to Figure 2 In one embodiment, the first plate 100 further comprises a first clamping tongue 130, one end of the first clamping tongue 130 being connected with the first connecting plate 120, and the other end being everted towards the side away from the second plate 200, for abutting against the insulator. When the elastic contact terminal 10 is inserted with the jack terminal, the elastic contact terminal 10 will be subjected to a force directed from the first head 111 to the first root 113, at this time, the end of the first clamping tongue 130 away from the first elastic tongue 110 is everted and abuts against the insulator, which can reduce the risk of loosening and back-off of the elastic contact terminal 10 under the above-mentioned force, and improve the stability of the insertion structure.

[0039] Please refer to Figure 3 In one embodiment, the first connecting plate 120 is provided with a first through hole 140, one end of the first clamping tongue 130 being connected with the hole wall of the first through hole 140, and the other end being everted outside the first through hole 140, so as to abut against the insulator. It is easy to understand that the first through hole 140 can be formed by stamping, and when the first through hole 140 is stamped on the plate, a certain area is reserved to form the first clamping tongue 130 (before being everted) as described in each embodiment.

[0040] In one embodiment, the second plate 200 comprises a second clamping tongue 230, which is connected to the second connecting plate 220 near one end of the second elastic tongue 210 and outwardly flaps towards the side away from the first plate 100 at the other end, for abutting against the insulator. When the elastic contact pin terminal 10 is inserted into the socket terminal, the elastic contact pin terminal 10 will be subjected to a force directed from the second head 211 to the second root 213, at which time the end of the second clamping tongue 230 away from the second elastic tongue 210 flaps outwardly and abuts against the insulator, which can also reduce the risk of the elastic contact pin terminal 10 loosening and retracting under the above-mentioned force and improve the stability of the insertion structure.

[0041] Similarly to the elastic tongue, the first clamping tongue 130 and the second clamping tongue 230 can also be oppositely arranged and outwardly flap in directions away from each other.

[0042] Please refer to Figure 1 and Figure 2 In one embodiment, the second connecting plate 220 is provided with a second through hole 240, one end of the second clamping tongue 230 is connected to the hole wall of the second through hole 240, and the other end flaps outwardly of the second through hole 240 so as to abut against the insulator. It can be easily understood that the second through hole 240 can be formed by stamping, and when the second through hole 240 is stamped on the plate, a certain area is reserved to form the second clamping tongue 230 (before flapping outwardly) as described in each embodiment.

[0043] Please refer to Figure 3 In one embodiment, the part of the first connecting plate 120 near the end face of the first elastic tongue 110 is connected to the first elastic tongue 110, and the other part forms a first positioning portion 121, which is used to abut against the insulator. In combination with Figure 2 It can be easily understood that the first positioning portion 121 is the end face facing the first elastic tongue 110, and the end of the first clamping tongue 130 abutting against the insulator is the end away from the first elastic tongue 110. That is, the end of the first positioning portion 121 abutting against the insulator is oppositely arranged to the end of the first elastic tongue 110 abutting against the insulator, and both abut against the insulator to improve the stability of the position of the elastic contact pin terminal 10 in the insulator in cooperation with each other. It can be understood that when the elastic contact pin terminal 10 is inserted into the insulator, the abutment of the insulator against the first positioning portion 121 can be used as a standard for insertion into position.

[0044] The part of the second connecting plate 220 near the end face of the second elastic tongue 210 is connected to the second elastic tongue 210, and the other part forms a second positioning portion 221, which is used to abut against the insulator. In combination with Figure 2 Similarly to the above, the second positioning portion 221 can also cooperate with the second clamping tongue 230 to improve the stability of the position of the elastic contact pin terminal 10 in the insulator.

[0045] Please refer toFigure 1 and Figure 3 In one embodiment, the first plate 100 further comprises a first limiting portion 150 protruding from the outer surface of the first connecting plate 120, which is used to make the elastic pin terminal 10 and the insulator in interference fit, so as to further improve the stability of the connection between the elastic pin terminal 10 and the insulator. In the direction of the insertion of the elastic pin terminal 10 and the jack terminal, the number of the first limiting portion 150 can be multiple.

[0046] Similarly, the second plate 200 further comprises a second limiting portion (not shown, the same below), which protrudes from the outer surface of the second connecting plate 220, which is used to make the elastic pin terminal 10 and the insulator in interference fit, so as to further improve the stability of the connection between the elastic pin terminal 10 and the insulator. In the direction of the insertion of the elastic pin terminal 10 and the jack terminal, the number of the second limiting portion can be multiple.

[0047] Please refer to Figure 1 and Figure 3 In one embodiment, the number of the first elastic tongue 110 is multiple, and the number of the second elastic tongue 210 is also multiple. The number of the first elastic tongue 110 can be the same as the number of the second elastic tongue 210, and the multiple first elastic tongues 110 and the multiple second elastic tongues 210 can be one-to-one corresponding to each other, so as to jointly cooperate with the insertion of the jack terminal. Of course, in another embodiment, the number of the first elastic tongue 110 can be different from the number of the second elastic tongue 210, for example, one first elastic tongue 110 can correspond to multiple second elastic tongues 210, or one second elastic tongue 210 can correspond to multiple second elastic tongues 210, etc.

[0048] The multiple first elastic tongues 110 can be arranged side by side and spaced apart in the direction perpendicular to the insertion direction of the elastic pin terminal 10 and parallel to the intermediate surface PL. Similarly, the multiple second elastic tongues 210 can be arranged side by side and spaced apart in the direction perpendicular to the insertion direction of the elastic pin terminal 10 and parallel to the intermediate surface PL.

[0049] In one embodiment, the bending of the first plate 100 and the second plate 200 at the arch bridge portion 300 can further form a connecting hole (not shown, the same below), which can be used for connecting with a connecting cable.

[0050] Please refer to Figure 3 and Figure 4 In another embodiment, the elastic pin terminal 10 further comprises a pin 400, and the elastic pin terminal 10 can be directly connected with an electrical element through the pin 400, so as to realize electrical conduction. The number of the pin 400 is multiple, and the first plate 100 and the second plate 200 are both distributed with the above-mentioned pin 400.

[0051] The embodiment of the present application also provides an electronic device, which comprises a control circuit board 20 and the plug-in end structure as described in each embodiment, and the elastic plug-in pin terminal 10 of the plug-in end structure can be directly welded on the control circuit board 20 through the pin 400 to realize installation and electrical conduction.

[0052] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0053] The above embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
