DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1, a contact member capable of realizing multi-layer contact, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a contact member capable of realizing multi-layer contact comprises a welding portion 1, a connection portion and a spring portion, wherein the connection portion comprises a first connection portion 2 and a second connection portion 3, and the spring portion comprises a first spring group 4 and a second spring group 5, wherein the second spring group 5 and the second connection portion 3 are integrally connected to the welding portion 1, and the second spring group 5 is arranged on the upper and lower sides of the second connection portion 3, respectively, and the two ends of the first connection portion 2 are integrally connected to the left and right sides of the second connection portion 3, respectively, and the first connection portion 2 is integrally connected to the first spring group 4. The second spring group 5 is arranged on the upper and lower sides of the second connection portion 3, and the first spring group 4 is arranged on the left and right sides of the second connection portion 3 through the first connection portion 2. When the width of the second connection portion 3 is not increased, the number of cantilevers is increased by adding the first spring group 4 indirectly connected to the left and right sides of the second connection portion 3 through the first connection portion 2, thereby increasing the number of contact points, and effectively improving the flow capacity, so that the number of contact points can meet the required flow capacity, and solves the technical problem that the number of contact points cannot meet the required flow capacity in the prior art when only contact points are added on the upper and lower sides of the connection portion.

[0032] Embodiment 2, based on embodiment 1, a contact member capable of realizing multi-layer contact, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first reed group 4 and the second reed group 5 are coaxially arranged, and in the direction of insertion of the connector 6, the second reed group 5 and the first reed group 4 are located at different height layers on the same side of the connector 6. Dividing the second reed group 5 and the first reed group 4 into two layers of different height layers can effectively reduce the insertion resistance when the connector 6 is inserted.

[0033] Embodiment 3, based on embodiment 2, a contact member capable of realizing multi-layer contact, such as Figure 3 and Figure 4 As shown, the first spring group 4 and the second spring group 5 both include cantilevers, and the cantilevers are both provided with a bending section 7. The cantilever of the first spring group 4 is integrally connected to the first connecting portion 2, and the cantilever of the second spring group 5 is integrally connected to the second connecting portion 3. The setting of the bending section 7, on the one hand, enables the positions where the first spring group 4 and the second spring group 5 contact with the end of the plug-in connector 6 to form a contact arc surface, which can effectively reduce the insertion resistance. On the other hand, the bending section 7 is used to achieve a certain flexibility in the contact position between the spring and the plug-in connector 6, thereby improving compatibility and having a good tolerance capability.

[0034] Embodiment 4, based on embodiment 3, a contact member capable of realizing multi-layer contact, such as Figure 1 and Figure 3 As shown, the convex points of the bending section 7 on the first spring group 4 are all on the first height plane, and the convex points of the bending section 7 on the second spring group 5 are all on the second height plane, and the first height plane is above the second height plane; on the same side of the insertion direction, the convex points of the bending section 7 on the second spring group 5 and the convex points of the bending section 7 on the first spring group 4 are located on the same plane. The contact has two layers of convex points on the upper and lower sides to contact the plug-in connector 6, which improves the tolerance capacity and connection reliability, and is not easy to deviate after the plug-in connector 6 is inserted, thereby improving the vibration resistance and mechanical impact performance. At the same time, on the same side of the insertion direction, the convex points of the bending section 7 on the second spring group 5 and the convex points of the bending section 7 on the first spring group 4 are located on the same plane, which avoids the situation where the convex points hinder the insertion of the plug-in connector 6 when the plug-in connector 6 is inserted.

[0035] Embodiment 5, based on embodiment 4, a contact member capable of realizing multi-layer contact, such as Figure 1 and Figure 4As shown, the two ends of the first connection part 2 are bent and connected to the left and right sides of the second connection part 3 as a whole; a feed hole 11 is provided at the bend of the first connection part 2. The first connection part 2 is connected to the first spring group 4, wherein the first connection part 2 is bent and connected to the second connection part 3, and the feed hole 11 is provided at the connection, so that the first connection part 2 has a certain flexibility, which can effectively reduce the pressure on the contact when the plug-in part 6 is inserted, improve the vibration resistance of the contact, and have a good floating ability.

[0036] Embodiment 6, based on embodiment 5, a contact member capable of realizing multi-layer contact, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first connection part 2 is located above the second connection part 3, and the first connection part 2 is provided with a through hole 12 for the second reed group 5 to pass through. The through hole 12 is provided to allow the second reed group 5 to pass through the first connection part 2 and extend below the first reed group 4.

[0037] When implementing Example 6, a sample of the contact piece is punched out, wherein the first reed group 4 and the second reed group 5 are bent after forming to form a bending section 7, then the first reed group 4 is bent into shape, then the welding portion 1 is bent, then the second reed group 5 is bent into shape, then the first connecting portion 2 and the second connecting portion 3 are bent into a certain angle, then the first connecting portion 2 is bent and the second reed group 5 is passed through the through hole 12 on the first connecting portion 2, wherein the bending sections 7 of the first reed group 4 and the second reed group 5 are located at different height levels on one side, and the contact piece of the present application can be obtained.

[0038] Embodiment 7, based on any one of embodiments 1 to 6, a plug connector for the above-mentioned contact member, such as Figure 5 , Figure 6 and Figure 7 As shown, it includes a plug body 8 that can be plugged with the first spring group 4 and the second spring group 5. The plug body 8 is provided to be plugged and connected with the first spring group 4 and the second spring group 5 on the contact piece. The plug head of the plug body 8 is provided with a chamfer to facilitate the insertion of the plug body 8, which can effectively reduce the difficulty of inserting the plug body 8.

[0039] Embodiment 8, based on embodiment 7, a plug connector for the above-mentioned contact member, such as Figure 5 , Figure 6 and Figure 7 As shown, the plug body 8 is provided with a folding wing structure 10 that can cooperate with the first spring group 4. The folding wing structure 10 is provided to cooperate with both sides of the spring part to play a limiting role, limit the movement of the plug connector 6 during vibration, and improve the connection stability between the plug connector 6 and the contact.

[0040] Among them, two folding wing structures 10 are connected to the upper part of the plug-in body 8. Preferably, the two folding wing structures 10 are formed by bending in opposite directions. Such arrangement enables the two folding wing structures 10 to respectively cooperate with the two oppositely arranged bending sections 7 on the first spring leaf group 4, which is beneficial to the uniform force of the two groups of springs on the first spring leaf group 4 and to ensure the connection stability between the plug-in component 6 and the contact member. The distance between the folding wing structure 10 and the head of the plug-in body 8 is A. When the plug-in body 8 is plugged and matched with the first spring leaf group 4 and the second spring leaf group 5 in the insertion direction, the folding wing structure 10 cooperates with the side of the bending section 7 of the first spring leaf group 4. The side cooperation of the folding wing structure 10 and the bending section 7 is to further reduce the length of the folding wing structure 10. On the basis of ensuring the limiting effect of the folding wing structure 10 on the plug-in component 6, the material required to form the folding wing structure 10 can be further reduced.

[0041] Embodiment 9, based on embodiment 8, a plug connector for the above-mentioned contact member, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the plug body 8 is provided with a floating structure 9 which cooperates with the upper bending section 7 of the first spring group 4. The floating structure 9 is provided to limit the insertion of the plug connector 6, and at the same time increase the number of contact points between the plug connector 6 and the outer convex points of the upper bending section 7 of the first spring group 4, thereby reducing the contact resistance.

[0042] The floating structure 9 includes two groups of stopping units provided on one side of the plug-in body 8, and the floating structures 9 are symmetrically arranged on the two sides of the plug-in body 8. When the plug-in component 6 is inserted, the outer convex point of the bent section 7 on the first spring group 4 is located between the two groups of stopping units. The floating structure 9 prevents the plug-in component 6 from being separated from the first spring group 4 after insertion, and prevents the plug-in component 6 from being further inserted into the plug-in component 6 after insertion.

[0043] The stopping unit may be composed of a plurality of convex bumps 13. When the connector 6 is inserted, the outer convex point of the bending section 7 on the first spring group 4 is located between the two groups of convex bumps 13. The floating structure 9 prevents the connector 6 from being separated from the first spring group 4 after insertion, and prevents the connector 6 from being further inserted into the first spring group 4 after insertion.

[0044] The stopper unit may also be composed of a convex bump 13 and a concave groove 14, such as Figure 5As shown, along the horizontal direction of the plug body 8, a groove 14 is provided between two adjacent convex bumps 13, and along the vertical direction of the plug body 8, the convex bump 13 and the groove 14 are arranged adjacent to each other, and along the vertical direction of the plug body 8 is the insertion reverse direction of the plug connector 6. After the plug connector 6 is inserted, the outer convex point of the bending section 7 on the first spring leaf group 4 is located between the convex bump 13 and the groove 14, and the floating structure 9 not only prevents the plug connector 6 from being separated from the first spring leaf group 4 after insertion, but also prevents the plug connector 6 from being further inserted into the plug connector 6 after insertion.

[0045] When implementing Example 9, a template of the connector 6 is directly punched out, and the arrangement of the protrusions 13 and the grooves 14 on the connector 6 can be selected as needed and is not limited here. Then, the folding wing structures 10 on the template are bent toward each other to obtain the connector 6 of the present application.

[0046] Embodiment 10, based on any one of embodiments 1 to 9, a plug-in mechanism, such as Figure 8 As shown, it includes the above-mentioned contact piece and the above-mentioned connector. When the connector 6 is inserted, the connector 6 is respectively connected with the first spring group 4 and the second spring group 5, the folding wing structure 10 is matched with the side stop of the bending section 7 of the first spring group 4, and the floating structure 9 is matched with the outer convex point of the bending section 7 on the first spring group 4.

[0047] When Example 10 is implemented, the connector 6 is inserted into the contact piece. At this time, the connector 6 is respectively connected with the first spring group 4 and the second spring group 5. The folding wing structure 10 is matched with the side stop of the bending section 7 of the first spring group 4. The floating structure 9 is matched with the outer convex point of the bending section 7 of the first spring group 4. The outer convex point of the bending section 7 of the first spring group 4 is located between the convex bump 13 and the groove 14. The floating structure 9 not only prevents the connector 6 from being separated from the first spring group 4 after insertion, but also prevents the connector 6 from being further inserted into the connector 6 after insertion, thereby forming the plug-in mechanism of the present application.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
