Multi-support fatigue-resistant terminal connector

Abstract

The invention provides a multi-support fatigue-resistant terminal connector, and belongs to the technical field of terminal connection. Comprising a supporting arm for providing auxiliary support for an arc-shaped elastic arm, the supporting arm is used for applying lifting force for the arc-shaped elastic arm to get close to a male end terminal, the supporting arm is integrally constructed on the arc-shaped elastic arm, and the supporting arm abuts against the bottom of the arc-shaped elastic arm after being bent into an arc shape. The arc-shaped elastic arm has an elastic reset effect and also has auxiliary reset of the supporting arm, so that the elastic reset effect is improved. The supporting arm is constructed to be in a C-shaped arc shape, meanwhile, the arc-shaped end of the supporting arm supports the arc-shaped elastic arm and is opposite to the arc-shaped elastic arm, and in order to prevent the situation that the recovery effect becomes poor due to excessive deformation of the arc-shaped section of the supporting arm, the first limiting arm used for abutting against the arc-shaped section of the supporting arm is further constructed on the female end.

Description

Technical Field

[0001] The invention relates to the technical field of terminal connection, in particular to a multi-support fatigue-resistant terminal connector. Background Art

[0002] Terminal connectors are electronic components that are mainly used to connect two circuits or electronic devices to transmit electrical signals or power. They are usually used for connections between or within circuit boards, wires, and electronic devices.

[0003] The terminal connector of the prior art mainly includes three parts: a male terminal; a female terminal; and an arc-shaped elastic arm. The male terminal is a sheet-shaped metal sheet, which is inserted into the female terminal and fits with the arc-shaped elastic arm in the female terminal, thereby realizing conduction between the male terminal and the female terminal, wherein the metal sheet of the male terminal is inserted into the female terminal, and the arc-shaped elastic arm of the female end is deformed to clamp the metal sheet of the male terminal to realize the contact and connection between the two. This structure can indeed realize a relatively simple and reasonable connection, but in practice, since the male and female terminals need to meet multiple plugging and unplugging, the arc-shaped elastic arm of the female end will undergo plastic deformation after being squeezed for multiple and long periods of time, and cannot return to its original height (simply put, elastic fatigue), which leads to poor contact problems.

[0004] Therefore, in order to improve this structure, the present application provides a multi-support fatigue-resistant terminal connector to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a multi-support fatigue-resistant terminal connector to solve the problem that the arc-shaped elastic arm of the existing middle female end will undergo plastic deformation after being squeezed multiple times and for a long time and cannot be restored to its original height.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] It comprises a male terminal, a female terminal, an arc-shaped elastic arm, and also comprises a support arm which provides auxiliary support for the arc-shaped elastic arm, wherein the support arm is used for exerting a lifting force on the arc-shaped elastic arm close to the male terminal.

[0008] Optionally, the support arm is constructed in a “C”-shaped arc shape, and one arc-shaped end of the support arm supports the arc-shaped elastic arm and is arranged in the same direction or opposite to the arc-shaped elastic arm.

[0009] Optionally, the female end is also configured with a first limiting arm for resisting against the arc segment of the supporting arm.

[0010] Optionally, the end of the arc-shaped elastic arm is extended and provided with a curved auxiliary arc-shaped segment.

[0011] Optionally, the curved end of the auxiliary arc segment supports the upper arc segment.

[0012] Optionally, the female end is located outside the auxiliary arc segment and is configured with a second limiting arm, which is used to limit the auxiliary arc segment from moving outward.

[0013] Optionally, the support arm may be integrally constructed on the arc-shaped elastic arm or be provided separately.

[0014] Optionally, the auxiliary arc segment may be integrally constructed on the arc-shaped elastic arm or provided separately.

[0015] Optionally, a third limiting arm for resisting against the other side of the auxiliary arc segment is further constructed in the female end, and the third limiting arm and the second limiting arm are arranged opposite to the auxiliary arc segment.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by integrally constructing a support arm on the arc-shaped elastic arm, and making the support arm bend into an arc to support the bottom of the arc-shaped elastic arm, the arc-shaped elastic arm not only has its own elastic recovery effect but also includes auxiliary reset of the support arm, thereby increasing the elastic reset effect. The present invention configures the support arm into an arc shape similar to a "C" shape, and at the same time, one end of the arc of the support arm supports the arc-shaped elastic arm and is arranged opposite to the arc-shaped elastic arm. In order to prevent the arc-shaped segment of the support arm from being excessively deformed and causing the recovery effect to deteriorate, a first limiting arm for resisting the arc-shaped segment of the support arm is also configured on the female end.

[0031] The embodiment provides a multi-support fatigue-resistant terminal connector, which is mainly used to solve the problem that the arc-shaped elastic arm of the existing female end will be plastically deformed after being squeezed for a long time and cannot be restored to its original height, and provides the following technical solutions. Figure 1-Figure 4 Make a detailed description:

[0032] Embodiment 1:

[0033] A multi-support fatigue-resistant terminal connector, comprising a support arm 4 providing auxiliary support to an arc-shaped elastic arm 3, wherein the support arm 4 is used to apply a lifting force to the arc-shaped elastic arm 3 close to the male terminal 1, see Figure 2 By integrally constructing the support arm 4 on the arc-shaped elastic arm 3, and making the support arm 4 bend into an arc to support the bottom of the arc-shaped elastic arm 3, the arc-shaped elastic arm 3 not only has its own elastic recovery effect but also includes the auxiliary reset of the support arm 4, thereby increasing the elastic reset effect.

[0034] In this embodiment, in order to prevent the support arm 4 from having obvious elastic fatigue after long-term use so that the arc-shaped elastic arm 3 cannot restore to a normal height, the support arm 4 is constructed into a "C"-shaped arc shape, and at the same time, one arc-shaped end of the support arm 4 supports the arc-shaped elastic arm 3 and is arranged opposite to the arc-shaped elastic arm 3. In addition, in order to prevent the arc-shaped segment of the support arm 4 from being excessively deformed, resulting in a poor recovery effect, a first limiting arm 5 for resisting the arc-shaped segment of the support arm 4 is also constructed on the female end 2. Figure 2 As shown in , the first limiting arm 5 can effectively limit the problem of excessive deformation of the supporting arm 4 causing the subsequent inability to recover.

[0035] In this embodiment, in order to further ensure the effect of restoring to a normal height, the end of the arc-shaped elastic arm 3 is extended and provided with a curved auxiliary arc segment 6, and the curved end of the auxiliary arc segment 6 supports the upper arc segment 7. The specific position of the upper arc segment 7 is as follows: Figure 2As shown in the figure, when the upper arc segment 7 is forced, the auxiliary arc segment 6 assists in supporting the upper arc segment 7 to avoid excessive pressure causing the problem of poor recovery effect in the later stage. At the same time, the auxiliary arc segment 6 here is separately arranged and fixed to the mother end 2, and in order to avoid the problem that the auxiliary arc segment 6 cannot recover normally after being forced too many times, the mother end 2 is located on the outside of the auxiliary arc segment 6 and is constructed with a third limiting arm 9, which is used to limit the auxiliary arc segment 6 from moving outward.

[0036] In this embodiment, in order to prevent the end of the extended section of the arc-shaped elastic arm 3 from being excessively displaced outward, a third limiting arm 9 for supporting the end of the extended section of the arc-shaped elastic arm 3 is also constructed in the female end 2. The third limiting arm 9 and the second limiting arm 8 are arranged relative to the auxiliary arc section 6. By setting the second limiting arm 8, the problem of the other end of the arc-shaped elastic arm 3 not being able to return to its original height after being excessively forced due to lack of limitation can be avoided.

[0038] A multi-support fatigue-resistant terminal connector includes a support arm 4 that provides auxiliary support for an arc-shaped elastic arm 3, wherein the support arm 4 is used to apply a lifting force to the arc-shaped elastic arm 3 close to the male terminal 1, see Figure 3 By integrally constructing the support arm 4 on the arc-shaped elastic arm 3, and making the support arm 4 bend into an arc to support the bottom of the arc-shaped elastic arm 3, the arc-shaped elastic arm 3 not only has its own elastic recovery effect but also includes the auxiliary reset of the support arm 4, thereby increasing the elastic reset effect.

[0039] In this embodiment, in order to prevent the support arm 4 from having obvious elastic fatigue after long-term use so that the arc-shaped elastic arm 3 cannot restore to a normal height, the support arm 4 is constructed into a "C"-shaped arc shape, and at the same time, one arc-shaped end of the support arm 4 supports the arc-shaped elastic arm 3 and is arranged opposite to the arc-shaped elastic arm 3. In addition, in order to prevent the arc-shaped segment of the support arm 4 from being excessively deformed, resulting in a poor recovery effect, a first limiting arm 5 for resisting the arc-shaped segment of the support arm 4 is also constructed on the female end 2. Figure 3 As shown in , the first limiting arm 5 can effectively limit the problem of excessive deformation of the supporting arm 4 causing the subsequent inability to recover.

[0040] In this embodiment, in order to further ensure the effect of restoring to a normal height, the end of the arc-shaped elastic arm 3 is extended and provided with a curved auxiliary arc segment 6, and the curved end of the auxiliary arc segment 6 supports the upper arc segment 7. The specific position of the upper arc segment 7 is as follows: Figure 3As shown in the figure, when the upper arc segment 7 is forced, the auxiliary arc segment 6 assists in supporting the upper arc segment 7 to avoid excessive compression leading to poor recovery effect in the later stage. At the same time, the auxiliary arc segment 6 here is formed by self-bending of the extended section of the arc elastic arm 3, and in order to avoid the problem that the auxiliary arc segment 6 cannot recover normally after being forced too many times, the female end 2 is located on the outside of the auxiliary arc segment 6 and is constructed with a third limiting arm 9, which is used to limit the auxiliary arc segment 6 from moving outward.

[0041] In this embodiment, in order to prevent the auxiliary arc segment 6 from excessively shifting to the other side, a second limiting arm 8 for supporting the other side of the auxiliary arc segment 6 is also constructed in the female end 2, and the third limiting arm 9 and the second limiting arm 8 are arranged relative to the auxiliary arc segment 6. By setting the second limiting arm 8, the problem of the other end of the auxiliary arc segment 6 not being able to return to its original height after being over-forced due to lack of limitation can be avoided.

[0044] In this embodiment, in order to prevent the support arm 4 from having obvious elastic fatigue after long-term use so that the arc-shaped elastic arm 3 cannot restore to a normal height, the support arm 4 is constructed into a "C"-shaped arc shape, and at the same time, one arc-shaped end of the support arm 4 supports the arc-shaped elastic arm 3 and is arranged in the same direction as the arc-shaped elastic arm 3. In addition, in order to prevent the arc-shaped segment of the support arm 4 from being excessively deformed, resulting in a poor recovery effect, a first limiting arm 5 for resisting the arc-shaped segment of the support arm 4 is also constructed on the female end 2. Figure 4 As shown in , the first limiting arm 5 can effectively limit the problem of excessive deformation of the supporting arm 4 causing the subsequent inability to recover.

[0045] In this embodiment, in order to further ensure the effect of restoring to a normal height, the end of the arc-shaped elastic arm 3 is extended and provided with a curved auxiliary arc segment 6, and the curved end of the auxiliary arc segment 6 supports the upper arc segment 7. The specific position of the upper arc segment 7 is as follows: Figure 4As shown in the figure, when the upper arc segment 7 is forced, the auxiliary arc segment 6 assists in supporting the upper arc segment 7 to avoid excessive compression leading to poor recovery effect in the later stage. At the same time, the auxiliary arc segment 6 here is formed by self-bending of the extended section of the arc elastic arm 3, and in order to avoid the problem that the auxiliary arc segment 6 cannot recover normally after being forced too many times, the female end 2 is located on the outside of the auxiliary arc segment 6 and is constructed with a third limiting arm 9, which is used to limit the auxiliary arc segment 6 from moving outward.

[0046] In this embodiment, in order to prevent the auxiliary arc segment 6 from excessively shifting to the other side, a second limiting arm 8 for supporting the other side of the auxiliary arc segment 6 is also constructed in the female end 2, and the third limiting arm 9 and the second limiting arm 8 are arranged relative to the auxiliary arc segment 6. By setting the second limiting arm 8, the problem of the other end of the auxiliary arc segment 6 not being able to return to its original height after being over-forced due to lack of limitation can be avoided.
