Description

Technical Field

[0001] The utility model relates to the technical field of contact springs, in particular to a new type of contact spring. Background Art

[0002] The contact spring provides a path for conducting telecommunications between the connector and the component. In mobile communication devices, in order to facilitate assembly, disassembly, maintenance and replacement, some electrical components are usually connected to circuit boards and batteries through contact springs. One end of the contact spring is fixed to the circuit board, and the other end can elastically mechanically contact the electrical component to complete the electrical connection between the two.

[0003] The patent number is: ZL202220961517.7, and the patent name is: A Chinese utility model patent for a double-contact simple spring-type connector, which essentially discloses a contact spring structure; specifically, the double-contact simple spring-type connector includes a rectangular welding portion, and the side of the welding portion is connected to an elastic contact arm, and the elastic contact arm includes an inclined force arm and a contact portion, one end of the inclined force arm is connected to the welding portion, and the other end of the inclined force arm is connected to the contact portion.

[0004] It should be pointed out that the above-mentioned dual-contact simple spring-clip connector has the following defects. Specifically, since the elastic contact arm (elastic contact portion) is directly connected to the side position of the welding portion, when an external force acts on the elastic contact arm and causes the elastic contact arm to deform elastically, the elastic contact arm as a whole will elastically deflect relative to the welding portion. Once the external force is too large, the entire elastic contact arm will not be able to rebound. That is, the dual-contact simple spring-clip connector has the defects of poor elastic deformation ability and poor structural stability and reliability. Utility Model Content

[0005] The utility model aims to provide a new contact spring piece in view of the deficiencies in the prior art. The new contact spring piece has a novel design, a strong elastic deformation capability, a stable structure and good reliability.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions.

[0027] The present invention will be described below in conjunction with specific implementation methods.

[0028] Embodiment 1, as Figures 1 to 3 As shown, a new contact spring comprises a welding portion 1 and an elastic contact portion 2, wherein the welding portion 1 is arranged horizontally.

[0029] Among them, Figures 1 to 3 As shown, an elastic arm support portion 3 is connected between the welding portion 1 and the elastic contact portion 2, and the elastic arm support portion 3 includes an inclined straight plate section 31 and an "n"-shaped arched curved section 32. The lower end of the inclined straight plate section 31 is connected to the left edge of the welding portion 1, and the inclined straight plate section 31 gradually extends straightly from bottom to top toward the upper right, and the right edge of the arched curved section 32 is connected to the upper edge of the inclined straight plate section 31.

[0030] Furthermore, the elastic contact portion 2 is located at the left end side of the inclined straight plate section 31 , and the upper edge of the elastic contact portion 2 is connected to the left edge of the arched curved section 32 .

[0031] Furthermore, the welding part 1, the elastic contact part 2, and the elastic arm support part 3 are an integrated structure, and the new contact spring piece is in the shape of "2". It should be explained that the new contact spring piece of the first embodiment can be processed by punching and bending a stainless steel sheet.

[0032] It should be pointed out that, for the new contact spring piece of the first embodiment, the elastic contact portion 2 and the welding portion 1 are arranged at intervals instead of being directly connected, and the elastic contact portion 2 is connected to the welding portion 1 through the elastic arm support portion 3; the elastic arm support portion 3 includes an inclined straight plate section 31 and an arched curved section 32, and the inclined straight plate section 31 gradually extends in a straight line from bottom to top toward the upper right, that is, a certain elastic deformation can be achieved between the inclined straight plate section 31 and the welding portion 1; the arched curved section 32 is in an "n" shape, and the arched curved section 32 of this shape design can itself achieve a certain elastic deformation; the elastic contact portion 2 and the inclined straight plate section 31 are arranged at intervals, and the gap between the two can enable the elastic contact portion 2 to have sufficient elastic deformation space; therefore, compared with the prior art, the new contact spring piece of the first embodiment has the advantage of strong elastic deformation ability.

[0033] In addition, when a large external force acts on the elastic contact part 2, since the elastic contact part 2 and the elastic arm support part 3 can both achieve elastic deformation, and the elastic arm support part 3 can effectively buffer the external force, the contact spring of this structural design can effectively avoid the problem that the elastic contact part 2 cannot rebound due to excessive external force, that is, it has the advantage of good structural stability and reliability.

[0034] In summary, it can be seen that, through the above structural design, the new contact spring of the first embodiment has the advantages of novel design, strong elastic deformation ability, and good structural stability and reliability.

[0035] Embodiment 2, as Figures 1 to 3 As shown, the difference between the second embodiment and the first embodiment is that the elastic contact portion 2 includes a first side arm 21 and a second side arm 22, the upper edge of the second side arm 22 is connected to the left edge of the arched curved section 32, and the second side arm 22 gradually extends from top to bottom toward the lower left.

[0036] The lower end of the second side arm 22 is connected to the upper end of the first side arm 21 , and the connection between the first side arm 21 and the second side arm 22 adopts an arc transition.

[0037] It should be noted that the elastic contact portion 2 is in an inverted V shape that is arched toward the left side as a whole.

[0038] The elastic contact portion 2 designed in the above shape can effectively ensure its elastic deformation capability.

[0039] Embodiment 3: The difference between Embodiment 3 and Embodiment 2 is that: the angle between the first side arm 21 and the second side arm 22 is 135 degrees.

[0040] Embodiment 4: The difference between Embodiment 4 and Embodiment 1 is that the angle between the inclined straight plate section 31 and the welding portion 1 is 85 degrees.

[0041] Embodiment 5, as Figure 1 and Figure 2 As shown, the difference between the fifth embodiment and the first embodiment is that the lower end of the inclined straight plate section 31 is in a wedge shape that is narrow at the top and wide at the bottom.

[0042] Since the lower end of the inclined straight plate section 31 is narrow at the top and wide at the bottom, the inclined straight plate section 31 designed in this shape can make the elastic arm support part 3 have a strong supporting strength, thereby effectively ensuring the rebound performance of the elastic arm support part 3.

[0043] Embodiment six, as Figure 1 and Figure 2 As shown, the difference between the sixth embodiment and the first embodiment is that a plurality of tooth grooves 11 arranged at intervals and penetrating vertically are formed on the edge of the welding portion 1 .

[0044] When the soldering portion 1 is soldered onto a circuit board, the tooth groove 11 structure provided at the edge of the soldering portion 1 can effectively increase the contact area between the soldering portion 1 and the tin material, thereby effectively improving the soldering quality.

[0045] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
