Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a spring-loaded connector. Background Technology

[0002] Currently, most existing Bluetooth headsets and other electronic products come with charging cases. When these products are placed in the charging case for charging or signal transmission, a stable contact method is needed to ensure stable contact within the case. To achieve more stable charging or signal transmission, spring contacts can be installed inside the charging case. However, for side-mounted charging spring contacts, they are typically made quite thin to maintain their elasticity. Yet, they are required to operate continuously and efficiently within their designed range to prevent scratches, detachment, and failure. This leads to insufficient strength and a short lifespan after prolonged use. Utility Model Content

[0027] This application is described in detail below. Examples of embodiments of this application are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0028] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features, elements, and / or components, but does not exclude the presence or addition of one or more other features, elements, components, and / or groups thereof. The term “and / or” as used herein includes all or any units and all combinations thereof of one or more associated listed items.

[0029] like Figure 1-4As shown, this application embodiment provides a spring-loaded connector, including a side guard 1, a suction part 2, and an elastic part 3. The side guard 1 includes a first side guard 11 and a second side guard 12, which are disposed opposite to each other. The suction part 2 is disposed at the top ends of the first side guard 11 and the second side guard 12, closing the top ends of the first side guard 11 and the second side guard 12; the elastic part 3 is disposed between the first side guard 11 and the second side guard 12. The top end of the first side guard 11 is bent and extends laterally to the top end of the second side guard 12 to form the suction part 2; the top end of the second side guard 12 is provided with a locking part 121, and the suction part 2 at a position corresponding to the locking part 121 is provided with an overlapping part 21; the overlapping part 21 fastens to the locking part 121 of the second side guard 12, closing the top ends of the first side guard 11 and the second side guard 12. This forms a locking structure, further enhancing the strength of the entire side guard 1, preventing the side guard 1 from being pried open, and thus protecting the elastic part 3 between the two side guards 1, extending the service life of the spring.

[0030] like Figure 2 As shown, a support arm 4 is provided between the rear end faces of the first side guard 11 and the second side guard 12. A reinforcing rib 41 is provided in the middle of the support arm 4, and the thickness of the reinforcing rib 41 is greater than the thickness of other parts of the support arm 4. This can increase the strength of the support arm 4, thereby increasing the strength of the spring contact seat and extending the service life of the spring contact seat.

[0031] like Figure 3 As shown, the elastic part 3 includes a bending part 31, a support part 32, a first elastic arm 33, a contact part 34, a second elastic arm 35, and a limiting part 36. The bending part 31 is formed by bending upwards from one longitudinal edge of the support arm 4, and the bending part 31 is U-shaped. The bending part 31 extends horizontally to form the support part 32; the support part 32 extends obliquely upwards and away from the support part 32 to form the first elastic arm 33, which is L-shaped. The distal end of the first elastic arm 33 is provided with a contact part 34, which is curved. The contact part 34 bends and extends in the opposite direction to form the second elastic arm 35. The end of the second elastic arm 35 is provided with a limiting part 36, which is T-shaped.

[0032] like Figure 2-4As shown, a limiting piece 361 is provided at the lower end of the suction part 2 and at the top of the first side guard 11 and the second side guard 12. The limiting piece 361 is connected to and opposite to the sides of the first side guard 11 and the second side guard 12, and the limiting piece 361 is bent into an L-shape. The limiting part 36 is movably disposed between the first side guard 11 and the second side guard 12, and the limiting piece 361 limits the limiting part 36. Thus, by limiting the limiting part 36 with the limiting piece 361, the limiting part 36 will not detach from the limiting piece 361 and will not move up and down between the side guards 1. When an electronic product that needs to be charged enters the charging compartment, the charging terminal will apply a backward or downward force to the contact part 34. At this time, the limiting part 36 slides down or backward along the inner wall edge of the limiting piece 361 or the side guard 1 until the applied force disappears after the electronic product being charged has completely entered the charging compartment, at which point the limiting part 36 stops sliding backward or downward. However, when the limiting part 36 slides downward or backward, it will not detach from the side guard part 1 and the limiting piece 361. The limiting part 36 and the limiting piece 361 are also provided to prevent the elastic part 3 from being pulled off or deformed when an external force pulls on it.

[0033] like Figure 1 and 2 As shown, a first connecting part 42 is provided below the support arm 4, and two second connecting parts 43 are provided below the side guard 1 near the support arm 4. With three connecting parts, whether soldered or plugged into the circuit board, the spring contact connector can be effectively fixed to the circuit board, ensuring stable and secure charging or signal transmission.

[0034] like Figure 1 As shown, a laterally bent and mutually close lever arm 13 is provided on the side guard 1 near the first elastic arm 33, and the side guard 1 is S-shaped. This can improve the stress resistance of the side guard 1. When the force received by the contact part 34 is transmitted to the side guard 1, the side guard 1 will not be squeezed and deformed. The side guard 1 will give the elastic part 3 a reverse force, thus enhancing the strength of the spring piece (i.e., the elastic force of the elastic part 3) and extending the service life of the spring piece connecting seat.

[0035] The entire spring connector is made into a single piece. It can be made by cutting and manufacturing easily bendable metal sheets, leaving the parts in the corresponding positions, and then bending and assembling them.

[0036] The spring connector of this application is suitable for headphone charging devices, such as headphone charging cases. It has advantages such as simple molding, more secure connection (fixed by plugging or welding), shorter length, smaller structure, and space saving. In the working state, the entire spring (elastic part 3) is protected, without affecting the normal functional characteristics of the spring and ensuring its efficient operation.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
