Description

Technical Field

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

[0002] In electronic devices or systems, devices that connect two or more circuits are generally called electrical connectors, or simply connectors. These connectors are fundamental components for achieving electrical connections and signal transmission between circuits, and are widely used in the internal and external connections of various electronic products.

[0003] However, in the existing technology, when a direct and efficient connection between the host circuit board and the battery is required, the existing connectors are often difficult to achieve this connection directly. Usually, additional structural optimization design or special adapters are required to complete the connection task. This not only increases the complexity of the connection, but may also introduce additional connection losses or unreliability.

[0004] Secondly, existing connectors are typically designed in a relatively simple way, with each connection unit or contact often having only a single functional structure, such as being used solely for conducting current. Connectors with this design suffer from poor overall lifespan and fatigue resistance, and their conductivity and heat dissipation capabilities are also limited, making it difficult to maintain stable and reliable performance in high-current or high-power applications.

[0005] Based on this, in order to further optimize the applicability and durability of existing connectors, we propose a spring-loaded connector. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing connectors, such as their generally simple design, poor overall service life and fatigue resistance, and limited conductivity and heat dissipation capabilities. This invention proposes a spring-loaded connector.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: Design a spring-loaded connector, including: A base equipped with several mounting slots; Pins are fixedly installed in the mounting slot; The pin includes a contact portion, a first bent portion, a second bent portion, a third bent portion, and a connecting pin; The third bend is detachably connected to the mounting groove.

[0008] Furthermore, the first, second, and third bends are all U-shaped bends, and the connecting leg is bent vertically at the tail end of the third bend.

[0009] Furthermore, the bottom sides of the mounting groove are provided with insertion positions, and the bottom sides of the third bend are formed with extensions, which are inserted into the insertion positions.

[0010] Furthermore, a groove is provided on the side of the mounting slot, an elastic sheet is formed inside the groove, and a locking protrusion is formed on the end face of the elastic sheet, which stops the inner side of the third bend.

[0011] Furthermore, the contact portion includes a contact foot connected to the first bent portion and an extension arm formed on the side of the contact foot, and a reinforcing plate is also fixedly installed on the upper surface of the contact foot.

[0012] Furthermore, a nickel plating layer is provided on the outer side of the pin, and a gold plating layer is also provided on the outer side of the nickel plating layer at the connection between the pin and the reinforcing sheet.

[0013] Furthermore, the base is a plastic part, and its bottom is formed with positioning posts, and ten mounting slots are configured on the base.

[0014] The advantages of the spring-loaded connector proposed in this utility model are as follows: Firstly, the connector uses pins for electrical connection between the battery and the circuit board, enabling direct connection between the main battery board and the battery without the need for structural optimization or adapters. Secondly, the bending design of the first, second, and third bends can distribute or decompose the fatigue load, conductive current, and heat dissipation capacity of the connector, thereby achieving fatigue resistance and conductive stability, thus ensuring the applicability and durability of the connector.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 As one embodiment of this utility model, a spring-loaded connector is disclosed. Specifically, the connector includes a base 1 configured with a plurality of mounting slots 10; pins 2 are fixedly installed in the mounting slots 10. Specifically, in this embodiment, the base 1 is fixed on the circuit board, and the pins 2 are used to electrically connect the battery and the circuit board, so as to achieve direct connection between the main battery board and the battery without the need for conversion through related structural optimization or adapter devices. The pin 2 includes a contact portion 21, a first bent portion 22, a second bent portion 23, a third bent portion 24, and a connecting foot 25; the third bent portion 24 is detachably connected to the mounting groove 10.

[0019] In some embodiments, the first bending portion 22, the second bending portion 23, and the third bending portion 24 of this utility model are all bent in a U-shape. In this embodiment, the first bending portion 22, the second bending portion 23, and the third bending portion 24 together form a continuous S-shaped structure, and the connecting leg 25 is bent vertically at the tail end of the third bending portion 24.

[0020] In other words, by employing the bending design of the first bending portion 22, the second bending portion 23, and the third bending portion 24 on the pin 2 in this utility model, the fatigue load, conductive current, and heat dissipation capacity of the connector can be distributed or decomposed, thereby achieving the effects of fatigue resistance and conductive stability. In addition, the contact portion 21, the first bending portion 22, the second bending portion 23, the third bending portion 24, and the connecting foot 25 described in this embodiment are integrally formed. The entire pin 2 can be stamped using a metal mold, thus achieving the advantages of high consistency, high production efficiency, and low manufacturing cost.

[0021] Based on the above embodiments, in this embodiment, the bottom sides of the mounting groove 10 are provided with insertion positions 11, and the bottom sides of the third bending portion 24 are formed with extension portions 241. The extension portions 241 are inserted into the insertion positions 11. That is, when installing the entire pin 2, the extension portions 241 on both sides of the bottom of the third bending portion 24 can be inserted into the insertion positions 11 of the mounting groove 10, and then the entire pin 2 is pushed inward until the extension portions 241 slide to the innermost position of the insertion position 11, thus completing the insertion and positioning of the pin 2.

[0022] It should be noted that the insertion position 11 described in this embodiment does not extend to the rear end face of its mounting groove 10, that is, it has a sliding limiting length for the extension part 241. When the extension part 241 slides to the innermost position of the insertion position 11, the entire pin 2 can no longer move inward.

[0023] When pin 2 slides inward inside the mounting groove 10, the upper and lower limits of the entire pin 2 can be achieved by means of the cooperation of the extension part 241 and the insertion position 11. Of course, in order to lock the front and rear positions of pin 2 after installation, a groove is provided on the side of the mounting groove 10 in this embodiment. An elastic sheet 12 is formed inside the groove, and a locking protrusion 13 is formed on the end face of the elastic sheet 12. The locking protrusion 13 stops on the inner side of the third bending part 24.

[0024] In this embodiment, the design of the latch 13 is used to achieve the insertion and positioning of the third bent part 24. It should be noted that the front end of the latch 13 in this embodiment is set as a beveled structure, and the rear side of the latch 13 is set as a circular structure. When the third bent part 24 is inserted, it will first abut against the bevel of the latch 13 to deform and shrink until the extension part 241 slides to the innermost position of the insertion position 11. The latch 13 rebounds and resets under the action of the elastic sheet 12. Then its circular structure abuts against the inner side of the third bent part 24. In this way, the upper, lower and front and rear limits of the third bent part 24 can be completed to fix the pin 2 on the base 1. Of course, when disassembling, press the latch 13 to deform it and disengage it from the third bent part 24. At this time, the third bent part 24 can be slid outward to achieve disassembly.

[0025] In some embodiments, the contact portion 21 of this invention includes a contact foot 211 connected to the first bent portion 22 and an extension arm 212 formed on the side of the contact foot 211. A reinforcing piece 213 is also fixedly mounted on the upper surface of the contact foot 211. It should be noted that the connecting foot 25 in this embodiment is fixed on the circuit board. The contact foot 211 is used to contact the electrode of the battery. By providing a reinforcing piece 213 at the contact foot 211 and the battery conduction point, the contact surface pressure is increased and the contact resistance is reduced, thereby optimizing the circuit conduction performance.

[0026] In addition, in this embodiment, a nickel plating layer 15 is provided on the outer side of the pin 2. At the connection between the pin 2 and the reinforcing sheet 213, a gold plating layer 16 is also provided on the outer side of the nickel plating layer 15. In this embodiment, the surface of the pin 2 is electroplated to form the nickel plating layer 15. Preferably, the thickness of the nickel plating layer 15 is about 80 microinches, which is used to isolate environmental factors, prevent oxidation, and withstand salt spray tests for up to 96 hours. At the connection between the pin 2 and the reinforcing sheet 213, a gold plating layer 16 is electroplated on the nickel plating layer 15. This facilitates the welding of the reinforcing sheet 213, enhances corrosion resistance, and maintains excellent conductivity.

[0027] It should be noted that, in this embodiment, the base 1 is a plastic part, and a positioning post 14 is formed on its bottom. Ten mounting slots 10 are configured on the base 1.

[0028] In summary, this utility model uses pin 2 for electrical connection between the battery and the circuit board, enabling direct connection between the main circuit board and the battery without the need for structural optimization or adapters. Secondly, the bending design of the first bending part 22, the second bending part 23, and the third bending part 24 can distribute or decompose the fatigue load, conductive current, and heat dissipation capacity of the connector, thereby achieving fatigue resistance and conductive stability, thus ensuring the applicability and durability of the connector.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
