Description

Technical Field

[0001] This utility model belongs to the field of PogoPin technology, and in particular relates to a direct-connect, split-type, high-current PogoPin spring pin. Background Technology

[0002] In the current PogoPin industry, products with high current carrying capacity generally employ two types of structures. The first is a direct-through / integrated PogoPin product. When the pin conducts electricity, current is input at the tail of the needle and output at the tip. Current conduction is completed entirely within the same component at the tip; the needle tube does not participate in current transmission and has no current transmission capability. The second is a split-type design. Based on the ordinary split-type design, the internal structure and stress optimization are enhanced, enabling the pin to carry high current. When the pin conducts electricity, current is input at the tail of the needle tube and output at the tip. Current conduction is carried out from the needle tube to the tip; in this type of structure, both the needle tube and the tip participate in current transmission. The conduction principles of these two structures differ significantly. During selection, the PCB circuit needs to be planned in advance based on the components, and flexible switching cannot be achieved later. In some special scenarios, especially in the early stages of product development and verification, it is impossible to avoid these issues in advance. Utility Model Content

[0003] The purpose of this invention is to provide a high-current PogoPin spring pin that can be used for both direct and split applications, in order to solve the technical problem that existing PogoPin spring pins do not have the ability to be used for both direct and split applications.

[0004] To achieve the above objectives, this utility model provides a direct-flow, split-type, high-current PogoPin spring needle, comprising a needle head, a needle tube, a spring, a pressure guide ring, and multiple conductive beads. The needle head has an outer ring around its outer periphery, the needle tube has an inner ring at its inner bottom, and the pressure guide ring has an inner groove at its bottom. The pressure guide ring is placed on the inner ring of the needle tube. The spring is sleeved around the outer periphery of the needle head. The needle head passes through the pressure guide ring and the inner ring of the needle tube at the top of the needle tube. The two ends of the spring abut against the pressure guide ring and the outer ring of the needle head, respectively. The top of the needle tube is riveted inwards to form a chamfered portion that restricts the outer ring of the needle head. Each conductive bead is arranged in a ring outside the needle head and confined within the area enclosed by the inner groove and the inner ring of the needle tube.

[0005] Optionally, the inner groove is a conical groove, and the inclined surface of the conical groove contacts the conductive bead.

[0006] Optionally, the needle, the needle tube, the pressure guide ring, and the conductive bead are all made of brass and have a gold-plated layer on their surfaces.

[0007] Optionally, the needle tube is provided with a needle tube outer ring on its outer periphery.

[0008] Optionally, the outer periphery of the needle tube is further provided with an inwardly contracting annular groove, which is located below the outer ring of the needle tube.

[0009] The above-mentioned technical solutions of one or more of the direct-through and split-type high-current PogoPin spring needles provided in this utility model embodiment have at least one of the following technical effects: The direct-through and split-type high-current PogoPin spring needles of this utility model are suitable for two working environments. In the client application, wires can be welded to the tail of the pressure guide ring through the needle tip of this utility model, and it can be used as a direct-through PogoPin product, which can stably pass high current. In other scenarios, wires can be welded to the outer wall of the needle tube of this utility model, or the outer diameter of the needle tube can be kept conductive, and the tail extension position of the needle tip can be left empty at the bottom of the host, so as to use it as a split-type PogoPin product. The direct-through and split-type high-current PogoPin spring needles of this utility model have a high current conduction capability, which is better and more stable than conventional split-type PogoPin products.

[0019] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-3 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0020] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0023] In one embodiment of this utility model, such as Figures 1-3As shown, a direct-connect, split-type, high-current PogoPin spring needle is provided, including a needle head 10, a needle tube 20, a spring 30, a pressure guide ring 40, and multiple conductive beads 50. The outer periphery of the needle head 10 is provided with a needle head outer ring 11, the bottom of the inner periphery of the needle tube 20 is provided with a needle tube inner ring 21, the bottom of the pressure guide ring 40 is provided with an inner groove 41, and the pressure guide ring 40 is placed on the needle tube inner ring 21. The spring 30 is sleeved on the outer periphery of the needle head 10. The needle head 10 passes through the pressure guide ring 40 and the needle tube inner ring 21 at the top of the needle tube 20. The two ends of the spring 30 abut against the pressure guide ring 40 and the needle head outer ring 11, respectively. The top of the needle tube 20 is riveted inward to form a chamfered portion 22 that restricts the needle head outer ring 11. Each of the conductive beads 50 is arranged in a ring outside the needle head 10 and is restricted within the area formed by the inner groove 41 and the needle tube inner ring 21.

[0024] In one embodiment, the conductive beads 50 are preferably eight.

[0025] This invention relates to a direct-through, split-type, high-current PogoPin spring-loaded needle suitable for two working environments. In client applications, wires can be soldered through the tail of the pressure guide ring 40 of the needle 10, allowing it to be used as a direct-through PogoPin product, which can stably carry high current. In other scenarios, wires can be soldered to the outer wall of the needle tube 20, or the outer diameter of the needle tube 20 can be kept conductive, leaving the tail of the needle 10 at the bottom of the main unit empty, thus using it as a split-type PogoPin product. This invention provides a high-current conduction capability, which is better and more stable than conventional split-type PogoPin products.

[0026] In another embodiment of this utility model, the inner groove 41 is a conical groove, and the inclined surface 411 of the conical groove contacts the conductive bead 50. Specifically, according to the preset angle formed by the contact between the inclined surface 411 of the conical groove and the conductive bead 50, when the inclined surface 411 of the conical groove of the pressure guide ring 40 contacts the conductive bead 50, the vertical pressure is decomposed into an oblique force pointing downward towards the center. Since the conductive bead 50 surrounds the needle 10, when subjected to centripetal force, the conductive bead 50 and the needle 10 make sufficient contact, and there is good conductivity between the needle 10 and the conductive bead 50. At the same time, due to the vector decomposition of force, the downward pressure will continue to be maintained, and the conductive bead 50 and the bottom of the needle tube 20 also make sufficient contact, and there is good conductivity between the conductive bead 50 and the needle tube 20.

[0027] Furthermore, such as Figure 2As shown, the arrows within the cross-section indicate the current. It can conduct electricity directly from the contact surface at the top of the needle 10 to its tail below, or from the contact point between the needle 10 and the conductive bead 50 to the contact point between the needle tube 20 and the conductive bead 50. Thus, the needle 10 can directly transmit a large current, and after contact with multiple conductive beads 50, the needle tube 20 can also transmit a large current. This combines the advantages of two different structural designs into one.

[0028] In another embodiment of this invention, the needle 10, the needle tube 20, the pressure guide ring 40, and the conductive bead 50 are all made of brass and have a gold-plated layer on their surface. Using brass and further plating a gold-plated layer on its surface effectively enhances its conductivity.

[0029] In another embodiment of this utility model, an outer ring 23 is provided on the outer periphery of the needle tube 20. The outer ring 23 can serve as a positioning structure during the installation and use of the entire PogoPin spring needle product, facilitating the insertion of the needle tip 10.

[0030] In another embodiment of this invention, an inwardly recessed annular groove 24 is further provided on the outer periphery of the needle tube 20, and the inwardly recessed annular groove 24 is located below the outer ring 23 of the needle tube. This inwardly recessed annular groove 24 facilitates the guiding and installation of the PogoPin spring needle product.

[0031] The straight-through, split, dual-purpose high-current PogoPin spring pin of this utility model embodiment has the following features:

[0032] 1. The parts consist of five types: needle 10, needle tube 20, spring 30, pressure guide ring 40, and conductive bead 50.

[0033] Except for spring 30, all other parts are made of brass with gold plating to improve the product's oxidation resistance and reduce contact resistance when conducting.

[0034] 2. The main function of the conductive bead 50 and the pressure guide ring 40 is to decompose the vertically downward pressure into lateral force, so that the conductive bead 50 can make full contact with the needle 10 and the needle tube 20.

[0035] 3. It is preferable to use eight beads to maintain force balance and prevent abnormalities such as eccentricity or skewness when the conductive bead 50 shakes inside.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
