[0031] In some cases, for traditional Pogopin connectors, hard interference connectors are usually used. It is laborious for operators to plug and unplug, has high requirements for alignment accuracy, and the connectors are easily damaged after long-term plugging and unplugging.
[0032] Based on the above situation, an embodiment of the present application proposes a non-hard interference magnetic Pogopin connector, aiming to enable operators to plug and unplug, and also facilitate the alignment of the connector and extend the service life of the connector.
[0033] The following further elaborates on each embodiment of the non-hard interference magnetic Pogopin connector of the present application with reference to the accompanying drawings.
[0034] As Figure 1 shown, Figure 1 is a schematic cross-sectional structure diagram of a non-hard interference magnetic Pogopin connector provided by an embodiment of the present application.
[0035] In one embodiment, a magnetic attraction type Pogopin connector without hard interference includes a Pogopin male connector 100 and a Pogopin female connector 200. The Pogopin male connector 100 is provided with a first electromagnet 110 and a retractable pin 120, and the Pogopin female connector 200 is provided with a first magnetic attraction component 210 and a contact component 220. Wherein, when the Pogopin male connector 100 and the Pogopin female connector 200 are combined, the pin 120 is in elastic contact with the contact component 220, and the positions of the first electromagnet 110 and the first magnetic attraction component 210 correspond to each other.
[0036] A Pogopin connector is a precision spring type electronic connector, and its working principle is to provide a contact force through an internal spring to establish a stable electrical connection between the needle and the mating part.
[0037] Wherein, the Pogopin male connector 100 can supply power to make the first electromagnet 110 generate magnetic force, so that the first electromagnet 110 attracts the first magnetic attraction component 210. Finally, the Pogopin male connector 100 and the Pogopin female connector 200 can be firmly combined by magnetic attraction.
[0038] In addition, regarding the contact component 220 of the Pogopin female connector 200, it can be a conductive groove, a copper column, a solder pad, or other structures, and the embodiments of the present application do not make specific limitations thereto.
[0039] In addition, in the embodiments of the present application, an electric control system is used to control the suction force of the first electromagnet 110, and the operator only needs to gently push the test board in to achieve tight suction.
[0040] The embodiments of the present application use an electromagnet and a Pogopin to form a general-purpose connector, which solves the problem of difficult insertion and extraction of hard interference connectors. In addition, since the alignment accuracy requirements for using hard interference connectors are extremely high, changing to the Pogopin in the embodiments of the present application can reduce the accuracy requirements and is more suitable for engineering use. In addition, using the combination method of the electromagnet can also solve the problem of the connection stability of the Pogopin.
[0041] Wherein, this connection method can be used for various test boards that are frequently inserted and extracted. Installing one end of it in an aging box has particularly remarkable effects.
[0042] In addition, as Figure 2 shown, Figure 2 is a cross-sectional structural schematic diagram of a magnetic attraction type Pogopin connector without hard interference provided by another embodiment of the present application.
[0043] In one embodiment, the aging test connector device is further provided with a second magnetic attraction member 300 in a U shape, and the Pogopin male connector 100 and the Pogopin female connector 200 are both provided with a second electromagnet 130 corresponding to the end positions of the second magnetic attraction member 300; wherein, when the Pogopin male connector 100 and the Pogopin female connector 200 are combined, the inner side of the second magnetic attraction member 300 wraps the edge portions of the Pogopin male connector 100 and the Pogopin female connector 200.
[0044] Specifically, after the Pogopin male connector 100 and the Pogopin female connector 200 are combined with each other, in order to further fasten the Pogopin male connector 100 and the Pogopin female connector 200, the embodiment of the present application can wrap the edge portions of the Pogopin male connector 100 and the Pogopin female connector 200 with the U-shaped second magnetic attraction member 300 at the same time, so that the Pogopin male connector 100 and the Pogopin female connector 200 cannot be separated; at the same time, the second magnetic attraction member 300 will also be attracted to the second electromagnet 130, so that the second magnetic attraction member 300 cannot fall off.
[0045] In one embodiment, the Pogopin male connector 100 is provided with a first anti-fooling structure, and the Pogopin female connector 200 is provided with a second anti-fooling structure, and the shapes and sizes of the first anti-fooling structure and the second anti-fooling structure correspond to each other.
[0046] For the anti-fooling design, the Pogopin male connector 100 and the Pogopin female connector 200 can be prevented from being inserted reversely in the following forms:
[0047] 1. Notch or groove design: Set asymmetric notches or grooves so that insertion can only be performed in the correct direction. For example: The Pogopin male connector 100 and the Pogopin female connector 200 adopt an asymmetric concave-convex groove fit, and can only be inserted when correctly aligned.
[0048] 2. Polarity marking: Set obvious polarity markings (such as positive and negative markings) at the interfaces of the Pogopin male connector 100 and the Pogopin female connector 200 to ensure that users can only insert in the correct direction and avoid circuit short circuits or other damages caused by reverse insertion.
[0049] 3. Locking mechanism: A forced locking mechanism is set in the connector, which can only be locked when correctly inserted to prevent the plug from being improperly inserted or inserted in the wrong direction. For example: The Pogopin male connector 100 and the Pogopin female connector 200 adopt a snap design, and the snap will automatically lock only when correctly inserted in opposite directions.
[0050] 4. Outer shape design: By designing a unique outer shape, only the Pogopin male connector 100 that meets the requirements can be inserted into the corresponding Pogopin female connector 200. For example: Different sizes or shapes of interfaces are adopted to ensure that only the correctly matched plug can be inserted.
[0051] 5. Color or mark distinction: Clear colors or marks are marked on the Pogopin male connector 100 and the Pogopin female connector 200 to help users quickly identify the correct insertion direction. For example: Colors such as red, yellow, blue, and green are used for distinction, which is convenient for users to quickly distinguish and avoid incorrect insertion.
[0052] 6. Matching design: By designing different pin shapes and sizes, only the correct Pogopin male connector 100 can be inserted into the correct Pogopin female connector 200.
[0053] In addition, as Figure 3 shown, Figure 3 is a schematic cross-sectional structure diagram of the pin 120 of the Pogopin male connector 100 provided by an embodiment of the present application.
[0054] In one embodiment, the pin 120 includes a needle tip 121, a spring 122, and a needle tube 123. The spring 122 is installed in the inner cavity of the needle tube 123, and one end of the spring 122 is arranged at the bottom of the inner cavity of the needle tube 123. A part of the needle tip 121 is embedded in the inner cavity of the needle tube 123 and is arranged at the other end of the spring 122. The other part of the needle tip 121 is used for elastic contact with the contact component 220.
[0055] Among them, the needle tip 121 is usually made of brass alloy and is gold-plated on the surface for contact with the docking part. The needle tube 123 plays a role in support and conduction, and the inner wall is smooth and is usually made of brass alloy. The spring 122 is used to provide a contact force to ensure good contact between the needle tip 121 and the docking part.
[0056] In addition, as Figure 4 shown, Figure 4 is a schematic cross-sectional structure diagram of the pin 120 of the Pogopin male connector 100 provided by another embodiment of the present application.
[0057] In one embodiment, a ring-shaped limiting groove 123a is provided around the inner cavity of the syringe barrel 123, and a ring-shaped limiting protrusion 121a is provided around the needle head 121. The limiting protrusion 121a is used to move up and down within the limiting groove 123a.
[0058] Among them, in the embodiment of the present application, through the limiting structure of the limiting groove 123a and the limiting protrusion 121a, the needle head 121 can be prevented from being pressed in too much, thereby protecting the nozzle of the syringe barrel 123 from being bruised.
[0059] In addition, as Figure 5 shown, Figure 5 FIG. is a schematic cross-sectional structure diagram of the pin 120 and the conductive groove provided by an embodiment of the present application.
[0060] In one embodiment, when the contact component 220 is a conductive groove, a first conductive layer 221 is provided on the bottom and around the conductive groove; the top of the needle head 121 is used to contact the first conductive layer 221 at the bottom of the conductive groove; an elastic conductive layer 121b is provided around the needle head 121. During the telescopic process of the pin 120, the periphery of the needle head 121 elastically slides in contact with the first conductive layer 221 around the conductive groove through the elastic conductive layer 121b.
[0061] Specifically, if there is a momentary looseness between the Pogopin male connector 100 and the Pogopin female connector 200, resulting in the top of the needle head 121 being unable to maintain electrical contact with the bottom of the conductive groove, the needle head 121 can still maintain electrical contact with the first conductive layer 221 around the conductive groove through the elastic conductive layer 121b around it, so as to maintain the electrical connection between the Pogopin male connector 100 and the Pogopin female connector 200, ensuring the aging test.
[0062] In one embodiment, the inside of the elastic conductive layer 121b is an elastic filling material, and a conductive coating is sprayed on the surface of the elastic conductive layer 121b.
[0063] In addition, in one embodiment, the elastic conductive layer 121b can be composed of a composite of an elastic substrate and conductive fillers. This material can maintain a stable conductivity under conditions such as stretching, bending or other deformations. Therefore, the elastic conductive layer 121b in the embodiment of the present application is a material with both elasticity and conductivity, and can maintain good electrical conductivity when deformed.
[0064] Among them, regarding the above-mentioned elastic substrate, it can be polyurethane, rubber or silica gel.
[0065] In addition, regarding the above-mentioned conductive fillers, they can be carbon nanotubes, metal nanowires or graphene.
[0066] In one embodiment, the spring 122 includes a first spring and a second spring. The diameter of the first spring is smaller than that of the second spring. The first spring is nested inside the second spring. Both the first spring and the second spring are in contact with the needle 121.
[0067] Specifically, in the embodiment of the present application, by simultaneously providing the first spring and the second spring, the contact force between the needle 121 and the contact member 220 can be ensured.
[0068] In one embodiment, the pin 120 includes a first pin and a second pin. The size of the first pin is larger than that of the second pin. The current transmitted by the first pin is greater than the current transmitted by the second pin.
[0069] Specifically, the coexistence of large and small PIN pins in the connector is a design strategy to meet different electrical and mechanical performance requirements. The large PIN pin, i.e., the first pin, is suitable for applications with high current and high mechanical strength, while the small PIN pin, i.e., the second pin, is used for high-precision, low-current signal transmission. Through reasonable design, high performance, high reliability, and high compatibility of the connector can be achieved.
[0070] In one embodiment, the pin 120 and the contact member 220 are made of a corrosion-resistant conductive material.
[0071] Specifically, the pin 120 and the contact member 220 can be made of aluminum, titanium, their alloys, or other materials.
[0072] It should be understood that in the present application, "at least one (item)" means one or more, and "a plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and both A and B exist simultaneously. Here, A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (one) of the following" or its similar expression refers to any combination of these items, including any combination of single item (one) or plural items (ones). For example, at least one (one) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.
