Abstract
Description
Technical Field
[0001] This utility model relates to the field of push-button switch technology, and in particular to an electronic connector and plug-in connector that supports plugging and unplugging. Background Technology
[0002] Keyboard push-button switches are widely used input components in electronic devices, such as keyboards. They are typically electrically connected to a switch circuit control board via a pluggable connector to transmit key input signals. In the prior art, the connector of a keyboard push-button switch usually includes a socket for insertion, on which two opposing contacts are provided for forming an electrical connection with the pins of the push-button switch.
[0003] In this type of two-point contact structure, after the conductive pin is inserted, electrical signals are transmitted by clamping it between the contacts on both sides. However, since the electrical connection relies solely on the clamping of two contacts, problems such as oxidation, dirt, or mechanical deformation on the surface of the conductive pin may prevent the two contacts from making effective contact with the pin, resulting in poor contact and affecting the transmission of electrical signals. Furthermore, with prolonged use or repeated insertions and removals, the elasticity of the contacts may weaken, reducing contact pressure and further exacerbating the risk of poor contact. In addition, the stability of the two-point contact connection is difficult to guarantee under the influence of external environmental factors such as vibration and impact, which may lead to button trigger failure or signal transmission interruption.
[0004] As the performance of electronic devices continues to improve, higher demands are placed on the stability and reliability of signal transmission. Existing two-point contact structures have poor fault tolerance and are difficult to adapt to high-frequency, high-precision application scenarios. Utility Model Content
[0005] The purpose of this invention is to provide an electronic connector and plug-in type connector that effectively improves contact reliability and signal transmission stability by supporting plugging and unplugging.
[0006] To achieve the above objectives, this utility model provides an electronic connector that supports plugging and unplugging, comprising a body, the body including a first connection end and a second connection end for electrical connection with different objects, wherein an electrical signal can flow between the first connection end and the second connection end, the first connection end including a first contact portion, a second contact portion and a third contact portion having conductive properties, the first contact portion and the second contact portion being disposed opposite to each other, and forming a plugging and unplugging channel between the first contact portion and the second contact portion for the conductive pin of the connected object to be inserted or pulled out in a tight fit manner; the third contact portion is located in front of the plugging and unplugging channel, and abuts against the third contact portion after the conductive pin is inserted into the plugging and unplugging channel and passes through the plugging and unplugging channel.
[0007] Preferably, the first connecting end is provided with a first arm and a second arm opposite to each other. One end of the first arm is provided with a first spring piece that is curved and can undergo elastic deformation. The same end of the second arm as the first arm is provided with a second spring piece that is curved and can undergo elastic deformation. The closest parts of the first spring piece and the second spring piece form the first contact part and the second contact part.
[0008] Preferably, the end of the first arm away from the first spring is provided with a third spring extending toward the central axis of the insertion channel, the third spring being elastically deformable, and the tail end of the third spring forming the third contact portion.
[0009] Preferably, the third spring is integrally formed with the first spring.
[0010] Preferably, it also includes a fourth contact portion located in front of the insertion channel and opposite to the second contact portion. When the conductive pin is inserted into the insertion channel and passes through the insertion channel, the opposite sides of the conductive pin abut against the third contact portion and the fourth contact portion, respectively.
[0011] Preferably, the first connecting end is provided with a first arm and a second arm opposite to each other. One end of the first arm is provided with a first spring piece that is curved and elastically deformable. The same end of the second arm as the first arm is provided with a second spring piece that is curved and elastically deformable. The closest parts of the first spring piece and the second spring piece form the first contact portion and the second contact portion, respectively. The end of the first arm away from the first spring piece is provided with a third spring piece that extends toward the central axis of the insertion channel. The third spring piece is elastically deformable, and its tail end forms the third contact portion. The end of the second arm away from the second spring piece is provided with a fourth spring piece that extends toward the central axis of the insertion channel. The fourth spring piece is elastically deformable, and its tail end forms the fourth contact portion.
[0012] Preferably, the tail ends of the third spring and the fourth spring are located on both sides of the central axis of the insertion and removal channel.
[0013] Preferably, the main body further includes a transition section, through which the first connecting end and the second connecting end are connected.
[0014] This utility model also provides a plug-in connector, which includes a base, and an electronic connector as described above is respectively embedded in both ends of the base. The two ends of the base are respectively provided with plug-in holes opposite to the plug-in channels of the two electronic connectors.
[0015] Preferably, the socket is used to receive the pins of the push-button switch, and the second connection terminal is used to connect to the control circuit of the push-button switch.
[0016] Compared with existing technologies, the electronic connector disclosed in this utility model has an additional third contact portion in addition to the first and second contact portions forming the insertion / removal channel. This third contact portion forms a stable triangular structure with the first and second contact portions. Thus, even if the two contact portions on either side of the insertion / removal channel experience poor contact due to oxidation, dirt, or mechanical deformation, the third contact portion can still maintain effective contact with the conductive pins of the connected object, thereby ensuring normal signal transmission. This design significantly improves the connector's fault tolerance and contact reliability. Secondly, the three-point contact forms a multi-path conductive design, effectively reducing contact resistance fluctuations and enhancing resistance to external vibrations and impacts. Even in complex operating environments, stable signal transmission can still be achieved, avoiding signal interruption or errors. Furthermore, by increasing the contact point distribution, the mechanical stress borne by a single contact portion is dispersed, reducing contact wear and elastic fatigue. Under long-term use or frequent insertion / removal, structural stability and durability are significantly improved. Attached Figure Description

[0023] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0024] like Figures 1 to 3This embodiment discloses a pluggable electronic connector 100, meaning that the electronic connector 100 can establish a connection with other devices through plugging, and the pins of the connected devices can be unplugged from the electronic connector 100. The electronic connector 100 can be used for push-button switches or other electronic control switching devices.
[0025] The electronic connector 100 includes a body, which includes a first connection terminal D1 and a second connection terminal D2 for electrical connection with different objects, respectively, and electrical signals can flow between the first connection terminal D1 and the second connection terminal D2. For example, the first connection terminal D1 is connected to a push-button switch, and the second connection terminal D2 is connected to the control circuit of the push-button switch.
[0026] The first connection terminal D1 includes a first contact J1, a second contact J2, and a third contact J3, all of which are conductive. Each of these three contacts can transmit received signals to the second connection terminal D2.
[0027] The first contact portion J1 and the second contact portion J2 are disposed opposite to each other, and a plug-in channel 1 is formed between the first contact portion J1 and the second contact portion J2, which allows the conductive pin of the connected object to be inserted or removed in a tight fit manner. The third contact portion J3 is located in front of the plug-in channel 1, and abuts against the third contact portion J3 after the conductive pin is inserted into the plug-in channel 1 and passes through the plug-in channel 1.
[0028] In this embodiment, the electronic connector 100 is additionally provided with a third contact portion J3 in addition to the first contact portion J1 and the second contact portion J2 forming the insertion channel 1. The third contact portion J3 forms a stable triangular structure with the first contact portion J1 and the second contact portion J2. In this way, even if the two contact portions on both sides of the insertion channel 1 become poorly contacted due to oxidation, dirt, or mechanical deformation, the third contact portion J3 can still maintain effective contact with the conductive pin of the connected object, thereby ensuring the normal transmission of electrical signals.
[0029] This design significantly improves the fault tolerance and contact reliability of connector 100. Secondly, the three-point contact creates a multi-path conductive design, effectively reducing contact resistance fluctuations and enhancing immunity to external vibrations and shocks. Even in complex operating environments, stable signal transmission can be achieved, avoiding signal interruptions or errors.
[0030] Furthermore, by increasing the distribution of contact points, the mechanical stress borne by individual contact parts is dispersed, reducing contact wear and elastic fatigue. This significantly improves structural stability and durability during long-term use or frequent insertion and removal.
[0031] On the other hand, the main body also includes a transition section D3, through which the first connecting end D1 and the second connecting end D2 are connected.
[0032] On the other hand, the first connecting end D1 is provided with a first arm 2 and a second arm 3. One end of the first arm 2 is provided with a first spring piece 20 that is curved and can be elastically deformed. The same end of the second arm 3 as the first arm 2 is provided with a second spring piece 30 that is curved and can be elastically deformed. The closest parts of the first spring piece 20 and the second spring piece 30 form a first contact part J1 and a second contact part J2.
[0033] In this embodiment, the first spring 20 is integrally formed with the first support arm 2, and the second spring 30 is integrally formed with the second support arm 3. Since the first spring 20 and the second spring 30 can undergo elastic deformation, the width of the insertion channel 1 located between the first spring 20 and the second spring 30 can undergo elastic deformation, thereby allowing the conductive pin to be inserted into the insertion channel 1 in a tight fit manner.
[0034] In addition, a third spring 21 extending toward the central axis of the insertion channel 1 is provided at the end of the first arm 2 away from the first spring 20. The third spring 21 can undergo elastic deformation, and the tail end of the third spring 21 forms a third contact part J3.
[0035] When the conductive pin is inserted and passes through the insertion / removal channel 1, one side of the conductive pin abuts against the tail end of the third spring 21, thereby the third spring 21 applies a resisting force perpendicular to the central axis of the conductive channel to the conductive pin, so that the conductive pin is securely fixed in the insertion / removal channel 1.
[0036] Specifically, the third spring 21 is integrally formed with the first spring 20.
[0037] In another preferred embodiment of this utility model, such as Figure 4 and Figure 5 The electronic connector 100 also includes a fourth contact J4 located in front of the insertion / removal channel 1 and disposed opposite to the second contact J2. Any of the first contact J1, the second contact J2, the third contact J3, and the fourth contact J4 can transmit an electrical signal on the conductive pin to the second connection terminal D2 when it comes into contact with the conductive pin of the connected object.
[0038] When the conductive pin is inserted into and exits through the insertion channel 1, the opposite sides of the conductive pin abut against the third contact J3 and the fourth contact J4, respectively.
[0039] In this embodiment, by setting the third contact part J3, when the conductive pin passes through the insertion channel 1, the front and rear sides of the conductive pin are respectively abutted by the third contact part J3 and the fourth contact part J4, thereby further enhancing the reliability and stability of the connector 100.
[0040] Specifically, the end of the second arm 3 away from the second spring 30 is provided with a fourth spring 31 extending toward the central axis of the insertion channel 1. The fourth spring 31 can undergo elastic deformation, and the tail end of the fourth spring 31 forms a fourth contact part J4.
[0041] The electrical signals received by the first contact part J1 and the third contact part J3 are transmitted to the transition part D3 through the first support arm 2, and then transmitted to the second connection end D2 through the transition part D3.
[0042] The electrical signals received by the second contact part J2 and the fourth contact part J4 are transmitted to the transition part D3 through the second support arm 3, and then transmitted to the second connection end D2 through the transition part D3.
[0043] On the other hand, the tail ends of the third spring 21 and the fourth spring 31 are located on both sides of the central axis of the insertion and removal channel 1.
[0044] In another preferred embodiment of this utility model, such as Figure 6 The paper also discloses a plug-in connector M, which includes a base 4. An electronic connector 100 with the above-mentioned structure is respectively embedded in both ends of the base 4. The two ends of the base 4 are respectively provided with plug-in holes 40 opposite to the plug-in channels 1 of the two electronic connectors 100.
[0045] In this embodiment, the insertion hole 40 is used to receive the pins of the push-button switch, and the second connection terminal D2 is used to connect to the control circuit of the push-button switch. In use, the two pins of the push-button switch are respectively inserted into the insertion / removal channels 1 on the corresponding electronic connector 100 through the two insertion holes 40 on the base 4.
[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
