Description

Technical Field

[0002] Contact pins are a crucial structural component of plug-in sockets. They connect the internal contact pins of a plug to the pins in the plug, enabling signal or power transmission. Therefore, the stability of contact between the contact pins and the pins is a crucial indicator of plug-in socket quality. With the increasing power density and signal quality of today's charging and power-consuming devices, the power requirements for sockets and signal transmission quality are also increasing.

[0003] The spring clip is a crucial structural component of the contact pin. It's elastic, and the contact at its end connects to the plug pin. However, current spring clips typically use separate spring clips to connect to the plug pin. This structural design can result in low current output. Since the socket contact pin and the plug pin rely on a separate spring clip, poor contact can easily occur after frequent plugging and unplugging. This causes the contact points to heat up, impacting the stability of the power signal connection.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components.

[0035] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0036] The utility model provides Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The dual-contact contact pin shown is an important structural and functional component in a socket. It is used to mate with the male pin 7 of a plug to achieve an electrical connection between the female socket and the male plug. The dual-contact contact pin of this embodiment comprises a wiring segment 1, at least one snap-on segment 2, and at least one first contact spring 3. The wiring segment 1 is used to connect to the socket wiring harness to achieve an electrical connection. The snap-on segment 2 is connected to one end of the wiring segment 1 and is used to snap into the socket body 6. The first contact spring 3 is disposed on the snap-on segment 2 at the end away from the wiring segment 1. A second contact spring 4 is disposed on the first contact spring 3. The first contact spring 3 and the second contact spring 4 are respectively provided with a first bend 31 and a second bend 41, forming two contact points. The two contact points are directly frictionally connected to the pin 7 on the plug. The first bend 31 and the second bend 41 are used to contact the plug pin 7. When the plug is plugged into the socket, the plug pin 7 contacts the two contact points on the socket. The elastic effect of the first contact spring 3 and the second contact spring 4 can provide a buffering effect when the two contact points are connected to the pins 7 on the plug, and the connection is stable.

[0037] It should be noted that the spring clip is a crucial structural component of the contact pin. It possesses elasticity, and the contact at its end is used to connect with pin 7 on the plug. However, current spring clips typically utilize a separate spring clip for connection to pin 7 on the plug. This structural design can easily result in low current output. Since the connection between the socket contact pin and pin 7 relies on a separate spring clip, poor contact between the contacts can occur after prolonged and frequent plugging and unplugging. This can cause the contact points to heat up, impacting the stability of the power signal connection.

[0038] The present invention forms dual contacts by means of the first bent portion 31 and the second bent portion 41. Compared to conventional single-contact designs, if one of the dual contacts fails, the other contact can continue to operate. Therefore, the dual-contact design provides a more stable connection with the plug pin 7, enables high current transmission, and effectively reduces heating during operation of the socket body 6.

[0039] Further, such as Figure 1 、 Figure 4 and Figure 5 As shown, the second spring contact piece 4 extends toward the connection segment 1. When the plug is inserted into the socket body 6, the head of the pin 7 connects with the second spring contact piece 4 and can be inserted along the extension direction of the second spring contact piece 4. This prevents the end of the second spring contact piece 4 from colliding with the front end of the pin 7 and causing bending.

[0040] In other embodiments, Figure 6 and Figure 7 As shown, the second contact spring 4 extends away from the wiring segment 1. That is, the extension direction of the first contact spring 3 is the same as that of the second contact spring 4. It should be noted that the end of the second contact spring 4 must be lower than the height of the contact surface of the first contact spring 3 to prevent the end of the second contact spring 4 from colliding with the pin 7 and bending.

[0041] Further, such as Figure 4 and Figure 6 As shown, an arc-shaped buffer portion 5 is provided between the clamping segment 2 and the first contact elastic piece 3 , and the arc-shaped buffer portion 5 is used to buffer the stress between the clamping segment 2 and the first contact elastic piece 3 .

[0042] Furthermore, at least one of the first contact spring 3 and the second contact spring 4 is provided with a gold-plated layer.

[0043] As you can understand, gold is an excellent conductive material, and plating binding posts with gold significantly improves their conductivity. This helps reduce resistive losses during current transmission, ensuring stable and efficient current flow through the binding posts, thereby improving the overall performance and efficiency of the circuit. Therefore, gold plating on binding posts enhances conductivity. Furthermore, gold plating on binding posts prevents oxidation, improving reliability. This makes the binding posts more durable and reduces the likelihood of failures caused by poor contact or oxidation.

[0044] Further, such as Figure 1 and Figure 4 As shown, the wiring segment 1, the clamping segment 2, the first contact spring 3 and the second contact spring 4 are integrally formed.

[0045] Furthermore, the wiring segment 1 , the clamping segment 2 , the first contact spring 3 and the second contact spring 4 are all made of metal copper.

[0046] Furthermore, a gold layer is provided at least on the outer corner of the first bend portion 31 and the outer corner of the second bend portion 41. Providing the gold layer on the outer corners of the first bend portion 31 and the outer corners of the second bend portion 41 eliminates the need for gold plating on other structural parts, effectively reducing the area of ​​the gold plating and lowering costs.

[0047] Understandably, copper has one of the highest electrical conductivity ratings among metals. At 20°C, copper's conductivity is approximately 59.6 × 10⁶ S / m. This means copper can transmit current with low resistance, reducing energy loss during transmission.

[0048] Furthermore, copper metal has good stability and ductility and can be drawn into thin wires or pressed into thin sheets, which enables the wiring section 1, the clamping section 2, the first contact spring 3 and the second contact spring 4 to be conveniently stamped into an integral body.

[0049] Further, such as Figure 1 and Figure 4 As shown, the engaging section 2 is provided with a engaging member 21 for engaging with the mounting base 61 within the socket body 6. The engaging member 21 is integrally formed with the engaging section 2. The engaging member 21 secures the dual-contact contact pins of this embodiment within the socket body 6, preventing the socket and plug from becoming loose during repeated insertion and removal cycles.

[0050] Furthermore, a clamping groove 22 is provided on the clamping section 2 , and the clamping groove 22 is used for clamping the mounting base 61 in the socket body 6 .

[0051] like Figure 3 As shown, a second aspect provides a socket, comprising: a socket body 6 and the dual-contact contact pins described in the first aspect. A mounting base 61 is provided within the socket body 6, and the dual-contact contact pins are disposed within the mounting base 61. The socket body 6 (housing) is typically made of a high-temperature-resistant, flame-retardant plastic material. With the support of high-power, highly conductive socket pins, the socket can ensure safety and reliability during use.

[0052] To sum up, the utility model provides a double-contact contact pin and socket. The utility model forms a double contact through the first bending portion 31 and the second bending portion 41. The double contact can be stably connected to the plug pin 7, which can achieve large current output and effectively reduce the heat problem during operation.

[0053] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
