Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a connector and an electronic equipment. Background Art

[0002] In the use scenarios of electronic products, especially laptops, they are easily disturbed by static electricity in life. In order to improve user experience and reduce customer complaints, laptops will undergo electrostatic testing during the research and development process. However, laptops often fail during electrostatic testing and need to be rectified.

[0003] The USB-A connector is a traditional USB host port design and is a USB interface on a computer motherboard. To prevent static energy from entering the motherboard from the USB-A connector and affecting the product's functions during the use of a laptop, engineers will perform electrostatic protection near the connector on the motherboard end. There are mainly the following methods: First, add transient voltage suppressors (TVS) to the circuit to prevent static electricity from interfering with the internal circuit; second, add a capacitor to the ground to the circuit; third, add a series resistor to the signal to prevent static current from interfering with the internal circuit; fourth, add a TVS, a capacitor to the ground, and a series resistor to the circuit at the same time to protect the internal circuit.

[0004] However, the above method has strict requirements on the setting of TVS. In the actual layout and wiring process, the TVS cannot be placed as required due to insufficient space on the motherboard or other uncontrollable factors, thus affecting the protection effect of the TVS; the protection effect of the ground capacitor against electrostatic interference is limited, and the protection effect for relatively high electrostatic current is poor; adding series resistance to the signal has great limitations, and too large a series resistance value will affect the signal quality and interface function; adding TVS, ground capacitor and series resistance to the circuit at the same time will take up more space on the motherboard, make wiring difficult, have too much impact on signal quality, and have high cost.

[0015] In one possible implementation manner, the connection structure further includes a shell, and the conductive structure is disposed on the shell.

[0016] In the present disclosure, since the connector includes multiple pairs of tip structures, the first tip in the tip structure is arranged on the pin, and the second tip is arranged on the shell, the first tip and the second tip are arranged relative to each other and form a gap, thereby being able to form a tip discharge effect.

[0026] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0027] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 4As shown, a connector of an exemplary embodiment of the present disclosure includes a housing 1 and a main body 2 placed in the housing 1, the main body 2 includes a plurality of conductive terminals 21 and a plurality of pins 22, and the connector further includes a plurality of pairs of tip structures 3, each pair of tip structures 3 includes a first tip 31 and a second tip 32, the first tip 31 is disposed on the pin 22, and the second tip 32 is disposed in the housing 1. The first tip 31 and the second tip 32 are disposed opposite to each other, and a gap 310 is provided between the first tip 31 and the second tip 32.

[0029] In this embodiment, the connector is specifically a USB-A type connector, by setting a first tip 31 on the pin 22, setting a second tip 32 on the housing 1, and the first tip 31 is opposite to the second tip 32 and has a gap 310. When the external static electricity flows to the pin 22, the static electricity will break through the air gap 310 between the first tip 31 and the second tip 32, forming an air ionization discharge path, and the static electricity will lead the static electricity to the housing 1 of the connector through the ionization discharge path, and finally discharge to the ground. When the static charge is completely released, there is no large voltage to maintain a high electric field strength, and the air in the gap 310 cannot continue to ionize, and the tip discharge ends, thereby achieving the purpose of electrostatic protection. As a result, the connector can directly lead the static electricity to the ground, avoid the static electricity from affecting the relevant circuits inside the electronic device, and improve the electrostatic protection effect; the air is discharged after ionization, and there is no limit on the size of static electricity, and the electrostatic resistance is strong; the protection devices such as TVS are reduced, the layout and wiring of the motherboard are simplified, and the space utilization rate of the motherboard is increased; the structure is simple, and the efficiency is improved compared with the existing electrostatic protection method, saving labor costs.

[0030] In one embodiment, the first tip 31 is in a cone or pyramid shape.

[0031] In one embodiment, the second tip 32 is in a cone or pyramid shape.

[0032] In this embodiment, the first tip 31 and the second tip 32 are both in a shape with a sharp corner and capable of generating tip discharge, and can be in a shape including but not limited to a cone or a pyramid. The manufacturing method of the first tip 31 and the second tip 32 can be to process the tip by grinding or laser engraving; or, to cut a reserved space at the position where the first tip 31 and the second tip 32 are welded, and then the first tip 31 and the second tip 32 are welded at the corresponding reserved position.

[0033] In one embodiment, the gap 310 has a value ranging from 0 to 0.33 mm.

[0034] In this embodiment, according to the formula:

[0035]

[0036] In the above formula, E is the electric field strength that can cause air breakdown, and its specific value is 3×10 6 V / m, S is the discharge distance, and U is the electrostatic test voltage of the USB-A connector, which is usually 1kV to 8kV. Therefore, according to the above formula, when the electrostatic test voltage is 1kV, the discharge distance is 0.33mm, that is, when the electrostatic energy is 1kV, the distance between the first tip 31 and the second tip 32 is less than 0.33mm to generate tip discharge. It can be understood that 0.33mm is not an absolute 0.33mm, and there can be a small deviation within the tolerance range.

[0037] In one embodiment, the first tip 31 has a first tip portion 311 , and the second tip 32 has a second tip portion 321 . In each pair of tip structures 3 , the connection line between the first tip portion 311 and the second tip portion 321 meets the vertical condition with the pin 22 .

[0038] In this embodiment, the connection line between the first pointed portion 311 and the second pointed portion 321 meets the vertical condition with the lead 22 , thereby ensuring that the first pointed end 31 and the second pointed end 32 are opposite to each other.

[0039] In one embodiment, the connector further includes an air layer, and the air layer fills the gap 310 .

[0040] In this embodiment, the gap 310 between the first tip 31 and the second tip 32 is filled with air. When external static electricity flows to the pin 22, the static electricity will break through the air gap 310 between the first tip 31 and the second tip 32, forming an air ionization discharge path. The static electricity is drawn to the connector housing 1 through the ionization discharge path and finally discharged to the ground.

[0041] In one embodiment, the first tip 31 and the second tip 32 are made of a conductive metal material.

[0042] In this embodiment, the first tip 31 and the second tip 32 are both made of conductive metal, which may include but is not limited to aluminum, copper or alloy.

[0043] Reference Figure 5 As shown, the present disclosure also provides an electronic device, including a connection structure, the connection structure having multiple ports 4, at least one of the above ports 4 is connected to a connector as in any of the above-mentioned embodiments, and a conductive structure 5 is provided at each port 4, and the conductive structure 5 is in contact with a shell 1 of the connector.

[0044] In this embodiment, the electronic device is usually a laptop computer, and the conductive structure 5 can be specifically conductive foam, or a spring point protruding from the laptop computer C shell (referring to the shell 1 around the laptop computer keyboard and touchpad), and the conductive foam and the spring point are both universally designed for electromagnetic compatibility. In this disclosure, the conductive structure 5 is taken as an example of conductive foam, and conductive foam is provided at each port 4.

[0045] In one possible implementation manner, one of the ports 4 is further connected to an interface 6, and the interface 6 is used to electrically connect to a socket (not shown in the figure) outside the electronic device.

[0046] In this embodiment, the interface 6 can be a charging port, an HDMI port, a Type-C port, or a USB-A port, etc., and one of the multiple ports 4 can be plugged into one of the above interfaces 6. For example, if one port 4 is connected to the connector in the present application, and another port 4 is connected to the charging port, the path of static electricity after it is generated is to first pass through the housing 1 of the connector. Since the conductive foam is in contact with the housing 1 of the connector, it reaches the conductive foam from the housing 1 of the connector. Since the conductive foam is set on the C shell, the static electricity passes through the C shell to the conductive foam at the port 4 connected to the charging port, and then passes through the charging port to the power adapter and its connecting line, and finally reaches the indoor socket ground. If one port 4 is connected to the connector in the present application and the other port 4 is connected to an HDMI interface or a Type-C interface, the path of static electricity after it is generated is to first pass through the connector shell 1. Since the conductive foam is in contact with the connector shell 1, it reaches the conductive foam from the connector shell 1. Since the conductive foam is arranged on the C shell, the static electricity passes through the C shell to the conductive foam at the port 4 connected to the HDMI interface or the Type-C interface, and then is transmitted to the display through the HDMI interface or the Type-C interface. The display is connected to the indoor socket ground through its power cord, thereby completing the discharge.

[0047] In one embodiment, the connection structure further includes a shell 7 , and the conductive structure 5 is disposed on the shell 7 .

[0048] In this embodiment, the housing 7 is a C-shell in a laptop computer (referring to the housing 1 around the keyboard and touch pad of the laptop computer), and the conductive foam is arranged on the C-shell.
