Description

Technical Field

[0001] This application relates to the technical field of electrical connection devices, and more particularly to a socket and connector. Background Technology

[0002] In the field of electronic device connection technology, connectors, as key components for achieving electrical connections, directly affect the safety and reliability of the entire system. Existing connector sockets or plugs, in their structural design, arrange different types of pins within the same space.

Although the flowcharts describe the operations (or steps) as sequential processes, many of these operations can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it may also have additional steps not included in the figures. The process may correspond to a method, function, procedure, subroutine, subroutine, etc.

[0042] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0043] like Figures 1 to 5 As shown, this embodiment provides a socket, including a base 1, a first current pin 2, a second current pin 3, and a signal pin 4. The charge of the first current pin 2 is opposite to that of the second current pin 3, that is, the current flows in opposite directions in the first current pin 2 and the second current pin 3. The base 1 is an insulator, and the base 1 is made of corrosion-resistant material to ensure the stability of the connection and its service life.

[0044] The base 1 is provided with a first needle groove 101, a second needle groove 102, a third needle groove 103, a first dividing groove 104, and a second dividing groove 105. The first needle groove 101, the second needle groove 102, the third needle groove 103, the first dividing groove 104, and the second dividing groove 105 are formed on the same outer side surface of the base 1. The first needle groove 101, the second needle groove 102, and the third needle groove 103 are arranged sequentially at intervals.

[0045] A first current pin 2 is mounted on the base 1 and has a first insertion portion 201 located within a first pin slot 101. The first insertion portion 201 is for insertion into a socket of a first terminal of the plug. A second current pin 3 is mounted on the base 1 and has a second insertion portion 301 located within a second pin slot 102. The second insertion portion 301 is for insertion into a socket of a second terminal of the plug. A signal pin 4 is mounted on the base 1 and has a third insertion portion 401 located within a third pin slot 103. The third insertion portion 401 is for insertion into a socket of a signal terminal of the plug.

[0046] The first dividing groove 104 is located between the first pin groove 101 and the second pin groove 102, and the second dividing groove 105 is located between the second pin groove 102 and the third pin groove 103. This increases the creepage distance between the first current pin 2 and the second current pin 3, and between the second current pin 3 and the signal pin 4, thereby improving the insulation strength of the socket, reducing the possibility of creepage, reducing the occurrence of electrical faults in the socket, and improving the overall safety and reliability of the socket.

[0047] Furthermore, both the first insertion portion 201 of the first current pin 2 and the second insertion portion 301 of the second current pin 3 are cylindrical, with the diameters of both portions being greater than or equal to 8 mm. This embodiment uses an example where both the diameters of the first insertion portion 201 and the second insertion portion 301 are 8 mm, which can satisfy the requirement of transmitting 300A current. Under 300A current, the temperature rise of the socket can be controlled within 50K, satisfying charging within a wider voltage range. By using multiple 8 mm first current pins 2 connected in parallel as the positive terminal and multiple 8 mm second current pins 3 connected in parallel as the negative terminal, high-power fast charging with 300A current connected in parallel at both the positive and negative terminals can be achieved.

[0048] The socket of this application has excellent temperature control and can be used with both air-cooled and liquid-cooled charging modules, and is compatible with various mounting panels. The socket of this application can meet the requirements of charging modules with a power of 60 kW and above. The 60 kW charging module connector is a key component for new energy vehicle charging piles and can meet high-power charging needs. The socket of this application also improves charging efficiency, reduces charging time, and better meets the effective usage time of new energy vehicles.

[0049] In one embodiment, the base 1 includes a housing 106 and a fastener 107 that is mounted on the housing 106 and together with the housing 106 to form a receiving cavity 108.

[0050] The fixing member 107 is provided with a first pinhole 109, a second pinhole 110, and a third pinhole 111. The first pinhole 109, second pinhole 110, and third pinhole 111 are arranged sequentially at intervals and all communicate with the receiving cavity 108. The receiving cavity 108 is provided with multiple partition plates, which divide the receiving cavity 108 into multiple sub-cavities. Each first pinhole 109, each second pinhole 110, and each third pinhole 111 corresponds to a different sub-cavity, improving safety. The first current pin 2 also has a first wiring portion 202, the second current pin 3 also has a second wiring portion 302, and the signal pin 4 also has a third wiring portion 402.

One end of the second wiring portion 302 is located inside the receiving cavity 108 and electrically connected to the second plug portion 301. The other end of the second wiring portion 302 extends through the second pin hole 110 to the outside of the housing 106. One end of the third wiring portion 402 is located inside the receiving cavity 108 and electrically connected to the third plug portion 401. The other end of the third wiring portion 402 extends through the third pin hole 111 to the outside of the housing 106, facilitating wiring.

[0052] Optionally, the first current pin 2, the second current pin 3, and the signal pin 4 are all L-shaped. The first wiring portion 202 is perpendicular to the first plug portion 201, the second wiring portion 302 is perpendicular to the second plug portion 301, and the third wiring portion 402 is perpendicular to the third plug portion 401. The first wiring portion 202 is snapped into the first plug portion 201, the second wiring portion 302 is snapped into the second plug portion 301, and the signal pin 4 is integrally formed.

[0053] The fastener 107 includes a first plate 112 and a second plate 113. The first plate 112 and the second plate 113 are connected and perpendicular to each other. The second pinhole 110 and the third pinhole 111, and the first pinhole 109, the second pinhole 110, and the third pinhole 111 are all formed in the first plate 112. The fastener 107 is divided into the first plate 112 and the second plate 113 by bending the plate 90 degrees, which facilitates the fastener 107 to be soldered onto the PCB circuit board. It can realize wave soldering for assembly line soldering process, so that the first wiring part 202, the second wiring part 302, and the third wiring part 402 are electrically connected to the PCB circuit board, saving the overall assembly time of the connector.

[0054] In one embodiment, the base 1 has a first outer side 114 and a second outer side 115 that are opposite to each other. The first outer side 114 is provided with a first positioning boss 116, and the second outer side 115 is provided with a second positioning boss 117, which facilitates the installation of locking plate terminals.

[0055] The base 1 structure of this application can be serialized, so that the installation form of the socket is consistent, which facilitates maintenance and upgrades.

[0056] Optionally, the inner wall of the first pin slot 101 is provided with a first anti-mistake groove 118 for engaging with the first anti-mistake protrusion of the plug, and the inner wall of the second pin slot 102 is provided with a second anti-mistake groove 119 for engaging with the second anti-mistake protrusion of the plug, so as to force the socket to be plugged into the plug in the correct direction, prevent mis-plugging, and avoid damage to the equipment or circuit failure caused by plugging into the wrong power source.

[0057] Furthermore, the signal pins 4 are arranged in a parallel array of nine. These nine signal pins 4 control multiple functions such as CAN+, CAN-, high level, and low level, providing multiple protections for the effective operation of the connector's charging system.

[0058] Optionally, the first current pin 2 has two pins spaced apart, and the second current pin 3 has two pins spaced apart, which improves the current carrying capacity and heat dissipation performance, ensures signal integrity, and improves the reliability of the socket during insertion and removal.

[0059] In one embodiment, the first current pin 2 is the positive pin, and the second current pin 3 is the negative pin. The negative pin is closer to the signal pin 4 than the positive pin. The proximity of the negative pin to the signal pin 4 can form effective electromagnetic shielding, reducing the interference of positive current on signal transmission. At the same time, the proximity of the negative pin to the signal pin can also optimize the current loop path and reduce impedance fluctuations.

[0060] This embodiment also provides a connector, including a plug and a socket as described in any of the above embodiments. The plug and socket are inserted to complete the electrical connection and enable the transmission of current and signals.

Alternatively, the component in any of the embodiments described above could be the plug, in which case the other component of the connector would be the socket.

[0062] The technical principles of this application have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this application without inventive effort, and these embodiments will all fall within the scope of protection of this application.
