Description

Technical Field

[0001] The utility model relates to the field of automobile connectors, in particular to a seamless cylindrical electric connector terminal. Background Art

[0002] Terminals are components that transmit current and signals between multiple electronic devices, such as terminals for charging guns. The terminals are usually cylindrical and are generally formed by turning metal bars. The processing time is long and the cost is high. After the initial columnar shape is formed, it is necessary to manually fix the insulating pads and other components on the terminals. Since the insulating pads are made of materials such as silicone, they are prone to cracking or even falling off after being bonded with ordinary adhesives for a period of time.

[0004] The contact portion of the cylindrical male terminal of the above patented technical solution is formed by stamping and bending. There is a gap between the contact portions of the male terminal formed by stamping and bending, which makes the overall contact surface of the cylindrical male terminal irregular, and it is easy to have poor contact when the male and female are plugged together; therefore, it is necessary to provide a male terminal with a regular cylindrical overall contact surface to solve the above problems. Utility Model Content

[0005] The purpose of the present application is to provide a seamless cylindrical electrical connector terminal to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] It comprises a main body, on which a crimping area and a cylindrical male end contact portion are respectively formed, and is characterized in that: the cylindrical male end contact portion is formed in one piece by stretching.

[0008] Preferably, a fixing column is further included, wherein one section of the cylindrical male end contact portion is embedded in one section of the fixing column, and another section of the fixing column is embedded in another section of the male end contact portion.

[0009] Preferably, a sealing plug and an insulating head are respectively provided at both ends of the cylindrical male end contact portion, and the sealing plug and the insulating head are connected via the fixing column.

[0010] Preferably, the crimping area is V-shaped or U-shaped.

[0011] Preferably, the cylindrical male end contact portion is hollow.

[0012] Preferably, the fixing column is a plastic column.

[0013] Preferably, the sealing plug is a waterproof ring.

[0014] Preferably, the main body is composed of multiple groups.

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] The cylindrical male end contact portion of the present invention is seamlessly stretched and integrally formed, and the contact surface of the formed cylindrical male end is more rounded and more regular. When the male and female connectors are plugged in, the contact is more stable and the current synchronization is also more stable. BRIEF DESCRIPTION OF THE DRAWINGS
