Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to an electric connector. Background Art

[0002] Connectors in related technologies, such as Figures 1 to 3 , by combining the terminal group 212 and the fixing part 211 to form a terminal unit 21, and then fixing it to the slot 11 of the base body through assembly. Since the connector usually requires multiple terminal units 21 to be used side by side to form an array contact to provide a denser contact point arrangement, it is necessary to insert multiple terminal units 21 into the corresponding slots 11 one by one. The slot 11 is usually provided with a first fixing structure 12 that is connected and fixed with the second fixing structure on the terminal unit 21. Since each terminal unit 21 is an independent individual, after being independently inserted into the slot 11, the terminal units 21 do not affect each other. If the second fixing structure of a terminal unit 21 is abnormal, the terminal unit 21 cannot be fixed to the slot 11, thereby causing the entire electrical connector to fail. Utility Model Content

In some embodiments, only a portion of the first fixing structure 12 may be connected and fixed to the second fixing structure 2114. Since the terminal assembly 20 is integral, the terminal assembly 20 can be fixed to the base 10 as a whole. In some other embodiments, there may be one second fixing structure 2114 or the number of the second fixing structure 2114 may be less than the number of the terminal assemblies 20 .

[0053] In some embodiments, the second fixing structure 2114 can be a hook, which can be provided at the second end 211b of the fixing member 211. The hook is provided corresponding to and cooperates with the hole of the first fixing structure 12, that is, the hook can be locked into the hole. Of course, it is understood that in other embodiments, when the first fixing structure 12 is a hook, the second fixing structure 2114 can be a slot or a hole.

In some other embodiments, the positioning column 2115 can be set on the second surface 2112, and the positioning hole 2116 can be set on the first surface 2111; when two adjacent terminal units 21 are spliced, the positioning column 2115 on the second surface 2112 of one fixing part 211 can be correspondingly connected to the positioning hole 2116 on the first surface 2111 of the other fixing part 211.

[0055] In some embodiments, the terminal group 212 at least partially extends from the first end 211a, and when the terminal assembly 20 is installed in the base 10, the terminal group 212 can extend from the second opening 16. In some embodiments, the terminal group 212 may include at least one terminal 2120, specifically, five terminals 2120. In other embodiments, each terminal group 212 may include one, two, or three terminals. Each terminal 212 may include a first plug-in portion 2121 and a second plug-in portion 2122.
