Wire-to-wire connectors, which include both wire-to-cable and cable-to-cable types, are defined by the permanent connection of two individual wires or corresponding conductors of two cables. These connectors are widely used in automotive, communications, consumer electronics, data processing, industrial machinery, and other fields. Wire-to-wire connectors typically consist of a connector housing, terminal assemblies, and a wire or cable extending into the connector housing.

[0003] In the prior art, ordinary wire-to-wire connector contact terminals all use stamping parts. The contact area between the male and female pins is small after insertion, there is no anti-vibration effect, and the insertion life is short. For some devices that need to be frequently plugged and unplugged, repeated plugging and unplugging can easily damage the terminals, affecting normal use. Secondly, the existing wire-to-wire connectors will be suspended in the chassis after insertion and cannot be fixed. In the event of shaking, the plug and socket may loosen, and the hanging and shaking may also affect the surrounding components, posing a hidden danger in use. Moreover, the suspended connection between the plug and the socket will affect the beauty of the overall internal wiring. In addition, the existing wire-to-wire connectors have poor waterproof effect.

Specifically, the first cavity 2121 is plugged into the insertion portion 1111, and one end of the second terminal 221 located in the second cavity 2122 is electrically connected to the second cable 222. That is, the second cable 222 is welded and fixed to the second connection portion 2212 of the second terminal 221 to form the second terminal assembly 220, and then the second terminal assembly 220 is installed in the installation cavity 212. Then, the second colloid 23 is filled in the second cavity 2122, and the second terminal 221 and the second cable 222 are fixed and the second cavity 2122 is sealed by the second colloid 23. Filling the second cavity 2122 with the second colloid 23 not only makes the installation of the second terminal structure 22 in the mother shell 21 more stable, but also plays a role in sealing and waterproofing, and can block the unused positioning hole 2131.

[0040] See also Figure 3 and Figure 8 and Figure 9 In some optional embodiments, the housing 111 is provided with a first protrusion 1112 extending from the outer periphery of the insertion portion 1111, and a recessed slot 1113 is formed between the insertion portion 1111 and the first protrusion 1112.

When the second terminal piece 221 is inserted into the mating cavity 1211, the outer wall of the mating cavity 1211 can be elastically movable within a certain range through the groove body 1213, so that the second terminal piece 221 can be better inserted into the mating cavity 1211, and the elastically movable outer wall always has a reset tendency, so that the first terminal piece 121 can elastically wrap the second terminal piece 221 more tightly, which can play a shockproof effect and have a good mating effect. In addition, the elastic wrapping can also make the contact area between the first terminal piece 121 and the second terminal piece 221 larger, and the overall assembly effect is better. In this embodiment, the first terminal piece 121 and the second terminal piece 221 use lathe terminals, and the insertion life can reach 1000 times. The terminals of ordinary wire-to-wire connectors 100 are generally stamped parts, and their lifespan is about times. The first terminal piece 121 and the second terminal piece 221 in the present invention, the length of the second terminal inserted into the mating cavity 1211 is between 2.6 mm and 2.8 mm. The structure is more reasonable, the contact area is larger, it can also play an anti-vibration effect, and the plug-in life is longer.
