Abstract
The invention provides a stable type electrical connector comprising a plug and a socket. A plug shell comprises a first conductive wire connecting part and a socket connecting part. The socket connecting part comprises an internal cylinder, an external cylinder, and a fixing sleeve which sleeves outside the external cylinder. The external wall of the internal cylinder is provided with multiple strip-shaped position-limiting plates. The length direction of the position-limiting plates is parallel to the axial direction of the internal cylinder. A socket shell comprises a second conductive wire connecting part and a hollow cylindrical plug connecting part. A stop circle is arranged between the plug connecting part and a socket insulator. The stop circle is formed by multiple stop plates via enclosing. Gaps are reserved between the adjacent stop plates. The position-limiting plates can be clamped in the gaps. The fixing sleeve is externally sleeved by a locking sleeve. The stable type electrical connector is convenient in plugging, close in matching of all structures and great in stability after the plug is plugged in the socket and the plug is not liable to fall. The locking sleeve is used for locking the plug and the socket so that connection stability of the electrical connector can be guaranteed. The required plugging force is relatively low, and a protection structure is arranged so that the plug and the socket are not liable to be damaged and the service life is long.
