Abstract
The invention relates to a locking assembly for connectors. The locking assembly comprises a locking member body. The locking member body is fixedly installed on a corresponding plug through a fixing structure when used. A push plate is assembled on the locking member body along the front and back direction in a guided moving manner. An anti-separation member is disposed in front of the push plate on the locking member body and is in retaining cooperation with an anti-separation groove on a locking reed on a socket when the plug and the corresponding adaptive socket are plugged in place so as to prevent the plug from being separated from the socket in the plugging direction. The front end of the push plate is provided with a pushing portion used for pushing the locking reed to be outwardly expanded, when the pushing plate moves forwardly, so as to prevent the anti-separation member from being separated from the anti-separation groove. A reset spring is arranged between the push plate and the locking member body and enables the pushing portion to be far away from the locking reed. The locking assembly for connectors may prevent the plug of a connector from being separated from the socket.
Description
Technical field
The present invention relates to electric connector field, relate in particular to connector latch assembly.
Background technology
Existing differential connector as disclosed in Chinese patent literature CN101335406A " differential pair and shielding sheet integral type dual shielding electric connector ", this electric connector comprises that front end is the plug and socket of inserted terminal, wherein plug comprises the plug contact of pin insulator and upper assembling thereof, the tail end of plug contact is electrically connected with difference cable differential lines pair, and socket comprises socket insulator and upper assembling thereof and socket contact plug contact adaptation.When needs signal transmits, the inserted terminal of plug and the inserted terminal of socket are pegged graft, plug contact contacts and is electrically connected with socket contact, the problem that existing this differential connector exists is: corresponding locking mechanism is not set on plug and socket, coupling mechanism force when plug, socket are pegged graft is provided by the frictional force of plug contact and socket contact completely, so not only causes and easily occurs plug, the problem that it is not firm and loosening that socket is pegged graft; And the wearing and tearing of plug contact and socket contact are comparatively serious, the useful life of plug contact and socket contact is shorter.
Summary of the invention
