Description
Technical field
The utility model belongs to electrical device technologies field, and in particular to a kind of pull rod driving mechanism and self-locking plug adapter.
Background technique
The form of the connector of some prior arts, either bolt or jack has been designed for reducing connector from matching
Pair jack or bolt on remove or the easiness that accidentally falls.The known scheme generallyd use in computer equipment be
Bolt or clip are provided on the either side of connector, so that connector remains attached in equipment.However, connecting or pressing from both sides joint screw thread
It is laborious for holding in equipment, is become difficult in most cases since space limits.
To solve this problem, it is known that provide locking mechanism for connector, but user need to operate with by connector from matching
Pair joint assembly on separate.The example of known and successful locked joints describes in British patent GB2383202.
However, causing especially for computer and of this sort electrical equipment to the lasting driving of compact-sized degree
Traditionally surround the diminution of the space envelope of removable connector substantially.
In this way, for example, the PCU type being recently introduced is characterized in that the additional metal tab or handle close to joint location
Hand, for easily being removed from server.Due to the compact of equipment design, the lockable electrical connector in many types is provided
On release fin hinder insertion, and in other circumstances, hinder close to the limited space envelope of connector may
Ask enough and described release control when removing connector.
Typically, space when in the case of being connected to the bolt or jack of electrical equipment pairing, around connector
The reduction of envelope is limited to the region for the distance no more than joint length extended from equipment.Correspondingly, it is possible to, pass through
The problems caused by space for having the connector of longer length body to overcome reduction is provided.In this way, for example clearing away any metal
At the position of fin or handle, unclamping control can be further spaced apart from the interface end of connector.However, the program has in this way
The shortcomings that, the equipment for substantially eliminating more compact design seeks the advantages of space realized reduces.This is because in equipment
And locating for the equipment before wall or other surfaces between will need bigger space, to accommodate greater length of connector.
202949090 U of Chinese patent CN discloses a kind of locking electrical connector, including main body, which has first
End regions, the first end region include one or more electrical contacts, and the electrical contact with complementary joint assembly for connecing
Touching, the main body also have the second end region against the first end region, guide from it against protection, elastic conductor can
It is guided and is extended by the protection, the main body of the connector includes locking mechanism, so that when in use, the connector can be optional
Selecting property is releasably secured on complementary joint assembly, and the connector includes unclamping control, i.e. pull rod, can be operated to act on
On locking mechanism and allow to unclamp the connector from complementary joint assembly, wherein when examining on the length direction in the connector
When worry, the release control can operate at the position of the first end of the connector more farther than the second end.
Although above-mentioned patented product avoids the problem of interfering with other component to a certain extent, pull rod is by position
It is driven in the pull ring of tail end, when being inserted into plug, while operating pull ring release lock sheet and not meeting operating habit, than less
It is convenient.Meanwhile such such problems is also faced on the device that other have movement.
