Specific embodiment
Hereinafter, for a more detailed description to the utility model with embodiment combination attached drawing.This embodiment is only to this
The description of utility model preferred forms, does not have any restrictions to the scope of the utility model.
As shown in Figures 1 to 5, a kind of socket with terminal screw anti-back structure, including jack body 1, are set to slotting
Seat 1 side of ontology and the protective cover 2 being interlocked with jack body 1, further include the limitation shell for being set to 1 other side of jack body
3, it limits and is equipped with terminal screw ontology 4 and connection copper piece 5,4 one end of terminal screw ontology and company between shell 3 and jack body 1
The threaded connection of copper piece 5 is connect, and is extend into connection copper piece 5, the limitation shell 3 is equipped with and the insertion that connect copper piece 5 and match
Hole 31, and the holding part 6 being hinged with limitation shell 3, the holding part 6 are equipped with twist corresponding with terminal screw ontology 4
Tieholen 61, described tighten are equipped with spring 7 between hole 61 and terminal screw ontology 4, tighten the lock that 61 periphery of hole is equipped with holding spring 7
Spring block 62.
The holding part 6 is equipped with the fixation projection 63 matched with jack body 1 close to 1 one end of jack body.
The snap block 62 is equipped with the groove 621 for placing spring 7, and the opening of groove 621 is equipped with the fixation of holding spring 7
Buckle 622.
Described 4 one end of terminal screw ontology is equipped with extension circle 41, and the diameter of the extension circle 41, which is greater than, tightens the straight of hole 61
Diameter.
Limitation 3 side of shell and jack body 1 are interlocked, and the other side is connected and fixed by screw with jack body 1.
Specific working principle are as follows:
Firstly, 4 one end of terminal screw ontology is connected by screw thread with copper piece 5 is connect, and is extend into connection copper piece 5,
The holding part 6 is overturn to limitation 3 back side of shell, the i.e. one side far from jack body 1；Expose snap block 62；Institute
Fixed card buckle 622 is stated towards the axis direction for tightening hole 61, and is uniformly distributed around its axle center；When 7 one end of spring be rotating it is stubborn
When entering in groove 621, fixed card buckle 622 is passed through by the screw pitch gap of spring 7 itself；Due to the size and spring 7 of groove 621
Size match, therefore, directly to 621 outer pull-off spring 7 of groove when, spring 7 will be fixed 622 holdings of buckle and live；Spring 7
Groove 621 can only could be taken out by reversely rotating；
Further, when groove 621 is fixed in 7 holding of spring, the holding part 6 is overturn, until fixed 63 court of projection
To jack body 1；Limitation shell 3 is equipped with the overturning notch 32 for meeting 6 motion profile of part, and jack body 1 is equipped with and overturning
The limitation item 11 that notch 32 matches, when limiting shell 3 and jack body 1 is connected and fixed, limitation item 11 is inserted into overturning and lacks
In mouth 32, fixed projection 63 is lived in holding；
Further, it is connected and fixed the limitation shell 3 and jack body 1, it is described at this time to tighten hole 61 and terminal screw
The position of ontology 4 is corresponding, and spring 7 encloses 41 surfaces in extension far from 6 one end overhead of holding part；The insertion hole 31 and connection copper
The position of part 5 is corresponding；
Further, one end of circuit connection is inserted into connection copper piece 5 by being inserted into hole 31；
Further, hole 61 is tightened using the insertion of installation tool knife, passes through spring 7, supported to terminal screw ontology 4, will connect
Line screw ontology 4 is tightened, and terminal screw ontology 4 is moved into connection copper piece 5 at this time, by circuit connection compacting in connection copper piece 5
Inner wall completes circuit connection and connects the connection of copper piece 5.
By adopting the above-described technical solution, a kind of socket with terminal screw anti-back structure, passes through the overhead of spring 7
And the limitation of 61 diameter of hole is tightened, it avoids terminal screw ontology 4 from being fallen out outside limitation shell 3 during transportation, is circuit
The installation of wiring provides convenience, and the utility model structure is simple, easy for installation, and effective solution terminal screw ontology 4 exists
The problem of being easy to fall off and lose in transportational process.
Obviously, above-described embodiment is just for the sake of clearly illustrating done citing, and does not limit the embodiments.
To those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
