Referring to Figure 1 to Fig. 3, receptacle body 2 has a positioning body, and the upper surface of the positioning body is equipped with one and upwardly extends
Hollow convex column 21, there are two above flutings 211 along axial spaced set for the top half of hollow convex column 21；Positioning body
Upper surface the side of hollow convex column 21 have a locating slot 22 opposite with 21 extending direction of hollow convex column.
1 bottom of contact flat spring of the present embodiment is equipped with horizontal connection portion 101, and 101 center of horizontal connection portion is equipped with circular hole 109
And it can be placed on the outer peripheral surface of the hollow convex column 21 at 2 top of receptacle body, the first side in horizontal connection portion 101 is equipped with successively upwards
Connected vertical joints 103, the first bending section 104, the second bending section 105 and third bending section 106.Horizontal connection portion
101 second side has extended downwardly bending part 102 used for positioning；Wherein, first side and second side are horizontal connection
Opposite two side in portion 101.
The contact flat spring group as composed by two symmetrically arranged two panels contact flat springs 1 can pass through respective third bending section
106 elastic fits are connected, in use, the contact flat spring group can be symmetrically arranged on inside heavy-duty connector, when contact flat spring 1 passes through
After the circular hole 109 at center is placed on 21 outer peripheral surface of hollow convex column at 2 top of receptacle body, the side of the first bending section 104 of contact flat spring 1
Face is butted on the outer peripheral surface of 2 hollow convex column 21 of receptacle body, and two third bending sections 106 are bonded to each other contact.
The vertical joints 103 of the present embodiment, the first bending section 104, the second bending section 105 and third bending section 106
Form the interior kinking structure of contact flat spring 1, it is preferable that first bending section 104 of the present embodiment, 106 inner wall of third bending section folder
Angle is obtuse angle, and the inner wall angle of the second bending section 105 is acute angle.
In addition, the positioning that bending part 102 is inserted into receptacle body 2 is inserted to realize that contact flat spring 1 is reliably connected with receptacle body 2
In slot 22, outwardly protrudes and be used for elastic card tightening position it is further preferable that the present embodiment is equipped on bending part 102 and electrically connect
The elastic construction 110 connect is realized more reliable between contact flat spring 1 and receptacle body 2 with being caught in the locating slot 22 of receptacle body 2
Connection.
The contact flat spring 1 of the present embodiment is equipped with two notches 108 on the top of vertical joints, and two notches 108 it
Between part be connected with the first bending section, by be arranged notch 108 can prevent contact flat spring 1 in flexible deformation be easy hair
Raw stress is excessively concentrated and causes structural failure.
Referring to Figure 1 to Fig. 4, the working principle of the contact flat spring of the present embodiment are as follows:
Contact pin 33 is installed with inside the contact pin insulator 31 of contact pin insulation components 3 from top to bottom, and in contact pin insulator
Bottom surface is to having a mandril 32 in the open cavity body of 31 bottoms, and 41 internal symmetry of jack insulator of jack insulator component 4
Equipped at least one set of receptacle body 2,4 side of jack insulator is connected with 43 screw thread of fastening screw, and 43 end of fastening screw is stretched
Enter to receptacle body 2, and 21 outer peripheral surface of hollow convex column at 2 top of receptacle body is connected with the socket of contact flat spring 1, then passes through jack
The fixing piece 42 at 31 top of insulator is fixed inside jack insulator 41 by contact flat spring 1 and receptacle body 2, insulate in contact pin
Under body component 3 and the non-inserting state of jack insulator component 4, symmetrically arranged two panels contact flat spring 1 is curved by respective third
Pars convoluta 106, which is realized to be shorted between the two, to be connected.
When contact pin insulation components 3 and jack insulator component 4 are mutually inserted, the contact pin 33 of contact pin insulation components 3
With mandril 32 also cross fixing piece 42, and contact pin 33 is inserted directly into the jack 44 of jack insulator component 4, and mandril 32
It is inserted into position opposite two panels contact flat spring 1 across the avoid holes 421 of 42 axial centre of fixing piece, passes through isolation material
Mandril 32 realize script elastic fit two panels contact flat spring 1 between be separated from each other.When contact pin insulation components 3 and jack are exhausted
When edge body component 4 is separated from each other, contact pin 33 is detached from the grafting relationship of jack 44, and mandril 32 is then detached from two panels contact flat spring 1
Elastic fit position realizes that two panels contact flat spring 1 is bonded again and is connected.
It should be noted that may include inside the contact pin insulation components 3 of the heavy-duty connector of the present embodiment several groups not
With contact pin 33, the pressure line type jack or screw in compression formula jack that corresponding jack insulator component 4 is equipped with respectively with contact pin 33
Grafting is connected.
By the way that heavy-duty connector can be realized in contact pin insulation components 3 and the grafting close to each other of jack insulator component 4
Internal structure connection, and in contact pin insulation components 3 and jack insulator 4 grafting of component, contact pin 33 and 44 phase interfix of jack
Connect connected, mandril 32 enters to by avoid holes 421 and will be bonded to each other connected two panels contact flat spring 1 inside fixing piece 42 originally
It is mutually isolated.And after contact pin insulation components 3 and jack insulator component 4 are separated from each other, mandril 31 is detached from two panels and contacts bullet
Piece 1 is connected so that two panels contact flat spring 1 is bonded again.Therefore the contact flat spring 1 of the present embodiment can be applied to heavy-duty connector
And on the current transformer of electric power network, since the secondary side of current transformer is not allow to open a way, in the secondary of equipment
Side has in the instrument of detection electric current, and plug and socket is mutual plugging state, and the contact of plug and socket at this moment is mutual
It connects, that is to say that secondary side is in channel status.When detection device breaks down, and detection device and primary side need to disconnect,
It then needs to separate connector, but during the separation process, when contact pin 33 and jack 44 are not yet completely disengaged and contacted, lead to
Cross adjacent two panels contact flat spring 1 realize automatically contact with each other be bonded it is connected, to guarantee that secondary side is in channel status forever.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
