Referring to fig. 5-7, the contact 12 has a plurality of second notches 121 and a plurality of third notches 122 at two ends thereof. The number of the first fixture blocks 1111 is the same as that of the second notches 121, and the plurality of first fixture blocks 1111 are respectively clamped into the plurality of second notches 121 for fixation. The plurality of first notches 112 respectively correspond to the plurality of third notches 122, that is, the first notches 112 and the second notches 121 form a notch group. The waist of the contact 12 includes a plurality of bars 123 that are inclined to the tangent plane of the contact 12. Specifically, the contact element 12 in this embodiment is an annular structure, a plurality of bars 123 are punched on the side wall of the contact element, and then one end of the contact element 12 is fixed and the other end is rotated, in this process, the bars 123 are kept in a straight bar shape, and finally, a waisted annular structure is formed.
Referring to fig. 8, a plurality of second latches 131 are disposed on an end surface of the latch cover 13, wherein the number of the second latches 131, the number of the first notches 112 and the number of the third notches 122 are the same. Each second latch 131 is snapped into the corresponding first notch 112 and third notch 122 for fixation, in other words, the second latch 131 is snapped into the notch group for fixation. The hole sleeve 11 and the contact element 12 can be fixed by using a clamping block, and the two can be tightly fixed together, so that the stability of connection and fixation is improved.
The side wall of the card cover 13 is provided with a plurality of first hooks 132 arranged around at equal intervals, and the plurality of first hooks 132 are clamped into the annular card slot 113 and fixed. The locking and fixing of the clamping cover 13 and the hole sleeve 11 are realized through a simple clamping hook structure. If the elasticity of the contact 12 is weakened to be incapable of being normally connected and conducted, the snap structure of the card cover 13 and the hole sleeve 11 is disassembled to realize the removal of the contact 12. And then the structure of the card cover 13 and the hole sleeve 11 is reserved by replacing the contact piece 12, so that the cost expenditure of unnecessary components is saved, and the maintenance cost is saved.
Referring to fig. 9-11, the angle between the grid 123 and the tangent plane of the contact 12 is in the range of 50 ° to 90 °, and the over-twisting of the contact 12 can be achieved within this angle range. Under the premise that the waist of the contact 12 in the overtwisted state is in contact with the inner diameter of the contact pin 20, and the outer diameter of the standard contact pin 20 is the same, the included angle degree between the grid 123 of the contact 12 and the tangent plane is increased, so that the outer diameter formed by the end part of the grid 123 is increased, and the outer diameter of the contact 12 can be increased. The increased outer diameter of the contacts 12 may correspond to an increased density of the bars 123, i.e., an increased number of bars 123. The increased number of bars 123 corresponds to an increased effective conductive cross-sectional area a when the pin 20 is in contact conduction with the contact 12.

The second latch 131 is locked in the notch set by rotating the latch cover 13, and the first hook 132 is locked in the annular slot 113. The first hook 132 and the guide ring 133 clamp the socket 11 and the contact 12 to be fixed, so that both ends of the socket 11 and the contact 12 are fully contacted.
Combining the above formula, the two ends of the sleeve 11 and the contact 12 are fully contacted, i.e. the effective conductive cross-section area a of the conductor is increased, and therefore, the contact resistance R can be reduced. Helping to improve the electrical conduction efficiency of the jack 10.

The other end face of the annular main body is provided with a plurality of inserting pieces, and the inserting pieces are inserted into the inserting slits 135. Specifically, when the maintenance is needed to be dismantled, the inserting sheet is inserted into the inserting slot 135 and then continuously pushed until the inserting sheet is inserted between the first hook 132 and the hole sleeve 11, at the moment, the hook part of the first hook 132 is pulled out of the annular slot 113, and then the clamping cover 13 is pulled out, so that the dismantling process is more convenient.
Example two:
referring to fig. 12-14, in the first embodiment, an annular spring 115 is disposed inside the hole sleeve 11, and the annular spring 115 is sleeved on the waist portion of the contact 12.
When the contact pin 20 is inserted, the contact pin 20 is in top contact with the inner surface of the middle part of the grid bar 123, and then the grid bar 123 deforms and moves towards the inner wall direction of the hole sleeve 11, and the annular spring 115 is extruded and deformed; at this time, the current can pass through the contact area in the middle of the grid 123, the annular spring 115 and the hole sleeve 11 at one time, the conductive distance is shortened, the conductive sectional area is increased, the contact resistance is further reduced, and the conductivity of the grid is obviously improved. Because the annular spring 115 and the grid 123 are adopted to jointly push against the contact pin 20, the restoring capability of the contact 12 is relatively improved, and the durability of the contact is further improved.
Preferably, the inner wall of the hole sleeve 11 is further provided with an annular groove 116, and the annular spring 115 is clamped in the annular groove 116 for fixation.

Preferably, in this embodiment, an auxiliary annular spring may be additionally disposed at two sides of the annular spring 115 to assist the grid 123 of the contact 12 to be pressed against, so as to further improve the conductivity.
Referring to fig. 15-17, the present disclosure further provides a fixing structure for a jack 10, which includes the jack 10, a socket 30 and a locking plate 40.
The side wall of the hole sleeve 11 of the jack 10 is provided with a side clamping groove 114, and the side clamping groove 114 is arranged at one end of the hole sleeve 11 far away from the clamping cover 13.

At present, the same kind of products need two sets of large and small jacks 10 to be nested and fixed in the socket 30 to form a plug connector, and then the plug connector is conducted with the pins 20 with standard outer diameters. The multilevel nested structure is complex, and the multilevel nested structure belongs to the extended conducting distance L by combining the contact resistance formula, so the conducting performance of the structure is limited to a certain extent. Also, the complex structure is not easily repaired after the contact 12 fails.
On the premise of ensuring that the contact inner diameter of the contact 12 is the same as the outer diameter of the standard pin 20, the angle between the grid 123 of the contact 12 and the tangent plane thereof is increased (i.e. the overtwist structure described in the first embodiment), and the outer diameter formed by the end of the grid 123 is increased, so that the outer diameter of the hole sleeve 11 can be increased. Finally, one group of jack 10 structure can meet the contact conduction of the nested structure of two groups of jacks 10 of the same type. The structure of the set of jacks 10 will greatly reduce the conductive distance L, so it will have a significant effect on the conductivity of the socket 30.
