Description
Technical field:
The present invention relates to power connector equipment technical fields, more specifically to a kind of power supply with holddown spring
Connector connecting structure.
Background technique:
Connector on power connector, such as the connector of various mobile phones, aviation plug, computer mainly connects
The effect of various electrical equipments is connect, and existing power connector only has the function of that connection is conductive and transmits signal, not
There is water proof and dust proof, so that when in use, when splashing aqueous or accumulating excessive dust, being easy to influence conductive stabilization
Property, or even make its breakage.
And as in aviation plug, after pin end is inserted into female connector, need to rotate the turning set outside pin end, so that
External screw thread connection on the lateral wall of turning set and female connector, and when multiple installing and dismounting can make the outer of turning set and female connector
Precision decline between screw thread, so that the two has loosening, it is subsequent to be easy to come out turning set from female connector transfer, so that
When transporting or shaking big place installation, the two is easy abjection, influences connection effect.
Summary of the invention:
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of power connector connection with holddown spring
Structure, it makes protrusion be spirally connected column and when outer sleeve body is spirally connected by holddown spring, and holddown spring is spirally connected one, column outward to protrusion
Thrust, also has the outside thrust an of opposite direction to outer sleeve body, so that protrusion is spirally connected, column and outer sleeve body are compacted, it is not easy to
It loosens, thus guarantee that the two is multiple regardless of using, regardless of being not readily disengaged from any environment, guarantee connection effect.
The solution to the technical problem of the present invention is as follows:
A kind of power connector connection structure with holddown spring, including power connector pin end and power connector
Female connector, the top of the power connector pin end form connecting plate, and the power supply on the top of power connector pin end connects
The middle part of connecting plate is stretched out in wiring, and electric power connection line sleeve runs through through-hole, electricity at the center that the middle part of the top plate of outer sleeve body has
For source connector pin end sleeve in outer sleeve body, the middle part bottom surface of the top plate of outer sleeve body has annular groove, self-lubricating annular slab
For sleeve in annular groove, the electric power connection line upper sleeve between outer sleeve body and connecting plate has holddown spring, holddown spring
Upper end put forth effort on the bottom surface of self-lubricating annular slab, the top surface of connecting plate is put forth effort in the bottom end of holddown spring；
There is protrusion to be spirally connected column, protrusion, which is spirally connected on the lateral wall of column, to be had in the middle part of the top surface of the power connector female connector
External screw thread and the inner sidewall of outer sleeve body on the internal screw thread that has it is corresponding；
In the top surface for the main interconnecting piece that the top surface of the contact pin of the power connector pin end and the raised column that is spirally connected forms
The jack that portion has is corresponding.
The top surface edge of the main interconnecting piece has the ring part upwardly extended, the bottom of power connector pin end and ring
Shape portion matches.
The top surface edge of the connecting plate has upper annular groove, and wear-resisting lubrication ring body sleeve is in upper annular groove, pressure
Put forth effort on the top surface of wear-resisting lubrication ring body in the bottom end of tight spring.
The edge of the top surface of the main interconnecting piece forms annular seal grooves, and it is recessed that ring type seal is nested in ring packing
In slot.
The top surface of the ring type seal is higher than the top surface of main interconnecting piece.
Protrusion effect of the invention is: compared with prior art, it makes protrusion be spirally connected column and housing by holddown spring
When body is spirally connected, holddown spring is spirally connected one outward thrust of column to protrusion, and also there is the outside of an opposite direction to push away to outer sleeve body
Power, so that protrusion is spirally connected, column and outer sleeve body are compacted, it is not easy to be loosened, to guarantee the two regardless of using repeatedly, regardless of in office
What environment not readily disengages from, and guarantees connection effect.
Detailed description of the invention:
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment:
Embodiment is shown in as shown in Figure 1, a kind of power connector connection structure with holddown spring, including power supply connect
Device pin end 10 and power connector female connector 20, the top of the power connector pin end 10 form connecting plate 11, electricity
The electric power connection line 12 on the top of source connector pin end 10 stretches out the middle part of connecting plate 11, and 12 sleeve of electric power connection line is in housing
Through-hole 14 is run through at the center that the middle part of the top plate of body 13 has, and 10 sleeve of power connector pin end is in outer sleeve body 13, housing
The middle part bottom surface of the top plate of body 13 has annular groove 131, and 15 sleeve of self-lubricating annular slab is in annular groove 131, in outer
12 upper sleeve of electric power connection line between body 13 and connecting plate 11 has holddown spring 16, and the upper end of holddown spring 16 is put forth effort on certainly
The bottom surface of annular slab 15 is lubricated, the top surface of self-lubricating annular slab 15 is pressed against on the top surface of annular groove 131, holddown spring 16
Put forth effort on the top surface of connecting plate 11 in bottom end；
There is protrusion to be spirally connected column 21, protrusion is spirally connected the lateral wall of column 21 in the middle part of the top surface of the power connector female connector 20
On the internal screw thread that has on the external screw thread and the inner sidewall of outer sleeve body 13 that have it is corresponding；
The main interconnecting piece 22 that the top surface of the contact pin of the power connector pin end 10 and the raised column 21 that is spirally connected forms
The jack having in the middle part of top surface is corresponding.
Further, the top surface edge of the main interconnecting piece 22 has the ring part 23 upwardly extended, power connector
The bottom of pin end 10 is matched with ring part 23.
Further, the top surface edge of the connecting plate 11 has upper annular groove 111, and wear-resisting lubrication ring body 112 is inserted
It covers in upper annular groove 111, the top surface of wear-resisting lubrication ring body 112, wear-resisting lubrication ring body are put forth effort in the bottom end of holddown spring 16
112 bottom surface is pressed against on the bottom surface of annular groove 111.
Further, the edge of the top surface of the main interconnecting piece 22 forms annular seal grooves 24, ring type seal
25 are nested in annular seal grooves 24.
Further, the top surface of the ring type seal 25 is higher than the top surface of main interconnecting piece 22.
Working principle: when in use, the contact pin of power connector pin end 10 is inserted into the middle part of the top surface of main interconnecting piece 22
In the jack having, the bottom sleeve of power connector pin end 10 is in ring part 23, the bottom of power connector pin end 10
Face pressure leans against on the top surface of ring type seal 25, then, rotating jacket body 13, so that outer sleeve body 13 is screwed onto protrusion and is spirally connected column 21
In, holddown spring 16 compresses, at this point, the bottom surface of self-lubricating annular slab 15 is put forth effort in one end of holddown spring 16, the other end is puted forth effort
In the top surface of wear-resisting lubrication ring body 112, thus between the internal screw thread of outer sleeve body 13 and protrusion are spirally connected between the external screw thread of column 21
Gap compresses, so that the two is not easy to loosen, it is not easy to unscrew, guarantee the connection effect of the two.
