Description
Technical field
The present invention relates to photovoltaic technology field, and in particular to connector.
Background technique
The application for a patent for invention of 104659519 A of application publication number CN discloses a kind of photovoltaic junction box connector,
In, the wire bushing being sheathed on cable is equipped in tightening nut and is held down assembly, and wire bushing holds down assembly set on the metal electrode
Between tightening nut and integrated support is formed, the pulling capacity between adapter body and cable still may be used at least 400N.m
The metal electrode is avoided to pull out from above-mentioned adapter body.
The tightening nut of foregoing invention patent application during being tightened in adapter body, drives wire bushing compression group
Part generates certain torsion to cable, may cause cable quick aging.
Summary of the invention
Technical problem solved by the invention: tightening nut in the prior art generates tension because torsion is unable to control
Or excessively loose situation, cause connector to fail, alternatively, extending out because tightening nut expansion, causes to tighten nut rupture.
In order to solve the above technical problems, the invention provides the following technical scheme: a kind of connector equipped with self-locking structure, packet
Include the adapter body and tightener being installed together by sleeve mode；The lateral wall of the adapter body and the inside of tightener
Matching design has snap-in structure on wall, and the snap-in structure includes guide frame and hook structure, under the guiding of guide frame,
After adapter body and tightener make opposed helical movement, then linked together by hook structure.
According to the above technical scheme, present invention tightener substitutes the tightening nut in traditional technology, and tightener passes through sleeve
Mode be set in adapter body；In tightener sleeve during in adapter body, under the guiding of guide frame, receive
Screw (combination of linear motion and rotary motion) occurs for tight part opposing tabs main body first, and later, tightener passes through card
Hook structure links together with adapter body, at this point, tightener tightens the cable being plugged in adapter body.
The design of the snap-in structure can be the following two kinds:
The first snap-in structure, including be arranged on adapter body lateral wall clamping groove, be arranged in tightener inner sidewall
On clamping bump；The side of the clamping groove is equipped with arcuate guide edge, and the opposite side of clamping groove is equipped with barb, the clamping
The side of convex block is equipped with the mating guide edge with arcuate guide edge mate, and the opposite side of clamping bump is equipped with to be cooperated with barb
Barb slot.The obliquely downward of the clamping groove is equipped with the depth link slot being connected to clamping groove, and the side of depth link slot is equipped with
Depth barb is equipped with the opposite side at the depth arcuate guide edge of arcuate guide edge junction, depth clamping groove.
The first above-mentioned snap-in structure, clamping bump drive tightener along connector master under the guiding at arcuate guide edge
Screw occurs for body, and when clamping bump to clamping trench bottom, barb and barb slot cooperate, and realizes tightener and adapter body
Preliminary connection；Later, under the guiding at depth arcuate guide edge, clamping bump continues that tightener is driven to occur along adapter body
Screw, when clamping bump to depth is clamped trench bottom, depth barb and barb slot cooperate, and realize tightener and adapter body
Depth connection, at this point, the end face of tightener offsets with the convex shoulder on adapter body side wall.
Second of snap-in structure, including be arranged on tightener inner sidewall clamping groove, be arranged in adapter body lateral wall
On clamping bump；The side of the clamping groove is equipped with arcuate guide edge, and the opposite side of clamping groove is equipped with barb, the clamping
The side of convex block is equipped with the mating guide edge with arcuate guide edge mate, and the opposite side of clamping bump is equipped with to be cooperated with barb
Barb slot.The obliquely downward of the clamping groove is equipped with the depth link slot being connected to clamping groove, and the side of depth link slot is equipped with
Depth barb is equipped with the opposite side at the depth arcuate guide edge of arcuate guide edge junction, depth clamping groove.
Above-mentioned second of snap-in structure, clamping bump drive adapter body along tightening under the guiding at arcuate guide edge
Screw occurs for part, and when clamping bump to clamping trench bottom, barb and barb slot cooperate, and realizes tightener and adapter body
Preliminary connection；Later, under the guiding at depth arcuate guide edge, clamping bump continues that adapter body is driven to occur along tightener
Screw, when clamping bump to depth is clamped trench bottom, depth barb and barb slot cooperate, and realize tightener and adapter body
Depth connection, at this point, the end face of tightener offsets with the convex shoulder on adapter body side wall.
The end of the adapter body is connected with wire bushing by chocking construction and holds down assembly, the chocking construction limitation shield
Line set hold down assembly with adapter body occur circumference to relative rotation, the medial end of tightener is arcuate structure, is plugged in
Wire bushing in the tightener end that holds down assembly by arcuate structure is extruded from closing.About chocking construction, adapter body
End is serrated, and the end that wire bushing holds down assembly also is serrated, the adapter body end being coupled and wire bushing pressure
Tight component end constitutes chocking construction.The other end that wire bushing holds down assembly is equipped with several axially projecting elastic components, several bullets
The circumference that property part holds down assembly along wire bushing is to being uniformly distributed, in this way, under the extruding of arcuate structure, several elastic components are to center
It draws close, forms so-called closing, cable is pressed in adapter body in several elastic components of closing.
The quantity of the snap-in structure is two or more, and more than two snap-in structures divide along the circumference of connector to uniform
Cloth.
The present invention substitutes tightening nut in the prior art by the tightener that is set in adapter body, by cable pressure
While tightly in adapter body, tightening nut is efficiently solved because torsion is unable to control and generates too tight or too loose situation, is led
Cause connector failure the technical issues of and because tighten nut expansion due to extend out, cause tighten nut rupture the technical issues of.
