It is interior, in order to which joint body 1 is passed through out of outlet hole, in a free state when Elastic buckle 12 is not pressurized, elasticity
It is protruding to buckle 12, and protrudes from 14 top of telescopic chute at the top of 11 side of annular convex platform, and Elastic buckle 12 exists
When free state, protrusion and the outer diameter of 14 part of telescopic chute are greater than outlet bore dia, thus can pass through annular convex platform 11 and elasticity
12 protrusions are buckled to limit end cap.As shown in figure 3, Elastic buckle 12 includes two buckles arranged side by side, telescopic chute 14 is
Square structure, the shape and 14 shape of telescopic chute of certain Elastic buckle 12 are not limited only to the shape of above-mentioned record, limit knot
As long as structure can play perforation when joint body 1 can be made to pass through, through position after joint body 1 can be limited.
Elastic buckle 12 can be used structure in the prior art and realize, spring is arranged at buckle bottom, in order to buckle the retraction that is pressurized, free bullet
Requirement out.
In order to enable position limiting structure to limit end cap, 13 width of limit card slot is not less than installation device thickness.Specifically,
13 width of limit card slot between annular convex platform 11 and Elastic buckle 12 is not less than the thickness of end cap.
As shown in figure 5, in order to improve limit connection intensity and stress equalization, the quantity of position limiting structure be at least one
A, all position limiting structures are circumferentially uniformly or non-uniformly arranged along joint body 1.
As an alternative embodiment, 1 one end of joint body is provided with the wire portion 15 penetrated convenient for lead.
As another optional embodiment, as shown in Figure 1 and Figure 4, it is provided in 11 inner cavity of annular convex platform convenient for drawing
The wire portion 15 that line penetrates.
Further, in the present invention, wire portion 15 is toroidal structure, passes through the wire portion 15 of toroidal, tool
There is the characteristics of guidance lead penetrates, so that it is more convenient to penetrate lead, quickly, improves working efficiency.
Wire portion has sharp corner in order to prevent, and causes to damage to lead, the present invention in, 15 both ends of wire portion respectively with
It is arc transition structure between 1 inner cavity of 11 top surface of annular convex platform and joint body.
As shown in Figure 3 and Figure 4,1 inner cavity of joint body is hierarchic structure, including the first chamber 16 and the second chamber 17, the first chamber
For 16 diameters less than 17 specification of the second chamber, joint body 1 is arranged in close to one end of the first chamber 16, annular convex platform 11 in annular convex platform 11
Inner cavity specification is identical as 16 specification of the first chamber.
As an alternative embodiment, outlet joint further includes can with joint body 1 in order to protect to lead
The lead protecting tube of dismantling connection.
Pilot protection pipe is corrugated flexible metal tube, is provided in compatible with corrugated flexible metal tube specification in the second chamber 17
Thread segment 171.Corrugated flexible metal tube is threadedly coupled by internal thread segment 171 with joint body 1.
It is provided with cell wall 172 as shown in figure 4, extending axially downward at step between the first chamber 16 and the second chamber 17,
Annular shield slot 18 is formed between cell wall 172 and the second chamber 17, when lead protecting tube is connect with joint body 1, end insertion
Into annular shield slot 18；Corrugated flexible metal tube head is pierced into annular shield slot 18, and corrugated flexible metal tube head burr is prevented
It is directly contacted with power supply line, damages power supply line.
In order to avoid cell wall 172 causes to damage to lead, cell wall 172 end of the annular shield slot 18 close to 16 position of the first chamber
Portion is arc transition structure.
