Description
Technical Field
The utility model relates to a power plug technique specifically is a female structure of inserting connecting terminal of power.
Background
The existing power supply plug connector generally comprises a female plug and a male plug, two power supply plug holes and a plurality of signal plug holes are arranged on a body of the female plug, connecting terminals are embedded in the power supply plug holes and the signal plug holes, the connecting terminals are made of pure copper materials and are provided with a plug interface and a connecting end, the plug interface is divided into a petal-shaped structure, the problems of deformation of the plug interface, port expansion and the like of the plug interface generally cannot be caused when the conventional connecting terminals are normally plugged along the axial direction of the plug holes, but in the using process, many consumers cannot pay attention to obliquely inserting the male plug into the plug interface of the female plug, as the body of the female plug is generally made of insulating engineering plastic materials, and meanwhile, the pure copper materials are soft, the deformation of the plug interface of the plug hole and the connecting terminal is easily caused by the regular oblique plugging, so that the connection between the female plug and the male plug is not tight, the connector is loosened, arcing and other ignition phenomena are easy to occur when gaps exist between the plug connectors, and great potential safety hazards exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a female structure of inserting connecting terminal of power, the outside cover of connecting terminal is equipped with the nonrust steel bushing, leaves the clearance between the grafting port outer wall of nonrust steel bushing inner wall and connecting terminal, interference fit between the nonrust steel bushing other end and the connecting terminal outer wall, and the nonrust steel bushing is worn out to the link of connecting terminal, the utility model discloses cup joint the nonrust steel bushing in the connecting terminal outside, the nonrust steel bushing has the characteristics of the high difficult change of intensity, can avoid public affairs to insert the problem that causes the grafting port of connecting terminal to warp when the interface of female inserting to promote product reliability and durability.
The following technical scheme is adopted for achieving the purpose:
the utility model provides a female plug connection terminal's of power structure, includes columnar connecting terminal, and the spliced eye has been seted up along the connecting terminal axial to connecting terminal one end, has seted up a plurality of axial grooves in spliced eye port department, and the length in axial groove is less than the degree of depth of spliced eye, and the axial groove forms lamella portion in connecting terminal's one end, and connecting terminal's the other end has a connecting end, its characterized in that: the stainless steel sleeve is sleeved outside the connecting terminal, a gap is reserved between the inner wall of the stainless steel sleeve and the outer wall of the petal-shaped portion, and the stainless steel sleeve is in interference fit with the outer wall of the middle portion of the connecting terminal.
The outer diameter of the petal-shaped part gradually increases from the port to the connecting end.
The connecting end penetrates out of the stainless steel sleeve port.
And a limiting convex ring is arranged on the outer wall of the stainless steel sleeve.
The surface of the limiting convex ring is provided with an anti-rotation rack.
The width of the axial groove gradually increases from the port to the inner side.
The utility model discloses having cup jointed nonrust steel bushing in the connecting terminal outside, nonrust steel bushing has the characteristics of the high difficult change of better intensity for the connecting terminal of pure copper material, and bilayer structure connecting terminal has both kept original whole characteristics, has solved current interface simultaneously and has gone out the interface expansion easily when the slant inserts, the problem that the interface of connecting terminal warp to the reliability and the durability of product have been promoted.

Detailed Description
As shown in fig. 1-4, a structure of a power supply female plug connection terminal comprises a columnar connection terminal 1, wherein an insertion hole 11 is formed in one end of the connection terminal 1 along the axial direction of the connection terminal, a plurality of axial grooves 12 are formed in the port of the insertion hole, the length of each axial groove 12 is smaller than the depth of the insertion hole, a petal-shaped portion 13 is formed in one end of the connection terminal by the axial grooves 12, a connection end 14 is arranged at the other end of the connection terminal 1, a stainless steel sleeve 2 is sleeved outside the connection terminal 1, a gap 3 is reserved between the inner wall of the stainless steel sleeve 2 and the outer wall of the petal-shaped portion, the width of each axial groove 12 is gradually increased from the port to the inner side, the outer diameter of the petal-shaped portion 13 is gradually increased from the port to the connection end, and the stainless steel sleeve 2 is in interference fit with the outer wall in the middle of the connection terminal 1.
The connecting end 14 penetrates out of the port of the stainless steel sleeve; a limiting convex ring 21 is arranged on the outer wall of the stainless steel sleeve 2; the surface of the limit convex ring 21 is provided with an anti-rotation rack.
The utility model discloses stainless steel cover has been cup jointed in the connecting terminal outside, and the body injection moulding that mother inserted wraps up the stainless steel cover in inside, and connecting terminal 1 and the stainless steel cover of pure copper material link firmly to the width of axial groove 12 increases gradually from the port inboard, the external diameter of lamella portion 13 increases gradually from the port toward the link, and this kind of structure lamella portion is slightly to middle shrink at the spliced eye port, and the change form is great when the plug of public inserting is inserted, expands easily, and the lamella portion variable quantity is more little when going towards the inside depth more, is favorable to cramping the plug of public lock.
