Abstract
The utility model relates to an electric connector. The electric connector comprises an insulation body, an inner terminal and an outer conductor, wherein the inner terminal and the outer conductor are fixed inside the insulation body. The inner terminal is provided with a plate-shaped matrix, a contact portion and a welding portion, wherein the matrix extends upwards to form the contact portion, and the matrix extends horizontally to form the welding portion. The outer conductor comprises a muff coupling portion and welding feet, wherein the welding feet are formed by outward extension from the bottom of the muff coupling portion, and the muff coupling portion is sleeved and surrounds the outside of the contact portion. The welding portion is provided with a convex hull. When welding is conducted, if tin solders are excessive, the tin solders surround the convex closure, and therefore the situations that the excessively spread tin solders communicates the welding portion and foot portions or the welding feet, and the electric connector is invalid and unusable are avoided. Meanwhile, the back of the convex gull is provided with a groove, and therefore when injection molding is finished, plastic cement can be contained in the groove partially, and structural stability of the electric connector is enhanced.

[utility model content]
The purpose of the utility model is to provide a kind of electric connector, and it can be avoided, and scolding tin is excessive, diffusion and cause this electric connector to lose efficacy.
For realizing above-mentioned purpose, the utility model discloses a kind of electric connector, comprises insulating body and is immobilizated in inner terminal and the outer conductor in the said insulating body.Said inner terminal is provided with a panel-shaped base body, extends upward the contact site of formation and extend in parallel the weld part of formation from said matrix from said matrix.The welding foot that said outer conductor comprises a socket part and stretches out and form from the bottom of said socket part; Said socket part is sheathed and be surrounded on outside the said contact site.Said weld part is provided with a convex closure.
Further, said convex closure is positioned at the weld part middle part, and said convex closure protrudes out direction and said contact site protrudes out in the opposite direction.
Further, said inner terminal and said outer conductor and plastic cement injection mo(u)lding, correspondence is provided with groove to said weld part in the convex closure back side, and said plastic cement partly is contained in the said groove.
Further, said matrix is provided with the depressed part of two symmetries, and said two depressed part lines place direction is vertical with said weld part place direction.
Further, said welding foot comprises two foots and a leg, and the bearing of trend of said leg defines a radial direction, and said two foots are about said radial direction symmetry and laterally arrange, and promptly said two foots place straight line is vertical with said radial direction.
Further, said weld part is along said radial direction extension and opposite with the bearing of trend of said leg.
Further, said foot is provided with two welding blocks and between between said two welding blocks, is separated with a conduit.
Further, said foot is provided with convex closure.
Further, said leg is provided with convex closure.
Compared with prior art; The utility model electric connector has following beneficial effect at least: when welding; If it is excessive that scolding tin takes place; Scolding tin will be centered around convex closure around, and avoid undue diffusion and cause scolding tin that weld part is communicated with foot or leg, cause this electric connector inefficacy and can't use.Simultaneously, because the convex closure back side is a groove, during injection mo(u)lding, plastic cement can partly be contained in the groove, and the structural stability of electric connector will strengthen.

[embodiment]
Below, with combining accompanying drawing to introduce the embodiment of the utility model electric connector 100 in detail.
Consult Fig. 1 to Fig. 5, the utility model electric connector 100 comprises insulating body 1 and is immobilizated in the inner terminal 2 and outer conductor 3 in the insulating body 1.
Said inner terminal 2 is formed through punching press by metallic plate, and it is provided with a tabular matrix 21, extends upward the cylindric contact site 22 of formation from said matrix 21 middle parts and holds the weld part 23 that row extends to form level with both hands from said matrix 21 1.Said matrix 21 bottom surfaces are provided with the depressed part 211 of two symmetries, and the direction at said two depressed parts, 211 lines place is vertical with the direction at said weld part 23 places.Said weld part 23 downward punching presses form a convex closure 231, and promptly said convex closure 231 protrudes out direction and said contact site 22 protrudes out in the opposite direction.The back side of said convex closure 231 corresponds to a groove 232.When injection mo(u)lding, plastic cement partly is contained in said two depressed parts 211 and the said groove 232, and the structural stability of the utility model electric connector 100 will strengthen.
Said outer conductor 3 is formed through punching press by metal material, and it comprises a socket part 31, two foots 32 and the leg 33 that stretch out and form from the bottom of said socket part 31.Said foot 32 and said leg 33 are referred to as welding foot (not label).Said socket part 31 is provided with the caulking groove 311 that supplies butt connector (not shown) engagement.The bearing of trend of said leg 33 defines a radial direction.Said two foots 32 are about said radial direction symmetry and laterally arrange, and promptly said two foots 32 place straight lines are vertical with said radial direction.Said foot 32 is provided with two welding blocks 321 and between between said two welding blocks 321, is separated with a conduit 322.In welding process, unnecessary scolder can accumulate in 322 li of said conduits and have influence on effectively being welded to connect of said foot 32 and circuit board (not shown) to avoid scolder to overflow said foot 32.
During assembling, at first outer conductor 3 is sheathed on outside the inner terminal 2; The socket part 31 of outer conductor 3 is surrounded on outside the contact site 22 of inner terminal 2, and weld part 23 radially extends and be opposite with the bearing of trend of leg 33.Insulating body 1 is injected and molded on inner terminal 2 and the outer conductor 3 then; Inner terminal 2 is stablized fixing with outer conductor 3 and insulating body 1.
Because weld part 23 is provided with the convex closure 231 that protrudes out downwards; When welding, if it is excessive that scolding tin takes place, scolding tin will be centered around convex closure 231 around; And avoid undue diffusion and cause scolding tin that weld part 23 is communicated with foot 32 or leg 33, render electrical connector 100 inefficacies and can't using.Simultaneously, because convex closure 231 back sides are a groove 232, during injection mo(u)lding, plastic cement can partly be contained in the groove 232, and the structural stability of electric connector 100 will strengthen.
In other embodiments, foot 32 or leg 33 also can be provided with convex closure so that unnecessary scolding tin be centered around convex closure around, and avoid undue diffusion.
The above is merely a kind of execution mode of the utility model; It or not whole execution modes; The variation of any equivalence that those of ordinary skills take the utility model technical scheme through reading the utility model specification, the claim that is the utility model contains.
