Abstract
The utility model discloses an electric connector which includes a housing, an insulating body, and a connecting terminal. The connecting terminal is arranged on the insulating body and is electrically connected with a printed circuit board. The insulating body is fixed in the housing. The housing is fixed on the printed circuit board. The rear of the housing is provided with a plurality of fixed feet. One end of the fixed foot is fixedly connected with the housing, and the other end is provided with grooves. The printed circuit board is provided with fixed holes. The fixed feet stretch into the fixed holes and are fixed on the printed circuit board via soldering tin to form a welding area. The welding area covers the fixed holes and coats the grooves. Because the fusing tin in the welding area is injected into the fixed holes to fill the grooves, the welding area between the housing and the printed circuit board is increased, the connecting strength of the housing is also improved, and the signal instantaneous turnoff phenomenon of the connector can be avoided.
Description
Technical field
The utility model relates to a kind of electric connector, relates in particular to a kind of bonding strength that strengthens between connector and the printed circuit board (PCB), avoids occurring the electric connector of intermittent disconnection of signal phenomenon.
Background technology
Along with progress of science and technology; PC is used widely; Its external equipment is also more and more; Mouse, printer, joystick, audio amplifier, mobile storage disc etc., each external equipment all need link to each other with PC through an interface, and the exchanges data transmission between the different electronic equipments becomes frequent day by day.Electric connector is because of it has plug and play, transmission speed is fast, connects a plurality of advantages such as flexible and in PC and other external equipments, obtained using widely, and USB connector has become exchanges data input/output interface commonly used between the distinct electronic apparatuses.
And Along with computer technology develops to miniaturization, and electric connector also develops to more and more littler direction thereupon.As depicted in figs. 1 and 2, traditional miniature electric connector (MicroUSB) female connectors 400 generally comprises insulation plastic cement 401, splicing ear 402 and metal shell 403.This metal shell 403 generally in both sides and end extend fixing feet 403a, this fixing feet 403a is connected with printed circuit board (PCB) 200 scolding tin, thus fixing whole electric connector.Yet; Through finding in the daily use; The phenomenon of intermittent disconnection of signal appears in miniature electric connector now sometimes; Its reason is that the metal shell 403 of these electric connectors inserts time institute externally applied forces to bear public connector 300 to female connectors 400 with the undercapacity of printed circuit board (PCB) 200 junctions.
As shown in Figure 2, find through test, under male and female connector 300,400 cooperation situations; One vertical F acts on public connector 300 sides; The fixing feet 403a of shell 403 and printed circuit board (PCB) 200 junctions are because the welding region area is little, and the metal shell 403 of female connectors 400 can't bear the F active force with joint efforts with the welding work of printed circuit board (PCB) 200, makes fixing feet 403a be forced upwardly or extrude downwards; Thereby drive the whole casing displacement; Cause the soldering-tin layer fracture of splicing ear 402, the splicing ear 402 of female connectors 400 and the contact of printed circuit board (PCB) 200 are broken off, so that the phenomenon of intermittent disconnection of signal occurs.
The utility model content
The purpose of the utility model is to the deficiency of above-mentioned prior art a kind of bonding strength that can strengthen between connector and the printed circuit board (PCB) to be provided, and avoids connector the electric connector of intermittent disconnection of signal phenomenon to occur.
For realizing above-mentioned purpose, the electric connector that the utility model provided is installed on the said printed circuit board (PCB); Comprise shell, insulating body and splicing ear; Said splicing ear is installed on the said insulating body and with said printed circuit board (PCB) and electrically connects, and said insulating body is fixed in said enclosure, and said shell is fixed on the said printed circuit board (PCB); The rear end of said shell is provided with several fixing feet; One end of said fixing feet is fixedly connected with said shell, and the other end offers groove, and said printed circuit board (PCB) offers fixing hole; Said fixing feet stretches in the said fixing hole and fixes the formation welding region with said printed circuit boards solder, and said welding region covers said fixing hole and coats said groove.
As above; Because the utility model is offered said groove through the fixing feet both sides at said shell; And on said printed circuit board (PCB), offer fixing hole; Said fixing feet is stretched in the said fixing hole fix with said printed circuit boards solder, the tin of molten condition is filled said groove after injecting said fixing hole in the welding region, thereby increases the bonding area of said shell and said printed circuit board (PCB); Strengthened the bonding strength of said shell; Thereby prevent that public connector is forced upwardly or extrudes owing to insufficient strength makes said fixing feet downwards when inserting shell, avoided the whole casing displacement, finally cause the contact disconnection of said splicing ear and printed circuit board (PCB) and the phenomenon of the electric connector generation signals hit that causes.

Embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.
See also Fig. 3, Fig. 4 and Fig. 5; The utility model electric connector 100 is installed on the said printed circuit board (PCB) 200, comprises shell 1, insulating body 2 bodies and splicing ear 3, and said splicing ear 3 is installed on the said insulating body 2 and with said printed circuit board (PCB) 200 and electrically connects; Said insulating body 2 is fixed in said shell 1 inside; Said shell 1 is fixed on the said printed circuit board (PCB) 200, and the rear end of said shell 1 is provided with several fixing feet 11, and present embodiment is provided with two said fixing feet 11.One end of said fixing feet 11 is fixedly connected with said shell 1, and the both sides of the other end are and offer groove 11a symmetrically.Said printed circuit board (PCB) 200 offers fixing hole 201, and said fixing feet 11 stretches in the said fixing hole 201 and fixes formation welding region 202 with said printed circuit board (PCB) 200 scolding tin.Said welding region 202 covers said fixing hole 201 and coats said groove 11a, makes the bonding area between said fixing feet 11 and the said printed circuit board (PCB) 200 obtain increasing like this, thereby strengthens the bonding strength between said shell 1 and the printed circuit board (PCB) 200.
