An electric connector comprises an insulation body and a plurality of terminals and solders collected in the insulation body. A plurality of spilling holes are arranged on the insulation body, thereby avoiding a short circuit caused by a contact of adjacent solders after melting and ensuring an excellent performance of the electric connector.
Description
Technical field
The utility model relates to a kind of electric connector, and especially a kind of scolder below is provided with the electric connector of permeability hole.
Background technology
As shown in Figure 1, 2, a kind of existing electric connector comprises the insulating body 2 that is provided with several terminal containing slots 1, and several are housed in terminal 3 and scolder 4 in the terminal containing slot 1.These terminal 3 two ends are respectively and dock electronic building brick (not drawing among the figure) contact site 5 that contacts and the weld part 7 that is welded on the circuit board 6, and this weld part 7 is a tabular, and fixes scolder 4 jointly with terminal containing slot 1.When this electric connector and circuit board 6 assemblings, earlier electric connector is placed on the circuit board 6, together by heating furnace, makes scolder 4 be molten into tin liquor then, weld pad 8 on terminal weld part 7 and the circuit board 6 is coupled together, and the welding that promptly forms electric connector and circuit board after the cooling is fixed.But after this electric connector was assembled on the circuit board, its scolder 4 was tall and thin type, confining force a little less than, thereby these terminal 3 easy breaking circuit plates 6 cause both can not form effective electric connection, influence the performance of electric connector performance; And this tin liquor 4 also may be climbed sharply to contact site 5, and the coating on the contact site 5 is covered, and influences electric connector and the contact performance of docking electronic building brick.
Summary of the invention
The purpose of this utility model is to provide a kind of electric connector, and it can guarantee that electric connector and circuit board form effectively and electrically contact, and guarantees the performance of electric connector performance.
The purpose of this utility model is to provide a kind of electric connector, and it can avoid tin liquor to climb sharply and be covered in the termination contact portion, guarantees electric connector and docks electronic building brick and effectively contact.
For achieving the above object, the utility model electric connector comprises insulating body and some terminal and scolders that is located in the insulating body, this insulating body is provided with some flashes hole, thereby can avoid being in contact with one another behind the adjacent solder fusing and form short circuit, guarantees the superperformance of electric connector.

Embodiment
Below in conjunction with accompanying drawing the utility model electric connector is further detailed.
Shown in Fig. 3,4, the utility model electric connector comprises the insulating body 10 that is provided with several terminal containing slots 12, and several are housed in terminal 20 and scolder 30 in the terminal containing slot 12.These insulating body 10 bottoms have protruded out a retaining tin portion 14 to terminal containing slot 12, and this retaining tin portion 14 and the common scolder accepting groove 16 that Open Side Down that forms of terminal containing slot 12 wall portions are to accommodate scolder 30 in wherein.These terminal 20 upper ends are provided with and dock the contact site 22 that electronic building brick (not drawing among the figure) contacts, and tail end is bent into the weld part 24 that horizontal formation and circuit board 40 weld mutually, and these weld part 24 central authorities are provided with through hole 26.During assembling, this terminal weld part 24 is positioned at scolder 30 belows, contains to live scolder 30 with scolder accepting groove 16.When electric connector when reflow is heated, scolder 30 is by the solid-state liquid state that becomes, thereby flows down in the through hole 26, is attached on the circuit board 40, makes terminal 20 and circuit board 40 mutual conductings.After this electric connector was welded on the circuit board 40, this scolder 30 was thicker, and embedding lives terminal weld part 24, formed effective conducting on the circuit board 40 thereby terminal 20 can be fixed on securely, guaranteed the superperformance of electric connector.And during assembling, this retaining tin portion 14 can stop tin liquor 30 upwards to be climbed sharply, thereby can guarantee terminal 20 and circuit board 40 firm fixation and can avoid tin liquor 30 to be covered in the termination contact portion 22 and cause and dock the electronic building brick loose contact.
Fig. 5,6 is depicted as second kind of execution mode of the utility model electric connector, its terminal weld part 50 also is horizontal, have appropriate gap 54 between this weld part 50 and terminal containing slot 52 walls, the time can allow tin liquor 56 from this gap 54, flow down and terminal 58 and circuit board 60 are electrically conducted in assembling.Because this scolder 56 is also thick and 50 embeddings of terminal weld part can be lived after should assembling, form effective conducting on the circuit board 60 thereby also terminal 58 can be fixed on securely, guarantee the superperformance of electric connector.
The utility model also is embodied as Fig. 7 and mode shown in Figure 8, and its electric connector also comprises insulating body 70 and some terminals 72 and scolder 74 that is located in the insulating body 70, and this insulating body 70 is provided with some scolder accepting grooves 76, to accommodate scolder 74.This terminal 72 approximate horizontal settings, and each terminal 72 all passes across corresponding scolder accepting groove 76, and the terminal part that is positioned at scolder accepting groove 76 is provided with through hole 78.This scolder 74 is positioned at terminal 72 tops.During assembling, this scolder 74 becomes tin liquor and flows down from through hole 78 through heat fused, so that terminal 72 and circuit board 80 are electrically conducted.Equally, this scolder 74 also can slightly and can be lived terminal 72 embeddings after the assembling, forms effective conducting on the circuit board 80 thereby also terminal 72 can be fixed on securely, guarantees the superperformance of electric connector.
It more than is several embodiments of the present utility model, the utility model electric connector also is embodied as other different modes, as the permeability hole that allows to flow out downwards behind the solder fusing is not limited to described above establish through hole, terminal ends at the terminal weld part and form structures realizations such as gap with the insulating body wall, also be embodied as other shape, as long as can reach the scolder that makes after the fusing flows out downwards and forms Welding Structure preferably, just can reach terminal is fixed on purpose on the circuit board securely, thereby also just can guarantee the superperformance of electric connector.
