Abstract
The utility model relates to a terminal solder sphere placement structure of the electrical connector. The terminal includes a contact part, a locating part, a clamping part, and a connecting part used to connect the locating part and the clamping part. The clamping part includes plurality of clamping arms. Clamping spaces for keeping the tin materials can be formed among the clamping arms. The tin materials is implant into the clamping spaces and extrudes with the clamping arms, which forces the clamping arms move outward against each other and the clamping space is increased until the tin materials is clamped to a specified position. Simultaneously, firm clamping of the tin materials can be obtained through the interference fit of the clamping arms and the tin materials.
Description
[technical field]
The utility model is to plant ball structure about a kind of electric connector terminal, especially refers to a kind ofly be used to provide the electric connector terminal that electrically connects between microprocessor and the circuit board to plant the ball structure.
[background technology]
The existing electric connector that is used to electrically connect on microprocessor and the circuit board has following two kinds of terminal constructions usually, and promptly stitch shape terminal and surface paste the type terminal.Along with the continuous development of manufacturing technology, plant the playing skill art and in the industry cycle obtained popularizing, make the surface paste the type terminal and in the electric connector that microprocessor is used, also extensively adopt.As United States Patent (USP) the 6th, 095, No. 842, the 6th, 099, No. 321 and 6,267, No. 61 all is that the terminal that the existing electric connector of announcement is used is planted the ball structure.See also Fig. 1, terminal 7 is planted tin material 9 in advance in terminal ends 8 before welding with circuit board (not shown), and this plants the process of tin material 9 in advance, be earlier at terminal ends 8 coating one deck scaling powders,, make tin material 9 partial meltings and be fixed in terminal ends 8 through being heated to uniform temperature then tin material 9 pre-determined bit by its viscosity.
But, there is following shortcoming at least in the process that existing electric connector terminal 7 is planted tin material 9 in advance: at first, because terminal 7 sizes are less, when terminal ends 8 coating scaling powders, very easily misoperation taking place and making on the contact site 6 of terminal 7 also is stained with scaling powder, thereby cause terminal 7 contact sites 6 resistance to increase, and make the telecommunication transmission quality not good.Secondly, the technology of planting tin material 9 in advance is because of need make tin material 9 part hot melts, electric connector is heated and causes the residual stress its insulating body (not shown) in to be released, and can cause the insulating body torsional deformation in the time of seriously, and influence the integral solder quality of electric connector.In addition, utilize hot-melt technology and the mode of planting ball cannot say for sure to demonstrate,prove 9 in tin material same flatness preferably, thus also can cause and circuit board between failure welding.
[summary of the invention]
The purpose of this utility model is to provide a kind of can reduce manufacture difficulty, and can provide the terminal of the preferable welding quality of tool between electric connector and circuit board to plant the ball structure.
The purpose of this utility model is achieved in that this electric connector terminal plants ball structure and be provided with terminal, and terminal comprises contact site, location division and clamping part, and use and the connecting portion that is connected location division and clamping part.Clamping part comprises some clamping limbs, form the grasping part that to accommodate the tin material between this clamping limb, the tin material is implanted behind the grasping part and the clamping limb mutual extrusion, clamping limb is relatively outwards opened and increase grasping part until fixing tin material to both allocations, clamping limb is with tin material interference engagement and tight this tin material of clamping simultaneously.
Compared with the prior art, the utlity model has following advantage: the tin material is implanted the mode that terminal need not to adopt welding, thereby reduced manufacture difficulty, and electric connector Yin Wendu stretches height and produces the bad phenomenon of distortion when having avoided prior art tin material to be welded on terminal.

[embodiment]
Please in conjunction with consulting Fig. 2 and Fig. 3, this terminal 1 comprises the contact site 11 that electrically conducts in order to the pin (not shown) with microprocessor, the solid location division 12 of this terminal 1 in the insulating body (not shown) of electric connector of group, be used for the clamping part 14 of clamping tin material 2, and be used to connect location division 12 and clamping part 14 and be provided with the connecting portion 13 of groove 131.Clamping part 14 is tabular, and it is provided with two clamping limbs 141, and 141 of this two clamping limbs form the grasping part 147 around shape, and when spherical tin material 2 was not implanted, this grasping part 147 was less with respect to the size of tin material 2.Tin material 2 is implanted in grasping parts 147 processes, itself and clamping limb 141 mutual extrusion, and this clamping limb 141 has elasticity again, and then two clamping limbs 141 relatively outwards open under the effect of extruding force, make grasping part 147 increases.When tin material 2 entered grasping part 147 to both allocations, clamping limb 141 is clamping tin material 2 with tin material 2 interference engagement and closely.
See also Fig. 4 and Fig. 5, it is respectively the schematic diagram of second and third embodiment of the present utility model.Terminal 1 ' can be provided with from connecting portion 13 ' terminal horizontal shape and separately stretch out two flexible clamping limbs 141 ' of tool (as shown in Figure 4), this terminal 1 " also can be provided with from this connecting portion 13 " horizontal extended cross section, terminal both sides is L shaped clamping limb 141 ", and another clamping limb 141 of extending of vertical shape " (as shown in Figure 5).All the other structures of these two embodiments and function do not repeat them here as described in first embodiment.
Seeing also Fig. 6, is the 4th embodiment of the present utility model.Extend two clamping limbs 341 from connecting portion 33 terminal horizontal shapes, be provided with groove 3412 at each clamping limb 341 middle position, and the end of clamping limb 341 is towards extend the holding section 3411 with suitable length away from circuit board (not shown) direction, when terminal 3 was fixed in electric connector (not shown), holding section 3411 can be replaced mutually with the insulating body (not shown) of electric connector.Tin material 2 enters in grasping part 342 processes of 341 formation of clamping limb, and two clamping limbs 341 relatively outwards open until tin material 2 to both allocations, this moment tin material 2 part outer surfaces be placed in the groove 3412 and with its interference engagement.
By technological means of the present utility model, tin material 2 is implanted in the grasping part 147 of terminal 1 clamping part 14 formation, by terminal 1 clamping tin material 2 tight with the interference engagement of clamping part 14.Yin Xi material 2 is implanted terminals 1 and be need not to adopt the mode of welding, thereby has reduced manufacture difficulty, and electric connector (not shown) Yin Wendu stretches height and produces the bad phenomenon of distortion when having avoided prior art tin material 2 to be welded on terminal 1.
