Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers in particular to the electric connector that electrically connects circuit board and electronic building brick.

[background technology]

Be used to electrically connect the electric connector of circuit board and electronic building brick in the prior art, generally comprise an insulating body with plurality of terminals hole, plurality of conductive terminals is contained in the corresponding terminal hole; Conducting terminal is stamped to form by metal sheet band usually, inserts in the terminal hole when assembling, by swing, is broken off with the fingers and thumb disconnected between terminal and the strip.Like this, make in the process of terminal, a large amount of metal materials are wasted, and have increased production cost.

Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of novel electric connector, save metal material, and intensity is higher.

For achieving the above object, the utility model electric connector comprises: an insulating body, have several terminal holes, and the aperture of terminal hole second end is greater than the aperture of first end; Several spring conducting terminals, lower end external diameter are greater than the upper end external diameter, and greater than the aperture of terminal hole first end, described spring conducting terminal lower end is contained in corresponding terminal hole second end, and described spring conducting terminal upper end is contained in corresponding terminal hole first end; Several tin balls are contained in above-mentioned terminal hole second end.

Compared with prior art, the utility model electric connector utilizes the spring that forms by the wire coiling as conducting terminal, has saved material, and has had higher intensity.

[embodiment]

As shown in Figure 1, the utility model electric connector comprises an insulating body 1, some spring conducting terminals 2 and some tin balls 3.

As shown in Figure 2, insulating body 1 has several terminal holes 10, and terminal hole 10 is cylindric, and terminal hole first end 101 apertures are less than second end, 103 apertures.There are a ramped shaped or stair-stepping transitional region 102 between first end 101 and second end 103.

As shown in Figure 3, spring conducting terminal 2, one end 22 external diameters are greater than the external diameter at other position 21, and an end 22 is the lower end, are the upper end with respect to other position 21 of lower end 22.

As shown in Figure 4, several spring terminal 2 correspondences are contained in the terminal hole 10.Lower end 22 external diameters of spring conducting terminal 2 are greater than the aperture of terminal hole first end 101, so when spring conducting terminal 2 is assembled into terminal hole 10 from the bottom to top, lower end 22 is held by the transitional region 102 of terminal hole 10 and fixes, and has prevented that spring conducting terminal 2 from up moving.Lower end 22 external diameters of spring conducting terminal 2 are more bigger than terminal hole second end 103 apertures, when spring conducting terminal lower end 22 is located in terminal hole second end 103, there is interference effect between the two, prevented that spring conducting terminal 2 from spinning off from terminal hole second end 103 easily.The upper end 21 of spring conducting terminal 2 is revealed in the outer surface of insulating body 1, to contact with electronic building brick (not shown) compression.

As shown in Figure 1, tin ball 3 is contained in terminal hole second end 103, and the slightly larger in diameter of tin ball 3 is in the aperture of terminal hole second end 103, both interference engagement, and tin ball 3 is fixed in terminal hole second end 103.After spring conducting terminal 2 is assembled into terminal hole 10 from the bottom to top, again tin ball 3 is assembled into terminal hole second end 103, tin ball 3 makes 22 compressions of spring conducting terminal lower end.

As shown in Figure 5, after the 3 ' fusion of tin ball, spring conducting terminal 2 stretches, and reverts to the state shown in Fig. 4, and spring conducting terminal lower end 22 firmly is connected on the circuit board 4, electrically connects with circuit board 4.And the upper end 21 of spring conducting terminal 2 contacts with electronic building brick (not shown) elasticity of compression, and electric connector electrically connects circuit board 4 and electronic building brick.

Electric connector of the present utility model, its spring conducting terminal 2 forms by the wire coiling, saved material, and intensity is higher.
