Abstract
The utility model relates to an electric connector which comprises an insulating body with multi tin ball-holding parts and a terminal whose end form ball-holding active spaces with side wall of the tin ball-holding parts. With the utility model, tin balls are held in the tin ball-holding parts (holes or slots) and can move in the holding parts. The tin balls fall freely due to gravity before welding to ensure height of the tin balls and high welding quality.
Description
[technical field]
The utility model relates to a kind of electric connector, especially a kind of electric connector that is overlapped with the tin ball.
[background technology]
At present, the used electric connector of industry has dual mode usually with being connected of circuit board, a kind of is that terminal on the electric connector is welded direct on the circuit board, another kind is to overlap earlier scolder on connector terminals, weld mutually with circuit board by scolder, realize between terminal and circuit board electrically connecting and make.A kind of connected mode in back can be with reference to No. 200420059350.7 patent of China, a kind of overlap joint tin ball device of electric connector is disclosed in this patent, electric connector wherein is provided with a pedestal and several terminals, and pedestal is provided with the several terminals groove, and terminal is arranged in the terminal groove, the terminal groove bottom is provided with the tin ball groove that communicates with terminal groove, the tin ball is contained in wherein, and terminal is provided with protuberance, and this protuberance embeds in the tin ball, and the tin ball is fixed in the tin ball groove, and be connected with terminal.But the lap device of this tin ball, the cell wall of tin ball groove is straight, makes the tin ball be easier to come off, and the protuberance on the terminal embeds and can prevent the tin ball tin ball groove that comes off in the tin ball, but adding man-hour and inconvenience, also be difficult to the height of each tin ball of control, so processing difficulties.
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 convenient electric connector of making and effectively guaranteeing welding quality.
In order to achieve the above object, the utility model electric connector comprises insulating body and terminal, and insulating body is provided with some tin balls accommodation section, and the sidewall of terminal ends and tin ball accommodation section forms the movable tin ball of accommodating in receiving space wherein.
Compared with prior art, the utility model electric connector forms the movable tin ball of accommodating in receiving space wherein at the sidewall of terminal ends and tin ball accommodation hole or groove, the tin ball is contained in tin ball accommodation hole or the groove and can moves therein, the tin ball freely moves down because of gravity before welding, make the height that can effectively guarantee each tin ball when welding, welding quality is better.

[embodiment]
Below in conjunction with accompanying drawing the utility model electric connector is described further.
Please refer to Fig. 1, the utility model electric connector comprises insulating body 1 and terminal 2, insulating body is provided with plurality of terminals accepting hole 10 (certainly, one terminal accommodation holes only is shown among the figure, but but also array (not shown) in insulating body of this connector terminals accepting hole), terminal 2 is contained in wherein, terminal 2 comprises main part 20, extended downwards by main part 20 and be provided with the stop section 21 that is vertical shape and extend upward the contact site 22 of setting by main part, and this contact site 22 can connect mutually with butt joint electronic building brick (not shown).Simultaneously, on insulating body 1 outside, also be provided with terminal accommodation holes 10 and form the tin ball accommodation section that is communicated with, tin ball accommodation section is the tin ball accommodation hole 12 (then is tin ball holding tank if tin ball accommodation section is arranged at the outside of insulating body) that is arranged at the centre position of insulating body in the present embodiment, the sidewall 14 of tin ball accommodation hole 12 is the inclined-plane, the part opening of tin ball holding tank 12 can be sealed in stop section 21, makes the stop section 21 of terminal ends and the sidewall 14 of tin ball holding tank 12 form the movable tin ball 3 of accommodating in receiving space 16 wherein.
When electric connector is welded to the circuit board (not shown), because of being contained in the tin ball accommodation hole, also can move therein by the tin ball, tin club freely moves down because of gravity, make the height that when welding, can effectively guarantee each tin ball, welding quality is better, simultaneously, make also simplyr, need not consider that all tin balls are whether on sustained height.
Please refer to shown in Figure 2, be the utility model second embodiment, be with the first embodiment difference, terminal ends is by the main body of the terminal certain angle that bends inwards, make the stop section 21 ' of this inclination and the sidewall of tin ball holding tank form the movable tin ball of accommodating in receiving space wherein, it also can reach the described purpose of the foregoing description in implementation process.
Please refer to shown in Figure 3, be the utility model the 3rd embodiment, be that this terminal ends is by the main body 20 ' of terminal 90 degree that bend inwards with the second embodiment difference, make terminal ends horizontal, it also can reach the described purpose of the foregoing description in implementation process.
Please refer to shown in Figure 4, be the utility model the 4th embodiment, be that with the foregoing description difference the end of this terminal 2 ' stretches out and be horizontal, this helps terminal and circuit board is more effective welds together, and it also can reach the described purpose of the foregoing description in implementation process.
Please refer to shown in Figure 5, be the utility model the 5th embodiment, be with the foregoing description difference, tin ball holding tank 12 " sidewall 14 " be perpendicular, simultaneously, terminal ends is by the main body 20 of terminal " certain angle that bends inwards, make the stop section 21 of this inclination " with tin ball holding tank 12 " sidewall 14 " form the movable tin ball 3 of accommodating in receiving space 16 wherein ", it also can reach the described purpose of the foregoing description in implementation process.
Please refer to shown in Figure 6, be the utility model the 6th embodiment, be that this terminal ends is by main body 20 of terminal 90 degree that bend inwards with the 5th embodiment difference, make terminal ends horizontal, it also can reach the described purpose of the foregoing description in implementation process.
