Abstract
The utility model relates to an electric connector which comprises an insulating body and a conductive terminal, wherein a terminal accommodating slot used for accommodating the conductive terminal is arranged on the insulating body. The conductive terminal comprises a weld part, and a gap is formed between the weld part and the terminal accommodating slot of the insulating body. The gap can increase the contact area of the weld position to form firm weld, and the bad phenomena of free weld, etc. can not be generated. The electric connector can be electrically connected with a circuit board stably.
Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of firm electric connector that welds especially.
[background technology]
The electric connector of prior art generally includes insulating body and conducting terminal (as shown in Figure 6), and conducting terminal is provided with weld part, by tin cream weld part is welded mutually with pad on the circuit board, realizes its electric connection.Yet, because the conducting terminal of this prior art is to be contained in fully in the insulating body, tin cream is positioned at the lower surface of weld part, just the lower surface of weld part and the pad of circuit board are welded during welding, the contact area of weld is less, and can inevitably produce bubble during the tin cream melted by heat in air.Therefore, can cause welding built on the sand, produce bad phenomenon such as empty weldering, influence the electric connection of electric connector and circuit board.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
[summary of the invention]
The purpose of this utility model is to provide a kind of electric connector, and its welding is firm, can not produce empty weldering phenomenon, can guarantee that electric connector and circuit board stably electrically connect.
In order to reach above-mentioned creation purpose, the utility model electric connector comprises insulating body and conducting terminal, insulating body is provided with terminal containing slot, be used for accommodating conducting terminal, conducting terminal comprises weld part, and is gapped between weld part and the insulating body terminal containing slot.
Compared with prior art, the utility model electric connector can increase the contact area of weld, makes welding firm, can not produce bad phenomenon such as empty weldering, can guarantee that electric connector and circuit board stably electrically connect.

[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.
Shown in please seeing figures.1.and.2 simultaneously, the utility model electric connector is used for connecting circuit plate (not icon) and electronic component (not icon), comprises insulating body 1 and conducting terminal 2, when electric connector was placed on the circuit board, conducting terminal 2 was parallel with circuit board.Wherein, insulating body 1 is provided with terminal containing slot, is used for accommodating conducting terminal 2, and terminal containing slot comprises the first terminal accepting groove 11 and second terminal containing slot 12.
First fixed part 22 that conducting terminal 2 comprises weld part 21 and is positioned at weld part 21 two ends and second fixed part 23 and the elastic contact part 24 that is connected with the butt joint electronic component.Wherein, weld part 21 in the form of sheets, weld mutually with circuit board pad (diagrammatic sketch mark) by tin cream (not icon), realize that it electrically conducts, weld part 21 is positioned at the first terminal accepting groove 11, and and gapped between the first terminal accepting groove 11, the gap is positioned at two sides (certainly, also can be positioned at a side of weld part) of weld part 21; First fixed part 22 is for being the upwards bending fixed part of bending, and second fixed part 23 is for being the horizontal fixed portion of level, and two fixed parts all are embedded in the insulating body 1, in order to fixed conductive terminals 2; Elastic contact part 24 extends obliquely from second fixed part, 23 1 ends, is positioned at second terminal containing slot 12, and protrudes in insulating body 1 upper surface, realizes electrically conducting to be connected with the butt joint electronic component.
Hot-air can pass the arrival tin cream during welding from the gap, makes the gap of passing after the tin cream fusion between weld part 21 and the first terminal accepting groove 11, upwards flows to other position of weld part 21 and can get rid of its inner bubble simultaneously.Cooling back tin cream can firmly be connected to weld part 21 pad on the circuit board, thereby strengthens welding effect.
Please refer to Fig. 3 and shown in Figure 4, certainly, also a through hole 211 can be set on the weld part 21 of conducting terminal 2, hot-air also can pass the arrival tin cream during welding from through hole, so that can upwards flow to the upper surface of weld part 21 after the tin cream fusion by this through hole 211 and get rid of its inner bubble simultaneously, make after its fusion welding more firm.
Certainly, the elastic contact part of conducting terminal also can extend upward and reflexed backward from second fixed part, one end in the foregoing description, protrudes in the insulating body upper surface, electrically conducts to be connected realization with the butt joint electronic component.(as shown in Figure 5)
The utility model electric connector is owing to be provided with the gap between weld part and the first terminal accepting groove, can upwards flow to other position of weld part and get rid of its inner bubble simultaneously after making the tin cream fusion, increased the contact area of weld, make welding more firm, and can not produce bad phenomenon such as empty weldering, can guarantee that electric connector and circuit board stably electrically connect.
