[technical field]

The utility model relates to a kind of electric connector, refers to a kind of being used for and the electric connector that is connected of butt joint electronic component especially.

[background technology]

In order to the connector that connects between the forming circuit plate, Board-to-Board Electrical Connector for example, be by be fixedly arranged on respectively on two circuit boards the connection bull with connect parent part sleeve be combined into mutually, and the linking of its circuit promptly connects bull and connection parent part the sleeve male seat of fit and the terminal on the sleeve female seat is overlapped and form mutually by being located at, so its terminal then must with the circuit junction firm engagement of circuit board, can guarantee to constitute the connection of electric circuit.

Yet; because only being the solder side by each terminal, welds mutually known Board-to-Board Electrical Connector with the circuit junction of circuit board; and do not have connected structure between other and the circuit board; therefore regular meeting substitutes in the plug of carrying out circuit board; or being subjected to external force between circuit board does the time spent; its active force will produce terminal and pull, and will cause terminal and circuit junction to be separated, cause can't holding circuit normal operation.

As shown in Figure 1, be United States Patent (USP) the 6th, 132, the metal backing of No. 258 a kind of Board-to-Board Electrical Connectors that patent disclosed, it comprises body 26a, weld part 26b, contact jaw 26c and insertion tongue piece 26d, its weld part 26b, contact jaw 26c and insertion tongue piece 26d all are positioned at same one side of body 26a, as shown in Figure 2, the stereogram of the insulating body 22 that inserts for this metal liner plate 26, wherein body is inserted among the translot 22a, contact jaw then is fixed among the vertical slot 22b, and this metal backing all is stuck in the top of body, though insert on the tongue piece interference is arranged, but in the vertical direction also can not guarantee firm being fixed in the body of metal backing, thereby when it welds, the welding of influence and circuit board, and do not reach expected effect, and the metal backing complex structure of this electric connector, even more serious in the present electric connector structure defective that it brought under the situation of miniaturization day by day, can cause processing, assembly cost obviously increases, even can not be applied to present structure.

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 it can guarantee to weld preferably with circuit board, and simple in structure.

In order to reach above-mentioned creation purpose, the utility model electric connector comprises insulating body, conducting terminal and metal backing, insulating body is provided with main part, the two ends of autonomous body stretch out and are provided with connecting portion, conducting terminal is fixed in the terminal groove of insulating body, metal backing comprises body and the weld part and the fixed part that are extended by body two ends homonymy, and this weld part can be welded on the circuit board, and fixed part can fix with insulating body.

Compared with prior art, the metal backing of the utility model electric connector is connected stable with insulating body, and its in the vertical direction is not easy activity, thereby guarantees and the circuit board good welds, has guaranteed that electric connector is connected with the circuit board excellent electrical property.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further described.

To shown in Figure 5, the utility model electric connector comprises insulating body 1, conducting terminal 2 and metal backing 3 as Fig. 3.

Insulating body 1 comprises main part 10, main part 10 is provided with terminal groove 11, to accommodate conducting terminal 2, main part 10 mid portions are provided with a long and narrow storage tank 12, with with dock electric connector (not icon) and connect, the two ends of autonomous body 10 stretch out and are provided with connecting portion 13, to be connected with metal backing 3; Main part 10 ends are provided with holding slot 14 near medium position approximately in the horizontal direction, and holding slot 14 is positioned at connecting portion 13 tops.

Conducting terminal 2 is fixed in the terminal groove 11 of insulating body 1, and the weld part 20 of conducting terminal 2 stretches out in the bottom surface of insulating body 1 and stretches out in order to be welded on the circuit board (not icon).

Metal backing 3 roughly is " ㄈ " shape, comprise body 30, extend and be approximately perpendicular to the weld part 31 of body 30 from body 30 lower ends, and from the extended fixed part 32 in body 30 tops, weld part 31 is provided with at least three pads 311, so that welding is comparatively firm, fixed part 32 is perpendicular to body 30, it is tabular that fixed part 32 roughly is, and its terminal 320 sizes are less, terminal 320 both sides are provided with interference part 321, fixed part 32 and weld part 31 are positioned at the homonymy of body 30, body 30, form a receiving space 33 between weld part 31 and the fixed part 32.

When with metal backing 3 and insulating body 1 fixing, connecting portion 13 forms in the receiving space 33 between body 30, weld part 31 and fixed part 32, the part of fixed part 32 is positioned on the upper surface of connecting portion 13, its end 320 can insert in the holding slot 14 of insulating body 1, and interference part 321 and holding slot 14 interferences cooperate; Weld part 31 is positioned on the lower surface of connecting portion 13, can be welded on the circuit board.
