Abstract
The utility model discloses an electrical connector which consists essentially of an insulating main body and a plurality of conductive terminals stored inside the insulating main body, wherein the insulating main body has a lengthwise-elongated structure and is provided with a central groove in the lengthwise direction, the circuit board is stored inside the central groove, a plurality of terminal storage grooves are arranged on the two opposite side walls in the lengthwise direction of the insulating main body, the plurality of conductive terminals are stored inside the terminal storage grooves, two ends of the insulating main body are respectively provided with guide arms that extend upwards from the plane where the central groove is located, and a positioning groove is formed between the guide arms to allow the circuit board to be inserted therein and to assist to position the circuit board. When the circuit board is inserted into the central groove of the electrical connector, the guide arm can prevent the circuit board from vibrating after inserted into the central groove of the electrical connector, thereby ensuring the stability in electrical connection between the circuit board and the electrical connector.
Description
[technical field]
The utility model is about a kind of electric connector, refers to a kind of the have guiding device of good stability, the electric connector that power circuit board is pegged graft especially.
[background technology]
Along with the PC continuous expansion of application in the industry cycle, the electric connector technology that the power supply brain is used reaches its maturity.The electric connector of using for PC will develop to littler, more accurate direction.As in " the Properties of Card Edge Connector Spring/TabInterface " that published on May 28th, 2002 the 25th page to the 30th page promptly disclosed this trend.This kind bayonet connector is generally by a lengthwise shape body and be contained in this intrinsic plurality of conductive terminals and constitute, and this body is provided with a lengthwise shape drop-center, and circuit board then is contained in this drop-center, be provided with the plurality of terminals accepting groove in the vertical two opposite side walls of this body, conducting terminal is contained in these terminal containing slots, and United States Patent (USP) announces the 4th, 869,672,5,052,936,5,171,154,5,449,297,5,564, also disclosed this structure No. 931.Yet, there is the disappearance part in the structure of this existing bayonet connector, as shown in Figure 1, electric connector 9 includes body 90 and is placed in plurality of conductive terminals 91 in this body 90, when circuit board 8 inserts in the drop-center 92, because the width of drop-center 92 is bigger than the thickness of circuit board 8, so after circuit board 8 is inserted, do the time spent when being subjected to foreign impacts, circuit board 8 can produce vibration in drop-center 92, thereby may cause circuit board 8 because of producing loose contact between impact and the conducting terminal 91, and then influence the reliability of circuit board 8 and 9 electric connections of electric connector.So be necessary to design a kind of novel electric connector to overcome above-mentioned disappearance.
[summary of the invention]
The purpose of this utility model is to provide a kind of electric connector, and it can prevent that circuit board from producing vibration in the grafting process, and then guarantees the reliability that electrically connects between circuit board and electric connector.
The purpose of this utility model is achieved in that provides a kind of electric connector, it mainly comprises insulating body and is contained in the interior plurality of conductive terminals of this insulating body, wherein this insulating body is a lengthwise shape structure, be provided with drop-center with ccontaining circuit board along its longitudinally, be provided with the plurality of terminals accepting groove in this insulating body two opposite side walls, plurality of conductive terminals is placed in this terminal containing slot, the two ends of insulating body are respectively equipped with from the upwardly extending guid arm in plane, drop-center place, are formed for guiding the location notch that circuit board inserted and circuit board was carried out assist location between this guid arm.
Compared with prior art, the utlity model has following advantage: can prevent that by this guid arm structure circuit board from vibrating, and guarantees the stability that electrically connects between circuit board and electric connector behind the drop-center that inserts electric connector.

Fig. 2 is the combination schematic diagram of the utility model electric connector and circuit board.
Fig. 3 is the cutaway view along Fig. 2 III-III line gained.
[embodiment]
Consult Fig. 2 and Fig. 3, it is the combination schematic diagram of the utility model electric connector 1 and circuit board 2, this electric connector 1 includes lengthwise shape insulating body 10 and is contained in plurality of conductive terminals 14 in this insulating body 10, wherein insulating body 10 is lengthwise shape structures, along its longitudinally be provided with drop-center 11 with ccontaining circuit board 2 in wherein, and be provided with cross rib 110 in the appropriate position of drop-center 11, and on circuit board 2 to being provided with groove 21 in cross rib 110 places, this groove 21 two closes to prevent that circuit board 2 from mispluging in the drop-center 11 mutually with cross rib 110, be provided with plurality of terminals accepting groove 12 in these insulating body 10 vertical two opposite side walls 13,14 of plurality of conductive terminals are contained in these terminal containing slots 12, vertical two opposite side walls 13 two ends of insulating body 10 are provided with respectively from the upwardly extending guid arm 130 in plane, drop-center 11 place, be formed for guiding the location notch 131 that circuit board 2 inserted and circuit board 2 was carried out assist location between this guid arm 130, wherein the width of the location notch 131 of guid arm 130 is between the thickness of the width of drop-center 11 and circuit board 2, and the opening section shape of this location notch 131 is V-shape, this V-shape port can be guided circuit board 2 and be inserted, when circuit board 2 inserts in the electric connector 1, because electric connector 1 is provided with guid arm 130 structures, thereby when vibration takes place owing to himself thickness than the width of drop-center 11 is little in circuit board 2, this guid arm 130 can prevent that circuit board 2 from vibrating, thereby can guarantee the installation stability of circuit board 2 in the drop-center 11 of electric connector 1, and then guarantee the good electric connection of 1 of circuit board 2 and electric connector.
