Description of drawings
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, wherein:
Fig. 1 is the part-structure figure according to the connector with electrostatic discharge protection structure of the utility model one embodiment.
Fig. 2 is the connector schematic diagram according to present embodiment.
Embodiment
Present embodiment utilizes the principle of point discharge, on the shell of connector and pin lead, the adjacent broached-tooth design of sharp end is set, guide electrostatic charge to discharge whereby, or electrostatic current is guided on the shell, avoid electrostatic current to enter internal circuit and cause the damage of chip or circuit at this place.
Fig. 1 is the part-structure figure according to the connector with electrostatic discharge protection structure of the utility model one embodiment, as shown in Figure 1, comprise lid 110 and four pin leads 120 in the connector, lid 110 comprises four broached-tooth designs 112, correspond respectively to four pin leads 120, each pin lead 120 all has broached-tooth design 122, and the sharp end 112a of the sharp end 122a of broached-tooth design 122 and broached-tooth design 112 is adjacent.Broached-tooth design 122 for example is formed in one with 120 in pin lead, and broached-tooth design 112 also for example is one-body molded with lid 110.
The number of pin lead 120 is then decided according to the kind of connector, is example with the USB connector, then is four pin leads, and it corresponds respectively to four pins, and so-called pin lead 120 promptly is the lead that is used for connecting the pin in the connector.Lid 110 mainly is made up of roof 115, sidewall 116 and 117, forms the lid of a ㄇ type structure above pin lead 120 with side.Pin lead 122 is to be arranged in roof 115, sidewall 116 and the 117 formed accommodation sections 119.112 of broached-tooth designs are connected on the roof 116 (broached-tooth design 112 also can be one-body molded with roof 116), and its sharp end 112a then extends to the direction of pin lead 120, and adjacent with broached-tooth design 122.It should be noted that the distance between sharp end 112a and the sharp end 122a is near more, its electrostatic protection effect is good more, and its distance is the placement rule that is subject to printed circuit board (PCB) mainly.
Utilize the principle of point discharge, the electrostatic current on the pin lead 120 or the electrostatic charge of being accumulated can be discharged at the sharp end 122a place of broached-tooth design 122 easily, and lead electrostatic current off to broached-tooth design 112 sharp end 112a.In the present embodiment, lid 110 can be connected in earth terminal (not illustrating) or be directly connected in the shell of connector (shell of connector also is ground connection usually), therefore electrostatic current can be directed to the shell or the earth terminal of connector, avoids causing the damage of internal circuit.
Then please refer to Fig. 2 about the relation between shell and the lid 110, Fig. 2 is the connector schematic diagram according to present embodiment, and connector 200 comprises shell 230, lid 110 and pin lead 120.Shell 230 covers on the lid 110, and shell 230 for example is integrally formed with 110 of lids, or is connected by syndeton, and present embodiment is not limited.Wherein, the broached-tooth design 112 on the lid 110 is arranged at the opening part of connector 200 near the rear end connecting line with 122 of broached-tooth designs on the pin lead 120, avoids influencing the leg structure on the connector 200.
In addition, it should be noted that, present embodiment is applicable to various connectors, for example RS232, mini USB (MINI-USB), high resolution multimedia interface (High-Definition MultimediaInterface, HDMI) connector, digital visual interface (digital visual interface, DVI) connector, SCART connector etc., present embodiment does not limit its range of application.As long as according to the technological means of the foregoing description, the pin lead one of them with shell on corresponding broached-tooth design is set, can utilize the electro-static discharge protective ability of the principle increase connector of point discharge.
In addition, thin bilge construction about broached- tooth design 112 and 122 can be done suitably to adjust according to the external form and the structure of connector, present embodiment is not limited to the structure that Fig. 1 illustrates, need only its broached- tooth design 112 and 122 and have the less sharp end of size respectively, and its sharp end is arranged at the effect that adjacent place can reach the lifting electro-static discharge protective ability.
In sum, the utility model utilizes broached-tooth design to increase the electro-static discharge protective ability of connector, so each pin in the connector all can be reached the lifting of electro-static discharge protective ability by the mode of point discharge, can significantly save the use number and the cost of protecting component for electrostatic discharge, the space of reducing its shared PCB simultaneously.In addition, the utility model also can be avoided more can be widely used on the various connectors because of using the situation of the electrical characteristic deviation that protecting component for electrostatic discharge caused.
