As previously mentioned, in the urgent need to providing a kind of electric connector taking the little and lightning protection structure that useful life is longer of board area and there is this lightning protection structure.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of electric connector taking the little and lightning protection structure that useful life is longer of board area and have this lightning protection structure.
For solving the problems of the technologies described above, a kind of technical scheme that the utility model provides is: a kind of electric discharge lightning protection device, it comprises substrate, be arranged on the region of discharge on substrate, described region of discharge comprises and is arranged at the first conducting strip on substrate and second conducting strip spaced with the first conducting strip, the side of the first conducting strip is provided with some first points and some the first grooves be arranged between adjacent two first points, the side of the second conducting strip is provided with some second points and some the second grooves be arranged between adjacent two second points, first point of described each first conducting strip is contained in the second groove of the second corresponding conducting strip, second point of each second conducting strip is contained in the first groove of the first corresponding conducting strip, described first point and the second groove are spaced a distance, second point and the first groove are spaced a distance.
A kind of electric connector, it comprises interior circuit board, the region of discharge be arranged on interior circuit board, this region of discharge described comprises and is arranged on the first conducting strip on interior circuit board and second conducting strip spaced with the first conducting strip, the side of the first conducting strip is provided with some points, the side of the second conducting strip is provided with some grooves, described each point is contained in corresponding groove, and point and groove are spaced a distance.
Compared with prior art, the point of the first conducting strip of the utility model region of discharge is contained in the groove of the second conducting strip, and the area of whole region of discharge is reduced.
[accompanying drawing explanation]
Fig. 1 is the circuit diagram of the utility model electric connector.
Fig. 2 is the structure chart of the utility model electric discharge lightning protection device.
[embodiment]
The utility model adopts point discharge principle to realize shocking preventing technology.In electrostatics; when conductor is charged; conductive surface is given prominence to and sharp-pointed place, and CHARGE DISTRIBUTION, than comparatively dense, forms very strong electric field in its vicinity; the air ionization of this electric field just near tip; air after ionization becomes conductor, remains cation in the air after ionization, these residual cations will in and lightning voltage; and then eliminate the energy of thunderbolt voltage, protective circuit.
Please refer to shown in Fig. 1, circuit Figure 100 of electric connector, this circuit Figure 100 comprises physics end 10, cable end 20, electric capacity 30 and is connected in parallel on the electric discharge lightning protection device 40 at electric capacity 30 two ends.One end ground connection of this electric discharge lightning protection device 40 described, the other end is connected with the centre cap of secondary coil.
Consult shown in Fig. 2, the vibrational power flow of electric discharge lightning protection device 40 is on a circuit board 50, and this electric discharge lightning protection device 40 comprises the region of discharge 41 be arranged on circuit board 50.Described region of discharge 41 comprises the first conducting strip 42 and second conducting strip 43 spaced with the first conducting strip 42 that are made of copper.Described first conducting strip 42 is provided with some first points 420 facing to the side of the second conducting strip 43 and is arranged on the first groove 421 between adjacent two the first points 420.Described second conducting strip 43 is provided with some second points 431 facing to the side of the first conducting strip 42 and is arranged on the second groove 430 between adjacent two the second points 431.These first, second points 420,431 described and first, second groove 421,430 are isosceles triangle and arrange uniformly, and first, second groove 421,430 one-tenth " V " fonts.Described first point 420 is contained in the second groove 430, second point 431 is contained in the first groove 421, the D but the first point 420 and the second groove 430 keep at a certain distance away, second point 431 and the same D that keeps at a certain distance away of the first groove 421, this distance D described is between 0.03 millimeter to 0.05 millimeter.Described first, second point 420,431 each is contained in the second, first corresponding groove 430,421, and what such deploying saved circuit board utilizes area.When electric connector is struck by lightning, the bottom conducting at first of the first point 420 and the second groove 430, the bottom conducting at first of the second point 431 and the first groove 421, the surge current caused by thunder and lightning is converted into the electric arc of moment, thus carries out power conversion.
