Abstract
The invention relates to an electric connector which comprises a seat body, a plurality of conductive terminals, a plurality of abutting-pressing elements and rotating covers which are connected with abutting-pressing parts of the abutting-pressing elements in a pivoted mode. Fixed parts of the conductive terminals and locating parts of the abutting-pressing elements are located on a locating body, moreover the locating body, the assembled conductive terminals and the abutting-pressing elements are placed in an array-shaped insertion groove for locating, contact parts of the conductive terminals and the abutting-pressing parts of the abutting-pressing elements are exposed in a butting-joint space, and the concave part at the front end of the abutting-pressing part of each abutting-pressing element stretches into a corresponding shaft groove of each rotating cover and is positioned on the surface of a rotating shaft. Due to the fact that the conductive terminals and the abutting-pressing elements are designed to be separated, and the locating body is jointed between the conductive terminals and the abutting-pressing elements, force exerted on the abutting-pressing elements by the rotating shafts of the rotating covers when the rotating shafts rotate and press a flexible circuit board in an abutting-against mode, and The loss caused by damage to the wall face of the insertion groove in the base of the seat body when the abutting-pressing elements are stressed is reduced.
Description
Technical field
The invention provides a kind of electric connector, You Zhike effectively reduces the electric connector that the flexible circuit board of High-frequency Interference is used.
Background technology
In recent years because computer; the development of network and electronic information related industry technology is more and more quicker; make electronic correlation product miscellaneous; weed out the old and bring forth the new successively; and tend to compact gradually; be easy to carry about with one and direction that computing and transmission speed are accelerated strides forward; yet; in described electronic correlation product; the electronics spare part that all is provided with the difference in functionality effect in it is formed; therefore; can bring into play itself due function for making described electronics spare part; generally all can be with electric connector interface as the bridge that carries out the electrical signal transmission each other; so the signal transmission can design at the dual development that increases signal transmission quantity and volume microminiaturization usually especially with the designer of electric connector; so; the conducting terminal number is many and electric connector flexible printed wiring board (FPC, the F lexible Printed Circuit) pattern that volume is compact just arises at the historic moment, and is more and more extensively applied in computer and the peripheral electronic device thereof.And the high-frequency signals that transmits is more and more quick, relatively therefore, plant density connector, because its conducting terminal number increases and is densely distributed, as easy as rolling off a logly disturb owing to terminal has any turnover or crooked signal when causing high-frequency signals to transmit (such as the cross-talk of electrostatic interference, Electromagnetic Interference, impedance matching, noise jamming, adjacent conductive terminal etc.), and then cause frequency range and signal quality not to reach standard and influence the normal operation of electronic installation (as computer, the network equipment etc.).
In the patent specification of bulletin M304148 patent, though disclosed a kind of " electric connector that flexible circuit board is used ", please consult Fig. 7 simultaneously, Fig. 8, shown in Figure 9, this existing structure is earlier with the opening A1 assembling of rolled-up stock C by body A, the abutting part B1 front end of terminal B top is stretched in the notch C3 of rolled-up stock C at body A opening A1 place, and the contact site B2 of terminal B below is the opening A1 below that is positioned at body A, and weld part B3 and the welding of default motherboard of side are located in addition in body A to make contact site B2, again the anchor point C4 in the notch C3 is placed in the groove B11 of abutting part B1, because anchor point C4 does not embed in the groove B11 as yet, so, strutting piece D can be inserted in the holding part A2 of body A, and supporter D upwards supports to arrive in the support arm C2 of rolled-up stock C, anchor point C4 is embedded in the groove B11, can be firm hold rolled-up stock C, make the anchor point C4 of rolled-up stock C can not break away from the groove B11 of the abutting part B1 of terminal B, make the pressurization part C5 of rolled-up stock C simultaneously between the abutting part B1 and contact site B2 of terminal B, when rolled-up stock C starts or covers, can not drop and deviate from body A.
So, when the user carries out the electric connection of flexible circuit board E, the support arm C2 leading edge of its rolled-up stock C is earlier smooth in strutting piece D surface, then stir the pulling part C1 of rolled-up stock C, make support arm C2 along arc surface C21 track and rotation gradually, driving rolled-up stock C simultaneously makes outside the groove B11 of its abutting part B1 that can not break away from terminal B through anchor point C4, and then make rolled-up stock C be a release position that starts, flexible circuit board E can be inserted between the abutting part B1 and contact site B2 of terminal B, just can stir rolled-up stock C covers, making the pressurization part C5 of rolled-up stock C compress flexible circuit board E presses down, flexible circuit board E is held between the projection B21 of pressurization part C5 and contact site B2, and then make flexible circuit board E and terminal B form certain electric connection, weld part B3 and the default motherboard of side form transfer path in addition by contact site B2 again, so, namely this existing structure is the arc surface C21 that utilizes rolled-up stock C two side support arm C2 as can be known, make its rolled-up stock C form a rotary state, and shore the support arm C2 of rolled-up stock C by strutting piece D, in case fastening site C4 breaks away from outside the groove B11 of abutting part B1 of terminal B.
Be the Contraband type in above-mentioned its terminal of existing structure B side, except the contact site B2 that flexible circuit board E electrically connects, the abutting part B1 that the spacing rolled-up stock C in its top uses then forms a branch road with contact site B2, but abutting part B1 does not electrically connect with flexible circuit board E, its high-frequency signals transmission path is all by flexible circuit board E in use, contact site B2 conducting to weld part B3 to motherboard, but be to be best transmission path with straight line and the beeline of not having a turnover because of the transmission of high-frequency signals, the branch road place of its signal transmission path will produce the kelvin effect of noise jamming and electrostatic interference, so this kind side is the existing terminal B structural design of Contraband type, frequency range and quality when very easily causing signal to transmit do not reach standard and influence electronic installation (as computer, the network equipment etc.) normal operation.
So, how to solve the existing disappearance of electric connector when high-frequency signals transmits with not enough, be the direction place of being engaged in this journey improvement that the dealer desires most ardently.
Summary of the invention
