Abstract
The utility model is intended to provide an electric connector, which can connect a circuit board to the main board. It at least contains the insulating main body and a metal housing, The connector is characterized in that : at least an earthing strip that can be connected to the circuit board is positioned on the metal housing. The earthing strip connected to the circuit board is arranged on the metal case. It can not only prevent from the outer electromagnetic interference to affect the electric connector, but also conduct away the static on the circuit board that is butt jointed with the electric connector. Therefore the circuit board is ensured not only in normal application for optimum performance, but as well as to increase its usage life.
Description
[technical field]
The utility model relates to a kind of electric connector, refers in particular to a kind of electric connector that is provided with ground strip.
[background technology]
In electric connector field, especially in high frequency communication field of connectors, often use metal shell to fix the interior insulating body of electric connector, like this, metal shell can hide insulating body and be contained in several interior conducting terminals of this insulating body, (Electromagnetic Interference is EMI) to the influence of institute's transmission signal in the connector to reduce external electromagnetic interference whereby.Though can reduce outside electromagnetic interference but this class has the connector of metal shell, but the electronic building brick that docks with connector also can be subjected to extraneous electromagnetic interference and produce electrostatic induction, static on it but can not in time be led and be removed, and has a strong impact on the performance and the life-span thereof of butt joint electronic building brick.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
[utility model content]
The utility model purpose is to provide a kind of ground strip that has, and the timely static on the butt joint circuit board can be led the electric connector that removes.
To achieve these goals, the utility model electric connector can be connected to a circuit board on the motherboard, and it comprises an insulating body and a metal shell at least, and metal shell is provided with at least one ground strip that can connect mutually with circuit board.
Compared with prior art, the utility model electric connector is provided with metal shell, and on metal shell, be provided with the ground strip that connects mutually with circuit board, not only can prevent the influence of outside electromagnetic interference to electric connector, and can with circuit board that electric connector docks on static lead away, both can guarantee that circuit board normally uses with optimum performance, also can improve its useful life.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the utility model electric connector;
Fig. 2 is the assembly drawing of electric connector shown in Figure 1;
Fig. 3 is the combination schematic diagram of electric connector shown in Figure 2 and circuit board.
[embodiment]
Below in conjunction with accompanying drawing the utility model electric connector is described further.
Please consult Fig. 1 simultaneously to shown in Figure 3, the utility model electric connector 100 can comprise insulating body 20, metal shell 30 and conducting terminal 40 with a circuit board 50 connectors to motherboard (figure does not show), and metal shell 30 is assemblied in outside the insulating body 20.
Insulating body 20 is provided with the central slot 21 that can connect with circuit board 50, is provided with plurality of terminals accepting hole 22 in the both sides of this central authorities' slot 21, and conducting terminal 40 is accommodated wherein.The two sides of insulating body 20 convex with some projections 23 that are wedge shape.Simultaneously, be provided with reference column 24 in the location hole that is contained on the motherboard (figure does not show) in the bottom surface of insulating body 20.
Metal shell 30 is a monolithic construction, comprises top surface 300 and is positioned at the side surface 301 of top surface both sides, and top surface 300 is provided with the central slot 21 of insulating body 20 runs through mutually and runs through groove 31, but this runs through groove 31 power circuit boards 50 and passes.Stretch out at these both ends of running through a side of groove 31 and to be provided with two ground strips 32, this ground strip 32 can connect mutually with circuit board 50, ground strip 32 comprises the connecting portion 321 that the extension of groove 31 1 sides is provided with that runs through by metal shell 30, and, be provided with a pulling part 323 at these contact site 322 ends by the contact site 322 that this connecting portion 321 extends to form.The both side surface 301 of metal shell is provided with the draw-in groove 33 that matches with described projection 23, is provided with a guide channel 34 on these draw-in groove 33 sides, and the width of this guide channel 34 is a bit larger tham the width of described draw-in groove 33 and is a breach that does not seal.When being assembled to metal shell 30 on the insulating body 20, this guide channel 34 can be located described projection 23 and guide this projection 23 and is engaged in the draw-in groove 33.Simultaneously, metal shell 30 also one extends and is provided with both ends of the surface 38, and each end face 38 extends and be provided with weld part 35, and this weld part 35 is provided with a welding hole 36, be equipped with on this welding hole 36 can with motherboard (figure does not show) the tin ball 37 of welding mutually.
The utility model electric connector 100 is attached on the motherboard (figure does not show), reference column 24 is contained in the location hole on the motherboard (figure does not show), electric connector is positioned on the motherboard, and the back all is welded on the motherboard conducting terminal 40 and weld part 35 by welding.Circuit board 50 is plugged in the central slot 21 of electric connector insulating body 20, at this moment, the contact site 322 of the ground strip 32 of metal shell 30 is pressed on the junction 51 of circuit board 50 again.In use, metal shell 30 not only can prevent the influence of outside electromagnetic interference to conducting terminal in the electric connector, also the static that is accumulated on the circuit board 50 can be passed through ground strip 32 and metal shell timely, pass to the earth terminal (figure does not show) of motherboard again from weld part 35, static is led away, both can guarantee that circuit board 50 normally uses with optimum performance, also can improve its useful life.
