Electric connector

The relevant a kind of electric connector of the utility model refers to a kind of being applied in the notebook computer especially, and what be used to connect floppy disk, hard disk drive or CD drive and computer main board increases the type electric connector.

In electronics industry, electric connector is installed on the printed circuit board (PCB) usually with connecting circuit plate and other electronic installation.Electric connector comprises plug and socket, and every kind of connector is equipped with the insulating body of accommodating conducting terminal.For fear of external electromagnetic wave interference signal, make terminal energy normal transmission electric signal, electric connector also is provided with shading member usually.This shading member is necessary for ground state, derives with the electrostatic charge that will accumulate thereon, makes shading member keep electronegative potential could produce good shield effectiveness.

Be United States Patent (USP) the 4th, 943 as shown in Figure 1, a kind of existing electric connector that is disclosed for No. 244, it comprises shading member 1 ', insulating body 2 ', buckling piece 3 ' and terminal 4 ' etc.Wherein, insulating body 2 ' is provided with a pedestal 21 ', and its place ahead is provided with docking section 20 ', and docking section 20 ' is provided with some accepting holes 22 ', it is interior to contact with the butt joint connector terminals that terminal 4 ' one end is contained in accepting hole 22 ', and the other end then is welded on the circuit board.Shading member 1 ' is installed on the front portion of insulating body 2 ' along the arrow A direction, and its radome 10 ' encase docking section 20 ' around side and stay an opening and dock electric connector and dock.Simultaneously, in order to be grounded, shading member 1 ' downside is provided with a ground strip 11 ' and is stretched in insulating body pedestal 21 ' bottom backward with adjacent with buckling piece 3 ', buckling piece 3 ' is the rear portion that is installed on insulating body pedestal 21 ' along the arrow B direction, and the location hole 23 ' that the shell fragment 31 ' of buckling piece 3 ' springs on the pedestal 21 ' automatically during installation breaks away from insulating body 2 ' to prevent buckling piece 3 '.Simultaneously, buckling piece 3 ' engages with ground strip 11 ', and the button pin 30 ' of buckling piece 3 ' is fastened on button set on the printed circuit board (PCB) and holds hole (not icon), thereby the fixing electric connector is realized shading member 1 ' ground connection simultaneously in printed circuit board (PCB).

Yet, this existing electric connector, its shading member 1 ' is that the integrated punching moulding forms with ground strip 11 ', has produced too much clout in manufacturing process, has not only caused very big waste of material, and has increased the burden of handling waste material.In addition, when electric connector is that inner setting of matching computer adopted when increasing the type structure, for preventing to plug unstable phenomenon, make insulating body adopt the structure of both sides protrusion the buckling piece reach usually, the structure of then above-mentioned shading member and ground strip one is difficult to carry out.Therefore the path of above-mentioned shading member ground connection and structure still have improved necessity in fact.

The purpose of this utility model is to provide a kind of being installed on to increase the type electric connector on the circuit board, and this electric connector has grounding assembly simple in structure, easy to manufacture, and can make electric connector have good ground connection effect.

The purpose of this utility model is achieved in that electric connector includes members such as insulating body, shading member, terminal group and locking part, and wherein insulating body is provided with a microscler slot, and its both sides are provided with installation portion; Shading member is installed on the part that insulating body has slot, and electromagnetic shielding action can be provided; Terminal group is incorporated into insulating body, and it includes plurality of terminals, and wherein terminal one end extends in the slot of insulating body, and the other end then stretches out to combine with circuit board from its bottom; Locking part is assembled on the installation portion of insulating body, so that electric connector is immobilizated in circuit board, and electrically connect with the earthed circuit of circuit board, extend at least one shell fragment from the locking part one, this shell fragment has the elastic contact part that can be connected on the shading member, conductive path between the earthed circuit of shading member and circuit board is provided by this shell fragment and locking part, thereby reaches good ground connection effect.

Compared with prior art, the structure of each member of the utility model electric connector is simpler, and it is easier to make, and realizes preferable ground connection effect by contacting with shading member with the integrated shell fragment of locking part.

The utility model is described in further detail below in conjunction with drawings and Examples.
